so that the motor 30 is held in place and on top of the gear shaft 31 pressed on eccentric lever 32 the pressure roller pushes the pull lever 34 downwards. The pulling rollers pull the chain or the rope 6 over the pulleys 8 down, so that in the area of the fastening point 7 on the right door the rope 6 is shortened and the door 4 is raised into the closed position. When the door is in the closed position, it has 4 the eccentric lever 32-executed a rotation through 180 °, wherein the pull lever 34 is in the lower position indicated by dash-dotted lines. In this position, the j pressure roller 33 is applied to the lower switch 19, which switches off the electromagnet 18. Both are in this state Doors 4 and 5 closed.

BG9822 / 0103

By switching off the electromagnet 18, the locking rod 14 is shifted to the right by the compression spring 17, wherein
it slides under the closed door 4 and at the same time j releases the left door 5. As long as the pull lever 34 is in the: lowered position, the left-hand side is enough; Not enough rope length so that the door 5 can move into the open position. This is made possible by the fact that the eccentric lever 32 continues clockwise into the position shown in FIG the reproduced starting position rotates back, gradually the rope length required to open the door 5 is released j. The dead weight of the door 5 lowers it from j and at the same time pulls the pull lever 34 upwards. When the door 5 is in the open position, the pressure roller 33 is again
reached the position shown, the switch 35 is actuated and the motor 30 is switched off.

If the right door 4 is then to be opened again, the result is
ι after pressing the button on the control panel for
J the engine control the same sequence, whereby through the pressure ".
■; roller 33 the pull lever 34 is lowered and the door 5 is
; is closed. After reaching the closed position, the
Switch 19 is applied to switch on the electromagnet 18; of the locking bar 14 under the closed door 5
pushes while at the same time the still closed door 4
is unlocked. By turning the pressure roller 33 back into the
Starting position, the pull lever 34 is again raised by the weight of the opening door 4.

If the safety flap 20 is pivoted inward when the door 5 is closed, the switch 36, which controls the motor 30, is actuated
switches off and reverses the direction of rotation. The door 5 is thereby moved back into the open position, so that in no case
an injury on the customer side is possible. The recess 22 provided in the stop part 21, into which the door 5 in
engages in the closed position, prevents in the closed
Door an unauthorized actuation of the safety switch 36. The
Safety flap 20 can also be operated when

there is a package between the door 5 and the flap when it is started up.

Should the safety switch 36 fail, the door 5 cannot close when the flap 20 is in a Pivoting position is because it comes to rest against the curved portion of the stop part 21. Here too will prevents injury. Since the door 5 has not yet reached the highest position in this case, and so has the eccentric lever 32 is not yet pivoted down so far that the switch 19 is acted upon, an unlocking is here the still closed door 4 is not possible.

The motor 30 is expediently also provided with adjustable overload protection, so that it is absolutely safe j is given against injuries.

j In the embodiments according to FIGS. 1 and 2 with foot lever actuation the stop part 21 in a pivoted position of the flap 20 also unlocks the still 'Prevents closed opposite door. To prevent injuries on the bank side, it is sufficient in the As a rule, a simple pivotable flap 20, as shown in FIG. 3, should be provided. A pinch of the hand is thereby prevented that the right door 4 is in the closed position at a distance from the upper edge of the hatch 2 is located, this remaining gap being covered by the flap 20.

Various modifications of the construction described are possible. 4 shows schematically another embodiment. The rope 6 connecting the two doors 4 and 5 is wound in at least one turn around a drum 37 which is rotatably mounted in the counter and which can be driven, for example, by an electric motor. The rope length is designed so that on one side of the drum 37 the rope is essentially tensioned when the two doors 4 and 5 are in the

[-Closed position, be inden, _xähr_end..da.s_seeil_ on each ^ opposite-

809852/0103 - 12 -

overlying side of the drum sags loosely. Is going out of this operating state the left "door 5 is unlocked and the right door 4 locked, for example by means of a locking rod 14, as in the previous embodiments has been described, the door 5 can lower itself into the open position without the drum 37 j is twisted further. To close the door 5 is then the j drum 37 rotated clockwise until the closed position of the door 5 is reached, at the same time on the right Side forms a loosely sagging piece of rope. After unlocking the door 4 and locking the door 5, the Open door 4 due to its own weight. In such a configuration, the shortening and lengthening of each required rope length instead of the pulleys 10, vorgej according to FIGS. 1 to 3, the rotatable rope drum 37 see.

According to another embodiment, the two doors I 4 and 5 can also be opened in the specified manner via a linkage! opens and closes. It is also possible to operate the doors with a pneumatic or hydraulic actuation ^; ! to move the cylinder into the open and closed position, where \ j z. B. such a cylinder can be arranged on each door and the two cylinders are switched so that one can only be actuated when the other is in the position that corresponds to the closed position of the associated door. In such a configuration it is not necessary to connect the two doors 4 and 5 to one another via a chain or a rope or a linkage.

In the construction described in FIGS. 1 to 3, the pull lever 11 or 34 can also be pneumatic or hydraulic cylinder or pivoted via a linkage will.

j In a more complex device, each door can have an electric motor for the opening and closing movement be assigned to the door via a separate cable or for example

'809822/0103 - 13 -

also moves via a rack. The two motors can be switched so that one can only be switched on when the other is in the closed position. With such a configuration, too, there is no mechanical connection between the two doors 4 and 5 and a mechanical locking device can also be omitted. j

I The locking device is preferably as a continuous ■ - \ locking bar formed as shown in Figures 1 to, but also separate latches on the j two doors may be provided. If the pull lever 11 or 34 j is installed in the counter so that it can pivot horizontally, it is preferably spring-loaded in one pivoting direction. In the ¹ embodiment of FIGS. 1 to 3 with a vertical pivot; direction of the pull lever 11 or 34, a spring can be omitted! which pushes the pull lever upwards as it is pushed by the weight; the opening door is pivoted upwards.

i Finally, manual operation of the bulletproof penetration
