• the actuation of the trigger 54 similarly to the actuation making it possible to go from a position of the trigger illustrated in FIG. 2 to that illustrated in FIG.
• proximal spacing 81 and the first intermediate spacing 82 in which can be placed hair.
• the release of the trigger 54 allows the concomitant translation backwards, under the action of the springs, the distal ring 13 and the intermediate rings 8-12, which first tightens the first intermediate spacing 82 until that the proximal ring 7 also translates, the proximal gap 81 then tightening in turn.
• the rings 8-13 in contiguous position form a roller around which can be wound the hair which is held at their ends, at the tips, for the realization of a looping.
• An alternative embodiment could be envisaged according to which all the rings 7-13 would move together and concomitantly to reveal only the proximal spacing 81 when the trigger 54 is activated. In this case, it would be advisable to add an element abutment (not illustrated) complementary subject to the proximal ring 7, which would come into contact with the fingers 92, 93 of the locking piece 88.
• the hairdressing apparatus includes a sleeve 96 which is configured to be positioned around the mandrel 3 when the rings 7-13 are disposed contiguously.
• the sleeve 96 comprises bristles (not shown in Figure 9 for a better reading thereof) which are distributed radially and uniformly on the sleeve at holes 97 which allow the assembly of these bristles on the sleeve 96.
• sleeve 96 comprises two semi-cylindrical portions 98, 99 which are mounted in pivot connection 100 relative to one another along a longitudinal axis X1 parallel to the longitudinal axis X at their first edges 98a, 99a; which makes it possible to open the sleeve 96 to position it around the mandrel 3 and then to close the sleeve to tighten it around the mandrel 3.
• the second edges 98b, 99b of the two parts 98, 99 are held together in closed position, by means of two clips 101, 102, illustrated in Figure 9.
• This sleeve 96 allows to use the hairstyling device 1 for brushing hair.
• the aforementioned characteristics of the hairdressing appliance 1 offer several possible uses.
• heating means that is to say the heating elements 31, 32 which provide thermal conduction through the drum 4 and the rings 7-13 and, in addition or independently, the fan 36 and the second heating element 39 which allow the blowing of hot air through the base 3a and the head 3b of the mandrel 3, along the outer surface of said mandrel 3.
• the hairdressing appliance 1 comprises other characteristics such as a control system of the heating means for adjusting the heating temperature of the heating elements 31, 32, 39 and for adjusting the speed of the fan 36.
• the device for actuating rings 7-13 while retaining a tightening of these rings 7-13 independently of one another and a constant pressure between them.
• the trigger 54 and the connecting rods 56, 57 may be replaced by another system for actuating the transmission part 47.
• the transmission system that is to say the transmission part 47, can also be modified.
• Variants of heating elements 31, 32 may also be found instead of the positive temperature coefficient sensors. It is also possible to fix the heating elements 31, 32 directly on the inner wall 30 of the drum 4, without providing the housings 28, 29.
• the embodiment described above has the advantage of limiting the bulk of the chamber 41 of the drum 4, which advantageously contributes to arranging the actuating device rings 7-13 directly in said chamber 41 and blowing air hot by the head 3b of the mandrel 3, in addition to a blowing of hot air through the base 3a of said mandrel 3.
