Abstract: A door operator for operating a swing leaf in a door assembly. The door operator is configured to be mounted to a reception body such as a door transom, a wall or the like, and has a connector module for connecting with at least one connecting line. The connector module from a direction of the reception body and from at least one lateral direction, has at least one opening, through which the connecting line can be optionally guided to the connector module.

Abstract: A door operator to be disposed at a door leaf, a door frame, a door transom, or a wall, with at least one mounting plate, on which the door operator assembly is disposed. The assembly has a modular design and has at least one connector module, a drive module and a main module, which are latched onto the mounting plate by latching elements. The main module includes a system carrier, which accommodates at least one supply unit and at least one control unit, fastened by latching elements.

Abstract: A door operator with at least one base element, a first and a second front element and two lateral elements, the base, front, and lateral elements being interconnected and at least one of the elements being configured with a breakthrough for the passage of electrical connecting elements. At least one of the base, front, and lateral elements is disposed at the base element to be foldable.

Abstract: The invention relates to a door drive with a motor-gear-unit and with a spring (7), which acts as an energy accumulator. With the intention to provide a door drive, in which, through the exchange of a single structural component, two variants for scissor arm assemblies, respectively slide channel arm assemblies are realized, according to the invention, it is provided that the pre-loading of the spring (7) can be actively changed by the motor-gear-unit, whereby the desired closing moment characteristics are generated.

Abstract: The invention relates to a device for opening and/or closing a door comprising an electric motor and other electrical, mechanical, and/or hydraulic driving elements as well as a support (50) for accommodating the driving elements. The aim of the invention is to create a device for opening and/or closing a door in which the entire drive unit can be assembled using a few manipulations such that the drive can be serially produced with little effort. Said aim is achieved by plugging a preassembled motor-gear unit (20), a conductor card (30), and a harness with a transformer (40) into the support (50) and electrically interconnecting the same by means of a connecting plug (45).

Abstract: A hydraulic door drive includes a working piston and an auxiliary separated by a spring in a common piston space. A hydraulic circuit connects a first pressure space on a side of working piston facing away from the spring, and a second working space on a side of the auxiliary piston facing away from the spring. A power and control unit controls the pressure generated in the hydraulic circuit by a motor driven pump based on the position of the working piston, as determined by a position transducer.

Abstract: A door leaf actuator includes a system carrier on which a door closer and other components are arranged. The door closer is arranged in such a way that its drive axle lies as close as possible to one end of the system carrier. In this way, a door leaf drive is provided which is constructed in a simple manner and is easy to service but which nevertheless has only small dimensions.
