Actuating device, especially for a shading system, for actuation with a string element

A shading system comprising:

• one of a blind, a pleated blind and a roller blind;
• and
• an actuating device for actuation of the shading system with a string element with a first strand and a second strand, the actuating device comprising:
• a first partial structure;
• a second partial structure, the first partial structure being detachably fastened to the second partial structure, whereby the first partial structure is detachable from the second partial structure with a simultaneous pull on the first strand and on the second strand of the string element when exceeding a predetermined pulling force;
• a first coupling element associated with the first partial structure;
• a second coupling element associated with the second partial structure, the first coupling element, in a locking position, meshing with the second coupling element, whereby the first partial structure, with a pull individually one of on the first strand and on the second strand is pivoted into the locking position, and the first partial structure, with a simultaneous pulling on the first strand and on the second strand of the string element, is pivoted into a release position, the first partial structure being detachable from the second partial structure in the release position;
• a detachable connection between the first partial structure and the second partial structure, whereby the first partial structure and the second partial structure are connected to one another in the release position by the detachable connection, the first coupling element, in the release position, does not mesh with the second coupling element, and in the locking position with an interaction of the first coupling element with the second coupling element, a detachment of the first partial structure from the second partial structure is prevented by a positive-locking connection between the first coupling element and the second coupling element;
• another first coupling element associated with the first partial structure;
• another second coupling element associated with the second partial structure wherein the first coupling elements and the second coupling elements form a first coupling device;
• and
• a second coupling device, separate from the first coupling device for establishing an additional connection of the first partial structure with the second partial structure in a locking position with a pull on a single strand, whereby two connections between the first partial structure and the second partial structure are simultaneously established with the pull on the pull on the single strand.

An actuating device for a shading system, the actuating device comprising:

• a string element comprising a first strand and a second strand;
• a first partial structure;
• a second partial structure;
• a first coupling element associated with the first partial structure;
• a second coupling element associated with the second partial structure, the first partial structure being movable, relative to the second partial structure, between a release position and a lock position, wherein the first partial structure is pivoted via a force applied on one of the first strand and on the second strand such that the first partial structure is pivoted into the lock position, the first coupling element being in direct contact with the second coupling element with the first partial structure in the lock position and the first partial structure being connected to the second partial structure with the first partial structure in the lock position, wherein a detachment of the first partial structure from the second partial structure is prevented by a positive-locking connection between the first coupling element and the second coupling element with the first partial structure in the lock position, the first partial structure pivoting from the lock position to the release position via another force simultaneously applied on each of the first strand and the second strand, the first coupling element being located at a spaced location from the second coupling element in the release state and the first partial structure is detachably connected to the second partial structure with the first partial structure in the release position, wherein the first partial structure is detachable from the second partial structure with the first partial structure in the lock position with a simultaneous pull on the first strand and on the second strand of the string element when exceeding a predetermined pulling force.
