Description

The field of technology to which the invention belongs

The present invention relates to a hairdresser's hair curler, which includes a device for winding a strand of hair around a rod in order to perform said curling. In particular, the subject of the invention is a hairdresser's hair curler, which includes a winder, which contains:

- rod,

- a winder designed to wind a strand of hair around the rod during its rotation in a given direction,

- an engine for driving said winder,

- a device for fixing the hair, located at the far end of the rod.

State of the art

Such hairdressing devices are well known to those skilled in the art. It is also known that in order for these devices to work properly and give users the desired result, namely, to ensure the curling of a strand of hair, it is necessary to hold and guide this strand near the end of the rod when they are wound around it. For this, several technical solutions have been proposed using a special stop that would prevent the part of the hair strand located at the end of the rod from rotating around it in the process of winding this strand with the help of a winder. Thus, for example, in the documents FR 2373986 or CN 205612003, more or less flexible stops are proposed, located perpendicular to the rod. Stops of this type do provide directional movement of the hair strand, however, they also have a serious drawback, which manifests itself in those situations when the user needs to remove the hair strand from the rod, that is, to remove it. The fact is that the stop proposed in the cited documents in such cases interferes with the sliding of the strand of hair formed on the rod, and the tensile force created in this case causes a partial disruption of the completed curl. This can be detrimental to the user in that the curl of the hair strand may be partially destroyed during the strand extraction operation.

To eliminate this drawback and facilitate the removal of the hair strand formed on the rod, it was proposed to make the first type of stop movable, however, to ensure such mobility, mechanical means are required, which turn out to be too complicated and expensive, and sometimes not reliable enough.

In the patent application CN 205492908 it was also proposed to make a special recess at the end of the rod. Such a V-shaped notch does not interfere with the removal of the hair strand formed on the rod, thereby facilitating the extraction operation. In addition, this recess prevents the hair strand from rotating around the end of the rod when it is wound around this rod. However, even here there are a number of shortcomings that manifest themselves at the time of winding the strand. They consist in the fact that a situation may arise when a strand of hair comes out of the indicated recess and is not fixed inside the device. This can lead to poor quality winding of the hair strand and, accordingly, poor quality curling and even stop the operation of the device if knots form in the hair strand or if it is unsuccessfully located relative to the winder and / or rod.

Disclosure of the essence of the invention

The technical problem to be solved by the present invention is the elimination of the above disadvantages.

One of the technical problems of the invention lies in the development of a hairdresser's hair curler, which would provide a hair curl that lasts for a long time.

Another technical challenge is to develop a hairdresser's hair curler that is inexpensive and easy to design and manufacture.

Another technical problem is to develop a hairdresser's hair curler that is as reliable and safe as possible for the user.

The next technical problem is to develop a hair curler that is as ergonomic, comfortable and easy to use as possible.

Finally, the last technical problem of the invention is to develop a hairdresser's hair curler that would be as durable and reliable as possible.

To solve these technical problems, the invention proposes a hairdressing device for curling hair, including a winding device, which contains:

- rod,

- a winder configured to wind a strand of hair around the rod during its rotation in a given direction,

- an engine for driving said winder,

- a device for fixing hair, located at the far end of the rod, characterized in that said device for fixing hair contains

a plurality of pins protruding from the far end of the rod.

By "pin" here is meant a protrusion extending in the longitudinal direction, such as, for example, a tooth, a pin or a tenon. By "distal end" is meant the end of the rod that is farthest from the user's hand when holding the hairdresser's tool, as will be discussed in more detail below. A strand of hair is placed between these individual pins before it is wound onto the rod in order to prevent its rotation around the end of the rod and to ensure its directional movement during winding, in particular by blocking rotation at its root. As a result, the strand will not twist on its own. Thus, thanks to the invention, and in particular the use of a plurality of pins, it becomes more efficient to hold and guide the hair strand as it is wound around the rod. In addition, as with a comb or brush, this many pins allow you to distribute hair into small strands and detangle these strands. This is possible due to the fact that the strand is distributed evenly and cannot twist on its own. Additionally, due to the plurality of pins, simultaneous and uniform winding of all hairs on the rod is ensured, thereby preventing the occurrence of knots during winding.

In accordance with one of the preferred embodiments of the invention, the specified locking device contains at least three pins, preferably at least 10 pins, and preferably from 15 to 20 pins. In this case, during the operation of the device, the user places a strand of hair between these pins, while the specified number of pins also allows you to exert a slight tensile force on the strand of hair before winding it on the rod, thereby significantly improving the formation of this strand.

In accordance with one of the modifications, each of the pins extends in the longitudinal direction from the base, made in one piece with the specified distal end, to the top for a length of 5-25 mm, preferably 10-15 mm. Due to the presence of a plurality of pins and their sufficient length, an unexpected exit of a strand of hair from the fixing device is effectively prevented. When using this modification, the rod runs along the longitudinal axis, and each of these pins runs along the first longitudinal axis, which is parallel to the longitudinal axis of the rod, and the specified first longitudinal axis passes through the center of the specified vertex and the center of the specified base. By "top" is meant here preferably the free end of each pin, and by "base" preferably that part of the pins which is in contact with the stem. In other words, each of these pins runs in the same direction as the rod. Thus, by this configuration, the operation to extract the hair strand without any obstruction and resistance is made possible and facilitated. In addition, it is extremely convenient for the user to remove the device by moving it away from the head. It is particularly expedient that at least one of said pins, and more preferably each of said pins, has a decreasing cross-section from its base to its top, which will make it even easier to remove the hair strand like a molding bevel situation. Preferably, the base of each of the pins is a circle, and the pins will be in the form of a cone or truncated cone. In accordance with one of the particularly preferred embodiments of this modification of the invention, the tops of these pins are arranged coplanar in a plane forming an angle other than 90° with the longitudinal axis of the rod. In other words, the vertices of said pins are within a plane that is not parallel to the bar end. Suitably, said angle is between 85° and 60°, and preferably 75°.

In accordance with one of the preferred embodiments of the invention, the rod contains a heating element for heating the strand of hair in the process of winding it on the rod, which helps to maintain its shape for a long time and obtain curls. Preferably, the rod has a cap of heat insulating material, said cap forming the distal end. Thanks to this design, the skin of the scalp of the user will be protected from even the slightest danger of burns.

In accordance with another embodiment of the invention, which can of course be used in combination with one of the previously discussed options, each of the pins is made of phenylene polysulfide, which makes it possible to achieve an ideal compromise between mechanical strength, heat resistance and relative flexibility.

In accordance with one of the preferred embodiments, the specified device has a housing that encloses the specified rod. In other words, the specified rod, but, in addition, preferably, all components of the winding device are enclosed in a housing, which makes it possible to obtain an extremely compact device, safe for the user and durable, since its moving parts are protected by this housing. With this embodiment, the housing is provided with an upper opening and a lower opening connected to each other by a front opening. Preferably, each of said upper and lower openings is provided with a slot or notch. Thus, thanks to said top, bottom and front openings, the user manages to insert a strand of hair into the housing, whereby it will automatically be taken up by the winder and wound on the rod in accordance with a mode of operation, which is itself well known.

Preferably, said pins are located in the specified housing and in the specified front hole. In other words, none of the pins extend beyond the case. Thanks to this special arrangement of pins inside the case, it is possible to protect them in case the device is dropped and reduce the risk of breakage. It is expedient that said upper opening extends longitudinally from said front opening along an upper longitudinal axis, that said lower opening extends longitudinally from said front opening along a lower longitudinal axis, that said rod extends along a longitudinal axis, and that said upper longitudinal axis, the lower longitudinal axis and the longitudinal axis of the rod were coplanar in the symmetry plane of the device. In other words, all respective axes of the top hole, bottom hole, front hole, and stem are aligned on the same plane, which preferably passes through the middle of the tool and is the plane of symmetry of the tool. In this way, the strand of hair can traverse the body of the device, passing through the hair fixing device, more specifically, through the plurality of pins. At the same time, thanks to the many pins, as well as the lower and upper holes, it is possible to ensure directional movement of the hair strand in the process of winding it on the rod. In accordance with one of the preferred solutions within this embodiment, at least one of said first longitudinal axes of the pins is located coplanar in the said plane of symmetry of the device, i.e. preferably aligned with the longitudinal axis of the rod, with the lower axis and with the upper axis. In other words, at least one of the pins is located in the middle plane of the device, in which the axes of the specified upper, front and lower holes are located. By "medial plane" is preferably meant the plane of symmetry of the instrument. Thanks to this construction, it is easy to always create a slight stretch of the hair strand before winding it on the rod, while the strand passes through the upper and lower holes. The specified slight stretching of the strand of hair allows you to eliminate possible knots formed in it, as well as to guarantee high-quality winding on the rod.

According to another embodiment, which could be the subject of a separate complete invention, a hair curler includes a winder that includes:

- rod,

- a winder configured to wind a strand of hair on the rod during its rotation in a given direction, wherein said winder has an outer surface of rotation and a recess is made in the winder, passing along its surface of rotation parallel to the specified rod,

- an engine designed to drive said winder,

- a body in which an upper opening is made, where a strand of hair should enter,

characterized in that said housing additionally has a lower opening where said strand of hair should enter, and in that in the engine-on position said winder notch is aligned with said lower opening. By means of such a configuration, it is possible to substantially facilitate the introduction of the hair strand into the hairdressing device, and in particular to enable it to be gripped as close as possible to its root.

The subject of the invention is also a method of using a hairdressing device in accordance with one of the options discussed above, including:

- an input step in which a strand of hair is inserted between the winder and the rod,

- a winding step in which said winder is brought into rotation in a predetermined direction,

characterized in that it further includes a locking step performed prior to the winding step, in which a strand of hair is placed between said pins.

Implementation of the invention

It should be borne in mind that in this document the words "lower" and "upper" are used in relation to the position of the device shown in Fig.1.

Below in the text of the description, the term "device" is used to refer to a hairdresser's device for curling hair.

As shown specifically in figures 1-4, the device has a housing 1, that is, a shell in which are placed the various components of this device, and in particular the rod 21, as will be shown in detail when considering figures 5 and 9. The housing 1 is made hollow and has a free end 14 oriented during the curling operation practically in a direction perpendicular to the head of the user, and more specifically to her hairline. As can be seen in figure 2, the section of the specified body 1 is essentially oval. A winding cavity 26 is formed within the body 1, which allows the introduction of a strand of hair, before it is formed, into the outer or upper cavity 262, and then, after formation, into the inner or lower cavity 261, as will be shown in detail below. when considering Fig.5-9.

The housing 1 has an upper opening 11 extending from the free end 14 of the housing 1 into the internal volume of the housing 1. As can be seen in figure 4, the upper opening 11 has a slot or recess 10 to 50 mm long, preferably 20 to 40 mm, and even better 30 mm. This opening is sized so that a strand of hair can enter, namely when the free end 14 is placed substantially perpendicular to the wearer's head. As a result, the upper opening 11 will face the user's hairline, so that a strand of hair can enter it.

The housing 11 also has a lower opening 12 extending from the free end 14 of the housing 1 towards the internal volume of this housing 1. As shown in figure 3, the lower hole 12 has a length greater than the length of the specified upper hole 11. The length of the lower hole 12 is from 50 up to 120 mm, preferably from 50 to 90 mm, and even better 80 mm. Preferably, this hole has at least one rectangular cross section. It is also preferable that said lower opening 12 be in the form of an inverted T-shaped notch extending from the free end 14. Thanks to this special shape of said notch, it is possible, especially when a strand of hair is placed in the "smaller stroke of the letter T", to keep this strand at the bottom of said bottom hole 12 and optimize its directional movement during the winding process.

As can be seen in FIGS. 1-4, said top 11 and bottom 12 holes are connected to each other by means of a front hole 13. In other words, the top 11, bottom 12 and front 13 holes together form an opening allowing the entry of a strand of hair. and its directional movement in the process of winding on the rod. Said front hole 13 is a non-through hole made in the direction from the free end 14 of the housing 1 and connecting said upper 11 and lower 12 holes.

The device also includes a handle 3 attached to said body 1, which is designed in such a way that the user can hold the device in his hand. As can be seen in figure 1, the body 1 moves away from the handle at a slight angle. In other words, this body 1 is neither perpendicular (90° right angle) to the handle, nor is it entirely on its extension (180° straight angle). Preferably, the axis of the body 1 forms an angle substantially equal to 160° with the axis of the handle. Thanks to this solution, the ergonomics of the device is optimized, since the user is able to apply the device 1, and more specifically the upper hole 11, to his head, so that the free end 14 is practically perpendicular to his head, and at the same time hold the device by the handle 3, while the wrist will remain in a natural position.

As can be seen in FIG. 1, the instrument also includes a lever 4 for controlling the rotation and/or deactivation of the instrument, and in particular the rotation and/or deactivation of the motor 23, as detailed below. Preferably, this lever extends along the entire length of the handle 3, whereby it will be easier to activate it with any of the fingers of the hand, or even with all fingers.

In addition, the device is equipped with one or more control buttons 5, thanks to which the user can adjust various parameters of the device, for example (this example does not exhaust the possible list of actions), select the direction of rotation of the engine 23, the temperature of the rod 21 or the duration of keeping the strand in a heated state hair wound on the rod 21. Preferably, these control buttons are located on the side of the handle 3 and are separated from the lever 4.

As can be seen in figures 5-8, the device includes a winding device 2, designed in such a way as to ensure automatic winding of the hair strand and obtaining curls.

This winder 2 includes a rod or winder 21 that extends longitudinally from a proximal end 211, preferably attached to the body 1 or handle 3 (i.e. closer to the user's hand), to a distal end 212, which is preferably with a free end (that is, located at some distance from the user's hand). Preferably, said rod 21 has a cylindrical shape. The rod 21 is fixed and is preferably provided with a heating element 214, for example of the PTE (Positive Temperature Coefficient) type. As you know, heating rods make it possible to achieve more efficient curling of hair, and in particular, to obtain curls. Preferably, to reduce the risk of burning the skin of the scalp or even the user's fingers, the shaft 21 is provided with a cap 213 of a thermally insulating material, this cap will form the distal end 212.

The winder 2 also includes a winder 22, which winds the strand of hair around the rod 21 as it rotates in a predetermined direction. As shown in Figs. 5-8, the winder 22 is hollow and has the shape of a body of revolution. This winder 22 is placed coaxially with the rod 21. The winder 22 has a first longitudinal end 223 associated with a gear 242. This gear engages with a worm 241, which is driven by a motor 23, which allows you to rotate the winder 22. One of the advantages The design consists in the fact that it is possible to reverse the rotation of the motor 23, which also makes it possible to change the direction of rotation of the winder 22 to the opposite. Motor 23, gear 242 and worm 241 are one of the preferred solutions for providing the means 24 for driving the winder 22, although other variations are possible provided the scope of the invention is maintained.

As shown in Fig.5-8, the coiler 22 is preferably in the form of a cone and expands towards the distal end 212 of the rod 21. This coiler 22 is made recess (or cut) 221, passing through its surface of rotation and out to the free edge 2241 on the second longitudinal end 224 of said winder 22. This recess 221 is preferably trapezoidal, although other shapes, such as approximately cylindrical or oval, may be envisaged. Similarly, the reel 22 may have a cylindrical rather than a conical surface of revolution. The winder can also be made in the form of two wings, which can extend from the first longitudinal end 223. On the extension line of the free edge 2241, in the area of the two ends of the recess 221, there are two hooks 222.

In the switch-on position of the device (and this may be the subject of a separate invention), at the initial stage of the curling operation, the recess 221 is located on the line of the continuation of the lower hole 12 (see Fig.6-8), which allows you to enter a strand of hair into the recess 221 of the winder 22. In this case, as a result of bringing the winder 22 into rotation, one of the two hooks 222, depending on the direction of rotation of the motor 23, can capture the strand, after which its winding begins. In this case, the strand of hair moves from the outer (or upper) cavity 262, located between the outer surface of the winder 22 and the inner surface of the housing 1, into the inner (or lower) cavity 251, located between the inner surface of the winder 22 and the outer surface of the rod 21, passing through the recess 221 winders 22.

The operation of such a winder is known per se, and in particular it is known through the product marketed by the applicants under the trade name So Curls (registered trademark). One of the modes of operation of such a device is also described in patent No. 1655673. For this reason, a detailed description of this type of device is not given here.

The device also includes a hair fixing device 25 located at the distal end 212 of the rod 21. This fixing device 25 includes a plurality of pins 251 protruding from the end 212 of the rod 21. The fixing device 25 performs several functions. Firstly, this locking device 25 allows the hair strand to be guided as it is wound around the end of the shaft 21. In addition, this locking device 25 allows the curled strand to be removed without damaging it. After the winder 22 is rotated, it retracts the strand of hair, which is still guided by one of the pins 251 of the fixing device 25, ensuring its forced winding on the rod 21. Accordingly, the direction of curling of the created curls depends on the direction of rotation of the winder 22. However, it is possible, without going beyond the scope of the invention, to provide for any one desired direction of curling.

Figure 9 shows a detailed view of the fixing device 25 for fixing the hair. This locking device 25 comprises at least three pins 251, preferably at least 10 pins, and even better 15 to 20 pins. The locking device 25 shown in FIG. 9 has 17 pins evenly distributed along the distal end 212 of the rod 21. The presence of a large number of pins optimizes the retention and directional movement of the strand during its winding. In addition, the end of the rod 21 can thus become a kind of brush, which allows extremely effective combing of the hair before curling it, preventing the formation of knots in the process of making curls. Each of the pins 251 extends in the longitudinal direction from the base 2511, made in one piece with the specified distal end 212, to the top 2512 for a length of 10 to 15 mm. In other words, the length of pins 251 ranges from 10 to 15 mm. Without departing from the scope of the invention, the length of each of the pins 251 can equally well be made either fixed or, conversely, variable. Each of said pins 251 extends along a first longitudinal axis L _P parallel to the longitudinal axis L _M of the stem 21, with said first longitudinal axis L _P passing through the center of said top 2512 and the center of said base 2511. The cross section of each of the pins 251 decreases from its base 2511 to its top 2512. The base 2511 of each of the pins 251 is a circle. Thus, according to this embodiment, each pin has the shape of a body of revolution, in particular a cone or a truncated cone. Of course, it is possible to provide, without going beyond the scope of the invention, other shapes - for example, pyramidal, parallelepipedic, cylindrical, etc.

The tops 2512 of the pins 251 are coplanar in the plane P _P forming with the longitudinal axis L _M of the rod 21 an angle α other than 90°, preferably between 85° and 60°, and even more preferably equal to 75°. In other words, the length of the different pins 251 is not the same (see Fig.5). The length of the pins varies gradually from the maximum value for the pins 251 near the top hole 11, which is essentially 20 mm, to the minimum value for the pins 251, located near the bottom hole 12, which is essentially 15 mm. Due to this reduction in the length of the pins 251 from the upper hole 11 to the lower hole 12, it is possible to securely grip and guide the hair strand from its base (ie close to the root).

Each of the pins 251 is made of phenylene polysulfide (PPS). This material has exceptionally good properties, in particular with regard to mechanical strength and heat resistance. Preferably, the temperature of the pins does not exceed 70°C, while the temperature of the rod is usually from 160 to 230°C.

As can be seen in figures 1-8, these pins 251 are in the specified housing 1 and in the specified front hole 13. In other words, the locking device 25 is located entirely in the housing 1 while maintaining access to it for the user through the specified top 11, bottom 12 and front 13 holes. Thanks to this structure, it is possible to protect the locking device 15, and in particular the pins 251, and to reduce the risk of breakage if the device is dropped. The risk of burns and injury to the user is also reduced if the device is handled incorrectly, since no sharp parts protrude from its housing 1.

Figures 1-4 illustrate the alignment of the various holes. More specifically,

- the specified upper hole 11 departs in the longitudinal direction from the specified front hole 13 along the upper longitudinal axis L _S ,

- the specified lower hole 12 departs in the longitudinal direction from the specified front hole 13 along the lower longitudinal axis L _I ,

- the specified rod 21 is extended along the longitudinal axis L _M ,

while the upper longitudinal axis L _S , the lower longitudinal axis L _I and the longitudinal axis L _M of the rod 21 are coplanar in the plane of symmetry of the device.

By aligning said openings in this way, the user is able to insert the hair strand to be formed inside the housing 1 and then position the housing 1 close to and even in contact with his head, more precisely with the skin of his scalp.

As seen in FIGS. 1 and 2, at least one of said first longitudinal axes L _P of the pins 251 is aligned with the longitudinal axis L _M of the rod, with the lower axis L _I and with the upper axis L _S . In other words, at least one pin 251 is aligned with the axis of said top 11, bottom 12 and front 12 holes and with the longitudinal axis L _M of the rod 21. Thanks to this special design, it is possible to achieve exceptionally good curling results, and in particular, high-quality curls. , the shape of which is preserved over time. This is achieved due to the fact that when winding a strand of hair around the rod 21, a tensile force is exerted on it. In particular, when a strand of hair is introduced into the housing 1 through various openings, as explained above, it will inevitably encounter some obstacle, in this case at least one pin 251, as a result of which this strand will not be ideal. straight between the indicated top 11 and bottom 12 holes. In other words, the hair strand is not perfectly aligned with the median plane of the tool, ie the plane along the longitudinal axis L _M of the rod 21 and along the axes of the top 11 and bottom 12 holes. Therefore, when a strand of hair is caught by one of the hooks 222 of the winder 22, as explained above, it begins to wind around the rod 21. In this way, the strand of hair slides in various holes and rubs against at least one, and preferably several pins 251, resulting in a slight tensile force on this strand. Due to this tensile force, it becomes possible to detangle the hair and straighten the hair strand. In other words, the strand of hair undergoes a kind of tensile-type machining before being wound onto the rod 21.

The following describes the method of use, in particular the method of styling a strand of hair in the device.

To curl a strand of hair, a user operating the apparatus shown in the drawings proceeds as follows.

After the user has picked up the device by its handle 3, he turns it in such a way that the free end 14 of the body 1 faces upwards. Then he moves the device to the head, and preferably, installs it with the upper hole 11 near the skin of the scalp, so that the free end 14 is almost perpendicular to the head. The user then inserts a strand of hair between the winder 22 and the rod 21. More specifically, he inserts the strand of hair into the body 1 of the device through said top 11, bottom 12 and front 13 openings. Thus, the strand passes through the body 1, entering this body I through the upper hole 11 and the front hole 13 m, then leaving it through the lower hole 12. Taking into account the fact that the different axes of the indicated upper 11 and lower 12 holes and the cutout 221 of the winder 22 are aligned in one line, the strand of hair is placed in the winder 22, and more precisely in its cutout 221, while being between the winder 22 and the rod 21. In the process of inserting the strand of hair into the housing 1, the user also places it between the pins 251, as a result of which it is ensured its directional rotation, in particular preventing its rotation around the end of the rod during the winding process. The user can then rotate said reel 22 in the desired direction using the control button 5 (for example, to select the direction of rotation of the motor 23 and hence the reel 22) and/or the lever 4 to rotate the motor 23 and hence the reel 22. In this case, the winder will capture the strand and carry out, in accordance with the known procedure, its automatic winding on the rod 21.

Thanks to the invention, maximum optimization of the directional movement of the hair strand during this automatic winding is achieved due to the fact that, under the action of the winder 22, the strand slides between the pins 251 of the device 25 for fixing the hair. , creating a slight tensile force exerted on the hair, which allows it to be untangled and kept taut, and, on the other hand, to properly guide the hair to prevent it from twisting or rotating around the end of the rod 21.
