Description

The invention relates to curlers for curling human hair, containing a support body of a hollow, shaping shaped part made of plastic or metal, having a middle section with a winding surface for winding hair strands and from both ends one fastening section of a relatively larger diameter for fixing the curlers on the head . The middle section has protrusions for engaging in a wound strand of hair, and the fastening sections have hook-like retaining elements for fixing the curlers on the head at the end of the curling process. The support body is preferably made perforated and has a certain shaping elasticity, but can also be made rigid, in particular if it consists of metal. Such curlers are used, as you know, for winding locks of hair with curls and, thereby, exerting influence on shaping the hair.

Curlers of the kind described above are known from DE 1757714 A1. The curlers contain a supporting body from a hollow shaped plastic part. The supporting body has a middle section with a winding surface for winding a strand of hair, to which at one end adjoins one mounting section. The middle section is made concave and passes into the end sections without increasing the diameter. The middle section has protrusions for engaging in a wound strand of hair, while the fastening sections have hook-like retaining elements for fixing the curlers on the head at the end of the curling process. The protrusions in the middle portion can also be in the form of a mushroom provided with a thickening at the free end. The protrusions in the middle portion and the hook-like holding elements have approximately the same radial length. Due to the continuous transition between the middle and fixing sections, as well as due to the concave execution of the middle section, the space for twisting the hair strand tapers more and more from the middle of the curler towards both end sections, so that by the end of the curling process there is a risk that some of the curled hair will be caught also hook-shaped holding elements. This significantly worsens the unwinding process.

Other curlers are known from DE 19648186 C2. The supporting body, having the shape of a segment of the tube, can be made in the form of a molded body molded from plastic with corresponding holes. It has a coating on its cylindrical periphery, consisting of a strip of hook and loop fastener Velcro. We are talking about Velcro curlers, and the hooks of the hook tape serve to fix the ends of the hair strands on the curlers at the beginning of the curling process. Depending on the length of the strand of hair being wound, in this case, in particular, in the middle part of the supporting body, a coil is formed that ensures that even when the hooks of the hook tape at both end sections of the curler are not wrapped with hair, the curlers cannot reach the hair roots on the head. These well-known curlers do not have a separate fixing device, and the end of the curling process and fixing the hair on the hooks of the hook tape forms a kind of fixing device. In another embodiment, not a hook tape is located on the periphery of the supporting body, but a loop fastener. Such fleecy curlers require an additional fixing device for fixing the curl on the periphery of the supporting body, on the one hand, and for fixing the curlers relative to the head at the end of the curling process. Such a fixing device may consist of a transverse pin or a piece of hook tape used in addition to the loop tape.

Known curlers have various disadvantages when used. When winding, you can not avoid the fact that the lock of hair during the curling will be distributed along the entire axial length of the curler and even part of the hair will slide sideways with the curler. When the curl is unwound, there is a danger that, in particular, at the end sections, the hair strand will be difficult to separate at first. This also occurs towards the end of the unwinding process in the middle section. Finally, when untwisting, the end sections of the hook tape are released, and there is a danger of winding in the process of untwisting previously untwisted hair. As a result of this, when using curlers, the hair is torn off from the head, since it cannot be separated from the supporting body neither when it is rotated forward nor when it is rotated backward.

From DE 4018202 C2 known are used mainly at night hair curlers for curling hair, which also contain a supporting body and a coating on it, consisting of a piece of hook tape. Hooks can be formed by cut loops. The block of the supporting body and the hook tape is generally soft and resilient. The supporting body may be a cylindrical segment of foam made with such small pores that it is capable of absorbing liquid and can be squeezed like a sponge. Such Velcro curlers have similar disadvantages already described above. The use of Velcro tape here also raises the risk that when using curlers, hair will be torn out.

From the utility model DE 20207162 U1, there are known curlers for permanent styling in the form of a cylindrical body, on the peripheral surface of which a bristle material with radially spaced bristles for securing the wound strands of hair is provided. The cylindrical shaped body has a constant diameter over the entire length. The bristle material on the curlers for permanent styling has significantly shorter bristles in the middle section of the curler length than in both end sections. Due to the different radial lengths of the various bristles, a stepwise step arises at the free ends of the bristles along the axial length of the curler. The bristles in the middle portion may have a length equal to approximately half the radial length of the bristles at both end portions. Due to the continuous diameter of the supporting body along the axial length of the curler, there is an increased risk that the wound strand of hair will also freely fall into the area of the end sections with relatively longer bristles. The winding difficulties are eliminated due to the fact that at the end sections there are provided not hook-like retaining elements for fixing the curlers on the head, but, as in the middle section, only radially spaced bristles, so that at the end of the curling process the curlers must be fixed or fixed on the head differently in the way, for example by means of a cross pin or the like.

The invention is based on the task of creating curlers of the kind described above, in which the curled hair would be concentrated mainly in the middle sections of the curler and which would retain their position at the end of the curling process near the scalp without an additional fixing device, for example, in the form of a transverse rod, clamp or the like

According to the invention, this is achieved in curlers of the kind described above due to the fact that the fastening sections for fixing the curlers on the head have a diameter sharply increased in comparison with a smaller diameter in the middle section to create a receiving space for the curled hair strand, and that the protrusions in the middle section for the fixation of the ends of the hair at the beginning of the curling process is made in the form of spikes radially spaced from the supporting body, the radial length of which corresponds to approximately half the radial length of the hook-like holding their elements on the mounting sections.

The invention proceeds from the idea of local and functional separation of the winding section for winding hair strands from two fastening sections of the curler at the hair roots. The middle section is performed and located at a distance from both axial ends of the supporting body. At both free ends, one mounting portion is formed. The middle section has not only a smaller diameter than the fixing sections. On the contrary, a jump in diameter is realized between the middle and fastening sections. This creates a coil with two end flanges of a larger diameter, which are not only an optical aid when twisting a lock of hair only in the middle section. Due to the jump in diameter, a place or a receiving space for curled hair is also created, which can be filled with the thickness of a curled lock. Both fastening sections are provided on their periphery with a piece of hook tape. Only sticky extensions can also be located or formed here. These sticky extensions do not interact with a curled curl, but serve only for use as a fixing device for curlers at the end of the curling process. At the end of the curling process, the curlers are pressed against the scalp, both fastening sections adjacent to the roots of the hair in the area of the scalp and ensure that the curlers acquire their intended firm fit on the scalp. Since the human head, as you know, is not a flat surface, but has a rounded shape, an increase in diameter allows hair roots to be attached to the fastening areas. The curlers according to the invention do not require transverse pins, elastic bands, brackets, clamps or other separate fastening means for fastening. The curled hair is pressed against the scalp by the support body not by the surface of the middle portion, but due to a jump in diameter, a certain distance from the scalp arises, which in the case of permanent styling eliminates the risk of hair breaking. The end of the wound strand of hair near the scalp is sent to the curlers steeply up, which has a great advantage for the volume of the hairstyle. If the curlers are used in a heated state, it turns out to be very favorable that direct adherence to the scalp is prevented. There are no dents. More potential for basic heat is possible. The fact that the middle section does not adhere to the scalp also has the advantage that the curled curl is located at some distance from the scalp. The consequence of this is a shorter drying time, since air can circulate between the scalp and the middle area. Finally, the curlers according to the invention, in comparison with the known curlers with Velcro tape, have better grip on the head, since the sections of the hook tape are not covered by a curled curl. Also, the curling process with a curler according to the invention is much simpler and safer than using a curler with a Velcro tape. Curlers can be held by the type of roller with two fingers and removed by pulling from the scalp, and there is no danger that neighboring hair will also curl or the components of the curl come into contact with the hook tape.

The protrusions in the middle section serve only to fix the ends of the hair at the beginning of the curling process. They are made in the form of spikes radially spaced from the support body, the radial length of which corresponds to approximately half the radial length of the hook-like retaining elements on the fastening sections. Spikes can also be implemented in the form of corrugation of the surface of the middle section. Due to their shorter radial length and other shape than hook-shaped holding elements, they do not interfere with the process of unwinding the curl at any stage of the pulling motion.

Preferably, if the axial length of one mounting section is calculated relative to the axial length of the middle section as 1: 3-1: 6. Also, both fastening sections, although they are not involved in the process of twisting the hair strands, must have a certain axial length with respect to the rest of the curler so that both fastening points of the curler in the final position of the curler on the scalp can be achieved and observed reliably. Therefore, it is not necessary to choose the axial length of each fastening portion relatively too small. On the other hand, the absolute length of the curler affects the increase in diameter and the axial lengths of the middle section, as well as each mounting section.

Each fastening section should be made with a constant diameter continuous along the axial length. A convex or concave shape is not required, since differences in this respect are overlapped by hooks of the hook tape.

The diameter jump between the diameter of the middle section and the diameter of each fastening section can be calculated depending on the length provided and, thus, the thickness of the wrap of the hair strand. For the owner of especially long hair, a comparatively larger thickness of the wrap of the hair strand at the curled curl is also obtained, so that in this regard a relatively larger increase in diameter is required. This also applies to the diameter of the middle section. As you know, there are curlers of different sizes for curling curls of different diameters. For the owner of relatively shorter hair, the thickness of the wrap of the hair strand will also be less, so that in this respect the increase in diameter will also be smaller. This also applies to curlers of relatively small diameter. The increase in diameter can lie in the range of 2-8 mm, also depending on the different size of the curler.

The middle section can be made with a constant, continuous along the axial length diameter, i.e. have a cylindrical shape, so that in all places it has a cross section in the form of a circular ring. It will not hurt, however, if the middle section is also concave, i.e. so that in the center the middle section has a relatively smaller diameter. As a result, the curled curl is concentrated in the center of the middle section, so that it does not come into contact with the fixing sections. In this embodiment, the shape of the middle portion of the jump in diameter refers to the smallest diameter in the center of the middle portion with respect to the diameters of the fastening sections.

The cross section of the supporting body is of secondary importance. Thus, the supporting body may have a circular, oval or polygonal section in its middle section and / or in both mounting sections. However, a circular cross section is preferred.

The surface of the middle section should be completely or partially roughened, grooved, studded or otherwise in order to help fix the ends of the hair of the wound strand on the surface of the middle section. As a rule, the surface shape of the middle section is less pronounced than the shape of both fastening sections. In an extreme case, you can also provide the middle section with a piece of hook tape, which, however, should not extend along the entire axial length of the middle section.

The supporting body can be made form-stable, i.e. slightly malleable, for example in the form of a shaped body made of hard plastic. You can also make the supporting body soft and elastic, for example, to ensure the use of curlers in a lying position or at night and / or use a spongy support body, thereby ensuring the use of hairspray or other liquid.

Below the invention is explained in more detail and described using the preferred examples shown in the figures, in which

- FIG. 1: perspective view of curlers, first embodiment;

- FIG. 2: a section through the curlers of FIG. 1 in the final position of the curl near the scalp;

- FIG. 3: another embodiment of a curler of three connected parts;

- FIG. 4: another section of the shape of the curler.

Depicted in FIG. 1, the curlers 1 comprise a supporting body 2, which can be made in the form of a shaped part, for example in the form of a shaped body of plastic, metal, etc. The supporting body 2 is preferably hollow. In the axial direction, the supporting body 2 has a middle section 3, and at its ends - one fastening section 4. Both fastening sections 4 have the same diameter, which, however, is larger than the diameter of the middle section 3, so that the curlers 1 take the form of a coil or roller with protruding radially outward at both ends by edge zones. The two fastening sections 4 are preferably coated with hook tape 5 along their entire axial extent. Such hook tapes 5 are known as part of the hook and loop fasteners. They consist of a woven or knitted piece with spikes or hooks protruding outward 6. The hooks 6 can be obtained, in particular, by cutting loops. Middle 3 and fixing 4 sections of the supporting body can be provided with many holes 7.

In figure 2, the curlers 1 are shown in the curling position on the head of a person 8 in the skin zone 9, and the remaining hair on the head 8 is not shown. Only a single strand of hair is curled, curled into a curl 10. It is clear that the process of curling such a curl 10 begins at the ends of the hair. In the center of the middle zone 3 there is a segment of studded tape 11. The studs of the studded tape 11 are made in the radial direction comparatively shorter than the hooks 6 of the hook tape 5 in each fastening section 4. The studded tape 11 also extends only along a certain part of the axial length of the middle section. It serves to fix the ends of the hair there and start the curling process. By increasing the diameter between the middle 3 and both fixing 4 sections, it is guaranteed that when twisting the hair strands into curl 10, the latter is located only in the middle section 3 and acquires a certain wrap thickness there. When winding the hook tape 5 on both fastening sections 4 remains free of hair. As soon as the curlers 1 in the curling process come closer to the skin of the head 9 and the curling process is over, the curlers 1 are pressed against the scalp. This situation is shown in figure 2. The hooks 6 of both hook bands 5 on both fastening sections 4 are hooked to the hair at the roots near the scalp 9 so that the curlers 1 get their intended firm fit near the scalp 9. Due to the jump in diameter between the smaller diameter of the middle section 3 and the diameter of the fastening sections 4, on the one hand, there is a space for a certain thickness of curling of the curl 10. Nevertheless, by increasing the diameter of the fastening sections 4, it becomes possible to obtain a firm fit on the head 8, even if it has a rounded shape over wide areas. The hair curled into a curl 10 at the roots does not bend, but can pass between the roots and the curl at the periphery of the curl 10 in the radial direction to the head 8, which contributes to the volume of the resulting hairstyle. Also, in the final wrap position, there is still free space and space for the passage of air, so that air can also flow to the part of the curl 10 facing the skin 9 of the head or it can be dried if the hair is wound wet.

The curlers of FIG. 2 may have the following aspect ratios. The diameter 12 of the middle section 3 is 32 mm The middle section 3 extends along an axial length of 13 by 40 mm. The diameter 14 of both fastening sections 4 is 40 mm, and the axial length 15 of each of them is 10 mm. The hooks 6 can protrude in the radial direction by about 3 mm. The studs of the studded tape 11 may be 1.5 mm long.

The supporting body 2 in the form of execution in figure 2 is a solid shaped body. Only both segments of the hook tape 5 and the studded tape 11 are connected by means of a welded joint to the supporting body 2, and at the same time, both ends of each fastening segment are connected.

In the embodiment shown in FIG. 3, the curlers 1 have a smaller value, i.e. Designed for winding shorter strands of hair at a smaller diameter. Curlers 1 are made of three parts. The supporting body 2 is assembled from a tubular section 16, continuous along the axial length of the curler, and two rings 17. Assembly can be facilitated by means of an adhesive or snap-in connection. The put on rings 17 then form the fastening sections 4 and, thus, create a diameter jump relative to the middle section 3. The middle section 3 can be provided with a corrugation 18 to help fix the hair at the beginning of the curling process. It is also possible to provide rings 17 with segments of hook bands 5 or to form hooks 6 directly on rings 17. The ratios of diameters and lengths are slightly changed here. This is a relatively smaller curler. Also, the increase in diameter is reduced compared to the embodiment of FIG. 2 or the magnitude shown there.

In FIG. 4 shows another embodiment of a curler 1 with a supporting body 2, which in its middle section, when viewed along the axial length 13, has different diameters 12. In the center of the middle section 3, the diameter 12 is smallest. The diameter increases slightly in the middle section 3 in the direction of the fixing sections 4, so that here the curled curl 10 is concentrated in a special way in the center of the middle section 3, as a result of which the hooks 6 of the fixing section remain free during the curling, as is appropriate for the fixing function. Such curlers are suitable for particularly strongly rounded parts of the head. The same can be achieved when the increase in diameter between diameters 12 and 14 is relatively large.

Curlers 1 are very simple and reliable to use. At the beginning of the curling process, the ends of the wound hair strands with the help of a studded tape 11, corrugation 18 or spikes 19 are applied to the middle section 3 and, continuing the winding process, curl there into curl 10 without the risk that the hair will come into contact with the hooks 6 of the hook ribbons 5 fastening sections 4. At the end of the curling process, the curlers 1 come closer to the skin of the head 9, and the process of pressing to the head 8 takes place, and the hooks 6 interlock with adjacent strands of hair on the head 8 that have not been curled.

The unwinding process is very simple. Due to the slight radial pulling of the hair curlers 1 from the roots 9 of the hair, the hooks 6 are released, and the supporting body 2 can be easily removed with two fingers inserted into the hollow section from both ends, and only pulling in the radial direction from the head 8. By the end of the pulling motion, the curl 10 freed, returning to his curled form. List of reference positions:
