Description

The invention relates to a hair curler for winding human hair, having a base body made of plastic, which has a central region with a winding surface for winding a hair lot and providing a receiving space for the wound hair at both ends each having a mounting area with a larger diameter jump to fix the curler on the head wherein the attachment portions have hook-shaped holding elements for fixing the curler to the head after a winding operation. 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 102 41 772 A1 known. The curler has as a basic body a support body of a hollow shape giving plastic molding. 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 central area is cylindrically shaped and merges into the end areas with an abrupt diameter jump - that is, without rising transitions. The central region has projections for engagement in the hair section to be wound up, while the attachment regions have hook-shaped retaining elements for fixing the hair curler to the head after completion of a winding process.

Another curler is out of the DE 17 57 714 A1 known. Also, this curler has a support body of a hollow shape giving plastic molding. The support body has a central region with a winding surface for winding a Hair section, followed by a fastening area at both ends. 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 as well as by the concave formation of the central region, the space for winding up a hair lot, starting from the center of the curler towards 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. Again, the support body of this curler is designed as a largely rigid element, and thus designed neither squeezable, still liquid receptive.

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 circumference 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 particularly winding in the middle region of the support body, which ensures that the hair curlers even when the hooks of the hook bands 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 band 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 curler distributed and hair areas even laterally slip off the curler. When unwinding the curl, there is the danger that, especially in the end regions, the hair part initially becomes more difficult to loosen. This is also the case towards the end of the mid-range winding-up process. When unwinding finally come the end portions of the hook band 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.

OBJECT OF THE INVENTION

The invention has for its object to provide a curler of the type described above, which is relatively inexpensive to produce and yet additionally has several advantageous performance characteristics. In particular, the new curler should be at least partially suitable for the limited absorption of a liquid, preferably in the form of water or a hair setting.

SOLUTION

According to the invention this is achieved in a hair curler of the type described above in that the central region of the hair curler consists of a particular cylindrical portion of foamed plastic, and that the attachment areas are made with the hook-shaped holding elements as separate parts and connected to the central region.

DESCRIPTION OF THE INVENTION

The invention is initially 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 on the hairline. The central region is formed and arranged away from the axial two ends of the base body. At both free Ends are each formed a mounting area. The central area not only has a smaller diameter than the attachment areas. Between mid-range and mounting area a diameter jump is realized. 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 band. 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 curler requires for fixing neither cross pins nor rubbers, clips, clips or other separate fasteners. The wound hairs are not pressed by the main body with the support surface of the central region on 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. The non-resting of the midsection on the scalp also has the advantage that the curled curl is located some distance from the scalp. Also, the unwrapping a curl is much easier and safer in the curler 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. In that regard, the new curlers on the state of the art, ie he retains the local advantages.

The new curler is much easier and cheaper to produce. The curler is or can in any case from several separately manufactured parts be joined together. It is provided a central part, which essentially forms the central region of the curler and consists of a particular cylindrical portion of foamed plastic. The fastening parts represent separate parts that form the attachment areas with the hook-shaped retaining elements. The fasteners are connected to the middle part. This can be done by the manufacturer of the curler but only at the user. The compound can be carried out solvable or insoluble.

The attachment regions can be connected to the central region in a positive and / or non-positive connection or be. Thus, a plug connection using appropriate design and provision of appropriate properties, in particular of friction and adhesion forces, makes sense. Even adhesive joints are useful.

The attachment areas or the fastening parts may have ring-shaped or disk-shaped molded parts made of foamed plastic. Since the central region or the central part made of foamed plastic, so foam, exists, all essential elements are soft and elastic yielding. The new curler can also be used as a sleep winder at night. It also has the added benefit of being used as a travel winder because it compresses so that it only requires a small amount of storage during transportation when traveling.

The foamed plastic is elastically compressible and formed liquid absorbable. Some or all of the elements may also, in use, absorb a liquid in a limited manner. Here, in particular, the use of a hair fixative is intended.

Each attachment region may be formed with a constant diameter throughout the axial length. Also, the central region may be formed with a constant over the axial length continuously shaped diameter, so have a cylindrical shape, so that it has a circular ring cross-section at all points of the central region. However, it is certainly not harmful if the middle region is slightly reduced by the winding of the hair tresses in the 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.

The attachment regions can be formed as tubular sections of the foamed plastic, whose outer peripheral surface is covered with a band having the hook-shaped holding elements. The items can be plugged together in a simple manner. Worn or damaged parts can also be easily replaced later.

The diameter jump between the central region and the attachment areas should be at least about 4 mm in order to create a sufficient for the winding of a hair strands receiving space without the coiled curl is applied to the scalp.

The middle region should be formed with a constant diameter or cross section that is constant over the axial length. The base body should have a circular, oval or polygonal cross-section in its middle region and / or in the two attachment regions. The middle region can be permanently connected to the two attachment regions, in particular adhesively bonded.

The cross-section of the mid-range is of minor importance. Thus, the central region and / or the two attachment regions may have a circular, oval or polygonal cross section. Preferably, however, the cross section is circular.

DESCRIPTION OF THE FIGURES

The curler 1 shown in Fig. 1 has a coil-like base body 2, which is formed as a whole while giving shape, but in itself soft, elastically yielding molded part, for example as a molded body made of foamed plastic. The main body 2 is essentially composed of three parts or joined together. A middle part 3 forms a central region 4 of the hair curler 1. With the middle part 3, a fastening part 5, forming a fastening region 6, is connected at both ends. The fastening parts 5 are covered on their periphery with a strip 7, which carries a plurality of outwardly projecting hook-shaped holding elements 8. The central portion forming the central portion 4 has a smaller diameter than the two fastening portion 6 forming fastening parts 5. The diameters are coordinated and are used to provide a receiving space 9 for winding a strand of hair to a curl 10th

From Fig. 2 it can be seen that the central region 4 forming central part 3 has a cylindrical continuous cross section, that is made for example by cutting to length corresponding sections of an endless foam tape with a circular cross-section. In the same way, the mounting portion 6 forming fastening parts 5 are also made by cutting such an endless strand bead of foamed plastic and each occupied on its cylindrical circumference with a strip 7 with the holding elements 8. To form a curler 1, a middle part 3 with two fastening parts 5 is permanently connected via two adhesive layers 11. The middle part has a diameter 12 and an axial length 13. Each attachment part 5 has a diameter 14. The diameter 14 is at least 4 mm larger than the diameter 12 in order to form a sufficiently large receiving space 9 for the curl 10. The diameter 12 merges into the diameters 14 to form a sudden abrupt increase in diameter to ensure that the curl 10 is wound only on the middle part 3 in its central region 4, but not on the circumference of the fastening parts 5. By the formation of the central part. 3 made of foamed plastic, this central part has on its peripheral surface a sufficient roughness to form a grip for the hair tips of the strand when winding to the curl 10. When winding, it is not harmful if the diameter 12 of the middle part 3 is slightly pressed or reduced.

Fig. 2 also shows the situation of the curler 1 in the attached to the head 15 in the scalp 16 position. It can be seen that the two fastening parts 5 with their attachment region 6 catch on the hair (not shown) on the scalp 16 so that the curler 1 experiences a sufficient seat on the head 15 without the curl 10 being appreciably compressed or unfavorably deformed becomes.

Fig. 3 shows in a cross section a further embodiment of the hair curler 1. The middle portion 3 forming the central region 4 here has a comparatively larger axial length and thus extends over the entire length of the curler 1. The middle region 3 can be formed from a cross-sectionally continuous foam material or, as shown here, from a tubular material, which, however, preferably has a considerable thickness. The two fastening parts 5, which form the fastening region 6, are designed as an annular body made of foamed plastic. The parts are inserted into each other and are held together by appropriate static friction forces. The additional application of a bond is not required, but possible.

In the embodiment according to FIG. 4 , the middle part 3, which forms the middle region 4, again consists of a section which is created by cutting to length a cylindrical string made of foamed plastic. The two mounting portions 6 forming fastening parts 5 are also made of foamed plastic, but are here designed as moldings. They are on their cylindrical circumference, as in all embodiments, covered with a strip 7, the holding elements 8 carries. Depending on an adhesive layer 11 ensures a permanent connection between the middle part 3 and the fastening parts. 5

Fig. 5 shows a further embodiment of the curler 1, in which the middle part 3 is held with the two fastening parts 5 by a plug connection. The central part 3 is formed here from a portion of a tubular shaped plastic cord, while the fastening parts 5 are made as a molded body with the apparent from Fig. 5 design. Each fastening part 5 has a groove 17 which serves to receive the tubular central part 3. The middle part 3 has a bore 18 into which a projection 19 of each fastening part 5 protrudes or is inserted. In this way, a relatively large surface for the static friction of this connector is created or used.

In all embodiments, at least the central portion 4 forming central part 3 made of elastically flexible foamed plastic, which is thus compressible, so that the curler 1 can be worn at night as a sleep winder. It is useful, although the fasteners 5, apart from the strip 7 with the holding elements 8, made of foamed plastic, so that the main body 2 is a total compressible. This also creates the advantage that the curler 1 can also be used as Reisewickler with little storage space in the compressed state.

The formation of the foamed plastic is chosen such that it is suitable for receiving a liquid, for example water, a hair setting agent or another treatment liquid.

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-up hair are placed in the central region 3 and wound there with continued winding process to the curl 10 without the risk that the hair come into contact with the holding elements 8 of the strips 7 of the attachment regions 6. At the end of the winding process, the curler 1 of the scalp 16 approaches and there is a pressing operation on the head 15, wherein now the holding elements 8 on adjacent hair parts that were not wound up, get caught on the head 15.

The unwinding process is also very simple. By a slight radial withdrawal of the curler 1 from the hairline, the holding elements 8 come free and the main body 2 can be easily roll off with two fingers attacking at both ends, wherein only a deduction in the radial direction of the head 15 is required, Towards the end of the peeling movement of the lock 10 is released so that it springs back into its wound shape.
