Title:
VIBRATION ABSORBING LEG BODY AND VIBRATION ABSORBING BASE
Document Type and Number:
Japanese Patent JP2008267447
Kind Code:
A
Abstract:

To provide a vibration absorbing leg body and a vibration absorbing base performing flexible shock absorbing operation with a load change to produce a stable spring constant over a long stroke.

The vibration absorbing leg body 2 comprises an air spring 7 as a shock absorbing mechanism using air elasticity for suppressing vibration between a floor B as a supporting body and equipment A as a supported body. The sir spring 7 consists of rubber shock absorbing parts 5, 6 each having an annular vibration absorbing rubber 12 fitted into an annular groove for imparting tensile force to the supported body to be moved up with depressurization. The plurality of vibration absorbing leg bodies 2 are arranged to form the vibration absorbing base 1 which uses the vibration absorbing leg bodies 2 for supporting a placement plate 3 for the equipment A. With a load increased, air is depressurized while being elongated instead of being compressed. Thus, shock is stably and flexibly absorbed over a long stroke in any directions by the vibration absorbing rubbers 12 of the rubber shock absorbing parts 5, 6, to produce self position restoring performance.
