摘要： An electromagnetic lock assembly has longitudinally extending interlocking protrusions and recesses in the magnet and magnet housing surfaces. This permits longitudinal movement of the magnet within the housing, but prevents lifting of the magnet out of the housing. End caps and an electronic circuitry cover clamp the magnet longitudinally within the housing and provide the mounting bolt brackets. An armature, providing for distribution of separating forces, reduces bending tendencies in the armature contact plate and thereby increases the effective separation load bearing capability of the lock assembly.

摘要： The universal assembly comprises components and parts interchangeable between, for being common to, a top latch and a bottom latch in vertical-rod exit devices. Simply by adding a few discrete parts to the assembly, the same becomes, selectively, a top latch or a bottom latch, The top latch, and the bottom latch, comprise the universal assembly to which the respective, discrete parts have been added. The assembly, and the latches have a rotatable input member with must be rotated to enable retraction of a latch bolt, and a limb operative to block retraction of a latch bolt if the input member is not rotated.

摘要： The device comprises a latching assembly enclosed within, and translatable relative to, a centercase housing; the housing is mounted on a chassis. The device is adapted for cooperative engagement with a locking cylinder, for actuating the latching assembly, and for operation of a thumbpiece lift, by an ancillary, external, trim linkage, for translating the latching assembly. The latching device has a master, locking cylinder cam or dowel, the latter having a removable screw, which (through a locking cylinder) either operates a night-latch cam plate, to translate the latching assembly or, upon removal of the screw, allows the cam or dowel to translate a tumbler which, in turn, frees a thumbpiece lift, for operation (then) of the latching assembly by the lift, instead of by the cam plate. Accordingly, with the drive screw in place, the external, operating trim linkage can not operate the device; it must be unlatched, externally, by a key in the locking cylinder. With the drive screw removed, the use of a key in the locking cylinder will not unlatch the device, rather, in this circumstance, key-operation of the locking cylinder will enable the external trim linkage to unlatch the device, and such key-operation (with the drive screw removed) will also disable the trim linkage operation of the device, selectively.
摘要翻译： 该装置包括封闭组件，其相对于中心壳体封闭并且可相对于中心壳体壳体平移; 外壳安装在底盘上。 该装置适于与锁定圆柱体协作接合，用于致动闩锁组件，以及用于通过辅助外部装饰连杆机构操作拇指引导件，用于平移闩锁组件。 锁定装置具有主锁紧缸凸轮或销钉，后者具有可拆卸的螺钉，（通过锁紧缸）操作夜间闩锁凸轮板以平移闩锁组件，或者在拆卸螺钉时允许 凸轮或定位销翻转一个翻转开关，而翻转开关反过来又释放了一个拇指提升器，用于由升降机而不是由凸轮板操作（然后）闩锁组件。 因此，在驱动螺钉就位的情况下，外部操作装置联动装置不能操作; 必须通过锁定缸中的钥匙在外部解锁。 拆卸驱动螺丝后，使用锁定缸中的钥匙不会使装置松开，而在这种情况下，锁紧缸的关键操作将使外部装饰联动装置能够松开装置，而这种按键操作 （拆下驱动螺钉）也将有选择地禁用装置的调整联动操作。

摘要： An apparatus for operating a door-latching and -unlatching device includes a thumbturn, a barrel cam, a shaft for coupling the thumbturn to the barrel cam to cause rotation of the barrel cam in response to movement of the thumbturn, a follower for the barrel cam and apparatus attaching the follower to the latch bolt to cause the latch bolt to move in response to actuation of the barrel cam. The illustrative barrel cam includes two generally diametrically opposed cam lobes such that rotation of the thumbturn either clockwise or counter-clockwise retracts the latch bolt. The follower includes a bar which lies against the cam surface of the barrel cam, and the latch bolt moving apparatus includes an actuator arm which is pivotally mounted adjacent one of its ends, the follower pin being mounted intermediate the actuator arm ends, the follower pin being supported adjacent the barrel cam, and the actuator arm further including a roller retractor actuator adjacent its other end.

摘要： A latch and actuator assembly, primarily intended for use as a panic exit device, in which a push bar substantially spanning the width of a hinged closure is mounted for bodily rectilinear movement in the closure-opening direction and perpendicularly toward the closure, one or more toggle-like linkages being interposed between the push bar and an actuator, mounted for movement transversely of the closure and operatively connected to a movable latch bolt, the actuator being biased toward boltprojected position and being moved to bolt-retracted position by the elongation of the toggle-like linkages upon such movement of the push bar. In one form of the invention, the apices of two such toggle-like linkages are joined by a rigid stretcher; while in another and preferred form, a guide lip engages the roller at the apex of each toggle to confine that roller in contact with the inner surface of the push bar.

摘要： Automatic flush bolt latch means for one of a mating pair of doors, so constructed and arranged that, when both doors are closed, said one door is affirmatively locked, that when the other door is even slightly opened said one door will remain latched but with its latch means readily retractable by the application of gentle opening force to said one door, and that said latch means, when once retracted, will remain so until both doors again assume closed positions, no matter which door closes first, whereupon said one door will again be affirmatively locked for so long as said other door remains closed.

摘要： A lock assembly for use with a door movably coupled to a door frame. The lock assembly includes a housing, a control member, a latchbolt, and a locking member. The control member is movably coupled to the housing from a locked position to an unlocked position to allow the door to move with respect to the door frame. The latchbolt moves with respect to the housing in a first direction and a second direction. The locking member is configured for engagement with the control member to move the locking member with respect to the housing into and out of an engaged position with respect to the latchbolt. The locking member includes a surface that contacts the latchbolt when the locking member is in the engaged position to substantially prevent movement of the latchbolt in the first and second directions.
