ADJUSTABLE LEGS FOR DESK AND THE LIKE |
摘要 |
A school desk has legs adapted to be lengthened for raising the desk. The legs are provided with a sleeve adapted to fittingly slide on the legs. The legs have a transversal perforation, and the sleeves have a set of vertically disposed holes. A screw and nut combination is used to lock the sleeves on the legs at selected vertical positions. The sleeves are vertically grooved to facilitate their sliding action and to allow the screw and nut combination to positively lock the sleeves on the legs.
