Description

[0001] TITLE

[0002] SEALING DEVICE

[0003] TECHNICAL FIELD

[0004] The present invention relates to a sealing device for a door and a trigger module of such a sealing device.

[0005] STATE OF THE ART

[0006] Door seals are typically used in areas where light penetration is to be prevented and / or sound insulation is to be ensured. Door gap seals in the form of drop-down seals usually have a housing rail in the form of a U-shaped profile rail, a sealing strip with a sealing element held on or in this housing rail and movable relative to it, and a lowering mechanism for lowering and raising the sealing strip. The sealing strip usually lowers automatically when the door is closed by a force acting longitudinally on an actuating part protruding from the housing rail, actuating the mechanical lowering mechanism against a spring force. The actuating part is usually a rod or a bolt. When the door leaf is opened, the bolt is released again and the lowering mechanism raises the sealing strip again thanks to the restoring force of the springs.Such drop-down seals can be used not only on the underside of a door, but also on the vertical long sides of the door or on the top side of the door. The terms "lowering" and "raising" therefore refer to the housing rail and the stop surface for the sealing element's sealing engagement.

[0007] When pivoting doors close, the release pin rests against the stationary door frame and is pushed in as the door continues to close. With pivoting doors, the vertical pivot axis of the door leaf is located within the door leaf and not, as with other pivoting doors, in the hinge between the door frame and the door leaf. Therefore, when closing a pivot door leaf, different forces act on the release pin than with doors that pivot around an external pivot axis. The closing behavior is therefore different. Furthermore, when using a drop-down seal, wear is greater, particularly on the release pin and the door frame.

[0008] DE 102016108385 A1 discloses a mechanically operated drop-down seal for a pivot door. The drop-down seal comprises a housing and a trigger protruding from the front of the housing, with a rotatably mounted rotating body for engagement with a stationary stop surface. The rotating body is a ball or roller bearing whose axis of rotation runs perpendicular to the longitudinal direction of the drop-down seal and preferably parallel to the lowering direction of the sealing strip. The rotating body forms the free end of the rod-shaped trigger. A stationary stop surface is provided on the stationary frame, forming a ramp with a peak.

[0009] EP 3 667 010 A1 describes a stop device for a pivot door, wherein the stop device comprises a roller rotatably mounted in a roller carrier. The stop device is attached to the stationary frame of the door.

[0010] Furthermore, DE 202 19 081 U1 discloses a sliding door with a drop-down seal comprising a housing and a trigger pivotably mounted in the housing for actuating a mechanism for lowering a sealing strip. The trigger is designed as a lever element with a roller for contacting the stationary door frame.

[0011] KR 20130049928 A also describes a drop-down seal with a release lever and a roller arranged on it.

[0012] These known solutions are designed for doors with a single drop-down seal.

[0013] PRESENTATION OF THE INVENTION

[0014] It is therefore an object of the invention to provide a sealing device with two drop-down seals that can be used for pivot doors.

[0015] This object is achieved by a sealing device having the features of patent claims 1 and 33, respectively, and by a triggering module having the features of patent claims 21 and 22, respectively.

[0016] The sealing device according to the invention for a door with a pivoting door leaf has two drop-down seals for arrangement on or in the door leaf. The two drop-down seals are arranged next to each other and parallel to each other. Each of the two drop-down seals has a lowerable and raiseable sealing strip, a lowering mechanism for lowering and raising the sealing strip, and an actuating part, wherein the actuating part actuates the lowering mechanism when the door leaf is closed. The sealing device has a trigger module that acts on the two actuating parts when the door leaf is closed. The trigger module has a contact body that is designed to engage a stationary stop surface of the door and can be brought into contact with the stop surface when the door leaf is closed.

[0017] The two drop-down seals can thus be triggered with a common trigger module, so that their lowering mechanisms are activated together and, if possible, simultaneously. This enables a space-saving design of the sealing device, which allows the use of narrow door leaves. At the same time, it can be ensured that both drop-down seals are triggered with the same force. Since the trigger module acts on the actuating parts of the drop-down seals, the drop-down seals can still be individually adjusted from one another. In particular, the stroke or contact force relative to the stationary part can be individually adjusted. Adjustment is particularly simplified when the two actuating parts are longitudinally adjustable rods or bolts, as used in the prior art in combination with the known trigger buttons of drop-down seals.

[0018] The two drop-down seals are preferably identical. In other embodiments, however, they differ, for example, in their dimensions, particularly in their cross-section, and / or in the shape of the sealing profile and / or in the type of drop-down mechanism.

[0019] Preferably, the sealing strips of the two drop-down seals move in the same direction, i.e. they seal against the same surface or against similarly aligned surfaces.

[0020] In some embodiments, the module housing has a cuboid-shaped base body for receiving in a recess in the door leaf. In other embodiments, the base body of the module housing is circular-cylindrical for receiving in a circular-cylindrical recess in the door leaf. In this case, the receiving opening of the base body of the module housing, which slidably receives a base body of the force transmission body, is preferably also circular-cylindrical. Preferably, the base body of the force transmission body is also circular-cylindrical. In other embodiments, only the base body of the module housing is circular-cylindrical, but the base body of the force transmission body has a different cross-section, for example a rectangular cross-section. The receiving opening of the module housing is shaped such that it enables movement of the force transmission body received therein relative to it.

[0021] The circular-cylindrical design of the base body of the module housing allows for easy drilling of the mounting hole in the door leaf. The circular-cylindrical design of the base body of the force transmission body allows for a very space-saving design of the trigger module, thus enabling its use in narrow door leaves.

[0022] The contact body can be designed in different ways. In some embodiments, it is a sliding surface, which is preferably curved. In other, preferred embodiments, it is a rolling body, preferably a roller. The term "roller" in this text also includes a wheel or the like. These terms are understood as synonyms.

[0023] The roller, especially when used in pivot doors, has the advantage of optimally following the closing and opening movement of the door leaf, thus enabling optimal power transmission with minimal wear. This is especially true when the rolling element, especially the roller, can rotate around an axis that extends perpendicular to the longitudinal direction of the two drop-down seals.

[0024] The trigger module can be designed in different ways. It is preferably symmetrical with respect to the two drop-down seals and uses identical components to actuate the two actuating parts of the drop-down seals. This ensures that both drop-down seals are triggered as simultaneously as possible and with the same force transmission. However, an asymmetric design of the drop-down seal is also possible, especially when used with two different drop-down seals.

[0025] The trigger module preferably has a force transmission body that is movable relative to the door leaf when closing. The contact body is preferably arranged on the force transmission body. This enables optimal force transmission to the two actuating parts.

[0026] In some embodiments, the force transmission body is pivotable or performs a complex movement. Preferably, however, it is movable in the longitudinal direction of the two drop-down seals. It is preferably movable exclusively in this longitudinal direction. This optimizes force transmission and shortens the travel distance. This allows for the design of very space-saving trigger modules.

[0027] Preferably, the force transmission body is firmly connected or connectable to the two actuating parts when assembled, or it merely contacts the force transmission parts. The fixed connection enables play-free force transmission in both directions, i.e., when lowering and raising the sealing strips. Depending on the design, the contact enables faster lifting of the sealing strips when opening the door leaf.

[0028] The force transmission body can be guided and movable directly on or in the door leaf and / or on or in at least one of the two drop-down seals. Preferably, however, the force transmission body is held in a module housing, wherein the module housing can be fastened on or in the door leaf or to at least one of the two drop-down seals. The module housing is preferably fixed in position relative to the door leaf. The force transmission body is movable relative to the module housing when the door leaf is closed and preferably also when it is opened. The use of a module housing has the advantage that the dimensional accuracy requirements for accommodating the trigger module on the door leaf are not too high. The same trigger module can also be used in door leaves of different designs.

[0029] To ensure the most optimal movement of the force transmission body with minimal friction, it is designed accordingly. In some embodiments, it has at least one sliding surface, which enables movement relative to the door leaf. Preferably, there is a sliding surface on each of two opposite side walls of the force transmission body. In other preferred embodiments, the force transmission body has at least one rotating body on at least one side, preferably on two opposite sides, which enables movement relative to the door leaf. Preferably, the at least one rotating body is a ball and / or a roller.

[0030] The operative connection between the trigger module and the two actuating parts of the two drop-down seals can be established in different ways. It can be direct or indirect, fixed, or simply by contact. Preferably, the trigger module has a connecting element for contacting each of the two actuating parts or for connecting to each of the two actuating parts. The connection is preferably fixed, but preferably detachable for disassembly. The two connecting elements are preferably arranged on the force transmission body. The two connecting elements are preferably two connecting pins.

[0031] In some embodiments, the connecting elements are fixedly or detachably connected to the force transmission body, with only one position being provided for each connecting element.

[0032] In other embodiments, the force transmission body has at least two receptacles for each connecting element for selective connection to the force transmission body, wherein the at least two receptacles are arranged one behind the other in the longitudinal direction of the two drop-down seals. This increases flexibility during installation and also facilitates use with rebated doors.

[0033] Preferably, the two connecting elements are arranged or can be arranged offset from each other in the longitudinal direction of the two drop-down seals. This also enables use with rebated doors.

[0034] In a preferred embodiment, a first of the two connecting elements protrudes from the force transmission body on a first side, and a second of the two connecting elements protrudes from the force transmission body on a side opposite the first side. In this case, the trigger module can be made extremely small and easily mounted in the door leaf. In preferred embodiments, the connecting elements run perpendicular to the direction of movement of the force transmission body relative to the module housing and extend perpendicularly away from the force transmission body.

[0035] Preferably, the connecting elements run perpendicular to the longitudinal direction of the two drop-down seals.

[0036] Preferably, the trigger module is arranged between the two lowering seals.

[0037] The trigger module according to the invention is thus designed to act on the two actuating parts of the sealing device when the door leaf is closed. It comprises a contact body designed to engage a stationary stop surface of the door and can be brought into contact with the stop surface when the door leaf is closed.

[0038] It is a further object of the invention to provide an alternative to activating a drop-down seal in the longitudinal direction of the drop-down seal.

[0039] This object is achieved by a trigger module having the features of claim 22 and a sealing device having the features of claim 33.

[0040] The inventive trigger module of a sealing device for a door with a pivoting door leaf has at least one drop-down seal for arrangement on or in the door leaf. The at least one drop-down seal has a lowerable and raiseable sealing strip, a lowering mechanism for lowering and raising the sealing strip, and an actuating part, wherein the actuating part actuates the lowering mechanism when the door leaf is closed. The trigger module has a module housing and a force transmission body, wherein the module housing can be fastened on or in the door leaf or to at least one of the at least one drop-down seal. The force transmission body is arranged in the module housing and is movable relative to the module housing, thereby defining a direction of movement.The trigger module has a contact body that is designed to bear against a stationary stop surface of the door and can be brought into contact with the stop surface when the door leaf is closed. The contact body is arranged on the force transmission body. The trigger module has a connecting element for each of the at least one drop-down seals for contacting the actuating part or for connecting to the actuating part. The connecting element runs perpendicular to the direction of movement of the force transmission body and is arranged on this force transmission body. It projects from this, whereby the force transmission body and the module housing are designed to be laterally offset with respect to the at least one drop-down seal (1) transversely to the direction of movement.

[0041] In some embodiments, the trigger module has only a single connecting element for connecting to a single drop-down seal. In other embodiments, it has two or exactly two connecting elements, each connecting to a drop-down seal.

[0042] Preferably, the two connecting elements are arranged on opposite sides of the force transmission body.

[0043] The optional and preferred features specified above for achieving the first object of the invention can also be combined with the above-described trigger modules and the above-described sealing devices, providing the same advantages. This is true even if the features are adopted only for use with a single drop-down seal. The features of dependent claims 2 to 20 thus also apply to the trigger module and the sealing device according to claims 22 to 35, even if reduced to a single drop-down seal.

[0044] Further embodiments are specified in the dependent claims.

[0076] DESCRIPTION OF PREFERRED EMBODIMENTS

[0077] Figure 1 shows a building situation with a wall W in which a pivot door with a pivoting door leaf T is arranged. As can be seen in Figure 1, the door pivot axis D is located in the door surface. In the lower end face of the door leaf T, a groove for a sealing device with two drop-down seals 1 is formed. In other embodiments, additionally or alternatively, a groove N and a sealing device S arranged therein are present on the upper end face and / or the lateral end faces of the door leaf T. Instead of being arranged in a groove N, the sealing device S can also be fastened to the outside of the door leaf T.

[0078] Depending on the design, the wall W itself forms the frame for the door leaf or there is a frame that is arranged in the wall opening.

[0079] Figures 2 to 7 show a first embodiment of the sealing device according to the invention.

[0080] Figures 2 and 3 show the wall W and part of the door leaf T. In Figure 3, the door leaf T is closed in Figure 3, and in Figure 2 it is in a state during the closing of the door. The embodiments shown in the other figures are also preferably arranged in this way on or in the door leaf T and preferably have the drop-down seals 1 described below. The sealing device S has two drop-down seals 1 arranged in the groove N of the door leaf T. The drop-down seals 1 are preferably seals of a known type. They can be identical or different. The drop-down seals 1 shown are preferred but should be understood as merely examples. Each of the two drop-down seals 1 has, as can be seen in Figure 6, a housing profile rail 10 with a U-shaped cross-section that is open downwards.A sealing strip is mounted on or in the housing profile rail 10, which can be moved relative to the housing profile rail 10 in a direction perpendicular to the longitudinal direction of the sealing strip and thus also of the housing profile rail 10. It can thus be raised and lowered. The sealing strip is connected to the housing profile rail 10 via a lowering mechanism. The lowering mechanism is designed differently depending on the specific embodiment. It preferably comprises return springs 14, for example, leaf springs, and a slider 15 extending in the longitudinal direction. This lowering mechanism is known in the art. Alternative lowering mechanisms can also be used.

[0081] An example of a drop-down seal with a drop-down mechanism is shown in Figures 29 and 30.

[0082] The sealing strip comprises a support profile rail 12 and a sealing profile 11 formed or attached to it. The sealing profile 11 extends at least the entire length or height of the door leaf T and, when the sealing strip is lowered, forms a seal against the floor, ceiling, or side door frame. In this example, the device seals downwards against the floor.

[0083] An actuating part 13 protrudes from the front of the support profile rail 12 and / or the housing profile rail 10. The actuating part 13 is preferably designed in the form of a bolt or a rod. Depending on the embodiment, it is hollow or solid. It preferably has an external or internal thread for connection to the slide 15. It is preferably adjustable with respect to the lowering mechanism, in particular with respect to the slide 15. The adjustability can be achieved, for example, via a threaded connection, so that the extent to which the actuating part 13 protrudes from the front can be selected.

[0084] The actuating part 13 acts via the connection with the slide 15 on the lowering mechanism, here on the return springs 14. If the actuating part 13 is pressed in the direction of the housing profile rail 10, the lowering mechanism lowers the sealing strip, preferably against the spring force of the return spring 14. If the external pressure on the actuating part 13 is removed, ie the actuating part 13 is released again, the sealing strip is raised again due to the restoring force of the return spring 14.

[0085] The sealing profile 11 preferably projects beyond the support profile rail 12 and preferably also beyond the housing profile rail 10. Depending on the design, the sealing profile 11 can be extended by "massaging" it out, or it is designed to be expandable or extendable in another way. When the door is closed, it preferably forms a seal against the vertical door frame or casing, thus forming not only a seal against the floor but also a seal against the front.

[0086] The sealing device further comprises a trigger module 2, as can be seen in Figures 2 and 3. The trigger module 2 is preferably also arranged in the groove N of the door leaf T. It is preferably located centrally between the two drop-down seals 1.

[0087] In this exemplary embodiment, the groove N of the door leaf T is provided with a step A, as can be clearly seen in Figures 5 and 6. The groove N thus forms two parallel channels, open at the bottom, each for receiving one of the drop-down seals 1. At one end of the groove N, the two channels are connected in their upper region by a cuboid-shaped recess, so that a step A is formed towards the open lower end of the door leaf T. This recess forms a receiving opening for the trigger module 2. The trigger module 2 thus rests on the step A in the assembled state, as can be clearly seen in Figure 4.

[0088] The trigger module 2 has, as can be seen in Figures 6 and 7, a module housing 4, a force transmission body 5, a rotation body, here in the form of a roller 6, and two connecting elements, here in the form of connecting pins 7.

[0089] The module housing 4 has a flat, cuboid-shaped base body with a flat lower wall 40, a flat upper wall 41 running parallel thereto, two side walls 42, and a rear wall 43. The narrow front end of the base body is open, so that a receiving opening 44 is formed for receiving the force transmission body 5. In this embodiment, the rear wall 43 has through-hole fastening openings 47 on the rear side. This allows the module housing 4 to be screwed to the rear wall of step A using screws (not shown here), thus securely fixing it in place in the door leaf T.

[0090] The side walls 42 each have an open lateral groove 45 in the front region of the base body, which extends in the longitudinal direction of the side walls 42 and thus also in the longitudinal direction of the drop-down seals 1. These two grooves 45 are open toward the front face of the base body. The two grooves 45 each merge into an inner lateral recess 46. The two inner lateral recesses 46 extend over the remaining length of the side walls 42 to the rear wall 43. However, they are closed with respect to the respective side wall 42. These lateral recesses 46 are preferably rounded.

[0091] The force transmission body 5 preferably also has a flat, cuboid-shaped base body 50. The base body 50 is shorter than the module housing 4. It is received in the receiving opening 44 of the module housing 4 and is displaceable within the module housing 4 in the longitudinal direction of the drop-down seals 1. The possible displacement path within the module housing 4 preferably corresponds at least to the displacement length of the actuating parts 13 of the drop-down seals 1. Or, to put it another way: it preferably corresponds at least to the distance by which the actuating parts 13 are pressed in toward the door leaf when the door leaf is closed in order to actuate the drop-down mechanism. The two lateral open grooves 45 also have a length that corresponds at least to this distance.

[0092] A fork-shaped nose 54 is formed on the front end of the base body 50, which holds the roller 6. The roller 6 is mounted in the force transmission body 5 so as to be rotatable about an axis 55. The axis 55 preferably runs perpendicular to the longitudinal direction of the two drop-down seals 1 and parallel to the drop-down direction of the sealing strip.

[0093] Inside the base body 50, here in a receiving opening 51, rotating bodies 52, in this case rollers, are arranged, projecting laterally. Preferably, such rollers project on the two opposite sides of the base body 50. Their axes of rotation 56 run parallel to the axis 55 and parallel to the direction of movement of the sealing strip of the drop-down seals 1.

[0094] The rotating bodies 52 rest against the two inner lateral recesses 46 of the module housing 4 and roll in these recesses 46 as the force transmission body 5 is moved. This enables optimal guidance of the force transmission body 5 when the door leaf T is closed and opened.

[0095] In the front area of ​​the base body 50, a connecting element in the form of a connecting pin 7 is arranged in each side wall. For this purpose, the two side walls each have a lateral receiving opening 53. The connecting pins 7 protrude laterally from the side walls. Preferably, they protrude at a right angle. Each connecting pin 7 has a free end 70 that can be connected to one of the two actuating elements 13. During assembly, it is preferably fixedly but detachably connected to the free end of the actuating element 13. In this embodiment, the rod-shaped actuating element 13 has a slot 130 for the positive and / or non-positive reception of the free end 70 of the connecting pin 7. Other contact or connection types are also possible.

[0096] When the door leaf T closes, the roller 6 rolls along the frame and the force transmission body 5 is pressed into the module housing 4. This can be seen by comparing Figures 2 and 3. Due to their operative connection with the connecting pins 7, the two actuating parts 13 are also pressed into the respective housing profile rail 10. They activate the lowering mechanism, which lowers the sealing strip, i.e., the support profile 12 and the sealing profile 11. The sealing profile 11 seals the gap between the underside of the door leaf and the floor.

[0097] When the door is opened again, roller 6 slides along the frame. The force acting on force transmission body 5 is eliminated. The return force of the return springs of the lowering mechanism can thus lift the sealing strip and push the actuating parts 13 outward again. The actuating parts 13 take the connecting pins 7 and thus the force transmission body 5 with them. The sealing device is ready for the next use.

[0098] Figures 8 to 12 show a second embodiment of the trigger module 2 according to the invention. It is essentially identical to the previously described example. It can be coupled to the two drop-down seals 1 in the same way. Only the module housing 400 has some changes. In contrast to the first example, it can also be fastened from below in the groove N or on the underside of the door leaf T. Fastening takes place, as in the first example, before the force transmission body 5 is inserted into the module housing 400. The module housing 400 according to this example has large lower through-holes 49 in the lower wall 40 and aligned upper fastening holes 48, preferably with a countersink, in the upper wall 41.The lower through-openings 49 are used for the introduction of screws (not shown) and for the passage of the screwdriver for fastening the screws passing through the fastening holes 48 in the groove N of the door leaf T.

[0099] The rear mounting holes 47 are also present in this example, allowing you to choose which mounting type to use. However, they can also be missing.

[0100] Figure 10 shows the assembled trigger module 2. Figure 11 clearly shows the connection between connecting pins 7 and actuating parts 13. Figure 12 shows the entire sealing device, ie, with the two lowering seals 1.

[0101] Figures 13 and 14 show a third embodiment of the sealing device according to the invention. The difference from the previous examples lies again in the design of the module housing 401. It is not flat, but rather has a height that preferably corresponds to the depth of the groove N of the door leaf T and / or the height of the housing profile rail 10. This allows a groove to be formed in the door leaf that has the same rectangular cross-section over its entire length. This simplifies the manufacture and processing of the door leaf T.

[0102] The module housing 401 can be secured using rear mounting holes 46 and / or upper mounting holes 48 in combination with lower through holes 49. Alternatively, it can also be glued into the groove N or to the underside of the door leaf T.

[0103] Figure 15 shows a flat module housing 402 that has no mounting holes and can also be glued in place. Figure 16 shows another embodiment of a force transmission body 500. It can be used with other module housings described in this text. However, these module housings preferably do not have internal lateral recesses 46; instead, the inner surface of the side walls 42 is flat.

[0104] The force transmission body 500 according to this embodiment does not have any laterally arranged rotational bodies. At least one region of the walls, preferably the side walls 58, of the base body 50 is designed as a lateral sliding surface that slides along the inner surface of one of the side walls 42 of the module housing 402. Preferably, both opposing side walls 58 of the force transmission body 500 are designed such that they slide along both side walls 42 of the module housing 402. This guides the movement of the force transmission body 500 within the module housing 402.

[0105] In a further embodiment according to Figure 17, the rotating bodies are not rollers, but balls 8, which are arranged in depressions 57 in the side walls 58 of the base body 50 of the force transmission body 501.

[0106] Figures 18 to 22 show a further embodiment. It is essentially constructed in the same way as the embodiments already described above.

[0107] The main differences lie in the design of the force transmission body 502 and the arrangement of the two connecting pins 7.

[0108] The two connecting pins 7 are arranged offset from one another in the longitudinal direction of the trigger module 2 and the sealing device S, or they can be arranged offset from one another. For this purpose, the force transmission body 502 has at least two, here three, lateral receiving openings 53 on both longitudinal sides. The connecting pins 7 can be arranged optionally in one of the lateral receiving openings 53. Depending on the selected position, the two connecting pins 7 lie on a common line and are thus not offset, or they are offset from one another, as is the case in Figure 19.

[0109] Furthermore, the side walls 58 of the force transmission body 502 are curved outward, i.e., convex. This is the case at least in the area where there are no receiving openings 53. In this example, the rounded side walls 58 extend over the entire length of the base body 50, with the area around the receiving openings 53 being flat and thus forming a recess in the corresponding side wall 58.

[0110] The module housing 403 preferably has corresponding concave, inner lateral recesses, as shown in the embodiments according to Figures 14 and 15 and provided with the reference numeral 46. They preferably transition seamlessly into the open lateral grooves 45.

[0111] Preferably, the base body 50 of the force transmission body 502 has a recessed top surface and a likewise recessed bottom surface relative to the rounded side surfaces 58. This optimizes the guidance and sliding properties of the force transmission body 502 in the module housing 503.

[0112] Thanks to its offset arrangement, this release module can be used for rebated doors. This is clearly visible in Figures 20 to 22. Reference symbol R in Figure 22 denotes a door frame, and reference symbol F denotes a door rebate seal.

[0113] The door is, for example, a pivot door, i.e. a door in which the pivot axis of the door leaf runs within the door leaf, or a pivoting hinged door with a pivot axis located outside the door leaf surface and at the front of the door leaf.

[0114] Thanks to the offset connecting pins 7, the offset lowering seals 1 with their respective actuating parts 13, here bolts, can be actuated together with the same trigger module 2.

[0115] If there are multiple fastening positions for the two connecting pins 7 in the longitudinal direction, the same trigger module 2 can be used for different door shapes. In particular, it can also be used for non-rebated doors, such as those shown in Figures 4, 13, and 16.

[0116] This variable fastening option can also be implemented in the other embodiments described here. For example, the other force transmission bodies 5, 500, 501, 503 described in this text can also be provided with a corresponding plurality of lateral receiving openings for the connecting pins 7. Instead of a variable fastening option, the two fastening pins 7 can be arranged offset from one another in the longitudinal direction in all embodiments described here.

[0117] The force transmission body 502 and the module housing 503 of the embodiment according to Figures 18 to 22 can be configured with sliding flat side walls or with balls or rollers as described in the other embodiments instead of with sliding curved side walls. The other embodiments can also be configured with the force transmission body 502 and the module housing 503 according to Figures 18 to 22, in particular with the rounded side surfaces 58 and / or the multiple lateral receiving openings 53.

[0118] The fastening of the trigger module 2 according to Figures 18 to 22 is preferably carried out as described in the other embodiments.

[0119] Figures 23 to 28 show a further embodiment of a sealing device S in which the trigger module 2 is operatively connected to a single lowering seal 1.

[0120] The drop-down seal 1 is designed as described above and preferably has a housing profile rail 10 arranged in the groove N of the pivoting door leaf T. The sealing strip comprises the support profile rail 12 and the sealing strip 11 arranged thereon. The sealing strip is movable relative to the housing profile rail 10 perpendicular to the longitudinal direction of the housing profile rail 10 by actuating the actuating part 13. The actuating part 13 is again a bolt or a rod. The arrangement can seal downwards against a floor, as shown in Figures 23 and 24, or can seal upwards if the drop-down seal is arranged on the upper end face of the door leaf T. A lateral seal is also possible if the drop-down seal is arranged on a vertical end face of the door leaf. This also applies to the other drop-down seals 1 described here.

[0121] The trigger module 2, in turn, has the roller 6, which rolls along the wall W or the door frame R when the door is closed and is thereby inserted into the module housing 404. The actuating part 13 is pressed in by means of the connecting pin 7, whereby the sealing strip 11, 12 is lowered. Figures 23 and 25 show the drop-down seal 1 with the sealing strip not actuated and raised. In Figures 24 and 26, the roller 6 has already been pressed in, and the sealing strip 11, 12 has thus been moved downward relative to the housing profile rail 1. In Figure 24, it has been partially lowered, and in Figure 26, it has been completely lowered.

[0122] The trigger module 2 is clearly visible in Figure 27. The module housing 404 is designed as a circular-cylindrical tube with a lateral slot or an open lateral groove 45. The force transmission body 503 has a base body 50 with a correspondingly round cross-section. The base body 50 is accommodated in the module housing 404 in a guided, longitudinally displaceable manner.

[0123] The force transmission body 503 has a fork-shaped nose 54 formed integrally with the base body 50. The nose 54 holds the roller 6, which is rotatable about the axis 55 running perpendicular to the longitudinal direction of the sealing device. In the unactuated state of the drop-down seal 1, the roller 6 protrudes from the module housing 404.

[0124] The force transmission body 503 is preferably solid, i.e., not hollow. It has at least one receiving opening 53 extending transversely to the axis 55 for receiving the connecting pin 7. Preferably, as shown here, several receiving openings 53 are arranged one behind the other in the longitudinal direction of the force transmission body 503 or the sealing device S, so that various connection options are available for connection to the actuating part 13. This increases the flexibility when mounting the sealing device S in a door, so that, for example, the stroke of the sealing strip can be adjusted or the arrangement can be better adapted to the shape of the door.

[0125] The connecting pin 7 is connected to the actuating part 13 at its free end. Depending on the design, the connection is fixed, detachable, or loose. The connecting pin 7 runs transversely to the axis 55 and transversely to the longitudinal direction of the sealing device S or the drop-down seal 1.

[0126] Figure 28 shows the recess which is preferably provided in the door leaf T for accommodating the trigger module 2. It has a cuboid-shaped groove N which is open towards the upper or lower end face of the door leaf and which preferably extends over the entire length of the door leaf T. The groove also has a short shoulder A which serves to accommodate the connecting pin 7 and whose length is selected according to the possible movement of the connecting pin 7 in the longitudinal direction. The shoulder A merges into a circular-cylindrical opening O whose length is selected according to the length of the trigger module 2.

[0127] The design of this release module 2 has the advantage that a round hole can be drilled instead of a rectangular recess. This simplifies production and reduces costs, especially for wooden door leaves.

[0128] Instead of a one-sided release for a single drop-down seal, this design can also be configured on both sides to activate two drop-down seals. The circular-cylindrical force transmission body 503 can be provided with connecting pins 7 on two opposite sides for the simultaneous activation of two drop-down seals 1.

[0129] Furthermore, the double-sided triggering modules 2 described above can also be designed to be single-sided, by allowing a connection to a connecting pin 7 on only one side or by being provided with a connecting pin 7 on only one side.

[0130] In an embodiment not shown here, the same door leaf is provided with two drop-down seals 1, wherein a first of the drop-down seals 1 on a first vertically extending end face of the door leaf is triggered by a first triggering module 2 and wherein a second of the drop-down seals 1 on the opposite second vertical end face of the door leaf is triggered by a second triggering module 2. This can be achieved in particular with the embodiment according to Figures 23 to 28. However, the other described embodiments are also suitable for this purpose, in particular, but not exclusively, if they are designed to trigger only one drop-down seal 1.

[0131] The device according to the invention enables optimized operation of two drop-down seals, particularly in pivot doors.
