Description

The content of the invention

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair styling device having a handle portion, a heating unit having a heating region for heating hair, a cooling region, and a styling element for hair styling. The invention further relates to a hair styling method, in particular using the hair styling device of the invention.

  Numerous devices and methods of the type described above are known in the art. For example, EP0 021 224 B1 discloses a gas power curl iron type hair treatment device. This curling iron is composed of an elongated handle portion and a heating portion adjacent to the elongated handle portion. The handle portion further includes pivot hair holding clamp type pressure generating means. For hair styling, especially to curl or wave the hair, the end of a strand of hair, i.e. the tip of the hair, is inserted between the curly hair and the hair holding clamp and held in place Is done. In a later operation, the hair is wound around the hair winding from the top of the hair to the root level at the bottom. In order to set the hair for a certain period of time, the hair holding clamp is lifted away from the curly hair, and the curled or waved hair is pulled down from the curly hair.

  From DE 32 15 232 A1, other methods for styling hair by heating operations and hair styling devices therefor are known. In this specification, a part of the air generated by the fan is distributed to the hot air chamber of the cylindrical winding through the heating coil and discharged through the radial hot air outlet opening. A bypass conduit arranged to extend through the heating coil directs the cooling air into the hair wrap cooling air chamber. The hair to be shaped is placed around the hair wrap and then moved off the scalp but first slid over the outer wall of the hot air chamber and then slid over the outer wall of the cooling chamber. When this happens, the hair is first heated and then immediately cooled in a sequential order. The wave and / or curl shape produced by this method depends on the diameter of the winding.

  Other specifications-German utility model no. DE-GM 77 26 363 has an electrically heatable rod element, a reverse cross-sectional shape meshing with the rod element, a clamp structure movably mounted thereon, and a handle connected to the rod element And a curl bar.

  In a hair styling device known in the art, the diameter or shape of the heated hair curl determines the type and shape of the curl, in particular the size of the curl obtained.

  Therefore, the object of the present invention is to improve the prior art, in particular, curling with a curl diameter, for example, a hair styling for application to a hair styling device that allows the type and shape of the curl to be created independently of the diameter of the curly hair. Apparatus and method are provided. Furthermore, it is desirable that the curls and waves created with the hair in this way be made to last as long as possible.

  According to the invention, this object is achieved by a hair styling device that introduces the features of the prior art part of claim 1, wherein the styling element is formed as a styling edge, the styling edge being provided downstream of the heating area. The cooling area is provided downstream of the styling edge, the hair to be styled can be heated in the heating area, the heated hair can be molded on the styling edge, and the shaped hair can be cooled in the cooling area is there. It is said that the styling element as a styling edge is equipped with a device for heating and cooling areas, and the type and shape of the curl can be changed in a simple way and is independent of the curly and heating geometry. Means are provided to provide benefits.

  Advantageously, the shape of the heating part can be any geometric shape, but it must be ensured that good heat transfer can be effected from the heating part to the hair to be styled. The heating unit can be heated with gas or electricity, and at least a temperature suitable for hair shaping should be considered for heating the hair. As soon as it leaves the heating zone, the heated hair is shaped on the styling edge by being bent and tensioned on the styling edge of the present invention-under tension-pulled above the styling edge. The This styling, especially curled and waved hair, is then led to a cooling area that immediately follows the styling edge, which is either an active cooling area or a passive cooling area, and energy from an external source. It is desirable to be able to operate without being supplied. This device has the attendant advantage that upon leaving the styling edge, the hair is immediately cooled without further heating and the resulting curls and waves last longer.

  The essentially arcuate cross section of the styling edge is particularly advantageous for hair styling. In particular, this arcuate cross section may be in the form of a circular arc of constant radius where the hair to be shaped is pulled over, but considering that the polygonal cross section can be considered almost arcuate, the cross section is polygonal or It is also possible to use similar styling edges.

  In a particularly advantageous shape of the styling edge, those with a radius greater than 0.1 mm, in particular between 0.5 mm and 5 mm, are recommended. Of course, it is understood that this shape requires not only that the arc shape is associated with the corresponding radius as such, but also includes polygons with dimensions larger than 0.1 mm and similar shapes that can be comparable to the radius. It will be. For example, 0.5 mm diameter styling aids (aids) produce small diameter curls, for example 3 mm diameter creates large diameter curls. Styling edges with diameters greater than 5mm do not create curls, but rather create waves in the hair. Providing a styling edge with a diameter greater than 0.1 mm advantageously achieves a hair shaping function that can be restored without causing damage to the hair, but damage to the hair, for example when a sharp styling edge is used Will occur.

  In a further feature of the present invention, the styling edge is arranged substantially parallel to the main axis of the hairdressing instrument. This feature is based on a substantially straight styling edge. Advantageously, this feature provides an efficient and structurally simple styling edge placement. Further, the pressurization generating means and the heating section extend substantially equally in the longitudinal direction. However, it will be appreciated that other shapes of the pressure generating means and heating section are possible.

  Styling edge tangents are arranged to intersect at an angle of less than 180 degrees. One purpose is to create a small bend in the hair because it is pulled over and pulled by an obtuse angle, eg, 150 degree styling edge. In shapes where the styling edge has an acute angle, for example 30 degrees, the hair to be shaped is conveniently bent to a significant degree as it is pulled around the surface of the styling edge. The tangent of the styling edge may enclose an angle of 0 degrees, i.e., for example, if the styling edge is placed at the end of a narrow piece of sheet metal and the cross section is a semicircle, they are placed parallel to each other May be.

  With the pressure generating means, a contact pressure is applied to the hair to be shaped, which can be inserted between the heating part and the pressure generating means. For some purposes, good heat transfer from the heating section to the air is achieved, and for other purposes, clamping pressure is applied to the hair to be styled. Since it acts as a holding force, this clamping force opposes the pulling force that moves the hairstyling tool against the hair by the user.

  The styling edge itself may be provided on a pressure generating means configured as a styling clamp known per se. For this reason, a simple styling edge device has been proposed that advantageously requires no other means in the hairdressing instrument than those already provided. The styling clamp is specially configured as a styling clamp that is movable relative to the handle and / or the heating part and is movably joined to the handle part by means of a rotary joint known per se.

  In a further inventive feature, the styling edge is provided on the heating part, which may be configured as a heating part integral with the styling edge, for example. Thus, this advantageously reduces the number of components required to the minimum where only a single component for hair heating and styling is required.

  In a special shape, the heating part has an elliptical, tear-shaped or similar cross-sectional area. By changing the styling edge at the tapered end of the tear-shaped cross-sectional area, various winding angles of the hair can be achieved in the heating section, advantageously resulting in various shapes and sizes of curls.

  In a further feature of the invention, it is proposed to provide a styling edge on another styling means. This is convenient, for example, when a specially shaped curl is desired.

  In this aspect, the further styling means may be conveniently connected to the pressure generating means, in particular the holding clamp and / or the cooling member. As a result, these two components may be configured as a subassembly suitable for attachment of a handle portion or a heating portion.

  Conveniently, the styling means is connected at one end to the handle or heating part by a rotary joint, in particular a spring-loaded rotary joint similar to the hair holding clamp known in the prior art, so Hair can be easily inserted between the heating part and the rotatable styling means.

  In a special embodiment of the invention, a cooling member is provided for cooling the shaped hair, which cooling member is in particular arranged in the styling edge region. Conveniently, this makes it possible to obtain a particularly durable curl shape in that the hair after styling is cooled on the cooling member to “fix” the curl.

  By arranging the heating part, the styling edge and / or the cooling element essentially parallel to each other, these components can be conveniently arranged in a close spatial relationship with each other. Therefore, the length that the hair to be styled moves from the heating unit to the cooling member due to the styling edge is shortened, and the curl setting is improved.

  By placing the heating and cooling members in a relatively spaced relationship with each other, the warm and cold regions of the hairdressing device are supplied separately and the two temperature zones do not interact significantly.

  In another feature of the invention, the styling means and the cooling member are rigidly connected to each other and are movably disposed with respect to the heating unit. This advantageously allows the styling means with the styling edge to form a subassembly with a cooling member and allows the hair to be easily inserted into the gap between the heating part and the styling means.

  In a particular shape, the cooling member is made of a material that conducts heat well, such as aluminum or the like, or a hollow aluminum body filled with paraffin. Advantageously, a good cooling element cooling effect has been proposed for effective cooling of previously heated styling hair, ie hair with "curled" curls.

  In order to enhance the cooling effect, it is proposed to provide a cooling element with a thermally conductive coating and / or cooling ribs. This advantageously ensures good heat dissipation by the cooling member.

  In certain embodiments, the cooling member is configured as a cooling member that can be actively cooled. This is achieved, for example, by cooling air, which can occur in the handle part of the hairdressing instrument. The cooling action may be created by a Peltier element or an equivalent device. This advantageously results in intense cooling of the previously heated hair, producing a more durable curl.

  In another aspect of the hair styling apparatus, the heating unit and / or the styling means may be provided with space means and / or guide means on the outside. These means are configured in particular as ribs and advantageously allow a hair guide adapted to wrap a part of the instrument around the front part for some purposes, but for other purposes it is a space. It acts as a means to prevent the user from touching the warm part of the heating part.

The ribs are arranged essentially transverse to the main axis of the instrument and a passage is formed between each of the two adjacent ribs and extends around the periphery of the heating part and / or styling means and is molded within the passage. The hair is conveniently and easily acceptable.
At least the ribs of the hair styling device are provided as boundary ribs, and the hair guided around the heating part and / or styling means is advantageously provided for slipping off the heating part and / or styling means by this special rib. Reinforced.

  In a special shape of the hairdressing device, the two outermost ribs project at least in the area beyond the remaining ribs on the styling means and / or heating means in the plane transverse to the main axis of the device and are configured as boundary ribs. ing.

  The ribs are preferably provided in an arc, wave or arrow shape on at least one component, in particular the heating part. This rib shape is advantageous in that the hair adapted to be guided around this special component experiences more friction than the friction on other components, in particular the styling means. This effect is intended to prevent the user from drawing hair outside the heating section.

  In a particular feature, these ribs are arranged on the heating part substantially parallel to the main axis of the instrument. Conveniently, especially due to the increased frictional resistance, this makes the user face both visual and mechanical obstacles, thus preventing the user from pulling the hair beyond the outside of the heating part. Is intended.

  Particularly advantageously, the ribs, in particular the ribs on the heating part which are arranged substantially parallel to the main axis of the instrument, are also arranged substantially radially with respect to the main axis of the instrument. As such, these ribs extend essentially vertically away from the outer surface of the appliance, particularly the heating section.

  At least one of the outermost two ribs is configured as a boundary rib, this particular rib or the two outermost ribs protruding at least in the region beyond the inner rib lying essentially radially. . This has the advantage of giving a visual distinction between the innermost rib placed between the two outermost boundary ribs.

  Particularly advantageously, the at least one boundary rib is configured as a wing with a rear end portion of the boundary rib on the side close to the handle portion higher than the front end portion of the boundary rib on the side remote from the handle portion. Thereby, it becomes possible to apply a boundary rib immediately with respect to the area | region where the cross section of a hairdressing instrument differs, and it avoids that the edge and corner | angular part of a boundary rib protrude.

  In a special further feature of the invention, the heating part has at least one elongated rib immediately adjacent to the heating zone, which is arranged substantially parallel to the main axis of the instrument and corresponds to the pressure generating means. It protrudes at least in a region beyond the surface of the heating part in the radial direction. Thereby, in design and visual appearance, it has been proposed to interrupt the heating zone, the corresponding surfaces of the heating zone and the pressure generating means have an essentially conforming shape, It can be biased into direct contact with the heating area. Due to the blockage of the heating zone surface by at least one elongated rib, the hair inserted between the heating part and the pressure generating means is advantageously bent and the hair is guided away from the heating part.

  Particularly advantageously, the heating part corresponding to the pressurizing means is such that the central section continues in an essentially convex direction, adjoined by at least one outer section formed by elongated ribs that continue in an essentially concave direction. The surface has a surface configured substantially perpendicular to the main axis of the instrument. For this reason, it has been proposed to efficiently bend and guide the hair away from the heating zone.

  In a further feature of the invention, the clamp is rotatably mounted on the styling means, in particular the cooling member. This gives the possibility of further movement of the clamp, and advantageously allows adjustment movement between the clamp and the heating part.

  In this arrangement, the pivot axis of the clamp is arranged substantially parallel to the major axis of the heating part and / or the cooling member, and thus substantially parallel to the main axis of the instrument. Conveniently, this allows the clamp to be pivotally mounted within the cooling member with pivot pins. This has the favorable result of a uniform contact pressure of the hair over the entire contact surface of the heating part.

  Still further, the clamp is preferably constructed essentially mirror-symmetrically, as seen in one plane across the major axis, and the pivot axis is symmetrically on that plane. Conveniently, this allows the clamp to perform a uniform rotational movement on either side of the symmetry plane.

  In a particular shape of the invention, it has been proposed to provide an instrument, in particular a handle part, having an ellipse, an ellipse or a similar external contour in a plane perpendicular to the main axis. Such a closed shell shape has the advantage that the handle is well placed on the user's hand and the user feels uncomfortable when the hairdressing instrument rotates about its long axis. The shape of the handle is intended to further support the new manipulation of the instrument, which pulls from the user's scalp using linear motion rather than rotating around the long axis. In that respect, it differs significantly from known hair styling instruments.

  In a further feature, it has been proposed to provide the styling means and the heating part with a substantially constant area of a cross-section that is substantially along the main axis of the instrument and smaller than the cross-sectional area of the front end area of the handle part. Conveniently, this results in a clear separation between the hair treatment part having a heating part and styling means at one end and the handle part at the other end. Furthermore, the large surface area of the handle provides the user with a good, firm and secure grip.

  The cross-sectional area of the handle portion is continuously reduced from the front portion to the free end of the rear handle portion, which also allows the user to handle the instrument more vigorously and with less gripping force.

  In a further particular feature of the invention, the two styling elements, each having at least one, especially two styling edges, include a styling element that forms a clamping area for receiving and guiding the hair to be styled The opposite surface is provided. In this device, a heating zone is provided in the clamping area on at least one of the two styling elements. Due to the substantially symmetrical shape, this is advantageous and provides a hairdressing instrument that makes the manipulation of the instrument particularly easy. The hair to be styled can be inserted from any side into the clamping area between the two styling elements and can be pulled around any styling edge. Thus, the correct operation of the appliance by the user is automatically ensured, i.e. the hair to be styled is first heated, then the heated hair is styled at the styling edge and then cooled in the cooling zone.

  In a particular feature, at least the first of the two styling elements is configured as a pressure generating means and is movably mounted relative to the handle portion, in particular the second styling element. This has the advantage that only one movable styling element is required to bias the hair to be styled against the corresponding styling element.

  Conveniently, at least the first of the two styling elements has a heating zone and is thus configured as a heating part that can be heated directly. Therefore, since only one heating element is required, a low-cost version of a hairdressing instrument is proposed. For example, by providing heating elements in the two styling elements that directly heat the first and second styling elements and the second styling element, heat can be quickly introduced into the hair to be styled.

  In certain additional features, the second styling element is formed of a thermally conductive material, which is urged into contact with the first directly heatable styling element and then indirectly in contact with the first styling element. Can be heated. This advantageously eliminates the need for direct and positive heating in the second styling element. Both styling elements warm up in a relatively short time, and the hair inserted in the clamping area is heated uniformly from both sides.

  Outside of the heating zone, the styling element has a cooling zone, and a single styling element merges the styling edge into the heating zone, similar to the cooling zone. For this reason, particularly space saving solutions for hairdressing instruments have been proposed.

  The cooling zone consists of a cooling element that can be actively or passively cooled, which guarantees the temperature difference required between the heating zone and the cooling zone for curl or wave setting.

  Between the heating part of the styling element and the cooling member, for example, a thermal decoupling arrangement configured as a heat insulating material is provided. As a result, a necessary temperature gradient is realized in the minimum installation space.

  Advantageously, the clamping area between the two styling elements is configured as a planar slot extending in a direction essentially parallel to the main axis of the instrument. With this substantially symmetrical shape of the clamping area, on the one hand, regardless of the direction of pulling the instrument through the hair, on the other hand, between the hair and the styling element, regardless of the direction of rotation of the instrument around the axis Ensure constant frictional resistance.

  In a plane extending substantially perpendicular to the instrument's main axis, the styling edges are each arranged at the slot end and / or at both styling elements.

  Therefore, the geometry of the hairdressing device has the desired effect of creating a permanent curl or wave in the shaped hair, regardless of the direction in which the device moves in the hair and the direction of rotation of the device. produce.

  In a specific embodiment of the invention, which may be an independent invention, a hair styling method is proposed, in particular using the hair styling device of the invention, in which the hair is heated in the heating zone, cooled in the cooling zone and shaped with the styling elements. ing. According to the invention, the hair to be styled is first heated in a heating zone, the heated hair is then molded with a styling element configured as a styling edge, and the hair so shaped is later cooled in the cooling zone Chilled in.

  In order to shape the curl, there must be a relative movement between the heated hair and the inventive styling edge. In known hair styling methods, it is customarily that the free end of the hair is clamped between the pressure generating means and the heating means, moving from the end of the hair to the root level, customarily Will continue to wind the hair around the hair. In contrast, the method of the present invention is proposed to move from the root level to the free end of the hair, and the heated hair is pulled over by the styling edge during movement. An essential aspect of the present invention is that the heated hair is formed on the styling edge of the invention as soon as it leaves the heating zone, which is caused by the hair being bent over the styling edge. Achieved by tensioning under tension. So shaped, especially curled and waved hair, is then cooled in a cooling zone that immediately follows the styling edge, which is positive or passive, ie without supplying energy from an external source. It is possible to operate. Because this is present, the hair cools as soon as it leaves the styling edge, creating a more lasting curl and wave that is not exposed to further heating.

  Advantageously, the hair is heated at least to the forming temperature in the heating zone, which is also referred to as the glass temperature Tg corresponding to about 30% relative humidity in the hair, approximately 120 ° C.

  In order to produce the necessary tension in the hair, the hair is inserted between the pressure generating means and the heating part, so that the clamping force acts on the shaped hair and when the heated hair is pulled around the styling edge the hair The elongated side of the is stretched. This conveniently forms a durable curl on the hair. In this method, the greater the amount of hair stretched, the greater the curl effect. Still further, the type and size of the curls and waves that are created does not depend on the size, especially the diameter of the hair curl, but rather is only one side of the hair stretched on the styling edge, The method proposed here is advantageous. In that way, the elongated side of the hair that is close to the styling edge, i.e. the specific side of the hair that is pulled directly by the styling edge, is subject to compressive forces and therefore occurs on the elongated side opposite the hair It supports the tension.

  In a particularly advantageous embodiment of the invention, the elongated side of the hair facing away from the styling edge is stretched by at least 1%. This is an efficient means of curling the hair regardless of the diameter of the curly hair. The changes experienced when the hair is stretched to an amount below about 30% are advantageously fully recoverable, thus avoiding the risk of damage to the hair when stretched over the styling edge.

  The elongated side of the hair close to the heating section is pulled over and stretched by the styling edge, and the curl desired by the user is noticeably produced.

  Alternatively, the elongated side of the hair facing away from the heating part can be bent and stretched on the styling edge. Thus, advantageously, this also allows for curling of the hair.

  For good curl formation, the hair is pulled and pulled by the styling edge while being taut. This is achieved by the hair being clamped between the pressure generating means and the heating part, so that a holding force is applied to the hair. Thereby, the tension | pulling and the holding force which the user generate | occur | produced when moving a hairdressing instrument with respect to hair neutralize. This taut hair condition advantageously contributes to curl formation (isconductivc).

  The hair movement direction downstream of the styling edge, i.e., the styling edge movement direction upstream, i.e., the hair movement direction when leaving the styling edge is the same or opposite to the movement direction before reaching the styling edge. It is. The same direction of movement upstream or downstream of the styling edge allows for a more uniform and advantageously lower tension of the hair, and bending in the direction in which the hair is moved over the styling edge requires a greater tension and is advantageous Produces a stiff curl.

  In a particular embodiment of the invention, it has been proposed to cool the hair after it has been stretched by moving, in particular pulling, the curled hair along the cooling element. Thereby, the curl is well set by “freezing”.

  A particularly good styling result is obtained when the elongated side of the stretched hair faces away from the cooling member and is pulled around the cooling member at this location.

  Depending on the relative speed of the styling edge to the hair being styled, the shape of the curl changes. Thus, a stiff curl is conveniently created by guiding the styling edge against the hair with a slow motion, but a rapid guiding motion is applied to create a generous curl.

  The surface temperature of the cooling member is 85 ° C. or less, whereby a durable curl is obtained. Since the formation temperature of human hair is about 120 ° C. with a relative humidity of about 30% in the hair, the surface temperature of the cooling member below 85 ° C. ensures that the previously created curls retain their shape well enough It provides a temperature gap sufficient to ensure that.

  The method of the present invention advantageously allows straight hair to be efficiently curled from approximately the root level of the hair to the tip without utilizing the windings required for conventional methods. Furthermore, the hair forming operation obtained by this method is restorable.

  In a particularly advantageous application of the method, the hair is introduced into the clamping area between the two styling members, in any direction until the device is later centered on the main axis and at least part of the hair engages the cooling member But rotating, the hair styling tool is finally separated from the user's head, the heated hair is shaped on the styling edge, so that the styling hair is cooled on the cooling member, Has been proposed. When an instrument with two styling elements is used, the curling and wave styling results are independent of the direction in which the instrument rotates about its main axis.

  The user may insert the hair from any side into the clamping area for styling, rotate the hairstyling tool around its main axis in any direction, and the heated hair will be on the styling edge. And later cooled on the cooling element.

  Further features, advantages, and applicability of the present invention will become apparent from the following description of the embodiment shown in more detail in the accompanying drawings. Any single feature or combination of single features described and / or illustrated in the drawings forms the subject of the present invention regardless of their outline in the claims or their background. Will be understood.

  The hair styling device (FIG. 1) of the present invention is composed of, for example, a cylindrical heating part 6 and a pressure generating means, in particular, a hair holding clamp 8 biased to the heating part 6 by a spring means (not shown). Starting from the root level 14, the hair 2 to be styled is inserted between the heating part 6 and the clamp 8, and the heating part 6 heats the hair to the forming temperature along the contact surface 12 between the two components. At its one end, the clamp 8 has an elongated styling edge 10 on which the bristles 2 are pulled. When the user moves the hair styling device in the pulling direction 16, the heated hair 2 is pulled out through the space between the heating unit 6 and the clamp 8, and when the user leaves the contact surface 12, the hair 2 becomes the styling of the clamp 8. From the root level 14 to the tip, this shapes the hair 2 into a curl that is deflected on the edge 10.

  Another embodiment (FIG. 2) of the hair styling device of the present invention includes an elongate heating section 20 having a substantially tear-shaped cross section. On its elongated side, the heating part 20 has a styling edge 24. The hair 2 to be shaped is heated from the root level 14 through the contact surface 22 of the heating part 20 and bent on the hairstyling tool 24 by the user moving the heating part 20 in the moving direction 26. To achieve this, the user needs to tension the hair 2 in the pulling direction 28 in order to provide a contact force to the tuft 2 on the contact surface 22 necessary for heating.

  Curls that retain their shape particularly well are created by cooling the curls on a cooling member after molding and "fixing" the curls. For this reason, the hairdressing implement comprised by the display of FIG. 1 provided with the clamp 8 which has the styling edge 10, and the heating part 6 is utilized. In this shape, as shown in FIG. 3, the cooling member 30 may be disposed above the clamp 8 and attached to the clamp 8 by a connection not shown. Clamp 8 and cooling member 30 are combined to form styling means 31. The cooling member 30 has a semicircular cross section, and a cooling rib 32 may be attached to the upper arcuate region in order to enhance the cooling action. In this apparatus, the cooling member 30 extends equally in the longitudinal direction parallel to the heating unit 6 and the clamp 8. The movement of the hair styling device in the direction of movement 34 involves first heating the hair 2 on the contact surface 12, then bending on the styling edge 10 and later cooling on the cooling member 30.

  The hair (FIG. 4) is urged by the clamp 8 against the heating part 6 in the region of the contact surface 12 and is pulled around the styling edge 10 when the heating part 6 is moved in the movement direction 16. In the process, the hair 2 is looped over the next end region of the clamp 8 with the styling edge 10. It is in particular the radius 36 of the styling edge 10 that is decisive for the styling outcome of the hair 2 that is shaped to form the curl. The hair must have a minimum radius of approximately 0.1 mm in order to avoid devastation, especially breaking, during shaping. The hair 2 may be wrapped around the styling edge 10 at a substantially right angle as shown in FIG. 4, but the wrapping angle of the hair 2 relative to the styling edge 10 may be larger or smaller than 90 degrees. Depending on the styling results achieved, ie whether small or large diameter curls are made.

  When the hair 2 is pulled around the styling edge 10, the elongated hair side 38 close to the heating part 6 is exposed to tensile stress, while the elongated hair side 40 facing away from the heating part 6 is compressed stress. Exposed to. This difference in hair length creates curls.

  The hairdressing instrument 50 (FIGS. 5, 6, and 7) of the present invention substantially includes a handle portion 54, a heating portion 52, and styling means 72. The handle portion 54 is in turn assembled from a central grip shell 64, a front cover 62, and an end cap 66 arranged in contrast around the main shaft 70. The control unit 68 is provided on the upper side and the lower side of the handle unit. Between the front cover 62 and the front end portion 56, the heating portion 52 is provided with a rib 58, and each two adjacent ribs form a circumferential groove 59 therebetween.

  The ribs 76 of the styling means 72 are disposed substantially perpendicular to the main shaft 70, but the ribs 58 of the heating unit 52 have a sagittal shape that points in the direction of the distal end portion 56. The elongated undulations 60 are arranged on the heating part 52 close to the dividing line between the heating part 52 and the styling means 72.

  The foremost and rearmost ribs of the styling means 72 are configured as boundary ribs 78 protruding beyond the styling means 72 at least in the region in the direction of the heating part 52.

The cut surfaces 108, 109, and 110 in FIG. 6 will be described below with reference to the following drawings.
A cut surface 108 (FIG. 8) taken in the vicinity of the end cap 66 shows an oval shape of the handle portion 54. In this position, the grip shell 64 has a smaller cross-sectional area near the front cover 62. For simplicity, the parts built into the grip shell 64 are not shown. The upper side and the upper side and the lower side of the handle part 54 are provided with a control unit 68 for starting up and shutting down the instrument as in the operation of the styling means.

  In the cut surface taken along line 109 in FIG. 6, the grip shell 64 (FIG. 9) exhibits a larger cross-sectional area than the cut surface 108, and this region is progressive from the rear end of the handle portion to the front cover of the handle portion. Is increasing.

  A cut surface (FIG. 10) taken along line 110 in FIG. 6 shows the lower heating unit 52 and the upper styling means 72. The heating part 52 is surrounded by a rib 58 that essentially extends in the circumferential direction and is connected to the inner region of the heating part 52 by a pin 80 in the radial direction. The styling means 72 includes a cooling member 82 and a boundary rib 78 that surrounds the cooling member 82 at least in that region. Disposed between the heating unit 52 and the cooling member 82 is a pressure generating means in the form of a clamp 84.

  The clamp 84 has a front end portion and a rear end portion, and is rotatably attached to the cooling member 82 with a pivot pin. In this apparatus, the pivot shaft 86 exists in the plane of symmetry between the heating unit 52 and the styling means 72. Styling edge 88 can be recognized at the two lateral ends of arcuate clamp 84.

  The hairdressing instrument 50 (FIG. 11) is essentially composed of a rear handle part 54 and a front part 90 adapted to be subdivided into a heating part 52 and styling means 72. At the rear end portion, the heating portion 52 is rigidly connected to the handle portion 54, but the handle portion 54 is rotatably attached to the rear end portion of the styling means 72. In operation of the control unit 68 on the upper side of the appliance 50, the dividing line 74 between the heating unit 52 and the styling means 72 is sufficient to provide a wedge-shaped opening in which the hair to be shaped is comfortably received. Only open. In order to shape the hair, the styling means 72 is rotated back to the heating unit 52 by the control unit 68 and urges the hair captured in the meantime to the upper side of the heating unit 52. The boundary ribs 78 of the styling means 72 are tooth-shaped and extend beyond the styling edge 88, so that the hair to be shaped is held in the region of the styling means 72 provided with ribs on the outside. In the use of the hair styling instrument 50, the hair to be shaped is therefore drawn through the space between the heating part 52 and the styling means 72, and then bent at the styling edge 88, leading to the outside of the styling means 72. Returned.

  In an alternative to the shape of the ribs 58 shown in FIGS. 5-10, the heating section 52 (FIG. 12) includes elongated ribs 92 on the outside thereof. These are located between the tip 56 of the device and the front cover 62 and are intended to prevent the user from wrapping the hair around the front 90 of the hairdressing device.

  Similar to the display content of FIG. 12, the heating unit 53 (FIG. 13) has elongated ribs 92 on the lower outer side. The uppermost portion of the elongated rib 92 is configured as an airfoil boundary rib 98 that changes its height. At its front end 100 near the instrument tip 56, the rib 98 is significantly lower in height than the rear end 102 near the instrument front cover 62. The hair styling means 72 substantially corresponds to the display contents of FIGS. Due to the height difference, the boundary rib 98 is integrated into the space between the tip 56 and the front cover 62, and neither the corners nor the edges of the rib 98 protrude beyond the external contour of the instrument.

  The heating section 53 and the styling means 72 (FIG. 14) are shown in an open state in which hair can be inserted into the space between these two components for styling. This shaped styling means 72 is essentially composed of the same components as the styling means shown in FIG. 10, and thus includes a clamp 84 with a styling edge 88 and a cooling member 82. In contrast, the heating portion 53 has a series of elongated ribs 92 at its lower portion, which extend essentially radially away from the heating portion 53 and outward. The two outer elongated ribs are configured as boundary ribs and protrude radially outward beyond the remaining ribs 92. An elongated rib on either side of the upper side of the heating part 53 forming the heating zone, extending substantially parallel to the main axis of the instrument and projecting radially at least in the region beyond the upper surface of the heating zone 104 is shown. The upper part of the heating part 53 is subdivided into essentially three different cross sections, which comprise a first central cross section extending in a substantially convex manner. Two outer, essentially concave sections 105, 107 extend adjacent to both sides of the central section. When the hair is placed in the space between the heating unit 53 and the styling means 72 for shaping, and the styling means 72 is urged to the upper side of the heating part 53 by the bottom surface of the clamp 84, the hair to be shaped is formed. Is guided around the styling edge 88 through the two elongated ribs 104 and is therefore directed away from the heating part 53. As a result, the hair to be shaped is inevitably supplied above the cooling member 82 and around the styling edge 88.

  Another embodiment of the styling means 140 (FIG. 15) comprises essentially symmetrically shaped styling elements 112, 114 separated from each other by essentially planar slots 132. In this embodiment, the two styling elements 112, 114 may be arranged in contrast around the main axis 136 of the hairdressing instrument. Each of the styling elements 112 and 114 includes heating portions 116 and 118 and cooling members 120 and 122 that are adjacent to each other on the radially outer side. At least one of the two heating units 116 and 118 needs to be directly heated by the heating element. The second styling element on the opposite side may be heated indirectly by contact heat from the first heating unit or directly by a separate heating element.

  Styling edges 124, 128 and 126, 130 are provided on each heating section 116, 118 at the two opposite ends of slot 132, respectively. Thus, the hair is inserted into the slot 132 from one end for styling and heated. After heating, the styling means 140 is rotated about its main axis 136 by approximately 90 to 180 degrees, and the hair engages the outside of one of the two cooling members 120 or 122. This allows the instrument to be operated easily and safely, regardless of its direction of rotation or movement. In order to thermally decouple the heating part 118 from the cooling member 122 of the styling element 114, it has been proposed to provide an insulation 134 between the two components.

  A styling means of the type shown in FIG. 15, which is essentially symmetrical, is shown in the perspective view of FIG. The handle portion 138, shown with a fragment, has styling means 140 composed in the vicinity thereof of two substantially similar styling elements 112,114. In this shape, the upper styling element 112 is configured as a pressure generating means, and is connected to the control unit 144 on the upper side of the handle portion 138, so that the styling element 112 is rotatable with respect to the styling element 114. It is attached to the handle portion 138. Both styling elements 112, 114 each comprise a heating section with a respective styling edge 128, 130, which extends essentially parallel to the main axis of the hairdressing instrument. Adjacent to the two heating parts of the styling elements 112 and 114 in the opposite relationship are the two cooling members 120 and 122. These cooling members have continuous lateral ribs 142 on their opposite outer sides to guide the hair to be shaped.
