Abstract
Abstract A slide assembly having particular use for extension tables. The slide assembly includes a series of slide members disposed in interconnected side-by-side relation, with each slide member adapted to move relative to the adjacent slide member between a retracted and extended position. The side surfaces of the slide members are provided with longitudinal female dovetail grooves and blocks having mating male dovetail portions, are secured to one slide member and fireely slidable within the groove of the adjacent slide member. Each block has thin longitudinal extensions or fins disposed between adjacent opposed longitudinal edges of the slide members to provide smooth and noisless sliding action.
