Description

[Detailed description of the invention] The present invention is a comb for introducing hair into a dry shaver,
of the type in which the citric acid foil is curved and clamped into the shear head frame and rests elastically by means of a spring-acting support on a citric acid foil which is provided with slit-shaped holes for introducing beard hair. related to things.

Known hair introduction combs of this type (U.S. Pat. No. 2,288,162 and German Patent Application No. 1,533,660) are more effective than curved metal sheets or corner-bent metal sheets. In the thin metal plate, the gaps between the comb teeth are milled in a simple manner so as to communicate with the slit-shaped bristle introduction holes in the adjacent citric acid foil. has been done.

In actual use, a hair introduction comb that is easily formed in this manner does not completely solve the problem of, for example, capturing long unshaved beard hair, raising it straight, and introducing it into the hair introduction hole. can only be filled.

In contrast, the problem of the present invention is to use the hair introduction comb of the type mentioned at the beginning to comb the beard so that the beard hair is accurately guided and to reduce the stress of the forcibly directed hair. It is an object of the present invention to provide an improved method for ensuring that the hairs are always completely introduced into the slits of the citric acid foil.

This invention solves this problem, and the hair introduction comb has 90
The bristle-introducing comb is formed as a plastic body approximately wedge-shaped in cross section with a tip angle smaller than The outline of the back of the comb on the skin side on the outside of the comb extends approximately tangentially to the curved surface of the citric acid foil, and the comb teeth are molded from a plastic body, and the skin side end thereof The comb teeth have a freely protruding rounded projection, and on the sides of the comb teeth in the region of the comb tips are provided with guide webs, which guide webs extend from 50° to 90°. configured to be oriented toward the citric acid foil at an angle between.

As described in claim 2 of the utility model registration, by gradually narrowing the gaps between the comb teeth in the hair introduction direction, it is possible to more conveniently catch and guide the beard hair.

In addition, as stated in paragraph 3 of the claims for utility model registration,
Viewing the support material for the hair introduction comb in the hair introduction direction,
By engaging the hair introduction comb before the tip of the comb that is in contact with the citric acid foil, it is possible to more reliably and closely abut the hair introduction comb against the citric acid foil. .

Next, the configuration of the present invention will be specifically explained with reference to the embodiments shown in the drawings.

The hair introduction comb 1 has a substantially wedge-shaped cross section, is hollowed out from the plastic body, and has a tip angle α smaller than 90°.
(Figure 2).

The hair-introducing comb 1 is fixed to a support member 2 with a spring action, and is in contact with a citric acid foil 4 having a slit 3 for introducing beard hair, the citric acid foil 4 being a conventional comb (not shown). The shear head is curved and tightened into the frame.

The inner surface 5 of the hair-introducing comb 1 rests against the curved surface of the citric acid foil 4, while the outer contour of the comb back 6 extends approximately tangentially to the curved surface of the citric acid foil 4. ing.

The comb teeth 7, which protrude from the plastic body, are provided with projecting rounded projections 8, and on the sides of the comb teeth 7, in the area of the comb tips 9, guide webs 10 are provided. It is oriented at an angle β between 50° and 90° towards the citric acid foil 4.

As can be seen in FIG. 1, the gaps 11 between the comb teeth are formed so as to gradually become narrower in the direction in which the bristles are introduced, that is, approximately in the direction of arrow A.

By configuring the hair introduction comb 1 as described above, the comb back 6 extending tangentially to the curved surface of the citric acid foil 4 is applied to the skin to be shaved, and the hair introduction comb 1 is removed. If you comb the beard in the direction that the protrusion 8 is facing forward and the beard is introduced into the slit 3 of the citric acid foil 4, you can remove long beard hairs that cannot be captured by the small slits 12 of the citric acid foil 4. The long hairs are first captured by the protrusion 8, and as the comb back 6 is moved along the skin, the long hairs are guided to the center through the gaps 11 of the comb teeth, which gradually narrow in the hair introduction direction, and in some cases the guide It is straightened by the web 10 and introduced accurately into the slit 3 of the citric acid foil 4, and is then reliably sheared within this slit 3 by an undercutter (not shown) of a dry shaver. .

Well, the beard hair is especially twisted hair, and the comb teeth are 7.
When the twisted hair is being guided along the side of the comb teeth 7 with strong stress, the hair is forced along the guide web 10 by inevitably hitting the guide web 10. This ensures that the slit 3 is properly raised and introduced into the slit 3.

In other words, the guide web 10 has the function of converting the twisting stress of the beard hair into a raising stress that forces the beard hair into the slit 3 of the citric acid foil 4.

In order to bring the hair introduction comb 1 into close contact with the citric acid foil 4, a support member 2 having a spring action is provided in the hair introduction direction,
That is, in the direction of arrow A, it is engaged with and fixed to the hair introduction comb 1 at a predetermined distance a from the comb tip 9 toward the front.
