Abstract

The hair curler (1) has a hollow supporting component (2) that has two fixing portions (4) with fixing units designed and arranged to protrude in radial direction to attach the hair curler to the head. The diameters of the two fixing portions are approximately identical and greater than the diameter of the middle portion (3) of the supporting component. The fixing portions are arranged at respective ends of the hair curler. The middle portion is arranged between the ends, and designed and arranged to form a winding surface to wound-up hair.

Description

The invention relates to a hair curler for winding human hair, with a support body of a hollow formative molding made of plastic or metal, which has a central region with a winding surface for winding a hair and at both ends each have a mounting region with a comparatively larger diameter for fixing the curler on the head. The middle region has projections for engagement in the hair part to be wound up and the attachment regions have hook-shaped holding elements for fixing the curler to the head after a winding process. The support body is preferably formed open-through and has a certain gestaltgebende elasticity, but can also be designed solid, especially if it consists of metal. Such curlers are known to be used to wrap hair in curls and thus to influence the shape of the hair.

STATE OF THE ART

A curler of the type described above is from the DE 17 57 714 A1 or the US 3,533,418 known. The curler has a support body made of a hollow shape-shaping molded part made of plastic. The support body has a central region with a winding surface for winding up a hair part, followed by a respective attachment region at both ends. The middle area is concave and merges without any jump in diameter into the end areas. The middle region has projections over its entire length for engagement in the wound-up hair part, while the attachment regions have hook-shaped holding elements for fixing the hair curler to the head after completion of a winding process. The projections in the middle region can also be mushroom-shaped with a thickening at the free end. The projections in the central region and the hook-shaped holding elements have an approximately matching radial length. As a result of the continuous transition between the central region and the attachment regions and by the concave formation of the central region, the space for winding up a hair section, starting from the center of the curler in the direction of the two end regions increasingly narrows, so that at the end of a winding process there is a risk that a part of the hair to be wound is also gripped by the hook-shaped holding elements. This significantly affects the unwinding process.

Another curler is out of the DE 196 48 186 C2 known. The support body, which has the shape of a pipe section, can be provided as molded plastic molded body with corresponding openings. He has on its cylindrical periphery on a covering, which consists of a strip of hook tape of a hook and loop fastener. It is then a Haftwickler, the hooks of the hook band serve to set the tips of the hair of the hairline at the beginning of the winding on the curler. Depending on the length of the wound strand of hair forms a winding, in particular in the central region of the support body, which ensures that the hair curlers even when the hooks of the hook tape are not wound with hair in both end of the curler, do not reach the hairline on the head can. This known curler has no separate attachment means, but the end of the winding process and the holding of the hair on the hook of the hook tape as it forms the fastening device. In another embodiment, no hook tape, but a loop tape of a hook and loop fastener is arranged on the circumference of the support body. Such a velor winder additionally requires a fixing device for the determination of the curl on the circumference of the support body on the one hand and for the determination of the curler relative to the head after completion of the winding process. Such a fastening device may consist of a transverse pin or a portion of a hook band, which is used in addition to the loop tape.

The known curlers have various disadvantages in use. During winding, it can not be prevented that the strand of hair during the winding process over the entire axial length of the hair curler distributed and hair areas even laterally slip off the curler. When unwinding the lock there is a risk that especially in the end areas, the hair part initially difficult solves. This is also the case towards the end of the mid-range winding-up process. When unwinding, finally, the end portions of the hook tape come free, with the risk that previously unwound hairs are wrapped during Auswickelvorgang. The consequence of this is that hair is torn off the head when using the hair curler, because they can not be solved by a forward or a reverse rotation of the support body of this.

From the DE 40 18 202 C2 is a preferably known to be used at night Haftwickler for winding human hair, which also has a cylindrical support body and on this a covering, which consists of a portion of a hook tape. The hooks may be formed by cut loops. The unit of support body and hook band is designed to be soft and elastic overall. The support body may be a cylinder section made of foamed plastic, which is designed so narrow pores that he is able to absorb liquid and sponge-like expressible. Such an adhesive developer has similar disadvantages as already described above. The use of a Velcro tape here also brings the danger that when using the winder hair are pulled out with.

From the US 3,438,382 is a curler known, which has a constant diameter over its entire extent continuous central part and two adjacent end mounting areas. The entire middle part is provided with gripping teeth, so that the winding of the hair tips can begin at any point of the middle part. Between the ends of the central part and the attachment areas, and on the outside of the attachment areas radially projecting ribs are provided to facilitate the placement of a strip hook band on the circumference of the attachment area. The ribs, which may also be missing, have a larger diameter than the band of the hook band. The diameters of the middle part, of the ribs and of the hook band in the attachment areas are of a similar size, so that no significant diameter jump results, neither in terms of an increase in diameter nor in the sense of a reduction in diameter.

From the DE 202 07 162 U1 a permanent wave winder in the form of a cylindrical body is known, on the peripheral surface of a bristle material with radially projecting bristles for Anchoring of wound hair strands is provided. The cylindrical shaped body has constant diameter over the entire length. The bristle material on the permanent wave winder has substantially shorter bristles in the middle region of the length of the winder than in the two end regions. Due to the different radial length of the different bristles results in a stepped shoulder in the free ends of the bristles over the axial length of the winder. The bristles in the middle region can have approximately half the radial length of the bristles in the two end regions. As a result of the constant diameter of the supporting body, which is continuous over the axial length of the hair curler, there is an increased risk that the hair part to be wound up also readily reaches the area of the end regions with the comparatively longer bristles. Difficulties in unwinding is counteracted by the fact that no hook-shaped holding elements are provided for fixing the curler on the head in the end, but, as in the central region, only radially projecting bristles, so that the curlers after completion of a winding process on the head attached in another way or ., must be secured, for example by a cross pin or the like.

OBJECT OF THE INVENTION

The invention has for its object to provide a hair curler of the type described above, in which the wound into a wound hair are concentrated essentially on the central region of the curler and without additional fastening device, for. B. in the form of a transverse bar, a clip o. The like., Retains its end position of the winding process near the scalp.

SOLUTION

According to the invention, this is achieved in a hair curler of the type described above in that the attachment areas for fixing the hair curler on the head to provide a receiving space for the wound hair section have a larger compared to a smaller diameter in the central area diameter increased, and that the projections in the central region for fixing the hair tips are formed at the beginning of a winding process as spines radially projecting from the support body, whose radial length corresponds approximately to half the radial length of the hook-shaped holding elements at the attachment areas.

DESCRIPTION OF THE INVENTION

The invention is based on the idea of locally and functionally separating the winding area for winding up the hair section from two attachment areas of the curler at the hairline. The central region is formed and arranged away from the axial two ends of the support body. At both free ends a fastening area are each formed. The central area not only has a smaller diameter than the attachment areas. Rather, a diameter jump is realized between central region and fastening region. This creates a quasi coil with two projecting end flanges in diameter, which are not only a visual aid in winding the strand of hair to wind this strand of hair only in the central region. Due to the diameter jump, a space or a receiving space for the hair to be wound up is created, which can be filled by the winding thickness of the hair strand. The two attachment areas are provided on its periphery with a portion of a hook tape. It can also be arranged or formed here only adhesive projections. These adhesive projections do not come into operative contact with the wound curl, but serve to be used as a fastening device for the hair curler at the end of the winding process. At the end of the winding process, the curler is pressed against the scalp, with both attachment areas resting against the hairline near the scalp, thus ensuring that the curler retains its intended tightness on the scalp. Since the head of a human is known not to be a flat surface, but has a rounded shape, it allows the diameter jump that the attachment areas can reach the hairline. The new curler requires neither cross pins nor rubbers, clips, clips or other separate fasteners for attachment. The wound hairs are not pressed by the support body with the support surface of the central region of the scalp, but by the diameter jump creates a certain distance from the scalp, which counteracts the risk of hair breakage in the case of a perm. The end of the wound hair near the scalp is guided upwards on the curler, which is a great advantage for the volume of the hairstyle. When the hair curler is used in a warmed condition, it is very advantageous to avoid direct support on the scalp. There are no pressure points. A greater potential for the base heat is possible. The non-resting of the midsection on the scalp also has the advantage that the curled curl is located some distance from the scalp. This results in a shorter drying time, because the air can circulate between the scalp and middle area. Finally, the new hair curler has better adhesion to the head compared to known generic Velcro tape wrappers, because the hook tape areas are not covered by the wound curl. Also, the unwrapping a curl is much easier and safer with the new curlers than Velcro tape wrappers. The curler may be held in the manner of a roller with two fingers and removed by removal from the scalp, with no risk that adjacent hair would be wrapped or components of the curl with the hook tape in contact.

The projections in the middle area are only used to determine the hair tips at the beginning of a winding process. They are formed as spines projecting radially from the support body, the radial length of which corresponds approximately to half the radial length of the hook-shaped holding elements at the attachment areas. The spikes can also be realized in the form of a corrugation on the surface of the central region. By their compared to the hook-shaped holding elements shorter radial length and their other shape they hinder a rolling out of the curl in any phase of the tightening movement.

It is advantageous if the axial length of a fastening region to the axial length of the middle region is dimensioned in a ratio of about 1: 3 to about 1: 6. Also, the two attachment areas, although they are not involved in the winding of the hairline, have a certain axial length relative to the rest of the curler, so that the two attachment points of the curler can be safely reached and adhered to the winding end position on the scalp. So it does not help to choose the axial length of each attachment area relatively small. On the other hand, the absolute length of the curler also has an effect on the diameter jump and on the axial lengths of the middle region and each attachment region.

Each mounting area should be formed with a constant diameter throughout the axial length. A convex or concave design is not required because differences in this regard are bridged by the hooks of the hook tape.

The diameter jump between a diameter of the central region and the diameter of each attachment region can be dimensioned depending on the intended length and thus winding thickness of the hair part. For a wearer extra long hair is Also, a comparatively larger winding thickness of the hair part of the wound curl arise, so that in this respect a relatively larger diameter jump is required. This also applies in relation to the diameter of the middle area. As is known, there are curlers in different sizes to make the diameter of the curls different. For a wearer comparatively shorter hair and the winding thickness of the hair will be less, so that in this regard, the diameter jump may be lower. This also applies to hair curlers with a relatively small diameter. The diameter jump can be in the range between about 2 to 8 mm, also depending on the different sizes of curlers.

The middle region may be formed with a constant diameter which is of constant design over the axial length, that is to say have a cylindrical shape, so that it has a circular ring cross-section at all points of the middle region. However, it is certainly not harmful if the central region is also designed concave, that is arranged in the middle of the middle region, a comparatively smaller diameter. This is to make sure that the curl to be wound up concentrates on the center of the middle area so that it does not come into contact with the attachment areas. With such a design of the central region, the diameter jump refers to the smallest diameter in the middle of the central region in relation to the diameters of the attachment regions.

The cross section of the support body is of minor importance. Thus, the support body in its central region and / or in the two attachment areas have a circular, oval or polygonal cross-section. Preferably, however, the cross section is circular.

The surface of the middle region should be roughened, corrugated, spiked or otherwise formed in whole or in part, so that the determination of the hair tips of the wound-up hair part on the surface of the middle region is favored. In general, the design of the surface of the central region is less pronounced than the design in the two attachment regions. In the limiting case, it is also possible to provide the central region with a portion of a hook tape, which, however, does not have to extend over the entire axial length of the central region.

The support body may be designed stable, so slightly yielding, such as a molded body made of hard plastic. But it is also possible to make the support body soft and elastic, for example, to allow use of the curler in a lying position or overnight and / or to use a spongy support body and thus to allow the use of a hair fixative or other liquid.

DESCRIPTION OF THE FIGURES

The in Fig. 1 shown curlers 1 has a support body 2, which may be formed as Gestaltgebendes molding, for example, as a molded body made of plastic, metal o. The like .. The support body 2 is preferably designed hollow. In the axial direction of the support body 2 has a central region 3 and at its ends a respective attachment region 4. The two mounting portions 4 have mutually same diameter, which is designed to be larger than the diameter of the central region 3, so that the curler 1 in the form of a coil or Roller gets with both ends radially outwardly projecting edge parts. The two attachment areas 4 are preferably over their entire axial extent covered by a hook tape 5 circumferentially. Such hook bands 5 are known as part of hook and loop fasteners. They consist of a woven or knitted section with outwardly projecting spines or hooks 6. The hooks 6 can be created in particular by cut slings. The central region 3, but also the attachment regions 4 on the support body can be provided with a multiplicity of perforations 7.

Fig. 2 shows the wound position of the curler 1 on a human head 8 in the scalp 9, the remaining hair on the head 8 are not shown. It is indicated only a single wound hair, which is wound into a curl 10. It is understood that the winding process of such a curl 10 starts at the hair tips. In the middle of the central region 3, a portion of a barbed tape 11 is applied. The spines of the barbed tape 11 are formed comparatively shorter in the radial direction than the hooks 6 of the hook tape 5 in each mounting portion 4. The barbed tape 11 extends only over a certain part of the axial length of the central region. It serves to fix the hair tips there and to begin the winding process. Due to the diameter jump between central region 3 and the two attachment regions 4 it is ensured that during winding of the hair section to the curl 10 this deposits only in the central region 3 and there gets a certain winding thickness. When winding the hook tape 5 remains free in both attachment areas 4 of hair. As soon as the hair curler 1 approaches the scalp 9 during the winding process and the winding process is terminated, the hair curler 1 is pressed against the scalp. This situation is in Fig. 2 shown. The hooks 6 of the two hook bands 5 of the two attachment areas 4 engage in the hair on the hairline near the scalp 9, so that the curler 1 receives its intended tight fit near the scalp 9. Due to the diameter jump between the smaller diameter of the central region 3 and the diameter of the attachment areas 4 creates space on the one hand for a certain winding thickness of the curl 10. Nevertheless, given the increased diameter of the mounting portions 4, the possibility to get the tight fit on the head 8, too if this is rounded in wide areas. The hair curled into the curl 10 at the hairline will not be bent, but may extend radially to the head 8 between the hair root and the winding point on the circumference of the curl 10, which favors the fullness of the figure ultimately created therewith. Also remains in the Wickelendstellung still a free space and a passage space for air, so that even the scalp 9 facing part of the curl 10 can be aerated or dried when the hair is wound up in the wet state.

The curler according to Fig. 2 may have the following dimensional relationships. The central region 3 has a diameter 12 of 32 mm. The central region 3 extends over an axial length 13 of 40 mm. The two attachment portions 4 have a diameter 14 of 40 mm and each have an axial length 15 of 10 mm. The hooks 6 may extend in the radial direction by about 3 mm. The spines of barbed tape 11 can be 1.5 mm long.

The support body 2 of the embodiment according to Fig. 2 is designed as a one-piece molding. Only the two sections of the hook tape 5 and the barbed tape 11 are connected by a welded connection with the support body 2, wherein at the same time the two ends of each band section are joined together.

In the Fig. 3 illustrated embodiment shows a curler 1 in a smaller size, so provided for winding shorter hair parts on a smaller diameter. The curler 1 is formed in three parts. The support body 2 is assembled from a continuous pipe section 16 and two rings 17 over the axial length of the curler. The assembly can be favored by an adhesive or snap connection. The attached rings 17 then form the attachment regions 4 and thus also provide the diameter jump to the middle region 3. The middle region 3 can be provided with a corrugation 18 in order to favor the application of the hair at the beginning of a winding process. Here too, it is possible to provide the rings 17 with sections of hook bands 5 or to form the hooks 6 directly on the rings 17. The diameter and length relations are slightly changed here. It is a hair curler comparatively smaller size. The diameter jump is compared to the embodiment of Fig. 2 or the size shown there reduced.

Fig. 4 shows a further embodiment of the curler 1 with a support body 2, seen in its central region over the axial length 13 has different diameters 12. In the middle of the central region 3, the diameter 12 is the smallest. There may also be spines 19 or needle-like extensions provided again. The diameter rises slightly in the middle region 3 in the direction of the attachment regions 4, so that here the curled lock 10 concentrated in a special way in the middle of the central region 3, so that the hooks 6 of the affirmation area remain free during the winding process, as is useful for the attachment function. Such a curler is useful for particularly strongly rounded head sections. The same can also be achieved if the diameter jump between the diameters 12 and 14 is made comparatively large.

The use of the curler 1 is very simple and safe to carry out. At the beginning of a winding process, the tips of the wound hair to be wound using the barbed tape 11, the corrugation 18 or the spines 19 in the middle region 3 and wound there with continued winding process to the curl 10 without the risk that the hair with the hook 6 of the hook bands 5 of the attachment areas 4 come into contact. At the end of the winding process, the curler 1 of the scalp 9 approaches and there is a pressing operation to the head 8, wherein now the hooks 6 get caught on adjacent hair, which were not wound up, the head 8.

The unwinding process is also very simple. By a gringfügiges radial removal of the curler 1 from the hairline 9, the hooks 6 come free and the support body 2 can be easily roll off with two fingers engaging in the hollow cross-section fingers, only a deduction in the radial direction of the head 8 is required, counter At the end of the stripping movement, the curl 10 is released to spring back to its wrapped form.
