Abstract
A self-contained power painting system is provided in which a battery operated motor and pump are contained in a lid for a paint reservoir, and that entire unit is adapted to be carried on a user by a strap or belt. A paint applicator, such as a brush or roller, is connected to the pump by a flexible conduit and includes a switch activator at the applicator to permit the user to selectively control operation of the pump and to move about freely while painting without being emcumbered by a relatively immobile paint reservoir or power source connection through extension cords.
Claims20
A self-contained, power painting system comprising:
- a paint reservoir including a bottom, at least one retaining wall extending upwardly rom said bottom, and a top edge distal from said bottom;
- a paint supply means comprising a power source, an electric motor energized by said power source, and a pump driven by said motor for pumping paint from said reservoir;
- housing means for enclosing said paint supply means, said housing means including a top wall, at least one side wall and a bottom wall;
- an applicator means for receiving paint pumped from said reservoir and for applying paint to a surface;
- delivery conduit means for carrying said paint from said paint supply means to said applicator means;
- said paint reservoir and paint supply means being operatively joinable as a unit so that said bottom wall and a major portion of said at least one side wall of said housing extend downwardly into said reservoir below said top edge thereof;
- and
- carrying means secured to said unit for permitting passive attachment of said unit to a user of said painting system, and for causing said unit to accompany the suer during operation of the system;
- wherein said power source comprises at least one battery;
- wherein said paint supply means further includes a manually operable electrical switch means for selectively energizing said motor;
- wherein said switch means comprises a manually operable vented bulb at said applicator means, said bulb having at least a portion thereof formed from a flexible material and connected by a second, air filled conduit to said paint supply means, and an electrical switch at said paint supply means having a movable contact engageable by a flexible diaphragm, which diaphragm communicates at one side with said second conduit, such that manual depression of said flexible portion of said bulb results in deflection of said movable contact to close a circuit normally opened by said switch.

A self-contained power painting system comprising:
- a paint reservoir comprising a walled container having a large top opening at a top edge thereof closeable by means of a removable cover;
- a pain supply means comprising a battery power supply, an electric motor energized by said battery power supply through an electric circuit, a pump driven by said motor and electrical switch means in said circuit to control energization of said motor;
- said removable cover comprising housing means for enclosing said paint supply means, said housing means including a top wall, at least one side wall and a bottom wall;
- said paint reservoir and paint supply means being operatively joinable as a unit so that said bottom wall and a major portion of at least one side wall of said housing extend downwardly into said reservoir below said top edge;
- an applicator means for receiving paint pumped from said reservoir and for applying paint to a surface;
- flexible tube delivery conduit means for carrying said paint from said paint supply means to said applicator means;
- activation means for said electrical switch means comprising a manually operable vented bulb at said applicator means, said bulb having at least a portion thereof formed from a flexible material and connected by a second, air filled conduit to said paint supply means, said electrical switch means at said paint supply means having a movable contact engageable by a flexible diaphragm, which diaphragm communicates at one side with said second conduit, such that manual depression of said flexible portion of said bulb results in deflection of said movable contact to close a circuit normally opened by said switch;
- and
- carrying means secured to said unit for permitting passive attachment of said unit to a user of said painting system, and for causing said unit to accompany the suer during operation of the system.
