Description

The present invention relates to a door element of a mobile partition. Furthermore, the invention relates to a mobile partition with the door element.

Mobile partition walls include individual, movable wall elements that are suspended by means of rollers in a ceiling guide rail within a room to be divided. To erect the partition, the individual wall elements are released from a lock and moved along the ceiling guide rail. When the partition is removed, the wall panels are stored in a storage area. To close the partition, the wall elements are placed close together in the wall plane and clamped using sealing strips, which are extended against the ceiling and/or the floor. In addition to the wall elements, a mobile partition can also include a door element, which, comparable to a wall element, hangs on the ceiling guide rail. Such a door element includes an element frame that hangs on the ceiling guide rail and a door leaf arranged in the element frame.

It is the object of the present invention to provide a door element of a mobile partition that enables comfortable operation of the door element with the most sound-absorbing design possible.

The problem is solved by the features of the independent claims. The dependent claims relate to preferred embodiments of the invention.

The invention shows a door element for a mobile partition. In addition to this door element, the mobile partition can also include one or more wall elements. Furthermore, the mobile partition can have a ceiling guide rail on which the door element and, if necessary, the wall elements can be hung and moved.

The door element includes an element frame and a door wing (also called door leaf) attached to the element frame. The door leaf in turn includes a door leaf frame. The door leaf frame is used to attach other elements of the door leaf. For this purpose, the door leaf frame can be designed as a classic frame to which a cover plate is attached on both sides. However, at least one stable cover plate of the door leaf can also be used to accommodate the other components, so that this cover plate then forms the door leaf frame.

The door leaf is preferably rotatably mounted in the element frame, so that it is a revolving door. For this purpose, straps are used in particular to attach the door leaf to the element frame in a rotatable manner. Preferably, the element frame comprises at least one column area, which is located next to the door leaf and on which the door leaf is attached in a rotatable manner. A secondary closing edge is formed between this column area and the door leaf. A column area of the element frame can also be formed on the main closing edge of the door leaf. Alternatively, however, it is also possible for the door leaf on the main closing edge to interact with another door element or wall element of the mobile partition or for the main closing edge to be formed between the door leaf and an area fixed to the building, for example an adjacent building wall.

The element frame preferably also extends into an area above the door leaf, so that the entire door element can be higher than the door leaf.

It is preferably provided that the element frame is covered on both sides with one or more cover panels. However, at least one of the cover panels can be designed to be so stable that it is used as an element frame and can accommodate other components of the door element; so that, for example, the suspension (rollers) and/or the straps can be attached to the cover plate.

Side seals are preferably provided on both sides of the door element. Similar seals are located on the adjacent door elements or wall elements. These side seals are preferably designed to be alternately concave and convex and, when the mobile partition wall is constructed, they interlock with one another in the longitudinal direction in order to achieve sound insulation. Furthermore, it is preferably provided that so-called sealing strips can be extended from the door element, preferably also from the other door and wall elements of the partition, for soundproof insulation from the ceiling and floor after the respective element is in its assembly position.

Of particular interest in the present case is the sealing strip, which can be extended downwards on the door leaf, i.e. is arranged at the lower end of the door leaf. For this purpose, it is provided that a seal carrier is arranged on the door leaf frame so that it can be moved vertically. For this purpose, this seal carrier is guided in a linearly movable manner in the vertical direction, in particular on the door leaf frame. The sealing strip is arranged on the seal carrier. The sealing strip can be extended at the lower end of the door leaf.

If the seal carrier moves vertically downwards, the sealing strip at the lower end of the door leaf is extended. If the seal carrier moves vertically upwards in the opposite direction, the sealing strip at the lower end of the door leaf is retracted.

In a preferred variant, the seal carrier is only guided in a linearly movable manner on the door leaf frame. From a general perspective, the movement of the seal carrier can be composed of several different movement vectors. What is crucial here is that the seal carrier moves vertically downwards and vertically upwards with at least one of its movement vectors in order to move the sealing strip towards the floor and retract it again.

As will be described in detail, there is preferably a movement device between the sealing strip and the seal carrier, so that the sealing strip can also be moved relative to the seal carrier.

While the door element described here, as part of the mobile partition, is moved, the sealing strips are retracted as completely as possible into the door element. The space between the top edge of the door element and the ceiling guide rail or between the bottom edge of the door element and the floor is called “ceiling clearance” or “floor clearance”. In certain installation situations, ground clearances of, for example, 20 to 100 mm may be required, as fluctuating structural loads can lead to ceiling deflections that vary over time in one and the same building. Similar to the ceiling deflection, the deflection of the floor is also relevant, as this can change significantly depending on the load, for example the number of people in the room. So that the door leaf of the door element is soundproof when the door is closed to the floor, the sealing strip must extend from it when the door leaf is closed and press it against the floor. However, when opening the door leaf, the sealing strip should not be fully extended so that the door leaf can be opened unhindered and does not drag on the floor.

The seal carrier arranged in the door leaf frame allows the sealing strip to be set to a specific height, which means that The current ground clearance, possibly changed by ceiling or floor loads, can be taken into account. In order to fix this relative position between the door leaf frame and the seal carrier, the door element preferably comprises a switchable brake. The brake is designed to fix the seal carrier relative to the door leaf frame in a braking state and to release the seal carrier relative to the door leaf frame in a release state. If the switchable brake is in the release state, the seal carrier can be moved relative to the door frame in order to set a basic distance between the sealing strip and the floor. If the switchable brake is in the braking state, the seal carrier is fixed relative to the door frame, so that the basic distance between the floor and the sealing strip is fixed.

It is preferably provided that the brake comprises a brake switching element which projects into a gap of a closing edge, in particular a secondary closing edge. Of particular interest here is the side secondary closing edge, which is located between the door leaf and the element frame. Because the brake switching element protrudes into this secondary closing edge or into the main closing edge, the brake element can be switched when the door leaf is closed and opened.

In particular, the brake is designed to keep the brake in the release state when the brake switching element is pressed in.

The brake switching element can in particular be designed as a pin. In particular, the brake switching element is designed and arranged in such a way that it is pressed in when the door leaf is closed.

Furthermore, it is preferably provided that the brake has a braking surface, preferably formed by a brake pad, and preferably has a pressure spring. The pressure spring actuates the braking surface in particular. The pressure spring preferably presses the braking surface, in particular the brake lining, against the seal carrier, whereby the seal carrier is fixed relative to the door leaf frame. The brake switching element is preferably arranged so that in the pressed state it can release the braking surface, in particular the brake pad, from the seal carrier against the force of the pressure spring in order to release the brake.

The brake is particularly preferably attached to the door frame. The brake preferably comprises a brake housing. This brake housing is preferably arranged to be linearly movable on the door frame. In particular, the brake housing is linearly movable in the horizontal direction.

The pressure spring described is preferably attached at one end to the door leaf frame and at the other end to the movable brake housing. Furthermore, it is preferably provided that the described braking surface, in particular the brake lining, is preferably arranged on the brake housing. A brake lever, which is preferably to be used, connects the brake switching element to the brake housing. The brake lever is preferably accommodated so that it can rotate relative to the door frame. It is preferably provided that the brake lever is rotated by pressing in the brake switching element and thereby releases the braking surface from the seal carrier against the force of the pressure spring.

Furthermore, it is preferably provided that the door frame comprises at least one cross member. The brake is preferably arranged on this at least one cross member.

The seal carrier preferably has parallel vertical elements. These vertical elements extend in the vertical direction. For example, vertical elements are rods or pipes. The vertical elements are preferably passed through the cross member of the door frame.

In addition to the vertical elements, the seal carrier preferably comprises at least two parallel transverse elements that connect the vertical elements to one another. In particular, the at least one cross member of the door leaf frame is located between the transverse elements of the seal carrier.

It is preferably provided that the door leaf frame comprises at least one vertical support on which the seal carrier is guided in a linearly movable manner.

On the seal carrier, in particular on the transverse elements, there are preferably rolling bodies, in particular rollers, and/or sliding bodies, for linearly movable guidance of the seal carrier on the door leaf frame.

Furthermore, it is preferably provided that the door element comprises a vertically movable raising and lowering unit in the element frame. There is preferably a driver on the seal carrier. The driver projects into the preferably lateral gap of the closing edge, in particular the secondary closing edge between the door leaf and the element frame. The driver is arranged and designed in such a way that it can be carried along by the raising/lowering unit.

The driver can preferably be placed on the raising/lowering unit. This is particularly intended when the door leaf is closed.

In particular, the driver is designed in such a way that it can be carried along by the raising/lowering unit when the door leaf is closed and, if necessary, at very small opening angles, and is separated from the raising/lowering unit when the door leaf is open and can therefore no longer be carried along .

If the opening angle of the door leaf is correspondingly small, the driver preferably rests on the lifting-lowering unit and is thus taken upwards by the lifting-lowering unit; The brake is in particular in the released state.

If the lifting-lowering unit moves downwards, the driver can lift off the lifting-lowering unit if necessary, but is usually moved downwards by the weight acting on the seal carrier and an optional extension spring and therefore lies on the lifting Lowering unit.

The driver preferably has an inclined plane in order to interact with the raising/lowering unit; Additionally or alternatively, the raising/lowering unit preferably has an inclined plane in order to interact with the driver. In particular, the at least one inclined plane is arranged and designed to lift the driver onto the raising-lowering unit if the driver is arranged too far down relative to the lifting-lowering unit when the door leaf is closed.

The raising and lowering unit in the element frame can, for example, be operated electrically, hydraulically or mechanically. In many applications, for example, there is a connection for a crank on each element (door element or wall element). The sealing strips can be moved up and down using such a crank. It is therefore preferably provided that the raising/lowering unit described here is designed not only to move the driver, but also to do so is designed to extend a sealing strip at the bottom and/or a sealing strip at the top end of the element frame. At the lower end of the element frame, the sealing strip arranged next to the door leaf can be very narrow and is therefore also referred to as a sealing foot.

The door leaf preferably has a slot on the closing edge, in particular the secondary closing edge, through which the driver extends and can therefore protrude into the gap and can move in the vertical direction in the slot. Preferably, the driver is designed so long that when the door leaf is closed, it not only protrudes into the gap in the closing edge, but also into the adjacent area of the element frame.

Preferably, the door element preferably comprises an extension spring which urges the seal carrier to move downwards relative to the door leaf frame. Using the raising/lowering unit, the seal carrier can be raised against the force of the extension spring. Particularly preferably, the extension spring is tensioned between one of the transverse elements of the seal carrier and the at least one cross member of the door leaf frame.

As described at the beginning, the sealing strip is preferably not firmly arranged on the seal carrier. Preferably, a movement device is used which is designed to move the sealing strip in and out vertically relative to the seal carrier.

The seal carrier is preferably arranged and/or designed to move the sealing strip by a greater distance than is possible with the movement device.

The seal carrier is preferably designed to move the sealing strip by a greater distance than the movement device displaces the sealing strip.

The movement device preferably comprises a movement device switching element which projects into the gap of the preferably lateral closing edge, in particular the secondary closing edge between the door leaf and the element frame, in order to switch the movement device when the door leaf is closed and opened.

Particularly preferably, the movement device is designed to extend the sealing strip relative to the seal carrier by pressing in the movement device switching element. For this purpose, it is in particular provided that the movement device switching element is a pin which can be pressed in through contact with the element frame when the door leaf is closed.

The movement device switching element is in particular arranged so that it is no longer pressed in when the door leaf is open. In this case, the sealing strip is preferably moved upwards relative to the seal carrier by means of a pull-in spring of the movement device.

The movement device preferably comprises a movement lever. This is preferably rotatably mounted on the seal carrier. The movement lever is preferably connected to a vertical rod. For example, the rod protrudes into an elongated hole in the movement lever. This means that the rod can at least be pushed down by turning the movement lever.

The retraction spring preferably sits on the rod, for example between the movement lever and the lower cross element of the seal carrier. The rod is preferably guided in a linearly movable manner in the lower cross element of the seal carrier. The rod is preferably connected to the sealing strip in order to move it.

The movement device switching element is preferably connected to the movement lever in such a way that the movement lever can be rotated by pressing in the movement device switching element.

The brake switching element and the movement device switching element are preferably arranged relative to one another in such a way that when the door leaf is opened, the brake switching element has transferred the brake to the braking state before the movement device has retracted the sealing strip into an end position.

The brake switching element and the movement device switching element are preferably arranged relative to one another in such a way that when the door leaf is closed, the brake switching element transfers the brake into the release state after the movement device has already extended the sealing strip at least partially, preferably completely. This is particularly true if the door leaf has previously been opened wide enough.

It is preferably provided that the brake switching element is designed and in particular arranged in such a way that when the driver and the raising/lowering unit meet, the brake is already in the release state.

The length of the brake switching element is preferably adjustable; in particular by means of a screwed-on sleeve.

The movement device switching element is preferably adjustable in length; in particular by means of a screwed-on sleeve.

Without the movable seal carrier and the associated brake, when the door leaf is closed via the movement device, the sealing strip is extended downwards and pressed against the floor under spring loading. However, the full stroke, for example 100 mm, would always have to be transmitted via the movement device switching element - regardless of the actual, momentary ceiling or floor deflection. At the same time, it should be noted that the sealing strip should only extend quite late when closing the door leaf, approximately at an opening angle of 10°, otherwise the sealing strip will drag on the floor. Not only would the large stroke path have to be managed via the movement device switching element, but the forces of the return and pressure springs also have to be overcome, so that a relatively large amount of work would have to be carried out. This would lead to undesirably high operating forces and high mechanical loads. In addition, a currently low ground clearance, for example with a correspondingly high snow load, would lead to the sealing strip coming into contact with the ground earlier during the closing process than with high ground clearance. This could make it very difficult to close the door leaf.

The seal carrier proposed within the scope of the invention, including the associated brake, enables the following advantages: When the door leaf is opened, the sealing strip is only raised by the required stroke. This stroke dimension can be 10 mm, for example. This means that the door leaf can always be opened and closed freely by the user. Due to this small stroke, only a correspondingly small amount of work has to be done when closing the door leaf, which is required to extend the sealing strip and press it against the floor under spring loading; this is done with the described Movement device. This leads to significantly improved ease of use compared to the state of the art. The user of the door experiences the same operating pressure every time the door leaf is used, regardless of the current ceiling deflection, for example in the range of 0 to 80 mm. This allows variable floor clearances of the door wall element or the entire mobile partition in the range of 20 to 100 mm.

If the ground clearance changes, for example due to a change in the ceiling or floor load, the raising and lowering unit also moves up or down. If the door leaf is closed, this movement is transmitted to the seal carrier via the driver, since when the door leaf is closed the driver rests on the raising/lowering unit and the brake is in the release state. In particular, this works in that the raising/lowering unit is always in contact with the floor via at least one further sealing strip (in particular sealing foot) in the element frame as soon as the door element for building the partition is set up at the appropriate location. If this additional sealing strip is pressed in when the ground clearance is reduced, the raising and lowering unit also moves upwards.

As soon as the door leaf is opened, the brake switching element lifts off the element frame and is no longer pressed in. This causes the brake to switch to the braking state and the seal carrier is fixed. Immediately following or simultaneously, the movement device is actuated by the movement device switching element also lifting off the element frame when the door leaf is opened, as a result of which the rod connected to the sealing strip is no longer pressed down, but is pulled in by the pull-in spring. However, a relatively small stroke, for example 10 mm, is sufficient because the sealing frame is basically adjusted to the current ground clearance via the driver. The door leaf can now be opened freely.

The brake, which switches to the braking state when the door leaf is opened, is an advantage so that the seal carrier and sealing strip do not fall towards the floor. When the door leaf is closed again, from a door leaf opening angle of approx. 10°, the sealing strip is actuated via the movement device and pushed down again. At the same time, the brake is released and the driver sits on the raising/lowering unit.

When the door element is dismantled, the sealing strip of the door leaf and the other sealing strips or sealing feet on the door element are completely retracted. The seal carrier in the door leaf is also moved upwards using the driver, since the door leaf is closed in this situation. All sealing strips and sealing feet are then completely retracted into the door element and the door element can be moved in the ceiling guide rail. The sealing strip on the door leaf side does not protrude from the door element in a disruptive manner.

The following situations are also taken into account within the scope of the invention: According to a first situation, the mobile partition is constructed, the current ceiling deflection is large and therefore the ground clearance is low and the door leaf is in the open state. If the ceiling rises, for example due to melting snow, this will lead to an increase in ground clearance while the door leaf is open. The sealing strip or sealing feet in the element frame would move further out of the door element and continue to press against the floor. This causes the raising/lowering unit to move downwards in the element frame. In this condition, the sealing strip of the open door leaf is slightly higher above the floor than necessary. When the door leaf is closed, the sealing strip together with the seal carrier falls down (because the brake is released) until the driver on the door leaf side is back on the element frame-side lifting/lowering unit rests. The door leaf can now be operated as already described.

In a second situation, it is assumed that the mobile partition has been constructed, the current ceiling deflection is small (the ground clearance is correspondingly large) and the door leaf is in the open state. If the ceiling drops while the door is open, for example due to snowfall, this will lead to a reduction in ground clearance. The sealing strip on the door leaf side including the seal carrier is then pressed through the floor into the door leaf. The braking force of the brake is exceeded so that the shift is even possible. Now the sealing strip is on the floor. In this special case, the user must close the door leaf once with the sealing strip pressed on. At the end of the closing process, the driver is lifted slightly upwards by the lifting/lowering unit; For this purpose, it is in particular provided that the driver has the inclined plane in order to be lifted by the lifting-lowering unit that is arranged too high up. The door can then be used normally again. In this special case, the open door leaf is protected from damage if the ceiling is lowered, as the mechanism for moving the sealing strip including the seal carrier gives way and the door leaf as a whole is not exposed to any damaging load.

The door element described here preferably includes a suspension at the upper end. This suspension can include, for example, trolleys or rollers. The door element can be hung on the ceiling guide rail of the mobile partition using the suspension.

The invention further includes a mobile partition with a ceiling guide rail and at least one of the described Door elements. The respective door element can preferably be hung on the ceiling guide rail, in particular it is hung.

The mobile partition preferably comprises one or more wall elements, which can also be suspended, in particular suspended, from the ceiling guide rail.

The following is based on the Fig. 1 to 6 a door element 1 of a mobile partition 100 described in detail. Fig. 6 shows purely schematically the mobile partition 100 with ceiling guide rail 101, on which several wall elements 102 and the door element 1 described in detail here hang. The door element 1 and the wall element 102 are along the Ceiling guide rail 101 movable from a stowed position to its extended position to form a partition in a room.

Fig. 1 shows the door element 1 with its one element frame 2. There are usually cover panels on both sides of the element frame 2, which are hidden here for the sake of clarity.

At the upper end of the element frame 2, suspensions 3 are provided in the form of trolleys, which are designed to guide the door element 1 in a linearly movable manner in the ceiling guide rail 101.

The door element 1 comprises a door leaf 4, which is rotatably connected to a lateral, column-like area of the element frame 2 via corresponding hinges 6. A gap 5 of a secondary closing edge is provided between the door leaf 4 and the laterally adjacent area of the element frame 2. The door element 1 has a sealing strip 17 and a sealing foot 27, which seal against a floor 200. The sealing strip 17 can be extended out of the door leaf 4. The sealing foot 27 can be extended from the element frame 2.

The door frame 7 of the door leaf 4 is shown. Corresponding cover plates can be applied to this door leaf frame 7, but these are hidden here for the sake of clarity. The door leaf frame 7 includes parallel vertical supports 9 and at least one cross support 8. The vertical supports 9 are connected to one another via the at least one cross support 8.

Figs. 2 and 3 show the in Fig. 1 marked details II and III. In Fig. 4 the door leaf frame 7, with the exception of a cross member 8, is hidden in order to show further details of the construction. Fig. 5 shows the in Fig. 4 marked section AA. Fig. 1 , 2 and 3 show the Sealing strip 17 in the lower end of the door leaf 4th in Fig. 4 the sealing strip 17 is hidden for the sake of clarity.

The following will focus on this in particular Fig. 1 to 5 Referenced:
There is a seal carrier 10 in the door leaf 4. In the exemplary embodiment shown, this seal carrier 10 has transverse elements 12 which are connected to one another via vertical elements 11. The vertical elements 11 connect the transverse elements 12. The vertical elements 11 penetrate one of the cross members 8. This cross member 8 of the door leaf frame 7 is located between the transverse elements 12.

The transverse elements 12 of the seal carrier 10 extend between the vertical supports 9 of the door leaf frame 7. On the front side of each transverse element 12 there is at least one guide roller 13 for the vertical, linearly movable guidance of the seal carrier 10 on the door leaf frame 7. The guide rollers 13 lie on the inside of the vertical support 9 of the door leaf frame 7.

Furthermore, the transverse elements 12 have guide extensions 14 at their front ends, which protrude into the adjacent vertical support 9.

There is a driver 15 on the seal carrier 10, in the exemplary embodiment on one of the vertical elements 11. The driver 15 projects into the gap 5. How in particular Fig. 4 shows, the driver 15 has an inclined plane 26.

A raising/lowering unit 16 is provided in the element frame 2, in particular in the column-shaped area of the element frame 2, which is located on the side of the door leaf 4. This raising and lowering unit 16 can also be referred to as a position sensor. The raising and lowering unit 16 is in movable in the vertical direction and moves in particular together with the sealing foot 27 of the element frame 2. If this sealing foot 27 is moved up or down when the ground clearance changes, the position of the raising-lowering unit 16 changes.

As explained in the general part of the description, when the door leaf 4 is closed, the driver 15 rests on this lifting-lowering unit 16, so that the seal carrier 10 can be moved upwards by the lifting-lowering unit 16.

In the event that the raising/lowering unit 16 is too high up when the door leaf 4 is closed, the driver 15 can be pushed upwards using the inclined plane 26.

For a downward movement of the seal carrier 10, an extension spring 25 is provided, which is tensioned between the seal carrier 10 and the door leaf frame 7. In the specific exemplary embodiment, the extension spring 25 is tensioned between the cross member 8 and the upper cross element 12.

The extension spring 25 can move the seal carrier 10 downwards when the door leaf 4 is closed until the driver 15 rests on the raising/lowering unit 16.

Furthermore, a brake 18 is provided. The brake 18 is arranged on the cross member 8 of the door frame 7. One of the vertical elements 11 of the seal carrier 10 protrudes through the brake 18. The brake 18 is designed to fix and release the seal carrier 10 relative to the door frame 7.

In particular the representations in the Figs. 4 and 5 illustrate the exact structure of the brake 18: The brake 18 includes a movable one Brake housing 19. A braking surface, here designed as a brake pad 20, is arranged on this brake housing 19, which can press against the seal carrier 10 (in particular vertical element 11). For this purpose, the brake housing 19 is connected to the door frame 7 (in particular cross member 8) via a pressure spring 21. This pressure spring 21 pulls the brake housing 19 and thus the brake pad 20 against the seal carrier 10.

Furthermore, the brake 18 comprises a rotatably arranged brake lever 22. The brake lever 22 is rotatably attached to the door leaf frame 7 (in particular cross member 8) via a first pivot bearing 23. A brake switching element 24 is connected to the brake lever 22, in particular in a rotatable manner. The brake switching element 24 protrudes into the gap 5 on the secondary closing edge and can be pressed in when the door leaf 4 is closed, as a result of which the brake housing 19 moves against the force of the pressure spring 21 and thereby releases the brake pad 20 from the seal carrier 10. This causes the brake 18 to enter the release state. In this state, when the driver 15 and the raising/lowering unit 16 meet, the position of the driver 15 can adapt to the position of the raising/lowering unit 16.

When the door leaf 4 is opened, the brake switching element 24 can move into the gap 5 due to the force of the pressure spring 21. As a result, the brake 18 is transferred to the braking state.

The sealing strip 17 is arranged on the seal carrier 10 via a movement device 30. The movement device 30 comprises a rod 34 on which the sealing strip 17 is arranged. This rod 34 projects upwards through the lower cross element 12 of the seal carrier 10, starting from the sealing strip 17.

Furthermore, the movement device 30 comprises a movement lever 31, which is rotatably mounted on the seal carrier 10 (in particular the lower cross element 12) via a second pivot bearing 32. The rod 34 projects into an elongated hole 33 of the movement lever 31, so that the rod 34 and thus the sealing strip 17 can be pressed downwards by turning the movement lever 31.

A pull-in spring 35, for example designed as a compression spring, is arranged on the rod 34. The pull-in spring 35 is supported on the one hand against the lower cross element 12 of the seal carrier 10 and on the other hand against the rod 34, so that the rod 34 can be moved upwards and relative to the seal carrier 10 by means of the pull-in spring 35.

The movement lever 31 is rotatably connected to a movement device switching element 36. The movement device switching element 36 projects into the gap 5 of the secondary closing edge and can be pressed in by closing the door leaf 4. As a result, the sealing strip 17 can be extended relative to the seal carrier 10.

When the door leaf 4 is opened, the pull-in spring 35 presses the movement device switching element 36 into the gap 5 via the movement lever 31. Here, the sealing strip 17 is retracted relative to the seal carrier 10.

Due to the door element 1 according to the invention, when the door leaf 4 is opened, the sealing strip 17 is only raised by a defined stroke, regardless of a movement of the seal carrier 10. The changed floor or ceiling loads are compensated for via the seal carrier 10. In particular, the seal carrier 10 can have a larger one Overcome the stroke as the movement device 30.
