Abstract

A back-carried paint sprayer including a sprayer assembly and a harness assembly. The sprayer assembly includes a container that stores a colored substance in liquid state, wherein said colored substance is moved by means of a motorized pump powered by a rechargeable battery housed in a bottom side of the container. The motorized pump is actuated by means of a spray gun that includes extension wands to reach high, low, and recessed areas when painting. The colored substance that is moved by the motorized pump that flows through a hose connected to the spray gun is regulated by means of a prime valve as the user may consider appropriate. The sprayer assembly is attached to the dorsal of a safety harness by means of a support assembly, allowing the user to be secured and preventing the user from falling when painting in dangerous places.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paint sprayer and, more particularly, to a back-carried paint sprayer that includes a safety harness with a backpack paint sprayer attached to the rear side thereof, wherein the paint sprayer has a motorized pump powered by a rechargeable battery. 2. Description of the Related Art Several designs for back-carried paint sprayers have been designed in the past. None of them, however, include a paint sprayer container attached to the rear side of a safety harness, wherein the paint sprayer container includes a spray gun with detachable extension wands and a motorized pump powered by means of a rechargeable battery allowing the paint sprayer device to be portable. Applicant believes that a related reference corresponds to U.S. Pat. No. 5,248,089 issued for combination carrying case/paint container. Applicant believes that another related reference corresponds to U.S. Pat. No. 4,651,903 issued for motorized pump pressurized liquid sprayer. None of these references, however, teach of a back-carried tank with a motorized pump that supplies paint to a spray gun device, wherein the tank apparatus includes a shoulder harness and extension wands that are stored in a receptacle integrally formed on one side of the tank. Other documents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention. SUMMARY OF THE INVENTION It is one of the objects of the present invention to provide a portable paint sprayer device that is rechargeable by means of a battery. It is another object of this invention to provide a safety device when painting inaccessible areas. It is still another object of the present invention to provide a device with regulable pressure and extension wands for the spray gun. It is yet another object of this invention to provide such a device that is inexpensive to implement and maintain while retaining its effectiveness. Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon. BRIEF DESCRIPTION OF THE DRAWINGS With the above and other related objects in view, the invention consists in the details of construction and combination of parts as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which: FIG. 1 represents an operational view of an exemplary embodiment of the present invention 10, wherein the sprayer assembly 20 is attached at the dorsal of the harness assembly 40 to be carried by the user. FIG. 2 shows an isometric view of the present invention 10, wherein the spray gun 28 may be actuated by means of a trigger where the outlet pressure of the paint contained into the container 22 is regulable by means of the prime valve 36 coupled to the housing 38. FIG. 3 illustrates a front view of the sprayer assembly 20, wherein extension wands are mounted on the container 22, thereby the user may attach each wand of the extension wands to the spray gun for high, lo, or recessed areas. FIG. 4 is a representation of an exploded view of the present invention 10, wherein the motorized pump 32 and the battery 34 are housed inside the housing 38 allowing the present invention to be portable and carried by means of the support assembly 60. DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION Referring now to the drawings, where the present invention is generally referred to with numeral 10, it can be observed that it basically includes a sprayer assembly 20 and a harness assembly 40. It should be understood there are modifications and variations of the invention that are too numerous to be listed but that all fit within the scope of the invention. Also, singular words should be read as plural and vice versa and masculine as feminine and vice versa, where appropriate, and alternative embodiments do not necessarily imply that the two are mutually exclusive. Sprayer assembly 20 includes a container 22, a lid 24, a hose 26, a spray gun 28, extension wands 30, a motorized pump 32, a battery 34, a prime valve 36, and a housing 38. In an exemplary embodiment, the container 22 may be a box-shaped receptacle adapted to store a colored substance in a liquid phase, wherein the container 22 may include an opening in a top side thereof where the lid 24 may be removable attachable to cover and protect the colored substance. As FIG. 2 depicts. Nonetheless, it should be considered that the opening of the container 22 may be placed on a top periphery of the container 22 wherein a slanted opening may be suitable to add the colored substance. In a suitable embodiment, the container 22 may be made of a plastic material, a metal material or any other
