Claim 4

A support for a bag comprising, side members; hinged connections between the side members; means secured to at least one of the side members for maintaining the side members in a desired angular relationship; and means for securing a bag to the support; wherein the support has four sides; two opposite sides comprise rectangular members including upper and lower horizontal members, and upright members secured to the upper and lower horizontal members; and each of the other two opposite sides comprise spaced upper and lower cross members.

Claim 5

The combination called for in claim 2 wherein the means secured to at least one of the sides for maintaining the sides in a desired angular relationship comprises resilient means extending between the upper and lower cross members.

Claim 6

The combination called for in claim 3 wherein the resilient means extending between the upper and lower cross members include elongated spring members secured to the cross members.

Claim 7

The combination called for in claim 2 wherein the means for securing a bag to the support comprises resilient retainer means constructed and arranged to engage a portion of a bag.

Claim 8

The combination called for in claim 2 wherein the hinged connections comprise loops formed in opposite ends of the cross members constructed and arranged to encircle a portion of the upright members.

Claim 9

The combination called for in claim 2 wherein the means for maintaining the side members in a desired angular relationship includes vertically disposed spring rods extending between the upper and lower cross members.

Claim 10

The combination called for in claim 2 wherein the upper and lower horizontal members, the upright members, and the upper and lower cross members are elongated rods.

Claim 11

A support for a bag comprising, four substantially rectangular side members; hinged connections between the side members forming corners, said hinged connections being arranged to connect the side members to form a deformable parallelogram-shaped top and bottom such that inwardly directed diagonally opposed forces applied to opposite corners of the support will deform the support to a substantially flat configuration; and a resilient member extending between sides of at least one of the substantially rectangular members to urge adjacent side members into pressure relation to frictionally maintain the side members in a desired angular relationship.

Claim 12

A support for a bag comprising, four substantially rectangular side members; hinged connections between the side members forming corners, said hinged connections being arranged to connect the side members to form a deformable parallelogram-shaped top and bottom such that inwardly directed diagonally opposed forces applied to opposite corners of the support will deform the support to a substantially flat configuration; and a resilient member extending between sides of at least one of the substantially rectangular members to urge adjacent side members into pressure relation to frictionally maintain the side members in a desired angular relationship.

Claim 13

A support for a bag comprising, a base having elongated rigid side members; means to hingedly connect the side members together; upwardly extending members having lower ends secured to said base; resilient adjusting means operably connected to the side members of the base to urge the contacting surfaces on at least two of said side members into pressure relation to frictionally maintain the sides of the base in a desired angular relationship; and means for securing a bag to the upwardly extending members.

Claim 14

A support for a bag comprising, a base having elongated rigid side members; means to hingedly connect the side members together; upwardly extending members having lower ends secured to said base; resilient adjusting means operably connected to the side members of the base to urge the contacting surfaces on at least two of said side members into pressure relation to frictionally maintain the sides of the base in a desired angular relationship; and means for securing a bag to the upwardly extending members.

Claim 15

A support for a bag comprising, spaced upper members; spaced cross braces; hinge means to connect opposite ends of the cross braces to ends of the spaced upper members; downwardly extending support members secured to the upper members; and deformable rods having ends secured to said cross braces and the support members to apply pressure through the hinge means to frictionally maintain a desired variable angular relationship between the upper members and the cross braces.

Claim 16

A support for a bag comprising, spaced upper members; spaced cross braces; hinge means to connect opposite ends of the cross braces to ends of the spaced upper members; downwardly extending support members secured to the upper members; and deformable rods having ends secured to said cross braces and the support members to apply pressure through the hinge means to frictionally maintain a desired variable angular relationship between the upper members and the cross braces.

Claim 17

A support for a bag comprising, peripheral means having a central opening formed therein; leg elements for suppOrting the peripheral means; hinge members joining the peripheral means and the leg elements; and spring tension means extending between adjacent leg elements to apply force through said leg elements to the hinge members to maintain the leg elements in a desired angular relation to the peripheral means, said spring tension means being adapted to apply pressure to the hinge members without exerting force tending to rotate the leg elements relative to the peripheral means.

Claim 18

A support for a bag comprising, peripheral means having a central opening formed therein; leg elements for suppOrting the peripheral means; hinge members joining the peripheral means and the leg elements; and spring tension means extending between adjacent leg elements to apply force through said leg elements to the hinge members to maintain the leg elements in a desired angular relation to the peripheral means, said spring tension means being adapted to apply pressure to the hinge members without exerting force tending to rotate the leg elements relative to the peripheral means.
