Abstract
Load conveyor comprising a pneumatic mat comprising first elements and second elements which are inflatable respectively by a first and second inflating circuit, the elements having fixed ends in relation to a face of the mat and free ends capable of being brought, by means of the inflating circuits, by a pivoting movement, from a rest position to a work position, the elements having a same parity always being parallel to one another and situated on a same side in relation to their fixed ends, the projections of the first elements being parallel to the projections of the second elements, but pointing in opposite directions.
Claims8
A load conveyor comprising a mat including first and second juxtaposed inflatable elements, said elements each having an upper supporting surface for a load and a lower surface resting on the mat, a plurality of members longitudinally spaced along each said element and having first ends attached to said mat along the lower surface of said element, said members having second movable ends opposite the first ends operatively associated with the respective element to undergo pivotal movement as the associated element is inflated and deflated, said members of each element being parallel to one another and initially inclined with the vertical when the associated element is deflated and undergoing tilting towards the vertical during inflation of said element to transport a load on said upper surface in the direction of tilting, said members of the two elements being inclined in opposite directions and undergoing opposite directions of tilting when their respective elements are inflated such that one element transports the load in one direction during inflation and the other element transports the load in the same direction during deflation.
