Description

[0001] The present invention relates to a seal for sliding doors and sliding gates, with at least one release rod and with a release, wherein the seal a. a coupling element, b. a housing, c. a sealing strip and d. at least one movement mechanism, e. wherein the trigger, the trigger rod and the coupling element are connected to one another, f. wherein the movement mechanism connects the housing and the sealing strip so that it can be moved relative to one another and the movement mechanism has movement deflection means in order to convert a movement of the coupling elements into a movement of the sealing strip, g. wherein by means of the coupling element a force introduced into the trigger rod via the trigger can be transmitted to the movement deflection means of the movement mechanism in order to move the sealing strip, and h. the movement mechanism is a scissors mechanism and the movement deflection means are formed by scissor elements.

[0002] Document EP 3 599 335 A1 discloses such a sealing arrangement for a sliding gate (called a seal there, in contrast to the terminology used in the present application). It is composed of individual seals (called segments there, in contrast to the terminology used in the present application) that can be arranged side by side on a gate leaf of a sliding gate. The number of segments determines the length of the seal, which can thus be adjusted to the width of the gate. This seal can only be actuated by pressing the trigger and has a scissor mechanism as the actuation mechanism.

[0003] A seal for a sliding door is known from document EP 2 634 350 B1. This document discloses two exemplary embodiments. One of the exemplary embodiments has a leaf spring mechanism as the movement mechanism. For the movement mechanism of the second exemplary embodiment, the document does not specify the design of the movement mechanism. A leaf spring mechanism, as used in the seal known from document EP 2 634 350 B1, has the disadvantage that, due to the design of the movement mechanism, when the sealing strip is moved, an offset relative to its rest position occurs. This offset is greater the greater the stroke of the sealing strip, which is greater the larger the gap to be closed by the seal.

[0004] However, one advantage of the seal known from document EP 2 634 350 B1 is that the seal can be converted into a pressure-actuated seal with just a few changes, which is also described in the document, or that many of the components used can also be used for a pressure-actuated seal.

[0005] From document EP 3 165 703 B1 a seal with a leaf spring mechanism is known which can be actuated by both tension and pressure.

[0006] The gap is often larger for wide or sliding doors than for narrow doors. This is because, due to uneven surfaces, larger gaps are often deliberately accepted or even deliberately chosen to prevent the door or gate from hitting the uneven surface.

[0007] The object of the invention was to create, starting from the seal mentioned at the beginning, a seal that can be actuated by pulling and that has little or no offset, even if the gap to be sealed is very large.

[0008] This object is achieved according to the invention in that the trigger is provided in the region of a first end of the housing of the seal and projects laterally beyond the housing and in that the coupling element is arranged in the region of a second end of the housing opposite the first end, in that the movement of the sealing strip can be actuated by pulling on the trigger, in that the trigger rod has a thread at both ends and in that one of the two threads of the trigger rod is connected to a complementary thread of the trigger and the other of the two threads of the trigger rod is connected to a complementary thread of the coupling element and in that the trigger has a threaded hole into which one end of the trigger rod is screwed.

[0009] This seal can be used for both a sliding gate and a sliding door to seal gaps at the bottom or top of the sliding gate or sliding door.

[0010] The threaded connections on the trigger rod can transmit tensile forces, which are then transferred from the trigger via the trigger rod to the coupling element during a pull-triggered release. Other connections that can transmit tensile forces can also be selected. One advantage of threaded connections over other connections is that they are adjustable. This allows the position of the trigger, the trigger rod, and the coupling element to be adjusted. This can be useful not only for adjusting the seal's stroke but also for compensating for manufacturing tolerances.

[0011] In particular, it is possible that the coupling element has a threaded hole into which the other end of the trigger rod is screwed.

[0012] The housing may have a first channel in which the trigger rod is slidably arranged.

[0013] Furthermore, the housing can have a second channel running parallel to the first channel, in which the one sealing strip and the at least one movement mechanism are arranged. A slotted hole through which the coupling element passes can be provided in a partition wall between the first and second channels.

[0014] The coupling element can have a connecting structure on a side opposite the connection to the trigger rod, for example, a blind hole with or without an internal thread, into which another trigger rod can be inserted, which is connected to another trigger that can be actuated by pressure. Thus, with few modifications, the seal according to the invention can be converted into a pressure-actuated seal, which then bears great similarity to a seal of the sealing arrangement known from document EP 3 599 335 A1.

[0015] If the gate has a large width, a sealing arrangement according to the invention according to claim 7 can be used.

[0016] This is designed according to the invention in such a way that it has a seal according to the invention as the first seal and at least one further seal, wherein the further seal a. a release rod, b. a coupling element, c. a housing, d. a sealing strip and e. at least one movement mechanism.

[0017] The coupling element of the first seal, the trigger rod of the further seal and the coupling element of the further seal are connected to one another, wherein the movement mechanism of the further seal connects the housing of the further seal and the sealing strip of the further seal so that it can be moved relative to one another, and the movement mechanism of the further seal has movement deflection means in order to convert a movement of the coupling element of the further seal into a movement of the sealing strip of the further seal, wherein by means of the coupling element of the further seal a force introduced into the trigger rod of the further seal by the coupling element of the first seal can be transmitted to the movement deflection means of the further seal of the movement mechanism of the further seal in order to move the sealing strip of the further seal.

[0018] According to the invention, the trigger rod of the additional seal can project beyond a first end of the housing of the additional seal. The coupling element of the additional seal can be arranged in the region of a second end of the housing of the additional seal, opposite the first end.

[0019] The trigger rod of the additional seal can have threads at both ends. One of the two threads of the trigger rod of the additional seal can be connected to a complementary thread of the coupling element of the first seal, and the other of the two threads of the trigger rod of the additional seal can be connected to a complementary thread of the coupling element of the additional seal. The coupling element of the first seal can have a threaded hole into which one end of the trigger rod of the additional seal is screwed. In this way, a force introduced into the trigger can be introduced into the movement mechanism of the additional seal via the trigger rod of the first seal, the coupling element of the first seal, the trigger rod of the additional seal, and the coupling element of the additional seal.

[0020] The movement mechanism of the further seal can be a scissor mechanism.

[0021] The first seal and the second seal can be identical except for the trigger, which is missing from the second seal. Instead, the trigger rod of the second seal is connected to the coupling element of the first seal.

[0022] Further features and advantages of an embodiment of the invention are described below with reference to the drawings. Fig. 1 a perspective view of the seal according to the invention, Fig. 2 a section of Fig. 1 , Fig. 3 a view of the seal from the front, Fig. 4 a view as in Fig. 3 , but without housing and without sealing strip, Fig. 5 a section of Fig. 3 , Fig. 6a section as in Fig. 5, but without module housing Fig. 7a view of the seal from the trigger side, Fig. 8a view of the seal from the side opposite the trigger and Fig. 9a section of a longitudinal section through the seal according to lines IX-IX in the Figure 7 .

[0023] It is not necessary for a device according to the invention to have all of the features described below. It is also possible for a device according to the invention to have only individual features of the exemplary embodiment described below.

[0024] A seal according to the invention comprises, among other things, a housing 1, a trigger rod 16 and a trigger 3.

[0025] The housing 1 has a substantially constant cross-sectional profile along its length. In the example shown, the housing is essentially in the shape of an inverted U with two legs 11 and a connecting web 12 that connects the two legs 11 to each other. On an inner side of the web 12 of the housing 1, two further legs 13 are provided, which are connected to each other by a further web 14 and thus form a first channel. Free ends of the legs 13 are slightly undercut on mutually facing sides, so that the facing sides form a groove 131.

[0026] Angled legs 15 are provided on the outside of the web 12. These can be inserted into a profile at the lower end of a door or gate leaf for attachment there. Other types of attachment are familiar to those skilled in the art, particularly from published patent applications. Depending on the type of attachment, the housing can be modified to provide, for example, channels, webs, screw holes, or other features useful for attaching the seal to a door or gate.

[0027] Each seal also has a sealing strip 2. In the example, the sealing strip 2 is made of two parts. However, it could be made of one part or have more than two parts. In principle, any sealing strip known from the prior art can be used. In the example, the sealing strip comprises a rigid holding profile 21, preferably made of aluminum, and an elastomeric sealing profile 22. In the example, both have a constant cross-sectional profile along their length. In the example, the holding profile 21, like the sealing profile, is essentially U-shaped in cross-section. The holding profile 21 and the sealing profile 22 each have a connecting web 211, 221 and two legs 212, 222 each, which are connected to one another via the connecting web 211, 221.

[0028] The sealing profile 22 is fastened via locking webs 223 in locking channels 213 of the holding profile 21.

[0029] On the inside of the legs 212 of the holding profile 21, two webs 214 are provided, which together with the connecting web 211 form channels, the purpose of which will be explained in more detail below.

[0030] The seal has a coupling element 7, which is slidably inserted in an area at the end of the first channel of the housing 1 remote from the trigger. On a side facing the trigger 3, the coupling element has a blind hole with an internal thread, into which one end of the trigger rod 16 is inserted, which is provided with an external thread 161. The rod 16 also has an external thread at the opposite end, which is screwed into a threaded hole in the trigger 3. The screw-in depth can determine the projection of the trigger beyond the housing 1. The rod extends from the coupling element 7 across almost the entire width of the seal to the trigger-side end of the housing 1.

[0031] In alignment with the blind hole on the side facing away from the trigger, the coupling element 7 has a further blind hole with an internal thread.

[0032] If several seals are arranged next to one another (not shown), one end of a trigger rod of the adjacent seal is screwed into the blind hole of the coupling element 7 remote from the trigger, and its other end, which is also provided with an external thread, is screwed into the coupling element of the adjacent seal.

[0033] The coupling element 7 of each seal has a projecting part 71. This projecting part 71 has a connecting structure that connects the coupling element 7 to the mechanism of the segment. The projecting part 71 of the coupling element can protrude into a second channel of the housing 1 of the segment, in which the mechanism for moving the sealing strip 2 of the seal is arranged. To allow the projecting part 71 to protrude from the first channel between the web 12, the legs 13, and the web 14 into the second channel, the web 14 has a slot 10 away from the trigger.

[0034] In the housing 1 of the seal, three modules Ma, Mb, Mc are arranged, which in the exemplary embodiment comprise all parts that serve to ensure safe movement of the sealing strip 2 relative to the housing 1.

[0035] The parts of the seal belonging to the modules Ma, Mb, Mc are partly identical in the modules. These parts can then be used in the modules Ma, Mb, Mc for the same functions as the modules Ma, Mb, Mc. The modules Ma, Mb, Mc also partly have special functions that require special parts. Functions that the first module has in the example can be performed by the second or third module in another embodiment of a seal according to the invention, and vice versa. It is therefore within the scope of the invention to modify the parts of the modules Ma, Mb, Mc so that they can take on fewer, different or additional functions if necessary.

[0036] Identical or functionally similar parts of modules Ma, Mb, and Mc have the same reference numbers and are distinguished by the suffixed letters a, b, and c, where a stands for parts of the first module Ma, b for parts of the second module Mb, and c for parts of the third module Mc. When discussing details of parts of modules Ma, Mb, and Mc, these are referred to without suffixed letters if they are found in parts of all modules Ma, Mb, and Mc.

[0037] In the example, all modules Ma, Mb, Mc of the seal 1 have the function of connecting the sealing strip 2 and the housing 1 and, when the seal is triggered by pressing a trigger 3, converting the movement of the trigger 3 and the trigger rod 16 into a movement of the sealing strip 2 relative to the housing 1. For this purpose, each module Ma, Mb, Mc has a scissor mechanism Sa, Sb, Sc. In order to protect this scissor mechanism Sa, Sb, Sc of each module Ma, Mb, Mc in the event of an overload, each module Ma, Mb, Mc also has an overload mechanism Ua, Ub, Uc. The modules are described in detail in document EP 3 284 899 A1. Reference is made to this description.

[0038] The modules Ma, Mb, Mc can be placed in a housing 1 at the discretion of a specialist. It is possible to design a seal so that it has only one module.

[0039] Each module Ma, Mb, Mc comprises a module housing 4. This has a substantially uniform cross-sectional profile in the shape of an inverted U. It has a connecting web 41 that connects two legs 42 of the module housing 4. Webs 43 are attached to the inner sides of the legs 42. These, together with the connecting web 41, form channels whose function will be explained below.

[0040] The connecting web 41 projects beyond the outer sides of the legs 42. These projecting ends of the connecting web 41 are designed such that they form a fit with the grooves 131 on the mutually facing sides of the legs 13 of the housing 1. In particular, a clearance fit with a slight clearance can form during the fit. The module housing 4 is pushed with the projecting ends of the connecting web 41 into the grooves 131 on the mutually facing sides of the legs 13 of the housing 1 and is thus fixed in the housing 1 at least in a form-fitting manner. Complete fixing can be achieved, for example, by at least selectively deforming the legs 13 of the housing 1 inwards, i.e. against the projecting ends of the connecting web 41. Parts of the legs 13 can thus be pressed against the ends, so that a force-fitting connection is established.

[0041] In an area of ​​the module housing 4 of each module near the trigger, two opposing holes are provided in the legs 42, directly adjacent to the webs 43. Pins 51 of a short scissor element 5 are rotatably arranged in these holes. These pins 51 also bear against the underside of the webs 43, thereby supporting the pins 51 in the event of a load toward the webs 43 and protecting them from shearing off.

[0042] The short scissor element 5 of each module is described in more detail in the document EP 3 284 899 A1 with reference to Figures 11 to 14c and in Fig. 6 and 9 of this document. It is essentially H-shaped. It has a connecting bar from which two arms and two legs extend. Attached to the ends of the arms, which are slightly shorter than the legs, are the outwardly projecting pins 51, whose function has already been explained.

[0043] Two inwardly projecting pins are provided on the legs, which serve to connect to a long scissor element 6.

[0044] The long scissor element 6 of each module is also described in more detail in the document EP 3 284 899 A1 with reference to Figures 11 to 14c and in Fig. 6 and 9 of this document. It can be divided into two sections, namely a first section that forms a frame, and a second section that forms a rod. The two sections are connected to each other. In the area of ​​the connection, the second section of the long scissor element has two outwardly opening blind holes. The inwardly projecting pins of the short scissor element are inserted into these blind holes. This pivotally connects the long and short scissor elements.

[0045] The free end of the first section, or rather the opening present in this first section, serves to guide and support the long scissor element 6, which will be explained in more detail below. This free end is movable relative to the module housing 4.

[0046] At the free end of the second section of the long scissor element, two outwardly projecting pins 61 are provided, which serve to connect the long scissor element 6 to the retaining profile 21 of the sealing strip. The pins 61 are movably guided and mounted in the channels formed by the webs 214 and the connecting web 211 of the retaining profile 21.

[0047] The second section of the long scissor element 6 has a width that is not greater than the distance between the legs of the short scissor element 5. This makes it possible for the second section to be immersed between the legs, for example when the seal is not triggered.

[0048] The long scissor element 6 and the short scissor element 5 together form the scissor mechanism S of each module M.

[0049] Each module M has a sliding part 8, which is described in more detail in document EP 3 284 899 A1 with reference to Figures 15b and 15d. The sliding parts 8 of the first module Mb and the second module Mc are identical. The sliding part of the third module Ma differs. This will be discussed in more detail. The sliding part 8 has a flat, rod-like section 84 that extends over the entire length of the sliding part 8. This flat, rod-like section 84 has approximately the shape of a T. Two projecting edges of the rod-like section 84 project into the channels formed by the webs 43 and the connecting web 41 of the module housing 4. The edges, and thus the entire sliding part 8, are guided displaceably in the channels.

[0050] Three different structures 81, 82, 83 are provided on an underside of the rod-like section.

[0051] The structure 81 at an end of the sliding part 8 remote from the trigger serves as a first connecting structure, which is provided for connecting the sliding part 8 of the first module Ma to the coupling element 7 of the seal. The connecting structure 81 can be connected to the coupling element 7 by positive locking. In the second and third modules Mb, Mc, the structure serves to connect to a first and second connecting rod 9, respectively. For this purpose, the connecting structure 81 has a blind hole into which the connecting rod 9 is inserted. Furthermore, the structure 81 is part of the overload mechanism R of the first module Ma.

[0052] The structure 82 interacts with the scissor mechanism S of each module and is part of the overload mechanism of each module.

[0053] The structure 83 is a second connecting structure that serves to connect the sliding part 8 of the first module Ma and the second module Mb to a first and second connecting rod 9, respectively. For this purpose, it has a blind hole.

[0054] The structure 82 has an arm 821 extending toward the trigger-side end, which extends parallel to the rod-like portion 84 of the sliding part 8. This arm 821 passes through the opening in the first portion of the long scissor element 6 of the scissor mechanism S of each module. A free end of the first portion is thus supported and guided between the arm 821 and the rod-like portion 84 of the sliding part 8.

[0055] The free end 63 of the long scissor element 6 is held by a holder 9 for an overload spring 10 and the overload spring 10 in a position between the arm 821 and the rod-like section 84 of the sliding part 8. The overload spring 10 is a helical compression spring. The holder 9 for the overload spring is rod-like. It is described in more detail in document EP 3 284 899 A1 with reference to Figures 17 to 19b. It is also described in Fig. 6 and 9 of this document.

[0056] The return mechanism R serves to bring the seal from a triggered state back to a non-triggered state when the force triggering the seal is removed from the trigger 3. It is described in the document EP 3 284 899 A1 by virtue of which Figure 8 , 8a, 10 and 10a are described in more detail.
