EP3327236B1 - Device for opening and/or closing a wing - Google Patents

Description

The invention relates to a device for opening and / or closing a wing according to the preamble of claim 1.

It is known to use X or Y scissors to open a wing of a door or a window and to redirect the movement of a spindle drive in such a way that they correspond to the direction of movement of the wing. As a result, the spindle drives can be installed parallel to the frame structure of the wing and no longer protrude into the room. The power transmission between the drive and the scissors takes place with the help of push rods. A disadvantage of X and Y scissors are the low transferable forces when the scissors are close to the extended position. The straight position of the scissors is called the dead center position. When parallel-opening windows close, the scissors are located near this dead center position at the end of the sash movement. Further measures are necessary to ensure that the window is locked securely and that the window is pressed firmly against the seals. These are an additional locking motor with an associated locking mechanism or an additional construction, such as, for example EP 1389662 A2 known. In the EP 1389662 A2 the locking movement is achieved with the help of an appropriate idle stroke. The idle stroke of the scissors enables a locking stroke to be generated after the scissors have closed. Locking also takes place via a locking mechanism. The low forces of the scissors near the dead center also cause problems when opening the wing. On the one hand, the mass of the wing must be accelerated when opening, and on the other hand, pressing the wing away from the seals requires additional force at the start of the movement.

The DE 10148793 A1 is generic and discloses a parallel shut-off wing, and a device with all the technical features of the preamble of claim 1.

A spindle with a drive element and an output element is provided. After a partial stroke on the spindle, the drive element comes in

Contact with the output element, which acts on an articulated arm on a swivel arm. Auxiliary link and extension arm are connected to each other at a joint which is attached to the extension arm off-center. This ensures that the spindle does not begin to extend until a certain partial stroke has been completed.
In order to generate the deployment movement of the deployment arm, the joint is arranged eccentrically on the deployment arm, which prevents the arm from a dead center position. Nevertheless, there is a large torque on the extension arm, because in the initial phase of the extension movement the arms are almost on top of each other with their center lines and the torque around the wing axis of rotation is determined only by the distance of the joint from this center axis. It is therefore disadvantageous that the application of force to the extension arm at the beginning of the movement is very unfavorable. In addition, the arrangement of the joint on the extension arm is complex in terms of production technology and increases the overall depth.

From the DE 202012012548 U1 a swing door operator has become known, which provides a drive device mounted on the frame, which drives a pivotable extension arm. The extension arm engages with a pin in a wing-side guide. If the extension arm is swung out, the extension arm swings out the sash. In order to prevent overloading of the drive device during manual actuation, the drive shaft can be decoupled from the drive shaft by means of a coupling.

In the US 2,256,613 describes a door opening mechanism which can perform an automated opening movement on the door with an arm driven by an electric motor (32 there), but at the same time also permits the movement of the door independently of it. The electromotive actuation does not affect the otherwise possible manual opening of the door, it can remain open when the motor moves back, it can still be opened manually, even if the electric motor is not active and there is a "direct coupling" between the motor and The opening arm for opening the door is therefore avoided there. Nevertheless, the person skilled in the art takes from this document an actuator (there 32) which is pivotally mounted on a housing which can be mounted on the frame and in which an electric motor with a gear and the drive rod is arranged. However, the pivotable mounting necessarily includes an additional mechanical longitudinal movement of the pivot bearing, on columns described there with a guide (cf. there 25, 26 and 28/29). The drive rod described there is a threaded spindle and has no positive (fixed) coupling to the extension arm via the yoke there (there 27).

The patent also shows DE 42 19 316 C2 a device for opening and / or closing a sash frame relative to a frame stock, which comprises a movable drive element for generating a drive movement, and an output element connected to the drive element for moving the sash frame such that the drive element moves an idle stroke and moves relative to the drive element executes a working stroke together with the driven element. The patent shows in particular an electromotive fitting for a wing of windows or doors, which also uses a spindle nut drive to open the wing. In addition, an actuator is coupled to the spindle nut via a defined idle stroke. For this purpose, a pin is attached to the spindle nut, which moves in an angular slot of the actuator. Removed from the angled slot, the actuator is rotatably but fixedly attached to a frame frame. When the spindle nut is moved, the journal moves along the idle stroke along one side of the angle slot until it reaches the angle of the angle slot. At this point, the exhibition movement begins. The patent states that the free travel can serve to finally lock or unlock a casement with a frame stick via locking pins.
It is disadvantageous in the above-mentioned configurations that the devices require a comparatively strong motor due to their arrangements, since the arrangements described above reach a dead center position when opening and closing, which indeed allows space-saving reception, since all links are in the extended position, but do not have high closing or opening forces. In modern doors in particular, seals that are adjacent to one another must be pressed close to the plane-parallel position of the sash and frame.
There is therefore a need for a device which provides a simple design with a reliable push-off movement of the sash from the frame with the smallest possible dimensions and power of the motor.
The invention is therefore based on the object of avoiding the disadvantages mentioned and of achieving a safe and quick pivot opening of the wing with the smallest motor dimensions and power consumption. The invention is defined by claim 1.

To solve this, a link is provided, in which the drive element engages in the course of the partial stroke and reaches a support of the sash directed transversely to the direction of movement of the drive element against the frame. When opening, the invention thus provides support and shutdown of the sash in the first partial stroke, so that in a partial stroke following the first partial stroke, the driven element can be effectively controlled and, due to the partial opening that has already taken place, favorable force relationships prevail.

The backdrop is rotatably arranged on a pivotable arm, which is effective between the sash and frame and swings out when passing through a backdrop follower arranged on the drive element. The swinging arm takes up a small amount of space and larger opening movements can be achieved with small dimensions.
A simple, stable and easily producible embodiment provides that the arm is designed as a plate which is pivotably attached to the frame or sash and has a link for engaging a link follower which is movable together with the drive element, the plate pivoting out when the link follower passes through the link ,
If the plate has a pin projecting in the direction of the wing or frame, which engages behind a strip on the wing or frame when the wing is approaching in a plane-parallel position, then when closing the wing via the device, it can move into a plane-parallel position when the wing is approaching sealing pressure setting to the frame can be overcome more easily.
An alternative solution provides that the drive element engages with a link follower in a link of a stationary plate, so that although the parking movement is less, arms that protrude in the open state are avoided.

A particularly simple embodiment provides that the link has an inclined course and mouth openings in the direction of movement of the drive element, so that the link follower can pass through the link completely and leave it again in a simple manner.

In the Fig. 1 the frame 1 and the wing 2 of a door is shown. Frame 1 and wing 2 are interconnected via hinges, not shown here. In addition, a device 3 is effective between them. The device 3 causes the wing 2 to pivot or close via a motor 5.

For this purpose, the device 3 is fastened along a folded surface of the frame 1 and consists of an elongated housing 4 which supports the motor 5 at the end remote from the axis of rotation and which is drive-connected to a spindle 6 via a coupling (not shown). The spindle 6 is assigned a drive element 7 with a spindle nut 8. The drive element 7 is guided to be longitudinally displaceable in the housing 4, so that the drive element 7 can be moved along the same by rotating the spindle 6. In the housing 4, an output element 9 is also guided. This is connected to a swivel-mounted extension arm 10, to which a fixed pivot bearing 11 is assigned on the wing side.

Furthermore, an arm 12 is provided on the housing 4. The arm 12 is pivotally mounted on the housing 4.

The drive element 7 and the driven element 9 are spaced apart from one another in the surface-parallel alignment position of the wing 2 relative to the frame 1, as in FIG Fig. 2 seen. The pivot bearing 13 of the arm 12 is arranged near the first end position of the output element 9. The arm 12 is provided with a link 15 on its flat surface 14 facing the housing 4. A link follower 16, which is attached to the drive element 7, engages in this ( Fig. 3 ). The backdrop 15 has a wave shape with only a slightly curved wave slope towards a more narrowly curved wave head.

The arrangement of the link to the link follower 16 and the pivot bearing 13 is such that the arm 12 pivots out as it passes through the link follower 16 and passes through it completely. From the Fig. 4 it can be seen that the drive element 7 carries a coupling device 17 which can be connected to a coupling member 18 on the driven element 9 and enables a detachable connection of the drive element 7 and the driven element 9. In the illustrated embodiment, the coupling device 17 consists of two gripping jaws 19. These lie in a recess 20 of the drive element 7 which is open at the edge, while the coupling member 18 is a cylindrical pin 21 which is attached to a projecting tongue 22.

The recess 20 is arranged such that the pin 21 can enter it when the drive element 7 is approached to the drive element 9. A bar 23 can be assigned to the arm 12 on the wing 2, which the arm 12 can engage behind in a closing process with a pin 25 projecting in the direction of the wing rebate 24.

The operation of the arrangement described above is as follows:
If, starting from a closed position of the wing 2, the drive element 7 is displaced by energizing the motor 5 and the resulting rotation of the spindle 6 in the direction of the output element, after a first partial stroke of the drive element, the latter follows the link follower 16 into the link 15 of the arm 12 and this swings out in a further partial stroke and is supported on the wing 2, which is thereby turned off by the frame 1 ( Fig. 5 ). In the further course, the link follower 16 emerges from the link 15 and the pin 21 enters the recess 20 and the drive element 7 is coupled to the output element 9 ( Fig. 6 ). In a further partial stroke, the wing 2 then opens via the driven element 9 and the extension arm 10 until the wing 2 is completely open.

When the wing 2 is closed via the device 3, the motor 5 is operated in the opposite direction of rotation and the wing 2 approaches its surface-parallel position with the arm 12 pivoted out. If the wing 2 in or near the in Figure 5 is shown position, the arm 12 engages with the pin 25 next to the bar 23 and the link follower 16 pivots the arm 12 so that the pin 25 can reach behind the bar 23 and pulls the wing 2 to the frame 1 with further pivoting movement.

Through a link 15, in which the drive element 7 engages in the course of the partial stroke and a support of the wing 2 against the frame 1 directed transverse to the direction of movement of the drive element 7 is achieved. In the first embodiment, the link 15 is arranged in the arm 12 which is pivotably mounted on the housing 4 and which is active between the sash 2 and the frame 1 and which swings out when the link follower 16 arranged on the drive element 7 passes through. The embodiment provides that the arm 12 is designed as a plate which is pivotably attached to the frame and which has the link 15 for engaging the link follower 16 which is movable together with the drive element 7. The backdrop 15 is arranged so that the plate swings out when the backdrop follower 16 passes through the backdrop 15.

Another embodiment not according to the invention is in the following Figures 7 to 16 shown. The figures show a schematic representation of the frame-side housing 4 with the drive element 7 guided therein. The output element 9 is pivotally connected to the extension arm 10. The extension arm 10 is pivotally and slidably mounted in a guide 30 at the other end. The sliding guide is effected by a slider 31, to which a control arm 32 is also pivotally attached. The control arm 32 is received at its other end 33 in a frame-side pivot bearing.

On the wing 2 is fixed in a rail 34 in addition to the guide 30 and a plate 35 which is at a distance from the drive element 7 in its end position, which corresponds to the closed position of the wing 2. The output element 9, which is likewise guided in the housing 4, lies behind the plate 35 in the direction of displacement of the drive element.

The drive element 7 and the output element 9 have a coupling device 17 in the form of two strong magnets 37, 38. On the underside, the drive member 7 has a projecting link follower 16.

In order to pivot the wing 2 by means of the device 3 about the vertical axis of rotation 39, the drive element 7 can start from the Fig. 7 and 12 can be moved in the direction of the output element 9. This is done as previously described with a spindle - not shown here - and a spindle nut on the drive element. If the drive element 7 via the spindle in the Fig. 12 Moved to the left, the backdrop follower 16 enters the mouth 36 and the wing 2 is further supported on the backdrop 15 via the backdrop follower 16 and is exhibited ( Fig 8 and 13 ), the wing 2 pivoting about the axis of rotation 39.

Finally, the drive element 7 meets the output element 9 and is coupled to it via a coupling device 17. The extension arm 10 now acts on the wing 2 at a less acute angle 40 due to the previous extension movement ( Figure 13 ). The Figures 14 and 15 show that as the opening width increases, the angle 40 now becomes larger and therefore cheaper.

From the Fig. 16 it can also be seen that the control arm 32 has an angle 41. With this, the control arm 32 engages around the axis of rotation 39, so that an opening angle greater than 90 ° is possible.
