ABSTRACT:
A detachable and collapsible weather shield for a wheelchair may be user-disposed in a user-selected orientation. The weather shield includes first and second generally inverted "U"-shaped frames, in which the distal leg ends of the second frame are pivotally joined by a coupler to a leg portion of the legs of the first frame. A flexible moisture resistant canopy extends over at least the top portion of the frames and preferably also extends downward to also cover a portion of the legs. A releasable pivotable anchor is secured to one and preferably both wheelchair push arm regions, and permits releasably and rotatably attaching the distal leg ends of the first frame to the wheelchair. The anchor permits user-adjustment of the relative angular orientation of the first frame (and thus of the weather shield) and/or the vertical height (including complete removal) of the weather shield relative to the ground. The anchor unit may be manually operable, or may be motorized. If motorized, user-generated control signals may be wirelessly transmitted to a receiver associated with the motor, or hardwiring may be provided.
