EP0542050A1 - Fitting for over 180 degrees towards inside or outside turnable window wings or similar - Google Patents

Abstract

The invention provides a fitting for wings, which can pivot or swing inwards or outwards through 180 DEG , of windows, in which the wing (2), at one end (4), can be pivoted and is displaceably guided in lateral rails (8) of the frame (1) and, when it moves, is carried and guided by lateral scissors arrangements (10) arranged in the rebate (20). The scissors arrangement (10), which is composed of a support arm (11), articulated centrally on the wing (2), and two bearing and guide arms (12, 13) bearing said support arm, are designed and arranged such that, in the closed position of the wing (2), all the arms (11, 12, 13) of each scissors arrangement (10), from their articulation points on the frame onwards, are located on that half of the wing (2) directed away from the displaceable pivot or swing axis (4a) of the wing. <IMAGE>

Description

The invention relates to a fitting for sashes of windows or the like which can be tilted or folded inwards or outwards by 180 °, with the features of the preamble of claim 1.

Such fittings are known in various embodiments. For example, British patent application 20 25 499 shows a fitting in which the support arm is articulated on the wing and is displaceably articulated on the frame and a control arm is provided which is articulated at both ends on the support arm and on the other to a mounting plate which can be screwed onto the frame . For the displaceable folding axis and for the displaceable articulation point of the support arm, a common guide rail with different guide sections for the different sliding pieces is provided in the fold on the frame.

In another embodiment (cf. DE-OS 21 25 639), the support arm articulated at one end on the sash frame is supported by two support and guide arms articulated on the support arm at a distance that are immovably spaced apart and which in turn are pivotably mounted on a screw-on plate are, which can be screwed onto the inside of the frame. The arrangement is such that in the closed position of the wing all arms of the laterally arranged scissors formed in this way are aligned from their frame-side articulation points in the direction of the folding axis at the upper end of the wing.

These and other known fittings of this type can be used in the case of sashes which can be folded outwards with the folding axis lying on the upper sash edge or in the case of sashes which can be tilted inwards with the tipping ash lying on the lower sash edge. All of these fittings have one or more serious disadvantages. In one case, a different fitting size is required even with relatively small changes in the height of the sash, so that a large number of fitting sizes must be kept ready over the entire possible height range. This compulsion moves forth from the simultaneous requirement to support each wing, regardless of its height, as close as possible to the middle of its height with the help of the support arm in order to obtain the best possible weight balance. On the one hand, wings that are not well balanced are more difficult to operate. On the other hand, when swiveled through 180 °, the lower wing end extends significantly beyond the upper frame end.

Another major disadvantage of one of the known types of fittings is that the two side scissors each have to be embedded in side cutouts in the frame. The incorporation of such millings is very difficult to achieve with frames made of plastic or light metal and is also complex with wooden frames. In addition, there is no covering of the scissors to the outside, which exposes them to the weather when the hinged windows open outwards. The large cutouts in the frame also affect the ability to seal the window sash. Such an arrangement is necessary because in this known fitting the wing passes all parts of the scissors, including the support arm, when it moves from the closed position into the 180 ° position, so that it can be pivoted over the large angle of 180 °.

It is an object of the invention to avoid the disadvantages shown and to further develop a fitting with the features of the preamble of claim 1 so that on the one hand the entire height range of the sash can be reliably covered with only a few fittings of different sizes, yet a good balance of the sash is ensured even with varying heights and, in addition, a better sealing possibility for the wing and at least partial protection for its scissor members can be achieved.

This object is achieved by the teaching of claim 1.

Due to this design it is achieved that a wing during its pivoting movement about the horizontal axis with its wing flap always remains at a distance from the articulation point of the support arm and does not pass it, but swivels around it, so that the support arm in the area of its articulation point and all over it Length in the closed position of the wing is reliably covered by the wing flap.

It is not necessary to mill out the sides to insert the scissors into the frame parts. Apart from the work required to screw on the guide rails and articulation plates, no further processing steps are required.

The fitting can be preassembled in terms of manufacture in that the two guide and supporting links of each pair of scissors are advantageously articulated on the guide rail. It only needs to be shortened to the height of the wing for assembly at a predetermined wing height, this shortening process can be carried out in equal measure from both ends of the guide rail, so that with wings of different heights always using the same fitting is that the wing is supported approximately in the middle by the support arm and thus balanced.

The fittings can be installed extremely easily and quickly. Due to the missing processing steps on the frame, the sealing in the closed position of the sash can also be carried out more reliably.

The new fitting can be used for both outward-opening sashes and inward-tilting sashes. In both cases, the links of the scissors extend in the closed position of the wing in the direction away from the movable folding or tilting axis of the wing.

The invention is explained in more detail below with the aid of schematic drawings using an exemplary embodiment.

each in the same representation cross sections through the frame in the wing closed position, namely along the section planes VV; VI-VI and VII-VII.

In the example shown it is assumed that the frames are full materials, e.g. is a wooden frame. The frame 1 can have a profiling on the side of the fold, as can be seen in FIG. 5. In the area of the vertical fold 20 (see FIG. 5), a profiled guide rail 8 is embedded in a fold groove of the frame. As shown in FIG. 4, this has a guide groove 8b which is open towards the fold and a fastening section 8a which is flush with the inner surface of the fold frame 1.

The wing 2 is designed as a folding wing in the example shown. It has a circumferential wing flap 3 of a predetermined width. With the folding wing, the horizontal folding axis lies in the area of the upper wing end 4. This folding axis is e.g. formed by lateral pivot pins which engage in the open groove 8b of the guide rails 8. The folding axis 4a can thus be moved over the height of the window opening in the guide rails 8, as is indicated by the double arrow.

To support and guide the wing during its movements, 20 scissors 10 are arranged in the side folds. Each pair of scissors 10 consists of a support arm 11, which is articulated in a non-displaceable manner at approximately the center of the wing at 6. At the other end of the support arm 11 and at a distance from it, two support and guide arms 12 and 13 are articulated, which in turn are articulated with their other end in the fold in the region of the fastening section 8a of the guide rails 8.

From FIGS. 1 to 3, as well as from FIG. 4, it can be seen that all of the links of the scissors 10 extend from their respective articulation points 6 and 15, 16 to the respectively assigned frame in the direction of the wing end 5, that of the folding axis 4a is turned away. This also applies in the closed position of the wing, from which the ventilation position according to FIG. 4 differs only slightly.

In the closed position of the wing, the support and guide arms 12 and 13 lie essentially one behind the other in the fold, a cutout 12a of the arm 12 in the closed position engaging over the nose-shaped end of the slightly angled other arm 13. The support arm 11, on the other hand, is in the closed position of the wing next to the two guide and support arms 12 and 13, namely, as is e.g. FIG. 6 shows, in the closed position, is completely covered by the wing flap 3.

If the wing 1 is opened from the closed position and pivoted over the positions according to FIGS. 1 and 2 into the 180 ° position according to FIG. 3, the wing overlap 3 always remains at a predetermined distance from the articulation point 6 of the support arm 11 and swings around this articulation point and around the support arm 11 without passing through it, so that the support arm 11 always remains behind the wing flap 3 in any position, seen from the outside of the wing.

If the fitting is to be used for sashes of smaller heights, only the rails 8 are shortened by approximately the same amount from both ends. Nothing changes in the relative position of the scissors relative to the window frame and the relative position of the articulation point 6 relative to the sash, so that all sashes can be supported approximately centrally and in a balanced manner with the fitting regardless of their height.

On the guide rails 8, in the area of the fastening section 8a, stops 18 projecting into the fold 20 are provided, which in the closed position of the wing up to the ventilation position shown in FIG. 4 have a finger-like projection 19 on the end of the support arm 11 supported by the support arms is attacked with game. The position of the finger 19 in the closed position is indicated by dashed lines in FIG. 4. The stops 18 are designed to be elastic so that they can be pushed back by an incline by the finger 19 and automatically snap back into place.

When used on a tilting wing, the tilting axis of the wing, which is displaceable in the rails 8, lies on the underside of the wing. In this In this case, all the links of the scissors extend upwards from their articulation points on the frame, in turn away from the tilting axis of the wing.
