Stop retainer assembly for full-open drawer slide track

Abstract

A stop assembly for the full-open drawer slide track consists of at least a projected tenon stamped formed at the end of the intermediate slide track and a stop retainer and a stop releaser mounted on the extension slide track in which the stop retainer and the stop releaser are under the compression spring to maintain in the normal operation condition. The stop retainer has a mitered guide to lead the projected tenon skidding into the slot under the stop retainer. While the extension slide track is being pulled outward, the mitered guide of the stop retainer will lead the projected tenon of the intermediate slide track into the slot of the stop retainer and the drawer will completely stop therein without further an outward over slide. This is a safety protection design for the drawer.

1 . A novel stop retainer assembly for the full open drawer slide track mainly comprises a projected tenon stamp-formed on the intermediate slide track and a stop retainer and stop releaser mounted on the extension slide track; 
 the stop retainer has a conical point rod at the rear end linking with a bevel, an elastic retaining plate which forms inward slot and a miter slope to guide the projected tenon into the proper lock position; when the extension slide track is being pulled out, the bevel will lead the projected tenon sliding under the pressure to the slot without jumping and displacement; the projected tenon will be guided by the bevel into the proper position formed by the mitered slope and the slot;    the stop releaser constitutes a releaser, a pressure spring exerting pressure on the releaser, a spring puller at the far end of the extension slide track and a pushing rod; the releaser has a mitered guide contacting with front end of the stop retainer; when the spring puller is being pulled outward, the releaser is being pushed outward working as a lever at the miter guide to free the projected tenon form the slot of the stop retainer, permitting the drawer to be pushed to the closing position.    
   
   
       2 . The stop retainer assembly as claimed in the  claim 1  in which the front point of the stop retainer is mounted on the extension slide track under a pressure exerted by a pressure spring so as to keep the bevel of the conical point rod always closely contacting the side wall of the extension slide track to guide the projected tenon sliding under pressure.
