Abstract

Abstract A bag stand is disclosed for supporting the upper edge of a plastic, cloth or paper bag at a convenient height to facilitate filling the bag with raked leaves, grass clippings, or the like. The stand includes a base ring with a generally circular shape with a V-shaped circumferential groove in its periphery. The bag has its upper edge passing up through the open center of the base ring, laying over the top of the base ring and draping down over the periphery thereof. An elastic ring of V-shaped cross section is adapted to fit over the periphery of the base ring, compressing the draped portion of the bag into the circumferential groove of the base ring, frictionally retaining it. A plurality of support flanges are integrally formed with the base ring and depend downwardly and outwardly from it at an angle of approximately five degrees with respect to the vertical. Each flange has a vertical slot in it which opens into an upper horizontal slot. A plurality of support legs are provided, one for each flange, each having a stud projecting from it which slideably engages in the respective vertical slot and locks into the upper horizontal slot of the respective support flange. The outward inclination of each flange imparts a corresponding outward inclination to the respective support leg mounted to it, thereby improving the stability of the bag stand. The legs are easily mounted or removed from the base ring providing for a quick set-up of the bag stand to assist in yard work, followed by a convenient compact storage in its disassembled form.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 258 words
A bag stand, comprising: a horizontal base ring having a generally circular annular shape, with a V-shaped circumferential groove in the periphery thereof, said base ring having a central opening up through which passes the upper edge of a bag which lays over the top of said base ring and drapes down over the periphery thereof, covering said circumferential groove; an elastic ring of V-shaped cross section composed of an elastomeric material, adapted to fit over said downwardly draped portion of said bag, compressing the bag into said circumferential groove of said base ring, for the frictional retention thereof; a plurality of support flanges integrally formed with said base ring and molded as a single unit with said base ring from a plastic material, and depending downwardly and outwardly therefrom at an angle of approximately five degrees with respect to the vertical, each said flange having a vertical slot therein which opens into an upper horizontal slot; a plurality of support legs, one for each of said plurality of flanges, each having a stud projecting from the side thereof, which slideably engages said respective vertical slot and locks into said upper horizontal slot of the respective support flange, each said stud having a head portion for retaining said stud within the respective slots in the respective flange, said plurality of support legs depending downwardly and outwardly from said base ring at an angle of approximately five degrees with respect to the vertical, supporting said upper edge of said bag at a convenient elevated position on said base ring.
Claim 2
Dependent Claim 258 words
A bag stand, comprising: a horizontal base ring having a generally circular annular shape, with a V-shaped circumferential groove in the periphery thereof, said base ring having a central opening up through which passes the upper edge of a bag which lays over the top of said base ring and drapes down over the periphery thereof, covering said circumferential groove; an elastic ring of V-shaped cross section composed of an elastomeric material, adapted to fit over said downwardly draped portion of said bag, compressing the bag into said circumferential groove of said base ring, for the frictional retention thereof; a plurality of support flanges integrally formed with said base ring and molded as a single unit with said base ring from a plastic material, and depending downwardly and outwardly therefrom at an angle of approximately five degrees with respect to the vertical, each said flange having a vertical slot therein which opens into an upper horizontal slot; a plurality of support legs, one for each of said plurality of flanges, each having a stud projecting from the side thereof, which slideably engages said respective vertical slot and locks into said upper horizontal slot of the respective support flange, each said stud having a head portion for retaining said stud within the respective slots in the respective flange, said plurality of support legs depending downwardly and outwardly from said base ring at an angle of approximately five degrees with respect to the vertical, supporting said upper edge of said bag at a convenient elevated position on said base ring.
