Description

Austrian Patent Office AT510 907B1 2013-01-15

Description: The invention relates to a device for controlling the closing sequence of double-winged swing doors, one door wing being an underpinning, so-called passive leaf, and the second wing being an overturning so-called active leaf and a sliding rail door closer acting 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 over a certain specified by respective standard duration, the spread of fire from the room on one side to the room on the other side of the door. 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.

When open wing even open active leaf, for example driven by a spring, performs a leading edge closing movement, so this closing movement is stopped by the action of the device for controlling the closing sequence at a certain opening angle until the inactive leaf in its closing movement, the active leaf rushes far enough ahead, so that the correct closing sequence is ensured safely. When the inactive leaf is closed, the active leaf is freely pivotable. 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 U1.

In slide rail door closers protrudes a swivel arm of a door leaf to a sliding block, which is mounted longitudinally movably in a arranged on the upper frame part of the door frame slide rail. 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 predominant part 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 comprises the rod and depending on its adjustable skew position on the rod jammed or not. 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 ATP10 907 B1 2013-01-15

Stiff blocks of active 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 in a disturbingly wide open waiting position and must be kept there.

EP 458 034 B1 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 done by the inactive leaf when closing abuts directly with the upper edge of its door leaf to the pivotable two-armed lever and turns him back opposite to the previous pivotal movement. The advantage of this device is that so that 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 is 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 1096088 A2 shows a closing sequence control for double-leaf swing doors with slide rail door closer. Between the sliding block of the active leaf and a holding part acts a mechanical translation, by which movement of the one part is translated along the slide in oppositely directed movement of the other part along the slide rail. The translation is realized by a rope connecting the two parts and attached to the gangway side slide rail end pulley for the rope. Blockade of the movement of the holding member thus causes blockage of movement possibility of the sliding block of the active leaf in the slide away from the axis of rotation of the active leaf; Movement possibility of the sliding block on the axis of rotation of the active leaf remains to be possible. In order to be able to stop closing movement of the active leaf in an open position by the holding part for the purpose of closing sequence control, this open position must therefore lie in such a swivel angle range of the gangue, in which the sliding block of the active leaf is moved away from the pivot axis of the active leaf. Therefore, it is unfortunately often required in this construction, too, that the active leaf for the closing sequence control when opening the passive leaf must be brought into a disturbingly wide open standby position and held there.

EP 2 208 846 A2 also describes a closing sequence control for double-leaf doors, using a slide rail door closer. There are shown several versions of mechanical translations, which blockage of the movement of a holding part along the slide away from the axis of rotation of the active leaf, in blockade the movement of the sliding block of the active leaf on the axis of rotation of the active leaf translate. It is thus possible to set the opening angle at which the closing movement of the active leaf must be stopped for the purpose of closing sequence control to such an angle range, in the case of the sliding block of the active leaf during the closing movement of the active leaf Active leaf is moved in the direction of the pivot axis of the active wing out. Thus, this opening angle can also be set very small, when the sliding block of the active leaf moves during the last part of the closing movement of the active leaf in the direction of the pivot axis of the active leaf. The disadvantage is that the said translations in each case apply the angular position of the pivoting arm of the active leaf relative to the slide rail as an intermediate size of the translations. As a result, the overall function of the closing sequence control is directly dependent on the angular position of the swing arm of the inactive leaf relative to the slide rail. Thus, the ability to adjust 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.

EP 0613989 A2 shows a closing sequence control for double-leaf swing doors with slide rail closer. Blocking the closing movement of the active leaf is achieved by blocking the sliding block associated with it (referred to as "sliding roller") while moving the sliding block away from the pivoting axis of the active leaf. The blocking is performed by a hydraulic piston, to which inflow and outflow of hydraulic fluid is dependent on the position of the inactive leaf. Since the blocking of the closing movement of the active leaf must take place in an opening angle range of the active leaf, in which the sliding block of the active leaf moves away from the pivot axis of the active leaf, the holding angle of the active leaf must often be set distractingly wide open.

According to the AT 502965 A1 an opening and Schließfolgesteuerung is realized for two-leaf swing doors with Gleitschienentürschließer by the sliding blocks of the two wings are brought together in a transmission connection in the relevant opening angle range of the door, by which sliding a sliding block in oppositely directed sliding movement of the other Sliding block is translated. The design is applicable only in such pivoting ranges of door leaves, within which the direction of movement of the associated sliding block does not reverse with a uniform pivoting movement of a door leaf.

EP 1333142 A2 shows a two-leaf pivoting door with slide rail door closer, wherein the sliding direction of the sliding blocks in the slide during the last part of the closing movement of the door reverses. The occurring during the last part of the closing movement of the passive leaf sliding movement of the passive leaf belonging slider is translated via a translation mechanism which comprises a hook-shaped curved extension of the swing arm of the passive leaf and a two-armed, mounted on the slide lever, in the opposite direction movement of a control part, which in turn affects the active wing. It is thus achieved that the opening angle of the inactive leaf may be closed from the undershooting of the active leaf, can be placed in an angular range in which the sliding block of the inactive leaf moves during the closing movement of the inactive leaf on the axis of rotation of the inactive leaf. The waiting position of the active leaf must still be in such an angular range, causes in the closing movement of the active leaf sliding movement of the associated sliding block away from the pivot axis of the active leaf.

EP 1126118 A2 also shows a two-leaf hinged door with slide rail door closer, wherein the sliding direction of the sliding blocks in the slide during the last part of the closing movement of the door reverses. The occurring during the last part of the closing movement of the passive leaf sliding movement of the passive leaf belonging slider is translated via a translation mechanism which comprises a hook-shaped curved extension of the swing arm of the passive leaf, in motion of a control part, which in turn acts on the active leaf. It is thus achieved that the opening angle of the inactive leaf may be closed from the undershooting of the active leaf, can be placed in an angular range in which the sliding block of the inactive leaf moves during the closing movement of the inactive leaf on the axis of rotation of the inactive leaf. Nevertheless, the waiting position of the active leaf must be within such an angle range at which 3/12 Austrian Patent Office AT510 907B1 2013-01-15

Closing movement of the active leaf causes sliding movement of the associated sliding block away from the pivot axis of the active leaf.

Based on this prior art, the inventor has taken on the task of providing a device for controlling the closing sequence of two-leaf swing doors, wherein the one door is a unterschlagender, so-called passive leaf and the second wing a Überschlagender, so said active leaf and wherein a Gleitschienentürschließer 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 not directly the movement of the sliding block of the active leaf is used for holding the active leaf in an open position, but the movement of a sliding of the Active leaf separate, 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 directional movement of the other part (holding part or sliding block) is translated , As an improvement according to the invention compared to EP 2 208 846 A2, it is proposed to design said mechanical transmission independently of the position of the swing arm of the active leaf. As an improvement according to the invention over EP 1096088 A2, it is proposed to design the mechanical transmission such that blockage of movability of a part of the transmission connected to the holding part along the slide rail away from the pivot axis of the active leaf, blockage of movement of a part connected to the sliding block of the active leaf of the transmission to the pivot axis of the active leaf, causes.

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 on the basis of a diagram and a geometry sketch qualitatively the loading 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.

Fig. 2: shows a view from below of a first embodiment of a usable for the inventive device translation in installation situation.

Fig. 3: shows a view from below of a second embodiment of a usable for the device according to the invention translation in installation situation.

Fig. 4: shows a view from below of a third embodiment of a usable for the inventive device translation in installation situation.

The upper part of Fig. 1 is a partial sectional view from above of a pivoting active leaf 1, from the upper end face of a pivot arm 2 projects to a sliding block 3 in a slide rail 4, which is aligned horizontally, parallel to the plane of the closed active 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 4/12 Austrian Patent Office AT510 907B1 2013-01-15 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 is moved in the closing movement of the active leaf 1 only so long in the direction of the axis of rotation of the active leaf away, 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 to 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 constructions 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 sliding block 3 reverses with uniform angular movement of the active leaf. In contrast, according to the present invention, the pivoting angle range lying below the dead center angle is used, that is the opening angle range of the active leaf in which the associated sliding block 3 moves towards the pivoting axis of the active leaf during the closing pivoting 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 is moved 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 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 the purpose of controlling the closing sequence by blocking or allowing movement can be done according to the known from the prior art means on the basis of the interaction of the two each other door associated sliding blocks and therefore is not part of deeper discussions here. An exemplary mode of operation shows the aforementioned DE 36 04 091 C2.) In the inventive embodiment of Fig. 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 stationary in the slide rail 4 is arranged and two slidable in the slide rail piston 6.1, 6.2, to which the pressure of a common hydraulic fluid from opposite directions abuts forth, so that upon movement of a piston, the respective 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 compound 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 active leaf above a certain minimum opening angle is at least independent of the inactive leaf pivot.

In the inventive embodiment of Fig. 3, the required translation between the sliding block 3 of the active leaf and the said separate holding member 5 is formed by a threaded sleeve 16. The threaded sleeve is held in the slide 4 against longitudinal displacement but about its threaded axis, which is parallel to the slide rail direction, rotatable. 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, the end of the holding part 5 designed as a threaded bolt 5.1 projects into the second, complementary nut thread of the threaded sleeve 16. The threaded bolts 3.2, 5.1 are against rotation around held the thread 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 inactive leaf movable.

In the embodiment of 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 resolved 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 part 3.3 from the lever 2 6 slides off 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 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 present 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.
