Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
167 words
A device attachable to an elevatable legrest of a wheel chair for retaining the leg of a person sitting in the wheel chair upon the legrest comprising: a body portion; clamping means connected to said body portion for releasably clamping same to an elevatable legrest of a wheel chair during use of the device; and retaining means connected to said body portion for retaining the leg of a person sitting in the wheel chair upon the elevatable legrest by preventing lateral inward movement of the leg; the device being composed of a single sheet of resilient material configured at one end into said clamping means and configured at the other end into said retaining means; and wherein said clamping means comprises an arcuate end portion of said sheet and said retaining means comprises another arcuate end portion of said sheet and wherein said body portion is interposed between and interconnects said arcuate end portions; whereby the device prevents the person''s leg from falling off the elevatable legrest.
Claim 2
Independent Claim
167 words
A device attachable to an elevatable legrest of a wheel chair for retaining the leg of a person sitting in the wheel chair upon the legrest comprising: a body portion; clamping means connected to said body portion for releasably clamping same to an elevatable legrest of a wheel chair during use of the device; and retaining means connected to said body portion for retaining the leg of a person sitting in the wheel chair upon the elevatable legrest by preventing lateral inward movement of the leg; the device being composed of a single sheet of resilient material configured at one end into said clamping means and configured at the other end into said retaining means; and wherein said clamping means comprises an arcuate end portion of said sheet and said retaining means comprises another arcuate end portion of said sheet and wherein said body portion is interposed between and interconnects said arcuate end portions; whereby the device prevents the person''s leg from falling off the elevatable legrest.
Claim 3
Dependent Claim
35 words

Claim 4
Dependent Claim
102 words
In combination: a wheel chair having an elevatable legrest for supporting thereon the leg of a person sitting in said wheel chair; and a device detachably connected to said elevatable legrest and cooperarive therewith to retain the leg of a person sitting in the wheel chair upon said legrest by preventing lateral inward movement of the leg beyond a limited extent along said legrest, said device including retaining means extending outwardly from said legrest to an extent sufficient to block and prevent lateral inward movement of the leg beyond a limited extent along said legrest thereby retaining the leg upon said legrest.
Claim 5
Dependent Claim
102 words
In combination: a wheel chair having an elevatable legrest for supporting thereon the leg of a person sitting in said wheel chair; and a device detachably connected to said elevatable legrest and cooperarive therewith to retain the leg of a person sitting in the wheel chair upon said legrest by preventing lateral inward movement of the leg beyond a limited extent along said legrest, said device including retaining means extending outwardly from said legrest to an extent sufficient to block and prevent lateral inward movement of the leg beyond a limited extent along said legrest thereby retaining the leg upon said legrest.
Claim 6
Dependent Claim
49 words
A combination according to claim 3; wherein said device further comprises a body portion connected to said retaining means and overlying a portion of said legrest such that said device rests upon said legrest, and clamping means connected to said body portion releasably clamping same to said elevatable legrest.
Claim 7
Dependent Claim
94 words
A combination according to claim 3; wherein said elevatable legrest includes an elevatable tubular member, and a legrest panel connected to said tubular member for supporting and resting thereon the leg of the person sitting in said wheel chair; and wherein said device comprises a body portion connected to said retaining means, and clamping means connected to said body portion releasably clamping same to said tubular member in a position wherein said body portion overlies and rests upon at least a portion of said legrest panel such that said device rests upon said legrest.
Claim 8
Dependent Claim
34 words
A combination according to claim 5; wherein said device comprises a single sheet of resilient material configured at one end into said clamping means and configured at the other end into said retaining means.
Claim 9
Dependent Claim
