Not Applicable.
The present invention generally relates to tools such as scrapers for removing residual material from cans, buckets or similar containers, and also generally relates to trowels for spreading materials on a surface.
The use of scrapers and trowels to remove various materials such as adhesives, grouts, cements, plaster, resin, stucco, paint and the like from cans, buckets or other containers is well known in the prior art. Examples of such scrapping tools are shown for example in U.S. Pat. Nos. 4,355,432; 4,627,128; 4,987,635; and 5,875,515. When using such scrapping tools to apply a material, some material is removed from the container with the tool, then the material is deposited upon the surface to which the material is to be applied such as a surface to be tiled. The user must then put the scrapping tool away and pick up a different tool such as a trowel which is then used to spread the material on the surface. This process of switching from one tool to another then back again can be time consuming and tedious. A tool which functioned to improve the efficiency of this process would be desirable.
The present invention is a combination squeegee (i.e., a scraper) and hand trowel tool. The tool can be conveniently used to first remove a material from a can, bucket or other material container and then used to spread the material evenly on a surface or substrate. The tool has a substantially flat blade having a continuous arcuate curved edge portion substantially conforming to a portion of an interior wall of a container for efficiently removing residual material from the interior wall of containers such as cans or buckets and a separate notched edge portion (preferably with indentations or serrations) for evenly spreading the material on a surface. The invention further contemplates a method of using the tool to remove material from a can, bucket or container and applying the material to a surface.
Referring now to the drawings, and more particularly to
As shown in
The notched edge 22 includes a plurality of notches 28, only a portion of which are specifically indicated by a reference numeral. The configuration of the notched edge 22 can vary widely and will depend, to a large extent, on what the tool 10 is to be used for. For example, the notched edge 22 is shown in
The blade 12 has a length 30 and a width 32 which extends perpendicularly from a center point 33 of the notched edge 22 to the curved edge 20. The length 30 and width 32 of the blade 12 will vary depending on the size of the container with which the blade 12 is used to scrape material from the sidewall of the container. That is, the blade 12 is provided with a sufficient length 30 and a sufficient width 32 so that the curved edge 20 of the blade 12 can be disposed substantially adjacent a portion of the curved interior surface or wall of the container whereby a material on the sidewall can be removed by the tool 10. For example, when using the tool 10 to remove material from the sidewall of a conventional five gallon bucket, desirable results have been obtained wherein the blade 12 of the tool 10 is provided with a length of about 10.25 inches and a width of about 6.75 inches.
As previously stated, the curved edge 30 of the blade 12 has a continuous curvature which conforms to or compliments the curvature of an inner surface of a side wall of a container with which the tool 10 is anticipated to be used. That is, the curved edge 30 of the blade 12 is void of any straight line segments. Thus, the particular size of the blade 12 of the tool 10 will be determined based upon the size of the container with which the tool 10 is to be used. Further, the material removed from the container can be tile adhesives, grouts, stucco, plaster, or other bonding materials as well as paints which are used in construction. Such containers are well known in the art. Thus, no further discussion concerning the size of such containers or the nature of such containers is deemed necessary.
As noted above, the handle 18 of the tool 10 is sized to permit a person to grip the handle so that the tool 10 can be used to scrape material from the inner surface of the sidewall of the container. Thus, the handle 18 has a length 34, a width 36 and a height 38. The length 34, width 36 and height 38 of the handle 18 can vary widely depending on the size of the blade 12. For example, desirable results have been obtained wherein the length 34 of the handle 18 is about 6.75 inches, the width 36 is about 1 inch and the height 38 is about 1.5 inches.
To enhance removal of material from the interior surface of the sidewall of the container, the curved edge 20 of the blade 12 is desirably beveled substantially as shown. The degree of beveling of the curved edge 20 of the blade 12 can vary widely. However, desirable results have been achieved wherein the curved edge 20 of the blade 12 has a bevel height 40 of about 0.125 inch and a bevel width 42 of about 0.25 inch.
As previously noted, the notched edge 22 of the blade 12 is provided with a plurality of notches 28. Each notch 28 has a notch width 44. The notched edge 22 of the blade 12 shown in

While certain patterns for the notched edge of the tools hereinbefore described have been shown, it will be readily apparent to those skilled in the art that other notch patterns can be employed in the construction of the notched edge of the tool of the present invention.
As noted before, the handle 18 of the tool 10 may be releaseably connected, i.e. detachable, from the blade 12. Shown in
The connector assembly 47 includes a female connector 48 and a male connector 49. The female connector 48 is formed integrally with the blade 12d so as to extend outwardly from an upper surface 14d of the blade 12d substantially as shown. The male connector 49 is formed on one end of the handle 18d and is adapted to matingly engage the female connector 48 so that the handle 18d can be connected to the blade 12d.
Any suitable mechanism can be used as the connector assembly 47. For example, the female connector 48 can include a housing having an opening therein with internally disposed threads and the male connector 49 can be a threaded portion on one end of the handle 18 which can be inserted within the housing for mating engagement with the threads in the housing of the female connector 48 substantially as shown. Thus, the handle 18d can be operably connected or disconnected from the blade 12d via the connector assembly 47.
Any of the tools 10-10d contemplated herein or alternate embodiments of them may be constructed of materials known to be used in the construction of trowels, squeegees, scrapers, or the like, including metals, polymers, plastics (including thermoplastics), rubber, wood, wood products, cardboard, or combinations thereof. The tools 10-10d may be flexible or rigid. The tools described herein, such as tools 10-10c, may be formed as an integral one piece construction molded from a thermoplastic material, although the tool 10d is shown as constructed of separate materials such as a separate blade 12d and a separate handle 18d which are connected together via the connector assembly 47 hereinbefore described.

The size of the container 50 can vary widely but the container 50 will typically be of a size used in various manners of construction and remodeling. Further, the size of the tool 10 and any other tools described herein, will vary and desirably be sized and configured to enhance removal of material from the interior surface 52 of the sidewalls 54 of the container 50.
It is to be understood that the dimensional relationships of the materials from which the tools 10-10d and the handles 18 and 18d are fabricated, and the components of the tools 10-10d of the invention such as the blades 12-12d or the handles 18 and 18d, can vary, as well as the configuration of the handles 18 and 18d of the tools 10-10d.
Therefore, the foregoing is considered as illustrative only of the tools 10-10d of the present invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, the tools 10-10d and their uses are not limited to the exact construction and operation shown and described, and all suitable modifications and equivalents of the tools 10-10d described herein may be resorted to, and fall within the scope of the present invention.
