Trowel

Abstract

The present invention is a trowel having a blade with a rounded side edge, a straight side edge, and a notched edge between the rounded side edge and the straight side edge. The trowel may include a handle disposed opposite the notched edge and substantially parallel to the straight side edge, aligned with the plane of the blade. The blade may be made of a thin or flexible material, allowing the blade to be slightly deformed during use to create a consistent layer of adhesive. The rounded edge may be of a relatively smaller radius, allowing for a wider, shorter blade. In other embodiments, the rounded edge may be of a relatively bigger radius, allowing for a narrower, taller blade. The notched edge may be square notches, v-notches, u-notches, or other notch shapes according to user preference.

DETAILED DESCRIPTION

(6) This invention relates generally to construction tools, and more specifically to tools for spreading and scraping adhesives.

(7) Specific details of certain embodiments of the invention are set forth in the following description and in FIGS. 1-4 to provide a thorough understanding of such embodiments. The present invention may have additional embodiments, may be practiced without one or more of the details described for any particular described embodiment, or may have any detail described for one particular embodiment practiced with any other detail described for another embodiment.

(8) Importantly, a grouping of inventive aspects in any particular embodiment within this detailed description, and/or a grouping of limitations in the claims presented herein, is not intended to be a limiting disclosure of those particular aspects and/or limitations to that particular embodiment and/or claim. The inventive entity presenting this disclosure fully intends that any disclosed aspect of any embodiment in the detailed description and/or any claim limitation ever presented relative to the instant disclosure and/or any continuing application claiming priority from the instant application (e.g. continuation, continuation-in-part, and/or divisional applications) may be practiced with any other disclosed aspect of any embodiment in the detailed description and/or any claim limitation. Claimed combinations which draw from different embodiments and/or originally-presented claims are fully within the possession of the inventive entity at the time the instant disclosure is being filed. Any future claim comprising any combination of limitations, each such limitation being herein disclosed and therefore having support in the original claims or in the specification as originally filed (or that of any continuing application claiming priority from the instant application), is possessed by the inventive entity at present irrespective of whether such combination is described in the instant specification because all such combinations are viewed by the inventive entity as currently operable without undue experimentation given the disclosure herein and therefore that any such future claim would not represent new matter.

(9) FIG. 1 is an isometric view of the trowel having a handle 1 coupled with the top of blade 5. The handle 1 may have a full or partial tang or shank, and preferred embodiments will have a full tang in order to provide the best control of the trowel. The handle 1 may be substantially parallel to straight side edge 2. This offers a particular advantage over many existing trowels, because it allows both left-handed and right-handed users to use the trowel for loading the trowel and spreading the adhesive, and because it allows for easy cleaning of the trowel by allowing a user to scrape both sides of the blade 5 against, for example, the rim of a bucket, rather than having to use another tool. In combination with the handle 1, straight side edge 2 also allows a user to properly hold the trowel in the bucket to scrape adhesive off the side of the bucket, rather than requiring a user to hold the trowel backward to load it as with a standard trowel.

(10) FIG. 2 is a front view of the trowel. Opposite straight side edge 2 is rounded side edge 3. Rounded side edge 3 offers a number of advantages over many existing trowels by allowing the blade 5 to be more compact, which allows users to use smaller buckets of adhesive that can be kept close to the worksite. Additionally, the rounded side edge 3 allows the user to alter the angle of the blade with respect to the work space, letting the notches reach areas that may be inaccessible to the standard rectangular trowel. This is especially so in light of the handle 1 disposed at the top of the blade, rather than on the back of the blade.

(11) Opposite the handle 1 and between straight side edge 2 and rounded side edge 3 is the notched bottom edge 4. Notched bottom edge 4 being opposite handle 1 offers all of the versatility previously disclosed herein, as well as allowing a user to put the notches into quite tight spaces. It also allows the user to change the angle between the plane of the blade 5 and the surface being worked upon in a much more natural motion than with a standard trowel with a back-side handle. While some uses may require a more rigid blade 5, in preferred embodiments the blade may be made of a slightly flexible material, allowing a user to make a more consistent spread as the blade yields slightly to pressure applied by the user. Typically, blade 5 will be thinner than standard trowels; for example, blade 5 may be made of 22 gauge stainless steel. In some embodiments, blade 5 may be thicker or thinner, depending at least partly on the level of flexibility desired.

(12) FIG. 3 is a depiction of a longer, narrower blade 5 having a larger radius on rounded side edge 3. Blades may be made longer or narrower to suit particular needs. As described elsewhere herein, a primary advantage of this invention is allowing a user to place the trowel in a variety of places, using the flexibility of the blade 5 and the rounded side 3 to change the angle and pressure of the blade for consistent results, even in hard to reach places. FIG. 4 is a depiction of a blade 5 having a notched edge 4 with v-notches, rather than square notches. It should be understood that while only the two most common notch types are depicted, square and v-notch, any notch shape desired by a user could be implemented with this design, including u-notches. Similarly, the particular size and spacing of notches will typically be set according to industry standards, but may be adjusted for particular uses.

(13) While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of this subject matter described herein. Furthermore, it is to be understood that the invention is defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as open terms (e.g., the term including should be interpreted as including but not limited to, the term having should be interpreted as having at least, the term includes should be interpreted as includes but is not limited to, etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases at least one and one or more to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles a or an limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases one or more or at least one and indefinite articles such as a or an (e.g., a and/or an should typically be interpreted to mean at least one or one or more); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of two recitations, without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to at least one of A, B, and C, etc. is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., a system having at least one of A, B, and C would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).

(14) While preferred and alternative embodiments of the invention have been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of these preferred and alternate embodiments. Instead, the invention should be determined entirely by reference to the claims that follow.
