A foldable wheelchair includes a cross brace assembly having first and second brace members pivotally secured to one another. First ends of the brace members are clamped to respective side frames of the wheelchair.

US Classification:

2802501

Abstract:

The present invention is directed to a lightweight wheelchair having adjustable wheel camber, adjustable toe-in/toe-out positions, and front-to-rear adjustment of the wheel assembly relative to the frame. The wheel camber is changed by removable camber tubes having plugs in opposite ends with different angular relationships. The camber tube is removed from an axle tube, rotated through one hundred eighty degrees, and reinserted to change the wheel camber. The location of the angular recesses in the camber plugs addresses minor toe-in/toe-out adjustments while rotation of an axle tube provided with indicia assures that proper toe-in/toe-out adjustment is provided for larger wheel camber adjustments. The front to rear location of the wheels relative to the frame can be adjusted via a single fastener on each side. Moreover, the track width of the rear wheels can be adjusted in response to the change in wheel camber.
