The invention relates to a device for opening and / or Closing a wing according to the preamble of claim 1. Such a device also comes in doors and the like for use where opening and closing, for example for ventilation purposes, just closing, for example for usually open fire doors, or just opening is desired, e.g. for usually closed escape doors.

From US 2256613 is a device for opening a door discloses the door by means of a scissor-like linkage and a spindle drive opens. The spindle drive includes a spindle motor as a drive for a spindle and a Spindle nut.

Furthermore, the patent DE 42 19 316 C2 shows a device for Opening and / or closing a casement relative to a frame stick, which is a movable drive element for Generate a drive movement, as well as one for moving the Casement connected to the drive element in this way Output element includes that the drive element itself an idle stroke and moves relative to the output element moving a working stroke together with the output element performs. The patent particularly shows one electromotive fitting for a wing of windows or doors, which is also a spindle-spindle nut drive operated to issue the wing. In addition is an actuator with the spindle nut over one defined idle path coupled. For this is on Spindle nut attached to a spigot, which in one Angular slot of the actuator moves. Removed from Angular slot, the actuator is rotatable, however fixed to a frame stick. In the process of Spindle nut moves the pin along the idle path one side of the angle slot until it reaches the angle of the Angle slot reached. At this point the Raising motion. The patent states that the A sash can be used with a sash To finally lock or frame frame stick via locking pin Unlock.

In such a tilt and / or relative to a frame stick swiveling casement can be made on the whole or by a partially opened sash applied load that the wing beats, makes corresponding noises and is even destroyed. To hit like that must prevent in the known embodiment of the Pin, the angled slot, the actuator as well Sash frame and frame frame including their assembly points be narrowly tolerated accordingly. Hence, these must Parts of extremely high manufacturing quality with extremely low Manufacturing tolerances are sufficient. This makes one undesirable high effort.

The invention is based on the object, a reliable working, with less manufacturing effort producible device for opening and / or closing a Propose wing relative to a frame stick.

This task is accomplished by a device with the features solved by claim 1. Advantageous further developments are in specified in the subclaims.

Correspondingly, the connection between the drive element comprises and output element a lock that enables the Drive element at one end of its idle stroke releasably on the Determine output element. It is thus both about almost the entire range of movement of the wing Relative movement between output element and drive element reduced, as well as a flapping of the wing in part or fully opened position minimized. Still is with the wing essentially closed over the idle stroke motor locking possible.

According to a preferred embodiment of the invention the lock is angled, preferably at right angles to Movable direction of the drive element releasable bolt on. This angular arrangement enables a quick and in Movement range of the drive element can be precisely localized Locking of the input and output element. It also enables it training with a latch, the latch form-fitting and both in and against the Realize the direction of movement of the drive element.

To the number of powered and with energy too supplying components of the device according to the invention, and thus the installation, maintenance and repair work keeping it low is another one advantageous embodiment with a ramp or a Provided cam mechanism, or so in the Device is attached that a relative movement of Latch and ramp the latch between indented and moved out of position. So it can anyway movement of the drive element to be carried out are used, to release the locking of the input and output element. at this mechanism, the drive element in his Movement relative to a fixed ramp or a fixed cam mechanism so with the bolt in Intervention that come from an indented that Output element on the drive element, in a disengaged position allowing the idle stroke is moved.

To make a device that saves space in length realize, the bolt has a flange that with the ramp can be engaged. Preferably comes the Flange with the ramp by a relative movement of the latch and ramp engages and moves the latch between indented and disengaged position.

The slope of the ramp is preferably in a range from 10 ° to 50 °, preferably between 20 ° and 35 ° and am most preferably at 30 ° to speed up the or disengagement and the movement conditions of idle stroke too To influence the working stroke in such a way that rapid actuation the device is guaranteed.

Here lies the Spindle speed in a range from 15 to 60 1 / min, preferably in the range of 20 to 45 rpm and most preferably in the range 30 to 35 1 / min, and / or the slope the spindle between 1 and 2 and preferably at 1.5. This Conditions enable operation with reasonable Power consumption and an opening and / or closing of heavy wings.

The direction of movement of the Drive elements substantially parallel to one side of the closed wing and the drive element Scissor mechanism. In other words, it is Direction of movement of the drive element essentially parallel to one side of the frame stick when it is on the Frame stick is mounted, or essentially parallel to one side of the wing when it is mounted on the wing is. In this way, the drive element can optionally be equipped with a motor and associated energy supply invisible in the Frame stick can be accommodated.

The scissor mechanism preferably comprises a first one Scissor arm that is relative to the frame stick or the wing rotatable, stationary and on the wing or Frame stick is attachable and a second scissor arm, the is rotatably connected to the drive element. So it can the scissor mechanism described above an output lever comprise, which is rotatably connected to the drive element and transfers the working stroke to a scissor arm. The The scissor arm can then be relative to the frame stick or the wing rotatable but stationary, and on the other hand the wing or the frame stick.

The second scissor arm is advantageously relative to that Drive element in a direction substantially parallel to the direction of movement of the drive element displaceable appropriate. This displaceability enables linear Movable drives the idle stroke when the output element is not found on the drive element.

According to an advantageous embodiment, the first Scissor arm rotatably attached to the wing. The wing can thus only via the device according to the invention, or additionally via its own joint with the frame stick be connected.

The first scissor arm is preferably also in one Direction substantially parallel to one side of the wing stored. Such storage can be used if the sash itself is articulated to the frame stick is.

A driver can also be attached to the drive element be attached to lock the wing with the Frame stick serves. This enables one and the same drive during the empty stroke also for the Locking the sash on the frame stick is used for example by the driver in pins or the like on a pushrod of a window casement intervenes.

In Fig. 1 is a device 1 for opening and / or Closing a wing relative to a frame stick shown. In the embodiment is as Drive element shown a spindle nut 5 on one by a arranged in a housing 3 and not Spindle motor driven spindle 6 shown in more detail running. Furthermore, in the two end areas of the spindle Limit switches 7, 8 are provided for controlling the motor serve. The result is a translationally movable Mechanism that is sufficient with polygonal frame shapes long sides of the windows, doors, skylights to be moved or the like is advantageous. However, this form is pure exemplary, because they are also rotatable drives conceivable, and instead of the spindle drive shown can also belt, chain, linear drives and the like are used.

A scissor mechanism is shown as the output element. There is a first scissor arm 2 at one end 2R Frame stick (not shown; in Fig. 1 below) e.g. fixed rotatably via a motor housing 3 and on the other End 2F at least rotatable with the wing (also not shown; in Fig. 1 above) connected. A second Scissor arm, which is designed as an output lever 4, is on one end with the first scissor arm 2 between its ends rotatably and fixedly connected and at its other end a drive element 5 attached. There is one Y-scissors, which is, however, purely exemplary, since e.g. also X-scissors or other opening mechanisms such as angle levers are easily conceivable. Also, the device with the Motor housing 3 to be attached to the wing. In this case would be the end 2F of the scissor arm 2 on the frame stick attached. Scissor arm 2 and output lever 4 can also extend beyond the illustrated ends, e.g. around there by means of their continuation and movement to operate according to sash and / or frame stick.

Fig. 1 shows the device in a position in which the Wing is closed relative to the frame stick. In this Position is the output lever 4 on the drive element 5 rotatable and substantially relative to the drive element Slidably mounted parallel to the spindle axis. This enables a defined during the opening process Idle stroke 9. In addition, a is on the drive element 5 Driver 10 attached, for example with a Slide rod of the wing comes into engagement with this lock relative to the frame stick.

To the wing of the closed shown in Fig. 1 Position in the open position shown in Fig. 2 to bring, the spindle nut 5 moves along the spindle 6. The idle stroke 9 is first overcome without the wing opens. During this idle stroke the moves Driver 10 with the spindle nut 5 and unlocks the Connection between sash and frame stick. If the idle stroke is 9 overcome, the work stroke begins and with it the Opening process of the wing. At this point the Output lever 4 to the left in the drawing of the Drive elements 5 moves and a stop 11 engages (Fig. 2 and Fig. 4) to the output lever 4 relative to Determine spindle nut 5. With further movement of the Spindle nut 5 on the spindle 6 brings the wing via the output lever 4 and the scissor arm 2 in the open position. The wing can partially, however can also be opened completely.

The wing can float freely over the first Scissor arm 2 or, as shown in Fig. 3, additionally connected to the frame stick via its own joint 12 his. If the sash is articulated to the frame stick, depending on the dimensions and arrangement, this is the first scissor arm 2 typically at its end 2F both rotatable and in Slidable essentially parallel to one side of the wing connected to the wing. The first scissor arm 2 in a guide 13 which is integrated in the wing, longitudinally displaceable (Fig. 3).

To close the wing from, for example, an open one Position, which is shown in Fig. 2, the Direction of rotation of the spindle 6 reversed, so that the Spindle nut 5 along the spindle 6 in the direction to Opening the wing moves in the opposite direction.

During the entire opening or closing movement, the Output lever 4 on the spindle nut 5 through the bolt 11 detected. The bolt 11 is namely via a spring 16th biased so that it is when the spindle nut is outside the idle stroke 9, automatically a position takes in which he the output lever 4 relative to the Drive element 5 both in and against Specifies the direction of movement of the spindle nut 5. A Detailed view of the locked output lever 4 with the drive element 5 can be found in FIG. 4.

With the wing almost closed, however, the Spindle nut 5, as shown in FIG. 7, a ramp 14 or a cam mechanism. At this point comes one Flange 15 of the bolt 11 with the ramp 14 in engagement (Fig. 6). As soon as flange 15 and ramp 14 come into engagement by the relative movement between flange 15 and ramp 14 and by the slope of the ramp 14, the force of the spring 16 overcome, so that the latch 11 disengages. This is a relative movement between the output lever 4 and the Spindle nut 5 essentially parallel to the longitudinal axis the spindle 6 enables. Since the window on this Time already in an essentially closed position there is a further movement of the drive element 5 a stroke on the spindle without moving the wing, so an idle stroke 9. During this idle stroke the moves Driver 10, due to the closing movement of the wing engaged with, for example, a slide rod can be further. This can be used appropriately to lock the sash with the frame stick.
