A SYSTEM OF FASTENERS FOR ATTACHING PANELS ONTO MODULES THAT ARE TO BE INSTALLED ON AN AIRPLANE GROUND SUPPORT EQUIPMENT CART

摘要

A captive fastener system for use in removably attaching cover panels to openings in the sides of modules containing equipment on airplane ground support equipment carts. Sets of fasteners each include: a nut (98) having mounted on its surface a hollow, internally- threaded shaft (99) smaller in diameter than the nut, the shaft fitting into the shelf 's fastener holes; a bolt (92) having a head shaped to engage a fastener driving tool and having a shaft unthreaded (93) adjacent the head and threaded (95) away from the head, the threads matching the nut shaft's internal threads; and a panel hole liner (94) and bolt support formed as a cylinder sized to be force fitted into the panel's fastener holes, the cylinder having a bottom with a central hole slightly larger in diameter than the unthreaded portion of the bolt shaft such that the bolt is retained within the hole liner free to rotate and to slide up and down but not free to fall out.
