BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to trowels but more particularly a 3D (three dimensional) notch trowel for applying adhesive.

2. Description of Related Art

In construction and carpet and vinyl work, or similar it is common to use a trowel to apply a layer of adhesive onto a surface before affixing the flooring material. The process involves spreading a layer of adhesive material and creating grooves in the material using the notched edge of the trowel. The grooves help control the amount of adhesive material that remains on the surface.

Traditional 3D notch trowels are typically designed with square or V-shaped notches along the edge. The size and spacing of these notches determine the depth and width of the grooves in the adhesive, which in turn controls the thickness of the adhesive layer. However, these conventional trowel designs may not always provide a consistent thickness of the adhesive layer, leading to problems when the flooring material is installed.

Furthermore, conventional trowels may require significant manual adjustment and skill from the user to achieve a consistent adhesive. This can lead to inconsistent results, especially in the hands of less experienced users. These issues can result in longer work times, increased material waste, and lower quality final products.

Thus, there is a need for an improved 3D notch trowel that can reliably and consistently apply a controlled thickness of adhesive, regardless of the user's level of experience. It would be advantageous if such a tool could improve the efficiency of the flooring process, reduce material waste, and enhance the quality of the final flooring work. Consequently, a solution is provided.

DETAILED DESCRIPTION OF THE INVENTION

The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the general principles of the present invention have been defined herein to specifically provide an improved 3D notch trowel.

It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. The terms “a” or “an,” as used herein, are defined as to mean “at least one.” The term “plurality,” as used herein, is defined as two or more. The term “another,” as used herein, is defined as at least a second or more. The terms “including” and/or “having,” as used herein, are defined as comprising (i.e., open language). The term “providing” is defined herein in its broadest sense, e.g., bringing/coming into physical existence, making available, and/or supplying to someone or something, in whole or in multiple parts at once or over a period of time. These terms generally refer to a range of numbers that one of skill in the art would consider equivalent to the recited values (i.e., having the same function or result). In many instances these terms may include numbers that are rounded to the nearest significant figure. The term “flooring” may include any surface that an adhesive is intended to be applied to, e.g. floor, wall, or ceiling. The term “3D” represents an edge of the trowel having depth, and specially a greater depth than the depth of the blade.

FIG. 1 is a top view of the improved 3D notch trowel according to an embodiment of the present invention. Referring now to FIG. 1, the improved 3D notch trowel 100 is illustrated. In one embodiment, the trowel 100 comprises a blade 102, a first notched edge 104, a second notched edge 106, a pair of flat edges 108, a shank 116, and handle 118. For the purposes of this disclosure the first and second notched edges 104 and 106 define the inventive features of the invention. The other features of the invention are typical components found in notch trowels and their details are considered outside the scope of the present invention, however these components are necessary for use. The following provides a general description, but it should be understood that these components may vary as well known in the art. The handle 118 enables a user to grip the trowel 100 during use. It is shaped and designed to be ergonomic and comfortable for extended use. In some embodiments, the handle 118 is typically made of a durable and non-slip material such as plastic, leather, rubber, or wood. The shank 116 is configured to connect the handle 118 to the blade 102. The shape or curve of the shank 116 may vary, as is well known in the art. In one embodiment, the blade 102 is flat, and rectangular in shape and comprises the notched and flat edges. It should be understood that although the illustrated embodiment depicts a pair of adjacent notched edges and a pair of adjacent flat edges, the number and location of the edges may vary. Further, as previously discussed, the structure of the notched edges defines the inventive feature of the present invention, however the illustrated structure of the first notched edge 104 the second notched edge 106 is just an exemplary embodiment of one variation of the present invention. As is well known in the art, typical notched edges have a V-shape or square profile with no depth in relation to the blade, which may be referred to as a 2D profile. In some embodiments, a typical notch construction (2D profile) may be provided on the second notched edge 106 rather than the inventive notched edge.

Referring now to FIGS. 2A-4B, various detailed views of the trowel 100 are illustrated. In some embodiments, the first notched edge 104 comprises a top portion 112 and a bottom portion 110, with the top portion 112 forming an opening 114. The distance between the top portion 112 and the bottom portion 110 defines a depth 122. In one embodiment, the depth is approximately 2 mm. In some embodiments, the depth is between 1-2 mm. Yet in other embodiments, the depth is 2-15 mm. However, it is understood that the depth may vary depending on the desired consistency of the adhesive during use. Further, as best seen in FIG. 4B when viewing the trowel from the bottom surface 120, a distance 124 is provided. This distance, defined by the space between the edge of the top portion 112 and the edge of the bottom portion 110, creates an angle on the notched edge perimeter surface 126 (best seen in FIG. 2B). In some embodiments, the angle is approximately 45 degrees. However, it should be understood that the angle may vary.

Also now, referring to FIGS. 5-6, various views of the trowel at different degrees of orientation (100A and 100B) in relation to a flooring surface are illustrated. Advantageously, the inventive notched edge shape of the present invention serves to create consistent and evenly distributed grooves in the adhesive at various angles (degrees of orientation) in relation to the flooring surface, this is particularly due to the depth and angle provided by the notched edge. Further, the inventive notched edge enables the trowel to deliver a uniform thickness of adhesive material across the surface, contributing to improved adhesion and a higher quality of finished flooring work, especially when utilized by users of varying skill levels.

In the depicted embodiment of the invention, the notched edge of the trowel features a round shape, providing a specific depth, angle, and opening as illustrated. However, while the round represents one specific implementation of this inventive concept, it's essential to underscore that the shape of the grooves on the notched edge could take various forms. Simply put, the invention is not limited to a round profile. Referring now to FIGS. 7A-D, the 3D notched grooves could be shaped rectangular 104A (or square), triangular 105B, triangular with reduced spacing 105C (minimized bottom portion), circular or round 104D as previously discussed, among other shapes, as long as these shapes have the same characteristics as the illustrated shapes, specifically having an upper and lower portion defining a depth, angle, and opening. It should be noted that any of the various profile shapes may include a varied bottom portion width, such that the space between groove shapes may vary. FIG. 7E shows the profile from the side showing the approximate 45 degree angle of the perimeter surface.

Another advantage of the present invention is the extended life cycle of the trowel compared to traditional trowels of the prior art. As is well known in the field, frequent use of trowels can cause their edges to become uneven or damaged, affecting the spread of materials such as adhesive. Typically, this issue necessitates the user filing down the edge of the trowel with a rod file. However, due to the flat shape of a typical trowel edge, this process yields varying results and may result in the trowel having more uneven groove structures within its notches. After filing, the size of the grooves are reduced.

The present invention, with its angled perimeter edge on the notched side, allows a user to easily and more intuitively file down the angled edge to restore the profile of the notched edge using a flat file. Further, due to the unique profile and structure of the notched edge, the trowel of the present invention may be filed down more times than a typical trowel and still maintain the same consistency of material application. This is attributed to the fact that when filing a traditional trowel, its notches are reduced in size with each filing. Eventually, this reduction renders the trowel unusable. In contrast, the present invention's design ensures that its functional performance remains consistent, even with repeated filing, thus prolonging the usability of the trowel. In some embodiments, the 3D profile may extend to increase the life cycle of the trowel. Further, filing the 3D profile of the present invention ensures the notched edge is of the same specifications as originally provided, which can't be said for the trowels of the prior art.

The extended life cycle of the trowel proposed in this invention offers several significant benefits. First, it can lead to substantial cost savings for the user. By allowing for repeated filing and restoration of the trowel's edge, users can maintain the tool's functionality over a longer period, reducing the need for frequent replacements and the associated expenses. Second, this longevity contributes to time efficiency. Minimizing the time spent on sourcing and purchasing new trowels, users can maintain an uninterrupted workflow, enhancing overall productivity. Third, the design of this trowel is user-friendly and intuitive, making it an accessible tool for users of all skill levels. Lastly, the ability of this trowel to maintain a consistent application of material, even after multiple filings, underscores its versatility. This makes it a reliable and adaptable tool for a wide range of projects and conditions over time.
