Hand-held coating dispensing device
View Patent ↗A hand-held, electrostatically- and/or compressed gas-aided coating material dispensing device comprises a barrel and a handle extending downward from the barrel. The handle includes a module selected from modules having a number of different characteristics for coupling sources of coating material, compressed gas and/or electrical supply to the coating material dispensing device.
1. A hand-held, electrostatically-aided coating material dispensing device comprising
a barrel and
a handle extending generally away from the barrel to a distal end remote from a junction of the barrel and the handle, user-selectable modules adapted to be removably attached at the distal end of the handle, the user-selectable modules comprising:
a first module including a compressed gas-driven dynamoelectric machine, a compressed gas input port and a first electrical output port;
a second module including a battery and a second electrical output port;
and wherein the user is able to select at least one of the modules.
2. The coating material dispensing device of claim 1 further including a third user-selectable module including a fuel cell and an electrical output port.
3. The coating material dispensing device of claim 1 further including an inverter and multiplier.
4. The coating material dispensing device of claim 1 wherein the first module including a compressed gas-driven dynamoelectric machine, a compressed gas input port and an electrical output port comprises an air turbine coupled to the compressed gas input port.
5. The coating material dispensing device of claim 1 wherein the first module including a compressed gas-driven dynamoelectric machine, a compressed gas input port and an electrical output port further includes a port for supplying coating material to the coating material dispensing device, a line drawn through the compressed gas input port and the port for supplying coating material to the coating material dispensing device extending generally in the same direction as a longitudinal extent of the barrel.
6. The coating material dispensing device of claim 1 wherein the first module further includes a port for the supply of coating material to the coating material dispensing device, a line drawn through the compressed gas input port and the port for the supply of coating material to the coating material dispensing device extending in a direction other than a longitudinal extent of the barrel.
