The object of the invention is to provide a sealing device which enables a building closure device to be sealed in a particularly simple and reliable manner.

This task is solved by a sealing device and a building closure device with the features of claims 1 and 11. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the dependent patent claims.

The invention creates a sealing device for a building closure device for sealing a gap between a building closure element and a floor area of an opening to be closed by the building closure element. “Sealing” means, in particular, closing or filling the gap. “Gap” means in particular an intermediate space between the floor area and the building end element, in particular a narrow, elongated opening forming the intermediate space. The building closure device is, for example, a door or a gate, in particular a Sectional door, particularly preferably a garage door. Accordingly, the building closure element is in particular a door leaf or a gate leaf. The sealing device comprises a sealing threshold area which has at least one cavity. In other words, the sealing device can have a hollow chamber or a channel in the sealing threshold area. The cavity extends, in particular at least partially, i.e. completely or partially, in a main extension direction of the sealing threshold area. The main extension direction means in particular a longitudinal extension direction or length of the sealing device. In other words, the cavity can extend or expand at least partially over the length of the seal threshold area. The cavity is further limited by walls of the sealing threshold area. The walls can be designed as webs. In other words, webs can delimit or form the hollow chamber of the sealing threshold area. Furthermore, at least one wall on a side or surface facing the cavity has at least one groove, which extends in the main extension direction of the sealing threshold area. “Groove” means in particular a groove or a depression. In particular, the groove has a semicircular or rectangular or triangular shape or contour in cross section. Furthermore, the sealing device has a seal support area adjacent to the seal threshold area. In particular, the seal support area is designed as a base or a support on which something rests or on which something can be placed. In other words, the sealing device is divided into at least two elements or areas - the seal threshold area and the seal support area - which in particular have different functions of the sealing device. The sealing device is preferably designed in one piece or in one piece, i.e. formed from one part or piece.

By dividing the sealing device into different functional areas, the sealing device can fulfill several functions at the same time. The cavity in the sealing threshold area of the sealing device has the advantage that material can be saved in the manufacture of the sealing device, which means that Manufacturing process of the sealing device is particularly economical. Furthermore, the design of the cavity has the advantage that there is significantly less resistance when driving over the sealing device, for example with a motor vehicle. The groove on the side of the walls facing the cavity has the advantage that, for example, when driving over a motor vehicle, the sealing threshold area is defined and uniformly deformed.

An advantageous embodiment provides that two adjacent walls of the walls of the sealing threshold area are arranged relative to one another in such a way that the at least two walls form a bead. “Bulge” means in particular a thickening or elevation or a structure or a threshold. In particular, the at least two walls can be arranged next to one another in such a way that the sealing threshold area is triangular in cross section. In other words, the at least two walls of the sealing threshold area are arranged adjacent to one another in such a way that the sealing threshold area has a triangular contour or a triangular profile in cross section. In particular, the sealing threshold area can have a prism-like shape. Particularly preferably, due to the arrangement of the two walls, the cavity also has a triangular contour or shape. By forming a triangular contour in cross section, the at least two walls do not have to be specially designed, which means that the sealing threshold area is particularly easy to provide. Alternatively, the at least two walls can be arranged together in such a way that the sealing threshold area is rectangular or semicircular in cross section. Other contours in the cross section are also conceivable.

Advantageously, a first wall of the two adjacent walls is arranged inclined at a predetermined angle between 30° and 60°, preferably between 35° and 55°, particularly preferably 40° to a vertical direction of the seal threshold area. Additionally or alternatively, the first wall may be at a predetermined angle to a width direction or a transverse plane of the sealing device or the sealing threshold area be arranged inclined. The first wall can be arranged at the predetermined angle between 30° and 60°, preferably between 35° and 55°, inclined to the width direction. Particularly preferably, the first wall is arranged inclined at the predetermined angle of 50° to the width direction.

Preferably, a second wall of the two adjacent walls is arranged inclined at a predetermined angle between 40° and 60°, preferably between 50° and 55°, particularly preferably 52° to the vertical direction of the seal threshold area. Additionally or alternatively, the second wall can be arranged inclined at a predetermined, in particular second, angle to the width direction or the transverse plane of the sealing device or the sealing threshold region. The second wall can be arranged at the predetermined angle between 30° and 60° inclined to the width direction. Particularly preferably, the second wall is arranged inclined at the predetermined angle of 38° to the width direction. Furthermore, the two adjacent walls can limit or enclose an angle between 80° and 100°, in particular between 85° and 95°, particularly preferably 92°. Particularly preferably, the first wall of the two adjacent walls is arranged at a predetermined angle between 70° and 90°, particularly preferably 76°, inclined to the bottom region or a bottom surface of the sealing device.

According to an advantageous development, it is provided that the sealing threshold area on the first wall and the second wall of the two adjacent walls each has a groove on the side or surface facing the cavity. Particularly preferably, the respective groove is arranged centrally on the corresponding wall, i.e. the first wall and the second wall, and preferably extends in the main extension direction of the sealing threshold area. Additionally or alternatively, it can be provided that a vertex of the first wall and the second wall of the two adjacent walls has a groove on the side facing the cavity. “Vertex” means in particular the place or a point at which the first wall and the second wall adjoin or meet one another. The grooves allow the seal threshold area to have several bending zones. Through the appropriate arrangement of the grooves, a uniform and/or defined deformation can be achieved when a force acts on the seal threshold area, for example when a motor vehicle passes over the seal threshold area. As a result, the seal threshold area and thus the sealing device is particularly stable and can withstand external influences particularly reliably.

A further advantageous embodiment provides that the sealing device has a height of less than 20 mm, particularly preferably 17.5 mm. In particular, the height extends in a vertical direction of the sealing device, preferably perpendicular to the main extension direction of the sealing device. Particularly preferably, the seal threshold area of the sealing device is designed to be higher than the seal support area. The maximum height of the sealing device is preferably measured from a bottom surface of the sealing device, in particular perpendicular, to the apex of the sealing threshold area. By designing the height of the sealing device to be less than 20 mm, accessibility is ensured. Due to the flat design, the sealing device has little impact on a motor vehicle driving over the sealing device. Furthermore, the flat design of the sealing device can ensure that people do not get caught on the sealing device, in particular on the sealing threshold area, when crossing the sealing device. The sealing device is therefore designed to be particularly safe and reliable.

Advantageously, the seal support area comprises two slope regions, the first slope region adjoining the second wall of the sealing threshold region, the first slope region having a smaller slope than the second wall of the sealing threshold region, the second slope region adjoining the first slope region, the second slope region has a greater gradient than the first gradient range. In other words, the seal support area is divided into at least two areas - the first slope area and the second Slope range - divided into different slopes. By “slope” it is meant in particular that the respective slope areas have a sloping or descending or tilted or inclined or inclined or oblique plane or surface, which in particular defines the slope or the respective slope area. The corresponding plane can be arranged opposite the bottom surface of the sealing device. The respective slope areas preferably have a small shape. The seal support area is preferably formed in one piece or in one piece. In particular, the seal support area has the same length as the seal threshold area. In particular, the first pitch region and the second pitch region extend perpendicular to the main extension direction, that is to say in particular in a width direction of the sealing device. In particular, the first slope region is designed to be wider than the second slope region.

The walls of the sealing threshold area preferably have a wall thickness between 2 mm and 10 mm, in particular between 3 mm and 7 mm. Particularly preferably, the walls have a wall thickness of 3 mm at the apex, at which in particular the first wall and the second wall adjoin one another. This results in the advantage that the seal threshold area is designed to be particularly stable but still flexible, especially when the motor vehicle passes over the seal threshold area.

A further advantageous embodiment provides that the seal support area, in particular the first slope area of the seal support area, has a groove which extends in the main extension direction of the seal support area. In other words, the groove can extend at least partially, i.e. completely or partially, in the main extension direction. The groove is preferably arranged on a surface of the seal support area facing away from the bottom area or the bottom surface of the sealing device. In particular, the groove is arranged on the plane or surface of the seal support area which has the slope. The groove extends at least partially, i.e completely or partially, in the main direction of extension of the seal support area. The groove particularly preferably extends continuously along the seal support area. “Groove” means in particular a groove or a depression. The groove is used in particular for attaching screws and gives the user a certain stability, particularly during assembly, which can make assembly of the sealing device easier.

According to an advantageous development, it is provided that the sealing device, in particular the seal support area and the seal threshold area together, have a sealing base area, the sealing base area, which in particular faces the base area, having a plurality of recesses, the recesses being arranged at a predetermined distance from one another. In other words, the sealing device can have depressions or hollow chambers or channels on the underside, or the depressions or the hollow chambers can be formed on the underside. In particular, the depressions are arranged next to one another along the bottom region, in particular perpendicular to the main extension direction of the sealing device, that is to say in particular in the width direction. The depressions are preferably U-shaped, in particular in cross section. The depressions can also have a different shape, such as a trapezoidal or triangular shape or rectangular shape or contour, especially in cross section. In particular, the depressions together with the bottom area on which the sealing device is arranged each form a hollow chamber or a channel. Furthermore, a surface of the sealing base region facing the base region, in particular the base surface, can have a predetermined surface roughness, in particular grooves or notches. The depressions and/or the surface roughness result in the advantage that, particularly when assembling the sealing device, an adhesive material, for example adhesive, can be introduced in a particularly simple and reliable manner for fastening or mounting the sealing device to the floor area.

Preferably, the sealing base region can have an end face or end face which is arranged inclined to the width direction at a predetermined angle. In particular, the front side can be beveled. The end face of the sealing base area can be arranged at a predetermined angle between 90° and 120°, preferably between 100° and 110°, particularly preferably inclined by 104°, in particular away from the base area or towards the width direction. Additionally or alternatively, the sealing base area can have an end face or end face opposite the end face, which has a smaller gradient than the end face.

Advantageously, the sealing device is made of an elastic material, in particular rubber, particularly preferably ethylene-propylene-diene rubber, which can also be referred to as EPDM for short. By designing the sealing device from rubber, the sealing device is particularly robust. Ethylene-propylene-diene rubber also has the advantage that it is highly flexible in cold conditions and is also UV-resistant and durable.

The invention also includes a building closure device. The building closure device includes a building closure element. The building closure device is, for example, a door or a gate, in particular a sectional door, particularly preferably a garage door. Accordingly, the building closure element is in particular a door leaf or a gate leaf. The building closure device further comprises a sealing device of the type described above, which is designed to seal a gap between the building closure element and a floor area of an opening to be closed by the building closure element. In particular, the floor area is flat or flat. Since the sealing device is arranged on the floor area, it can also be referred to as a floor seal. The sealing device further has a sealing threshold area which has at least one cavity, the cavity extending in a main extension direction of the sealing threshold area. The cavity is delimited by walls of the sealing threshold area, with at least one wall on one The side or surface facing the cavity has at least one groove which extends in the main direction of extension of the sealing threshold area. Furthermore, the sealing device comprises a seal support area adjacent to the seal threshold area.

Advantageously, in a closed position of the building closure element, in which the building closure element closes the opening, the building closure element rests on the sealing support area. In particular, a support surface of the seal support area is larger than the area of the building closure element, which rests on the seal support area. The sealing device preferably extends over a length of the building closure element. Additionally or alternatively, in the closed position of the building closure element, in which the building closure element closes the opening, the sealing threshold area can adjoin a building closure element width side of the building closure element. In particular, in the closed position of the building closure element, the sealing threshold area lies against a surface or side, which in particular corresponds to a width side of the building closure element. This can ensure that liquid, for example water, present on the building closure element can be kept away from the building, for example the garage. Accordingly, the sealing threshold area can also be referred to as a storm threshold.

An advantageous embodiment provides that a width of the sealing device is adapted to a width of the frame feet of the building closure device. In other words, the sealing device, in particular the end faces of the sealing device, which rest on the frame feet, can be tailored to a profile width of the frame feet. The respective frame feet preferably have a contact area against which the sealing device rests at least partially with its end faces. “Frame foot” means a part or section or area of a frame spar arranged on the base area. According to an advantageous development, it is provided that the sealing device is fixed to the floor area by means of a fastening device, the fastening device comprising screws and/or an adhesive material, in particular an assembly sealing adhesive. Particularly preferably, the sealing profile, which is designed in particular as a rubber profile, is glued to the floor area with an assembly sealing adhesive. Additionally or alternatively, it can be provided that additional screw connections, for example using stainless steel screws, are used to fasten the sealing device to the floor area. The additional provision of screws to the assembly sealing adhesive has the advantage that the sealing device is fixed particularly reliably, since the assembly sealing adhesive can settle or shrink over time and this can lead to losses in fixation and thus stability. Alternatively, the sealing device can also be clipped onto the floor area.

The exemplary embodiments explained below are preferred embodiments of the invention. In the exemplary embodiments, the described components of the embodiments each represent individual features of the invention that can be viewed independently of one another, which also develop the invention independently of one another and are therefore to be viewed as part of the invention individually or in a combination other than that shown. Furthermore, the described embodiments can also be supplemented by further features of the invention that have already been described.

In the figures, identical or functionally identical elements are provided with the same reference numbers.

In the context of the Fig. 1 to Fig. 3 A sealing device 10 for a building closure device will be explained in more detail. The sealing device 10 is designed to seal a gap between a building closure element of a building closure device and a floor area of an opening to be closed by the building closure element. The building closure device can be, for example, a garage door. In particular, the garage door is designed as a sectional door. The building closure element can be a door leaf of the garage door. If the garage door is designed as a sectional door, the door leaf of the garage door can have several slats or panels, in particular hinged to one another. The number of panels and their width can vary depending on the width of the opening to be closed. The sealing device 10 is in particular adapted to the width of the opening to be closed, particularly preferably framed with a precise fit.

The sealing device 10 comprises a sealing threshold area 12, a seal support area 14 adjacent to the sealing threshold area 12 and a sealing base area 16. The sealing device 10 has different areas, but is designed in one piece or in one piece. How Fig. 1 and Fig. 2 To be taken, the sealing threshold area 12 has a cavity 18. The sealing threshold area 12 and the cavity 18 provided therein extend in a main extension direction of the sealing threshold area 12. The main extension direction corresponds in particular to a length of the sealing device 10. The length of the sealing device 10 is in particular adapted to the width of the opening. In relation to Fig. 1 and Fig. 2 the main extension direction extends vertically into the plane of the drawing.

The cavity 18 is delimited by at least two walls 20, 22 of the sealing threshold area 12. In particular, the cavity 18, which can also be referred to as a hollow chamber or channel, is through at least two walls 20, 22 are surrounded or formed. A part or section of the sealing base region 16 of the sealing device 10 preferably forms a further wall 24 of the sealing threshold region 12. In particular, the cavity 18 is delimited or bordered by three adjacent walls 20, 22, 24.

Furthermore, the sealing threshold area 12 has a first groove 26 on one of the first wall 20 of the two adjacent walls 20, 22 on a surface or side of the first wall 20 facing the cavity 18. Furthermore, the sealing threshold area 12 also has a second groove 28 on a second wall 22 of the two adjacent walls 20, 22 on a surface or side of the second wall facing the cavity 18. The first groove 26 and the second groove 28 are preferably arranged centrally on the surface of the respective wall 20, 22 facing the cavity 18 and extend in the main direction of extension of the sealing threshold area 12. Finally, the sealing threshold area 12 has a vertex 30 at which the first Wall 20 and the second wall 22 adjoin one another on a side facing the cavity 18 on a third groove 32. Overall, the sealing threshold area 12 has three grooves. The sealing threshold area 12 can also have more than three grooves. The further grooves can be arranged on the side or surface of the first wall and/or the second wall facing the cavity 18 or can be introduced therein.

Further is over Fig. 1 and Fig. 2 It can be seen that the first wall and the second wall 20, 22 of the adjacent walls of the sealing threshold area 12 form a bead, in particular of the sealing device 10. The first wall 20 and the second wall of the at least two adjacent walls 20, 22 are arranged next to one another in such a way that the sealing threshold area 12 is triangular in cross section. Furthermore, the cavity 18 also has a triangular shape in cross section. The third wall 24 in particular forms a base area of the triangular sealing threshold area 12. The cavity 18 can also have a different shape, for example a rectangular or round or elliptical or polygonal shape.

In relation to Fig. 2 The geometry of the sealing threshold area 12 will be discussed in more detail. The first wall 20 is arranged inclined at a predetermined angle α to a width direction or a transverse plane of the sealing device 12. The first wall 20 can be arranged at the predetermined angle α between 30° and 60°, preferably between 35° and 55°. Particularly preferably, the first wall 20 is arranged inclined at the predetermined angle α of 50° to the width direction. Based on a vertical direction, which extends in particular perpendicular to the main extension direction or width direction, the first wall 20 can be at a further predetermined angle between 30° and 60°, preferably between 35° and 55°, particularly preferably from 40° to the vertical direction of the seal threshold area 12 be arranged inclined. The second wall 22 is arranged inclined at a predetermined, in particular second, angle β to the width direction or the transverse plane of the sealing device 12. The second wall 22 can be arranged at the predetermined angle β between 30° and 60° inclined to the width direction. Particularly preferably, the second wall is arranged inclined at the predetermined angle β of 38° to the width direction. Based on the vertical direction, the second wall 22 can be arranged inclined at a further predetermined angle between 40° and 60°, preferably between 50° and 55°, particularly preferably of 52° to the vertical direction of the seal threshold area 12.

Further is Fig. 2 it can be seen that an end face 34 of the sealing base region 16 is arranged inclined to the width direction at a predetermined angle. In particular, the end face 34 can be beveled. The end face 34 of the sealing base area 16 can be arranged at a predetermined angle γ between 90° and 120°, preferably between 100° and 110°, particularly preferably inclined by 104°, in particular away from the base area or towards the width direction.

Furthermore, the sealing device 10 has a predetermined height H in a vertical direction of the sealing device 10. The height H of the sealing device 10 is less than 20 mm. Preferably it has Sealing device has a height H of 17.5 mm. Furthermore, the sealing base region 16 has a predetermined height h in the vertical direction of the sealing device 10. The height h of the sealing base area 16 is in particular between 2 mm and 10 mm, in particular between 3 mm and 7 mm, preferably 5.5 mm. Furthermore, the first wall 20 and the second wall 22 have a wall thickness between 2 mm and 10 mm, in particular between 3 mm and 7 mm. The first wall and the second wall, which adjoin one another at the apex 30, preferably have a wall thickness of 3 mm. The third wall 24 of the bottom area 16 has in particular the height h of the sealing bottom area 16.

In Fig. 3 the sealing base area 16 is shown enlarged in a cross-sectional view. The sealing base area 16 has several depressions 36. The depressions 36 are arranged on a surface or side of the sealing device 10 facing away from the cavity 18 and/or the seal support area 14. The depressions 36 are arranged next to one another at a predetermined distance from one another along the sealing base area, in particular in the width direction. The depressions extend in the main extension direction of the sealing device 10. Furthermore, the depressions 36 have a U-shaped or rectangular or square shape or contour, in particular in cross section. In other words, the depressions are U-shaped or rectangular and extend in the main extension direction of the sealing device 10. The sealing device 10 has a total of five depressions 36. However, the sealing device 10 can also have more or fewer than 5 depressions 36. Furthermore, a surface facing the base region, in particular a base surface of the sealing device 10, of the sealing base region 16 has a predetermined surface roughness or further grooves. The surface roughness is formed in particular by further grooves 38.

The seal support area 14 is wedge-shaped. Furthermore, the seal support area 14 includes two slope areas 40, 42. A first slope area 40 borders the second wall 22 of the Seal threshold area 12. The first slope region 40 has a smaller slope than the second wall 22 of the seal threshold region. The second slope area 42 borders the first slope area 40. The second slope region 42 has a greater slope than the first slope region 40. In other words, the seal support region 14 is divided into at least two regions - the first slope region 40 and the second slope region 42 - which have different slopes. In particular, the first slope region 40 and the second slope region 42 extend perpendicular to the main extension direction, rather than in the width direction. In particular, the first slope region 40 is designed to be longer in the width direction than the second slope region 42. In other words, the first slope region 40 is wider than the second slope region 42.

Furthermore, the seal support area 14 has a groove 43 which extends in the main extension direction of the seal support area 14. In other words, the groove 43 can extend at least partially, i.e. completely or partially, in the main extension direction. The groove 43 is arranged on the first slope region 40 of the seal support region 14. The groove 43 is preferably arranged on a surface of the seal support area 14 facing away from the bottom area or the bottom surface of the sealing device 10. The groove 43 serves in particular for attaching screws, for example, and gives the user a certain stability, particularly during assembly, which can make assembly of the sealing device 10 easier.

Fig. 4 shows the sealing device 10 with a part of the building closure element 44 resting on the sealing support area 14 of the sealing device 10 in a cross-sectional view. In the closed position of the building closure element 44, the building closure element 44 rests on the sealing support area 14. In particular, a support surface of the seal support area 14 is larger than the area of the building closure element 44, which rests on the seal support area 14. This is where the building closure element lies 44 on the first slope area 40 of the seal support area 14. In particular, the first slope region 40 is longer than a thickness or width of the building closure element 44 resting on the seal support region 14. Furthermore, the sealing threshold region 12 rests on the building closure element 44, in particular on a building closure element width side of the building closure element 44. In other words, in the closed position of the building closure element 44, the sealing threshold area 12 borders on a surface or side, which in particular corresponds to a width side of the building closure element 44.

Fig. 5 shows schematically a frame base 46 of the building closure device and the sealing device 10 adjacent or adjacent to the frame base 46 in a top view. The sealing device 10 extends from the frame foot 46 to a frame foot opposite the frame foot 46 of the building closure device (in Fig. 5 Not shown). A width of the sealing device 10 is adapted to a width of the frame feet 46 of the building closure device.

Fig. 6 to Fig. 8 show the assembly method of the sealing device 10 of a building closure device. The sequence of images in the individual figures is on self-explanatory. Nevertheless, in the context of Fig. 6 to Fig. 8 The assembly method, in particular the assembly steps for assembling the sealing device 10 of the building closure device, will be discussed in more detail.

Fig. 6 shows the building closure equipment. The building closure device is designed as a garage door. In the embodiment of Fig. 6 the garage door is designed as a sectional door 48. The sectional door 48 has a door leaf 50 and a guide device 52 for guiding the door leaf 50 between a closed position, which can also be referred to as a closed position, and an open position, which can also be referred to as an open position. In Fig. 6 the door leaf 50 is moved from the closed position to the open position, as indicated by the arrow.

The door leaf 50 has several slats or panels 54 that are articulated to one another. In the exemplary embodiment shown, a total of 4 panels 54 are provided. The number of panels 54 and their width can vary depending on the width of the opening or gate opening 56 to be closed. Furthermore, the building closure device has a guide device 52. The guide device 52 includes a guide which includes two guide rails 58, 60. The door leaf 50 is held displaceably between the guide rails 58, 60. In particular, the door leaf 50 is suspended on the guide, in particular on the two guide rails 58, 60. Furthermore, the building closure device has at least two frame bars 62, 64 lying opposite each other, which limit or frame the opening 56. The two frame spars 62, 64 extend perpendicular to a floor area 66 of the building closure device. The respective frame spar 62,64 each has a guide area which is designed to guide the door leaf 50. The management areas can form part of the management device 52. When opening or closing the door leaf 50, the door leaf 50 is guided from the open position into the closed position or from the closed position into the open position by means of the guide device 52, in particular along the two guide rails 58, 60 and the guide areas of the frame bars 62, 64.

The sectional door 50 also has the sealing device 10. The sealing device 10 is to be arranged in the area of the opening 56 Fig. 6 indicated by the oval border. To do this, the door leaf 50 must be moved into the open position so that the floor area 66 is exposed. The sealing device 10 is placed or arranged between the frame bars 62, 64, in particular between the frame feet. It is important to ensure that the floor area 66, on which the sealing device 10 is to be arranged, is free of impurities, such as dust or sand or dirt or stones or leaves. These subunits must be removed prior to arranging the sealing device 10 on the floor area 66, for example using a hand brush or a broom. Furthermore, it must be ensured that the sealing device 10 lies flat or level on the floor area 66 and in particular does not bulge or protrude from the floor area 66 at the respective ends or end faces of the sealing device 10.

In Fig. 7a ) it is indicated that the sealing device 10 is to be arranged on the bottom region 66 in the opening 56. However, the length of the sealing device 10 is even wider or longer than a width B of the opening 56. The width B of the opening 56 corresponds to a distance between the frame rail 62 and the frame rail 64. The width B of the opening 56 is wider than a frame dimension or Clear frame size of the building closure device. The width B is preferably 36 mm wider or longer than a frame dimension or clear frame dimension of the building closure device. In order to adapt the width of the sealing device 10 to the width B of the opening 56 of the building closure device to the width B of the opening, the sealing device 10 can be cut off at one end, as shown in section b). For example, the width B of the opening can correspond to the width of the frame size plus an additional 36 mm. The frame size can be less than or equal to 3000 mm or greater than 3000 mm. For this purpose, for example, a knife, in particular a carpet knife, can be used. Section c) illustrates how the length of the sealing device 10 is to be adapted to corresponding widths of different widths of the building closure devices, in particular openings 56 of the building closure devices. Furthermore, before arranging the sealing device 10, the sealing device 10 is drilled with drill holes, which are arranged in particular along the groove 43 at a predetermined distance from one another in the main extension direction of the sealing device 10. For this purpose, 68 boreholes, each with a predetermined diameter, preferably with a diameter of 5 mm, are drilled using a drill.

In section d), the position of the sealing device 10 on the base area 66 between the frame bars 62, 64 is marked or drawn using a spirit level 70. In section e), the sealing device 10 is arranged on the marking 72 or on a marked line on the floor area 66. In section f), the previously drilled boreholes of the sealing device 10 are marked on or on the floor area 66. For this purpose, for example, a pin can be inserted through the drill holes and thereby a mark can be created or provided on the floor area 66. Furthermore, a marking 74 opposite the marking 72, in particular on the side opposite the sealing device 10, is drawn or marked on the bottom region 66. The marking 72 and the marking 74 opposite the marking 72 mark or indicate the width of the sealing device 10. In section g), the marked drill holes 76 are drilled into the bottom area 66, in particular with a drill hole diameter of 8 mm. In section h), the impurities created after drilling the bottom area 66 are removed. These impurities can be removed using a hand broom, for example. In section i) 76 dowels 78 are inserted into the drill holes.

In Fig. 8 In section a), the sealing device 10 is arranged on the bottom region 66 in the opening 56 at the location intended for the sealing device 10. This checks whether the sealing device 10 can be placed precisely in the opening 50 on the bottom area 66. In section b), a further parallel marking is drawn parallel to the respective markings 72, 74 at a predetermined distance from the respective marking 72, 74. The further parallel markings are arranged between the markings 72, 74. The further parallel markings are arranged in particular at a distance of 10 mm from the respective markings 72, 74. In Section c), the floor area 66 between the markings 72, 74 is moistened or sprayed with water. In section d), an assembly sealing adhesive is applied along the other parallel markings. In section e), the assembly sealing adhesive is distributed in a zigzag shape between the other parallel markings. In section f), the sealing device 10 is applied or arranged on the floor area, in particular on the area wetted by the assembly sealing adhesive. In section g), the sealing device 10 is pressed against the bottom area 66. In section h), the sealing device 10 is additionally fastened with fastening elements, in particular screws. To do this, screws are inserted into the drill holes provided and screwed tight. In section i), additional assembly sealing adhesive is applied to the respective end faces of the sealing device 10, particularly in the area of the frame feet. In section j), the sectional door 50 is initially held in the open position for a predetermined period of time, in particular 2 hours. The sectional door 50 is then transferred from the open position to the closed position and remains in the closed position for a further predetermined period of time, in particular 10 hours.

Overall, the invention describes a sealing device or storm threshold made of EPDM to keep standing water out of the garage. For this purpose, the rubber profile is glued to the floor with an assembly sealing adhesive. Furthermore, if possible, an additional screw connection with stainless steel screws is provided, as the adhesive can settle or shrink over time. The seal geometry is designed so that the sealing device has a flat design with accessibility. In particular, the sealing device has a height with adhesive of less than 20 mm. Furthermore, a bead is designed with a hollow chamber in order to save material and to experience less resistance when driving over a passenger car. At the same time, the webs around the hollow chamber have grooves, which ensure defined and uniform deformation. In addition, hollow chambers can be formed on the underside of the seal so that the applied adhesive can form the correct adhesive layer thickness. Furthermore, a geometry of the sealing device, which is designed in particular as a floor seal, can be designed for sectional garage doors. In addition, the sealing device can have a profile width that is tailored to the frame feet. Furthermore, the sealing device can have a continuous groove for attaching the screws. Furthermore, the contour of the bevels of the sealing device can be selected so that water always flows in the direction “out of the garage”.
