Abstract

The electrical toothbrush has a drive part (1) with a fitted brush (2). A shaft (4) having a lateral peg (5) which projects into an axial recess (6) at the end of the brush handle (3) is arranged at the end of the drive part (1). The surrounding wall (7) of the recess in the brush handle (3) has a perforation (10) which is closed on all sides and in which a pair of springs arms (8) is arranged. The spring arms (8) clamp around the peg (5) of the shaft (4) and are used for the axial fixation thereof. The surrounding wall (7) of the recess comprises the shaft (4) in front of and behind its peg and is used for positioning of the fitted brush on the shaft. By separating the functions "positioning" and "fixation" from one another a rigid, secure connection between the fitted brush and the shaft is guaranteed. Involuntary detachment of the fitted brush during operation is avoided.

Description

La présente invention est relative à un appareil électrique à main, en particulier à une brosse à dents électrique, consistant en une pièce de commande sur laquelle est montée une pièce constituant un instrument, une tige munie d'un ergot latéral étant agencée à l'extrémité de la pièce de commande, laquelle tige entre dans un évidement axial ménagé à l'extrémité de la pièce qui constitue l'instrument. The present invention relates to an electric hand appliance, in particular an electric toothbrush, consisting of a control part on which is mounted a part constituting an instrument, a rod provided with a lateral lug being arranged at the end of the control part, which rod enters an axial recess formed at the end of the part which constitutes the instrument.

De tels systèmes de raccord enfichables destinés à des brosses à dents électriques sont connus, par exemple, par les Brevets Suisses 357 705, 391 652 et 599 783. Such plug-in connection systems intended for electric toothbrushes are known, for example, from Swiss Patents 357,705, 391,652 and 599,783.

Les appareils comportent une pièce de commande en forme de poignée, un bout d'arbre, qui avance hors du carter de la pièce de commande, étant pourvu d'un pivot radial.The devices include a handle-shaped control part, a shaft end which projects out of the control part housing and is provided with a radial pivot.

Le manche de la brosse à dents comporte, de son côté, un évidement qui débouche sur sa face arrière, qui s'étend axialement, et dans lequel le bout d'arbre est introduit.The handle of the toothbrush has, for its part, a recess which opens on its rear face, which extends axially, and into which the shaft end is introduced.

Pendant le fonctionnement, la brosse à dents démontable, dont le manche est en alignement rectiligne avec l'arbre de commande, exécute un mouvement oscillant autour de son axe longitudinal. Dans les raccords connus, la paroi de l'évidement ménagé dans le manche de la brosse à dents est pourvue d'une fente longitudinale ouverte d'un seul côté, laquelle fente possède deux échancrures des deux côtés. Lorsqu'on place le bout d'arbre dans l'évidement, le pivot radial pénètre dans la fente longitudinale et encliquette dans les deux échancrures de celle-ci.During operation, the removable toothbrush, the handle of which is in rectilinear alignment with the control shaft, performs an oscillating movement around its longitudinal axis. In known fittings, the wall of the recess in the handle of the toothbrush is provided with a longitudinal slot open on one side, which slot has two notches on both sides. When the end of the shaft is placed in the recess, the radial pivot enters the longitudinal slot and snaps into the two notches thereof.

Les raccords connus sont désavantageux, étant donné que lors des efforts de rotation et de flexion de la brosse à dents démontable, efforts qui apparaissent inévitablement lors d'un usage normal, des forces entrent en action qui élargissent latéralement la fente longitudinale susmentionnée. Ainsi, l'effort latéral de serrage qui s'exerce sur le pivot radial, est-il réduit de sorte que le pivot n'est plus tenu que faiblement. Un petit effort longitudinal suffit déjà pour démonter involontairement la brosse à dents. Known connections are disadvantageous, given that during the rotational and bending forces of the removable toothbrush, forces which inevitably appear during normal use, forces come into play which laterally widen the aforementioned longitudinal slot. Thus, the lateral clamping force exerted on the radial pivot, is it reduced so that the pivot is no longer held only weakly. A small longitudinal effort is already enough to unintentionally dismantle the toothbrush.

L'ajustement de la brosse à dents enfichable, sur le bout d'arbre dépend également de la tolérance de fabrication. Afin de mieux contrôler au moins ce facteur d'influence, le Brevet Suisse 599 783 propose de prévoir dans la zone de l'évidement ménagé à l'extrémité du manche de la brosse, une pluralité de rainures internes réparties sur la périphérie intérieure. On obtient ainsi la formation de zones axiales d'épaisseur de paroi radiale réduite et d'élasticité de ce fait augmentée, réparties sur le pourtour du manche de la brosse à dents, lequel est habituellement réalisé en matière plastique, ce qui améliore l'aptitude-à l'écartement élastique de la fente longitudinale lors de l'insertion de la brosse à dents. The adjustment of the plug-in toothbrush on the shaft end also depends on the manufacturing tolerance. In order to better control at least this influence factor, Swiss Patent 599,783 proposes to provide in the region of the recess formed at the end of the brush handle, a plurality of internal grooves distributed over the inner periphery. There is thus obtained the formation of axial zones of reduced radial wall thickness and thereby increased elasticity, distributed around the periphery of the handle of the toothbrush, which is usually made of plastic, which improves the ability -the elastic spacing of the longitudinal slot when inserting the toothbrush.

Cela aboutit à une flexibilité élastique dans la zone d'embouchure de l'évidement et est réputé donner une plus grande sécurité au raccord.This results in elastic flexibility in the mouth area of the recess and is said to give greater security to the fitting.

Dans la pratique, il s'est cependant avéré que même la configuration avec des rainures ne garantit pas, elle non plus, un ajustement impeccable de la brosse à dents enfichable, sur le bout d'arbre de la pièce de commande, de sorte que lors d'un grand effort, le manche de la brosse à dents peut, dans ce cas également, se détacher de la pièce de commande. In practice, however, it has turned out that even the configuration with grooves does not guarantee an impeccable fit of the plug-in toothbrush on the shaft end of the control part either, so that during a great effort, the handle of the toothbrush can, in this case also, detach from the control part.

L'invention a en conséquence pour but d'améliorer l'appareil à main électrique mentionné dans le préambule, de telle sorte que ni des efforts de flexion, ni des efforts de rotation ne portent atteinte à l'ajustement solide de la brosse à dents enfichable sur le bout d'arbre et à la fixation du pivot radial, afin que la brosse à dents ne puisse être démontée involontairement du bout d'arbre de la pièce de commande. The object of the invention is therefore to improve the electric hand appliance mentioned in the preamble, so that neither bending forces nor rotational forces affect the solid fit of the toothbrush. plugged onto the shaft end and to the radial pivot attachment, so that the toothbrush cannot be unintentionally removed from the shaft end of the control part.

Ce but est atteint, conformément à l'invention, par le fait que la paroi de l'évidement de la pièce qui constitue l'instrument comporte une ouverture entièrement lisérée, dans lequel est disposé au moins un cran d'arrêt, par le fait que ce cran d'arrêt est pourvu d'une denture dans laquelle l'ergot de la tige est encliqueté de manière détachable, et par le fait que la paroi de l'évidement entoure la tige sans interruption, devant et derrière l'ergot de celle-ci. This object is achieved, in accordance with the invention, by the fact that the wall of the recess of the part which constitutes the instrument comprises an entirely readout opening, in which is arranged at least one catch, by the fact that this catch is provided with a toothing in which the lug of the rod is detachably snapped on, and by the fact that the wall of the recess surrounds the rod without interruption, in front of and behind the lug of this one.

Du fait de la configuration de appareil à main
électrique selon l'invention, les fonctions "positionnement" et "fixation" sont totalement séparées l'une de l'autre. Etant donné que la paroi de l'évidement entoure sans interruption la tige devant et derrière un ergot, ce dernier est maintenu de manière sure et rigide. La section transversale de l'évidement correspond à la section transversale de la tige, seul un jeu minimal étant prévu, afin de permettre un glissement facile. La fixation de la tige a lieu à l'aide du cran d'arrêt dans la denture duquel l'ergot de la tige est encliqueté de façon détachable.
Due to the configuration of the handheld device
electric according to the invention, the "positioning" and "fixing" functions are completely separate from each other. Since the wall of the recess continuously surrounds the rod in front of and behind a lug, the latter is held securely and rigidly. The cross section of the recess corresponds to the cross section of the rod, only a minimum clearance being provided, in order to allow easy sliding. The rod is fixed using the stopper in the teeth of which the pin of the rod is detachably snapped.

Selon un mode de réalisation avantageux de l'invention, deux bras à ressort pouvant s'écarter de manière élastique l'un de l'autre, sont disposés de façon symétrique l'un par rapport à l'autre, et leurs extrémités libres sont élargies en forme de cames et enserrent l'ergot de la tige. According to an advantageous embodiment of the invention, two spring arms which can move elastically from one another, are arranged symmetrically with respect to each other, and their free ends are widened in the shape of cams and enclose the lug of the rod.

Outre les dispositions qui précèdent, l'invention comprend encore d'autres dispositions, qui ressortiront de la description qui va suivre. In addition to the foregoing provisions, the invention also comprises other provisions, which will emerge from the description which follows.

L'invention sera mieux comprise à l'aide du complément de description qui va suivre, qui. se réfère au dessin annexé dans lequel - la figure 1 est une vue d'une brosse à dents enfichable
et de l'extrémité d'une pièce de commande en forme de

The invention will be better understood with the aid of the additional description which follows, which. refers to the accompanying drawing in which - Figure 1 is a view of a pluggable toothbrush
and the end of a control piece in the form of
handle, from which the end of a rod comes out; - Figure 2 shows the plug-in end of the brush

I1 doit être bien entendu, toutefois1que ce dessin et les parties descriptives correspondantes, sont donnés uniquement à titre d'illustration de l'objet de l'invention, dont ils ne constituent en aucune manière une limitation. It should be understood, however, that this drawing and the corresponding descriptive parts are given solely by way of illustration of the subject of the invention, of which they in no way constitute a limitation.

La brosse à dents électrique comporte, d'une manière connue, une pièce de commande A réalisée en forme de poignée, et une brosse dents enfichable 2 comportant un manche en matière plastique 3. La tige 4 d'un moteur à armature oscillante logé dans la-pièce de commande'l, avance hors de l'extrémité du carter de la pièce de commande. La tige présente une section transversale rectangulaire et est munie, sur sa face plate, d'un pivot saillant 5. The electric toothbrush comprises, in a known manner, a control part A made in the form of a handle, and a pluggable toothbrush 2 comprising a plastic handle 3. The rod 4 of an oscillating armature motor housed in the control piece, advances out of the end of the control piece housing. The rod has a rectangular cross section and is provided, on its flat face, with a projecting pivot 5.

L'extrémité de raccordement du manche 3 dé la brosse comporte un évidement axial 6, dont la section transversale est adaptée à la section transversale de la tige, avec un jeu minimal. Dans la zone du pivot radial 5, la paroi latérale de l'évidement axial est interrompue de telle façon, lorsque la brosse à dents est montée, qu'il se forme deux petits bras élastiques 8 dont les extrémités libres sont pourvues de parties évasées 9. Les deux bras sont disposés de façon symétrique l'un par rapport à l'autre et peuvent s'écarter l'un de l'autre de manière élastique.Lorsqu'on introduit, la tige 4 dans l'evide- ment 6, le pivot 5 encliquette entre les deux bras 8, ce qui provoque la fixation du manche 3 de la brosse à dents sur la tige 4. I1 est à observer que l'ouverture 10 ne s'étend pas jusqu'à l'extrémité arrière du manche de la brosse à dents, en sorte que la paroi 7 de l'évidement entoure sans interruption la tige 4 devant et der rière l'ergot 5 de celle-ci. I1 se forme,ainsi, dans la zone d'embouchure de l'évidement 6, un anneau fermé qui n'est pas interrompu (comme c'est le cas dans les réalisations connues) par une fente pouvant s'élargir. I1 y a j-uste une rainure longitudinale 14 dans l'anneau 11 comme guidage du pivot 5 lorsque la tige 4 est introduite dans l'évidement 6. The connection end of the handle 3 of the brush has an axial recess 6, the cross section of which is adapted to the cross section of the rod, with minimal play. In the region of the radial pivot 5, the side wall of the axial recess is interrupted in such a way that when the toothbrush is mounted, two small elastic arms 8 are formed, the free ends of which are provided with flared parts 9 The two arms are arranged symmetrically with respect to one another and can move apart from one another in an elastic manner. When the rod 4 is introduced into the recess 6, the pivot 5 snaps between the two arms 8, which causes the fixing of the handle 3 of the toothbrush on the rod 4. It should be observed that the opening 10 does not extend to the rear end of the handle of the toothbrush, so that the wall 7 of the recess continuously surrounds the rod 4 in front of and behind the lug 5 thereof. I1 is thus formed in the mouth area of the recess 6, a closed ring which is not interrupted (as is the case in known embodiments) by a slot which can widen. There is a longitudinal groove 14 in the ring 11 as a guide for the pivot 5 when the rod 4 is introduced into the recess 6.

I1 est préférable de fabriquer le manche de la brosse à dents en matière plastique par le procédé par injection, l'ouverture 10 et les bras élastiques 8 étant formés en même temps. It is preferable to manufacture the handle of the plastic toothbrush by the injection process, the opening 10 and the elastic arms 8 being formed at the same time.

Dans le mode de réalisation suivant les figures 4 et 5, une traverse de raccordement 12 axiale élastique est placée au centre de l'ouverture 10 ; cette traverse comporte une denture 13 dans laquelle le pivot 5 de la tige peut encliqueter. In the embodiment according to FIGS. 4 and 5, an elastic axial connection cross member 12 is placed in the center of the opening 10; this crosspiece has a toothing 13 in which the pivot 5 of the rod can snap into place.

Lors du fonctionnement de la brosse à dents êlec- trique, le manche de la brosse, qui se trouve en alignement rectiligne avec la tige de commande, exécute un mouvement oscillant autour de son axe longitudinal. Si des efforts de rotation ou de flexion se produisent entre le manche et la tige, ces efforts sont transmis intégralement par l'évidement de positionnement 6, qui est rigide et qui ne permet donc aucun flambage ni aucune perte d'élasticité du raccord par insertion. Conformément au guidage rigide de la tige, seuls des efforts longitudinaux peuvent se produire entre la tige et les bras élas tiques du manche de la brosse, tels que les efforts nécessaires pour insérer et détacher le manche. Tous les autres efforts de rotation et de flexion ne sont pas transmis aux bras élastiques en sorte que leur action de fixation ne soit pas compromise. During the operation of the electric toothbrush, the handle of the brush, which is in straight alignment with the control rod, performs an oscillating movement around its longitudinal axis. If rotational or bending forces occur between the handle and the rod, these forces are transmitted entirely by the positioning recess 6, which is rigid and which therefore does not allow any buckling or any loss of elasticity of the fitting by insertion . In accordance with the rigid guide of the rod, only longitudinal forces can occur between the rod and the elastic arms of the handle of the brush, such as the forces necessary to insert and detach the handle. All other rotational and bending forces are not transmitted to the elastic arms so that their fixing action is not compromised.

Ainsi que cela ressort de ce qui précède, l'invention ne se limite nullement à ceux de ses modes de réalisation et d'application qui viennent d'être décrits de façon plus explicite ; elle en embrasse au contraire toutes les variantes qui peuvent venir à l'esprit du technicien en la matière, sans s'écarter du cadre, ni de la portée, de la présente invention.  As is apparent from the above, the invention is in no way limited to those of its embodiments and of application which have just been described more explicitly; on the contrary, it embraces all the variants which may come to the mind of the technician in the matter, without departing from the framework, or the scope, of the present invention.
