Description

Technical field of the invention

The present invention relates generally to devices for accommodating roller shutters or venetian blinds and the like.

Background of the Invention (Prior Art)

Roller shutters / venetian blind boxes that are integrated into the outer wall of a building above a window or door are known. It is also known to provide such roller shutters/external venetian blind boxes with a decentralized room ventilation, which can transport air from inside the building through the roller shutter/external venetian blind box to the outside and vice versa.

Brief description of the invention

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.

In general, the invention relates to a roller shutter/external venetian blind box for accommodating a roller shutter or external venetian blind, comprising a base body which provides a roller shutter/external venetian blind space for arranging the roller shutter or external venetian blind and an air duct.

The roller shutter/external venetian blind box can have an insulating crescent that separates the roller shutter/external venetian blind space and the air duct. The use of an insulating sickle is intended in particular for embodiments in which the roller shutter/Raff Store box is used for roller shutters. When using external venetian blinds, an insulation crescent can also be used. In the case of external venetian blinds, however, designs without an insulating crescent are also possible.

Furthermore, the base body includes a first leg with a free end.

Furthermore, 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 connection with the air duct, the air guide element being configured to direct air from the air duct into the roller shutter/external blind space. Air from the roller shutter/external venetian blind area can also be routed into the air duct via the air guide element.

The air guiding element can be detachably arranged.

To arrange the air guiding element on the inside of the first leg, a force-fitting, form-fitting, clamping, locking, snapping, screwing, adhesive connection(s) or combinations thereof can be used.

The air guiding element can be arranged on the inside 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 in particular be understood 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 guiding element.

The tapering of the first leg can be achieved by a corresponding design of its inside, whereas an outside of the first leg is designed in such a way that it does not contribute to the tapering.

The insulating sickle can be supported with a first end on the inside of the first leg and/or can be supported on the air guiding element. The support can be detachable. For this support of the insulating sickle, a force-fitting, form-fitting, clamping, latching, snap, screw, adhesive connection(s) or combinations thereof can be used.

The insulating sickle can be supported with a second end on a stop formed in or on the base body. The support can be detachable. For this support of the insulating sickle, a force-fitting, form-fitting, clamping, latching, snap, screw, adhesive connection(s) or combinations thereof can be used.

The stop can be formed, for example, on an inside of the base body, which limits the space for the roller shutter/external venetian blind.

The stop can be a recess in the base body.

The base body can have a second leg with a free end.

An insulating wedge can be provided, which is arranged at the free end of the second leg.

The dam wedge may include a portion extending away from the free end of the second leg which determines the size of an opening formed between a free end of the Insulation wedge and the free end of the first leg extends. The curtain of a roller shutter or slats of a venetian blind can be moved through this opening. The opening may have a width in the range 50-150 millimeters, preferably in the ranges 70-90 millimeters or 130-150 millimeters.

The base body can have an inspection opening that extends 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 millimeters

The roller shutter/external 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/external venetian blind space can comprise a hollow-cylindrical space whose cross section has a radius in the range of 80-110 millimeters, preferably in the range of 105 millimeters, transversely to the longitudinal axis. The arrangement of the roller shutter or external venetian blind can have a cross-section with respect to its longitudinal axis, the cut surface of which has an inner circle radius in the range of mm.

A filler piece can be provided in the roller shutter/external venetian blind space which partially fills the roller shutter/external venetian blind space.

Description of the drawings

1 shows schematically a roller shutter / venetian blind box 2, which is installed over a window 4 in an outer wall 6 of the building.

The roller shutter/external venetian blind box 2 can also be placed 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 outer wall 6 of a building.

In the variant shown, the roller shutter/external venetian blind box 2 is integrated into the building wall 6, preferably in such a way that the outside of the roller shutter/external venetian blind box 2 or the plaster and/or insulation applied thereto are essentially in one plane with the outer wall 6 of the building lie, so there is a continuous surface. In further variants, the roller shutter/external venetian blind box 2 can at least partially protrude outwards from the outer wall 6 of the building or be attached to the outside of the latter.

In the variant shown, the roller shutter/external venetian blind box 2 is cuboid with a length L and a height H and, for example, in 2 indicated width B.

In other embodiments, the roller shutter/venetian blind box 2 can be shaped so that it can be used, for example, for a window or door whose frame and/or sash is curved at the top, or for a window or door that/ used in conjunction with an arched lintel.

2 shows a cross section of the roller shutter / outdoor blind box 2 along the section AA of 1 .

The embodiment in 2 comprises a base body 8, an air guiding element 10, an insulating sickle 12, an air duct 14 and a roller shutter/venetian blind space 16.

The base body 8 is preferably produced using one or more materials with good thermal and preferably also acoustic insulation properties. Such materials include, for example, EPS, XPS, NEOPOR, and 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, in relation to the drawings, starts slightly above a first end 12a of the insulating sickle 12 and extends downward from there.

The first leg 18 has a free end 20 . The free end 20 has a substantially planar end face extending substantially in the width B direction. In other embodiments, the end face of the free end of the 20 extends in a direction that includes an angle with the width B. For example, 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. In other embodiments, the free end 20 may have an end face that is curved in the plane defined by the height H and width B . For example, the end surface can be U-shaped in order to be able to accommodate a sealing element and/or cabling, for example, 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 the width B) at its upper end as shown, i.e. the free end 20, than at its free end 20.

Preferably, this is accomplished on the inner surface 22 of the first leg 18 by having the inner surface 22 extend 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.

In the variant shown, the inside 22 is essentially flat and extends—in the cross section shown—in a straight line between the point 22a and the point 22b.

In further embodiments, the inner side 22 can be curved, for example in such a way that it is concave or convex when viewed from above (i.e. when looking at the inner side 22 in the direction of width B according to the illustration).

Reducing the width of the first leg 18 towards the air guide element 10 increases the roller shutter/external venetian blind space 16, which facilitates the installation/removal and maintenance/revision of roller shutters/external venetian blinds.

In the illustrated embodiment, location 22a is spaced from free end 20 with the width of the leg between location 22a and free end 20 being substantially constant. In this way, 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 .

In further embodiments, the point 22A is at the free end 20. In this way, the space that is 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 preferably forms part of the outer side 26 of the base body 8, which forms part of the outer surface of the building wall 6 when used as intended. This ensures that the building wall 6 has an essentially continuous surface on the outside.

The air guiding element 10 is arranged on the inside 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, snapping, screwing 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 ventilation system (not shown) which has a fan (or other means) to convey 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 for interior heating and to supply warmer air from the outside to the interior of the building.

Air can be conveyed from the air duct 14 through the air guiding element 10 into the roller shutter/external venetian blind space 16 by means of the fan. This allows air to be removed from inside the building. Conversely, it is possible to convey air from the roller shutter/venetian blind room 16 through the air guide element 10 into the air duct 14 by means of the fan, as a result of which outside air can get into the building interior.

In the illustrated embodiments, the air guide element 10 is designed as a double web plate. As is known, a double-walled plate comprises two substantially parallel plates which are connected by webs extending perpendicularly thereto. A double-walled plate thus provides channels with a rectangular cross section. In other embodiments, the airfoil 10 may include one or more channels (e.g., round in cross-section) provided in other ways.

The insulating sickle 12 separates the air duct 14 and the roller shutter/external venetian blind space 16, preferably in such a way that a fluid connection between the air duct 14 and the roller shutter/external venetian blind space 16 only exists via the air guiding element 10.

The insulating sickle 12 interacts with the first end 12a and the inside 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 sickle 12 can be connected to the inside 22 of the first leg 18 above the air guide element 10 and/or to the air guide element 10 by means of a force-fitting, form-fitting, clamping, latching, snap, screw or adhesive connection or combination be attached by two or more such connections.

In the embodiment shown, the first end 12a of the insulating sickle has a shoulder 12c, by means of which the insulating sickle is supported on the inside 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 cross-section essentially in the shape of a segment of a circle and forms part of the boundary of the space 16 for the roller shutter/external venetian blind when roller shutters are used. A stop 30 is formed in the base body 8 at the upper end of the inner side 28 as shown.

With its second end 12b, the insulating sickle 12 interacts with the stop 30 formed on the inside 28 of the base body 8. The second end 12b of the insulating sickle 12 can interact with the stop 28 by means of a force-fitting, form-fitting, clamping, locking, snapping, screwing or adhesive connection or a combination of two or more such connections.

The insulating crescent 12 preferably has an inner side 12d which has a cross section essentially in the shape of a segment of a circle and forms part of the boundary of the roller shutter/external venetian blind space 16 .

The insulating sickle 12, the stop 28 and the inside 28 of the base body 8 are preferably shaped and/or arranged in such a way that the inside 12d of the insulating sickle 12 and the inside 28 of the base body 8 form an essentially uninterrupted surface (apart from the area where the two inner sides adjoin each other), in particular in such a way that the cross section of this surface also has a cross section that is essentially in the shape of a segment of a circle.

The insulating sickle 12 can be firmly connected to the base body 8 and optionally to the air guiding element 10 .

In further embodiments, provision is made for the insulating sickle 12 to be arranged in a detachable manner. In the embodiments shown, this can be achieved by an insulating sickle 12 made of an at least partially elastic material, which allows insulating sickle 12 to be fixed at the first end 12a by means of its shoulder 12c on the inside 22 of the first leg above the air guiding element 10 and/or the air guiding element 10 and to support the second end 12b of the insulating sickle 12 on the stop 30 of the base body 8, to latch it or the like.

The base body 8 has a second leg 32 . The second leg 32 of the base body has an inside 32a and an outside 32b, and a free end 32c.

The inner side 32a of the second leg 32 adjoins the inner side 28 of the base body and can have a step 32d.

The inner side 34 of the base body 8, i.e. the side of the base body that forms part of the inner surface of the building wall 6 when the roller shutter/external venetian blind box 2 is used as intended, includes the inner side 32b of the second leg 32. This ensures that the building wall 6 also has an essentially continuous surface on the outside.

The free end 32c of the second leg 32 may include a protruding structure 36 .

The distance on the one hand between the inner side 32a of the second leg 32 or, if the step 32d is present, the distance between the part of the inner side 32 shown below the step 32d and on the other hand the free end 20 of the first leg 18 defines an inspection opening 38.

The inspection opening 38 is an opening through which the roller shutter/external venetian blind space 16 can be accessed, e.g. to install/remove or service a roller shutter there.

3 illustrates embodiments in which a cleaning rail 40 already mentioned above and an insulating wedge 42 are present, which can be used for roller shutters when using the roller shutter/external venetian blind box 2 .

The plaster rail 40 can serve as a plaster finishing profile for plaster applied to the outside of the first leg 18 . Likewise or In addition, the cleaning rail 40 can be designed as a drip edge.

The insulating wedge 42 has a fastening area 42a, a free end 42b, an inner side 42c delimiting the roller shutter/external venetian blind space 16, and an underside 42d.

The fastening area 42a is used for the preferably detachable connection (e.g. by means of screws) of the insulating wedge 42 on the second leg 32 of the base body 8.

According to the illustration, the fastening area 42a is designed in such a way that it has surfaces which are shaped to complement the inside 32a and the free end 32c of the second leg 32 of the base body 8 .

The part of the insulating wedge 42 between the free end 42b of the insulating wedge 42 and the surface of the fastening region 42a designed to complement the inside 32a of the second leg 32 of the base body 8 has a length LD. The length LD determines the size of an outlet opening 44 of the roller shutter/external venetian blind box 2. The outlet opening 44 extends between the free end 20 of the first leg 18 of the base body 8 and the free end 44b of the insulating wedge 42. The outlet opening 44 is the Opening through which a roller shutter can be lowered and pulled up.

The inner side 42c of the insulating wedge 42 has a cross section in the shape of a segment of a circle. Preferably, the cross-sections in the shape of a segment of a circle of the inside 12d of the insulating crescent 12, the inside 28 of the base body 8 and the inside 42c of the insulating wedge are segments of a circle with a common center point M center M is located.

4 11 illustrates embodiments that also use a plaster rail 40 and an insulating wedge 42, the insulating wedge 42 being provided here for external venetian blinds when using the roller shutter/external venetian blind box 2. Apart from this difference, the above explanations apply 3 for the 4 accordingly, unless expressly stated otherwise.

The outlet opening 44 of 4 is the opening through which a venetian blind can be lowered and pulled up.

As can be seen from a comparison of the outlet opening 44 of 3 and the outlet port 44 of FIG 4 results, the outlet opening 44 of 3 of less than that of 4 . This is achieved in that the insulating wedge 42 of 4 has a shorter length LD.

This takes into account the construction and functionality of external venetian blinds, the slats of which require less space when lowered and raised in the direction of width B than a roller shutter bang.

As in 4 Illustrated, a filler piece 46 can be provided when using the roller shutter/external venetian blind box 2 for external venetian blinds. The filler piece 46 can fill that part of the roller shutter/external venetian blind space 16 that is not required for external venetian blinds.

The present invention may further have the following features and advantages.

The air guiding element can have a length in the range from 30 to 90, preferably 60 millimeters. An air guiding element can thus be used that is significantly shorter than previously known air guiding elements. This reduces "draft losses" as air is forced through the airfoil.

The height H of the roller shutter/external venetian blind box, also known as the installation height, can be in the range from 300 to 350, preferably 330 millimeters. This makes it possible to provide roller shutters/external venetian blind boxes with installation heights that can simplify the integration of a roller shutter/external venetian blind box into a given brickwork grid (e.g. standard grid). Furthermore, the use of door and window frames with standard dimensions is supported.

The width B of the roller shutter/external venetian blind box, also known as the installation width, can range from 250 to 490 millimeters. By matching the installation width of the roller shutter/external venetian blind box and the wall thickness, the roller shutter/external venetian blind box can be installed flush on the inside and outside in the outer wall of the building.

At the in 5 A brick case 48 is used for the base body 8, which variant shown has a substantially U-shaped cross-section with respect to the longitudinal axis L transversely to the longitudinal axis. Figuratively speaking, brick box 48 can be described as a "housing".

In the brick box 48 filling material 50 is arranged. The filling material 50 can include, for example, EPS, XPS, NEOPOR, as well as all types of polystyrene, as well as mixtures or combinations of two or more such materials.

The filling material 50 is designed in such a way that, viewed together, the brick box 48 and the filling material 50 have a cross section transverse to the longitudinal axis that corresponds to the cross section of the base body 2 corresponds, at least is comparable with this one with regard to the features that have been described as being usable in the invention. Therefore, unless otherwise stated below, reference is made to the above statements, which also apply here without repetition.

In the variant of 5 the first leg 18 of the base body 8 is provided by the left leg of the brick case 48 according to the illustration. The second leg 32 of the base body 8 is provided by the right leg of the brick case 48 and the filling material arranged there.

The stop 30 of the base body 8 is formed in the filling material 50 .

The base body 8 comprising the brick box 48 and the filling material 50 can also, as explained above, be used with an insulating wedge 42 which allows the accommodation and use of a roller shutter or a venetian blind. For illustration, on 5 referenced, which referred to the use of the brick box 48 and the filling material 50 comprehensive base body 8 with an insulating wedge 42 for shutters. The above statements regarding 3 apply here accordingly. Also for the above statements regarding 4 apply here accordingly if the base body 8 comprising the brick box 48 and the filling material 50 is used with an insulating wedge 42 for external venetian blinds.
