Description

The invention relates to a hair styler consisting of a cylindrical bobbin to be screwed into the hair with a variable body circumference and actuating means for changing the body circumference, and a tensioning band extending at least from one to the other longitudinal end of the bobbin.

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.

Furthermore, hair stylers with variable body size are also known. From FR-A-1000538 a hairstyle curler of the type mentioned is known. This hair-styling curler consists of two half-shells which have cam-shaped levers on each of their ends and can be pivoted about the respective axis as actuation means for changing the circumference of the curler body. There are also set elements on the inside of the half-shells formed, which prevent displacement of the half-shells in the longitudinal direction when changing the winder body circumference. In the case of a hair curler of this type wrapped in a lock of hair, the change in body circumference by actuating the cam-shaped lever elements is only possible with the aid of both hands. Otherwise there is a risk of pulling or tearing on the wrapped lock of hair. Furthermore, due to its four lever elements and their attachment to the half-shells of the winder body, this known hairstyle winder requires a relatively large amount of effort in the production and assembly.

Another elaborate hair styler with an adjustable body size is known from FR-A-1011323. This hair curler consists of four half-shells, two of which each form a rotationally symmetrical body which has a smaller diameter in the middle than at its two edges, and one body formed from two half-shells is arranged in the other. On the front sides, this winding body has pin-shaped actuating means with cross-sectional enlargements, which engage in corresponding openings in the inner or outer half-shells and cause an adjustment of the body circumference. A similar winder body consisting of a half-shell and a further part, which complements this to form a rotationally symmetrical body, with actuating means designed as a continuous longitudinal axis for changing the body circumference is known from FR-A-1003318.

Finally, in US-A-2415586 a hairstyle winder with a one-piece winder body is known, in the interior of which Adjustment of the winder body circumference is arranged in a longitudinally displaceable punch having a cross-sectional expansion.

The invention has for its object to provide a winder that is easy to detach from the hair and when it is used, the risk of a disturbing impairment of the curl formed is substantially reduced, the winder body and the actuating means being designed so that they are in one piece or to be produced in two parts by injection molding.

In a hairstyle curler of the type mentioned in the introduction, this object is achieved according to the invention in that the winding body consists of a plurality of parallel bars in the winding position with respect to one another and to the longitudinal axis of the winder, and the actuating means consist of a rod-shaped stamp arranged in the longitudinal axis of the winder with at least one cross-sectional expansion and thus Profiling to be brought into the engaging detent position and formed on the slats.

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, a flocked, firmer one Do not pull plastic cylinders out of the side of a dried curl without destroying the curl.

The hair styler 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 each other in the winding position and to the longitudinal axis of the winder, and which has means for changing the circumference of the winding body which is located 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 snapping in at a position on the circumference of the punch. Such a winding body can be produced in one piece or in two parts by the injection molding process and can be erected or assembled in the simplest way.

A hairstylist of this type can be produced in one piece if the rod slats are made 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 each other or with the stamp are snapped together.

The hairstyle winder can also be produced in two parts by injection molding if 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 can also be used as Actuation button for longitudinally displacing the stamp in the fully assembled hairstyle winder.

Furthermore, the material distribution in two-part production by injection molding can also be made in such a way that the bar 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 three cases mentioned, the winding body can be produced in one or two parts entirely by injection molding and can be assembled into the finished hairstylist in just a few steps. As a means of enlarging and reducing the circumference of the winding body, elements of a jointly clamped inner cone have been molded onto the inner surface of each of the bar lamellae of the erected winding body, such that a plate which is assigned to the inner cone and is formed radially on the punch by moving the punch in the longitudinal direction of the winder relative to the bar slats and collapsing 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.

To change the circumference, the winding body can consist, for example, in its outer skin of a material which is elastically stretchable in the circumferential direction. An elastic skin is suitable Plastic or rubber, which can also contain holes for ventilation, on a frame which can be mechanically expanded or contracted in the radial direction.

Adjustment devices in the interior of the winding body serve as means for expanding or collapsing the winding body. There is a stamp guided in the winding body and to be actuated from at least one longitudinal end of the winding body, and means for interacting with the stamp 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 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 strap and stamp in such a way that when the tensioning strap is fastened, the stamp automatically moves into the Position is pulled in the winding body has the maximum diameter.

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 strap 4 provided for fixing the twisted hair on the winder 1 can in principle be any one Be connected with the longitudinal ends 5 and 6 of the winding body 2. 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.

To expand or collapse the winding body, other mechanical means than those according to FIGS. 1 to 3 can also be provided. 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. 6-12 and 17-25.

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 also guide cams 28 can 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 have 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 hinged hinge 27, the circumference of the winding body can be widened or depressed by pressing one or the other actuating button 11, 12 of the stamp 3 according to FIG. 9 Fig. 10 are shrunk. In the exemplary embodiment according to FIG. 8, a double cone is provided, which makes it 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 inner mechanics of the hairstyle winder shown in FIG. 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 plunger 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 intended maximum change in diameter of the winding body 2. The ring 36, for example made of rubber or another elastic material and / or 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.

17 to 20 and FIGS. 21 to 25 consists 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 inseparable, to be connected. The collapse of a winding body is effected in these exemplary embodiments 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. 17 and 18, slots 48 can be provided (for example also for locking purposes) into which cams 48 projecting from the winding body 2 can be provided.

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 in particular 24 and 25 shows, 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 Hair roller 26 can be made to 32 in one piece by injection molding of FIG. When the rod laminae 8 are formed when spraying in an ^o rotated 180 from the working position in a direction antiparallel to the Wicklerlängsrichtung. 7
26, 28 and 31 are to be connected to the punch 3 or to a washer 54 formed on the longitudinal end 5 thereof via 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 8 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, the winding body is expanded in principle in a manner similar to that in FIGS. 1 and 2 by 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. According to Fig. 29 and 30, the film hinges closer to the die 3 are then 53, or 58 is stretched and the film hinges lying further from the die of 3 53 and 58 ^o bent by about 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 at the same time the entire winding body 2 is 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 at 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 bar slats to assemble the hairstyle winder ^O to be pivoted only about 90 in the direction of arrow 55 8 until the longitudinal axis 7 of the winding body 3 are parallel.

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, for example with cone pieces 56, and a disc 54 holding the rod fins 8 together via film hinges 53 with a plug guide 67 for inserting the stamp 3 to be produced separately according to FIG. 41 The plunger 3 has at one longitudinal end a fitting part 68 for the plug-in guide 67 and at the other longitudinal end a coupling part 69 for engaging latching cams 70 provided at the longitudinal end of each of the bar lamellae 8. For assembly, the plunger 3 is fitted with the fitting part 68 in the direction of arrow 71 inserted into the cylindrical basket spanned by the bar fins 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. The drawing therefore speaks for itself.

Claims (20)

1. Hair roller (1) consisting of a cylindrical roller body (2), which is to be turned into the hair, of variable body circumference and of actuating means (3) for varying the body circumference as well as of a tension band (4) reaching at least from one (5) longitudinal end of the roller body (2) to the other (6), characterised thereby, that the roller body (2) consists of a plurality of rod laminae (8), which are parallel one to the other and to the longitudinal roller axis (7), and the actuating means (3) consist of a rod-shaped plunger (3), which is arranged in the longitudinal roller axis (7) with at least one cross-sectional enlargement (13; 30, 30a, 30b, 36; 44; 50; 59) and a profiling (14, 15, 16; 31, 31a, 31b, 32, 37; 46; 51 56), which is formed at the laminae (8) and to be brought into detent setting in engagement with the or each enlargement.
2. Hair roller according to claim 1, characterised thereby, that the rod laminae (8) are shaped by one of their longitudinal ends onto a longitudinal end (5) of the plunger (3) each by way of at least one respective film hinge (53) and that the opposite longitudinal ends of the rod laminae (8) display means (57) for detenting in a position at the circumference of the plunger (3).
3. Hair roller according to claim 1 or 2, characterised thereby, that the rod laminae (8) in the relieved position formed during the manufacture, in particular by injection-moulding, are pivoted about 180° away from the detented position into a direction likewise extending about parallelly to the longitudinal roller axis (7) and there lie approximately on a common cylindrical surface.
4. Hair roller according to claim 1 or 2, characterised thereby, that the rod laminae (8) in the relieved position of the film hinge (53) connecting them with the plunger (3) stand about perpendicularly and radially with respect to the plunger (3).
5. Hair roller according to claim 1 or 2, characterised thereby, that the plunger (3) is connected with a substantially circular disc (54), at the circumference of which the rod laminae (8) are shaped on by one longitudinal end by way of film hinges (53) by way of a fitting part (68) constructed as plug coupling.
6. Hair roller according to one of the claims 3 to 5, characterised thereby, that those rows of the rod laminae (8), which are remote from the film hinge, are equipped at the circumferential edges facing the respectively neighbouring lamina with detent dogs and detent grooves (57), which enable a mutual fixing of the free ends on a ring.
7. Hair roller according to one of the claims 3 to 5, characterised thereby, that a detent head (63) with detent holes (62) for the snapping-in of detent dogs (61) provided at the free ends of the rod laminae (8) is to be placed onto that free longitudinal plunger end (6), which is opposite the longitudinal plunger end (5) connected with the rod laminae (8) by way of film hinges (53).
8. Hair roller according to one of the claims 3 to 5, characterised thereby, that the free plunger end, which is associated with the free end of the rod laminae (8), is equipped as coupling member (69) with detent holes for the snapping-in of detent dogs (70) provided at the free ends of the rod laminae (8).
9. Hair roller according to one of the preceding claims, characterised thereby, that cone members (56), which together span at least one internal cone, are provided on the inward surface of the rod laminae (8).
10. Hair roller according to one of the preceding claims, characterised thereby, that the rod laminae (8) are coupled at their longitudinal ends one with the other or with the plunger (3) each time by way of two film hinges (53, 58) and that the roller circumference is adjustable through longitudinal displacement of the plunger (3) relative to the internal cone.
11. Hair roller according to one of the preceding claims, characterised thereby, that the roller body (2) consists of a frame, which is to be expanded or contracted mechanically in radial direction, with an elastic skin (9), in particular of synthetic material or rubber.
12. Hair roller according to one of the preceding claims, characterised thereby, that a bead (13), which is arranged about symmetrically to the centre line (7) of the roller body (2), is disposed on the plunger (3), that the inward roller body surface is constructed in portions as internal cone (14) with detent surfaces (15, 16) adjoining both ends for the bead (13) and that the roller body (2) is splayed in the case of arrangement of the bend (13) on the surface (16) of the smaller internal diameter as well as shrunk in the case of arrangement of the bead (13) on the surface (15) of the greater internal diameter.
13. Hair roller according to one of the preceding claims, characterised thereby, that the plunger (3) comprises a respective actuating knob (11, 12, 64) at each of both its longitudinal ends.
14. Hair roller according to one of the preceding claims, characterised thereby, that the plunger (3) displays at least one cone or double cone (30) arranged symmetrically with respect to the longitudinal roller axis (7).
15. Hair roller according to claim 14, characterised thereby, that the inward roller body surface (21), which adjoins the respective plunger cone (30) and in the same direction as this, is constructed conically (31) at least in individual laminae.
16. Hair roller according to one of the preceding claims, characterised thereby, that the plunger (3) is rotatable about its longitudinal axis (7) and at least in portions has a cross-section (44) in the shape of a dog star and that counterdogs (46) on the inward surface (21) of the roller body (2) are associated with the dogs (45) of the plunger (3).
17. Hair roller according to one of the preceding claims, characterised thereby, that the plunger (3) at its one longitudinal end (17) - in particular without actuating knob - is connected, preferably integrally with a tension band (4).
18. Hair roller according to claim 17, characterised thereby, that the tension band (4) is placed firmly on the longitudinal plunger end (17) to be drawn during the splaying of the roller body (2).
19. Hair roller according to one of the preceding claims, characterised thereby, that the plunger (3) is surrounded by an elastically mounted ring (36) and that the ring engages into an annular groove (37) of the inward surface (21) of the roller body (2).
20. Hair roller according to claim 19, characterised thereby, that the annular groove (37) is deeper in radial direction than the greatest envisaged change in diameter of the roller body (2).
