Description

本発明は、連結具に関する。たとえば、バック類において、ベルトや紐の着脱用として用いられる連結具に関する。   The present invention relates to a connector. For example, the present invention relates to a connector used for attaching or detaching a belt or string in bags.

たとえば、バック類において、ベルトや紐を簡易に着脱するための金具として、なす環が利用されている。
通常、なす環は、一端がテープなどに固定され、他端にベルトや紐などの連結部を着脱可能なフック部を備えた構造であるが、中には、両端部にフック部を備えた連結なす環も提案されている（特許文献１参照）。 For example, in a bag, a ring formed as a metal fitting for easily attaching and detaching a belt or a string is used.
Normally, an annulus has a structure in which one end is fixed to a tape or the like, and a hook part to which a connecting part such as a belt or a string can be attached and detached at the other end. Linked rings have also been proposed (see Patent Document 1).

この連結なす環は、フック部の開口に閉止杆を常時閉塞するように付勢した一対のなす環の基部に軸をそれぞれ突出させ、この一対のなす環の軸をそれぞれ接続輪環の両端から貫挿し、接続輪環に対してなす環が軸を中心として回動可能に連結された構造である。
従って、両側になす環をもっているため、一方を任意の場所に連結し、他方をベルトや紐の連結部の着脱用として利用することができる。 The connecting ring is formed by projecting shafts to the bases of a pair of ring rings that are urged so as to always close the closing rods at the opening of the hook part, and the shafts of the pair of ring rings are respectively connected from both ends of the connection ring. It is a structure in which a ring formed through the connecting ring is connected so as to be rotatable about an axis.
Accordingly, since the ring is formed on both sides, one can be connected to an arbitrary place, and the other can be used for attaching and detaching the connecting portion of the belt or string.

しかし、特許文献１に記載の連結なす環は、フック部の開口に閉止杆を常時閉塞するように付勢した一対のなす環の基部に軸をそれぞれ突出させ、この一対のなす環の軸を向かい合わせにして、それぞれ接続輪環に貫挿させた構造であるため、全長が長くなる。
しかも、フック部にベルトや紐、あるいは、これらの先端に取り付けた連結材を引っ掛けて連結する構造のため、ベルトや紐、あるいは、連結材がフック部内でがたついたり、あるいは、回りやすく、安定した状態で連結できない。 However, in the connecting ring described in Patent Document 1, the shafts are protruded from the bases of a pair of ring rings that are urged so as to always close the closing rods at the openings of the hook parts. Since the structure is made to face each other and inserted through the connecting ring, the total length becomes longer.
Moreover, because of the structure that hooks and connects the belt or string to the hook part, or the connecting material attached to these tips, the belt or string or the connecting material rattles in the hook part, or it is easy to turn, Cannot be connected in a stable state.

本発明の目的は、このような課題を解決し、全体としてコンパクトに構成でき、かつ、ベルトや紐あるいは連結材を安定して連結できる連結具を提供することにある。   An object of the present invention is to solve such problems, and to provide a connector that can be configured compactly as a whole and that can stably connect a belt, a string, or a connecting material.

本発明の連結具は、一対の保持具と、前記一対の保持具を連結し、かつ、この連結方向軸線を中心に前記各保持具を回動可能に支持する連結部材とを備え、前記連結部材は、両端部に前記一対の保持具を回動可能に支持した連結軸によって構成され、前記一対の保持具のうち少なくとも一方の保持具は、第１挟持板と、この第１挟持板に対して起伏可能に支持された第２挟持板と、前記第１挟持板および前記第２挟持板の互いに対向する面のいずれか一方に設けられた突起状の係合部と、前記第１挟持板および前記第２挟持板の互いに対向する面のいずれか他方に設けられ前記係合部と係合する被係合部とを含み、前記係合部は、前記第１挟持板および前記第２挟持板の互いに対向する面のいずれか一方に設けられた突起の先端に、突起の軸と直交する方向の寸法が大きくなった頭部を有し、前記被係合部は、前記第１挟持板および前記第２挟持板のいずれか他方にスライド可能に設けられた少なくとも１つのスライド部材を有し、前記スライド部材は、スライド方向の一方向へ付勢され、かつ、付勢された状態において前記係合部の頭部が入り込み、頭部と係合する開口を有する、ことを特徴とする。 The coupling tool of the present invention includes a pair of holding tools, and a coupling member that couples the pair of holding tools and rotatably supports the holding tools around the coupling direction axis. The member is constituted by a connecting shaft that rotatably supports the pair of holders at both ends, and at least one of the pair of holders is provided with a first holding plate and the first holding plate. A second sandwiching plate that is supported in a undulating manner, a projecting engagement portion provided on one of the opposing surfaces of the first sandwiching plate and the second sandwiching plate, and the first sandwiching plate. look including a engaged portion to be engaged with the engagement portion to each other is provided to the other of the opposing faces of the plate and the second clamping plate, said engaging portion, said first clamping plate and the second 2 At the tip of the protrusion provided on one of the opposing surfaces of the sandwiching plate, The head has an enlarged dimension in the orthogonal direction, and the engaged portion includes at least one slide member slidably provided on one of the first sandwiching plate and the second sandwiching plate. The slide member is biased in one direction of the slide direction, and has an opening that engages with the head when the head of the engaging portion enters in the biased state. To do.

この構成によれば、連結するベルトや紐、あるいは、これらの先端に取り付けた連結材の係合孔を係合部に差し込んだのち、第２挟持板を第１挟持板に対して伏した状態にすると、係合部が被係合部に係合され、第１挟持板と第２挟持板が係合される。
この状態では、ベルトや紐、あるいは、連結材は、第１挟持板と第２挟持板との間に挟まれているため、これらの間での動きが規制される。従って、ベルトや紐あるいは連結材ががたついたり、回転するのを防止できる。
また、一対の保持具のうち少なくとも一方の保持具は、第１挟持板に対して第２挟持板が起伏する構造であるため、全長も短くできる。つまり、従来の連結なす環のように、細長いフック部の構成としなくてもよいから、全長も短くできる。 According to this structure, after inserting the engagement hole of the belt or string to connect, or the connection material attached to these front-end | tips into an engagement part, the 2nd clamping board is in the state where it fell down with respect to the 1st clamping board Then, the engaging portion is engaged with the engaged portion, and the first holding plate and the second holding plate are engaged.
In this state, since the belt, the string, or the connecting material is sandwiched between the first sandwiching plate and the second sandwiching plate, the movement between them is restricted. Therefore, it is possible to prevent the belt, the string or the connecting material from rattling or rotating.
In addition, since at least one of the pair of holders has a structure in which the second holding plate is raised and lowered with respect to the first holding plate, the entire length can be shortened. That is, since it is not necessary to have a long and narrow hook portion as in the case of a conventional linked ring, the overall length can be shortened.

また、連結軸の両端部によって、一対の保持具を回動可能に支持したので、連結部材の構成を簡易にかつ安価に構成できる。とくに、連結軸によって、一対の保持具が連結方向軸線を中心に回動可能に連結されているので、これらの保持具にベルトや紐などを連結する場合、ベルトや紐は捩れたりしやすいが、これらの捩れにも対応して捩れがない状態で連結できる。 In addition, since the pair of holders are rotatably supported by the both ends of the connecting shaft, the structure of the connecting member can be configured easily and inexpensively. In particular, since the pair of holders are connected to each other by the connecting shaft so as to be rotatable about the connecting direction axis, when the belts or strings are connected to these holders, the belts or strings are likely to be twisted. Corresponding to these twists, they can be connected without twisting.

更に、前記係合部は、前記第１挟持板および前記第２挟持板の互いに対向する面のいずれか一方に設けられた突起の先端に、突起の軸と直交する方向の寸法が大きくなった頭部を有し、前記被係合部は、前記第１挟持板および前記第２挟持板のいずれか他方にスライド可能に設けられた少なくとも１つのスライド部材を有し、前記スライド部材は、スライド方向の一方向へ付勢され、かつ、付勢された状態において前記係合部の頭部が入り込み、頭部と係合する開口を有する。 Further, the engaging portion has a dimension in the direction perpendicular to the axis of the protrusion at the tip of the protrusion provided on one of the opposing surfaces of the first and second clamping plates. A head portion, and the engaged portion has at least one slide member slidably provided on one of the first sandwiching plate and the second sandwiching plate, and the slide member is a slide It is urged in the direction of the one direction, and enters said engaging portion of the head in the energized state, that having a opening that engages the head.

従って、スライド部材の開口が係合部と一致した状態、または、僅かずれた状態において、第２挟持板を第１挟持板に対して伏した姿勢に回動すると、係合部が開口に入り込む。係合部の頭部が開口を超えた位置まで入り込むと、スライド部材が付勢方向へスライドされる。すると、開口と係合部とが係合される。つまり、係合部の頭部が開口に引っ掛かり、第２挟持板が起立するのが規制されるから、簡単な構造で、第１挟持板と第２挟持板とを係合させることができる。 Accordingly, when the opening of the slide member coincides with the engaging portion or is slightly displaced, the engaging portion enters the opening when the second holding plate is rotated to a position inclined with respect to the first holding plate. . When the head of the engaging portion enters the position beyond the opening, the slide member is slid in the biasing direction. Then, the opening and the engaging portion are engaged. That is, since the head of the engaging portion is caught in the opening and the second holding plate is prevented from standing up, the first holding plate and the second holding plate can be engaged with each other with a simple structure.

本発明の連結具は、一対の保持具と、前記一対の保持具を連結し、かつ、この連結方向軸線を中心に前記各保持具を回動可能に支持する連結部材とを備え、前記連結部材は、両端部に前記一対の保持具を回動可能に支持した連結軸によって構成され、前記一対の保持具のうち少なくとも一方の保持具は、第１挟持板と、この第１挟持板に対して起伏可能に支持された第２挟持板と、前記第１挟持板および前記第２挟持板の互いに対向する面のいずれか一方に設けられた突起状の係合部と、前記第１挟持板および前記第２挟持板の互いに対向する面のいずれか他方に設けられ前記係合部と係合する被係合部とを含み、前記被係合部は、前記第１挟持板および前記第２挟持板のいずれか他方にスライド可能に設けられた一対のスライド部材を有し、前記一対のスライド部材は、互いに重ね合わされた状態でスライド可能に設けられた一対のスライド片と、この各スライド片に一体形成されこれら一対のスライド片を互いに離間する方向へ付勢する弾性脚片と、前記各スライド片に設けられ前記弾性脚片によって一対のスライド片が互いに離間する方へ付勢された状態において前記第１挟持板および前記第２挟持板のいずれか他方から突出する操作部と、前記各スライド片に設けられ前記弾性脚片によって一対のスライド片が互いに離間する方向へ付勢された状態において前記係合部と係合する挟持部とを有する、ことを特徴とする。 The coupling tool of the present invention includes a pair of holding tools, and a coupling member that couples the pair of holding tools and rotatably supports the holding tools around the coupling direction axis. The member is constituted by a connecting shaft that rotatably supports the pair of holders at both ends, and at least one of the pair of holders is provided with a first holding plate and the first holding plate. A second sandwiching plate that is supported in a undulating manner, a projecting engagement portion provided on one of the opposing surfaces of the first sandwiching plate and the second sandwiching plate, and the first sandwiching plate. An engagement portion provided on one of the opposing surfaces of the plate and the second sandwiching plate and engaged with the engagement portion, wherein the engaged portion includes the first sandwiching plate and the first sandwiching plate. Having a pair of slide members slidably provided on either one of the two clamping plates The pair of slide members includes a pair of slide pieces provided so as to be slidable in a state of being overlapped with each other, and elastic leg pieces integrally formed with the slide pieces and biasing the pair of slide pieces in a direction away from each other. And an operating portion that is provided on each of the slide pieces and protrudes from one of the first holding plate and the second holding plate in a state where the pair of slide pieces are biased toward each other by the elastic leg pieces. And a sandwiching portion that engages with the engaging portion in a state in which the pair of slide pieces are urged away from each other by the elastic leg pieces provided on the slide pieces .

この構成によれば、一対のスライド片の操作部を操作して、スライド片を互いに接近する方向へスライドさせると、スライド片の挟持部が離間される。すると、これに係合されていた係合部が解除されるから、この状態で第２挟持板を第１挟持板に対して起立させたのち、係合部からベルトや紐、あるいは、これらの先端に取り付けた連結材を外せば、連結具からベルトや紐、あるいは、これらの先端に取り付けた連結材を外すことができる。   According to this configuration, when the operation parts of the pair of slide pieces are operated and the slide pieces are slid in the direction approaching each other, the holding parts of the slide pieces are separated. Then, since the engaging part engaged with this is cancelled | released, after raising a 2nd clamping board with respect to a 1st clamping board in this state, a belt, a string, or these from an engaging part If the connecting material attached to the tip is removed, the belt, the string, or the connecting material attached to the tip can be removed from the connector.

本発明の連結具において、前記第２挟持板は、前記第１挟持板に前記連結方向軸線に対して略直交する支軸を支点として起伏可能に支持されている、ことが好ましい。
この構成によれば、第２挟持板は、第１挟持板に連結方向軸線に対して略直交する支軸を支点として起伏可能に支持されているから、第２挟持板を第１挟持板に対して起伏動作させても、保持具が連結方向軸線を中心に回動するのを防止できる。つまり、第２挟持板の起伏動作と一対の保持具の回動動作とが、直交しているから、一方の動作によって他方が動作するのを防止できる。 In the connector according to the present invention, it is preferable that the second sandwiching plate is supported by the first sandwiching plate so as to be raised and lowered with a support shaft that is substantially perpendicular to the connection direction axis as a fulcrum.
According to this configuration, the second clamping plate is supported by the first clamping plate so that it can be raised and lowered with a support shaft that is substantially orthogonal to the connection direction axis as a fulcrum. Therefore, the second clamping plate is used as the first clamping plate. Even if the undulation operation is performed, the holder can be prevented from rotating around the connecting direction axis. That is, since the raising / lowering operation of the second clamping plate and the rotating operation of the pair of holders are orthogonal to each other, it is possible to prevent the other from operating due to one operation.

本発明の連結具において、前記一対の保持具のうち他方の保持具は、ベルトを連結可能なリング状に形成されている、ことが好ましい。
例えば、他方の保持具は、幅方向中央部が一方の保持具に回動可能に連結された枠体と、この枠体の内部に設けられベルトが挿通して連結されるベルト挿通孔とを備えるリング状に形成された構成が好ましい。このようにすれば、ベルト挿通孔の幅寸法が異なる保持具を数種類用意しておけば、簡単な構成で幅寸法の異なるベルトにも適用できる。 In the connector of the present invention, it is preferable that the other holder of the pair of holders is formed in a ring shape capable of connecting the belt.
For example, the other holding tool includes a frame body having a central portion in the width direction rotatably connected to the one holding tool, and a belt insertion hole provided inside the frame body and through which a belt is inserted and connected. The structure formed in the ring shape provided is preferable. If it does in this way, if it prepares several types of holders from which the width dimension of a belt penetration hole differs, it can apply also to a belt from which a width dimension differs by simple structure.

これら一対のスライド部材４１Ａ，４１Ｂは、同じ形状に形成され、一方が他方に対して裏返しされ、かつ、重ね合わせた状態で使用される。各スライド部材４１Ａ，４１Ｂは、長方形板状のスライド片４２と、このスライド片４２の長手方向に沿った側面からスライド片４２の挿入方向に対して逆方向へ屈曲して形成され収容部２３の係合溝２５に係合されるストッパ片４７と、スライド片４２の長手方向一端から延長して形成された弾性脚片４８とを有する。 The engaged portion 40 has a pair of slide members 41 </ b> A and 41 </ b> B that are inserted from both side surface openings (openings of the accommodating portion 23) of the second sandwiching plate 20 and are slidably provided in the accommodating portion 23.
The pair of slide members 41A and 41B are formed in the same shape, and one is turned upside down with respect to the other, and is used in a superposed state. Each of the slide members 41A and 41B is formed by bending a rectangular plate-like slide piece 42 and a side surface along the longitudinal direction of the slide piece 42 in a direction opposite to the insertion direction of the slide piece 42. A stopper piece 47 engaged with the engaging groove 25 and an elastic leg piece 48 formed extending from one end in the longitudinal direction of the slide piece 42 are provided.

スライド片４２には、内部に矩形状の開口４３が形成されているとともに、挿入方向先端（弾性脚片４８が延長する方向端）とは反対の挿入方向後端部裏面側に肉厚が他より厚い段部４４が形成されている。開口４３の長手方向開口縁のうち、挿入方向先端縁には、第１挟持板１０の係合部３０を挟持する挟持部４５が形成されている。段部４４の挿入方向後端部には、スライド片４２が互いに離間する方向へ付勢された状態において第２挟持板２０の収容部２３から外部へ突出する操作部４６が形成されている。   The slide piece 42 has a rectangular opening 43 formed therein, and has a wall thickness on the back side in the insertion direction rear end opposite to the insertion direction front end (direction end in which the elastic leg piece 48 extends). A thicker step 44 is formed. Of the opening edge in the longitudinal direction of the opening 43, a clamping part 45 that clamps the engaging part 30 of the first clamping plate 10 is formed at the leading edge in the insertion direction. An operation portion 46 is formed at the rear end portion in the insertion direction of the stepped portion 44 so as to protrude from the housing portion 23 of the second holding plate 20 to the outside in a state where the slide pieces 42 are biased in a direction away from each other.

ストッパ片４７は、スライド片４２の長手方向に沿った側面の略中央位置からスライド片４２の挿入方向に対して逆方向へ屈曲して形成されている。スライド片４２が収容部２３内に挿入されると、ストッパ片４７は、内側へ弾性変形された状態で挿入され、所定位置まで挿入された段階で外側へ弾性復帰して、係合溝２５に係合される。つまり、ストッパ片４７が係合溝２５に係合するため、スライド片４２が収容部２３から脱落するのが防止される。   The stopper piece 47 is formed by bending in a direction opposite to the insertion direction of the slide piece 42 from a substantially central position of the side surface along the longitudinal direction of the slide piece 42. When the slide piece 42 is inserted into the housing portion 23, the stopper piece 47 is inserted in a state of being elastically deformed inward, and when it is inserted to a predetermined position, the stopper piece 47 is elastically returned to the outside and enters the engagement groove 25. Engaged. That is, since the stopper piece 47 engages with the engaging groove 25, the slide piece 42 is prevented from falling off from the accommodating portion 23.

弾性脚片４８は、スライド片４２の挿入方向先端一側から幅方向外側へ向かって延長され、更に、スライド片４２の幅方向他側へ向かって延長されたのち、先端に円柱状の接触子４９を有する。スライド片４２が収容部２３内に挿入された状態において、先端の接触子４９が、相手方のスライド片４２の段部４４に当接される。これにより、弾性脚片４８の弾性力により、一対のスライド部材４１Ａ，４１Ｂが互いに離間する方向へ付勢され、これらスライド部材４１Ａ，４１Ｂの操作部４６が収容部２３から外部へ突出される。   The elastic leg piece 48 extends from the one end in the insertion direction of the slide piece 42 toward the outer side in the width direction, and further extends toward the other side in the width direction of the slide piece 42, and then has a cylindrical contact at the tip. 49. In a state where the slide piece 42 is inserted into the accommodating portion 23, the contact 49 at the tip is brought into contact with the stepped portion 44 of the counterpart slide piece 42. Accordingly, the pair of slide members 41A and 41B are urged away from each other by the elastic force of the elastic leg pieces 48, and the operation portion 46 of the slide members 41A and 41B protrudes from the housing portion 23 to the outside.

（連結部材）
連結部材Ｃは、両端部に一対の保持具Ａ，Ｂを回動可能に支持した連結軸５０によって構成されている。連結軸５０は、軸受壁１２の連結軸挿通孔１３に回動可能に挿通される太さの軸材で、中央にフランジ５１を有し、両端部分にストップリング係止溝５２を有する。従って、連結軸５０の両端部分に各保持具Ａ，Ｂの軸受壁１２に形成された連結軸挿通孔１３を挿通したのち、各連結軸挿通孔１３から突出した連結軸５０のストップリング係止溝５２にストップリング５３を係合すれば、一対の保持具Ａ，Ｂが連結軸５０によって回動可能に連結される。 (Connecting member)
The connecting member C is constituted by a connecting shaft 50 that supports a pair of holders A and B so as to be rotatable at both ends. The connecting shaft 50 is a shaft member having a thickness that is rotatably inserted into the connecting shaft insertion hole 13 of the bearing wall 12, has a flange 51 in the center, and has stop ring locking grooves 52 at both ends. Therefore, after the connecting shaft insertion holes 13 formed in the bearing walls 12 of the holders A and B are inserted into both end portions of the connecting shaft 50, the stop rings of the connecting shafts 50 protruding from the connecting shaft insertion holes 13 are locked. When the stop ring 53 is engaged with the groove 52, the pair of holders A and B are rotatably connected by the connecting shaft 50.

（作用・効果）
ベルト２の先端に取り付けられた連結材３と、ベルト４の先端に取り付けられた連結材５とを連結するには、各保持具Ａ，Ｂに連結材３，５を保持させる。
これには、図８に示すように、第２挟持板２０を第１挟持板１０に対して起立させた状態、つまり、突起１６と軸受壁１２との間に連結材３，５の一部が収容される収容空間を開口した状態とし、この状態において、第１挟持板１０の突起１６に連結材３，５の引掛孔７を挿入したのち、第２挟持板２０を支軸１４を支点として回動し、第１挟持板１０に対して伏した状態とする。 (Action / Effect)
In order to connect the connecting member 3 attached to the tip of the belt 2 and the connecting member 5 attached to the tip of the belt 4, the holding members A and B hold the connecting members 3 and 5.
For this purpose, as shown in FIG. 8, the second sandwiching plate 20 is erected with respect to the first sandwiching plate 10, that is, a part of the connecting members 3, 5 between the protrusion 16 and the bearing wall 12. In this state, after inserting the catching holes 7 of the connecting members 3 and 5 into the protrusions 16 of the first clamping plate 10, the second clamping plate 20 is supported by the support shaft 14 as a fulcrum. It is set as the state which turned down and fell with respect to the 1st clamping board 10. As shown in FIG.

すると、図６および図７に示すように、第２挟持板２０が第１挟持板１０の突起１６の真上に位置し、更に、第２挟持板２０の被係合部４０が第１挟持板１０の突起１６の頭部３２に当接する。つまり、第２挟持板２０の被係合部４０を構成する一対のスライド部材４１Ａ，４１Ｂの挟持部４５が、突起１６の頭部３２に当接し、この頭部３２によってスライド部材４１Ａ，４１Ｂが弾性脚片４８を弾性変形させながら、収容部２３内に挿入される方向へスライドされる（図５の状態）。これにより、スライド部材４１Ａ，４１Ｂの挟持部４５の間隔が拡がるため、突起１６の頭部３２がこれらの挟持部４５を越えて第２挟持板２０の収容部２３内に挿入される。突起１６の頭部３２が挟持部４５を越えると、スライド部材４１Ａ，４１Ｂは、弾性変形されていた弾性脚片４８の復帰力により、元の位置までスライドされる（図４の状態）。   Then, as shown in FIGS. 6 and 7, the second sandwiching plate 20 is positioned directly above the protrusion 16 of the first sandwiching plate 10, and the engaged portion 40 of the second sandwiching plate 20 is first sandwiched. It contacts the head 32 of the protrusion 16 of the plate 10. That is, the sandwiching portions 45 of the pair of slide members 41A and 41B constituting the engaged portion 40 of the second sandwiching plate 20 abut on the head 32 of the protrusion 16, and the slide members 41A and 41B are caused to move by the head 32. While elastically deforming the elastic leg piece 48, the elastic leg piece 48 is slid in the direction to be inserted into the accommodating portion 23 (state of FIG. 5). As a result, the interval between the holding portions 45 of the slide members 41 </ b> A and 41 </ b> B increases, so that the head portion 32 of the protrusion 16 is inserted into the accommodating portion 23 of the second holding plate 20 beyond these holding portions 45. When the head portion 32 of the protrusion 16 exceeds the clamping portion 45, the slide members 41A and 41B are slid to their original positions by the restoring force of the elastic leg pieces 48 that have been elastically deformed (state of FIG. 4).

この状態、つまり、係合部３０が被係合部４０に係合され、第１挟持板１０と第２挟持板２０が係合された状態では、ベルト２，４の先端の連結材３，５は、突起１６に引っ掛けられ、かつ、突起１６より幅広な第１挟持板１０と第２挟持板２０との間に挟まれているため、これらの間での動きが規制される。例えば、連結材３，５が、連結部材Ｃの軸線と同じ方向を中心として回動しようとしても、連結材３，５が第１挟持板１０と第２挟持板２０とに接触するので、第１挟持板１０と第２挟持板２０との間での動きが規制される。
従って、連結材３，５が連結具１に連結された状態において、連結材３，５ががたついたり、回転するのを防止できる。 In this state, that is, in a state where the engaging portion 30 is engaged with the engaged portion 40 and the first holding plate 10 and the second holding plate 20 are engaged, the connecting members 3 at the tips of the belts 2 and 4 are connected. Since 5 is caught by the protrusion 16 and is sandwiched between the first sandwiching plate 10 and the second sandwiching plate 20 which are wider than the projection 16, the movement between them is restricted. For example, even if the connecting members 3 and 5 try to rotate about the same direction as the axis of the connecting member C, the connecting members 3 and 5 come into contact with the first sandwiching plate 10 and the second sandwiching plate 20. The movement between the first clamping plate 10 and the second clamping plate 20 is restricted.
Therefore, it is possible to prevent the connecting members 3 and 5 from rattling or rotating in a state where the connecting members 3 and 5 are connected to the connecting tool 1.

しかも、第２挟持板２０を第１挟持板１０に対して伏した状態では、第２挟持板２０の当接面２７が、係合部３０の頭部３２に当接するため、それ以上、第２挟持板２０が第１挟持板１０に接近するのを防止できる。従って、第１挟持板１０と第２挟持板２０との間隔を一定間隔に維持できる。
ここで、連結材３，５を挟持するとは、図８にも示すように、第１挟持板１０と第２挟持板２０とが対面し、これらの間隔を持った空間に連結材３，５の一部が配置されることで、第１挟持板１０および第２挟持板２０と連結材３，５との間に隙間があることも挟持である。 In addition, in the state where the second clamping plate 20 is lying down with respect to the first clamping plate 10, the contact surface 27 of the second clamping plate 20 comes into contact with the head 32 of the engaging portion 30. It is possible to prevent the two clamping plates 20 from approaching the first clamping plate 10. Therefore, the interval between the first clamping plate 10 and the second clamping plate 20 can be maintained at a constant interval.
Here, as shown in FIG. 8, when the connecting members 3 and 5 are sandwiched, the first sandwiching plate 10 and the second sandwiching plate 20 face each other, and the connecting members 3 and 5 are placed in a space having an interval therebetween. It is also nipping that there is a gap between the first clamping plate 10 and the second clamping plate 20 and the connecting members 3 and 5 due to the arrangement of a part.

また、各保持具Ａ，Ｂは、第１挟持板１０に対して第２挟持板２０が起伏する構造で、ベルトを連結したときに内部に連結部を収容する形をとるため、全長も短くできる。つまり、第１挟持板１０が支軸１４を中心に回動することで、連結材３，５が収容される収容空間が開口される構造であるため、従来の連結なす環のように、細長いフック部の構成としなくてもよいから、全長も短くできる。
また、連結軸５０を介して連結された一対の保持具Ａ，Ｂは、連結軸５０の軸線を中心に回動可能であるため、連結材３，５やベルト２，４の向きを使用状態に応じて最適な向き（姿勢）にした状態で連結することができる。
しかも、連結軸５０の両端部によって、一対の保持具Ａ，Ｂを回動可能に支持したので、連結部材Ｃの構成を簡易にかつ安価に構成できる。 In addition, each of the holding tools A and B has a structure in which the second holding plate 20 is raised and lowered with respect to the first holding plate 10 and has a shape in which the connecting portion is accommodated when the belt is connected, so that the overall length is also short. it can. That is, the first holding plate 10 rotates around the support shaft 14 to open the accommodation space in which the coupling members 3 and 5 are accommodated. Since the hook portion need not be configured, the overall length can be shortened.
In addition, since the pair of holders A and B connected via the connecting shaft 50 can rotate around the axis of the connecting shaft 50, the directions of the connecting members 3 and 5 and the belts 2 and 4 are used. Can be connected in an optimal orientation (posture).
Moreover, since the pair of holders A and B are rotatably supported by the both ends of the connecting shaft 50, the structure of the connecting member C can be configured easily and inexpensively.

また、ベルト２，４の先端に取り付けられた連結材３，５を、各保持具Ａ，Ｂから外すには、スライド部材４１Ａ，４１Ｂの操作部４６を押圧操作して、スライド部材４１Ａ，４１Ｂを収容部２３内に挿入する方向へスライドさせると、スライド部材４１Ａ，４１Ｂの挟持部４５が離間される。
挟持部４５の間隔が係合部３０の頭部３２よりも大きい寸法に離間されると、係合部３０はこれらから解除されるから、この状態で第２挟持板２０を第１挟持板１０に対して起立させたのち、突起１６から連結材３，５を外せば、保持具Ａ，Ｂから連結材３，５を外すことができる。 Further, in order to remove the connecting members 3 and 5 attached to the tips of the belts 2 and 4 from the holders A and B, the operating members 46 of the slide members 41A and 41B are pressed to slide the slide members 41A and 41B. Is slid in the direction of insertion into the accommodating portion 23, the holding portions 45 of the slide members 41A and 41B are separated.
When the interval between the holding portions 45 is separated to a size larger than the head portion 32 of the engaging portion 30, the engaging portion 30 is released from these, and in this state, the second holding plate 20 is moved to the first holding plate 10. If the connecting members 3 and 5 are removed from the protrusions 16 after being raised, the connecting members 3 and 5 can be removed from the holders A and B.

この際、連結材３，５の着脱に際して、第２挟持板２０を第１挟持板１０に対して起伏動作させても、一対の保持具Ａ，Ｂが連結方向軸線を中心に回動するのを防止できる。つまり、第２挟持板２０の起伏動作と一対の保持具Ａ，Ｂの回動動作とが、直交しているから、一方の動作によって他方が動作するのを防止できる。   At this time, when attaching and detaching the connecting members 3 and 5, even if the second holding plate 20 is moved up and down with respect to the first holding plate 10, the pair of holders A and B rotate about the connecting direction axis. Can be prevented. That is, since the raising / lowering operation of the second clamping plate 20 and the rotating operation of the pair of holders A and B are orthogonal to each other, it is possible to prevent one operation from operating the other.

The three belt insertion holes 6A, 6B, 6C having different width dimensions are formed in parallel with each other at predetermined intervals.

（第２変形例）
更に、例えば、図１２に示すように、いわゆる、平カンと称される連結材７０を連結することもできる。連結材７０は、矩形輪状に形成された連結材で、幅方向寸法が連結するベルトの幅寸法に応じて何種類か用意されている。例えば、図１２に示す連結材７１のほかに、これより幅寸法が小さい連結材が用意されている。 (Second modification)
Furthermore, for example, as shown in FIG. 12, a so-called connecting member 70 called a flat can can be connected. The connecting member 70 is a connecting member formed in a rectangular ring shape, and several types are prepared according to the width dimension of the belt to be connected in the width direction. For example, in addition to the connecting material 71 shown in FIG. 12, a connecting material having a smaller width dimension is prepared.

連結材７０を連結具１に連結するに際しては、それぞれに連結材７０の幅方向の孔寸法より僅かに小さい長さ寸法を有する直方体形状のアタッチメント７３を用いて連結する。
アタッチメント７３は、図１３Ａ、図１３Ｂに示すように、連結材７０の幅寸法に対応して２種類のアタッチメント７３Ａ，７３Ｂが用意されている。アタッチメント７３Ａ，７３Ｂは、長手方向の略中央位置に突起１６に係合する係合孔７４を備えているとともに、これを挟んだ両側表裏面に、第１挟持板１０および第２挟持板２０の係合凹部１７，２４に係合する係合突起７５が形成されている。 When connecting the connecting member 70 to the connecting tool 1, the connecting member 70 is connected using a rectangular parallelepiped attachment 73 having a length slightly smaller than the hole dimension in the width direction of the connecting member 70.
As shown in FIGS. 13A and 13B, the attachment 73 has two types of attachments 73A and 73B corresponding to the width dimension of the connecting member 70. Attachment 73A, 73B is provided with the engagement hole 74 engaged with the processus | protrusion 16 in the approximate center position of a longitudinal direction, and the 1st clamping board 10 and the 2nd clamping board 20 of the both sides front and back which pinched | interposed this Engagement protrusions 75 that engage with the engagement recesses 17 and 24 are formed.

従って、図１２に示す連結材７１を連結するには、図１３Ａのアタッチメント７３Ａを第１挟持板１０の係合凹部１７に係合させるとともに、このアタッチメント７３Ａに連結材７１を嵌め込んだのち、第２挟持板２０を第１挟持板１０に対して伏した状態に回動すればよい。
また、サイズの異なる連結材、例えば、連結材７１の幅方向寸法より小さい連結材を連結するには、図１３Ｂのアタッチメント７３Ｂを第１挟持板１０の係合凹部１７に係合させるとともに、このアタッチメント７３Ｂに幅寸法の小さい連結材を嵌め込んだのち、第２挟持板２０を第１挟持板１０に対して伏した状態に回動すればよい。 Therefore, in order to connect the connecting member 71 shown in FIG. 12, the attachment 73A of FIG. 13A is engaged with the engaging recess 17 of the first sandwiching plate 10, and the connecting member 71 is fitted into the attachment 73A. What is necessary is just to rotate the 2nd clamping board 20 to the state which fell down with respect to the 1st clamping board 10. FIG.
Further, in order to connect connecting members of different sizes, for example, connecting members smaller than the width direction dimension of the connecting member 71, the attachment 73B of FIG. 13B is engaged with the engaging recess 17 of the first holding plate 10, and this After fitting a connecting material having a small width dimension into the attachment 73 </ b> B, the second holding plate 20 may be rotated to a state where it is depressed with respect to the first holding plate 10.

（第３変形例）
第２変形例では、矩形輪状に形成された連結材７０を、この連結材７０の幅方向の孔寸法より僅かに小さい長さ寸法を有する直方体形状のアタッチメント７３を用いて連結するようにしたが、矩形輪状に形成された連結材７０を２つに分割し、その一方に引掛孔７を形成するとともに、他方を一方に対して着脱可能に係合できるように構成してもよい。
例えば、図１４に示すように、中央に矩形状の引掛孔７を有し、両端に係合溝７６を有する第１連結片７０Ａと、矩形輪状の長辺側の一方を切り欠いた開口端に係合部７７を形成したＣ字形状の第２連結片７０Ｂとから構成し、第２連結片７０Ｂの係合部７７を第１連結片７０Ａの係合溝７６に着脱可能に係合するようにしてもよい。
このようにすれば、予め、ベルトの先端をループ状に縫製した状態であっても、ベルトの先端のループに第２連結片７０Ｂを通すことができる利点がある。 (Third Modification)
In the second modification, the connecting member 70 formed in a rectangular ring shape is connected using a rectangular parallelepiped attachment 73 having a length dimension slightly smaller than the hole dimension in the width direction of the connecting member 70. The connecting member 70 formed in the shape of a rectangular ring may be divided into two, and the hook hole 7 may be formed in one of the two, and the other may be detachably engaged with the other.
For example, as shown in FIG. 14, a first connecting piece 70 </ b> A having a rectangular hooking hole 7 in the center and engaging grooves 76 at both ends, and an open end obtained by cutting out one of the long sides of the rectangular ring shape. The second connecting piece 70B is formed with a C-shaped second connecting piece 70B formed with an engaging portion 77, and the engaging portion 77 of the second connecting piece 70B is detachably engaged with the engaging groove 76 of the first connecting piece 70A. You may do it.
In this manner, there is an advantage that the second connecting piece 70B can be passed through the loop at the front end of the belt even when the front end of the belt is sewn in a loop shape.

（第４変形例）
前記実施形態および前記各変形例では、１つの連結材は、１つの連結具に連結される構造であったが、１つの連結材に対して２つの連結具が連結される構造にもできる。
例えば、図１５に示す連結材９０は、矩形板状で、一方の長辺側に沿ってベルト挿通孔６が形成され、他方の長辺側の角部に引掛孔７Ａ，７Ｂがそれぞれ形成されている。図１６に示すように、これらの各引掛孔７Ａ，７Ｂを異なる連結具１に連結すれば、３本のベルトなどを交差して連結できるので、より自在なベルトの利用が可能である。 (Fourth modification)
In the embodiment and each of the modifications, one connecting member has a structure that is connected to one connecting member. However, a structure in which two connecting members are connected to one connecting member may be used.
For example, the connecting member 90 shown in FIG. 15 has a rectangular plate shape, the belt insertion hole 6 is formed along one long side, and the hooking holes 7A and 7B are formed at the corners on the other long side. ing. As shown in FIG. 16, if these hooking holes 7A and 7B are connected to different connecting devices 1, three belts can be crossed and connected, so that a more flexible belt can be used.

（第５変形例）
前記実施形態では、第１挟持板１０に突起１６を一体成形し、この突起１６に係合部３０を形成するとともに、第２挟持板２０に係合部３０と係合する一対のスライド部材４１Ａ，４１Ｂを有する被係合部４０を構成したが、これに限らず、他の構造の被係合部でもよい。
例えば、図１７に示すように、第１挟持板１０の幅方向（連結方向軸線Ｌに対して略直交する方向）に沿って突条１６Ａを一体成形し、この突条１６Ａの先端に係合部３０Ａを形成するとともに、第２挟持板２０の幅方向（連結方向軸線Ｌに対して略直交する方向）に沿って突条１６Ａと係合する被係合部４０Ａを形成する。係合部３０Ａは、先端に頭部が軸部よりも大きくなったやじり状に形成されている。被係合部４０Ａは、開口よりも奥部が広くなった蟻溝形状に形成されている。これにより、第２挟持板２０が第１挟持板１０に対して伏した状態に回動されると、係合部３０Ａは、被係合部４０Ａの開口より奥へ入って蟻溝状の被係合部４０Ａに係合される。
このようにすれば、被係合部４０Ａを極めてシンプルな構造に形成できる。 (5th modification)
In the embodiment, the protrusion 16 is integrally formed on the first clamping plate 10, the engaging portion 30 is formed on the protrusion 16, and the pair of slide members 41 </ b> A that engage with the engaging portion 30 on the second clamping plate 20. However, the present invention is not limited to this, and an engaged portion having another structure may be used.
For example, as shown in FIG. 17, a protrusion 16A is integrally formed along the width direction of the first sandwiching plate 10 (a direction substantially orthogonal to the connecting direction axis L) and is engaged with the tip of the protrusion 16A. A portion 30A is formed, and an engaged portion 40A that engages with the protrusion 16A is formed along the width direction of the second sandwiching plate 20 (a direction substantially orthogonal to the connecting direction axis L).
