## Title
Glove with insulation pocket

## Abstract

A glove having a heat insulating barrier is disclosed. The heat insulating barrier is removably inserted into a zippered pocket or a weblike pouch, the pocket or pouch being positioned proximate the back of a user's hand. The heat insulating barrier acts to selectively reduce heat conduction from the back side of the hand, thereby allowing the user's hand or hands to remain warm in cold environments. The ability to stack a varying number of heat insulating layers in the pouch or pocket further allows the user to selectively control the warmth of the hand as the ambient temperature fluctuates during use.

## Background
This application claims the benefit of U.S. Provisional Application 60/338,103, filed Dec. 7, 2001.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is directed to the field of apparel and, more particularly, to cold-weather hand coverings like a glove having a selectively shaped insulating barrier that is removably inserted into the hand coverings to selectively control heat conduction from the hand coverings.
2. Description of the Prior Art
It is known in the prior art to provide pouch-like pockets on the surface of gloves or mittens to provide an external source of heat for warming the hand in cold weather environments. Such prior art devices are disclosed, for example, in U.S. Pat. No. 1,970,081 (Eisendrath), in U.S. Pat. No. 4,543,671 (Monk) and in U.S. Pat. No. 4,742,579 (Dunford). Such devices, however, require periodic replenishment of the fuel or power for the external source of heat.
The glove disclosed herein obviates the need for replenishment of the fuel or power for the external heat source by employing a heat-insulating barrier—instead of a heat source—having thermal characteristics that are tailored to substantially reduce the conduction of heat away from the back side of the hand.
SUMMARY OF THE INVENTION
A glove having an insulation pocket for removable insertion of an insulating barrier is disclosed. The glove has finger portions, a thumb portion, a palm portion, a back-hand portion and a wrist portion. A first embodiment of the glove has a zippered-pocket positioned proximate the back-hand portion of the glove for removable insertion of a heat-insulating barrier. The heat insulating barrier has a first heat-insulating layer and a second heat-insulating layer that act as barriers to heat conduction from the back side of the hand.
A second embodiment of the glove has a web-like pouch that is secured to the back-hand portion of the glove for removable insertion of a similar heat-insulating barrier. Alternative embodiments of the heat-insulating barrier are contemplated and include barriers constructed of single layers rather than multiple layers and multiple barriers that are made from individual barriers that are stacked in layers, one upon the other. The ability to add and remove any number of barriers enables one to convert an otherwise cold weather glove, typically used in the cold months of winter, into a moderate weather glove that can also be used in the months of spring, thereby obviating the need to purchase or otherwise carry two sets of gloves for use in different temperature environments. A still further embodiment includes a heat-generating layer positioned adjacent the heat-insulating barrier or positioned in between any two individual heat-insulating barriers that are stacked in layers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 and 3, a glove 10 is provided that is configured to fit a human hand. The glove 10 has, generally, fingers 12, a thumb 14, a palm portion 15, a back-hand portion 16 and a wrist portion 22. A heat-insulating barrier 100 is removably inserted into a pouch means 50 that is secured to the back-hand portion 16 of the glove 10. The heat-insulating barrier 100 is secured specifically to the back-hand portion 16 of the glove 10 as it is believed that heat loss from the back-side of the hand is responsible for the fingers becoming cold in cold weather environments. For example, it is believed that heat is lost through the back of the hand while the hand grips a ski pole when skiing.
The heat-insulating barrier 100 is constructed of heat-insulating material, such as, for example, closed-cell neoprene with fleece laminated therewith, and is adapted for insertion into the pouch means 50 when the fingers of the hand are cold and for removal from the pouch means 50 when the fingers of the hand are warm or are otherwise comfortable. When the heat-insulating barrier 100 is removed from the glove 10, it may simply be placed in a pocket of the user. The heat-insulating barrier 100 thus enables one to convert an otherwise cold weather glove, typically used in the cold months of winter, into a moderate weather glove that can also be used in the months of spring, thereby obviating the need to purchase or otherwise carry two sets of gloves for use in different temperature environments.
Referring to FIGS. 2 and 4, another glove 110 is provided that is configured to fit a human hand. The glove 110 has, generally, fingers 112, a thumb 114, a palm portion 115, a back-hand portion 116 and a wrist portion 122. The heat-insulating barrier 100 is removably inserted into a pouch means 150 that is secured to the back-hand portion 116 of the glove 110. The heat-insulating barrier 100 is secured specifically to the back-hand portion 116 of the glove 110.
The heat-insulating barrier 100 is adapted for insertion into the pouch means 150 when the fingers of the hand are cold and for removal from the pouch means 150 when the user desires such as when the fingers of the hand are warm or are otherwise comfortable.
Beneficially, the heat-insulating barrier 100 does not require a power source, such as that provided through a battery or through chemical reaction, to provide heat. Rather, the heat insulating barrier 100 keeps the fingers of the hand warm by providing an extra layer, or layers, of insulation, such that the heat of the hand may be constrained from being conducted and convected to the cold air that surrounds the glove 10 (110). Various embodiments of the heat-insulating barrier are contemplated, depending on the environment in which the glove 10 (110) is to be used. A preferred embodiment of the heat-insulating barrier 100, for example, has a first heat-insulating layer 101 and a second heat-insulating layer 102. The first and second heat-insulating layers 101, 102 are joined to one another using any suitable means, such as glue or sewing thread. Alternatively, the heat-insulating barrier 100 may comprise a single heat-insulating layer or a plurality of heat-insulating layers. Alternatively still, multiple heat-insulating barriers 100 may be stacked, one upon the other, to provide the desired thermal characteristics (i.e., the desired barrier to heat conduction). In other words, more than one single heat-insulating barrier 100 may be placed into the pouch means 50 and 150, depending on the temperature and the comfort level of the user. For extreme conditions or cold-sensitive hands, one or more heat-generating layers may be used in conjunction with the heat insulating barrier or barriers.
Referring now to the first embodiment, as illustrated in FIG. 1, the fingers 12, thumb 14, the palm portion 15 and back-hand portion 16 and the wrist portion are constructed from heat-insulating and water resistant materials that comprise the upper surface 18 and the lower surface 20 of the glove 10. For example, the first embodiment of the glove 10 has an upper surface 18 that is comprised of an inner layer 30 and an outer layer 40. The outer layer 40 is preferably constructed from a water resistant material while the inner layer 30 is constructed of a heat-insulating material. In a similar fashion, the glove 10 has a lower surface 20 that is constructed of an inner layer (not referenced) and an outer layer (not referenced). The outer layer of the lower surface 20 is also, preferably, constructed of a water resistant material and may have a roughened surface texture to facilitate the grasping of objects in a snowy or otherwise cold and wet environment. The inner layer of the lower surface 20 is preferably constructed using a heat-insulating material.
Referring still to FIG. 1, the pouch means 50 is constructed such that a zipper 52 is secured to an opening 60 that is cut into the outer layer 40 of the upper surface 18. The zipper 52 is illustrated as extending laterally across the glove 10 proximate the wrist portion 22, although the zipper could just as readily be configured to extend laterally across the glove 10 proximate the base 11 of the finger portions 12. Although not illustrated, it is further contemplated that the zipper may extend longitudinally 13 along the back-hand portion 16 of the glove 10, with one end of the zipper starting proximate the wrist portion 22 of the glove 10 and the other end of the zipper terminating proximate the base 11 of the finger portions 12 of the glove 10. Preferably, the longitudinally extending zipper (not shown) will be positioned on one side of the back-hand portion 16 of the glove 10—i.e., the thumb side 23 or the little finger side 25.
The opening 60 provides access to the space of the glove 10 between the inner layer 30 and the outer layer 40. The space extends the length and width of the back-hand portion 16. A perforated pouch 70 extends into the opening 60 and also covers the back-hand portion 16 of the glove 10. The perforated pouch 70 is sized and shaped to receive the heat-insulating barrier 100. When the heat-insulating barrier 100 is fully inserted into the glove 10, the perforated pouch 70 will restrain the barrier 100 from movement between the inner layer 30 and the outer layer 40 and, thereby, ensure that the barrier 100 will remain positioned about the back-hand portion 16 of the glove 10. The pouch 70 enables easy insertion and removal of the heat-insulating barrier 100 which, in turn, enables quick and efficient conversion between configuration for cold and warmer (or not so cold) conditions simply by adding or removing barriers 100 as needed. A plurality of barriers 100 may be easily carried by a user—e.g., in the user's pocket—to enable conversion between cold and less cold environments as the day progresses from morning to night. If desired, one or more heat-generating layers may be positioned adjacent any one or more of the heat insulating barriers 100 in the pocket 70.
Various sizes and shapes of the perforated pouch 70 are contemplated to coincide with various sizes and shapes of the heat-insulating barrier 100. For example, a heat-insulating barrier 100 having a width 105 (see FIG. 5) from about three inches to about four inches, a length 106 from about three inches to about five inches and a thickness 107 from about one-sixteenth of an inch to about one-fourth of an inch are contemplated, with preferable dimensions having a width 105, length 106 and thickness 107 equal to about three and one-half inches, about four inches and about one-eight of an inch, respectively. Referring to FIG. 3, a heat-insulating barrier 100 having the above preferred dimensions is illustrated being partially inserted into the perforated pouch 70.
Both the upper surface layer 18 and the lower surface layer 20 of the glove 10 have peripheries 19, 21 that are cut into the pattern for a human hand. Thus, the glove 10 may be fashioned by securing the upper surface layer 18 to the lower surface layer 20 at the peripheries 19, 21 using any means, such as, for example, by sewing. Further, side panels 80 may be positioned between the upper surface layer 18 and the lower surface layer 20 to form the fingers 12 as shown and provide the glove 10 with a better fit to the fingers of the hand. In a similar fashion, the thumb portion 14 may be constructed independently of the upper surface layer 18 and the lower surface layer 20 and secured independently to, for example, the lower surface layers to provide a better fit for the thumb of the hand. And as is well-known in the art, a strap 85 and a wrist cinch 87 may be secured to the glove 10 to provide the glove 10 with a secure and snow-tight fit about the wrist of a user.
A second embodiment of the glove 110 illustrated in FIG. 2 has an upper surface 118 and a lower surface 120 that are both constructed from a single layer 130. The single layer 130 is preferably constructed from a light-weight, heat-insulating material, such that the glove 110 may be used, for example, as a liner to an outer glove shell (not illustrated). Alternatively, the glove 110 may be used in a cold environment where finger dexterity is required.
Referring still to FIG. 2, the pouch means 150 is constructed such that a flexible, web-like material forms a web-like pouch 152 that is secured to the upper surface 118 of the glove 110. The web-like pouch 152 extends substantially over the back-hand portion 116 of the glove 110 and has a first peripheral portion 154 (A–C) and a second peripheral portion 156. The first peripheral portion 154 (A–C) is secured to the upper surface 118 of the glove 110 through any suitable means, such as, for example, by sewing. The second peripheral portion 156 is left unsecured and provides an opening 160 through which the heat-insulating barrier 100 may be removably inserted. The first peripheral portion 154 and the second peripheral portion 156 are sized and shaped so that the heat-insulating barrier 100 is securely positioned over the back-hand portion 116 of the glove 110. When the heat-insulating barrier 100 is fully inserted into the glove 110, the web-like pouch 152 will restrain the barrier 100 from movement over the upper surface 118 of the glove 110 and, thereby, ensure that the heat-insulating barrier 100 will remain positioned in the back-hand portion 116 of the glove 110.
Various sizes and shapes of the peripheral portions 154 (A–C), 156 are contemplated to coincide with various sizes and shapes of the heat-insulating barrier 100. For example, a heat-insulating barrier 100 having a width 105 from about three inches to about four inches, a length 106 from about three inches to about five inches and a thickness 107 from about one-sixteenth of an inch to about one-fourth of an inch are contemplated, with preferable dimensions having a width 105, length 106 and thickness 107 equal to about three and one-half inches, about four inches and about one-eight of an inch, respectively. Referring to FIG. 4, a heat-insulating barrier 100 having the above preferred dimensions is illustrated being partially inserted into the web-like pouch 152.
The single-layers 130 of the upper surface 118 and the lower surface 120 of the glove 110 have a peripheries 119, 121 that are cut into the shape of a human hand. Thus, the glove 110 may be fashioned by securing the single layers 130 of the upper surface 118 and the lower surface 120 at the peripheries 119, 121 using any traditional means, such as, for example, by sewing. Further, side panels 180 may be incorporated into the finger portions 112 between the single-layers 130 of the upper surface 118 and the lower surface 120 of the glove 110 to provide the glove 110 with a better fit to the fingers of the hand. In a similar fashion, the thumb portion 114 may be constructed independently of the single-layers 130 of the upper surface 118 and the lower surface 120 of the glove 110 and secured independently to, for example, the lower surface 120 to provide a better fit for the thumb of the hand. A tightly knit wrist portion 122 is sewn onto the glove 110 proximate the palm portion 115 and the back-hand portion 116 to give the glove 110 a tight fit about the wrist of a user.
Various other modes for carrying out the invention are contemplated as being within the scope of the following claims particularly pointing out and distinctly claiming the subject matter which is regarded as the invention.
