Abstract

271,489. Schultes, P. May 21, 1926, [Convention date]. Roller-blinds, spring.-In a, tensioning-device for spring roller-blinds having a, shaft borne loosely within a hollow blind-roller and a spring around the shaft tensioned between the roller and the shaft, the hollow roller and the shaft are normally uncoupled so that the roller is under control of the spring, but can be coupled together to lock the spring by an outer axially-slidable coupling. As shown, the coupling comprises a disc h slidable on a squared outer end f on the shaft e and carrying on its outer face pins n adapted to enter holes o in an end disc l of the hollow roller d. A cylindrical flange on the disc h engages over a bush p on the window frame and can be secured thereto by means of a bayonet-joint, a spring r pressing the disc outwards. To tension the spring m while the blind is in position, the blind is pulled down, the coupling engaged, the blind wound up by hand, and the parts again disengaged, the operation being repeated until the desired tension is obtained.
