Description

La présente invention concerne le domaine technique des appareils à main d'épilation mécanique.The present invention relates to the technical field of hand-held mechanical hair removal apparatus.

De tels appareils de soins corporels comprennent généralement un corps creux équipé d'une tête d'épilation. L'appareil comprend également des moyens d'épilation mécanique qui sont disposés dans la tête d'épilation de manière à être situés au niveau d'une fenêtre de travail aménagée dans la tête. Ces moyens d'épilation mécanique sont le plus souvent formés par un tambour portant une pluralité de pinces d'épilation s'ouvrant et se fermant au fur et à mesure de la rotation du tambour en étant actionnées par des systèmes de cames. Le tambour est lui-même entraîné en rotation par un moteur électrique le plus souvent associé à un train d'engrenage. Un tel appareil d'épilation mécanique donne pleinement satisfaction en ce qui concerne sa fonction première d'épilation mais présente toutefois l'inconvénient d'être relativement bruyant en raison notamment du nombre de pièces mécaniques en mouvement et, plus particulièrement, du moteur électrique et du train d'engrenage associé.Such body care appliances generally comprise a hollow body equipped with an epilation head. The apparatus also comprises mechanical depilatory means which are arranged in the epilating head so as to be located at a working window arranged in the head. These mechanical depilatory means are most often formed by a drum carrying a plurality of epilation forceps opening and closing as the rotation of the drum being actuated by cam systems. The drum is itself rotated by an electric motor most often associated with a gear train. Such a mechanical epilation device gives full satisfaction with regard to its primary function hair removal but has the disadvantage of being relatively noisy due in particular to the number of moving mechanical parts and, more particularly, the electric motor and of the associated gear train.

W002076260 décrit un appareil de soin qui peut être un appareil d'épilation, comprenant un corps, une tête de traitement de la peau et des moyens de traitement de la peau. La tête de traitement de cet appareil comprend une peau recouvrant la tête uniquement et pouvant s'étendre jusqu'à la peau du patient pendant l'utilisation de l'appareil de traitement, en particulier par les collisions entre des disques d'épilation. Cette peau est principalement en matériau rigide transparent pour laisser visible et limiter le bruit généré par les disques de la tête d'épilation. W002076260 discloses a care apparatus which may be an epilation apparatus, comprising a body, a skin treatment head and skin treatment means. The treatment head of this apparatus comprises a skin covering the head only and may extend to the skin of the patient during use of the treatment apparatus, in particular by collisions between hair removal discs. This skin is mainly transparent rigid material to leave visible and limit the noise generated by the disks of the hair removal head.

Il est donc apparu le besoin d'un nouveau type d'appareil d'épilation mécanique qui soit moins bruyant à l'usage afin d'en améliorer les conditions d'utilisation.It has therefore emerged the need for a new type of mechanical hair removal device that is less noisy with use in order to improve the conditions of use.

Afin d'atteindre cet objectif, l'invention a pour objet un appareil à main d'épilation mécanique comprenant :

  • un corps creux,
  • une tête d'épilation qui équipe le corps et qui comprend des moyens d'épilation mécanique,
  • des moyens d'entraînement des moyens d'épilation mécanique, les moyens d'entraînement étant disposés à l'intérieur du corps creux,
In order to achieve this objective, the subject of the invention is a hand-held mechanical hair removal apparatus comprising:
  • a hollow body,
  • an epilation head which equips the body and which comprises means of mechanical depilation,
  • drive means of the mechanical depilatory means, the drive means being disposed inside the hollow body,

Selon l'invention, le corps creux est en partie au moins recouvert d'au moins une peau atténuatrice en matériau polymère.According to the invention, the hollow body is at least partially covered with at least one attenuating skin of polymer material.

La mise en oeuvre d'une telle peau atténuatrice permet de réduire la propagation à l'extérieur du corps des bruits mécaniques issus des moyens d'entraînement des moyens d'épilation mécanique. Ces bruits mécaniques sont composés notamment de bruits solidiens qui font intervenir par exemple des vibrations.The implementation of such an attenuating skin makes it possible to reduce the propagation outside the body of the mechanical noises coming from the drive means of the mechanical depilatory means. These mechanical noises are composed in particular of solid sounds that involve for example vibrations.

Selon l'invention, le corps creux peut présenter un caractère monobloc ou au contraire être formé par l'assemblage d'au moins deux demi-corps qui sont chacun recouvert en partie au moins d'une peau atténuatrice. La formation du corps creux à partir de demi-corps permet de faciliter le montage de l'appareil d'épilation.According to the invention, the hollow body may have a one-piece character or on the contrary be formed by the assembly of at least two half-bodies which are each partially covered at least with an attenuating skin. The formation of the hollow body from half-body makes it easier to assemble the hair removal apparatus.

Selon l'invention, chaque peau atténuatrice peut être disposée à l'intérieur du corps creux ou au contraire à l'extérieur de ce dernier. Cette dernière configuration permet, selon la nature du matériau polymère utilisé, de conférer à l'appareil d'épilation un toucher plus ou moins doux ou satiné ainsi qu'une certaine souplesse qui augmente l'agrément d'utilisation de l'appareil et le confort de sa prise en main.According to the invention, each attenuating skin may be disposed inside the hollow body or, on the contrary, outside the latter. This last configuration makes it possible, depending on the nature of the polymer material used, to give the hair removal apparatus a more or less soft or satin feel, as well as a certain flexibility which increases the user's pleasure of using the appliance and the comfort of his grip.

Selon l'invention, le corps creux peut être réalisé en tout matériau approprié tel que par exemple du métal comme de l'aluminium injecté. Le corps creux peut également être réalisé en matière plastique de toute nature appropriée. Ainsi, le matériau constitutif du corps peut être choisi parmi les matières plastiques thermoplastiques ou thermodures:

  • Selon une autre caractéristique de l'invention, le matériau constitutif de chaque peau peut être choisi parmi les élastomères :
    • thermoplastiques,
    • thermodur
ou des mélanges de ceux-ci.According to the invention, the hollow body may be made of any suitable material such as for example metal such as injected aluminum. The hollow body may also be made of plastic of any suitable nature. Thus, the material constituting the body may be chosen from thermoplastic plastics or thermodides:
  • According to another characteristic of the invention, the constituent material of each skin may be chosen from elastomers:
    • thermoplastics,
    • thermoset
or mixtures thereof.

Selon une autre caractéristique de l'invention, le matériau constitutif de chaque peau peut être choisi parmi les élastomères ou les polymères suivants :

  • les élastomères thermoplastiques,
  • les polyuréthanes thermoplastiques,
  • les élastomères thermodurs,
  • les polymères thermoplastiques.
According to another characteristic of the invention, the constituent material of each skin may be chosen from the following elastomers or polymers:
  • thermoplastic elastomers,
  • thermoplastic polyurethanes,
  • thermoset elastomers,
  • thermoplastic polymers.

Un matériau thermoplastique peut être préféré pour fournir un matériau recyclable car il peut se ramollir de façon répétée.A thermoplastic material may be preferred to provide a recyclable material as it may repeatedly soften.

Un élastomère est défini comme un matériau déformable de façon réversible.An elastomer is defined as a reversibly deformable material.

A cet égard, de bons résultats de réduction des bruits ont été obtenus en utilisant comme matériau constitutif du corps creux une matière plastique tandis que le matériau constitutif de chaque peau atténuatrice est un élastomère. Bien entendu, une telle combinaison n'est pas strictement nécessaire à la réalisation d'un appareil d'épilation conforme à l'invention et l'une ou l'autre des alternatives peut se présenter.In this respect, good noise reduction results have been obtained by using as a material of the hollow body a plastic material while the constituent material of each attenuating skin is an elastomer. Of course, such a combination is not strictly necessary for the production of an epilation apparatus according to the invention and one or the other of the alternatives may be present.

De même, de bonnes performances d'atténuation acoustique ont été obtenues lorsque chaque peau atténuatrice présente, à une distance supérieure à 15mm des bords du corps, une épaisseur supérieure ou égale à 3mm.Similarly, good acoustic attenuation performance has been obtained when each attenuating skin has, at a distance greater than 15mm from the edges of the body, a thickness greater than or equal to 3mm.

L'épaisseur de la peau peut être constante ou varier.The thickness of the skin can be constant or vary.

On considère des valeurs d'épaisseur sur la totalité du corps comprises entre 0,5 et 3,2 mm, par exemple de façon plus limitée entre 1,5 et 2 mm.Thickness values on the whole body are considered between 0.5 and 3.2 mm, for example more limited between 1.5 and 2 mm.

Les moyens d'épilation mettent en oeuvre un moteur électrique qui peut être alimenté au moyen d'un cordon électrique raccordé soit directement au réseau électrique, soit par l'intermédiaire d'un transformateur. Le moteur d'entraînement électrique peut également être alimenté par une ou plusieurs batteries situées à l'intérieur du corps. La commande du fonctionnement des moyens d'entraînement peut être effectuée de toute manière appropriée et, par exemple, mettre en oeuvre un interrupteur de commande porté par le corps.The depilation means use an electric motor that can be powered by means of an electrical cord connected either directly to the electrical network or via a transformer. The electric drive motor can also be powered by one or more batteries located inside the body. The control of the operation of the drive means can be carried out in any appropriate manner and, for example, implement a control switch carried by the body.

Selon une caractéristique de l'invention, l'interrupteur de commande est situé à l'intérieur du corps qui comprend une fenêtre de manoeuvre offrant un accès à l'interrupteur. Cette fenêtre de manoeuvre est alors obturée par un voile souple qui permet l'actionnement de l'interrupteur de commande tout en faisant obstacle à la propagation des bruits et donc aux fuites acoustiques. Selon l'invention, ce voile souple peut être réalisé en tout matériau polymère approprié tel que par exemple en élastomère. Selon l'invention, le voile souple peut faire partie intégrante d'une peau atténuatrice recouvrant le corps creux et former avec cette dernière un ensemble monobloc. Le voile souple peut, au contraire, être rapporté sur le corps creux. Ainsi, selon une caractéristique de l'invention, le voile souple est formé par une partie centrale d'un bouchon adapté sur le corps au niveau de la fenêtre de manoeuvre tandis que selon une autre caractéristique de l'invention, le voile souple fait partie intégrante d'une peau atténuatrice.According to a characteristic of the invention, the control switch is located inside the body which comprises a maneuvering window providing access to the switch. This maneuvering window is then closed by a flexible web that allows the actuation of the control switch while making obstacle to the spread of noise and therefore to acoustic leakage. According to the invention, this flexible web can be made of any suitable polymeric material such as for example elastomer. According to the invention, the flexible web may be an integral part of an attenuating skin covering the hollow body and form with the latter a one-piece assembly. The flexible web may, on the contrary, be reported on the hollow body. Thus, according to a characteristic of the invention, the flexible web is formed by a central portion of a plug adapted to the body at the maneuvering window while according to another characteristic of the invention, the flexible web is part of integral of an attenuating skin.

Selon l'invention, chaque peau atténuatrice peut être mise en place de différentes manières. Ainsi, chaque peau atténuatrice peut être rapportée à l'intérieur ou à l'extérieur du corps creux après fabrication de ce dernier. Selon une forme de réalisation, chaque peau atténuatrice est surmoulée sur une partie du corps creux. Un tel mode de réalisation, qui fait intervenir une bi-injection, permet d'obtenir une parfaite cohésion ou adhérence de chaque peau atténuatrice sur le corps ou la partie de corps creux à laquelle elle est associée.According to the invention, each attenuating skin can be put in place in different ways. Thus, each attenuating skin can be reported inside or outside the hollow body after manufacture of the latter. According to one embodiment, each attenuating skin is overmolded on a portion of the hollow body. Such an embodiment, which involves a bi-injection, allows to obtain a perfect cohesion or adhesion of each attenuating skin on the body or the hollow body part with which it is associated.

Selon l'invention, afin d'augmenter encore la réduction des bruits et notamment, des bruits mécaniques générés par l'entraînement des moyens d'épilation mécanique, l'appareil d'épilation à main peut comprendre un berceau qui est disposé à l'intérieur du corps creux, qui porte les moyens d'entraînement des moyens d'épilation mécanique et qui est lié au corps creux par l'intermédiaire de blocs amortisseurs en élastomère. La mise en oeuvre d'un tel berceau et des blocs amortisseurs en élastomère ou silent block permet un découplage mécanique entre le corps creux et le moteur réduisant ainsi la propagation du bruit du moteur à l'extérieur de l'appareil.According to the invention, in order to further increase the reduction of noises, and in particular mechanical noises generated by driving the mechanical depilatory means, the hand-held hair removal device may comprise a cradle which is arranged at the interior of the hollow body, which carries the drive means of the mechanical epilation means and which is connected to the hollow body by means of elastomer damping blocks. The implementation of such a cradle and damping blocks of elastomer or silent block allows a mechanical decoupling between the hollow body and the engine thus reducing the propagation of engine noise outside the device.

Toujours dans le but de réduire encore la propagation des bruits du moteur et selon une variante de réalisation de l'invention, le berceau comprend une paroi d'isolation qui définit avec la tête d'épilation et le corps creux un caisson de réception des moyens d'épilation mécanique et l'appareil comprend alors un joint périphérique d'isolation phonique interposé entre la paroi d'isolation et le corps creux.Still with the aim of further reducing the propagation of engine noise and according to an alternative embodiment of the invention, the cradle comprises an insulating wall which defines with the depilatory head and the hollow body a receiving box means mechanical depilation and the apparatus then comprises a peripheral sound insulation seal interposed between the insulation wall and the hollow body.

Bien entendu, les diverses caractéristiques, variantes et formes de réalisation de l'invention peuvent être associées les unes avec les autres selon diverses combinaisons dans la mesure où elles ne sont pas incompatibles ou exclusives les unes des autres.Of course, the various features, variants and embodiments of the invention can be associated with each other according to various combinations to the extent that they are not incompatible or exclusive of each other.

Par ailleurs, diverses autres caractéristiques et avantages de l'invention ressortent de la description ci-dessous effectuée en référence aux dessins annexés qui illustrent une forme non limitative de réalisation d'un appareil à main d'épilation mécanique selon l'invention.Moreover, various other features and advantages of the invention emerge from the description below made with reference to the accompanying drawings which illustrate a non-limiting embodiment of a mechanical hair removal device according to the invention.

La figure 1 est une coupe longitudinale schématique d'un appareil d'épilation à main.The figure 1 is a schematic longitudinal section of a hand-held hair removal device.

La figure 2 est une coupe transversale selon la ligne II.II de la figure 1.The figure 2 is a cross-section along the line II.II of the figure 1 .

L'appareil à main d'épilation mécanique, selon l'invention tel qu'illustré aux figures 1 et 2 et désigné dans son ensemble par la référence 1, comprend un corps 2 constitué de deux demi corps 3, 4. Le corps creux 2 est équipé d'une tête d'épilation 5 qui, selon l'exemple illustré, est adaptée de manière amovible sur le corps 2 étant entendu que la tête d'épilation 5 pourrait aussi être adaptée de manière définitive et indémontable sur ledit corps 2. La tête d'épilation 5 comprend des moyens d'épilation destinés à venir au contact de la peau, non représentée, par une fenêtre 7 de travail aménagée dans la tête d'épilation 5 à l'opposé du corps 2. Selon l'exemple illustré, les moyens d'épilation 6 sont formés par un rouleau comprenant une série de pinces à épiler réparties à la périphérie et sur la longueur du rouleau. Les pinces à épiler tournent avec le rouleau et sont actionnées en ouverture et en fermeture au fur et à mesure de la rotation du rouleau par un système de cames tel que par exemple décrit par la demande FR 2 804 844 incorporée ici à titre de référence. Des moyens d'épilation pourraient également mettre en oeuvre un mécanisme d'épilation tel que décrit par la demande FR 2 810 215 incorporée ici à titre de référence. Les moyens d'épilation ne constituent pas une caractéristique essentielle de l'invention et pourraient mettre en oeuvre tout autre dispositif connu de l'homme du métier. Les moyens d'épilation sont attachés à la tête d'épilation 5 et sont en saillie hors de la tête d'épilation lorsqu'ils viennent épiler la peau non représentée.The mechanical hair removal device according to the invention as illustrated in Figures 1 and 2 and designated as a whole by the reference 1, comprises a body 2 consisting of two half-bodies 3, 4. The hollow body 2 is equipped with an epilation head 5 which, according to the example shown, is removably adapted on the body 2, it being understood that the depilating head 5 could also be permanently and releasably adapted to said body 2. The epilation head 5 comprises depilation means intended to come into contact with the skin, not shown by a working window 7 arranged in the epilation head 5 opposite the body 2. According to the illustrated example, the depilating means 6 are formed by a roller comprising a series of tweezers distributed at the periphery and over the length of the roll. The tweezers rotate with the roller and are operated in opening and closing as the rotation of the roller by a cam system as for example described by the application FR 2 804 844 incorporated herein by reference. Hair removal means could also implement a hair removal mechanism as described by the application FR 2 810 215 incorporated herein by reference. Hair removal means are not an essential feature of the invention and could implement any other device known to those skilled in the art. The depilatory means are attached to the epilation head 5 and protrude out of the epilation head when they come to depilate the skin not shown.

Afin d'assurer le fonctionnement des moyens d'épilation 6, l'appareil 1 comprend des moyens d'entraînement 10 qui comprennent un moteur électrique entraînant un train d'engrenages 12 engrainant une roue d'entrainement 13 solidaire des moyens d'épilation 6. Afin de limiter une propagation solide des bruits mécaniques liés à la rotation du moteur 1 et du train d'engrenages 12, l'appareil selon l'invention comprend un berceau 15 qui porte le moteur électrique 11 et le train d'engrenage 12. Le berceau 15 est alors lié au corps creux par plusieurs et, selon l'exemple illustré, trois blocs amortisseurs 16 qui assurent un découplage mécanique du berceau 15 par rapport au corps creux. Les blocs amortisseurs 16, également appelés silent block, peuvent être réalisés de toute manière appropriée telle que par exemple en matériau élastomère. Afin d'optimiser au maximum le découplage mécanique, des blocs amortisseurs 16 sont réalisés de manière à présenter une raideur inférieure à 1/19e et de préférence 1/20e de la raideur du matériau constitutif du corps creux.In order to ensure the operation of the depilation means 6, the apparatus 1 comprises drive means 10 which comprise an electric motor driving a gear train 12 engraining a drive wheel 13 In order to limit a solid propagation of the mechanical noise related to the rotation of the motor 1 and the gear train 12, the apparatus according to the invention comprises a cradle 15 which carries the electric motor 11 and the gear train 12. The cradle 15 is then connected to the hollow body by several and, according to the illustrated example, three damping blocks 16 which provide a mechanical decoupling of the cradle 15 relative to the hollow body. The damping blocks 16, also called silent block, can be made in any appropriate manner such as for example elastomeric material. In order to optimize the maximum mechanical decoupling, damping blocks 16 are made so as to have a stiffness of less than 1 / 19th and preferably 1 / 20th of the stiffness of the material constituting the hollow body.

Selon l'exemple illustré et afin d'assurer un confinement acoustique du moteur 11, le berceau 15 comprend, au niveau de son extrémité située vers la tête d'épilation 5, une paroi d'isolation 17 qui définit avec le corps creux 2 et la tête d'épilation 5 un caisson 18 de réception des moyens d'épilation 6. L'appareil 1 comprend alors un joint périphérique 19 d'isolation phonique interposé entre la paroi 17 et le corps creux 2. Selon l'exemple illustré, le joint périphérique 19 est, afin d'en faciliter le montage, solidaire du berceau 15 en étant par exemple réalisé par surmoulage sur ledit berceau 15. De la même manière, les blocs amortisseurs 16 peuvent également être surmoulés sur le berceau 15.
Afin de réduire plus encore les émissions acoustiques de l'appareil d'épilation mécanique 1 selon l'invention, ce dernier comprend au moins une et, selon l'exemple illustré, deux peaux atténuatrices 23 et 24 qui recouvrent chacune l'extérieur du demi-corps 3, 4 correspondant. Ce mode de réalisation en deux parties de la peau atténuatrice vise à faciliter le montage de l'appareil à main d'épilation mécanique selon l'invention. Bien entendu, il pourrait être envisagé de mettre en oeuvre une seule peau atténuatrice qui serait rapportée sur le corps 2 après assemblage de ce dernier. De la même manière, dans la mesure où le corps 2 serait formé en une seule partie, la peau atténuatrice pourrait alors être en une seule partie ou en deux parties selon le mode d'assemblage de l'appareil 1.
Selon l'exemple illustré, les peaux atténuatrices 23 et 24 sont surmoulées sur les demi-corps 3 et 4 et sont constituées d'une matière polymère adaptée. La matière constitutive des peaux atténuatrice pourra par exemple être un polyuréthane thermoplastique ou un élastomère thermoplastique ou thermodur adapté. L'usage d'une telle peau en polyuréthane thermoplastique a les avantages suivants : la peau est auto-adhérente sur la coque (par exemple en ABS) de l'épilateur quand on le surmoule ce qui donne un avantage à la fabrication; la peau est transparente, elle a un toucher non salissant (elle n'absorbe pas les salissures), elle a un toucher doux qui notamment améliore le confort du maintien de l'épilateur), un corps gras type crème hydratante n'est pas absorbé par un tel matériau (l'absorption de corps gras pouvant conduire à un ramollissement de la peau). Pour assurer une atténuation optimale, le matériau constitutif de chaque peau atténuatrice 23, 24 pourra par exemple être choisi pour présenter une raideur inférieure à 1/19e et de préférence à 1/20e de la raideur du matériau constitutif du corps creux et n'ayant pas de fonction d'amortissement ou atténuatrice. Selon l'exemple illustré, l'alimentation électrique du moteur 11 est assurée au moyen d'un cordon électrique non représenté. Toutefois, cette alimentation électrique pourrait également être assurée par des batteries disposées à l'intérieur du corps creux 2. Afin de permettre une mise en marche et un arrêt du moteur 11, l'appareil 1 comprend un interrupteur 30 adapté sur le berceau 15, le corps 2 et selon l'exemple le demi-corps 4 comprend alors une fenêtre 31 pour la manoeuvre de l'interrupteur 30. Afin de réduire les fuites acoustiques au niveau de la fenêtre 31, cette dernière est obturée par un voile double souple 32 en matériau polymère. Selon l'exemple illustré, le voile 32 forme la partie centrale d'un bouchon 33 adapté sur le demi-corps 4 au niveau de la fenêtre 31. Ainsi, il est possible à un utilisateur de manoeuvrer l'interrupteur 30 en appuyant sur le voile 32.According to the illustrated example and in order to ensure acoustic confinement of the motor 11, the cradle 15 comprises, at its end located towards the epilation head 5, an insulation wall 17 which defines with the hollow body 2 and the epilating head 5 a box 18 for receiving the epilation means 6. The apparatus 1 then comprises a peripheral seal 19 sound insulation interposed between the wall 17 and the hollow body 2. According to the illustrated example, the Peripheral seal 19 is, in order to facilitate assembly, secured to the cradle 15 being for example made by overmolding on said cradle 15. Similarly, the damping blocks 16 may also be overmolded on the cradle 15.
In order to further reduce the acoustic emissions of the mechanical depilation apparatus 1 according to the invention, the latter comprises at least one and, according to the illustrated example, two attenuator skins 23 and 24 which each cover the outside of the half -body 3, 4 corresponding. This embodiment in two parts of the attenuating skin is intended to facilitate the mounting of the mechanical hair removal device according to the invention. Of course, it could be envisaged to implement a single attenuating skin that would be reported on the body 2 after assembly of the latter. In the same way, insofar as the body 2 would be formed in a single part, the attenuating skin could then be in one part or in two parts depending on the assembly mode of the apparatus 1.
According to the illustrated example, the attenuating skins 23 and 24 are overmolded on the half-bodies 3 and 4 and consist of a suitable polymer material. The The constituent material of the attenuating skins may for example be a thermoplastic polyurethane or a suitable thermoplastic or thermoset elastomer. The use of such a thermoplastic polyurethane skin has the following advantages: the skin is self-adhering on the shell (for example in ABS) of the epilator when it is overmolded which gives an advantage to the manufacture; the skin is transparent, it has a non-messy touch (it does not absorb dirt), it has a soft touch which notably improves the comfort of the maintenance of the epilator), a moisturizing type of body fat is not absorbed by such a material (the absorption of fatty substances that can lead to a softening of the skin). To ensure optimum attenuation, the constituent material of each attenuating skin 23, 24 may for example be chosen to have a stiffness of less than 1/19 e and preferably 1/20 e of the stiffness of the material constituting the hollow body and n having no damping or attenuating function. According to the illustrated example, the power supply of the motor 11 is provided by means of a not shown electrical cord. However, this power supply could also be provided by batteries arranged inside the hollow body 2. In order to allow a start and a stop of the motor 11, the apparatus 1 comprises a switch 30 adapted to the cradle 15, the body 2 and according to the example the half-body 4 then comprises a window 31 for the operation of the switch 30. In order to reduce acoustic leakage at the window 31, the latter is closed by a flexible double veil 32 made of polymeric material. According to the illustrated example, the web 32 forms the central part of a plug 33 fitted on the half-body 4 at the level of the window 31. Thus, it is possible for a user to operate the switch 30 by pressing the sail 32.

Selon l'exemple illustré, le voile 32 est porté par le bouchon 33. Toutefois, le voile 32 pourrait faire partie intégrante de la peau atténuatrice 24.According to the illustrated example, the web 32 is carried by the plug 33. However, the web 32 could be an integral part of the attenuating skin 24.

De la même manière, selon l'exemple illustré, chaque peau atténuatrice 23, 24 est située à l'extérieur du demi-corps correspondant 3, 4. Toutefois, selon l'invention, chaque peau atténuatrice pourrait être située à l'intérieur du corps 2. Bien entendu, diverses autres modifications peuvent être apportées à l'invention dans le cadre des revendications annexées.In the same way, according to the illustrated example, each attenuating skin 23, 24 is located outside the corresponding half-body 3, 4. However, according to the invention, each attenuating skin could be located inside the 2. Of course, various other modifications may be made to the invention within the scope of the appended claims.
