AI Technical Summary
Existing door systems, particularly horizontally opening gates like sliding and folding gates, face challenges in achieving sufficient thermal insulation while maintaining structural stability, especially when subjected to high loads during opening and closing, limiting their size and frequency of use.
A door segment design featuring a single-piece profile frame with thermal insulation applied on one or both outer surfaces, where hinges and other load-bearing parts are directly attached, ensuring the insulation extends continuously around the frame circumference, except at hinge locations, enhancing stability and insulation without compromising structural integrity.
The solution provides improved thermal insulation comparable to prior art methods while significantly increasing structural stability, allowing for larger and more frequently used gate systems with reduced manufacturing complexity and cost.
Description
[0001] The present invention relates to a door segment intended for forming a single- or multi-part door and optimized with regard to its thermal insulation. For example, the door segment according to the invention can be used, in particular, to create horizontally opening industrial door systems, such as folding doors, sliding folding doors, sliding doors, or circular sliding doors.
[0002] Every gate system usually has one or more segments, which are also referred to as gate leaves. Depending on the type of gate system, these leaves can be pivoted or, for example, pivoted and moved, so that they can be moved from a closed position to an open position. A segment usually consists of a circumferential profile frame equipped with at least one panel. In larger segments, the profile frame is often divided into several sections by one or more cross bars, with each section being able to be fitted with its own filling. Glass or sheet metal panels are usually used for this, and depending on the material and design, they have different thermal insulation properties.
[0003] Since such door systems are often part of a building facade, it is important to ensure that the door provides sufficient thermal insulation to thermally decouple the interior of the building from the exterior. However, not only the insulation values of the aforementioned glass or sheet metal panels must be considered; the insulation value of the door system as a whole is also comprised of the values for the frame construction, the seals, and the fillings. The present invention particularly addresses the question of how the thermal insulation of the frame construction of a door segment can be optimized.
[0004] In this context, two approaches are essentially known from the state of the art.
[0005] On the one hand, door segments are provided that consist of uninsulated steel or aluminum profiles. In this case, the frame construction does not contribute to the thermal insulation of the door, which is why such constructions often cannot meet certain insulation requirements.
[0006] As an alternative to this, it is therefore known to connect two metal profile halves, which are arranged parallel to one another in a direction perpendicular to the plane of the segment, via a thermal break. This thermal break usually consists of fiber-reinforced polyamide profiles, with the resulting construction (i.e. the metal profile halves connected via the polyamide profile) then representing the actual profile frame of the door segment, which serves to hold the panels. A corresponding construction is described, for example, in EP 2 573 307 A1. DE 1 973 124 further describes a multi-part construction for a fire-resistant door in which additional profiles and insulation panels are provided on the outside of a two-part sheet metal casing.
[0007] While the solution just described can achieve satisfactory thermal insulation, it does require a relatively high level of effort to manufacture the frame structure. Even more problematic, however, is that in horizontally opening gates, such as sliding and folding gates, where multiple gate segments are movably connected via hinges, the corresponding hinges are attached alternately on the outside and inside of the frame structure. This results in the flow of force under load passing through the thermal break of the profile frame structure, reducing the strength of the gate leaf. It has therefore been shown that this state-of-the-art solution only allows gates of a limited size and height, as well as with low opening frequencies, as otherwise the load on the structure would be too high.However, this solution is not suitable for larger gate systems where high forces can occur during the opening or closing process.
[0008] Furthermore, a solution for a window with two window segments that can be moved relative to each other is known from the prior art. Each segment has an aluminum base profile provided on at least one side with an insulating profile for thermal insulation. In this solution, described in KR 200 434 719 Y1, the insulating profiles are designed such that they are each pushed longitudinally onto corresponding projections of the base profile.
[0009] The present invention is based on the object of providing an improved possibility for the thermal insulation of door segments, in which - ideally with a relatively low expenditure - the disadvantages described above are avoided and in which the door segments can be used to realize, for example, a folding door.
[0010] The object is achieved by a gate segment having the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
[0011] The inventive solution is based on the idea that, in contrast to the prior art solution, the individual segment frame does not consist of thermally separated partial profiles that are then connected to one another via thermal insulation that is not sufficiently mechanically stable, but rather that an external insulation shell is applied to a conventional segment frame without thermal separation, to which hinges and all other load-bearing parts are attached. Hinge elements for pivotably connecting the door segment to a casing and / or another door segment are arranged on the profile frame, wherein the insulation, with the exception of the hinge elements, extends essentially continuously over the circumference of the profile frame, and wherein the hinge elements are arranged on opposite sides of the door segment with respect to the segment plane.In contrast to the state-of-the-art solution, the resulting insulation layer is located inside or outside the door segment and, in particular, does not affect the structural functional properties of the door segment. Furthermore, there are advantages regarding the production of the door segment, as insulated or non-insulated frame designs can now be realized relatively easily, based on the same basic profile frame design.
[0012] According to the present invention, a gate segment for forming a single-part or multi-part gate is proposed, wherein the door segment has a profile frame which defines a segment plane and is equipped with at least one panel, and wherein according to the invention the profile frame is designed as a single piece in a section perpendicular to the segment plane and is provided with thermal insulation on at least one outer surface of the door segment with respect to the segment plane, wherein hinge elements for pivotably connecting the door segment to a frame and / or a further door segment are arranged on the profile frame, wherein the insulation, with the exception of the hinge elements, extends essentially in a closed manner over the circumference of the profile frame, and wherein the hinge elements are arranged on opposite sides of the door segment with respect to the segment plane.
[0013] It has been shown that, using the inventive concept, insulating properties for the segment frame can be achieved that are comparable to or even exceed those of the prior art solution. However, compared to the prior art solution, the frame structure is significantly more stable, so that even larger gate systems can ultimately be easily implemented using the inventive gate segments.
[0014] The insulation provided according to the invention on the outer surface of the profile frame preferably extends completely around the entire circumference of the profile frame, with the exception of the hinge elements. Depending on the material used, it generally has a thickness of approximately 10 mm to 30 mm.
[0015] The insulation is therefore only interrupted by the hinge elements (and any other bearing or guide elements provided on the profile frame), although it may be possible to provide additional insulation measures in the area of the hinge elements or guide elements. For example, in this area between the profile frame and the respective hinge element or guide element, insulation material with a lower thickness, for example with a thickness of around 5 mm, can be provided, although the hinge element is still attached directly to the profile frame. This means that elements intended for attaching the hinge element, such as screws, penetrate any existing insulation material and interact directly with the hinge element and the profile frame.
[0016] It is possible to glue the thermal insulation provided according to the invention to the corresponding surface of the profile frame. A detachable fastening is also conceivable, in which case it can be provided that the thermal insulation is screwed to the profile frame.
[0017] To protect the insulation material and to optimize the appearance of the door segment, it can also be provided that a cover is additionally provided for the thermal insulation. According to one variant, the cover, together with the thermal insulation, is detachably attached to the profile frame, in particular screwed to it. In this case, it is particularly preferred that the cover is first glued to the thermal insulation and then the resulting assembly is attached to the profile frame. This procedure has the advantage that the cover and the insulation material can be easily removed during maintenance work.
[0018] If, however, greater attention is paid to the appearance of the resulting door segment, an alternative solution could also be provided for the cover to be attached to the thermal insulation without the use of tools and / or detachably. In this case, it would be particularly conceivable for the insulation to be first attached to the profile frame and then the cover to be clamped or snapped onto the thermal insulation. The cover can, in particular, overlap the edge areas of the corresponding panel and, if necessary, also contribute to its reliable support.
[0019] For larger door segments, it can be provided that they have at least one additional rung, which connects opposite sides of the profile frame, thus dividing the door segment into several sub-segments. In this case, it can also be provided that, similar to the frame, an outer surface of the rung is provided with thermal insulation. The method of arrangement and fastening, as well as the use of a corresponding cover, is then analogous to the solutions described above for the segment frame.
[0020] Each panel can be formed by a parallel arrangement of two or more plate-like elements. These can, in particular, be glass panes or sheet metal elements, as is known from the prior art.
[0021] As already mentioned, the door segment according to the invention can be used in particular to create a door with one or more segments. A door according to the invention preferably has at least two door segments that are movably connected to one another. In particular, this can be a folding door, a sliding folding door, a sliding door, or a circular sliding door.
[0022] 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 door segments designed according to the invention are used. Figure 2 shows a plan view of the Figure 1illustrated folding gate; Figure 3 shows an enlarged view of the design of the gate segments, wherein the insulation is attached to the inside of the gate segments; Figure 4 shows a further enlarged view of the gate segments designed according to the invention in the area of a hinge connecting two segments; Figure 5 shows a second embodiment of a folding gate with gate segments according to the invention, wherein the insulation is provided on the outside of the gate segments; Figure 6 shows an enlarged view of the gate according to Figure 5 in the area of the hinge; and Figure 7 shows a view of a third embodiment of a folding door according to the invention
[0023] 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.
[0024] The Figures 1 and 2The folding gate shown, generally designated by reference numeral 100, serves to selectively open or close a larger opening in a building façade (not shown in detail in the figures). 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 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.
[0025] 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.
[0026] 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.
[0027] The procedure described above for opening and closing the door 100 requires that the hinges 50 are arranged alternately for pivotally connecting the door segments 10 1 - 10 4 to each other and for fastening them to the frame 110. This is also shown in the enlarged illustration of Figure 3 visible. The hinges 50 connecting the outer segments 10 1 and 10 4 to the frame 110 are thus arranged on the inside of the door 100 in the illustrated case, whereas the hinges 50 connecting the outer segments 10 1 and 10 4 to the inner segments 10 2 and 10 3, respectively, are arranged on the outside of the door 100 in order to enable the folding movement described above for opening and closing the door 100.
[0028] However, this has the consequence that during the opening or closing of the gate 100, a force flow perpendicular to the plane of the respective gate segment 10 1 or 10 4 is present. The same applies to the two inner gate segments 10 2 and 10 3 , in which, on the one hand, the corresponding hinges 50 engage the outer side of the segment 10 2 or 10 3 and, opposite, on the inner side, the coupling to the guide rail 120 takes place with the aid of the guide elements 115.
[0029] The realization of larger gate systems is therefore only possible if the corresponding segments exhibit sufficient stability in a direction perpendicular to the plane of the respective segment. This is ensured by the invention described in more detail below, while simultaneously providing measures for optimized thermal insulation.
[0030] According to the present invention, a single door segment 10 according to the invention initially comprises a surrounding profile frame 20, which in the present case has a rectangular configuration, which is divided by two horizontally extending cross bars 28. This results in three sub-areas, each of which is filled with a corresponding panel, wherein in the illustrated embodiment the Figure 1It is provided that the lower sections of the door segments 20 are equipped with sheet metal panels 29, and that glass panels 25 are arranged in the upper sections. Naturally, the choice of material for the individual panels 25 and 29 is irrelevant with regard to the inventive solution, which concerns the thermal insulation of the frame construction. This is independent of the insulation of the panels 25 and 29, but contributes additively to the insulation value of the door segment 10 as a whole and should also be optimized accordingly. Furthermore, the number of cross bars 28 can also vary, or such bars 28 could possibly be omitted entirely.
[0031] The profile frame 20 can be made of aluminum or steel, for example, and has a roughly square, hollow configuration in section perpendicular to the plane E of the door 100, as shown in the illustrations. In the embodiment of the Figure 4The 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, so that a flange-like support portion 21a is formed facing the glass panel 25. This serves to support the glass panel 25, which in the illustrated embodiment is formed from three parallel panes 26, which are kept at a distance from each other by corresponding spacers 27. The fixing of the panel 25 to the inside of the door is carried out in the embodiment according to Figure 4with the aid of a cover 40, which will be described in more detail below, although the panels 25 and 29 could also be secured in another way. Furthermore, wedge-shaped seals 47 are provided on the side walls 24, which are opposite the walls 22, and which interact with the respective seal of the adjacent door segment 10 when the door 100 is closed.
[0032] The aforementioned hinges 50 and guide elements 115 are then each directly attached to the profile frame 20, so that the latter absorbs the forces acting from both sides (i.e., the inside and outside of the gate). Direct attachment here means that the components used for attachment—such as screws or the like—interact directly with the hinge 50 or guide element 115 and with the profile frame 20, which is constructed in one piece perpendicular to the plane of the gate segment 10, and there is no indirect connection, for example, via an intermediate element. This results in a stable configuration for the segment 10, which also enables the realization of larger gate systems.
[0033] In the procedure described so far, the door segment 10 according to the invention is similar to previously known constructions, which, however, do not have thermal insulation in the area of the frame 20. According to the present invention, thermal insulation 30 is now provided on one of the two outer sides 21, 23 of the frame 20 (relative to the plane E of the door segment 10), with the aid of which thermal insulation can now also be achieved in the area of the frame 20 itself.
[0034] In the first embodiment of the Figures 3 and 4For example, it is provided that the insulation 30 is applied to the inside of the frame 20, i.e., the side surface 23 of the frame 20 facing the interior of the building. This insulation 30 is an insulating material in a shell-like configuration, which covers the corresponding inside 23 of the frame 20 as completely and circumferentially as possible. This insulation 30 is only interrupted in those areas in which hinges 50 or guide elements 115 are provided on the inside of the frame 20, wherein, if necessary, an insulating material with a small thickness of approximately 5 mm can be provided between the hinge 50 or guide element 115 and the frame surface 23 in order to achieve at least a certain level of insulation here as well.All other areas of the frame inner side 23, however, are covered all around by the insulating material 30, so that heat transfer via the frame 20 is prevented or at least strongly suppressed.
[0035] The insulation material used can be foamed EPS (expanded polystyrene) or pressure-resistant XPS (extruded polystyrene). The insulation 30 preferably has a thickness of approximately 10 to 30 mm, which results in sufficiently high thermal insulation.
[0036] What is now crucial is that the insulating material 30 is provided on an outer surface of the frame structure 20, thus not impairing the structural properties of the frame 20 and thus of the door segment 10. This represents a decisive advantage over previously known multi-part frame structures, in which the sub-frames were connected to one another via an insulating material. Although very efficient insulation was achieved in this case, it was at the expense of the frame's stability. This problem does not exist with the solution according to the invention, although excellent insulating properties can still be achieved.
[0037] The arrangement or fastening of the insulation 30 to the frame 20 can be carried out in different ways, wherein it is preferably provided that the insulation 30 is provided with an additional cover 40 on the one hand to protect the corresponding insulation material and on the other hand for optical reasons. In the embodiment of the Figures 3 and 4The cover 40 is formed by a metal web with an angled cross-section, which corresponds in terms of its overall shape to that of the frame 20 and is screwed to the frame 20 from the inside of the door using several screws 45. In this case, it can be provided that the insulation 30 is first attached to the cover 40, e.g., glued to it. The resulting assembly consisting of the cover 40 and the insulation material 30 is then screwed to the frame 20. This results in a particularly stable construction, which allows the cover 40, which is extended towards the inside of the segment 10, to simultaneously serve as a holder for the glass panel 25, as shown in Figure 4 is visible. However, other measures for securing the corresponding panel 25 or 29 would also be conceivable.
[0038] Ultimately, the result is Figure 4recognizable construction, which allows the realization of extremely stable door segments 10, which also provide optimal thermal insulation with regard to the frame construction.
[0039] It should be noted that if the aforementioned crossbars 28 are present, they should be thermally insulated in a similar manner. In this case, too, appropriate insulating materials should be provided on the inside of the crossbars 28, concealed by a cover. The methods of fastening the insulating material and the cover are the same as for the frame 20.
[0040] The Figures 5 and 6 show a second embodiment of a folding gate 100 according to the invention, wherein identical elements are provided with identical reference numerals.
[0041] The essential difference in this second embodiment is that the insulation 30 is now arranged on the outside of the door frame 20, thus covering the outer surface 21. In this case, the insulation 30 is glued to the outer surface 21 of the frame 20 and is thus permanently connected to it. The cover 40 is then placed on the insulation 30 without tools and is detachably mounted and is either clamped to it or snapped onto it, which leads to a particularly attractive appearance of the overall construction, since in comparison to the solution of the Figures 3 and 4 no screw connections are visible.
[0042] The Figure 6The screw 55 visible serves to fasten the hinge 50 to the frame 20, whereby the hinge 50, as already mentioned, interrupts the insulation 30, although a thin insulation plate of a few millimeters - not shown in the figures - can be provided between the hinge and the outside of the frame.
[0043] In the variant of the Figures 5 and 6 The manner in which the cover 40 is attached means that it cannot absorb significant forces. In this case, this cover 40 cannot be used to additionally hold the glass panel 25 visible here. Accordingly, other measures must be provided to enable the attachment of the panel 25 to the frame 20. However, solutions already known from the prior art can be used here.
[0044] It is crucial that in this embodiment, too, all load-bearing parts, in particular the hinges 50 and the guides 115, are fastened directly to the frame 20 and that the frame is designed as a single piece in a section perpendicular to the plane of the gate segment 10, which in turn leads to the desired high stability of the overall construction.
[0045] As already mentioned, the inventive concept is independent of the type and design of the panels 25, 29 held by the frame 20. Thus, according to the representation of the Figure 7 It is also possible to use a two-layer panel 25 instead of a three-layer glass panel. The example shown here is very similar to the example of the Figures 3 and 4, whereby due to the reduced thickness of the panel 25, a corresponding adjustment of the cross-sectional shape of the insulation material 30 and the cover 40 is now carried out. In other respects, however, both embodiments are identical.
[0046] Ultimately, the solution according to the invention makes it possible to provide segments for the realization of different gate systems which, on the one hand, have a high level of stability and, on the other hand, are efficiently thermally insulated with regard to their frame construction.
[0047] Another advantage of the inventive concept is that no modifications to the frame itself are required to implement the inventive insulation of the frame construction. The inventive concept can therefore be applied to existing frame designs, ultimately making it possible to create either an insulated or non-insulated frame for a door segment based on a single basic profile. This, in turn, leads to reduced manufacturing costs compared to the prior art, as the manufacturing process and the effort required to store the corresponding raw materials are significantly simplified overall.
