• first plane 1211 and second plane 1221 are not arranged staggered or "head to tail".
• the articulation 12 being connected on the one hand to the accessory 2 and on the other hand to the handle 11, the articulation 12 allows the accessory 2 to be movable between the first position and the second position, that is to say, allows the accessory 2 to be oriented either along the first axis P-P ', or along the second axis A-A', as can be seen in Figures 6 and 7 in particular .
• the accessory 2 can therefore, depending on the will of the user who is going to handle the device, either in the axis of the handle 11 or bent relative to the handle 11.
• the joint 12 further comprises a locking device 123.
• the latter is then designed to lock the joint 12 in the first position or in the second position, that is to say to maintain the articulation 12 in one or the other of the positions, avoiding any untimely movement of the articulation 12.
• the locking device 123 is movable between two positions: a free position, allowing the accessory 2 to evolve between said at least first position and second position, and a locked position locking said accessory 2 in one of said first position or second position.
• FIG. 11 illustrates this locking device 123 in detail.
• the latter thus comprises a third control device 1231, in this case a push button, intended to be manipulated by the user of the hairdressing appliance.
• the third control device 1231 projects radially from the first inclined face 121, so that it can be easily operated by the thumb or forefinger of the hand of the user who holds the hairdressing appliance by the handle 11 as can be done. understand it in Figures 1 to 4.
• the locking device 123 also includes a lug 1232 connected to the third control device 1231.
• the lug 1232 protrudes longitudinally from the first plane 1211 of the first inclined face 121, in the same direction as the guide and hooking device 1212.
• the lug 1232 is therefore arranged perpendicular to the third control device 1231.
• the lug 1232 is arranged perpendicular to the third control device 1231. 'lug 1232 is driven in a translational movement, vertical with reference to the figures, when the third control device 1231, in this case the push button, is actuated by the user.
• the locking device 123 also comprises a first notch 1233 and a second notch 1234 each made in the second inclined face 122. Said first notch 1233 and second notch 1234 are diametrically opposed as can be seen in FIG. 11. Each of said first notch 1233 and second notch 1234 is then designed to alternately receive lug 1232.
• the lug 1232 will then prevent the relative rotation between the first inclined face 121 and second inclined face 122, thus ensuring that the joint 12 is held in position, regardless of the force exerted on the accessory.
• the lug 1232 is disposed in the first notch 1233, the articulation 12 is locked in the first position, that is to say that the entire articulation 12 is oriented along the first axis P-P ', that is to say that the accessory 2 and the main body 1 are aligned along the first axis P-P '.
• Said first inclined side 121 and second inclined side 122 are then arranged in a staggered manner or “head to tail” as explained previously.
• the lug 1232 By actuating the third control device 1231, the lug 1232 is moved in translation, the lug 1232 is found inside the complementary guiding and hooking device 1222, in this case inside the groove , which allows the relative rotation between the first inclined pan 121 and second pan inclined 122. It is then possible to rotate the articulation 12 so as to make it pass from the first position to the second position or vice versa.
• the locking device 123 also comprises an elastic return device, a spring for example (not shown), in the locked position.
• the free position is an unstable position while the locked position is a stable position.
• the elastic return device ensures automatic locking of the joint 12 in one or the other of the first or second position as soon as the lug 1232 arrives in front of one or the other of the first notches.
• joint 1233 or second notch 1234 that is to say as soon as the articulation 12 arrives in one or the other of the first or second position, that is to say as soon as the accessory 2 arrives in the 'either of the first or second position. This makes the use of joint 12 more intuitive.
• the hinge 12 comprises an air channel 124 designed to allow the air flow from the air inlet 110 to the air outlet 24, the air being set in motion by the device for setting the air in motion, as explained above.
• the air channel 124 comprises a tube 1241 which delimits said first planes 1211 and second plane 1221.
• the air channel 124 comprises a plurality of walls 1242, disposed radially inside the tube 1241. Said plurality of walls 1242 thus form different channels which make it possible to properly orient the air flow, in particular in a longitudinal direction.
• the walls 1242 make it possible in particular to reduce, or even eliminate, the rotating or swirling component of the air flow leaving the device for setting the air in motion.
• the accessory 2 can move between said first position and second position, in particular thanks to the relative mobility between the first inclined side 121 and second inclined side 122.
• the accessory 2 is thus movable between two positions:
• each of the first and second positions allows the rotation of the accessory 2 by the motor for driving the accessory in rotation arranged at the end. 'inside the accessory holder 4.
• the articulation 12 is designed to be movable between exactly two positions: the first position or the second position. Consequently, the accessory 2 is movable between exactly the first position and the second position. In other words, the accessory 2 is designed to operate normally, that is to say to be able to be rotated by the accessory drive motor, only in these two positions. This makes it possible to limit the number of scenarios for using the hairstyling device, which simplifies the use of the device for the user while offering him an ergonomic device. It also limits the costs of designing and manufacturing the styling device.
• Said first position and second position are stable positions defined by design, which prevents the user from having the accessory 2 in an inadequate position (in fact, there is no possible blocking in an intermediate position) and simplifies its handling of the styling device, while limiting the design and manufacturing costs of the device.
• the accessory 2 could move between three, four, five or a plurality of different positions, each of them allowing the rotation of the accessory 2 around the second. axis A-A '.
• accessory 2 could move between, not different predefined positions, but an infinity of positions, that is to say that accessory 2 could work in any position.
• a flexible joint comprising for example a cardan joint.
• the second axis A-A ’ forms an angle ⁇ different from the right angle with the first axis P-P’ when the attachment 2 is in the second position. More precisely, the angle a is equal to 150 ° as can be seen in FIG. 7.
