[0004] [Patent Document 1] Utility Model Registration No. 3249605 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned conventional structure, if the abrasive grain surface of the polishing tape serving as the abrasive becomes clogged or deteriorates due to repeated surface finishing operations, it becomes necessary to manually fold and transport the polishing tape serving as the abrasive, which has the disadvantage of reducing the polishing workability and convenience of polishing. [Means for solving the problem]

[0006] The present invention aims to solve these inconveniences, and the invention described in claim 1 of this invention is 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 the abrasive material is a strip-shaped abrasive tape, which is folded back and positioned at the tip of the support member, and the folded back part of the abrasive material serves as an abrasive part for abrading the object to be abraded, and the handle member is provided with a tape feeding mechanism capable of folding back and transporting the strip-shaped abrasive tape.

[0007] The invention of claim 2 is characterized in that the tape feeding mechanism is provided with a feeding roll that can fold back and transport the strip-shaped abrasive tape.The invention of claim 3 is characterized in that the tip of the support member is provided with a fastening member that can fasten or release the folded-back strip-shaped abrasive to the support member.The invention of claim 4 is characterized in that the strip-shaped abrasive is attached to or detached from the support member.The invention of claim 5 is characterized in that the tip of the support member is provided with an anti-slip member for the abrasive that can be freely fitted and detached. [Effects of the Invention]

[0008] As described above, in the device of claim 1, the finishing tool comprises an abrasive material capable of polishing an object to be polished, a support member capable of supporting the abrasive material, and a handle member capable of holding the support member. The worker holds the handle member of the finishing tool, presses the folded portion of the strip-shaped abrasive material against the surface of the object to be polished, and polishes the support member in the front-back, left-right, and diagonal directions, primarily to manually finish the surface of the object to be polished, such as a mold. In this case, a strip-shaped abrasive tape is used as the abrasive material, and the strip-shaped abrasive material is folded back at the tip of the support member, with the folded portion of the abrasive material serving as the polishing portion for polishing the object to be polished. Therefore, when the abrasive surface of the abrasive tape as the abrasive material becomes clogged or deteriorates due to repeated surface finishing operations, the strip-shaped abrasive tape can be removed. This can be achieved by simply replacing the abrasive strip, and by replacing the abrasive strip, various finishing processes such as coarse, medium, fine and extra-fine can be accommodated, thereby reducing the cost of the abrasive work and improving the ease of polishing.Furthermore, since the handle member is provided with a tape feeding mechanism that can fold back and forward the abrasive strip tape, when the abrasive grain surface of the abrasive tape as abrasive becomes clogged or deteriorated due to repeated surface finishing operations, the tape feeding mechanism folds back and forwards the abrasive tape as abrasive strip at the tip of the support member, thereby revealing a new abrasive portion of the abrasive tape, and the surface of the object to be polished can be satisfactorily hand-finished using the new abrasive portion.

[0009] In the device described in claim 2, the tape feeding mechanism is provided with a feed roll that can fold back the strip-shaped abrasive tape. Therefore, when the worker rotates the feed roll with his fingers, the abrasive tape is folded back due to frictional contact between the outer surface of the feed roll and the outer surface of the abrasive tape. This allows the length of the abrasive tape to be adjusted as desired, which facilitates smooth manual finishing work. In the device described in claim 3, a fastening member is provided at the tip of the support member that can fasten or release the folded-back strip-shaped abrasive material to the support member. Therefore, after the tape feeding mechanism has folded back the abrasive tape to expose a new polishing area, when manual finishing work is performed with the strip-shaped abrasive material, the fastening member can reliably fasten and fix the abrasive tape to the support member, allowing smooth polishing. Furthermore, the tape feeding mechanism can rotate the strip-shaped abrasive tape, which allows the worker to adjust the length of the abrasive tape as desired. When the abrasive is unwound and rotated to reveal a new abrasive section, the abrasive tape can be easily released from the support member using the fastening member, making it easy to fold back the strip abrasive, revealing a new abrasive section and allowing for good hand finishing work using the new abrasive section.In the device described in claim 4, the strip abrasive is attached to and detached from the support member so that it can be easily attached to the support member, while also being easily detached, making it easy to replace the strip abrasive.In the device described in claim 5, a non-slip member for the abrasive is attached to the tip of the support member so that it can be easily fitted and detached, preventing the strip abrasive from slipping, thereby improving the ease of polishing and the convenience of polishing.

[0011] 1 to 12 show embodiments of the present invention, with FIGS. 1 to 8 showing a first embodiment and FIGS. 9 to 12 showing a second embodiment.

[0012] 1 to 8, the finishing tool T is broadly composed of an abrasive material 1 capable of abrading a 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. In this case, the abrasive material 1, the support member 2, and the handle member 3 are made of synthetic resin. However, they may also be made of metals other than synthetic resin, such as iron or aluminum, or bamboo.

[0013] In this case, as shown in Figures 1, 2 and 8, a strip-shaped abrasive tape F is used as the abrasive material 1, and an abrasive surface F1 is formed only on the surface of the abrasive tape F. The strip-shaped abrasive material 1 is folded back at the tip 2e of the support member 2, and the abrasive surface F1 is arranged on the outer surface, which is one surface, of the abrasive tape F. The abrasive surface F1 on the outer surface of the folded back portion 1U of the abrasive material 1 serves as the polishing section K for polishing the workpiece W.

[0014] In this case, as shown in Figures 1, 2 and 4, the handle member 3 is provided with a tape payout mechanism Q capable of folding back and transporting the strip-shaped polishing tape F, and this tape payout mechanism Q is provided with a payout roll 6 capable of folding back and transporting the strip-shaped polishing tape F.

[0015] In this case, as shown in Figures 1, 2, 4 and 5, the tape payout mechanism Q has a pair of opposing bearing pieces 3e·3e formed on the upper surface of the handle member 3, a through hole 3f formed between the pair of opposing bearing pieces 3e·3e on the front upper surface of the handle member 3, and the roll shaft 6a·6a of the payout roll 6 is rotatably supported between the bearing pieces 3e·3e, so that the outer peripheral surface of the payout roll 6 protrudes from the through hole 3f and comes into contact with the outer abrasive grain surface F1, which is the surface of the abrasive tape F.

[0016] 2, 4 and 6, the support member 2 is formed in the shape of a square plate, the handle member 3 is formed in the shape of a square tube, the upper rear surface of the support member 2 is formed as an inclined surface 2a, the bottom rear surface of the support member 2 is formed as a flat surface 2b, and inclined convex portions 3b·3b that fit into the inclined surface 2a are formed on both sides of the square hole 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 wedging action of the inclined surfaces 2a and the inclined convex portions 3b·3b. In this case, the upper rear surface of the handle member 3 is formed with an opening 3c, and a detachable cover member 3d is formed in the opening 3c, making it easy to replace the strip-shaped abrasive 1.

[0017] 2, 3, 7, and 8, a fastening member 4 capable of fastening or releasing the folded-over strip-shaped abrasive material 1 to or from the support member 2 is provided at the tip 2e 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 as a square tube, and an inclined surface 4b that fits the inclined surface 2c on the front upper surface of the support member 2 is formed on the inner surface of the square hole 4a of the fastening member 4, and the fastening member 4 is arranged in the longitudinal direction of the handle member 3 as shown in FIG. In FIG. 4, by moving backward in the direction of the solid arrow, the strip-shaped abrasive 1 is fastened to the support member 2 by the wedge action between the inclined surfaces 2c and 4b, and by moving forward in the direction of the dashed arrow in FIG. 4, the wedge action between the inclined surfaces 2c and 4b is released and the strip-shaped abrasive 1 is released from the support member 2; therefore, by moving the fastening member 4 back and forth in the forward and backward directions, the wedge action between the inclined surfaces 2c and 4b can be used to fasten or release the folded-back strip-shaped abrasive 1 to or from the support member 2.

[0018] In this case, as shown in Figures 2, 4 and 6, the strip-shaped abrasive 1 is attached to or detached from the support member 2 so that both ends of the strip-shaped abrasive 1 folded back at the tip 2e of the support member 2 are placed in the square hole 3a of the handle member 3, thereby allowing the strip-shaped abrasive 1 to be attached to or pulled out and detached from the support member 2.

[0019] In this case, as shown in Figures 1 and 2, an anti-slip member 5 for the abrasive 1 is removably attached to the tip 2e of the support member 2, and this anti-slip member 5 is made of urethane rubber, which has a large friction coefficient.In place of urethane rubber, various synthetic resins with rubber elasticity may also be used, and the anti-slip member 5 is removably attached to the tip 2e 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, 4, and 8, an operator holds the handle member 3 of the finishing tool T, which includes an abrasive 1 capable of polishing an object W to be polished, a support member 2 capable of supporting the abrasive 1, and a handle member 3 capable of holding the support member 2, presses the folded portion 1U of the strip-shaped abrasive 1 against the surface of the object W to be polished, and polishes the support member 2 in the front-rear direction FB, the left-right direction LR, and diagonal directions by the operator, thereby manually finishing the surface of the object W to be polished as a mold. In this case, a strip-shaped polishing tape F is used as the abrasive 1, and the strip-shaped abrasive 1 is folded back and arranged at the tip end 2e of the support member 2, with the folded portion 1U of the abrasive 1 serving as the polishing portion K for polishing the object W to be polished. Therefore, repeated surface finishing operations can cause clogging of the abrasive grain surface F1 of the polishing tape F as the abrasive 1. When clogging or deterioration occurs, it can be dealt with by replacing only the strip-shaped abrasive 1, and by replacing the strip-shaped abrasive 1, it is possible to respond to various finishing processes such as coarse, medium, fine, and extra-fine grits, thereby reducing the cost of the abrasive work and improving the abrasive workability and convenience.Furthermore, since the handle member 3 is provided with a tape feeding mechanism Q that can fold back and forward the strip-shaped abrasive tape F, when clogging or deterioration occurs in the abrasive grain surface F1 of the abrasive tape F as the abrasive 1 due to repeated surface finishing work, the tape feeding mechanism Q folds back and forwards the abrasive tape F as the strip-shaped abrasive 1 at the tip 2e of the support member 2, thereby revealing the abrasive portion K of a new abrasive tape F, and the surface of the workpiece W can be satisfactorily hand-finished using the new abrasive portion K.

[0021] In this case, as shown in Figure 1, the tape payout mechanism Q is provided with a payout roll 6 that can return the strip-shaped polishing tape F. The worker rotates the payout roll 6 with his fingers in the direction of the arrows shown in Figures 3 and 4, and the polishing tape F is returned due to frictional contact between the outer surface of the payout roll 6 and the outer surface of the polishing tape F. This allows the payout length of the polishing tape F to be adjusted as desired, thereby making it easier to perform manual finishing work.

[0022] 2, 3, 7 and 8, a fastening member 4 capable of fastening or releasing the folded-back strip-shaped abrasive 1 to or from the support member 2 is provided at the tip 2e of the support member 2. Therefore, when the polishing tape F is folded back and transported by the tape feeding mechanism Q to expose a new polishing portion K and then manual finishing work is performed with the strip-shaped abrasive 1, the fastening member 4 can reliably fasten and fix the polishing tape F to the support member 2, allowing for good polishing. Furthermore, when the tape feeding mechanism Q feeds and rotates the strip-shaped abrasive 1 to expose a new polishing portion K, the fastening member 4 can easily release the polishing tape F from the support member 2, allowing the strip-shaped abrasive 1 to be easily folded back and transported, and the new A new polishing section K can be revealed, and hand finishing work can be performed smoothly using the new polishing section K.In this case, as shown in Figures 2, 4 and 6, the strip-shaped abrasive 1 is freely attached to and detached from the support member 2, so that the strip-shaped abrasive 1 can be easily attached to the support member 2, and on the other hand, the strip-shaped abrasive 1 can be easily detached, making it easy to replace the strip-shaped abrasive 1.In this case, as shown in Figures 1 and 2, an anti-slip member 5 for the abrasive 1 is freely attached to and detached from the tip 2e of the support member 2, so that the anti-slip member 5 can prevent the strip-shaped abrasive 1 from slipping, thereby improving the ease of polishing work and the convenience of polishing.

[0023] In the second embodiment shown in Figs. 9 to 12, the front side of the support member 2 of the first embodiment is bent upward.

[0024] In this second embodiment, the same effect as in the first embodiment can be obtained, and since the front side of the support member 2 is bent upward, it can accommodate working postures and the inclination of the surface of the workpiece W to be polished, thereby improving the polishing workability and convenience.

[0025] It should be noted that the present invention is not limited to the above-described embodiment, and the structure and shape of the workpiece W, polishing section K, polishing tape F, tape feeding mechanism Q, abrasive 1, folded portion 1U, support member 2, tip portion 2e, handle member 3, fastening member 4, anti-slip member 5, and feeding roll 6 may be appropriately modified and designed.

[0026] It is also possible to prepare a plurality of finishing tools T each having a strip-shaped abrasive material 1 with a coarse, medium, fine, or extra-fine grit, etc., to accommodate various finishing processes.

[0027] As described above, the intended purpose can be fully achieved. [Explanation of symbols]
