Description

[0001] The present invention relates to a protective device for covering a building opening, such as a window, surrounded by a frame. The window comprises the frame and a window sash, which is generally pivotable relative to the frame. The invention relates in particular to a protective device designed as an insect screen, which can be mounted on the outside of the frame so that no insects can enter the building when the window sash is open.

[0002] The protective device typically has a rectangular frame. The first frame members are vertically oriented when the device is mounted on the frame, while the second frame members are horizontally oriented when mounted and oriented perpendicular to the first. Each frame member comprises at least one profile strip. In particular, each frame member may comprise exactly one profile strip, in which case the length of the profile strip must be adjusted to the size of the frame. Alternatively, each frame member may have at least two profile strips that are telescopically adjustable relative to each other, allowing the frame members to be easily adjusted to the size of the frame by telescoping. For this purpose, each frame member has, in particular, an outer profile strip into which at least one inner profile strip can be inserted.

[0003] The frame defines, in particular, a frame plane, wherein the frame has an outer and an inner side within the frame plane, and, orthogonal to the frame plane, a front and a back. The outer side of the frame thus faces outwards within the frame plane, while the inner side faces the space enclosed by the frame, which is covered by the protective element. The front of the frame is the side that, when mounted on the frame, faces away from the frame, while the back, when mounted, faces the frame.

[0004] Adjacent frame struts can be connected to each other in a suitable manner. For example, corner connectors can be provided, each having at least two connecting legs, the connecting legs being inserted into the profile strips of adjacent frame struts, in particular by means of a force-fit connection.

[0005] The protective device also includes a protective element that is attached to or can be attached to the frame and is stretched across it. This protective element can, for example, be designed as an insect screen / net. Alternatively, the protective element can, for example, be designed as a pollen screen to prevent pollen from entering.

[0006] Furthermore, the protective device can include a clamping element with which the protective element is fixed to the frame. For example, the profile strips of the frame strut can have a fixing contour extending along their longitudinal extent, wherein a clamping contour of the clamping element is aligned with the fixing contour such that the protective element is fixed to the fixing contour of the profile strip by means of the clamping element. The clamping element can, for example, be designed as a bead in a known manner. In addition to the clamping contour, the clamping element can include further functional elements. For example, a sealing lip can be provided on the clamping element to seal the protective device against the frame.

[0007] The protective device also includes at least one retaining element for attaching the protective device to the frame. In particular, exactly two or exactly four retaining elements are provided with which the protective device can be attached to the frame and, in particular, hooked onto the frame. The retaining elements can, for example, be designed as mounting brackets. Such a mounting bracket includes, in particular, a fastening section that is attached to the frame, especially to the profile strips of the frame strut or to a corner connector, and extends, in particular, in the direction of the longitudinal dimension of the profile strip, as well as a spacer oriented orthogonally to the fastening section, which, in the fastened state, rests on a top surface of the frame facing the building opening, and a retaining leg that, in the fastened state, engages behind the frame.These retaining elements allow the protective device to be hung, in particular, on the frame.

[0008] It is now known, on the one hand, to attach the retaining elements indirectly to the frame strut and, in particular, to the profile strip of the frame strut by means of additional components. For example, DE 10 2018 106 444 B4 discloses that the retaining element is attached to the profile strip via a functional component as an additional component. The use of additional components can result in play between the retaining element and the frame.

[0009] On the other hand, it is known to attach the retaining element to the corner connector. For example, EP 2 484 855 B1 discloses that the spacer of the mounting bracket is inserted through the corner connector and the fastening section is bent over on the back of the corner connector.

[0010] It is also desirable that the retaining element be positioned as far inward as possible from the frame so that the protective device frame can overlap the window frame as much as possible. This is because seals are typically attached to the frame members of the protective device frame, resting on the outside of the window frame when installed. A particularly good seal is achieved with the greatest possible overlap. The profile strips of the frame members and, if applicable, the corner connectors can have corresponding channels to accommodate the seals. When the retaining elements are attached to the corner connector, this arrangement already results in a slight overlap between the protective device frame and the window frame.

[0011] From EP 4 001 583 A1, for example, it is known that the spacer and the retaining leg of a mounting bracket are offset towards the inside of the frame with respect to the fastening section, wherein the fastening section of the retaining element is attached to the corner connector. Protective devices with the features of the preamble of claim 1 are known from DE 10 2015 108 275 A1 and DE 20 2018 100 888 U1. EP 1 596 034 A2 discloses a protective device with a spring clip as a retaining element.

[0012] The object of the present invention is to eliminate at least some of the disadvantages described with reference to the prior art and in particular to provide a protective device in which the retaining element is securely and without play attached to the frame.

[0013] One possible solution to this problem is given by the protective device with 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 embodiments can be combined with one another in a technically meaningful manner.

[0014] The problem is solved in particular by providing a profile strip, preferably at least one profile strip of each frame strut, or more preferably each profile strip of the frame struts, with a receptacle for the retaining element, and by arranging the retaining element, at least partially, directly in the receptacle of the profile strip. The receptacle can, for example, extend over the entire length of the profile strip, whereby the receptacle is designed as a kind of channel in the profile strip, defined by the cross-sectional contour of the profile strip.

[0015] In other words, the basic idea of ​​the invention is that the retaining element is attached directly and immediately to the profile strip, without the use of any additional components. For this purpose, the profile strip and the retaining element are designed to be compatible such that the portion or section of the retaining element positioned in the profile strip's receptacle is held securely in place by friction and / or form-fitting action. Therefore, no additional components are required to attach the retaining element to the frame.

[0016] The retaining element is designed as a mounting bracket comprising a mounting section, a spacer, and a retaining leg, wherein the mounting element with the mounting section is at least partially inserted into the receptacle. The mounting bracket is made of a metal strip, with the mounting section arranged at a right angle to the spacer. Furthermore, the retaining leg is arranged at a right angle to the spacer and aligned parallel to the mounting section. The mounting section, the spacer, and the retaining leg are arranged, in particular, in the same plane.

[0017] The receptacle, defined by the cross-sectional contour of the profile strip, is preferably sized to match the mounting section of the retaining element such that the mounting section can be inserted into the receptacle from an end face of the profile strip and is held there by a positive locking mechanism. The profile strip is, in particular, made of aluminum, and the retaining element is made of metal. The mounting section of the retaining element and the receptacle are dimensioned, in particular, such that a type of compression connection is created when the mounting section is inserted into the receptacle.

[0018] To achieve the greatest possible overlap between the frame of the protective device and the frame, one embodiment provides that the receptacle for the retaining element is located adjacent to the inside of the frame. Accordingly, the receptacle is formed in a region of the profile strip that at least partially forms the inside of the frame. Thus, the retaining element and the portion of the retaining element that overlaps the frame when fastened are positioned as far inward as possible, so that the frame overlaps the frame by, for example, more than 50%, preferably more than 70%, of its width.

[0019] The recess can be designed, for example, as a completely enclosed channel within the profile strip. However, it can also be designed so that the recess is partially open on one side.

[0020] In this context, it is particularly intended that the fixing contour for receiving the clamping element is designed as a contour open to the front, into which the clamping element, designed in particular as a keder, can be inserted to fix the protective element. It is now specifically proposed that the receptacle for the retaining element be arranged directly adjacent to the fixing contour, with the receptacle being arranged particularly directly adjacent to the front or the back. The fixing contour and the receptacle are, so to speak, arranged one above the other in the profile strip from the back to the front.

[0021] If adjacent frame members are connected to each other via corner connectors, the retaining element, and in particular the fastening section of the retaining element, is arranged offset towards the inside of the frame in the profile strip. The connecting leg of the corner connector is, for example, arranged in a receiving channel provided for this purpose in the profile strip, with the receiving channel being arranged towards the outside of the frame.

[0022] In one embodiment, it can be provided that the retaining element and, in particular, the fastening section of the mounting bracket on the frame is inserted exclusively into the receptacle.

[0023] In an alternative embodiment, it can be provided that the retaining element and, in particular, the fastening section of the retaining element are arranged at least partially in or on the corner connector.

[0024] In this context, it may be provided that the corner connector has a mounting area for the retaining element, and that the retaining element can be pre-assembled in this mounting area in such a way that the retaining element is inserted into the receptacle when the connecting leg of the corner connector is inserted into the profile strip. Such pre-assembly of the retaining element on the corner connector makes the protective device easier to install, especially for the end user, as they can insert the corner connector and the retaining element together / simultaneously into the profile strip of the frame strut.

[0025] The fastening area of ​​the corner connector is designed in particular such that the retaining element can be pre-assembled without tools and in a force-fit and / or form-fit manner, for which purpose the fastening area includes in particular a first recess for the fastening section of the retaining element and a second recess for the spacer of the retaining element.

[0026] In this context, it can be provided, in particular, that the spacer can be inserted into the second recess when the retaining element is tilted, whereby when the retaining element inserted in the second recess is tilted back, the fastening section moves into the first recess. The second, in particular slot-like, recess is aligned approximately parallel to the end face of the profile strip into which the retaining element is inserted, with the first, in particular slot-shaped, recess extending parallel to the longitudinal dimension of the profile strip. Adjacent to the first recess, a stop, for example in the form of a projection, can be formed against which the fastening section of the retaining element comes into contact when the retaining element is tilted back.

[0027] The present invention relates in particular to a protective device with a frame that is easily adjustable in size, wherein all frame struts have at least one outer profile strip and at least one inner profile strip.

[0028] The invention and its technical context are explained below using the figures as examples. They show schematic representations. Figure 1: an exploded view of a profile strip, a corner connector and a retaining element; Figure 2: another embodiment of a corner connector and a retaining element at the beginning of an assembly process; Figure 3: the corner connector and the retaining element according to Figure 2 During the assembly process, Figure 4: the corner connector and the retaining element; at the end of the assembly process, Figure 5: the corner connector and the retaining element of the Figures 2 to 4 in a state inserted into a profile strip and Figure 6: a protective device with the elements of Figures 2 to 5 .

[0029] In Figure 6 Figure 1 shows a protective device for covering a building opening surrounded by a frame. The protective device comprises a frame 1 with two vertically oriented first frame struts 1.1a and 1.1b, and with two horizontally oriented second frame struts 1.2a and 1.2b. The frame struts 1.1a, 1.1b, 1.2a, and 1.2b are each formed by a profile strip 2. In an embodiment not shown, the frame struts can each also comprise two profile strips that are telescopically extendable relative to each other.

[0030] The profile strips of 2 adjacent frame struts are connected by means of corner connectors 10 to form a rectangular frame 1.

[0031] The frame 1 defines a frame plane, wherein the frame 1 has in the frame plane a frame outer side 9.1 and a frame inner side 9.2, as well as a front side 9.3 pointing away from the frame and a back side 9.4 pointing towards the frame.

[0032] The frame has seals 8 on its rear side 9.4 adjacent to the outer side 9.1 of the frame, which are inserted into corresponding channels in the profile strips 2 and extend into corresponding channels in the corner connectors 10.

[0033] The profile strips 2 have fixing contours 7 into which a clamping element 4, realized as a keder, is inserted, with which a protective element 3, for example an insect screen or a pollen screen, is attached to the frame 1.

[0034] In addition, the protective device has four retaining elements 5 with which the protective device can be attached to a frame, for example to a window frame.

[0035] According to the invention, it is now proposed that the profile strip 2 has a receptacle 6 for the retaining element 5, and that the retaining element 5 is inserted directly into the receptacle, at least partially.

[0036] This is in Figure 1 One embodiment is shown. From the Figure 1 It can be seen that the corner connector 10 has a first connecting leg 10.1 and a second connecting leg 10.2. The connecting legs 10.1 and 10.2 are inserted into corresponding channels of the profile strips 2 of adjacent frame struts.

[0037] The retaining element 5, designed as a mounting bracket, has a fastening section 5.1, a spacer 5.2 arranged at right angles to it, and a retaining leg 5.3 which is parallel to the fastening section 5.1 and perpendicular to the spacer 5.2. When mounted on a frame, the retaining element 5 rests with the spacer 5.2 on an inner side of the frame facing the building, while the retaining leg 5.3 engages behind the frame.

[0038] As from Figure 1As can be seen, the receptacle 6 for the fastening section 5.1 of the retaining element 5 is formed below the fixing contour 7. The receptacle 6 is formed by the base of the profile strip 2 and by two projections that extend along the longitudinal extent of the profile strip 2. The receptacle, in particular with its projections, is such that the fastening section 5.1 is held force-fit in the receptacle 6 after being inserted from the end face of the profile strip 2. Figure 1 In the embodiment shown, the fastening section 5.1 of the retaining element is arranged exclusively in the receptacle 6.

[0039] By directly inserting the retaining element 5 into the receptacle 6, a precise position of the retaining element 5 is predetermined without the need for any further components or tools.

[0040] Since the inlet 6 is located immediately adjacent to the inside of the frame 9.2, the frame 1 can overlap the outer frame to a large extent, so that the seal 8 is securely in contact with the outside of the outer frame.

[0041] In the Figures 2 to 5 Another embodiment of a corner connector and an arrangement of the retaining element 5 is shown, which is also within the scope of the Figure 6 has been realized.

[0042] While in the embodiment of Figure 1 The retaining element 5 is arranged exclusively in the receptacle of the profile strip 2 in the embodiment of the Figures 2 to 5The retaining element 5 is attached section by section to / in the corner connector 10. According to this embodiment, the retaining element 5 can be pre-assembled on the corner connector 10 so that the fastening section 5.1 of the retaining element 5 can be inserted into the receptacle 6 when the connecting leg 10.1 is simultaneously inserted into the profile strip 2.

[0043] For this purpose, the corner connector 10, which has a first connecting leg 10.1 and a second connecting leg 10.2, has a fastening area 11 on which the retaining element 5 can be pre-assembled without tools in a force-fit and form-fit manner.

[0044] The fastening area 11 comprises a first slot-shaped recess 11.1, which is oriented approximately perpendicular to the direction of extension of the first connecting leg 10.1. The fastening area 11 also comprises a second recess 11.2, which is oriented approximately parallel to the first connecting leg 10.1 and, like the first recess 11.1, is formed in a region of the corner connector 10 that is not inserted into a profile strip 2. The fastening area 11 also comprises a projection 11.3.

[0045] As can be seen especially from the in the Figures 2 to 4 As can be seen from the assembly steps shown, the first recess 11.1 is designed such that the retaining element 5 can be inserted into the first recess 11.1 in a tilted state with the spacer 5.2, whereby at the same time the fastening section 5.1 of the retaining element 5 is arranged adjacent to the second recess 11.2 (see in particular Figure 3). When the retaining element 5 is swung back, the fastening section enters the second recess 11.2 and is held there by contact with the projection 11.3. Reference symbol list
