摘要： An apparatus for providing an electrical connection from a power source, through a stationary door frame, into a door to connect to door-mounted electrically-operated hardware, includes an electrical junction box installed in a mortise cavity in the door frame adjacent to a similar electrical junction box installed in a mortise cavity in an edge of the door. The junction boxes are adjacent each other when the door is in a closed position; and a housing is installed in each junction box, each housing having a longitudinal slot in a face plate thereof of a length substantially equal to the length of the junction box. A cover plate is longitudinally slidably engaged in grooved fingers on a rear surface of the face plate, the cover plate having a substantially circular hole. A hollow tube, having an elbow swivelably mounted on each end, has one elbow swivelably engaged in the substantially circular hole of the cover plate of the housing mounted in the door frame and the other elbow swivelably engaged in the substantially circular cover plate of the housing mounted in the door. A conductor cable connected to a power source, in the junction box mounted in the door frame, extends through the elbows and the hollow tube into the junction box mounted in the door, and connects to leads to door hardware mounted in or on the door.

摘要： An electromagnetic coil for use in a doorholder for retaining a door in an open position by magnetic interaction with an armature secured to the door includes a coil of wire for surrounding a core within a cup. A power control circuit including a resistor circuit, controls electrical power supplied to the coil, the power control circuit being mounted on a circuit board situated between the coil rear surface and the cup bottom. The resistor circuit being situated in sufficiently close proximity to the cup bottom for transfer of heat from the resistor circuit to the cup. The power control circuit also includes a low resistance circuit coupled to the resistor circuit, the low resistance circuit including a fusible link, the fusible link being selected to carry current when the power input terminals are coupled to a lower voltage power source and to stop carrying current when the power input terminals are coupled to a higher voltage power source.

摘要： A door lever assembly having a locked and an unlocked position includes a trim housing and a lever handle rotatably connected to the trim housing. A cam is rotatably connected to the trim housing, and a pin mechanism is movably positionable to connect with the lever handle. A slider is attached for movement in the trim housing in response to rotation of the cam, anda lift arm is connected to the slider. The lift arm is rigidly movable with the slider when the door lever assembly is in its unlocked position and the lever handle is rotated. When the door lever assembly is in its locked position, the lift arm pivots toward the cam to disengage the pin mechanism from its connection between the lever handle and the cam.

摘要： A door lever assembly for disengaging an unlocked latch of a lockable door latch assembly includes a lever handle rotatably connected to a trim housing and a cam operably connected to the lever handle. The cam is positioned to rotate in response to rotation of the lever handle, converting its rotational movement to linear movement of a movable slider positioned adjacent to the cam. An electrically activated block arm is positionable to prevent movement of the movable slider, effectively locking the door lever assembly.

摘要： A latch assembly for a fire door having a pushpad for emergency exit is described. The pushpad is connected to a rod to transfer motion of the pushpad to the latch assembly. The latch assembly includes a platform attached to the fire door, a linkage assembly attached between the rod and a latch bolt, and a deadlock arm assembly attached to the platform. The deadlock arm assembly is movable between a first position to block movement of the linkage assembly and a second position to allow movement of the linkage assembly. A fire fuse assembly is also attached to the linkage assembly to move the deadlock arm assembly out of its first position blocking movement of the linkage assembly at normal room temperature. The fire fuse assembly is configured to melt at temperatures substantially above normal room temperature to prevent engagement between the fire fuse assembly and the deadlock arm assembly, effectively preventing movement of the deadlock arm assembly out of its first position blocking movement of the linkage assembly in response to movement of the rod.

摘要： An adjustable overhead mounted door holder assembly for attachment between a door jamb and a door to hold the door in an open position includes a jamb bracket attached to the door jamb and a jamb arm pivotally attached to the jamb bracket. A channel assembly having a longitudinally extending channel is attached to the door, and a spring assisted assembly holds the door in an open position assisted by frictional force. The amount of friction is adjustable by altering a rotational position of an eccentric cam.

摘要： A mechanism for dogging a door latch assembly of a panic exit device having a retractible door latch biased to move outward from the door latch assembly, with inward movement of the door latch being activated by a push bar, includes a mechanism for holding a key cylinder positioned adjacent to the door latch assembly. A catch mechanism linked to the door latch is configured to move as the door latch is retracted, and a arm is pivotably mounted adjacent to the key cylinder holding mechanism. The arm is configured to retain the catch mechanism, with the door latch being prevented from outwardly moving with respect to the door latch assembly. When a key cylinder having an attached sweep arm is rotated, the sweep arm can alternatively rotate to engage the catch mechanism when a key is turned in the key cylinder, dogging the door latch assembly, or undog the catch mechanism from the arm by sweeping around to break the attachment between the arm and catch mechanism, allowing the door latch to move from its retracted position to its normally biased outward position with respect to the door latch assembly.

摘要： An armature assembly for use with an electromagnetic door holder has a ball stud pivotably connected at one end to a mounting bracket and at the other end to an armature plate. The mounting bracket is mounted on a first structural member, a mounting body is secured to the bracket and connects with the ball stud, and the armature plate coacts with and is held against an electromagnet which is mounted on a second structural member. The pivotable attachments at both ends of the ball stud provide an almost universal adjustability to the armature assembly and, thus, accomodate complex misalignments between the first and second structural surfaces.

摘要： The pinion is of two-piece construction, the two pieces being identical and nestably mated to define a recess, therebetween, which is interrupted by abutments, and which confines an abutment-engaging pin. Each piece has a plurality of teeth projecting therefrom, and the pieces are so mated that the teeth pluralities project form opposite sides of the formed pinion. A generally U-shaped rack, having teeth formed on the confronting surfaces of the parallel limbs thereof, is in mesh with the pinion, and the pin penetrates an input shaft upon which the pinion is mounted. As the shaft is turned in one direction, the pin drivingly engages the abutments of only one pinion piece, to cause the teeth of the latter to drive the rack in one, given direction. Too, if the shaft is turned in the opposite direction, the pin engages the abutments of only the other pinion piece, to cause its teeth to drive the rack in the same, one, given direction.

摘要： The presence of persons in a space is sensed with the aid of ultrasonic pulses which are sent out into the space when echoes of such ultrasonic pulses are received. Echoes attributable to the floor or to parts of a door in the space are timed out, and a remainder of such echoes is employed for sensing persons in the space. For example, sliding or revolving doors may be controlled and operated with the aid of such ultrasonic echoes, and limited access to secured areas may be provided thereby.
