Shopping trolley for disabled and elderly - has scissors hinged frames serving as walking support and fcgable into seat

摘要

The shopping trolley has two identical frames (1, 2) hinged scissors fashion, and with one frame fitted with wheels (7). Both frames fold flat to act as a walking support, with handgrips at the top. The frames are inverted U-shapes with the handgrips as additional frames welded to the top. A folded fabric seat (8) is slung between the frames to allow the user to sit on the frames after they are unfolded. A shopping bag (9) is slung from one frame to hold a small amount of shopping. To prevent the folded frames from unfolding the handgrips are clamping together by an elastic sleeve (5).
