  • Fastener
    Patent number: 7491025
    Abstract: A fastener for releasably securing a first substrate to an apertured second substrate includes a base member and a locking member mounted for rotation relative to the base member. The locking member is rotatable between an insertion position for insertion of the base member and locking member through the aperture formed in the second substrate and a locking position for releasably securing the first and second substrates together. A resilient member is provided to bias the locking member toward the base member when the resilient member is compressed. The locking member includes at least one protrusion and the base member includes at least one detent. The detent and protrusion are configured to releasably engage each other in the insertion position of the locking member and disengage from each other upon rotation of the locking member toward the locking position.
