task It is the object of the present invention to provide a device for pivoting rotatably mounted wing elements to create, which is protected against manipulation attempts and climatic influences.

These The object is achieved by a pivoting device according to the independent claim. The dependent claims relate to advantageous embodiments the invention.

In a device according to the invention for Pivoting rotatably mounted wing elements, the by means of bands attached to a fixed component becomes a driving force or transmit a torque for pivoting the wing member to a pivot member. The pivoting element causes a rotational movement of the wing element and can be rotatably connected to a band.

When wing element For the purposes of this application are all types of window, door or Gate wing too understand that pivoted about a horizontal or vertical axis of rotation can be. The wing elements can to close a wall opening or a passage, or to protect behind-windows or doors be provided. Here you can leaf or multi-leaved (e.g. double-leaf) Forms are used. A wing element is with one or several bands for example, attached to a wall or a post.

Preferably is a drive unit for generating the driving force for pivoting in the wing element arranged. The drive unit may be completely or partially in the wing element are located. By the arrangement of the drive unit in the wing element is this from the weather, like rain, snow or intense sunshine, as well as manipulation attempts protected by unauthorized persons. This is how you face it the prior art increased burglary security and achieved a lower wear.

Conveniently, is an axis of a rotating shaft of the drive unit, for example the Rotor of an electric motor, arranged inside the wing element. The Axis of the rotating shaft can be parallel to a longitudinal axis or rotation axis of the pivoting element may be arranged. In this way creates a cheap Arrangement of the drive unit, in which the axis of rotation of the drive unit parallel and / or offset in the radial direction to the axis of rotation of the wing element is arranged, wherein the drive unit protected by the wing element may be provided in the interior.

Preferably, the pivoting element is designed as a sleeve connected to the drive unit and a bearing pin provided on the belt. When sleeve and bearing pin are non-rotatably connected to each other and the sleeve is rotated by the drive unit with respect to the wing member in rotation, resulting in a torque which leads to a pivoting of the wing member. Of course, the pivoting element can also be designed as a pin offset from the drive unit in rotation, which engages in a rotationally fixed manner in a sleeve attached to the belt.

to non-rotatable connection of pin and sleeve are many form-locking designs possible. Especially useful it, the inner shape of the sleeve and the outer shape the pin polygonal to design.

The Sleeve and The bearing journal of the pivoting element can also be a bearing element for the wing element form, which is a pivoting of the wing element allowed. By inserting the driven pin into a Sleeve becomes a simple mounting of a pivotable about a vertical axis wing element achieved. The sleeve Fulfills in this case also the function of a bearing element for the pivotable wing element, by the weight of the wing element (or part of it) wearing.

The Pivoting device according to the invention can be realized in one or more of the bearing elements for a wing element. Basically However, it is sufficient, a bearing element by an inventive pivoting element to replace the wing element to pivot means of the driving force. For larger doors or gates, however, it can be advantageous, several bearing elements (hinges) as pivoting elements to make the necessary torque on several, one each Distribute swivel element associated drive units. This has the advantage that smaller drive units with lower power and size used can be the easier in the wing element can be accommodated.

Conveniently, is the longitudinal axis the pivoting element parallel to the median plane of the wing element (or their main directions) and staggered with respect to these. This arrangement has the advantage that a fully opened wing element parallel to a, in relation to the longitudinal axis can rest against the wall of the pivoting element protruding wall. The parallel shift the axis of the pivoting element to a major axis of the median plane of the wing element allowed, in the open Condition, a parallel arrangement of wing element and outside the masonry and allows a complete opening of the wing element.

Especially It is advantageous if the axis of rotation of the bearing element or the longitudinal axis of the pivoting element outside the space is arranged in the extension of the wing element lies. In this case, the axis of rotation of the wing element is located offset to this and allows a complete opening, at the pivoting device, for example, by 180 ° open wing element to a given Offset to the longitudinal axis positioned the pivoting element and so a complete opening of the wing element at a protruding wall opening allows. The position of the pivot axis relative to the intersection of the planes of contact of housing angle and shutter can be set so that when closed the outside visible level of the shutter is flush with the outside of the masonry. in the open State, both planes are parallel and aligned.

Preferably the drive unit has an electric motor. This can as be formed a DC collector motor. However, too other electric motors, such as alternating current or three-phase motors, for Use come. Conveniently, allows the electric motor makes a rotation in both directions, so that opening and Shut down the wing elements by reversing the direction of movement of the umpolbaren electric motor is easily achieved without requiring a reverse gear is.

The Driving force can over transmit a gear unit from the engine to the pivot member and this into a rotation with respect to the wing element offset. By the gear unit, a reduction of the Speed of the drive unit and so a larger torque or a smaller drive unit (lower power required, smaller dimensions) achieved become. The reduction gear can in the form of all known types of transmissions be educated. Particularly advantageous is a planetary gear, which has a small size. The reduction gear can also be used as a unit with the Engine be formed (geared motor).

By However, a suitable embodiment of the transmission unit can also the offset between the longitudinal axis the pivot member and the axis of the rotating shaft of the drive unit be compensated. For this purpose, in particular a spur gear appropriate, that is driven by the drive unit and via two or more stages (gears) one Driving force on the pivot member transmits. The gear unit can also have a bevel gear, in which case the axis the rotating shaft of the drive unit is not parallel to the longitudinal axis the pivoting element is arranged. This allows, for example, a right-angled Arrangement of the drive unit to the pivot axis, which is advantageous may be to accommodate the drive unit in the wing element.

The gear unit can also be a self Have inhibitory transmission, which allows a power flow only from the drive unit to the pivot member and not in the opposite direction of force. In this way, a self-locking or self-locking pivoting device can be realized in which the wing elements can not be moved by hand. This has the advantage of an increased burglary protection, since it is not possible for unauthorized persons to pivot and open a closed wing element when the drive unit is switched off. A self-locking gear requires no additional locking of the wing element. As a self-locking gear worm gear or circular thrust transmission can be provided.
