EP3550102B1 - Assembly for a building door with a sealing unit and a locking device - Google Patents

Description

The invention relates to an assembly for a building door according to the preamble of claim 1.

Such an assembly comprises a sealing unit to be arranged on a door leaf, which has a housing and a seal assembly movable between a first, retracted position and a second, extended position along an adjustment direction to the housing for at least partial sealing of the door leaf in a closed position with respect to a floor and / or a door frame. In addition, a locking device which can be adjusted between an unlocking position and a locking position and which is used to lock the door leaf in the closed position is to be arranged on the door leaf.

In conventional building doors, for example internal doors or external doors on a building, a door leaf is arranged, for example, pivotably on a door frame. In this case, there is usually a gap between the door leaf and a floor of the building, which is necessary to enable the door leaf to be moved easily, unhindered relative to the door frame.

A building door can, for example, also be a patio door and, in this regard, a pivoting door or a sliding door.

In the case of an outside door in particular, but possibly also an inside door, it may be desirable for the door leaf in its closed position to be at least largely sealed off from the door frame and the floor in order to prevent drafts and sound transmission via the building door. For this purpose, the sealing unit arranged on the door leaf is used, the sealing assembly of which is adjustable, particularly when the door leaf is closed, in such a way that the door leaf is sealed off from the door frame and / or the floor. If the sealing unit serves as a floor seal, for example, the sealing assembly can be lowered when the door leaf is closed in order to close a gap between the door leaf and the floor and thus suppress a draft and sound transmission through the gap.

A sealing unit of this type should be easy to assemble, but also enable effective sealing when the door leaf is closed. In addition, the seal assembly must be adjustable in such a way that the door leaf can be opened and closed unhindered without dragging the seal assembly on the floor or on the door frame.

With one of the DE 10 2014 106 702 A1 known door sealing system, a sealing profile is movable on a door via an adjusting mechanism. A door sensor system can detect a closed state of the door in order to move the sealing profile depending on the closed state.

With one of the DE 297 22 616 U1 known door arrangement, an automatically lowerable bottom seal is embedded in a door leaf.

the DE 20 2013 100 864 U1 describes a floor rail for window and door elements, which has a compensation element which can be adjusted in its height position relative to a support element for adaptation to the floor level.

With one of the EP 1 772 586 B1 known bottom seal, a sealant is mechanically mountable in a seal housing.

the DE 297 20 978 U1 discloses a device in which a locking device in the form of a door lock is connected to a locking rail on the bottom of a door via a coupling device in the form of a control cable. A door handle is coupled to the control cable via a slide, so that the slide is moved by adjusting the door handle, thereby adjusting the control cable.

The object of the present invention is to provide an assembly for a building door as well as a building door which allow a reliable adjustment of a sealing assembly of the sealing unit in a simple manner as a function of the closed position of the door leaf.

This object is achieved by an object with the features of claim 1.

Accordingly, the assembly has a coupling device for coupling the locking device to the sealing unit in such a way that when the locking device is moved from the unlocking position to the locking position, the sealing assembly is moved into the second, extended position and / or when the locking device is moved from the locking position is moved into the unlocking position in the first, retracted position.

As part of the assembly it is provided that the sealing unit and the locking device of a building door are coupled to one another. An adjustment movement of the locking device is thus transmitted to the sealing unit via the coupling device, which is preferably designed for mechanical power transmission, so that when the locking device is locked, the sealing unit is transferred into the second, extended position and / or when the locking device is unlocked, the sealing unit is transferred to the first, retracted position will. The adjustment of the sealing unit thus takes place as a function of an adjustment of the locking device, which enables the sealing unit to be designed without its own drive.

The present invention is based on the knowledge that the actuation of the sealing unit and the actuation of the locking device must in principle take place simultaneously. For example, when the building door is closed, the locking device should lock the door leaf with a door frame as soon as the closed position is reached. In the closed position, the sealing assembly of the sealing unit should also be moved into the second, extended position in order to seal the door leaf against a floor, for example, and thus at least largely close a gap between the door wing and the floor. The adjustment of the locking device and the movement of the sealing assembly into the second, extended position should therefore take place after the closed position has been reached, which enables the sealing assembly to be moved as a function of and controlled by the locking device.

Because the locking device is coupled to the sealing unit via the coupling device, adjustment forces can be exerted by the locking device on the sealing unit are transmitted, which makes it possible to dispense with a separate drive for the sealing unit.

The locking device has an electromotive drive device, one or more locking assemblies with adjustable locking elements and a transmission element that can be driven by the drive device for adjusting the locking elements of the locking assembly. The transmission element is designed as an adjustable linkage on the door leaf and is coupled to the sealing unit via the coupling device. The drive device serves to adjust the transmission element, wherein an adjusting force can also be transmitted to the sealing unit via the coupling device in order to move the seal assembly between the first, retracted position and the second, extended position.

The locking device can be designed, for example, as a so-called multi-point lock with several locking assemblies, each with an adjustable locking element. The locking assemblies can be adjusted synchronously via the electromotive drive device by adjusting the transmission element, whereby the sealing unit is also actuated via the coupling device coupled to the transmission element and the sealing assembly of the sealing unit is thus adjusted depending on the position of the locking device. Such a multi-point lock can be used, for example, in a building door in the form of a house door.

The locking device can, alternatively, but also, for example, be implemented by a so-called turn-tilt fitting, by means of which a door or a window, for example a patio door, can be positioned between a locked position and a pivot position (in which a sash is pivoted about a vertical Swivel axis is possible) and a tilt position (in which a tilting of the sash about a horizontal tilt axis is possible) can be brought.

The coupling device can be designed as a Bowden cable, for example. In this case, a Bowden sheath is supported on the door leaf, for example, while a core of the Bowden cable guided in the Bowden sheath is connected on the one hand to the transmission element of the locking device and on the other hand to the sealing unit, so that adjusting forces from the transmission element of the Locking device can be transferred to the sealing unit.

Alternatively, the coupling device can also be designed as a so-called corner deflection, with a flexible force transmission element guided in a coupling guide. By means of such a corner deflection, forces can be deflected, for example, from a vertical direction of movement along which the transmission element in the form of the linkage of the locking device is to be moved, for example along the closing edge of the door leaf, into a horizontal direction of movement along the lower edge of the door leaf. The force transmission element can for example be designed as a flexible strip, for example made of spring steel, which is adjustable along the coupling guide, the coupling guide extending along a curved path and thus forces are deflected via the force transmission element.

Again, alternatively, the coupling device is designed as a driver for coupling the locking device to the sealing unit. The driver is designed in such a way that, for example, when a transmission element in the form of a linkage of the locking device moves, an adjusting force is introduced into the sealing unit for adjusting the sealing assembly and, in this respect, an adjusting mechanism of the sealing unit is carried along.

In one embodiment, an adjustment mechanism of the sealing unit is completely integrated into the housing of the sealing unit. The coupling device, for example in the form of a Bowden cable or a corner deflection, extends, for example, at one location into the housing of the sealing unit and is coupled within the housing to the adjusting mechanism of the sealing unit.

In one embodiment, the sealing unit has one or more spring elements for pretensioning the sealing assembly with respect to the housing in the direction of the first, retracted position or the second, extended position. The movement of the seal assembly in the direction of the first, retracted position or the second, extended position is thus spring-mechanically supported via one or more spring elements, so that the seal assembly, for example, in one direction via a tensile force transmitted via the coupling device in the form of the Bowden cable (against the Effect of the spring elements) and can be adjusted in the other direction by spring forces of the spring elements.

One or more spring elements can also be used to provide elasticity on the seal assembly, which makes it possible, for example, to compensate for unevenness in the floor or tolerances in the adjustment system, so that the seal assembly can reliably rest against the floor, for example when the door leaf is closed. A complex readjustment of the sealing assembly and the adjustment system of the sealing unit is no longer necessary.

In one embodiment, the coupling device can also be coupled to an adjustment mechanism for adjusting the seal assembly between the retracted position and the extended position via a spring element, for example in the form of a helical spring designed as a tension spring. For example, the coupling device can be coupled via a first spring element (for example in the form of a helical spring designed as a tension spring) to a first end of a connecting element which is connected to an adjusting mechanism for adjusting the sealing assembly (for example in the form of a lever mechanism). In contrast, a second end of the connecting element can be spring-preloaded with respect to the housing via a second spring element (for example in the form of a helical spring designed as a tension spring).

A spring element can thus, in one embodiment, be arranged in the power transmission train between the coupling device and the adjustment mechanism of the sealing unit, so that forces can be introduced into the adjustment mechanism via the spring element.

In one embodiment, the spring element can be designed, for example, as a helical spring that is to be tensioned.

In one embodiment, the spring element is designed, for example, as a leg spring with a first spring end in the form of a first leg and a second spring end in the form of a second leg. The first spring end can be fixed in place on the housing, for example, via a fastening element, while the second spring end is connected to a thrust element that can be adjusted relative to the housing (in particular transversely to the adjustment direction). To adjust the sealing assembly between the first, retracted position and the second, extended position, the thrust element is moved, for example via the coupling device and adjusting forces introduced via it or via spring forces of the spring elements.

The coupling device can act on the thrust element, for example, in order to introduce adjustment forces from the locking device into the sealing unit and to adjust the sealing assembly in the direction of the first, retracted position or in the direction of the second, extended position.

If the spring element is designed, for example, as a leg spring, the first spring end and the second spring end are preferably angled to one another and can be adjusted at an angle to one another. The spring element (along the adjustment direction of the seal assembly) is supported on the housing via the spring ends, while in one embodiment a sliding element is arranged centrally between the spring ends, for example at the location of a spring winding, via which the spring element is guided on the seal assembly transversely to the adjustment direction is, so that when the seal assembly moves, a transverse movement of the thrust element can be compensated for. For this purpose, the sealing assembly can have a suitable sliding guide, on which the slider connected to the spring element is slidably guided.

In one embodiment, it is conceivable that an adjustment movement of the locking device leads to a movement of the seal assembly both from the first, retracted position into the second, extended position and, conversely, from the second, extended position into the first, retracted position. If the locking device is moved into its locking position, in this case the sealing assembly is extended out of the housing of the sealing unit, for example in order to seal a gap between the door leaf and a floor. Conversely, if the locking device is transferred from the locking position to the unlocking position, the seal assembly is raised and moved into the first, retracted position, in which the seal assembly is at least partially drawn into the housing of the sealing unit. A movement of the transmission element of the In this case, the locking device is (directly) converted into a movement of the sealing assembly of the sealing unit.

In another embodiment, an adjustment movement of the locking device is converted into a movement of the seal assembly only in one direction, for example to transfer the seal assembly from the second, extended position to the first, retracted position when the locking device is unlocked. In the other direction, however, the movement of the seal assembly takes place independently of the locking device, controlled, for example, as a function of the door movement.

To prevent the seal assembly from dragging due to the seal assembly extending too suddenly into the second, extended position, the thrust element can be connected to the housing via a damping element, for example in the form of a gas pressure spring or the like. A movement of the thrust element is thus damped via the damping element, so that the movement of the seal assembly also takes place in a damped manner and an adjustment of the seal assembly, in particular in the direction of the second, extended position, is thus delayed in time.

For example, the sealing unit can have a locking assembly with a locking element and a triggering element. In the first, retracted position, the sealing assembly is blocked in this case, for example via the blocking element, relative to the housing and is thus held in position relative to the housing. If the release element is actuated when the door leaf is closed, the locking element is unlocked, so that the sealing assembly is moved from the first, retracted position to the second, extended position, driven, for example, by the spring forces of the (pretensioned) spring elements.

In this case, the sealing assembly is locked in the first, retracted position via the locking element, which is designed, for example, as a detent lever pivotably arranged on the housing, and is thus held in the first, retracted position via the locking element. If the door is closed, the release element triggers the locking element and, in particular, releases the latching of the locking element with the sealing assembly so that the sealing assembly can automatically move from the first, retracted position in the direction of the second, extended position.

The locking element can interact, for example, with the pushing element, which is adjustable transversely to the adjustment direction, on the housing of the sealing unit, in order to lock the pushing element and, moreover, the sealing assembly in the first, retracted position. If the latching is released by actuating the release element, the thrust element and thus also the seal assembly are released so that the seal assembly can be transferred from the first, retracted position in the direction of the second, extended position.

The trigger element can for example be operatively connected to a pressure element which, when the door leaf is closed, runs against a door frame, for example, and thereby actuates the trigger element. If the door leaf is closed, the release element triggers when the closed position is reached and unlocks the sealing assembly so that it is automatically moved in the direction of the second, extended position.

In one embodiment, the assembly has an adjustment mechanism for adjusting the seal assembly, which can be configured, for example, as a pinion gear. In such a pinion gear, a toothed rack is arranged on the seal assembly, which rack meshes with a pinion rotatably mounted in relation to the housing. The pinion can be driven in order to move the rack in this way and to adjust the seal assembly along the adjustment direction.

The pinion can be driven here, for example, via a drive linkage which is in toothing engagement with the pinion via a toothing and can be moved along a direction of movement in order to set the pinion in a rotary movement in this way. By driving the pinion via the drive linkage, the toothed rack and, above it, the seal assembly can be moved along the adjustment direction.

The drive linkage can, for example, be coupled to the coupling device so that the sealing assembly can be moved both in the direction of the extended position and in the direction of the retracted position by means of the adjustment mechanism. When the locking device is locked, the seal assembly is automatically extended and, conversely, when the locking device is unlocked, the seal assembly is automatically retracted.

However, it is also conceivable and possible to provide a drive for the seal assembly via the drive linkage, which drive is independent of the coupling device and can in particular be actuated in a controlled manner via the locking assembly. For example, the drive linkage can be prestressed against the housing via a mechanical spring, for example a compression spring, or also a hydraulic or pneumatic spring in the form of a damping spring, so that after the locking element is unlocked, the sealing assembly is moved into the extended position due to the spring prestress. In this case, the seal assembly is reset via the coupling device, for example via a driver, via which the drive linkage is reset and the seal assembly is thus raised.

In particular in such a configuration in which the seal assembly is moved both into the extended position and into the retracted position by force transmission via the coupling device, the coupling device can be operatively connected to the seal assembly, for example via a link element. According to the principle of the inclined plane, a force introduced via the coupling device is deflected via the link element in such a way that the seal assembly is adjusted along the adjustment direction between the retracted position and the extended position.

The gate element, which is arranged in one embodiment on the side of the seal assembly, has a gate that extends obliquely to the direction of adjustment, in which an engagement element assigned to the coupling device engages, so that when the coupling device moves, the engagement element in the gate is adjusted and thereby the Link element is adjusted together with the seal assembly along the adjustment direction.

A kinematically reversed arrangement is also conceivable and possible, in which the link element is assigned to the coupling device and is in engagement with an engagement element assigned to the sealing assembly.

An adjusting mechanism for adjusting the seal assembly can, in one embodiment, also be implemented by a lever mechanism which, for example, has a lever element and an adjusting lever articulated to the lever element. The adjusting lever can, for example, be mounted in a stationary manner on the housing. The lever element is hinged at one end to the seal assembly and with the other end arranged, for example, on a slide element which can be displaced in order to pivot the lever element between a pivoted-in position associated with the retracted position of the seal assembly and a pivoted-out position associated with the extended position of the seal assembly.

To ensure a defined movement of the seal assembly to the housing, the seal assembly can for example be guided along the adjustment direction on the housing so that the seal assembly can be moved (exclusively) along the adjustment direction to the housing.

In one embodiment, the coupling device can be decoupled from the sealing unit as a function of the position of the sealing assembly, so that the locking device can be adjusted independently of the sealing unit. The coupling device is therefore not permanently connected to the sealing unit, but rather detachable from the sealing unit. This enables the locking device to be adjusted independently of the sealing unit, so that the locking device can be adjusted, for example, between different unlocked positions (for example, in the case of a turn-tilt fitting, between an unlocked pivoting position and an unlocked tilting position) while the sealing unit remains in position.

For example, in the extended position of the sealing assembly, the coupling device can be coupled to the sealing unit, for example a connecting element in the form of a linkage of the sealing unit. In this position of the sealing assembly, the locking device can be in a locked position, for example. If the locking device is actuated in the direction of an unlocked position, the sealing assembly is thereby adjusted from the extended position to the retracted position, with tensile forces being able to be introduced into an adjustment mechanism of the sealing unit, for example. Once the sealing assembly has reached its retracted position, the coupling device can decouple from the sealing unit, so that further adjustment of the locking device can take place independently of the sealing unit. In this case there is no longer any operative connection between the sealing assembly and the coupling device. If the locking device is adjusted again in the direction of the locked position, the coupling between the coupling device and the sealing unit is re-established so that the sealing assembly is adjusted from the retracted position to the extended position, for example below Effect of a spring pretensioned when retracting (e.g. a tension or compression spring).

A building door can, for example, have a door frame and a door leaf that is movable, in particular pivotable or displaceable relative to the door frame. An assembly of the type described above is used on the one hand to lock the door leaf to the door frame in the closed position and also to seal the door leaf against a floor and / or against the door frame.

Fig. 1 shows a schematic view of a building door 1 which has a door leaf 10 which can be pivoted about a pivot axis D to a door frame 11 and which can be moved between an open position and a closed position to the door leaf 10 in order to open the building door 1 in a known manner or close.

The in Fig. 1 The illustrated embodiment, a locking device 2 in the form of a multiple lock is arranged on the door leaf 10, which is used to lock the door leaf 10 in its closed position with the door frame 11. The locking device 2 has a first bolt assembly 21 in the form of a door lock with a latch 210 and several further bolt assemblies 22 with bolt elements 220, which together serve to attach the door leaf 10 to the door frame 11 at different locations offset from one another on the outer circumference of the door leaf 10 to lock. The locking devices 21, 22 can be operated together via a transmission element 23 in the form of a linkage, which can be adjusted electrically by a drive device 20 in the form of an electric motor, in order to lock and unlock the locking elements 220 and latch 210 together and synchronously To adjust the door leaf 10.

The locking device 2 can be moved by an electric motor via the drive device 20. A manual actuation independent of the drive device 20 via a door handle 100 is also conceivable and possible.

Locking devices 22 can not only be arranged on the closing edge of the door leaf 10 facing away from the pivot axis D, but also on the upper edge and on the counter-closing edge of the door leaf 10 facing the pivot axis D.

The building door 1 has a sealing unit 3 with a sealing assembly 30, adjustable along an adjustment direction A, in the form of a sealing strip, which serves to seal a gap between the door wing 10 and a floor 4 on the underside of the door wing 10 when the door wing 10 is in is in the closed position. As will be explained below, the sealing assembly 10 can be extended in the adjustment direction A with respect to the door leaf 10 in order to close the gap in the closed position. The sealing assembly 30 can be drawn into the door leaf 10 counter to the adjustment direction A, in order in this way to enable the door leaf 10 to move unhindered towards the door frame 11.

Figures 2A, 2B and 3A, 3B show an exemplary embodiment of a sealing unit 3 on the door leaf 10 in the retracted position of the sealing assembly 30 ( Figures 2A, 2B ) and in the extended position of seal assembly 30 ( Figures 3A, 3B ). The sealing unit 3 has a housing 323 and, in this exemplary embodiment, two spring elements 31 formed by leg springs, via which the sealing assembly 30 is in the form of a is resiliently adjustable along the lower edge of the door leaf 10 extending sealing element.

In the exemplary embodiment shown, the sealing unit 3 does not have its own (motorized) drive, but is adjusted via the locking device 2. For this purpose, the transmission element 23 in the form of the linkage of the locking device 2 is coupled to the sealing unit 3 via a coupling device 24 in the form of a Bowden cable, for example, by connecting a flexible force transmission element 241 of the coupling device 24, which is guided in a coupling guide 240, to thrust elements 311, each with one Spring end 315 of the spring elements 31 are coupled, engages and can be adjusted to move the thrust elements 311.

In the illustrated embodiment, the coupling guide 240 is at one end assigned to the sealing unit 3 via a support element 242 on the housing 323 of the sealing unit 3 and also at its other end via a Bowden tube support (not shown in detail) relative to the door leaf 10, which is arranged fixedly on the door leaf 10 supported. The force transmission element 241 of the coupling device 24 is fixed to the transmission element 23 in the form of a linkage via a coupling element 230, so that the force transmission element 241 of the coupling device 24 can be moved relative to the coupling guide 240 by adjusting the transmission element 23 and the thrust elements 311 can thereby be adjusted.

The spring elements 31 are each connected with a spring end 315 to an associated push element 311 and are fixed with another spring end 314 via a fastening element 310 each on the housing 323 of the sealing unit 3. By adjusting the thrust elements 311, the position of the spring ends 314, 315 can be changed in relation to one another in order to move the sealing assembly 30 between the retracted position ( Figures 2A, 2B ) and the extended position ( Figures 3A, 3B ) to move.

In particular, the in Figures 2A, 2B, 3A, 3B illustrated embodiment, by adjusting the transmission element 23 in the adjustment direction V, the thrust elements 311 are offset by a distance X, as can be seen from the transition from Figure 2B towards Figure 3B It can be seen, in order to pivot the spring ends 314, 315 (under tension of the spring elements 31) with respect to one another and thereby to move the sealing assembly 30 from the retracted position into the extended position convict. In the extended position, the sealing assembly 30 protrudes outward from the housing 323 of the sealing unit 3 and seals a gap between the door leaf 10 and a base 4 on the underside of the door leaf 10, as is the case in particular Figure 3A can be seen.

When the transmission element 23 is adjusted against the direction of movement V, the seal assembly 30 is returned from the extended position to the retracted position and thus lifted off the floor 4 in that the force transmission element 241 of the coupling device 24 moves against the adjustment direction V and thereby the seal assembly 30 due to the spring preload of the Spring elements 31 is placed back in the retracted position.

By coupling the locking device 2 to the sealing unit 3, the locking device 2 and the sealing unit 3 are adjusted in a synchronous manner. Thus, when the door leaf 10 has reached its closed position, the locking device 2 for locking the door leaf 10 to the door frame 11 is activated and for this purpose the transmission element 23 is adjusted in the direction of movement V, as shown in FIG Figure 3B can be seen. As a result, the sealing assembly 30 is extended synchronously and the door leaf 10 is thus sealed off from the base 4.

If the door leaf 10 is to be opened again, the locking device 2 is unlocked by adjusting the transmission element 23 against the direction of movement V, whereby the sealing assembly 30 is lifted from the base 4 and returned to the retracted position.

In the closed position, the sealing assembly 30 rests on the base 4 with the spring elements 31 being spring preloaded. This enables tolerance compensation and compensation for unevenness in the floor 4. In addition, readjustment of the sealing unit 3 is not necessary or at least considerably simplified.

The sealing assembly 30 can be moved directly by adjusting the transmission element 23 of the locking device 2, as previously based on the exemplary embodiment according to FIG Figures 2A, 2B and 3A, 3B explained. In this case, for example, as explained above, by adjusting the transmission element 23 in the direction of movement V, a tensile force is transmitted via the force transmission element 241 of the coupling device 24 and introduced into the thrust elements 311, which are thereby displaced by a distance X and which Lower the seal assembly 30 over the spring elements 31. When the locking device 2 is locked, the sealing assembly 30 is thus extended. Conversely, if the locking device 2 is unlocked, the force transmission element 241 is reset against the direction of movement V, so that the sealing assembly 30 is raised again due to the spring action of the spring elements 31.

With an in Figures 4A-4D 6A-6D, the lowering of the sealing assembly 30 into the extended position takes place independently of the locking device 2, while the lifting for moving the sealing assembly 30 into the retracted position is effected by the locking device 2.

In the embodiment according to Figures 4A-4D through 6A-6D the sealing assembly 30 is supported via (at least) one spring element 31 on a housing 323 of the sealing unit 3, one spring arm 314 with a fastening element 310 fixed in place on the housing 323 and the other spring arm 315 of the spring element 31 designed as a leg spring on a push element 311, which is slidably guided on the housing 3 transversely to the adjustment direction A of the seal assembly 30, is attached. The thrust element 311 is supported on the housing 323 via a damping element 33 and is thus displaceable relative to the housing 323 in a damped manner.

The sealing unit 3 of the embodiment according to Figures 4A-4D through 6A-6D has a locking assembly 32 which serves to hold the thrust element 311 and, above it, the sealing assembly 30 in the retracted position ( Figure 4A ) to latch relative to the housing 323 and thus to hold it in the retracted position. For this purpose, the locking assembly 32 has a locking element 327 in the form of a locking lever which can be pivoted about a pivot axis 328 and which, in the retracted position of the sealing assembly 30, engages with the associated thrust element 311 and thus holds it in position relative to the housing 323, as in this case the end Figure 4A can be seen.

The locking assembly 32 has a pressure element 320 with a shaft 321, which is spring-pretensioned via a spring element 322 in the form of a pressure spring to form a housing section 324 of the housing 323 and is connected to a trigger element 326. The pressure element 320 is in a normal position, held by the collar 325 firmly connected between the housing section 324 and a collar 325 that is firmly connected to the shaft 321 acting spring element 322, from the housing 323 on the closing edge of the door leaf 10 to the outside, as shown, for example Figure 5B can be seen, and serves to interact with the frame 11 when the door leaf 10 is closed (in particular a frame edge 110 which, when the door leaf 10 is closed, is opposite the closing edge of the door leaf 10).

When the door leaf 10 is closed, the pressure element 320 runs onto the frame edge 110, as is the case in the transition from FIG Figure 5D added Figure 6D can be seen, and is thereby pressed in an unlocking direction U against the spring force of the spring element 322 into the housing 323. As a result, the release element 326 is moved in the unlocking direction U and acts on the blocking element 327 in such a way that the blocking element 327 is pivoted about the pivot axis 328 and is disengaged from the pushing element 311, as shown in the sequence of Figure 4A towards Figure 4D can be seen.

If the thrust element 311 is unlocked ( Figure 4D ), the sealing assembly 30 moves automatically due to the spring force of the spring element 31 (preloaded in the retracted position) in the adjustment direction A downwards to the bottom 4 and is thus transferred to the extended position.

The lowering of the sealing assembly 30 takes place due to the damping element 33, for example designed as a gas pressure spring, in a damped manner. The lowering of the sealing assembly 30 therefore does not take place suddenly, but rather with a time delay, which prevents the sealing assembly 30 from dragging on the floor before the door leaf 10 has reached the fully closed position.

In the exemplary embodiment shown, the spring element 31 is coupled to the sealing assembly 30 centrally on the spring element 31 via a slider 312 and, for this purpose, is slidably guided on a sliding guide 313 of the sealing assembly 30. When the seal assembly 30 is lowered, the slider 312 moves transversely to the adjustment direction A on the slide guide 313 and thereby compensates for a transverse movement of the thrust element 311 when the seal assembly 30 is lowered.

In this embodiment, the sealing assembly 30 is lowered by the interaction of the locking assembly 32 with the door frame 11 and thus basically independent of the locking device 2. The lowering occurs when the door leaf 10 is closed, immediately upon reaching the closed position.

In the closed position of the door leaf 10, the locking device 2 is in the locking position and thus locks the door leaf 10 to the door frame 11 via the locking assemblies 22 and the door lock 21, as shown, for example, in FIG Figure 6A is shown. If the door leaf 10 is to be opened again, the locking device 2 is actuated by adjusting the transmission element 23 to unlock the bolt assemblies 22 and the door lock 21, with a coupling device 24 in the form of, for example, a Bowden cable, a movement of the transmission element 23 and a retraction of the pusher element 311 in a direction of movement B opposite to the release direction U (see Figure 6C ) causes. The seal assembly 30 is then pulled back into the retracted position, in which the locking element 327 again latches with the pushing element 311, as shown in FIG Figure 4A and 5A to 5D is shown.

The force transmission element 241 of the coupling device 24 engages for this purpose, as shown in FIG Figure 6C is shown on the thrust element 311. When the locking device 2 is unlocked, the seal assembly 30 is returned to the retracted position and thus raised by the interaction of the transmission element 23 via the coupling device 24 with the seal assembly 30.

After the door leaf 10 is opened, the transmission element 23 in the form of the linkage is driven back by the drive device 20 into such a position that the sealing assembly can be extended again when the door leaf 10 is closed again and the locking element 327 is triggered.

In the embodiment according to Figures 4A-4D through 6A-6D only one spring element 31 is shown. However, there can also be two (or more) spring elements 31, each connected to a fastening element 310 and a pushing element 311, it being basically sufficient to provide a (single) locking assembly 32 for locking one of the pushing elements 311.

An in Figures 7A-7C and 8A-8C The illustrated embodiment is essentially functionally identical to the embodiment according to Figures 4A-4D through 6A-6D . Again, a locking assembly 32 is provided which secures the seal assembly 30 in the retracted position ( Figures 7A to 7C ) locked and can be triggered by interaction of a pressure element 320 with the door frame 11 to a locking element 327 to a To pivot pivot axis 328 and thereby release a thrust element 311. Due to the spring action of (at least) one spring element 31, the sealing assembly 30 is lowered in a manner damped by a damping element 33.

In the embodiment according to Figures 7A-7C and 8A-8C the pressure element 320 is spring-preloaded with respect to the release element 326 via a spring element 322, and the release element 326 is also spring-loaded with respect to the housing 323 via a spring element 329. When it hits the frame edge 110 of the door frame 11, the pressure element 320 first acts elastically via the spring element 322 and then in a block via a shaft 321 on the release element 326 and moves it in the release direction U to release the locking element 327, as in the transition from Figure 7C towards Figure 8C can be seen.

This takes place against the spring action of the spring element 329. When the door leaf 10 is opened, both the pressure element 320 and the release element 326 are therefore returned to the starting position ( Figure 7A ) posed.

In the embodiment according to Figures 7A-7C and 8A-8C the force transmission element 241 of the coupling device 24 is fixed to a coupling element 243 and is connected to the thrust element 311 so that when there is a pulling action, the force transmission element 241 acts on the thrust element 311 to return the seal assembly 30 to the retracted position.

Otherwise, this exemplary embodiment is identical to the preceding one based on FIG Figures 4A-4D through 6A-6D described embodiment, so that reference should also be made to what has been stated above.

Because the sealing unit 3 is coupled to the locking device 2 via the coupling device 24, a separate (electromotive) drive on the sealing unit 3 can be dispensed with. The adjustment in at least one direction of movement takes place via the drive 20 of the locking device 2, so that the sealing unit 3 is actuated as a function of an actuation of the locking device 2.

With an in Figures 9A, 9B and 10A, 10B illustrated embodiment of a sealing unit 3, in contrast to the embodiment according to Figures 7A to 7C and 8A to 8C , an adjusting mechanism 35 for adjusting the seal assembly 30 is provided, which is designed as a pinion gear.

In the adjustment mechanism 35, racks 354 extending along the adjustment direction A are firmly connected to the seal assembly 30 and are in engagement with pinions 353 rotatably mounted on the housing 323 of the seal unit 3. The pinions 353 are operatively connected to a drive linkage 350 in that the pinions 353 are in engagement with toothed sections of the drive linkage 350 in such a way that when the drive linkage 352 moves along a direction of movement C transverse to the adjustment direction A, the pinion 353 rotates (synchronously) and above the Racks 354 for lowering or raising the seal assembly 30 are driven.

In the exemplary embodiment shown, two toothed racks 354 are arranged offset from one another on the sealing assembly 30 along the direction of movement C (directed tangentially along the lower edge of the door leaf 10) and are in engagement with two associated pinions 353. Forces are thus introduced into the seal assembly 30 at locations that are spaced apart from one another.

It is also conceivable to use more than two toothed racks 354 with associated pinions 353.

The drive linkage 352 is connected to a slide 350 which is spring-pretensioned with respect to the housing via a spring element 351. Via the slide 350, the drive rod 352 can be moved in the direction of movement C for lowering the seal assembly 30 (in the direction of the extended position) and against the direction of movement C for lifting the seal assembly 30 (in the direction of the retracted position).

The sealing unit 3 also has a locking assembly 32 that corresponds to the locking assembly 32 of the exemplary embodiment Figures 7A to 7C and 8A to 8C functionally corresponds.

When the door leaf 10 is open, the seal assembly 30 is in its retracted position according to FIG Figures 9A, 9B . In this retracted position, the slide 350 and, above it, the drive linkage 352 are held in position by a locking lever 327 of the locking assembly 32, as shown in FIG Figure 9B is shown so that the seal assembly 30 is locked in its retracted position.

When the door leaf 10 is closed, a pressure element 320 of the locking assembly 32 interacts with an edge of the door frame 11 and is thereby pressed in an unlocking direction U into the door leaf 10, whereby a release element 326 acts on the locking lever 321, which is pivotable about a pivot axis 328 to the housing 323 and brings it out of engagement with the slide 350 of the adjusting mechanism 35. When the door leaf 10 is closed, the locking assembly 32 is triggered and the sealing assembly 30 is released, so that the sealing assembly 30, due to the spring preload of the slide 350 with respect to the housing 323, is automatically adjusted into the extended position via the pinion 353 meshing with the racks 354, as soon as the door leaf 10 is closed.

The movement of the drive linkage 152 is damped here via a damping spring 33 in the form of a gas pressure spring or the like, so that the lowering does not take place suddenly, but in a (slightly) delayed manner.

If the transmission element 23 is adjusted in the form of the linkage on the closing edge of the door leaf 11 to unlock the door leaf 10 and for this purpose in a direction of movement V, as in FIG Figure 10B As illustrated, moved, the coupling device 24 acts on a coupling element 243 in the form of a driver, which interacts with the carriage 350 and moves it counter to the direction of movement C. This also moves the drive linkage 352, thereby driving the pinion 353 and thereby lifting the seal assembly 30 (in Figure 10B only one pinion 353 is shown, the other has been omitted for the sake of clarity).

Via the locking device 2, the slide 350, carried along by the coupling element 243, is moved into the position shown in FIG Figure 9B The position shown is withdrawn, which corresponds to the retracted position of the seal assembly 30 and in which the slide 350 is locked again via the locking element 327, so that the seal assembly 30 is locked in its retracted position and remains in its retracted position 30 when the door leaf 10 is opened.

After unlocking, the transmission element 23 is moved back a certain distance so that the coupling element 243 in the form of the driver is removed from the carriage 350 and when the door leaf 10 is closed again, the sealing assembly 30 can be lowered unhindered from the coupling element 243 by adjusting the carriage 350 . The coupling element 243 is here via a The spring element 244 is pretensioned with respect to the housing 323 of the sealing unit 3, so that the coupling element 243 is returned (in the direction of movement C) in a spring-assisted manner.

Because the lowering of the sealing assembly 30 takes place immediately when the door leaf 10 is closed and, in addition, when the door leaf 10 is unlocked, the sealing assembly 30 is raised again immediately and in a manner coupled to the locking device 2, the sealing assembly 30 does not rub against the floor 4. The sealing assembly 30 is only lowered in the direction of the base 4 when the door leaf 10 has reached its closed position, and is immediately raised again when the door leaf 10 is unlocked for opening.

The embodiment according to Figures 11A, 11B and 12A, 12B Functionally essentially coincides with the exemplary embodiment according to FIG Figures 9A, 9B and 10A, 10B .

Instead of a mechanical spring element 351, as in the exemplary embodiment according to FIG Figures 9A, 9B and 10A, 10B is in accordance with the exemplary embodiment Figures 11A, 11B and 12A, 12B a damping spring 33 is provided for biasing the slide 350 with respect to the housing. In addition, the drive linkage 352 is not designed to be continuous, but rather divided into two linkage sections, which are connected to one another via a connecting linkage 356 for joint movement.

Otherwise, the exemplary embodiment is identical to the exemplary embodiment described above, so that reference should be made to the preceding explanations.

Figures 13 and 14 show schematic views of an exemplary embodiment in which a force transmission for adjusting the seal assembly 30 takes place via a link element 36 that, in the exemplary embodiment shown, is assigned to the seal assembly 30 and is driven directly via the coupling device 24.

In the illustrated embodiment, the link element 36 is connected to the seal assembly 30 in an elastically resilient manner along the adjustment direction A via a spring support 361, so that the seal assembly 30 can be adjusted (slightly) along the adjustment direction A with respect to the link element 36. The gate element 36 has a gate 360 extending obliquely to the adjustment direction A, in which an engagement element 245 in the form of a pin engages, which is displaceable along a movement direction C on a housing 323 of the sealing unit 3 and above the door leaf 10 mounted coupling element 243 is arranged. The coupling element 243 is connected to the force transmission element 241 of the coupling device 24 so that the coupling element 243 is moved along the direction of movement C when the force transmission element 241 is moved.

In the illustrated embodiment, the seal assembly 30 is driven both in the adjustment direction A for lowering the seal assembly 30 in the direction of the extended position and against the adjustment direction A for retracting the seal assembly 30 into the retracted position via the coupling device 24. When adjusting the transmission element 23 of the locking device 2 (in Figures 13 and 14 not shown) the force transmission element 241 of the coupling device 24 is moved along the direction of movement C, the coupling element 243 is displaced over it and, due to the link coupling between the coupling element 243 and the link element 36, the sealing assembly 30 is moved between its different positions.

Thus, the sealing assembly 30 is lowered when the coupling element 243 against the direction of movement C from the position according to Fig. 13 in the position according to Fig. 14 is moved. If, driven by the coupling device 24, the coupling element 243 is reversed in the direction of movement C from the position according to FIG Fig. 14 in the position according to Fig. 13 transferred, the seal assembly 30 is retracted.

Due to the link element 36 there is thus a forced coupling between the coupling device 24 and the seal assembly 30, which provides a force deflection according to the principle of the inclined plane and thereby moves the seal assembly 30 along the adjustment direction A, i.e. lowers or retracts.

In the extended position, the seal assembly 30 preferably rests on the floor 4, whereby due to the spring support 361 between the link element 36 and the seal assembly 30, a position adjustment between the link element 36 and the seal assembly 30 is possible, thus unevenness in the floor 4 can be compensated and a Tension in the system is avoided.

It should be noted in relation to the exemplary embodiment in accordance with Figures 13 and 14 that just as arrangements are also conceivable in which the link element 36 on the side of the Coupling device 24 is arranged and is in engagement with an engagement element 245 on the side of the seal assembly 30. In this respect, the mechanics can also be reversed kinematically.

The coupling device 24 can be designed in the manner of a Bowden cable with a core guided in a Bowden tube. However, it is also conceivable and possible, as shown schematically in Figures 15 and 16 is shown to design the coupling device 24 in the manner of a so-called corner deflection, in which the force transmission element 241 is guided in the form of a flexible strip, for example made of spring steel, in a coupling guide 240, as shown for example in FIG Fig. 16 is shown. To transmit the force, the force transmission element 241 can be moved within the coupling guide 240, the force transmission element 241 being firmly connected on the one hand to the transmission element 23 of the locking device 2 and on the other hand to the coupling element 243 on the side of the sealing unit 3, so that the coupling element 243 together with the force transmission element 241 the transmission element 23 of the locking device 2 is moved.

Figures 17 through 24A-24C show a further exemplary embodiment of a sealing unit 3, which has a sealing assembly 30 and is arranged on a lower edge of a door leaf 10 for sealing against a floor.

In the embodiment according to Figures 17 through 24A-24C the sealing unit 3 is operatively connected to a locking device 2 in the form of a multi-point lock, analogous to that described above with reference to FIG Fig. 1 has been described. In particular, the locking device 2 in the form of the multi-point lock has bolt assemblies 22 which can be adjusted together via a transmission element 23 in the form of a linkage in order to effect a locking between the door leaf 10 and a frame 11 at several locations when the locking device 2 is in is in a locked position.

The relocation device 2 is operatively connected to the sealing unit 3 via a coupling device 24. In the illustrated embodiment, the coupling device 24 is designed as a Bowden cable and serves to introduce an adjusting force from the locking device 2 into the sealing unit 3 in order to effect an adjustment of the sealing assembly 30 of the sealing unit 3 between different positions.

It should be noted at this point that the coupling device 24 can also be formed, for example, by a corner deflection or by another coupling.

How out Figures 18 through 24A-24C As can be seen, the sealing unit 32 has link elements 36 which are firmly connected to the sealing assembly 30 of the sealing unit 3, which can be adjusted along an adjustment direction A, and a force deflection for adjusting the sealing assembly 30 between an extended position ( Fig. 18 ) and a retracted position ( Fig. 19 and 20th ) cause.

In the illustrated embodiment, the coupling device 24 in the form of the Bowden cable has a coupling guide in the form of a Bowden sheath 240, which is supported at the end assigned to the sealing unit 3 within a housing 323 on a support element 242, as shown in particular Fig. 22 and Figure 23A can be seen. Within the coupling guide in the form of the Bowden sheath 240, a force transmission element 241 in the form of a core of the Bowden cable is guided and connected on the side of the sealing unit 3 to a damping element 33, which in the illustrated embodiment is designed, for example, as a gas pressure spring or as an oil damper.

How out Figures 23A and 23B As can be seen, the damping element 33 is connected to two connecting elements 34A, 34B in the form of rods, which establish an operative connection between the damping element 33 and an engagement element 245 which can be adjusted to one of the link elements 36 in each case. Each engagement element 245 is firmly connected to an associated connecting element 34A, 34B in the form of the respective linkage and can be moved relative to the respective link element 36 by moving the connecting element 34A, 34B.

On a side facing away from the damping element 33, each linkage 34A, 34B is spring-preloaded with respect to the housing 323 via an associated spring element 37A, 37B, so that the connecting elements 34A, 34B can be adjusted in an adjustment direction V to raise the seal assembly 30 from an extended position ( Fig. 18 ) to a retracted position ( Fig. 19 , 20th ) takes place against the spring preload of the spring elements 37A, 37B.

In the extended position according to Fig. 18 the sealing assembly 30 is lowered and lies against a floor below the door leaf 10 in a sealing manner. By adjusting the force transmission element in the form of the linkage 23 of the locking device 2 in the adjustment direction V, a force is introduced into the connecting elements 34A, 34B, so that the connecting elements 34A, 34B in the form of the rods are adjusted in the adjustment direction V and thereby the engagement elements 245 are adjusted to the link elements 36 fixedly connected to the sealing assembly 30.

This is in Figures 24A to 24C shown. Each engagement element 245 is in the extended position of the seal assembly 30 in an upper position in a gate 360 of the respective gate element 36, as shown in FIG Figure 24A can be seen. If the associated linkage 34A, 34B is moved in the adjustment direction V (driven by the locking device 2), the engagement element 245 is adjusted in the link 360, the engagement element 245 being moved linearly along the adjustment direction V together with the associated connection element 34A, 34B . Due to the force-deflecting effect of the slotted link 360 extending obliquely to the adjustment direction V, the link element 36 is raised in a stroke direction H, with a further adjustment of the locking device 2, the engagement element 245 can perform an idle stroke in the link 360, as in the transition from Figure 24B towards Figure 24C (corresponding to the transition from Fig. 19 towards Fig. 20 ) can be seen.

Because the link elements 36 fixedly connected to the sealing assembly 30 are moved synchronously via the connecting elements 34A, 34B in the form of the rods, the sealing assembly 30 is raised in the stroke direction H and thus out of the extended position ( Fig. 18 ) to the retracted position ( Fig. 19 , 20th ) adjusted. This takes place when the locking device 2 is adjusted to lock the door leaf 10 to the door frame 11.

If the locking device 2 is unlocked again, the force transmission element 23 in the form of the linkage of the locking device 2 is moved against the adjustment direction V. The sealing unit 3 is automatically reset due to the spring forces of the pretensioned spring elements 37A, 37B, so that the sealing assembly 30 is extended again and comes into contact with a floor located under the door leaf 10 (corresponding to the extended position according to FIG Fig. 17 ).

With another, in Figures 25 to 29A , 29B The illustrated embodiment, the sealing unit 3 is coupled to a locking device 2 in the form of a turn-tilt fitting, for example a patio door or the like. By means of such a turn-tilt fitting, a building door can be in a pivoted position The locking device 2 can be pivoted about a vertical pivot axis and, in a tilted position of the locking device 2, can be tilted about a horizontal tilt axis so that the door leaf 10 can also be brought into a tilted position.

The in Figures 25 to 29A , 29B The illustrated embodiment, the locking device 2 is coupled to the sealing unit 3 via a rod 23 running around the periphery of the door leaf 10, as shown in the sectional view according to FIG Fig. 28 can be seen. The rod 23 carries locking pins, which can be brought into engagement or disengaged by adjusting the rod 23 with associated strikers on the side of the door frame in order to pivot the door leaf 10 about a vertical pivot axis in the pivot position of the locking device 2 and in the tilt position of the locking device 2 to enable the door leaf 10 to be tilted about the horizontal tilt axis.

The coupling of the linkage 23 of the locking device 2 with the sealing unit 3 takes place in the illustrated embodiment via a coupling device 24 in the form of a driver, which-like Fig. 28 can be seen - is firmly connected to the force transmission element in the form of the linkage 23 of the locking device 2 via a fastening element 246, so that the driver 24 can be moved together with the linkage 23.

In the illustrated embodiment, adjusting mechanisms in the form of lever gears 39 are adjusted via the coupling device 24 in the form of the driver in order to thereby move the sealing assembly 30 of the sealing unit 3 between an extended position ( Fig. 25 ) and a retracted position ( Figs. 26, 27 ) to move.

How out Fig. 25 in sync with Figures 29A, 29B As can be seen, the coupling device 24 in the form of the driver is coupled to a linkage 34 via a first spring element 38A. An operative connection with the two adjustment mechanisms in the form of the lever mechanism 39 is established via the rod 34, so that the lever mechanism 39 can be actuated by adjusting the rod 34 and the sealing assembly 30 can thereby be adjusted.

In the extended position ( Fig. 25 ) the spring elements 38A, 38B are largely relieved. The sealing assembly 30 is held in the extended position via the lever mechanism 39 and is pressed into contact with a floor below a lower frame edge 110 of the door frame 11.

How out Figures 29A and 29B As can be seen, each lever mechanism 39 has a lever element 390 which is connected in an articulated manner to the seal assembly 30 by a lever end 392. The lever element 390 is also connected in an articulated manner to an adjusting lever 391, which is connected to the housing 323 of the sealing unit 3 so as to be pivotable at a lever end 394, but in a stationary manner. The lever element 390 also has a coupling pin 393 at an end facing away from the lever element 390, via which the lever element 390 is coupled to a link engagement 340 of the connecting element 34 in the form of the linkage, so that a tensile force in the adjustment direction V on the connecting element 34 in the form of the Linkage leads to an adjustment of the lever element 390.

If the linkage 23 of the locking device 2 is adjusted in the adjustment direction V, a tensile force is exerted on the first spring element 38A via the coupling device 24 in the form of the driver, which creates an elastic tension on the spring element 38A and also the connecting element 34 in the form of the linkage takes along in the adjustment direction V. As a result, the lever elements 390 of the lever mechanism 39 are pivoted in via the engagement with the link engagements 340, as is the case in the transition from Fig. 25 towards Fig. 26 It can be seen, so that the sealing assembly 30 is raised in a stroke direction H as a result.

During the adjustment, the second spring element 38B is also tensioned, so that a pretensioning with respect to the housing 323 is brought about.

In the position according to Fig. 26 the seal assembly 30 is already retracted. If the locking device 2 is adjusted further, for example by the locking device 2 from its pivot position (in which the door leaf 10 can be pivoted about the vertical pivot axis) into a tilt position (in which the door leaf 10 can be tilted about the horizontal tilt axis) effect, such an adjustment of the locking device 2 can take place with the movement of the coupling device 24 in the form of the driver, without the sealing assembly 30 being moved further in the stroke direction H. Such a movement of the coupling device 24 brings about a further tensioning of the spring element 38 in tension, so that a further adjustment movement of the locking device 2 is compensated for due to the elasticity of the spring element 38A.

If the locking device 2 and thus also the coupling device 24 in the form of the driver are reversed, the sealing unit 3 is automatically reset so that the sealing assembly 30 automatically moves into the extended position due to the spring forces of the spring elements 38A, 38B ( Fig. 25 ) is lowered.

With an in Fig. 30 The illustrated embodiment of a building door 1 has a locking device 2 in the form of a multiple lock with bolt assemblies 21, 22, with an electromotive drive device 20 in the form of a spindle drive being arranged directly on a power transmission element 23 in the form of a linkage of the locking device 2. The drive device 20 is here integrated into a profile part of the door leaf 10, as shown in FIG Fig. 31 can be seen.

In the embodiment according to Fig. 30 the building door 1 has an adjustment drive 12 which is integrated horizontally in an upper section of the door leaf 10 and is used for the electric motor adjustment of the door leaf 10 between a closed position and an open position. Both the adjusting drive 12, which acts on a secondary closing edge of the door frame 11, and the drive device 20 of the locking device 2 are connected to a control device 13, which is used to control the operation of the adjusting drive 12 and the locking device 2.

The power transmission element 23 in the form of the linkage of the locking device 2 can be adjusted by an electric motor via the drive device 20 of the locking device 2, so that the bolt assemblies 21, 22 of the locking device 2 can thereby be moved synchronously. Due to a coupling via a coupling device 24, for example in the form of a Bowden cable or a corner deflection, an adjustment of a sealing assembly of a tightness 3 can also take place.

In the illustrated embodiment, the drive device 20 is designed as a spindle drive, which - as in Fig. 32 - has a spindle 201 which can be driven by an electric motor and a spindle nut 201 which is in thread engagement with the spindle 200. By rotating the spindle 200 by an electric motor, the spindle nut 201 can be moved longitudinally along the spindle 200 in order to move the linkage 23 coupled to the spindle nut 201 linearly on the door leaf 10.

In the illustrated embodiment, the spindle nut 201 is connected to a closing element 202, which serves as a closing aid. In the closing element 202 is a guide track 103 is formed, which can be curved (as in the illustrated embodiment) or alternatively as an inclined plane and cooperates with a pin element 111 on the side of the door frame 11 to provide support in the last phase of the closing movement of the door leaf 10 when closing the door leaf 10 Door leaf 10 to provide.

Thus, the pin element 111 on the door frame 11 - immediately before the door leaf 10 is completely closed - in engagement with the guide track 203 of the closing element 202.By moving the closing element 202 together with the linkage 23 of the locking device 2 linearly on the door leaf 10, the pin element 111 be brought into engagement with the closing element 202 and thereby the door leaf 10 are pulled towards the door frame 11, so that a final path for moving the door leaf 10 into the door frame 11 can be supported by the drive device 20 by an electric motor.

Figures 34A, 34B and 35A, 35B show a further exemplary embodiment of a sealing unit 3, which functionally largely corresponds to the exemplary embodiment Figures 25-29 corresponds, so that reference should also be made to what has been said above. In particular, in the illustrated embodiment, a seal assembly 30 is connected to a lever element 390 of a lever mechanism 39 and is moved between a retracted position ( Figure 34B ) and an extended position ( Figure 34A ) adjustable.

In the illustrated embodiment, a connecting element 34 in the form of a linkage via a spring element 38C in the form of a compression spring against a housing section firmly connected to the housing 323 of the seal 3 is pretensioned in that the spring element 38C is between the housing section 323B and a firmly connected to the connecting element 34 connected driver portion 344 is supported and is tensioned when adjusting the connecting element 34 in an adjustment direction V under pressure. If the connecting element 34 is thus used to adjust the seal assembly 30 from the extended position ( Figure 34A ) to the retracted position ( Figure 34B ), the spring element 38C is tensioned under pressure, so that the seal assembly 30 can be reset in the direction of the extended position supported by the pretensioning spring force of the spring element 38C (in this respect, in the exemplary embodiment, a spring element 38B at the other end of the connecting element 34 can be used as in according to the embodiment Figures 25-29 be waived).

Another spring 38D is provided between sections of the connecting element 34 and serves to compensate for elastic play.

The connecting element 34 is in accordance with the exemplary embodiment Figures 34A, 34B and 35A, 35B connected to a coupling piece 341 in the form of a latching element, which is used to produce a releasable coupling with the coupling device 24. The coupling piece 341 has a latching head 342 arranged on a leg 346 for latching with a latching opening 323A on the housing 323, which is elastically adjustable and is connected to an actuating section 343 in the form of a tension spring, so that an adjustment of the latching head 342 is effected by actuating the actuating section 343 can be. On a side facing away from the latching head 342, a form-fit element 345 is formed, which is used to establish the coupling with a coupling element 243 of the coupling device 24.

In the extended position of seal assembly 30 ( Figure 34A and 35A ) the coupling device 24 is coupled to the coupling piece 341 and above it to the connecting element 34 of the sealing unit 3. This is achieved in that the latching head 342 is in contact with a surface of the housing 323 and the leg 346 carrying the latching head 342 is elastically offset inwardly to another, opposite leg 347 of the coupling piece 341, so that a form fit between the coupling element 243 the coupling device 24 and the form-fit element 345 of the coupling piece 341 is made, as shown in FIG Figure 35A can be seen. When the coupling device 24 is adjusted in the adjustment direction V to retract the sealing unit 30, the coupling piece 341 is thus moved together with the coupling device 24 and the sealing assembly 30 is thus retracted.

If the location of the latching opening 323A on the housing 323 is reached when the coupling piece 341 is adjusted, the latching head 342 latches into the latching opening 323A of the housing 323, as is the case Figure 35B can be seen. This position of the sealing unit 3 corresponds to the retracted position of the seal assembly according to FIG Figure 34B (see the retracted lever gear 39). Due to the latching via the coupling piece 341, the sealing unit 3 is held in this position, with the fact that the leg 346 is removed from the opposite leg 347 and the form-locking element 345 is thus displaced outwards, the form-locking between the coupling device 24 and the coupling piece 341 being canceled and the coupling device 24 can be adjusted further in the adjustment direction V independently of the sealing unit 3. The one with the The locking device 2 connected to the coupling device 24 can thus be adjusted independently of the sealing unit 3, for example to reach an unlocked position or to move the locking device 2 between different unlocked positions (for example a pivoted position and a tilted position).

If the locking device 2 is set back and the coupling device 24 is thus brought closer to the coupling piece 341 again (opposite to the adjustment direction V), the coupling device 24 moves with the coupling element 143 into the receptacle formed between the legs 346, 347 and reaches the actuating section 343 The shape of the tension spring interacts, which has the effect that the latching head 342 is lifted out of the latching opening 323A of the housing 323 and the latching is thus canceled.

The seal assembly 30 is thus no longer held in the retracted position. The sealing assembly 30 can thus be extended again by moving the locking device 2 counter to the adjustment direction V and supported by the pretensioning spring action of the spring 38C which is tensioned under pressure in the retracted position.

The idea on which the invention is based is not restricted to the exemplary embodiments described above, but can in principle also be implemented in a different manner.

An assembly of the type described above can be used in very different building doors, for example interior doors or exterior doors.

An assembly of the type described can not only be used to seal a door leaf against the floor, but also, for example, to seal against the door frame.
