MOUNTING STRUCTURE FOR LIGHT CONTROL UNIT OF DAYLIGHTING WINDOW

摘要

PROBLEM TO BE SOLVED: To facilitate mounting and removal of a light control unit on and from a daylighting window, to thereby improve the maintenance ease of the control unit.;SOLUTION: The daylighting window is constructed by erecting an erect frame 1 on the periphery of a daylighting opening formed in a roof surface of a building, and mounting a glass window 2 on the erect frame 1. Then, a mounting fixture 11 is hung from an end of the erect frame 1, and a locking slot 12 is formed in the mounting fixture 11. Further, a locking pine 13 formed at an end of the light control unit 5 is rotatably hooked in the engaging slot 12, and a movable pin 14 having a protrudable tip is slidably mounted at the other end of the light control unit 5, followed by arranging a spring 16 on the movable pin 14, for energizing a fitting portion 15 at the tip of the movable pin 14 in a protruding direction. Furthermore, the light control unit 5 is rotated about an engaging portion between the locking pin 13 and the locking slot 12 until the glass window 2 is almost in parallel with the light control unit 5, and in this parallel state, the fitting portion 15 of the movable pin 14 is rigidly fitted into a fitted portion 17 on the other side of the erect frame 1.;COPYRIGHT: (C)2003,JPO
