Description

SPECIFICATION Gloves Background of the Invention This invention relates to novel and improved gloves or mittens (hereinafter called 'gloves') for protecting human hands from cold weather.

Generally, persons wear gloves on their hands so that the material of the glove protects their hands from the cold weather and keeps the hands warm both by preventing the escape of heat and by preventing cold winds contacting the hands.

However, conventional gloves fail satisfactorily to protect human hands from severe cold.

Furthermore, when conventional gloves get wet with moisture from water or snow, such gloves cannot perform satisfactorily.

Therefore, the present invention aims to provide a novel and improved glove which can effectively eliminate or alleviate the disadvantages inherent in conventional gloves and which can positively keep the human hand warm even under severely cold weather conditions without relying upon the material of the glove itself for attaining the function of keeping-warm.

The principal object of the present invention is to provide a glove which can positively heat the wearer's hand by means of a positive heating means which concurrently performs the usual adiabatic function.

According to one aspect of the present invention a glove carries a bag containing an exothermic composition.

One specific embodiment of the present invention provides a glove which includes as the heating means an exothermic means comprising a water-proof and air-pervious bag and an exothermic composition enclosed in the bag and comprising a mixture of metal powder (iron powder) and oxidation acceleration catalysts such as salt, water and active carbon. The exothermic composition is adapted to effect a moderate exothermic oxidation reaction with the open air coming into contact with the exothermic composition through the fine pores in the pocket and bag, and to flex yieldingly following the movement of the wearer's hand without offering resistance to the movement of the hand. Since the exothermic oxidation reaction of the exothermic composition with the open air is moderate, there is no possibility of burning the wearer's hand thereby providing a safe glove.

According to a specific aspect of the present invention a glove comprises a glove body, an airpervious and water-impervious pocket sewn to a selected portion of the body leaving a portion of said pocket open to provide a opening to the pocket, closure means for normally closing the opening and an exothermic means received in the pocket and comprising an air-pervious bag and an exothermic composition received in the bag.

The exothermic composition is so chosen that it can contact a sufficient amount of the oxygen contained in the open air which flows into the exothermic composition through the fine pores in the pocket and bag whereby the composition effects a moderate exothermic oxidation reaction with the open air for keeping the wearer's hand warm.

The present invention preferably provides a glove including as a heating means an exothermic composition, the exothermic oxidation reaction function of which is not adversely affected by moisture even when the glove gets wet.

One particularly useful advantage of present invention is to be able to warm golf balls by putting them in the pocket of the glove while the golfer is playing, thereby extending the distance of carry of the ball.

According to a specific aspect of the present invention, a glove comprises a fabric body, a water-proof, air-pervious and water-impervious fabric pocket sewn to a selected portion of said body leaving a portion of said pocket open to provide the opening of the pocket, a closure means attached to said body adjacent the opening of the pocket for normally closing the opening and an exothermic means contained in said pocket and comprising a water-proof and air-pervious fabric bag and exothermic composition contained in the bag.

The invention may be carried into practice in various ways but certain specific embodiments will now be described by way of example with reference to the accompanying drawings, in which: Figure 1 is a plan view of a first embodiment of the glove or mitten according to the invention; Figure 2 is a vertically sectioned view of the glove of Figure 1 taken along substantially the line x-x; Figure 3 is a perspective view of a bag-type exothermic means arranged to be positioned on the body of the glove with a portion of the bag cut away; Figure 4 is a fragmentary vertically sectioned view of a second embodiment of glove according to the invention in which the exothermic means is positioned on the back of the body of the glove; and Figure 5 is a fragmentary vertically sectioned view of a third embodiment of glove according to the invention in which the exothermic means is positioned on the inside of the body of the glove.

The present invention will firstly be described by reference to Figures 1 to 3 in which a first embodiment of glove or mitten according to the invention is shown. The glove body 1 is formed of a conventional piece of cloth. A substantially square-shaped pocket 2 is sewn to the finger portion 3 of the body 1 as shown by reference numeral 5, leaving the lower side of the pocket open as shown in Figures 1 and 2 thereby to provide an opening 4 of the pocket. The pocket 2 is formed of a piece of cloth which is air-pervious, water-impervious and flexible. The sewn area 5 of the pocket 2 is sealed by a water-proof tape or the like 6.

The pocket 2 receives an exothermic means 7 of which description will be made hereinafter and a slide fastener 8 is sewn to the opening 4 of the pocket 2 so that the exothermic means 7 is prevented from falling down out of the pocket. By opening the opening 4 of the pocket 2, the exothermic means 7 can be taken out of the pocket.

The exothermic means 7 comprises a bag 9 such as a water-proof woven or non-woven fabric bag and a powdery exothermic composition 10 received in the bag 9. The bag 9 thus has such a porosity that the bag exhibits an air-pervious characteristic and the exothermic composition comprises a mixture of metal powder such as iron powder and oxidation acceleration catalysts such as coal active carbon, complementary water agent, salt and water. The exothermic composition effects a moderate exothermic oxidation reaction with the open air when the composition contacts the open air.

One example of the exothermic composition comprises by weight percent: 200 mesh reduced iron powder 60% 100 mesh coal active carbon 12% complementary water agent 4% (bernilite) sodium chloride 4% water 20% The components are fully admixed to provide the powdery exothermic composition useful in the present invention.

Figure 4 shows a second embodiment of glove according to the invention which is substantially similar to the first embodiment of Figure 1 to 3 except that the pocket 2a, having the abovementioned exothermic means 7 received therein, is sewn to the back of the glove body 1 leaving the lower side of the pocket open to provide the opening 4 which is normally closed by suitable closing means such as a closure flap 12 and a snap hook 13.

Figure 5 shows the third embodiment of glove which is substantially similar to the second embodiment except that the pocket 26 is sewn to the inside of the body of the glove.

As will be clear from the foregoing description of the preferred embodiments of gloves of the present invention, since the exothermic means 7 is received in the water-proofed pocket 2, 2a or 26 sewn to a desired area of the glove body 1, the pocket and bag 9 are formed of pieces of fabric which is air-pervious and flexible and the exothermic composition 10 of the exothermic means 7 effects a moderate exothermic oxidation reaction with the open air flowing into the composition through the fine pores in the fabric of the pocket and bag, when the user wears the glove, the entire hand of the user received in the glove is warmed and maintained in the warmed condition thereby to accelerate the circulation of blood in the user's hand.Since the exothermic composition is in the form of powder, the exothermic composition flexes yieldingly following the movement of the user's hand, and thus does not offer any resistance to the movement of the hand. Furthermore, since the exothermic composition effects only a moderate exothermic oxidation reaction with the incoming open air, there is no possibility of burning the user's hand and thus, the gloves of the present invention are safe in use.

In any one of three embodiments of the invention as shown and described hereinabove, the exothermic means 7, prior to use, is normally enclosed in a protective air-impervious bag 11 so that the exothermic composition 10 is prevented from contacting the open air during storage. The protective bag 11 is removed from the exothermic means when the latter is placed into the pocket.

Although not shown, the exothermic means 7 may be placed into an additional bag formed of the same material as the protective air-impervious bag 11 and the additional bag containing the exothermic means 7 may be then placed into a pocket on an apparel to be worn for example by a golfer.

While the invention has been particularly shown and described with reference to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
