DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat conductive glove used to protect hands from extremely low or high temperatures.

[0002]

BACKGROUND OF THE INVENTION Protecting hands from extremely low or high temperatures has heretofore been a difficult problem to solve. Hands, especially fingers, are relatively small and slender in limbs. Thus, the hand is immediately affected by the external temperature. Gloves can protect your hands from the outside environment, but in extreme cold or heat, you must wear thick gloves to keep your hands at normal or near-normal body temperature. However, the use of thick gloves reduces the agility of hand movements and, to an increased degree, inconveniences activities such as skiing, driving a racing car and working outdoors. Conventionally, various means are known for warming the palm and the finger of a glove. In the past, battery-powered resistance circuits have been used to warm gloves. Also, in a conventional glove warming system, there is a method in which a pocket is provided in a glove jacket, that is, a hood, and a heat dissipation pack is placed therein. There is also a method of simply inserting the heat dissipation pack into the glove.

[0003]

Generally, conventional electric systems are expensive and lack reliability and practicality due to the limited energy supply by batteries. With a battery operated system, it is difficult to obtain enough energy to warm the wearer's hand for an extended period of time. Further, a problem with the conventional method using the heat radiating pack is that only the part of the hand in contact with the heat radiating pack is warmed, and the generated heat is not transmitted to the finger part. Some conventional systems use air ducts or thermally conductive solid materials to transfer heat to the finger. However, it is difficult to transfer heat enough to heat the finger from the palm to the fingertip in a low temperature environment by air or a thermally conductive solid substance, and such a conventional method is useless and ineffective. Further, in the conventional method using an air duct or a heat conductive solid substance, there is a problem that the gloves are not bulky and comfortable for the wearer, and the movement and agility of the fingers are limited. Poor hand blood circulation is often associated with hand thermoregulation problems. In other words, poor blood circulation tends to make the hands cold. Blood circulation can be temporarily improved by massaging the hands. However, in order to perform the massage, usually, the work that has been performed must be stopped, and when gloves are worn, it is necessary to remove the gloves. Removing gloves hinders work, and in extreme cold or heat, conflicts with the purpose of wearing gloves. SUMMARY OF THE INVENTION An object of the present invention is to provide an inexpensive, practical, and simple system that can heat or cool fingers in a glove by inserting a glove-shaped liquid bag partially containing a liquid into the glove. It is to be.

[0004]

In accordance with the present invention, a glove-shaped bladder partially filled with liquid is inserted into the glove and the liquid in the bladder is applied to the wrist or palm of the glove lining. Heat or cool with the disposable heat dissipating or endothermic chemical pack provided. The heated or cooled liquid circulates to other parts of the hand or fingers by moving or squeezing the hand, or by gravity if the wearer turns his fingertip down. In this way, the heated or cooled liquid will move from the wrist or palm to the finger. When the wearer grips an object such as a tool or ski stock, the liquid in the bladder is pushed out of the finger portion and returns to the bottom of the bladder in contact with the chemical pack,
It is heated or cooled again. As described above, since the liquid heat transfer medium has a free-flowing property, the liquid can move around the finger and freely circulate around the wrist during the gripping operation. Restrictions on hand agility and mobility are minimized. Also, by adhering the liquid sac to a lining that can be inserted into an ordinary glove jacket, a circulating liquid heat transfer system for heating or cooling the entire wearer's hand can be provided.
In addition, the circulating fluid in the sacs provides a mass
The effect is obtained and helps keep the body temperature of the palm.

1 and 2 show a glove 10 according to the present invention.
Is shown. Here, the “glove” includes not only a five-finger glove but also a mitten-type glove. The jacket 12 of the glove 10 is
It is made from leather, vinyl, wool and other materials by an appropriate method. Under the hood 12, a heat insulating lining composed of a palm side lining 14 and a back side lining 16 is provided. The palm side lining 14 and the back side lining 16 also extend to the finger portion 15. The palm side lining 14 and the back side lining 16 are connected by an appropriate method. Here, it is simply shown as being connected by the stitch 21. The insulation lining should be made of a good-feeling material. Under the insulation lining, on the back side,
There is provided an inner lining layer 20 made of cotton, polyester, or any other nicely woven fiber (hereinafter referred to as non-insulating material) that allows free passage of heated or cooled air. The inner lining 20 is adhered to the palm side lining 14 and the back side lining 16 by a stitch 21 or an adhesive. A gap 19 for inserting a wearer's hand is provided between the back side lining 16 and the inside lining 20. A pocket 22 is formed below the inner lining 20, and is preferably provided at the wrist of the glove. The pocket is composed of a pocket material 24 and a pocket material 26, and both pocket materials are joined by a sewing stitch 28 at the pocket tip and both sides. Pockets are made of non-insulating material. The liquid sac 30 is arranged between the pocket 26 and the palm side lining 14 and is joined to the palm side lining 14 using an adhesive or the like. The bladder is a seamless fluid bag, preferably made of a latex, neoprene, polyurethane, vinyl or other elastic and waterproof material by known dipping processes. The material of the sacs is preferably 2-4 mm thick,
With that thickness, the bag is less likely to break and still conduct heat. One surface of the liquid sac 30 covers almost the entire pocket material 26, and the other surface includes the palm and the finger 1 of the wearer.
5 and almost all the way towards the fingertip 18 of the glove. Preferably, the bladder 30 has a shape conforming to the palmer lining 14 and the upper lining 16 and is generally rubber glove-like. The inside of the liquid sac contains a liquid heat transfer medium having a freezing point of substantially zero degrees or less. Examples of the liquid heat transfer medium include salt water and a silicon liquid such as a DOW200 liquid having a viscosity of 50 centistoke. The liquid volume used for adult gloves is about 85
Approximately 113g (3-4oz)
Reduce according to size. The amount of liquid to be put into the bladder is smaller than the maximum volume of the bladder so that the liquid can move through the bladder according to the movement of the wearer's hand, as described below. The bladder 30 is sealed at the base 31 after filling with the liquid, preferably by a double heat seal 32 or a mechanical sealing method such as a strap, rubber strap or plastic crimp (not shown). . Liquid 3 in liquid sacs 30
4 is heated or cooled by a temperature control device, such as a heat dissipating or endothermic chemical pack 36, depending on the glove wearer's choice. The pack is inserted into the pocket 22 as required by the wearer. One suitable such radiator pack is The HeatFactory Inc., Mission Viejo, California, United States of America.
One is sold under the trademark "eat Factory." It can dissipate heat energy for 6 to 12 hours depending on the ambient temperature and is disposable. Disposable chemical cooling packs of the same type are also commercially available. When the chemical pack is squeezed, the chemicals mix and cause an endothermic or heat-dissipating reaction that can be sensed from outside the pack.

FIGS. 3 to 5 show another embodiment of the present invention. This embodiment is a backing unit that is inserted into a ready-made lined glove jacket. The glove body itself is not shown. In this embodiment, a porous backside lining 50 is joined to a backside inner lining 52 and a palmer side inner lining 54. The back side inner lining 52 and the palm side inner lining 54 are made of non-insulating material, and the respective linings 50, 52, 54 are connected by a stitch 55. A gap 58 for inserting the wearer's finger is provided between the linings 52 and 54. The pocket 60 opened downward has a palm-side inner lining 54 and a pocket 6.
2 is formed by sewing together as shown by a stitch 63. The pocket 62 is also non-insulating material. The liquid sac 64 configured in the same manner as described above is in contact with the pocket 60, and further extends almost all the way to the fingertip 56 along the palm-side inner lining 54. The bladder contains a liquid 66 of the same type as described above. The liquid sac 64 is bonded to the pocket 62 and the palm inner lining 54 with an adhesive, and is sealed at the bottom by a double heat sealing 70 or a mechanical sealing method (not shown) as in the first embodiment. Be worn. A heat-dissipating or endothermic temperature control device 68 similar to that described above is inserted into the pocket 60. The entire unit consisting of the bladder 64, the inner linings 52 and 54, the porous backing lining 50 and the temperature controller 68 is inserted into a ready-made lined glove.

[0007]

The present invention can be used simply and effectively. The wearer need only insert the temperature control device into the pocket before or after wearing the glove. Exposure of the temperature control device to air or manipulation of the wearer's finger and hand initiates a chemical reaction within the temperature control device. The warm or cold generated by the temperature control device is transmitted through the pocket to the liquid contained in the portion of the liquid sac in contact with the pocket. Thereby, the liquid is heated or cooled. The heated or cooled liquid circulates due to gravity or the normal hand movements of the wearer. As the liquid circulates, the heated or cooled liquid moves from the palm to the fingertips, and at the same time, transmits the temperature of the liquid to the tissue of the hand or finger in contact with the liquid, warming or cooling the tissue of the hand or finger. I do. For example, if the wearer grips the tool or ski stock, the liquid in the bladder will be pushed out of the finger and will return to the palm of the bladder in contact with the temperature control device. The free flowing characteristics of the liquid heat transfer medium provide comfort and do not significantly limit the agility and operability of the wearer's hand movements. This is because, when it becomes necessary for the wearer to move his finger quickly, the liquid can freely circulate in the liquid sac and move to a part away from the finger such as the wrist. Free flowing liquid also has the massaging effect of hand tissue in contact with the liquid, improving blood circulation and further warming hand tissue. As described above, the present invention comprises a liquid sac provided on the palm side of a glove. However, it is also possible to form a pocket on the back side of the glove and to place the liquid sac and temperature control device on the back side of the glove. Further, it goes without saying that those skilled in the art can easily add various improvements to the present invention. Therefore, the claims of the present invention are:
It is intended to include all equivalent structures that fall within the scope and spirit of the invention.
