Description

The invention relates to a window or a door with an arranged in a circumferential groove of the fold of the wing of the window or door espagnolette transmission according to the preamble of claim 1.

Such a window is already out of the DE 20 2004 010 424 U1 known. Here, a drive rod drive is provided on the window, in which a drive rod is indirectly driven by a gear mounted in a housing, which is in rotational drive with a shaft of an operating hand lever. The axis of rotation of the shaft is arranged in front of the fold and the gear engages over the drive rod on the fold side. The gear is associated with a Z-shaped slide, which is assigned to the gear with a first toothing and engages with a second, laterally offset teeth arranged on a stationary mounted in the housing intermediate gear. The intermediate gear serves the direction of rotation, so that the drive rod is moved according to a drive rod of a conventional fitting. Due to the fact that the toothed wheel engages over the drive rod on the rebate side, the direction of rotation is reversed, so that the operating lever in the closed position would stand upwards in the opposite direction to the usual position.

From the WO 2004/076788 A1 is known an espagnolette for a window, in which also a part of a drive rod is indirectly driven by a slide and an associated intermediate gear. However, the slider is directly connected to another portion of the drive rod, so that the drive rods are driven in opposite directions.

From the DE 203 08 230 U1 Finally, a drive rod transmission can be removed, in which the gear wheel driven by the operating lever interacts directly with the drive rod.

All the aforementioned embodiments have in common that they provide a Bedienungshebelweg of only 90 °. This is necessary because the travel of the drive rods require a pitch circle diameter of the gears, which is not available due to the limited space available, without further measures such as recesses are made on the wing.

Therefore, the above-mentioned embodiments are also not suitable for tilt and turn windows or doors in which a second tilt opening position is provided in addition to a first rotational opening position.

The invention is therefore based on the object deliver a window or a door ready in which the espagnolette a 180 ° lever movement permits, but also claimed only a small space, preferably in front of the circumferential groove.

To solve this problem, the invention provides that the intermediate wheel has at least two axially offset toothings, wherein the first toothing is associated with the slider and the second toothing of the drive rod and that the first toothing has a smaller pitch circle diameter than the second toothing.

Although it is from the DE 4324584 C1 already known to provide such an espagnolette transmission with a translation which is attached to an intermediate gear. In this case, however, it is provided that the intermediate gear is arranged at 90 ° relative to the axis of rotation of the shaft, so that the espagnolette gear can be arranged in total on the folding surface and in front of the drive rod. This causes at least a larger space in the rebate depth.

In contrast, the embodiment of the invention is able to be used even with narrow profiles of the window or the door. The required space perpendicular to the fold and in the rebate depth is relatively low, although a 180 ° rotational movement of the operating lever is achieved. The required Hubvergrößerung is achieved via the translation of the intermediate wheel, by the next also a reversal of motion and thus maintaining the switching sequence is effected.

It is further provided that the first toothing is mounted on both sides of the second toothing. This not only simplifies the assembly of the espagnolette because it can not lead to an incorrect arrangement of the idler, it also prevents a tilting of the slider in the housing, if this is also provided with two teeth, each one of the serrations of the idler be assigned.

In order to keep the space as small as possible, it is still expedient if the slide along the teeth assigned to the intermediate gear a recess has, through which the intermediate wheel engages with the larger pitch diameter, while the toothing of the slider of the second toothing is associated with the smaller pitch circle.

A particularly simple embodiment also provides that the first toothing of the intermediate gear is an involute toothing and the second toothing is a driving stick toothing. When the stick gear, the drive rod can be provided with recesses into which the teeth of the larger teeth of the intermediate wheel can engage.

It is also useful for the function of the espagnolette of the window or the door, when the slide is guided longitudinally displaceable in the housing and is supported on the rear side in the region of engagement of the gear or the intermediate gear. The Aushebekräfte the toothings are absorbed in this way without further action from the housing.

A particularly simple embodiment of the espagnolette mechanism provides that the housing is formed from two plate-shaped side walls, which are connected to one another in the region of the toothed wheel and the intermediate wheel via connecting webs. As a result, the side walls can be produced by punching sheet steel and have a high stability.

If the slide is supported on the connecting webs, then further measures on the housing for guiding the slide are not necessary. For the production, it is advantageous if the connecting webs are identical, since on the one hand a likelihood of confusion during assembly can be avoided and on the other hand, the number of connecting webs is increased.

To ensure the attachment of the operating lever to the espagnolette gearbox with the smallest dimensions, the side walls are connected via two threaded sleeves which serve as abutments for fastening screws of the operating hand lever and which lie on a common center axis with the axis of rotation of the shaft, the intermediate gear laterally offset from the threaded sleeves is arranged.

Further advantageous embodiments will become apparent from the description and the drawings. It shows:

• Fig. 1 a window in an overview,
• Fig. 2 a detail of a wing profile with a drive rod gear built therein,
• Fig. 3 an espagnolette in an enlarged three-dimensional representation,
• Fig. 4 a compilation of the slide, a first gear and an idler as a single representation without the housing,
• Fig. 5 an exploded view of another embodiment.

At the in Fig. 1 shown window 1, the wing 2 is connected to the frame 3 via hinge straps 4. On the wing 2, a control lever 5 is mounted, via which an espagnolette, not shown here, is driven.

From the espagnolette is in the Fig. 2 the espagnolette 6 visible. The drive rod gear 6 is mounted in a circumferential groove 7 on the fold 8 of the wing 2. The circumferential groove 7 is covered by a faceplate 9, which is part of the espagnolette gear 6. The axis of rotation 10 of the operating lever 5 is shown in the Fig. 2 before the fold 8.

From the FIGS. 3 and 4 It can be seen that the one lying on the axis of rotation 10 gear 11, the drive rod overlaps the fold side. The gear 11 has a polygonal receptacle 12, through which a drive connection with the operating lever 5 can be created. The gear 11 has a circumferential toothing 13, which is associated with a Z-shaped slide 14 and engages with a second toothing 16 at a fixedly mounted in the housing 17 intermediate wheel 18. From the housing 17 is in the Fig. 3 only a part shown.

The intermediate gear 18 has two axially offset toothings 19, 20, wherein the first toothing 19 is associated with the slider 14 and the second toothing 20 of the drive rod 21. The first toothing 19 has a smaller pitch diameter 22 than the second toothing 20. This results in a translation, since the larger pitch circle 23 describes a path that corresponds to the diameter ratio of the pitch circle 23 and the smaller pitch circle 22 relative to the travel of the slider 14 , With a travel of 24 mm on the slider 14, this results in a travel of 36 mm on the drive rod 21st

From the synopsis with the Fig. 5 also shows that the first toothing 19 is mounted on both sides of the second toothing 20. As a result, the intermediate gear 18 is given a transverse symmetrical shape and can not be mounted incorrectly in the housing 17. At the same time tilting of the slider 14 is prevented in the housing 17, since the load is symmetrical.

For improved guidance also contributes that the slider 14 along the intermediate gear 18 associated teeth 16 has a recess 24 through which engages the intermediate wheel with the larger pitch diameter, while the teeth 16 of the slider 14 of the teeth 19 associated with the smaller pitch circle 22 is. Together with the housing 17, whose width is matched to the width of the slider 14, this results in a better alignment of the slider relative to the intermediate 18th

The smaller toothing 19 of the intermediate gear 18 is formed as involute toothing, while the second larger toothing 20, which is associated with the drive rod, a driving stick toothing. The drive rod 21 can thereby be provided with recesses 24, in which engages the Treibstockverzahnung. This facilitates the production of the drive rod 21, which can be designed as a stamped and bent part. This also applies to the faceplate 9, which can be produced as a straight rod from a metal strip with a rectangular cross-section. The faceplate 9 has a recess 25 which is penetrated by the housing 17. The housing 17 consists of two plate-shaped side walls 26, 27, according to the embodiment Fig. 3 in the region of the gear 11 and the intermediate gear via connecting webs 28 are connected to each other. The longitudinally displaceable slide 14 is supported on the rear side in the region of the engagement of the toothed wheel 11 or the intermediate wheel 18 on the housing 17, so that the Aushebekräfte the toothings can be optimally absorbed and introduced into the housing 17. At the same time, the housing 17 is stabilized by the faceplate 9 in that the housing 17 is received and gripped in the recess 25.

It is expedient in this case that the connecting webs 28 are identical, so that on the one hand during assembly a confusion is impossible and on the other hand, the connecting webs 28 can be produced as stamped and bent parts in large quantities.

In addition, the side walls 26, 27 are still connected via two threaded sleeves 29, which serve as an abutment for fastening screws of the operating lever 5. The threaded sleeves 29 are located on a common central axis with the axis of rotation 10 of the shaft, wherein the intermediate 18 is arranged laterally offset from the threaded sleeves 29.

According to the embodiment Fig. 5 is unlike the one in Fig. 3 shown espagnolette 6, the housing 17 of two U-shaped angled side walls 26, 27 is formed. In the side walls beads 30 are introduced, which serve to guide the slider 14.
