Description

この発明は、車載機器を車両に固定するネジ構造に関するものである。   The present invention relates to a screw structure for fixing an in-vehicle device to a vehicle.

ディスプレイなどの車載機器を車両のダッシュボードなどに固定する場合、一般的にネジが使用されている。例えば図１４に示すように、車両側に固定された意匠パネル２００にディスプレイ１００を取り付ける場合、作業者は、先ずディスプレイ１００を矢印Ｘ１の方向にスライドさせて筐体１０１を意匠パネル２００の凹部２０１に挿入する。図１５に示すようにディスプレイ１００の挿入が完了したら、作業者は、図１６に示すように意匠パネル２００の上面に設けられた貫通穴２０２にネジ２０３をセットして締め付ける。
ネジ２０３が締結されると、図１７に示すように、ネジ２０３によって筐体１０１の被締結部１０２が意匠パネル２００に固定された状態になる。In general, a screw is used to fix an in-vehicle device such as a display to a dashboard of a vehicle. For example, as shown in FIG. 14, when the display 100 is attached to the design panel 200 fixed to the vehicle side, the operator first slides the display 100 in the direction of the arrow X1 to place the housing 101 in the recess 201 of the design panel 200. Insert into. When the insertion of the display 100 is completed as shown in FIG. 15, the operator sets and tightens the screws 203 in the through holes 202 provided on the upper surface of the design panel 200 as shown in FIG.
When the screw 203 is fastened, as shown in FIG. 17, the fastened portion 102 of the housing 101 is fixed to the design panel 200 by the screw 203.

図１４〜図１７に示したディスプレイ１００を意匠パネル２００から取り外す場合、作業者がネジ２０３を緩め、矢印Ｘ１とは反対の方向にディスプレイ１００をスライドさせて、筐体１０１を意匠パネル２００の凹部２０１から外す。このとき、図１８に示すようにネジ２０３の軸先端にはネジ山が刻まれていないので、ネジ２０３を緩めても軸先端の不完全ネジ部２０３ａが車両側ネジ穴２０４内に残ってしまう。この状態でディスプレイ１００を矢印Ｘ２の方向に抜こうとしても、ネジ２０３が車両側ネジ穴２０４と干渉するため抜くことができない。   When the display 100 shown in FIGS. 14 to 17 is removed from the design panel 200, the operator loosens the screw 203 and slides the display 100 in the direction opposite to the arrow X <b> 1, so that the housing 101 is recessed in the design panel 200. Remove from 201. At this time, as shown in FIG. 18, no screw thread is cut on the shaft tip of the screw 203, so that the incomplete screw portion 203 a at the shaft tip remains in the vehicle-side screw hole 204 even if the screw 203 is loosened. . Even if the display 100 is to be pulled out in the direction of the arrow X2 in this state, it cannot be pulled out because the screw 203 interferes with the vehicle-side screw hole 204.

例えば特許文献１では、上述したような取り付け作業において、ネジをネジ穴にセットする手間を軽減するためにネジを仮固定する手段が提案されているが、取り外し作業においてネジとネジ穴の干渉を回避するための手段は無い。   For example, Patent Document 1 proposes a means for temporarily fixing a screw in order to reduce the trouble of setting the screw in the screw hole in the above-described attachment work. However, in the removal work, interference between the screw and the screw hole is proposed. There is no way to avoid it.

実施の形態１．
図１は、実施の形態１に係るネジ構造１０の構成を示す断面図であり、図１（ａ）はネジ１１を締結した状態、図１（ｂ）および図１（ｃ）はネジ１１を緩めている途中の状態、図１（ｄ）はネジ１１を完全に緩めた状態である。図２は、ネジ構造１０を備えたディスプレイ１００と意匠パネル２００の断面図であり、図１４〜図１８と同一または相当の部分については同一の符号を付し説明を省略する。Hereinafter, in order to explain the present invention in more detail, modes for carrying out the present invention will be described with reference to the accompanying drawings.
Embodiment 1 FIG.
FIG. 1 is a cross-sectional view showing a configuration of a screw structure 10 according to the first embodiment. FIG. 1A shows a state in which a screw 11 is fastened, and FIGS. 1B and 1C show a screw 11. FIG. 1 (d) shows a state in which the screw 11 is completely loosened. FIG. 2 is a cross-sectional view of the display 100 and the design panel 200 provided with the screw structure 10. The same or corresponding parts as those in FIGS. 14 to 18 are denoted by the same reference numerals and description thereof is omitted.

実施の形態１に係るネジ構造１０では、１本のネジ１１に径の異なる２種のオネジ部が形成されている。小さい径ｄ１３の第１オネジ部１３は、車両側の意匠パネル２００に形成された車両側ネジ穴１７の第１メネジ部１８に螺合する。大きい径ｄ１２の第２オネジ部１２は、ディスプレイ１００の筐体１０１に形成された被締結部１４の第２メネジ部１５に螺合する。被締結部１４の底面に開口した貫通穴１６は、ネジ１１の第２オネジ部１２より小径、かつ第１オネジ部１３より大径であり、貫通穴１６の周縁部がネジ１１の座面になる。   In the screw structure 10 according to Embodiment 1, two types of male screw portions having different diameters are formed on one screw 11. The first male screw portion 13 having a small diameter d13 is screwed into the first female screw portion 18 of the vehicle side screw hole 17 formed in the design panel 200 on the vehicle side. The second male screw portion 12 having a large diameter d12 is screwed into the second female screw portion 15 of the fastened portion 14 formed in the housing 101 of the display 100. The through hole 16 opened on the bottom surface of the fastened portion 14 is smaller in diameter than the second male screw portion 12 of the screw 11 and larger in diameter than the first male screw portion 13, and the peripheral portion of the through hole 16 is a seating surface of the screw 11. Become.

図１（ａ）に示すようにネジ１１が締結された状態では、被締結部１４の第２メネジ部１５は使用されず、車両側ネジ穴１７の第１メネジ部１８とネジ１１の第１オネジ部１３が使用される。被締結部１４は、車両側ネジ穴１７の第１メネジ部１８とネジ１１の第１オネジ部１３との螺合により、車両側に固定される。   As shown in FIG. 1A, in the state where the screw 11 is fastened, the second female screw portion 15 of the fastened portion 14 is not used, and the first female screw portion 18 of the vehicle-side screw hole 17 and the first of the screw 11 are used. The male screw part 13 is used. The fastened portion 14 is fixed to the vehicle side by screwing the first female screw portion 18 of the vehicle-side screw hole 17 and the first male screw portion 13 of the screw 11.

ネジ１１を緩める際、ネジ１１が回転すると、図１（ｂ）に示すように車両側ネジ穴１７の第１メネジ部１８とネジ１１の第１オネジ部１３との螺合によって、ネジ１１が矢印Ｙ１の方向（つまり、車両側ネジ穴１７の軸方向）に移動し、ネジ１１が車両側ネジ穴１７から外れていく。このとき、ある程度ネジ１１が車両側ネジ穴１７から外れたところで、被締結部１４の第２メネジ部１５とネジ１１の第２オネジ部１２とが螺合する。   When the screw 11 is loosened when the screw 11 is loosened, the screw 11 is screwed by the first female screw portion 18 of the vehicle-side screw hole 17 and the first male screw portion 13 of the screw 11 as shown in FIG. Moving in the direction of the arrow Y1 (that is, the axial direction of the vehicle-side screw hole 17), the screw 11 is removed from the vehicle-side screw hole 17. At this time, when the screw 11 is removed from the vehicle-side screw hole 17 to some extent, the second female screw portion 15 of the fastened portion 14 and the second male screw portion 12 of the screw 11 are screwed together.

図１（ｃ）に示すように、しばらくの間、車両側ネジ穴１７の第１メネジ部１８とネジ１１の第１オネジ部１３とが螺合しつつ、被締結部１４の第２メネジ部１５とネジ１１の第２オネジ部１２とが螺合している状態が続く。やがて、車両側ネジ穴１７の第１メネジ部１８とネジ１１の第１オネジ部１３との螺合が外れ、被締結部１４の第２メネジ部１５とネジ１１の第２オネジ部１２との螺合だけで、ネジ１１が矢印Ｙ１の方向に移動していく。   As shown in FIG. 1 (c), the first female screw portion 18 of the vehicle-side screw hole 17 and the first male screw portion 13 of the screw 11 are screwed together for a while, and the second female screw portion of the fastened portion 14 is engaged. 15 and the second male screw portion 12 of the screw 11 continue to be screwed together. Eventually, the first female screw portion 18 of the vehicle-side screw hole 17 and the first male screw portion 13 of the screw 11 are disengaged, and the second female screw portion 15 of the fastened portion 14 and the second male screw portion 12 of the screw 11 are connected. Only by screwing, the screw 11 moves in the direction of the arrow Y1.

最後に、図１（ｄ）で示すようにネジ１１が車両側ネジ穴１７から完全に外れた状態になる。このとき、ネジ１１の第２オネジ部１２が被締結部１４の第２メネジ部１５に螺合しているので、ネジ１１が被締結部１４に取り付いた状態になる。なお、第２メネジ部１５を形成する高さ位置は、第２メネジ部１５にネジ１１の第２オネジ部１２が螺合している状態でネジ１１が車両側ネジ穴１７から完全に外れるような高さ位置とする。   Finally, as shown in FIG. 1 (d), the screw 11 is completely removed from the vehicle-side screw hole 17. At this time, since the second male screw portion 12 of the screw 11 is screwed into the second female screw portion 15 of the fastened portion 14, the screw 11 is attached to the fastened portion 14. The height of the second female screw portion 15 is such that the screw 11 is completely removed from the vehicle-side screw hole 17 in a state where the second male screw portion 12 of the screw 11 is screwed to the second female screw portion 15. It should be a high position.

従って、図３に示すように被締結部１４が矢印Ｘ２の方向（つまり、車両側ネジ穴１７の軸方向と直交する方向）にスライドするとき、ネジ１１と車両側ネジ穴１７とが干渉しないので、ディスプレイ１００を矢印Ｘ２の方向にスライドさせて意匠パネル２００から取り外し可能である。一方、第２メネジ部１５が無い場合は、図１８で説明したように不完全ネジ部２０３ａが車両側ネジ穴２０４内に残った状態になるため、ディスプレイ１００をスライドさせることができない。
この考え方は、以降の実施の形態２，３についても同様である。Therefore, as shown in FIG. 3, when the fastened portion 14 slides in the direction of the arrow X2 (that is, the direction orthogonal to the axial direction of the vehicle-side screw hole 17), the screw 11 and the vehicle-side screw hole 17 do not interfere with each other. Therefore, the display 100 can be detached from the design panel 200 by sliding in the direction of the arrow X2. On the other hand, when the second female screw portion 15 is not provided, the display 100 cannot be slid because the incomplete screw portion 203a remains in the vehicle-side screw hole 204 as described with reference to FIG.
This concept is the same for the following second and third embodiments.

なお、ネジ１１にタッピングネジを使用する場合は、第２メネジ部１５と第１メネジ部１８の事前のネジ切りは不要である。
また、被締結部１４の内壁全周にわたって第２メネジ部１５を形成してもよいし、周方向に途切れ途切れに第２メネジ部１５を形成してもよい。
さらに、図４に示すように、第２メネジ部１５の下端部に傾斜面状のガイド部１９を形成してもよい。ネジ１１を緩める際、ネジ１１の上端部がガイド部１９に沿って矢印Ｙ１の方向に移動することで、ネジ１１の第２オネジ部１２と第２メネジ部１５との螺合がスムーズになる。In addition, when using a tapping screw for the screw 11, the prior thread cutting of the 2nd female thread part 15 and the 1st female thread part 18 is unnecessary.
Moreover, the 2nd female thread part 15 may be formed over the inner wall whole periphery of the to-be-fastened part 14, and the 2nd female thread part 15 may be formed in the circumferential direction discontinuously.
Further, as shown in FIG. 4, an inclined surface-shaped guide portion 19 may be formed at the lower end portion of the second female screw portion 15. When the screw 11 is loosened, the upper end portion of the screw 11 moves along the guide portion 19 in the direction of the arrow Y1, so that the second male screw portion 12 and the second female screw portion 15 of the screw 11 are smoothly engaged. .

以上より、実施の形態１に係るネジ構造１０において、ネジ１１は、第１オネジ部１３と当該第１オネジ部１３より大径の第２オネジ部１２とを有し、車両側ネジ穴１７は、ネジ１１の第１オネジ部１３と螺合して被締結部１４を車両側の意匠パネル２００に固定する第１メネジ部１８を有し、被締結部１４は、ディスプレイ１００を取り外す場合にネジ１１の第２オネジ部１２と螺合してネジ１１を車両側ネジ穴１７から外れた状態で保持する第２メネジ部１５を有する構成にした。これにより、被締結部１４がスライドするときにネジ１１が車両側ネジ穴１７に干渉しないので、ネジ１１を緩めるだけでディスプレイ１００を意匠パネル２００から取り外し可能な状態にすることができる。   As described above, in the screw structure 10 according to the first embodiment, the screw 11 includes the first male screw portion 13 and the second male screw portion 12 having a larger diameter than the first male screw portion 13, and the vehicle-side screw hole 17 is The first male screw part 13 of the screw 11 is screwed to fix the fastened part 14 to the design panel 200 on the vehicle side, and the fastened part 14 is a screw when the display 100 is removed. 11, the second female screw portion 12 and the second female screw portion 15 for holding the screw 11 in a state of being removed from the vehicle-side screw hole 17. Thereby, since the screw 11 does not interfere with the vehicle-side screw hole 17 when the fastened portion 14 slides, the display 100 can be removed from the design panel 200 only by loosening the screw 11.

実施の形態２．
図５は、実施の形態２に係るネジ構造２０の構成を示す断面図であり、図５（ａ）はネジ２１を締結する前の状態、図５（ｂ）はネジ２１を締結した状態、図５（ｃ）はネジ２１を完全に緩めた状態である。このネジ構造２０は、図２に示したネジ構造１０の代わりに、ディスプレイ１００の筐体１０１と意匠パネル２００とに形成されるものである。また、ディスプレイ１００と意匠パネル２００の基本的な構成は、図２および図１４〜図１８と同じである。Embodiment 2. FIG.
FIG. 5 is a cross-sectional view showing the configuration of the screw structure 20 according to the second embodiment. FIG. 5A is a state before the screw 21 is fastened, FIG. 5B is a state where the screw 21 is fastened, FIG. 5C shows a state in which the screw 21 is completely loosened. The screw structure 20 is formed on the housing 101 of the display 100 and the design panel 200 instead of the screw structure 10 shown in FIG. The basic configurations of the display 100 and the design panel 200 are the same as those in FIGS. 2 and 14 to 18.

実施の形態２に係るネジ構造２０では、ネジ２１は、頭部２２とオネジ部２３とを有する一般的な形状である。オネジ部２３は、車両側の意匠パネル２００に形成された車両側ネジ穴２７のメネジ部２８に螺合する。   In the screw structure 20 according to the second embodiment, the screw 21 has a general shape having a head portion 22 and a male screw portion 23. The male screw portion 23 is screwed into a female screw portion 28 of a vehicle-side screw hole 27 formed in the design panel 200 on the vehicle side.

ディスプレイ１００の筐体１０１に形成された被締結部２４には、ネジ２１のオネジ部２３を貫通させる貫通穴２５と、この貫通穴２５の周縁部から内側に向かって突出した薄い弁２６とが形成されている。弁２６は、樹脂材または金属材などで構成されて弾性力を有し、ネジ２１を引っ掛けて保持する機能をもつ。図示例では、弁２６の厚みが被締結部２４の厚みより薄いが、上記の機能が満足できるならば被締結部２４と同じ厚みかそれ以上でもよい。また、被締結部２４と弁２６とは基本的には一体構造になっているが、別部品にしても問題は無い。   The fastened portion 24 formed in the housing 101 of the display 100 includes a through hole 25 that allows the male screw portion 23 of the screw 21 to pass therethrough and a thin valve 26 that protrudes inward from the peripheral portion of the through hole 25. Is formed. The valve 26 is made of a resin material or a metal material, has an elastic force, and has a function of hooking and holding the screw 21. In the illustrated example, the thickness of the valve 26 is thinner than the thickness of the fastened portion 24, but it may be equal to or greater than that of the fastened portion 24 as long as the above function can be satisfied. Moreover, although the to-be-fastened part 24 and the valve 26 are fundamentally integral structure, even if it is a separate component, there is no problem.

図６および図７は、弁２６を図５（ａ）の矢印Ｙ２の方向から見た平面図である。図６では、１個の貫通穴２５に対して３個の弁２６が形成されている。図７では、貫通穴２５の全周にわたって弁２６が形成されている。図７の場合、弁２６の中央の穴２６ａの径がネジ２１の径より小さいが、弁２６が弾性力を有しているので、ネジ２１は弁２６の中央の穴２６ａを押し広げながら出入り可能である。
図６および図７は例であり、弁２６のサイズおよび数について特に規定は無い。ネジ２１のサイズなどに合わせて適切なサイズおよび数を設定すればよい。6 and 7 are plan views of the valve 26 as viewed from the direction of the arrow Y2 in FIG. In FIG. 6, three valves 26 are formed for one through hole 25. In FIG. 7, the valve 26 is formed over the entire circumference of the through hole 25. In the case of FIG. 7, the diameter of the central hole 26a of the valve 26 is smaller than the diameter of the screw 21. However, since the valve 26 has elasticity, the screw 21 enters and exits while expanding the central hole 26a of the valve 26. Is possible.
FIG. 6 and FIG. 7 are examples, and there is no particular limitation on the size and number of the valves 26. An appropriate size and number may be set according to the size of the screw 21 and the like.

図５（ａ）に示すように、ネジ２１を矢印Ｙ２の方向に締結する際、ネジ２１の先端部が弁２６を押し下げながら貫通穴２５に入り、ネジ２１のオネジ部２３が車両側ネジ穴２７のメネジ部２８に螺合する。弁２６が弾性力を有しているため、ネジ２１の挿入を妨げることは無い。図５（ｂ）に示すようにネジ２１が締結された状態では、弁２６が下向きになっている。ただし、最初から弁２６を下向きに形成してもよい。   As shown in FIG. 5A, when the screw 21 is fastened in the direction of the arrow Y2, the tip of the screw 21 enters the through hole 25 while pushing down the valve 26, and the male screw portion 23 of the screw 21 is the vehicle-side screw hole. 27 is screwed into the female screw portion 28. Since the valve 26 has an elastic force, the insertion of the screw 21 is not hindered. In the state where the screw 21 is fastened as shown in FIG. 5B, the valve 26 faces downward. However, the valve 26 may be formed downward from the beginning.

ネジ２１を緩める際、ネジ２１が回転すると、ネジ２１のオネジ部２３と車両側ネジ穴２７のメネジ部２８との螺合によってネジ２１が矢印Ｙ１の方向に移動し、ネジ２１が車両側ネジ穴２７から外れていく。このとき、被締結部２４の弁２６がネジ２１に弾性接触し、オネジ部２３を引っ掛ける。そのため、ネジ２１のオネジ部２３と車両側ネジ穴２７のメネジ部２８との螺合が外れても、弁２６がメネジの役割を果たし、ネジ２１が矢印Ｙ１の方向に移動していく。   When the screw 21 is rotated when the screw 21 is loosened, the screw 21 is moved in the direction of the arrow Y1 by the screwing of the male screw portion 23 of the screw 21 and the female screw portion 28 of the vehicle-side screw hole 27, and the screw 21 is moved to the vehicle-side screw. Remove from hole 27. At this time, the valve 26 of the fastened portion 24 comes into elastic contact with the screw 21 and hooks the male screw portion 23. Therefore, even if the male screw portion 23 of the screw 21 and the female screw portion 28 of the vehicle-side screw hole 27 are disengaged, the valve 26 functions as a female screw, and the screw 21 moves in the direction of the arrow Y1.

最後に、図５（ｃ）に示すようにネジ２１が車両側ネジ穴２７から完全に外れた状態になる。この状態では、ネジ２１のオネジ部２３が被締結部２４の弁２６に保持されているので、ディスプレイ１００を矢印Ｘ２の方向（図２）にスライドさせて意匠パネル２００から取り外し可能である。   Finally, as shown in FIG. 5C, the screw 21 is completely removed from the vehicle-side screw hole 27. In this state, since the male screw portion 23 of the screw 21 is held by the valve 26 of the fastened portion 24, the display 100 can be detached from the design panel 200 by sliding in the direction of the arrow X2 (FIG. 2).

なお、オネジ部２３の先端部が先細り形状であっても、その先端部に弁２６が弾性接触するので、ネジ２１を保持可能である。
また、ネジ２１にタッピングネジを使用する場合は、メネジ部２８の事前のネジ切りは不要である。Even if the distal end portion of the male screw portion 23 is tapered, the valve 21 is elastically contacted with the distal end portion, so that the screw 21 can be held.
In addition, when a tapping screw is used as the screw 21, it is not necessary to cut the female thread portion 28 in advance.

以上より、実施の形態２に係るネジ構造２０において、被締結部２４は、貫通穴２５の周縁部から内側に突出してネジ２１に弾性接触し、ディスプレイ１００を取り外す場合にネジ２１を車両側ネジ穴２７から外れた状態で保持する弁２６を有する構成にした。これにより、被締結部２４がスライドするときにネジ２１が車両側ネジ穴２７に干渉しないので、ネジ２１を緩めるだけでディスプレイ１００を意匠パネル２００から取り外し可能な状態にすることができる。   As described above, in the screw structure 20 according to the second embodiment, the fastened portion 24 protrudes inward from the peripheral portion of the through hole 25 to elastically contact the screw 21, and the screw 21 is screwed to the vehicle side screw when removing the display 100. The valve 26 is configured to be held in a state of being removed from the hole 27. Thereby, since the screw 21 does not interfere with the vehicle-side screw hole 27 when the fastened portion 24 slides, the display 100 can be removed from the design panel 200 only by loosening the screw 21.

実施の形態３．
図８は、実施の形態３に係るネジ構造３０の構成を示す断面図であり、図８（ａ）はネジ３１を締結する前の状態、図８（ｂ）はネジ３１を締結した状態、図８（ｃ）はネジ３１を完全に緩めた状態である。
このネジ構造３０は、図２に示したネジ構造１０の代わりに、ディスプレイ１００の筐体１０１と意匠パネル２００とに形成されるものである。また、ディスプレイ１００と意匠パネル２００の基本的な構成は、図２および図１４〜図１８と同じである。Embodiment 3 FIG.
FIG. 8 is a cross-sectional view showing the configuration of the screw structure 30 according to the third embodiment. FIG. 8A is a state before the screw 31 is fastened, and FIG. 8B is a state where the screw 31 is fastened. FIG. 8C shows a state in which the screw 31 is completely loosened.
This screw structure 30 is formed on the housing 101 of the display 100 and the design panel 200 instead of the screw structure 10 shown in FIG. The basic configurations of the display 100 and the design panel 200 are the same as those in FIGS. 2 and 14 to 18.

実施の形態３に係るネジ構造３０では、ネジ３１に、頭部３２と、ネジ山の無い円筒部３３と、ネジ山の有るオネジ部３４とが形成されている。円筒部３３の径ｄ３３は、オネジ部３４の径ｄ３４よりも小さい径にする必要がある（ｄ３３＜ｄ３４）。また、円筒部３３の軸方向の長さｔ３３は、被締結部３５の厚みｔ３５よりも長くする必要がある（ｔ３３＞ｔ３５）。これらの理由については後述する。   In the screw structure 30 according to the third embodiment, the screw 31 is formed with a head portion 32, a cylindrical portion 33 without a screw thread, and a male screw portion 34 with a screw thread. The diameter d33 of the cylindrical portion 33 needs to be smaller than the diameter d34 of the male screw portion 34 (d33 <d34). Further, the axial length t33 of the cylindrical portion 33 needs to be longer than the thickness t35 of the fastened portion 35 (t33> t35). These reasons will be described later.

ディスプレイ１００の筐体１０１に形成された被締結部３５には、貫通穴３６が形成され、この貫通穴３６に数ピッチ分の第２メネジ部３７が形成されている。車両側の意匠パネル２００には、車両側ネジ穴３８が形成され、この車両側ネジ穴３８に第１メネジ部３９が形成されている。第２メネジ部３７および第１メネジ部３９は、ネジ３１のオネジ部３４に螺合する。   A through hole 36 is formed in the fastened portion 35 formed in the housing 101 of the display 100, and second female screw portions 37 corresponding to several pitches are formed in the through hole 36. A vehicle-side screw hole 38 is formed in the design panel 200 on the vehicle side, and a first female screw portion 39 is formed in the vehicle-side screw hole 38. The second female screw portion 37 and the first female screw portion 39 are screwed into the male screw portion 34 of the screw 31.

図８（ａ）に示すように、ネジ３１を矢印Ｙ２の方向に締結する際、ネジ３１のオネジ部３４は、先ず被締結部３５の第２メネジ部３７に螺合し、その次に車両側ネジ穴３８の第１メネジ部３９に螺合する。ネジ３１は、頭部３２が貫通穴３６の縁に引っ掛かるまで、矢印Ｙ２の方向に移動していく。   As shown in FIG. 8A, when the screw 31 is fastened in the direction of the arrow Y2, the male screw portion 34 of the screw 31 is first screwed into the second female screw portion 37 of the fastened portion 35, and then the vehicle. The first female screw portion 39 of the side screw hole 38 is screwed. The screw 31 moves in the direction of the arrow Y <b> 2 until the head 32 is hooked on the edge of the through hole 36.

図８（ｂ）に示すようにネジ３１が締結された状態では、車両側ネジ穴３８の第１メネジ部３９とネジ３１のオネジ部３４が使用される。被締結部３５は、車両側ネジ穴３８の第１メネジ部３９とネジ３１のオネジ部３４との螺合により、車両側に固定される。一方、ネジ３１の円筒部３３にはネジ山が無いため、被締結部３５の第２メネジ部３７は使用されない。   As shown in FIG. 8B, in the state where the screw 31 is fastened, the first female screw portion 39 of the vehicle side screw hole 38 and the male screw portion 34 of the screw 31 are used. The fastened portion 35 is fixed to the vehicle side by screwing the first female screw portion 39 of the vehicle-side screw hole 38 and the male screw portion 34 of the screw 31. On the other hand, since the cylindrical portion 33 of the screw 31 has no thread, the second female screw portion 37 of the fastened portion 35 is not used.

ここで、図９を参照して、ネジ山の無い円筒部３３を設けたことによる効果を説明する。
図９に参考例として示したネジ２１は、頭部２２の直下からネジ山が形成されている。
つまり、頭部２２の直下からオネジ部２３が形成されている。被締結部３５と意匠パネル２００との間に隙間が存在している状態でネジ２１を貫通穴３６の第２メネジ部３７に締結していくと、頭部２２が貫通穴３６の縁に引っ掛かるまではネジ２１が回転するが、それ以上は、オネジ部２３と第２メネジ部３７とが螺合するので、回転できない。従って、被締結部３５と意匠パネル２００との間に隙間が残り、ディスプレイ１００ががたついてしまう。Here, with reference to FIG. 9, the effect by providing the cylindrical part 33 without a screw thread is demonstrated.
The screw 21 shown as a reference example in FIG. 9 has a screw thread formed immediately below the head 22.
That is, the male screw portion 23 is formed from directly below the head portion 22. When the screw 21 is fastened to the second female screw part 37 of the through hole 36 in a state where a gap exists between the fastened part 35 and the design panel 200, the head 22 is caught on the edge of the through hole 36. Until then, the screw 21 rotates. However, since the male screw portion 23 and the second female screw portion 37 are screwed together, the screw 21 cannot be rotated. Therefore, a gap remains between the fastened portion 35 and the design panel 200, and the display 100 is rattled.

これに対して、図８のようにネジ３１に円筒部３３を形成することにより、円筒部３３は貫通穴３６の第２メネジ部３７に螺合しないので、被締結部３５が意匠パネル２００に当接するまでネジ３１が回転できる。従って、被締結部３５と意匠パネル２００との間に隙間が残らない。
この効果を奏するために、円筒部３３の径ｄ３３を、オネジ部３４の径ｄ３４よりも小さい径にし、円筒部３３の軸方向の長さｔ３３を、被締結部３５の厚みｔ３５よりも長くしてある。In contrast, by forming the cylindrical portion 33 on the screw 31 as shown in FIG. 8, the cylindrical portion 33 is not screwed into the second female screw portion 37 of the through hole 36, so that the fastened portion 35 is attached to the design panel 200. The screw 31 can rotate until it abuts. Therefore, no gap remains between the fastened portion 35 and the design panel 200.
In order to achieve this effect, the diameter d33 of the cylindrical portion 33 is made smaller than the diameter d34 of the male screw portion 34, and the axial length t33 of the cylindrical portion 33 is made longer than the thickness t35 of the fastened portion 35. It is.

ネジ３１を緩める際、ネジ３１が回転すると、図８（ｃ）に示すようにネジ３１のオネジ部３４と車両側ネジ穴３８の第１メネジ部３９との螺合、およびネジ３１のオネジ部３４と貫通穴３６の第２メネジ部３７との螺合によってネジ３１が矢印Ｙ１の方向に移動し、ネジ３１が車両側ネジ穴３８および貫通穴３６から外れていく。ネジ３１のオネジ部３４は、車両側ネジ穴３８の第１メネジ部３９との螺合が外れても、被締結部３５の第２メネジ部３７とは螺合しているので、ネジ３１が矢印Ｙ１の方向に移動していく。   When the screw 31 is loosened when the screw 31 is loosened, as shown in FIG. 8C, the male screw portion 34 of the screw 31 and the first female screw portion 39 of the vehicle side screw hole 38 are screwed together, and the male screw portion of the screw 31. The screw 31 is moved in the direction of the arrow Y1 by screwing the screw 34 and the second female screw portion 37 of the through hole 36, and the screw 31 is detached from the vehicle side screw hole 38 and the through hole 36. The male screw portion 34 of the screw 31 is screwed with the second female screw portion 37 of the fastened portion 35 even if the screwing with the first female screw portion 39 of the vehicle-side screw hole 38 is disengaged. It moves in the direction of arrow Y1.

最後に、図８（ｃ）に示すようにネジ３１が車両側ネジ穴３８から完全に外れた状態になる。この状態では、ネジ３１のオネジ部３４が被締結部３５の第２メネジ部３７と螺合しているので、ディスプレイ１００を矢印Ｘ２の方向（図２）にスライドさせて意匠パネル２００から取り外し可能である。   Finally, as shown in FIG. 8C, the screw 31 is completely removed from the vehicle-side screw hole 38. In this state, since the male thread portion 34 of the screw 31 is screwed with the second female thread portion 37 of the fastened portion 35, the display 100 can be detached from the design panel 200 by sliding in the direction of the arrow X2 (FIG. 2). It is.

なお、ネジ３１にタッピングネジを使用する場合は、第２メネジ部３７と第１メネジ部３９の事前のネジ切りは不要である。
また、図１０に示すように、ネジ３１の先端部３４ａが先細り形状になっている場合、その先端部３４ａが意匠パネル２００の車両側ネジ穴３８から完全に外れた状態で、オネジ部３４と被締結部３５の第２メネジ部３７とが螺合するように、被締結部３５を厚くする。In addition, when using a tapping screw for the screw 31, the prior thread cutting of the 2nd female thread part 37 and the 1st female thread part 39 is unnecessary.
As shown in FIG. 10, when the tip portion 34 a of the screw 31 is tapered, the screw portion 34 and the screw portion 34 are in a state where the tip portion 34 a is completely removed from the vehicle-side screw hole 38 of the design panel 200. The to-be-fastened part 35 is made thick so that the 2nd female thread part 37 of the to-be-fastened part 35 may be screwed together.

以上より、実施の形態３に係るネジ構造３０において、ネジ３１は、頭部３２とオネジ部３４との間に形成され被締結部３５の厚みよりも長い円筒部３３を有し、車両側ネジ穴３８は、ネジ３１のオネジ部３４と螺合してディスプレイ１００を意匠パネル２００に固定する第１メネジ部３９を有し、被締結部３５の貫通穴３６は、ディスプレイ１００を取り外す場合にネジ３１のオネジ部３４と螺合してネジ３１を車両側ネジ穴３８から外れた状態で保持し、ネジ３１の円筒部３３を挿通させる第２メネジ部３７を有する構成にした。
これにより、被締結部３５がスライドするときにネジ３１が車両側ネジ穴３８に干渉しないので、ネジ３１を緩めるだけでディスプレイ１００を意匠パネル２００から取り外し可能な状態にすることができる。As described above, in the screw structure 30 according to the third embodiment, the screw 31 has the cylindrical portion 33 that is formed between the head portion 32 and the male screw portion 34 and is longer than the thickness of the fastened portion 35, and is a vehicle-side screw. The hole 38 has a first female screw portion 39 that is screwed into the male screw portion 34 of the screw 31 to fix the display 100 to the design panel 200, and the through hole 36 of the fastened portion 35 is a screw when the display 100 is removed. The screw 31 is screwed with the male screw 34 to hold the screw 31 in a state where it is removed from the vehicle-side screw hole 38, and the second female screw 37 for inserting the cylindrical portion 33 of the screw 31 is provided.
Thereby, since the screw 31 does not interfere with the vehicle side screw hole 38 when the fastened part 35 slides, the display 100 can be removed from the design panel 200 only by loosening the screw 31.

実施の形態４．
図１１は、実施の形態４に係るネジ構造４０の構成を示す断面図であり、図１１（ａ）はネジ４１を締結した状態、図１１（ｂ）はネジ４１を緩めた状態、図１１（ｃ）と図１１（ｄ）は被締結部４４がスライドしている途中の状態である。また、図１１（ａ）のネジ構造４０の斜視図を図１２（ａ）、平面図を図１２（ｂ）に示し、図１１（ｄ）のネジ構造４０の斜視図を図１３（ａ）、平面図を図１３（ｂ）に示す。このネジ構造４０は、図２に示したネジ構造１０の代わりに、ディスプレイ１００の筐体１０１と意匠パネル２００とに形成されるものである。また、ディスプレイ１００と意匠パネル２００の基本的な構成は、図２および図１４〜図１８と同じである。Embodiment 4 FIG.
11A and 11B are cross-sectional views showing the configuration of the screw structure 40 according to the fourth embodiment. FIG. 11A shows a state where the screw 41 is fastened, FIG. 11B shows a state where the screw 41 is loosened, and FIG. (C) and FIG.11 (d) are the states in the middle of the to-be-fastened part 44 sliding. 11A is a perspective view of the screw structure 40 of FIG. 11A, FIG. 12B is a plan view thereof, and FIG. 13A is a perspective view of the screw structure 40 of FIG. A plan view is shown in FIG. The screw structure 40 is formed on the housing 101 of the display 100 and the design panel 200 instead of the screw structure 10 shown in FIG. The basic configurations of the display 100 and the design panel 200 are the same as those in FIGS. 2 and 14 to 18.

実施の形態４に係るネジ構造４０では、ネジ４１は、頭部４２とオネジ部４３とを有する一般的な形状である。オネジ部４３は、車両側の意匠パネル２００に形成された車両側ネジ穴４８のメネジ部４９に螺合する。   In the screw structure 40 according to the fourth embodiment, the screw 41 has a general shape having a head portion 42 and a male screw portion 43. The male screw portion 43 is screwed into a female screw portion 49 of a vehicle-side screw hole 48 formed in the vehicle-side design panel 200.

ディスプレイ１００の筐体１０１に形成された被締結部４４には、ネジ４１のオネジ部４３を貫通させる貫通穴４５と、貫通穴４５から一方向に延びた長穴４６と、長穴４６の周縁を囲うスロープ部４７とが形成されている。図１２および図１３に示すように、貫通穴４５の周縁部がネジ４１の座面になり、頭部４２とオネジ部４３とで構成される段部を引っ掛ける。この貫通穴４５には、ディスプレイ１００のスライド方向に延びる長穴４６が連結されている。また、長穴４６の周縁部には、スロープ部４７として、上面が傾斜した壁が設けられている。スロープ部４７の上面の傾斜面は、貫通穴４５側が最も低く、ディスプレイ１００を意匠パネル２００から取り外すときにスライドさせる矢印Ｘ２の方向に向かうにつれて高くなる。   The fastened portion 44 formed in the housing 101 of the display 100 includes a through hole 45 that penetrates the male screw portion 43 of the screw 41, a long hole 46 that extends in one direction from the through hole 45, and a peripheral edge of the long hole 46. And a slope portion 47 is formed. As shown in FIGS. 12 and 13, the peripheral portion of the through hole 45 becomes a seating surface of the screw 41, and a step portion constituted by a head portion 42 and a male screw portion 43 is hooked. An elongated hole 46 extending in the sliding direction of the display 100 is connected to the through hole 45. Further, a wall having an inclined upper surface is provided as a slope portion 47 on the peripheral edge of the long hole 46. The slope of the upper surface of the slope portion 47 is the lowest on the through hole 45 side and becomes higher in the direction of the arrow X2 that is slid when the display 100 is removed from the design panel 200.

図１１（ａ）および図１２に示すようにネジ４１が締結された状態では、ネジ４１のオネジ部４３が車両側ネジ穴４８のメネジ部４９に螺合している。また、ディスプレイ１００を矢印Ｘ２の方向にスライドさせて意匠パネル２００から無理に引き出そうとしても、貫通穴４５と長穴４６との切り替わり部分に立設されたスロープ部４７の壁部４７ａが、ネジ４１の頭部４２に当接するため、引き出すことができない。   In the state where the screw 41 is fastened as shown in FIGS. 11A and 12, the male screw portion 43 of the screw 41 is screwed into the female screw portion 49 of the vehicle-side screw hole 48. Further, even if the display 100 is slid in the direction of the arrow X2 and forcibly pulled out from the design panel 200, the wall portion 47a of the slope portion 47 erected at the switching portion between the through hole 45 and the long hole 46 is screwed. Since it abuts on the head 42 of 41, it cannot be pulled out.

ネジ４１を緩める際、ネジ４１が回転すると、ネジ４１のオネジ部４３と車両側ネジ穴４８のメネジ部４９との螺合によってネジ４１が矢印Ｙ１の方向に移動し、ネジ４１がメネジ部４９から外れていく。図１１（ｂ）に示すように、完全にネジ４１を緩めた場合でも、オネジ部４３の先端の不完全ネジ部４３ａが車両側ネジ穴４８内に残った状態になる。
もし、この状態でネジ４１を矢印Ｙ１の方向に引き抜けば、簡単に車両側ネジ穴４８から抜けるような状態である。When the screw 41 is rotated when the screw 41 is loosened, the screw 41 is moved in the direction of the arrow Y1 by the screwing of the male screw portion 43 of the screw 41 and the female screw portion 49 of the vehicle side screw hole 48, and the screw 41 is moved to the female screw portion 49. Get out of it. As shown in FIG. 11B, even when the screw 41 is completely loosened, the incomplete screw portion 43 a at the tip of the male screw portion 43 remains in the vehicle-side screw hole 48.
If the screw 41 is pulled out in the direction of the arrow Y1 in this state, it can be easily pulled out from the vehicle-side screw hole 48.

図１１（ｂ）の状態のとき、被締結部４４が矢印Ｘ２の方向にスライドすると、ネジ４１の頭部４２の首下に被締結部４４のスロープ部４７が潜り込み、図１１（ｃ）の状態になる。図１１（ｃ）で示される状態からさらに被締結部４４が矢印Ｘ２の方向にスライドすると、スロープ部４７がネジ４１の頭部４２を引っ掛けた状態で傾斜に沿ってネジ４１を押し上げていくので、図１１（ｄ）および図１３に示すようにネジ４１が車両側ネジ穴４８から完全に外れた状態になる。このとき、ネジ４１の不完全ネジ部４３ａ側の先端は、スロープ部４７の内側に開口した長穴４６に逃げる。   In the state of FIG. 11B, when the fastened portion 44 slides in the direction of the arrow X2, the slope portion 47 of the fastened portion 44 sinks under the neck of the head portion 42 of the screw 41, and FIG. It becomes a state. When the fastened portion 44 further slides in the direction of the arrow X2 from the state shown in FIG. 11C, the slope portion 47 pushes up the screw 41 along the inclination with the head portion 42 of the screw 41 hooked. 11 (d) and FIG. 13, the screw 41 is completely removed from the vehicle-side screw hole 48. At this time, the tip of the screw 41 on the incomplete screw portion 43 a side escapes into the long hole 46 opened inside the slope portion 47.

なお、ネジ４１にタッピングネジを使用する場合は、メネジ部４９の事前のネジ切りは不要である。
また、ネジ４１の頭部４２に当接する壁部４７ａの位置、およびスロープ部４７の上面の傾斜角度等の詳細構造は、各部の形状等に応じて設定すればよい。例えば、壁部４７ａを頭部４２の縁ぎりぎりになる位置に配置すれば、ディスプレイ１００のスライド方向のがたつきが抑えられる。また例えば、スロープ部４７の上面の傾斜角度を急にすれば、短いスライド距離でネジ４１を車両側ネジ穴４８から引き抜くことができる。ただし、スロープ部４７の上面の傾斜角度が急すぎると、ネジ４１の頭部４２が引っ掛かって首下に潜り込むことが困難になる。In addition, when using a tapping screw for the screw 41, it is not necessary to cut the female thread portion 49 in advance.
Further, the detailed structure such as the position of the wall portion 47a contacting the head portion 42 of the screw 41 and the inclination angle of the upper surface of the slope portion 47 may be set according to the shape of each portion. For example, if the wall portion 47a is arranged at a position that is close to the edge of the head portion 42, shakiness in the sliding direction of the display 100 can be suppressed. Further, for example, if the inclination angle of the upper surface of the slope portion 47 is made steep, the screw 41 can be pulled out from the vehicle-side screw hole 48 with a short slide distance. However, if the inclination angle of the upper surface of the slope portion 47 is too steep, it becomes difficult for the head portion 42 of the screw 41 to be caught and go under the neck.

以上より、実施の形態４に係るネジ構造４０において、被締結部４４は、貫通穴４５側が低く当該被締結部４４のスライド方向に向かって高くなる傾斜面状であってディスプレイ１００を取り外す場合に緩んだネジ４１の頭部４２を引っ掛けスライドに伴って押し上げるスロープ部４７を有する構成にした。これにより、被締結部４４がスライドするときにネジ４１が車両側ネジ穴４８に干渉しないので、ネジ４１を緩めるだけでディスプレイ１００を意匠パネル２００から取り外し可能な状態にすることができる。   As described above, in the screw structure 40 according to the fourth embodiment, the fastened portion 44 has an inclined surface shape that is low on the through-hole 45 side and becomes high in the sliding direction of the fastened portion 44 and removes the display 100. The head portion 42 of the loose screw 41 is hooked and is configured to have a slope portion 47 that pushes up along with the slide. Thereby, since the screw 41 does not interfere with the vehicle-side screw hole 48 when the fastened portion 44 slides, the display 100 can be removed from the design panel 200 only by loosening the screw 41.

なお、上記実施の形態１〜４では、ディスプレイを意匠パネルに取り付ける場合を例にしてネジ構造を説明したが、ディスプレイに限定されるものではなく、車両に搭載する車載機器であれば何でもよい。
また、ネジ穴の軸方向（矢印Ｙ１の方向）と直交する方向（矢印Ｘ２の方向）にディスプレイをスライドする場合を例示したが、本発明において直交とは略直交の意味であり、矢印Ｙ１，Ｘ２のなす角度は上記効果を奏する範囲内であれば９０度近辺の角度であっても構わない。In the first to fourth embodiments, the screw structure has been described taking the case where the display is attached to the design panel as an example. However, the screw structure is not limited to the display and may be any in-vehicle device mounted on the vehicle.
Moreover, although the case where the display is slid in the direction (direction of arrow X2) orthogonal to the axial direction (direction of arrow Y1) of the screw hole is illustrated, in the present invention, orthogonal means substantially orthogonal, and arrows Y1, The angle formed by X2 may be an angle around 90 degrees as long as it is within the range where the above effect is achieved.

上記以外にも、本発明はその発明の範囲内において、各実施の形態の自由な組み合わせ、あるいは各実施の形態の任意の構成要素の変形、もしくは各実施の形態において任意の構成要素の省略が可能である。   In addition to the above, within the scope of the present invention, the present invention can be freely combined with each embodiment, modified any component of each embodiment, or omitted any component in each embodiment. Is possible.

以上のように、この発明に係るネジ構造は、ネジを緩めるだけで車載機器を車両から取り外し可能な状態にできるので、取り外すときのスライド方向とネジの締結方向とが略直交する構造の車載機器に用いるネジ構造に適している。   As described above, the screw structure according to the present invention can make the in-vehicle device detachable from the vehicle simply by loosening the screw, so the in-vehicle device has a structure in which the sliding direction and the fastening direction of the screw are substantially orthogonal to each other.
