Gate with movable gate segments

Abstract

In a gate (100) with at least two gate segments (10) which are movably connected to each other via hinge elements, each gate segment (10) has a profile frame (20) which defines a segment plane (E) and is fitted with at least one panel (25). In each gate segment (10), the profile frame (20) is provided with a fire-resistant material (30) on at least one outer surface of the gate segment (10) with respect to the segment plane (E), and furthermore, two adjacent gate segments (10) are connected by a fire-resistant textile (35) spanning the transition area between the two gate segments (10).

Description

[0001] The present invention relates to a door comprising at least two door segments movably connected to one another via hinged elements, wherein the door incorporates measures to improve fire protection. In particular, the door according to the invention can be a folding door, a sliding folding door, a circular sliding door, or a sliding door.

[0002] Gates of the type described above are used to selectively open or close large sections of a facade or wall within a building. Depending on the design of the segments and their mobility, gates can be created that, despite the fact that they close larger openings, require relatively little space. This is the case, for example, with so-called sliding-folding gates, as the individual segments are retracted or extended in an accordion-like folding movement, but remain within the area of ​​the folding gate, thus requiring no additional space on the sides.

[0003] The aforementioned sliding folding doors offer particular advantages when a building's facade needs to be opened or closed over a large area within a short period of time. However, doors of this type can also be used inside buildings to separate rooms or areas from one another.

[0004] Particularly when such a door is installed inside a building, the door has another important function with regard to fire protection. Since, as already mentioned, such doors usually close relatively large openings, they represent large-area connections between two adjacent rooms or areas. In the event of a fire, the door is generally a weak point compared to the surrounding wall, in that the area around the door is the most likely place for a fire to spread from one room to the next. This is especially true when the door is open, but even when the door is closed, fire and smoke will primarily spread through the area around the door.Accordingly, fire protection for doors and gates is of great importance, as these are crucial for determining how quickly fire and / or smoke can spread within a building in the event of a fire.

[0005] Generally, so-called fire doors are often made of special materials that are heat-resistant and retain their structural integrity in the event of a fire. The surfaces of the doors, in particular, are made of special materials or coated with special fire-resistant coatings to better withstand the high temperatures.

[0006] However, with gates of the type described above, there is a fundamental problem that, due to the movable connection between the multiple gate segments, there are always weak points that must be specially designed in order to meet the requirements of efficient fire protection.

[0007] The present invention is based on the object of providing a possibility of improving the fire protection of such doors, while at the same time keeping the associated expenditure to a minimum.

[0008] The object is achieved by a gate having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

[0009] The present invention is based on the use of conventionally constructed door segments consisting of a surrounding profile frame fitted with at least one panel. The profile frames provide the individual segment with the required stability and are typically made of metal, particularly steel. The panels closing the open profile frame can then each be designed in different ways, with numerous possibilities for implementing panels that exhibit the desired fire protection properties. The present invention then primarily focuses on measures that improve the fire protection properties of the frame construction and the door as a whole in the transition area between two adjacent door segments.

[0010] Thus, for each door segment, each having a profile frame secured to a segment plane and fitted with at least one panel, the profile frame is provided with a fire-protection material on at least one outer surface of the door segment relative to the segment plane, and two adjacent door segments are connected by a fire-protection textile spanning the transition area between two door segments. The measures according to the invention result in the transition areas between two door segments, which generally represent the weak point of the door with regard to the desired or required fire protection, being specially protected, thus significantly increasing the fire protection properties of the door overall.

[0011] According to the present invention, a door is proposed with at least two door segments which are movably connected to one another via joint elements, wherein each door segment has a profile frame which defines a segment plane and is equipped with at least one panel, and wherein in each door segment the profile frame is provided with a fire protection material on at least one outer surface of the door segment with respect to the segment plane, and two adjacent door segments are connected with a fire protection textile spanning the transition area between two door segments.

[0012] The joint elements that connect two adjacent door segments can, in particular, be hinge elements arranged on the profile frame, which then pivotally connect the door segments. In this case, it is preferably provided that the fire protection material, with the exception of the hinge elements, extends continuously around the perimeter of the profile frame. The fire protection is only interrupted in the area of ​​the hinge elements, in which case, if necessary, a fire protection material of a lower thickness, e.g., approximately 5 mm thick, can be arranged between the profile frame and the respective hinge element.

[0013] In principle, the fire protection material can be installed on both the outside and inside of the door. However, it is preferred that the fire protection material be installed on the same side of each door segment for the entire door.

[0014] To protect the fire protection material and to optimize the fastening and appearance of the door, it can also be provided that the door segments each have an additional cover for the fire protection material. This is preferably detachably attached to the associated profile frame, e.g., screwed to it. When using the aforementioned cover, it can be particularly preferably provided that it is first glued to the corresponding fire protection material and then attached to the profile frame as a structural unit. The cover can overlap the edge areas of the panel and, if necessary, also contribute to its support. In particular, however, the coupling to the panels equipped with independent fire protection measures is optimized.

[0015] The fire protection material which is arranged on the profile frame in accordance with the invention can be, for example, a material made of calcium silicate or pressed rock wool.

[0016] As explained above, the interface or transition area between two door segments is additionally protected according to the invention by providing a fire protection textile spanning this transition area. This can also preferably be arranged on the same side of the door segments as the respective fire protection material, although in principle an arrangement on the opposite side would also be conceivable. Since a certain degree of flexibility must be provided here due to the mobility of the door segments relative to one another, the fire protection textile is preferably designed and dimensioned such that it connects two adjacent door segments to one another in a loop-like manner. The mobility of the door segments relative to one another is therefore not negatively affected by the additional fire protection measures according to the invention.

[0017] According to a first embodiment, the fire-protection textile can be clamped between an outer surface of the profile frame and the fire-protection material, with any joint elements preferably enclosing the fire-protection textile. Alternatively, it would be conceivable for the fire-protection textile to be fixed to an outer surface of the profile frame, in which case the fire-protection textile preferably encloses any joint elements.

[0018] The fire-resistant textile has a special protective function, particularly for seals provided at the transition area between two adjacent door segments. When the door is closed, these seals ensure that, for example, the flow of air and thus the spread of smoke is impeded. Such seals are generally made of EPDM and are relatively susceptible to high temperatures, such as those that can occur during fires. The fire-resistant textile provided according to the invention represents an additional protective measure that prevents the seals from being damaged prematurely in the event of a fire and thus losing their sealing function.

[0019] As already mentioned, the door according to the invention can be, in particular, a folding door, a sliding folding door, a circular sliding door, or a sliding door. The fire protection measures according to the invention generally lead to improvements, regardless of the way in which the door segments are movably connected to one another and how they move relative to one another when the door is opened or closed.

[0020] The invention will be explained in more detail below with reference to the accompanying drawings. They show: Figure 1 shows a side view of a folding door in which the fire protection measures according to the invention are to be used; Figure 2 shows a plan view of the Figure 1folding door shown; Figure 3 is an enlarged view of a transition area between two adjacent door segments with the fire protection measures according to the invention according to a first variant, wherein the fire protection textile is arranged on the side opposite the hinge; Figure 4 is a Figure 3 analogous representation of the transition area between two door segments with fire protection measures according to a second variant; Figure 5a to Figure 3 analogous representation of the transition area between two door segments with fire protection measures, with the fire protection textile arranged on the side of the hinge; and Figure 6 a Figure 5 analogous representation of the transition area between two gate segments with fire protection measures according to a fourth variant.

[0021] The figures explained in more detail below show a folding door opening on both sides as an exemplary embodiment of the invention, with each door half consisting of two door segments according to the invention. However, it should be noted that the inventive concept can also be applied to other door designs, in particular to all designs that utilize door segments based on the frame construction described in more detail below.

[0022] The Figures 1 and 2The folding gate shown, generally designated by reference numeral 100, is used to selectively open or close a larger opening in a building façade (not shown in detail in the figures) or a wall within a building. Each gate half has two plate-like or wing-like gate segments, wherein in the illustrated embodiment, the left gate half is formed by gate segments 10 1 and 10 2 and the right gate half is formed by gate segments 10 3 and 10 4. In the closed state, which is shown in the figures, all gate segments 10 1 to 10 4 are aligned in one plane with one another and completely close the corresponding opening of gate 100.

[0023] The gate segments 10 1 - 10 4 of each gate half are connected to one another via hinges 50 or, in the case of the two outer gate segments 10 1 and 10 4, are coupled to a gate frame 110 via hinges 50, so that when the gate 100 is opened or closed, the outer or first gate segment 10 1 or 10 4 can be pivoted about a vertical axis. The adjoining second segment 10 2 or 10 3 of each gate half is connected to the respective outer segment 10 1 or 10 4 via the aforementioned hinges 50 and is guided on the side opposite the hinges 50 by means of guide elements 115 on a guide rail 120 running along the top side of the gate 100 and extending in a straight line (in other gate types such as circular sliding gates the guide has a curve, in folding gates with 180° opening it has a kink).Both segments 10 2 and 10 3 can thus slide along this guide rail 120, but at the same time can also be rotated about a vertically extending axis relative to the guide element 115 running along the guide rail 120.

[0024] Thus, when the outer door segment 101 or 104 is first pivoted about the corresponding rotation axis during the opening of the door 100, this results in the respective inner folding door segment 102 or 103 also performing a pivoting movement and simultaneously being pulled outward along the guide rail 120 with its end facing away from the frame 110. This folding movement ends in a state in which both segments 101 and 102 or 103 and 104 of each door half are aligned perpendicular to the plane of the door opening, thus opening the door 100 to its maximum extent. This basic design of corresponding folding doors has been known for some time.

[0025] The mobility of the individual door segments 10 relative to one another required for the opening and closing movement explained above results in gaps or openings occurring at the transition areas due to the corresponding movable coupling, which can negatively impact the fire protection properties of the door 100. Although seals, described in more detail below, are generally provided here, these are usually made of a material that can only withstand the high temperatures that occur in the event of a fire for a short time. With the help of the invention described in more detail below, it is ensured that suitable fire protection measures can also be implemented at these transition areas, which ultimately result in the door as a whole offering sufficiently high fire protection.

[0026] Each door segment 10 initially has a surrounding profile frame 20, which in the illustrated case has a rectangular configuration divided by two horizontally extending cross bars 28. This results in three sub-areas, each filled with a corresponding panel 25. Panels of various constructions can be used for this purpose and, in the case of fire protection, constructions that are sufficiently heat-resistant are naturally preferred. Panels that meet such requirements are known from the prior art and can be used analogously in the present case. As already mentioned, the invention primarily concerns the question of how fire protection can be improved in the transition area between two movably connected door segments 10.

[0027] The profile frame 20 itself is usually made of metal, for example aluminum or steel, and has, as shown by Figure 3 in section perpendicular to the plane E of the gate segment 10, according to the illustrations, an approximately square, hollow configuration. In the embodiments of the Figures 3 and 4 The wall 21 facing the outside of the door is slightly extended in the direction of the opening enclosed by the frame 20 and joined to a folded end portion of the wall 22 facing the opening, forming a flange-like support portion 21a facing the corresponding panel 25. This serves to support the panel 25, with the panel 25 being secured to the opposite side of the door in the illustrated embodiment using a cover 40, which will be described in more detail later. In principle, however, the panels 25 can also be secured in other ways.

[0028] On the side walls 24, which are opposite the walls 22, wedge-like seals 47 are also provided, which, when the door 100 is closed, interact with the respective seal 47 of the adjacent door segment 10. In the Figures 3 and 4 In the closed state shown, the two seals 47 seal the intermediate area between two adjacent segment frames 20 and serve to meet the requirements for pinch protection. Such seals are typically made of EPDM (ethylene propylene diene), a synthetic rubber that provides good sealing properties. On the other hand, this material has inadequate fire protection properties.

[0029] In order to optimise fire protection, it is now provided that a fire protection material 30 is arranged on one of the two outer sides 21, 22 of the frame 20 (with respect to the plane E of the door segments 10), with the aid of which, in particular, the fire protection properties of the frame 20 itself are improved.

[0030] This fire protection material 30 is a material based on calcium silicate or pressed rock wool, which covers the corresponding inner side 21 of the frame 20 in a shell-like configuration as completely and circumferentially as possible. Figures 3 and 4 The fire protection material 30 is arranged on the side of the frame 20 opposite the associated hinge 50. However, as can be seen from the above explanation and the illustration in the Figures 1 and 2can be removed, the hinges 50 and any further guide or holding elements 115 are arranged alternately on the two sides of the door segments 10. Since the fire protection material 20 is always arranged on the same side of the frame 20 with regard to an individual door segment 10, this leads to the fire protection material 30 being temporarily interrupted in the area of ​​the hinges 50 or the other guide elements 115. In this case, it can be provided that a fire protection material with a smaller thickness of approximately 5 mm is provided between the hinge 50 or guide element 115 and the associated frame surface in order to also improve the fire protection properties of the overall construction. All other areas of the corresponding frame 20, on the other hand, are covered all around by the fire protection material 30, so that the most completely closed protection possible is achieved.The thickness of the fire protection material 30 in these areas is approximately 10 to 30 mm.

[0031] The arrangement or fastening of the fire protection material 30 to the frame 20 can be carried out in different ways, wherein it is preferably provided that the fire protection material 30 is provided with an additional cover 40 for protection on the one hand, and for optical reasons on the other. In the embodiments of the Figures 3 and 4the cover 40 is formed by a metallic web with an angled cross-section, which corresponds in terms of its overall shape to that of the frame 20 and - in the illustrated embodiment - is screwed to the frame 20 from the inside of the door using screws 45. In this case, it can be provided that the fire protection material 30 is first attached to the cover 40, for example, glued to it. The resulting structural unit consisting of cover 40 and fire protection material 30 is then screwed to the frame 20. This results in a particularly stable construction, which enables the cover 40, which is extended towards the inside of the respective door segment 10, to simultaneously serve to fix the panel 25. As already mentioned, however, other measures for holding the panel 25 are also conceivable.

[0032] In principle, however, this first step of the measures according to the invention results in the frame 20 of each door segment 10 being provided with a fire protection material 30 almost completely closed all around, and thereby the fire protection properties of the segment 10 itself are significantly improved.

[0033] In order to further improve the transition area between two adjacent gate segments 10, the Figures 3 to 6A schematically illustrated fire protection textile 35 is provided, which bridges the transition area accordingly. This fire protection textile 35 consists of a material such as is known, for example, from fire protection blankets, and results in the connecting area between two door segments 10 being additionally sealed against gases on the one hand, and the components of the transition area behind it, in particular the seals 47, being additionally thermally protected on the other. In order to maintain the mobility of the door segments 10 relative to one another, it is preferably provided that the fire protection textile 35 bridges two adjacent door segments 10 in the manner shown in loops, wherein the size of the loops can also be significantly larger than in the selected representations.It is crucial that even when the door segments 10 are completely pivoted relative to each other, the fire protection textile 35 still allows sufficient space for the segments 10 to move relative to each other.

[0034] The fastening of the fire protection textile 35 is carried out in the first two embodiments of the Figures 3 and 4 on the same side on which the fire protection material 30 is applied to the respective segment frames 20, and thus on the side opposite the hinges 50. In this case, the previously explained screw connection can again be used to fasten the fire protection material 30 (if necessary including the cover 40) to the frame 20, whereby on the one hand the edge areas of the fire protection textile 35 can be fixed between the outer surface of the frame and the fire protection material 30 (variant according to Figure 3 ) or on the other hand can be attached to the outside of the cover 40 (variant according to Figure 4). In the second case, the fastening of the fire-resistant textile 40, which should extend over the entire height of the door segments 10, can be improved by means of an additional web 37, which is also fixed to the outside of the cover 40 by means of the screws 45.

[0035] Since the fire-protection textile 35 preferably interacts with the fire-protection material 30, it should ideally always be arranged on the same side of the door as the fire-protection material 30. This means that in at least some transition areas, the fire-protection textile 35 is provided on the same side as the hinges 50 of the door. Two corresponding embodiments for this are shown in the Figures 5 and 6 shown.

[0036] In the variant according to Figure 5 is analogous to Figure 3The fire-protection textile 35 is clamped between the outer surface of the frame and the fire-protection material 30. In this case, the loop of the fire-protection textile 35 is arranged within the area of ​​the hinge 50 and is accordingly dimensioned so small that it does not collide with the hinge parts.

[0037] Figure 6 shows a variant in which analogous to Figure 4 The fire-protection textile 35 is in turn fixed to the outside of the cover 40 by means of a separate web 37 or a retaining strip. In this case, the fire-protection textile 35 completely overlaps the hinge 50 or covers it towards the outside and is accordingly relatively large in order to still allow the door segments 10 to pivot relative to each other.

[0038] Deviating from the illustrations, it would also be conceivable in principle to arrange the fire protection textile 35 on certain sides of the door segments independently of the position of the fire protection material 30.

[0039] Ultimately, the measures described lead to a significant improvement in the fire protection properties of a door. A key advantage here is that these measures can be implemented with relatively little effort on existing standard constructions. This means that existing door segments for movable doors can be used, which can then be supplemented with the fire protection material 30 and the fire protection textile 35 as described above, ultimately resulting in a door that, overall, has good fire protection properties. Starting from a common basic profile, either simple frames or frames and thus door segments specifically optimized for fire protection can be provided. This leads to reduced manufacturing costs, as the effort required to store the corresponding raw materials is significantly reduced overall.
