この発明はベッドやソファ−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 of a bed, sofa, etc.
たとえば、ベッドに使用されるボトムマツトレスや上部
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、このスプリング構体の平面上にウレタ
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 the bottom pinerest and upper pinerest used in beds, a spring structure is used as the main cushion body, and an elastic material such as urethane foam is laminated on the plane of this spring structure to form the entire cushion body. ing.
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.
すなわち、スプリング構体に加わる荷重をヘリカル線に
よって連結された複数のコイルばねに分散して、スプリ
ング構体の極部的な落ち込みをなくすようにしている。That is, the load applied to the spring structure is distributed to a plurality of coil springs connected by helical wires, thereby eliminating local depression of the spring structure.
しかしながら、このような構成によると、上記ヘリカル
線は、これ自体が荷重に対して大きく伸縮するばねであ
るため、荷重がたくさんのコイルばねに良好に分散され
ないという問題があった。However, with such a configuration, since the helical wire itself is a spring that expands and contracts significantly in response to a load, there is a problem in that the load is not well distributed among the many coil springs.
そこで、従来は、スプリング構体の局部的な落ち込みを
なくすためにコイルばねの配置密度を高め、荷重をでき
るだけ多くのコイルはねで受けるようにしていたが、こ
のような構成によると、１つのスプリング構体に使用す
るコイルばねの数が増大するので、スプリング構体のコ
スト上昇を招くことになる。Therefore, in the past, in order to eliminate local depressions in the spring structure, the arrangement density of coil springs was increased so that the load was received by as many coil springs as possible. Since the number of coil springs used in the structure increases, the cost of the spring structure increases.

A scale with a spring structure that does not undergo large local elastic deformation, or a highly rigid torsion part 7.
Since it is not necessary to provide the compression springs 4 at the locations corresponding to b, the arrangement density of the compression springs 4 can be made coarser.

でなく、たとえば水平部に対して３０度以上ねじれば、
水平部に比べて十分剛性を高めることができる。Further, although not shown, the twist angle of the twist portion formed in the connecting member relative to the horizontal portion is not limited in any way; for example, as long as it is twisted by 30 degrees or more relative to the horizontal portion,
The rigidity can be sufficiently increased compared to the horizontal part.

の部分に連結された圧縮はねによって弾性的に受けられ
る。As described above, the present invention uses a band-shaped steel plate as a connecting member that connects compression springs arranged at predetermined intervals, and connects a portion of the connecting member corresponding to the compression spring to a horizontal portion perpendicular to the compression direction of the compression spring. Since the connecting member is formed as a twisted part twisted with respect to the horizontal part, the connecting member hardly deforms because the torsion part has a large rigidity against the load, and has a lower rigidity than the torsion part. Small horizontal section deformations are taken up elastically by compression springs connected to this section.
したがって、圧縮ばねを密に配置しなくとも、圧縮ばね
の間に位置する連結部材のねじり部によってこの部分の
落ち込みが防止されるから、圧縮ばねの使用数を減らし
ても、スプリング構体の性能を十分確保することができ
る。Therefore, even if the compression springs are not arranged closely, the torsion part of the connecting member located between the compression springs will prevent this part from collapsing, so even if the number of compression springs used is reduced, the performance of the spring structure will be improved. Sufficient amount can be secured.
