Abstract: Included are: a screen member 33: a fitter member 35 attached to a side end 33a of the screen member 33; a rail member 91 having a first chamber 91a and a first slit 91b joining the first chamber 91a, the first chamber 91a accommodating the side end 33a of the screen member 33 and the fitter member 35 passing through the first slit 91b to thereby allow the rail member 91 to hold the screen member 33 movably in a longitudinal direction of the first slit 91b; and a retainer 93 for retaining the rail member 91. The rail member 91 is compressively deformed in the width direction of the first slit 91b by the retainer 93, and the width of the first slit of the compressively deformed rail member 91 is narrower than the thickness T1 of the fitter member 35.

Abstract: A screen apparatus X1 includes: a screen member 22; an inner guider 60 extending in a vertical direction of the screen member 22 and holding a side end 22a of the screen member 22 movably in the vertical direction of the screen member 22 while regulating a displacement of the screen member 22 in a lateral direction of the screen member 22; and an outer guider 50 extending in the vertical direction of the screen member 22 and having a recess 54 for accommodating the inner guider 60, wherein the outer guider 50 holds the inner guider 60 dismountably from the recess 54 in the lateral direction of the screen member 22.

Abstract: In a roll screen device, inner rails are embedded inside fixed guide rails which guide protrusions at side edges of a screen which is wound via a take-up shaft. Each inner rail has a guide groove in which the guide protrusion is inserted, and inward flanges are provided at an opening of the guide groove. Rail members have outer side protrusions and inner side protrusion of different heights at both side edges of a rail base plate. The higher outer side protrusions are confronting. A micro gap extends between the lower inner side protrusions into the guide groove such that the micro gap is opposed to a guide gap formed between the opposed inward flanges. The guide protrusion is slid and guided in a come-off preventing state by the inner side protrusion, so that an extremely thin fastener element can be used as the guide protrusion.

Abstract: A screen device includes a pair of parallel side frames, a take-up shaft mounted between ends of the side frames, and a screen wound around the take-up shaft and having a bar secured to its free end. The side frames have guide grooves formed in their opposing sides. The bar has both ends thereof received in the grooves in the side frames. Wires having their leading ends connected to the bar are taken up by a wire take-up drum. A constant force spring urges the wire take-up drum to rotate in such a direction that each wire is wound around the wire take-up drum, thereby applying tension to the screen.
