Abstract

1441465 Hand trolleys O JENSEN 29 June 1973 [5 July 1972] 31227/73 Heading B7B A trolley comprises a wheeled chassis 2 having relatively movable wheels 4, 6 interconnected by an extensible member, a load frame 16 pivotally mounted on shaft 8 and stays 42 extending between the frame and the rear wheels so that on rearward inclination of frame 16 the rear wheels 6 are moved away from the front wheels. In one embodiment the wheels are interconnected by telescopic tubes 10, 12 to allow relative movement ; in another embodiment a scissor mechanism is used. The frame is provided with a small fixed and a larger movable toe plate 36, 38 respectively, and is releasably and pivotally connected by telescopic tubes 48, 58 to the chassis. The tubes 48, 50 allow the angle of inclination of the frame to be adjusted by inserting stop pins in transverse bores of tube 50. Tube 48 may be disconnected from the frame and folded down on to the chassis; this allows the frame to be lowered to overlie the chassis whereupon the frame and chassis may be secured together by a bracket 56 and locking pin 58 to form a toe-plate trolley (Fig. 4, not shown). A handle structure 28 has its limbs telescopically received in side frame members 18 so as to be adjustable and removable. With the frame and chassis secured in overalying relationship, the handle structure may be mounted in a vertical position in sockets 54 on members 18 thus forming a push cart.
