Description

The invention relates to a frame system for a particle guard according to the preamble of claims 1 and 12 and a spring bracket according to claim 16. Such a frame system is for example from DE 10 2006 005 610 A1 known. In this case, particulate protection grids are understood to mean, in particular, an insect protection or pollen protection grille.

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 simplest possible assembly and disassembly of the frame system on a window opening to the window outside limiting Rahmenfalzkante a window frame is desirable.

For non-destructive hanging of the frame system on a window opening to the window outside limiting Rahmenfalzkante executed as a mounting bracket suspension straps can be firmly connected to the frame system. For this purpose, the upper mounting bracket may have a greater leg length than the lower mounting bracket. Due to the different length of the upper and lower mounting bracket, the frame system can be switched on and off due to the upper sliding clearance to the window frame of the window.

From the EP 1 433 920 A2 is an insect protection device with an insect repellent spanning support frame known which can be hung by means there as a corner angle spring angle in the frame of a window. The respective spring angle is slidably held in a specially trained U-shaped receiving guide a frame leg of the support frame and is fixed in its mounting position by means of a clamping screw which is screwed against the insect protection fabric facing U-legs of the receiving guide. The spring angle of the frame outside and inside frame of the support frame forth freely visible in its relatively large, one-sided fully open receiving guide only partially, so that the support frame intentionally provided for optical reasons for mounting within the frame and the spring angle are constructed.

From the DE 198 35 390 A1 is an insect protection device with a composite of hollow profile strips clamping frame for an insect screen known, being mounted to hang on a window opening limiting frame flashover of a window frame in the upper corner regions of the clamping frame in each case a spring angle to the clamping frame. The spring angle has a sliding body, which is guided elastically displaceable in a guide chamber of the vertical hollow profile strips and firmly connected to an upper suspension lug. The slider is supported by a helical compression spring on a counter-retaining piece, which also rests in the guide chamber of the hollow profile strip. The counter-retaining piece is supported on an end edge of a vertical slot introduced into the wall of the guide chamber at the upper end section of the hollow profiled strip. Due to this required support function of the vertical slot on the one hand, the mounting position of the spring angle is fixed to the hollow profile strip. On the other hand, the hollow profile can not be flexibly cut to adapt to different sized window opening. In addition, the vertical slot for receiving and for the required accessibility of the slider and / or the counter-holding piece is designed to be wide and therefore must be covered by means of a molded onto the slider plate-shaped attachment part.

The invention has for its object to provide a frame system of insect, pollen or particle protection grid with a flexible and simple as possible spring angle, which allows a simple and reliable mounting and unmounting of the frame system in or out of a window frame. In addition, a corresponding spring angle should be specified.

This object is achieved by a frame system with the features of claim 1. Advantageous embodiments and further developments are the subject of the dependent claims.

For this purpose, a frame system for an insect, pollen or particle protection grille is provided with a number of hollow profile strips mounted perpendicularly to each other in frame corner regions, which are designed for attachment of a mesh fabric on the frame side. In the frame corner areas, a number of assembly and spring angles for nondestructive attachment to a window outer-side Rahmenfalzkante a window frame are provided on the inner side facing the window frame inside.

The hollow profile strips have an almost completely closed guide chamber, in that a guide slot introduced into the latter in the longitudinal direction of the strip and running along the hollow profile strip is dimensioned so narrow that the guide slot has guide straps on both sides flank. These guide plates are used for guiding and clamping fixation of the respective spring angle. For this purpose, this has a clamping body and a sliding body, which is displaceable relative to the force of a compression spring relative to the clamping body. The slider carries an angle bracket, which engages behind the Rahmenfalzkante a window frame in the suspended state of the frame system.

In the installed state, the clamping body is located in the guide chamber and is displaceable along its guide plates in the strip longitudinal direction. The clamping body has a pair of longitudinal rails, along the longitudinal rails of which is also in the guide chamber sliding body against the spring force displaced. For this purpose, the clamping body on the guide slot of the functional chamber by cross-guide web and guide on both sides of the guide bar, wherein in the longitudinal direction extending guide grooves engage the guide plates. Due to the shape of the guide chamber and the clamping body inserted therein, forces acting on the frame system can be easily and safely absorbed.

The clamping body can thus be moved along the hollow profile strip practically over the entire profile length in a designated or desired mounting position and then clamped to the guide plates. For this purpose, in the region of a screw opening for a clamping screw in the guide web, a clamping slot passing through this is introduced, so that the hollow profile-side guide straps are clamped between the groove walls of the clamping body-side guide grooves as a result of a twisting of the clamping screw.

Suitably, sliding body on the clamp body push-movable, but held captive. For this purpose, a tongue and groove connection between the longitudinal rails of the clamping body and the slider is provided, advantageously integrally formed on the slider sliding cam in the outside inserted in the longitudinal rails sliding grooves einliegen and there engage behind the respective groove side wall.

For the sliding mobility of the slider of the spring angle along the guide lugs of the hollow profile are preferably also on both sides of the guide slot of the function chamber sweeping sliding web of the slider introduced into this running in strip longitudinal slide grooves in which the guide plates of the guide chamber are performed.

To limit the displacement of the slider along the clamp body forms this at the transition to the longitudinal rail pair a stop. Another stop on the rail free end of the longitudinal rail pair is made of a suitably integrally formed on the clamp body stop collar. The preferably slidably guided on the clamp body and held captive on this slider is thus displaceable along the longitudinal rail pair only between the two clamp body side stops against the spring force of the compression spring.

The compression spring is therefore expediently between the longitudinal rails of the longitudinal rail pair in the clamp body. For this purpose, the longitudinal rail pair is suitably formed by U-limbs extending in the direction of the guide slot of the hollow profiled strip and of a U-shaped receiving channel formed on the clamping body for the compression spring. The U-legs wear in this embodiment advantageously the longitudinal grooves for the tongue and groove connection between the slider and the clamping body.

In an advantageous embodiment, the slider on a projecting between the longitudinal rails of the clamping body bearing pin on which the compression spring is supported. Is also a handling cam with the interposition of the angle bracket of the spring angle connected to the slider, so the spring angle can be manually operated, d. H. manually moved to mount or unmount the frame system. As a result, in a suspension operation, the spring angle can be lowered in a simple manner by a manual compression of the compression spring.

For a suspension mounting of the frame system of an insect, pollen or particle protection grid on a window opening to the window outside limiting Rahmenfalzkante a window frame is therefore provided a spring angle, consisting of an assembly with only a few highly functional components, namely the clamping body and the slider with it attached Angle bracket and the clamped therebetween, preferably designed as a helical compression spring spring element consists. The clamping body is easily inserted into a hollow profile strip of the frame system of the hollow profile end side ago. To the clamping body, which as well as the sliding body suitably made of plastic and therefore can be produced as an injection molded part, the longitudinal rail pair is formed, along the longitudinal rails of the sliding body against the force of the inset between the longitudinal rails compression spring is displaceable.

The angle lug expediently has a fork-shaped longitudinal limb with a longitudinal slot open on the front side. Thus, the angle bracket subsequently, ie in the Hollow profile strip already pushed-in assembly of clamping and sliding body pushed therebetween compression spring on the slider pushed and clamped it. This allows a comparatively simple, safe and less bulky transport of the frame system with already integrated spring bracket assembly, but still without angle bracket, which would otherwise protrude beyond the respective hollow profile strip of the frame system and therefore damaged, z. B. could be bent.

The above object is also achieved according to the invention by a frame system having the features of claim 12. Advantageous embodiments and further developments are the subject of the dependent claims.

For this purpose, in turn, a frame system for an insect, pollen or particle protection grid is provided with a number of hollow profile strips mounted in frame corner regions perpendicular to each other, which are designed for a frame-side attachment of a mesh fabric. In the Rahmeneckbereichen several mounting and spring bracket for non-destructive hanging on a window outer side Rahmenfalzkante a window frame are provided on the inner side facing the window frame.

The hollow profile strips have also in this variant, an almost completely closed guide chamber by an inserted into this longitudinally bar and along the hollow profile strip extending guide slot is dimensioned so narrow that flank the guide slot on both sides guide plates. These guide plates also serve to guide the respective spring angle. For this purpose, however, this has means for producing a frictional connection in the form of a meander-like form spring and a slider coupled thereto, which is connected to the angle of the Rahmenfalzkante of the window frame engaging behind.

The sliding body projects beyond the guide slot into the guide chamber and is guided by the guide lugs of the guide chamber. The meander-like form spring passes through the sliding body in such a way that the shaped spring is frictionally supported as a result of the spring preload in the guide chamber and there in particular on its chamber bottom. The spring ends of the form spring are guided over the guide slot and through the angle bracket outwardly such that, as a result of manual actuation of the spring ends, the frictional engagement between the form spring and the guide chamber is achieved.

In an advantageous development of this variant, the shaped spring has a number of U-shaped bent spring legs with corresponding, approximately semicircular leg arcs. The spring legs having the spring ends are pivotable against each other with the frictional engagement causing leg arches, while the spring legs or leg arches extending therebetween bear against a supporting contour of the slider. Preferably, the spring ends of the form spring are guided in handling cam, which engage over the guide slot with the interposition of the angle bracket and against the spring force of the form spring against each other, d. H. to be displaced on each other. As a result, the frictional engagement in the guide chamber is released, so that guided in the guide slot sliding body can be manually moved along with the angle of this held angle bracket in the strip longitudinal direction of the hollow profile and locked again in any position.

For a Einhängebsteigung the frame system of an insect, pollen or particle protection grid on a window opening to the window outside limiting Rahmenfalzkante a window frame is provided with this variant another frictional lockable spring angle, in turn, from an assembly with only a few highly functional components, namely the Slider with attached angle bracket and the meander-shaped spring element. The meandering shaped spring, which is coupled to produce a releasable frictional engagement in a guide chamber of the hollow profile strip with the sliding body, suitably consists of spring steel, while the sliding body is preferably made of a plastic.

In the case of a suspension operation, in both variants the angle tabs, for example the upper spring angle, are initially clamped in a position in which the horizontal legs of the angle tabs are located below the upper frame edge of the frame system. The angle brackets of the lower mounting bracket are moved over the lower stop edge on the frame and then lowered the frame system until the lower angle brackets sit with their horizontal webs on the edge of the lower Blendrahmenfalzkante. The frame system is aligned and finally the upper angle brackets are pushed upwards until the upper horizontal webs abut the edge of the Blendrahmenfalzkante. This eliminates an additional step in which the angle bracket must be fixed by tightening a clamping screw, which advantageously shortens and facilitates the hanging process.

Finally, the object is achieved by a spring angle with the features according to claim 16.

Embodiments of the invention will be explained in more detail with reference to a drawing. Show:

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

This in 1 illustrated frame system 1 is made of two vertical hollow profile strips 2a and two horizontal hollow profile strips 2 B ( 3 to 5 ), which are interconnected in corner areas. In the frame system 1 is a protective grid or mesh fabric 3 , For example, as insect protection, clamped. The frame system 1 is about two lower mounting brackets 4 and two upper spring angles 5 in a window frame 6 Clamp-mounted to the window inside. The mounting bracket 4 and the spring angle 5 engage behind a Rahmenfalzkante 7 of the window frame 6 , The mounting bracket 4 can also in the upper and the spring angle 5 in the lower corners of the frame system 1 be arranged. Also in the four corners only spring angle 5 be provided.

As in 2 can be seen, the at the lower end of the respective vertical hollow profile 2a arranged mounting bracket 4 an angle bracket 8th and one in the hollow profile strip 2a inserted nut-like retaining element 9 on, on which the angle lug 8th by means of two clamping screws 10 frame fixed is clamp fixed. The holding element 9 lies in a leadership chamber ( 6 ) of the hollow profile strip 2a a positive fit. The angle bracket 8th has a running in strip longitudinal L locking slot 11 on, through which the clamping screws 10 through in internal threaded holes of the retaining element 9 are guided. When tightening the clamping screws 10 becomes the retaining element 9 against the inner wall and the angle bracket 8th against the outer wall of the hollow profile strip 2a pressed so that the mounting bracket 4 frame fixed is clamp fixed.

In 2 is a fixation stone 12 recognizable, which is also in the hollow profile strip 2a rests and screw fixing with the horizontal hollow profile strip 2 B serves. A cap 13 closes the vertical hollow profile side in the corner area 2a at the front side.

The in 2 in cross-section and in the 3 and 6 to 8th in an enlarged perspective view shown spring angle 5 is as a contiguous assembly of a clamp body 14 and a slider 15 and a compression spring clamped in between 16 built up. This module with the clamp body 14 and the slider 15 and the compression spring 16 is in the hollow profile strip 2a and there in the from the front 17 from accessible leadership chamber 18 pushed in, in 6 is relatively clear. Also in this corner of the frame system 1 is again a fixation stone 12 in the hollow profile strip 2 for screw fixing with the associated horizontal hollow profile strip 2 B used. Another cap 13 also closes the vertical hollow profile strip in this corner area 2a at the local front side 17 , The slider 15 the spring angle 5 in turn carries an angle strap 19 , analogous to the angle bracket 8th of the mounting bracket 4 approximately Z-shaped and this suitably bent at right angles to the rear handle on the Rahmenfalzkante 7 of the window frame 6 manufacture.

How out 6 it can be seen, is the guide chamber 18 the hollow profile strip 2a almost completely closed, taking on the window frame 6 facing mounting or inside of the hollow profile strip 2a only a narrow guide slot 20 is introduced. The guide slot 20 is thus on both sides of guide plates 21a and 21b the leadership chamber 18 flanked. The leadership chamber 18 is rectangular or square in cross section. The guide slot 20 runs on the outside of the profile 22 opposite profile inside 23 and is preferably located centrally between the two guide tabs 21a . 21b , The guide slot 20 extends - as well as the leadership chamber 18 - In strip longitudinal direction L over the entire length of the hollow profile strip 2a , Preferably, the cross-sectional profile of the vertical and horizontal hollow profile strips 2a and 2 B same, but may be different.

The guide straps 21a . 21b the hollow profile strip 2a or its guide chamber 18 form guide or slide rails for both the clamp body 14 as well as for the slider 15 , the angle lug 19 wearing.

Like from the 7 and 8th is comparatively clear, the clamping body 14 a clamping head 14a and a molded on this leadership 14b on. The clamping head 14a and thus the clamp body 14 has two sides of a guide bar 14c in strip longitudinal direction L extending guide grooves 14d and 14e on. With the guide bar 14c passes through the clamp body 14 or its clamping head 4a the guide slot 20 the hollow profile strip 2a , At the same time grip the guide plates 21a and 21b in the corresponding guide grooves 14d respectively. 14e of the clamp body 14 one.

Analog has the slider 15 the spring angle 5 one the guide slot 20 the functional chamber 18 sweeping sliding bridge 15a on, in turn, on both sides of extending in strip longitudinal direction L Gleitnuten 15b and 15c flanked. In the sliding grooves 15b and 15c in turn are the guide tabs 21a respectively. 21b the functional chamber 18 the hollow profile strip 2a guided.

The leadership 14b of the clamp body 14 is approximately U-shaped in cross section and forms a longitudinal rail pair 24 , Along the longitudinal rails 24a and 24b is the slider 15 slidable in longitudinal strip L. In the longitudinal rails 24a and 24b are sliding grooves 25 introduced, of which in the 7 and 8th only in the longitudinal rail 24a introduced sliding groove 25 is recognizable. In these grooves 25 grab the slider 15 molded sliding cams 26 one, so that between the longitudinal rail pair 24 of the clamp body 14 and the slider 15 a practically insoluble push-movable tongue and groove connection is created.

The to the clamping head 14a of the clamp body 14 molded U-shaped guide shaft 14b forms a receiving channel 27 between the longitudinal rails 24a and 24b , In this recording channel 27 of the clamp body 14 is the compression spring 16 one. This is supported on the one hand on the clamping head 14a of the clamp body 14 and on the other hand on a trunnion 28 off, attached to the slider 15 is formed and between the longitudinal rails 24a . 24b in the receiving channel 27 of the clamp body 14 protrudes.

As a result of the tongue and groove connection 25 . 26 between the slider 15 and the clamp body 14 with in its receiving channel 27 enclosed compression spring 16 is the in 7 illustrated assembly (assembly) with virtually captive parts 14 to 16 provided. This is in this form in the leadership chamber 18 the hollow profile strip 2a from the front side 17 insertable here and there on the guide plates 21a and 21b both with the clamp body 14 as well as with the slider 15 guided. The executed as this unit spring angle 5 may be due to the in Listenlängsrichtung L over the entire length of Hohlrpofileiste 2a extending guide slot 20 as well as also over the entire length of Hohlrpofileiste 2a extending guide chamber 18 to any position of the hollow profile strip 2a be pushed.

To the slider 15 at the leadership 14b and thus on the clamp body 14 To keep captive and a slipping of the clamp body 15 from the longitudinal rail pair 24 is to prevent this, ie to the longitudinal legs 24a . 24b of the clamp body 14 free end a stop collar 29 formed. As a result of the spring preload of the compression spring 16 lies the slider 15 with its with the longitudinal rail pair 24 corresponding guide rail pair 30 , the inside the sliding cams 26 wears, on the stop collar 29 of the clamp body 14 and is supported there. The stop collar 29 limits the running in strip longitudinal direction L adjustment of the slider 15 ,

In the in 6 shown target position of the spring angle 5 this is done by means of the clamp body 14 on the guide straps 21a and 21b of the guide channel 18 clamp fixed. For this purpose, a clamping screw is used 31 that the clamping head 14a via a screw hole 32 interspersed and in an underlying inner bore 33 of the clamp body 14 is screwed in. The jamming is achieved by a guide bar 14c of the clamping head 14a in the area of the screw opening 32 enforcing clamping slot 34 , In the installed state according to 6 Aligns the clamping slot 34 with the guide slot 20 the hollow profile strip 2a , so when tightening the clamping screw 31 the guide grooves 14d and 14e of the clamping head 14a narrowed and the in the guide grooves 14d respectively. 14e positively locking guide plates 21a . 21b the leadership chamber 18 be clamped under formation of a force or friction fit.

The angle bracket 19 the spring angle 5 will suitably only later, after the from the clamp body 14 , the slider 15 and the compression spring 16 existing assembly in the guide chamber 18 inserted and there by means of the clamping screw 31 has been fixed in place with the sliding body 15 connected. This is a correspondingly preassembled frame system 1 easily and non-destructively be brought to the mounting location, without the risk that, for example, the angle bracket 19 is bent. The angle bracket 19 is therefore - as in 8th shown - with a frontally open longitudinal slot 19c Mistake. This is a fork-shaped longitudinal leg 19a formed, of which the L-shaped clamping angle 19b the angle lug 19 bent at right angles. The fork-shaped longitudinal leg 19c engages positively and frictionally in longitudinal grooves 15d one in the slider 15 are formed. Thus, the angle bracket 19 im in the 6 and 7 Montageendzustand shown on the slider 15 clamp fixed.

The in the 4 such as 9 and 10 shown embodiment of the spring angle 5 is different from the one after the 3 and 6 to 8th in principle only in that between the clamping body 14 and the slider 15 no practically insoluble tongue and groove connection is provided. This spring angle 5 is therefore relatively simple, with the captivity of the components 14 to 16 This unit is given as soon as this in the management chamber 18 the hollow profile strip 2a is inserted. In this mounting state slides on the guide plates 21a . 21b the hollow profile strip 2a guided sliding body 15 under bias of the compression spring 16 slidingly movable relative to the clamp-fixed clamping body 14 , The adjustment of the slider 15 is in turn limited by the clamping head 14a and the rail free end stop collar 29 of the clamp body 14 , Analogous to the embodiment according to the 3 and 6 to 8th determines the length of the guide shaft 14b again the length of the adjustment of the slider 15 in lengthwise direction L.

To the slider 15 the spring angle 5 this embodiment according to the 9 and 10 is a handling cam 35 formed. This allows a comparatively simple manual displacement of the slider 15 in the longitudinal direction L to the angle bracket 19 against the force of the compression spring 16 to shift and thereby the angle bracket 19 from their joining position behind the Rahmenfalzkante 7 of the window frame 6 to release into a free position, leaving the frame system 1 from the window frame 6 can be removed. Such a handling cam 35 can also on the slider 15 in the 3 and 6 to 8th illustrated spring angle 5 be provided.

The 5 such as 11 and 12 show a variant of a spring angle 5 with a meander-shaped curved spring 36 as friction element. The approximately m or w-shaped shape spring 36 lies in the assembled state in one in the guide chamber 18 the hollow profile strip 2a guided sliding body 37 one. Here, the two outer leg arches dominate 36a and 36b and the middle leg arch 36c the slider 37 to the chamber floor 38 the leadership chamber 18 out. Only the two outer thigh bows 36a and 36b the shape spring 36 lie in the in 11 shown position frictionally on the bottom of the chamber 38 on, during the middle leg arch 36c the shape spring 36 to the chamber floor 38 is spaced.

The bent spring ends 36d and 36e the shape spring 36 are over the guide slot 20 the leadership chamber 18 and by the - here preferably closed - longitudinal slot 19c in the angle bracket 19 to the outside and there in each case a handling cam 39 respectively. 40 guided. The lower leg arches 36a to 36c opposite upper leg arches 36f and 36g the shape spring 36 lie in the slider 37 on a corresponding support contour 41 respectively. 42 at. This support contour 41 . 42 can be attached to a slider part 37a be provided when the slider 37 - as in 12 shown - is executed in two parts. In this case, in the final assembly state, the two Gleitkörperteile 37a . 37b of the slider 37 positively and / or non-positively connected. The slider 37 or its sliding body part 37b also has a support contour 43 . 44 on, at the two outer, the spring ends 39 . 40 supporting spring legs 36h respectively. 36i abut and support themselves there.

Due to the support contours 41 to 44 of the slider 37 become when squeezing the spring ends 36d and 36e in the in 11 illustrated force direction F, the two outer spring legs 36h and 36i pivoted inward so that the two outer leg arcs 36a and 36b the shape spring 36 from the bottom of the chamber 38 the leadership chamber 18 at least slightly lift off and the frictional engagement is released. In this holding position of the spring ends 39 and 40 the shape spring 36 is the spring angle 5 ' in strip length L along the hollow profile strip 2a slidable and can be guided to the desired mounting position. There, the frictional connection can be made again by the force on the spring ends 36d and 36e over the handling cam 39 respectively. 40 is lifted and the outer spring legs 36h and 36i again in their in the 5 such as 11 and 12 swing back home position shown in consequence of the spring force of the form spring.

The inward movement of the handling cams 39 . 40 as a result of the force in the direction of force F is limited by roof-like inclined to each other Anlageschrägen 45 . 46 on the handling cam 39 respectively. 40 and one through the guide slot 20 the leadership chamber 18 and through the longitudinal slot 38 the angle lug 19 Outwardly guided frustoconical system 47 of the slider 37 , This prevents that as a result of the force in the direction of force F of the middle leg arc 36c undesirably against the bottom of the chamber 38 the leadership chamber 38 is guided and there produces an unwanted frictional engagement in the actual release position.

The invention is not limited to the embodiments described above. On the contrary, 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, furthermore, all individual features described in connection with the various exemplary embodiments can also be combined with one another in other ways, without departing from the subject matter of the invention.
