DESCRIPTION OF THE INVENTION

[0055] FIG. 1 shows a building situation with a wall W, in which a pivot door with a pivotable door leaf T is formed. As can be seen in FIG. 1, the door pivot axis D is located in the door surface. A groove for receiving a seal device S is formed in the bottom end face of the door leaf T. In other embodiments, a groove and a seal device S arranged therein are alternatively or additionally present on the top end face and/or the lateral end faces of the door leaf T. Instead of arrangement in a groove, the seal device S can also be fastened on the door leaf T.

[0056] Depending on the embodiment, the wall W itself forms the frame for the door leaf, or a case arranged in the wall opening is present.

[0057] FIGS. 2 to 16 illustrate a first embodiment of the seal device according to the invention, with FIG. 13 showing a variant.

[0058] FIGS. 2 and 3 show the wall W and part of the door leaf T. In FIG. 3 the door leaf T is closed and in FIG. 2 it is in a state while the door is being closed.

[0059] The seal device has a drop-down seal, which is arranged in a groove of the door leaf T. The drop-down seal is preferably a seal of the known type. The drop-down seal illustrated in FIGS. 4, 5 and 7 is preferred, but is to be understood merely as an example. It comprises a housing profile rail 1 with a U-shaped, downwardly open cross section. A sealing strip is held on or in the housing profile rail 1 and can be moved relative to the housing profile rail 1 in a direction perpendicular to the longitudinal direction of the sealing strip and thus also of the housing profile rail 1. It can thus be raised and lowered. The sealing strip is connected to the housing profile rail 1 via a lowering mechanism 4. The lowering mechanism has a different design depending on the embodiment. It preferably has leaf springs and a longitudinally extending slide. This lowering mechanism is known in the prior art. Alternative lowering mechanisms can likewise be used.

[0060] The sealing strip has a carrier profile rail 2 and a sealing profile 3 integrally formed or fastened thereon. The sealing profile 3 extends at least over the entire length, or height, of the door leaf T and rests sealingly on the floor, the ceiling or the lateral door frame when the sealing strip has been lowered. In this example, the device provides downward sealing with respect to the floor.

[0061] An actuating part 5 protrudes beyond the end face of the carrier profile rail 2 and/or the housing profile rail 1. The actuating part 5 preferably has a main body 50 in the form of a bolt or a rod. It is preferably made from plastic. As an alternative, it consists for example of metal. It acts on the lowering mechanism 4. If it is pressed in towards the housing profile rail, the lowering mechanism 4 lowers the sealing strip, preferably counter to the spring force. If the pressure on the actuating part 5 is stopped, i.e. the actuating part 5 is rereleased, the sealing strip is raised again owing to the restoring force of the springs.

[0062] FIGS. 4, 7 and 8 illustrate an adapter part 7 which can optionally be used. It has a base body 70 with a substantially rectangular cross section and two pins 71, 72, which extend in the longitudinal direction of the base body 70 and are integrally formed on the upper part of the base body 70. The pins 71, 72 preferably have an approximately rectangular cross section.

[0063] A first one 71 of these two pins can preferably be inserted above the carrier profile rail 2, and a second one 72 of the two pins can preferably be inserted into a receiving opening 20 in the carrier profile rail 2. This can be seen in FIG. 7. As a result, the adapter part 7 forms an end-face extension of the carrier profile rail 2.

[0064] A respective receiving groove 73, 74 is formed in the two opposing side walls of the base body 70, wherein the two receiving grooves 73, 74 are arranged one above the other or next to each other depending on the embodiment. They are in line with the receiving grooves of the carrier profile rail 2 and serve, like the grooves in the carrier profile rail 2, to fasten the sealing profile 3.

[0065] If the carrier profile rail 2 has a different shape, the adapter part 7 is designed to match it.

[0066] The sealing profile 3 preferably protrudes beyond the carrier profile rail 2. Depending on the embodiment, the sealing profile 3 can be extended by kneading out or it is designed such that it can be expanded or extended in another way. The sealing profile 3 is preferably made of silicone or another elastomer material. It may be in one part or multiple parts, with the one-part form being preferred.

[0067] By considering FIGS. 5 and 7 together, it can be seen that the sealing profile 3 protrudes beyond the carrier profile rail 2 and the housing profile rail 1. As a result, when the adapter part 7 has been inserted, the sealing profile also extends over the entire length of the adapter part. It also preferably protrudes beyond the end side of the adapter part 7, with the result that it sealingly abuts the vertical door frame, or the case, when the door leaf is closed. That is to say, it forms an end-side seal.

[0068] The seal device also has a triggering module 8, as can be seen in FIGS. 2 and 3. The triggering module 8 is arranged in a recess A in the door leaf T. The recess A is preferably located on the end side next to the groove that receives the housing profile rail 1.

[0069] The triggering module 8 can be clearly seen in FIGS. 6, 9 and 10. It has a pivot arm 80. A receiving opening 801 is present on an end face of a first end of the pivot arm 80. A fork-shaped first recess 805, which is delimited by two first through-openings 802 that are in line with one another, is present at the opposite, second end of the pivot arm 80. A fork-shaped second recess 800, which is delimited by two second through-openings 803 that are in line with one another and two third through-openings 804 that are in line with one another, is present between the first and the second end.

[0070] The triggering module 8 also comprises a first fixing part 82 with a fastening opening 821. The first fixing part 82 can be fastened in the recess A of the door leaf T by means of a first screw 83.

[0071] The first fixing part 82 also has a plate with a fourth through-opening 820. The plate can be inserted into the fork-shaped first recess 805 and fixed by means of a bolt or a second screw 85, with the result that the pivot arm is fastened in the recess A of the door leaf T pivotably relative to the first fixing part 82.

[0072] A wheel 81 is rotatably fastened in the second recess 800 of the pivot arm 80. For this, it has a central through-opening 810 through which a third screw 86 passes. The wheel 81 is thus rotatably fixed. To this end, the third screw 86 is screwed either in the second through-openings 803 or in the third through-openings 804.

[0073] A connecting pin 84 is arranged in the receiving opening 801. At its free end 840, the connecting pin 84 has coupling means for connection to the actuating part 5. The coupling means is preferably a snap-fit element for snap-fitting into a slot 51 of the actuating part 5. The snap-fit element is, for example, a resilient fork.

[0074] The slot 51 is preferably integrally formed on the free end of the main body 50. It is delimited towards the free end preferably by means of inwardly projecting lugs 52. Depending on the embodiment, lugs 52 are present only on one side of the slot 51, as illustrated in FIG. 12, or lugs 52 are present on either side.

[0075] As can be seen in FIGS. 12 and 13, a bore 53 which is accessible through the slot 51 from the outside is present in the main body 50.

[0076] FIG. 11 illustrates that the position of both the actuating part 5, i.e. the bolt, and the connecting pin 84 can be changed. For example, the connecting pin 84 can be screwed into the pivot arm 80 to a greater or lesser extent by means of a screwdriver 90. The actuating part 5 can, for example, be screwed into the housing rail 1 to a greater or lesser extent by means of an Allen key 91. By changing the extent to which the actuating part 5 protrudes, the travel of the sealing strip can be changed. Changing the extent to which the connecting pin 84 protrudes enables connection to the actuating part 5 irrespective of its set position.

[0077] In FIGS. 2 and 3, it can now be seen that the wheel 81 rolls on the door frame, or the case, when the door leaf T is being closed and the pivot arm 80 moves into the recess A in the door leaf T. In the process, the pivot arm 80 pushes the actuating part 5 into the drop-down seal by virtue of the connection. The lowering mechanism is actuated and the sealing strip, i.e. the carrier profile rail 2 and the sealing profile 3, and the adapter part 7 are lowered. When the door is being opened, the opposite movements take place, since the sealing strip is raised owing to the restoring force of the springs and the actuating part 5 is pushed outwards.

[0078] In FIGS. 2 and 3, the connecting pin 84 is screwed into the pivot arm 80 to a relatively great extent; in FIG. 14, it protrudes further.

[0079] In FIGS. 2, 3 and 14, the wheel 81 is fastened in the second through-openings 803 and thus pivots about a first pivot axis 880. The pivot axis 89 of the pivot arm 80 is defined by the first through-openings 802.

[0080] In FIGS. 15 and 16, the pivot arm is rotated about its longitudinal axis by 180?. Now, it is not the second through-openings 803 but the third through-openings 804 which are closer to the door frame. The third screw 86 passes through the third through-openings 804 for the purpose of fastening the wheel 81, with the result that the wheel 81 rotates about a second axis of rotation 881.

[0081] The choice of the position of the wheel 81 in relation to the pivot axis 89 thus enables further adaptation to the local conditions. This enables optimum actuation of the drop-down seal and protects the door frame.

[0082] In the exemplary embodiment described, the housing profile rail 1 is preferably arranged recessed in the door leaf T. The actuating part 5 preferably does not protrude beyond the door leaf. Except for the wheel 81, preferably no components protrude beyond the lateral end face of the door leaf T, or they only minimally protrude beyond the end face. The drop-down seal is also fastened in the door leaf T independently of the triggering module 8.

[0083] In the embodiment according to FIG. 17, the triggering module 8 moreover serves to fasten the drop-down seal, preferably the housing profile rail 1, in the door leaf T. To this end, the triggering module 8 instead of the first fixing part 82 has a second fixing part 87, which fastens both the pivot arm 80 in the door leaf T and the housing profile rail 1 in the door leaf T. A first tab 871, which can be pushed into the U-shaped housing profile rail 1 below a fin of the latter and thus holds the drop-down seal, is preferably present.

[0084] The second fixing part 87 is preferably in the form of a plate with fastening openings 870 for screwing onto the end face or into the recess A of the door leaf T. The first tab 871 and two second tabs 872 are integrally formed on this plate 87. The second tabs 872 are arranged parallel to and spaced apart from one another and they each have a through-opening 873, which are in line with one another, for receiving the second screw 85, in order to pivotably hold the pivot arm 80. A connecting pin 84, which is, however, not illustrated in FIG. 17, is preferably also present in this embodiment. In this embodiment, the pivot arm 80 can be connected to the second fixing part 87 only in one position. In other embodiments, however, the pivot arm 80 has the same design as in the first exemplary embodiment, such that the wheel 81 can be used in two different positions with respect to the pivot axis 89.

[0085] The triggering module in the embodiment shown in FIGS. 18 and 19 is designed to save space thanks to the angular shape of the first fixing part 82. It is particularly suitable for narrow door leaves.

[0086] The triggering module corresponds in essential parts to the first embodiment example described above. The description of the first embodiment example therefore also applies to this triggering module, unless otherwise described below.

[0087] The triggering module according to this third embodiment has the pivot arm 80, the roller or wheel 81 and the first fixing part 82. The pivot arm 80 has a beam, which is preferably shorter than in the first embodiment. The connecting pin 84 with the slotted free end 840 is arranged at one end face end of the beam. Preferably, it is screwed in. As in the examples already described, the connecting pin 84 serves to connect to the actuating part 5 of the drop-down seal.

[0088] The opposite end of the beam has the recess 805 for receiving the first fixing part 82. The pivot arm 80 is pivotable about the pivot axis 89 relative to the first fixing part 82.

[0089] A receptacle for the wheel 81 is arranged in the beam of the pivot arm 80, preferably the receptacle 800, as already described in the examples mentioned above. Preferably, the receptacle is formed on a side wall of the beam of the pivot arm 80 in the form of a protruding lug. The wheel 81 is rotatable about the first axis of rotation 880. Instead of a lug, other designs of the pivot arm can also be formed as a receptacle for the wheel 81.

[0090] The first fixing part 82 is an angled element with two legs. The angle between them is preferably 90?. The first leg has the fourth through-opening 820 and can be arranged in the recess 805 and pivotably fixed. The fourth through-opening is not visible in FIGS. 18 and 19. The second leg has the fastening opening 821 for receiving the first screw 83.

[0091] The first fixing part 82 extends parallel or approximately parallel to the pivot arm 80. It is screwed to a front end face of the door leaf by means of the first screw 83. The type of assembly is shown in FIG. 6.

[0092] In the applications illustrated in the figures, the wheel 81 rolls on the door case, or on the door frame. As an alternative, a run-up ramp, an outwardly or inwardly curved surface, or a differently designed contact surface, which is made to interact with the wheel 81 and thus with the triggering module 8 when the door leaf T is being closed, may be attached to the door case or the door frame.

[0093] The seal device according to the invention enables optimum use in pivoting doors.
