Patent Application
20170136488
The present invention relates generally to surface coating applicators, and more particularly, relating to pressurized paint applicator device.
Pressurized surface coating applicator devices are known. Examples of such devices are described in U.S. Pat. Nos. 4,611,940; 3,602,601; 2,677,839; and 2,627,620 each of which are incorporated herein in their entirety by reference. While the devices heretofore fulfill their respective, particular objectives and requirements, there exists and need for an improved pressurized surface coating device, which substantially departs from the prior art, and in doing so provides an apparatus primarily developed for the purpose of cutting in paint edges.
The present invention provides an improved pressurized paint applicator device that is particularly useful in cutting in paint edges.
In general, in one aspect, a pressurized paint applicator device is provided. The pressurized paint applicator device includes an applicator having a top side and a conically-shaped bottom side and at least one distributor tube having an open end that is directed toward the bottom side of said applicator.
In general, in another aspect, a pressurized paint applicator device is provided. The pressurized paint applicator device includes an applicator with a top side and a conically-shaped bottom side. At least one distributor tube has an open end that is directed toward the bottom side of the applicator. The device further includes a pressure tank and an air pump connected to the pressure tank and operable to pump air into the pressure tank. A supply tube is connected at one end to the pressure tank and is connected at its opposite end to the at least one distributor tube. A valve is connected to supply tubing and is operable to control a flow through the supply tubing. A bracket is rotatably connected to the top side of the applicator and a handle is pivotally connected to the bracket.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
Numerous objects, features and advantages of the present invention will be readily apparent to those of ordinary skill in the art upon a reading of the following detailed description of presently preferred, but nonetheless illustrative, embodiments of the present invention when taken in conjunction with the accompanying drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there are illustrated embodiments of the invention.
The following drawings illustrate by way of example and are included to provide further understanding of the invention for the purpose of illustrative discussion of the embodiments of the invention. No attempt is made to show structural details of the embodiments in more detail than is necessary for a fundamental understanding of the invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the invention may be embodied in practice. Identical reference numerals do not necessarily indicate an identical structure. Rather, the same reference numeral may be used to indicate a similar feature of a feature with similar functionality. In the drawings:

Referring now to the drawings, and more particularly to
With reference to
Handle 14 is an elongated extension-type handle have an adjustable length by extending or retracting handle portion 24 from handle portion 26. As further discussed below, the handle 14 is connected to the applicator 16 for manipulating the applicator in applying a coating to a surface. Supply tube 18 is connected at one end to the tank 12 and connected at its opposite end to the applicator 16 to deliver paint from the tank to the applicator for applying the paint to a surface. As shown, the supply tube 18 is extends within and through the entire handle 14, but it should be understood that the supply tube could extend exteriorly of the handle or interiorly along any desired length of the handle. As further shown in the illustrated embodiment, valve 28 is provided to control the flow of paint from the tank 12 to the applicator 16.

In use, it can now be understood, paint or other coating is placed into the tank 12 and air is pumped into the tank to pressurize the tank. In the illustrated embodiment, air is pumped into the tank 12 via manual pump 20. The pressure within the tank 12 causes paint to flow through the supply tubing 18 to the valve 28. Then operating the valve 28 allows the paint to flow into the distributor tubes 40 and 42, where the paint is discharged upon the applicator pad 54. After the paint is applied to the applicator pad 54, the pad is rotated about coupling 36 to position the coated portion of the pad away from the distributor tubes for application to a surface.
Alternative embodiments are possible. With reference to
The middle tank section 68 receives and holds a quantity of paint or other surface coating to be applied to a surface by fill opening 86 formed through the top of the tank 64 and sealed by cap 88. Supply tube 18 sealing extends through the side of the tank 64 and extends into and toward the bottom of tank section 68 to draw paint from tank section 68
Tank sections 66 and 70 are pressurized with air via an air pump 90 that is detachably connected to air valve stem 92, which communicates with the interior of the tank 64. Apertures 72 and 78 allow the air to communicate between tank sections 66, 68, and 70 so that tank section 68 is also pressurized. Tank 64 may be fitted with a pressure gauge 94 to indicate the pressure of the tank and may be fitted with a pressure release valve 96 that automatically operates to vent air from the tank in an over pressurized.
Pressure tank 64 may also be fitted with shoulder straps 98 and 100 that allow carrying the tank upon a user's back. Additionally, the pressure tank 64 may also include wheels 102 and 104 that allow rolling the tank across the ground.
A number of embodiments of the present invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, other embodiments are within the scope of the following claims.
