The invention relates to a rack (1) for electromechanical operating systems of doors, gates and the like, which is formed in a modular manner by a series of toothed segments (2) connected together by means of respective tenon (3) and mortise (4) (ends). Advantageously the toothed segments have, formed underneath the profile of their teeth, recesses (7) wherein there are inserted matching projections (22) provided on brackets (20) to be fixed on the doors. The rack thus constructed may be easily adapted to, and mounted on, doors of any size. <IMAGE> |
