Abstract

This relates to a key cover for covering the head of a key. The key cover is formed in two pieces, a cover member and a plug. The cover member is provided with a cavity for receiving the key head with the blade of the key passing through a slot in the underside of the cover member. A plug is then readily insertable into the top of a cavity in overlying relation to the key head disposed within the cavity of the cover member and locked in place with the cover member. The interlock between the plug and the cover member is one wherein the plug cannot be readily removed unless the cover, for all practical purposes, is locked in place on the key. This permits the key cover to be individually applied to a key without materially disassociating the key from its respective lock.

Claims

1. A key cover for a key of the type including an elongated blade and a wider head, said key cover comprising a cover member having opposing walls defining in part a cavity for receiving a key head, one of said walls having a shoulder notch, said cover member further having an opening through one end thereof to the cavity, and a slot through an opposite end thereof to the cavity for receiving a key blade, and a plug receivable in said opening at said one end, said plug having remote faces and a projecting tab on at least one of said faces for engaging the shoulder notch to secure the plug in the opening.

2. A key cover according to claim 1 wherein said opposite end is of an axial extent and defines an end of said cavity of a configuration generally matching an outline of an intended key head adjacent its blade.

3. A key cover according to claim 1 wherein said plug has a lower edge profile generally matching an outline of an upper edge of a head of an intended key.

4. A key cover according to claim 1 wherein said cavity tapers in transverse depth from said one end towards said opposite end.

5. A key cover according to claim 1 wherein said cover member has walls separated by said cavity, and at least one of said walls has a key identification receiving opening therein.

6. A key cover according to claim 1 wherein both said cover member and said plug are of a molded plastic construction.

9. A key cover according to claim 8 wherein said opposite end is of an axial extent and defines an end of said cavity of a configuration generally matching an outline of an intended key head adjacent its blade.

10. A key cover according to claim 9 wherein said plug has a lower edge profile generally matching an outline of an upper edge of a head of an intended key.

11. A key cover according to claim 10 wherein said cavity tapers in transverse depth from said one end towards said opposite end.

12. A key cover according to claim 11 wherein said cover member has walls separated by said cavity, and at least one of said walls having a key identification receiving opening therein.

13. A key cover according to claim 12 wherein both said cover member and said plug are of a molded plastic construction.

14. A key cover according to claim 13 wherein said cover member and said plug have aligned matching upper edges.
