Abstract

Clutch mechanism, especially applicable to helical fans, in order to govern the stoppage or operation of the mechanism that determines the angular movement of oscillation of these apparatuses, characterized by comprising an axis mounted on corresponding fixed supports, so that it can rotate freely and can move in the axial direction between two conveniently established limit positions, with movements determined through an external maneuvering member, whose axis comprises a pinion which is constantly engaged with the attack pinion, the oscillation mechanism, has a diametrical opening in the that are lodged two balls constantly driven to excel by the action of a coil spring interposed between them, and freely crosses the axial opening of a pinion constantly coupled to the axis of the electric motor of the device, having provided in one of the fixed supports that are crossed by the expressed axis an annulartern race in which, in one of the limit positions that can be adopted, the referred balls fit, and in the axial opening of the pinion a recess, in which, in the opposite limit position of the pinion, can fit a to be balls; all in such a way that the repeated balls determine the retention of the axis in the limit position in which each case is located, and that in the first of these positions the axis is released with respect to the pinion coupled to the electric motor, without consequently transmitting the movement of the same to the oscillation mechanism, while in the second limit position the axis and the pinion are fixed in rotation, actuating that to the expressed mechanism.
