发明名称 Device for adjusting the legs of adjustable wheelchairs
摘要 A generally inverted L-shaped device for elevating or lowering the legs of a wheelchair which is provided with adjustable legs. The device has a first elongated member having a free end and a second elongated member having a free end formed angularly with the first elongated member. A positioning bracket is secured to the first elongated member for releasable engagement to either side of the wheelchair as a fulcrum and a cross member is transversely secured at the free end of the first elongated member for supporting either leg of the wheelchair thereon. A pair of generally vertical, upwardly extending arms at the ends of the cross member serve to prevent the legs from sliding off when the device is used to raise or lower each leg to any desired convenient height.
