Description

[0001] The present invention relates to a protective device, in particular an insect screen for a window, comprising a tension frame, wherein the tension frame comprises first frame struts and second frame struts oriented transversely to the first frame struts, and preferably connectors, wherein the connectors connect the frame struts to each other, further comprising a net, clamping elements with which the net is fixed to the tension frame, and at least one mounting device by means of which the tension frame can be attached to a building having a building opening, wherein the frame struts each have at least one clamping design extending along their longitudinal extent, and the clamping elements for fixing the net can be attached to the clamping design of the frame strut.

[0002] From EP 3 138 990 B1, which originates from the applicant, a protective device is known, in which the frame struts each have at least one outer profile strip and an inner profile strip that can be telescopically inserted into the outer profile strip. The protective device also includes an adapter profile strip that can be attached to an (auxiliary) projection of the inner profile strip in an area extending beyond the outer profile strip. A (main) projection on the outer profile strip and the adapter profile strip thus provide an outer contour extending over the entire frame strut, to which the net can be attached by means of a single clamping strip.

[0003] From EP 2 484 855 B1, an insect screen device for a window is known, according to which a mounting element designed as a hanging element is attached to a (corner) connector arranged between two frame members. The arrangement of the hanging element on the corner connector of the screen device has the disadvantage that an overlap of the tension frame with the window frame cannot always be ensured. This is because, due to the arrangement of the hanging element in the outer corner area of ​​the tension frame in both horizontal and vertical directions, only a relatively small area of ​​the tension frame is available for overlap with the window frame, especially since the hanging element must engage behind the window frame.

[0004] A similar disadvantage is associated with mounting elements that are arranged in a vertical frame strut of the protective device and are optionally slidable along the vertical frame strut, so that only a small area is available horizontally outside next to the mounting elements, which can be overlapped with a window frame. Such a protective device is known, for example, from DE 10 2011 011 113 A1.

[0005] It is also known, for example, from DE 10 2010 049 782 A1, to insert mounting elements of a protective device into undercut designs of a profile strip of a frame strut, for which purpose the mounting elements have a type of T-nut that must be inserted into the profile strip from an end face. A disadvantage of this is that the mounting elements must be inserted into the profile strips before the corner connectors are mounted on them, so that, under certain circumstances, precise alignment of the mounting elements on the profile strips may not be possible afterwards, or that additional securing means must be provided to fix the mounting elements in the profile strips.

[0006] Furthermore, EP 1 457 638 A1 discloses that a mounting element, designated as a retaining claw, can be inserted directly into the profile strip. For this purpose, the profile strip has a separate groove with teeth that correspond to teeth on the retaining claw. With such a specific design, the separate groove with the teeth must be taken into account during the design of the profile strip, meaning that the retaining claw cannot be combined with other profile strips.

[0007] A protective device is known from US 8,146,647 B1, in which the net is temporarily held to the frame by means of clip elements that can be clipped into a groove in the frame struts, before the net is permanently fixed by means of a keder. A protective device with the features of the preamble of claim 1 is known from DE 20 2004 005 584 U1.

[0008] The object of the present invention is therefore to eliminate the disadvantages described with reference to the prior art and in particular to provide a protective device in which the mounting device allows a greater overlap of the tension frame with the frame and in which the mounting device is easy to install.

[0009] The problem is solved by a protective device with the features of the independent claim. Advantageous embodiments of the protective device are specified in the dependent claims and in the description, whereby individual features of the advantageous embodiments can be combined with one another in a technically meaningful manner.

[0010] The problem is solved in particular by a protective device with the aforementioned features, the mounting device of which includes a fastening element that can be clipped onto the clamping design.

[0011] The basic idea of ​​the invention is that the mounting device can be attached to the clamping frame after the frame has already been assembled, and that the mounting device can be attached at any point along the clamping element. For this purpose, the mounting device is pressed onto or into the clamping element approximately perpendicular to the plane spanned by the clamping frame, whereby the fastening element is elastically deformed and, at the end of the clipping process, elastically springs back, thus engaging at least a section of the clamping element. After the pressing process, the fastening element of the mounting device is therefore locked into the clamping element.

[0012] As part of the clamping design, the frame struts either have a channel or a projection extending along their direction of extension. The projection, in particular, has a head section that is integrally connected to the rest of the frame strut via a web, the head section having a greater cross-sectional width transverse to its longitudinal extent than the web. The channel, in particular, has a gap extending along the direction of extension of the frame strut, with a channel section below the gap being wider than the gap itself.

[0013] Adjacent frame members can be connected to each other, in particular by means of so-called corner connectors, whereby the corner connectors have two legs, preferably oriented orthogonally to each other, which are inserted into the frame members. Alternatively, adjacent first and second frame members could also be welded together or connected by other suitable means.

[0014] In principle, each frame strut can consist of exactly one profile strip with the channel or projection. In this case, the size of the tension frame can be adjusted by a user by shortening the profile strips.

[0015] To make it easier to adjust the size of the tension frame, the frame struts can each have at least one outer profile strip and at least one inner profile strip that can be telescopically inserted into the outer profile strip. The user can then adjust the size of the tension frame by telescoping the struts.

[0016] In this case, both the outer and inner profile strips feature a channel or projection as part of the clamping design. To ensure a uniform clamping contour extending across the entire frame strut, the clamping design can include an adapter profile strip attached to the inner profile strip. The contour of the adapter profile strip, together with the channel or projection contour formed integrally on the outer profile strip, creates a continuous clamping contour. The adapter profile strip can therefore be mounted either in the channel or on the projection of the inner profile strip. For this purpose, the adapter profile strip can be clipped into the channel or onto the projection of the inner profile strip, particularly perpendicular to the plane spanned by the clamping frame.

[0017] The cross-sectional contour of the adapter profile strip therefore partially corresponds to the cross-sectional contour of the outer profile strip channel or the outer profile strip projection. When installed, the adapter profile strip, positioned in this way, also prevents the inner profile strip from being inserted into the outer profile strip, thus allowing the overall length of the frame strut to be determined by the adapter profile strip.

[0018] Thus, the net can be attached to the frame strut with a single clamping element per frame strut by pressing / clipping the clamping element onto the clamping contour transversely to the plane spanned by the frame strut, with the net and its section to be fixed being located between the clamping element and the clamping contour.

[0019] The mounting element of the attachment device can, for example, be clipped into the channel or onto the projection of the frame strut. If the frame strut includes an outer profile strip and an inner profile strip, the mounting element can be clipped onto the projection or into the channel of the outer profile strip and / or onto the projection or into the channel of the inner profile strip. It is also possible for the mounting element to be clipped onto the adapter profile strip.

[0020] In one embodiment, it is proposed that an end face of the fastening element, and in particular the end face of a clip-on section of the fastening element, is in contact with an end face of the adapter profile strip, wherein the clip-on section has a contour corresponding to the adapter profile strip. In this case, the clamping element can be clipped onto the clip-on section of the fastening element to secure the mesh.

[0021] In an alternative embodiment, the fastening element can also partially assume the function of the clamping element. In this case, an end face of the fastening element, and in particular an end face of the clip-on section of the fastening element, rests against the clamping element for the corresponding frame strut.

[0022] The mounting device can therefore be adapted to the clamping design of the frame struts with maximum flexibility.

[0023] While it is possible in principle for the mounting device to be a single piece, thus incorporating at least one clip-on section and, for example, a hanging element as a further component of the fastening element, it is preferred that the mounting device be multi-part, and in particular two-part. In this case, the mounting device comprises, in addition to the fastening element that can be clipped onto the clamping mechanism, a separate mounting element that can be connected to the fastening element. The mounting element can, for example, be designed as a hook-shaped, and in particular an L-shaped, hanging element with which the tension frame can be hung on a window frame. If the protective device is designed as an insect screen door, the mounting element can also be designed as a hinge.

[0024] To connect the fastening element to the mounting element, the fastening element can have a receptacle for the mounting element. The receptacle is designed such that the mounting element can be inserted into the receptacle in one direction and is fixed in the opposite direction, as is known, for example, from cable ties. The receptacle can have an elastically deflectable hook that fixes the mounting element in the opposite direction to the insertion. To release the mounting element, the elastically deflectable hook can be manually deflected.

[0025] In one embodiment, the receptacle is offset from the clip section towards the inside of the frame, so that it overlaps the opening created by the clamping frame. In this case, a longer insertion path is possible, and the clamping frame can overlap the frame by a larger section. Alternatively, the receptacle can be offset from the clip section in such a way that the mounting element moves towards the clip section when it is inserted into the receptacle.

[0026] The mounting is specifically aligned orthogonally to an opening created by the clamping frame. The insertion direction for the mounting element is therefore also orthogonal to the plane created by the clamping frame.

[0027] The fastening element has at least one first clip-on section with which the fastening element can be attached to a frame strut by clipping it on.

[0028] The clip-on section extends, in particular, along the frame strut in a strip-like form, and its cross-section features a variable head area that is elastically deformed or deflected during clipping. The clip-on section is specifically omega-shaped (Ω) in cross-section, meaning it has two flat legs in its base area connected by an arc-shaped section. At least one of these legs is elastically deflected during clipping by the elastic deformation of the arc-shaped section. With appropriate design, such a clip-on section can be clipped onto or into a projection or channel.

[0029] In one embodiment, the fastening element has exactly a single, linearly extending clip section with which the fastening element can be attached to a frame strut. The strip-shaped section extends over a maximum of 10% of the length of the frame strut.

[0030] In an alternative embodiment, the fastening element may have a first, linearly extending clip section and a second clip section extending orthogonally to the first clip section, so that the fastening element can be attached in a corner area of ​​the tension frame to both a first frame strut and an adjacent second frame strut.

[0031] In this context, it is particularly possible that the first clip section is connected to the second clip section via a hinge mechanism. The fastening element can therefore initially be attached to, for example, a projection of a first frame member using the first clip section, which is preferably aligned with an adapter profile strip. Subsequently, the second clip section is pivoted relative to the first clip section via the hinge mechanism, so that the second clip section is clipped to a clamping element on the second frame member. The design of the second clip section can differ from that of the first clip section, so that, for example, the second clip section can be clipped onto a projection of the second frame member. Such a fastening element is even more securely attached to the tension frame.

[0032] The net is primarily an insect screen, but can also be designed as a pollen screen or another grid-like structure.

[0033] The clamping element can be designed, for example, as a keder or as a clamping strip made of plastic.

[0034] The invention and its technical context are explained below using the figures as examples. They show schematic representations. Figure 1: a first embodiment of an attachment device, Figure 2: the attachment device according to Figure 1 Figure 3: a fastening element of a second embodiment of an attachment device, Figure 4: the second embodiment during attachment to a tension frame and Figure 5: the second embodiment in a state attached to a tension frame.

[0035] The in Figure 1The illustrated mounting device 6 comprises a fastening element 6.1 and an L-shaped mounting element 6.2 designed as a suspension element. The fastening element 6.1 has a first clip section 6.1bi extending in a strip-like shape with an omega-shaped (Ω) cross-sectional design. A receptacle 6.1a is connected to the first clip section 6.1bi, which is designed such that the mounting element 6.2 can be inserted into the receptacle 6.1a. The mounting element 6.2 can be inserted into the receptacle 6.1a in one insertion direction and is fixed in the opposite direction of insertion by an elastically deflectable hook. To release the mounting element 6.2, the elastically deflectable hook must therefore be manually deflected. The mounting device 6 can be attached to a clamping frame 1 by means of its first clip section 6.1bi.

[0036] The one in the Figure 2The tension frame 1, partially shown in Figures 4 and 5, has a first frame strut 2 and a second frame strut 3, the second frame strut 3 being orthogonal to the first frame strut 2. Together, the first frame strut 2 and the second frame strut 3 define a plane. The tension frame 1 is designed as a telescopic frame, for which the first frame strut 2 comprises an outer profile strip 2.2 and an inner profile strip 2.1 that can be telescopically inserted into the outer profile strip 2.2. The second frame strut 3 also has an outer profile strip 3.2 and an inner profile strip 3.1 that can be telescopically inserted into the outer profile strip 3.2. The profile strips of adjacent frame struts 2 and 3 are each connected to one another by a connector 4 designed as a corner connector. The connector 4 has concealed legs that are inserted into the profile strips.

[0037] The profile strips 2.1, 2.2, 3.1 and 3.2 each have projections extending along their direction of extension as part of a clamping design 7. An adapter profile strip 9 is attached to the projections of the inner profile strips 2.1 and 3.1 as part of the clamping design 7, the outer contour of which corresponds to the outer contour of the projections of the outer profile strips 2.2 and 3.2.

[0038] To define a net not shown in the figures, a clamping element 5 designed as a clamping strip is attached to the contour of the clamping design 7 formed by the projections of the outer profile strips 2.2 and 3.2 and the adapter profile strip 9.

[0039] At the in Figure 2In the illustrated embodiment, the first clip section 6.1bi of the mounting device 6 is clipped onto the projection of the inner profile strip 2.1, with an adapter profile strip 9 also clipped onto the projection of the inner profile strip 2.1 on both sides. The clamping strip 5 is then clipped onto the two adapter profile strips 9 and the first clip section 6.1bi to secure the mesh (not shown). The frame, thus equipped with several mounting devices 6, can be attached to a window frame by means of the mounting elements 6.2, which are designed as hanging elements.

[0040] The in Figure 3 The embodiment of the fastening element 6.1 shown differs from the one in Figure 1The illustrated fastening element is characterized by the fact that, in addition to the first clip-on section 6.1bi, it has a second clip-on section 6.1bii, which carries the receptacle 6.1a. The second clip-on section 6.1bii is connected to the first clip-on section 6.1bi via a film hinge 7.

[0041] As from Figure 4 As can be seen, the fastening element 6.1 is first clipped onto a projection of the inner profile strip 3.1 using the first clipping section 6.1bi, with an adapter profile strip 9 also clipped onto the projection. Subsequently, the second clipping section 6.1bii is clipped onto the projection of the outer profile strip 2.2.

[0042] Out of Figure 5It can then be seen that a clamping strip 5 has been clipped onto the adapter profile strip 9, which is clipped onto the projection of the inner profile strip 3.1. This clamping strip 5 is aligned with the fastening element 6.1, while another clamping strip 5 is clipped directly onto the projection of the outer profile strip 2.2, which in turn is aligned with the fastening element 6.1. The receptacle 6.1a is thus offset in the corner area of ​​the tension frame 1 in the direction of the opening created by the tension frame 1. This allows for a large overlap of the tension frame 1 with the window frame in both the horizontal and vertical directions when the tension frame 1 is attached to a window using the mounting element 6.2, which is designed as a hanging element.
