Abstract

A folding two-wheeled shopping cart having a rigid rear panel, a pair of hinged side panels, a flexible fabric front panel, and a bottom panel hingedly interconnected at a rear edge thereof to the rear panel. The bottom panel is provided with a manually engageable operating member enabling it to be moved between erected and folded positions, the bottom panel also slidably engaging the side panels and maintaining them in erected condition, while simultaneously tensing the front panel, thereby providing a rectangular enclosure for the reception of articles. A flexible canopy is secured at a rear edge thereof to the rear panel, and is selectively engaged with the upper edges of the side panels to cover the above enclosure and protect the contents against the elements when the device is used outdoors. The device can also be used as an open faced hand cart by disconnecting and pivoting the front panel about one or both side panels. In this condition, the device may be used to transport, for example, pieces of luggage, some or all of which may be of overall dimension greater than the enclosure. In this condition, it may also be used as an emergency baby stroller, by providing a pillow and seat. In completely folded condition, the side and bottom panels are placed in substantially coplanar relation with the back panel, and supporting wheels are placed in planes parallel thereto.
