Description

Technical Field

[0001] The present invention relates to the field of hairdressing appliances, in particular to the field of hairdressing appliances capable of forming curls and / or waves on the hair. The present invention particularly relates to the field of hairdressing appliances that blow hot air.

[0002] More specifically, the present invention relates to the technical field of hairdressing appliances comprising a main body, the main body comprising a handle extending longitudinally along a first axis, air flow means capable of forming an air flow between an air inlet and an air outlet, an attachment for coming into contact with hair to style the hair, the attachment extending longitudinally along a second axis, the main body comprising an air inlet at a free end and the attachment comprising an air outlet.

[0003] This type of appliance is often called a blower brush. Background Art

[0004] Hairdressing appliances that can straighten and / or make the hair fluffy and wavy are well known. These appliances are usually equipped with a rotating attachment forming a mandrel on which the hair can be styled or even wound. The mandrel is usually heated, which allows the style of the hair to be fixed. These appliances can blow hot air for heating the attachment on the one hand and the hair on the other hand, such as in the case of the appliance described in patent EP2131695 of the applicant, which forms a hair dryer brush.

[0005] This type of appliance has excellent results in hair styling and is therefore well received by users. However, this type of appliance sometimes presents some difficulties in use, particularly when the appliance is used by a person who wants to style his or her own hair.

[0006] This is because, when the user wants to style the hair located at the back of his head, he must perform complex movements with his arm, his forearm and his wrist to correctly position the appliance at the back of his head. The movements in question and the subsequent holding of the appliance in place are delicate, unintuitive and, above all, uncomfortable.

[0007] This is because, in order to properly position the prior art hair appliance behind his head, the user must raise his arms to shoulder height, extend them out to the side, while fully bending his elbows to position his forearms and hands behind his head. Finally, the user must typically bend his wrists to orient the attachments of the hair appliance in the correct position relative to his hair.

[0008] This can sometimes make the use of known devices complicated, uncomfortable, tiring or even painful, and sometimes even impossible, for people with joint or muscle problems. The physical effort required to use existing devices, especially behind the head, is therefore great and even painful.

[0009] Therefore, there is a need to improve existing appliances, particularly with respect to their ergonomics and comfort of use. Summary of the invention

[0010] The present invention is intended to overcome the above-mentioned disadvantages.

[0011] It is an object of the present invention to provide a hairdressing appliance which is particularly ergonomic to use, regardless of the area of ​​the head to be styled.

[0012] Another object of the present invention is to provide a hairdressing device that is particularly ergonomic to use, which is suitable for both a user who uses the device on himself (the user does his own hair) and a user who uses the device on another person (the user does another person's hair), and is suitable for all parts of the hair.

[0013] Another object of the invention is to provide a hairdressing appliance that is particularly simple and intuitive to use.

[0014] Another object of the present invention is to provide a hairdressing appliance which is particularly comfortable to use.

[0015] Another object of the present invention is to provide a particularly safe hairdressing appliance.

[0016] Another object of the invention is to provide a particularly reliable and robust hairdressing appliance.

[0017] Another object of the present invention is to provide a hairdressing appliance which is particularly economical to design and manufacture.

[0018] Another object of the present invention is to provide a hairdressing appliance which is particularly easy to repair.

[0019] Another object of the invention is to provide a hairdressing appliance which is particularly effective for styling the hair, in particular for creating curls or waves or obtaining a "combed" effect on these curls or waves.

[0020] These objectives are achieved using a hairdressing appliance comprising:

[0021] - a body comprising a handle extending longitudinally along a first axis,

[0022] - an air flow device capable of creating an air flow between the air inlet and the air outlet,

[0023] - an attachment for coming into contact with the hair for styling the hair, the attachment extending longitudinally along a second axis, the body comprising an air inlet at a free end and the attachment comprising an air outlet.

[0024] A handle is any element, such as a grip, that allows a user to grip and manipulate the hairdressing appliance. The handle may advantageously form the body, or on the contrary be separate from the body while being connected to the body. Preferably, the handle is aligned with the body. In other words, the handle and the body both extend along a first axis.

[0025] The hairdressing appliance is therefore advantageously portable, ie it can be transported and oriented in space according to the wishes of the user.

[0026] Preferably, the attachment has a revolving shape, advantageously cylindrical, which makes it possible to maximize the surface in contact with the hair to style it. In addition, this shape facilitates the rotation of the attachment.

[0027] Advantageously, the attachment is detachable, that is to say removable, that is to say the user can remove the attachment from the hairdressing appliance, that is to say separate the attachment from the handle, in order to replace it, for example, with another attachment of a different size and / or shape. This allows the user to freely choose the hairstyle he wants to achieve on his hair, in particular by being able to choose the diameter of the curl or wave he wants to achieve with the attachment. This also allows the user to choose the most suitable attachment according to the nature of his hair.

[0028] Advantageously, the attachment comprises a contact surface serving as a winding surface for the hair and a plurality of spikes protruding from said contact surface. Said plurality of spikes makes it possible to catch the hair and to wind it well on the winding surface in conjunction with the rotation of the attachment. Preferably, the contact surface is a rotating surface, advantageously cylindrical, thus forming a mandrel on which the hair can be automatically wound under the effect of the rotation of the attachment.

[0029] According to the invention, the accessory is movable between at least two stable and design-defined positions:

[0030] - a first position, wherein said second axis and the first axis form a straight angle between them,

[0031] - a second position, wherein said second axis and the first axis form between them an angle different from a straight angle.

[0032] Advantageously, each of the first and second positions ensures good extraction of air through the air outlet.

[0033] In the preferred case where the hairdressing appliance comprises a drive motor, each of said first and second positions allows the attachment to rotate about said second axis.

[0034] As is well known to those skilled in the art, the term "straight angle" is defined as an angle of 0° or 180°.

[0035] In other words, thanks to the invention, the accessory can advantageously be arranged actively by the user of the appliance in two discrete and different positions. In a first position, the first axis and the second axis form a right angle: they are therefore either aligned (i.e. coincident) or parallel. Thus, in this first position, the accessory and the handle are either aligned (one in extension of the other) (i.e. coincident) or parallel. In the second position, the first axis and the second axis form a non-right angle: they are therefore neither aligned, nor coincident, nor parallel. Thus, in this second position, the accessory and the handle form an elbow, one inclined relative to the other. Advantageously, the position maintained is either a position in which the accessory is aligned with the body, or a position in which the accessory is inclined relative to the body.

[0036] Thus, due to the at least two positions of the accessory, the user can orient the accessory at will relative to the handle by which he holds the hairdressing appliance: the accessory is thus orientable.

[0037] This significantly improves the ergonomics of the hairdressing appliance, in particular for a user who will use the hairdressing appliance on himself (and therefore a user who cuts his hair alone). This is because the user can use the hairdressing appliance as the subject of the invention in the first position to shape the hair on the side of his head in a manner known per se.

[0038] On the other hand, the user can also place the attachment of the hairdressing appliance that is the subject of the invention in the second position in order to style the hair located at the back of his head and / or at the sides of his head. The fact that the handle and the attachment are angled relative to each other will avoid that the user has to "bend his arms" (i.e. raise his shoulders in order to spread his arms perpendicular to his body while folding his forearms completely backwards) in order to reach the hair located at the back of his head. The avoidance of this complex and uncomfortable movement greatly improves the ergonomics of the hairdressing appliance and avoids any pain for the user. In addition, in order to style the hair on top of his head, the user does not need to raise his shoulders and arms (i.e. form a right angle between the arms and the body): by placing the attachment in the second position, the user can reach the top of his head while keeping his arms and shoulders along the body.

[0039] The ergonomics of the hairdressing appliance defined by the invention are also optimized for a user who will use the hairdressing appliance on a third person, for example a hairdresser who will style the hair of a client. This is because the user can place the attachment in the second position in order to easily reach the hair located on top of the head of the person to be styled, while keeping his arms along the body, a position that proves to be particularly ergonomic. Furthermore, the user can remain at the same height as the person whose hair he is styling, thereby saving the user from having to stand, for example.

[0040] Preferably, the accessory is movable strictly between a first position and a second position, i.e. the accessory has only two possible positions, each of which allows good operation of the appliance, in particular good extraction of air through the air outlet. In other words, there is no intermediate position between the first position and the second position that allows correct operation of the appliance.

[0041] The first position and the 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 designer of the appliance, in which the attachment is automatically retained. This ensures that the user can only select the best position of the appliance, i.e. the position that guarantees the best ergonomics, which positions will be carefully defined in advance by the designer of the appliance. This is particularly suitable for novices in hairdressing operations. Therefore, the user cannot define the first position and the second position, he can simply make the attachment transition between one and the other, and the attachment automatically remains in the first position or the second position. This is particularly meaningful for users without any specific knowledge of ergonomics or hairdressing, thereby limiting the risk of user errors. The stability of the attachment alternating between one and the other of the first and second positions ensures the proper retention of the attachment in the position selected by the user (in this case the first or second position), regardless of the forces applied to the attachment. Therefore, this avoids any accidental or undesired displacement of the attachment, in particular during hairdressing operations that may exert significant forces on the attachment, which tend to move the attachment and thus make it leave its position.

[0042] Advantageously, when the attachment is in the second position, the second axis forms an angle α with the first axis that is different from a right angle. In other words, when the attachment is in the second position, the angle between the first axis and the second axis is not 90°. This contributes to improving the ergonomics of using the above-mentioned hairdressing appliance. For example, said angle α is between 100° and 170°, preferably between 130° and 170° and advantageously equal to 150°. In fact, the designers of the appliance have noticed that these angle ranges are particularly advantageous for optimizing the ergonomics of the hairdressing appliance, both for a user using the appliance on himself and for a user using the appliance on a third person, as previously described.

[0043] According to an advantageous embodiment, the body comprises a joint between the handle and the accessory and connecting the handle and the accessory. Thus, the joint provided between the handle and the accessory allows the user to freely and easily transform the accessory between the first position and the second position. Preferably, the joint comprises a first inclined surface and a second inclined surface, which are movable relative to each other so as to transform the accessory between the first position and the second position. Using inclined surfaces to make the joint makes it possible to have a strong, reliable, cheap and easy to use joint.

[0044] According to this embodiment, and in the advantageous case that the first and second positions are stable positions, the joint preferably comprises a locking device movable between a free position, the free position allowing the accessory to be transferred between the first and second positions, and a locking position which locks the accessory in one of the first or second positions that has been selected by the user (i.e. alternately in one and the other of the first and second positions). The locking device is then advantageously actuated by the user when the user wishes to transfer the accessory from the first position to the second position or vice versa. Such a locking device makes it possible to ensure that the accessory is automatically kept in one or the other of the first or second positions (i.e. alternately in one and the other of the first and second positions) in a safe, reliable and inexpensive manner according to the user's wishes. In order to improve the intuitiveness of the operation of the appliance, preferably, the free position is an unstable position and the locking position is a stable position. Thus, this encourages the user to systematically place the accessory in the first or second position, strongly dissuading him (not to say prohibiting him) from placing the accessory in the other position, since the locking device will then refuse to lock. This allows a novice user to easily choose the best position for using the appliance. This also ensures that the accessory remains in the first position or the second position and avoids any undesired transformation of the accessory: this is because the user needs to take active action on the locking device in order to be able to transform the accessory from one position to the other.

[0045] According to an embodiment of the invention, the hairdressing appliance comprises a motor for driving the accessory in rotation about the second axis, so that hair can be wrapped around the accessory.

[0046] Advantageously, the motor is an electric motor. However, without departing from the scope of the present invention, it is contemplated that the term "motor" may refer to a motor driven by another energy source, such as pneumatic, magnetic or even human energy.

[0047] Preferably, the rotary drive motor of the accessory is located inside the accessory. This embodiment is particularly suitable for the advantageous case where the accessory is hollow. This makes it possible to arrange the rotary drive motor for the accessory outside the body, especially outside the handle, and thus reduce the size of the handle, especially its diameter, which further improves the ergonomics of the appliance.

[0048] The hairdressing appliance comprises means for causing air to flow 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 to ensure drying and / or styling of the hair. Preferably, the body comprises an air inlet and the attachment comprises an air outlet. More preferably, the handle may comprise an air inlet. The path of the air flow may be such that the air is sucked in by the air inlet, advantageously located at one end of the handle, into the body, then into the attachment, and then out through the air outlet. Advantageously, the air outlet comprises a plurality of holes, which has the effect of evenly diffusing the air in the direction of the hair.

[0049] Preferably, the hairdressing appliance comprises air heating means, which are advantageously arranged inside the body and preferably inside the handle. This then makes it possible to heat the air sucked in by the air inlet so as to blow the hot air through the air outlet in the direction of the hair. This makes it possible to dry and / or style the hair in a particularly effective and quick manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The embodiment of the invention shown in the figures is an embodiment in which the hairdressing appliance that is the subject of the invention is a blow-drying brush, i.e. an appliance that combines the functions of blow-drying and combing the hair. More specifically, the appliance shown is a rotating blow-drying brush, i.e. the appliance, in addition to being able to blow hot air, also has a rotating attachment that is able to form curls or waves in the hair, as will be described in detail later.

[0062] exist Figures 1 to 7 As can be seen in the figure, the hairdressing appliance comprises a main body 1. As is well known to those skilled in the art, the main body 1 forms a housing that combines the main components of the hairdressing appliance. In particular, the main body 1 comprises air heating means, such as a heating element, and also comprises air moving means, such as a motor and a fan (or propeller) assembly, which makes it possible to generate an air flow between the air inlet 110 and the air outlet 24. This structure is well known to those skilled in the art and will not be described in further detail here.

[0063] As shown, the main body 1 also includes an air inlet 110 located at the free end of the main body 1. Such air inlets are commonly used on "blowing brush" type hairdressing appliances. Therefore, it is through this air inlet 110 that air is sucked in by the air flow device, heated by the air heating device, and then extracted from the main body 1 through one end connected to the attachment 2, which will be described in detail later. The air inlet 110 usually includes a mesh, which is advantageously removable, for preventing foreign matter (such as hair) from being sucked in by the air flow device.

[0064] The body 1 may be formed of two half shells assembled to each other to facilitate assembly, disassembly, repair or maintenance operations of the appliance.

[0065] like Figure 6 and Figure 7As shown, the body 1 extends longitudinally along a first axis PP'. It can be seen that the body extends between a free end (i.e. not connected to other parts) and an end for receiving accessories, as will be described in detail below. More precisely, the body 1 has a shape of revolution around the first axis PP', in particular a cylindrical shape. As mentioned above, this makes it possible to combine ergonomic functions and the function of receiving various components.

[0066] The main body 1 includes a handle 11 for being grasped by a user. Therefore, through the handle 11, the user can easily grasp the main body 1 and manipulate the hairdressing appliance. Figures 1 to 7 As can be seen in the figure, the handle 11 constitutes a part of the body 1 and is formed by a region of the body 1 with a reduced diameter, so as to facilitate the user's gripping with the hand. Therefore, the handle 11 and the body 1 both extend along the first axis PP', preferably coaxially.

[0067] The body 1 comprises a first control device 111 designed to control the air movement device and the air heating device. More precisely, the first control device 111 is a sliding button having a plurality of positions, in this case four: a stop position, a cold air blowing position (i.e. the air heating device is not activated, only the air movement device is activated), a position corresponding to a medium heating and air flow rate (i.e. the heating device and the air movement device are not at full power) and a position corresponding to a maximum heating and air flow rate (i.e. the heating device and the air movement device are at full power).

[0068] The main body 1 also includes a second control device 112, which can control the rotation of the attachment 2, which will be described in detail later. More specifically, the second control device 112 includes two buttons arranged side by side, each button corresponding to the rotation direction of the attachment 2: clockwise or counterclockwise. The user then selects the appropriate rotation direction according to the hairstyle he wants to achieve (especially the direction of curls or waves) and according to the direction in which he uses the hairdressing appliance.

[0069] As can be seen from the figure, the body 1 is connected to a supply line 3 in order to provide sufficient energy for the various components of the hairdressing appliance, in particular the air flow device or the air heating device. In this case, the supply line 3 is an electric wire that can supply electrical energy to the components, but other types of supply lines can be considered, such as a pneumatic line for supplying air to pneumatic components. Without departing from the scope of the present invention, it is also possible to consider that the hairdressing appliance is supplied with energy by an internal source (such as a battery), so that it does not have a supply line 3.

[0070] The hairdressing appliance further comprises an attachment 2, which is used to come into contact with the hair to shape the hair. The attachment is detachable, such as Figure 7 As shown in Figures 1 to 6As can be seen in the figure, the attachment 2 comprises a contact surface 21 which serves as a hair winding surface. More precisely, the contact surface 21 is a surface of revolution, in particular a cylindrical surface, so as to optimize the winding of the hair on the surface. Such a contact surface 21 can actually create a curl or wave or "brush" effect on the hair. The contact surface 21 is made of a material that is a good thermal conductor, such as steel or aluminum, so as to diffuse the heat from the air to the hair. This helps to fix the style of the hair well.

[0071] The attachment 2 extends longitudinally along the second axis A-A', such as Figure 6 and Figure 7 More precisely, the attachment 2 has a shape of revolution about the second axis AA'. The attachment 2 is hollow.

[0072] The attachment 2 also comprises a plurality of thorns 23 protruding from the contact surface 21. A thorn is any type of protrusion for grabbing hair, such as a more or less hard plastic rod, or a tuft of synthetic or natural hair (e.g. boar hair). Figures 1 to 6 As can be seen in the figure, the plurality of thorns 23 are regularly distributed in rows on the contact surface 21. This improves the grip of the hair, and also improves the good winding of the hair, and finally the good escape from the curling hair at the end of the styling.

[0073] The attachment 2 also includes an air outlet 24. The air outlet 24 includes a plurality of holes, such as Figures 1 to 6 As shown. The plurality of holes are regularly distributed on the contact surface 21, in particular by being arranged in rows between the thorns 23. This makes it possible to diffuse the air extracted from the hairdressing appliance well into the hair in a gentle and uniform manner. The diameter of each hole of the air outlet 24 decreases in the direction of the air flow, that is, from the body 1 to the free end of the attachment 2. This helps to maintain a relatively constant exhaust air flow despite the increasing distance from the air inlet 110.

[0074] The attachment 2 comprises a gripping end piece 22 for being gripped by the user when using the hairdressing appliance. The gripping end piece 22 is made of an insulating material so as not to transfer heat from the attachment 2 to the user's fingers. The gripping end piece 22 can be mounted to rotate freely relative to the attachment 2 so as to remain stationary in the user's fingers despite the rotation of the attachment 2. This can improve the comfort of use of the appliance and also improve the precision of the hairdressing operation. The gripping end piece 22 also allows the attachment to be mounted and dismounted, as is known per se.

[0075] The hairdressing appliance further comprises a motor for driving the attachment 2 in rotation about said second axis AA' so that hair can be wound around said attachment 2. More specifically, the motor is an electric motor, as is well known per se.

[0076] The rotation drive motor of the accessory 2 is located inside said accessory 2. In other words, the motor for driving the accessory 2 in rotation is separated from the body 1: the motor for driving the accessory 2 in rotation is located outside the body 1. This makes it possible, on the one hand, to save space inside the body 1 and thus, for example, to significantly reduce the diameter of the latter (which ultimately makes it possible to reduce the diameter of the handle 11 in the example solution shown), and, on the other hand, to improve the mass distribution inside the hairdressing appliance. In fact, according to this embodiment, the hairdressing appliance comprises a first motor inside the body 1 (the drive motor of the air flow device) and a motor inside the accessory 2 (the rotation drive motor of the accessory 2). The ergonomics and the comfort of use of the hairdressing appliance are thus improved.

[0077] More specifically, if Figure 7 As shown, the hairdressing appliance comprises an accessory support 4, which itself comprises a motor for driving the accessories 2 in rotation. Thus, the accessories 2 are arranged around the accessory support 4.

[0078] The accessory support 4 includes a proximal portion 41 connected to the main body 1. Figure 7 or Fig.10 As shown, the proximal portion 41 comprises an air guiding device 411. As shown, the air guiding device 411 may include fins, which help to straighten the airflow from the air flow device, thereby generating a laminar airflow. Alternatively, the air guiding device 411 may include an arch.

[0079] The accessory support 4 includes a distal portion 42 opposite to the proximal portion 41. The distal portion 42 is a free portion, that is, it is not connected to the main body 1, such as Figure 7 or Fig.10 As shown. Fig.10 As can be seen in the figure, the distal portion 42 comprises a rotation drive means 421 of the accessory 2. More precisely, the rotation drive means 421 of the accessory 2 comprises a groove for corresponding with complementary receiving means located inside the accessory 2, as known to a person skilled in the art. The distal portion 42 also comprises an assembly and retaining means 422 of the accessory 2, which itself comprises, for example, a groove. This groove will then correspond with the complementary assembly and retaining means located inside the accessory 2, as known to a person skilled in the art. The assembly and retaining means 422 of the accessory and the complementary assembly and retaining means also allow the user to disassemble the accessory, as known per se.

[0080] Thus, the rotary drive motor of the accessory 2 is mounted inside the accessory support 4, the output shaft of said motor being connected to the rotary drive means 421 of the distal portion 42 of the accessory support 4, said rotary drive means 421 itself being connected to the accessory 2 in order to transmit the rotary movement of said motor to the accessory 2. The proximal portion 41 is also connected to the rotary drive motor of the accessory 2, since the latter usually houses the cable supplying said motor.

[0081] As can be seen in the figures, the body 1 also comprises a joint 12. The joint 12 is then situated between the handle 11 and the accessory 2. More precisely, the joint 12 is connected to the accessory support 4 and is arranged at one end of the 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. A joint is any device that allows at least an angular displacement between two parts connected to each other by said joint 12, in this case between the handle 11 and the accessory support 4 and therefore finally between the accessory 2.

[0082] Figures 8 to 11 An example of a joint used in the hairdressing appliance of the aforementioned figure is shown in detail. The joint 12 comprises a first inclined surface 121, i.e. a first part, one surface of which is inclined relative to the first axis PP'. The joint 12 also comprises a second inclined surface 122, i.e. a second part, one surface of which is inclined relative to the second axis A-A'. The first inclined surface 121 and the second inclined surface 122 are rotating parts, in particular parts of a cylinder, parts of a chamfered cylinder, as shown in the figure.

[0083] The first inclined surface 121 extends longitudinally along the first axis PP' and around the first axis PP'. The second inclined surface 122 extends longitudinally along the second axis AA' and around the second axis AA'.

[0084] The first inclined surface 121 is connected to the handle 11. Figure 6 and Figure 7 As shown, the second inclined surface 122 is connected to the accessory support 4, more precisely to the proximal portion 41 of the latter. Therefore, the second inclined surface 122 is (indirectly) connected to the accessory 2.

[0085] The first and second inclined surfaces 121, 122 can move relative to each other, more specifically according to the planar support movement, such as Figure 8 , Fig. 9 and Fig.11 In fact, Fig.11 As shown, the first inclined surface 121 includes a first plane 1211, and the second inclined surface 122 includes a second plane 1221. Therefore, by moving the second inclined surface 122 relative to the first inclined surface 121 (or vice versa), that is, by generating a relative movement between the first inclined surface 121 and the second inclined surface 122, the second plane 1221 will move to the first plane 1211 (or vice versa). Fig.11 As can be seen in the figure, the first plane 1211 and the second plane 1221 form a disc portion.

[0086] The first inclined surface 121 and the second inclined surface 122 hook each other to keep the joint 12 in the form of an integral part. Fig.11As shown, the first inclined surface 121 includes a guide and hook device 1212 , while the second inclined surface 122 includes a complementary guide and hook device 1222 .

[0087] More specifically, the guide and hook means 1212 comprises a plurality of tongues protruding from the first plane 1211 in the direction of the second plane 1221 of the second inclined surface 122. The complementary guide and hook means 1222 comprises a groove or a concave neck formed on the second plane 1221 inside the second inclined surface 122. Thus, the groove or concave neck receives the plurality of tongues. Fig.11 As shown, each tongue comprises a hook at its free end so as to remain engaged in the groove or the concave neck. Thus, the guide and hook means 1212 are designed to penetrate at least partially inside the complementary guide and hook means 1222, so as to ensure the assembly between the first inclined surface 121 and the second inclined surface 122. Thus, the complementary guide and hook means 1222 are designed to receive the guide and hook means 1212 to ensure translational locking but allow rotational freedom. In fact, the multiple tongues of the guide and hook means 1212 can slide in the groove of the complementary guide and hook means 1222, but cannot be extracted therefrom due to the presence of the hooks.

[0088] The joint 12 can adopt at least two positions: Figure 8 The first position shown and Fig. 9 The second position shown. It will then be understood that Figure 8 The first position of the connector 12 corresponds to Figure 1 or Figure 2 The first position of Annex 2, and Fig. 9 The second position of the connector 12 corresponds to Figure 3 or Figure 4 The second location of the attachment.

[0089] In the first position, the entirety of the joint 12 is oriented along the first axis PP', i.e., the first inclined surface 121 and the second inclined surface 122 are both aligned on the first axis PP'. In other words, the first inclined surface 121 and the second inclined surface 122 extend longitudinally along and around the first axis PP'. In the first position, the first plane 1211 and the second plane 1221 are staggered or "head-to-tail" arranged.

[0090] In the second position, a portion of the joint 12 is oriented along the first axis P-P', while another portion of the joint 12 is oriented along the second axis A-A'. In fact, the first inclined surface 121 extends along and around the first axis P-P', while the second inclined surface 122 extends along and around the second axis A-A'. In the second position, the first plane 1211 and the second plane 1221 are not staggered or "head-to-tail" arranged.

[0091] In order to transform the joint 12 from the first position to the second position, the second inclined surface 122 is rotated relative to the first inclined surface (or vice versa) about the first axis P-P', which will have the effect of orienting the second inclined surface 122 (or the first inclined surface 121) along the second axis A-A' instead of the first axis P-P'. In fact, as mentioned above, the only degree of freedom existing between the first inclined surface 121 and the second inclined surface 122 is rotation, and considering that both the first plane 1211 and the second plane 1221 are inclined, the joint 12 will then leave its straight position to form an elbow, as shown in FIG. Fig. 9 and Fig.10 shown.

[0092] Thus, the joint 12 is connected to the accessory 2 on the one hand and to the handle 11 on the other hand, and allows the accessory 2 to be moved between a first position and a second position, i.e. allows the accessory 2 to be oriented along the first axis PP' or along the second axis AA', in particular Figure 6 and Figure 7 Thus, the attachment 2 can be bent along the axis of the handle 11 or relative to the handle 11, according to the wishes of the user who is going to operate the device.

[0093] like Fig.11 As shown, the joint 12 also comprises a locking device 123. The locking device is then designed to lock the joint 12 in the first position or in the second position, that is to say to keep the joint 12 in one position or the other while avoiding any untimely movement of the joint 12. The locking device 123 is movable between two positions: a free position, which allows the accessory 2 to be transformed between said at least first position and second position, and a locked position, which locks said accessory 2 in one of said first position or second position.

[0094] Fig.11 The locking device 123 is described in detail. The locking device thus comprises a third control device 1231, in this case a button, which is intended to be operated by the user of the hairdressing appliance. The third control device 1231 protrudes radially from the first inclined surface 121 to facilitate actuation by the thumb or index finger of the user holding the hairdressing appliance by the handle 11, such as Figures 1 to 4 shown.

[0095] The locking device 123 also comprises a lug 1232 connected to the third control means 1231. The lug 1232 protrudes longitudinally from the first plane 1211 of the first inclined surface 121 in the same direction as the guide and hook means 1212. The lug 1232 is therefore arranged perpendicular to the third control means 1231. Thus, when the third control means 1231, in this case a button, is actuated by the user, the lug 1232 is driven to perform a translational movement, vertical in the drawing.

[0096] The locking device 123 further includes a first notch 1233 and a second notch 1234 respectively formed in the second inclined surface 122. The first notch 1233 and the second notch 1234 are radially opposite to each other. Fig.11 Thus, each of the first notch 1233 and the second notch 1234 is designed to receive the lugs 1232 alternately.

[0097] Thus, the lug 1232 will prevent relative rotation between the first inclined surface 121 and the second inclined surface 122, thereby ensuring that the connector 12 remains in place regardless of the forces applied to the accessory. Therefore, when the lug 1232 is placed in the first notch 1233, the connector 12 is locked in the first position, i.e. the entire connector 12 is oriented along the first axis PP', i.e. the accessory 2 and the main body 1 are aligned along the first axis PP'. As described above, the first inclined surface 121 and the second inclined surface 122 are thus staggered or "head-to-tail" arranged. On the other hand, when the lug 1232 is placed in the second notch 1234, the connector 12 is locked in the second position, i.e. the second inclined surface 122 is oriented along the second axis AA', i.e. the accessory 2 is oriented along the second axis AA' and is therefore not aligned with the first axis PP' of the main body 1.

[0098] By actuating the third control means 1231, a translational movement of the lug 1232 takes place, which is located in complementary guide and hook means 1222, in this case in a groove, which allows a relative rotation between the first inclined face 121 and the second inclined face 122. The joint 12 can then be rotated to pass from the first position to the second position, or vice versa.

[0099] The locking device 123 also includes elastic reset means, such as a spring (not shown), in the locked position. In other words, the free position is an unstable position, while the locked position is a stable position. Therefore, the user does not need to act on the third control device 1231, and the connector 12 is locked, which avoids any undesirable movement of the connector and thus avoids any undesirable movement of the accessory 2 relative to the body 1. In addition, once the lug 1232 reaches the opposite side of one or the other of the first notch 1233 or the second notch 1234, that is, once the connector 12 reaches one or the other of the first or second position, that is, once the accessory 2 reaches one or the other of the first or second position, the elastic reset means ensures the automatic locking of the connector 12 in one or the other of the first or second position. This makes the use of the connector 12 more intuitive.

[0100] like Fig.11As shown, the joint 12 comprises an air channel 124 designed to allow the air flow to pass from the air inlet 110 to the air outlet 24, as previously described, the air being caused to move by the air flow device. More precisely, the air channel 124 comprises a tube 1241 defining the first plane 1211 and the second plane 1221. In addition, the air channel 124 comprises a plurality of walls 1242, which are radially arranged inside the tube 1241. The plurality of walls 1242 thus form different channels, which make it possible to properly orient the air flow, in particular in the longitudinal direction. The walls 1242 can in particular reduce or even eliminate the rotation or vortex component of the air flow at the outlet of the air flow device.

[0101] It can therefore be understood that in the embodiments shown in the various figures, the accessory 2 can be transformed between the first position and the second position, in particular due to the relative mobility between the first inclined surface 121 and the second inclined surface 122. Therefore, the accessory 2 can be moved between two positions:

[0102] - a first position, in which the second axis AA' and the first axis PP' form a straight angle between them, i.e. a position in which the attachment 2 is aligned with the body 1, such as Figure 1 , Figure 2 and Figure 5 As shown;

[0103] - a second position, in which the second axis AA' and the first axis PP' form between them an angle different from a straight angle, i.e. a position in which the attachment 2 forms an elbow with the body 1, such as Figure 3 , Figure 4 and Figure 6 as shown in .

[0104] More specifically, if Figure 7 and Fig.10 As shown, in the second position, the accessory support 4 is oriented along the second axis AA′, ie it forms an angle with respect to the body 1 .

[0105] Each of the first and second positions therefore well allows the accessory 2 to be rotated by a rotary drive motor of the accessory arranged inside the accessory support 4 , in particular due to the mobility of the joint 12 and the accessory support 4 .

[0106] As described above, according to the structure adopted in the above detailed and illustrated embodiments, the joint 12 is designed to be movable strictly between two positions: the first position or the second position. Therefore, the attachment 2 is movable strictly between the first position and the second position. In other words, the attachment 2 is designed to operate normally only in these two positions, that is, it can be caused to rotate by the attachment drive motor. This makes it possible to limit the number of scenarios for using the hairdressing appliance, which simplifies the use of the appliance for the user while providing him with an ergonomic appliance. This also limits the design and manufacturing costs of the hairdressing appliance. The first position and the second position are stable positions determined by design, which prevents the user from placing the attachment 2 in an inappropriate position (this is because there is no possible locking in the intermediate position) and simplifies his operation of the hairdressing appliance while limiting the design and manufacturing costs of the appliance.

[0107] However, without departing from the scope of the present invention, it is contemplated that the accessory 2 can be transformed between three, four, five or more different positions, each of which allows the accessory 2 to rotate about the second axis A-A'. It is also contemplated that the accessory 2 is not transformable between different predetermined positions, but between an infinite number of positions, i.e. the accessory 2 can be operated in any position. This is possible, for example, with a flexible joint including, for example, a universal joint.

[0108] As can be seen in the embodiment shown, when the attachment 2 is in the second position, the second axis AA' forms an angle α with the first axis PP' that is different from a right angle. More precisely, the angle α is equal to 150°, as Figure 7 This is the angle formed between the body 1 or handle 11 and the accessory support 4 or the accessory 2 itself. In fact, it has been determined that this value can provide a very ergonomic use for the user, in particular for a user who will use the hairdressing appliance on himself (the user styles his own hair alone) and for a user who wants to style the back of his head and / or possibly the sides of his head. However, it has also been determined that an angle between 130° and 170° or even between 100° and 170° can obtain an ergonomic use for the user.
