The present invention relates to a hair dryer and, more particularly, to a hood for a hair dryer, and especially to a hair dryer hood adapted for use in hair drying apparatus of the type in which the air-heating and air-blowing mechanism is remote from the hood and is connected thereto by conduits.
It is the primary object of the present invention to provide a hair dryer hood, of the character described, that may be most easily, conveniently and comfortably fitted about a head and as easily, conveniently and comfortably removed from the head.
More specifically, it is an object of the present invention to provide a hair dryer hood, of the character described, which may be fitted over the head of the user, rather than require the head of the user to be fitted thereinto, as is generally required with hair dryer hoods of the prior art.
It is another object of the present invention to provide a hair dryer hood that is of light weight and compact and easy and convenient to install.
It is still another object of the present invention to provide a hair dryer hood, of the character described, that will avoid giving the user a feeling of confinement, such as might cause unease and discomfort to the user.
It is a further object of the present invention to provide a hair dryer hood, of the character described, which, though light of weight, is strong and durable.
It is a still further object of the present invention to provide a hair dryer, of the character described, which is of relatively simple construction, yet eificient for its purpose and may be relatively easily and economically massproduced for use in the home.
The foregoing and other objects and advantages of the hair dryer hood of the present invention :will become more readily apparent to those skilled in the art from the embodiment thereof shown in the accompanying drawings and from the description following. It is to be understood however, that such embodiment is shown by way of illlustration only, to make the principle and practice of the invention more readily comprehensible, and without any intent of limiting the invention to the specific details therein shown.

Generally stated, the present invention consists in the provision of a hair dryer hood, of overall dome or hemi- 3,313,37 Patented Apr. 11, 1967 spherical shape, which is formed of two separate, substantially equal complementary halves, each half comprising an outer wall and a perforated inner wall spaced from the outer wall; and each half individually hingedly supported at one end for movement into juxtaposition with and away from the other half, and each having the space between its walls connected to a source of blown More specifically stated, the hood of the present invention, which, overall, has a generally dome-like configuration of any conventional shape used in the art, is divided along a substantially central, vertical plane into two sections, 10 and 12, each approximating in shape and form a hollow, spherical quadrant. Each of the sections 10 and 12 is formed with an inner wall, 14, and outer wall, 16, spaced from the inner wall and somewhat larger than the inner wall, so that the bottom edges of the inner and outer walls 14 and 16 lie in a plane substantially perpendicular to the plane in which the vertically-disposed edges, 18 and 20, of these sections lie.
The space between the vertically-disposed edges 18 and 20 of the walls 14 and 16 is preferably left open, whereas the space between the bottom edges of the walls 13 and 16 is closed off; such closure preferably also serving to space and maintain the two walls of each section in spaced relation. In the illustrated embodiment of the invention, this double purpose is shown to be efifected by means of a relatively wide flange, 22, extending outwardly from the bottom edge of the inner wall 14 and a relatively narrow flange, 24, extending outwardly from the bottom edge of the outer wall, 16; the flange 24 being superposed upon and secured edge-to-edge, to the flange 22, as by means of bolts, 26.
The walls 14 and 16 of the hood sections 10 and 12 are preferably formed of a light weight transparent synthetic plastic material, to give the user of the hood a sense of lightness and lack of a sense of confinement, and also to afford the user the ability to examine her hair, in the course of drying, by the use of a reflecting mirror. As the space between the walls 14 and 16 is intended for the passage of heated air to the hair, the inner wall 14 is formed with a plurality of spaced holes, 28, through which blown air is distributed over the hair.
Each of the hood sections .10 and 12 is pivotally supported at one end in a manner to be spread apart at the other end, for receiving a head between them and for being moved together about the head to form a complete, operative hood. Each of the hood sections 10 and 12 is also provided with conduit means to connect the space between its inner and outer walls with a source of driven air. While the pivotal mounting means and the air conduit means into the hood sections may be of any desired suitable type and made structurally distinct from one another, it is preferable to have the air conduit means also serve as a pivotal mounting means for the hood sections. One such arrangement is illustrated in the drawings, wherein the rear end portion of the outer wall 16 of each of sections 10 and 12 is formed with a cut-out sec tion, 30, in register with the cut-out section of the other of the hood sections, so that when the hood sections are in juxtaposed position the cut-outs 30 form a unitary opening.
A channel member forming a hemi-conduit is secured by one end to each of the hood sections 10 and 12 around the opening portion 30 formed therein with the opening in the channel means of each hood section facing the opening of the channel member in the other section, and with their longitudinal edges in register so that when the two hood sections are juxtaposed, the edges of the channel members are likewise juxtaposed to form a complete conduit. Thus, hood section 10 is provided with a chan- 3 ml member, 32, having side walls, 34 and 36, and a connecting wall, 38, is conneptecl, :as by flange, 40, at one end thereof, to the outer wall 16 of section 10, the free end portion ofchannelrnember 32 being of rectangular crosssection, with the side walls 34 and 36 parallel and hori* zontal. Likewise, a channel member, 42, having side Walls, 44 and 46, and a connecting Wall, 48, is connected by a flange or flare, 50, at one end thereof, to the wall 16 of the hood section 12, the outer end of channel mem ber 42 being of substantially rectangular cross-section with its side walls 44 and 46 parallel andhorizont-al; Preferably, the channel members or hei'ni conduits 32 and 42 are formed of metal and their free ends of their respective top and bottom walls 34 and 36 and 44 and 46 are cut away at an angle to their longitudinal edges for a distance near their free ends to taper such walls.
The helm-conduits 32 and 42 are each pivotally supported on the end of a conduit, generally designated as 54, preferably formed of metal, which maybe connected or c-onnectable directly to a source of blown heated air, or may be telescopically connected to a second conduit, with the latter connected to a source of blown heated air, in a manner that is well known in the art and does not constitute any part of the present invention and is, therefore, not specific-ally illustrated in the drawings.
Preferably, the conduit 54 is of L-shape, and the hemiconduits 32 and 42 are mounted on one of the conduit legs, 56, at least the end portion of which is of rectangular shape and of a size to snugly accommodate therewithin the ends of the two hemi-conduits 32 and 42, when they are juxtaposed edge to edge.
In order to provide a firm pivot between the conduit leg 56 and the hemi-conduits 32 and 42, the top and bottom walls of the conduit leg 56 are formed with extensions, 58 and 60, respectively, which are slightly offset outwardly from their base walls and lie in planes parallel to one another and to the walls from which they extend. Each of the extensions 58 and 60 is provided with a circular pivot opening, 62, that centers on an extension of the longitudinal center line of their connected conduit wall, and at a distance from the end of the conduit leg less than the length of the tapered end portions of the herni-conduits 32 and 42.
In order to provide a steady and rigid pivot of the hemi-conduits on the conduit leg 56, so as to avoid vertical displacement of the hood sections and 12, relative to one another, a washer is secured to the top and bottom wall of each of the hemi-conduits 32 and 42. These washers are preferably round and center on the apex formed between the longitudinal edge of each wall and the edge of the cut-away portion thereof; the washers secured to the top and bottom walls of one of the hemiconduits being secured to different faces of such walls than the washers secured on the corresponding walls of the other hemi-conduit. Thus, in the illustrated embodiment of FIG. 8, washers 64 are secured to the top face of walls 34 and 36 of hemi-conduit 32; whereas washers 66 are secured to the under face of walls. 44 and 46, respectively, of conduit 42. By this arrangement, when the hemi-conduits 32 and 42 are juxtaposed, the top and bottom washers 'of each overlap the top and bottom walls of the other and do not interfere with the juxtapositioning.
A round pivot hole, 68, is formed in each of walls 34 and 36 of hemi-conduit 32, centering on the apex formed between the longitudinal edge of each of said walls and the edge of the cut-away portion thereof; such opening 68 extending through the respective washers 64 and lying only partly in the wall. Similarly, a pivot opening, 70, is formed in each of walls 44 and 46 of hemiconduit 42, centering on the apex of said wall formed by its longitudinal edge and by the edges of its tapered portion. Holes, 64, 66 and 68 and 70 are preferably equal in size to one another. It will be apparent that when hemi-conduits 32 and 42 are placed edge to edge and in longitudinal regis- 'ter, the openings 64 and 66 will overlap and register, and
4 that, when in such position, these registering openings are brought into register with the openings 68 and 70, the ends of the hemi-c'onduits will extend into the end of the end of the conduit leg 56.
When in the last described position, the hemi-conduits 32 and 42 may be pivotally assembled with the conduit extensions 58 and 60 by means, preferably, of eyelets as 72, that may be inserted through each of openings 62 in the extensions 58'and 68 and through the registering openings 68 and 'ififorrned in the washers 64 and 66, respectively, attached to the top and bottom walls of hemiconduits 32 and 42, respectively. The ends of the eyelets 72 may be held in place by swaging, in the conventional manner. I M
It will be apparent that the hemi-conduits 32 and 42 may be rotated on the pivot 72 into divergent position, as made possible by the cut-away ends of walls 34 and 36 and 44 and 46; the angle of the cut-away portions determining the extent of divergence, to thereby spread the two hood sections 16 and 12 apart sufficiently to be fitted around a head. It Will also be apparent that the two hemi-conduits 32 and 42 may be moved into edge-ta edge position to thereby bring the edges of the hood sec tions 10 and 12 together to form a complete, head-em closing hood and at the same time forming a complete conduit connecting the space between the hood walls with the conduit 54 for direct blown air from conduit 43 into the said space.
If desired, means may be provided to inhibit leakage of air between the juxtaposed edges of the hood sections. While various means may be provided for the purpose, one means has been illustrated in the drawings, consisting of a U-shaped gasket, 74, formed of a resilient material such as rubber, which may be fitted on the edge of the outer wall 16 of a hood section, as 10, as shown in FIGS. 6 and 7 of the drawings.
Means may be provided for normally urging the two hood sections 10 and 12 into juxtaposed position. Such means may comprise a bolt, 76, extended inwardly and through opening 62 of extensions 58 and 60 of the conduit 54, and through registering openings 68 and 70 of the hemi-conduits 32 and 42. The bolt 76 mounts a torsion spring, 78, on its projecting end, the spring ends pressing against the upright walls 38 and 48, respectively, of said hemi-conduits 32 and 42, adjacent their ends, to thereby press the portions of the hemi-conduits to the other side of the pivot towards one another. A lock-nut, 80, is engaged upon the threaded end of the bolt 76 to maintain it and the spring in position.
Additional means may be provided for maintaining the free ends of the hood sections 10 and 12 in closed position and also in vertical alinement. Such means may comprise magnets, 82 and 84, positioned respectively in hood sections 10 and 12 adjacent their edges 18 and 19, preferably resting between the walls 14 and 16 of each upon the flange 22. The magnets 82 and 84 may be secured in place in any suitable manner with opposite poles facing and in horizontal alinement, whereby the magnets will tend to attract .one another when the hood is closed, and to adjust themselves in axial alinement, to thereby, both, maintain the free ends of the hood sections 10 and 12 in juxtaposed position, as well as in vertically alined relation.
This completes the description of the hair dryer hood of the present invention. It will be readily apparent that such hair dryer hood provides increased comfort and convenience to the user by facilitating the fitting thereof about and removal of the same from the head; that it is light weight and transparent, to thereby make it addi tionally confiortable for the use by eliminating any sense of confinement as well as easing any contact of the parts with the head. It will also be apparent that the hair dryer hood of the present invention is convenient to use and highly suitable and efiicient for its purposes.
It will likewise be apparent that the hair dryer hood of the present invention is of relatively simple construction and relatively easy and economical to construct and assemble and highly suitable for utilization in noncommercial as well as commercial hair dryer installations.
It will further be apparent that numerous modifications and variations of the hair dryer hood of the present invention may be made by anyone skilled in the art, in accordance with the principles of the invention hereinabove set forth, and without the exercise of any inventive ingenuity. I desire, therefore, to be protected for any and all such modifications and variations that may be made within the spirit of the invention and the scope of the claims hereto appended.
