Definitions

• the present invention relates to a holding device for hair, in particular a hair clip or hair clip, comprising: a first holding section; a second holding section; and a connecting portion for connecting the first holding portion to the second holding portion.
• hair clips are already sufficiently known from the prior art. They are used, for example, to clip or drape the hair.
• Conventional hair clips consist of two parallel parts made of metal, which are each connected at one end by a connecting piece in the form of a loop.
• the other free ends of the two parts are usually clad in silicone or a similarly soft material to protect hair and scalp from the sharp metal ends.
• a disadvantage of such hair clips is that they are made primarily of metal to hold the tension, which material has some disadvantages, such as breaking due to material fatigue or losing shape due to frequent use, such as bending or wearing out. Metal can also rust, which is why such hair clips are not suitable for use in the shower or in the wet.
• known metal hair clips are mostly covered with a layer of paint, which, however, peels off over time. This not only changes the visual impression of the hair clip, but can also damage the hair.
• the object of the present invention is to provide a holding device for hair which avoids the disadvantages of the prior art and ensures high wearing comfort, long durability and hair friendliness.
• a holding device for hair according to the invention in particular a hair clip or hair clip, comprises: a first clamping or holding section; a second clamping or holding section; and a connecting portion for connecting the first holding portion to the second holding portion.
• the first holding section, the second holding section and the connecting section are integrally formed from plastic.
• the hair clip according to the invention thus consists of one part.
• holding section and clamping section are used synonymously in the following.
• one-piece / one-piece or the integral production of the holding device primarily means one-piece / one-piece or integral production of the functional parts of the holding device (namely in particular the first clamping section, the second clamping section and the connecting section).
• a third holding or clamping section this is also produced in one piece / in one piece / integrally with the other clamping sections and the connecting section. Two of the clamping or holding sections can thus form the legs of a “U”, the third holding section extends approximately parallel between them.
• the connecting section is the curved section of the "U" through which the holding sections are connected to one another or in which the (non-free) ends of the clamping / holding sections converge.
• clamping sections for example an upper and a lower bow near the head
• the connecting section being stable but reversibly elastic in order to press the clamping sections together with sufficient force and thus to pinch or hold the hair.
• clamping sections also encompasses embodiments in which the clamping sections embrace or embrace the hair lying between them with or also without tension.
• An integral design means a one-piece / one-piece design of the at least three sections, for example in an injection molding process in which a mold with a cavity is used which already corresponds to the final shape of the three or more sections connected to one another.
• the at least three sections are produced simultaneously, for example, by injecting plastic into the mold cavity.
• only one mold is required for the production of the hair clip according to the invention.
• the material of the at least three sections can, but does not have to be homogeneous. The choice of material and the geometry largely determine how it works and ensure that the technical requirements, such as stability, elasticity, etc., are met.
• the hair clip according to the invention is characterized by high wearing comfort, long durability and hair friendliness.
• the present invention is based on the general idea of creating a novel hair clip which is not only comparatively easy to insert into the hair, but also allows the hair styled with it to be held in place for a long time without, for example, losing its hold when worn for a long time and not to cause unpleasant tugging when pulling out of the hair and to achieve even longer durability of the hair clip.
• the hair clip according to the invention consists of two essentially parallel parts made of solid material which converge at one end of the device and connect at the other end, the lower part (close to the head) being designed such that it adapts ergonomically to the shape of the head and the upper part (away from the head) ) Part is designed such that it has a corrugated structure, for example can have a spiral helical structure.
• the helical structure of the upper (i.e. directed away from the head) clamping section of the hair clip is so pronounced that it offers better hold of the hair than a purely smooth surface would.
• the helix structure is advantageous because it distributes the pressure evenly on the hair, which means that no impression is left on the hair. This is another type of hair clip at hand to protect the hair.
• the hair clip (hair clip or the like) is also designed so that it can be used intuitively by the user.
• the hair clip consists in particular of a single part, which is made of solid plastic. It has been shown that plastic is a more suitable material for hair clips than metal, since on the one hand it is gentler on the hair, but can still hold sufficient tension and has sufficient grip.
• the hair clip according to the invention also has a significantly longer life expectancy, which is achieved by using plastic.
• plastic By using plastic, it is possible to avoid material fatigue or material deformation after prolonged use. Another advantage is that the use of plastic as a material means that no color loss is to be expected, ie the product always remains optically in the same condition as when it was bought. Furthermore, plastic is water-repellent and therefore cannot rust, so that even when used in wet hair or when showering, there are no disadvantages for the hair or the life of the hair clip.
• plastic As the material of the hair clip according to the invention, this has a closed surface, which prevents the suction or application of dirt or bacteria and thereby enables a high standard of hygiene.
• plastic is water and sweat repellent, so that the hair clip according to the invention can also be used without problems in sports, and it can prove its advantages, in particular under heavy loads. This includes, in particular, that despite the hair being held firmly by the hair clip, no marks remain on the hair after wearing, which is achieved on the one hand through the use of plastic as a material and on the other hand through the helical structure of the hair clips Hair clip according to the invention with almost all soaps or household cleaners, whereby it can be easily cleaned even after heavy soiling.
• the hair clip according to the invention is made of plastic, it will not damage it when used with the teeth and no color or material will be split off from the clip.
• the plastic is preferably elastic and / or the holding device reversibly assumes the same shape from outside without the action of force that it had in the unloaded state.
• the plastic can be a thermoplastic.
• the plastic can be transparent, semi-transparent or non-transparent.
• metal as the material has not made it possible to produce a transparent hair clip.
• a variant of the hair clip according to the invention, namely the completely transparent variant, is thus the first proposed transparent hair clip.
• the hair clip according to the invention is more injury-proof than conventional hair clips, since it consists of one part and plastic, in contrast to metal, is an injury-proof material for hair.
• the scalp and hair can e.g. not be injured by scratching the hair clip.
• the hair clip will also break less easily because the plastic material is not brittle, has high toughness and high strength. A lot of force has to be applied before the hair clip breaks (always in the same place). Special exemplary embodiments have shown that they can be bent up to about 75% before the hair clip according to the invention breaks. This causes the long life of the hair clip according to the invention.
• the plastic material is also resistant to water, mineral acids, oil, fat and oxidizing agents.
• the hair clip is particularly gentle on the hair due to the use of plastic for several reasons. On the one hand, this consists of a single part, so that no hair is in other Can get caught in parts or clamping mechanisms. In particular, the complete absence of metal makes hair-friendliness particularly important. Dispensing with metal or a one-piece integral manufacture of the holding device from plastic means in particular one-piece / one-piece or the integral manufacture of the technical or functional components in one piece or without metal. On the other hand, a structure of the holding device without metal does not mean that, for example, decorative elements, for example made of metal, cannot be attached to the holding device. With regard to the holding device according to the invention, these variants are also to be regarded as holding devices without metal, since in this respect the decorative elements are not to be regarded as belonging to the holding device.
• the hair clip can be easily removed from the hair, which is also due to the use of plastic, as a smooth, yet strong material. Furthermore, as described above, no individual hair can get caught in the hair clip, since it is made of plastic and consists of one part, so that no individual hair can be pulled out or damaged when it is pulled out of the hair. This also leads to the fact that the hair clip according to the invention can be described as without a trace, since it leaves neither marks in the hair nor damage to the hair.
• the hair clip can be so pronounced that it does not have a shiny but a matt surface (“finish”), which means that an even better, firmer hold can be achieved in the hair, since the rougher surface holds the hair better.
• the device can therefore preferably have a structured or rough surface, in particular on the clamping sections or their mutually facing sides. This can be generated by the injection mold or by post-treatment such as roughening.
• the first clamping section and the second clamping section in particular each have a free end.
• the clamping sections of the hair clip according to the invention can also be designed such that they are thinner at the front (free) end than at the rear end, where they run together or merge into the connecting section. This optimizes the force distribution and leads to less tension at the front end, which makes the hair clip easier to open, and more tension at the rear end, which results in the desired hold. Furthermore, the optimal force distribution in combination with the optimal pressure distribution due to the helical structure of the hair clip means that the hair clip leaves no marks in the hair and is therefore “non-marking”.
• the device can be designed with or without a closure. If a closure is present, the first clamping section and / or the second clamping section can have a hook-like structure for mutually connecting the free ends of the clamping sections. For example, a hook formed at the free end of the first clamping section can be pushed or rotated under the second clamping section for closing.
• the hair clip / hair clip have a closure option made of plastic, which is formed in one piece with the at least three sections.
• the hair clip can be designed such that it has a closure.
• the hair clip can also be designed such that it has no closure.
• the closure can be designed in such a way that it works by means of a simple clamping mechanism.
• the spirally shaped upper part of the hair clip is guided under the lower part of the hair clip by a slight rotational movement to be carried out with the fingers and clamped there by the hook-like end of the upper part under the lower part of the hair clip.
• the locking mechanism works in the hair clip according to the invention by pure mechanics and without effort, namely by a pure rotary movement.
• the hair clip according to the invention thus preferably consists of one part and one material (plastic) and can have a closure.
• the fact that the hair clip is made of a plastic part also means that it is particularly gentle on the hair, since no metal parts have to be used.
• the connecting section can be U-shaped, the clamping sections each connecting to the ends of the legs of the U’s.
• the first clamping section and / or the second clamping section may have a curved shape, e.g. adapted to the shape of the head.
• the clamping or holding sections each have a side on which the hair is held or on which the hair is clamped (inside), and a side facing away from this side (outside).
• the inside has no sharp edges. Rather, all edges that lie between the inside or close to the inside and the outside are rounded to protect the hair.
• the first clamping section and / or the second clamping section can have a wave shape and / or a spiral shape.
• the wave shape serves to better hold the hair in use and to protect the hair, since the pressure on the hair is evenly distributed through the wave shape, which means that no marks are left in the hair.
• a waveform is understood to be any course with repeating increases and decreases.
• the waveform should be formed at least on the inside of at least one of the clamping or holding sections. This means that not one surface presses on the hair, but the elevations exert greater pressure on the hair lying on the inside of the holding section than in the area of the depressions. There is thus a locally varying pressure distribution on the hair along the inside of the holding section. This results in a better pressure distribution, the hair tends to stand less.
• the amplitude of the Waves can extend parallel to a plane defined by the clamping sections and / or perpendicular to the plane. However, within the scope of the invention, any structure of repetitive elevations and depressions provided on the inside is conceivable.

• the ends of the clamping sections are spaced apart along a height (pitch) or along the axis of the virtual cone (distance or height H).
• the holding device tapers overall from the first holding or clamping section to the second holding or clamping section.
