1. Field of the Invention
The present invention relates to a method and apparatus for shielding paint from being sprayed onto a roof structure of a building or home and, specifically, a paint shield configured to be temporarily self-retained to the roof structure to shield overspray from the roof structure while painting a side wall of the building or home.
2. State of the Art
When painting, it is obviously desirable that surfaces which should not receive paint, do not receive paint. For this reason, various paint shields have been developed over the years. Typical paint shields can include various hand-held devices with rigid straight edges, masking tape and even paper with an adhesive edge. Many of the paint shields on the market today are for indoor use for painting the interior walls, molding and ceiling of a home or building. When painting large surface areas, paint sprayers are often employed. Paint sprayers may be more efficient; however, painting with a sprayer often leads to spraying undesired surfaces. To overcome this problem, there are large paint shields with long handles available. However, these long-handled paint shields must be held by a painter in one hand while holding the paint sprayer in the other hand. This arrangement of manually holding the shield while painting is tiresome and cumbersome, resulting in fatigue and unavoidably leading to mistakes, discontinuities in the painted surface (due to undesired movement of the shield while painting) and accidental overspray to undesired surfaces not meant to be painted. Further, the accidental overspray problem becomes perpetuated due to the limited shield width of the long-handled paint shields.
Painters are often contracted to paint the exterior surfaces of homes. Exterior surfaces are usually very large surfaces and, as such, painters typically use paint sprayers to increase their efficiency. Typical to most exterior surfaces, the side walls are the desired painting surface and the roof structure is the undesired surface for receiving paint. Painters often employ the same long-handled paint shields used for interior use for exterior use to prevent over-spray from getting on the roof structure. Although a long-handled paint shield can assist in preventing over-spray from getting on the roof structure, the above-identified problem relating to manually holding a long-handled paint shield while painting is perpetuated due to the large surface areas at the exterior of the home.
Accordingly, there exists a need for a paint shield made specifically for exterior surfaces that allows the painter the efficiency desired by employing a paint sprayer while also limiting the painter's fatigue by limiting the necessary tools the painter must handle while painting. There also exists a need for a paint shield that shields large areas or entire side walls at a time, thereby limiting the potential of mistakes and overspray to undesired surfaces.
In view of the shortcomings in the art, it would be advantageous to provide a paint shield that temporarily attaches to a roof structure of a home to shield the roof structure while spray painting side walls of the home.
Accordingly, the present invention relates to a self-retained paint shield for shielding an exterior roof structure while spray painting exterior side walls of a home or building. The paint shield includes a shield portion and an exterior-roof attachment portion. The shield portion is configured to shield at least a portion of the roof structure from paint spray. The exterior-roof attachment portion is connected to the shield portion and includes two upwardly extending attachment side walls extending at a lower end from each other. With this arrangement, the exterior-roof attachment portion is configured to attach to the end of the roof structure in a self-retained manner while the shield portion shields at least a portion of the roof structure from paint spray.
In another embodiment of the present invention, the paint shield can include a primary paint shield and an elongated roof-attachment element. The elongated element includes a longitudinal length having a cross-section with a W-shaped configuration extending substantially along the longitudinal length thereof. Further, the elongated element can include a roof attachment portion and a shield attachment portion. The roof attachment portion is configured to attach to an end of a roof structure so that the elongated element is self-retained to the roof structure. The shield attachment portion can be connected to the roof attachment portion and includes a shield portion configured to shield paint spray. Further, the shield attachment portion is configured to receive and removably retain the primary shield in a self-retained manner.
In another embodiment of the present invention, the paint shield includes an elongated roof-attachment element. The elongated element includes a longitudinal length having a cross-section with a J-shaped configuration extending substantially along the longitudinal length thereof. Further, the elongated element can include a roof attachment portion and a shield portion. The roof attachment portion is configured to attach to an end of a roof structure so that the elongated element is self-retained to the roof structure. The shield portion is interconnected with the roof attachment portion and is configured to extend upward above the roof attachment portion to shield the roof structure from paint spray.
In one embodiment, the present invention provides that the roof attachment portion of the elongated element, or the paint shield, can be removably retained to a drip edge of the roof structure with an interference type fit.
Other features and advantages of the present invention will become apparent to those of ordinary skill in the art through consideration of the ensuing description, the accompanying drawings, and the appended claims.

Reference will now be made to the exemplary embodiments illustrated in the drawings, and specific language will be used herein to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Alterations and further modifications of the inventive features illustrated herein, and additional applications of the principles of the inventions as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.
Referring to
In one embodiment, the paint shield 100 includes an elongated element 110 and a primary shield 150. The elongated element can include a substantially W-shaped cross-section configured to attach and be self-held or self-retained to the drip edge 20 of a pitched roof of the home. Such elongated element 110 is also configured to receive the primary shield 150 in a self-retained manner. With this arrangement, the elongated element 100 and the primary shield 150 both substantially prevent and shield the roof structure 15 and the drip edge 20 from receiving undesired paint spray 30 while a person manually sprays the side wall 25 or painting surface of the home 10. Furthermore, the W-shaped configuration can provide an interference type fit for retaining the elongated element 110 to the drip edge 20 as well as retaining the primary shield 150 to the elongated element, thereby, allowing for easy removal and placement thereof.
The drip attachment portion 120 is defined by a back portion 122 and a first intermediate portion 126. The back portion 122 extends upwardly from the first lower bend 112 to a back free end 124. The first intermediate portion 126 extends upwardly from the first lower bend 112 to the upper middle bend 116. As such, the back portion 122 and first intermediate portion 126 extend upwardly from the first lower bend 112 to define a first pocket 128. The first pocket 128 is sized and configured to receive and retain the drip edge 20 to allow the elongated element 110 to be self-retained to the drip edge 20.
As previously indicated, the drip attachment portion 120 can be self-retained to the drip edge 20 with an interference type fit (drip edge 20 shown in outline), allowing for easy positioning, removal and retention of the elongated element 110 to the drip edge 20. The interference type fit is employed due to the first pocket 128 narrowing as a function of depth as defined by the back portion 122 and the first intermediate portion converging at the first lower bend 112. With this arrangement, as the first pocket receives the drip edge and is forced therein, the back portion 122 and the first intermediate portion 126 resist separation (shown by arrows 156), thereby, providing a spring-like effect or interference type fit to temporarily retain the elongated element 110 to the drip edge 20. The resistive strength or spring strength of the drip attachment portion 120 can be modified via various factors, such as, but not limited to, length of the back portion 122 and first intermediate portion 126, material type employed for the elongated element 110, thickness of the elongated element 110 and drip edge 20, etc., as known by one of ordinary skill in the art. Further, it should be noted that alternate or additional attachment means for the drip attachment portion 120 can be employed, such as utilizing clips, hangers, clamps, adhesive, magnetic means or any other suitable temporary attachment means, or any other structure suitable for providing an interference type fit, known in the art.
The shield attachment portion 130 is defined by a shield portion 132 and a second intermediate portion 136. The shield portion 132 extends upwardly from the second lower bend 114 to a shield free end 134 whereas the second intermediate portion 136 extends upwardly from the second lower bend 114 to the upper middle bend 116. Similar to the drip attachment portion 120, the shield portion 132 and the second intermediate portion 136 extend upwardly from the second lower bend 114 to define a second pocket 138 for receiving and retaining the primary shield 150 to be self-retained therein with an interference type fit. As such, the shield attachment portion 130 is sized and configured to provide the necessary spring-like component to retain and readily remove the primary shield 150 to and from the shield attachment portion 130. Further, other or additional attachment means of the primary shield 150 to the shield attachment portion 130 may be employed, such as by utilizing clips, hangers, clamps, adhesive, magnetic means or any other suitable temporary attachment means known in the art. Further, the shield attachment portion 130 may include alternate structure than that disclosed that provides an interference type fit for the primary shield to be retained to the elongated element 110.
The W-shaped configuration of the elongated element 110 can be a modified into various shapes, additional lengths and bends. Further, such elongated element 110 can be made from thinly formed resilient material, such as sheet metal, formed from any known resilient material such as steel, aluminum, tin, etc. or polymer type materials, or any other types of materials providing a resilient effect to allow the elongated element 110 to resiliently self-hold to the drip edge 20 as well as resiliently hold the primary shield 150. As known by one of ordinary skill in the relevant art, the elongated element 110 can be readily made from, for example, sheet metal and bent at appropriate positions to form the desired W-shaped configuration.
The primary shield 150 can be made from card-board, or any other suitable material, such as plastic, aluminum or sheet metal. The primary shield 150 can be sized and configured with an elongated length that is slightly longer than the length 104 (
In this embodiment, the elongated element 210 can be made with similar materials, lengths, heights, etc. as that disclosed for the elongated element in the previous embodiment. Since the shield portion 250 in this embodiment can be made as a unitary structure with the drip attachment portion 220, it should be noted that the shield portion 250 can extend to any suitable height, such as six inches to twenty-four inches and, preferably, between about eight to sixteen inches.
Further, as will be readily apparent to one of ordinary skill in the art, the present invention is not limited to one or two lower bends within the elongated element. For example, there may be additional bends within the elongated element in order to gain the clearance necessary to bypass an end of the pitched roof structure. Some examples of such additional bends are disclosed in the following embodiments illustrated in
