Description

[0001] The invention relates to a door closer system for a double-leaf door, wherein the door closer system comprises a first door closer for a fixed leaf of the door and a second door closer for an active leaf of the door, wherein the first door closer comprises a closing unit that can be arranged on the fixed leaf, a closing lever and a sliding block, wherein the sliding block is connected to the closing unit via the closing lever and is guided in a slide rail of the first door closer, wherein the door closer system further comprises a closing sequence control with a release unit, a transmission unit and a locking unit for blocking a closing movement of the second door closer, wherein the locking unit can be controlled via the transmission unit by the release unit as a function of an opening angle of the fixed leaf during an opening movement of the fixed leaf to block the closing movement of the second door closer.and wherein the release unit mechanically interacts with the first door closer. Furthermore, the invention relates to a double-leaf door with an active leaf and a fixed leaf, comprising a closer system with a first door closer for the fixed leaf and a second door closer for the active leaf.

[0002] Double-leaf doors are generally known in the art. They often consist of an active leaf and a fixed leaf, with the fixed leaf remaining closed during normal operation. Such double-leaf doors can be equipped with a door closer system, where each leaf has its own door closer. Since the fixed leaf must be fully closed before the active leaf completes its closing action, door closer systems for double-leaf doors are usually equipped with a closing sequence control. This is particularly important for fire doors to ensure reliable operation, especially the complete closure of both leaves in the event of a fire.

[0003] Common door closing sequence systems typically include a release mechanism that detects when the inactive leaf is opened, thereby preventing the active leaf from closing. These release mechanisms are usually located on a follower flap or on the closer lever of the inactive leaf's door closer. As a result, these release mechanisms are generally accessible and can be tampered with. Therefore, reliable locking of the active leaf's closing mechanism cannot always be guaranteed. Furthermore, such visible release mechanisms often detract from the overall appearance of the entire double-leaf door.

[0004] With a door closer featuring a slide rail, it can also occur that, at small door angles, the slide block performs a movement with a turning point when opening and closing the door, meaning that a certain section of the slide rail is traversed twice by the slide block. This can occur particularly with door closers mounted on the opposite side of the door leaf, although such behavior can also occur with other mounting types, depending on the specific door and door closer geometry. Triggering the closing sequence control solely via the stroke of the slide block is therefore not readily possible in the area of ​​the slide rail that is traversed twice.

[0005] It is therefore an object of the present invention to at least partially overcome the disadvantages of known door closer systems and known double-leaf doors of the prior art described above. In particular, it is an object of the present invention to provide a door closer system and a double-leaf door in which the protection of a release unit against unintentional external manipulation is improved, and in which, preferably, the triggering of a locking mechanism is possible even with a sliding block in the area of ​​the guide rail traversed twice.

[0006] The aforementioned problem is solved by the claims. In particular, the problem is solved by a closing system with the features of independent claim 1 and by a double-leaf door with the features of claim 15. Further features and advantages of the closing system and the double-leaf door according to the invention will become apparent from the dependent claims, the description, and the drawings.

[0007] According to the invention, the problem is solved by a door closer system for a double-leaf door, wherein the door closer system comprises a first door closer for a fixed leaf of the door and a second door closer for an active leaf of the door, wherein the first door closer comprises a closing unit that can be arranged on the fixed leaf, a closing lever and a sliding block, wherein the sliding block is connected to the closing unit via the closing lever and is guided in a slide rail of the first door closer, wherein the door closer system further comprises a closing sequence control with a release unit, a transmission unit and a locking unit for blocking a closing movement of the second door closer, wherein the locking unit can be controlled via the transmission unit by the release unit as a function of an opening angle of the fixed leaf during an opening movement of the fixed leaf to block the closing movement of the second door closer.and wherein the release unit mechanically interacts with the first door closer. The closer system according to the invention is characterized in that the release unit has a release element arranged inside the slide rail for releasably coupling the release unit and the transmission unit, wherein a sliding block end of the closer lever is rotatably connected to the sliding block and rotationally fixed to the release element, and the sliding block is arranged between the sliding block end and the release element.

[0008] The door closer system according to the invention is designed for a double-leaf door. For this purpose, the door closer system comprises a first and a second door closer, the first being for closing the inactive leaf and the second for closing the active leaf. At least the first door closer, preferably both door closers, are equipped with a slide rail in which a sliding block is slidably mounted. The sliding block is connected via a closer lever to a closing unit of the door closer, the closing unit comprising a mechanical, electromechanical, and / or hydraulic drive unit for initiating a closing action of the respective door leaf. The closing unit can be mounted directly on the door leaf, and the slide rail on the door head, preferably in a hinge-side mounting, alternatively also in a hinge-side mounting.

[0009] Furthermore, the door closer system according to the invention is equipped with a closing sequence control to ensure the safe and, in particular, complete closing of the double-leaf door even when the inactive leaf is open. A release unit of the closing sequence control is provided as part of the closing sequence control to detect an opening of the inactive leaf, in particular an opening that exceeds a predetermined or correspondingly set opening angle, hereinafter referred to as the release angle, and is designed to interact with the first door closer for this functionality. The release generated by the release unit is transmitted to a locking unit via a transmission unit, for example, mechanically via a push rod and / or a Bowden cable, or hydraulically, pneumatically, and / or by electrically and / or electronically transmitting the release information.Both the transmission unit and the locking unit are further elements of the locking sequence control.

[0010] When triggered, the locking unit prevents the active leaf from closing, for example, by interacting with the second door closer or by directly acting on the active leaf. Preferably, the locking unit only blocks the closing process above a predetermined or appropriately set closing angle of the active leaf; in other words, closing is still possible for opening angles greater than the closing angle. Equally preferred is the ability to allow any opening of the active leaf, regardless of whether the release unit has been triggered.

[0011] A key feature of the closing system according to the invention is that one of the essential elements of the release unit, namely a release element, is arranged inside the slide rail. "Inside the slide rail" in the context of the invention means, for example, that in the case of a substantially U-shaped slide rail, the release element is arranged between the two legs in the area where the two legs connect. This means that the release element is essentially concealed by the slide rail and thus protected from unintentional manipulation. Furthermore, this allows for a particularly attractive design of the entire closing unit, in which, in particular, the presence of the closing sequence control is not visible or at least only minimally so.

[0012] The release element is specifically designed for a detachable coupling between the release unit and the transmission unit. In other words, the release element transmits a release signal, which occurs at a specific opening angle—namely, the release angle—of the fixed leaf to the transmission unit, which in turn forwards the release signal to the locking unit. In other words, the release angle is the opening angle of the fixed leaf at which the locking sequence control is fully activated.

[0013] As described above, in particular when the closing system according to the invention is mounted opposite the hinges, the position of the sliding block in the slide rail alone is not sufficient as a trigger criterion to ensure that the closing process of the active leaf is blocked depending on an opening angle of the inactive leaf, since the movement of the sliding block has a turning point and thus a part of the slide rail is traversed twice during the opening process of the inactive leaf.

[0014] For this reason, according to the invention, the release element is coupled to the closer lever of the first door closer, the angle of rotation of which, for example measured relative to the sliding block, is directly and unambiguously correlated with an opening angle of the fixed leaf. The closer lever extends from its closing end, where it is mechanically connected to the closing unit, to an opposite sliding block end, where it interacts with the sliding block. For this purpose, the closer lever is rotatably connected to the sliding block at the sliding block end, but simultaneously also rotationally fixed to the release element.

[0015] The rotatable connection with the sliding block allows the sliding block to move linearly along the guide rail, especially when the angle between the closer lever and the sliding block changes continuously during the opening process of the fixed leaf. Simultaneously, the rotationally fixed connection of the closer lever to the release element ensures that the angle of the closer lever, which is uniquely correlated with the opening angle of the fixed leaf, is directly transferred to the position, orientation, and rotation of the release element. In other words, the position, orientation, and rotation of the release element are also uniquely correlated with the opening angle of the fixed leaf.

[0016] Furthermore, according to the invention, the sliding block is located between the release element and the closing lever, in particular between the release element and the sliding block end of the closing lever. The closing lever is arranged outside the slide rail, particularly, for example, to allow the pivoting and rotating movements associated with the movement of the fixed leaf to be carried out unhindered. At the same time, the sliding block is arranged at least substantially within the slide rail, at least to the extent that its guidance within the slide rail can be reliably ensured. Since, according to the invention, the release element and the sliding block end of the closing lever are arranged on different, opposite sides of the sliding block, it can be ensured particularly easily that the release element, and thus at least substantially the release unit, is located inside the slide rail.All the aforementioned advantages and associated benefits can thus be achieved particularly easily.

[0017] Furthermore, the closing system according to the invention can be designed such that a shaft is fixedly attached to the end of the sliding block in a rotationally fixed manner, the shaft passing through a through-bearing opening in the sliding block, and the release element is then arranged on the shaft in a rotationally fixed manner. The shaft, which is fixedly attached to the end of the sliding block of the closing lever, makes it possible to provide both of the aforementioned properties of the closing system according to the invention in a particularly simple way with a single component. Firstly, the rotatable mounting of the sliding block at the end of the closing lever is made possible by the shaft passing through a bearing opening in the sliding block.On the other hand, the shaft on the side of the sliding block facing away from the closing lever still provides a component that is rotationally fixed to the closing lever, so that both the rotationally fixed connection of the release element to the closing lever and the positioning of the sliding block between the closing lever and the release element can be achieved.

[0018] Furthermore, the closing system according to the invention can be characterized in that the transmission unit has a coupling mechanism arranged stationary in the slide rail for releasable coupling with the release element, wherein the coupling mechanism can be releasably coupled to the release element depending on a rotational position of the release element, and when coupled to the release element, initiates a movement of the release element into the transmission unit to actuate the locking unit. A stationary arrangement of the coupling mechanism within the meaning of the invention means in particular that the coupling mechanism as a whole is arranged or positioned stationary in the slide rail, wherein, for example, at least one bearing axis of an element of the coupling mechanism is stationary and thus fixed in the slide rail, but further elements of the coupling mechanism can move relative to this stationary bearing axis.For this purpose, the coupling mechanism is specially designed so that it can be arranged or positioned in the guide rail for the described installation. Overall, the coupling mechanism establishes the mechanical connection between the release element of the release unit and the transmission unit, which, according to the invention, is designed to be detachable. Because the coupling depends on the rotational position of the release element, the rotational position of the closing lever, and thus the opening angle of the fixed leaf, is automatically taken into account in a particularly simple manner. The transmission of a release signal from the release unit via the transmission unit to the locking unit can therefore also be dependent on the opening angle of the fixed leaf.This can be particularly advantageous when the closer system is mounted opposite the hinge side, since, as already explained above, the sliding block performs a movement with a turning point and therefore a dependence of the coupling solely on a position of the sliding block in the slide rail is insufficient, but in the mounted state of the closer system, an opening angle of the fixed leaf clearly defines a position of the sliding block in the slide rail together with a rotational position of the release element.

[0019] Furthermore, the closing system according to the invention can be further developed by making the opening angle of the fixed leaf adjustable. This angle, at which the coupling mechanism is coupled to the release element and thus the locking unit is actuated when the closing system is mounted, is determined by the arrangement position of the coupling mechanism in the guide rail and / or by the relative alignment of the release element to the closing lever. The arrangement position, in particular, defines the position of the slide block at which the release element, which moves with the slide block, and the coupling mechanism can interact. A relative alignment of the release element to the closing lever, in turn, influences the actual orientation of the release element relative to the slide block, the guide rail, and the coupling mechanism.This allows, in particular, the trigger angle—that is, the opening angle of the inactive leaf at which the trigger unit activates the closing sequence control—to be adjusted. Different configurations of double-leaf doors, especially varying widths of both the inactive and active leaves, as well as asymmetrical door divisions, require adjusted trigger angles and can therefore be taken into account.

[0020] In a further development, the closing system according to the invention can also include an arrangement position such that, in the mounted state, the opening angle of the fixed leaf, which is thereby set for actuating the locking unit, is 5° or less. In this way, even with a particularly small opening angle of the fixed leaf, triggering of the closing sequence control and thus blocking of the closing movement of the active leaf is possible. In other words, particularly small opening angles of the fixed leaf can be defined and selected as the trigger angle. This further improves the assurance that the closing process of the fixed leaf is completed before the closing of the active leaf.

[0021] The closing system according to the invention can also be designed as a single-armed release lever with a release pin, wherein the release lever is rotationally fixed to the closing lever at one end and carries the release pin at the other end, and wherein the coupling mechanism has a drive lever designed as a single-armed lever, wherein the drive lever has a rail end and an opposite drive end, and is fixedly but rotatably mounted at its rail end and has a U-shaped drive receptacle open towards the drive end, and wherein the release pin engages in the drive receptacle for releasable coupling of the release element with the transmission unit. Levers, especially single-armed levers, are mechanically very simple, but therefore also very reliable elements, as are pins and the receptacles into which these pins engage.

[0022] As an alternative to the design with a release pin on a single-arm release lever and with a single-arm drive lever with a drive receptacle, other kinematically equivalent transmission elements are also conceivable, which allow a detachable coupling between the release element and the coupling mechanism.

[0023] Furthermore, the interaction of the release pin on the release lever with the U-shaped drive receptacle on the drive lever enables the release mechanism of the coupling as described in the invention. The release lever, which is preferably fixedly mounted on a shaft located at the sliding end of the closer lever, rotates with the closer lever when the fixed leaf is opened, thereby also moving the release pin, particularly in a superimposed movement consisting of the rotational movement of the release lever and the sliding movement of the sliding block. At the location of the coupling mechanism, the positions assumed by the release pin and the drive receptacle are preferably coordinated such that the release pin engages in the drive receptacle, thus coupling the release unit and the transmission unit. The release signal can then be transmitted to the locking unit.The position of the drive lug is determined primarily by the bearing axis at the end of the drive lever's rail. This bearing axis is fixed in the slide rail and thus determines the position of the entire coupling mechanism within the slide rail. Furthermore, the direction in which the drive lever extends from the closing end to the drive lug is also important for the closing sequence control and is preferably adjustable accordingly.

[0024] According to a further developed embodiment of the closing system according to the invention, the follower receptacle can also be provided with two legs of different lengths. As already explained several times above, the closing system according to the invention can be used in a hinge-side mounting. Therefore, it is conceivable that the release pin, corresponding to the movement of the sliding block near its reversal point, slides past the coupling mechanism and, in particular, the follower receptacle twice: once at the desired release angle and once at an opening angle of the fixed leaf that does not correspond to the release angle. In order to prevent the release pin from striking or even engaging with the follower receptacle at this opening angle that does not correspond to the release angle, it is advantageous to have the two legs of the follower receptacle of different lengths.In particular, for example, after a triggering event has already occurred, the trigger lever may be pivoted, so that the trigger pin would only strike one of its two legs as it moves along the guide rail. Shortening this leg accordingly prevents this, thus reliably preventing the trigger pin from striking the trigger and, in particular, a faulty retraction of the triggering event by the trigger pin engaging the trigger receptacle again.

[0025] The closing system according to the invention can also be characterized in that the coupling mechanism has an intermediate lever and the transmission unit has a push rod mounted to be linearly displaceable along the slide rail, wherein the intermediate lever is rotatably mounted at the drive end and coupled to the push rod, preferably rotatably coupled, and wherein, in particular, the drive receptacle is designed in a trough-like manner. In the assembled state, the release unit is usually located in the area of ​​the inactive leaf, while the locking unit is located in the area of ​​the active leaf. Push rods have proven particularly suitable for bridging the distance between these two units, as they require little installation space and can nevertheless transmit forces and thus a release event safely and reliably.By means of an intermediate lever, which is rotatably mounted at both the drive end and a corresponding end of the push rod, the connection of such a push rod to the coupling mechanism with drive lever described above can be made particularly simple and secure. In particular, the intermediate lever allows the rotary movement of the drive lever to be converted into the linear movement of the push rod.

[0026] To enable the greatest possible stroke while simultaneously minimizing the required installation space, the intermediate lever is articulated to the drive end of the drive lever. This can be achieved by a recessed design of the drive receptacle. "Recepted" in the context of the invention means that the U-shaped drive receptacle, parallel to the plane in which the "U" of the U-shaped drive receptacle is arranged, is closed on one side by material of the drive lever, but remains uncovered on the opposite side. From this uncovered side, the release pin can then engage the drive receptacle unhindered, while a bearing for the intermediate lever can be arranged on the now exposed material at the drive end of the drive lever.

[0027] In a further embodiment, the closing system according to the invention can be characterized in that the release unit and the coupling mechanism, preferably the release unit and the transmission unit, are arranged completely within the slide rail. According to the invention, "arranged completely within the slide rail" means that no elements of the release unit and the coupling mechanism, preferably the release unit and the entire transmission unit, are located outside the volume enclosed by the slide rail. For example, in the case of a substantially U-shaped slide rail, all corresponding elements are arranged in the recess formed by the slide rail, which is also at least substantially U-shaped. This avoids the additional installation space required for the arrangement of the release unit and the coupling mechanism, in particular the entire transmission unit.Furthermore, arranging the components entirely within the guide rail increases protection against unintentional and / or even unauthorized operation, as the relevant elements are difficult or even impossible to access. Finally, such a concealed arrangement is also more visually appealing than if components were visible protruding outside the guide rail.

[0028] Furthermore, the closing system according to the invention can also include an electrically controlled hold-open device for holding the active leaf in place, wherein the hold-open device is arranged in and / or on the guide rail in the area of ​​the release unit and can be coupled to the transmission unit for locking the active leaf. Such an electrically controlled hold-open device is also referred to as an E-hold-open device. In the following, the terms hold-open device and E-hold-open device are used synonymously. A hold-open device provides the functionality that a door leaf, in this case the active leaf, is held open and thus deliberately kept open, optionally for a limited time or, at least theoretically, indefinitely.This can be advantageous, for example, for doors, especially fire doors, which are intended to be barrier-free during normal operation and are only intended or required to be closed in case of danger, for which the closing units of the closing system according to the invention can be used.

[0029] As described in detail above, the closing sequence control of the closing system according to the invention allows the active leaf to be selectively locked, thus preventing it from closing. However, this essentially constitutes the same functionality as a hold-open device. By coupling the hold-open device with the transmission unit, the transmission unit, and therefore also the locking unit coupled to it, can be used and controlled by the hold-open device. In other words, a separate locking unit and its control system provided solely for the hold-open device are no longer necessary.

[0030] The term "holding device" as used in the invention refers only to that group of components which differs from the components of the closing sequence control, and in particular to a pulse generator for triggering the holding of the active leaf. Such a pulse generator can, for example, be an electromagnet, especially a solenoid. Unnecessary components and the associated space requirements and costs can be avoided.

[0031] The holding device is arranged in and / or on the slide rail in the area of ​​the release unit and can also be coupled to the transmission unit there. Thus, in this embodiment of the closing system according to the invention, the components of the transmission unit and the locking unit used for transmitting a control signal can essentially be used by both the closing sequence control and the holding device.

[0032] Furthermore, the closing system according to the invention can be further developed by arranging the holding device completely within the guide rail. In this embodiment, the holding device is not visible from outside the guide rail and, in particular, is not accessible or only very difficult to access, thus protecting it against unwanted or even unauthorized manipulation. Besides a particularly attractive appearance, this also prevents or at least significantly hinders unintentional, unwanted, or even unauthorized activation of the holding mechanism of the active leaf. Improved protection against vandalism can thus be achieved.

[0033] According to a further development of the closing system according to the invention, it can also be provided that when the hold-open device is activated, the transmission unit cancels the transmission of a release signal generated by the release unit. Even when the active leaf is already held in place by the hold-open device, the inactive leaf can still be opened, which automatically triggers the locking unit via the release unit of the closing sequence control. However, since the active leaf is already held in place and thus a closing process of the active leaf is prevented, this additional control, because it uses the transmission unit and the locking unit to lock the active leaf just like the hold-open device, could lead to a mutual and, in particular, negative interference between the hold-open device and the closing sequence control.This source of error can be avoided by canceling the transmission unit's forwarding of a trigger signal from the release unit when a locking device is activated.

[0034] The closing system according to the invention can also be further developed by coupling the intermediate lever to the push rod by abutting a projection of the intermediate lever against a stop end of an elongated hole in the push rod, wherein, when the locking device is activated, the push rod is displaced and thus the impact of the projection on the stop end is released. In this particular embodiment of the closing system according to the invention, both a push rod as part of the transmission unit and a locking device are present. Both the locking device and the coupling mechanism of the transmission unit displace the push rod to actuate the locking unit and thereby prevent the closing of the active leaf. This displacement of the push rod occurs in the same direction in both cases, usually in the direction of the active leaf.By designing the coupling between the intermediate lever and the push rod via a slot in the push rod and a projection, preferably pin-shaped, on the intermediate lever, it is possible to ensure particularly simply, reliably, and especially reversibly that when the locking device is activated, which also moves the push rod, the projection no longer abuts the end of the slot, thus preventing the transmission of a release generated by the trigger unit through the transmission unit. When the locking device is deactivated, the push rod preferably moves back to its initial position, restoring the projection's abutment against the end of the slot. The transmission is thereby stopped.

[0035] According to a further development, the closing system according to the invention can also be provided with a spring-loaded projection of the intermediate lever towards the stop end. This makes it particularly easy to ensure that, when the locking device is deactivated, the projection on the intermediate lever again abuts the stop end of the elongated hole in the push rod. This increases the operational reliability of the closing system according to the invention, especially the closing sequence control.

[0036] Furthermore, the problem is solved by a double-leaf door with an active leaf and a fixed leaf, comprising a door closer system with a first door closer for the fixed leaf and a second door closer for the active leaf. The double-leaf door according to the invention is characterized in that the door closer system is designed according to the invention. All the advantages described above with regard to a door closer system according to the invention can thus also be provided by a double-leaf door according to the invention that incorporates the door closer system according to the invention.

[0037] The invention is described below with reference to the figures. Elements with the same function and mode of operation are each provided with the same reference numerals in the figures.

[0038] They show schematically: Fig. 1 An embodiment of the double-leaf door according to the invention, Fig. 2 An embodiment of elements of the closing system according to the invention during an opening of the fixed leaf at a first opening angle of the fixed leaf, Fig. 3 The closing system of Fig. 2 at a second opening angle of the fixed leaf, Fig. 4 The closing system of Fig. 2 at a third opening angle of the fixed leaf, Fig. 5 The closing system of Fig. 2 at a fourth opening angle of the fixed leaf, Fig. 6The closing system of Fig. 2 at a fifth opening angle of the fixed leaf, Fig. 7. An embodiment of elements of the closing system according to the invention comprising a holding device, Fig. 8. The closing system of Fig. 7 upon triggering by opening the fixed leaf, and Fig. 9The closing system of Fig. 7 when the locking device is activated.

[0039] Fig. 1Figure 1 shows a double-leaf door 200 according to the invention, comprising a fixed leaf 210 and an active leaf 220. The door 200 is further equipped with a closing system 100 according to the invention. A follower flap 104 ensures that when the fixed leaf 210 is opened, the active leaf 220 is also pushed open.

[0040] The door closer system 100 has, in particular, a first door closer 110 for the fixed leaf 210 and a second door closer 120 for the active leaf 220. As shown, the entire door closer system 100 can be arranged in a hinge-side mounting on the door 200.

[0041] In particular, the first door closer 110, preferably and as shown, both door closers 110, 120, is / are equipped with a slide rail 132 in which a slide block 134 is slidably mounted. As shown, preferably a single, continuous slide rail 132 can be provided for both door closers 110, 120. Alternatively, two separate slide rails 132 can also be used for the two door closers 110, 120, for example, if the resulting freed-up installation space is needed for additional components, such as a smoke detector. The slide block 134 is connected via a closer lever 140, the end 142 of which is rotatably connected to the slide block 134, to a closer unit 130 of the first door closer 110, which is arranged on the door leaf of the fixed leaf 210.

[0042] Furthermore, the door closer system 100 according to the invention is equipped with a closing sequence control 10. This closing sequence control 10 ensures that when the fixed leaf 210 is open, the closing process of the active leaf 220 is blocked and thus stopped, so that a correspondingly executed closing process of the fixed leaf 210 is not obstructed and can be completed in its entirety. For this functionality, the closing sequence control 10 has a release unit 20 coupled to the first door closer 110, a transmission unit 30, and a locking unit 60. The locking unit 60 is provided for the actual locking of the second door closer 120, with the transmission unit 30 transmitting a release of the closing sequence control 10 by the release unit 20, in particular triggered by the opening of the fixed leaf 210 beyond a release angle, to the locking unit 60.

[0043] In the Figs. 2 to 6The release unit 20 and part of the transmission unit 30 of the closing sequence control 10 of the closing system 100 according to the invention are shown in particular. The illustration shows a mounted state of the closing system 100 on a double-leaf door 200, especially in the area of ​​the inactive leaf 210 (not shown, see figure). Fig. 1 ). The Figs. 2 to 6 Each figure shows a state of the closing sequence control 10 during an opening process of the fixed leaf 210, whereby the opening angle of the fixed leaf 210 continuously increases. In particular, this triggers the closing sequence control 10, the execution of which is described in relation to the Figs. 2 to 6 is described.

[0044] The Figs. 2 to 6 They will therefore be described together below, with each description being discussed separately. In all Figs. 2 to 6Figures A and B are shown, depicting the identical state of the closing system 100. Both figures A and B show a top view inside the slide rail 132, with figure A showing a top view of visible components and figure B showing a sectional view at the level of a drive receptacle 56.

[0045] Fig. 2 Figure 1 shows a state of the closing system 100 according to the invention, in particular the release unit 20 and essential parts of the transmission unit 30 of the closing sequence control 10, at the beginning of an opening process of the fixed leaf 210. At this point, the fixed leaf 210 is still completely closed, or at least the opening angle of the fixed leaf 210 is still close to 0° and thus very small. As shown, the release unit 20 and the illustrated parts of the transmission unit 30, in particular the entire transmission unit 30, are completely arranged in the guide rail 132.

[0046] On the closing lever 140 of the first door closer 110, a shaft 144 is fixedly mounted at its sliding block end 142. This shaft 144 passes through a continuous bearing opening 136 in the sliding block 134. This rotatably couples the sliding block 134 to the closing lever 140. Simultaneously, a release element 22 of the release unit 20, designed as a release lever 24, is fixedly mounted on the shaft 144. In particular, this arrangement is such that the sliding block 134 is located between the closing lever 140 and the release lever 24. This allows the release unit 20 to be located inside the slide rail 134, thereby preventing or at least hindering unintentional or even unauthorized manipulation of the closing sequence control 10.

[0047] The rotationally fixed arrangement transmits the rotation angle of the closing lever 140, and thus indirectly the opening angle of the fixed leaf 210, to the release lever 24. This enables the closing sequence control 10 to be triggered depending on the opening angle of the fixed leaf 210.

[0048] In the illustrated embodiment, the release lever 24 has a release pin 26 for the release mechanism mentioned above, which is arranged at one end of the release lever 24 opposite the shaft 144. When the fixed wing 210 is opened, this release pin 24 performs a combined movement: firstly, a rotational movement around the shaft 144, and secondly, a sliding movement along the guide rail 132.

[0049] For a particularly detachable coupling of the release unit 20 and the transmission unit 30, the transmission unit 30 now has a coupling mechanism 40, which is fixedly arranged as a whole in the guide rail. An arrangement position 42 of the coupling mechanism 30 in the guide rail 132 can be used, in particular, to define a release angle, i.e., an opening angle of the fixed leaf 210 at which the release of the closing sequence control 10 is fully completed. In the illustrated embodiment, this release angle is less than 5°.

[0050] The coupling mechanism 40 has, in particular, a drive lever 50, the end of which 52 of which acts as a fixed bearing point in the slide rail 132, defining the arrangement position 42 of the coupling mechanism 40. Furthermore, an intermediate lever 44 of the coupling mechanism 40 is pivotally connected to the opposite drive end 54, and this intermediate lever is in turn rotatably connected to a push rod 32 of the transmission unit 30.

[0051] When the closing sequence control 10 is triggered, the release lever 24 pivots the driver lever 50, which in turn moves the push rod 32 via the intermediate lever 44 and ultimately the locking unit 60 (see Fig. 1 ) to block the closing movement of the swing wing 220 (see Fig. 1) activated. To accomplish this, the drive lever 50 has a U-shaped drive receptacle 56 that is open towards its drive end 54. As can be seen in the comparison of Figures A and B, this drive receptacle 56 is designed in a trough-like shape, so that a rotatable bearing of the intermediate lever 44 can be provided at the drive end 54. In the illustrated embodiment, the release pin 26 of the release unit 20 engages in this drive receptacle 56.

[0052] The triggering itself occurs when the fixed wing 210 is opened. This is in Fig. 3 shown. In comparison to Fig. 2The sliding block 134 was moved in the slide rail 132, and the closing lever 140, and thus automatically the release lever 24, was pivoted slightly. In particular, the sliding movement caused the release pin 26 to pivot the drive lever 50 about its fixed bearing at the rail end 52. This pivoting was transmitted to the push rod 32 via the intermediate lever 44, whereby the pivoting of the drive lever 50 was converted into a linear displacement of the push rod 32. Fig. 3 The figure shows the moment when the release pin 26 just leaves the follower receptacle 56, thus completing the triggering of the closing sequence control 10. This occurs particularly even at small opening angles of the fixed leaf, preferably at opening angles of less than or equal to 5°.

[0053] Due to the U-shaped design of the drive receptacle 56, the release pin 26 can be positioned as shown in Fig. 3As shown, the drive lever 56 leaves the drive receptacle. With an even greater opening angle of the fixed leaf 210, there is no longer any coupling between the release pin 26 and the drive receptacle 56. In other words, the coupling between the release unit 20 and the transmission unit 30 is a disengageable coupling. With a further displacement of the sliding block 134 in the guide rail 132, the drive lever 50 remains in its pivoted position, as exemplified in Fig. 4 depicted.

[0054] As already mentioned Fig. 1 The closing system 100 according to the invention can be arranged in a hinge-side mounting on the double-leaf door 200. This gives the movement of the sliding block 134 in the slide rail 132 a turning point, which is approximately in Fig. 4 shown.

[0055] In Fig. 5A further continuation of the opening movement of the fixed leaf 210 is now shown, whereby the sliding block 134 moves back in the sliding rail 132. In particular, in Fig. 5 The opening angle of the fixed leaf 210 is shown at which the sliding block 134 in the sliding rail 132 assumes the same position as when the coupling between release unit 20 and transmission unit 30 is released, cf. Fig. 3However, due to the larger opening angle of the fixed leaf 210, the position of the release pin 26 is now changed, thus preventing unwanted re-engagement of the release pin 26 into the follower receptacle 56. Additionally, the two legs 58 of the U-shaped follower receptacle 56 are of different lengths. The shorter leg 58 is, as shown, preferably positioned closer to the displacement path of the release pin 26, thereby preventing the aforementioned unwanted re-engagement with even greater certainty. At the same time, the longer leg 56 ensures sufficiently long contact between the release pin 26 and the follower receptacle 56 when the closing sequence control 10 is triggered.Furthermore, the different lengths of the legs 56 ensure that during a closing process the release pin 26 engages in the follower receptacle 56, thus preparing for a triggering of the closing sequence control 10 during the next opening process of the fixed leaf 210.

[0056] The sliding block 134 can be moved freely in the sliding rail 132 until it reaches its end position when the fixed leaf 210 is fully open, as shown in Fig. 6 shown. This end position can be determined by a user's request to open the door, but is fundamentally determined by system- and / or environment-dependent conditions of the double-leaf door 200 according to the invention. No further interaction takes place between the release unit 20 coupled to the fixed leaf 210 and the coupling mechanism 40 used to transmit the release signal.

[0057] In the Figs. 7 to 9A further developed embodiment of the closing system 100 according to the invention or of the double-leaf door 200 according to the invention is shown, in which the with reference to Figs. 2 to 6 The described closing system 100 is additionally equipped with an electrically controlled hold-open device 102. However, equipping it with a hold-open device 102 is generally possible and not limited to this embodiment of the closing system 100 according to the invention.

[0058] This shows Fig. 7 the closing system 100 with closed fixed leaf 210, Fig. 8 upon triggering of the closing sequence rule 10, and Fig. 9 when the locking device 102 is activated. Again, in all Figs. 7 to 9Two figures, A and B, are shown, depicting the identical state of the closing system 100. Both figures, A and B, show a top view inside the slide rail 132, with figure A showing an actual view of all components, while figure B shows a sectional view at the level of a drive receptacle 56. Figs. 7 to 9 They will therefore be described together below, with each presentation being discussed separately.

[0059] In relation to Fig. 7 The differences between the illustrated embodiment of the closing system 100 and that of the Figs. 2 to 6 described. Regarding the unchanged and partially undescribed elements of the closing system 100, reference is made to the preceding description of the Figs. 2 to 6 referred.

[0060] As shown, the closing system 100 additionally includes a holding device 102, which is preferably arranged entirely within the slide rail 132. The holding device 102 can, for example, comprise a switchable electromagnet, in particular a solenoid 106. Alternatively, other suitable electrical actuators are also conceivable. In the illustrated embodiment of the closing system 100, the push rod 32 of the transmission device 30 is extended in the direction of the holding device 102 and has a stop plate 38 for interacting with the solenoid 106 of the holding device 102.

[0061] Another difference is that the intermediate lever 44 is no longer rigidly connected to the push rod 32, but instead abuts a stop end 36 of an elongated hole 34 in the push rod 32 with a projection 46. In other words, the intermediate lever 44 is no longer rigidly, but detachably, coupled to the push rod 32. Preferably, the projection 46 of the intermediate lever 44 is spring-loaded in the direction of the stop end 36. This ensures that when the lifting magnet 106 is deactivated, the projection 46 abuts the stop end 36, thus guaranteeing the functionality of the closing sequence control 10.

[0062] This configuration results in the closing sequence control 10 being superior to the hold-open device 102. When the closing sequence control 10 is triggered, as in Fig. 8As shown, the functionality of the closing sequence control 10 can be provided unimpeded by the hold-open device 102. The projection 46 abuts the stop end 36, and the push rod 32 is moved to transmit the triggering of the closing sequence control 10, and in particular, is only moved back when the inactive leaf 210 is closed. The aforementioned stop plate 38 is lifted away from the hold-open device 102. For the further processes and properties of the closer system 100 and in particular the closing sequence control 10, reference is made to the above description regarding the Figs. 2 to 6 referred.

[0063] In Fig. 9 The holding device 102 is activated. The lifting magnet 106 is extended, which moves the stop plate 38. This moves the entire push rod 32, thereby activating the locking unit 60 of the closing sequence control 10 and the active leaf 220 (see figure). Fig. 1) is fixed. In other words, a closing action of the active leaf 220 is blocked and thus prevented. Simultaneously, when the inactive leaf 210 is closed, the projection 46 is lifted from the stop end 36. When the inactive leaf 210 is opened, the spring relaxes, the projection 46 moves towards the stop end 36 and finally strikes it, remaining in this position. This allows a release generated by the release unit 20 to be transmitted by the transmission unit 30, even when the hold-open device 102 is active. This prevents the hold-open device 102 from adversely affecting the closing sequence control 10. In other words, the spring tension of the projection 46 towards the stop end 36, as shown, ensures that when the hold-open device 102 is deactivated and the push rod 32 returns to its position, the projection 46 is held in the correct position. Fig. 7The displayed position returns, and any possible triggering of the closing sequence rule 10 is retained. Reference sign
