Venetian blind having rotatable head assembly
Abstract
Abstract A VENETIAN BLIND INCLUDES A TUBULAR HEAD ASSEMBLY WHICH IS ROTATABLY MOUNTED AT ONE OF ITS ENDS IN A CORD LOCK ASSEMBLY HAVING THEREIN A VERTICALLY MOVABLE LOCKING PIN WHICH AUTOMATICALLY GRIPS AND LOCKS THE CORD WHEN THE LATTER IS RELEASED AFTER THE BLIND HAS BEEN LIFTED. LIFT CORDS PASS THROUGH THE CORD LOCK ASSEMBLY AND INTO THE TUBULAR HEAD ASSEMBLY AND THROUGH SPACED SLOTS IN THE WALL OF THE TUBULAR HEAD ASSEMBLY. TILT CORDS ARE ATTACHED TO THE HEAD ASSEMBLY. ONE END OF THE TUBULAR HEAD ASSEMBLY IS MOUNTED IN A FIRST MOUNTING BRACKET WHICH SUPPORTS THE CORD LOCK ASSEMBLY AND HOLDS IT AGAINST ROTATION. A SECOND MOUNTING BRACKET WHICH SUPPORTS THE OTHER END OF THE HEAD ASSEMBLY HAS MOUNTED THEREIN A TILT GEAR ASSEMBLY, SAID OTHER END OF THE TUBULAR HEAD ASSEMBLY IS SEPARABLY CONNECTED TO THE TILE GEAR ASSEMBLY IN TUBULAR HEAD ASSEMBLY ROTATING RELATION.
