INVENT'DR V/RG/N/A B. TOULM/N BY V ATTORNEYS United States Patent 3,188,362 HAIR DEER Virginia B. Toulmin, Dayton, Ghio, assiguor to The Commonwealth Engineering Company of (this, Eayton, Ohio, a corporation of Ohio Filed Jan. 16, 1961, Ser. No. 83;,ti38 1 (Iiaim. (Cl. 3499) This invention relates to a hair drier and more particularly to a hair drier which includes the power source.

The invention essentially comprises a helmet or a cap containing battery-powered ventilating means and/ or heating means.

While numerous forms of electric hair drier-s have been proposed, most of these devices have to be connected with a power outlet by means of an electric cable and plug thereby forcing the user of the drier to remain stationary while the drying operation takes place.

It is the principal object of the invention to provide a hair drier in one self-contained unit which is independent of any outside power source.

Aonther object of this invention is to provide a hair drier which is light in weight.

A further object of this invention is to provide a hair drier which is simple in both construction and operation.

Other objects and advantages of the invention will be apparent from the following description in conjunction with the accompanying drawings, in which like numerals refer to like parts throughout the several figures, and wherein FIGURE 1 is a side view of the preferred embodiment of the hair drier;

FIGURE 2 shows a side view of the same embodiment partially in section and with a portion of the lower edge broken away;

FIGURE 3 is a side View of another embodiment of the invention with portions broken away.

Referring now to the drawing more in particular, FIG- URE 1 shows the preferred embodiment of the invention where the drier body is a helmet 1 of rigid, lightweight material. On the top of the helmet 1 there is a cover 2 which surrounds a motor and is provided with openings 3 for the passage of cooling air. A supporting structure 4 which is fixed to the inside of the helmet 1 and has a neck roll 5 and ear curves 1% provides a suitable means for properly positioning and supporting the helmet 1 on the users head. A switch 6 is connected by way of a cord 7 with the motor underneath the cover 2.

FIGURE 2 shows a motor 8 under the cover 2. The motor 8 is connected with a battery 9 by connecting lines which are not shown. The motor 8 drives a fan 10 which is adapted to pull air through the helmet which enters at points 11 and leaves the helmet again through apertures 12. Inside the helmet 1 there are further provided electrical resistors 13 which operate as heaters. The air which is drawn up inside the helmet 1 is heated by the resistors 13 thereby carrying out the intended drying of the hair. An .apertured shield 14 is arranged underneath the fan 10 so that any contact between the fan blades and the hair is avoided.

The modification shown in FIGURE 3 differs from the preferred embodiment shown in FIGURES 1 and 2 in that the drier body consists of a rigid frame 16 which is 3,103,862 i atented Qct. 29, 1963 covered by a hood 1! of a reticulated fabric. The drier is held in place on the users head by means of a head band 18 which is anchored inside the frame 16, so as to insure a proper fit of the drier on the users head. Inside the frame 16 there are electrical heaters 13 of the resistor type which are connected by wires (not shown) with a battery 19 which is provided underneath a cover 2. By actuating a switch 29 the circuit is closed and heat is radiated from the resistors 13 thnoughout the space between the drying hood "l7 and the head, thereby carrying out the intended drying of the hair. The humid air escapes through the reticulated fabric of the hood 17. Two ear openings 21, of which only one is shown, are provided in the hood 17. A clasp 2 2 or the like is arranged at the lower front ends of the hood 17 thereby allowing the drier to be snugly closed under the users chin.

It is obvious that both embodiments of the invention afford the important advantage that the hair drier can be worn and operated without connection to an outside power source. Thereby the need for a cord is obviated and the user can move freely around during hair drying. This is important for housewives who can carry out their chores while drying their hair which is not possible with a hair drier that has to be connected with an outside power supply. The self-contained drier according to the invention also proves invaluable in areas without or with unreliable elcctric power service, on camping trips or while travelling.

It will be understood that this invention is susceptible to modification in order to adapt it to different usages and conditions, and, accordingly, it is desired to comprehend such modifications within this invention as may fall within the scope of the appended claim.

What is claimed is:

A hair drier comprising a lightweight helmet, said helmet having apertures in the top portion thereof, a cover mounted on said helmet, an electric motor disposed in said cover, a fan comprising fan blades extending downwardly within said cover from said motor on a rotatable shaft, a supporting structure attached to said helmet, a neck roll mounted on the lower rearward end of said supporting structure, means comprising ear curves disposed on said supporting structure for stabilizing said helmet on a users head and in spaced relationship relative thereto, electric heating elements, a dry cell battery, said heating elements and said battery being fastened to the inside of said helmet, electric wiring interconnecting said motor, battery and heating elements, and a switch connected with said motor for actuating said fan motor and heating elements thereby causing air to be pulled into said helmet from below, heated and expelled through said apertures.
