Abstract
Abstract A substantially rectangular sheet of flexible material has longitudinally aligned loops formed along opposite edges for receiving a pair of rigid, elongated handles. The adjacent loops are spaced far enough apart to permit a hand to be inserted between the adjacent loops for the purpose of grasping the exposed portion of the handles to support a person seated on the sheet of flexible material as it hangs downwardly from the handles to function as a sling. A belt is fastened to the upper surface of the sheet by suitably positioned loops and passes around the seated person''s waist to prevent the person from sliding off the sling. The edges of the sling are preferably reinforced with folded fabric tape strips to strengthen the edges and prevent fraying. An opening may be provided in the center of the sling to permit the occupant of the sling to be placed on a toilet seat without the need for subsequently removing and then replacing the sling.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
240 words
An invalid carrying sling for carrying an incapacitated person in a seated position, said sling comprising a flat, generally rectangular sheet of flexible material, a first plurality of loops longitudinally aligned along one side edge of said sheet, a second plurality of loops longitudinally aligned along the opposing side edge of said sheet, a first rigid elongated handle extending through said first plurality of loops, a second rigid elongated handle extending through said second plurality of loops, the individual loops of said first and second plurality of loops being spaced apart from the nearest adjacent loop by a distance which is sufficient to admit a hand between the adjacent loops for the purpose of grasping the exposed portion of the handle to support the sling, a third plurality of loops attached to said sheet and positioned to slidably receive a flexible belt for attaching said incapacitated person to said sling, and a belt extending through said third plurality of loops, a rear panel made of flexible material and attached at one end to said sheet near the rear edge thereof, one of the loops of the third plurality of loops being formed at the other end of said rear panel whereby the rear panel will be supported by said flexible belt to serve as a back for the sling, said rear panel being foldable flat against said sheet to facilitate rolling the sling about one or both of said handles.
Claim 2
Dependent Claim
240 words
An invalid carrying sling for carrying an incapacitated person in a seated position, said sling comprising a flat, generally rectangular sheet of flexible material, a first plurality of loops longitudinally aligned along one side edge of said sheet, a second plurality of loops longitudinally aligned along the opposing side edge of said sheet, a first rigid elongated handle extending through said first plurality of loops, a second rigid elongated handle extending through said second plurality of loops, the individual loops of said first and second plurality of loops being spaced apart from the nearest adjacent loop by a distance which is sufficient to admit a hand between the adjacent loops for the purpose of grasping the exposed portion of the handle to support the sling, a third plurality of loops attached to said sheet and positioned to slidably receive a flexible belt for attaching said incapacitated person to said sling, and a belt extending through said third plurality of loops, a rear panel made of flexible material and attached at one end to said sheet near the rear edge thereof, one of the loops of the third plurality of loops being formed at the other end of said rear panel whereby the rear panel will be supported by said flexible belt to serve as a back for the sling, said rear panel being foldable flat against said sheet to facilitate rolling the sling about one or both of said handles.
Claim 3
Dependent Claim
47 words
The combination defined in claim 1 and further comprising gaps between the exposed portions of said handles and the adjacent edge of said sheet, said gaps each being large enough to admit the fingers of a hand between the handle and the adjacent edge of said sheet.
Claim 4
Dependent Claim
37 words
The combination defined in claim 1 wherein said first and second plurality of loops each comprises three spaced loops providing two exposed portions of said handle whereby each handle may be grasped and supported by two hands.
Claim 5
Dependent Claim

The combination defined in claim 1 and further comprising an opening formed in the central portion of said sheet.
Claim 6
Dependent Claim
35 words
The combination defined in claim 1 and further comprising resilient caps on both ends of said handles, said resilient caps being larger than said loops to prevent the handles from sliding out of the loops.
Claim 7
Dependent Claim
30 words
The combination of claim 5 in which at least one cap on each handle has an air vent in its end to prevent air lock when the cap is removed.
Claim 8
Dependent Claim
