Abstract
(EN)
The present invention relates to fabric of a cordless double blind and a device for preventing bending of a lower rotating bar. More specifically, while a lower case is moved downward by the force of a handle part being pulled, a pair of rollers and a lower rotating bar are rotated. The rollers having a smaller diameter than the lower rotating bar prevent the lower rotating bar from rising and at the same time offset the load while rotating in close contact with double fabric, and thus prevent bending of the lower rotating bar or wrinkling of the double fabric.
(FR)
La présente invention concerne du tissu d'un store double sans fil et un dispositif pour empêcher la flexion d'une barre rotative inférieure. Plus spécifiquement, tandis qu'un boîtier inférieur est déplacé vers le bas par la force d'une partie poignée tirée, une paire de rouleaux et une barre rotative inférieure sont mises en rotation. Les rouleaux ayant un diamètre inférieur à celui de la barre rotative inférieure empêchent la barre rotative inférieure de s'élever et de décaler en même temps la charge tout en tournant en contact étroit avec le tissu double, et empêchent ainsi la flexion de la barre rotative inférieure ou le froissement du tissu double.

본 발명은 줄 없는 이중 블라인드의 원단 및 하단 회전봉 휘어짐 방지장치에 관한 것으로 더욱 상세하게는 손잡이부를 당기는 힘에 의해 하단 케이스가 하측으로 이동하면서 한 쌍의 롤러와 하단 회전봉이 회전하게 되고, 하단 회전봉보다 지름이 작은 롤러가 하단 회전봉의 상승을 방지함과 동시에 이중 원단에 밀착되어 회전하면서 하중을 상쇄시켜 하단 회전봉의 휘어짐이나 이중 원단의 구겨짐을 방지하는 것이다.
