The discs are movable in relation to each other, wherein an additional braking action ensues by the friction of the discs upon each other.

Description

The invention relates to a device for closing sequence control for double-leaf hinged doors according to the preamble of claim 1.

From the DE 36 04 091 A1 Known as the closest prior art, a closing sequence control is known in which a arranged in the slide, provided with a locking member clamping plate is located on a longitudinally displaceable clamping rod. The inclined arrangement of the locking member on the clamping bar locks the active leaf with open wing, but allows further opening. In the closed position of the inactive leaf, the glider located on the swivel arm of the door leaf-side door closer triggers the blocking element via a transmission block and a push rod and makes it possible to close the active leaf. When the inactive leaf is open and an overload on the active leaf allows a stop member to trigger the locking member against an overload spring.

With this arrangement, with large sash weights, the clamping action of the clamping plate may not be sufficient, or it will notch the clamping plate in the locking bar and jammed.

The invention has for its object to form a locking device for a closing sequence control, which is suitable for large sash weights.

The object is solved by the features of claim 1.

The subclaims form advantageous embodiments of the invention.

The invention relates to a closing sequence control for a two-leaf, consisting of a moving leaf and a passive leaf door with overhead door drives. In or on the upper door frame slide rails are arranged, in which engage the door drives each with sliding arms arranged on sliders. The door drives can be integrated in the door wings or arranged resting on the door leaves. In the overlying arrangement of the door drives there is the possibility of mounting on the hinge side, ie the side of the doors on which the door is pivotally received in the door hinges or door hinges, or mounting on the corresponding opposite side, the hinge opposite side. The device according to the invention is designed so that a closing sequence control for all these types of installation with the same elements can be constructed. The stand-wing side and the gangway side slide are identical. In the slide rails designed as an extruded profile, the elements required for constructing a closing sequence device can be arranged.

For the construction of the closing sequence device, a trigger is arranged in the stanchion-side slide, which interacts with the side-wing-side slider such that when closed or at least approximately closed inactive leaf a lock which can be arranged in the gangway side slide releases the moving leaf. This ensures that the undercutting passive leaf is closed in front of the overflowing active leaf in the correct closing sequence. For this purpose, a transmission element is arranged between the trigger and the lock, which is advantageously designed as a cable, and space-saving in the slide and for bridging the area between the slides can be arranged. By using a cable, it is possible in the area between the slide rails to arrange additional components, such as a smoke detector or a motion detector. If none of these components are used, the gap can also be covered with a screen. Advantageously can be integrated in the wings door closers with the cable also locking elements of the door, which engage in the upper door frame, are bypassed.

The smoke detector can issue an alarm to a fire alarm control panel and trigger the door leaf, possibly detected by a locking device, so that it will be guided into its closed position by the door operators. It can also be integrated a motion sensor that controls the use of electric motor or electro-hydraulic door drives automatic opening and closing of the door.

The gangway-side lock has a clamping device which acts on a displaceable in the lock bar. On the locking bar, a release device is set, in which the gangway-side slider is first taken latching with the active leaf closed.

If the active leaf is opened, the slider is moved, whereby the release device and the lock bar are moved with. The compensation of the opposite movement of the slider at the beginning of the opening movement of the active leaf is made possible by the displaceable locking rod. There is no need for a spring element which displaces the locking rod, since the displacement is effected by the slider latched in the release device. A spring would take up additional installation space and affect the torque curve of the door drive, which is thus advantageously avoided.

After a predetermined displacement of the locking bar during opening of the active leaf of the slider is released by a arranged on the release device locking element is raised with a run-on slope arranged on this by a fixed fixed in the slide rail driver.

The height of the slider can advantageously be very low, so that further arranged in the slide elements, such as a locking device or serving to limit the opening buffer can be driven under, whereby large door opening widths - even beyond the locking device - possible are. This also applies correspondingly to the side-wing-side slider, which can interact with a locking device arranged in the side-wing-side slide rail.

By loosening the passer-side slider of the locking bar, it is possible to use a very short locking bar, so that even with narrow doors additional components between the slides can be arranged. If no additional components are used, the door width can be further reduced so that the slide rails connect directly to each other and the lock and the shutter are arranged immediately adjacent.

In order to ensure a safe locking of the active leaf with open wing even with large sash weights, a consisting of at least two slats, pivotable clamping element is arranged in the lock, which surrounds the locking bar, and - in the blocking direction of the active leaf - by the locking bar self-locking in the locked position is pivoted. Supporting a clamping spring is arranged, which acts on the clamping element in the reverse direction, so that it is pivoted by friction on the locking bar.

A further performance improvement of the barrier of up to 30% can be done by an additional braking device. For this purpose, a ramp is arranged in the release device for the gangway side slider, which partially adjusts the closing force of the door drive in the locking direction, which is applied against the overload spring arranged in the lock, depending on the angle of the ramp so that the release device against the upper inner wall of the slide braking is pressed. The release device and the slide can be provided with friction linings, consist of suitable friction material, or have a surface treatment, such as a coating or coating.

The release of the held in a partially open position active leaf takes place when closing the passive leaf by the shutter. For this purpose, a release plunger is arranged in the lock, which is actuated via the transmission element against a return spring and the clamping disk when the inactive leaf is closed pivoted into a position releasing the clamping, whereby the correct closing sequence of the door is ensured.

In order to prevent damage to the closing sequence control by overload, such as by manual closing of the detected active leaf, the clamping element is arranged in a displaceable against the overload spring clamping cage, whereby the clamping element is released in case of overload by the release plunger. The release also eliminates the counterforce on the release element, whereby the braking effect of the release device is released.

Advantageously, the holding force of the lock is adjustable by the trigger plunger is adjustable by an adjusting screw in position relative to the clamping element. The holding force results from the spring force of the overload spring and the braking force of the release device. The release of the lock by the trigger at a certain door opening angle of the inactive leaf is independent of the setting of the holding force, whereby malfunction of the closing sequence control can be avoided by an early release of the active leaf.

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

An embodiment of the closing sequence control with overhead door drives 3, 4 for the wings of a living leaf 1 and a passive leaf 2 double-leaf door, is in the Fig. 1 shown, wherein the door drives 3, 4 are arranged on the hinge side of the door leaf 1, 2, ie on the side of the door, on which also the door hinges are 20, in which the door wings 1, 2 are pivotally mounted. However, it is also possible any other arrangement, such as on the tape opposite side, or an integrated in the door wings 1, 2 arrangement.

The door drives 3, 4 arranged on the door wings 1, 2 each have a non-rotatably connected thereto sliding arm 5, 6 for power transmission. Sliders 7, 8 are rotatably arranged on the slide arms 5, 6 at the ends facing away from the door drive 3, 4, said slides being guided on the door frame 19 in slide rails 9, 10.

In the slide rails 9, 10, the elements for closing sequence control, such as lock 11, trigger 12 and transmission element 17 are arranged. Furthermore, the elements for detecting the door leaf 1, 2 in an open position by the locking devices 15, 16, with the associated power supplies 18 to the power supply, which are required if on site no extra voltage is available. In this case, only one power supply 18 for supplying both locking devices 15, 16 may be required. In addition, additional components for door control, such as smoke detector 13 or motion sensor 14 between the slide rails 9, 10 may be arranged. The entire assembly may be provided visually appealing with a cover.

For closing sequence control of the generic two-leaf door engages the passer-side door drive 3 with its arranged on the sliding arm 5 slider 7 in a guide groove arranged at the top of the door frame 19 gangway side slide 9 a. Correspondingly, the door-side door drive 4 engages with its slider 8 arranged on the sliding arm 6 in a guide groove of the slide-side slide rail 10.

In the slide rail 9, a lock 11 is provided for controlling the closing sequence at the poppet side, and a shutter 12 is arranged in the slide rail 10 at the door leaf side. In this case, the lock 11 prevents closing of the active leaf 1 when the inactive leaf 2 is open. The inactive leaf 2 acts on the trigger 12, which cooperates with the lock 11 via a transmission element 17, for example a cable pull. When the passive leaf 2 is closed by the shutter 12 and the transmission element 17, the lock 11 is triggered, whereby the active leaf 1 is guided by the door drive 3 in the closed position. This ensures that the undercutting passive leaf 2 is closed in front of the overflowing active leaf 1 in the correct closing sequence.

By using a flexible and relatively small diameter cable as transmission element 17, it is possible to use the area between the slide rails 9, 10 for the installation of the additional components. In this case, the smoke detector 13 can give an alarm to a fire alarm panel and possibly triggered by the locking device 15, 16 door 1, 2 trigger so that they are guided by the door drives 3, 4 in their closed position. Advantageously, a motion sensor 14 can be integrated, which controls the automatic opening of the door 1, 2 in the use of electric motor or electro-hydraulic door drives 1, 2.

The Fig. 2 shows the lock 11 with the active leaf closed 1, wherein the sliding arm 5 of the gangway side door drive 3 pivotally mounted slider 7 is received in a release device 21 of the lock 11.

The lock 11 has a clamping element 25 which cooperates with the trigger 12, and a displaceable along the longitudinal axis of the slide rail 9 locking bar 22 which in the direction of movement in the Fig. 2 is locked to the left or released. On the locking bar 22, the release device 21 is fixed, which has a latching element 23 which engages by its weight in the movement path of the slider 7.

If the active leaf 1 is opened, the slider 7 is displaced by the pivoting movement of the sliding arm 5 in the direction of the gangway side door hinge 20, wherein the release device 21 and the locking rod 22 are moved with. The compensation of the opposite movement of the slider 7 at the beginning of the opening movement of the active leaf 1 is possible by the freely movable locking bar 22 or - with simultaneous opening of the leaf 1 and inactive leaf 2 - a displacement of the locking bar 22 against an overload spring 28. The locking bar 22 does not require the opening or closing movement supporting Spring element, which claim additional installation space and would affect the torque curve of the door drive 3 with.

On the locking element 23, a ramp is arranged, which cooperates with a fixedly arranged in the slide rail 9 driver, which lifts the locking element 23 after a certain displacement movement and releases the slider 7 for a further door opening movement. It is possible that the locking bar is slightly bent or that the release device is vertically movable. Advantageously, the overall height of the slider 7 can be very low, whereby this further, arranged in the region of the slide rail 9 elements, such as the locking device 15, can move under. This also applies accordingly to the side-wing-side slider 8, which cooperates with the locking device 16. As a result, larger door opening widths - regardless of the, by the positioning of the locking device 15, 16 certain locking angle - possible.

By the release of the slider 7 by the release device 21, it is possible to use a very short locking bar 22, whereby the space between the lock 11 and the trigger 12 for the installation of other elements, such as smoke detectors 13 or motion sensor 14 is available. It can be realized with very narrow door wings 1, 2 double-leaf doors, since the lock 11 and the trigger 12 are directly adjacent can be arranged.

If the inactive leaf 1 is now opened when the active leaf 1 is open, the trigger 12 causes the barrier 11 to move the blocking rod 22 in the direction of movement Fig. 2 locks to the left. For this purpose, the lock 11 on a clamping cage 24, in which a pivotally locking bar 22 encompassing clamping element 25 is arranged, which is acted upon by a clamping spring 32 in the direction of its clamping position.

The clamping element 25 consists of a package of several slats 26 in order to achieve a secure clamping of the locking bar 22, whereby a safe locking of the active leaf 1 is possible at high sash weights. Due to the spring load by the clamping spring 32, the clamping element 25 in a Position obliquely guided to the direction of displacement of the locking bar 22, whereby this tilted in the clamping element 25, and the locking bar 22 is clamped. Further displacement of the locking bar 22 is prevented.

If the active leaf 1 moves in the direction of its closed position, the slider 7 comes into contact with the release device 21, which is supported on the locked blocking rod 22. The slider 7 locked in the release device 21 by lifting the locking element 23 on a ramp and underfoot. After complete underrun, the locking element 23 falls behind the slider 7 back into the path of movement of the slider 7 back. The slider 7 is in its locked in the release device 21 position.

Since the lock 11 is in its locked position, the slider 7 comes into abutment with a bevel 31. The release device 21 and the locking rod 22 are against the force of the overload spring 28 - Fig. 2 to the left - moved. Due to the slope 31, depending on the angle of the bevel 31, a part of the counterforce to the spring force on the release device 21 in the direction of the inner wall of the slide rail 9 - Fig. 2 upwards - steered. The result is an additional braking force by the release device 21, which may be provided in its cooperating with the slide rail 9 area with a friction lining or may be made of a suitable material. Also possible is a surface treatment or a coating that influences the braking behavior. The slide rail 9 can be designed accordingly. This brake unit supports the braking action of the overload spring 28, whereby higher forces can be absorbed.

By the locked locking bar 22 of the active leaf 1 is now held in a partially open position, which allows closing of the inactive leaf 2 in front of the active leaf 1. If the inactive leaf 2 is closed, the trigger 12 releases the clamping of the blocking rod 22, as a result of which the blocking rod 13 continues to move Fig. 2 to the left - to shift. The active leaf 1 closes in the correct closing sequence after the passive leaf. 2

To release the lock 11, this has a receptacle 27 in which a acted upon by a return spring 30 release plunger 29 is guided, which is actuated by the transmission element 17 from the stand-wing-side trigger 12 to release the lock 11. To trigger the lock 11, the release plunger 29 pivots the locking bar 22 encompassing clamping element 25 so that the locking bar 22 is freely displaceable by the clamping element 25. As a result, the overload spring 28 can relax, whereby the force effect on the release device 21 is eliminated, and thus there is no more braking action. The holding force of the lock 11 is adjustable by the trigger plunger 29 is adjusted by the adjusting screw 33 in position relative to the clamping element 25. The holding force results from the spring force of the overload spring 28 and the braking force generated by the release device 21. According to the setting of the trigger plunger 29, the clamping element 25 comes into contact with this, whereby the clamping element 25 is pivoted in the direction of its locking bar 22 releasing position. The release of the lock 11 by the trigger 12 is independent of the adjustment of the holding force, whereby the door opening angle of the passive leaf 2, in which the trigger 12 releases the lock 11 is not changed, and thus malfunction of the closing sequence control by an early release of the active leaf 1 be avoided.

If the active leaf 1 further opened, the locking rod 22 can be moved through the clamping member 25 through, since the pivotally mounted against the clamping spring 32 in the clamping cage 24 clamping member 25 pivots in the direction of the locking rod 22 releasing position. If the locking rod 22 is moved further with the release device 21 in the opening direction of the active leaf 1, the release device 21 triggers the slider 7 again.

If an overload on the lock 11, for example, when trying to close the locked leaf 1 by hand, the clamping cage 24 is moved against the overload spring 28. In the end region of the possible spring travel of the overload spring 28, the release plunger 29 lifts the blocking of the blocking rod 22 by the clamping element 25.

The clamping element 25 is formed from a series of at least two slats 26. Due to the friction of the slats 26 when pivoting each other, during the braking process, there is an additional energy reduction of the movement of the active leaf 1, whereby the holding force of the lock 11 is further increased. Due to the interaction of several hardened blades 26 with the hardened locking rod 22, the blades 26 are automatically pivoted in a movement of the locking rod 22 in the locking direction, in the clamping position, with self-locking and low wear by a plurality of clamping points corresponding to the number of slats 26th results.

Since the fins 26 need only a hole as a recess for the locking bar 22, and have a small thickness, an inexpensive production is possible as a fine blank. Advantageously, the hardened locking rod 22 can be produced inexpensively, since a short rod has a low hardness distortion, which causes no disturbing effects on the short displacement of the locking rod 22 until the release of the slider 7, this hardening distortion.
