RESISTANCE DROP DOWN CURTAIN SET

摘要

A resistance drop down curtain set is provided. An open/close state of the curtain set is changed by directly, manually operating a bottom edge of the curtain to provide a design for effectively preventing the curtain from sliding downwards. A thread exit position of a winding element is indirectly provided with a set of damping device. The damping device restrains a downward sliding force of a drawstring, and further stables a lower truss rod of the curtain to be positioned at a position of any desired horizontal height.

1. A resistance drop down curtain set, entirely manually operated to change an open-close state of a curtain, comprising a design that prevents the curtain from sliding downwards, the resistance drop down curtain set including
an upper truss rod, provided with a winding element in an internal vertical space; a feedback device, having a working end being in linked relationship with the winding element; a set of drawstring, having an upper end winded and combined to the winding element, a body penetrated through a curtain, and a lower end combined to a lower truss rod; and a set of damping device, provided in the upper truss rod, comprising a seat, located at a thread exit position of the winding element, the seat combined with a damping wheel, a tread of the damping wheel being winded by the passing body of the drawstring; wherein, the damping wheel one-directionally limits the drawstring from being released downwards, and has a damping force smaller than a force of the manual operation.
