ABSTRACT:
Key holder includes, in its most preferred embodiment, front and back covers with interlocking hinge appendages defining a transverse passageway inside which is located a swivel cartridge functioning both as a hinge pin and as a swivelling key attachment device. Swivel cartridge includes a casing, a swivel member located at least partially within the casing so as to be capable of rotation with respect to the casing and extending out through a first end of the casing to define a ring passageway through which a key ring is attachable, a hook member contacting the swivel member within the casing and extending out through a second end of the casing, and a spring located within the casing for urging the hook member toward the first end of the casing, thereby maintaining continuous contact between the hook member and the swivel member. By depressing the swivel member, thereby compressing the spring, the hook member is urged out from the casing to provide access to the end of the hook member around which a key ring is attachable.
