という課題がある。In this conventional technique, the hardness of the upper and lower surfaces of the mattress device is made different by making the hardnesses of the first and second springs different from each other. Certainly, by varying the hardness of the spring, the hardness of the upper and lower surfaces of the mattress device will differ.
However, the user's feeling of being hard or soft is most affected by the portions that directly contact the user, that is, the elastic bodies provided on the upper and lower surfaces of each spring unit. In this prior art, if a relatively hard elastic body is provided, for example, on the upper and lower surfaces of the spring unit, the user can easily feel the hardness of the elastic body. There is a problem in that the difference in hardness cannot be expressed so much that the same feeling of hardness is received.

The load applied to the first elastic material 13 is relatively dispersed by the first elastic material 13 and applied to the first spring unit 1. The first spring unit 1 has coil portions 3a, 3b ... Of spring strips 2a, 2b ... And connecting portions 4a, 4b ... And these are continuous by one hard steel wire. The spring strips 2a, 2b, ... are made larger by increasing the area for receiving the load due to the fact that the coil portions are formed with each other, the adjacent coil portions are engaged with each other, and the number of coil portions is large. The amount of elastic deformation of the first spring unit 1 is reduced by elastically deforming the respective coil portions 3a, 3b ... Therefore, there is no local depression, and the load is applied to the entire first spring unit 1, and the user feels stiff.

り、利用者は硬い感触を受けることになる。The load applied to the first spring unit 1 is applied to the second spring unit 7. The number of single coil springs 8 ... Of the second spring unit 7 is smaller than that of the coil portions 3a, 3b ... of the first spring unit 1, and the coils of the spring strips 2a, 2b. Part 3a,
3b ... Are connected by the connecting portions 4a, 4b ..., but there is no connecting portion in the second spring unit 7. Therefore, the area receiving the load is smaller than that of the first spring unit 7, the elastic deformation amount is large, and the spring unit is softer than the first spring unit 7. In this case, the second spring unit 7 elastically deforms the entire body, but the first elastic member 13 and the first elastic member 13 close to the user are used.
Since the amount of elastic deformation of the spring unit 1 is small, the second spring unit 7 gradually elastically deforms while supporting the user hard, and the user feels a hard feeling. In particular, since the first elastic member 13 is relatively hard, the load is dispersed and transmitted to the first spring unit 1, and in addition to directly contacting the user to give a hard feeling, Due to the small elastic deformation amount of the first spring unit 1, the user feels hard.

る。On the contrary, when the user reclines on the upper surface side, the second elastic material 1 which is softer than the first elastic material 13 is first used.
5 receives the load. Since the second elastic material 15 is soft, the load cannot be dispersed. Therefore, the load applied to the second elastic material 15 is directly applied to the second spring unit 7 without being averaged as a whole. Since the coil springs 8 of the second spring unit 7 have a large elastic deformation amount, the elastic deformation amount of the second spring unit 7 increases and a local depression occurs, and the user feels soft. .

を受けることになる。The load applied to the second spring unit 7 is applied to the first spring unit 1, but the elastic deformation amount of the first spring unit 1 is smaller than that of the second spring unit 7, so that the second spring unit 7 sinks. Less crowded. In this case, the second spring unit 7 closer to the user first elastically deforms largely, and then the first spring unit 1 gradually elastically deforms slightly, so that the user feels soft. In particular, in addition to the second elastic member 15 directly contacting the user to give a soft feeling and transmitting the load to the second spring unit 7 without dispersing the load, the elastic deformation of the second spring unit 7 Due to the large amount, the user will feel soft.

きる。As described above, according to the present invention, a plurality of coil portions and a connecting portion for connecting the upper and lower ends of adjacent coil portions are continuously formed by one hard steel wire, A second coil unit formed by connecting a plurality of single coil springs in a flat plate shape on a first spring unit formed by connecting a plurality of spring strips formed by engaging a part of the coil unit with a part of an adjacent coil unit. Of the first spring unit, a relatively hard elastic material is laid on the other surface of the first spring unit, and a second elastic material softer than the first elastic material is provided on the other surface of the second spring unit. They were laid and covered with an exterior material. Therefore, in addition to the difference in hardness between the first and second elastic members that gives the user a direct feel of hardness, the difference in elastic deformation between the first and second spring units causes the upper surface side and the lower surface side. Since the hardness when used on the side is significantly different from the conventional one, it is possible to reliably provide a mattress device having a hardness according to the taste and physical condition of the user.
