Problems solved by technology

[0003] The use of blinds with a clutch control mechanism has the following problem, that is, when lowering the blinds, the user sometimes tries to lower the blinds by pulling down the lower rail instead of using the control cord to lower the blinds
And when the user pulls down on the lower rail to force the curtain to close in this way, it will cause irreparable damage to the clutch mechanism.

Embodiment Construction

[0026] The invention has many different embodiments. The embodiments and drawings disclosed here are only to illustrate the technical features of the present invention. The disclosed embodiments and descriptions are intended to illustrate the features and techniques of the present invention, and the scope of the present invention is not limited to these descriptions or embodiments.

[0027] Please refer to FIG. 1 , which shows a honeycomb shade 10 . The honeycomb shade 10 includes an upper rail 12, a light blocking element such as a honeycomb structure 14, a lower rail 16, a control rope 18 and a plurality of hanging ropes (not shown). The honeycomb shade 10 can be opened by raising the lower rail 16 towards the upper rail 12 so that the honeycomb structure 14 shrinks and converges on the lower rail 16 . The lifting action of the lower rail 16 can be achieved by the user lifting the lower rail 16, which in turn causes the clutch mechanism (FIG. 2) to wind the suspension rope...

Abstract

The present invention provides a window covering with a control mechanism for raising and lowering the window covering. The control mechanism provides a separator system. More particularly, the present invention relates to a control mechanism having a separator system that provides a disconnect function to prevent or reduce damage to the control mechanism due to inadvertent force applied to the window covering. The decoupler system has a body movable between an engaged position in which the clutch axle and winding axle move simultaneously, and a disengaged position in which the winding spool It is then independently rotatable relative to the clutch axle.

Description

technical field [0001] The present invention relates to a curtain utilizing a separator system on a curtain control mechanism. The present invention particularly relates to a control mechanism for curtains, which can provide or have a separation function to avoid or reduce damage to the control mechanism caused by the force exerted on the curtain inadvertently by the control mechanism. Background technique [0002] Drapes are available in many different forms. For example, such as Venetian blinds, Roman blinds and honeycomb blinds. Common curtains mostly include an upper rail, which has a light-shielding element suspended from the upper rail by a hanging rope. These shades also typically include a lower rail, which is also suspended from the upper rail to provide additional weight to extend and straighten the light blocking elements. The positioning of the lifting rope can be adjusted by different mechanisms, such as rope locks, clutches and winding drums. For example, f...
