Description

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

A drive arrangement for a rotary wing is from the DE 103 01 016 A1 known. The rotary wing is opened by means of an electric drive motor and closed by means of a spring accumulator drive with helical compression spring, wherein the helical compression spring is tensioned during the opening movement of the drive motor and the spring accumulator drive is thereby charged. Thus, the drive operates in the so-called normal operation, in which the rotary wing after its release can still be reliably moved by the expanding compression spring in its closed position even in case of power failure. This function is particularly important for so-called fire doors of fundamental importance, which should be reliably closed in case of fire to prevent the spread of fire. The compression spring and the drive motor are in this known construction via a gear transmission constantly in operative connection, so that more extensive interactions can be achieved. For example, the drive motor during the expansion of the compression spring, be rotated by the belt drive to act as an attenuator. In transmissions without self-locking of the electric motor can even be operated as a generator to even the sudden abruptly initiated by the spring force closing operation of the revolving door or mitigate by decelerating.

Furthermore, from the DE 199 49 744 A1 a generic drive arrangement known in which the rotary wing closed by means of a drive motor and can be opened after release of the rotary wing by means of a spring-loaded drive. This arrangement is intended for so-called escape doors swinging to the case of play in an emergency despite power failure after release of the rotary wing by the force of the spring drive in their open position and thus immediately release the escape route.

None the two drive arrangements described is suitable for each Another application, so far a wide variety of drive arrangements had to be kept.

1 a front view of a closed revolving door with a drive arrangement for the rotary wing;

2 a schematic horizontal section through a housing of the drive assembly.

An in 1 visible drive arrangement 1 should have a hinge hinges 3 on the associated door frame 4 Swiveling vane about a vertical axis 2 between its open and its closed position. This is above the door opening on the door frame 4 a housing 5 fastened, from the underside in the hinge-side end region a coupling region, for. B. square of a drive shaft 6 protrudes. The coupling area of the drive shaft 6 passes through a parallelepiped sliding arm 7 and is rotatably via a driver connection with the sliding arm 7 connected, causing it in a below the housing 5 and above the rotary wing 2 lying horizontal plane is guided swinging. At the free end of the sliding arm 7 a slider is arranged from the top into a slide rail 8th with a U-shaped cross section engages. The straight slide rail 8th is in turn under length coverage to the housing 5 near the top door edge on the broadside of the rotary wing 2 attached. After loosening the rotary wing 2 on the provided with a door handle lock side can be the rotary wing 2 thus by turning the drive shaft 6 Turn clockwise from its closed position shown in its open position, since the slider at the end of acting as a crank sliding arm 7 is moved on a corresponding circular path and to compensate for the different swing lengths of lever arm 7 and rotary wing 2 in the slide rail 8th along slides. By appropriate turning back the drive shaft 6 Clockwise, the rotary wing can be 2 close again and is then back in the position shown.

In the illustration after 2 the drive mechanism is shown schematically, through which the drive shaft 6 for opening and closing the rotary wing 2 can be turned.

In the case 5 is on the drive shaft 6 opposite end of an electric drive motor 9 which may in particular be a geared motor. From the motor shaft 10 , which are axially parallel to the central longitudinal axis of the housing 5 runs, can be a drive screw 11 be rotated, the worm gear in the teeth of a worm wheel 12 combs. The worm wheel 12 is in meshing engagement with other gears 13 and 14 , where the gear 14 in a not shown in detail transmission device 19 intervenes. By means of the transmission device 19 can the rotational coupling of the gear 14 with the drive shaft 6 be effected. On the other hand, can also be a decoupling of gear 14 and drive shaft 6 be made via a non-visible freewheel. In addition, the transmission device includes 19 nor a switching device similar to a mechanical transmission through which the direction of rotation of the drive shaft 6 despite the same direction of rotation of the gear 14 can be reversed.

Laterally next to the gearbox 19 is located in the housing 5 a cylindrical tube sleeve 16 , In the hollow chamber of the tube sleeve 16 is a coil compression spring 17 , whose winding diameter is slightly smaller than the clear diameter of the pipe sleeve 16 itself. One end of the spring winding is supported on an annular end face of the tubular sleeve 16 from, while at the opposite end of the spring winding a spring plate 18 is supported. Between ring end face of the pipe sleeve 16 and the spring plate 18 is the helical compression spring 17 by means of a force transmission element 15 held in a largely expanded position in which it extends over most of the tube length. The power transmission element 15 consists of a wire rope or a flexible band that rotates with the gear 13 entwined drum or the like., Is attached to one end. From the drum partially enclosing end, the force transmission element extends 15 through the open end of the tube sleeve 16 in the hollow chamber, passes through the spring winding of the helical compression spring 17 lengthwise and then the spring plate 18 to which the power transmission element 15 is attached by means of a nipple or the like with the other end.
