Description

[Technical field]

[0001] Satisfy both the needs of extreme heat and power saving, or the needs of extreme cold and power saving. [Background technology]

[0002] Abnormal weather is occurring frequently around the world, and in summer, temperatures exceeding 40 degrees are seen in many places in Japan. In such extreme heat, body temperature rises, and there is a risk of heat stroke. In winter, it can also be extremely cold. On the other hand, electricity shortages mean that electricity conservation is necessary. These two contradict each other. Below we will explain in detail how to deal with extreme heat, but the same idea applies to dealing with extreme cold. Conventionally, indoor cooling is generally done with air conditioners, but this consumes a large amount of energy and is not efficient. When going outside, people use parasols, cooling towels, handheld fans, neck fans, neck coolers, etc., but these are not effective in extreme heat. Therefore, the present inventors have researched efficient spot cooling technology using ultra-small energy-saving air conditioners and small simple cooling and heating devices that can save electricity and cool the body efficiently.

[0003] [Patent Document 1] Patent Publication No. 2017-026231 Summary of the Invention [Problem to be solved by the invention]

[0004] Indoor air conditioners use a lot of electricity. Handheld fans and neck fans simply blow air, so there is a problem that heat cannot escape from the body in abnormally high temperatures. Recently, a cold collar-like ring has been used to cool the neck, but this is not suitable for rapidly cooling the whole body. It has been proven by the US military that cooling the AVA section is the most efficient method. Furthermore, neck coolers have been shown to be ineffective by research at Harvard University. In the first place, as disclosed in Patent Document 1, the inventor of this application invented a micro air conditioner that blows or contacts cool air using a Peltier element. The human body can be cooled efficiently by cooling specific parts of the body, and Patent Document 1 discloses that a power-saving ultra-compact cooling device using a Peltier element is used to cool the back of the hand, forehead, and chest, but to cool more efficiently, it is more efficient to cool (warm) the AVA part in the palm of the body. However, Patent Document 1 does not disclose the structure and how to cool (warm) the AVA part. In order to survive this abnormal weather, the inventor has conducted extensive research into a cooling / heating device that can save power while also taking measures against extreme heat, and that maximizes the cooling and heating effects of the AVA part, and has completed this invention. [Means for solving the problem]

[0005] In the present invention, a cooling or heating device having a cooling / heating section is used to contact the AVA portion of the palm at the part of the device that comes into contact with the palm, such as a chair armrest, a writing implement such as a pen, a cane, an umbrella, a handlebar, or a glove. Effect of the Invention

[0006] The present invention can provide inexpensive and effective cooling or heating while saving electricity. The present invention can easily cool the body by simply installing it on chair armrests, writing implements such as pens, walking sticks, umbrellas, handlebars, gloves, and other implements that come into contact with the palm of the hand. The present invention is a folding chair that utilizes the latest technology to combat heat, and can be used indoors, such as in a living room at home or in an office, or outdoors, such as at campsites or events, to efficiently cool the body. This invention is a two-pronged approach that can simultaneously solve both the problem of extreme heat and the problem of saving electricity. This invention is specialized in pinpoint cooling of the area where the vein and artery anastomose (AVA area), which is inexpensive, saves energy, and has the effect of efficiently lowering body temperature, as proven by experiments at MIT.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] [First embodiment of the present invention] Fig. 1 shows a first embodiment of the present invention, in which a cooling / heating device 3 of the present invention is provided at the end of an armrest 101 of a foldable chair 1 such as a camping chair. Fig. 1(A) is a side view showing a user 2 sitting and using the present invention, and Fig. 1(B) is a front view of the chair with the cooling / heating device 3 of the present invention provided. The cooling / heating tool 3 is a small device with a cold contact or cold air blowing mechanism that can cool or heat the palm, for example, the "Ultra-small Cooling / Heating Device" in the inventor's Patent No. 6352866. This cooling / heating tool 3 supplies electricity to the Peltier element from a battery via a USB connector and cable, and the Peltier element performs cooling and heat generation. A heat dissipation fin is provided on the heat generating side, a heat insulating material is provided to cover this, and fins are also provided on the cooling section. The cooling or heating device 3 is then fixed by adhesion, sewing, or the like to the vicinity of the tips of the left and right armrests 101. The battery 32 is placed in a bag 31 provided on the side of the chair (FIG. 1(B)). A user 2 of the present invention sits on a chair 1 and places the AVA portion 21 of the palm of his / her hand in contact with the upper surface of the cooling / heating device 3, thereby cooling and warming the body more efficiently (FIG. 1(A)).

[0009] There is a reason why cooling and heating devices are placed in contact with the palm of the hand. The inventor teaches at Harvard University, and utilizing the latest research from Harvard University, there is a method for cooling the human body most efficiently. It has been discovered that blood vessels called arteriovenous anastomoses (AVAs) regulate body temperature, and cooling these AVAs can regulate the body's temperature very efficiently. This method has been officially adopted by the U.S. military. This AVA is located in the palm of the hand, so cooling (heating) the palm is theoretically effective in regulating body temperature.

[0010] The power source 32 such as a battery for the cooling / heating device 3 is kept in a bag 31 provided on the side of the chair to prevent it from getting dirty and to make it easy to take in and out, but it may also be placed on the floor or hung from the chair post. The cooling / heating device 3 may not only be provided on the armrests 101 on both sides, but may also be detachably provided on only one side. The end of the armrest 101 where the cooling / heating device is provided means that the cooling / heating device 3 is provided at a position about 0 mm to 100 mm from the extreme end of the armrest 101 so that the cooling / heating device 3 is under the palm 21 placed on the armrest when the user sits on the chair. The method of supplying electricity is not limited to the cable 33 described in this embodiment, but may be electrical transmission, or the battery 32 may be built into the cooling / heating tool. The chair in which the cooling / heating device of the present invention is provided is not limited to a folding chair, but may be a wooden chair that cannot be folded.

[0011] [Second embodiment of the present invention] FIG. 2 shows a second embodiment of the present invention, in which a bag 41 for containing a cooling agent or a heating agent 4 is provided at the end of an armrest 101 of a foldable chair 1 such as a camping chair. The bag 41 is fixed near the tip of the armrest 101 with an adhesive or the like, and a cooling or heating agent 4 is inserted into the bag 41 .

[0012] For outdoor use, the cooling or heating agent is preferably a chemical-filled heat / cold pack that is easily portable. The coolant may be a sheet made of nonwoven fabric and water-containing polymer gel, which removes heat by evaporation, a frozen polymer gel material, or ice. The heating agent is preferably a heat generating agent (such as a disposable hand warmer) made of nonwoven fabric, iron powder, water, vermiculite, activated carbon, etc., which utilizes the heat generated by the oxidation reaction of iron, but a heated object or hot water may also be used.

[0013] The bag 41 fixed to the armrest 101 is preferably a vinyl bag with a zipper, but a drawstring nonwoven bag, cloth bag, etc. may be used, and the material and structure are selected for the purpose of gentle cooling or heating, prevention of falling, and prevention of water leakage.

[0014] [Third embodiment of the present invention] FIG. 3 shows a third embodiment of the present invention in which a heating and cooling mechanism 6 of the present invention is provided on the "Mental Work Factory Chair" (Announcement H02-012564) (trade name: Celebrex) (hereinafter referred to as the chair 5) invented by the present inventor. In addition to the original chair structure (seat 57, armrests 558, and backrest 59), chair 5 is also provided with a foot heating section 52 that heats the soles of the feet, a head cooling section 51 that cools the back of the head, refrigerant piping 53, a compressor and heat exchanger 55, and a hood 59 (Figure 3(A)). In the head cooling section 51, the refrigerant evaporates and absorbs heat to cool the back of the head, and the refrigerant that returns to the compressor 55 is liquefied and sent to the head again. The heat generated when the refrigerant is liquefied is sent to the foot heating section 52 through the heat exchanger 55 to warm the soles of the feet. In the present invention, the heat medium pipe 54 connected to the foot heating section 52 is extended to the armrest of the chair, and a small heat dissipation section 62 is provided in the armrest section 56. The refrigerant pipe 53 connected to the head cooling section is also extended to the armrest 56 of the chair, and a small cooling section 61 is provided (FIG. 3(A)). FIG. 3(B) is a front view, and as shown in the enlarged view, the small heat dissipation portion 62 and the small cold-heat portion 61 are arranged at the inner corner and outer corner of the upper surface of the armrest 56, resulting in structure 6 that allows the user to contact the AVA portion of the palm of the hand for either cooling or heating whenever desired. The size of the small heat dissipation portion 62 or the small cold portion 61 is preferably small enough to fit in the palm of the hand.

[0015] The small heat dissipation part and the small cold part are positioned near the tip of the armrest 56, but they may be positioned within reach of the palm of the hand for easy use, and covers may be provided for the small heat dissipation part and the small cold part to prevent overcooling or overheating.

[0016] According to the third embodiment of the present invention, the AVA area of ​​the palm can be stably cooled or heated for a long period of time by the compressor, heat exchanger 55, and refrigerant, so that the physical condition can be further improved.

[0017] [Fourth embodiment of the present invention] FIG. 4 shows a fourth embodiment of the present invention, in which a cooling / heating device 7 of the present invention is provided with a connecting portion 72 at a cooling portion 71 that can be clamped by a writing tool such as a pen. The cooling / heating device 7 of the present invention has a function of being detachably attached to an implement such as a writing instrument. The joint 72 is provided with, for example, three grippable legs, which are curved legs having elastic strength sufficient to grip the writing implement such as a pen and prevent the cooling part 71 from wobbling. The material of this joint may be rubber, plastic, metal steel, or the like, with rubber or plastic being preferred. The cooling part 71 may have any shape that is easy to hold in the hand. It is preferably a barrel-shaped cylinder with a diameter of 10 to 50 mm and a length of 10 to 70 mm. It is made of a thin plastic, vinyl, or metal tube case and has a structure in which a cooling agent or heating agent can be inserted. The number of legs 72 of the joint does not have to be three, but may be three or more. In order to have the function of attaching the present invention to the top or body of a pen, it is preferable that there are three to six legs.

[0018] According to the fourth embodiment of the present invention, the product of the present invention is provided in the part held in the hand, and by gripping the product of the present invention, the device can be carried around and at the same time the AVA part of the palm can be cooled and warmed, thereby relieving fatigue and improving physical condition.

[0019] [Fifth embodiment of the present invention] FIG. 5 shows a fifth embodiment of the present invention, in which the product of the fourth embodiment of the present invention is attached to the head 81 of a writing implement 8 such as a pen. The material and structure are as described in the fourth embodiment, but the legs 72 of the joint are 10 to 30 mm long and 2 to 5 mm wide so that they can be fitted to a writing implement such as a pen 8. The legs of the joint may be made of a rubber material and have a cap shape that covers the entire circumference of the cooling part. By holding the product 7 of the present invention while holding a writing implement 8 such as a pen, the AVA area is stimulated, thereby improving physical condition.

[0020] [Sixth embodiment of the present invention] FIG. 6 shows a sixth embodiment of the present invention, in which a semi-cylindrical joint portion capable of being clamped is provided in a cooling / heating tool 9 of the present invention and the tool is attached to a pen. The cooling / heating device of the present invention is detachable. As shown in FIG. 6, the body 82 of the writing instrument 8 such as a pen, which comes into contact with the hand, has a semi-cylindrical barrel-shaped cooling / heating part 91 having a length of 10 to 70 mm and a thickness of 3 to 15 mm, and the inside is a hollow case into which a cooling agent or a heating agent can be inserted. Semi-cylindrical cooling / heating part 91 is preferably made of rubber, plastic, or metal with good thermal conductivity, but if it is made of metal, rubber may be attached to the part that comes into contact with the cylindrical writing implement. The semi-cylindrical cooling / heating part 91 is hollowed out like a fish cake along its central axis so that it can be held over the pen, and a cooling or heating agent is inserted into the semi-cylindrical barrel-shaped cooling / heating part 91 so that cooling and heating are transmitted to the palm when the writing implement is held. When the semi-cylindrical cooling / heating part is placed over the writing instrument and the gripping force is weak and the writing instrument comes off, the semi-circular structure is made into a shape that can grip the writing instrument by further covering it. "Covering more" means that the cooling / heating tool 91 of the present invention is made into a semi-cylindrical shape that can grip the writing instrument, for example, from 1:30 to 10:30 when viewed clockwise in cross section.

[0021] This allows the AVA section to be cooled without having to take your hand off the screen while writing with a pen or other writing instrument, allowing for comfortable work.

[0022] [Seventh embodiment of the present invention] FIG. 7 shows a seventh embodiment of the present invention, in which the product 7 of the fourth embodiment is attached to the grip portion of a writing implement 8 such as a pen, approximately perpendicularly. Since the user can continue to hold the cooling part 71 while writing, the cooling effect is further improved. It can also be used as a training tool for how to hold a writing implement such as a pen correctly.

[0023] [Eighth embodiment of the present invention] FIG. 8 shows an eighth embodiment of the present invention, in which the sixth embodiment of the present invention is attached to the handle of an umbrella 10. As shown in FIG. The handle of umbrella 10 has a diameter of about 10 to 20 mm and is bent in an "U" shape, so the size of the semi-cylindrical cooling / heating tool 9 of the present invention is adjusted according to the thickness of the handle and the length of the straight part of umbrella 10. For example, semi-cylindrical cooling / heating part 91 is 60-70 mm long, the inner diameter of the part that grips the inner umbrella is about 10 to 20 mm, and it is hollow with an outer diameter of 30 mm, into which a cooling / heating agent is inserted. This allows the AVA portion of the palm to be cooled or heated comfortably even when holding a parasol 10 or on a rainy day. Furthermore, if the product of the present invention is provided at the bent portion of the handle of the umbrella 10, the user can hold the product of the present invention while carrying the umbrella 10 closed, allowing the user to stay in good physical condition even in extreme heat or cold.

[0024] [Ninth embodiment of the present invention] FIG. 9 shows a ninth embodiment of the present invention, in which the product 9 of the sixth embodiment of the present invention is attached to the handle of a walking stick 11. The shape is made to fit the curved grip part of the handle of the cane, and the product 9 of the present invention is placed so as to clamp the cane from above and cover the top part of the cane. By installing the product of the present invention at the bent part of the handle of a cane, the AVA area of ​​the palm can be cooled or heated. Furthermore, since the product of the present invention is made of rubber, it is elastic and comfortable, making it useful for elderly people.

[0025] [Tenth embodiment of the present invention] FIG. 10 shows a tenth embodiment of the present invention, in which the sixth embodiment of the present invention is attached to the portion of the handle 12 where the palm of the hand comes into contact. 1A is a front view of the steering wheel 12, with the present invention 9 provided at approximately the 2-3 o'clock and 9-10 o'clock positions when viewed clockwise. 1B is a cross-sectional view of the handle 12, and the semi-cylindrical cooling / heating device 9 of the present invention is placed over the handle at the position where the AVA comes into contact when the handle is gripped. The product of the present invention can be detachably attached to the handle. According to the tenth embodiment of the present invention, when one wishes to cool or warm one's palms while driving, one holds the product of the present invention, and when one feels that one's palms are overcooled or overheated, one holds a part of the steering wheel other than the product of the present invention, thereby enabling one to enjoy a safe and comfortable drive with less fatigue.

[0026] [Eleventh embodiment of the present invention] FIG. 11 shows an eleventh embodiment of the present invention, which is characterized in that a cooling or heating agent 4 is provided in a portion of a fingerless glove 13 that corresponds to the AVA portion 21 of the palm. Figure 11(A) shows a product of the present invention in which a vinyl or aluminum bag 41 is glued or sewn to a fingerless glove 13, a cooling or heating agent 4 is inserted into the bag, and the bag is sealed with a zipper or the like to cool or heat the AVA portion 21. 11(B) shows a product of the present invention in which a cooling or heating agent 4 in a drawstring bag 42 is inserted between the fingerless glove 13 and the AVA portion 21 of the palm to cool or heat the AVA portion. The drawstring bag may or may not be fixed to the fingerless glove.

[0027] It is preferable to cool the AVA portion 21 of the palm to a temperature that does not cause frostbite, i.e., 15° C. or higher. If a cooling agent (0° C. or lower) is placed directly on the skin, the skin temperature may drop too much, causing frostbite or other disorders, so the temperature is kept at 15° C. or higher by placing a nonwoven fabric or cloth between the cooling agent and the skin of the palm. The temperature at which the AVA portion 21 of the palm is heated is set to a temperature that does not cause burns.

[0028] It is preferable to have the skin temperature at 15 degrees or higher, but the present invention is not limited to 15 degrees or higher because it depends on the amount of heat input, palm temperature and other health factors. Furthermore, the material is not limited to a cooling agent, but may be a sheet that removes heat by evaporation heat as described in the second embodiment, a frozen polymer gel material, or ice. Various heating agents can be used in the same manner as described in the second embodiment.

[0029] According to the eleventh embodiment, by using fingerless gloves, the AVA area of ​​the palms can be cooled while the fingers of both hands can be moved freely, thereby significantly improving workability.

[0030] [Twelfth embodiment of the present invention] FIG. 12 shows the twelfth embodiment of the present invention, which, like FIG. 11(B), is characterized in that the cooling or heating agent 4 is placed between the AVA portion 21 of the palm and the fingerless glove 13, and is wrapped with nonwoven fabric multiple times. 12 shows a procedure for wrapping (A) a cooling or heating agent 4 with (B) nonwoven fabric 42, for example, in three layers (C), and (D) inserting the agent between the glove 13 and the AVA portion 21 of the palm. Note that (C) and (D) are cross-sectional views of the cooling agent and the palm.

[0031] It is preferable to adjust the thickness of the nonwoven fabric 43 and the number of times the cooling agent is wrapped so that the skin temperature of the AVA portion 21 of the palm is 15 degrees or higher. It is a 1.5 mm thick uneven nonwoven fabric, and wrapping the ice pack three times is preferable as it prevents the temperature of the palm from dropping excessively.

[0032] According to the twelfth embodiment of the present invention, the number of turns can be adjusted depending on the material and thickness of the nonwoven fabric, and the cooling or heating agent can be set to the optimum conditions for the wearer, allowing efficient cooling or heating.

[0033] We then carried out various insertion tests, measured the surface temperature, and investigated the conditions under which problems such as frostbite would not occur (Table 1). TIFF2025018848000002.tif100145

[0034] In this test, ice packs were placed under various materials and the temperature was measured from the surface. This confirmed what material and thickness would be best for contact with the skin. The results showed that the surface temperature of the ice pack was initially quite low, and that materials with low heat transfer and spaces, such as nonwoven fabric about 5 mm thick or foam cushioning sheets (or woven fabrics such as pile towels), would not cause a sudden drop in the surface temperature of the skin when in contact with the skin, and would be less likely to cause frostbite or other disorders.

[0035] [Thirteenth embodiment of the present invention] FIG. 13 shows a thirteenth embodiment of the present invention, in which double bubble cushioning sheets 44 are sealed 441 by welding or bonding to form a bag shape as a heat transfer buffer material, into which ice packs 4 are inserted (FIG. 4(C)), and the product is placed between ice packs 4 and the AVA area of ​​the palm inside fingerless glove 13. In this embodiment, a cooling agent is used, but a heating agent may also be used.

[0036] The air layer in the ice pack reduces the heat transfer efficiency, making it highly cushioned, comfortable to wear, and safe, as it allows the soft cool air to be felt on the AVA part of the palm. In addition, by using a transparent bubble cushioning sheet, the radiant heat (cold air) passes through the bubble cushioning sheet and hits the palm surface, so the heat (cold air) is transferred to the inside of the palm, making it even more comfortable.

[0037] Materials that reduce heat transfer efficiency and are soft and have air spaces, such as terry towel material, are also preferred. In this embodiment, the thickness of the heat transfer buffer material is about 8 mm for the double bubble buffer sheet 44, but the present invention is not limited to this and any thickness of 1 mm or more is included in the present invention.

[0038] [Fourteenth embodiment of the present invention] FIG. 14 shows the 14th embodiment of the present invention, and shows various forms of heat transfer buffer material placed between the ice pack 4 in a fingerless glove 13 and the AVA portion of the palm, including (A) a sealed bag-shaped six-ply nonwoven heat transfer buffer material 45, (B) a sheet-shaped six-ply nonwoven heat transfer buffer material 46, (C) a sheet-shaped two-ply air bubble cushioning sheet heat transfer buffer material 47, and (D) a folded air bubble cushioning sheet 48 with an ice pack placed inside. The bubble cushioning sheet is positioned so that the flat surface touches the palm of your hand, making it feel smooth to the touch.

[0039] The materials used as the heat transfer buffer material are preferably the above-mentioned nonwoven fabrics, foam buffer sheets, and woven fabrics such as towels made of pile fabric, but are not limited to these. Sponges, foam materials, rubber, and woven fabrics (shirring fabric, checkered weave, or twill weave) may also be used. The number of overlapping heat transfer buffer materials is not limited to the number shown in FIG. 14 and is included in the present invention.

[0040] The heat transfer buffer material may be in any of a bag shape, a plate shape, and a sandwiched folded shape. The plate-like sheet is the same size as the ice pack. To stably place the sheet between the palm and the ice pack, it can be attached to the ice pack with double-sided adhesive or attached to the palm with medical adhesive tape. The heat transfer cushioning material is made in plate form, which has the advantage of eliminating the stiff feeling in the palm of the hand and making it easier to work with the fingertips.

[0041] [Fifteenth embodiment of the present invention] FIG. 15 shows a fifteenth embodiment of the present invention, in which the tip of an armrest 101 of a chair 1 is formed into a bag-shaped portion 102, and a cooling or heating agent 4 and an armrest pipe 103 are inserted into the bag-shaped portion. The material of the armrest portion 101 may be any material such as vinyl sheet, wood, cloth, metal, etc., but vinyl sheet or cloth is preferable. The tip of the armrest 101 and the bag-shaped portion 102 are made of a thin, strong heat-conducting sheet material such as a vinyl sheet or cloth, so that the user can cool or heat the AVA area of ​​the palm of their hand at the tip of the armrest while sitting.

[0042] A cooling or heating agent 4 is provided in a bag-shaped portion 102 at the tip of an armrest 101 of a chair 1, and the user efficiently cools the AVA portion of the palm by gripping the armrest arm pipe 103. Also, if the cooling is insufficient, the ice pack may be placed so that it protrudes from the tip bag-shaped portion 102 of the armchair, and the cooling or heating agent 4 may be held directly. In addition, the cooling effect of the AVA area of ​​the palm can be further increased by placing a plastic bottle containing frozen water or other liquid in a cup holder provided on the armrest of an armchair and gripping it.

[0043] The thirteenth embodiment of the present invention is rational in that it can be used to fix the armrests of a folding chair and to cool the AVA area of ​​the palm of the hand, and has the effect of making it comfortable to use even outdoors.

[0044] [Effects of the present invention] The present invention can prevent heat stroke and the like by saving electricity during the current power shortage period, and also has the most efficient human body cooling effect by utilizing the AVA effect of Harvard University, and can effectively cool other parts of the human body. Furthermore, it makes it easy to carry around a cooling device and cool the necessary parts. [Industrial Applicability]

[0045] At present, the world is facing an increase in cases of heat stroke due to extreme heat and a dangerous shortage of electricity, so the industrial applicability of this invention to reduce heat stroke by saving electricity is extremely useful. [Explanation of symbols]
