  The pillow according to claim 10 is the pillow according to any one of claims 1 to 8, wherein the molding portion has one hole for inserting a heat conducting rod. To do.

  According to the pillow of the present invention, the far-infrared radiation radiated from the carbon powder of the molding part promotes blood circulation to obtain a health promotion effect, and the heat of the head includes the carbon powder having good thermal conductivity. Since it diffuses throughout the molded part, it is possible to improve sleep and promote sleep. Moreover, the far infrared rays can be increased by applying heat, blood circulation in the lower back and the like can be further promoted, and the health promotion effect can be further increased.

  The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a top view of a pillow 1 according to a preferred embodiment of the present invention. FIG. 2 is a cross-sectional view of the center of the pillow 1 cut in the left-right direction. FIG. 3 is a cross-sectional view of the center of the pillow 1 cut in the front-rear direction. In FIG. 3, the left side is the front end side. The same applies to FIGS. 5, 7, 8, and 9, which will be described later.

  The pillow 1 includes a rigid molded portion 10 that is molded by containing carbon powder. The molding part 10 has a mounting recess 10a in which the head is placed near the center on the front side, and has substantially flat mounting adjacent parts 10b and 10b on both sides thereof, and has a substantially flat plate shape. Specifically, the molded part 10 has, for example, a substantially square plate shape with a length in the front-rear direction of about 20 cm, a length in the left-right direction of about 30 cm, and a height of about 4 cm. The mounting recess 10a has an arc shape with a relatively small curvature as shown in FIG. 2 in the left-right direction, and its width is about 12 cm, for example. In the front-rear direction, the height gradually increases from the front end side and gradually decreases from the middle as shown in FIG. For example, the height of the front end side and the rear end side is about 2 cm and about 1 cm, respectively, and is about 3.5 cm, which is the highest at a position of about 5 cm from the front end side. Further, the vicinity of the center of the front end where the mounting recess 10a is provided is curved toward the rear end side along the shoulder line.

  The carbon powder contained in the molding part 10 may be a charcoal such as charcoal or bamboo charcoal, but is preferably graphite. Since graphite has extremely high thermal conductivity and electrical conductivity, it is highly effective in removing heat from the head, which will be described later, and removing static electricity in the body. Note that charcoal such as charcoal or bamboo charcoal may have low thermal conductivity or conductivity depending on the raw materials and manufacturing method. Accordingly, when a carbide such as charcoal or bamboo charcoal is used, it is desirable to graphitize at a higher processing temperature.

  Furthermore, porous graphite can also be used. Porous graphite has voids formed by solidifying graphite into a fibrous form or an aggregate of particles. The porous graphite molding portion 10 has rough voids or grooves on the surface and inside. Therefore, it is possible to exert a deodorizing effect by adsorption. Moreover, electromagnetic waves harmful to the human body can be absorbed by the rough voids and grooves.

  In the case where the carbon powder is made of graphite, the molding unit 10 mixes, for example, about 3 to 5% by weight of a phenolic resin as graphite as a binder, and pressure is applied to the mixture by a molding machine to form a predetermined lump (for example, a square). It is obtained by molding and then leaving it in an oxygen-free state in a temperature environment of about 2000 ° C. for about a week and then processing it into the desired shape of the molded part 10. The phenol component volatilizes at about 1200 ° C. or higher, and almost 100% of the molded part 10 is formed from carbon powder, so that excellent conductivity can be obtained.

  The molding part 10 coats the surface or attaches a protective layer to the surface for protection such as prevention of defects. As the coating agent for coating, for example, an acrylic water-based resin is used so as to soak into the molding part 10. If it carries out like this, it can protect that the electroconductivity of the surface of the shaping | molding part 10 is hold | maintained. Also, if there is a possibility of using it in places where it is exposed to moisture such as in the bathroom, a water resistant coating is applied. It is desirable that the coating agent further contains a silver component so as to have antibacterial properties. Having antibacterial properties is beneficial because germs on the head can be reduced while sleeping. Moreover, since Legionella bacteria etc. are easy to generate | occur | produce in a bathroom etc., when using it in a bathroom, it is especially useful. In addition, it is desirable that the coating is applied substantially to protect the entire molded part 10.

  Moreover, when the molding part 10 is porous graphite, it is desirable to contain a phthalocyanine. Phthalocyanine exhibits a deodorizing action by catalyzing the oxidation reaction of odor components. Since the molding part 10 contains phthalocyanine, the odorous component adsorbed in the gap can be changed to another substance, so that the deodorizing action can be prevented and the deodorizing action can also be exhibited. This phthalocyanine reacts well even at room temperature and has a long life because it performs a cycle reaction. In addition, phthalocyanine exists, for example as compounds, such as metal phthalocyanine polycarboxylic acid (specifically tetracarboxylic-acid cobalt phthalocyanine, tetracarboxylic-acid iron phthalocyanine, octacarboxylic-acid cobalt phthalocyanine, or octacarboxylic-acid iron phthalocyanine etc.). Moreover, the compound of phthalocyanine can be included in the molding part 10 by dissolving or dispersing in a solution and impregnating.

  Moreover, the molding part 10 may adhere the gold | metal | money layer as a protective layer on the surface, for example, you may adhere a gold foil to the molding part 10 with lacquer. The gold layer has thermal conductivity, conductivity, and antibacterial properties, and can further improve the appearance of the pillow 1. The surface of the gold layer may be coated to prevent wear.

  Next, the usage method and effect | action of the pillow 1 are demonstrated. When using the pillow 1, the head is placed on the mounting recess 10a near the center. Then, the heat of the head is diffused throughout the molded part 10 having good thermal conductivity and escapes to the futon. Thus, by naturally taking the heat of the head, it is possible to improve sleep and promote sleep. Moreover, if the heat of the head is taken, an effect can be expected for the cooling property.

  The static electricity accumulated in the human body escapes from the head through the molding unit 10 to the futon. Therefore, by removing static electricity that adversely affects the human body such as fatigue accumulation, it is possible to obtain effects such as recovery from fatigue, prevention of hair deterioration and rough skin.

  In addition, as described in the description of the background art, the far-infrared radiation emitted from the carbon powder promotes blood circulation, thereby obtaining a health promotion effect. The pillow 1 is substantially composed of a molded part 10, and most of the pillow 1 is carbon powder, so that the amount of far infrared rays is large. Moreover, although the reason is not yet clear, it has been confirmed by the present inventor that carbon powder has an effect of increasing brain α-waves, which can also be expected to have an effect of sleep and health promotion.

  Moreover, since the pillow 1 substantially consists of the molding part 10, and most of it is carbon powder, there is almost no elasticity and it is hard. Therefore, the portion in contact with the head is not deformed and sinks while sleeping, and the position of the head can be stably secured. On the other hand, because of its hardness, there is a concern that it is not comfortable to sleep. However, according to the experiment of the present inventor, by optimizing the size, depth, and shape of the mounting recess in the vicinity of the center of the molding part 10, sufficient sleeping comfort can be ensured even if it is turned sideways. . Moreover, there is no dripping due to use, and durability is high. In addition, it is hygienic because mites, lice, germs, etc. are hardly generated.

  Next, a pillow 2 according to another preferred embodiment of the present invention will be described. This pillow 2 has been devised as being usable for promoting blood circulation in the lower back. FIG. 4 is a top view of the pillow 2 and FIG. 5 is a right surface view. FIG. 6 is a cross-sectional view of the center of the pillow 2 cut in the left-right direction. FIG. 7 is a cross-sectional view of the center of the pillow 2 cut in the front-rear direction.

The pillow 2 includes a rigid molding portion 20 that is molded to contain carbon, and two conductor portions 21a and 21b that serve as electrodes. The molding part 20 has a mounting recess 20a that can be brought into contact with the waist and the head near the center of the front side, and has substantially flat mounting adjacent parts 20b and 20b on both sides thereof, and has a substantially flat plate shape. ing. Specifically, the molded part 20 has substantially the same shape as the molded part 10 slightly larger, for example, the length in the front-rear direction is about 20 cm, the length in the left-right direction is about 40 cm, and the height is about It has a substantially square plate shape of 4 cm. The mounting recess 20a also has an arc shape with a relatively small curvature as shown in FIG. 6 in the left-right direction, and its width is, for example, about 22 cm. In the front-rear direction, as shown in FIG. 7, it gradually increases from the front end side and gradually decreases from the middle. For example, the heights of the front end side and the rear end side are about 2 cm and about 1 cm, respectively, and the height is about 3.5 cm, which is the highest at a position of about 5 cm from the front end side. Further, the vicinity of the center of the front end where the mounting recess 20a is provided is curved toward the rear end side along the waist or shoulder line. Incidentally, in some cases to simplify the shape of the molded portion 10 in terms of cost, particularly increasing the size (e.g., about 50 cm ^□ or higher) it is often curved Then loading recess 20a and the front end near the center of is omitted .

  Moreover, the insertion port 22 which can insert a power supply connector is provided in the right side surface of the shaping | molding part 20, and two power supply pins which can be inserted and connected to the connection terminal part of a power supply connector are embed | buried. One side of the two conductor portions 21a and 21b is embedded in the molding portion 20 so that a part of the molding portion 20 is interposed therebetween, and the other side is exposed as the above-described two power pins. The conductor portions 21a and 21b are made of, for example, a copper alloy, and the exposed portion of the power pin may be made of a material different from other portions.

  Other structures and materials of the pillow 2 are the same as those of the pillow 1.

  Next, the usage method and effect | action of the pillow 2 are demonstrated. When the pillow 2 is used to promote blood circulation in the lumbar region, the power connector is fitted into the insertion port 22, and the power connector is energized so that an AC or DC voltage is applied between the two conductor portions 21a and 21b. To. This voltage is obtained by converting the voltage of the commercial power supply (AC 100V) into, for example, DC 24V. If it does so, an electric current will flow through a part of shaping | molding part 20 interposed between the two conductor parts 21a and 21b, and it will generate | occur | produce with the resistance component which it has. The heat is conducted in a short time to the entire molded part 20 having good thermal conductivity.

  And the center vicinity of the pillow 2 is made to contact | abut to a waist | hip | lumbar part. When the temperature of the carbon molding part 20 rises, the far infrared rays radiated from the carbon powder increase. Therefore, the far-infrared radiation effectively radiated increases the blood circulation in the lumbar region, thereby increasing the health promotion effect. A plurality of pillows 2 may be used in contact with each other.

  The pillow 2 has been devised as a pillow (waist pillow) that can also be used to promote blood circulation in the lumbar region, but can be used by contacting various parts of the lying human body such as elbows and knees. For example, when the foot 2 is brought into contact with the pillow 2 in the form of a foot pillow that makes it easy to make the pillow 2 contact the sole, the effects of foot bathing such as improvement of sleep, relaxation, and health promotion can be obtained. In particular, since no water is used, it is suitable for a patient to use in bed.

  Of course, the pillow 2 can be used as a pillow for the head similarly to the pillow 1 without fitting the power connector into the insertion slot 22. In this case, the pillow 2 can obtain the same effect as the pillow 1. Moreover, you may raise the temperature of the shaping | molding part 20 by providing heat from the back side, without providing the conductor parts 21a and 21b and the insertion port 22. FIG. For example, a nichrome wire, an electric fire, a hood that generates heat due to a chemical change, or the like can be used as the heating means and can be brought into contact with the back side.

  Next, a pillow 3 according to still another preferred embodiment of the present invention will be described. This pillow 3 is a modification of the pillow 2 described above. FIG. 8 is a right surface view of the pillow 3, and FIG. 9 is a cross-sectional view of the center of the pillow 3 cut in the front-rear direction. The pillow 3 has a single hole 31 for inserting a heat conduction rod into a rigid molded part 30 that is molded containing carbon powder. A heat conduction rod (not shown) is made of a material having excellent heat conductivity, and heat generated by an external device is conducted from the heat conduction rod to the entire molding unit 30 in a short time. Thus, the pillow 3 can be used in the same manner as the pillow 2. The pillow 3 needs to generate heat in an external device, but the molding part is easier to process than the pillow 2.

  Although the pillow according to the preferred embodiment of the present invention has been described above, the present invention is not limited to the one described in the embodiment, and various design changes can be made within the scope of the matters described in the claims. Is possible. For example, in order to further improve the sleeping comfort, the dimensions and shapes of the molding parts 10, 20, and 30 described in the embodiments can be changed as appropriate. Moreover, it is also possible to color the molding parts 10, 20, and 30 and to draw a pattern for aesthetics.
