Abstract: A lockset is provided for use in a door. The lockset includes a lock core, a body mounted on the door, a door handle mounted on the body, a locking-unlocking mechanism, and a throw member mounted for rotation with the lock core. The locking-unlocking mechanism locks and unlocks the lockset in response to rotation of the key within the lock core. The throw member includes an outer perimeter edge, a blade extending toward the locking-unlocking mechanism, and a channel extending around the outer perimeter edge. The body also includes a pin that extends into the channel so that when a key is rotated in the lock core, the lock core and throw member rotate relative to the pin. This rotation causes the throw member to move from an inactive position disengaged from the locking-unlocking mechanism to an active position where the blade engages the locking-unlocking mechanism.

Abstract: A button assembly for a button-actuated lockset having a locking mechanism. The button assembly includes a button member and an actuator mechanism such as a locking bar. A rib is provided on the button member to retain the button member on the locking bar yet permit rotation of the button member relative to the locking bar. The button assembly can further include a button cover provided with an engaging mechanism to allow the button cover to be press-fit on the button member.
