[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to an improvement in a mattress device used for a bed or the like.

[0002]

2. Description of the Related Art In general, a mattress device has a plurality of coil springs arranged in a matrix to form a rectangular spring unit, and an elastic material is laminated on at least the upper and lower surfaces of the spring unit in a sheet shape. The laminated body is covered with a cloth outer body sewn in a bag shape.

[0003] In the mattress device having such a configuration, a user lying on the upper surface of the mattress device can be supported without bending the back muscle, which is the heaviest part of the human body, into the spring unit. Performance is required.

In order to satisfy such performance, the spring unit is hardly compressed and deformed against a load,
It has been practiced to constitute a so-called hard coil spring.

If a hard coil spring is used, compression deformation of a portion corresponding to the user's buttocks, which receives a large load of the spring unit, can be reduced, and it is possible to prevent the buttocks from dropping largely into the spring unit. it can. However, if the spring unit is formed of a hard coil spring, when the user goes to bed in a horizontal position, the shoulder of the user is strongly pressed by the repulsive force of the hard coil spring, resulting in numbness in the shoulder. , It may make you feel uncomfortable.

[0006] Further, when the user rolls sideways from the back on the spring unit formed by the hard coil spring, the shoulder portion receives a strong repulsive force of the coil spring, so that the roll over occurs. Sometimes it ’s hard to beat. In particular, in the case of elderly or sick people with weak physical strength, the coil spring may not be able to roll over on its own due to the strong repulsion. Sometimes it is invited.

[0007]

As described above, in the conventional mattress device, if the spring unit is formed of a hard coil spring in order to support the user's body without the buttocks falling down, a horizontal sleeping posture is obtained. When taking it, the shoulder part may be strongly pressed and the sleeping comfort may be reduced, and for people with weak physical strength, when turning over from the supine state to the side, the shoulder part receives a large repulsive force and turns over Sometimes it was hard to beat.

[0008] The present invention has been made based on the above circumstances, and its purpose is to provide a user with a rigidity capable of supporting the user without the buttocks falling down and to have a horizontal posture. An object of the present invention is to provide a mattress device in which a shoulder portion is not strongly pressed even when taken, and furthermore, it is easy to roll over from a supine state to a sideways state.

[0009]

In order to solve the above-mentioned problems, the present invention is to form a spring unit by arranging a large number of coil springs in a matrix, and to form a spring unit on at least the upper and lower surfaces of the spring unit. In a mattress device in which materials are laminated and the laminated body is covered with an exterior body, a coil spring at one end in the longitudinal direction of the spring unit is softer than coil springs at other portions.

[0010]

According to the above construction, the user can place the shoulder portion on the soft coil spring portion of the spring unit so that the buttocks can be supported without dropping by the hard coil spring portion, and can be turned sideways from that state. When taking a posture, the shoulder part compresses the soft coil spring, so it does not receive a strong repulsive force, and when you roll from the back up to the side, the shoulder part compresses the soft coil spring Easy to hit.

[0011]

An embodiment of the present invention will be described below with reference to the drawings.

The mattress device M shown in FIGS. 1 and 2 has a spring unit 1. The spring unit 1 is formed by arranging a large number of coil springs 2 in a matrix to form a rectangular shape, and connecting upper and lower end surfaces of the coil springs 2 adjacent in the width direction by helical wires 3.

FIG. 1 shows one end of the coil spring 2 constituting the spring unit 1 in the longitudinal direction.
The range indicated by A in FIG.
When the head is positioned on one end side of the user and the patient is supine, the coil spring 2a of the portion corresponding to the shoulder of the user is formed softer than the coil spring 2 of the other portion. In order to make the coil spring 2a in the range A softer than the coil springs 2 in the other parts, for example, the coil spring 2a may be formed of a thinner wire or a softer wire than the other coil springs 2.

On the upper and lower surfaces of the spring unit 1, a sheet-like elastic material 5 made of urethane foam or the like is laminated via a protective material 4, and a side reinforcing material 6 is provided on the outer peripheral portion. It is provided over the entire circumference. This side reinforcement 6 is provided by in-situ foaming.

That is, as shown in FIG. 4, before the protective member 4 and the elastic member 5 are laminated on the upper and lower surfaces of the spring unit 1, a shielding sheet 7 is provided over the entire outer peripheral surface of the spring unit 1. Over. Then, after the protective member 4 and the elastic member 5 are laminated on the upper and lower surfaces of the spring unit 1, the spring unit 1 is put in a mold 11 and the mold 11 is covered with a lid 12. The urethane stock solution is injected into the foaming space 13 formed between the inner peripheral surface of the spring unit 1 and the outer peripheral surface of the spring unit 1 from the injection hole 14 formed in the side wall of the mold 11 and foamed on site. The side reinforcing member 6 is formed.

As shown in FIG. 3, the side reinforcing member 6 is a coil spring 2 which is located around the coil spring 1.
And a cover 6b for covering the outer peripheral surface of the spring unit 1 between the upper and lower end surfaces 2a. Therefore, the protrusion 6a reinforces and hardens the coil spring 2 located at the periphery of the spring unit 1,
The covering portion 6b adjusts the outer shape of the mattress M,
It gives a soft feel.

The spring unit 1 in which the side reinforcing members 6 are provided on the outer peripheral surface and the elastic members 5 are laminated on the upper and lower surfaces via the protective members 4 is covered with the exterior body 8.
This exterior body 8 is a mirror ground 8a covering the upper and lower surfaces of the spring unit 1, and a town ground 8b covering the outer peripheral surface and having upper and lower ends sewn to the peripheral edge of the mirror ground 8a by a tape 9.
Consists of

When using the mattress device configured as described above, the user lies with his head positioned at one end of the spring unit 1 in which the soft coil spring 2a is incorporated. As a result, the shoulder of the user is located in the area A where the soft coil spring 2a is provided, and the buttocks are located in the area of the hard coil spring 2 other than the area A.

Since the shoulder is lighter than the buttocks, even if the coil spring 2a supporting the portion is soft, it hardly falls into the spring unit 1, and the buttocks are supported by the hard coil spring 2. Therefore, that part does not fall into the spring unit 1 greatly. That is, even if the coil spring 2a in the range A of the spring unit 1 is softened,
The buttocks of the lying user can be supported without sinking deeply into the spring unit 1.

When the user takes a horizontal lying posture from the back, the shoulder compresses the coil spring 2a in the range A. Since the coil spring 2a in this portion is relatively soft, its repulsive force is not so large. Therefore, the user's shoulder portion is not strongly pressed, so that the sleeping comfort in the sideways direction is improved.

Further, when the user changes the body direction for turning over from the supine position to the side position, the soft coil spring 2a in the range A is compressed by the shoulder, so that it is relatively easy. You can change the direction. In other words, even an elderly or sick person whose physical strength has declined can easily change its direction by himself, which may be effective in preventing floor congestion.

In the mattress device M having the above-described structure, in order to reinforce the coil spring 2 in the periphery of the spring unit 1, a side reinforcing material 6 made of urethane foam is used without using a frame as in the prior art. Was used. For this reason, since the mattress device M has flexibility, for example, if the mattress device M is used for a wake-up type bed, the mattress device M can be bent in accordance with the rise when a part of the floorboard is raised. Sometimes.

FIG. 5A shows a conventional spring unit 1.
X, the entire spring unit 1X was formed of a relatively soft coil spring 2. In this case, when the user lies on the spring unit 1, the heaviest buttocks of the user's body fall more greatly than other parts, so that a correct sleeping posture in which the back muscles are stretched cannot be obtained.

FIG. 2B shows a state in which the user lies on the spring unit 1 of the present invention, and only the area A corresponding to the shoulder of the user U is made softer than the other parts, so that the buttocks are reduced. Not only can a large drop be prevented, but the shoulder is not as heavy as the buttocks, so even if the coil spring 2a in that portion is soft, the shoulder does not fall.

FIG. 3C shows a state in which the user is lying on the spring unit 1 of the present invention. In this case, the shoulder portion S of the user U compresses the portion of the range A of the coil spring 2 of the spring unit 1, that is, the soft coil spring 2a, so that the shoulder portion receives the strong repulsive force of the coil spring 2a. There is no.

In the above embodiment, the coil spring 2a in the range A of the spring unit 1 is softened to remove the coil spring 2 in the periphery of the spring unit 1. The entire coil spring 2 on one end side in the longitudinal direction, including the above coil spring, may be made softer than the coil springs of the other portions.

[0027]

[Effects of the Invention] As described above, this invention uses a coil spring at one end in the longitudinal direction of a spring unit.
Made softer than other parts of coil spring.

Therefore, when the user takes a horizontal lying posture, the shoulder portion compresses the soft coil spring, and the shoulder portion can reduce the repulsive force received from the coil spring. Sleeping comfort can be improved. Furthermore, even when the user rolls over from a supine position to a lateral position, the compression is performed while compressing the soft coil spring. The bed can be turned over, thereby preventing bedsores.
