Inverted spray paint system using compressed air

摘要

A spray paint system for spraying a horizontal surface having a frame supporting an inverted elongated rigid container configured to hold a paint formulation that is pressurized with a pumping device partially located within the container where the frame has at least one wheel to allow a user to roll the system along a horizontal surface while spraying paint through a removable spray tip. This system can be used to mark a horizontal surface with precise and clear writing of lines, letters or symbols.

主权项

1. An inverted spray paint system comprising, in combination, the following;
a) a rigid telescoping frame having a single handle at one end and separated by a longitudinal length from a single wheel at the opposite end of the frame in a first position defining a distance between the handle and the wheel, wherein the frame is configured to extend the longitudinal length when in a second position such that the distance between the handle and the wheel is increased in a longitudinal direction, where the frame has no other wheels connected thereto; b) a paint bottle having a first and second connector, where the bottle is removably mounted to the frame and having a paint reservoir configured to withstand an internal pressure of 60 psig; c) a pump assembly in fluid communication with the paint bottle through the first connector, wherein the pump assembly comprises a pressure reservoir configured to withstand an internal pressure of 60 psig and to directly supply compressed gas through the first connector to pressurize the paint bottle; d) a pressure gauge attached to the reservoir and configured to monitor the internal pressure of the reservoir; e) a pressure hose connecting the pressure reservoir and the paint bottle through the first connector and configured to transmit only compressed gas from the reservoir into the bottle; f) a removable spray nozzle in fluid communication with and connected to the paint bottle through the second connector; and g) a trigger mounted on the frame and operably connected to a valve in fluid communication with the nozzle and the paint bottle wherein the handle is configured for grasping and holding by a user's hand and to allow the user to operate the trigger without removing the user's hand from the handle and wherein the rigid telescoping frame when in the first position allows a user to hold the spray paint system in a position above the ground where the single wheel is not touching any surface and to point the spray system at a surface to be painted.
