Flexible folding sling
View Patent ↗A flexible folding sling includes a flexible elongate preform strap having first and second ends, each of the first and second ends folded inward toward a strap center to form respective first and second loops. The first and second ends are fastened to the strap center with each of the first and second loops having a half-twist such that each of the first and second loops is a tear-shaped Mobius loop. The flexible folding sling assists a user in carrying bag(s) having handles, or other objects that include handles or like structure. When used to carry bags, the sling can be configured as a hand-sling, a shoulder-sling or a back-sling. When used as a hand-sling, the sling engages the user's wrist in a secure and comfortable manner. This prevents load transmission through the easily tired hand muscles and ligaments, extending the amount of time the user can carry a load. This also allows the user to maintain use of her hand and fingers while the sling is used.

A hand-sling for carrying and transporting at least one bag or similar object, each of said at least one bag having a handle, the hand-sling comprising the flexible folding sling of claim 1 , wherein the strap has a width and a length such that the strap extends through each of the handles of the at least one bag, wherein the first and second loops are releasably secured together by the hook fastener patch and the loop fastener patch.
6. The hand-sling of claim 5 , wherein the hand-sling has a top opening with a top opening axis and a bottom opening with a bottom opening axis, each of the handles of the at least one bag is captured in the bottom opening so that each of the handles is proximate the strap center and wherein the top opening axis and the bottom opening axis are offset from each other by approximately 90 degrees.
7. The hand-sling of claim 6 , wherein the top opening has a concave interior engagement surface formed by an inner surface of a rounded end of the first loop, the concave interior engagement surface adapted to conform to a wrist of a user.
8. The hand-sling of claim 7 , wherein a bottom portion of the bottom opening has a capture channel, the capture channel configured and dimensioned to orient each of the handles of the at least one bag such that multiple bags are maintained in a single-file bag group.
9. The hand-sling of claim 8 , wherein the strap has a substantially uniform width along the entire length of the strap.
10. A shoulder-sling for carrying and transporting at least one bag or similar object, each of said at least one bag having a handle, the shoulder-sling comprising the flexible folding sling of claim 1 , wherein the strap has a width and a length such that the strap extends through each of the handles of the at least one bag, wherein the first loop is passed through the second loop to capture each of the handles of the at least one bag.
11. A back-sling for carrying and transporting at least one bag or similar object, each of said at least one bag having a handle, the back-sling comprising first and second flexible folding slings of claim 1 , wherein the first loop of the first flexible folding sling is passed through the second loop of the second flexible folding sling and the first loop of the first flexible folding sling is passed through the second loop of the first flexible folding sling.
12. A method of carrying and transporting at least one bag or similar object, each of said at least one bag having a handle, the method comprising:
extending the strap of the flexible folding sling of claim 1 through each of the handles of the at least one bag; and
releasably securing the first and second loops together with the hook fastener patch and the loop fastener patch.
13. The method of claim 12 , wherein the flexible folding sling has a top opening with a top opening axis and a bottom opening with a bottom opening axis, each of the handles of the at least one bag is captured in the bottom opening so that each of the handles is proximate the strap center and wherein the top opening axis and the bottom opening axis are offset from each other by approximately 90 degrees.
14. The method of claim 13 , wherein the top opening has a concave interior engagement surface formed by an inner surface of a rounded end of the first loop, the concave interior engagement surface adapted to conform to a wrist of a user.
15. The method of claim 14 , wherein the strap has a substantially uniform width along the entire length of the strap.
16. A flexible folding sling for carrying and transporting at least one bag or similar object, each of the at least one bag having a handle, the flexible folding sling comprising:
a flexible elongate preform strap having first and second ends and a strap center located at a midpoint between the first and second ends, each of the first and second ends folded inward toward the strap center and fixedly attached to the strap center to form respective first and second loops,
wherein each of the first and second loops has a half-twist such that each of the first and second loops is a tear-shaped Mobius loop,
wherein the first and second loops are provided with a securing member for releasably securing the first loop to the second loop,
wherein the securing member includes a hook fastener patch on a side of the first loop and a loop fastener patch on a side of the second loop, with one of the hook fastener patch and the loop fastener patch facing toward the strap center and the other of the hook fastener patch and the loop fastener patch facing away from the strap center, and
wherein the hook fastener patch is centered at an apex of the first loop and the loop fastener patch is centered at an apex of the second loop.
17. The flexible folding sling of claim 16 , wherein the hook fastener patch is substantially the same size as the loop fastener patch.
18. A hand-sling for carrying and transporting at least one bag or similar object, each of said at least one bag having a handle, the hand-sling consisting of a flexible folding sling comprising:
a single continuous one-piece flexible elongate preform strap having first and second ends and a strap center located at a midpoint between the first and second ends, each of the first and second ends folded inward toward the strap center and fixedly attached to the strap center to form respective first and second loops,
wherein each of the first and second loops has a half-twist such that each of the first and second loops is a tear-shaped Mobius loop,
