Such a locking device is from the DE 10 2004 001 712 A1 known.

The locking device in question has the task of a gate in addition to to block an inhibitory effect by a door drive.

The Invention is particularly in the field of so-called swing gates and swing gate operators. As revolving gates are in the field of gate technology designates such goals, which have one or more wings, which are similar as usual room doors are laterally mounted on hinge devices such that they around a defined by the hinge device vertical axis for opening and closing and swing her. A distinction to doors is made such that such gates are so big that they can close entrances of two-lane vehicles.

Such Swing gates are common at property entrances of private land or industrial property. Due to the motion kinematics such Drehtorflügel are the drive devices are always arranged close to the hinges, because the to be closed Driveways must remain passable.

It is generally state-of-the-art for door drives, these are self-locking perform. In the closed position of the gate is the gate connected to the door drive so by the self-locking held the door drive. This can be the case of larger gates of swing gates because of the large lever arm a force acting on the free end does not always lead to a sufficient closing effect to lead. Violent action or wind influences on the gate can at especially wide swing door wings so to damage lead the self-locking drive.

It is therefore already prior art and for example from the aforementioned DE 10 2004 001 712 A1 it is known to additionally provide a locking device on the door leaf when the swing door leaves are driven. In order not to ruin the advantage of the convenient automatic opening by a swing gate operator again, such locking devices to be used in connection with door drives are provided with an automatic or remote-controlled lock.

The DE10 2004 001 712 A1 describes for this purpose an electric lock in which a locking element is biased in its locking position. opposite this bias is the locking element by means of an electric Coil retractable. The power to retire must then be provided by the door operator control. This must in the known control devices and swing gates during the entire swing door wing movement happen so that they are not biased by the in its locking position Locking element disturbed becomes. In the known electric lock are for this purpose in the Electric lock special measures taken with which the locking element during the driven movement reliable can be held in its unlocked position.

To open the gate 57 first, the door drive control (not shown) drives the electric lock 14 on, this pulls the flycatcher 16 back. When the catch is withdrawn, a swing gate drive is then activated to move the gate leaf. Has the gate from the in 5 moved to be locked position, the electric lock 14 be switched off; The catch snaps back out of the electric lock 14 out. The gate wing 57 can then with extended Schnäpper 16 be moved over the entire doorway.

When returning, the door drive drives the gate 57 on until the stop roller 32 over the run-up slope 52 on the flat Abrollfäche 58 is driven. Here then drives the stop roller 32 Continue driving until you are against the stop 44 encounters. During this movement, a rounded area is detected 66 at the free end of the flycatcher 16 the run-up slope 52 , wherein the catch against a spring preload in the lock housing 20 is pushed back. Get the flycatcher 16 then upon detection of the stop 44 through the stop roller 32 about the depression 50 , the snap snaps into the 5 shown locking position back.

The stop role 32 is made of elastic material, such as rubber material, formed, and thus dampens the impact against the stop 44 and can also provide a resilient bias of the latch 16 against the counter bearing 46 and thus a stable, low-vibration locking position of the door leaf 57 cause. How out 5 can be seen, in the locked state, all screws and fasteners 22 . 24 . 26 . 38 arranged in a covert area and not accessible. The screws 26 for fastening the lock housing 20 are only after opening the lock housing 20 accessible via a key.
