Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a foundation shock eliminator, and more particularly to a foundation shock eliminator having a static supporting device to keep a passive damping device from deforming and wearing to dissipate shock energy efficiently.

[0003] 2. Description of Related Art

[0004] To diminish effect of shocks on objects, construction of buildings, machines and industrial manufacturing instruments, a fundamental shock eliminator is always provided. A conventional foundation shock eliminator in accordance with prior art is generally mounted under the foundation of machines or buildings and substantially comprises an upper base, a lower base and a roller. Two concave inner surfaces are defined respectively in the upper base and the lower base and face to each other. The roller is rotatably mounted inside the concave inner surfaces of the upper base and the lower base. In addition, a damping device is mounted between the upper base, the lower base and the roller and is made of a resilient material with a damping coefficient to absorb shock, reducing the movement range of the roller and eliminating vertical vibration energy.

[0005] However, the damping device must bear the weight of the upper base and the object applied to the upper base, the damping device is easily worn or became compression set so that the shock-absorbing effect of the foundation shock eliminator is reduced. In addition, to replace a worn or deformed damping device with a new one is time consuming and costly.

[0006] To overcome the shortcomings, the present invention provides a foundation shock eliminator to mitigate or obviate the aforementioned problems.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[0038] With reference to FIG. 1, a foundation shock eliminator in accordance with the present invention can be used to diminish shock transmitted to manufacturing machines in electronics factories, such as wafer manufacturing factories and hospital instruments and can be applied between a raised floor (60) and a concrete floor (50).

[0039] The foundation shock eliminator in accordance with the present invention comprises an upper base (20), a lower base (10), at least one roller (30), a damping device (40) and a static supporting device (12).

[0042] The damping device (40) is mounted on at least one of the upper base (20), the lower base (10) and the at least one roller (30) and can be made of rubber, plastic, viscoelastic materials, frictional materials or materials with an excellent damping coefficient. In the first embodiment, the damping device (40) is at least one coating layer (40A) coated around the roller (30).

[0043] The static supporting device (12) is mounted between the upper base (20) and the lower base (10) and comprises multiple supporting members.
