摘要

FIELD: theater stage equipment. SUBSTANCE: curtain has two flexible guides 1,2, bolts 3 for tightening and attachment of guides by planks 21 on yokes 10. Sliding contacts formed as round rings 5 are fixed on guides to carry webs 6 of curtain by means of suspensions 6. Contacts are urged to slide by endless drive cable 8 passed around corner pulleys 9, which are mounted on ends of bar 4 through detachable yokes 10. Cable 8 goes around drums with pulling weights 11. Horizontal runs of cable 8 are connected with front contacts. Curtain is provided with split sleeves 13 for supporting middle parts of guide. Sleeves 13 are mounted through detachable yokes 14 on bar, with sleeve recess being oriented downward. Sleeve ends and recess have beveled entry edges 16,17. Guides are retained from falling into slot 12 by couplings 18 with conical ends. Couplings 18 are fixed by restricting members 19 on guides within sleeve. Suspension has spherical support 20 pivotally connected with ring for engagement with split sleeve and coupling during passing through sleeve. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 4 dwg
