Embodiment Construction

[0044] figure 1 Shown is an apparatus 100 comprising a tubular actuator 1 for controlling a device for safety closing, privacy protection, sun protection or screening. The tubular actuator 1 comprises a fixed end or head 2, a tubular body 3 and an output shaft 4 movable in rotation about a central axis XX' of the tubular body 3, which is horizontal when the system is in operation. The output shaft 4 is connected to a winding tube 5 in which the actuator is engaged by means of a drive wheel 6 . Bearings 7 guide the winding tube in rotation on the tubular body of the actuator. A mounting attachment 8 connects the fixed end 2 to a frame member 9, such as a window frame. A windable element 10, shown in dashed lines, is connected by one end thereof to the winding tube and serves to screen the window when it is unrolled. The windable element may be a blind, shade, commercial mesh, fabric, or cord or any other movable covering for privacy or secure closure.

Abstract

The actuator has an asynchronous motor for providing a set of movements to a kinematic chain, and a reducer. An output transmission shaft is arranged for transmission of movement provided by the motor. An input part (60) and an output part (70) are movable with regard to each other with a limited play. An obstacle generation device includes a set of cams (72-1, 72-2) that is ready to create a transitory resistant force for movement transmission between the input part and output part. A control unit detects the transitory resistant force. An independent claim is also included for a method for checking operation of the electromechanical actuator.

Description

technical field [0001] The present invention relates to the field of electromechanical actuators that can electrically control systems for providing privacy or protection from the sun in buildings, such as curtains or shutters. Background technique [0002] Such actuators drive the movement of the screening element or the screen via a reel, on which a louvered or flexible fabric screen is wound directly or, especially in the case of so-called pleated or venetian blinds, where a cord is attached to the on the free end of the screen. Actuators must meet certain criteria in order to function optimally. Specifically, the actuator must have information about the position of the screen and must be able to stop at a specific position. [0003] A further favorable criterion, especially with regard to roller shutter screens, is that the shutter screen can be stopped at any point in the path of motion due to obstacles in the path of the shutter. [0004] In existing systems and ins...
