Technical Field

The present invention relates to a safety fence assembly and the like, and more particularly to a modular safety fence assembly primarily for use during high-rise building construction and associated anchors that can be used with the modular safety fence assembly.

Background

In the construction of buildings, particularly high rise buildings, it is common to erect safety fences or barriers around the perimeter of the building prior to the construction of any exterior walls. These fences can be used to prevent people, equipment and debris from falling off the edges of the building when the building is being constructed.

These safety barriers are usually modular and move from one work floor to another as construction progresses or from one work site to another. Thus, these security enclosures must be relatively easy to set up and remove, while causing relatively little damage to the floor and/or ceiling to which they are joined. This type of security fence generally includes a frame supporting a plurality of posts intermediate the fence panels.

While many attempts have been made to design improved safety barrier systems, there remains a need for a system that is easy to install and remove and that causes less damage to the floor and/or ceiling to which it is joined.

In the following description of various example structures in accordance with the invention, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration various example devices, systems, and environments in which aspects of the invention may be practiced. It is to be understood that other specific arrangements of parts, example devices, systems, and environments may be utilized and structural and functional modifications may be made without departing from the scope of the present invention. Also, while the terms "top," "bottom," "front," "back," "side," "back," and the like may be used in this specification to describe various example features and elements of the invention, these terms are used herein as a matter of convenience, e.g., based on the example orientations shown in the figures or the orientations during typical use. Also, the term "plurality," as used herein, means any number greater than one, either individually or in combination, up to infinity, when desired. Nothing in this specification should be construed as requiring a particular three dimensional orientation of structures in order to fall within the scope of the present invention. In addition, the reader's attention is directed to the fact that the drawings are not necessarily drawn to scale.

Aspects of the present invention relate generally to modular safety fence assemblies and associated anchors. According to various aspects and embodiments, the modular security fence assemblies and associated anchors described herein may be formed from one or more of a variety of materials, such as metals (including metal alloys), polymers, and composite materials, and may be formed in one of a variety of configurations, without departing from the scope of the invention. It should be understood that the modular safety rail assembly and associated anchors may comprise an assembly made of several different materials. In addition, the component may be formed by various forming methods. For example, the metal component may be formed by forging, manufacturing (forging), welding, molding, casting, stamping, machining, and/or other known techniques. Additionally, polymeric components, such as elastomers, may be manufactured by polymer processing techniques, such as various molding and casting techniques, and/or other known techniques.

The various figures in this application illustrate examples of modular safety fence assemblies and associated anchors for modular safety fence assemblies in accordance with the present invention. When the same reference number appears in more than one drawing, that reference number is used consistently in this specification and the drawings refer to the same or similar parts throughout.

As will be described in greater detail below, the present application illustrates an example of a modular safety fence assembly. An exemplary assembled modular safety fence assembly 10 is shown in fig. 1. As described herein, the modular safety fence assembly 10 in an embodiment generally comprises two portions. First, the modular safety rail assemblies described herein generally include one or more rail panel assemblies 21, shown generally in fig. 2-3D. Second, the modular safety fence assembly described herein generally includes one or more support post assemblies 43, shown primarily in fig. 4A-6E and 9-13B. As will be described below, support column assembly 43 may be anchored to the ground or concrete floor 52 using various anchor assemblies 50, and in other embodiments support column assembly 43 may be engaged by pressure between the floor and ceiling. The fence panel assembly 21 can then be attached to the support post assembly 43 to form the modular safety fence assembly 10.

Fence panel assembly

Referring now primarily to fig. 2-3D, an exemplary fence panel assembly 21 is shown. Fig. 2 shows a partially exploded isometric view of exemplary fence panel assembly 21, and fig. 3 shows a front view of exemplary fence panel assembly 21. The fence panel assembly 21 can be generally rigid, and in certain embodiments the fence panel assembly 21 can be inexpensive and/or lightweight.

The fence panel assembly 21 can include a body 20, the body 20 having a top rail 28 extending generally horizontally along a top portion of the body 20; a bottom rail 30 extending substantially horizontally along a bottom portion of the main body 20; and, in one embodiment, side rails 31 extending generally vertically along the outside of the body 20. In alternative embodiments, the side rails may be omitted to further reduce the weight of the fence panel assembly 21. Between the top rail 28 and the bottom rail 30, the body 20 further includes a mesh portion or mesh panel 24. In some embodiments, the grid 24 may be a "chicken wire; alternatively, another lightweight mesh wire, mesh fabric, mesh plastic, mesh composite, or other suitable material may be used in place of the wire mesh 24. For example, in certain embodiments, the mesh panel 24 may comprise a solid sheet of metal.

The fence panel assembly 21 can also include one or more reinforcing rods, such as the generally vertically extending rods 22 and the generally horizontally extending rods 26 shown in fig. 2 and 3. These rods can increase the stability of the fencing panel assembly 21 and can make assembly of the fencing panel assembly 21 easier. These rods can be used in place of the side rails and provide the necessary strength and integrity to the fence. In certain embodiments, the grid panel 24 may be sandwiched between the vertically extending rods 22 and the horizontally extending rods 26. For example, in certain embodiments, the fence panel assembly 21 includes a first outer layer including a plurality of generally vertically extending rods 22 spaced apart from one another along the length of the panel assembly 21; a second or intermediate layer made of mesh panels 24; and a third or inner layer comprising a plurality of horizontally extending rods 26 spaced from each other along the height of the panel assembly 21. In other embodiments, the order of the layers may be reversed. The grid panel 24 may be secured to the rods 22 and 26 by resistance welding in an automated manner or using any other suitable method. Welding the grid panels 24 to the poles provides additional structural rigidity and integrity to the rail assembly to make the assembly stronger to withstand greater loads applied to the rail assembly.

As mentioned above, the top rail 28 extends generally horizontally along a top portion of the body 20. As best shown in the detailed view of fig. 2A, the headrail 28 may have a generally square or rectangular cross-sectional shape; however, other cross-sectional shapes may be used, including, for example, circular and triangular cross-sectional shapes. The top rail 28 may also include a dependent lip 32 extending downwardly from the square or rectangular cross-sectional shape portion. In certain embodiments, the headrail 28, including the headrail dependent lip 32, may engage the vertical pole 22, the horizontal pole 26, and/or the grid 24. In certain embodiments, and as best shown in the detailed views of fig. 2 and 3C, the mesh 24 engages the dependent lip 32 and is locked between the lip 32 and the longitudinally spaced weld bead 34. In use, the top rail 28 is hung from the mounting hook of the support post, and the support post will carry the weight of the fence panel assembly 21.

Additionally, in certain embodiments, the headrail 28 may include a stiffening tube 36. As shown in FIG. 2, the stiffening tube 36 may have a cross-sectional shape that mimics, but is slightly smaller than, the internal cross-sectional shape of the headrail 28 such that the stiffening tube 36 may be inserted into the headrail 28. In certain embodiments, the stiffening tube 36 may extend substantially the entire length of the headrail 28. However, in other embodiments, the stiffening tube 36 does not extend the full length of the headrail 28. Advantageously, this may save weight and manufacturing costs.

As described above, the bottom rail 30 extends substantially horizontally along the bottom portion of the main body 20. As best shown in the detailed view of fig. 3D, the bottom rail 30 may have a generally L-shaped profile, although any convenient profile may be used. In some embodiments, the bottom rail 30 may engage the vertical rods 22, the horizontal rods 26, and/or the grid 24. As best shown in fig. 3D, the bottom edges of the panels of the grid 24 and the vertically extending rods 22 are secured to the bottom rail 30 by longitudinally spaced weld beads 38. Advantageously, this arrangement defines a rigid screed (kick plate) which may meet required building code standards. Additionally, in some instances, because the grid panel 24 extends substantially the entire height of the fence panel assembly, a user may not need to use additional nets or other similar security devices that may otherwise be required.

The fence panel assembly 21 can also include attachment loops 41, the attachment loops 41 can be used to secure the vertical edges of the grid panels 24 to the side rails 31 or the vertically extending rods 22 disposed over the vertical edges of the wire panels. In other embodiments, the mesh panel 24 may be attached to the side rails 31 using any suitable method, including, for example, welding.

The fence panel assembly can also include a pair of mounting openings 40 as shown in fig. 3. The mounting openings 40 may form open areas in the grid panel 24, and in some embodiments, the mounting openings may be located at corners where the side rails 31 meet the top rail 28. In certain embodiments, the mounting opening 40 is defined by a cut-out formed in the mesh panel or wire 24, and the mounting opening 40 may be covered by contact with the mesh panel or wire 24 to protect the user from injury. For example, as shown in FIG. 3, the opening 40 may be covered by a U-shaped molding 48. As will be discussed below, the mounting openings 40 can be used to engage the fencing panel assembly 21 with the support post assemblies 43, whereby the support post assemblies 43 will carry the weight of the fencing panel assembly.

Support column assembly

Referring now in more detail to the support post assembly 43, examples thereof are shown in fig. 4A-5F (fig. 4A-4C and 5A-5C show a first embodiment of the support post assembly and the anchor sock, and fig. 4D-4E and 5D-5E show a second similar embodiment of the fence post assembly and the anchor sock). In one embodiment, the support post assembly 43 may include a support post 44. The support column 44 may extend generally vertically upward and may have a height from the ground similar to the height of the panel assembly 21. The support post assembly 43 may also include a mounting hook 42 at an upper portion of the support post 44. Further, in certain embodiments (see, e.g., fig. 4D and 6C), to engage the lower portion of the fence panel assembly, the support post assembly can further include a lower mounting hook 45 at the lower portion of the support post 44. The mounting hooks can be used to engage the mounting openings 40 of the fence panel assembly 21, and in particular the fence post assembly 21.

The support post assembly 43 may also include a base 53. The base 53 extends generally horizontally and is configured to engage the floor 52 to which the support column assembly 43 is anchored. As shown in fig. 4A, the base 53 may be formed from two L-shaped brackets, however, any suitable base 53 may be used. For example, as shown in FIG. 4D, the base 53 may be a rectangular hollow tube. The support post assembly 43 may also include one or more brackets 51 connecting the base 53 to the support post 44. These brackets 51 may add additional rigidity to the strut assembly 43. As shown in fig. 4A-4B, the support post assembly 43 may include an aperture 55 through the base 53. And as shown in fig. 4A, the hole 55 may be formed by a cylindrical sleeve 76 welded to the base 53, however, other methods of forming the hole 55 may be used. For example, the base 53 may simply include an aperture 55 extending through the base 53.

The strut assembly 43 may be removably engaged with the floor 52 using an anchor assembly 50 extending through an aperture 55. As described above, the depth to which the anchor assembly 50 can penetrate the concrete floor 52 in high-rise buildings is generally limited to a certain depth due to the underlying service ducts, support cables and power cables buried in the concrete. In some cases, such pipes and cables are only one inch below the surface of the concrete floor 52. Thus, in the embodiments discussed herein, the depth of penetration of anchor assembly 50 through floor 52 may be limited to less than or equal to about 1 inch, or less than or equal to about 3/4 inches. The anchor assemblies discussed herein must also be able to withstand a certain amount of pulling force so that the assembly 10 does not inadvertently dislodge from the floor 52, especially in high rise building situations, which can lead to hazardous conditions. Thus, in certain embodiments, the anchor assemblies discussed herein may be capable of withstanding a load of at least 1000 pounds of tension, or at least 1500 pounds of tension. This is a tremendous improvement over many previous anchors which typically require 3 to 4 inches of penetration to ensure 1500 pounds of tension. In other words, the shallow anchor of the present invention can withstand a pulling force of the anchor that is at least equal to, if not greater than, four to five times the depth of the embedded concrete floor. In addition, unlike known anchors, where this may occur, the anchor of the present invention does not encounter or contact embedded cables or pipes within the concrete.

The anchor assembly 50 includes a bolt or rod 54 having an expander 56 at the bottom end of the bolt 54, the expander 56 having a tapered surface 57 that expands toward the bottom end of the bolt 54. The anchor assembly 50 also includes an anchor sleeve 58 through which the bolt or rod 54 may be inserted through the anchor sleeve 58. The anchor sleeve 58 includes a plurality of gripping segments 60. These grip segments may be formed of a metal or polymer material. The grip segment 60 has an inner surface 60A and an outer surface 60B. The inner surface 60A may be generally smooth and may have a generally curved shape. Additionally, in some embodiments the inner surface may be tapered such that the thickness of the grip segment 60 is greater at the top end than at the bottom end. As best shown in fig. 4C, 5B and 5C, the outer surface 60B of the gripping segment 60 may include a plurality of raised ridges 63 that form the grooves 61. These raised ridges 63 and/or grooves 61 may be used to engage the walls of a hole drilled into the floor 52. In one embodiment, the anchor sleeve may be less than 3/4 inches in height and less than 3/4 inches in diameter. The anchor sleeve may then be used with a corresponding receiving bore having a depth of 3/4 inches or less and a diameter of 3/4 inches or less. In other embodiments, the anchor sleeve 58 and/or the bore may have different sizes depending on the desired load. Generally, the diameter and/or height of the anchor sleeve may be increased where higher loads are required and decreased where lower loads are required. For example, in certain embodiments, the anchor sleeve 58 may have a diameter of less than about 1 inch, less than about 1.5 inches, less than about 2 inches, or less than about 3 inches. Holes can then be made in the corresponding diameters to fit the anchor sleeves 58. Similarly, in some embodiments, the height of the anchor sleeve 58 may be less than about 1 inch, less than about 1.5 inches, less than about 2 inches, or less than about 3 inches, or less than about 6 inches; and corresponding holes can be made at the correct depth to fit the anchor sleeve 58.

As best shown in fig. 4C and 5C, the grip segments 60 may be connected to each other by flexible, resilient members 59. In one embodiment, the elastic member 59 may include an elastic portion 62, or a plurality of elastic portions 62 extending between and/or bonded to each gripping segment 60. As shown in fig. 5C, the resilient member 59 includes a plurality of resilient portions 62 that extend between and engage the grip segments such that the inner surface of the anchor sleeve 58 has a generally circular cross-sectional shape.

A flexible, resilient portion 62 connects the plurality of gripping segments 60 to form a unified body. The anchor sleeve 58 may flex outwardly or transversely to the axis of the bolt 54 due to the flexible elastomeric material 62. Thus, when downward force is applied to the anchor sleeve 58, the anchor sleeve is forced over the tapered surface 57 of the expander 56, causing the gripping segments 60 to move outwardly at the bottom portion of the anchor sleeve 58. The bottom gripping element will first move outwardly so that the anchor first engages the inner surface of the receiving hole at the bottom where the concrete is strongest. The outward movement of the anchor sleeve (from the bottom of the receiving hole) thereby exerts increased pressure on the inner surface of the receiving hole in the floor 52. The outward pressure applied by the anchor sleeves 58 secures the bolts or rods 54 to the floor 52. In some embodiments, the size of the anchor sleeve is such that the top edge of the anchor sleeve is below the surface of the concrete floor 52. This sub-surface positioning allows the grip segment 60 to engage the inner wall of the receiving hole and may prevent the grip segment 60 from breaking the concrete floor at the upper edge of the receiving hole. The anchor sleeves of the present invention may be used with all types and conditions of concrete, including incompletely cured concrete.

In an alternative embodiment, the grip segment 60 of the anchor sleeve 58 may be connected by an elastic member 59 comprising one or more elastic bands 65. These elastic bands or O-rings 65 may be wrapped around the outer surface 60B of the gripping segments 60 to hold the segments 60 together. Such a configuration is shown in fig. 6A (in the closed position) and 6B (in the extended position). In addition, fig. 6C, 6D (in the closed position) and 6E (in the extended position) show the configuration with the fence post assembly 43 installed on the floor 52. In addition, this configuration of the anchor sleeve 58 is also shown in FIGS. 4D-4F and 5D-5F. The band 65 may be placed on the outer surface 60B of the grip segment 60 and/or in the outer groove 61 of the grip segment 60. Any number of straps 65 may be used to hold the segments together. In the exemplary embodiment of fig. 6A and 6B, at least two straps are used to hold the segments 60 together. In another exemplary embodiment, at least three or more bands are used to hold the segments 60 together.

Advantageously, the expander 56 is positioned to engage a bottom portion of the anchor sleeve 58. This allows the anchor sleeve 58 to expand first at its lower portion and engage the inner surface of the receiving hole at the bottom where the concrete is most strong. However, in other alternative embodiments, the anchor sleeve 58 may be configured to expand first at its tip, or the anchor sleeve 58 may expand substantially uniformly along the length of the anchor sleeve 58. For example, in one embodiment, the dilator 56 may be inverted and placed over the anchor sleeve 58. In this embodiment, the expander 56 can be moved down onto the anchor sleeve, causing the upper portion of the anchor sleeve 58 to expand first. In another embodiment, there may be a spreader 56 below the anchor sleeve 58 and an inverted spreader above the anchor sleeve 58. In such an embodiment, when the two dilators engage the anchor sleeve 58, the anchor sleeve 58 may expand substantially uniformly over its length. In other embodiments, the anchor assembly 50 may not include the spreader 56. In embodiments without spreader 56, the inner surface 60A of anchor sleeve 58 may be tapered such that the thickness of the grip segment is greater at the bottom end than at the top end.

The anchor assembly 50 may include additional components. As best shown in fig. 4A-5E, these additional components may have different shapes or sizes and/or may be omitted or combined with other components. As best shown in fig. 4C and 5B, the bolt or rod 54 may have a threaded portion 64 that receives a nut 66. As described above, the nut 66 may provide a downward force on the anchor sleeve 58 that expands outward as the anchor sleeve passes through the expander 56. In certain embodiments, the anchor assembly 50 may also include a washer 68 disposed below the nut 66. Additionally, in certain embodiments the anchor assembly 50 may include a stop flange 70 disposed below the washer 68. And in some embodiments, the stop flange 70 may engage the load gauge 72.

The load gauge 72 may be configured to indicate when the nut 66 has applied the desired load so that the user knows that sufficient load has been applied to move the anchor sleeve 58 down over the expander 56. The load gauge 72 may include a coil spring 74 locked in a cylindrical sleeve 76 or other bore 55. The load gauge 72 may also include a bottom flange 78 below the coil spring 74. A washer assembly 80 may be located between the anchor sleeve 58 and the flange 78. In certain embodiments, the gasket assembly 80 may include a resilient or rubber gasket 82 disposed over a metal gasket 84, and in other embodiments the gasket assembly 80 may include a single gasket. In some embodiments, the washer 84 may surround an upper portion of the anchor sleeve 58.

In use, the load gauge 72 may be used by an impact wrench or other similar tool moving the nut 66 downward until the coil spring 74 is no longer visible. The coil spring 74 is sized such that once the coil spring 74 is substantially within the cylindrical sleeve 76, the anchor sleeve 58 exerts sufficient lateral force on the hole in the floor 52 to retain the strut assembly 43 in the floor 52. An exemplary diagram of the load gauge 72 is shown in fig. 6D and 6E. As shown in FIG. 6D, the "G" portion of the coil spring 74 is visible. This indicates that the anchor sleeve 58 is not fully engaged within the bore and the nut 66 must be tightened further. Fig. 6E shows anchor assembly 50 after further tightening of nut 66. In this position, coil spring 74 is no longer visible, indicating that anchor assembly 50 is fully engaged within the bore.

To facilitate inspection and to confirm that the desired load has been applied, the coil spring 74 may be colored a unique color, such as red or yellow. If the color of the spring is still visible, this indicates that the spring has not been properly loaded and that an impact wrench is required to further drive the nut 66. In alternative embodiments, portions of the load gauge 72 and/or anchor assembly 50 may be omitted, such as the cylindrical sleeve 76 serving as a gauge. Advantageously, the coil spring 74 may also help reduce vibration of the nut 66, washers 68, 70, 80, and bolt 64, which may prevent them from loosening during use. In addition, the coil spring 74 may help maintain a downward force on the anchor sleeve 58. In alternative embodiments, the gauge may be omitted, and the spring may be painted or otherwise marked to indicate that the appropriate load has been applied. In another alternative embodiment, no color markings are used on the spring 74. In other words, the strut assembly may or may not be used with the gauge 72.

As shown in fig. 7-7C, once the user has installed support column assembly 43 into floor 52 using anchor assembly 50, the user attaches fencing panel assembly 21 to support column assembly 43. As shown in fig. 7-7C, mounting hooks 42 are inserted through mounting openings 40 to secure fence panel assembly 21 to support post assembly 43. As shown in fig. 7B, mounting hooks 42 can be sized such that two overlapping fence panel assemblies 43 can be mounted on a single mounting hook 42. The bottom portion of the fencing panel assembly 21 may be attached to the support post assembly 43 using locking cable ties 49 or other similar methods. The mounting hooks 42 will carry the weight of the fence panel assembly, allowing the fence panel assembly to be made in a lighter weight and more economical manner as described herein.

The anchor assembly 50 may include a safety feature to ensure that worn or old parts are not used. For example, in certain embodiments, the nut 66 and/or stop flange 70 may be painted a unique color that, when worn, will indicate that the component may need to be replaced. Additionally, when the nut 66 and/or flange 70 show significant signs of wear, this will further indicate that the assembly may need to be replaced. In other embodiments, the nut 66 and/or bolt or rod 54 may be manufactured such that if components of the anchor assembly 50 (e.g., the nut 66 and/or threaded portion 64) wear, the nut 66 can no longer be tightened. For example, as shown in FIG. 8A, the anchor assembly is shown in an unworn condition. However, as shown in FIG. 8B, the anchor assembly is shown in a worn condition in which nut 66 fails to provide the downward force required to press anchor sleeve 58 against spreader 56. These fault indicators designed into the system further provide additional safety to the system, which by its nature needs to be safe and to meet certain safety standards for high-rise buildings.

Grasping panel

In an alternative embodiment shown in fig. 9-13B, the support column assembly 43 may be a telescoping column 130 having a top end 133 extending to the ceiling 131 and a bottom end 135 extending to the floor 52. Similar to the method described above, the fence panel assembly 21 can be attached to the telescoping post 130, including using the mounting hook 42 that can be included on the telescoping post 130.

As shown in fig. 9-13B, the telescoping post 130 may include a first upper portion or inner tube or inner cylindrical tube 134 and a second lower portion or outer tube or outer cylindrical tube 136. As shown in fig. 9-13B, the first portion or inner tube 134 may have a reduced diameter as compared to the second portion or outer tube 136 such that the first portion 134 may slide within the second portion 136. Telescoping post 130 may also include a grip panel assembly 132 for holding inner cylindrical tube 134 in an extended position relative to outer cylindrical tube 136. The user may typically operate the telescoping column 130 by manually extending the inner column 134 upwardly relative to the outer column 136 until the telescoping column 130 spans substantially the entire distance between the floor 52 and the ceiling 131. The user may then use the grip panel assembly 132 to extend the inner tube 134 further upward until the telescoping post 130 is fully engaged between the floor 52 and the ceiling 131. In certain embodiments, the telescoping mast 130 may be anchored to the ceiling 131 at the top end 133 of the telescoping mast 130 similar to the anchoring shown in U.S. patent No.8,152,118, which is incorporated herein by reference. And in some embodiments the upper portion of the telescoping column 130 may be similar to the telescoping column shown in U.S. patent No.7,510,152, which is incorporated by reference.

The grip panel assembly 132 includes a grip panel 138 having a tube receiving opening 140. The tube-receiving opening 140 may have a polygonal shape, such as a hexagon, heptagon, octagon, nonagon, decagon, undecenon, or dodecagon. Due to the polygonal shape, the tube receiving portion defines a plurality of contact points 141, best shown in fig. 10A and 11, for contacting the reduced diameter portion of the inner tube 134. The plurality of contact points 141 may sufficiently retain the inner cylindrical tube 134 even if the tube 134 has a substantially circular cross-sectional shape or a substantially elliptical cross-sectional shape. In addition, the plurality of contact points 141 may prevent ovalization of the inner tube 34. This is because the load on the inner tube is distributed over multiple contact points 141. In alternative embodiments, the number of contact points may be six or eight points to further evenly distribute the load onto the tube, thereby preventing ovalization of the tube.

The grip panel 138 extends into an integral lever arm 142. The lever arm 142 may be angled with respect to the main body of the grip panel 138. The lever arm 142 defines a slot 144 for receiving an actuating rod or bolt 146, which rod or bolt 146 is carried by a bracket 148 secured to the outer cylindrical tube 136. The bracket 148 includes a nut 150, the bolt 146 is threaded into the nut 150 and the bolt 146 carries a retaining nut or bushing 152 to engage the grip panel 138 from one side of the lever arm 142. In certain embodiments, the grip panel assembly 132 may include a first washer 154 located on the nut 152. Turning the actuating bolt 146 in the opposite direction will engage the grip panel 138 on the opposite side of the lever arm 142 with the second washer 156 or retaining nut or end. Conveniently, a torque wrench or other similar device may be used to apply sufficient torque to lock the telescopic column 130 in place. In doing so, it will be appreciated that an additional point of contact is created between the actuation bolt 146 and the lever arm 142 of the grip panel 138.

In certain embodiments, the telescoping column 130 may include a load gauge 170, which may be configured to indicate when the telescoping column 130 has applied a desired load between the floor 52 and the ceiling 131. The load gauge 170 may include a coil spring 172 locked in the inner tube 134. The load gauge may also include a cap 174 secured to the inner tube 134. A portion of the inner tube 130 may be made visually distinct 176 from the remainder of the inner tube 130. For example, the visual difference may be a different paint color. The visual difference is shown as "L" in fig. 12B and 12C. In use, the load gauge 170 may be used to determine when the telescoping rod 130 is fully engaged. As the inner tube 134 moves upward, the cap 174 will cover a visually distinct portion 176 of the inner tube 134. Once the entire visually distinct portion 176 is covered by the cover 174, sufficient load has been applied to the telescoping post 130. Fig. 12B shows the load gauge 170 before sufficient load has been applied, with a visually distinct portion 176 of the inner tube 134 visible. Fig. 12C shows the load gauge 170 after sufficient load has been applied, with a visually distinct portion 176 of the inner tube 134 covered by a cap 174.

In certain embodiments, the nut 152 and/or other portions of the grip panel assembly 132 may include a wear system or visible wear indicia that may alert the user when the grip panel assembly 132 must be replaced. For example, the nut 152 may be painted or otherwise colored. After the color on the nut 152 disappears, this is an indication that the system may need to be replaced. Similarly, if the threads on the bolt 146 show signs of wear, this is also an indication that the system may need to be replaced. Also, if the slot 144 in the lever arm wears near the slot edge, this is an indication that the system may need to be replaced. In certain embodiments, the lever arm 142 may include a wear indicator, which may include one or more markings on the lever arm 142. These markings may indicate a specified number of uses that may be used before the grip panel assembly 132 must be replaced. When these markings wear out, the user will have a general indication of the number of uses remaining before the grip panel assembly 132 must be replaced. Further, in certain embodiments, and as is apparent from fig. 13-13B, the slot 144 may wear around the edges such that the retaining nut or bushing 152 moves into the slot 144 and cannot rotate further. This is an additional sign of wear. These fault indicators designed into the system further provide additional safety to the system, which by its nature needs to be safe and to meet certain safety standards for high-rise buildings.

The present invention is disclosed above and in the accompanying drawings with reference to a variety of examples. The intent served by the disclosure, however, is to provide an example of the various features and concepts related to the disclosure, not to limit the scope of the disclosure. One skilled in the relevant art will recognize that numerous variations and modifications may be made to the examples described above without departing from the scope of the present invention.
