【考案の詳細な説明】 本案は、自動車のカウルパネルの取付等に適当
な固定具に関する。[Detailed Description of the Invention] The present invention relates to a fixture suitable for attaching a cowl panel of an automobile.

例えば、通常の自動車輌にあつては、フロント
グラスとボンネツトとの間のボデー部分に、通気
孔を担うパネルとしての所謂カウルパネルを装着
する必要がある。然し、従来は、このカウルパネ
ルの対応ボデー部分への取付けを、通常の捩じ止
めによつて行つていたために、極めて作業性の悪
いものとなつていた。また、取付けるだけでな
く、修理点検時等、取外しを行う時にも面倒で、
特に裏側に手を入れてビス乃至ナツトを抑えてか
ら他側でナツト乃至ビスを捻回せねばならず、面
倒なだけでなく、手を傷付けたりする虞れもあつ
たし、また、取付部分での発錆の問題も残されて
いた。 For example, in a typical automobile, it is necessary to mount a so-called cowl panel, which serves as a panel serving as a ventilation hole, in the body portion between the windshield and the bonnet. However, in the past, the cowl panel was attached to the corresponding body part using ordinary screws, which resulted in extremely poor workability. In addition, it is troublesome not only to install it, but also to remove it for repairs and inspections.
In particular, it was necessary to put your hands on the back side and hold down the screws or nuts before twisting the nuts or screws on the other side, which was not only troublesome, but also risked hurting your hands. The problem of rusting also remained.

これに対して、従来からも、一応は片側操作で
済む固定具が特開昭50−66650号公報中の第３〜
５図に従来例として示してある。 On the other hand, conventional fixing devices that can be operated on one side have been proposed in Japanese Patent Application Laid-open No. 50-66650.
FIG. 5 shows a conventional example.

簡単に説明すると、中空の栓体と、この栓体の
中空部に捩込まれる中栓とから成つていて、中栓
の先端のネジ部を、中空栓体の下端部内面にある
雌ネジに捩じ込んでいくことによつて該下端部を
拡開し、この拡開した下端部と上部の頭部との間
に被締結物を挾むようにして該被締結物に固着す
るものである。 Briefly, it consists of a hollow stopper and a middle stopper that is screwed into the hollow part of the stopper. By screwing in, the lower end portion is expanded, and the object to be fastened is sandwiched between the expanded lower end portion and the upper head, and the object to be fastened is fixed to the object.

しかし、この固定具は、中空栓体に中栓を装
着する作業、即ち固定作業は何回とないネジの捻

全にネジ係合させることを予定しているため、取
付孔の径許容性が極めて乏しい；即ち、中空栓体
の下端部内面の雌ネジが中栓の乃ジと丁度係合し
た時の該下端部の拡開度は一定であるため、小径
の孔に対しては下端部が拡開し切れずに、無理に
捩じ込まれてくるネジ山を損傷したり、大径孔で
あると、拡開が足りずに、ぐら付きを生んだりし
てしまう、径許容範囲（極めて狭いことは上
述）内での径変動は、孔内縁が下端部を締付ける
力の変動を直接に生み、ネジ締結力が変動するた
め、固定力を一定に維持することが難しく、必要
に応じての中栓の捻回取外作業時の捻回トルク、
従つて作業力も大きく変わつてしまう、等々の欠
点がある。 However, with this fixing tool, the work of attaching the inner plug to the hollow plug body, that is, the fixing work, involves twisting the screw several times, which is extremely inefficient and does not allow complete screw engagement. Because of the planned design, the diameter tolerance of the mounting hole is extremely poor; in other words, when the female screw on the inner surface of the lower end of the hollow plug just engages with the hole of the inner plug, the degree of expansion of the lower end is constant. Therefore, for small diameter holes, the lower end may not fully expand and damage the screw threads that are forced into it, and for large diameter holes, the lower end may not expand sufficiently. Diameter fluctuations within the diameter tolerance range (extremely narrow as mentioned above), which can cause wobbling, directly cause fluctuations in the force with which the inner edge of the hole tightens the lower end, and the screw tightening force fluctuates. It is difficult to maintain a constant force, so it is necessary to adjust the twisting torque when removing the inner stopper.
Therefore, there are drawbacks such as the fact that the working power changes greatly.

さらに別な従来の固定具としては、実公昭49−
34919号公報に開示されたものがある。 Another conventional fixing device is
There is one disclosed in Publication No. 34919.

この固定具は、ネジ山を持つ金属製のピン（雄
部材）を合成樹脂製の雌部材の中に強引に押し込
むか捻り込むことにより、雌部材の脚を拡開させ
ると同時に、雄部材挿入孔の壁面に強引に雄部材
のネジ山を食い込ませて引き抜け防止力を得るも
のである。 This fixing device is made by forcibly pushing or twisting a threaded metal pin (male member) into the synthetic resin female member to spread the legs of the female member and simultaneously insert the male member. The screw thread of the male member is forcibly dug into the wall of the hole to obtain a pull-out prevention force.

しかし、こうした固定具では、雄部材のネジ山
により雌部材の対応する受容孔の壁面に強引な塑
性変形でネジを立てることから、当然、極めて大
きな挿入作業力を要し、作業性は悪化するし、ま
た、一旦取外したなら、再使用は原則としてまず
不可能となる。いつも必ず雌部材の同じ所にネジ
山が切られるとは限らないからである。 However, with these fixing devices, the threads of the male member force the screw into the wall of the corresponding receiving hole of the female member through forced plastic deformation, which naturally requires an extremely large insertion force, which deteriorates workability. However, once removed, reuse is basically impossible. This is because the threads are not always cut in the same place on the female member.

本案は以上に鑑てなされたもので、カウルパネ
ルのボデーへの着脱時の際に、片側操作を可能に
し、作業性を高めると共に、上記従来例固定具の
欠点をも解決する固定具を提供することを主目的
としたものである。勿論、この固定具は他の固定
用途にも応用できるものである。 The present invention has been developed in view of the above, and provides a fixing device that enables one-sided operation when attaching and detaching the cowl panel to the body, improving work efficiency, and also solving the drawbacks of the conventional fixing devices mentioned above. The main purpose is to Of course, this fixture can also be applied to other fixing applications.

以下、図示する実施例に就き詳起するが、留付

うに図つている。 The illustrated embodiment will be described in detail below, and the articles to be fastened are, for example, a body 1 and a cowl panel 2.
Then, as shown in FIGS. 1 and 2, through holes 3 and 3a that match the respective corresponding attachment parts are bored, and the fixing device 4 of the present invention is inserted into the series of through holes and fixed. It's on.

孔に整合する開口が開けられている。 Here, the cowl panel 2 is fixed to the body 1 by its end edge 5, which is provided one step downward from the surface portion 6 of the cowl panel, and on both sides there are rising walls 7, 7a is arranged. In this case, a sealing member 8 made of synthetic resin or rubber is fixed to the upper free end of the wall 7a on the tip side by biting into the groove 8a.
It is pre-assembled into a unit for the cowl panel.
The sealing material descends along the wall 7a that is engaged, is bent along the back surface of the edge 5, and reaches a portion 8b that is held between it and the body 1. This sealing member 8 also has an opening formed in its portion 8b that matches the through hole formed in the cowl panel edge and the body.

８を必要としない場合もある。 The free end of the seal member 8 on the side of the cowl panel surface 6 is a free edge 8c that is parallel to the surface or slightly upward as it moves away from the surface. This is to seal the space between them when the However, depending on the model, the seal member 8 may not be particularly necessary.

然して、カウルパネルをボデーに取付けるため
の固定具４は、その構成として第３図に示すもの
が挙げられる。 The structure of the fixture 4 for attaching the cowl panel to the body is shown in FIG. 3.

この固定具４は、雄部材９と、雌部材１０とか

いようにとのことから、この雄部材９もプラスチ
ツク製であることが望ましい。 This fixture 4 consists of a male member 9 and a female member 10, at least the female member being made of plastic. The male member 9 has a normal bolt shape,
It consists of a head 11 and a shaft 12 depending from the head, and in this case the shaft 12 is threaded over almost its entire length. It is preferable that the male member 9 is also made of plastic for molding purposes and to prevent unexpected damage to the female member in the engagement relationship described below.

雌部材１０は、カウルパネル及びボデーの一連

らず、少くとも対向して一対あれば良い。 The female member 10 is fitted into a series of through holes in the cowl panel and the body (which also includes the through holes in the seal member in this embodiment), and has a body portion 14 that protrudes through the tip thereof, and a body portion 14 for attaching the cowl panel. The trunk 14, which has a part, in this case a head 15 resting on the edge 5, and which morphologically hangs down from the head, is incised from the tip at a 90° angle in this case and has a base at the head. has four fixed elements 16... Thus, if the outer periphery of the body element is continuously traced, it is approximately circular, and the through holes in the cowl panel and the body (including the through holes in the seal member 8) are also circular. However, the number of body elements is not limited, as long as the base is fixed to the head and each has a free end at the tip, or if it has a certain length and can be expanded in diameter. It would be good if there was a pair facing each other.

合し得る雌ネジ１９が切られている。 From the upper surface of the head 15 to the middle of the length of the body element 16..., a receiving hole 17 is bored with a diameter that allows the male member shaft 12 to be comfortably accommodated. Even if it is a series, there remains only a space 18 whose diameter is much smaller than the diameter of the shaft. Conversely, a small diameter space portion 18 is formed by the inwardly bulging portion 18'. The bulging portion 1 of each trunk element 16 facing this small diameter space portion 18
A female thread 19 is cut on the inner surface of the shaft 8' and can be engaged with a thread provided on the shaft rod 12.

間に収まるようになつている。 Further, in this embodiment, wings 20, 20 are provided that extend diagonally downward from both sides of one opposing edge of the head, and the width thereof is equal to the walls 7, 7a on both sides of the cowl panel edge.
It seems to fit in between.

この固定具４を用いてのカウルパネル取付けは
次のようにして行う。 The cowl panel is attached using the fixture 4 as follows.

先づ、第４図示のように、この場合シール部材

掛かることもなく、スムースに挿入作業が行え
る。 First, as shown in FIG. 4, after aligning the through holes 3 and 3a with the body 1 by sandwiching the sealing member 8 and positioning the edge 5 as the corresponding attachment part of the cowl panel, the male member is attached. The female member 10, to which the male member has been temporarily fixed by placing the shaft rod 12 of No. 9 in the receiving hole 17, is passed through the series of through holes from the tip of the body 14, and the female member head 15 and this In this case, the tips of both wings, which are slightly lower than that, are brought into contact with the edge 5. In addition, even if the positions of the through holes are slightly shifted during the installation work into the initial through holes 3 and 3a, the outer surface of the tip of the body element, which will be the insertion end of the female member, will remain as shown in the figure. Since it has a tapered surface 22, this tapered surface acts as a guide surface, and the insertion operation can be performed smoothly without getting caught on the hole edge.

この状態から、雄部材９をその頭１１に力を加

の先端近傍内面間乃至膨出部１８′，１８′間の小
径空間部分１８内に強引に押し入つて行くことに
なり、もつて各胴部要素１６はボデー裏面に突出
した部分が外方に膨らむようになる。 From this state, force is applied to the head 11 of the male member 9 to push it further into the female member. Then, the tip of the shaft 12 is connected to each trunk element 16.
The body elements 16 are forcibly pushed into the small diameter space 18 between the inner surface near the tip or between the bulges 18' and 18'. It starts to swell.

一方、雌部材頭部１５は、雄部材頭部１１によ

翼部２０，２０もカウルパネル表面に沿うように
延展させられる。 On the other hand, the female member head 15 is forcibly pressed by the male member head 11, and the surface of the cowl panel (edge 5
The wing portions 20, 20 disposed on both sides are also extended along the surface of the cowl panel.

同時に、軸桿１２のネジ山１３は、押し拡げた
胴部要素先端内面の雌ネジ１９の一番上のネジ山
１９ａに係合し、もつて充二分な摩擦が生起して
雄部材９の戻りは抑止される。 At the same time, the thread 13 of the shaft 12 engages with the top thread 19a of the female thread 19 on the inner surface of the distal end of the body element which has been pushed out, and sufficient friction is generated to tighten the male member 9. Returns are suppressed.

従つて、一連の透孔３，３ａにおいて、ボデー

に堅固に固定されることになる。 Therefore, in the series of through holes 3, 3a, the outer circumferential edge 16' of each barrel element with a regular diameter is formed on the back side of the body.
Also, on the cowl panel side, the head 15 of the female member 10 is in forcible contact with each other, and since this state cannot be released due to the relationship between both screws 13 and 19, the cowl panel and the sealing means are in contact with each other. , will be firmly fixed to the body.

上記において、第４図に示されるように、本考
案の固定具によると、雄部材と雌部材とを完全に
ネジ係合させる前に、必要に応じあらかじめ雄部
材と雌部材とを仮止めないし仮組みできるという
こと、換言すれば雄部材の軸桿１２をその長さの
途中まで、雌部材の受容孔１７内に仮に挿入して
置けるということは、実際上、極めて好ましい。 In the above, as shown in FIG. 4, according to the fixing device of the present invention, the male member and the female member are not temporarily fastened in advance as necessary before the male member and the female member are completely screwed together. It is extremely desirable in practice to be able to temporarily assemble the male member, in other words to be able to temporarily insert the shaft 12 of the male member into the receiving hole 17 of the female member halfway along its length.

この種固定具を複数用いて複数個所での固定を
なす場合に、一般には全部の固定個所にあらかじ
めこの種固定具を位置付ける工程と、そのように
位置付いている固定具において雄部材を雌部材に
係合させて固定を完了させて行く工程とを別工程
とし、それぞれ作業を分業化するのが作業上、流
れが良く、合理的である。 When fixing at multiple locations using multiple fixing devices of this type, there is generally a step of positioning this type of fixing device in advance at all the fixing locations, and a process in which the male member and the female member are In terms of work flow, it is reasonable to divide the work by separating the process of engaging the parts and completing the fixing into separate processes.

しかるに、先に述べた実公昭59−34919号公報
に開示のような従来固定具にあつては、雄部材を
雌部材に仮に止めた状態で各固定個所に一つづつ
固定具を位置付けて置くということができない。
雄部材は雌部材に対し、完全に係合させるとこで
しか、挿入することができない。 However, in the case of the conventional fixing device as disclosed in the above-mentioned Japanese Utility Model Publication No. 59-34919, one fixing device is positioned at each fixing point with the male member temporarily fixed to the female member. I can't say that.
The male member can only be inserted into the female member when fully engaged.

したがつて、こうした従来固定具を複数用いて
複数個所での固定機能を営ませる場合には、まず
一個所でこの固定具を用いて完全な固定を図つて

作業項目を一人で行なわねばならない。 Therefore, when using multiple conventional fixing devices to perform the fixing function at multiple locations, first use this fixing device to achieve complete fixation at one location, and then attach the female member to the next fixing location. Insert the male member, push in the male member to complete the fixation at that location, and then move on to the next fixation location. Work items such as the work and pushing the male member must be done by one person.

Threaded portion 1 of female member 10 that engages with threaded portion 13 of 2
9 is located below the receiving hole 17 even if it is located in the body element 16 (small diameter space portion 18
(inner wall surface of the bulge), the receiving hole 1
The male member shaft 12 can be temporarily accommodated up to the bottom of the hole 7 without much resistance, and therefore the desired working process as described above can be adopted.

きるのである。 Furthermore, the fact that the male member and the female member can be temporarily assembled in this way means that transportation in that state is also possible. In practice, with conventional fixtures, temporary assembly was not possible and the male and female parts had to be transported separately, resulting in mismatched numbers or complete loss of one half, but with the present invention, Fixtures can eliminate such fears if necessary.

随的な機能を生んでいるのである。 Note that the wing pieces 20, 20 are originally intended to perform a rotation prevention function, which will be described later, and to securely close the series of through holes 3, 3a to provide watertightness. , exhibits a restoring force due to the elasticity of the material, which is transferred to a force that pulls up the female member, and further becomes a force that presses the tip of the body against the shaft rod, making the screw fit more secure. It produces a function.

しも可能なものとなつているのである。 As described above, the cowl panel is installed.
In effect, this was done simply by pushing the male member in on one side, but since the screw-fitting relationship is used to create the frictional force that maintains this state, it is also possible to remove it. .

毎摘み上げれば、分解することができる。 That is, from the completed installation state shown in Figure 5, rotate the head 11 of the male member in the direction in which the male member shaft thread 13 and the female thread 19 at the tip of the female member body are unthreaded. For example, the male member 9 gradually floats up, and when the tip of the shaft eventually comes off the small diameter portion 18 at the tip of the body, each body element 16 of the female member 9, as shown in FIG.
Each restores its own elasticity, and can be disassembled by picking up the female member along with the male member.

入れられる溝２１（第２，３図）を穿つている。 After being disassembled in this manner, the fixture of the present invention may be reused when necessary. On the other hand, the conventional fixing device disclosed in the above-mentioned Japanese Utility Model Publication No. 49-34919 cannot be reused in principle. This is because the threads are cut into the inner wall surface of the female member by plastic deformation, so it is impossible to imagine that the threads will always be placed in the same place. Although it is not an essential feature of the fixing device of the present invention, in order to facilitate rotation of the male member, in this embodiment, a groove 21 (FIGS. 2 and 3) for receiving the tip of the driver is provided in the head 11 of the male member. is wearing.

而して、雄部材を回転させる時には、雌部材迄
一緒に回転してしまつては具合が悪いが、この実
施例では、そのための回り止め手段として、頭部
１５両側から張出させた翼片２０，２０を設けて

回転は阻止されるのである。 Therefore, when the male member is rotated, it would be inconvenient if the female member also rotated together, but in this embodiment, wing pieces protruding from both sides of the head 15 are used as means for preventing rotation. 20,20 are provided. That is, as shown in Figure 6, when the male member is twisted, even if the female member initially rotates together, after a slight rotation, the corners of the wing pieces 20, 20 are located on the sides of the female member. It hits the walls on both sides and is prevented from rotating further.

以上、この実施例の構成は顕らかであろうが、
尚、雄部材軸桿１２に設けるネジ山１３は、図示
のように軸桿全長に亘つていなくとも、雌部材の
胴部先端で挿入された時に雌ネジ１９のある部分
近傍にあれば足りること自明であろう。 The configuration of this embodiment may be obvious from the above, but
Note that the thread 13 provided on the male member shaft 12 does not have to extend over the entire length of the shaft as shown in the figure, but it is sufficient if it is located near the part where the female thread 19 is located when inserted at the tip of the body of the female member. That should be obvious.

尚、カウルパネルとボデーとの間にシール部材
を配することは、水密性に加え、そのシール部材

述の弾性翼２０，２０の作用と同様に固定力の強
化を生むということからも都合が良い。 Furthermore, by disposing a seal member between the cowl panel and the body, in addition to being watertight, due to the elasticity of the seal member, immediately after inserting the male member, the member is slightly compressed and engaged with the female member. This is also advantageous because when the pressing force is released after that, the restoring force of the sealing member is used to strengthen the fixing force in the same manner as the effect of the elastic wings 20, 20 described above.

以上、本案によれば、固定作業は、雄部材９の
押し込みで良く、これに優るものはない。 As described above, according to the present invention, the fixing work can be done by pushing the male member 9, and there is nothing better than this.

単なる押し込みによる場合、雄部材のネジ部の

虞れはない。 If it is simply pushed in, each thread of the threaded part of the male member will forcibly advance over each thread of the threaded part of the inner wall surface of the small diameter portion of the receiving hole into which the male member of the female member is inserted. This is possible due to the elasticity of the material, and there is no risk of the screw threads being damaged.

無難である。 In addition, when removing the cowl panel as necessary, it is possible to forcefully pull it out instead of twisting the male member as described above, but in practice it is difficult to remove the cowl panel by pulling a tool or the like. In some cases, a knob for hanging is required on the male member, which undeniably has the disadvantage of making it more complicated and larger. Also,
It is not necessary to remove it very often,
Also, when removing it, it is desirable to be careful not to damage the surrounding parts, so in that sense, it is safer to rely on twisting the male member, which allows for careful removal.

する仂きを持つている。 Furthermore, the body part 14 is cut from the tip to form a body element 16 having a plurality of free tips.
..., but the point is that it is fine as long as the body element is expandable, so by inserting a window in the body, the tip is joined, but the horizontal part of the window above it can be expanded. It may be possible to open it. That is, in accordance with the illustrated embodiment, the bulge 1 of the body 14
It is sufficient to consider a configuration in which the portions of each guide surface 22 extend further downward beyond 8' and connect to each other, and the cut is closed at the lower end of the connection to form a window. In this case, when viewed as a whole, the bulge 18' is located halfway along the length. Further, although the guide surface has a longer guide length, it has the ability to tolerate irregularities in the hole in exactly the same way as described above.

更に、雌部材の頭部は勿論図示の形状に限ら
