[0078] 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.

[0079] 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 as well as a first chamber system module 500 and a second chamber system module 600.

[0080] Fig. 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 not visible) 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.

[0081] Sections 110 and 120 can - as in Fig. 2a shown - be designed as separate components that are firmly connected to each other. Alternatively, however, the sections 110 and 120 can also be sections of a single structural component. Furthermore, the sections 110 and 120 can be designed as solid material as shown. Alternatively, one or both sections - as in Fig. 2b shown - be designed as a hollow construction. 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.

[0082] 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 referred to as the width of the support structure or the roller shutter / venetian blind box, 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. In addition, the right side of the support structure in the direction of the dashed line TT is referred to 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.

[0083] 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, the right side as shown being the outer side 132, the left side as shown (in Fig. 2d not visible) is referred to as the inner side 134. The third section can - as in Fig. 2d shown - be designed as a separate component. Alternatively, the third section 130 can be designed with the second section 120 as a structural 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 (ie its extension in the direction of the dashed line HH from Fig. 2c ), can - as in Fig. 2d shown - 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. 2d The third section 130, which is shown as being constructed in solid material, can also be constructed in hollow construction, just like sections 110 and 120.

[0084] Fig. 2e shows the support structure 100 including the third section 130 from Fig. 2d and a lateral end piece 140a mounted on the left side of the support structure 100. Fig. 2f shows the support structure 100 including the third section 130 from 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 as hollow sections, just like sections 110, 120, and 130.

[0085] 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.

[0086] 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.

[0087] 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 as the height, and the extension in the direction of the dashed line TT 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 shown, correspond; in other embodiments this may be different.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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, making 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 action of tensile and / or compressive forces. Cooling and drying the molded part increases the rigidity of the lignin, which was temporarily reduced by heating, so 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.

[0092] In other embodiments, the molded part 210 is not produced by forming processes, but by separating processes such as sawing, planing, milling or drilling.

[0093] 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.

[0094] 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.

[0095] Fig. 4b shows a perspective view of the support structure 100 together with a first molded part module 200, which as in Fig. 4a is arranged, 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 - e.g. if the sections 110 and 120 are designed as separate components - further improve their connection. The molded part modules 200 and 300 can have a distance along the inner side 114 of the first section in the height direction d 1.

[0096] 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 arranged and can be arranged along the inside 114 of the first section in the height direction a distance d 1. 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 along the inner side 124 of the second section in the depth direction d 2.

[0097] 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 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 each other. The extension of the individual chamber elements in the depth direction can - as shown in Fig. 5a shown - be the same for all chamber elements. In other embodiments - such as in Fig. 1a and 1bAs shown, 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.

[0098] 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 in 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 shown - be the same for all chamber elements. In other embodiments - such as in Fig. 1a and 1b As shown, 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.

[0099] 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.

[0100] 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 / cattail (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).

[0101] All versions apply to roller shutter and venetian blind boxes, which are designed as new construction, add-on or front-mounted boxes.

[0102] Fig. 6 shows a perspective view of a wall duct element 1100, which can be provided for a ventilation device 1000, for example in the form of a decentralized room ventilation system. The wall duct element 1100 can be designed as a cuboid element 1100.

[0103] The wall penetration element 1100 has a first side 1101 and a second side 1102. In the installed state, the first side 1101 will typically represent the rear side, facing the interior of the building, and the second side 1102 will typically represent the front side, facing the exterior of the building or outwards.

[0104] The wall penetration element 1100 has a third side 1103 and a fourth side 1104. When installed, the third side 1103 typically represents the underside, facing downwards or "towards the ground," and the fourth side 1104 represents the top, facing upwards or "towards the sky."

[0105] The wall penetration element 1100 has a fifth side 1105 and a sixth side 1106. In the installed state, when viewed from the outside of a building wall on which the wall penetration element 1100 is arranged, the fifth side 1105 will typically represent the right side and the sixth side 1106 the left side.

[0106] According to the illustrations, the wall feedthrough element 1100 is shown as a cuboid element by way of example. In such an embodiment, the first, second, third, fourth, fifth, and sixth sides of the wall feedthrough element 1100 essentially correspond to the surfaces of the cuboid. That is, the opposite sides are essentially parallel to each other, whereas adjacent sides are essentially perpendicular to each other.

[0107] However, embodiments are also provided in which opposing surfaces are not substantially parallel to one another and / or adjacent surfaces are not perpendicular to one another. In such embodiments, the wall feedthrough element 1100 may, for example, have the shape of a parallelepiped, or more generally, the shape of a polyhedron with six sides.

[0108] The first and second sides 1101 and 1102 are parallel to each other as opposite sides of the wall feedthrough element 1100. In some embodiments, the sides 1101 and 1102 may also be only approximately parallel. In some embodiments, the sides 1101 and 1102 may have a surface structure. The perpendicular to the first side 1101 of the wall feedthrough element 1100 defines a depth direction of the wall feedthrough element 1100, which is represented in Fig. 8a by a dashed line and designated TQ - TQ ("depth direction of the cuboid element").

[0109] Sides 1103 and 1104 are parallel to each other as opposite sides of the wall feedthrough element 1100. In some embodiments, sides 1103 and 1104 may also be only approximately parallel. In some embodiments, sides 1103 and 1104 may have a surface structure. The perpendicular to the third side 1103 of the wall feedthrough element 1100 defines a height direction of the wall feedthrough element 1100, which is represented in Fig. 8a by a dashed line and labeled HQ - HQ ("height direction of the cuboid element").

[0110] Sides 1103 and 1104, as opposite sides of the wall feedthrough element 1100, are perpendicular to the likewise opposite sides 1101 and 1102 of the wall feedthrough element 1100. This direction, which is simultaneously perpendicular to the depth direction TQ - TQ and the height direction HQ - HQ, defines a width direction of the wall feedthrough element 1100, which is denoted by BQ - BQ ("width direction of the cuboid element") in Fig. 8a, represented by a dashed line.

[0111] The side of the wall feedthrough element 1100 perpendicular to the width direction BQ - BQ, the distance of which from the passage 1110 is smaller than from the support recess 1120, is referred to as the side of the wall feedthrough element 1100 near the passage and is, as shown in Fig. 8a, the right-hand side 1105 of the wall feedthrough element 1100. The side of the wall feedthrough element 1100 opposite the side near the passage is referred to as the side of the wall feedthrough element 1100 far from the passage and is, as shown in Fig. 8a, the left-hand side 1106 (not visible in Fig. 8a) of the wall feedthrough element 1100.

[0112] The wall duct element 1100 has an air passage 1110 (hereinafter also referred to as passage) which extends from the rear, first side 1101 shown in the illustration to the front, second side 1102 shown in the illustration. The air passage 1110 is designed to be able to guide air through the wall duct element 1100, in particular to create air from the interior of a building to the outside and vice versa. The air passage 1110 has an inlet / outlet opening 1110a on the first side 1101 and an inlet / outlet opening 1110b on the second side 1102. Whether the openings 1110a and 1110b serve as inlets or outlets depends on whether air is guided through the air passage 1110 from the second side 1101 to the first side 1102 or vice versa.Generally, the wall duct element 1100 will be arranged such that the inlet / outlet opening 1110a serves to receive air to be exhausted from the interior of the building or to introduce outside air into the interior of the building. Based on this, the inlet / outlet opening 1110b would then serve to exhaust air from the interior of the building to the outside or to convey outside air to the interior of the building.

[0113] The wall feedthrough element 1100 further comprises a support recess 1120, which extends between the third and fourth sides 1103 and 1104 and is open to the first side 1101. A cross section of such a support recess 1120 is shown in Fig. 6a illustrated.

[0114] The support recess 1120 may also be open towards one of the fifth or sixth sides 1105 or 1106. The cross section of such a support recess 1120 is shown in Fig. 6b illustrates where the support recess 1120 is also open towards the sixth side 1106. In further such embodiments, the support recess 1120 is open towards the fifth side 1105, i.e., is arranged on another side of the wall feedthrough element 1100. Such a variant is also shown in Fig. 11-14 illustrated.

[0115] The cross section of the support recess 1120 can be in the height direction, as in Fig. 6 , 6a und 6b shown, be rectangular or, as in Fig. 6c und 6d As illustrated by way of example, it may be semicircular, quarter-circular, or otherwise curved. The cross-sectional shape of the support recess 1120 is preferably shaped such that it can accommodate a portion of the load-bearing structure, as explained below. The latter can be positively or non-positively connected.

[0116] The support recess 1120 serves to arrange the wall duct element 1100 on a load-bearing structure 900. The load-bearing structure 900 can be part of a wall constructed using a timber frame, timber stud, timber skeleton, timber frame, timber panel, or timber module construction, such as a post. Likewise, the load-bearing structure 900 can be part of a steel skeleton or reinforced concrete skeleton construction, such as a steel beam. The load-bearing structure 900 can be part of a wall constructed using a solid construction method. As shown in Fig. 6e As illustrated, the wall penetration element 1100 can be arranged, for example, in a brick wall between an upper row of bricks ZR1 and a lower row of bricks ZR2. In such cases, the support recess 1120 can be at least partially filled, for example, with a filler FS (e.g., concrete, wood), which can, for example, ensure force dissipation from the upper row of bricks ZR1 to the lower row of bricks ZR2. Such a filler is also understood as a load-bearing structure 900.

[0117] The wall duct element 1100 can, as in Fig. 7 illustrated, comprise an air duct recess 1130 on the second side 1102. The air duct recess 1130 is designed such that the inlet / outlet opening 1110b of the air passage 1110 opens into the air duct recess 1130, this is shown in Fig. 7a indicated by the dashed circle ÖB. In this way, air, for example air introduced from outside into the air duct recess 1130, can pass from the air duct recess 1130 into the air passage 1110 and from there into the building interior, and / or from the building interior through the air passage 1110 into the air duct recess 1130 and from there, for example, to the outside.

[0118] The air duct recess 1130 is designed to accommodate an air duct. In principle, the air duct recess 1130 can be designed to accommodate an air duct in a form-fitting and / or force-fitting manner. For this purpose, the air duct recess 1130 can be shaped to complement the areas of a ventilation duct that are to be accommodated there.

[0119] In the case of a flat duct, the air duct recess 1130 can have a cross-section transverse to the depth direction as in Fig. 7a illustrated.; ie a substantially rectangular cross-section. Such an air duct recess 1130 can, for example, accommodate a Fig. 7b illustrated flat duct 1200. The flat duct 1200 has an inlet / outlet opening 1202 and an inlet / outlet opening 1204. The inlet / outlet opening 1202 is provided for fluid connection with the inlet / outlet opening 1110b of the air passage 1110 in order to be able to bring air from the air passage 1110 into the flat duct 1200 and vice versa. An optional pipe RO can be connected to the inlet / outlet opening 1202, which can be at least partially introduced into the air passage 1110. The inlet / outlet opening 1204 of the flat duct 1200 serves to bring air from the air duct 1200 to the outside (e.g. ambient air) or to a connected air duct and vice versa. This in Fig. 7c illustrated by the double arrow LFR.

[0120] The air duct recess 1130 can also be designed to accommodate an air duct with a variable cross-section. Such an air duct 1210 is shown in Fig. 7d und 7e illustrated. Fig. 7d shows an example cross-section and Fig. 7e an exemplary view of the side of the air duct 1210, where an inlet / outlet opening 1202 is provided

[0121] The exemplary air duct 1210 shown therein has a wider duct section 1210a, which can be described as cuboid-shaped, as well as an adjoining duct section 1210b with a tapered cross-section, followed by a duct section 1210c in the form of a flat duct. The complementary design of an air duct recess 1130 is shown in Fig. 7f illustrated.

[0122] The air duct 1210 has an inlet / outlet opening 1202 and an inlet / outlet opening 1204. The inlet / outlet opening 1202 is provided for fluid connection with the inlet / outlet opening 1110b of the air passage 1110 in order to be able to bring air from the air passage 1110 into the air duct 1210 and vice versa. An optional pipe RO can be connected to the inlet / outlet opening 1202 and can be at least partially introduced into the air passage 1110. The inlet / outlet opening 1204 of the air duct 1210 serves to bring air from the air duct 1200 to the outside (e.g., ambient air) or to a connected air duct and vice versa. This Fig. 7g illustrated by the double arrow LFR. In addition to the inlet / outlet opening 1202, the air duct 1210 has a further inlet / outlet opening 1204. The inlet / outlet opening 1204 of the flat duct 1210 serves to bring air from the air duct 1210 to the outside (e.g. ambient air) or to a connected air duct and vice versa. This in Fig. 7g illustrated by the double arrow LFR.

[0123] In other words, in the above embodiments of the air duct recess 1130, it is provided that it extends along the width direction BQ - BQ toward the side 1106 of the cuboid element remote from the passage. In other embodiments, the air duct recess 1130 can extend along the width direction BQ - BQ toward the side 1106 of the wall feedthrough element 1100 close to the passage.

[0124] The shape of the air duct recess 1130 can change along the width direction BQ - BQ. As shown in Fig. 7 As shown, the recess may comprise a flat, cuboid-shaped section, which is adjoined by a triangular prism-shaped section in the direction of the side 1106 remote from the passage. In some embodiments, the triangular prism-shaped section may be omitted.

[0125] The above embodiments of the air duct recess 1130 can be used to bring air from the building interior to a window or door lintel and vice versa, or, as described below, to a downstream air duct and vice versa.

[0126] As in Fig. 8 As shown, the air duct recess 1130 can extend along the height direction HQ - HQ, for example, towards the fourth side 1104 towards the third side 1103. Fig. 8 The variant shown is, in terms of the design of the air duct recess 1130, comparable to that of Fig. 7a comparable. In other words, the air duct recess 1130 can comprise a cuboid-shaped section. However, it is also provided here to use configurations of the air duct recess 1130 considered individually, which are comparable to the Fig. 7f are comparable. In other words, a cuboid-shaped section can be followed by a section in the shape of a triangular prism.

[0127] Embodiments of the air duct recess 1130 in the sense of Fig. 8 can be used to bring air from the interior of a building to areas behind a (suspended) facade or a roof transition and vice versa.

[0128] In general, the direction of extension of the air duct recess 1130 and the direction in which the support recess 1120 extends will be substantially perpendicular to each other. In further embodiments, the direction of extension of the air duct recess 1130 and the direction in which the support recess 1120 extends may enclose any angle.

[0129] The air passage 1110 may have a circular cross-section, as illustrated in the previous drawings. As shown in Fig. 9a As shown, the air passage 1110 may have a circular cross-section with radius r D ,1 (not shown) on the first side 1101 of the wall duct element 1100 and radius r D,2 on the second side 1102 of the wall feedthrough element 1100. In some embodiments, the passage 1110 may have a circular cross-section with a radius that is partially or completely constant in the depth direction. The passage 1110 may, as in Fig. 9a shown at a distance d 2 from the side 1105 of the wall duct element 1100 close to the passage.

[0130] The passage 1110 can, as in Fig. 9b shown, a rectangular cross-section with width b D, 1 and height h D, 1 (both in Fig. 9b not shown) on the first side 1101 of the wall duct element 1100 and with width b D , 2 and height h D,2 on the second side 1102 of the wall feedthrough element 1100. In some embodiments, the passage 1110 may have a rectangular cross-section with a height and / or width that is partially or completely constant in the depth direction. The passage 1110 may, as in Fig. 9b shown at a distance d 2 from the side 1105 of the wall duct element 1100 close to the passage.

[0131] The support recess 1120 can, as explained above, accommodate a portion of a load-bearing structure 900; for example, a vertical section 910 as shown. The support recess 1120 can, as in Fig. 9a shown, in the depth direction TQ - TQ of the cuboid element have an extension t and in the width direction BQ - BQ of the cuboid element have an extension b. The support recess 1120 can be at a distance d1 from the side 1106 of the cuboid element remote from the passage. In some embodiments, the distance d 1 be zero, as in Fig. 6b und 6d In some embodiments, the support recess 1120 may extend non-perpendicularly from the third side 1103 to the fourth side 1104 and may accommodate a sloped portion of a load-bearing structure 900, such as occurs in trusses.

[0132] Fig. 10 shows a perspective view of a modular wall duct element 1100. The wall duct element 1100 comprises - starting from the second side 1102 of the wall duct element 1100 - the modules 1107a, 1107b, ..., 1107f arranged one behind the other in the depth direction TQ -TQ. The modules 1107a, 1107b, ..., 1107f can, as in Fig. 10 As shown, the modules have different thicknesses in the depth direction TQ - TQ of the cuboid element. In some embodiments, some, several, or all modules may have the same thickness in the depth direction.

[0133] The front module 1107a shown in the illustration can be referred to as the base module, particularly if an air duct recess 1130 is formed there. The front side 1102 of the base module 1107a shown in the illustration provides the second side 1102 of the wall feedthrough element 1100.

[0134] The adjoining modules 1107b, ... can be considered sub-modules. By selecting the number and / or thickness of the sub-modules, the extension of the wall penetration element 1100 in the depth direction can be variably determined.

[0135] The support recess 1120 can be formed in one or more of the sub-modules. If the support recess 1120 is formed in only one of the sub-modules, ie, the last one in the row 1107f, the support recess 1120 can also extend only partially through this.

[0136] In further embodiments, a combination of a wall air duct element 1100 and a roller shutter / venetian blind box 800 is provided to provide a ventilation arrangement 1000. In principle, any roller shutter / venetian blind box can be used here because, as explained below, it is not modified per se, but rather is given a structure to accommodate an air duct. In particular, however, it is provided to use one of the roller shutter / venetian blind boxes described above with reference to Fig. 1 bis 5 Advantageous embodiments result from the use of a modular roller shutter / venetian blind box as described above and a wall air duct element of a similarly modular design. This allows for a selectively adjustable extension in the depth direction.

[0137] In the following explanations, reference is made to a ventilation arrangement 1000 which, as in Fig. 11 and 12 illustrated, is arranged in a timber-frame wall structure. The relevant statements apply accordingly to any wall structure where there is load transfer in the 900 structure.

[0138] As in Fig. 11 Illustrates the wall structure there, with its timber frame construction, with vertically aligned uprights 900 and horizontally aligned crossbeams 902. A roller shutter / venetian blind box 800 (hereinafter referred to as "box") is arranged between two adjacent uprights 900a and 900b and is typically attached to them. The fact that the box 800 extends across the entire distance between the two adjacent uprights 900 and is adjacent to them can be explained, for example, by the fact that there is a window below the box 800 that extends across the entire width between the uprights.

[0139] As shown, the wall air duct element 1100 is narrower in the width direction, so that it does not bridge the entire distance between the two adjacent uprights 900b and 900c between which it is arranged. This is based on the approach of dimensioning the wall air duct element 1100 at least just enough to accommodate the air passage 1110. In this way, the remaining space between the wall air duct element 1100 and the upright 910, to which the wall air duct element 1100 does not reach, can be used for other purposes. In further embodiments, however, wall air duct elements 1100 are provided that extend completely between two adjacent uprights.

[0140] As illustrated, the wall air duct element 1100 is arranged such that a section 910 of the upright 900b is received in the support recess 1120. There, the wall air duct element 1100 can be connected to the upright 900b. In the variant shown here, a support recess 1120 in the sense of Fig. 6a und 6d , i.e., one that is open to the first side 1101 and the sixth side 1106. The support recess 1120 allows the upright 900b to be left unchanged and its load-bearing function not to be impaired. Furthermore, the space in front of the upright 900b can be used as shown. This space is in Fig. 11 denoted by R.

[0141] This space can be used, for example, to arrange an air duct recess 1130; at least parts of it. This is in Fig. 12 illustrates where an air duct recess 1130 also extends into the space R. Furthermore, Fig. 12 an air duct 1300 which is arranged on the front side VS (described above with reference to Fig. 1 bis 5 also designated 132) of the box 800.

[0142] The ventilation duct 1300 has an inlet / outlet opening 1302 and an inlet / outlet opening 1304.

[0143] The inlet / outlet opening 1302 is provided for fluid connection with the inlet / outlet opening 1204 of an air duct 1200 / 1210 arranged in the air duct recess 1130, and serves to supply air from this to the ventilation duct 1300 and vice versa.

[0144] The inlet / outlet opening 1304 serves to bring air from the air duct 1300 to the outside (e.g. ambient air) or to a subsequent air duct and vice versa.

[0145] Fig. 13 illustrates a cross-sectional view of the arrangement of Fig. 12 perpendicular to the vertical direction. In addition, Fig. 13 Also shown is an air duct arranged in the air duct recess 1130; here, for example, the air duct 1210 explained above. In the area designated V, the inlet / outlet opening 1302 of the air duct 1300 and the inlet / outlet opening 1204 of the air duct 1210 are connected to one another; preferably in a fluid-tight manner, so that no air can escape there. This arrangement allows, as indicated by the arrow LFR, air to be conveyed through the air passage 1120, the air duct 1210, and the air duct 1300, and vice versa.

[0146] To cover the air duct 1300, a cover AD can be provided on the front side VS of the box 800. This can be made, for example, using wood. The cover AD can have an air duct recess 1400, which can be shaped to complement the shape of the air duct 1330 being used. Fig. 14 shows such an exemplary air duct recess 1400, which is used to accommodate the air duct 1300 of Fig. 12 and 13 is suitable.
