Abstract

A carrying bag comprises at least one extensible panel forming at least a part of the external walls of the bag. The extensible panel is of a composite material composed of a sheet of a stretch-knit fabric and a multiplicity of elongated strips of a durable, substantially non-extensible material joined to the fabric sheet in closely spaced relation by stitching located proximate to the centers of the strips, thereby leaving portions of the fabric sheet underlying the major portions of the strips free to stretch.

Claims

1. A carrying bag having external walls defining a receptacle for objects comprising at least one extensible panel forming at least a part of the external walls of the bag, the extensible panel being of a composite material composed of a sheet of a stretch-knit fabric and a multiplicity of elongated strips of a durable, substantially non-extensible material joined to the fabric sheet in closely spaced relation by stitching spaced apart from the edges of the strips, thereby leaving portions of the fabric sheet underlying the major portions of the strips free to stretch.

2. A carrying bag according to claim 1 wherein the extensible panel has opposite ends oriented transversely to the strips and opposite sides oriented transversely to the ends and wherein the ends of the extensible panel are joined to members forming portions of the bag that are substantially non-extensible so that stretching of the ends of the extensible panel in a direction transverse to the strips is substantially prevented.

3. A carrying bag according to claim 2 wherein the extensible panel is joined along its ends and sides to members that are substantially non-extensible and are inhibited from displacing relative to each other such that they restrict stretching of the extensible panel.

4. A carrying bag according to claim 3 having opposite side walls, opposite end walls, a top wall and a bottom wall, each of which walls is substantially rectangular, and wherein the extensible panel forms substantially all of at least one of the top and bottom walls.

5. A carrying bag according to claim 4 wherein the side and end walls of the bag are substantially rigid such that they restrict stretching of the extensible panel by inhibiting relative displacements of its ends and sides.

6. A carrying bag according to claim 4 wherein the side and end walls of the bag are substantially non-extensible and flexible such that they can displace relative to each other to permit the extensible panel to stretch by enabling relative displacements of its ends and sides but also inhibit stretching of the extensible panel by substantially preventing stretching along the edges and sides of the extensible panel.

7. A carrying bag according to claim 1 having a top wall and a bottom wall bounded by smoothly curved margins and a peripheral wall joined to the top and bottom walls, the peripheral wall being the extensible panel of the bag.

8. A carrying bag according to claim 7 wherein the extensible panel has opposite ends oriented transversely to the strips and opposite sides oriented transversely to the ends and wherein the ends of the peripheral wall are joined to the top and bottom walls of the bag and the strips extend transversely to the top and bottom walls.

9. A carrying bag according to claim 8 wherein the bottom wall is substantially rigid and further comprising a carrying strap attached to the bottom wall of the bag.

10. A carrying bag according to claim 9 wherein the carrying strap is integral with oppositely located strips of the extensible panel.

11. A carrying bag according to claim 1 having a substantially rigid bottom wall bounded by a smoothly curved margin and a peripheral wall joined to the bottom wall, the peripheral wall being the extensible panel of the bag.

12. A carrying bag according to claim 11 wherein the extensible panel has opposite ends oriented transversely to the strips and opposite sides oriented transversely to the ends and wherein one side of the peripheral wall is joined to the bottom wall of the bag and the strips extend peripherally.

13. A carrying bag according to claim 12 and further comprising a carrying strap affixed to the bottom wall.

14. A carrying bag according to claim 13 wherein a strip of the extensible panel adjacent the top of the bag has a multiplicity of holes and further comprising a drawstring passing through the holes and forming a drawstring closure for the bag.

15. A composite material composed of a sheet of a stretch-knit fabric and a multiplicity of elongated strips of a durable, substantially non-extensible material joined to the fabric sheet in closely spaced relation by stitching spaced apart from the edges of the strips, thereby leaving portions of the fabric sheet underlying the major portions of the strips free to stretch.

16. A composite material according to claim 15 wherein the elongated strips are natural leather.

17. A composite material according to claim 15 wherein the elongated strips are synthetic leather.
