Title:
エレベータのつり合いおもり装置
Document Type and Number:
Japanese Patent JP4619022
Kind Code:
B2
Abstract:
A balancing apparatus includes a frame body ( 1 ), a first weight ( 2 ) and a second weight ( 3 ) separated from each other vertically in the frame body ( 1 ). The first weight ( 2 ) is connected to the frame body ( 1 ) through elastic bodies ( 41, 42 ). The elastic bodies ( 41, 42 ) are always subjected to compression load. The first and second weights ( 2, 3 ) are accommodated together in the frame body ( 1 ). Since tensional load is not applied to the elastic bodies ( 41, 42 ), the durability of the balancing apparatus can be ensured.
