Abstract

The invention relates to a push-in-plunger-lock and housing-cylinder that facilitates an easy removal and installation of the push-in-plunger-lock as it attaches to a lockable device. Normally the push-in-plunger-lock can be mounted to a lockable device using two flanges with holes or threads on the lock being secured in place with a locknut ring. In certain particular applications of using the push-in-plunger-lock there is no suitable application to mount the lock other than metal welding the push-in-plunger-lock to the lockable device. One of these particular applications is mounting the push-in-plunger-lock on a ratchet chain binder to block the use of the U-pawl preventing the normal operational removal of the ratchet chain binder from a chain. The invention provides a housing-cylinder to insert the push-in-plunger-lock into while securing the lock in place with a pin. The pin can only be removed when the push-in-plunger-lock is in the unlocked position. The invention allows the push-in-plunger-lock to be easily changed and matched to keyed alike other push-in-plunger-locks instead of re-keying the push-in-plunger-locks or allowing the replacing of a defective push-in-plunger-lock that would involve grinding the defective push-in-plunger-lock from the lockable device and metal welding a replacement push-in-plunger-lock onto the lockable device.
