EP2107199B1 - Fitting for an at least tiltable and/or parallel parkable wing of a window, door or similar - Google Patents

Description

The invention relates to a fitting for a means of Ausstellarmen against a fixed frame at least tiltable and / or parallelable and movable in this position wings of a window, a door or the like, with at least one drive and a releasable locking device for or at least one of his Ausstellarme located Parallelabstelllage, the one or the Ausstellarme, in particular the lower closing side Ausstellarm, by means of a control arm in its Parallelabstelllage can be locked by a locking member of the control arm engages in a locking receptacle.

A fitting of this kind is for example from the DE 32 34 677 A1 known. Similar fittings are from the EP 1 251 444 A1 , of the DE 30 50 971 A1 , of the DE 89 00 806 U1 and the EP 992 648 A2 known. These fittings all have the disadvantage that they either have a complicated structure or are not to be regarded as barrier-free by the lower threshold.

The invention has for its object to provide a fitting that has a simple structure and is also suitable for wheelchairs or barrier-free in terms of applicable guidelines.

To solve this problem, a fitting is proposed which has the features of claim 1.

This fitting is simple, since the lower threshold does not have to be designed for receiving and guiding a carriage. It also allows for easy crossing of the lower threshold by means of a wheelchair. It must only be present a rail in which a sliding insert is slidably mounted, wherein the sliding insert the lower Ausstellarme are articulated. However, this rail can be sunk in the ground.

The track, in which the upper drives are guided, is located on the upper spar of the fixed frame, where it does not interfere.

Further advantages, features and details of the invention will become apparent from the subclaims and the following description in which a particularly preferred embodiment is described with reference to the drawing.

In a fixed frame 10 is a wing 12, which can be permanently installed or can be opened in a known manner, for example, rotatable and tiltable and / or displaceable. One further wing 14 is tiltable and parallelablocked and he can be moved in the parallel parking position in the sense of the double arrow 16, where he, seen from the interior of the room, can be brought when moving before or behind the wing 12.

The wing 14 is connected to the fixed frame 10 via Ausstellarme, preferably four Ausstellarme are provided, namely two lower Ausstellarme 18 and 20 and two upper Ausstellarme 22 and 24. The latter are each mounted on a drive 26 and 28, in particular the FIG. 3 clearly shows. The drives 26 and 28 are coupled together via a coupling rod 30 or the like. They each have two rollers 32 and 34 and are guided on a running rail 36. This is posted on the inwardly facing side of the upper horizontal spar 38 of the fixed frame 10. Therefore, the running rail 36 does not prove to be disturbing or obstacle, especially for wheelchair users. The drive-side pivot bearing of the opening arms 22 and 24 are denoted by 40 and 42 and the wing side with 44 and 46. On the coupling rod 30 is also a lift-off 47 ( FIG. 3a ), for example by means of a screw which has a radially projecting securing member 49 which engages behind a Randleise the running rail 36. In this way, a lifting of the wing 14 is prevented.

On at least one of the extension arms, in the embodiment on the upper right extension arm 24, a catch tab 48 is slidably guided. The guide groove of the catch tab 48 is designated 50. The catch tab 48 prevents twisting of the opened wing 14th

In FIG. 4 the extension arm 18 is shown in an enlarged view. This is, as well as the Ausstellarm 20, via a pivot bearing 54 attached to a sliding insert 52, wherein the pivot bearing, with which it is fixed to the wing 14, 56 is designated. The two sliding inserts 52 are firmly coupled together via a coupling rod 58 or the like, wherein the two sliding inserts 52 are guided in a flat slide rail 60 slidably. This slide rail 60 is struck on the inward facing side of the lower horizontal spar 38 of the fixed frame 10. It can be clearly seen that the sliding inserts 52 have a very small height, which is why the slide rail 60 has small vertical dimensions. In this way, the seated on the lower spar 38 threshold 62 may have a very low height, so that they include wheelchair suitable, ie is easily traversable.

On at least one of the opening arms, in the embodiment on the lower left Ausstellarm 18, a control arm 64 is rotatably articulated. The pivot bearing is designated 66. The control arm 64 is provided with a control groove 68, which is also clear in the FIGS. 5 and 6 is shown. In the control groove 68 engages a guide pin 70 which controls the movement of the control arm 64 during the closing operation of the wing 14.

The free end 72 of the control arm 64 is, as from the FIGS. 5 and 6 recognizable, provided with a locking member serving as a hook 74 which engages behind a serving as a locking receptacle for the locking member nose 76 of a control member 78. The control part 78 is displaceable in the longitudinal direction in or on the slide rail 60 and mounted on this fixable.

The control arm 64 moves with the sliding insert 52 together with the wing 14 in the direction of the double arrow 16 and is held by the guide pin 70 which engages in an angularly bent, terminal portion 84 of the cam 68. As the hook 74 approaches the control member 78 upon closing of the wing 14, the free end 72 abuts a control surface 80 which directs the hook 74 of the control arm 64 into the recess 82 behind the tab 76. In this case, the guide pin 70 is lifted out of the section 84 of the control groove 68 and can now move freely in the control groove 68. The extension arm 18 and the control arm 64 now form a scissors bearing with the pivot bearings 54 and 66 and the rear grip of the hook 74 behind the nose 76 as the bearing points. The free end 72 of the control arm 64 is no longer fixed on the sliding insert 52 but on the control part 78. If the wing 14 is further displaced in the closing direction, the sliding insert 52 moves with the pivot bearing 54 away from the control part 78, so that this scissors bearing spreads. In this case, the guide pin 70 runs in the guide groove 68 of the control arm 64 and pulls the pivot bearing 66 and the pivot bearing 66 superior portion of Ausstellarms 18, to which the wing 14 is attached via the pivot bearing 54 in the direction of the frame 10. The wing 14 takes then his tilted position.

In the FIG. 4 is still a retaining spring 84 can be seen, which is attached to the sliding insert 52 and presses against the control arm 64. As a result, the guide pin 70 is held securely in the section 84 of the control groove 68, so that the Ausstelllage of the wing 14 is stable.

The FIG. 3 shows the two upper Ausstellarme 22 and 24, where the wing 14 is mounted in pivot bearings 44 and 46. In the extension arms 22 and 24 engage the upper ends of height adjustments, which in FIG. 7 are shown in detail and in enlarged reproduction.

In the FIG. 7 the height adjustment is shown with raised, located in neutral position and lowered wing 14. The in the extension arms 22 and 24 cross-upper end of the height adjustment is designated 86 and is part of a Tragarmbolzens 88. This Tragarmbolzen 88 is rotatably supported by two needle bearings 90 and 92 in a corner bearing 94. The needle bearings 90 and 92 are seated in the corner bearing 94, whereas the Tragarmbolzen 88 can be moved axially in the needle bearings 90 and 92.

To adjust the altitude, an adjusting screw 98 is screwed into the upper end 86 opposite lower end 96, the head is supported by a thrust bearing 100 at the front end of the corner bearing 94. If the set screw 98 is rotated, then the support arm bolt 88 raises or lowers in the corner bearing 94.

To secure the screw 98 against self-twisting this is provided with a coaxial threaded bore 102 into which a threaded pin 104 is screwed, which presses with its free end 106 on the bottom of the blind hole 108 of the Tragarmbolzens 88 and thereby the set screw 98 against the corner bearing 94th braced.

In addition, it can be seen that the Tragarmbolzen 88 between the two needle bearings 90 and 92 has a constriction 110 into which engages a held by the corner bearing 94 locking pin 112 in approximately tangential direction. The Tragarmbolzen 88 can be moved only between the two ends of the constriction 110 in the corner bearing 94. By the locking pin 112 prevents the wing 14 with the corner bearing 94 from Tragarmbolzen 88 drops. The raised position of the height adjustment for the wing 14 is in the Figure 7a , the Neutral position in the FIG. 7b and the lowered position in the FIG. 7c shown.
