本発明は金属板と樹脂とで構成した樹脂製はね部品に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a resin spring component made of a metal plate and resin.
従来、ばね部品には第１図ａ，ｂに示すようなコイルや
板ばねなどがある。Conventionally, spring components include coils and leaf springs as shown in FIGS. 1a and 1b.
これらは、ばねの機能を単独で有するために、何らかの
形で製品中に組込まねばならなかった。These had to be incorporated into the product in some way in order to have the function of a spring alone.
その際、コイルばねの場合には固定用のフックを必要と
し、また、板ばねの場合には固定用の台座を必要とする
。In this case, a coil spring requires a fixing hook, and a leaf spring requires a fixing pedestal.
また、はね自身の加工に多くの時間を必要とするばかり
でなく、ばね固定具の加工及びそれらの製品への組込み
にも多くの時間が必要である。Furthermore, not only does it take a lot of time to process the spring itself, but also a lot of time is required to process the spring fixture and incorporate it into the product.
本発明は、上記のような従来技術の欠点を解消し、ばね
部品、ばね固定具及び押圧部を樹脂で一体に成形して、
加工及び製品への組込み時間を大巾に短縮した樹脂製ば
ね部品を提供することにある。The present invention eliminates the drawbacks of the prior art as described above, and integrally molds the spring component, the spring fixture, and the pressing part with resin.
The purpose of the present invention is to provide a resin spring component that greatly reduces the time required for processing and assembling it into a product.
本発明は、金属板の貫通孔の周辺に樹脂で縁取り部を設
け、該縁取り部に一体に帯状の樹脂製ばね部を設け、か
つ該ばね部の先端に実質的に変形しない曲げの断面二次
モーメントを有する剛体状の押圧部を設けたことを特徴
とする。The present invention provides an edging section made of resin around a through hole in a metal plate, a band-shaped resin spring section integrally provided with the edging section, and a bending section having a bending shape that does not substantially deform at the tip of the spring section. The present invention is characterized in that a rigid pressing portion having a next moment is provided.
具体的には、第２図に示すように、金属板１の貫通孔２
の周辺に樹脂で縁取り部３を設け、該縁取り部３に一体
に、帯状の樹脂製はね部４を設け、かつ該ばね部４の先
端に実質的に変形しない曲げの断面二次モーメントを有
する剛体状の押圧部５を設けたものである。Specifically, as shown in FIG.
An edging part 3 is provided around the periphery of the resin, a band-shaped resin spring part 4 is provided integrally with the edging part 3, and a moment of inertia of bending that does not substantially deform is provided at the tip of the spring part 4. A rigid pressing portion 5 is provided.
ここで、金属板１の貫通孔２の周辺に設けた樹脂製の縁
取り部３は、金属板１に固定されているために、実質的
に変形しない剛体状の基体部分となる。Here, the resin-made edging portion 3 provided around the through hole 2 of the metal plate 1 is fixed to the metal plate 1, and thus becomes a rigid base portion that does not substantially deform.
この剛体状の基体部分に設置した帯状の樹脂製ばね部４
は柔軟で、ばね部４の先端に設けた押圧部５に力を加え
ると、押圧部５も剛体状であるので、ばね部４のみが、
基体に固定されている根元を中心に円弧状の運動をする
。A band-shaped resin spring part 4 installed on this rigid base part
is flexible, and when force is applied to the pressing part 5 provided at the tip of the spring part 4, since the pressing part 5 is also rigid, only the spring part 4
It moves in an arc around the base which is fixed to the base.
その際、押圧部５を第３図のように支持しておけば、支
持孔６と支持ピン７との遊びの範囲内で一方向の円弧運
動をさせることもできる。At this time, if the pressing part 5 is supported as shown in FIG. 3, it can be moved in a circular arc in one direction within the play between the support hole 6 and the support pin 7.
帯状の樹脂製ばね部４の構成としては、前述以外に、第
４図のように貫通孔内に設置し、金属板に垂直方向の円
弧運動をするようにしたもの、第５図のように金属板に
平行な方向の円弧運動をするようにしたものがある。In addition to the configuration described above, the band-shaped resin spring portion 4 may be installed in a through hole as shown in Fig. 4 and made to move in an arc perpendicular to the metal plate, or as shown in Fig. 5. There is one that moves in an arc in a direction parallel to the metal plate.
また、第６図ａのように、帯状の樹脂製ばね部４を縁取
り部３の対称の位置に２個所に設けてもよい。Further, as shown in FIG. 6a, the band-shaped resin spring portions 4 may be provided at two symmetrical positions on the edging portion 3.
これは、例えば、第６図ｂのような繰返し運動、第６図
Ｃのような精密運動に適している。This is suitable, for example, for repetitive movements as shown in FIG. 6b and precision movements as shown in FIG. 6c.
さらに、第７図のように、帯状の樹脂製はね部の形状を
断面コの字形にしてもよい。Furthermore, as shown in FIG. 7, the shape of the band-shaped resin spring portion may be U-shaped in cross section.
このようにすると、ばね部の柔軟性をコの字形全体で与
えているので、１本の帯状部分によってばねの柔軟性を
与える場合よりも、個々の部分の剛性を高くでき、強度
を向上できる。By doing this, the flexibility of the spring part is given by the entire U-shape, so the rigidity of each part can be made higher than when the flexibility of the spring is given by a single band-shaped part, and the strength can be improved. .
さらに、縁取り部と樹脂製ばね部のつけ根および押圧部
と樹脂製はね部のつけ根の局部曲率半径を１ｍｍ以上に
すると、第８図に示す局部曲率半径Ｒをパラメータとす
る繰返し回数Ｎと応力振幅Ｓの関係のグラフのように、
強度が高くなり、耐久性が良好となる。Furthermore, if the local radii of curvature at the base of the edging part and the resin spring part and the base of the pressing part and the resin spring part are set to 1 mm or more, the number of repetitions N and the stress using the local radius of curvature R shown in FIG. Like the graph of the relationship between amplitude S,
It has high strength and good durability.
本発明によれば、他の部品を係止する為のばね部品を金
属板上のばね固定具と一体に成形できるという効果があ
る。According to the present invention, there is an effect that a spring component for locking other components can be integrally molded with a spring fixture on a metal plate.
本発明によれば、基体部分、ばね部、押圧部を樹脂で一
体に成形できるので加工及び組立工程が著しく短縮され
、生産性が大巾に合理化される。According to the present invention, since the base portion, the spring portion, and the pressing portion can be integrally molded from resin, processing and assembly steps are significantly shortened, and productivity is greatly streamlined.
とくに、基体部分は金属板と樹脂の複合成形品であるの
で、繰返し力の作用による基体部分の変形が少なくてす
む。In particular, since the base portion is a composite molded product of a metal plate and resin, deformation of the base portion due to repeated forces is reduced.
