Abstract: An operating device for a screen comprises: a first operating mechanism with a first operating element which is connected to a first movement transfer element connected by means of a first transmission to a drive element for a screen shaft. The first operating mechanism is configured to convert a linear movement of the first operating element to a rotational movement of the drive element for operating the screen shaft in a first rotational direction. The operating device further comprises a second operating mechanism comprising a second operating element which is connected to a second movement transfer element connected by means of a second transmission to the drive element. The second operating mechanism is configured to convert a linear movement of the second operating element to a rotational movement of the drive element for operating the screen shaft in a second rotational direction opposite to the first rotational direction.

The operating device (1) further comprises a second operating mechanism comprising a second operating element (8) which is connected to a second movement transfer element connected by means of a second transmission to the drive element (60). The second operating mechanism is configured to convert a linear movement of the second operating element to a rotational movement of the drive element for operating the screen shaft in a second rotational direction (L) opposite to the first rotational direction.

Abstract: A motorized drive of a window covering provided with a device for manually operating the motorized drive comprising a housing to be attached to the window covering with a pull cord and a push button for manual operation. A switch converts pulling movements on the pull cord into first electrical signals for the motorized drive. Controls are configured to save a setting value associated with a current position of the window covering in a data memory after receiving second electrical signals from the push button. A method for saving setting values associated with different positions of the window covering provided with the motorized drive comprising the steps of saving a current position by manual operation of the pull cord and/or the push button.

Abstract: The invention relates to a screen, comprising a first control unit (610) comprising a first drive shaft (612) and at least one first cord spool (630) rotatable with the first drive shaft for winding and unwinding a first lift cord (634) extending between a head rail and a middle rail; a second control unit (620) comprising a second drive shaft (622), and at least one second cord spool (632) rotatable with the second drive shaft for winding and unwinding a second lift cord (636) extending between the head rail and the bottom rail; and a shaft rotation limiting system (100) comprising a threaded shaft arranged on and rotatable in unison with one of the first and the second drive shafts, a coupling element threaded on said threaded shaft, wherein the coupling element is associated with and rotatable in unison with the other drive shaft.
