Kind Code:
A1
Abstract:
The present invention provides a trolley system, having a disengagement prevention structure, of a flexible opening/closing structure, the trolley system comprising: a plate for supporting a cable; and a trolley for folding or unfolding a flexible film while moving on the cable. The trolley comprises: a slider (100) making contact with the cable and moving along the cable; a flexible film coupling member (200) provided below the slider and having the flexible film coupled thereto; and an elastic module (E) provided inside the slider. The elastic module comprises: elastic blocks (10) each having a spring therein, and thus moving in the vertical direction by a predetermined distance by receiving the elastic force of the spring; a top support plate (11) for supporting the elastic blocks from the top; a side support plate (12) for supporting the elastic blocks from the side; and a bottom support plate (13) for supporting the elastic blocks from the bottom, wherein the elastic blocks are provided so as to be vertically movable while the bottom surfaces thereof make contact with the top surface of the plate.
