Description
FIELD OF THE INVENTION

The present invention relates generally to the field of fluid applicators. More specifically, the present invention relates to an adjustable and swivelable paint roller frame that can be used with roller covers of various sizes. More specifically, the adjustable paint roller frame is a portable device that enables operators to reach elevated areas, narrow areas and hard to reach areas. The frame includes a handle, an adjustable swivel, and a head section. The head section receives and accommodates roller covers and the handle is configured to be pivotally movable 90-degrees left and right, relative to the substantial midpoint of the head section enabling a smooth and consistent paint application. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices, and methods of manufacture.


BACKGROUND

By way of background, application of paints and coatings require a paint roller. A paint roller is a paint application tool used for painting flat surfaces rapidly and efficiently. The paint roller uses a roller cover that absorbs paint and transfers it to a painted surface. The roller cover is secured to a head section that is often attached to a handle. In conventional rollers, the roller cover is simply pushed onto the frame or head. Thus, the fit is tight, making it difficult to get the roller cover off the frame after painting. Operators may be reluctant to remove the roller cover after painting, and thus the roller cover is saturated with paint, makes a mess, and ultimately paint that could have been applied to a surface is wasted. Individuals desire paint rollers that allow users to remove and attach roller covers easily.


Further, conventional rollers do not accommodate roller covers of multiple sizes, and thus require individuals to carry multiple frames for different types of roller covers. This is expensive, uncomfortable for operators and consumes unnecessary storage space.


Even with expensive rollers, operators find it difficult to paint elevated areas, narrow areas, and other hard-to-reach areas. Heretofore known paint devices comprise a handle and head section that generally remain fixed relative to each other, wherein the handle remains perpendicular to the head section or the roller cover, and therefore do not allow painting in different orientations and painting angles.


Therefore, there exists a long felt need in the art for an improved paint roller frame that facilitates easy removal of a roller cover. There is also a long felt need in the art for an improved paint roller frame that can accommodate roller covers of various sizes. Additionally, there is a long felt need in the art for an improved paint roller frame that can enable users to reach and paint hard-to-reach areas and elevated areas. Moreover, there is a long felt need in the art for an improved paint roller frame that enables individuals to paint in different painting angles. Further, there is a long felt need in the art for an improved paint roller frame that is easy to store and use. Furthermore, there is a long felt need in the art for an improved paint roller frame that maintains an easy-on and easy-off installation of the paint roller cover. Finally, there is a long felt need in the art for an improved paint roller frame that prevents excessive mess and wastage of paint, and improves overall workflow when painting any type of surface.


The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a telescoping and adjustable fluid applicator device. The fluid applicator device enables users to securely attach or remove a paint roller cover and enables the cover to rotate generally from about 90-degrees left to about 90-degrees right. The device features a head section including a telescopic top edge that has a pair of opposing ends wherein each end has a connector for accommodating the roller cover. The length of the telescopic top edge can be adjusted to accommodate various sizes of roller covers. The device also includes a telescopic handle having a top end and an opposite projection end, a plurality of locking tabs is positioned at the projection end. An adjustable swivel is attached to a mounting assembly, wherein the mounting assembly is removably-attached to the head section, and the handle and the head section are pivotally-coupled using the adjustable swivel enabling ninety-degree rotation of the handle relative to the perpendicular direction of the head section. This enables users to maintain smooth and consistent paint application, thereby improving overall workflow when painting.


In this manner, the pivotable and telescoping paint roller frame of the present invention accomplishes all of the forgoing objectives and provides a modified paint roller frame with a multipurpose adjustable swivel. The head section can accommodate roller covers of multiple sizes and an operator can reach elevated and hard-to-reach areas. The connectors allow easy-on and easy-off installation of the paint roller cover from the head section. The adjustable swivel enables users to rotate the roller cover 90-degrees left and right to maintain smooth, consistent paint application.
