The invention relates to a hair styling device for shaping hair, in particular for curling or curling, comprising a handle part and a winder connected thereto with two extensions or extension arrangements for winding up the hair to be formed.

Forming smooth hair into waves or curls, or strengthening natural waves and curls has a long tradition in personal care. In addition to longer-term shaping procedures such as perms are mainly temporary shaping, which are achieved for example by the hair turning on curlers of different shapes and the use of curling irons, popular.

From GB 306,795 and DE 476,028 winder for hair duration waves have become known, each having two winding posts. The winding posts are spaced from each other on a base plate. The hair to be formed is placed around the winding posts several times in the manner of an eight. GB 306,795 also describes that two strands of hair can be formed simultaneously with the two winding posts, one strand of hair starting from one winding post of the eight kind being wound several times around both winding posts and the other strand of hair emanating from the other hair post. These double winder hair is wound up as well as conventional winder and the hair dried with these under heat. The measures are often supported by chemical aids, for example substances for increasing the bounce of the hair and / or shaping gels or waxes.

The known devices for shaping curls have various disadvantages. On the one hand, turning the hair on hair curlers is laborious and time-consuming, and it takes practice to achieve a satisfying result. Furthermore, known devices are characterized in that the hair is rolled from the tips, so that the curl at the top is the strongest, while becoming weaker toward the approach, with the result that the hair is quickly flattened at the base while the tips are very curly or even curly. With longer-term fixation of the curls, for example with perms, it is added that the hair is stressed by the action of the chemicals or even damaged.

Curling irons are known in various embodiments, for example with air outlets for hot air or with heating elements in the area where the hair is wrapped around the rod, with various partially rotatable and / or driven brush attachments and with folding mechanisms to fix the hair to the curling iron. until the molding process is completed.

For example, from the utility model DE 78 07 312 U1 a curling iron is known, which is detachably mounted on the outlet of a hair dryer serving for drying hot air blower and this has a slip-on sleeve with a stepped tubular approach with a plurality of longitudinal slots on the axially serving to unscrew the hair roller brush is releasably attachable. The tubular part has openings, which are penetrated by the bristles of the roller brush.

Furthermore, from EP 1 382 270 A2 a curling iron is known, which has a first arm with a lower surface and a second arm with an upper surface, wherein the surfaces correspond to each other and concave or convex are formed adjacent to each other.

Also EP 1 472 951 A1 discloses a curling iron. This is also pliers-shaped with two arms and has heating elements in or on the arms. Furthermore, a control unit for controlling the up and down movement of the arms, a rotor, with the 3 AT 504 075 B1

Control unit is connected to rotatably support the arms, a fixing member for supporting the rotor, a drive and a switch provided for the drive. The curling iron has safety heating elements, which are attached to the arms.

A disadvantage of the known from the prior art curling irons is in addition to the high burden of hair by the heat of the scissor arms also the high cost of time, energy and costs caused by such devices. On the one hand, the application needs exercise similar to the curlers, until a well-fitting hairstyle can be made reproducible, on the other hand, high-quality devices that protect the hair from excessive heat, expensive to purchase. In addition, due to the high heating power, a power outlet is required, a wireless device can not provide the necessary heat to fix the curls sufficiently. As a result, and also due to the size of the device, for example, driving while traveling is impractical. The locks made by curling irons, like the curls formed by curlers, are strongest at the tips and weakest at the roots, with the above-mentioned disadvantages. In addition, the hair is exposed by winding around the scissor arms of a kink load on the edges of the scissor arms, which can lead to hair breakage in conjunction with the action of heat.

It is therefore an object of the invention to provide a device for shaping the hair in curls or waves, which avoids the disadvantages mentioned and beyond versatile, easy to use, inexpensive to manufacture and gentle to the hair.

This object is achieved by a generic hair styling device mentioned above, in which the extensions or extension arrangements for defining a located between these, extending at its radially outer end portions Strähnenführungsweges for inserting or passing a strand of hair are kept spaced from each other and along the Strähnenführungsweges rounded hair conditioning surfaces exhibit.

This hair styling device comprises two extensions typically extending axially from a base spaced apart from each other, the spacing between the extensions defining at least one strand guide path for inserting or passing a strand of hair which expands at its radial end portions, the extensions Having along the strand guide path rounded hair contact surfaces. The hair strands are introduced from the base of the side facing away from the winder in the strand guide path and the winder then rotated to screw in the hair strand. Through the strand guide path, the strand of hair can be safely placed between the two extensions of the winder.

If the winder is subsequently rotated, the inserted strand of hair lies around the two extensions, so that the strand section accommodated in the winder is curved in an S-shape. In another winding, the hair strand is wrapped with its two, protruding from the winder sections the two extensions wrapping around them. Thus, the envelope of the two extensions then defines the winding geometry.

The spaced apart arrangement of the projections to each other allows easy insertion of a strand of hair in the strand guide path and a simple extraction of the shaped strand of hair after completion of the hair-forming process. Of course, unwinding to release the formed hair from the wrap is also possible. By forming the extensions with rounded hair contact surfaces along the strand guide path, the kinking of hair is reliably avoided. As a result, a simple recording of the strands of hair in the winder and a hair-gentle quick turn on the same even for inexperienced people are possible. 4 AT 504 075 B1

From handling technical advantage is that the strand of hair to be formed is typically detected approximately in the region of its center, being wound by turning the winder, the hair strand from both sides. The winding of a strand of hair therefore requires fewer turns of the winder.

A secure hold in the winder finds the strand of hair, when the strand guide paths are curved in an S-shape, which typically already sets after a first rotation of the winder by a few degrees.

Greatest versatility of the winder according to the invention is achieved by the extensions are formed with the same axial lengths or by the extensions have an axially parallel structure.

In order for the strands of hair to be easily inserted into the strand guide path, it is advantageous if the appendages axially taper at their distal end region remote from the base, or if the appendages are beveled radially outwardly at their free end region remote from the base.

Easy screwing and gentle treatment of the hair are achieved when the projections are circumscribed by an envelope whose profile is circular or elliptical in cross section. This reliably prevents kinks in the hair. For regular insertion of the hair strands, it is also advantageous if the envelope is cylindrical, and more preferably the envelope should approximately coincide with the outline of the base.

In a particularly preferred embodiment of the hair styling device, which is characterized by optimal handling, reliable fit of the hair tresses in the winder and versatility in the application, the winder comprises four extensions, of which two diagonally arranged first extensions have a same cross-sectional shape and two more diagonally to each other arranged second extensions have a same cross-sectional shape, wherein the cross-sectional shape of the first extensions is different from the cross-sectional shape of the second extensions. These two further extensions are to be addressed as auxiliary extensions in this winder. In order to avoid kinking in the hair, in one embodiment of the invention the first extensions have a round or oval cross-section and the second extensions are of a kink-shaped cross section. The round or oval first extensions form the hair contact surfaces.

Excellent insertion of the strands of hair in the winder and the prevention of unintentional generation of kinks of the hair is achieved when the second gore-shaped projections have rounded edges. In this embodiment, the winding direction is clearly defined after inserting a strand of hair in the strand guide path of the winder. As a result, a wrong application and thus possibly associated damage to the hair is avoided.

Advantageously, the winder consists of a dimensionally stable and heat-resistant, in particular up to 180 ° C or 200 ° C heat resistant material. To favor the molding process, it is then possible to heat the extensions to this temperature so that enough heat can be released to form the curls or waves to the hair.

It is also advantageous that the winder can be heated by introducing it into a preheated environment, by introducing it into hot water, by inductive heating or by hot air, which makes the handling simple and safe.

In a preferred embodiment, the winder is detachably connected to the handle part or 5 AT 504 075 B1 connected to this. It is then possible with one and the same handle part to use winder in different sizes and diameters, so that the desired hair shaping according to form both large soft and small firm curls and waves.

Easy and quick handling is achieved when the handle part comprises an electric drive unit with a drive shaft, with which the winder are detachably connectable, wherein preferably the direction of rotation of the drive shaft can be switched.

The handling of the hair styling device is further simplified and accelerated when the drive shaft and the winder via a plug, screw or locking connection, a quick coupling or a bayonet lock are detachably connected to each other.

In a semi-automatic, against incorrect operation largely secured embodiment of the hair styling device according to the invention, the handle part on a sensor which detects a force acting on the drive unit via the winder and the drive shaft pulling force of a wound on the winder hair strand and depending on the detected tensile force, an automatic start of Drive unit triggers or turns off the drive unit.

To avoid exaggerated pull on the hair, the drive unit may have a clutch or slip clutch, which is coupled to the sensor so that the clutch or slip clutch is opened when exceeding a tensile force limit or slips.

To facilitate the formation of strands for the subsequent insertion into the strand guide path of the winder, it is advantageous if the handle part comprises an attachable comb.

It has been shown that the stratification is particularly easy to succeed if the comb consists of two double-curved, crossing each other in a turning point parts. Preferably, for optimum adaptation to the head shape, each of the parts of the comb has a concave profiling of the prongs, so that outer prongs are longer than inner prongs.

The combing of the hair strand is facilitated when the tines are rotatably mounted in brackets, as this measure allows a quick and effective combing and straightening of the hair strands without plucking.

Embodiments of a hair styling device designed according to the invention are shown by way of example in the figures and explained in more detail in the following description. Show it:

1 is a schematic overall view of an inventive device for shaping the hair,

2A-B is a schematic perspective view of an embodiment of a winder for an inventive device according to FIG. 1 for shaping the hair and a schematic plan view from above of the winder according to FIG. 2A, FIG.

3A-C is a highly schematic perspective view and a side view of a suitable for use with the inventively designed device comb and a detail of the comb, and

Fig. 4 shows another embodiment of a winder according to the invention in plan view.

Fig. 1 shows a highly schematic of an embodiment of an inventively designed device 1 for shaping the hair, in particular the human main hair, in curls and / or waves. The device 1 comprises a preferably ergonomically shaped grip part 2, which may contain a drive unit, which is designed, for example, in the form of an electric motor, and a drive shaft 3, which is driven by the drive unit. A winder 4 for detecting and screwing the hair is releasably connected to the drive shaft 3 6 AT 504 075 B1 connectable, for example by plugging, screwing, by a snap-in connection or a bayonet connection. About the drive shaft 3, the winder 4 is driven to rotate and can be used for winding and unrolling individual strands of hair to form a wave or curl, as described in more detail below. The drive unit can be actuated for example by pressing a switch 5. If the strand of hair wound in the desired length, the drive unit can be stopped by a further pressure on the switch 5 again. The switch 5 may also be designed in the form of a switch 5 actuating the drive unit only for the duration of the pressure, so that the drive unit stops after the switch 5 has been released. Furthermore, it is conceivable, the switch 5 in such a way that a switch between clockwise and counterclockwise rotation or a multi-stage adjustment with multiple winding speeds is possible.

A socket 6 in the handle part 2 can serve for the connection of a power supply unit for charging a battery supplying the drive unit with voltage. A battery operation is conceivable, the batteries or removable batteries can be removed from a provided with a cap 7 battery compartment. Likewise, a connection to an AC voltage network is possible, provided that the drive unit is designed accordingly.

Furthermore, the handle part 2 may comprise a sensor which measures the tensile force acting on the hair lock received and pulled into the winder 4 and gives the drive unit a control signal which causes the drive unit to automatically start up in order to completely wind up the hair strand. If the strand is wound up, the tensile force increases to such an extent that the sensor detects the end of the winding process and shuts down the drive unit or a coupling between the drive shaft 3 and the drive unit is released or a slip clutch slips through a tensile force limitation, so that the winding process is terminated without further being able to attack the force exerted by the drive unit pulling force on the hair strand.

However, it is also possible to form the device 1 without a drive unit in order to receive the strands of hair by manually rotating the device 1 and turn the hair strand by turning the grip part 2 which in this case can be rigidly connected to the winder 4. This is a particularly simple and inexpensive embodiment.

To form or stabilize the curls or waves, two conditions must be met. First of all, the shape of the forming part, in this case the winder 4, must be chosen so that waves or curls can be formed, and furthermore heat must be supplied in order to at least temporarily stabilize the shaped hair part.

The first condition is ensured by the cross-sectional shape of the winder 4. 2A and 2B show in a schematic perspective view and in a view from above a winder 4, which is suitable for use with the inventively designed device 1 for winding and shaping hair strands. In Fig. 2B, a hair strand H lying in the winder 4 is also schematically indicated.

The winder 4 has in this case on a base 8 which is detachably connectable to the drive shaft 3, four axially parallel projections 9a, 9b, which in pairs diagonally opposite each other have the same cross sections. The extensions 9a, 9b have in the exemplary embodiment in the axial direction in each case the same lengths. The projections 9a, 9b are arranged at a distance from one another, wherein they define strand guide paths 4a, 4b between each other for passing a strand of hair H, wherein the strand guide paths 4a, 4b widen at their radial end regions by formations of curves on the extensions 9a, 9b. The projections 9a, 9b have along the strand guide paths 4a, 4b rounded hair contact surfaces 9c, 9d. The strand guide paths 4a, 4b are S-shaped.

In mathematics, an envelope, also called an envelope or envelope, denotes a 7 AT 504 075 B1

Curve wrapping a group of curves. An envelope 10 of the four extensions 9, which preferably coincides approximately with the circumference of the base 8, is approximately circular in FIG. 2B, but oval shapes are also possible and expressly provided, since waves can be formed by oval winder 4, while round winder Create 4 curls. The smaller the diameter of the envelope 10, the narrower and smaller the curls, the larger the diameter, the larger curls are formed. Likewise, an oval envelope 10 may be variable in the length of its major and minor semiaxes, making it possible to form larger and smaller or weaker and stronger waves.

In the plan view of Fig. 2B, two mutually diagonally opposite projections 9a are provided with an approximately circular cross-section, while the two remaining projections 9b, which also diagonally opposite, have a gland-like cross-section. The reason for the shaping is clearly shown in Fig. 2B. If the hair strand H is inserted diagonally in the strand guide paths 4a, 4b of the winder 4 as shown, the manual or automatic winding process can begin. By the shape of the extensions 9a, 9b is clearly specified in which direction the winding has to be made in order to curl the hair as gently as possible. A visual control of the winding direction can be done either by the hairdresser or self-use by looking in the mirror. It can also be provided a corresponding sensor unit in the handle part for controlling the winding direction, since winding the hair over an edge of the winder causes a different course of the tensile force than winding over a rounded surface. Accordingly, the winding direction can be corrected by the drive unit automatically switches, manually switched by the user via a switch in the other direction or the user turns the device 1 in the other direction. The correct direction of rotation for the embodiment of the winder 4 shown in FIG. 2B is indicated by the arrows. The hair strand H can thereby be easily guided over smooth outer curves 11a, 11b on the extensions 9a, 9b, without sharp bends occur, which can lead to hair breakage. If the strand of hair H accidentally wound in the wrong direction and pulled over edges 12 of the gore-shaped extensions 9b, these edges 12 are precaution rounded rounded to guarantee a hair-friendly course here as well. The material from which the winder 4 is made, it should be so strong that the extensions 9 do not deform or bend together during the winding process, even with a slightly stronger tensile force to allow a uniform curling.

Furthermore, as can be seen in FIG. 2A, the winder 4 may have a structure 13, for example grooves, ribs or other suitable shapes, on the extensions 9 in order to improve the hold of the hair on the winder 4. This can also be influenced by a suitable choice of material and the surface treatment of the winder 4.

In the case of a winder 17 with an oval envelope 20, the explanations described above also apply. Fig. 4 shows in plan view of such an embodiment of a winder 17 with two extensions, 18, 19, which are arranged parallel and spaced from each other and define an S-shaped strand guide path 17a between each other. The hair contact surfaces 18a, 19a of the extensions 18, 19 are all rounded, so that a strand of hair H is never passed over an edge. As indicated by arrows, there is only a correct insertion direction for the winder 17.

In order to enable a simple and rapid shaping and a temporary stabilization of the waves or curls, it is further provided to heat the winder 4, 17. Heat is always an important part of the molding process, as the thermal effect reinforces and at least temporarily fixes the mechanical action of the molding elements. For the inventively designed device 1 is provided to heat the winder 4, 17 and then to wrap the hair strands H, as this heat transfer to the hair strands H can be done. The heating can be done by prior introduction into a heated environment such as a heater, but also inductive

Claims (23)

Heating, heating in hot water or an indirect heat input into the hair through air outlets in the extensions 9a, 9b, 18, 19, through which warm air is discharged through the wound hair strand H, are possible. The material of the winder 4, 17 should therefore have a high temperature resistance, which should be designed, for example up to about 180 °, so that despite cooling effects and heat transfer into the hair satisfactory results can be achieved. The influence of the heat on the hair strand H can be further enhanced by appropriate hair care products such as mousse, styling wax or hair gel, whereby the hold of the formed curls or waves is intensified. It is also essential for the device designed according to the invention that the hair strands H are preferably taken approximately in the middle of their length by the winder 4, 17, so that it is not necessary to take the hair strands H at the top and wound, the user risks in that individual hairs are crooked or kinked due to their different lengths, tear off or even torn from the root of the hair with pain. If, however, the hair strand H is received approximately in the middle, it can be wound up as far as desired, regardless of the length of the individual hair, without the disturbing side effects mentioned above occurring. Furthermore, it is advantageous that the shaping by the inventively designed device 1 prevents a Spitzenkrause and instead allows a tighter curl in the middle region of the hair strand H, so that the whole curl has a higher bounce. In order to loosen up the curls or waves, wraps 4, 17 of different thickness are furthermore provided, since in this way curls or waves of different strength can be produced. Kleinkalibrige winder 4, 17 are also necessary for users with relatively short hair, since short hair can not be wound on thick winder 4, 17. It is possible, for example, to provide the device 1 designed according to the invention with a plurality of round and oval winders 4, 17 in different diameters in the form of a set or system, thereby opening up many design possibilities for the user. A component of the system may be a special comb 14, which is designed so that it allows a preparation of the hair by dividing and receiving and combing out individual strands of hair, before the strand of hair is then inserted into the winder 4, 17 and wound up. The comb 14 is shown in FIGS. 3A to 3C highly schematized in different views. In the plan view of Fig. 3A, the comb 14 appears in two parts with two intersecting parts, which are each bent twice and intersect at the turning point with the other part. From the side view of one of the parts it can be seen that tines 15 of the comb 14 are of different lengths and follow a concave profiling, so that the tines are longer on the outside than inside. Furthermore, the tines 15, as shown very schematically in FIG. 3C, can be embodied so as to be rotatable individually about their longitudinal axis in a receptacle 16, in order to enable faster picking, combing and smoothing of the hair tress to be inserted into the winder. The comb 14 is preferably plugged or clipped onto the handle part 2 of the device 1, but it is also possible to provide the comb 14 with its own handle, so that the user works with both hands. 1.
