Description

Multifunctional haircutting device of the rotating brush type

Technical Field

The present invention relates to a multifunctional hair-cutting device of the rotating brush type, having the purpose of allowing to carry out several types of hair-cutting through one and the same device. In a preferred embodiment, the hair-cutting apparatus according to the invention allows the functions of a curler, a straightener, a brush and a blower to be integrated in order to achieve at least three different haircuts for dry or damp hair.

Background

In the field of multifunctional hair cutting devices of the rotating brush type, documents JPS54136961A, JPS54136959A, EP1558106 and CN102783802 are known.

In document JPS54136961A, a hair cutting device comprises a heated mandrel equipped with dishes arranged in succession one after the other along an axis. The disks are pressed against each other by means of a joint which is equipped with a spring and which is arranged at the end of the shaft, the spring exerting a pressure on these disks. When hair is positioned between the sides of the discs and in contact with the shaft, the discs are spaced from each other under the stress of the hair. Once positioning such as described above is achieved, the sides of the dish apply pressure to the hair. The pulling force exerted on the joint in the direction of the axis allows to release the spring and therefore to stop the pressure exerted by the dish on the hair, so as to easily disengage the hair from the mandrel at the end of the hair treatment. This embodiment has the disadvantage that proper positioning of the hair between the dishes and contact with the shaft is not ensured, since it is necessary to force the hair between the dishes by spacing them apart. Furthermore, the hair cutting device is not ergonomic, since it requires two-handed operation, in order to use a first hand to hold the body of the hair cutting device, and a second hand to pull the joint in order to remove the hair on the mandrel after the hair is cut. The user cannot manipulate his hair while removing it from the mandrel or even while positioning it, because during this time he needs to hold the body of the device with one hand and the joint with the other hand.

In document JPS54136959A, the hair cutting device comprises a heated mandrel equipped with a shaft that houses a helical spring, the coils of which are equipped with bristles. The joint arranged at the end of the shaft is configured for setting and locking in a first position according to which the spring is compressed in order to press the loops against each other after setting the hair between said loops, or in a second position according to which said spring is relaxed in order to space the loops and allow the hair to be removed after haircut. This embodiment has the disadvantage that the pressure exerted on the hair is not adjusted according to the variation of the amount of hair between the loops, since the joint is in a binary manner

Is disposed in either the first position or the second position. In fact, the amount of hair placed between all the loops will vary the pressure exerted on these loops by the joint, which is transmitted to the hair. Furthermore, the hair cutting device is not ergonomic, since it requires two-handed operation in order to hold the hair cutting device with a first hand and to push or pull the joint with a second hand in order to set it in the first or second position. When pushing the joint with one hand and simultaneously operating the device with the other hand, the hair may partially detach from the loop of the spring and not be pressed correctly by said loop.

In documents EP1558106 and CN102783802, the hair cutting device comprises a heating mandrel equipped with a shaft on which a helical fixed profile or a helical movable profile is arranged. The movable profile may abut against or be spaced from the fixed profile under the action of the control button. Hair is arranged between the movable and fixed profiles in contact with the shaft, the actuation of the control button then allowing the application of pressure to the hair between the two fixed and movable profiles loops, while the release of the button conversely allows the release of the hair after haircut. This embodiment has the drawback of exerting a different pressure on each lock of hair that is clamped between each pair of loops of the movable and fixed profiles, because of the different thicknesses of the locks of hair that are compressed between said movable and fixed loops. In fact, each loop of the active profile has a stop position depending on the thickness of the lock of hair gripped between the active loop and the fixed loop. These differences in pressure can have an effect on the homogeneity of the hair cut.

Disclosure of Invention

The present invention overcomes the above-mentioned disadvantages. To this end, the invention relates to a hair cutting device comprising a main body configured for operating the device, a hair grooming mandrel which extends the main body along a longitudinal axis X and allows acting on the hair in order to achieve cutting. The haircutting device further comprises heating means of the mandrel, which allow drying of the damp hair while it is being treated using the mandrel, even allowing a better treatment of the hair to be obtained during the course of its operation using the mandrel. Further, the mandrel comprises on its outside a proximal ring, a distal ring and at least one intermediate ring arranged between the proximal and distal rings. The rings are configured to be connectively disposed between each other by sliding in one direction so as to constitute a roll, or spaced apart from each other by sliding in the other direction so as to allow hair to be inserted into the space formed between the rings. Furthermore, the hair cutting device comprises drive means of the rings, which drive means are configured at least for spacing the rings for inserting hair into the spacing, and for clamping the rings independently relative to each other according to the thickness of the hair arranged between the rings, while applying a constant pressure to the hair. Therefore, the interval of the rings for releasing the hairs or the interval for disposing the hairs on the mandrel is easily implemented. The independent clamping of the rings, while ensuring a constant pressure, allows to treat in the same way the hair placed in the spaces between the rings, irrespective of the variations in thickness that may exist between the locks of hair placed in the spaces. These features of the hair cutting device according to the invention allow the hair to be straightened using the device by arranging the hair in the spaces between the clamped rings and then applying a pulling force to the hair. While the rolled shape of the mandrel allows curling of dry or damp hair when the rings are joined together. Other shaping of the hair can be considered by means of the hair cutting device.

In accordance with an embodiment of the hair cutting device, the rings are configured for being mounted continuously slidingly with respect to each other along the longitudinal axis X. Furthermore, the drive means comprise a transmission system configured to slide the rings in the manner of a sleeve when the rings are spaced or clamped, by acting on the distal ring when the rings are spaced or clamped, and then on the intermediate ring and the proximal ring successively.

According to an embodiment of the transmission system described above, the transmission system comprises: a transmission part slidingly mounted with respect to the spindle along the longitudinal axis X; an accompanying mechanism (proximate' associatetissement) at a distal end of the drive component that accompanies the distal end ring; a locking mechanism arranged on each ring so as to come into contact with the front ring at the end of a certain stroke in the direction of the longitudinal axis X or in the opposite direction to the direction of the longitudinal axis X; and a return mechanism for the drive element that allows the endless belt to be returned to the connected position.

Preferably, according to this embodiment of the transmission system, each ring comprises, in a longitudinal section plane, a shape of castellations configured for successively sliding the rings into each other so as to abut against the front ring at the end of a certain stroke during clamping of the rings.

Preferably, according to this embodiment of the transmission system, the locking mechanism of the distal ring and of the at least one intermediate ring comprises a leg which follows the ring and which abuts against the front ring at the end of a certain stroke during the spacing of the rings.

Preferably, according to this embodiment of the transmission system, the accompanying mechanism includes a distal end branch accompanying the distal end portion of the transmission part and the distal end ring.

According to an embodiment of the drive device, the drive device comprises a drive pin arranged on the body and a connection mechanism arranged between the pin and the transmission system. In the aforementioned embodiment of the transmission system, the pin allows to activate the transmission part by means of a connection mechanism to translate along the longitudinal axis X.

According to the hair cutting device of the present invention, said spindle comprises a roller comprising a proximal end portion and a distal end portion. The distal portion is mounted slidingly along the longitudinal axis X with respect to the proximal portion, preferably by engaging the distal portion in the interior of the proximal portion. Furthermore, the ring is slidably mounted on the drum, preferably on the proximal end portion. However, a variant is conceivable according to which the proximal portion is engaged in the distal portion in order to achieve this sliding, the ring being slidingly mounted on the distal portion of the drum.

According to the aforementioned preferred embodiment of the mandrel, the distal ring follows the distal end portion of the drum and is slidingly mounted with respect to the proximal end portion of the drum. Furthermore, the at least one intermediate ring and the proximal ring are mounted in a sliding connection relative to the proximal portion.

According to this embodiment of the spindle, the drum is mounted in a pivotal connection with respect to the body along the longitudinal axis X. Furthermore, the hair cutting device comprises a rotary drive mechanism for the drum. The hair cutting device therefore has a rotating spindle which facilitates the operation of the device during hair treatment, in particular for achieving curling. However, a simplified embodiment variant of the hair cutting device according to the invention with a spindle that does not rotate relative to the main body is conceivable.

According to this embodiment of the haircutting device, with the rotating spindle, the transmission system is arranged inside the drum, the connection means being configured for translating the transmission system along the longitudinal axis X inside the proximal portion of the drum.

According to this embodiment of the mandrel, the heating means of the haircutting device comprise at least one heating element arranged inside the drum. Furthermore, the roller is made of a material ensuring thermal conduction, so as to transfer the heat of the heating element towards the hair during treatment. Preferably, the at least one heating element is arranged on the inner wall of the drum, which allows a more precise heating of the outside of the mandrel and at the same time provides a temperature range which is larger than when the heating element is simply arranged inside the drum without direct contact with the drum, however in less efficient embodiment variants this solution is also conceivable.

In accordance with an embodiment of the hair clipping device, the heating means comprise a hot air blowing system configured for spraying hot air along an outer wall of the spindle. Preferably, the spindle comprises a base and a head, the hot air blowing system being configured for ejecting hot air at least through outlets arranged at the base and the head. This optimizes the distribution of the hot air blown towards the hair on both longitudinal sides of the mandrel. Other embodiment variants are conceivable, for example a hot air blast system configured to eject hot air radially through the ring relative to the mandrel.

According to the invention, the hair cutting device comprises a locking system configured for acting on the drive means and simultaneously moving the ring in the connected position into a spaced position spaced with respect to the base of the spindle or, conversely, when the drive means are activated, simultaneously moving the ring in the connected position into a clamped position clamped with respect to the base. This embodiment allows curling to be achieved by the hairstyling apparatus by first, simultaneously spacing the rings, then simultaneously clamping the rings, pre-locking the ends of the locks between the proximal ring and the base, then winding the locks around the spindle, which is either manual when the spindle is non-rotating or automatic when the spindle is rotating and electrical. The locking system facilitates the clamping of the lock ends by the ring, after which they are wound around the spindle in order to achieve the curling. According to this embodiment of the hair cutting device, the hair cutting device comprises a control button of the locking system, the control button being configured for activating and deactivating the locking system. Curling of the hair can also be achieved on dry or damp hair by the heating mechanism of the mandrel.

According to the present invention, the hair cutting device comprises a sleeve configured for attachment on the spindle. The sleeve includes bristles. The sleeve can thus be placed on or removed from the mandrel as required in order to achieve hair straightening and shaping by means of a haircutting device, possibly supplemented with a heat treatment for damp hair as required.

In a preferred embodiment of the hair cutting device according to the invention, said hair cutting device comprises between 4 and 8 intermediate rings, and preferably 5 intermediate rings.

Detailed Description

As shown in fig. 1 to 4, the hairdressing apparatus 1 includes a main body 2 and a spindle 3. The spindle 3 is arranged in the longitudinal extension of the body 2 along the longitudinal axis X. The mandrel 3 comprises a roller 4, said roller 4 comprising a proximal portion 5 and a distal portion 6, as shown in more detail in figures 3, 4 and 6. The distal portion 6 is mounted slidingly inside the proximal portion 5 along the longitudinal axis X.

The mandrel 3 comprises a proximal ring 7, five intermediate rings 8-12 and a distal ring 13, as shown in fig. 1-3. The proximal ring 7, the intermediate rings 8-12 and the distal ring 13 are also shown in fig. 5 to 7. The number of intermediate rings may vary depending on the length of the mandrel 3, and even depending on the amount of pressure that is desired to be applied to the hair in a single hair treatment operation. Preferably, between 4 and 8 intermediate rings are selected. As shown in fig. 1 to 7, it is observed that the proximal ring 7, the intermediate rings 8-12 and the distal ring 13 have a crenellated shape in a longitudinal section plane traversed by the longitudinal axis X.

As shown in more detail in fig. 5 and 6, the proximal ring 7 comprises an inner cylinder 7a and an outer cylinder 7b, which inner cylinder 7a and outer cylinder 7b are connected to each other by a shoulder 7c, and the proximal ring 7 further comprises a circular base 7d, which circular base 7d partially closes the distal end of the outer cylinder 7 b. Similarly, the intermediate rings 8-12 each comprise an inner barrel 8a-12a and an outer barrel 8b-12b, the inner and outer barrels 8a-12a and 8b-12b being connected to each other by shoulders 8c-12c, and the intermediate rings 8-12 further comprise circular bases 8d-12d, the circular bases 8d-12d partially closing the distal ends of the outer barrels 8b-12 b. The distal ring 13 also comprises an inner barrel 13a and an outer barrel 13b, the inner barrel 13a and outer barrel 13b being connected to each other by a shoulder 13c, but the distal ring 13 does not have a circular base. The distal end 14 of the outer barrel 13b of the distal ring 13 is embedded in a reinforcing head 15 of the distal portion 6 of the drum 4, as shown in particular in fig. 5 and 6. The circular base 7d of the proximal ring 7 is mounted sliding along the longitudinal axis X on the inner barrel 8a of said first intermediate ring 8. Likewise, the circular base 8d-11d of the intermediate ring 8-11 is mounted sliding continuously along the longitudinal axis X on the inner barrel 9a-12a of the rear intermediate ring 9-12. The circular base 12d of the last intermediate ring 12 is slidably mounted along the longitudinal axis X on the inner barrel 13a of the distal ring 13.

The hair cutting device 1 comprises a coupling part 16 as shown in fig. 1 to 6. The connecting part 16 is arranged along a longitudinal axis X and comprises a freewheel 17 accompanying a hollow shaft 18. The distal end of the flywheel includes a shoulder 17a as shown in more detail in figures 5 and 6. As shown in more detail in fig. 1 to 6, the proximal portion 5 of the drum 4 comprises a base 19, the proximal portion of said base 19 also comprising a shoulder 19 a. This base 19 is assembled with the flywheel 17 by means of a set screw housed in a position 20 foreseen for its screwing, as shown in figures 1 to 6, said assembly allowing the formation of a female neck 21, said female neck 21 being constituted by the opposite arrangement of said

shoulder

17a and 19a on the flywheel 17 and base 19, respectively, as shown in figures 5 and 6.

As shown in more detail in fig. 1 to 6, the main body 2 comprises, at its distal end 2a, an internal cylindrical portion 22, in which the flywheel 17 of said connecting part 16 is housed, and in which the base 19 of the proximal end portion 5 of the drum 4 is partially housed in said internal cylindrical portion 22. The inner cylindrical portion 22 comprises bosses 23, each equipped with a protruding pin 23a, preferably 6 and uniformly distributed around said inner cylindrical portion 22. These male pins 23a are housed in a female neck 21, said female neck 21 being arranged between the freewheel 17 and the base 19, as shown in more detail in particular in fig. 5 and 6, and these male pins 23a ensure the pivotally coupled mounting of the connecting element 16 and of the proximal portion 5 with respect to the main body 2 along the longitudinal axis X. The hollow shaft 18 of the connecting part 16 extends in the body 2 along a longitudinal axis X and follows, at its proximal end 18a, a distal end 24b of a drive shaft 24, also hollow, as shown in fig. 1 to 4 and 6. The proximal end portion 24a of the drive shaft 24 is connected to a motor 25 for driving rotation. Two rings 26a, 26b are additionally mounted between the drive shaft 24 and the inner wall 27 of the body 2, so as to ensure the pivotal connection of the proximal portion 5 of the drum 4, the connecting part 16 and the drive shaft 24 all with respect to the body 2 along the longitudinal axis X.

As shown in fig. 1, 2, 5 to 8, the proximal portion 5 of the drum 4 is hollow and comprises two

housings

28, 29, said two

housings

28, 29 being arranged longitudinally opposite one another on a cylindrical inner wall 30 of said proximal portion 5. These

cavities

28, 29 are configured for receiving said

heating elements

31, 32, which are preferably PTC sensors with a positive temperature coefficient. These

heating elements

31, 32 are electrically connected by means of

cables

33, 34, said

cables

33, 34 passing through the hollow shaft 18 and the transmission shaft 24 of the connecting part 16, said ends 33a, 34a of these

cables

33, 34 being connected by means of a rotating electrical connector 35 to an electronic management card (not shown in the figures), as shown in figures 1 and 2. The

heating elements

31, 32 are thus in direct contact with the roller 4, the roller 4 being in contact with the rings 7-13. Since the transfer of heat through the drum 4 by thermal conduction is improved by direct contact with the

heating elements

31, 32, this allows a more precise adjustment of the heating temperature of the rings 7-13 and provides a greater adjustment range of the heating temperature. Therefore, a material is selected which ensures good heat conduction for implementing the drum 4, for example, aluminum.

As shown in fig. 1 to 4, the fan 36 is disposed inside the main body 2 at the proximal end portion 2b thereof. A hollowed-out cover 37 closes this proximal portion 2b and ensures air intake when the fan 36 is activated, said fan 36 blowing air into the chamber 38 of the body 2. A second heating element 39, for example a sensor with a positive temperature coefficient, is arranged in a middle portion of the chamber 38. The air blown by the fan 36 therefore flows through the second heating element 39, which allows it to be heated, after which it propagates into the chamber 38 as far as the distal end 2a of the main body 2.

As shown in fig. 1 to 6, the projections 23 on the internal cylindrical portion 22 of the main body 2 allow to maintain a spacing from the flywheel 17 of the connecting part 16 and from the base 19 of the proximal portion 5 of the drum 4, which allows to constitute a duct communicating with the chamber 38 and opening onto said air outlet 40 at the distal end 2a of the main body 2. These air outlets 40 allow blowing hot air in a longitudinal direction, starting from the base 3a of the mandrel 3, at the surface of the outer cylinders 7b-13b of the rings 7-13 constituting the outer wall of said mandrel 3.

As shown in fig. 1-6, the proximal and

distal end portions

5, 6 of the drum 4 are hollow and define a chamber 41. The flywheel 17 of the connecting element 16 comprises four openings 42 communicating with the chamber 41 of the drum 4. Thus, the hot air is blown by the fan 36 into the chamber 41 up to the stiffening head 15 of the distal portion 6 of the drum 4. The closure 43 comprises terminals 44 allowing to be fixed together with the reinforcement head 15 by means of screws (not shown). These terminals 44 allow to preserve a space 45 between the inner wall 43a of the closure 43 and the reinforcement head 15, said space 45 forming a channel communicating with said chamber 41. Furthermore, the inner wall 43a has a curved shape, such as shown in fig. 1 to 3, which allows said space 45 to constitute a deflector having an air outlet 46 at the head 3b of the mandrel 3 oriented towards said ring 7-13. This air outlet 46 allows blowing hot air at the surface of said outer cylinder 7b-13b in the direction of the longitudinal axis X towards the ring 7-13.

The hair-cutting apparatus 1 comprises a transmission element 47 as shown in fig. 1 to 8. The transmission element 47 comprises two arms 48, 49 extending longitudinally in the chamber 41 of said drum 4. The two arms 48, 49 are mounted sliding in the direction of the longitudinal axis X, passing through two through holes 50, 51 arranged on the freewheel 17 of the connecting part 16. Thanks to this sliding connection, therefore, the rotation of said coupling element 16 driven by the motor 25 allows to simultaneously drive the transmission element 47 in rotation along the longitudinal axis X. The transmission element 47 comprises a crosspiece 52, said crosspiece 52 following the distal ends 48b, 49b of said arms 48, 49, such as shown in fig. 1 and 2. Likewise, the transmission part 47 comprises a guide ring 53, the guide ring 53 following the proximal end portions 48a, 49a of the arms, the guide ring 53 being mounted sliding along the longitudinal axis X with respect to the hollow shaft 18 of the connecting part 16. Upon activation of the motor 25, the crosspiece 52 and the guide ring 53 are driven in rotation along the longitudinal axis X together with the accompanying two arms 48, 49.

As shown in fig. 1 to 4, the hair cutting device 1 comprises a pin 54, said pin 54 being mounted on the outside of said main body 2 by means of a pivoting connection 55 and allowing to drive two links 56, 57 to which it is attached. The distal ends 56b, 57b of the links 56, 57 each include an elongated opening 58, 58'. The slide ring 59 is in sliding contact with the guide ring 53, as shown in fig. 1 to 4 and 6. The sliding ring 59 comprises two

projections

60, 61 extending opposite one another, as shown in particular in fig. 3, 4 and 6, and the two projections 60 are each received in an opening 58, 58' in the connecting rod 56, 57. The sliding ring 59 is also mounted slidably along the longitudinal axis X opposite the hollow shaft 18 of the connecting part 16. The driving of the pin 54 from the first position shown in fig. 2 towards the second position shown in fig. 1 allows to translate the sliding ring 59 towards the front of the hollow shaft 18, which simultaneously drives the translation of the guide ring 53 and of the transmission part 47 towards the front. When the motor 25 is activated, the guide ring 53 is driven in rotation and rubs against the sliding ring 59 accompanying the links 56, 57, as described above.

As shown in fig. 1 to 6, the hair cutting device 1 comprises a proximal leg 62, five intermediate legs 63-67 and a distal leg 68. The proximal leg 62 is axially arranged and passes through two

elongated openings

69, 70, said

openings

69, 70 being longitudinally arranged on the inner barrel 7a of the proximal ring 7, the

ends

62a, 62b of said proximal leg 62 being housed in two

holes

103a, 103b, said two

holes

103a, 103b being radially arranged on the proximal portion 5 of said drum 4. The proximal ring 7 is then mounted slidingly along the longitudinal axis X with respect to the proximal portion 5, with a travel limited to the length of the

openings

69, 70.

As shown in particular in fig. 1, 2, 5 and 6, the proximal portion 5 of the drum 4 comprises two

longitudinal openings

71, 72, said two

longitudinal openings

71, 72 extending parallel to the longitudinal axis X and being oppositely arranged on the proximal portion 5. Likewise, the distal portion 6 of the drum 4 comprises two

grooves

73, 74, said two

grooves

73, 74 opening into the proximal end portion 6a of said distal portion 6 and being oppositely arranged in alignment with the

longitudinal openings

71, 72, respectively, as shown in particular in fig. 5 and 6.

As shown in particular in fig. 1 to 6, the intermediate branches 63-67 are arranged radially and each pass through the two

longitudinal openings

71, 72. The two ends 63a-67a of said intermediate branches 63-67 pass through two through holes 75a-79a, respectively, as shown in fig. 6, said through holes 75a-79a being arranged radially and oppositely on the inner cylinders 8a-12a of said intermediate rings 8-12, said inner cylinders 8a-12a being mounted slidingly along the longitudinal axis X with respect to the proximal portion 5 of the drum 4. This design allows implementing the intermediate ring 8-12 to be mounted with a sliding connection along the longitudinal axis X with respect to the proximal portion 5 of the drum. Furthermore, the two ends 63a-67a, 63b-67b of the intermediate branches 63-67 are housed inside the castellated front ring 7-11, in the portion corresponding to the outer cylinder 7b-11b of said front ring 7-11, as shown in FIG. 6. Furthermore, as previously mentioned, the inner cylinders 8a-12a of the intermediate rings 8-12 are slidably mounted along the longitudinal axis X with respect to the circular bases 7d-11d of the front rings 7-11. Thus, each intermediate ring 8-12 can slide along the longitudinal axis X with respect to the ring 7-11 located in front of the intermediate ring 8-12, either towards the downstream until the ends 63a-67a, 63b-67b of said intermediate legs 63-67 abut against the inside of the circular base 7d-11d of the front ring 7-11, as shown in fig. 3, or towards the upstream until the shoulders 8c-12c on the intermediate ring 8-12 abut against the outside face of the circular base 7d-11d of the front ring 7-11, as shown in particular in fig. 5 and 6. Furthermore, the rotation of the intermediate rings 8-12 with respect to the front rings 7-11 is locked by the

longitudinal openings

71, 72 through which said intermediate legs 63-67 pass, which ensures a sliding mounting of each intermediate ring 8-12 with respect to the ring 7-11 at the front thereof with a limited stroke.

Similarly to said features, as shown in particular in fig. 6, the distal leg 68 is axially arranged and passes through two

longitudinal openings

71, 72 of the proximal portion 5 of the drum 4. The two ends 68a of the distal leg 68 each open into two through holes 80a, the two through holes 80a being arranged diametrically opposite on the inner barrel 13a of the distal ring 13, the inner barrel 13a of the distal ring 13 being slidably mounted along the longitudinal axis X with respect to the proximal portion 5 of the drum 4. This design allows to implement a sliding connection mounting of the distal ring 13 along the longitudinal axis X with respect to the proximal portion 5 of the drum. Furthermore, the two

ends

68a, 68b of the distal leg 68 are housed inside the intermediate ring 12 located in front thereof, in the portion corresponding to the outer barrel 12b of the intermediate ring 12. As mentioned above, the inner barrel 13a of the distal ring 13 is slidably mounted along the longitudinal axis X relative to the circular base 12d of the forward intermediate ring 12. Thus, the distal ring 13 can slide along the longitudinal axis X with respect to the intermediate ring 12 in front of it, either downstream until the

ends

68a, 68b of the distal legs 68 abut against the inside of the circular base 12d of the intermediate ring 12, or upstream until the shoulder 13c on the distal ring 13 abuts against the outside face of the circular base 12d of the intermediate ring 12. Furthermore, the rotation of the distal ring 13 relative to the intermediate ring 12 is locked by the

longitudinal openings

71, 72, through which the distal legs 68 pass, which ensures a sliding connection mounting of the distal ring 13 with limited travel relative to the intermediate ring 12 in front of it. The distal leg 68 additionally follows the ledge 52, and the distal leg 68 traverses the ledge 52, as shown particularly in fig. 3-5. The ends 68a, 68b of the distal leg 68 pass through two

grooves

73, 74, respectively, of the distal portion 6 of the drum, which locks the distal portion 6 in rotation along the longitudinal axis X with respect to the distal ring 13, as shown in fig. 6.

During the activation of the pin 54 from the first position shown in fig. 2 to the second position shown in fig. 1, the transmission part 47 is translated towards the front along the longitudinal axis X, since the concomitance between the crosspiece 52, the distal leg 68 and the distal ring 13 ensures the forward movement of said distal ring 13 and of the distal portion 6 of said drum 4, said distal ring 13 and of the distal portion 6 of said drum 4 being translated along the longitudinal axis X with respect to the proximal portion 5 of the drum 4. At the same time, the distal ring 13 translates relative to the intermediate ring 12 in front of it until the

ends

68a, 68b of the distal legs 68 abut against the circular base 12d of the intermediate ring 12, which drives the translation of the intermediate ring 12 along the longitudinal axis X towards the front relative to the intermediate ring 11 in front of it. When the ends 67a, 67b of the intermediate leg 67 abut against the circular base 11d of the intermediate ring 11 in front of it, the circular base 11d of the intermediate ring 11 translates with respect to the intermediate ring 10 in front of it. This action is then repeated until the last intermediate ring 8 drives the translation of the proximal ring 7, once the

ends

63a, 63b of the last intermediate legs 63 abut against the circular base 7d of said proximal ring 7. Said proximal ring 7 translates along the longitudinal axis X with respect to the proximal portion 5 of the drum and with respect to said proximal legs 62 until the

openings

69, 70 on the proximal ring 7 abut against the

ends

62a, 62b of the proximal legs 62, which stops the unwinding of the mandrel 3. In this deployed position of the mandrel 3, the proximal ring 7 has a spacing 81 relative to the base 19 of the proximal portion 5 of the drum 4, and said rings 7-13 have a spacing 82-87 therebetween. A driving device such as that described above thus allows to continuously expand the rings 7-13 in a telescopic manner until spaces 81-87 are uncovered between said rings 7-13 allowing to insert the locks of hair.

The hair cutting device 1 is configured such that, after hair has been placed in the spaces 81-87, said peg 54 automatically returns into the position shown in fig. 2 when the user releases the peg 54. For this purpose, the return mechanism ensures automatic translation of the transmission element 47 once the pin 54 is released. Preferably, these return means are constituted by two springs (not shown in the figures) arranged on the two arms 48, 49, respectively. These two springs can be arranged in the portion of the arms 48, 49 located between the free wheel 17 of the connecting part 16 and the crosspiece 52; in this case, the spring works in an extended manner. However, an arrangement of the two springs in the portion of the arms 48, 49 located between the flywheel 17 and the guide ring 53 can be considered, said springs working in compression in this case. The spring rate constant will be determined to ensure this automatic return of the peg 54. However, a smaller stiffness constant can be taken into account, which can be achieved by manually actuating the pin 54 in advance in order to bring it back into the position shown in fig. 2, said spring simultaneously pushing the transmission element 47 towards the rear and simultaneously holding the transmission element 47 against the slide ring 59.

When said transmission element 47 translates along the longitudinal axis X towards the rear of the hairdressing apparatus 1, which simultaneously drives the translation of the distal end ring 13 and of the distal end portion 6 of the drum 4, said distal end portion 6 of the drum 4 slides with respect to the proximal end portion 5 of the drum 4. The hair disposed in the distal space 87 between the shoulder 13c of the distal ring 13 and the circular base 12d of the intermediate ring 12 is pressurized until the pressure limit is reached. This pressure limit results in simultaneous actuation of the distal ring 13 and anterior intermediate ring 12. The hair disposed in the last intermediate space 86 is then stressed until a pressure limit is reached which simultaneously drives the movement of the distal ring 13 and the movement of the two last intermediate rings 12-11. The action is then repeated until the proximal ring 7 translates simultaneously with the distal ring 13 and simultaneously with all of the intermediate rings 8-12. Once the hair placed in the proximal space 81 between the shoulder 7c of the proximal ring 7 and the base 19 of the proximal portion 5 of the roller 4 is stressed, the return spring of the transmission element 47 balances the stresses exerted on the hair placed in the spaces 81-87 between said rings 7-13, regardless of the thickness of the hair placed between these spaces 81-87, due to the reduction or telescopic return of the rings 7-13 of the mandrel 3 starting from the distal ring 13 up to the proximal ring 7.

The hair cutting device 1 comprises a locking element 88, which appears in fig. 1 to 8. The locking element 88 comprises an end shaft 89, said end shaft 89 being divided into two

branches

90, 91 extending parallel to the longitudinal axis X, two

fingers

92, 93 being arranged respectively at the ends of said two branches. The reinforcement bar 94 allows to stiffen the two

branches

90, 91. Said end shaft 89 accompanies said control knob 95, said control knob 95 being mounted pivotally along the longitudinal axis X with respect to the closure 43. Said control button 95 allows to drive the locking element 88 in rotation along the longitudinal axis X from an unlocking position, in which the

fingers

92, 93 are uncoupled with respect to the first intermediate leg 63, towards a locking position, as shown in fig. 5 and 7; in the locked position, the

fingers

92, 93 are engaged between the proximal leg 62 and the first intermediate leg 63, and abut against the first intermediate leg 63. In this locked position, the actuation of the pin 54, in a manner similar to the actuation that allows moving the pin 54 from the position shown in fig. 2 to the position shown in fig. 1, allows to translate the transmission element 47 towards the front, which simultaneously moves the distal ring 13, the distal portion 6 of the drum and the closing shield 43, and therefore the locking element 88. The

fingers

92, 93 drive the first intermediate leg 63 which simultaneously moves the intermediate ring 8-12 and the distal ring 13 which remain connected. When the ends 63a, 63b of the first intermediate leg 63 come into contact with the inner face of the circular base 7d of the proximal ring 7, this proximal ring 7 is also driven in translation along the longitudinal axis X, together with the other connected rings 8-13, until the

openings

69, 70 on the inner barrel 7a abut against the proximal leg 62. The only thing that appears is the proximal space 81 and the first intermediate space 82, in which hair can be placed. The release of the pin 54 allows the simultaneous translation, under the action of the spring, of the distal ring 13 and of the intermediate rings 8-12 towards the rear, which compresses the first intermediate space 82 first until the proximal ring 7 also translates, the proximal space 81 then gripping. The rings 8-13 in the connected position form a roller around which the hair held by the tips can be wound in order to perform a curling action. A variant can be considered in which all the rings 7-13 are moved jointly and simultaneously so as to expose the proximal space 81 only when the pin 54 is activated. In this case, it is merely necessary to add supplementary locking elements (not shown) accompanying the proximal ring 7, with which the

fingers

92, 93 of the locking piece 88 come into contact.

As shown in fig. 9, the hair cutting device comprises a sleeve 96, said sleeve 96 being configured for being arranged around the spindle 3 when said rings 7-13 are arranged in connection. The sleeve 96 includes bristles (not shown in fig. 9 to make fig. 9 easier to read) radially and uniformly distributed on the sleeve at holes 97, the holes 97 allowing the assembly of these bristles on the sleeve 96. The sleeve 96 comprises two

semi-cylindrical portions

98, 99 mounted opposite each other at their

first sides

98a, 99a by a pivot connection 100 along a longitudinal axis X1, said longitudinal axis X1 being parallel to the longitudinal axis X, which allows opening the sleeve 96 in order to arrange it around the mandrel 3, after which it is closed in order to clamp it around the mandrel 3. The two

edges

98b, 99b of the two

portions

98, 99 are held between them in the closed position by means of two

clamps

101, 102, as shown in fig. 9. The sleeve 96 allows the hair cutting device 1 to be used for combing hair.

The above-described features of the hair cutting device 1 thus offer a plurality of possibilities for use. Straightening is achieved by arranging the hair in the spaces 81-87 near the roots (said spaces 81-87 being between the rings 7-13 and the base 19 of the proximal portion 5 of the drum 4) and applying pressure to the hair, after which the hair cutting device 1 is translated from the roots towards the tips. Curling is achieved by placing the tips in the spaces 81, said spaces 81 being between the base 19 and the proximal ring 7, and pressing the tips, after which the hair is wound around the rings 7-13 connected and forming a roll. Brushing of the hair is achieved by adding a sleeve 96 around the mandrel 3. These different operations can also be carried out on dry or damp hair, since a heating mechanism can be used, that is to say

heating elements

31, 32 ensuring the 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 allow the hot air to be blown along the outer surface of the mandrel 3 by the base 3a and the head 3b of the mandrel 3.

The hair clipping device 1 comprises further features, such as a heating means control system for regulating the heating temperature of said

heating elements

31, 32, 39 and for regulating the speed of the fan 36.

Other embodiments of the drive of the rings 7-13 are conceivable, while maintaining the independent clamping of the rings 7-13 and the constant pressure between the rings. The pin 54 and the links 56, 57 can be replaced, for example, with another drive system for the transmission element 47. It is also possible to modify the transmission system, that is to say the shape of the transmission element 47, the connecting element 16, the legs 62-68, the rings 7-13, the return mechanism (not shown) and the roller 4 constituted by the two proximal and

distal portions

5, 6, and at the same time achieve a similar telescopic mounting of the rings 7-13, which allows the spacing between the rings 7-13, after which said rings 7-13 are clamped independently, while maintaining a constant pressure, despite the variations in thickness of the hair in the spaces 81-87.

Other variants of the locking system of the rings 7-13, obtained by replacing the locking element 88, are also conceivable, so as to space the rings 7-13 in a connected manner from the base 19 of the drum 4.

Other variants of the heating mechanism of the mandrel 3 by replacing the

heating elements

31, 32 are also conceivable.

The above-described embodiment has the advantage of limiting the volume of the chamber 41 of the drum 4, which advantageously facilitates the arrangement of the

heating elements

31, 32 directly in the chamber 41 and in direct contact with the inner wall 30 of the drum 4, which provides the advantages described above. The preferred embodiment variant of the hair-cutting apparatus 1 therefore also allows to arrange the heating means directly in the spindle 3 and in contact with the inner wall thereof.
