Abstract

The invention relates to a device for regulating the sequence in which a double door comprising an active door leaf and a passive door leaf is closed, both door leaves being connected, by means of a door strip, to a wall area adjoining the same so as to be pivotable about a stationary axis of rotation of a bearing. Said device comprises a blocking mechanism that allows the active door leaf to be blocked in a minimal open position in the door-closing direction, a triggering mechanism that is controlled by the passive door leaf and releases the blocking mechanism in a predefined position of the passive door leaf, and a door-closing mechanism that is arranged between the active door leaf and the wall area, has a closing arm acting on the active door leaf, and applies a closing force to the closing arm. The closing arm is hinged to the door-closing mechanism in the first end region so as to be rotatable about an axis of rotation of the door-closing mechanism, while being mounted in the second end region so as to be rotatable about a guiding axis of rotation. When projected onto the plane extending perpendicular to the axial direction of the axis of rotation of the bearing, the axis of rotation of the bearing, the axis of rotation of the door-closing mechanism, and the guiding axis of rotation are arranged so as to jointly form a bent lever along with the two intermediate zones, wherein the axis of rotation of the bearing is the fulcrum of said bent lever, and the axis of rotation of the door-closing mechanism and the guiding axis form the other pivots of the bent lever.

Description

DEVICE FOR THE SCHUEBFOLCERECELUNC

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

Two-leaf doors are often used in passage areas, which 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 each have a fold to allow, inter alia, a particularly tight closing 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. Rather, the active leaf must be open in a certain minimum opening angle, so that the inactive leaf can be swiveled past with its fold on the active leaf and its fold. A generic device for closing sequence control now ensures that the opened passive leaf in front of the active leaf has its own closed position can take. Thus, depending on the position of the inactive leaf, the closing sequence control keeps the active leaf in the minimum opening position until the inactive leaf is pivoted past the curved leaf, in particular into its closed position, in order to ensure the sequence of both door leaves required for closing the door.

The pivoting of the two leaves is made possible in each case via an outside 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.

Cattungsgemäße devices for closing sequence control include a blocking device with which the Cang wing 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 on the partially open aisle can still swing past. 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 region 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. Both the door leaf side and the wall side mounting of the door closer is possible. If a sliding rail door closer is used with a slide rail, as will be described in more detail below, the slide rail is usually on the wall side and the door closer is arranged on the 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 rotatably mounted on the door closer and rotatably mounted at its second end region about an axis of rotation, hereinafter also called guide axis of rotation. 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 axis of rotation, the door closer axis of rotation and the guide axis of rotation are arranged in a projection in the plane orthogonal to the axial direction of the bearing axis of rotation in series and further in such a way that together with the two intermediate areas together form a toggle whose stationary pivot point the Bearing axis is and its other 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 special positioning results from the projection of the three axes of rotation in the axial direction, ie their extension in the direction of their each axis forming the axis of rotation. The projection takes place in a plane which is orthogonal to the axial direction of the bearing axis of rotation, that is usually arranged horizontally. 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 are not necessarily 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 Cang wing 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 Cangwing 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 Türschließerdrehachse) are arranged in the projection plane in series with the pivot point of the bearing axis of rotation, 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 with the pivot point of the bearing axis of rotation functionally connected is and lies in the middle of the array. 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 point (corresponding to the "knee" in the toggle lever) between the pivot points of the guide axis of rotation and the bearing axis of rotation. so that the pivot point of the guide axis of rotation between the two pivot points of the bearing axis of rotation and the door closer rotation axis is arranged (here thus forms the pivot point of the guide axis of rotation "knee").

The invention also includes the use of door closers, in which the locking arm is more and more particularly two-part design, as is the case for example in the so-called scissors linkage or Gelenkarmtürschließern. However, sliding rail door closers are preferred in which the locking arm is articulated on the guide axis of rotation on a slider which is mounted linearly displaceable 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 mutually about the arranged in the projection plane between the two outer pivot points central pivot relative to each other pivotable lever arms of the toggle lever are formed by the areas lying between the central pivot point and the respective outer pivot points in the projection plane or these pivot points with each other connect physically. 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 specific physical design may vary at the double-leaf door. So those with a lever arm in functional Connecting pivot points or axes are not structurally related to each other along the direct connection / line of action. 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 double-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, 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 in so-called sliding 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 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 during 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 in particular at the door hinge side Mounting the case is. This leads to the fact that the minimum opening position must be selected with a comparatively large door opening angle, especially when using sliding rail door closers mounted opposite the door hinge, in order to reliably detect the closing movement of the active leaf 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 rail door openers. 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 door hinge side mounting, although a door hinge side mounting is possible. In addition, such a blocking device can be combined with a locking lever arranged according to the invention, together with slide rail door closers and also with scissor linkage or Gelenkarmtürschließern.

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 Knee lever and the locking lever in the desired locking position, in particular the Mindestöff- nungsstellung, and the line of action of the locking lever in the projection plane obliquely, ideally perpendicular to each other. In particular, the slide rail door closer is to be noted in this connection that the articulation by the blocking lever in the projection plane furthermore preferably takes place at an angle to the displacement path 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 wording "between the two outer pivots." The essential effect of the invention when using a slide rail door opener is the result that distance from the previous one by acting on the slide guided in the slide rail has been eliminated and instead a diversion of the Movement of the toggle lever and in particular of the closing arm is achieved via the additional locking lever, which as a result, ideally an 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 Blocking force decisive part on which the blocking device can begin, 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 allows 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 tune the braking behavior of the blocking device, in particular in the range 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 process in one direction, as for example in the band mutual Installation of a Gleitschienentüröffners the case. 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 preferably oblique to the 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 particularly evident particularly 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 storage of the locking lever on the wall area is particularly in view of the required installation work beneficial. 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.

In principle, the locking lever can deflect the toggle lever between its two outer pivot points in the projection plane. Preferably, however, the locking lever 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 gear, 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 specific 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 can of course also be multi-part, which for example facilitates the adaptation possibilities 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 a front side 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 specific design of the compound of the locking lever with the toggle lever, generally referred to above as articulation, can be realized in different ways and ways. In principle, overlapping and overlap-free connection possibilities are included within the scope of the invention. It is preferred for articulation of the locking lever on the toggle lever a control slope exists 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 in 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 against 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 direction of opening of the active leaf" is basically to be understood as indicating the movement which the locking lever performs when the active leaf is opened, which in no way means that this movement takes place parallel to the opening movement of the door leaf. This depends rather on the specific arrangement from (the same also applies to the rest of 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 at an opening of the active leaf. 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, in particular with regard to the opening angle of the locking lever stop, adjustable locking lever stop has been found to be particularly advantageous. An adjustable locking lever stop allows the device of Closing sequence control to the individual circumstances particularly easy to adapt. 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 Sperrhebella- gergerdrehachse 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 foregoing, it can be seen 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-sided mounting since the slider reverses its direction of movement in the slide rail towards the end of the closing movement. 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 both the slider of the locking arm and, if present, the slider of the locking lever leads. 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 which is structurally formed in the projection plane from 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 bounded by the toggle 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 found that the concept of the locking lever in relation to the active leaf can be transferred in an advantageous manner 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 passive 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 actuate the triggering device in response to a fixed position of the inactive leaf. 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 pivoting control lever and the triggering device is further arranged for actuating the triggering device, which is designed in such a way that it actuates the triggering device to train. The integration of a pull rod instead of the previously used push rods is advantageous in that the material load of the control Gestänges is thereby significantly reduced and so, for example, bending or similar damage, in particular a buckling of the rod, which could lead to erroneous functional sequences, can be avoided in advance. 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 may be formed in the usual manner. 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 lever hinged on the locking member, 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, an adjusting rod is provided, which allows a length adjustment of the locking member or the connection between the locking lever and the blocking device. 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 division, 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, on the sole length adjustment, the entire device for closing sequence control to the respective door width is customizable. In terms of production technology, it is advantageous if the tie rod, at least in their articulation areas and in particular in its entirety identical to the locking member, in particular the locking bar is formed. 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 connect the blocking device and the triggering device directly to each other mechanically. 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, Bowden 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 Figures 1 a to 7 comprises a leaf 2 and a stationary leaf 3. The leaf 2 and the inactive 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 (active leaf 2) or L '(stationary leaf 3) and can of course also comprise a plurality of hinged connections between the respective door leaf 2 or 3 and the adjoining wall region. The active leaf 2 and the fixed leaf 3 are both swivelable in the opening direction O (FIG. 1 c), that is, for example, in FIG. 1 a into the image plane or in FIG. 1 b out of the image plane.

The active leaf 2 and the inactive leaf 3 each have a fold 6a (for example according to FIG. 1 a) or 6b (for example according to FIG. 1 b), which partially overlaps the other wing in the closed state of the double-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 is evident, for example, particularly clearly from the plan view according to FIG. 3b. To close the double-leaf To enable door 1, it is therefore necessary that the inactive leaf 3 reaches the closed position in front of the active leaf 2 or the active leaf 2 is held in a fixed minimum opening position or at a fixed opening angle α, which is dimensioned such that the inactive leaf 3 on the moving leaf 2 can swing past in its closed position to prevent contact of the inactive leaf 3 on the fold 6a of the (closed or almost closed) active leaf 2.

This allows a device for final order regulation 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 in that the door closer 10 is designed 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 is moved from an open position (for example according to FIGS. 3a and 3b ) is pressed into a closed position (for example according to FIGS. 1 a to 1 c). 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.

In their axial extension parallel to each other bearing rotation axis L, the door closer axis T and the guide axis F are arranged in a certain ratio to each other in such a way that they are in a projection of the three axes of rotation in a projection plane E orthogonal to the axial direction of the bearing axis L in the way to each other that they form together with the two intermediate areas B1 and B2 a toggle 13 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 given by way of example in FIG. 3a, wherein the outer edges of the projection plane are by no means to be understood conclusively as the projection plane E towards their sides. The projection plane E is also located, for example, in FIG. 4b or FIG. 4c, parallel to the image plane. Figures 4c and 5b (or with regard to further embodiments also the figures 8b and 10d) indicate the position of the three pivot points L, T and F and the Sperrhebelanlenkung in the projection plane E again. The pivot points L, T and F (or the projection of the respective axes of rotation in the projection plane) are arranged in series, the central pivot point (in FIG. 4b the pivot point of the door closer rotational 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 characterized by the between the Fulcrum L and T or T and F lying area B1 and B2 formed. In the schematic diagrams of Figures 4b and 5b, the lever arms are shown as immediate lines of action. It goes without saying that these lines of action transferred to the specific construction can be represented according to the invention by different components. With reference to FIG. 4 c, it results, for example, that the region B 2 is formed essentially solely by the closing arm 11. On the other hand, 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 partly comprises an area of the door closer 10 and of the door leaf of the active leaf 2. The figures in FIGS. 4b and 5b (or with respect to further exemplary embodiments also FIGS 8b and 1 Od) are merely illustrative of the design of the toggle lever 13 and its articulation by a locking lever 17 to be described in more detail below. In particular, the areas B1 and B2 can also be realized in other ways, for example also by embodiments which 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 rotational axis can also be varied, depending on whether the door closer 10 on the wing side (as in the embodiments given in the figures and as is usually the case when using a slide rail door closer) or wall side is arranged.

The specific 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 design of the adjusting rod 14 is specified in particular in Fig. 7 in more detail. Accordingly, the adjusting rod 14 comprises a clamping region 18, which is partially felt 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 comprises at the clamping portion 18, which surrounds the adjusting portion 19 in its tip region like a fork and a pin connector with a mounting hole (not shown in Fig. 7) in the clamping region 18 is connected thereto. At predetermined intervals, the adjustment region 18 has a plurality of mutually spaced similar connection points on (Justierlöcher 22 and 22 '), which is a width adjustment of Allow length of the adjusting rod 14 to the width of the respective double-leaf door. For this purpose, for example, from the factory relatively long adjustment range 19 of the adjusting rod 14 (with, for example, more than two Justierlöchern 22 and 22 ') capped to the required length and then each used to the inactive leaf 3 outward Justierloch for the pin connector to the clamping portion 18 out. In the embodiment shown in Fig. 7, the connection to the receiving fork 21, however, always via the same mounting hole and the width adjustment of the adjusting rod 14 by capping the length to the moving leaf 2 out. For this purpose, the adjusting 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 closing sequence control device, specifically with a locking member 23 (in Fig. 7 only partially visible), which at its other end on the locking lever. 1 7 is articulated. 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 rear wing 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 Figures 1 a - 7, for example, at a door opening angle α = 30 °. The opening angle α results from the angle between the Cangflügel 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 Cang wing in each above the minimum opening position with respect to the door opening angle outgoing position in an opening of the passive leaf 2 over a fixed trigger point (in the present embodiment, this trigger point is already at a few degrees door opening) is determined in his then present door opening angle. Alternatively, the device is designed for closing sequence control in such a way that the Cangflügel 2 even when triggered (ie blocking) blocking device 8 in the door opening direction O beyond the minimum opening position is further aufdrückbar, but then by the force exerted by the door closer 10 on the active leaf 2 door closing force 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, reference is made in particular to the figures 4a to 5c. FIGS. 4a to 4c relate to a door leaf position in which the active leaf 2 is in its minimum opening position and the fixed leaf 3 is opened at the same angle opposite one another. In the door leaf position according to FIGS. 5a to 5c, both door leaves 2 and 3 are opened far beyond a door opening angle of 90 °. In both positions of the figures 4a to 5c, the Cangwing 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 figures 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 1 7 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 with the locking lever. The two arms 24 and 25 are arranged in the pivoting plane of the locking lever 1 3 at an angle of approximately 1 35 ° to each other. The locking lever 1 7 is mounted in a frame on the front side of the slide rail 1 5 arranged locking lever bearing 26 door frame or wall side and pivotable about the locking lever bearing pivot axis S. The axial direction of 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 1 7 is longer than the one arm 24 of the locking lever 1 7 and the closing arm 11 of the gangway-side door closer 10 articulated.

The articulation comprises a slot 27 at the end of the other arm 25, in which a protruding on the closing arm 1 1 and protrudes from this in the direction of the locking lever 1 7 projecting guide pin 28. 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 1 7 prevented accordingly 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 the knee lever 13 between the pivot points L, T and F caused movement in the direction he performs when closing the active leaf, prevented. The control slopes are part of the Long hole 27, on the flanks of the guide pin 28 abuts. Thus, the guide pin 28 may 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 at located in the minimum opening position Cangflügel 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 can be detected via the blocking device 8 and is articulated on the closing arm 1 1 of the door closer 10. The outgoing from 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 10 is detected.

Figures 4c and 5c illustrate the articulation of the locking lever 17 on the toggle 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 such a way that their extension of the axes S, A, L, T and F in the axial direction parallel to each other. All extensions thus meet by definition orthogonal to the projection plane E. This particular arrangement also requires that the length of the two levers between L and T and T and F remains constant throughout the entire opening and closing process, whereas the length of the locking lever 17 formed lever between S and A due to the slot guide 27 changes 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 invention shown in the embodiments of the closing sequence control is that the transfer of the blocking force is no longer done via the guided in the slide rail 15 16, but via the locking lever 1 7. The blocking device 8 thus causes via the locking lever 1 7 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) fixed leaf 3. Figures 4c and 5c illustrate further that the locking lever 7 is articulated on the toggle lever between the two outer pivot points T and F in the projection plane E (this corresponds to the area B2 in the exemplary embodiment according to FIGS. 1 to 7). Thus, the blocking device does not act directly on the slider, but transmits the blocking force on the locking lever 17 in the Knee lever 13. The locking lever 1 7 thus deflects the locking mechanism at a location detached from the Cleiterposition 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 Öffnungsbzw. 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 1 7 at points on the toggle lever 1 3, 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 1 7 takes place at the toggle lever 1 3 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 hitting the (detected) control slope (or the Lock lever 1 7) is prevented or transmitted from the locking lever 1 7 locking force is applied obliquely to the toggle lever 13. In the blocking position (especially in the blocking position in the minimum opening position), the pivotal movement of the locking lever 1 7 and the articulation point on the toggle lever 1 3 to such oblique transfer of blocking power ideally meet one another so that the tangent to the closing movement of the guide element (ie their movement when continuing the closing operation of the active leaf 2) and the control slope at the articulation point obliquely 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 a partial enlargement of the dotted framed area of FIG. 4a, and FIG. 6b is a schematic diagram of the lever arrangement from FIG. 6a in the projection plane E (the dotted connecting lines against the position of the individual pivot points S ', A', L ¹ , T '). , and F 'in Figures 6a and 6b). 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 the essential features, 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 functionally correspond to S ¹ , A, L ', T' and F ') are very similar. Thus, in particular a two-armed control pivot lever 17 'is present (range BT and B2' in analogy to the range B1 and B2), which is frontally mounted to the slide rail 15 on the inactive side (parallel to the projection plane E). The Steuerschwenkhebel 1 7 '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 1 1' are identical to the above-described arrangement on the side of the active leaf 2. A reversed arrangement thus requires only a reaction of the arrangement of the blocking device 8, the triggering device. 9 and the Justierstange 14. The actual operation 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 moves) and thus pressed 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 release mechanism described in particular in the tape-opposing mounting 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 inactive leaf side comprises a toggle lever arrangement, which is articulated by the control pivot lever 1 7 'in the manner of the locking lever 17 described above.

An alternative embodiment of the device for closing sequence control is shown in Figures 8a to 9b, wherein both the inactive leaf 3 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 °. With beyond door opening angles a determination of the active leaf 2 in these positions is not possible. If the active leaf 2 is activated when the blocking device 8 is in a door opening angle of greater than approximately 40 °, it will rather be moved by the door closer 10 into Direction of its closed position pushed back up to a door opening angle of about 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 1 7 has no closed on all sides of the pivot plane slot, but rather a "open" to one side in the pivoting plane slot By the design as "open slot" the control slope 32a is part of a substantially fork-shaped locking lever 20, 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 1 1 and the door closer 10 arranged guide ring) only in this area strikes against the control slope 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 is done at a defined opening angle, since the pivoting of the locking lever 30 by a corresponding stop (not shown in the figures) is angularly limited in the door opening direction. 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 30, the locking lever 30 assumes a defined position. This position is referred to as a "catching position" because a minimum requirement of this defined position is that it is capable of catching the guide element 30 of the closing active leaf 30 to ensure engagement with the control ramp Finally, control of the open position of the active leaf is to be effected almost exclusively via the blocking 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 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 on the toggle attached. directs, but contacted this directly at the pivot point of the door closer rotation axis T via the there coaxial with the door closer rotation axis T arranged annular guide member 31st The corresponding arrangement of the toggle lever 1 3 and the locking lever 30 in the projection plane E are shown in more detail in Fig. 8c. The dotted lines indicate (as in FIGS. 5c and 6b) the corresponding projection of the relevant axes of rotation S, A, L, T and F schematically, the rotational points of the axes of rotation A and T lying on one another in the projection plane having only one joint dotted line are indicated.

Another peculiarity of this embodiment lies in the fact that the trigger mechanism of the inactive leaf side, unlike the previous embodiment, is equipped with a pivoting lever 30 ', which for control purposes, in contrast to the previous embodiment also a slot open to one side with a corresponding control slope has, for engagement with a mounted on the door closer rotational axis of the standflügelseiti- door closer door guide member (in the basic structure corresponds to the control mechanism except for 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. This arrangement has the one hand with the result that even in this embodiment can be changed without major modifications between a right-side and a left-side mounting or replacement of aisle and inactive leaf, since the control mechanism is the same on both sides and only the articulation of Blocking device 8 and the triggering device 9 each 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.

Finally, FIGS. 10a to 10e show a third embodiment 1 "of the invention. Comparable with the previous embodiment, the blocking lever 33 does not deflect the toggle lever 1 3 over the entire pivoting range of the active leaf 2, but only from door opening angles 40 ° and smaller.Also in this embodiment, the active leaf 2 is thus captured when closing from a certain door opening angle of the locking lever 33. Another special feature of this embodiment is that the Locking lever 33 has a hook 34 against which abuts the Cangflügel 2 in a receiving element 35 between two horizontally disposed legs mounted bolt-like guide member 34 upon reaching the collection position. The control slope 36 is thus integrated into the hook 34 here.

The receiving element 34 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, as can be seen in particular from the projection view in Fig. 10d, articulates the toggle lever between the pivot points formed by the door closer rotation axis T and the bearing axis L in the projection plane. Moreover, the linkage does not take place 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 36 is essentially formed by the door leaf, so that in this embodiment, the locking lever 31 indirectly articulates the knee lever 13 obtained in the projection plane via a fixedly connected to the toggle 13 range 36.

Another essential feature of this embodiment is the special storage of the locking lever 36. This is stored in the region of the locking lever pivot axis S in the slide rail 15 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 is on the side of the wing except for the specific articulation of the blocking device 8 and the release device 9 identical and arranged laterally reversed, so that also allows a quick change from the right-side mounting on the left-side mounting becomes.

For both "catching" embodiments according to the figures 8a to 10e further applies 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.
