Problems solved by technology

Here, in order to adjust the spring unit accordingly, a large number of expensive parts are usually required
Although adjustment of the spring force of the spring unit is usually only carried out during assembly of the door operator, the effort required for this entails relatively high manufacturing costs

Abstract

The invention relates to a door driving device, especially a revolving door driving device, the door driving device comprises a housing, a driven shaft capable of coupling with a door leaf or a door frame, a motor and a spring unit for driving the driven shaft, the The spring unit is tensioned during a corresponding opening movement of the door leaf and relaxed during a corresponding closing movement of the door leaf. The driven shaft can be driven by the motor via the rack. The spring unit is supported on the toothed rack on the one hand and on the housing on the other hand via stops which are adjustable relative to the housing for adjusting the spring force of the spring unit.

Description

technical field [0001] The invention relates to a door driving device, especially a revolving door driving device, which comprises a housing, a driven shaft capable of coupling with a door leaf or a door frame, a motor and a spring unit for driving the driven shaft, the The spring unit is tensioned during a corresponding opening movement of the door leaf and relaxed during a corresponding closing movement of the door leaf. Background technique [0002] This type of door operator is used to close the leaf of a motor-operated door with spring force. This is of particular importance for smoke and fire doors, which must be closed quickly and reliably in the event of an alarm, in particular after responding to a smoke alarm or in the event of a power interruption. The spring unit is tensioned simultaneously with opening the door leaf. With the aid of the spring unit, the door operator thus closes the door leaf even in the event of a power failure, which is mandatory in the case...
