JPS6425810A - Curtain driving apparatus - Google Patents

Abstract

PURPOSE: To allow a curtain to move smoothly and prevent generation of uncomfortable sounds such as frictional sound by furnishing a curtain driving device with a plurality of rollers having shafts perpendicular to the sucking direction, and guide rails for guidance of rollers on the side of curtain rail. CONSTITUTION: Shafts 33... are inserted rotatably in bearings 32... installed in front of and behind the oversurface and undersurface of a core base 60. Each shaft 33 is fitted with a stopper 33a in the middle part, and in the foremost part, a roller 31... is fitted rotatably. Thereby the shafts 33... are positioned perpendicularly to the sucking direction, and the rollers 31... can glide on guide rails 30. In this manner, the core base 60 is furnished on the moving part 8 to permit easy mounting of the rollers 31..., so that the sliding resistance in movement is reduced to a great extent. A horizontal supporting arm 17 is installed extendedly at the bottom of the core base 60 rigidly, and on this arm 17 the foremost part of a curtain K is supported whose tail is fixed to the end of the curtain rail 2, and thereby the curtain K can be opened and closed with movement of the moving part 8.
