Convertible Transport Trolley Having a Pair of Fold-Away Legs and Simultaneously Fold-Away Wheels

摘要

A transport trolley (CT) comprises: a pair of legs (J1) each having a lower end to which there is coupled a plate (PT1) on which at least one wheel (R1) is mounted so as to rotate in a transverse direction, first load supporting means (S1) coupled to the lower ends of the legs (J1), first coupling means (MC1) on which the lower ends of the legs (J1) are mounted so as to rotate in the transverse direction such that they can move from a folded-out position to a folded-away position, and on which the plates (PT1) are mounted so as to rotate such that wheels (R1) thereof can pivot and move from a folded-out position to a folded-away position approximately parallel to the folded-away legs (J1), and second coupling means (MC2) designed to force the legs (J1) and the wheels (R1) to be substantially simultaneously either in their folded-away position or in their folded-out position.

1. A transport trolley comprising a pair of legs each comprising a lower extremity to which is coupled a plate on which is rotatably mounted in a transverse direction at least one wheel, and first load support means coupled to said lower extremities of the legs, wherein the transport trolley further comprises i) first coupling means on which are rotatably mounted said lower extremities of legs in said a transverse direction so that they can change from a straightened-out position to a folded-away position, and said plates so that their wheels can pivot under load and change from a straightened-out position to a folded-away position approximately parallel to said folded-away legs, and ii) second coupling means arranged to force said legs and said wheels to be approximately simultaneously in either their folded-away position, or in their straightened-out position, and in that said wheels are suitable to pivot under load according to a longitudinal axis of rotation positioned near the floor.
