Description

Technical Field

[0001] The present invention relates to latch assemblies and, in particular, to an exit device mountable to a movable barrier for securing the exit device to a structure and, in some embodiments, to a pad actuation device for releasing a striker. Background Art

[0002] Exit devices are commonly used on doors in public environments, where a push rod (i.e., actuator) converts a user's push into unlocking of the door latch mechanism, allowing pedestrians to enter or exit. The exit device converts the forward movement of the push rod into lateral movement to withdraw the latch bolt from the striker plate in the unlocked state. The striker plate is typically mounted to a fixed column or frame, where the latch bolt and striker plate are used to secure the free end of the door in the latched state.

[0003] Exit devices are designed and constructed to meet internationally recognized standards, such as BHMA 156.3. For example, under one of the requirements of BHMA 156.3, the maximum force for operating the push rod (i.e., unlocking the latch bolt from the striker plate) is 67N (15lbf). In order to control the unlocking force, door hardware manufacturers have led to the use of a rotatable shaft on the striker plate to engage the latch bolt. In addition, the surface of the latch bolt can be shaped to follow the linear displacement of the latch bolt, so the combination of this surface and the rotatable shaft reduces the friction between the latch bolt and the striker plate. Summary of the invention

[0004] According to a first aspect, an exit device is disclosed for releasably securing a movable barrier to a structure. The movable barrier may be, for example, a gate or door. The structure may be a fixed structure, such as a gate post or frame. The exit device includes a latch assembly configured to cooperate with a striker assembly, the latch assembly including a retainer latch member and a retainer, the retainer latch member cooperating with the retainer, the retainer latch member extending between a first end and a second end and moving between an engaged position and a released position, the retainer including a latch face and a strike face and moving between a first position and a second position, the retainer being retained in the first position when the retainer latch member is in the engaged position.

[0005] That is, when the retainer latch member and the retainer are engaged together, the retainer is retained in the first position.

[0006] In use, when the retainer latch member is in the engaged position, the second end of the retainer latch member engages the latching surface of the retainer to retain the retainer in the first position.

[0007] When the retainer latch member is in the released position, the second end of the retainer latch member disengages from the latching surface of the retainer and the retainer is operable to move to a second position, thereby enabling the movable barrier (i.e., gate) to move to an open position relative to the structure (i.e., gate post).

[0008] In this way, the retainer latch member can engage the retainer in a first position to releasably secure the movable barrier to the structure. When the retainer latch member is disengaged from the retainer, the movable barrier (i.e., the gate) can be moved to the open position.

[0009] In some forms, the strike block assembly includes a strike block bolt that is capable of moving between an extended position and a retracted position so that when the strike block assembly is aligned with the latch assembly, the strike block bolt moves to the extended position to engage with the latch assembly. In use, when the retainer latch member is in the engaged position, the second end of the retainer latch member can engage the latch surface of the retainer to hold the retainer in the first position so that the strike block bolt can be maintained in the extended position.

[0010] The retainer latch member engages the retainer such that the retainer cannot move to the second (disengaged) position, thereby preventing the striker bolt from disengaging from the latch assembly.

[0011] When the keeper latch member is in the release position, the second end of the keeper latch member can be disengaged from the latching surface of the keeper, so that the striker bolt engages the striker surface of the keeper to move the keeper to the second position, thereby enabling the movable barrier to move to the open position. When the keeper is disengaged from the keeper latch member, the keeper can be moved by the striker bolt so that the movable barrier, i.e., the gate, can be opened.

[0012] In some forms, the exit device further includes an actuator assembly including an actuator movable between a raised position and a depressed position. When in the depressed position, the actuator assembly actuates the latch assembly by engaging the first end of the retainer latch member to move it to the released position, thereby allowing the striker bolt to move the retainer to the second position while simultaneously moving the movable barrier toward the open position.

[0013] That is, when the actuator is depressed, the actuator assembly is used to move the retainer latch member to the release position. This allows the striker bolt to move the retainer to the second position, whereby the movable barrier is free to move toward the open position.

[0014] According to a second aspect, a passage device is disclosed, comprising an exit device as described above, the passage device further comprising a remote actuator for allowing the exit device to be operated from a remote side (i.e. the other side) of a movable barrier. The remote actuator is operable to move the retainer latch member between the engaged position and the released position. Advantageously, the remote actuator provides an alternative mechanism for moving the retainer latch member to the released position (i.e. for allowing the movable barrier to open).

[0015] In some forms, the remote actuator is operable to enable the retainer to remain in the first position, or is operable to enable the retainer to move from the first position to the second position via the striker bolt while simultaneously moving the movable barrier toward the open position.

[0016] In other words, the remote actuator may be used to keep the movable barrier closed, ie, to hold the retainer in the first position, or to allow the movable barrier to open, ie, to allow the retainer to move from the first position to the second position.

[0017] According to a second aspect, a latch device is disclosed for an exit rod assembly, the latch device being configured to be mounted to a movable barrier and a structure. The latch device is configured to releasably secure the movable barrier to the structure. The latch device includes a striker assembly configured to cooperate with the latch assembly. The striker assembly includes a striker bolt and a striker bolt housing, the striker bolt housing accommodating at least a portion of the striker bolt. The striker bolt is movable between an extended position and a retracted position. When the striker assembly and the latch assembly are aligned, the striker bolt extends from the striker bolt housing to the extended position. When the striker assembly and the latch assembly are not aligned, the striker bolt retracts into the striker bolt housing to the retracted position.

[0018] Advantageously, when the striker bolt is retracted into the striker bolt housing, the striker assembly can freely move past the latch assembly so that the movable barrier does not contact the latch assembly. In turn, this allows the movable barrier to freely move to a position where the striker assembly and the latch assembly are aligned.

[0019] The latch assembly is operable to retain the striker bolt in the extended position. The latch assembly includes a retainer having a latch face and a strike face. The retainer is movable between a first position and a second position. When the retainer is in the first position, the strike face is engageable with the striker bolt to retain the striker bolt in the extended position. That is, the first position of the retainer prevents the striker assembly from moving away from alignment with the latch assembly (whereby the striker bolt can be retracted into the striker bolt housing).

[0020] In use, when the latch device is actuated, the striker bolt engages the striker surface to move the retainer to the second position. The striker bolt is allowed to move to the retracted position when the striker bolt is misaligned or substantially misaligned with the latch assembly.

[0021] That is, when the latch arrangement is actuated, the retainer is movable to the second position whereby the striker bolt moves away from alignment with the latch assembly.

[0022] In some forms, the retainer assembly may be configured to be mounted to the structure and the latch assembly may be configured to be mounted to the movable barrier.

[0023] In some forms, a retainer of the latch assembly may be rotatable between a first position and a second position.

[0024] In some forms, the latch assembly may further include a retainer latch member. The retainer latch member extends between a first end and a second end. The retainer latch member can rotate between an engaged position and a released position, such that when the retainer latch member is in the engaged position, the second end of the retainer latch member can engage the latching surface of the retainer to retain the retainer in the first position and retain the striker bolt in the extended position.

[0025] The retainer latch member can cooperate with the retainer so that when the retainer is in the first position, the retainer engages with the retainer latch member so that the retainer cannot rotate from the first position. This prevents the striker bolt from rotating the retainer to the second position (whereby the movable barrier can be moved to the open position).

[0026] Advantageously, maintaining the striker bolt in the extended position when the striker bolt is aligned with the latch assembly ensures that the striker bolt will engage the striker surface of the retainer unless the retainer is in the second position.

[0027] In some forms, the retainer latch member further comprises a rotatable member disposed at the second end. The rotatable member can engage the latching surface of the retainer in the engaged position. Advantageously, when the retainer latch member is rotated between the engaged position and the released position, the rotatable member can rotate relative to the latching surface so as to minimize resistance between the retainer and the retainer latch member.

[0028] In some forms, the latch assembly further includes a second frame extending between the second frame first end and the second frame second end. The second frame is movable between an applied position and a neutral position. When the second frame is in the applied position, the second frame moves the retainer latch member to the released position. That is, when the second frame moves from the neutral position to the applied position, the second frame moves the retainer latch member to the released position.

[0029] In some forms, the second bracket is slidable between an active position and a neutral position.

[0030] In some forms, the second bracket includes an abutment surface that abuts the first end of the retainer latch member to move, ie, rotate, the retainer latch member to the release position when the second bracket is moved to the active position.

[0031] In some forms, the latch assembly further comprises a biasing member that biases the retainer to the first position. The biasing member may be a torsion spring. In this way, when the retainer latch member is in the released position, i.e., when the retainer latch member is not engaged with the retainer, the retainer will move to the first position.

[0032] In some forms, the retainer latch member further comprises a biasing member that biases the retainer latch member to the engaged position. The biasing member may be a torsion spring. In this way, when the second frame is not in the active position, for example when the second frame is moved to the neutral position, the retainer latch member will move to the engaged position.

[0033] In some forms, the striker assembly includes a biasing device adapted to urge the striker bolt toward the retracted position. In this way, the striker assembly does not interfere with the latch assembly when the latch assembly moves toward alignment with the striker assembly.

[0034] In some forms, the latch assembly further comprises a magnet. The striker bolt may be attracted to the magnet such that when the latch assembly and the retainer assembly are aligned, a magnetic force between the magnet and the striker bolt causes the striker bolt to move to the extended position. The latch assembly may hold the striker bolt in the extended position such that the latch device is in the latched position. That is, when the retainer is held in the second position, i.e., engaged with the retainer latch member, the striker bolt extended by the magnetic force (i.e., held extended by the magnetic force) is held in the latched position by the retainer.

[0035] In some forms, the magnet is adapted such that the magnetic force is greater than the biasing force generated by the biasing device so that when the latch assembly and the striker assembly are aligned, the striker bolt moves toward the extended position.

[0036] In some forms, the latch assembly includes a recess for receiving the striker bolt in the extended position, and the recess may be partially defined by the striker surface of the retainer.

[0037] In some forms, the recess may be juxtaposed or axially aligned with the magnet.

[0038] In some forms, the striker assembly includes a striker body having an inner surface that defines an inner cavity for receiving the striker bolt assembly. The striker bolt assembly may also include a striker bolt housing configured to be coaxial with the striker bolt and configured to receive the striker bolt in the retracted position. That is, the striker bolt housing may be sized, for example, to receive the striker bolt in the retracted position.

[0039] At least a portion of the outer surface of the striker bolt housing may be threaded so as to engage in a threaded engagement to allow the striker bolt assembly to be adjustable to a selected position relative to the striker body, thereby allowing the striker assembly and the latch assembly to be aligned in a latching engagement when the striker bolt is in the extended position.

[0040] That is, the threaded cooperation of the striker bolt assembly and the striker body allows the striker bolt to be moved to a selected or optimal position whereby the striker assembly and the latch assembly are aligned when the striker bolt is in the extended position, ie, when the movable barrier is closed.

[0041] In some forms, the latch device may also include a lock assembly including a locking member located in the inner cavity of the striker body. The locking member may be movable between a locked position and an unlocked position. When the locking member is in the locked position, the locking member may engage the striker bolt housing to hold the striker bolt housing in a selected position. That is, once the striker bolt assembly and the striker body are aligned (by moving the striker bolt to, for example, an optimal alignment position), the locking member may be moved to engage and hold the striker bolt housing.

[0042] When the locking member is in the unlocked position, the striker bolt housing can be adjusted to another selected position. That is, the locking member can be unlocked to allow the striker bolt housing to be readjusted in place, for example, relative to the striker main body.

[0043] In some forms, the locking member extends longitudinally between a first end and a second end. The first end may include an inclined surface. The inclined surface may be configured to cooperate with a corresponding inclined surface formed as part of the inner surface of the striker body. The inclined surface and the corresponding inclined surface may guide the locking member to a locked position and an unlocked position. The second end may include an engagement surface for engaging an abutment surface of the striker bolt housing in the locked position.

[0044] In some forms, the lock assembly may also include an externally threaded actuator, such as a screw, for moving the locking member relative to the striker bolt housing to a locked position and an unlocked position. The locking member may include an internally threaded channel for receiving the externally threaded actuator. The rotational movement of the actuator is converted into a movement of the locking member in a lateral direction between the locked position and the unlocked position guided by the corresponding inclined surface.

[0045] That is, when the actuator is screwed into the channel, the locking member moves in the lateral direction (between the locked position and the unlocked position) under the guidance of the inclined surface. Advantageously, this can allow the position of the striker bolt housing to be easily adjusted, for example by using a screwdriver to rotationally operate the threaded actuator to move the locking member between the locked position and the unlocked position.

[0046] In some forms, the striker bolt housing extends between a distal end and a proximal end. The distal end may be disposed within the striker body. The proximal end may include a non-circular end region to allow a tool to grasp the end region and rotate the striker bolt housing relative to the striker body to provide adjustment of the striker bolt housing relative to the striker body to another selected position.

[0047] In some forms, the striker bolt housing may include a flange extending at least partially around the proximal end. The non-circular end region may include at least one flat surface formed on the flange. In some forms, two opposing parallel flat surfaces may be formed on the flange so that, for example, a wrench may be fitted to the non-circular end to rotate the striker bolt housing.

[0048] In some forms, the striker assembly may further include an insert disposed in the striker body. That is, the insert is separate from the striker assembly. At least a portion of an outer surface of the striker bolt housing may be formed on the insert, the insert including threads for mating with threads of the striker bolt housing. That is, at least a portion of an outer surface of the striker bolt housing includes threads for mating with the threaded insert.

[0049] The insert may be insertable into the striker body and may be configured to retain the striker bolt housing within the striker bolt housing.

[0050] According to a third aspect, an exit device is disclosed, comprising a latch device as described above, the latch device further comprising an actuator assembly. The actuator assembly comprises an actuator movable between a raised position and a depressed position. When in the depressed position, the actuator assembly actuates the latch assembly by engaging a first end of the retainer latch member to move it to a released position, thereby allowing the striker bolt to move the retainer to the second position while the movable barrier moves toward the open position.

[0051] When depressed, the actuator assembly moves the retainer latch member to a released position so that the movable barrier may move toward the open position.

[0052] In some forms, the actuator assembly may further include an elongated frame extending between a first end and a second end along a longitudinal axis. The actuator may be mounted relative to the elongated frame and depressibly operable relative to the elongated frame transverse to the longitudinal axis of the elongated frame to actuate the latch device.

[0053] The first frame may extend between a first frame first end and a first frame second end in the elongated frame. The first frame may be movable between a driven position and a neutral position. The first frame may include an engagement surface disposed at the first frame second end to drive the retainer latch member to move to a release position when the first frame is in the driven position.

[0054] In some forms, when the first frame is in the driven position, the engagement surface of the first frame can engage the abutment surface of the second frame to move the second frame to the active position of the second frame. When the second frame moves to the active position, the second frame can move the retainer latch member to the release position to allow the retainer to move to the second position while the movable barrier moves toward the open position.

[0055] In some forms, the actuator assembly may further include at least one bell crank pivotally connected to the actuator and the first frame to convert a lateral force transmitted by angular rotation of the bell crank into a force transmitted in the longitudinal direction of the elongated frame toward a joint surface between the second end of the first frame and the second end of the elongated frame through depression of the outlet rod and initial movement of the movable barrier to an open position.

[0056] In the depressed position, the actuator may be positioned close to (eg, against) the first frame. In the raised position, the actuator may be positioned away from, i.e., spaced apart from, the first frame, wherein the raised position is relative to the position of the actuator when in the depressed position.

[0057] In some forms, when the actuator is released, the actuator may be biased to a raised position to cause the first and second frames to move to respective neutral positions, the retainer latch member to rotate to the engaged position, and the retainer to rotate to the first position.

[0058] In some forms, the exit assembly may further include a remote actuator for allowing the latch assembly to be operated from the other side of the movable barrier. The remote actuator may extend between a first remote actuator end and a second remote actuator end. The first remote actuator end may be configured to be connected to a remote drive such that the remote actuator rotates. The second remote actuator end may be connected to the second carriage and may include a cam such that rotation of the remote actuator is converted into movement of the second carriage to an applied position, which causes the retainer latch member to move to a released position.

[0059] According to a fourth aspect, an outlet assembly is disclosed, the outlet assembly being configured to be mountable to a movable barrier and a structure. The outlet assembly may be configured to releasably secure the movable barrier to the structure.

[0060] The outlet assembly includes an actuator device including an actuator movable between a raised position and a depressed position. When in the depressed position, the actuator device allows the movable barrier to move to the open position.

[0061] The exit assembly includes a latch assembly that cooperates with the striker assembly. The striker assembly includes a striker bolt. The latch assembly includes a striker surface for retaining the striker bolt in a latched position when the door is in a closed position. The actuator device can act on the latch assembly to allow the movable barrier to be released and move to an open position. That is, the actuator of the actuator assembly can be moved from a raised position to a depressed position to allow the movable barrier to move to the open position.

[0062] According to a fifth aspect, an exit assembly is disclosed for a movable barrier, the exit assembly comprising an actuator assembly and a latch device. The actuator assembly can be configured to be mounted to an elongated frame extending between a first end and a second end. The actuator device comprises an actuator that can be pressed relative to the elongated frame to actuate (i.e., move) the latch device.

[0063] The latch device includes a latch assembly and a striker assembly. The latch assembly and the striker assembly may be configured to cooperate in a latching engagement. The latch assembly may include a magnet, and the striker assembly may include a striker bolt, which is attracted to the magnet so that when the latch assembly and the striker assembly are aligned, the magnetic force between the magnet and the striker bolt moves the striker bolt to the extended position, and the latch assembly holds the striker bolt so that the latch device is in the latched position.

[0064] The magnetic force of the magnet is used to pull the striker bolt into the extended position, i.e., to move the striker bolt closer to the magnet. In this manner, when the magnet of the latch assembly and the striker bolt of the striker assembly are aligned, the magnetic force is greatest to pull (i.e., extend) the striker bolt. In the extended position, i.e., extended from the striker assembly, the striker bolt is in latching engagement with the latch assembly.

[0065] The actuator assembly and the latch assembly can be mechanically connected and configured such that depression of the actuator and initial movement of the movable barrier can cause the magnet and striker bolt to move into misalignment, which disengages the latch assembly to allow the movable barrier to move to the open position.

[0066] As the striker bolt moves, i.e., from the initial movement of the obstruction away from the closed position (i.e., to the open position), the spacing between the striker bolt and the magnet increases, causing the magnetic force acting on the striker bolt to weaken. This results in the striker bolt no longer being held in the extended position.

[0067] According to a sixth aspect, a striker assembly is disclosed, which is configured to cooperate with a latch assembly of a latch device when used in an outlet assembly. The striker assembly includes a striker body, which includes an inner surface defining an inner cavity. The striker assembly also includes a striker bolt housing and a striker bolt. The inner cavity of the striker body accommodates the striker bolt housing and the striker bolt, and the striker bolt housing and the striker bolt can be configured to be coaxial with each other. The striker bolt can be moved to an extended position so that in the extended position, the striker bolt engages with a component of the latch assembly in a latching engagement manner.

[0068] At least a portion of the outer surface of the striker bolt housing is threaded to cooperate in threaded engagement to allow the striker bolt assembly to be adjustable to a selected position relative to the striker body to facilitate alignment of the striker assembly and the latch assembly in latching engagement. The selected position of the striker bolt assembly can be selected to ensure that the striker bolt engages a component of the latch assembly when the striker bolt is in the extended position.

[0069] In some forms, the striker assembly further includes a lock assembly, the lock assembly including a locking member located in the inner cavity of the striker body. The locking member can move between a locked position and an unlocked position. When the locking member is in the locked position, the locking member can engage the striker bolt housing to maintain the striker bolt housing in a selected position. When the locking member is in the unlocked position, the striker bolt housing can be adjusted to another selected position.

[0070] In some forms, the locking member extends longitudinally between a first end and a second end, the first end includes an inclined surface, the inclined surface is configured to cooperate with a corresponding inclined surface, the corresponding inclined surface forms a part of the inner surface of the housing, the inclined surface and the corresponding inclined surface guide the locking member to the locked position and the unlocked position, and the second end includes an engagement surface, the engagement surface is used to engage the adjacent surface of the block bolt housing in the locked position.

[0071] In some forms, the lock assembly may also include an externally threaded actuator, such as a screw, for moving the locking member relative to the striker bolt housing to a locked position and an unlocked position. The locking member includes an internally threaded channel for receiving the externally threaded actuator. The rotational movement of the actuator can be converted into a lateral movement of the locking member between the locked position and the unlocked position guided by the corresponding inclined surface. The lateral movement can cause the locking member to move into and out of engagement with the striker bolt housing, i.e., between the unlocked position and the locked position.

[0072] In some forms, the striker bolt housing extends between a distal end and a proximal end. The distal end may be disposed within the striker body. The proximal end may include a non-circular end region to allow a tool to grasp the end region and rotate the striker bolt housing relative to the striker body to provide adjustment of the striker bolt housing relative to the striker body to another selected position.

[0073] In some forms, the striker bolt housing may include a flange extending at least partially around the proximal end. The non-circular end region includes at least one flat surface formed on the flange.

[0074] In some forms, the striker assembly may further include an insert disposed in the striker body. At least a portion of an outer surface of the striker bolt housing may be formed on the insert, the insert including threads for mating with threads of the striker bolt housing.

[0102] It should be understood that unless otherwise specified, the structure may include a movable barrier, gate, door, fence, frame, panel, post, or any other suitable structure for mounting a latch assembly.

[0103] It should be understood that the terms bracket and fixture are intended to have their literal meanings unless otherwise stated.

[0104] It should be understood that unless otherwise stated, the term mounted includes temporarily fastened, attached, removably fastened and secured, and that the term is intended to describe a component placed on another component or body and is not limited to the type of securing device used or whether the securing device is permanent or temporary.

[0105] It should be understood that, unless otherwise specified, the term movable barrier includes, for example, structures, hatches, gates, doors, skylights or windows, i.e., components adapted to close or open an aperture, but not limited to a pivoting or moving direction. For example, the component may pivot or slide horizontally and / or vertically.

[0106] It should be understood that the terms alignment and / or alignment are not limited to coaxial alignment, horizontal alignment, vertical alignment, planar alignment, etc., unless otherwise specified.

[0107] Although the following detailed description discloses that the striker is mounted on a structure in the form of a post and the latch assembly is mounted on a structure in the form of a door, in alternative embodiments this may be reversed, ie, the latch assembly may be mounted on the post and the striker may be mounted on the door.

[0108] It should be understood that, unless otherwise stated, the term exit means allowing passage from one area to another area, wherein a boundary or perimeter partition is provided between the two areas. Unless otherwise stated, one area may be a restricted / controlled area and another area may be an unrestricted / uncontrolled area.

[0109] It will be understood that, unless otherwise stated, the term passage means refers to means that allow passage between two areas, wherein a boundary or perimeter partition is provided between the two areas.

[0110] Embodiments of the exit devices disclosed herein facilitate evacuation through a movable barrier. In some cases, rapid evacuation is required. In some embodiments of the exit devices disclosed herein, the embodiments of the exit devices are configured to allow evacuation without requiring a large amount of force on the actuator assembly to unlock the latch mechanism while providing a secure and reliable latch arrangement in the closed position.

[0111] refer to Figure 1 , shows an exit device, namely an exit rod assembly 50, including an actuator assembly 100 and a latch assembly 60. The latch assembly 60 includes a latch assembly 200 and a striker assembly 300. The actuator assembly 100 and the latch assembly 200 are suitable for installation on a movable barrier, such as a gate or door, and the striker assembly 300 is suitable for installation on a fixed or fixable structure, such as a gate post or frame.

[0112] The exit device 50 releasably secures the movable barrier to the fixed structure. The striker assembly 300 includes a striker bolt 306 configured to cooperate with the latch assembly 200 in a latching engagement. When the latch assembly 200 is proximate to the striker assembly 300, the striker bolt 306 can extend between the striker assembly 300 and the latch assembly 200 to secure the movable barrier relative to the fixed or fixable structure.

[0113] The actuator assembly 100 is operable to release the striker assembly and the latch assembly from latch engagement. The actuator assembly includes an actuator 102 and a first frame 110 mounted to a first elongated frame portion 104 via a plurality of rockers or bell cranks 108. In the form shown in the present application, the actuator 102 takes the form of a push rod.

[0114] The actuator 102 is an elongated member extending generally along a longitudinal axis between ends. The actuator 102 comprises a push surface and two side walls extending from the push surface towards the first frame 110 in use.

[0115] Likewise, the first frame 110 extends along the same longitudinal axis as the actuator 102 and extends between a first end and a second end. The first end (i.e., distal end) of the first frame 110 is configured to abut against the end wall 104d of the first elongated frame portion. The second end (i.e., proximal end) includes an engagement flange that protrudes away from the first frame portion 104 in use. The engagement surface 116 of the engagement flange is configured to engage with the second frame 210 of the latch assembly. Figure 5 As shown, the engagement surface 116 of the second end can be arranged, such as formed, perpendicular to the longitudinal length of the first frame 110, in the form of a foot. The engagement surface 116 provides a surface area for the first frame 110 to contact, such as engage, the second frame 210.

[0116] Similar to the actuator and the first frame, the first frame portion 104 also extends generally along the longitudinal axis between the ends and includes a base 104a having an upwardly extending sidewall 104b. The sidewalls 104b define a channel 104c therebetween for receiving the first frame 110. The sidewalls 104b are spaced apart from one another so that when the first frame is received between the sidewalls 104b, i.e., within the channel 104c, a space, i.e., a gap, is provided between the sidewalls 104b and the two sidewalls of the first frame 110. The spaced apart sidewalls 104b and the first frame 110 of the respective first frame portion 104 allow the first frame 110 to be movable, e.g., slidable, within the channel 104c without interference, e.g., by frictional contact.

[0117] An upwardly extending end wall 104d is provided at the first end of the first frame portion 104 to limit the movement, ie, sliding movement, of the first frame body 110 relative to the first frame portion 104. The second end of the first frame portion 104 is configured relative to the second frame portion 105 of the latch assembly 200 (described in more detail later).

[0118] The first housing 110 , the actuator 102 and the first frame portion 104 are connected together by an arrangement of a rocker 108 and a pin 112 .

[0119] First, referring to the first frame 110 and the first frame portion 104, the first pin 112a is fixed to the side wall 104b of the first frame portion 104. Figure 4 As shown, the central portion of the pin 112a passes through a slot 110a provided in the first frame 110. Spaced apart from the first pin 112a, the second pin 112b is fixed between the side walls of the first frame 110. The first pin 112a and the second pin 112b are connected by a spring 114. The spring 114 biases the first pin 112a and the second pin 112b toward each other. In the configuration shown, the spring 114 is a tension spring, which enables the first pin and the second pin to be biased toward each other.

[0120] like Figure 1 , Figure 2 and Figure 4 As shown, two rockers 108 are provided to connect the actuator 102 to the first frame portion 104 and the first frame 110. The two rockers 108 are spaced apart along the length of the actuator 102. Although two rockers are shown, it should be understood that more than two rockers may be provided. The rockers are generally triangular in shape, and in the illustrated embodiment, the rockers are generally right-angled in shape. The ends of the triangular rockers are rounded.

[0121] The first portion of each rocker 108 is pivotally connected to the actuator 102 via a first pin 108a. The second portion of each rocker 108 is pivotally connected to the flange 106 extending from the side wall 104b of the first frame portion 104 via a second pin 108b. The third portion of each rocker 108 is pivotally connected to the first frame 110 via a third pin 108c.

[0122] The flange 106 extends from the side wall 104b to complement a corresponding cutout in the side wall of the actuator 102 (at Figure 6 and Figure 7 ). Advantageously, this allows the pins 108a and 108b to be generally aligned about the longitudinal axis so that the actuator 102 can be positioned (i.e., by pivoting about the rocker 108) proximal to the first frame portion 104. As will be explained in more detail later, when the actuator is positioned proximal to the first frame portion, the actuator is considered to be in the depressed position.

[0123] In the form shown, the rocker 108 is triangular in shape, whereby the configuration of the pins 108a to 108c described above is located at the respective ends of the rocker 108. The positions of the pins 108a, 108b, 108c in each rocker 108 are arranged to amplify the force F that depresses the actuator 102 to a higher lateral force U to displace the first frame 110. As shown, the fulcrum of each rocker 108 is around the pin 108b, and by having an increased distance between the pins 108a and 108b and between the pins 108b and 108c, an amplified lateral force for displacing the first frame 110 can be achieved. This results in less force being required to push the actuator 102 during actuation. The pins 108a, 108b, 108c are located towards the ends of the rocker 108. The rocker 108 is mounted internally, i.e., between the two side walls of the actuator 102. Advantageously, this generally conceals the rocker 108 within the actuator assembly 100 such that movement of the rocker 108 during use is hidden from view.

[0124] The rocker 108 allows the actuator 102 to move in a lateral direction (relative to the longitudinal axis of the first frame portion 104). The rocker 108 is arranged so that during lateral movement of the actuator 102, the actuator 102 remains substantially parallel to the first frame portion 104. Figure 1 In the form best shown in FIG. 1 , a spacer 'S' is disposed on (i.e., coaxial with) the pin 108b to space between the rocker 108 and the flange 106. The spacer 'S' can stabilize the rotation of the rocker 108 and, in turn, the parallel movement of the actuator 102 during its use (i.e., actuation).

[0125] Reference now Figure 5 , the latch assembly 200 includes a latch body 202 for housing and / or supporting components of the latch assembly 200, and a second frame 210 movably mounted to the second frame portion 105. Contained within the latch body 202 and the second frame portion 105 are a retainer latch member 206, a retainer 204, and a magnet 214. Structural features, such as ribs, abutments, etc., may be formed on the inner wall of the latch body 202 and are configured to support the retainer latch member 206 and the retainer 204 in their respective positions.

[0126] The second frame 210 includes an abutment flange that protrudes away from the second frame portion 105 in use. An abutment surface 210a of the abutment flange of the second frame 210 is arranged to abut the engagement surface 116 of the first frame 110. The engagement surface 116 and the abutment surface 210a allow the second frame 210 to be movable, i.e., slidable, relative to the second frame portion 105 when the first frame 110 moves relative to the first frame portion 104. The abutment surface 210a is similar in shape to the engagement surface 116 of the first frame 110 in that the abutment surface 210a is arranged (e.g., formed) perpendicular to the longitudinal length of the second frame 210. In this way, the vertical engagement surface 116 of the first frame presses against the vertical abutment surface 201a of the second frame to move the second frame 210 during use.

[0127] The second bracket abutment face 210a is also arranged for actuating, ie moving, the keeper latch member 206. The keeper latch member 206 extends between a first end 208a and a second end 208b and is pivotally mounted to the latch body 202 about a pin 206a disposed between the ends 208a, 208b.

[0128] The retainer latch member 206 is provided with a biasing device (not shown) so that the first end 208a is biased to abut against the inner face (i.e., opposite the abutment face 210a) of the abutment flange of the second frame 210. In turn, the biasing device applies pressure, i.e., a biasing force, to hold the second frame 210 against the first frame 110.

[0129] The rotatable member 208c is disposed on the second end 208b of the retainer latch member 206. The biasing means (not shown) of the retainer latch member 206 also biases the rotatable member 208c into engagement with the retainer 204. In this manner, the retainer latch member 206 and the retainer 204 are mated (as described in more detail below). In addition, the biasing means disposed on the retainer latch member 206 (i.e., the biasing member 206 around the pin 206a) biases the retainer latch member 206 to rotate in a clockwise direction (when viewed through the page).

[0130] The retainer 204 includes a latching surface 204a and a striking surface 204c, and is pivotally mounted to the latch body 202 by a pin 204b disposed between the latching surface and the striking surface. The retainer 204 is provided with a biasing device (not shown) so that the striking surface 204c is biased to move toward the opening of the recess 202a in the latch body 202, i.e., to close the opening of the recess 202a in the latch body 202. That is, the retainer 204 is biased to rotate in the clockwise direction.

[0131] The retainer latch member 206 can be in an engaged position (ie, engaged with the retainer, such as about the pin 206a). Figure 5) and a released position (i.e., released from engagement with the retainer, as shown Figure 6 In the engaged position, the retainer latch member 206 is arranged upright, i.e., generally vertically, such that the extended length of the member 206 is generally perpendicular to the longitudinal length of the first frame portion 104. In the released position, the retainer latch member 206 is generally horizontal relative to the first frame portion 104.

[0132] like Figure 5 As shown, the first end 208a of the retainer latch member 206 is provided with a flat surface, which is shaped to align with the inner surface of the abutment flange 210a when the retainer latch member 206 is upright (i.e., in the engaged position). In another embodiment (not shown), the retainer latch member 206 can be provided with a curved surface or a cam surface to reduce the contact area with the abutment flange 210a, so that when actuated by the abutment surface 210a of the second frame 210, the latch member 206 can be easily actuated when it pivots around the pin 206a.

[0133] The retainer 204 may be in a first position (i.e., in Figure 5 or Figure 6 shown in the position) and a second position (i.e., in Figure 7 As shown in the figure, Figure 5 or Figure 6 As shown, the retainer 204 may be in the first position when the retainer latch member 206 is in the engaged position or the released position.

[0134] The striking surface 204 c of the retainer 204 is shaped such that when the retainer 204 is in the first position, the striking surface 204 c closes the opening of the recess 202 a to form a closed recess for receiving the striker bolt 306 therein. Figure 5 and Figure 6 In contrast, when the retainer 204 is in the second position, the striking surface 204c moves away from the opening of the recess 202a, so that the recess 202a is opened.

[0135] The opened recess 202a is Figure 7 , whereby the retainer 204 in the second position opens a side of the recess away from the second bracket 210. As will be explained in more detail later, the opening in the recess allows the striker bolt 306 (of the striker assembly 300) to move through the recess, i.e., outwardly from the recess, when positioned in the recess.

[0136] The latch body 202 of the latch assembly 200 also includes a retaining portion 202c for retaining the magnet 214. In the illustrated form, the retaining portion is a cavity 202c configured to receive the magnet. In an alternative form (not shown), the retaining portion can be an arrangement of upright members spaced apart to support the magnet 214. In any case, the retaining portion 202c is configured to support the magnet in a fixed position within the latch body 202. The cavity 202c is configured to position (i.e., space) the magnet proximal to the recess 202a.

[0137] The spacing of the magnets relative to the recess 202a can be selected to optimize the magnetic force applied by the magnet 214 to the striker bolt 306 (i.e., when the striker assembly 200 is toward the latch assembly 200). For example, the cavity 202c can position the magnet 214 sufficiently close to the striker bolt 306 so that when the striker assembly 300 is near the recess 202a of the latch assembly 200, the striker bolt 306 is attracted toward the recess 202a and releasably retained therein. Figure 7 In the form shown, the magnets 214 are spaced apart by the wall 202d of the latch body.

[0138] Now refer to Figures 5 to 10 The striker assembly 300 is shown. The striker assembly 300 includes a striker body 302 for receiving a striker bolt housing 312 and a striker bolt assembly 310 therein. The striker bolt assembly 310 includes a striker bolt 306 that is movable within the striker bolt housing 312 (i.e., can extend from the striker bolt housing 312 and can be retracted into the striker bolt housing 312). The striker bolt assembly 310 also includes a mechanism for moving the striker bolt 306 toward a retracted position (e.g., Figure 8 A biasing device 308 is provided for biasing the device 308).

[0139] The striker assembly 300 also includes a mounting bracket 304 for releasably mounting between the striker body 302 and a fixed or fixable structure. As shown, the mounting bracket 304 also includes a mounting flange 304d extending vertically therefrom to provide an additional device for fixing the mounting bracket 304 to a fixed or fixable structure.

[0140] Brief reference Fig.11 and 12 , shows a perspective view of the actuator assembly 100 and the latch assembly 200 of the exit device 50 mounted to the movable barrier A. As explained in more detail below, the striker body 302 can be movably (e.g., slidably) retained relative to the mounting bracket 304 to change the gap between the striker assembly 300 and the latch assembly 200.

[0141] The striker body 302, and thus the striker housing 312, may be movably retained to the mounting bracket 304 about tracks (not shown) disposed on the respective striker body 302 and bracket 304. The tracks may extend along the elongated length of the respective striker body 302 and bracket 304, and may be slidably engaged with one another so that the striker body 302 may translate relative to the bracket 304 along the longitudinal axis of the outlet device 50, i.e., parallel to the extension / retraction of the striker bolt 306. The screw 314 and insert 316 may be used to allow controlled adjustment between the striker body 302 and bracket 304, as will be described in more detail below.

[0142] refer to Figure 5 , the striker bolt housing 312 includes a hole 312a for receiving the striker bolt 306. The striker bolt housing 312 and the hole 312a each extend along the same longitudinal axis as the outlet device 50, wherein each of the striker bolt housing 312 and the hole 312a extends between corresponding proximal and distal ends. The striker bolt 306 extends along the same longitudinal axis as the hole 312a and the striker bolt housing 312 (i.e., coaxially), and includes a proximal end 306b and a distal end corresponding to the corresponding ends of the housing 312. In use, when the striker bolt 306 is in the retracted position, the proximal end 306b of the striker bolt 306 remains in the hole 312a. Figure 8 As shown, when in the retracted position, the proximal end 306b is generally aligned with the proximal end of the housing 312.

[0143] The distal end 306b of the striker bolt 306 is configured to extend through the notch 312f in the hole 312a to be disposed within the striker bolt housing 312. The striker bolt 306 is coaxially arranged with the hole so that in use, the distal end of the striker bolt 306 can move (e.g., slide) from a retracted position to an extended position through the notch 312f. Figure 5 As shown, in the extended position of the striker bolt 306, the proximal end 306b of the striker bolt 306 protrudes from the hole 312a.

[0144] The movement of the striker bolt 306 from the retracted position and the extended position (i.e., between the retracted position and the extended position) can be limited by the annular flange 312b and the retaining member 306a of the corresponding striker bolt housing 312 and the striker bolt assembly 310. The annular flange 312b protrudes from the hole 312a of the striker bolt housing 312 and is constructed, i.e., positioned and shaped to limit the travel of the striker bolt 306 in a first direction, i.e., when moving toward the retracted position. The retaining member 306a is retained at the distal end 306c of the striker bolt 306 by the fastener 307 and is constructed (e.g., shaped) to abut the striker bolt housing 312 to limit the travel of the striker bolt 306 in a second direction (i.e., toward the extended position). This configuration of the flange 312b and the member 306a allows the proximal end 306b of the striker bolt 306 to extend from the housing 312 a distance set by the spacing between the flange 312b and the member 306a in use.

[0145] The biasing device 308 is disposed on and coaxial with the distal end of the striker bolt 306. In use, the biasing device 308 is located between the striker bolt housing 312 and the retaining member 306a. Thus, the biasing device 308 biases the striker bolt 306 between the "hard stop" point defined by the flange 312b and the member 306a, and corresponds to the respective retracted and extended positions of the striker bolt 306.

[0146] The biasing device 308 may be a compression spring for biasing the movement, i.e., displacement, of the striker bolt 306 from the extended position to the retracted position. That is, the compression spring 308 is used to move the proximal end 306b of the striker bolt 306 to reside in the hole 312a. Therefore, the compression spring 308 acts to resist the movement of the striker bolt 306 to the extended position. In other words, the striker bolt housing 312 is configured to receive the striker bolt 306 in the retracted position.

[0147] The impact block bolt 306 Figure 5 is shown in the extended position. Figure 8 , the striker bolt 306 is shown in a retracted position.

[0148] The striker body 302 also includes a flange 302a at its proximal end. The flange 302a is configured to mount a cover 302b around the striker body 302. In the illustrated form, the cover 302a forms an outer shell around the striker bolt housing 312.

[0149] An insert 316 in the form of a rack is secured to the striker body 302. The rack 316 includes a series of teeth that are configured (i.e., by pitch, height, etc.) to correspond to the external threads of the screw-form screw 314. In another embodiment (not shown), the rack 316 and its teeth may be integral with or formed on the striker body 302.

[0150] The recess 304a in the mounting bracket 304 is configured to receive the screw 314 and position the screw 314 relative to the rack 316. The recess 304a includes a flange 304b for supporting the end of the screw 314. In the illustrated form, the screw 314 is a worm screw with a tool interface. The flange 304b acts as a stop to prevent the worm screw 314 from moving laterally (i.e., in the direction of elongation) within the recess 304a.

[0151] A notch 304 c is provided in the mounting member 304 , coaxial with the worm screw 314 , for receiving a tool, such as a screwdriver, therethrough to rotate the worm screw 314 .

[0152] The recess 304a in the mounting bracket 304 allows the worm screw 314 to be rotated so that the engaging external threads of the worm screw 314 and the teeth of the rack 316 can operatively move the striker body 302 (and the housing 312) relative to the mounting bracket 304. In this manner, the corresponding threads and teeth allow the striker body 302 to be adjustable, i.e., by rotation of the worm screw 314, the striker body 302 can be moved to a selected position relative to the bracket 304.

[0153] The rack 316 allows the striker body 302 to be moved closer to or further away from the latch assembly in use. Thus, the rotational movement of the worm screw 314 is converted into movement of the striker body 302 in the lateral direction. In fact, when the striker bolt 306 is in the extended position, the adjustability of the striker body 302 enables the proximal end 306b of the striker bolt 306 to be positioned closer to or further away from the wall 202d of the recess 202a of the latch assembly 200. In turn, this allows the proximal end 306b of the striker bolt 306 to engage with the strike face 204c, so that the striker bolt 306 is securely held in latch engagement by the latch member 204.

[0154] In some cases, the optimal position of the striker body 302 can be determined by the spacing between the fixed obstacle and the movable obstacle. The striker body 302 can be adjusted to a position whereby the striker bolt 306 can extend through the spacing between the obstacles and be received in the recess 202a of the latch assembly 200. In this regard, the spacing that the striker bolt 306 extends between the obstacles can be referred to as the "strike distance". Therefore, the threads of the worm screw 314 and the teeth of the rack 316 allow the striker body 302 to be adjusted to the desired (i.e., correct) strike distance.

[0155] When the striker body 302 (and thus the striker assembly 300) is positioned at the correct strike distance, the striker bolt 306 can engage with the striker surface 204c or recess 202a (i.e., a component of the latch assembly 200), as previously described. Thus, the striker body 302 can be adjustable so that when the striker bolt 306 is moved to the extended position (i.e., when close to the latch assembly 200), the striker assembly 300 can engage with the latch assembly 200 in a latching manner.

[0156] As described above, the striker body 302 and the striker bolt housing 312 are formed as an integral component. Alternatively, the striker body 302 and the striker bolt housing 312 may be separate components.

[0157] exist Figure 5 In the latched state shown, the striker bolt 306 can be retained in the recess 202a in the extended position when the retainer 204 is retained in the first position (in the engaged position) by the retainer latch member 206. When the retainer latch member 206 and the retainer 204 are in these respective positions, the retainer 204 closes the opening of the recess 202a to prevent the striker bolt 306 (and therefore the striker bolt assembly 300) from moving away from engagement with the striker surface 204c (and wall 202d) of the latch assembly 200.

[0158] In this manner, the striker bolt 306 connects the latch assembly 200 to the striker assembly 300 around the recess 202a. When the retainer 204 is in the first position, the striker surface 204c can securely engage the striker bolt 306 (i.e., resist movement of the striker bolt 306) to prevent the striker bolt 306 from moving away from the magnetic engagement with the latch assembly. Thus, when the retainer 204 is in the first position, the movable barrier can be held in a closed position (relative to the fixed structure) by the striker bolt 306.

[0159] The latch body 202 also includes a stop 202b to limit the rotation of the retainer 204. When the retainer 204 is in the first position, the stop 202b is positioned to contact the latch face 204a. The stop 202b can support the retainer 204 in the first position so as to provide a gap between the impact face 204c and the proximal end 306b of the striker bolt 306. That is, the stop 202b prevents the retainer 204 from rotating excessively in the clockwise direction, thereby closing the recess 202a (i.e., reducing the size of the recess 202a). Advantageously, when the magnet 214 biases the proximal end 306b of the striker bolt 306 into the recess 202a, the gap allows the striker bolt to move past the impact face 204c with minimal or no obstruction.

[0160] When the retainer 204 is in the first position and the striker bolt 306 is retained by and engaged with the latch assembly 200 (i.e., in the extended position), the exit device 50 can be considered to be in a latched state, whereby the latch and striker assemblies 200, 300 are in latched engagement. In this manner, when the retainer 204 is in the first position, the striker surface 204c is engaged with (i.e., fixed to) the striker bolt 306 to retain the striker bolt 306 in its extended position (i.e., latched engagement). Figures 1 to 5 is shown in a latched state.

[0161] like Figure 5 As shown, when the retainer latch member 206 is in the engaged position, the second end 208b of the retainer latch member 206 engages the latching surface 204a of the retainer 204 (around the rotatable member 208c) to retain the retainer 204 in the first position.

[0162] Reference now Figure 6 and 7 When the retainer latch member 206 moves to the release position, the second end 208b of the retainer latch member 206 (rotates counterclockwise and) disengages from the latching surface 204a of the retainer 204. When the retainer latch member 206 is in the release position, the retainer 204 is operable to move to the second position to open the recess 202a. This enables the striker bolt 306 to move outward from the recess 202a, thereby allowing the movable barrier to be movable relative to the fixed structure so that the movable barrier can be moved to the open position.

[0163] When the retainer 204 is in the second position and the striker bolt 306 is free to move through the opening of the recess 202a, the exit device 50 can be considered to be in an unlocked state, whereby the latch and striker assemblies 200, 300 are free to move relative to each other in an unlocked relationship. Figure 7 is shown in the unlocked state.

[0164] Reference is now made to the latched state, i.e., the engaged position, of the retainer 204 and the retainer latch member 206, as shown in FIG. Figure 5 In the arrangement shown, the latch face 204a is fixed between the rotatable member 208c and the stopper 202b to prevent the latch member 204 from rotating. This enables the striker face 204c to close the opening of the recess 202a and prevent lateral movement of the striker bolt 306, so that the striker 300 is firmly engaged with the latch assembly 200 and cannot be moved from the recess 202a.

[0165] When in the latched state, the magnetic force of the magnet 214 applied to the proximal end 306b of the striker bolt 306 is greater than the biasing force applied to the striker bolt 306 by the biasing device 308. Thus, when the latch assembly 200 approaches the striker assembly 300, the magnet 214 magnetically biases the proximal end 306b of the striker bolt 306 to move to the extended position so as to reside in the recess 202a. In this position, the latch assembly 200 holds the striker bolt 306 in the extended position so that the latch device is in the latched position.

[0166] In this regard, the biasing force applied by the magnet is stronger than the biasing force applied by the biasing means, i.e., spring 308. This means that the biasing force of spring 308 retracts striker bolt 306 only when the striker assembly is moved away from the vicinity of magnet 214. Conversely, when striker assembly 300 is aligned with latch assembly 200, the biasing force applied by the magnet moves striker bolt 306 to the extended position to engage with latch assembly 200.

[0167] refer to Figure 6 , the actuator assembly 100 and the latch assembly 200 are mechanically connected so that the latch assembly 200 can be actuated by the actuator assembly 100. The first frame 110 of the actuator assembly 100 is configured to move the second frame 210 relative to the actuator 102. As previously described, when the actuator 102 is in its raised position, the first end (i.e., distal end) of the first frame 110 abuts the end wall 104d of the first elongated frame portion. The engagement surface 116 of the second end (i.e., proximal end) (of the first frame 110) contacts the abutment surface 210a of the second frame to actuate the second frame 210 of the latch assembly 200.

[0168] In the form shown in the present application, the frame portion 104 and the second frame portion 105 are separate components. In some alternative forms (not shown), the first and second portions may be formed from a single component, ie, a single portion extending between the actuator assembly 100 and the latch assembly 200.

[0169] Actuation of the second frame 210 causes the second frame 210 to shift, for example, slide, between the active position and the neutral position relative to the second frame portion 105. Figure 5 , the first frame 110 and the second frame 210 are shown to be in respective intermediate positions. Figure 6 When the first carrier displaces the second carrier during actuation of the actuator 102, the second carrier displaces, for example, to the active position, whereby the retainer latch member 206 also moves (eg, rotates) to the release position by engaging with the second carrier.

[0170] When the retainer latch member 206 is in the released position, the striker bolt 306 can movably engage the striker surface 204c to move the retainer 204 to the second position (i.e., open the recess 202a). This allows the striker bolt 206 to move from the recess, thereby moving the proximal end 306b of the striker bolt 306 away from the magnet 214. This moves the striker bolt 306 out of alignment with the magnet, or substantially out of alignment with the latch assembly 200, so that the striker bolt can move (from its extended position) to the retracted position.

[0171] The actuator assembly 100 acts on the latch assembly to release the movable barrier to the open, unlocked position. Figures 5 to 8 The order is shown, where first, Figure 5 , the exit device 50 is shown in a latched state and the actuator 102 is in a raised position. Figure 6 The exit device 50 is shown in an unlocked state, wherein the actuator 102 is in a depressed position when a force P is applied to the actuator 102 .

[0172] When force P is applied to the actuator 102, force P is transferred to the first pin 108a to rotate the rocker 108 around (i.e., around) the corresponding second pin 108b. At the same time, the rotation of the rocker 108 applies force U on the corresponding third pin 108c and displaces the first frame 110, i.e., moves from the neutral position.

[0173] Application of force P results in depression of actuator 102 in a first direction, i.e., a path of travel indicated by force P (i.e., acting transversely to the longitudinal axis of the elongated frame). Corresponding rotation of rocker 108 translates force P through angular rotation to move first frame 110 in a second direction, i.e., a path of travel transverse to the first direction.

[0174] When the first frame 110 moves in the second direction, the first frame 110 moves to the drive position, whereby the engagement surface 116 of the first frame 104 actuates, i.e. engages, the corresponding abutment surface 210a of the second frame 210. This causes the second frame to shift from the neutral position, i.e. move to the active position. This in turn forces the retainer latch member 206 to rotate against its bias (as described above, but not shown) so as to disengage, i.e. move, the rotatable member 208c from the latch surface 204a. At this point in the actuation, the latch surface 204a is no longer fixed between the rotatable member 208c and the stop 202b.

[0175] When the retainer latch member 206 moves to the release position, the biasing device of the retainer 204 (described above, but not shown) maintains the bias on the strike surface 204c to close the opening of the recess 202a. Figure 5 and 6As shown, this allows the retainer 204 to be in the first position when the retainer latch member 206 is in the engaged position or the released position.

[0176] refer to Figure 7 , once the retainer latch member 206 is in the released position and the retainer 204 is not restrained by the retainer latch member 206, the striker bolt 306 can engage the impact surface 204c to force the retainer 204 to rotate against its biasing device. When the retainer 204 is rotated to the second position, the impact surface 204c no longer closes the opening of the recess 202a. This enables the striker bolt 306 to pass through the opening of the recess 202a when the movable barrier is initially moved. In this arrangement, the exit device 50 is in an unlocked state, whereby the latch assembly 200 can be laterally displaced relative to the retainer 204 to allow the movable barrier to open in the direction of the force P.

[0177] In some forms, the actuator 102 may be configured such that movement from its raised position to the partially depressed position moves the retainer latch member 206 to the released position. Further depression of the actuator 102 from the partially depressed position to the depressed position enables the striker bolt 306 to engage the striker surface 204c to move the retainer 204 to the second position. This configuration (i.e., including movement through a partially depressed stage) differs from the alternative form described above, in which the actuator 102 is configured to move between a fully raised position and a fully depressed position (for corresponding movement of the retainer 204 between the first position and the second position).

[0178] Reference now Figure 8 , when the force P is removed from the actuator 102 so as to release the actuator 102, the actuator 102 is biased in the direction of the arrow indicated by "Closed, C" to the raised position. As previously described, the spring 114 is used to bias the first frame 110 relative to the frame portion 104 so that when the actuator 102 is in the depressed position, the first pin 112a and the second pin 112b are spaced farther apart (compared to when the actuator is in the raised position), causing the spring 114 to extend. This biases the spring 114 so that the spring is used to bias the actuator 102 to the raised position. In turn, this causes the first frame 110 and the second frame 210 to move to respective neutral positions.

[0179] As the first and second frames move away from their respective drive and active positions, the retainer latch member 206 rotates (due to its bias) to the engaged position. As previously described, the retainer 204 is also biased so that the retainer remains in the first position without forced rotation to move the striker bolt from the recess 202a. Thus, once the actuator 102 is released and the retainer latch member 206 returns to the engaged position, the retainer 204 is engaged by the latch member 206, i.e., fixed in the first position.

[0180] When the actuator 102 is in the raised position, the spacing, i.e., the position of the actuator 102 relative to the first frame 110, is determined by the size and position of the slot 110a. In other words, the protrusion of the actuator is determined by the slot 110a. Figure 4 As best shown in FIG. 1 , the slot 110a disposed in the side wall of the first frame 110 is sized and positioned to limit the amount of travel of the first frame 110 relative to the first frame portion 104. For example, the length of the slot 110a can control the spacing of the actuator 102 from the first frame 110 when in the raised position.

[0181] like Figure 8 As shown, once the actuator 102 has been released to the raised position and the latch assembly 200 has been moved away from the striker assembly 300 (i.e., unlocked), the striker bolt 306 is no longer in proximity to the magnet 214. In this position, the magnetic force applied to the proximal end 306b of the striker bolt 306 is weakened, so that the biasing device 308 of the striker assembly 300 biases the striker bolt 306 to its retracted position. In the retracted position, the proximal end 306b of the bolt 306 no longer extends beyond the striker bolt housing 312.

[0182] When compared Figure 5 and Fig.10 It is apparent that when the movable barrier is closed and the latch assembly 200 approaches the striker assembly 300, the magnet 214 biases the head of the striker bolt 306 to extend into the recess 202a. In this way, the latch assembly 200 cooperates with the striker assembly 200 to engage the corresponding components in a latching engagement.

[0183] Reference now Fig. 9 , the latch assembly 200 also includes a remote actuator 212 connected to the second frame 210. The remote actuator 200 can be used to displace the second frame 210 between the active position and the neutral position relative to the second frame portion 105. In practice, the remote actuator is operable to move the retainer latch member 206 between the engaged position and the released position. In this way, the remote actuator can bypass the actuator assembly 100 to operate the latch assembly 200.

[0184] The latch assembly 200 may be operated by a remote actuator 212 to allow operation of the exit device 50 from a remote side of the movable barrier. Fig. 9 In the illustrated form, the remote actuator is positioned on an opposite side of the latch assembly 200 relative to the second frame portion 105. In other forms not shown, the remote actuator may be configured to operate from an alternate location on the exit device 50.

[0185] The remote actuator 212 may be coupled to a remote driver at a first end 212b of the remote actuator 212. Fig. 9 or Fig.10 The remote driver is not shown, but Fig.11 and Fig.12 An example of a remote driver 400 is shown in FIG. The remote actuator 212 can be operated by the remote driver to enable the retainer 204 to be retained in the first position (i.e., when the retainer latch member 206 is engaged with the retainer 204). Alternatively, when the retainer latch member 206 is disengaged from the retainer 204 (i.e., when the retainer 204 is released), the driver can be operated to enable the retainer 204 to move from the first position to the second position. That is, when the movable barrier is opened, the retainer 204 is moved to the second position by the striker bolt 306.

[0186] The remote actuator 212 is configured to be coupled to the second frame 210 near the second end of the remote actuator 212. As shown, the second end of the remote actuator 212 includes a cam 212a (shown in a side cross-sectional view). When the remote actuator 212 rotates R, the rotational movement of the remote actuator 212 is converted into a linear movement of the second frame 201a by the cam 212a. The linear movement causes the actuation of the second frame 210 and moves the second frame to the active position. In this regard, the cam 212a is mechanically connected to the second frame 210 for controlling the movement of the second frame between the neutral position and the active position.

[0187] When the second bracket is moved to the active position by the remote actuator, the abutment surface 210a also moves to contact and thereby rotate (in this case, against by the pulling movement of the abutment surface 201a) the retainer latch member 206. In fact, the rotatable member 208c also rotates with the rotation of the retainer latch member 206. When the abutment surface 210a of the second bracket contacts the first end of the retainer latch member 206 to rotate the retainer latch member 206 away from engagement with the retainer 204, the retainer 204 is released to move to the second position. In this way, the latch surface 204a is no longer fixed between the rotatable member 208c and the stop 202b. In this arrangement, the biasing device of the retainer 204 maintains a bias on the strike surface 204c so as to close the opening of the recess 202a once the striker bolt 306 moves away from the latch assembly.

[0188] Reference now Fig.10Once the retainer 204 is released from the first position and no longer engaged with the retainer latch member, applying an opening force O on the remote actuator 212 allows the striker bolt 306 to engage the striker surface 204c to rotate the retainer 204 against its biasing means. As the retainer 204 rotates, the striker surface 204c no longer closes the opening of the recess 202a, and this allows the striker bolt 306 to pass through the opening of the recess 202a. In effect, the latch assembly 200 is laterally displaced relative to the striker assembly 300, allowing the movable barrier to open in the direction of the opening force O.

[0189] Although Fig. 9 and Fig.10 The illustrated embodiment discloses the remote actuator 212 as being rotationally operable, but it is contemplated that the remote actuator 212 may be linearly operable. For example, the remote actuator may be configured such that depression of the remote actuator unlocks the latch assembly 200 (as previously described). In this manner, it is contemplated that the remote actuator 212 operates in a linear path that is transverse to the displacement path of the second carriage 210.

[0190] Reference now Fig.12 , shows a passage device including an actuator assembly 100, a latch assembly 200, and a remote actuator 400 of an exit device 50 mounted to a movable barrier A. The remote actuator 400 is mounted on a side of the movable barrier A opposite the latch assembly 200. Although not shown, it is contemplated that the striker assembly 300 is mounted to a fixed structure and can be aligned with the latch assembly 200 to secure the movable barrier A in a closed position when the movable structure is facing the fixed structure. In this case, when the exit device 50 is in a latched state, that is, when the retainer latch member 206 is in an engaged position and the retainer 204 is in a first position, the fixed structure and the movable structure can be secured together.

[0191] Fig.11 Shown with Fig.12 Similar arrangement, different from Fig.12 4 is a partially exploded view in which the remote drive 400 is in an offset position (relative to Fig.12 A notch A1 is provided in the movable barrier A to allow the remote actuator 212 of the actuator assembly 200 to be coupled to the remote driver 400 .

[0192] The remote driver 400 includes a release mechanism 402 that can be operated to actuate the remote actuator 212 of the latch assembly 200, such as by rotation or linear compression. As shown, the release mechanism 402 of the remote driver 400 is positioned higher than the actuator assembly 100, such as near the top of the movable obstacle A.

[0193] The higher position of the release mechanism is advantageous for safety applications where entry into a fenced or restricted area is restricted, but exit may be unrestricted. This may be particularly advantageous for swimming pool barriers where local regulations require that the height of the release mechanism 402 on the swimming pool entrance gate be placed at a minimum height above ground level to prevent young children from operating the mechanism 402 and gaining access to the swimming pool area. The exit device 50 located at a relatively low position will allow smaller children to exit the swimming pool area. To prevent young children from operating the exit device 50 from the other side of the boundary, a guard (not shown) may be provided.

[0194] In an alternative embodiment, Fig.12 The remote drive 400 can be replaced by an electronic or mechanical keyboard actuator kit, an RFID actuator kit, a wireless actuator kit, an electronic actuator kit, an electromechanical actuator kit, or other mechanical actuator kit.

[0195] Reference now Figures 13 to 23 , an alternative embodiment of a striker assembly 500 is shown. The striker assembly 500 includes a striker body 502 configured to receive a striker bolt assembly 510. The striker bolt assembly 510 is secured to the striker body 502 relative to an insert 516 configured to be received in an inner cavity 502a defined by an inner surface of the body 502.

[0196] The striker assembly 500 is similar to the striker assembly 300 previously described, with the primary difference being that the striker body 502 and the striker bolt housing 512 are separate components, whereby the striker bolt 506 and the striker bolt housing 512 form a striker bolt assembly 510 that is configured to be positionally adjustable relative to the striker body 502. This enables the striker bolt 506 to be positioned closer to or further away from the recess 202a of the latch assembly 200 when the striker bolt 506 is in the extended position. Figures 4 to 10 In a similar manner to that shown in FIG. 1 , another embodiment of the striker assembly 500 also allows the striker bolt assembly 510 to be optimally positioned to allow the proximal end 506b of the striker bolt 506 to be received in the recess 202a (against the wall 202d) of the latch assembly 200 when in the extended position. In turn, this allows the proximal end of the striker bolt 506 to engage with the striker surface 204c, so that when the latch assembly and the striker assembly are in the latched state, the striker bolt 506 is securely retained by the retainer 204.

[0197] Reference now Fig.15, the striker bolt assembly 510 includes the striker bolt housing 512, which has a hole 512a for accommodating the proximal end 506b of the striker bolt 506 (when the striker bolt 506 is retracted). The striker bolt housing 512 extends along the same longitudinal axis (i.e., coaxially) as the striker bolt 506 and extends between the proximal end and the distal end. In use, the proximal end of the housing 512 is generally aligned with the proximal end 506b of the striker bolt 506 (when in the retracted position). The distal end of the striker bolt housing 512 is disposed within the striker body 502.

[0198] An annular flange 512b is disposed within the bore 512a to limit travel of the striker bolt 506 in a first direction (i.e., away from the latch assembly 200 in use). A retaining member 506a (i.e., a nut) is disposed on a distal end of the striker bolt 506 for abutting the housing 512 to limit travel of the striker bolt 506 in a second direction (i.e., toward the latch assembly 200 in use). In use, the biasing device 508 is disposed on the striker bolt 506 between the annular flange 512b and the retaining member 506a and is coaxial with the striker bolt 506.

[0199] Thus, the biasing device 508 biases the movement, i.e., displacement, of the striker bolt between the "hard stop" points defined by the flange 512b and the member 506a. In effect, this biases the proximal end 506b of the striker bolt 506 to reside within the hole 512a (i.e., when in the retracted position). Furthermore, this allows the striker bolt 506 to extend from the housing 512 a distance set by the spacing between the flange 512b and the member 506a. In this manner, the striker bolt housing 512 is configured to receive the striker bolt 506 in the retracted position.

[0200] The housing 512 also includes a flange 512c at the proximal end. The flange is configured with a pair of parallel flat surfaces 512d (i.e., configured as a non-circular end). As shown, the flange 512c extends between the pair of parallel flat surfaces, i.e., so as to extend at least partially around the proximal end. The pair of parallel flat surfaces 512d provides a gripping surface for a tool (e.g., a wrench) to hold and rotate the striker bolt assembly 510 relative to the striker body 512.

[0201] The housing 512 also includes an external thread 512e disposed on a central portion of the housing 512 (i.e., between the proximal and distal ends). The thread 512e is configured (i.e., by pitch, diameter, etc.) to correspond to the mating threaded hole 516a of the insert 516. In this manner, at least a portion of the outer surface of the striker bolt housing 512 is formed (i.e., separately formed) on the insert 516. The threaded hole 516a is configured to receive the striker bolt assembly 510, whereby the external thread 512e of the housing 512 engages with the threaded hole 516a. As described below, the external thread 512e of the housing can be used together with the threaded hole 516a to move the striker bolt assembly 510 to a selected position.

[0202] The corresponding threads 512e, 516a allow the striker bolt assembly 510 to be adjustable, i.e., by being rotated relative to the striker body 502, so that the striker bolt assembly 510 can be moved to a selected position relative to the striker body 502. The selected position is selected to align the striker bolt assembly 500 with the latch assembly 200 when the striker bolt 506 is in the extended position. In other words, the selected position of the striker bolt assembly 510 can align the proximal end 506b of the striker bolt 506 with the wall 202d of the recess when the striker bolt 506 is in the extended position.

[0203] The external threads 512e on the housing 512 allow the striker bolt assembly 510 to move closer to or away from the latch assembly 200 in use. In this way, the threads 512e allow the striker bolt assembly 510 to be adjusted (to the optimal position) so that the striker assembly 500 and the latch assembly 200 can be in latching engagement.

[0204] like Fig.16 and 17 As shown, the striker bolt assembly 510 is fixed relative to the insert 516 by a locking member 518. As shown, the locking member 518 extends between a first end and a second end in a direction transverse to the longitudinal (i.e., elongation) extent of the insert 516. In use, a first side of the locking member 518 is located at an inner surface of the inner cavity 502a of the striker body 502 (i.e., adjacent to the inner cavity 502a of the striker body 502). The second end of the locking member 512 is arranged (as described below) near the striker bolt housing 512 in use.

[0205] The locking member 518 is located in the inner cavity 502a of the striker body 502, and in the illustrated form, the locking member 518 is located in a cavity provided in the insert 516. The insert 516 is also located in the cavity 502a, so that the combination of the insert 516 and the locking member 518 secures the striker assembly 510 to the striker assembly 500.

[0206] Reference now Fig. 20 and Fig.21, the first end of the locking member 518 includes an inclined surface 518a for cooperating with a corresponding inclined surface 502b on the inner cavity 502a of the striker body 502. In the illustrated form, the corresponding inclined surface 502b of the striker body 502 is formed as part of the inner surface of the striker body 502, i.e., continuous with the inner surface of the striker body 502. In other forms not shown, the corresponding inclined surface 502b can be formed separately from the body 502, for example, as part of a separate base for assembly with the body (i.e., as part of the body).

[0207] The second end of the locking member 518 includes an engagement surface 518b for engaging an abutment surface of the striker bolt housing 512 when in the locked position. In the illustrated form, the abutment surface is an external thread 512e of the striker bolt housing 512. The inclined surface 518a and the corresponding inclined surface 502b are capable of guiding the locking member 518 from the locked position to the unlocked position (i.e., between the locked position and the unlocked position), as explained in more detail below.

[0208] An externally threaded actuator in the form of a screw 514 is provided to move the locking member 518 relative to the striker bolt housing 512. An internally threaded passage is provided in the locking member 518 and is configured to receive and engage the screw 514. A corresponding notch 516b is provided in the insert 516 and is aligned with the internally threaded passage when in use for receiving the screw 514 therethrough. The notch 516b includes a shoulder for supporting the head of the screw 514. The size of the notch (i.e., diameter) is set to at least allow the shaft of the screw 514 to be received therethrough without interference. The size of the shoulder is designed to support the head of the screw 514 so that when the screw 514 engages with the internally threaded passage of the locking member 518, the head is held by the shoulder. This configuration allows the screw 514 to rotate freely within the notch 516b while the threaded portion of the screw 514 engages with the threaded passage of the locking member 518.

[0209] The internal threaded passage allows the screw 514 to move the locking member 518 between the locked position and the unlocked position relative to the striker bolt housing 512. In the illustrated form, the screw 514 moves the locking member 518 relative to the insert 516 to enable the locking member 518 to move further between the locked position and the unlocked position (i.e., toward and away from the housing 512).

[0210] Figures 20 to 22 The steps for adjusting the position of the striker bolt assembly 510 relative to the insert 516 and the housing 502 are shown. Fig.21Before the locking member 518 is rotated in the direction D shown in the figure, the engagement surface 518b of the locking member 518 needs to be disengaged from the external thread 512e of the housing 512 by rotating the screw 514. This initial position of the locking member, i.e., the position where the engagement surface 518b is engaged with the external thread 512e, is Fig.18 Shown in.

[0211] Fig.18 The arrangement of the striker assembly shown in can be provided for packaging and transportation of the assembly, such as shipping, before installation on, for example, a fence. In this arrangement, the engagement surface 518b of the locking member 518 is shown in an engagement position with the external thread 512e of the housing 512 to secure (e.g., lock) the striker bolt in a fixed position.

[0212] Reference now Fig. 20 , when the screw 514 is rotated R, the locking member 518 moves downward along the inclined surface 502b in the direction indicated by D (from the locked position to the unlocked position). This movement moves the locking member 518 away from the thread 512e, thereby releasing the engagement surface 518b from the external thread 512e. In this way, the rotational movement of the screw 514 is converted into the movement of the locking member 518 in the lateral direction (i.e., in the direction of the longitudinal axis).

[0213] Once the locking member 518 is released, the striker bolt assembly 510 may be rotated R', as shown in FIG. Fig.21 As previously described, this can be achieved by securing a pair of parallel flat surfaces 512d of housing 512 with, for example, a wrench and rotating housing 512 until striker bolt assembly 510 moves displacement D' into a selected position. In this manner, striker bolt housing 512 is free to move (i.e., rotatable about threads 512e) when locking member 518 is in the unlocked position.

[0214] As for the embodiment of the impact block assembly 300 ( Figures 4 to 10 ), the selected position, i.e., the optimal "correct" position of the housing 512, can be determined by the spacing between the fixed obstacle and the movable obstacle. The housing 512 can be adjusted (as described above) to a position whereby the striker bolt 506 can extend through the spacing between the obstacles and be received within the recess 202a of the latch assembly 200. Thus, the corresponding threads 512e, 516a of the respective housing 512 and insert 516 allow the striker bolt assembly 510 to be adjusted to the desired, i.e., correct, strike distance.

[0215] When the striker bolt assembly 510 (and thus the striker assembly 500) is positioned at the correct striking distance, the striker bolt 506 can engage with the striking surface 204c of the recess 202a (i.e., a component of the latch assembly 200). Therefore, the striker bolt assembly 510 can be adjustable so that when the striker bolt 506 is moved to the extended position (i.e., when close to the latch assembly 200), the striker assembly 500 can be engaged with the latch assembly 200.

[0216] Once the correct strike distance is selected for the striker bolt assembly 510 (as described above), the locking member 518 may be applied to secure the striker assembly 510 in place. Fig. 22 As shown, the engagement surface 518b of the locking member 518 can be engaged with the external thread 512e of the housing 512 by rotation R" of the screw 514. When the screw 514 is rotated, the locking member 518 moves upward along the inclined surface 502b, represented by the displacement D". This causes the engagement surface 518b to move to engage with the external thread 512e so as to fix, i.e., prevent, the housing 512 from rotating. In other words, when the locking member 518 is in the locked position, the locking member 518 engages the impact block bolt housing 512 to hold the impact block bolt housing in a selected position.

[0217] Advantageously, locking member 518 prevents striker bolt assembly 510 from being inadvertently adjusted during use. For example, locking member 518 can secure striker bolt assembly 510 so that vibrations of the gate (typically occurring during gate closing) do not change the position of striker bolt assembly 510 within insert 516.

[0218] In an alternative embodiment, a biasing device (not shown) may be provided to bias the locking member 518 away from its locked position, i.e., to move the member 518 downwardly along the inclined surface 502b to the unlocked position. Alternatively, a biasing device (not shown) may be provided to bias the locking member 518 from its unlocked position, i.e., to move the member 518 upwardly along the inclined surface 502b to the locked position.

[0219] exist Fig.23 510 is shown in an example of a striker bolt assembly 510 in a selected position. In this example, locking member 518 is also shown in a locked position relative to housing 512. In the selected position, striker bolt assembly 510 is secured by locking member 518 in a position where flange 512c is spaced apart from striker body 502. In this position, striker bolt 506 (shown in an extended position) is able to be moved more easily than when striker bolt assembly 510 is positioned closer to body 502 (e.g., as shown in FIG. 510 ). Fig. 20 502 (shown) extends further from the bump body 502 (in its extended position). Fig.23The location of the proximal end 506b of the striker bolt 506 is shown as an example of a desired strike distance in order to latch (ie, secure) the striker assembly to the latch assembly.

[0220] Advantageously, adjusting the strike distance, ie, the position of the housing 512 relative to the body 502, allows the striker assembly 500 and the latch assembly 200 to engage, ie, latch together, across gate gaps of varying sizes.
