Definitions

• the invention relates to a seal, in particular for a smoke protection sliding door.
• Smoke protection sliding doors are used for smoke-tight closure of rooms and must therefore also be provided with effective seals in the area of their closing edges, which reliably prevent the passage of smoke in the event of a fire.
• the elastic deformability of the seals can be influenced by their configuration as a closed or open profile. It is also possible to influence the fact that at one end edge, for. B. on the movable wing, an open profile and on the other end edge, for. B. on a second movable wing or on a frame, a closed profile is used. So two different profiles had to be used. If you also wanted to vary the elastic deformability along the front edge, previously you had to arrange different types of profiles one behind the other on the front edge. This is not only cumbersome, but also requires a lot of time to individually adjust the elastic deformability when it comes to sealing the smoke protection sliding door in a smoke-tight manner over its entire height. Additional storage with different profiles is also required.
• the free ends of the sealing lips end near the axis of symmetry of the sealing element. This simplifies handling during installation and ensures a good sealing effect.
• the web preferably has a thickened central section between the predetermined breaking points. In this way, the elastic deformability of the web is positively supported. This can be further improved if the web is curved on the outward-facing side and the thickened central section is formed by an inward-facing bulge.
• the sealing element can be produced and handled particularly easily if, according to an advantageous development, the sealing lips are arranged on a common base.
• the invention provides that the base is held on the movable wing, preferably replaceably, via a positive connection.
• the free ends of the sealing lips preferably point towards the base. This contributes to an improvement in the sealing effect.
• the first sealing element cooperates with a second sealing element, which either on a fixed part, for. B. a frame, or is arranged on a second movable wing.
• the sealing effect is particularly improved by the interaction of two sealing elements.
• the first and the second sealing element are of identical design. This reduces the manufacturing and storage costs and contributes to problem-free handling of the seal according to the invention.
• the first and the second sealing element can be designed differently. Depending on the design, this can be advantageous to e.g. B. to achieve certain effects.
• the second sealing element can also be designed as a closed sealing element and have an arc-shaped sealing bead, the apex of which lies in the axis of symmetry. This also ensures a secure sealing effect and has the additional advantage that the elastic deformability can be varied further.

• the second movable wing 2 it can also be a fixed part, such as. B. act a door frame or the like.
• An elastic sealing element 3, 4 with an open profile is arranged on the front faces of the two wings 1, 2 in the closing direction.
• the sealing element 3, 4 has a base 5 with which it is held in a form-fitting manner on the respective wing 1, 2.
• an essentially C-shaped groove is shown, in which the base is exchangeably received.
• any other configurations are possible as long as they ensure that the sealing element 3, 4 can be exchangeably held.
• both sealing elements 3, 4 are of identical design. They have free sealing lips 6 starting from the ends of the base 5, which are curved in an arc shape, run towards one another and have a free end 7.
• the free ends 7 are spaced apart from one another by an intermediate space 9 and are inclined inwards towards the base 5. They end in the vicinity of the axis of symmetry 8 of the sealing element 3, 4.
• the free ends 7 of the sealing lips 6 are at a distance from the base 5 in the unloaded state.
• the sealing element 3 also has a web 10 which bridges the intermediate space 9.
• the web 10 is connected to the sealing lips 6 via predetermined breaking points 11.
• the formation of the predetermined breaking points 11 can, for. B. in the form of a thin section (as shown) or as a perforated line or in any other suitable manner.
• the web 10 has a thickened central section 12 between the predetermined breaking points 11, which is arched on the outward-facing side.
• the thickened central section 12 is formed by an inward-facing bulge, the greatest extent of which lies in the region of the axis of symmetry 8.
• FIGS. 2 and 3 show the central section of the sealing element 3 in an enlarged view. 2 shows the sealing element 3 with the web 10 present, while FIG. 3 shows the sealing element 3 with the web 10 removed.
• the web 10 can be removed by simply tearing it out, cutting it off or the like.
• FIG. 4 shows a second embodiment of the seal according to the invention, in which the two sealing elements 3, 4 have different shapes.
• One sealing element 3 corresponds to the configuration for the sealing element 3 described in connection with FIGS. 1 to 3 (the web 10 being removed here), while the other sealing element 4 is designed as a sealing element with a closed profile and has an arc-shaped sealing bead 11 , whose apex lies in the axis of symmetry 8.
• the sealing bead 11 encloses a cavity 13.
