Abstract (en)
A Roman blind without any pull rope includes an upper case, a blind cloth, and at least an elastic device. The upper case has a winding shaft in its interior for winding plural ropes attached on an inner surface of the blind cloth for pushing up and down for expanding or shrinking. The elastic device is deposited in the upper case, consisting of a housing and a spring fixed in the housing, a first bevel gear with a shaft and a second bevel gear with a shaft. The first and the second bevel gear engage with each other, and the elasticity of the spring is transmitted orderly to the second bevel gear, the first bevel gear, and to the winding shaft so as to pull up or lower down the blind cloth without necessity of pull ropes. The elasticity of the spring can balance the weight of the blind cloth for keeping the blind cloth stopped at one of many vertical locations.
