Abstract

The device comprises in a housing (11) three rotatable cylinders (15, 19, 20) provided with inter-locking gear-mesh (16, 21, 22) rigidly attached to each of these, means for rotating one of the cylinders, which results via said gear in simultaneous rotation in opposite sense of the adjacent cylinder. Each of the cylinder is provided, at one of its ends with a cylindrical member (17, 25, 26) protruding externally the housing; each of said cylindrical members is provided closed to its exposed end with an O-ring (18, 23, 24), the said cylindrical members being disposed so that said O-rings are either in contact or in very closed proximity so that said O-rings are adapted to pull out hairs which come into contact with them.

Description

DEVICE FOR REMOVING HAIRS

The invention relates to a novel device for the removal of hairs. It is based on the gripping of the hairs by rotating members,, which are in contact with each other, and by the pulling out of the hairs.

The device is of simple and inexpensive construction and can be easily mass-produced.

The removal of hairs is very wide-spread, especially amongst women. The most frequently "treated" areas are the arms and legs.

There exist a wide variety of preparations of different nature, such as various waxes for pulling out the hairs, and mechanical devices.

The drawback is that the use of most of these causes pain and is not too effective. Shaving is unacceptable as there remains a residue of shaved-off hairs which grow again at a fast rate.

There exist also some mechanical devices which have gained a high degree of success, such as those based on a rotating spi ra I .

The present invention provides a simple, reliable device which is convenient in use, causes a minimum of pain and is very effective in the removal of hair.

The invention relates to a device for the removal of hairs, especially from arms and legs, and from other parts of the human body, which comprises at least two rotatable cylinders provided with inter-locking gear-mesh rigidly attached to each of these, means for rotating one of the cylinders, which results via said gear in the simultaneous rotation of the adjacent cylinder (in opposite sense of rotation), said cylinders being provided at one of their ends, with a cylindrical member protruding externally the housing, each of said cylindrical members being provided close to its exposed end with an O-ring, the said cylindrical members being disposed so that said O-rings are either in contact or in very close proximity, said rotating O-rings being adapted to pull out hairs which come into contact with them, the cylindrical members being held in an at least approximately perpendicular relationship to the skin.

According to a preferred embodiment of the invention, the device comprises three rotating cylindrical members each of which is provided with intermeshirg toothed wheels, said wheels forming an inter eshing gear, a smalt electrical motor driving one of the said cylindrical members, each of the cylindrical members being provided at its upper end with an O-ring, said O-rings being in contact during rotation, and thus being adapted to pull out hairs engaged by them.

Due to the mesh-gear rigidly attached to each of the cylindrical members, all three cylinders are positively driven by the rotating cylinder powered by the motor.

The cylindrical members, parallel with each other, and provided with an O-ring at their upper ends, can be arranged on the same line. They can also be at a certain angle ith each other.

The rotating cylindrical members are generally driven by the rotating motor by an axial drive. It is also possible to resort to a certain small degree of excentricity of the drive, where the axis of rotation is offset respective the axis of the cylinder by a small di stance.

According to a preferred embodiment, the motor drives one of the cylinders, which is provided with a rigidly attached toothed wheel, the other cylinders being of similar arrangement, with the gears on each of these intermeshing with that of the adjacent cylinder, there being provided on each of the cylinders a member with circular cross-section, of larger diameter, each of these being provided with an O-ring at its upper end. The invention is illustrated with reference to the enclosed schematical drawings, which are not according to scale and in which:

Fig. 1 is a side-view, in partial section of a device of the invention.

Fig. 2 is a sectional view of part of the device of Fig. 1, according to line II-II of figure 3.

Fig. 3 is a schematical view illustrating the relation of the intermeshing gear on the three cylinders.

Fig. 4 illustrates a drive of the cylindrical members which is excentric.

Fig. 5 illustrates schematically the relation of the O-rings in a device with excentric drive.

As illustrated in Figure 1, the device of the invention comprises a housing 11, in which there is provided a small electric motor 12, connected by connector 13, via its rotating shaft 14, to a rotatable cylinder 15, to which there is rigidly attached a toothed wheel 16 and a cylindrical member 17 which protrudes beyond the upper end of the housing 11, and close to the upper end of which there is provided an O-ring 18. The device comprises two further cylindrical members 19 and 20, provided respectively with gear 21 and 22, and O-rings 23 and 24 on members 25 and 26.

The cylinders rotate in a suitable inner housing

27, and at their ends there are provided locking members

28, 29 and 30, respectively.

Figure 2 illustrates the housing 11, the inner support-housing 27, a side-view of the cylinder 15, with the gear 16 attached at its upper end, with 0-ring 18.

Figure 3 illustrates the intermeshing 0-rings 18, 23 and 24.

The electrical motor is actuated by a battery or by an external current source, in this case as illustrated on figure 1, the power is supplied via the electric cord 8.

As shown in Figure 4, according to a further embodiment of the invention, in housing 41 there are provided three cylinders 42, 43 and 44, the central one being driven by a motor, not shown, each of these bearing at their upper ends cylindrical members 45, 46, and 47 bearing O-rings 48, 49 and 50, respectively. The cylinders 42, 43 and 44 are attached to cylinders 45, 46 and 47 in an excentric manner. The three cylinders 42, 43, 44 are provided respectively with gears 51, 52, 53.

When the motor actuates one of the cylindrical members, the others are automatically actuated, rotating in a sense opposite to that of the central one. When passed over a haired body part, the hairs are are engaged by the rotating O-rings and pulled out. The pulling-out is very fast and nearly painless.

Although illustrated with reference to a device with three rotating O-rings, it is clear that also a device with only two such O-rings will work, and that it is possible to use more than three O-rings with respective drive means. When arranged at a certain angle, three rotating members have an even better pull-out effect.

The housing is advantageously provided with a tapering upper part 54 so as to provide better access to the body surface which is being treated. The O-rings are either in contact with each other or in very close proximity, as the diameter of a human hair is very small.

The above description is by way of illustration only, and it is clear that various modifications and changes in the nature and arrangement of parts can be resorted to without departing from the scope and spirit of the invention.
