DESCRIPCIONDESCRIPTION

Depiladora isostatica con pinzas pivotantesIsostatic epilator with pivoting clamps

El presente invento se refiere al campo tecnico de los aparatos de cuidado corporal que utilizan un cabezal de cuidado mecanico accionada por un motor electrico y especialmente al campo de los aparatos de depilacion 5 mecanica utilizados para el arranque de los pelos.The present invention relates to the technical field of body care devices that use a mechanical care head driven by an electric motor and especially to the field of mechanical hair removal devices 5 used to start hairs.

En el campo citado anteriormente ya se conocen aparatos de depilacion que comprenden un cabezal de depilacion equipado con un rodillo de depilacion movil en rotacion alrededor de un eje paralelo a la superficie de la piel a depilar. El rodillo de depilacion esta equipado en este caso de una serie de pinzas que se abren y se cierran a medida que el rodillo gira.In the aforementioned field, hair removal devices are already known which comprise a hair removal head equipped with a mobile hair removal roller in rotation about an axis parallel to the surface of the skin to be depilated. The hair removal roller is equipped in this case with a series of tweezers that open and close as the roller rotates.

10 Un aparato de este tipo esta descrito especialmente en un documento FR2686001 en nombre de la solicitante en el cual las pinzas de arranque estan formadas por una serie de laminas en rotacion que se apoyan contra unas laminas fijas que se encuentran enfrente, estando soportadas las laminas moviles de una fila por una carcasa periferica de un rodillo rotativo. Cada carcasa comprende unas excentricas que, durante el accionamiento en rotacion de la carcasa alrededor de un eje central, cooperan con unos caminos de excentricas formados por unas protuberancias 15 realizadas sobre un disco lateral en el extremo del rodillo. Tal aparato permite efectivamente arrancar los pelos corporales. Sin embargo, el hecho de que varias laminas moviles esten unidas ngidamente entre sf por una sola barquilla induce un reparto desigual del esfuerzo de pinzado y una eficacia reducida en caso de enganche de los pelos en una pinza o incluso una deformacion de una o varias laminas. Ademas, el esfuerzo mal controlado del pinzamiento del pelo puede tener como efecto la rotura del pelo en lugar del arranque hasta su rafz. En este caso, el 20 peso se repondra inmediatamente y sera visible muy rapidamente.10 An apparatus of this type is especially described in document FR2686001 on behalf of the applicant in which the starter clamps are formed by a series of rotating plates that are supported against fixed plates facing each other, the plates being supported mobile of a row by a peripheral housing of a rotating roller. Each housing comprises eccentrics that, during the rotation of the housing around a central axis, cooperate with eccentric paths formed by protrusions 15 made on a lateral disk at the end of the roller. Such device allows to effectively tear out body hairs. However, the fact that several mobile sheets are connected tightly to each other by a single wafer induces an uneven distribution of the clamping effort and a reduced efficiency in case of hooking the hairs into a clamp or even a deformation of one or several sheets . In addition, the poorly controlled effort of hair clamping can have the effect of hair breakage rather than tearing up the root. In this case, the 20 weight will be replenished immediately and will be visible very quickly.

Se conoce otro documento JP2001037533 que divulga un aparato de depilar que comprende una serie de pinzas, repartidas en varias filas alrededor de un cilindro que gira, a razon de dos pinzas por fila, estando compuesta cada fila por una lamina fija y una lamina movil. Las dos laminas moviles vecinas son accionadas simultaneamente por un elemento elastico que empuja los extremos inferiores de las laminas moviles hacia el exterior por lo que las pinzas 25 permanecen normalmente abiertas. Unos accionadores empujan, deslizandose por los caminos de excentricas laterales, los extremos inferiores de las laminas moviles para el cierre de las pinzas. Sin embargo, la utilizacion de un resorte aqrn no sirve para cerrar las pinzas. Este documento no propone una depiladora con cierre rapido de las pinzas.Another document JP2001037533 is known which discloses a depilatory apparatus comprising a series of tweezers, distributed in several rows around a rotating cylinder, at the rate of two tweezers per row, each row being composed of a fixed sheet and a mobile sheet. The two neighboring mobile plates are actuated simultaneously by an elastic element that pushes the lower ends of the mobile plates outwards so that the clamps 25 remain normally open. Actuators push, sliding down the paths of lateral eccentrics, the lower ends of the mobile plates for closing the clamps. However, the use of a spring here does not serve to close the clamps. This document does not propose a epilator with rapid closing of the tweezers.

Surge por lo tanto la necesidad de un aparato de depilar eficaz cuyo esfuerzo de pinzamiento sobre cada pinza sea 30 homogeneo y equilibrado.The need therefore arises for an effective hair removal device whose clamping effort on each clamp is homogeneous and balanced.

Otro objetivo del invento es un aparato de depilar que tenga un numero de pinzas de arranque mas elevado.Another object of the invention is a hair removal device having a higher number of starter pliers.

Otro objetivo del invento es un aparato de depilar que tenga una mayor rapidez en el cierre de las pinzas.Another objective of the invention is a hair removal device that has a faster closing of the tweezers.

Otro objetivo del invento es un aparato de depilar mas robusto con menor deterioro.Another object of the invention is a more robust hair removal apparatus with less deterioration.

Un objetivo del invento es incluso un aparato de depilar mas compacto.An object of the invention is even a more compact hair removal device.

35 Con el fin de alcanzar estos objetivos, el invento se refiere a un rodillo con un cabezal de depilacion para un aparato de depilar que comprende una caja que encierra un motor que incluye a su vez: un eje central fijo de eje A destinado a estar unido en rotacion a la caja; una jaula tubular que esta destinada a ser accionada en rotacion alrededor del eje central por el motor (4) y que soporta unas pinzas de arranque formada cada una por una lamina fija unida de manera ngida a la jaula tubular y por una lamina movil entre una posicion abierta en la cual la lamina movil esta 40 alejada de la lamina fija y una posicion cerrada en la cual la lamina movil esta en contacto con la lamina fija; unos medios de maniobra de las laminas moviles entre su posicion de abertura y de cierre durante la rotacion de la jaula tubular alrededor del eje central. Segun el invento, los medios de maniobra comprenden:In order to achieve these objectives, the invention relates to a roller with a depilation head for a hair removal device comprising a box that encloses a motor which in turn includes: a fixed central axis of axis A intended to be attached in rotation to the box; a tubular cage that is intended to be rotatably driven around the central axis by the motor (4) and that supports starter clamps each formed by a fixed sheet connected neatly to the tubular cage and by a mobile sheet between a open position in which the mobile sheet is away from the fixed sheet and a closed position in which the mobile sheet is in contact with the fixed sheet; means for maneuvering the mobile plates between their opening and closing position during the rotation of the tubular cage around the central axis. According to the invention, the maneuvering means comprise:

- asociado a cada lamina movil, al menos un muelle de recuperacion destinado a llevar a la citada lamina movil a la posicion de cerrada;- associated with each mobile sheet, at least one recovery spring intended to bring said mobile sheet to the closed position;

45 - asociado a cada lamina movil, un medio de apertura individual solidario con la citada lamina movil para accionarla45 - associated to each mobile lamina, a means of individual opening in solidarity with said mobile lamina to activate it

en rotacion, estando destinado el citado medio de apertura a desplazarse, para la apertura de la lamina movil, bajo la accion de unos medios de accionamiento de las pinzas.in rotation, said opening means being intended to be moved, for the opening of the mobile foil, under the action of means for actuating the clamps.

Los esfuerzos son generados independientemente sobre cada pinza, lo que garantiza un buen mantenimiento del pelo cualquiera que sea la situacion sobre las demas pinzas. Es decir, que los esfuerzos permiten coger el pelo 50 suficientemente sin romperlo y sin dejarle deslizarse durante el movimiento de arranque. Por otra parte, como el muelle asegura el contacto entre las dos pinzas al accionar el pivote, el contacto es siempre efectivo cualesquiera que sean las tolerancias en las diferentes piezas.The efforts are generated independently on each clip, which guarantees a good maintenance of the hair whatever the situation on the other clips. That is, the efforts allow to catch the hair 50 sufficiently without breaking it and without letting it slide during the starter movement. On the other hand, as the spring ensures the contact between the two clamps when the pivot is operated, the contact is always effective whatever the tolerances in the different parts.

Segun una variante preferida del invento, un muelle de recuperacion unico esta asociado a cada lamina movil. Esto permite facilitar la fabricacion del rodillo de depilacion y disminuir su coste.According to a preferred variant of the invention, a single recovery spring is associated with each mobile sheet. This makes it easier to manufacture the hair removal roller and reduce its cost.

De acuerdo con el invento, cada lamina movil es rotativa alrededor de un eje de pivotado A' normal al eje central y dispuesto en la jaula tubular. Esto permite un montaje de las pinzas simplificado puesto que las laminas moviles pueden estar enganchadas en la jaula al nivel del eje de pivotado. Ademas, esta construccion permite poner mas pinzas en el rodillo dce depilacion lo que hace la depilacion mas eficaz.According to the invention, each mobile sheet is rotatable about a pivot axis A 'normal to the central axis and arranged in the tubular cage. This allows a simplified assembly of the clamps since the mobile sheets can be hooked in the cage at the level of the pivot axis. In addition, this construction allows more tweezers to be placed on the roll of the hair removal, which makes hair removal more effective.

Ademas, el medio de apertura forma con la lamina movil un angulo a no nulo e incluye un abultamiento destinado a entrar en contacto con los medios de accionamiento para bascular la lamina movil hasta su posicion abierta alrededor del eje de pivotado A'. El abultamiento presenta la forma de una protuberancia redondeada que necesita una concepcion muy sencilla. Es sin embargo bastante robusta como consecuencia de la pequena presencia de rozamiento.In addition, the opening means forms a non-zero angle with the mobile sheet and includes a bulge intended to come into contact with the actuating means for tilting the mobile sheet to its open position around the pivoted axis A '. The bulge has the shape of a rounded protuberance that needs a very simple conception. It is however quite robust as a result of the small presence of friction.

En un modo de realizacion segun el invento, el angulo a esta cerca de los 90° para minimizar el tamano del rodillo de depilacion y garantizar un mejor accionamiento de las pinzas.In an embodiment according to the invention, the angle is close to 90 ° to minimize the size of the hair removal roller and ensure a better actuation of the tweezers.

Segun una variante de este invento, la citada lamina movil tiene una forma simetrica con respecto a un plano de simetna que incluye el citado eje Ay el abultamiento es asimetrico con respecto al citado plano de simetna. Esta forma asimetrica del abultamiento permite minimizar los esfuerzos al contacto con el medio de apertura y una perrdida del contacto rapida al quitarlo.According to a variant of this invention, said mobile sheet has a symmetrical shape with respect to a plane of symmetry which includes said axis A and the bulge is asymmetric with respect to said plane of symmetry. This asymmetric form of the bulge allows to minimize the efforts on contact with the opening means and a loss of rapid contact upon removal.

Segun un modo de realizacion del invento, cada muelle de recuperacion se interpone entre una lamina movil y la jaula tubular. La lamina movil esta sometida a la accion de recuperacion directamente, al apoyarse el muelle sobre una cara lateral de la lamina movil y una pared lateral de la jaula tubular que esta enfrente de la lamina fija.According to one embodiment of the invention, each recovery spring is interposed between a mobile sheet and the tubular cage. The mobile sheet is subjected to the recovery action directly, when the spring is supported on a side face of the mobile sheet and a side wall of the tubular cage that is in front of the fixed sheet.

Segun otro modo de realizacion del invento, cada muelle de recuperacion se interpone entre un medio de apertura y la jaula tubular. En este caso, la lamina movil es accionada en rotacion por el medio de apertura que esta sometido a su vez a la accion de recuperacion.According to another embodiment of the invention, each recovery spring is interposed between an opening means and the tubular cage. In this case, the mobile sheet is rotated by the opening means which is in turn subjected to the recovery action.

Ventajosamente, los citados medios de accionamiento de las pinzas estan dispuestos sustancialmente en la citada superficie cilmdrica exterior del eje central. Esto tiene como objetivo crear una zona de apertura de las pinzas en el penmetro del eje central con unos elementos elevados con respecto al eje central destinados a hacer basculare la lamina movil.Advantageously, said means for actuating the clamps are arranged substantially on said cylindrical outer surface of the central axis. This aims to create an area for opening the clamps on the central axis penimeter with elevated elements relative to the central axis designed to swing the mobile sheet.

Preferentemente, los medios de accionamiento de las pinzas incluyen al menos un rodillo excentrico con un eje de simetna A'' siendo el citado eje de simetna A'' paralelo al citado eje A.Preferably, the means for actuating the clamps include at least one eccentric roller with an axis of symmetry A '' said axis of symmetry A '' being parallel to said axis A.

Segun un modo de realizacion preferente, los medios de accionamiento de la pinza incluyen un numero de rodillos excentricos comprendidos entre 2 y 4, preferiblemente 3, que estan repartidos sobre una zona del eje central que ocupa cerca de un tercio de la circunferencia del eje central. El numero y el tamano de los rodillos depende del tamano global del sistema, del de la lamina movil, del abultamiento del tamano de la apertura deseada para la pinza, asf como de la rapidez de apertura y de cierre deseada. Cuanto mayor es el diametro del rodillo con respecto al del cabezal, mas progresivas seran la apertura y el cierre de la pinza pues el abultamiento va a subir/bajar segun la pendiente inducida por este diametro. Las pinzas deben cerrarse rapidamente para una buena eficaz del arranque, y por lo tanto es deseable tener una pendiente empinada y por lo tanto un rodillo lo mas pequeno posible, pero que induzca unos esfuerzos reducidos al contacto del abultamiento sobre el rodillo para minimizar el deterioro y el ruido.According to a preferred embodiment, the clamp drive means includes a number of eccentric rollers between 2 and 4, preferably 3, which are distributed over an area of the central axis that occupies about one third of the circumference of the central axis. . The number and size of the rollers depends on the overall size of the system, that of the mobile sheet, the bulge of the size of the desired opening for the clamp, as well as the speed of opening and closing desired. The larger the diameter of the roller with respect to that of the head, the more progressive the opening and closing of the clamp will be because the bulge will rise / fall according to the slope induced by this diameter. The clamps must be closed quickly for a good starting efficiency, and therefore it is desirable to have a steep slope and therefore a roller as small as possible, but that induces reduced efforts to the contact of the bulge on the roller to minimize deterioration. And the noise

Ademas, el/los rodillos excentricos estan libres en rotacion alrededor de su/sus ejes de simetna A'' con el fin de introducir un rodamiento sin deslizamiento sobre el eje central y limitar asf los rozamientos.In addition, the eccentric rollers are free to rotate around their / their symmetry axes A '' in order to introduce a bearing without sliding on the central axis and thus limit friction.

Ventajosamente, se puede contemplar igualmente un aparato para depilar que incluya una carcasa prevista para ser cogida con la mano que contenga un motor electrico de accionamiento y que comprenda un rodillo con un cabezal de depilacion segun el invento.Advantageously, it is also possible to contemplate an apparatus for depilating that includes a housing intended to be picked up by hand containing an electric drive motor and comprising a roller with a depilation head according to the invention.

Segun un modo de realizacion de un aparato para depilar, el rodillo del cabezal de depilacion es desmontable e intercambiable con otro accesorio de cuidado corporal. Se entiende aqrn por accesorio de cuidado corporal a cualquier medio de tratamiento de una parte del cuerpo humano tal como un accesorio de masaje, un accesorio de exfoliacion o incluso un cabezal de afeitado/de corte de pelo, etc.According to an embodiment of an apparatus for depilating, the hair removal roller is removable and interchangeable with another body care accessory. Aqrn is understood as a body care accessory to any means of treating a part of the human body such as a massage accessory, an exfoliation accessory or even a shaving / hair cutting head, etc.

Un aparato de depilar (A) electrico y mecanico segun el invento, tal como el ilustrado en las figuras 1 y 2, comprende una carcasa hueca, designada en su conjunto con la referencia 1, que esta constituida por dos semi-cascos 2 y 3 monoblocs que definen juntos, por una parte, por sus superficies exteriores, una zona de aprehension de la depiladora y, por otra parte, una carcasa de confinamiento y de mantenimiento de los diferentes elementos funcionales constitutivos de la depiladora. Asf, la carcasa 1 contiene un motor electrico 4 asociado a unos medios de transmision 5 del movimiento de rotacion del pinon de salida 6 del motor electrico 4. Segun el ejemplo ilustrado, los medios de transmision 5 incluyen un tren de engranajes de ejes paralelos al eje de rotacion del motor.An electrical and mechanical hair removal apparatus (A) according to the invention, such as that illustrated in Figures 1 and 2, comprises a hollow housing, designated as a whole with reference 1, which is constituted by two half-hulls 2 and 3 monoblocks that define together, on the one hand, by their outer surfaces, an area of apprehension of the epilator and, on the other hand, a housing of confinement and maintenance of the different functional elements constituting the epilator. Thus, the housing 1 contains an electric motor 4 associated with transmission means 5 of the rotation movement of the output pin 6 of the electric motor 4. According to the illustrated example, the transmission means 5 includes a gear train with axes parallel to the motor rotation axis.

La carcasa esta equipada con un cabezal de depilacion 10 que comprende un cuerpo hueco 11 que delimita una camara de depilacion 12 en del interior de la cual esta dispuesto un rodillo de depilacion 13 que aflora al nivel de la ventana 14 situada en el cuerpo hueco 11. El rodillo de depilacion 13 es en parte movil en rotacion alrededor de un eje A y se encuentra accionado en rotacion a traves de los medios de transmision 5 por el motor electrico 4. El rodillo de depilacion 13 incluye al nivel de su periferia una serie de pinzas 15 que se abren y se cierran en funcion de la rotacion del rodillo. Segun un modo de realizacion del invento, el rodillo de depilacion 13 comprende unos medios de fijacion reversibles (no ilustrados) en la carcasa 1 que permiten hacer desmontable el rodillo. Esto esta en el estado de la tecnica y al alcance del experto.The housing is equipped with a hair removal head 10 comprising a hollow body 11 that delimits a hair removal chamber 12 inside which is disposed a hair removal roller 13 that emerges at the level of the window 14 located in the hollow body 11 The hair removal roller 13 is partly mobile in rotation around an axis A and is rotated by means of the transmission means 5 by the electric motor 4. The hair removal roller 13 includes at the level of its periphery a series of pliers 15 that open and close depending on the rotation of the roller. According to one embodiment of the invention, the depilation roller 13 comprises reversible fixing means (not shown) in the housing 1 which allows the roller to be detachable. This is in the state of the art and within the reach of the expert.

El invento se refiere de una manera mas particular a la concepcion del rodillo 13 de depilacion designado igualmente con la terminologfa rodillo del cabezal de depilacion.The invention relates in a more particular way to the conception of the depilation roller 13 also designated with the terminology of the depilation head roller.

El rodillo 13 comprende, como lo muestra de una manera mas particular la figura 3, un eje central 20 fijo destinado a estar unido a la carcasa ya sea de una manera directa, ya sea por medio de una pieza movil que permita la regulacion de la posicion angular del eje central 20 con respecto a la carcasa. El rodillo 13 incluye igualmente una jaula tubular 21 que lleva las pinzas 15 y que es movil en rotacion alrededor del eje central 20 al ser accionada por medio de una rueda 22 unida en rotacion a la jaula tubular 21. Segun el ejemplo ilustrado, la jaula tubular 21 comprende seis pasadores 23, visibles en la figura 3, y que estan montados solidarios con la jaula tubular 21 y que llevan cada uno una fila de seis pinzas 15 de arranque alineadas segun una direccion D sensiblemente paralela al eje A.The roller 13 comprises, as shown in a more particular way in figure 3, a fixed central axis 20 intended to be attached to the housing either directly, or by means of a mobile part that allows the regulation of the angular position of the central axis 20 with respect to the housing. The roller 13 also includes a tubular cage 21 which carries the clamps 15 and which is mobile in rotation around the central axis 20 when driven by means of a wheel 22 rotatably connected to the tubular cage 21. According to the illustrated example, the cage Tubular 21 comprises six pins 23, visible in Figure 3, and which are mounted in solidarity with the tubular cage 21 and each bearing a row of six starting pliers 15 aligned according to a direction D substantially parallel to the A axis.

Cada pinza de arranque 15 esta formada por una lamina fija 25 y una lamina movil 26. Las laminas fijas 25 estan unidas de manera ngida a la jaula tubular 21 en la medida en la que, segun el ejemplo ilustrado, las laminas fijas 25 de una misma fila forman parte integrante del pasador 23 correspondiente. Cada lamina movil 26 comprende, por una parte, un cabezal de la lamina 261 que es una parte operativa destinada a apoyarse contra la lamina fija 25 para formar una zona de pinzado y, por otra parte, un pie de la lamina 262 unido de manera ngida a un cilindro o al eje de pivotado 8. Este ultimo esta libre en rotacion alrededor de un eje de pivotado A' y esta unido en traslacion al pasador 23 por un enganche, siendo el eje de pivotado A' normal al eje A. Cada lamina movil 26 es susceptible de desplazarse por rotacion entre una posicion abierta O visible en la figura 9 y una posicion cerrada F visible en la figura 10.Each starter clamp 15 is formed by a fixed sheet 25 and a mobile sheet 26. The fixed sheets 25 are connected to the tubular cage 21 closely to the extent that, according to the illustrated example, the fixed sheets 25 of a same row form an integral part of the corresponding pin 23. Each mobile sheet 26 comprises, on the one hand, a head of the sheet 261 which is an operative part intended to rest against the fixed sheet 25 to form a pinching zone and, on the other hand, a foot of the sheet 262 joined in a manner attached to a cylinder or pivot axis 8. The latter is free to rotate around a pivot axis A 'and is connected in translation to pin 23 by a hitch, the pivot axis A' being normal to axis A. Each mobile sheet 26 is capable of rotating by rotation between an open position O visible in figure 9 and a closed position F visible in figure 10.

Con el fin de asegurar los movimientos de las laminas moviles 26, el rodillo 13 comprende unos medios de maniobra que integran a varios elementos que interactuan. Tal como es visible en la figura 7, por cada pinza 15, un medio de apertura 9 bajo la forma de un basculador esta unido en rotacion a la lamina movil 26 con un angulo a por el bies del cilindro de pivotado 8. Este angulo a puede elegirse entre un intervalo de (70°, 110°), siendo un angulo de 90° el que esta mejor adaptado a la realizacion del aparato. La lamina movil 26, el cilindro de pivotado 8 y el basculador 9, designados igualmente con la terminologfa medio de apertura, forman preferiblemente una pieza solida unica.In order to ensure the movements of the mobile plates 26, the roller 13 comprises maneuvering means that integrate several interacting elements. As is visible in Figure 7, for each clamp 15, an opening means 9 in the form of a jogger is rotatably connected to the mobile sheet 26 with an angle a by the bias of the pivot cylinder 8. This angle a It can be chosen from a range of (70 °, 110 °), with an angle of 90 ° which is best adapted to the realization of the apparatus. The mobile sheet 26, the pivot cylinder 8 and the jogger 9, also designated with the middle opening terminology, preferably form a single solid piece.

En funcionamiento, como esta ilustrado en la figura 9, al estar la lamina movil 26 pivotando sobre la jaula tubular 21 gira alrededor del eje central 20 sobre el cual, estan situados 3 rodillos 31 excentricos al nivel de una zona de apertura (Z, O) de las pinzas 15 correspondiente sustancialmente a alrededor de un tercio de la circunferencia delIn operation, as illustrated in Figure 9, as the mobile sheet 26 pivoting on the tubular cage 21 rotates around the central axis 20 on which 3 eccentric rollers 31 are located at the level of an opening area (Z, O ) of the pliers 15 corresponding substantially to about one third of the circumference of the

eje central 20. Cuando la pinza 15 pasa por encima de estos rodillos 31, un abultamiento 91 que forma parte del basculador 9 se pone en contacto con los rodillos 31 sucesivamente lo que hace bascular la lamina movil 26 en una direccion anti-horaria tal y como esta esquematizado en la figura 4 y la mantiene en la posicion abierta O durante un cierto tiempo. Aqm, el abultamiento 91 esta presentado bajo la forma de una protuberancia redondeada con respecto al basculador 9, sin embargo, puede tener tambien una forma diferente en tanto que asegura un contacto fluido con los rodillos 31 asf como un movimiento en rotacion de la lamina movil 26.central axis 20. When the clamp 15 passes over these rollers 31, a bulge 91 that is part of the jogger 9 is brought into contact with the rollers 31 successively which makes the mobile lamina 26 swing in an anti-hour direction such and as outlined in figure 4 and keeps it in the open position O for a certain time. Here, the bulge 91 is presented in the form of a rounded protuberance with respect to the jogger 9, however, it can also have a different shape in that it ensures a fluid contact with the rollers 31 as well as a rotating movement of the mobile sheet 26.

Cuando la pinza 15 abandona la zona de apertura Z.O y el abultamiento 91 no esta ya en contacto con ninguno de los rodillos 31, la lamina movil 26 sometida a la accion de recuperacion con el esfuerzo necesario para arrancar el pelo, pasa a la posicion de cerrada F y es mantenida allf gracias a al menos un muelle 7 situado en el rodillo 13 hasta que la pinza 15 pasa de nuevo a la zona de apertura ZO en donde el muelle 7 se comprime un poco mas, lo que permite un cierre rapido de la pinza 15,When the clip 15 leaves the opening zone ZO and the bulge 91 is no longer in contact with any of the rollers 31, the mobile sheet 26 subjected to the recovery action with the effort necessary to tear the hair, goes into the position of closed F and is maintained there thanks to at least one spring 7 located on the roller 13 until the clamp 15 passes back to the opening zone ZO where the spring 7 is compressed a little more, which allows a quick closing of the clamp 15,

Segun una primera variante, tal como es visible en la figura 4, el muelle 7 esta situado entre el basculador 9 y la jaula tubular 21. Mas exactamente, un extremo del muelle 7 esta posado sobre el basculador 9 por el lado que no tiene pasador y el otro extremo esta unido al pasador 23 que esta montado solidario con la jaula tubular 21, estando el muelle 7 en oposicion directa con el esfuerzo de empuje de los rodillos 31.According to a first variant, as visible in Figure 4, the spring 7 is located between the jogger 9 and the tubular cage 21. More precisely, one end of the spring 7 is perched on the jogger 9 on the side that has no pin and the other end is connected to the pin 23 which is mounted integral with the tubular cage 21, the spring 7 being in direct opposition to the thrust of the rollers 31.

Segun una segunda variante, tal como es visible en la figura 5, el muelle 7 esta situado entre la lamina movil 26 y la jaula tubular 21. De hecho, un extremo esta en contacto directo con una superficie lateral de la lamina movil 26 para empujarla contra la lamina fija 25, y el otro extremo esta fijo sobre una pared lateral del pasador 23 que esta enfrente de la lamina fija 25.According to a second variant, as is visible in Figure 5, the spring 7 is located between the mobile sheet 26 and the tubular cage 21. In fact, one end is in direct contact with a lateral surface of the mobile sheet 26 to push it against the fixed sheet 25, and the other end is fixed on a side wall of the pin 23 facing the fixed sheet 25.

Los muelles de compresion pueden ser reemplazados por unos alfileres o por unos muelles de torsion colocados sobre los pivotes al nivel de unos ejes de rotacion de las laminas moviles 26. Se pueden utilizar tambien unos muelles de laminas colocados indiferentemente en el mismo lugar que los muelles de pestana u otros. Los muelles de compresion pueden ser reemplazados por unos muelles de traccion con un funcionamiento inverso en los que durante el basculado los muelles estan estirados.The compression springs can be replaced by pins or by torsion springs placed on the pivots at the level of rotational axes of the mobile plates 26. Laminated springs can also be used indifferently placed in the same place as the springs of pestana or others. The compression springs can be replaced by traction springs with an inverse operation where the springs are stretched during tipping.

Debido a esto, se puede imaginar otro posicionamiento que permita mantener la pinza cerrada y que se abra por un basculado que comprima el muelle 7. Por ejemplo, una forma simetrica con el abultamiento a un lado y el muelle al otro, como esta ilustrado en la figura 6. El muelle 7 esta por lo tanto estirado permanentemente.Because of this, another positioning can be imagined that allows the clamp to be kept closed and that is opened by a tilt that compresses the spring 7. For example, a symmetrical shape with the bulge on one side and the spring on the other, as illustrated in Figure 6. The spring 7 is therefore permanently stretched.

Los rodillos excentricos 31 estan preferiblemente con rodadura libre en el eje central 20 para permitir un contacto de rodadura sin deslizamiento entre el abultamiento 91 y el rodillo 31 y por lo tanto minimizar asf los danos y el deterioro.The eccentric rollers 31 are preferably with free rolling on the central shaft 20 to allow a rolling contact without sliding between the bulge 91 and the roller 31 and therefore minimize damage and deterioration.

Segun una alternativa contemplada, tal como es visible en las figuras 10 y 11, los medios de accionamiento 30 de las pinzas comprenden un unico rodillo excentrico, o incluso con el mismo objetivo, el eje central 20 puede presentar una forma asimetrica para tener una zona de apertura en protuberancia. En consecuencia, la duracion durante la cual la lamina movil 26 permanece abierta, corresponded a la duracion durante la cual un punto del abultamiento 91 permanece en contacto con la parte alta del rodillo 31 que es relativamente corta. Para tener una duracion o un intervalo de apertura suficiente sin tener que perder rapidez en el cierre, se prefiere la utilizacion de varios rodillos para el accionamiento de las pinzas como se ha explicado anteriormente. Como referencia, el motor acciona en rotacion el cilindro a una velocidad igual a unas 1500 rev/min.According to an alternative contemplated, as is visible in Figures 10 and 11, the actuator means 30 of the clamps comprise a single eccentric roller, or even with the same objective, the central axis 20 can have an asymmetrical shape to have a zone Opening in extrusion. Consequently, the duration during which the mobile sheet 26 remains open corresponds to the duration during which a bulge point 91 remains in contact with the high part of the roller 31 which is relatively short. In order to have a duration or a sufficient opening interval without having to lose speed in closing, the use of several rollers is preferred for the operation of the clamps as explained above. As a reference, the engine rotates the cylinder at a speed equal to about 1500 rev / min.

Con el fin de aumentar todavfa mas la rapidez de cierre, se puede contemplar igualmente otra construccion del basculador como esta ilustrado en la figura 12: de manera general, cada lamina movil 26 es una pieza simetrica con respecto a un plano de simetna PS, tal como es visible en la figura 7. Al ser rotativa la lamina movil 26 con la jaula tubular 21 alrededor del eje A, este ultimo coincide con el plano de simetna PS. En la figura 12, el abultamiento presenta una forma asimetrica con respecto al plano PS y una disminucion del espesor desde la derecha hacia la izquierda de manera sucesiva, lo que permite minimizar los esfuerzos a la entrada de la zona de apertura y una perdida de contacto rapida a la salida.In order to increase the closing speed even more, another construction of the jogger can also be contemplated as illustrated in Figure 12: in general, each mobile sheet 26 is a symmetrical piece with respect to a plane of symmetry PS, such as is visible in Figure 7. Since the mobile lamina 26 is rotatable with the tubular cage 21 around the axis A, the latter coincides with the plane of symmetry PS. In figure 12, the bulge has an asymmetric shape with respect to the PS plane and a decrease in thickness from the right to the left in a successive manner, which minimizes the efforts at the entrance of the opening area and a loss of contact Quick on departure.

En los modos de realizacion presentados, se utilizan laminas moviles 26 metalicas en contacto directo con los pasadores 23 plasticos a modo de laminas fijas 25, con un contacto de pinzado metal-plastico. Se pueden insertar igualmente unas laminas fijas 25 metalicas en los pasadores 23 por moldeado o por enganche o incluso simplemente por colocacion, para tener un contacto metal-metal. Se pueden utilizar tambien laminas moviles enteramente de material plastico o incluso, sobre una u otra lamina, utilizar elementos ceramicos sobre toda o una parte de las piezas.In the embodiments presented, metal sheets 26 are used in direct contact with the plastic pins 23 as fixed plates 25, with a metal-plastic pinch contact. Fixed metal sheets 25 can also be inserted into the pins 23 by molding or by hooking or even simply by placement, to have a metal-metal contact. You can also use mobile sheets entirely of plastic material or even, on one or another sheet, use ceramic elements on all or part of the pieces.

Por supuesto que, pueden aportarse otras modificaciones al invento en el marco de las reivindicaciones anexas.Of course, other modifications can be made to the invention in the context of the appended claims.
