PARALLEL MAINTAINING DEVICE FOR QUAKE-PROOF DEVICE

摘要

PURPOSE:To facilitate assembly and installation by dividing at least two pulleys into one and the other, by placing a wire over these pulleys and by fixing the wire which moves from one to the other of the pulleys to a parallel member. CONSTITUTION:An instrument installation table 1 is supported by a supporting table 3 through a compression spring 2, horizontal force of the supporting table 3 is made quake-proof by a roller 4, and a parallel maintaining device is constituted by a pulley 6, a loop-shaped wire 7 and fixing members 9 and 9'. As parallel is maintained mainly with the pulley and the wire, manufacture and installation are easy.
