Abstract

Normally fixed leaf of a double door has a clamp lock (9) operated by a connecting rod (7) which is retained when the door is opened and released when it is closed. A lock (6) in or on the other door, which is normally opened for passing through, has a control cam slider slides in the lock bolt (11) and has a control pin (22) which projects beyond the lock bolt so that when the fixed door lock is operated, the control slider lifts the slider (24) locking the lock bolt via a plunger and lug. Preferably a gear wheel (14) is positioned between two connecting rod sliders (12,13) of the fixed door lock and is coupled to a latch bolt ejector (15).

Description

The invention relates to an unlocking and locking for a passive leaf and a door with active leaf, the passive leaf being connected by means of a Driving bolt lock opposite the door frame or the like and the Active leaf with a key-operated lock opposite the Inactive leaf can be fixed and in or on the inactive leaf a dead bolt lock arranged with two counter-driving rods is what means for closing a lock latch and a lock bolt of a lock arranged in or on the active leaf. At Such doors, which are usually folded, it is customary that when opening the door, first the active leaf and then the Inactive leaf opened and when the door was closed, the inactive leaf and then the active leaf is closed. When closing the The door therefore has a fixed wing compared to the active wing Advance in time, but it must be ensured that both door leaves be reliably locked.

A generic device is known from DE 29 14 372 C2. In the known device the actuating rods are actuated assigned lock nut a forced pivoting of at one Driving rod arranged release levers, which both the lock latch as well as the lock bolt of a latch-slide bolt panic lock. To do this, the slide bolt interacts with a switch bolt, via its actuation, the locking position of the slide bolt in its pre-closed position Position is lifted so that the passive wing and the The active leaf can be opened by actuating the drive bolt lock can. When closing the door it is necessary to both the connecting rods of the passive leaf and the active leaf opposite the passive leaf lock manually. It is therefore necessary to operate the door twice, i.e. Inactive leaf and active leaf must each be separated be locked.

From DE 29 14 377 C2 a drive bolt lock is also known, which has a locking bracket provided with a latch insert member, wherein the latch insert member retracts the lock latch when the drive bolt lock the inactive leaf is unlocked, i.e. the drive bar rods retracted become. It is formed by means of a component of the locking bracket Bolt locking cam blocks the actuation of the drive bolt lock, i.e. the passive leaf cannot be opened as long as the lock bolt the active leaf is not closed. For opening and closing of the active leaf is therefore always the actuation of the latchbolt lock required in the active leaf; opening both wings by pressing the drive bolt lock is not possible.

DE 29 12 881 C2 and DE 31 42 959 C2 describe drive rod closures for door leaves where a blocking device for the Driving rods of the driving bolt lock are used. The blocking device is suitable, on the one hand, the connecting rods when opening the To hold the passive leaf in its retracted position and on the other hand the Release connecting rods when closing the passive leaf, so that they when closing the passive leaf automatically spring-loaded in corresponding Can snap recesses in a door frame or the like.

The object of the invention is to unlock and lock both door leaves as simple as possible; in particular, it should be achieved that the Unlocking both door leaves as well as locking both door leaves with a single manual operation.

The invention solves this problem by teaching according to claim 1.

By means of a drive bolt lock arranged in the passive leaf, at closed door leaves of the passive leaf are unlocked manually, whereby the drive rods of the drive bolt lock in the retracted position automatically held in its retracted position by the clamp lock become. At the same time are arranged in the dead bolt lock Middle both the lock latch and the lock bolt of the in the active leaf arranged lock closed, so that the until then The active leaf, which is locked in relation to the passive leaf, is also open at the same time can be.

To open the two-leaf door, it is therefore only necessary that To operate the dead bolt lock manually using a handle.

Since according to claim 1, the clamp lock the drive rod of the Active leaf lock arranged only when the active leaf is open locked and released with the inactive leaf closed, this results in that when closing the passive leaf the drive rods of the drive bolt lock extend automatically and so opposite the passive leaf lock the door frame (a door frame or the like). This means that the passive leaf automatically locks itself by accident; the subsequent Locking between active leaf and passive leaf can be done by Actuation of the key-operated lock arranged in the active leaf respectively.

The result is only a single manual actuation of the drive bolt lock in the passive leaf to open and only one manual operation the lock in the active leaf to close the double-leaf door required.

Further features of the invention are characterized by the subclaims.

According to claim 2, the drive bolt lock has two drive rod connecting slides on which counter-rotating through a common gear are drivable, the between the two connecting rod connecting slides arranged gear has a double function in so far when it is geared to a lock latch ejector.

With respect to the two, arranged in the drive bolt lock and in opposite directions drivable connecting rod connecting slide is according to claim 3 one via its associated drive rod with the clamp lock and the others with a lock bolt ejector arranged in the drive bolt lock coupled. This means that with the actuation of the preferably lever operated lock bolt not only the two the connecting rod slide arranged drive rods retracted or extended be, but that when retracting the drive rods also at the same time a lock latch ejector and a lock bolt ejector are actuated, which the lock latch or the lock bolt arranged in the active leaf Close the lock. The lock arranged in the active leaf is preferred designed as a tubular frame lock.

In a further embodiment of the invention, the with the lock bolt ejector coupled connecting rod connecting slide a guide slot and the lock bolt ejector one with the guide slot of the Espagnolette connecting slide corresponding pin. This one in Espagnolette connecting slide arranged guide slot runs in at Lock slide known manner approximately diagonally to the direction of displacement the drive rods so that when the drive rod connecting slide is actuated the lock bolt ejector towards the lock bolt of the im Active leaf arranged lock is moved (claim 4).

In a further advantageous embodiment of the invention there is the lock bolt ejector of two variable in the direction of the lock bolt Share (claim 5). With the help of changing the distance between the two Parts of the lock bolt ejector can be adjusted to between Inactive leaf and active leaf are inevitably different Door air.

With regard to the formation of the clamp lock takes place to repeal the clamping effect use a trigger role, the glide path according to Claim 6 is adjustable via an adjusting screw.

The trigger roll undermines any when closing the passive leaf designed counter bearing, preferably a counter wedge, so that the pressure exerted on the release roller the clamping between the Drive rod and a clamping plate picks up and the drive rod in one Hold the corresponding counter bearing of the door frame, the door frame or the like can.

According to Figure 1, the door 1 consists of a leaf 2 and a Active leaf 3, which are mounted in a door frame 4. In leaf 2 is a drive bolt lock 5 is arranged, which is an upper one, with a clamp lock 9 interacting drive rod 7 and a lower drive rod 8 having. The arranged in the active leaf 3, key-operated lock 6 designed as a tubular frame lock.

In FIG. 2, the one that interacts with the clamping lock 9 is on the left in the image plane Driving bolt lock 5 shown. The driving bolt lock 5 has two drive rod connecting slides which interact with the drive rods 7 and 8, respectively 12 or 13. Between the upper one in the image plane Espagnolette connecting slide 12 or its connecting rod 7 and the A compression spring 33 is arranged in the housing 32 of the drive bolt lock 5, which is supported in its operation by an additional tension spring 44 becomes. With 14 that between the connecting rod connecting slides 12, 13 is arranged Gear wheel, which is the opposite movement of the Espagnolette connecting slide 12, 13 causes.

In the image plane on the right is that which interacts with the driving bolt lock 5, shown key-operated lock 6, which in known Has a slide 24 and a lock bolt 11.

The unlocking and locking device works as follows:

Starting from the closed position shown in Figure 2 the door is a follower 34 by means of an associated, not shown Lever operated in the left-turning sense, so that the connecting rod connecting slide 12, 13 are moved in opposite directions. This is done via lifting the connecting rod connecting slide 13 by means of a panic lever 35. The rotating gear 14 moves both the Espagnolette connecting slide 12 with the associated espagnolette 7 in the image plane down as well as a lock latch ejector 15 in the Image plane to the right against a lock latch 10.

At the same time, the one arranged on a lock bolt ejector 16 slides Pins in a guide slot 17 of the connecting rod connecting slide 13, so that the existing from the two variable parts 19, 20 Lock bolt ejector 16 moves to the right in the image plane and runs against a control pin 22 of a control slide 21. The Control slide 21 (see Figure 5) is slidably guided in the lock bolt 11 and moves due to the action of the lock bolt ejector 16 a plunger 36 (see FIG. 5) against a stop lug 25 on the slider 24 (see Figure 6) of the lock 6. A Lock bolt 11 arranged pin 37 from the in a slot 39 of Slider 24 arranged latch 38 released, so that the lock bolt ejector 16 press the lock bolt 11 back into the locked position can. The control slide 21 now runs flush with one End face 23 of the lock bolt 11.

For precise positioning between part 20 of the lock bolt ejector 16 and the control pin 22 of the control slide 21 ensure parts 19, 20 of the lock bolt ejector 16 can be distanced by screw connections 40 (see FIG. 3).

Both door leaves can now be opened.

In the open position, both the passive leaf 2 and the Active leaf 3 by suitable, conventional tools such as door locks or Like. Be determined.

When the door is closed, the passive leaf 2 is opened in the usual way closed with advance notice, which z. B. by a closing sequence controller can be done in conjunction with appropriate door closers. To the The locking lock 9 is used to automatically close the passive leaf 2. The clamp lock 9 consists essentially of a base body 41, a guide bracket 42, a rotary bearing 26 for a clamping plate 28, a compression spring 27, a trigger device (trigger roller) 29 and one Adjustment screw 30, the entire clamp lock 9 at one in the upper face of the active leaf 3 recessed faceplate 31 is attached.

In Figure 7, the drive rod 7 and the clamp lock 9 are in the open Position of the passive leaf 2 shown. It can be seen that the Clamping plate 28 is inclined relative to the drive rod 7 has and by the compression spring 27 in this inclined position in which it clamping the drive rod 7 is held. When closing the Inactive leaf 2 undermines the trigger roller 29 in or on a wedge or the like the frame of the door 1 and moves the guide pin 43 together the clamping plate 28 against the pressure of the compression spring 27 in the image plane down so that the clamping effect between the drive rod 7 and Clamping plate 28 is lifted and the drive bolt 7 in the image plane X through the faceplate 31 in a not shown, arranged in the frame Can enclose counter bearing.

The passive leaf 2 is thus automatically locked when it closes. At the same time is caused by the movement of the associated connecting rod connecting slide 12, 13 the lock latch ejector 15 and the lock bolt ejector 16 retracted into its position shown in Figure 2, so that the Locking between the driving bolt lock 5 and that in the active leaf 3rd Arranged lock 6 by closing the lock bolt 11 by means of Key actuation of the lock 6 can be done. For the closing process is therefore only a single manual operation, namely that of Lock 6 required.
