Protective device for a building opening and building opening with such a protective device

Description

[0001] The present invention relates to a protective device for a building opening, such as a skylight, and to a building opening with such a protective device. The protective device is designed, in particular, as an insect screen or sunshade and comprises at least one protective element, such as a pleated blind or several louvers, with which the building opening can be covered / closed. The protective device further comprises at least one cord and a cord drive system, wherein the cord drive system, which in particular has at least one spring element, is actuated by means of the at least one protective element during the closing and / or opening of the building opening. The protective device also comprises a profile strip unit having at least one profile strip in which the cord drive system is arranged.

[0002] The invention relates in particular to protective devices in which the cord is arranged entirely within the first profile strip, the at least one protective element, and a strip unit, wherein the at least one protective element is arranged between the first profile strip and the strip unit, and the first profile strip and the strip unit are moved relative to each other to open and / or close the building. With such protective devices, the at least one cord does not need to be attached to the building, for example, to a frame or wall surrounding the building opening. In such protective devices, which are also misleadingly referred to as cordless pleated blinds, the first profile strip containing the cord drive system is arranged at the top of the building opening when installed, so that the strip unit is moved up and down to operate the protective device.

[0003] If a second protective element is to be attached to the building opening, for example as a sunshade in addition to a first protective element designed as an insect screen, it is often difficult for a user to install the cords of the two protective devices easily and quickly.

[0004] Since the cord drive system of known safety devices is located in the first profile strip of the profile strip unit, a suitably configured safety device must be provided to the end user for windows of varying widths. This can lead to incorrect purchases, especially if the end user measures the window width themselves. Furthermore, the supplier must stock a large number of safety devices of varying lengths, each consisting of a single profile strip. A safety device with the features of the preamble of claim 1 is known from US 2009 / 0173459 A1. Another safety device is known from US 2005 / 0194107 A1.

[0005] The object of the present invention is therefore to eliminate at least some of the disadvantages described with reference to the prior art and in particular to provide a protective device whose width can be easily adapted to windows of different widths.

[0006] One solution to the problem is given by the protective device having the features of independent claim 1. Further solutions and advantageous embodiments are given in the preceding and following description as well as in the dependent claims, wherein individual features of the advantageous embodiment can be combined with one another in a technically meaningful manner.

[0007] The problem is solved in particular by a protective device for a building opening, which is designed especially for a window and preferably for a skylight, wherein the protective device comprises at least one protective element, such as a pleated blind (preferably an insect screen or a sunshade) or several slats, a first profile strip, at least one cord, and a cord drive system. The building opening can be covered by means of the at least one protective element, so that, in the case of insect protection, no insects can penetrate through the building opening, and in the case of sun protection, the penetration of sunlight is minimized or completely prevented.The cord drive system, which includes a mechanical element for deflecting and tensioning the cord, is arranged in the first profile strip and is actuated at least indirectly by means of the at least one protective element during the closing and opening of the building opening. Elements of the cord drive system move during closing and / or opening.

[0008] It is further proposed that a second profile strip be provided, wherein the first and second profile strips are telescopic relative to each other, and the profile strip unit thus formed by the first and second profile strips includes the cord drive system. The cord drive system may be arranged section by section in both the first and second profile strips. However, it is preferred that the cord drive system be arranged exclusively in the first profile strip. By telescoping the first and second profile strips relative to each other, the length of the profile strip unit, consisting of the first profile strip and the at least one second profile strip, can be easily adjusted to the width of a window.The supplier of such a protective device therefore only needs to offer one type of protective device for windows of different widths, while the end user can adjust the protective device to the width of the window during installation.

[0009] In other words, the basic idea of ​​the invention is that the cord drive system is arranged in at least one element of a profile strip unit whose length can be changed by telescoping, making the protective device easily adaptable to building openings of different widths.

[0010] In one embodiment, the first profile strip and the at least one second profile strip of the profile strip unit each have a gap extending along the respective profile strip and facing the at least one protective element. A cord deflected by the cord drive system can be easily guided through the respective gap to the protective element and, if necessary, to the strip unit.

[0011] In one embodiment, the first profile strip and at least one second profile strip can be fixed in a position relative to each other. For example, a fixing element, either integrated into one of the profile strips or separate from it, can be provided, which, through active actuation, fixes the profile strips in a position relative to each other. For example, a clamping element or a screw can be provided with which the profile strips are fixed relative to each other.

[0012] The cord drive system includes, in particular, at least one spring element. This spring element is designed and arranged such that it is tensioned during the closing / covering process, for example, by a rotary or linear movement. The spring element can, for example, be a coil spring. Preferably, however, the spring element is a type of helical tension spring.

[0013] The cord drive system further comprises, in particular, one or at least two cord deflection units, wherein the cord deflection units are aligned and arranged relative to each other in such a way as to form a type of pulley system. Preferably, at least four cord deflection units are provided, so that the cord can be received in a profile strip unit that is short relative to the adjustment path of the protective device when the building opening is open, i.e., uncovered.

[0014] While it is possible in principle for the cord to be wound and unwound by the cord drive system, a preferred embodiment provides that the cord drive system comprises a deflection unit fixed to the first profile strip, with at least one, preferably at least two, and particularly preferably at least four or exactly four cord deflection(s), and a deflection unit movable to the first profile strip, with at least one, preferably at least two, and particularly preferably at least or exactly four cord deflection(s). Such a cord drive system provides a compact system based on a pulley principle, enabling the cord to be guided safely even in confined spaces without interfering with itself.

[0015] In this context, it is particularly preferred if the spring element is fixed on one side to a first end face of the first profile strip and on the other side connected to the movable deflection unit, wherein the stationary deflection unit is fixed on a second end face of the first profile strip. In this way, the cord drive system can be easily installed in the first profile strip.

[0016] For particularly easy installation, a cap is provided on the first end face, which can be at least partially inserted into the profile strip and to which the spring element, designed in particular as a helical tension spring, engages, for example, with a hook. The movable deflection unit, with its multiple cord deflections, is movable inside the profile strip and connected to the spring element, also designed in particular as a helical tension spring, with the connection to the movable deflection unit also being achieved via a hook-like engagement of the spring element. For the linearly movable bearing in the profile strip, the outer contour of the movable deflection unit is adapted to the inner contour of the profile strip.

[0017] The stationary deflection unit is preferably designed as a one-piece component, which is inserted into the profile strip on the second end face. This component may incorporate further elements, allowing the protective device to be assembled with its other components.

[0018] The protective device preferably comprises a strip unit, wherein the at least one protective element is arranged between the strip unit on the one hand and the first profile strip and the at least one second profile strip on the other. The strip unit can either serve as a handle unit that the user grips when operating the protective device. For example, if the profile strip unit is fixed in place when installed, the first protective element can be operated by operating the strip unit. Conversely, if the strip unit is fixed to the building opening when installed, the first protective element can be operated by operating the profile strip unit.

[0019] In order to allow the strip unit to be adapted to building openings of different widths, one embodiment provides that the strip unit comprises at least two profile strips that can be telescopically extended relative to each other.

[0020] It may also be provided that the cord is fixed at its ends in the strip unit. Alternatively, it may be provided that the cord is redirected by the strip unit.

[0021] In order to provide lateral guidance for the at least one protective element, the protective device may be provided with two guide rail units, each of which, in the assembled state, is aligned perpendicular to the profile strip unit comprising the first profile strip, and in which at least the at least one protective element is guided during opening and closing, with the profile strip unit or the strip unit optionally also being guided in the guide rail unit during its movement.

[0022] To ensure that the guide rail units can be easily adjusted in length to accommodate different building opening heights, each guide rail unit can have at least two guide rails that can be telescopically extended relative to each other.

[0023] The protective device applies in particular to designs in which, in addition to at least one protective element, a further, second protective element is provided with which the building opening can be covered.

[0024] For example, the design may include at least one first protective element providing insect protection, such as a pleated insect screen, and at least one second protective element providing sun protection, such as a pleated sunshade. It may be designed, for instance, that the building opening is completely covered by either the first or the second protective element. Alternatively, it may be designed that part of the building opening is covered by the first protective element and the other part by the second protective element. For example, the building opening could be partially covered by the sunshade, while the remaining portion is protected from insects by the insect screen.

[0025] At least one second protective element is associated with at least one separate cord, the ends of which, in a preferred embodiment, can be fixed to the building opening or are already fixed in place. The ends of the cord are, in particular, fixed or can be fixed to the frame of the building opening, a reveal surrounding the building opening, or another element of the protective device, outside the strip units associated with the second protective element.

[0026] The second protective element can be assigned at least two (further) strip units, between which the second protective element is arranged and through which, in particular, the at least one cord assigned to the second protective element is passed. These further strip units can each comprise at least two mutually telescopic profile strips, so that the strip units of the second protective element can also be adapted to the width of a building opening.

[0027] Preferably, at least one of these strip units is fixed to the building opening and in particular to a lower end of the building opening, while the second strip unit is arranged to be movable.

[0028] In a particularly preferred embodiment, the lower strip unit is connected to the guide rail units, while the upper, movable strip unit is guided in the guide rail units during its movement.

[0029] In this context, it may also be provided that the movable strip unit of the second protective element can be coupled to the movable (profile) strip unit of the first protective element, for example, mechanically or magnetically, so that the movable (profile) strip units of the different protective elements can be operated simultaneously without a gap forming between them. The movable (profile) strip units are coordinated in such a way that no sunlight or insects can pass through them and enter the building opening.

[0030] If the movable (profile) strip units can be mechanically coupled to each other, a type of hook element can be designed, for example, which engages in a corresponding recess on the other (profile) strip unit. To release this mechanical coupling, it is specifically provided that one strip unit is slightly rotated about its longitudinal axis, thereby releasing the previously existing positive-locking connection, so that the movable (profile) strip units can be operated independently of each other.

[0031] In a preferred embodiment, it is provided that the profile strip unit comprising the first profile strip and the at least one second profile strip is movable with a vertical component in the assembled state of the protective device below the at least one protective element and thus also below the preferably provided strip unit along the building opening.

[0032] The invention and its technical context are explained below using the figures as examples. They show schematic representations. Figure 1: a protective device, Figure 2: a profile strip unit of the protective device, Figure 3: a cord drive system in a partially transparent first profile strip of the profile strip unit, Figure 4: the cord drive system and Figure 5: deflection units and the cord of the cord drive system.

[0033] The in Figure 1 The protective device shown for a roof window comprises a first protective element 1, which is designed as an insect screen pleated blind, and a second protective element 13, which is designed as a sun protection pleated blind.

[0034] The first protective element 1 is associated with a strip unit 10, which has a profile strip 10.1 and a profile strip 10.2, wherein the profile strip 10.1 and the profile strip 10.2 are telescopically extendable relative to each other. The first protective element 1 is also associated with a profile strip unit 14, which comprises a first profile strip 4 and a second profile strip 5 that is telescopically extendable relative to the first profile strip 4.

[0035] The second protective element 13 is assigned a strip unit 15 and a strip unit 16, each of which also has two telescopic profile strips.

[0036] The protective device also includes a guide rail unit 11 and a guide rail unit 12. The guide rail unit 11 comprises a guide rail 11.1 and a guide rail 11.2 that can be extended telescopically. The guide rail unit 12 comprises a guide rail 12.1 and a guide rail 12.2, which can be extended telescopically relative to each other.

[0037] When installed on a roof window, the guide rail units 11 and 12 are attached to the lateral edges of the window reveal, while the slat unit 10 and the slat unit 16 are fixed to the upper and lower edges of the window reveal, respectively. The second protective element 13 has concealed cords whose ends are at least indirectly fixed to the upper and lower edges of the window reveal. It is therefore a pleated blind unit, as is known in itself.

[0038] The first protective element 1, however, has one in the Figure 1 a cord 2 (not shown) is assigned, which comprises a cord drive system 3, which is arranged in the profile strip unit 14 and is further described below with reference to the other figures.

[0039] When mounted on the roof window, the roof window opening can be closed / covered by the first protective element 1 and / or the second protective element 13. For example, a user can pull the profile strip unit 14 downwards so that the building opening is covered by protective element 1. Alternatively, a user can pull the strip unit 15 upwards to cover the building opening with the second protective element 13. It is also possible to cover the upper part of the building opening with protective element 1 and the lower part with protective element 13, in which case the profile strip unit 14 and the strip unit 15 are in contact with each other. To couple the profile strip unit 14 with the strip unit 15, elements such as magnets or mechanical coupling elements can be provided, allowing the profile strip unit 14 and the strip unit 15 to be moved together.In particular, grip elements can be attached to the profile strip unit 14 and the strip unit 15, which have protruding and recessed designs in the form of hooks and receptacles, so that they can mechanically interlock with each other. To release this interlock, at least one strip unit can be rotated about its longitudinal axis, so that the previously existing positive fit can be released.

[0040] During the closing or opening of the building opening, the profile strip unit 14, the strip unit 15 and the protective elements 1 and 13 are guided in the guide rail units 11.

[0041] The telescopic design of the guide rails 11.1, 11.2 and 12.1 and 12.2, as well as the profile strips of the (profile) strip units 10, 14, 15, and 16, allows the end user to easily adjust the protective device to the height and width of the building opening before installation. In particular, it can be provided that the strip units 10 and 16 are connected to the guide rail units 11 and 12 via plug connectors, so that the guide rail units 11 and 12 and the (profile) strip units 10, 14, 15, and 16 can be supplied to the user separately. The user can then adjust the length of the protective elements 1 and 13 to the width of the building opening by cutting them to size.

[0042] While the cords of the second protective element 13 can be routed, for example, in the guide rail units 11 and 12, the protective element 1 has a so-called cordless guide system. In this system, a cord drive system is integrated into the profile strip unit 14, which almost completely accommodates the cord 2, particularly when the protective element is open. This prevents the cord of the second protective element 13 from having to pass close to the cord 2 of the first protective element 1. Such interference with the cord systems is further reduced by the fact that the cord drive system 3 of the first protective element 1 is located in the profile strip unit 14, which is movable relative to the guide rail units 11 and 12, and not in the strip unit 10. The profile strip unit 14 is thus positioned below the strip unit 10 and below the first protective element 1 when installed.

[0043] In Figure 2A perspective view of the profile strip unit 14 is shown, from which it can be seen that the first profile strip 4 and the second profile strip 5 are arranged telescopically relative to each other, wherein the profile strips 4, 5 each have a gap 4.1 and 5.1 through which the cord 2 of the in Figure 2 The cable drive system 3, which is not clearly shown, can be routed through it. A connection to the first protective element 1 can also be established through the gap 5.1 or 4.1.

[0044] At the ends of the profile strip unit 14, corner connectors can be seen inserted into the profile strips 4 or 5, with which the profile strip unit 14 can be connected to the guide rail units 11 or 12.

[0045] In the Figures 3 and 4 The cord drive system 3 is shown, wherein in Figure 3 The first profile strip 4 is shown in a partially transparent state.

[0046] The cord drive system 3 comprises a spring element 7 designed as a helical spring, which is fixed on one side to a first end face 4.2 of the first profile strip 4 by means of a cap-like fastening element 17 and on the other side is connected to a movable deflection unit 9 of the cord drive system 3. The movable deflection unit 9 is slidably arranged in the first profile strip 4.

[0047] The cord drive system 3 also includes a stationary deflection unit 8, which is formed integrally with the plug-in connection element for the guide rail unit 12. The stationary deflection unit 8 is thus arranged at an end of the first profile strip 4 associated with a second end face 4.3.

[0048] As especially from Figure 5As can be seen, both the stationary deflection unit 8 and the movable deflection unit 9 have four cord deflections 6 for the cord 2. The cord 2, the movable deflection unit 9, and the stationary deflection unit 8 thus form a type of pulley system. During the closing of the building opening by means of the first protective element 1, the cord 2 is pulled out of the profile strip unit 14, whereby the movable deflection unit 9 moves towards the stationary deflection unit 8 and the spring element 7 is tensioned. When the profile strip unit 14 is returned to its upward position, the movable deflection unit 9 then moves away from the stationary deflection unit 8 due to the spring force provided by the spring element 7.

[0049] Since the fastening element 17 securely fixes the spring element 7 in the first profile strip 4, but does not protrude beyond the outer contour of the first profile strip 4, the first profile strip 4 can be inserted as an inner profile strip into the second profile strip 5, which is designed as an outer profile strip. This allows a pleated blind system, which can be easily adjusted in width, to be combined with a so-called cordless curtain system. Reference symbol list
