Problems solved by technology

Although there are very few slippery parts (generally about 1 / 4 inch to 1 / 2 inch), for the curtains that open and close from top to bottom, this distance is enough to cause improper contact between the light blocking element and the top rail. create a gap
In addition to hindering the blinding function of the curtain, the gap also causes a defect in the aesthetics of the curtain

Embodiment Construction

[0043] Referring to FIGS. 1 and 2 , a top-to-bottom opening and closing curtain includes a top rail 15 and a light blocking element 18 . The light blocking element 18 includes one or more movable shades for blocking or allowing light to pass through, wherein the shades may be in the form of organ shades, Roman shades, venetian blinds or the like. The light blocking element 18 is provided with an upper part (such as the upper rail 16 ) and a lower part (such as the lower rail 17 ). It should be understood that although the illustrated embodiment is provided with an upper rail 16 and a lower rail 17, these elements are not strictly necessary but may be integral upper and lower portions of the light blocking element. The hanging rope 19 is used to control the unfolding operation of the light blocking element 18 , and has one end connected to the upper rail 16 and passes through the hole 30 of the top rail 15 . The suspension rope 19 is also operably connected to the suspension r...

Abstract

A suspension cord control mechanism composed of an arresting mechanism and a biasing mechanism operable to move a light blocking element after the user has released a suspension cord. The biasing mechanism is loaded when the suspension cord is drawn by a user to lift the window covering. When the suspension cord is released, movement of the cord is stopped by the arresting mechanism and the biasing mechanism unloads to further move the light blocking element.

Description

【Technical field】 [0001] The invention relates to a suspension rope control mechanism for a curtain, especially a top-down opening and closing curtain. 【Background technique】 [0002] Blinds with light blocking elements, such as honeycomb panels, are commonly used to control or block light from entering windows and provide privacy. The passage of light is controlled by the operation of opening and closing the light-shielding element. [0003] In order to control the opening and shading operation of the light-shielding element, a common method is to use a bottom-up (bottom-up) weighted rope lock system, which is called because the curtain is pulled up and shortened from the bottom to the top rail. come. The hanging cord is wrapped around a cord lock in the top rail and then attached to the bottom rail of the shade at the other end. The user lifts the bottom of the light-shielding element toward the top rail by pulling down the sling, and then folds the light-shielding elem...
