Description

[0001] The present invention relates to a protective device for a building opening, in particular an insect screen, the frame of which comprises at least one profile strip and can preferably be arranged in a cavity between a frame and a sash of a window. The invention further relates to a kit for such a protective device, a method for manufacturing a protective device, and a window with a corresponding protective device.

[0002] The frame of such an (insect) screen typically comprises four frame members, with adjacent frame members arranged at right angles to each other. Each frame member has at least one profile strip extending in a longitudinal direction, the profile strip having a fixing contour extending in the same longitudinal direction. It may be provided that each frame member has two or more telescopic profile strips, so that the frame can be adjusted to the size of a window by telescoping the profile strips of the frame members relative to each other. In an alternative embodiment, however, it may be provided that each frame member comprises only exactly one profile strip. In this case, the profile strip must be shortened to fit the size of a window.Adjacent frame struts can be connected to each other via corner connectors, so that a more or less rigid alignment of adjacent frame struts to each other is predetermined.

[0003] To secure the (insect screen or pollen screen) net, which may consist of a woven or knitted fabric, to the profile strips of the frame, at least one clamping element is provided for each profile strip, the clamping contour of which is adapted to the fixing contour of the profile strip, so that the net can be attached between the clamping contour and the fixing contour by inserting or attaching (for example, clipping) the clamping element with the clamping contour into or onto the fixing contour of the profile strip.

[0004] The profile strips and clamping elements of the protective device can be dimensioned such that the frame of the protective device can be arranged in a space formed between the frame and the sash of a window, with the mesh stretched across the window opening enclosed by the frame. The protective device can be attached to the window frame using adhesive, for example, double-sided adhesive tape.

[0005] From EP 3 910 154 A1 a protective device and a kit for a protective device with the features of the preamble of the respective independent claim are known.

[0006] In the known kit with plastic profile strips and clamping elements, tensions can be induced in the net when attaching it to the profile strip with the clamping element. After attachment, these tensions cause the profile strip and clamping element to bend inwards towards the frame, making installation on the window frame difficult. With the known kit, the net can also be cut to size before being attached to the profile strip, but there is a risk that the net will not be cut correctly. Alternatively, after attaching the net to the profile strip, a section of the net extending beyond the profile strip can be cut off. However, in this case, an edge of the net typically protrudes outwards beyond the profile strip. A protective device with the features of the preamble of claim 1 is known from EP 2 878 757 A2.

[0007] 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, a kit for a protective device and a method for manufacturing a protective device, with which the protective device is easier and safer to assemble and with which the frame of the protective device is not deformed during manufacture.

[0008] A solution to this problem is provided by the protective device, the kit, and the method with the features of the respective independent claim, wherein further solutions and advantageous embodiments are specified 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. Features and advantages described with reference to the kit are applicable to the protective device and the method for manufacturing the protective device, and vice versa.

[0009] The problem is solved by a protective device according to claim 1.

[0010] The problem is also solved by a method for manufacturing a protective device according to claim 11.

[0011] The problem is also solved by a kit for a protective device, according to claim 8.

[0012] In other words, the invention essentially provides that one (or more) pre-fixing element(s) is (or are) formed on the at least one profile strip of the frame. These pre-fixing elements allow the net to be pre-attached to the frame, so that in a subsequent manufacturing step, the net can be fully secured to the at least one profile strip using the at least one clamping element. This pre-fixing ensures that no stresses are induced in the net when it is secured with the at least one clamping element, which could later deform the at least one profile strip. The at least one pre-fixing element also allows the net, pre-fixed to the frame, to be cut to size precisely before being fully secured, as the net can no longer slip during the cutting process.

[0013] According to the invention, the at least one pre-fixing element is formed by adhesive. The adhesive is provided, in particular, by a double-sided adhesive tape which, in its initial state, is adhered to the profile strip on one side and covered by a protective film on the other. A user thus only needs to remove the protective film from the adhesive tape before pre-fixing the net to the profile strip.

[0014] In particular, the use of adhesive to pre-fix the net to the frame also makes it possible for the net to first be spread out flat (and thus without tension) on a flat surface and for the frame to then be placed on the spread-out net with a side having at least one pre-fixing element, thereby pre-fixing the net to the frame.

[0015] In a subsequent step, the net can then be cut to size and / or secured using at least one clamping element. If the frame was previously placed on the flat, spread-out net for pre-fixing, the frame only needs to be turned 180° to cut and / or secure the net, so that the net is accessible for cutting or so that the clamping elements can be attached to the profile strip.

[0016] The at least one pre-fixing element is preferably attached to the side of the at least one profile strip on which the clamping element for securing the net is / will be arranged. It can be provided, in particular, that the clamping element covers the area of ​​the profile strip containing the pre-fixing element when the net is in its fixed state.

[0017] The at least one pre-fixing element is preferably arranged exclusively relative to the fixing contour towards the opening spanned by the frame, thereby ensuring particularly effectively that the mesh is not drawn into the fixing contour when fixed by means of the clamping element. In this way, the induction of stresses in the mesh is further reduced.

[0018] To assemble the frame, the kit's profile strips can be connected using corner connectors included in the kit. In a preferred embodiment, where each frame strut has exactly one profile strip and the frame can be adapted to the size of a building opening by shortening the profile strips, four profile strips are connected using four corner connectors, with adjacent profile strips arranged at right angles to each other via their respective corner connectors. The frame, initially assembled from some of the kit's components, can then be placed on the unfolded kit mesh, as described above.

[0019] Preferably, the defining contour of a profile strip extends over the entire length of the respective profile strip.

[0020] The at least one clamping element is preferably also designed in the form of a strip and extends along a longitudinal dimension, with the clamping contour also extending along the longitudinal dimension over the entire clamping element.

[0021] In a preferred, cost-effective embodiment, both the profile strips and the clamping elements are made of a plastic.

[0022] It can be provided that exactly one clamping element or several clamping elements are provided for each profile strip. Alternatively, it can also be provided that exactly one clamping element is provided for several profile strips that together form a frame member of the frame, and that this clamping element extends over all profile strips of the frame member. In a preferred embodiment, however, it is provided that each frame member is formed by exactly one profile strip, with exactly one clamping element assigned to each profile strip. To adapt the frame to the size of a window, a user can adjust the length of the profile strip and the associated clamping element to the size of the window by cutting them to size.

[0023] The fixing contour can, for example, be formed by a channel extending along the longitudinal axis with a slot extending along the longitudinal axis, whereby the clamping element with its clamping contour can be inserted through the slot into the profile strip. The area of ​​the profile strip bounding the slot can form a kind of undercut, which is engaged by the clamping element.

[0024] In the simplest case, at least one clamping element can be formed, for example, by a keder, i.e., in particular by a suitably dimensioned rubber hose.

[0025] It is also possible for the clamping element to be designed as a clamping strip, wherein the clamping strip has at least one projecting area to form the clamping contour, which is inserted into the fixing contour of the profile strip. For example, the clamping contour can be formed by two projecting arms that are elastically deflected when attached to the profile strip and, in the net-fixing state, engage behind the undercuts on the profile strip.

[0026] Alternatively, it can also be provided that the profile strip has a head area projecting in cross-section as a fixing contour, onto which a clamping element with a corresponding receiving section can be applied.

[0027] It is preferred that the profile strip and the clamping element are fixed to each other by a type of clip connection, with the mesh being arranged at least section by section between the profile strip and the clamping element.

[0028] In a particularly preferred embodiment, the profile strip has an omega-shaped cross-section with two straight legs and a circular arc-shaped receiving section connecting the two legs to form the clamping contour. This receiving section creates a gap between the two legs, through which the clamping contour of the clamping element can be inserted. The legs, which are arranged approximately parallel to each other, are connected via the arc-shaped (receiving) section, which forms a gap between them. Such a profile strip, also known as an omega strip, is particularly easy to manufacture.

[0029] For example, a keder could be inserted into the receiving section of the omega-shaped profile strip.

[0030] Preferably, however, the clamping element has a head section corresponding to the receiving section for forming the clamping contour, which can be inserted through the gap into the receiving section of the profile strip, with a fastening section of the clamping element being arranged outside the receiving section. The fastening section can, for example, be realized by two outwardly projecting contact sections that connect to the head section outside the receiving section, the contact sections being arranged approximately parallel to the legs of the profile strip in the assembled state.

[0031] In this context, it can be provided, in particular, that the at least one pre-fixing element is arranged adjacent to the gap and, in particular, on a leg of the profile strip. The pre-fixing element is, in particular, arranged on the side of the gap that, in the assembled state of the protective device, faces inwards towards the inside of the frame with respect to the gap.

[0032] When assembled, one section of the system can be positioned so that it covers the adhesive on the profile strip. On its side facing away from the profile strip, the fastening section, or the two sections of the system, can be designed as a flat surface, so that the clamping element, and thus the entire frame, can be glued to, for example, a window frame (e.g., using double-sided adhesive tape).

[0033] The adhesive described above for pre-fixing the net to the profile strip can, in this case, for example, be applied to at least one, preferably both, legs of the profile strip.

[0034] For the production of a rectangular frame, the kit includes in particular at least four corner connectors that connect adjacent frame struts, preferably having a profile in cross-section at least on their free leg that corresponds to the outer profile of the profile strip or the clamping element, so that the corner connectors can simply be clipped onto or into adjacent profile strips.

[0035] The invention and its technical context are explained below using the figures as examples. They show schematic representations. Figure 1: a profile strip, Figure 2: a clamping element, Figure 3: a partial view of an insect screen device with the profile strip and the clamping element during manufacturing, Figure 4: the partial view of the finished insect screen device and Figure 5: a profile strip and a clamping element with the arrangement of a pre-fixing element after the manufacture of the insect screen device.

[0036] The in Figure 1The profile strip 1 shown has a fixing contour 1.1 extending along its longitudinal extent. The profile strip 1 has an omega-shaped cross-section and comprises a first leg 1.3 and a second leg 1.4, wherein the first leg 1.3 and the second leg 1.4 are connected to each other via a receiving section 1.5, so that a gap 1.2 is formed between the first leg 1.3 and the second leg 1.4. A pre-fixing element 4 in the form of a double-sided adhesive tape is attached to the profile strip 1. The double-sided adhesive tape is adhered to the first leg 1.3 and the second leg 1.4 and covers the gap 1.2. In the delivered state, a protective film is applied to the free side of the double-sided adhesive tape.

[0037] The in Figure 2The clamping element 2 shown has a clamping contour 2.1 formed by a head section 2.2, the outer cross-sectional design of which is adapted to the fixing contour 1.1 of the profile strip 1. The clamping contour 2.1 has two projecting arms which are elastically deflected inwards when inserted into the gap 1.2 of the profile strip 1 and are arranged in the receiving section 1.5 when installed. The clamping element 2 also has a first contact section 2.3 and a second contact section 2.4, which are formed integrally with the head section 2.2.

[0038] To assemble the protective device, the profile strips 1 and the clamping elements 2 are first shortened according to the window size. The profile strips 1 are then connected to each other using corner connectors (not shown). In this state, the net 3 can be placed on the legs 1.3 and 1.4 of all profile strips 1, so that the net 3 covers the gap 1.2 and is held in this aligned position by the pre-fixing element 4. This state is shown in a detailed view in Figure 3 depicted. In the Figure 3 Only one frame strut of a frame, comprising a profile strip 1 and a clamping element 2, is shown. The frame, which is not fully shown, comprises a total of 4 frame struts to which the net 3 is attached and which are connected to each other via corner connectors (not shown).

[0039] The mesh 3 and the pre-fixing element 4 are now cut by inserting a knife through the gap 1.2 on the outer side (at leg 1.4). The clamping element 2 with its head section 2.2 is then inserted through the gap 1.2 into the fixing contour 1.1, so that the mesh 3 is fixed between the profile strip 1 and the clamping element 2. The assembled protective device then needs to be installed in the window, for which purpose a double-sided adhesive strip can be applied to the outside of the clamping element 2 or the profile strip 1.

[0040] The profile strip 1 and the clamping element 2 are dimensioned so that the frame can be arranged in a cavity between a frame and a sash frame of a window, with the mesh 3 spanning the window opening.

[0041] In Figure 5It is indicated how the double-sided adhesive tape (pre-fixing element 4) is pressed against the profile strip 1 by inserting the head section 2.2 of the clamping element 2 into the receiving section 1.5 of the profile strip 1, whereby the in Figure 5 The net (not shown) is defined between the clamping element 2 and the profile strip 1.
