Description

Improved hair cutting apparatus forming an oscillating blowing brush
Technical Field
The present invention relates to the general technical field of hair cutting devices, for example for domestic use, and more particularly to the field of portable hair cutting devices designed to blow an air flow to dry hair and/or to facilitate hair styling.
Background
In the field of hair-cutting devices, devices of the blow-brush type are known. These devices typically include a brush head connected to a gripping handle and having bristles disposed on all or a portion of its surface. The bristles are provided with blowing openings so that a stream of hot or cold air can be blown out through the brush head in the direction of the hair. Such air-blowing hairbrushes are intended to allow a certain degree of drying of the hair while achieving one or more hairstyling effects or hair styling.
While such known hair blow brushes are generally satisfactory, they are still not sufficiently sophisticated. In fact, the haircutting effect that the user considers to be able to obtain with these hairbrushes is not always easy to achieve in practice, especially for those users who do not have any particular knowledge of the hair. Such known hairbrushes also have a particularly complex design, which tends to affect, among other things, their reliability and ease of use. Furthermore, some known hairbrushes lack compactness, which makes them less ergonomic and less suitable for manipulation.
Furthermore, while such known hairstyling devices of the hairbrush-blow type aim to replace a plurality of separate devices by combining a brushing function with a hair drying function, they are not particularly well suited in practice to achieve satisfactory hair drying, in which case drying must be associated with haircutting or brushing. Known haircutting devices of the blow-brush type do not in themselves allow to effectively carry out a plurality of separate operations of hair drying, haircutting and styling, so that it appears that it is generally necessary to use complementary haircutting devices to satisfactorily carry out all the desired haircutting operations.
Disclosure of Invention
The object assigned to the invention is therefore to provide a novel portable hair cutting device which allows particularly satisfactory haircutting and hair styling results to be obtained easily, even for users who do not have a particular professional skill in the hair styling.
Another object of the present invention is to provide a novel portable hair cutting device which is particularly practical, intuitive and simple to use, even for users who do not have a particular expertise in the hair styling.
Another object of the present invention is to provide a novel portable hair cutting device having a particularly simple and reliable design.
Another object of the present invention is to provide a novel portable hair cutting device which is particularly compact.
Another object of the present invention is to provide a novel portable hair cutting device which allows the user to easily and efficiently carry out a variety of separate operations without the use of an external complementary hair cutting device.
Another object of the present invention is to provide a novel portable hair cutting device which allows particularly effective hair drying and styling to be obtained under comfortable conditions of use.
The object assigned to the invention is achieved by means of a portable hair cutting device comprising: a blower module for generating an air flow, a manually graspable handle and an accessory connected to the handle, the accessory including a hair mechanical engagement main element and at least one of first and second air outlets spaced apart from each other and positioned on either side of the hair mechanical engagement main element, the apparatus including an air distribution duct immovably mounted with respect to the handle and extending from an end of the handle, the air distribution duct including two air distribution outlets spaced apart from each other and spaced apart to distribute the air flow generated by the blower module in different average directions, the accessory being rotationally mounted with respect to the handle along an axis of rotation to occupy at least a first angular configuration permitting a variable angular orientation of the accessory within a predetermined angular range with respect to the handle, and in the first angular configuration the accessory is capable of moving between:
-a first angular position in which a first one of the air distribution outlets of the air distribution duct is in pneumatic communication with the first air outlet of the accessory; and
-a second angular position in which a second one of the air distribution outlets of the air distribution duct is in pneumatic communication with the second air outlet of the accessory.

Detailed Description
The hair-cutting apparatus 1 according to the invention is a portable hair-cutting apparatus designed to be grasped and manipulated by hand. It is a hair cutting device preferably intended to be used at home by users who do not have a specific professional skill in hair cutting, i.e. in drying, hair cutting, styling of hair. Preferably, the hair-cutting apparatus 1 is designed so that the user uses the apparatus 1 on his own, i.e. on his own hair. However, it is fully envisaged that the device 1 is designed to be used by a user on the hair of a third person without departing from the scope of the present invention.
The hair cutting device 1, of which a non-limiting embodiment is shown in the figures, comprises a manually gripped handle 2 (or grip), which handle 2 is intended to be manually gripped by a user for manipulating the hair cutting device 1. The handle 2 typically extends longitudinally between a first end 3 and an opposite second end 4, preferably along a (first) axis a-a'. The hair-cutting apparatus 1 also comprises a blower module 5, the blower module 5 being advantageously carried and designed to generate a (forced) air flow F, and an attachment 6, the attachment 6 being connected to the handle 2, and the air flow F generated by the blower module 5 being advantageously intended to be directed out of the hair-cutting apparatus 1 through the attachment 6 so as to be projectable towards the hair of the user. The hair-cutting apparatus 1 is provided with an air inlet 7 through which air inlet 7 ambient air can be sucked in by the blower module 5 to be blown out in the direction of the user's hair. The blower module 5 may advantageously comprise, in a known manner, a ventilator driven by an electric motor, the blower module 5 being advantageously arranged in the handle 2 or in the attachment 6. More preferably, however, the blower module 5 of the hair cutting device 1 is assembled on the handle 2 at the second end 4 of the handle 2, so that the blower module 5 advantageously extends the handle 2 beyond the second end 4 of the handle 2. Advantageously, the attachment 6 of the device 1 is itself connected to the handle at the first end 3 of the handle 2. Accordingly, the blower module 5 is preferably offset from the attachment 6 and the handle 2. Thus, the blower module 5 can be dimensioned in an economical manner so as to generate a large flow F of air and therefore without affecting the overall dimensions of the accessory 6 and of the handle 2. In addition, this arrangement of the blower module 5 advantageously allows a better balancing of the weight of the hair cutting device 1 by distributing the mass on both sides of the handle 2, which contributes to ergonomics and comfort of use of the hair cutting device 1. In the case where the blower module 5 is therefore arranged inside the handle 2 or assembled on the handle 2 at the second end 4 of the handle 2 as previously envisaged and shown in the figures, the haircutting device 1 can then advantageously comprise a guiding channel 8 (fig. 8), which guiding channel 8 is configured inside the handle 2 to guide the air flow F generated by the blower module 5 outside the handle 2 in the direction of the attachment 6.
Preferably, the hair cutting device 1 also comprises a heating element arranged to raise the temperature of the air flow F generated by the blower module 5. Mounted inside the hair-cutting apparatus 1, the heating element is arranged to be inserted in the air flow F generated by the blower module 5. In the embodiment shown in the figures, the heating element is advantageously positioned, as described above, inside said guide channel 8 of the air flow F arranged in the handle 2 (fig. 8). As is known, the heating element is typically an electric heating element, which operates according to the joule effect principle and comprises at least one electric heating resistor formed by an electric wire (not shown) wound around an insulating core 9. Alternatively, the heating element may be housed inside the accessory 6, but in particular not contributing to the compactness of the accessory 6.
Advantageously, the hair-cutting apparatus 1 comprises manual control and/or adjustment means 10, these manual control and/or adjustment means 10 being intended to be used by a user for manually controlling and/or adjusting the operation of the hair-cutting apparatus 1, in particular the operation of the blower module 5 and/or the heating element of the blower module 5. This is an adjustment device, for example of the toggle-switch type, push-button type and/or of the channel or roller-type, as in the example shown in figures 1 to 4, on which the user can act directly to electrically activate/deactivate the hair cutting apparatus 1 and to vary the speed of rotation of the ventilator of the blower module 5 and therefore the speed/flow of the air flow F blown by the accessory 6 and/or the heating temperature of the heating element. When the blower module 5 is assembled at the second end 4 of the handle 2, as in the example shown in fig. 1 to 4, such a manual control and/or adjustment device 10 may be positioned, for example, at the handle 2 or at the blower module 5, as is well known. Advantageously constituting a portable electrical apparatus, the hair cutting apparatus 1 is preferably arranged to be powered from mains electricity via a power cord 11. Alternatively, the hair cutting device 1 may be powered by an onboard energy source, such as a battery, which may then be housed in the handle 2.
The attachment 6 of the hair-cutting device 1 according to the invention comprises a hair mechanical engagement main element 12, which hair mechanical engagement main element 12 is capable of mechanically interacting with the hair of the user, in order to brush, cut and/or also comb the hair, in particular. The accessory 6 typically comprises a support 13, which support 13 is provided with a support surface 14 oriented towards the outside of the device 1, and said hair mechanical engagement main element 12 is optionally integrated in a removable manner with this support 13. For example, as in the embodiment shown in the figures, the mechanical-engagement main element 12 may comprise a plurality of rows or bars 12A, 12B, 12C of bristles (or brush pins) fixed on the support 13 and projecting from the support surface 14, preferably in a direction substantially perpendicular to the support surface 14. Alternatively, the mechanical engagement main element 12 may for example comprise bristles (or brush pins) integral with said support 13. The support surface 14 may be substantially flat or, as in the embodiment shown in the figures, convex towards the outside of the accessory 6.
The attachment 6 further comprises at least a first and a second (main) air outlet 15, 16, through which the air flow F can be blown by the attachment 6 towards the hair of the user, 15, 16. Said first and second air outlets 15, 16 are separate from each other and therefore not coincident and not adjacent and are positioned on either side of the hair mechanical engagement main element 12. As shown in the figures, said first and second air outlets 15, 16 are therefore advantageously positioned at the edge of the hair mechanical engagement main element 12 along the opposite side edges of the hair mechanical engagement main element 12.
As can be seen in particular from fig. 5 to 7, the presence of the first and second air outlets 15, 16 is permanent, i.e. non-replaceable. In other words, the first and second outlets 15, 16 are always present on either side of the hair mechanical engagement main element 12; the first and second outlets 15, 16 are not transitory.
According to a variant not shown in the figures, the accessory 6 may optionally comprise one or more hair mechanical engagement auxiliary elements. For example, the attachment 6 may comprise a first hair mechanical engagement aid element arranged such that said first air outlet 15 is positioned between said first hair mechanical engagement aid element and said hair mechanical engagement main element 12, and a second hair mechanical engagement aid element arranged such that said second air outlet 16 is positioned between said second hair mechanical engagement aid element and said hair mechanical engagement main element 12.
Preferably, the accessory 6 comprises a housing 17, the outer surface of which housing 17 advantageously defines the overall external shape and profile of the accessory 6. Said housing 17 is advantageously connected to the handle 2 at the first end 3 of the handle 2, so that said housing 17 (and therefore the accessory 6) advantageously extends said handle 2 directly beyond said first end 3 of the handle 2. The outer surface of the housing 17 therefore advantageously defines the overall external shape and profile of the end portion of the hair cutting device 1 that lengthens the handle 2 of said hair cutting device 1. As shown in the example of the figures, said housing 17 preferably comprises at least one first surface 18A, a portion of which 18A advantageously forms said support 13 of the hair mechanical engagement main element 12. Fixed to said support 13, the hair mechanically engaging main element 12 is therefore advantageously integral with the housing 17 and immovable with respect to this housing 17. Advantageously, the first surface 18A of the casing 17 carries the first and second air outlets 15, 16 of the accessory 6, so that said first and second air outlets 15, 16 are integral with the casing 17 and with the hair mechanical engagement main element 12, said first and second air outlets 15, 16 being non-movable with respect to the casing 17 and with the hair mechanical engagement main element 12. Thus, the housing 17 of the attachment, the hair mechanical engagement main element 12 and the first and second air outlets 15, 16 advantageously form a single motion sub-assembly of the hair clipping device 1.
Particularly advantageously, as in the embodiment shown in the figures, the first surface 18A of the housing 17 may be defined by all or part of the outer surface of the monolithic first housing element 17A. Thus, the support 13 of the hair mechanical engagement main element 12 and the first and second air outlets 15, 16 of the attachment 6 are advantageously integral with the first housing element 17A. Thereby, the design and manufacture of the accessory 6 is particularly simplified, for example, the first housing element 17A may easily be manufactured by injection molding of a plastic material.
Advantageously, as shown in the figures, said housing 17 (and more generally the appendix 6) extends longitudinally along the (second) average axis 8-8' between a lower end 19 and an opposite upper end 20, said housing 17 advantageously extending the handle 2 at this lower end 19 beyond the second end 4 of the handle 2. Said first and second air outlets 15, 16 are advantageously each defined by an elongated continuous opening, such as a slit, which advantageously extends longitudinally along one and the other, respectively, of the lateral edges of the hair mechanical engagement main element 12, in an average direction which is generally oriented along said extension axis 8-8' of the housing 17. Accordingly, other shapes and orientations of the first and second air outlets 15, 16 may alternatively be envisaged without exceeding the scope of the invention.
The hair-cutting apparatus 1 further comprises an air distribution duct 21 extending from the one end 3 of the handle 2, in this case, in the embodiment shown in the figures, from the first end 3 of the handle 2. Said air distribution duct 21 comprises two air distribution outlets 22, 23, the two air distribution outlets 22, 23 being separate and apart from each other and being arranged to distribute the air flow F generated by the blower module 5 outside the air distribution duct 21 in different average directions. As can be seen in fig. 5 to 7, the air distribution outlets 22, 23 are advantageously diametrically opposed. Preferably, said air distribution duct 21 comprises only two air distribution outlets 22, 23, the two air distribution outlets 22, 23 advantageously having substantially the same respective useful air passage section. In case the blower module 5 is arranged within the handle 2 or at the second end 3 of said handle 2, as in the embodiment shown in the figures, the air distribution duct 21 may advantageously comprise an air inlet 24, which air inlet 24 is connected to the guide channel 8 configured inside the handle 2 to collect the air flow generated by the blower module 5. The air distribution duct 21 therefore advantageously extends said air guide channel 8 beyond the first end 3 of the handle 3. Advantageously, the air distribution duct 21 and the air guide channel 8 in the handle 2 may be formed as an integral single piece, in order to further simplify the design and manufacture of the hair cutting device 1. For example, the air distribution conduit 21 may comprise a hollow tube 25 of cylindrical or also truncated-cone shape, the hollow tube 25 being open at one of its ends, as will be described later, the air distribution outlets 15, 16 being arranged through the wall of the tube 25, which wall is substantially airtight.
According to the invention, the accessory 6 is mounted rotating, pivoting with respect to the handle 2 along a (third) rotation axis C-C' to occupy at least a first angular configuration, i.e. a first predefined spatial arrangement of the accessory 6 with respect to the handle 2 rotation, which permits a variable angular orientation of the accessory 6 with respect to the handle 2 within a predetermined angular range. In other words, said first angular configuration corresponds to a plurality of different angular orientations (or positions) that the appendix 6 can occupy with respect to the handle 2 by rotating about the rotation axis C-C' within a predetermined and advantageously limited angular range. Thus, when the attachment 6 occupies this first angular configuration, called "variable angular orientation", the attachment 6 has a certain amplitude of rotation about the axis of rotation C-C' and is therefore able to pivot, oscillate, with respect to the handle 2, within said predetermined limited angular range, while blowing out the air flow outside the hair-cutting apparatus 1 through one and/or the other of said first and second air outlets 15, 16 of the attachment 6.
More specifically, the device 1 according to the invention is designed and configured so that when the appendage 6 occupies said first angular configuration, said appendage 6 is able to move in rotation between:
a first angular position (not shown) in which a first one of said air distribution outlets 22, 23 of the air distribution duct 21 is in pneumatic communication with the first air outlet 15 of the accessory 6; and
a second angular position (separated from said first angular position, as shown in figure 5) in which a second of said air distribution outlets 22, 23 of the air distribution duct 21 is in pneumatic communication with the second air outlet 16 of the accessory 6.
Thus, when the user uses the hair cutting device 1 and the attachment 6 of the hair cutting device 1 occupies said first angular configuration, referred to as "variable angular orientation", the interaction between the user's hair and the main hair mechanical engagement element 12 of the attachment 6 may cause pivoting of the attachment 6 with respect to the handle 2 along the rotation axis C-C ', under the effect of the tensile force applied to the main hair mechanical engagement element 12 by the user's hair. This has the effect that the air flow F is blown out selectively through one and/or the other of the first and second air outlets 15, 16 in the brushing or hair-cutting direction and thus in the direction in which the attachment 6 is pivoted about said axis of rotation C-C' in the direction of one or the other of said first and second angular positions. In this way, the air flow F is advantageously always as close as possible to the user's hair and blown out in an optimal direction, always as a function of the direction of movement of the device 1, without any specific action by the user, other than the action of brushing hair by means of the device 1. In this case, therefore, the air flow is always blown out in the direction from the root to the tip, which is particularly advantageous for certain hair styling operations or hair grooming operations. The hair-cutting device 1 according to the invention therefore allows particularly satisfactory haircutting and hair styling effects to be obtained easily, including for users who do not have specific knowledge in hair cutting.
Preferably, the first and second angular positions that can be adopted by the appendix 6 by rotation of the appendix 6 with respect to the handle 2 are opposite extreme positions of the first angular configuration, said predetermined angular range being comprised between 20 ° and 60 °, and preferably 50 °. This range of values contributes to impart to the device 1 a particularly ergonomic characteristic in use, by optimizing the amplitude of rotation, i.e. the travel stroke resulting from the tensile force exerted by the hair mechanical engagement main element 12, which is required to reach from one of said first and second angular positions to the other of said first and second angular positions.
Advantageously, said first and second air outlets 15, 16 of the attachment 6 are arranged to blow out the air flow F outside the device 1 in the direction of the hair mechanical engagement main element 12 and substantially tangentially to said supporting surface 14 of said hair mechanical engagement main element 12. In other words, as shown in particular in fig. 5 to 7, both said first and second air outlets 15, 16 are shaped and configured with respect to the support 13 of the main hair mechanical engagement element 12 to direct or orient the air flow F substantially tangentially to the support surface 14 of said support 13 of said main hair mechanical engagement element 12, in the direction of the main hair mechanical engagement element 12 positioned between said first and second air outlets 15, 16.
Thus, the average trajectory of the air flow F that can be blown out by one and/or the other of the first and second air outlets 15, 16 of the accessory 6 is advantageously secant (and not parallel) to the direction in which the bristles or brush needles of the hair mechanical engagement main element 12 protrude from the supporting surface 14 of the support 13 of this hair mechanical engagement main element 12. In this way, the air flow F can advantageously be as close as possible to the user's hair engaged by the mechanical hair-engaging main element 12, which allows further improving the haircutting, brushing or also hair straightening effect that can be obtained with the aid of the device.
Advantageously, the device 1 is designed and configured so that the pneumatic communication of the second air outlet 16 of the accessory 6 with the second air distribution outlet 23 of the air distribution duct 21 is inhibited when the accessory 6 occupies said first angular position. On the contrary, the device 1 is advantageously designed and configured so that the air communication of the first air outlet 15 of the accessory 6 with the first air distribution outlet 22 of the air distribution duct 21 is inhibited when the accessory 6 occupies said second angular position (fig. 5). Thus, all the air flow F generated by the blower module 5 can be blown alternately only through one or the other of said first and second distribution outlets 22, 23 of the air distribution duct 21, according to the first or second angular position occupied by the attachment 6 with respect to the handle 2, respectively. This characteristic particularly advantageously allows to simplify the design of the accessory 6 and to make the distribution of air to the first or second air outlet 15, 16 of the accessory 6 more reliable by limiting the pressure losses.
Advantageously, the device 1 is designed and configured so that, when the accessory 6 occupies said first angular configuration, the accessory 6 can occupy a third angular position shown in fig. 6, which is intermediate between said first and second angular positions and in which the first and second air outlets 22, 23 of the air distribution duct 21 are in pneumatic communication simultaneously with the first and second air outlets 15, 16 of the accessory 6. Thus, when the accessory 6 occupies said third angular position, the air flow generated by the blower module 5 can be blown out simultaneously through the first and second air outlets 15, 16 of the accessory 6. This allows to cause the air flow F to be expelled from both sides of the hair mechanical engagement main element 12, which is particularly advantageous when the user places the hairstyling device 1 in contact with a lock of hair for the first time at the start of a hair styling operation. In fact, the entire area of the lock of hair is treated before the user moves the device 1 and the hair exerts a traction on the mechanical hair-engaging main element 12, and therefore before the air flow F is blown out only through the first or second air distribution outlets 22, 23. Advantageously, said third angular position is an intermediate angular position of said first and second angular positions within said predetermined angular range. The amplitude of rotation of the appendix 6 between the first and third angular position is then equal to the amplitude of rotation of the appendix 6 between the second and third angular position (for example, an amplitude of 25 ° on either side of said third angular position).
More advantageously, the third angular position is a rest position, the appendix 6 comprising return means, preferably elastic, arranged to automatically return said appendix 6 to said third angular position when the appendix 6 occupies one or the other of said first and second angular positions. Thus, in the absence of forces exerted on the accessory 6 by the interaction between the user's hair and the hair mechanical engagement main element 12, the accessory 6 advantageously automatically returns itself to said third intermediate angular position, called rest position. Thus, the rotational force and the amplitude of rotation of the attachment 6, caused by the interaction between the hair of the user and the hair mechanical engagement main element 12 of the attachment 6, which is subsequently required to reach one or the other of said first and second angular positions, are advantageously reduced, which further improves the convenience and comfort of use of the device 1.
Said return means preferably comprise a pair of extension springs 26, 27, which extension springs 26, 27 are arranged to work against each other. Advantageously, arranged in a plane orthogonal to the rotation axis C-C' of the appendix 6, each of said springs 26, 27 is connected by one of its ends to the handle 2, or, as will be described in detail later, to an intermediate piece 28, which intermediate piece 28 can be at least temporarily immovable with respect to the handle 2. Each of said springs 26, 27 is connected by the other of its ends to the accessory 6 and, for example, to a respective bearing surface of the housing 17 of the accessory 6. If the implementation of such a pair of springs 26, 27 proves to be particularly effective and robust, to ensure such a function of automatically returning the accessory 6 in such a third intermediate angular rest position, other suitable return means, whether elastic (leaf springs, torsion springs, etc.) or non-elastic (magnet equivalent), can be alternatively implemented for this purpose. Advantageously, as in the embodiment shown in the figures, said resetting means are arranged outside the air flow circulating inside the device 1, so that on the one hand they do not cause interference with said air flow F and on the other hand they do not interfere with the good functioning of the resetting means, in particular when they have been heated by said heating element of the device 1.
Preferably, the device 1 according to the invention is designed and configured so that substantially all the air flow F generated by the blower module 5 and distributed by the air distribution duct 21 is blown out through the first air outlet 15 when the accessory 6 occupies said first angular position, through the second air outlet 16 of the accessory 6 when the accessory 6 occupies said second angular position, and, if necessary, through both said first and second air outlets 15, 16 of the accessory 6 when the accessory 6 occupies said third angular position, respectively.
However, optionally, the accessory 6 of the device 1 may comprise an auxiliary air outlet (not shown) separate from the first and second air outlets 15, 16 of the accessory 6 and arranged in pneumatic communication with the first air distribution outlet 22 of the air distribution duct 21 and/or the second air distribution outlet 23 of the air distribution duct 21, depending on whether the accessory occupies said first angular position, said second angular position or, optionally, also said third angular position. Thus, when the accessory 6 occupies said first angular position in said first angular configuration, the air flow generated by the blower module 5 can advantageously be blown preferentially mainly through the first air outlet 15 of the accessory 6, but at the same time can be blown at least partially through said auxiliary outlet. Conversely, when the appendix 6 occupies said second angular position in said first angular configuration, the air flow generated by the blower module 5 can advantageously be blown preferentially mainly through the second air outlet 15 of the appendix 6, but at the same time can be blown at least partially through said auxiliary outlet. Thus, especially if one or the other of said first and second air outlets 15, 16 of the accessory 6 is inadvertently blocked, for example by the presence of the hair of the user, the air flow F can still escape outside the device 1 through the auxiliary outlet of the accessory 6. This escape solution thus avoids overheating of the device 1, but also limits any risk of burning the user's hair or scalp. The presence of such an auxiliary air outlet may also be advantageous in the case where the useful cross section of one and/or other of said first and second air outlets 15, 16 appears undersized with respect to the very high flow rate of the air flow F that can be generated by the blower module 5 when the blower module 5 is operating at very high air flow rates. In practice, therefore, this limits, among other things, the risk of damaging the blower module 5 under the effect of the internal back pressure generated in the device 6, and of burning the user's hair (when it is heated by the heating element) due to the abnormal heating and acceleration of the air flow F caused by the limitation of the useful section of the first or second outlet 15, 16 by the user's hair, or by the "undersize" of said useful section. The term "auxiliary" is understood here as the fact that said auxiliary outlet does not constitute an air outlet through which, in normal use of the device 1, it is intended to preferentially blow the majority of the air flow, but instead constitutes a non-preferential outlet, called "bypass" or "safety", in the event that air cannot be suitably blown out through one or other of said main air outlets 15, 16 of the accessory 6. In other words, therefore, the apparatus 1 is advantageously designed and configured so that the air flow circulating inside said apparatus 1 is substantially and preferentially directed from the air distribution duct 21 towards one or the other of said air outlets 15, 16 of the accessory 6 (depending on the angular position occupied by the accessory 6 with respect to the handle 2), the auxiliary air outlet being configured as such to allow at least part of the air flow which cannot be expelled as expected through one or the other of said air outlets 15, 16 of the accessory 6 to escape. In this way, said auxiliary outlet is advantageously sized so that, in the absence of any unexpected specific limitation of the respective useful air passage cross-section of the first and second air outlets, at least 60% of the flow rate of the air flow F can be blown out through the first and/or second air outlet 15, 16 of the accessory 6, whatever the angular position occupied by the accessory 6 when the accessory 6 is in said first angular configuration.
Such auxiliary air outlet is preferably positioned between said first and second air outlets 15, 16 of the attachment 6 at the hair mechanical engagement main element 12. The auxiliary air outlet may typically be formed by one or more auxiliary holes arranged through the support 13 of the hair mechanical engagement main element 12 between the plurality of bristle rows or bars 12A, 12B, 12C of the hair mechanical engagement main element 12, such that when at least a portion of the air flow escapes through said auxiliary air outlet, the air is still blown in a controlled manner towards the hair of the user (and not for example towards the face of the user or towards the hand with which the user grips the handle 2 of the device 6). Optionally, such an auxiliary outlet may be equipped with a valve system configured so that at least a portion of the air flow F can be blown out through said auxiliary outlet only when a threshold pressure is reached, for example selected to represent a predetermined level of obstruction of one or other of said first and second air outlets 15, 16 of the accessory 6. It can also be provided in a variant that the auxiliary air outlet is formed by a third air outlet 33, which will be described below.
Advantageously, the air distribution duct 21 extends longitudinally from said first end 3 of the handle 2 along a (fourth) extension axis D-D 'coinciding with the rotation axis C-C' of the appendix 6 with respect to the handle 2. The attachment 6 can therefore advantageously be mounted rotatably with respect to the handle 2 about the air distribution duct 21, which contributes in particular to simplifying the design and operation of the device 1. Thus, as in the embodiment shown in the figures, the air distribution duct 21 can advantageously extend inside the casing 17 of the accessory 6, the respective axes of extension B-B ', D-D' of the casing 17 and of the air distribution duct 21 advantageously being parallel or coincident with each other. It is then advantageous to provide one or more ball bearing embodiments between the air distribution duct 21 and the casing 17 of the accessory 6, so as to facilitate the rotation of the casing 17 around said air distribution duct 21. Optionally, although disadvantageous in particular in terms of design, it is optionally conceivable for the axis of extension D-D ' of the air distribution duct 21 to be parallel to the axis of rotation C-C ' of the attachment 6 and to be offset to a greater or lesser extent from this axis of rotation C-C '. Advantageously, the axis of rotation C-C 'about which the attachment 6 is rotatably mounted with respect to the handle 2 coincides with the axis of extension A-A' of the handle 2, as in the embodiment shown in the accompanying drawings. However, the rotation axis C-C ' may alternatively be parallel to the extension axis A-A ' of the handle 2 and more or less offset with respect to the extension axis A-A '. The kinematics of the attachment 6 are therefore simple and reliable and allow intuitive manipulation of the hairdressing apparatus 1 by the user. Still alternatively, it is conceivable that the rotation axis C-C 'of the appendix 6 intersects the extension axis a-a' of the handle 2 at an angle, for example, comprised between 5 ° and 15 °. It is particularly advantageous that, as in the example shown in the figures, the axis of extension a-a ' of the handle 2 coincides with the axis of rotation C-C ' of the appendix 6 and with the axis of extension D-D ' of the air distribution duct 21. However, it is also possible to envisage, for example, that the axis of rotation C-C ' of the appendix 6 and the axis of extension D-D ' of the air distribution duct 21 coincide with each other while intersecting the axis of extension a-a ' of the handle 2 at an angle, for example, comprised between 5 ° and 15 °, or also, for example, substantially equal to 90 °.
As already mentioned above, the first and second air distribution outlets 22, 23 of the air distribution duct 21 of the hair cutting device 1 according to the invention are arranged to distribute the air flow F generated by the blower module 5 in different average directions, advantageously in opposite directions and therefore not in substantially parallel directions. Thus, the air flow F can be easily distributed in the direction of the first and second air outlets 15, 16 of the attachment 6 with a minimum of pressure losses, which allows to maintain a good speed and a good flow rate of the air flow F and, therefore, a higher efficiency of the hair cutting device 1. Advantageously, and in particular in the case where the rotation axis C-C ' of the accessory 6 coincides with the longitudinal extension axis D-D ' of the air distribution duct 21, said first and second distribution outlets 22, 23 are more particularly provided, in particular in terms of shape and arrangement, to distribute said air flow F along different average directions forming an angle comprised between 165 ° and 195 ° with said extension axis D-D ' of the air distribution duct 21.
In other words, the first and second distribution outlets 22, 23 are arranged such that:
when the appendage 6 occupies a first angular position, the first dispensing outlet 22 is able to blow out, by itself, an air flow in a first mean square direction;
when the appendage 6 occupies the second angular position, the second distribution outlet 23 is able to blow out the flow of air in a second mean square direction, on its own;
said first and second mean square directions are respectively inscribed in a plane secant along the extension axis D-D 'of the air distribution duct 21 so as to form an angle of between 165 ° and 195 ° with said extension axis D-D'.
In this way, said first and second distribution outlets 22, 23 are therefore advantageously positioned in a substantially diametrically opposite manner with respect to the extension axis D-D' of the air distribution duct 21. This configuration advantageously allows in particular to simplify the design of the device 1 and to optimize its pneumatic operation, while maintaining the limited dimensions of the accessory 6.
In the embodiment shown by way of example in the figures, and as can be seen in particular in fig. 8 and 10, the air distribution duct 21 comprises a hollow tube 25 (as envisaged above) of substantially truncated cone shape, the axis of rotation of this hollow tube 25 being advantageously formed by the axis of extension D-D' of the distribution duct 21. The axis of extension D-D 'of the dispensing duct 21 coincides here with the axis of extension a-a' of the handle 2. The respective extension axes a-a ', D-D ' of the dispensing duct 21 and of the handle 2 coincide themselves with the rotation axis C-C ' of the appendix 6, as preferably envisaged above. When the accessory 6 is connected to the handle 2, said distribution duct 21 is advantageously housed inside a casing 17 of the accessory 6, said casing 17 being rotatably mounted around a tube 25 of the air distribution duct 21 (fig. 10). The air distribution duct 21 advantageously extends the air guiding channel 8 arranged inside the handle 2 through the large bottom of the truncated cone shaped tube 25, where the air inlet 24 of the air distribution duct 21 is arranged. The useful passage section of the air flow F inside the duct 25 therefore decreases along the extension axis D-D' of the dispensing duct 21, away from the handle 2. The air distribution duct 21 advantageously comprises two single air distribution outlets 22, 23 of the same useful section, these air distribution outlets 22, 23 being arranged through a side wall 29 of the hollow tube 25, this side wall 29 being airtight. Each of said air distribution outlets 22, 23 takes the form of an oblong slot in this example, extending longitudinally in a plane carrying the extension axis D-D' of the distribution duct 21. In this example, said first and second air distribution outlets 22, 23 are arranged substantially diametrically opposite with respect to the extension axis D-D' of the distribution duct 21. The substantially truncated-cone shape of the duct 25 of the air distribution duct 21 is advantageously arranged to homogenize the profile of the air flow F circulating inside the duct 25 along the extension axis D-D' of the distribution duct 21 and escaping from the duct 25 through the air distribution outlets 22, 23. The air distribution duct 21 advantageously also comprises deflecting fins 30, these deflecting fins 30 being positioned at the air distribution outlets 22, 23 so as to distribute the air in a radial direction, i.e. advantageously orthogonal to the extension axis D-D' of the distribution duct 21, by these deflecting fins 30 and to homogenize the profile of the air flow D thus distributed. The attachment 6, in turn, advantageously comprises, in the embodiment illustrated by way of example in the accompanying drawings, a first and a second pull-through portion 31, 32, the first and second pull-through portions 31, 32 being arranged so as to ensure that the first and second air distribution outlets 22, 23 of the air distribution duct 21 are in pneumatic communication with the first and second air outlets 15, 16, respectively, of the attachment 6 when the attachment 6 occupies said first angular configuration with respect to the handle 2. As shown in particular in the examples in fig. 5 to 7, the first and second pull-through portions 31, 32 may advantageously be arranged through the first housing element 17 of the housing 17 of the accessory 6. Advantageously, as can be seen in particular in fig. 5 to 7, in the embodiment shown in the figures, the tight rotational cooperation of the air distribution duct 21 with the respective inner surface of the casing 17 of the accessory 6 allows to alternately inhibit the pneumatic communication of the second air outlet 16 of the accessory 6 with the second air distribution outlet 23 of the air distribution duct 21 and vice versa, the pneumatic communication of the first air outlet 15 of the accessory 6 with the first air distribution outlet 22 of the air distribution duct 21, depending on whether said first or said second angular position is occupied by the accessory (fig. 5).
According to an advantageous variant remaining in the embodiment shown in the accompanying drawings, the attachment 6 also comprises a third (main) air outlet 33, said third (main) air outlet 33 being separate from the first and second air outlets 15, 16 (and, if necessary, preferably, said auxiliary air outlet), and the attachment 6 is mounted in rotation with respect to the handle 2 along said rotation axis C-C' of the attachment 6 so as to occupy, instead of said first angular configuration described previously, a second angular configuration in which said attachment 6 is then able to blow out an air flow only through said third air outlet 33. Thus, said appendix 6 is advantageously mounted rotating, pivoting about a rotation axis C-C' with respect to the handle 2, to alternate between at least said first angular configuration (fig. 1, 2, 5, 6, 10 and 12), previously described, in which the air flow is blown by the appendix 6 through one and/or the other of the first and second air outlets 15, 16 of the appendix 6, and a second angular configuration (fig. 3, 4, 7 and 13), in which the air flow is blown by the appendix 6 only through said third air outlet 33. In other words, the attachment 6 is mounted in a pivotal connection with respect to the handle 2 so as to be rotatable with respect to the handle 2, and the hair cutting device 1 is advantageously designed and configured to allow the user to alternately select whether said attachment 6 blows an air flow through the first and/or second air outlet 15, 16 of the attachment 6 or through the third air outlet 33 of the attachment 6 by pivoting the attachment 6 with respect to the handle 2.
In this way, the hair cutting apparatus 1 is advantageously designed and configured such that:
when the accessory 6 adopts said first angular configuration, neither the first nor the second air distribution outlet 22, 23 of the air distribution duct 21 of the device 1 is in pneumatic communication with the third air outlet 33 of the accessory 6, but
When the accessory 6 adopts said second angular configuration, at least one of the first and second air distribution outlets 22, 23 of the air distribution duct 21 of the device 1 is in pneumatic communication with the third air outlet 33, and neither of said first and second air distribution outlets 22, 23 is in pneumatic communication with one and/or the other (if necessary, and/or the auxiliary air outlet) of said first and second air outlets 15, 16 of the accessory 6.
For example, in the embodiment shown in the figures, this characteristic is ensured by the close fit of the air distribution duct 21 with the corresponding inner surface of the housing 17 of the accessory 6 (fig. 5 to 7).
Thus, by rotating the attachment 6 relative to the handle 2, the user can advantageously pass from a "blow brush" mode of use, in which the attachment 6 occupies said first angular configuration and can move between said first and second angular positions to blow air through one and/or the other of said first and second air outlets 15, 16, to another mode of use, which corresponds to the attachment 6 occupying said second angular configuration, and in which the air flow is then blown mainly through the third air outlet 33 of the attachment 6.
Advantageously, as shown by way of example in the accompanying figures, said housing 17 of the accessory 6 comprises a second surface 188, this second surface 188 carrying said third air outlet 33. Advantageously, the first and second surfaces 18A, 188 of the housing 17 are then positioned on either side of the axis C-C 'of longitudinal extension of the housing 17 of the accessory 6 and of the axis C-C' of rotation of the accessory 6 with respect to the handle 2. The attachment 6 also preferably comprises a third pull-through portion 34, which third pull-through portion 34 is arranged to ensure pneumatic communication between at least one of said first and second air distribution outlets 22, 23 of the air distribution conduit 21 and said third air outlet 33 of the attachment 6 when the attachment 6 is in said second angular configuration. Advantageously, the useful section of said third air outlet 34 of the attachment 6 can be defined by the profile of the outlet end 35 of the third pull-through portion 34, as shown in fig. 5 to 7. Advantageously, the housing 17 of the accessory 6 comprises a second housing element 17B, integral or not, which second housing element 17B is integral (for example by screwing or by snap fastening) with the first housing element 17A described previously and is not movable with respect to this first housing element 17A. Then, as in the embodiment shown in the figures, the second housing element 17B may comprise the third pull-through portion 34 or be immovably integrated with the second housing element 17B by any suitable means.
As shown in particular in fig. 4, said third air outlet 33 may advantageously have an elongated substantially rectangular opening (the air flow being discharged in the form of an air knife). Alternatively, said third air outlet 33 may for example have a substantially circular opening (the air flow exits in a substantially cylindrical or truncated-cone shape). Thus, when the attachment 6 occupies said second angular configuration with respect to the handle 2, the hair cutting device 1 can be advantageously used for drying the hair of the user ("hairdryer" mode). Advantageously, the second angular configuration then corresponds to a single predetermined angular orientation (or position) of the appendix 6 with respect to the handle 2 (and therefore not variable within a predetermined angular range). Thus, when the appendage 6 is not oriented according to such a single predetermined angular orientation or position with respect to the rotation axis C-C', the air flow is not advantageously blown by the appendage 6 through said third air outlet 33. Thus, the attachment 6 is advantageously able to blow out an air flow in a predetermined single average direction through the third air outlet 33. Of course, the third air outlet 33 of the attachment may have one or more openings of a general shape different from that described above, and the attachment 6 may be more generally arranged to be used for other purposes than drying hair when it occupies this second angular configuration relative to the handle 2. Furthermore, the device 1 may alternatively be configured such that said second angular configuration permits a variable (and no longer unique) angular orientation of the accessory 6 relative to the handle 2 within a predetermined angular range.
The hair-cutting apparatus 1 thus advantageously constitutes a multifunctional apparatus that combines a "blowing brush" mode of operation/use and at least one further alternative mode of operation/use (so-called "two-in-one" hair-cutting apparatus), as already described in connection with the embodiment shown in the figures, in particular according to the selected shape of the third air outlet 33, preferably in the "blower" mode.
In order to maintain simplicity of design and manufacture, the device 1 is advantageously designed and configured so that the transfer of the accessory 6 from one to the other of said first and second angular configurations can be effected manually by the user. In particular, the housing 17 of the attachment 6 is advantageously shaped so as to permit easy manual gripping by the user, so that the user, by gripping the handle 2 of the hair-cutting apparatus 1 with one hand and gripping said housing 17 with the other hand, can apply by hand a pivoting movement of said handle 6 with respect to the handle 2 about the rotation axis C-C' directly to said housing 17 (and therefore to the attachment 6) to ensure the transition of the attachment 6 from one to the other of said first and second angular configurations.
Advantageously, as in the embodiment shown in the figures, the hair cutting device 1 is designed and configured to permit the transition of the attachment 6 from one to the other of said first and second angular configurations by rotating the attachment 6 by an angle equal to 90 ° about the rotation axis C-C'. However, the value of this angle is not limited in practice, and the passage of the appendage 6 from the first angular configuration to the second angular configuration may for example alternatively correspond to a rotation of the appendage 6 about the rotation axis C-C' by an angle equal to 180 °.
In the preferred case where the hair-cutting apparatus 1 is advantageously designed so that the attachment 6 can alternately occupy said first and second angular configurations described above, the hair-cutting apparatus 1 preferably comprises locking means for locking the attachment 6 with respect to the handle 2, which are arranged to inhibit the attachment 6 from leaving said first angular configuration by rotating about the rotation axis C-C' when said attachment 6 occupies said first angular configuration (the "blowing-brush" mode). Thus, said locking means of course do not inhibit the rotation of the accessory 6 about the rotation axis C-C' according to said predetermined angular range. Still more preferably, as in the embodiment shown in the accompanying drawings, said locking means are also arranged to inhibit conversely the accessory 6 from leaving said second angular configuration by rotating about the rotation axis C-C', when said accessory 6 accordingly occupies said second angular configuration ("blower" mode). The hair cutting device 1 then advantageously comprises a control member 36 for allowing a user of the hair cutting device 1 to control the locking and/or unlocking of the attachment 6 by means of said locking means.
Thus, the locking device is advantageously designed to be reversibly shifted between:
a locking configuration in which said locking means mechanically forbid any possibility of driving the accessory 6 in rotation along the rotation axis C-C' with respect to the handle 2, to take the accessory 6 out of said first angular configuration in which it is locked (and preferably vice versa in said second angular configuration); and
an unlocking configuration, in which said locking means in turn permit the rotation of the accessory 6 with respect to the handle 2 along said rotation axis C-C', so as to mechanically enable the accessory 6 to leave said first angular configuration in which it is situated (and preferably vice versa), in order to advantageously bring it into the second angular configuration in which it can alternately occupy (and preferably vice versa).
The transition from the locked configuration to the unlocked configuration and vice versa requires a positive action by the user on the control member 36 for controlling the locking/unlocking of the accessory 6. 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 therefore not be able to leave the angular configuration in which it is located without prior positive action on the control member 36 by the user 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 is not possible. Advantageously, the control member is functionally independent of the handle 2 and the appendix 6. In other words, although the control member 36 may 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 later, the handle 2 and/or the attachment 6 do not constitute said control member 36 as such. In particular, the unlocking of the appendix 6 cannot be controlled by the user by exerting a force on the entire handle 2 and/or appendix 6.
The possibility of locking the angular configuration of the attachment 6 in the "blowing brush" mode (first angular configuration), thus preferably provided by the device 1, particularly allows to avoid that, when the user brushes his hair by means of the device 1, the interaction between the user's hair and the hair mechanical engagement elements 12 of the attachment 6 causes sufficient force to pivot the attachment 6 about the rotation axis C-C' and thus to move the attachment 6 away from its first angular configuration "blowing brush". On the contrary, the additional possibility of locking the angular configuration of the accessory, preferably provided by the device 1, for example in the "blower" mode (second angular configuration), particularly allows advantageously avoiding that, when the user dries his hair by means of the device 1 by performing an alternate rotary motion with the wrist of the hand holding the handle 2 of the device 1, the accessory 6 enters the rotating state due to inertia and accidentally leaves its first angular configuration "blower". The implementation of such locking means for locking the angular configuration occupied by the attachment 6 with respect to the handle 2 therefore advantageously allows the user to avoid a certain number of inconveniences in actual use and brings about a great reliability in the use of the hairdressing apparatus 1. Furthermore, said locking means help to ensure a particularly safe working of the hair-cutting apparatus 1, since they allow in particular to avoid the accidental projection of the hot air flow in an unexpected direction and for example in the direction of the eyes of the user, due to an undesired rotation of the attachment 6, which could cause the attachment 6 to suddenly change angular configuration. The risk of overheating and damage to the device 1, which may occur due to undesired rotation of the attachment 6, can also be limited by means of the locking means, which would bring the attachment 6 in an angular position outside said first and second angular configuration, and which, as a result, would excessively strongly limit, or even completely inhibit, the projection of the air flow generated by the blower module 5 outside the hairdressing device 1. The hair-cutting apparatus 1 can therefore be advantageously used according to a plurality of different modes of use (multifunction apparatus), which is not only particularly simple and practical to use, since it is sufficient for the user to modify the configuration/orientation of the attachment 6 with respect to the handle in order to pass from one mode of use to another, but which is also particularly reliable and safe since the hair-cutting apparatus 1 does not leave the angular configuration it occupies during operation in the event of user's wishes.
Alternatively, in the case where the hairstyling apparatus 1 does not comprise such locking means of the accessory 6, the apparatus 1 may then advantageously comprise limiting means for limiting the rotation of the accessory 6 with respect to the handle 2, so as to limit, but not completely inhibit, the ability of the accessory 6 to leave its angular configuration occupied. The limiting means may for example be formed by a pair of magnets, a protrusion or the like. Advantageously, said limiting means can also function as indexing means, which allows the user to know that the appendix 6 is indeed in the relative 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 angular configuration. For example, the hair cutting device 1 may comprise locking means as envisaged above for inhibiting the accessory 6 from leaving said first angular configuration (the "blowing brush" mode) when said accessory 6 occupies the first angular configuration, and limiting means according to the preceding description for limiting, but not completely inhibiting, the ability of the accessory 6 to leave said second angular configuration (the "blower" mode, for example) when said accessory 6 occupies the second angular configuration.
Advantageously, the unlocked configuration of the locking device is an unstable configuration such that the locking device tends to naturally return from itself towards its locked configuration when it is in the unlocked configuration. The safety of the hair-cutting apparatus 1 is thus improved, since the control member 21 tends to naturally resume its locking configuration and therefore to lock the appendix 6 (provided that the appendix 6 then occupies one of said first and second angular configurations that can be locked) in the absence of the user taking a positive action on the control member 21 of the locking device.
In order to allow the locking means to lock the accessory 6 in the first angular configuration (the "blowing brush" mode), while at the same time permitting the accessory 6 to be rotationally shifted within said predetermined angular range between said first and second angular positions described previously, said locking means may advantageously comprise a latch 37 and an angular groove 38, i.e. an opening (or slot) in the form of a circular arc, said angular groove 38 being shaped so as to receive said latch 37 therein between two opposite ends 39, 40 of said angular groove 38 forming stops, as can be seen in fig. 12 and 13. The length of the angular slot 38 is advantageously selected so as to define, limit the predetermined angular range. Thus, once the latch 37 is housed in said angular groove 38 in the locking configuration of the locking device, the relative movement of the latch 37 and the angular groove 38 (and therefore the pivoting of the accessory 6 with respect to the handle 2) is limited by the opposite ends 39, 40 of the angular groove 38. In the unlocked configuration of the locking device, the latch 37 can no longer cooperate with the angular slot 38, so that it no longer creates any obstacle to the rotation of the accessory 6, and the accessory 6 can then leave the first angular configuration. Advantageously, the angular slot 38 is integral with the accessory 6, while the latch 37 is integral with the handle 2, which allows in particular to simplify the design of the accessory 6. As shown in the figures, the latch 37 may advantageously take the form of a rigid rod (or "pin") with a circular section, which extends along a longitudinal axis, said rod being arranged to move translationally and slidingly along the longitudinal axis between at least one position in which at least a portion of the rod is positioned inside the angular groove 38 (locking configuration) and a position in which the rod is conversely positioned completely outside said angular groove 38 (unlocking configuration).
In the embodiment shown in the figures, the appendix 6 advantageously comprises an intermediate piece 28 as previously described, the intermediate piece 28 being mounted slidably and movably in said angular slot 38. Said intermediate piece 28 is mechanically connected to the accessory 6 by means of two extension springs 26, 27, the automatic return means for automatically returning the accessory 6 in said third intermediate angular position advantageously comprising the two extension springs 26, 27 according to the description provided previously. As shown in fig. 12 and 13, said springs 26, 27 have respective ends which abut against a first internal bearing surface of the casing 17 of the accessory 6, and have the other respective ends integrally connected to said intermediate piece 28. The springs 26, 27 thus work against each other, so that the intermediate piece 28 can oscillate inside the angular groove 38 between a first extreme position, in which one end of the intermediate piece 28 abuts against one of the ends 39, 40 of the angular groove 38, and a second extreme position, in which the opposite end of the intermediate piece 28 abuts against the other of the ends 39, 40 of the angular groove 38. The intermediate piece 28 is also preferably provided with a first hole 41, equidistant from the end of the intermediate piece 28, which first hole 41 is shaped so as to tightly receive the latch 37 therein to lock the accessory 6 in said first angular configuration (figure 12), while thus giving the accessory 6 a certain amplitude of rotation along said rotation axis C-C'.
Said first and second extreme positions of intermediate member 28 within angular slot 38 advantageously correspond to said first and second angular positions, respectively, between which appendix 6 can be moved when it occupies said first angular configuration with respect to handle 2. Thus, when appendix 6 is locked in the first angular configuration by cooperation of latch 37 and angular slot 38, said first and second angular positions advantageously constitute extreme stop positions, which define the amplitude of free rotation, oscillation, of appendix 6 about axis C-C' when appendix 6 occupies said first angular configuration.
Optionally, the angular slot 38 may advantageously be provided with a second hole (not shown) positioned, for example, equidistant from the ends 39, 40 of the angular slot 38 and in which the distal portion of the latch 37 can be closely received when the accessory 6 is locked in the first angular configuration. In this way, by making the latch 37 cooperate with said second hole provided in the angular slot 38 (and with said first hole of the intermediate piece 28 when the intermediate piece 28 is implemented), the accessory 6 can be advantageously locked in said third angular position already mentioned above. Thus, it is advantageously possible to inhibit the pivoting of the accessory 6 within said predetermined angular range when the accessory 6 is locked in said first angular configuration, if desired by the user.
It should be noted that in the case where the accessory 6 is not arranged to occupy such a third intermediate rest position when it is in the first configuration (the "blowing brush" mode), the intermediate piece 28 may optionally be omitted and the latch 37 may be arranged to abut directly (and no longer indirectly) against the ends 39, 40 of the angular slot 38.
In the embodiment shown by way of example in the figures, the second angular configuration (for example "blower" mode) advantageously corresponds to a single predetermined angular orientation of the appendix 6 with respect to the handle 2. Thus, in order that said locking means may also advantageously mutually inhibit the accessory 6 from leaving said second angular configuration when said accessory 6 occupies said second angular configuration, said locking means may advantageously further comprise, as envisaged above, a third hole 42, which third hole 42 is arranged in the housing 17 of the accessory 6 and which third hole 42 is shaped so as to tightly receive therein the latch 37 to lock the accessory 6 in said second angular configuration (fig. 13). In the locking configuration of the locking device, the latch 37 is then captured in the third aperture 42 without significant play in the direction of rotation of the attachment 6 relative to the handle 2.
Given that the device 1 is designed such that each of said first and second angular configurations of the appendix 6 (and no longer just the first) permits an angular orientation of the appendix 6 with respect to the handle 2 that is variable within a predetermined angular range (not necessarily to the same extent for each of the angular configurations) and within which it is desired that the appendix 6 can be locked, the locking means may advantageously comprise at least one latch and two separate respective angular grooves. Each of these angular slots is shaped to receive said latches 37 alternately 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, according to what has been described above.
Preferably, as in the embodiment shown in the figures, the control member 36 of the locking device is a manual-mechanical control member 36, which manual-mechanical control member 36 is connected (directly or not) to the latch 37, so that the user can ensure locking and/or unlocking of the accessory 6 by the locking device by direct manual action on the control member 36. Thus, said manual-mechanical control member 36 is advantageously mounted movably under the action of said control member 36, at least between a locking position, in which the locking means occupy said locking configuration, and an unlocking position, in which the locking means occupy said unlocking configuration. This variant has the advantage of being relatively simple to implement, inexpensive and reliable. Alternatively, it may be an automatic control member, on which the user acts indirectly to control the locking and/or unlocking of the accessory 6 by means of a locking device. 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 a manual control and/or adjustment means 10 for manual control and/or adjustment of the working of the hair cutting device 1 by the user. Thus, when the user activates the hair cutting apparatus 1 by acting on the control and/or adjustment device 10, the automatic control means can automatically control, for example, the locking of the locking device in the angular configuration occupied by the attachment 6. A change in the angular configuration of the attachment 6 may require the user to stop the operation of the hair cutting apparatus 1 by acting again on the control and/or adjustment device 10 in order to control the automatic unlocking of the attachment 6.
Preferably, the manual mechanical control member 36 of the locking device is movably mounted on the handle 2, not on the attachment 6. In this way, the user can advantageously manipulate the manual mechanical control member 36 by means of the fingers with which the user grips the handle 2 of the device 1, which contributes to giving the hair cutting device 1 particularly ergonomic features. It is also preferred that said manual-mechanical control member 36 is mounted at an end of the handle 2 from which the attachment 6 extends the handle 2, in which case said manual-mechanical control member 36 is mounted at said second end 4 of the handle 2, in the example shown in the figures. Such a positioning of the manual-mechanical control member 36, therefore 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 36 and the locking device, while in particular limiting the need to use complex linkage arrangements. Different kinematics of the manual mechanical control member 36 are envisaged. According to a particularly simple variant remaining in the embodiment shown in the figures, the manual mechanical control member 36 is advantageously mounted, preferably linearly translationally movable, along a longitudinal extension axis a-a' of the handle 2. The manual mechanical control member 36 is then advantageously formed by a slider 36, which slider 36 is slidably mounted in a guide slot 43 arranged in the handle 2. Alternatively, the manual mechanical control member 36 may preferably be mounted rotatably movable about a longitudinally extending axis A-A' of the handle 2. Still alternatively, the manual mechanical control member 36 may preferably be mounted translatably and rotationally movable along and about the longitudinally extending axis a-a' of the handle 2, thus that is to say according to a screw connection. In both alternatives, the manual mechanical control member 36 may be formed by an annular ring mounted in a rotary or translatory rotary manner within a corresponding annular groove or recess provided in the handle 2. According to another less advantageous alternative, the manual mechanical control member 36 may be mounted translationally movable in a direction secant (and for example orthogonal) to the longitudinal extension axis a-a' of the handle 2. In this case, the manual mechanical control member 36 may be formed by a button.
Advantageously, the hair cutting device 1 comprises resetting means arranged to automatically reset said manual-mechanical control member 36 to said locking position of the locking means when the manual-mechanical control member 36 occupies said unlocking position of the locking means (and the user stops any direct action on the manual-mechanical control member 36). This therefore ensures the advantageously unstable nature of the unlocking configuration of the locking device as previously envisaged. Preferably, said return means are elastic return means comprising at least one spring, arranged to work in tension or compression, so as to elastically return the manual-mechanical control member 36 to the locking position when the manual-mechanical control member 36 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 extension springs 44, 45, which pair of extension springs 44, 45 is arranged between a surface of the handle 2 and a corresponding surface of the control member 36, as in the case of the control member 36 made transparent in fig. 8. Of course, other resetting means, whether elastic (leaf springs, compression springs, etc.) or non-elastic (magnet equivalent), may alternatively be implemented to ensure this function of automatically resetting the manual mechanical control member 36 to said locking position of the locking means.
According to another variant of the hair-cutting apparatus 1 of the present invention (not shown), the attachment 6 is mounted in rotation with respect to the handle 2 along the rotation axis C/C' of the attachment 6 so as to occupy only said first angular configuration, which permits a variable angular orientation of the attachment 6 with respect to the handle 2 within said predetermined angular range, and therefore so as to be able to oscillate in rotation between said first and second angular positions, so as to blow an air flow through said first and/or second air outlets 15, 16 of the attachment 6 (a "blowing brush" only mode). In particular, the latter appendix 6 therefore does not comprise, according to this variant, a third air outlet 33, through which third air outlet 33 the appendix 6 is able to blow an air flow when said appendix 6 occupies the second angular configuration, as described above. In this case, it is advantageously provided that the first and second angular positions constitute extreme stop positions. In this way, the hair-cutting apparatus 1 can comprise complementary stop means designed and arranged to mechanically delimit the predetermined angular range and, therefore, to mechanically limit the amplitude of rotation, oscillation of the attachment 6 with respect to the handle 2.
According to a variant (not shown), the accessory 6 is designed to be removably connected, assembled to the handle 2, so that the user can detach the accessory 6 from the handle 2, for example for cleaning or replacing the accessory 6. According to another variant remaining in the embodiment shown in the figures, the attachment 6 is designed to remain permanently integrally connected to the handle 2 of the hairdressing apparatus 1 and is therefore not provided (in normal use) to be separated from the handle 2 of the hairdressing apparatus 1 by the user. This simplifies the design and use of the hair cutting device 1. Thus, in the example shown in the figures, the air distribution duct 21 is advantageously provided with an annular peripheral lip 46 near the first end 3 of the handle 2, the annular peripheral lip 46 extending in a plane orthogonal to the extension axis a-a' of the handle 2. The appendage 6 advantageously comprises an annular groove complementary to said annular peripheral lip 46 and designed to receive the annular peripheral lip 46 for sliding therein. Such complementary annular grooves may generally comprise groove portions 47A, 478, these groove portions 47A, 478 being carried respectively by the first and second housing elements 17A, 17B (fig. 9 and 11) of the housing 17 of the accessory 6, so as to capture said annular peripheral lip 46 when said first and second housing elements 17A, 178 are fixed to each other and thus ensure the rotational assembly of the accessory 6.
