DESCRIPTION OF THE INVENTION

[0058] 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 recess for receiving a seal device S is formed in the bottom end face of the door leaf T. In other embodiments, a recess 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 recess, the seal device S can also be fastened for example on the door leaf T.

[0059] Depending on the embodiment, the wall W itself forms the frame for the door leaf T, or a case arranged in the wall opening is present.

[0060] FIGS. 2 to 5 illustrate a first embodiment of the seal device according to the invention.

[0061] 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. The embodiments illustrated in the rest of the figures are also preferably arranged on or in the door leaf T in this way and preferably have the drop-down seal described below.

[0062] The seal device S has a drop-down seal, which is arranged in a recess A in the door leaf T. The drop-down seal is preferably a seal of the known type. The drop-down seal illustrated in FIGS. 4, 6 and 13 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. The lowering mechanism has a different design depending on the embodiment. It preferably has leaf springs and a longitudinally extending slide 8. This lowering mechanism is known in the prior art. Alternative lowering mechanisms can likewise be used.

[0063] The sealing strip has a carrier profile rail and a sealing profile 3 integrally formed or fastened thereon. The carrier profile rail cannot be seen in the figures. It is arranged inside the housing profile rail 1. 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.

[0064] An actuating part 2 protrudes beyond the end face of the carrier profile rail and/or the housing profile rail 1. The actuating part 2 is preferably in the form of a bolt or a rod. Depending on the embodiment, it is hollow or solid. It preferably has an external or an internal thread for connection to the slide. In this example, as can be seen in FIG. 9, there is an internal thread in which the slide 8 of the lowering mechanism is screwed.

[0065] The actuating part 2 acts on the lowering mechanism via the connection to the slide 8. If it is pressed in towards the housing profile rail 1, the lowering mechanism lowers the sealing strip, preferably counter to the spring force. If the pressure on the actuating part 2 is stopped, i.e. the actuating part 2 is rereleased, the sealing strip is raised again owing to the restoring force of the springs.

[0066] The sealing profile 3 preferably protrudes beyond the carrier profile rail and preferably also from the housing profile rail 1. 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. It preferably sealingly abuts the vertical door frame, or the case, when the door is closed and thus forms not only a seal with respect to the floor, but also an end-side seal.

[0067] 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, as can be seen in FIGS. 2 and 3. The triggering module forms the end side of the seal device and is preferably likewise arranged in the recess A in the door leaf T.

[0069] As can be clearly seen in FIG. 4, the triggering module has a guide element, preferably in the form of a mounting sleeve 4, a coupling part 5 and a rotation element, in this case a ball 6. The mounting sleeve 4 has a hollow-cylindrical main body 40, which forms a through-opening 42. A longitudinally protruding lug 41 is integrally formed on a first end face of the main body 40 and a flange, which forms a preferably plane-parallel wall 43, is present on the oppositely situated end face. A fastening opening 44 for a fastening element, preferably for a screw or a nail, is present in the wall 43.

[0070] In this embodiment, the coupling part 5 likewise has a hollow-cylindrical main body 50. Its outside diameter is dimensioned such that it can be longitudinally displaceably held in the through-opening 42 in the mounting sleeve 4.

[0071] The main body 50 of the coupling part 5 has a receiving opening 51. The receiving opening 51 is in the form of a bearing for a ball 6. The design of such ball bearings are known.

[0072] The main body 50 of the coupling part 5 has, at its end facing towards the drop-down seal, a flattened portion 52 in the circumference. The flattened portion 52 serves as a cutout for the lug 41.

[0073] The coupling part 5 is pushed into the mounting sleeve 4 together with the rotatably mounted ball 6. It can be fastened on the end face of the door leaf T by means of a screw, which is not illustrated here. By virtue of the protruding lug 41, the drop-down seal can be fastened on the door leaf at the same time. For this, the lug 41 is pushed into the groove 10 formed underneath a bar of the housing profile rail 1.

[0074] In other embodiments, the housing profile rail 1 and the triggering module are fastened on the door leaf separately. In further embodiments, the triggering module, in particular the guide element, is integrally formed or detachably or non-detachably fastened on the housing rail 1.

[0075] FIG. 5 illustrates the assembled state, mounted on the door leaf F, of the triggering module. The drop-down seal is not illustrated in this figure, although it is usually fastened together with the triggering module.

[0076] In this example, the actuating part 2 is not connected to the coupling part 5. It makes contact only with the coupling part 5. This happens no later than when the ball 6 rolls on the door frame, or the case, when the door is being closed and the coupling part 5 is pressed into the mounting sleeve 4, and thus also pushes the actuating part 2 into the housing rail 1. As a result, the lowering mechanism is activated counter to a spring force and the sealing strip with the sealing profile 3 is lowered. When the door is being opened, there is no pressure on the ball 6. The sealing strip is then raised again thanks to the spring force of the return springs and the actuating part 2 is displaced in the opposite direction, i.e. in the direction of the end face of the housing rail 1. As a result, it pushes the coupling part 5 and the ball 6 outwards again.

[0077] In other embodiments, the actuating part 2 according to FIG. 4 is connected to the coupling part 5, either fixedly or flexibly, for example via a spring. This fixed or flexible connection is preferably detachable.

[0078] FIGS. 6 to 12 illustrate a second embodiment of the seal device according to the invention. The drop-down seal with the housing profile rail 1, the sealing strip with the sealing profile 3, the lowering mechanism, which is not illustrated, and the actuating part 2 have already been described on the basis of the first exemplary embodiment. The description above also applies here.

[0079] The mounting sleeve 4 has the same design as in the first exemplary embodiment, except for the fact that the cross section of the through-opening 42 is not round, but elongate. The cross section preferably has the shape of a horizontal rectangle with rounded short sides.

[0080] The coupling part 5 has a cuboidal main body 50 with a slot 54, which forms a receiving fork for receiving the rotation element. The rest of the main body 50 preferably has a solid form in this example. That is to say, its end face that faces towards the drop-down seal preferably has a closed form.

[0081] The rotation element is a wheel or a roller 7 in this example. The roller 7 has a preferably central through-opening 70. A respective through-opening 53, which are in line with one another, is formed in the two arms of the main body in the region of the slot 54. The roller 7 can be rotatably mounted in the receiving fork by means of a bolt 55 guided through the two through-holes 53. In this arrangement, the axis of rotation of the roller 7 extends in the bolt 55 and thus parallel to the pivot axis D of the door leaf T, or parallel to the direction of movement of the sealing strip.

[0082] In another embodiment, which is not illustrated here, the longitudinal direction of the through-opening 42 in the mounting sleeve 4 extends parallel to the direction of movement of the sealing strip. In this case, the axis of rotation of the roller likewise extends parallel to the pivot axis D of the door leaf T, but perpendicularly in relation to the direction of movement of the sealing strip.

[0083] FIG. 7 illustrates the triggering module according to the invention together with the drop-down seal in a recess A of a pivotable door leaf. The fastening screw for fastening, which is screwed in through the fastening opening 44, is not illustrated. In this embodiment, the roller 7 protrudes laterally beyond the coupling part 5 and in its diagonals is not received in the through-opening 42. In other embodiments, however, the receiving opening 42 has a stepped form, with the result that the roller 7 can be received deeper in the through-opening 42 in the mounting sleeve 4 and thus deeper in the recess A in the door leaf T. A stepped design is shown, for example, in the variants according to FIGS. 13 and 17.

[0084] In FIG. 8, the shape of the recess A can be clearly seen. It is composed of a known groove with plane-parallel side walls for receiving the housing profile rail 1 of the drop-down seal and a widened portion formed on the upper end of the groove. The widened portion preferably corresponds to the outer shape of the main body 40 of the mounting sleeve 4. The height of the recess preferably corresponds approximately to the height of the housing profile rail 1, i.e. it also preferably projects into the widened portion.

[0085] In FIGS. 9 to 11, the assembly of the seal device according to the invention can be clearly seen. In FIG. 9, it can be seen that the slide 8 is connected to the actuating part 2. It can also be seen that the free end of the actuating part 2 abuts the end face of the main body 50 of the coupling part 5. As has already been described on the basis of the first example, there is preferably only contact, but no fixed or flexible connection, between the actuating part 2 and the coupling part 5. The coupling part 5 is displaceable relative to the main body 40 of the mounting sleeve, being displaceably mounted therein.

[0086] In FIG. 12, the sealing profile 3 is already partially kneaded out, with the result that it extends at least as far as the wall 43. Depending on the lowering mechanism, this is already sufficient for an end-side seal in the lowered state. A reason for this is that, as it lowers, the sealing strip is usually also displaced in the longitudinal direction, specifically towards the trigger side.

[0087] FIGS. 13 to 15 illustrate a further exemplary embodiment. This example has substantially the same design as the second exemplary embodiment. The differences lie in the design both of the coupling part 5 and the through-opening 42 in the mounting sleeve 4. These two differences may also be brought about independently of one another. That is to say, the second exemplary embodiment according to FIGS. 6 to 12 can also be further developed with only one of these differences.

[0088] In this example, the coupling part 5 is formed in one piece with the actuating part 2. In a variant, the actuating part 2 is fixedly connected to the coupling part 5. This fixed connection, depending on the embodiment, is detachable or is not detachable nondestructively.

[0089] The through-opening 42 in the mounting sleeve 4 has a cruciform design, with the result that the coupling part 5 can be received in two different alignments. In the first alignment, the bolt 55 and thus the axis of rotation of the roller 7 extends parallel to the direction of movement of the sealing strip with the sealing profile 3. In the second alignment, the bolt and the axis of rotation of the roller extend perpendicularly in relation to the direction of movement of the sealing strip. What is meant by direction of movement is the main movement of the sealing strip perpendicularly in relation to the longitudinal direction of the housing profile rail or the sealing strip.

[0090] The through-opening 42 in the mounting sleeve 4 has a stepped form, and then the diameter of the roller 7 is received in the through-opening 42 in the two alignments. This can be clearly seen in FIG. 14.

[0091] FIG. 15 illustrates the installation situation in a door leaf, in this case a rebated door. The drop-down seal, which is usually fastened together with the triggering module, is not illustrated. Comparing FIGS. 7 and 15 shows that, in the example according to FIG. 15, the roller 7 protrudes beyond the wall 43 of the mounting sleeve 4 and thus the end face of the door leaf to a lesser extent.

[0092] FIGS. 16 and 17 illustrate a fourth exemplary embodiment. The difference in relation to the third exemplary embodiment according to FIGS. 13 to 15 is that that coupling part 5 has a different design. It is not connected to the actuating part 2. The main body 50 has a correspondingly longer design. Its length is similar to or the same as that of the second exemplary embodiment according to FIGS. 6 to 12.

[0093] The main body 50 preferably has grooves 56, which extend from the openings, i.e. the through-openings 53 and the slot 54, to the end facing towards the actuating part 2. The grooves 56 each have an elevation at the end opposite the through openings 53 and are used for latching the main body 50 into the mounting sleeve 4. The mounting sleeve 4 preferably has corresponding latching-in elements.

[0094] Door leaves T usually have grooves N that have already been made in the factory with parallel side walls. The height and width of the grooves are dimensioned such that they can receive the housing rails of the drop-down seals. The dimensions for this are usually standardized. In order now to be able to easily introduce the additional widened portion for receiving the mounting sleeve 4 into already manufactured door leaves, a drilling jig 9 can be used. A preferred exemplary embodiment is illustrated in FIGS. 18 and 19.

[0095] The drilling jig according to FIGS. 18 and 19 has a substantially cuboidal main body 90, on which a foot 91 which preferably protrudes on one side is formed. A sliding block 93, the width of which corresponds to one of the known dimensions of the prefabricated door grooves N, is integrally formed on the upper surface of the foot 91 and that side of the main body 90 that faces towards this upper surface.

[0096] Above the sliding block 93 and preferably adjoining it, the main body 90 has a drill hole 92, the inside diameter of which corresponds to the desired dimension in the widened portion to be introduced into the groove N. The drill hole 92 ends exactly at or only slightly above the standard height of the prefabricated groove N.

[0097] Above the drill hole 92, a continuous fastening opening 94 is preferably present in the main body 90.

[0098] The drilling jig is formed in one piece. It is preferably made from metal. However, it may also be made from other materials, such as wood or a plastic.

[0099] FIGS. 20 to 22 now show how the drilling jig can be used. Its sliding block 93 is pushed into the prefabricated groove N in the door leaf T. In the process, the foot 91 is pushed under the door leaf T. If it hangs out of the door leaf T, as is usually the case, the foot 91 serves as a stop. The door leaf T is processed horizontally rather than upright, as illustrated.

[0100] Then the screw 95, which is subsequently also used to fasten the mounting sleeve 4, can be screwed into the drilling jig 9. As a result, for the one part, the drilling jig 9 is fixed to the door leaf T. For the other part, the fastening hole for the mounting sleeve 4 is already made in the door leaf T, without further work steps being needed for this.

[0101] The drill hole 92 in the drilling rig 9 mounted according to FIG. 21 then serves as a specification for drilling a hole in the door leaf T. The result is illustrated in FIG. 22. It was therefore possible to create the designed recess A for mounting the seal device according to the invention in few work steps. The small hole for introducing the screw 95 when the mounting sleeve 4 is being fastened on the door leaf is not illustrated in FIG. 22, but it is present.

[0102] The seal device according to the invention makes it possible to use a triggering module optimally in force terms and can also be used in pivot doors, in particular in rebated doors.
