Abstract
A hand-held powder spray gun includes a wand type handle that extends from the top of the handle and away from the rear of the gun, which provides for ergonomic operation of the gun. The wand handle can be converted to a pistol handle by removal of the handle from the gun body. The parts of the wand handle and the pistol handle are interchangeable to facilitate conversion and repair. The wand handle can be used with a diffuser having hose connections extending from the rear of the spray gun to make the gun easier to operate when held from above. A diffuser having hose connections at the bottom is also provided for use with a pistol type handle.
Claims28
A hand-held powder spray gun which comprises:
- a body having first and second ends;
- a diffuser for mixing powder with conveying air, the diffuser connected to the first end of the body and forming the inlet end of the gun;
- a barrel extending longitudinally along an axis from the second end of the body, the barrel providing a charging path for the powder;
- a sprayhead mounted on the barrel opposite the body, the sprayhead forming the outlet end of the gun;
- and
- a wand handle for grasping and operating the gun, the handle being attached to the body and extending upwardly from the body, the wand handle including a cable connection located adjacent to the gun body and extending toward the inlet end of the gun.
An assembly for converting the handle position of a hand-held spray gun for coating materials having a pistol handle assembly mounted to a gun body and extending downwardly from the gun body toward the rear of the gun, the pistol handle assembly including a pistol handle body, a trigger and a switch, the converting assembly comprising
- a wand handle assembly including a wand handle body for mounting to the gun body and extending upwardly from the gun body,
- means for mounting the trigger from the pistol handle body to the wand handle body, and
- means for mounting the switch from the pistol handle body to the wand handle body.
An assembly for converting the handle position of a hand-held spray gun for coating materials having a wand handle assembly mounted to a gun body and extending upwardly from the gun body, the wand handle assembly including a wand handle body, a trigger and a switch, the converting assembly comprising
- a pistol handle assembly including a pistol handle body for mounting to the gun body and extending downwardly from the gun body,
- means for mounting the trigger from the wand handle body to the pistol handle body, and
- means for mounting the switch from the wand handle body to the pistol handle body.
A hand-held spray gun for powder coating materials which comprises:
- a body having first and second ends;
- a barrel extending longitudinally along an axis from the second end of the body;
- a sprayhead mounted on the barrel opposite the body, the sprayhead forming the outlet end of the gun;
- a handle attached to the body for grasping and operating the gun, the handle including a cable connection located adjacent to the gun body and extending toward the first end of the gun body;
- and
- a diffuser for mixing powder coating material with conveying air, the diffuser being mounted at the first end of the body and forming the inlet end of the gun, the diffuser including a first hose connection for attachment to a powder coating material supply hose and a second hose connection for attachment to a conveying air supply hose, the first and second hose connections both extending from the end of the diffuser opposite the body, the first and second hose connections being substantially parallel to each other and substantially parallel to the longitudinal axis of the barrel of the gun.
A convertible hand held spray gun for coating materials, comprising:
- a barrel having a rearward end and a forward end;
- a sprayhead connected to the forward end of the barrel;
- and
- a kit comprising interchangeable pistol and wand handle bodies which are selectively mountable to the barrel, the pistol handle body being mountable with respect to the barrel to extend downwardly from the barrel, the wand handle body being mountable with respect to the barrel to extend upwardly from the barrel.
A method of converting a hand-held spray gun for coating materials between a wand style spray gun and a pistol style spray gun, which comprises the steps of
- providing a spray gun having a provided handle removably attached thereto, the provided handle being one of a wand handle and a pistol handle;
- removing the provided handle from the gun;
- and
- replacing the provided handle with a replacement handle, the replacement handle being the other of the wand handle and the pistol handle.
