Aspects of this document relate generally to systems for using a tile removal raking apparatus capable of raking or otherwise gathering chipped tile while removing dust disturbed during the tile removal process.
Standard stand-up rakes are sometimes used in the tile removal process. After tile has been chipped away from a floor surface, standard stand-up rakes may be used to sweep up or otherwise gather and dispose of the leftover pieces of tile. However, these tools do not pick up dust that is disturbed and subsequently suspended in the air during the raking process. Free floating dust particles may be inhaled or otherwise consumed by rake users. Many of these particles can be toxic when consumed and may cause health problems to users over time.
Furthermore, stand-up rakes are often bulky and difficult to maneuver in tight spaces creating the risk of damage to walls, cabinets, and other objects.
The present disclosure provides a dust free tile removal tool. The dust free tile removal tool may include among other things a hollow base member 1. The hollow base member 1 may be any of a number of shapes and sizes. For example, in one embodiment of many, the hollow base member 1 may be rectangular and no larger than a shoe box. In another embodiment, the hollow base member 1 may be cylindrical. In yet other embodiments, the hollow base member may be a mixture of shapes. In a preferred embodiment, the hollow base member is substantially similar to a triangular prism with rectangular prisms on either end.
The hollow base member may include an opening 17 for receiving a vacuum source. The opening 17 may be configured to couple to a vacuum hose or other vacuum source. In a preferred embodiment the opening 17 is circular, but the opening may also be rectangular, triangular, square or any other shape capable of receiving a vacuum source. In one embodiment of many, a hollow cylinder 9 extends outward from the hollow base member 1 allowing a vacuum source such as a vacuum hose to couple to the cylinder 9. In other embodiments, a hollow rectangle or a hollow elliptical cylinder may extend from the hollow base member 1 and be configured to couple to a vacuum source.
The above described openings may be configured to couple to a vacuum source in many ways. In one embodiment, the opening 17 may be threaded to allow the vacuum hose to screw on. In another embodiment, the opening 17 or cylinder 9 may be a fitted shape and size that allows a vacuum hose to slide into the opening 17 or onto the cylinder 9 such that friction maintains the attachment. In other embodiments, attachment of a vacuum source may be achieved with clips, magnets, rivets, or any other connection mechanism capable of attaching a vacuum source to the dust free tile removal tool.
The dust free tile removal tool may further comprise a hollow rake member 3 that is in fluid communication with the hollow base member 1. The connection of the hollow rake member 3 and the hollow base member 1 may form an obtuse angle. Substantially opposite the end 12 of the hollow rake member 3 that is in fluid communication with the hollow base member 1, the hollow rake member 3 may have openings 15 to allow dust to flow through the dust free tile removal tool. The hollow rake member 3 may also have openings 13 on a top surface 10. The openings may be circular, elliptical, rectangular, triangular, square, amorphous or any other shape or combination of shapes through which air may flow. The size of the openings may be as large as four inches on their longest side and as small as one millimeter or less. In a preferred embodiment, the openings are rectangular with two hemispheres on either end of the rectangle. In some embodiments in which the openings are circular, the openings may be up to two inches in diameter. In other embodiments win which the openings are circular, the openings may be as small as one millimeter in diameter. The hollow rake member 3 may be any of a number of shapes. In a preferred embodiment the hollow rake member 3 is a rectangular prism with openings 13 on a top surface 10 and openings 15 on a front surface 14. In other embodiments the hollow rake member 3 may be a triangular prism, cube, or a combination of shapes.
The hollow rake member 3 may further include rake tines 11 extending outward from the hollow rake member 3. There may be as many or as few rake tines 11 as are necessary to rake or otherwise gather chipped tile material. In a preferred embodiment there may be six rake tines 11 spread evenly and extending from the hollow rake member 3. In some embodiments, however, there may be only two rake tines 11 or twenty or more rake tines 11. In some embodiments, openings 15 may exist between the rake tines 11 in the hollow rake member 3. Each of the rake tines 11 may be any substantially rigid material. In some embodiments, the rake tines 11 may be made of metal such as steel, iron, or titanium. In another embodiment the rake tines 11 may be plastic, rubber, glass, or a synthetic or composite material. In yet another embodiment, the rake tines 11 may be made up of different materials in different parts of the rake tines 11. For example, the outermost portion of the rake tines 11 may be plastic while the portion of the rake tines 11 connected to the hollow rake member 3 is metal.
The dust free tile removal tool may further comprise a left strut 5 and a right strut 4 extending from a bottom surface 19 of the dust free tile removal tool. In one embodiment the left strut 5 and the right strut 4 may be attached to a bottom surface 19 of the hollow base member 1. In another embodiment the struts may be attached to a bottom surface of the hollow rake member. One of ordinary skill in the art would appreciate that the struts may be any shape and material capable of transferring force from a handle 7 to the dust free tile removal tool. In some embodiments the dust free tile removal tool may have a single strut connected to the handle near its midpoint. In other embodiments, a single strut may be attached to the handle at one end. One of ordinary skill in the art would appreciate that the struts may be any length sufficient to allow a human hand to comfortably fit between a handle 7 and the hollow base member 1.
A handle 7 may span between the left strut 5 and the right strut 4. The handle 7 may be located a sufficient distance from the vacuum end 2 of the hollow base member 1 to allow the user's forearm to make contact with the hollow base member 1. The force couple formed by the downward force exerted by the user on the handle 7 and the upward force from the forearm to the hollow base member 1 may allow the user to exert force from the rake tines on chipped tile material. Without the contact point between the forearm and the hollow base member 1, a user's hand may simply rotate around the handle 7 when attempting to rake up tile material.
The handle 7 may be any shape that enables a hand to wrap around it. In some embodiments the handle 7 is cylindrical. In other embodiments the handle 7 may have grooves for fingers. In yet other embodiments, the handle 7 may have depressions or protrusions such as small nodes that improve grip. In a preferred embodiment the handle 7 is an elliptical cylinder. The handle may also be made of any material including rubber, plastic, metal, or a composite or synthetic material. Furthermore, the handle 7 may be solid or hollow.
Aspects and applications of the invention presented here are described below in the drawings and detailed description of the invention. Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. The inventor is fully aware that he can be his own lexicographer if desired. The inventor expressly elects, as his own lexicographers, to use only the plain and ordinary meaning of terms in the specification and claims unless he clearly states otherwise and then further, expressly sets forth the “special” definition of that term and explains how it differs from the plain and ordinary meaning. Absent such clear statements of intent to apply a “special” definition, it is the inventor's intent and desire that the simple, plain and ordinary meaning to the terms be applied to the interpretation of the specification and claims.
The inventor is also aware of the normal precepts of English grammar. Thus, if a noun, term, or phrase is intended to be further characterized, specified, or narrowed in some way, then such noun, term, or phrase will expressly include additional adjectives, descriptive terms, or other modifiers in accordance with the normal precepts of English grammar. Absent the use of such adjectives, descriptive terms, or modifiers, it is the intent that such nouns, terms, or phrases be given their plain, and ordinary English meaning to those skilled in the applicable arts as set forth above.
Further, the inventor is fully informed of the standards and application of the special provisions of AIA 35 U.S.C. § 112(f). Thus, the use of the words “function,” “means” or “step” in the Detailed Description or Description of the Drawings or claims is not intended to somehow indicate a desire to invoke the special provisions of AIA 35 U.S.C. § 112(f), to define the invention. To the contrary, if the provisions of AIA 35 U.S.C. § 112(f) are sought to be invoked to define the inventions, the claims will specifically and expressly state the exact phrases “means for” or “step for, and will also recite the word “function” (i.e., will state “means for performing the function of [insert function]”), without also reciting in such phrases any structure, material or act in support of the function. Thus, even when the claims recite a “means for performing the function of . . . ” or “step for performing the function of . . . ,” if the claims also recite any structure, material or acts in support of that means or step, or that perform the recited function, then it is the clear intention of the inventor not to invoke the provisions of AIA 35 U.S.C. § 112(f). Moreover, even if the provisions of AIA 35 U.S.C. § 112(f) are invoked to define the claimed inventions, it is intended that the inventions not be limited only to the specific structure, material or acts that are described in the preferred embodiments, but in addition, include any and all structures, materials or acts that perform the claimed function as described in alternative embodiments or forms of the invention, or that are well known present or later-developed, equivalent structures, material or acts for performing the claimed function.
