An adjustable hinge has a first leaf and an adjustable leaf mounting assembly which includes a second leaf, a bracket, a cam and an adjusting screw. The second leaf is mounted on the bracket and has one end extending beyond the bracket and pivotally engaged with the first leaf. The cam is rotatably mounted on the bracket and cooperates with a cam follower surface on the second leaf. The adjusting screw has a shank threadably engaged in the second leaf intermediate its ends and has its free end abutting the bracket. In operation, the rotation of the adjusting screw pivots the one end of the second leaf relative to the bracket and the rotation of the cam moves the second leaf vertically relative to the bracket.

An apparatus for providing an electrical transmission path in a door lock to an electrical lock operating system from an electrical contact pin protruding axially from a pin tower of an insulated key cylinder having an electronic touch button for a front face, the door lock having an outside spindle operably engaged with a door handle containing the insulated key cylinder, includes an insulated contact ring surrounding the spindle and having an electrically conductive pad on a portion of its outwardly facing surface, which contacts the electrical contact pin when the door handle is in its parked position, and a cable connected to the conductive pad and extending through the non-moving part of the door lock to the controlling electronics of the lock.

A pocket door latch assembly has a housing with a latch arm pivotally mounted therewithin. The latch arm has a latch nose at one end and an inverted generally V-shaped slot adjacent its other end, and the arm is pivotable between a first position wherein it is entirely within the housing and a second position wherein the latch nose extends outwardly of the housing. An actuator has a portion slidable within the slot between a first position adjacent the one end of the arm and a second position spaced from the one end to pivot the latch arm between its first and second positions. The actuating means is manipulable outwardly of the housing to slide the slidable portion of the actuating means within the slot between its first and second positions, thereby pivoting the latch arm between its positions.

A hinge includes a first hinge leaf with two axially spaced knuckles and a second hinge leaf having a knuckle extending between and axially aligned with the knuckles of the first hinge leaf. The knuckles of the two hinge leaves have bores extending therethrough and that of the second leaf has a counterbore at each end thereof. Seated in the bore at each end of the second leaf knuckle is a bearing assembly including a collar portion seated in the counterbore. The bushing has an axial bore extending therethrough and a counterbore at its outer end. A metallic thrust bearing has a generally axially extending body portion disposed in the counterbore of the bushing, and a peripheral collar at the outer end overlies the outer end of the bushing and provides a thrust bearing surface for the adjacent knuckle of the first hinge leaf. In one embodiment, the bushing bore has channels to allow flow of electroplating solution if the hinge is electroplated after assembly.

A cylindrical lock assembly (20) includes an inside subassembly (22) and an outside subassembly (24) which are assembled with a door (326). Each subassembly (22,24) includes a rose liner (26,38), a return spring cassette (28,40), a rose (30,42), a lever (32,46) and a lever insert (34,48). The inside subassembly (22) also includes a turn button (36) and the outside subassembly (24) includes a cylinder lock (44). Cylinder lock (44) includes a plug (114) within a shell (112). A rib (122) for supporting tumbler pins (428) is formed with the shell. An identifier actuator (456) is depressed by a tailpiece (116) when a turn button (36) is operated to lock the assembly (20). When the actuator (456) is depressed, an identifier pin (436) is moved within the plug (114) and extends partially from the front of the plug to signify that the assembly (20) has been locked from the inside.

A snap-in hinge assembly for mounting doors on door frames comprises a hinge with one of its leaves providing a plurality of spaced recesses, and a hinge leaf receiving receptacle mounted in a recess. The receptacle includes a reinforcing member having mounting portions secured to the frame or door and a seat portion defining a channel of a width dimensioned to receive the length of the hinge leaf. The seat portion has latch receiving recesses therein cooperatively positioned relative to the spaced recesses in the hinge leaf and a plurality of latch elements are disposed in the latch receiving recesses. Biasing elements bias the latch elements outwardly of the latch receiving recesses into the channel and they seat in the hinge leaf recesses when the hinge leaf is inserted thereinto. Thus, the door with one hinge leaf secured thereinto may be mounted on the door frame by inserting and sliding the hinge leaves into the channels of the receptacles to engage the latch elements in their recesses.

A fire-retardant pivoted door assembly with fire activated latching members includes a metal door frame having jambs and a header in which a fire-retardant door is mounted by a hinge assembly with a lower temperature resistance that the door and frame. Fire actuated latch bolt assemblies in the door are spaced vertically along the hinge side of the door, and include a housing providing an elongated cavity opening at the edge of the door. A latch bolt is slidably seated in the cavity and is biased towards the opening of the cavity. A fusible closure extends across the opening of the cavity and retains the latch bolt against the biasing pressure, and the hinge jamb has a spaced recess formed therein to receive the latch bolt upon melting of the fusible closure.

A door latch assembly 10 includes a rack 102 which is moved upon depression of a thumbpiece 12. Movement of the rack 102 results in rotation of an enmeshed pinion 136 and an assembled spindle 152. As the spindle 152 rotates, a latch 26 is moved from a latched position to an unlatched position to thereby permit opening of a door 20 on which the door latch assembly is mounted. When it is desired to lock the door 20, a key-operated lock cylinder 16 is operated to place into motion facilities for moving the rack 102 into a disabled poisition whereafter depression of the thumbpiece 12 will not result in movement of the rack. As the rack 102 is moved to the disabled position, teeth 104 of the rack remain enmeshed with teeth 138 of pinion 136. When the rack 102 is again moved to the enabled positon, the teeth 104 and 138 remain enmeshed and thereby avoid any deleterious reactions had they been separated upon disablement of the rack 102 and re-enmeshed upon enablement thereof.
