Abstract

Many communication devices, including pagers, incorporate the use of a single screw or some type of positive fastener to retain a housing. The single screw or fastener is usually located in a side wall or wrner wall of the housing due to the nature of the interlock system. The screw or fastener head is almost always exposed to the outside world to promote easy removal, repair and reassembly Some of the screws are tamperprcof and some are not. Most are recessed to some degree. Most are formed of various metals or sometimes the fasteners are configured of plastics. However, generally speaking, the fasteners are usually single function and purpose, and that is to hold the device's housing together.

LANYARD PIN EYELET USED AS TAMPERPROOF POSITIVE PAGER FASTENING DEVICE

by Jeff King and Mike Goldenberg

   Many communication devices, including pagers, incorporate the use of a single screw or some type of positive fastener to retain a housing. The single screw or fastener is usually located in a side wall or wrner wall of the housing due to the nature of the interlock system. The screw or fastener head is almost always exposed to the outside world to promote easy removal, repair and reassembly Some of the screws are tamperprcof and some are not. Most are recessed to some degree. Most are formed of various metals or sometimes the fasteners are configured of plastics. However, generally speaking, the fasteners are usually single function and purpose, and that is to hold the device's housing together.

   A unique method to save piece parts, assembly costs, and to integrate the system, is to make this fastening device a multifunctional wmponent. This can be accomplished by incorporating the lanyard pin eyelet as an integral part of the structural fastener. The two halves of the typical clam shell or slide together housing are still secured by the preferred fastening method with the exterior portion of the fastenertaking the configuration of the eyelet. The eyelet can be designed in such a way as to allow 360 degree spinning so as not to accidentally or intentionally unfasten the fastener, thus releas- ing the interlo...
