For this purpose, it is proposed that the flexible tongue (5 ') can be bent in a form-fitting manner against the functional frame.

Description

The invention relates to a system for releasably securing functional frames, in particular insect protection frames, to on-site frame segments of doors, gates or windows. Here, the system comprises at least one on-site frame segment and at least one with this on-site frame segment preferably releasably attachable functional frame, and a hook-like suspension element over which the connection between on-site frame segment and functional frame is effected. More particularly, the invention relates to a system for a frame connector, in particular of insect protection frames, primarily from the do-it-yourself area, with which a functional frame, such as an insect screen, permanently, redetachably attached to frame segments in different frame thickness and texture.

Holding devices with latching mechanisms are known from different fields of use and show primarily only optical similarity with the device according to the invention. Artgemäße or in principle comparable devices are known from different, available in the relevant trade devices for attachment of insect protection frame on-site frame segments. In essence, these devices are metal angle elements that are designed for different, field-wide frame thicknesses in different sizes and are essentially bolted to the insect screen frame or parts of the insect screen frame. The disadvantage here, however, that a variety of different angles must be made and provided, and that in most cases in the frame sections or parts of the insect protection frame holes must be introduced. In later re-separation of the insect screen frame from the customer's frame segment inevitably remain these holes that may need to be closed again consuming.

Likewise, fasteners for insect protection frames are known, which are made of spring steel wire and bent in various ways and can be connected in various ways with the insect screen frame. System-related such spring steel bar are screwed to the insect screen frame or hung or clamped in designated openings or channels or the like. The disadvantage here, however, is that such a spring steel material has a limited life and the holding force decreases accordingly. Likewise, the holding force is easily affected by improper overstretching. Such systems are accordingly only of limited use for the do-it-yourself sector.

A two-part fastening device with locking mechanism is known from the DE 10 2004 002 573 , In this case, an S-shaped component is provided, in which a functional frame latching or can be attached by pressing in a manufactured frame profile. This component is equipped with a receiving chamber, in which an angle-shaped retaining element is inserted. Both parts are releasably connected to each other by a complementary locking mechanism or a toothing. The disadvantage here, however, is that the angle-shaped retaining element can only be inserted to a limited extent and thus adjusting to an on-site frame thickness is extremely complicated. Likewise disadvantageous is the necessary dimensioning of the receiving chamber for the angle-shaped retaining element. In the area of this receiving chamber, for example, a closed sash comes into contact, and obstruction of the correct closing of the sash or damage to the sash seal must be taken into account.

Another fastening device with toothing or latching mechanism is from the DE 699 03 680 T2 known. Here at an arcuate, toothed bracket is passed through the body of the frame connector. The arcuate bracket is screwed by a transport screw, similar to a gear with rack, correspondingly deep and thereby clamped the insect protection frame on-site frame member. The disadvantage here, however, is the very high mechanical complexity, the associated relatively high production costs. It is also disadvantageous that due to the arcuate movement of the bracket an overarching retaining tab is only in an achievable position parallel to the window frame and thus creates a not inconsiderable pressure point to the window frame in all other positions. This can cause damage to the fixed frame or the seals.

Other known attachment devices of insect protection frames come primarily from special, custom-made specialty products, are technically complex and expensive, which precludes use or use in the low-priced do-it-yourself area.

The invention is therefore an object of the invention to provide a system for preferably releasably attaching functional frame to on-site frame segments of doors, gates or windows, which is easy to handle, is inexpensive to manufacture and also with a variety of different strengths of on-site frame segments is flexible.

This object is achieved by a system having the features of claim 1. Advantageous embodiments of the invention are defined in the dependent claims.

The system according to the invention comprises an on-site frame segment, such as a window frame or door frame and a functional frame, such as the frame of an insect screen. The preferably releasable attachment between on-site frame segment and attachable functional frame is effected by means of at least one hook-like suspension element, which engages under the functional frame by the frame segment. Due to the hook shape of the suspension element, a push-through of the suspension element is limited by the frame segment and at least a portion of the suspension element rests against a contact surface of the frame segment after being pushed through. Due to the flexible tongue of the suspension element, a preferably releasable attachment between frame segment and functional frame can then be effected in that the flexible tongue is bent behind the function frame and thus a positive connection between the hook element and functional frame on the one hand and frame segment and Anklemmelement on the other hand.

As a result, a system is provided which is easy to use in the do-it-yourself field and is highly flexible due to the bending of a flexible tongue of the suspension element that takes place during the application process and can be used at any thickness of the on-site frame segment or functional frame. Possibly. projecting lengths of the suspension element are bent over and parts thereof are cut off if necessary.

It is particularly preferred if a slide-in channel is provided on the on-site frame segment, in which the suspension element can be inserted. It is highly preferred if a complementarily shaped breakthrough is also provided in the functional frame. As a result, a particularly simple and secure connection is effected in the system according to the invention, without further preparation by the end user must be provided.

The bending of the flexible tongue of the suspension element is assisted by the choice of suitable materials, with steel plates being the preferred material of choice because of its strength and flexibility. For particularly large sheet thicknesses and / or particularly high strength of the material is also recommended, the introduction of at least one predetermined bending point in the flexible tongue of the suspension element to thereby allow bending by hand and without the need for tools.

It is particularly preferred if such a predetermined bending point are provided by one or more apertures such as holes in the flexible tongue. In particular, by a sequence of a plurality of mutually arranged in series round holes or perforations a suspension element is created, which is easily and continuously bendable along a plurality of defined predetermined bending points.

In an alternative embodiment of the invention, which is also particularly preferred, however, a slot is arranged in the flexible tongue of the suspension element, the longitudinal extent coincides with the longitudinal axis of the flexible tongue or at least arranged in parallel. As a result, a suspension element is created, which allows bending without the formation of individual predetermined bending points exactly at the desired location of the flexible tongue, preferably by hand. This is also achieved with particularly simple means.

The choice of material and dimensions for the flexible should be such that a bending of the flexible tongue by hand is possible and the suspension element then still has the advantageous for the purpose according to the invention inherent rigidity and shape retention.

In a further preferred embodiment of the invention, an additional covering cap is provided, which covers the flexible tongue resting on the function-warm flexible tongue after bending and fixes it in particular in this position. This not only the optics of the entire system is advantageously supported, but also the cap advantageously serves to fix that part of the suspension element with a defined distance from the on-site frame segment, in which later the functional frame can be hung. A displacement of the suspension element is thus blocked, whereby a readjustment of the suspension element by hand with particularly simple and secure means can be avoided even when hanging the functional frame.

Likewise preferred is an embodiment of the invention in which the functional frame consists of at least four side strips and four corner elements, wherein the corner elements and the side strips are designed with plug connections. Especially preferred is when the openings or insertion channels for the suspension elements are formed in the corner joints. As a result, not only a highly flexible design form for the functional framework is provided by Replacement of individual sidebars in height and / or length is easily changed, it is also a functional framework created in which the connection with the on-site frame segment on the suspension elements can be done exclusively on corner elements and without affecting the sidebars. In this case, an embodiment in which the openings for the suspension elements are provided in the corner elements is highly preferred.

Some embodiments of the invention will be described in more detail below with reference to the accompanying drawings.

1 shows a commercial insect screen frame, created from four hollow profile strips 20a to 20d , which by means of four corner connectors 21a to 21d to a rectangular functional frame 20 connected by the pressed-in (not shown) piping with a mesh fabric 30 is covered. For better handling are such functional frame 20 usually with two or more handles 31 . 32 provided in different ways on the functional frame 20 can be attached. Such insect protection frames have long been state of the art in a different embodiment.

2 shows the basic structure of such functional frame 20 , where profile strips 20a to 20d be cut to a desired length and by means of corner elements 21a to 21d put together and with a mesh fabric 30 via corresponding piping 40a . 40b are connected. Such functional framework 20 are functionally on the outside of the window frame or on-site frame segment 50 attached, as in the 3 us 4 are shown, and serve as insect repellent. For attachment to the window frame different fasteners are offered, which are designed primarily according to the design of the respective product and the shape of the respective profile. In essence, these fasteners are angular or hook-shaped and are primarily made of flat metal or spring steel wire. These mounting brackets or hooks are primarily connected by screwing or jamming at different positions with the insect screen frame or parts thereof, whereby the cover 20 is mounted on the window frame or other on-site frame segments.

According to the object cited above, for such functional frame frames, In particular, such Steckrahmensysteme created a system for attachment, which exemplifies in the 5 and 6 is shown. The system according to the invention uses an angle-shaped suspension element for this purpose 3 , which steplessly into a through hole (not shown) within the corner element 21 until the stop of the hanging element 5 ' on the window frame 50 can be inserted. As in the 5a) and b), can by slightly inserting the suspension element 5 the insect screen frame 20 be easily hung in the window fold. After this hanging the suspension element 5 as far as the arrow in the corner element 21 pushed in until the insect screen frame 20 firmly against the Fensterfalz, as in the 6a) and b) is shown. By bending the flexible tongue 5 ' more precisely that part of the flexible tongue 5 ' , as in 6b) shown by the corner element 21 has passed through, then takes a positive and possibly also positive connection between the functional frame 20 and the on-site frame segment 50 ,

The inventive system is designed so that between the functional frame and the suspension element a complementary, mechanical connection is created, which causes the angle-shaped suspension element when inserted in the direction of arrow and bending the flexible tongue 5 ' blocked in the opposite direction. By manually releasing this bend, the suspension element can be pulled out again and the functional frame can be removed from the window. For safe, proper attachment of a functional frame, such as an insect screen frame are of course in a preferred embodiment of the invention, all four corner elements 21a to 21d equipped according to the illustrated section. In this way, with an embodiment of the system according to the invention insect screen frames on window frames or other on-site frame segments with different design and fold thickness can be conveniently, advantageously and removably attached.

An inventive system thus preferably consists of an arrangement of in particular at least two parts, as they are exemplified in 7 are shown. For one, this is a corner element 21 , which with insertion channels 4a and 4b and a tongue bridge 5 On the other hand, this is a suspension element 3 , In this first embodiment, the insertion channels 4a . 4b essentially an angular breakthrough 4 (in the direction of the Y-axis of the coordinate symbol) through the corner element 21 therethrough. This breakthrough 4 is centrally positioned so that one leg of the angular shape to the Z-axis and the second leg to the X-axis indicates. In the diagonal symmetric center (ZX axis) of the breakthrough 4 , is a diagonal bridge 5 arranged, the breakthrough in two to this diagonal central axis mirror-identical insertion channels or insertion chambers 4a and 4b divides. According to the function of the system according to the invention, the suspension element 3 designed so that it form-fitting in both insertion channels 4a . 4b can be inserted.

In a first embodiment, the suspension element 3 formed substantially angular. A leg is preferably formed as a substantially rectangular plate, which serves as a stop or Anklemmlasche 3 ' serves. The second leg 3 '' is substantially rod-like, flat and in its cross-section preferably positive fit to the insertion channels 4a and 4b educated. Two outer surfaces delimiting the shape of the flexible tongue are bevelled at an angle of preferably 45 °.

As in the 8a) and 8b) shown is the suspension element 3 shaped so that it is in the insertion channels 4a and 4b can be inserted positively. Thus, an identical corner element 2 used for right or left or for top or bottom. As a result, in a kit insect screen frame four identical corner elements 2 and four identical suspension elements 3 may be included. Hereby, a fully functional system for attaching an insect screen frame as a functional frame, such as a bug frame on site frame segments created, with the function frame can be safely and removably attached to the desired location.

9 again shows a perspective view of one in a corner joint 21 through a slide-in channel 4 introduced hanging elements 5 , The insertion channel 4 has a substantially rectangular cross-section, which is complementary to the flat profile of the flexible tongue 5 ' of the hanging element 5 is trained. In the meaning of the invention, the suspension element 5 so far in the slot 4 Introduced that a defined distance between the front of the corner element 21 and the hanging strap 5 '' of the hanging element 5 is present. This defined distance preferably corresponds exactly to the width of the on-site frame segment into which the functional frame by means of the suspension element 5 to be hung. In this position then that part of the flexible tongue 5 ' that already passes through the through hole 4 has passed through, for example, bent by 90 ° up or down, so as to lie positively against the functional frame or at least parts thereof.

10 shows a rear perspective view of a system according to the invention, according to the front view 9 , As shown, that part becomes the flexible tongue 5 ' , which has already passed through the through hole, bent away by 90 ° downwards, so as to form-fit the flexible tongue 5 ' with the corner element 21 to obtain. In this position, the distance between the corner element 21 and the stopper element 5 '' of the hanging element 5 ' at least not bigger. In order to achieve a complete fixation of the suspension element in this position, moreover, a cap 6 provided so with the corner element 21 Connected is that the bent flexible tongue 5 ' their positive connection with the corner element 21 of the functional frame permanently. Thus, a shifting of the suspension element 5 both towards the cap 6 down and away from this safely prevented. Moreover, it is particularly preferred if in the corner element 21 as shown or complementary in the inside of the cap 6 a fold is provided in the flexible tongue 5 ' of the hanging element 5 can be inserted.
