Abstract

This relates to a key cover for covering the head of a key. In one embodiment, the key cover is formed in two pieces, a cover member and a plug. In a second embodiment, the cover member and plug are pivotally connected. 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 body having a cavity therein for receiving a key head, said body also having an opening into the cavity through one end thereof, said opening being configured to receive a key head, and a slot at an opposite end thereof in communication with the cavity for receiving a key blade, means pivotally mounting a plug to the body adjacent to the opening, said plug being configured to fit snugly in the opening and be pivoted into the opening and means for securing the plug in the opening.

2. A key cover according to claim 1 wherein said pivotably mounting means is a hinge.

3. A key cover according to claim 2 wherein the hinge is a thin strap having one end connected to the plug and another end connected to the body.

4. A key cover according to claim 3 wherein the hinge is integrally formed with the plug and the body.

5. A key cover according to claim 3 wherein the plug, hinge and body are formed of a one piece plastic molding.

6. A key cover according to claim 1 wherein said cover member and said plug have aligned openings for receiving a key retainer.

7. 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.

8. A key cover according to claim 7 wherein said plug has a lower edge profile generally matching an outline of an upper edge of a head of an intended key.

9. 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.

10. A key cover according to claim 1 wherein said cover member and said plug have aligned matching upper edges.

11. A key cover according to claim 1 wherein said securing means includes a tab on one of said body and said plug, and a seat on the other of said body and said plug, said tab being receivable in the seat when the plug is received within the opening.

12. A key cover according to claim 11 wherein the tab is disposed on the plug and the seat is disposed on the body.

13. A key cover according to claim 12 wherein the tab is a boss projecting from the plug and the seat is formed by an aperture through a wall of the body.

14. A key cover for a key of the type including an elongated blade and a wider head, said key cover comprising:

a body having a cavity therein for receiving a key head;

said body having an opening into the cavity through one end thereof;

a slot at an opposite end of said cavity from said opening in communication with the cavity, said slot being configured to receive a key blade;

a plug having a first portion configured to fit snugly within said opening, and a second portion configured to remain facing outwardly of the opening; and

a hinge connecting one of the first portion and the second portion to said body adjacent to the slot whereby said plug can be pivoted to fit the second portion snugly within said opening.

15. A key cover according to claim 14 wherein the opening has an end edge and the hinge extends from the end edge.

16. A key cover according to claim 14 wherein the body has an exterior surface contour adjacent to the opening, and the second surface contour of the body when the first portion is snugly fit within the opening.

17. A key cover according to claim 16 wherein the hinge has an exterior surface contour flush with the exterior surface contours of the body and the second portion, when the first portion is snugly fit within the opening.

18. A key cover according to claim 17, wherein the hinge is a living hinge formed of plastic.
