Embodiment Construction

[0022] figure 1 A window covering 1 and a mechanism 2 for controlling the adjustment of the window covering 1 are shown. More specifically, the mechanism 2 controls the movement of the blind 1 onto and away from the cylinder 3 to open or close the blind 1 over a window or the like. It should be understood that the invention is not limited to mechanisms that adjust in this manner only, but that the invention is also applicable to mechanisms that adjust in other ways. Another form of adjustment may be, for example, the adjustment of the direction of rotation of the vertical venetian blind, or the extension and retraction of the vertical venetian blind or window covering along the guide rail.

[0023] figure 1 The shown mechanism comprises a lower part 4 and an upper part 5 separated from the lower part 4 by an elongate member 6 . This upper part 5 comprises a cylinder 3 rotatable about an axis of rotation XX. The elongate member 6 has a longitudinal axis YY which intersects ...

Abstract

A mechanism for controlling adjustment of a blind or the like, the mechanism including, a fixable member which in use is fixed in position relative to the blind, a rotatable member located proximate the fixable member being rotatable relative to the fixable member about an axis of rotation to adjust the blind, an elongate member a proximal end of which is located proximate the rotatable member, the elongate member having a longitudinal axis that intersects the axis of rotation, and a continuous pull element which interacts with the rotatable member, the pull element is movable relative to the fixable member to rotate the rotatable member, the pull element is arranged relative to the elongate member extending from the rotatable member towards a distal end of the elongate member and back towards the rotatable member so as to limit movement of the pull element in a direction substantially perpendicular to the longitudinal axis of the elongate member.

Description

technical field [0001] The invention relates to a mechanism for controlling the adjustment of curtains. This mechanism is used to control the adjustment of jointed roller blinds, and reference is made to this particular application in order to describe the invention below. However, it should be understood that the mechanism is applicable to other window coverings or window covering control mechanisms using tension members such as chains or cords. These blinds can include Venetian blinds and vertical blinds. Background technique [0002] Blinds typically include a length of flexible material that can be positioned adjacent a window or the like. Roller blinds typically include a mechanism for adjusting the position of the material relative to the window. The mechanism includes a cylinder around which the material is wound, which is supported at its distal end. Engaged roller mechanisms include a tension member, such as a chain or rope, at the distal end of the cylinder. T...
