<p>The door-leaf is supported and guided by at least one runner-roller (27) along a rail (25) along which it is moved by means of a drive motor. The drive motor and at least one runner-roller are contained in a running carriage (28) joined to the door leaf. The drive motor is connected to a cog wheel (35) rotating on a vertical pivot axle (36) and cooperating with a row of teeth along the rail. For power transmission from the cog wheel to the row of teeth, contact points (40,41) are vertical for load application of the runner-roller onto the rail.</p> |
