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 sun protection device and comprises at least one protective element, such as a pleated blind or several slats, 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 first profile strip, in which the cord drive system is arranged.

[0002] The invention particularly relates 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, the at least one protective element being arranged between the first profile strip and the strip unit, and the first profile strip and the strip unit being moved relative to one another to open and / or close the building. In such protective devices, the at least one cord does not have to be attached to the building, for example to a frame surrounding the building opening or to a wall surrounding the building opening. In such protective devices, which are also misleadingly referred to as cordless pleated blind arrangements, the first profile strip containing the cord drive system is arranged at the top of the building opening in the assembled state, such that the strip unit is moved up and down to actuate the protective device.

[0003] If a second protective element is to be attached to the building opening, which, for example, is designed as a sun protection 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 quickly and easily.

[0004] Since the cord drive system of the existing safety guards is located in the first profile strip of the profile strip unit, a correspondingly configured safety guard must be provided to the end user for windows of different widths. This can lead to incorrect purchases, especially if the end user measures the window width themselves. In addition, the supplier must stock a variety of safety guards with different lengths for the profile strip unit, which only has one profile strip.

[0005] The object of the present invention is therefore to at least partially eliminate 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] A solution to the problem is provided by the protective device having the features of independent claim 1. Further solutions and advantageous developments are specified in the above and following description as well as in the subclaims, wherein individual features of the advantageous development can be combined with one another in a technically expedient manner.

[0007] The object is achieved in particular by a protective device for a building opening, which is designed in particular for a window and preferably for a roof window, wherein the protective device comprises at least one protective element, such as a pleated blind (preferably an insect screen pleated blind or a sun protection pleated blind) 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 an insect screen, no insects can penetrate through the building opening, and in the case of a sun screen, the penetration of sunlight is minimized or completely prevented.The cord drive system, which in particular has a mechanical element for deflecting the cord 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 the closing and / or opening processes.

[0008] It is further proposed that a second profile strip is provided, wherein the first profile strip and the second profile strip are telescopic relative to one another, wherein the profile strip unit thus formed by the first profile strip and the second profile strip comprises the cord drive system. In this case, it can be provided that the cord drive system is arranged in sections in both the first and the second profile strip. However, it is preferred that the cord drive system is arranged exclusively in the first profile strip. By telescoping the first profile strip and the second profile strip relative to one another, the length of the profile strip unit consisting of the first profile strip and the at least one second profile strip can be easily adapted to the width of a window.The supplier of such a guard therefore only needs to offer one type of guard for different window widths, while the end user can adapt the guard 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, whereby the protective device can be easily adapted to building openings of different widths.

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

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

[0012] The cord drive system, in particular, comprises at least one spring element. The at least one 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 at least one spring element can be formed, for example, by a spiral spring. However, the at least one spring element is preferably formed by a type of helical tension spring.

[0013] The cord drive system also comprises, in particular, one or at least two cord deflectors, wherein the cord deflectors are particularly aligned and arranged relative to one another in such a way that a type of pulley system is formed. Preferably, at least four cord deflectors are provided so that, when the building opening is open (i.e., uncovered), the cord can be accommodated in a profile strip unit that is short relative to the adjustment path of the protective device.

[0014] While it can in principle be provided that the cord is wound and unwound by the cord drive system, in a preferred embodiment it is provided that the cord drive system has a deflection unit that is immovable relative to the first profile strip and has at least one, preferably at least two, particularly preferably at least four or exactly four cord deflection(s), and a deflection unit that is movable relative to the first profile strip and has at least one, preferably at least two, particularly preferably at least or exactly four cord deflection(s). With such a cord drive system, a compact system can be provided that uses a pulley principle, with which the cord can be guided safely even in confined spaces without interacting with itself.

[0015] In this context, it is particularly preferred if the spring element is fixed on the one hand to a first end face of the first profile strip and on the other hand is connected to the movable deflection unit, with the immovable deflection unit being 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 simple installation, a type of cap is formed on the first end face, which can be at least partially inserted into the profile strip and into which the spring element, in particular designed as a helical tension spring, engages, for example with a hook. The movable deflection unit, with in particular the plurality of cord deflections, is movable inside the profile strip and is connected to the spring element, in particular designed as a helical tension spring, wherein the connection to the movable deflection unit is also made via a hook-like engagement of the spring element. For the in particular linearly movable mounting in the profile strip, the outer contour of the movable deflection unit is adapted to the inner contour of the profile strip.

[0017] The immovable deflection unit is preferably designed as a one-piece component that is inserted into the profile strip on the second end face. Additional elements can be formed on this component, via which the protective device can be assembled with its other components.

[0018] The protective device preferably also 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 serve either as a handle unit that the user grasps when they want to operate the protective device. If, for example, the profile strip unit is fixed in place in the assembled state, the first protective element can be actuated by operating the strip unit. If, however, the strip unit is fixed in place at the building opening in the assembled state, the first protective element can be actuated by operating the profile strip unit.

[0019] In order to ensure that the strip unit can be adapted to building openings of different widths, one embodiment provides that the strip unit comprises at least two profile strips that can be telescoped relative to one another.

[0020] It may also be provided that the cord is secured by its ends in the strip unit. Alternatively, it may be provided that the cord is deflected with the strip unit.

[0021] In order to provide lateral guidance for the at least one protective element, it can be provided that the protective device has two guide rail units, each of which, in the assembled state, is aligned at right angles 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, wherein, if appropriate, the profile strip unit or the strip unit is also guided in the guide rail unit during its movement.

[0022] To ensure that the length of the guide rail units can be easily adjusted to suit building openings of different heights, the guide rail units can each have at least two guide rails that can be telescoped relative to one another.

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

[0024] For example, it can be provided that the at least one first protective element provides insect protection, for example in the form of a pleated insect screen, and the at least one second protective element provides sun protection, for example in the form of a pleated sun screen. For example, it can be provided that the building opening is completely covered by the at least one first protective element or by the at least one second protective element. However, it can also be provided that part of the building opening is covered by the at least one first protective element and the other part of the building opening is covered by the at least one second protective element. For example, the building opening can be partially covered by the sun protection element, while the remaining part is protected against the penetration of insects by the insect protection element.

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

[0026] At least two (further) strip units can be assigned to the second protective element, 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 in a fixed position at the building opening and in particular at a lower end of the building opening, while the second strip unit is arranged to be movable thereto.

[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 can 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 the movable (profile) strip units. The movable (profile) strip units are coordinated with one another in such a way that no sunlight or insects can pass between them through the building opening.

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

[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 along the building opening below the at least one protective element and thus also below the preferably provided strip unit in the mounted state of the protective device.

[0032] The invention and the technical environment are explained below by way of example with reference to the figures. They show schematically 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 Figure 1 The protective device for a roof window shown 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 assigned a strip unit 10, which comprises 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 one another. The first protective element 1 is also assigned 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, which also each have two profile strips that can be telescoped towards one another.

[0036] The protective device also comprises 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 telescoped relative to each other. The guide rail unit 12 comprises a guide rail 12.1 and a guide rail 12.2 that can be telescoped 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 strip unit 10 and the strip unit 16 are fixedly mounted to an upper and lower edge of the window reveal, respectively. The second protective element 13 is assigned invisible cords, the ends of which are at least indirectly fixed to the upper and lower edges of the window reveal, respectively. This is thus a conventional pleated blind unit.

[0038] The first protective element 1, however, is a Figure 1 not shown cord 2, 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 the protective element 1. However, a user can also pull the strip unit 15 upwards to cover the building opening using the second protective element 13. It is also possible to cover the upper part of the building opening using the protective element 1 and the lower part of the building opening using the protective element 13, in which case the profile strip unit 14 and the strip unit 15 abut one another. In order to couple the profile strip unit 14 to the strip unit 15, elements such as magnets or mechanical coupling elements can be provided so that the profile strip unit 14 and the strip unit 15 can be moved together.In particular, gripping elements can be attached to the profile strip unit 14 and the strip unit 15, which have projection and recess configurations in the form of hooks and receptacles, so that they can mechanically lock together. To release this locking, at least one strip unit can be rotated about its longitudinal axis, so that the previously existing positive locking 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] Due to the telescopic nature of the guide rails 11.1, 11.2 or 12.1 and 12.2, as well as the profile strips of the (profile) strip units 10, 14, 15, and 16, the protective device can be easily adapted to the height and width of the building opening by an end user 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-in connections, so that the guide rail units 11 and 12 and the (profile) strip units 10, 14, 15, and 16 can be provided to the user separately. The length of the protective elements 1 and 13 can then be adapted by the user to the width of the building opening by cutting them to size.

[0042] While the cords of the second protective element 13 can be laid, for example, in the guide rail units 11 and 12, the protective element 1 has a so-called cordless guide system in which a cord drive system is formed in the profile strip unit 14, which almost completely accommodates the cord 2, especially in an open state. This prevents a cord of the second protective element 13 and the cord 2 of the first protective element 1 from having to be guided closely past one another. 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 arranged in the profile strip unit 14, which is movable relative to the guide rail units 11, 12, and not in the strip unit 10. The profile strip unit 14 is thus arranged below the strip unit 10 and below the first protective element 1 in the assembled state.

[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 one another, wherein the profile strips 4, 5 each have a gap 4.1 and 5.1 through which the cord 2 of the Figure 2 not clearly shown. 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 and 5, with which the profile strip unit 14 can be connected to the guide rail units 11 and 12, respectively.

[0045] In the Figures 3 and 4 The cord drive system 3 is shown, where 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 secured on the one hand 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 hand, 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 is particularly evident from Figure 5As can be seen, both the immovable 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 immovable deflection unit 8 thus form a type of pulley. 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 is moved towards the immovable deflection unit 8 and the spring element 7 is tensioned. When the profile strip unit 14 is returned upwards, the movable deflection unit 9 then moves away from the immovable 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. Thus, a pleated blind system with an easily adjustable width can also be combined with a so-called cordless curtain system. List of reference symbols
