The foot release (10) element (11) fitted to the top surface of the flexible plate (4) reaches in part through a hole (12) in the standing base (2), the hole dimensioned to prevent the element jamming or sticking fast. The flexible element material (11) produces a hollow interior connected to a channel (19) in the base plate (4) to vent air from the element (11) when this is compressed. The element can be integrated with the plate whose centre ring strip (15) plugs into an opening (13) in the base of the foot (2) and in so doing joins plate and base with the aid of a locking element. The locking element comes in the form of a stopper (16) which splays the ring out (15) when plugged into this (15). The plate can also be bonded to the base standing surface, using an adhesion area equal to the base area of the bin etc (10) supported by the foot. Bin and foot can be positively locked and freed by their mutual twisting movement, aided by a grip fitted to base in the form of a flange etc (14) fitted to the top of the standing base (2). Two flanges on different sides adjoining the release element (10) guard against possible inadvertent release action. |
