[0018] Fig. 1a shows a perspective view of a modular roller shutter box comprising a support structure 100, a first molded part module 200, a second molded part module 300, a third molded part module 400 as well as a first chamber system module 500 and a second chamber system module 600.

[0019] Fig. 1b shows a perspective view of a modular Venetian blind box comprising a support structure 100, a first interior module 200, a second interior module 300, a first chamber system module 500, and a second chamber system module 600.

[0020] Fig. Figure 2a shows a perspective view of a support structure 100 of a modular roller shutter / venetian blind box. The support structure shown comprises a first, vertically arranged section 110 as shown, and a second, horizontally arranged section 120, which is substantially perpendicular to the first section 110. The left side of the first section (in Fig. 2a) is referred to as the outer side 112, the right side of the first section 110 is referred to as the inner side 114. The upper side of the second section 120 is referred to as the outer side 122, the lower side of the second section 120 (in Fig. 2a not visible) is referred to as inner side 124.

[0021] Sections 110 and 120 can - as in Fig. 2a - be designed as separate components that are firmly connected to each other. Alternatively, however, sections 110 and 120 can also be sections of a single structural component. Furthermore, sections 110 and 120 can be designed as solid material, as shown. Alternatively, one or both sections - as in Fig. 2b. The hollow construction of the support structure can allow for a better connection due to the larger contact area between the two components, for example, if sections 110 and 120 are designed as separate components. In addition, improved thermal and / or acoustic insulation of the support structure can be achieved by filling the cavity 116 of section 110 and / or the cavity 126 of section 120 with a material with low thermal and / or acoustic conductivity.

[0022] Fig. 2c shows the support structure 100 from Fig. 2a, where the extension of the support structure 100 in the direction of the dashed line BB is designated as the width of the support structure or the roller shutter / venetian blind box, the extension in the direction of the dashed line HH as the height, and the extension in the direction of the dashed line TT as the depth. In addition, the right side of the support structure in the direction of the dashed line TT is designated as the front side of the support structure or the roller shutter / venetian blind box, the left side (in Fig. 2c not visible) is referred to as the back side. Furthermore, the side of the support structure facing the viewer in the direction of the dashed line BB is referred to as the left side of the support structure or the roller shutter / venetian blind box, the side facing away from the viewer (in Fig. 2c not visible) in the direction of the dashed line BB is referred to as the right side.

[0023] Fig. 2d shows the support structure 100 from Fig. 2a together with a third section 130 arranged on the front side of the support structure 100, wherein the right side as shown is designated as the outer side 132, the left side as shown (in Fig. 2d not visible) is referred to as inner side 134. The third section can - as in Fig. 2d - be designed as a separate component. Alternatively, the third section 130 can be designed with the second section 120 as a structurally integrated component. The third section 130 can have the function of a panel. The third section 130 can have a supporting function. The third section 130 can have the function of an air-guiding element. The height of the third section 130 (i.e. its extension in the direction of the dashed line HH from Fig. 2c), can - as in Fig. 2d - be less than the height of the support structure 100. In other embodiments, the third section 130 may be the same length or longer in the vertical direction than the first section 110. The Fig. The third section 130, which is shown in Figure 2d as being constructed in solid material, can also be constructed in hollow construction, just like sections 110 and 120.

[0024] Fig. 2e shows the support structure 100 including the third section 130 of Fig. 2d and a lateral end piece 140a attached to the left side of the support structure 100. Fig. 2f shows the support structure 100 including the third section 130 of Fig. 2d and a lateral end piece 140b mounted on the right side of the support structure. The lateral end pieces 140a and 140b shown as solid construction can also be constructed in a hollow construction, just like sections 110, 120, and 130.

[0025] The support structure 100, the third section 130, and the lateral end pieces 140a and 140b can be combined as desired. The sections and elements designated by reference numerals 110, 120, 130, 140a, and 140b can be implemented in any combination using solid material construction and / or hollow construction. Furthermore, any combination of two or more of the sections and elements designated by reference numerals 110, 120, 130, 140a, and 140b can be implemented as a single structural component.

[0026] Fig. 3a shows a perspective view of the first molded part module 200. This comprises a curved molded part 210 and a base structure 220, which are firmly connected to one another. The base structure 220, in turn, comprises a left section 222 (as shown), a right section 224 (as shown), and a lower section 226 (as shown). The sections 222, 224, and 226, together with the curved molded part 210, form a cavity 230.

[0027] Fig. 3b shows the first molded part module 200 from Fig. 3a, wherein the extension of the first molded part module 200 in the direction of the dashed line BB is referred to as the width of the molded part module, the extension in the direction of the dashed line HH is referred to as the height, and the extension in the direction of the dashed line TT is referred to as the depth. The width, height, and depth directions with respect to the first molded part module 200 can be aligned with the width, height, and depth directions with respect to the support structure 100 or the roller shutter / venetian blind box, as shown in Fig. 2c; this may be different in other embodiments.

[0028] Fig. 3c shows a perspective view of the curved molded part 210 from Fig. 2a. The curvature r of the molded part is adapted to the curvature of a roller shutter curtain in the fully retracted state, so that the distance between the molded part 210 and the roller shutter curtain is as small as possible in the fully retracted state. A shape of the molded part 210 that is optimally adapted to the shape of the roller shutter curtain in the fully retracted state can have various advantages over roller shutter boxes whose interior is composed of several, exclusively non-curved sections: The improved space utilization when using an optimally curved molded part can enable the introduction of more insulating material into the cavity 230, thereby achieving improved thermal insulation. Minimizing the air-filled space between the molded part 210 and the roller shutter curtain can, additionally or alternatively, ensure improved sound absorption. The curvature of the molded part 210 can ensure improved air circulation.

[0029] In some embodiments, the molded part 210 is made from wood fiberboard, which in turn is made from lignocellulose fibers. Lignocellulose forms the cell walls of woody plant parts and, as a renewable raw material, can be obtained from, for example, wood, wood waste, sawmill by-products, but also from wood-fiber-containing plants such as straw, reed, flax, or rapeseed.

[0030] At the molecular level, lignocellulose consists essentially of cellulose and hemicelluloses, each of which is characterized by high tensile strength due to its fibrous structure, as well as lignin, which, as a natural polymer with thermoplastic properties, exhibits high stiffness and compressive strength under normal environmental conditions and acts as a natural adhesive between the cellulose fibers.

[0031] To impart curvature to a molded part 210 made from a wood fiberboard, the part is first heated under the influence of steam. Due to the thermoplastic properties of lignin, the heating reduces its rigidity, rendering the previously dimensionally stable wood fiberboard deformable. Using manual or mechanical forming processes, the deformed wood fiberboard is drawn, bent, pressed, and / or pressed into the desired shape by the application of tensile and / or compressive forces. Cooling and drying the molded part increases the rigidity of the lignin, which was temporarily reduced by heating, thus ensuring that the molded part retains its imparted curvature. To avoid undesired deformation of the molded part during the drying process, suitable devices for maintaining its shape are required.

[0032] In other embodiments, the molded part 210 is not produced by forming processes, but by separating processes such as sawing, planing, milling or drilling.

[0033] Fig. 3d shows a perspective view of the base structure 220 from Fig. 3a. In addition to the sections 222, 224, and 226, the base structure 220 can also have further elements such as a support structure 240 oriented in the width direction and / or a support structure 250 oriented in the depth direction, which in turn can comprise one or more width support elements 242, 244 and / or one or more depth support elements 252, 254. If the support structures 240 and / or 250 are present, the cavity 230 can be divided into several smaller cavities. In a wider first molded part module 200, the support structures 240 and / or 250 can contribute to greater dimensional stability of the molded part module and to an improved connection between the molded part 210 and the base structure 220.

[0034] Fig. 4a shows a perspective view of the support structure 100 together with a first molded part module 200, which is arranged on the inner side 114 of the first section 110, preferably flush with its lower edge.

[0035] Fig. Figure 4b shows a perspective view of the support structure 100 together with a first molded part module 200, which as in Fig. 4a, as well as a second molded part module 300, which, compared to the first molded part module 200, has been rotated by 180° about an axis running in the depth direction of the molded part module, so that it is arranged on the inner side 114 of the first section and simultaneously on the inner side 124 of the second section. Due to the arrangement of the second molded part module 300, this can further improve their connection - e.g., if the sections 110 and 120 are designed as separate components. The molded part modules 200 and 300 can have a distance d1 in the height direction along the inner side 114 of the first section.

[0036] Fig. 4c shows a perspective view of the support structure 100 including the third section 130 together with a first molded part module 200, a second molded part module 300 and additionally a third molded part module 400. The molded part modules 200 and 300 are as in Fig. 3b and can have a distance d1 along the inner side 114 of the first section in the vertical direction. The third molded part module 400 is rotated by 180° about an axis running in the width direction of the molded part module compared to the first molded part module 200, so that it is arranged on the inner side 124 of the second section 120 and simultaneously on the inner side 134 of the third section 130. The molded part modules 300 and 400 can have a distance d2 along the inner side 124 of the second section in the depth direction.

[0037] Fig. 5a shows a perspective view of the support structure 100 together with a vertically arranged chamber system module 500. The chamber system module 500 can consist of one or more chamber elements 510, 520, which, as shown, are arranged one behind the other in the depth direction flush with the rear side 112 of the support structure 100 and are firmly connected to the latter and to one another. The extension of the individual chamber elements in the depth direction can - as shown in Fig. 5a - be the same for all chamber elements. In other embodiments - such as in Fig. 1a and Fig. 1b, the individual chamber elements can have different depth dimensions in pairs. Combining one or more chamber elements with different depth dimensions allows the depth dimension of the entire roller shutter / venetian blind box to be individually adapted to the respective conditions. This includes, in particular but not exclusively, adaptation to standard wall thicknesses of 220 mm, 240 mm, 250 mm, 260 mm, 280 mm, 300 mm, 365 mm, 425 mm, and 490 mm.

[0038] Fig. 5b shows a perspective view of the support structure 100 together with the chamber system module 500 consisting of two chamber elements 510 and 520, which is arranged vertically as shown. Fig. 5a and with an additional, horizontally arranged chamber system module 600. The chamber system module 6000 can consist of one or more chamber elements 610, 620, which are arranged one above the other in the vertical direction flush with the upper side 122 of the support structure 100 and are firmly connected to the latter and to each other. The extension of the individual chamber elements in the vertical direction can - as shown in Fig. 5b - be the same for all chamber elements. In other embodiments - such as in Fig. 1a and Fig. As shown in Figure 1b, the individual chamber elements can have different vertical dimensions, preferably in pairs. The combination of one or more chamber elements with different vertical dimensions allows the vertical dimension of the entire roller shutter / venetian blind box to be individually adapted to the respective conditions.

[0039] Individual, multiple, or all cavities within the molded-part modules and within the chamber elements of the chamber system modules can be fully or partially filled with insulating materials that have low thermal and / or acoustic conductivity. In addition to conventional mineral-based insulating materials such as perlite (as bulk material), mineral wool (as mats or panels), expanded clay (as bulk material), and foam glass (as bulk material or panels), insulating materials made entirely or partially from renewable raw materials can also be used.

[0040] Typical insulation materials in this context can include the following materials and material classes: sisal (as mats or panels), kenaf (as mats or panels), (stinging) nettle fibers, animal hair, mushroom mycelium (as insulation panels), cellulose-textile fiber hybrid insulation made of cellulose (waste paper) and textile fibers (old clothes), hemp (as stuffing or blown-in insulation), straw (as panels or blown-in insulation), flax (as mats or panels), sheep's wool (as mats or stuffing), wood fiber / wood shavings / wood wool (as mats, panels, stuffing, blown-in insulation or as loose-fill insulation), cellulose (as panels or blown-in insulation), coconut fiber (as mats or panels), reed / bulktail (as mats, panels, stuffing, blown-in insulation or as loose-fill insulation), seaweed (as mats, panels, stuffing, blown-in insulation or as loose-fill insulation), cork (as mats, panels, stuffing, blown-in insulation or loose-fill insulation), jute (as mats, panels, stuffing,blown-in insulation or loose-fill insulation), meadow grass cellulose insulation (as blown-in insulation or loose-fill insulation).
