Definitions
- a device for absorbing the unwanted energy of impulses or vibrations consisting of a moveable walled vessel or bladder enclosing an elastic material which exhibits viscous damping properties, the material comprising a plurality of capsules made from resilient material or including resilient materials and immersed in a liquid, grease or jelly medium so that when the pressure in the medium increases this pressure increase is hydraulically transmitted to the capsules causing a decrease in the volume of the resilient material and a spatial redistribution of the medium.
- Shock absorbing pads of the material may be incorp ⁇ ated into the hand grips of sports equipment and tools. Such pads would be particularly useful in solving the problem of white fingers (a peripheral circulatory disturbance) by reducing the vibrations transmitted to the users hands by vibrating power tools.
- One advantage of using the present invention instead of existing visco-elastic solid hand grips is that the device can mould itself to fit the grip of the users hand.
- a similar composite material could be used to protect the human body from impacts. For example it could be used in shin pads for footballers.
