HAIR-DRYING COMB This invention relates to a hair-drying comb. More specifically, this invention relates to a comb which is adapted to hold the hair in thin, spaced, parallel stacks and to direct drying air toward the stacks from positions inbetween the stacks.
In the past, there have been many drying combs which deliver heated air or other fluid toward the hair. An example is the comb shown in the old U.S. Pat. No. I,l06,4l I wherein heated air is forced through passages in the individual comb teeth to the tips thereof to promote rapid hair drying. Other hand-held devices have included a conventional comb backed by a blower and heater. A number of devices have comprised a comb or brush having a delivery duct to which is supplied heated air through a hose from a portable hairdrying unit.
While a number of aforementioned prior devices represented improvements on the conventional hairdrying device where hot air was blown directly at the surface of the hair, they have always been'objectionable for the length of time it has taken to dry the hair when using them. For instance, a woman having long hair has taken forty minutes to an hour using some of the prior devices.
The present invention has for an object primarily to shorten the length of drying time required. It accomplishes this by improving the coupling between the hair drying fluid and the hair so that the individual hair strands are exposed directly to blasts of warm air while the strands are in a thin stack. The result is a reduction of 30 to 50 percent in the drying time as compared with the time of prior artdevices.
While the present device is much more effective as a hair drying means and sharply reduces the amount of time required to dry hair, it is simple, rugged, and inexpensive to manufacture.
Other objects of the invention will be apparent from the following specification including the drawings wherein:
FIG. 1 shows in use a hair-drying comb embodying the invention;
FIG. 2 is a perspective view of the preferred embodiment of the comb;
FIG. 3 is an enlarged side elevation of a comb embodying the invention with the central portion broken away;
FIG. 4 is an enlarged end view;
FIG. 5 is an enlarged sectional view, the left half of which is taken on the line 5a5a in FIG. 3, and the right half of which is taken on the line 5b5b of FIG. 3;
FIG. 6 is an enlarged sectional view similar to a part of FIG. 3 but showing a portion of the comb in use and indicating the flow of drying air through the thin stacks of hair held by the comb;
FIG. 7 is a fragmentary top view of the lower part of the comb as shown in FIG. 3 with the top removed; and
FIG. 8 is a fragmentary perspective view of the air deflector.
Referring more specifically to the drawings, FIG. 1 shows in use a comb embodying the invention and which is generally designated 10. It is supplied in the version shown through a hose H by heated air from a conventional portable hair dryer unit D. Such a unit includes air moving means such as a fan and a heating element and blows heated drying air through the hose H to the comb 10. It will be noted in the view shown in FIG. 1 that the teeth of the comb 10 are directed upwardly. The comb may also be used with the teeth directed downward provided the hair is held toward the base of the teeth.
FIG. 3 shows that the comb 10 comprises a housing 12 comprising upper half 12a and lower half 12b, is hollow and is provided with a delivery duct 14 to which the hose H may be attached. Along the lower side shown as in FIG. 3, the housing is provided with a rectangular opening covered by a deflector plate 16 having a plurality of individually spaced slots 18 (FIG. 8) and a plurality of bridges 20 between the slots.
A plurality of individual arch-shaped teeth 22 are also provided. In the version shown, the teeth 22 are of V-shape and their ends are attached to the housing in alignment so that they straddle the slots, respectively. It will be noted in FIG. 3 that the individual teeth 22 are aligned with the individual slots 18, and the bridges 20 between the slots are aligned with the spaces between the teeth.
As shown, the teeth are pointed (FIG. 5) and streamlined (FIG. 6) so that strands of hair readily pass between them. The comb is extremely effective at dealing with snarls common in long hair after washing.
The action of the hair dryer when in operation is suggested in FIG. 6. Because the individual teeth 22 are closed at the bottom, the air which blows downwardly from the slots 18 has to move laterally to escape. With the hair held in thin, parallel, closely spaced stacks by the adjacent teeth, air is forced from positions inbetween adjacent stacks generally perpendicularly toward the thin stacks causing air to actually pass into the thin stack and effect extremely good drying operation. The effectiveness is enhanced by the breadth of the openings 24 in the teeth 22 (FIG. 5) which holds the hair in the thin stacks for a substantial zone therealong while air is blown toward the stacks simultaneously all along the zone. Of course, this action on the hair progresses along the hair strands as the operator moves the comb outward (FIG. 1).
It should be noted that for uniformity of air supply from one tooth to the next, the end of the comb (FIG. 2) may be tapered as at 26 deflecting air toward the slots 18. If desired or necessary internal baffles may be used inside the hollow housing to further control air flow. To avoid channeling of air to a path of least resistance, the teeth 22a at the ends of the row of teeth may be solid, i.e., with no openings 24.
It should be understood that many variations from the specific arrangement described are envisioned. For instance, the comb may be connected directly to a power handle including a warm-air-producing fan and heater powered by battery or household current.
The comb of the invention is extremely effective in drying and styling hair. It is also remarkably effective in removing snarls. The device is inexpensive, rugged, and easy to produce.
l. A hair-drying comb comprising a hollow housing having a delivery duct and a plurality of individual downwardly facing, closely spaced parallel rectangular elongate slots arranged in a row, a plurality of individual generally V-shaped teeth, the teeth having a closed lower end and an open space above the lower 2. A hair-drying comb as described in claim 1 wherein the housing is closed at one end and the delivery duct is at the other end, and the housing is tapered toward the closed end in the area of the slots.
3. A hair drying comb as described in claim 1 wherein the slots are formed in a rectangular deflector plate comprising an insert in an opening in the housing, the plate having bridges between the slots, respectively.
