Ball joint pivot for window - has perpendicular screws to allow continuous universal adjustment in window plane

摘要

The L-shaped bracket (10) is screwed to the corner of the window wing. The bracket incorporates the socket of the ball joint on which the window pivots. The other part of the ball joint is mounted on a bracket (11) fixed to the blind frame. A screw (28) provides for vertical adjustment of the window and a further screw (22") operates a cam which causes horizontal movement of the ball. Adjustment of the window wing in any direction parallel to the plane of the window is possible by turning the screws (22", 28) in combination.
