Abstract

In order to enable a side pulling out of the winding body (2) from a dried curl in the case of a hairstyle winder (1) consisting of a winding body (2) to be screwed into the hair and optionally a tensioning band (4) serving to fix the untwisted hair, the winding body ( 2) with an adjustable circumference, and means (3) to reduce the circumference of a screwed-in winding body are arranged in the inside of the winding body or at its longitudinal ends.

Description

The invention relates to a hair styler consisting of a bobbin to be screwed into the hair, in particular with a tensioning band extending at least from one to the other longitudinal end of the bobbin for fixing the untwisted hair.

Usual hair style curlers of this type, which are also referred to as water wave curlers, consist, for example, of a metal cylinder of constant diameter with a brush inserted, or of a flocked plastic cylinder. The hair is arrested by holding pins, so-called postiche. The curlers are screwed into damp hair and, after the hair has dried, are unwound in the opposite direction. Unwinding is time-consuming and can lead to a partial destruction of the curls if you act carelessly.

The invention has for its object to provide a curler that is easy to detach from the hair and when used the risk of disturbing the curls formed is significantly reduced. In particular, the winder should at the same time be designed so that it can be produced in one piece or in two pieces by injection molding. The general solution according to the invention is characterized for the hairstyle winder mentioned at the outset by an adjustable winding body circumference and actuating means for reducing the circumference of a screwed-in winding body.

A winding body wrapped with hair, according to the invention, can be shrunk, preferably after the curl has dried, to such an extent that it can be pulled out of the curl laterally. Because of the reduced diameter of the winding body, there is no risk of the dried curl being impaired.

It is not possible to separate the winding body and hair by pulling them out to the side in the case of conventional metal winders because of the brush located therein, the bristles of which are caught on the hair. Of course, even a flocked, solid plastic cylinder cannot be pulled out of a dried curl without destroying the curl.

To change the circumference, the winding body according to the invention can consist, for example, in its outer skin of a material which is elastically stretchable in the circumferential direction. An elastic skin made of plastic or rubber, which can also contain holes for ventilation, on a frame that can be mechanically expanded or contracted in the radial direction is suitable. The winding body can also consist of an essentially only flexible, in principle cylindrical base body with at least one dividing line extending from one longitudinal end to the other. The means for enlarging or reducing the circumference of the winding body can then consist essentially of pushing the winding body apart from the inside and thus increasing the gap on the respective subdivision line. To reduce the circumference of the winding body, only the force acting from the inside is then to be relaxed, so that the winding body again assumes its original, for example cylindrical, shape.

Furthermore, the winding body can be produced from partial shells or the like which are delimited in the longitudinal direction of the dividing lines. The partial shells can butt against one another at the dividing lines, with tongue and groove or toothed and / or connected with a hinge or the like. It has proven to be advantageous to design the winding body as a one-piece molded part with four quarter shells and three folding hinges arranged in the longitudinal direction. Also advantageous is the construction of the winding body from a multiplicity of stator lamellae which are parallel to one another and to the longitudinal axis of the winder and which are held together with play (in the direction of the winder circumference), so that the winding body circumference can be made adjustable.

According to a further invention, adjustment devices in the interior of the winding body or on one or both open ends of the cylindrical body serve as means for expanding or collapsing the winding body. Preferably, a stamp guided in the winding body and to be actuated from at least one longitudinal end of the winding body and means interacting with the stamp are provided for expanding or contracting the circumference or diameter of the winding body. The arrangement of the actuating means so that they can be handled from the longitudinal ends of the winding body ensures that the individual winding body is to be collapsed without touching the wound curl in an impairing manner. The term "stamp" here includes not only a slide designed as a solid rod or the like, but generally means for actuating the expanding and / or collapsing devices provided in the inside of the winding body, for example a guide with a Bowden cable which is used to adjust the circumference of the winding body serves to fall under the term "stamp".

The stamp preferably has a position within the winding body which is automatic or which is automatically adjusted when the hair is opened, in which the winding body has its maximum diameter. In use, it cannot then happen that a curl is turned on a winding body of minimal diameter and therefore cannot be separated from the winding body after drying without unwinding. The above-mentioned preferred position of the stamp within the winding body is achieved, for example, by an elastic restoring force acting on the stamp or by connecting the tensioning band and stamp such that when the tensioning band is fastened, the stamp is automatically drawn into the position in which the winding body has the maximum diameter owns.

According to a further invention, the hairstyle winder consists of a winding body to be screwed into the hair, which is made up of a plurality of bar lamellae which are parallel to one another and to the longitudinal axis of the winder, and which has means for changing the circumference of the winding body which cooperate with the punch lying in the longitudinal axis of the winder. For a simplified production, it is advantageous if the bar slats are formed with one of their longitudinal ends on one longitudinal end of the stamp via at least one film hinge and if the opposite longitudinal ends of the bar slats have means for latching in a position on the circumference of the punch. Such a winding body can be produced in one or two parts by injection molding and can be erected or assembled in the simplest way.

A hairstyle winder of this type can be produced in one piece if the rod slats are produced when sprayed in a position 180 ° from the working position to a position antiparallel to the longitudinal axis of the winder and pivoted for assembly using the film hinges by 180 ° and at the free longitudinal end of the stamp with one another or with the stamp are snapped together.

The hairstyle winder can also be produced in two parts by injection molding if the one part consists of the stamp and the rod slats formed thereon via at least one film hinge and the other part consists of a snap-on part for the free ends of the rod slats to be plugged onto the free stamp end. The snap-on part to be clipped on can at the same time be designed as an actuation button for longitudinally displacing the stamp in the completely assembled hairstyle winder.

Finally, the material distribution in two-part production by injection molding can also be made in such a way that the rod lamellas are formed by means of film hinges on an essentially circular disc which is to be connected to a coupling end piece of a stamp which is to be produced separately by injection molding. The free longitudinal ends of the rod slats facing away from the disc can then be anchored in a snap-in head at the opposite longitudinal end of the stamp in the working position.

In the last three cases mentioned, the winding body can be produced in one or two parts entirely by injection molding and can be finished in a few simple steps Hair curlers can be mounted. As a means of enlarging and reducing the circumference of the winding body, elements of a jointly spanned inner cone can be molded onto the inner surface of each of the bar lamellae of the erected winding body, such that a plate assigned to the inner cone and radially molded onto the die collapses by moving the die in the longitudinal direction of the winder relative to the bar slats and can be expanded. The relative longitudinal movement of the stamp and the bar slats as well as the expansion and contraction of the radius of the bobbin is made possible by the film hinges provided in pairs in the area of the longitudinal ends of the bar slats.

1 and 2 consists of a basically cylindrical, generally designated 2 winding body, a longitudinally adjustable stamp 3 therein and a tension band 4. The tension band 4 is after unscrewing the hair at the longitudinal ends 5 and 6 of the winding body 2 attached. The winding body 2 can consist of individual rod slats 8 extending in the longitudinal direction 7 of the winder, which are held together loosely and / or elastically in the circumferential direction. For example, the rod slats 8 can be arranged on the inside of an outer skin 9 made of elastic plastic or rubber. The outer skin 9 can have ventilation openings 10.

The stamp 3 guided in the winding body 2 has an actuation button 11 or 12 on at least one longitudinal end. In the exemplary embodiment of the winder 1 according to FIGS. 1 to 3, an approximately symmetrical ball is formed on the stamp 3 with the central axis of the winding body 2 running in the longitudinal direction 7 of the winder 13 arranged. At the same time, the inner surface of the winding body is formed in sections as an inner cone 14 with latching levels 15 and 16 for the ball 13 adjoining its two ends. The design is carried out so that when the ball 13 is arranged on the locking level 16 with a smaller inner diameter, the winding body 2 is spread out but when the ball 13 is arranged on the locking level 15 with the larger inner diameter it shrinks. The two positions of the ball 13 and correspondingly the two winding body settings with minimum diameter and maximum diameter are shown in FIGS. 1 and 2 for comparison.

The provided for fixing the twisted hair on the winder 1 strap 4 can in principle on any a way with the longitudinal ends 5 and 6 of the winding body 2 are connected. It may be expedient to connect the tensioning strap 4 according to FIG. 3, in particular in one piece, to the one longitudinal end 17 of the punch 3. The tensioning band 4 is preferably attached to the longitudinal end 17 of the punch to be pulled when the winding body 2 is spread. It is thereby achieved that when the tensioning band 4 is tightened, the punch 3 (and possibly the ball 13 arranged thereon) is automatically drawn into a position according to FIG. 2, in which the winding body has the position with the maximum diameter.

In the exemplary embodiment according to FIGS. 4 and 5, the stamp 3 is not connected to a ball 13 which interacts with an inner cone 14 of the winding body 2, but rather to a plate lamella 18, which can be folded in by pressing the stamp 3 in the radial direction according to FIG. 4 or according to FIG. 5 is spread. In this case, the stamp 3 can be designed as a guide 19 in which a type of Bowden cable 20 can be moved in the longitudinal direction 7 by pulling or pushing the actuating button 11. The plate lamella can be firmly connected to the guide 19 and / or to the inner surface 21 of the winding body 2 - on the latter at least in sections. 4 and 5, too, the winding body 2 can consist of rod lamellae 8 running in the longitudinal direction 7, preferably with an elastic outer skin 9 stretched over it.

Mechanical means other than those according to FIGS. 1 to 5 can also be provided for expanding or collapsing the winding body. For example, the stretching and relaxing can be done on an inclined plane. Furthermore, the winding body itself can instead of individual longitudinal slats consist of a cylinder with a longitudinal gap, two separate half-shells, three-thirds shells, four quarter-shells, etc. In the case of more than two shell parts, a hinge-like connection between the shells is expediently provided, possibly except for a single dividing line. Some exemplary embodiments are explained with reference to FIGS. 6 to 25.

6 consists of two half-shells 22 and 23 which, when used along a toothing 24, mesh more or less closely. Instead of the teeth 24, a folding hinge 27 and possibly guide cams 28 can also be provided on the dividing lines 25 and 26 of the half-shells 22 and 23 in the case of FIG. 7 on one side and possibly on the other side. Finally, it is possible to form the dividing lines 25 and 26 in the form of tongue and groove according to FIG. 11. If folding hinges are used to connect the partial shells of the winding body 2, two half-shells can be formed according to FIG. in the radial direction, running hinge 29 are connected.

Finally, the hinges connecting the partial shells - each in one or more parts - can also be designed in such a way that individual longitudinal strips of the winding body shell are to be folded radially inward in order to collapse the hairstyle curler, in such a way that the periphery of the winding body in the longitudinal strips in question is, as it were, formed as a groove.

In the exemplary embodiments according to FIGS. 6 to 11, various shapes and designs of cones are provided for adjusting the circumference of the winding body. According to Fig. 6 the stamp 3 has a cone 30 (outer cone) arranged symmetrically with respect to the longitudinal axis 7 of the winding body. This cone 30 is assigned an inner cone 31 rectified on the inner surface 21 of the winding former. The cones - especially the inner cone - can consist of the shape of the winding body 2 and any openings 10 provided therein correspondingly shaped lamellae.

Instead of the inner cone, a two-part circular ring 32 fastened to the inner surface 21 of the respective half-shell 22 or 23 is arranged in the exemplary embodiment according to FIG. 7, the bore 33 of which corresponds to the smaller diameter of the associated cone 30 fastened to the punch 3. If the stamp 3 according to FIG. 8 is inserted into the winding body 2 according to FIG. 7 and this is closed by means of the folding hinge 27, the circumference of the winding body can be widened by pressing one or the other actuating button 11, 12 of the stamp 3 according to FIG. 9 or according to FIG 10 to be shrunk. In the exemplary embodiment according to FIG. 8, a double cone is provided, by means of which it is possible to reduce the circumference of the screwed-in winding body by pressure on one or the other longitudinal end.

In principle, similar to the exemplary embodiment according to FIG. 6, the internal mechanics of the hairstyle winder according to FIG. 11 shown as an explosive pattern are designed. The main difference is that instead of one cone 30, two cones 30a and 30b (outer cones on the stamp) are provided, which correspond to inner cones 31a and 31b on the inner surface of the respective half-shell of the winding body 2. In the exemplary embodiment according to FIG. 11, the tensioning strap 4 is attached to that longitudinal end of the stamp 3 attached, which is to pull out to expand the hairstyle curler in the direction of the inside of the curler. At the other longitudinal end of the plunger 3, the tensioning strap 4 can be locked via an eyelet 34 on a hook 35 or the like of the actuating button 5 located there.

In the exemplary embodiments according to FIGS. 6 and 11, the stamp 3 is surrounded by an elastically attached ring 36, the ring 36 engaging in an annular groove 37 in the inner surface 21 of the respective partial shell of the winding body 2. The annular groove 37 is preferably deeper in the radial direction than the dimension of the maximum change in diameter of the winding body 2 provided. The ring 36, which is made, for example, of rubber or another elastic material and / or is correspondingly elastically suspended, has the task of always changing the punch 3 into a normal or to reset the original position. As a rule, the position in which the hair stylist has its maximum diameter is selected as the original length. This ensures that the winder always has the largest diameter when it is screwed in and can only be moved from the original position into a position with a reduced diameter by moving the punch 3 or other actuating means.

FIGS. 13 to 16 show a hairstyle winder in which the circumference is changed via slots 39 provided in disks 38 attached to the longitudinal ends of the stamp 3. Cams 41 which are firmly connected to the partial shells 40 of the winding body shell engage in the slots 39. Since the slots 39 are clearly inclined, for example inclined by 30 ° to 60 °, against which the circular surface covered by the cams when the punch 3 is rotated about its longitudinal axis 7 is defined by Rela tiv rotation of the winding body jacket and stamp an expansion or contraction of the winding body 2 reached.

17 to 20 and FIGS. 21 to 25 consist of partial shells 42 which extend in the longitudinal direction 7 and which are integrally connected to one another by multi-part film hinges 43. At a separation line that may be caused by production, the parts that abut each other on the peripheral periphery can be fixed, i.e. inseparable, to be connected. In these exemplary embodiments, the collapse of a winding body is brought about by pulling in the partial shells or film hinges in the radial direction.

In the exemplary embodiment according to FIGS. 17 to 20, the stamp 3, which can be rotated about its longitudinal axis 7, has a cross section in the form of a cam star 44 at two points. The individual cams 45 of the star 44 are assigned 2 counter cams 46 on the inner surface 21 of the winding body, such that the cams 45, 46 stand tip to tip in the position with the maximum winder circumference and the counter cams (or outer cams) 46 engage in the armpits 47 between the cams 46 of the star 44 in the position with the minimum winding circumference. In the actuating button 11 according to FIGS. 17 and 18, slots 48 can be provided (for example also for locking purposes), similar to the exemplary embodiment according to FIGS. 13 to 16, which engage in the cams 48 projecting from the winding body 2.

According to FIGS. 21 to 25, in order to expand or collapse the winding body, as in FIGS. 6 to 11, inclined planes 50 and abutments 51 interacting therewith are provided on the inner surface 21 of the winding body. How to 24 and 25 results in particular, when the partial shells 42, possibly supported by the cams 50/51, sink in, a support 52 of the film hinges 43 is simultaneously lowered, ie pressed into the interior of the stamp 3.

The following exemplary embodiments described with reference to FIGS. 26 to 46 are used to explain features of the hairstyle winder which are particularly favorable for one-part or two-part manufacture by injection molding. In principle, all of these winders can be expanded and collapsed in the same way as the previous devices and equipped with a tensioning strap. In particular, the embodiment according to FIGS. 1 to 3 can advantageously be produced according to the principle described below.

For example, the entire hairstyle winder according to FIGS. 26 to 32 can be produced in one piece by the injection molding process if the bar lamellae 8 are molded in a manner pivoted in a direction antiparallel to the longitudinal direction 7 of the winder in a direction 180 ° from the working position.

26, 28 and 31 are to be connected to the punch 3 and, respectively, to a washer 54 formed on the longitudinal end 5 thereof by means of two film hinges 53. In the position according to FIG. 26, in which the entire body is to be sprayed directly, the means assigned to the bar fins 8, in particular cone pieces 56, lie on the outside of the bar fins 8. To simplify the drawing, only a few cone pieces 56 are shown schematically in FIG. 26 shown.

An enlarged drawing of the free end piece of a bar lamella 8 is shown in perspective in FIG. 27. 26 and 27 have latching grooves and springs 57 on the side edges facing the respective neighboring lamella, which enable the free longitudinal ends of the bar lamellae 8 to be ring-shaped around the punch 3 after the pivoting in the direction of arrow 55 into the working position to snap into one another such that the free ends of the bar lamellae 8 encompass the circumference of the longitudinal end 6 of the punch 3 as a fixed ring — movable relative to the punch. For the mobility of the bar slats 8 relative to the punch 3, the bar slat 3 has two additional film hinges 58 adjacent to the free end.

With reference to FIGS. 29 to 32, it is explained how a hairdressing device erected from the blank according to FIG. 26 can be operated in practice. First of all, after the bar slats 8 have been pivoted into the working position and the free longitudinal ends of the bar slats 8 have been coupled into one another on the circumference of the free longitudinal end 6 of the stamp 3, the winding body is expanded in principle in a manner similar to that in FIGS. 1 and 2, in that the radial plate on its circumference 59 stamp 3 is moved in the longitudinal direction 7 of the winder so that the plates 59 reach the upper locking position 15 of the cone pieces 56. 29 and 30, the film hinges 53 and 58 lying closer to the stamp 3 are then stretched and the film hinges 53 and 58 further away from the stamp 3 are bent by approximately 90 °.

This relative position changes when the plunger 3 is pressed in the direction 60 according to FIG. 31 and the plates 59 disengage from the upper locking levels 15 of the cone pieces 56. Because by moving the stamp 3 in the direction 60 the entire winding body 2 is simultaneously stretched parallel to the longitudinal axis 7, the film hinges 53 and 58 adjacent to the stamp 3 are bent and the respective other film hinges 53 and 58 are stretched to a greater or lesser extent. As a result, the radius of the winding body 2 is reduced approximately by the distance between adjacent film hinges 53 and 58; the ratio results approximately from a comparison of FIGS. 30 and 32.

The hairstyle winder can also be produced in two parts by injection molding. Two exemplary embodiments are explained with reference to FIGS. 33 to 39 and 40 to 46.

According to FIG. 33, the body produced directly by spraying consists of approximately radial, star-shaped from the punch 3 or from the circumference of a rod lamella 8 projecting from the periphery of a disc 54 attached to its longitudinal end 5 (similar to FIG. 26). These are similar to those in FIG 26 and 27 are equipped along their length with one, two or more cone pieces 56 to match plates 59 surrounding stamp 3. At the boundary between the pane 54 and the bar slats 8, two film hinges 53 running parallel to one another are again provided.

As in the exemplary embodiment according to FIGS. 26 to 32, two film hinges 58 running parallel to one another are also produced at the free longitudinal end of the rod slats 8. The longitudinal ends of the rod slats 8 themselves are designed as latching cams 61, which are to be latched into latching holes 62 of a latching piece 63 which can be slidably placed on the free end 6 of the punch 3, preferably with an actuating button 64. 35 and 38 therefore need the rod to mount the hairstyle winder lamellae 8 to be pivoted in the arrow direction 55 only by about 90 ° until they are parallel to the longitudinal axis 7 of the winding body 3.

This position and the operation of the assembled bobbin 2 are explained with reference to FIGS. 35 to 39. Thereafter, the winding body 2 can be expanded and collapsed in a similar manner to the exemplary embodiment according to FIGS. 28 to 32 by longitudinally displacing the stamp 3 in the direction 60. The difference between the two exemplary embodiments lies above all in the type of coupling of the free ends of the bar lamellae 8. For a good guidance of the ram 3 in the longitudinal opening 65 of the actuating button 64 assigned to it, it is advisable to use a square profile according to FIG. 36 at this point to provide both for the longitudinal end 66 of the punch 3 and the opening 65 of the actuating button 64. 35 to 39 correspond in turn to FIGS. 29 to 32.

The further two-part hairstyle winder to be produced by injection molding is explained with reference to FIGS. 40 to 46. In this case, according to Fig. 40, the one component to be produced directly by injection molding consists of the rod fins 8, e.g. with cone pieces 56, and a plate 54 holding the plate slats 8 together via film hinges 53 with a plug guide 67 for inserting the separately manufactured stamp 3 according to FIG. 41. The stamp 3 has a fitting part 68 for the plug guide 67 at one longitudinal end and a fitting at the other longitudinal end Coupling part 69 for latching locking cams 70 provided at the longitudinal end of each of the rod plates 8. For assembly, the stamp 3 is inserted with the fitting part 68 first in the direction of arrow 71 into the cylindrical basket spanned by the rod plates 8 according to FIG. 40.

In this exemplary embodiment, too, two film hinges 53 and 58 running parallel to each other are provided on both longitudinal ends of each rod lamella 8. The punch 3 is also equipped with radial plates 59 which interact with the cone pieces 56. The exemplary embodiment according to FIGS. 42 to 46 essentially coincides with the features of the exemplary embodiments according to FIGS. 28 to 32 and 35 to 39, except for the type of connection 69/70 of the rod slats 8 with the stamp 3.
