BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a mattress device used for beds and the like.

[0002]

2. Description of the Related Art Generally, in a mattress device, a large number of coil springs are arranged in a matrix to form a rectangular spring unit, and elastic materials are laminated in a sheet shape on at least the upper and lower surfaces of the spring unit. The laminated body is covered with a cloth exterior body sewn in a bag shape. The upper and lower peripheral portions of the spring unit have a frame wire formed of a hard wire material in order to reduce the coupling degree of the coil springs, to reinforce the peripheral coil springs, and to maintain the outer shape of the mattress device. Is provided.

The mattress device having such a structure is used by being placed on a floor plate provided on a base of a bed. Beds include so-called wake-up beds that are used by people who have difficulty getting up by themselves, such as the sick and the elderly.

The floor plate of the wake-up bed is divided into a plurality of divided pieces, and each divided piece is rotatably provided on the base body. Each of the divided pieces is rotationally driven by a driving device, and thereby the floor plate is undulated. Therefore, the user lying on the floor plate via the mattress device can raise the upper body, for example, by the undulating floor plate.

Therefore, the mattress device used for such a wake-up bed must be constructed so as to be bent in accordance with the ups and downs of the divided pieces of the floor plate.
However, as described above, a mattress device including a spring unit in which frame lines are provided on the peripheral portions of the upper and lower surfaces is hard to be bent depending on the ups and downs of the floor plate because the frame line is hard.

In order to make the spring unit easier to bend, the frame lines provided on the upper and lower peripheral portions of the spring unit may be removed or formed of a soft wire. However, if the frame line of the spring unit is removed or formed of a soft wire, the peripheral portion of the spring unit becomes too soft, which reduces the effective use area of the mattress device and impairs the outer shape.

[0007]

As described above, in the conventional mattress device used for the wake-up bed, since the frame lines are provided on the upper and lower peripheral edges of the spring unit,
It was difficult to bend it.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a softness that can be easily bent and to prevent the peripheral portion of the spring unit from becoming too soft. It is to provide a mattress device.

[0009]

According to the present invention as set forth in claim 1, springs are arranged in a rectangular shape to form a spring unit, and an elastic material is laminated on at least the upper and lower surfaces of the spring unit. A mattress device in which the laminated body is covered with an exterior body is characterized in that the spring unit is formed to be bendable.

According to a second aspect of the present invention, the springs are arranged in a rectangular shape to form a spring unit,
In a mattress device in which an elastic material is laminated on at least the upper and lower surfaces of this spring unit and the laminated body is covered with an exterior body, the spring unit is bendable at a predetermined position in the longitudinal direction of the spring unit. It is characterized in that a flexible portion is formed.

[0011]

According to the above construction, since the spring unit can be easily bent, the spring unit can be easily bent in accordance with the ups and downs of the floor plate by using the spring unit, for example.
