In the present embodiment, the rotating tool insertion portion 91 is formed of a concave groove, but may be a through hole and is not particularly limited.

そして、挿通部８が第一被挿通部２１及び第二被挿通部５１に挿通可能となると共に、基部９が第一被挿通部２１及び第二被挿通部５１に挿通不可となるように形成されるもので、以下、第一被挿通部２１及び第二被挿通部５１について説明する。 The insertion portion 8 can be inserted into the first insertion portion 21 and the second insertion portion 51, and the base portion 9 can be inserted into the first insertion portion 21 and the second insertion portion 51. The first insertion part 21 and the second insertion part 51 will be described below.

第一被挿通部２１は、図２に示すように、軸部８１が挿通される第一軸部被挿通部２２と、第一軸部被挿通部２２からその周方向の一部に連通して基部側腕部８２及び先端側腕部８３が挿通される第一腕部被挿通部２３と、からなる。本実施形態では、断面が略正多角形状をした軸部８１と略同形状で若干大きい第一軸部被挿通部２２と、軸部８１の先端部から突設される一対の先端側腕部８３と略同形状で若干大きい第一腕部被挿通部２３と、からなる。第一腕部被挿通部２３の幅は、軸部８１の中心を通る幅の最小長さよりも短く形成してあるため、軸部８１は挿通不可となっている。軸部８１は、第一軸部被挿通部２２の部分のみ挿通可能となっている。また、挿通部８は、第一被挿通部２１に対して所定の位置及び向きのみ挿通可能となる。すなわち、軸部８１が第一軸部被挿通部２２に位置し且つ、先端側腕部８３及び基部側腕部８２が第一腕部被挿通部２３と一致する向き（位置）となる状態でのみ挿通可能となる。従って、軸部８１が第一軸部被挿通部２２に位置していても前記所定の向きから回転して基部側腕部８２が第一腕部被挿通部２３に位置しなければ挿通不可となる。このように、第一部材本体２の第一軸部被挿通部２２の周囲の第一腕部被挿通部２３以外の部分が、基部側腕部８２の挿通を阻止する第一係止部２４となる。 As shown in FIG. 2, the first inserted portion 21 communicates with the first shaft portion inserted portion 22 through which the shaft portion 81 is inserted, and a part in the circumferential direction from the first shaft portion inserted portion 22. The first arm portion insertion portion 23 into which the base side arm portion 82 and the distal end side arm portion 83 are inserted. In the present embodiment, the first shaft insertion portion 22 that is substantially the same shape and slightly larger in cross section than the shaft portion 81 having a substantially regular polygonal shape, and a pair of distal arm portions projecting from the distal end portion of the shaft portion 81 83, and a first arm portion insertion portion 23 that is substantially the same shape and slightly larger. Since the width of the first arm portion insertion portion 23 is shorter than the minimum length of the width passing through the center of the shaft portion 81, the shaft portion 81 cannot be inserted. The shaft portion 81 can be inserted only through the first shaft portion insertion portion 22. Further, the insertion part 8 can be inserted through the first insertion part 21 only at a predetermined position and orientation. That is, in a state in which the shaft portion 81 is positioned at the first shaft portion insertion portion 22 and the distal arm portion 83 and the base side arm portion 82 are in an orientation (position) that matches the first arm portion insertion portion 23. Only insertion is possible. Therefore, even if the shaft portion 81 is positioned at the first shaft portion insertion portion 22, it cannot be inserted unless the base side arm portion 82 is positioned at the first arm portion insertion portion 23 by rotating from the predetermined direction. Become. In this way, the first locking portion 24 that prevents the base side arm portion 82 from being inserted by a portion other than the first arm portion inserted portion 23 around the first shaft portion inserted portion 22 of the first member body 2. It becomes.

この第一被挿通部２１は、第一腕部被挿通部２３の第一軸部被挿通部２２からの連通方向が、該第一被挿通部２１が形成された第一部材本体２の面の長辺に対して０°〜９０°の範囲内の傾斜した角度を為すように形成される。 The first insertion portion 21 is configured such that the communication direction of the first arm portion insertion portion 23 from the first shaft portion insertion portion 22 is the surface of the first member body 2 on which the first insertion portion 21 is formed. It is formed so as to form an inclined angle within a range of 0 ° to 90 ° with respect to the long side of the plate.

この第一被挿通部２１には、第一部材本体２の外側から挿通部８が上記所定の位置及び向きの状態で挿通され、先端側腕部８３及び基部側腕部８２が第一部材本体２の第一被挿通部２１が形成された壁部２５を挿通して第一部材本体２の内部に挿入されると共に、基部９が第一部材本体２の第一被挿通部２１の周辺の外面２６に当接される。そして、基部９が回転することで軸部８１と先端側腕部８３及び基部側腕部８２が回転し、基部側腕部８２が第一腕部被挿通部２３からずれた位置に移動し、軸部８１及び基部側腕部８２が第一被挿通部２１から抜けなくなる。 The first insertion portion 21 is inserted with the insertion portion 8 from the outside of the first member main body 2 in the state of the predetermined position and orientation, and the distal side arm portion 83 and the base side arm portion 82 are the first member main body. 2 is inserted into the first member main body 2 through the wall portion 25 in which the first inserted portion 21 is formed, and the base 9 is located around the first inserted portion 21 of the first member main body 2. It abuts on the outer surface 26. Then, by rotating the base portion 9, the shaft portion 81, the distal end side arm portion 83 and the base side arm portion 82 rotate, and the base side arm portion 82 moves to a position shifted from the first arm portion insertion portion 23, The shaft part 81 and the base side arm part 82 cannot be removed from the first insertion part 21.

そして、第一軸部被挿通部２２に挿通された軸部８１と先端側腕部８３及び基部側腕部８２が第一の所定の角度（本実施形態では約４５°）回転すると、仮保持手段１１により、軸部８１と先端側腕部８３及び基部側腕部８２の回転が抑制され回転状態が仮保持される。仮保持手段１１は、本実施形態では、基部側腕部８２と、第一部材本体２の第一軸部被挿通部２２の周辺の内面に内方に向けて突設される係止凸部２７と、で構成される。第一軸部被挿通部２２に挿通された軸部８１と先端側腕部８３及び基部側腕部８２が前記第一の所定の角度回転した状態で、基部側腕部８２の回転方向両側に係止凸部２７が位置するように形成される。第一軸部被挿通部２２に挿通された軸部８１と先端側腕部８３及び基部側腕部８２が前記第一の所定の角度回転する前に、基部側腕部８２が一方の係止凸部２７ａを乗り上げ、前記第一の所定の角度回転する際に基部側腕部８２が一方の係止凸部２７ａを乗り越え、一方の係止凸部２７ａと他方の係止凸部２７ｂとで基部側腕部８２が挟持される。仮保持された状態から更に回転すると、基部側腕部８２が他方の係止凸部２７ｂを乗り越えて回転の抑制がなくなり、仮保持されなくなる。 Then, when the shaft portion 81 inserted through the first shaft portion insertion portion 22 and the distal end side arm portion 83 and the base side arm portion 82 rotate at a first predetermined angle (about 45 ° in the present embodiment), temporary holding is performed. By means 11, rotation of the shaft portion 81, the distal side arm portion 83, and the base side arm portion 82 is suppressed, and the rotation state is temporarily held. In the present embodiment, the temporary holding means 11 is a locking protrusion that protrudes inwardly on the inner surface of the base side arm portion 82 and the periphery of the first shaft portion insertion portion 22 of the first member body 2. 27. The shaft portion 81 inserted through the first shaft portion insertion portion 22, the distal end side arm portion 83, and the base side arm portion 82 are rotated on both sides in the rotational direction of the base side arm portion 82 with the first predetermined angle rotated. It forms so that the latching convex part 27 may be located. Before the shaft portion 81 inserted through the first shaft portion insertion portion 22, the distal end side arm portion 83, and the base side arm portion 82 rotate at the first predetermined angle, the base side arm portion 82 is locked to one side. When riding on the convex portion 27a and rotating at the first predetermined angle, the base side arm portion 82 gets over one locking convex portion 27a, and one locking convex portion 27a and the other locking convex portion 27b The base side arm portion 82 is clamped. When further rotating from the temporarily held state, the base side arm portion 82 gets over the other locking convex portion 27b, and the rotation is not restrained and is not temporarily held.

第二被挿通部５１は、図３に示すように、第一被挿通部２１と略同じで、軸部８１が挿通される第二軸部被挿通部５２と、第二軸部被挿通部５２からその周方向の一部に連通して先端側腕部８３が挿通される第二腕部被挿通部５３と、からなる。本実施形態では、断面が略正多角形状をした軸部８１と略同形状で若干大きい第二軸部被挿通部５２と、軸部８１の先端部から突設される一対の先端側腕部８３と略同形状で若干大きい第二腕部被挿通部５３と、からなる。第二腕部被挿通部５３の幅は、軸部８１の中心を通る幅の最小長さよりも短く形成してあるため、軸部８１は挿通不可となっている。軸部８１は、第二軸部被挿通部５２の部分のみ挿通可能となっている。また、挿通部８は、第二被挿通部５１に対して所定の位置及び向きのみ挿通可能となる。すなわち、軸部８１が第二軸部被挿通部５２に位置し且つ、先端側腕部８３が第二腕部被挿通部５３と一致する向き（位置）となる状態でのみ挿通可能となる。従って、軸部８１が第二軸部被挿通部５２に位置していても前記所定の向きから回転して先端側腕部８３が第二腕部被挿通部５３に位置しなければ挿通不可となる。このように、第二部材本体５の第二軸部被挿通部５２の周囲の第二腕部被挿通部５３以外の部分が、先端側腕部８３の挿通を阻止する第二係止部５４となる。 As shown in FIG. 3, the second inserted portion 51 is substantially the same as the first inserted portion 21, and the second shaft portion inserted portion 52 through which the shaft portion 81 is inserted and the second shaft portion inserted portion. 52, and a second arm portion insertion portion 53 into which the distal arm portion 83 is inserted in communication with a part in the circumferential direction. In the present embodiment, a second shaft portion insertion portion 52 that is substantially the same shape and slightly larger in cross section than the shaft portion 81 having a substantially regular polygonal shape, and a pair of tip side arm portions that protrude from the tip portion of the shaft portion 81. 83 and a second arm portion insertion portion 53 that is substantially the same shape and slightly larger. Since the width of the second arm portion insertion portion 53 is shorter than the minimum length of the width passing through the center of the shaft portion 81, the shaft portion 81 cannot be inserted. The shaft portion 81 can be inserted only through the second shaft portion insertion portion 52. Further, the insertion part 8 can be inserted only into the second insertion part 51 in a predetermined position and direction. That is, the insertion can be performed only in a state where the shaft portion 81 is positioned at the second shaft portion insertion portion 52 and the distal end side arm portion 83 is in a direction (position) coinciding with the second arm portion insertion portion 53. Therefore, even if the shaft portion 81 is positioned at the second shaft portion insertion portion 52, it cannot be inserted unless it rotates from the predetermined direction and the distal arm portion 83 is positioned at the second arm portion insertion portion 53. Become. In this way, the second locking portion 54 that prevents the distal arm portion 83 from being inserted by a portion other than the second arm portion insertion portion 53 around the second shaft portion insertion portion 52 of the second member body 5. It becomes.

この第二被挿通部５１は、第二腕部被挿通部５３の第二軸部被挿通部５２からの連通方向が、第二部材本体５の長辺と略平行となるように形成される。 The second inserted portion 51 is formed such that the communication direction of the second arm portion inserted portion 53 from the second shaft portion inserted portion 52 is substantially parallel to the long side of the second member body 5. .

この第二被挿通部５１には、第二部材本体５の外側から挿通部８が上記所定の位置及び向きの状態（先端側腕部８３及び基部側腕部８２が前記第一の所定の角度回転した状態）で挿通され、先端側腕部８３及び基部側腕部８２が第二部材本体５を挿通する。そして、基部９が回転することで軸部８１と先端側腕部８３及び基部側腕部８２が回転し、基部側腕部８２が第二腕部被挿通部５３からずれた位置に移動し、軸部８１及び基部側腕部８２が第二被挿通部５１から抜けなくなる。 In the second inserted portion 51, the insertion portion 8 is in the predetermined position and orientation from the outside of the second member main body 5 (the distal side arm portion 83 and the base side arm portion 82 are in the first predetermined angle). The distal end side arm portion 83 and the base side arm portion 82 are inserted through the second member main body 5. Then, by rotating the base portion 9, the shaft portion 81, the distal end side arm portion 83 and the base side arm portion 82 rotate, and the base side arm portion 82 moves to a position shifted from the second arm portion insertion portion 53, The shaft portion 81 and the base side arm portion 82 cannot be removed from the second inserted portion 51.

そして、第二軸部被挿通部５２に挿通された軸部８１と先端側腕部８３及び基部側腕部８２が第二の所定の角度（本実施形態では約９０°）回転すると、保持手段１２により、軸部８１と先端側腕部８３及び基部側腕部８２の回転が規制され回転状態が保持される。保持手段１２は、本実施形態では、先端側腕部８３と、第二部材本体５の第二軸部被挿通部５２の周辺の内面に第二軸部被挿通部５２の軸方向に向けて突設される係止凸部５５と、第二軸部被挿通部５２の周辺の前記係止凸部５５と若干の間隔をあけて形成される規制部５６と、で構成される。 When the shaft portion 81 inserted through the second shaft portion insertion portion 52, the distal end side arm portion 83, and the base side arm portion 82 are rotated at a second predetermined angle (about 90 ° in the present embodiment), the holding means 12, the rotation of the shaft portion 81, the distal-side arm portion 83, and the base-side arm portion 82 is restricted, and the rotation state is maintained. In the present embodiment, the holding means 12 is directed to the distal side arm portion 83 and the inner surface around the second shaft portion insertion portion 52 of the second member body 5 in the axial direction of the second shaft portion insertion portion 52. The projecting locking projection 55 and the locking projection 55 around the second shaft portion insertion portion 52 and a regulating portion 56 formed with a slight gap therebetween.

第二軸部被挿通部５２に挿通された軸部８１と先端側腕部８３及び基部側腕部８２が前記第二の所定の角度回転する際に先端側腕部８３が係止凸部５５を乗り越え、規制部５６により先端側腕部８３のそれ以上の移動が規制される。係止凸部５５と規制部５６とで基部側腕部８２が挟持され、連結部材７が保持される。 When the shaft portion 81 inserted through the second shaft portion insertion portion 52, the distal arm portion 83, and the base arm portion 82 rotate at the second predetermined angle, the distal arm portion 83 is engaged with the locking projection 55. The restriction part 56 restricts further movement of the distal end side arm part 83. The base side arm portion 82 is sandwiched between the locking convex portion 55 and the restricting portion 56, and the connecting member 7 is held.

上記本発明の締結具は、第一部材本体２の第一被挿通部２１に外側から連結部材７の挿通部８が第一部材本体２に対して所定の位置及び向きで挿通される。この時、第一被埋設部３と第二被埋設部６は、その軸方向が直交する。 In the fastener of the present invention, the insertion portion 8 of the connecting member 7 is inserted from the outside into the first insertion portion 21 of the first member main body 2 at a predetermined position and orientation with respect to the first member main body 2. At this time, the axial direction of the first embedded portion 3 and the second embedded portion 6 is orthogonal.

そして、連結部材７の基部９が回転することで、第一係止部２４により軸部８１及び基部側腕部８２が第一被挿通部２１から抜けなくなると共に、第一の所定の角度回転すると、仮保持手段１１により仮保持される。次に第一部材本体２に第二部材本体５を嵌め込むことで、挿通部８が第二部材本体５の第二被挿通部５１に挿通され、基部９が回転することで、第二係止部５４により基部側腕部８２が第二被挿通部５１から抜けなくなると共に、第二の所定の角度回転すると、保持手段１２により保持され、締結が完了する。 When the base portion 9 of the connecting member 7 is rotated, the shaft portion 81 and the base-side arm portion 82 are not removed from the first insertion portion 21 by the first locking portion 24 and are rotated by a first predetermined angle. Temporarily held by the temporary holding means 11. Next, by inserting the second member main body 5 into the first member main body 2, the insertion portion 8 is inserted into the second insertion portion 51 of the second member main body 5, and the base portion 9 is rotated. When the base side arm portion 82 cannot be removed from the second inserted portion 51 by the stop portion 54 and is rotated by a second predetermined angle, the holding means 12 holds and the fastening is completed.

上述した締結具は、組み立て作業時に、作業者がビスを被締結部材に螺着する必要がなく、コイン等の回転具により連結部材７を１回転未満回転させるだけでよいため、従来のビスを螺着する連結具と比べて、作業性が良いものである。また、第一部材１、第二部材４、連結部材７の３ピースで構成されるため、部品点数が少なく取り扱いが容易である。 The above-described fastener does not require an operator to screw a screw into a member to be fastened at the time of assembly work, and it is only necessary to rotate the connecting member 7 by less than one rotation with a rotating tool such as a coin. Compared with a screwed connector, the workability is good. Moreover, since it is comprised by 3 pieces, the 1st member 1, the 2nd member 4, and the connection member 7, there are few number of parts and handling is easy.

また、仮保持手段１１により連結部材７が第一部材１に仮保持されるため、作業者は、第二部材４を取り付ける際に連結部材７を、抜け落ちたり、回転したりしないように支持する必要がなく、この点でも作業性が良いものである。 Further, since the connecting member 7 is temporarily held by the first member 1 by the temporary holding means 11, the operator supports the connecting member 7 so as not to drop off or rotate when the second member 4 is attached. There is no need, and the workability is also good in this respect.

また、第二部材本体５が、第一部材本体２の開口２０と略同形状で若干小さく形成してあるため、第一部材本体２の開口２０に第二部材本体５が所定の向きでガタつきなく嵌入され、第一被挿通部２１と第二被挿通部５１とが自動的に所定の向きに重ね合わせられる。これにより、作業者が自分で第一被挿通部２１と第二被挿通部５１とを所定の向きに重ね合わせる必要がなく、この点でも作業性が良いものである。 In addition, since the second member main body 5 is substantially the same shape as the opening 20 of the first member main body 2 and is formed slightly smaller, the second member main body 5 has a backlash in a predetermined direction in the opening 20 of the first member main body 2. The first insertion part 21 and the second insertion part 51 are automatically overlapped in a predetermined direction. Thereby, it is not necessary for the operator to superimpose the first inserted part 21 and the second inserted part 51 in a predetermined direction, and the workability is also good in this respect.

また、第一部材１と連結部材７の色調が異なることで、第二部材４が締結される際に挿通部８が識別し易くなり、この点でも作業性が良くなるものである。第一部材１と連結部材７の色調は特に限定されないが、例えば第一部材１が白（又は黒）、連結部材７が黒（又は白）であれば、特に識別がし易くなる。 Further, since the first member 1 and the connecting member 7 are different in color tone, the insertion portion 8 can be easily identified when the second member 4 is fastened, and workability is improved in this respect as well. The color tone of the first member 1 and the connecting member 7 is not particularly limited. For example, if the first member 1 is white (or black) and the connecting member 7 is black (or white), it is particularly easy to identify.
