用回転可動型後写ミラーの取付装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for a rotatable rear view mirror for a vehicle, which is rotatably mounted on the front side of a vehicle body.

車体においては車両後方の視界を得るための後手ミラー
を車体前面側部に取り付けているが、該ミラーは−ムを
介して車体外方向に突出して取り付けられているため、
車体に強固に固定取付したものでは走行中障害物と接触
した場合、障害物或いはミラーを著しく破損させたり、
又取付位置の低いものでは自転者等の走行者の人体に接
触して大きな事故を引き起す危険性を有していた。In the car body, a rear mirror is attached to the front side of the car body to obtain visibility behind the car, but since the mirror is attached to protrude outward from the car body through a
If the vehicle is firmly fixed to the vehicle body and comes into contact with an obstacle while driving, it may cause significant damage to the obstacle or mirror.
In addition, if the mounting position is low, there is a risk of contact with the body of a cyclist or other rider, causing a serious accident.

このため、第１図に示すようにミラ一本体１１を固定し
たアーム１２の両端部を車体１３の前面側部に固定した
取付用ブラケット１４（又はサブアーム）に回転可能に
ボルト締結して取り付けたものがある。Therefore, as shown in FIG. 1, both ends of the arm 12 to which the mirror body 11 is fixed are rotatably bolted to the mounting bracket 14 (or sub-arm) fixed to the front side of the vehicle body 13. There is something.

に戻すことは困難であった。In this device, when the mirror body 11 or the arm 12 comes into contact with an obstacle, the arm 12 receives contact pressure and rotates around the bolt that serves as the pivot, absorbing the impact caused by the contact and removing the obstacle from the human body or the like. It reduces damage to the mirrors, and when driving on narrow roads, by rotating the arm 12 inward of the vehicle in advance, it prevents contact with obstacles, resulting in excellent safety. -808
(Refer to Publication No. 41, etc.) However, in the conventional rotatable rear mirror, the arm integrated with the mirror, which is attached to the regular rotation position set to obtain the optimum rearward visibility of the vehicle, temporarily moves when an obstacle is detected. If the product is rotated artificially due to contact with the product or to avoid such contact, the only way to reset the product to its normal position is to do so by eye, which requires a tedious and nerve-wracking process, and also ensures that the product is in the correct position. It was difficult to return it to its original position.

本考案はかかる従来の欠点に鑑み為されたもので、ミラ
ー付アームを回転動作後も容易かつ確実に正規の取付位
置にセットし直すことのできるように構成した車両用回
転可動型後手ミラーの取付装置を提供するものである。The present invention has been devised in view of these conventional drawbacks, and is a rotatable rear mirror for a vehicle, which is constructed so that the arm with the mirror can be easily and reliably reset to the normal mounting position even after rotation. A mounting device is provided.

以下に本考案を図面に示す実施例に基づいて詳細に説明
する。The present invention will be described in detail below based on embodiments shown in the drawings.

第２図Ａは本考案の１実施例を示す。FIG. 2A shows one embodiment of the present invention.

図において、フロントウィンド２を挾んで車体前面パネ
ル１側部の上方及び下方位置には夫々アーム取付用ブラ
ケット３が固定され、これらブラケット３のフランジ部
にミラ一本体４を中間部に固定取付したアーム５の両端
部がボルト諦めされるが、少なくとも一方のアーム５端
部例えば図示上端部はブラケット３との間に本考案を構
成する保合部材６を挾んでボルト諦めされる。In the figure, arm mounting brackets 3 are fixed to the upper and lower positions of the sides of the vehicle body front panel 1, sandwiching the front window 2, respectively, and the mirror main body 4 is fixedly attached to the flange part of these brackets 3 at the middle part. Although both ends of the arm 5 are bolted, at least one end of the arm 5, for example, the upper end shown in the figure, is bolted with a retaining member 6 constituting the present invention interposed between it and the bracket 3.

係合部材６は第２図Ｂに示すように金属製又は樹脂製の
長板の中間部にボルト挿通孔６ａを形成し、後端部を前
記ブラケット３の折曲部に係合すべく下方に折曲し、か
つ、前端部を上方に折曲し、その上端縁をアーム５の下
部円周面に係合する円弧形状の係合面６ｂに削設して形
成される。As shown in FIG. 2B, the engaging member 6 has a bolt insertion hole 6a formed in the middle part of a long plate made of metal or resin, and its rear end is bent downward to engage with the bent part of the bracket 3. It is formed by bending the front end upward, and cutting its upper edge into an arc-shaped engagement surface 6b that engages with the lower circumferential surface of the arm 5.

かかる構成とすれば、係合部材６は後端部とブラケット
３との保合により、ブラケット３に対しては回転不能に
固定されるが、前端係合面６ｂとアーム５との係合は、
アーム５にボルト７軸回り回転方向の所定値以上の外力
を加えれば係合部材６がボルト挿通孔部を支点として下
方向に弾性変形することにより簡単に外れて、アーム５
のボルト７回りの回転が許容される。With this configuration, the engagement member 6 is fixed unrotatably to the bracket 3 by engagement between the rear end and the bracket 3, but the engagement between the front end engagement surface 6b and the arm 5 is ,
If an external force of more than a predetermined value is applied to the arm 5 in the direction of rotation around the axis of the bolt 7, the engagement member 6 will be elastically deformed downward using the bolt insertion hole as a fulcrum, and the arm 5 will be easily detached.
Rotation around bolt 7 is allowed.

この場合アーム５をボルト７回りに回転させ得る外力の
大きさは、ボルト７の締結力と係合部材６を所定量弾性
変形させるに要する力との合計で決まるが、後者はアー
ム５と係合部材６とが金属対金属又は金属対樹脂である
ため接触摩擦係数が小さいこともあって前者に比べて充
分小さく設計することができるから従来同様の大きさの
外力でアーム５の回転を許容させることができる。In this case, the magnitude of the external force that can rotate the arm 5 around the bolt 7 is determined by the sum of the fastening force of the bolt 7 and the force required to elastically deform the engaging member 6 by a predetermined amount. Since the mating member 6 is metal-to-metal or metal-to-resin, the contact friction coefficient is small, and it can be designed to be sufficiently smaller than the former, allowing the arm 5 to rotate with an external force of the same magnitude as in the past. can be done.

そして、アーム５が外力を受けて回転し、係合部材６と
の係合が外れた後、アーム５を元の位置に戻す場合、例
えば第２図Ａで鎖線位置まで回転したアーム５を実線位
置まで戻す場合には、アーム５の中間部を把んで戻し方
向に回転操作すれば、アーム５の下部円周面が係合部材
６の前端を下方に弾性変形させて係合面６ｂと係合する
正規の位置にセットし直すことができる。When the arm 5 rotates under external force and returns to its original position after disengaging from the engagement member 6, for example, the arm 5 rotated to the chain line position in FIG. To return the arm 5 to its original position, grip the middle part of the arm 5 and rotate it in the return direction, so that the lower circumferential surface of the arm 5 elastically deforms the front end of the engagement member 6 downward and engages with the engagement surface 6b. It can be reset to the correct position.

即ち、従来の如くアーム５を目分量によって正規の位置
にセットし直す面倒かつ不確実な位置決め操作に比べ、
本考案装置ではアーム５を係合面６ｂに係合させるだけ
の簡単な操作で、かつ係合部材６の係合面６ｂは、係合
部材６のボルト９による取付部から所定の距離を有した
箇所に設けられているため取付誤差も小さく正確な位置
決めが行なえる。That is, compared to the conventional positioning operation, which is troublesome and uncertain in that the arm 5 is reset to the correct position by eye,
In the device of the present invention, the simple operation is to engage the arm 5 with the engagement surface 6b, and the engagement surface 6b of the engagement member 6 has a predetermined distance from the attachment part of the engagement member 6 by the bolt 9. Since it is installed at a location where the mounting position is correct, the installation error is small and accurate positioning can be performed.

第３図は前記同様ブラケットを介したアーム取付方式に

面に突起片１６ａを形成し、該突起片１６ａをブラケッ
ト３の前端縁に回転不能に係合させるようにしたもので
ある。FIG. 3 shows another embodiment of the engaging member in the arm mounting method via a bracket as described above, in which a protruding piece 16a is formed on the lower surface of the engaging member 16, and the protruding piece 16a is attached to the front edge of the bracket 3. It is designed to be engaged in a non-rotatable manner.

すればよい。In addition, in the installation type in which the arm 5 to which the mirror body is attached is bolted to the sub-arm 8 fixed to the vehicle body, for example, as shown in FIG. An engaging portion 26 that rotatably engages the
It is sufficient to use an engaging member 26 having a side edge formed with an engaging portion 26a that engages with the side edge of the sub-arm 8 in a non-rotatable manner.

又は、第５図に示す如く、係合部材３６の後端部を上方
に折曲してサブアーム８円周面と充分大きな係合接触面
積をもってボルト軸回り回転不能に係合する係合部３６
ａを形成したものを使用してもよい。Alternatively, as shown in FIG. 5, an engaging portion 36 is formed by bending the rear end of the engaging member 36 upward to engage the circumferential surface of the sub-arm 8 with a sufficiently large engagement contact area so as not to rotate around the bolt axis.
You may use the one in which a is formed.

また、第６図に示す如く係合部材４６にバネ鋼の様な硬
度の高い材料を使用する場合には、係合部材によりパイ
プ塗装面に傷が発生する可能性がある。Further, as shown in FIG. 6, when a highly hard material such as spring steel is used for the engagement member 46, there is a possibility that the engagement member may cause scratches on the painted surface of the pipe.

その場合には、係合部４６ｂの如くの形状にしパイプと
の接触部の面積を拡大することにより面圧を下げたり、

装面の傷の発生を防止することが可能である。In that case, the surface pressure can be lowered by making the shape like the engaging part 46b and expanding the area of the contact part with the pipe.
By applying a resin coating to the engaging portion 46a, it is possible to prevent the occurrence of scratches on the painted surface of the pipe.

安全性向上にもつながるものである。As explained above, the present invention engages the arm to which the rear mirror is fixed at the normal mounting position of the arm, and the engagement is easily released by an external force in the rotational direction applied to the arm, causing the arm to rotate. Since the engaging part that allows the arm of the engaging member is provided at a predetermined distance from the attachment part that is given up together with the arm, it maintains the same safety function as the conventional one by rotating the arm, and also prevents the normal attachment by rotating. A simple return operation of engaging the arm that has come out of position with the engaging portion allows it to be accurately reset to the proper mounting position, which in turn leads to improved safety.
