従来、グロメットとピンとから構成されたプッシュリベットが知られている(例えば特許文献1)。
上記した従来のプッシュリベットは、グロメットのフランジ部の底に、押し上げ突起を設けている(特許文献1の段落番号「0019」、段落番号「0026」、図2及び図3)。また、従来のプッシュリベットは、本止め状態においてピンを回転した際に、上記押し上げ突起に係合する引き上げ突起を、ピンの頭部に設けている(特許文献1の段落番号「0021」、段落番号「0026」、図2及び図10)。 Conventionally, a push rivet including a grommet and a pin is known (for example, Patent Document 1).
The above-described conventional push rivet is provided with a push-up protrusion at the bottom of the flange portion of the grommet (paragraph number “0019”, paragraph number “0026” in FIG. 2 and FIG. 3). Further, the conventional push rivet is provided with a lifting protrusion on the head of the pin that engages with the lifting protrusion when the pin is rotated in the fully-fastened state (paragraph number “0021” in Patent Document 1; paragraph Number “0026”, FIGS. 2 and 10).

The above-described conventional push rivet is provided with a push-up protrusion at the bottom of the flange portion of the grommet (paragraph number “0019”, paragraph number “0026” in FIG. 2 and FIG. 3). Further, the conventional push rivet is provided with a lifting protrusion on the head of the pin that engages with the lifting protrusion when the pin is rotated in the fully-fastened state (paragraph number “0021” in Patent Document 1; paragraph Number “0026”, FIGS. 2 and 10).
しかし、上記した従来のプッシュリベットは、本止め状態において、グロメットのフランジ部とピンの頭部とが密着するため、両者の間に泥水等が浸入してしまうと、外部に流れ落ち難く、又、内部で乾燥して硬化すると、両者が密着していまい、ピンの解除が困難になってしまうという問題点があった。
そこで、本発明は、上記した従来の技術の有する問題点に鑑みてなされたものであり、その目的とするところは、グロメットをピンに挿入した本止め状態において、グロメットのフランジ部とピンの頭部との間に生ずるクリアランスを通じて、泥砂や泥水等の異物を排出もしくは排水することができるようにしたものである。 However, since the conventional push rivet described above is in the final stop state, the flange part of the grommet and the head part of the pin are in close contact with each other, and if muddy water or the like enters between them, it is difficult to flow outside, When it dries and hardens inside, there is a problem that both of them are in close contact with each other and it becomes difficult to release the pin.
Accordingly, the present invention has been made in view of the above-described problems of the prior art, and the object of the present invention is to provide a flange portion of the grommet and the head of the pin in the fixed state where the grommet is inserted into the pin. The foreign matter such as mud sand and muddy water can be discharged or drained through the clearance generated between the two parts.

ガイド溝115は、図1、図9~11及び図14に示すように、角部112にそれぞれ形成され、フランジ部60の挿通孔61内に突出するガイド突起62にスライド可能にはまり合う。 The bulgingportion 91 of the flange portion 60 contacts the concave groove 111. However, when the shaft portion 110 is inserted into the hollow interior of the split leg portion 90 through the insertion hole 61 of the flange portion 60, the bulging portion 91 is notched 113. Abut. When the shaft portion 110 is inserted further deeper, the bulging portion 91 rides on the stepped portion 114, and the outer diameter of the divided leg portion 90 is increased. Further, when the shaft portion 110 is inserted, the bulging portion 91 that has been riding on the stepped portion 114 falls to the bottom of the recessed groove 111 that is lowered by one step, and at this time, a click feeling is generated, and the bulging portion 91 is Abutting on the stepped portion 114 that is raised by one step, the sliding of the shaft portion 110 in the removal direction is prevented.
(Guide groove 115)
As shown in FIGS. 1, 9 to 11, and 14, theguide grooves 115 are formed in the corner portions 112, respectively, and slidably fit into the guide protrusions 62 protruding into the insertion holes 61 of the flange portion 60.

For this reason, thepanel 20 and the component 30 are sandwiched and held between the four divided leg portions 90 having an enlarged diameter and the upper surface of the flange portion 60 of the grommet 40, and the component 30 is attached to the panel 20 via the push rivet 10. Fixed.
ピン50を挿入すると、その4個の凹溝111に、4個の分割脚部90の膨出部91がそれぞれ乗り上がり、パネル20の上方において、4個の分割脚部90の外径が拡径する。
このため、パネル20と部品30は、拡径した4個の分割脚部90と、グロメット40のフランジ部60の上面との間に挟み持たれ、部品30はプッシュリベット10を介してパネル20に固定される。 Thereafter, the
When the
For this reason, the
また、このとき、分割脚部90の膨出部91が、ピン50の軸部110の段差部114に乗り越え、一段低くなった凹溝111の底に落ち込み、このときクリック感が発生し、又、膨出部91は一段高くなった段差部114に当接し、軸部110の抜け方向のスライドが阻止され、ピン50がグロメット40に対して本止め状態にロックされる。
この本止め状態において、ピン50の頭部100は、図21~23に示すように、グロメット40のフランジ部60の突縁部64の内周側にスッポリとはまり込む。 At this time, the bulgingportion 91 of the split leg 90 gets over the stepped portion 114 of the shaft portion 110 of the pin 50 and falls to the bottom of the recessed groove 111 that is lowered by one step, and a click feeling is generated at this time. The bulging portion 91 comes into contact with the stepped portion 114 that is raised one step higher, so that the sliding of the shaft portion 110 in the removal direction is prevented, and the pin 50 is locked to the grommet 40 in the fully stopped state.
In this fully locked state, thehead portion 100 of the pin 50 snaps into the inner peripheral side of the protruding edge portion 64 of the flange portion 60 of the grommet 40 as shown in FIGS.
この本止め状態において、ピン50の頭部100は、図21~23に示すように、グロメット40のフランジ部60の突縁部64の内周側にスッポリとはまり込む。 At this time, the bulging
In this fully locked state, the
このとき、ピン50の頭部100の上面は、図22及び図23に示すように、フランジ部60の突部65の下面と当接し、ピン50の頭部100の上面とフランジ部60の下面との間に、クリアランス120が発生する。
このため、クリアランス120を通じて、泥砂や泥水等の異物を外側に向かって排出もしくは排水することができる。 At this time, as shown in FIGS. 22 and 23, the upper surface of thehead portion 100 of the pin 50 abuts on the lower surface of the protrusion 65 of the flange portion 60, and the upper surface of the head portion 100 of the pin 50 and the lower surface of the flange portion 60. Clearance 120 occurs between the two.
For this reason, foreign substances such as mud sand and muddy water can be discharged or drained to the outside through theclearance 120.
このため、クリアランス120を通じて、泥砂や泥水等の異物を外側に向かって排出もしくは排水することができる。 At this time, as shown in FIGS. 22 and 23, the upper surface of the
For this reason, foreign substances such as mud sand and muddy water can be discharged or drained to the outside through the
その結果、ピン50の頭部100の上面とフランジ部60の下面との間に、泥砂等の異物が堆積し難くなる。
(部品30の取り外し)
部品30を取り外す際には、グロメット40のフランジ部60の差込溝63から、図示しないが、マイナス・ドライバー等の治具を差し込み、ピン50の頭部100をフランジ部60から離隔する方向に移動すれば良い。 As a result, foreign matter such as mud sand hardly accumulates between the upper surface of thehead portion 100 of the pin 50 and the lower surface of the flange portion 60.
(Removal of part 30)
When removing thepart 30, insert a jig such as a flathead screwdriver (not shown) from the insertion groove 63 of the flange part 60 of the grommet 40 in a direction to separate the head part 100 of the pin 50 from the flange part 60. Just move.

When removing the
ピン50の頭部100をフランジ部60から離隔する方向に移動すると、ピン50の軸部110が、フランジ部60の挿通孔61から抜ける方向に移動し、このとき、分割脚部90の膨出部91が、ピン50の軸部110の凹溝111より一段高くなった段差部114に乗り上がり、ロック状態が解除される。
その後、ピン50の頭部100を持って、その軸部110をフランジ部60の挿通孔61から抜ける方向に移動すると、軸部110の凹溝111に乗り上がっていた分割脚部90の膨出部91が、当該凹溝111から離隔する。このため、分割脚部90は、自身の弾性に加え、連結脚部80の弾性により、元の外径に縮径する。 When thehead portion 100 of the pin 50 is moved away from the flange portion 60, the shaft portion 110 of the pin 50 moves away from the insertion hole 61 of the flange portion 60. At this time, the split leg portion 90 bulges. The portion 91 rides on the stepped portion 114 that is one step higher than the recessed groove 111 of the shaft portion 110 of the pin 50, and the locked state is released.
After that, when holding thehead portion 100 of the pin 50 and moving the shaft portion 110 in a direction to come out from the insertion hole 61 of the flange portion 60, the split leg portion 90 that has ridden in the groove 111 of the shaft portion 110 bulges. The portion 91 is separated from the concave groove 111. For this reason, the split leg 90 is reduced in diameter to the original outer diameter by the elasticity of the connecting leg 80 in addition to its own elasticity.
その後、ピン50の頭部100を持って、その軸部110をフランジ部60の挿通孔61から抜ける方向に移動すると、軸部110の凹溝111に乗り上がっていた分割脚部90の膨出部91が、当該凹溝111から離隔する。このため、分割脚部90は、自身の弾性に加え、連結脚部80の弾性により、元の外径に縮径する。 When the
After that, when holding the
このため、グロメット40の支持脚70を、パネル20の貫通孔21から抜くことが可能となり、部品30を貫通孔21から取り外すことができる。
なお、治具を使用してロックを解除したが、治具を使用せずに、指の爪を差込溝63に差し込んでロックを解除することも可能である。 Therefore, thesupport leg 70 of the grommet 40 can be removed from the through hole 21 of the panel 20, and the component 30 can be removed from the through hole 21.
Although the lock is released using a jig, it is also possible to release the lock by inserting a fingernail into theinsertion groove 63 without using a jig.
