Il est donc nécessaire que tout dispositif de commande à-levier utilisé en quantités importantes soit conçu pour être fabriqué de façon simple Entre autres choses, la limitation de coût impose essentiellement une conception It is therefore necessary that any lever-operated control device used in large quantities is designed to be manufactured in a simple manner. Among other things, the cost limitation essentially imposes a design

These elbows are subject to the appearance of high stress points at which a failure may occur. Thus, reliability can be improved by avoiding the use of torsion springs. and / or traction Another disadvantage of the conventional device described above is its relatively high number of

Comme représenté sur les figures 4 et 5, la surface 20 de came est configurée de manière que sa section radiale par rapport à l'axe 14 présente la forme d'un arc de cercle. Un suiveur de came ou une contrecame 22, se présentant sous la forme d'un manchon présentant une surface conique 23, est monté sur le manche Il afin de pouvoir coulisser le long de l'axe 14 La surface 23 est une surface de révolution autour de l'axe 14 La surface de came, qui est également illustrée sous la forme As shown in FIGS. 4 and 5, the cam surface 20 is configured so that its radial section with respect to the axis 14 has the shape of a circular arc. A cam follower 22 or countercam, in the form of a sleeve having a conical surface 23, is mounted on the handle 11 in order to slide along the axis 14 The surface 23 is a surface of revolution around of the axis 14 The cam surface, which is also illustrated in the form

Un ressort à boudin 24 entourant le manche il est comprimé entre le suiveur de came 22 et un élément de retenue fixé au manche 11 Le ressort 24 constitue un élément de rappel qui rappelle ou tend à déplacer le suiveur de came 22 vers le point 17 d'articulation Par conséquent, le ressort 24 tend à loger le suiveur de came 22 dans l'ouverture 19 pour placer le manche Il en position centrée La surface de came 20 permet au suiveur de came 22 de se rapprocher au maximum ou d'arriver à une distance minimale du point 17 d'articulation lorsque le manche 11 est en position centrée Comme montré sur la figure 3, lorsque l'on fait pivoter le manche 11 à l'écart de la position centrée, dans une direction quelconque orientée transversalement à l'axe 14, la surface 20 de came a pour effet d'éloigner le suiveur 22 du point 17 d'articulation contre la force du ressort 24 Inversement, le ressort 24 tend conjointement avec le suiveur de came 22 et la surface de came 20 à ramener le manche 11 vers A coil spring 24 surrounding the handle is compressed between the cam follower 22 and a retaining element attached to the handle 11. The spring 24 constitutes a biasing element which recalls or tends to move the cam follower 22 towards the point 17 of the cam. As a result, the spring 24 tends to accommodate the cam follower 22 in the opening 19 to place the handle 11 in a centered position. The cam surface 20 allows the cam follower 22 to move as far as possible or to arrive at the cam follower 22. a minimum distance from the articulation point 17 when the handle 11 is in the centered position As shown in FIG. 3, when the handle 11 is pivoted away from the centered position, in any direction transversely oriented to the 14, the cam surface has the effect of moving the follower 22 from the hinge point 17 against the force of the spring 24. Inversely, the spring 24 tends in conjunction with the cam follower 22 and the cam surface 20. bring back the 11th round

La suspension 13 à la cardan constitue un exemple d'un type de dispositif de montage permettant un mouvement de pivotement sur deux axes transversaux. Elle comprend un anneau 30 qui peut pivoter sur le manche 11 au moyen de broches convenables 31 alignées sur l'axe 16 L'anneau 30 peut également pivoter sur la-plaque 12 au moyen d'équerres 32 qui sont fixées à la plaque 12, et de broches convenables 33 alignées sur l'axe 15 et portant l'anneau 30 afin qu'il puisse pivoter entre les équerres 32 Par conséquent, le manche 11 peut pivoter indépendamment autour des axes 15 et 16 Cependant, il convient de noter que, bien qu'un support à suspension à la cardan soit représenté, d'autres types de supports The cardan suspension 13 is an example of a type of mounting device for pivotal movement on two transverse axes. It comprises a ring 30 which can pivot on the handle 11 by means of suitable pins 31 aligned on the axis 16 The ring 30 can also pivot on the plate 12 by means of brackets 32 which are fixed to the plate 12, and suitable pins 33 aligned on the axis 15 and carrying the ring 30 so that it can pivot between the brackets 32 Therefore, the handle 11 can pivot independently about the axes 15 and 16 However, it should be noted that, although a cardan suspension support is shown, other types of supports
