Abstract
A shopping basket is comprised of an arrangement of plural lazytongs frames movable from folded to extended position in which they constitute an erected structure having a floor provided by support bars, these support bars including long bars and short bars connected to the lower part of the enclosure. By selectively adjusting the effective lengths of the long support bars, the envelope and hence capacity of the erect structure can be changed. The structure can embody wheels and a handle thereon so that the basket serves as a readily movable shopping cart.
Claims19
A structure erectable from a folded condition thereof to an erected condition wherein the structure presents an upright enclosure having a plurality of planar sides, and a floor supported from a lower part of the enclosure, the structure comprising
- a corresponding plurality of lazytongs frames connected each at both of opposite frame sides to another one of said lazytongs frames so that extension of any one lazytongs frame from a retracted to extended position causes extension of the other lazytongs frames, the extended lazytongs frames defining the enclosure, the floor comprising
- a plurality of support bars, the bar plurality including longer support bars and shorter support bars, a first end of each longer support bar being connected to the enclosure lower part at the location where a lazytongs frame side is connected to an adjacent lazytongs frame side, a first end of each shorter support bar being connected to the enclosure lower part at a location intermediate the opposite sides of a lazytongs frame, a second opposite end of each longer support bar and a second opposite end of each shorter support bar being connected to a hub fitting about which all of the support bars radially array with the enclosure in erect condition, the shorter support bars being telescopic members which telescopically adjust in length during folding and erection of the enclosure, the plan expanse of the enclosure in erect condition being set by a predetermined length of the longer support bars.
A structure erectable from a folded condition thereof to an erected condition wherein the structure presents an upright rectangular enclosure and a floor supported from a lower part of the enclosure, the structure comprising
- four lazytongs frames connected each at both of opposite frame sides to another one of said lazytongs frames so that extension of any one lazytongs frame from a retracted to extended position causes extension of the other lazytongs frames, the extended lazytongs frames defining the enclosure, the floor comprising
- a plurality of support bars, the bar plurality including longer support bars and shorter support bars, a first end of each longer support bar being connected to the enclosure lower part at the location where a lazytongs frame side is connected to an adjacent lazytongs frame side, a first end of each shorter support bar being connected to the enclosure lower part at a location intermediate the opposite sides of a lazytongs frame, a second opposite end of each longer support bar and a second opposite end of each shorter support bar being connected to a hub fitting about which all of the support arms radially array with the enclosure in erect condition, and
- means for selectively adjusting the length of each longer support arm to a predetermined one in a range of such lengths whereby a change of longer arm length produces in an erected condition enclosure a changed enclosure plan expanse area and correspondingly changed enclosure volume, the shorter support arms being telescopic members which telescopically adjust in length responsive to change in said enclosure plan expanse area.
