本考案はヘッドやソファ−などのクッション体に使用さ
れるスプリング構体に関する。[Detailed Description of the Invention] The present invention relates to a spring structure used in a cushion body such as a head or a sofa.
たとえば、ベッドなどに使用されるマツトレスにおいて
は、主クッション体としてスプリング構体を使用し、こ
のスプリング構成の平面上にウレタンフオームなどから
なる弾性材を積層してクッション体全体を構成している
。For example, in a pinerest used for a bed or the like, a spring structure is used as the main cushion body, and an elastic material made of urethane foam or the like is laminated on the plane of this spring structure to construct the entire cushion body.
従来、上記主クッション体を構成するスプリング構体は
、多数のコイルばねを行列状に配置し、これらの端面を
行方向あるいは列方向にヘリカル線で連結するとともに
その平面の周辺部に枠線を取着してなる。Conventionally, the spring structure constituting the main cushion body has been constructed by arranging a large number of coil springs in a matrix, connecting the end faces of these springs with helical lines in the row or column direction, and with a frame line around the periphery of the plane. I'll wear it.
ところで、このような構成のスプリング構体に釦いては
、通常上記コイルばねが断面円形状をなした鋼線を曲成
して形成されている。By the way, in a button spring structure having such a configuration, the coil spring is usually formed by bending a steel wire having a circular cross section.
そのため、コイルばねは、その軸方向に荷重がカロわる
と鋼線にねじれが生じながら変形するので、このねじれ
によって復元力が発生し、復元力と荷重とが短時間でバ
ランスしてスプリング構体の振動が止むためクッション
性が良好である。Therefore, when a coil spring is loaded in its axial direction, the steel wire is twisted and deformed. This twisting generates a restoring force, and the restoring force and load are balanced in a short time and the spring structure is Good cushioning properties as vibration stops.
しかしながら、コイルばねに軸方向に列して直交する方
向に力が加わると、コイルばねほこの力に対して復元力
を生じることなく自然減衰する１で長時間にわたり揺れ
動くので、いわゆる横揺れによってスプリング構体の性
能低下を招くという欠点があった。However, when a force is applied to a coil spring in a direction perpendicular to the axial direction, the coil spring oscillates for a long period of time as it naturally attenuates without generating a restoring force against the force. This had the disadvantage of causing a decline in the performance of the structure.
本考案は上記事情にもとずきなされたもので、その目的
とするところは、コイルばねを用いず帯状鋼板で形成し
た主ばね体を主体にしてスプリング構体を構成すること
により、横方向から刃口わる力によって長時間にわたり
横揺れすることがないようにしたスプリング構体を提供
することにある。The present invention was developed based on the above-mentioned circumstances, and its purpose is to construct a spring structure based on a main spring body made of a strip steel plate without using a coil spring, so that it can be seen from the lateral direction. To provide a spring structure which is prevented from being swayed horizontally for a long time due to the force of the cutting edge.

な剛性を呈する。As mentioned above, in the present invention, the spring structure is constructed by providing a main spring body and a reinforcing spring body formed of a strip steel plate on the upper surface of a rectangular base. The spring part of the upper spring body and the reinforcing spring body are elastically deformed and exhibit good tension properties, and they also act like strips against forces applied in the transverse direction perpendicular to the thickness direction. The main spring body and the reinforcing spring body made of steel plates exhibit great rigidity.

積で確実に連結することができる。Therefore, the spring has less lateral vibration, that is, lateral vibration.The reinforcing spring body is connected to the horizontal part of the base plate and the main spring body, and both the reinforcing spring body and the main spring body are formed of a strip steel plate. This allows for reliable connection with a large contact area.

保たれる。Therefore, even if the spring structure is subjected to repeated loads, the connection between the main spring body and the reinforcing spring body will not easily shift, so the reinforcing function of the main spring body by the reinforcing spring body, that is, the cushioning properties of the spring structure, will last for a long time. Well kept.
