Abstract
A key holder which has a pair of shells for enclosing the keys which are connected together by a spring-loaded locking hinge. The keys are connected to the shells by at least one arm attached to one of the shells. The keys can be stacked on top of each other inside the key holder. The spring-loaded locking hinge generally holds the shells in a closed position relative to each other. This is accomplished by a knob on one part of the hinge which engages with a notch on another part inside the hinge. A spring kept in torsion and compression tends to urge the shells open so that when a button on the end of the hinge is pressed, the knob disengages the notch and the spring causes the shells to open.
