Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mattress device having a plurality of cushioning effects by a plurality of layers of cushioning bodies.

[0002]

[Prior art]

 In general, a mattress device is configured by connecting a number of coil springs in a matrix to form a spring unit, superposing elastic materials on the upper and lower surfaces of the spring unit, and covering them with an exterior body. . Therefore, the mattress device having such a structure has only a single cushioning property, which is not sufficient for obtaining a good sleeping posture.

Generally, there is a bed apparatus in which a bottom mattress is provided and the mattress is placed on the upper surface. This bottom mattress tries to absorb the vibration and roll of the mattress on the top surface, but the cushion is not continuous due to the separate mattress device, so that the user's sleeping posture can be maintained well. It wasn't enough to do it.

[0004]

[Problems to be solved by the device]

 As described above, the conventional mattress is not sufficient to maintain the sleeping posture of the user with a single cushioning effect.

The present invention has been made in view of the above circumstances, and an object thereof is to maintain a good sleeping posture of a user by providing a plurality of cushion effects with a plurality of layers, particularly three or more layers of cushion bodies. It is to provide a mattress device.

[0006]

[Means for Solving the Problems]

 In this invention, a cushion body having a plurality of layers is polymerized, and each cushion body is a cushion body which is sequentially softer than the lower layer as it becomes an upper layer, and is provided with an exterior body covering these plurality of cushion bodies. Each of the above cushion bodies is formed of a spring unit in which a large number of coil springs are connected in a matrix.

[0007]

[Action]

 The cushion body of the first layer keeps a natural sleeping posture while fitting the movement and unevenness of the user's body, the cushion body of the second layer evenly distributes the body pressure, and the cushion body of the third layer The body absorbs vibration and shaking.

[0008]

【Example】

 A first embodiment of the present invention will be described below with reference to FIGS. In the mattress device shown in FIGS. 1 and 2, the first layer spring unit 1, the second layer spring unit 2 and the third layer spring unit 3 are superposed from the top.

The wire diameter (thickness of wire) of each spring 11 constituting the first layer spring unit 1 is smaller than that of each spring 21 constituting the second layer spring unit 2, The wire diameter of each spring 21 forming the eye spring unit 2 is smaller than the wire diameter of each spring 31 forming the third layer spring unit 3. That is, the amount of elastic deformation for the same load is set so that the coil spring of the first layer is larger than the coil spring of the second layer, and the coil spring of the second layer is set larger than the coil spring of the third layer. ing.

Each spring unit 1, 2, 3 is formed by arranging a large number of coil springs in a matrix and connecting the upper and lower end faces of adjacent coil springs 11, 21, 31 with helical wires 12, 22, 32. In addition, a partition plate 4 made of sisal pad or foamed elastic material is present on the surface where the spring units 1, 2 and 3 overlap with each other, and an unpleasant sound is generated when the spring units 1, 2, 2 and 3 collide with each other. Is being prevented.

On the upper surface of the spring unit 1 and the lower surface of the spring unit 3, a protective material 5 made of sisal pad or foamed elastic material is polymerized, and these are covered with an exterior body 6.

In this embodiment, the coil springs of the second and third layers have the same height other than the wire diameter, the diameter of each coil portion, the winding pitch, the material, etc. The wire diameter of the coil spring is larger than that of the coil spring of the second layer, and the coil spring of the first layer is thinner than that of the coil spring of the second layer. The height of the spring is smaller than that of the second layer, and the number of springs is set to a large number when it is used as a spring unit.

That is, the spring unit 1 of the first layer has a high spring density and is configured as a soft cushion body, which is set so as to be easily adapted to the unevenness of the user's body. The cushion of the spring unit 2 of the second layer is harder than the cushion of the spring unit 1 of the first layer, that is, the amount of elastic deformation is smaller. Therefore, the spring unit 2 of the second layer supports the entire spring unit 1 of the first layer, which is in conformity with the irregularities of the user's body, to evenly distribute the body pressure of the user. become. The cushion of the spring unit 3 of the third layer is harder than the cushion of the spring unit 2 of the second layer, that is, the amount of elastic deformation is smaller. Therefore, the spring unit 3 of the third layer supports the entire spring units 1 and 2 so as to prevent vibration and roll due to the user's use.

With such a configuration, the spring unit of the first layer keeps a natural sleeping posture while fitting the movement and unevenness of the user's body, and the spring unit of the second layer equalizes body pressure. The third-layer spring unit can absorb vibrations and rolls.

FIGS. 4 to 7 show a second embodiment. In this embodiment, the wire diameters of the coil springs of the respective layers are different, and the elastic deformation amount for the same load is set large toward the upper layers sequentially. That is, the softening is the same as in the above embodiment. The feature of the present invention is that each of the coil springs of the first layer is arranged between the coil springs of the second layer which are in contact with each other, and each of the coil springs of the second layer is similarly arranged. Means that it is located between the coil springs that are in contact with the third layer of phosphorus.

Each of the first-layer springs 11, 11, ... Is disposed substantially in the middle of each of the second-layer springs 21, 21 ,. Each of them is arranged substantially in the middle of each of the third layer springs 31, 31, .... That is, the coil spring of the upper layer spring unit exists in the portion where the coil spring of the lower layer spring unit does not exist, and there is a spring without a gap when seen in a plane as seen in FIG. They are in a complementary relationship.

Synthetic resin foams 7 and 8 are arranged at the side ends of the second-layer spring unit 2 and the third-layer spring unit 3 to reinforce the strength of the entire side of the mattress device. Plays a role to do.

FIG. 5 is a perspective view in which a part of the second embodiment is cut away, and a cross-sectional view taken along arrow A is shown in FIG. 6A, and taken along arrow B. A cross-sectional view of is shown in FIG. 6 (b).

FIG. 7 shows the relationship between the springs of the spring units 1, 2, and 3. In FIG. 7A, the coil springs 21, 21 ... And the coil springs 31, 31 ... Are displaced from each other, and FIG. Shows that the coil springs 21, 21, ... And the coil springs 11, 11, ... Are arranged so as to be offset from each other.

In the above embodiment, the wire diameters of the coil springs of the respective layers are made different so that the elastic deformation amount for the same load is set to be large toward the upper layer in order, that is, the elastic deformation is made softer. In order to make the elastic deformation amount different, even if the coil spring wire diameter of each layer is the same, the elastic deformation amount should be made different by increasing the number of spring turns or increasing the winding diameter. You can
