1. Field of the Invention
The present invention relates to devices and methods for keeping a person warm, and, more particularly, to such devices and methods for keeping hands warm.
2. Description of Related Art
In cold environments hand covers are frequently used to cover the hands to keep them warm. For example common hand covers are glove and mittens. For those performing complicated tasks, however, these items of apparel can cause a loss in digital dexterity, which can be deleterious in situations wherein fine motor control of the hands and fingers is required. Attempts to solve this problem have been performed by creating fingerless gloves and larger gloves or mittens that encompass a held item, such as a tennis racquet grip, as well as the hand. Another solution is a “hand warmer,” which includes a disposable or reusable glove that contains components the mixing of which cause an exothermic reaction and emit heat thereby. However, the person is still required to wear a glove to keep his/her hands warm.
Among those affected by this problem are athletes such as football players, construction workers, repairmen, emergency medical personnel, and photographers, as well as any other people who must operate in cold environments for extended periods and require feeling or sensitivity while handling their respective implements.
Therefore, it would be beneficial to provide a device and method for warming the hands that does not inhibit manual and digital dexterity.
The present invention is directed to a hand warmer device and, associated methods that address the above-discussed problems of maintaining hand warmer while not inhibiting dexterity in the wearer. The device comprises a flexible sheet having an adhesive portion on an inner face thereof. The sheet is formed generally in the shape of a hand in two dimensions. Affixed to an outer face of the sheet is an activatable heating element continuing a composition comprising materials the mixing of which cruses an exothermic reaction.
In use, a person can affix the sheet to a top of the hand by adhering the inner face thereto. The heating element composition can be activated by flexing the fingers, causing a mixing of the composition materials, and thereby the emission of heat. The heating device can thus keep the hand and fingers warm for some number of hours while leaving the palms and insides of the fingers free to perform a desired task.
The features that characterize the invention, both as to organization and method of operation, together with further objects and advantages thereof, will re better understood from the following description used in conjunction with the accompanying drawing. It is to be expressly understood that the drawing is for the purpose of illustration and description and is not intended as a definition of the limits of the invention. These and other objects attained, and advantages offered, by the present invention will become more fully apparent as the description that now follows is read in conjunction with the accompanying drawing.
The advantages and features of the present invention will become better understood with reference to the following detailed description and claims taken in conjunction with the accompanying drawings, wherein like elements are identified with like symbols, and in which:
Like reference numerals refer to like parts throughout the description of several views of the drawings.
The present invention relates to devices and methods for keeping a person warm, and, more particularly, to such devices and methods for keeping hands warm. The present invention provides a hand warming device to cover the top of a user's hand while still allowing full dexterity and sensation. The hand warming device includes an adhesive flexible sheet with multiple heating elements. The heating elements are positioned above the topsides of the palm, and fingers. When the user flexes and moves their hand and fingers a composition of materials within the heating elements react with each other to create an exothermic reaction, therefore warming the user's hands while still allowing use and sensation of the hand while performing other tasks.
Turning now descriptively to the drawings, referring to
Referring now to
During use, a person may affix the hand warming device 10 to a top 26 of the hand 27 and top of the fingers 29 by adhering the flexible sheet's inner face 13 thereto. The elongated heating elements 23, 24 may be activated by flexing the fingers 29 and the rectangular heating element 24 by moving the hand 27, breaking the barrier 20 between the envelope compartments 18, 19 causing a mixing of the composition materials, and thereby the emission of heat. The heating element device 10 thus keeps the hand 27 and fingers 29 warm for some number of hours while leaving the palm and insides of the fingers 29 free to perform a desired task.
