ACTUATING DEVICE, ESPECIALLY FOR A SHADING SYSTEM, FOR ACTUATION WITH A STRING ELEMENT

摘要

An actuating device (10) actuates a shading system with a string element (44). An unintended detachment of a first partial structure (12) from a second partial structure (13) in the intended use is avoided as much as possible and a detachment of the first partial structure (12) from the second partial structure (13) is possible with low forces for avoiding injuries. The actuating device (10) includes a first coupling element (26, 27) that in the released position does not mesh with a second coupling element (28, 29), and in the locking position, with an interaction of the first coupling element (26, 27) with the second coupling element (28, 29), a detachment of the first partial structure (12) from the second partial structure (13) is prevented because of a positive-locking connection between the first coupling element (26, 27) and the second coupling element (28, 29).

1. An actuating device for a shading system, for actuation 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 released position for detaching the first partial structure from the second partial structure; and 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 released position by the detachable connection, the first coupling element, in the released 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.
