7 Claims. (Cl. 34-90) This invention relates to treatment of the human body and more particularly to an apparatus for drying human hair after washing thereof or after any other treatment which leaves the hair in such a condition as to require drying thereof.

Heretofore, many types of hair drying apparatus have been developed and utilized and such apparatus has in general been entirely satisfactory for what might be termed professional use. However, these prior art hair dryers primarily intended for professional use, are exceedingly massive and costly and in many instances are of such a nature as to prohibit their use in the home. Such hair dryers as have heretofore been proposed for home use have in the main been relatively simple hand held blowers and the like, in which a blast of heated air is directed on the hair of the person, but obviously, these particular types of hair dryers are exceedingly inefficient and also cumbersome and fatiguing to use. The inefii ciency of these hand type hair dryers is caused to a great extent, by the inability to direct the stream of air only upon the hair being dried, since such stream of air is dissipated from the dryer substantially in a wide angle cone and consequently a large portion thereof does not contact the hair and furthermore, this air does contact the face and other portions of the body thus increasing discomfort and detracting from the efiiciency of the device.

it is accordingly an object of the invention to provide a hair dryer which may be economically constructed and which is entirely suitable for use in the home.

A further object of the invention is the provision of a hair dryer which may he applied to the head of the user in a comfortable manner and in which all of the heated air emanating from the dryer is directed onto and through the hair of the person, and the air discharged from the device in a direction away from the person, thus reducing discomfort.

A still further object of the invention is the provision of a hair dryer for home use which may conveniently utilize a conventional vacuum cleaner of the so-called canister type to provide a source of air under relatively low pressure for circulation through the heating elements of the dryer and into contact with the hair to be dried.

Another object of the invention is the provision of a hair dryer which may conveniently utilize a conventional vacuum cleaner of the so called tank type in order to provide air under relatively low pressure to circulate through the heating elements of the dryer and into contact with the hair to be dried.

A further object of the invention is the provision of a hair dryer incorporating a motor driven fan for circulating air through the heating elements and into contact with the hair to be dried.

A still further object of the invention is the provision of a hair dryer for home use which is substantially collapsible and which may be removed or disconnected from a vacuum cleaner after use thereof and. conveniently stored in a relatively small space.

ice

A still further object of the invention is the provision of a hair dryer incorporating means for directing the flow of air onto the hair to be dried and for preventing flow of such airover the face or other portions of the body outside the area occupied by the hair to be dried.

Another object of the invention is the provision of a hair dryer in which means is provided for directing the ilow of discharged air away from the person utilizing the dryer.

A further object of the invention is the provision of a hair dryer which may be utilized by a person with a maximum. of comfort and in which the entire volume of air is utilized for drying the hair thereby materially increasing the efhciency of the device.

Further objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawing: wherein:

With continued reference to the drawing there is shown in Fig. l, a hair dryer constructed in accordance with this invention and which may well comprise an elongated tubular supporting standard it) provided at its lower end with a flanged coupling member 11 having a downwardly depending skirt or annular flange 12 which may be received within a cup-shaped recess 13 in the top wall 14 of a canister-type vacuum cleaner 15. The bottom wall of the cup-shaped recess 13 is provided with an aperture 17 through which air is discharged from the cleaner 15. T he side wall 13 of the cup-shaped recess 13 may be provided with inwardly extending pins 19 which are received in bayonet slots 2% in the downwardly extending annular flange 12 of the flanged coupling member 11 in order to detachably couple the supporting column it) to the cleaner it's in communication with the interior thereof and in such a manner that air will be blown through the interior of column 10.

end of column 10, the nut 23 being provided with an inwardly extending annular flange 25 engaging the upper end of the washer or collar 22 and thereby compressing such washer 22 into tight engagement with the supporting member 21, to hold the same in adjusted relationship to the column 10. In order to counter balance the weight or"v the column 10 and the portions of the apparatus carried thereby there may be provided Within the column 10 a compression spring 26, the upper end of which engages the lower end of supporting member 21 and the lower end of which engages the flanged coupling member 11, as best shown in Fig. 5. Thus the supporting member 21 may be adjusted up or down in the column 10 in order to suitably position the apparatus for use by a person seated in a chair of any convenient height.

The supporting member 21 may be provided at its upper end, with a gooseneck 27 having a downturned end 28 which serves to adjustably support a hood 29 in a manner to be presently described.

With particular reference to Fig. 2, the hood 29 may well comprise a bell-shaped outer casing 30 provided at its upper end with a thickened portion 31 in which may be disposed a spherical recess 32. Recess 32 serves to receive a ball 33 which may have an aperture extending therethrough to receive the end 28 of the gooseneck 27 on supporting member 21. The end 28 may be removably secured in the ball 33 by a pin or other suitable means 34 extending through a collar 35 formed as part of the ball 33 and through apertures in the end 28 of the supporting member 21.

The ball 33 is retained in the recess 32 and in resilient engagement with the wall thereof, by a plate 36 having a spherical aperture 37 therein, the surface of this aperture being in engagement with the surface of the ball 33 and in opposition to the spherical recess 32 in the thick ened portion 31. The plate 36 is held in engagement with the ball 33 by compression spring members 38 received around rods 39 slidably extending through apertures in the thickened portion 31 and secured to the plate 36. Thus the structure just described, provides a ball and socket joint for supporting the hood 29 on the supporting member 21 and obviously, the head 29 may be conveniently removed therefrom for transportation or storage purposes by removal of the pin 34.

The lower end of hood 29 is provided with an annular groove 40 which may serve to receive the upper edge 41 of a flexible band 42 which may be held in place in the groove 40 by a draw string 43 or by any other suitable means. The lower edge of band 42 is also provided with a drawstring 44 which may be utilized to secure the band 42 about the head of the user and below the hair line.

The shell 30 of the hood 29 is provided adjacent the lower edge thereof, with a plurality of apertures 45 extending entirely around the circumference thereof, and these apertures are grouped more to the back of the users head where the most hair is, and these apertures communicate with an annular recess 46 formed by an upstanding annular flange 47 spaced outwardly from the outer wall of shell 30 of hood 29. Thus, air within the hood 29 may flow outwardly through the apertures 25 and due to the annular wall or flange 47 will flow upwardly and out of the hood 29 away from the face and body of the user.

Mounted within the hood 29 is a bafrle in the form of a bell shaped shell 48, which baffle is secured at its lower edge 49 to the shell 30 of hood 29, and the bathe 48 is provided with a plurality of apertures 59 therein, through which is is adopted to flow into contact with the hair of the user. As shown in Fig. 2, the apertures 5b are so disposed in the battle 48 as to direct air into contact with the hair of the user and away from the area around the ears of the user. The apertures 50 also serve to direct the air therethrough onto and into the hair of the users head with jet like force. Apertures are so placed so as to direct the air away from the ears of the user, and to be so distributed so that the major portion of the air is directed at back of the users head where most of the ladies hair is located.

Disposed within the hood 29 and located above the battle is a heating element 51, which is best shown in Figs. 1. and 3, may comprise a circular disc 52 of ceramic or other suitable material, which disc serves to support a heating coil 53. Coil 53 may be connected through suitable leads 54 with a control switch 55 having finger engaging knob 56 located externally of the hood 29 in order to permit controlling the temperature of heating element 51. Electric supply leads 57 may extend through a grommet 58 in the shell 30 of the hood 29, and be connected to the switch 55 and the heating element 51 in order to supply electric current thereto. The disk 52 supporting the heating elements 53 may be secured in place in the shell 30 of the hood 29 by a strap 59 extending around the disk 52 and secured thereto by screw threaded fastening means or the like 60 extending through cars 61, on the strap 59, and such strap 59 may be provided with laterally extending bracket members 62 which in turn may be secured to the shell 30 of the hood 29 by screw threaded fastening means or the like 63.

It will thus be seen that by the above described form of the invention air under relatively low pressure may be supplied by the vacuum cleaner 15 and such air will flow upwardly through the column 10 and the supporting member 21 into the interior of the hood 29. This air will thereafter flow through the heating element 51 and through the apertures 50 in the ba'flie 48 and into contact with the hair of the user. Thereafter such air will flow outwardly through the apertures 45 and upwardly through the annular channel or recess 46 to the external air and away from the face and body of the user. Furthermore, the hood 29 will be secured in fixed relationship with the head of the user by means of the flexible band 42 and likewise, this band 42 will prevent leakage of air around the lower edge thereof and down over the face and body of the user. Consequently, all of the heated air will be utilized to dry the hair of the user and due to the disposition of the apertures 50 in the baflle 48, will be directed away from the ears of the user.

By reason of the detachable connection between the supporting member 21 and the ball 33, the hood 29 may be detached therefrom and likewise, the column 10 may be detached from the vacuum cleaner 15 which permits the vacuum cleaner to be utilized for other purposes and also permits convenient storage of the hair dryer of this invention in a relatively small space.

In Figs. 7 and 8 there is shown a modified form of the invention in which a pedestal 64 may be detachably secured to a base 65 by means of a removable pin 66 and a tubular supporting member 67 may be slidably received in the upper end of pedestal 64, and clamped in adjusted relation thereto by a nut 68. The upper end of supporting member 67 may be provided with a gooseneck 69 which is detachably secured at its end 70 in a ball 71 received in a spherical recess 72 in the thickened upper end 73 of a bell-shaped hood 74. The ball 71 is held in adjusted relationship to the hood 74 by a plate 75 having a spherical aperture 76 therein, which engages the surface of the ball 71, the plate 75 being urged into engagement with the ball '71 by compression springs 77 received around rods 78 which are slidable in apertures in the thickened portion 73 and secured to the plate 75. The lower end 79 of the gooseneck portion 69 of the supporting member 6''] may be detachably secured to the ball '71 by a removable pin 79 much in the manner of the connection described above, in connection with the form shown in Fig. 1 of the drawings.

The hood 74 is formed by a shell 80 provided with an annular groove 81 adjacent the lower end thereof, which serves to receive the upper edge 82 of a flexible band 83 which is provided with a drawstring 84 adjacent its upper edge and a drawstring 85 adjacent its lower edge, for securing the end in engagement with the head of the user below the hair line. The shell 80 is provided with a plurality of apertures 86 extending around the circumference adjacent the lower edge thereof, these apertures 86 communicating with an annular channel or recess 87 provided by an upstanding annular flange 88 in spaced relation to the outer surface of the shell 80, thus permitting discharge of air from the interior of the hood 74, upwardly and away from the head and body of the user.

Within the shell 80 of the hood 74 there is provided a hood shaped baflie 89 secured at its lower edge 90 to the shell 80 of the hood 74, the baffle 89 being provided with a plurality of apertures 91 which served to direct air therethrough onto the hair of the user.

Disposed above the baflle 89 and within the shell 80 of the hood '74 is a heating element 92 which is identical in every way with the heating element described above in connection with the form of the invention shown in Figs. 1 and 2, and there is likewise provided a control switch 93 having a finger engaging knob 94 externally of the hood 74 in order to properly control the temperature of the heating element 92. Electrical current may be supplied to the. heating element 92 by a suitable conductor 95 extending through a grommet 96 in the shell 80 of the hood 74.

Disposed within the shell 80 of the hood 74 and above the heating element 92 is an electric motor 97 which may be supported by a suitable bracket 98 secured to the shell 86 by screw threaded fastening means or the like 99. Motor 97 is provided with a drive shaft 100 on which may be mounted a fan 101 disposed directly above the heating element 92. The motor 97 may be supplied with electrical energy through a suitable conductor 102 extending exteriorly of the shell 80. The shell 80 adjacent the upper end thereof is provided with a plurality of apertures which may be covered with screening or other suitable material 1M to permit entry of air where by upon rotation of the fan 101, such air will be drawn into the hood '74 blown downwardly over the heating element 92 and through the apertures 91 in the baiiie 89 into direct contact with the hair of the user. The air thereafter will be discharged through the apertures 86 and upwardly through the annular channel or recess 87 to the exterior of the hood 74 and away from the face and body of the user.

The form of the invention, above described and shown in Figs. 7 and 8 provides a completely self-contained hair drying unit which may be conveniently dismantled for storage purpose by removing the column 64 from the base 65 by removing the hood 74 from the supporting member 67. This form of the invention, of course,'also incorporates the means described in connection with the first form of the invention for directing the air into intimate contact with the hair of the user while avoiding contact of such air with the ears and with other parts of the face and body. i

The form of the invention shown in Fig. 9 is identical with that shown and described in connection with Figs. 1 and 2. of the drawing except that a supporting pedestal 195 is detachably secured to a base 106 by a removable pin or other suitable means 107 and the pedestal 105 is provided with a laterally extending tube 108 communicating with the interior thereof, and adapted to receive the coupling member Hi9 on the end of a hose 110 which may be attached to the conventional tank type vacuum cleaner 1M. This hose 110 will, of course, be attached to the discharge end of the cleaner 111 in order to provide relatively low pressure air to the interior of pedestal 105 and consequently, to the interior of the hood 112 which is identical with the hood 29 shown in Figs. 1 and 2 of the drawing and adapted to engage the head of the user in the same way.

It will thus be seen that by the above described invention there has been provided a hair drying apparatus which may be utilized in connection with conventional vacuum cleaners normally found in many households and which vacuum cleaners serve to provide a source of low pressure air for use with the hair drying apparatus of this invention. Furthermore, this hair dryer provides means for comfortable attachment to the head of the wearer whereby the air is efficiently utilized in intimate contact with the hair of the user and in which such air is directed away from the ears, face and body of the user and in such a manner that maximum drying efficiency is obtaine The hair dryer of this invention is collapsible in order to permit convenient storage or transportation thereof in a relatively small space, and furthermore, may be economically manufactured whereby the same will be attractive for home use.

The invention, as above described, further contemplates a self-contained hair dryer in which the blower is provided therein, but this form of the invention also includes the desirable features of the other forms of the invention and may still be manufactured at a relatively low cost when compared with so-called professional equipment.

it is further to be understood that the particular types of vacuum cleaners described and shown in the drawing are for illustrative purposes only, and the apparatus of this invention may be utilized with any conventional vacuum cleaners which provide an outlet for the air to which the apparatus of this invention may be attached.

It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is shown in the drawing and described in the specification, but only as indicated in the appended claims.
