Swinging-sliding door for vehicles

A swinging-sliding door for vehicles, particularly passenger vehicles, each such vehicle having a wall structure, and door posts comprising:

• a telescopic guide rail means (5) mounted by means of sviwel arms (6,7) to the wall structure, and being provided for holding the rail means when moving into and out of the wall structure;
• at least one door leaf positioned for being outside and within the wall of the vehicle, respectively in an open and in a closed state for the door, said leaf being guided by the guide rail means for moving along the wall when the door is moved into the open state;
• additional top and bottom rails (35,36) on the door leaf;
• a driving device for operating the door leaf,
• the driving device including at least one pivotable, roller carrying lever mounted on one of the door posts said lever swings the guide rail means and the door leaf from the closed position of the door leaf into a ready-to-open position that is into a plane outside the wall structure as the rollers run in the additional rails,
• the driving device including an electro-motor (33) and gearing unit (37) and a drive pulley connected to the gearing unit for being driven by the gearing unit when the motor runs, the motor and gearing unit being positioned laterally above the opening of the door,
• the driving device further having a case which turns as a result of reaction when the motor runs,
• a traction means also included in the driving device and being connected to the pulley and being guided through a deflection pulley and connected to the door leaf for thereby drivingly coupling the drive pulley to the door leaf for shifting the leaf along the wall on turning of the drive pulley;
• said case having a flange carrying an eccentric control pin and turning the pin on turning of the flanges as a result of the reaction when the motor runs
• a control lever fastened to the door post, the control lever having a slot of a curved contour engaging the pin so that upon turning of the flange the pin moves the control lever which in turn turns the post to thereby pivot the roller carrying lever;
• and
• said control pin (16,17) in a door closing position being held in a dead center position in the curved contoured control lever so that the door is safely locked and can neither be opened manually nor by forces of the wind, the driving device through the flange exerting a reaction force onto the control lever which for a door opening results in the reaction force and turning of the pin and of moving the control lever to thereby unlock the lever so that the door leaf is permitted to be moved out of the plane of the wall permitting further sliding opening of the door through the traction means.
