Definitions

  • the present invention relates generally to devices for receiving roller shutters or venetian blinds and the like.
  • roller shutter/Venetian blind boxes that are integrated into the building's outer wall above a window or door are well known. It is also known to equip such roller shutter/Venetian blind boxes with a decentralized room ventilation system that can transport air from the inside of the building through the roller shutter/Venetian blind box to the outside and vice versa.
  • the document EN 20 2020 005414 U1 shows a roller shutter/Venetian blind box according to the preamble of claim 1.
  • the present invention provides a roller shutter/venetian blind box according to the independent claim. Embodiments and variants thereof are specified in the dependent claims.
  • the invention relates to a roller shutter/Venetian blind box for accommodating a roller shutter or Venetian blind, comprising a base body which provides a roller shutter/Venetian blind space for arranging the roller shutter or Venetian blind and an air duct.
  • the roller shutter/Venetian blind box can have an insulating crescent that separates the roller shutter/Venetian blind space and the air duct.
  • the use of an insulating crescent is intended in particular for designs in which the roller shutter/Venetian blind box is used for roller shutters.
  • An insulating crescent can also be used for Venetian blinds. However, designs without an insulating crescent are also possible for Venetian blinds.
  • the base body comprises a first leg with a free end.
  • the roller shutter/venetian blind box comprises an air guide element which is arranged on an inner side of the first leg and is in fluid communication with the air duct, wherein the air guide element is designed to guide air from the air duct into the roller shutter/venetian blind space Air from the roller shutter/venetian blind area can also be directed into the air duct via the air guide element.
  • the air guiding element can be arranged detachably.
  • a force-fitting, form-fitting, clamping, locking, snap-in, screw or adhesive connection(s) or combinations thereof can be used.
  • the air guiding element can be arranged on the inner side of the first leg at a distance from the free end of the first leg.
  • the first leg tapers from its free end in the direction of the air guide element. This can be understood in particular to mean that the width of the first leg at or adjacent to the free end is greater than the width of the first leg in a region remote therefrom, preferably in the region of the air guide element.
  • the tapering of the first leg can be achieved by a corresponding design of its inner side, whereas an outer side of the first leg is designed in such a way that it does not contribute to the tapering.
  • the insulating crescent can be supported with a first end on the inside of the first leg and/or the air guide element.
  • the support can be detachable.
  • a force-fitting, form-fitting, clamping, locking, snap-on, screw or adhesive connection(s) or combinations thereof can be used to support the insulating crescent.
  • the insulation crescent can be supported with a second end on a stop formed in or on the base body.
  • the support can be detachable.
  • a force-fitting, form-fitting, clamping, locking, snap-on, screw or adhesive connection(s) or combinations thereof can be used to support the insulation crescent.
  • the stop can, for example, be formed on an inner side of the base body, which limits the roller shutter/venetian blind space.
  • the stop can be a recess in the base body.
  • the base body may have a second leg with a free end.
  • An insulating wedge may be provided which is arranged at the free end of the second leg.
  • the insulating wedge can comprise a part extending away from the free end of the second leg, which determines the size of an opening that extends between a free end of the insulating wedge and the free end of the first leg.
  • the curtain of a roller shutter or slats of a Venetian blind can be moved through this opening.
  • the opening can have a width in the range of 50-150 millimeters, preferably in the range of 70-90 millimeters or 130-150 millimeters.
  • the base body may have an inspection opening extending between the free end of the first leg and the free end of the second leg.
  • the inspection opening can have a width in the range of 180-230 millimetres
  • the roller shutter/Venetian blind box can have an installation height in the range of 300-350 millimeters, preferably in the range of 330 millimeters.
  • the roller shutter/venetian blind space can comprise a hollow cylindrical space, the cross section of which has a radius transverse to the longitudinal axis in the range of 80-110 millimeters, preferably in the range of 105 millimeters.
  • the arrangement of the roller shutter or venetian blind can have a cross section with respect to its longitudinal axis, the cutting surface of which has an inner circle radius in the range of mm.
  • a filler piece can be provided in the roller shutter/venetian blind space, which partially fills the roller shutter/venetian blind space.
  • Fig.1 shows schematically a roller shutter/venetian blind box 2 which is installed above a window 4 in an external building wall 6.
  • the roller shutter/venetian blind box 2 can also be arranged below or on any other side of the window. Furthermore, the roller shutter/venetian blind box 2 can also be used for a door or another type of wall opening in an external wall 6 of a building.
  • the roller shutter/venetian blind box 2 is integrated into the building wall 6, preferably in such a way that the outside of the roller shutter/venetian blind box 2 or the plaster and/or insulation applied to it are essentially in the same plane as the building's outer wall 6, thus creating a continuous surface.
  • the roller shutter/venetian blind box 2 can at least partially protrude outwards from the building's outer wall 6 or be attached to the outside of it.
  • roller shutter/venetian blind box 2 is cuboid-shaped with a length L and a height H as well as a Fig.2 specified width B.
  • the roller shutter/Venetian blind box 2 can be shaped so that it can be used, for example, for a window or door whose glare and/or sash is curved at the top, or for a window or door used in conjunction with an arched lintel.
  • Fig.2 shows a cross-section of the roller shutter/venetian blind box 2 along section AA of Fig.1 .
  • the embodiment in Fig.2 comprises a base body 8, an air guiding element 10, an insulating crescent 12, an air duct 14 and a roller shutter/venetian blind space 16.
  • the base body 8 is preferably manufactured using one or more materials with good thermal and preferably also acoustic insulation properties.
  • materials include, for example, EPS, XPS, NEOPOR, as well as all types of polystyrene.
  • the base body 8 comprises a first leg 18, which is formed by the part of the base body 8 which, with reference to the drawings, begins slightly above a first end 12a of the insulating crescent 12 and extends downwards from there.
  • the first leg 18 has a free end 20.
  • the free end 20 has a substantially planar end surface which extends substantially in the direction of the width B.
  • the end surface of the free end 20 extends in a direction which encloses an angle with the width B.
  • the end surface of the free end 20 can be substantially planar and extend obliquely from bottom right to top left or top right to bottom left with respect to the plane of the drawing.
  • the free end 20 can have an end surface which is curved in the plane formed by the height H and the width B.
  • the end surface can be U-shaped in order to be able to accommodate, for example, a sealing element and/or cabling or a fastening for a plaster rail which is explained in more detail below.
  • the first leg 18 has a smaller width (i.e. cross-section in the direction of width B) at its upper end as shown, i.e. the free end 20, than at its free end 20.
  • this is achieved on the inner side 22 of the first leg 18 by the inner side 22 extending from a location 22a where the first leg 18 has a first width to a location 22b where the first leg 18 has a second width that is smaller than the second width.
  • the inner side 22 is essentially flat and extends - in the cross-section shown - in a straight line between the point 22a and the point 22b.
  • the inner side 22 can be curved, for example in such a way that it is concave or convex in plan view (i.e. when looking at the inner side 22 in the direction of the width B as shown).
  • the point 22a is spaced from the free end 20, the width of the leg between the point 22a and the free end 20 being essentially constant.
  • the first leg 18 can be made more stable and/or stiffer in the area of its free end 20.
  • This variant can also make it easier to attach further components to the first leg 18 at and/or adjacent to the free end 20.
  • the location 22A is located at the free end 20. In this way, the space created by reducing the width of the first leg 18 in the direction of the air guide element 10 can be increased.
  • the outer side 24 of the first leg 18 forms part of the outer side 26 of the base body 8, which, when used as intended, forms part of the outer surface of the building wall 6. This ensures that the building wall 6 has a substantially continuous surface on the outside.
  • the air guiding element 10 is arranged on the inner side 22 of the first leg 18 at a distance from the free end of the first leg 18.
  • the air guiding element 10 can be attached there by means of a force-fitting, form-fitting, clamping, locking, snap-on, screw or adhesive connection or a combination of two or more such connections.
  • the air guiding element 10 provides a fluid connection, in particular for air, between the air duct 14 and the roller shutter/venetian blind space 16.
  • the air duct 14 can be connected to a so-called decentralized living space ventilation system (not shown), which has a fan (or other means) for conveying air from the interior of the building to the outside, e.g. to remove warmer air from the interior of the building for interior cooling and to supply colder air from the outside to the interior of the building and/or to remove colder air from the interior of the building and to supply warmer air from the outside to the interior of the building for interior heating.
  • a fan or other means for conveying air from the interior of the building to the outside, e.g. to remove warmer air from the interior of the building for interior cooling and to supply colder air from the outside to the interior of the building and/or to remove colder air from the interior of the building and to supply warmer air from the outside to the interior of the building for interior heating.
  • the fan can be used to transport air from the air duct 14 through the air guide element 10 into the roller shutter/venetian blind room 16. In this way, air can be removed from the interior of the building. Conversely, it is possible to use the fan to transport air from the roller shutter/venetian blind room 16 through the air guide element 10 into the air duct 14, allowing outside air to reach the interior of the building.
  • the air guiding element 10 is designed as a double-wall plate.
  • a double-wall plate comprises two essentially parallel plates which are connected by webs extending perpendicularly to them.
  • a double-wall plate thus provides channels which are rectangular in cross section.
  • the air guiding element 10 can have one or more channels provided in another way (which can, for example, be round in cross section).
  • the insulating crescent 12 separates the air duct 14 and the roller shutter/venetian blind space 16, preferably in such a way that a fluid connection between the air duct 14 and the roller shutter/venetian blind space 16 only exists via the air guide element 10.
  • the insulating crescent 12 interacts with the first end 12a and the inner side 22 of the first leg 18 above the air guiding element 10 and/or the air guiding element 10.
  • the first end 12a of the insulating crescent 12 can be attached to the inner side 22 of the first leg 18 above the air guiding element 10 and/or to the air guiding element 10 by means of a force-fitting, form-fitting, clamping, locking, snap-on, screw or adhesive connection or a combination of two or more such connections.
  • the first end 12a of the insulating crescent has a shoulder 12c, by means of which the insulating crescent is supported on the inner side 22 of the first leg 18 above the air guiding element 10 and on the air guiding element 10.
  • the support can be designed to be detachable.
  • the base body 8 has an inner side 28 which has a substantially circular segment-shaped cross-section and, when roller shutters are used, forms part of the boundary of the roller shutter/venetian blind space 16. At the upper end of the inner side 28 as shown, a stop 30 is formed in the base body 8.
  • the insulating crescent 12 interacts with the stop 30 formed on the inner side 28 of the base body 8.
  • the second end 12b of the insulating crescent 12 can interact with the stop 28 by means of a force-fitting, form-fitting, clamping, locking, snap-on, screw or adhesive connection or a combination of two or more such connections.
  • the insulating crescent 12 has an inner side 12d which has a substantially circular segment-shaped cross-section and forms part of the boundary of the roller shutter/venetian blind space 16.
  • the insulating crescent 12, the stop 28 and the inner side 28 of the base body 8 are shaped and/or arranged such that the inner side 12d of the insulating crescent 12 and the inner side 28 of the base body 8 form a substantially uninterrupted surface (apart from the area where the two inner sides adjoin one another), in particular such that the cross section of this surface also has a substantially circular segment-shaped cross section.
  • the insulating crescent 12 can be firmly connected to the base body 8 and, if necessary, the air guiding element 10.
  • the insulating crescent 12 in a detachable manner.
