Description




FIELD OF THE INVENTION




The present invention relates generally to an apparatus for painting and in particular to a paint pad on which the mounting plate carries a paint pad on one side and has projections on the other side to which a handle is removably attached to the mounting plate.




BACKGROUND OF THE INVENTION




Currently, painters use brushes or rollers to paint large wall surfaces in an efficient manner. However, using brushes or rollers to paint to the edge of a wall surface, without painting the adjacent wall surface is extremely difficult, if not impossible. These paint applicators necessitate frequent renewal by reapplying the tape to the surface adjacent the surface being painted or require re-painting of the edge of the surface being painted, at considerable expense and effort. Several devices have been developed to solve this problem.




One device is a paint pad that is coupled to a flat mounting plate. The mounting plate has four spacer means that extend beyond the mounting plate, each spacer means extends beyond at least two edges of the paint pad. A disadvantage of such device is that mounting plate substantially covers the spacer means, thus making it very difficult to sufficiently clean the spacer means if paint is picked up by the spacer means, which prevents the spacer means from rolling if desired and causes the spread of paint on the spacer means to spread to the adjacent surface.




Another device is a coating pad device having projections on one side of the pad for locking the shaft of the handle in one of three positions. One disadvantage of such device is a lack of means for neatly painting the edges between two surfaces. Another disadvantage of such device is a lack of flexibility for the paint handle's motion, since the handle is locked in one of only three positions. A further disadvantage of such device is that the support shaft has to be snapped into the locking projections, which would be difficult if projections had paint on their surfaces, particularly when the paint pad was removed and replaced with a new paint pad. Yet a further disadvantage of such device is a lack of a projection on one side with the locking projections, (a stop block) which would rest directly at the end of the support shaft and restrict the motion of the handle along its axis with respect to the pad.




Another type of device uses a flat pad having a fixed blade along one edge of the pad. During loading of the pad, paint is unavoidably applied to the edge. Paint must then be wiped from the edge before applying paint to the adjacent surface. The result is that the paint operation becomes messy and wasteful.




The previous devices do not provide for a clean painted line between adjacent surfaces at the same time allowing quick and efficient access to spacer for cleanup and allowing for a fully rotatable handle coupled to a paint pad, wherein the paint pad does not slip perpendicular with respect to the motion of applying paint with the paint pad.




SUMMARY OF THE INVENTION




The present invention provides a paint pad apparatus for applying paint to a surface comprising: a mounting plate, preferably in the shape of a rectangle, having a top and a bottom face; a paint pad attached to the bottom face of the mounting plate; a plurality of upwardly extending projections attached along the top face of the mounting plate, the projections having internal cavities capable of supporting an end portion of a shaft of a handle; a stop block projection attached along the top face of the mounting plate, to stop the end portion of the shaft of the handle; and a plurality of spacers rotatably attached along the top face of the mounting plate for maintaining the paint pad apparatus at a uniform distance from a surface adjacent the surface being painted. At least two spacers extend outwardly beyond at least two sides of the mounting plate and at least two spacers extend outwardly beyond one side of the mounting plate. The alignment projections, the upwardly extending projections, and the stop block projection are preferably integrally attached to the top surface of the mounting plate.




In a further embodiment of the invention the paint pad apparatus comprises at least two alignment projections attached along the top face of the mounting plate to allow alignment of an end portion of a shaft of a handle.




In yet a further embodiment the paint pad apparatus comprises a plurality of tabs along the bottom face of the mounting plate, the tabs extend inwardly along at least two opposing peripheral edges of the mounting plate to allow mounting of the paint pad.




These and other features, aspects, and advantages of the present invention will become better understood with regard to the following detailed description and accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION




In accord with the present invention a generally flat pad is provided, adapted to carry a small amount of paint and apply it to a surface or to advance paint already on a surface. The paint pad includes those pads commercially available and known as “brush pads,” “pile brush pads,” and “pile brushes.”




With reference to

FIGS. 1-6

, a paint pad apparatus


8


comprises a mounting plate


10


having a top surface


12


and a bottom surface


14


. The mounting plate


10


is typically made of plastic, such as polypropylene, polyethylene, nylon, acetal, Kapetal, or m27. The mounting plate is preferably made from a material that has some rigidity so that when pressure is applied to the plate during the painting application, the plate is able to equally distribute the pressure over the entire plate. The top surface


12


has at least one alignment projection


20


extending upwardly from the top surface


12


. Preferably, there are at least two alignment projections


20


extending upwardly from the top surface


12


, the projections


20


aligned adjacent one another and having a space between each other about the width of a shaft


32


of a handle


37


.




The top surface


12


also has a plurality of upwardly extending projections


22


,


24


,


26


, and


28


. The upwardly extending projections


22


and


24


are aligned along one axis of the mounting plate


10


, the upwardly extending projections


26


and


28


are aligned along the other axis of the mounting plate


10


, i.e., the axis of the extending projections


26


and


28


is at an angle of 90° with respect to the axis of the extending projections


22


and


24


. Both axes of the upwardly extending projections


22


,


24


,


26


, and


28


lie preferably along the center of the mounting plate


10


. The plurality of upwardly extending projections


22


,


24


,


26


and


28


have preferably a plurality of support projections


54


on their sides. The support projections


54


provide an additional rigid support to the projections


22


,


24


,


26


, and


28


to prevent them from breaking off of the mounting plate


10


.




Each upwardly extending projection has an internal cavity to support a shaft


32


of a paint handle


37


. The alignment projections


20


allow for alignment of the shaft


32


of the handle


37


prior to the shaft's entrance into and through the internal cavities of the upwardly extending projections


22


and


24


. The top surface


12


also has a stop block projection


38


which stops an end of the shaft


32


after the shaft has entered the upwardly extending projections


22


and


24


. The stop block projection


38


prevents shifting of the mounting plate


10


with respect to the paint handle


37


, while allowing the shaft


32


to be freely rotatable with respect to the mounting plate


10


.




The top surface


12


of the mounting plate


10


also has a plurality of spacers


30


rotatably mounted on the top surface


12


. Preferably there are four spacers


30


for maintaining the paint pad apparatus


8


at a uniform distance from a surface adjacent the surface being painted, so that when the paint pad


39


engages the paint, the borderline of the paint applied by the paint pad


39


is close to an edge where the adjacent surface and the surface being painted meet. The spacers


30


have preferably flat edges and are made of plastic, such as nylon or TEFLON (manufacture by DuPont, USA), although they may be made of other materials such as rubber. At least two spacers


30


extend outwardly beyond at least two sides of the mounting plate and at least two spacers


30


extend outwardly beyond only one side of the mounting plate. The extension of the spacers


30


is about 0.05 inches from the sides of the mounting plate. The purpose of the spacers is to keep paint from getting on the surface adjacent the surface being painted. Preferably, the mounting plate


10


is of rectangular shape and the spacers


30


are located at the corners of the rectangle. In another embodiment of the present invention, the shaft


32


of the handle


37


enters through the internal cavities of the upwardly extending projections


26


and


28


, whereby the paint pad apparatus


8


is turned 90° allowing for greater flexibility when painting a surface necessitates a narrower paint pad.




Referring to

FIG. 3

, the bottom surface


14


supports a paint absorbent pad


39


. The paint absorbent pad


39


is mounted to the bottom surface


14


of the mounting plate


10


by snapping the peripheral edge


40


of the pad


39


under a plurality of tabs


16


extending outwardly from the bottom surface


14


. The tabs


16


extend along at least two opposing sides of the peripheral edge of the mounting plate


10


. Preferably there are three tabs


16


along one side of the mounting plate


10


and three tabs


16


along the opposing side of the mounting plate


10


. The mounting plate


10


preferably has a push out hole


48


located in the center of the plate


10


for allowing the pad


39


to be pushed out and replaced with a new pad.




Referring to

FIGS. 3 and 4

, the paint pad


39


is shown as preferably comprising a support layer such as a flexible plastic backing


46


having a peripheral edges


40


, a padding layer such as a foam layer


42


, either open or closed cell foam, preferably composed of a polyurethane or polyester and bristles or pile and the like


44


suitably attached to the foam layer


42


, e.g., by flocking. Preferably the pad uses bristles or other fibers to absorb and spread the paint, however, pile fabric or other pile may be used such as suitable for holding and dispensing a quantity of paint. If bristles are used it is preferred they be made of nylon or a natural material such as mohair. The paint pad


39


has preferably the same configuration as the mounting plate


10


, e.g., a rectangular shape, which allows for efficient mounting of the paint pad


39


to the mounting plate


10


. The peripheral edges


40


are seen to have four substantially straight sides, in this case in the shape of a rectangle. The peripheral edges of the paint pad


39


are pressed under the plurality of tabs


16


extending from the bottom surface


14


of the mounting plate


10


to mount the paint pad


39


to the mounting plate


10


. The tabs


16


also press into the padding layer


42


which also hold the pad


39


to the mounting plate


10


. When mounting the pad


39


to the plate


10


, the peripheral edges of the pad


39


are placed under at least two opposing tabs


16


and the pad can slide past the remaining tabs


16


.




The paint handle


37


comprises a first end of a shaft


32


, which is inserted into the internal cavities of the upwardly extending projections


22


,


24


or


26


and


28


and is rotatable. The shaft is preferably made of metal wire having a round cross-section, although a strong plastic may be substituted for the metal. The paint handle


37


further comprises a second end


34


of the shaft which is attached to a grip


36


. The grip has two ends, on a first end the grip


36


has a substantially cylindrical, threaded internal cavity


52


to allow for threading an extender to the paint handle


37


, in this way, surfaces such as ceilings can be reached with the apparatus. On the second end of the grip


36


are located a plurality of prongs


50


. The prongs


50


allow the apparatus to be put down without having to touch the ground, for example, a prong


50


is able to hook over the edge of a paint can. Therefore, when the pad


39


is used the paint on the pad will not pick up unwanted debris. The grip


36


is preferably made of plastic, such as polypropylene, polyethylene, or nylon, although it may be made of other materials such as rubber. The grip


36


can also be texturized to provide a non-slip surface.




Although the foregoing invention has been described in some detail by way of illustration and example for purpose of clarity and understanding, it will be obvious that various modifications and changes which are within the knowledge of those skilled in the art are considered to fall within the scope of the appended claims.
