Description

  The present invention relates to a glove that can heat a fingertip or the like for heating.

  A warming glove that does not use an electric heater has been proposed (for example, Patent Document 1).

  Conventional warming gloves use a catalytic combustion heating device that uses a catalytic reaction to oxidize liquefied fuel gas to heat the heating medium, and the heating medium passes through the heating medium passage disposed on the entire surface of the glove. Circulate. Note that the heat medium is circulated through a dedicated circulation device.

JP 2001-115317 A

  When such a conventional technique is used, the heat source unit for heating and circulating the heat medium is combined with a fuel tank for liquefied fuel gas and a circulation device for the heat medium in addition to the catalytic combustion heating device. However, it is difficult to form a glove integrally with gloves, and the problem of poor usability and practicality is unavoidable.

  Therefore, in view of the problems of the prior art, the object of the present invention is to realize a good usability and increase the practicality by mounting a flexible bag body combined with a heating element on a glove body. It is to provide gloves that can.

  In order to achieve the above object, the structure of the present invention includes a glove body, a flexible bag body that houses a heat medium and is mounted on either the palm side or the back side of the glove body, and the bag body. A heating element to be combined and a circulation path for the heat medium attached to the glove body and extending from the outlet port of the bag body to the inlet port, the circulation path including a branch path attached to each finger part of the glove body The gist of the bag body is that when the glove body is attached to the hand and the fingers are bent and stretched, the internal volume changes to a large and small size, exerts a pump action, and circulates the heat medium in the circulation path.

  The outlet port and the inlet port can each be equipped with a check valve in a predetermined direction, and the circulation path can be provided with a pressure adjusting chamber in the middle.

  The heating element may be attached to the upper surface of the bag body or may be sandwiched between the bag bodies that are folded in two.

  When the structure of the present invention is adopted, the bag body mounted on the glove body changes its internal volume by gripping the hand wearing the glove body in a fist-like shape and bending the fingers to open it. The pumping action is exhibited, and the heat medium can be circulated through the circulation path for heating. This is because the heat medium in the bag is heated by the heat from the heating element integrated with the bag. In addition, the bag body mounted on the palm side of the glove body is crushed in the palm by bending the fingers to reduce the internal volume, and when the fingers are extended, it returns to its original shape and internal volume by elasticity. In addition, the bag mounted on the back side of the glove body is thinly deformed because the middle finger joint (MP joint) at the base of 4 fingers from the index finger to the little finger protrudes toward the mountain side by bending the finger. When the internal volume is reduced and the fingers are extended, the original shape and internal volume are restored by elasticity. Since the bag body with the heating element is integrally mounted on the glove body together with the circulation path for the heat medium, the glove body is sufficiently light, can be used with good usability, and can improve practicality.

  However, the palm-side bag shall be mounted on the glove body in a position where it can be easily gripped in the palm by bending the fingers, and the back-side bag is the 4 middle metacarpophalangeal joints from the index finger to the little finger. It shall be mounted at a position corresponding to all or part of the above. The heating element is preferably a disposable body warmer (JIS S 4100) which is combined with the bag body in order to heat the heat medium in the bag body and utilizes the oxidation action of iron powder. Moreover, since the circulation path of the heat medium includes a branch path attached to each finger portion of the glove body, it is possible to effectively heat the fingertip portion that is likely to feel a cool feeling. In addition, although a heat medium may be water, you may use nontoxic antifreeze liquids, such as a liquid mixture of glycerol and water. However, the glove body here is a five-finger glove-shaped base material, which is formed of a flexible material.

  The outlet port and the inlet port of the bag body are provided with check valves in the outflow direction and the inflow direction of the heat medium, respectively, so that the pump action of the bag body can be surely exhibited.

  If a pressure adjusting chamber is provided in the middle of the circulation path, there is no possibility that the pressure in the circulation path will rise excessively when the inner volume of the bag body is reduced and the heat medium flows out to the circulation path.

  The heating element may be attached to the upper surface of the bag body mounted on the surface of the glove body, or may be sandwiched between the bag bodies folded in two. According to the latter, the heat from the upper and lower surfaces of the heating element can be transmitted to the heating medium in the bag, and the heating of the heating medium is more effective.

  The glove body 11 is formed in a glove shape that fits the user's hand with a thin flexible material. The glove body 11 may be divided into right-hand use and left-hand use, or may be used for both left and right.

  The bag body 12 has appropriate elasticity and flexibility, and is filled with a heat medium (not shown). The bag body 12 is formed with an outlet port 12a and an inlet port 12b. The outlet port 12a is internally provided with a check valve 12a1 in the direction of outflow of the heat medium, and the inlet port 12b has an inflow direction of the heat medium. The check valve 12b1 is internally provided. The bag body 12 is hermetically sealed except for the outlet port 12a and the inlet port 12b, and the formation positions of the outlet port 12a and the inlet port 12b can be arbitrarily changed regardless of FIG. The bag body 12 can be formed by water-tightly bonding two thin sheet materials through, for example, a narrow binding margin 12c with four rounds (FIG. 2). However, FIGS. 2A and 2B are a top view and a side view of the bag body 12 and the heating element 13 that are combined together, respectively.

  The circulation path 20 includes branch paths 23, 23... Attached to the finger portions 11 a of the glove body 11 in addition to the main paths 21 and 22 connected to the outlet port 12 a and the inlet port 12 b of the bag body 12 ( FIG. 1). Therefore, the heat medium flowing out from the outlet port 12a of the bag body 12 branches from the main path 21 to the branch paths 23, 23... Of each finger part 11a, and returns to the bag body 12 through the main path 22 and the inlet port 12b. It circulates in the direction (arrow direction in FIG. 1).

  The heating element 13 is integrally attached to the upper surface of the bag body 12 on the surface of the glove body 11 (FIGS. 1 and 2). The heating element 13 uses a flexible disposable body warmer. The heating element 13 may be combined with the bag body 12 in a replaceable manner, or may be combined in a non-replaceable manner and the entire body including the glove body 11 may be disposable.

  The bag body 12 with the heating element 13 may be mounted on the palm side of the glove body 11 (FIG. 3A) or on the back side (FIG. 3B). However, in FIGS. 3A and 3B, when the glove body 11 is attached to the user's hand H, the bag body 12 has a glove body 11 and a circulation path so that the relative position with respect to the hand H can be easily understood. Illustration of 20 is omitted.

  Such a glove heats the heating element 13 on the bag body 12 to heat the heat medium in the bag body 12, and changes the internal volume of the bag body 12 to a large or small size to exert a pump action. The heated heat medium can be circulated through the branch paths 23, 23... Of the circulation path 20 to effectively warm the user's hand H including the fingertip portion. In order to change the internal volume of the bag body 12, the palm side bag body 12 is crushed by bending the finger of the hand H wearing the glove body 11, or the back side bag body 12 is thinly deformed. After the inner volume of the bag body 12 is reduced, the fingers are stretched to return the bag body 12 to its original shape and inner volume by elasticity.

  In the above description, the glove body 11 may have a double structure as a whole by attaching a thin protective cover material 11b (the chain line in FIG. 1). In addition, the cover material 11b shall cover all the glove body 11, the bag body 12 with the heating element 13 on the glove body 11, and the circulation path 20 including the branch paths 23, 23.
