Foundation shock eliminator

Abstract

A foundation shock eliminator for buildings or machines to dissipate or eliminate shock energy includes an upper block, a lower stationary base, a roller and an energy damping coating. The upper block and the lower stationary base have respectively a concave inner surface. The concave inner surfaces face each other. The roller is mounted between the concave inner surfaces. The energy damping coating dissipates the shock energy and is covers at least one of the surfaces of the upper block, the lower stationary base and the roller. Consequently, the foundation shock eliminator will aid the buildings or the machines to resist both vertical and horizontal shocks and diminish the shock effects to the buildings or machines. The energy damping coating will keep the entire foundation shock eliminator from being unstable whether or the foundation shock eliminator is subjected to shocks.

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 that introduces a moveable, passive damping element to dissipate shock energy efficiently. [0003] 2. Description of Related Art [0004] Vibration control and shock reduction are fundamental concerns in the construction of buildings, machines and industrial manufacturing instruments. Diminishing the effect of shocks on objects is achieved primarily by isolating the shocks or absorbing the shocks. [0005] In electronic industries, manufacturing electronic products such as semiconductor wafers and integrated circuits uses sophisticated processes that must be kept stable. Shocks will influence the fabrication of the electronic products adversely. Therefore, reducing the effect of shock on manufacturing machines in electronic industries is always an important concern.

AI Technical Summary

Benefits of technology

[0014] The main objective of the invention is to provide a foundation shock eliminator with a damping element to efficiently dissipate shock energy to reduce the effect of shock on machines and buildings.

[0015] A foundation shock eliminator in accordance with the present invention to dissipate or eliminate shocks transmitted to buildings and machines includes an upper block, a lower stationary base, a roller and an energy damping coating. The upper block and the lower stationary base have respectively concave inner surfaces that face each other. The roller is mounted between the concave inner surfaces, rolls on the concave inner surface of the lower stationary base and supports the concave inner surface of the upper block. The energy damping coating dissipates shocks and is coated on at least one of the upper block, the lower stationary base and the roller. Consequently, the foundation shock eliminator will resist both vertical and horizontal shocks and diminish the effect of shock on the buildings and machines. The energy damping coating will keep the entire foundation shock eliminator from being unstable whether the foundation shock eliminator does or does not undergo shocks.

Problems solved by technology

Shocks will influence the fabrication of the electronic products adversely.

However, the conventional foundation shock eliminator cannot diminish the effect of shocks transmitted through the ground or the floor enough to keep the buildings from collapsing or the machines from being influenced adversely by the shocks.

Since the roller contacts each of the concave inner surfaces at a point and the concave inner surfaces are curved and slippery, the roller slips or rolls easily on the concave inner surface of the lower stationary base when no shock is applied to the foundation shock eliminator.

The entire foundation shock eliminator becomes unstable because of self-induced displacement of the roller by the machine or the building.

The conventional foundation shock eliminator cannot dissipate the shock energy efficiently so the undiminished shocks may damage the buildings or the machines.

Moreover, the conventional foundation shock eliminator only reduces the horizontal component of shocks and does nothing to reduce the vertical component of shocks.

Therefore, the applications and usage of the conventional foundation shock eliminator are restricted.
