A wheelchair comprises a pair of frame members of one piece of solid material. A well indented into each frame member accommodates an axle for mounting a wheel therein. A pair of braces supports the frame members in a spaced-apart position and allows the frame members to be brought together. A vertical pivot pivotally mounts the brace members with respect to each other at a central portion of each brace member. Each brace member pivots with respect to a frame member about a vertical axis on an anchor. The other end of each brace member is releasably anchored to the frame member opposite the one to which the one end of the brace member is anchored. A brake on the frame moves against the wheels to lock them, and a hill holder connected to the brake prevents movement of the wheels in one direction. A brake handle is movable between at least two positions, a locking one and a hill holder one. The handle is mounted in an indentation on each frame member adjacent the well. The brake passes through the well upon movement of the handle to the locking position and the hill holder passes through the well upon movement of the handle to the hill holding position. Side members are mounted on the top of the frame members to extend either upward or outward from each frame member. There is also a foot rest housing, a telescoping section extending downward from the housing and a mounting bracket for mounting a foot rest on the telescoping section. A grip on the top part of the housing is connected to the telescoping section within reach of the user whereby pulling the grip raises the foot rest. A seat supporting the user between the frame members includes a platform mounted below the top of the frame. A pit is provided in the platform, and a cushion on the platform extends into the pit. The cushion is flush with the top of the frame members.
A wheelchair comprising a pair of frame members, each formed of one piece of material;
In a wheelchair having a pair of wheels and a pair of frame members, each frame member having wheel mounting means for supporting one wheel on each frame member, collapsible brace means connecting the frame members together and adapted to hold the frame members in an open position when the wheelchair is to be occupied and a collapsed position for storage of the wheelchair, each frame member being formed of one piece of material, the improvement comprising the provision of each frame member having well means indented into each, and the wheel mounting means mounts the wheel in the well means to minimize the width of the wheelchair and to prevent the wheels from throwing mud and water.
In a wheelchair having a pair of wheels and a pair of frame members, each frame member having wheel mounting means for supporting one wheel on each frame member, collapsible brace means connecting the frame members together and adapted to hold the frame members in an open position when the wheelchair is to be occupied and a collapsed position for storage of the wheelchair, each frame member being formed of one piece of material, the improvement comprising the provision of having the brace means comprising a pair of brace members;
In a wheelchair having a pair of wheels and a pair of frame members, each frame member having wheel mounting means for supporting one wheel on each frame member, collapsible brace means connecting the frame members together and adapted to hold the frame members in an open position when the wheelchair is to be occupied and a collapsed position for storage of the wheelchair, each frame member being formed of one piece of material, the improvement comprising the provision of:
In a wheelchair having a pair of wheels and a pair of frame members, each frame member having wheel mounting means for supporting one wheel on each frame member, collapsible brace means connecting the frame members together and adapted to hold the frame members in an open position when the wheelchair is to be occupied and a collapsed position for storage of the wheelchair, each frame member being formed of one piece of material, the improvement comprising the provision of having:
In a wheelchair having a pair of wheels and a pair of frame members, each frame member having wheel mounting means for supporting one wheel on each frame member, collapsible brace means connecting the frame members together and adapted to hold the frame members in an open position when the wheelchair is to be occupied and a collapsed position for storage of the wheelchair, each frame member being formed of one piece of material, the improvement comprising the provision of:
In a wheelchair having a pair of wheels and a pair of frame members, each frame member having wheel mounting means for supporting one wheel on each frame member, collapsible brace means connecting the frame members together and adapted to hold the frame members in an open position when the wheelchair is to be occupied and a collapsed position for storage of the wheelchair, each frame member being formed of one piece of material, the improvement comprising the provision of:
In a wheelchair having a pair of frame members, a seat between the frame members, and brace means between the frame members for supporting the frame members in a spaced apart, open position and allowing the frame members to be brought together to a collapsed position, the improvement comprising:
In a wheelchair having a pair of frame members and a main wheel mounted for rotation on each frame member, brace means attached to the frame members for separating the frame members, a seat between the frame members for supporting the user, brake means on the frame members movable against the wheel for preventing rotation of the wheels to brake the wheelchair, and hill holder means on the frame members for preventing movement of the wheels in one direction to allow wheelchair movement in the forward direction and to prevent movement of the wheelchair in the rearward direction, the improvement comprising the provision of:
In a wheelchair having a pair of frame members, brace means attached to the frame members for supporting the frame members in a spaced apart, open position, a seat between the frame members for supporting the user and a footrest attached to each frame member for supporting the user's foot, the improvement comprising:
In a wheelchair having a pair of frame members, brace means attached to the frame members for supporting the frame members in a spaced apart, open position, a seat between the frame members for supporting the user, a footrest attached to each frame member for supporting the user's feet, and footrest supporting means for supporting the footrest on the frame members, the improvement comprising:
In a wheelchair having a pair of frame members, a seat between the frame members, brace means between the frame members for supporting the frame members, a main wheel on each of the frame members for propelling the wheelchair and side members extending generally vertically from the frame members, the side members having a first set of edges on opposite sides of the side members and a second set of edges, each adjacent to an edge of the first set of edges, the improvement comprising:
In a wheelchair having a pair of frame members, brace members attached to the frame members for supporting the frame members and a seat between the frame members for supporting the user, the improvement in the seat comprising:
A method of collapsing a wheelchair having opposed frame members and a pair of brace members, pivotally connected to each other about a vertical axis, supporting the frame members in an open condition, each brace member being held to one frame member by a bracket and to the other frame member by an anchor, comprising:
