A door assembly with an automatic misalignment accommodating finger guard comprising a door panel assembly having a panel member having an edge space and a door edge defining member including an inner portion configured to be positioned in an operative relation within the space by a relative longitudinal movement with respect to the panel member. A longitudinal position determining member is detachably fixed to the door edge defining member in a position to extend within a longitudinal position determining opening in the elongated panel member. A spring system is provided which acts between the door edge defining member and the panel member to resiliently bias the door edge defining member into a longitudinally determined limiting position. The door edge defining member and the spring system cooperate to enable the latter to be moved against the bias of the spring system angularly and/or translationally inwardly within the space in response to the engagement of the defined elongated door edge thereof with a closing surface during movement of the door panel assembly into the closed position to thereby automatically accommodate misalignment with the closing surface or with an object, such as a finger or the like, inadvertently disposed between the closing surface and the defined elongated door edge during movement of the door panel assembly into the closed position to thereby serve as a finger guard. The position determining member is configured and positioned to accommodate the angularly inward and/or translationally inward movement of the door edge defining member with respect to the panel member while maintaining the door panel assembly substantially in the determined longitudinal position thereof.

Door with automatic misalignment accommodating finger guard

A cylindrical lockset (20) includes an inside subassembly (22) and an outside subassembly (24) which are assembled with a door (208). Each subassembly (22, 24) includes a liner (26, 36), a rose (28, 38) and a lever (30, 40). A chassis assembly (58) includes a pair of sleeves (66, 68), a pair of spring plates (146, 192), a pair of torsion springs (166, 194), a cap (172), a case (182) and a retractor (70) which is coupled to the latchbolt (46). Upon operation of either of the levers (30, 40) from a non-operated or home position, the latchbolt (46) is retracted and the associated one of the springs (166, 194) is tensioned so that, upon release of the levers, the springs return the levers to the home position.

Cylindrical lockset

A cylinder lockset (30) includes a chassis assembly (72) with sleeves (80) and (81). A pair of liners (36) and (48) are mounted on sleeves (80) and (81), respectively, and facilitate attachment of chassis assembly (72) with a door (260). A pair of spring cassettes (38) are mounted on sleeves (80) and (82). A pair of levers (42) and (54) are mounted on the sleeves (80) and (82), respectively, and operate cassettes (38) directly for spring return of the levers upon release thereof. A pair of posts (388) and (390) are mounted on liner 48 and are formed with score locator lines (412), (414) and (416) to locate the liner relative to a housing (74) of assembly (72). Liner (36) is formed with four mounting holes (356), (358), (360) and (362) which facilitate use of the liner with either a lefthand or right-hand door mode.
