Abstract
A safety control grip brake for wheelchairs comprised of an internal steel sleeve adapted for rotatable coupling with an existing handle of a wheelchair. A steel spring coil is coupled with the internal steel sleeve. The steel spring coil applies a clockwise/counter clockwise tension on the internal steel sleeve. An outer hand grip is adapted for securement over the internal steel sleeve. The first end of the outer hand grip couples with the second end of the steel spring coil, and the second end of the outer hand grip is connected to a flanged pulley. The center bearing of the flanged pulley is secured to the internal steel sleeve. A steel cable is secured to the flanged pulley and extends down a frame of the wheelchair and is secured thereto by brackets. A brake mechanism is secured to the steel cable and couples with a wheel of the wheelchair to limit or stop the rotation of the wheel.
