Description

DESCRIPTION

The invention relates to a functional frame with a hook-like suspension element to be detachably fastened to construction-side frame segments of doors, gates or windows, wherein the connection between the construction-side frame segment and functional frame can be established with the hook-like suspension element, and wherein the hook-like suspension element exhibits a flexible tab. In particular, the invention relates to a functional frame, such as an insect protective frame, which can be permanently, detachably fastened to construction-side frame segments of a varying frame thickness and composition.

Retaining devices with latching mechanisms are known from various fields of application, and predominantly exhibit only a visual similarity to the device according to the invention. Devices that are of a similar type or principally identical are known from various devices available in the respective trade for fastening insect protective frames to construction-side frame segments. These devices are essentially bracket elements made out of metal, which are rated for varying construction-side frame thicknesses in varying sizes, and essentially screwed to the insect protective frame or parts of the insect protective frame. However, the disadvantage here is that a plurality of different brackets must be fabricated and provided, and that, in most cases, boreholes must be introduced into the frame profiles or into parts of the insect protective frame. When the insect protective frame is later separated from the construction-side frame segment, these boreholes are inevitably left behind, and have to be resealed again, potentially with a high outlay.

Likewise known are fastenings for insect protective frames that are fabricated out of spring steel wire, are bent in a wide variety of ways, and can be joined with the insect protective frame in a wide variety of ways. As relates to the system, such spring steel straps are screwed to the insect protective frame, or suspended or clamped in openings or channels or the like provided for this purpose. However, the disadvantage here is that such a spring steel material exhibits a limited life, and the retaining force tapers accordingly. Likewise, the retaining force is slightly impaired by an improper overstretching. As a result, only conditional use can be made of such systems in the do-it-yourself area. A two-part fastening device with latching mechanism is known from DE 10 2004 002 573. Provided here is an S-shaped component, in which a functional frame can be suspended by latching or by pressing into a frame profile fabricated for this purpose. This component is equipped with a receiving chamber, into which an angular retaining element is inserted. Both parts are joined together by a complementary latching mechanism or a toothed system. However, the disadvantage here is that the angular retaining element can only be inserted to a limited extent, making any adjustment to a construction-side frame thickness extremely complicated. Also disadvantageous is the necessary dimensioning of the receiving chamber for the angular retaining element. For example, a closed casement comes to abut in the area of this receiving chamber, and consideration must be given to impediments to correct window closure or damage to the sash gasket.

Another fastening device with toothed system or latching mechanism is known from DE 699 03 680 T2. An arced, toothed retaining bracket is here guided through the body of the frame connector. The arced retaining bracket is twisted correspondingly deeply through a transport screw, comparable to a gear mechanism with rack, as a result of which the insect protective frame is clamped to the construction-side frame element. However, the disadvantage here is the very high mechanical outlay, along with the associated comparatively high production costs. Also disadvantageous is that an overlapping retaining strap is situated parallel to the window frame only in one achievable position owing to the arced movement of the retaining bracket, thereby creating a rather significant pressing point to the window frame in all other positions. This may give rise to damage to the window frame or seals .

Additional known fastening devices for insect protective frames come predominantly from specific, custom-made specialist retailer products, and are technically complex and expensive, which precludes application or use in the inexpensive do-it-yourself area. A functional frame with the features mentioned at the outset is known from DE 20 2007 009 166 Ul.

Therefore, the object of the invention is to create a functional frame for preferably detachably fastening to construction-side frame segments of doors, gates or windows, which can be flexibly used for a plurality of varying thicknesses of construction-side frame segments, and is easy to handle.

This object is achieved according to the invention by a functional frame with the features in claim 1. Advantageous embodiments of the invention are defined in the dependent claims .

The construction-side frame segment is detachably fastened with the fastenable functional frame by means of at least one hook-like suspension element, which passes through the functional frame and engages the frame segment from behind. The hook shape of the suspension element limits an insertion of the suspension element through the functional frame, and at least one section of the suspension element abuts against a contact surface of the frame segment after pushed through. The flexible tab of the suspension element then makes it possible to create a preferably detachable fastening between the frame segment and functional frame by bending the flexible tab so that it engages the frame segment from behind, thereby establishing a form-fitting connection between the hook element and functional frame on the one hand, and between the frame segment and hook segment on the other.

This yields a system that can easily be used in the do-it-yourself area, is highly flexible due to the bending of a flexible tab of the suspension element that takes place during the fastening process, and can potentially be used for a construction-side frame segment or functional frame of any thickness. Any protruding lengths of the suspension element are bent away, and parts thereof cut out as needed.

It is especially preferred that an insertion channel be provided on the construction-side frame segment, into which the suspension element can be inserted. It is further preferred that a complementarily shaped opening also be provided in the functional frame. This results in an especially simple and reliable connection in the system according to the invention without the end user having to do any additional preparatory work.

The step of bending away the flexible tab of the suspension element is supported by the selection of suitable materials, with sheet steel being the material of choice given its strength and flexibility. At especially large sheet thicknesses and/or an especially high strength of the material, it is further recommended that at least one predetermined bending point be introduced into the flexible tab of the suspension element, so that bending can hereby also be done by hand, without the use of a tool being required.

It is especially preferred that such a predetermined bending point be provided in the form of one or more openings, such as a boreholes in the flexible tab. In particular a sequence of a plurality of round boreholes or perforations arranged in series relative to each other yields a suspension element, which can easily and continuously be bent away along a plurality of defined predetermined bending points.

In an alternative embodiment of the invention that is likewise especially preferred, however, the flexible tab of the suspension element incorporates an oblong hole whose longitudinal extension coincides with the longitudinal axis of the flexible tab or is at least arranged parallel. This yields a suspension element that allows a bending precisely at the desired location on the flexible tab without the formation of individual predetermined bending points, preferably by hand. This is further achieved with especially simple means.

The materials and dimensions for the flexible tab should be selected in such a way that the flexible tab can be bent away by hand, with the suspension element then still having the inherent rigidity and dimensional stability advantageous for the inventive purpose.

Another preferred embodiment of the invention provides an additional covering cap, which covers the flexible tab that adjoins the functional frame after bending, in particular fixing it in this position. This not only advantageously supports the optics of the entire system, since the covering cap advantageously also serves to fix in place at a defined distance from the construction-side frame segment the part of the suspension element into which the functional frame can later be suspended. This blocks any displacement by the suspension element, so that a readjustment of the suspension element by hand can be avoided with especially simple and reliable means, even while suspending the functional frame.

Likewise preferred is an embodiment of the invention in which the functional frame consists of at least four side rails and four corner elements, wherein the corner elements and side rails are designed with plug-type connections. It is very especially preferred that the openings or insertion channels for the suspension elements be formed in the corner connectors. This not only provides a highly flexible configuration for the functional frame, the height and/or length of which can be easily changed by replacing individual side rails; in addition, a functional frame is created in which the connection with the construction-side frame segment via the suspension elements can be established exclusively using corner elements and without any influence of the side rails whatsoever. Further preferred here is an embodiment in which the openings for the suspension elements are provided in the corner elements.

Several exemplary embodiments of the invention will be described in greater detail below with reference to the attached drawings .

Fig. 1 shows a commercially available insect protective frame, comprised of four hollow profile strips 20a to 20d, which are connected with each other by four corner connectors 21a to 21d to yield a rectangular functional frame 20, which is covered with a scrim 30 by means of pressed-in weather strips (not shown). To improve handling, such functional frames 20 are as a rule provided with two or more handles 31, 32, which can be fastened to the functional frame 20 in different ways. Such insect protective frames have long constituted prior art in a variety of configurations.

Fig. 2 shows the basic structural design of such functional frames 20, wherein profile strips 20a to 20d are cut to a desired length, put together by means of corner elements 21a to 21d, and connected with a scrim 30 via corresponding weather strips 40a, 40b. Such functional frames 20 are functionally secured to the outside of a window frame or construction-side frame segment 50, as depicted on Fig. 3 and 4, and serve as insect protection. Various fastening means are offered for attachment to the window frame, which are predominantly conceived based on the configuration of the respective product and shape of the respective profile. These fastening means are essentially angular or hook-shaped in design, and predominately made out of flat metal or spring steel wire. These fastening brackets or fastening hooks are joined with the insect protective fame or parts thereof predominantly via screwing or clamping at different positions, so that the covering film 20 is suspended on the window frame or on other construction-side frame segments.

According to the object cited at the outset, a fastening system exemplarily shown on Fig. 5 and 6 is created for such functional frames, in particular such plug-type frame systems. For this purpose, the system according to the invention uses an angular suspension element 3, which can be continuously inserted into a through borehole (not shown) inside of the corner element 21 until it hits the suspension element 5' on the window frame 50. As shown on Fig. 5a) and b) , the insect protective frame 20 can be comfortably suspended in the window rabbet by slightly pushing in the suspension element 5. After suspended in this way, the suspension element 5 is pushed into the corner element 21 in the direction of the arrow until the insect protective frame 20 tightly adjoins the window rabbet, as depicted on Fig. 6a) and b) . Bending away the flexible tab 5' , more precisely the portion of the flexible tab 5' as depicted on Fig. 6b) [that] passed through the corner element 21, then establishes a form-fitting and potentially also a force-fitting connection between the functional frame 20 and construction-side frame segment 50.

The system according to the invention is here conceived in such a way as to establish a complementary, mechanical connection between the functional frame and suspension element, as a result of which the angular suspension element is blocked in the opposite direction during insertion in the direction of the arrow and bending away of the flexible tab 5' . Manually releasing this bend makes it possible to again pull out the suspension element, and remove the functional frame from the window. In a preferred embodiment of the invention, all four corner elements 21a to 21d are equipped according to the depicted cutout in order to reliably and correctly fasten a functional frame, for example an insect protective frame. In this way, an embodiment of the system according to the invention can be used to comfortably, advantageously and detachably fasten insect protective frames to window frames or other construction-side frame segments with a varying configuration and rabbet thickness.

As a consequence, a system according to the invention preferably consists of an arrangement in particular of at least two parts, as exemplarily depicted on Fig. 7. These are a corner element 21 on the one hand, which is equipped with insertion channels 4a and 4b and a tab web 5, and a suspension element 3 on the other. In this first embodiment, the insertion channels 4a, 4b essentially consist of an angular opening 4 (in the direction of the Y-axis of the coordinate symbol) through the corner element 21. This opening 4 is centrally positioned in such a way that one leg of the angled shape points toward the Z-axis, and the second leg toward the X-axis. Situated in the diagonal, symmetrical center (Z-X axis) of the opening 4 is a diagonally lying web 5, which divides the opening into two insertion channels or insertion chambers 4a and 4b that are mirror identical to this diagonal central axis. In keeping with the function of the system according to the invention, the suspension element 3 is designed in such a way that it can be plugged into both insertion channels 4a, 4b in a form-fitting manner.

In a first embodiment, the suspension element 3 is essentially angular in design. One leg is here preferably shaped like an essentially rectangular plate, which serves as a supporting or clamping lug 3' . The second leg 3" is essentially rod-like, flat and preferably has form-fitting cross sectional design relative to the insertion channels 4a and 4b. Two outer surfaces 3"’ bordering the shape of the flexible tab are here inclined at an angle of preferably 45°.

As shown on Fig. 8a) and 8b), the suspension element 3 is shaped in such a way that it can be plugged into the insertion channels 4a and 4b in a form-fitting manner. An identical corner element 2 can thus be used on the right or left or top or bottom. As a result, an insect protective frame kit can contain four identical corner elements 2 and four identical suspension elements 3. This yields a fully functional system for fastening an insect protective frame as a functional frame, such as an insect protective frame on construction-side frame segments, with which the functional frame can be reliably and detachably fastened to the desired location.

Fig. 9 once again presents a perspective view of a suspension element 5 introduced into a corner connector 21 through an insertion channel 4. The insertion channel 4 exhibits an essentially rectangular cross section, which is complementary in design to the flat profile of the flexible tab 5' of the suspension element 5. In terms of the invention, the suspension element 5 is introduced into the insertion channel 4 until there is a defined distance between the front side of the corner element 21 and the suspension tab 5' of the suspension element 5. This defined distance preferably corresponds exactly to the width of the construction-side frame segment in which the functional frame is to be suspended using the suspension element 5. In this position, the part of the flexible tab 5' that has already passed through the through hole 4 can be bent up or down, for example by 90°, so that it can thereby come to lie adjacent to the functional frame or at least parts thereof in a form-fitting manner.

Fig. 10 presents a perspective rear view of a system according to the invention that corresponds to the front view from Fig. 9. As depicted, the part of the flexible tab 5' that has already passed through the through hole is bent downwardly away by 80° to thereby yield a form-fitting connection between the flexible tab 5' and corner element 21. In this position, the distance between the corner element 21 and stop element 5" of the suspension element 5' can at the very least not get any larger. In order to completely fix the suspension element in this position, a covering cap 6 is additionally provided, which is joined with the corner element 21 in such a way that the bent flexible tab 5' permanently retains its form-fitting connection with the corner element 21 of the functional frame. This reliably prevents the suspension element 5 from becoming displaced in both the direction toward the covering cap 6 and away from the latter. In addition, it is especially preferred that a rabbet into which the flexible tab 5' of the suspension element 5 can be placed be provided in the corner element 21 as depicted or complementarily in the interior side of the covering cap 6.
