Abstract
Abstract A collapsible basket for carrying side-by-side grocery bags or the like has a rectangular shaped, vertically-extending framework between the lower ends of which are pivotally secured inner end portions of a pair of opposed rectangular bottom panels the outer ends of which have pivotally secured thereto lower end portions of opposed side panels. The upper end corners of the side panels are linked to each other and to central portions along the length of the handle member at each side to provide substantially parallel guide mechanism operation of the side panels with respect to the axial plane of the handle, thereby to permit compact collapsing of the bottom and side panels against each side of the handle member. The lower end of the frame member is provided, centrally along its length, with an inwardly-collapsible handle for use in carrying the container in inverted position when collapsed.

Claim 1
Independent Claim
378 words
A collapsible basket comprising, in combination, a rectangular, vertically-extending frame member, said frame member having a side-to-side, substantially flat bottom wall portion, the ends of said bottom wall portion merging with vertically-upwardly-extending, parallel, substantially flat, side wall portions, the upper ends of said side wall portions being transversely interjoined by a transversely-extending basket handle portion, a pair of rectangular bottom panel members, means pivotally journaling marginal inner edge portions of said bottom panel members with respect to opposed lower end portions of said frame member side wall portions, a pair of rectangular side panel members, means pivotally securing said side panel members along the lower edge each with respect to outer marginal edge portions of said bottom panel members, and parallel guide mechanism interconnecting said side wall portions of said frame member with opposed upper edge portions, respectively, of said side panel members to permit the upward folding of said bottom panel members and said side panel members against opposite sides of said frame member, said parallel guide mechanism comprising elongated link members pivotally interconnecting said side wall portions of said frame member with said upper edge portions of said side panel members, said means pivotally securing said side panel members with respect to said bottom panel members comprising abutment mechanism preventing pivotal movement beyond right-angular disposition therebetween when said side panel members are moved downwardly and outwardly with respect to said frame member into their extended positions of use, and handle means extensible outwardly of the other side of said bottom wall portion of said frame member for carrying said basket when in collapsed and inverted condition, said side panel members and said bottom members all being of identical construction, said abutment mechanism comprising outwardly-projecting portions integrally formed with said side and bottom panel members and having abutting edge portions defined by pivotal radii subtending an angle of 45 degrees with reference to the planes of their respective panels, marginal inner edge portions of said bottom panel members being operative to rest against upper surface portions of said flat bottom wall portion of said frame member when said basket is in its extended position of use, said frame member, said bottom panel members and said side panel members each being integrally formed of a synthetic plastic material.
Claim 2
Dependent Claim
378 words
A collapsible basket comprising, in combination, a rectangular, vertically-extending frame member, said frame member having a side-to-side, substantially flat bottom wall portion, the ends of said bottom wall portion merging with vertically-upwardly-extending, parallel, substantially flat, side wall portions, the upper ends of said side wall portions being transversely interjoined by a transversely-extending basket handle portion, a pair of rectangular bottom panel members, means pivotally journaling marginal inner edge portions of said bottom panel members with respect to opposed lower end portions of said frame member side wall portions, a pair of rectangular side panel members, means pivotally securing said side panel members along the lower edge each with respect to outer marginal edge portions of said bottom panel members, and parallel guide mechanism interconnecting said side wall portions of said frame member with opposed upper edge portions, respectively, of said side panel members to permit the upward folding of said bottom panel members and said side panel members against opposite sides of said frame member, said parallel guide mechanism comprising elongated link members pivotally interconnecting said side wall portions of said frame member with said upper edge portions of said side panel members, said means pivotally securing said side panel members with respect to said bottom panel members comprising abutment mechanism preventing pivotal movement beyond right-angular disposition therebetween when said side panel members are moved downwardly and outwardly with respect to said frame member into their extended positions of use, and handle means extensible outwardly of the other side of said bottom wall portion of said frame member for carrying said basket when in collapsed and inverted condition, said side panel members and said bottom members all being of identical construction, said abutment mechanism comprising outwardly-projecting portions integrally formed with said side and bottom panel members and having abutting edge portions defined by pivotal radii subtending an angle of 45 degrees with reference to the planes of their respective panels, marginal inner edge portions of said bottom panel members being operative to rest against upper surface portions of said flat bottom wall portion of said frame member when said basket is in its extended position of use, said frame member, said bottom panel members and said side panel members each being integrally formed of a synthetic plastic material.
