Safety control grip brake for wheelchairs

A safety control grip brake in combination with a wheelchair of the type having a frame and a handle and an axle with a plurality of wheels for providing a mechanical braking device for the wheelchair that gives a user better control comprising, in combination:

• an internal steel sleeve having a first end and a second end, the internal steel sleeve being adapted for rotatable coupling with the handle of the wheelchair, the second end having a protrusion extending outwardly therefrom;
• a steel spring coil having a first end, a second end, and an intermediate circular portion therebetween, the first end coupled with the protrusion of the internal steel sleeve, the steel spring coil applying a clockwise/counter clockwise tension on the internal steel sleeve;
• an outer hand grip adapted for securement over the internal steel sleeve, the outer hand grip coupling with the second end of the steel spring coil;
• a spring-biased push button locking mechanism secured to the outer hand grip, the spring-biased push button locking mechanism having an end portion extending inwardly through the outer hand grip to engage an aperture formed within the steel sleeve thereby allowing the user to lock the outer hand grip in place;
• a flanged pulley adapted for rotatable coupling with the handle of the wheelchair, the flanged pulley being connected to the second end of the outer hand grip, the enter bearing of the flanged pulley being secured to the second end of the internal steel sleeve, the flanged pulley having an outer housing secured thereover to the first end of the internal steel sleeve, the outer housing having an aperture formed through a lower portion thereof;
• a steel cable having a first end, a second end, and an intermediate extent therebetween, the first end being secured to the flanged pulley, the intermediate extent extending outwardly of the aperture in the outer housing and extending down the frame of the wheelchair and secured thereto by brackets;
• a double arm adjustable brake having a first end, a second end, and an intermediate extent therebetween, the first end secured to the second end of the steel cable, the intermediate extent being pivotally secured to the frame of the wheelchair adjacent to one wheel and the axle thereof, the second end having a brake pad disposed thereon;
• and
• a steel brake plate coupled with the axle of the wheelchair adjacent to the one wheel thereof, the steel brake plate biasing towards the wheel when pressured by the second end of the double arm adjustable brake to limit or stop the rotation of the wheel.
