Abstract
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.
Claims3
In an extensible table, of that kind which includes a rectangular frame constituted by two opposed spaced parallel longitudinal beams and two opposed spaced parallel cross beams, four legs arranged one at each corner of the frame, and two draw-out plates slidable into a first stacked position and a second position in which they are extended end-to-end, the improvement which comprises:
- i. each said leg having a recess opening at its top end
- ii. four shoulder elements each having a male portion engaged into the recess of a respective leg, and an upper L-shaped portion including two spaced vertical arms defining between them a cavity receiving an end of a longitudinal beam, and a recess receiving an end of a cross beam,
- iii. roller means protruding from the upper end of a vertical arm of the L-shaped portion to carry the draw-out plates,
- iv. the longitudinal beams each having on an inner face opposed to an inner face of the other longitudinal beam a respective mirror-image groove formation,
- v. lateral roller means mounted on said draw-out plates and engaged in said groove formations.
