Convertible cylinder lock

A convertible cylinder lock handle having a channel sized to receive a lock cylinder and a slot in spacial communication with said channel, and means insertable into said handle slot for preventing substantial axial movement of a cylinder mounted within said channel in one slot mounted orientation and for permitting limited cylinder axial movement of the cylinder in another slot mounted orientation, said means comprising a bolt lock plate that has two stops spaced apart a distance to receive and entrap a spring biased bolt of the lock cylinder therebetween with one of said stops having a ramped surface facing away from the other stop over which the cylinder bolt may be cammed.

A convertible cylinder lock handle comprising a hub, a handle extending from said hub, a drive shaft extending from said hub along an axis of handle rotation, and wherein said hub has a channel sized to receive a lock cylinder and a slot that extends along and spacially communicates with said channel sized to receive a spring loaded lock cylinder bolt, and a bolt lock plate sized to be received in reversible orientations within said slot which has two stops spaced apart a distance to receive and entrap the cylinder bolt therebetween with one of said stops having a ramp for camming engagement with the spring loaded cylinder bolt, whereby in one lock plate orientation the bolt is locked out of the lock plate and in its reversed orientation the lock plate receives and entraps the bolt.

A pop out cylinder lock handle convertible between stationary and push to lock configurations, and with the pop out cylinder lock handle having a hub, a handle extending from said hub, a drive shaft extending from said hub along an axis of handle rotation, and wherein said hub has a channel with a spiral ramp sized to receive a lock cylinder and a slot that extends along and spacially communicates with said channel sized to receive a spring loaded lock cylinder bolt, and a bolt lock plate sized to be received in reversible orientations within said slot which has two stops spaced apart a distance to receive and entrap the cylinder bolt therebetween with one of said stops having a stop ramp for camming engagement with the spring loaded cylinder bolt, whereby the lock cylinder may be removed from the handle hub with a spanner tool by rotating the cylinder lock in a locked condition with the hub channel ramp camming the bolt to an unlocked position and drawing the lock cylinder out with a key to expose the bolt lock plate and then reversing the orientation of the plate.
