Device for controlling the actuation of a group for moving a curtain/awning

摘要

A device for actuating a curtain/awning in a double glazing includes a pulley supported by support elements connected to connection elements integrally connected to a wall of the double glazing at the movement group. A ring of cord is partially wound around the pulley and is maintained taught by a tensioning element, it too connected to the wall of the double glazing. By applying a tension to the cord ring, a torque is generated tending to rotate the pulley. The torque is transmitted by suitable transmission elements to the group for moving the curtain/awning. The support elements of the pulley are separated from the connection elements for values of tension applied to the cord ring that are greater than a pre-established limit value. The separation cancels the tension of the cord.

主权项

1. A device (7) for moving a curtain/awning (5) housed in a double glazing (1), the curtain/awning (5) comprising slats (6) located within and translatable within the double glazing (1), said device (7) comprising:
a cord (8) that defines an endless ring, the cord (8) having two cord sections (8a, 8b) that define a first cord section (8a) extending parallel to a second cord section (8b), wherein applying a force to one of the two cord sections (8a, 8b) generated a torque that moves the one cord section in a first direction and moves the other cord section in an opposite, second direction, the cord being located on a first exterior side of a first glass pane (3) of the double glazing; a tensioning element (9) connected to the first exterior side of the first glass pane (3) of the double glazing, a lower distal end of the endless ring defined by the cord (8) being retained within the tensioning element (9) with the first and second cord sections (8a, 8b) extending upward from the tensioning element (9), wherein the tensioning element (9) covers the lower distal end of the endless ring defined by the cord (8) and conceals the lower distal end of the endless ring from exterior view; a connection element (11) integrally connected to the first exterior side of the first glass pane (3) of the double glazing; and a container (10) connected, via the connection element (11), to the first exterior side of the first glass pane (3) of the double glazing with the connection element (11) located between the container (10) and the first exterior side of the first glass pane (3), an upper distal end of the endless ring defined by the cord (8) being retained within the container (10) with the first and second cord sections (8a, 8b) extending downward from the container (10) to the connection element (11), wherein the container (10) i) covers the connection element (11) and ii) covers and supports the upper distal end of the endless ring defined by the cord (8) and conceals the upper distal end of the endless ring from exterior view, wherein the endless ring defined by the cord (8) is rotatable between the container (10) and the connection element (11) and the torque, generated from applying the force to one of the two cord sections, causes translation of the slats (6) of the curtain/awning (5) housed in a double glazing (1), and wherein the connection element (11) disconnectably supports the container (10) such that i) when a value of tension applied to at least one of said two cord sections (8a, 8b) that is lower than a pre-established value, the connection element (11) supports the container (10), and ii) when the value of tension applied to the at least one of said two cord sections (8a, 8b) exceeds the pre-established value causes separation of the container (10) from the connection element (11) by translation of the container (10) with respect to the connection element (11).
