Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
182 words
A combination comprising: an elongated support having a plurality of regularly spaced openings along the support; a wheel chair having a pair of laterally spaced rotatable wheels disposed adjacent the support, each wheel having a rim defining an opening and being rotatable about an axis of rotation; first wheel-engaging means mounted on the support and being engaged with a first of said pair of wheels to prevent motion of said first wheel with respect to the support; second wheel-engaging means mounted on the support and being movable toward the second of said pair of wheels along a path of motion parallel to the axis of rotation of the second wheel; an arm carried by the second wheel-engaging means to be received between the opening defined by the rim of the second wheel to prevent motion thereof with respect to the support; and pin means carried by the second wheel-engaging means, said pin means being receivable in a selected opening in the support whereby the first and the second wheel-engaging cooperate to prevent motion of the wheel chair with respect to the support.
Claim 2
Dependent Claim
182 words
A combination comprising: an elongated support having a plurality of regularly spaced openings along the support; a wheel chair having a pair of laterally spaced rotatable wheels disposed adjacent the support, each wheel having a rim defining an opening and being rotatable about an axis of rotation; first wheel-engaging means mounted on the support and being engaged with a first of said pair of wheels to prevent motion of said first wheel with respect to the support; second wheel-engaging means mounted on the support and being movable toward the second of said pair of wheels along a path of motion parallel to the axis of rotation of the second wheel; an arm carried by the second wheel-engaging means to be received between the opening defined by the rim of the second wheel to prevent motion thereof with respect to the support; and pin means carried by the second wheel-engaging means, said pin means being receivable in a selected opening in the support whereby the first and the second wheel-engaging cooperate to prevent motion of the wheel chair with respect to the support.
Claim 3
Dependent Claim
38 words
A combination as defined in claim 1, in which the wheel chair wheels are rotatable about an axis of rotation, and the second wheel-engaging means is movable along a path of motion parallel to said axis of rotation.
Claim 4
Dependent Claim
19 words
A combination as defined in claim 1, including a wheeled vehicle, the support being attached to said wheeled vehicle.
Claim 5
Dependent Claim
29 words
A combination as defined in claim 3, in which the support comprises an elongated tube, the openings being formed in said tube so as to be longitudinally spaced therealong.
Claim 6
Dependent Claim
47 words
A combination as defined in claim 1, in which the first wheel-engaging means is movable along said support to an adjusted position, and including pin means carried by the first wheel-engaging means so as to be receivable in a selected one of said plurality of support openings.
Claim 7
Dependent Claim
32 words
A combination as defined in claim 1, including a bias member carried on the second wheel-engaging means, the bias member being engaged with the pin means to bias it toward the support.
Claim 8
Dependent Claim
269 words
In an automotive vehicle, the combination comprising: a wheel chair having a pair of laterally spaced rotatable wheels disposed for motion along a first path of motion, each wheel having a rim and an opening defined by said rim; an elongated tubular support mounted in said vehicle at right angles to said first path of motion, said support being engaged with said pair of wheels and having a length greater than the distance between the laterally spaced wheels, and a plurality of longitudinally spaced openings therealong; a first body slidably mounted on the support so as to be movable therealong towards an adjusted position; an arm carried by the first body so as to be receivable in the opening of the rim of the first of said wheels to prevent motion thereof with respect to the support and pin means carried by the body so as to be receivable in a selected opening of the support to releasably prevent motion of the body along the elongated support; a second body slidably mounted on the support so as to be movable toward an adjusted position, an arm carried by the second body so as to be receivable in the opening of the rim of the second of said wheels to prevent motion thereof with respect to the support, and pin means carried by the second body to be receivable in a second selected opening of the support, whereby the arm carried by the first body and the arm carried by the second body cooperate in engaging the wheels to prevent motion of the wheel chair with respect to the support.
Claim 9
Dependent Claim
269 words
In an automotive vehicle, the combination comprising: a wheel chair having a pair of laterally spaced rotatable wheels disposed for motion along a first path of motion, each wheel having a rim and an opening defined by said rim; an elongated tubular support mounted in said vehicle at right angles to said first path of motion, said support being engaged with said pair of wheels and having a length greater than the distance between the laterally spaced wheels, and a plurality of longitudinally spaced openings therealong; a first body slidably mounted on the support so as to be movable therealong towards an adjusted position; an arm carried by the first body so as to be receivable in the opening of the rim of the first of said wheels to prevent motion thereof with respect to the support and pin means carried by the body so as to be receivable in a selected opening of the support to releasably prevent motion of the body along the elongated support; a second body slidably mounted on the support so as to be movable toward an adjusted position, an arm carried by the second body so as to be receivable in the opening of the rim of the second of said wheels to prevent motion thereof with respect to the support, and pin means carried by the second body to be receivable in a second selected opening of the support, whereby the arm carried by the first body and the arm carried by the second body cooperate in engaging the wheels to prevent motion of the wheel chair with respect to the support.
