A nested paddle lock assembly comprises inside and outside pan assemblies mounted in alignment with one another on a door and respectively having inside and outside selectively pivotal paddle handles, slide means in said door selectively linearly actuated by either handle when pulled, pivotal lever means pivoted by said linearly moving slide means upon handle actuation to unlatch said door, spring means to return the pivotal lever means, slide means and handles to their respective normally closed positions and lock means selectively actuated from inside or outside the door either to lock the door by obstructing slide means movement or to unlock the door by allowing slide means movement.

Nested paddle lock assembly

The rotary paddle latch of the present invention has a latched position, an intermediate safety position and an unlatched position and includes an assembly for locking the external rotary paddle while permitting an optional internal handle to override the lock to move the latch to its unlatched position. The rotary paddle latch assembly includes a pivotally mounted latch bar pivotally actuated by the external rotary paddle, a spring biased, pivotally mounted tripping pawl selectively pivotally actuated by the latch bar or by the optional internal handle, a pivotally mounted stepped cam having an abutment surface engaged by said tripping pawl, and a spring biased, pivotally mounted latch plate having a throat therein for receiving a striker bar. The latch plate includes a cam follower riding along the stepped cam when the tripping pawl is moved to allow pivotal movement of the latch plate between the three latch positions. The rotary paddle latch includes a support bracket for mounting the latch plate and cam and a shield mounted on said bracket including a groove cooperating with the latch plate throat to surround the striker bar in the latched and intermediate positions. All components of the latch are universally configured for left or right hand doors.

Rotary paddle latch

A door lock includes a plurality of latch bolt assemblies that are mountable on a door at spaced locations about the periphery of the door, an operating mechanism that is flush-mountable on the door at a central location, and elongate linkage elements for interconnecting the operating mechanism with the latch bolt assemblies to enable the operating mechanism to concurrently operate the latch bolt assemblies. The operating mechanism includes a pan-shaped housing, a paddle handle that is mounted on the housing for pivotal movement between a nested position and an extended position, a slide that is track-mounted for sliding movement relative to the housing between first and second positions, a pair of operating arms that are and are pivotally connected to the housing for movement between latched and unlatched positions in response to movement of the slide, and a detent that is interposed between the housing and the slide for assisting to releasably retain the slide in its first and second positions, and to releasably retain the arms in their latched and unlatched positions.

Combined latch operating handle and handle housing

A cabinet lock has an elongate body. An operating handle is connected to the body for pivotal movement about an axis that extends transverse to the length of the body. The body slidably mounts (1) a spring-projected latch bolt for linear movement along a path of travel that substantially parallels the axis of pivotal movement of the handle, and (2) an operating member for linear movement along a path of travel that substantially parallels the length of the body. The handle has a formation that drivingly engages the operating member for moving the operating member from a latched position to an unlatched position in response to pivotal movement of the handle from a nested position to an operating position. A key cylinder is rotatably mounted on the housing and carries a stop formation that is operable (1) when the key cylinder is in an unlocked position to permit sliding movement of the operating member along the body in response to movement of the operating handle from its nested to its operating position, and (2) when the key cylinder is in a locked position to retain the operating member in its latched position and to retain the handle in its nested position. The slide bolt retracts from its normally projected position in response to movement of the operating member from its latched to its unlatched position.
