Description

The invention relates to a fitting according to the preamble of claim 1.

A fitting of this type is described and shown in DE-A-29 04 986. As a so-called supplementary protection, this fitting is assigned a spring holder, which is formed by a fork encompassing an articulated bolt of the raising arm, which is arranged in the free space of an offset of the guide rail forming the articulation. The fork is held in a form-fitting manner, on the one hand by being immersed in a slot in a drive rail present below the guide rail and, on the other hand, by positive engagement in a recess in the guide rail.

This mounting of the fork requires a complicated form of the same, a longitudinal slot having to be machined into the drive rod, which enables the fork to be immersed. In addition, the known fork mount is not only subject to a relatively large amount of play, but there is also the risk that the fork arms will break off due to the loads to be expected during operation.

The invention has for its object to find a configuration for a fitting of the present type, which enables a simple design and attachment of the spring bracket with high resilience.

This object is achieved according to the teaching of claim 1. In the case of a fitting designed according to the invention, the extent of the free space formed by the offset is used to fix the elastic component. It is therefore not necessary to immerse or intervene in other components, because the definition in the window plane is ensured by the limitation of the free space itself and transversely to the window plane by the pivot pin dipping into the elongated hole. Due to the presence of an elongated hole that is completely closed, the hinge bolts result in elastic walls that are enclosed between them, which are not clamped on one side, as in the prior art, but are clamped on both sides and are therefore also more resilient. Due to the narrowing of the elongated hole between the end areas, both an additional security and an opening security against wind load are guaranteed. In the prior art, simultaneous securing against opening is questionable simply because, because of the then relatively long fork arms, there would no longer be sufficient clamping force or the fork arms would have to be made particularly stable.

In an embodiment according to claim 2 - at least seen transversely to the window plane - there is a planar contact of the circumference of the elastic part on the circumferential surface of the free space. A suitably designed elastic component has simple and easy to produce outer contours, whereby - as already with an embodiment according to claim 1 - a rotation of the elastic component about the longitudinal axis of the hinge pin is prevented in a special way because the circumference of the elastic component lies fully.

During operation, the walls of the elastic component, which enclose the hinge pin between them, are required to have a considerable clamping force, so that adequate locking against opening or opening is ensured even in the case of large windows. The embodiment according to claim 3 achieves the advantage that without widening the elastic component, i.e. without thickening the elastic walls, the strength thereof is increased, so that there is greater security against opening or slamming. This higher strength is achieved in that the elongated hole is designed as a blind hole, the bottom of the elongated hole being divided lengthways, so that the walls are sufficiently elastic.

The embodiment according to claim 4 also leads to the advantage that the extension arm can not be lifted for the purpose of unauthorized entry when the wing is tilted to z. B. unhook the wing. When the extension arm is lifted, it is necessary to remove the elastic component beforehand in order to be able to execute the hinge pin through the slot widening. However, the elastic component can only be removed after unscrewing the screws with which the guide rail is fastened. However, loosening these screws is hardly possible when the wing is tilted.

In a further embodiment of the invention, the definition of the elastic component according to claim 5 can be increased by the fact that the elastic part is positively enclosed in the widening of the slot with an attachment and is therefore additionally fixed. However, this does not require an additional recess, but an existing recess, namely the expansion of the slot, is used.

The envisaged positive engagement in the expansion of the slot can of course replace the all-round encirclement of the elastic component in the free space of the offset while maintaining the advantages according to the invention. For this reason, such an embodiment is also protected in subsidiary claim 6.

The design according to claim 7 enables several tilt positions of the wing, the wing can be tilted by hand into the desired locking position. In the case of an embodiment according to claim 8, the elastic component is additionally fixed against being displaced transversely to the window plane by being accommodated in the faceplate groove.

In order not to impair the freedom of movement of the elastic walls encompassing the hinge pin, it is advisable, in accordance with claim 9, to assign external indentations in the area of narrowing or narrowing the elongated hole. In the free space created by these retractions the walls surrounding the hinge pin move in when the hinge pin is pulled through the elongated hole when the wing is tilted.

The molded body proposed in claim 10 is intended to ensure that the hinge pin cannot be unintentionally or unauthorizedly lifted out of the expansion of the slot. The molded body is combined with the spring holder according to one of claims 1 to 4, wherein the spring holder is produced as a separate part or in one piece with the molded body or also in one piece with the guide rail.

Claims 11 to 18 contain expedient configurations of the shaped body. The molded body can be designed as a molded or pressed part, in particular made of plastic.

Exemplary embodiments of the invention are described in more detail below with the aid of simplified drawings.

For reasons of simplification, the fitting to be described is only partially shown, specifically in the area of a turn-slide connection, generally designated 1, in which the wing-side end of an extension arm 2 is connected to the wing, not shown.

The extension arm 1 includes an elongated hole 4 with a hinge pin 3, which is formed in the region of a cranked section 5 of a faceplate 6. The hinge pin 3 engages behind the cranked section of the faceplate 6 with a bolt head 7, which can be inserted through an end extension 8 of the elongated hole 4 for the assembly or disassembly of the rotary-slide connection 1. On the side of the faceplate 6 facing away from the deployment arm 2, a drive rod 9 extends, to which latches, not shown, for fastening the wing are fastened.

In the position shown in FIGS. 1 and 2, the wing is in its closed position. In the tilted position of the wing, the hinge pin 3 moves in the elongated hole 4 - based on FIG. 2 - to the right into the position shown in broken lines. This end position in the tilted position of the wing is designated by B, while the other end position of the hinge pin 3, in which it is in the closed position of the wing, is designated by A. The cranked section of the faceplate 6 thus forms a guide rail 11 for the hinge pin 3.

In the free space 12 formed by the cranking of the faceplate 6, a plastic fitting piece 13 is arranged, which is adapted to the shape of the free space 12 and is thus held in a positive manner in the free space 12. The fitting piece 13 has an elongated hole for the engagement of the bolt head 7.

The elongated hole 10 is designed as a blind hole and is dimensioned so long (1) that the bolt head 7 can execute the required stroke h in the elongated hole 10. Between the end positions A, B of the hinge pin 3, the elongated hole 10 is narrowed on both sides, so that the hinge pin 3 during a longitudinal displacement must push apart the walls 14, 15 overlapping it with a force that is greater than a force that is exerted on the wing under normal wind pressure works. The narrowing of the elongated hole 4 is denoted by 17.

The evasion of the walls 14, 15 is facilitated by a longitudinal separation of the bottom 16 in the form of a slot 18. The halves 19, 20 of the blind hole base 16 thus take part in the dodging of the walls 14, 15, whereby the strength of the walls 14, 15 is increased.

In the area of the narrowing 17, the fitting piece 13 is narrowed on both sides by cutouts 21, so that the width b of the fitting piece is not exceeded when the walls 14, 15 deflect. This configuration is particularly advantageous when the fitting 13 is seated in a known rebate groove which receives the faceplate 6.

Due to the all-round encirclement of the fitting 13 in the offset and the engagement of the hinge pin 3 in the elongated hole 10, the fitting 13 is fixed on all sides in the free space 12.

An additional definition is achieved in that an extension 22 projects from the side of the fitting 13 facing the deployment arm 2, which approximately encloses the extension 8 of the elongated hole 4. Because of this additional definition, it is possible to arrange the fitting piece 13 without having to encompass its end faces 23, 24. The fitting 13 could, for. B. be dimensioned approximately as long as the guide rail 11.

Since the length of the elongated hole 10 is dimensioned smaller than the length 2 of the elongated hole 4, the elongated hole 10 thus ends before the extension 8, the fitting piece 13 also fulfills the purpose of securing the lifting arm 2 from being lifted out namely a previous transverse positioning and longitudinal displacement of the fitting 13, which is prevented on the one hand by the all-round wrap and on the other hand by the positive reception of the extension 22 in the extension 8.

Such a displacement of the fitting 13 is only possible after loosening the faceplate screws arranged at 25. A loosening of these screws 25 from the outside is hardly possible when a bracket is tilted.

Within the scope of the invention it is of course also possible to fasten a cranked additional part on the faceplate instead of the one-piece cranking of the faceplate, e.g. B. welded.

In Fig. 6, the upper leg of a wing is designated 30. A stepped groove 31 is formed in this leg, which has an inner groove step 32 for receiving a drive rod 33 and an outer groove 24 for receiving the faceplate 35. The faceplate 35 is designed with an offset 36, which serves as a guide rail for the wing-side end of an extension arm 37. A slot 38 is provided on the guide rail 36, which extends in the longitudinal direction of the faceplate 35 and has a circular extension 38a. A pivot pin 39 is attached to the extension arm 37, whose shaft 39a corresponds to the width of the slot 38 and whose head 39b is somewhat smaller in diameter than the circular extension 38a, so that the head 39b can only be passed through the extension 38a but through the slot 38. The drive rod 33 is combined with the faceplate 35 in a manner known per se to form a structural unit, so that the drive rod 33 is guided on the faceplate 35, for example, by mushroom heads (not shown). The faceplate 35 is fastened to the wing leg 30 by fastening screws 40, which pass through the longitudinal holes 41 in the drive rod 33 and penetrate into the bottom of the inner groove step 32.

A molded body 42 is received below the guide rail 36 and has an extension 43 which engages in the circular extension 38a and is flush with the top of the guide rail 36. The shaped body 42 is otherwise trapezoidal in the view in FIG. 6, so that it also engages under the bevel of the bent portion 36 and is thus secured against rotation. In addition, the molded body 42 is also immersed in the outer groove step 34, so that security against rotation is also ensured here. The bolt head 39b strikes against the molded body 42 in its left end position according to FIG. 6 and therefore cannot step into the area of the circular extension 38a and cannot be unintentionally or unauthorizedly lifted out of it. The left end position of the opening arm 37 shown in FIG. 6 corresponds to the closing position of the window sash in relation to a window frame; this position is essentially maintained even if the sash is rotated about a vertical axis in the case of a tilt-and-turn window. On the other hand, when the wing is tilt-opened about a horizontal tilt axis, the hinge pin 39 moves in the slot 38 to the right until it abuts the right-hand slot end and thereby defines the tilt opening width.

After the fastening screws 40 have been loosened from the wing 30, the drive rod 33 can be spread apart with respect to the faceplate 35 and thus with respect to the guide rail 36, that after the spreading has taken place, the extension 43 of the molded body 42 can be pulled out of the circular extension 38a and then the molded body 42 out of the Gap between the guide rail 36 and the drive rod 33 can be removed. Installation takes place accordingly. As can be seen from FIG. 7, the molded body rests on the step base 34a of the outer groove step 34, possibly also on the drive rod 33.

8 shows the trapezoidal shaped body 42 in plan view with the extension 43.

FIG. 9 shows a modified molded body 142 with an extension 143, the molded body 142 having a square plan, corresponding to the line 142a shown in broken lines in FIG. 6. The circulation ratios otherwise correspond to FIG. 7.

10, the shaped body 242 is designed with a circular base. It does no harm if it can turn in the circular extension 38a, since the stroke conditions are not changed. The contact conditions in the embodiment according to FIG. 10 correspond again to FIG. 7.

11 shows that the molded body 342 can also rest on the intact surface 330a of the wing leg 330 adjacent to the stepped groove 334.

Finally, FIG. 12 shows an embodiment in which a simple groove 431 is embedded in the casement 430 only for receiving the drive rod 433. Here, the molded body 442 lies on the undamaged surface 430a on both sides of the groove 430.

The application of the invention is also possible if the drive rod 433 according to FIG. 12 is not accommodated in a groove 431 but, for example, rests on the intact surface 430a and is guided thereon by mushroom pins (not shown). In this case, the faceplate could be omitted entirely and only the guide rail 436 could be present, which would then have to be notched in a U-shape at its ends in order to overlap the drive rod 433. The molded body 442 could then either rest exclusively on the drive rod 433 or in its base surface facing the undamaged surface 430a an open channel for the passage of the drive rod 433 so that the molded body 442 can be supported on the undamaged surface 430a and, if necessary, additionally on the drive rod 433.
