Shopping or warehouse trolley with vertical posts - has platforms hinged at rear, resting on stops at front and having hinged grid flaps at front

摘要

The trolley comprises a frame formed by corner posts (3-5) with platforms (1,7,8) between them, of which the lowest (1) is secured to the posts and carries wheels (2). The other platforms (7,8) have their rear edges hinged (9,10) to the rear posts (4,6) whilst their forward edges rest on stops (23,24) on the forward posts (3,5). These forward edges each have a hinged (19,20;21,22) grid (11,12). These grids may consist of a number of spaced parallel bars whose ends are connected by cross-bars. The hinges may consist of two eyes (19,20;21,22) on each platform for pivot pins fixed to two longitudinal grid bars.
