Definitions

  • the present invention relates to an attachment shell system for a device for closing a wall opening of a building, in particular for an openable or non-openable window or for a door with at least one first, in particular at least partially curved along a longitudinal direction or extending at an angle, in particular at right angles or at an acute angle first cladding profile, which is designed and set up alone or together with further cladding profiles for cladding at least one frame section of a frame of the device, the first cladding profile having an inside facing the frame section in the intended installed state and an outside facing away from the frame section in the intended installed state.
  • the invention relates to a device for closing a wall opening in a building with such an attachment shell system.
  • composite windows and doors are now very often used in which the sash frame is made of a different material than the facing shell for it.
  • This type of construction has proven successful, among other things, because the area of the composite window or door that is exposed to the weather can be covered with a material that is less susceptible to the weather and is therefore durable. In contrast, a cheaper material can be chosen for the interior, which also has advantages in terms of appearance and feel. Furthermore, this enables an optimized thermal separation between the inside and outside.
  • Typical material pairings for such composite windows and doors are wood-aluminium, plastic-aluminium or similar. In the context of the present For the sake of ease of reading, only the term composite windows is used in the application, although this also expressly includes composite doors, as far as transferable.
  • Aluminum facings for composite windows are usually made from extruded or continuous cast profiles. These are mass-produced pieces that are straight along their longitudinal direction, i.e. along the extrusion direction, and are cut to size for the individual window. For right-angled corners, this is done at an angle of 45° to the longitudinal direction of the extruded or continuous cast profile in order to define the miter between two adjacent profiles. To produce a visually appealing facing and to prevent moisture from penetrating the space between the sash frame and the facing, the profiles that meet are welded in the miter area and then ground.
  • the method described above can in principle also be used if the angle between two meeting profiles is acute or obtuse.
  • the angle at which the profile is shortened must be adjusted accordingly.
  • the challenge when installing the facing shell is that the miter is lengthened, which also increases the length of the line weld.
  • this is more demanding for the installer, but on the other hand, the increased temperature input due to the longer weld seam promotes the build-up of internal stresses in the miter area and thus the risk of material distortion.
  • Bending causes material compression on the side of the profile facing the bending radius center and material stretching on the side of the profile facing away from the bending radius center. Compression on the inside can lead to distortions, which require increased sanding effort. Even if this sanding is carried out to a high quality, there is a risk that a subsequent surface coating, for example a powder coating, the application of a wood decor or an anodized coating, will not produce a homogeneous appearance, as the density and thickness of the material in this area is not homogeneous. Stretching on the outside, in turn, can lead to a weakening of the material and even the formation of (micro) cracks, which have a detrimental effect on both the appearance and the longevity of the facing shell. In practice, the above means that when bending extruded and/or continuous cast profiles, minimum bending radii must be observed, which arise individually from the width and design, in particular the cross-sectional design of the profile.
  • a double disadvantage arises from bending extruded or continuously cast profiles for geometry, for example with regard to the dimensional accuracy of the profile. Bending reduces the actual width of the profile by up to a few percent of the original width. This visual impairment is particularly significant when a curved profile directly adjoins a non-curved profile and two profiles of different widths are revealed to the viewer.
  • the second disadvantage concerns the attachment of the facing shell to the sash frame. On the side of the attachment shell facing the sash, recesses are often provided either in sections or through them, in which, among other things, fastening devices for fastening to the sash are arranged. Such fastening devices are usually clip devices or rotary holders.
  • the width of these recesses is defined by the manufacturers of the extruded or continuously cast profiles according to the standardized width of the fastening devices and in the unbent state of the profiles.
  • the recesses due to the narrowing of the profile described above, the recesses also become narrower and proper attachment of the profile to the sash frame is not possible or only possible additional manual effort can be guaranteed.
  • automatic setting of the clip devices and/or rotary holders is no longer possible due to the geometry changes in conventional round arches. These have to be set manually with great effort.
  • the bending process requires a lot of manpower and represents a significant risk from the point of view of occupational safety.
  • the extruded or continuous cast profile to be bent is usually heated by an experienced specialist with or over an open flame, thereby giving it the formability required for bending. This requires a great deal of sensitivity to achieve exactly the temperature window required for bending. If the profile is heated too much, there is a risk of undesirable weakening or damage to the material. For example, if an aluminum alloy or a plastic used for this purpose is heated above a certain temperature, an irreversible change in shape and/or structure can occur. The component heated accordingly is therefore scrap.
  • the desired bending radius on the finished component can only be achieved through a large number of iterative bending processes, each of which requires the bending machine to be preset accordingly. This is very complex. For more complicated geometries, e.g. with several different bending radii or If the bending radii vary on the same profile, this cost increases accordingly. In order to achieve different bending radii on one and the same profile, in addition to the complex adjustment work mentioned above, it may also be necessary to have a number of bending machines, bending molds and/or roller sets available, depending on the size of the bending radii to be produced. This means a considerable amount of space and investment.
  • the invention is therefore based on the object of specifying a facing shell system that overcomes the disadvantages of the prior art, e.g. the stretched or compressed material, the resulting problems with the visible surfaces, the limited radii that can be achieved and the labor-intensive and personnel-dependent process. Furthermore, a facing shell system is to be specified that can be produced with greater reproducibility and greater process reliability, particularly with regard to dimensional accuracy. Furthermore, the object of the invention is to specify a facing shell system that can be provided within shorter delivery times.
  • An attachment shell system for a device for closing a wall opening of a building, in particular for an openable or non-openable window or for a door, has at least a first, in particular along a longitudinal direction L at least in sections curved or angular, in particular right-angled or acute-angled, first cladding profile, which is designed and set up alone or together with further cladding profiles for cladding at least one frame section of a frame of the device, the first cladding profile having an inside facing the frame section in the intended installed state and has an outside facing away from the frame section when installed as intended.
  • the facing shell system is further developed in such a way that the first cladding profile is produced by an additive manufacturing process or at least all non-flat boundary surfaces of the inside are produced using a machining manufacturing process, in particular by milling, from a blank, in particular a plate- or cuboid-shaped semi-finished blank .
  • the post-processing effort is reduced enormously. Warping, especially on the inside of the curved profile, no longer occurs and therefore does not need to be sanded down. Thanks to the homogeneous, stress-free material structure, an attractive appearance can be created with manageable effort during the subsequent powder coating of the surface. Furthermore, it should be emphasized that the material weakening that occurs due to the bending of the profile, which can be observed in particular on the radial outside of the curved profile, is not present in an facing shell system according to the present invention, which is why the resulting disadvantages with regard to the appearance and longevity of the cladding profile does not matter.
  • Another advantage of the facing shell system according to the invention is that by using machining or additively manufactured cladding profiles, components of the same dimensions can be installed to a large extent. Even experienced production personnel are not able to bend identical curved profiles with tight tolerances, especially with larger profile elements, because despite the same conditions they are always hand-made individual pieces. This deficit can be overcome through the possibility of fully automating the molding process.
  • the manufacturer of the facing shell system according to the invention has the opportunity to offer its customers a wider range of possible design variants. Since minimum bending radii no longer have to be taken into account, even narrow curves can be easily achieved. Even more complicated profiles, such as those with a series of different radii, do not pose a challenge during production, as they can be reliably produced with consistent precision and dimensional accuracy.
  • the facing shell system according to the invention is suitable not only for the use of cladding profiles that are curved at least in sections along a longitudinal direction, but also for cladding profiles that run at an angle, in particular at right angles or at an acute angle.
  • cladding profiles which were produced using a metal-cutting manufacturing process or an additive manufacturing process, mitres in the facing shell system can be completely avoided. Instead, it is possible to make all transition areas between two adjacent cladding profiles blunt. In the case of a weld seam to connect the two cladding profiles, their length can be minimized, which reduces the manual effort on the one hand and the possible temperature input on the other.
  • At least one non-planar boundary surface of the outside is/are produced by a machining manufacturing process, in particular by milling, or by laser cutting or by water jet cutting or by a combination of these manufacturing processes.
  • At least one flat boundary surface of the outside is an unprocessed outer surface of the blank, with the flat boundary surface of the outside being in particular a primary visible surface.
  • a reduction in the number of surfaces to be processed can be achieved if, for example, at least one flat boundary surface of the outside is formed on the outside by an unprocessed outer surface of the blank.
  • an unprocessed outer surface can, for example, be a primary visible surface, which is permanently visible, for example, when the facing shell system is installed as intended.
  • an unprocessed outer surface can also be a secondary visible surface, which is at least temporarily covered when the facing shell system is installed as intended or may have a subordinate visibility for other reasons.
  • the first cladding profile has at least one fastening device, in particular a clip device or a rotary holder for fastening the first cladding profile to the device.
  • a fastening device in particular a clip device or a rotary holder
  • the fastening device can be standardized elements that are designed for the connection of facing shell systems or cladding profiles to the sash frame or to the stick frame.
  • Mechanical connectors represent an alternative to the weld seam. If the transition area between two adjacent cladding profiles is made blunt, as described above, the effort involved in installing the facing shell system can be reduced by using mechanical connectors.
  • the invention also makes it possible for the first time to use sensitive surface coatings, such as the anodizing process, without visually affecting the coated surface.
  • sensitive surface coatings such as the anodizing process
  • the anodizing process cannot be used with satisfactory optical results due to the required heating/heating of the profile.
  • the cladding profile of the facing shell system has a groove-like recess at least in sections along its longitudinal extension direction, which serves in particular to accommodate one or more fastening devices, mechanical connectors or sealing profiles.
  • the depth added by the cladding profile can be reduced and the entire device thus giving it a slimmer appearance.
  • the at least one fastening device and/or the at least one mechanical connector are arranged in the at least one recess.
  • the fastening of the at least one fastening device and/or the at least one mechanical connector can be carried out either by means of a detachable joining method, such as screws or clamps, or by means of a non-detachable joining method, such as gluing or welding. In any case, this ensures that there is a secure connection or connection of the first cladding profile to the device or an adjacent cladding profile.
  • the manufacturing method of the first cladding profile also enables the integral formation of these components with the first cladding profile.
  • the prerequisite for this is that the corresponding requirements in terms of stability and flexibility can be achieved with the material used.
  • Both the CNC milling machine and the 3D printer are capable of producing components with the necessary precision.
  • adjacent cladding profiles are connected to one another, as already indicated above. This can be done either by means of mechanical connectors, which are particularly useful when there is a blunt transition area, or by a thermal joining process, in particular by welding, which has advantages in transition areas with a miter. Basically, the connection of adjacent cladding profiles serves to create an attractive appearance and to seal against the penetration of moisture, for example, into the space between the facing shell system and the sash frame.
  • At least one cladding profile of the facing shell system according to the invention is made from a metal, for example aluminum or an aluminum alloy, or from plastic, for example a polyamide or from a surface-coated material.
  • a metal for example aluminum or an aluminum alloy
  • plastic for example a polyamide or from a surface-coated material.
  • the first cladding profile is a partial cross-sectional profile of a complex cladding profile.
  • the latter is thus composed of the first cladding profile and at least one further partial cross-sectional profile, wherein the connection between the first cladding profile and the at least one further partial cross-sectional profile can be made by gluing, welding, screwing, clamping or another joining method.
  • the further partial cross-sectional profile can, according to an advantageous embodiment, be made of a different material than the first partial cross-sectional profile. This is particularly useful if the further partial cross-sectional profile is an extruded profile or a continuously cast profile, which runs in a straight line along its longitudinal direction. Such profiles made by the meter are cheaper to manufacture or purchase and thus enable economically advantageous production of the facing shell system.
  • the production of the first cladding profile using a machining process or an additive manufacturing process allows a free design of the outer contour, since this no longer depends on the bending contour, as is the case with the bending of extruded or continuous cast profiles.
  • the facing shell system consists of a one-piece frame, which is formed only from a first cladding profile and accordingly consists entirely of a cladding profile milled from a blank or a one-piece additively manufactured cladding profile.

  • the first cladding profile 16 is also arranged vertically at the top and has a straight middle piece and two curved end pieces, which merge into further vertical cladding profiles 18 at the separation points 40.
  • a vertically upper straight area between the separation points 40 ' can optionally be designed as a straight further cladding profile 18 in an extruded or continuously cast construction.
  • Fig. 5c shows schematically an application of the inventive facing system 10 on a so-called pointed arch window.
  • the vertically lower further cladding profile 18 is designed, for example, as an extruded profile or extruded profile with a straight longitudinal direction L.
  • Both lateral cladding profiles with arches are designed as first cladding profiles 16, which were manufactured by means of a machining or additive manufacturing process.
  • an arched course of the lateral (first) cladding profiles 16 can also be realized in a particularly simple manner, which has, for example, varying radii of curvature along its longitudinal direction L.
  • a course with a smaller radius of curvature RK1 can initially be provided, which then transitions into a course with a larger radius of curvature RK2, for example continuously or stepped.
  • Fig. 6 shows schematically the advantages of a one-piece facing shell system 10 according to the invention, which only has a single first cladding profile 16 having.
  • the schematic application case according to Figure 6 relates, for example, to a triangular window which has acute-angled courses along the longitudinal direction L. With a predetermined width B, depending on the size of the acute angle, a certain length l of a miter cut required in the prior art results. This length l, along which, for example, welding would have to be carried out in the prior art, can be avoided by, for example, a one-piece design of the facing shell system 10 according to the invention from a single first cladding profile 16. Such a one-piece first cladding profile 16 does not cause the need to weld long miters.
  • the invention provides a number of advantages.
  • the design freedom is high with regard to the sizes of the radii of curvature R1, R2, RK1, RK2 and also the combination of different radii of curvature in one component.
  • the procedure disclosed according to the invention makes it possible to produce non-rectilinear cladding profiles 16 with high dimensional accuracy in a process-reliable manner and with a short delivery time.
  • a high possible degree of automation allows delivery times to be significantly shortened compared to the state of the art and reduces the need for specialized workers.
