Definitions
- the present invention relates to a hair treatment apparatus which is intended to carry out specific drying or shaping, in particular the smoothing, of a person's hair, and which can moreover be used with a device generally designed for hair treatment, such as a hair dryer, a styling brush, a straightener, etc.
- the generally known methods for treating the hair for shaping or drying generally use hot air blown by a hair dryer or a local application of heat and / or steam from a curling device and / or smooth.
- the devices for smoothing the hair type straighteners generally comprise two heated articulating jaws that sandwich a lock of hair and form it by applying heat.
- the hot plates of these devices, even while being coated with ceramic material, are likely, in the long term, to damage the hair due to their high operating temperature.
- the document US 5,553,632 describes a hair shaping accessory mounted at the blower end of a hair dryer.
- the accessory comprises a set of two superposed combs, one of which is fixed and the other is slidably mounted laterally relative to the first.
- the base of the comb is located above the hot air outlet end of the hair dryer.
- the moving comb is set in motion by a mechanism connected to a user-drawn cable. In operation, the combs are inserted in the open position in the hair and then the closing mechanism of the combs is actuated, which thus retain the locks of hair between their teeth. The locks thus seized are pulled upwards and dried in position by the flow of air blown by the hair dryer.
- Such a device ensures, of course, drying the hair in the stretched position and at a lower temperature, but at risk to exert a strong traction on the hair.
- the forces exerted by the teeth on the locks are not uniform and, therefore, only the thickest lock is seized, the smaller wicks nearby being able to , escape outside the combs. This results in a non-uniform, laborious and time-consuming treatment.
- this document does not address the problem of adjusting the clamping force of the combs.
- the movable comb is connected to an external cable running along the body of the device to a trigger close to the handle, but such an external cable considerably hampers the passage of the device in the hair.
- This document also describes a device for adjusting the clamping pressure of the smoothing blades by actuating in rotation a small knurled knob accessible from the side of the device.
- the setting belongs to the smoothing accessory mounted removably on the device and the actuation of the adjustment button is therefore in the vicinity of the hair. Therefore, this button is inconvenient in operation because it can hang the locks to be treated. Due to its small dimensions, this button is also difficult to handle.
- the actuation of the remote adjustment control of the body of the device is less intuitive and decreases the firmness of the handling of the handle for some users.
- the object of the present invention is to overcome the aforementioned disadvantages by providing a hair treatment apparatus in which the actuation of the control of a treatment device removably disposed at the end of the device is comfortable and safe. for the user, while retaining the advantage of a protected mechanism of contact with the hair that does not interfere with the passage of the device in the hair.

- the actuating mechanism comprises two separate mechanisms that cooperate together during the establishment of the treatment device on the device. This provides the possibility to mount the operating control of the mobile player anywhere appropriate body of the device, including, but not necessarily on the handle of the device, while retaining the advantages of a mechanism of remote actuation of the device and protected by the housing of the device and a removable treatment device. This removable treatment device can then be replaced by another device or removable accessory requiring or not mechanical actuation control.
- the second end of the first mechanism is slidably mounted in a given direction and abuts against the first end of the second mechanism which is movable against the restoring force of an elastic member in a direction substantially co-linear with said direction. given.
- This solution allows a mechanical power transmission transmission in the given direction, for example at efforts up to 40 N, preferably between 10 and 30 N, at distances for example greater than a few cm, while being simple and reliable construction in operation.
- the elastic member allows the return to an initial position of the first end of the second mechanism when the transmission of command of the first mechanism is no longer active.

- the main spring 50 is slightly compressed and the fixed blades 21 and movable 22 of the treatment device are contacted by closing almost without pressure.
- the main spring 50 is strongly compressed and the fixed and movable blades of the treatment device are closed with pressure.
- the opening device 51 can be actuated in any adjustment position of the adjusting device 14. Because the trigger 52 and the rocker 54 are not permanently connected. , but they come to touch only when the trigger 52 is moved, the position of the latter does not change when handling the control ring 15. It should be noted that, the distance between the protrusion 49 of the trigger 52 and the pivoting end about the second pivot axis 56 of the rocker 54 varies depending on the compression state of the main spring 50, the latter being large enough to avoid permanent contact between the two. Thus, by pressing the trigger 52, the pull tab 60 is pushed backwards, it compresses the main spring 50 and allows the blades 21, 22 of the processing device 10 to open in all the positions of the control ring 15. .
- the tensile force exerted on a braid of calibrated nylon threads having a diameter of 0.6 mm close to that of the hair and placed between all the blades of the treatment device was measured using a dynamometer.

La présente invention est relative à un appareil de traitement des cheveux qui est destiné à réaliser un séchage ou une mise en forme spécifique, notamment le lissage, des cheveux d'une personne, et qui peut par ailleurs être utilisé avec un appareil généralement conçu pour le traitement des cheveux, tel un sèche-cheveux, une brosse coiffante, un fer à lisser, etc.The present invention relates to a hair treatment apparatus which is intended to carry out specific drying or shaping, in particular the smoothing, of a person's hair, and which can moreover be used with a device generally designed for hair treatment, such as a hair dryer, a styling brush, a straightener, etc.
Les méthodes généralement connues pour traiter les cheveux en vue de leur mise en forme ou leur séchage utilisent généralement de l'air chaud soufflé par un sèche-cheveux ou une application locale de chaleur et/ou de vapeur en provenance d'un dispositif à friser et/ou à lisser.The generally known methods for treating the hair for shaping or drying generally use hot air blown by a hair dryer or a local application of heat and / or steam from a curling device and / or smooth.
Les dispositifs prévus pour lisser les cheveux du type pinces à lisser comportent généralement deux mâchoires articulées chauffantes qui prennent en sandwich une mèche de cheveux et la mettent en forme en lui appliquant la chaleur. Les plaques chauffantes de ces dispositifs, même en étant revêtues de matériau céramique, sont susceptibles, à terme, d'abîmer les cheveux de par leur température élevée de fonctionnement.The devices for smoothing the hair type straighteners generally comprise two heated articulating jaws that sandwich a lock of hair and form it by applying heat. The hot plates of these devices, even while being coated with ceramic material, are likely, in the long term, to damage the hair due to their high operating temperature.

Le but de la présente invention est de remédier aux inconvénients précités en proposant un appareil de traitement des cheveux dans lequel l'actionnement de la commande d'un dispositif de traitement disposé de manière amovible à l'extrémité de l'appareil soit confortable et sûre pour l'utilisatrice, tout en conservant l'avantage d'un mécanisme protégé du contact avec les cheveux qui ne gêne pas le passage du dispositif dans les cheveux.The object of the present invention is to overcome the aforementioned disadvantages by providing a hair treatment apparatus in which the actuation of the control of a treatment device removably disposed at the end of the device is comfortable and safe. for the user, while retaining the advantage of a protected mechanism of contact with the hair that does not interfere with the passage of the device in the hair.
Un autre but de l'invention est un appareil de traitement des cheveux comportant un dispositif de traitement et un dispositif de commande des moyens de lissage pouvant être actionné de manière simple et aisée, tout en étant fiable en fonctionnement et qui soit opérationnel à tout moment, sans tenir compte de l'état de fonctionnement de l'appareil ou de celui des moyens de lissage.Another object of the invention is a hair treatment apparatus comprising a treatment device and a device for controlling the smoothing means that can be actuated simply and easily, while being reliable in operation and that is operational at all times. , irrespective of the operating state of the apparatus or that of the smoothing means.
Un autre but de l'invention est un dispositif de traitement des cheveux qui puisse assurer un lissage efficace et uniforme pour toutes les longueurs et tous les types de cheveux à traiter, tout en respectant leur nature.Another object of the invention is a hair treatment device that can ensure an effective and uniform smoothing for all lengths and all types of hair to be treated, while respecting their nature.
Un autre but de l'invention est un appareil de traitement des cheveux de construction ergonomique, qui soit d'une utilisation aisée et pratique pour la personne l'utilisant, tout en permettant un traitement rapide et efficace de la chevelure.Another object of the invention is an ergonomically constructed hair treatment apparatus that is easy and convenient to use for person using it, while allowing a fast and effective treatment of the hair.
Un autre but de l'invention est un dispositif de traitement des cheveux qui soit fiable en fonctionnement, tout en pouvant être fabriqué en grande série pour un coût moindre.Another object of the invention is a hair treatment device which is reliable in operation, while being able to be mass-produced at a lower cost.
Ces buts sont atteints avec un appareil de traitement des cheveux selon la revendication 1.These objects are achieved with a hair treatment apparatus according to
Un tel appareil est donc conçu pour produire un flux d'air chaud à l'intérieur d'un corps principal et l'envoyer en direction d'une ouverture de sortie d'air de ce corps pour passer par un dispositif de traitement des cheveux prévu à la sortie d'air de l'appareil, située à l'avant du corps de celui-ci. Le dispositif de traitement est agencé de manière amovible à la sortie d'air de l'appareil et comprend au moins un baladeur mobile par rapport au boîtier du dispositif de traitement. Un tel baladeur peut être un organe d'actionnement de volet d'obturation d'ouverture de sortie d'air du dispositif, un organe de support de peigne ou de lame se déplaçant au sein du dispositif, un organe apte à commander la distribution d'un liquide au sein du dispositif ou tout élément apte à être supporté en mouvement par le boîtier du dispositif de traitement et conçu pour recevoir une commande mécanique en provenance d'un mécanisme d'actionnement de l'appareil.Such an apparatus is therefore adapted to produce a flow of hot air within a main body and send it to an air outlet opening of that body to pass through a hair treatment device. provided at the air outlet of the device, located at the front of the body of the latter. The device treatment is removably arranged at the air outlet of the apparatus and comprises at least one movable player relative to the housing of the treatment device. Such a walkman may be an air outlet opening shutter shutter actuating member of the device, a comb or blade support member moving within the device, a member adapted to control the dispensing of the air outlet opening. a liquid within the device or any member adapted to be supported in motion by the housing of the treatment device and adapted to receive a mechanical control from an actuating mechanism of the apparatus.
Selon l'invention, le mécanisme d'actionnement comprend deux mécanismes distincts qui viennent coopérer ensemble lors de la mise en place du dispositif de traitement sur l'appareil. Ceci offre la possibilité de monter la commande d'actionnement du baladeur mobile en tout endroit approprié du corps de l'appareil, et notamment, mais pas nécessairement sur la poignée de l'appareil, tout en conservant les avantages d'un mécanisme d'actionnement distant du dispositif et protégé par le boîtier de l'appareil et d'un dispositif de traitement amovible. Ce dispositif de traitement amovible pouvant alors être remplacé par un autre dispositif ou accessoire amovible nécessitant ou pas de commande mécanique d'actionnement.According to the invention, the actuating mechanism comprises two separate mechanisms that cooperate together during the establishment of the treatment device on the device. This provides the possibility to mount the operating control of the mobile player anywhere appropriate body of the device, including, but not necessarily on the handle of the device, while retaining the advantages of a mechanism of remote actuation of the device and protected by the housing of the device and a removable treatment device. This removable treatment device can then be replaced by another device or removable accessory requiring or not mechanical actuation control.
De préférence, la deuxième extrémité du premier mécanisme est montée coulissante selon une direction donnée et vient en butée contre la première extrémité du deuxième mécanisme qui est mobile à rencontre de la force de rappel d'un organe élastique selon une direction sensiblement colinéaire à ladite direction donnée.Preferably, the second end of the first mechanism is slidably mounted in a given direction and abuts against the first end of the second mechanism which is movable against the restoring force of an elastic member in a direction substantially co-linear with said direction. given.
Cette solution permet une transmission de commande mécanique de puissance selon la direction donnée, par exemple à des efforts pouvant aller jusqu'à 40 N, de préférence compris entre 10 et 30 N, à des distances par exemple supérieures à quelques cm, tout en étant de construction simple et fiable en fonctionnement. L'organe élastique permet le retour vers une position initiale de la première extrémité du deuxième mécanisme lorsque la transmission de commande du premier mécanisme n'est plus active.This solution allows a mechanical power transmission transmission in the given direction, for example at efforts up to 40 N, preferably between 10 and 30 N, at distances for example greater than a few cm, while being simple and reliable construction in operation. The elastic member allows the return to an initial position of the first end of the second mechanism when the transmission of command of the first mechanism is no longer active.
Avantageusement, la première extrémité du deuxième mécanisme fait saillie à travers le boîtier du dispositif de traitement et pénètre dans la fenêtre de la base annulaire lorsque la commande est active.Advantageously, the first end of the second mechanism protrudes through the housing of the treatment device and enters the window of the annular base when the control is active.
Ainsi, la fenêtre de la base annulaire assure le guidage en coulissement de l'extrémité du deuxième mécanisme disposé à l'intérieur du dispositif jusque dans le boîtier du corps de l'appareil pour une meilleure mise en correspondance garantissant une transmission de commande sûre entre les deux mécanismes.Thus, the window of the annular base slidably guides the end of the second mechanism disposed inside the device into the housing of the body of the device for better matching ensuring a secure control transmission between both mechanisms.
De préférence, ladite direction est parallèle à celle de l'axe longitudinal du corps principal de l'appareil.Preferably, said direction is parallel to that of the longitudinal axis of the main body of the apparatus.
Un tel déplacement de l'extrémité du mécanisme selon une direction longitudinale est réalisé avantageusement en logeant le mécanisme et sa tige d'actionnement dans le corps principal tubulaire de l'appareil, parallèlement à l'une des ses parois internes. Un tel mécanisme s'avère de construction compacte, il n'augmente pas l'encombrement de l'appareil et n'accroche pas les cheveux à traiter.Such a displacement of the end of the mechanism in a longitudinal direction is advantageously achieved by housing the mechanism and its actuating rod in the tubular main body of the apparatus, parallel to one of its internal walls. Such a mechanism is compact construction, it does not increase the size of the device and does not catch the hair to treat.
Avantageusement, le dispositif de traitement comporte au moins deux éléments de lissage en vis-à-vis coopérant pour pincer une mèche de cheveux et ladite commande est conçue pour modifier le jeu et/ou la force de serrage entre les éléments de lissage.Advantageously, the treatment device comprises at least two smoothing elements vis-à-vis cooperating to pinch a lock of hair and said control is designed to change the play and / or the clamping force between the smoothing elements.
Par éléments de lissage coopérant pour pincer une mèche de cheveux, on comprend des éléments de lissage comprenant des moyens aptes à exercer une pression sur les cheveux insérés entre deux éléments en vis-à-vis. Une telle pression peut être engendrée en utilisant un dispositif élastique, un dispositif magnétique, un dispositif pneumatique, etc. destiné à pousser les éléments de lissage l'un vers l'autre au contact des cheveux. L'appareil comprend un dispositif de déplacement des éléments de lissage de l'état ouvert à l'état fermé ou vice-versa (par état ouvert on comprend que les éléments sont écartés de manière à ce que les cheveux puissent être introduits entre deux éléments en vis-à-vis). L'appareil comporte par ailleurs un dispositif de réglage de la force de pression exercée sur les cheveux à traiter par les éléments de lissage lorsqu'ils sont à l'état fermé afin de l'adapter à différents types de cheveux et/ou aux sensibilités des utilisatrices.By smoothing elements cooperating to pinch a lock of hair, smoothing elements comprising means capable of exerting pressure on the hair inserted between two elements vis-à-vis. Such pressure can be generated by using an elastic device, a magnetic device, a pneumatic device, etc. intended to push the smoothing elements towards each other in contact with the hair. The apparatus comprises a device for moving the smoothing elements of the open state in the closed state or vice versa (by open state it is understood that the elements are spaced apart so that the hair can be introduced between two elements vis-à-vis). The apparatus also comprises a device for adjusting the pressure force exerted on the hair to be treated by the smoothing elements when they are in the closed state in order to adapt it to different types of hair and / or sensitivities. users.
De préférence, ledit premier mécanisme comprend une tirette reliée à un dispositif de déplacement des éléments de lissage et à un dispositif de réglage de la force de serrage des éléments de lissage agencés l'un dans le prolongement de l'autre en étant reliés par un ressort de compression.Preferably, said first mechanism comprises a pull rod connected to a device for moving the smoothing elements and to a device for adjusting the clamping force of the smoothing elements arranged one in the extension of the other and connected by a compression spring.
Ceci permet d'agencer les deux dispositifs dans le boîtier ou corps principal de l'appareil, en amont du dispositif de traitement, ce qui a pour avantage d'obtenir un appareil compact et de dégager la zone de traitement des cheveux avoisinant le dispositif de lissage de tout dispositif ou pièce qui pourrait accrocher les cheveux. Le ressort de compression agit comme un couplage permettant de relier fonctionnellement les deux commandes, celle de déplacement et celle de réglage de la pression entre les éléments de pincement.This makes it possible to arrange the two devices in the housing or main body of the device, upstream of the treatment device, which has the advantage of obtaining a compact device and of clearing the treatment zone of the hair adjacent to the device of the device. smoothing any device or piece that could hang the hair. The compression spring acts as a coupling to functionally connect the two controls, that of movement and that of adjusting the pressure between the clamping elements.
Le dispositif de déplacement est actionné par une gâchette appartenant à la poignée de l'appareil.The displacement device is actuated by a trigger belonging to the handle of the apparatus.
Ceci permet un actionnement aisé de l'appareil, notamment de son dispositif de déplacement des éléments de lissage, l'utilisatrice utilisant la même main qui tient l'appareil par la poignée pour actionner la gâchette.This allows easy operation of the device, including its device for moving the smoothing elements, the user using the same hand that holds the device by the handle to actuate the trigger.
De préférence, ladite gâchette est montée articulée en pivotement autour d'un axe horizontal de la poignée et entraîne la tirette (60) moyennant deux bras articulés intermédiaires.Preferably, said trigger is mounted hingedly pivoted about a horizontal axis of the handle and drives the pull tab (60) by means of two intermediate articulated arms.
On aurait pu, certes, utiliser une gâchette à mouvement coulissant horizontal (ou parallèle au flux d'air soufflé par l'appareil). Toutefois, on préfère un montage pivotant de la gâchette qui permet, moyennant les bras articulés intermédiaires, d'obtenir un déplacement longitudinal de la tirette, pour un effort et un déplacement moindres à l'actionnement de la gâchette.It would have been possible, of course, to use a trigger with horizontal sliding movement (or parallel to the flow of air blown by the device). However, it is preferred a pivoting mounting of the trigger which allows, by means of the intermediate articulated arms, to obtain a longitudinal displacement of the zipper, for less effort and less movement when actuating the trigger.
Avantageusement, ledit dispositif de réglage comporte une bague de commande conçue pour tourner autour de l'axe longitudinal du corps principal de l'appareil agencée dans la proximité de l'ouverture d'entrée d'air du corps principal de forme générale cylindrique de l'appareil et comprend un organe de réglage à mouvement linéaire qui est conçu pour varier la force de serrage entre les éléments de lissage lorsque la bague de commande est animée d'un mouvement de rotation.Advantageously, said adjusting device comprises a control ring designed to rotate about the longitudinal axis of the main body of the apparatus arranged in the vicinity of the air intake opening of the main body of generally cylindrical shape of the apparatus and comprises a linear motion adjusting member which is adapted to vary the clamping force between the smoothing members when the control ring is rotated.
Ainsi, en tournant la bague de commande du dispositif de réglage autour de l'axe longitudinal du flux d'air, on fait varier la force de pression sur la mèche afin de l'adapter à l'opération de lissage souhaitée en fonction du type et/ou de l'état des cheveux à traiter, de manière continue ou intermittente, et ceci avec un dispositif de réglage comportant une pièce de commande facilement manipulable, la personne l'utilisant pouvant alors, d'une main, tenir l'appareil dirigé vers la chevelure et, de l'autre main, faire varier de manière intuitive la force de serrage, sans effort et sans devoir regarder l'appareil de près. On préfère toutefois un agencement à l'arrière du corps, car, d'une part c'est l'endroit le plus éloigné de la chevelure et il n'y a donc pas d'accrochage de cheveux possible avec la bague de commande et, d'autre part, la bague peut ainsi tourner, à l'intérieur ou à l'extérieur du corps de forme générale cylindrique de l'appareil, dans une zone dégagée de celui-ci où elle n'interfère pas avec d'autres composants fonctionnels de l'appareil, tels le ventilateur, l'élément chauffant, etc.Thus, by rotating the control ring of the adjusting device around the longitudinal axis of the air flow, the pressure force is varied on the wick in order to adapt it to the desired smoothing operation depending on the type and / or the state of the hair to be treated, continuously or intermittently, and this with an adjusting device comprising a control part easily manipulated, the person using it can then, with one hand, hold the device directed to the hair and, with the other hand, to intuitively vary the clamping force, without effort and without having to look closely at the apparatus. However, an arrangement is preferred at the back of the body, because, on the one hand, it is the furthest place from the hair and therefore there is no hair catching possible with the control ring and on the other hand, the ring can thus rotate, inside or outside the body of cylindrical general shape of the apparatus, in an open area thereof where it does not interfere with other functional components of the device, such as the fan, the heating element, etc.
Ainsi, l'organe de commande peut être directement entraîné en translation en coopérant avec un moyen d'actionnement adjacent, par exemple une came, la spire d'une vis, ou toute autre pièce complémentaire apte à transformer directement le mouvement de rotation autour de l'axe longitudinal du flux d'air de la bague de commande en un mouvement linéaire par exemple, parallèlement à l'axe du flux d'air de l'organe de commande agissant alors sur les éléments de lissage. Un tel mouvement rotatif d'une bague de commande de grand diamètre permet alors de démultiplier le déplacement linéaire de l'organe de commande et d'obtenir ainsi un réglage fin de la pression de serrage des éléments de lissage.Thus, the control member can be directly driven in translation by cooperating with an adjacent actuating means, for example a cam, the turn of a screw, or any other complementary piece able to directly transform the rotational movement around the longitudinal axis of the airflow of the control ring in a linear movement for example, parallel to the axis of the air flow of the control member then acting on the smoothing elements. Such a rotary movement of a large-diameter control ring then makes it possible to reduce the linear displacement of the control member and thus to obtain a fine adjustment of the clamping pressure of the smoothing elements.
De préférence, les éléments de lissage sont normalement fermés en étant poussés l'un contre l'autre par la force d'un moyen élastique et ledit dispositif de déplacement est un dispositif d'ouverture des éléments de lissage.Preferably, the smoothing elements are normally closed by being pushed against each other by the force of an elastic means and said displacement device is a device for opening the smoothing elements.
Les éléments de lissage sont normalement fermés à l'état de repos, tout en étant munis chacun de moyens d'introduction automatique des mèches de cheveux, les mèches écartant ainsi les éléments de lissage en s'introduisant à l'intérieur de ceux-ci, pour une utilisation aisée et intuitive de l'appareil. L'appareil muni d'un tel dispositif de lissage est passé dans les cheveux qui écartent alors naturellement les éléments de lissage et permettent à l'appareil d'effectuer un traitement à partir de la racine des cheveux en allant jusqu'au bout de la mèche traitée qui s'extrait ensuite toute seule du dispositif.The smoothing elements are normally closed in the state of rest, while each being provided with means for automatically introducing the locks of hair, the locks thus removing the smoothing elements by being introduced inside them , for an easy and intuitive use of the device. The device provided with such a smoothing device is passed through the hair which then naturally spread the smoothing elements and allow the device to perform a treatment from the hair root to the end of the treated wick which is then extracted alone from the device.
Selon un autre mode de réalisation, les éléments de lissage sont normalement ouverts en étant écartés l'un de l'autre par la force d'un moyen de rappel et le premier mécanisme est un mécanisme de fermeture des éléments de lissage.According to another embodiment, the smoothing elements are normally open while being separated from each other by the force of a return means and the first mechanism is a closing mechanism of the smoothing elements.
Cette disposition permet d'introduire facilement les mèches de cheveux entre les éléments de lissage, ces derniers étant écartés et de les fermer à l'aide du premier mécanisme. Dans ce mode de réalisation, la pression exercée sur les cheveux à traiter par les éléments de lissage lorsqu'ils sont à l'état fermés est proportionnelle à la force exercée par la personne sur le premier mécanisme. Ainsi, la personne peut corriger les variations de pression entre le début du traitement où les mèches sont plus grosses et la fin de traitement où les extrémités des mèches sont plus petites. En effet, dans le mode de réalisation où les éléments de lissage sont normalement fermés, la pression en début de traitement sur les cheveux est plus élevée, les éléments de lissage étant plus écartés par les mèches, qu'en fin de traitement où les éléments de lissage sont très rapprochés, les extrémités des mèches étant plus petites.This arrangement makes it possible to easily introduce the locks of hair between the smoothing elements, the latter being removed and to close them with the aid of the first mechanism. In this embodiment, the pressure exerted on the hair to be treated by the smoothing elements when in the closed state is proportional to the force exerted by the person on the first mechanism. Thus, the person can correct the pressure variations between the beginning of treatment where the locks are larger and the end of treatment where the ends of the locks are smaller. Indeed, in the embodiment where the smoothing elements are normally closed, the pressure at the beginning of treatment on the hair is higher, the smoothing elements are further apart by the locks at the end of treatment where the smoothing elements are very close together, the ends of the locks being smaller.
Ledit premier mécanisme comprend une gâchette montée pivotante dans la poignée, munie d'un poussoir apte à faire coulisser une tige vers l'avant lors d'un appui sur ladite gâchette.Said first mechanism comprises a trigger pivotally mounted in the handle, provided with a pusher able to slide a rod forward when pressing on said trigger.
Ceci permet d'agencer le premier mécanisme dans le boîtier ou corps principal de l'appareil, en amont du dispositif de traitement, ce qui a pour avantage d'obtenir un appareil compact et de dégager la zone de traitement des cheveux avoisinant le dispositif de lissage de tout dispositif ou pièce qui pourrait accrocher les cheveux.This makes it possible to arrange the first mechanism in the housing or main body of the apparatus, upstream of the treatment device, which has the advantage of obtaining a compact apparatus and of clearing the treatment zone of the hair adjacent to the device of smoothing any device or piece that could hang the hair.
Avantageusement, les éléments de lissage sont formés d'une lame fixe et d'une lame mobile supportée par le baladeur, la lame mobile étant montée sur le baladeur sous la poussée d'un premier ressort de rappel.Advantageously, the smoothing elements are formed of a fixed blade and a movable blade supported by the player, the movable blade being mounted on the player under the thrust of a first return spring.
On aurait pu, certes, utiliser deux éléments de lissage mobiles que l'on aurait déplacé pour passer de l'état ouvert à l'état fermé ou vice-versa après l'introduction d'une mèche de cheveux entre les deux. On préfère toutefois, pour des raisons de simplicité constructive, rendre mobile l'un des éléments de lissage en le montant sur un baladeur ou tige qui peut alors, lorsqu'il est actionné, entraîner l'élément mobile. La forme de lame des éléments de lissage permet un lissage à plat, lors d'un contact contre un plan des cheveux traités, ce qui permet de réaliser une bonne mise en forme de la mèche de cheveux, sans toutefois lui appliquer une contrainte trop importante. Une possibilité de déplacement supplémentaire de la lame mobile est offerte en la montant sur le baladeur à l'encontre de la force d'un ressort de rappel. Ceci permet une meilleure adaptation à l'épaisseur de la mèche introduite entre les éléments de lissage par compression du ressort de rappel lorsque la mèche prend appui contre une lamé fixe adjacente.It would have been possible, of course, to use two mobile smoothing elements that one would have moved to move from the open state to the closed state or vice versa after the introduction of a lock of hair between the two. However, for reasons of constructive simplicity, it is preferable to make one of the smoothing elements movable by mounting it on a walkman or rod which can then, when actuated, drive the movable element. The blade shape of the smoothing elements allows a flat smoothing, during a contact against a plane of the treated hair, which allows a good shaping of the lock of hair, without however apply a too important constraint . A possibility of additional displacement of the movable blade is offered by mounting it on the player against the force of a return spring. This allows a better adaptation to the thickness of the wick introduced between the elements of smoothing by compression of the return spring when the wick bears against an adjacent fixed lamina.
De préférence, le baladeur est monté moyennant un deuxième ressort de rappel dans le boîtier du dispositif de traitement.Preferably, the player is mounted by means of a second return spring in the housing of the treatment device.
Ceci permet d'avoir un actionnement dans un sens du baladeur par la deuxième extrémité du deuxième mécanisme, le retour se faisant sous la poussée du deuxième ressort de rappel, pour une solution constructive simplifiée et économique des moyens d'actionnement du baladeur.This makes it possible to have an actuation in one direction of the walkman by the second end of the second mechanism, the return being done under the thrust of the second return spring, for a simplified and economical constructive solution of the drive means of the player.
Avantageusement, le dispositif de traitement comporte une rangée de plusieurs paires de lames fixes et mobiles montées côte à côte transversalement à l'axe dudit baladeur.Advantageously, the processing device comprises a row of several pairs of fixed and movable blades mounted side by side transversely to the axis of said player.
Un tel dispositif de lissage comportant par exemple une rangée de sept paires d'éléments de lissage permet de traiter plusieurs mèches simultanément offrant ainsi une efficacité accrue et un gain de temps considérable du traitement de la chevelure, l'appareil restant toutefois d'une utilisation très aisée.Such a smoothing device comprising, for example, a row of seven pairs of smoothing elements makes it possible to treat several strands simultaneously, thus offering increased efficiency and a considerable time saving in the treatment of the hair, the apparatus nevertheless remaining of use. very easy.
De préférence, ladite rangée est agencée au centre de l'ouverture de sortie d'air et une rangée de picots est agencée de chaque côté de la rangée d'éléments de lissage, en retrait par rapport à la partie d'attaque de ceux-ci.Preferably, said row is arranged in the center of the air outlet opening and a row of pins is arranged on each side of the row of smoothing elements, set back from the attacking portion of these this.
La rangée d'éléments de lissage étant placée au centre de l'ouverture de sortie d'air, les éléments de lissage bénéficient de l'air soufflé par l'appareil qui peut arriver soit à leur base, soit au niveau de leurs flancs latéraux, soit à la base et au niveau de leurs flancs latéraux pour une mise en forme plus rapide et plus efficace de la chevelure. Les rangées de picots permettent de mieux saisir les cheveux et les guider dans l'intervalle défini entre deux éléments de lissage. Par ailleurs, de par leur agencement en retrait par rapport à la partie d'attaque ou frontale des éléments de lissage, ces derniers sont ainsi aptes à venir les premiers au contact des cheveux, notamment les plus courts permettant ainsi leur insertion entre les éléments de lissage, sans que ces cheveux courts ne soient obligés de passer par les picots. Cet agencement en retrait des picots permet donc le lissage des cheveux très courts, le profil de la partie d'attaque des lames fixes et des lames mobiles présentant des pentes favorisant la prise des cheveux au plus près de la racine et ensuite leur insertion entre les lames fixes et mobiles.The row of smoothing elements being placed in the center of the air outlet opening, the smoothing elements benefit from the air blown by the apparatus which can arrive either at their base or at their lateral flanks. , at the base and at their side flanks for a faster and more effective shaping of the hair. The rows of pins make it possible to better grasp the hair and guide it in the interval defined between two smoothing elements. Moreover, by their arrangement set back with respect to the leading or front part of the smoothing elements, the latter are thus able to come first in contact with the hair, in particular the shorter ones, thus allowing their insertion between the elements of the hair. smoothing, without these short hair being forced to go through the pins. This arrangement in withdrawal of the pins therefore allows the smoothing of very short hair, the profile of the attacking part fixed blades and movable blades with slopes promoting hair grip closer to the root and then their insertion between the fixed blades and movable.
Avantageusement, les lames mobiles se déplacent dans une direction transversale à celle du flux d'air soufflé par l'appareil.Advantageously, the movable blades move in a direction transverse to that of the flow of air blown by the apparatus.
Ceci permet d'insérer la mèche à traiter selon une direction perpendiculaire au flux d'air soufflé par l'appareil afin qu'elle bénéficie pleinement sur sa longueur de l'arrivée frontale du flux d'air.This makes it possible to insert the wick to be treated in a direction perpendicular to the flow of air blown by the apparatus so that it fully benefits over its length from the frontal arrival of the air flow.
De préférence, le deuxième mécanisme comprend une tirette secondaire reliée par un levier au baladeur.Preferably, the second mechanism comprises a secondary zipper connected by a lever to the player.
La tirette secondaire se déplaçant parallèlement au flux d'air permet son agencement selon l'une des parois du boîtier du dispositif amovible, dans le prolongement du corps principal de l'appareil de forme générale tubulaire, sans augmenter l'encombrement de celui-ci. Le levier forme un organe de renvoi assurant la transmission du mouvement de commande aux éléments de lissage à déplacement transversal au flux d'air.The secondary zipper moving parallel to the air flow allows its arrangement along one of the walls of the housing of the removable device, in the extension of the main body of the generally tubular device, without increasing the bulk thereof . The lever forms a return member ensuring the transmission of the control movement to the smoothing elements moving transversely to the air flow.

L'appareil de traitement des cheveux représenté aux figures annexées 1 à 3b est du type sèche-cheveux 1 muni d'un dispositif de traitement 10. Le sèche-cheveux 1 comprend un corps principal 3 tubulaire, de forme générale cylindrique, renfermant un ventilateur actionné par un moteur électrique (non représentés sur les dessins) et agencés pour produire un flux d'air orienté selon l'axe longitudinal 2 du corps principal 3 de l'appareil entre une extrémité d'entrée d'air 4 et une extrémité de sortie d'air 5. L'appareil comprend également un élément chauffant électrique (non représenté sur les dessins) agencé dans le corps principal 3 en amont de l'orifice de sortie d'air. Le corps principal 3 est prolongé vers le bas par une poignée 6 de préhension renfermant la partie électrique de commande et de connexion de l'appareil à l'alimentation, la poignée 6 étant munie par ailleurs de boutons de commande et de sélection du mode de fonctionnement, notamment de réglage du débit d'air soufflé, de la température de l'appareil, etc.. Le corps principal 3 et la poignée 6 sont réalisés en assemblant, selon un plan vertical, deux coques 7 symétriques (pour des soucis de clarté, uniquement une seule coque étant représentée sur les dessins) réalisées en une matière plastique par une technique d'injection.The hair treatment apparatus shown in the accompanying figures 1 to 3b is of the

Les voûtes 33 ont un profil général triangulaire, leur rebord externe ou partie d'attaque présentant des pentes 35 inclinées chacune (par exemple faisant un angle de 30 à 40° avec un plan médian passant par leur sommet) en direction d'un interstice 34 voisin. Cette inclinaison des rebords des voûtes 33 permet de guider et de faciliter l'insertion des cheveux dans un interstice 34. A l'intérieur, chaque voûte 33 présente une paroi interne formant lame fixe 21, une niche 44 étant prévue derrière cette paroi, au sein de la voûte 33. (

Le baladeur 23 est une tige cylindrique comportant une première extrémité 38 tenue par un flasque 39, l'extrémité opposée 40 étant tenue, elle, par une fourche 41 (
Selon l'invention, l'appareil comprend deux mécanismes distincts d'actionnement du baladeur 23, un premier mécanisme 71 agencé dans le corps principal 3 de l'appareil et un deuxième mécanisme 75 agencé dans le boîtier 27 du dispositif de traitement 10.According to the invention, the apparatus comprises two distinct mechanisms for actuating the
Le premier mécanisme 71 comprend un dispositif de déplacement des éléments de pincement qui, dans l'exemple représenté aux dessins, est un dispositif d'ouverture 51 des éléments de lissage 11,12 relié à un dispositif de réglage 14 de la force de serrage des éléments de lissage 11,12.The
Le dispositif de réglage 14 de la force de serrage des éléments de lissage 11,12 appartient au corps principal 3 de l'appareil et comporte une bague de commande 15 agencée à l'extrémité d'entrée d'air 4 dans le corps principal 3 de l'appareil. La bague 15 a une forme générale annulaire comportant un rebord strié 45 faisant saillie à l'extérieur du corps principal 3 de l'appareil et une partie interne nervurée située à l'intérieur du corps principal 3. La partie interne nervurée comprend une nervure circulaire 46 de guidage en rotation autour de l'axe longitudinal 2 du corps principal 3 de l'appareil et une deuxième nervure 47 concentrique et d'un même diamètre que la première. La deuxième nervure 47 comporte une rampe hélicoïdale 18 protubérante vers l'intérieur du corps 3, rampe qui, dans l'exemple représenté aux figures, s'étend sur environ un quart de la circonférence de la nervure 47. La rampe hélicoïdale 18 vient au contact d'un ergot 19 d'un organe de réglage 17. Dans l'exemple représenté aux figures, pour réduire le frottement avec la rampe 18, l'ergot 19 est remplacé par un galet qui tourne autour d'un axe vertical (perpendiculaire à l'axe longitudinal du corps 3). Tel que mieux visible à la
Les lames fixes 21 et mobiles 22 se trouvent normalement fermées, leurs surfaces de traitement étant au contact l'une de l'autre (on comprend l'état du dispositif au repos, le dispositif étant monté sur l'appareil et aucun organe de commande n'étant actionné). Le dispositif d'ouverture 51 comporte un mécanisme d'ouverture à plusieurs bras articulés actionné depuis la poignée 6 par une gâchette 52. La gâchette 52 est montée rotative autour d'un premier axe de pivotement 53, un ressort de torsion (non représenté aux dessins) étant prévu pour assurer le retour de la gâchette dans sa position de repos. L'axe de pivotement 53 est transversal à l'axe longitudinal 2 du corps principal 3 de l'appareil. La gâchette 52 comporte une protubérance 49 sur son côté interne opposé à celui externe d'appui. Un basculeur 54 est un bras doublement articulé monté rotatif à l'une de ses extrémités autour du premier axe de pivotement 53 et à l'extrémité opposée autour d'un deuxième axe de pivotement 56, parallèle à l'axe 53. Une biellette 55 est montée également doublement articulée en rotation autour du deuxième axe de pivotement 56 à l'une de ses extrémités et autour d'un troisième axe de pivotement 57, parallèle à l'axe 56, à l'extrémité opposée.The fixed
Le dispositif d'ouverture 51 comporte par ailleurs une tirette 60 comportant une partie avant formant une tige longitudinale 59 prolongée à l'arrière par une première extrémité 58 comportant des rails de guidage 61 dans une glissière prévue à cet effet dans le corps principal 3 de appareil et agencée parallèlement à l'axe longitudinal 2 de celui-ci. La première extrémité 58 est alignée avec le ressort 50 et donc avec l'organe de réglage 17, l'extrémité arrière de la première extrémité 58 venant prendre appui sur le ressort hélicoïdal 50. L'extrémité arrière de la tirette 60 comporte par ailleurs un bras inférieur 65 parallèle à l'axe longitudinal de la tige 59 en étant décalé vers le bas, en direction de la poignée, l'extrémité arrière du bras inférieur 65 étant montée sur le troisième axe de pivotement 57. La tige 59 de la tirette 60 se termine par une deuxième extrémité 66 à bout arrondi. A titre d'exemple, l'effort de compression mesuré à l'extrémité de la tirette 60 est situé entre 2,7 N/mm et 3,7 N/mm.The
Le deuxième mécanisme 75 comporte une première extrémité formée par une première extrémité 67 d'une tirette secondaire 62 et une deuxième extrémité constituée par la fourche 41 supportant le baladeur 23. La fourche 41 a une forme de U, les deux branches parallèles comportant au centre une encoche interne dans laquelle s'introduit le bras d'un levier coudé 63, tel qu'il sera expliqué par la suite.The
La deuxième extrémité 66 de la tirette 60 vient au contact de la tirette secondaire 62 appartenant au boîtier 27 du dispositif de traitement 10. La tirette secondaire 62 a une forme allongée, de section transversale ovale, et est munie de rails de guidage 77 dans lesquels coulissent des nervures réalisées à l'intérieur du boîtier 27 (non visibles sur les dessins). La première extrémité 67 de la tirette secondaire 62 est amenée à traverser une fenêtre 78 de forme ovale pratiquée dans la base annulaire 31 réalisée à la sortie du corps principal 3 de l'appareil. La première extrémité 67 comporte au centre une empreinte en creux dans laquelle prend contact la deuxième extrémité 66 de la tirette 60. La tirette secondaire 62 comporte également une deuxième extrémité 76 à bout arrondi qui, elle, vient au contact du bras inférieur 68 d'un levier 63 monté pivotant autour d'un axe 64 surélevé agencé selon une direction parallèle aux lames fixes 21 et mobiles 22 (ou transversal à l'axe du baladeur 23). Le levier 63 comporte deux bras supérieurs 70 faisant un angle d'environ 90° avec le bras inférieur 68 et prenant appui dans des encoches internes de la fourche 41 supportant le baladeur 23.The
Le fonctionnement du dispositif d'ouverture sera maintenant décrit plus particulièrement en référence à la
A l'inverse, lorsque la gâchette 52 est relâchée, celle-ci revient en position initiale sous la poussée d'un ressort de torsion agencé autour de l'axe de pivotement de la gâchette 52, la tirette 60 étant alors poussée vers l'avant par la force du ressort 50 qui est supérieure à celle du deuxième ressort de rappel 25 qui est ainsi comprimé. Les lames mobiles 22 se retrouvent ainsi au contact des lames fixes 21, la commande étant transmise depuis le corps de l'appareil par la tirette 60 venant en butée contre la tirette secondaire 62.Conversely, when the
Le fonctionnement du dispositif de réglage sera maintenant décrit plus particulièrement en référence à la
En position de réglage minimum, le ressort principal 50 est peu comprimé et les lames fixes 21 et mobiles 22 du dispositif de traitement se touchent en se fermant quasiment sans pression.In the minimum adjustment position, the
En position de réglage maximum, le ressort principal 50 est fortement comprimé et les lames fixes et mobiles du dispositif de traitement sont fermées avec pression.In the maximum setting position, the
Selon un aspect avantageux de l'invention, le dispositif d'ouverture 51 peut être actionné dans n'importe quelle position d'ajustement du dispositif de réglage 14. Du fait que la gâchette 52 et le basculeur 54 ne sont pas connectés de manière permanente, mais ils viennent se toucher uniquement lors du déplacement de la gâchette 52, la position de cette dernière ne change pas lors de la manipulation de la bague de commande 15. Il faut remarquer que, la distance entre la protubérance 49 de la gâchette 52 et l'extrémité pivotante autour du deuxième axe de pivotement 56 du basculeur 54 varie en fonction de l'état de compression du ressort principal 50, celle-ci étant suffisamment importante pour éviter un contact permanent entre les deux. Ainsi, en appuyant sur la gâchette 52, la tirette 60 est poussée vers l'arrière, elle comprime le ressort principal 50 et permet l'ouverture des lames 21, 22 du dispositif de traitement 10 dans toutes les positions de la bague de commande 15.According to an advantageous aspect of the invention, the
A titre d'exemple, des mesures de force de serrage sur les cheveux ont été effectuées au laboratoire. Ainsi, on a mesuré à l'aide d'un dynamomètre la force de traction exercée sur une tresse de fils de nylon calibrés ayant un diamètre de 0.6 mm proche de celui des cheveux et placée entre toutes les lames du dispositif de traitement. Ainsi, avec le dispositif de réglage de l'invention, la force de traction sur la tresse expérimentale peut varier entre 180g et 640g pour un déplacement d'un quart de tour de la bague de commande 15. Des réglages plus fins peuvent être réalisés en modifiant la forme et/ou les dimensions de la rampe de la bague de commande 15.As an example, clamping force measurements on the hair have been performed in the laboratory. Thus, the tensile force exerted on a braid of calibrated nylon threads having a diameter of 0.6 mm close to that of the hair and placed between all the blades of the treatment device was measured using a dynamometer. Thus, with the adjusting device of the invention, the tensile force on the experimental braid can vary between 180g and 640g for a shift of a quarter turn of the

Le dispositif de traitement 110 est agencé à l'extrémité formant sortie d'air 105 du corps principal 103 de l'appareil et comprend au moins deux éléments de lissage 111,112 constitués par une pluralité de lames fixes 121 et une pluralité de lames mobiles 122 se faisant face et coopérant pour pincer une mèche de cheveux.The
Un boîtier 127 présente une partie avant réalisée par une succession de voûtes 133, par exemple 7 voûtes. A l'intérieur, chaque voûte 133 présente une paroi formant lame fixe 121. La rangée de voûtes 133 est disposée en la partie centrale du boîtier 127 du dispositif de traitement 110, deux ouvertures latérales 136 de sortie d'air étant prévues de part et d'autre de la rangée de voûtes 133.Par ailleurs, une rangée de picots 129 est fixée à la base de la rangée de voûtes 133, de part et d'autre de cette dernière.A
Le boîtier 127 du dispositif de traitement 110 supporte à ses extrémités un baladeur 123 supportant à son tour les lames mobiles 122. Chaque lame mobile est montée sur le baladeur 123 sous la contrainte d'un premier ressort de rappel 124, par exemple un ressort de compression. Une rangée de lames mobiles 122 est réalisée en empilant sur le baladeur 123 le premier ressort de rappel 124 fixé à l'une de ses extrémités par une rondelle 126 sur le baladeur 123, l'autre extrémité du ressort venant prendre appui sur une lame mobile 122, suivi d'un autre ressort 124 et d'une lame mobile 122, et ainsi de suite jusqu'à compléter la rangée de lames mobiles 122, par exemple sept lames mobiles 122 parallèles entre elles.The
Le baladeur 123 est une tige cylindrique comportant une première extrémité tenue par un flasque 139, l'extrémité opposée étant tenue, elle, par une fourche 141. Le baladeur 123 est monté avec une possibilité de déplacement le long de son axe longitudinal sous la poussée d'un ressort de rappel 125 monté entre sa première extrémité et le flasque 139. Lorsque le baladeur 123 est monté à l'intérieur du boîtier 127 du dispositif de traitement 110, les lames mobiles 122 viennent s'insérer entre les lames fixes 121. Le dispositif de traitement 110 comporte ainsi une rangée 128 de plusieurs paires de lames fixes 121 et mobiles 122 montées côte à côte perpendiculairement à l'axe du baladeur 123, rangée agencée au centre d'une ouverture 108 de sortie d'air de l'appareil.The
Les lames fixes 121 et mobiles 122 se trouvent normalement ouvertes, leurs surfaces de traitement étant écartées l'une de l'autre sous la poussée du ressort de rappel 125 (on comprend l'état du dispositif au repos, le dispositif étant monté sur l'appareil et aucun organe de commande n'étant actionné).The fixed and
Selon l'invention, l'appareil comprend deux mécanismes distincts d'actionnement du baladeur 123, un premier mécanisme 171 agencé dans le corps principal 103 de l'appareil et un deuxième mécanisme 175 agencé dans le boîtier 127 du dispositif de traitement 110.According to the invention, the apparatus comprises two distinct mechanisms for actuating the
Le premier mécanisme 171 comporte une gâchette 152, montée rotative autour d'un axe de pivotement 153. L'axe de pivotement 153 est transversal à l'axe longitudinal 102 du corps principal 103 de l'appareil. La gâchette comporte par ailleurs un poussoir 160 coopérant avec une première extrémité 158 d'une tige 159 longitudinale guidée dans le corps principal 103 de l'appareil et agencée parallèlement à l'axe longitudinal 102 de celui-ci. La tige 159 se termine par une deuxième extrémité 166 à bout arrondi. Un ressort de rappel 150 est agencé sur la tige 159.The
Le deuxième mécanisme 175 comporte une première extrémité formée par une première extrémité 167 d'une tirette secondaire 162 et une deuxième extrémité constituée par la fourche 141 supportant le baladeur 123. La fourche 141 a une forme de U, les deux branches parallèles comportant au centre une encoche interne dans laquelle s'introduit le bras d'un levier coudé 163.The
La deuxième extrémité 166 de la tige 159 vient au contact de la tirette secondaire 162 appartenant au boîtier 127 du dispositif de traitement 110. La tirette secondaire 162 coulisse à l'intérieur du boîtier 127. La première extrémité 167 de la tirette secondaire 162 est amenée à traverser une fenêtre 178 pratiquée dans la base annulaire 131 réalisée à la sortie du corps principal 103 de l'appareil. La première extrémité 167 comporte au centre une empreinte en creux dans laquelle prend contact la deuxième extrémité 166 de la tige 159. La tirette secondaire 162 comporte également une deuxième extrémité 176 à bout arrondi qui, elle, vient au contact d'un bras inférieur du levier 163 monté pivotant autour d'un axe surélevé agencé selon une direction parallèle aux lames fixes 121 et mobiles 122 (ou transversal à l'axe du baladeur 123). Les deux bras supérieurs font un angle d'environ 90° avec les bras inférieurs.The
En fonctionnement, lorsque l'utilisatrice actionne la gâchette 152 vers l'intérieur de la poignée 106, la gâchette 152 tourne autour de l'axe de pivotement 153 et le poussoir 160 fait coulisser la tige 159 vers l'avant selon une direction parallèle à celle de l'axe longitudinal 102 du corps 103 de l'appareil. La tirette secondaire 162 se déplace alors également vers l'avant, provoquant la fermeture des lames mobiles 122 contre les lames fixes 121 adjacentes.In operation, when the user actuates the
A l'inverse, lorsque la gâchette 152 est relâchée, celle-ci revient en position initiale sous la poussée du ressort 150 via la tige 159. Le ressort de rappel 125 pousse le baladeur 123 écartant ainsi les lames mobiles 122 des lames fixes 121.Conversely, when the
D'autres variantes et modes de réalisation de l'invention peuvent être envisagés sans sortir du cadre de ces revendications.Other variants and embodiments of the invention may be envisaged without departing from the scope of these claims.
Ainsi, on peut remplacer la poussée à l'encontre du moyen de rappel élastique entre les deux mécanismes en réalisant la coopération entre les deux mécanismes 71, 75 par une fixation réversible de la deuxième extrémité 66 du premier mécanisme 71 avec la première extrémité 67 du deuxième mécanisme 75, par exemple avec un engagement à frottement doux ou par attraction magnétique. Toutefois, la coopération entre ces deux extrémités doit être réalisée automatiquement lorsque le dispositif de traitement est monté sur l'appareil.Thus, it is possible to replace the thrust against the elastic return means between the two mechanisms by effecting the cooperation between the two
Par ailleurs, la commande est réalisée sous forme d'une gâchette 52 placée sur la poignée 6, mais il est possible de la réaliser également sous forme d'un bouton poussoir monté sur le corps principal 3 de l'appareil.Furthermore, the control is performed in the form of a
