Abstract: The present invention relates shortly to an angular gear (1) for use in venetian blinds for angular adjustment of the venetian blind laths from a place beside the venetian blind. The angular gear (1) consists of three parts, a gear housing (2), a shaft (3) provided with a helical gear (10), and a pinion (4), the shaft (3) being provided with or constituting an operating means and a pinion (4) meshing with the helical gear (10) being anchored to the shaft suspending the venetian blind laths, by the aid of ladder bands attached to the shaft. The shaft (3) is provided with at least one bearing portion of circular cross section and this bearing portion cooperates with a complementary bearing portion in the gear housing (2).

Abstract: The present invention relates to a bearing bracket for outer-wall Venetian blinds. The bearing bracket comprises a lifting roll (4) and a turning roll (13), these rolls being connected by a coupling (11, 19, 20) which during rotation of the lifting roll (4) in varying directions causes the turning roll (13) to be moved to various predetermined positions of adjustment for the skewing of the blind laths. The predetermined positions of adjustment corresponding to a completely open, completely closed and slightly open Venetian blind. The coupling (11, 19, 20) comprises a ratchet wheel (11) having two rows of ratchet teeth and two pawls (19, 20) for cooperation with one row each of ratchet teeth on the ratchet wheel (11). When rotating the lifting roll (4) the turning roll (13) is carried to the position corresponding to the predetermined positions of adjustment for the skewing of the blind laths.

Abstract: Ball cord lock intended to be used for roller blinds and comprising a cord pulley having an axially extending stub axle for receiving and retaining one end of a roller blind rod, an endless ball cord arranged around the cord pulley and in engagement therewith and which during operation windsup and unwinds respectively a blind attached to the roller blind rod, a lock housing formed by two complementary housing halves which housing constitutes journal for and encloses the cord pulley, a bracket which is connected to the lock housing and which is intended to be mounted at a window, and a U-shaped cord locking portion formed in the lock housing for catching and retaining one of the loops of the ball cord whereby the rotation of the cord pulley in one direction and accordingly unwinding of the blind in wound-up condition is prevented. The U-shaped cord locking portion is arranged immediately adjacent the periphery of the cord pulley under one of the freely suspending loops of the ball cord.
