Description

The invention relates to a lock according to the preamble of claim 1.

In DE 37 37 151 C2, which is used to delineate the invention is a locking device for a hand-operated double-leaf door shown, with a passive leaf and a moving leaf, with the help of a closing sequence controller in the order of passive leaf, active leaf in the closed position acted upon are, with a transition wing-side actuation lock, wherein at least in each case engages a closing element in the head and bottom side frame parts and from the active leaf is actuated. In this case, at least one closing element the locking arranged on the active leaf and with the other closing element directly actuated by the mechanism of the actuating lock.

A disadvantage of this arrangement is that an automatic locking and unlocking not possible. Thus, it is not possible an automatic door drive to use. The door can therefore especially in escape and rescue routes not automatically release an escape route and after an alarm also automatically close again and then lock in to prevent burglary.

EP 02 88 454 A2 shows a locking device for a two-leaf Door, with a fixing device for locking one of the two door leaves opposite the door frame and a handle-operated latch lock to the mutual Locking both doors, with the fixing device and the latch lock are arranged on the same door, and the fixing of a in the area the edge of the upper edge of the door edge is made by the Operation of the latch lock lever simultaneously with the case of the Fallenschlosses against a spring force from the closed position into an open position is retractable.

The disadvantage is that the door is not used as an outer door in escape and rescue routes can be, since no burglar-resistant locking takes place and the Fixing device consists only of a Kantenschnäpper, easily manipulated is and can be pushed back against the spring in the wing, and thus the wings can be pressed. An automatic locking and unlocking is also not possible, whereby no automatic door drives used can be.

Also known are latches for two-leaf revolving doors, the aisle wing a single-lance lock and the inactive leaf has a driving bolt lock, and the wings are guided by door closer into their closed position. A floating bolt lock has vertical bars, which the wing in the ground and in lock upper door frame, with the rods there in corresponding recesses or intervene holes. The door closers have a closing sequence control on, whereby a closing of the active leaf only after closing the Still wing takes place and thus closed the wings in the correct order become.

To secure the exterior of buildings in escape and rescue routes, is a burglar-proof Lock required. For this it is necessary that the bolt in engages the strike plate and keeps the door locked.

A committing in escape direction must be in accordance with the regulations at any time can be done by a handle. Therefore, so-called panic locks used, which on actuation of the handle from the inside the latch and retract the latch at the same time. When the handle is operated from the outside the door remains locked because the outer fitting does not lock with the lock mechanism connected is.

When committing to the active leaf in the direction of escape, the trap and the bolt is pushed back and the leaf can be opened, the inactive leaf remains closed on the bolt lock. The escape route is so far only partially released. If the fitting of the passive leaf is actuated, the drive bolt rods are pulled into the fitting and the latch and the bolt are pushed back through the so-called counter box into the lock in the moving leaf, whereby both wings can be opened.
The disadvantage here is that when the fitting of the active leaf of the inactive leaf remains locked and the escape route is only partially released. A complete automatic opening in case of danger, to allow a free passage or a smoke outlet, and an automatic closing and locking after the danger can not be done in the known locks in this way.

Also known are motorized locks for single-leaf doors, wherein an electronically controlled geared motor unlocks or locks the door automatically. The technology is protected inside the door fitting. These locks are actuated by different control elements, such as timer, Infrared remote control, keypad or magnetic card systems.

The disadvantage here is that in two-leaf doors, the motor locking when unlocked by the lock in the passive leaf can not be unlocked with because the bolt of a motorized lock could not pass through the mating box of the castle in the passive leaf can be pushed back. Thus, you can conventional locks for double-leaf doors in escape and rescue routes not be equipped with a motorized lock.

The invention is based on the object, a simple design, cost, automatic unlocking and locking for double-leaf doors in escape and Escape routes through which a manual and an automatic opening and closing the doors is possible.

The object is solved by the features of claim 1.

The subclaims form advantageous embodiments of the invention.

A double-leaf door in escape and rescue routes for exterior building doors must be closed burglary resistant. For this it is necessary that not only the case engages in a arranged on the inactive leaf strike plate, but also the bolt, which requires that the door must be locked. There doors in escape and rescue routes from inside at any time with a handle openable must be, such doors are equipped with locks, which at Actuate the door interior fitting unlock the door, the trap and the Latch be pulled back into the lock and thus the passage through the Allow door opening. Particularly effective is an automatic locking, which the active leaf and the passive leaf, after this again in Closed, locked again.

For double-leaf doors, the locking of the inactive leaf can be combined with the active leaf, whereby only one lock is required. The castle can be arranged on the active leaf, the trap and the latch in the Engage the inactive leaf. Pushing the latch and latch back into the lock the active leaf through the castle in the passive wing would be omitted. The castle can also be designed as a multi-point lock, with additional bolts are formed in the upper and lower wing area and engage in the passive leaf.

To prevent the two-leaf door from being pushed open, the lock can be additional Have Treibriegel which up in the door frame or lintel and intervene in the floor below.

The locking of the double-leaf door with only one lock also requires that only a motor drive is required for the lock, whereby the parts and Installation costs and the cost of control elements and wiring reduced become.

Usually, such doors with door closers, which have a Closing control interact, brought into closed position. Will one used motorized locking, with both wings unlocked at the same time the wings can be equipped with revolving door drives, which Do not just lead doors into the closed position, but in case of danger open and hold open. It is also possible that the swing door drives, after the Alarm was reset, the doors close automatically again, and this be locked by a motor-driven lock.

For this purpose, a door control drive the lock and the swing door drive, wherein the door control is connected to a hazard alarm system or even can be triggered manually, for example by security guards.

In the following, an embodiment in the drawing with reference to FIGS explained in more detail.
