Abstract
Abstract A kit of interrelated protective components for safeguarding rim cylinder locks mounted in doors, such components including (1) a mounting sleeve that fits over a conventional cylinder lock as it extends through a door, (2) reinforcing plates that are seated on the inner side of the door adjacent to the deadbolt for the lock, and (3) adapter means for securing locks of different sizes snugly within the sleeve and flush with the outer side of the door. The sleeve includes an annular lip that fits against the outer side of the door, a substantially cylindrical body, bentover tabs with apertures therein to receive the elongated mounting screws that engage similar holes in the lock to retain the lock within the sleeve; and spaced ears that are bent into engagement with the rear face of the door to securely anchor the tube thereto. One reinforcing plate has an indented portion so that the second reinforcing plate can be seated therein; both plates have central apertures that enable the tongue of the cylinder lock to pass freely therethrough and screw holes to accomodate the pair of elongated mounting screws that hold the lock in position within the sleeve. The adapter means comprise an annular ring, a shim and a wedge that is forced into the ring to secure same to the body of the cylinder lock; such components enable locks having different sized front lips to be secured within the body of the mounting sleeve.
