Abstract:
1. A linear actuator for a closure element having two jambs and a sliding leaf, the linear actuator comprising a box body, fixing elements for fixing said box body between the two jambs of the closure element, in order to move the leaf by translational motion, a fixed drive accommodated within said box body, said fixed drive being adapted to move corresponding transmission elements connectable to said sliding leaf, said box body being telescopic in structure in order to be adapted in length to a width of a space between the two jambs, said fixing elements comprise at a first end of said box body: said fixing elements comprising at a second opposite end of the box body: said adjustor for the adjustment of the fixing distance between said first end of said box body and the surface of the leaf of the door comprise a block, defined by a first end of a plug, arranged in said first end of the box body, containing a plurality of parallel seats arranged side by side for said tab, the choice of the seat in which to insert said tab determining the distance between said box body and a facing underlying surface of the leaf of the door, wherein said pivoting connection comprises a through hole defined so as to pass through said plurality of seats on said first part of said plug, for joining, with a screw, said tab to said first part so that the box body can perform angular movements about the axis of said screw prior to fixing the second end of said box body to the rail.
