Abstract

The switching device consists of a switching element (4), which is inserted into an opening in the housing wall (1a), is constructed such that it can be displaced and tipped, and is provided with a rotation shaft (5). The one end (6a) of a rod (6) which can be displaced in its longitudinal direction is connected in a hinged manner to the rotation shaft (5). The other rod end (6b) is connected to the switch (7) of the drive motor (3) via a spring (8). The part (4b) of the switching element (4) facing the front rod end (6a) is supported on a projection (9) of the housing wall (1b) when the motor is switched off. When the sliding switching-on movement takes place, said part is guided over the edge of the projection (9) and hence tips downwards about the rotation shaft (5).

Description

La présente invention se rapporte à un dispositif de commande du moteur d'un instrument électrique. The present invention relates to a device for controlling the motor of an electric instrument.

On connaît des instruments électriques dont les composants essentiels, tels que le moteur, la transmission, I 1inter- rupteur sont logés dans des chambres formées dans un boitier en matière plastique composé de deux coquilles. Cet instrument électrique sert de machine d'entraînement et peut être accouplé à des dispositifs auxiliaires tels que des dispositifs de perçage et d'affûtage. Les instruments électriques de ce genre sont généralement conçus pour être utilisés d'une seule main et comportent, en conséquence, sur le coté extérieur du boitier, un organe de commande pour mettre en marche et arrêter le moteur. Ces organes de commande ont, toutefois, l'inconvénient qu'ils sont difficiles, sinon impossibles à manoeuvrer avec la main tenant l'instrument, de sorte que celui-ci doit être mis en marche et arrêté avec l'autre main.Or, il arrive parfois que l'utilisateur d'un tel instrument électrique soit dans une situation qui l'oblige à se tenir avec l'autre main, de sorte qu'il est incapable d'utiliser cette main pour mettre en marche et pour arrêter 1 'ins- trument. Electric instruments are known of which the essential components, such as the engine, the transmission, the switch are housed in chambers formed in a plastic casing composed of two shells. This electric instrument serves as a driving machine and can be coupled to auxiliary devices such as drilling and sharpening devices. Electric instruments of this kind are generally designed to be used with one hand and consequently have, on the outside of the case, a control member for starting and stopping the engine. These control members have, however, the disadvantage that they are difficult, if not impossible to operate with the hand holding the instrument, so that it must be started and stopped with the other hand. it sometimes happens that the user of such an electric instrument is in a situation which obliges him to hold himself with the other hand, so that he is unable to use this hand to start and to stop 1 'instrument.

Le but de la présente invention est d'apporter un dispositif de commande pour un instrument électrique du type spéci fié ci-dessus qui permet de mettre en marche et d'arrêter le moteur sans le secours de la seconde main. The object of the present invention is to provide a control device for an electric instrument of the type specified above which makes it possible to start and stop the engine without the help of the second hand.

L'invention atteint les buts qu'elle s'est fixés en ce que l'organe de commande est un elément pouvant coulisser et basculer et qui est pourvu d'un axe de rotation, avec lequel l'une des extrémités d'une tige pouvant coulisser longitudinalement est articulée, l'autre extrémité de ladite tige étant reliée, par l'intermédiaire d'un ressort à l'interrupteur du moteur et en ce que la partie de l'organe de commande orientée vers l'extrémité antérieure de la tige repose, lorsque le moteur est arrêté sur un prolongement de la paroi du boitier, la disposition étant telle que pendant le mouvement de coulissement pour la mise en marche du moteur, cette partie glisse au dessus du bord du prolongement et, ainsi, bascule vers le bas autour de l'axe. The invention achieves the goals which it has set itself in that the control member is an element which can slide and tilt and which is provided with a rotation axis, with which one of the ends of a rod which can slide longitudinally is articulated, the other end of said rod being connected, by means of a spring to the engine switch and in that the part of the control member oriented towards the anterior end of the rod rests, when the engine is stopped on an extension of the wall of the box, the arrangement being such that during the sliding movement for starting the engine, this part slides over the edge of the extension and, therefore, switches to the bottom around the axis.

Le dispositif selon l'invention offre l'avantage de permettre, dans toutes les situations, d'arrêter rapidement le moteur sans le secours de l'autre main en posant simplement le moteur électrique sur l'organe de commande ou en appuyant ce dernier contre un corps fixe.  The device according to the invention offers the advantage of making it possible, in all situations, to quickly stop the engine without the assistance of the other hand by simply placing the electric motor on the control member or by pressing the latter against a fixed body.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, en réference au dessin annexé, sur lequel
La figure 1 est une vue latérale, partiellement en coupe, d'un instrument éléctrique pourvu d'un dispositif de commande conforme à l'invention,
la figure 2 est une vue en plan sur une partie de 1 'ins- trument de la figure 1 , et,
la figure 3 est une vue en coupe à plus grande échelle du détail A de la figure 1.Other characteristics and advantages of the invention will emerge from the description which follows, with reference to the appended drawing, in which
FIG. 1 is a side view, partially in section, of an electric instrument provided with a control device according to the invention,
FIG. 2 is a plan view on part of the instrument of FIG. 1, and,
FIG. 3 is a sectional view on a larger scale of the detail A of FIG. 1.

L'instrument électrique représenté sur le dessin comprend un bottier en matière plastique 1 dont la face supérieure présente une ouverture 2 dans laquelle est monté un organe de commande 4. L'organe de commande 4 est un organe pouvant coulisser et basculer et comporte un axe de rotation 5. Une tige 6, pouvant se déplacer longitudinalement, est articulée à cet axe 5, c'est à dire que l'extrémité 6a de ladite tige et l'axe 5 forment une articulation à fourche a cgté des parties 4a de l'organe de commande portant leurs paliers. L'autre entré mité 6b de la tige 6 est reliée à un ressort 8, logé dans l'interrupteur 7 du moteur 3 et qui exerce une pression dans la direction de la flèche B.La partie 4b de l'organe de commande 4 orientée vers l'extrémité 6a de la tige 6 repose, lorsque le moteur 3 est arrêté, sur un prolongement 9 de la paroi la du boîtier et, pendant le mouvement de mise en marche du moteur, elle glisse au-dessus du bord du prolongement 9 en surpassant la force du ressort 8. The electric instrument shown in the drawing comprises a plastic case 1, the upper face of which has an opening 2 in which is mounted a control member 4. The control member 4 is a member that can slide and tilt and has an axis of rotation 5. A rod 6, which can move longitudinally, is articulated to this axis 5, that is to say that the end 6a of said rod and the axis 5 form a fork articulation cgté parts 4a of l 'control member carrying their bearings. The other mite input 6b of the rod 6 is connected to a spring 8, housed in the switch 7 of the motor 3 and which exerts pressure in the direction of the arrow B. The part 4b of the control member 4 oriented towards the end 6a of the rod 6 rests, when the motor 3 is stopped, on an extension 9 of the wall la of the housing and, during the movement of starting the motor, it slides over the edge of the extension 9 by exceeding the force of the spring 8.

Pendant cette opération, la partie 4b bascule vers le bas autour de l'axe 5, de sorte que la partie 4c de l'organe de commande 4 s'élève au-dessus de la paroi la du bottier (comme représenté en tirets). During this operation, the part 4b swings down around the axis 5, so that the part 4c of the control member 4 rises above the wall la of the bootmaker (as shown in dashes).

Pour assister le mouvement de basculement de l'organe de commande 4 pendant la mise en marche du moteur, on peut, comme représenté sur la figure 3, fixer à la partie 4b basculant vers le bas, l'une des extrémités d'un ressort de tension 10 dont l'autre extrémité est fixée sous un prolongement de la paroi la du boîtier s'étendant sous l'organe de commande 4.  To assist the tilting movement of the control member 4 during the starting of the engine, it is possible, as shown in FIG. 3, to fix to the part 4b rocking downwards, one of the ends of a spring of tension 10, the other end of which is fixed under an extension of the wall 1a of the housing extending under the control member 4.

Toutefois, il est également possible d'aider le basculement de organe de commande 4 au moyen d'un ressort de compression judicieusement monté. However, it is also possible to assist the tilting of the control member 4 by means of a judiciously mounted compression spring.

Quand l'organe de commande 4 occupe la position esquissée en tirets, le moteur 3 est en marche et pour l'arrêter il suffit de poser l'instrument électrique avec sa face supérieure tournée vers le bas, de sorte que la partie saillante 4c de l'organe de commande est repoussée dans le plan de la paroi la du bottier, ramenant ainsi cet organe de commande dans sa position de départ. When the control member 4 occupies the position sketched in dashes, the motor 3 is running and to stop it it suffices to place the electric instrument with its upper face facing downwards, so that the projecting part 4c the control member is pushed back into the plane of the wall la of the bootmaker, thus bringing this control member back to its starting position.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être decrit et représenté. On pourra y apporter de nombreuses modidifications de détails sans pour cela sortir du cadre de l'invention.  Of course, the invention is not limited to the embodiment which has just been described and shown. Many modifications of details can be made without departing from the scope of the invention.
