Description

The invention relates to a device for closing sequence control of a two-leaf door with a moving leaf and a stationary leaf, wherein both door wings are each pivotally connected to a wall region adjacent to the door, in particular a door frame to a stationary bearing axis.

Double-leaf doors are often used in passage areas that have only temporarily high transmission frequencies. Basically, a distinction is made in the case of double-leaf doors between the active leaf and the fixed leaf. The active leaf is the door leaf that is normally used for walking purposes etc. In contrast, the fixed wing is often only opened in special cases when increased access, such as in an emergency for evacuation purposes or for carrying wide objects, etc., is required. At the same time, for example, for fire protection reasons, in order to counteract, inter alia, the spread of smoke, in the case of an emergency, a double-leaf door is desired. Two-leaf doors are therefore also very common fire doors.

Both wings usually have at their mutually facing side edges in each case a fold to allow, among other things, a particularly tight closing of the two-leaf door. The fold of the active leaf is arranged on the door leaf side facing the opening direction and overlaps in the closed state the inactive leaf. The fold on the inactive leaf, on the other hand, is arranged on the door leaf side of the inactive leaf facing the door closing direction and overlaps the active leaf. However, the fold requires that the inactive leaf can not be opened or closed independently of the position of the active leaf. The active leaf must rather be open in a certain minimum opening angle, so that the inactive leaf can be pivoted past with its fold on the wing and its rebate. A generic device for Closure sequence, as for example in the considered as the closest prior art DE 40 16 283 C1 is now disclosed, ensures that the open passive leaf in front of the active leaf can take its closed position. Thus, depending on the position of the inactive leaf, the closing sequence control holds the active leaf in the minimum opening position until the inactive leaf is pivoted past the active leaf, in particular into its closed position, in order to ensure the sequence of the door wings required for the door closing. Also for storage cabinets are closing sequence controls for cabinet doors known, such as in the US 3,895,849 A disclosed.

The pivoting of the two leaves is made possible in each case via an external door hinge. The door leaves are each pivotally mounted on the adjacent wall area, in particular door frame, by means of the door hinge. To the axis of rotation formed by the door hinge, hereinafter referred to as bearing axis of rotation, the door is pivotable.

Generic devices for closing sequence control comprise a blocking device with which the active leaf in the minimum opening position in the door closing direction can be determined, wherein the minimum opening position of the active leaf is at least chosen so that the inactive leaf can still swing past the partially opened active leaf. Furthermore, a triggering device controlled by the inactive leaf is provided which releases the blocking device at a predetermined position of the inactive leaf. The predetermined position of the passive leaf, in which the triggering device triggers, is expediently chosen so that the active leaf can no longer swing past the inactive leaf. It is ideal if the inactive leaf triggers the triggering device in the closed state.

A generic device for closing sequence control of a two-leaf door further comprises a arranged between the active leaf and the wall area door closer with a force acting on the active leaf locking arm. The locking arm thus connects the wall area with the door leaf or the door leaf. In this case, both the door leaf-side and the wall-side mounting of the door closer is possible. According to the invention, a sliding rail door closer with a slide rail is used, as will be described in more detail below. If nachschend thus reference is made to a door closer, this refers to a Gleitschienentürschließer. The slide is usually wall side and the door closer door leaf side. The door closer acts on the closing arm with a closing force, ie a force which is converted via the closing arm into a closing movement of the active leaf. The locking arm is hinged at its first end region about a door closer rotation axis rotatable on the door closer and at its second end region about a rotation axis, hereinafter also called guide axis of rotation, rotatable stored. In the door closer, a compression spring or similar is usually present, via which the closing force is generated and the rotational movement of the closing arm is driven.

The bearing rotation axis, the door closer rotation axis and the guide rotation axis are arranged in a projection in the plane orthogonal to the axial direction of the bearing rotation axis in series and further arranged such that they together with the two intermediate areas form a toggle whose fixed pivot point is the bearing axis of rotation and whose further pivot points are formed by the door closer rotation axis in the guide axis. The three axes of rotation are thus arranged in a specific geometric positioning to each other. By definition, this particular positioning results from the projection of the three axes of rotation in the axial direction, i. their extension in the direction of their respective axis of rotation forming axis. The projection takes place in a plane orthogonal to the axial direction of the bearing axis of rotation, d. H. usually horizontal, is arranged. The three axes of rotation thus form, in the above-mentioned projection mode, three pivot points in this projection plane which are connected in series via the components lying between the individual pivot points, which do not necessarily lie on the line of action or must correspond to the direct connecting line between the three pivot points , The three pivot points act together in the form of a toggle lever. This is the case for example in the projection even if the components forming the three axes of rotation or the components lying between the axes of rotation are arranged at different distances, obliquely or otherwise irregularly relative to one another with respect to the projection plane. According to the invention, the arrangement of the three axes of rotation in the form of a toggle lever in the projection plane is crucial. This projection level thus represents a total reference system whose position is determined by the axial direction of the bearing axis of rotation. The determination of the position of the individual pivot points set out above then results from the positioning of the pivot points in this reference system. The term pivot point thus refers to the position of the axis of rotation in the projection plane and the term axis of rotation on the spatial arrangement.

About the bearing axis of rotation of the door hinge of the active leaf is hinged to the wall area adjacent to the active leaf. Under this wall area is to be understood as a whole of the area which is fixedly adjacent to the active leaf at least from the door hinge side. Under the wall area falls in addition to, for example, a concrete wall and the usually existing door frame. Further, the wall area is not limited in size. Thus, the wall area can also be formed by a corresponding post etc. Relative to the usually stationary wall area of the active leaf and the inactive leaf are pivotable. The pivot point formed in the projection plane of the bearing axis of rotation is therefore not displaced in this plane and thus formed stationary.

The other two pivot points (formed by the guide axis of rotation and the door closer axis of rotation) are arranged in the projection plane in series with the pivot point of the bearing axis of rotation, wherein either the pivot point of the door closer rotation axis or alternatively the pivot point of the guide axis of rotation in the projection plane is operatively connected to the pivot point of the bearing axis of rotation and in the center of the array is located. The order is essentially determined by the type of arrangement of the door closer and the corresponding articulation of the locking arm. If the door closer is arranged, for example, on the door leaf, as is the case in particular when using a slide rail door closer, the bearing rotation axis is operatively connected to the door closer rotation axis essentially via the region of the door leaf therebetween. In the case of the door leaf-side arrangement of the door closer, the pivot point of the door closer rotation axis thus forms the pivot located between the pivot points of the guide axis of rotation and the bearing axis of rotation (corresponding to the "knee" in the toggle lever). If the door closer, however, arranged on the wall side, the locking arm is hinged on its guide axis of rotation on the door leaf, so that the pivot point of the guide axis between the two pivot points of the bearing axis and the Türschließerdrehachse is arranged (here thus forms the fulcrum of the guide axis of rotation of the "knee").

According to the invention, the door closer is a slide rail door closer in which the closing arm is articulated via the guide axis of rotation to a slider which is mounted linearly displaceably in a guide rail. When Gleitschienentürschließer both the fulcrum of the guide axis of rotation and the pivot point of the door closer rotation axis are not stationary. In contrast, in the Scherengestänge- or Gelenkarmtürschließern also the fulcrum of the bearing axis of rotation at the other end of the toggle lever in the projection plane opposite fulcrum, which is formed either by the Türschließerdrehachse or the guide axis of rotation, stationary in the projection plane.

The two lever arms of the toggle lever, which are pivotable relative to each other over the central pivot point arranged in the projection plane between the two outer pivot points, are formed by the regions which lie between the central pivot point and the respective outer pivot points in the projection plane or physically connect these pivot points with one another. The lever arms of the present toggle lever are to be understood in particular as a line of action in the projection plane, while the concrete physical embodiment may vary on the double-leaf door. Thus, the pivot points or axes that are in functional connection with a lever arm also do not have to be structurally connected to one another along the direct connection / action line. Rather, the decisive factor is the presence of such a Hebelarmverbindung that allows a corresponding power transmission through the structural connection between the individual pivot points. With respect to the lever arm, which lies between the door closer rotation axis and the guide rotation axis (or the respective pivot points in the projection plane), this is essentially formed by the closing arm. With respect to the second lever arm, which is depending on the arrangement variant between the door closer rotation axis and the bearing axis of rotation or the guide axis of rotation and the bearing axis of rotation (or in the projection plane the respective pivot points), this comprises, if the door closer is arranged for example on the door leaf, the door closer itself as well as lying in the projection plane between the two pivot points areas of the door panel and thus, for example, parts of the door closer housing.

However, the previously known from the prior art devices for closing sequence control of two-leaf doors have several disadvantages. On the one hand, they require that special demands be placed on the closing arm in terms of stability and resistance, since both the guidance of the active leaf and the blocking of the active leaf in its minimum opening position can be achieved solely via the closing arm. In addition, hitherto known devices for closing sequence control of a two-leaf door, especially in the use of Gleitschienentürschließern, often not in the same way for the door hinge side and for the Türbandseitigeseitige assembly. In the door hinge assembly mounting the active leaf pivots, for example, to the door closer and, if present, slide rail opposite side of the active leaf. The door hinge and the door closer are thus mounted on opposite sides of the door leaf of the active leaf in this arrangement variant. In the band-side mounting the door closer and the door hinge are both arranged on the same side of the door leaf. In particular, in the door hinge-side mounting in which the door hinge and thus the bearing axis of rotation or formed in the projection of the bearing axis of rotation pivot point on the opposite door leaf side is formed as the fulcrum formed by the Türschließerdrehachse, resulting in particular slide rail door closers gear-induced hyperextension of the toggle lever when closing or opening the active leaf, whereby the slider guided in the slide after driving through the maximum stretched position at an opening angle of, depending on the design, usually about 20 ° to 30 ° reverses its direction of movement in the slide rail.

The previously known blocking devices of such Gleitschienentürschließer usually act on a blockade of the slider or sliding block in the slide rail. However, this possibility comes to its limits when the movement of the slider in the slide at a closing movement of the door is not linear or alone in one direction when closing and only in the opposite direction when opening, as for example, especially in the door hinge side mounting the Case is. As a result, especially when using slide rail door closers mounted opposite one another, the minimum opening position must be selected for a comparatively large door opening angle in order to be able to reliably detect the closing movement of the side wing via the slider movement. However, this adversely affects the reliability of the closed-loop control. The invention is also intended to solve this problem.

The solution of the problem is achieved with a device for closing sequence control according to the independent claim. Preferred developments are specified in the dependent claims. An essential aspect of the invention is that the blocking device is articulated via a locking lever on the toggle lever between its two outer pivot points in the projection plane and the locking lever is designed to transmit a blocking force from the blocking device to the toggle lever. A central aspect of the invention thus lies first in the fact that the blocking device is articulated on the closing arm between its two outer pivot points, ie in the region of the lever arms and the central pivot point; and, for example, no longer acts on the slide hinged at the end hinged end slide. For this purpose, the blocking device comprises a separate and, in particular in the projection plane, pivotable locking lever which transmits the blocking effect or blocking force exerted by the blocking device on the toggle lever and thus ultimately on the door leaf. To transmit the blocking effect of the locking lever is lockable, in particular at least in its direction of movement during a closing movement of the active leaf, so in at least one direction. Thus, a particularly versatile device for closing sequence control is obtained, which is particularly suitable for the Türbandgegenseitige installation, although a door hinge side mounting is possible.

Preferably, the locking force is transmitted from the locking lever over the entire detection range obliquely on the toggle lever or introduced. Under a, in particular with respect to the projection plane, oblique transmission of the blocking force is an arrangement of locking lever and toggle to each other to understand, in which the tangent in the direction of movement of the articulation point between the toggle lever and the locking lever in the desired locking position, in particular the minimum opening position, and the line of action of Locking lever in the projection plane obliquely, ideally perpendicular, to each other. Especially for Gleitschienentürschließer is in this context note that the articulation by the locking lever in the projection plane also preferably takes place obliquely to the displacement of the slider. With regard to this type of door closer, the invention also includes an articulation at the pivot point of the guide axis of rotation itself (even if this lies outside with respect to the toggle lever). This is by definition covered by the phrase "between the two outer pivots". The inventive effect when using a Gleitschienentüröffners is the result that was taken from the previous by acting on the run in the slide slide distance and rather a diversion of the movement of the toggle lever and in particular of the locking arm is achieved via the additional locking lever, as Result an ideally angle-proportional (with respect to the door opening angle) movement takes place, which is used as an attack or blocking possibility for the blocking device. Thus, the decisive for the initiation of the blocking force part on which the blocking device can move over the entire pivoting range of the active leaf in each case in one direction, regardless of the band-side and band-mutual attachment of the device for closing sequence control of a two-leaf door.

At the same time this device thus enables a particularly accurate locking of the active leaf in the minimum opening position. This also applies in particular in the event that the door closer used is a Gleitschienentürschließer. By the articulation of the locking lever on the toggle lever between the projection in the two outer pivot points succeeds particularly elegant to ensure that the locking lever over the entire closing movement of the active leaf a movement in one direction, even with an overstretching of the locking lever passes. This makes it possible, in particular in the case of a band-side mounting, to precisely match the braking behavior of the blocking device, in particular in the area of the closing angle <40 °, very particularly <30 ° and especially also in the range <20 °. A consequence of the toggle arrangement of the three pivot points relative to one another is that the regions between the two outer pivot points of the toggle lever, when pivoting the toggle lever from its position with the door open to its position with the door closed, in any case carry out a partial movement that over the entire opening process into one Direction and over the entire closing process in the other direction is oriented. This is especially true when the pivot point of the guide axis during the closing or opening movement of the active leaf in the projection plane is not performed over the entire pivoting operation in one direction, as is the case for example in the band mutual installation of Gleitschienentüröffners. By means of the additional locking lever, it is possible to derive this partial movement from the knee lever and to provide as a point of attack for the blocking device. The articulation of the locking lever on the toggle is carried out preferably obliquely to the sliding track of the slider in the projection plane, ideally rectangular. Another central idea of the invention is therefore to provide a locking lever which acts in such a way on the toggle that it is provided for blocking or blocking the movement of the door in the door closing direction, wherein the locking lever is designed and arranged such that it its blocking force obliquely applied to the toggle lever with respect to the path of movement of a point on the toggle lever, which moves in one direction over the entire opening path and in the opposite direction over the entire closing path. In other words, the locking lever of the toggle lever according to the invention enables a rectified over the entire closing process, ideally angularly proportional, to dissipate movement, on which the blocking device acts for blocking purposes.

The advantages of the invention are especially evident when the door closer is mounted on the hinge opposite side, since especially there the motion reversal of the slider can be observed in the slide during the closing or opening operation. The inventive arrangement of the locking lever between the toggle lever and the blocking device makes it possible to bypass the occurring at Gleitschienentüröffnern "negative", ie opposite to the initial opening movement, Gleitweg the slider. The articulation of the locking lever on the knee lever according to the invention makes it possible to brake the Zuschwenkbewegung the toggle lever alone in a direction of action. Thus, the braking of the active leaf can be effectively achieved even with the band mutual installation at comparatively small opening angles. The previously required particularly in the band mutual assembly previously large locking angle of the active leaf, which was caused by the reversal of direction of the braked sliding block in the use of Gleitschienentürschließern can thus be significantly reduced with the inventive arrangement. In particular, even with the band mutual assembly of the door closer, the device according to the invention for closing sequence control can therefore be adjusted so that the active leaf is detectable in an opening angle of <20 °, especially <10 ° and even <5 ° by the locking lever, so that the inactive leaf can swing from its open position to its closed position on the active leaf to ensure a closing order. In the previously known closing sequence controls, which usually act on guided in a slide sliding block of a door closer, so far findings could be achieved at an opening angle> 30 ° due to the reversal of movement of the sliding block in the slide. In principle, the locking lever can for example also be articulated directly on the door leaf in the region of the knee lever.

The storage of the locking lever on the wall area is particularly advantageous in view of the required installation work. The pivot bearing of the locking lever is arranged in this embodiment together with the blocking device on the fixed wall portion. With its other end, the locking lever is articulated to the toggle lever via a suitable connection.

Basically, the locking lever can articulate the toggle lever between its two outer pivot points in the projection plane. However, the locking lever preferably engages in the region of the closing arm on the toggle lever. This is advantageous, for example, in that suitably suitable connecting means, etc., can already be attached ex works to the locking lever and to the locking arm. Existing door closers can then be retrofitted accordingly and a complete replacement of the door closer is not required. This can considerably speed up installation work.

Preferably, the locking lever and the locking arm are arranged together in a plane, in particular in the form of a horizontal gearbox, in particular a four-bar linkage. The drive of the transmission thereby forms on the locking lever a blocking force performing door closer. Essential for this embodiment is that the movement of the locking lever and the locking arm substantially in a horizontal plane to each other. As a result, the space requirement of this embodiment in the vertical direction is particularly low. This embodiment is thus particularly space-saving feasible. Similarly, the side of the passive leaf may have such a transmission with a corresponding door closer. The geared configuration of the inactive side will be explained in more detail below.

The concrete design of the locking lever can be realized in various ways. Particularly advantageous is an at least two-armed locking lever has been found, wherein the one arm is articulated on the knee lever and the other arm to the blocking device. The linkage can be done indirectly and alternatively also directly. In this embodiment, the locking lever further, preferably in the intersection region of the first and the second arm, a pivot bearing with a separate axis of rotation (locking lever pivot axis) and thus also a separate pivot point in the projection plane orthogonal to the bearing axis. The two-armed locking lever is thus stored separately from the articulation on the toggle lever and on the blocking device.

Preferably, the two arms of the two-armed locking lever are at an obtuse angle to each other. It is also advantageous to form the two-armed locking lever in one piece. As a result, the locking lever acquires a particularly stable constitution. Alternatively, the locking lever Of course, be multi-part, which facilitates, for example, the adjustment options of the device according to the invention for closing sequence control to different double-leaf doors.

The pivot bearing of the two-armed locking lever is preferably arranged on the gangway-side slide rail of a slide rail door closer, especially on an end face of the slide rail. In this way, a compact installation unit can be obtained very easily, in which essential elements, in particular the locking lever, are already pre-installed.

The concrete design of the compound of the locking lever with the toggle lever, generally referred to above as articulation, can be realized in different ways. In principle, overlapping and overlap-free connection possibilities are included within the scope of the invention. Preferably, a control slope is provided for the articulation of the locking lever on the toggle, along which a guide element is guided. The guide element is for example a protruding bolt. Control slope and guide element are opposite each other, preferably on the locking lever, the control slope and the toggle preferably the guide element arranged. This type of articulation allows a particularly flexible use of the device according to the invention for closing sequence control and also allows a certain play in the arrangement of the individual elements by the use of a control slope, whereby the handling of the device according to the invention for closing sequence control of a two-leaf door is greatly facilitated.

It is particularly elegant to integrate the control slope into a slot guide. In this way, it is ensured that the locking lever is always guided on the toggle, since the slot surrounds the guide element in the management plane (ideally the pivot plane of the locking lever and especially additionally parallel to the projection plane) and thus in each direction of movement in the management level a guide the guide means is guaranteed in the slot. As long as the locking lever exerts no locking force on the knee lever, the locking lever is therefore also moved passively with the toggle lever due to the oblong hole engagement. The control slope is formed in this case in the form of a guide means in the oblong hole plane circumferential control slope, which is penetrated by the guide element in a suitable manner at least partially.

Another way to ensure the position of the locking lever over the entire opening process is to apply the locking lever counter to the direction of movement of the articulation point on the toggle lever in a movement of the active leaf in the opening direction with a spring force. In this case, the spring force is preferably substantially smaller, in particular by a factor of 5 or more, than the door closing force exerted by the door closer, since otherwise the door leaf could be pressed by the Federkraftbeaufschlagung the locking lever. Although the latter embodiment is basically possible, but requires an additional decoupling, which controls the timing of Federkraftbeaufschlagung in particular with the closing operation of the door. If the active leaf is opened and thus the door closing force exerted by the door closer manually overcome, the spring action of the locking lever thus presses this in the opening direction of the active leaf. In this embodiment, the positioning of the locking lever is thus actively determined by the interaction of the spring action of the locking lever in the opening direction of the active leaf and the movement of the active leaf. A movement of the locking lever "in the opening direction of the active leaf" is in principle to be understood in the manner that it indicates the movement that performs the locking lever when the active leaf is opened. This does not mean that this movement is parallel to the opening movement of the door leaf. Rather, this depends on the specific arrangement (the same also applies to the movement of the locking lever in the closing direction of the active leaf).

In principle, it is possible to carry the locking lever on the toggle lever over the entire opening path of the door leaf (for example, from a door opening angle of 0 ° to a maximum of 115 °). The blocking device is preferably formed in this embodiment in such a way that a determination of the locking lever by the blocking device and thus a determination of the toggle lever or the active leaf over the entire pivoting range is possible. Since, however, the opening sequence control essentially depends on those opening angles of the active leaf at which the inactive leaf can no longer swing past the active leaf (this basically depends on the specific design of the leaf, but usually this range is at door opening angles <20 °), It is also within the scope of the invention to form the locking lever in such a way that it is carried along only for this limited area on the moving leaf. The guide element and the control slope are formed in this embodiment accordingly in such a way that the guide means released from the exceeding of a predetermined opening angle or disengages from the control slope. Rather, the control slope remains in a specific position (catching position or catching position) in which it can catch the guide means during the closing process in a timely manner. This position is chosen so that the active leaf is held in an opening angle which is large enough that the inactive leaf can swing past the active leaf. Subsequently, this position of the locking lever is also referred to as a catching position.

For this purpose, a locking lever stopper is present against which the locking lever strikes in the opening direction or its direction of movement when the active leaf is opened. The locking lever stop is ideally arranged on the device for closing sequence control, that the locking lever abuts at an opening angle of the active leaf <40 °, in particular <30 °, especially <25 ° and especially <20 ° to the locking lever stop or is caught by this. In this way, the locking lever must not be carried over the entire opening path of the active leaf away and at the same time it is ensured that the active leaf can be kept in time when closing the locking lever or the blocking device in the minimum opening position.

Since doors, in particular with regard to the seam widths, the door frame or door leaf widths, etc., may vary greatly, the use of a, in particular with regard to the opening angle of the locking lever stop, adjustable locking lever stopper has proven to be particularly advantageous. An adjustable locking lever stop makes it possible to adapt the device of the closing sequence control to the individual circumstances in a particularly simple manner. Adjustments exist in particular with regard to the collection position or with respect to the door opening angle, in which the active leaf is detectable via the locking lever maximum.

In a further embodiment of the invention, the locking lever is mounted with its locking lever bearing pivot axis on a slidably guided in a slide slider, wherein the slider is lockable via the blocking device. The basic design of the slide rail and guided therein slider can be based for example on the already known slide rail door closer. In contrast to the known sliding rail door closer, however, it is inventively provided to additionally integrate the locking lever in the device for the closing sequence control, which is articulated in the manner set forth above on the toggle. An adjustment of the locking lever is possible in a simple manner by a displacement of the corresponding slider along the slide rail.

Already from the above statements it is apparent that it is particularly advantageous for the invention, when the door closer is a slide rail door closer, the closing arm has a relative to the closing arm rotatably mounted and guided in a slide at its end portion opposite the door closer. Particularly in the case of a slide rail door opener, the end point of the closing movement of the active leaf is problematical to determine in the case of band-side mounting, since the slider, towards the end of the closing movement, reverses its direction of movement in the slide rail. The closing sequence control device according to the invention avoids this problem by integrating the locking lever in the manner described above. This makes it possible to use Gleitschienentürschließer in particular for the tape-mutual installation, even if in principle a band-side mounting is possible.

Structurally, it is advantageous if the slide guides both the slider of the locking arm and, if present, the slider of the locking lever. In this way, a total of only one slide is required, which not least the installation cost can be reduced.

In principle, it is also possible that the locking lever articulates the toggle lever in an area that is structurally formed in the projection plane of the door leaf of the active leaf. This embodiment is particularly advantageous for such a locking lever, which is mounted in the manner described above on a slider slidably guided in a slide rail. The locking lever is arranged in this embodiment in the pivoting plane in the area which is bounded by the toggle lever and the door frame. In this way, thus a particularly space-saving arrangement of the toggle lever together with the locking lever is possible.

Another advantageous basic idea of the invention lies in the design of the triggering device of the device for closing sequence control. In principle, the triggering device can be executed in the manner known from the prior art. Part of the triggering device is usually another door closer, preferably also a slide rail door closer, which is arranged between the adjacent wall portion and the inactive leaf. This ensures that even the inactive leaf is subjected to a door closing force, so that it is pressed into its closed position. To open the passive leaf, therefore, at least this door closing force must be overcome.

It has now been shown that the concept of the locking lever with respect to the active leaf can in principle also be transferred in principle to the triggering device. In a preferred embodiment, the triggering device therefore engages a slide rail via a latching arm and a slider, the bearing axis of the door leaf side door hinge, the door closer rotation axis of the door leaf side door closer, and the guide rotation axis of the slider projecting in the plane orthogonal to the axial direction of the bearing rotation axis of the stationary leaf arranged in such a way that together with the two intermediate areas they form a toggle lever whose fixed linkage is the pivot point of the bearing axis relative to the projection plane, and whose further pivot points are formed by the door closer rotational axis and the guide axis, wherein a pivoting control lever is provided , which is hinged to the toggle lever and is adapted to the triggering device in response to a fixed position of the passive leaf operated. The above advantages set out for the locking lever also apply in principle to the pivoting control lever of the triggering device. This concerns in particular the determination of the trigger point in wall-mounted mounting of the door closer, as here, too, performs the slider in the slide to the end of the closing movement of the inactive leaf an opposite movement. Due to the special articulation of the pivoting control lever on the toggle lever, however, it is possible to derive a rectified movement over the control lever from the toggle lever and to use to control the triggering device.

Preferably, a pull rod between the pivot control lever and the triggering device is further arranged for actuating the triggering device, which is designed in such a manner that it actuates the triggering device to train. The integration of a pull rod instead of the previously widely used push rods is advantageous in that the material load of the control linkage is thereby significantly reduced and so avoided, for example, bending or similar damage, in particular a buckling of the rod, which could lead to erroneous functional sequences, in advance can be. The pull rod is ideally arranged in such a way that it lies substantially in one plane with the swivel control lever and the closing arm and forms together with this a horizontal gear.

The blocking device can be designed in the usual way. For example, the blocking device preferably has a clamping device which, in its clamping position, causes the blockage or locking, and in its release position is in the non-blocking state. The specific design of the functional connection between the blocking device per se and the locking lever can vary. For example, it is possible to connect the locking lever directly to the blocking device, in particular the clamping device. Preferably, a locking member is articulated on the locking lever, which establishes the functional connection to the blocking device. In this way, the device for closing sequence control can be easily adapted by simply adapting the locking member to different types of doors. An individual adaptation, for example, the locking lever, the blocking device and other components, however, is not required. The locking member may for example be a corresponding, possibly multi-part, locking bar.

In a further embodiment of the invention, wherein the blocking device comprises a locking member hinged to the locking lever, in particular a locking rod (23), and wherein the locking member is connected via an adjusting rod with a clamping device, the adjustment options are further simplified. Here is an adjustment rod available, which is a length adjustment the locking member or the connection between the locking lever and the blocking device allows. For this purpose, the adjusting rod, for example, a plurality of spaced-apart fastening means, such as in the embodiment as a hole bar with a plurality of through holes, which are provided for receiving a plug pin. In this way, the closing sequence control according to the invention can be adapted to different door widths by the respective setting, for example the length of the adjusting rods. It is therefore no longer necessary to provide for each door width a special device for closing sequence control. The essential inventive idea of this development is that a separate connection component is present, via the sole Längenanpässung the entire device for closing sequence control to the respective door width is customizable.

In terms of production technology, it is advantageous if the pull rod, at least in its articulation areas and in particular in its entirety, is of identical design to the locking member, in particular the locking bar. In this case, the articulation region comprises the regions of the drawbar via which it is connected to the components that are functionally connected to it. In this way, the number of different parts of a device according to the invention for closing sequence control can be significantly reduced. In addition, in particular this embodiment of the invention makes it possible to arrange the device for closing sequence control both on the right and on the left side (relative to the active leaf). Only the location of the blocking device and the triggering device must be interchanged.

According to the invention, it is possible to mechanically connect the blocking device and the triggering device directly to each other. Alternatively, however, it is also possible to provide a transfer means between the blocking device and the triggering device, which transmits an actuation of the triggering device by the inactive leaf to the blocking device in such a way that it switches from the blocking position to the release position. Such transmission means may be, for example, floor cables, electrical lines, etc. In this way, for example, the area between the blocking device and the triggering device (usually centrally in the upper region of the door frame) are kept free, so that in addition components such as alarm, emergency exit displays or the like can be integrated at this point.

In the forms of representation listed below, the same components are provided with the same reference numerals. Furthermore, for reasons of clarity, in some cases not every component provided with a reference symbol in a figure is also provided with a reference symbol in all other figures, even if it is visible there.

The double-leaf door 1 according to FIGS. 1a to 7 comprises a moving leaf 2 and a stationary leaf 3. The active leaf 2 and the fixed leaf 3 are mounted in a door frame 4, which is part of the adjoining the door leaf wall area. For storage, the door hinge 5 a is on the moving leaf 2 and the door hinge 5 b is present on the inactive leaf. The door hinges 5a and 5b are rotatable or pivotable about a stationary bearing axis of rotation L (wing 2) or L '(vertical leaf 3) and, of course, may also comprise a plurality of hinged connections between the respective door leaf 2 or 3 and the wall area adjacent thereto. The active leaf 2 and the fixed leaf 3 are both in the opening direction O ( Fig. 1 c) aufschwenkbar, that is, for example, in FIG. 1 a in the picture plane into, or in FIG. 1b out of the picture plane.

The active leaf 2 and the fixed leaf 3 each have a fold 6a (for example according to FIG Fig. 1 a) or 6b (for example according to Fig. 1b ), which partially overlaps the other wing in the closed state of the two-leaf door 1. The gangway-side fold 6a lies in the opening direction O in front of the inactive leaf 3 and the standing-wing-side fold 6b in the opening direction O behind the active leaf 2. This means that a certain closing sequence must be adhered to to close the opened double-leaf door 1, to the active leaf 2 and Also to be able to pivot the inactive leaf 3 in the respective closed position. This results, for example, particularly clearly from the top view FIG. 3b , In order to enable the two-leaf door 1 to be closed, it is therefore necessary for the inactive leaf 3 to reach its closed position in front of the active leaf 2 or for the active leaf 2 to be held in a fixed minimum opening position or at a defined opening angle α which is dimensioned such that the inactive leaf 3 on the leaf 2 can swing past into its closed position in order to prevent it from lying on the fold 6a of the (closed or almost closed) active leaf 2.

This allows a device for closing sequence control 7, comprising a blocking device 8, a triggering device 9 and arranged between the active leaf 2 and the wall frame formed by the door frame 4 door closer 10. The door closer 10 has a force acting on the active leaf 2 closing arm 11, wherein the Door closer 10 is formed in such a way that it acts on the closing arm 11 with a closing force in a known manner, which is transmitted to the active leaf 2 in such a way that it from an open position (for example according to the FIGS. 3a and 3b ) in a closed position (for example according to the FIGS. 1a to 1c ) is pressed. The closing arm 11 is pivotally connected to the door closer 10 at its one end region 12a about a door closer rotation axis T and is rotatably supported at its other end region 12b about a guide axis of rotation F, in the present embodiment concretely in a slider 16 guided linearly in a slide rail 15.

The bearing axis of rotation L, the door closer axis T and the guide axis F, which extend parallel to one another in their axial extension, are arranged in a specific relationship to one another in such a way that they are orthogonal in a projection plane E when the three axes of rotation are projected to the axial direction of the bearing axis of rotation L in such a way to each other that they form a toggle lever 13 together with the two intermediate areas B1 and B2 or are arranged in the form of a toggle lever 13. The position of the projection plane E relative to the bearing axis of rotation L is in Fig. 3a given by way of example, wherein the outer edges of the projection plane are by no means to be understood as the projection plane E towards their sides. The projection plane E is also located, for example, in FIG Fig. 4b respectively Fig. 4c parallel to the image plane. The FIGS. 4c and 5b (or with regard to further embodiments also the FIGS. 8b and 10d ) reflect the position of the three pivot points L, T and F as well as the Sperrhebelanlenkung in the projection plane E. The pivot points L, T and F (or the projection of the respective axes of rotation in the projection plane) are arranged in series, wherein the central pivot point (in Fig. 4b the pivot point of the door closer rotation axis T) in each case with the two outer pivot points (in Fig. 4b the pivot points of the bearing axis of rotation L and the guide axis of rotation F) is operatively connected via a lever arm. The lever arms of the toggle lever 13 are formed by lying between the pivot points L and T or T and F area B1 and B2. In the outline sketches of the FIGS. 4b and 5b the lever arms are shown as immediate lines of action. It goes without saying that these lines of action transmitted to the concrete construction can be represented by various components according to the invention. In relation to Figure 4c results, for example, that the area B2 is formed essentially solely by the closing arm 11. The area B1 or the line of action of the lever arm between the bearing axis of rotation L and the door closer rotation axis T, in contrast, partly comprises an area of the door closer 10 and of the door leaf of the active leaf 2. The in the FIGS. 4b and 5b (or with regard to further embodiments also the FIGS. 8b and 10d ) Schematic diagrams serve only to illustrate the formation of the toggle lever 13 and its articulation by a locking lever 17 further specified in particular. In particular, the areas B1 and B2 can be realized in other ways, for example, by embodiments that are not solid along the Connecting lines (corresponding B1 and B2) are formed. Rather, it is crucial that the individual pivot points or axes of rotation L, T and F are connected to each other in the manner indicated above, that the leverage forces acting between the individual pivot points can be transmitted. In addition, the arrangement of the guide axis of rotation F and the door closer axis of rotation can also be varied, depending on whether the door closer 10 is arranged on the tread side (as in the embodiments given in the figures and as is usually the case when using a slide rail door closer) or on the wall side ,

The concrete design of the blocking device 8 may also vary. In the concrete exemplary embodiments of the figures, the blocking device is a clamping device in which a pivotable clamping plate is arranged (not visible in detail in the figures), through which an adjusting rod 14 guided by the clamping device and running parallel to the slide rail 15 passes is.

The execution of the adjusting rod 14 is in particular in Fig. 7 specified. Accordingly, the adjusting rod 14 comprises a clamping region 18 guided partly by the blocking device 8 and an adjusting region 19 adjoining it in the direction of the active leaf 2. Both regions 18 and 19 are connected to one another via a connecting joint 20, the connecting joint 20 being a U-shaped receiving fork 21 includes the clamping portion 18, which surrounds the adjusting portion 19 in its tip region like a fork and a bolt plug connection with a mounting hole (in Fig. 7 not shown) in the clamping region 18 is connected thereto. At predetermined intervals, the adjustment region 18 has a plurality of mutually spaced similar joints on (Justierlöcher 22 and 22 '), which allow a width adjustment of the length of the adjusting rod 14 to the width of the respective double-leaf door., For this example, the factory ex works relatively long adjustment 19th the adjusting rod 14 (with, for example, more than two Justierlöchern 22 and 22 ') capped to the required length and then used in each case to the inactive leaf 3 outward Justierloch for the pin connector to the clamping portion 18 out. At the in Fig. 7 given embodiment, the connection to the receiving fork 21, however, always via the same mounting hole and the width adjustment of the adjusting rod 14 by a capping of the length to the moving leaf 2 out. For this purpose, the adjustment portion 19 of the adjusting rod 14 is also connected to its other end via a pin connector with the gangway side mechanism of the device for closing sequence control, specifically with a locking member 23 (in Fig. 7 only partially visible), which is articulated at its other end on the locking lever 17. However, this pin connector includes a carriage 24 through which the adjustment portion 19 is guided. The carriage 24 is rotatably connected to the locking member 23. The distance between the individual adjustment holes 22 and 22 '(and optionally other existing Justierlöcher) is chosen so that the thus compatible door widths are based on the standard widths of two-leaf doors.

The blocking device 8 makes it possible to determine the active leaf 2 at least in a minimum opening position in the door closing direction or opposite to the opening direction O. This minimum opening position is in the embodiment according to the FIGS. 1a-7 for example, at a door opening angle α = 30 °. The opening angle α results from the angle between the active leaf 2 and the door frame 4 in the plan view or also in the projection plane orthogonal to the bearing axis L. The blocking device 8 is formed in such a way that the active leaf in each beyond the minimum opening position with respect to the door opening angle position in an opening of the inactive leaf 2 via a fixed trigger point (in the present embodiment, this trigger point is already at a few degrees door opening) in his then just present door opening angle is detected. Alternatively, the device for closing sequence control is designed in such a way that the active leaf 2 is also aufdrückbar in tripped (ie blocking) blocking device 8 in the door opening direction O beyond the minimum opening position, but then by the door closer 10 exerted on the active leaf 2 door closing force up to the minimum opening position is pressed back again. Essential for the operation of the blocking device 8 is that the clamping device prevents longitudinal displacement of the adjusting rod 14 in the blocking state. This determination of the adjusting rod is transmitted according to the invention via the locking mechanism described in more detail below on the active leaf 2.

To explain the operation of the locking mechanism is particularly to the FIGS. 4a to 5c directed. The FIGS. 4a to 4c relate to a door leaf position in which the active leaf 2 is in its minimum opening position and the inactive leaf 3 is opened opposite to the same angle. At the door flight position according to the FIGS. 5a to 5c both door leaves 2 and 3 are open far beyond a door opening angle of 90 °. In both positions of the FIGS. 4a to 5c the active leaf 2 is determined in each case. The blocking mechanism responsible for this is essentially controlled by the blocking device 8. This is in operative engagement with the adjusting rod 14, as already described above. The adjusting rod 14 is guided longitudinally displaceable in the blocking device 8, wherein an activation of the blocking device 8 detects the adjusting rod 14 at least in the direction in which the adjusting rod 14 moves when closing the active leaf 2 along the blocking device 8 (in the FIGS. 5a and 6a for example, to the right). Non-sliding with the adjusting rod, the L-shaped end of the locking member 23 is connected via a plug-in pin connection. At the other end, the locking member 23 is articulated on the locking lever 17 via a hinge connection.

The locking lever 17 is formed with two arms, wherein the one arm 24 is connected to the locking member 23 and the other arm 25 to the locking arm. The two arms 24 and 25 are arranged in the pivoting plane of the locking lever 17 at an angle of approximately 135 ° to each other. The locking lever 17 is in a door frame on the front side of the slide rail 15 arranged locking lever bearing 26 or mounted on the wall side and pivotable about the locking lever bearing pivot axis S. The axis direction the axis of rotation S is parallel to the axial directions of the axes of rotation L, T and F. The other arm 25 of the locking lever 17 is longer than the one arm 24 of the locking lever 17 and the closing arm 11 of the gangway-side door closer 10 articulated.

The linkage comprises a slot 27 at the end of the other arm 25, in which a projecting on the closing arm 11 and projecting from this in the direction of the locking lever 17 guide pin 28 protrudes. The slot 27 thus provides a control slope along its inner edge for the guide pin 28 is available. The control slope is formed in such a way that the guide pin 28 moves at a closing movement of the active leaf at an angle to the course of the control slope. If the locking lever 17 is prevented by the blocking device 8 via the adjusting rod 14 and the locking member 23 at a pivoting at least in the door closing direction or against the door opening direction, acting as a guide element guide pin 28 abuts against the control slope and is characterized in a continuation of his from the Knee lever 13 between the fulcrums L, T and F caused movement in the direction he performs when closing the active leaf, prevented. The control slopes are part of the slot 27, on the flanks of the guide pin 28 is applied. Thus, the guide pin 28 can strike against the control slope in the longitudinal direction of the slot 27, they must be in the present embodiment with the Gleitschienentürschließer 10 at least at their relative position to each other in located in the minimum opening position scroll 2 tangentially in the closing direction of the guide pin 28 and in the direction of the control slope at an angle to each other , In contrast to the previous closing sequence controls, especially for sliding rail door closer, which provided a determination of the active leaf 2 via a fixation of the position of the slider 16 in the slide rail 15, the invention is the way via a slider 16 bridging locking mechanism with, inter alia, a locking lever 17, which is detectable via the blocking device 8 and is articulated on the closing arm 11 of the door closer 10. The outgoing of the blocking device 8 blocking force is thus transmitted in particular with the cooperation of the locking lever 17 on the toggle lever 13 and counteracts the door closer 10 outgoing in the door closing direction door closing force when the blocking device 8 is detected.

The FIGS. 4c and 5c illustrate the articulation of the locking lever 17 on the knee lever 13 from the perspective of the projection of the axes S, A, L, T and F in the axial direction in the projection plane E. The axes S, A, L, T and F are arranged in the manner that their extension of the axes S, A, L, T and F in the axial direction parallel to each other. By definition, all extensions thus meet orthogonally on the projection plane E. This particular arrangement also requires that the length of the two levers be between L and T and T and F over the entire opening and Closing process remains constant, whereas the length of the lever formed by the locking lever 17 between S and A changes due to the slot guide 27 over the pivoting process away. The guide element 28 thus slides over the pivoting process in a partial area along the control slope 32.

The central advantage of the embodiments of the device according to the invention for closing sequence control indicated in the exemplary embodiments of the figures is that the transmission of the blocking force no longer takes place via the slider 16 guided in the slide rail 15, but via the blocking lever 17. The blocking device 8 thus causes on the locking lever 17 comprehensive locking mechanism, the determination of the active leaf 2 (at least in its minimum opening position) with open (or over the trigger point away open) poppet 3. Die FIGS. 4c and 5c illustrate further that the locking lever 17 is hinged to the toggle lever between the two outer pivot points T and F in the projection plane E (this corresponds in the embodiment according to the FIGS. 1 to 7 the area B2). Thus, the blocking device does not act directly on the slider, but transmits the locking force on the locking lever 17 in the knee lever 13. The locking lever 17 thus deflects the locking mechanism at a location detached from the slider in the slide rail. Therefore, this device for closing sequence control is also ideal for use on the strip side, since in this way can be used particularly simple and elegant other points for articulation of the locking mechanism, which in relation to the opening movement of the active leaf 2 over the entire opening operation respectively relative to the plane of movement at least to move rectified in one direction and to move rectified in the opposite direction during a closing operation.

Rectified is to be understood that the movement over the entire opening or closing process alone takes place at least with respect to one direction in the projection plane E only in one direction. Of course, this preferably includes movement patterns in which the movement of the locking mechanism over the entire opening process (and vice versa also with respect to the closing operation) in all directions of movement (in particular in the projection plane E) is rectified. However, the invention also allows the articulation of the locking lever 17 at points on the toggle lever 13, which are rectified only with respect to a direction of movement in the projection plane E, but move in opposite directions in the other direction of movement in the projection plane on the opening or closing operation. It is essential that the articulation of the locking lever 17 takes place on the toggle lever 13 in such a way that the guide element or the guide pin 18 on a continuation of its movement when closing the active leaf 2 by a stop on the (detected) control slope (or the locking lever 17th ) is prevented or transmitted from the locking lever 17 Locking force obliquely applied to the toggle lever 13: In the blocking position (especially in the blocking position in the minimum opening position) meet the pivotal movement of the locking lever 17 and the articulation point on the toggle lever 13 to such oblique transfer of the blocking force ideally to each other so that the tangent to the closing movement of Guide element (ie, their movement when continuing the closing operation of the active leaf 2) and the control slope at the pivot point and preferably at an obtuse angle to each other.

To release the blocking of the active leaf 2 by the blocking device 8, the triggering device 9 is provided, the basic structure and its mode of action in the Figures 6a and 6b is shown in more detail. FIG. 6a is an enlarged detail of the dotted framed area FIG. 4a and FIG. 6b is a schematic diagram of the lever assembly FIG. 6a in the projection plane E (the dotted connecting lines indicate the position of the individual pivot points S ', A', L ', T', and F 'in the Figures 6a and 6b at). The triggering device 9 is designed in such a way that it activates the triggering device 9 as a function of the position of the inactive leaf 3.

In essence, the release mechanism on the side of the inactive leaf 3 compared to the locking mechanism of the active leaf side at least with respect to the components and the pivot points (S, A, L, T and F correspond functionally S ', A', L ', T' and F ') formed very similar. Thus, in particular a two-armed control pivot lever 17 'is present (area B1' and B2 'in analogy to the area B1 and B2), which is frontally mounted to the slide rail 15 on the inactive side (parallel to the projection plane E). The Steuerschwenkhebel 17 'is hinged on the one hand on the closing arm 11' of the door closer 10 'and at its other end with a transmission member 23' functionally coupled. The door closer 10 ', the pivot lever 17', the transmission member 23 'and the closing arm 11' are identical to the arrangement described above on the side of the active leaf 2. A reversed arrangement thus requires only a conversion of the arrangement of the blocking device 8, the triggering device 9 and The actual actuation of the triggering device 9 via a Umgriff 29 in the end of the transmission member 23 ', the triggering device 9 in the closing direction SR (corresponds to the direction of movement, in which the transmission member 23' when closing the inactive leaf 3 against the door opening direction O moved) and thus operated on train. In the actuated state of the triggering device 9, the blocking device 8 is unlocked and the adjusting rod or the locking mechanism in the unlocked state.

The special design of the release mechanism has a comparable effect with the special locking mechanism. Thus, it is possible with the trigger mechanism described in particular in the tape-opposing assembly to use over the entire opening and closing movement of the inactive blade 3 a rectified movement to control the triggering device, even if in particular the slider 16 'reverses its direction of movement at the end of the closing movement , Thus, in particular, the stationary leaf side includes a toggle lever arrangement, which is articulated by the control pivot lever 17 'in the manner of the locking lever 17 described above.

An alternative embodiment of the device for closing sequence control is in the FIGS. 8a to 9b shown, wherein both the inactive leaf and the active leaf 2 are shown in different open positions. The essential difference of this embodiment to the previous embodiment is that the possibility of blocking the active leaf 2 is not possible for each opening angle of the active leaf 2, but only from a door opening angle of> 0 ° to about 40 °. For beyond door opening angles a test position of the active leaf 2 in these positions is not possible. If the active leaf 2 is activated with blocking device 8 in a door opening angle greater than approximately 40 °, it is pushed back by the door closer 10 in the direction of its closed position up to a door opening angle of approximately 40 ° or the maximum possible locking angle.

These special control properties of this embodiment are essentially due to the particular configuration of the locking lever 30, which unlike the locking lever 30 has no oblong hole closed on all sides of the pivoting plane, but rather a slot "open" to a side in the pivoting plane with corresponding control slope 32a , Due to the design as "open slot" the control slope 32a is part of a substantially fork-shaped locking lever 30, comprising a base body and two arranged thereon elongated and mutually parallel tines. The control slope runs essentially on the slide rail 15 facing inside of the front in the closing direction of the locking lever 30 prong. This embodiment of the control slope allows the guided at least in the range of the door opening angle of 0 to about 40 ° guide member 31 (in this embodiment, a coaxial with the Türschließerrrehachse T between the locking arm 11 and the door closer 10 arranged guide ring) only in this area against the control slope abuts and thus is guided by this or can be blocked via the locking mechanism. At beyond door opening angles, the guide member 31 is disengaged from the control slope 32a. This happens at a defined opening angle, since the pivoting of the locking lever 30 is angularly limited in the door opening direction by a corresponding stop (not shown in the figures). In addition, a spring loading is also present, which urges the locking lever 30 in its maximum opening position and in the direction of the stop. Therefore, as long as the locking lever 30 is not engaged with the guide member 31, the locking lever 30 assumes a defined position. This position is referred to as a "catching position", since a minimum requirement of this defined position is that it is suitable for catching the guide element 30 of the closing active leaf 2 in order to ensure engagement in the control slope. Ideally, the spring force of this spring action is chosen relatively weak to oppose the closing active leaf only a weak opposing force. Finally, the control of the open position of the active leaf is to take place almost exclusively via the locking mechanism, the basic mode of operation of which has already been explained above.

Compared to the previous embodiment, the concrete articulation of the toggle lever 13 is varied by the locking lever 30. In contrast to the previous embodiment, the locking lever 30 is not articulated here in the region of the toggle lever 13 between the pivot point in the projection plane E of the door closer rotation axis T and the guide axis F arm knee lever, but contacted this directly at the pivot point of the door closer rotation axis T on there coaxial with the door closer rotation axis T. arranged annular guide element 31. The corresponding arrangement of the toggle lever 13 and the locking lever 30 in the projection plane E are in Fig. 8c specified. The dotted lines indicate (as with the FIGS. 5c and 6b ), the corresponding projection of the relevant axes of rotation S, A, L, T and F schematically, wherein the superposed in the projection plane fulcrums of the axes of rotation A and T are indicated only with a common dotted line.

Another peculiarity of this embodiment is that the trigger mechanism of the inactive leaf side, in contrast to the previous embodiment, is equipped with a pivoting lever 30 ', which for control purposes, in contrast to the previous embodiment, also has an oblong hole open to one side with a corresponding control slope for engagement with a mounted on the door closer rotation axis of the door-side door closer guide element (in the basic structure, the control mechanism corresponds to the articulation of the blocking device 8 and the triggering device 9, the structure of the control mechanism on the active leaf side). Furthermore, the pivot lever 30 'is spring-loaded and strikes against a stop at a defined opening angle. On the one hand, this arrangement has the consequence that, even in this embodiment, without major conversion measures can be changed between a right-side and a left-side mounting or replacement of aisle and inactive leaf, since the control mechanism itself is the same on both sides and only the antenna of the blocking device 8 and the triggering device 9 must be adjusted. On the other hand, the opening angle of the inactive leaf 2 is not detected over the entire pivoting range of the inactive leaf 3 of the stand-wing-side release mechanism, but only in the range of door openers of the inactive leaf of less than 40 ° or from the respective door opening angle, the collecting position of the inactive leaf. 3 equivalent. This door opening angle is expediently chosen such that the determination of the active leaf is ensured when the inactive leaf 3 has to swing past for closing the two-leaf door on the moving leaf 2.

The FIGS. 10a to 10e Finally, in a similar embodiment to the previous embodiment, the locking lever 33 does not deflect the toggle lever 13 over the entire pivoting range of the active leaf 2, but only from door opening angles of approximately 40 ° and smaller In this exemplary embodiment, the active leaf 2 is thus captured by the blocking lever 33 when it is closed at a certain door opening angle Another special feature of this exemplary embodiment is that the blocking lever 33 has a hook 34, against which the active leaf 2 in a receiving element 35 between two horizontally lying The control bevel 36 is thus integrated into the hook 34 here.

The receiving element 35 is arranged on the door leaf of the active leaf 2 on the side of the door closer 10. Thus, this embodiment is further characterized by the fact that the articulation of the toggle lever 13, in particular from the projection view in Fig. 10d shows the toggle articulated between the formed by the door closer rotation axis T and the bearing axis of rotation L in the projection plane E fulcrums. In addition, the linkage is not directly on the lines of action symbolized by the connecting lines between L and T and T and F, but in a region of the door leaf, which is not on the line of action in the projection plane E. This area is substantially formed by the door leaf, so that in this embodiment, the locking lever 33 indirectly articulates the knee lever 13 obtained in the projection plane via a fixedly connected to the toggle 13 area.

Another essential feature of this embodiment lies in the special storage of the locking lever 33. This is in the region of the locking lever pivot axis S in the slide rail 15 mounted on a slider 37, in which also the slider 16 is guided. The blocking device 8 is designed in such a way that it is operatively connected to the slider (37) by means of a locking rod (not visible) adjoining the adjusting rod 14, which is likewise guided in the slide rail 15, and in this way the blocking function of the Locking lever 33 controls.

As in the previous embodiment, the trigger mechanism on the inactive side is identical and reversed arranged except for the concrete linkage to the blocking device 8 and the release device 9, so that here too a quick change from the right-side mounting on the left-side mounting is possible.

For both "catching" embodiments according to the FIGS. 8a to 10e It is also true that the stop for the locking lever 30 and 33 is adjustable, so that hereby a vote of the door opening angle in the collection position to the respective installation conditions is possible.
