Description

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

[0002] Double-leaf doors are generally known in the art. Often, the double-leaf door is designed to have a moving leaf and a passive leaf, with the passive leaf remaining closed during normal door operation. Such double-leaf doors can be equipped with a closer system, with each door leaf assigned a door closer of the closer system. Since, for the door to fully close, the passive leaf must be fully closed before the moving leaf completes its closing process, closer systems for double-leaf doors are usually equipped with a closing sequence control. This is fundamentally important, for example, for fire doors to ensure safe operation, particularly in the event of a fire, by ensuring that both door leaves close completely.

[0003] Common door sequence controls usually consist of a trigger unit, a transmission unit, and a locking unit. The trigger unit detects the opening of the passive leaf and triggers the door sequence control, which is then forwarded by the transmission unit to the locking unit, which ultimately blocks the active leaf from closing.

[0004] In principle, closer systems are known in the prior art that feature a closing sequence control, i.e. a locking process of the active leaf in the closing direction when the passive leaf opens. In known closer systems that have a hydraulic lock in the active leaf door closer, a Bowden cable is usually used to implement the closing sequence control. However, such a cable pull has the disadvantage that it can become worn out and thus lengthened over the course of use. Furthermore, the Bowden cable may break due to the very high actuation or operating forces that can occur in certain situations. The free transition area between the guide rail and the door closer poses the risk of damage from vandalism and entrapment in the system. The movement of the leaf can lead to malfunctions / false activations due to this moving section.For this reason, a safe function of the closing sequence control, and thus of the entire closing system, cannot be guaranteed over the entire operating and service life.

[0005] Furthermore, the Bowden cable must transmit the entire force required for the locking unit. This can place high demands on the release unit, for example, in terms of its stability or available force development. Furthermore, the position of the active leaf can have a significant influence on the kinematics of the locking process, which cannot be compensated for by the Bowden cable, or can only be inadequately compensated.

[0006] It is therefore an object of the present invention to at least partially remedy the above-described disadvantages of known closer systems and of known double-leaf doors of the prior art. In particular, the object of the present invention is to create a closer system and a double-leaf door in which, in a closing sequence control, the transmission of a triggering action to a locking unit is improved over the entire operating period and / or across the entire opening angle range of the active leaf, in particular in which the influence of a position of the active leaf on the closing sequence control of the closer system is minimized, preferably eliminated.

[0007] The above object is achieved by the patent claims. In particular, the object is achieved by a locking system having the features of independent claim 1 and by a double-leaf door having the features of claim 15. Further features and advantages of the locking system according to the invention and of the double-leaf door according to the invention emerge from the subclaims, the description, and the drawings.

[0008] According to the invention, the object is achieved by a closer system for a double-leaf door, wherein the closer system comprises a first door closer for a fixed leaf of the door and a second door closer for a moving leaf of the door, wherein the second door closer comprises a closer unit that can be arranged on the moving leaf, a closer lever, and a sliding block, wherein the sliding block is connected to the closer unit via the closer lever and guided in a slide rail of the second door closer, wherein the closer lever has a sliding block end connected to the sliding block and a closer end connected to the closer unit, wherein the closer system further comprises a closing sequence control with a trigger unit, a transmission unit, and a locking unit for locking a closing movement of the second door closer,and wherein the locking unit can be controlled via the transmission unit by the triggering unit depending on the opening angle of the inactive leaf. The closer system according to the invention is characterized in that the transmission unit has at least one rail section and a closer section coupled thereto, wherein the rail section interacts with the triggering unit and is arranged at least partially in the slide rail, and the closer section interacts with the locking unit and is arranged at least partially from the sliding block end to the closer end along the closer lever of the second door closer, and wherein the locking unit is arranged on and / or in the closer unit of the second door closer.

[0009] The closer system according to the invention is intended for a double-leaf door. For this purpose, the closer system comprises the first and second door closers, wherein the first door closer is provided for closing the inactive leaf and the second door closer is provided for closing the active leaf. At least the second door closer, preferably both door closers, are equipped with a slide rail in which a sliding block is slidably mounted. The sliding block is rotatably connected to one sliding block end of a closer lever, which in turn is rotatably connected with its opposite closing end to a closer unit of the door closer. The closer unit has a mechanical, electromechanical and / or hydraulic drive unit for driving a closing process of the corresponding door leaf, transmitted to the door leaf by the above-described arrangement with the closer lever.Depending on the design, the second closer unit provided for the active leaf preferably has corresponding components for blocking a closing movement of the active leaf, for example a hydraulic blocking valve in the case of a door closer with a hydraulic drive unit. The closer unit can be arranged directly on the door leaf, the slide rail on the door lintel, preferably in a hinge-opposite installation.

[0010] In particular, the sliding block is motion-coupled to the active leaf. Moving the sliding block along the slide rail opens or closes the active leaf. The sliding block can be moved along the slide rail in an opening direction or in an opposite closing direction. If the sliding block is moved in the opening direction, the active leaf opens. If the sliding block is moved in the closing direction, the active leaf closes.

[0011] Furthermore, the closer system according to the invention is equipped with a closing sequence control to ensure secure and, in particular, complete closing of the double-leaf door even after the inactive leaf has been opened. A trigger 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, and for this functionality is preferably designed to interact with the first door closer. The triggering of the closing sequence control generated by the trigger unit, which in turn is initiated by the opening of the inactive leaf, is forwarded to a blocking unit via a transmission unit. Both the transmission unit and the blocking unit are further elements of the closing sequence control.

[0012] When triggered, the locking unit blocks the closing movement of the active leaf. Preferably, the locking unit only blocks the closing process from a predetermined or correspondingly set limit closing angle of the active leaf; in other words, the closing process for opening angles greater than the limit closing angle remains possible. Likewise, any opening process of the active leaf is preferably possible, regardless of any triggering by the trigger unit.

[0013] According to the invention, the locking system according to the invention provides that the locking unit is arranged on and / or in the second door closer. In other words, the locking unit interacts directly with the closer unit to effect the desired locking of the closing movement of the active leaf. This prevents the locking unit from acting directly on the active leaf itself without utilizing the functionalities already provided by the closer unit, which often has a significant dependence on the opening angle of the active leaf in terms of its effectiveness or the amount of force required.

[0014] Since the closer unit of the second door closer is located on the door leaf of the active leaf, it must be ensured that the triggering of the closing sequence control by the triggering unit, which interacts with the first door closer, reaches the closer unit of the second door closer. The transmission unit of the closing sequence control of the closer system according to the invention is specially designed for this purpose. The transmission unit comprises a rail section and a closer section coupled to it. "Coupled" within the meaning of the invention includes, in particular, mechanical operative connections.

[0015] The rail section is at least partially arranged in the slide rail and interacts with the triggering unit. In this way, a triggered closing sequence control can be transmitted along the slide rail, preferably into the area of ​​the second door closer. Here, the closer section takes over the transmission of the triggering. At least a portion of the closer section extends along the closer lever.

[0016] The closer section can also have further subsections that are arranged before or after the subsection arranged along the closer lever in the chain of effects. The decisive factor is that the closer section extends at least from the sliding block end to the closer end of the closer lever and in this way ensures that the triggering within the closing sequence control is transmitted from the slide rail to the closer unit of the second door closer arranged on the active leaf. For the purposes of the invention, the terms sliding block end and closer end are understood as areas that, in addition to the respective actual physical end of the closer lever, also include its immediate surroundings, in particular at least up to and including a correspondingly present bearing axis or bearing shaft.

[0017] The locking unit of the closing sequence control is arranged adjacent to the closer section, with the closer section interacting with the locking unit. In this way, a triggering of the closing sequence control, generated by the triggering unit, can be forwarded to the locking unit via the complete transmission unit comprising the rail section and the closer section, thus activating a locking of the active leaf's closing process.

[0018] Overall, the transmission unit, which is formed as a combination of rail section and closer section, establishes a secure and purely mechanical operative connection between the trigger unit, i.e. the first door closer on the passive leaf, and the locking unit on and / or in the closer unit of the second door closer on the active leaf.

[0019] In summary, the design of the transmission unit for the closing sequence control of the closer system according to the invention ensures, in particular, that the closing sequence control is transmitted between the slide rail, i.e., the rail section, and the locking unit arranged on and / or in the closer unit. Due to the extension of the closer section at least between the sliding block end and the closer end of the closer lever, this is ensured, in particular, independently of the opening angle of the active leaf and the resulting relative orientation of the closer lever both with respect to the slide rail and with respect to the closer unit. The influence of the position of the active leaf on the closing sequence control of the closer system can thus be minimized, and preferably even completely eliminated.

[0020] According to a first embodiment of the closer system according to the invention, it can be provided that the closer unit of the second door closer has a hydraulic system for driving and / or controlling and / or regulating a closing process of the active leaf, and the locking unit comprises a check valve in the hydraulic system for locking the second door closer, wherein the closer section has a check element for actuating the check valve. Hydraulic systems are often used in closer units, for example, to limit the closing speed of a closing movement of the corresponding door. When the door moves, hydraulic fluid in the closer unit is displaced from one volume to another, and the flow of hydraulic fluid is regulated by one or more valves.A check valve that completely blocks this flow can block the corresponding movement, in particular a closing process, because the flow of hydraulic fluid is prevented. The check valve can be arranged in the hydraulic system in such a way that this blocking only occurs when the door opens to a certain angle. The check valve can also be designed, for example, as a check valve in order to allow the hydraulic fluid to continue flowing in the opposite direction to an opening movement of the door. In particular, the use of a check valve can ensure that large blocking forces, which are provided by the check valve, can be generated even with relatively small actuation forces generated by the blocking element.In addition to simple operation, this can reduce the demands on the material of these components and also reduce wear during operation. The functional reliability of the entire closer system can also be increased. When the closing sequence control is triggered, the locking element is the last element in the transmission unit and actuates the check valve. The closing process of the active leaf can be blocked in this way. In one embodiment, the locking element can be designed as a locking lever. The locking lever can be used to actuate the check valve in a particularly simple and safe way. In an alternative embodiment, the locking element can be designed as a driver. The check valve can also be easily actuated using the driver.

[0021] According to a further embodiment of the closer system according to the invention, it can further be provided that the locking lever is designed as a two-armed, L-shaped lever with two legs, wherein the locking lever is mounted in the region of a connection point between the two legs on and / or in the closer unit of the second door closer, preferably on an end housing cover of the closer unit of the second door closer. The locking lever can preferably be mounted on a housing of the closer unit. The check valve is arranged inside the closer unit as part of the hydraulic system of the closer unit. By means of an L-shaped locking lever, the triggering, which has been transmitted to the closer shaft by the part of the closer section arranged along the closer lever, can be forwarded particularly easily to various points on the closer unit.Furthermore, by appropriately coordinating the length of the two arms of the L-shaped locking lever, the force exerted by the locking lever on the locking valve can be increased. In particular, an end face of the closer unit, which is usually covered by a housing cover, is a particularly preferred location for accessing a locking valve inside the closer unit, since the locking valve is often also located in this housing cover. If the locking valve is arranged inside the closer unit, the locking lever can control the locking valve through the housing cover. By mounting the L-shaped locking lever at the junction of its two arms, the direction of movement of the lever can be changed, preferably by 90°, and, as already explained above, a force-increasing lever effect can be achieved. This makes it even easier to initiate the triggering process inside the closer unit.

[0022] According to a further embodiment of the closer system according to the invention, it can further be provided that the check valve is arranged in the housing cover of the closer unit of the second door closer. In this way, the check valve can be controlled particularly directly and preferably without further transmission mechanisms by the locking element, in particular the locking lever or the driver. Overall, this enables an arrangement of the check valve and its control with a particularly small installation space requirement. Such a check valve around the housing cover can also enable the retrofitting of a closer unit as part of a closer system according to the invention. This may require that the corresponding hydraulic system of the closer unit is already designed for this retrofitting or can at least be prepared for it.

[0023] According to a further embodiment of the closer system according to the invention, it can further be provided that the closer section comprises a transfer element and a sleeve element coupled to the transfer element, wherein the transfer element extends between the sliding block end and the closer end of the closer lever, and wherein the sleeve element is displaceably mounted at the closer end parallel to a closer shaft of the second door closer, wherein furthermore the sleeve element is preferably coupled to the locking element. The transfer element is used to transmit the triggering along the closer lever. However, the closer lever is usually not arranged directly on a housing or body of the closer unit, but at a distance from a closer shaft that protrudes from the housing of the closer unit. This distance can be bridged by the sleeve element.If a locking element is present, it can preferably be coupled directly to the sleeve element. If the locking element is designed as a locking lever, a deflection of the sleeve element leads to a tilting of the locking lever and thus to the activation of the check valve. If the locking element is designed as a driver, the driver can be connected to the sleeve element, in particular clipped onto the sleeve element. By deflecting the sleeve element, the driver is then driven along and actuates the check valve.

[0024] According to a further embodiment of the locking system according to the invention, it can further be provided that the transfer element is designed as a two-armed transfer lever, wherein the transfer lever is pivotally mounted in and / or on a lever receptacle of the locking lever between an inactive position and an active position, wherein the transfer lever can be brought into its active position to forward a triggering by the triggering unit and in the process displaces the sleeve element. In this embodiment, the transfer element is designed as a single, preferably one-piece, two-armed transfer lever. Due to the two arms, a deflection of the transfer lever at the sliding block end can be particularly easily converted into a deflection of the opposite end of the transfer lever at the locking end. In its inactive position, no deflection of the transfer lever occurs.In its active position, however, the transfer lever is deflected, and this pivoting movement then displaces the sleeve element. The closing lever not only serves as an element for aligning or positioning the transfer element, but also provides the necessary space for this positioning through the lever mount. This enables a particularly space-saving arrangement of the transfer element or transfer lever.

[0025] According to a further embodiment of the closer system according to the invention, it can further be provided that the lever receptacle extends from the sliding block end to the closing end of the closer lever, wherein the lever receptacle is formed in the closer lever such that the transfer lever, in its inactive position, is arranged within the closer lever, and in its active position, protrudes from its pivot axis in the direction of the sliding block end via an underside of the closer lever facing away from the slide rail, and from its pivot axis in the direction of the closing end via an upper side of the closer lever opposite the underside. In this way, it is possible for the transfer lever to be arranged inside the closer lever and thus does not change the general appearance of the closer lever in its inactive position.The lever mount is designed in such a way that it has an opening on the underside towards the sliding block end and on the top towards the closer end, with a continuous opening formed in the closer lever between them. The pivot axis of the transfer lever is located in the central, continuous section of the lever mount. The term "central section of the lever mount" refers only to the arrangement of this section between the two sections with the openings facing the top and bottom, respectively. By appropriately selecting the arrangement of the central section of the lever mount along the closer lever, and thus the arrangement of the pivot axis of the transfer lever, the overall power transmission through the transfer lever can be influenced, in particular by selecting the transmission ratio.

[0026] According to a further embodiment of the locking system according to the invention, the transfer lever, in its inactive position, can be provided to be flush with the top or bottom of the locking lever. In its active position, the transfer lever is pivoted downward at the sliding block end, i.e., to the side facing away from the slide rail, and, as a two-armed lever, upward from its pivot axis to the locking end. This also displaces the sleeve element upward, thus transferring the release.

[0027] According to a further embodiment of the closer system according to the invention, it can further be provided that the rail section comprises a forwarding device for forwarding a triggering action by the triggering unit in a direction parallel to the slide rail and furthermore an activation device coupled to the forwarding device for forwarding the triggering action in a direction transverse to the slide rail, wherein the activation device has a coupling element for coupling to the closer section. The forwarding device can, for example, have a push rod and / or a cable pull. The coupling element can extend at least partially along a sliding path of the sliding block in the slide rail. Preferably, the coupling element extends along the complete or at least substantially complete sliding path of the sliding block in the slide rail.Alternatively, the coupling element can also be arranged in only one section of the slide path. The rail section of the transmission unit essentially has two functions: firstly, transmitting the activation of the closing sequence control along the slide rail and secondly, forwarding the activation to the closer section. By dividing the rail section into the transmission device and the activation device, both functions can be provided by separate component groups that are thus specifically tailored to the respective task.

[0028] The forwarding device, which is preferably designed as a push rod, can, for example, be fully integrated into the slide rail. The activation device receives, for example, a displacement parallel to the slide rail from the forwarding device and converts this into a movement transverse to the slide rail to control the closer section, in particular the transfer lever. Since the sliding block of the second door closer moves along the slide rail, the activation device is equipped with a coupling element. This extends in the slide rail along the sliding path of the sliding block, preferably along the entire sliding path, whereby the aforementioned conversion of the movement for controlling the transfer lever can be ensured for any position of the sliding block in the slide rail.In this way, the triggering of the closing sequence control can be forwarded, particularly independently of the opening angle of the active leaf.

[0029] According to a further embodiment of the locking system according to the invention, it can further be provided that the activation device has an activation pin coupled to the coupling element, wherein the activation pin is slidably mounted in a continuous receptacle of the sliding block, and wherein the activation pin is coupled to the locking section. The sliding block usually already has a continuous receptacle, namely for a rotatable connection and mounting on a sliding block bolt, which in turn is connected to the locking lever. Thus, the activation pin can preferably be slidably mounted in this already existing continuous receptacle, particularly preferably even in the sliding block bolt. Preferably, and in particular ensured by the mounting in the sliding block bolt, the activation pin is arranged slidably along the rotational axis of the connection of the locking lever to the sliding block.The bearing in the sliding block, particularly in the sliding block bolt, ensures that the activation pin can interact with the closer section, particularly the transfer lever, regardless of the position of the sliding block in the slide rail and the rotational position of the closer lever relative to the sliding block. Since the coupling element also extends over the sliding block's sliding path, the activation pin can also be controlled at any sliding block position. This enables a particularly simple and reliable transmission of the triggering from the rail section to the closer section.

[0030] According to a further embodiment of the closer system according to the invention, the activation pin can be spring-loaded against its deflection during the transmission of the triggering action. In this way, an unintentional continuation of the triggering action after the triggering action has ended can be prevented. When the triggering action ends, the force that displaces the activation pin and, via this displacement, transmits the triggering action to the closer section also ends. Due to the spring load against this deflection of the activation pin, the activation pin is automatically pushed back, thus ending the transmission of the triggering action. An unintentional blocking of the closing movement of the active leaf if the closing sequence control is not triggered can thus be avoided.The spring for generating the spring load can preferably act directly on the activation pin, but also on another point in the kinematic chain, for example on the transfer lever, the sleeve element, or the locking element.

[0031] According to a further embodiment of the locking system according to the invention, it can further be provided that the activation pin has a head element for coupling to the coupling element, wherein the head element is convexly curved. The convex shape of the head element improves the coupling to the coupling element. In particular, the head element can be mushroom-head-shaped. The head element serves for coupling to the coupling element. The activation pin can further have a rod element. The rod element extends through the receptacle of the sliding block. The sliding block can have a sliding block bolt for coupling to the locking lever. The rod element can extend through the sliding block bolt. In particular, the sliding block bolt can have the receptacle. The rod element has a first end and a second end. The first end is connected to the head element.The second end serves for coupling to the locking section, in particular to the transfer lever. A diameter of the head element is preferably larger than a diameter of the rod element.

[0032] According to a further embodiment of the locking system according to the invention, it can further be provided that the coupling element is designed as a sliding element coupled to the forwarding device via a coupling lever, wherein the sliding element is arranged or mounted in such a way that when the triggering is forwarded by the forwarding device, the sliding element also moves at least in a direction transverse to the slide rail. The coupling element extends, preferably over the entire sliding path of the sliding block in the slide rail. In embodiments in which external conditions prevent the coupling element from extending over the entire sliding path, the extension of the coupling element is nevertheless such that the door opening area of ​​the active leaf, which is crucial for the secure closing of the passive leaf, is covered. Due to the special arrangement orBy mounting the sliding element, it is possible to transmit the triggering of the closing sequence control transversely to the slide rail and thus to the closer section, in particular to the transfer lever. To transmit the triggering, the sliding element can, for example, interact with the activation pin. In particular, the sliding element can move the activation pin in a direction transverse to the slide rail when transmitting the triggering. For this purpose, the sliding element can, for example, have a stop for the activation pin, in particular for the head element of the activation pin. The stop thus serves to couple it to the activation pin, in particular to the head element of the activation pin. For example, the side of the sliding element facing the activation pin, in particular an underside of the sliding element, can form the stop. Alternatively, the stop can also be arranged on a side of the sliding element facing away from the activation pin.

[0033] According to a further embodiment of the locking system according to the invention, it can further be provided that the sliding element is guided in one or more slotted guides, wherein in the case of several slotted guides these are preferably arranged at equal distances along the sliding element, in such a way that when the triggering is transmitted by the transmission device, the sliding element is also displaced at least in a direction transverse to the slide rail. In this embodiment, the activation device is thus designed as a groove-sliding activator. In this way, the number of parts of the activation device can be reduced. By means of a slotted guide, which is preferably aligned at an angle to a longitudinal extent of the slide rail, for example, the coupling element is displaced at least partially transversely to the slide rail, starting from the transmission device and transmitted by the coupling lever.Multiple guide rails prevent the coupling element from jamming. This allows the triggering of the closing sequence control to be transmitted transversely to the slide rail and thus to the closer section, especially to the transfer lever. In addition to the guide rails described above, kinematically equivalent mechanical elements for transmitting the triggering of the closing sequence control transversely to the slide rail are also possible, such as a pivoting mechanism or a coupling gear.

[0034] According to a further embodiment of the locking system according to the invention, it can further be provided that the sliding element is pivotally mounted via a pivoting mechanism such that when the triggering is transmitted by the transmission device, the sliding element also moves at least in a direction transverse to the slide rail. In this embodiment, the activation device is thus designed as a coupling-pivoting activator. In this way, the activation device can be provided as simply and cost-effectively as possible and with precise bearings and guidance. The pivoting mechanism can, for example, have two pivoting levers. The sliding element can be pivotally mounted via the two pivoting levers, in particular so that the sliding element is also moved in the direction transverse to the slide rail.

[0035] According to a further embodiment of the locking system according to the invention, it can further be provided that the activation device has a roller arrangement, wherein the roller arrangement is movable together with the sliding block along the slide rail, wherein the forwarding device has a cable pull, wherein the cable pull is coupled to the roller arrangement, wherein the roller arrangement has a first roller as the coupling element, wherein the first roller is arranged such that when the triggering is forwarded by the forwarding device, the first roller moves at least in a direction transverse to the slide rail. In this embodiment, the activation device is thus designed as a cable pull activator. In this way, the number of parts of the activation device can be reduced and the chain of action simplified.In particular, this variant is characterized by its simplicity, the low number of components required, and thus also by reduced costs. The roller arrangement can have a roller arrangement body. The roller arrangement body can be connected to the sliding block. For example, the roller arrangement body can be designed as a carriage that slides with the sliding block through the slide rail. The first roller can be mounted on the roller arrangement body so as to be movable in the direction transverse, in particular perpendicular, to the slide rail. The first roller can be coupled, in particular connected, to the activation pin. In particular, the first roller can be preloaded in the direction of the activation pin. The roller arrangement can have two second rollers. The second rollers are fixedly arranged on the roller arrangement body. In particular, the second rollers serve as deflection rollers for the cable pull. The first roller and the second rollers are mounted so as to be freely rotatable.The cable preferably runs around the rollers of the roller assembly. In particular, the first roller is arranged between the two second rollers, preferably along the slide rail.

[0036] According to a further embodiment of the locking system according to the invention, it can further be provided that the locking system has an electrically controllable locking device for locking the active leaf, wherein the locking device is coupled or at least couplable with at least one element of the transmission unit, preferably with the activation device, or the triggering unit, or with the sliding block, to hold a closing movement of the active leaf. A locking device provides the functionality that a door leaf, in this case the active leaf, is locked, in other words, locked and thus deliberately held open, optionally for a limited period of time or, at least theoretically, for an unlimited period of time.This can be advantageous, for example, for doors, particularly fire doors, which are intended to be barrier-free during normal operation and should or must be closed only in the event of danger, for which the locking units of the locking system according to the invention can be used. During normal operation, this locking function often represents a desired convenience feature. In a preferred embodiment, the locking device can be coupled to the sliding block to prevent a closing movement of the active leaf. In particular, the locking device can be arranged along the slide rail downstream of the coupling element of the activation device in the opening direction.

[0037] According to a further embodiment of the locking system according to the invention, it can further be provided that the sliding block has an extension element, wherein the extension element has a locking section, wherein the locking section can be coupled to the locking device, in particular wherein the extension element extends along the slide rail away from the receptacle. In principle, the activation pin makes it difficult or even prevents a sliding block without an extension element from dipping beneath the locking device for coupling. By means of the extension element, the coupling of the sliding block to the locking device is thus enabled or simplified. The extension element preferably extends in the opening direction of movement starting from the receptacle of the sliding block along the slide rail. The extension element thus serves as an extension for the sliding block in the opening direction of movement.The locking section is preferably arranged at an end of the extension element facing away from the receptacle. The locking device can have a locking element. To couple the locking device to the sliding block, the locking element can, for example, be engageable with the locking section. For this purpose, the locking section can be designed, for example, as a recess.

[0038] As already described in detail above, the closing sequence control of the closer system according to the invention allows the active leaf to be specifically locked and thus secured or held, thus preventing the active leaf from closing. However, this essentially also represents the functionality of a holding device. By coupling the holding device to the transmission unit or the triggering unit, the locking unit, which is at least indirectly coupled to these units, can also be used and controlled by the holding device. In other words, a separate unit for locking the active leaf and controlling it, provided solely for the holding device, can be dispensed with.Thus, a locking device within the meaning of the invention refers only to that group of components that is different from the components of the closing sequence control, in particular a pulse generator for triggering the locking of the active leaf. Such a pulse generator can be, for example, an electromagnet, in particular a solenoid. Unnecessary components and the associated space requirements and costs can be avoided.

[0039] According to a further embodiment of the door closer system according to the invention, it can further be provided that the first door closer and the second door closer have a common, continuous slide rail, wherein the rail section of the transmission unit is arranged in the common, continuous slide rail. In other words, in this embodiment, only a single, continuous slide rail is provided, in which the sliding blocks of both door closers are slidably guided. Separate slide rails with specially adapted lengths can thus be dispensed with. This also makes it possible to create a particularly visually appealing appearance of the door closer system according to the invention.

[0040] According to a further embodiment of the closer system according to the invention, it can further be provided that the second door closer has a free-wheel function. The free-wheel function enables the active leaf to be opened and closed with almost no resistance. For this to happen, the active leaf must be pushed open once with force, thus pre-tensioning the corresponding door closer until the free-wheel area is reached. Once the free-wheel function is activated, the door or the active leaf can then be freely passed through without the counterforce of the door closer. By means of a second door closer with free-wheel functionality, this can also be provided by the closer system according to the invention. In particular, when combined with the holding device described above, this offers the additional advantage that the active leaf can also be held open after it has been opened with almost no resistance.

[0041] Furthermore, the object is achieved by a double-leaf door with a moving leaf and a fixed leaf, comprising a closing system with a first door closer for the fixed leaf and a second door closer for the moving leaf. The double-leaf door according to the invention is characterized in that the closing system is designed according to the invention. All the advantages described above with regard to a closing system according to the invention can thus also be provided by a double-leaf door according to the invention that has the closing system according to the invention.

[0042] The invention is described below with reference to the figures. Elements with the same function and mode of operation are provided with the same reference numerals in the figures.

[0043] They show schematically: Fig. 1An embodiment of the double-leaf door according to the invention, Fig. 2An embodiment of a transmission unit without triggering the closing sequence control, Fig. 3The embodiment of the transmission unit of Fig. 2 when the closing sequence control is triggered, Fig. 4An activation pin in deactivated and activated position, Fig. 5The embodiment of the transmission unit of Fig. 3 together with the closing unit in sectional view, Fig. 6The closing unit of Fig. 5 in detailed view, Fig. 7A locking system according to the invention with a locking device, Fig. 8A further embodiment of a transmission unit, Fig. 9A rail section of the transmission unit of Fig. 8 , Fig. 10A closer section of the transmission unit of Fig. 8 , Fig. 11The arrangement of a sliding block on an electronic locking device, and Fig. 12Various embodiments of a coupling element of an activation device.

[0044] Fig. 1 shows a double-leaf door 200 according to the invention with a fixed leaf 210 and a moving 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 moving leaf 220 is also pushed open sufficiently.

[0045] The closer system 100 has, in particular, a first door closer 110 for the inactive leaf 210 and a second door closer 120 for the active leaf 220. As shown, the entire closer system 100 can be arranged on the door 200 in a hinge-to-hinge mounting.

[0046] In particular, the second door closer 120, preferably and as shown both door closers 110, 120, is or are equipped with a slide rail 132 in which a slide block 134 is slidably mounted. As shown, a single, continuous slide rail 132 can be provided for both door closers 110, 120. Configurations with two separate slide rails 132 for both door closers 110, 120 are also conceivable, for example, to utilize the freed-up installation space for additional elements, such as a smoke and / or fire detector. The slide block 134 is rotatably connected to a slide block end 142 of a closer lever 140, the closer end 144 of which is connected to the closer unit 130, which is arranged on the door leaf of the active leaf 220.

[0047] Furthermore, the closer system 100 according to the invention is equipped with a closing sequence control 10. This closing sequence control 10 ensures that, when the inactive 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 inactive leaf 210 is not hindered and can be completely completed. For this functionality, the closing sequence control 10 has a trigger unit 20 coupled to the first door closer 110, a transmission unit 30, and a locking unit 80.The locking unit 80 is provided for the actual locking of the second door closer 120, wherein the transmission unit 30 transmits a triggering of the closing sequence control 10 by the triggering unit 20, in particular triggered by an opening of the passive leaf 210 beyond a triggering angle, to the locking unit 80, in particular regardless of where the sliding block 134 is located along its sliding path 138 in the sliding rail 132.

[0048] Fig. 2 to 6 show a first embodiment of the locking system 100 according to the invention of a double-leaf door 200 according to the invention, wherein in particular the transmission unit 30 is shown in the area of ​​the second door closer 120. The Fig. 2 to 6 are therefore described together below, with the individual representations being discussed separately.

[0049] In the Fig. 2 , 3In particular, the rail section 40 and a part of the closer section 60 are shown, each in a partially transparent plan view (Figure A) and a sectional view at the level of the activation pin 54 (Figure B), wherein in Fig. 2 there is no triggering of the closing sequence control 10 and in Fig. 3 the closing sequence control 10 is triggered. Fig. 4 shows the activation pin 54, also without (Figure A) and with triggering of the closing sequence control 10 (Figure B). Fig. 5 shows the transmission unit 30 as in Fig. 3 when the closing sequence control 10 is triggered, wherein the closer unit 130 of the second door closer 120 is also shown in a sectional view. Fig. 6 shows the area of ​​the closer unit 130 required for the locking in a sectional view, once without (Figure A) and once with triggering of the closing sequence control 10 (Figure B).

[0050] When the closing sequence control 10 is triggered, the triggering is carried out by the triggering unit 20 through interaction with the first door closer 110 (cf. Fig. 1 ) and forwarded to the transmission unit 30. The transmission unit 30 has, in particular, a rail section 40, which is arranged along and preferably completely within the slide rail 132. For example, the rail section 40 can have a forwarding device 42 designed as a push rod 44, wherein the push rod 44 can also be subjected to tensile stress. The forwarding device 42 can alternatively or additionally also be designed, for example, as a Bowden cable. When the closing sequence control 10 is triggered, in the illustrated embodiment, the push rod is moved parallel to the slide rail 132, see Fig. 2 , 3 .

[0051] A sliding element 50 is coupled to the push rod 44 via a coupling lever 56. The sliding element 50 represents a possible embodiment of a coupling element 48 and forms part of an activation device 46. As illustrated, the sliding element 50 can be displaceably mounted, for example, by a plurality of slotted guides 52 evenly spaced along the extension of the sliding element 50. The slotted guides 52 are aligned at an angle to the longitudinal extension of the slide rail 132, so that the movement of the sliding element 50 occurs at least partially transversely to the slide rail 132 when the triggering of the closing sequence control 10 is transmitted.

[0052] This sliding movement of the sliding element 50 transversely to the slide rail 132 enables the activation of an activation pin 54, which is slidably mounted in a receptacle 136 of the sliding block 134. The activation pin 54 is in Fig. 4shown separately and enlarged. It is clearly visible that the activation pin 54 is extended when the sliding element 50 is moved transversely to the longitudinal extent of the slide rail 132, so that it can transmit the triggering of the closing sequence control 10 to the closer section 60 of the transmission unit 30 (cf. Fig. 3 , 5 ).

[0053] Furthermore, since the coupling element 48 or the sliding element 50 preferably extends along the entire sliding path 138 (cf. Fig. 1 ) of the sliding block 134 in the slide rail 132, this forwarding of the triggering of the closing sequence control 10 from the rail section 40 to the closer section 60 is possible independently of a position of the sliding block 134 in the slide rail 132, and thus also independently of an opening angle of the active leaf 220.

[0054] In the illustrated embodiment of the closer system 100 according to the invention, the closer section 60 of the closing sequence control 10 has a transfer element 62 designed as a two-armed transfer lever 64, which extends from the sliding block end 142 of the closer lever 140 to its closer end 144. The transfer lever 64 is pivotally mounted in a lever receptacle 150 of the closer lever 140 between an inactive position 68 and an active position 66. In its inactive position 68, the transfer lever 64 can preferably be arranged completely within the lever receptacle 150 and thus within the closer lever 140, see Fig. 2 . To assume its active position 66, the transfer lever 64 is deflected and pivoted by the activation pin 54 so that it protrudes from the lever receptacle 150, in the area of ​​the sliding block end 142 via a bottom side 148 and in the area of ​​the closing end 144 via a top side 146 of the closing lever 140, see Fig. 3 ,5 .

[0055] By pivoting the transfer lever 64 at the closer end 144 of the closer lever 140, a sleeve element 70 is raised as the next element of the closer section 60, which is slidably mounted on a closer shaft 122 of the closer unit 130 of the second door closer 120 (cf. Fig. 5 , 6). This in turn actuates an L-shaped locking lever 72 which, in the embodiment shown, is mounted, for example, in the closer unit 130 in the area of ​​a housing cover 124 of the closer unit 130. The locking lever 72 has two legs 74, and the mounting takes place at a connection point 76 of these legs 74. In this way, the forwarded triggering of the closing sequence control 10 can be redirected to a blocking valve 82 which is also arranged in the housing cover 124. This blocking valve 82 represents, on the one hand, the essential component of the blocking unit 80 of the closing sequence control 10. On the other hand, the blocking valve 82 is also integrated into a hydraulic system of the closer unit 130, so that when the blocking valve 82 is activated, a closing movement of the closer unit 130 of the second door closer 120, and thus of the active leaf 220, can be blocked.

[0056] In summary, in particular, the design of the transmission unit 30 of the closing sequence control 10 of the closer system 100 according to the invention or of the double-leaf door 200 according to the invention ensures transmission of a triggering of the closing sequence control 10 between the slide rail 132, i.e., the rail section 40, and the locking unit 80 arranged on and / or in the closer unit 130. Due to the extension of the closer section 60 at least between the sliding block end 142 and the closer end 144 of the closer lever 140, this is ensured, in particular, independently of an opening angle of the active leaf 220 and the resulting relative orientation of the closer lever 140 both with respect to the slide rail 132 and with respect to the closer unit 130.The influence of the position of the active leaf 220 on the closing sequence control 10 of the closer system 100 can thus be minimized, preferably even completely eliminated. Furthermore, only low activation forces are required to generate high locking forces. Furthermore, the components of the closer system 100 according to the invention, which are used to transmit and forward the triggering of the closing sequence control 10, are not or only insignificantly affected by the opening of the active leaf 220, so that the influence of the door opening of the active leaf 220 on the functionality of the closing sequence control 10 can be minimized.

[0057] Fig. 7shows a possible further development of the locking system 100 according to the invention, in which, in addition to the closing sequence control 10, a locking device 102 is also provided. In Figure A, the locking device 102 is deactivated, whereas in Figure B it is activated. According to the invention, it can be provided in particular that the locking device 102 is coupled or at least coupleable to at least one element of the transmission unit 30, preferably to the activation device 46. In the illustrated embodiment, this is the activation pin 54. Alternatively, other structural sections of the transmission unit 30 or also the triggering unit 20 are also conceivable as coupling points for the locking device 102, for example, even the triggering unit 20 (not shown) on the inactive leaf 210 (see Fig. 1By coupling the locking device 102 to the activation pin 54, or another component of the transmission unit 30 or the triggering unit 20, the locking unit 80 of the closing sequence control 10 can be used and controlled by the locking device 102. Separate locking devices for the locking device 102 are thus eliminated. Locking devices 102 make it possible, for example, to lock the active leaf 220 and thus keep it open in a targeted manner.

[0058] In particular, however, as clearly evident from the illustration, it is still possible to control the activation pin 54 when the closing sequence control 10 is triggered. Thus, if, for example, in the event of a fire, the holding device 102 were to release the open active leaf 220, the closing sequence control 10 would still be active if the inactive leaf 210 were to be opened at the same time, thus preventing the active leaf 220 from obstructing the closing process of the inactive leaf 210. The inactive leaf 220 can only close completely once the inactive leaf 210 is closed. This enables the use of the closer system 100 according to the invention, for example, for fire doors.

[0059] Fig. 8 to 11 show a second embodiment of the locking system 100 according to the invention of a double-leaf door 200 according to the invention, wherein in particular the transmission unit 30 is shown in the area of ​​the second door closer 120. The Fig. 8 to 11are therefore described together below, with the individual representations being discussed separately.

[0060] The closing system 100 of the second embodiment essentially corresponds to the closing system 100 of the first embodiment from the Figures 2 to 7 Identical elements are provided with the same reference numerals and will not be explained in detail below. The locking system 100 of the second embodiment differs from the locking system 100 of the first embodiment essentially in the design of the activation device 46, the locking device 102, and the sliding block 134.

[0061] In the locking system 100 of the second embodiment, the activation pin 54 has a head element 160. The head element 160 serves for coupling with the coupling element 48. The head element 160 is convexly curved. In particular, the head element 160 can be mushroom-shaped. The activation pin 54 can further have a rod element 162. The rod element 162 extends through the receptacle 136 of the sliding block 134. The rod element 162 has a first end and a second end. The first end is connected to the head element 160. The second end serves for coupling with the locking section 60, in particular with the transfer lever 64. A diameter of the head element 160 is preferably larger than a diameter of the rod element 162.

[0062] In the locking system 100 of the second exemplary embodiment, the sliding element 50 is pivotally mounted via a pivot mechanism 164 such that, when the triggering is transmitted by the transmission device 42, the sliding element 50 also moves at least in a direction transverse to the slide rail 132. The pivot mechanism 164 can, for example, have at least two pivot levers 166. The pivot levers 166 can be arranged at a distance from one another along the sliding element 50. In particular, one pivot lever 166 can be arranged at one end and the other pivot lever 166 at an opposite end of the sliding element 50. The sliding element 50 can be pivotally mounted via the two pivot levers 166, in particular such that the sliding element 50 is moved in the direction transverse to the slide rail 132.

[0063] In the locking system 100 of the second embodiment, the sliding element 50 has a stop 51. The stop 51 serves for coupling with the activation pin 54, in particular for coupling with the head element 160. The stop 51 is arranged on a side of the sliding element 50 facing away from the activation pin 54.

[0064] In the locking system 100 of the second embodiment, the forwarding device 42 has a push rod 44 and a cable 170. The cable 170 can be configured as a Bowden cable. The push rod 44 is arranged, in particular, between the cable 170 and the activation device 46. In particular, a first end of the push rod 44 can be coupled to the cable 170, and a second end of the push rod 44 can be coupled to the coupling lever 56. By means of the cable 170, the push rod 44 can be pulled in a direction away from the activation device 46. The forwarding device 42 can further have a spring element 172, by means of which the push rod 44 is pretensioned in the direction of the activation device 46.

[0065] In Figures A of the Figures 8 to 10The closer system 100 is shown in a state in which the closing sequence control is not triggered. This can be the case, for example, when the passive leaf 210 is closed. If the closing sequence control is not triggered, the cable pull 170 is pulled away from the activation device 46. This raises the coupling element 48 and the activation pin 54. The transfer lever 64 is thus arranged in the inactive position 68. Thus, the blocking valve 82 is not actuated, and the second door closer 120 releases the active leaf 220.

[0066] In Figures B of the Figures 8 to 10The closer system 100 is shown in a state in which the closing sequence control is triggered. This can be the case, for example, when the passive leaf 210 is open. When the closing sequence control is triggered, the cable pull 170 yields, and the push rod 44 is pushed toward the activation device 46 by the pretensioning force of the spring element 172. As a result, the coupling element 48 and the activation pin 54 are lowered. The transfer lever 64 is thus arranged in the active position 66. The blocking valve 82 is thus actuated, and the second door closer 120 blocks the active leaf 220 at least in the closing direction.

[0067] In the closing system 100 of the second embodiment, the locking device 102 is arranged downstream of the coupling element 48 in the opening movement direction along the slide rail 132. Preferably, the coupling element 48 and the locking device 102 are spaced apart from each other. In particular, the coupling element 48 can extend only partially along the slide rail 132. The arrangement of the coupling element 48 and the locking device 102 on the slide rail 132 is shown in Figure A of the Fig. 11 shown.

[0068] In the locking system 100 of the second embodiment, the sliding block 134 further comprises an extension element 180. The extension element 180 has a locking section 182. The locking section 182 can be coupled to the locking device 102. The extension element 180 extends along the slide rail 132 away from the receptacle 136. The extension element 180 preferably extends in the opening movement direction, starting from the receptacle 136 of the sliding block 134, along the slide rail 132. The extension element 180 thus serves as an extension for the sliding block 134 in the opening movement direction. The locking section 182 is preferably arranged at an end of the extension element 180 facing away from the receptacle 136. The locking device 102 can comprise a locking element.To couple the locking device 102 to the sliding block 134, the locking element can, for example, be brought into engagement with the locking section 182. The locking section 182 can, for example, be designed as a recess.

[0069] In Fig. 11 the locking system 100 is shown in the state in which the sliding block 134 is locked by means of the locking device 102. In particular, Figure B shows the Fig. 11 the arrangement of the sliding block 134 on the locking device 102 is shown enlarged.

[0070] When the active leaf 220 is wide open, in particular when the active leaf 220 is opened so far that the sliding block 134 is locked by the locking device 102, the sliding block 134 is moved away from the coupling element 48 along the sliding rail 132 in the opening direction. The activation pin 54 is then not coupled to the coupling element 48. When the sliding block 134 is then moved in the closing direction when the active leaf is closed, the sliding block 134 is moved along the sliding rail 132 in the direction of the coupling element 48, so that the activation pin 54 is again coupled to the coupling element 48. The convex, in particular mushroom-head-shaped, design of the head element 160 of the activation pin 54 enables this coupling in a simple manner.

[0071] Fig. 12 Figures A, B and C show three different embodiments of the coupling element 48 of the activation device 46.

[0072] In Figure A of the Fig. 12 The coupling element 48 is designed as a sliding element 50 and is guided, in particular displaceably mounted, via one or more guide rails 52 at least in a direction transverse to the slide rail 132. The sliding element 50 is coupled via the coupling lever 56 to the forwarding device 42, in particular to the push rod 44 or the cable pull 170 of the forwarding device 42. The forwarding device 42 can move the sliding element 50, in particular when forwarding the trigger, in a direction transverse to the slide rail 132. This design of the coupling element 48 essentially corresponds to the design of the coupling element 48 in the locking system 100 of the first embodiment from the Figures 2 to 7 .

[0073] In Figure B of the Fig. 12The coupling element 48 is designed as a sliding element 50 and is movable, in particular movably mounted, via a pivoting mechanism 164 at least in a direction transverse to the slide rail 132. The pivoting mechanism 164 has at least two pivoting levers 166 for this purpose. The sliding element 50 is coupled via the coupling lever 56 to the forwarding device 42, in particular to the push rod 44 or the cable pull 170 of the forwarding device 42. The forwarding device 42 can move the sliding element 50, in particular when forwarding the trigger, in a direction transverse to the slide rail 132. This design of the coupling element 48 essentially corresponds to the design of the coupling element 48 in the locking system 100 of the second embodiment from the Figures 8 to 11 .

[0074] In Figure C of the Fig. 12The activation device 46 has a roller arrangement 190, wherein the coupling element 48 is designed as a first roller 192 of the roller arrangement 190. The roller arrangement 190 is movable together with the sliding block 134 along the slide rail 132. The roller arrangement 190 can have a roller arrangement body 196. The roller arrangement body 196 can be connected to the sliding block 134. The roller arrangement 190 can have two second rollers 194. The second rollers 194 are fixedly arranged on the roller arrangement body 196. In particular, the first roller 192 is arranged between the two second rollers 194. The rollers 192, 194 of the roller arrangement 190 are preferably freely rotatably mounted. The forwarding device 42 has a cable pull 170, wherein the cable pull 170 is coupled to the roller arrangement 190. In particular, the cable pull 170 rotates around the rollers 192, 194 of the roller arrangement 190.

[0075] The first roller 192 is arranged such that, upon transmission of the triggering signal by the transmission device 42, the first roller 192 also moves at least in a direction transverse to the slide rail 134. The first roller 192 can be mounted on the roller assembly body 196 so as to be movable in the direction transverse to the slide rail 132. If no triggering signal occurs, the cable 170 is pulled, and the first roller 192 is raised. Upon triggering, the cable 170 releases, and the first roller 192 is lowered. The first roller 192 can be coupled, in particular connected, to the activation pin 54. In particular, the first roller 192 can be pretensioned in the direction of the activation pin 54.

[0076] The cable pull 170 has a first end (not shown) and a second end 198. The first end is coupled to the trigger unit 20. The second end 198 is arranged in a fixed position, in particular with respect to the slide rail 132. In particular, the second end can be fixedly connected to the slide rail 132.
