Technical Field

The present invention relates to an access device, and more particularly to an access device having a lock and a lock status indicator.

Background

The present disclosure relates to an access device operable to selectively block and allow access through a barrier. The access device is exemplified as one of an entry function door lock, a privacy function door lock, and an intruder function door lock, and the barrier is exemplified as a door.

Door locks may take many different forms, including cylinder locks and mortise locks. In some cases, one side of the door lock may always be actuated to allow egress, while the other side may only be selectively actuated to allow ingress. It may be advantageous to notify the occupant that the door lock remains in the locked state, limiting entry. It may also be advantageous to notify those who wish to gain access that the door is locked, restricting access. For example, the lock may employ an "enter" or "intruder" function, wherein a key is required to actuate the lock from a locked state to an unlocked state to allow entry. Such locks are used for example for classroom protection. In the case of a lock, it is advantageous to let the person in the classroom know that the lock has been properly actuated to a locked state that restricts access to the classroom. Other exemplary locks include those that employ a "privacy" function, where release of the lock (i.e., an input that actuates the lock from a locked state to an unlocked state to allow entry) may be actuated, for example, by rotating a slotted input, such as with a flat screwdriver or a coin. Such a lock may be used for security purposes such as in a bathroom. For locks using privacy functions, it may be advantageous to signal to a potential entrant that the facility is occupied.

Detailed Description

For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiments illustrated in the drawings and described below. The embodiments disclosed herein are not intended to be exhaustive or to limit the disclosure to the precise forms disclosed in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in the art may utilize their teachings. Accordingly, there is no intent to limit the scope of the disclosure thereby. Corresponding reference characters indicate corresponding parts throughout the several views.

The terms "coupled," "coupler," and variations thereof may be used to encompass arrangements in which two or more components are in direct physical contact, as well as arrangements in which two or more components are not in direct contact with each other (e.g., "coupled" via at least one third component), but yet still cooperate or interact with each other.

Throughout the present disclosure and in certain instances in the claims, numerical terms such as first, second, third, and fourth may be used to refer to various components or features. These uses are not intended to indicate a sequence of parts or features. Rather, the numerical terms are used to aid the reader in identifying the referenced components or features, and should not be construed narrowly as providing a particular sequence of components or features.

Fig. 1 shows an entry function door lock 30. As shown, the entry function door lock 30 is illustrated as a cylinder lock. Cylinder locks are well known in the art. Accordingly, in the following description, only certain details of an exemplary lock are described in detail, with the detailed description instead focusing on the indicator device and associated method of use.

As shown in fig. 1, the ingress-function door lock 30 includes an egress actuator, exemplified as an egress handle 32. The entry function door lock 30 also includes an entry actuator, exemplified as an entry handle 34. The entry function door lock 30 is operatively coupled to the door 36. In use, the door 36 is arranged to selectively allow and disallow ingress and egress from the area selectively covered by the door 36. In one example, the door 36 may be hinged to a doorframe and may be selectively secured to the doorframe by a latch bolt 38, as is known in the art. In the unlocked state of the entry-function door lock 30, both the egress handle 32 and the ingress handle 34 may be actuated by an operator input action to move the latch bolt 38 from the extended position shown in fig. 1 to the retracted position, allowing ingress and egress through the door 36. When one of the egress handle 32 and the ingress handle 34 is actuated to move the latch bolt 38 to the retracted position, the door 36 is movable relative to its door frame to allow ingress and egress through the door 36.

The entry function door lock 30 includes an internal lock input, illustrated as a lock button 40. The lock button 40 is normally biased to an extended position such as shown in fig. 1 and 17 by a compression spring 42 (fig. 20). This extended position of the lock button 40 corresponds to an unlocked state of the entry function door lock 30. In this unlocked state, the entry handle 34 may receive an operator input motion to rotate the entry handle 34 to actuate the latch bolt 38 from its extended position to its retracted position. Mechanisms for converting rotation of the entry handle 34 (and the exit handle 32) into reciprocal motion of the latch bolt 38 are well known in the art and are not described herein for the sake of brevity. In its simplest form, such a mechanism may take the form of a cam that is rotated by either the entry handle 34 (if the lock is in its unlocked state) or the exit handle 32 to reciprocate the latch bolt 38 between its extended and retracted positions. The user may depress the lock button 40 to the locked position shown in fig. 18 to place the entry function door lock 30 in a locked state in which the entry handle 34 is prevented from rotating; and thus, prevents access through the door 36 via the access handle.

The lock button 40 can be actuated from the depressed locked position shown in fig. 18 to an extended unlocked position such as shown in fig. 1 and 17 in a variety of ways, including by actuating the egress handle 32 to retract the latch bolt 38, and by rotation of the external lock input. In the case of an entry into the functional door lock 30, the external lock input is typically in the form of a key lock device, such as a small form-factor interchangeable key cylinder (SFIC). The external lock input may be keyed to a physical key or an electronic key. In any case, a special input (i.e., a key) is required to actuate the lock button 40 with the external lock input and, thus, the entry function door lock 30 from the locked state to the unlocked state. In many embodiments, the external lock input simultaneously retracts the latch bolt when it is used to place the lock in the unlocked state. In the case of the privacy function door lock 60, the external lock input takes the form of the unlock button 46. The unlock button 46 is not reciprocatable in use, but is rotatable to actuate the lock button 40 to actuate the privacy function door lock 60 from the locked state to the unlocked state. The unlock button 46 includes an externally accessible slot into which a tool, such as a flat screwdriver or a coin, may be inserted to allow a user to rotate the unlock button 46.

The access function door lock 30 and the privacy function door lock 60 are almost identical in construction and operation, except for the external lock input (described above). Throughout this disclosure, the shared elements of the two embodiments and their environments of use are identified by the same reference numerals, even though they belong to different embodiments.

Referring to fig. 20, the lock button 40 is secured to the button rod 44 such that reciprocating movement of the lock button 40 from its extended position (fig. 17) to its retracted position (fig. 18) similarly causes reciprocating movement of the button rod 44 along its longitudinal axis 52 (fig. 15). The button lever 44 is also fixed for reciprocal movement along its longitudinal axis by a locking lug 48. More specifically, locking lug 48 is fixed to locking lug carrier 50 in translation relative to longitudinal axis 52 (fig. 15), and locking lug carrier 50 is fixed for translation along longitudinal axis 52 with button stem 44. When lock button 40 is depressed from its extended position (fig. 17) to its retracted position (fig. 18), lock lugs 48 move a similar distance along longitudinal axis 52.

Referring generally to FIGS. 7-9, 14-16, and 20, the locking lug carrier 50 carries a transverse pin 54, which transverse pin 54 rides in a slot 56 of a sleeve 58. The sleeve 58 includes an end wall against which the compression spring 62 bears. The compression spring 62 also abuts the locking lug carrier 50, biasing the locking button 40 to its extended position (fig. 17). When the locking button 40 is depressed from its extended position to its retracted position (fig. 18), the compression spring 62 is compressed between the end wall of the sleeve 58 and the locking lug carrier 50. During this movement, locking lug 48 translates along longitudinal axis 52 within slot 64 of lever sleeve 66. Locking lug 48 engages slot 64 throughout its range of motion in longitudinal axis 52.

The hub 68 (see, e.g., fig. 7 and 20) is rotationally and translationally fixed to the door 36 (fig. 2) relative to the longitudinal axis 52. When the locking lug 48 is positioned corresponding to the extension of the lock button 40 (fig. 17), the locking lug 48 is free to rotate within the radiused groove 70 (fig. 7) of the hub 68. When the locking lug 48 is axially translated along the longitudinal axis 52 to a position corresponding to the withdrawal of the locking button 40 (fig. 18), it moves axially out of the arcuate groove 70 and instead engages the wall defining the longitudinal slot 72 (fig. 20). In this position (corresponding to retraction of lock button 40), locking lugs 48 are restrained against rotation by walls in hub 68 forming longitudinal slots 72. In this position, locking lug 48 is similarly restrained against rotation relative to control sleeve 66. The control sleeve 66 is constrained from rotating with the entry handle 34, and thus, in this position of the locking lug 48, the entry handle 34 is blocked from receiving sufficient user input to actuate the latch bolt 38.

The button lever 44 includes a locking slot 74, as shown, for example, in fig. 15, 16 and 20. When the lock button 40 is depressed from its extended position (fig. 17) to its retracted position (fig. 18), the catch 76 (biased into engagement with the button stem 44 by the compression spring 78) slides along the flat 80, over the ramp 82, into engagement with the locking slot 74, as shown in fig. 20. In an alternative arrangement shown in fig. 20A and 20B, the catch 76a includes two engagement structures that are engageable in a cooperating pair of locking slots in the button stem 44. When the catch 76 (or 76a) is engaged with the button lever 44, the lock (entry function door lock 30 or privacy function door lock 60) maintains its locked state. The exterior lock input (the keyed device of the entry function door lock 30, or the unlock button 46 of the privacy function door lock 60) or the egress handle 32 may be actuated in a conventional manner to translate the catch 76 against the biasing force of the compression spring 78 and disengage it from the locking slot 74 of the button bar 44. The release cam 84 may be actuated by an external lock input (the unlock button 46 of the belt lock device of the entry function door lock 30 or the privacy function door lock 60) to effect translation of the catch 76, for example, against the biasing force of the compression spring 78. When the catch 76 exits the locking slot 74, the compression spring 62 and the compression spring 42 cooperate to bias the lock button 40 and the button rod 44 (and any other components axially fixed thereto) back to the extended position of the lock button 40, which corresponds to the unlocked state of the lock (into the functional door lock 30 or the privacy functional door lock 60).

With reference to fig. 3-6, 10-13, 17-19 and 22, the lock indicator of the present disclosure will now be described. The transverse bore through the door 36, on which the cylinder locks 30, 60 are mounted, is covered on the inside and outside by a box cover 86 which is fixed relative to the door 36. In the present disclosure, the box cover 86 is used to display an indicator showing the locked or unlocked state of the lock 30, 60 secured thereto. In the case of the entry function door lock 30, the indicator is visible inside the lock, i.e. from the box cover 86 associated with the exit handle 32. In the case of the privacy function door lock 60, the indicator is visible on the exterior of the lock, i.e., from the cover 86 associated with the access handle 34. Although the present disclosure exemplifies an indicator on one of the inner and outer sides, both the inner and outer status indicators may be used with the same lock, if desired.

Figures 4-6, 10, 11, 17 and 18 show the components of the entry function door lock 30. Referring to fig. 4 and 11, the magnet holder 88 is axially fixed to the button stem 44, i.e., the magnet holder 88 moves with the button stem 44 along the longitudinal axis 52 (fig. 4). The magnet holder 88 carries a magnet 90 (fig. 13), the magnet 90 to be used to actuate the status indicator of the present disclosure, as further described below. The button lever 44 is free to rotate relative to the magnet holder 88 so that the locking button 40 (and button lever 44 therewith) can be rotated 90 degrees to maintain the locked state, as is conventional in the art. Referring to fig. 17 and 18, the sleeve 92 includes a slot 94, and the magnet holder 88 is positioned in the slot 94. The slot maintains the rotational position of the magnet holder 88 about the longitudinal axis 52.

Referring to, for example, fig. 4, the lens 96 is secured to the cassette lid 86 and the window 98 protrudes through a window aperture 100. An adhesive may be used to achieve this fixation. In the case of fixing the lens 96 to the case cover 86, the indicator 104 may be fixed thereto in the axial direction using the holding portion 102. The indicator 104 includes an annular groove 106, and the retaining portion 102 is insertable between stops 108 within the annular groove 106. To insert the retaining portion 102 into the annular groove 106, the outer ring 110 displaces the retaining portion radially inward as it rides up the sloped surface on the distal end of the retaining portion 102. After these inclined surfaces disengage the outer ring 110, the retention portions 102 spring back (radially outward) to their position prior to being displaced by the outer ring 100. At this time, the indicator 104 is captured between the window 98 and the stop surface 112 of the holder 102 to prevent the indicator 104 from moving axially relative to the lens 96. In this position, the indicator 104 may be rotated relative to the lens 96 within the range of motion defined by the retaining portion 102 and the stop 108.

Indicator 104 includes an indicia 114 corresponding to window 98. Each indicator 114 includes a locked status indicator and an unlocked status indicator, only one of which is visible through window 98 in each rest position of indicator 104, as will be explained further below. The locked and unlocked status indicators of each flag 114 are positioned such that at each rest position of the indicator 104, both windows 98 will display the same status indicator (i.e., locked or unlocked). The lock status indicator may be a graphical indicator and/or a color indicator. Similarly, the unlock status indicator may be a graphical indicator and/or a color indicator. For example, the unlocked status indicator may be a green portion of each indicia 114 and the locked status indicator may be a red portion of each indicia 114.

Rocker 116 is operable to actuate indicator 104 between a locked state indicating lock 30, 60 and an unlocked position. For example, referring to FIG. 10, the rocker 16 is pivotally connected to the base of the lock 30, 60 by a pivot pin 18. With rocker 116 pivotally secured to the lock base and indicator 104 secured to cassette cover 86 by lens 96, yoke 120 may be aligned with pin 122 of rocker 116 to allow cassette cover 86 to be secured relative to door 36, with indicator 114 operatively positioned. The indicator 114 is operably positioned by the pin 122 of the rocker 116 being captured by the yoke 120 of the indicator 104 such that pivoting of the rocker 116 about the pivot pin 18 causes rotation of the indicator 104 about the lens 96.

Fig. 5 and 6 show the operative arrangement of rocker 116 and indicator 104 with the cassette lid 86 removed. Fig. 5 shows indicator 104 in the unlocked indicating position, wherein green field G of indicia 114 is located below window 98 and is visible through window 98. From this position, the rocker 116 may pivot about the pivot pin 18 to the position shown in fig. 6, as will be described further below. This pivoting of rocker 116 causes a responsive rotation of indicator 104. In particular, with the pin 122 of the rocker 116 captured in the yoke 120 of the indicator 104, displacement of the pin 122 from the position shown in fig. 5 to the position shown in fig. 6 causes the indicator 104 to rotate from the unlocked indicating position shown in fig. 5 to the locked indicating position shown in fig. 6. In the lock indicating position, the red region R of the indicator 114 is located below the window 98 and is visible through the window 98. Rotation of the indicator 104 between the positions shown in fig. 5 and 6 is guided by the cooperation of the outer ring 110 and the stop 108 of the indicator 104 with the retaining portion 102 of the lens 96, as described above.

The rocker 116 carries a magnet 124 (fig. 10), which magnet 124 cooperates with the magnet 90 of the magnet holder 88 to effect movement of the indicator 104 between the locked and unlocked indicating positions shown in fig. 6 and 5, respectively. The magnet 124 is aligned with the magnet 90 such that the magnetic force of the magnets 124, 90 will position the rocker 116 in one of the positions shown in fig. 5 and 6 depending on the position (i.e., extended or retracted) of the lockout button 44. As shown in fig. 17, in the extended position of the lock button 40, the magnet 90 in the magnet holder 88 presents two negative poles adjacent to the rocker 116. Referring to fig. 18, in the retracted position of the lockout button 40, the magnet 90 in the magnet holder 88 exhibits two positive poles believed to be with the rocker 116. The magnet 124 carried by rocker 116 exhibits a radially inward positive magnetic pole and a radially inward negative magnetic pole. With this magnet arrangement, one magnet 124 carried by the rocker 116 is magnetically attracted toward the magnet holder 88, while the other magnet 124 carried by the rocker 116 is magnetically repelled away from the magnet holder 88. Depending on whether the lock button 40 is extended or retracted, the attraction and repulsion are reversed.

The examples of the present disclosure described above rely on the particular arrangement of magnets described above; however, alternative arrangements would also be feasible. For example, the magnets 124 carried by the rockers 116 may present like poles (two positive poles or two negative poles) radially inward and adjacent to the magnet holder 88, in which case the magnet holder 88 would present one positive pole and one negative pole radially outward and adjacent to the rockers 116. The position of the positive and negative poles presented by the magnet holder 88 radially outwardly and adjacent the rocker 116 will be reversed from the position shown in fig. 17 to the position shown in fig. 18. While these alternatives will function to properly indicate the locked state when the egress handle 32 is in the resting state, problems may arise when the egress handle 32 is actuated. This is because rotation of the egress handle 32 causes rotation of the sleeve 92.

Referring to the view of the lock button 40 and subsequently the door 36, the egress handle 32 (and the sleeve 92 therewith) may be rotated clockwise or counterclockwise to actuate the latch bolt 38. If the egress handle 32 (and sleeve 92) is rotated clockwise, the negative magnet on the rocker 116 will rotate away from the associated negative magnet held by the magnet holder 88, while the positive magnet held by the rocker 116 will be positioned adjacent and attracted to the magnetized metal of the steel sleeve 92 that spans the negative magnet of the magnet holder 88, and thus adjacent the second negative magnet held by the magnet holder 88. In this way, the latch bolt 38 will be actuated by actuating the egress handle 32 to maintain the positive magnet attraction force that establishes the rocker 116 position shown in fig. 17. Similarly, if the egress handle 32 (and sleeve 92) is rotated in a counterclockwise direction, the positive magnet on the rocker 116 will rotate away from the associated negative magnet held by the holder 88, while the negative magnet held by the rocker 116 will be positioned adjacent to and repelled by the magnetized metal of the steel sleeve 92 spanning the negative magnet of the magnet holder 88, thereby being adjacent to the second negative magnet held by the magnet holder 88. In this way, the magnetic repulsion force that establishes the rocker 116 position shown in fig. 17 will be maintained by actuating the egress handle to actuate the latch bolt 38.

Fig. 12 and 13 show the magnet holder 88 and the magnet 90 in detail. The magnet holder 88 includes two spaced apart channels, each sized to receive a magnet 90. The pair of magnets 90 received in each channel of the magnet holder 88 will be positioned in a manner where their polarities are opposite to each other to effect actuation of the indicator 104 as described in detail above. As shown in fig. 12, a forged boss 126 may be used to secure the magnet 90 in the magnet holder 88. Alternatively, the magnet 90 may be secured in the magnet holder 88 using an adhesive or a press fit. In an exemplary embodiment of the present disclosure, the magnet holder 88 is a plastic component.

So far, the indicator function of the present disclosure has been described with respect to the entry function door lock 30 (i.e., internal indication of locked/unlocked state by the lock 30). A similar arrangement of components may be used to provide an external indication of the locked/unlocked status of the privacy function door lock 60, for example. Referring to fig. 21, the cassette cover 86 with the aperture 100 is illustrated as an outer cassette cover. The lens 96 and indicator 104 are secured to the cassette cover 86 in the same manner as described above with respect to the entry function door lock 30. As shown in fig. 21, lens 96 includes a projection 99 extending axially from window 98. These projections 99 are placed in the slots 101, interrupting the outer radial ridge of the lock seat fixed to the door 36. The rocker 116 is similarly pivotally supported by a pivot pin 118 fixed to the lock base. On the outside of the lock 30, 60, axial translation of the button stem is translated into axial displacement of the release cam 84, thereby axially constraining the magnet holder 88. In other respects, the indicator assembly functions in the same manner as described above for the entry function door lock 30.

Figures 22-41 illustrate an intruder functional door lock 130. As shown, the intruder-functionality door lock 130 is illustrated as a cylinder lock. As mentioned above, cylinder locks are well known in the art and, therefore, in the following description, only certain details of an exemplary lock will be described in detail, with the detailed description instead focusing on the indicator device and associated method of use.

As shown in fig. 22, the intruder-function door lock 130 includes an egress actuator, exemplified as an egress handle 132. The intruder-functionality door lock 130 also includes an access actuator, exemplified by an access handle 134. The intruder-function door lock 130 is operatively coupled to the door 136. 136 are arranged in use to selectively permit and inhibit ingress and egress from an area selectively covered by the door 136. In an example, the door 136 may be hinged to the doorframe and may be selectively secured to the doorframe by a latch bolt similar to the latch bolt 38 described above and depicted above in fig. 1, 2, 10, and 21. The intruder-function door lock 130 is an intruder lock, meaning that it can be actuated between a locked state and an unlocked state by a key that can be inserted for use through the egress handle 132 and the ingress handle 134. Similar to the entry and privacy locks described above, the egress handle 132 is always in the unlocked state.

In the unlocked state of the intruder functional door lock 130, both the egress handle 132 and the ingress handle 134 can be actuated by an operator input action to move the associated latch bolt from its extended position (see, e.g., FIG. 1, which illustrates the extended latch bolt associated with an alternative cylinder lock (i.e., the ingress functional door lock 30) into a retracted position to allow ingress and egress through the door 136. when one of the egress handle 132 and the ingress handle 134 is actuated to move the associated latch bolt into the retracted position, the door 136 can be moved relative to its door frame to allow ingress and egress through the door 136. mechanisms for converting rotation of the ingress handle 134 (and the egress handle 132) into reciprocal motion of the latch bolt are well known in the art and are not described herein for the sake of brevity. The cam is rotated by either the entry handle 134 (if the lock is in its unlocked state) or the exit handle 132 to reciprocate the associated latch bolt between its extended and retracted positions.

The intruder-function door lock 130 includes a keyed internal lock input and a keyed external lock input (otherwise referred to as an outgoing lock and an incoming lock, respectively), which may each be exemplified as a small form-factor interchangeable key cylinder (SFIC). Both the internal lock input and the external lock input may be keyed to a physical key or an electronic key. In any event, a dedicated input (i.e., a key) is required to utilize the internal and/or external lock inputs to actuate the aggressor functional door lock 130 between its locked state (in which the entry handle 134 is prevented from receiving operator input motion to move its associated latch bolt) and its unlocked state (in which the entry handle 134 is capable of transmitting operator input motion to the reciprocal motion of its associated latch bolt). As described above, mechanisms for converting rotation of an entry handle and/or an exit handle into reciprocating motion of a latch bolt are well known in the art and are not described herein for the sake of brevity. In its simplest form, such a mechanism may take the form of a cam that is rotated by either the entry handle 134 (if the lock is in its unlocked state) or the exit handle 132 to reciprocate its associated latch bolt between its extended and retracted positions.

The SFICs may be placed in keyholes 138, 140 in the egress handle 132 and the ingress handle 134, respectively, to receive key inputs to actuate the intruder-functionality door lock 130, as explained further below. The internal and external lock inputs of the intruder-function door lock 130 may be keyed to a physical key or an electronic key. In any case, a dedicated input (i.e., a key) is required to actuate the intruder-functioning door lock from the locked condition to the unlocked condition using the lock input. Whatever form the input of the lock associated with the egress handle 132 and the ingress handle 134 is formed, the throw member (throw member) will form the output of such a lock.

On the egress side of the intruder-functioning door lock 130, an egress throwing member will extend from the lock inserted into the lock hole 138 and engaged with the slot 142 in the key cam 144 (see, e.g., fig. 22-26, 34 and 36). On the entry side of the intruder-functioning door lock 130, the entry throwing member will extend from the lock inserted into the lock hole 140 and engaged in the slot 146 of the cam 148 (see, e.g., fig. 22, 23, 32 and 33). The throwing member (and associated lock) will hold the key cam 144 and cam 148 against rotation (except for a small amount of rotation due to tolerances between the throwing member and the slot). Rotation of the throwing member by its associated lock will cause rotation of the key cam 144 and cam 148, but additionally the key cam 144 and cam 148 will be substantially retained against rotation.

Actuation of the lock on the entry side of the intruder-functioning door lock 130 will cause rotation of the throwing member positioned in the cam 148, thereby causing rotation of the cam 148. The cam 148 is positioned in the entry function door lock 30 such that it cannot be axially displaced (i.e., displaceable along the longitudinal axis L shown in fig. 23). As shown in fig. 22 and 23, a key release bushing 150 is located within the cam 148. A spring 152 is interposed between the key release bushing 150 and the cam 148. A guide pin 154 is secured to the key release bushing 150 and extends radially outwardly therefrom (relative to the longitudinal axis L, as shown in fig. 23) and into a helical slot 156 (fig. 23). The locking lugs 158 are fixed for axial translation along the longitudinal axis L, but are rotatable relative thereto, with the key release bushing 150. Relative rotation between the cam 148 and a key release bushing 150 (described further below) causes axial translation of the key release bushing. The locking lugs 158 are prevented from rotating and; thus, translation of key release bushing 150 (either by rotation of cam 148 or by rotation of key release bushing 150, as described further below) results in axial translation of locking lug 158 between the unlocked position shown in fig. 23, 29 and 32 and the locked position in fig. 23. The locking lug 158 cooperates with a hub 160 (see, e.g., fig. 22, 23, and 29) and a control sleeve 162 (fig. 22, 23, 29, and 31-33) to selectively prevent user input into the handle 134 from being able to actuate the latch bolt to allow opening of the door 136.

The hub 160 is fixed to the door 136 in a rotational direction and in a translational direction relative to the longitudinal axis L. When the locking lugs 158 are in the unlocked position shown in fig. 23, 29 and 32, the locking lugs 158 are free to rotate within the arcuate recesses 164 (fig. 29) of the hub 160. When locking lugs 158 are axially translated along longitudinal axis L to the locked position shown in fig. 33, locking lugs 158 are axially displaced out of arcuate recesses 164 and are constrained against rotation about longitudinal axis L by the walls of hub 160. In the locked position, the locking lug 158 is similarly restrained from rotating relative to the control sleeve 66. The control sleeve 66 is constrained to rotate with the entry knob 134 and, thus, in the locked position of the locking lug 158, the entry knob 134 is prevented from receiving a user input sufficient to actuate the latch bolt.

The key release bushing 150 is fixed to the locking bushing rod 166 in a rotational direction and in a translational direction. As shown in fig. 27 and 28, the entry coupling end 168 of the locking bushing rod 166 has a geometry that allows the locking bushing rod 166 to snap fit with the key release bushing 150. Structurally, the locking bushing rod 166 is inserted into the key release bushing 150, with the beveled distal ends 170 flexing toward each other until the key release bushing 150 is axially captured between the locking head 172 and the shoulder 174 of the locking bushing rod 166. The key release bushing 150 has an internal flat 184 (fig. 31) that cooperates with the flat 176 at the entry connection end 168 to rotationally lock the key release bushing 150 to the locking bushing rod when assembled, such as shown in fig. 23.

Referring to, for example, fig. 23 and 26, the egress connection end 178 of the locking bushing rod 166 includes a longitudinal bore 180, and the rod 182 of the key cam 144 is structurally inserted into the longitudinal bore 180. With the lever 182 in the longitudinal hole 180, the guide pin 185 is inserted through the peripheral groove 187 and fixed to the lever 182 of the key cam 144. More specifically, the magnet retainer 188 is interposed between the key cam 144 and the egress connection end 178 of the locking bushing rod 166, as shown in fig. 35 and 36. The function of the magnet holder 188 is similar to that of the magnet holder 88 described above. The operation of the magnet holder 188 in the intruder-functional door lock 130 will be further described below.

With the guide pin 185 inserted through the peripheral groove 187 and secured to the stem 182 of the key cam 144, the key cam 144 is secured for translation (along the longitudinal axis L) with the locking bushing rod 166. However, in this position, the key cam 144 may rotate relative to the lock bush rod 166 through an arc of travel defined by the peripheral groove 187. This circular arc stroke will allow a degree of lost motion which facilitates the working of the incoming and outgoing locks in coordination. The peripheral groove 187 is not shown to scale and will be sized to allow for proper functioning of the ingress and egress locks, as further described herein.

When the intruder-function door lock is locked on the entry side (the lock being located in the lock aperture 140 of the entry handle 134), the key cam 144 is held stationary by an outgoing throwing member located in the slot 142 of the key cam 144, while the incoming throwing member is actuated by the entry lock to rotate the cam 148. During rotation of the entry throwing member to rotate the cam 148 to effect locking of the intruder functioning door lock 130, the guide pin 185 (held stationary by the exit throwing member) also holds the locking bush rod 166 (and thus, the key release bush 150) against rotation so that rotation of the cam 148 effects axial displacement of the key release bush 150 and thus the locking lug 158, as described above. During rotation of the cam 148, axial displacement of the key release bushing 150 caused as the guide pin 154 rides along the helical slot 156 of the cam 148 also causes axial displacement of the key cam 144 on the egress side of the intruder-functioning door lock 130. The slot 142 of the outgoing slinger member and the key cam 144 is sized such that the outgoing slinger member remains positioned in the slot 142 to connect the outgoing slinger member and the key cam 144 in the rotational direction during the entire axial stroke of the key release bushing 150 between the locked and unlocked positions of the locking lugs 158.

When the intruder-function door lock 130 is locked on the egress side (the lock being located in the lock hole 138 of the egress handle 132), the cam 148 is held stationary by the ingress throwing member located in the slot 146, while the egress throwing member is actuated by the egress lock to rotate the key cam 144. In the process of the egress throwing member rotating the key cam 144 to effect locking of the intruder-functioning door lock 130, the guide pin 185 is positioned to translate rotation of the key cam 144 into rotation of the locking bush rod 166. Rotation of the locking bushing rod 166 causes the key release bushing 150 to rotate. With the cam 148 held against rotation by the entry throwing member, rotation of the key release sleeve rides the guide pin 154 along the helical slot 156 of the cam 148 to axially displace the key release sleeve 150 and thus the locking lug 158, as further described herein. Unlocking by the ingress and egress locks is performed in a conventional manner, with a first rotation of each throwing member (ingress and egress) effecting locking of the intruder-functionality door lock 130, and a second rotation of each throwing member opposite the first rotation effecting unlocking of the intruder-functionality door lock 130.

The intruder functional door lock 130 has a lock indicator with shared components with the lock indicators described for the entry functional door lock 30 and the privacy functional door lock 60, and for the intruder functional door lock 130 the shared lock indicator components are designated with similar reference numerals to those used for the entry functional door lock 30, but increased by 100. Unless the document dictates otherwise, the lock indicator of the intruder functional door lock 130 functions in the same manner as the lock indicator of the entry functional door lock 30 and vice versa. For the sake of brevity, all shared structures and functions are not described for all lock indicators disclosed in this document.

Fig. 24 and 34-41 show details of the lock indicator of the intruder-enabled door lock 130. Referring to fig. 24, the transverse bore through the door 136 (in which the cylinder lock 130 is mounted) is covered on the egress and ingress sides by a cassette cover 186, the cassette cover 186 being fixed relative to the door 136. In the present disclosure, the box cover 186 is used to display an indicator of the locked state or unlocked state of the intruder-functioning door lock 130 on the outgoing side of the intruder-functioning door lock 130, i.e., from the box cover 186 associated with the outgoing handle 132. As described above, in the case of the privacy function door lock 60, the indicator is visible on the outside of the lock, i.e., from the box cover 86 associated with the access handle 34. Although the present disclosure illustrates the indicator on one of the inboard and outboard sides (i.e., the egress and ingress sides, respectively), both the inboard and outboard status indicators may be used on the same lock, as desired.

Referring to fig. 24 and 34-36, the magnet holder 188 is axially fixed to the locking bushing rod 166, i.e., the magnet holder 188 moves with the locking bushing rod 166 along the longitudinal axis L. Because the locking bush lever 166 is translated in the axial direction by actuation of the intruder functional door lock 130 between the locked and unlocked positions by both the entry and exit locks of the intruder functional door lock 130, the magnet holder 188 is operable to trigger the lock indicator regardless of which lock is used to establish the locked or unlocked state of the intruder functional door lock 130.

The magnet holder 188 carries a magnet 190, the magnet 190 to be used to actuate the status indicator of the present disclosure. The locking bush lever 166 is free to rotate relative to the magnet holder 188 such that during locking or unlocking triggered at an outgoing lock of the intruder-functional door lock 130, rotation of the bush lever 166 will not be affected or prevented by the rotational position of the magnet 190 about the rotational axis L. Referring to fig. 36, the magnet retainer 188 includes an inward radial projection 189 between the head of the key cam 144 and the outboard connection end 178 of the locking bushing rod 166. When assembled as shown in fig. 35, the head of the key cam 144 is spaced from the egress connection end 178 of the locking bushing rod 166 to allow the magnet holder 188 to rotate relative to both the key cam 144 and the locking bushing rod 166. The magnet holder 188 is held in a rotational position by a sleeve 192 in a similar manner to the sleeve 92 and magnet holder 88 described above.

Referring to, for example, fig. 34, the lens 196 is secured to the cassette cover 186 and the window 198 protrudes through the window aperture 200. An adhesive may be used to achieve this fixation. With the lens 196 secured to the cassette cover 186, the retainer 202 may be used to axially secure the indicator 204 thereto. Referring to fig. 39, the indicator 204 includes an annular groove 206, and the retainer 202 may be inserted between stops 208 in the annular groove 206. To insert the retaining portion 202 into the annular groove 206, the outer ring 210 displaces the retaining portion 202 radially inward as it rides over the annular groove 206 at the distal end of the retaining portion 202. After these sloped surfaces disengage the outer ring 110, the retaining portions 202 spring back (radially outward) to their position prior to being displaced by the outer ring 210. At this time, the indicator 204 is captured between the window 198 and the stop surface 212 of the holder 202 to prevent the indicator 204 from moving axially relative to the lens 196. In this position, the indicator 204 may rotate relative to the lens 196 within the range of motion defined by the retaining portion 202 and the stop 208.

Indicator 204 includes an indicia 214 corresponding to window 198. Each indicia 214 includes a locked status indicator and an unlocked status indicator, only one of which is visible through window 198 at each rest position of indicator 204. The locked and unlocked status indicators of each flag 214 are positioned such that at each rest position of indicator 204, both windows 198 will display the same status indicator (i.e., locked or unlocked). The lock status indicator may be a graphical indicator and/or a color indicator. Similarly, the unlock status indicator may be a graphical indicator and/or a color indicator. For example, the unlocked status indicator may be a green portion of each flag 214, and the locked status indicator may be a red portion of each flag 214.

Referring to, for example, fig. 34, rocker 116 is operable to actuate indicator 104 between a locked state indicating locks 30 and 60 and an unlocked position. For example, referring to FIG. 10, the rocker 16 is pivotally connected to the base of the lock 30 by a pivot pin 18. With rocker 116 pivotally secured to the lock base and indicator 104 secured to cassette cover 86 by lens 96, yoke 120 may be aligned with pin 122 of rocker 116 to allow cassette cover 86 to be secured relative to door 36, with indicator 114 operatively positioned. The indicator 114 is operably positioned by the pin 122 of the rocker 116 being captured by the yoke 120 of the indicator 104 such that pivoting of the rocker 116 about the pivot pin 18 causes the indicator 104 to rotate about the lens 96.

Fig. 40 and 41 show the flag 214 in an unlocked position and a locked position, respectively, relative to the window 198. In fig. 40 and 41, the unlock image and the lock pattern are used as the status indicators. As previously mentioned, alternative indicators or signals, such as color or text indicators, may alternatively or additionally be used. In the unlock indicating position of fig. 40, the unlock graphic is located below and visible through the window 98. In the lock indicating position of fig. 41, the lock graphic is positioned below and visible through the window 98.

Indicator 204 is actuated by rocker 216 (see, e.g., fig. 34, 37 and 38) between an unlocked indicator position (fig. 40) and a locked indicator position (fig. 41). Referring to fig. 23 and 34, the rocker 216 is rotatably supported by the hub 217. More specifically, pivot pin 218 is snap fit into a hole 219 in hub 217. When assembled as shown in fig. 23, pin 222 of rocker 216 is captured in yoke 220 of indicator 204 (see, e.g., fig. 34, 40, and 41). Thus, pivoting of the rocker 216 about the longitudinal axis of the pivot pin 218 causes a responsive rotation of the indicator 204 about the longitudinal axis L. The pivot axis defined by the pivot pin 28 intersects the door 136, as does the longitudinal axis L. The pivot axis defined by the pivot pin 28 is spaced from the longitudinal axis L about which the rocker 216 (and the egress handle 132 and the ingress handle 134) rotates. With the pivot pin 218 pivotally connected to the hub 217, the rocker 216 can be actuated between two positions as exemplified with respect to the rocker 116 in fig. 5 and 6 (as will be described later). When indicator 204 displays the unlock graphic (fig. 40) through window 198, rocker 216 will occupy a first pivot position (fig. 5), and when indicator 204 displays the lock graphic (fig. 41) through window 198, rocker 216 will occupy a second pivot position (fig. 6) different from the first position. The first and second pivot positions of rocker 216 are the same as the pivot positions of rocker 116 described above and therefore will not be described again to avoid unnecessary repetition.

The rocker 216 carries a magnet 224 (fig. 24), which magnet 224 cooperates with the magnet 190 of the magnet holder 188 to effect movement of the indicator 204 between the unlocked and locked indicating positions shown in fig. 40 and 41, respectively. The magnet 224 is aligned with the magnet 190 such that the magnetic force of the magnets 224, 190 positions the rocker 216 in one of the positions shown relative to the rocker 116 in fig. 5 and 6, depending on whether the intruder-functionality door lock 130 is held in the locked or latched state as described herein. The magnets 190 of the magnet holder 188 function in the same manner as the magnets 90 of the magnet holder 88 described above. Similar to the magnet 90 shown in fig. 17, in the unlocked position of the locking bushing rod 166 (and locking lug 158) described above, the magnet 190 in the magnet holder 188 has two negative poles adjacent to the rocker 216. Similar to the magnet 90 shown in fig. 18, in the unlocked position of the above-described locking bushing rod 166 (and locking lug 158), the magnet 190 in the magnet holder 188 exhibits two positive poles adjacent to the rocker 216. Rocker 216 carries a magnet 224 having a radially inward positive pole and a radially inward negative pole. With this magnet arrangement, one magnet 224 carried by the rocker 216 is magnetically attracted toward the magnet holder 188, while the other magnet 224 carried by the rocker 216 is magnetically repelled away from the magnet holder 188. The attraction and repulsion are reversed depending on whether the door lock 130 is locked or unlocked by the intruder function. The magnetic force holding the rocker 216 (or the rocker 116) in a first position may be collectively or individually referred to as a first magnetic force, while the magnetic force holding the rocker 216 (or 116) in a second position different from the first position may be collectively or individually referred to as a second magnetic force.

As with the previously described embodiments, alternative magnet arrangements will also provide the desired functionality. For example, the magnet 224 carried by the rocker 216 may present like poles (two positive poles, or two negative poles) radially inward and adjacent to the magnet holder 188, in which case the magnet holder 188 would present one positive pole and one negative pole radially outward adjacent to the rocker 216. The position of the positive and negative poles presented radially outwardly by the magnet holder 188 and adjacent to the rocker 216 will reverse from the position shown in fig. 17 relative to the magnet holder 88 to the position shown in fig. 18 relative to the magnet holder 88. While these alternatives will function to normally display the locked state when the egress handle 132 is at rest, problems may arise when the egress handle 132 is actuated. This is because rotation of the egress handle 132 causes rotation of the sleeve 192.

When the intruder-enabled door lock 130 is held in its unlocked state, the egress handle 132 (and its sleeve 192) may be rotated clockwise or counterclockwise to actuate the latch bolt of the intruder-enabled door lock 130. If the egress handle 132 (and sleeve 192) is rotated clockwise, the negative magnets on rocker 216 will no longer be positioned to be repelled by one of the negative magnets held by magnet holder 188 (see FIG. 17); however, the negative magnet of the magnet holder 188 will be positioned to attract the positive magnet held by the magnet holder 188. In this manner, actuating the latch bolt associated with the intruder-functionality door lock 130 by actuating the egress handle 132 will maintain the positive magnet attraction force establishing the position of the rocker 216. Similarly, if the egress handle 132 (and sleeve 192) is rotated counterclockwise, the positive magnet on the rocker 216 will no longer be positioned to be attracted by one of the negative magnets held by the magnet holder 188; however, the negative magnet of the magnet holder 188 will be positioned to repel the negative magnet held by the magnet holder 188. In this manner, the magnetic repulsion force establishing the position of rocker 216 is maintained by actuating the egress handle to actuate the latch bolt associated with the intruder-function door lock 130.

Advantageously, the lock indicator of the present disclosure is received between the door and the standard size box lid.

Although the internal indication of the locked/unlocked state of the lock is optionally described herein generally by an entry function or an intruder function, and the external indication of the locked/unlocked state of the lock is described generally by a privacy function, it will be understood that both an internal indicator and an external indicator may be provided for any lock. For example, the external indication may be provided with an entry function or an intruder function, and the internal indication may be provided with a privacy function.
