Description

FIELD OF THE INVENTION

The present invention relates to the field of technology of hairdressing devices for curling hair strands, in particular, such devices that have a device for automatically winding strands to perform its curling.

State of the art

Such hairdressing devices for curling hair strands with a device for automatically twisting the strands to perform its curling are already known to specialists in this field of technology. Examples of such devices are described in patent applications published under the numbers FR 2373986 A1, DE 2816289 A1, WO 2009077747 A2, WO 2012080751 A2, WO 2013186547 A1. According to this type of design, the hairdressing device comprises a housing containing a wraparound chamber having an input hole for inserting a strand of hair, a rod located in said winding chamber and a wraparound configured to wind a strand of hair around the shaft.

In patent application FR 2373986 A1, the wraparder has a helical shape with teeth, which, when the device is turned on, allows the hair strand to be caught and wound around a heated shaft.

In patent application DE 2816289 A1, the wrapper is in the form of a cylinder located coaxially around a portion of the rod in the wrap chamber of the housing. The rod contains a conical head elongated outward from the wrapper and the wrap chamber of the housing. The curler includes a recess with a hook, which makes it possible to wind the strands around the curler and around the conical head of the rod when moving the hairdresser to the hair roots.

Mentioned hairdressing devices for curls described in FR 2373986 A1 and DE 2816289 A1, are difficult to use and not ergonomic. In addition, they do not provide effective hair curling, since the curled hair is not located near the shaft, which is necessary for proper curl formation.

In patent application WO 2009077747 A2, the body of the hairdresser device comprises a slot made along the wrap chamber through which a strand of hair passes for wrap around the shaft. The side guide plates form a V-shaped element and are located longitudinally outside the slot for inserting a strand of hair. The wrapper is in the form of a disk located around the rod. The size of the disc exceeds the size of the case, so that it passes through the slot and guide plates. The disk has a radial recess extending onto its peripheral contour and forming a hook, so that the recess can be located across the slot and between the guide plates, which facilitates the placement of the hair strand in the recess to capture the specified strand. After the strand is in the correct position in the recess, it is wound around the rod in the wrap chamber from the roots of the hair to the tip of the strand. The design of the specified winder provides twisting of the captured strands on both sides of the disk, which creates a tensile force on the hair during winding and, therefore, causes a risk of damage. In addition, with such winding on both sides of the disk, the strand can be easily pinched in the wrap chamber of the housing. The specified design, in addition, is too cumbersome.

In patent application WO 2012080751 A2, a hairdresser for curling is a pair of tongs formed from two handles. The housing is mounted at the end of one of the two handles and has an opening slot extended longitudinally along the housing in the direction of the wrap chamber, with which said slot is connected. The housing contains external guide elements located outside the slot, having a V-shape, and providing direction of the hair strand for its insertion through the slot into the wrap chamber. As in the hairdressing device described above in document WO 2009077747 A2, the wrapper is made in the form of a disk with a hook-like shape, which passes through the slot so that it is in position between the guide elements. The second handle at its end contains a second body having a section for accommodating the guide elements and a support surface configured to push the strands of hair guided by the guide elements toward the slot so that the wrapper grips said strand to wind it around the shaft. The specified design also has significant overall dimensions. In addition, this design is complex, which complicates its introduction into mass production and increases its cost.

In patent application WO 2013186547 A1, as in patent application WO 2012080751 A2, the housing forms a wrap chamber in which a rod extends, one end of which is attached to the housing and the other end is free and abuts against the outlet opening to which the wrap chamber exits. The wrapper is also made in the form of a disk with a recess forming a hook, which allows you to grab the strand so that it is wound around the rod. In the first embodiment, the housing comprises a large inlet opening configured to place the strand in the wrap chamber. In a second embodiment, the housing comprises an insertion slot elongated in the longitudinal direction and communicating with the wrap chamber above the rod, the guide elements being arranged in the form of a V-shaped element outside the slot so as to facilitate placement of the strand opposite the slot. According to these various options, the hairdressing device for curling contains an input device configured to push the strands inside the input hole or the input slot and place it in a recess on the disk. The specified design is complex, while it uses a significant number of parts that impede its production and increase production costs. In addition, this design also increases the overall dimensions of the device.

Disclosure of the invention

The main technical problem to which the present invention is directed is to create a hairdressing device that provides an easy grip of a lock of hair for winding, and while eliminating the aforementioned disadvantages of hairdressing devices for curling the prior art.

Another technical problem to which the present invention is directed is the creation of a hairdressing device for curling, which provides effective hair processing and at the same time is easy and practical to use.

Another technical problem to which the present invention is directed is to prevent pinching or tangling of the strand inside the wrap-around case and to ensure the formation of proper curls without damaging the hair.

Another technical problem to be solved by the present invention is directed, is to create a device that provides curling hair strands along almost its entire length without reducing the effectiveness of the hairdressing device and without risk of burning the hair roots.

To solve these technical problems, the present invention relates to a hairdressing device for curling hair strands, also called a hairdressing device for curling. The hairdressing device includes a control handle elongated in the longitudinal direction along the first axis X1, and a housing attached to the control handle. The control handle may take a variety of aesthetic and ergonomic shapes to allow proper grip.

The housing comprises a wraparound chamber having the shape of a body of revolution formed around the second axis X2, wherein the first axis X1 and the second axis X2 define the plane P. The housing also contains an insertion slot elongated along the housing in the plane P more or less parallel to the second axis X2 and exiting in the wrap chamber, while a strand of hair is inserted into the wrap chamber through the specified slot. The specified slot is located on the housing from the side opposite to the position of the control handle. The housing also contains an outlet made in one of its two lateral sides, onto which the wrap-up chamber enters.

It should be noted that the hairdressing device includes a rod having one end attached to the body and one free end located near the outlet, and elongated in the wrap chamber along the third axis X3 defined in the plane P passing through the second axis X2 and through the slot . Preferably, the slot is located symmetrically with respect to the indicated plane P. In addition, the third axis X3 is inclined relative to the first axis X1 at an angle α so that the free end of the rod is more distant from the control handle than the fixed end of the rod.

In addition, the hairdressing device comprises a hollow wound wrapper having a surface of revolution about the third axis X3 and located around the shaft with the first gap in the wrap chamber coaxially with the shaft along the third axis X3. The wrapper is rotatable in at least one direction along the third axis, preferably in both directions of rotation. The wrapper comprises, on its surface of rotation, engagement means configured to grab the strand in the initial position of the wrapper and bring said strand into rotation during rotation of the wrapper. In addition, the wrapper is capable of sequentially gripping or engaging the closest tip of the strand, simultaneously wrapping the strand around the rod and said wrapper, and subsequently wrapping the entire specified strand around the specified rod during its rotation.

An advantage of this design of the hairdressing device according to the invention is that this design allows you to insert the strand into the insertion slot, positioning it at an angle relative to the rod and the wraper, then insert the lock into the engagement means on the surface of rotation of the wraparound without the need to tilt the lock relative to the slot. This greatly facilitates the control of the device, the user inserts the strand into the slot, holding the control handle naturally without any difficulties in placement, then presses the outlet to the hair roots so that the end of the hair strand located near the roots is in engagement means.

In addition, the design of the hairdressing device according to the invention provides for the separation of the wrap chamber into two concentric chambers: an inner chamber formed by the first gap between the rod and the wraparder, and an external chamber formed by an external gap relative to the wraparound inside the wrap chamber. This ensures that the hair strands are wound simultaneously around the shaft and the wraparound. The wraparound surrounding the rod along its length has a wrap diameter greater than the wrap diameter of the rod, which ensures that the hair is wound around the wraparound with minimal tensile force. Consequently, there is very little risk of ruining your hair. Moreover, the longitudinal shape of the shaft and the wraper allows you to wind a lock of hair on a relatively large surface, which prevents any pinching of the hair.

In one embodiment of the hairdressing device according to the invention, the angle α is in the range of 50 ° to 80 °, preferably 70 °.

In one embodiment of the hairdressing device according to the invention, the second axis X2 is perpendicular to the first axis X1. According to this configuration, the housing is perpendicular to the control handle, while the rod and the wrapper are tilted in the wrap chamber. In one embodiment of the hairdressing device according to the invention, the second axis X2 and the third axis X3 are parallel to each other, preferably coincide. The specified configuration allows you to hold the rod and the winder on the axis of the wrap chamber of the case and tilt the case relative to the handle, while maintaining the advantage, which consists in facilitating the placement of the hair strand in the slot and in the engagement means of the wrapper. In addition, numerous options may be provided without departing from the scope of legal protection of the invention. Thus, in alternative embodiments of the hairdressing device according to the invention, the second axis X2 is inclined relative to the first axis X1 on the same side as the third axis X3, by an angle ϕ between the angle α of inclination of said third axis X3 and an angle of 90 ° ( α <ϕ <90 °).

In one embodiment of the hairdressing device according to the invention, the wrapper comprises a free edge located on the side of the free end of the shaft. In addition, the wrapper comprises a recess forming the said engagement means, elongated on the surface of rotation and extending to the free edge, said recess allowing the strand to penetrate into the first gap between the rod and the wrapper in the initial position of the wrapper. According to this embodiment, the gripping means are formed on at least one of the two ends of the recess intersecting with the free edge, preferably at both ends. Said gripping means are preferably in the form of hooks. If the rotation of the wrapper is carried out in only one direction, only one hook can be made. Preferably, the spinner is rotated in both directions along the third axis X3, and the two hooks are located opposite each other at the level of the two indicated ends of the recess. Preferably, according to the indicated embodiment, the recess has a trapezoidal shape with a small base adjacent to the free edge. However, options for the shape of the recess may be provided, for example, round or oval.

In one embodiment of the hairdressing device according to the invention, the wrapper has a cylindrical shape elongated along the third axis X3. In one preferred embodiment, the wrapper has a conical shape elongated along the third axis X3, with the conical shape expanding toward the free end of the rod.

In one embodiment of the hairdressing device according to the invention, the opening slot comprises two walls elongated longitudinally in the direction of the second axis X2 and forming a V-shaped element between them, allowing easy penetration of the strand into the wrap chamber. Thus, in contrast to the prior art, providing additional elements located outside the slot and forming a V-shaped element, the present invention is made with the possibility of embedding guide means directly into the thickness of the housing, which can significantly reduce the overall dimensions of the hairdressing device.

Preferably, in said embodiment, the slot comprises a longitudinal end portion located on the opposite side with respect to the position of the outlet opening and having two walls interconnected and forming a solid V-shaped element with a V-shaped base, rounded and configured to direct and extend the strands into the time it is wound around the rod and wraparound. The specified longitudinal section is located on the housing in front of the rod and the wraparound. This design also provides a reduction in any tensile force on the strands during its winding around the winder and the rod. According to one embodiment, the slot contains a longitudinal end portion located on the opposite side from the position of the outlet opening and having two walls connected to each other and forming a base, curved to a greater or lesser extent in the form of a spoon and configured to direct and extend the strand during it winding around the rod and wrapper. The specified longitudinal section is located on the housing in front of the rod and the wraparound.

In one embodiment of the hairdressing device according to the invention, the opening slot comprises two walls elongated longitudinally in the direction of the second axis X2 and both having ribs located in the transverse direction relative to the second axis X2. These ribs are distributed along each wall and allow the penetration of the strand into the wrap chamber. The advantage of these ribs is that they form linear contacts between the slot and the strand of hair during its insertion, which reduces friction and reduces the risk of pinching the strand at the level of the slot. Preferably, according to the indicated embodiment, each of the ribs has the shape of a disk part, which allows to gradually reduce the cross section of the slot passage similar to the V-shaped element formed between the two indicated walls, and, therefore, allows the strand to be guided during its insertion into the specified slot. Other shape options for these ribs may also be provided, also providing a reduction in the cross section of the slot passage, for example, a triangular shape. Preferably, according to said embodiment, the ribs on each wall have different sizes relative to each other and are made with different distributions on each wall.

In one embodiment of the hairdressing device according to the invention, the opening slot comprises two walls elongated longitudinally in the direction of the second axis X2 and both having wave-shaped surfaces made along these walls. These undulating surfaces allow easy penetration of the strand into the wrap chamber. The advantage of these undulating surfaces is that they reduce the contacts between the slot and the hair strand during insertion of the strand, while friction is reduced and the risks of pinching the specified strand at the slot level are reduced.

In another embodiment, the slot combines the characteristics of at least two of the three listed embodiments, namely the presence of two walls forming a V-shaped element, and / or the presence of wavy surfaces on two walls, and / or the presence of ribs on these two walls and the presence of the area in which the two walls are interconnected and form a solid V-shaped element. Each of these various characteristics is a guide means located in the slot and allowing penetration of the strand into the wrap chamber. Of course, other options for guiding means may be provided that do not go beyond the scope of the legal protection of the invention.

In one embodiment of the hairdressing device according to the invention, the device comprises a fixed foot located at or near the contour of the outlet opening in front of the free end of the shaft. The shape of the fixed foot is made relative to the free end of the rod with the possibility of blocking the rotation of the strand around the rod without the risk of its going beyond the specified foot during rotation of the wringer and facilitating the removal of the curl along the rod of the strand after curling. The advantage of this fixed foot is that it simplifies the design of the hairdressing device compared to significantly more complex existing systems of the prior art, as, for example, in the case of the device described in patent application WO 2012080751 A2, in which a retractable foot provided in motion by drive means to move it to the active blocking position of the strand at the level of the contour of the outlet, or, conversely, to an inactive position that allows you to remove Avita strand.

Preferably, the fixed foot is perpendicular to the third axis X3 and parallel to the plane P. Furthermore, the fixed foot has at least one lateral blocking side, such that a straight line d1 passing through the base of the lateral blocking side and intersecting the third axis X3 in the perpendicular direction, together with the specified lateral blocking side, formed an angle β ranging from 0 ° to 35 °, preferably 25 °. This configuration has the advantage that the strand of hair slides toward the base of the fixed foot rather than towards the end thereof, which avoids the strand extending beyond the specified foot during winding the strand.

Preferably, the fixed foot is perpendicular to the third axis X3 and parallel to the plane P. Furthermore, said foot is elongated from the peripheral contour of the free end of the rod in the direction of the third axis X3 to a height h1 ranging from 6 mm to 18 mm, preferably 12 mm. This also avoids the exit of the strand beyond the limits of the fixed foot during winding and does not adversely affect the removal of the curled strand.

Preferably, the fixed foot is located perpendicular to the third axis X3 and parallel to the plane P. Furthermore, said foot is removed relative to the free end of the rod by a distance e1 ranging from 1 mm to 5 mm, preferably 3 mm. This also allows you to achieve a good combination of the ability to lock the strand during its winding around the rod without the risk of going beyond the fixed foot with the ability to properly remove the curled strand without the risk of stretching.

Preferably, the rod has a diameter D ranging from 20 mm to 25 mm, preferably 22 mm, in case the fixed foot has these characteristics.

Preferably, the fixed foot comprises an inner side opposite the free end of the shaft. The specified inner side has a curved shape, ensuring the maintenance of a curled lock of hair when it is removed through the outlet. The inner side contains a lower end adjacent to the contour of the outlet and elongated in the form of a more or less pronounced beak, which makes it possible to avoid the passage of curled locks under the fixed foot during its removal and blocking

Preferably, according to the indicated embodiment of the hairdressing device, removable locking means are arranged between the fixed foot and the contour of the outlet. The advantage of this design is that the foot can be replaced with another foot with a slightly different shape, for example, to better adapt the hairdresser device to the type of curled hair.

According to the invention, the hairdressing device comprises heating means adapted to heat a strand of hair inside the wraparound chamber. Preferably, the heating means are located in the rod. However, it may be provided that the heating means are arranged in the wrap chamber to heat the strand during its wrap around the shaft and the wraparound.

In one embodiment of the hairdressing device according to the invention, the housing further comprises an inner casing located in the wraparound chamber around the wound wrapper with a second gap relative to the wound wrapper. The inner casing continues to direct the strand of hair inside the wrap chamber toward the wraparound after it passes through the slot. It also allows you to hold the strand inside the case around the wraparound without the risk of its distribution along the wraparound chamber.

The implementation of the invention

In the following, the same reference numbers are used to explain identical characteristics in various embodiments.

In the following, the term “device” is used to mean a hairdressing device for curling according to the invention, unless otherwise indicated.

In FIG. 1 device 1 comprises a housing 2 and a control handle 3. The device 1 is electrically connected to the power source by means of an electric cable 4 and contains control buttons 5, 6, providing the inclusion of heating means and means for bringing the rotator into rotation, described below in more detail.

As, in particular, illustrated in FIG. 2-4, the control handle 3 is elongated in the longitudinal direction along the first axis X1.

As illustrated in FIG. 1-4, the housing 2 contains a slot 7, allowing the insertion of a strand of hair (not illustrated) in the wrap chamber 8 formed inside the housing 2, in which curling of the specified strand is performed. The housing 2 from the front side 2b contains an outlet 9 through which the strand is removed or removed after curling. The wrap-up chamber 8 has a more or less cylindrical shape of a body of revolution formed along the second axis X2 corresponding to the longitudinal direction of the housing 2. The first axis X1 and the second axis X2 are perpendicular to each other and define the configuration illustrated in FIG. 1-3 plane P, which is a plane of symmetry of the housing 2, as well as the control arm 3. The slot 7 is located in the indicated plane P in the housing 2 from the side opposite to the position of the control handle 3.

As illustrated in FIG. 1-3 and 6, the device 1 comprises a rod 10 containing a fixed end 10a connected to the housing 2. The rod 10 also contains a free end 10b located near the outlet 9 in the wrap chamber 8. The rod 10 is elongated in the longitudinal direction inside the wrap chamber 8 along the third axis X3, which together with the first axis X1 forms an inclination angle α ranging from 50 ° to 80 °. Preferably, said inclination angle α is 70 °. The advantage of tilting the rod 10 is that it allows its free end 10b to be positioned further away from the end 3a of the control handle 3, which facilitates the placement of the strand for winding it, as described in more detail below. The third axis X3 is defined in the same plane P illustrated in FIG. 1-3. The slot 7 is located symmetrically with respect to the indicated plane P, as is, in particular, illustrated in FIG. 3 and 4.

As illustrated in FIG. 1-3, 5 and 6, the device 1 contains a wrapper 11, which is hollow and having the shape of a body of revolution around the third axis X3. The coiler 11 is located coaxially with the rod 10 along the specified third axis X3 and together with the specified third axis forms the first gap 12, illustrated specifically in FIG. 2 and 6. As, in particular, illustrated in FIG. 5, the screw drive And comprises at its first longitudinal end Pa, grooves 13 allowing the screw drive 11 to be attached to the gear (not illustrated) engaged with the worm gear (not illustrated) driven by the engine (not illustrated) so as to bring a screwing device 11 in rotation along the third axis X3. Preferably, the direction of rotation of the engine is reversible, which allows you to change the direction of rotation of the wrapper 11 to the opposite. The engine, gear and worm gear, known to those skilled in the art, are not illustrated for a better understanding of the drawings. Other gearing means may be provided between the engine and the spinner 11, also understood by one of ordinary skill in the art.

As illustrated in FIG. 2, 5 and 6, the wrapper 11 has a conical shape, elongated with expansion along the third axis X3 in the direction of the free end 10b of the rod 10. The wrapper 11 contains a recess 14, or a cutout elongated on its surface of revolution and extending to the free edge 15 on the second the longitudinal end lib of said wrapper 11. Said recess 14 preferably has a trapezoidal shape with a small base 14a illustrated by dashed lines in FIG. 5 and located at the level of the free edge 15. However, another shape of the recess 14 may be provided, for example, a more or less cylindrical shape or an oval shape. Similarly, the wrapper 11 may have a cylindrical surface of revolution. Most preferred are the conical surface of rotation and the trapezoidal recess 14, which ensure that the strands are wound properly along the coiler 11. At both ends 14b, 14c of the recess 14 intersecting the free edge 15, two hooks 16a, 16b are opposite each other on the protruding part of the indicated free edge 15. preferably with a slight outward shift relative to said free edge 15, as illustrated in FIG. 5. The two indicated hooks 16a, 16b are separated from each other by a gap, the width of which more or less corresponds to the width of the slot 7. In the initial position of the wrapper 11 at the beginning of curling, the recess 14 and two hooks 16a, 16b are located symmetrically relative to the plane P on the protruding part of the slot 7 as illustrated in FIG. 3, which allows you to insert into the specified recess 14 a portion of the strand located near the roots of the hair. The rotation of the curler 11 makes it possible to grab the strand with one of the two hooks 16a, 16b depending on the direction of rotation of the engine, so that it starts winding, as described below. The rotation of the curler 11 in two directions around the third axis X3 enables the formation of curls in two directions. However, one curling direction can be provided, in which case it is sufficient to have only one hook, and the configuration of the recess 14 can be changed. In the initial position, the angle of inclination α between the two axes X1 and X3, as described above, allows the recess 14 and two hooks 16a, 16b to be located near the free edge 10b of the rod 10 and the slot 7, with an inclination relative to the control handle 3. This facilitates the insertion of the strand into the slot 7 by placing it with an inclination relative to the wrapper 11, so as to insert it into the recess 14 during normal control of the control handle 3.

As illustrated in FIG. 2 and 6, the device 1 comprises an inner casing 17 located in the wrap chamber 12. Preferably, said inner casing 17 comprises a portion 18 having a cylindrical shape of a body of revolution about a third axis X3 and coaxially located around a wrapper 11 along a third axis X3 with a second gap 19 relative to said wrapper 11. Thus, the first gap 12 between the rod 10 and the wrapper 11 forms the inner chamber, and the second gap 19 between the wrapper 11 and part 18 of the inner casing 17 forms an outer chamber. In addition, the inner casing 17 contains two ridge protrusions 20a, 20b extending into the wrap chamber 8 parallel to the plane P and symmetrically with respect to the indicated plane P, while the corresponding upper edges 21a, 21b of these ridge protrusions 20a, 20b are adapted to adjoin the slot 7, which ensures the optimal direction of the strand to the wrapper 11, while the specified strand is held in the winding chamber 12 inside the second gap 19 of the inner casing 17. The specified inner casing 17 also provides be component placement device 1 in the housing 2 and thus avoids any risk of contact of the strand with said components during placement of said strands in a winding chamber 8.

As illustrated in FIG. 1-4, the slot 7 contains two walls 22a, 22b, located opposite each other symmetrically relative to the plane P in the thickness of the housing 2. These walls 22a, 22b are elongated along the entire length of the housing 2 and form between them in the plane P1 of a cut perpendicular to the plane P , V-shaped element, allowing the insertion of the strands into the specified slot 7. In sections 23a, 23b located on the side 2a of the housing 2, opposite the side 2b of the specified housing 2 having an outlet 9 and in contact with the hair roots during curling anija walls 22a, 22b are interconnected and form a V-shaped one-piece member with a rounded bottom 24, allows to guide the strand of hair with the possibility of drawing in the direction of length of the housing 2, i.e. in the direction of the second axis X2. The indicated sections 23a, 23b are located in front of the rod 10 and the wringer 11 in the direction of movement of the strand when it is wound. Preferably, the two walls 22a, 22b are integrally separate from the body 2, which allows the slot 7 to be made in a color different from the color of the body 2, so that it is easier to see when inserting a strand of hair. In addition, removable fastening means are arranged between the housing 2 and the walls 22a, 22b to enable the removal of said walls 22a, 22b, for example, to replace with other walls having a V-shaped element with a different angle at the base or other characteristics of the direction of the strand in the slot 7 These removable fasteners (not illustrated) may provide, for example, screwing or snapping the walls 22a, 22b onto the housing 2.

As illustrated in FIG. 1-4, transverse ribs 25, 26 are formed on two walls 22a, 22b, respectively, each of these transverse ribs 25, 26 having the shape of a disk part. In FIG. 1-4 it is shown that the wall 22b contains eight transverse ribs 26, having the form of a part of a disk with different sizes and gaps between them. The same applies to the transverse ribs 25 on the other wall 22a. These transverse ribs 25, 26 provide linear contacts with the hair strand, which reduces the friction of the strand in the slot 7 during its insertion. The shape of these transverse ribs 25, 26 in the form of a part of the disk also provides the formation of a more or less expanding V-shaped element between the transverse ribs 25, 26 located opposite each other on both walls 22a, 22b of the slot 7, which also contributes to the placement of the strand in the slot 7 The specified disk-shaped shape of the transverse ribs 25, 26 can be replaced by a triangular shape, which will also ensure the formation of a V-shaped element between the transverse ribs 25, 26, located opposite each other on the walls 22a, 22b.

As illustrated in FIG. 1-3, 6 and 7, the device 1 comprises a fixed foot 27, or a fixed foot, which is a rigid part, attached at the level of the contour 9a of the outlet 9. This fixed foot 27 has several functions. First of all, the fixed foot 27 provides the ability to block the rotation of the strand during its winding, so as to avoid turning the strand around the rod 10. In addition, this fixed foot 27 allows you to remove the curled lock without damaging it. The fixed foot 27 is perpendicular to the shaft 10, that is, perpendicular to the third axis X3, as illustrated in FIG. 2 and 7. Therefore, the inclination of the fixed foot 27 depends on the inclination at an angle α. When winding the strand around the rod 10, the strand is blocked by one of the two lateral blocking sides 28a, 28b of the fixed foot 27, depending on the direction of rotation of the wringer 11. The two indicated lateral blocking sides 28a, 28b are located symmetrically with respect to the plane P. To ensure that during winding the hair could not easily go beyond the fixed paw 27, it is necessary that the angle β formed between the side blocking side 28a and the straight line dl passing from the center 29 of the rod 10 to the base 30 of the side block side 28a, as illustrated in FIG. 8, ranged from 0 ° to 35 °. Preferably, said angle β is 25 °. The same applies to the second side blocking side 28b symmetrically to the first side blocking side 28a relative to the plane P. Thus, the hair strand tends to slip to the base 30 of the fixed foot 27 rather than its end 27a.

The fixed foot 27 should sufficiently overlap the free end 10b of the rod 10, while the distance from the fixed foot 27 to the rod 10 should be the smallest, so as to ensure that there is no likelihood of a lock of hair extending beyond the fixed foot and turning this lock around the rod 10 during winding . The fixed foot 27 extends from the cylindrical contour of the rod 10 to a height h1 in the range of 6 mm to 18 mm, preferably a height h1 of 12 mm, so as to provide the indicated sufficient overlap. At a higher height h1, difficulties may arise when removing the strand; at a lower height h1, there is a risk of insufficient lock of the strand. As for the distance to the rod 10, the fixed tab 27 is removed from the free end 10b of the rod 10 by a distance e1 ranging from 1 mm to 5 mm, preferably said distance e1 is 3 mm. The indicated distance e1 depends on the height h1 of the fixed foot 27. Preferably, the ratio r between the height h1 and the distance e1 is four (r = h1 / e1 = 4), the indicated ratio r can range from two to five (2 <r <5) .

In this configuration of the fixed foot 27 relative to the shaft 10, said shaft 10 has a diameter D ranging from 20 mm to 25 mm, preferably 22 mm.

The fixed foot 27 comprises an inner side 31 opposite the free end 10b of the shaft 10. The inner side 31 is curved or concave, as illustrated in FIG. 3 and 8, so as to ensure the maintenance of the curled locks of hair when removing it. The lower end 31a of the indicated inner side 31 is located under the shaft 10 with a maximum distance from it, so that when removing the hair does not go beyond the specified fixed foot 27, which would lead to their blocking. Said lower end 31a should also not have a too pronounced tip, it should have a rounded shape, so as to ensure the proper direction of the curled strand to the inner side 31, and not to the lower part of the fixed foot 27. In the illustrated in FIG. 9 of the embodiment, the fixed foot 27 comprises a curved inner side 31 with a lower end 31a elongated in the form of a curved beak 32, made continuously integrally with said inner side 31 so as to bias the lower end 31a towards the inner side 11 of the wraparound 11 illustrated in FIG. 5 and 6.

Preferably, the fixed foot 27 is removably secured against or near the contour 9a of the outlet opening 9. To this end, the fixed foot 27 comprises a lower part 33 in which a hole 34 is made, which makes it possible to fasten the fixed foot opposite the front side 2b of the housing 2 by means of a screw 35, as shown in FIG. 2, 7 and 8. Other removable fasteners may also be provided, not exceeding the scope of the legal protection of the invention. Said removable mount allows replacing the fixed foot 27 so that it is possible to select the foot most suitable for the type of curled hair, or when the foot is worn, to minimize friction of the curled lock during removal.

As illustrated in FIG. 2, the device 1 comprises a heating element 36 located inside the shaft 10 and configured to heat it and heat the hair strand. Such a heating element 36 is known to the person skilled in the art, therefore, it will not be described in detail. Other heating means may also be provided, located in the wrap chamber 8, for example, on the inner casing 17, and configured to heat the strands in the second gap 19 between the specified inner casing 17 and the wrapper 11.

The control of the housing 2 of the device 1 is carried out using the control handle 3, while its side 2a containing the outlet 9, when curling is placed at the roots of the hair. The installation of the handle 3 on the protruding part of the slot 7 provides easier control of the device 1. At the beginning of curling after the user adjusts the temperature of the heating element 36 to a predetermined temperature, the strand is placed inside the slot 7, then it is guided along the ridge protrusions 20a, 20b into the second gap 19 Due to the inclination of the screw-up device 11 and the rod 10 relative to the control handle 3, the insertion of the lock into the recess 14 is performed naturally without the need to tilt the lock from the housing 2 and Nuts 7 to ensure proper insertion into the recess 14. Then, using one of the control buttons 5 or 6, rotate the curler 11, which allows one of the hooks 16a, 16b, depending on the direction of rotation, to grab or hook the strand near the hair roots. The advantage of the configuration of the curler 11, in which it has a recess 14 and its rotation surfaces are located around the rod, is the possibility of simultaneously winding strands of hair around the rod 10 in the inner chamber formed by the first gap 12, and the circumference of the surface of rotation of the wrapper 11 in the outer chamber formed by the second gap 19. When winding simultaneously on the wrapper 11 and the rod 10, the lock is pulled to the base 24 of the slot wall 22a, 22b 7. After pulling the tip of the strand to the base 24 and wound around the wrapper 11 the rotation of the specified winder continues, which allows the wrapper to continue winding the specified strand around the specified rod 10 until then, until the whole strand is wound around the specified rod 10. Then, the rotation of the wrapper 11 is stopped, while the heating element 36 remains on, and the strand is kept wrapped around the rod 10 for several seconds. Then the device 1 is removed from the hair roots, while the curled strand moves along the rod 10 to the fixed foot 27, which, when the device is removed from the head, will support the curl when bringing the strand to the outlet 9, so as to ensure proper removal of the curled strand.
