Description
Background of the Invention
1. Field of the Invention
The present invention generally relates to painting implements and, more particularly, is concerned with an attachment pad for use with paint roller assemblies for smoothing or otherwise treating the paint film being applied by the roller and for trimming or "cutting in" along surfaces adjacent to the surface being painted.
2. Description of the Prior Art
Rollers of many designs are commonly used applicators of paint and the like to surfaces. Although paint rollers are capable of superior results, the quality of application and texture of the applied paint is largely dictated by factors such as the type of roller, the properties of the paint, and the physical characteristics of the surface being painted. Known paint brush constructions have been deficient in providing an accessory or cooperating element that is capable of being affixed to the paint roller assembly for improving the quality or modifying the appearance of the film being applied.
The inherent configuration of a paint roller also causes difficulty in painting or trimming corners at the intersection of a surface adjacent the surface being painted, such as along a ceiling, door frame, and the like. As a result, it is often necessary to trim corners of intersecting surfaces by using brushes or other separate devices.
Consequently, a need exists for improvements in painting of surfaces with rollers by which the applied paint can be further enhanced through smoothing or other treatment during the painting operation. A need further exists for improvements in the trimming of intersecting surfaces while using a paint roller assembly.
Summary of the Invention
It is an objective of the invention to provide a unitary pad attachment for a paint roller assembly to provide a paint trimming an surface treatment capability to the paint film being applied. The attachment pad device of the invention is directly affixed to the roller assembly in a manner that a material, such as a fabric or foam face contacts the applied paint film for smoothing or creating some other aesthetic affect. In addition, the attachable pad device herein disclosed is capable of a trimming or "cutting in" operation at the corners of intersecting surfaces during use of the roller. The foregoing enhancement of the paint surface and trimming capability of the invention are attained by an inexpensive device that is lightweight and does not interfere onto the expected ease of loading paint with a roller.

Description of the Preferred Embodiments
Referring now to FIG. 1, there is illustrated a first embodiment of the pad attachment device of the invention shown affixed to an existing paint roller assembly and generally designated by reference numeral 2. The known paint roller assembly includes a paint roller 4 having a circumferentially arranged fabric or fiber material 4' that absorbs paint and applies a film to the surface being painted. In the assembly shown in FIG. 1, the roller 4 is rotatably mounted by means (not shown) to a paint shield housing 6 also of a known configuration. The housing 6 may include a handle for manipulation of the roller assembly in use and end walls (not shown). Although the invention is shown in conjunction with a paint shield housing, the invention may also be attached to other paint roller assemblies by suitable techniques (not shown).
The pad attachment device 2 is mounted on an enlarged lip 8 of housing 6 and extends in substantially parallel relationship to the axis of rotation of the roller 4. The pad attachment device 2 includes a single piece, pad holder 10, which may be molded or otherwise formed from a plastic material. Pad holder 10 is arranged to snap into fixed position substantially over the length of the enlarged lip 8 of the paint shield housing 6. As seen in FIGS. 1 and 3, the pad holder 10 includes a retention pocket 11 formed by a somewhat curved inner housing wall 12, an integral end surface 14, and an outer section 16 disposed on the surface of lip 8 as seen in FIG. 1. The outer portion 16 is formed with a recess 18 having an approximate shape corresponding to the outer enlarged face of lip 8. The enlarged lip 8 may be positioned into the pocket 11 of pad holder 10 with recess 18 snapping into retention on the lip 8.
As further seen in FIG. 1, a portion 20 of the pad holder 10 angularly diverges outward from the outer surface of the housing 6 and terminates with a protuberance 22. A wall 24 projects outward from protuberance 22 and housing 6, and terminates with an outer edge portion 26 that retains the outer edge of a pad 30. The wall 24 may have a series of strengthening slots 24 as best shown in FIG. 3. As seen in FIG. 1, the pad includes a painting face 32 formed from a suitable material, such as a fabric, foam and the like, that is adhesively bonded to a rigid or semi-rigid backing member 34 by any known technique. The pad 30 is affixed to the holder 10 by retention in a pair of opposed open-ended slots 36,38 respectively formed on outer edge portion 26 and outer section 16 as seen in FIG. 1. The pad 30 may be replaced or mounted in position by being slid lengthwise in the open ended slots 36,38 or preferably, in the embodiment of FIG. 1, the holder 10 is hollow in enclosed area 40.
The holder 10 and pad 30 are arranged to span approximately the length of the housing shield 6 adjacent the roller 4 to provide contact with the surface being painted. As should be apparent in the foregoing description, the painting face 32 trails the roller 4 as it applies paint to a surface and acts to smooth the film applied by the roller. The surface of face 32 is disposed in a plane that is approximately tangential to the interface between the roller 4 and the surface being painted. Although the fabric painting face 32 shown in FIGS. 1 and 2 acts to smooth a paint film, the configuration and texture of the face 32 can be modified to create other painting effects where desirable. While the pad at attachment device 2 is further shown as an attachable fixture to the paint roller housing 6 in FIG. 1, it is within the scope of the invention to mold or otherwise fabricate the housing 6 and pad attachment device 2 as a unitary body (not shown) with the pad 30 being insertable or removable in slots 36,38
In FIG. 2, the paint face 32 is shown having a trapezoid shape 50, with the largest side 52 being the farthest from the axis of rotation of the roller 4. The face 32 forms an extended outward dimension in vicinity of side 52.
Referring now to FIG. 4, there is another embodiment of the pad attachment of the invention generally designated as reference numeral 2a. The pad holder 10a is modified from the holder shown in preceding FIG. 1 and includes a solid molded configuration. The pocket 11a formed by portions 12a, 14a, and 16a snaps on the shield housing 6 in a similar manner as previously described. The pad 30a includes a fabric painting face 32a and a semi-rigid backing member 34a of any selected material. The backing member 34a includes opposed extended portions 60 that slide into the slots 36a and 38a formed in the bottom of body 10a. The slots 36a and 38a confront each other adjacent to a cutout area 62 of the holder 10a which receives the pad 30a.
Referring now to FIG. 5, there is illustrated still another embodiment of the pad attachment 2b of the invention. The pad holder 10b of pad attachment 2b has a slightly modified design than the holder 10a shown in FIG. 4. Specifically, the bottom face of the pad holder 10b is flat, while the slots 36b and 38b are formed on the lower outer sides of the pad holder 10b. The edge portions 70 of the semi-rigid backing material 34b are bent back in a modified U-shaped configuration so that the inner directed edges 72 engage the slot 36b, 38b. The pad 30b with face 32b may be slid into position lengthwise as in the previous embodiments.
Referring now to FIG. 6, there is illustrated another embodiment of the pad attachment device of the invention, generally designated by reference numeral 2c. The pad holder 10c of pad attachment device 2c is similar to the pad holders of the preceding embodiments, except that the slots for retention of the painting faces have been eliminated. In addition, paint face fabric 32c is directly affixed to the bottom 74 of the holder 10c by use of a suitable adhesive 76.
Referring now to FIG. 7, there is illustrated another technique for attaching the paint face to the holder. The holder 10d is the same general configuration as the holder 10c of embodiment of FIG. 6, but the painting face 30d comprises a flocked foam painting face 80 that is affixed to the face of the holder by an adhesive bond 82.
In the foregoing description of the embodiments of FIGS. 4-7, four alternative ways for attachment and forms of painting face have been described. Each of these techniques can be utilized in conjunction with the holder device 10 of FIG. 1, if desired.
Referring to FIG. 8, the holder 10e of the invention is shown formed with extended portion 90 along its outer face in parallel relationship to the axis of rotation of the roller (not shown). The extended portion 90 is intended to contact an adjacent wall 92 at edge 94 to space the remaining portions of holder 10e from the wall. In this position, the painting fabric face 32e projects outward when pressed against surface 96 to approach the intersection of the surfaces 92 and the painting surface 96 so that the face with retained paint can trim or cut in along a ceiling, door frame or other surface adjacent to the frame being painted. This offers an improved ability of a paint roller device to trim corners which is difficult with present designs. The extended portion 90 is offset from the face 32c to prevent paint from migrating to the edge 94 for unsatisfactory trimming results.
Referring now to FIG. 9, a modification of the trimming capability of the pad attachment device of the invention is shown. Although the holder of the facing can encompass any of the foregoing shapes, for purpose of illustration the pad holder 100 is shown with a flat configuration. A pair of wheels 102 are mounted in shafts 104 for rotation about axls extending perpendicular to the axis of rotation of roller 4. The wheels 102 permit the attachment device to be moved along wall 106 in parallel relation to the axis of rotation of the roller 4, such as during lifting the roller or otherwise traversing the surface 108 being painted for improved trimming results.
The foregoing detailed description has been given for clearness of understanding only and no unnecessary limitations should be understood therefrom as some modifications will be obvious to those skilled in the art.
