  • Patent number: 4289003
    Abstract: A key case for holding and enclosing one or more keys in a more orderly, compact manner while allowing ease of selection, freedom of use, and ease of restorage after use. This is accomplished using a single, triangularly shaped key-holder, which holds all the keys in the key case, and attaching it at one corner to the body of the key case by a double-hinge, universal pivot mechanism, with the keys being stored in face-to-face engagement in an "upside-down" disposition (FIG. 3). The triangular key holder in storage disposition allows for a reduction in size of the key case and further incorporates semicircular corners at its base to facilitate control and separation of the keys while a key is being put in use (FIG. 1).
