Oct. 13, 1964 W. HUPKA HAIRDRYER HOOD Filed June 26, A1961 F ig. 2

53 52 5l i0k 32 33 30 /7 @zu f fw@ United States Patent O 4 Claims. 5cl. sri-99) This invention relates to hairdryer hoods.

The hairdryer hood commonly used by hair-dressers comprises a hood top and an integral metal drying chamber to form a linger hood respectively a whirlwind hood with direct or indirect hot'air guideways. Such bulky appliances of high weight which are adjustably mounted on a stand can only be used for commercial purposes as e.g. in hairdresser shops. k

`.For domestic purposes on the other hand hairdryer hoods are known which e.g. consist of an air-,fed bag, which by means of ribbons may be tightly secured at the forehead and in the neck. The airtight fastening of the hood from the forehead to the neck is very inconvenient and troublesome and in addition when handling the hood the hair style is easily upset by the direct admission of the air tlow. Also a non-uniform drying effect occurs.

-With respect to such drawbacks one object of the invention isto provide a hairdryer hood which also as domestic appliance may meet the requirements Lfor a satisfactory air tlow and for a uniform drying effect. The invention resides in the provision of a hairdryer hood, the top of which is provided with `a drying chamber consisting of interconnected collapsible wall elements which in uncollapsed position form a bell-shaped hood for receiving and guiding the air iiow.

The top of the hood may be designed as a cavity for admission and distribution of the drying air, or such cavity may receive a ventilator set with the necessary motor and the heater elements. y

The collapsible wall elements for feeding and guiding the air and for forming the drying chamber may be differently designed.

According to the preferred embodiment the drying chamber comprises interconnected slightly tapered concentric rings which in extended position form the hood jacket.

The top of the hood is provided with suitable means for suspending or setting up as e.g. a carrier arm or the like, so designed that the drying chamber in its working position may easily receive the womans hair to be dried.

The accompanying drawings illustrate one embodiment of the invention, constructed according to the best mode so far devised for the practical application of the principles thereof, and in which:

FIG. l is `an elevation `and partial section of a dryer hood consisting of a plurality of ring elements in working.

position,

FIG. 2 is an elevation `and partial section of the dryer hood according to FIG. 1 in vnon-operating position.

In the drawings reference number refers to the topy of the hood, reference number 11-to the air intake and reference number 12 to they bell-shaped drying chamber.

In FIGSfl and 2 the top member 10 of the hood is*k provided with a ventilator appliance consisting of air circulating means here shown as an electric motor 30 and driven ventilator wings 31 located in a space deiined by an inner annulus or ring 51 extending downwardly from the top member. When using the ventilator the airl enters viav the air inlet 11 and/or via the air inlet opening 32, adjacent to air heater means' 33. An electric switch 50 preferably has three switching positions.`

The drying chamber 12 consists of a series of annular substantially rigid truste-conical elements here shown as

concentric rings

51, 52, 53, 54, 55, the diameters of which slightly increase from top to base of the hood. The outermost ring 55 is provided with an inwardly curved edge portion. As seen from FIG. 2 the rings 51 to 54 may be put into the annular space 56 of top 1li. For this purpose the top 10 of the hood is provided with a projecting ring or outer annulars 57 which at its free edge may be provided with locking means 58 for the outermost ring 55 and which defines between itself and the inner annulus 51 a storage space for receiving the rings. In collapsed condition the whole appliance has the appearance of a disk-like body which at its one surface is closed by the screen 46 with the inwardly curved ring 55 bridging the annular storage space 56. The telescoping ring elements 51 to 54 in a manner known perse may be provided with special stops and abutments and also may at their inner faceshave air guiding members 59.

The top of the hood 10 is' provided with mounting means 60 as e.g. a holding arm, a holding clamp, a suspension arm or the like, for facilitating the putting up of the dryer hood in convenient operating condition.

The top 10 of the hood may be provided with a ventilator appliance. On the other hand it is likewise possible to provide the hood with means for admitting air from a separate air source, e.g. the air may be Supplied by a vacuum cleaner.

All structural elements of the dryer hood, except the motor may consist of heat resistant synthetic materials.

The telescoping rings 51 to 54 respectively the top 10 and the outer edge 55 according to FIG. l consist of solid y heat-resistant synthetic materials respectively completely or partly of metal.

A hairdryer hood according to the present invention enables an air flow comparable with that of the socalled whirlwind hoods. The hair with the desired hair style is uniformly dried. An upsetting of the hair is not possible. So also in a household the same desired results are attainable which up to now only were obtainable with the commercially used bulky appliances of hairdressers. The production from synthetic material leads to a very nice and convenient appliance. The hood jacket has to be designed vsuch that the head of the woman may easily be brought into the desired position with respect to the top of the hood.
