## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to cutting tools, and more particularly, to a sandpaper cutting tool and method of same for cutting sandpaper to the exact measurements required for a 1⁄4 sheet sander. The sandpaper cutting tool is lightweight and uniquely designed having two pre-measured flat cutting surfaces each having two serrated blades for quickly and easily cutting full sized sheets of sandpaper into four one-quarter size pieces of sandpaper.
For any member of the woodworking profession, or the millions of do-it-yourself home improvement experts, a sander is an indispensable tool, particularly the 1⁄4 sheet sander which is the industry standard. The widely used 1⁄4 sheet sander requires sandpaper in a specific size in order to fit properly. The 1⁄4 sheet sander contains a pad measuring approximately four and one-half inches by four and one-half inches (4.5′′×4.5′′) on which a piece of sandpaper is secured. A one quarter sheet of sandpaper measuring five and one-half by four and one-half inches (5×41⁄2′′) is inserted underneath the pad, and the ends of the sandpaper are folded up and over the edges of the pad and secured by clips. The sander uses a motor that moves the pad in a back and forth, circular motion at a high speed, allowing the user to remove material fairly quickly and easily.
A frustrating feature of using the 1⁄4 sheet sander is obtaining the correct size sandpaper. Currently, store bought sandpaper only comes in large sheets measuring nine by eleven inches (9×11′′) or pre-cut squares. Pre-cut squares are expensive, leaving the average consumer with the alternative of buying large sheets and manually cutting them to achieve the correct size.
There is no process for quickly measuring and cutting sandpaper. The user must first measure the correct specifications. Once the correct dimensions are measured, the most common way of cutting the sandpaper is using a knife or scissors, and this method is both imprecise and time consuming. Furthermore, cutting sandpaper dulls the knife or scissors, leaving them less useful for Other tasks. The present invention seeks to resolve the foregoing issues by providing a quick and easy means to measure and cut correctly the exact size sandpaper for use in a 1⁄4 sheet sander.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates a sandpaper cutting tool 10 specially designed for easily and efficiently cutting sandpaper to the precise dimensions required for use with a 1⁄4 sheet sander. In its broadest context, the tool 10 has a platform 12 having a plurality of surfaces 14, and at least two blades 16 for creating precise, straight, and even cuts.
The sandpaper cutting tool 10 is particularly useful for cutting a nine by eleven inch (9×11′′) sheet of sandpaper into equal quarters of five and one-half by four and one-half inches (51⁄2×41⁄2′′) for use with a standard 1⁄4 sheet sander. The sheet sander is a hand held tool well known in the construction and woodworking art industry to sand wood to a smooth surface. However, the 1⁄4 sheet sander requires sandpaper in a specific size in order to fit properly for use. This size requirement proves frustrating as sandpaper is only available for purchase in full sheet sizes or pre-cut quarters, which are expensive.
In the preferred embodiment, the platform 12 of the tool 10 is substantially rectangular and measures eleven inches (11′′) in length, by eleven and three-sixteenths inches (11 3/16′′) in width. The platform 12 has a front 13 and a back 15. In the preferred embodiment, the multi-tiered platform 12 includes a plurality of surfaces 14 extending between the front 13 and back 15. Preferably, the platform 12 includes two rectangular flat measuring surfaces 14, specifically a first measuring surface 14A and a second measuring surface 14B, both aligned vertically along the back 15. The platform 12 has a top surface 14C positioned on top of the second measuring surface 14B which is also aligned with the first and second measuring surfaces 14A and 14B along the back 15.
The surfaces 14 are stacked vertically on top of one another, thereby defining a tiered or step like tool 10. Such that the first measuring surface 14A creates a base with the second measuring surface 14B positioned atop the first measuring surface 14A near the back 15 of the platform 12. A top surface 14C is posited atop the second measuring surface 14B near the back 15. The three surfaces 14 are vertically aligned and define the back 15 of the platform 12. The first measuring surface 14A is one-half inch (1⁄2′′) in height, the second measuring surface 14B is one-half inch (1⁄2′′) in height and the top surface 14C is one-half (1⁄2′′) in height. Therefore, with all three surfaces 14 in position, the platform 12 is one-half inch (1⁄2′′) in height at the front 13 along the first measuring surface 14A, and increases to one inch (1′′) in height along the second measuring surface 14B and finally increases to one and one-half inches (11⁄2′′) in height at the back 15. A first backstop 31 is defined between the first measuring surface 14A and the second measuring surface 14B. A second backstop 35 is defined between the second measuring surface 14B and the top surface 14C. Preferably, the platform 12 is constructed from wood or a tough, lightweight and durable injection-molded thermoplastic. The lightweight design allows the user to easily transport the tool 10 to and from a construction site.
The first measuring surface 14A has a front cutting edge 20 and a back stopping edge 22 for allowing the sandpaper to align correctly and rest atop the first Measuring surface 14A when positioned. Coupled to the first measuring surface 14A near the front cutting edge 20 is a first blade 16A for easily cutting sandpaper. The first blade 16A is preferably ten and thirteen-sixteenths inches (10 13/16′′) in length. Preferably, the first blade 16A is made out of steel. In alternate embodiments wherein the platform 12 is made from thermoplastic, the first blade 16A is also made from thermoplastic. The first blade 16A has a serrated edge 24 positioned along the front cutting edge 20 such that the serrated edge 24 is vertically aligned adjacent the front cutting edge 20. This allows for easily cutting a piece of sandpaper with straight, clean lines. In the preferred embodiment, the first blade 16A is coupled to the first measuring surface 12A by screws 18. Other coupling means are contemplated to secure the first blade 16A to the first measuring surface 14A.
An opening 19 is defined between the first blade 16A and the first measuring surface 14A. Preferably, the opening 19 is one thirty-second of an inch ( 1/32′′). The opening 19 allows the user to insert a sheet of sandpaper 30 (shown in FIG. 3) between the first blade 16A and first measuring surface 14A such that the sandpaper 30 is positioned underneath the first blade 16A and positioned atop the first measuring surface 14A for cutting the sandpaper 30 into the desired dimension. The first measuring surface 14A is precisely designed such that as the sandpaper 30 is inserted through the opening 19, the first backstop 31 provides a barrier for the sandpaper 30 allowing the exact dimension required to cut the sandpaper 30 in half. Thus, when the serrated edge 24 of the first blade 16A is used to cut the sandpaper 30, the full sheet of sandpaper 30 is split exactly in half, yielding cut sandpaper of nine inches by five and one-half inches (9×51⁄2).
Similarly, the second measuring surface 14B has a front cutting edge 32 and a back stopping edge 34. Coupled to the second measuring surface 14B near the front cutting edge 32 is a second blade 16B. The second blade 16B is similar in dimensions and material as the first blade 16A. The second blade 16B has a serrated edge 36 positioned along the front cutting edge 32 such that the serrated edge 36 is vertically aligned adjacent the front cutting edge 32 for easily cutting the sandpaper 30. In the preferred embodiment, the second blade 16B is coupled to the second measuring surface 14B by screws 18. Other coupling means are contemplated to secure the second blade 16B to the second measuring surface 14B.
An opening 36 is defined between the second blade 16B and second measuring surface 14B. Preferably, the opening 36 is one thirty-second of an inch ( 1/32′′). The opening 36 allows the user to insert a half sheet of sandpaper 40 (shown in FIG. 4) between the second blade 16B and second measuring surface 14B such that the half sheet of sandpaper 40 is positioned underneath the second blade 16B and atop the second measuring surface 14B for cutting the half sheet of sandpaper 40 into the desired dimension. The second measuring surface 14B is precisely designed such that as the half sheet of sandpaper 40 is inserted through the opening 36, the second backstop 35 provides a barrier for the half sheet of sandpaper 40 allowing the exact dimensions required to the cut the half sheet of sandpaper 40 in half. Thus, when the serrated edge 36 of the second blade 16B is used to cut the half sheet of sandpaper 40, two quarter pieces measuring five and one-half by four and one-half inches (51⁄2×41⁄2) are yielded. Thus providing sandpaper with the exact dimensions required for the 1⁄4 sheet sander.
The first backstop 31 of the platform 12 is defined between the back stopping edge 22 of the first measuring surface 14A and the front cutting edge 32 of the second measuring surface 14B. Similarly, the second backstop 35 is defined between the back stopping edge 34 of the second measuring surface 14B and the top surface 14C. The first and second backstops 31, 35 are flat rectangular panels which provide the barrier for aligning the sandpaper atop the first and second measuring surfaces 14A, 14B and adjacent the front cutting edges 20, 32. When the sandpaper is aligned the exact dimensions are achieved for cutting.
In alternate embodiments, a first securing means 33 (shown in FIG. 2) is coupled to the first backstop 31. The first securing means 33 is similar to a clip such that the first securing means secures the sandpaper 30 to the first measuring surface 14A adjacent the first backstop 31. Similarly, a second securing means 37 is coupled to the second backstop 35. The second securing means 37 is similar to a clip such that the second securing means 37 secures the half sheet of sandpaper 40 to the second measuring surface 14B adjacent the second backstop 35.
In one alternate embodiment, a non-slip means is coupled to a bottom 23, preferably corner, of the first measuring surface 14A. Preferably, the non-slip means is similar to four legs 17 (shown in FIG. 2) which extend perpendicularly downward from the first measuring surface 14A. The legs 17 balance the cutting tool 10 on a flat surface for use. Preferably, the legs 17 are one-quarter inch (1⁄4′′) in length and each leg 17 is rubber tipped which prevents the cutting tool 10 from slipping when placed on any flat surface.
In one alternate embodiment, at least two screw holes 41 (shown in FIG. 2) are positioned through the first and second measuring surfaces 14A, 14B of the platform 12. The screw holes 41 allow the user to easily and quickly couple the cutting tool 10 to a work bench, thereby making the cutting tool 10 easily accessible at a construction site.
FIGS. 3-4 illustrate the method of using the sandpaper cutting tool 10 to cut a nine by eleven inch (9×11′′) sheet of sandpaper 30 into four quartets for use in a 1⁄4 sheet sander 50 (shown in FIG. 5). First, the user inserts a full size standard sheet of sandpaper 30 into the opening 19 between the first blade 16A and the first measuring surface 14A. The user slides the sandpaper 30 along the first measuring surface 14A until the sandpaper 30 is stopped by and positioned adjacent the first backstop 31. The screws 18 coupling the first blade 16A to the first measuring surface 14A are positioned such that the sandpaper 30 is insertable through the opening 19 by only a nine inch width, thereby ensuring that the first cut made by the user is along the eleven inch length. When the sandpaper 30 is in position, two half's of the sandpaper are defined, specifically an inner half 30A and an outer half 308. The inner half 30A is positioned atop the first measuring surface 14A flush against the first backstop 31. The outer half 30B extends horizontally underneath the opening 19 outwardly from the front cutting edge 20 of the first measuring surface 14A. Next, the user secures the sandpaper 30 by applying downward pressure to the inner half 30A of the sandpaper 30 against the first measuring surface 14A. The user then cuts the sandpaper 30 by pulling upwardly the outer half 30B of the sandpaper 30 at approximately a ninety-degree angle along the serrated edge 24 of the first blade 16A. Unlike the prior art, pulling upwardly at approximately a forty-five degree angle or approximately a one hundred and thirty-five degree angle will still yield the same perfect cut. Preferably, a ninety degree angle and upward pulling motion allows the user to obtain a clean, straight edge cut. When complete, two half sheets of sandpaper 40 result (FIG. 4), each five and one-half inches (5′′) in length, by nine inches (9′′) in width.
The user then sets the sandpaper 40 into position for the final cut by rotating one of the half sheets of sandpaper 40 ninety degrees (90°), and inserting the half sheet of sandpaper 40 into the opening 32 between the second blade 16B and the second measuring surface 12B. In a similar manner, the user applies downward pressure to the inner half 40A of the sandpaper 40 against the second measuring surface 14B while pulling the outer half 40B of sandpaper 40 in an upward ninety degree angle along the serrated edge 36 of the second blade 268. Unlike the prior art, pulling upwardly at approximately a forty-five degree angle approximately a one hundred and thirty-five degree angle will still yield the same perfect cut. This second cut yields two pieces of one-quarter sheet sandpaper 42 (FIG. 4), each five and one-half inches (51⁄2′′) in length by four and one-half inches (41⁄2′′) in width. Repeating the method to the second half sheet of sandpaper 40 yields four, quarter size pieces of sandpaper 42. Thereby, achieving the exact dimensions required for sandpaper for use in a 1⁄4 sheet sander 50.
FIG. 5 illustrates a 1⁄4 sheet sander 50 well known in the art. The sandpaper 42 is cut using the tool 10 of the present invention to the required dimensions and is ready for insertion into the 1⁄4 sheet sander for use sanding wood or other like materials.
In conclusion, herein is presented a sandpaper cutting tool and method of same for cutting sandpaper into the exact dimensions for use with a 1⁄4 sheet sander. The invention is illustrated by example in the drawing figures, and throughout the written description.
