Abstract: A support for a slab or tray intended to be secured to an upright, such as a metallic leg of a table including at least two trays. The support has the general shape of a triangle of which the top of the corner adjacent to the leg has a suitable profile adapted to mate closely with part of the half-periphery of the leg, while each of the sides adjacent to the profile bears a substantially right-angled flange. The fixing of the support to the leg is effected either by welding or by screwing through a small plate fixed to said support. The invention is particularly apt for the construction of tea trolleys, occasional tables and television stands.
