Abstract: The present invention provides a linear fastening system capable of rapid engagement and disengagement. More specifically, the system utilizes a cooperating collet member and a compression ring member which are constructed and arranged to slip easily over a shank member. The fastener system is secured by linearly traversing a compression member in an overlapping fashion over the collet member thereby utilizing ribbed surfaces to compress the collet member to grip the outer surface of the shank member. In this manner, the linear fastener system is capable of providing a precise, secure, and reproducible connection between multiple components without the need to apply rotational torque to the assembly.

Abstract: A toggle-bolt type fastener has pocket structure incorporated therein for accommodating extra-long threaded bolt fasteners in a coaxial manner within the toggle-bolt type fastener. Alternatively, structure has been incorporated within the toggle-bolt type fastener which accommodates extra-long threaded bolt fasteners by causing the same to be slightly deflected from their coaxial disposition within the toggle-bolt type fastener so as to permit the same to bypass the pointed tip of the toggle-bolt type fastener. Still further, additional structure has been incorporated within the toggle-bolt type fastener for ensuring the fact that when the nut member is moved from its original, axially oriented, inoperative or non-deployed position, to its second, transversely oriented, operative or deployed position, the nut member will in fact be disposed substantially perpendicular to the longitudinal axis of the toggle-bolt type fastener so as to ensure the proper threaded engagement thereby by the threaded bolt fastener.

Abstract: An integrally molded glide cover has a top and a base that interlock together to surround and encapsulate the lower portion of an existing furniture glide. A rim protrudes downwardly from the bottom of the base and surrounds a recessed bottom surface for receiving an insert that is adapted for sliding on floors without damaging the floor surface. A hinge allows the base to close over the bottom of the glide and into direct alignment with locking prongs on the top for interlocked attachment of the base to the top using one hand and no tools. When interlocked, the top and base provide a tamper-proof permanent attachment that presents a low profile appearance closely resembling the exterior configuration of the encapsulated lower glide portion.
