    [1" class="description-paragraph] COMBINATION HAIR DRYER COVER AND HEAD SHIELD FIELD OF USEThe invention relates to a device for use in a beauty salon for drying and setting hair, and more particularly, to a device that directs heat from the hair dryer onto the patron's hair in an energy efficient manner. BACKGROUND OF THE INVENTIONThe conventional hood hair dryer is outdated for many hair drying applications.Instead, it is being used primarily as a means to direct heat energy to the hair - in other words, to warm the hair and not necessarily to dry it. When heat is applied with a hair conditioner, hair coloring, or a perm, the styling and conditioning of the hair is enhanced.While head covers have been used to cover the hair of the patron, these head covers are generally used to enable an even distribution of heat to be applied to all of the hair that is to be treated. Such covers have substantial heat losses and can cause substantial discomfort to the wearer.What is needed is a device that will minimize the amount of time needed to heat the patron's hair while not wasting heat energy; that will be comfortable to the patron and will reduce the noise level during use; that is adjustable for various head sizes and heights; that is readily disposable thereby preventing the spread of disease from patron to patron; and that is easy to use and will not dry the patron's hair.What is needed is a device that is inexpensive to make, that is made from conventional materials, that is disposable after use by each patron for sanitation purposes, and that will enable the hair dryer (heat source) cover to be separated from the head shield (heat shield) to enable separate deployment of either. SUMMARY OF THE INVENTIONThe combination hair dryer cover and head shield of the present invention prevents the hair from drying out when the perm, hair color, or conditioner is being used on the hair; keeps hair chemicals contained under the cap not on the dryer; keeps the heat on the head and away from the ears, neck and face;reduces the noise level under the dryer; is energy efficient and requires less processing time; is constructed of durable and reliable materials; is adjustable to fit all head sizes; decreases hair drying time; is inexpensive to manufacture with regard to both labor and materials; and is disposable.In the broadest sense, the combination source cover (hair dryer cover) and heat shield (head shield) apparatus of the present invention conserves heat and protects portions not covered by the heat shield from excess heat. In addition to being used with a hair dryer, the apparatus can also be used in other applications such as a hand or foot warmer. The apparatus includes a hood cover and a heat shield.During engagement, one end of the hood or source cover is mounted upon the hood of the hair dryer (heat source). The head or heat shield includes one end portion adjustably retained over the scalp and hair of the patron (object to be heated), and the second shield end portion is securely attached to an end of the hood cover. The source cover and heat shield share a common perimeter, as in the preferred embodiment essentially the entire perimeter of the source cover is attached to essentially the entire perimeter of the heat shield.The combination of the hood cover and the heat shield protects portions of the head, neck and face that are not covered from excess heat energy from the hair dryer. To ensure that the combination hair dryer cover is not blown off from the hair dryer when the hair dryer is on, more than one hood cover retainer may be needed. Similarly, to ensure that the head shield is not blown off from the head of the patron when the hair dryer is on, more than one retainer may be needed. The additional retainers are preferably plastic straps or bands. Also, the hood cover includes a plurality of passages through which excess heat energy is vented.For a more complete understanding of the combination hair dryer cover and head shield of the present
    [2" class="description-paragraph] 2 invention, reference is made to the following detailed description and accompanying drawings in which the presently preferred embodiments of the invention are shown by way of example.

    [3" class="description-paragraph] 3 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSReferring now to the drawings, FIGURES 1 and 2 disclose the first embodiment of the combination hair dryer cover and head shield apparatus [10] of the present invention. The apparatus [10] includes a hood cover [20] and a head shield [30]. The apparatus [10] is primarily for use with a hair dryer [11]can also be used in other applications such as a hand warmer or a foot warmer.FIGURE 1 discloses the head of the patron positioned within the hood [12] of the hair dryer [11], while FIGURE 5 discloses the head of the patron removed from the hood [12]. Hence, the apparatus [10] of the present invention is adaptable for patrons of varying heights, and also enables the patron to be removed from the hood [12], thereby reducing noise levels.During engagement, one end of the hood cover [20] is mounted upon the hood [12] of the hair dryer [11]. A first hood cover retainer [22] as shown in FIGURE 3 can be any conventional fastener, such as tape, hook-and-loop type fasteners, but is preferably an elastic band positioned within the perimeter of the end of the hood cover [20].The head shield [30] is retained onto the head [14] of the person using the hair dryer [12]. A first head shield retainer [32] can be any conventional fastener, such as tape, hook-and-loop type fasteners, but is preferably an elastic band positioned within the perimeter of the end of the head shield [30]. The first retainer [32] may be a conventional rubber band or a rubber band that requires the ends to be tied together.The head shield [30] is adjustably retained over the scalp and hair, and onto the head [14] of the patron. The shield [30] and the cover [20] share a common perimeter [40], as essentially the entire perimeter [40'] of the hood cover [20] is attached to essentially the entire perimeter [40"]of the head shield [30] as shown in FIGURE 4.The combination of the hood cover [20] and the head shield [30] protects uncovered portions of the head [14] and face from heat energy from the hair dryer [12]. The hood cover [20] and the head shield
    [4" class="description-paragraph] 4 [30] are preferably both made from a thin clear or tinted plastic material, having a thickness of between 0.50 and 1.40 millimeters, and more specifically of about 0.70 millimeters. Also, the hood cover [20]and the head shield [30] can be made of different materials depending upon the particular application, The material is commercially available from Carlisle Plastics of Minneapolis, Minnesota under the trademark Film-Guardm.The source cover [20] includes a plurality of passages [44] through which excess heat energy is vented. Also, since there are many different types of hooded hair dryers [12], by providing different numbers and configurations of passages [44] of the apparatus [10] is suitable for hair dryers [12] of varying capacities.A second embodiment of the combination hair dryer cover and head shield apparatus [10] of the present invention is disclosed in FIGURE 6. The apparatus [10] comprises a hood cover [20] made from a thin clear or tinted plastic material, having a thickness of between 0.50 and 1.40 millimeters, and preferably of about 0.70 millimeters. One end of the hood cover [20] is affixed onto the hair-dryer [12]and the other end of the hood cover [20] is placed and retained onto the head [14] of the patron.The first hood-cover retainer [22] and head-shield retainer [33] are the primary means for retention of the combination hood cover and head shield apparatus [10] of the present invention during engagement. Secondary retainers may be necessary to ensure retention depending upon the power of the heat source or the temperatures involved as shown in the embodiment shown in FIGURE 6. The first hood-cover retainer [22] is preferably an elastic band, such as a rubber band, which is mounted over the outer perimeter of the hood [12], the elastic band being retained thereabout. The second hood-cover retainer [23] is preferably a cut elastic strap that is affixed to the first hood-cover retainer and is generally normal to the first hood-cover retainer [22] when positioned about and retained onto the hair dryer hood [12]. The second hood-cover retainer [23] is positioned over the hair-dryer hood [12] to secure the apparatus of the present invention [10] to the hair dryer hood [12].Similarly, a second head-shield retainer [33] is positioned under the patron's chin to ensure secure retainment. The second head-shield retainer [33] is affixed to the common perimeter [40] and is preferably a cut elastic band that is normal to the first head-shield retainer [32] when engaged about the patron's chin. A wide variety of other attachment means may be used, including any combination of bands and straps, some being reinforced double or triple bands and straps. Various configurations of hook-and-loop type fasteners may also be used.Once the patron's hair has been conditioned, colored, set in a permanent, or the like using the apparatus [10] of the present invention, the patron's hair needs drying. At this point, the heat source power is shut off and the hood cover [20] is separated from the head shield [30] along perforations [48]disposed about the perimeter of the head shield [30] above and proximate to the head shield elastic band [32] positioned about the hairline of the patron. The perforations [48] may be long and aligned slits, rounded aligned punctures, or the like to enable ready separation of the head shield [30] from the hood cover [20]. Once the central portion of the head shield [30] is separated and discarded, one end of the hood cover [20] is repositioned onto the hood [12] of the hair dryer [11] and the other end is repositioned onto the patron's head. The hair dryer is re-energized and hair drying time is reduced since the heat energy is directed onto the damp hair resulting in a significant energy savings and patron convenience. Similarly, perforations can be added to the hood cover (not shown) and disposed about the perimeter of the hood cover [20) above and proximate to the head shield elastic band [32].Once the upper portion of the hood cover [20] is separated and discarded, the head shield [30] can thereafter be employed as needed.While the combination hair dryer cover and head shield apparatus [10] of the present invention has been discussed herein in relation to applications involving a hood-type hair dryer [12], it will be clear to those skilled in the art that the principles of the present invention have additional applications.In the broadest sense, the combination source cover (hair dryer cover) and heat shield (head shield) apparatus [10] of the present invention conserves heat and protects portions not covered by the heat shield from excess heat. In addition to being used with a hair dryer, the apparatus can also be used in other applications such as a hand or foot warmer. The apparatus includes a hood cover and a heat shield. Also, the invention may be used by football players and other athletes, in subfreezing temperatures to keep hands, feet, and limbs warm or for more extensive bodily coverage. It is evident that many alternatives, modifications, and variations of the combination hair dryer cover and head shield apparatus [10] of the present invention will be apparent to those skilled in the art in light of the disclosure herein. It is intended that the metes and bounds of the present invention be determined by the appended claims rather than by the language of the above specification, and that all such alternatives, modifications, and variations which form a conjointly cooperative equivalent are intended to be included within the spirit and scope of these claims.
