    The invention relates to a device for controlling the closing sequence of two-leaf swing doors by means of a slide rail closer. By a holding part (5) the closing movement of the active leaf is blocked in a waiting position until the inactive leaf is at least approximately closed with the inactive leaf open. For this purpose, the active leaf and the inactive leaf are connected to one another via a holding part (5) whose mobility can be blocked or released by a barrier which is dependent on the position of the passive leaf. The holding part (5) is connected to the sliding block (3) of the active leaf via a mechanical translation (6, 16) which translates movement of the sliding block (3) along the slide rail (4) in oppositely directed movement of the holding part (5) and vice versa , The mechanical translation (6, 16) is independent of the position of the pivot arm (2) of the inactive leaf (1).

    description
    The invention relates to a device for controlling the closing sequence of double-winged swing doors, wherein the one door is a unterschlagender, so-called passive leaf and the second wing an overturning, so-called active leaf and wherein a Gleitschienentürschließer acts on the wings.
    The device according to the invention is particularly advantageous for such doors, which have to meet a security claim, in particular for fire doors with so-called panic and escape function, advantageously applicable.
    Fire doors must prevent the spread of fire from the room on one side to the room on the other side of the door for a certain amount of time specified by the relevant standard. Of course they can only do that if they are properly closed. Due to a fold, ie a projection, by which the active leaf protrudes beyond the fixed leaf, it is necessary for the proper closing of a double-leaf fire door that the wings are closed in the correct order. This is the case when, from the open state, the passive leaf is first brought into the closed position and only then is the active leaf. To ensure that this takes place safely even in case of fire, the wings are not only provided with a drive which automatically moves the door in the closed position, but also with a device for controlling the closing sequence. This device is intended to cause the two door leaves to be closed automatically in the correct order.
    If, when the inactive leaf is open, the likewise opened active leaf, for example driven by a spring, carries out a closing movement leading the fixed leaf, then this closing movement will be so long due to the action of the device for controlling the closing sequence at a certain opening angle.

    In order for this closing sequence control can work, the active leaf must be opened at the opening of the inactive leaf at least up to that opening angle at which he must wait while closing the passive leaf before he can be closed himself. The co-opening of the active leaf is typically achieved by means of a driver flap; this is a part which is usually pivotally mounted on the inactive leaf, projects to the moving leaf and pushes it in the first part of the opening movement of the passive leaf in an opening movement in front of him. Such a flap shows the AT 010 451 Ul.
    In sliding rail door closers a pivoting arm protrudes from a door leaf to a sliding block, which is mounted longitudinally movably in a sliding rail arranged on the upper frame part of the door frame. With the door closed, that end of the swivel arm, which is fastened to the door leaf, lies closer to the pivot axis of the door leaf than that end of the swivel arm which is connected to the sliding block. During the majority of the closing pivoting movement of the door leaf, the sliding block slides in the slide rail away from the axis of rotation of the door leaf.
    DE 36 04 091 C2 shows a device for controlling the closing sequence of two-leaf swing doors by means of a Gleitschienentürschließers. The sliding block of the active leaf is connected to a movable along the slide rod, which is guided by a clamping device which jams or releases depending on the position of the sliding block of the passive leaf. The clamping device is based on a indirectly supported on the slide plate, which includes the rod and dependent

The inclined position can be influenced both by the position of the sliding block of the inactive leaf, and by the force with which the sliding block of the active leaf is pressed against it, whereby an overload protection is also realized. The device is simple, inexpensive and robust. The disadvantage is that defined holding and releasing the movement of the active leaf only at such angles of the door wings are possible in which the sliding stones of solid leaf and active leaf during the closing movement of the wings are moved away from the axis of rotation of the respective wings. However, many doors are constructed so that during the last part of the closing movement of a door leaf, the sliding block belonging to the wing is moved towards the axis of rotation of the door leaf. The device according to DE 36 04 091 C2 then often forces that the active leaf for the closing sequence control when opening the passive leaf brought into a disturbingly wide open standby position and must be kept there.
    EP 458 034 Bl shows a device similar to DE 36 04 091 C2. The production of the deadlock in dependence on the position of the inactive leaf takes place with the aid of a pivotally mounted on the slide two-armed lever which extends vertically up to the height range of the door leaf of the passive leaf and is connected at one end via a connecting rod with the locking device for the active leaf , At the beginning of the opening movement of the inactive leaf belonging to the passive leaf sliding in the slide away from the axis of rotation of the passive leaf, it presses on the two-armed lever and pivots it so that mobility of said connecting rod will be released to the axis of rotation of the passive leaf, bringing mobility the active leaf is locked in its closing direction. The release of this lock is made by the inactive leaf when closing directly abuts with the upper edge of its door leaf to the pivotable two-armed lever and him

The advantage of this device is that this is the production or release of the deadlock of the active leaf depending on the position of the inactive leaf even at very small opening angles of the inactive leaf possible if the sliding block of the inactive leaf in the last part of the closing movement of the inactive leaf Rotary axis of the passive leaf moves. A remaining disadvantage is that when opening the inactive leaf, at least the active leaf still has to be opened beyond the dead center angle of its sliding block, ie beyond that angular range in which the sliding block of the active leaf moves away from the axis of rotation of the active leaf during the opening movement of the active leaf. Another remaining disadvantage is that the mentioned two-armed lever protrudes down into the height range of the passive leaf and comes into contact with its door leaf. The protruding lever and the impression he leaves on the door leaf are visually disturbing.
    EP 2 208 846 A2 describes a closing sequence control for double-leaf doors, using a slide rail door closer. For holding the active leaf in an open waiting position and / or for releasing the barrier of the active leaf against closing movement is not used directly the movement of the respective doors associated sliding blocks, but the movement of parts which along the slide relative to the sliding blocks also in opposite directions are movable. The movement of these parts is driven by the rotation of the pivot arm of the respective door closer. The function of the closing sequence control is thus given for both inactive leaf and active leaf even at very small opening angles of the wings, when the sliding blocks are moved during the last part of the closing movement of the associated door to the axis of rotation of the respective door leaf. Thus, holding the active leaf in the waiting position with a very small opening angle is possible.

    I REPLACED DN 17 lent as well as releasing the lock only with almost completely closed passive leaf. The disadvantage is that the function is directly dependent on the angular position of the pivot arms of the door relative to the slide rail. Thus, the adjustability to individual structural dimensions of the door is difficult. The design also causes unsightly from the slide rail protruding components and sometimes dangerous large lateral forces on parts of the slide rail.
    Based on this state of the art, the inventor has set itself the task to provide a device for controlling the closing sequence of two-leaf swing doors, the one wing is a unterschlagender, so-called still wing and the second wing a sweeping, so-called active leaf and wherein a slide rail door closer acts on the wings. It should be possible to set the required when the passive leaf waiting position of the active leaf in an open position to such an opening angle of the active leaf, in which the sliding block of the active leaf during the last part of the closing movement of the active leaf moves to the axis of rotation of the active leaf, as so also advantageously small opening angle for the waiting position of the active leaf are made possible. The disadvantages of the solution approach known from EP 2 208 846 A2 are to be avoided.
    To solve the problem as in the construction according to EP 2 208 846 A2 assumed that for holding the active leaf in an open waiting position not directly the movement of the sliding block of the active leaf is used, but the movement of a separate from the sliding block of the active leaf, separate holding part, which communicates with the sliding block of the active leaf via a mechanical transmission in such a way that movement of the one part (sliding or holding part) along the slide in opposite direction movement of the other part (holding part or sliding block) is translated. As inventive
    Page 5 | REPLACED | It is proposed to improve the said mechanical transmission independently of the position of the swing arm of the inactive leaf. Such translations can be well accommodated in the slide and an adaptation to the respective geometric relationships of doors is possible only by length adjustment of parts that extend in the slide rail.
    The invention is illustrated by means of sketchy drawings to different execution principles. The drawings are not meant to be limiting.
    Fig. 1: shows with reference to a diagram and a geometry sketch qualitatively the movement of the slide rail end of a belonging to a moving leaf pivot arm in dependence on the opening angle of the active leaf.

    The upper part of Fig. 1 is a partial sectional view from above of a pivoting leaf 1, from the upper end face of a pivot arm 2 to a sliding block 3 in a slide 4 projects, which is aligned horizontally, parallel to the plane of the closed leaf. For reasons of visibility of the slide rail 4 in Fig. 1, only the position indicated by dashed lines.

    The lower part of FIG. 1 is a diagram showing the displacement s of the sliding block 3 relative to its position with the active leaf 1 closed, as a function of the opening angle of a moving leaf 1. Positive displacement means increased distance of the sliding block to the axis of rotation 11 of the active leaf.
    It can be seen that in the illustrated geometric relationships of the sliding block 3 during the closing movement of the active leaf 1 only so long in the direction of the axis of rotation of the active leaf is moved, as long as the opening angle of the active leaf is more than about 15 °. At a smaller opening angle of the sliding block 3 is moved away from the axis of rotation.
    Fig. 1 applies regardless of whether a device according to the invention or a device according to the prior art is used.
    In most designs according to the prior art, only that pivoting range of the active leaf 1 can be used for the control of the closing sequence, which is above that dead center at which the linear direction of movement of the associated Gleitsteines 3 reverses with uniform angular movement of the active leaf. In contrast, according to the present invention, pivoting angle range lying below the dead center angle is used, that is to say the opening angle range of the active leaf in which the associated sliding block 3 moves towards the pivoting axis of the passive leaf during the closing pivot movement of the active leaf. To do this, unlike most prior art designs, it is not the direct movement of the sliding block 3 that is used to control the closing sequence, but the movement of a separate holding member 5 (see FIGS. 2 and 3) moved relative thereto. which in the relevant part of the closing movement of the active leaf, driven by a translation mechanism by the movement of the sliding block 3, in the

    Slide rail 4 is moved away from the pivot axis of the active leaf.
    The interaction of this separate holding part 5 with a part of the passive leaf for controlling the closing sequence by blocking or allowing a movement can be done according to the means known from the prior art on the basis of the interaction of the two each other door associated sliding blocks and is therefore here not part of deeper discussions. An exemplary mode of operation shows the aforementioned DE 36 04 091 C2. )
    2, the required translation between the sliding block 3 of the active leaf and the said separate holding part 5 is formed by a hydraulic unit 6 which is fixedly arranged in the slide rail 4 and two slidable in slide rail piston 6.1, 6.2, at to which the pressure of a common hydraulic fluid is applied from opposite directions, so that upon movement of one piston, the other piston is moved in the opposite direction. A piston 6.1 is connected to the sliding block 3 of the active leaf, the second piston 6.2 is connected to the said separate holding part 5.
    In a preferred embodiment, the connection of the sliding block 3 with the piston 6.1 is formed so that it is released when a force threshold is exceeded in the pulling direction. In the example shown, this is symbolized by an indicated snap connection 3.1, 6.3. This ensures that the
    In any case, the active leaf above a certain minimum opening angle is pivotable independently of the inactive leaf.
    In the embodiment according to the invention of FIG. 3, the required translation between the sliding block 3 of the active leaf and the said separate holding part 5 by means of a threaded-dehülse 16 is formed. The threaded sleeve is in the slide rail 4th

From the two end faces of the threaded sleeve 16 ago each have a threaded bore in the threaded sleeve 16, wherein the two threads are opposite to each other common.
    A connected to the sliding block 3 threaded bolt 3.2 with a very steep thread protrudes from the one end face into the threaded sleeve 16 and is there with a complementary to its male thread nut thread in threaded engagement.
    From the second end face protrudes designed as a threaded bolt 5.1 end of the holding part 5 in the second, complementary to the nut thread of the threaded sleeve 16. The threaded bolts 3.2, 5.1 are held against rotation about the threaded axes. By moving a threaded bolt in the nut thread linearly, the threaded sleeve 16 is rotated about the threaded axis and the second threaded bolt is linearly displaced opposite to the first threaded bolt.
    By the connected with the sliding block 3 threaded bolt 3.2 is made shorter than the path of the sliding block 3 in the opening movement of the active leaf, can be easily achieved that the active leaf above a certain minimum opening angle is completely independent of the fixed leaf movable.

    In the embodiment according to the invention of Fig. 4, the required translation between the sliding block 3 of the active leaf and the said separate holding part 5 by means of a pivotable two-armed lever 26 is formed. The lever 26 is held in the slide rail 4 against longitudinal displacement, but rotatable about its pivot axis, which is normal to the slide rail direction. The first end of the approximately normal to the slide rail longitudinally aligned, straight lever 26 can be hooked with a hook part 3.3, which is pivotally held on the sliding block 3 and is held in the absence of other forces by a spring in a preferred position. The entanglement occurs only when the sliding block 3 has been moved far away from the axis of rotation of the active leaf and is then moved back to the axis of rotation of the active leaf, as is the case towards the end of the closing movement of the active leaf. The holding part 5 is pivotally connected via a connecting piece 5.2 with the end of the second lever arm. If the hook part 3.3 is hooked to the lever 26 and the holding part 5.2 is in the locked position, the sliding block 3 of the active leaf can not be moved to the pivot axis of the active leaf and thus the leaf can not be closed. The blockage is released when either the lock of the holding part 5 is released - so if the inactive leaf comes to the closed position or if by strong drive the rotation of the active leaf triggers the overload protection of the lock.
    By the hook portion 3.3 slides off the lever 2 6, when the sliding block of the active leaf to a certain extent from the lever 26, also in this embodiment, the active leaf above a certain minimum opening angle is completely independent of the inactive leaf movable.

    In addition to the discussed embodiments of translations, there are certainly a variety of other ways to do so. For example, sliding block 3 and holding part 5 may each have an extension formed as a rack, wherein the two extensions are on opposite sides of a gear which is rotatably mounted in the slide, with the gear engaged.
    In all embodiments, the device can be adjusted by Längenein-adjustability of the holding part 5 or the connecting part between the sliding block 3 and the translation mechanism to the respective geometric relationships of a door.
    For reasons of reliability in case of power failure and fire, it makes sense at least to apply only mechanical transmission elements for driving the required relative movement between the individual parts involved in the control of the closing sequence.
