この考案は、固定板の長孔の所定位置に締付は固定され
るボルトの固定構造に関する。[Detailed Description of the Invention] This invention relates to a bolt fixing structure that is tightened and fixed at a predetermined position in a long hole of a fixing plate.
従来、この種ボルトの取付けにおいては、特公昭５０−
２９１０涛公報にも示されているように、通常ボルト側
やナツト側にワッシャを介在させており、固定板の長孔
にボルトを締付は固定するものにあっては、前記長孔に
ボルト軸を挿通し、かつその長孔の所定位置でワッシャ
を介してナツトにより締付けてなる構成を有するものが
ほとんどである。Conventionally, in the installation of this type of bolt, the
As shown in the No. 2910 publication, a washer is usually interposed on the bolt side or nut side, and if the bolt is tightened and fixed in the long hole of the fixing plate, the bolt is inserted into the long hole. Most of them have a structure in which a shaft is inserted through the long hole and tightened with a nut through a washer at a predetermined position in the elongated hole.
しかしながら、このような従来構造のものでは、固定板
に穿設された長孔が単に長手方向に等幅な帯状であるこ
とから、ナツトが多少とも緩むと、衝撃等による大きな
振動を受けると、取付位置がズレ易いなどの不具合があ
った。However, in this type of conventional structure, the long holes drilled in the fixing plate are simply band-shaped with equal width in the longitudinal direction, so if the nut loosens to some extent or receives large vibrations due to impact, etc. There were problems such as the installation position being easily misaligned.
この考案は、上記した従来構造の欠点を解消することを
目的としたもので、以下、図示の実施徊に基づいて説明
する。This invention is aimed at solving the above-mentioned drawbacks of the conventional structure, and will be explained below based on the illustrated implementation.
第１図から第４図に示すように、図中１は固定板である
。As shown in FIGS. 1 to 4, numeral 1 in the figures represents a fixing plate.
該固定板１には、長孔２が穿設されていて、該長孔２は
、複数個の同形の透孔、例えば真円の円孔２１を長手方
向に互いにオーバーラツプさせて配列した波形状の連続
打抜き孔からなる。A long hole 2 is bored in the fixing plate 1, and the long hole 2 has a wavy shape in which a plurality of holes 21 having the same shape, for example, perfectly circular holes 21 are arranged overlapping each other in the longitudinal direction. Consists of continuous punched holes.
そして、図中３は、前記固定板１の長孔２の所定位置に
挿通されるボルトで、その軸３１の径は、前記長孔２を
形成する隣接した円孔２１がオーバーラツプする狭幅部
２ａの幅よりも僅かに小さい近接した径を有し、これに
よって該ボルト軸３１が長孔２の長手方向に沿って移動
自在となっているとともに、ワッシャ４，５及びナツト
６により締付は固定されるようになっている。Reference numeral 3 in the figure denotes a bolt that is inserted into a predetermined position of the elongated hole 2 of the fixing plate 1, and the diameter of its shaft 31 is a narrow portion where the adjacent circular holes 21 forming the elongated hole 2 overlap. 2a, the bolt shaft 31 is movable along the longitudinal direction of the elongated hole 2, and is not tightened by the washers 4, 5 and the nut 6. It is set to be fixed.
さらに、図中７及び８は前記固定板１の表裏面と各々の
ワッシャ５，６との間に介在されたゴム等の弾性材また
は易塑性変形金属などからなる円筒状のリング体でその
径は前記円孔２１の径よりも大きくなっている。Furthermore, 7 and 8 in the figure are cylindrical ring bodies made of an elastic material such as rubber or easily deformable metal, which are interposed between the front and back surfaces of the fixing plate 1 and the respective washers 5 and 6. is larger than the diameter of the circular hole 21.
すなわち、上記した固定板１の長孔２の所定位置にボル
ト３を取付けるには、まずボルト軸３１にワッシャ４及
びリング体７を挿着して固定板１の表面側から長孔２に
挿通し、そのボルト軸の挿通端部３１ａにリング体８及
びワッシャ５を挿着した後、ナツト６を螺合させてなる
もので、該ナツト６の締付作用で前記リング体７，８は
弾性または塑性変形して圧潰され、それらの一部７ａ及
び８ａが前記長孔２の円孔２１の広幅部２ｂと狭幅部２
ａの双方をまたぐように長孔内に喰い込ませてなる構成
を有するものである。That is, in order to attach the bolt 3 to a predetermined position in the elongated hole 2 of the fixing plate 1 described above, first insert the washer 4 and the ring body 7 into the bolt shaft 31 and insert it into the elongated hole 2 from the surface side of the fixing plate 1. After inserting the ring body 8 and the washer 5 into the insertion end 31a of the bolt shaft, a nut 6 is screwed together.The tightening action of the nut 6 makes the ring bodies 7 and 8 elastic. Or they are plastically deformed and crushed, and the parts 7a and 8a are the wide part 2b and the narrow part 2 of the circular hole 21 of the elongated hole 2.
It has a structure in which it is cut into a long hole so as to straddle both sides of the hole.
したがって、上記のこの考案に係る構成によれば、ボル
トが所定の位置で挿通固定される固定板の長孔を、長手
方向に向は複数の広幅部と狭幅部とからなる連続孔形状
に形威し、かつ該長孔内に弾性または塑性変形によりリ
ング体の一部を喰い込ませるようにボルト軸をナツトで
締付けてなることから、リング体の喰い込みによりボル
ト軸の長孔長手方向のズレが確実に防止され、しかもボ
ルト軸の位置合せによる取付けも簡便にできるなど、実
用性にすぐれた効果を奏するものである。Therefore, according to the above-mentioned configuration according to this invention, the long hole of the fixing plate through which the bolt is inserted and fixed at a predetermined position is formed into a continuous hole shape consisting of a plurality of wide width parts and a plurality of narrow width parts in the longitudinal direction. The bolt shaft is tightened with a nut so that a part of the ring body is bitten into the elongated hole by elastic or plastic deformation. This has excellent practical effects, such as being able to reliably prevent misalignment of the bolts, and also making it easy to install by aligning the bolt shafts.
