Technical Field

The present disclosure relates to safety devices, and more particularly to fall protection systems and apparatus.

Background

Fall protection systems and devices are important safety devices for workers operating at potentially hazardous or even deadly heights. For example, to help ensure safety in the event of a fall, workers typically wear safety harnesses that are connected to a support structure having fall protection equipment such as lanyards, energy absorbers, self-retracting lifelines (SRLs), descenders, and the like. When a worker is connected to a support structure, the worker may be referred to as "binding. In order to maintain safe working conditions when working at high altitudes, the worker may always maintain at least one connection point with the support structure. Typically, a worker may use two connection points with the support structure to provide redundant safety and to ensure that at least one of the connection points remains connected to the support structure at all times.

The fall protection system can include various components for connecting a worker to a support structure (also referred to as an anchor). For example, snap hooks, shackles and quick couplers may have a movable gate that allows a worker to connect a worker's harness to a support structure and other fall arrest devices.

The second side of the base includes a fourth receiving portion and a fifth receiving portion extending outwardly from the base and spaced apart from each other to define a second side opening for coupling the connector to the safety harness, the fourth receiving portion defining a fourth receiving channel, the fifth receiving portion defining a fifth receiving channel, a second pin slidably connected to the fourth receiving channel and the fifth receiving channel and extending through the fourth receiving channel and the fifth receiving channel when the second pin is in the fully closed configuration. The second side of the base further includes a second locking mechanism connected to the fourth receiving portion, the second locking mechanism configured to releasably engage with the second locking notch of the second pin when the second pin is in the fully closed configuration to prevent slidable withdrawal of the second pin through the fourth receiving channel. The connection point of the at least one fall arrest device is received by one of a plurality of first side openings on a first side of the connector. The first pin connects the connection point to the connector when the first pin is in the fully closed configuration to prevent the at least one fall arrest device from being disconnected from the connector. A strong point of the harness is received by a second side opening on a second side of the connector, the second pin connecting the strong point to the connector to prevent disconnection of the harness from the connector when the second pin is in the closed configuration.

In one example, the present disclosure describes a method comprising positioning a pin of a connector according to claim 1 to a fully open configuration. The connector includes a pin having a locking recess and a base defining a first side. The first side of the base portion includes a plurality of first side receiving portions extending outwardly from the base and spaced apart from one another to define a plurality of first side openings for receiving one or more connection points of respective ones of the fall arrest devices. The plurality of first side receiving portions includes a first receiving portion defining a first receiving channel, the first receiving portion defining a first end of the first side; a second receiving portion defining a second receiving channel, the second receiving portion defining a second end of the first side; and a third receiving portion defining a third receiving channel, the third receiving portion being positioned between the first receiving portion and the second receiving portion. A pin is slidably connected to the plurality of first side receiving portions and spans the plurality of first side openings and extends through the first receiving channel, the second receiving channel, and the third receiving channel when the pin is in the fully closed configuration. The first side of the base portion further includes a locking mechanism connected to the third receiving portion, the locking mechanism configured to releasably engage the locking notch of the pin when the pin is in the fully closed configuration to prevent slidable withdrawal of the pin through the third receiving channel. When the pin is in the fully open configuration, the pin is received only by the first receiving channel and does not span the plurality of first side openings. The method further includes positioning a first connection point of a first fall arrest device within a first opening of the plurality of first side openings, the first opening defined by a separation distance between a first receiving portion and a third receiving portion; slidably advancing a pin into a partially closed configuration, wherein the pin is received by the first receiving channel and the third receiving channel and spans a first opening of the plurality of first side openings defined by the first receiving portion and the third receiving portion, the pin capturing a first connection point of the first fall arrest device to prevent the first fall arrest device from being disconnected from the connector; positioning a second connection point of a second fall arrest device within a second opening of the plurality of first side openings; and slidably advancing a pin to a fully closed configuration, wherein the pin is received by the first receiving channel, the second receiving channel, and the third receiving channel and spans the plurality of first side openings, the pin capturing a second connection point of the second fall arrest device to prevent the second fall arrest device from being disconnected from the connector.

Detailed Description

The present disclosure describes connectors for use with fall protection devices and various types of fall protection systems that can be used to provide fall protection to a single user working at a dangerous height. Fall protection apparatus may generally refer to a device for attaching a user (e.g., a worker) to a support structure in order to secure the user to the support structure in the event of a fall. Examples of fall protection devices include various shackles (also known as "snap hooks" or "snap hooks"), hook and loop irons, carrier sleeves, safety harnesses, fall arrest device self-retracting lifeline (SRL) or other devices capable of connecting and disconnecting a user to and from a support structure. The support structure may comprise an anchor or another structure capable of supporting the weight of a user in the event of a fall. In some examples, one or more connectors may be used to couple different pieces of equipment together. For example, one or more fall arrest devices, such as SRLs, may be connected to a worker's harness using connectors configured to secure the one or more fall arrest devices to a strong point of the harness. To ensure user safety, the connector must be reliable and able to withstand the force of a fall. Furthermore, to ensure proper attachment, the connector should be user friendly so that it is easy to install and confirm proper assembly.

Fig. 1-7 provide various views of an example connector 10, the example connector 10 being usable to connect a safety harness to one or more fall arrest devices, such as SRLs. In particular, fig. 1-4 are perspective views of an example connector 10, the connector 10 including a base 12, a first pin 18, and a second pin 20. Fig. 5A and 5B are cross-sectional views of fig. 1 through line a-a showing various features of the locking mechanism. Fig. 6A to 6C are perspective views of the first pin 18, and fig. 7A to 7C are perspective views of the second pin 18.

As used herein, the names of a first element, a second element, a third element, etc. are used only to distinguish one element from another. These terms are not used in a quantitative sense to imply or limit the total number of elements present, nor to imply a particular order in which the elements are numbered in the device.

In the example shown in fig. 1-4, the connector 10 includes a base 12, the base 12 providing a secure and reliable connector frame. As shown in fig. 1, the base 12 defines a first side 14 and a second side 16 of the connector 10. The first side 14 of the base 12 is the side facing the fall arrest device and includes a plurality of first side receiving portions 22A-22D formed as brackets extending from the first side 14 and spaced apart from one another to define a plurality of first side openings 28A-28C. Each of the plurality of first side openings 28A-28C may be configured to receive one or more fall arrest devices, such as SRLs. The second side 16 of the base 12 is a harness-facing side that includes a plurality of second side-receiving portions 30A and 30B, the second side-receiving portions 30A and 30B being formed as brackets that extend from the second side 16 and are spaced apart from one another to define a second side opening 32 (labeled in fig. 2) for coupling to a harness. In this example, the connector 10 provides a dual pin mechanism, wherein the first pin 18 is slidably and operatively connected to the plurality of first side receiving portions 22A-22D, and the second pin 20 is slidably and operatively connected to the second side receiving portions 30A and 30B independently of the first pin 18. However, in other examples, the connector 10 may include only the first pin 18 and utilize a portion of the second side 16 of the base 12 to attach the connector 10 to a safety harness.

As shown in fig. 1-4, the first pin 18 is configured to traverse the channel formed by the first side receiving portions 22A-22D to operatively open and close the first side openings 28A-28C. For example, the first side receiving portions 22A-22D may extend outwardly from the base 12, spaced apart from one another to define a plurality of first side openings 28A-28C. The plurality of first side receiving portions 22A-22D may include a first receiving portion 22A defining a first receiving channel 24A and a second receiving portion 22B defining a second receiving channel 24B. The first and second receiving portions 22A, 22B define respective first and second ends 26A, 26B for engaging the first side 14 of the pin 18. The plurality of first side receiving portions 22A-22D also includes at least one interior receiving portion (e.g., at least one of a third receiving portion 22C and a fourth receiving portion 22D) positioned between the first receiving portion 22A and the second receiving portion 22B that form the first end 26A and the second end 26B of the first side 14.

In the example shown in fig. 1-4, the plurality of first side receiving portions 22A-22D includes a third receiving portion 22C and a fourth receiving portion 22D positioned between the first receiving portion 22A and the second receiving portion 22B, respectively. However, in other examples, the connector 10 may include only one interior receiving portion (e.g., the third receiving portion 22A), or may include more than two interior receiving portions to deepen how the first side openings 28A-28C or fall arrest device is desired to be connected to the first side 14. Each of the third receiving portion 22C and the fourth receiving portion 22D defines a respective third receiving channel 24C and fourth receiving channel 24D.

The first side 14 may also include one or more locking mechanisms 34A and 34B, the one or more locking mechanisms 34A and 34B configured to releasably engage the first pin 18 when the pin is in the fully closed configuration (e.g., the configuration of fig. 1) to prevent the first pin 18 from being slidably withdrawn through one or more of the receiving channels 24A-24D (e.g., transitioning toward the fully open configuration). For example, as shown in fig. 1-4, the first side 14 includes a first locking mechanism 34A and a second locking mechanism 34B connected to the third receiving portion 22C and the fourth receiving portion 22D, respectively. In other examples, the first side 14 may include only one locking mechanism, or may be configured such that the first and second locking mechanisms 34A, 34B are connected to the first and second receiving portions 22A, 22B.

In some examples, the first and second locking mechanisms 34A and 34B may include a push button type release mechanism that interacts with one or more locking notches 36A and 36B defined by the first pin 18. For example, the first and second locking mechanisms 34A and 34B may each include a generally cylindrical locking channel 38, the locking channel 38 extending perpendicular to the respective third or fourth receiving channel 24C or 24D such that the locking channel 38 is in fluid communication with the respective receiving channel 24C or 24D. The locking channels 38 may each include a constriction 39 at one end, the constriction 39 defining a reduction in the diameter of the locking channel 38.

Each of the first and second locking mechanisms 34A, 34B may be configured to receive a biasing member 40 (e.g., a spring), an engagement member 42, and a rivet 44 that form the locking mechanism. Rivet 44 includes a shaft 46, shaft 46 having a head 48 opposite a deformable end 50. The coupling member 42 includes a tube portion 52 to which a first flange portion 54 and a second flange portion 56 are connected at opposite ends. A passage 58 extends through the engagement member 42 of the shaft 46 that receives the rivet 44. When the biasing member 40 and the engagement member 42 are both received within the locking channel 38, the biasing member 40 is configured to contact and engage the second flange portion 56 and the constriction 39 within the locking channel 38.

When fully assembled, rivet 44 extends through passage 58 of engagement member 42, the center of biasing member 40, and constricted portion 39 of locking passage 38. The deformable end 50 of the rivet 44 is then deformed to prevent the deformable end 50 from being withdrawn through the constriction 39. The head 48 and deformed end 50 of the rivet 44 thereby capture and retain the engagement member 42 and biasing member 40 within the locking channel 38.

During use, when in the uncompressed or locked state, the second flange portion 56 of the engagement member 42 protrudes into the receiving channel that is connected to the locking mechanism. For example, fig. 5A and 5B show cross-sectional views taken along line a-a of fig. 1. Fig. 5A illustrates an uncompressed or locked state of the first locking mechanism 34A within the third receiving portion 22C. As shown in fig. 5A, a portion of the second flange portion 56 extends into the third receiving channel 24C when in the locked position. While the third receiving channel 24C is sized to receive the shaft 60 of the first pin 18, the intrusion of the second flange portion 56 into the third receiving channel 24C effectively reduces the bore size of the third receiving channel 24C and prevents the shaft 60 of the first pin 18 from being slidably withdrawn through the third receiving channel 24C.

The first pin 18 includes one or more locking notches 36A and 36B formed along the shaft 60. The locking notches 36A and 36B may be sized such that the locking notch 36B may receive the second flange portion 56 of the engagement member 42 when the corresponding notch (e.g., the second locking notch 36B) is introduced into the third receiving channel 24C. When the locking recess 36B is properly aligned with the first locking mechanism 34A, the flange portion 56 of the engagement member 42 will remain in the locked position with the second flange portion 56 protruding into the third receiving channel 24C and the flange received by the locking recess 36, as shown in fig. 5A. With the locking mechanism 34A in the locked position, the second flange portion 56 prevents axial movement of the first pin 18 within the third receiving channel 24C.

To slidably withdraw the shaft 60 of the first pin 18 through the third receiving channel 24C, pressure is applied to the head 48 of the rivet to compress the biasing member 40 and allow the engagement member 42 to slide in the locking channel 38 toward the constriction 39. As engaging member 42 advances toward constriction 50, tube portion 52 becomes aligned with third receiving channel 24C, thereby clearing any obstruction from third receiving channel 24C from engaging member 42. This position may be considered a compressed position or an unlocked position and is shown in fig. 5B for the first locking mechanism 34A. With the second flange portion 56 no longer protruding into the third receiving channel 24C, the shaft 60 of the first pin 18 may be freely slidably advanced (e.g., transitioning toward the fully closed configuration) or withdrawn through the third receiving channel 24C (e.g., transitioning toward the fully open configuration) as long as the second locking mechanism 34B is not in the locked configuration.

In some examples, the first pin 18 may include one or more ramp portions 63A and 63B. As shown in fig. 5B, the first slope portion 63A extends from the front end of the shaft 60 to the first locking recess 36A, and the second slope portion 63B extends from the first locking recess 36A to the second locking recess 36B. The first ramp portion 63A and the second ramp portion 63B may allow the first pin 18 to advance past the first locking mechanism 34A and the second locking mechanism 34B without first unlocking the first locking mechanism 34A and the second locking mechanism 34B to advance the first pin within the first receiving channel 24A or the second receiving channel 24B. For example, the first ramp 63A may initially contact and depress the engagement member 42 of the first locking mechanism 34A to allow the first pin 18 to advance through the third receiving channel 24C until the first locking notch 36A is aligned with and engaged by the engagement member 42, at which point the engagement member 42 will seat within the first locking notch 36A, thereby preventing the first pin from being withdrawn from the third receiving channel 24C. If an urging force is applied to the first pin 18 (e.g., toward the fully closed configuration), the second ramp portion 63B will depress the engagement member 42 of the first locking mechanism 34A, and the first ramp portion 63A may likewise interact with the engagement member 42 of the second locking mechanism 34B to allow the first pin 18 to be urged toward the fully closed configuration through both the third and fourth receiving channels 24C, 24D.

In some examples, to assist in proper alignment of one or more locking recesses 36A and 36B of first pin 18 relative to engagement member 42 as first pin 18 is advanced through third receiving channel 24C, connector 10 may include an alignment pin 62 configured to engage a longitudinal slot 64 extending along a portion of shaft 60 of first pin 18. For example, the first receiving portion 22A may define a lateral channel 66, with the lateral channel 66 aligned and extending substantially perpendicular to the first receiving channel 24A. The first pin 18 may be advanced through the first receiving channel 24A until the longitudinal slot 64 is aligned with the lateral channel 66. The alignment pin 62 may then be inserted into the lateral channel 66 and the longitudinal slot 64, thereby preventing the first pin 18 from rotating within the first receiving channel 24A. By preventing rotation of the first pin 18, proper alignment of the locking notches 36A and 36B with the associated locking mechanisms 34A and 34B is ensured as the first pin 18 advances through the plurality of first side receiving channels 24A-24D.

Additionally, in some examples, the alignment pins 62 may also function as retaining pins to prevent the first pin 18 from being completely removed from the base 12 after installation. Preventing full or partial disassembly of the connector 10 may help prevent accidental loss of the first pin 18 or the second pin 20 or accidental switching of the first pin 18 and the second pin 20. In some examples, the alignment pin 62 may be secured within the first receiving portion 22A once the first pin 18 has been assembled. Suitable securing techniques may include, but are not limited to, welding, gluing, crimping, and the like.

In some examples, at least two locking mechanisms 34A-34D are included on each side 14 and 16 of the base 12. For example, the first side 14 includes a first locking mechanism 34A and a second locking mechanism 34B, and the second side 16 includes a third locking mechanism 34C and a fourth locking mechanism 34D. Each locking mechanism 34A-34D operates independently of the other locking mechanisms and may be configured to interact with a corresponding locking notch 36A and 36B or 72A and 72B on the first or second pin 18 or 20. Thus, taking fig. 1 as an example, when the first pin 18 is advanced to the fully closed configuration, both the first and second locking mechanisms 34A, 34B will inhibit axial movement of the first pin 18. This double locking mechanism requires the user to independently push the heads 48 of the respective rivets 44 of the first and second locking mechanisms 34A, 34B to unlock both mechanisms and thereby move the first pin 18. By including at least two locking mechanisms 34A-34D on each side 14 and 16, connector 10 provides a redundant safety feature and prevents accidental disconnection of connector 10 in the event that any individual locking mechanism 34A-34D is accidentally unlocked or damaged during use.

In some examples, the first and second locking mechanisms 34A and 34B may be connected to one or more of the interior receiving portions 22C and 22D, rather than to the first and second receiving portions 22A and 22B that form the first and second ends 26A and 26B of the first side 14. By forming the first and second locking mechanisms 34A and 34B within the inner receiving portions 22C and 22D, as described further below, the connector 10 can allow for a greater range of movement when the fall arrest device is attached to the connector 10. For example, the relative size and positioning of the first and second locking mechanisms 34A, 34B relative to the third and fourth receiving portions 22C, 22D can result in the receiving portions being somewhat large or bulky for the locking mechanisms to function properly and maintain sufficient structural integrity to withstand the effects of a fall. By incorporating a locking mechanism into the first side outer receiving portions 22A and 22B, a body associated with the locking mechanism can inhibit the ability of an attached fall arrest device, such as an SRL, to pivot about the first and second ends 26A and 26B of the first side. The reduced mobility of the SRL relative to the connector 10 during use of the fall protection system can result in kinking or increased resistance associated with extension or retraction of the lifeline. By incorporating the first and second locking mechanisms 34A and 34B into the interior receiving portions 22C and 22D, the first and second receiving portions 22A and 22B may be relatively thin and small in size, thereby allowing the connection points of the SRL to freely pivot about the first and second ends 26A and 26B defined primarily by the first and second receiving portions 22A and 22B. By allowing the SRL to pivot, the likelihood of the SRL kinking or otherwise increasing resistance is reduced.

As shown in fig. 1-4, the second pin 20 is configured to traverse the channel formed by the second side receiving portions 30A-30B to operatively open and close the second side opening 32. The second side 16 includes a pair of receiving portions including a fifth receiving portion 30A and a sixth receiving portion 30B extending outwardly from the base 12 and spaced apart from one another to define a second side opening 32 for coupling the connector 10 to a safety harness. The fifth receiving portion 30A and the sixth receiving portion 30B each define a respective receiving channel 68A and 68B configured to receive a portion of the shaft 70 of the second pin 20. Similar to the first pin 18, the shaft 70 of the second pin 20 may define at least one locking notch 72A and 72B configured to interact with one or more locking mechanisms 34C and 34D connected to either of the receiving portions 30A and 30B. The second pin 20 may be slidably transitionable from a fully open configuration (e.g., the configuration of fig. 2) to a fully closed and locked configuration (e.g., the configuration of fig. 1) in which the second pin 20 spans a second opening 32 defined by the fifth and sixth receiving portions 30A, 30B.

As shown in fig. 7A and 7B, the shaft 70 may include two locking notches 72A and 72B configured to engage with the locking mechanisms 34D and 34C, respectively. The operation of the locking mechanisms 34C and 34D may be substantially similar to the operation of the first locking mechanism 34A described above. In some examples, the second pin 20 may also define a ramp portion 73 at the forward end of the shaft 70 that extends all the way to the first locking recess 72A. The ramp portion 73 may allow the leading end of the second pin 20 to advance past the engagement member 42 of the fourth locking mechanism 34D until the first locking notch 72A is aligned with and engaged with the engagement member 42. In such examples, the ramp portion 73 may prevent the need to unlock the fourth locking mechanism 34D initially when the first pin 20 is initially introduced and advanced through the sixth receiving channel 68B.

In some examples, the fifth receiving portion 30A may further include an alignment pin 74 to assist in proper alignment of the locking recesses 72A and 72B relative to the engaging members 42 of the locking mechanisms 34C and 34D as the second pin 20 is advanced through one or more of the receiving channels 68A and 68B. The operation of alignment pin 74 may be substantially similar to the operation of alignment pin 62 described above with respect to first pin 18. For example, the fifth receiving portion 30A may define a lateral channel (not shown in the figures) that is aligned and extends substantially perpendicular to the fifth receiving channel 24A configured to receive the alignment pin 74. The second pin 20 may similarly define a longitudinal slot 78 extending along a portion of the shaft 70. The second pin 20 may be advanced through the fifth receiving channel 68A until the longitudinal slot 78 is aligned with the lateral channel. The alignment pin 74 may then be inserted into the lateral channel and the longitudinal slot 78, thereby preventing the second pin 20 from rotating within the fifth receiving channel 68A. Additionally, in some examples, the alignment pin 74 may also function as a retaining pin to prevent the second pin 20 from being completely removed from the base 12 after assembly.

Any suitable material or manufacturing technique may be used to form the components of the connector 10 (e.g., the base 12 or the first and second pins 18, 20). In some examples, the component may comprise a high strength metal or metal alloy, including, for example, heat treated aluminum zinc alloy, stainless steel, high strength composites, and the like.

The various features of the first side 14 and the second side 16 of the connector 10 may be integrated into the connector as shown and described, or may be separately incorporated into the connector. For example, the connectors described herein may include and realize the benefits of one or more features of the first side 14, such as positioning the locking mechanisms 34A and 34B within the interior receiving portions 22C and 22D of the first side 14, regardless of whether the connector 10 includes the second pin 12 or a different structure is used to connect the connector 10 to a user's harness. Additionally or alternatively, the connectors described herein may include and realize the benefits of one or more features of the second side 12, such as ease of attachment to a safety harness, regardless of whether the connector 10 includes all of the described features of the first pin 12.

In one example, the connector 10 described herein may be characterized as including a first pin 18 having a locking notch 36B and a base 12 having a first side 14 and a second side 16. The first side 14 of the base 12 may include a plurality of first side receiving portions including at least first, second and third receiving portions 22A-22C that each define respective first, second and third receiving channels 24A-24C. In such examples, the first receiving portion 22A may define a first end 26A of the first side 14, the second receiving portion 22B may define a second end 26B of the first side 14, and the third receiving portion 22C may be positioned between the first receiving portion 22A and the second receiving portion 22B. The plurality of first side receiving portions 22A-22C can be spaced apart from one another so as to define a plurality of first side openings (e.g., 28A-28C) configured to receive connection points of the fall arrest device. The first pin 18 may be slidably and operatively connected to the plurality of first side receiving portions 22A-22C such that when the first pin 18 is in the fully closed configuration, the pin spans the plurality of first side openings (e.g., 28A-28C) and extends through each of the first, second, and third receiving channels 24A-24C. The base 12 may include a locking mechanism 34A connected to the third receiving portion 22C, the locking mechanism 34A being configured to releasably engage the locking notch 36B of the first pin 18 when the pin is in the fully closed configuration to prevent the first pin 18 from being slidably withdrawn through the third receiving channel 24C.

As another example, the connector 10 described herein may be characterized as including a first pin 18 having a first locking recess 36B, a second pin 20 having a second locking recess 72B, and a base 12 having a first side 14 and a second side 16. The first side 14 of the base 12 may include a plurality of first side receiving portions including at least first, second and third receiving portions 22A-22C that each define respective first, second and third receiving channels 24A-24C. In such examples, the first receiving portion 22A may define a first end 26A of the first side 14, the second receiving portion 22B may define a second end 26B of the first side 14, and the third receiving portion 22C may be positioned between the first receiving portion 22A and the second receiving portion 22B. The plurality of first side receiving portions 22A-22C can be spaced apart from one another so as to define a plurality of first side openings (e.g., 28A-28C) configured to receive connection points of the fall arrest device. The first pin 18 may be slidably and operatively connected to the plurality of first side receiving portions 22A-22C such that when the first pin 18 is in the fully closed configuration, the first pin 18 spans the plurality of first side openings (e.g., 28A-28C) and extends through each of the first, second, and third receiving channels 24A-24C. The base may include a first locking mechanism 34A connected to one of the first, second, or third receiving portions 22A-22C, the first locking mechanism 34A configured to releasably engage with the first locking notch 36B of the first pin 18 when the pin is in the fully closed configuration to prevent slidable withdrawal of the pin through at least one of the first, second, or third receiving channels 24A-24C.

In such examples, the second side 16 of the base 12 may include a fourth receiving portion 30A defining a fourth receiving channel 68A and a fifth receiving portion 30B defining a fifth receiving channel 68B. The fourth receiving portion 30A and the fifth receiving portion 30B may be spaced apart from each other to define a second side opening 32. The second pin 20 is slidably and operatively connected to the fourth receiving portion 30A and the fifth receiving portion 30B such that when the second pin 20 is in the fully closed configuration, the second pin 20 spans the second side opening 32 and extends through the fourth receiving channel 68A and the fifth receiving channel 68B. The second side 16 of the base includes a second locking mechanism 34C connected to the fourth receiving portion 30A. The second locking mechanism 34C is configured to releasably engage the second locking notch 72B of the second pin 20 when the second pin 20 is in the closed configuration to prevent slidable withdrawal of the second pin 20 through the fourth receiving channel 68A.

As described herein, the connector 10 may be used to attach one or more fall arrest devices to a safety harness. Figures 8 and 9 illustrate an example fall protection system 80 that includes a connector 10 to a harness 82 and fall arrest devices 84A and 84B. Figure 8 shows an intermediate stage of assembly in which only the fall arrest device 84A has been attached to the connector 84A, and figure 9 shows the fall protection system 80 in a fully assembled stage in which both fall arrest devices 84A and 84B are attached to the connector 10.

As shown in fig. 8 and 9, the connector 10 may be attached to a strong point 86 of a harness 86. In some examples, the strong point of the harness may be constituted by one or more straps or webbing straps that form part of the harness. In the illustration of fig. 8, the strong points 86 of the harness 82 include two webbing straps that cross each other to provide a point for anchoring the harness 82 to other fall protection equipment. In some examples, harness 82 may be configured such that when harness 82 is worn by a user, strong point 86 is located in the middle of the user's upper back. This positioning of the high points 86 may provide sufficient comfort to the user during fall arrest and position the connector 10 and attached fall arrest devices 84A and 84B away from the user's workspace.

The strong points 86 may be connected to the second side 16 of the connector 10 by the second pins 20. For example, the second side opening 32 may be configured to receive a strong point 86 of the harness 82 when the second pin 20 is in the open configuration (e.g., the configuration of fig. 2). The second pin 20 may then advance under the hard spot 86 until the sixth receiving portion 30B receives the second pin 20. Once in the closed configuration (e.g., the configuration of fig. 1), the engagement members 42 of the third and fourth locking mechanisms 34C and 34D will engage with the second and first locking recesses 72A and 72B, respectively, of the second pin 20 to lock the pins in the second fully closed configuration. As such, the second pin 20 captures the hard spot 86 within the second opening 32, thereby preventing the connector 10 from being disconnected from the harness 82.

To remove the strong points 86 from the connector 10, the heads 48 of the third and fourth locking mechanisms 34C and 34D may be pressed to disengage the engagement members 42 of the locking mechanisms from the locking notches 72A and 72B. Next, the second pin 20 may be slidably withdrawn to return the second pin 20 to the open configuration (e.g., the configuration of fig. 2), thereby allowing the hard spot 86 to be removed from the second opening 32. In some examples, the second pin 20 may include a head 90 at one end that may be grasped by a user to assist in slidably withdrawing the second pin 20.

In some examples, by designing connector 10 to attach to strong points 86 via second pins 20, connector 10 may provide a number of advantages over conventional connectors. For example, the cylindrical shape of the shaft 70 of the second pin 20 allows the second pin 20 to advance smoothly under the hard spot 86. This in turn may limit the opportunity for the ribbon forming the strong points 86 to otherwise tighten within the connector 10 due to twisting. Further, the design of the second side 16 may require less effort by the user in order to attach the connector 10 to the harness 82 and ensure that the harness is properly positioned (e.g., donned) against the second pin 20. In contrast, a conventional connector connects to the strong point 86 via the base portion itself and attaches the fall arrest device to the base portion with a single pin or gate. Since conventional base portions are typically bulky, the user must pull on the strap of the strong points 86 to create enough slack to create a large enough opening to allow the base portion to slide under the strong points 86. Since the straps of the harness 82 may be relatively rigid to ensure that the high points 86 can withstand the forces associated with a fall, creating slack at the high points 86 may require significant effort by the user. Additionally, due to the shape and bulk of the conventional base portion, the base may be easier to grasp or twist the strap when the user attaches the base portion to the safety harness 82. Thus, by attaching the connector 10 to the strong point 86 via the second pin 20, the connector 10 may provide an easy and convenient mechanism for attachment to the harness 82, as described herein.

The fall arrest devices 84A and 84B may be connected to a first and second side of the connector 10 by a first pin 1814. The fall arrest devices 84A and 84B may comprise any suitable device designed to attach to a support structure and prevent a user from falling. An example fall arrest device may include: SRLs, such as 3M manufactured by 3M Fall Protection Business (3M Fall Protection Business)^TM SRL, vertical lifeline such as 3M manufactured by 3M Fall Protection services^TM

Mobile Rope Grab, safety Rope, etc.

Each of the plurality of first side openings 28A-28C can be configured to receive a connection point 88A and 88B of the fall arrest device 84A or 84B. The connection points 88A and 88B may include, but are not limited to, a closed connector, such as an eye bolt, a door type connector, such as a quick coupler or a shackle. The connection points 88A and 88B may include apertures sized to receive the shaft 60 of the first pin 18 such that when the first pin 18 is in a fully closed and locked configuration (e.g., the configuration of fig. 1 and 9), the first pin 18 captures the connection points 88A and 88B of the fall arrest devices 84A and 84B, thereby preventing the connector 10 from being disconnected from the fall arrest devices 84A and 84B.

In some examples, by including the first locking mechanism 34A on an interior receiving portion, such as the third receiving portion 22C, the connector 10 can provide a partially closed and locked configuration (e.g., the configuration of fig. 8), allowing the fall arrest devices 84A and 84B to be attached to the connector 10 independently of one another. For example, when in the fully open configuration (e.g., the configuration of fig. 2), the connection point 88A of the first fall arrest device 84A may be received within the first side opening 28A defined by the first and third receiving portions 22A, 22C. The first pin 18 is then slidably advanced through the first receiving channel 24A, the aperture of the connection point 88A and the third receiving channel 24C until the first locking notch 36A of the shaft 60 engages the first locking mechanism 34A to connect and lock the fall arrest device 84A to the connector 10.

The connection point 88B of the second fall arrest device 84A may then be received by one of the remaining plurality of first side openings, such as the first side opening 28C defined by the second receiving portion 22B and the fourth receiving portion 22D. The user may then depress the head 48 of the first locking mechanism 34A to disengage the engagement member 42 of the locking mechanism and allow the first pin 18 to be slidably advanced through the aperture of the connecting portion 88B toward the second receiving channel 24B. Once the first pin 18 is advanced to the fully closed configuration (e.g., the configuration of FIG. 1), the first locking mechanism 34A will engage the second locking notch 36B to capture and retain the two connection points 88A and 88B of the fall arrest devices 84A and 84B in the first and third side openings 28A and 28C. In the example, where the first side 14 further includes a second locking mechanism 34B, the second locking mechanism 34B will engage the first locking notch 36A once the first pin 18 enters the fully closed configuration.

To remove one or both of the fall arrest devices 84A and 84B from the connector 10, the heads 48 of the first and second locking mechanisms 34A and 34B may be pressed to disengage the engagement members 42 of the locking mechanisms. Next, first pin 18 may be slidably withdrawn to return first side 14 of connector 10 to the fully open configuration (e.g., the configuration of fig. 2), thereby allowing connection points 88A and 88B to be removed from first side openings 28A and 28C. In some examples, the first pin 18 may include a head 92 at one end, the head 92 may be grasped by a user to assist in slidably withdrawing the first pin 18.

In some examples, the first and second fall arrest devices 84A and 84B can exhibit a greater range of movement within the connector 10 by including the first and second locking mechanisms 34A and 34B within the inner receiving portions 22C and 22D opposite the outer first and second receiving portions 22A and 22B. For example, by including the first and second locking mechanisms 34A and 34B within the interior receiving portions 22C and 22D, the first and second receiving portions 22A and 22B forming the respective first and second ends 26A and 26B may maintain a relatively unobstructed or smaller volume than the interior receiving portions 22C and 22D. The apertures of the connection points 88A and 88B may be sized such that when connected to the connector 10 (e.g., the configuration of fig. 9), one or both of the connection points 88A and 88B may be allowed to pivot about the first and second ends 26A and 26B, respectively. For example, the connection point 88B of the second fall arrest device 84B may be able to rotate clockwise in fig. 9 such that the connection point slides on the second receiving portion 22B to align horizontally in fig. 9 (e.g., parallel to the longitudinal axis of the first pin 18) while still remaining captured within the first side opening 28C.

In some examples, the ability of connection points 88A and 88B to pivot about first end 26A and second end 26B of first side 14 can allow a greater degree of user mobility and safer operation of fall protection system 80 during use. For example, the fall arrest devices 84A and 84B are generally connected such that the devices are vertically aligned with respect to the user (e.g., as shown in FIG. 9). If a user traverses laterally from the support structure to which it is anchored, the fall arrest devices 84A and 84B may be pulled in a horizontal direction relative to the user (e.g., pulled in parallel relative to the central axis of the first pin 18). Absent the ability of one or more of the fall arrest devices 84A and 84B to pivot freely about the first end 26A or the second end 26B, the fall arrest devices 84A and 84B may be bundled within the plurality of first side openings 28A-28C. When a tether (e.g., lifeline) coupling the fall arrest devices 84A and 84B to the support structure is retracted and extended, such binding may result in an increase in resistance, thereby impeding the ability of the user to move freely relative to the support structure. Additionally or alternatively, in the event of a fall, such binding results in additional shock loading of the fall protection system 80, resulting in increased stress on one or more components to resist the fall of the user.

Figures 10 and 11 are flow diagrams illustrating an example technique for attaching more than one fall arrest device 84A and 84B to a safety harness 82 using the connector 10. The technique of figure 10 corresponds to attaching fall arrest devices 84A and 84B to connector 10, and includes positioning the first pin 18 of the connector 10 into a fully open configuration (e.g., the configuration of fig. 2) (100), positioning the connection point 84A of the first fall arrest device 84A within the first side opening 28A (102), slidably advancing the first pin 18 into a locked, partially closed configuration (e.g., the configuration of fig. 3 and 8) to capture the connection point 84A of the first fall arrest device 84A within the inner first side opening 28A (104), positioning the connection point 84B of the second fall arrest device 84B within the subsequent first side opening 28C of the connector 10(106), and slidably advancing the first pin 18 into a locked, fully closed configuration (e.g., the configuration of fig. 1 and 9) to capture the connection point 88B of the second fall arrest device 84B within the first side opening 28C (108).

As described above, the connector 10 may include a base 12 defining a first side 14, the first side 14 including a plurality of first side receiving portions 22A-22D having at least a first receiving portion 22A defining a first receiving channel 24A and a first end 26A of the first side 14, a second receiving portion 22B defining a second receiving channel 24B and a second end 26B of the first side 14, and a third receiving portion 22C defining a third receiving channel 24C and positioned between the first receiving portion 22A and the second receiving portion 22B.

In the fully open configuration (100), the first pin 18 may only be received within the first receiving channel 24A such that the first side opening 28A defined by the first receiving portion 22A and the third receiving portion 22C is open and accessible. In some such examples, the alignment pin 62 within the first receiving portion 22A may engage the slot 64 to prevent removal of the first pin 18 from the base 12.

Once in the fully open configuration (e.g., the configuration of fig. 2), the connection point 88A of the first fall arrest device 84A may be introduced into the first side opening 28A defined by the first and third receiving portions 22A, 22C (102), with the first pin 18 slidably advanced to a locked, partially closed configuration (e.g., the configurations of fig. 3 and 8) to capture the connection point 88A of the first fall arrest device 84A within the first side opening 28A (104). For example, the first pin 18 may be advanced through the aperture of the connection point 88A and into the third receiving channel 22C to capture the connection point 88A and prevent the fall arrest device 84A from disengaging from the connector 10. In examples where the third receiving portion 22C includes the first locking mechanism 34A, the head 48 of the first locking mechanism 34A may be depressed and the first pin 18 may slidably advance until the first locking notch 36A of the first pin is aligned with the first locking mechanism 34A. The head 48 of the first locking mechanism 34A may then be released such that the first locking recess 36A engages the engagement member 42 to effectively lock the first pin 18 in the partially closed configuration (e.g., the configuration of fig. 8) to prevent withdrawal of the first pin 18 from the third receiving channel 24C (e.g., toward the fully open configuration). Additionally or alternatively, the first pin 18 may include one or more ramp portions 63A and 63B, for example, a first ramp portion 63A extending from the front end of the shaft 60 to the first locking notch 32A. When a pushing force is applied to allow the first pin 18 to slidably advance toward the fully closed configuration, the ramp portion 63A may depress the engagement member 42 of the first locking mechanism 34A without requiring the user to manually depress the head 48 of the first locking mechanism 34A to reach the locked, partially closed configuration.

In some examples, with the first pin 18 in the locked, partially closed configuration, a user can conveniently attach the fall arrest devices 84A and 84B independently of one another without having to handle both devices simultaneously to attach them to the connector 10.

As described above, once the first fall arrest device 84A has been attached to the connector 10, the user may attach the second fall arrest device 84B to the connector 10 by introducing the connection point 88B of the second fall arrest device 84B into the other of the first side openings 28B or 28C (106), and then the first pin 18 can be slidably advanced to a locked, fully closed configuration (e.g., the configuration of FIGS. 1 and 9) to capture the connection point 88B of the second fall arrest device 84B within the other of the plurality of first side openings 28A-28C (108). For example, the connection point 88B of the second fall arrest device 84B may be introduced into the first side opening 28C defined by the second 22B and fourth 22D receiving portions. The first locking mechanism 34A may then be disengaged from the first locking recess 36A by depressing the head 48. In examples where the first pin 18 includes a second ramp 63B between the first and second locking recesses 36A, 36B, the second ramp 63B may automatically disengage the first locking mechanism when a pushing force is applied without manually depressing the head 48. The first pin 18 is then slidably advanced through the fourth receiving channel 24D (e.g., also by depressing the head 48 of the second locking mechanism 34B when the second locking mechanism 34B is present), connecting the aperture of the point 88B and the second receiving channel 24B. Once fully inserted, the first locking mechanism 34A will engage the second locking recess 36B to lock the first pin 18 in place, thereby capturing the first and second fall arrest devices 84A, 84B and preventing them from being disconnected from the connector 10. In examples where the first side 14 further includes a second locking mechanism 34B for redundant shielding, the second locking mechanism may engage the first locking recess 36A when the first pin 18 has been fully inserted into the base 12.

While the connection point 88B of the second fall arrest device 84B may be introduced into the first side opening 28B or 28C, in some examples, it may be preferable to retain the second fall arrest device 84B in the first side opening 28C to balance the assembly of the connector 10 and prevent the connector from twisting or binding during use. Additionally or alternatively, where the connector 10 includes both the first and second locking mechanisms 34A and 34B within the inner receiving portions 22C and 22D, having the second fall arrest device 84B within the first side opening 28C may allow the connection point 88B to pivot about the second end 26B (e.g., the second receiving portion 22B), as described above.

To remove the first and second fall arrest devices 84A, 84B from the connector 10, the heads 48 of the first and second locking mechanisms 34A, 34B can be depressed and the first pin 18 slidably withdrawn from the first side openings 28A, 28C to the free connection points 88A, 88B.

The technique of fig. 11 corresponds to attaching the connector 10 to the harness 82, and includes positioning the second pin 20 of the connector 10 into a fully open configuration (e.g., the configuration of fig. 2) (110), positioning the strong point 86 of the harness 82 within the second side opening 32 (112), and slidably advancing the second pin 20 into a locked, fully closed configuration (e.g., the configurations of fig. 1 and 8) to capture the strong point 86 within the second side opening 32 (114).

As described above, the connector 10 may include a base 12, the base 12 defining a second side 14, the second side 14 including fifth and sixth receiving portions 30A and 30B each defining receiving channels 68A and 68B. The fifth and sixth receiving portions 30A, 30B also define a second side opening 32 therebetween, the second pin 20 spanning the second side opening 32 when the second pin 20 is in the fully closed configuration (e.g., the configuration of fig. 1).

In the fully open configuration (110), the second pin 20 may only be received within the fifth receiving channel 30A such that the second side opening 32 remains open and accessible. In some such examples, the alignment pin 62 within the fifth receiving portion 30A may engage the slot 78 to prevent removal of the second pin 20 from the base 12.

Once in the fully open configuration (e.g., the configuration of fig. 2), the strong point 86 of the harness 82 may be introduced into the second side opening 32. Second pin 20 may then be slidably advanced under strong point 86 to a locked, fully closed configuration (e.g., the configuration of fig. 1 and 8) to capture strong point 86 within second side opening 32 (114). As described above, slidably advancing second pin 20 below strong point 86 relative to base 12 can provide several advantages, including making assembly of fall protection system 80 more convenient and easier to check for accuracy of assembly.

Once in the fully locked configuration, the third and fourth locking mechanisms 34C, 34D may engage the first and second locking recesses 72A, 72B to redundantly retain the second pin 20 within the base 12.

To release the harness 82 from the connector 10, the heads 48 of the third and fourth locking mechanisms 34C, 34D may be depressed and the second pin 20 may then be slidably withdrawn from the sixth receiving channel 68B to release the hard spot 86 from the second side opening 32.

Various examples have been described. These examples, as well as others, are within the scope of the following claims.
