Abstract

The invention relates to a drive arrangement for a pivoting wing with a connecting mechanism which comprises a drive module with a drive housing, which is articulated on the pivoting wing on the one hand and on an associated frame, by means of the drive movement of which the pivoting wing can move between its closed position and its open position, wherein the drive housing surrounds one is mounted at a distance from its center of gravity extending pivot axis. In this case, the drive housing can be in the closed position of the swing-wing about the pivot axis, with extensive elimination of the game in the pivoting direction, move in a constructively defined end position.

Description

The The invention relates to a drive arrangement for a swing wing according to the preamble of claim 1.

Such a drive arrangement for a movable relative to its fixed frame swing wing, the z. B. as a tilting window, as a French window, as a ventilation flap or the like. Can be formed, is from the DE 201 20 604 U1 known. The integrated in the connection mechanism drive module for the swing wing comprises an elongated, cuboid drive housing, in which a by a geared motor extend and retracting drive chain is arranged. The drive housing is pivotally mounted on arranged at the ends of the housing bearing brackets on the frame profile of the pivoting wing, while the free end of the drive chain is articulated on the fixed frame. The predetermined by the bearing brackets pivot axis runs along a rear side of the drive housing, whereby the center of gravity of the drive housing has a significant distance from the pivot axis. The weight of the drive housing thus generates a moment about the pivot axis, which must be supported via the drive chain. Depending on the structural conditions, the drive housing can take a slightly tilted with respect to the horizontal plane end position with closed swing wing due to height clearance on the chain side. However, this can be undesirable because the impression of a less solid drive solution can be conveyed by tilting the drive housing out of the horizontal plane and the associated game. In addition, it can possibly lead to increased wear of the drive mechanism by the tilting movement of the drive housing as a result of the game.

Of the Invention is based on the object, a drive assembly for a swing wing according to the preamble of the claim 1 to develop the appearance of a solid construction can impart the drive assembly.

The The object is solved by the features of claim 1.

The Subclaims form advantageous design options the invention.

The Drive assembly according to the invention could in the simplest case, z. B. by manual loading of the drive module with elimination of the existing game in the constructive final position are moved, in which the drive module is held thereafter.

Around to allow a more comfortable operation of the drive assembly However, the drive module can preferably by means of an auxiliary drive automatically into the game eliminating Move end position. A particularly simple embodiment for such an auxiliary drive is by a spring arrangement created by the spring force of the drive module constantly loaded in the direction of the stop means fixed end position is. Optionally, as a stop means also z. B. using adjustable screws adjustable stops used to compensate for tolerances an exact adjustment to make the intended end position of the drive module.

at an elongated drive module, which in itself known manner at its ends pivotable about bearing brackets is stored, preferably in each of the two bearing brackets be integrated into one of two synchronously acting load springs. Particularly space-saving can be in the bearing brackets to this Arrange structurally adjusted leg springs. So can this under compact arrangement a support sleeve in the joint area enclose the assigned storage console. Here is It is easily possible, with adaptation to the dead weight different heavy drive modules with varying drive solutions to use different strength springs, by their spring force the end position of the drive module reliably taken becomes.

In order to no additional slinging to limit the Relativverschwenkung of the drive module to the pivot axis defined by the bearing brackets are required, these can be advantageous from controlling Circumferential contours of a screw-on plate and one moved with the drive module Be formed support plate of the bearing consoles. As a controlling circumferential contour can provide the mounting plate with a wedge-shaped stop lug be in a fork-acting, wedge-shaped Recess of the support plate with correspondingly larger Wedge angle engages. It is understood that stop lug and fork stop this must be in a common plane of rotation.

Preferably is the final position of the stop lug in the fork stop, over which the spring force is supported, so on the constructive fixed end position of the drive module tuned in that Endposition at least one peripheral side of the drive module in one at least approximately horizontal plane lies.

in the Below is an embodiment in the drawing explained in more detail with reference to FIGS.

2 the perspective view of the drive assembly with partially opened pivoting wing;

3 a side perspective view of a console portion of the drive assembly;

4 the storage console according to 3 in a separate exploded view;

In the 1 and 2 is a drive arrangement 10 shown with a swing wing 20 a window between its closed position and a not shown, completely open position can swing. The rectangular frame of the swing-wing 20 grips in the usual way a translucent glass and is along the lower wing profile with a hinge 21 around a horizontal axis on the lower frame profile of the window frame 22 pivoted. The upper frame profile of the swing leaf 20 is in the central central area by a drive chain 11 hinged to the opposite profile of the window frame 22 connected.

For the articulation of the chain end serves a chain holder 12 standing on the frame profile of the window frame 22 is fixed. Due to the articulation of an eyelet end of the last chain link on a horizontal axis of the chain holder 12 is the drive chain 11 pivotally mounted in the vertical direction. The drive chain 11 is composed in a known manner from an authoritative for their length variety of chain links, which are interconnected via pivot joints formed by bolts. At the drive chain 11 the bolts near one of their narrow sides are arranged vertically at a constant distance parallel to each other, while adjacent chain links on the opposite narrow side with just stretched drive chain 11 supported on each other. That means the drive chain 11 from its straight stretch position only to the bolt side can bend articulated. Therefore engages from the bolt having the narrow side of a matching sprocket 13 in the drive chain 11 one.

The sprocket 13 in turn is in a drive housing 14 rotatably mounted, in which the drive chain 11 through a central opening on the window frame 22 the opposite side of the housing is inserted. The elongated, rectangular in cross-section and a total of approximately cuboid drive housing 14 is in turn at the two ends via a respective storage console 15 on the front of the upper profile of the swing leaf 20 attached. Because the drive housing 14 is shown with removed housing cover, can be the laying of the inserted drive chain 11 within the drive housing 14 clearly recognize. The drive arrangement 10 can also be arranged in the reverse manner, with the in the bearing brackets 15 pivotally mounted drive housing 14 on the window frame 22 and a suitably adapted chain holder 12 on the swing wing 20 is arranged.

After passing the right angle between the window frame 22 and the drive housing 14 spanned drive chain 11 in the drive housing 14 At first, it wraps around the chain sprocket engaging in it 13 and is bent over a guide means by about 90 degrees. After this turn, the drive chain extends 11 first straight on the right end of the drive housing 14 to, before it is deflected by 180 degrees and thus in the opposite direction back to the with the sprocket 13 provided center region of the drive housing 14 to extend. This space-saving installation of the drive chain 11 is secured by a U-shaped curved guide in conjunction with a corresponding guide channel, the drive housing 14 itself and the removed housing cover is limited. By a rotary drive of the chain pinion 13 clockwise through one in the left half of the housing of the drive housing 14 invisible arranged electric geared motor 16 can the drive chain 11 thus lengthwise to an end position of the drive housing 14 be extended, causing the swing-wing 20 maximum is moved to its fully open position.

Will the chain sprocket 13 by switching the geared motor 16 rotated counterclockwise, so the drive chain 11 lengthwise back into the drive housing 14 retracted and takes the U-shaped curved storage position shown in the drive housing 14 again, with the swing-wing 20 about the in 2 shown intermediate position again to his in 1 shown closed position on the window frame 22 is used. In this closed position is the swing wing 20 over the geared motor 16 stopped because the mechanical gear of the geared motor, z. B. is formed by an integrated worm drive, self-locking. To additional locking means are for the swing wing 20 thus not required.

When opening and closing the swing-wing 20 over the drive chain 11 becomes the upper frame profile of the swing leaf 20 on a circular path around the geometric axis of the hinge band 21 emotional. The occurring height offset relative to the chain holder 12 must at the two mirror-symmetrical bearing consoles 15 via a rotation between the drive housing 14 and the swing-wing 20 be balanced so that a tilt-free engagement of the sprocket 13 in between the chain holder 12 and the drive housing 14 straight running drive chain 11 can be done. The adaptation of the current rotational position between the drive housing 14 and swing-wing 20 finds automatically about the lowering of the drive chain 11 with increasing distance from the chain holder 12 instead, taking the swing wing 20 facing peripheral side of the drive housing 14 over the axis of rotation of the chain pinion 13 perpendicular to the straight chain direction between window frames 22 and drive housing 14 is aligned.

In 3 is the geometric pivot axis 17 drawn around which the drive housing 14 by means of the bearing consoles 15 relative to the axially parallel frame profile of the swing leaf 20 is pivotally mounted over the required angular range. This pivot axis 17 runs close to the flat rear of the drive housing 14 and thus at a considerable distance from the centerline of the drive housing corresponding approximately to the central longitudinal axis 14 , Due to the weight of the drive housing 14 Thus, a moment is generated by the bearing brackets 15 clockwise about the pivot axis 17 are charged. This moment is supported by a spring drive, so that the drive housing 14 is held in its constructively fixed end position, in which the upper and the parallel lower peripheral side of the drive housing 14 horizontally and at right angles to the plane of the swing leaf 20 are aligned.

As in connection with the separate views of one of the two mirror-symmetrical bearing brackets 15 in the 4 . 5 and 6 can be clearly seen, which is the geometric pivot axis of the hinge 21 parallel axis of rotation 17 from the bore center of a bearing ring 15.1 determined, the transverse to the plane of a rectangular mounting plate 15.2 protrudes from the bottom. The mounting plate 15.2 is at two laterally adjacent oblong holes 18 under surface contact with usual, not shown fixing screws on the front side of the upper frame profile of the swing wing 20 screwed. About the screw fastening of the mounting plate 15.2 is the protruding from this bearing ring 15.1 securely fastened, as the bearing ring 15.1 and the mounting plate 15.2 one piece z. B. die cast aluminum, are made. Furthermore, on the visible end of the screw-on 15.2 a wedge-shaped stop nose 15.3 formed, which under cover to the bearing ring 15.1 but at a lateral distance to it, from the bottom of the mounting plate 15.2 projects.

In the vertical plane of the stop plate 15.3 is a support plate 15.4 the warehouse console 15 around the center longitudinal axis of the bearing ring 15.1 aligned rotary axis 17 pivoted. The plane of rotation of the support plate 15.4 runs at right angles to the plane of the opposite mounting plate 15.2 , and parallel to the front of the drive housing covered by it in the lower corner area 14 , In the overlap area between the support plate 15.4 and drive housing 14 these are fixed but easily detachable, with a multi-membered connection between the two through a hole in the support plate 15.4 through with a fixing screw 19 is secured.

In the mounting plate 15.2 facing end region is from the broad side of the support plate 15.4 a hollow cylindrical support sleeve 15.5 transversely, whose bore is provided with an invisible internal thread. In this internal thread is in the assembled state, a pivot pin 25 with a threaded shaft 25.1 screwed in, the threaded shaft 25.1 from the end of a cylindrical bolt shank 25.2 protrudes with a larger diameter. The stud shaft provided with a screw head at the other end 25.2 penetrates a washer 26 and then the bore of a bearing bush 27 , in turn, the bore of the bearing ring 15.1 be upheld. In this case, the bearing bush 27 on the support sleeve 15.5 facing end on a molded collar. When the axle bolt is screwed in 25 is the bearing bush 27 thus in the bearing ring 15.1 against the annular end face of the support sleeve 15.5 held, reducing their storage position within the bearing ring 15.1 is secured. The carrying sleeve 15.5 is with some circumferential play of the winding of a thigh spring 28 enclosed, the axially between the annular end face of the bearing ring 15.1 the broad side of the support plate 15.4 is arranged. In this case, a spring leg of the torsionally prestressed leg spring 28 on the support plate 15.4 and the other spring leg on the mounting plate 15.2 supported. The on the support plate 15.4 acting rotary drive force of the leg spring 28 is doing over the shorter leg of a wedge-shaped widening fork stop 15.6 supported. This fork stop 15.6 is made of two straight boundary surfaces of a triangular recess of the support plate 15.4 formed from the the grommet 15.2 facing corner area is recessed. Will the support plate 15.4 against the spring force of the leg spring 28 from the drive housing 14 pressed down, so is first the existing rotation of the stop lug 15.3 between the legs of the fork stop 15.6 balanced before the other leg of the fork stopper 15.6 on its opposite surface of the stop nose 15.3 abuts, bringing the support plate 15.4 is blocked against further panning. Thus, the required rotational play is ensured even in unfavorable tolerance position, was the square leg base of the fork stopper 15.6 through a roughly semicircular groove 15.7 widened.

With closed swing wing 20 is the drive housing 14 thus, due to the in the consoles 15 arranged torsion springs 28 formed auxiliary drive automatically moved to the specified end position. Because the torque of the torsion springs 28 in the by fork stop 15.6 and associated stop lug 15.3 fixed end position remains effective, the drive housing 14 held in its always the same, stable end position after its displacement.
