Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mattress device that can disperse body pressure.
[0003]
[Prior art]
In general, a mattress device has a spring unit, and an elastic layer made of a foamed elastic material such as foamed polyurethane is polymerized on at least the upper and lower surfaces of the spring unit, and this polymer is covered with an exterior. Has been.
[0004]
However, according to the mattress device having such a configuration, when the user lies on the mattress device, a heavy part of the body, for example, the buttocks or the like, sinks greatly by elastically deforming the elastic layer and the spring unit. A large repulsive force will be generated.
[0005]
As a result, the buttocks are pressed by the repulsive force of the elastic layer and the spring unit, so it is necessary to sleep for a long time, for example, the elderly and sick people cannot turn over freely. In the case of such a user, there was a case where humiliation easily occurs in the buttocks.
[0006]
Therefore, it has been studied to use a low-repulsive elastic material such as a low-repulsive urethane foam that hardly generates a repulsive force against a load for the elastic layer. The low rebound resilience material has an advantage that rebound resilience is very small and has excellent absorption performance against impact.
[0007]
For this reason, when the user's load is applied, the low-rebound elastic material gently sinks according to the unevenness of the body to support the body, so that the repulsive force is difficult to concentrate on the heavy part of the user's body and the body pressure is dispersed There is an effect to make. As a result, since the stress applied to the spring unit is also dispersed, it may be difficult for the body to develop humiliation even when sleeping for a long time.
[0008]
[Problems to be solved by the invention]
By the way, the low resilience elastic material has temperature dependency in which hardness varies depending on temperature. In other words, since the low resilience elastic material becomes hard at low temperatures, the low rebound resilience material may give a hard feel to the user until the temperature rises due to body temperature in winter when the room temperature decreases. There were times when it could not be used in the state.
[0009]
The present invention provides a mattress device capable of preventing the low-repulsion elastic material from becoming hard when the temperature is low, such as in winter, by providing a heating unit that can heat the low-repulsion elastic material to a predetermined temperature. It is to provide.
[0011]

[0014]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
[0015]
The mattress device of the present invention shown in FIG. 1 includes a spring unit 1 as a first cushion body. This spring unit 1 has a large number of coil springs 2 arranged in a matrix, the upper end surface and the lower end surface of adjacent coil springs 2 are connected by helical wires 3, and a frame line 4 is provided at the peripheral portions of the upper and lower surfaces. One is connected by a clip (not shown).
[0016]
A plate-like upper protective layer 5 and a lower protective layer 6 are joined to the upper and lower surfaces of the spring unit 1, respectively. Each of the protective layers 5 and 6 is made of a material such as compressed cotton or relatively hard urethane foam.
[0017]
As shown in FIG. 3, a bottom member 7 such as a urethane sheet is laid on the upper protective layer 5, and a frame-like elastic material 8 formed of a material such as urethane foam is provided on the bottom member 7 at the lower end surface. Are attached and fixed to the peripheral portion of the bottom member 7.
[0018]
A low resilience elastic material 10 as a second cushion body is provided inside the frame-shaped elastic material 8. The low resilience elastic material 10 is formed by joining a lower member 11 and an upper member 12 having a thickness of about half the height of the frame-shaped elastic material 8.
[0019]
Between the lower member 11 and the upper member 12, a pair of heat-resistant sheets 13 made of, for example, a heat-resistant nonwoven fabric is provided over almost the entire surface. Between the heat resistant sheets 13, a one-line heating element 14 as a heating means bent in a meandering manner is provided over almost the entire surface of the low resilience elastic material 10.
[0020]
One end of a belt-like connecting member 15 such as a velvet fastener is engaged and held on the periphery of the upper surface of the heat-resistant sheet 12 positioned on the upper side. The other end of the connecting member 15 is inserted between the bottom member 7 and the frame-like elastic material 12 and is integrally bonded and fixed thereto. As a result, the heating element 13 is held immovably on the lower member 11 of the low resilience elastic material 10 via the heat resistant sheet 12.
[0021]
The heating element 13 is supplied with power via a temperature setting device 16. The temperature setter 16 can set the temperature of the heating element 13. As a result, the low rebound elastic material 10 can be heated and maintained at a predetermined temperature from the lower member 11 and the upper member 12.
[0022]
The laminated body of the spring unit 1 and the low-rebound elastic material 10 is covered with an exterior ground 21. This exterior ground 21 includes a lower mirror base 22 that covers the lower protective layer 6, an upper mirror base 23 that covers the upper surfaces of the frame-like elastic material 8 and the low-elasticity elastic material 10, the spring unit 1, and the frame-like elasticity. It comprises a town 24 covering the outer peripheral surface of the material 8, and the upper and lower ends of the town 24 are integrally stitched to the peripheral parts of the lower mirror 22 and the upper mirror 23 with a tape 25.
[0023]
According to the mattress device having such a configuration, when a user lies on the upper surface, the load of the user is supported by the low rebound elastic material 10 provided in the frame-shaped elastic material 8. In other words, when a user's load is applied to the low-repulsion elastic material 10, the low-repulsion elastic material 10 gently sinks according to the unevenness of the body to support the body, so that the repulsive force is concentrated on a heavy part of the user's body. The load applied to the spring unit 1 is also distributed accordingly.
[0024]
Therefore, even if the user is an elderly person or a sick person and cannot turn over freely, the heavy part of the user's body can be kept from being pressed and humiliation can be prevented. it can.
[0025]
A heating element 14 is provided between the lower member 11 and the upper member 12 of the low resilience elastic material 10. The heating element 14 can be maintained at a predetermined temperature by the temperature setting device 16. That is, when there is a possibility that the room temperature is lowered and the low rebound elastic material 10 is hardened, such as in winter, the temperature of the low rebound elastic material 10 is set to be hard by the temperature setting device 16. It is set to be maintained at a predetermined temperature that does not become necessary.
[0026]
As a result, the low-rebound resilience material 10 can be prevented from becoming hard even when the room temperature decreases, such as in winter, so that the user can use the mattress device without impairing the soft feel. Can do.
[0027]
Further, since the low-rebound elastic material 10 is divided into the lower member 11 and the upper member 12 and the heating element 14 is provided between these members 11 and 12, the heating element 14 causes the lower member 11 and the upper member 12 to be separated from each other. Can be heated in the same manner throughout. That is, the low-rebound resilience material 10 can be heated uniformly over the thickness direction.
[0028]
The low resilience elastic material 10 is not easily maintained in its outer shape, but can be maintained in the shape of the frame-shaped elastic material 8 because it is accommodated in the frame-shaped elastic material 8. That is, the outer shape of the mattress device can be favorably maintained by the frame-shaped member 8.
[0029]
The present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the low-rebound elastic material is superposed on the upper surface of the spring unit as the first cushion body. May be a cushion body formed of urethane foam or the like instead of the spring unit, and the configuration of the first cushion body is not limited.
[0030]
【Effect of the invention】
As described above, according to the present invention, the low rebound elastic material is provided on the surface supporting the user of the mattress device, and the heating means for heating the low repulsion elastic material is provided.
