Abstract
An apparatus for joining an axle tube to a wheelchair frame includes a body coupled to the wheelchair frame by a coupling. An opening in the outer surface of the body is shaped and dimensioned to receive a projection on the axle tube to form a joint between the axle tube and the body. Alternatively, a joint may be formed by an opening in the outer surface of the axle that is shaped and dimensioned to receive a projection on the body. A wheelchair having a pair of spaced side frames has a body coupled to each of the side frames. An opening in the outer surface of each body is shaped and dimensioned to receive a projection on an axle tube to form a joint between the axle tube and each body. A pair of wheels each has an axle received by the axle tube.
Claims25
A mounting assembly for joining a wheel to a wheelchair frame, comprising:
- an axle tube having a projection thereon;
- a body having an opening therein, said opening being shaped and dimensioned to receive said projection to form a joint whereby said axle tube cannot rotate relative to said body;
- and
- a coupling for coupling said body to the wheelchair frame.
An apparatus for joining an axle tube to a wheelchair frame, comprising:
- a tube having a projection thereon, said projection being a rigid, laterally extending tenon;
- a body having an outer surface and an opening in said outer surface, said opening being shaped and dimensioned to receive said projection to form a joint, said opening further being a mortise, said tenon and said mortise being in the shape of a dovetail;
- and
- a coupling for coupling said body to a wheelchair frame.
A mounting assembly for joining an axle tube to a wheelchair frame, comprising:
- a body having an outer surface and a projection on said outer surface;
- an axle tube defining an opening, said opening being shaped and dimensioned to receive said projection to form a joint whereby said axle tube cannot rotate relative to said body;
- and
- a coupling for coupling said body to the wheelchair frame.
An apparatus for joining an axle tube to a wheelchair frame, comprising:
- a body having an outer surface and a projection on said outer surface, said projection being a rigid, laterally extending tenon;
- a tube defining an opening, said opening being shaped and dimensioned to receive said projection to form a joint, said opening further being a mortise, said tenon and said mortise having mating dovetail shapes;
- and
- a coupling for coupling said body to a wheelchair frame.
A mounting assembly for joining a wheel to a wheelchair frame, comprising:
- an axle tube having an outer surface and a tongue on said outer surface of said axle tube;
- a support having a seat upon which said axle tube may rest and a groove shaped and dimensioned to receive said tongue to form a joint between said axle tube and said support, said support defining a first clamp part;
- and
- a second clamp part being removably attachable to said first clamp part so as to form a clamp, said first and second clamp parts each having a saddle shaped and dimensioned to receive a portion of the wheelchair frame, said clamp being adjustable relative to the wheelchair frame.
An apparatus for joining wheels to a wheelchair having laterally spaced side frames, said apparatus comprising:
- a rigid, elongate, laterally extending, cylindrical axle tube having opposite ends and an outer cylindrical surface;
- a rigid, laterally extending tenon on said outer cylindrical surface of said axle tube, said tenon extending from one said end of said axle tube to the other said end of said axle tube, said tenon having a dovetail shape;
- a pair of rigid, rectangular shaped bases, each said base having an upper end and a lower end, said upper end of each said base forming a carriage having a seat upon which said axle tube may rest and a mortise shaped and dimensioned to receive said tenon to form a joint between said axle tube and each said base, said lower end of each said base defining an upper clamp part having a saddle shaped and dimensioned to receive a portion of a respective one of the wheelchair side frames;
- and
- a pair of lower clamp parts, each said lower clamp part having a saddle shaped and dimensioned to receive a portion of a respective one of the wheelchair side frames, each said lower clamp part being removably attachable to said upper clamp part of a respective one of said bases so as to form a pair of clamps, each said clamp being adjustable for bracing each said base to a respective one of the wheelchair side frames.
A wheelchair comprising:
- a frame;
- an axle tube;
- a projection on said axle tube, said projection extending about a portion of said axle tube and not entirely about said axle tube;
- a body coupled to said frame, said body having an outer surface and an opening in said outer surface supported by said frame, said opening being shaped and dimensioned to receive said projection to form a joint between said axle tube and said body.
A mounting assembly for joining wheels to a wheelchair frame, comprising:
- an axle tube having opposite ends;
- a body adapted to be supported by the wheelchair frame;
- a projection on said axle tube, said projection extending from one said end of said axle tube to the other said end of said axle tube;
- and
- an opening in said body, said opening being shaped and dimensioned to receive said projection to form a joint.
