Abstract

A device for drying and/or setting hair which enables the wearer to move about freely during use thereof. The device comprises separate hood and cap members. The cap is constructed of a multilayer, open mesh, moisture-absorbing material which is initially placed over the wearer''s hair. The hood is formed of alternating layers of asbestos or glass fiber cloth with additional layers of heat-retaining fibrous packing and flexible heat-reflecting foil placed therebetween. The hood, after being heated by external heating means to a temperature of about 200* C., is placed over the cap thereby providing the requisite thermal energy for drying the hair.

Ramey Attorney-Berman, Davidson and Berman ABSTRACT: A device for drying and/or setting hair which enables the wearer to move about freely during use thereof. The device comprises separate hood and cap members. The cap is constructed of a multilayer, open mesh, moisture-absorbing material which is initially placed over the wearer's hair. The hood is formed of alternating layers of asbestos or glass fiber cloth with additional layers of heat-retaining fibrous packing and flexible heat-reflecting foil placed therebetween. The hood, after being heated by external heating means to a temperature of about 200 C., is placed over the cap thereby providing the requisite thermal energy for drying the hair.

HAIR-DRYING DEVICE BACKGROUND OF THE INVENTION This invention relates to an improved hair-drying device adapted to give the wearer unrestricted mobility during use thereof.

Present day hair dryers and/or hair setting devices suffer from the disadvantage of restricting the users mobility. For example, a woman sitting under one or more of the commonly used rigid bowl-type devices generally finds the experience time consuming and discomforting. Since conventional devices are generally stationary, the user must remain in a relatively fixed position during the duration of the drying cycle which lasts from about one-half hour to 1 hour. If perchance it becomes necessary for the user to temporarily leave the stationary dryer before the hair is dry, even more unproductive time spent is then required, a part of which is to make up for the heat lost to the cooler atmosphere.

Accordingly, it is a primary object of the present invention to provide a drying device which enables the user to move freely about during the period of hair drying thereby productively utilizing such time without discomfort or inconvenience.

Another object of the present invention is to provide a new and improved hair-drying device having sufficient heat rctaining means to achieve fast and effective hair drying.

Still another object of this invention is to provide a hair-drying device which is economical to manufacture and capable of mass production.

Yet another object of this invention is to provide a hair-drying device susceptible of wide usage at a low cost and having the added advantage of being portable.

A further object of this invention is to provide a hair-drying device having a separate moisture-absorbing heat-resistant cap used in combination with a preheated overlaid hood.

DESCRIPTION OF A SPECIFIC EMBODIMENT Referring now to the drawing in detail, wherein like numerals indicate like elements throughout the several views, a specific embodiment of the hair setting device comprising the subject matter of the present invention is shown as numeral I0. The hair-drying device comprises separate cap and hood members 12 and I4, respectively, used in combination.

Cap 12 is shaped to cover the hair and when placed on the head completely covers the hair from the forehead to the nape of the neck. The cap is preferably constructed of a doublelayer of water-absorbing material such as cotton, linen, muslin and the like. In FIGS. 4 and 5, both inner layer 16 and outer layer 18 are of open mesh construction, formed of one-sixteenth inch or one-eighth inch thick heat-resistant strands. Inner layer 16 may be provided with openings approximately rt; inch or 54 inch diameter, while the outer layer 18 may be provided with somewhat larger openings, on the order of k inch diameter. It should be understood, however, that the exact number of layers, the relative position of said layers, and

the exact reticulated structure may be altered, provided, the cap is constructed with sufficient material so as to effectively remove the moisture from the damp or wet hair while simultaneously protecting the scalp from any excessive heat which may emanate from the hood.

A relatively thin band of elastic material 20 is provided at the lower edge portion of cap 12 adjacent the opening thereof along the outer or inner peripheral surfaces or secured between the

layers

16 and 18.

Hood 14 is designed to fit loosely over the head disposed adjacent to cap 12, being formed of a crown 22 and a body portion 24 ofidentical material construction. Dimensionally hood 14 is about eight inches deep having an inner circumference of about 28 inches.

As best illustrated in FIG. 3, the hood may be constructed of multiple concentric layers disposed cireumferentially in the case of the body portion and arranged vertically in the crown portion, comprising a combination of metallic and nonmetallic materials. Inner layer 26 and outer layer 28 are preferably woven from insulating materials which may be asbestos, glass fiber, or the like.

Intermediate layers

32, 34 and 36 may be of the same material as inner and

outer layers

26 and 28, and serve to separate

additional layers

40 and 42.

A heat-retaining layer 40 is the heat sink compactly placed between

layers

28 and 36, filling the space therebetween and possesses the requisite thermal capacity to effect drying of the hair. Layer 40 may be of any commercially available fibrous or granular material which is physically and chemically suited to the elevated temperature subjected to, e.g. about 200 C. Asbestos, glass wool are examples of such suitable materials. Layer 40 is generally thicker than the other layers comprising the hood, being approximately one-half inch or more.

At least one and preferably two intermediate layers 42 of a flexible metal foil are also provided for heat-reflecting purposes and for regulating the flow of thermal energy from the heat source or layer 40 inwardly to the hair.

As shown in FIG. 3, one specific embodiment of hood I4 comprises five layers of woven glass or

asbestos cloth

26, 28, 32, 34 and 36, the first two separating the heat-retaining fibrous glass wool layer 40, the others being used to separate layers 42 which are flexible aluminum foil. Variations in the exact number and arrangement of the laminate are contemplated. For example, additional foil and cloth layers may be placed outwardly from layer 28, further minimizing heat loss to the atmosphere.

As stated earlier, the crown portion 22 of hood 14 is preferably constructed of the same laminate construction and material as the body portion 24. It may be formed as a separate component and thereafter suitably fastened to the body portion. For example, the crown may be of disclike shape secured along its outer peripheral edge. At the lower edge of body portion 24 an elastic band 52 is also provided.

The hair-drying device of the present invention is to be used in conjunction with any suitable external heat source or supply. One such heat source contemplated is an electrically heated unit small enough to be placed under the hood being capable of fully heating the heat-retaining layer 40 to an elevated temperature, as for example 200 C.

During the time the hood member is being heated, the cap should be placed over the wearer's head and in position ready to receive the preheated hood. Thus, the scalp is protected from any excessive heat emanating from the hood. With the hood in position, sufficient thermal energy is available for removing moisture from the hair at a controlled rate. Due to the rather impervious nature of the hood member, it is imperative that the cap have sufficient material to fully absorb the released moisture.

From the foregoing description, it will become readily apparent that the hair-drying device of the present invention represents a novel and improved device which, when in use, enables the wearer to move freely about and perform a variety of household tasks without any loss of time. Further, the wearer is neither inconvenienced by having to sit erectly for a devices.

While a preferred embodiment of the hair-drying device of the present invention has been described in the foregoing description, it should be understood that this invention is not limited in its scope to the embodiments described, and variations in the form of the invention are contemplated thereby.
