Abstract: A lock mechanism has a locked condition and an unlocked condition and includes a housing. The lock mechanism also includes a latch that extends from the housing and has an extended position and a retracted position. The lock further includes a biasing member for biasing the latch to the extended position. The lock mechanism further yet includes a means for transferring an operator input motion to move the latch to the retracted position in the unlocked condition. The means for transferring an operator input motion includes uncoupling the operator input motion from the latch in the locked condition. The means for transferring also includes a locking driver and a locker. The locking driver includes a first surface and a second surface and the locker includes a biasing member for biasing the locker toward at least one of the first and second surfaces.

Abstract: A lock actuation assembly for use in a lock chassis. The lock actuation assembly comprises a core and a driver. The core includes a tubular portion positionable in the lock chassis and including a passage therethrough. A flange extends through the tubular portion and is biasable to a position in which a driver engaging portion is within the passage and a projection engaging portion is within the tubular portion's extent. The driver includes a shaft configured to be received within the passage to operably engage the lock chassis' drive system and to engage the flange driver engaging portion such that the projection engaging portion is forced into engagement with a projection extending into the lock chassis core-receiving chamber.

Abstract: A knob catch for securing a knob or lever to the driving spindle of a door lock. The knob catch is constructed of a base with a centered odd shaped hole. The hole is made in such a way that the knob or lever cannot be removed when the locking device is in the locked position using a key operated cylinder with a flat locking bar. A tongue portion of the knob catch rises above the base and fits into the knob or lever and keeps the knob or lever from being removed. In the front side of this tongue is an angular surface which permits the knob or lever to be slid over the top of the knob catch until the knob catch tongue and an aperture in the knob or lever align allowing the tongue to be spring biased into the aperture to secure the knob or lever. There are two springs attached to the knob catch to bias the tongue into engagement with the knob or lever aperture.
