Description

[0001] The invention relates to a locking device for a blackout or shading device box of a blackout or shading device, in particular a roller shutter, an awning, a Venetian blind or a blind, which is designed for installation in a building and which has a box housing with an inspection opening that can be closed with the locking device.

[0002] It is common practice to install boxes, usually roller shutter boxes, in buildings, particularly in the upper section of window openings in the building wall. Often, so-called surface-mounted boxes are used, which are permanently attached to the window frame and securely fastened to it. Roller shutter boxes typically have an access panel through which the winding shaft and the roller shutter curtain can be reached. This access panel is usually closed with a simple cover, often consisting primarily of a plastic sheet. Accessing the winding shaft, the roller shutter curtain, or, if present, the drive motor for maintenance is often problematic because the cover cannot be easily removed, especially without causing damage.Often the lid is wallpapered, painted over or plastered over, so that after the lid is removed, painting and / or plastering work is often necessary to repair the damage caused by opening it.

[0003] From DE 20 2012 100 033 U1, a surface-mounted roller shutter is known, which is preferably attached to a window or window frame before installation. The surface-mounted roller shutter can accommodate a winding shaft and a roller shutter curtain wound and unwound on it, and consists of a thermally insulating material with an opening for the roller shutter curtain. The opening is bounded by a bottom rail attached to a mounting bracket. The bottom rail and the mounting bracket are provided with interlocking toothed connections that extend as rows of teeth transverse to the winding direction of the roller shutter curtain.

[0004] If additional items such as a curtain, a pleated blind or a lamp are required in the window area, special mounting devices are usually attached to the building wall.

[0005] From Japanese patent application JP 2020 033808 A, an electric roller shutter with a retractable shutter curtain is known, which prevents water that has penetrated the roller shutter housing from coming into contact with a battery. The electric roller shutter has an electrical closure with a closure housing to form a closure curtain housing space, in which a closure curtain is housed and arranged around a winding shaft that rotates by means of energy supplied by the battery. The electric roller shutter also has a battery housing section to form a battery compartment in which the battery is housed and which is separate from the closure curtain housing space.

[0006] The object of the present invention is to simplify access to the components arranged in a blackout or shading device box of the type mentioned above and / or to provide a means of attaching objects.

[0007] The problem is solved by a closure device of the type mentioned above, characterized in that the closure device has at least one functional element which has a penetration through a wall of the closure device and has a receptacle accessible through the penetration for receiving an energy storage device, wherein at least one electrical contact element is arranged within the receptacle in such a way that an electrically conductive contact to the contact element is automatically established by inserting the energy storage device.

[0008] In accordance with the invention, it was recognized that the locking device of a blackout or shading device box, for example a roller shutter box, can advantageously be equipped with at least one additional function.

[0009] In addition to the aforementioned functional element, the locking device can also have at least one further functional element, i.e., several, in particular different, functional elements.

[0010] For example, with regard to attaching objects, this has the distinct advantage that it is not necessary to damage the building wall, the frame, or the window frame, for instance, by using screws, in order to attach the objects. Instead, it can be advantageously designed, for example, that a curtain is attached solely to the locking mechanism, so that the building wall and the window remain completely unchanged.

[0011] In particular, the invention makes it possible to replace an existing conventional locking device, which only has a cover function, with a locking device according to the invention, in order to have at least one additional function available. In particular, this allows tenants to implement an additional function in a rented apartment without having to damage the building wall or the window. After termination of the tenancy, the locking device according to the invention can be replaced again by the previous, conventional locking device.

[0012] In a particularly advantageous embodiment, the functional element comprises a fastening element designed to interact with a mating fastening element of an object to be fastened, in particular by positive locking and / or magnetic connection. The fastening element can, for example, be a snap-fit ​​element. In particular, the fastening element can be designed to be part of a snap-fit ​​connection that can be released, in particular non-destructively and / or without tools. For this purpose, it can be particularly advantageous to provide that the fastening element can be mechanically and / or magnetically coupled to a mating fastening element of the object to be fastened.

[0013] In the locking device according to the invention, the functional element has an opening through a wall of the locking device. Such an opening makes it possible to access the components arranged inside the blackout or shading device housing, such as a winding shaft, a drive motor, or a control device for the drive motor, without having to remove the entire locking device. Preferably, the locking device has a cover for closing the opening.

[0014] In the locking device according to the invention, the locking device also has a receptacle for an object, accessible through the opening. For example, the receptacle can be designed to receive an energy storage device, particularly an electrical one. The electrical energy storage device can, for example, serve to supply drive energy to a drive motor arranged inside the blackout or shading device housing.

[0015] In the locking device according to the invention, at least one electrical contact element is arranged within the receptacle such that an electrically conductive contact with the contact element is automatically established upon insertion of the energy storage device. This advantageously achieves the user only needing to insert the energy storage device, particularly in a form-fitting manner, into the receptacle, with the electrical connection being made automatically. An additional, cumbersome connection of the energy storage device by the user is thus advantageously avoided.

[0016] In a particularly advantageous embodiment, the object can be inserted into the receptacle in such a way that an outer surface of the object is flush with an outer surface of the locking device.

[0017] The additional functional element can be designed, in particular, as an electrical connector, especially a panel-mount socket or plug. Such a functional element makes it possible, for example, to couple electrical energy into the blackout or shading device box or to draw electrical energy from the blackout or shading device box, for example, from an energy storage device arranged in a receptacle of another functional element. For this purpose, for example, a plug from an external device can be inserted into the electrical connector.

[0018] In a particularly advantageous embodiment, the additional functional element is designed for the coupling of a belt guide device for a roller shutter belt, especially in a form-fitting and / or locking manner. The belt guide can, in particular, include a guide roller and / or a seal, especially a draught seal. With such a belt guide, the roller shutter belt glides smoothly through the belt opening thanks to the guide roller, which significantly reduces wear on the belt.

[0019] In a particularly advantageous embodiment, the additional functional element is designed as a cable duct. Such an embodiment has the distinct advantage that at least one cable can be concealed and protected, for example, from one end of the locking device, particularly horizontally, to the area of ​​the other end of the locking device. This is useful, for instance, for connecting a drive motor located in the housing at the other end. However, it is also possible, for example, to route a cable, particularly from a first external cable duct, concealed and protected simply through the locking device, particularly to a second external cable duct, so that no additional external cable duct needs to be installed parallel to the locking device; in particular, no additional external cable duct connecting the first and second external cable ducts is required.

[0020] The closure device, particularly in the area of ​​a cable duct, may have at least one additional cable passage through which a cable can be routed. The cable passage is preferably only slightly larger than the diameter of the cable to be routed, for example, a connection cable for a drive motor of a blackout or shading device. In particular, the cable passage may have an opening width, especially a diameter, in the range of 5 mm to 20 mm. The cable passage may be circular, but other shapes are also possible. In particular, two cable passages may be provided, so that a cable can be routed through one of the cable passages into a cable duct of the closure device and through the other cable passage out of the cable duct.

[0021] At least one cable entry point can be arranged, for example, on a front surface of the locking device. Such a design is particularly advantageous if the blackout or shading device box is installed in such a way that the front surface is flush with a building wall.

[0022] It is also possible for at least one cable entry point to be arranged on one end face, particularly a side face, of the locking device. Such a design is particularly advantageous if the blackout or shading device box is installed with an overhang, especially towards the interior of the building.

[0023] In a particularly advantageous embodiment, the locking device, especially in the area of ​​a cable passage, has a coupling element that allows an external cable duct to be attached to the locking device, in particular in a way that is detachable without damage and / or tools. In particular, the coupling element can be designed to interact with a mating coupling element of an external cable duct. The coupling element and / or the mating coupling element can, in particular, be snap-fit ​​connectors that allow a snap connection between the locking device and the external cable duct to be established, in particular without tools.

[0024] In a particularly advantageous embodiment, the cable duct has inwardly directed guide ribs. These guide ribs facilitate the sorted and orderly insertion of cables. The guide ribs can be, in particular, plate-shaped, and it can be provided that the plane of each guide rib is aligned parallel to the longitudinal direction of the cable duct and / or that the plane of each guide rib is aligned at a right angle to a mounting surface of the cable duct. In a particularly advantageous embodiment that allows for especially easy and quick cable insertion, at least two, and in particular exactly two, guide ribs are aligned parallel to each other. The guide ribs can be arranged distributed along the longitudinal direction of the cable duct.In particular, the guide ribs can advantageously be arranged in groups of at least two along the longitudinal direction of the cable duct. Preferably, the guide ribs (unlike the spring-loaded hooks mentioned below) do not have a holding function for a cable being inserted.

[0025] In an advantageous embodiment, the cable duct has inwardly directed, spring-elastic hooks, particularly for partially gripping a cable. This makes it possible to insert one or more cables without having to hold them until the cable duct is closed.

[0026] The spring-loaded hooks can advantageously be arranged distributed along the longitudinal direction of the cable duct. In particular, it can be advantageous to arrange the spring-loaded hooks in groups of at least two, distributed along the longitudinal direction of the cable duct.

[0027] Preferably, each basic element has several spring-elastic hooks that are identical in design and / or orientation.

[0028] Preferably, the guide ribs and the spring-elastic hooks are arranged spaced apart from each other with respect to the longitudinal direction of the cable duct.

[0029] A special application is made possible by the guide ribs and / or the spring-loaded hooks, in which a cable is neatly looped around the guide ribs and / or the spring-loaded hooks. This avoids the need to shorten a cable that is actually too long, which is particularly advantageous if the cable already has a plug or socket that would otherwise have to be removed and then reattached for shortening.

[0030] The fastening device can, in particular, have several identical functional elements. For example, it is advantageous for attaching a curtain if several identical functional elements, designed for fastening an object, are present. In particular, the functional elements can be arranged along a straight line that is parallel to one of the circumferential edges of the fastening device. Such a design is particularly advantageous for hanging an additional curtain or a pleated blind.

[0031] Preferably, the blackout or shading device box is cuboid in shape. This facilitates installation in standard window recesses of buildings.

[0032] The locking device can advantageously be designed to be flat, at least towards the outside of the blackout or shading device box.

[0033] The locking device can have at least one flat wall. In a special embodiment, the locking device has two flat walls arranged perpendicular to each other.

[0034] In a particularly advantageous embodiment, at least one locking means is provided for securing the locking device to the housing, in particular in a way that is releasable without damage and / or tools. For example, the locking device can have detent elements that interact with corresponding detent elements of the housing when the blackout or shading device housing is closed by means of the locking device. Preferably, the functional element is different from the locking means. More generally, it can be advantageously provided that the functional element is not a locking means that serves to attach the locking device to the housing.

[0035] The locking device can be advantageously designed to fit precisely into the inspection opening. Alternatively, it is also possible, for example, that the locking device is designed to fit precisely onto the inspection opening and be secured in this position.

[0036] Preferably, the inspection opening can be completely closed by means of the locking device.

[0037] In a particularly advantageous embodiment, the locking device comprises a first locking device part and a second locking device part separate from the first, by means of which the inspection opening can be completely closed. Such an embodiment is particularly flexible. In particular, it can be advantageously provided that different locking device parts can be combined with one another to form the locking device. In particular, it can be advantageously provided that the locking device parts can be inserted side by side into the inspection opening or that the locking device parts can be placed side by side, precisely fitting onto the inspection opening, especially to completely close the inspection opening.

[0038] In a particularly advantageous embodiment, a connecting element is provided for creating a connection, especially a positive-locking connection, between the locking device components, which can be made without tools and / or without damage. This makes it possible to connect the locking device components to one another, so that the locking device assembled from the locking device components can be handled as a single component. Furthermore, such an embodiment is particularly advantageous with regard to preventing openings through which drafts can enter.

[0039] The locking device can advantageously have at least one flat outer surface. In particular, the blackout or shading device box can be designed to be installed in a building in such a way that the flat outer surface is flush with the building wall. However, it is also possible for the flat outer surface to project beyond or be recessed from the surface of the building wall. It can be particularly advantageous for the outer surface to form part of the outer surface of the blackout or shading device box if the locking device is attached to the box housing in such a way that it closes the access opening. In a particularly advantageous embodiment, the outer surface is designed to be paintable and / or wallpapered and / or plastered over.

[0040] In a particularly advantageous embodiment, the locking device comprises at least one thermal and / or acoustic insulation element. It is particularly advantageous that the functional element is distinct from the thermal and / or acoustic insulation element. More generally, it is advantageous that the functional element is not a thermal and / or acoustic insulation element. Alternatively or additionally, it is more generally possible that the functional element does not serve to accommodate a thermal and / or acoustic insulation element.

[0041] In a particularly advantageous embodiment, the closure device includes an air passage device, in particular an air passage device with an air filter. It is particularly advantageous that the functional element is different from the air passage device. More generally, it is advantageous that the functional element is not an air passage device, in particular not an air passage device with an air filter.

[0042] The closure device can advantageously be made at least partially of plastic. In particular, it can be advantageously provided that at least part of the closure device is manufactured as an injection-molded part, especially as a plastic injection-molded part.

[0043] The blackout or shading device box according to the invention can be designed, in particular, as a window-mounted box, window-mounted roller shutter box, surface-mounted box, and / or new construction box. In a particularly advantageous embodiment, the blackout or shading device box is designed to be connected to a window frame or a window frame, in particular by screwing and / or snapping it into place.

[0044] A system comprising a blackout or shading device housing according to the invention and an energy storage device is particularly advantageous, wherein the functional element is designed to receive the energy storage device and / or to attach the energy storage device to the locking device. In particular, it can be advantageously provided that the energy storage device can be inserted into the housing in such a way that an outer surface of the energy storage device is flush with an outer surface of the locking device. Alternatively or additionally, it can be advantageously provided that a drive motor is arranged in the blackout or shading device housing. The drive motor can serve to drive a winding shaft for rotation or, more generally, to move a blackout device or a shading device.In particular, it can be advantageously provided that the energy storage device supplies the drive motor with electrical drive energy.

[0045] In a particularly advantageous embodiment of the system, at least one lamp, in particular an LED lamp and / or a light strip and / or an LED light strip, is provided. It can be advantageously provided that the energy storage device supplies the lamp with electrical energy. Alternatively or additionally, it can be advantageously provided that the lamp is attached to the locking device by means of the functional element or can be attached to it.

[0046] A blackout or shading device comprising a covering, in particular a roller shutter curtain, an awning curtain or Venetian blind slats, with a blackout or shading device box or system according to the invention is particularly advantageous. The blackout or shading device can advantageously include a blackout element, in particular a curtain, a Venetian blind or a pleated blind, which is attached or can be attached to the closure device by means of the functional element.

[0048] Fig. 1 Figure 1 schematically shows a first embodiment of a blackout or shading device box 1 according to the invention for a blackout or shading device, namely a roller shutter box, which has a box housing 2 with an inspection opening 3. The blackout or shading device box 1 also has a closing device 4 for closing the inspection opening 3.

[0049] The locking device 4 comprises a first locking device part 5 and a second locking device part 6, by means of which the inspection opening 3 can be completely closed. For this purpose, the locking device parts 5 and 6 are inserted side by side into the inspection opening 3.

[0050] The locking device 4 has a first functional element 7 designed to receive an object, namely an energy storage device 8, in particular an electrical one, which may in particular be a battery 9. Specifically, the first functional element 7 has an opening through a wall of the locking device 4 and a receptacle 10 for the energy storage device 8 adjoining the opening inside the blackout or shading device housing. An electrical contact element 11 is arranged in the receptacle 10 such that the insertion of the energy storage device 8 into the receptacle 10, preferably in a form-fitting manner, automatically establishes an electrically conductive contact between the contact element 11 and a mating contact element (not shown) of the energy storage device 8.For example, the contact element 11 can be a socket into which a plug arranged on the energy storage device 8 engages, preferably automatically. Conversely, it is of course also possible for the contact element 11 to be designed as a plug, while the energy storage device 8 has a socket.

[0051] In particular, it may be provided that the energy storage device 8 provides electrical drive energy for operating a (in Figure 1 provides a drive motor (not shown) for rotating a winding shaft 12 onto which a roller shutter curtain 38 can be wound.

[0055] The locking device 4 also has a fifth functional element 23, which is identical in design to the fourth functional element 19 and which also serves to secure the pleated blind 20 to the locking device 4 and thus to the blackout or shading device box 1, preferably in a non-destructive and / or tool-free releasable manner. For this purpose, the fifth functional element 23 has a fastening element 24, which is designed to interact with a further counter-fastening element 25 of the pleated blind 20.

[0056] Instead of being a roller shutter box, the blackout or shading device box 1 can, for example, also be designed as a blackout or shading device box 1 for a venetian blind 39, which is schematically indicated in the figure.

[0057] Figure 2Figure 1 shows a cross-sectional representation of an embodiment of a blackout or shading device box 1 according to the invention, which is not according to the invention and is installed in a window niche, and which is designed as a top-mounted roller shutter box and is connected to a frame 26 of a window 27, for example by means of (not shown) screw and / or snap connections.

[0074] Fig. 11 Figure 1 shows a further embodiment of a blackout or shading device box 1 not according to the invention for a blackout or shading device, which is here exemplified as a roller shutter.

[0075] In this embodiment, the locking device 4 has a functional element 28 designed as a cable passage 42 through which a cable 49 is routed. The cable 49 electrically connects an electric roller shutter drive (not shown) to a socket 43. The cable passage 42 is located on a front surface 44 of the locking device 4. The blackout or shading device box 1 is installed such that the front surface 44 is flush with a building wall 45. The cable 49 is guided through an external cable duct 46, which is fixed to the front surface 44 of the locking device 4. For this purpose, the locking device 4 can have a coupling element (not shown) in the area of ​​a cable passage 42, which is designed to interact with a counter-coupling element (not shown) of the external cable duct 46.

[0076] Fig. 12Figure 1 shows a further embodiment of a blackout or shading device box 1 not according to the invention for a blackout or shading device, which is here exemplified as a roller shutter.

[0077] In this embodiment, the locking device 4 has a functional element 28 designed as a cable passage 42 through which a cable 43 is routed. The cable 49 electrically connects an electric roller shutter drive (not shown) to a socket 43. The cable passage 42 is located on a lateral end face 47 of the locking device 4. The blackout or shading device box 1 is installed with a projection beyond the building wall 45, so that at least part of the locking device 4 projects into the interior of the building. The cable 49 is guided through an external cable duct 46, which is fixed to the lateral end face 47 of the locking device 4. For this purpose, the locking device can have a coupling element (not shown) in the area of ​​a cable passage 42, which is designed to interact with a counter-coupling element (not shown) of the external cable duct 46.

[0078] The Figure 13 Figure 1 shows a further embodiment of a blackout or shading device box 1 not according to the invention for a blackout or shading device, which is here exemplified as a roller shutter.

[0079] In this embodiment, the functional element 28 is designed as a cable duct 48. The cable duct 48 has the distinct advantage that a cable 49 can be concealed and protected, for example, from a left end of the locking device 4 horizontally to the area of ​​the right end of the locking device, for example, to connect a drive motor located in the housing 2 in the area of ​​the right end.

[0080] The cable duct 48 has inwardly directed, spring-elastic hooks 50 designed to partially grip a cable (not shown here). This allows one or more cables to be inserted without having to hold them in place until the cable duct 48 is closed with a cable duct cover 51.

[0081] Figure 14 Figure 48 shows a cross-sectional view through the cable duct 43, in which the spring-loaded hooks 50 can be seen. The cable duct 48 can be closed by snapping it shut with a cable duct cover 51.

[0082] Fig. 15 Figure 4 shows the locking device 4 of a further embodiment of a blackout or shading device box not according to the invention. The locking device 4 has a cable channel 48.

[0083] The cable duct 48 has inwardly directed guide ribs 52. The guide ribs 52 serve to facilitate the sorted and orderly insertion of at least one cable 49. The guide ribs 52 can, in particular, be plate-shaped. Two guide ribs 52 are arranged side by side in pairs, parallel to each other. The guide ribs 52 are distributed along the longitudinal direction of the cable duct 48.

[0084] Furthermore, the cable duct 48 has inwardly directed spring-elastic hooks 51, in particular for partially gripping a cable 49. This makes it possible to insert one or more cables 49 without having to hold them until the cable duct 48 is closed.

[0085] The spring-elastic hooks 51 are arranged in groups of two distributed along the longitudinal direction of the cable duct 48.

[0086] A special application is made possible by the guide ribs 52 and the spring-elastic hooks 51, in which a cable 49 is neatly laid in a loop around the guide ribs 52 and / or the spring-elastic hooks 51, as shown in Figure 15 This is shown. In this way, it is avoided that a cable 49 which is actually too long has to be shortened, which is particularly advantageous if the cable 49 is already fitted with a plug or socket that would first have to be removed and then reattached for shortening.
