FIG. 8 is an explanatory view showing a state in which the operation member in the fixing tool is raised, and FIG. 8 is an explanatory view showing a state in which the operation member in the fixing tool is tilted halfway. Here, the fixture 10 is partially inserted into the fixing holes 11 and 12 provided in the fixed member P and the fixing member S, respectively, and fixes the fixed member P to the fixing member S. A grommet 14 having a leg portion 13 partially inserted through the fixing holes 11 and 12, and a grommet that is movably inserted into the grommet and can be provided in the leg portion 13 to hold the leg piece 13a in an expanded state. A pin member 15 and an operation member 17 having a pressing piece 16 that is pivotally supported by the grommet 14 and moves the pin member 15 in the grommet are provided.

グロメット１４は、略角筒状をしており、上端が開口するとともに、左右に支持軸１８、１８が立設されている。また、上端から所定の位置まで、ピン部材１５を案内するための一対の案内溝１９、２０が形成されている。更に、グロメット１４は、外周の一部に被固定部材Ｐに形成された位置決め凹部１１ａと嵌合する位置決め突起２１を有している。グロメット１４の脚部１３には、二方向に脚片１３ａが弾性変形可能に形成されている。   The grommet 14 has a substantially rectangular tube shape, and an upper end is opened, and support shafts 18 and 18 are erected on the left and right. A pair of guide grooves 19 and 20 for guiding the pin member 15 is formed from the upper end to a predetermined position. Further, the grommet 14 has a positioning protrusion 21 that fits with a positioning recess 11 a formed in the fixed member P on a part of the outer periphery. A leg piece 13a is formed on the leg portion 13 of the grommet 14 so as to be elastically deformable in two directions.

ピン部材１５は、前記グロメット１４の角筒内を移動可能な角断面を有するとともに、頂部に操作部材１７に形成された押圧片１６の先端を両側から支承するための小突起２２、２２が形成されており、操作部材１７の起立状態を維持することができる。また、ピン部材１５には、規制突起２３、２４が側方に突設されており、前記グロメット１４に形成された案内溝１９、２０内を移動することによりピン部材１５の下降寸法を規制している。更に、図４、図６に示すようにピン部材１５の下端部１５ａは、断面が紡錘形に形成されるとともに、脚片１３ａと当接する部位の先端近傍のアンダーカット部１５ｂが薄く、上に向かうに従って徐々に厚く形成されている。したがって、グロメット１４内のピン部材１５を押し下げると、脚部１３の脚片１３ａが外方に膨出する。   The pin member 15 has a square cross section that can move in the square tube of the grommet 14, and small protrusions 22, 22 for supporting the tip of the pressing piece 16 formed on the operation member 17 from both sides at the top. Thus, the operation member 17 can be kept upright. The pin member 15 is provided with restricting projections 23 and 24 projecting laterally. The pin member 15 moves in the guide grooves 19 and 20 formed in the grommet 14 to restrict the descending dimension of the pin member 15. ing. Further, as shown in FIGS. 4 and 6, the lower end portion 15a of the pin member 15 is formed in a spindle shape in cross section, and the undercut portion 15b in the vicinity of the tip of the portion in contact with the leg piece 13a is thin and faces upward. The thickness is gradually increased. Therefore, when the pin member 15 in the grommet 14 is pushed down, the leg piece 13a of the leg portion 13 bulges outward.

操作部材１７は、支持軸１８に回動可能に軸支されるための一対の係合孔２５と、係合孔２５の外縁に形成され、操作部材１７を倒した際に被固定部材Ｐ若しくは固定部材Ｓと当接する一対のカム部２６と、前記カム部２６に隣接するとともに対向配置された略円板状のガイド部２７とを備えている。また、本体では、係合孔２５は、グロメット１４の支持軸径より大きく形成されている。したがって、この径の差によって操作部材１７の起立の保持およびグロメット１４を引き上げる軸方向の力の保持等が可能となる。更に、操作部材１７は、倒した際にグロメット頂部と嵌合する嵌合溝１７ａを押圧片１６の左右に有している。また、押圧片１６は、操作部材１７の中央に形成されており、操作部材１７の起立時にグロメット内に挿通されピン部材１５を上昇させ、その頂部が当接することにより起立状態を維持できる。また、操作部材１７を回動させた場合には、ピン部材１５をグロメット内で下降移動させ、脚片１３ａを膨出させる。   The operation member 17 is formed at a pair of engagement holes 25 to be pivotally supported by the support shaft 18 and an outer edge of the engagement hole 25, and when the operation member 17 is tilted, A pair of cam portions 26 that come into contact with the fixing member S, and a substantially disk-shaped guide portion 27 that is adjacent to the cam portion 26 and disposed opposite thereto are provided. Further, in the main body, the engagement hole 25 is formed larger than the support shaft diameter of the grommet 14. Therefore, the operation member 17 can be held up and the axial force for lifting the grommet 14 can be held by the difference in diameter. Furthermore, the operating member 17 has fitting grooves 17a on the left and right sides of the pressing piece 16 that are fitted to the top of the grommet when it is tilted. Further, the pressing piece 16 is formed at the center of the operation member 17 and is inserted into the grommet when the operation member 17 stands up to raise the pin member 15, and the top portion abuts to maintain the standing state. When the operation member 17 is rotated, the pin member 15 is moved down in the grommet, and the leg piece 13a is bulged.

カム部２６の外周形状は、操作部材１７が起立状態を維持して被固定部材Ｐと当接する平坦部２６ａと操作部材１７が回動の途中で被固定部材Ｐと当接する突起部２６ｂと、操作部材１７がロック状態で被固定部材Ｐと当接する円弧部２６ｃから構成されている。したがって、操作部材１７は、被固定部材Ｐと平坦部２６ａで当接することで起立状態を維持し易くなる。また、ロック状態では、突起部２６ｂを乗り越えた後に、円弧部２６ｃで被固定部材Ｐと当接するので、元に戻り難い。   The outer peripheral shape of the cam portion 26 includes a flat portion 26a in which the operation member 17 maintains an upright state and comes into contact with the fixed member P, a protruding portion 26b in which the operation member 17 comes into contact with the fixed member P during rotation, The operation member 17 is configured by an arc portion 26c that contacts the fixed member P in a locked state. Therefore, the operating member 17 is easily maintained in an upright state by contacting the fixed member P with the flat portion 26a. Further, in the locked state, after getting over the protruding portion 26b, the arc portion 26c comes into contact with the fixed member P, so that it is difficult to return to the original state.

また、図６に示すように被固定部材Ｐに形成された固定孔１２は、脚部１３の挿通可能な形状、例えば、長方形をしている。また、固定部材Ｓに形成された固定孔１１は、操作部材１７の係合孔２５の外縁に形成されたガイド部２７が嵌合されるが、ガイド部２７に隣接形成されたカム部２６が挿入されない寸法である。つまり、カム部２６とガイド部２７は、フランジ付きのレールのように操作部材１７の左右に配置されており、操作部材１７の偏りや変形を自動的に修正する作用を発揮する。   Further, as shown in FIG. 6, the fixing hole 12 formed in the fixed member P has a shape into which the leg portion 13 can be inserted, for example, a rectangle. Further, the fixing hole 11 formed in the fixing member S is fitted with a guide portion 27 formed on the outer edge of the engaging hole 25 of the operation member 17, but the cam portion 26 formed adjacent to the guide portion 27 is provided. The dimension is not inserted. That is, the cam portion 26 and the guide portion 27 are arranged on the left and right sides of the operation member 17 like a rail with a flange, and exert an action of automatically correcting the bias and deformation of the operation member 17.

次に、以上の様に構成された固定具１０の操作手順について、図９〜図１１にしたがって説明する。先ず、図１、９に示すようにピン部材１５が上に上昇し、頂部の小突起２２が起立状態の操作部材１７の押圧片１６を両側から保持している固定具１０の脚部１３を被固定部材Ｐ及び固定部材Ｓに形成された固定孔１１、１２に挿通する。また、位置決め突起２１は、固定孔１１の位置決め凹部１１ａに嵌合するようにする。この時、カム部２６の平坦部２６ａが被固定部材Ｐと当接しており、支持軸１８の軸芯から被固定部材表面までの距離はＸであり、ガイド部２７は固定孔１１の縁部に挿入されている。   Next, the operation procedure of the fixture 10 configured as described above will be described with reference to FIGS. First, as shown in FIGS. 1 and 9, the pin member 15 rises upward, and the leg portion 13 of the fixture 10 holding the pressing piece 16 of the operating member 17 in the upright state with the small protrusion 22 on the top is held. The fixing member P and the fixing member S are inserted into fixing holes 11 and 12. The positioning protrusion 21 is fitted into the positioning recess 11 a of the fixing hole 11. At this time, the flat portion 26 a of the cam portion 26 is in contact with the fixed member P, the distance from the axis of the support shaft 18 to the surface of the fixed member is X, and the guide portion 27 is the edge of the fixing hole 11. Has been inserted.

次に、図１０に示すように操作部材１７を途中まで回動すると、カム部２６の突起部２６ｂが被固定部材と当接し、支持軸１８の軸芯から被固定部材表面までの距離はＹとなる。距離Ｙ＞Ｘである。また、押圧片１６は、ピン部材１５の頭部を押し下げてゆく。ピン部材１５が下降すると、脚片１３ａが徐々に膨出する。   Next, as shown in FIG. 10, when the operation member 17 is rotated halfway, the projection 26b of the cam portion 26 comes into contact with the fixed member, and the distance from the axis of the support shaft 18 to the surface of the fixed member is Y. It becomes. The distance Y> X. Further, the pressing piece 16 pushes down the head of the pin member 15. When the pin member 15 descends, the leg piece 13a gradually bulges.

操作部材１７を更に回動して略水平になるまで倒すと、図１１に示すようにカム部は、突起部２６ｂを乗り越えて、円弧部２６ｃで被固定部材Ｐと当接する。この時、グロメット１４は上方向に引き上げられるとともに、ピン部材１５が下降して脚片１３ａを外周方向へ膨出させる。また、支持軸１８の軸芯から被固定部材表面までの距離はＺとなり、距離Ｙ＞Ｚである。脚片１３ａが外周方向へ膨出することにより、脚部１３は固定孔１２から抜けることなく、被固定部材ｐに固定部材Ｓを固定することができる。更に、操作部材１７を倒した際にグロメット頂部と嵌合溝１７ａが嵌合するので、より強固にグロメット１４と操作部材１７のセンタリング作用を促進することができる。また、このように操作部材１７を回動するのみで、固定できるので、裏面に手を廻す必要もないので作業性を向上することができる。また、部品点数の削減を図ることができる。更に、係合孔２５は、グロメット１４の支持軸径より大きく形成されているので、操作部材１７を倒立させた場合、係合孔２５の位置をオフセットさせることができ、成型時の支持軸１８と係合孔２５のガタ付きを抑制することができる。   When the operation member 17 is further rotated and tilted until it becomes substantially horizontal, as shown in FIG. 11, the cam portion gets over the protruding portion 26b and comes into contact with the fixed member P at the arc portion 26c. At this time, the grommet 14 is pulled upward and the pin member 15 is lowered to bulge the leg piece 13a in the outer peripheral direction. Further, the distance from the axis of the support shaft 18 to the surface of the fixed member is Z, and the distance Y> Z. When the leg piece 13a bulges in the outer peripheral direction, the leg portion 13 can fix the fixing member S to the fixed member p without coming out of the fixing hole 12. Furthermore, since the top of the grommet and the fitting groove 17a are fitted when the operating member 17 is tilted, the centering action of the grommet 14 and the operating member 17 can be more strongly promoted. Further, since the operation member 17 can be fixed only by rotating in this way, it is not necessary to turn the hand to the back surface, so that workability can be improved. In addition, the number of parts can be reduced. Further, since the engagement hole 25 is formed larger than the support shaft diameter of the grommet 14, when the operation member 17 is inverted, the position of the engagement hole 25 can be offset, and the support shaft 18 at the time of molding is formed. The backlash of the engagement hole 25 can be suppressed.

また、固定を解除する場合は、ピン部材１５を押し込んでいた操作部材１７を起立させるとともに、ピン部材１５を引き上げると云う、２段階動作によって可能である。ピン部材１５の引き上げは、規制突起２４或いは規制突起２３をドライバー等の先端で引き上げることにより可能である。また、ロック解除動作も裏面に手を廻すことなく、一側面から操作できる。
このようにロック解除動作が２段階であることにより、安全性が向上するとともに、固定具１０の繰り返し利用ができる。 In addition, the fixing can be released by a two-stage operation in which the operation member 17 that has pushed the pin member 15 is raised and the pin member 15 is pulled up. The pin member 15 can be pulled up by pulling up the restricting protrusion 24 or the restricting protrusion 23 with the tip of a driver or the like. Also, the unlocking operation can be performed from one side without turning the back.
As described above, since the unlocking operation is in two stages, safety is improved and the fixture 10 can be used repeatedly.

このように構成された固定具１０を使用してハイマウントブレーキランプ２８を車のボディパネル２９に取付ける例を図１２、１３に示す。先ず、ボディパネル２９にハイマウントブレーキランプ２８を取付けるとともに固定具１０を固定孔に挿入して仮締結する。仮締結後、固定具１０の操作部材１７を倒すことによりワンタッチで固定することができる。したがって、取付け作業の効率化が図れる。また、ハイマウントブレーキランプ２８を取り外す場合には、操作部材１７を引き起こすとともに、ドライバー等でピン部材１５を引き上げることで、容易に取り外すことができる。   12 and 13 show an example in which the high-mount brake lamp 28 is attached to the vehicle body panel 29 using the fixture 10 configured as described above. First, the high mount brake lamp 28 is attached to the body panel 29 and the fixture 10 is inserted into the fixing hole and temporarily tightened. After temporary fastening, the operation member 17 of the fixture 10 can be tilted to fix it with one touch. Therefore, the efficiency of the mounting work can be improved. Further, when removing the high-mount brake lamp 28, the operation member 17 is caused, and the pin member 15 can be easily removed by pulling up the pin member 15 with a screwdriver or the like.

なお、以上の実施の形態では、押圧片１６がピン部材１５の頭部を押し下げてゆくと脚片１３ａが徐々に膨出する構成としたが、脚片が予め膨出しており、ピン部材が脚片の後退を許可或いは阻止する構成としてもよい。また、本発明は上述の実施例に限定されることなく、特許請求の範囲の記載に基づいて種々の設計変更が可能である。   In the above embodiment, the leg piece 13a gradually bulges when the pressing piece 16 pushes down the head of the pin member 15. However, the leg piece bulges in advance, and the pin member It is good also as a structure which permits or prevents retraction of a leg piece. The present invention is not limited to the above-described embodiments, and various design changes can be made based on the description of the scope of claims.
