Description

Multi-function hair styling device with a rotary attachment lockable in position relative to the handle

Technical Field

The present invention relates to the general field of hair styling devices, for example for home use, and more particularly to the field of portable hair styling devices designed to blow air streams to dry hair and/or to promote hair styling.

Background

Hairdressing devices of the hand-held hair dryer type are known, which comprise a handle and a blowing head comprising an air outlet for directing a forced hot or cold air flow to the hair of a user. However, if such hair dryers are mainly used for drying damp hair by evaporation of water under the action of an air flow blown by the hair dryer (drying function), they can also be used in combination with a number of removable accessories aimed at facilitating hair styling (combing aid function). These accessories, which may be of the diffuser or concentrator type for example, are intended to be fixed to the head of the hair dryer and to be traversed by the air flow emitted by the blowing head, they form a joint that modifies the shape of the air flow emitted by the blowing head of the hair dryer.

These known hair dryers, although generally satisfactory, nevertheless have certain drawbacks. In particular, the transition of the hair dryer from the use mode for drying to the use mode for combing requires on the part of the user an assembly/disassembly operation of the accessory. Such operations can sometimes be cumbersome and there is also a risk of not being neglected in handling the accessories, of scalding and of losing the accessories if they are not simply stored in places that are not accessible and are not accessible when the user wishes to use them.

Detailed Description

The hair setting device 1 according to the present invention is a portable hair setting device designed to be grasped and manipulated by hand. It is a hairdressing apparatus which is preferably intended to be used in the home range by users without professional skills, in particular in hairdressing, that is to say in the drying and combing, styling of hair. Preferably, the hairdressing apparatus 1 is designed to be used by the user for himself, that is to say on his own hair, with the apparatus 1. However, it is fully contemplated that the device 1 could be designed for use by a user on the hair of a third person without departing from the scope of the present invention.

In the figures, a preferred embodiment of a hair setting device 1 is shown, said hair setting device 1 comprising a manually grasped handle 2 (or knob) intended to be manually grasped by a user for manipulating the hair setting device 1. The handle 2 extends between a first end 3 and an opposite second end 4, preferably longitudinally along a first axis a-a'. The hair dressing device 1 further includes: an on-board blower module 5 designed to generate (forced) airflow; and an attachment 6 (or a blowing head) connected to the handle 2, through which the air flow generated by the blower module 5 is to be guided out of the hair setting device 1 so as to be able to be projected toward the user's hair. The hair dressing device 1 is provided with an air inlet 7 through which ambient air can be sucked by the blower module 5 so as to blow in the direction of the user's hair. The blower module 5 advantageously comprises, in a known manner, a fan driven by an electric motor, the blower module 5 being arranged in the handle 2 or in the attachment 6. More preferably, however, the blower module 5 of the hairdressing device 1 is assembled to the handle 2 at the first end 3 of the handle 2. Advantageously, the attachment 6 is connected to the handle 2 at the second end 4 of said handle 2, and more advantageously, so that the attachment 6 extends said handle 2 starting from said second end 4, as in the embodiment shown in the accompanying figures. Preferably, the blower module 5 is fixed to the handle 2 at said first end 3 of the handle, without the possibility of the blower module 5 moving, in particular rotating, with respect to the handle 2. Accordingly, the blower module 5 is preferably remote from the attachment 6 and the handle 2. Thus, the blower module 5 can be dimensioned in an economical manner to produce an air flow with a high flow rate without affecting the overall size of the attachment 6 and the handle 2. In addition, this arrangement of the blower module 5 advantageously makes it possible to better balance the weight of the hairdressing apparatus 1 by mass distribution on either side of the handle 2, which contributes to ergonomics and comfort of use thereof. In the case of a blower module 5 arranged in the handle 2 or assembled to the handle 2 at the first end 3 thereof, the hairdressing apparatus 1 can then advantageously comprise a guide channel 8 arranged inside the handle 2, as envisaged above and shown in the drawings, to guide the air flow generated by the blower module 5 in the direction of the attachment 6.

Preferably, the hair setting device 1 further includes a heating element for raising the temperature of the air flow generated by the blower module 5. Loaded inside the hair dressing device 1, the heating element is arranged to be inserted in the air flow generated by the blower module 5. In the embodiment shown in the figures, the heating element is advantageously located in the guide channel 8 for the air flow provided in the handle 2, as described above. As is known, the heating element is generally an electric heating element, which operates according to the joule effect principle and comprises at least one heating resistor formed by an electric wire (not shown) wound around an insulating core 9. Alternatively, the heating element can be housed inside the accessory 6, but in particular is not conducive to the compactness of the latter.

Advantageously, the hairdressing apparatus 1 comprises a control and/or regulation device 10 for manually controlling and/or regulating the operation of the hairdressing apparatus 1, in particular the operation of its blower module 5 and/or heating element. It is an adjustment device, for example of the toggle switch type, push-button switch type and/or sliding or wheel transmission type 10, as in the example shown in figures 1 to 4, on which the user can act directly to electrically activate/deactivate the hairdressing device 1 and to change the rotation speed of the fan of the blower module 5, thus changing the speed/flow rate of the air flow blown by the accessory 6, and/or the heating temperature of the heating element. Such a manual control/regulation device 10, which is known per se, can be positioned, for example, at the handle 2 or at the blower module 5 when assembled at its first end 3 as in the example shown in fig. 1 to 4. Advantageously constituting a portable electrical appliance, the hairdressing apparatus 1 is preferably designed for being supplied with power from the mains via a power supply line 11. Alternatively, the hairdressing apparatus 1 can be powered by an on-board energy source (e.g., a battery) and can then be housed in the handle 2.

The attachment 6 of the hair setting device 1 according to the present invention is provided with the first air outlet 12 and the second air outlet 13 through which the air flow can be blown toward the hair of the user by the attachment 6. The first and

second air outlets

12, 13 are independent of each other and therefore do not coincide with each other. Said appendix 6 is mounted to rotate in a pivoting manner with respect to the handle 2 to transit between at least a first angular configuration (figures 1 and 5 to 7), in which the appendix 6 blows an air flow through the first air outlet 12, preferably only through said first air outlet 12, and a second angular configuration (figures 2 to 4 and 8 to 10), in which the appendix 6 blows an air flow through the second air outlet 13, preferably only through said second air outlet 13. In other words, the attachment 6 is mounted in a pivotally connected manner with respect to the handle 2 so as to be rotatable with respect to the handle 2, and the hair setting device 1 according to the present invention is designed and configured to allow a user to alternately select one or the other of the first and

second air outlets

12, 13 of the attachment 6 through which the attachment 6 will blow an air flow by pivoting the attachment 6 with respect to the handle 2.

Advantageously, the appendix 6 is mounted to rotate with respect to the handle 2 about a second axis B-B 'coinciding with the first axis of extension A-A' of the handle 2, as in the embodiment shown in the accompanying drawings. However, the second axis of rotation B-B 'may be parallel to said first axis A-A' and more or less offset with respect to the first axis. Thus, the kinematics of the attachment 6 are simple and reliable and allow the user to intuitively manipulate the hair setting device 1. Still alternatively, it is conceivable that the second axis B-B 'intersects the first axis A-A' at an angle, for example, between 5 and 15 or, for example, substantially equal to 90. As in the embodiment shown in the figures, the transition from the first to the second angular configuration of the appendix 6 may advantageously correspond to a rotation of the appendix 6 by an angle equal to 90 ° about the second rotation axis B-B'. However, the value of this angle is not limited in practice, and the transition of the appendage 6 from the first angular configuration to the second angular configuration may alternatively correspond, for example, to a rotation of the appendage 6 about the second rotation axis B-B' by an angle equal to 180 °.

According to a variant of the embodiment shown in the figures, the attachment 6 is designed to remain permanently fixed to the handle 2 of the hairdressing device 1 and therefore not to be released (in normal use) from the handle 2 of the hairdressing device 1 by the user. This makes it possible in particular to avoid the user losing his accessories of the hairdressing apparatus, since the latter are already available and mounted on the hairdressing apparatus. According to another variant, the accessory 6 is instead designed to be assembled to the handle 2 in a removable manner, so that the user can detach the accessory 6 from the handle 2, for example in order to clean or replace said accessory 6.

In particular, in the case where the blower module 5 is arranged inside the handle 2 or is assembled to the handle 2 as described above at the first end 3 thereof, the hairdressing apparatus 1 can further comprise an internal deflector 14, which is advantageously connected in a fixed and immovable manner with respect to the handle 2 and which is designed and configured for guiding the air flow generated by the blower module 5 through the attachment 6 from the guide channel 8 provided in the handle 2 towards the first air outlet 12 when the attachment 6 occupies said first angular configuration and, conversely, towards the second air outlet 13 when the attachment 6 occupies said second angular configuration.

Advantageously, the first and

second air outlets

12, 13 of the attachment 6 have openings of different geometries. In other words, the effective air passage cross section of the opening of the first air outlet 12 is defined by a profile (or profiles) of a shape different from the shape of the profile (or profiles) of the effective air passage cross section respectively defining the opening of the second air outlet 13. Thus, the air flow blown by the appendix 6 will advantageously have a different profile, according to the

air outlet

12, 13 selected.

Without departing from the scope of the present invention, it is conceivable that the first and

second air outlets

12, 13 are formed by accessory parts to each other, which are assembled in a removable manner (for example by snapping, screwing, pressing, etc.) to the rest of the accessory 6 mounted in rotation with respect to the handle 2. In fact, this will allow the user to provide the hair styling device 1 with two independent air outlets (instead of just one, as in conventional hair styling devices) with sections of different geometry, and thus to be able to use one or the other one of them in succession, without intermediate operations of disassembling/reassembling the parts, while still retaining the ability to replace one or the other of these accessory parts according to the user's wishes for the specific use of the hair styling device 1. Advantageously, however, the attachment 6 itself is instead formed as a tight whole, not detachable by the user, the first and

second air outlets

12, 13 being formed by one or more non-detachable parts belonging (in normal use) to the attachment 6. Thus, via rotation of the attachment 6 relative to the handle 2 of the device 1, a user can select one or the other of the first air outlet 12 (first angular configuration) or the second air outlet 13 (second angular configuration) without having to mount or dismount any attachment elements of the hair setting device 1. Thus, the user benefits from the easy and quick use of the device 1 and certainly does not lose any elements of the device.

Depending on the intended use of the hair setting device 1, it may be advantageous for at least one of the first and second angular configurations of the attachment 6 to correspond to a unique predetermined angular orientation (or position) of the attachment 6 relative to the handle 2. Thus, when the appendage 6 is not oriented according to this unique predetermined angular orientation or position with respect to the second rotation axis B-B', an air flow cannot be advantageously blown by the appendage 6 via the relative first or

second air outlet

12, 13. Such a feature has proved advantageous, in particular in the case where the hairdressing device 1 is designed to be used in a "blower" mode when the attachment 6 of the device 1 occupies one and/or the other of said first and second angular configurations, and where it is desired that an air flow is then blown by the attachment 6 along a predetermined unique average direction.

Alternatively or additionally, it is also advantageous that at least one of the first and second angular configurations of the attachment 6 allows the angular orientation of the attachment 6 relative to the handle 2 to be variable within a predetermined angular range, again depending on the intended use of the hair setting device 1. In other words, the first and/or second angular configurations referred to correspond in this case to a plurality of angular orientations (or positions) which the attachment 6 can assume within a bounded predetermined angular range (for example 20 ° to 60 °) relative to the handle 2. Thus, when the attachment 6 occupies such an angular configuration with a variable angular orientation, the attachment 6 has a degree of rotation about the second axis of rotation B-B' and is therefore able to pivot relative to the handle 2 within said bounded predetermined angular range, while blowing an air stream out of the hair setting device 1. Such a feature has proved advantageous, for example, in the case where the hairdressing device 1 is designed to be able to be used in a "blower" mode when the attachment 6 of the device 1 occupies one and/or the other of said first and second angular configurations, and where it is desired that an air flow can then be blown by the attachment 6 in a variable direction (for example, to allow blowing of hair by the air flow blown by the attachment 6 without the user performing a wrist movement holding the handle 2 of the hairdressing device 1).

More advantageously, the device 1 may be more specifically designed and configured to:

the second angular configuration (and/or respectively the first angular configuration) allows variable angular orientation of the appendix 6 with respect to the handle 2 according to the above-mentioned predetermined angular range, and

the corresponding second air outlet 13 (and/or the corresponding first air outlet 12, respectively) comprises at least a first and a second

air outlet portion

13A, 13B, which are preferably independent and non-contiguous.

The device 1 may then be configured in particular such that the accessory 6 is able to blow an air flow through one and/or the other of said first and

second portions

13A, 13B of the second air outlet 13 (and/or respectively the first air outlet 12) when the accessory 6 occupies said second angular configuration (and/or respectively said first angular configuration). In other words, depending on the angular position of the attachment 6 relative to the handle 2 within the predetermined angular range, an air flow may be blown by the attachment 6 either via the first portion 13A of the air outlet or via the second portion 13B of the air outlet or via both said first and

second portions

13A, 13B of the air outlet.

In the embodiment shown by way of example in the figures, the hairdressing device 1 is advantageously designed to transition between a "blower" mode (first angular configuration) and a "blowing brush" mode (second angular configuration) according to the angular configuration occupied by the attachment 6 mounted to rotate with respect to the handle 2 of the device 1.

Thus, the accessory 6 has a first face 15 which carries the first air outlet 12 of the accessory 6. As shown in particular in fig. 4, said first air outlet 12 advantageously has an elongated substantially oval opening (the air flow exits in the shape of an air knife). Alternatively, the first air outlet 12 may have, for example, a generally circular opening (the air flow exits in a substantially cylindrical or frustoconical shape). Thus, the hair setting device 1 can be advantageously used for drying hair when the attachment 6 occupies said first angular configuration with respect to the handle 2. Advantageously, as mentioned above, the first angular configuration corresponds to a unique predetermined angular orientation of the appendix 6 with respect to the handle 2. Thus, in the "blower" mode, according to the explanations given above, the accessory 6 advantageously blows an air flow in a predetermined unique average direction via the first air outlet 12.

In the embodiment shown by way of example in the figures, the appendage 6 also has a second face 16 which carries the second air outlet 13 of the appendage 6. Advantageously, the first and second faces 15, 16 are opposite one another, for example positioned on either side of the second rotation axis B-B' of the appendix 6 with respect to the handle 2. The appendix 6 is provided, at said second face 16, with mechanical engagement elements 17 of the hair, advantageously formed by rows or

bars

17A, 17B, 17C of bristles (or needles) of the brush. As shown in particular in fig. 3, 5 and 8, the second air outlet 13 of the accessory 6 comprises, as mentioned above, a first and a second

air outlet portion

13A, 13B, which are preferably separate and not contiguous. In this embodiment, the first and second

air outlet portions

13A, 13B form a longitudinal slit and are advantageously located on either side of the mechanical engagement elements 17 of the hair. However, the first and second

air outlet portions

13A, 13B may obviously have different shapes and positions. The second angular configuration of the attachment 6 of the hair setting device 1 shown in the drawings allows for a variable angular orientation of the attachment 6 relative to the handle 2 according to a predetermined angular range, unlike the first angular configuration. Furthermore, the hair setting device 1 is configured such that the attachment 6 can blow an air flow through one and/or the other of said first and

second portions

13A, 13B of the second outlet 13 when the attachment 6 occupies said second angular configuration. Thus, when the user uses the hair styling device 1 in the "air brush" mode, that is to say when the attachment 6 occupies its second angular configuration with respect to the handle 2, the interaction between the user's hair and the hair mechanical engagement elements 17 of the attachment 6 can cause pivoting of the attachment 6 with respect to the handle 2 along the second axis B-B'. This will advantageously have the following effect: depending on the direction of the combing of the hair and therefore on the direction of pivoting of the attachment 6 about the second axis B-B', an air flow is selectively blown through one or the other of the first and

second portions

13A, 13B of the second air outlet 13. In this way, the air flow will advantageously always be blown as close as possible to the user's hair, and always in the optimal direction according to the direction of movement of the device 1. Thus, in this case, the air flow will always be blown in a direction from the root of the hair towards the tip of the hair, which is particularly advantageous for certain operations for hair styling or for detangling operations.

Advantageously, the hair styling device 1 is also designed such that, in the absence of interaction between the user's hair and the hair mechanical engagement elements 17 of the attachment 6, the attachment 6 automatically returns to a known angular position, for example substantially in the middle of said predetermined angular range. For this purpose, a return means, such as a spring or a magnet, may optionally be provided between the handle 2 and the attachment 6, as will be discussed later.

In view of the above, the hair styling device 1 according to the present invention thus advantageously allows the user to select between at least a first mode of use (first angular configuration, for example for performing drying of the hair) and a second mode of use (second angular configuration, for example for performing combing of the hair) of the hair styling device 1 by a simple rotation of the accessory 6 with respect to the handle 2. Advantageously, the transition of the attachment 6 from one angular configuration to another is carried out by the user, who holds the handle 2 of the hairdressing device 1 with one hand and grasps the attachment 6 with the other hand in order to bring it into a rotational movement about its rotational axis B-B' relative to the handle 2.

Preferably, the accessory 6 comprises a hollow casing 18 (or housing), the outer surface of which substantially defines the outer shape and contour of the accessory 6 and advantageously of the end portion of the hairdressing device 1 connected to the handle 2 of said hairdressing device 1, so as to advantageously lengthen said handle 2. Advantageously, the casing 18 is shaped so as to allow the user to manually grip it, so that the user can directly manually perform a pivoting movement of said casing 18 (and therefore of the accessory 6) with respect to the handle 2 about the second axis of rotation B-B' of the accessory 6, as described above, to position said accessory 6 in one or the other of said first and second angular configurations, and thus select one or the other of said first and

second air outlets

12, 13 of the accessory 6, through which an air flow is to be blown out of the accessory 6.

In the embodiment shown by way of example in the figures, as envisaged above, the hair setting device 1 comprises an internal deflector 14 which lengthens the guide channel 8 for the air flow arranged inside the handle 2 in the axial direction beyond the second end 4 of the handle 2 (fig. 5 to 10). In this example, the casing 18 of the accessory 6 is substantially formed by two half-

shells

18A, 18B fixed to each other (for example by screwing or by snapping) which respectively define at least partially said first and second faces 15, 16 of the accessory 6. In order to allow the rotational assembly of the attachment 6 with respect to the handle 2, the second axis of rotation B-B ' of the attachment 6 advantageously coinciding with the first longitudinal extension axis a-a ' of the handle 2, the internal deflector 14 is provided, near the second end 4 of the handle 2, with an annular peripheral lip 19, advantageously extending in a plane orthogonal to the first axis a-a ' of the handle 2. Each half-

shell

18A, 18B of the casing 18 of the accessory 6 is provided at the inner surface with a

concave neck portion

20A, 20B complementary to the annular peripheral lip 19, so as to capture said annular peripheral lip 19, ensuring the rotational assembly of the accessory 6 when said half-

shells

18A, 18B are fixed to each other (fig. 6 and 9).

According to the invention, the hair styling device 1 further comprises locking means for locking the attachment 6 in at least one of said first and second angular configurations with respect to the handle 2, so as to inhibit the attachment 6 from assuming its first or second angular configuration. The hair setting device 1 according to the present invention further comprises a control member 21 to allow a user of the hair setting device 1 to control the locking and/or unlocking of the attachment 6 by the locking device.

Thus, the locking device is advantageously designed to be reversibly transformed between the following configurations:

a locking configuration in which said locking means mechanically inhibit any possibility of driving the accessory 6 in rotation along the second axis of rotation B-B' with respect to the handle 2 to cause the accessory 6 to exit the angular configuration in which it is locked, and

an unlocked configuration, in which said locking means in contrast allow to rotate the accessory 6 with respect to the handle 2 along said second axis of rotation B-B', so that the accessory 6 can be mechanically taken out of the one and/or the other angular configuration in which it is situated, to advantageously bring it into the other of said angular configurations which can be alternately taken up.

The transition from the locked configuration to the unlocked configuration and vice versa requires a positive action on the part of the user on the locking/unlocking control member 21 of the accessory 6, i.e. on the locking/unlocking control member of the accessory. Indeed, once the accessory 6 is locked in one and/or the other of the first and second angular configurations with respect to the handle 2, the accessory 6 will not be able to leave the angular configuration in which it is located without prior active action on the part of the user on the control member 21 to control the unlocking of the locking means. In particular, when the appendix 6 is in one and/or the other of said first and second angular configurations and the locking device is in the locking configuration, any manual rotation of the appendix 6 with respect to the handle 2 becomes impossible. This ensures the safety and comfort of use for the user in the sense of ensuring that the accessory 6 does not accidentally leave its position. This is particularly interesting when the attachment 6 is provided with hair engaging elements 17 as described above.

In the sense of the present invention, the control member 21 is functionally independent of the handle 2 and the attachment 6. In other words, although the control member 21 can be carried by the handle 2 and/or the attachment 6, integrated in the handle 2 and/or the attachment 6, as will be described in detail below, the latter does not constitute said control member 21 itself. In particular, the unlocking of the appendix 6 cannot be controlled by the user simply by exerting a force on the entire handle 2 and/or appendix 6. Instead, in order to allow the unlocking of the accessory 6, an intentional action on the part of the user on the control member 21 is required.

In the embodiment shown in the figures, the locking means are advantageously designed to lock the accessory 6 alternately with respect to the handle 2:

on the one hand, in said first angular configuration, in which the device 1 can be advantageously used in a "blower" mode when the accessory is in said first angular configuration, to inhibit the accessory 6 from leaving the first angular configuration, and

on the other hand, in said second angular configuration, in which the device 1 can be advantageously used in a "windbrush" mode when the appendage 6 is in said second angular configuration, to inhibit the appendage 6 from leaving the second angular configuration.

The possibility provided by the device 1 of locking the angular configuration of the accessory in the "blower" mode (first angular configuration) thus makes it possible, in particular, to advantageously avoid the accessory 6 rotating due to inertia and accidentally coming out of its first angular configuration "blower" when the user dries his hair using the device 1 by performing an alternating rotary motion of the wrist holding the handle 2 of the device 1. The possibility provided by the device 1 of alternately locking the angular configuration of the accessory in the "blowing brush" mode (second angular configuration) makes it possible in particular to avoid that the interaction between the user's hair and the hair mechanical engagement elements 17 of the accessory 6 when the user combs his hair using the device 1 results in sufficient force to pivot the accessory 6 about the second axis B-B and thus to move it away from its second angular configuration "blowing brush".

If it is therefore advantageous to design the locking means so as to allow the attachment 6 to be locked in each of the different angular configurations that the attachment 6 may occupy with respect to the handle 2, as in the embodiment shown in the accompanying drawings, it is nevertheless fully conceivable to provide such locking only for one of said first and second angular configurations, depending on the intended use of the device 1. However, the hair setting device 1 can optionally comprise limiting means for limiting the rotation of the attachment 6 with respect to the handle 2, when said attachment occupies said angular configuration which cannot be locked, so as to limit, but not completely inhibit, the ability of the attachment 6 to leave the "non-lockable" angular configuration it occupies. The limiting means may for example be formed by a pair of magnets, a pot hole or the like. Advantageously, said limiting means can also function as addressing means, allowing the user to know that the accessory 6 is indeed in the relative "non-lockable" angular configuration. However, by applying sufficient torque to the attachment 6 and the handle 2, it is still possible to move the attachment 6 out of the "non-lockable" angular configuration.

Such an implementation of the locking means for locking the angular configuration occupied by the attachment 6 with respect to the handle 2 thus avoids a certain number of practical inconveniences for the user in use and contributes to a high reliability of use of the hairdressing device 1. Furthermore, the locking device contributes to ensuring a particularly safe operation of the hair setting device 1, as long as it is capable of particularly avoiding an accidental projection of the flow of hot air in an undesired direction, for example in the direction of the eyes of the user, due to an undesired rotation of the attachment 6 which would cause it to change its angular configuration abruptly. By means of the locking means, the risk of overheating and damage to the device 1 is also limited, which can occur due to an undesired rotation of the accessory 6, which would bring it to an angular position outside said first and second angular configuration, and which acts to limit, or even completely inhibit, the projection of the air flow generated by the blower module 5 outside the hairdressing device 1 too strongly.

The hair setting device 1 according to the invention is therefore a portable hair setting device which is advantageously designed to be able to be used according to a plurality of different modes of use (multifunctional device), and which is not only particularly simple and practical to use, since the user can change the configuration/orientation of the accessory with respect to the handle to pass from one mode of use to another, but is also particularly reliable and safe in that the hair setting device 1 cannot leave the angular configuration in which it is situated during operation in situations which the user does not wish.

Advantageously, the unlocked configuration of the locking device is an unstable configuration such that when the locking device is in the unlocked configuration, the locking device tends to naturally return to its locked configuration. The safety of the hair styling device 1 is thereby increased, since without the user taking an active action on the control member 21 of the locking device, the locking device will tend to naturally resume its locking configuration and thus block the accessory 6 (as long as the accessory 6 then occupies one or the other of said first and second angular configurations that can be locked). Thus, the locking configuration of the locking device is advantageously a static configuration which can be occupied naturally without the user exerting a force on the control member 21.

Preferably, the locking means of the accessory 6 with respect to the handle 2 comprise at least one locking tongue 22 and at least one corresponding locking

groove

23, 24 for housing said locking tongue 22 therein when the locking means are in the locked configuration, the cooperation of the locking tongue 22 with the locking

grooves

23, 24 thus mechanically inhibiting the accessory 6 from leaving its occupied first or second angular configuration. In the unlocked configuration of the locking device, bolt 22 can no longer engage with

respective locking grooves

23, 24, so that there is no longer any obstacle to rotating accessory 6, and accessory 6 can then leave the first or second angular configuration it occupies. This configuration of the locking means has the advantage of being particularly easy to implement in reduced volumes. Advantageously, the locking

grooves

23, 24 are integral with the accessory 6 and the locking tongue 22 is integral with the handle 2, in order to simplify in particular the design of the accessory 6. However, the invention is of course not limited to this particular design of the locking means, and the locking means may be of any suitable alternative design (e.g. of the jaw type for clamping a surface of the accessory 6 against the handle 2 or other corresponding surface).

Although locking bolt 22 is thus intended to be received in

respective lock grooves

23, 24 in the locking configuration of the locking arrangement, the shape of locking bolt 22 is not particularly limited thereto. For example, as in the embodiment shown in the figures, locking tongue 22 may take the form of a rigid rod (or "pin") of circular section, which extends along a longitudinal axis, said rod being intended to follow this longitudinal axis for translational movement, i.e. sliding, between at least one position in which at least a portion of the rod is inside locking slot 23, 24 (locking configuration of the locking device) and one position in which the rod is instead completely outside said locking slot 23, 24 (unlocking configuration of the locking device).

In the case where at least one of said first and second angular configurations of the accessory 6 corresponds to a unique predetermined angular orientation of the accessory 6 with respect to the handle 2, in which it is desired to be able to lock the accessory 6, said locking slot 23 is advantageously shaped so as to be suitable for tightly housing said locking tongue 22 therein. In the locking configuration of the locking device, the bolt 22 is then captured in the locking groove 23 without significant play in the direction of rotation of the attachment 6 relative to the handle 2. However, if the periphery of the lock groove 23 is not necessarily closed, said lock groove 23 has at least a peripheral portion forming a stop for the bolt 22 in each of the two directions of rotation of the accessory 6. Obviously, it is possible to envisage the locking means comprising a plurality of pairs of bolts and corresponding locking grooves. In this case, the locking means will advantageously be configured such that each pair of bolt and keyway cooperates simultaneously with the other pairs of bolt and keyway. Furthermore, if each of said first and second angular configurations of the accessory 6 corresponds to a unique predetermined angular orientation of the accessory 6 with respect to the handle 2, at which it is desired to be able to lock the accessory 6, the locking means may advantageously comprise at least one locking tongue 22 and two independent corresponding locking grooves 23. As per the above, each of these locking grooves 23 is shaped so as to be suitable to receive alternately said locking tongues 22 therein, depending on whether the accessory 6 is in the first or in the second angular configuration (in which the accessory 6 should be locked).

In the case where at least one of said first and second angular configurations of the appendix 6 allows a variable angular orientation of the appendix 6 with respect to the handle 2 within a predetermined angular range-and where it is desired to be able to lock the appendix 6 in said angular orientation, said locking groove 24 advantageously forms an angular groove 24, i.e. an opening (or slot) in the shape of a circular arc, as shown in fig. 8. The length of said angular slot 24 then defines said predetermined angular range, and angular slot 24 is shaped so as to be suitable for accommodating therein said bolt 22 between two opposite ends 25, 26 of said angular slot 24 forming a stop. Once locking bolt 22 is received in said angular groove 24 in the locked configuration of the locking device, relative movement of locking bolt 22 and angular groove 24 (and therefore pivoting of accessory 6 relative to handle 2) is limited by the opposite ends 25, 26 of angular groove 24. According to a variant, bolt 22 is arranged directly against ends 25, 26 of angular groove 24. According to another variant, which will be described in greater detail below with reference to the embodiment shown in the accompanying drawings, bolt 22 is arranged to be received in an intermediate piece 27 movably mounted in said angular groove 24, in the locking configuration of the locking device. Locking bolt 22 is then able to indirectly interface with ends 25, 26 of angular slot 24 via respective opposite ends 28, 29 of movable intermediate member 27. Given that the device 1 is designed such that each of said first and second angular configurations of the accessory 6 allow an angular orientation of the accessory 6 with respect to the handle 2 that is variable within a predetermined angular range (the degree of variation need not be the same for each angular configuration) -and in which it is desired to be able to lock the accessory 6, the locking device may advantageously comprise at least one locking tongue 22 and two independent corresponding angular grooves 24. As per the above, each of these angular grooves 24 will be shaped so as to be suitable for receiving said bolt 22 alternately therein, depending on whether the accessory 6 is in the first or in the second angular configuration in which it should be locked.

According to a variant in the embodiment illustrated by way of example in the accompanying drawings, the locking means are advantageously arranged to (alternately) ensure that the appendix 6 is locked in the first angular configuration with respect to the handle 2 when the appendix 6 is in said first angular configuration, and correspondingly in the second angular configuration when the appendix 6 is in said second angular configuration. According to this variant, the locking means comprise a single bolt 22, a first lock groove 23 intended to receive therein said bolt 22 to lock the accessory in said first angular configuration, and a second lock groove 24 (independent of said first lock groove 23) intended to receive therein correspondingly said bolt 22 to lock the accessory 6 in said second angular configuration. Such a variant allows a particularly simple design of the locking means of the hairdressing device 1, since the same locking tongue 22 enables the accessories 6 to be locked alternately in each of the first and second angular configurations. In the embodiment shown by way of example in the accompanying drawings, the single bolt 22 of the locking device is formed by a rigid rod 22 (or "pin") of circular cross-section, as described above. Said rod 22 advantageously extends along a longitudinal axis along which it will move in translation, i.e. slide, when the locking device is transferred from the locking configuration to the unlocking configuration and vice versa. Said longitudinal extension axis of the rod 22 is advantageously oriented substantially parallel to a second rotation axis B-B' of the appendix 6 with respect to the handle 2. In this example, said second axis of rotation B-B ' coincides with, or is at least parallel to, the first axis of longitudinal extension a-a ' of the handle 2, so that the axis of longitudinal extension of the stem 22 is advantageously also substantially parallel to said first axis a-a ' (fig. 6, 7, 9 and 10).

More specifically, in the embodiment shown by way of example in the figures, the first angular configuration ("blower" mode) advantageously corresponds to a unique predetermined angular orientation of the accessory 6 with respect to the handle 2, while the second angular configuration ("blower brush" mode) advantageously allows a variable angular orientation of the accessory 6 with respect to the handle 2 within a predetermined angular range. Said first locking groove 23 of the locking means is advantageously shaped so as to be suitable for tightly housing a single locking tongue 22 therein to lock accessory 6 in said first angular configuration (figures 5 to 7). In this case, the first locking groove 23 is formed by a first cylindrical hole 23 of circular cross section, advantageously provided in the half-shell 18 of the housing 18, said half-shell 18 having the second face 16 (fig. 5 and 8). Advantageously, in order to limit the risk of shearing of locking bolt 22 under the effect of the forced rotation of appendix 6 along second axis B-B', a first cylindrical hole 23 is pierced which forms a first locking groove 23, and locking bolt 22 is dimensioned so that, when locking bolt 22 is tightly housed in the first locking groove in the locking configuration of the locking device, distal portion 30 of locking bolt 22 extends beyond said first locking groove 23. The annular peripheral lip 19 of the inner deflector 14 is advantageously provided with a first aperture 31 formed in the lower surface of the annular peripheral lip 19 facing said first lock groove 23 therethrough and intended to tightly receive therein said distal end portion 30 of the bolt 22 in the locking configuration of the locking device, as partially shown in fig. 6 and 7.

Said second locking groove 24 of the locking device advantageously forms an angular groove 24 (or slot in the shape of a circular arc), the length of which delimits said predetermined angular range, and which, according to the explanations provided above, is shaped so as to be suitable for accommodating therein a single locking tongue 22 between two opposite ends 25, 26 of the angular groove 24 forming the stop. As mentioned above, in the example shown in the figures, locking tongue 22 is not arranged in direct abutment with ends 25, 26 of angular groove 24, so as to inhibit accessory 6 from leaving said second angular configuration when the locking device is in the locking configuration. In fact, as can be seen more particularly in fig. 5 and 8, the appendage 6 comprises an intermediate piece 27 mounted movably inside said angular groove 24. Said intermediate piece 27 is mechanically connected to the accessory 6 by means of two traction springs 32, 33, the respective one end of which will rest on the surface of the half-shell 18A of the casing 18 with the first face 15 of the accessory 6, and the respective other end is connected to said intermediate piece 27. The

springs

32, 33 thus work against each other, so that the intermediate piece 27 can oscillate in the angular slot 24 between a first extreme position (not shown), in which one end 28 of the intermediate piece abuts against one of the ends 25 of the angular slot 24, and a second extreme position (not shown), in which the opposite end 29 of the intermediate piece 27 abuts against the other of the ends 26 of the angular slot 24. Intermediate piece 24 is provided with a second hole 34, advantageously equidistant from its

ends

28, 29, said second hole 34 being shaped so as to be suitable for tightly receiving bolt 22 therein, so as to lock accessory 6 in said second angular configuration (fig. 8 and 10), thus rotating accessory 6 to a certain extent along second axis B-B'. In this case, said

springs

32, 33 are advantageously calibrated to automatically return the intermediate piece 27 to the intermediate position inside the angular slot 24 (fig. 5 and 8). Said springs 32, 33 thus advantageously make it possible to define said angular position, known as the rest position, described above, in which the appendix 6 is able to return automatically when the appendix 6 is in said second angular configuration. Advantageously, in order to limit the risk of shearing of bolt 22 under the effect of the forced rotation of appendix 6 along second axis B-B', a second cylindrical hole 34 provided with intermediate piece 27 is pierced and bolt 22 is dimensioned so that, when bolt 22 is tightly housed in the second hole in the locking configuration of the locking device, said distal portion 30 of bolt 22 extends beyond said second hole 24. The annular peripheral lip 19 of the inner deflector 14 is advantageously provided with a second aperture 35 provided in the lower surface of the annular peripheral lip 19 facing said groove 24 and intended to tightly house said distal end portion 30 of the bolt 22 therein in the locking configuration of the locking device, as shown in fig. 9 and 10.

Optionally, according to a variant not shown in the figures, the angular groove 24 forming the second locking groove 24 may advantageously be provided with a third aperture positioned equidistant from the

ends

25, 26 of the angular groove 24, and wherein the distal portion 30 of the locking tongue 22 will be able to be tightly housed when the accessory 6 is locked in the second angular configuration. In this way, by engagement of locking tongue 22 with the third aperture provided in angular slot 24 (and with second aperture 34 of intermediate piece 24 when intermediate piece 24 is implemented), accessory 6 can advantageously be locked in the intermediate static angular position described above. Thus, if the user wishes, it may be advantageous to inhibit the attachment 6 from pivoting within said predetermined angular range when the attachment 6 is locked in said second angular configuration.

According to a preferred variant of the embodiment shown in the figures, the control member 21 of the locking device is a manual mechanical control member 21, which is connected (directly or not) to the bolt 22, so that the user can ensure locking and/or unlocking of the accessory 6 by the locking device by means of a direct manual action on the control member 21. Thus, the manual-mechanical control member 21 is advantageously mounted so as to be movable at least between a locking position in which the locking means occupy the locking configuration and an unlocking position in which the locking means occupy the unlocking configuration under the action of the control member 21. Such a variant has the benefit of being relatively simple to implement, inexpensive and reliable. Alternatively, it may be an automatic control member, on which the user will act indirectly to control the locking and/or unlocking of the accessory 6 by means of the locking means. Such automatic control means may then for example comprise an electromechanical relay connected on the one hand to the locking means and on the other hand to the control and/or adjustment means 10 for manually controlling and/or adjusting the operation of the hairdressing device 1 by the user. Thus, when the user opens the hairdressing device 1 by acting on the control and/or adjustment device 10, the automatic control means can, for example, automatically control the locking of the locking device in the angular configuration occupied by the attachment 6. The change of the angular configuration of the attachment 6 may then require the user to stop the operation of the hairdressing device 1 by acting again on the control and/or adjustment device 10, thus controlling the automatic unlocking of the attachment 6.

However, the following description will more particularly relate to the aforementioned preferred variant, wherein the control member 21 of the locking device is a manual mechanical control member 21.

Preferably, the manual mechanical control member 21 of the locking device is movably mounted on the handle 2, not on the attachment 6. In this way, the user can advantageously use his fingers holding the handle 2 of the device 1 to manipulate the manual mechanical control member 21, which contributes to giving the hairdressing device 1 particularly ergonomic features. It is also preferred that said manual mechanical control member 21 is mounted at one end of the handle 2, where the attachment 6 is connected to the handle 2, and more preferably that the attachment 6 extends said handle 2 from this end, in the example shown in the figures, in this case starting at said second end 4 of the handle 2. Such a positioning of the manual-mechanical control member 21, thus as close as possible to the interface between the rotary attachment 6 and the handle 2, allows in particular a simpler, more reliable and less bulky design of the mechanical connection between the manual-mechanical control member 21 and the locking means, in particular by limiting the need to resort to complex linkage arrangements. Different kinematics of the manual mechanical control member 21 may be considered. According to a particularly simple variant of the embodiment shown in the figures, the manual-mechanical control member 21 is advantageously mounted so as to be movable in translation, preferably in a straight line, along a first longitudinal extension axis a-a' of the handle 2. The manual mechanical control member 21 is then advantageously formed by a slide button 36, said slide button 36 being slidingly mounted in a slide slot 37 provided in the handle 2. According to another variant (not shown), the manual mechanical control member 21 may be mounted to be rotatably movable, preferably about a first longitudinally extending axis a-a' of the handle 2. According to a further variant (not shown), the manual mechanical control member 21 can be mounted with a translational and rotational movement, preferably along and around said first axis a-a', that is to say along a helical connection. In both variants, the manual mechanical control member 21 may be formed by an annular ring mounted in a rotary or pan-rotary manner inside a corresponding annular recess neck or groove provided in the handle 2. According to another less advantageous variant (not shown), the manual mechanical control member 21 can be mounted movable in translation along an intersecting direction (for example orthogonal) with respect to the first longitudinal extension axis a-a' of the handle 2. In this case, the manual mechanical control member 21 may be formed of a button.

According to a variant (not shown), the manual mechanical control member 21 and the locking tongue 22 (single or not) form a single integral part, which makes it possible in particular to simplify the design of the hairdressing apparatus 1 and to facilitate its assembly. According to another variant of the embodiment shown in the figures, manual mechanical control member 21 and locking bolt 22 (single or not) can form separate parts, which can then optionally be made of two different materials. The bolt 22 and the control member 21 are then directly or indirectly mechanically connected to each other. For example, locking bolt 22 may then be assembled to manual mechanical control member 21, for example, by screwing, gluing, press-fitting, or by overmolding. For example, manual mechanical control member 21 may be made of plastic in order to control, in particular, the overall weight of the device, while locking bolt 22 may be made of metal in order to, in particular, provide excellent mechanical strength, in particular shear strength.

Advantageously, the hair styling device 1 comprises resetting means arranged to automatically reset the manual-mechanical control member 21 to said locking position of the locking means when said manual-mechanical control member 21 occupies said unlocking position of the locking means (and when the user stops any direct action on the manual-mechanical control member 21). This ensures the advantageous unstable nature of the unlocked configuration of the locking device as described above. Preferably, said return means are elastic return means comprising at least one spring arranged to work in traction or compression to elastically return manual mechanical control member 21 to the locking position when it occupies said unlocking position. In the embodiment shown in the figures, said return means are elastic return means, which in this case advantageously comprise a pair of traction springs 38, 39 arranged between a surface of the handle 2 and a corresponding surface of the manual-mechanical control member 21, as can be seen from the transparent representation of the manual-mechanical control element 21 in fig. 7 and 10. Obviously, other return means, whether elastic (leaf spring, etc.) or non-elastic (pair of magnets, etc.), can be alternatively implemented to ensure such automatic return function of the manual mechanical control member 21 into the locking position of said locking means.

Advantageously, the unstable nature of the unlocked configuration of the locking means may allow the locking means to also function as an automatic addressing means of the accessory 6 in the first and/or second angular configuration, in which the accessory 6 can be locked by the locking means. This is because, when the user rotates the accessory 6 with respect to the handle 2 to position the accessory 6 in an angular configuration that can be locked, the locking device automatically transitions to the locking configuration, so that the user knows that he has reached the degree of rotation required to effectively position the accessory 6 in the desired angular configuration (either by hearing the noise emitted by the locking device, for example the engagement noise of the locking tongue 22 in the

respective locking groove

23, 24, or simply by suddenly counteracting the force exerted by the user to rotate the accessory 6).

The device 1 can also advantageously comprise visual and/or tactile markings 40 intended to inform the user of the direction of rotation in which the appendix 6 should be pivoted with respect to the handle 2, in order to position said appendix 6 in one or the other of said first and second angular configurations. Such marking means 40 may for example comprise a pair of opposite arrows 41 engraved, drawn or otherwise realized at the interface between the handle 2 and the appendix 6, in particular as shown in the example in fig. 3. Alternatively or additionally, said visual and/or tactile marking 40 may be provided for informing the user of the angular position of the attachment 6 with respect to the handle 2, which corresponds exactly to reaching one or the other of said first and second angular configurations. As shown in particular in fig. 3, the marking 40 may thus comprise, for example, a first marking 42, which first marking 42 protrudes from the outer surface of the slide button 35 of the control member 21 (or is engraved, drawn or otherwise realized on said slide button 35). The indicia 40 may also include second and

third indicia

43, 44 that protrude from (or are engraved, painted or otherwise implemented on) the outer surface of the housing 18 of the accessory 21, corresponding to one or more of the locking

grooves

23, 24 or the second aperture 34 by which the locking bolt 22 of the locking device will be received to ensure locking of the accessory 6. Said second and

third signs

43, 44 are advantageously positioned so as to visually correspond to the first signs 42 when the accessory 6 is in the first angular configuration or the second angular configuration, respectively (figure 3).

As described above in detail, the operation and use of the hair setting device 1 according to the present invention are, for example, as follows. The appendix 6 of the device 1 initially occupies, for example, its first angular configuration with respect to the handle 2 (corresponding to, for example, the "blower" use mode), in which said appendix 6 is preferably in a condition locked by the locking means of the device 1. The user then grasps the handle 2 of the device 1 with one hand, ready to position the device 1 so that the first air outlet 12 of the attachment 6 is directed towards his wet hair. The user then actuates the manual control and/or regulation means 10 for controlling and/or regulating the operation of the device 1, so as to blow a forced flow of air, preferably hot, in the direction of his hair via the first air outlet 12 of the attachment 6. Then, after having used the device 1 as such for a desired time, for example until reaching a certain degree of dryness or pre-dryness of its hair, the user acts on the control member 21 of the locking means of the accessory 6 to control the unlocking of the accessory 6 by means of the locking means. For example, the user slides the slide button 36 in the slide groove 37 of the manual mechanical control member 21 with a finger (e.g., thumb) of the hand holding the handle 2 to bring the slide button 36 from its locked position (high position in the drawing) to its unlocked position (low position). While thus keeping the accessory 6 unlocked, the user manually performs a rotational movement of the accessory 6 with respect to the handle 2 about the second rotation axis B-B' by holding the handle 2 with one hand and the accessory 6 with the other hand, until positioning the accessory 6 in its second angular configuration (corresponding for example to a "windmilling" mode of use). The user may then stop any action on the control member 21. Due to the advantageous unstable nature of the unlocked configuration of the locking device, the locking device then automatically transitions to the locked configuration, thus locking the accessory 6 in said second angular configuration. The user can then advantageously use the device 1 to comb, style his hair, for example by means of the hair engaging elements 17.
