【考案の詳細な説明】
本考案はバンパーの弾性支持構造の改良に関す
るものである。[Detailed Description of the Invention] The present invention relates to an improvement in the elastic support structure of a bumper.
従来、自動車用バンパーは、ボデーフレームに
ステーを介して固定した補強材に強固に取り付け
られた構造になつている。 Conventionally, an automobile bumper has a structure in which it is firmly attached to a reinforcing member fixed to a body frame via a stay.
しかしながら、従来の取付構造では、取付部が
強固に固定されているので、自動車のボデーに発
生する振動モードがバンパーの重量等により増大
する等の難点がある。 However, in the conventional mounting structure, since the mounting portion is firmly fixed, there is a problem that the vibration mode generated in the body of the automobile increases due to the weight of the bumper and the like.
そこで、本出願人は先にリジツト構造のバンパ
ーをボデーフレームに弾性体を介して支持する構
成のものを出願した。 Therefore, the present applicant previously applied for a structure in which a rigid bumper is supported on a body frame via an elastic body.
しかしながら、上記弾性体の亀裂あるいは弾性
体を加硫接着した板金部材のさび等により剥離し
てバンパーがボデーフレームから脱落するという
惧れがあつた。 However, there was a fear that the bumper would come off from the body frame due to cracks in the elastic body or rust in the sheet metal member to which the elastic body was vulcanized and bonded.
本考案は弾性体の亀裂あるいは弾性体を加硫接
着した板金部材のさび等により剥離してもバンパ
ーがボデーフレームに係合され脱落することを防
止したものである。 The present invention prevents the bumper from engaging with the body frame and falling off even if the elastic body peels off due to cracks or rust in the sheet metal member to which the elastic body is vulcanized and bonded.

うに形成されている。なお、ストツプ部材１３は
ボルト１５とナツト１６とを逆に取付けてパイプ
１２とナツト１６との間に取付けてもよい。 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. 1 is a body frame of an automobile, 2 is a reinforcing member to which a bumper is fixed, and 3 is a stay main body for attaching the reinforcing member 2 to the body frame 1. The reinforcing member 2 is attached by bolts 4 and nuts 5. 6 is a bracket attached to the stay body 3 with bolts 7 and nuts 8;
0 is formed. Reference numeral 11 denotes a cylindrical elastic body made of rubber or the like, whose outer side is vulcanized and bonded to the inner circumferential surface of the cylindrical portion 10 and whose inner side is vulcanized and bonded to the outer circumferential surface of the pipe 12. Reference numeral 13 denotes a stopper member interposed between the pipe 12 and the bolt 15 via the washer 14, and the bolt 15 and nut 16 stop the pipe 12.
It is fixed when attached to the body frame 1, and is formed to have a larger outer diameter than the inner diameter of the cylindrical portion 10. In addition, the stop member 13 may be attached between the pipe 12 and the nut 16 by attaching the bolt 15 and nut 16 in reverse.
従つて、上記実施例では弾性体１１の亀裂ある
いは弾性体１１を加硫接着したブラケツト６ある
いはパイプ１２のさび等により弾性体１１がブラ
ケツト６あるいはパイプ１２から剥離しても、ブ
ラケツト６の筒部１０がストツパ部材１３に係止
されるため、バンパがボデーフレーム１から脱落
する惧れがなくなるという効果を奏する。 Therefore, in the above embodiment, even if the elastic body 11 is peeled off from the bracket 6 or the pipe 12 due to cracks in the elastic body 11 or rust on the bracket 6 or the pipe 12 to which the elastic body 11 is vulcanized and bonded, the cylindrical portion of the bracket 6 remains intact. 10 is locked to the stopper member 13, there is no risk of the bumper falling off from the body frame 1.
また、自動車ボデーの振動及びバンパーの振動
は、それぞれ弾性体１１にて吸収され、それぞれ
の振動が共振することがなくなり、各部の振動が
互いに共振することなく、従来の共振モードが減
少するという効果を奏する。 In addition, the vibrations of the car body and the bumper are absorbed by the elastic body 11, and each vibration no longer resonates, and the vibrations of each part no longer resonate with each other, reducing the conventional resonance mode. play.
