Mechanical door-opening and door-closing device for 2-wing and 1-wing structural members, such as doors, gates, windows etc., as stipulated in Claim 1, such that in the case of a 2-wing door having an opposed pivot region (Figure 1) (2), a driving force (1) which is introduced in the floor below the side of the lock in the closed position is arranged in such a way that the pivot region boundary (2) of the door wing (7) is to be intersected from this stationary point by means of a link chain (3) in the chain casing (Figure 2) (11) or a connecting rod, spindle etc. at an angle of approximately 45 DEG , the carrier web (5) extends with a sliding connection through the floor slot (14) with the running roller (4) in the running rail (6) on the door wing (7) and it is possible to transfer the sequence of movements to the other door wing (9) in a symmetrical fashion by means of a cross-like articulation (8). As an extension of this door-opening and door-closing device according to Claim 1, a connecting flap (Figure 3) (12) extends through the floor slot (Figure 2) (14) as far as the movable articulation (13) on the lower door leaf edge (7) and the sequence of movements according to Claim (1) can be transferred to the other door wing (9) in a symmetrical fashion. <IMAGE> |
