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： A door lever assembly having a locked and an unlocked position includes a trim housing and a lever handle and cam rotatably connected to the trim housing. A rotatable shaft extends between the lever handle and the cam, with the shaft defining a connection groove therethrough to provide access to a shaft interior. The shaft interior is configured to accept a pin for connecting the cam and the shaft. This pin can be wedgably disconnected following controlled slippage of frictional wedge surfaces in response to excessive force applied to rotate 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 supporting a stop plate. A cam is operably connected to the lever handle and 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. A lift arm is operably connected to vertical rods of the door latch assembly and an over-ride spring is connected between the slider and the lift arm. The over-ride spring transmits motion of the slider to the lift arm to lift the lift arm and the connected vertical rods when the door latch assembly is in an unlocked position. The over-ride spring compresses in response to slider movement when the blocking slide is positioned to block movement of the lift arm when the door latch assembly is in its locked position, preventing damage to components of the door lever assembly. In an unlocked position, a pivot rotates to control contact between the slider and the stop plate.

摘要： A fluid shear coupling apparatus includes a driving member comprising a rotor mounted to a shaft and defining several annular ridges and grooves. A driven member including a bearing housing is mounted to the shaft. A cover secured at the perimeter to the bearing housing has a disc-shaped portion defining several annular ridges and grooves positioned complementary with the ridges and grooves of the rotor. A shear fluid therebetween provides variable coupling according to the proportion of fluid in the reservoir vis a vis the working chamber defined by the complementary grooves and ridges. A temperature responsive valve cooperates with a modulation ramp encasing the valve end to provide a fluid control orifice which varies in size and radial location in response to temperature, thereby providing temperature modulation of the amount of shear fluid in the working chamber, and consequently, the degree of coupling.

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： 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.
