Description

The invention relates to an espagnolette fitting for windows, doors od. Like., With a faceplate and with one behind this by means of it attached guide pieces longitudinally slidable drive rod.

Such a drive rod fitting is from DE-GM 83 23 365 already known. The espagnolette fitting points to the Back of a faceplate at predetermined locations Guide piece that, for example, under a rivet pin with a Face plate is firmly connected. The guide pieces known here are made from a molded part, in this case from die-cast zinc, and have a T-shaped cross section, the web against each other supports the back of the faceplate and the two flanges together form a foot part, which is against the bottom of the groove support.

Because of their shape resulting from the manufacturing process results, the guide pieces serve the purpose of longitudinally movable bracket of the connecting rod, in which it with its web pass through a longitudinal slot of the same and the flanges Support support rod. On the other hand, the flanges form also an additional support of the whole Espagnolette fitting, in which the flanges are on the groove base support. In addition, two are at a distance Opposed troughs formed limited passages that lead to Guide the fastening screws for the connecting rod fitting serve. The fitting is characterized by a basic position to keep until the end of the stop work on the hardware components.

To achieve this goal, a safety link made of shearable Material, for example plastic or die-cast zinc provided, which after a functional test of the existing Fitting component in the recess provided in the guide piece for example automatically with the help of a mounting device is pushed in. The diametrically away from each other Longitudinal ribs of the securing member penetrate above the Foot part of the guide piece in the notches Drive rod and hold it against longitudinal displacement in one predetermined basic position.

This makes it possible that until the end of the striking work, especially until the connecting rod sections of the corner fitting parts the drive rod of the edge gear is properly coupled, a predetermined one, for the correct functioning of all fitting parts necessary basic position of the movable elements relative to the load-bearing or leading cuff rails are preserved.

The known solution proves to be disadvantageous in that the Guide piece manufacturing technically very complex and therefore a higher cost is associated.

Under certain circumstances, the guide piece, which in the Face plate is riveted due to, for example, transportation to the various assembly facilities through the game which is located between the drive rod and the guide piece, insofar twist that it is not, or only very badly in the Hardware fitting groove of the window profile can be installed.

Another guide piece is known from DE 196 46 988. That Guide piece described here as a holding element has a Base body, the two outer surfaces of which each have projections stick outwards. These projections are resilient, with their free ends at different distances from the Bottom of the base body are prepared. Reason of this Case different projections is that the holding element in two different fitting grooves can be used. To the one has a fold profile a fold groove, which by a The groove projection is narrowed. The holding element lies with its underside at the bottom of the groove and is in this system by the two resilient Protrusions held behind the groove projection. On the other hand is the holding element in a rebate groove of a second rebate profile used in which the groove walls have no protrusion, but are smooth. They are in both fold profiles resilient projections designed so that they are wider in any case are dimensioned as the groove walls of the intended folded profile and thus achieve a clamping or friction effect. The attachment of the Holding element on the faceplate is made by two locking projections which snap into a corresponding opening in the faceplate. There is also a between the holding element and the faceplate Push rod arranged on the contact surfaces of the holding element is present. A corresponding longitudinal recess in the push rod or Push rod enables the push rod to be moved opposite the holding element. In the final assembly position, this will be The faceplate is fixed to the profile with the help of a screw an opening in the faceplate and the mounting hole reaches through.

To the push rod relative to the holding element until after the final To fix the installation of the window, a centering pin engages in one appropriate recess in the push rod and holds this initially immovable to the holding element. After installing the window can e.g. by pressing the window handle for the first time Centering pin at a predetermined breaking point defined by Holding element can be canceled.

This holding element or guide piece is a Plastic injection molded part, which is very complex to manufacture, because it has a resilient effect and a dimensionally stable effect got to. If you assume that the hardware is installed normally, a functional test of the same is not possible because the Centering pins which are intended for the basic position, ahead of time would break off the predetermined breaking point.
