Driving device for sliding doors |
(57) The driving device for sliding doors, comprising a rack (1) integral with the sliding
door, a driving pinion (2) engaged with said rack (1) driven by a motor (3) integral
with said pinion (2), that is vertically movable, and it is
characterised in that the pinion (2) or the motor (3) are linked with a spring (4) that presses said pinion
(2) against the rack (1), engaging the pinion (2) with the rack (1).
It permits to guarantee a pressure engagement of the pinion with the rack and permits
to absorb the irregularities in the height of the rack, permitting therefore the fixation
of the rack to the sliding door to be carried out at the factory, that guarantees
a better quality and a decrease of the cost, because the final adjustment is not carried
out at the building site.
