0003 Therefore, the cushioning performance of a mattress device with such a configuration is This is greatly influenced by the performance of the coil spring that forms the ring unit. It becomes.

0004 The cushioning performance of the mattress device is, for example, when the user lies down. In addition, it has a softness that supports the user through large elastic deformation under the load, and a Supports the buttocks, which is the heaviest part of the user's body, so that it does not slump locally. It is required to have both hardness and hardness.

[0005] However, forming a mattress device with only one spring unit If this is done, there will be a limit to the flexibility that can be provided to the user. Therefore, it is necessary to provide sufficient Two spring units are used to create a feeling of softness. A so-called double-cushion type mattress device was proposed, which is a polymerized It is.

[0006] According to the double cushion type mattress device, deformation under load Since the amount is large, the user can feel good softness. deer However, as the mattress device becomes softer, the heavier parts of the user's body become lighter. The local depression of the buttocks becomes large. As a result, the user's sleeping posture If you do this, your spine will be greatly curved downwards, so you should keep your back straight and in good condition. There were cases where the sleeping position could not be maintained, leading to a decrease in sleeping comfort.

[0007]

[Problem that the idea aims to solve]

In this way, double-click the mattress device to obtain soft cushioning performance. If it is a cushion type, the local depression of the heavy part of the user's body will be large. This can lead to poor sleeping posture and decreased comfort.

[0008] This idea was made based on the above circumstances, and its purpose is to When using the bull cushion type, the heavy parts of the user's body will not be significantly dropped locally. To provide a mattress device capable of preventing sinking.

[0009]

[Means to solve the problem]

In order to solve the above problem, this idea connects coil springs in a matrix. polymerizing the formed first spring unit and second spring unit; In a mattress device constructed by integrally covering this polymer with an exterior body, A central portion in the longitudinal direction of the first spring unit and the second spring unit is a coil spring that deforms less under load than other coil springs. It is characterized by being formed by a ring.

0010

[Effect]

According to the above configuration, it is possible to improve the action performance by using double action. and the first spring unit and the second spring unit. Since the central part in the longitudinal direction is harder than other parts, it is not supported by that central part. It is possible to prevent the heavy parts of the user's body from dropping significantly locally. .

【Example】 An embodiment of this invention will be described below with reference to the drawings.

0012 The mattress device shown in FIG. 1 has a first spring unit 1 . This first The spring unit 1 has a large number of coil springs arranged in a matrix by helical wires 2. It is formed by connecting in a shape. That is, the first spring unit 1 is The coil springs include a first coil spring 3 and a second coil spring 4. It is formed from. The first coil spring 3 is the second coil spring 4 The wire is made of hard steel wire with a thick wire diameter so that it deforms less under load than the Therefore, it is formed.

[0013] The area indicated by A in FIG. 1 of the first spring unit 1, that is, the center in the longitudinal direction The part is formed by the first coil spring 3 and is the other part. Both end portions indicated by B in FIG. 1 are formed by the second coil spring 4. Ru.

[0014] A second spring unit 5 is fitted to the first spring unit 1 having the above configuration. Polymerization is performed via a partition sheet 6 made of a net-like body made of synthetic resin. This first The second spring unit 5 is indicated by A, similar to the first spring unit 1. A longitudinal central region is formed by the first coil spring 3 and is indicated by B. a second coil spring whose both end portions are softer than the first coil spring 3; 4. At the periphery of the upper and lower surfaces of each spring unit 1 and 5. The frame lines 7 are connected to each other.

[0015] The lower surface of the first spring unit 1 is covered with a first material such as sisal or felt. A first elastic sheet 9 made of urethane foam or the like is bonded via a protective sheet 8. There is. Further, the upper surface of the second spring unit 5 is covered with a second protective sheet 11. A second elastic sheet 12 is bonded thereto.

[0016] The polymer consisting of the first spring unit 1 and the second spring unit 5 is It is integrally covered with an exterior body 13. That is, the exterior body 13 is A first mirror covering the first elastic sheet 9 which is the lower surface side of the spring unit 1. It has 14 earths. The first and second sprues are attached to the periphery of the first mirror area 14. The lower end of the gusset 15 that covers the outer peripheral surfaces of the It is sutured by threads 16.

[0017] The second elastic sheet 12 on the upper side of the second spring unit 5 is It is covered with a second mirror base 17. The periphery of this second mirror area 17 is the same as above. A second tape edge 18 is sewn to the upper end of the crease 15.

[0018] One end of the flange cloth 19 is connected to the inner surface of the periphery of each mirror base 14, 17. tied together. The other end of each flange cloth 19 is connected to each spring unit 1, The first and second elastic sheets 9 and 12 joined to the elastic sheet 5 are wrapped around each other. A clip 2 is attached to a second coil spring 4 located at the periphery of the connected by 1. This prevents the exterior body 13 from shifting. ing.

[0019] The mattress device having the above configuration includes a first spring unit 1 and a second spring unit. Since it is a double cushion type in which the gating unit 5 is polymerized, the upper surface of the The amount of elastic deformation due to the user's load when the user is lying down is compared to the single type. It's all big. Therefore, it is possible to give the user a feeling of soft cushioning. Wear. In other words, cushioning performance can be improved.

[0020] The first spring unit 1 and the second spring unit 5 are shown in FIG. A second coil coil whose longitudinal center portion indicated by A forms both end portions also indicated by B. The first coil has a smaller amount of elastic deformation with respect to the load than the puller 4, that is, it is harder. It is formed by a spring 3.

[0021] The center portion A in the longitudinal direction of each of the spring units 1 and 5 is the heaviest part of the user's body. It supports the buttocks, which is the weakest part of the body. However, the central part A is compared to the other part B. Since it is hard, it does not undergo large elastic deformation under heavy loads. In other words, use Supports the buttocks, which are the heaviest part of a person's body, without causing significant local depression. Ru. Therefore, the user can maintain a sleeping position with his or her back straight, which is a good way to sleep. You can sleep with good comfort.

[0022] Moreover, the center portions A of both the first and second spring units 1 and 5 are hardened. Since the coil spring 3 is formed by the first coil spring 3, the first coil is attached to only one side. Compared to the case where spring 3 is used, the central part A can be made sufficiently hard. It is possible to support the user in a good sleeping position with the back stretched.
