11 Claims, 6 Drawing Figures HAIR DRYER BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to hair drying apparatus and that particularly adapted to dry ones long hair as well as that on a persons scalp.

2. Description of the Prior Art The problems of drying long hair has been under consideration over the years. Illustrations of various prior art apparatus are shown, for example, by United States Letters Patent to MACI-IADO No. 495,558 issued Apr. 18, 1893; WIRTH US. Pat. No. 1,514,495, issued Nov. 4, 1924; in British Patents to HORNUNG, No. 22,463 of 1902 and BULLOCK, No. 1030,172 of May 18, 1966, and German patents to MARTH, No. 95,503, of 1897-1898; HORNUNG, No. 130,146; and URBACH, No. 146,644.

Long hair styles have once again become fashionable and are worn by all sexes. Over the years, the technology and research in hair and hair drying, as well as improvements in mechanical components, has enabled hair stylists to be much more aware of the problems unsolved, consider comfort of the individual and consider the amount of time for drying the hair.

Split ends or split hairs are important factors, and microscopic examination of a strand of hair reveals many filaments protecting from the longitudinal axis of the hair strand.

SUMMARY OF THE INVENTION The present invention relates to an improved long hair drying apparatus in which a suction-blower communicates with a pair of juxtapositionable manifolds; one manifold facilitating the combining and brushing of wet hair thereon and the manifolds form a hair chamber in which the circulation of air therebetween drys and lays down loose hairs whereby long hair dried therein, depending on the hair thickness, weight, porosity, and wetness of the hair, takes from about 10 to 25 minutes and in which the hair maintains a sheen and appearance resulting from the hair split ends being dried while lying along the longitudinal axis of the hair.

Another feature of the invention relates to adjustable means incorporated with the displacable manifold which dries the hair or a persons scalp permitting all hair styles to be dried on the present apparatus thus providing versatility to the apparatus as well as providing an air-exchange feature circulating fresh air through the dryer.

These, together with other and more specific objects and advantages,'will become apparent from a consideration of the following description of an overplay embodiment when taken in consideration with the drawings for a part thereof.

FIG. 2 is a perspective view of the apparatus in FIG. 1 along the hinged manifold in an open position;

FIG. 3 is another perspective view of the apparatus in an open position showing details of the fixed manifold on which long hair is laid and combed;

FIG. 4 is an enlarged fragmentary section taken substantially on the plane of line 4-4. of FIG. 1 with portions broken away;

FIG. 5 is an enlarged fragmentary section taken substantially on the plane of the 5--5 of FIG. 3; and

FIG. 6 is an enlarged, fragmentary side elevational view of a control panel incorporated on one of the manifolds.

DESCRIPTION OF THE PREFERRED EMBODIMENT Before referring to the drawing in detail, the apparatus can be constructed of any suitable material, i.e., plastic, glass fiber reinforced plastic, metal panels, etc. The apparatus is indicated generally at 10 and comprises a generally rectangular lower housing member 12 conveniently incorporating suitable casters 14. The housing member 12 includes a vertically extending manifold portion 16 which is hollow and includes a generally hollow chamber 18 defined by an upper foraminous panel 20 which in the exemplary embodiment is at about a angle with respect to the vertical, however, this angle can vary. The upper end of the manifold portion 16 is slightly contoured or convex at 22 for conveniently accommodatingthe nape of a persons neck; see FIG. 1. The person using the drying apparatus will be seated forwardly of the manifold portion 16 and the foraminous panel conveniently comprises means whereby the hair stylist can readily brush the person Ps wet hair into a straight oriented position in which it will be dried. Secured in longitudinally bordering relationship to the elongated foraminous panel 20 are suitable sealing elements 23 (only one shown in FIG. 1) which seal in air being circulated through the manifold portion 16.

Hinged on a transverse hinge 24 at the rear upper edge of the housing member 12 is a second hollow manifold member 25 which is generally triangular in side elevation and which is complimentary to the manifold portion 16. The 2nd manifold member includes

side panels

26, 28 depending below at their lower edges, beneath a foraminous panel 30 and which will form with the panel 20 a hair-receiving chamber 32 in which the long, combed hair will be received in the attitude in which it will be dried.

The chamber 32 forms at its upper end an opening 34 which permits fresh air to be introduced into the drier. The manifold member 25 is limited in its pivotal movement when in an open position, i.e., to the position shown in FIGS. 2 and 3. The means for limiting pivotal movement comprising a contoured stop-track element 36 anchored at 38 on the side of the housing member and including a rearwardly extending guide track 40 reciprocably receiving therein a lateral pin 41 fixed to the lower end of the manifold member 25 (a pair of the contoured stop-track elements can be utilized on the relatively hinged parts).

The housing member 12 includes therein a suctionblower means 42 comprising a centrifugal or squirlcage fan, however, the suction blower means can comprise a central suction-blower of an enlarged ca pacity whereby a bank or plurality of the dryers can be serviced by a single suction-blower. The suction-blower includes a housing 44 having an axial inlet opening 46 communicating with a drum-type rotor, suitably journaled in the housing and driven by an electrically energized rotor 48. The rotor 48 discharges air centrifugally through opening 50 to an outlet chamber 52; see FIG. 4, which includes therein heater means 54 comprising resistance wires 56 and over which forced air is passed and tempered. The outlet chamber 52 includes flanged outlet portions 58 to which are secured by clamps 60 inlet ends of expansible or accordion-type conduits 62 which are suitably connected at 64 (see FIG. 2) to the manifold member 25.

In the absence of further explanation, air forced from the suction blower means 42 passes through the conduits 62 to the manifold member 25, through foraminous panel 30 into chamber 32 where the hair has previously been combed and brushed; through the hair and the foraminous panel 20 into chamber 18 and then into the inlet opening 46 of the suction-blower housing 44.

The drying can be effected in approximately minutes, and it will be observed that the direction of movement of air, see direction arrows on FIG. 1, causes the manifold member 25 to be urged into the closing direction, and because split hairs when wet, are combed and laid on panel 20, it has been found that the hair when dried in the manner just described, not only does the hair have an unusual sheen, but the hair retains this sheen over an extraordinary period of time and maintains this straight condition. This unusual result is apparently due in part to the fact that the hair is pressed or drawn down onto panel 20 during the normal movement of air, and the split hair filaments are dried along the longitudinal axis of its respective hair strand; this reinforces the hair strand along its length and, since it is not appreciably disturbed while drying, the hair is maintained in its straight condition over an unusual length of time. The apparatus is likewise adapted for producing styles including waves or curls which can be effected by finger waving the wet hair, forming pin curls, or applying suitable hair rollers by the hair stylist.

The housing 12 includes between the chamber 18 and the inlet opening 46; supported on a suitable support ledge 66, an intermediate filter element 68 of any suitable construction which will filter all air drawn into the opening 46 and loose hair etc. so that the air is maintained in a debris-free condition; the filter element 68 will be changed or cleaned periodically.

In addition to drying long hair, the apparatus includes means for drying the hair at the person s head. Integral with the upper panel 70 of manifold 25 is a tubular sleeve 72; see FIG. 5, which telescopically receives a sleeve 74 having an angled lower end 76 forming a scoop opening in the direction air enters the manifold 25 from the conduits 62. The sleeve 74 is vertically adjustable and has one end 77 connected at 78 to a flexible tape 80 which is threaded through an opening 82 into an apertured housing 84 in which the tape is convoluted at 80'; suitable clutch means 86 is provided whereby the sleeve 74 (see dotted line position) is retained in an adjusted position and the tape 80 is readily rewound as the tape moves upwardly during upward movement of the sleeve from the-position illustrated in FIG. 5.

Telescopically connected to the upper end 74 of the sleeve 74 is a complimentary tubular sleeve 88 retained thereon by a threaded screw 90 having an enlarged handle 92 received in a suitable tapped opening in sleeve portion 74; the sleeve 88 incorporates a slot 94 affording sufficient adjustment relative to the person Ps head. The sleeve 88 incorporates a handle 96 providing the hair stylist means for readily raising and lowering the manifold and attachments thereon. The sleeve 88 includes at 98 a transverse hinge 100 and to which is pivoted a head-hood manifold means 102 permitting the manifold 25 to overly manifold portion 16 (when drying short hair, to permit the person P to be readily seated, move away from the dryer etc. The head-manifold means includes the usual inner foraminous head plate 104; the head manifold 102 will suitably seal on the end of conduit 88 when it is in the solid line position shown in FIGS. 1 to 3.

Referring to FIG. 6 without showing the detailed wiring circuits, a control panel 106 incorporates a timer 108, heat control 110, switch 112 as well as light 114 of a green color to indicate that'all conditions are proper for drying, and a light 116 (red for example) to indicate an overheat condition, for example.
