The assembly consists of coupling elements (15,16) on the front end of a wheelchair (1) and the rear end of a shopping trolley which engage when the trolley rear wheels (12) are off the ground. The wheelchair and trolley can be equipped with a lifting mechanism in the form of a bar and cam which slide relative to one another to assist the lifting of the trolley rear end for engagement with the wheelchair, and have spring-loaded catches to hold them in the engaged position. In a variant of the design the cam mechanism can be located on footrests on the wheelchair. |
