<第一実施形態>
図1は本発明に係る研磨具100の側面図である。図2は本発明の研磨具100を研磨ベルト50に装着する図であり、図2(a)は本発明の研磨具100を研磨ベルト50に装着する直前の図であり、図2(b)は本発明の研磨具100を研磨ベルト50に装着した図である。
<First Embodiment>
FIG. 1 is a side view of the polishing tool 100 according to the present invention. FIG. 2 is a diagram in which the polishing tool 100 of the present invention is attached to the polishing belt 50, and FIG. 2 (a) is a diagram immediately before attaching the polishing tool 100 of the present invention to the polishing belt 50, FIG. 2 (b). Is the figure which attached the polishing tool 100 of this invention to a polishing belt 50.

第1張架部材1及び第2張架部材2はそれぞれ研磨具100の外形の一部を形成している。第1張架部材1及び第2張架部材2の端部には、連結部3が形成され、図1に示されるように屈曲可能に軸支されている。この屈曲により、研磨ベルト50への装着が容易になる。ここで、本明細書中で使用される「屈曲」とは、180度近くまで折れ曲がることも含まれるが、くの字型に折れ曲がるだけのものも含まれ、本発明の研磨具が研磨ベルトに装着する際に容易に装着できる全ての角度に折れ曲がるものを含むものとする。 The first tension member 1 and the second tension member 2 each form a part of the outer shape of the polishing tool 100. A connecting portion 3 is formed at the ends of the first tensioning member 1 and the second tensioning member 2, and is pivotally supported so as to be bendable as shown in FIG. This bending facilitates attachment to the polishing belt 50. Here, the term "bending" used in the present specification includes bending up to nearly 180 degrees, but also including bending in a dogleg shape, and the polishing tool of the present invention can be used as a polishing belt. It shall include those that bend at all angles that can be easily mounted when mounted.

図1の実施形態では、第1張架部材1の側面側は直角台形の形状となっており、第1張架部材1の連結部側端部4の反対側端部が二つの隣接する直角を持つ構造となっている。第2張架部材2の連結部側端部5は、第1張架部材1の連結部側端部4と相対するように構成されている。 In the embodiment of FIG. 1, the side surface side of the first tension member 1 has a right-angled trapezoidal shape, and two adjacent right-angled ends of the connecting portion side end portion 4 of the first tension member 1 are adjacent to each other. It has a structure with. The connecting portion side end portion 5 of the second tensioning member 2 is configured to face the connecting portion side end portion 4 of the first tensioning member 1.

図1の実施形態では第1張架部材1の形態が直角台形となったものを例示しているが、第1張架部材1の連結部側端部4の形態と、第2張架部材2の連結部側端部5の形態とが、相対する形態となっていればよい。例えば、第1張架部材1の連結部側端部4の形態が凸型の円弧状であり、第2張架部材2の連結部側端部5の形態が第1張架部材1の連結部側端部4の形態と相対する凹型の円弧状の形態であってもよい。 In the embodiment of FIG. 1, the first tension member 1 has a right-angled trapezoidal shape, but the first tension member 1 has a connection portion side end portion 4 and a second tension member. It suffices if the form of the connecting portion side end portion 5 of 2 is opposite to the form. For example, the form of the connecting portion side end portion 4 of the first tensioning member 1 is a convex arc shape, and the form of the connecting portion side end portion 5 of the second tensioning member 2 is the connection of the first tensioning member 1. It may have a concave arcuate shape opposite to the shape of the portion side end portion 4.

第1張架部材1の連結部側端部4及び第2張架部材2の連結部側端部5の少なくとも一つがそれぞれの他端部に向かって厚みが変化していくようにしてもよい。連結部側端部4,5からそれぞれの他端部に向かって厚みを薄くなるようにすれば、様々な形状の部材の細かい部分にまでヤスリを当てることが可能となる。他方、連結部側端部4,5からそれぞれの他端部に向かって厚みを厚くなるようにすれば、大きな面の部材にヤスリを掛け易くなる。 At least one of the connecting portion side end portion 4 of the first tensioning member 1 and the connecting portion side end portion 5 of the second tensioning member 2 may have a thickness that changes toward the other end of each. .. By reducing the thickness from the connecting portion side ends 4 and 5 toward the other ends of each, it is possible to file even the finest parts of members having various shapes. On the other hand, if the thickness is increased from the connecting portion side end portions 4 and 5 toward the other end portions of each, it becomes easier to file the member on the large surface.

図1の第1張架部材1及び第2張架部材2の長手方向の長さは、第1張架部材1の方が長くなるように設定されているが、何れかが長くないように設定しても良く、略同じ長さに設定しても良い。第2張架部材2を短くなるように設定すると、使用者が連結部3を抑えるように把持することができ、研磨具100の固定が連結部3で解除されることはない。また、第1張架部材1と第2張架部材2を同じ程度の長さに設定すると、連結部側端部4,5から厚みをそれぞれ、薄く、厚くなるように構成することができ、色々な部材の面に研磨することができるため使用者にとって利便性が向上する。 The length of the first tension member 1 and the second tension member 2 in FIG. 1 in the longitudinal direction is set so that the first tension member 1 is longer, but one of them is not longer. It may be set, or it may be set to substantially the same length. When the second tension member 2 is set to be short, the user can grip the connecting portion 3 so as to hold it down, and the fixing of the polishing tool 100 is not released by the connecting portion 3. Further, if the first tension member 1 and the second tension member 2 are set to have the same length, the thickness can be made thinner and thicker from the connecting portion side end portions 4 and 5, respectively. Since the surface of various members can be polished, the convenience for the user is improved.

図2(a)に示されているように、研磨具100を研磨ベルト50に装着する際には、研磨具100を第1張架部材1と第2張架部材2の連結部3において屈曲させた状態にして研磨ベルト50の内方面に入れる。その後、図2(b)に示されているように、研磨具100を連結部3で回動させて屈曲状態から研磨具100の側面が一体形状になるようにすると、研磨部100の側面側は略一体の平面となり、研磨ベルト50の内方面に研磨部100の側面側が密着する。さらに、研磨具100の上面10及び下面20も略一体の平面となることから、研磨具100が研磨ベルト50に密着するとともに使用者の手にフィットするのでヤスリとして使い易いものとなる。研磨具100は、両端を下方向に向ける形で押し込むと研磨ベルト50に装着し易い構成となっている。本発明で利用する研磨ベルト50は、研磨作用面を外方に向けたものを使用する。 As shown in FIG. 2A, when the polishing tool 100 is attached to the polishing belt 50, the polishing tool 100 is bent at the connecting portion 3 of the first tensioning member 1 and the second tensioning member 2. Put it in the inside of the polishing belt 50 in the state of being left. After that, as shown in FIG. 2B, when the polishing tool 100 is rotated by the connecting portion 3 so that the side surface of the polishing tool 100 becomes an integral shape from the bent state, the side surface side of the polishing portion 100 is formed. Is a substantially integral flat surface, and the side surface side of the polishing portion 100 is in close contact with the inner surface of the polishing belt 50. Further, since the upper surface 10 and the lower surface 20 of the polishing tool 100 are also substantially integrated flat surfaces, the polishing tool 100 is in close contact with the polishing belt 50 and fits in the user's hand, so that it is easy to use as a file. The polishing tool 100 has a structure that can be easily attached to the polishing belt 50 by pushing the polishing tool 100 so that both ends face downward. The polishing belt 50 used in the present invention uses a polishing working surface facing outward.

本発明の研磨具の材料は、金属製であっても、樹脂製であっても、木製であってもよいく、研磨の対象となる部材に合わせて材料を選択すればよいが、好ましくは、金属製である。 The material of the polishing tool of the present invention may be made of metal, resin, or wood, and the material may be selected according to the member to be polished, but it is preferable. , Made of metal.
