BACKGROUND OF THE INVENTION

(1) Field of the Invention
The inventive concept presented herein is concerned with devices used to provide comfortable cooling to the human body, particularly in those situations involving moderate or greater physical exertion. Common methods used to provide cooling to persons functioning in hot environments include large-sized ambient air-generating fans, misting sprays, refrigerating apparatuses, and others. These methods either direct cool airflow toward the person affected by the heat, or provide the cooling effect of evaporating, water. Generally all of the previously mentioned solutions are too bulky or heavy to function effectively for persons who are constantly on the move or in an outdoor environment where such devices are impracticable or unwieldy.

BRIEF SUMMARY OF THE INVENTION

The inventive concept, entitled, “Keep it Cool,” is an apparatus comprising a. headgear unit and a control unit, which cooperatively provide for the flow of air through the interior of the headgear. The headgear is effective in preventing or reducing perspiration in the hair and/or scalps of persons who are active due to physical exercise, working in the sun, outdoor recreation, or who may suffer hormonal issues. There is an endless list of activities engaged in by people wherein a scalp/hair cooling mechanism such as disclosed, would provide a certain amount of comfort or relief from overheated body temperatures.
The device may be battery powered or driven by common ac current from a wall outlet The headgear portion of the device has a flexible comb-like arrangement, wherein the teeth of the comb are constructed with internal conduits allowing the passage of air through the interior of the teeth. The air is expelled through spaced openings of the teeth. The overall design of the headgear comprises a semi-circular contour to comfortably fit over the shape of a human scalp. A distribution tube connects the headgear teeth with a compact control unit, which unit may be fastened to the wearer's clothing. Airflow is initiated by a miniature fan within the control unit, and the airflow is then routed through the distribution tube and into the conduits of the headgear teeth.
The apparatus is adaptable to outfitting with a cool un within the control unit so as to substantially reduce the temperature of air that is propelled into the conduits of the teeth. An embodiment of the device may be equipped with control mechanisms to regulate both the volume of airflow and the temperature of the air being circulated through the conduits. The headgear and teeth are made from a suitable elastomeric material. The headgear is easily bent or flexed in order to fit the contour oldie average shaped head.

DETAILED DESCRIPTION OF THE INVENTION

The objects, features, and advantages of the concept presented in this application are more readily understood when referring to the accompanying drawings. The drawings, totaling five figures, show the basic components and functions of embodiments and/or methods of use. In the several figures, like reference numbers are used in each figure to correspond to the same component as may be depicted in other figures.
The discussion of the inventive concept will be initiated with FIG. 1, which illustrates the entire device, including the control unit 1, the distribution tube 2, and the headgear 22. The embodiment shown in FIG. 1 comprises a control unit 1 having a temperature indicator 5 and a rotary on-off switch 4. The distribution tube 2 serves to confine and direct air currents driven from a fan 14 (not shown) internal to the control unit 1 into the headgear 22. The headgear 22 comprises a flexible comb 20 having a plurality of windings which form inner tips or teeth 18 and outer tips or spines 19. The flexible comb 20 may be comprised of any of a variety of materials having elastomeric characteristics, including, but not limited to plastic, fiberglass, rubber, silicon, vinyl, PCV, and the like.
FIG. 2 shows the manner in which the headgear 22 may be worn by a user. The flexible comb 20 is shown as having its entire length entwined within strands of hair of the user. The connector 3 is affixed to the distribution tube 2 which itself extends from the control unit 1. The control unit 1 may be affixed to an item of clothing 24 of the wearer, as shown.
FIG. 3 depicts a view of the control unit 1 of the device after removing a form-fitting casing access door. The access door of the casing 6 is constructed of the same perimetral dimensions as the overall control unit 1. As can be seen, airflow for the device is provided by operation of a mini-fan 14, which is connected by a drive shaft 13 to a small electric motor 12. In the embodiment shown, the electric motor 12 is powered by a small battery 8, preferably of 9-volt capacity. For on-off switching, there is a switch terminal 26 affixed to the electric motor 12, which when the casing access door is closed, makes contact with the exterior control unit 1 switch 4. The battery It is held in position by a dual-pronged mounting clip 7. The positive terminal 9 and the negative terminal 10 of the battery 8 conduct the direct current of the battery 8 through a lead wire 11 directly to the electric motor 12
In other embodiments, electrical power for the device may be alternatively supplied by an adapter which receives household alternating current and converts the current, into suitable direct current for the electric motor 12.
Upon receiving adequate electric current, the electric motor 12 powers the fan 14 which draws ambient air from a filtered, and restricted intake 15 into a small receiving plenum 16. The plenum 16 is directly connected to a distribution tube 2 by means of a connector at the first end 27 of the distribution tube 2. The distribution tube 2 then leads to the device's headgear 22 where an airtight connection is made to a connector 3 corresponding to the location of the initial end of device's conduits 21, 23. The entirety of the control unit 1 is enclosed in a semi-rigid casing 6. The mounting clip 7 is affixed to the inner surface of the casing 6 to provide a secure fit for the battery 8.
In viewing FIG. 4, there is observed an enlarged view of the flexible comb 20 section of the headgear 22. The undulating structure of the comb 20 features a plurality of teeth 18 which serve the purpose of engaging the hair or a wearer when the device is in use. At the opposite end of each tooth 18 is an arcuate spine 19 which connects successive teeth. The connected series of teeth 18 and spines 19 form the entirety of the flexible comb 20 segment of the headgear 22. Also shown in FIG. 4 is a plurality of outlets 17, one within each of the teeth 18 shown.
In turning to FIG. 4A, as determined by the section line 4A-4A, there is shown a cross-sectional view of a typical peak of one tooth 18 of the headgear 22, including a conduit bend 25 as determined by the section line 4A-4A of FIG. 4.
In FIG. 5, there is depicted the hidden structure and path of the downflow conduits 21, and upflow conduits 23 internal to the teeth 18 of the headgear. Typical outlets 17 are also shown. FIG. 4 and FIG. 5 are drawn with the convention of airflow being propelled, by the control unit 1 fan 14, from the left side of each figure to the right side of the figure. Each outlet 17 allows a certain volume of air currents to he expelled from the downflow conduit 21, just after the air reaches the conduit bend 25. The expelled air then flows proximate the scalp of the wearer of the headgear 22. All un-expelled air then continues to flow through the upflow conduit 23 within the spine 19 and to the next successive outlet 17.
The control unit 1 is adaptable to outfitting a small compartment within the plenum 16, said compartment suitable for containing a refrigerant, such as dry ice, frozen gel polymers, or the like. In this manner, as the fan 14 propels air from the plenum 16, the distribution tube 2 receives an at a substantially lower temperature than the intaken ambient air. A different embodiment of the deice may be equipped with a variable-speed on-off switch so as to gain control over the volume of air propelled into the conduits 21, 23 of the device. Other embodiments may further be equipped with a temperature gauge to indicate the temperature of air entering the distribution tube 2. The headgear 22, teeth 18, and spines 19 are made from a suitable elastomeric material. The comb 20 is easily bent or flexed in order to fit the contour of the average person's head.
