Description

The invention relates to a closing sequence control for door closers according to the preamble of claim 1.

From the EP 0 386 600 A1 a device for controlling the closing sequence of two closable by means of a respective door closer wing of windows or doors is known. The drive axle of the gangway-side door closer carries a locking cam, which forms a locking device for the partially opened, the correct closing sequence enabling active leaf, and which is connected via a tension member with a release lever, which with a connected to the drive axle of the door leaf-side door closer trigger levers with a spring-loaded locking lever Tripping device forms, which holds the locking lever approximately in the closed position of the inactive leaf against the resistance of a loading spring or springs in an ineffective position.

A disadvantage is the large number of components, which may be impaired by tolerances, wear and length changes the reliability. The determination of the active leaf takes place against a stop, which in particular in a large, heavy door high energy must be removed, which could lead to damage.

The invention has for its object to provide a safe and reliable closing sequence control for door drives.

The object is solved by the features of claim 1.

The subclaims form advantageous embodiments of the invention.

A closing sequence control device ensures that, on a double-leaf door equipped with door leaves and having a moving leaf and a passive leaf, the falling passive leaf logically closes in front of the swinging active leaf. For this purpose, the active leaf is held by a locking device in a partially open position with the inactive leaf open, wherein the locking device cooperates with an actuatable by the inactive leaf triggering device.

The arranged in the floor below the door leaf drives are rotatably connected with their output shafts each with the associated wing of the door. The barrier is in this case the gangway-side door drive and the triggering device on the door leaf-side door drive arranged as a retrofit module, wherein between the triggering device and the locking device, a transmission element is provided, whereby the triggering device cooperates with the locking device.

The triggering device arranged around the output shaft of the door leaf-side door drive detects the door opening angle of the passive leaf as a function of the rotational position of the output shaft. Near the closed position of the inactive leaf, d. H. if this is closed so far that the provided with a projecting fold active leaf certainly can not close in front of the inactive leaf, a trigger slide is actuated by a driver. As a result, the rotational movement of the output shaft is converted into a linear movement, which is transmitted to a transmission element, such as a rod or a Bowden cable, arranged on the gangway side door drive locking device.

Between the triggering device and the locking device, a device is provided which causes a variable transmission ratio of the triggering stroke movement of the transmission element, so that the distance required for the locking device and the required force are available in the respective operating phase. Advantageously, both manufacturing tolerances, wear and a possible change in length of the transmission element can be compensated by this device.

The proposed locking device has a lock which allows detection of the active leaf at any door opening angles by several preferably designed as rollers locking body the gangflügelseige output shaft directly or indirectly via a rotatably mounted on the output shaft bearing arranged against arranged in a bearing ring of the lock, the respective locking body clamp assigned contour. This does not require the high forces of a moving wing to be absorbed. Advantageously, the locking bodies are released by a toothed switching ring, which is operatively operated by a release slide with the triggering device, wherein each locking element is associated with a tooth.

Furthermore, an overload protection is provided which prevents damage to the active leaf or the locking device, if an improper, manual closing of the detected active leaf takes place. In this case, the lock with the locking body bearing bearing ring rotates against the switching ring, causing a release of the lock is effected. Advantageously, no additional release elements in the lock are required for the overload release, since a kinematic reversal of the effect of the switching ring with respect to the im Bearing ring arranged locking body is provided at a release by the triggering device of the passive leaf or overload.

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

In the 1 a double-winged door is shown, with a sweeping moving leaf 1 and a knockout wing 2 , It is every wing 1 . 2 a door drive 3 . 4 assigned. The below the active wing 1 arranged in the floor wing-side door drive 3 is with its output shaft 5 with the active leaf 1 rotatably connected. Accordingly, the below the passive leaf 2 in the floor arranged stand-wing-side door drive 4 with its output shaft 6 with the passive leaf 2 rotatably connected. The door drives embedded in the floor 3 . 4 are each covered with a bottom cover plate on the floor. Between the door drives 3 . 4 is a transmission element 7 arranged, which is part of the closing sequence control described below, which is a logical closing of the inactive leaf 2 in front of the active wing 1 causes.

In the 2 are the door drives 3 . 4 with the output shafts 5 . 6 isolated shown in a plan view. In addition to that between the door drives 3 . 4 arranged transmission element 7 are still control lines 8th . 9 shown on the provided with a locking device drives 3 . 4 an example electromagnetic locking device is controllable, which allows the wings 1 . 2 to keep the door in an open position. This is often done by the operation of a hydraulic valve in the door drive 3 . 4 ,

In the 3 are the door drives 3 . 4 shown without bottom covers, so that the elements of the closing sequence control can be seen. To control the closing sequence is on the rocker side a triggering device 10 and gangway side a locking device 11 arranged, each as a module on the associated drive 3 . 4 attachable. This prevents the locking device 11 a closing of the active wing 1 when the inactive leaf 2 is in an at least partially open position. The triggering device 10 and the locking device 11 are as prefabricated, separate module on the respective door drive 3 . 4 established. In the figures are both triggering device 10 as well as the locking device 11 shown with removed housing. The transmission element 7 is length-related according to the mounting distance of the door drives 3 . 4 prefabricated or is matched during assembly to the required length.

The passive wing 2 acts via the triggering device 10 and the transmission element 7 , For example, a Bowden cable or a rod, on the locking device 11 one. With closed inactive leaf 2 triggers the triggering device 10 the locking device 11 , so that the active leaf 1 through the door drive 3 is guided in the closed position, whereby it is ensured that the underpowering passive leaf 2 in front of the overflowing active leaf 1 closed in the correct closing sequence.

The triggering device 10 has an axle 12 on, the rotation with the output shaft 6 is arranged around this. On the axle 12 is a driver 13 set that with a shutter slider 14 interacts with a hook 15 is formed, which on the axle 12 away in the range of motion of the driver 13 protrudes. When falling below a certain opening angle of the inactive leaf 2 takes the driver 13 the hook 15 of trip slider 14 against the force of a spring 16 with, whereby the transmission element 7 to release the locking device 11 is moved. The feather 16 is in a recess 17 of the shutter slide 14 arranged and supported against a leader 18 which is in the recess 17 for guiding the release slide 14 intervenes. In 3 is the driver 13 shown at the beginning of the release process, with the driver 13 just in contact with the hook 15 of the shutter slide 14 at a door opening angle of the inactive leaf 2 is, for example, 15 °, in which it is ensured that the sweeping active leaf 1 after the passive leaf 2 closes.

On an extension 19 of the shutter slide 14 is a clamping piece 20 determined at which the transmission element 7 , here a Bowden cable, with his wire rope 21 is clamped. The wire rope sheath 22 of the Bowden cable is in a receptacle 23 supported. Andernends is the transmission element 7 in the locking device 11 taken, with the wire rope sheath 22 also in a recording 23 is supported. The wire rope 21 is here in the wire rope tensioner 24 set which part of a drawbar 25 is.

Between the triggering device 10 and the locking device 11 a device is provided which has a variable transmission ratio of the triggering stroke movement of the transmission element 7 causes. This device is in the area of the barrier device 11 arranged.

The lifting movement of the transmission element 7 gets through the drawbar 25 on a rocker arm 26 transferred, which with a bearing axis 27 pivotally in the locking device 11 is stored. One on the rocker arm 26 fixed pin 28 engages in a backdrop 29 one which on a release slider 30 is omitted. The release slider 30 serves to release the lock 31 the locking device 11 , whereby the wing-side door drive 3 is released. The release slider 30 is also with a recess 17 provided and on a guide block 18 guided.

The lifting movement of the transmission element 7 is therefore initially in a rotational movement of the rocker arm 26 transformed and by the in the scenery 29 guided cones 28 again in a linear movement of the release slider 30 transfer. The one in the bearing axis 27 rotatably mounted rocker arms 26 with the in the backdrop 29 in the release slider 30 guided cones 28 allows a variable gear ratio during the release process of the locking device 11 , The contour of the backdrop 29 is curved in a curve and can be divided into three areas, which are designated as functional areas FB1 to FB3, as these in 4 are shown.

The functional area FB1 is a region of great gradient in the scenery 29 , whereby the rotational movement of the rocker arm 26 a relatively large stroke of the release slide 30 causes. In particular, this results in manufacturing tolerances, wear or length differences of the wire rope 21 , which can be caused by temperature fluctuations or elongation, or even in the lock 31 required movement play balanced, creating a safe operation of the lock 31 is guaranteed.

In the functional area FB2, the area of the transition in the apex of the curved contour of the backdrop 29 indicates, only a small stroke of the release slider is still done 30 However, a large force on the release slider 30 achieved. It is for the displacement of the release slider 30 only a small force on the transmission element 7 required, with a large force to release the lock 31 is given, so that a secure release of the lock is guaranteed.

The functional area FB3 indicates an area in which the curvature of the backdrop 29 a circular arc around the bearing axis 27 describes, causing a further displacement movement of the transmission element 7 no sliding movement of the release slider 30 causes. Through this idle stroke of the transmission element 7 can tolerances, wear in the entire transmission system or an elongation of the wire rope 21 be compensated.

In the 5 is the lock 31 the locking device 11 shown in the cutout, with a cover of the lock 31 is removed to the elements of the lock 31 to show.

The barrier 31 includes a lock housing 32 which is a recess 33 for the passage of the release slide 30 having. The lock housing 32 also takes the cover, not shown in the figures of the lock 31 on. Furthermore, a nose 34 on the circumference of the lock housing 32 arranged, which, as described below, part of a device for overpressing the locking device 11 is. An overpressure occurs by the manual operation of the detected active leaf 1 in the closing direction against the barrier 31 ,

In the lock housing 32 are furthermore a switching ring 35 and a bearing ring 36 taken in the 7 and 8th shown as a single item. The bearing ring 36 is in the lock housing 32 above the switching ring 35 arranged, whereby at the switching ring 35 arranged teeth 37 into the area inside the bearing ring 36 protrude into it, as it is in the 6 is shown. The switching ring 35 and the bearing ring 36 are in number and arrangement of Tuned coordinated parts, which are preferably arranged distributed uniformly on the circumference.

As it is in the 7 is shown is on the switching ring 35 a recording 38 present, in which the release slider 30 is pivotally fixed, for example by means of a bolt. The bearing ring 36 has at its periphery a plurality of each provided with a threaded holes 39 on, which in each case an assigned groove 43 end up. Between the neighboring grooves 43 is each a section with a contour 41 arranged. On the output shaft 5 is a warehouse 42 rotatably arranged, which within the barrier 31 is included.

In each of the grooves 43 in the bearing ring 36 is one with a spring 40 acted on plunger 44 arranged, which on a blocking body 45 acts. In the holes 39 each is a grub screw 46 arranged, which to adjust the force of the spring 40 on the pestle 44 and thus on the lock body 45 serves. As shown in the figures, each of the locking bodies lies 45 spring loaded on the outer circumference of the bearing 42 and at the assigned contour 41 of the bearing ring 36 at.

In the 5 is the lock 31 with the release slider 30 shown, wherein the bearing ring 36 in the area of the release slide 30 is recessed to its arrangement on the switching ring 35 to show. The recessed area is marked by dashed lines indicated by arrows A. In the 5 is the lock 31 activated and the active leaf 1 noted in a partially open position. In the 9 is this activated position of the lock 31 shown in the clipping. The locking bodies 45 are spring-loaded on the contour 41 and on the outer circumference of the bearing 42 at. The contour 41 is wedge-shaped, so that the distance between the contour 41 and the camp 42 towards the tooth 37 the Schalring 35 reduced. By the torque of the wing-side door drive 3 in the closing direction, the blocking body 45 in the clamping area of the contour 41 between the contour 41 and the camp 42 jammed, which rotatably on the output shaft 5 arranged bearings 42 against in the lock 31 rotationally fixed bearing ring is established. The barrier 31 herself is there with her nose 34 in a depression 47 an overload slide 48 supported as it is in the 3 is shown. The closing movement of the active leaf 1 is when the inactive leaf is open 2 stopped immediately, which does not cause the high kinetic energy of a moving active leaf 1 , which is determined by the wing mass and the speed of the wing, in the barrier 31 must be reduced. A movement of the active wing 1 in the opening direction is possible at any time, as in a rotational movement of the output shaft 5 clockwise the locking body 45 through the camp 42 in the direction of the extended area of the contour 41 be relocated.

The triggering of the lock 31 is achieved by closing the inactive leaf 2 initiated. Once the passive wing 2 falls below a certain door opening angle, by the triggering device 10 and the transmission element 7 the release slider 30 moved to the left and the switching ring 35 converted into a clockwise rotation. The teeth 37 the Schalring 35 first get into contact with the associated blocking bodies 45 and urge them on further turning in the direction of the spring-loaded plunger 44 in the extended area of the wedge surface of the contour 41 back, as it is in the 10 shown in the clipping. This is the clamping of the locking body 45 between the bearing ring 36 and the camp 42 lifted, causing the output shaft 5 the gangway-side door drive 3 free and the active wing 1 is led into its closed position.

As already mentioned above, the locking device comprises 11 an overload protection, which prevents it from improper manual closing of the through the open passive leaf 2 detected active wing 1 damage to the active wing 1 or the locking device 11 he follows. Starting from the in the 5 and 9 shown locked position of the bearing 42 and thus the gangway side door drive 3 , is in the 10 and 11 an overpressure of the lock 31 by manual operation of the active leaf 1 shown in the closing direction in the neck.

The overload slide 48 is in a leadership 49 guided and by an overload spring 50 applied. The behavior of the overload slide 48 is by means of an adjusting screw 51 adjustable. In the normal position is the nose 34 of the barrier housing 32 in the depression 47 the overload slide 48 added. Will now be the detected active leaf 1 manually operated in the closing direction, so is by the blocking between the rotationally fixed on the output shaft 5 the gangway-side door drive 3 arranged bearings 42 and the rotationally fixed in the lock housing 32 absorbed bearing ring 36 this rotational movement of the active wing 1 counterclockwise on the lock housing 32 with the nose 34 transfer.

This force effect of the rotary motion causes the nose 34 by the power transmission along its slope the overload slide 48 against the overload spring 50 pushed back and so within the recess 47 can shift counterclockwise. This shifts the bearing ring 36 with the blocking bodies 45 towards the teeth 37 of the fixed switching ring 35 which by the open wing with open 2 unconfirmed tripping device 10 and the thus fixed release slide 30 is supported. The teeth 37 the Schalring 35 first get into contact with the associated blocking bodies 45 and urge on further manual closing of the active leaf 1 the blocking body 45 towards the spring-loaded plunger 44 in the extended area of the wedge surface of the contour 41 back, causing the clamping of the locking bodies 45 between the bearing ring 36 and the camp 42 as far as it is solved, that the active leaf 1 slowed down. As a result, the degradation of kinetic energy occurs, causing the active leaf 1 not unnecessarily violently strikes.

Unlike triggering the lock 31 by closing the inactive leaf 2 , wherein the release slider 30 the switching ring 35 against the stationary bearing ring 36 rotates, turns in case of overload, the bearing ring 36 against the fixed switching ring 35 , However, there are advantageously no additional release elements in the lock 31 required for overload release, since the kinematic effect with respect to the locking body 45 is identical.
