Description

The invention relates to a frame system for a mesh fabric (insect and / or pollen guards) as insect and / or pollen protection, with a number of each profile profile having longitudinal profiles and cross sections, which are mounted or mounted in Rahmeneckbereichen by means of corner joints perpendicular to each other, and with a cooperating with the respective corner connector retaining clip with a spring leg, which protrudes in the assembled state of one of the profile contours.

To protect housing openings, such as window or door openings (balcony or patio doors), serve as a frame mountable insect, particle or pollen guards, which are used in a profile frame, which in turn should cover the building opening as fully as possible. Here, the most flexible adaptation to different opening sizes is desirable.

One from the EP 1 596 034 B1 Known frame system already allows both an unproblematic frame assembly and a simple insertion of the protective grid or fabric in the profile frame. In addition, a disassembly is possible, in particular to replace individual parts. Furthermore, a secure mounting of the covered with the protective mesh fabric (grid or cloth) profile frame at the destination, in particular a window or on a window frame, guaranteed.

The rails of the known frame system are designed as hollow chamber profiles with a window frame open towards the receiving channel, the Recording of a welt for attachment of the grid, a mesh fabric or a pollen protection fabric is used. The grid or tissue covers the frame opening of the lattice frame and thus the window opening against ingress of foreign particles permeable to air.

In the known frame system, one-piece and right-angled corner connectors are used for connecting the longitudinal and transverse profiles. Their joining legs are designed such that they can be positively inserted into corresponding receiving chambers of the profile formed as a hollow profile front and side frictionally. In the joint legs introduced recesses take on one of the legs of a retaining clip, the other leg serves as a spring leg for non-destructive and detachable mounting of the frame system on a building-fixed frame, in particular on a window frame, the building opening to be protected.

The invention has for its object to improve a frame system of the type mentioned, in particular with respect to one hand, the corner joint and on the other hand, the holder on a building opening or its building frame, preferably on a window frame. In particular, a simple to assemble, stable and as flat as possible to build frame system should be specified. Furthermore, a suitable corner connector or a suitable corner connector arrangement and a retaining clip for this purpose should be specified

With respect to the frame system, the object with the features of claim 1 and with respect to the corner connector or the corner connector assembly with the features of claim 9 and with respect to the retaining clip with the features of claim 10 is achieved according to the invention. Advantageous embodiments and further developments are the subject of the dependent claims.

The frame system is designed for the preferably detachable mounting of an insect and / or pollen protection grid (mesh fabric) and has a number of longitudinal profiles and transverse profiles, which in the frame corners by means of below Also referred to as corner connector assembly corner or profile connectors are connected in pairs. The corner connector has an angle element and at least one sliding block with an internal thread (internally threaded bore). The angle element comprises two mutually perpendicular joining feet with at least one passage opening, wherein for a reliable holding preferably each of the joining legs suitably has two passage openings.

In the assembled state of the respective corner connector passes through a screw which is part of the corner connector, with the screw shank, which preferably carries a metric external thread, the through hole of the joining element of the angle element and is screwed to the sliding block, d. H. screwed into its internal thread. In this case, the sliding block lies in the profile contour of the respective longitudinal or transverse profile of the frame system, wherein the retaining clip is arranged in regions between the joining leg and the sliding block.

The respective profile has a profile contour, which is also referred to below as a profile inner contour, for receiving the respective sliding block. The profile contour forms a suitably three-sided closed and on the fourth side, which represents the profile back, partially open receiving chamber for the or each sliding block. The rear opening area of the receiving chamber or profile contour can be round, oval or slot-like. Preferably, however, the rear opening is a extending over the entire profile length longitudinal slot, so that regardless of where along the profile of this is cut to provide the desired profile length, for the screw always a back access into the receiving chamber of the profile contour and there to Internal thread of the sliding block consists.

In the assembled state, the screw is guided normal to the rear profile plane over the longitudinal slot to the sliding block and bolted to its internal thread. In this case, the sliding block is preferably displaceable in a pre-assembly state in the profile longitudinal direction and in particular against rotation in the profile contour, ie in the receiving chamber formed thereby. The sliding block is preferably rectangular in cross-section, suitably square. As a result, the sliding block can be easily inserted into the receiving chamber of the respective profile formed by the profile contour and displaced therein.

Expediently, the profile contour has joining shoulders on the inside, against which the sliding block groove in the receiving chamber of the profile contour of the respective profile is supported. The joining shoulders extend on the inside of the profile contour or receiving chamber along the longitudinal slot and flank it on both sides.

According to a suitable embodiment, the profile contour or the receiving chamber formed by this is sized to receive both the or each sliding block and that portion of the retaining clip, which portion suitably forms a clip leg, which in the assembled state between the joining leg and the or each of these joining leg the angle element associated with sliding block is arranged. In the assembly stand, therefore, there is only the angle element of the corner connector on the back and thus outside, d. H. einliegen on the rear outer side of the respective profile, while the or each sliding block and the clamping leg of the retaining clip within the profile contour or receiving chamber.

In a particularly advantageous development of the longitudinal and / or transverse profile, a support shoulder is formed on the outside facing away from the receiving chamber in the profile longitudinal direction and the longitudinal slot whose shoulder height extending normal or perpendicular to the rear profile plane is preferably equal to or only slightly greater than the thickness the angle element of the corner connector. As a result, this aligned in the assembled state with the free end of the support shoulder, so that it is not surmounted by the angle element. The flat-fitting corner connector arrangement therefore leads to a particularly flat frame construction with a virtually invisible from the frame outside insertion structure for the angle element and thus for the corner joint as a whole.

In an expedient embodiment, the spring leg and the clip leg of the retaining clip merge with one another to form a double-bent bending point. The clip leg of the retaining clip suitably has two leg sections which are curved parallel to one another to form at least one plug-in eye. Preferably, the retaining clip has two so-formed eyelets, which ensures a sufficiently stable mounting of the corner connector. In a pre- and final assembly state, these eyelets are aligned with the longitudinal slot of the profile contour and with the internal thread of the respective sliding block, so that the screw or its threaded shank can be easily and reliably screwed into the internal thread via the longitudinal slot and the respective eyelet.

The leg of the angle element of the corner connector narrowing side and thus frontally superior spring leg of the profile contour or receiving chamber area or partially inserted retaining clip protrudes in the assembled state on the longitudinal slot of the respective profile contour or receiving chamber and is manually operable on the profile back, d , H. the spring leg can be bent on the frame back against the elastic restoring force. As a result, a non-destructive mounting of the frame system on a fixed frame, in particular on a window frame, a building opening allows. In this case, both the angle element and the retaining spring or clip or its clamping legs are clamped by means of the same screw on the respective profile and thus frame back on the frame system.

The corner connector or the corner connector arrangement for an insect screen frame system comprises an angle element and a sliding block having an internal thread and a retaining clip held between the latter and a joining leg of the angle element by means of a screw connection, which projects beyond the joining leg of the angle element in a freewheeling or frontal manner.

The retaining clip comprises a spring leg and a clip leg, which is integrally connected to the spring leg via a bent bending point. With In other words, the spring leg and the clip leg of the retaining clip are suitably integrally connected to form at least one bending point, preferably two bending points. The clamping leg has two leg sections, which extend parallel to each other, forming at least one plug-in eye.

The angle element of the corner connector may be a plastic part, but is expediently designed as a stamped part of a sheet metal or strand material. Likewise, the sliding block is preferably made of metal, for example aluminum. The retaining clip is preferably made of spring steel.

According to a variant of the corner connector, the corresponding joining leg has at least approximately parallel and spaced apart leg layers, between which a receiving longitudinal space extending in the receiving space is formed, in which the retaining clip rests with a staple leg and clamped there in the assembled state and thus integrated into the corner connector , The receiving space (receiving chamber) is suitably open at the two side limbs and at one of the corners of the corner connector facing narrow side. In addition, preferably one of the leg layers of the respective joining gusset of the corner connector is arranged so as to be elastically bendable such that a free end of this elastic leg layer can be pivoted into the receiving space.

A particularly suitable profile for an insect protection frame system has a profile contour for receiving a corner connector and an overlapping edge extending in the profile longitudinal direction, which projects beyond the profile contour in the profile transverse direction. The profile contour facing profile edge rear side of the overlap edge serves as a profile contact surface and thereby as a support surface or edge in the manner of an abutment on a building frame, in particular on a window frame.

A constructed of such profiles (longitudinal and transverse profiles) insect screen frame is particularly suitable for building or window frame, where at closed, typically in the building opening opening building or window sash outside (circumferential) Rahmenfalz remains in which the profile rests or einliegen with the profile contour for receiving the corner connector and possibly further profile contours for sealing brushes or the like forming profile base body. The overlapping edge then lies flat in the assembled state on the frame outside of the building or window frame and thus practically forms the counterpoint for a, for example, with retaining clips on the building frame releasably secured insect protection frame system.

Corresponding parts are provided in all figures with the same reference numerals.

The Fig. 1 and 2 show in front and rear view fragmentary mounted as an insect or pollen window frame system 1 of longitudinal profiles 2 and cross sections 3, of which in each case a profile 2, 3 are mounted perpendicular to each other in the frame corner shown. For this purpose, each adapted to the desired window dimension of a building window opening (horizontally extending) transverse profile 3 and each one (vertically extending) longitudinal profile 2 by means of a corner connector 4 according to the details explained in more detail stable in the four frame corner releasably connected. The below also referred to as a profile strip profiles 2, 3 are preferably made of aluminum, but may also be designed as plastic profiles.

With regard to the front side of the profile (frame front side) 5a opposite, in the final assembled state facing the window frame back 5b is at the transverse and longitudinal profiles 2, 3 hereinafter referred to as mesh fabric 6 insect or pollen guards to provide insect protection, a pollen shield or general particle protection mounted. The attachment of the mesh fabric 6 by means of flexible, in particular rubber-elastic retaining elements in the form of preferably Kederleisten 7. These are - as in FIG. 5 it can be seen - slotted receiving chambers 8 of the profile strips 2, 3 in the profile or frame back in the profile longitudinal direction L pressed in during assembly.

Like from the FIGS. 4 and 7 is comparatively clearly visible, the respective profile strip 2, 3 a profile contour 9. This forms a extending in the profile longitudinal direction L receiving chamber which is closed on three sides and on the profile rear side (frame back) 5b via a profilrückseitig introduced into the profiles 2, 3 longitudinal slot 10 is accessible. The profile contour 9 and thus the receiving chamber formed by this extends parallel to the receiving chamber 8 and is used in the embodiment of the corner connector 4 according to the representations of the Figures 5 and 6 for receiving and holding of sliding blocks 11 with below as internal thread 12 ( Fig. 6 ) designated threaded hole.

The longitudinal slot 10 of the profile strip 2, 3 forms joining or support shoulders 13, which are formed on the longitudinal slot 10 in the profile longitudinal direction L flanking profile webs 14 of the profile contour 9 inside. As a result, the corresponding receiving chamber is closed profile-wise in the profile transverse direction Q areawise or in sections, as well as area-wise or section-wise open and thus accessible.

The corner connector 4, also referred to below as a corner connector arrangement, in the embodiment according to FIGS Figures 5 and 6 a right-angled angle element 4a with mutually perpendicular Fügeschenkeln 4b and the sliding blocks 11 with their internal thread or internal threaded bore 12. In the Fügeschenkel 4b through holes 15 are introduced, which are interspersed in the assembled state of fixing screws 16 with metric threaded shaft.

Im in Fig. 3 in the partial mounting state shown corner portion of the frame system 1 are within the respective profile contour or receiving chamber 9 displaceable in the profile longitudinal direction L sliding blocks 11 at their intended Guided position in which their internal thread 12 are aligned with the passage openings 15 of the angle element 4a. It is already, preferably both in the longitudinal profile 2 and in the transverse profile 3, within the corresponding profile contour 9 and receiving chamber, a retaining clip 17th

The retaining clip 17 has a clip or clamping leg 17a and a spring leg 17b. With this spring leg 17b, the retaining clip 17 is partially in the profile contour 9 and receiving chamber, while the spring leg 17b of the retaining clip 16 via the longitudinal slot 10 of the profile contour 9 profile or frame back led out. The spring leg 17b is thus manually from the frame back side 5b ago out of the frame plane resiliently elastically to produce a corresponding spring restoring force aufbiegbar.

Fig. 5 shows the corner connector or the corner connector assembly 4 in the assembled state in which the angle element 4a by means of screws 16 with the interposition of the clamping leg 17a of the retaining clip 17 with the or each sliding block 11 is screwed. Fig. 6 shows in perspective exploded view, the corner connector assembly 4 with the angle element 4a and two sliding blocks 11 and with the retaining clip 17 and the fixing screws sixteenth

A transition region between the clamping leg 17a and the spring leg 17b of the retaining clip 16, referred to hereinafter as the bending point 17c, is double-cranked. This bend is carried out in such a way that the spring leg 17b of the retaining spring or clip 17 rests against the respective profile strip 2, 3 at the rear or protrudes slightly towards the free end thereof. Freiendseitig the spring leg 17b of the retaining spring 17 is bent at right angles to form an angle tab 17d in the embodiment. The angle tab 17d serves on the one hand for manual bending of the spring leg 17b of the retaining clip 17 transversely to the profile longitudinal and transverse profile L and Q and on the other hand as a rear handle a Rahmenfalz the stationary frame of a building opening.

In the assembled state, the respective fixing screws 16 on the shank side pass through the passage openings 15 of the joining legs 4b of the angle element 4a as well For this purpose, the clamping leg 17a of the retaining clip 17 has two to form the eyelets 18 parallel to each other curved leg portions 19a, 19b on the longitudinal slot 10 and aligned with the corresponding passage opening 15. While the leg portion 19b passes over the bending point 17c in the spring leg 17b, the other leg portion 19a along the clamping leg 17a preferably ends at least slightly behind the plug-in eye 18 of the bending point 17c.

The retaining clip 17 is designed in the embodiment as a round wire, preferably as a spring wheel with a circular cross-section. Alternatively, the retaining clip 17 can also be designed as a spring plate with punched openings for forming the eyelets 18 n.

How out Fig. 5 is comparatively clear, are in the assembled state, the sliding blocks 11 and the respective clamping leg 17a of the retaining clip 17 within the receiving chamber formed by the profile contour 9. In this case, the clamping leg 17a of the retaining clip 17 is arranged between the respective sliding block 11 and the angle element 4a. In this arrangement, the clamping leg 17a is supported at least in the region of the eyelets 18 directly on the inside joining or support shoulders 13 of the profile contour 9 on both sides of the longitudinal slot 10 from. In the screwed state of the fixing screws 17, the respective sliding block 11 is supported on the clamping leg 17a of the retaining clip 17 also on these joining or support shoulders 13 of the profile contour 9 on both sides of the longitudinal slot 10.

The clamping action of the clamping leg 16a of the retaining clip 16 is suitably achieved in that the screw shank of the respective fixing screws 15 is supported on the profile or chamber bottom 20 of the profile contour 9 or receiving chamber. As a result, as a result of the screw the sliding blocks 11 to produce the desired clamping fixation of the clamping legs 17a of the respective retaining clip 17 in the direction of the joint shoulders 13 of the profile contour 9 guided and braced against them with the interposition of the clamping leg 17a.

Like from the 4 and 5 it can be seen, a support shoulder 21 is formed on the back of the respective profile or the respective profile strip 2, 3 and the outside of the profile contour 9 in the profile longitudinal direction L. Which are perpendicular to the rear profile plane extending shoulder height h ( Fig. 4 ) is dimensioned to the thickness d ( Fig. 5 ) of the angle element 4a adapted that this does not project beyond the support shoulder 21 profile and frame back.

By means of the corner connector assembly 4 on the one hand and the configuration of the profiles or profile strips 2, 3 on the other hand, in particular in the region of their profile contour 9, - seen in the direction normal (perpendicular) to the plane defined by the profile longitudinal and transverse profile L or Q frame plane LQ - a particularly thin overall structure with simultaneous reliable fixation of the profiles 2, 3 in the Rahmeneckbereichen and thus a particularly flat frame system 1 for an insect or pollen guards 6 is provided.

Im in Fig. 2 shown mounting state of the corner connector assembly 4 project beyond the spring legs 17b of the retaining clips 17, the joining leg 4b of the angle element 4a frontally, ie at the corner region 4c of the angle element 4a facing away from the leg ends. In the area of the angle corner 4c, the angle element 4a suitably has a further passage opening 15 for a further fixing screw 17. This nut corresponds with another nut 11 with internal thread 12. This nut 11 is also displaceable in the profile contour or receiving camera 9 of the two profiles, in the embodiment of the cross profile 3. By means of this nut block 11 and the associated fixing screw 17 is a decorative cap or - plate 22 on the transverse profile 3 and thus releasably attached to the frame system 1.

The FIGS. 7 to 9 show a variant of the corner connector 4. As out Fig. 7 it can be seen, the profile contour 9 of the profile strip 2, 3 serves in turn for receiving and holding one of the two joining legs 4b of the respective corner connector. 4

For this purpose, the longitudinal slot 10 of the profile contour (receiving chamber) 9 flanking joining shoulders 13 are overlapped in the assembled state shown by a leg position 23b of Füverschels 4b of the corner connector 4 and with a spaced therefrom leg position 23a of the Fügurt 4b (within the receiving chamber 9) behind.

With the corner connector 4, in turn, two retaining clips 17 are suitably joined, which are clamp-fixed between the leg positions 23a, 23b of the respective joining sleeve 4b. By means of fixing or clamping screws 24, also referred to as screwing, a clamp-fixing joint connection of the retaining clip 17 with the respective joining leg 4b takes place during assembly and at the same time a clamp-fixing joint connection of the corner connector 4 with the corresponding profile strip 2, 3.

Fig. 8 shows the pre-assembled with the retaining clips 17 by means of fixing screws 24 corner connector 4. This is in Fig. 9 also shown in perspective view without retaining clips.

Between the mutually parallel and spaced extending leg layers 23a, 23b of the respective Fügeschenkels 4b of the corner connector 4, a receiving space or a receiving chamber 25 for receiving the respective retaining clip 17 is formed. The distance between the two leg layers 23a, 23b of the respective joining sleeve is adapted to the size or thickness of the respective retaining clip 17 in such a way that it can be introduced easily into the receiving space 25.

While the merging into each other leg position 23b of the two Fügeschenkel 4b of the corner connector 4 in the corner region of the corner connector 4 materially, that is integrally connected to each other end the spaced leg position 23a of the joining legs with their free ends 26a in leg longitudinal direction in front of this corner of the corner connector 4 and parallel Leg position 23b spaced. The opposite thigh free 26b the Thigh layers 23a, 23b are in turn cohesively, that is preferably integrally connected.

In the region of these leg-free ends 26b, the respective joining leg 4b has a passage opening 27. About these passage openings 27 of the spring leg 17b of the retaining clip 17 is led out of the receiving space 25 between the leg positions 23a, 23b of the Fügurt 4b and thus from the corner connector 4 frontally. The one-piece with the spring leg 17b, due to the clamped with and thereby in the corner connector 4 joint connection as clamping leg 17a designated staple leg of the retaining spring 17 is in the assembled state ( FIGS. 7 and 8 ) in the receiving space 25 of the respective joining gift 4a, 4b.

The transition region (bending point) 17c between the clamping leg 17a and the spring leg 17b of the retaining clip 17 is double cranked, so that the spring leg 17b of the retaining spring or clip 17 abuts the rear side of the respective profile strip 2, 3 or protrudes slightly on the free end side. The freiendseitig angle tab 17d serves on the one hand for manual bending of the spring leg 17b of the retaining clip 17 transversely to the profile longitudinal direction L and on the other hand as a rear handle a Rahmenfalz the stationary frame of the building opening.

In the one-piece connected leg layers 23b of the corner connector 4 through holes 27 are introduced, which are aligned with corresponding screw holes 28 of the parallel spaced leg position 23a. About the through holes 27, the glands, that is, the corresponding fixing screws 24 inserted on the shaft side and screwed into the screw holes 28 of the opposite leg position 23a. In the assembled state, the screws 24 enforce the plug-in eyelets 18, which are aligned on the shank side with the passage openings 27 of the joining legs 4b, of the respective retaining clip 17.

As in particular from the FIGS. 4 and 6 can be seen, the profile strip 2, 3 on a Überdeckungs- or overlapping edge 29. This extends to the profile front 5a in profile transverse direction Q on the receiving back on the profile 5b receiving chambers 8 and 9 and a further receiving chamber 30 for a (not shown) sealing brush or the like sealing element and serves in the assembled state as abutment or abutment surface of the frame system 1 at a corresponding frame edge 31 of a building frame 32, in particular a window frame. Here, the particularly narrow structure of the respective profile strip 2, 3 is particularly advantageous adapted to the rebate width b of the building frame 32. The corresponding dimension, ie the total thickness or profile depth a of the profile strip 2, 3 results from the height c of the chambers 8, 9, 30 plus the shoulder height h and the thickness of the profile material, which corresponds to the edge thickness g of the overlap edge 29.

In other words, the profile thickness (a-g) of the profiled strips 2, 3 extending perpendicularly to the profile planes LQ and to the frame plane of the frame system 1 is dimensioned on their profile back side 5b smaller than or equal to the rebate width b of the building frame 32. The frame system 1 can thus with the profile rear contour or chamber structure of the receiving chambers 8, 9, 30 einliegen in the throat opening or the corresponding Rahmenfalzkante of the building frame 32 (window frame) and with the overlap edges 29 at the corresponding fold region of the frame edge 31 up or . issue. In conjunction with the frame inside the adjacent retaining clips 17, the frame outer side overlap edge 29 thus acts as a counterhold of the frame system. 1

The invention is not limited to the embodiments described above. Rather, other variants of the invention can be derived therefrom by the person skilled in the art without departing from the subject matter of the invention. In particular, all the individual features described in connection with the exemplary embodiments can also be combined with one another in other ways, without departing from the subject matter of the invention.

Thus, the configuration of the profiled strip 2, 3 with a profile contour 9, in particular for receiving a corner connector, as well as with an extending in the profile longitudinal direction L overlap edge 29, which the profile contour 9 in the profile transverse direction L projects beyond, and whose the profile contour 9 facing profile edge rear side as a profile contact surface 33 (FIG. Fig. 7 ) on a building frame 32, in particular on a frame edge 31 of a window frame, is used, in particular independently of the corner connector used, regarded as an independent invention.
