ABSTRACT:
A key case (10) consisting of a first cover (12) and a second cover (28) that enclose a first and a second sidemember (14,26) that have sandwiched between them a lower and an upper leaf spring (18,20). The springs control and maintain the retracted and extracted positions of an articulated first and second key (22,24). The keys have near their articulated points a straight receiving step (22B, 24B) and an angular stop (22C, 24C). The steps maintain the keys in a horizontal position and the stops maintain the keys at an angular position where each position is with respect to the horizontal plane of the key case (10). In a second configuration of the invention, two key cases (10) are joined at their sides to provide a key case with four keys. In either configuration when the keys are retracted, the key case (10) takes a very little space and its design prevents tearing or premature wearing of trouser pockets or purse linings.
