One end of a compression spring 24 is engaged with the other end of the receiving member 23. At the other end of the compression spring 24, a disc-shaped connecting tool 25 is provided, and the end of the steel wire 19 inserted into the through hole 23b is connected and fixed to the connecting tool 25. That is, the end of the steel wire 19 is connected and fixed to the connecting tool 25 while the compression spring 24 is compressed.

トレス１２が載置される。A sheet-like cushion member 26 is laid on the upper surface of the upper frame portion 14 on which the steel wire 19 is stretched as described above. The upper surface of the cushion material 26 and the base 11
Is covered with an exterior ground 27. Then, the mattress 12 is placed on the upper surface of the exterior ground 27 as shown in FIG.

ら、上記鋼線１９に伸びが生じることになる。According to the base 11 of the bed 10 having the above-described structure, the use state in which the user lies on the mattress 12 is repeated, so that the load is repeatedly applied to the steel wire 19 elastically supporting the mattress 12. Therefore, the steel wire 19 elongates.

い。When the steel wire 19 is extended, the compression spring 24 is also extended by the restoring force in accordance with the extension.
Is pulled in the direction indicated by the arrow in FIG. 1, and its elongation is absorbed. Accordingly, the steel wire 19 is maintained at a substantially constant tension without sagging.
The support state of the mattress 12 is not impaired.

びを少なくすることができる。Further, since the compression spring 24 is used to absorb the slack of the steel wire 19, even if the compression spring 24 is bent over a long period of use, the steel wire 19 is slackened more than its maximum compression length. I don't have to. In other words, if a tension spring is used in place of the compression spring 24, when the tension spring is bent, the spiral of the spring will be extended, so that the extension of the steel wire 19 becomes very large. Thus, the extension of the spring 24 when it is bent can be reduced.

ばねを介して枠部に保持するようにしてもよい。The present invention is not limited to the above-described embodiment, but can be variously modified without departing from the gist of the invention. For example, in the above embodiment, only one end of the steel wire is held by the frame via the compression spring, but both ends may be held by the frame via the compression spring.

Furthermore, the user may directly lie on the upper surface without placing the mattress on the upper surface of the base.

とができるなどの利点を有する。Therefore, if the steel wire elongates during use, the compression spring in a compressed state expands to absorb the elongation of the steel wire, so that the steel wire is prevented from sagging. Can be. Moreover, even if the compression spring is sagged, the steel wire will not sag more than its maximum compression dimension, so that the elongation of the steel wire when the spring is sagged is reduced as compared with the case where a tension spring is used. It has advantages such as being able to.
