Patent

CA 2504522

The invention proposes a device (20) comprising a housing (22), a revolving shaft (44, 46) rotated by a drum (36), and a rotary signals generator (100, T6), of the type in which the shaft is mounted such that it is vertically movable and tilts in both directions so as selectively to provoke the triggering of a first switching way when a force is applied to the center (38) of the drum (36), or of a second and a third switching way when a force (F2, F3) is applied in the vicinity of one or other (40, 42) of the two ends of the drum (36), characterized in that the drum (36, 41, 43) rests vertically directly on a central member (30, 131, B2, 133) common to the three switching ways, which bears upon the bottom (56, 28) of the housing (22) and which, from a rest position, is selectively elastically deformable under the action of one of the vertical orientation forces (Fl, F2, F3).

L'invention concerne un dispositif (20) qui comprend un logement (22), une tige rotative (44, 46) mise en rotation par un tambour (36), et un générateur rotatif (100, T6) de signaux. La tige est montée de façon à être déplacée dans le sens vertical et s'incline dans deux sens afin de provoquer sélectivement le déclenchement d'une première voie de commutation lorsqu'une force est appliquée sur le centre (38) du tambour (36), ou d'une deuxième et d'une troisième voie de commutation lorsqu'une force (F2, F3) est appliquée à proximité d'une ou de l'autre (40, 42) extrémité du tambour (36). Ce dispositif est caractérisé en ce que le tambour (36, 41, 43) repose directement de manière verticale sur un élément central (30, 131, B2, 133) commun aux trois voies de commutation qui repose sur le fond (56, 28) du logement (22) et qui, depuis une position de repos, peut sélectivement subir une déformation élastique sous l'effet d'une des forces d'orientation verticales (F1, F2, F3).
