Description

FIELD OF THE INVENTION

The invention relates to the field of hair care and hair styling. In particular, the invention relates to a device for hair care for straightening, curling hair and / or adding volume to the hair.

BACKGROUND OF THE INVENTION

Hair styling devices are generally known and include hair straighteners, hair curlers, hot combs, and hair volume boosters.

Hair straighteners, sometimes also called hair straighteners, are used to straighten hair. These hair straighteners typically comprise two clips that are pivotally coupled to clamp a strand of hair. Each clamp contains a structured or unstructured plate (also referred to herein as the heating end or heating cylindrical element), one or both of which are heated directly or indirectly by a heater. To control the temperature of one or more plates, an additional heating control system can be used. A hair straightener is typically either powered by a mains or battery powered.

To straighten hair, a strand of hair is inserted into a hair straightener in which it is clamped between two heating ends (heated plates). In addition, the two clamps of the hair straightener can be moved from an open position in which two clamps are spaced apart from each other to a closed position in which two clamps are at least partially in contact with each other. A hinge is usually provided at the rear end of the hair straightener. This hinge connects the two clamps to each other to allow the user to rotate at least one of the clamps around the hinge axis between the open and closed positions.

Hair curlers typically comprise a heated cylindrical end of hair curlers, around which a strand of hair can be wound to provide curling. These hair curlers can either contain a handle and have a similar shape as hair straighteners, for manually curling hair, a strand of hair behind a strand of hair, or the user is provided with a set of many hair curling elements that are directly fixed to the user's head with using a clip through the hair wrapped around it.

Most of the known prior art hair styling devices are specialized devices, in particular specialized for straightening, curling or adding volume to hair. Therefore, users must have many different hair styling devices, one device for each specialized hair styling application. This, of course, is not only expensive, but also takes up a lot of space, for example, in a private bathroom.

GB 1519930 describes a portable electric hair care device that can be used either (a) as a device for curling or curling hair, or (b) for straightening hair by allowing curls or waviness to be removed, if necessary. The device contains two heating elements, each having one surface provided with irregularities and an opposite smooth surface, the means being provided for bringing either two uneven surfaces or two smooth surfaces into contact. Roughnesses of two surfaces are joined together. The heating device changes from one position to another by turning it manually by 180 °.

US 6,627,852 B1 discloses hair curlers with rotatable asymmetric heating ends. These hair curlers allow you to curl and straighten your hair using the same device. It, so to speak, provides a two-in-one solution. The user can change the layout of the device from the curling mode to the hair straightening mode, and vice versa, by turning one of the asymmetric heating ends around the axis of rotation along the length of the handle. Thus, users can easily alternate between hair straightening and curling, while still using the same device.

However, there is still room for improvement. Despite the fact that the aforementioned device, known from US 6,627,852 B1, allows curling and straightening hair using the same device, this device does not allow to be used for other hair styling methods, such as, for example, to add volume to the hair.

SUMMARY OF THE INVENTION

The aim of the invention is to provide an alternative and further improved device for hair care. The invention is defined by an independent claim. Preferred embodiments of the invention are defined in the dependent claims.

One embodiment of the invention provides a hair care device for straightening, curling hair and / or adding volume to the hair, the hair care device comprising:

- a first clamp, which extends along the first longitudinal axis and comprises a first part of the handle that is attached to the first heating end, in which the first heating end has a convex first heating surface, in which the first heating end is rotatably connected to the first part of the handle to allow the user turn the first heating end relative to the first part of the handle around the first longitudinal axis;

- a second clamp, which extends along the second longitudinal axis and contains a second part of the handle, which is attached to the second heating end, in which the first and second clips are attached to each other, and by means of the parts of the handle can be moved relative to each other between the open and closed positions; and different

- a brush plate, which contains many bristles or ribs, in which said brush plate is placed on the side of the first heating end opposite the convex first heating surface.

An embodiment can be used even for even more ways of different hair styling. In a preferred embodiment, the hair care device should be suitable for straightening, curling hair and adding volume to the hair. Increased volume at the roots of the hair can be achieved, as well as good characteristics of hair alignment and curling, using only one device and without any additional devices. In this embodiment, the hair care device provides a three-in-one solution. It allows you to straighten, curl hair and add volume to the hair using the same device. The user only has to slightly modify the layout mechanically in an easy way between the hair straightening mode, the hair curling mode or the volume adding mode. This requires only a few stages of modification.

A hair care device according to the invention generally provides a similar hair straightening device with two clips that are connected to each other and can be moved relative to each other between an open and a closed position using two different parts of the handle, with one part Handles are placed on each clip. Similar to the device shown in US 6,627,852 B1, one of the heating ends, which is referred to herein as the first heating end, is rotatably connected to a corresponding portion of the handle of the same clamp (referred to herein as the first portion of the handle of the first clamp) to allow the user to rotate the first heating end relative to the first part of the handle around the first longitudinal axis. This allows the user to switch between the hair straightening mode and the hair curling mode by rotating the first heating end.

As a departure from this, the device according to a preferred embodiment of the invention comprises a brush plate having a plurality of bristles or ribs that can act as spacing elements with respect to the scalp of the user. This brush plate is located on the rear side of the first heating end, which is located on the opposite side, on which the convex first heating surface is placed, which is used for straightening and curling.

In the mode of adding volume to the hair, the user can provide the scalp with bristles placed on the brush plate, while directing a strand of hair, the volume of which should be increased, above the second heating end of the second clip. Thus, the bristles act as a form of thermal protection of the scalp and protect the user from getting burned by one of the heating ends. Thus, consumers can easily hold the device closer to the scalp without the risk of burns. This greatly simplifies the creation of volume of hair, starting from the roots of the hair. Note that instead of bristles for this type of heat-shielding function, ribs, bulges or any other spacing elements can also be used.

Preferably, the brush plate comprises a plurality of bristles or ribs that are arranged in a matrix to form an imaginary flat surface, like a contact matrix. Instead of using small pin bristles, straight ribs can also be used that are laterally placed on the brush plate. The described imaginary surface, which is formed by the bristles of the brush plate, can also be concave. This can be done by means of bristles of different lengths or by providing a concave base plate on which the bristles / ribs are placed.

According to an embodiment, the first heating end is rotatable relative to the first part of the handle about the first longitudinal axis between the first position in which the brush plate faces the second heating end and the second position in which the brush plate is turned away from the second heating end.

In order to translate the first heating end from the first to the second position, the first heating end is preferably rotated 180 ° about the first longitudinal axis.

The first position can be used for curling. In this position, the convex first heating surface, which is located on the upper side of the first heating end, forms the outer surface of the hair care device. Said first heating surface is preferably a smooth round or semicircular surface. Then, if the clips are closed, the hair can be wrapped around two heating ends in order to create curls of hair.

If the first heating end is brought to its second position, the presented device for hair care can be used either to straighten hair or to add volume to the hair. In this second position, the brush plate is facing outward, with the convex first heating surface of the first heating end facing inward to the second heating end.

To straighten the hair, the hair strand can then be sandwiched between the first heating end and the second heating end, that is, between the convex first heating surface and the heating surface of the second heating end (hereinafter referred to as the third heating surface, see below).

To create a volume of hair from the hair roots, the brush plate may be in the second position of the first heating end in contact with the scalp of the user, while the exposed hair strand is sent over the second heating end in order to heat the hair strand and create an increased volume of hair.

Straightening, curling and giving volume, everything is done in the closed position of the clamps. In particular, for curling and giving volume, this closed position of the clamps can be fixed using a simple mechanism with mechanical locking. The difference in the layout of the device for different hair styling applications is only the position of the first heating end. Curling is performed in the first position of the first heating end, although the straightening and volumetricizing is carried out in the second position of the first heating end.

The first heating end preferably has a crescent section. On the semicircular upper side there is a smooth first heating surface, although a brush plate is placed near or attached to the flat lower side. As mentioned above, the brush plate is used "only" to add volume to the hair (in the second position of the first heating end), while a smooth semicircular first heating surface, depending on the position of the first heating end, can be used either for curling (first position) or alignment (second position).

Note that the terms “first”, “second” and “third” are not related to the total number of specific parts, but are used in this document to distinguish between similar or corresponding parts of a device in accordance with the invention.

According to another embodiment, the second heating end comprises:

- a convex second heating surface on the side that is turned away from the first heating end; and

- a third heating surface that faces the first heating end and has at least partially a concave contour that aligns with the outer contour of the first heating surface of the first heating end.

As will be better seen from the attached drawings and the detailed description of the drawings, the convex second heating surface preferably has a similar shape, the same as the first heating surface, which is located on the first heating end. This second heating surface can be used either for curling hair or for adding volume to the hair. In the straightening mode, a strand of hair is clamped between the first heating surface of the first heating end and the third heating surface of the second heating end. Since the third heating surface has a concave contour that aligns with the external contour of the first heating surface, hair can be straightened optimally. Rounded concave / convex heating surfaces that fit together, in comparison with flat heating surfaces, create an enlarged heating surface, which leads to improved hair alignment characteristics. In addition, it is important that the conjugated concave / convex heating surfaces create increased resistance to the hair sandwiched between them. This further improves the straightening characteristics compared to hair straightening devices with flat heating surfaces. However, it should be noted that preferably only part of the third heating surface, for example, the middle part, has a concave shape. The sides of the third heating surface are preferably flat. This prevents unwanted bending of the hair.

According to another preferred embodiment, the hair care device further comprises at least one mechanical end restrictive element that is configured to keep the bristles or edges of the brush plate away from the second heating end when the first heating end is in the first position and the clamps are in the closed position.

This mechanical end restrictive element prevents the brush plate from coming into contact with the second heating end (with the third heating surface). Otherwise, the brush plate may be damaged as a result of the high temperature of the second heating end. Thus, the brush plate does not get too hot. When the first heating end is rotated from its first to its second position, the heating ends can thus immediately come into contact with the scalp of the user while adding volume to the hair without the risk of burns to the scalp of the user.

According to another embodiment, the first clamp comprises a first gripping element at the free end of the first heating end to allow the user to rotate the first heating end relative to the first part of the handle, wherein said free end of the first heating end is the opposite end at which the first heating end is attached to the first part of the handle .

Said first gripping element should preferably be thermally insulated from the first heating end and comprise a heat-resistant synthetic material.

Thus, users can easily rotate the first heating end between the first and second position using the aforementioned first gripping element. This gripping element can be configured in various ways. Preferably, it has an ergonomic shape to increase user convenience. It is preferably located at the distal end of the first clamp and extends along the first longitudinal axis. Thanks to the thermal insulation of said gripping element, there is no risk of burns to the user.

According to another preferred embodiment, the second clamp also comprises such a gripping element. This gripping element will be referred to herein as the second gripping element, which is located at the free end of the second heating end. The user can thus hold both clamps at their free ends. This makes them much easier to rotate the first heating end in a safe manner.

According to another embodiment, the aforementioned at least one mechanical end limiting element is arranged on the first and / or second gripping element. In this case, the gripping elements have two functions: 1. means for rotating the first heating end between its two positions; and 2. acting as a mechanical end limit member to prevent the brush plate from coming into contact with the second heating end if the first heating end is in its first position and the clamps are brought to the closed position.

According to another embodiment, the hair care device comprises a locking mechanism for preventing rotation of the first heating end relative to the first part of the handle when the clips are in the closed position. This prevents unwanted rotation of the first heating end during use. It fixes the first heating end either in the first position or in the second position and thereby mechanically determines the two positions in an exact way.

According to an embodiment, this is preferably realized in that the first and second gripping elements have interlocking external circuits, and in that the locking mechanism is implemented by said alignment of external circuits that are joined together when the first heating end is in the second position and the clamps are in the closed position. Both gripping elements can, for example, have a matching wave-like or grooved shape. In this case, there is no need for additional parts for the implementation of the locking mechanism.

As already mentioned at the beginning, the brush plate forms one of the main features of the invention. According to an embodiment, the brush plate is thermally insulated from the first heating end and comprises a heat-resistant synthetic material.

For example, a material such as polyamide may be used. Polyamide or other plastics have low thermal conductivity characteristics, which has a great advantage in this case. As already mentioned above, the brush plate will protect the user from getting burned during the regime of adding volume to the hair. Since the heating ends become very hot during use (about 150 ° C. or higher), thermal insulation is preferred. This, for example, can be done by placing a heat-insulating intermediate layer between the brush plate and the first heating end.

Another aspect relates to user comfort provided by bristles or ribs. According to an embodiment, the bristles or ribs protrude from the brush plate, and in which the set of said bristles or ribs is flexible and has a rounded free end. Of course, all bristles or ribs can be flexible and have a rounded free end. This is for much greater user convenience.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

FIG. 1 shows an embodiment of a hair care device according to the invention. Here, the hair care device is generally indicated at 10.

The hair care device 10 comprises two clamps, a first clamp 12 and a second clamp 14. The first and second clamp 12, 14 form the main body parts of the device 10. Each clamp 12, 14 contains a handle part 16, 18 and a heating end 20, 22, which is attached to it. The first part 16 of the handle and the first heating end 20 are placed on the first clamp 12. The second part 18 of the handle and the second heating end 22 are placed on the second clamp 14. In this document, both heating ends 20, 22 are called heating plates or heating cylinders 20, 22.

In the shown embodiment, the device 10 for hair care is created in the same way as a conventional device for straightening hair. Two clamps 12, 14 are arranged to move relative to each other between the open position (Fig. 1a, b) and the closed position (Fig. 2a, b). This is usually accomplished with a hinge 24, through which two clamps 12, 14 are connected. The hinge 24 is usually located on or near the rear end 26 of the device 10. The hinge 24 allows the user to rotate / rotate at least one of the clamps 12, 14 around an axis 28 hinges. An additional spring element (not shown) can be provided that pushes the two clamps 12, 14 to their open position (Fig. 1a, b).

The two heating ends 20, 22 are heated using a heating device (not shown). This heating device is preferably integral with the heating ends 20, 22. Heating devices of this type can be made in many different ways. A commonly used induction heater or PTC heater. These heaters can either be powered by a mains supply or battery powered.

One of the central points of the invention relates to the shape and function of two heating ends 20, 22. Both heating ends 20, 22 have a generally sickle-shaped cross section and extend substantially along the longitudinal axis. The first heating end 20 extends substantially along the first longitudinal axis 30 along which the handle portion 16 also extends. The second heating end essentially extends along the second longitudinal axis 32, along which the handle portion 18 also extends.

The first heating end 20 comprises a convex first heating surface 34 on its upper side. This first heating surface 34 is preferably a smooth surface. On the rear side 38 of the first heating end 20, which is opposite to and turned away from the first heating surface 34, the heating end 20 comprises a brush plate 36. This brush plate 36 contains a plurality of bristles or ribs 40 that act as spacer elements, as will be further explained below in more detail.

The second heating end 22 is preferably heated over its entire peripheral surface. It contains a convex second heating surface 42, which is located on the outside and turned away from the first heating end 12. On the opposite side, which faces the first heating end 20, it contains a third heating surface 44. This third heating surface 44 preferably has at least at least a partially concave contour that aligns with the outer contour of the first heating surface 34 of the first heating end 20. Motivation for these matching contours will be about explained below.

Another central point is the possibility of rotation of the first heating end 20. The first heating end 20 is rotatable relative to the first part 16 of the handle around the first longitudinal axis 30. Depending on the type of hair styling to be achieved (straightening hair, curling hair or adding volume to the hair ), the first heating end can rotate between the first position (shown in Fig. 3) and the second position (shown in Fig. 4).

In the first position, which is illustrated in enlarged view in FIG. 3a, b, the first heating end 20 is arranged so that the brush plate 36 faces the second heating end 22, in particular the third heating surface 44. The first heating surface 34 then faces upward and forms the outer surface of the device 10. In this position the first heating end 20, the device 10 can be used as a device for curling hair. This is schematically shown in FIG. 6b. Since the device 10 in this case contains two external convex heating surfaces 34, 42, the hair can be wound around these two surfaces for curling. In this case, the clamps 12, 14 must be closed. To ensure manipulation, a locking mechanism may be provided that allows the user to lock the clamps 12, 14 in their closed position (FIG. 2).

If the first heating end 20 is rotated to its second position, which is illustrated in enlarged view in FIG. 4a, b, then the brush plate 36 faces upward, i.e. turned away from the second heating end 22. The first heating surface 34 in this case faces the second heating end 22, i.e. to the third heating surface 44.

In the second position of the first heating end 20, the device 10 can be used for two different types of hair styling. It can either be used to straighten hair, as shown schematically in FIG. 6a, or it can be used to create a volume of hair from the roots, as shown schematically in FIG. 6s

In order to use the device 10 as a hair straightener, hair can be pinched, a strand of hair next to a strand of hair, between two clips 12, 14, i.e. between the first and third heating surfaces 34, 44 (Fig. 6a). In this case, two overlapping contours of the first and second heating surfaces 34, 44 are most preferred. Due to the convex and concave heating surfaces 34, 44, the effective heating area that the hair passes during styling increases compared to hair straighteners with flat heating plates. In FIG. 1a, it can also be seen that only part of the third heating surface 44, namely the middle part, has a concave shape. The lateral parts of the third heating surface 44, which are adjacent to the said middle part on the left and right side, in turn, are preferably made in the form of flat surfaces. This mainly prevents bending of the hair to be styled.

As mentioned above, the device 10 for hair care can be in the second position of the first heating end 20, also be used as a device for increasing the volume of hair. As shown in FIG. 6c, the user can then direct the device to the hair roots and allow the hair strands to extend over the second heating surface 42 of the second heating end 22 despite the fact that the device 10 is in contact with the scalp of the user through the bristles or ribs 40 of the brush plate 36. The brush plate 36 in this case acts as a form of protection against burns. The bristles or ribs 40 act as spacers in relation to the scalp 46 of the user, holding the hot heating ends 20, 22 away from the scalp 46 of the user.

The brush plate 36 is preferably made of a heat-resistant synthetic material with very low heat-conducting characteristics. To prevent the brush plate 36 from becoming too hot, it can be further insulated from the first heating end 20. For example, this can be accomplished by placing a heat insulating layer between the first heating end 20 and the brush plate 36 (not shown). In this case, there is no risk for the user to get a burn. To create a volume of hair, the user can directly provide the scalp with bristles or ribs 40. This allows you to get closer to the scalp and create a volume of hair starting from the roots of the hair. User convenience can be further enhanced by providing bristles 40 with rounded ends 48 and making them at least partially flexible.

Thus, this means that the hair care device 10 according to the invention can be used for three different types of hair care devices: hair straightening, curling and volumetric hair. Such a three-in-one device is not only very practical and easy to use, but also less expensive than when buying three different devices, one for each hair styling application.

To switch between different operating modes, i.e. for turning the first heating end 20 as easily as possible, gripping elements 50, 52 can be provided on the free end 54 of the two clips 12, 14. The first gripping element 50 is preferably placed on the free end 54 of the first heating end 20. This first gripping element 50 allows the user to rotate the first heating end 20 relative to the handle portion 16. The free end 54 will mean the end of the first heating end 20, which is opposite to the end 56, on which the first heating end 20 is attached to the first part 16 of the handle.

The second gripping element 52 is located on the free end 54 ′ of the second heating end 22. Both heating elements 50, 52 may also be referred to as “cold ends” since the gripping elements 50, 52 are preferably thermally insulated from the hot heating ends 20, 22, so that they do not heat up too much and the user can touch them without getting burned.

The gripping elements 50, 52 can also be seen in the front views shown in FIG. 5a and 5b. FIG. 5a shows the front of the device 10, in which the first heating end 20 is in its first position. FIG. 5b shows the front of the device 10 in which the first heating end 20 is in its second position. As can be seen in FIG. 5a and 5b, the device 10 further comprises a mechanical end restrictive element 58, which is arranged to hold the bristles 40 of the brush plate 36 away from the second heating end 22, when the first heating end 20 is in its first position and the clamps 12, 14 are closed position. In this position, the bristles 40 are not in contact with the third heating surface 44 of the second heating end 22. Otherwise, the heating ends may be damaged. If the bristles 40 are too hot in this position, it can also be dangerous for the user as soon as he / she turns the first heating end 20 to his second position and her / his scalp is in contact with the bristles 40.

The mechanical end restrictive element 58 is preferably integral with the gripping elements 50, 52, as shown in FIG. 5a. In addition, the gripping elements 50, 52 include side walls 60, 62 that protrude relative to the sides of the gripping elements 50, 52. These side walls 60, 62 not only act as a mechanical end restrictive element 58 in the aforementioned manner, but also act as protective walls, protecting the user from coming into contact with the hot heating ends 20, 22 in contact with the gripping elements 50, 52.

Another function of these side walls 60, 62 is shown in FIG. 5b. They also act as a locking mechanism 64 to prevent rotation of the first heating end 20 relative to the first handle portion 16 when the clamps 12, 14 are in the closed position and the first heating end 20 is in its second position. This is accomplished by aligning the outer loops 66, 66 'that are provided on the edge of the side walls 60, 62. The outer loops 66, 66' of the side walls 60, 62 are articulated with each other when the first heating end 20 is placed in its second position. In this case, the random rotation of the first heating end 20 is effectively avoided.

Note that the outer contours 66, 66 'of course can be made in a manner different from that shown in FIG. 5b. The outer contours 66, 66 'may be grooved or wavy. This can also be done by means of a recess, which is placed on one of the side walls 60, 62, and a corresponding mounting element on the other side wall 60, 62.

FIG. 7a-7c and 8a-8c depict an alternative embodiment in which the brush plate 36 comprises a plurality of retractable bristles. This prevents the bristles from overheating in the position in which the bristles on the first clamp 12 face the second clamp 14, and this gives the added benefit of a smaller curl clearance, while still maintaining the advantage of achieving a sufficient distance to the scalp.

FIG. 7a shows a brush plate with bristles in the active position, and FIG. 7b shows a brush plate with bristles in the retracted position. FIG. 7c shows a hair care device with retracted bristles facing the second clip 14.

FIG. 8a shows a spiral recess of the support portion 81. FIG. 8b shows an activator 83 of bristles that is linearly movable (about 5 mm). It is activated by a spiral recess of the support portion 81 shown in FIG. 8a, around which the entire assembly rotates 180 °. Spring 85 pulls back the activator 83 of the bristles when turning back 180 °. FIG. 8c shows that when the activator 83 of the bristles is moved forward, the bristles will turn outward.

FIG. 9a-9b depict a second embodiment having retractable bristles in which the bristles move outward by vertical displacement instead of rotation. FIG. 9a shows the bristles in the retracted position, and FIG. 9b shows the bristles in the active position. The support portion 91 is similar to the support portion 81 shown in FIG. 8a-8c. When the heating end 20 is rotated, the support part 91 moves the first bristle activator part 92 to the right, against the action of the force exerted by the spring 95, causing the second bristle activator part 83 to push the brush plate upward, against the action of the force applied by the spring 99, thereby bristles 97 are pushed through holes in the surface.

From the foregoing, it is clear that the hair care device in accordance with the invention can be used for different types of hair styling needs. This can be done using the same device. Switching between different stacking modes is very easy to handle.
