Embodiment Construction

[0013] Embodiments of the present invention will be described below with reference to the drawings.

[0014] As shown in FIG. 1 , in a quadrangular curtain frame 1 , respective one ends (upper ends) of a pair of guide rails 3 a , 3 b arranged in parallel and perpendicular to a rectangular cylindrical winding member 2 are connected to the winding member 2 . The frame 4 arranged parallel to the above-mentioned winding member 2 is connected between the other ends (lower ends) of the guide rails 3a, 3b.

[0015] In the same manner as in the past, a cylindrical reel 5 is housed in the winding member 2 and the reel 5 is rotatably supported, and the screen 6 is wound around the reel 5 . The reel 5 is rotated by pulling out the curtain 6, and the coil spring (not shown) incorporated in the reel 5 is twisted and deformed, and the reel 5 rotates the curtain 6 back in the winding direction by the return elasticity of the coil spring.

[0016] A rod 7 parallel to the reel 5 is connected ...

Abstract

The invention provides a roller blind which enables a rod to make parallel translation even when the operational force applied by the roller blind on the rod deflects. The invention is a roller blind of which the blind is pulled out of a roll and furled back therein using a rod. Two ropes pass through the rod, enabling the end of one of the ropes that extends out of one end of the rod to pass through a guide rail and to be fixed on the upper end side of the guide rail, enabling the other end to pass through another guide rail and to be fixed on the lower end side of the other guide rail, and enabling the other end of the other rope that extends out of one end of the rope to pass through a guide rail and to be fixed on the lower end side of the guide rail, and making the end pass through another guide rail and be fixed on the upper end side of the guide rail. The rod is stopped by the binding force applied thereon by two ropes which are under tension and disposed at arbitrary positions on the rod. When the rod is in motion, in order to apply a force to slope the rod, one rope under tension has to be further extended to restrain the sloping, so that the rod is always parallel with the roll for pulling out and furling back the blind smoothly.

Description

technical field [0001] The present invention relates to a roll screen used for a sunshade or the like of a train window. Background technique [0002] Conventionally, such a roller blind is known in which a rod is installed at the front end of a screen wound on a take-up shaft, and both ends of the rod are slidably inserted into a parallel set. In the guide groove of the guide rail, the above-mentioned rod is moved along the guide groove to perform winding and unwinding of the curtain (see JP-A-8-226292). [0003] The above-mentioned roller blinds are often used for sunshading of train windows and the like. [0004] This conventionally known roller blind has a structure in which only the two ends of the rod installed at the front end of the curtain are inserted into the guide groove of the guide rail, so when an operating force for opening and closing the curtain is applied at a position away from the midpoint in the longitudinal direction of the rod, the above-mentioned T...
