Description

Technical Field

[0001] This invention relates to the general technical field of hair styling devices, such as those for home use, and more specifically to the field of portable hair styling devices designed for blowing airflow to dry hair and / or promote hair styling. Background Technology

[0002] Known handheld hair dryer-type hair styling devices include a handle and a blower head, the blower head including an air outlet for directing a forced hot or cold airflow to the user's hair. However, if such hair dryers are primarily used for drying damp hair by evaporation of water under the action of the airflow blown by the hair dryer (drying function), they can also be used in combination with a number of detachable attachments designed to facilitate hair styling (combing assistance function). These attachments (e.g., diffuser or concentrator type) are designed to be attached to the head of the hair dryer and passed through by the airflow emanating from the blower head; they form joints that alter the shape of the airflow emanating from the hair dryer head.

[0003] While these known hair dryers are generally satisfactory, they still have some drawbacks. In particular, the transition from drying to grooming requires the user to assemble / disassemble accessories. This can sometimes be cumbersome, and there is a significant risk of burns while handling the accessories. Furthermore, there is a risk of accessories being lost if they are not simply stored out of reach and cannot be accessed when needed. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a novel multifunctional portable hair styling device that is particularly practical, simple, reliable and safe to use even for users without professional skills (especially in hair styling).

[0005] Another object of the present invention is to provide a novel portable hair styling device that is ergonomically designed and particularly intuitive to use.

[0006] Another object of the present invention is to provide a novel portable hair styling device with a particularly simple and compact structure.

[0007] Another object of the present invention is to provide a novel portable hair styling device that is particularly robust and reliable.

[0008] Another object of the present invention is to provide a novel portable hair styling device that enables particularly effective hair drying and styling under comfortable use conditions.

[0009] The present invention achieves its objectives by means of a portable hair styling device comprising a hand-grip handle, an onboard blower module for generating airflow, and an accessory connected to the handle. The accessory is provided with a first air outlet and a second air outlet, which are different from each other. The accessory is mounted to rotate relative to the handle to switch between at least one first angular configuration and a second angular configuration. In the first angular configuration, the accessory blows airflow through the first air outlet, and in the second angular configuration, the accessory blows airflow through the second air outlet. The device further includes means for locking the accessory relative to the handle in at least one of the first angular configuration and the second angular configuration to prevent the accessory from leaving the first angular configuration or the second angular configuration in which it is located, and a control member for allowing the user of the device to control the locking and / or unlocking of the accessory via the locking means.

Detailed Implementation

[0021] The hair styling device 1 according to the invention is a portable hair styling device designed for hand gripping and manipulation. It is preferably intended for use at home by users without professional skills, particularly in hair styling, i.e., in drying, combing, and styling hair. Preferably, the hair styling device 1 is designed for use by the user on their own hair. However, without departing from the scope of the invention, it is entirely possible to design the device 1 for use on the hair of a third party.

[0022] The figure shows a preferred embodiment of a hair styling device 1, which includes a manually gripped handle 2 (or handle) designed for manual gripping by a user to operate the device. The handle 2 extends between a first end 3 and an opposing second end 4, preferably longitudinally along a first axis A-A'. The hair styling device 1 also includes: an onboard blower module 5 designed to generate (forced) airflow; and an accessory 6 (or blower head) connected to the handle 2, through which the airflow generated by the blower module 5 is directed out of the hair styling device 1 to be directed toward the user's hair. The hair styling device 1 is provided with an air inlet 7 through which ambient air can be drawn in by the blower module 5 to blow toward the user's hair. The blower module 5 advantageously includes a fan driven by an electric motor in a known manner, and can be arranged within the handle 2 or the accessory 6. However, more preferably, the blower module 5 of the hair styling device 1 is assembled to the handle 2 at the first end 3. Advantageously, attachment 6 is connected to handle 2 at the second end 4 of handle 2, and more advantageously, attachment 6 extends from the second end 4 of handle 2, as shown in the embodiment illustrated in the figures. Preferably, the blower module 5 is fixed to handle 2 at the first end 3 of handle, and the blower module 5 has no possibility of movement relative to handle 2, especially no possibility of rotation. Therefore, the blower module 5 is preferably located away from attachment 6 and handle 2. Thus, the size of the blower module 5 can be determined economically to generate an airflow with a high velocity without affecting the overall size of attachment 6 and handle 2. In addition, this arrangement of the blower module 5 advantageously allows for better balance of the weight of hair styling device 1 through mass distribution on either side of handle 2, which contributes to ergonomics and its user comfort. When the blower module 5 is disposed within handle 2 or assembled to handle 2 at the first end 3 of handle, as envisioned above and shown in the figures, hair styling device 1 can then advantageously include a guide channel 8 disposed within handle 2 to guide the airflow generated by the blower module 5 in the direction of attachment 6.

[0023] Preferably, the hair styling device 1 further includes a heating element for raising the temperature of the airflow generated by the blower module 5. Loaded inside the hair styling device 1, the heating element is arranged to be inserted into the airflow generated by the blower module 5. In the embodiment shown in the figures, as described above, the heating element is advantageously located within the airflow guide channel 8 disposed in the handle 2. It is well known that the heating element is typically an electric heating element that operates according to the Joule effect principle and includes at least one heating resistor formed by an electrical conductor (not shown) wound around an insulating core 9. Alternatively, the heating element can be housed inside the accessory 6, but this is particularly disadvantageous in terms of the latter's compactness.

[0024] Advantageously, the hair styling device 1 includes a control and / or adjustment device 10 for manually controlling and / or adjusting the operation of the hair styling device 1, particularly the operation of its blower module 5 and / or heating element. This is, for example, an adjustment device of the toggle switch type, push-button switch type, and / or slide or wheel gearbox type 10, such as... Figures 1 to 4 As shown in the example, the user can directly act on it to electrically activate / deactivate the hair styling device 1 and change the rotation speed of the fan in the blower module 5, thus changing the speed / flow rate of the airflow blown by accessory 6, and / or the heating temperature of the heating element. When as Figures 1 to 4 When assembled at its first end 3 as shown in the example, this known manual control / adjustment device 10 can, for example, be positioned at the handle 2 or the blower module 5. Advantageously constituting a portable electrical appliance, the hair styling device 1 is preferably designed for power supply from the mains grid via a power cord 11. Alternatively, the hair styling device 1 can be powered by an onboard power source (e.g., a battery), thus allowing it to be housed in the handle 2.

[0025] The accessory 6 of the hair styling device 1 according to the present invention is provided with a first air outlet 12 and a second air outlet 13, through which airflow can be blown by the accessory 6 toward the user's hair. The first and second air outlets 12 and 13 are independent of each other and therefore do not overlap. The accessory 6 is mounted to pivotally rotate relative to the handle 2 to be configured at at least one first angle ( Figure 1 and 5 (to 7) and a second angle construction ( Figures 2 to 4 The attachment 6 can switch between 8 and 10), in the first angle configuration, blowing air through the first air outlet 12 (preferably only through the first air outlet 12), and in the second angle configuration, blowing air through the second air outlet 13 (preferably only through the second air outlet 13). In other words, the attachment 6 is mounted relative to the handle 2 in a pivotal manner, thereby being able to rotate relative to the handle 2, and the hair styling device 1 according to the invention is designed and configured to allow the user to alternately select one or the other of the first and second air outlets 12, 13 of the attachment 6 by pivoting the attachment 6 relative to the handle 2, through which the attachment 6 will blow air.

[0026] Advantageously, accessory 6 is mounted to rotate relative to handle 2 about a second axis B-B', which coincides with the first extended axis A-A' of handle 2, as shown in the embodiment illustrated in the figures. However, the second axis of rotation B-B' may be parallel to the first axis A-A' and offset more or less relative to the first axis. Thus, the kinematics of accessory 6 are simple and reliable, and allow the user to intuitively manipulate the hair styling device 1. Alternatively, it can be envisioned that the second axis B-B' intersects the first axis A-A' at an angle, for example, between 5° and 15°, or for example, an angle substantially equal to 90°. As shown in the embodiment illustrated in the figures, the transition from the first angular configuration to the second angular configuration of accessory 6 may advantageously correspond to an angle of 90° rotation of accessory 6 about the second axis of rotation B-B'. However, this angle value is not practically limited, and the transition from the first angular configuration to the second angular configuration of accessory 6 may alternatively correspond, for example, to an angle of 180° rotation of accessory 6 about the second axis of rotation B-B'.

[0027] According to a variation of the embodiment shown in the accompanying drawings, accessory 6 is designed to be permanently held in place by the handle 2 of the hair styling device 1, and therefore will not (during normal use) be released from the handle 2 by the user. This particularly prevents the user from losing accessories to their hair styling device, as these are already available and installed on the device. According to another variation, conversely, accessory 6 is designed to be detachably assembled to the handle 2, allowing the user to separate accessory 6 from the handle 2, for example, for cleaning or replacement.

[0028] In particular, when the blower module 5 is arranged inside the handle 2 or assembled to the handle 2 at the first end 3 of the handle as described above, the hair styling device 1 may also include an internal deflector 14, which is advantageously connected to the handle 2 in a fixed and immovable manner, and is designed and configured to guide the airflow generated by the blower module 5 from the guide channel 8 provided in the handle 2 toward the first air outlet 12 through the attachment 6 when the attachment 6 occupies the first angular configuration, and conversely toward the second air outlet 13 when the attachment 6 occupies the second angular configuration.

[0029] Advantageously, the first and second air outlets 12 and 13 of Annex 6 have openings with different geometries. In other words, the effective air passage section of the opening of the first air outlet 12 is defined by a profile (or multiple profiles) of a different shape than the profile (or multiple profiles) defining the effective air passage section of the opening of the second air outlet 13, respectively. Therefore, depending on the selected air outlets 12 and 13, the airflow blown by Annex 6 will advantageously have different profiles.

[0030] Without departing from the scope of the invention, it is conceivable that the first and second air outlets 12, 13 are formed from accessory parts that are detachably assembled (e.g., by snapping, tightening, pressing, etc.) to the remainder of the accessory 6, which is rotatably mounted relative to the handle 2. In practice, this would allow the user to have two independent air outlets with different geometries (instead of just one, as with conventional hair styling devices) for the hair styling device 1, and thus be able to use one or the other sequentially without intermediate disassembly / reassembly of parts, while still retaining the ability to replace one or the other of these accessory parts according to the user's desired specific use of the hair styling device 1. Advantageously, however, the accessory 6 itself forms a tight integral unit that cannot be disassembled by the user, and the first and second air outlets 12, 13 are formed from one or more non-removable parts belonging to the accessory 6 (in normal use). Therefore, by rotating the accessory 6 relative to the handle 2 of the device 1, the 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 install or remove any accessory elements of the hair styling device 1. Therefore, users benefit from the ease and speed of using device 1, and are certain that no part of the device will be lost.

[0031] According to the intended use of the hair styling device 1, it is advantageous that at least one of the first and second angular configurations of the attachment 6 corresponds to a unique predetermined angular orientation (or position) of the attachment 6 relative to the handle 2. Therefore, when the attachment 6 is not oriented relative to the second axis of rotation B-B' according to this unique predetermined angular orientation or position, airflow cannot advantageously be blown by the attachment 6 via the associated first or second air outlet 12, 13. This feature has proven advantageous, particularly when the hair styling device 1 is designed for use in a "hair dryer" mode when the attachment 6 of the device 1 occupies one and / or the other of the first and second angular configurations, and when it is desired that airflow be blown by the attachment 6 along a predetermined unique average direction.

[0032] Alternatively or additionally, it is equally advantageous that, still depending on the intended use of the hair styling device 1, at least one of the first and second angular configurations of attachment 6 allows the angular orientation of attachment 6 relative to handle 2 to vary within a predetermined angular range. In other words, the first and / or second angular configurations involved in this case correspond to multiple angular orientations (or positions) of attachment 6 relative to handle 2 within a bounded predetermined angular range (e.g., 20° to 60°). Thus, when attachment 6 occupies such an angular configuration with a variable angular orientation, attachment 6 has a certain degree of rotation about the second axis of rotation B-B', and is therefore able to pivot relative to handle 2 within the bounded predetermined angular range while blowing airflow out of hair styling device 1. Such a feature has proven advantageous, for example, when hair styling device 1 is designed to be used in a "hair dryer" mode when attachment 6 of device 1 occupies one and / or the other of the first and second angular configurations, and it is desired that airflow can then be blown by attachment 6 in a variable direction (e.g., to allow the airflow blown by attachment 6 to sweep the hair without the user performing wrist movements to hold handle 2 of hair styling device 1).

[0033] More advantageously, device 1 can be designed and configured more specifically as follows:

[0034] - The second angle configuration (and / or correspondingly the first angle configuration) allows Annex 6 to be oriented at a variable angle relative to handle 2 within the aforementioned predetermined angle range, and

[0035] - The corresponding second air outlet 13 (and / or the corresponding first air outlet 12) includes at least first and second air outlet portions 13A, 13B, which are preferably independent and non-adjacent.

[0036] Therefore, the device 1 can be specifically configured such that when the attachment 6 occupies the second angular configuration (and / or correspondingly the first angular configuration), the attachment 6 can blow airflow through one and / or the other of the first and second portions 13A, 13B of the second air outlet 13 (and / or correspondingly the first air outlet 12). In other words, depending on the angular position of the attachment 6 relative to the handle 2 within a predetermined angular range, the airflow can 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 simultaneously via the first and second portions 13A, 13B of the air outlet.

[0037] In the embodiment shown as an example in the accompanying drawings, the hair styling device 1 is advantageously designed to switch between a "hair dryer" mode (first angle configuration) and a "blowing brush" mode (second angle configuration) depending on the angle occupied by an attachment 6 that is mounted to rotate relative to the handle 2 of the device 1.

[0038] Thus, Annex 6 has a first surface 15, which carries the first air outlet 12 of Annex 6. (As specifically in...) Figure 4 As shown, the first air outlet 12 advantageously has an elongated, generally elliptical opening (airflow exits in the shape of an air knife). Alternatively, the first air outlet 12 may have, for example, a generally circular opening (airflow exits in a substantially cylindrical or truncated conical shape). Thus, when the accessory 6 occupies the first angular configuration relative to the handle 2, the hair-drying device 1 can be advantageously used for drying hair. Advantageously, as described above, the first angular configuration corresponds to a unique predetermined angular orientation of the accessory 6 relative to the handle 2. Therefore, in "hair dryer" mode, as explained above, the accessory 6 advantageously blows airflow via the first air outlet 12 in a predetermined, unique average direction.

[0039] In the embodiment shown as an example in the accompanying drawings, Annex 6 further has a second surface 16, which carries the second air outlet 13 of Annex 6. Advantageously, the first and second surfaces 15, 16 are opposite each other, for example positioned on either side of the second axis of rotation B-B' of Annex 6 relative to the handle 2. Annex 6 is provided with a mechanical engagement element 17 for hair at the second surface 16, which is advantageously formed by rows or bars 17A, 17B, 17C of brush bristles (or needles). As particularly in Figure 3 , 5As shown in Figure 8, the second air outlet 13 of accessory 6 includes, as described above, first and second air outlet portions 13A, 13B, which are preferably independent and not adjacent. In this embodiment, the first and second air outlet portions 13A, 13B form longitudinal slits and are advantageously located on either side of the mechanical engagement element 17 of the hair. However, the first and second air outlet portions 13A, 13B can obviously have different shapes and positions. Unlike the first angular configuration, the second angular configuration of accessory 6 of the hair styling device 1 shown in the figures allows for a variable angular orientation of accessory 6 relative to handle 2 within a predetermined angular range. Furthermore, the hair styling device 1 is configured such that when accessory 6 occupies the second angular configuration, accessory 6 can blow airflow through one and / or the other of the first and second portions 13A, 13B of the second outlet 13. Therefore, when the user uses the hair styling device 1 in a "blowing brush" mode, that is, when accessory 6 occupies its second angular configuration relative to handle 2, the interaction between the user's hair and the mechanical engagement element 17 of accessory 6 can cause accessory 6 to pivot relative to handle 2 along the second axis B-B'. This will advantageously have the following effect: depending on the direction of hair combing and therefore the pivoting direction of Annex 6 around the second axis B-B', the airflow can be selectively directed through one or the other of the first and second portions 13A, 13B of the second air outlet 13. In this way, it will be advantageous to always direct the airflow as close as possible to the user's hair, and to always blow in the optimal direction depending on the direction of movement of the device 1. Thus, in this case, the airflow will always be directed from the root of the hair toward the tip, a direction particularly advantageous for certain hair styling operations or for untangling operations.

[0040] 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 element 17 of the attachment 6, the attachment 6 automatically returns to a known angular position, for example, substantially in the middle of the predetermined angular range. For this purpose, a reset device such as a spring or magnet may optionally be provided between the handle 2 and the attachment 6, which will be discussed later.

[0041] In view of the above, the hair styling device 1 according to the invention therefore advantageously allows the user to select between at least a first usage mode (first angle configuration, e.g., for drying hair) and a second usage mode (second angle configuration, e.g., for combing hair) of the hair styling device 1 by simply rotating the attachment 6 relative to the handle 2. Advantageously, the transition of the attachment 6 from one angle configuration to another is performed by the user, who holds the handle 2 of the hair styling device 1 with one hand and grasps the attachment 6 with the other hand to make it rotate about its axis of rotation B-B' relative to the handle 2.

[0042] Preferably, accessory 6 includes a hollow outer shell 18 (or housing), the outer surface of which substantially defines the external shape and profile of accessory 6, and advantageously defines the external shape and profile of the end portion of the hair styling device 1 connected to the handle 2 of the hair styling device 1, so as to advantageously extend the handle 2. Advantageously, the housing 18 is shaped to allow a user to manually grip it, so that the user can directly use his hand to pivot the housing 18 (and thus accessory 6) about a second axis of rotation BB′ of accessory 6 relative to the handle 2, as described above, to position accessory 6 in one or the other of the first and second angular configurations, and thus select one or the other of the first air outlet 12 and the second air outlet 13 of accessory 6 through which airflow will be blown outside accessory 6.

[0043] In the embodiment illustrated by way of example in the accompanying drawings, as envisioned above, the hair styling device 1 includes an internal deflector 14 that extends axially beyond the second end 4 of the handle 2, where an airflow guide channel 8 disposed inside the handle 2 extends. Figures 5 to 10 In this example, the outer shell 18 of accessory 6 is essentially formed by two half-shells 18A, 18B that are fixed to each other (e.g., by screwing or by snap-fit), the half-shells at least partially defining the first and second surfaces 15, 16 of accessory 6, respectively. To allow rotational assembly of accessory 6 relative to handle 2—with the second axis of rotation B-B' of accessory 6 advantageously coinciding with the first longitudinal extension axis A-A' of handle 2—the internal deflector 14 has an annular peripheral lip 19 near the second end 4 of handle 2, the annular peripheral lip advantageously extending in a plane orthogonal to the first axis AA' of handle 2. Each half-shell 18A, 18B of the outer shell 18 of accessory 6 has a concave portion 20A, 20B at its inner surface that complements the annular peripheral lip 19, in order to capture the annular peripheral lip 19, thereby ensuring rotational assembly of accessory 6 when the half-shells 18A, 18B are fixed to each other. Figure 6 and 9 ).

[0044] According to the present invention, the hair styling device 1 further includes a locking device for locking the accessory 6 relative to the handle 2 in at least one of the first angle configuration and the second angle configuration, thereby preventing the accessory 6 from being in the first or second angle configuration. The hair styling device 1 according to the present invention also includes a control member 21 to allow the user of the hair styling device 1 to control the locking and / or unlocking of the accessory 6 via the locking device.

[0045] Therefore, the locking device is advantageously designed to reversibly switch between the following configurations:

[0046] - A locking mechanism, wherein the locking device mechanically inhibits any possibility of driving attachment 6 to rotate relative to handle 2 along the second rotation axis BB′ to disengage attachment 6 from its locked position in one and / or the other angular configuration, and

[0047] - Unlocking configuration, wherein the locking device, on the contrary, allows attachment 6 to rotate relative to handle 2 along the second axis of rotation B-B', thereby mechanically allowing attachment 6 to exit one and / or another angular configuration in which it is located, so as to advantageously allow it to enter another of the angular configurations that can be alternately occupied.

[0048] The transition from the locking to the unlocking configuration, and vice versa, requires active user action on the locking / unlocking control member 21 of accessory 6. In fact, once accessory 6 is locked relative to handle 2 in one and / or the other of the first and second angle configurations, accessory 6 cannot leave its position without prior active user action on control member 21 to unlock the locking device. Specifically, when accessory 6 is in one and / or the other of the first and second angle configurations and the locking device is in the locked configuration, any manual rotation of accessory 6 relative to handle 2 becomes impossible. This ensures user safety and comfort in the sense that accessory 6 will not accidentally leave its position. This is particularly significant when accessory 6 is equipped with the hair-attaching element 17 as described above.

[0049] In the context of this invention, the control member 21 is functionally independent of the handle 2 and the accessory 6. In other words, although the control member 21 may be carried by the handle 2 and / or the accessory 6, or integrated within the handle 2 and / or the accessory 6, as will be described in detail below, the latter does not itself constitute the control member 21. Specifically, unlocking the accessory 6 cannot be controlled by the user simply by applying force to the entire handle 2 and / or the accessory 6. Instead, intentional action by the user on the control member 21 is required to allow unlocking the accessory 6.

[0050] In the embodiment shown in the accompanying drawings, the locking device is advantageously designed to alternately lock accessory 6 relative to handle 2:

[0051] On the one hand, in the first angle configuration, when the accessory is in the first angle configuration, the device 1 can advantageously be used in a "hair dryer" mode to prevent the accessory 6 from leaving the first angle configuration, and

[0052] - On the other hand, in the second angle configuration, when the attachment 6 is in the second angle configuration, the device 1 can be advantageously used in a "blowing brush" mode to prevent the attachment 6 from leaving the second angle configuration.

[0053] Therefore, the possibility provided by device 1 to lock the angular configuration of the attachment in the "hair dryer" mode (first angular configuration) makes it particularly advantageous to prevent attachment 6 from rotating due to inertia and accidentally leaving its first angular configuration "hair dryer" when the user uses device 1 to dry their hair by performing an alternating rotational movement of the wrist holding the handle 2 of device 1. The possibility provided by device 1 to alternately lock the angular configuration of the attachment in the "blowing brush" mode (second angular configuration) makes it particularly advantageous to prevent the interaction between the user's hair and the hair mechanical engagement element 17 of attachment 6 from causing sufficient force to cause attachment 6 to pivot about the second axis BB and thus leave its second angular configuration "blowing brush" when the user uses device 1 to comb their hair.

[0054] If it is therefore advantageous to design the locking device to allow attachment 6 to be locked in each different angular configuration that attachment 6 may occupy relative to handle 2, as in the embodiment shown in the figures, then it is still entirely conceivable to provide such locking only for one of the first and second angular configurations, depending on the intended use of device 1. However, hair styling device 1 may optionally include a limiting device for restricting the rotation of attachment 6 relative to handle 2—to limit, but not completely prohibit, the ability of attachment 6 to leave its occupied “unlockable” angular configuration when the attachment occupies an angular configuration that cannot be locked. The limiting device may, for example, be formed by a pair of magnets, a pit, etc. Advantageously, the limiting device may also function as an addressing device, thereby allowing the user to know that attachment 6 is indeed in the relevant “unlockable” angular configuration. However, by applying sufficient torque to attachment 6 and handle 2, it is still possible to make attachment 6 leave the “unlockable” angular configuration.

[0055] The implementation of such a locking device for locking the angular configuration occupied by the attachment 6 relative to the handle 2 thus avoids a certain number of practical inconveniences for the user during use and contributes to the high reliability of the hair styling device 1. Furthermore, the locking device helps ensure particularly safe operation of the hair styling device 1, provided that it can specifically prevent the accidental projection of hot airflow in undesirable directions, such as in the direction of the user's eyes, due to the undesirable rotation of the attachment 6 that would cause it to suddenly change its angular configuration. The locking device also limits the risk of overheating and damage to the device 1 that may occur due to the undesirable rotation of the attachment 6, which would cause the attachment to reach an angular position outside the first and second angular configurations, and its effect is to excessively restrict, or even completely prevent, the airflow generated by the blower module 5 from being projected outside the hair styling device 1.

[0056] Therefore, the hair styling device 1 according to the invention is a portable hair styling device, which is advantageously designed to be used in a variety of different modes of use (multifunctional device), and its use is not only particularly simple and practical because the user can change the construction / orientation of the attachment relative to the handle to switch from one mode of use to another, but also particularly reliable and safe because the hair styling device 1 cannot deviate from its angular construction during operation without the user's expectation.

[0057] Advantageously, the unlocking mechanism of the locking device is unstable, causing it to tend to naturally return to its locked position when in the unlocked position. This improves the security of the hair styling device 1, as the locking device will naturally return to its locked position without any active action by the user on the control member 21, thus blocking the accessory 6 (provided that the accessory 6 then occupies one or the other of the first and second angle configurations that can be locked). Therefore, the locking mechanism of the locking device is advantageously a static configuration that can be naturally occupied without the user applying force to the control member 21.

[0058] Preferably, the locking device of attachment 6 relative to handle 2 includes at least one latch 22 and at least one corresponding locking groove 23, 24, which is used to receive the latch 22 when the locking device is in the locked configuration. The engagement of the latch 22 with the locking groove 23, 24 mechanically prevents attachment 6 from leaving its occupied first or second angular configuration. In the unlocked configuration of the locking device, the latch 22 can no longer engage with the corresponding locking groove 23, 24, thus eliminating any obstacle to the rotation of attachment 6, and attachment 6 can then leave its occupied first or second angular configuration. This configuration of the locking device has the advantage of being particularly easy to implement in a reduced size. Advantageously, the locking groove 23, 24 is integral with attachment 6, and the latch 22 is integral with handle 2, in order to particularly simplify the design of attachment 6. However, the invention is by no means limited to this particular design of the locking device, and the locking device can be any suitable alternative design (e.g., a jaw type for clamping the surface of attachment 6 against handle 2 or other corresponding surfaces).

[0059] Although the latch 22 is therefore intended to be received in the corresponding lock slots 23, 24 in a locking configuration of the locking device, the shape of the latch 22 is not particularly limited thereto. For example, as in the embodiment shown in the figures, the latch 22 may take the form of a rigid rod (or “pin”) with a circular cross-section, which extends along a longitudinal axis and is intended to translate, i.e., slide, along this longitudinal axis between at least one position where at least a portion of the rod is inside the lock slots 23, 24 (locking configuration of the locking device) and a position where the rod is completely outside the lock slots 23, 24 (unlocking configuration of the locking device).

[0060] In the case where at least one of the first and second angular configurations of Annex 6 corresponds to a unique predetermined angular orientation of Annex 6 relative to the handle 2 (in which it is desired to lock Annex 6), the locking groove 23 is advantageously shaped to accommodate the bolt 22 securely therein. In the locking configuration of the locking device, the bolt 22 is thus captured within the locking groove 23 without significant play in the rotational direction of Annex 6 relative to the handle 2. However, if the periphery of the locking groove 23 is not necessarily closed, then the locking groove 23 has at least a peripheral portion forming a stop for the bolt 22 in each of the two directions of rotation of Annex 6. Obviously, it is conceivable that the locking device includes multiple pairs of bolts and corresponding locking grooves. In this case, the locking device will be advantageously configured such that each pair of bolts and locking grooves engages simultaneously with the other pairs of bolts and locking grooves. Furthermore, if each of the first and second angular configurations of Annex 6 corresponds to a unique predetermined angular orientation of Annex 6 relative to the handle 2 (in which it is desired to lock Annex 6), then the locking device may advantageously include at least one bolt 22 and two separate corresponding locking grooves 23. As described above, depending on whether Annex 6 is in a first angle configuration or a second angle configuration (in which Annex 6 should be locked), each of these locking slots 23 is shaped to alternately accommodate the locking tongue 22 therein.

[0061] In at least one of the first and second angular configurations in Annex 6, where Annex 6 is allowed to have a variable angular orientation relative to the handle 2 within a predetermined angular range—and where it is desirable to lock Annex 6 in said angular orientation—the locking groove 24 advantageously forms an angular slot 24, i.e., an arc-shaped opening (or slot), such as... Figure 8As shown. The length of the corner groove 24 thus defines the predetermined angle range, and the corner groove 24 is shaped to accommodate the latch 22 within it between two opposing ends 25, 26 forming a stop. Once the latch 22 is accommodated in the corner groove 24 in a locking configuration of the locking device, the relative movement of the latch 22 and the corner groove 24 is restricted by the opposing ends 25, 26 of the corner groove 24 (and thus the pivoting of the accessory 6 relative to the handle 2). According to one variation, the latch 22 is configured to directly abut against the ends 25, 26 of the corner groove 24. According to another variation (which will be described in more detail below in conjunction with the embodiments shown in the accompanying drawings), the latch 22 is configured to be accommodated in a locking configuration of the locking device within an intermediate member 27 movably mounted within the corner groove 24. The latch 22 can then indirectly engage with the ends 25, 26 of the corner groove 24 via the respective opposing ends 28, 29 of the movable intermediate member 27. Assuming that device 1 is designed such that each of the first and second angular configurations of accessory 6 allows for a variable (the degree of variation need not be the same for each angular configuration) angular orientation of accessory 6 relative to handle 2 within a predetermined angular range—and that accessory 6 is expected to be locked in said angular orientation—the locking device may advantageously include at least one latch 22 and two separate corresponding corner slots 24. As described above, each of these corner slots 24 will be shaped to alternately accommodate the latch 22, depending on whether accessory 6 is in the first angular configuration in which it should be locked or the second angular configuration.

[0062] According to a variation of an embodiment exemplarily illustrated in the accompanying drawings, the locking device is advantageously configured to (alternatingly) ensure that the accessory 6 is locked relative to the handle 2 in the first angular configuration when the accessory 6 is in the first angular configuration, and correspondingly locked in the second angular configuration when the accessory 6 is in the second angular configuration. According to this variation, the locking device includes a single latch 22, with a first locking groove 23 therein intended to be received to lock the accessory in the first angular configuration, and a second locking groove 24 (independent of the first locking groove 23) therein intended to correspondingly receive the latch 22 to lock the accessory 6 in the second angular configuration. This variation allows for a particularly simple design of the locking device of the hair styling device 1, because the same latch 22 makes it possible to alternately lock the accessory 6 in each of the first and second angular configurations. In the embodiment illustrated by way of example in the accompanying drawings, as described above, the single latch 22 of the locking device is formed by a rigid rod 22 (or "pin") of a circular cross-section. The lever 22 advantageously extends along a longitudinal axis, along which it translates (i.e., slides) when the locking device changes from a locking to an unlocking configuration, and vice versa. The longitudinal extension axis of the lever 22 is advantageously oriented substantially parallel to the second axis of rotation B-B' of the attachment 6 relative to the handle 2. In this example, the second axis of rotation B-B' coincides with or is at least parallel to the first longitudinal extension axis A-A' of the handle 2, therefore the longitudinal extension axis of the lever 22 is also advantageously substantially parallel to the first axis A-A'. Figure 6 , 7 (9 and 10).

[0063] More specifically, in the embodiment shown by way of example in the accompanying drawings, the first angular configuration (“hair dryer” mode) advantageously corresponds to a single predetermined angular orientation of the accessory 6 relative to the handle 2, while the second angular configuration (“blower brush” mode) advantageously allows for a variable angular orientation of the accessory 6 relative to the handle 2 within a predetermined angular range. The first locking groove 23 of the locking device is advantageously shaped to tightly accommodate a single locking tongue 22 therein to lock the accessory 6 in the first angular configuration. Figures 5 to 7 In this case, the first locking groove 23 is formed by a first cylindrical hole 23 with a circular cross-section, the first cylindrical hole being advantageously disposed in a half-shell 18 of the outer casing 18, the half-shell 18 having a second surface 16. Figure 5 and 8Advantageously, to limit the risk of the latch 22 being sheared under the forced rotational force along the second axis B-B' of Annex 6, the first cylindrical hole 23 forming the first locking groove 23 is through-hole, and the latch 22 is sized such that when the latch 22 is tightly received in the first locking groove in the locking configuration of the locking device, the distal portion 30 of the latch 22 extends beyond the first locking groove 23. The annular peripheral lip 19 of the internal deflector 14 is advantageously provided with a first aperture 31, formed in the lower surface of the annular peripheral lip 19 facing the through-hole first locking groove 23, and for tightly receiving the distal portion 30 of the latch 22 therein in the locking configuration of the locking device, such as partially in… Figure 6 and 7 As shown in the image.

[0064] The second locking groove 24 of the locking device advantageously forms a corner groove 24 (or an arc-shaped slot), the length of which defines the predetermined angle range, and, according to the explanation provided above, the corner groove is shaped to accommodate a single latch 22 between the two opposite ends 25, 26 of the corner groove 24 forming the stop. As described above, in the example shown in the figures, the latch 22 is not configured to directly abut against the ends 25, 26 of the corner groove 24 so as to prevent the accessory 6 from leaving the second angle configuration when the locking device is in the locked configuration. In fact, as in Figure 5 and 8 More specifically, attachment 6 includes an intermediate member 27 movably mounted within the corner slot 24. The intermediate member 27 is mechanically connected to attachment 6 by two traction springs 32, 33, each end of which abuts against the surface of a half-shell 18A of the housing 18 with the first face 15 of attachment 6, and the other end of which is connected to the intermediate member 27. Thus, the springs 32, 33 operate relative to each other, allowing the intermediate member 27 to oscillate within the corner slot 24 between a first extreme position (not shown) and a second extreme position (not shown), in which one end 28 of the intermediate member abuts against one of the ends 25 of the corner slot 24, and in the second extreme position, the opposite end 29 of the intermediate member 27 abuts against the other end 26 of the corner slot 24. The intermediate member 24 is provided with a second hole 34 advantageously equidistant from its ends 28, 29, the second hole 34 being shaped to tightly accommodate the locking tongue 22 therein, thereby locking attachment 6 in the second angle configuration. Figure 8 and 10 Therefore, attachment 6 is rotated a certain degree along the second axis BB′. In this case, the springs 32 and 33 are advantageously calibrated to automatically return the intermediate piece 27 to the intermediate position within the corner slot 24. Figure 5 and 8The springs 32 and 33 thus advantageously allow the defined known angular position, referred to as the static position, to be defined, in which the attachment 6 can automatically return when it is in the second angular configuration. Advantageously, to limit the risk of the latch 22 being sheared under the forced rotational force of the attachment 6 along the second axis B-B', the second cylindrical hole 34, provided with the intermediate member 27, is through-hole, and the latch 22 is sized such that when the latch 22 is tightly received in the second hole in the locking configuration of the locking device, the distal portion 30 of the latch 22 extends beyond the second hole 24. The annular peripheral lip 19 of the internal deflector 14 is advantageously provided with a second opening 35, which is located in the lower surface of the annular peripheral lip 19 facing the groove 24, and is used to tightly receive the distal portion 30 of the latch 22 therein in the locking configuration of the locking device, as Figure 9 and 10 As shown in the image.

[0065] Optionally, according to a variation not shown in the figures, the corner groove 24 forming the second locking groove 24 may advantageously be provided with a third opening, which is equidistantly positioned with the ends 25, 26 of the corner groove 24, and wherein the distal portion 30 of the latch 22 can be tightly accommodated when the attachment 6 is locked in the second angle configuration. Thus, by the engagement of the latch 22 with the third opening in the corner groove 24 (and, when the intermediate member 24 is implemented, with the second opening 34 of the intermediate member 24), the attachment 6 can be advantageously locked in the aforementioned intermediate static angle position. Therefore, if the user wishes, it is advantageously possible to prevent the attachment 6 from pivoting within the predetermined angle range when it is locked in the second angle configuration.

[0066] According to a preferred variant of the embodiment shown in the accompanying drawings, the control member 21 of the locking device is a manual mechanical control member 21, which is (directly or indirectly) connected to the latch 22, allowing the user to ensure the locking device is locked and / or unlocked on the accessory 6 by direct manual action on the control member 21. Therefore, the manual mechanical control member 21 is advantageously mounted to be movable at least between the locking position of the locking device in the locking configuration and the unlocking position of the locking device in the unlocking configuration under the action of the control member 21. Such a variant has the advantages of being relatively simple, inexpensive, and reliable in implementation. Alternatively, it can be an automatic control member that the user will indirectly act upon to control the locking and / or unlocking of the accessory 6 via the locking device. Such an automatic control member can then, for example, include an electromechanical relay connected on one side to the locking device and on the other side to a control and / or adjustment device 10 for manual control and / or adjustment of the operation of the hair styling device 1 by the user. Thus, when the user opens the hair styling device 1 by acting on the control and / or adjustment device 10, the automatic control member can, for example, automatically control the locking of the locking device in the angle configuration occupied by the accessory 6. The change in the angle structure of Annex 6 may require the user to stop the operation of the hair styling device 1 by acting on the control and / or adjustment device 10 again, thereby controlling the automatic unlocking of Annex 6.

[0067] However, the following description will refer more specifically to the preferred variant described above, wherein the control member 21 of the locking device is a manual mechanical control member 21.

[0068] Preferably, the manual mechanical control member 21 of the locking device is movably mounted on the handle 2, rather than on the attachment 6. In this way, the user can advantageously manipulate the manual mechanical control member 21 using his fingers gripping the handle 2 of the device 1, which helps to give the hair styling device 1 a particularly ergonomic character. Also preferably, the 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, the attachment 6 extends the handle 2 from that end; in the example shown in the figures, in this case, the extension begins at the second end 4 of the handle 2. This positioning of the manual mechanical control member 21, thus as close as possible to the interface between the rotating attachment 6 and the handle 2, particularly allows for a simpler, more reliable, and smaller design of the mechanical connection between the manual mechanical control member 21 and the locking device, especially by limiting the need for complex linkage mechanisms. Different kinematics of the manual mechanical control member 21 can be considered. According to a particularly simple variation of the embodiment shown in the figures, the manual mechanical control member 21 is advantageously mounted so as to be linearly translatable preferably along the first longitudinal extension axis A-A' of the handle 2. The manual mechanical control component 21 is thus advantageously formed by a slide button 36, which is slidably mounted in a groove 37 provided in the handle 2. According to another variation (not shown), the manual mechanical control component 21 can be mounted for rotatable movement, preferably rotating about a first longitudinal extension axis A-A' of the handle 2. According to yet another variation (not shown), the manual mechanical control component 21 can be mounted for translational and rotational movement, preferably along and around the first axis A-A', that is, along a helical connection. In both variations, the manual mechanical control component 21 can be formed by an annular ring mounted in a corresponding annular recess or groove provided in the handle 2 in a rotational or translational-rotational manner. According to a less advantageous variation (not shown), the manual mechanical control component 21 can be mounted for translational movement along an intersecting direction (e.g., an orthogonal direction) relative to the first longitudinal extension axis A-A' of the handle 2. In this case, the manual mechanical control component 21 can be formed by a button.

[0069] According to one variation (not shown), the manual mechanical control component 21 and the latch 22 (single or non-single) form a single integral part, which in particular simplifies the design of the hair styling device 1 and facilitates its assembly. According to another variation of the embodiment shown in the figures, the manual mechanical control component 21 and the latch 22 (single or non-single) can form separate components, which can then optionally be made of two different materials. The latch 22 and the control component 21 are then mechanically connected to each other, directly or indirectly. For example, the latch 22 can be assembled to the manual mechanical control component 21, for example, by screwing, bonding, press-fitting, or by overmolding. For example, the manual mechanical control component 21 can be made of plastic, in particular to reduce the overall weight of the control device, while the latch 22 can be made of metal, in particular to provide excellent mechanical strength, especially shear strength.

[0070] Advantageously, the hair styling device 1 includes a reset device configured to automatically reset the manual mechanical control member 21 to the locked position of the locking device when the manual mechanical control member 21 occupies the unlocked position of the locking device (and when the user stops any direct action on the manual mechanical control member 21). This ensures the advantageous unstable nature of the unlocking mechanism of the locking device as described above. Preferably, the reset device is an elastic reset device including at least one spring arranged to operate in a traction or compression manner to elastically reset the manual mechanical control member 21 to the locked position when it occupies the unlocked position. In the embodiment shown in the figures, the reset device is such an elastic reset device that, in this case, advantageously includes a pair of traction springs 38, 39 arranged between the surface of the handle 2 and the corresponding surface of the manual mechanical control member 21, which from Figure 7 and 10 The transparent representation of the manual mechanical control element 21 is visible. Clearly, other reset devices, whether elastic (leaf springs, etc.) or non-elastic (a pair of magnets, etc.), can be implemented alternatively to ensure this automatic reset function of the manual mechanical control element 21 in the locked position of the locking device.

[0071] Advantageously, the unstable nature of the unlocking mechanism of the locking device allows it to also function as an automatic addressing device for accessory 6 in the first and / or second angular configurations, in which accessory 6 can be locked by the locking device. This is because when the user rotates accessory 6 relative to handle 2 to position accessory 6 in the lockable angular configuration, the locking device automatically switches to the locking configuration, allowing the user to know that he has reached the required degree of rotation to effectively position accessory 6 in the desired angular configuration (by hearing noise from the locking device, such as the engagement noise of the latch 22 in the corresponding lock slots 23, 24, or simply due to the sudden cancellation of the force applied by the user to rotate accessory 6).

[0072] The device 1 may also advantageously include visual and / or tactile markings 40 designed to inform the user of the direction of rotation in which the attachment 6 should be pivoted relative to the handle 2, so as to position the attachment 6 in one or the other of the first and second angular configurations. Such marking device 40 may, for example, include a pair of opposing arrows 41 engraved, drawn, or otherwise implemented at the interface between the handle 2 and the attachment 6, particularly as... Figure 3 As illustrated in the example. Optionally or additionally, the visual and / or tactile markings 40 may be configured to inform the user of the angular position of the accessory 6 relative to the handle 2, the angular position precisely corresponding to reaching one or the other of the first and second angular configurations. As particularly in Figure 3 As shown, the mark 40 may therefore include, for example, a first mark 42 that protrudes from (or is engraved, drawn, or otherwise implemented on) the outer surface of the slide button 35 of the control member 21. The mark 40 may also include second and third marks 43, 44 that protrude from (or are engraved, drawn, or otherwise implemented on) the outer surface of the housing 18 of the accessory 21, corresponding to one or more locking slots 23, 24 or second holes 34, to which the locking bolt 22 of the locking device is received to ensure the locking of the accessory 6. The second and third marks 43, 44 are advantageously positioned to visually correspond to the first mark 42 when the accessory 6 is in a first angle configuration or a second angle configuration, respectively. Figure 3 ).

[0073] As described in detail above, the operation and use of the hair styling device 1 according to the invention are as follows. The accessory 6 of the device 1 initially occupies, for example, a first angular configuration relative to the handle 2 (corresponding to, for example, a "hair dryer" usage mode), in which the accessory 6 is preferably locked by the locking device of the device 1. The user then grasps the handle 2 of the device 1 with one hand, preparing to position the device 1 such that the first air outlet 12 of the accessory 6 faces toward their wet hair. The user then actuates the manual control and / or adjustment device 10 for controlling and / or adjusting the operation of the device 1, thereby blowing a forced airflow, preferably hot, through the first air outlet 12 of the accessory 6 toward their hair. Then, after the device 1 has been used for the desired time, for example until a certain degree of dryness or pre-dryness has been achieved in their hair, the user acts on the control member 21 of the locking device of the accessory 6 to unlock the accessory 6 via the locking device. For example, the user slides the slider 36 in the groove 37 of the manual mechanical control member 21 with the fingers (e.g., thumb) of the hand holding the handle 2, so that the slider 36 moves from its locked position (high position in the figure) to its unlocked position (low position). While keeping the accessory 6 unlocked in this way, the user manually rotates the accessory 6 relative to the handle 2 about the second axis of rotation B-B' by holding the handle 2 with one hand and the accessory 6 with the other hand until the accessory 6 is positioned in its second angle configuration (e.g., corresponding to the "blower brush" usage mode). The user can then stop any movement of the control member 21. Due to the advantageous unstable nature of the unlocking configuration of the locking device, the locking device then automatically switches to the locking configuration, thus locking the accessory 6 in the second angle configuration. The user can then advantageously use the device 1, for example by means of the hair-adhesive element 17, to comb and style his hair.
