Description

STYLING DEVICE WITH ADJUSTABLE BLOWER ACCESSORY

Technical area

The present invention relates to the field of hairdressing appliances and in particular to the field of hairdressing appliances making it possible to produce curls and / or waves on the hair. The present invention relates in particular to the field of hairdressing appliances blowing hot air.

More specifically, the invention relates to the technical field of hairdressing devices comprising a main body comprising a handle extending longitudinally along a first axis, a device for setting the air in motion making it possible to create an air flow between an air inlet and an air outlet, an accessory intended to come into contact with the hair in order to shape the latter, said accessory extending longitudinally along a second axis, the main body comprising the air inlet at the level of a free end and the accessory comprising the air outlet.

This type of device is commonly referred to as a blower brush.

Prior art

Hairdressing devices making it possible to relax the hair and / or to give volume and waves to the hair are well known. These devices are generally equipped with a rotating accessory forming a mandrel on which the hair can be shaped or even rolled up. The mandrel is generally heated, which allows the shaping of the hair to be fixed. These devices can blow hot air, on the one hand to heat the accessory and on the other hand the hair, as is for example the case of the device described by the patent EP2131695 of the applicant, which forms a blower brush.

This type of device gives excellent results in terms of hair shaping and is therefore very popular with users. However, this type of device can sometimes present some difficulty in its use, especially when the device is used by a single person who is trying to style their own hair.

Indeed, when the user wishes to carry out the shaping of the hair located at the back of his head, he must perform a complex movement with his arm, forearm and wrist, to position the device correctly behind his head. The movement in question, then the holding of the device in position, can then prove to be delicate, non-intuitive and above all uncomfortable.

Indeed, in order to position the hairdressing device of the prior art correctly behind his head, the user must raise his arm at shoulder level, extend it to the side, while fully bending his elbow to bring back his forearm and his hand behind his head. Finally, the user usually needs to bend their wrist to orient the styling device in the correct position relative to their hair.

This sometimes results in a position of using known devices that is complex, uncomfortable, tiring or even painful or even sometimes impossible to perform for people with joint or muscle disorders. The physical effort required to use existing devices, especially on the back of the head, can therefore be significant or even painful.

There is therefore a need to improve existing devices, in particular in terms of their ergonomics and comfort of use.

Disclosure of the invention

The object of the present invention is to overcome the aforementioned drawbacks.

An objective of the invention is to provide a styling device which is particularly ergonomic to use, regardless of the area of the head to be styled.

Another objective of the invention is to provide a hairstyling device which is particularly ergonomic to use, and this both for a user using the device on himself (user combing his hair himself) and for a user using the device. device on another person (user styling another person), and this on all parts of the hair.

Another objective of the invention is to provide a hairdressing device which is particularly simple and intuitive to use.

Another objective of the invention is to provide a hairdressing appliance which is particularly comfortable to use.

Another object of the invention is to provide a hairstyling appliance which is particularly safe.

Another object of the invention is to provide a hairstyling device which is particularly reliable and robust.

Another object of the invention is to provide a hairdressing appliance which is particularly economical to design and manufacture.

Another object of the invention is to provide a hairdressing appliance which is particularly easy to repair.

Another objective of the invention is to provide a hairdressing appliance which is particularly effective for shaping the hair, in particular for producing curls or waves or obtaining a "brushing" effect on these. last.

These objectives are achieved with the aid of a hairstyling device comprising:

- a main body comprising a handle extending longitudinally along a first axis,

- a device for moving the air to create an air flow between an air inlet and an air outlet,

an accessory intended to come into contact with the hair in order to shape the latter, said accessory extending longitudinally along a second axis, the main body comprising the air inlet at a free end and the accessory comprising the air outlet.

By handle is meant, for example, any element allowing a user to grip and manipulate the hairdressing appliance, such as a handle for example. The handle can advantageously form the main body or on the contrary be separated from the main body, while being connected to the latter. Preferably, the handle is aligned with the main body. In other words, the handle and the main body both extend along the first axis.

The hairdressing appliance is thus advantageously portable, that is to say that it can be transported and oriented in space according to the user's wishes.

Preferably, the accessory has a shape of revolution, and advantageously a cylindrical shape, which makes it possible to maximize the surface area coming into contact with the hair in order to shape it. In addition, such a shape facilitates the rotation of the accessory.

Advantageously, the accessory is removable, that is to say removable, that is to say that it is possible for the user to remove the accessory from the hairdressing appliance, that is to say that is to say to separate the accessory and the handle, for example to replace it with another accessory of a different size and / or shape. This allows the user to freely choose the hairstyle they will achieve on their hair, including being able to choose the diameter of the curls or waves they will achieve with the accessory. It can also allow the user to choose the most suitable accessory depending on the nature of their hair.

Advantageously, the accessory comprises a contact surface intended to serve as a winding surface for the hair and a plurality of pins projecting from said contact surface. Said plurality of pins allow the hair to be gripped and, combined with the rotation of the attachment, to wrap it well around the winding surface. Preferably, the contact surface is a surface of revolution, advantageously cylindrical thus forming a mandrel on which the hair can automatically wind under the effect of the rotation of the accessory.

According to the invention, said accessory is movable between at least two stable positions defined by design:

- a first position in which said second axis and first axis form a flat angle between them,

- a second position in which said second axis and first axis form between them an angle different from the flat angle.

Advantageously, each of said first position and second position guarantees the correct extraction of the air through the air outlet. In the preferred case where the hairdressing appliance comprises a drive motor, each of said first position and second position allows the accessory to rotate around said second axis

As is well known to those skilled in the art, the expression "flat angle" defines an angle of 0 ° or 180 °.

In other words, thanks to the invention, it is possible, advantageously at the initiative of the user of the apparatus, to arrange the accessory in two distinct and different positions. In the first position, said first axis and second axis form a flat angle: they are therefore either aligned (that is to say coincident) or parallel. Thus, in this first position, the accessory and the handle are either aligned (one being an extension of the other), (that is to say combined) or parallel. In the second position, said first axis and second axis form an angle which is not flat: they are therefore neither aligned, nor coincident, nor parallel. Thus, in this second position, the accessory and the handle form an elbow, one being inclined relative to the other. Advantageously, the positions retained are either a position in which the accessory is aligned with the main body, or a position in which the accessory is inclined relative to the main body.

Thus, thanks to said at least two positions of the accessory, it is possible for the user to orient the accessory as he wishes relative to the handle by which he holds the hairdressing appliance: the accessory is therefore orientable. .

This remarkably improves the ergonomics of the hairstyling appliance, in particular for a user who would use the hairstyling appliance on himself (a user who therefore combs his hair alone). Indeed, the user can use the hairdressing device which is the subject of the invention in the first position to carry out the shaping of his hair located on the side of his head, in a manner known as such. On the other hand, the user can also place the accessory of the hairdressing appliance which is the object of the invention in the second position to carry out the shaping of his hair located at the back of his head and / or on the sides. of the head. The fact that the handle and the accessory are then bent relative to each other will prevent the user from having to "break his arm" (that is to say, raise the shoulder in order to extend his arm perpendicular to his body, while folding his forearm completely back) to reach the hair arranged behind his head. The dispensation of this complex and uncomfortable movement greatly improves the ergonomics of the hairdressing device and avoids any pain for the user. Also, for the shaping of the hair arranged on the crown of his head, it is not necessary for the user to raise the shoulder and his arm (i.e. forming a right angle between his arm and body): by placing the accessory in the second position, the user can reach the top of his head while keeping his arm and shoulder alongside the body.

The ergonomics of the hairdressing appliance as defined by the invention is also optimized for a user who would use the hairdressing appliance on a third person, for example for a hairdresser who would perform a hairstyle on a client. Indeed, the user can place the accessory in the second position to easily reach the hair located on the top of the head of the person to be styled, while keeping his arm along the body, a position which is particularly ergonomic. . In addition, it is then possible for the user to remain at the same height of the person he is wearing, relieving the user, for example, of having to stand.

Preferably, the accessory is movable between exactly the first position and the second position, that is to say that the accessory has only two possible positions each allowing the correct operation of the device, and in particular the correct extraction. air through the air outlet. In other words, there is no intermediate position allowing the correct operation of the device between the first position and the second position.

Said first position and second position are stable positions defined by design. In other words, the first position and the second position are pre-existing positions, defined by the designers of the device, in which the accessory is automatically held. This guarantees the user that they can only select the best positions of the device, those which guarantee the best ergonomics, positions which will have been carefully defined in advance by the designers of the device. That is particularly suitable for people new to hairdressing operations. Thus, the user cannot define said first position and second position, he can simply change the accessory between one and the other, the accessory being automatically held either in the first position or in the second position. . This is particularly advantageous for a user who does not have any particular knowledge in terms of ergonomics or hairstyle, thus limiting the risk of error for the user. The stability of the accessory alternately in one and the other of said first and second position, for its part, ensures that the accessory is properly maintained in the position chosen by the user (in this case the first or the second) , regardless of the force applied to the accessory. This therefore prevents any accidental or unwanted movement of the accessory, in particular during hair styling operations where significant forces can be exerted on the accessory, forces which tend to cause the accessory to move and therefore cause it to leave its place. position.

Advantageously, the second axis forms an angle a different from the right angle with the first axis when the accessory is in the second position. In other words, when the accessory is in the second position, the angle formed between the first axis and the second axis is different from 90 °. This helps to improve the ergonomics of use of the hairstyling device as explained above. For example, said angle a is between 100 ° and 170 °, preferably between 130 ° and 170 ° and advantageously equal to 150 °. Indeed, the designers of the device have noticed that these angle ranges were particularly advantageous for optimizing the ergonomics of the hairdressing device, whether for a user using the device on himself or for a user. using the device on a third party, as explained above.

According to an advantageous embodiment, the main body comprises an articulation located between, and connecting, the handle and the accessory. Thus an articulation arranged between the handle and the accessory allows the user to move the accessory between the first position and the second position as he wishes. and with ease. Preferably, the joint then comprises a first inclined side and a second inclined side, said first inclined side and second inclined side being movable with respect to each other so as to cause the accessory to move between said first position and second position. The use of inclined sections to produce the articulation makes it possible to have a robust, reliable, inexpensive and easy to use articulation.

According to this embodiment, and in the advantageous case where said first and second positions are stable positions, the articulation preferably comprises a locking device movable between a free position, allowing the accessory to move between said first position and second position, and a locked position locking said accessory in one of said first position or second position (that is to say alternately in one and the other of said first and second position), position having been chosen by the 'user,. The locking device is then advantageously actuated by the user when he wishes to cause the accessory to move from the first position to the second position or vice versa. Such a locking device makes it possible to ensure the automatic maintenance of the accessory in one or other of said first or second positions (that is to say alternately in one and the other of said first and second position) according to the user's wishes, in a safe, reliable and inexpensive manner. In order to improve the intuitiveness of handling the device, said free position is preferably an unstable position while said locked position is a stable position. This therefore encourages the user to systematically place the accessory either in the first position or in the second position, strongly dissuading him (not to say prohibiting him) from placing the accessory in another position since the locking device will then refuse. to lock. This allows the novice user to easily select the best positions for using the device. This also guarantees that the accessory is held either in the first position or in the second position and prevents any unwanted evolution of the accessory: in fact, a positive action by the user is necessary on the locking device in order to be able to move the accessory from one position to the other.

According to one embodiment of the invention, the hairdressing appliance comprises a motor for driving the accessory in rotation about said second axis so that the hair can be wound around said accessory. Advantageously, the motor is an electric motor. However, it is conceivable, without departing from the scope of the invention, that the expression "motor" could denote a motor driven by another energy, such as, for example, pneumatic, magnetic or even human energy.

Preferably, the motor for driving the accessory in rotation is located inside said accessory. This embodiment is particularly well suited in the advantageous case where the accessory is hollow. This makes it possible to have the drive motor in rotation of the accessory outside the main body, and in particular outside the handle, and therefore to reduce the size of the latter, in particular its diameter, which further improves the ergonomics of the device.

The hairdressing appliance comprises a device for moving the air between an air inlet and an air outlet. Thus, the hairdressing appliance is then advantageously designed to blow air in the direction of the hair in order to dry and / or shape the latter. Preferably, the main body includes the air inlet and the accessory includes the air outlet. More preferably still, the handle can include the air inlet. The path for the air flow can then be as follows: the air is sucked in by an air inlet, advantageously located at one end of the handle, passes into the main body, then into the accessory, before be evacuated through the air outlet. Advantageously, the air outlet comprises a plurality of holes, which has the effect of uniformly diffusing the air towards the hair.

Preferably, the hairdressing appliance comprises an air heating device, advantageously placed inside the main body, and preferentially inside the handle. This then makes it possible to heat the air drawn in by the air inlet in order to blow hot air through the air outlet in the direction of hair. This makes it possible to dry and / or shape the hair in a particularly efficient and rapid manner.

The embodiment of the invention illustrated by the various figures is an embodiment in which the hairdressing appliance which is the subject of the invention is a blower brush, that is to say, an appliance combining the drying functions and hair brushing. More precisely, the device illustrated is a rotating blower brush, that is to say that the device, in addition to being able to blow hot air, has a rotating accessory making it possible to make curls or waves. in the hair, as will be detailed later.

As can be seen in Figures 1 to 7, the hairdressing appliance comprises a main body 1. As is well known to those skilled in the art, this main body 1 forms a housing grouping together the main components of the appliance. hairdressing. In particular, the main body 1 comprises an air heating device, such as a heating element for example, but also a device for setting the air in motion, such as for example an electric motor and fan assembly (or propeller) , which makes it possible to create an air flow between an air inlet 110 and an air outlet 24. This construction is well known to those skilled in the art so that it will not be further detailed here.

The main body 1 also includes an air inlet 110 located at the free end of the main body 1 as can be seen in the figures. Such an air inlet is typically used on hair styling devices of the "blower brush" type. It is therefore through this air inlet 110 that the air is drawn in by the device for setting the air in motion, heated by the device for heating the air, and then extracted from the main body 1 by the end connected to an accessory 2, as will be detailed later. The air inlet 110 typically comprises a grille, advantageously removable, intended to prevent foreign bodies (such as hair for example) from being sucked in by the device for setting the air in motion.

The main body 1 can be formed from two half-shells assembled together so as to facilitate the operations of assembly, disassembly, repair or maintenance of the apparatus. The main body 1 extends longitudinally along a first axis PP 'as illustrated by Figures 6 and 7. As can be seen, the main body extends between a free end (that is to say which does not is not connected to other parts) and one end intended to receive an accessory, as will be detailed later. More precisely, the main body 1 has a shape of revolution about the first axis P-P ', in particular a cylindrical shape. This makes it possible to combine the ergonomic and reception functions of the various components, as explained previously.

The main body 1 comprises a handle 11 intended to be gripped by the user. Thus, it is through this handle 11 that the user can easily grip the main body 1 and manipulate the hairdressing device. As can be seen in Figures 1 to 7, the handle 11 is part of the main body 1 and is formed by a region of reduced diameter of the main body 1 in order to facilitate its grip by the hand of the user. Thus, the handle 11 and the main body 1 both extend along the first axis P-P ′, preferably by being coaxial.

The main body 1 includes a first controller 111 designed to control the air movement device and the air heater. More precisely, the first control device 111 is a sliding button with several positions, four in this case: an off position, a cold air blowing position (that is to say that the heating device of the air is not activated, only the air movement device being activated), a position corresponding to an intermediate level of heating and air flow (i.e. the heating device and the device for moving the air are not at full power) and a position corresponding to a maximum level of heating and air flow (i.e. the heater and the device of air movement are at full power).

The main body 1 also comprises a second control device 112 which makes it possible to control the rotation of an accessory 2, as will be detailed below. More precisely, the second control device 112 comprises two push buttons arranged side by side, each corresponding to one direction of rotation of accessory 2: clockwise or counterclockwise. It is then up to the user to select the appropriate direction of rotation according to the hairstyle he wishes to achieve (direction of curls or waves in particular) and according to his direction of use of the hairstyling device.

It can be seen in the figures that the main body 1 is connected to a power cord 3 so as to provide adequate energy to the various components of the hairdressing appliance, in particular the device for setting the air in motion or the air heater. The power cord 3 is in this case an electric cord making it possible to supply the components with electrical energy but one could imagine other types of power cords, such as for example a pneumatic cord for supplying air to pneumatic components. . One could also imagine, without departing from the scope of the invention, that the hairdressing appliance is supplied with energy by an internal source (a battery for example), so that it would then have no power cord 3.

The hairdressing appliance also includes an accessory 2 intended to come into contact with the hair in order to shape the latter. The accessory is removable, as can be seen in Figure 7. As can be seen in Figures 1 to 6, the accessory 2 comprises a contact surface 21 intended to serve as a winding surface for the hair. More precisely, the contact surface 21 is a surface of revolution, and in particular a cylindrical surface so as to optimize the winding of the hair on the latter. Such a contact surface 21 in fact makes it possible to produce curls or waves or else a “brushing” effect on the hair. The contact surface 21 is made of a material which is a good thermal conductor (such as steel or aluminum for example) in order to diffuse the heat from the air to the hair. This helps to fix the shaping of the hair.

The accessory 2 extends longitudinally along a second axis A-A ’, as can be seen in Figures 6 and 7. More precisely, the accessory 2 has a shape of revolution around the second axis A-A’. Accessory 2 is hollow.

The accessory 2 also comprises a plurality of pins 23 projecting from said contact surface 21. By pins is meant any type of protuberance intended to grip the hair such as, for example, more or less rigid plastic rods or even tufts of synthetic or natural hair (in boar hair for example ). As can be seen in Figures 1 to 6, said plurality of pins 23 is regularly distributed over the contact surface 21 in rows. This improves the grip of the hair but also the good winding of the latter and finally the good release of the curl at the end of the shaping.

The accessory 2 also comprises an air outlet 24. The air outlet 24 then comprises a plurality of holes as can be seen in Figures 1 to 6. Said plurality of holes is then regularly distributed over the contact surface. 21, in particular by being arranged in the form of rows between the pins 23. This makes it possible to diffuse the air extracted from the hairdressing appliance well inside the hair, in a gentle and uniform manner. The diameter of each of the holes of the air outlet 24 decreases according to the direction of the air flow, that is to say decreasing from the main body 1 towards the free end of the accessory 2. This contributes to maintain a relatively constant flow of emitted air despite the increasing distance from the air inlet 110.

Accessory 2 includes a gripping tip 22 for gripping by the user when using the styling device. Said gripping end piece 22 is made of an insulating material so as not to transmit heat from the accessory 2 to the user's fingers. The gripping end piece 22 can be mounted to rotate freely relative to the accessory 2 in order to remain stationary in the user's fingers despite the rotation of the accessory 2. This makes it possible to improve the comfort of use of the accessory. the device but also the precision of the styling operation. The gripping end piece 22 also allows the operations of mounting and removing the accessory, as is known as such.

The hairdressing appliance also comprises a motor for driving the accessory 2 in rotation around said second axis A-A 'so that the hair can be wound around said accessory 2. More precisely, the motor is a electric motor, as is well known as such.

The motor for driving the accessory 2 in rotation is located inside said accessory 2. In other words, the motor for driving the accessory 2 in rotation is offset from the main body 1: the motor for driving in rotation. rotation, the accessory 2 is located outside the main body 1. This makes it possible, on the one hand, to save space inside the main body 1 and therefore, for example, to significantly reduce the diameter of the latter (which finally makes it possible to reduce the diameter of the handle 11 in the illustrated mode of illustration), and on the other hand, to improve the distribution of the masses within the hairdressing appliance. Indeed, according to this embodiment, the hairdressing appliance comprises a first motor inside the main body 1 (the drive motor of the device for setting the air in motion) and a motor inside of accessory 2 (the drive motor in rotation of the latter). The ergonomics and ease of use of the styling device are therefore improved.

More precisely, as can be seen in FIG. 7, the hairdressing appliance comprises an accessory support 4 which itself comprises the motor for rotating the accessory 2. The accessory 2 is therefore arranged around the support. accessory 4.

The accessory holder 4 comprises a proximal part 41 connected to the main body 1. As illustrated in FIG. 7 or FIG. 10, the proximal part 41 comprises an air guiding device 411. The air guiding device air 411 may in particular comprise fins, as illustrated, which then help straighten the air flow coming from the device for setting the air in motion, so as to create a laminar air flow. Alternatively, the air guiding device 411 can include arches.

The accessory holder 4 comprises a distal part 42 located opposite the proximal part 41. The distal part 42 is a free part, that is to say it is not connected to the main body 1 as can be seen in Figures 7 or 10. As can be seen in Figure 10, the distal part 42 comprises a device for driving in rotation 421 of the accessory 2. More precisely, the device for driving in rotation 421 of the accessory 2 comprises grooves intended to correspond with a complementary receiving device located inside the accessory 2, as is known to those skilled in the art. The distal part 42 also comprises a device for assembling and holding 422 the accessory 2 which itself comprises, for example, a groove. The groove is then intended to correspond with a complementary assembly and holding device located inside the accessory 2 as is known to those skilled in the art. The assembly and holding device 422 and the complementary assembly and holding device of the accessory also allow the user to dismantle the accessory, as is known as such.

Thus, the motor for driving the rotation of the accessory 2 is mounted inside the accessory support 4, the output shaft of said motor is connected to the device for driving in rotation 421 of the distal part 42 of the accessory support 4, said device for driving in rotation 421 itself being connected to the accessory 2 so as to transmit the rotational movement of said motor to the accessory 2. The proximal part 41 is also connected to the motor d 'drive in rotation of the accessory 2 insofar as the latter generally houses the electric cables supplying said motor.

As can be seen in the various figures, the main body 1 also includes an articulation 12. The articulation 12 is then located between the handle

11 and accessory 2. More precisely, the joint 12 is connected to the accessory support 4 and is disposed at one end of the main body 1. The joint

12 also makes it possible to connect the handle 11 and the accessory 2, or more precisely the accessory support 4. By articulation is meant any device allowing at least one angular displacement between two parts connected to one another. by said articulation 12, in this case, between the handle 11 and the accessory support 4, and therefore finally the accessory 2.

FIGS. 8 to 11 illustrate in detail an example of a joint used in the hairdressing device of the preceding figures. The articulation 12 comprises a first inclined face 121, that is to say a first part of which one face is inclined relative to the first axis P-P ′. The articulation 12 also comprises a second inclined face 122, that is to say a second part of which one face is inclined with respect to the second axis A-A '. Said first inclined face 121 and second inclined face 122 are parts of revolution, in particular cylinder portions, bevelled cylinders, as illustrated.

The first inclined face 121 extends longitudinally along the first axis P-P ’and around the first axis P-P’. The second inclined face 122 extends longitudinally along the second axis A-A ’and around the second axis A-A’.

The first inclined pan 121 is connected to the handle 11, as can be seen in Figures 6 and 7, while the second inclined pan 122 is connected to the accessory support 4, more precisely to the proximal part 41 of the latter. . Thus, the second inclined face 122 is connected (indirectly) to accessory 2.

Said first and second inclined sections 121, 122 are movable relative to each other, more particularly in a flat support movement, as illustrated in Figures 8, 9 and 11. In fact, as can be seen in FIG. 11, the first inclined side 121 comprises a first plane 1211 and the second inclined side 122 comprises a second plane 1221. Thus, by setting in motion said second inclined side 122 relative to the first inclined pan 121 (or vice versa), that is to say by creating a relative movement between said first inclined pan 121 and second inclined pan 122, the second plane 1221 will move on the first plane 1211 (or vice versa). As can be seen in FIG. 11, said first plane 1211 and second plane 1221 form portions of discs.

Said first inclined face 121 and second inclined face 122 are hooked to each other in order to maintain the joint 12 as a unitary piece. Indeed, as can be seen in Figure 11, the first inclined panel 121 comprises a guide and attachment device 1212 while the second inclined panel 122 includes a complementary guide and attachment device 1222.

More specifically, the guide and hooking device 1212 comprises a plurality of tabs projecting from the first plane 1211 towards the second plane 1221 of the second inclined face 122. The guide device and Complementary hooking 1222 comprises a groove, or a groove, produced on the second plane 1221, inside the second inclined face 122. Thus, said groove, or groove, receives said plurality of tongues. Each of the tongues has at its free end a hook so as to remain engaged in the groove or groove, as can be seen in FIG. 11. Thus, the guide and hooking device 1212 is designed to penetrate at least partially inside the complementary guide and hooking device 1222, which makes it possible to ensure the assembly between the first inclined face 121 and the second inclined face 122. Thus, the complementary guiding and hooking device 1222 is designed to receive the guiding and hooking device 1212 so as to ensure locking in translation but a degree of freedom in rotation. Indeed, the plurality of tongues of the guide and hooking device 1212 can slide inside the groove of the complementary guide and hooking device 1222, without however being able to be extracted therefrom, thanks to the hooks.

The articulation 12 can take at least two positions: a first position illustrated in FIG. 8 and a second position illustrated in FIG. 9. It is then understood that the first position of the articulation 12 in FIG. 8 corresponds to the first position of the joint. 'accessory 2 of Figure 1 or 2, while the second position of the joint 12 of Figure 9 corresponds to the second position of the accessory of Figure 3 or 4.

In the first position, the whole of the articulation 12 is oriented along the first axis P-P ', that is to say that the first inclined face 121 and the second inclined face 122 are both aligned with the first axis P-P '. In other words, the first slant 121 and the second slant 122 extend longitudinally along and around the first P-P axis. In the first position, the first plane 1211 and second plane 1221 are arranged in a staggered or "head-to-tail" fashion.

In the second position, part of the joint 12 is oriented along the first axis P-P 'and another part of the joint 12 is oriented along the second axis A-A'. Indeed, the first inclined face 121 extends along the and around of the first axis P-P 'while the second inclined face 122 extends along and around the second axis A-A'. In the second position, the first plane 1211 and second plane 1221 are not arranged staggered or "head to tail".

To move the articulation 12 from the first position to the second position, it is then necessary to perform a rotation of the second inclined face 122 with respect to the first (or vice versa) around the first axis P-P ', which will have the effect of effect of orienting the second inclined face 122 (or the first inclined face 121) along the second axis A-A 'instead of the first axis P-P'. Indeed, as explained above, the only degree of freedom existing between said first inclined side 121 and second inclined side 122 being a rotation, and, given said first plane 1211 and second plane 1221, both inclined, the articulation 12 will then leave its upright position to form an elbow, as can be seen in Figures 9 and 10.

Thus, the articulation 12 being connected on the one hand to the accessory 2 and on the other hand to the handle 11, the articulation 12 allows the accessory 2 to be movable between the first position and the second position, that is to say, allows the accessory 2 to be oriented either along the first axis P-P ', or along the second axis A-A', as can be seen in Figures 6 and 7 in particular . The accessory 2 can therefore, depending on the will of the user who is going to handle the device, either in the axis of the handle 11 or bent relative to the handle 11.

As shown in Figure 11, the joint 12 further comprises a locking device 123. The latter is then designed to lock the joint 12 in the first position or in the second position, that is to say to maintain the articulation 12 in one or the other of the positions, avoiding any untimely movement of the articulation 12. The locking device 123 is movable between two positions: a free position, allowing the accessory 2 to evolve between said at least first position and second position, and a locked position locking said accessory 2 in one of said first position or second position.

FIG. 11 illustrates this locking device 123 in detail. The latter thus comprises a third control device 1231, in this case a button pusher, intended to be manipulated by the user of the hairdressing appliance. The third control device 1231 projects radially from the first inclined face 121, so that it can be easily operated by the thumb or forefinger of the hand of the user who holds the hairdressing appliance by the handle 11 as can be done. understand it in Figures 1 to 4.

The locking device 123 also includes a lug 1232 connected to the third control device 1231. The lug 1232 protrudes longitudinally from the first plane 1211 of the first inclined face 121, in the same direction as the guiding and hooking device 1212. The lug 1232 is therefore arranged perpendicular to the third control device 1231. Thus, the lug 1232 is arranged perpendicular to the third control device 1231. 'lug 1232 is driven in a translational movement, vertical with reference to the figures, when the third control device 1231, in this case the push button, is actuated by the user.

The locking device 123 also comprises a first notch 1233 and a second notch 1234 each made in the second inclined face 122. Said first notch 1233 and second notch 1234 are diametrically opposed as can be seen in FIG. 11. Each of said first notch 1233 and second notch 1234 is then designed to alternately receive lug 1232.

The lug 1232 will then prevent the relative rotation between the first inclined face 121 and second inclined face 122, thus ensuring that the joint 12 is held in position, regardless of the force exerted on the accessory. Thus, when the lug 1232 is disposed in the first notch 1233, the articulation 12 is locked in the first position, that is to say that the entire articulation 12 is oriented along the first axis P-P ', that is to say that the accessory 2 and the main body 1 are aligned along the first axis P-P '. Said first inclined side 121 and second inclined side 122 are then arranged in a staggered manner or “head to tail” as explained previously. On the other hand, when the lug 1232 is disposed in the second notch 1234, the articulation 12 is blocked in the second position, that is to say that the second inclined face 122 is oriented along the second axis A-A ' , that is to say that the accessory 2 is oriented according to the second axis A-A 'and is therefore not aligned with the first axis P-P' of the main body 1.

By actuating the third control device 1231, the lug 1232 is moved in translation, the lug 1232 is found inside the complementary guiding and hooking device 1222, in this case inside the groove , which allows the relative rotation between the first inclined face 121 and second inclined face 122. It is then possible to rotate the joint 12 so as to make it pass from the first position to the second position or vice versa.

The locking device 123 also comprises an elastic return device, a spring for example (not shown), in the locked position. In other words, the free position is an unstable position while the locked position is a stable position. Thus, without action by the user on the third control device 1231, the articulation 12 is blocked, which prevents any undesirable movement of the latter, and therefore any undesirable movement of the accessory 2 relative to the main body 1. In addition, the elastic return device ensures automatic locking of the joint 12 in one or the other of the first or second position as soon as the lug 1232 arrives in front of one or the other of the first notches. 1233 or second notch 1234, that is to say as soon as the articulation 12 arrives in one or the other of the first or second position, that is to say as soon as the accessory 2 arrives in the 'either of the first or second position. This makes the use of joint 12 more intuitive.

As can be seen in Figure 11, the hinge 12 comprises an air channel 124 designed to allow the air flow from the air inlet 110 to the air outlet 24, the air being set in motion by the device for setting the air in motion, as explained above. More precisely, the air channel 124 comprises a tube 1241 which delimits said first planes 1211 and second plane 1221. In addition, the air channel 124 comprises a plurality of walls 1242, disposed radially inside the tube 1241. Said plurality of walls 1242 thus form different channels which make it possible to properly orient the air flow, in particular in a longitudinal direction. The walls 1242 make it possible in particular to reduce, or even eliminate, the rotating component or vortex of the air flow at the outlet of the device for setting the air in motion.

It is therefore understood, in the embodiment illustrated by the various figures, that the accessory 2 can move between said first position and second position, in particular thanks to the relative mobility between the first inclined side 121 and second inclined side 122. The accessory 2 can thus be moved between two positions:

- a first position in which said second axis A-A 'and first axis P-P' form between them a flat angle, that is to say a position in which the accessory 2 is in alignment with the body main 1 as can be seen in Figures 1, 2 and 5;

- a second position in which said second axis A-A 'and first axis P-P' form between them an angle different from the flat angle, that is to say a position in which the accessory 2 forms an elbow with the main body 1 as can be seen in Figures 3, 4 and 6.

More precisely, as shown in Figures 7 and 10, in the second position, the accessory support 4 is oriented along the second axis A-A ', that is to say it forms an angle with respect to - main body screw 1.

Thus, in particular thanks to the mobility of the articulation 12 and of the accessory support 4, each of the first and second positions allows the rotation of the accessory 2 by the motor for driving the accessory in rotation arranged at the end. 'inside the accessory holder 4.

As explained previously, according to the construction adopted in the embodiment illustrated and detailed above, the articulation 12 is designed to be movable between exactly two positions: the first position or the second position. Consequently, the accessory 2 is movable between exactly the first position and the second position. In other words, the accessory 2 is designed to operate normally, that is to say to be able to be rotated by the accessory drive motor, only in these two positions. This makes it possible to limit the number of scenarios for using the hairstyling device, which simplifies the use of the device for the user while offering him a device ergonomic. It also limits the costs of designing and manufacturing the styling device. Said first position and second position are stable positions defined by design, which prevents the user from having the accessory 2 in an inadequate position (in fact, there is no possible blocking in an intermediate position) and simplifies its handling of the hairdressing appliance, while limiting the design and manufacturing costs of the appliance.

One could however imagine, without departing from the scope of the invention, that the accessory 2 could move between three, four, five or a plurality of different positions, each of them allowing the rotation of the accessory 2 around the second. axis A-A '. One could also imagine that accessory 2 could move between, not different predefined positions, but an infinity of positions, that is to say that accessory 2 could work in any position. This will for example be possible with a flexible joint, comprising for example a cardan joint.

As can be seen from the illustrated embodiment, the second axis A-A ’forms an angle α different from the right angle with the first axis P-P’ when the attachment 2 is in the second position. More precisely, the angle a is equal to 150 ° as can be seen in FIG. 7. This is the angle formed between the main body 1, or the handle 11, and the accessory support 4, or accessory 2 itself. It has in fact been determined that this value makes it possible to offer a very ergonomic use for the user, in particular for the user who would use the styling device on himself (user combing his hair alone) and who would like to style the back of his head and / or possibly the sides of his head. However, it has also been determined that an angle of between 130 ° and 170 ° or even between 100 ° and 170 ° provides ergonomic use for the user.
