2. Description of the Related Art Generally, a mattress device has a spring unit formed by connecting a large number of coil springs in a matrix, and a padding such as synthetic cotton or urethane foam is laminated on the spring unit. . This laminate is covered with an exterior body formed of a mirror portion and a town portion.

In the mattress device having such a configuration, the padding is connected and fixed to the spring unit with a large number of clips in order to prevent the padding from moving relative to the spring unit. Further, in order to prevent the exterior body from moving relative to the spring unit, one end is connected and fixed to the inner peripheral portion of the mirror section to provide a flange cloth, and the other end of the flange cloth is connected to the peripheral section of the spring unit. As in the case of the padding, they are connected and fixed by clips.

According to such a configuration, the padding is prevented from being displaced by the clip and the flange cloth, and the exterior body is prevented from being displaced by the flange cloth.

[0005] However, when the mattress device is damaged due to long-term use and must be discarded, recently, the waste can only be collected by disposing the material for each material type. In many areas, the system is adopted. When the mattress device is discarded in an area where separate collection is being performed, the spring unit, which is a metal part, and the padding and the outer casing made of synthetic cotton or the like must be discarded separately.

In this case, if the padding is connected to the spring unit by a large number of clips, it is not easy to remove the padding from the spring unit, and similarly, it is not easy to remove the outer package from the spring unit. Therefore, the disassembly work at the time of disposal may take a lot of trouble.

[0007]

As described above, in the conventional mattress device, the padding is connected to the spring unit with a large number of clips, and the exterior body is also connected to the spring unit with a clip via a flange cloth. In the case where each material must be separated at the time of disposal, the disassembling operation is troublesome.

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to hold and fix a padding and an exterior body to a spring unit without using a large number of clips, thereby facilitating disassembly. It is an object of the present invention to provide a mattress device capable of performing the above-mentioned.

[0009]

According to the present invention, there is provided a mattress device comprising: a spring unit having an upper surface and a lower surface;
An outer package having a padding stacked on the upper and lower surfaces of the spring unit, a mirror portion covering the upper and lower surfaces of the stacked body of the padding and the spring unit, and a town portion covering the outer peripheral surface, respectively; A pair of upper and lower flange cloths, one ends of which are connected to the inner peripheral part, and both end parts are respectively connected to the other end parts of the pair of upper and lower flange cloths on the outer peripheral surface of the spring unit formed of a shape memory alloy. Is provided partially in the circumferential direction,
And a connecting member that imparts tension to the flange cloth by being deformed by heating.

[0010]

According to the above construction, tension can be applied to the flange cloth by heating the connecting members connected to the other ends of the pair of upper and lower flange cloths at the time of assembling. The exterior body can be fixed to the spring unit. At the time of disassembly, the exterior body and the padding can be separated from the spring unit only by cutting and removing the portion of the flange cloth to which the connection member is connected and removing the connection member from the flange cloth.
