Description

Filling Material Finishing Tool {FILLER MATERIAL FINISHING TOOL}

FIELD OF THE INVENTION The present invention relates to portable devices used to flatten and refine filling materials.

Household goods and paint shops typically supply consumers with filling materials to improve the appearance of their work. Such filling materials are used for door trims, windows, baseboards, bathtubs, showers, sinks, wall scratches, corners and other areas that require a professional finish appearance and / or sealing. Filling materials were originally applied using fingers, rods, spoons and the like originally. The inventors then developed several types of devices to accomplish the task. Some devices are used with caulking guns. Other devices are portable but have several limitations. Effective tools for flattening and smoothing the filling material are useful to accommodate various angles and irregular surfaces of the intersection and to give a professional appearance.

For example, various devices have been proposed by Ray, such as US Pat. No. 6,305,926B1, issued October 21, 2001. Ray's device must be placed on the finger to flatten the filling material, so care must be taken not to touch other areas where it is not good to place the filling material, or the device can be removed from the finger and placed back on the finger when it needs to be used again. You have to. U.S. Patent No. 6,219,878 and Marchbanks, issued April 24, 2001 by Dewberry, require excessive caulking to be applied for the tool to function properly. Both tools are designed to collect excessive caulking, resulting in waste and the need to clean and remove excess caulking from the tool. U.S. Patent No. 5,792,489, issued August 11, 1998, by Liberman, is expensive to manufacture with excessive parts and difficult to clean. US Patent No. 5,675,860, issued October 14, 1997 to Campbell, is limited in flexibility because only a rim margin is formed of a flexible, elastomeric material around the handle. An obtuse or acute joint is difficult to apply fill material.

Thus, some purposes and advantages of the present invention are:

a) providing tools to straighten, flatten and trim the filling material to achieve a professional finish;

b) providing tools to level and trim the fill material into acute, oblique and vertical joints;

c) provide a tool with flexibility that makes it possible to match surface variations;

d) provide a tool that can be used without a handle for use in a limited work area;

(e) To provide a tool with a minimum of parts.

Another object and advantage is to provide a filling material finishing tool that can be used easily, conveniently and reliably by both skilled and novice "handcrafters".

According to the present invention, the filling material finishing tool consists of an elongated triangular shaped elastomeric material with or without a handle to smooth and smooth the filling material.

It is also to provide an elongated triangular shaped elastomeric portion that flattens and trims the fill material as it is drawn over the fill material, and instructions that the portion can flatten and trim the fill material when drawn over the fill material. By providing a method of selling a device for leveling and trimming the filling material is contemplated.

In another embodiment of the present invention, a coke applicator having an elongated triangular shaped elastomeric portion that flattens and trims the fill material when drawn over the fill material is contemplated, and the applicator is filled when the part is drawn over the fill material. Include instructions that the material can be flattened and trimmed.

1, 7, 8 and 9-preferred embodiments

Preferred embodiments of the filler material finishing tool of the present invention are shown in FIGS. 1 (perspective view in use), 7A (perspective front elevation), 7B (perspective back elevation), 8 (side view) and 9 (front view). As can be seen in the figure, the filling material finishing tool 20 comprises an elongated triangle of predetermined length, formed of an elastomeric material. The elastomeric material may vary from very flat to rigid to allow the filler material finishing tool 20 to conform to the viscosity of the filler material used. In a preferred embodiment, the filling material finishing tool 20 is formed of silicon. However, the fill material finishing tool 20 may be comprised of various elastomeric materials, such as rubber, vinyl, foam, and the like. It may be produced by extrusion and cut or extruded to a predetermined length.

The front portion 50 (FIGS. 7A and 8) is usually inclined at an acute angle 68 with a peak 71 (FIG. 8). In FIG. 11A, the side walls 56 and 58 combine to form a concave side wall convex portion 80. Top portion 54 intersects side portions 56 and 58 at obtuse angles 72 and 73. As shown in FIG. 9, the side portions 56, 58 normally intersect, forming an oblique angle 70 at the vertex 71. Top, side walls typically intersect, forming acute angles 72, 73. 11A shows side portions 56 and 58 that combine to form rounded convex intersections 80 to flatten the fill material in a concave shape. The back wall 52 (FIG. 7B) typically intersects the top 54, sidewalls 56, 58 (FIG. 9) at approximately right angles at the edges 62, 65 and 66. FIG. The front portion 50, the top wall 54, and the intersection portion 60 (FIGS. 7A, 8) generally form an obtuse angle 61 (FIG. 8).

2, 3, 4, 5, 6, 7A, 10B, 10C-Additional embodiments

Additional embodiments in which the handle 30 is attached to the filling material finishing tool 20 are shown in FIGS. 2, 3, 4, 5, 6, 10A and 10B.

10B, 10C-Alternative Embodiment

There are various possibilities for the shape formed by the intersection of the outer surface forming the edge of the filling material finishing tool 20. The outer edges of the tool 20 formed by the intersections of the walls 50, 52, 54, 56 and 58 can be shaped into a number of configurations including sharp, inclined, recessed and convex. 11B shows the sides 56, 58 that combine to form a flat sidewall intersection 82 to flatten the fill material in a flat form. 11C shows the sides 56 and 58 that combine to form concave sidewall intersections 84 to enable the formation of convex portions of the fill material.

Operation-Figs 1, 2, 3, 4, 5, 6

Filling material 40 is typically applied to the joint formed by the vertical intersections of the two planes, and the tool 20 (FIG. 1) is drawn by hand drawing along the joint while flattening and trimming the filling material 44. Caught As the tool is drawn over the fill material 44, the vertices 71 (FIG. 9) disperse the fill material outwards, and the sides 56, 58 smooth and smooth it out.

The handleless filling material finishing tool 20 shown in FIG. 1 is well suited for use in limited work spaces.

2 shows the tool 20 in use with the handle 30 attached. The handle 30 provides the user with improved ease of use and control of the tool 20.

In FIG. 3, the tool 20 appears to be inserted at the joint of the plane 92 and the skirt 93, illustrating the ability of the elastomeric properties of the tool to conform to the irregular surface 90.

As shown in FIG. 4, the elastic properties of the tool 20 enable the tool to coincide with the oblique angle of the intersection 102 between the two planes 94, 95.

As shown in FIG. 5, the elastomeric properties of the tool 20 enable the tool to coincide with the acute angle of the intersection 104 between the two planes 96, 97.

In FIG. 6, the tool 20 is shown with the edge 63 (FIG. 9) inserted into a small acute angle 106 (FIG. 6) of the intersection between the two planes 98, 99 (FIG. 6). Both edges 63 and 64 can be used to apply filling material from opposite directions in a limited working space.

Advantages

From the above description, numerous advantages of the present filling material finishing tool become apparent:

(a) The filling material finishing tool can be used without a handle to apply the filling material in a limited space.

(b) The filling material finishing tool can be used with the handle when space permitting providing good control of the tool.

(c) This filling material finishing tool, composed of elastomer material, provides the ability of the “handcrafter” to obtain a flattened and trimmed filling material with professional results.

(d) The elastomeric composition of the filling material finishing tool enables the user to apply filling material to vertical and irregular joint surfaces, such as skirting and wall joints, obtuse joints, acute joints and small acute joints.

Conclusion, Segmentation, and Scope

Thus, the reader will understand that the filler material finishing tool of the present invention can be used to easily and conveniently apply filler material with professional results. In addition, the filling material finishing tool has additional advantages in the following aspects:

Providing for flattening and trimming the filling material;

Providing a tool for applying fill material to joints formed to have various crossing angles;

Provide tools for applying fill material in open and limited work spaces.

Although the foregoing description may have specific examples, these should not be considered as limiting the scope of the present invention, but as merely providing examples of some presently preferred embodiments of the present invention. Many other variations are possible. For example, the back side of the filling material finishing tool may intersect the top side and the side at an angle other than the vertical angle; The front part can meet the vertex at an obtuse angle; Sides, tops, fronts, and backs may be formed by curved surfaces or the like. However, it is not intended to limit the invention to the specific forms disclosed. In contrast, the intention is to cover all modifications, equivalents, and alternative arrangements falling within the spirit and scope of the invention. Therefore, the scope of the present invention should be determined not by the examples given, but by the appended claims and their legal equivalents.
