Abstract

The invention relates to a rotatable attachment (3) for a hairstyling apparatus (1) for styling hair, in particular for forming curls or waves, having at least two finger-like projections (8, 8') for winding the hair to be styled, wherein the projections (8, 8') define a strand guiding channel (9) running therebetween and have rounded hair contact surfaces (10, 10'). Essential to the invention is that at least the hair contact surfaces (10, 10') of the projections (8, 8') are designed so that introduction of curls when hair strands are placed is possible independently of the rotation direction (11) of the attachment (3) without kinks occurring in the hair. According to the invention, handling in particular of the hairstyling apparatus can be thus simplified.

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 article for a

Hair shaping device known with a total of four finger-like extensions for winding the hair to be formed. These extensions define a running between these strand guide channel and also have rounded

Hair conditioning surfaces on. With the known from the prior art

Hair shaping device should in particular those associated with the

Use of a curling shear occurring disadvantages, such as, a high

Temperature load on the hair, to be avoided.

A disadvantage of the known prior art, however, is that the attachment for the

Hair shaping device can be used due to the attachment geometry for only a defined direction of rotation, so that for changing between standing or falling curls and to change the head side is always a cumbersome and laborious grasping and repositioning of the hair shaping device is required. If there is no gripping or repositioning of the hair-shaping device, kinks in the hair can occur due to the rotational direction-dependent geometry of the attachment, which have a significantly negative effect on the hairdressing result. 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, as otherwise also to a negative impact on the

Overall hairstyle can come.

The present invention therefore deals with the problem of providing for an essay and an associated hair styling an improved 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 of geometrically changing a known rotatable attachment for a hair styling device so that both standing and falling curls or waves can be generated by a simple reversal of the direction of rotation without the risk of that due to unsuitable radii within the essay the hair to be curled or curled is kinked. For this purpose, the rotatable attachment two

finger-like projections for winding up the hair to be formed, this

Fortsätze define an interposed Strähnenführungskanal and at the same time have rounded hair contact surfaces. In order to realize the usability of the attachment in both directions of rotation, the rotatable attachment has movable elements relative to the extensions which form at least part of the strand guide channel and / or constitute a cylindrical outer surface on which the hair to be curled or corrugated rest can. The finger-like extensions and the associated movable elements thereby form geometric curves whose radii are so large that a bending of the hair when rolling around this radius can be excluded. The basic geometry of the attachment is cylindrical, wherein the two extensions each form a substantially oval cross-section. Enveloping the two extensions, the two movable elements are arranged, which are formed in this case as two non-contacting half-shells. Between the two half shells remains a gap, which has a cross section of the

Forming strand guide channels. When turning the essay while the hair of the threaded strand press the movable elements in a position that causes the hair from the strand guide channel over a large radius, ie over a radius of no hair damage, such as, kinks, on the outer periphery of the essay sets. The mobility of the movable elements is independent of the direction of rotation, which can be ensured that the hair strands can be rolled up either right or left around, without thereby the Frisierergebnis is negatively affected. The direction of rotation of the attachment is further achieved in that in each case at an input and at an exit of the strand guide channel with respect to an outer circumferential surface of the cylindrical attachment in each case such a large Radius is provided, which do not lead to damage of the hair during the course of the hair styling process, eg. The rolling, heating, cooling and unwinding. Another effect of this half-shell-like movable elements is the most extensive preservation of the circular circumference of the essay around which the hair is wound. The total of four radii at the entrance or exit of

Strähnenführungskanals can either be the same or different in size. In general, an essay with rotatably connected to a handle extensions and rotatable elements is conceivable, as well as an essay with rotatably connected to the handle movable elements and rotatably mounted to the handle extensions, so that under the term used in the patent application "movable elements" always only one possibility of movement of the elements is to be understood relative to the extensions, regardless of whether the movable elements are rotatable relative to the handle or rotatably connected to this .. In an embodiment in which no motorized rotary drive of the essay, this can also be rotated manually be, in which case the movable elements would be rotatable relative to the extensions and the handle.

In an advantageous embodiment of the solution according to the invention, the movable elements have a membrane-like or chain-like structure, which is connected to one end of one of the extensions and other ends with one of the half-shells.

These membrane or chain-like structures form part of the strand guide channel running within the attachment and, because of their flexible structure, can easily be adapted to different circumstances. Depending on the selected direction of rotation of the essay, the chain or membrane-like structures are applied to the attachments and form in this state a hair contact surface or press in opposite direction of rotation, the strands against the opposite extension and thus cause the system of strands of the opposite extension.

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 not only in the combination specified, 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:

Fig. 2 is a sectional view through a possible embodiments of a

inventive essay for the illustrated in FIG. 1

Hair shaping device, Fig. 3 shows another possible embodiment of an article,

Fig. 4 is a representation as in Fig. 3, but in a further alternative of the essay.

According to FIG. 1, a hair styling device 1 according to the invention has a handle 2 and a rotatable attachment 3 for shaping hair, in particular for curls or waves. The essay 3 is in the shown

Embodiment rotatably connected to a drive shaft 4, which in turn in turn rotatably connected to a drive device in the handle 2, for example. An electric motor, is connected. The electric motor can be switched on or off by means of a switch 5 and in particular controlled in terms of its speed.

At the handle end, the hair styling device 1 according to FIG. 1 a

Connection element 6, via which the hair styling device 1 is connectable to an electrical network. In addition, a battery 7 may be provided in the handle 2, which is rechargeable via the connection element 6 and the electrical network, not shown, and for a wireless operation of the hair styling device 1 energy for

Provides. 1, the rotatable attachment 3 has two finger-like extensions 8 and 8 ', between which a strand guide channel 9 runs. Surrounding the two finger-like extensions 8 and 8 'substantially in the manner of a half shell, movable elements 10 and 10' are arranged on the top 3, which form at least part of the strand guide channel 9 and a cylindrical outer lateral surface (compare FIGS. 2 and 3). In an embodiment not shown, in which no motorized rotary drive of the attachment 3 takes place, this can also be rotated manually, in which case the electric motor is eliminated and then the movable elements 10, 10 'relative to the extensions 8,8' and the handle 2 would be rotatable. In general, it is an essay 3 with rotatably connected to the handle 2 extensions 8,8 'and rotatable elements 10, 10' conceivable, as well as an essay 3 with rotatably connected to the handle 2 movable elements 10, 10 'and rotatable to the handle second stored appendages 8,8 ', so that under the term

"Movable" elements 10, 10 'is always a possibility of movement of the elements 10, 10' relative to the extensions 8,8 'to be understood, regardless of whether the movable elements 10, 10' actually rotatable relative to the handle 2 or rotatable with connected to this.

Looking at Fig. 2, left side, it can be seen that the two

finger-like projections 8 and 8 'each have an oval cross section and of the two are not touching and designed as half shells, movable elements

10 and 10 'are wrapped. Now, if a strand of hair 1 1 inserted into the strand guide channel 9 and simultaneously the switch 5 is actuated, then the attachment 3 rotates, at the same time a relative rotation of the movable elements 10 and 10 'takes place relative to the extensions 8 and 8' (see FIG. 2, right side). This causes the strand of hair

1 1 to a hair contact surface 12 and 12 'of the respective extension 8 and 8' is pressed and thereby corrugated. As can be clearly seen in FIG. 2, such a wave also functions when the direction of rotation of the attachment 3 is reversed.

Looking at Fig. 3, it can be seen that on the movable elements 10 and 10 ', a membrane or chain-like structure 13, 13' is arranged, which has an end with one of the extensions 8,8 'and other ends with a the trained as half-shells, movable elements 10, 10 'is connected.

In the attachment 3 according to FIG. 4, the two extensions 8 and 8 'each have a semicircular cross-section, wherein the movable elements 10,10' in this case as in the strand guide channel 9 protruding flaps 14, 14 'are formed and each articulated to one of the extensions 8,8' are arranged. Also by this training, a rolling of the hair 1 1 can be achieved by a comparatively large radius during operation of the hair styling device 1, which in particular the hair style result disturbing hair bends can be reliably avoided. In order to simplify threading the strands of hair 1 1 into the strand guide channel 9, at least one of the extensions 8, 8 'can have a notch or taper at its free end, as shown, for example, according to FIG. 1. In addition, at least one of the extensions 8, 8 'can also be designed to be heatable and / or coolable, and as a result, due to the temperature which can be introduced into the hair 11, the shaping process can be favorably influenced. For heating or for cooling, a so-called Peltier element can be provided in at least one of the extensions 8, 8 ', which at least the

Hair conditioning surfaces 12, 12 'or even the entire extension 8,8' heated or cooled. Alternatively, a channel structure arranged in the respective extension 8, 8 'may be provided, through which warm or cool air can be conducted and delivered to the hair via corresponding air outlets. Of course, it is also conceivable that through this channel-like structure or the air outlets additionally or alternatively a liquid, for example. A hair care product is transferred to the hair 1 1.

Both at an entrance and at an exit of the strand guide channel 9, the rounded trained hair contact surfaces 12, 12 'are provided, whose radius is preferably the same size and thereby allow easy generation of standing or falling curls by a simple reversal of rotation of the attachment 3. The trained between the two extensions 8 and 8 '

Strähnenführungskanal 9 can of course have a rectilinear or a wave-like course. The cross section and thus also the radius of the extensions 8,8 'can of course vary in the axial direction 15 of the attachment 3 and in particular taper towards the free end of the attachment 3.

In general, the article 3 can be handled extremely variable, for example. Like a conventional hair curlers and thus longer time remain in the hair to be curled or wavy. The hair styling device 1 according to the invention has the great advantage that the attachment 3 can be used with any direction of rotation when rolling up the strands of hair 1 1, without negatively affecting the result of the hairstyle influence. By using the movable elements 10,10 ', the

Hair strand 1 1 similar to a conventional curling iron, use a largely circular cross-section. Another advantage especially in one

Embodiment with two extensions 8,8 'is the avoidance of a faulty threading, since there is only one possibility for the strand of hair 1 1 to be positioned within the attachment 3. Of course, different attachments 3 can be connected to the drive shaft 4, so that depending on the desired curl size individual attachments 3 can be used.

The attachment 3 shown has, according to FIGS. 2 to 4, a substantially circular cross-section with internal extensions 8 and 8 '. It is conceivable, however

Of course, a different cross-sectional shape, such as an ellipse, a super ellipse, a slot shape, and ellipse-like shapes whose radii differ on the short and / or long sides compared to a normal ellipse. The strand guide channel 9 preferably runs along a main axis, but generally also any channel guidance is possible.
