Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
208 words
A ramp attachment for a wheel chair which has a frame supporting a seat at a predetermined height above a floor support and having wheel means associated with said frame for moving said chair over said floor support and said frame including two generally parallel rigid frame members running from front to rear respectively at opposite sides of the chassis of said chair; the combination for use therewith of an elongated ramp having a width less than that of said seat and having a length not over a few feet; a ramp support base consisting of rod means of a length to just reach between said two quickly removable rigid frame members when said chair is in operating condition; two connecting means one at each end of said ramp support base respectively adapted to firmly connect said support base on said two rigid frame members; and a ramp support including a vertical rigid strut having means at its lower end for detachable connection to said ramp support base and having means at its upper end for attachment to one end of said ramp; said ramp support being of a length to hold said one end of said ramp approximately at the level of said seat of said chair.
Claim 2
Dependent Claim
208 words
A ramp attachment for a wheel chair which has a frame supporting a seat at a predetermined height above a floor support and having wheel means associated with said frame for moving said chair over said floor support and said frame including two generally parallel rigid frame members running from front to rear respectively at opposite sides of the chassis of said chair; the combination for use therewith of an elongated ramp having a width less than that of said seat and having a length not over a few feet; a ramp support base consisting of rod means of a length to just reach between said two quickly removable rigid frame members when said chair is in operating condition; two connecting means one at each end of said ramp support base respectively adapted to firmly connect said support base on said two rigid frame members; and a ramp support including a vertical rigid strut having means at its lower end for detachable connection to said ramp support base and having means at its upper end for attachment to one end of said ramp; said ramp support being of a length to hold said one end of said ramp approximately at the level of said seat of said chair.
Claim 3
Dependent Claim
67 words
A ramp attachment for a wheel chair as defined in claim 1, wherein said chair is of a type to be folded together at a vertical center line thereof when not in use, wherein said ramp support base rod means comprises two rods of equal length and a hinge connected at their mutually meeting ends permitting said ramp support base to fold as the chair is folded.
Claim 4
Dependent Claim
92 words
A ramp attachment for a wheel chair as defined in claim 1, wherein said connecting means at each end of said ramp support base comprises a flexible tension clip member having means for connection at one of its ends to said ramp support base rod means, then of a length to extend snugly around one of said parallel rigid frame members, and having means for connection at the other of its ends to said ramp support base rod means, at least one of said last named connections being quickly connectible and disconnectible.
Claim 5
Dependent Claim
51 words
A ramp attachment for a wheel chair as defined in claim 1, wherein said means at thE lower end of said vertical rigid strut comprises a U-shape clamp opening downwardly having a web attached to said strut, and having parallel flanges spaced to snugly engage said ramp support base rod means.
Claim 6
Dependent Claim
68 words
A ramp attachment for a wheel chair as defined in claim 1, wherein said means at the upper end of said vertical strut comprises a grooved fitting secured to said ramp, and a fitting fixed in said strut and including a spring controlled catch of a size and so positioned as to engage in said grooved fitting and then to hold said ramp firmly attached to said strut.
Claim 7
Dependent Claim
245 words
A ramp attachment for a wheel chair which has a frame supporting a seat at a predetermined height above a floor support and having wheel means associated with said frame for moving said chair over said floor support and said frame including two generally parallel rigid frame members running from front to rear respectively at opposite ends of the chassis of said chair; the combination for use therewith of an elongated ramp having a width less than that of said seat and having a length not over a few feet; a ramp support base consisting of two rods of equal length and diameter and a hinge connecting their mutually meeting ends, an outwardly opening C-clamp at the outer end of each rod of a size to snugly embrace one of said parallel rigid frame members respectively, said ramp support base and said C-clamps of a length to fit snugly between said parallel rigid frame members in operating position of said chair, a quickly adjustable clip member connected to hold said C-clamps firmly to said rigid frame members; a rigid strut having a downwardly opening U-shape clamp rigidly attached at its lower end, said U-shape clamp of a size to fit firmly over either of said two rods; and a quickly manipulatable connection for said ramp and strut including a fitting fixed on the under side of said ramp near one of its ends and a coacting fitting fixed on the upper end of said strut.
