[0004] [Patent Document 1] Utility model registration No. 3151058 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the case of the above-mentioned conventional structure, when the grinding stone used as an abrasive deteriorates due to repeated surface finishing operations, the entire finishing tool must be replaced. Furthermore, various types of grinding stones are available, such as coarse, medium, fine and extra fine, and therefore multiple entire finishing tools must be prepared, which has the disadvantage of reducing the ease of polishing using the finishing tool, increasing the cost of polishing operations and reducing the convenience of polishing. [Means for solving the problem]

[0006] The present invention aims to solve these inconveniences, and the invention described in claim 1 relates to a finishing tool comprising an abrasive material capable of abrading an object to be abraded, a support member capable of supporting the abrasive material, and a handle member capable of holding the support member, wherein a strip of abrasive tape is used as the abrasive material, the strip of abrasive material is folded back around the tip of the support member, and the folded back portion of the abrasive material serves as an abrasive part for abrading the object to be abraded.

[0007] The invention described in claim 2 is characterized in that a fastening member is provided at the tip of the support member, which can fasten or release the folded-over strip of abrasive to or from the support member. The invention described in claim 3 is characterized in that the strip of abrasive is provided so as to be freely attached or detached from the support member. The invention described in claim 4 is characterized in that an anti-slip member for the abrasive is provided at the tip of the support member, which can be freely fitted and detached.

[0008] The invention described in claim 5 is characterized in that a plate-shaped abrasive is used as the abrasive instead of the strip-shaped abrasive, and the plate-shaped abrasive is placed between the object to be polished and the support member, and the support member performs an abrasive action on the plate-shaped abrasive to perform polishing.The invention described in claim 6 is characterized in that a non-slip member for the abrasive is provided at the tip of the support member so that it can be freely fitted and removed. Effect of the Invention

[0009] As described above, in the device of claim 1, the worker holds the handle of a finishing tool, which is made up of an abrasive capable of polishing an object to be polished, a support member capable of supporting the abrasive, and a handle member capable of holding the support member, presses the folded portion of the strip of abrasive against the surface of the object to be polished, and polishes the surface of the object to be polished by the worker by moving the support member in the front-back, left-right and diagonal directions. In this case, a strip of abrasive tape is used as the abrasive, and the strip of abrasive is folded back and placed at the tip of the support member, and the folded portion of the abrasive serves as the polishing part for polishing the object to be polished. Therefore, when the abrasive deteriorates due to repeated surface finishing work, it is possible to deal with the problem by replacing only the strip of abrasive. Furthermore, by replacing the strip of abrasive, it is possible to deal with various finishing processes such as coarse, medium, fine and extra fine, thereby reducing the cost of the polishing work and improving the convenience of polishing.

[0010] In the device described in claim 2, a fastening member is provided at the tip of the support member, which can fasten or release the folded-over strip of abrasive to or from the support member. This allows the strip of abrasive to be securely fastened to the support member, allowing for good polishing. On the other hand, the strip of abrasive can be easily released from the support member, allowing for easy replacement of the strip of abrasive. In the device described in claim 3, the strip of abrasive is provided so as to be freely attached or detached from the support member, allowing for easy attachment of the strip of abrasive to the support member. On the other hand, the strip of abrasive can be easily detached, allowing for easy replacement of the strip of abrasive. In the device described in claim 4, a non-slip member for the abrasive is provided at the tip of the support member, which can be freely fitted and detached. This prevents the strip of abrasive from slipping, thereby improving the ease of polishing and the convenience of polishing.

[0011] In addition, in the device described in claim 5, an operator holds a handle member of a finishing tool, which comprises an abrasive capable of polishing an object to be polished, a support member capable of supporting the abrasive, and a handle member capable of holding the support member, presses a plate-shaped abrasive against the surface of the object to be polished with the tip of the support member, and polishes the surface of the object to be polished manually by moving the plate-shaped abrasive in the front-rear, left-right and diagonal directions of the support member. In this case, the plate-shaped abrasive is used as the abrasive, and is placed between the object to be polished and the support member, and the polishing surface of the plate-shaped abrasive serves as the polishing part that polishes the object to be polished. Therefore, when the abrasive deteriorates due to repeated surface finishing operations, it is possible to deal with the problem by replacing only the plate-shaped abrasive, and by replacing the plate-shaped abrasive, it is possible to handle various finishing processes such as coarse, medium, fine, and extra-fine, thereby reducing the cost of the abrasive work and improving the ease and convenience of the abrasive work.Furthermore, in the device described in claim 6, an anti-slip member for the abrasive is provided at the tip of the support member so that it can be freely fitted and detached, so that the plate-shaped abrasive can be prevented from slipping by the anti-slip member, thereby improving the ease and convenience of the abrasive work.

[0013] 1 to 17 show examples of embodiments of the present invention, with Figs. 1 to 7 being a first embodiment example corresponding to the inventions of claims 1, 2, 3 and 4, Figs. 8 to 10 being a second embodiment example corresponding to the inventions of claims 5 and 6, Figs. 11 to 14 being a third embodiment example showing an alternative structure to the first embodiment, and Figs. 15 to 17 being a fourth embodiment example showing an alternative structure to the second embodiment.

[0014] In the first embodiment example of Figures 1 to 7, the finishing tool T is broadly composed of an abrasive material 1 capable of abrading the workpiece W, a support member 2 capable of supporting the abrasive material 1, and a handle member 3 capable of holding the support member 2.

[0015] In this case, as shown in Figures 1, 2 and 7, a strip-shaped polishing tape F is used as the abrasive material 1, and the strip-shaped polishing material 1 is folded back and positioned at the tip of the support member 2, with the folded back portion 1U of the abrasive material 1 being used as the polishing section K for polishing the workpiece W.

[0016] 2, 4 and 5, the support member 2 is formed in a square plate shape, the handle member 3 is formed in a square tube shape, the rear upper surface of the support member 2 is formed in an inclined surface 2a, the rear bottom surface of the support member 2 is formed in a flat surface 2b, and inclined convex portions 3b·3b that fit the inclined surface 2a are formed on both sides of the square hole portion 3a of the square tube-shaped handle member 3, so that the support member 2 can be detachably attached to the handle member 3 by the wedge action of the inclined surface 2a and the inclined convex portions 3b·3b. In this case, the rear upper surface of the handle member 3 is formed with an opening 3c, and a detachable cover member 3d is formed in the opening 3c, so that the strip-shaped abrasive 1 can be easily replaced.

[0017] 2, 3, 6 and 7, a fastening member 4 capable of fastening or releasing the folded-over strip-shaped abrasive 1 to or from the support member 2 is provided at the tip of the support member 2, the front upper surface of the support member 2 is formed as an inclined surface 2c, the front bottom surface of the support member 2 is formed as a flat surface 2d, the fastening member 4 is formed in a square tube shape, and an inclined surface 4b that fits with the inclined surface 2c on the front upper surface of the support member 2 is formed on the inner surface of the square hole portion 4a of the fastening member 4, and by moving the fastening member 4 back and forth in the front-to-back direction FB, which is the longitudinal direction of the handle member 3, the wedge action of the inclined surfaces 2c and 4b enables the folded-over strip-shaped abrasive 1 to be fastened or released to or from the support member 2.

[0018] In this case, as shown in Figures 2, 4 and 5, the strip-shaped abrasive 1 is provided so as to be freely attached to or detached from the support member 2, and both ends of the strip-shaped abrasive 1 folded back at the tip of the support member 2 are placed in the square hole portion 3a of the handle member 3, thereby configuring the strip-shaped abrasive 1 to be freely attached to or detached from the support member 2.

[0019] In this case, as shown in Figures 1 and 2, a non-slip member 5 for the abrasive 1 is removably attached to the tip of the support member 2, and this non-slip member 5 is made of urethane rubber having a large friction coefficient. In place of urethane rubber, various synthetic resins having rubber elasticity may also be used, and the non-slip member 5 is removably attached to the tip of the support member 2 due to its inherent rubber elasticity.

[0020] Since the first embodiment has the above-mentioned configuration, as shown in Figs. 1, 2 and 7, an operator holds the handle member 3 of the finishing tool T, which is composed of an abrasive 1 capable of polishing an object to be polished W, a support member 2 capable of supporting the abrasive 1, and a handle member 3 capable of holding the support member 2, and presses the folded portion 1U of the strip-shaped abrasive 1 against the surface of the object to be polished W. The operator then performs polishing operations on the support member 2 in the front-rear direction FB, the left-right direction LR, and the oblique direction, and mainly manually finishes the surface of the object to be polished W as a mold. In this case, the strip-shaped abrasive 1 is used as the abrasive 1. An abrasive tape F is used, and the strip-shaped abrasive 1 is folded back and positioned at the tip of the support member 2, with the folded back portion 1U of the abrasive 1 serving as the abrasive section K for abrading the workpiece W. Therefore, when the abrasive 1 deteriorates due to repeated surface finishing operations, it is possible to deal with the problem by replacing only the strip-shaped abrasive 1. Furthermore, by replacing the strip-shaped abrasive 1, it is possible to accommodate various finishing processes such as coarse, medium, fine and extra-fine, thereby reducing the cost of the abrasive work and improving the ease of polishing and the convenience of polishing.

[0021] In this case, as shown in Figs. 2, 3 and 6, the end of the support member 2 is provided with a fastening member 4 capable of fastening or releasing the folded-back strip-shaped abrasive 1 to or from the support member 2. This allows the strip-shaped abrasive 1 to be reliably fastened to the support member 2, enabling good abrasive performance. On the other hand, the strip-shaped abrasive 1 can be easily released from the support member 2, allowing easy replacement of the strip-shaped abrasive 1. In this case, as shown in Figs. 2, 4 and 5, the strip-shaped abrasive 1 is fastened to the support member 2. Since the support member 2 is provided so as to be freely attached or detached, the strip-shaped abrasive 1 can be easily attached to the support member 2, while the strip-shaped abrasive 1 can be easily detached, and the strip-shaped abrasive 1 can be easily replaced. In this case, as shown in Figures 1 and 2, the anti-slip member 5 for the abrasive 1 is provided at the tip of the support member 2 so as to be freely fitted and detached, so that the anti-slip member 5 can prevent the strip-shaped abrasive 1 from slipping, thereby improving the workability and convenience of polishing.

[0022] In the second embodiment of Figures 8 to 10, similar to the first embodiment described above, the finishing tool T is broadly composed of an abrasive 1 capable of abrading the workpiece W, a support member 2 capable of supporting the abrasive 1, and a handle member 3 capable of holding the support member 2.

[0023] In this case, unlike the first embodiment, as shown in Figures 9 and 10, a plate-shaped abrasive P is used as the abrasive 1 instead of the strip-shaped abrasive F, that is, the strip-shaped abrasive F is removed from the support member 2 and the handle member 3, and a plate-shaped abrasive P is used instead of the strip-shaped abrasive F. In this case, the plate-shaped abrasive P is formed into a rectangular plate having a width dimension approximately the same as that of the support member 2, and various types of plate-shaped abrasive P, such as coarse, medium, fine, and extra-fine, are prepared. The plate-shaped abrasive P is placed between the workpiece W and the support member 2, and is replaced with various types of plate-shaped abrasive P, such as coarse, medium, fine, and extra-fine, depending on the finishing process, and the support member 2 performs a polishing operation on the plate-shaped abrasive P to perform polishing.

[0024] In this case, as shown in FIG. 8, a non-slip member 5 for the abrasive 1 is removably attached to the tip of the support member 2, and as in the first embodiment, this non-slip member 5 is made of urethane rubber having a large friction coefficient, but various synthetic resins having rubber elasticity may also be used instead of urethane rubber, and the non-slip member 5 is removably attached to the tip of the support member 2 due to its inherent rubber elasticity.

[0025] Since the second embodiment has the above-mentioned configuration, as shown in Figures 9 and 10, an operator holds the handle member 3 of a finishing tool T, which is composed of an abrasive 1 capable of polishing an object to be polished W, a support member 2 capable of supporting the abrasive 1, and a handle member 3 capable of holding the support member 2, presses the plate-shaped abrasive 1 against the surface of the object to be polished W with the tip of the support member 2, and polishes the plate-shaped abrasive 1 in the front-rear direction FB, the left-right direction LR, and an oblique direction of the support member 2 by the operator, thereby mainly manually finishing the surface of the object to be polished W as a mold. In this case, a plate-shaped abrasive P is used as the abrasive 1, and the plate-shaped abrasive P is placed between the object to be polished W and the support member 2, and the plate-shaped abrasive P is polished. Since the surface P1 is the polishing part K for polishing the workpiece W, when the abrasive 1 deteriorates due to repeated surface finishing operations, it is possible to deal with the problem by replacing only the plate-shaped abrasive 1. Furthermore, by replacing the plate-shaped abrasive 1, it is possible to handle various finishing processes such as coarse, medium, fine and extra fine, thereby reducing the cost of the abrasive work and improving the ease of polishing and the convenience of polishing. In this case, as shown in Figure 8, the anti-slip member 5 of the abrasive 1 is freely fitted and detached to the tip of the support member 2, so that the anti-slip member 5 can prevent the plate-shaped abrasive 1 from slipping, thereby improving the ease of polishing and the convenience of polishing.

[0026] In the third embodiment shown in Figures 11 to 14, the front side of the support member 2 of the first embodiment is bent upward, and in the fourth embodiment shown in Figures 15 to 17, the front side of the support member 2 of the second embodiment is bent upward.

[0027] In the third and fourth embodiments, the same action and effect as the first and second embodiments can be obtained, and since the front side of the support member 2 is bent upward, it is possible to accommodate the working posture and the inclination of the surface of the workpiece W to be polished, thereby improving the polishing workability and convenience.

[0028] Incidentally, the present invention is not limited to the above-mentioned embodiment examples, and the structures and shapes of the finishing tool T, workpiece W, abrasive 1, abrasive part K, strip-shaped abrasive tape F, plate-shaped abrasive P, folded-back part 1U, support member 2, handle member 3, fastening member 4, and anti-slip member 5 can be appropriately modified and designed.

[0029] As described above, the intended purpose can be fully achieved. [Explanation of symbols]
