Description

[Detailed description of the invention] [Industrial application field] This invention has a three-layered futon that has acupressure effects, chiropractic effects, etc., and is equipped with a planar heating element that emits far infrared rays. This relates to a futon that is equipped with heating effects, etc.

[Conventional technology]

Far infrared rays in the invisible region with particularly long wavelengths have a high degree of heat absorption by the human body, promoting blood circulation,
It has excellent thermal therapeutic effects such as relieving various types of muscle fatigue. On the other hand, the spine, starting from the cervical vertebrae and ending at the coccyx, is the basic part that protects and supports the important central nervous system, and there are many important points (points) on the back of the human body, mainly in the area around the spine. scattered,
Irradiating far-infrared rays to these local areas is an effective means for regulating autonomic nerves, relieving various types of pain, and eliminating accumulated fatigue. Currently, there are no devices equipped with a heating element that emits far infrared rays.

As shown in Figure 6, futons that incorporate heating elements that emit far-infrared rays, which are seen in the past, have carbon or other electrical conductors placed above the flat plate-like slightly rigid support B from the feet to the chest. A planar heating element A having a large area and a substantially rectangular shape, which is made by covering a resistor with an insulating vinyl sheet or the like.
A thin cushion body C made of a flat sheet of synthetic fiber cotton, foamed urethane, etc. is placed on the planar heating element A, and the support A, the planar heating element B,
The cushion bodies C are laminated and covered with an exterior fabric D.

[The problem that the idea aims to solve]

The above-mentioned conventional futon incorporating a planar heating element that emits far-infrared rays has no breathability because the large-area heating element is covered with a vinyl sheet, etc., and the human body that comes into contact with the futon while sleeping Moisture and sweat generated from these areas are difficult to escape, often causing discomfort to the user.As the futon is used, the elasticity of the cushion body decreases, making it even more difficult for moisture and sweat to escape. In some cases, moisture remained and mold and odor developed. In addition, the futon had a thin overall structure, making it feel hard to sleep on, and the only therapeutic effect that could be obtained while sleeping was a thermal effect. In addition, it consisted of a large heating element that covered everything from the feet to the chest, and required a large amount of electricity to generate heat.

In addition, although it is true that the above-mentioned conventional futon incorporating a planar heating element that emits far infrared rays can obtain the necessary thermal treatment effect, including the above-mentioned acupuncture stimulation effect, Because it is placed over a large area on the futon, it exerts the effect of warming the user's entire body like an electric blanket or electric bed sheet, and as a result, at least the majority of people find the whole body heating uncomfortable. It was extremely difficult to use during the summer months. Furthermore, even if the product is used in the winter, those who only intend to treat the acupuncture points will not be able to experience the sensation of local stimulation (i.e., the actual sensation of treatment).

This invention utilizes the shape of the components of the three-layer futon, which has acupressure treatment effects and chiropractic treatment effects,
Provides local therapy, thermal effect, and heating effect to the human body using far infrared rays with low power consumption without impairing breathability, making it comfortable to sleep, allowing you to gain health while lying down, and having medical therapeutic effects. The purpose is to provide futons that can be obtained.

[Means to solve the problem]

The above-mentioned problem lies in the fact that the bottom layer is made of a flat plate-shaped synthetic resin foam material that has an elastic restoring force, and the synthetic resin foam material is formed on the top surface with continuous wavy portions that are approximately parallel to the width direction of the futon. An intermediate layer that is resistant to compressive loads and an upper layer that is made of a synthetic resin foam material and has an elastic restoring force and has many mountain-shaped convex portions and many reverse mountain-shaped concave portions formed on the upper surface are laminated. a three-layer structure with a longitudinal direction substantially parallel to the width direction of the futon at a position corresponding to the foot of a supine human body on the upper surface of the three-layer structure and corresponding to the concave portion of the wavy portion of the middle layer; A plurality of substantially rectangular sheet heating elements emitting far infrared rays are disposed at positions, and a plurality of sheet heating elements are disposed on the upper surface of the three-layer structure at positions approximately corresponding to the positions of the acupuncture points dotted on the back surface of the supine human body. The problem is solved by a far-infrared ray-emitting three-layer structure futon, characterized in that a sheet heating element that emits far-infrared rays is disposed, and the three-layer structure and the sheet heating element are covered with an exterior fabric. be done.

〔Example〕

Hereinafter, the configuration of the present invention will be explained based on the drawings.

FIG. 1 is a partially cutaway perspective view showing an embodiment of a far-infrared radiation three-layer futon 1 according to the present invention. The three-layer structure 2 includes a bottom layer 3 made of a flat plate-shaped synthetic resin foam material such as foamed polyurethane, which has an elastic restoring force and has the purpose of absorbing external vibrations that disturb sleep, and a futon width. An intermediate layer 4 made of a synthetic resin foam material such as foamed polyethylene and having a wavy portion formed on the upper surface in which convex portions 4a and concave portions 4b are repeated and continuous substantially parallel to the direction, and has resistance to compressive load loading, and an upper surface. It is a three-layer structure in which an upper layer 5 having an elastic restoring force made of a synthetic resin foam material such as foamed polyurethane is laminated with a large number of mountain-shaped convex portions 5a and a large number of reverse mountain-shaped concave portions 5b. . The middle layer 4 is a slightly rigid wavy body that firmly supports the weight of the human body M lying on its back.
It provides a correct sleeping posture without causing heavy parts such as the back to sink in excessively.
It has the effect of correcting the distortion of the spine caused by unreasonable posture during the day (manipulative effect) and alleviating or curing disorders such as lower back pain. Further, the upper layer 5 softens the weight support by the intermediate layer 4 (particularly the convex portions 4a), and provides an effect (acupressure effect) in which the many convex portions 5a of the upper layer 5 press against the surface of the human skin.
Reference numeral 6 is a net body which prevents deterioration of the weight support strength of the three-layer structure 2 and contributes to long-term stable use.

On the upper surface of the three-layer structure 2 described above, there are planar heating elements 7 that emit far-infrared rays at positions approximately corresponding to the positions of the pressure points scattered on the back surface of the human body M lying on its back.
For example, it is arranged as a small piece having a substantially rectangular shape or a substantially circular shape.
In addition, as shown in FIG. 1, on the top surface of the three-layer structure 2 at the foot of the futon, there are a plurality of substantially rectangular planar surfaces that emit far infrared rays, the longitudinal direction of which is approximately parallel to the width direction of the futon 1. By arranging a plurality of heating elements 8 at positions corresponding to the upper part of the recess 4b of the intermediate layer 4, it is possible to exert a heating effect on the foot area and further a heating effect on the foot area in winter. .

The planar heating element 7 consisting of a small piece and the planar heating element 8 having a substantially rectangular shape are usually obtained from an electrical resistor made of fine carbon particles, or a foil-shaped copper alloy electrical resistor coated with a far-infrared radiation coating. The heat generating element itself has a self-temperature regulation function, that is, as the temperature of the heat generating element rises to a certain level, the electrical resistance value increases and the current value decreases. However, if the heating element is a planar heating element that has the property of being maintained at a constant temperature, for example, an organic heating element made of fine carbon particles such as graphite and a high molecular weight polymer, as shown in Fig. 4, according to an actual measurement example. The heating element is automatically maintained at a constant temperature of around 50°C, and the electricity consumption is less than 50% compared to heating elements that do not have self-temperature adjustment characteristics.
Control components such as a temperature regulator or abnormal temperature rise prevention switch are not required, and energy is saved.

Furthermore, the far infrared rays emitted by the planar heating element 7 are similar to those of the planar heating element 8, but it is efficient to emit more far infrared rays toward the supine side, that is, the upper surface of the human body, as shown in FIG. By attaching a far-infrared reflector 13 such as aluminum foil or an aluminum vapor-deposited resin sheet to the lower surface of the planar heating element 7 to reflect far-infrared rays, the far-infrared rays radiated downward can be radiated upward. The planar heating element 7 and the planar heating element 8
The power consumption can be further reduced in operation.

In addition, an ion electric bed band 9 made of a flexible woven fabric coated with a carbon-containing good conductor may be attached to the planar heating element 8 at, for example, the feet, and a high-voltage negative charge can be transferred to the ion electric bed. When applied to the band 9, it prevents acidification of the human body and allows negative potential therapy to be performed during sleep, which has a therapeutic effect on back pain, stiff shoulders, insomnia, etc.

The above planar heating element 7, planar heating element 8, and ion electric bed band 9 include a control device 1 including a power supply circuit, a timer circuit, a negative potential generation circuit, a changeover switch, etc.
Control power is supplied from 4 through a connection cord 15, a connection connector 16, and a wiring cable 17. If the control device 14 is provided with a switch that allows only the planar heating element 7 to operate, only local (point) therapy using far infrared rays can be performed in summer or the like.

The planar heating element 7 may be placed on the upper layer of the three-layer structure 2 by means of adhesion such as adhesive, or by means of locking (not shown) such as a string-like body or a stopper, but as shown in FIG. The three-layer structure 2 is wrapped in a bag-shaped envelope 9 made of a flexible and breathable material, such as woven fabric or non-woven fabric, and placed at a position approximately corresponding to the position of the acupuncture points on the back of the human body. The planar heating element 7 is attached to the package 10 by means such as sticking or sewing, or by forming a bag portion corresponding to the size of the planar heating element 7 in the package 10 at the location where the planar heating element 7 is disposed. The planar heating element 7 may be disposed by inserting it into the bag.

Similarly, the planar heating element 8 and the electric floor band 9 may be laid on the upper layer of the three-layer structure 2 by means of adhesion such as adhesive, or by means of locking with a string-like body or a stopper (not shown). However, as shown in FIG. 3, the three-layer structure 2 is wrapped in a bag-shaped envelope 10 made of a flexible and breathable material, such as woven fabric or non-woven fabric, and the middle layer 4 is The planar heating element 8 is pasted or sewn onto the envelope 10 at a position corresponding to the upper part of the recess 4b, or a bag corresponding to the size of the planar heating element 8 is placed at the placement position of the planar heating element 8. Alternatively, a section may be formed in the envelope 10 and the planar heating element 8 may be inserted into the bag section.

In FIGS. 1, 2, and 3, 11 is the exterior side material, which includes the three-layer structure 2, the sheet heating element 7, the sheet heating element 8, the ion electric bed band 9, the envelope 10, etc. It has a beautiful covering.

The futon 1 of the present invention may be in one piece when used on a bed, etc., but when used in a Japanese-style room, it can be easily stored by dividing the futon 1 into approximately three parts in the longitudinal direction so that it can be folded into three parts.・It becomes convenient for transportation.

[Functions and effects of the invention]

As explained above, when the human body M lies supine on the futon 1 of the present invention, the connector 16 is connected, and the control device 14 is turned on and the desired operation is started,
The planar heating element 7 is energized and far infrared rays are irradiated to approximate pressure point positions on the back of the human body M to perform local (acupoint) therapy, and the planar heating element 8 at the feet has a thermal effect and a heating effect. Furthermore, the unique structure of the three-layer structure 2 provides an acupressure effect, a chiropractic effect, etc., and a negative potential is added to the ion bed band 9 to improve the human body M.
It is charged with a negative potential and can have a negative potential therapeutic effect.

Since the sheet heating element 7 in the present invention has a small area, the area where the supine human body M and the sheet heating element 7 come into contact is small, and the presence of the sheet heating element 7 prevents moisture from remaining in the futon. It is impossible for the amount of sweat etc. to increase, and Fig. 6 shows that the amount of sweat etc. in the conventional futon described above is not increased.
This prevents new problems such as sweat being difficult to remove, moisture remaining, or mold and odor. On the other hand, since the substantially rectangular sheet heating element 8 is disposed on the upper surface of the three-layer structure 2 and corresponding to the recess 4b of the intermediate layer 4, the sheet heating element 8 is caused by the supine body M. Since it is not subjected to body pressure, no load is applied to the planar heating element 8 itself, so it will not be damaged even when used continuously for a long period of time, and has a long life.
Although the skin surface of the human body M and the planar heating element 8 cannot be in close contact, there is an appropriate space, that is, the recessed space of the recessed part 5b of the upper layer, the recessed space of the intermediate layer recessed part 4, or the upper layer as shown in FIG. 5 are laminated along the surface shape of the intermediate layer 4, there is a lot of space around the planar heating element 8, and the air permeability is good. It does not have the disadvantages of the futon in which moisture and sweat are difficult to remove, moisture remains, or mold and odor are generated.

In addition, in the present invention, since the sheet heating element 7 or 8 is a heating element with a small area, it does not require large electric power as in the conventional example shown in FIG. In a planar heating element having functional characteristics, further power saving is possible, fires and low-temperature burns are less likely to occur, and temperature control parts can be omitted. Further, as explained in FIG. 5, by attaching far-infrared reflectors to the lower surfaces of the planar heating elements 7 and 8, further power saving can be achieved.

Moreover, if the sheet heating element 7 and the sheet heating element 8 are arranged in the envelope 10, the three-layer structure 2, the sheet heating element 7, and the sheet heating element 8 are separated, and even when manufacturing the futon. In addition, assembly, replacement, etc. can be easily performed during future maintenance and inspection.

In addition, since the present invention is composed of the three-layer structure 2 having a unique structure, the upper layer 5 provides an acupressure effect, body pressure is dispersed, and good cushioning properties are obtained. The futon 1 of this invention has a layer that supports your body weight with appropriate firmness without sinking in your buttocks, back, etc., allowing you to maintain a correct sleeping posture, and the bottom layer prevents transmission of vibrations from the outside world and provides appropriate elasticity. Moreover, the sleeping comfort does not feel hard as in the conventional example shown in FIG.

As described above, the far-infrared radiation three-layer futon according to the present invention emits far-infrared rays at predetermined positions approximately corresponding to the positions of the acupuncture points scattered on the back of the human body with low power consumption without impairing breathability. Since a radiating heating element is installed, far infrared rays are concentrated only on the pressure points, which adjusts the autonomic nerves, relieves various pains, eliminates accumulated fatigue, etc., even in the summer when the ambient temperature is high. It can be used without discomfort, and in addition, with a small amount of electricity, it can promote blood circulation in the feet area where fatigue is most likely to occur, relieve muscle fatigue, etc., and has a warming effect in winter, as well as a heating effect in the winter. It is possible to add negative potential therapy, which has a therapeutic effect on lower back pain, stiff shoulders, insomnia, etc., and also provides acupressure effects, chiropractic effects, etc., and these effects can be obtained individually or as a combination of two or more effects. Depending on the effect, it may be possible to more effectively remove the fatigue of the day during sleep, heal diseased areas, and create a healthy body.
