Definitions

• the subject of the present invention is a device for manual positioning of a switch in a device for controlling an electric motor of a roller shutter or the like comprising a rod.
• Manual positioning devices of a switch arranged in the structure for example, of a building or in the box containing the motor and the roller shutter are known in particular from patents CH 88338 and FR 2 803 332.
• the user manipulates a rod to control the opening or closing of the shutter. This rod crosses the structure or the box to reach the switch.
• the arrangement of the motor in the structure or in the box, the position of the switch, the rod passage must be adapted, thus creating installation, use, aesthetic or standardization constraints.
• the object of the invention is to improve the devices of the prior art and to provide a simple, inexpensive and space-saving manual positioning device.
• the latitude for positioning on the structure or on the box of the flap of this device must also be wide to allow freedom from installation, use, aesthetics or standardization constraints.
• the manual positioning device according to the invention is characterized in that it comprises a flexible shaft controlled by the rod and transmitting a rotational movement or a translational movement to the switch of the control device and in that it comprises a movement transfer device between the rod and the flexible shaft.
• the movement transfer device can be fixed in the most convenient place for installation, for example, on the building structure or on the box containing the mechanism of the roller shutter or the like.
• the movement transfer device can transform a rotational movement or a translational movement of the rod into a rotational movement or a translational movement of the flexible shaft.
• the rod and the movement transfer device have mutual coupling means making it possible to make the rod removable.
• the flexible shaft may consist of a sheathed or unsheathed cable allowing, according to the embodiments, to transmit a rotational movement or a translational movement to the switch of the control device.
• the movement transfer device transforming a rotational movement into a translational movement or a translational movement into a rotational movement can be carried out in a simple manner by means of an eccentric but also by means of a helical connection or a cam and follower assembly .
• the manual positioning device according to the invention can of course be used to position other bistable mechanisms.
