Angle-rite adjustable paint roller

by Lowrey, Roland E.; Guest, James M.;



BACKGROUND OF THE INVENTION

1. Field of the Invention

This application pertains to an angularly adjustable paint roller for the application of paint or other coating materials to a surface for the expressed purpose of protecting, decorating and the like.

2. Description of Prior Art

Commercially available paint rollers consist of a one-piece angular roller frame shaft which connects a handle at one end and a roller cover horizontal to the handle at the other end. The roller frame shaft, cover and handle comprise a standard one piece paint roller that is non adjustable. Difficulty is often experienced when trying to apply coating materials to angular surfaces or where obstacles are present using this standard art device. Various attempts have been made over the past several years to modify the construction of the fixed paint roller frame to make it adjustable so as to make it easier to paint angled surfaces, such as exterior facia boards, gabled roofs, dormers, over and around door casings, windows, ceilings, and multi-angled vaulted ceilings to paint behind furniture or other areas not accessible, all without the need of body elevation aids such as ladders and scaffolding.

None of the previously adjustable paint rollers or art device modifications have satisfactorily solved these painting challenges. The basic problem with these prior art devices is that they have to be set and held at a fixed predetermined angle which can only be changed by loosening, moving and retightening the adjustment mechanism components. The prior art pivotal devices also have a tendency to loosen while applying the coating material. Additionally, the roller itself can only be held securely or flat against the mating surface at a minimal angular distance from the person applying the coating material. The designs of the prior art devices also make them expensive to manufacture compared to the standard non-adjustable roller frames. Most importantly, none of the prior art devices are capable of being adjusted while in motion during the application process whether it be to a horizontal, vertical or transaxial surface.

SUMMARY OF THE INVENTION

The above noted disadvantages are overcome by the preferred embodiments of this new paint roller frame which has its pivotal adjustment at the first bend in the shaft just above the handle. The adjustment mechanism is designed to hold the handle shaft portion and the U shaped shaft portion at any desired angular position. The mechanism is capable of allowing the position to be changed by the person applying the coating material by exerting pressure on the handle shaft portion while the roller cover is against the mating surface and then moving the handle shaft portion to the new desired angular position. The position of these two (2) portions can also be changed by moving one of the two (2) shaft portions by hand. The tension on the pivotal components comprising this adjustment mechanism is preset so as to hold it firmly in-placed without loosening during application of the coating material yet the tension can be overcome allowing angular movement through the exertion of pressure as just described. The use of a threaded stud, steel washer, nylon washers and a locknut give this adjustment mechanism this noted capability.

The uniqueness of this design circumvents the need to loosen, retighten, disassemble and reassemble the pivotal adjustment components in order to change or reset the roller cover to a new angle of choice. The pivotal design allows the roller cover to be positioned at any angle within the rotation circumference even perpendicular to either side of the handle. This provides maximum angular flexibility not found in prior are devices.

The components comprising this adjustment mechanism are standard off-the-shelf parts. The reconfiguration of the paint roller into two (2) portions makes it simple to manufacture.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

Referring now to the drawings, and firstly to FIG. 1, the invention is shown generally at numerals 2, 3, 5, 6, and 7. These are the preferred materials for use in the adjustment mechanism. When installed with numerals (4) and (9) and (8) and (1), they comprise the new art device.

As shown in FIG. 1 and FIG. 2, the adjustment mechanism includes a threaded stud (2) that is installed through a hole that is drilled or punched in the flattened end of the handle shaft (1). The hole is large enough to allow penetration of the stud (2). A nylon washer (3) is then placed over the protruding portion of the stud (2). Next, the U shaped shaft (4), with the hole in the center of the flattened end, is placed over the protruding portion of the stud. A nylon washer (5) and a steel washer (6) are placed over the remaining portion of the protruding stud (2) which is then capped by a locknut (7) securing all components together. The locknut (7) is tightened so as to put friction on the pivotal adjustment pieces and both shaft members portions (1) and (4). This tension holds the angular position of the roller in-place for the coating material application process. The nylon washers permit movement of the shaft members portions so that the angle of choice can be easily reset. This is accomplished by applying pressure on the roller handle (8) while the roller cover (9) is pressed against the surface to be painted and then moving the roller handle (8) to either side to obtain the desired angle of choice. This same action can be accomplished while moving the roller cover (9) over a surface thereby making the roller adjustable while in motion or use. Adjustment can also be made by manipulating the shaft member portions by hand.

The orientation of the roller shaft (4) and roller cover (9) can be articulated back and forth to any desired angle as shown in FIG. 3. Thus, the roller cover (9) can be adjusted to any angular position up to being perpendicular to either side of the roller handle and handle shaft portion.

The locknut (7) can be tightened or loosened to obtain any desired tension by the user. Once a particular tension is chosen, the locknut (7) will not loosen at that friction tightness even after repeated pivoting of the shaft member portions. The adjustment mechanism will not clog with coating material or lock up.

FIG. 4, which is comprised of FIGS. 4a, 4b, 4c and 4d, shows four (4) of the various angles at which the roller cover (9) can be positioned and used with or without the depicted extension pole. The applicator is able to reach and paint many of these higher areas, without the use of ladders or scaffolding or other type body elevation aids, by installing an extension pole to the roller handle (8). The extension pole and the adjustable features of this paint device allow the applicator to more easily reach various heights from floor level, to get into potential inaccessible areas, or to paint behind obstacles that have minimal accessibility. These tasks are made even easier because the roller assembly angularity can be adjusted while the roller cover (9) is being moved across the surface.

The invention shown and described herein reflects the most practical and preferred embodiments. It is recognized that departures may be made from within the scope of the invention, which is, therefore, not to be limited to the details disclosed herein, but is to be afforded the full scope of the claims so as to embrace any and all equivalent apparatuses and articles.
