Abstract

One manifestation of the increasing global competi- tion in the pager industry is the constant pressure to reduce product sales prices. In order to survive in this type of market, manufactures must reduce their manu- factoring costs as much as possible. Perhaps the most efficient way to reduce the cost of any product is to eliminate unnecessary parts by combining their func- tions into a single part.

COMBINATION BELT CLIP LEAF SPRING AND HOUSING LATCH

by Henry Wandt and Dwight Brooks

   One manifestation of the increasing global competi- tion in the pager industry is the constant pressure to reduce product sales prices. In order to survive in this type of market, manufactures must reduce their manu- factoring costs as much as possible. Perhaps the most efficient way to reduce the cost of any product is to eliminate unnecessary parts by combining their func- tions into a single part.

  In current pager designs, belt clip springs are uti- lized solely for the purpose of preloadiig the belt clip. In these designs one or more additional parts are used to secure the front and back housing. A design which eliminates these fasteners benefits from a higher assem- bly efficiency and a lower direct material cost.

  The invention described herein provides a method to combine the single function of a belt clip spring with the function traditionally preformed by separate mechan- ical fasteners. In order to eliminate the mechanical fas-

teners, the belt clip spring is designed to secure the back cover to the front housing at the top of the pager while a mortise and tenon arraignment secures the lower part of the pager.

  To assemble the back cover to the front housing, the back cover is mated to the housing at the lower end (Figure 1). The back cover is then rotated into engage- ment with the front housing. The belt clip sp...
