Description

  The present invention relates to a structure that keeps gloves and socks warm to fingertips using heat from a heat source body that stores heat by an external action and transfers heat to the surroundings.

When working outdoors in winter, fingertip biting reduces work efficiency as well as work safety. Therefore, for example, as shown in Patent Document 1, a pocket is provided on the back side of the hand of the glove, and by storing the disposable warmer in this pocket, the heat generated from the disposable warmer is used. The invention for improving the heat retention is already known.
In this glove, pockets are also provided on each finger side, and a disposable body warmer relatively smaller than the disposable body warmer placed on the back side of the hand is stored in this pocket, so that the heat retaining properties for the fingertips in the glove are also considered. It has become a thing.

  Moreover, as shown in Patent Document 2, an outer bag that is branched into four so that the tip extends to the fingertip is provided on the back side of the hand of the glove, and an electric heating circuit including four extension pieces is accommodated in the outer bag. In addition, a glove having a structure in which the fingertip in the glove is heated by the heat from the extension piece of the electric heating circuit by providing a storage bag for storing the power supply for supplying electricity to the electric heating circuit on the back of the hand of the glove is already known.

However, in the configuration of the glove shown in Patent Document 1, the size of the disposable body warmer accommodated in the pockets on the side surfaces of the fingers is relatively small, and therefore the amount of heat generated is also relatively small. It is not easy to properly warm the fingertips in the gloves using only
Moreover, in the structure of the glove shown in patent document 1, since the warmer of a relatively small disposable body warmer is used as a heat source, there is a problem that the heat generation time of this disposable body warmer becomes relatively short, and replacement of the disposable body warmer However, there is a problem that the entire operation becomes complicated due to the replacement of the disposable body warmer.
Furthermore, in the configuration of the glove shown in Patent Document 1, a disposable body warmer is disposed on the side surface of each finger of the glove, so that this disposable body warmer becomes an obstacle when bending the joint of the finger and lowers the work efficiency. Have.

  On the other hand, in the configuration of the glove shown in Patent Document 2, since electricity is supplied from the power source to the electric heating circuit to keep the fingertips in the gloves warm, it can be used for a long time. Is stored in a glove pocket or a storage bag, so that the gloves are relatively heavy. Further, there is a disadvantage that the extension piece of the electric heating circuit becomes an obstacle when the finger joint is bent and the work efficiency is lowered.

  Accordingly, an object of the present invention is to provide a glove or a sock having a heat retaining function capable of sufficiently warming even the fingertip in consideration of an operation of bending a finger joint while suppressing an increase in weight. And

  A glove or sock having a heat retaining function according to the present invention includes a limb main part storage part capable of storing from the base of a human hand or toe to the wrist or ankle, and the limb main part storage part. A heat source capable of storing heat by external action and transferring this heat to the surroundings in a glove or sock having a heat retaining function and having a finger storage part capable of storing fingers of hands or toes The body is arranged on the back side of the limb of the limb main part storage part, and the limb main part storage part and the finger storage part transmit heat from the heat source body to the fingertip side of the finger storage part. A thread mainly composed of a heat conductive fiber is woven so that the above can be achieved (claim 1). Here, the number of finger storage units may be 1 or more and 5 or less. Moreover, metal fibers, such as copper, are used for a heat conductive fiber, for example. Furthermore, examples of the external action include heating by electromagnetic waves and heating by boiling water.

  As a result, the heat from the heat source body arranged on the back side of the limb main part storage part transmits the yarn made of the heat conductive fiber woven in the limb main part storage part and the finger storage part. Since it is transmitted to the finger storage chamber side of the finger storage unit, it is possible to prevent biting of the fingertip of the hand or foot. Moreover, since it is not necessary to install an electric heating apparatus in a glove or a sock, the increase in the weight of a glove or a sock can be suppressed.

  Particularly, in the glove or the sock having a heat retaining function according to claim 2, the finger storage unit is configured to determine a ratio of the thermally conductive fiber in a portion corresponding to a portion where a joint of a stored finger is bent, in addition to the finger storage unit. It is characterized by being relatively smaller than the part. In order to reduce the proportion of the heat conductive fiber, there are a case where the amount of the heat conductive fiber of the yarn made of the heat conductive fiber is reduced and a case where the number of the yarn having the heat conductive fiber amount is reduced. is there.

  Thereby, even if it uses hard metal fibers, such as copper, as a heat conductive fiber, it can prevent that the joint of the finger | toe of a limb becomes difficult to bend.

  Particularly, in the glove or sock having a heat retaining function according to claim 3, the heat source body is configured by storing a heat storage heat transfer agent in a small amount in each storage chamber of a bag body partitioned into a plurality of storage chambers. (Claim 3). The heat storage heat transfer agent is, for example, a gel-like material that can be repeatedly used by heating from the outside using a microwave oven or the like, and is a material that can be easily obtained in the market.

  As a result, even if the heat storage heat transfer agent is fluid or liquid, the heat storage heat transfer agent is stored in small portions in the bag storage chamber. Even if the instep of the foot is inclined, it is possible to prevent the entire heat storage heat transfer agent from being biased toward the lower side of the hand or foot. Moreover, the heat storage heat transfer agent can be repeatedly used by heating from the outside with a microwave oven or the like, and furthermore, since it can be easily obtained in the market, even if a glove or sock is provided with a heat retaining function, Increase in cost of gloves or socks is suppressed.

  In particular, in the glove or the sock having a heat retaining function according to claim 4, the bag body constituting the heat source body is a storage space defined by a back side portion of the limb main part storage portion and a thin cover. (Claim 4). The storage space may have an opening communicating with the outside, and the opening may be freely opened and closed with a normal fastener, a hook-and-loop fastener, or the like.

  This makes it possible to remove the heat conductive fiber from the heat source body relative to the thin cover that is not in direct contact with the human hand or the back of the foot, relative to other parts of the glove or sock. The transmitted heat is efficiently transmitted to the main part of the limb through the cover. In addition, it is possible to take out only the bag body in which the heat storage heat transfer agent is stored from the storage space of gloves or socks and perform heating with a microwave oven or the like.

  As described above, according to the first to fourth aspects of the present invention, heat from the heat source body arranged on the back side of the limb of the limb main part storage part is transferred to the limb main part storage part and the finger storage part. Since the heat from the heat source body can be reliably and efficiently transmitted to the finger storage chamber side of the finger storage unit by transferring the heat conductive fiber woven into the yarn through the yarn, the finger storage unit Since the fingertips of the limbs are kept warm by the heat possessed by the limbs, it is possible to prevent biting of the limbs and to improve the efficiency of work even when working outdoors in winter.

  In addition, according to the invention described in claims 1 to 4, since it is not necessary to install the electric heating device on the glove or the sock, an increase in the weight of the glove or the sock can be suppressed.

  In particular, according to the second aspect of the present invention, even when a hard metal fiber such as copper is used as the thermally conductive fiber, it is possible to prevent the joints of the fingers of the limbs from becoming difficult to bend. Even if it is attached, it is relatively easy to securely grasp a tool or the like, and the efficiency of work such as construction can be further improved.

  In particular, according to the invention described in claim 3, even if the heat storage heat transfer agent is fluid or liquid, the heat storage heat transfer agent is stored in small portions in the storage chamber of the bag body. Even if you move your hand or foot and tilt your hand or foot back, you can prevent the entire heat storage heat transfer agent from being biased to the lower side of your hand or foot. It is possible to prevent variations in temperature.

  In particular, according to the invention described in claim 4, the ratio of weaving the heat conductive fibers in the thin cover that is not in direct contact with the human hand or the back of the foot is relatively higher than other parts of the glove or the sock. By increasing the number, heat generated from the heat source body can be efficiently transmitted to the limb main part storage section through the cover. In addition, it is possible to take out only the bag body in which the heat storage heat transfer agent is stored from the storage space of gloves or socks and perform heating with a microwave oven or the like.

  FIGS. 1 to 3 show an example of the configuration of a glove 1 according to the present invention. This glove 1 is intended to protect a worker's hand from cold and / or injury from the worker.

  A glove 1 shown in FIG. 1 to FIG. 3 is continuous to a hand main part storage part 2 that covers from the base end of a finger of a worker's hand to the wrist, and an internal space 6 of the hand main part storage part 2. This embodiment has an internal space (not shown; the same applies hereinafter), and in this embodiment, is basically composed of a finger storage portion 3 that exists corresponding to the number of fingers from the thumb to the little finger. . However, the finger storage unit 3 of the hand is not limited to the five configurations shown in FIGS. 1 and 3, but is not illustrated, but only the finger storage unit 3 of one hand that stores everything from the thumb to the little finger. The finger storage unit 3 of the hand that stores the thumb and the finger storage unit 3 of the hand that stores from the index finger to the little finger are also configured. There may be.

  The hand main part storage unit 2 is provided with an opening 4 on the side opposite to the finger storage part 3 side of the hand, and the operator's hand and fingers can be moved from the opening 4 to the hand main part storage part 2. It can be inserted into the internal space 6 and the internal space of the finger storage part 3 of the hand. Further, as shown in FIG. 1 and FIG. 3, the portion in the vicinity of the opening of the opening portion 4 of the main hand portion storage portion 2 is closely attached to the entire circumference of the wrist of a person such as an operator by having the throttle portion 5. Thus, the heat accumulated in the internal space 6 of the glove 1 shown in FIG. 2 from between the wrist and the opening 4 may be prevented from escaping to the outside.

  By the way, as shown in FIGS. 1 to 3, in the glove 1, the heat source body 7 is arranged on the back side portion 2 a of the hand side when the hand is stored in the internal space 6 in the main hand storage portion 2. Has been.

  The heat source body 7 is basically composed of a sealed bag body 8 and a heat storage heat transfer agent 9 enclosed in the bag body 8. In this embodiment, the bag body 8 is formed in a lattice shape or A plurality of sealed storage chambers 11 (16 storage chambers 11 in this embodiment) are defined by the partition 10 extending in a cross-beam shape, and the heat storage heat transfer agent 9 is encapsulated in each storage chamber 11 in a divided manner. It has become a form. Thereby, even if the finger storage part 3 of the hand of the glove 1 faces upward during work, it is possible to prevent most of the heat storage heat transfer agent 9 from being biased to the wrist side of the bag body 8.

  The heat storage heat transfer agent 9 is in the form of gel, other fluid or liquid, and can store heat for a long time with heat supplied from the outside and radiates this accumulated heat to the surroundings. It is also possible to do. Furthermore, the heat storage heat transfer agent 9 can be repeatedly used by supplying heat from the outside. Examples of the component of the heat storage heat transfer agent 9 include, but are not limited to, one obtained by dissolving polyvinyl alcohol in water and one obtained by dissolving sodium carboxymethyl cellulose in water.

  And the bag body 8 in which the heat storage heat transfer agent 9 of the heat source body 7 is accommodated is, as shown in FIG. 2, the back part 2 a of the hand main part storage part 2 and the hand main part storage part 2. It is stored in a storage space 13 defined by a thin cover (cloth body) 12 which is a separate member. The storage space 13 is defined and the bag 8 is stored in the storage space 13, for example, as shown by the arrow 14 in FIG. After the body 8 is placed, as shown by the arrow 15 in FIG. 3, the cover 12 covers the bag body 8 from the outside of the bag body 8, and the back side part 2 a of the hand main part storage unit 2. The cover 12 and the back side part 2a of the hand main part storage part 2 are connected in a bag shape by means such as sewing. Although not shown, a bag can be obtained by providing a fastener on the cover 12 or temporarily connecting the entire periphery of the cover 12 with a hook-and-loop fastener without connecting to the back part 2a of the hand main portion storage portion 2. The body 8 may be detachable from the storage space 13.

  Moreover, the hand main part storage part 2, the hand finger storage part 3, and the cover 12 which comprise the glove 1 are made of only natural fibers or synthetic fibers made of animal leather, as shown in FIGS. The yarn 16 is woven with a yarn 16 having excellent thermal conductivity and a metal fiber (thermally conductive fiber) such as copper as a material. The yarn 17 is used as both a weft and a warp. At the same time, the weft yarn 17 and the warp yarn 17 are woven from the hand main portion storage portion 2 to the hand finger storage portion 3 while being in contact with each other.

  Thereby, the heat from the heat storage heat transfer agent 9 of the heat source body 7 is transmitted through the thread 17 and is transmitted to the fingertip side of the finger storage unit 3 of the hand. The heat from the heat agent 9 is reliably supplied, and it is possible to keep the fingers stored in the finger storage unit 3 and the fingertips warm.

  The number of yarns 17 woven in the main hand portion storage unit 2, the finger storage unit 3 and the cover 12 may not be uniform. That is, in the cover 12, as shown in FIG. 4, the number of the yarns 17 is relatively increased with an emphasis on increasing the efficiency of thermal conductivity from the heat storage heat transfer agent 9 to the surroundings. May be. This is because the cover 12 itself does not come into contact with the hand, so that there is little need to consider that the cover 12 becomes hot. Moreover, in the general site | part of the hand main part storage part 2 and the finger | toe storage part 3 of a hand, as FIG. 5 shows, the number of the thread | yarns 17 is the guarantee of heat conductivity, suppression of high temperature, It is the thing which aimed at the balance of. And in the site | part which covers the circumference | surroundings of the finger joint of the finger | toe storage part 3 of a hand, as FIG. 6 shows, the number of the thread | yarn 17 is relative with emphasis on making it easy to bend a finger joint. It may be less. Thereby, it is possible to improve the efficiency of the workability of the person who wears the gloves 1 and performs the work.
