Abstract: The improved padlock and protective cover assembly includes a flexible resilient cover of natural or elastomeric material releasably disposed around the body of a padlock. The hasp, including its rungs, project up and out of the top of the cover. The cover top is removable from the lower portion of the cover and fits snugly around the rungs to prevent water from contacting the padlock body. That body is disposed snugly within an open-topped insert, the insert also fitting snugly within the lower portion of the cover. Both the insert bottom and the bottom of the lower portion of the cover define an opening up through which a key can be inserted into the lock body to release the hasp. The opening in the cover lower portion bottom is normally closed but can be flexed open. In one embodiment that bottom is specially configured as an upwardly projecting arc to facilitate squeezing the opposite sides of the bottom toward each other to flex open the keyhole.

Abstract: The assembly includes a lock with a main lock body having a bottom keyhole and an inverted u-shaped double rung top hasp connected to the top of the main body and extending upwardly therefrom. The assembly also includes a flexible, resilient, elastomeric protective lock cover removably enclosing and sealing the lock body against the elements. The cover is in two pieces. It includes a bottom portion extending over the lower sides of the lock body and continuing below the lock body. The bottom portion has opposed sides and a tapered bottom defining an openable closed slit through which, when opened, by squeezing opposed sides toward each other, the keyhole can be reached by a key. The cover also includes an upper cap having a top and interconnected depending sides. The inner surfaces of the cap sides bear a circumferential groove engageable with and of smaller diameter than the base of a circumferential bead with sloping top and bottom on the outer surface of the sides of the bottom portion.

Abstract: The assembly includes a lock with top hasp and botton keyhole and a flexible, resilient, stretchable covering forming a protective closed casing around the main body of the lock and up through which the hasp protrudes. The casing extends below the lock body and includes a bottom normally closed slit automatically openable by squeezing opposed sides of the lower portion of the casing toward each other at opposite ends of the slit, in order to permit a key to be inserted in the keyhole. The area around the slit can have diverging moisture diverting lips or a single protective overlying lip. Dessicant may be disposed in containers in the casing and the top of the casing can have upstanding collars which tightly grip the hasp. A slot covered with a flap may extend therebetween for removal of the lock from the casing. The casing can be made from natural or synthetic elastomer such as polyurethane capable of retaining its flexibility over a wide temperature range.
