1: Claims. 1

My invention relates to certain new and useful improvements in hair drying devices of the hood type, the characteristics of which will be hereinafter fully described and claimed.

The primary object of my invention is to provide a hair drier that will completely dry a womans head of hair in approximately one-half of the time required by the present hair drying devices now in use.

Another object of my invention is to provide a hood constructed of a flexible material which will eliminate the undesirable conduction of heat usual in the use of the present rigid or metallic hair drier hoods.

Another object of my invention is to provide a construction in a hood for hair drying that will utilize one hundred per cent of the heated air for the drying of the hair by a method of sealing the hood to the user's head without the discomfiture and high heat transmission prevalentin the prior rigid hood type hair driers.

Another object of my invention is to provide a hair drying hood that will distribute the heated air evenly to all parts of the user's hair- 'and which will flexibly conformto all head contours and all head sizes, thereby increasing the ity and efiiciency of the drying process.

A further object of myinvention is to provide a hair drier which will channel the air to the'back of the users head where the'greatest mass of rapid- Y hair is located, the air passing down and out of the hood along the back of the neck, thereby eliminating the discomfort of the heated air passing over the user's eyes and face.

A still further object of my invention is to provide a hair drying device that is adapted to be used with any: type of heating and blower source and particularly adapted to be used in the home with the vacuum cleaner as its source of heated air. Yet another object of thisinventlion is to provide aninexpensive and sanit'a'ry'hair drier which can be folded and compactly stored. 1 1 "Another object of my invention is toprovide a hair drier which, when used by commercial operators, may be sterilizedin quantities and then placed in sealedcontainers for the exclusive use of each individual customer. I

A further object of my invention is to provide an inexpensive hair drier which may be used in almost every home, its drying speed lending itself for use in drying childrens hair and thereby eliminating one of the primary causes of contracting colds and sinus conditions.

Other objects and advantages of the invention will become apparent from the ensuing description in the course of which reference is had to the accompanying drawings, in which:

Referring to the three sheets of drawings of my hairdrier and more specifically to the preferred form of hair drier illustrated by the Figs. 1 to 6, inclusive, Fig. 1 illustrates a hair drier having a pair of tying ribbons 22 that helps retain the hair drier 20 on the head of the user. The hair drier 20 is made of a flexible non-porous material 24 and is formed in the shape of a hood having 5 is a small front elevationalview of the 6 is a small rear elevational view of the a reduced portion 26 that is resiliently mounted.

to a nozzle28 of a tubular member 30. This tubular member 30 can be of any desired shape but my preferred construction is that of an inverted L.

. 'The tubular or conduit member 30 can be affixed by any suitable clamping means 32 to a table 34 or any other projecting ledge and terminates at 35, a point substantially above the floor level. The terminating point 36 has connected to it a flexible hose 38 which is connected to the exhaust end 40 of a standard floor type vacuum cleaner 42. This type of vacuum cleaner has its motor encased in the housing of the vacuum is then carried by the airflow through the exhaust end of cleaner 42, through the flexible hose 38 and tubular member 36 and then passes intogthe flexible and non-porous hood portion 24 of hair drier 20.

The inrushing warmed air flows through a porous mesh-like material 46 which difiuses the incoming air and also acts as an air silencer. The porous member. 46 also serves as a strainer for catching any foreign substance that mayget into the intake of the vacuum cleaner 42, The porous member 46 may also serve to retain a sachet or the like for the scenting of the drying hair.

The reduced portion 26 of the flexible hair drier 20 has a resilient band 56 which firmly encircles the base 52 of a flared portion 54 of the nozzle 28. The end of the flared portion 54 may have a slight projection on it to further aid in the retention of the resilient band 50 to the nozzle portion 528.

The flexible non-porous material 24 has an inner perforated head encompassing portion 56 which may be continuous with the other covering portion of the flexible non-porous material 24. However portions 24 and 56 are shown as being made of two separate pieces and sewn together at their edges 51. The stitching of these two members may be a rather finely sewn stitch for the prevention of air escapage, and being of a plastic material the two sections may be either cemented or heat welded instead of sewn.

The inner headpiece 56 has a multiplicity of perforations 58 for the passing of the heated incoming air to the head and hair of the user. The headpiece 56 is sewn to the outer flexible member 24 at the points illustrated by the reference numeral 60, more clearly shown in Figs. 2, 4 and 5. It is also sewn to the back portion at 62 as shown in Fig. 6. All'of these sewings at 60 and 62 run substantially parallel to each other and spaced apart circumferentially around the hood.

The headpiece 56 is also sewn annularly to the flexible member 24 at 64 around the complete annular forehead portion of the hair drier 20 except for two spaced portions 66 at the back of the flexible hair drier 20. The particular reasons for these various sewn portions 60, 62 and 64 will hereinafter become apparent.

As the air passes through the porous member 46 difl'using and spreading into the interior chamber 68 the warm air under pressure causes the expansion and inflation of the outer flexible non-porous member 24. Simultaneous with the inflation of flexible member 24 the warm air passes down and through the two spaced portions 66 at the rear of the hair drier 20 and passes circumferentially around a head sealing portion Sealing portion 10 expands and prevents any substantial escape of the air around, the greater portion of the users head except at the rear 12,

I more clearly shown in Fig. 3.

The air entering interior chamber 68 produces arcuate air cushion members 14 around the entire outerand interior head portions of the hair drier thus conforming snugly to any head contour or head size. The warmed air passing through the perforations 58 is evenly distributed to all parts of the user's wet hair. The air under pressure then seeks an outlet. Because of the sealing effect of the pressurized sealing chamber HI around the greater portion of the head the air seeks an escape through an area of least resistance mainly through openings 13 as provided at the rear of hair drier 20, also because of the sealing chamber permitting the flow of air out through the rear or back portion 12 of the hair drier 20.

It can readily be seen that the incoming warmed air will be utilized to the fullest efliciency by its equal dispersion over every portion of the a head where the greatest mass user's hair and all of the outflowing air will be concentrated and directed over the rear of the of hair is located, thereby making full use of the warm air which would otherwise escape all around the head, and providing a maximum of comfort to the user.

In the modification illustrated in Fig. '7 there is shown a flexible non-porous outer member 80 and a perforated flexible inner headpiece 82. The outer member so is connected resiliently at 84 to a nozzle 28 similar to the preferred form as heretofore described.

The hood member 86 has a resilient head sealing portion 88 and two openings 90-410 connected with the outer and inner members 80 and 82. The two orifices 90-90 are provided for the emission of the outgoing air from the chamber 92. The air. passing first into an outer chamber 94 also produces a series of arcuate air cushions 98 because of stitching I00. Stitching'lllll runs substantially vertical and joins the inner perforated headpiece 82 to the outer flexible member 80,

The air then passes through perforations 96 through the hair and then flows out of the two orifices 98-90.

Another modification illustrated in Fig. 8 may be identical in construction with my preferred embodiments shown in Figs. 1 to 6, inelusive, except for the inner headpiece Me which is made of a porous mesh-like material instead of a perforated non-porous material.

In Figs. 10 and 11 are illustrated a modified form of an air diffuser H5. This construction may be comprised of a plurality of screens H6 held in a retaining assembly H8, and may be easily disassembled as desired. The retaining assembly H8 may also hold a sachet as shown at I20.

The primary function of the screen members H6 and porous mesh-like member 46 is for the diffusion of the air and for the prevention of a too highly pressurized concentration of air directly on top of the user's head.

In conclusion, although my invention has been disclosed in connection with the specific details of. preferred embodiments thereof, it must be understood that such details are not intended to be limitative of the invention except so far as set forth in the accompanying claims.
