Title:
MOVABLE WALL
Document Type and Number:
Japanese Patent JP3234554
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the bending stress from being applied to a wire.
SOLUTION: The movable wall is formed in structure, in which a sealing body installed at the lower end of a wall body moved along a rail in a freely projecting-retreating manner is urged in the direction that the sealing body is projected by a spring and an operating device sinking the sealing body is mounted on the wall body. The operating device has a wire 17 stretched to the wall body and linked with the sealing body, a rack 26, which is laid on a base 21 fixed onto the wall body in a freely linear-motion manner and to which one tip of the wire 17 is retained, a pinion 29 rotatably supported to the base 21 and engaged with the tooth row 27 of the rack 26, a handle for rotating the pinion 29, and a ratchet 34 being engaged with the tooth row 27 of the rack 26, preventing the motion in the projecting direction of the rack 26 and releasing the preventing state by operation at that time. Accordingly, since the rack 26, to which the wire 17 projecting and retreating the sealing body is retained, conducts only a linear motion, the repeated bending stress applied to the wire 17 can be obviated.
