Abstract
A control arrangement with a single lever pivoting successively about two articulation axes. The lever is articulated on a fixed plate by the intermediary of at least one link. The link is articulated on the plate at a fixed axis while the lever is articulated on the link at an axis movable with respect to the plate and offset from the fixed axis. In this way, after the lever-link assembly has pivoted around the fixed axis, the link comes up against a stop on the plate so that the movable axis becomes fixed in its turn and the lever continues its travel pivoting about this axis.
Claims5
A multiple-command device for cable control of the air conditioning elements of an automobile comprising:
- a mounting plate immovably fixed to said automobile;
- a control lever;
- at least one link articulated on the plate by a fixed axis serving as pivot for the lever and also articulated on the lever by an axis movable with respect to the plate and offset with respect to the fixed axis, the lever being articulated on the plate successively about said two axes by the intermediary of said at least one link;
- at least one control cable attached to said at least one link;
- a stop on the plate, the movable axis being rendered momentarily fixed by the stop, said at least one link coming to rest against the stop in the course of the excursion of the lever so that the movable axis becomes a new pivot for the rest of the travel of the lever.
A multiple-command device for cable control of the air conditioning elements of an automobile comprising:
- a mounting plate;
- a control lever;
- an upper link;
- a lower link;
- each link articulated, on the one hand, on the plate by a fixed axis serving successively as pivot for the lever and, on the other hand, on the lever by an axis movable with respect to the plate and offset with respect to the fixed axis, the lever being articulated on the plate successively about the two axes between the two links;
- a plurality of control cables attached to the links;
- a pair of stops on the plate, each movable axis of a link being rendered momentarily fixed and coincident with the fixed axis of the other link when the first link comes up against its respective stop integral with the plate.
