Description

The invention relates to a two-leaf revolving door according to the preamble of claim 1.

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

In this arrangement, it is disadvantageous that an automatic locking and unlocking is not possible. Thus it is not possible to use an automatic door drive. The door can therefore in particular escape and escape routes therefore not automatically release an escape route and automatically close again after an alarm and then lock burglar-resistant.

The DE 44 38 210 A1 shows a revolving door with a moving leaf and arranged on the active leaf lock, in particular multi-bolt lock, with a third-party drive, such as a mechanical or electrical drive for the bolt or the push rods, with a gear that assigned to operate the bolt or the push rods this is, with a power storage in conjunction with the third-party drive and with a lock cylinder, wherein the force accumulator has a coil spring between a wheel or gear rim and a hub and is turned on in the lock housing in the kinematic connection between the external drive and the transmission.

The EP 02 88 454 A2 shows a locking device for a two-leaf door, with a fixing device for locking one of the two leaves relative to the door frame and a lever-operated latch lock for mutual locking of both leaves, wherein the fixing device and the latch lock are arranged on the same door, and the fixing of a in the The upper edge of the door edge is fitted with edge catch, which is activated simultaneously with the latch of the latch lock lever Fallenschlosses against a spring force from the closed position is retractable into an open position.

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

Also known are latches for double-leaf revolving doors, the active leaf a Einfallenschloss and the inactive leaf has a bolt lock and the wings are guided by door closers in their closed position. A floating bolt lock has vertical bars which lock the wing in the floor and in the upper door frame, the bars there engaging in corresponding recesses or bores. The door closers have a closing sequence control, whereby a closing of the active leaf takes place only after closing the inactive leaf and thus the wings are closed in the correct order.

To secure building exterior doors in escape and rescue routes, a burglar-proof locking is required. For this purpose, it is necessary that the latch engages in the strike plate and keeps the door closed.

An escape in the direction of escape must be done in accordance with the regulations at any time by a handle. Therefore, so-called panic locks are used, which simultaneously retract the lock latch and the bolt from the inside when the handle is actuated. When the handle is operated from the outside, the door remains locked because the outer fitting is not connected to the lock mechanism.

When committing to the active leaf in the direction of escape, the trap and the bolt is pushed back and the active leaf can be opened, with the inactive leaf remains closed over the drive bolt lock. The escape route is so far only partially released. If the fitting of the inactive 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, with an electronically controlled geared motor automatically unlocking or locking the door. 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.

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

The invention has for its object to form a two-leaf revolving door in escape and rescue routes, which has a simple design, cost-effective, automatic unlocking and locking, by a manual and automatic opening and closing of 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 burglar-resistant. For this it is necessary that not only the trap engages in a arranged on the fixed leaf strike plate, but also the bolt, which requires that the door must be closed. Since doors in escape and rescue routes must be openable from the inside at any time with a handle, such doors are equipped with locks, which unlock the door upon actuation of the door interior fitting, the trap and the latch are withdrawn into the castle and thus the passage through the Allow door opening. Particularly effective is an automatic locking, which locks the active leaf and the inactive leaf, after they are again in the closed position, again.

The locking of the passive leaf of the double-leaf door takes place together with the active leaf, whereby only one lock is required. The lock is arranged on the active leaf, wherein the latch and the latch engage in the passive leaf. Pushing back the latch and latch in the lock of the active wing through the castle in the grand piano would be omitted. The lock may also be designed as a multi-point lock, wherein additional bolts are formed in the upper and lower wing area and engage in the passive leaf.

In order to prevent the two-leaf door from being pressed on, the lock can have additional drive latches which engage in the top of the door frame or lintel and at the bottom of the floor.

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

Such doors are brought into closed position with door closers or revolving door drives, which interact via a closing sequence control. Using a motorized lock, both wings being unlocked at the same time, the wings are equipped with revolving door operators, which use the Do not just open doors to the closed position, but open them in case of danger and keep them open. It is also possible that after the alarm has been reset, the revolving door drives automatically close the doors again, and these are locked by a motorized lock.

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

In the following an embodiment in the drawing with reference to the figures will be explained in more detail.

Figures 1 to 3 show a lock 3 for a double-leaf door in escape and rescue routes, with a passive leaf 1 and a leaf 2, wherein the active leaf 2 has a lock 3 with at least one latch 10, wherein the inactive leaf 1 through the lock third the active leaf 2 is locked and the inactive leaf 1 has no own lock 3.

The inactive leaf 1 and the active leaf 2 can be guided into their closed position by an electric revolving door drive 6 or by door closers. In this case, a closing sequence control control the closing of the inactive leaf 1 in front of the active leaf 2 such that the wings 1, 2 close in the correct sequence, whereby the case 9 of the lock 3 can engage in the striking plate 11 of the passive leaf 1.

The closed position of the wings 1, 2 can be detected by the position of the revolving door drive, or it can be attached to the door frame, a sensor which detects the closed position of the wings. This sensor may, for example, be a reed contact, it being possible for a magnet to be attached to the active leaf, which magnet interacts with the reed contact.

Are the wings 1, 2 in the closed position, the door can be locked by the lock 3 by the bolt 10 is brought into operation by pressing the lock cylinder 12 with a key or by a motor drive 4 in the lock 3 with the strike plate 11. By the engagement of the bolt 10 in the strike plate 11 of the passive leaf 1 and by the intervention of the Treibriegelstangen 5 in the floor and the upper door frame, the door is securely locked. Also, a pressing of the wings 1, 2 is not possible, since the locking of the passive leaf 1 by the locking of the active leaf 2, wherein only one lock 3 is required.

To commit the closed and locked door in the direction of escape can be unlocked by pressing the handle on the fitting 7, the door. In this case, the latch 10 is withdrawn from engagement in the strike plate 11 of the passive leaf 1 in the lock 3. At the same time the Treibriegelgestänge 5 is withdrawn from engagement with the stationary door environment, such as floor and upper door frame or lintel. As a result, the active leaf 2 and the passive leaf 1 is free and can be opened, whereby the escape route is available in its entire width.

The provided with a swing door drive 6 and a closing sequence control wings 1, 2 are returned to their closed position. By a sensor, such as a reed contact, the closed position is detected, and by the arranged in the lock 3 drive 4 is the Treibriegelgestänge 5 with the stationary door environment and the latch 10 with the strike plate of Fixed wing 1 locked and closed the building again burglar resistant.

In the event of an alarm, the door communicating with a fire alarm device is automatically unlocked by the drive 4 arranged in the lock 3, the bolt 10 being retracted into the lock 3 and the locking bolt linkage 5 being withdrawn from the stationary door environment. By the revolving door drive 6, the wings 1, 2 are guided in their open position, whereby the escape route is released and a smoke outlet is made possible. The door can also be returned to its closed position by the revolving door drive 6 if, for example, the alarm of the fire alarm device is acknowledged. The wings 1, 2 are guided by the revolving door drive 6 in the correct order in its closed position, wherein the position of the wings 1, 2 z. B. can be detected by sensors. This can be, for example, a reed contact or a rotary encoder in the revolving door drive 6. By arranged in the lock 3 drive 4, the drive bar linkage 5 are locked with the stationary door environment and the bolt 10 with the strike plate of the inactive leaf 1 and the building is secured again.
