The invention relates to a connecting rod fitting for windows and doors or the like, in which a housing for mounting a rotary member, e.g. a pinion, is seated on a faceplate, which is connected to a faceplate slidably guided drive rod is in engagement and in which the housing with opposing claws the faceplate cross-section encompasses positively in the area of edge notches to form a retaining connection.

Espagnolette fittings of this type are already part of the state of the art. They have the advantage that special operations such as riveting or welding are used to connect the gear housing to the faceplate. required are. Rather, when assembling the espagnolette fitting, it is only necessary to have the two housing halves with the edge notches to bring the faceplate into engagement and then inserted after the drive rod and the rotating member cooperating therewith are to rivet the two housing halves together. The entire transmission housing is then created simply by connecting the two halves of the housing fixed in its position on the faceplate by the claws engaging in the edge notches. This results from the saving at least one work step to facilitate assembly of the espagnolette fitting.

However, the previously known proposed solution also has various disadvantages. One of these disadvantages is that the faceplate is weakened by the edge notches and is therefore in the end area of the retaining claws the housing can easily bend. Such deflections can occur during the handling of the espagnolette fitting the attachment work occur. In many cases it is therefore necessary to straighten the bending faceplate during the stop work.

Another disadvantage of the known design can also be seen in that the retaining claws formed on the housing halves apply to the rear of the faceplate by the thickness of the material, so that when inserted of the espagnolette fitting in a profile groove on the window or door sash, either the profile groove in the area of the retaining claws is re-cut or a deflection of the faceplate must be accepted at the corresponding point. Finally it has also been shown that the gear housing can be moved lengthways relative to the faceplate by a small amount because the edge notches of the faceplate to simplify assembly, they have to be made slightly longer than the retaining claws of the housing parts.

The purpose of the invention is to overcome the disadvantages of such espagnolette fittings to avoid but retain their benefits. The main task of the invention is to provide a connecting rod fitting of the type described above To make the genus so that a dimensionally stable and play-free positive connection between the gear housing and the faceplate is created without the need for connecting elements on the rear opposite the faceplate.

The solution to the aforementioned first partial problem is provided according to the invention achieved in a simple manner by the characterizing feature of claim 1.

509812/0095 " ³ "

According to the invention, the features are used to solve the second sub-problem of claim 2 suitable and the third sub-problem can be solved in a simple manner by applying the features of claim 3.

In any case, this also means that the espagnolette fitting is perfectly supported in the profile groove receiving it is also achieved in the area of the transmission, the use of the features of claim 4 is also applicable recommend.

From a structural point of view, according to the invention, it has furthermore proven to be expedient proved to use the feature of claim 5, because this results in an exact alignment of the when assembling the espagnolette cooperating elements can be guaranteed particularly easily. So that after assembly the faceplate in every direction comes into engagement with the gear housing without play, the feature of claim 6 can also be used.

To stabilize the housing to be connected to the faceplate Furthermore, the characterizing feature of claim 7 is useful.

This means that as few as possible when assembling the espagnolette Individual elements have to be handled, the inventive feature of claim 8 can also be used advantageously and finally it has proven to be significant for creating a stable and yet graceful espagnolette bracket after installation, the characteristic Feature of claim 9 to use.

Practical tests have shown that a connecting rod fitting with the According to the invention, fastening of the gear housing to the faceplate not only meets the requirements for good stability and a perfect appearance

is fair, but also significant simplifications for you rational assembly of the espagnolette fittings.

In the drawing, the subject matter of the invention is shown in an exemplary embodiment. It shows

Fig. 1 in a spatial exploded view of the essential components of a espagnolette according to the invention,

Fig. 2 shows a cross section through the assembled espagnolette along the line Π - II in Fig. 1,

Fig. 3 is a view of the assembled espagnolette in Direction of arrow ΠΙ of FIG. 1.

The espagnolette shown in the drawing has a faceplate 1, behind which a drive rod 2 is guided longitudinally. With the faceplate 1, a gear housing 3 is connected in which a rotary member 4, for example in the form of a pinion, serving as a drive element is mounted is. This rotary member 4 is in positive engagement with a toothing 5, which is located in the drive rod 2 and within the transmission housing 3 is performed.

The gear housing 3 is composed of two housing halves 3 and 3, which can be designed as die-cast molded parts and, after assembly, in a plane parallel to the plane of rotation of the rotary member 4 butt against each other.

The faceplate 1 is in the fastening area of the gear housing 3

In the area of these edge notches 1 and 1, the gearbox housing 3 firmly connected to the faceplate 1 exclusively by form-fitting engagement. To make this possible, each of the two housing halves is

1 2

Each of these claws 6 and 6 has an inner claw leg 9, one outer claw legs 10 and a claw web 11 connecting them to one another.

12 12

The claws 6 and 6 are formed on the housing halves 3 and 3 so that that the inner claws9 at the same time the outer limitation of the

The thickness of the claw web 11 is on the other hand such that its

formed receiving grooves 13 and 13 so that they differ from> the opening side taper slightly wedge-shaped towards the groove base and have a width at the bottom of the groove that corresponds exactly to the thickness of the faceplate 1. As a result, when assembling the gear

1 2

Begehäuses 3 has a clamping effect between the claws 6 and 6 and the faceplate 1 are effected, so that the faceplate 1 can also be fixed without play transversely to its longitudinal direction.

To the two housing halves 3 and 3 together in a simple manner To be able to connect indissolubly is one of them, for example the

Housing half 3, equipped with molded rivet projections 16 and the other housing half 3 is provided with matching engagement holes 17. Rivet projections 16 and engagement holes 17 are slightly conical so that they are when the two housing halves are pressed together

1 2

3 and 3 come into engagement with a press fit and thus before implementation of the riveting process producing the end connection ensure secure cohesion.

1 2

Since the compression of the two housing halves 3 and 3 of the gear housing 3 and the riveting process for the permanent connection of the same can be carried out in one tool, it is obvious that the entire espagnolette can be assembled with the least amount of work. Because it's just necessary, first in one of the housing halves the faceplate 1, the drive rod 2 and the pinion 4 serving as a rotary member under coupling insert with the rack 5 and then press on and rivet the second housing half to create a stable functional connection between to get all parts of the espagnolette fitting.

The application of the invention is of course not restricted

only to the special embodiment shown in the drawing Gear housing 3. Rather, it can be used wherever the gear housing with a faceplate is used in connecting rod fittings must be connected.
