WINDOW WITH A PROTECTIVE DEVICE AND KIT FOR THE PROTECTIVE DEVICE

Description

[0001] The present invention relates to a window with a frame, a window sash pivotably mounted on the frame and having a sash frame, and a protective device, wherein the protective device comprises several frame struts, a net, and several plastic clamping elements for fixing the net to the frame struts, wherein the frame struts have a fixing contour extending along their longitudinal extent, and wherein the clamping elements have a clamping contour extending along their longitudinal extent, wherein the clamping contour of the clamping elements and the fixing contour of the frame struts are aligned such that the net can be fixed to the frame struts by means of the clamping elements.

[0002] From EP 3 138 990 B1, which originates from the applicant, a protective device is known, in which the frame members each have at least one outer profile strip and an inner profile strip that can be telescopically inserted into the outer profile strip, so that the size of the frame can be easily adjusted to the size of the window. The profile strips have a fixing contour, referred to as an (auxiliary) projection, to which the net can be attached by means of a clamping strip. In order for the net to be fixed with a single clamping strip per frame member, an adapter profile strip is clamped onto the auxiliary projection of the inner profile strip. The frame members are connected to each other via corner connectors to form a tension frame. To ensure that the tension frame has sufficient stability, the profile strips are made of aluminum.These tension frames are typically attached to the window frame from the outside using L-shaped mounting elements, with an overlapping section of the mounting elements extending at least partially over the window frame. The tension frame of the protective device is dimensioned so that it overlaps the window frame at least partially. To prevent insects or pollen from passing between the window frame and the tension frame, a (brush) seal is usually installed in the overlap area between the two. To attach the brush seal to the tension frame, the frame members of the tension frame have grooves extending along their longitudinal axis, in addition to the fixing contour offset towards the inside of the frame. The seal is positioned in these grooves.Such a protective device is relatively expensive to manufacture due to its aluminum frame struts. Furthermore, it requires a certain amount of space on the outside of the window.

[0003] From EP 2 484 855 B1, another protective device with frame struts is known, which are connected to each other via corner connectors. A hanging element can be inserted into the corner connectors, with which the protective device is hung on a window frame. A protective device with the features of the preamble of claim 1 is known from DE 20 2013 103720 U1.

[0004] The object of the present invention is to eliminate the disadvantages described with reference to the prior art and in particular to provide a window with a protective device and a kit for a protective device in which the manufacture of the protective device is advantageous and which do not require any space on the outside of the frame.

[0005] The problem is solved by a window and a kit with the features of the corresponding independent claim. Advantageous embodiments of the window and the kit 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 way.

[0006] The problem is solved by a window with the aforementioned features, in which the frame mullions each have plastic profile strips. These profile strips, apart from the fixing contour extending along their longitudinal extent, have no further functional contours. The profile strips are glued to the frame, and when the window is closed, the profile strips, with the clamping elements attached to them, are positioned between the frame and the sash. The mesh thus fixed by the profile strips and the clamping elements on all four sides of the window completely covers the building opening defined by the frame. The adhesive bond also prevents insects / pollen from entering between the mesh and the frame.

[0007] Accordingly, a kit for a protective device for such a window comprises a net, several plastic profile strips, wherein the profile strips have no further functional contour in addition to a fixing contour extending along their longitudinal extent, adhesive for attaching the profile strips to a window frame, and several plastic clamping elements for fixing the net to the profile strips, wherein the clamping elements have a clamping contour extending along their longitudinal extent, wherein the clamping contour of the clamping elements and the fixing contour of the profile strips are coordinated in such a way that the net can be fixed to the fixing contour with the clamping elements.

[0008] The basic idea of ​​the invention is that the frame struts spanning the net (for example, an insect screen or pollen screen) across the opening defined by the window frame consist of inexpensively manufactured plastic profile strips and are glued directly to the window frame, for example, using double-sided adhesive tape. The profile strips are glued to the window frame at such a point that, when the window is closed, the profile strips and the attached clamping elements are located within a space defined by the window frame and the sash frame. Since very little space is available in this area of ​​the window, the profile strip has no further functional features besides its fastening element. Rather, the side of the profile strip opposite the fastening element simply has a surface for gluing the profile strip to the window frame.The profile strips and the clamping elements, also made of plastic, are dimensioned so that they can be positioned in the corresponding space between the frame and the window sash. The protective device is therefore inexpensive to manufacture and easy to install, eliminating the need to connect frame members directly to each other using corner connectors.

[0009] To mount the protective device, the profile strips and clamping elements can first be cut to the required length, adapted to the window size. The clamping elements preferably have the same length as the corresponding profile strips. The profile strips can then be attached to at least three sides of the window using adhesive (double-sided tape). In a preferred embodiment of the protective device installation, the mesh is attached to another profile strip using a clamping element, and this profile strip is only then glued to the window frame. The mesh is then secured to the profile strips already glued to the window frame using the remaining clamping elements. Finally, only the portion of the mesh extending beyond the profile strips / clamping elements needs to be trimmed.

[0010] In one embodiment, the fixing contour is designed as a channel extending along the longitudinal axis with a slot extending along the longitudinal axis, through which the clamping elements can be inserted into the profile strip. The area of ​​the profile strip that defines the slot thus forms a kind of undercut, which is engaged by the clamping elements.

[0011] The clamping elements can be formed, for example, by means of a keder, i.e., in particular by a suitably dimensioned rubber tube. Alternatively, the clamping elements can be designed as clamping strips, the clamping strips preferably having an omega-shaped (Ω) cross-section. In the latter case, the strip is also referred to as an omega strip. Such an omega strip has an approximately uniform thickness throughout its cross-section, with the cross-sectional design featuring two parallel, aligned legs at its ends, which are connected to each other by an arc-shaped section. The arc-shaped section is thus inserted into the fixing contour of the profile strip orthogonally to the plane spanned by the profile strips, whereby the omega strip, and in particular its arc-shaped section, is elastically deformed during insertion.

[0012] Alternatively, the profile strip glued to the frame can also be designed as an omega strip, in which case the legs are attached to the frame, in particular by means of a double-sided adhesive tape. Accordingly, the clamping strip would have a corresponding cross-sectional design that allows it to be attached to the curved section of the omega strip.

[0013] In order to be able to be installed in the space limited by the frame and the window sash frame, the profile strip with the clamping element attached to it has a height of a maximum of 2 cm, preferably a maximum of 1 cm and a width of a maximum of 3 cm, preferably a maximum of 2 cm or even more preferably a maximum of 1 cm.

[0014] The maximum width of the profile strip (in a cross-sectional view) is at most 20%, preferably at most 10% wider than the width of the defining contour.

[0015] In one embodiment, each frame strut can comprise at least two telescopically slidable profile strips. Thus, the frame strut can be shortened not only by cutting off a profile strip, but also by extending the profile strips relative to each other. In particular, if the profile strips are designed as omega strips, two profile strips with identical cross-sections can also be arranged telescopically relative to each other by partially fitting the profile strips onto one another and moving them along their longitudinal axis.

[0016] According to the invention, it is provided that the frame struts (i.e. the profile strip(s)) which are adjacent via a corner of the frame are connected to each other via a soft hinge with several degrees of freedom, in particular if the profile strips of a frame strut are telescopic relative to each other.

[0017] Such a soft hinge can, for example, be formed using heat-shrink tubing, so that the adjacent profile strips are connected to each other but remain movable / pivotable. In particular, if all frame members are connected to their respective adjacent members via a soft hinge, the profile strips can be arranged in a starting position parallel to each other. By pivoting the profile strips of a frame member relative to each other, they can be moved into an assembly position in which the profile strips are arranged at right angles to each other in a frame plane. In such an assembly position, the frame can be adjusted to the size of the window by telescoping, after which the profile strips are glued to the frame. The mesh can then be secured using the clamping strips.

[0018] The invention and its technical context are explained below using the figures as examples. They show schematic representations. Figure 1: an open window with a protective device, Figure 2: a sectional view through the closed window, Figure 3: a detailed view of the sectional view according to Figure 2 Figure 4: a profile strip and a clamping element fixed to the profile strip, Figure 5: two profile strips, each with a clamping element defining a net, and Figure 6: a profile strip with a further embodiment of a clamping element.

[0019] The window 4 shown in the figure in an open state comprises a frame 5 and a window sash 6 pivotally mounted on the frame 5 with a window sash frame 6.1 carrying a window pane.

[0020] A protective device 7 is attached to the window 4, the mesh 3 of which covers the opening limited by the frame 5.

[0021] The protective device 7 comprises profile strips 1 to which the net 3 can be fixed by means of clamping elements 2.

[0022] As in Figure 2 indicated and in Figure 3 In detail, the profile strip 1 and the clamping element 2 are arranged in an area which, when the window is closed, is bounded by the window sash frame 6.1 and the frame 5. The profile strip 1 is attached to the frame 5 using double-sided adhesive tape, and the clamping strip 2 is attached / clipped onto the profile strip 1 to secure the mesh 3.

[0023] The in the Figures 4 and 5 The profile strip 1 shown in detail has a channel extending along the longitudinal extent of the profile strip 1 as a fixing contour 1.1, wherein the channel has a longitudinally extending gap on a top side into which the clamping element 2 is clipped.

[0024] The in the Figures 4 and 5The clamping element 2 shown is designed as an omega strip with an omega-shaped (Ω) cross-section. The omega strip has a constant cross-sectional thickness and two legs connected by an arc-shaped section. The omega strip, with its arc-shaped section forming the clamping contour 2.1, is inserted into the channel of the profile strip 1.

[0025] As in the Figure 5 As indicated, the protective device 7 comprises several profile strips 1, in each of which a net 3 is fixed by means of a clamping element 2.

[0026] In an embodiment not shown, the omega strip could also be glued to the frame 5 of the window 4 as a profile strip, whereby the profile strip 1 shown in the figures could be attached to the omega strip as a clamping element for fixing the net 3.

[0027] At the in Figure 6In the illustrated embodiment, the clamping element 2 is designed as a keder which is inserted into the channel of the profile strip 1. Reference symbol list
