Definitions

• the present invention relates to devices intended to be used for hair, in particular for the hair styling process called "brushing”, or “shaping”, or even “heat brushing”, and for cutting hair.
• Brushing is a technique for drying and shaping hair well known to hairdressers, which requires the combined action of a hand dryer and an essentially cylindrical hand brush. This styling technique involves working, strand by strand, damp hair using a brush, comb or fingers, while drying them with a hand dryer.
• the hairdresser can give volume or curl hair. For this, he must each time take a lock of wet hair, wind it on the hand brush, and dry it in the hair dryer, so as to obtain a shape determined by the diameter of the brush.
• Such a method requires that the hairdresser can easily use, in succession, brushes of different diameter, each adapted to a different length or position of lock of hair.
• document US 2009/0229624 A1 describes a kit comprising a plurality of brushing rollers, at least one removable gripping handle to which one of the brushing rollers can be mechanically attached, and a housing of storage defining a receiving compartment sized to receive and contain the brushing rollers.
• Mechanical attachment of the brushing roller to a removable gripper handle requires the operation of a release button to release the brushing roller away from the removable gripper. It is then necessary to use two hands, one to hold the removable gripping handle, the other to hold the brushing roller until they are separated, which is not ergonomic and requires the hairdresser to release the handle. hair-dryer.
• Document US 2013/0133683 A1 describes a brushing roller which is retained on a removable handle by a magnet.
• the removable handle comprises a gripping section and an attachment section configured in a cone to removably engage in a corresponding conical housing of a handle adaptation element provided inside the brushing roller.
• Two opposing flat surfaces are provided both on the conical securing section and in the conical housing of the handle adapter element, to oppose the relative rotation of the removable handle and the brushing roller.
• a retainer magnet is provided in the bottom of the tapered housing of the handle adapter member, and a retainer magnet is also provided at the end of the handle attachment section, to axially retain the handle and the handle roller. brushing engaged one on the other in the assembly position.
• a circumferential flange is provided at the proximal end of the brushing roller, to constitute a bearing surface for the disengagement of the brushing roller from the handle by an axial thrust.
• a removable handle comprises a conical fixing section which engages in a conical opening formed inside a hair roller, the two elements being retained by magnets.
• the teeth illustrated in the figures are not contiguous, neither as regards the male part, nor as regards the female part. The description does not provide any additional information. In other words, none of the toothed portions are continuous.
• a hair roller comprises a male conical fixing section which engages in a conical opening formed inside a handle, the two elements being retained by a magnet and a metal crown. Engagement ribs, provided throughout the tapered attachment section and the tapered opening, prevent axial relative rotation of the handle and hair roller.
• the teeth illustrated in the figures are crenellated and are contiguous, both as regards the male part and as regards the female part. The description does not provide any additional information. In other words, none of the toothed portions is discontinuous.
• Document US Pat. No. 9,173,478 B2 describes a dental instrument for applying a gel or a paste in the mouth.
• a coupling between an instrument body and an instrument head comprises on the instrument body a male cylindrical fixing section which engages in a cylindrical opening formed inside the instrument head. Two diametrically opposed ribs of the cylindrical opening engage in two of the eight grooves of the male cylindrical section, to index and block the relative orientation of the parts. Means are not provided for carrying out the coupling and uncoupling of the parts with one hand.
• the object of the invention is to further facilitate the handling of the instruments used for hairdressing the hair, in particular by allowing the hairdresser to keep the hair dryer or other hairdressing instrument in one hand at all times and to take, to handle or rest with his only other hand the other tools for cutting or shaping locks of hair during a brushing step.
• the object of the invention is in particular to facilitate the handling and interchangeability of different instruments, each comprising an instrument body shaped to interact with the hair and on which a gripping handle can be removably attached. .
• the handling should in particular be facilitated by the fact that the user does not need to index the angular position of the gripping handle when it is fixed to a body of instrument, and by the fact that the invention avoids the risk of mechanical blocking of the handle when it is fixed to an instrument body as well as when it is withdrawn away from an instrument body.
• the invention aims to retain the advantageous properties of a hollow instrument body and of a reduced temperature gripping handle.
• the invention aims to facilitate the handling and interchangeability of instruments by significantly promoting the engagement of the gripping handle on the instrument body.
• the invention aims to facilitate the handling and interchangeability of instruments by promoting on the one hand a good attachment of the instrument body to the gripping handle, and on the other hand the voluntary separation of the gripping handle away from the instrument body, using only one hand without excessive effort and without risk of jamming.
• the invention provides an instrument for treating hair, having the characteristics of the preamble below:
