Description:
REFERENCE TO RELATED APPLICATIONS 
     This is a continuation-in-part of the co-pending patent application, Ser. No. 701,858, filed July 1, 1976 now abandoned and entitled &#34;Cooled Safety Construction Helmet&#34;. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to hats and hat bands, and more particularly relates to a cooling hatband for use with an attached headwear wherein the cooling effect is achieved by the evaporative action of water which is dispensed continuously to the cooling hatband. 
     2. General Background and Prior Art 
     Many situations dictate that an individual be required to wear a hat or like headwear. For example, in the construction industry, O.S.H.A. regulations stipulate that all personnel on construction projects wear a &#34;hardhat&#34; or like helmet. This regulation makes sense, as injuries and deaths can be prevented by the hardhat protecting the wearer&#39;s head from falling objects and the like. In hot weather, as often occurs during the summer months, hardhats, helmets and like headwear can be quite uncomfortable when the temperature increases to 80° and more. 
     GENERAL DISCUSSION OF THE PRESENT INVENTION 
     The present invention provides a cooling hatband which has a structural support band attachable to a helmet, &#34;hardhat&#34;, or any desirable headwear. The support band actually abuts the the head of the wearer and supports the hat properly thereon. The support band has an adjacent, corresponding absorbent band which is capable of retaining liquid therein such as water or the like. The absorbent band is provided with a matrix of interlacing slots which register, upon mounting, with the structural band to a matrix of like interlacing openings in the structural band. Thus, air could pass through the support band and intermingle and contact with the liquid contained within the absorbent band. The absorbent band is adhered to the support band by means of a net fastener. The net fastener is a matrix of elongated thread-like members which form an interlacing arrangement, the individual thread like members being registerable with the matrix of slots of the absorbent band and the matrix of openings on the support band.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Band Construction 
     FIG. 1 illustrates the preferred embodiment of the apparatus of the present invention, designated generally by the numeral 10. The hatband 10 is comprised generally of a support band 12 which can be manufactured of any suitable supportive but pliable material such as plastic, an injection moldable plastic being an exemplary material. An absorbent band 14 which is capable of retaining liquid therein is fastened to support band 12 in a face-to-face arrangement by means of net-like fastener 16. FIG. 1 shows the three main components of cooling band 10 in a partial perspective, exploded view, but it can be seen that the three components will be easily assembled by abutting absorbent band 14 to structural band 12 and fastening it in position with fastener 16. 
     Fastener 16 is provided with a plurality of barbed male connectors 17 which register in corresponding circular openings 13 of support band 12. Fastener 16 is formed by a plurality of interlaced cables 18 which are connected at knots 19 to form an overall net as is best illustrated by FIG. 1. At its end portions, net fastener 16 is provided with a strap 20 having openings 21 therein. Strap 20 registers and connects to the end portion of support band 12 at lugs 11 to further complete a suitable connection of net fastener 16 to support band 12. Net fastener 16 could be of any strong fiber or line or like supportive material such as injection molded plastic monofilament, as is used in the manufacture of fishing line or the like. 
     Absorbent band 14 is held into face-to-face engagement with support band 12. Note that absorbent band 14 is &#34;sandwiched&#34; between net fastener 16 and support band 12, the face-to-face engagement with support band 12 being perfected when net fastener 16 is secured to support band 12 by means of male connections 17 as was discussed more fully, supra. 
     Absorbent band 14 can be of any liquid retaining and/or absorbing material such as foam , sponge, cloth, synthetic chamois or the like. Absorbent band 14 features a plurality of slots 15 therein arranged in a matrix form as is illustrated best by FIG. 1. The matrix of slots 15 increase the surface area of absorbent band 14 and thus the area upon which evaporation can occur and thus increase the cooling effect of the apparatus 10 of the present invention. It can be seen that the slots 15 of absorbent band 14 are arranged to correspond and register with the cables 18 of net fastener 16. Thus, when the connection of the three components 12, 14 and 16 is perfected, net fastener 16 will register with and occupy a position within the matrix of slots 16 in absorbent band 15. If desired, the absorbent band can be provided with backing 22 for added strength. Backing 22 and support band 12 are provided with a matrix of air vents 25 through which air can pass and contact absorbent band 14. It should be understood that the vents 25 will form a matrix which will correspond to and coincide with the matrix of slots 15 in absorbent band 14 and the matrix of cables 18 of net fastener. Thus, on assembly, air will freely pass through support band 12, backing 22 and contact the absorbent band 14 to effect evaporation of liquid contained therein and thus produce cooling effect. As long as water is retained within and present for evaporation from the absorbent band 14, the cooling hatband 10 will operate properly to cool the headwear to which it is attached (for example, a construction helmet). 
     The overall hatband 10 can be attached to the desired headwear by means of riveting or like conventional means at mounting holes 23. 
     Support band 12 can be constructed of two elongated straps 12a, 12b connected at suitable intervals by stiffeners 9, thus air can freely flow through support band 12 as is desirable. Scoop 40 can be provided at the lower portion of band 12 to channel air between straps 12a, 12b (see FIG. 2). 
     FIGS. 4-5 illustrate an alternative embodiment of head band construction used in an exemplary illustration with a construction hard hat. 
     Referring to FIG. 4, the invention comprises a safety construction helmet 110 in which water reservoir 112 is fixed interiorly in the top of the helmet. A wick 114 connects the bottom of reservoir 112 through a passageway 115 to a partially laminated headband 116 and extends between said laminations around a forehead contacting section of said headband. The interior of the helmet 110 is blackened to attract infra-red heat radiated from the head of a wearer of the helmet, and the exterior is conventionally light colored for radiating heat to the outside air. 
     Referring to FIG. 4, the water reservoir 112 is preferably moulded into the top of helmet 110 as it is manufactured. A filling opening 119, closable by a cap 120, is defined below the middle and to one side of the reservoir for introducing water or any convenient liquid therein. An interior air-bleed tube 122 extends from the top of the interior of the reservoir to a vent 123 to the exterior thereof adjacent opening 119 for preventing the formation of a vacuum in the reservoir as liquid is removed therefrom by wick 114. 
     Referring to FIGS. 5 and 6, the partially laminated headband 116 comprises a conventional helmet headband 124 of impermeable material that extends adjustably around the head of a wearer of helmet 110. Headband 124 has a plurality of holes 26 defined therethrough in a forward part 128. A headband strip 130 comprising absorbent material is fixed to headband 124 extensive with pat 128. Wick 114 is sandwiched therebetween and passes above and below holes 126 alternately in a wave pattern. 
     In use, water from the reservoir is lead down the wick to dampen the headband strip 130 from which it is evaporated and passes through holes 126. The evaporation removes heat from the headband 130 and the forehead of the helmet wearer to cool them. Heat from the rest of the wearer&#39;s head is of an infra-red nature and, attracted to the blackened interior surface of helmet 110, passes to the lighter colored exterior by conduction and radiates from said helmet exterior to the surrounding air. 
     WATER DISTRIBUTION 
     The cooling hatband 10 receives a supply of water or like suitable evaporative fluid from a supply vial of liquid contained within the headwear to which hatband 10 is connected. Such a vial (not shown) would convey fluid through a suitable duct or like conduit to liquid transfer container 30. 
     Although any evaporative fluid would suffice, a volatile chemmical is not necessary. With the improved distribution provided with the present invention, water alone will suffice as the cooling fluid. 
     Liquid transfer container 30 is formed in part on support band 12. A wick 31 extends upwardly from absorbent band 14 and is contained within container 30 when hatband 10 is assembled. The container 30 is closed and made substantially fluid tight when net fastener 16 is assembled to support band 12 sandwiching absorbent band 14 therebetween and its associated wick 31, as net 16 has container bottom 30a and container side 30b thereon. 
     As can best be seen in FIG. 3, the assembled hatband 10 features the enclosed container 30 with a conduit connection 33 thereon through which water can enter container 30 from a suitable supply vial (not shown). Thus, fluid from a supply vial can continually soak wick 31 and travel therethrough by capillary flow absorbent band 14 maintaining it in a moistened state where evaporation will occur to give the desired cooling effect to the headwear to which the present invention is attached. 
     Because many varying and different embodiments may be made within the scope of the inventive concept herein taught, and because many modifications may be made in the embodiments herein detailed in accordance with the descriptive requirements of the law, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense.
