Description

The invention relates to a corner deflection of espagnolette fittings for windows, doors or the like, consisting of a guide channel for a flexible deflecting member, for example spring steel strips, which is C-shaped in cross-section and has two legs arranged at right angles and an arc-shaped central piece.
and from a cuff rail that carries this on the back to cover a fitting groove that accommodates the guide channel and itself on a sash or frame corner, the guide channel abutting the bottom of its legs on the cuff rail and via this being firmly connected to the cuff rail.

Corner deflections of this type are already known in many different embodiments, as can only be seen, for example, from DE-AS 17 09 305 and DE-AS 20 46 856. In the case of DE-AS 17 09 305, the faceplate is designed as a faceplate rail, to the back of which the guide channel is fastened with each of its two legs to the legs that are perpendicular to one another. In the corner deflection according to DE-AS 20 46 856, however, only a straight faceplate piece is used, on the back of which the guide channel for the flexible deflection member is fixed with one of its legs so that the end of the faceplate section adjacent to the arcuate center piece is at least approximately at the plane of the Completes the outside of the free guide channel leg.

In the known corner deflections of the generic type, each leg of the guide channel which rests with its base on the back of a faceplate is connected to the faceplate by welding or riveting at least two places, namely on the one hand near the arcuate center piece and on the other hand near its free end to ensure a perfect longitudinal alignment of the faceplate and guide channel, as is essential for the proper operation of the espagnolette fittings.

A multiple riveting of each leg of the guide channel with the faceplate is not only cumbersome and time-consuming, because each riveting point must also be supplied with a rivet before the riveting process is carried out. Rather, after the riveting process has been carried out, the head of the rivet can protrude undesirably beyond the inner surface of the base on the guide channel, so that it undesirably inhibits or even blocks the longitudinal mobility of the flexible deflection member within the guide channel.

The welding of the guide channel to the faceplate requires that a galvanic surface coating, for example galvanizing, is not yet available or, e.g. is removed again by grinding, because this would significantly impair the durability of the welds.

In the case of surface treatment, for example galvanizing, of the components after the welding operations have been carried out, the disadvantage arises that the formation of an effective coating layer on the contact surfaces between the faceplate and the guide channel does not take place, so that there is a risk of undesired corrosion.

The invention has for its object to provide a corner deflection of the type specified, in which a proper mutual longitudinal alignment of the faceplate and guide channel can be achieved at least in the vicinity of the arcuate center piece of the guide channel while avoiding riveted and / or welded connections.

This object is achieved by the invention with the characterizing features of claim 1, namely in that a bracket or tongue section is formed directly from the bottom of the guide channel at least in the vicinity of its arcuate center piece, which with its longitudinal edges fits between the longitudinal edges of a cutout or engages a recess in the back of the faceplate.

It has proven to be particularly advantageous if, according to claim 2, the bracket or tongue sections are formed directly from the bottom of the guide channel into the cutout or the depression of the faceplate. For example, by pressing or embossing the stirrup or tongue sections in the region of split cuts made over most of the length of the cutout or depression in the bottom of the guide channel after the limbs of the guide channel have been brought into abutment against the back of the faceplate.

A particularly useful configuration can be achieved within the scope of the invention if, according to claim 3, the longitudinal edges of the cutout or the recess on the back of the bow or tongue sections are shaped inwards over their longitudinal edges, e.g. pressed or pressed, because this gives the possibility to use the material of the guide channel and the faceplate directly and exclusively without the need for welded connections.

To achieve a secure holding connection, it has proven itself in a further embodiment of the invention in this case if, according to claim 4, the depth of the bow or tongue sections is adapted to the thickness of the faceplate, i.e. the outside of these bow or tongue sections in the cutout of the faceplate with which The outside is approximately flush.

While the features of claims 3 and 4 together with the features of claims 1 and 2 advantageously in all existing connection points between the faceplate and the guide channel in Letting use be used, it turns out to be important when using the features that can be gathered from claims 1 and 2 only in the vicinity of the arcuate central part of the guide channel to use the inventive feature of claim 5, according to which namely the guide channel only on or near the free ends of its legs by riveting, for example via a connecting rod and / or fastening screw guide piece assigned to the back of the faceplate, is firmly connected to the faceplate.

Espagnolette and / or fastening screw guide pieces must be regularly assigned to the generic corner deflections and fastened ready for installation on the faceplate rails, so that they can also be used to help secure the guide channel to the faceplate rail.

In Fig. 1 of the drawing, a corner deflection 1 can be seen as it is used to connect drive rods displaceable at right angles to one another in drive rod fittings. It has a faceplate with a flat cross section in the form of a faceplate angle 2 with two legs 3 and 4 directed at right angles to one another.

On its rear side, the faceplate 2 carries a guide channel 5 for the longitudinally slidable reception of a deflection element 6, for example in the form of a plurality of spring steel strips lying one on top of the other.

The guide channel 5 has an essentially C-shaped cross section, which can be clearly seen in FIGS. 3, 5 and 6. It can consist of any sufficiently resistant, in particular metallic, material, but is preferably made of a brass alloy.

The guide channel 5 has an arcuate - in this case over an angle of 90 ° circular arc - extending center piece 7, to which two legs 8 and 9 - here in a mutually perpendicular position - are connected. The leg 8 of the guide channel 5 rests on the back over its entire length on the leg 3 of the faceplate 2, while the leg 9 of the same, also over its entire length, is in contact with the back of the leg 4 on the faceplate 2.

3 and 5 of the drawing it can be seen that the cross-sectionally C-shaped guide channel 5 has, via its flat bottom 10, contact with the back of the legs 3 and 4 of the faceplate angle 2, while its open gap 11 has these legs 3 and 4 the faceplate 2 is averted.

At the ends of the flexible deflection member 6, a pin 12 or 13 is attached, which protrudes through the longitudinal gap 11 from the guide channel 5 and is connected to a connecting rod connector 14 or 15.

Near the free end of each leg 3 or. 4 of the faceplate angle 2, a special guide piece 16 or 17 is provided which, according to FIG. 6, engages under the drive rod connection piece 14 or 15 with a support plate 18, while a web 19 of the same has a longitudinal slot 20 of the relevant drive rod connection piece 14 or 15 enforced. The web 19 of each guide piece 16 engages through the longitudinal gap 11 in the guide channel 5 and rests with a support surface 21 against the bottom 10 thereof. A rivet pin 22 projects from this support surface 21, which in turn penetrates a hole 23 in the bottom 10 of the guide channel 5 and also a corresponding hole 24 on the leg 3 or 3. 4 of the faceplate 2 passes through, so that it can be riveted to the outside. In the vicinity of the free ends of its two legs 8 and 9, the guide channel 5 is firmly connected to the faceplate 2 of the corner drive 1 in this way. Each guide piece 16 and 17 is also designed so that it can be penetrated by fastening screws, with the help of which the entire corner drive 1 can be attached to a corner of the window or door wing or frame.

In order to ensure a functionally reliable alignment between the faceplate angle 2 and the guide channel 5 of the corner deflection 1, also in the area of the corner angle apex and the curved center piece 7 of the guide channel 5, with the least possible technical effort, special precautions are taken. These precautions are that a bracket or tongue section 25 is formed directly from the bottom 10 of the guide channel 5, at least in the vicinity of the transition region between its arcuate center piece 7 and each of its legs 8 and 9, the longitudinal edges 26 of which fit between two parallel longitudinal edges 27 of a cutout 28 or a recess engages, the faceplate is worked out from the adjacent leg 33 or 4 of the faceplate 2 or is formed in the back thereof.

When the faceplate 2 and guide channel 5 are joined together, the stirrup or tongue sections 25 move or snap into the associated cutouts 28 or depressions and thereby easily and precisely bring about an exact fixing of the faceplate 55 relative to the faceplate 2 at the points distant from the guide pieces 16 and 17, namely in the vicinity of the arcuate middle piece 5, in a particularly clear manner 3 and 4 apparent manner.

Deviating from the snap-in connection, which can be seen in particular in FIGS. 3 and 4, a fixed connection can also be made in a simple manner with the aid of bracket or tongue sections 25 on the guide channel 5 and cutouts 28 in the faceplate or in the faceplate angle 2, as indicated in Fig. 5 of the drawing.

After the stirrup or tongue sections 25 on the bottom 10 of the guide channel 5 have been brought into engagement with the associated cutouts 28 of the faceplate or the faceplate angle 2, it is only necessary to do this, the longitudinal edges 27 of the relevant cutouts behind the back of the bracket - Or tongue sections 25, in the manner of flaps 29 to shape inwards over their longitudinal edges 26, for example by pressing or pressing using a suitable tool. As a result, the bow or tongue sections 25 are immovably fixed within the associated cutout 28.

In this case, it has proven to be advantageous if the depth of the shape of the bow or tongue sections 25 is adapted to the material thickness of the faceplate or the faceplate angle 2, so that the outside of these bow or tongue sections 25 in the cutout 28 with the outside of the faceplate or Forend angle 2 is approximately flush.

Finally, it should also be mentioned that the bracket or tongue sections 25 can only be formed out of the bottom 10 of the guide channel 5 after the guide channel 5 with its legs 8 and 9 has already been brought into contact with the back of the legs 3 and 4 of the faceplate angle 2 has been.

The tool used for this method of operation then only needs to have die stamps, while the associated male part is formed by the cutouts 28 located in the faceplate or faceplate 2.

It is obvious that the connections described above are not only useful for corner drives whose design corresponds to DE-AS 17 09 305. Rather, corner deflections of the type disclosed in DE-AS 20 46 856 can also be equipped with them, in which an angular guide channel 5 for the deflection member 6 is therefore only attached to a faceplate with one of its legs.
