EP2896773B1 - Control of closure sequence - Google Patents

Description

The invention relates to a closing sequence control according to the features of the preamble of claim 1.

Closing sequence controls are used in practice for double-leaf doors that close automatically by means of a door closer to ensure that both door leaves are in the correct closed position. For the correct closed position, it is necessary that the so-called passive leaf always comes into the closed position first before the so-called active leaf closes. To ensure this, a closing sequence control is used which blocks a closing movement of the active leaf until the inactive leaf has reached the closed position.

The person skilled in the art knows several solutions for such closing sequence controls from practice. In general, the closing sequence controls controlled depending on the movement of the sliding elements guided in a slide rail of the door closer.

If the door closers are installed on the opposite hinge side, however, it must be ensured that the direction of movement of the sliding elements of the door closers is reversed shortly before they reach the closed position. During the closing process, this movement first takes place in the direction of the closing edge of the door leaf. However, shortly before reaching the closed position, this movement is reversed due to the geometrical conditions, so that the sliding elements move a short distance in the direction of the hinge side of the door leaf. Appropriate precautions must be taken to take this movement reversal into account. Such a functional principle is, for example, from the EP 1 544 398 A2 known. In this document, a vertically displaceable release element is actuated by the sliding block to block the active leaf. The disadvantage here is the necessary overall height of the slide rail.

From the EP 1 333 142 A2 a generic closing sequence control is known which is suitable for mounting on opposite hinge sides. A double-leaf door with sliding arm door closers is shown there. Both door leaves are rotatably mounted on a door frame via hinges. The door leaves are actuated in the closing direction via the sliding arm door closers. In order to ensure the correct closing sequence of the two doors, the sliding arm of the passive leaf door closer is connected at its end with a cranked hook which releases a blockage of the active leaf via a release element as soon as the passive leaf comes into the closed position. This is done by the hook coming into contact with one side of the release element in the area of the closed position of the inactive leaf and then actuating it by the backward movement of the sliding arm. This solution is different from a closing sequence control controlled by a sliding block Functional principle that enables a lower slide rail. The disadvantage of this solution is that the cranked hook is difficult to adjust, and requires a certain minimum height, which is not always guaranteed in practice.

The EP 1 126 118 B1 also shows a closing sequence control which is suitable for mounting opposite the hinge. The sliding arm has an integrated hook arranged at the end which releases a blockage of the active leaf via a release element as soon as the inactive leaf comes into the closed position. The disadvantage of this solution is the lack of adjustability of the closing sequence control.

The EP 0 458 034 A1 also shows a closing sequence control for double-leaf doors for installation on the opposite hinge side. To release the blocking of the active leaf, the device described has a release roller and a release pin. A slide tongue is arranged on the sliding block of the inactive leaf sliding arm, which actuates the release pin when the inactive leaf is moved into the closed position in order to unblock the active leaf.

The invention is based on the object of creating a closing sequence control which is suitable for installation on the opposite hinge side. The closing sequence control should be compact and easy to assemble. The closing sequence control should preferably have a high level of operational reliability, that is to say ensure the correct closing sequence of the doors in every case. According to the invention, this object is achieved by a closing sequence control having the features of claim 1.

According to the invention it is provided that the sliding arm of the passive leaf door closer has an actuating element in the area of its free end, which interacts with a release lever of the control device via a roller to release the blocking of the closing movement of the active leaf. When the blocking of the active leaf is released, the roller rolls on a rolling surface which is arranged on the actuating element. This solution minimizes disruptive frictional forces and is particularly important with a compact design reliable operation of the closing sequence control achieved. Disturbing influences due to friction or inaccuracies of fit are reduced or compensated for by the roller running on the rolling surface.

The area of the free end of the sliding arm of the passive leaf door closer, or also the passive leaf sliding arm, is arranged at the end of the sliding arm in the area of the attachment of the sliding arm with a sliding element or sliding block. It lies opposite the end of the sliding arm, which is connected to a shaft of the door closer so that it cannot rotate. The active leaf is not blocked by the sliding block, but by an actuating element arranged in the area of the free end of the fixed leaf sliding arm. This enables a compact design with high reliability at the same time. According to the invention it is provided that the actuating element is connected to the free end of the sliding arm, in particular is detachably connected. In particular, the inactive leaf sliding arm has the actuating element in the region of its free end, which is arranged in addition to the sliding block on the inactive leaf sliding arm and / or connected to it.

In one embodiment it can be provided that the release lever rotatably supports the roller in the area of its free end. The free end of the release lever interacts with the actuating element to release the blocking, so that the arrangement of the roller in this area is a particularly space-saving and compact solution. The free end of the release lever is the end which is arranged outside the slide rail. In an alternative embodiment it can be provided that the actuating element receives or supports the roller.

In one embodiment, the roller can advantageously be arranged in the area of the plane of rotation of the inactive leaf sliding arm in order to reduce the required overall height. It is preferably provided here that the roller is rotatably mounted about an axis which is arranged in the area of the plane of rotation of the inactive leaf sliding arm. This results in the advantage that no additional installation space extending above or below the plane of rotation is required.

The plane of rotation of the sliding arm of the passive leaf door closer is defined as the plane in which the passive leaf sliding arm moves or rotates. The plane of rotation of the sliding arm of the passive leaf door closer usually runs more or less at right angles to the plane of the door defined by the closed position of the door leaf.

In one embodiment it can be provided that the control device has a rotatably mounted release lever which extends out of the slide rail into the plane of rotation of the inactive leaf sliding arm in order to interact with the actuating element for releasing the blocking of the closing movement of the active leaf. It is thus possible for the control device to be arranged within the slide rail. The slide rail encloses the control device and protects it against disruptive mechanical influences and contamination.

In one embodiment according to the invention it is provided that the sliding arm of the fixed leaf door closer is connected to the actuating element via a detachable plug connection. In one embodiment, the sliding arm has a plug-in receptacle into which the body of the actuating element can at least partially be inserted. In particular, at least a portion of the body of the actuating element can be designed so that it is between two Limits of the sliding arm engages positively. In another, equivalent embodiment, the actuating element has a plug-in receptacle into which the body of the sliding arm can at least partially be inserted. In particular, the body of the sliding arm can be shaped in the region of its free end in such a way that it engages positively between two boundaries of the actuating element. In this way, a secure connection between the actuating element and the sliding arm of the passive leaf door closer can be implemented in a limited space. This refinement therefore has the advantage of ensuring a reliable function of the closing sequence control with a particularly compact structure.

Another embodiment of the invention provides that the sliding arm of the fixed leaf door closer is connected to the sliding element guided in the sliding rail via a bearing pin, and this bearing pin firmly connects the sliding arm to the actuating element. Thus the bearing pin fulfills two tasks at the same time. On the one hand, it connects the sliding arm of the passive leaf door closer to the sliding element and, on the other hand, it connects the sliding arm of the passive leaf door closer to the actuating element. In this way, the number of components required for closing sequence control is reduced without negatively affecting the function.

In one embodiment, it can preferably be provided that the connection between the bearing pin and the sliding element or sliding block is designed to be rotatable in order to ensure the rotational movement between the sliding arm and sliding element that is required when closing or opening the door leaf. For this purpose, either the sliding element or the bearing pin can have a pivot bearing. For example, a rotatable sleeve can be provided which is non-rotatably connected to the sliding element and rotatably mounted on the bearing pin. A mechanically firm connection between the sliding arm and the actuating element is achieved by providing in one embodiment that the bearing pin connects the sliding arm to the actuating element in a rotationally fixed manner. For this purpose, the bearing pin can have a clamping device, preferably a clamping screw, which firmly connects the sliding arm to the actuating element by clamping the sliding arm against the actuating element.

In an advantageous embodiment it is provided that the bearing pin has a support collar on which a surface of the actuating element rests directly. The support collar pulls the slide arm via a clamping element, preferably a clamping screw, the actuating element lying directly on the support collar in order to clamp them against one another.

In a further embodiment it can be provided that the control device has a bearing element and a release element. The blocking device can be released by the actuating element moving the bearing element relative to the triggering element by interacting with the control device. The blocking device can also be released by the actuation element moving the release element relative to the bearing element through the interaction with the control device. This relative movement of the two elements of the control device to one another results in a stroke which can be used for reliably releasing the blocking device.

Preferably, it can be provided that to adapt the closing sequence control to local conditions, or to compensate for tolerances, an adjustment area is provided within which the actuating element on the inactive leaf sliding arm can be freely displaced and firmly connected at any point. An adjustment range is a range from 10mm to 100mm within which the actuating element at the end of the inactive leaf sliding arm can be freely displaced without the connection being mechanically weakened.

It can also be provided in one embodiment that the position of the control device within the slide rail can be adjusted for adjustment.

By adjusting the position of the actuating element or control device, tolerances or deviations in the dimensions can be compensated for. For an adjustment of the control device it can be provided, for example, that the position of the bearing element and / or the position of the release element within the slide rail can be adjusted. The position of the bearing element and / or the position of the release element can be shifted along the slide rail and fixed in the correspondingly desired position.

In order to achieve universal use of the closing sequence control, it can be provided in one embodiment that the actuating element is connected to the inactive leaf sliding arm in such a way that it can be connected to the inactive leaf sliding arm either in 0 ° or in a position rotated by 180 ° with respect to its longitudinal axis. This ensures that the actuating element can be used regardless of whether the passive leaf is designed as a right leaf or a left leaf.

In one embodiment of the closing sequence control it can be provided that the actuating element has a C-shaped or U-shaped groove which engages around one side of the body of the inactive leaf sliding arm. In this way, the actuating element can simply be pushed onto the end of the fixed leaf sliding arm during assembly.

For a particularly good connection between the inactive leaf sliding arm and the actuating element, it can be provided that the actuating element has two opposing C-shaped or U-shaped groove sections which each encompass one side of the body of the inactive leaf sliding arm so that the body of the inactive leaf sliding arm between the two groove sections is stored. The body of the inactive leaf sliding arm is guided or held in the groove of the actuating element on both sides.

In one embodiment it can be provided that the control device interacts with the blocking device in that the control device transmits a movement to the blocking device via a transmission element, for example a push rod or push rod or a Bowden cable. The active leaf is blocked until the passive leaf reaches the closed position or is just before the closed position. For this purpose, the blocking device is preloaded in the blocking position, for example by an energy storage device, and stops the active leaf before it reaches its closed position. Via the interaction of the actuating element and the control device, the blocking device is activated by the control device in such a way that this pre-load causing the blocking position cancels and the closing movement of the active leaf is made possible. The cancellation of the blocking position is reversible, so that after the passive leaf is opened, the active leaf is blocked again before it reaches its closed position.

There are various possible structural designs for the blocking devices that are sufficiently known to the person skilled in the art from practice. For example, the blocking device of the active leaf can be designed as a clamping device, preferably a ball clamping device. This clamping device can preferably be on one in the slide rail A guided sliding element or other components of the sliding arm door closer on the moving leaf side act. It is essential that the blocking effect of the blocking device can be canceled by the control device on the stationary leaf.

An embodiment with a compact and less failure-prone structure results in that the blocking device and the control device are largely arranged within a slide rail, preferably enclosed by a housing of the slide rail.

A cooperation between the actuating element and the control device takes place in particular in the area of the closed position of the passive leaf. If the inactive leaf is closed or if the inactive leaf is brought into the closed position, the actuating element interacts with the control device in a certain angular range of the inactive leaf in order to release the blocking of the active leaf. This angular range can extend from shortly before reaching the closed position to reaching the closed position, preferably over an angular range of, for example, 20 ° up to 0 ° (closed position). When interacting, the sliding arm of the passive leaf door closer executes a reverse movement in this angular range, which is directed linearly along the slide rail. This linear movement actuates the release lever of the control device and the blocking of the active leaf is released.

Preferably, it can be provided in one embodiment that the control device has a bearing element and a triggering element and the actuating element moves the bearing element relative to the triggering element through the interaction with the control device, or that the actuating element, through the interaction with the control device, the triggering element relative to the bearing element shifts. So can the Movement of the actuating element can be used particularly effectively to release the blocking of the active leaf.

In a compact embodiment it can be provided that the bearing element guides the release element displaceably, in that the bearing element has opposite sliding surfaces and a guide section of the release element is guided displaceably between these sliding surfaces.

In one embodiment, it can preferably be provided that the release lever is designed as a two-armed lever which is rotatably mounted in the bearing element. The first arm of the two-armed control lever protrudes from the slide rail into the plane of rotation of the fixed leaf door closer and the second arm interacts directly or indirectly with the release element to release the blocking device. It is preferably provided that the second arm of the release lever acts on a run-up surface arranged on the release element, and acts upon this during pivoting so that the release element is displaced along the slide rail or relative to the bearing element.

The two-armed control lever can be rotatably mounted about a horizontally extending axis which preferably runs transversely to the longitudinal extension of the slide rail.

The two-armed release lever can be mounted in the bearing element, in particular, via bearing journals or via an axis. The bearing journals or the axle can be designed in one piece with the bearing element or the release lever, or be designed as separate components.

A particularly good mounting of the release lever can be achieved with an embodiment in which the horizontally running axis on which the two-armed lever is mounted extends through the bearing element into the wall area of the slide rail. A further improvement in the mechanical load-bearing capacity can be achieved in that the end sections of the horizontally running axis are each held in a receptacle arranged in or on the wall of the slide rail or are guided in a groove.

It can be provided that the control device has an energy storage device, preferably a spring, which preloads the release element so that the release element normally, i. H. without the action of the actuating element, the energy storage device is brought into an initial position. In the starting position, the blocking effect of the blocking device is restored, so that a closing movement of the active leaf is stopped.

For an embodiment that advantageously saves overall height, provision can be made for the actuating element to be arranged in alignment with the sliding arm of the stationary leaf door closer. The slide arm is usually designed as a flat component with a low overall height and is mounted in the installation space between the slide rail and a door closer housing. By arranging the actuating element in alignment with the slide arm, no additional installation space is required between the slide rail and the door closer housing and the closing sequence control can be made particularly compact. The arrangement of the actuating element in alignment with the plane defined by the sliding arm also includes designs in which the actuating element has a greater or lesser thickness than the sliding arm as long as an extension of the center line of the slide arm extends through the actuating element.

In particular, it can be provided in one embodiment that the actuating element is opened on the side facing the inactive leaf in order to grip the release lever.

The sliding arm of the passive leaf performs a combined movement, composed of a rotary movement about an axis running through the bearing pin of the sliding element and a linear movement running along the slide rail. The opening of the actuating element is arranged in such a way that when the passive leaf is closed, the opening as a result of the rotary movement through the opening directed towards the inactive leaf engages with the release lever of the control device.

A particularly simple assembly of the closing sequence control results when the actuating element is pre-equipped or prefabricated together with the sliding arm door closer at the factory.

The closing sequence control according to the invention can be used for double-leaf doors which are arranged, for example, in corridors in buildings. The closing sequence control can also be used for double-leaf fire protection doors, for example.

In the Figure 1 a double-leaf door with a closing sequence control 1 is shown. The two door leaves 11g, 11s are held in a fixed frame 16 via strips 15a, b, c, d and in the Figure 1 shown in closed position. The stationary frame 16 comprises an opening in a wall 17.

One leaf of the door is designed as an active leaf 11g and the other leaf of the door is designed as an inactive leaf 12s. The active leaf is an overturning active leaf and is normally opened to allow people to enter the door. The passive leaf is designed as a concealed leaf and normally remains closed. The passive leaf 12s is usually only opened when a wide passage is required.

Both door leaves 11g, 12s are provided with sliding arm door closers 2g, 3s located at the top, which act on the door leaves 11g, 12s in the closing direction. The sliding arm door closers 2g, 3s each have a housing mounted on the door leaves, in which a door closer mechanism with a closing spring is arranged, which acts on a door closer shaft 23g, 33s. As a force-transmitting linkage, a sliding arm 21g, 31s is connected to the door closer shaft 23g, 33s in a rotationally fixed manner and is guided over a sliding block 22g, 32s in a slide rail 4 mounted on the upper spar of the door frame.

The Figure 1 shows an assembly of the door closers on the opposite hinge, ie the opening direction of the two door leaves 11g, 12s extends into the plane of the drawing.

Like in the Figure 5 shown, the mechanism of the closing sequence control device 1 is accommodated in a concealed manner in the slide rail 4 and ensures that the two door leaves 11g, 12s always adhere to the correct closing sequence when closing.

In its closed position, the inactive leaf 12s interacts with the control device 5 to release the blocking device 6. This means that when the passive leaf comes into the closed position or is in the closed position, the braking effect of the blocking device 6 is canceled via the control device 5, and the active leaf can close.

The closing sequence control 1 comprises a control device 5 on the stationary leaf side and a blocking device 6 on the active leaf side. The control device 5 is arranged within the slide rail 4 in the area of the stationary leaf 12s and is connected to the blocking device 6 via a push rod 61.

The blocking device 6 stops the movement of the active leaf 11g before it reaches its closed position. To this end, the blocking device brakes the movement of the sliding arm on the active leaf side or the sliding block on the active leaf side in the slide rail 4. The active leaf 11g is stopped by the blocking device 6 in such a position that the movement of the passive leaf 12s is not hindered when it is closed.

The function and structure of the closing sequence control 1 is illustrated below using the illustrations of Figures 3 to 6 explained in more detail. The control device 5 comprises a bearing element 51 ( Fig. 3a ) and a Release element 55 ( Figure 3b ). A push rod 61 ( Fig. 1 ) connects the release element 55 with the blocking device 6 in order to control this depending on the position of the release element 55 relative to the bearing element 51 ( Fig. 5 ), ie to release or activate the blocking effect of the active leaf.

The bearing element 51 and the trigger element 55 are formed from a plastic. In order to avoid deformation of the plastic when it is installed in the slide rail 4, two plate elements 43a, 43b made of metal are used.

The bearing element 51 supports the release element 55 displaceably in that the bearing element 51 has two opposing sliding surfaces 51a and 51b, between which a guide element 55a of the release element is guided ( Fig. 5 ). Further, from the Figure 5 Upward and downward sliding surfaces that are not directly visible are provided to guide the release element 55 on the bearing element 51. As a result of this guide, the trigger element 55 slides exclusively on the bearing element 51 and has no common sliding surface with the slide rail 4. The trigger element therefore only slides on sliding surfaces of the friction partners plastic to plastic. This effectively prevents the plastic / metal material combination from creating a high frictional resistance.

During assembly, the release element 55 ( Figure 3b ) into the bearing element 51 ( Fig. 3a ) and both are inserted into the slide rail and fastened there ( Fig. 5 ). By moving the bearing element 51 along the slide rail, its exact position can be adjusted. The attachment of the bearing element 51 is now carried out via the pressure plate 43a, which is screwed against two square nuts inserted into the bearing element 51 by means of threaded pins and thus braced against the slide rail wall, in order to fix the bearing element 51 in the desired position within the slide rail 4 ( Fig. 5 ).

A second fastening plate 43b extends from slide rail wall to slide rail wall transversely to slide rail 4 in order to prevent the slide rail 4 from being pressed together when the door frame is firmly screwed. The fastening plate 43b also serves as a counter-bearing for the receiving area of the release lever 52.

The control device 5 is preloaded into the blocking position via an energy storage device designed as a spring 62, so that the closing movement of the active leaf 11g is blocked normally or when the passive leaf 12s is open ( Figure 6a ). The spring 62 is arranged between the bearing element 51 and the release element 55 and acts on the release element 55 in such a way that it blocks a closing movement of the active leaf 11g via the blocking device 6.

In the case of the assembly on the opposite side of the hinge, the geometric dimensions result in a special feature of the movement sequence of the sliders 22g, 32s ( Fig. 1 ). These do not perform a continuous movement, but rather reverse their direction of movement shortly before reaching the closed position of the respective door leaf.

In the representation of the Figure 1 the sliding block 32s of the door closer 3s on the stationary leaf side initially runs to the left during closing in the direction of the closing edge of the stationary leaf 12s. Just before reaching the final In the closed position, however, the sliding block 32s reverses its direction of movement and runs to the right to the hinge side of the inactive leaf 12s until the final closed position is reached. For the sliding block 22g on the active leaf side, the same applies with the opposite direction of movement.

The interaction of the sliding arm door closer 3s on the stationary leaf side with the control device 5 is illustrated below with reference to FIG Figures 2 to 6 explained in detail.

The Figure 2a shows the sliding arm 31s on the stationary leaf side with the actuating element 7 in a side view. The sliding arm 31s is rotatably and detachably connected at one end to an axis 33s of the door closer on the stationary leaf side. The area of the free end of the inactive leaf slide arm 31s lies opposite the end of the slide arm 31s connected to the door closer axis 33s and is assigned to the slide block 32s guided in the slide rail 4.

By opening and closing the stationary leaf 12s, the sliding arm 31s on the stationary leaf is moved within a plane of rotation D indicated by a dashed line, the sliding arm 31s performing a combined linear and rotary movement. The actuating element 7 is arranged in alignment with the body of the sliding arm 31s to save space. The actuating element 7 or the body 73 of the actuating element 7 is thus also arranged in the plane of rotation D.

A top view of the sliding arm 31s in various representations that differ from one another only by the position of the actuating element 7 is shown in FIG Figure 2b shown. In the bottom representation of the Figure 2b the actuating element 7 is released from the slide arm 31s. The Actuating element 7 is designed symmetrically with respect to its longitudinal axis, or the longitudinal axis of the sliding arm 31s, and can be used for right or left assembly. It can be in the position as in Figure 2b shown connected to the sliding arm 31s, or in a position rotated by 180 ° (In the bottom illustration of the Figure 2b indicated by arrows) are connected to the slide arm 31s. This means that the closing sequence control can be used universally, regardless of whether the fixed leaf of the double-leaf door is arranged on the right or left.

The actuating element 7 has a plug connection 74. It is attached to the free end of the inactive leaf sliding arm 31s and guided through the plug connection 74 on this. In the representations of the Figures 2b different positions of the actuating element on the slide arm are shown from bottom to top. The actuating element 7 can be fastened at any position on the inactive leaf sliding arm 31s within an adjustment range. The three in the representations of the Figure 2b The positions of the adjustment range shown show three possible positions within the adjustment range at 26mm, 36mm and 46mm. The adjustment range can preferably include a range from 20mm to 100mm. The adjustment range can also cover a larger area than 100mm. The upper limit of the adjustment range ultimately only depends on the length of the actuating element 7.

To connect the actuating element 7 to the sliding arm 31s, the latter has a C-shaped groove 72 which engages around the body of the sliding arm 38 on both sides. The C-shaped or U-shaped groove 72 has two groove sections 72a and 72b. These groove sections 72a and 72b are arranged opposite one another in such a way that the openings of the groove 72 each face one another. The distance between the two groove sections 72a and 72b is dimensioned so that the Body of the sliding arm 38 can be inserted between the two groove sections 72a and 72b. The distance between the two groove sections 72a and 72b corresponds to the dimensions of the sliding arm 31s in the region of its free end.

The actuation element 7 is fastened to the sliding arm 31s by means of a clamp connection which is inserted into the Figures 2c and 2d is shown in more detail. A bearing pin 35 rotatably connects the inactive leaf sliding arm 31s to the sliding block 32s. The bearing pin 35 has a collar 36 which forms a support surface 36 for the actuating element 7. The peripheral surface of the bearing pin has an external thread 37 which is screwed to the body of the inactive leaf slide arm 31s. Thus, the bearing pin also serves as a clamping screw. The actuating element 7 is clamped against the bearing surface 36 of the bearing pin 35 by this screw connection 37. This creates a non-rotatable connection between the bearing pin 35 and the actuating element 7 or inactive leaf sliding arm 31s.

The actuating element 7 has a roller 71 for actuating the control device 5 ( Fig. 2d ). The roller 71 is mounted on the actuating element 7 via a roller axis 71a. The roller axis is mounted in the plane of rotation D and thus in alignment with the inactive leaf sliding arm 31s. The roller 71 cooperates with a release lever 52 ( Fig. 3 and 4th ), in that the roller 71 grips and actuates this release lever 52 when the passive leaf 12s is closed. The roller 71 rolls on a rolling surface 54 of the release lever 52. The rolling surface 54 is attached to the free end of the release lever 52, which protrudes from the slide rail ( Fig. 3 and 4th ). A rounded surface of the rolling surface 54 compensates for tolerances and ensures that the roller 71 rolls smoothly. This enables an interaction between the actuating element 7 and the control device 5 that is as trouble-free as possible.

The release lever 52 is designed as a two-armed lever which is mounted rotatably about an axis 53 running horizontally and transversely to the longitudinal extension of the slide rail 4 ( Fig. 3 and 4th ). The release lever 52 is rotatably mounted with the axis 53 in the bearing element 51, as in the Figures 3a and 4a is shown. The ones in the Figures 4a to 4c and FIGS. 3a to 3c only differ in the type of mounting of the release lever 52. In FIGS Figures 3a to 3c the axis 53 is arranged completely within the bearing element 51, being in the in the Figures 4a to 4c The embodiment shown extends beyond the bearing element 51 into the wall area 41 of the slide rail 4 and is held there in receptacles 42a and 42b.

The design mode of operation of the release lever is also shown in the sectional view of FIG Figures 6a and 6b shown in more detail. Figure 6a shows the blocking position of the closing sequence control 1 when the release lever 52 is not actuated. Figure 6b shows an actuation position of the release lever 52 in which the blocking effect via the release element 55 is canceled.

The release lever 52 is designed as a two-armed release lever. It has a first arm 52a and an arm 52b extending at right angles thereto. The first arm 52a of the release lever 52 extends downward beyond the slide rail 4 into the plane of movement of the slide arm 31s on the stationary leaf side.

The second arm 52b of the release lever 52 interacts with the release element 55 in that the latter acts on a run-up slope in order to move the release element 55 relative to the bearing element 51. The course of the force or the course of the path can be optimized via the configuration of the run-up slope 56 and the second lever arm 52b.

The two-armed release lever 52 is actuated in that the actuating element 7 has an opening with a roller 71. This opening is open on the side facing the passive leaf 12s. As the sliding arm 32s on the standing leaf comes into the closed position, the opening pivots over the first arm 52a of the control lever 52.By reversing the movement of the sliding arm 32s on the standing leaf shortly before reaching the closed position, the control lever 52 is now pivoted over the actuating element 7 by the roller 71 being the first arm of the release lever 52 is actuated and rolls on the rolling surface 54 of the release lever. The inactive leaf slide arm 31s or the actuating element 7 moves a little along the slide rail 4 in the direction of the hinge side of the inactive leaf 12s and takes the first arm 52a of the release lever 52 with it, as in FIG Figures 6a and 6b is indicated by arrows. The second arm 52b of the control lever 52 now presses the release element 55 via the run-up bevel 56, so that this moves relative to the bearing element 51 along the slide rail 4 and releases the blocking effect of the blocking device 6 via the push rod 61.
