Abstract
The roller-blind bar drive mechanism comprises a pulley working in a housing and round which a chain consisting of spherical links is passed. A locking member works with one of the two falls of the chain, having a U-shaped open portion narrower than the chain links. - This member can be fixed to the housing (12) in two different positions, its working portion (27) being so situated that it can engage with one or the other of the chain falls (22,23). (1) DEAB- DE3001489 C The drive is for a rolling curtain spindle, with a cord pulley for a ball cord. A blocking element, on the case, is an independent component, with a U-shaped blocking piece on one side, acting with a hanging part of the cord. - This element is detachably fastenable on the case (12) in two different settings. It can be selectively turned through 180 deg., and arranged so that its blocking piece (27) acts with one or the other downward-hanging part of the cord (22,23).
