<p>A key and card combination formed from molded plastic material comprises a key-shaped recess socket in the plane of the card, a key being separably located in the recess socket and formed in one piece with the card, and integral multi-directional hinge structure formed from the same material as the key and card and integrally connects an edge of a head end of the key to an edge of the card in the socket. The hinge adapts the key to be swung out of and swung back into the plane of the card. When the key is swung out of the plane of the card, the key is enabled to be twisted in various directions relative to the card on and about the hinge, laterally or about the axis of the hinge. In a preferred construction, the hinge structure comprises a rod-shaped elongated element.</p> |
