SLAT SWINGING MECH AND OPENING COVERNING DEVICE USING THE SAME

摘要

The operability of a swinging mechanism for swinging slats is improved, and the functions such as circulation, ventilation, and day−lighting by an opening covering device are enhanced by the winging mechanism. Slats (2) are arranged horizontally in a rain shutter door frame composed of upper and lower stiles (10, 11), left and right rails (12, 13), and a central stile (14). An operating slider (15) for operating the swinging mechanism faces to the central stile (14). The sliding force of the operating slider (15) is converted to a rotational force by a torsion bar (3) and transmitted to the slats (2) through a first transmitting member (5), a bar member (4), and a second transmitting member (6).
