Folding device applicable to waitresses, tea carts or similar

摘要

Folding device applicable to housekeeping carts tea or the like, characterized in that it is constituted by respective cylindrical parts internally hollow, which superiorly and inferiorly by the back metallic angle sections in which upper articulated and above are fixed by suitable elements, the constituent tubular rods of the metal structure of the waitress or cart, whose structure comprises two pairs inferiorly self-steerable wheels for easy movement; resting on the horizontal wings of the upper corner sections, two separate boards provided with handles on which exerts a tensile or compression, for their extension and folding coupled to the aforesaid cylindrical parts, bushings will have plastic provided with side flaps inferiorly arranged, in which the bent ends of respective rods, which at their free ends are inserted inferiorly into the tubular rods of the metal structure to which the lower angular profiles, hinged to the first cylindrical parts are joined and on two introduced which rests a core board provided superiorly bent rods to prevent them from falling objects deposited. With all of which, by exerting tensile stress on the upper handles, the rise of plastic caps on cylindrical parts and thus it causes the opening or deployment of articulated these parts, angular profiles being sufficient to exert a slight effort opposite direction on those same handles, so that articulated these parts, angular profiles being sufficient to exert a slight effort in the opposite direction on those same handles, so that the angle sections return to their initial position and causing the closure or folding cart or waitress .
