发明名称 Extensible table
摘要 An extensible table has a rectangular frame with pairs of longitudinal beams and cross beams, a leg at each corner, and two draw-out plates which can be selectively stacked, and aligned in co-planar condition. The improvement is that each leg has a top recess in which is engaged a male portion of a shoulder element including an upper L-shaped portion defining a cavity to receive the cross beams. Roller means are on one arm of the L-shaped portion to carry the draw-out plates. Each longitudinal beam has on an inner face a mirror-image groove formation in which are received lateral rollers on the draw-out plates.
