Description

本出願はリベットに関する。   This application relates to rivets.

従来、２枚の板を締結する締結部材として、リベットが知られている。リベットは、ドーム状の先端部に切り込みがある樹脂製の筒状の本体の開口部にピンを挿入し、ピンの頭部をプッシュすることによってピンの軸を先端部から突出させ、先端部を広げて複数の板等を固定する簡易型ファスナーである。この種のリベットはプッシュリベットとも呼ばれる。リベットによる板材の締結は、従来のネジによる締付けによる固定方法と異なり、ピンを 押し込むだけで容易にプリント板や複数の板の固定が可能である。   Conventionally, a rivet is known as a fastening member for fastening two plates. A rivet inserts a pin into the opening of a cylindrical body made of resin with a dome-shaped tip, and pushes the head of the pin to project the pin shaft from the tip. A simple fastener that spreads and fixes a plurality of plates and the like. This type of rivet is also called a push rivet. Unlike conventional fixing methods using screws, rivets can be used to easily fix printed boards and multiple boards simply by pressing pins.

このようなリベットの比較技術として、例えば特許文献１に、自動車の内装部品等の被取付部材をボディに着脱可能に取り付ける、被取付部材の取り付け用クリップが開示されている。特許文献１に開示のクリップでは、クリップ本体に設けた開脚状態の脚部が、取付面の孔を通過する時に収縮して閉脚し、通過後に開脚するので被取付部材が取付面に取り付けられる。また、クリップを取り外す時は、クリップ本体に挿通されているプッシュピンを押すと、プッシュピンの移動で開脚しているクリップ本体の脚部が閉脚状態でロックするので取付面の孔との係合が解除され、被取付部材を取付面から取り外せる。   As a comparative technique for such rivets, for example, Patent Document 1 discloses a clip for attaching a member to be attached such that a member to be attached such as an interior part of an automobile is detachably attached to the body. In the clip disclosed in Patent Document 1, the leg portion in the open leg state provided on the clip body contracts and closes when passing through the hole on the attachment surface, and opens after passing, so the attached member is attached to the attachment surface. It is done. When removing the clip, if the push pin inserted into the clip body is pressed, the leg of the clip body that is opened by the movement of the push pin will lock in the closed state, so The joint is released and the mounted member can be removed from the mounting surface.

特開平５−０３４３３１号公報JP-A-5-034331

ところが、特許文献１におけるクリップでは、開脚状態の脚部にロック機構がないので、縦方向の振動によって開脚状態の脚部が閉脚するとクリップ本体が取付面の孔から抜ける虞があるという課題がある。また、クリップを取り付けた後に取り外すと、脚部が閉脚状態でロックされるので、クリップ本体の再使用が困難であった。更に、特許文献１におけるクリップは、被取付部材を取り付ける取付面の板厚がバラツクと取り付けられなかった。   However, since the clip in Patent Document 1 does not have a locking mechanism in the leg portion in the open leg state, there is a possibility that the clip body may come out of the hole in the mounting surface when the leg leg in the open leg state is closed by the vibration in the vertical direction. There is. Further, when the clip is removed after being attached, the leg portion is locked in a closed state, so that it is difficult to reuse the clip body. Furthermore, the clip in Patent Document 1 cannot be mounted with variations in the thickness of the mounting surface to which the mounted member is mounted.

１つの側面では、本出願は、板厚が異なっても複数の板材の締結が可能であり、取付後はロック機構によって抜けが発生せず、取り外し操作で容易に取り外せると共に、取り外し後は再使用が可能なリベットを提供することを目的とする。   In one aspect, the present application allows a plurality of plate materials to be fastened even if the plate thickness is different, and does not come off by a lock mechanism after attachment, and can be easily removed by a removal operation and reused after removal. The purpose is to provide rivets that can be used.

以下、添付図面を用いて本出願の実施の形態を、具体的な実施例に基づいて詳細に説明する。   Hereinafter, embodiments of the present application will be described in detail based on specific examples with reference to the accompanying drawings.

図１（ａ）は、板状の第１部材７１と第２部材７２を結合するのに用いられる比較技術のリベット９を示すものである。リベット９にはソケット８０とプッシュピン９０があり、一般に合成樹脂で形成されている。ソケット８０の先端部８１には貫通孔８４が設けられており、この貫通孔８４から胴部８２に渡って複数のスリット（切れ込み）が設けられている。本図にはスリットは図示していない。また、ソケット８０の後端部８３は膨出されてフランジ８５が形成されている。プッシュピン９０は頭部９１に軸部９２が突設されたものであり、先端部９３及び軸部９２がソケット８０に挿入されている。 FIG. 1A shows a rivet 9 of a comparative technique used for joining a plate-like first member 71 and a second member 72. The rivet 9 has a socket 80 and a push pin 90, and is generally formed of a synthetic resin. A through-hole 84 is provided in the distal end portion 81 of the socket 80, and a plurality of slits (cuts) are provided from the through-hole 84 to the trunk portion 82. The slit is not shown in the figure. Further, the rear end portion 83 of the socket 80 is bulged to form a flange 85. The push pin 90 has a head portion 91 projecting from a shaft portion 92, and a tip portion 93 and a shaft portion 92 are inserted into the socket 80.

締結される第１部材７１と第２部材７２にはそれぞれ貫通孔７３．７４があり、リベット９のソケット８０の胴部８２がこの貫通孔７３．７４に挿通される。ソケット８０はフランジ８５が第２部材７２の表面に達するまで、貫通孔７３．７４に挿通され、この状態で、ソケット８０の先端部８１は貫通孔７３から突出している。第１部材７１と第２部材７２を結合する場合は、プッシュピン９０の頭部９１を押すと、図１（ｂ）に示すように、軸部９２の先端部９３がソケット８０の先端部８１を押し広げてソケット８０の胴部８２の直径を大きくする。この結果、ソケット８０が貫通孔７３，７４から抜けなくなり、第１部材７１と第２部材７２が結合される。   The first member 71 and the second member 72 to be fastened each have a through hole 73.74, and the body portion 82 of the socket 80 of the rivet 9 is inserted into the through hole 73.74. The socket 80 is inserted into the through hole 73.74 until the flange 85 reaches the surface of the second member 72. In this state, the distal end portion 81 of the socket 80 protrudes from the through hole 73. When the first member 71 and the second member 72 are coupled, when the head 91 of the push pin 90 is pushed, the tip portion 93 of the shaft portion 92 becomes the tip portion 81 of the socket 80 as shown in FIG. Is expanded to increase the diameter of the body portion 82 of the socket 80. As a result, the socket 80 cannot be removed from the through holes 73 and 74, and the first member 71 and the second member 72 are coupled.

比較技術のリベット９は、第１部材７１と第２部材７２の締結を解除する場合は、プッシュピン９０の頭部９１をペンチのような工具で掴んで引張り、軸部９２をソケット８０から引き抜く。このように、比較技術のリベット９は容易に着脱できるが、外乱等によってプッシュピン９０がソケット８０から抜けやすいという課題がある。また、プッシュピン９０の頭部９１を工具で掴んで軸部９２を引き抜くと、工具によって頭部９１が潰れ、リベット９は再使用が出来なくなる。   In the rivet 9 of the comparative technique, when the fastening of the first member 71 and the second member 72 is released, the head 91 of the push pin 90 is grasped and pulled with a tool such as pliers, and the shaft portion 92 is pulled out from the socket 80. . Thus, although the rivet 9 of the comparative technique can be easily attached and detached, there is a problem that the push pin 90 is easily detached from the socket 80 due to a disturbance or the like. Further, when the head portion 91 of the push pin 90 is grasped with a tool and the shaft portion 92 is pulled out, the head portion 91 is crushed by the tool and the rivet 9 cannot be reused.

（第１実施例のリベット）
本出願では比較技術のリベット９の課題を解消するリベットを提供する。図２（ａ）は第１実施例のリベット１の構成部材を示している。第１実施例のリベット１は、第１筒状部材１０、第２筒状部材２０、ロック部材３０及びピン部材４０を備えている。第２筒状部材２０は、図２（ｂ）に示すように、ロック部材３０とピン部材４０を内蔵した状態で第１筒状部材１０に後端部１３から挿入される。図２（ｃ）は図２（ａ）のＡ部を拡大して示すものである。まず、第１筒状部材１０、第２筒状部材２０、ロック部材３０及びピン部材４０の各個についてそれぞれその構造を説明する。 (Rivets of the first embodiment)
The present application provides a rivet that solves the problem of the rivet 9 of the comparative technique. Fig.2 (a) has shown the structural member of the rivet 1 of 1st Example. The rivet 1 according to the first embodiment includes a first tubular member 10, a second tubular member 20, a lock member 30, and a pin member 40. As shown in FIG. 2B, the second tubular member 20 is inserted into the first tubular member 10 from the rear end portion 13 with the lock member 30 and the pin member 40 built therein. FIG. 2 (c) is an enlarged view of portion A in FIG. 2 (a). First, the structure of each of the first cylindrical member 10, the second cylindrical member 20, the lock member 30, and the pin member 40 will be described.

（第１筒状部材）
第１筒状部材１０の構造は図２（ａ）、図２（ｂ）、図３（ａ）及び図３（ｂ）等に示される。第１筒状部材１０は先端部１１、胴部１２及び後端部１３を備える。第１筒状部材１０の材料は、先端部１１が広がる材料であれば、樹脂でも金属でも良い。先端部１１はドーム状をしており、最先端部に貫通孔１４がある。貫通孔１４の縁部から胴部１２に向かって複数のスリット（切れ込み）１５が設けられている。本実施例ではスリット１５は胴部１２の中ほどまで延伸されて設けられているが、スリット１５の長さは限定されるものではなく、リベット１が結合する板状の部材の板厚に合わせれば良い。また、スリット１５は通路１８に何も挿入されていない状態では隙間が無い状態であるが、隙間があっても良い。 (First cylindrical member)
The structure of the first tubular member 10 is shown in FIGS. 2 (a), 2 (b), 3 (a), 3 (b), and the like. The first tubular member 10 includes a front end portion 11, a body portion 12 and a rear end portion 13. As long as the material of the 1st cylindrical member 10 is the material which the front-end | tip part 11 spreads, resin or a metal may be sufficient. The distal end portion 11 has a dome shape, and a through hole 14 is provided at the most distal end portion. A plurality of slits (cuts) 15 are provided from the edge of the through hole 14 toward the body 12. In this embodiment, the slit 15 is provided so as to extend to the middle of the body portion 12, but the length of the slit 15 is not limited, and can be adjusted to the plate thickness of the plate-like member to which the rivet 1 is coupled. It ’s fine. The slit 15 is in a state where nothing is inserted into the passageway 18 is a gap absence, there may be a gap.

また、後端部１３は膨出されてフランジ１６が形成されている。フランジ１６により、締結する複数の板部材の取付孔に先端部１１と胴部１２が挿入されたリベット１の第１筒状部材１０は、その進入が係止される。一方、胴部１２の内部にある第２筒状部材を移動させるための通路１８の内周面には、後端部１３寄りに係止溝１７が設けられている。係止溝１７は後端部１３側が通路１８に垂直な面になっており、先端部１１側がテーパ面になっている。係止溝１７の機能については後述する。   Further, the rear end portion 13 is bulged to form a flange 16. The first cylindrical member 10 of the rivet 1 in which the distal end portion 11 and the body portion 12 are inserted into the mounting holes of the plurality of plate members to be fastened is locked by the flange 16. On the other hand, a locking groove 17 is provided near the rear end portion 13 on the inner peripheral surface of the passage 18 for moving the second cylindrical member inside the trunk portion 12. The locking groove 17 has a surface perpendicular to the passage 18 on the rear end 13 side, and a tapered surface on the front end 11 side. The function of the locking groove 17 will be described later.

（第２筒状部材）
第２筒状部材２０の構造は図２（ａ）、図２（ｂ）及び図４（ａ）から図４（ｄ）等に示される。第２筒状部材２０は先端部２１、胴部２２及び後端部２３を備える。第２筒状部材２０の材料も樹脂でも金属でも良い。図２（ａ）に示すように、先端部２１はドーム状をしており、先端部２１と胴部２２の間にテーパ状の先端周辺部２４がある。先端周辺部２４には、ロック部材３０を収容するロック部材収容孔２５が設けられている。胴部２２は円柱状であり、後端部２３には胴部２２に対して膨出されて直径が次第に増大するテーパ部２３Ｔがある。 (Second cylindrical member)
The structure of the second cylindrical member 20 is shown in FIG. 2A, FIG. 2B, FIG. 4A to FIG. The second cylindrical member 20 includes a front end portion 21, a body portion 22 and a rear end portion 23. The material of the second cylindrical member 20 may be resin or metal. As shown in FIG. 2A, the distal end portion 21 has a dome shape, and a tapered distal end peripheral portion 24 is provided between the distal end portion 21 and the trunk portion 22. The distal end peripheral portion 24 is provided with a lock member accommodation hole 25 for accommodating the lock member 30. The trunk portion 22 has a cylindrical shape, and a rear end portion 23 has a tapered portion 23T that is bulged with respect to the trunk portion 22 and gradually increases in diameter.

第２筒状部材２０は図４（ａ）から図４（ｃ）に示すように、軸線を通る面で左右に二分割することができる。これは、二分割にしないと、内部にピン部材４０を収容できないからである。第２筒状部材２０の内部には、図４（ａ）に示すように、先端周辺部２４にロック部材収容孔２５があり、ロック部材収容孔２５にはロック部材３０の基部を回動自在に保持する軸穴２５Ｈと後述するロック部材の脚部の回転を係止するストッパ２５Ｓがある。ロック部材収容孔２５には、第２筒状部材２０の後端部２３まで続く内部通路２６が形成されており、この内部通路２６の途中には拡径部２６Ｅがある。また、内部通路２６の後端部２３側は次第に拡径されてテーパ部２６Ｔとなっている。   As shown in FIG. 4A to FIG. 4C, the second cylindrical member 20 can be divided into left and right parts on a plane passing through the axis. This is because the pin member 40 cannot be accommodated inside unless divided into two.

（第２筒状部材の組立）
第１筒状部材１０、第２筒状部材２０、ロック部材３０及びピン部材４０を備えるリベット１の組立について説明する。リベット１を組み立てる場合は、まず、図４（ａ）に示すロック部材３０を、図４（ｂ）に示すように、第２筒状部材２０のロック部材収容孔２５に入れる。この時、ロック部材３０の回転軸３２は第２筒状部材２０のロック部材収容孔２５の先端部側に設けられた軸穴２５Ｈに挿入し、ロック部材３０のストッパ片３１Ｓはロック部材収容孔２５の後端部側に設けられたストッパ２５Ｓの内側に位置させる。 (Assembly of the second cylindrical member)
The assembly of the rivet 1 including the first tubular member 10, the second tubular member 20, the lock member 30, and the pin member 40 will be described. When assembling the rivet 1, first, the lock member 30 shown in FIG. 4A is put into the lock member accommodation hole 25 of the second cylindrical member 20 as shown in FIG. 4B. At this time, the rotation shaft 32 of the lock member 30 is inserted into the shaft hole 25H provided on the distal end side of the lock member accommodation hole 25 of the second cylindrical member 20, and the stopper piece 31S of the lock member 30 is the lock member accommodation hole. 25 is positioned inside a stopper 25S provided on the rear end side.

次いで、ピン部材４０の胴部４２と後端部４３を、バネ係止フランジ４４とバネ４５を第２筒状部材２０の拡径部２６Ｅに位置を合わせて、一方の第２筒状部材２０の内部通路２６に入れる。この状態で、他方の第２筒状部材２０を一方の第２筒状部材２０に重ね合せる。ロック部材３０とピン部材４０を挟み込んで二分割された２つの第２筒状部材２０を接合した状態が図４（ｃ）に示される。図４（ｄ）は図４（ｃ）に示した第２筒状部材２０を矢印Ｃ方向から見た状態を示している。   Next, the body portion 42 and the rear end portion 43 of the pin member 40, the spring locking flange 44 and the spring 45 are aligned with the enlarged diameter portion 26E of the second tubular member 20, and one second tubular member 20 is aligned. Into the internal passage 26. In this state, the other second cylindrical member 20 is overlapped with one second cylindrical member 20. FIG. 4C shows a state in which the two second cylindrical members 20 divided into two with the lock member 30 and the pin member 40 interposed therebetween are joined. FIG. 4D shows a state in which the second cylindrical member 20 shown in FIG.

（リベットの組立）
以上のようにして組み立てられた第２筒状部材２０は、図２（ｂ）に示すように、第１筒状部材１０の通路１８の中に、第２筒状部材２０の後端部２３を押しながら挿入する。第２筒状部材２０を第１筒状部材１０の通路１８に挿入する際には、ピン部材４０の後端部４３には力を加えないようにする。第２筒状部材２０の先端周辺部２４に内蔵されたロック部材３０の２つの脚部材３１は、第２筒状部材２０が第１筒状部材１０の外にある時には、図４（ｄ）に示すように、第２筒状部材２０の先端周辺部２４から外に突出している。 (Rivet assembly)
The second cylindrical member 20 assembled as described above is, as shown in FIG. 2B, the rear end portion 23 of the second cylindrical member 20 in the passage 18 of the first cylindrical member 10. Insert while pressing. When the second tubular member 20 is inserted into the passage 18 of the first tubular member 10, no force is applied to the rear end portion 43 of the pin member 40. When the second cylindrical member 20 is outside the first cylindrical member 10, the two leg members 31 of the locking member 30 built in the distal end peripheral portion 24 of the second cylindrical member 20 are shown in FIG. As shown in FIG. 3, the second cylindrical member 20 protrudes outward from the peripheral portion 24 at the front end.

一方、第２筒状部材２０が第１筒状部材１０の通路１８に挿入された状態では、図２（ｂ）に示すように、第２筒状部材２０の先端周辺部２４から外に突出していたロック部材３０の２つの脚部材３１は、通路１８に押される。この結果、ロック部材３０の２つの脚部材３１は、回転軸３２を中心にして回転し、ロック部材収容孔２５の内部に没入する。この時、ロック部材３０の板バネ３３は取付軸３４を中心にして回転し、図２（ｃ）に示すように下に凸に湾曲する。   On the other hand, when the second cylindrical member 20 is inserted into the passage 18 of the first cylindrical member 10, as shown in FIG. The two leg members 31 of the lock member 30 that has been pushed are pushed by the passage 18. As a result, the two leg members 31 of the lock member 30 rotate around the rotation shaft 32 and are immersed in the lock member accommodation hole 25. At this time, the leaf spring 33 of the lock member 30 rotates around the mounting shaft 34 and is curved downwardly as shown in FIG.

（リベットを用いた板状部材の結合）
ここで、リベット１を用いた板状部材の結合動作について説明する。ここでは、図６（ａ）に示すような、電子機器の筐体４の底面５の四隅に設けられた基板支持用の板金６に回路基板７をリベット１を用いて取り付ける場合を説明する。板金６は底面５からＬ字状に折り曲げた状態で設けられており、底面５に平行な部分には取付孔６Ｈが設けられている。回路基板７側にも、板金６の取付孔６Ｈに対応する位置に取付孔７Ｈが設けられている。板金６の上に回路基板７を搭載する場合は、図６（ｂ）に示すように、板金６の上に回路基板７を、板金６の取付孔６Ｈに回路基板７の取付孔７Ｈを合わせて載置し、回路基板７の取付孔７Ｈと板金６の取付孔６Ｈにリベット１を挿通する。 (Combination of plate members using rivets)
Here, the joining operation of the plate-like members using the rivet 1 will be described. Here, the case where the circuit board 7 is attached to the board metal 6 for supporting the board provided at the four corners of the bottom surface 5 of the casing 4 of the electronic device as shown in FIG. The sheet metal 6 is provided in a state of being bent in an L shape from the bottom surface 5, and a mounting hole 6 </ b> H is provided in a portion parallel to the bottom surface 5. An attachment hole 7H is also provided on the circuit board 7 side at a position corresponding to the attachment hole 6H of the sheet metal 6. When the circuit board 7 is mounted on the sheet metal 6, the circuit board 7 is aligned on the sheet metal 6 and the mounting hole 7 H of the circuit board 7 is aligned with the mounting hole 6 H of the sheet metal 6, as shown in FIG. The rivet 1 is inserted into the mounting hole 7H of the circuit board 7 and the mounting hole 6H of the sheet metal 6.

図７（ａ）は、図６（ｂ）に示した板金６に回路基板７を取り付けて固定する場合に、板金６と回路基板７に設けられた取付孔６Ｈ，７Ｈに、リベット１の第１筒状部材１０を挿入した状態を示すものである。第１筒状部材１０は取付孔６Ｈ，７Ｈに、フランジ１６が回路基板７に当接する状態まで差し込むことができる。この状態で、第２筒状部材２０の後端部２３をピン部材４０の後端部４３と共に押して、第２筒状部材２０を第１筒状部材１０に押し込む。この時、ピン部材４０の後端部４３は、図７（ａ）に符号Ｐで示すように、第２筒状部材２０の後端部２３と一緒に押し、ピン部材４０の後端部４３が第２筒状部材２０に対して移動しないようにする。   7A shows a case where the rivet 1 is inserted into the mounting holes 6H and 7H provided in the metal plate 6 and the circuit board 7 when the circuit board 7 is attached and fixed to the metal plate 6 shown in FIG. The state which inserted the 1 cylindrical member 10 is shown. The first tubular member 10 can be inserted into the mounting holes 6H and 7H until the flange 16 is in contact with the circuit board 7. In this state, the second cylindrical member 20 is pushed into the first cylindrical member 10 by pushing the rear end 23 of the second cylindrical member 20 together with the rear end 43 of the pin member 40. At this time, the rear end portion 43 of the pin member 40 is pushed together with the rear end portion 23 of the second tubular member 20 as indicated by the symbol P in FIG. Is prevented from moving relative to the second tubular member 20.

図７（ｂ）は、図７（ａ）に示した状態から第２筒状部材２０をピン部材４０と一緒に押して第２筒状部材２０を第１筒状部材１０の通路１８内を移動させ、第１筒状部材１０の先端部１１を開く動作を示すものである。第２筒状部材２０はその先端部２１が第１筒状部材１０の先端部１１の内面に当接すると、ドーム状の先端部２１が第１筒状部材１０の先端部１１の内面を押す。第１筒状部材１０には、その先端部１１から胴部１２に渡ってスリット１５が設けられているので、ドーム状の先端部２１はスリット１５の幅を拡大させて第１筒状部材１０の先端部１１を押し開く。この時、ロック部材３０の脚部材３１はまだ第２筒状部材２０のロック部材収容孔２５の内部にある。   7B, the second cylindrical member 20 is pushed together with the pin member 40 from the state shown in FIG. 7A to move the second cylindrical member 20 in the passage 18 of the first cylindrical member 10. The operation of opening the distal end portion 11 of the first tubular member 10 is shown. When the distal end portion 21 of the second cylindrical member 20 abuts on the inner surface of the distal end portion 11 of the first tubular member 10, the dome-shaped distal end portion 21 presses the inner surface of the distal end portion 11 of the first tubular member 10. . Since the first cylindrical member 10 is provided with the slit 15 from the distal end portion 11 to the body portion 12, the dome-shaped distal end portion 21 expands the width of the slit 15 and the first cylindrical member 10. The front end portion 11 is pushed open. At this time, the leg member 31 of the lock member 30 is still inside the lock member accommodation hole 25 of the second cylindrical member 20.

第２筒状部材２０が更に押されると、第２筒状部材２０のテーパ部２３Ｔが第１筒状部材１０のフランジ１６に当接する。この状態になると、これ以上第２筒状部材２０は押せなくなり、図７（ｃ）に示すように、第２筒状部材２０の先端周辺部２４が第１筒状部材１０の先端部１１から突出する。第２筒状部材２０の先端周辺部２４が第１筒状部材１０の先端部１１から突出すると、ロック部材３０の脚部材３１を押すものがなくなり、脚部材３１は、板バネ３３の復元力によってロック部材収容孔２５から外部に突出する。   When the second cylindrical member 20 is further pressed, the tapered portion 23T of the second cylindrical member 20 comes into contact with the flange 16 of the first cylindrical member 10. In this state, the second cylindrical member 20 can no longer be pressed, and the distal peripheral portion 24 of the second cylindrical member 20 moves away from the distal end portion 11 of the first cylindrical member 10 as shown in FIG. Protruding. When the distal end peripheral portion 24 of the second tubular member 20 protrudes from the distal end portion 11 of the first tubular member 10, there is nothing to push the leg member 31 of the lock member 30, and the leg member 31 has a restoring force of the leaf spring 33. Projecting outward from the lock member receiving hole 25.

このように、第２筒状部材２０の先端周辺部２４が第１筒状部材１０の先端部１１から突出した状態では、第１筒状部材１０の先端部１１から胴部１２が、スリット１５によって板金６の位置まで押し開かれる。この結果、板金６と回路基板７とが第１筒状部材１０の胴部１２によって締め付けられて固定される。また、第２筒状部材２０の先端周辺部２４が第１筒状部材１０の先端部１１から突出した状態では、板ばね３３の取付軸３４が回転して板バネ３３が湾曲状態から直線状に復帰する。これにより、ロック部材３０の脚部材３１が、回転軸３２を中心にして回転し、押し開かれた第１筒状部材１０の先端部１１にある貫通孔１４よりも外側に開く。このため、図７（ｃ）に示す状態で、第２筒状部材２０を第１筒状部材１０から引き抜こうとしても、脚部材３１が第１筒状部材１０の先端部１１にある貫通孔１４に係止されるので、第２筒状部材２０は第１筒状部材１０から引き抜くことができない。   Thus, in the state where the distal end peripheral portion 24 of the second tubular member 20 protrudes from the distal end portion 11 of the first tubular member 10, the body portion 12 extends from the distal end portion 11 of the first tubular member 10 to the slit 15. Is pushed to the position of the sheet metal 6. As a result, the sheet metal 6 and the circuit board 7 are fastened and fixed by the body 12 of the first cylindrical member 10. Further, in the state where the distal end peripheral portion 24 of the second cylindrical member 20 protrudes from the distal end portion 11 of the first cylindrical member 10, the attachment shaft 34 of the leaf spring 33 rotates and the leaf spring 33 is linearly changed from the curved state. Return to. As a result, the leg member 31 of the lock member 30 rotates around the rotation shaft 32 and opens to the outside of the through hole 14 in the distal end portion 11 of the pushed first tubular member 10. For this reason, even if it is going to pull out the 2nd cylindrical member 20 from the 1st cylindrical member 10 in the state shown in Drawing 7 (c), leg member 31 is a penetration hole in tip part 11 of the 1st cylindrical member 10 14, the second tubular member 20 cannot be pulled out from the first tubular member 10.

なお、板バネ３３が湾曲状態から直線状に戻り、ロック部材３０の脚部材３１が回転軸３２を中心にして回転すると、図２（ｃ）に示される脚部材３１のストッパ片３１Ｓが、ロック部材収容孔２５に設けられたストッパ２５Ｓに当接する。このため、脚部材３１のロック部材収容孔２５からの最大突出量は、板バネ３３の長さに誤差があっても常に同じである。更に、図７（ｄ）に示すように、回路基板７の板厚Ｔ２が図７（ｃ）に示した回路基板７の板厚Ｔ１よりも薄くても、第１筒状部材１０の先端部１１から胴部１２が、スリット１５によって板金６の位置まで同じように押し開かれる。従って、板金６と回路基板７とは、スリット１５の長さの設定により、回路基板７の板厚に関わらず、第１筒状部材１０の胴部１２によって締め付けられて固定される。   When the leaf spring 33 returns to the linear shape from the curved state and the leg member 31 of the lock member 30 rotates about the rotation shaft 32, the stopper piece 31S of the leg member 31 shown in FIG. It abuts against a stopper 25 </ b> S provided in the member accommodation hole 25. For this reason, the maximum protrusion amount of the leg member 31 from the lock member accommodation hole 25 is always the same even if there is an error in the length of the leaf spring 33. Further, as shown in FIG. 7D, even if the plate thickness T2 of the circuit board 7 is smaller than the plate thickness T1 of the circuit board 7 shown in FIG. From 11, the body 12 is pushed in the same way by the slit 15 to the position of the sheet metal 6. Therefore, the sheet metal 6 and the circuit board 7 are fastened and fixed by the body 12 of the first tubular member 10 regardless of the thickness of the circuit board 7 by setting the length of the slit 15.

（リベットの取り外し）
次に、リベット１による板状部材の結合を解除するために、リベット１を引き抜く動作について説明する。ここでは、図７（ｃ）に示した状態から、リベット１を引き抜き、板金６と回路基板７との結合を解除する場合を説明する。リベット１を引き抜く場合は、図８（ａ）に示すように、第２筒状部材２０の後端部２３の内側に位置するピン部材４０の後端部４３を、矢印Ｑで示すように押してピン部材４０を第２筒状部材２０の中に押し込む。この時、ピン部材４０は、拡径部２５Ｅ内にあるバネ４５を収縮させて、第２筒状部材２０の内部通路２６を第２筒状部材２０の先端部２１側に向かって移動する。 (Removal of rivets)
Next, an operation of pulling out the rivet 1 in order to release the coupling of the plate-like member by the rivet 1 will be described. Here, the case where the rivet 1 is pulled out from the state shown in FIG. 7C and the coupling between the sheet metal 6 and the circuit board 7 is released will be described. When pulling out the rivet 1, as shown in FIG. 8A, the rear end portion 43 of the pin member 40 located inside the rear end portion 23 of the second tubular member 20 is pushed as indicated by an arrow Q. The pin member 40 is pushed into the second cylindrical member 20. At this time, the pin member 40 contracts the spring 45 in the enlarged diameter portion 25E and moves the internal passage 26 of the second cylindrical member 20 toward the distal end portion 21 side of the second cylindrical member 20.

すると、ピン部材４０の先端部４１が第２筒状部材２０のロック部材収容孔２５の内部に突出し、押し開かれた第１筒状部材１０の先端部１１にある貫通孔１４の外で直線状に伸びていた板バネ３３を押して下に凸に湾曲させる。板バネ３３が下に凸に湾曲すると、ロック部材３０の脚部材３１が回転軸３２を中心にして回転し、ロック部材収容孔２５内に没入し、脚部材３１が第１筒状部材１０の先端部１１にある貫通孔１４と係合しなくなる。   Then, the front end portion 41 of the pin member 40 protrudes into the lock member accommodation hole 25 of the second cylindrical member 20, and is straight outside the through hole 14 at the front end portion 11 of the pushed first cylindrical member 10. The leaf spring 33 extending in a shape is pushed and curved downward. When the leaf spring 33 is convexly curved downward, the leg member 31 of the lock member 30 rotates about the rotation shaft 32, is immersed in the lock member accommodation hole 25, and the leg member 31 is in the first tubular member 10. No longer engages with the through hole 14 in the tip 11.

ピン部材４０を第２筒状部材２０の中に押し込んだ状態で、図８（ｂ）に符号Ｒで示すように、第２筒状部材２０を第１筒状部材１０に対して引き上げると、脚部材３１が没入している第２筒状部材２０は、第１筒状部材１０の貫通孔１４によって係止されない。このため、第２筒状部材２０は、開いていた第１筒状部材１０の先端部１１を縮めながら内部通路２６内を第１筒状部材１０の後端部１３側に移動することができる。そして、第２筒状部材２０の先端部２１が第１筒状部材１０の先端部１１の内部に入った状態でピン部材４０を押すのを止める。すると、ピン部材４０はバネ４５の付勢力で第２筒状部材２０の内部通路２６内を第２筒状部材２０の後端部２３側に移動する。ピン部材４０の移動はバネ４５が伸長してバネ係止フランジ４４が拡径部２６Ｅの端部に当接するまで続き、バネ係止フランジ４４が拡径部２６Ｅの端部に当接すると図８（ｃ）に示す状態になる。   When the second tubular member 20 is pulled up with respect to the first tubular member 10 in a state where the pin member 40 is pushed into the second tubular member 20, as indicated by reference numeral R in FIG. The second cylindrical member 20 in which the leg member 31 is immersed is not locked by the through hole 14 of the first cylindrical member 10. For this reason, the second tubular member 20 can move in the internal passage 26 toward the rear end portion 13 of the first tubular member 10 while shrinking the tip portion 11 of the opened first tubular member 10. . Then, the pressing of the pin member 40 is stopped in a state in which the distal end portion 21 of the second tubular member 20 enters the inside of the distal end portion 11 of the first tubular member 10. Then, the pin member 40 moves in the internal passage 26 of the second cylindrical member 20 to the rear end portion 23 side of the second cylindrical member 20 by the biasing force of the spring 45. The movement of the pin member 40 continues until the spring 45 extends and the spring locking flange 44 contacts the end of the enlarged diameter portion 26E, and when the spring locking flange 44 contacts the end of the enlarged diameter portion 26E, FIG. The state shown in FIG.

この後も第２筒状部材２０を第１筒状部材１０から引き抜く方向に移動させると、やがて、ロック部材３０が第１筒状部材１０の通路１８に設けられた係止溝１７に対向し、ロック部材３０の脚部材３１が板バネ３３の付勢力で回転して係止溝１７に係合する。このため、第２筒状部材２０は、第１筒状部材１０に対してこれ以上引き抜けなくなり、第２筒状部材２０を更に引っ張ると、第１筒状部材１０を板金６と回路基板７の取付孔６Ｈ，７Ｈから取り外すことができる。リベット１を以上のような操作で板金６と回路基板７の結合部から取り外した後は、リベット１は損傷していないので、再使用が可能である。なお、第１筒状部材１０から第２筒状部材２０だけを引き抜きたい場合は、図８（ｄ）に示す状態で、再度ピン部材４０を第２筒状部材２０の内部に押し込めば良い。   Thereafter, when the second tubular member 20 is moved in the direction of being pulled out from the first tubular member 10, the lock member 30 eventually opposes the locking groove 17 provided in the passage 18 of the first tubular member 10. The leg member 31 of the lock member 30 is rotated by the urging force of the leaf spring 33 and engages with the locking groove 17. Therefore, the second cylindrical member 20 can no longer be pulled out with respect to the first cylindrical member 10, and when the second cylindrical member 20 is further pulled, the first cylindrical member 10 is moved to the sheet metal 6 and the circuit board 7. The mounting holes 6H and 7H can be removed. After the rivet 1 is removed from the joint between the sheet metal 6 and the circuit board 7 by the above operation, the rivet 1 is not damaged and can be reused. When only the second tubular member 20 is to be pulled out from the first tubular member 10, the pin member 40 may be pushed into the second tubular member 20 again in the state shown in FIG.

（第２の実施例のリベット）
第１実施例のリベット１は、図９（ａ）に示すように、第２筒状部材２０の後端部２３がテーパ部２３Ｔによってラッパ状をしており、開口部内にピン部材４０の後端部４３が露出している。これに対して第２実施例のリベット２は、図９（ｂ）及び図１０（ａ）に示すように、第２筒状部材２０Ａの後端部２３の構造が、第１実施例のリベット１の第２筒状部材２０の後端部２３の構造と異なる。即ち、図１０（ａ）に示す第２実施例のリベット２の構造において、Ｄ−Ｄ線から下の構造は、第１実施例のリベット１の構造と同じである。よって、第２実施例のリベット２の構造における第１実施例のリベット１の構造と同じ構造の部材には、図７及び図８で説明した第１実施例のリベット１と同じ符号を付してその説明を省略し、構造が異なる部分だけを説明する。 (Rivets of the second embodiment)
In the rivet 1 of the first embodiment, as shown in FIG. 9A, the rear end portion 23 of the second tubular member 20 has a trumpet shape with a taper portion 23T, and the rear end of the pin member 40 is in the opening. The end 43 is exposed. On the other hand, as shown in FIGS. 9B and 10A, the rivet 2 of the second embodiment has the structure of the rear end portion 23 of the second cylindrical member 20A that is the rivet of the first embodiment. This is different from the structure of the rear end portion 23 of one second cylindrical member 20. That is, in the structure of the rivet 2 of the second embodiment shown in FIG. 10A, the structure below the line DD is the same as the structure of the rivet 1 of the first embodiment. Therefore, members having the same structure as that of the rivet 1 of the first embodiment in the structure of the rivet 2 of the second embodiment are denoted by the same reference numerals as those of the rivet 1 of the first embodiment described with reference to FIGS. The description thereof will be omitted, and only the parts with different structures will be described.

図９（ｂ）及び図１０（ａ）に示すように、第２筒状部材２０Ａの第２筒状部材２０Ａの後端部２３には円筒状に膨出された大径部２７が設けられており、大径部２７には第２筒状部材２０Ａの軸線に対して垂直な端面２７Ｆがある。そして、ピン部材４０の後端部４３は直角に折り曲げられ、折り曲げられた後端部４３が、第２筒状部材２０Ａの大径部２７の側面に設けられた開口２９から外に突出している。   As shown in FIGS. 9B and 10A, the rear end portion 23 of the second cylindrical member 20A of the second cylindrical member 20A is provided with a large-diameter portion 27 that bulges into a cylindrical shape. The large diameter portion 27 has an end face 27F perpendicular to the axis of the second tubular member 20A. The rear end portion 43 of the pin member 40 is bent at a right angle, and the bent rear end portion 43 protrudes outward from the opening 29 provided on the side surface of the large diameter portion 27 of the second cylindrical member 20A. .

（リベットを用いた板状部材の結合）
図１０（ａ）は第１実施例のリベット１を用いた場合の図７（ａ）に対応しており、板金６と回路基板７に設けられた取付孔６Ｈ，７Ｈに、第２実施例のリベット２の第１筒状部材１０が挿入された状態を示している。第２実施例のリベット２では、この状態で、第２筒状部材２０Ａの後端部２３にある大径部２７の端面２７Ｆを矢印Ｐで示すように押して、第２筒状部材２０Ａを第１筒状部材１０に押し込めば良い。 (Combination of plate members using rivets)
FIG. 10 (a) corresponds to FIG. 7 (a) when the rivet 1 of the first embodiment is used, and in the mounting holes 6H, 7H provided in the sheet metal 6 and the circuit board 7, the second embodiment. The state where the first cylindrical member 10 of the rivet 2 is inserted is shown. In the rivet 2 of the second embodiment, in this state, the end surface 27F of the large-diameter portion 27 at the rear end portion 23 of the second cylindrical member 20A is pushed as indicated by the arrow P, so that the second cylindrical member 20A is One cylindrical member 10 may be pushed.

図１０（ｂ）は第１実施例のリベット１を用いた場合の図７（ｃ）に対応しており、第２筒状部材２０Ａの大径部２７の下端部が第１筒状部材１０のフランジ１６に当接した状態を示している。この状態では、これ以上第２筒状部材２０Ａが押せなくなり、第２筒状部材２０Ａの先端周辺部２４が第１筒状部材１０の先端部１１から突出する。第２筒状部材２０Ａの先端周辺部２４が第１筒状部材１０の先端部１１から突出すると、ロック部材３０の脚部材３１を押すものがなくなり、脚部材３１は、板バネ３３の復元力によってロック部材収容孔２５から外部に突出する。   FIG. 10B corresponds to FIG. 7C when the rivet 1 of the first embodiment is used, and the lower end portion of the large diameter portion 27 of the second cylindrical member 20A is the first cylindrical member 10. The state which contact | abutted to the flange 16 of this is shown. In this state, the second cylindrical member 20 </ b> A can no longer be pressed, and the distal peripheral portion 24 of the second cylindrical member 20 </ b> A protrudes from the distal end portion 11 of the first cylindrical member 10. When the distal end peripheral portion 24 of the second cylindrical member 20A protrudes from the distal end portion 11 of the first cylindrical member 10, there is no thing pushing the leg member 31 of the lock member 30, and the leg member 31 has a restoring force of the leaf spring 33. Projecting outward from the lock member receiving hole 25.

図１０（ｂ）に示す状態では、第２筒状部材２０Ａの先端周辺部２４が第１筒状部材１０の先端部１１から突出しており、第１筒状部材１０の先端部１１から胴部１２が、スリット１５によって板金６の位置まで押し開かれる。この結果、板金６と回路基板７とが第１筒状部材１０の胴部１２によって締め付けられて固定される。また、第２筒状部材２０Ａの先端周辺部２４が第１筒状部材１０の先端部１１から突出した状態では、板ばね３３が湾曲状態から直線状になり、ロック部材３０の脚部材３１が、押し開かれた第１筒状部材１０の先端部１１にある貫通孔１４よりも外側に開く。このため、第２筒状部材２０Ａは第１筒状部材１０から引き抜くことができない。   In the state shown in FIG. 10B, the distal end peripheral portion 24 of the second cylindrical member 20 </ b> A protrudes from the distal end portion 11 of the first cylindrical member 10, and the trunk portion extends from the distal end portion 11 of the first cylindrical member 10. 12 is pushed open to the position of the sheet metal 6 by the slit 15. As a result, the sheet metal 6 and the circuit board 7 are fastened and fixed by the body 12 of the first cylindrical member 10. Further, in a state where the distal end peripheral portion 24 of the second cylindrical member 20A protrudes from the distal end portion 11 of the first cylindrical member 10, the leaf spring 33 is changed from a curved state to a linear shape, and the leg member 31 of the lock member 30 is The first cylindrical member 10 that has been pushed open is opened to the outside of the through hole 14 in the distal end portion 11. For this reason, the second cylindrical member 20 </ b> A cannot be pulled out from the first cylindrical member 10.

（リベットの取り外し）
次に、図１０（ｂ）に示した状態からリベット２を引き抜き、板金６と回路基板７との結合を解除する場合を説明する。リベット２を引き抜く場合は、図１０（ｃ）に示すように、第２筒状部材２０Ａの大径部２７の開口２９の内側に位置するピン部材４０の後端部４３を、矢印Ｑで示すように押してピン部材４０の後端部４３を開口２９の最下部まで移動させる。すると、ピン部材４０は拡径部２５Ｅ内にあるバネ４５を収縮させて、第２筒状部材２０Ａの内部通路２６を第２筒状部材２０Ａの先端部２１側に向かって移動する。 (Removal of rivets)
Next, the case where the rivet 2 is pulled out from the state shown in FIG. 10B and the coupling between the sheet metal 6 and the circuit board 7 is released will be described. When the rivet 2 is pulled out, the rear end portion 43 of the pin member 40 located inside the opening 29 of the large diameter portion 27 of the second cylindrical member 20A is indicated by an arrow Q as shown in FIG. The rear end portion 43 of the pin member 40 is moved to the lowermost portion of the opening 29 by pushing. Then, the pin member 40 contracts the spring 45 in the enlarged diameter portion 25E, and moves the internal passage 26 of the second cylindrical member 20A toward the distal end portion 21 side of the second cylindrical member 20A.

ピン部材４０の移動により、ピン部材４０の先端部４１が第２筒状部材２０Ａのロック部材収容孔２５の内部に突出し、板バネ３３を押して下に凸に湾曲させる。板バネ３３が下に凸に湾曲すると、ロック部材３０の脚部材３１がロック部材収容孔２５内に没入し、脚部材３１が第１筒状部材１０の先端部１１にある貫通孔１４と係合しなくなる。   By the movement of the pin member 40, the tip end portion 41 of the pin member 40 protrudes into the lock member accommodation hole 25 of the second cylindrical member 20A, and the leaf spring 33 is pushed to be bent downward. When the leaf spring 33 is curved downward, the leg member 31 of the lock member 30 is immersed in the lock member receiving hole 25, and the leg member 31 is engaged with the through hole 14 at the distal end portion 11 of the first tubular member 10. It will not match.

ピン部材４０を第２筒状部材２０の中に押し込んだ状態で、図１０（ｄ）に符号Ｒで示すように、第２筒状部材２０の大径部２７を第１筒状部材１０に対して引き上げる。この時、脚部材３１が没入している第２筒状部材２０Ａは、第１筒状部材１０の貫通孔１４によって係止されないので、第２筒状部材２０Ａは、第１筒状部材１０の先端部１１を縮めながら内部通路２６内を第１筒状部材１０の後端部１３側に移動できる。そして、第２筒状部材２０Ａの先端部２１が第１筒状部材１０の先端部１１の内部に入ると、ピン部材４０はバネ４５の付勢力で第２筒状部材２０Ａの内部通路２６内を自動的に第２筒状部材２０の後端部２３側に移動する。バネ係止フランジ４４が拡径部２６Ｅの端部に当接すると図１０（ｅ）に示す状態になる。   In a state where the pin member 40 is pushed into the second cylindrical member 20, the large-diameter portion 27 of the second cylindrical member 20 is formed on the first cylindrical member 10 as indicated by a symbol R in FIG. Pull up against it. At this time, since the second cylindrical member 20A in which the leg member 31 is immersed is not locked by the through hole 14 of the first cylindrical member 10, the second cylindrical member 20A is The inside of the internal passage 26 can be moved toward the rear end portion 13 of the first tubular member 10 while the front end portion 11 is contracted. When the distal end portion 21 of the second tubular member 20A enters the interior of the distal end portion 11 of the first tubular member 10, the pin member 40 is moved into the internal passage 26 of the second tubular member 20A by the biasing force of the spring 45. Is automatically moved to the rear end portion 23 side of the second tubular member 20. When the spring locking flange 44 comes into contact with the end of the enlarged diameter portion 26E, the state shown in FIG.

この後も第２筒状部材２０Ａを第１筒状部材１０から引き抜く方向に移動させると、ロック部材３０が第１筒状部材１０の通路１８に設けられた係止溝１７に対向した時点で、ロック部材３０の脚部材３１が板バネ３３の付勢力で回転して係止溝１７に係合する。このため、第２筒状部材２０Ａは、第１筒状部材１０に対してこれ以上引き抜けなくなり、第２筒状部材２０Ａを更に引っ張ると、第１筒状部材１０を板金６と回路基板７の取付孔６Ｈ，７Ｈから取り外すことができる。リベット２を以上のような操作で板金６と回路基板７の結合部から取り外した後は、リベット２は損傷していないので再使用が可能である。なお、第１筒状部材１０から第２筒状部材２０Ａだけを引き抜きたい場合は、図１０（ｆ）に示す状態で、再度ピン部材４０の後端部４３を開口２９の内部で第２筒状部材２０Ａの先端部２１側に移動させれば良い。   After that, when the second tubular member 20A is moved in the direction of being pulled out from the first tubular member 10, the lock member 30 faces the locking groove 17 provided in the passage 18 of the first tubular member 10. The leg member 31 of the lock member 30 is rotated by the urging force of the leaf spring 33 and engages with the locking groove 17. For this reason, the second cylindrical member 20A can no longer be pulled out with respect to the first cylindrical member 10, and when the second cylindrical member 20A is further pulled, the first cylindrical member 10 is removed from the sheet metal 6 and the circuit board 7. The mounting holes 6H and 7H can be removed. After the rivet 2 is removed from the joint between the sheet metal 6 and the circuit board 7 by the above operation, the rivet 2 is not damaged and can be reused. When only the second tubular member 20A is to be pulled out from the first tubular member 10, the rear end portion 43 of the pin member 40 is again placed inside the opening 29 in the state shown in FIG. What is necessary is just to move to the front-end | tip part 21 side of 20-A of shaped members.

図１１は第２実施例のリベット２の変形実施例のリベット２Ａを示すものである。変形実施例のリベット２Ａが、第２実施例のリベット２と異なる点は、ピン部材４０を元の位置に復帰させるバネ４５の位置である。第２実施例のリベット２では、第１実施例のリベット１と同様に、ピン部材４０を元の位置に復帰させるバネ４５は、第２筒状部材２０Ａの内部通路２６にある拡径部２６Ｅに収容されており、ピン部材４０のバネ係止フランジ４４に係合していた。   FIG. 11 shows a rivet 2A of a modified embodiment of the rivet 2 of the second embodiment. The rivet 2A of the modified embodiment is different from the rivet 2 of the second embodiment in the position of the spring 45 that returns the pin member 40 to the original position. In the rivet 2 of the second embodiment, similarly to the rivet 1 of the first embodiment, the spring 45 for returning the pin member 40 to the original position is the enlarged diameter portion 26E in the internal passage 26 of the second cylindrical member 20A. And is engaged with the spring locking flange 44 of the pin member 40.

一方、変形実施例のリベット２Ａでは、第２筒状部材２０Ｂの大径部２７の軸線方向の長さが延長され、開口２９内のピン部材４０の胴部４２にバネ４５が巻き付けられている。大径部２７の軸線方向の長さは、バネ４５が収縮した時の全長分だけ延長されている。変形実施例のリベット２Ａの動作は第２実施例のリベット２の動作と同じであるので、その説明を省略する。このように、ピン部材４０を元の位置に復帰させるバネ４５の位置、種類は特に限定されるものではない。バネ４５はスプリング以外にも、板バネやゴム部材でも良い。   On the other hand, in the rivet 2A of the modified embodiment, the axial length of the large diameter portion 27 of the second cylindrical member 20B is extended, and the spring 45 is wound around the body portion 42 of the pin member 40 in the opening 29. . The length of the large diameter portion 27 in the axial direction is extended by the entire length when the spring 45 contracts. Since the operation of the rivet 2A of the modified embodiment is the same as that of the rivet 2 of the second embodiment, the description thereof is omitted. Thus, the position and type of the spring 45 for returning the pin member 40 to the original position are not particularly limited. In addition to the spring, the spring 45 may be a plate spring or a rubber member.
