发明名称 Bowling ramp attachment for wheelchairs
摘要 A bowling ramp attachment for wheelchairs. The ramp attachment includes a ramp in the form of a pair of spaced rod members which extend in an inclined manner from the seat area of the wheelchair to the floor. The ramp is slidingly attached to the wheelchair so as to be selectively movable across the front of the wheelchair. A pair of vertically extending posts are releasably clamped to the front frame members of the wheelchair. A cross bar is slidingly carried by the posts so as to be movable laterally across the front of the wheelchair. The cross bar is slidingly attached to the ramp to enable the ramp and the cross bar to be selectively positioned across the front of the wheelchair for directing a bowling ball in a variety of paths toward the bowling pins.
