摘要

PURPOSE: To smooth and synchronize the movement of each wall plate to improve the appearance and improve productivity and workability of a wall device having a plurality of wall plates and having the function of regulating acoustic effect by the postures of the wall plates. ;CONSTITUTION: A required number of rectangular wall plates 10 are rotatably provided on collar-like frames 11, 12, 13 capable of being embedded in wall surfaces so that the end parts of the adjacent wall plates make contact to each other, and driven members 29 are mounted on the wall plates. Driving units 14 are provided on one end side of the frames, and driving members 32 are mounted on the shafts driven by the driving units 14. The driving members 32 are connected to the driven members 29 by bar transmission members 31, and the driving members 32 are rotated by the driving units 14, whereby each wall plate is synchronously rotated through the transmission part and the driven member.;COPYRIGHT: (C)1994,JPO&Japio
