Description

この発明は、少なくとも二つの部材を重なり合った状態に保つことのできるファスナに関する。   The present invention relates to a fastener capable of keeping at least two members overlapped.

二つの部材、例えば二つの板状の部材それぞれに形成された透孔にファスナを挿通して、それら二つの部材を重なり合った状態に保つことのできるファスナは周知である。   Fasteners that are capable of passing fasteners through through holes formed in two members, for example, two plate-like members, and keeping the two members overlapped are well known.

例えば、特開平８−３３４１０９号公報（特許文献１）に記載のクリップは、この種のファスナの一つであって、クリップ本体とピンとを有している。重ね合せようとする二つの部材それぞれに形成された透孔にクリップ本体を挿通した後に、クリップ本体に対してピンを圧入すると、クリップ本体の脚部の先端側の径が拡大して、透孔からのクリップ本体の抜脱が不能となることによって二つの部材を重ね合せた状態に保つことができる。   For example, a clip described in Japanese Patent Application Laid-Open No. 8-334109 (Patent Document 1) is one of this type of fastener, and has a clip body and a pin. After inserting the clip body into the through-holes formed in each of the two members to be overlapped, press the pin into the clip body, the diameter on the tip side of the leg of the clip body will increase, and the through-hole Since the clip main body cannot be removed from the two, the two members can be kept in an overlapped state.

また、特開２０１１−９４６３６号公報（特許文献２）に記載のファスナは、円筒状部材と、円筒状部材に挿入されたピン部材とを有する。重ね合せようとする二つの部材のうちの一方の部材に形成されている透孔にその一方の部材の表面側から円筒状部材を挿入すると、円筒状部材において径方向の外側へ延びる弾性変形可能なストッパ部が一方の部材における透孔の周縁部にその一方の部材の裏面側から当接して、円筒状部材が一方の部材から抜け落ちることを防ぐことができる。   Moreover, the fastener of Unexamined-Japanese-Patent No. 2011-94636 (patent document 2) has a cylindrical member and the pin member inserted in the cylindrical member. When a cylindrical member is inserted into the through hole formed in one of the two members to be superimposed from the surface side of the one member, the cylindrical member can be elastically deformed to extend radially outward. It is possible to prevent the cylindrical member from coming off from one member by contacting the peripheral portion of the through hole in the one member from the back side of the one member.

特開平８−３３４１０９号公報JP-A-8-334109 特開２０１１−９４６３６号公報JP 2011-94636 A

前記従来のクリップは、二つの部材を重ね合せた状態に保つことはできるのだが、重ね合わせた状態にある二つの部材から抜き取ることができない。したがって、このクリップは、繰り返し使用することができない。   The conventional clip can keep the two members overlapped, but cannot be pulled out of the two members in the overlapped state. Therefore, this clip cannot be used repeatedly.

また、前記従来のファスナは、一方の部材の透孔に挿入した円筒状部材をその透孔から抜き取って再度使用することが不可能ではないにしても、抜き取ることを容易にする手段を有するものではない。したがって、このファスナもまた、実質的な意味において、繰り返し使用することができるとはいい難い。
そこで、この発明は、従来のファスナに対して、それを繰り返し使用することができるように改良を施すことを課題にしている。 Further, the conventional fastener has means for facilitating extraction even if it is not impossible to extract the cylindrical member inserted into the through hole of one member from the through hole and use it again. is not.

In the first swirler 15 of the phantom line, the first stopper portion 15a retreats to the inside of the shaft portion 2, and the first stopper portion 15a and the second member 32 are in contact with the peripheral portion of the second through hole 32a. It can be solved.

図７は、図２のＶＩＩ−ＶＩＩ線断面図である。図７は図６に似た図であるが、図７には第１旋回子１５ではなくて第２旋回子１６の全体形状が見えている。第２旋回子１６は、第１旋回子１５と同一形状を有する板状のものであって、下端部分３３ｒ、上端部分３４ｒ、側面部分３６ｒ、第２ストッパー部１６ａ、第２カムフォロワー部１６ｂを有し、板面が第１旋回子１５の板面と対抗するように配置されている。図６においての時計方向Ｃ１は、図７において図示の方向となる。すなわち、第２旋回子１６が時計方向へ旋回するというときには、第２旋回子１６が図７における矢印Ｃ１の示す方向へ旋回することを意味している。その第２旋回子１６は、時計方向Ｃ１と反時計方向Ｃ２とに旋回し得るように支軸７に支えられ、トーションばね２７の第２端部２７ｂによって、反時計方向Ｃ２（図１参照）に向かって付勢され、第２ストッパー部１６ａが第２部材３２における第２透孔３２ａの周縁部に圧接している。拡径部３のカム部材８は、下端部分８ｂに第２カム部４０ｒを有する。第２カム部４０ｒには、反時計方向Ｃ２へ付勢されている第２旋回子１６の第２カムフォロワー部１６ｂが圧接可能である。 7 is a cross-sectional view taken along line VII-VII in FIG. FIG. 7 is a view similar to FIG. 6, but in FIG. 7, the entire shape of the second swirler 16 is visible instead of the first swirler 15. The second swirler 16 is a plate having the same shape as the first swirler 15, and includes a lower end portion 33r, an upper end portion 34r, a side surface portion 36r, a second stopper portion 16a, and a second cam follower portion 16b. And the plate surface is arranged so as to oppose the plate surface of the first swirler 15. Clockwise C 1 to 6, a direction shown in FIG. That is, when that second swirl member 16 is pivoted in the clockwise direction, which means that the second swirl member 16 pivots in the direction indicated by the arrow C 1 in FIG. Its second swirl member 16 is supported on a support shaft 7 so as to pivot in a clockwise direction C 1 and the counterclockwise direction C 2, the second end 27b of the torsion spring 27, the counterclockwise direction C 2 (FIG. 1), the second stopper portion 16a is in pressure contact with the peripheral edge portion of the second through hole 32a in the second member 32. The cam member 8 of the enlarged diameter portion 3 has a second cam portion 40r at the lower end portion 8b. The second cam portion 40r, the second cam follower portion 16b of the second swirl member 16 which is urged in the counterclockwise direction C 2 can be pressed.

図７においてもまた、コイルばね２９の付勢に抗して下降したカム部材８の一部分が仮想線で示されている。下降したカム部材８は、第２カム部４０ｒが第２旋回子１６の第２カムフォロワー部１６ｂを押圧し、第２旋回子１６を時計方向Ｃ１へ旋回させて仮想線の状態にする。仮想線の第２旋回子１６では、第２ストッパー部１６ａが軸部２の内側に退却して、第２ストッパー部１６ａと第２部材３２との当接が解ける。 Also in FIG. 7, a part of the cam member 8 lowered against the urging of the coil spring 29 is indicated by an imaginary line. In the lowered cam member 8, the second cam portion 40 r presses the second cam follower portion 16 b of the second revolving element 16, and the second revolving element 16 is swung in the clockwise direction C 1 to be in an imaginary line state. In the second swirler 16 of the imaginary line, the second stopper portion 16a retreats to the inside of the shaft portion 2, and the contact between the second stopper portion 16a and the second member 32 is released.

図示例において、第１部材３１の第１透孔３１ａと、第２部材３２の第２透孔３２ａとは、径方向Ｂの寸法が軸部２の径方向Ｂの寸法よりも大きく、かつ、拡径部３の径方向Ｂの寸法よりも小さく作られている。押しボタン式のカム部材８をコイルばね２９の付勢に抗して押圧して、軸部２の第１旋回子１５と第２旋回子１６とが図６，７の仮想線の状態となり、第１ストッパー部１５ａと第２ストッパー部１６ａとが軸部２の内側に退却しているときには、軸部２を第１部材３１と第２部材３２とから抜き取り、ファスナ１を第１，第２部材３１，３２から外すことができ、必要ならばそのファスナ１を再度使用することができる。   In the illustrated example, the first through hole 31a of the first member 31 and the second through hole 32a of the second member 32 have a dimension in the radial direction B larger than a dimension in the radial direction B of the shaft portion 2, and It is made smaller than the dimension in the radial direction B of the enlarged diameter portion 3. The push button type cam member 8 is pressed against the urging force of the coil spring 29 so that the first swivel 15 and the second swivel 16 of the shaft portion 2 are in the state of phantom lines in FIGS. When the first stopper portion 15a and the second stopper portion 16a are retracted to the inside of the shaft portion 2, the shaft portion 2 is extracted from the first member 31 and the second member 32, and the fastener 1 is first and second. The members 31 and 32 can be removed, and the fastener 1 can be used again if necessary.

ファスナ１を使用して第１部材３１と第２部材３２とを重ね合せた状態に保つための操作は、次のようにする。すなわち、自然状態にあるファスナ１は、図１の形状のファスナ１に近似したものであって、第１旋回子１５は、時計方向Ｃ１へのばね付勢下にあって第１ストッパー部１５ａが第１スリット１１ａを通って軸部２の外側へ突出している。また、第２旋回子１６は、反時計方向Ｃ２へのばね付勢下にあって、第２ストッパー部１６ａが第２スリット１２ａを通って軸部２の外側へ突出している。この状態のファスナ１における軸部２を図１に仮想線で示されている第１部材３１の第１透孔３１ａと第２部材３２の第２透孔３２ａとに挿通すると、第１旋回子１５は第１ストッパー部１５ａにおける下縁１５ｄが第１部材３１の第１透孔３１ａの周縁部に圧接し、第２旋回子１６は第２ストッパー部１６ａにおける下縁１６ｄが第１透孔３１ａの周縁部に圧接して、第１旋回子１５が反時計方向Ｃ２へ旋回して軸部２の内側に退却する一方、第２旋回子１６が時計方向Ｃ１へ旋回して軸部２の内側に退却することにより、軸部２の第１，第２透孔３１ａ，３２ａに対する挿通が可能になる。拡径部３が第１部材３１に当接するときには、第１，第２ストッパー部１５ａ,１６ａがトーションばね２７の付勢作用によって軸部２の外側へ出て、図１に実線で例示の如く、第１，第２部材３１，３２を重なり合った状態に維持することができる。 The operation for keeping the first member 31 and the second member 32 overlapped using the fastener 1 is as follows. That is, the fastener 1 in a natural state, there is approximate to the fastener 1 of the shape of FIG. 1, the first swirl member 15, the first stopper portion 15a be under spring bias in the clockwise direction C 1 Protrudes to the outside of the shaft portion 2 through the first slit 11a. The second swirl member 16 be under spring bias in the counterclockwise direction C 2, the second stopper portion 16a protrudes outward of the shaft portion 2 passes through the second slit 12a. When the shaft portion 2 of the fastener 1 in this state is inserted into the first through hole 31a of the first member 31 and the second through hole 32a of the second member 32 shown by phantom lines in FIG. 15, the lower edge 15 d of the first stopper portion 15 a is in pressure contact with the peripheral edge portion of the first through hole 31 a of the first member 31, and the lower edge 16 d of the second swinger 16 is the first through hole 31 a of the second stopper portion 16 a. pressed against the peripheral portion, while the first swirl member 15 is retracted to the inside of the shank 2 to pivot counterclockwise C 2, the shaft portion 2 second swirl member 16 is pivoted clockwise C 1 By retreating inward, the shaft part 2 can be inserted into the first and second through holes 31a and 32a. When the enlarged diameter portion 3 comes into contact with the first member 31, the first and second stopper portions 15a and 16a are moved out of the shaft portion 2 by the urging action of the torsion spring 27, and are illustrated by a solid line in FIG. The first and second members 31 and 32 can be maintained in an overlapping state.

図８は、ファスナ１の使用態様の一例を示す図４と同様な図である。ただし、ファスナ１は、第１部材３１における第１透孔３１ａにのみ挿通されていて、第２部材３２における第２透孔３２ａには未だ挿通されていない。その第１部材３１では、第１透孔３１ａの周縁部の一部分に上方Ａ１に向かっての一対の起立部４１が径方向Ｂにおいて対向するように形成され、その起立部４１がファスナ１における拡径部３に形成された一対の凹部９のそれぞれに収容されている。一対の起立部４１の上端部４１ａそれぞれは、凹部９の底面部分９ａに圧接することによって拡径部３を径方向Ｂにおいて狭持している。それゆえ、第１透孔３１ａに挿通されたファスナ１は、第１透孔３１ａの内側で揺れ動くことがなく、軸部２を第２透孔３２ａへ挿通するときの作業に手間がかかるということがない。このように作用する一対の起立部４１は、上端部４１ａどうしの離間寸法を凹部９における底面部分９ａどうしの間の寸法よりも僅かに小さくすることによって得ることができる。 FIG. 8 is a view similar to FIG. 4 showing an example of a usage mode of the fastener 1. However, the fastener 1 is inserted only through the first through hole 31a in the first member 31 and has not been inserted through the second through hole 32a in the second member 32 yet. In the first member 31, a pair of upright portions 41 toward the upper side A 1 are formed in a part of the peripheral edge portion of the first through hole 31 a so as to face each other in the radial direction B, and the upright portions 41 are formed in the fastener 1. Each of the pair of recesses 9 formed in the enlarged diameter portion 3 is accommodated. Each of the upper end portions 41 a of the pair of upstanding portions 41 holds the enlarged diameter portion 3 in the radial direction B by being pressed against the bottom surface portion 9 a of the recess 9. Therefore, the fastener 1 inserted through the first through hole 31a does not sway inside the first through hole 31a, and it takes time and labor to insert the shaft portion 2 into the second through hole 32a. There is no. The pair of upright portions 41 acting in this way can be obtained by making the distance between the upper end portions 41 a slightly smaller than the size between the bottom surface portions 9 a in the recess 9.

この発明において、ファスナ１を使用して重ね合せる部材は、第１部材３１と第２部材３２との二つであることに限定されるわけではない。第１部材３１と第２部材３２との間に少なくとも一つの部材を介在させ、これら部材のすべてをファスナ１によって重ね合せることも可能である。また、ファスナ１における軸部２は、図示例の角筒状のものであることに限定されるわけではない。円筒状の軸部を使用してこの発明を実施することも可能である。さらにはまた、第１旋回子１５と第２旋回子１６とに対する付勢が、図示例の如く一つのトーションばね２７によって提供されることに代えて、個別に作られた第２ばねと第３ばねとのそれぞれによって提供されていてもよい。カム部材８を付勢するためのコイルばね２９は、その個数が図示例の２個（図６，７参照）に限定されるものではなく、１個であってもよいし、３個以上であってもよい。   In the present invention, the number of members that can be overlapped using the fastener 1 is not limited to two, that is, the first member 31 and the second member 32. It is also possible to interpose at least one member between the first member 31 and the second member 32 and to superimpose all of these members by the fastener 1. Further, the shaft portion 2 in the fastener 1 is not limited to the rectangular tube shape in the illustrated example. It is also possible to carry out the present invention using a cylindrical shaft portion. Furthermore, instead of the biasing of the first and second slewing elements 15 and 16 being provided by a single torsion spring 27 as shown, the second and third springs are made separately. It may be provided by each of the springs. The number of coil springs 29 for biasing the cam member 8 is not limited to two in the illustrated example (see FIGS. 6 and 7), and may be one, or three or more. There may be.
