The other end is wound around the periphery of the padding and connected and fixed to the periphery of the spring unit by a number of clips. According to such a configuration, the padding and the outer package are connected and fixed to the spring unit by rip-stopping with a fabric cloth. .

When such a mattress device is used for a long period of time, even if the spring unit formed of hard steel wire can be used satisfactorily with almost no set or damage, it is possible to use woven cotton or urethane foam. -The padding made of elastic material such as rubber may cause a large set, damage to the exterior body such as wear or dirt, etc. You may not be able to do so.

[0005] As described above, in the case where the spring unit can be used sufficiently even after long-term use, but the padding and the outer casing are damaged, the mattress device cannot be used. In the apparatus, since the exterior body is fastened to the spring unit by a large number of clips via the flange cloth, it takes a lot of time to remove the exterior body from the spring unit, and the mirror section and the town section are tapered. By sewn together with the tape to form an exterior body, etc., the stuffing or exterior body damaged at the place where the customer is using is separated from the spring unit, and a new stuffing is used for the spring unit. Laminating, covering the laminated body with a new exterior body formed in advance at a factory, etc., and reassembling it into a new mattress device More, it was not possible to inexpensively formed in comparison with the new mattress apparatus by reducing the transportation costs with measuring the effective utilization of resources. In addition, a system in which the mattress device that can no longer be used is sent to the factory, reassembled as described above, and sent to the customer again can be considered, but even in this case, the labor and transportation costs are increased and the cost is increased. In the current situation, the mattress device has been disposed of.

However, in order to dispose of the mattress device, it is necessary to divide the mattress device into small pieces because the volume of the mattress device is large, or to separate the spring unit, which is a metal part, from the stuffing or the sheath made of synthetic cotton and the like. It must be discarded, and in the disassembly work, the work of removing the clip securing the padding and the outer body to the spring unit from the spring unit must be performed. However, removing the clip requires a special tool and is very troublesome, and it is impossible to disassemble it in a general household, and even if it is attempted to disassemble it in a factory, it requires a great deal of labor.
