A slot 37 is cut in the element 35 and a pin 38 fastened in the board 34 rides in the slot, thus limiting the motion of the table and preventing it from being taken out. A handle 39 is provided at the end of the board 34. This handle is fastened to the underside of the board 34 by a plate 40. Theelement 35 is cut out at the end, so as to allow room for the plate 40 and therefore allow the table to be fully closed to the edge of the handle.
