The table framework comprise of two pairs of legs (1,2) which are held together crossways by a lock and adjuster (3). They are freely movable in their longitudinal direction independently of each other, and can be locked in any position. The lock and adjuster comprises two guide articulations (10,11) with a through long hole for each of the legs. These articulations are freely rotatable relatively to each other, and can be locked in any required position at the same time as the legs remain locked in an adjusted position with the aid of a crossways bolt (12). |
