1. Field of the Invention
The present invention relates generally to hand coverings and more particularly to a hand covering with internal thermal tubes.
2. Discussion of the Related Art
In cold weather, it is often desirable to keep one's hands warm by wearing gloves or similar hand coverings. A concern arises when, during extreme temperature conditions, it is difficult to maintain ones hands at a comfortable temperature regardless of whether or not one is wearing such hand coverings. Accordingly, hand coverings have been provided that allow a user to warm their hands beyond the temperature which is provided by simply wearing the hand covering.
Hand coverings have been provided that allow the wearer to introduce heat into the interior of the hand covering. Such hand coverings typically allow the heat to dissipate throughout the entire interior chamber of the hand covering. A problem with such hard coverings is that the heat dissipates quickly and the extremities (i.e., the fingertips) often do not receive the warm air and therefore remain at an uncomfortable, cold temperature. This is a concern because extremities are typically the first part of the body to get cold and are also the most difficult to warm up once they have become cold.
Other hand coverings have been provided that allow air to be ventilated through the chamber of the hand covering in which the hand is placed to allow for air flow and greater comfort for the wearer.
What is needed is an improved hand covering that communicates warm air to the extremities of the wearer's hand without dissipation of the warm air between an inlet and an outlet and allows for adequate ventilation.
A hand covering includes a hand receiving portion that is closed at a first end and that defines an opening at a second end. A cover is coupled to the hand receiving portion and an air distribution device is disposed between the cover and the hand receiving portion. The air distribution device has an inlet and outlet that are positioned in a spaced apart relationship.
In another embodiment of the present invention, the hand covering includes a first layer, a second layer coupled to the first layer, multiple channeling members defined between the first and second layers and an air intake configured to direct air to each of the inlets of the channeling members. Each channeling member includes an inlet and is configured to communicate air to its own outlet.
In a further embodiment of the present invention, a method of manufacturing a hand covering is provided. The method includes coupling a first membrane to a second membrane to form an air distribution device. The air distribution device is positioned adjacent a first layer of the hand covering. A second layer of the hand covering is then positioned adjacent the first layer such that the air distribution device is substantially encapsulated between the first and second layer. An air conduit is coupled adjacent to an inlet of the air distribution device.
These and other aspects of the present invention will become apparent from the following drawings and description.
The present invention is described with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or functionally similar elements.
A hand covering is configured to distribute air from an inlet to at least one outlet that is spaced apart from the inlet. The outlet is spaced apart from the inlet such that air is distributed to the extremities of the hand covering without dissipating throughout the hand covering.
A second layer or cover 120 is coupled to the hand receiving portion 110 and an air distribution device 150 (not shown in
The air distribution device 150 is configured to communicate air from an inlet 151 to at least one outlet 159 (see FIG. 4). The inlet 151 and outlet 159 are positioned in a spaced apart relation such that the air introduced into the inlet travels over a length before exiting at the outlet 159. As discussed above, the air is to be distributed through the hand covering such that the extremities of the user are contacted by exhausted air while minimizing the dissipation of heat throughout the other portions of the hand covering.
The temperature and pressure of the air at the inlet 151 can be substantially the same as the temperature and pressure of the air at the outlet 159. Depending upon the relative sizes of the inlet 151 and outlet 159, and the size of the channels through which the air flows (described in detail below) the pressure differential between the inlet 151 and outlet 159 may vary (i.e., be greater or lesser pressure at the outlet than at the inlet).
The air distribution device 150 is disposed within the hand covering 100 such that the outlet 159 is positioned proximate the closed end 112 of the hand receiving portion 110. Accordingly, the air will be directed to the extremities of the user as desired.
An air conduit or air intake 180 is provided to facilitate the introduction of air into the air distribution device 150. In the illustrated embodiment, the air conduit 180 is configured as a mouthpiece into which the user can blow to introduce air into the air distribution device 150. As will be appreciated, the air conduit 180 may take many other forms as illustrated in
The cover 120 defines an opening (not illustrated) that is positioned in registry with the inlet 151 of the air distribution device 150. The air conduit 180 is in gaseous communication with the inlet and can be positioned in registry with the opening in the cover 120. The air conduit can be coupled directly to the cover 120, or alternatively, coupled directly to the air distribution device 150. Alternatively, there may be no air conduit 180 and there may simply be an opening in the cover 120 of the hand covering 100. In a further alternative embodiment, there is no opening in the cover 120 and the user provides air through the cover to an air conduit.

As shown in
In the illustrated embodiment, an air conduit 380 is coupled to the first membrane 353 adjacent to, and in registry with, the inlet 351.
A layer of material 360 is disposed between the first membrane 353 and second membrane 355 within the air passage. The material 360 that is located in the air passage defined by the two membranes 353, 355 can serve many purposes. The material 360 is configured to maintain the air passage open (i.e., prevent the two membranes from sticking together). The material 360 also can serve as a wicking material or desiccant to aid in the drying and distribution of moisture out of the air distribution device. The material 360 can be manufactured, for example, from foam or may be an interwoven porous material. The material 360 in addition to providing a moisture barrier and acting as a wicking material, may also have heat retaining qualities. The material 360 allows only minor dissipation of the heat of the air provided at the inlet, and allows the air to pass through the channeling members 356 at a substantially constant temperature.
Returning to the hand covering 100 of
An alternative embodiment of an air distribution device 250 for use with an alternative hand covering 200 having an open end 214 and a closed end 212 is illustrated in FIG. 5. In this embodiment the air distribution device 250 includes an air conduit or air intake 280 that is coupled to the air distribution device 250 adjacent the inlet 251. The air outlets 259 are located adjacent the closed end 212 of the hand covering 200 and are defined by the second membrane (not visible in FIG. 5). As is apparent, two) hanneling members 256 are coupled to an air chamber 257. One of the channeling members 256 includes multiple outlets 259 while the other channeling member 256 includes at single outlet 259. Alternatively, both of the channeling members 256 could include a plurality of outlets or a single outlet 259.

As illustrated in
The first and second membrane 653, 654 may be coupled together in a variety of configurations to form various outlets. For example, channeling member 655 illustrates an embodiment in which the first and second membranes are coupled together such that they are both arcuate in cross section, and define an opening or air passage 665, to inhibit the collapsing of the channeling member 655.
The first and second membrane 653, 654 that comprise channeling member 656 are configured such that the first membrane 653 is positioned in an arcuate fashion above the second membrane 654 which is taut in configuration such that the first membrane 653 does not collapse thereby closing an opening or air passage 666, inhibiting air flow through the channeling member 656.
Channeling member 657 includes a layer of material 660 disposed therein to prevent the first membrane 653 from collapsing onto the second membrane 654 thereby closing an opening or air passage 667, inhibiting the flow of air through the channeling member 657 as previously described. As will be appreciated, other configurations of the channeling members of the air distribution device that allow the passage of air, but resist the collapsing of the channeling member are contemplated by the present invention.
Several alternative embodiments of outlets of the air distribution device are illustrated in FIG. 16. For example, outlet 765 may include openings defined on the second membrane of the air distribution device. The outlets may be various shapes and sizes and may be positioned along the length of a channeling member 766 of the air distribution device as illustrated by outlets 761, 762, 763, and 764. Alternatively, the outlet may be a single opening 759 defined proximate the end of the second membrane as discussed above. The outlet may also be defined at the end of the channeling member as illustrated by outlet 760.
A further embodiment of an air conduit 1280 is illustrated in
Any of the alternative air conduits described with respect to
The hand covering 2700 includes a hand receiving portion 2710 having a first end 2712 and a second end 2714. An air distribution device 2750 is coupled to the hand receiving portion 2710 and includes an inlet 2751 and outlets 2759. An air chamber 2757 is located adjacent the inlet 2751. The air distribution device includes air channels 2756 that extend between the air chamber 2757 and the outlets 2759.
The air distribution device 2750 may be constructed from two membranes as described above or, alternatively, may include a single membrane coupled adjacent to one side of the hand receiving portion 2710.
In use, when the hand covering 2700 is used as a liner to be inserted into a glove or a mitten, the first end 2712 of the hand covering 2750 can be positioned adjacent to the closed end of the glove or mitten and the second end 2714 can be positioned adjacent to the open end of the glove or mitten.
An air distribution device 2850 is coupled to the hand receiving portion 2810 and includes an inlet 2851, and multiple outlets 2859 spaced apart from the inlet 2851. The air distribution device 2851 is configured to communicate air from the inlet 2851 to the multiple outlets 2859 through multiple air channels 2856 such that the temperature and pressure of the air at the inlet 2851 are substantially the same as the temperature and pressure at the outlets 2859. Alternatively, the pressure of the air at the inlet 2851 may be different than the pressure of the air at the multiple outlets 2859. The air distribution device 2850 can include an air chamber 2857 located between the inlet 2851 and the air channels 2856.
The inlet 2851 of the air distribution device 2850 is substantially coplanar with the opening defined at the second end 2814 of the hand receiving portion 2810. The outlets 2850 are each substantially coplanar with an opening defined at the first end 2812 of the hand receiving portion 2810. In this manner, air that is distributed through the air distribution device 2850 is exhausted to the portion of the user's hand that protrudes through the openings defined in the first end 2812 of the hand receiving portion 2810. Because the air distribution device 2850 does not dissipate a substantial amount of heat along the length of the air passages as previously described, the amount heat exhausted at the outlet is maximized.
The air distribution device may include two membranes, as described above, that define the inlet 2851, the outlets 2859 and the air passages 2856. There may be a material disposed between the two membranes that has the moisture reducing and/or heat retaining qualities described above.
In alternative embodiments, the air distribution device may include a single membrane coupled adjacent to one side of the hand receiving portion 2810. In such an embodiment, the membrane and the hand receiving portion together define the inlet 2851, the outlets 2859 and the air passages 2856. There may be material disposed between the membrane and the hand receiving portion as previously described.
In use, the hand covering 2800 may be used as a liner that is inserted into another hand covering such as a glove or a mitten.
Each group of three figures represents a top, side and front view of the illustrated embodiment. For example,
The hand covering can be manufactured by coupling the first membrane of the air distribution device to the second membrane of the air distribution device to provide the air chamber and air channeling members as described above. The two membranes can be coupled together, for example, by a radio frequency weld adjacent to an edge of each of the first and second membranes, or alternatively, by melting or heat welding the two membranes together. The completed air distribution device is then positioned adjacent the first layer or hand receiving portion of the hand covering and then the second layer or cover is then positioned adjacent the hand receiving portion such that the air distribution device is substantially encapsulated between the first layer and second layer.
The first layer and second layer of the hand covering are then coupled together by, for example, using a single seam. In the embodiment described above in which the air distribution device 450 includes tabs or securing elements 470, 475, the tabs may be sewn along the same seam, or alternatively may be separately attached to the first layer or hand receiving portion. In embodiments in which the hand covering includes an air conduit, the air conduit is coupled adjacent to the inlet of the air distribution device. The air conduit may be coupled directly to the air distribution device, may be coupled to the second layer or cover, or may be coupled to both the air distribution device and the cover.
In embodiments of the invention that include a layer of material between the first and second membrane of the air distribution device, the material is positioned between the two membranes before they are secured together as described above. The material may be positioned throughout the entire air distribution device, or may alternatively be positioned throughout only a portion of the air distribution device.
In use, air is distributed to a closed end of the hand covering 100 when pressurized air is received from an air source, such as, for example, a user's mouth. An alternative source of air could be a conventional blow dryer 111 as illustrated in FIG. 41. The pressurized air is then channeled to an air inlet that is defined by the first membrane of the air distribution device and then channeled to the air outlet adjacent to the closed end of the hand covering. The volume of air provided at the inlet is provided at an inlet temperature greater than an ambient temperature (i.e., the user's hand temperature) and is channeled through the air distribution device to the air outlet adjacent the closed end of the hand covering. Substantially all of the volume of air is channeled to the air outlet at a temperature substantially equal to the inlet temperature.
