Description

The The invention relates to a device for closing sequence control of a double-winged Door with a moving leaf and a still wing, with both doors each with a door adjacent to the door Wall area, in particular a door frame, to a fixed Bearing pivot axis are pivotally connected.

Two-leaf doors will be often used in passage areas that only temporarily high transmission frequencies exhibit. Basically different one with two-winged one Doors the aisle of the passive wing. The active leaf is the one door wing that Normally used for inspection purposes, etc. The fixed wing, however, becomes often only in special cases open, if increased access, such as in an emergency for evacuation purposes or for carrying wide objects, etc., is required. simultaneously but for example, for fire protection reasons, um to counteract, among other things, the spread of smoke in an emergency the falling of a two-winged one Door desired. Two-leaf doors are therefore especially common Fire doors.

Both wing usually have at their side edges facing each other in each case a fold on, inter alia, a particularly dense closing the mullioned close the door enable. Of the Fold of the active wing is on the opening direction facing door leaf side arranged and overlapped when closed, the inactive leaf. The fold on the passive leaf is on the other hand, on the door closing direction facing door leaf side of the passive leaf arranged and overlapped the active leaf. However, the fold requires that the inactive leaf is not independent of the position of the active leaf is open or can be closed. The active leaf must rather in one certain minimum opening angle open be, so that the passive leaf with its fold on the moving wing and its fold can be pivoted past. A generic device for closing sequence regulation Now make sure that the open one Fixed leaf in front of the active wing can take his ge closed position. The closing sequence regulation holds thus in dependence of the position of the passive leaf the active leaf in the minimum opening position at least until the inactive leaf passes the aisle, especially in its closed position, is pivoted to the door lock required To ensure order of both leaves.

The Pivoting the two door leaves is each over an outboard hinge allows. The doors are to each on the adjacent wall area, in particular door frame, by means of the door hinge pivoted. Around the axis of rotation formed by the door hinge, hereinafter referred to as bearing axis, the door is pivotable.

Generic devices for closing sequence regulation comprise a blocking device, with which the active leaf in the Minimum opening position in door closing direction can be determined, wherein the minimum opening position of the active leaf, at least so chosen will that the inactive leaf at the partially opened leaf can still swing past. Furthermore, one is controlled by the passive leaf triggering device provided, which the blocking device at a predetermined Position of the passive leaf solves. The predetermined position of the inactive leaf, in the triggering device triggers off, is expediently chosen so that the active leaf is not more on the passive leaf can swing past. It is ideal when the passive leaf the triggering device in the closed state triggers.

A generic device for closing sequence regulation a double-winged Door includes also one between the active leaf and the door area arranged door closer with a force acting on the active leaf Closing arm. The locking arm thus connects the wall area with the door leaf or the door leaf. It is both the door leaf side as well as the wall-side mounting of the door closer possible. If a sliding rail door closer with a slide used, as described in more detail below is, the slide is usually on the wall side and the door closer on the door leaf side arranged. The door closer is charged the locking arm with a closing force, So a force over the locking arm in a closing movement of the active wing is implemented. 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 an axis of rotation, hereinafter also guide axis of rotation called, rotatably mounted. In the door closer is usually a compression spring or the like is present over which generates the closing force and the rotational movement of the locking 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 results this special positioning from the projection of the three axes of rotation in the axial direction, ie their extension in the direction of their respective axes 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 is the active wing hinged to the wall area adjacent to the active leaf. Under this Wall area is to be understood as a whole the area, the fixed to the active wing at least from the door hinge side adjacent. Under the wall area falls accordingly beside, for example a concrete wall also the usual existing door frames. The wall area is also not limited in size to understand. So the wall area can also by a corresponding post etc. be formed. Relative to the usually stationary Wall area are the aisle wing and the passive wing pivotable. The formed in the projection plane of the bearing axis Fulcrum is therefore not movable in this plane and thus formed stationary.

The further two pivot points (formed by the guide axis of rotation and the door closer axis of rotation) are in the projection plane in series to the pivot point of the bearing axis arranged either with the pivot point of the door closer rotation axis or alternatively the fulcrum of the guide axis in the projection plane with the pivot point of the bearing axis of rotation functional is connected and located in the middle of the array. The chronological order is determined essentially by the arrangement type of Door closer and the corresponding articulation of the locking arm. Is the door closer, for example on the door leaf arranged, as it is in particular when using a Gleitschienentürschließers the Case is, the bearing axis of rotation is effective or functionally substantially above the intervening area of the door leaf with the door closer rotation axis connected. At the door leaf side Arrangement of the door closer forms the pivot point of the door closer rotary axis thus the between the pivot points of the guide axis of rotation and the bearing axis of rotation lying pivot point (corresponding to the "knee" in the knee lever). Is the door closer against arranged on the wall side, the locking arm is articulated via its guide axis of rotation on the door leaf, so that the fulcrum 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 fulcrum of the guide axis of rotation the knee").

The The invention also includes the use of door closers in which the locking arm is multi-and is formed in particular two-membered, as for example in the so-called scissors linkages or Gelenkarmtürschließern the Case is. However, sliding rail door closer are preferred in which the locking arm on the Guide rotation axis is hinged to a slider, the linearly displaceable in one guide rail is stored. When Gleitschienentürschließer are both the fulcrum the guide axis of rotation and the pivot point of the door closer rotation axis not stationary. In contrast, in the scissor linkage or Articulated arm door closers too the pivot point of the bearing axis of rotation at the other end of the toggle lever in the projection plane opposite Fulcrum, either from the door closer rotation axis or the guide rotation axis is formed, 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 specific physical design may vary at 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, it is decisive the presence of such a Hebelarmverbindung that allows a corresponding power transmission via 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 includes, for example, when the door closer is arranged 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.

The From the prior art previously known devices for closing sequence control of double-winged Show doors however, several disadvantages. On the one hand, they condition that to the locking arm in terms of stability and resilience special demands are made because both the leadership of the active leaf as well as the blocking of the active wing in its minimum opening position alone over the locking arm is reachable. About that In addition, previously known devices are suitable for closing sequence control a double-winged Door, whole especially when using Gleitschienentürschließern, often not in the same way for the door hinge side and for the door hinge mutual Assembly. In the Türbandgegenseitigen Mounting swings the active leaf for example, the door closer and the, if present, slide rail opposite side of the active leaf. The door hinge and the door closer are in this arrangement variant thus on opposite each other Sides of the door leaf of the active wing appropriate. When mounting the hinge, the door closer and the door hinge both arranged from the same side of the door leaf. especially in the Türbandgegenseitigen Assembly in which the door hinge and thus the bearing axis of rotation, or in the projection of the Bearing pivot axis formed pivot point on the opposite door leaf side lies as the through the door closer rotation axis formed pivot point results in particular in so-called Gleitschienentürschließern a Transmission-related hyperextension of the toggle lever when closing or open of the active wing, whereby the slider guided in the slide rail after driving through the maximum stretched position at an opening angle of, depending on Type, usually about 20 ° to 30 ° his Direction of movement in the slide reverses.

The previously known blocking devices of such Gleitschienentürschließer act usually over a blockage of the slider or sliding block in the slide. This possibility device, however to its limits, when the movement of the slider in the slide rail during a closing movement the door not linear or alone in one direction when closing and only in the opposite direction when opening runs, as for example, in particular at the door hinge side Mounting the case is. this leads to in addition to that, especially when using hinged on each other Slide rail door closer the Minimum opening position at a comparatively large Door opening angle to get voted needs to be reliable the closing movement of the Active wing over the Be able to detect gliding movement. However, this adversely affects the reliability of the closed-loop control. The invention is also intended to solve this problem.

The solution The object is achieved in that the blocking device via a Lock lever on the toggle between its in the projection plane both outer pivots is hinged and the locking lever for transmitting a blocking force is formed by the blocking device on the knee lever. One The central aspect of the invention thus lies first in that the blocking device on the locking arm between its two outer pivots, So in the range of the lever arms and the center pivot, articulated is, and for example, no longer on the usual with Gleitschienentüröffnern end hinged glider acts. This includes the blocking device a separate and, in particular in the projection plane, pivotable Locking lever, the blocking effect exerted by the blocking device or locking force on the toggle and thus ultimately on the Door leaf transmits. For transmission 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 wing, So in at least one direction. This will be a particularly versatile get usable device for closing sequence control, the especially for the door hinge mutual Mounting is suitable, albeit a door hinge side Assembly possible is. About that In addition, such a blocking device arranged with an inventive Locking lever alike together with slide rail door closers and also with scissor linkage or articulated arm door closers combined become.

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 Feststellpo tion, in particular the minimum opening position, 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 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 angular proportional (regarding 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.

simultaneously allows This device thus a particularly accurate detection of the active leaf in the minimum opening position. This is especially true for the case that the door closer used Slide rail door closer is. By the articulation of the locking lever on the toggle between the in the projection of both outer pivot points succeeds to ensure it is particularly elegant that the locking lever over the entire closing movement of the active leaf a movement in one direction, even at a hyperextension of the locking lever passes. This allows especially in a band-mutual installation the exact vote the braking behavior of the blocking device, especially in the area the closing angle <40 °, especially <30 ° and especially also in the range <20 °. One episode the knee lever assembly of the three pivot points to each other is that the areas between the two outer pivot points of the toggle lever when pivoting the toggle lever from its open position Doors in theirs Position with the door closed In any case, perform a partial movement over the entire opening process in one direction and over the entire closing process oriented in the other direction. This is especially true then, if the fulcrum of the guide axis of rotation while the closing or opening movement of the active wing not in the projection plane the entire pivoting process is performed in one direction, as it is the case, for example, in the band mutual installation of a Gleitschienentüröffners the Case is. By means of the additional Locking lever manages to derive this partial movement of the toggle lever and as a point of attack for the blocking device available to deliver. The articulation of the locking lever on the toggle takes place preferably obliquely to the trajectory of the slider in the projection plane, ideally at right angles. Another central idea of the invention lies Thus, to provide a locking lever in the manner of the Knee lever acts to block or block the movement of the Door leaf in Door closing direction is provided, wherein the locking lever is formed and arranged is that he has his blocking force obliquely on the toggle with respect to the Moving path of a point on the knee lever applies, which extends over the entire opening path in one direction and over the entire closing path moved in the opposite direction. In other words, the locking lever according to the invention allows from the toggle one over the entire closing process derive rectified, ideally angle-proportional, motion on which the blocking device acts for blocking purposes.

The Advantages of the invention are particularly evident in particular when the door closer on the other side of the tape is mounted, because there especially the movement reversal of the slider in the slide during the closing or the opening process can be observed. The inventive arrangement of the locking lever between the toggle and the blocking device allows the occurring at Gleitschienentüröffnern "negative", ie in terms of the initial opening movement opposite, Gleitweg the slider to bypass.

The Storage of the locking lever on the wall area is particularly with regard to on the required installation work of advantage. The pivot bearing the locking lever is in this embodiment together with the Blocking arranged on the fixed wall area. With At its other end, the locking lever on the toggle lever is over articulated suitable connection.

Basically, the locking lever can articulate 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.

Prefers are the locking lever and the locking arm together in one plane, in particular in the form of a horizontal gear, in particular a four-bar mechanism, arranged. The drive of the gearbox forms while the blocking lever on a blocking force performing door lock ßer. Essential for this embodiment is that the movement of the locking lever and the locking arm substantially take place in a horizontal plane to each other. This is the result Space requirement of this embodiment in the vertical direction particularly low. This embodiment is thus special space-saving feasible. Equally, the side of the inactive leaf can also be used have such a transmission with a corresponding door closer. The geared configuration the inactive side will be even closer be set out.

The Concrete training of the locking lever can be done in different ways and ways are realized. As particularly advantageous has a at least two-armed locking lever exposed, the one arm on the knee lever and the other arm on the blocking device is articulated. The linkage can thereby indirectly and alternatively also be immediate. In this embodiment, the locking lever furthermore, preferably in the intersection region of the first and the second arm, a pivot bearing with a separate axis of rotation (blocking lever pivot axis) and thus also its own pivot point in the projection plane orthogonal to the bearing axis. The two-armed locking lever is thus independent of the articulation on the toggle lever and on the blocking device separately stored.

Prefers stand the two arms of the two-armed locking lever in a blunt Angle to each other. It is also beneficial the two-armed Locking lever in one piece train. As a result, the locking lever acquires a particularly stable Constitution. Alternatively, of course, the locking lever be multi-part, for example, the customization options the device according to the invention for closing sequence regulation to different double-winged Relieved doors.

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

Also the concrete formation of the connection of the locking lever with the knee lever, generally referred to as articulation, may be different Ways are realized. Basically, within the scope of the invention overlapping and overlap-free Connectivity includes. It is preferred for articulation of the locking lever on the toggle lever a tax slope present, along which a guide element guided is. The guide element is for example a protruding bolt. Control slope and guide element are opposite each other, on the locking lever preferably the control slope and the toggle before given to the guide element, arranged. This type of articulation allows a particularly flexible use the device according to the invention for closing sequence regulation and lets by using a tax slope also a certain game in the arrangement of the individual elements, so that the handling the device according to the invention for closing sequence regulation a double-winged Door considerably is relieved.

Especially It is elegant, the tax incline in a slot guide to integrate. This ensures that the locking lever always guided on the knee lever is because the slot is the guide element in the management level (which ideally the pivoting plane of the locking lever and especially additionally parallel to the projection plane) surrounds and thus in each Direction of movement in the management level a guide of the guide means guaranteed in the slot is. As long as the locking lever exerts no locking force on the toggle, is the locking lever due to the long hole engagement therefore also passive moved with the knee lever. The tax slope is in this case in shape one the guiding means formed in the oblong hole plane control slope, that of the guide element is at least partially penetrated in a suitable manner.

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 presses it thus 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).

Basically it is possible over the locking lever on the knee lever the entire opening path of the door leaf (for example from a door opening angle from 0 ° to maximum 115 °) carry. The blocking device is preferred in this embodiment also in the manner in which a determination of the locking lever by the blocking device and thus a determination of the knee lever or of the active wing over the entire swing range possible is. As it is however for the closing sequence regulation essentially to those opening angles of the active wing arrives at which the inactive leaf no longer on the active leaf can swing past (this is basically dependent on concrete training of doors; usually However, this range is at door opening angles <20 °), lies It is also within the scope of the invention to form the locking lever in such a way that he only for this limited area is carried on the active leaf. The guide element and the tax slope are in this embodiment formed accordingly in the manner that the guide means from the crossing a fixed opening angle released or except Engagement with the control slope comes. The tax slope rather remains in a certain position (Auffangstellung or collection position), in which they guide the closing process can catch up in time. This position is chosen so that the leaf in an opening angle kept that big enough is that the inactive leaf on the moving wing can swing past. Below this position of the locking lever also referred to as catchment position.

To There is a locking lever stop against which the locking lever in the opening direction or strikes its direction of movement at an opening of the active leaf. Of the Lock lever stop is ideally so on the device for closing sequence control arranged that the locking lever at an opening angle of the active leaf <40 ° in particular <30 °, especially <25 ° and especially <20 ° to the locking lever stop strikes or is caught by this. In this way, the locking lever must no over the entire opening stroke of the active leaf carried away And at the same time it is ensured that the active leaf in time while closing held by the locking lever or the blocking device in the minimum opening position can be.

There Doors especially with regard to the rabbet widths, the door frames or door leaf widths etc. can strongly differentiate has the use of one, especially with regard to the opening angle the locking lever stop, adjustable locking lever stop as particularly advantageous. An adjustable locking lever stop allows it, the device of closing sequence control particularly easy to adapt to the individual circumstances. adjustment exist in particular with regard to the collection position or in terms of the door opening angle, in the aisle over the Lock lever is detected maximum.

In a further embodiment The invention is the locking lever with its locking lever pivot axis mounted on a slidably guided in a slide slide, wherein the slider over the Blocking device is lockable. The basic execution of Slide rail and guided therein Slider can be based, for example, on the already known sliding rail door closer. In contrast to the known Gleitschienentürschließer, it is according to the invention, however provided, in addition the locking lever in the device for the closing sequence control to integrate, in the manner set out above on toggle is articulated. An adjustment of the locking lever is easy Way by a displacement of the corresponding slider along the slide rail possible.

Already from the foregoing you can see it for the invention is particularly advantageous when the door closer a Sliding rail door closer is, its closing arm at his door closer opposite Endbereich a rotatably mounted relative to the locking arm and in a slide guided Slider has. Especially with a slide rail door opener in the case of tape-mounted installation, the end point of the closing movement of the active wing problematic to determine, as the slider towards the end of the closing movement reverses its direction of movement in the slide rail. The inventive device for Closing sequence control bypasses this problem by the integration of the locking lever in the as described above. This makes it possible, in particular Gleitschienentürschließer particular for the band mutual Mounting to use, even if in principle a band-side mounting possible is.

constructive it is advantageous if the slide both the slider of the closing arm as well as, if present, the slider of the locking lever leads. On this way a total of only one slide is required, thereby not least, the installation costs can be reduced.

Basically it also possible that the locking lever articulates the toggle lever in an area that in the projection plane structurally from the door leaf formed the active wing becomes. This embodiment is especially for Such a locking lever advantageous in the above-described Way on a slidably guided in a slide slider is stored. The locking lever is in this embodiment in the pivoting plane arranged in the area bounded by the toggle and the door frame becomes. In this way, therefore, a particularly space-saving arrangement the toggle lever together with the locking lever possible.

One Another advantageous basic idea of the invention lies in the execution of triggering device the device for closing sequence control. Basically the triggering device in the manner known from the prior art. Part of the triggering device is usually a Another door closer, preferred also a Gleitschienentürschließer, the arranged between the adjacent wall area and the inactive leaf is. This one is wearing make sure that also the inactive leaf is subjected to a door closing force, so that it is pressed into its closed position. To open the fixed leaf Therefore, at least this door closing force must be overcome.

It has now shown that the concept of the locking lever in relation on the active wing in an advantageous manner also basically transferred to the triggering device leaves. In a preferred embodiment picks up the triggering device therefore about a locking arm and a slider to a slide, wherein the bearing axis of the low-wing side Door hinge, the door closer rotation axis of the stood leaf side Door closer and the guide axis of rotation of the slider in a projection in the plane orthogonal to the axial direction the bearing axis of rotation of the passive leaf are arranged in such a way that they are together with the two in between Areas altogether form a toggle whose stationary linkage is the pivot point of the bearing axis with respect to the projection plane, and the other pivot points of the door closer rotation axis and the guide axis are formed, wherein a pivot control lever is present, the is articulated on the toggle lever and is formed in such a way that he the triggering device dependent on operated from a fixed position of the inactive leaf. The above set forth for the locking lever Advantages apply in principle also for the Swing control lever of the triggering device. This concerns in particular the definition of the triggering point in the case of mating walls Assembly of the door closer, there Again, the slider in the slide to the end of the closing movement of the passive one opposing Movement performs. Due to the special articulation of the swivel control lever on the toggle lever however, it is possible a rectified movement over derive the control lever from the knee lever and to control the triggering device consulted.

Preferably is for operation the triggering device Further, a pull rod between the swivel control lever and the triggering device arranged, which is formed in such a way that it the triggering device operated on train. The integration of a pull rod instead of the previously used Push rods is advantageous in that the material load of the control linkage thereby is significantly reduced and so, for example, bends or the like damage, such as in particular a buckling of the rod, which could lead to erroneous functional sequences, in Prevented can be avoided in advance. The tie rod is ideally arranged in such a way that they are essentially in one plane with the panning control lever and the locking arm lies and together with this forms a horizontal gearbox.

The Blocking device can in the usual way and be formed. Preferably, the blocking device For example, a clamping device, which in its clamping position the blockage or determination causes, and in their release position in the non-blocking state. The concrete education of the functional Connection between the blocking device itself and the locking lever can vary. So it is possible, for example, the locking lever directly with the blocking device, in particular the clamping device, connect to. 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 by simply sole adaptation of the locking member adapted to different types of doors become. An individual adaptation, for example, the locking lever, the Blocking device and other components, however, is not required. The blocking member may, for example, a corresponding, possibly also be multi-part, locking bar.

In a further embodiment of the invention, in which the blocking device comprises a locking element articulated on the blocking lever, in particular a blocking rod ( 23 ), and wherein the locking member via an adjusting rod with a clamping device is connected, the customization options are once again 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 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, on the sole length adjustment, the entire device for closing sequence control to the respective door width is customizable.

In In terms of production technology, it is advantageous if the Drawbar at least in their articulation areas and in particular in their entirety identical to the locking member, in particular the Locking rod, is formed. The articulation area comprises the Areas of the drawbar, over these connected with the functionally connected with these components is. In this way, the number of different parts a device according to the invention for closing sequence regulation be significantly reduced. About that also allows In particular, this embodiment of the invention, the device for Closing sequence control both right and left anzuord NEN (based on the Leaf). Only the location of the blocking device and the triggering device must be exchanged with each other.

It is according to the invention possible, the blocking device and the triggering device directly with each other mechanically connect. Alternatively, however, it is also possible to have a transmission medium to provide between the blocking device and the triggering device, the an operation the triggering device through the passive wing transmits to the blocking device in such a way that these from the blocking position switches to the release position. Such transmission means may, for example Bowden cables, be electrical cables, etc. In this way, for example the area between the blocking device and the triggering device (usually in the middle of the upper part of the door frame) be kept free, so in addition Components such as alarms, emergency exit displays or similar can be integrated into this position.

at the following Representation forms are identical components with the same reference numerals Mistake. Furthermore, for reasons of clarity in part not every component provided with a reference numeral in a figure in all other figures also provided with a reference numeral, even if it is visible there.

The double-leaf door 1 according to the 1a to 7 includes a moving leaf 2 and a pug leaf 3 , The active leaf 2 and the passive wing 3 are in a doorway 4 stored, which is part of the adjoining the door wings wall area. For storage is on the active leaf 2 the door hinge 5a and the door hinge on the passive leaf 5b available. The hinges 5a and 5b are about a stationary bearing axis L (active leaf 2 ) or L (passive leaf) 3 ) rotatable or pivotable and can of course also several joints between the respective door leaf 2 or 3 and the wall area adjacent thereto. The active leaf 2 and the passive wing 3 are both in the opening direction O ( 1c ) aufschwenkbar, that is, for example, in 1a into the picture plane, or in 1b out of the picture plane.

The active leaf 2 and the passive wing 3 each have a fold 6a (for example, according to 1a ) respectively 6b (for example, according to 1b ) on the other wing in the closed state of the two-leaf door 1 partially overlapped. The gangway side fold 6a lies in the opening direction O in front of the inactive leaf 3 and the low-wing side fold 6b in the opening direction O behind the active leaf 2 , This causes to close the open double-leaf door 1 a certain closing order must be adhered to the active leaf 2 and also the passive wing 3 to be able to pivot in the respective closed position. This results, for example, particularly clearly from the top view 3b , To close the two-leaf door 1 Therefore, it is necessary that the inactive leaf 3 in front of the active wing 2 gets into its closed position or the active leaf 2 is held in a fixed minimum opening position or at a fixed opening angle α, which is dimensioned so that the inactive leaf 3 on the moving wing 2 can swing past in its closed position to a resting of the inactive leaf 3 on the fold 6a of the (closed or almost closed) active leaf 2 to prevent.

This allows a device for final order regulation 7 comprising a blocking device 8th , a triggering device 9 and one between the active wing 2 and through the door frame 4 formed wall area arranged door closer 10 , The door closer 10 points you to the active wing 2 acting closing arm 11 on, with the door closer 10 is formed in such a way that he the locking arm 11 acted upon by a closing force in a known manner, in the manner of the active leaf 2 is transmitted from an open position (for example, according to the 3a and 3b ) in a closed position (for example according to the 1a to 1c ) is pressed. The locking arm 11 is at its one end area 12a about a door closer rotation axis T rotatable on the door closer 10 hinged and at its other end 12b rotatably mounted about a guide axis of rotation F, in the present embodiment concretely in a slide rail 15 linear guided glider 16 ,

The axially extending in their axial extension bearing rotation axis L, the door closer axis T and the guide axis F are arranged in a certain relationship to each other in such a way that they in a projection of the three axes of rotation in a plane E orthogonal to the axial direction of the bearing axis L in the manner lie to each other, that together with the two intermediate areas B1 and B2 a toggle lever 13 form or in the form of a toggle lever 13 are arranged. The position of the projection plane E relative to the bearing axis of rotation L is in 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 4b respectively 4c parallel to the image plane. The 4c and 5b (or with regard to further embodiments also the 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 4b the pivot point of the door closer rotation axis T) in each case with the two outer pivot points (in 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 the area B1 and B2 lying between the fulcrums L and T and T and F, respectively. In the outline sketches of the 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. In relation to 4c It follows, for example, that the area B2 is essentially solely by the closing arm 11 is formed. In contrast, the region B1 or the line of action of the lever arm between the bearing axis of rotation L and the door closer rotation axis T partially encloses a region of the door closer 10 as well as the door leaf of the active wing 2 , The in the 4b and 5b (or with regard to further embodiments also the 8b and 10d ) Schematic diagrams serve merely to illustrate the design of the toggle lever 13 and its articulation by a locking lever specified in more detail below 17 , In particular, the regions B1 and B2 can also be realized in other ways, for example also by embodiments that are not formed massively along the connecting lines (corresponding B1 and B2). 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 paging wing side (as in the embodiments given in the figures and as it is usually the case when using a Gleitschienentürschließers the case) or wall side is arranged.

The concrete training of the blocking device 8th can also vary. In the concrete 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 a guided through the clamping device and parallel to the slide rail 15 extending adjusting rod 14 is guided.

The design of the adjusting rod 14 is particular in 7 specified. Accordingly, the adjusting rod comprises 14 partly by the blocking device 8th guided clamping area 18 and one in the direction of the active wing 2 adjoining adjustment area 19 , Both areas 18 and 19 are via a connecting joint 20 interconnected, with the connecting joint 20 a U-shaped receiving fork 21 at the clamping area 18 includes the adjustment area 19 embraces in a fork-like manner in its tip region and via a pin connector with a mounting hole (in 7 not shown) in the clamping area 18 connected to this. At predetermined intervals, the adjustment range 18 a plurality of spaced-apart similar joints on (Justierlöcher 22 and 22 ' ), which is a width adjustment of the length of the adjusting rod 14 allow for the width of the respective double-leaf door. For this purpose, for example, from the factory relatively long adjustment range 19 the adjusting rod 14 (with, for example, more than two alignment holes 22 and 22 ' ) capped to the required length and then each to the inactive leaf 3 outward adjustment hole for the pin connector to the clamping area 18 used. At the in 7 given embodiment, the connection to the receiving fork 21 however, always on the same mounting hole and the width adjustment of the adjusting rod 14 by capping the length to the leaf 2 out. This is the adjustment range 19 the adjusting rod 14 connected to its other end also via a pin connector with the gangway side mechanism of the device for closing sequence control, specifically with a locking member 23 (in 7 only partially visible), which at its other end on the locking lever 17 is articulated. However, this pin connector includes a carriage 24 through which the adjustment range passes 19 is guided. The sled 24 is rotatable with the locking member 23 connected. The distance between the individual adjustment holes 22 and 22 (And possibly 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 8th allows the leaf 2 at least in a minimum opening position in the door closing direction or contrary to the opening direction O determine. This minimum opening position is in the embodiment according to the 1a - 7 for example, at an open 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 and also in the projection plane orthogonal to the bearing axis of rotation L. The blocking device 8th 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 when opening the inactive leaf 2 over a fixed trigger point (in the present embodiment, this trigger point is already at a few degrees door opening) in his then present door opening angle is determined. Alternatively, the device for closing sequence control is formed in such a way that the active leaf 2 even when triggered (ie blocking) blocking device 8th in the door opening direction O beyond the minimum opening position further aufdrückbar is, but then by the door closer 10 on the active wing 2 applied door closing force is pushed back to the minimum opening position. Essential for the operation of the blocking device 8th in that the clamping device is a longitudinal displacement of the adjusting rod 14 prevented in the blocking state. This determination of the adjusting rod according to the invention via the locking mechanism described in more detail below on the active leaf 2 transfer.

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

The locking lever 17 is designed with two arms, with one arm 24 with the locking member 23 and the other arm 25 is connected to the locking lever. The two arms 24 and 25 are in the pivoting plane of the locking lever 13 arranged at an angle of about 135 ° to each other. The locking lever 17 is in one at the front of the slide rail 15 arranged locking lever bearings 26 stored on the door frame or wall side and pivotable about the locking lever bearing pivot axis S. The axial direction of the rotation axis S is parallel to the axial directions of the rotation axes 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 on the locking arm 11 of the aisle-side door closer 10 hinged.

The linkage comprises a slot 27 at the end of the other arm 25 into the one on the locking arm 11 arranged and from this in the direction of the locking lever 17 protruding guide pin 28 protrudes. The slot 27 thus provides a control slope along its inner edge for the guide pin 28 to disposal. 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. Will the locking lever 17 according to the blocking device 8th over the adjusting rod 14 and the locking member 23 prevented at a pivoting at least in the door closing direction or against the door opening direction, acts as a guide element acting guide pin 28 against the control slope and is characterized by a continuation of his from the toggle 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. So that the guide pin 28 against the control slope in the longitudinal direction of the slot 27 can strike, they need in the present embodiment with the Gleitschienentürschließer 10 at least in their relative position to each other when located in the minimum opening position leaves 2 tangential in the closing direction of the guide pin 28 and obliquely to each other in the direction of the control slope. In contrast to the previous closing sequence regulations, especially for Gleitschienentürschließer, a determination of the active leaf 2 about a fixation of the position of the slider 16 in the slide rail 15 provided, the invention goes the way on a glider 16 bridging locking mechanism with inter alia a locking lever 17 that about the blocking device 8th is detectable and on the locking arm 11 of the door closer 10 is articulated. The of the blocking device 8th Outgoing blocking force is thus in particular with the cooperation of the locking lever 17 on the knee lever 13 transferred and acts of the door closer 10 in the door closing direction outgoing Door closing force with locked blocking device 10 opposite.

The 4c and 5c clarify the articulation of the locking lever 17 on the toggle 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 plane of projection 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 opening and closing operation, whereas the length of the locking lever 17 formed lever between S and A due to the slot guide 27 changes over the panning process. The guide element 28 thus slides over the pivoting process away 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 device is that the transmission of the blocking force is no longer on the in the slide rail 15 guided skid 16 but over the locking lever 17 he follows. The blocking device 8th thus causes over the locking lever 17 comprehensive locking mechanism the determination of the active wing 2 (at least in its minimum opening position) with open (or over the trip point away open) fixed leaf 3 , The 4c and 5c further clarify that the locking lever 17 is hinged to the knee lever between the two outer pivot points T and F in the projection plane E (this corresponds in the embodiment according to the 1 to 7 the area B2). 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 17 thus deflects the locking mechanism at a location detached from the slider position in the slide. Therefore, this device for closing sequence control is also ideal for use on the strip side, since in this way can be used in a particularly simple and elegant other points for the articulation of the locking mechanism, related to the opening movement of the active leaf 2 move in the same direction relative to the plane of movement at least in one direction over the entire opening process and 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. But the invention also allows the articulation of the locking lever 17 at points on the toggle 13 which are rectified only with respect to a direction of movement in the projection plane E, but in other directions of movement in the projection plane but move in opposite directions over the opening or closing operation. It is essential that the articulation of the locking lever 17 on the toggle 13 in the manner that the guide element or the guide pin 18 on a continuation of his movement when closing the active wing 2 by a stop on the (detected) control slope (or the locking lever 17 ) is prevented or the locking lever 17 transmitted blocking force obliquely on the knee lever 13 is applied. In the blocking position (in particular in the blocking position in the minimum opening position), the pivoting movement of the blocking lever 17 and the articulation point on the toggle lever 13 to such an oblique transfer of the blocking force ideally to each other so that the tangent to the closing movement of the guide element (ie, their movement in the continuation of 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 through the blocking device 8th is the triggering device 9 provided, whose basic structure and its mode of action in the 6a and 6b is shown in more detail. 6a is an enlarged detail of the dotted framed area 4a and 6b is a schematic diagram of the lever assembly 6a in the projection plane E (the dotted connecting lines against the position of the individual pivot points S ', A', L ', T', and F 'in the 6a and 6b at). The triggering device 9 is designed in such a way that it depends on the position of the inactive leaf 3 the triggering device 9 activated.

In the main features is the release mechanism on the side of the passive 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. So is in particular a two-armed control lever 17 ' present (area B1 and B2 'in analogy to the area B1 and B2), the front side to the slide rail 15 is pivotally mounted on the inactive leaf side (parallel to the projection plane E). The control lever 17 ' is on the one hand on the locking arm 11 ' of the door closer 10 ' hinged and at his whose end with a transfer link 23 ' functionally coupled. The door closer 10 ' , the pivot lever 17 , the transmission link 23 ' and the locking arm 11 ' are identical to the arrangement described above on the part of the active leaf 2 , A reversed arrangement thus requires only a conversion of the arrangement of the blocking device 8th , the triggering device 9 and the adjusting rod 14 , The actual operation of the triggering device 9 takes place via a wrap 29 in the end region of the transmission element 23 ' that 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 moved against the door opening direction O) and thus operated on train. In the actuated state of the triggering device 9 is the blocking device 8th 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 band-opposing mounting, over the entire opening and closing movement of the inactive leaf 3 a rectified movement to control the triggering device, even if in particular the slider 16 ' while the end of the closing movement reverses in its direction of movement. Thus, in particular, the side of the inactive leaf also comprises a toggle lever arrangement, that of the control pivoting lever 17 ' in the manner of the locking lever described above 17 is articulated.

An alternative embodiment of the device for closing sequence control is in the 8a to 9b shown, with both the inactive leaf 3 as well as the active wing 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 not at every opening angle of the active leaf 2 is possible, but only from a door opening angle of> 0 ° to about 40 °. For beyond door opening angles is a determination of the active leaf 2 not possible in these positions. Is the active leaf 2 when the blocking device is activated 8th in a door opening angle of about 40 °, it is from the door closer 10 rather pushed back in the direction of its closed position up to a door opening angle of about 40 ° or the maximum possible locking angle.

These special control properties of this embodiment are essentially based on the special design of the locking lever 30 Back, unlike the locking lever 17 no closed on all sides of the pivot plane slot has, but rather a to one side in the pivot plane "open" slot with corresponding control slope 32a , Due to the design as "open slot" is the control slope 32a Part of a substantially fork-shaped locking lever 20 comprising a base body and two elongated and mutually parallel tines arranged thereon. The control slope runs essentially on the slide rail 15 facing inside of the closing direction of the locking lever 30 front tine. This embodiment of the control slope allows that guided at least in the range of the door opening angle of 0 to about 40 ° guide element 31 (In this embodiment, a coaxial with the door closer rotational axis T between the closing arm 11 and the door closer 10 arranged guide ring is) abuts only in this area 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 element arrives 31 out of engagement with 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, the locking lever 30 in its maximum opening position or in the direction of the stop urges. As long as the locking lever 30 not in engagement with the guide element 30 is, the locking lever takes 30 therefore still a defined position. This position is referred to as a "catching position" because a minimum requirement of this defined position is that it is suitable for the guide element 30 of the closing active leaf 30 catch to ensure the 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 blocking mechanism, the basic mode of operation of which has already been explained above.

Compared to the previous embodiment is also the concrete articulation of the toggle lever 13 through the locking lever 30 varied. In contrast to the previous embodiment, the locking lever 30 not here in the area of the knee lever 13 between the pivot point in the projection plane E of the door closer rotation axis T and the guide axis F hinged to the toggle lever, 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 element 31 , The corre sponding arrangement of the toggle 13 and the locking lever 30 in the pro at sub-level E are in 8c specified. The dotted lines indicate (as with the 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 special feature of this embodiment is that the triggering mechanism of the inactive leaf side in contrast to the previous embodiment with a pivot lever 30 ' is equipped for control purposes, in contrast to the previous embodiment also has an open to one side slot with a corresponding control slope, which is adapted for engagement with a mounted on the door closer rotation axis of the door-side door closer guide element (in the basic structure corresponds to the control mechanism except for the articulation of blocking device 8th and the triggering device 9 the structure of the control mechanism on the active leaf side). Furthermore, the pivot lever is also 30 ' spring loaded and proposes at a defined opening angle against a stop. 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 8th and the triggering device 9 each must be adjusted. On the other hand, the opening angle of the passive leaf is 2 not over the entire swing range of the inactive leaf 3 Be detected by 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 catchment position of the inactive leaf 3 equivalent. This door opening angle is suitably chosen such that the determination of the active leaf is ensured when the inactive leaf 3 for closing the two-leaf door on the moving leaf 2 must go past.

The 10a to 10e Finally, show a third embodiment 1'' the invention. Similar to the previous embodiment deflects also in this embodiment, the locking lever 33 the toggle 13 not over the entire swing range of the active leaf 2 but only from door opening angles from about 40 and less. Also in this embodiment, the active leaf 2 thus when closing from a certain door opening angle of the locking lever 33 captured. Another special feature of this embodiment is that the locking lever 33 a hook 34 against which the on the active leaf 2 in a receiving element 35 between two horizontal legs mounted bolt-like guide element 34 strikes upon reaching the catchment position. The tax slope 36 is here therefore in the hook 34 integrated.

The receiving element 34 is on the door leaf of the active wing 2 on the side of the door closer 10 arranged. Thus, this embodiment is further characterized by the fact that the articulation of the toggle lever 13 , in particular from the projection representation in 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. 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 in its concrete embodiment, the knee lever obtained in the projection plane 13 indirectly via a fixed with the toggle lever 13 connected area 36 hinging.

Another essential feature of this embodiment is the special storage of the locking lever 36 , This is in the area of the locking lever bearing pivot axis S in the slide rail 15 on a glider 37 stored, in which also the glider 16 is guided. The blocking device 8th is designed in such a way that they have a to the adjusting rod 14 subsequent locking bar (not visible), which is also in the slide rail 15 is guided, with the slider ( 37 ) is operatively connected and in this way the blocking function of the locking lever 33 controls.

As in the previous embodiment, the triggering mechanism on the inactive leaf side is also here except for the concrete articulation on the blocking device 8th and at the triggering device 9 arranged identically and reversed, so that even here a quick change from the right-side mounting on the left-side mounting is possible.

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