The table has a frame, a leaf and a cupboard mounted below the table leaf which is adjustable on guides along its length. The cupboard (3) is freely movable over the whole length of the table (1,2) through rolling elements (6,7) which work together with the guides (4,5). The rolling elements are small wheels (6,7) movable on rails which are attached to the frame (1). The upper wheel (6) has an 'L' shaped rim with a radial flange which is supported on the lower flange of the 'U' profiled upper rail. The rail for the lower wheel has a 'Z' profile positioned in the angle between the body of the table (10) and the lower leg (9) of the frame. |
