Abstract
A holder for a coin-operated carwash wand containing a spring-biased, friction brake triggered by the pressure of fluid jetting from the wand. The brake prevents the wand or gun from being inadvertently jetted out of the holder should the user mistakenly insert his coins before the gun is removed from the holder. The frictional resistance engagement of the brake is sufficient to overcome the jetting force but is low enough to allow the user to pull the gun out of the holder even when the brake is on. The holder is also spring-mounted to its wall bracket so that it can rotate 90.degree. in the event the wand hose becomes snagged on a portion of the automobile being serviced, thus allowing the wand to be pulled out of the holder rather than having the holder ripped off the wall or the hose system otherwise damaged.
Claims13
A holder system for a car wash gun, having a handle, a shaft and a fluid nozzle, for washing cars and other vehicles and the like with a fluid jetting action from the gun, comprising:
- support means for holding and supporting the gun when out of use;
- movable brake means associated with said support means for moving into and out of braking engagement with the gun when in the holder;
- and
- force sensing and applying means associated with said support means and said brake means for detecting when fluid is flowing from the gun when the gun is in said support means and for actuating said movable brake means against the gun to prevent jetting of the gun from said support means if and when the fluid jetting action occurs when the gun is in said support means.
A method of safety holding a car wash gun, having a handle, a shaft and a fluid nozzle, for washing cars and other vehicles and the like with a fluid jetting action from the gun, comprising the following steps:
- (a) providing a support means for holding and supporting the gun when out of use;
- (b) providing a movable brake means associated with said support means for moving into and out of braking engagement with the gun when in the support means;
- and
- (c) sensing and detecting when fluid is flowing from the gun while the gun is in said support means;
- and
- (d) actuating said movable brake means against the gun to prevent jetting of the gun from said support means if and when the fluid jetting action occurs when the gun is in said support means.
