Description

Attachment for a hair styling device

The present invention relates to a rotatable attachment for a

Hair shaping device for shaping hair, in particular for curling or wave formation, according to the preamble of claim 1. The invention also relates to a hair shaping device equipped with such a rotatable attachment.

From WO 2008/028941 A2 is a generic rotatable attachment for a

Hair shaping device known, which has a total of four finger-like extensions for winding the hair to be formed, said extensions define a running between them strand guide channel and rounded

Have hair conditioning surfaces. The rotatable attachment is on one

Hair shaping device attachable and drivable by this. With the said hair styling device, in particular, the high loads occurring in the use of known from the prior art curling irons and

Dangers are avoided.

A disadvantage of known from the prior art hair styling devices and rotatable attachments, however, is that care must be taken that the

Hair strands need to be rolled up in a preferred direction, as it may otherwise come to selectively kink-like structures that adversely affect the subsequent Frisierergebnis. There is thus a defined direction of rotation, so that to change between standing or falling curls and to change the head side is always a cumbersome and laborious grasping and repositioning the

Hair shaping device is required. Furthermore, care must be taken in the known from the prior art essay that the hair strands are threaded within the essay in the correct strand guide channel, otherwise it can also lead to a negative impact on the overall result of the hairstyle.

The present invention therefore deals with the problem of providing a rotary attachment or a hair styling device of the generic type, an improved or at least one alternative embodiment, which is characterized in particular by a significantly simplified handling. This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.

The present invention is based on the general idea, a rotatable attachment for a hair styling device for shaping hair, especially for curling or wave formation, such that this the desired curls or waves independent of direction of rotation, that is, right- or left-handed, in the same quality generated, so that, for example, standing or falling curls without a

Implementing the essay in the hair can be generated by only a reversal of direction. For this purpose, the rotatable attachment according to the invention has at least two finger-like extensions for winding up the hair to be formed, said extensions defining a strand guide channel extending therebetween and at the same time having rounded hair contact surfaces. According to the invention, at least these hair contact surfaces of the projections are designed such that when hair strands are inserted it is possible to introduce curls or waves independently of the direction of rotation of the attachment, without kinks occurring in the hair. In the known from the prior art essays leads a

Direction of rotation reversal of the essay due to unsuitable, that is in particular too small, radii on the hair contact surfaces to the fact that kink-like structures are introduced into the hair to be curled or wavy, whereby the Frisierergebnis is adversely affected overall. By contrast, with the attachment according to the invention, it is possible to roll up the threaded hair strands either right-handed or left-handed, whereby the rotation direction independence of the attachment is achieved by radii being present on both sides of the ends of the strand guide channel which, during the course of the hairstyling process (for example rolling up) heating, cooling and unwinding, not damaging the hair,

lead in particular by an extreme geometric stress. With the article according to the invention, the handling and use of a hair-shaping device, for example a curling iron, is thus considerably simplified, since both standing and falling curls can be produced without difficulty by simply reversing the direction of rotation of the article. With the

According to the article of the invention, it is surprisingly possible to use only one geometrical adaptation of the radii of the hair contact surfaces form the attachment in such a way that it can be used independently of the direction of rotation.

In an advantageous development of the solution according to the invention, at least one of the projections is designed to be heatable and / or coolable. A heating of at least one of the projections can be effected for example by a heating element arranged in the respective extension, for example a Peltier element, or else by a

Passing hot air through the extension, wherein the extension in this case has a channel-like internal structure, which allows a release of hot air to the hair through a plurality of small outlet openings and thereby the

Curling process favored. Of course, it is also conceivable that the at least one extension is coolable, wherein the cooling in turn

can be done for example by means of a Peltier element, or by

Passing cool air through the channel-like structure. The cooling can thus be effected, for example, by a cold (for example room temperature) air flow or else optionally by other gaseous or liquid media, in which case, for example, a reservoir and / or supply lines would be required. About this reservoir or supply lines and then the delivery of a hair care product, such as a setting, to the hair during the curling process would be possible. The invention is further based on the general idea of equipping a hair styling device known per se, for example a curling iron, with such an article according to the invention, it being understood that very different attachments can be combined with the hair styling device. The

Hair shaping device also has a handle for holding the same and preferably a motorized rotary drive for the essay on. It is conceivable, in particular, to offer such a hair shaping device in a set which has a plurality of differently designed attachments, as well as the actual ones

Hair styling device comprises. Other important features and advantages of the invention will become apparent from the

Subclaims, from the drawings and from the associated description of the figures with reference to the drawings. It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention. Preferred embodiments of the invention are illustrated in the drawings and will be explained in more detail in the following description, wherein the same

Refers to reference to the same or similar or functionally identical components.

In each case show schematically:

1 shows a hair shaping device according to the invention,

Fig. 2-4 cross-sectional views of differently designed essays for a

Hair styling device according to Fig. 1,

5 and 6 an essay with yin and yang-shaped extensions.

According to FIG. 1, a hair shaping device 1 according to the invention for shaping hair, in particular for curling or wave formation, has a grip part 2 and a rotatable attachment 3 connected thereto. The rotatable attachment 3 is rotatably connected via a drive shaft 4 with a arranged in the handle 2 drive device, such as an electric motor. The attachment 3 is designed to be detachable from the drive shaft 4, so that the hair-shaping device 1 can generally be operated with a wide variety of attachments 3. At the same time, a switch 5 for turning on and off the hair styling device 1, in particular its electric motor, is provided on the handle 2, as well as a connecting element 6, via which the

Hair shaping device 1 can be connected to an electrical network. For ease of handling and in particular to a wireless operation, the hair styling device 1 according to the invention on a battery 7, which by

Connection to the electrical network via the connection element 6 can be charged. According to the invention, the attachment 3 now has at least two finger-like projections 8 and 8 ', as shown in FIG. 4, even three finger-like projections 8, 8' and 8 ", which serve to wind up the hairs to be formed and define a strand guide channel 9 running between them. In addition, the extensions 8, 8 'and 8 "rounded hair contact surfaces 10, 10', which are designed such that when inserted into the strand guide channel 9 hair strands 13 is an introduction of curls regardless of the direction of rotation 1 1 of the article 3 is possible without the risk that unwanted kinks are introduced into the hair. The attachment is preferably designed cylindrical and has according to Figures 1-3 two extensions 8, 8 ', wherein according to the Fig. 2 between the two extensions 8 and 8' a straight and according to the Fig. 3, a wave-like strand guide channel 9 extends. It is also conceivable, however, a curved course. In this case, preferably both the inner radii within the strand guide channel 9 and the radii of the hair contact surfaces 10, 10 'and the outer radii of the extensions 8, 8' and 8 "coordinated so that the hair strands 13 along the outer surface no longer straight distances cover which then have a negative impact on that

Hairdressing result. At the same time the strand guide channel 9 is formed in the interior of the article 3 with a certain width, which ensures easy threading and detachment of the hair strand to be lured or to be selected. The radii R, R 'at an input or output of the strand guide channel 9 can be configured identical or different from each other. At the same time, the radii R, R 'of the hair contact surfaces 10, 10' in the axial direction 12 of the extensions 8, 8 ', 8 "vary.

According to FIG. 4, the attachment 3 designed according to the invention has a total of three extensions 8, 8 'and 8 ", each having a lens-like cross-section.

Looking at Figures 5 and 6, it can be seen that here the essay 3 each have two yin and yang-shaped extensions 8, 8 '. Ideally, in this case, the rolling of the hair strand 13 should take place over the large radius R, wherein in particular according to FIG. 6, the yin and yang-shaped projections 8, 8 'may be formed with respect to their small radius R' that a

Direction independent use of the essay 3 is possible. Yin and yang-like structures play a major role in the wellness movement, which is why alone by such trained extensions 8, 8 'a promotional factor can be obtained. Of course, yin-yang-like geometries are conceivable which have more than two extensions 8, 8 '.

In order to facilitate a threading of the hair in the strand guide channel 9, a notch is provided on at least one of the extensions 8, 8 'at its free end or else these are formed tapering towards the free end.

Furthermore, the curl or wave formation can be assisted by the fact that at least one of the extensions 8, 8 ', 8 "is designed to be heatable and / or coolable. Heating or cooling of the hair strands can be effected by a heating element acting directly on it or cooling element, for example a Peltier element, or by a corresponding air flow, wherein in the latter case within at least one extension 8, 8 ', 8 "a channel structure is arranged, through which warm / cool air conductive and can be delivered to the hair. Alternatively, it is also conceivable for the extensions 8, 8 ', 8 "to be formed from a solid material and to be heatable as such Optionally, the attachment 3 can also be provided with the possibility of active cooling, which is achieved for example by gaseous or liquid media. which are transferred to the hair via the channel structure, in which case a reservoir should be provided in particular for liquid media.

In general, while the essay 3 can be used extremely flexible, it can, for example, like a conventional hair curlers remain in the hair for a long time or similar to a styling brush are used, with only one threading, twisting, heating, cooling and pulling out of the hair done. Also, the radii R, R 'different essays can be different sizes, whereby the curl size can be influenced individually. Of course, an equal influence is also possible on the temperature to be transferred to the hair during the curling process. The attachment 3 shown here has a substantially circular cross-section with the two extensions 8 and 8 '. Of course, it is also conceivable, however, a different cross-sectional shape, such as an ellipse, a super ellipse, a slot shape, as well as ellipse-like shapes whose radii on the short and / or long sides differ in comparison to a normal ellipse. Of the

Strähnenführungskanal 9 preferably runs along a major axis, but generally also any channel management is possible.

With the inventive article 3 and the invention

Hair styling device 1, the decisive advantage can be realized that an introduction of curls or waves in the hair is independent of direction of rotation possible without this a negative impact, for example, by a buckling of the hair, must be feared. At the same time, especially in the variant with two extensions 8, 8 'and only a single strand guide channel 9, a faulty threading can be avoided, whereby the handling of the hair shaping device 1 according to the invention is facilitated.
