ABSTRACT:
A sealing cap is provided for a lock having a key receiving passage therein. The sealing cap comprises a sealing member which overlies the passage. The sealing member has a first slit therein extending from the outer surface of the sealing member to about the midline thereof at a first oblique angle. A second slit extends from the midline of the member to the inner surface of the member at a second oblique angle. The size of the slits, position of the openings at the ends of the slits and the midline, and the flexibility of the walls of the slits with respect to each other are adapted to seal the passage and permit the insertion of a key through the slits into the passage. The sealing member is sealingly mounted on the lock for rotation in unison with the key. Optionally, a key skirt is also provided which sealingly fits on the key and sealingly mates with the outer surface of the sealing member while the key is in the slit and the key receiving passage. The sealing cap of this invention provides a way for sealing out moisture, dust and other contaminants from the key receiving passage and lock mechanism, which contaminants usually result in the destruction of the lock mechanism and its function.
