BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(First embodiment)
FIG. 1 is a perspective view of a rechargeable body warmer according to an embodiment of the present invention, showing a state in which the rechargeable body warmer is flattened. 2A is a plan view of the body warmer of FIG. 1, and FIG. 2B is a side view of the body warmer. FIG. 3 is a cross-sectional view for explaining the internal structure of the warmer, and shows a cross section taken along the line AA in FIG.

As shown in FIG. 1, the rechargeable body warmer 1 according to the present embodiment is disposed on a surface of the main body 30 including a main body 30 including two cases 30 </ b> A and 30 </ b> B that are foldably connected via a hinge portion 34. The heating elements 13 and 13 are provided. Each case 30A, 30B is a housing made of resin or elastomer, and the heating element 13 is disposed at the approximate center of the upper surface thereof.
Here, the heating element 13 includes a plate-shaped heat transfer plate 15 and a heating member 17 (see FIG. 3, which will be described in detail later) disposed on the back surface thereof.

  The case 30 </ b> B has two concave portions 35 and 35 that are dug from the outside toward the center side on one side of the outer peripheral portion (side 31 </ b> B on the hinge portion 34 side). Correspondingly, convex portions 36, 36 that enter the concave portions 35, 35 are formed on one side of the outer peripheral portion of the other case 30A. The hinge portion 34 is configured such that the convex portions 36 and 36 enter the concave portions 35 and 35, and in this state, the shaft member 31 is passed in the vertical direction (see FIG. 1) as shown in FIG. . Thereby, case 30A, 30B is mutually connected so that rotation (foldable) is possible around the shaft member 31. As shown in FIG.

  The rotation range of the cases 30A and 30B is not particularly limited, but in this example, the rotation range is approximately 90 ° (see FIG. 4) to 180 ° (see FIG. 1).

As shown in FIGS. 2A and 2B, a concave portion 39 that is recessed by a predetermined depth from the upper surface side of the case is provided on one side (side on the hinge portion side) of the outer peripheral portion of the case 30A. It is formed along the edge on the 34th side. On the lower side of the recess 39, a member is left as the lower protrusion 38.
On the other hand, in the other case 30 </ b> B, a recess 39 ′ that is recessed from the lower surface side by a predetermined depth is formed, and the upper side is left as the upper protrusion 37.

As shown in FIG. 2B, the upper surface 38a of the lower protruding portion 38 and the lower surface 37a of the upper protruding portion 37 are substantially in surface contact with each other when the cases 30A and 30B are opened to about 180 °. This prevents the cases 30A and 30B from opening further in the direction of arrow B (approximately 180 ° or more).
Further, as shown in FIG. 4, when the cases 30A and 30B are bent at about 90 °, the corner 32 at the upper corner of the recess 39 on the case 30A side hits the upper surface of the counterpart case 30B, thereby No more closing.

Referring to FIG. 1 again, fixing means (12) for fixing the entire rechargeable body warmer 1 to clothes or the like is attached to the upper surfaces of the cases 30A and 30B. This fixing means is, for example, a U-shaped hook-and-loop fastener 12 surrounding three sides of the heat transfer plate 15. The height of the upper surface of the hook-and-loop fastener 12 may be the same as the height of the upper surface of the heat transfer plate 15 or may be slightly higher than the upper surface of the heat transfer plate 15.
In addition, when using the hook_and_loop | surface fastener 12, it is preferable that the hook or loop is provided in the other party.

Further, in addition to the hook-and-loop fastener 12, the fixing means may use an adhesive material, an adhesive tape, a fastener, a hook, or the like. The hook-and-loop fastener 12 is not limited to the U-shape, and may be three linear ones attached along the three sides of the heat transfer plate 15.
Here, as the adhesive material, acrylic-based, SEBS-based, SBS-based, SIS-based, and the like containing petroleum-based resin can be used. For the surface fastener, a polyolefin resin such as a nylon resin, a polyester resin, or a PP resin can be used.

Next, the internal structure of the rechargeable body warmer 1 of this embodiment will be described with reference to FIG.
As shown in FIG. 3, the heat transfer plate 15 is arranged on the upper surfaces of the cases 30A and 30B as described above. A thin plate-like heat generating member 17 is attached to the center of the back surface of the heat transfer plate 15. As an example, the heat generating member 17 is a PTC (Positive Temperature Coefficient) heater that generates heat when a voltage is applied. Heat from the heater is transmitted to the heat transfer plate 15 so that the entire heat transfer plate 15 is heated. ing.

  As the heat transfer plate 15, a material having excellent thermal conductivity such as metal, conductive plastic, conductive rubber, conductive elastomer, or the like can be used. The heating member 17 can be variously used in addition to the PTC heater, such as a planar heater.

  Batteries B1 and B2 for applying a voltage (powering) to the heat generating member 17 are disposed in the cases 30A and 30B, respectively. As this battery, for example, a rechargeable lithium ion battery, nickel hydride battery, nickel, cadmium battery, lithium battery, lithium polymer battery, fuel cell, calcium ion battery, or the like can be used. The battery may be externally attached to the cases 30A and 30B.

  Although a detailed description of the circuit configuration is omitted, an external power supply socket 43 for charging the batteries B1 and B2 is provided in a part of the case 30A (see FIG. 3). In this case, the batteries B1 and B2 are charged by connecting a power cord for charging (not shown) to the socket 43.

Inside the case 30B, a microcomputer A that controls whether or not to apply a voltage to the heat generating member 17 (ie, ON / OFF control of a warmer) and temperature control of the heat generating member 17 is arranged.
As an example, the microcomputer A adjusts the temperature of the heat generating member 17 by adjusting the voltage value or current value from the batteries B1 and B2 (in the following, an example in which the voltage value is adjusted will be described).
Temperature sensors (thermistors) 19 a and 19 b are provided at two locations on the back surface of the heat generating member 17 and the back surface of the heat transfer plate 15 so that the microcomputer A can adjust the temperature of the heat generating member 17. The microcomputer A adjusts the voltage values from the batteries B1 and B2 as appropriate based on the detection results of the two sensors 19a and 19b, and adjusts the temperature of the heat generating member 17 and thus the heat transfer plate 15. Since the sensors 19a and 19b are provided at two locations of the heat generating member 17 and the heat transfer plate 15, more accurate temperature adjustment is possible.

  As an example, from the viewpoint of preventing low-temperature burns, the microcomputer A sets the temperature of the heat transfer plate 15 to a predetermined set temperature (40 ° C. to 50 ° C.) so that the body surface temperature is in the range of 38 ° C. to 42 ° C. ° C). That is, based on the detection results of the temperature sensors 19a and 19b, the battery voltage is controlled to increase when the temperature of the heat transfer plate 15 is lower than the set temperature, while the temperature of the heat transfer plate 15 exceeds the set temperature. In some cases, the output of the power supply is controlled to be lowered stepwise or continuously.

  Although not shown, in the rechargeable body warmer 1 of the present embodiment, an operation switch is provided in a part of the main body 30, and the user operates the switch to turn on the body warmer 1. / OFF can be switched.

  The rechargeable body warmer 1 of this embodiment can set several operation patterns. For example, “continuous operation mode” that operates while the switch (not shown) is turned on to maintain an appropriate temperature, or “automatic stop mode that automatically turns off after a predetermined time has elapsed after the switch is turned on. Etc. In each mode, temperature adjustment such as “high temperature” and “low temperature” is further possible. A more specific example of temperature adjustment will be described later with reference to other drawings.

Next, a usage example of the rechargeable body warmer 1 of the present embodiment configured as described above will be described with reference to FIGS. 5 and 6.
The warmer 1 can be used by contacting the sole as shown in FIG. Many people who are “cold” have very poor blood flow at the end of the foot and have cold feet even in summer. The rechargeable body warmer 1 of the present embodiment can be used by attaching it to a sock to improve the cooling performance. In this case, the body surface temperature is preferably 42 ° C. or lower so as not to cause low-temperature burns. Moreover, it is also possible to use the warmer 1 attached to the sole in this way at bedtime.

  In such a form of use, according to the configuration of the present embodiment, the fixing means (the hook-and-loop fastener 12) provided around the heat transfer plate 15 sticks to the socks, so that the entire body warmer can be attached without using a special attachment. It can be fixed well on the back.

  Further, in the rechargeable body warmer 1 of the present embodiment, the cases 30A and 30B can be bent. Therefore, when the soles are applied in this way, the cases 30A and 30B follow the shape of the soles. Bends. In this example, the electric heating plate 15 of the case 30A is in contact along the front side of the bulging portion of the base of the thumb on the sole, and the case 30B is in contact along the rear side. According to the configuration of the present embodiment, since the heat transfer plates 15 and 15 of the cases 30A and 30B can be satisfactorily brought into close contact with or in close contact with the soles, the thermal effect is improved.

  As shown in FIG. 6, the rechargeable body warmer 1 of this embodiment can also be used on the shoulder from the underwear. In this case, the body 1 is folded along the shoulder curve so as to wrap the trapezius muscle of the shoulder (that is, with the electric heating plate 15 of each case hitting the front and back of the trapezius), Can be warmed up effectively. Also in this case, since the hook-and-loop fastener 12 (see FIG. 1) is attached to the underwear and the entire body warmer is fixed, the body warmer 1 does not slide off from the shoulder.

As described above, the rechargeable body warmer 1 of the present embodiment can change its shape along the soles or shoulders, so that the heat transfer plate 15 can be brought close to or in close contact with a part of the body. it can. In addition, since the fixing means such as the hook-and-loop fastener 12 is provided on the upper surfaces of the cases 30A and 30B, the rechargeable body warmer 1 can be satisfactorily fixed to the clothes.
Moreover, since it is driven by the built-in batteries B1 and B2, a power cord or the like is unnecessary, and it can be used anywhere. Since the batteries B1 and B2 are rechargeable, it is advantageous in that they can be used repeatedly.

  In addition, the rechargeable body warmer 1 of the present embodiment incorporates the microcomputer A and the temperature sensors 19a and 19b (see FIG. 3), so that the temperature of the heat generating member 17 can be adjusted. A comfortable temperature can be maintained.

  Here, a specific example of temperature adjustment will be described with reference to FIG. FIG. 7 is a graph showing an example of a person's daily body temperature and temperature adjustment of the rechargeable body warmer 1 (from cure insomnia / Yoichi Nakazawa / Health Dojinsha / December 1995), with the vertical axis Temperature and horizontal axis are time zones. In FIG. 7, a lower broken line connecting round points indicates a change in body temperature, and a broken line connecting square points indicates a warmer temperature. In this example, an example of a person who sleeps in a time zone of 21: 00 to 6:00 is shown.

  The human body temperature in this example is about 37 ° C. during the daytime, and gradually decreases to about 36.5 ° C. from 19:00 to 23:00. It keeps about 5 ° C and gradually rises to about 37 ° C again from 4:00 to 6:00 in the morning. In the state where the body temperature is low as in the time zone from 23:00 to 4:00, the warmer 1 does not need to be so hot. Since it is considered that the temperature of the warmer 1 is easily felt immediately after going to sleep and just before getting up, the warmer 1 only needs to be hot during this time period.

  Therefore, in the rechargeable body warmer 1 of the present embodiment, as shown in the graph, the temperature of the body warmer (temperature of the heat transfer plate 15) immediately after going to bed (21:00 to 23:00) as shown in the graph by microcomputer control. As an example, the temperature is set to 40 ° C., the temperature in the subsequent time zone (23:00 to 4:00) is slightly lowered to 38 ° C., and the temperature in the time zone immediately before getting up (4:00 to 6:00) is increased again. 40 ° C. According to such control, the consumption amount of the batteries B1 and B2 in a predetermined time zone (22:00 to 4:00) can be suppressed, so that the usage time in one charge can be extended.

  The timing for starting the temperature control may be when a switch (not shown) provided in the case is turned on. That is, the temperature control may be performed from the time when the switch is turned on.

Alternatively, the microcomputer A may have a built-in clock function, and the temperature control may be performed based on the time of the clock function.
Further, the rechargeable body warmer 1 is further provided with a temperature detecting function for detecting the body temperature of the person, and the temperature of the body warmer 1 is lowered (when the body temperature is lowered) due to the detected body temperature (when the body temperature is lowered). For example, it may be configured to be 38 ° C.).

  As mentioned above, although one form of this invention was demonstrated, in the rechargeable body warmer of this invention, it has three or more cases, and these cases may be connected so that bending is possible mutually.

Next, a flexible elastic sheet interposed between the body 1 and the body will be described again with reference to FIG.
As shown in FIG. 3, in the warmer 1, a flexible elastic sheet 45 may be provided on the surface of the heating element 13. In this example, the sheet 45 is provided so as to cover each of the heating elements 13. However, the present invention is not limited to this, and the entire surface (upper surface) of the warmer 1 may be covered with one sheet 45. Good.

  The material of this sheet may be either a material having high thermal conductivity or a material having high specific heat (gel materials, elastomer materials, rubber materials, etc. as examples of materials having high specific heat). Moreover, the sheet | seat surface has adhesiveness and the sheet | seat which sticks to clothes etc. may be sufficient.

  The gel material is glycerin, water, etc., polyacrylic acid, sodium polyacrylate, sodium polyicotanate, cross-linked sodium polyacrylate, cross-linked acrylic polymer, cross-linked polyacrylic acid, CMC, HPC, polyvinyl Gels hardened with alcohol, gelatin, gum arabic and gel hardening agent (aluminum hydroxide / magnesium hydroxide / calcium hydroxide, aluminum chloride, aluminum sulfate, potassium alum, zinc oxide, synthetic aluminum silicate, etc.) can be used It is.

  Rubber materials include styrene, butadiene rubber, natural rubber, nitrile rubber, chloroprene rubber, butyl rubber, silicon rubber, chlorosulfonated polyethylene rubber, fluorine rubber, ethylene, propylene rubber, urethane rubber, etc. Can be used.

  Elastomer materials are polyurethane, olefin, styrene, polyester, polyamide, fluorine, syndiotactic 1, 2PB elastomer, chlorinated ethylene copolymer cross-linked polymer alloy, chlorinated polyethylene, ester, halogen polymer alloy type. An elastomer or the like can be used.

  By providing such a flexible sheet 45, the fit to the body is improved, so that heat can be transmitted more efficiently. When the specific heat of the sheet is high, the heat storage property can be improved. On the other hand, when the sheet has high thermal conductivity, there is an advantage that the heat from the heating element can be smoothly transferred to a part of the body.
