Description




BACKGROUND OF THE INVENTION




This invention relates to a paint shield used in residential and commercial painting applications, and finds particular use with the application of paint by spraying.




When painting, it is obviously desirable that services which should not receive paint, do not receive paint. For that reason, paint shields have been developed over the years. One form of conventional paint shield includes a metal straight edge to which a handle, which runs generally parallel to the straight edge, is attached. This device is generally rigid, and does not allow for significant flexure for conforming with corners and other angular surface details during painting. Another type of conventional paint shield includes an elongated straight edge portion, having an elongated handle extending generally transversely with respect to the straight edge. However, this design also generally does not offer the flexibility needed for certain surface features.




Another problem with the prior art designs are that they do not offer a large enough shield to provide meaningful protection when paint is applied to a surface by spraying. Overspray from the sprayer must be blocked from application to surfaces which are not to be painted. Since the amount of overspray, and actual overspray area, vary depending on the situation, a significant amount of shielding is required in order to deliver an acceptable paint job.




Accordingly, a need exists for a paint shield which is versatile, flexible, durable, and which provides suitable shielding from paint over spray.




SUMMARY OF THE INVENTION




It is, therefore, an object of the invention to provide paint shield which can be used in a variety of painting applications.




Another object of the present invention is to provide a paint shield for use in spray painting applications.




A further object of the present invention is to provide a paint shield which readily conforms to corners, angles, and other features of surfaces being painted.




Yet another object of the present invention is to provide a paint shield which can be used to accommodate a variety of surface profiles, without requiring to be flipped over.




On the other hand, another object of the present invention is to provide, a paint shield which may be flipped over and continued to be used, if desired.




A further object of the present invention is to provide a paint shield which is lightweight and flexible, and yet sufficiently rigid for paint shielding purposes.




A still further object of the present invention is to provide a method for using a paint shield.




Another object of the present invention is to provide a paint shield which is durable and reusable.




An additional object of the present invention is to provide a paint shield which has a plurality of straight edge shields of variable lengths and inside and outside corner shields.




Another object of the present invention is to provide a paint shield which minimizes marring of freshly painted surfaces.




Generally, the present invention includes a e paint shield formed of a flexible plastic, such as high density polyethylene (HDPE), and which is formed generally in the shape of a T. The shield includes straight edges of varying and of variable lengths to allow the shield to be used for shielding a variety of straight surfaces. The shield also includes left and right hand inside corner shields, and left and right hand outside corner shields. Preferably, the shield includes radiused corners for the left and right hand outside corner shields for accommodating the slight radius typically found on sheet rock, plaster, etc., wall constructions.




The paint shield of the present invention is lightweight and relatively simple to manufacture. It is also durable and relatively easy to use, even for less experienced painters. Because of the flexibility inherent in the paint shield, it can be bent in order to conform to corners, particularly in situations where a small space is involved, such as in a closet, where a wall segment is shorter than the overall length of the desired straight edge.




The paint shield preferably includes a major portion, which has the longest straight edge, and a secondary portion which, together with the major portion, provides numerous hand-hold positions for holding by the painter during use. The secondary portion also provides the shields for left and right hand outside corners to facilitate painting of outside corners. Preferably, the juncture of the secondary portion and the major portion of the shield are radiused in order to improve durability and longevity of the shield by reducing the likelihood of cracks forming and propagating at such juncture.

DESCRIPTION OF THE PREFERRED EMBODIMENT




The accompanying drawings and the description which follows set forth this invention in its preferred embodiment. However, it is contemplated that persons generally familiar with painting and paint shields will be able to apply the novel characteristics of the structures illustrated and described herein in other contexts by modification of certain details. Accordingly, the drawings and description are not to be taken as restrictive on the scope of this invention, but are to be understood as broad and general teachings.




Referring now to the drawings in detail, wherein like reference characters represent like elements or features throughout the various views, the paint shield of the present invention is indicated generally in the figures by reference character


10


.




Turning to

FIG. 1

, paint shield


10


of the present invention is shown. Preferably, paint shield


10


is of a generally T shape and includes a major portion, generally


12


, to which a secondary portion, generally


14


, is integrally attached. In a preferred embodiment, paint shield


10


is formed from a sheet of high density polyethylene (HDPE) and is made of a thickness which generally provides sufficient rigidity for use as a paint shield, while maintaining the flexibility to allow the shield to be bent drastically (at least about ninety degrees) along the length of major portion


12


. In a preferred embodiment, the thickness of shield


10


is approximately {fraction (3/32)}


nd


to ⅛


th


inches. It is to be understood, however, that the shield


10


of the present invention is not limited to HDPE, and could be constructed of a variety of other materials.




Shield


10


is flexible, and is bendable to allow it to conform to a corner, such as corner


18


shown in

FIG. 4

, during painting. This feature of shield


10


finds particular use in small areas, such as closets, alcoves, etc., where a corner


18


′ prevents shield


10


from laying flat. A slight radius


19


(

FIG. 5

) is provided at the juncture of major portion


12


and secondary portion


14


to improve durability of the shield, and to reduce crack formation and propagation at such juncture and to closely accommodate the slight radius generally found on wall and other surface coverings.




Turning to

FIG. 2

, shield


10


is shown being used by the painter, generally P, and painting a vertical wall, generally W, surface, at the juncture, or corner,


20


of wall W with wall W′. The paint spray, generally S, emitted from gun, generally G, is directed against wall W, but blocked by major portion


12


of shield


10


from deposit on wall W′. In this instance, shield


10


is being held in a corner, generally


20


.




Because of the length of major portion


12


, which is


36


inches in one preferred embodiment, the painter is able to paint several feet of wall W at a time before being required to reposition shield


10


. It should also be noted from

FIG. 2

the location at which the painter is grasping shield


10


. Specifically, the painter is grasping left-hand outside corner shield


28


, while in

FIG. 4

, the painter is grasping an outside edge


30


of shield


10


. It should be noted in the

FIG. 4

illustration that shield


10


could be forced further downwardly into corner


18


by the painter using his or her hand or foot in order to conform shield


10


even more closely to corner


18


. This having been done, paint may be applied nearly up to corner


18


.




After paint has been applied to baseboard trim


32


as close as possible to corner


18


in the

FIG. 4

illustration, the shield


10


could then be removed, and repositioned such that end


30


of shield


10


abuts trim piece


32


and such that straight edge


34


of major portion


12


abuts trim piece


36


. This would allow the painter to complete the painting of the wall and baseboard trim of corner


1


B.





FIG. 3

illustrates shield


10


being used for painting an outside corner


40


of a wall. In this illustration, the painter would likely grasp major portion


12


, perhaps along straight edge


34


, and force right-hand outside corner shield


42


against corner


40


. The other corner


44


illustrated in

FIG. 3

could then be painted simply by rotating paint shield


10


generally ninety degrees such that corner


44


is received within outside corner shield


42


.




Because of the design of the paint shield


10


of the present invention, and its lightweight and flexible nature, it can be grasped in numerous positions and resiliently deformed in order to meet a number of shielding needs.




Paint shield


10


is relatively large. As noted above, edge


34


is, in one preferred embodiment, approximately thirty-six inches (36″) long. Edges


30


and


48


are approximately ten inches (10″), and the sides


50


,


52


and end


54


of secondary portion


14


are also approximately ten inches (10″), with secondary portion


14


preferably being centered along major portion


12


, as shown in FIG.


5


. However, because of the flexibility of shield


10


, the effective length of the sides is variable in that one or more of the ends of an edge can be bent up (or down) to shorten, and thus reduce, the effective length of the sides as necessary.




Because of the sheer size of paint shield


10


, it provides sufficient surface area for use in spray painting operations where there will tend to be more splatter and over spray, and thus more risk of paint being found on surfaces or objects which should not receive paint, as compared to application of paint with a brush. It is to be understood, however, that paint shield


10


could also be used in applications where paint is being applied by brush. However, it paint shield


10


is to be used solely as a shield for painting by brush, the size of the shield may be varied, and perhaps made smaller, if desired. It is also to be understood that the dimensions of paint shield


10


set forth herein are for example purpose only, and paint shield


10


could be made in variety of other configurations. For example, although not shown, paint shield


10


could be made in a generally L-shape, instead of the T-shape version as shown in the drawings. Furthermore, although not shown, paint shield


10


could be formed as simply a straight member. For example, secondary portion


14


could be removed altogether from major portion


12


, thereby leaving only major portion


12


as a paint shield.




In addition to outside corner shields


28


,


42


, shield


10


includes six inside corner shields


31


,


33


,


35


,


37


,


39


and


41


which allow for shield


10


to be positioned in a number of orientations as needed for painting inside corners.




An advantage of paint shield


10


is that it is easily washable, and if, for example, latex paint is being used, can be readily washed with water and then immediately put back in service. Paint shield


10


is also versatile in that it can be used for painting walls, floors, cabinets, trim, and in numerous other painting applications.




Because of the lightweight and low profile nature of paint shield


10


, the painter can easily flip shield


10


one way or the other to provide the proper shielding needed by the painter. If the painter is painting a corner, as discussed above with regard to

FIG. 3

, and then needed to paint another corner, shield


10


could simply be slid and/or rotated to the next corner without being flipped over. This is important since the shield


10


may have paint on the upper surface, and this allows shield


10


to continue to be used without having to first clean shield


10


in order to accommodate the next corner.




In operation, paint shield


10


would be used to paint a surface by using one or more of the edges


30


,


34


,


48


,


49


,


50


,


52


,


53


,


54


which would be placed against the surface and paint then applied by brushing or preferably by spraying upon that portion of the surface adjacent the edge or edges. If an inside corner, such as shown in

FIG. 4

, is to be painted, one of the inside corner shields


31


,


33


,


35


,


37


,


39


,


41


would be inserted into the corner and paint applied. If there was insufficient wall space to lay shield


10


flat in order to paint such inside corner, due, for example, to corner


18


′ in

FIG. 4

, then shield


10


could be depressed firmly along a mid-portion into the corner such that paint may be applied as close to the corner as possible. Then, shield


10


would be removed and rotated such that an edge could then be inserted into the corner, and painting of the corner completed.




If an outside corner is to be painted, such as shown in

FIG. 3

, one of the outside corner shields would simply be placed against such corner and paint then applied.




Paint shield


10


finds particular application in repainting, or recoating, applications, such as when apartments are repainted between tenants. In such a situation, shield


10


can first be used for applying a paint to the trim surfaces, such as a gloss or semi-gloss paint, wherein the floor surface would be shielded from paint. Then, in painting the wall surfaces above the trim, shield


10


would be used to shield the trim from the wall paint, which could be flat, or have different gloss characteristics than the trim, and/or which could be of a different color than the trim.




Another feature of shield


10


is that because of its flexible, planar shape, it is easy to transport and store. It can be rolled up or it can be bent in order to fit into a storage position for transport, as necessary. Because of the material preferably used for constructing shield


10


, namely HDPE, shield


10


is non-marring and non-scarring, which reduces the likelihood of damage to surfaces during painting. Further, because of the thin profile of shield


10


, it can also easily be slid under doors, or into other crevices, as necessary, for shielding during painting. Additionally, the smooth, generally slick surface of shield


10


allows the shield to easily slide along a floor or wall during painting, with minimal frictional resistance.




Accordingly, the present invention provides a paint shield which is lightweight and relatively simply to manufacture, and which is durable and easy to use.




While preferred embodiments of the invention have been described using specific terms, such description is for present illustrative purposes only, and it is to be understood that changes and variations to such embodiments, including but not limited to the substitution of equivalent features or parts, and the reversal of various features thereof, may be practiced by those of ordinary skill in the art without departing from the spirit or scope of the present disclosure.
