Description

  The present invention relates to the field of hair styling devices for curling hair tresses, and in particular to hair styling devices with an automated tress winding device for curling tresses.

  Such hair styling devices for curling hair tresses with automated tress winding devices for curling the tresses are already known to those skilled in the art. For example, published patent applications describe such hair styling devices (see, for example, Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4, and Patent Document 5). According to this type of design, the hair styling device is adapted to wind the hair tress around the mandrel with a housing having a winding chamber with an opening for inserting the hair tress, a mandrel arranged in the wrapping chamber, and And a wrapping machine configured as described above.

  In U.S. Patent No. 6,057,051, the wrapping machine is shaped like a spiral with teeth so that when the device is turned on, the hair strands are gripped and wrapped around a heated mandrel.

  In Patent Document 2, the winding machine is in the form of a cylinder arranged coaxially around a portion of the mandrel in the winding chamber of the housing. The mandrel has a conical head that extends outside the winding machine and the winding chamber of the housing. The wrapping machine has an incision with hooks that allow the styling to be wrapped around the wrapping machine and around the conical head of the mandrel while moving the hair styling device relative to the scalp.

  The aforementioned hair curl devices described in Patent Document 1 and Patent Document 2 are complicated to use and are not ergonomic. Also, they do not allow effective hair curling because the wrapped hair is not kept near the mandrel for proper curl formation.

  In U.S. Patent No. 6,057,033, the housing of the hair styling device has a slot disposed along the length of the winding chamber, and the hair tress penetrates the slot for winding around the mandrel. The lateral guide blades are arranged in a V-shape longitudinally outside the slot for receiving tufts. The winding machine is in the form of a disc that is placed around a mandrel. The disc is larger than the housing, so it passes through the slot and the guide blade. The disc has a radial cut that connects to its surrounding outline to form a hook so that the cut penetrates the slot to facilitate positioning the hair lock with the cut to grasp the lock. Can be positioned between the guide blades. Once the tuft is in place at the incision, it is wrapped around the mandrel from the scalp to the end of the tuft in the winding chamber. This wrapping machine design requires the gripped tress to be wrapped around both sides of the disc, which can cause the hair to pull through the wrapping and thus risk damaging the hair. Also, this winding on both sides of the disk can easily clog the tuft in the casing's winding chamber. This design is also very bulky.

  In Patent Document 4, the hair curl device is in the form of a clamp formed from two arms. The housing is disposed at one end of the two arms, and has an insertion slot extending longitudinally in the housing in the direction of the winding chamber, and the slot communicates with the winding chamber. The housing has an external guiding element which is arranged outside the slot in the shape of a V and allows the hair strands to be guided for insertion into the slot in the wrapping chamber. Compared with the hair styling instrument described in US Pat. No. 6,057,049, the wrapping machine is in the form of a disc that is shaped like a hook that passes through the slot in order to be positioned between the guide elements. The second arm has, at its distal end, a second housing with a receiving area for the guiding element and a carrying surface, so that the carrying surface guides the hair tress while being guided by the guiding element. Can be pushed in, so that the wrapping machine can grip the tuft to wrap it around the mandrel. This design is also very bulky. Also, the design is complex, which complicates its production and increases its manufacturing costs.

  In Patent Document 5, in relation to Patent Document 4, the housing defines a winding chamber in which a mandrel with one end fixed to the housing and a free end adjacent to the extraction opening to which the winding chamber is connected extends. The wrapping machine is also in the form of a disc with cuts that form hooks that allow the tuft to be gripped to wrap the tuft around the mandrel. In the first implementation, the housing has a large insertion opening to position the tuft in the winding chamber. In a second variant, the housing has an insertion slot that extends longitudinally and communicates with the winding chamber, and above the mandrel, a V-shaped guide element facilitates positioning the tuft facing the slot. Therefore, it is arranged outside the slot. According to these different variants, the hair curling instrument comprises an insertion device configured to push the tress into the insertion opening or into the insertion slot and position it in a notch on the disc. This design is complex, implements a large number of parts, makes its production difficult, and increases its manufacturing costs. This design also makes it more bulky.

French Patent Application Publication No. 2373986 Specification German Patent Application Publication No. 2816289 International Publication No. 2009/0777747 International Publication No. 2012/080751 International Publication No. 2013/186547

  The main object of the present invention is to implement a hair styling device that remedies the aforementioned drawbacks of previous hair curl devices, while allowing the tress to be easily grasped for wrapping.

  Another object is to provide a hair curling device that is easy and practical to use while allowing effective treatment of the hair.

  Another object is to prevent the tufts from becoming clogged or tangled inside the wrapping housing and to make regular curls without damaging the hair.

  Another object of the present invention is to curl the hair strand substantially in its entire length without reducing the effectiveness of the hair styling device and without the risk of scalp burns.

  For these purposes, the present invention relates to a hair styling device for curling hair strands, also called a hair curling device. The hair tiling instrument includes a grip handle extending in the longitudinal direction along the first axis X1 and a housing attached to the grip handle. The grip handle can be in various aesthetic and ergonomic forms to allow proper gripping.

  The housing has a winding chamber having a shape defined by rotating along the second axis X2, and the first axis X1 and the second axis X2 define a plane P. The housing extends in the length of the housing in a plane P approximately parallel to the second axis X2 and also has an insertion slot leading to the winding chamber, through which the hair tress is inserted into the winding chamber. This slot is positioned in the housing on the opposite side of the grip handle location. The housing is also arranged on one of its two side surfaces and also has an extraction opening leading to the winding chamber.

  Significantly, the hair styling device is in a plane P passing through the second axis and slot with one end fixed to the housing and a free end located near the extraction opening in the winding chamber. A mandrel extending in the winding chamber along a defined third axis X3. Preferably, the slots are arranged symmetrically with respect to the plane P. Also, the third axis X3 is inclined with respect to the first axis X1 according to an angle α such that the free end of the mandrel is farther from the grip handle than the fixed end of the mandrel.

  Also, the hair styling device is disposed coaxially with the mandrel along the third axis X3 with a surface rotating along the third axis X3, with a first space around the mandrel in the winding chamber. A hollow wrapping machine. The winding machine is mounted rotatably in at least one direction along the third axis, preferably according to both directions of rotation. The winding machine has capture means configured to capture at its rotating surface a tuft at an initial position of the winding machine and then rotate the tuft during rotation of the winding machine. The wrapping machine also continuously grasps or captures the proximal end of the tuft, simultaneously wraps the tuft around the mandrel and the wrapping machine, and then rotates the tuft around the mandrel. Configured to wind completely between.

  This design of the hair styling device according to the invention advantageously allows the tuft to be inserted into the insertion slot while positioning it at an angle with respect to the mandrel and wrapping machine, and then the tuft to the slot The tuft is inserted into the capture means on the rotating surface of the wrapping machine without having to tilt. This means that while the user naturally holds the grip handle, the tress is inserted into the slot without any complexity with respect to its positioning, and then the end of the tress located close to the root is By holding the extraction opening against the scalp so that it is positioned in the capture means, the operation of the instrument is considerably facilitated.

  This design of the hair styling device according to the invention also makes the winding chamber into two concentric chambers, i.e. one inner chamber defined by a first space between the mandrel and the winding machine, and the winding chamber. It is allowed to divide into one outer chamber defined by the space outside the winder on the inside. This allows the hair tress to be wrapped around the mandrel and wrapping machine simultaneously. The wrapping machine surrounds the mandrel along its length and has a larger wrapping diameter than the mandrel, thereby allowing the hair to be wrapped around the mandrel with less tension. Therefore, there is almost no risk of hair damage. Also, the longitudinal shape of the mandrel and wrapping machine allows the hair tress to be wound with a relatively large surface area and prevents the hair from becoming clogged.

  In an embodiment of the hair styling device according to the invention, the angle α is between 50 and 80 degrees, preferably 70 degrees.

  In an embodiment of the hair styling 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 grip handle and the mandrel and wrapping machine are tilted in the winding chamber. In a variant embodiment of the hair styling device according to the invention, the second axis X2 and the third axis X3 are parallel to each other, preferably coincident. This arrangement maintains the mandrel and wrapping machine at the axis of the wrapping chamber of the housing while maintaining the advantage of facilitating positioning of the hair tress in the slot and wrapping device capture means, and tilting the housing relative to the handle Make it possible. Also, various modifications can be recalled without departing from the context of the present invention. In this regard, in a variant embodiment of the hair styling device according to the invention, the second axis X2 is on the same side as the third axis X3 and between 90 degrees of the inclination angle α of the third axis X3. At an angle φ (α <φ <90 °) with respect to the first axis X1.

  In an embodiment of the hair styling device according to the invention, the winding machine has a free edge which is arranged on the free end side of the mandrel. The winding machine also has an incision constituting the capture means that extends on the rotating surface of the winding machine and leads to a free edge, the incision winding the tuft with the mandrel at the initial position of the winding machine. It is comprised so that it can penetrate to the 1st space between machines. According to this embodiment, the gripping means is formed at at least one of the two ends of the incision intersecting the free edge, preferably at both ends. These gripping means are preferably in the form of hooks. A single hook can be recalled when the winder rotates in only one direction. Preferably, the winding machine rotates in both directions along the third axis X3 and the two hooks are arranged facing each other at the two aforementioned ends of the cut. Preferably, according to this embodiment, the cut has a trapezoidal shape with its small base adjacent to the free edge. However, deformations can be recalled in the form of cuts, for example circular or elliptical.

  In an embodiment of the hair styling device according to the invention, the winding machine has the shape of a cylinder along the third axis X3. In a variant of the preferred embodiment, the winding machine has a conical shape along the third axis X3, which exhibits an enlargement in the direction of the free end of the mandrel.

  In an embodiment of the hair styling device according to the invention, the insertion slot extends longitudinally in the direction of the second axis X2 and forms a V-shape therebetween that is configured to help the tuft penetrate the winding chamber. Has two walls. Thus, unlike the prior art, which provides additional elements that form a V-shape located outside the slot, the present invention provides for the incorporation of a V-shape directly into the thickness of the housing, which is hair styling. The overall size of the instrument is significantly reduced.

  Preferably, according to this embodiment, the slot has a longitudinal end portion opposite the position of the extraction opening, in which the two walls are connected to each other, and the entire V-shaped in a single piece. The V-shaped bottom is rounded and configured to guide the tuft and slide it during winding of the tuft around the mandrel and wrapping machine. This longitudinal part is arranged upstream from the mandrel and the wrapping machine in the housing. This design also helps reduce tufting in the tuft during winding of the tuft around the mandrel and wrapping machine. According to a variant, the slot has a longitudinal end portion opposite to the position of the extraction opening, in which the two walls are connected to each other, guide the tuft, around the mandrel and the winder Form a curved bottom, roughly in the shape of a spoon, that is configured to allow it to slide during wrapping of the tuft. This longitudinal part is arranged upstream from the mandrel and the wrapping machine in the housing.

  In an embodiment of the hair styling device according to the invention, the insertion slot extends longitudinally in the direction of the second axis and has two walls each having an auxiliary material arranged transversely to the second axis X2. Have These aids are distributed along each wall and are configured to help the tuft pass through the winding chamber. These aids provide linear contact between the slot and the hair tress during the latter insertion to reduce friction and limit the risk that the tress will become clogged with the slot. It has the advantage that it can be performed. Preferably, according to this embodiment, the aids are each in the form of a part of a disc, which gradually increases the passage cross section of the slot, such as a V-shape disposed between the two walls. The tuft can be guided during its insertion in the slot. Shape variations for these aids can be recalled, while also helping to reduce the cross-section of the slots, such as triangles. Preferably, according to this embodiment, the aid is of variable dimensions on each wall due to the variable distribution on each wall.

  In an embodiment of the hair styling device according to the invention, the insertion slot has two walls, each extending longitudinally in the direction of the second axis X2 and each presenting an undulating portion along the wall. These undulations are configured to help the tuft penetrate the wrapping chamber. These undulations have the advantage of reducing contact between the slot and the hair tress during the latter insertion, which reduces friction and limits the risk that the tress will become clogged with the slot To do.

  In another embodiment, the slot has three previous embodiments, in particular the presence of two walls forming a V-shape and / or the presence of undulations in the two walls and / or these two Combine at least two characteristics of the presence of auxiliary material in the wall. The characteristics of these deformations each constitute a guiding means arranged in the slot and configured to help the tuft penetrate the winding chamber. Of course, other variations of the guiding means can be conceived without departing from the context of the present invention.

  In an embodiment of the hair styling device according to the invention, the latter comprises a stationary finger arranged in the outline of the extraction opening or a stationary finger arranged in close proximity to this outline and in front of the free end of the mandrel. . The shape of the immovable fingers prevents curling around the mandrel and prevents curling at the end of the curling action without the risk of circumventing the fingers during the winding machine rotation. Configured to the free end of the mandrel to assist in releasing the constrained tuft along the mandrel. The presence of such a stationary finger is, for example, actuating means for being placed in an actuating position for fixing the tuft in the outline of the extraction opening or, conversely, in a releasing position for allowing the curled tuft to be opened. Unlike existing systems from the prior art that are much more complex, such as the instrument described in US Pat. To make it possible.

  Preferably, the immovable finger portion is perpendicular to the third axis and parallel to the plane P. Further, the non-moving finger portion has a straight line d1 passing through the base portion of the side fixing surface and perpendicularly cutting the third axis, and the side fixing surface is between 0 and 35 degrees, preferably 25 degrees. Having at least one lateral fixation surface configured to form an angle β. This advantageously allows the hair tress to be slid toward the base rather than towards the end of the stationary finger, which prevents the finger from being bypassed during wrapping.

  Preferably, the stationary finger portion is perpendicular to the third axis X3 and parallel to the plane P. In addition, the finger portion is configured to extend from the peripheral outer shape of the free end of the mandrel at a height h1 between 6 mm and 18 mm, preferably 12 mm, in the direction of the third axis. This also helps to prevent the tuft from bypassing the immobile fingers during tuft wrapping without compromising the release of the curled tuft.

  Preferably, the immovable finger portion is perpendicular to the third axis and parallel to the plane P. Also, the finger is spaced from the free end of the mandrel by a distance e1 between 1 mm and 5 mm, preferably 3 mm. This includes securing the tuft during wrapping around its mandrel without the risk of bypassing the stationary finger and properly releasing the curled tuft without risk of loosening it. It also allows for a convenient compromise between the two.

  Preferably, the mandrel has a diameter D of between 20 mm and 25 mm, preferably 22 mm, due to the stationary finger exhibiting the aforementioned characteristics.

  Preferably, the immovable finger portion has an inner surface arranged facing the free end of the mandrel. This inner surface has a curved shape configured to support the release of the curled hair tress through the extraction opening. The inner surface is adjacent to the contour of the extraction opening extending in the form of a nozzle that is more or less prominent to prevent the curled tuft from passing under the stationary finger and remaining fixed during release Has a lower end.

  Preferably, according to this embodiment of the hair styling device, the removable fixing means are arranged between the stationary finger and the contour of the extraction opening. This advantageously makes it possible, for example, to replace the finger with another that exhibits some form of deformation in order to better adapt the hair styling device to the type of hair to be curled.

  According to the hair styling device according to the invention, the latter comprises heating means configured to heat the hair tress inside the winding chamber. Preferably, the heating means is arranged on the mandrel. However, it is possible to recall a heating means arranged in the winding chamber in order to heat the tuft around the mandrel and the winder during its simultaneous winding.

  In an embodiment of the hair styling device according to the invention, the housing additionally has an inner cage arranged in a winding chamber around the winding machine, with a second space for the winding machine. The inner cage is configured to lengthen the guide of the hair tress in the direction of the wrapping machine inside the wrapping chamber after it passes through the slot. This also makes it possible to restrict the tuft around the winder inside the housing without the risk of dispersion in the winding chamber.

  In the remainder of this specification, the same reference numerals will be used to describe similar properties according to various embodiments.

  In the remainder of this description, the term “apparatus” will be used to indicate a hair curl apparatus according to the present invention unless otherwise indicated.

  In FIG. 1, the instrument 1 includes a housing 2 and a grip handle 3. The appliance 1 is electrically connected to the power supply by means of an electric cable 4 and controls buttons 5, 6 which allow to activate the heating means and means for rotating the winding machine which will be described in more detail later. Is provided.

  As shown in FIGS. 2 to 4, the grip handle 3 extends in the longitudinal direction along the first axis X1.

  As shown in FIGS. 1 to 4, the housing 2 has a slot 7 into which a hair tress (not shown) can be inserted into a winding chamber 8 defined inside the housing 2. In chamber 8, the curl of the tuft is performed. The housing 2 also has an extraction opening 9 on its front side 2b through which the tuft is opened or removed after it has been curled. The winding chamber 8 has an approximately cylindrical shape that is defined by rotating along a 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 a plane P shown in FIGS. 1 to 3, and form a symmetrical plane of the housing 2 and the grip handle 3. ing. The slot 7 is positioned in this plane P in the housing 2 on the side opposite to the position of the grip handle 3.

  As shown in FIGS. 1 to 3 and 6, the instrument 1 comprises a mandrel 10 having a fixed end 10 a incorporated in a housing 2. The mandrel 10 also has a free end 10 b that is positioned in the winding chamber 8 in proximity to the extraction opening 9. The mandrel 10 extends longitudinally inside the winding chamber 8 along a third axis X3 which defines an angle α of inclination between the first axis X1 and between 50 ° and 80 °. Preferably, the inclination angle α is 70 °. This inclination of the mandrel 10 advantageously allows its free end 10b to be positioned further away from the end 3a of the grip handle 3 than its fixed end 10a, as will be explained later. In addition, it is easy to position the tuft to wind the tuft. The third axis X3 is defined in the plane P shown in FIGS. The slots 7 are arranged symmetrically with respect to this plane P, in particular as shown by FIGS.

  As shown in FIGS. 1 to 3, 5, and 6, the instrument 1 includes a winding machine 11 that is hollow and has a shape rotated along a third axis X <b> 3. The winding machine 11 is positioned coaxially with the mandrel 10 along the third axis X3, and together with the latter, defines the first space 12 shown in FIGS. 2 and 6 in particular. In particular, as shown in FIG. 5, the winding machine 11 is rotated at its first longitudinal end 11a by a motor (not shown) to rotate the winding machine 11 along the third axis X3. The spline 13 is arranged so that the winding machine 11 can be fastened to a gear (not shown) that meshes with a worm screw (not shown) that can be moved. Preferably, the direction of rotation of the motor is reversible, which makes it possible to reverse the direction of rotation of the winding machine 11. Motors, gears, and worm screws are not shown for ease of reading the figure, the latter being further within the understanding of those skilled in the art. Other meshing means may also be conceived between the motor and the wrapping machine 11 within the scope of understanding of those skilled in the art.

  As shown in particular in connection with FIGS. 2, 5 and 6, the winding machine 11 has a conical shape extending in the direction along the third axis X3 in the direction of the free end 10b of the mandrel 10. Have The winding machine 11 has a notch 14 or a cut, which extends at its rotated surface and is connected to the free edge 15 at the second longitudinal end 11b of the winder 11. This incision 14 preferably has a trapezoidal shape with its small base 14a, shown in dotted lines in FIG. However, other shapes may be recalled for this notch 14, for example approximately cylindrical or elliptical. Similarly, the winding machine 11 can have a rotating cylindrical surface. A rotating conical surface and a trapezoidal cut 14 are preferred, which favors better wrapping of the tuft along the wrapping machine 11. At the two ends 14b, 14c of the incision 14 intersecting the free edge 15, two hooks 16a, 16b are arranged in line with the free edge 15 and preferably facing each other, preferably as shown in FIG. Furthermore, it is slightly shifted outward with respect to the latter. These two hooks 16a, 16b are spaced apart by a width approximately corresponding to the width of the slot 7. At the beginning of the curling operation at the initial position of the winding machine 11, the incision 14 and the two hooks 16a, 16b are aligned with the slot 7 and symmetrically with respect to the plane P, as shown in FIG. This makes it possible to insert into this slot 14 the part of the tress that is located close to the scalp. Then, by rotating the winding machine 11, one of the two hooks 16a, 16b can be started to grip the tuft and start winding it according to the direction of rotation of the motor, which will be described later. . The rotation of the winding machine 11 in both directions around the third axis X3 makes it possible to make a curl in both directions. However, a single direction curl can also be considered, in which case a single hook is sufficient and the configuration of the incision 14 can be adapted. In the initial position, the angle of inclination α between the two axes X1 and X3 as described above causes the notch 14 and the two hooks 16a, 16b to be close to the slot 7 near the free edge 10b of the mandrel 10. Thus, it is advantageously possible to position it so as to be inclined with respect to the grip handle 3. This facilitates the insertion of the tuft in the slot 7 by positioning it at an angle relative to the winder 11 for its insertion at the incision 14 while operating the grip handle 3 normally.

  As shown in FIGS. 2 and 6, the instrument 1 includes an inner cage 17 disposed in the winding chamber 12. Preferably, the inner cage 17 has a cylindrical shape rotating about the third axis X3 and arranged coaxially around the winding machine 11 along the third axis X3. It has a portion 18 with two spaces 19. Accordingly, the first space 12 between the mandrel 10 and the winding machine 11 defines an inner chamber, and the second space 19 between the winding machine 11 and a portion 18 of the inner cage 17 defines an outer chamber. Yes. The inner cage 17 further has two flanges 20a, 20b extending symmetrically with respect to the plane P in the winding chamber 8 in parallel with the plane P, and the upper edge 21a of each of these flanges 20a, 20b. , 21b are configured to be positioned proximate to the slot 7, which restricts the tuft to the inside of the second space 19 of the inner cage 17 in the winding chamber 12, thereby Allows better guidance. This inner cage 17 also allows the components of the instrument 1 to be placed in the housing 2 while avoiding contact between the tufts and these components during tuft positioning in the wrapping chamber 8. To do.

  As shown in FIGS. 1 to 4, the slot 7 has two walls 22 a and 22 b, which are arranged symmetrically with respect to the plane P and facing each other in the thickness of the housing 2. The These walls 22 a and 22 b extend in the entire length of the housing 2, and form a V shape that assists insertion of the tuft in the slot 7 in a cross section P 1 perpendicular to the plane P. In their part 23a, 23b, which is located on the side 2a of the housing 2 opposite to the side 2b of the housing 2 which has an extraction opening 9 and will come into contact with the scalp during curling, the walls 22a, 22b is a rounded bottom 24 which is connected and guides the hair tress by sliding it along the length of the housing 2, i.e. in the direction of the second axis X2, and is V-shaped by a single item. The whole is formed together. These portions 23a, 23b are positioned upstream from the mandrel 10 and the winder 11 according to the direction of movement of the tufts while the tufts are wound. Preferably, these two walls 22a, 22b consist of a single piece independent of the housing 2, which makes it possible to make the slot 7 in a color different from the color of the housing 2, so that it is a hair tress Can be seen more easily during insertion. Removable fixing means are also arranged between the housing 2 and the walls 22a, 22b, eg, other with different V-shaped angles or other characteristics that guide the tuft in the slot 7 They can be removed to replace things. These removable fixing means (not shown) can consist, for example, of screwing or snapping the walls 22a, 22b in the housing 2.

  As shown in FIGS. 1 to 4, crossing aids 25 and 26 are respectively implemented in two walls 22 a and 22 b, and these crossing aids 25 and 26 each form a part of a disc. Have. In FIGS. 1 to 4 it can be seen that the wall 22b has eight crossing aids 26 in the form of part of a disc, which have different dimensions and are spaced apart. The same applies to the crossing aid 25 on the other wall 22a. These crossing aids 25, 26 allow for linear contact with the hair tress, which reduces tress friction in the slot 7 during its insertion. The fact that these crossing aids 25, 26 have the form of part of a disc is due to the fact that a V-shape is formed between the crossing aids 25, 26 arranged facing each other in the two walls 22 a, 22 b of the slot 7. It is also possible to have a broad shape that roughly forms, which also favors the positioning of the tufts in the slot 7. This disc shape of the crossing aids 25, 26 may be replaced by a triangular shape, which is a V-shape between the crossing aids 25, 26 arranged facing each other on the walls 22a, 22b. It is also possible to form.

  As shown in FIGS. 1 to 3, 6, and 7, the instrument 1 includes a stationary finger portion 27 or a fixed finger portion made of a rigid portion that is attached to the outer shape 9 a of the extraction opening 9. . This immovable finger portion 27 has several functions. First, the immovable finger 27 makes it possible to prevent the tuft from rotating during tuft wrapping in order to prevent the tuft from turning around the mandrel 10. Also, this immovable finger 27 must ensure the release of the curled tuft without damaging it. The immovable finger 27 is perpendicular to the mandrel 10, that is, perpendicular to the third axis X3, particularly as shown in FIGS. Therefore, the inclination of the fixed finger portion 27 depends on the inclination of the angle α. During winding of the tuft around the mandrel 10, the tuft is fixed by one of the two lateral fixing surfaces 28 a, 28 b of the stationary finger 27 according to the direction of rotation of the winding machine 11. These two side fixing surfaces 28a and 28b are arranged symmetrically with respect to the plane P. In order to prevent the hair from circumventing the immobile finger 27 during wrapping, from the side fixing surface 28a and from the center 29 of the mandrel 10 to the base 30 of the side fixing surface 28a as shown in FIG. The angle β formed between the straight line d1 and the straight line d1 should ideally form an angle between 0 ° and 35 °. Preferably, this angle β is 25 °. The same applies to the second side fixing surface 28b arranged symmetrically with respect to the first side fixing surface 28a according to the plane P. In this method, the hair tress tends to slide toward the base 30 of the stationary finger portion 27 rather than toward the end 27 a of the stationary finger portion 27.

  Also, in order to better ensure that the hair tress does not tend to turn around the mandrel 10 around the immobile finger during wrapping, the immobile finger 27 is free end 10b of the mandrel 10. Must be sufficiently covered and its distance from the mandrel 10 should be as small as possible. In order to be able to cover this sufficiently, the immobile finger 27 extends from the cylindrical contour of the mandrel 10 with a height h1 between 6 mm and 18 mm, preferably with a height h1 equal to 12 mm. Larger heights h1 risk penalizing release, while smaller heights h1 risk not fixing the hair sufficiently. Considering the distance to the mandrel 10, the stationary finger 27 is spaced from the free end 10b of the mandrel 10 by a distance e1 between 1 mm and 5 mm, which distance e1 is preferably equal to 3 mm. This distance e1 depends on the height h1 used for the fixed finger portion 27. Preferably, a ratio r of 4 is provided between the height h1 and the distance e1 (r = h1 / e1 = 4), this ratio r being between 2 and 5 (2 <r <5).

  For this aforementioned configuration of the stationary finger 27 with respect to the mandrel 10, the mandrel 10 has a diameter D between 20 mm and 25 mm, preferably 22 mm.

  The immovable finger portion 27 has an inner surface 31 that is arranged facing the free end 10 b of the mandrel 10. The inner surface 31 is curved or recessed, particularly as shown in FIGS. 3 and 8, which makes it possible to support drainage during its release of the curled hair strand. The lower end 31a of the inner surface 31 must be as far as possible under the mandrel 10, so that during release, the hair will not pass under this stationary finger 27 and thus will not fix the hair. This lower end 31a should not be formed with a sharp pointed end, in order to properly orient the curled tuft on the inner surface 31 so that it is not below the stationary finger 27, and is rounded. Must have a different form. In the variant embodiment shown in FIG. 9, the immovable finger 27 has a curved inner surface 31 with its lower end 31a extending in the form of a curved nozzle 32 arranged in line with the inner surface 31. Is particularly advantageous for moving the lower end 31a towards the inner surface 11c of the winding machine 11c shown in FIGS.

  Preferably, the immovable finger portion 27 is detachably fixed to the outer shape 9a of the extraction opening 9 or close to the latter. To achieve this, the immovable finger 27 is provided with an opening 34 that allows screwing 35 against the front side 2b of the housing 2, as illustrated by FIGS. Has a lower portion 33 provided. Other removable securing means can be envisaged without departing from the context of the present invention. This removable fixation is used to better match the immobile finger 27 to the type of hair to be curled, or when the curled tuft is opened, when the finger is worn, the friction of the curled tuft. In order to suppress as much as possible, it is advantageously possible to replace the stationary finger 27.

  As shown in FIG. 2, the appliance 1 comprises a heating element 36 arranged inside the mandrel 10 for heating the mandrel 10 and for heating the hair tress. Such heating elements 36 are known to those skilled in the art and are therefore not described. For example, other heating means arranged in the winding chamber 8, such as in the inner cage 17, can be conceived for heating the hair in the second space 19 between the inner cage 17 and the winding machine 11.

  The housing 2 of the instrument 1 is manipulated by a grip handle 3, the side 2a of which has an extraction opening 9 and is positioned against the scalp during various curling actions. The arrangement of the grip handle 3 in line with the slot 7 facilitates the operation of the instrument 1. At the beginning of the curling operation, after the user sets the heating element 36 to a set temperature, the tuft is positioned inside the slot 7 and then guided to the second space 19 by the flanges 20a, 20b. Since the wrapping machine 11 and mandrel 10 are tilted with respect to the grip handle 3, the insertion of the tuft at the incision 14 will cause the tuft to be relative to the housing 2 and the slot 7 in order to properly insert the tuft into the cut 14. Naturally without the need to tilt. Next, rotation of the winding machine 11 is triggered by one of the control buttons 5 or 6, depending on the direction of rotation, either on one of the hooks 16a, 16b, grabbing the tuft close to the scalp or Can be captured. The configuration of the winding machine 11 in which the surface of rotation is arranged around the mandrel and its notch 14 is arranged around the mandrel 10 in the inner chamber defined by the first space 12 and in the second space 19. Advantageously enables simultaneous wrapping of the hair tress around the surface of rotation of the wrapping machine 11 in the outer chamber defined by. During this simultaneous winding on the winding machine 11 and mandrel 10, the tuft slides to the bottom 24 of the walls 22a, 22b of the slot 7. As the end of the tuft slides to the bottom 24 and wraps around the wrapping machine 11, the wrapping machine continues to rotate, which continues to wrap the tuft around the mandrel 10 until the entire tuft is wrapped around the mandrel 10. Make it possible. The winder 11 then stops turning and the heating element 36 remains activated while keeping the tuft wrapped around the mandrel 10 for several seconds. The instrument 1 is then moved away from the scalp, so that the curled tufts are removed in order to properly release the curled tufts as the instrument is moved away from the head. It is displaced along the mandrel 10 toward the stationary finger portion 27 that will be accompanied by the curl. Variations of the guiding means may be conceived in the context of the present invention. Specifically, an embodiment of a variant of the slot 7 with only the walls 22a, 22b in a V shape without the crossing aids 25, 26 can be considered, or conversely, the shape of the crossing aid is triangular or It is possible to envisage crossing aids 25, 26 in walls parallel to each other, which in the form of a part of a disc define a widened or V-shaped shape by itself. As shown in FIGS. 1 and 2, it is also possible to consider undulations 37, 38 arranged between the crossing aids 25, 26 over the length of the two walls 22a, 22b. It also helps to reduce hair tress friction on the walls 22a, 22b. These wavy portions 37, 38 in the two walls 22a, 22b forming the V-shape can also be considered without the presence of the crossing aids 25, 26.

  In the variant embodiment of the instrument 1 shown in FIGS. 10 and 11, the slot 7 has two walls 22a, 22b, which are inclined together in a V shape, the variant of FIGS. As described above with respect to this embodiment, the corrugated portions 37 and 38 are provided. Similarly, in FIG. 11, as described for the previous variant, the bottom 24, as can be seen in FIG. 11, is a portion 23 a, 23 b of two walls 22 a, 22 b that are a single piece with a common bottom 24. Is slightly rounded because it is unrounded and flat.

  In another embodiment of the variant of the instrument 1 shown in FIG. 12, the slot 7 has two walls 22a, 22b, which are inclined together in a V shape, as described above, 38. Also, the portions 23a, 23b of the two walls 22a, 22b consist of a single piece with a common bottom 24 that is curved or spoon-shaped, as can be seen from FIG. It is also possible to guide the tress in slot 7 during wrapping of the tress around the machine 11 and the mandrel 10.

  According to the two previous embodiments of deformation of the instrument 1, the design of deformation of the winding machine 11 and the stationary finger 27 as described above is also applied.

  Variations of the immovable finger 27 or even other securing means can be envisaged without departing from the main context of the present invention.

  Other embodiments of the instrument 1 may be considered without departing from the context of the present invention. In the aspect of the embodiment of FIGS. 1 to 4, the second axis X2 (in accordance with which the shape of rotation of the housing 2 is defined) is perpendicular to the first axis X1, ie the second axis Is inclined by an angle φ equal to 90 ° with respect to the axis X2. In the variant embodiment shown in FIGS. 10 and 11, the second axis X2 coincides with the mandrel 10 and the third axis X3 of the winding machine 11, that is, the second axis X2 is aligned with the first axis X1. With respect to the second axis X2, the first axis X1 corresponds to the inclination angle α of the third axis X3. A second axis X2 that is parallel to the third axis X3 but not coincident with the third axis X3 can also be considered. It is also possible to consider an inclination angle φ of the second axis X2 with respect to the first axis X1, which is between the inclination angle α of the third axis X3 and 90 °, ie α <φ <90 °. Thus, in the range of values of angle α between 50 ° and 80 °, as described above, when angle α is equal to 50 °, angle φ can be between 50 ° and 90 °, and angle α is 80 When equal to °, the angle φ can be between 80 ° and 90 °, and for a preferred value of the angle α equal to 70 °, the angle φ can be between 70 ° and 90 °.
