## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority of Chinese application no. 200610001137.4, filed on Jan. 13, 2006.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a warming glove, and more particularly to a durable and stretchable warming glove.
2. Description of the Related Art
Gloves can be classified into two categories: one for protecting the hands of users from being injured while at work and the other for keeping the hands of users warm. The conventional warming glove, as shown in FIG. 1, comprises a glove body 1 having a thumb portion 6, finger portions 7, a palm portion 10, in which an electrical heating plate 11 is provided, and a wrist portion 12, on which two terminals 3, 4 are provided for electrical connection with a battery (not shown in FIG. 1) and for electrical connection to the electric heating plate 11 through a conductor 5. Thus, when a battery is electrically connected to the terminals 3, 4, the heating plate 11 generates heat, as a result of which the hand of the user can be kept warm. However, such a conventional glove has some deficiencies. For example, since the heat is generated only from the heating plate 11, considerable time is spent for transferring heat from the location of the heating plate 11 to the entire glove body 1. Thus, the user always encounters a problem in that heat is distributed unevenly. On the other hand, gloves are generally made of a stretchable and contractible fabric so as to provide elasticity and softness that will comfort users during work or exercise. However, the heating plate 11 provided in the aforesaid conventional glove is rigid and thus, can cause discomfort to the user. Moreover, the heating plate 11 is liable to displace upon frequent stretching or pulling of the glove. At the worst, the heating plate 11 can even break and lose its heat generating properties. Further improvements in the warming glove are thus desirable.
SUMMARY OF THE INVENTION
Therefore, an object of the present invention is to provide a warming glove that provides good wearability while still incorporating a heating element durable to endure frequent stretching and bending of the glove.
Another object of the present invention is to provide a more durable warming glove compared to the prior art.
Accordingly, the present invention provides a warming glove which comprises a glove body including a palm side sheet, a back side sheet, and a connection member interconnecting lateral ends of the palm and back side sheets. The glove body has a wrist portion, a palm portion, a thumb portion, and finger portions. The lateral ends include lateral sides of the wrist, palm, thumb and finger portions. The connection member extends continuously and laterally from the lateral sides of the wrist portion to the lateral sides of the palm portion and from the lateral sides of the palm portion to the lateral sides of the thumb and finger portions. The warming glove further comprises a heating element disposed in and extending along the connection member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in FIGS. 2, 3 and 4, the preferred embodiment of a warming glove of this invention comprises a glove body 2 including a palm side sheet 21, a back side sheet 22, and a connection member 3 sewn to and interconnecting lateral ends 211, 221 of the palm and back side sheets 21, 22. The glove body 2 has a wrist portion 24, a palm portion 25, a thumb portion 26, and finger portions 27. The lateral ends 211, 221 of the palm and back side sheets 21, 22 include two lateral sides 241 of the wrist portion 24, two lateral sides 251 of the palm portion 25, and lateral sides 261, 271 of the thumb portion 26 and the finger portions 27. The connection member 3 extends continuously and laterally from the two lateral sides 241 of the wrist portion 24 to the two lateral sides 251 of the palm portion 25 and from the two lateral sides 251 of the palm portion 25 to the lateral sides 261, 271 of the thumb and finger portions 26, 27.
In this embodiment, the connection member 3 has an elongated fabric sleeve 23 that is made by sewing together two fabric strips 231. Each fabric strip 231 has two opposite longitudinal marginal ends 2310 that are sewn respectively to the marginal ends 2310 of the other fabric strips 231. The marginal ends 2310 of the fabric strip 231 are also sewn respectively to the lateral ends 211, 221 of the palm side and back side sheets 21, 22. While the connection member 3 in this embodiment is the fabric sleeve 23 made by sewing together two fabric strips 231, it is contemplated that the fabric sleeve 23 could be made from a knitted tubular fabric, or a single fabric sheet.
The heating element 4 is preferably disposed loosely within a space 30 inside the fabric sleeve 23. The heating element 4 extends continuously along the connection member 3 from the wrist portion 24 to the thumb and finger portions 26, 27 through the palm portion 25. The heating element 4 may be a metal conductor or a carbon conductor. In this embodiment, the heating element 4 is a carbon conductor 40 that is loosely received within the fabric sleeve 23 so that the carbon conductor 40 is freely movable relative to the fabric sleeve 23. Preferably, the heating element 4 is not fastened to the fabric sleeve 23 by any means, such as sewing or bonding.
The carbon conductor 40 has two opposite ends 401, 402 extending respectively to the two lateral sides 241 of the wrist portion 24. The ends 401, 402 are connected respectively two connecting conductors 41, 42 which are in turn connected respectively to positive and negative terminals 14, 15 disposed at the open end 20 of the wrist portion 24 for electrical connection to a battery (not shown). The carbon conductor 40 includes a plurality of carbon filaments 403 that extend from the end 401 to the end 402 of the carbon conductor 40. The carbon filaments 403 are separated from each other between the ends 401, 402, and are bundled using tying elements, such as sleeves (not shown), at the ends 401, 402. When the carbon conductor 40 generates heat along the connection member 3, the heat can reach thumb and fingers of the user at the same time. Therefore, quick and uniform heating can be achieved.
It is preferable that the palm and back side sheets 21, 22 are stretchable and contractible along a first direction (I) parallel to a line that extends from the wrist portion 24 to the finger portions 27 and a second direction (II) perpendicular to the first direction (I). It is also preferable that the connection member 3 is stretchable and contractible in the first direction (I) and a third direction (III) perpendicular to the first and second directions (I) and (II).
In view of the aforesaid, the warming glove according to the present invention has the following advantages:

    1. Since the palm and back side sheets 21, 22 are stretchable and contractible along the first direction (I) and the second direction (II), and since the connection member 3 is stretchable and contractible along the first direction (I) and the third direction (III), the warming glove of the present invention can be perfectly fitted to the hand of the user when worn.
    2. The provision of the heating element 4 does not affect adversely the wearability and appearance of the warming glove since the heating element 4 is loosely disposed within the space 30 inside the fabric sleeve 23 of the connection member 3.
    3. Because the carbon conductor 40 is not fixed to the connection member 3, even when the palm and back side sheets 21, 22 and the connection member 3 are stretched excessively in the second and third directions (II) and (III), the stretching thereof will not affect and break the carbon conductor 40. In addition, because the connection member 3 has sufficient resistance to pulling forces, when the user takes the glove off by pulling at the finger portions 27 of the warming glove in the first direction (I), the carbon conductor 40 will likewise not break.
    4. The carbon conductor 40 contained within the warming glove does not break easily when the warming glove is folded frequently. Thus, the warming glove is durable.


While the present invention has been described in connection with what is considered the most practical and preferred embodiment(s), it is understood that this invention is not limited to the disclosed embodiment(s) but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
