Abstract
A shock-absorbing joint absorbs shock forces by distortion of elastomeric material under torque. One form of the shock-absorbing joint has an inner cylinder fitting within an outer cylinder so as to extend longitudinally beyond each end of the outer cylinder and provide an annular space between the cylinders. A body of elastomeric material, such as rubber, fills the annular space and is affixed to the inside surface of the outer cylinder and the outside surface of the inner cylinder. Inner and outer cylinder pivot members are affixed to the inner and outer cylinder, respectively, and are perpendicular to the common pivot axis of the cylinders. Two or three of such shock-absorbing joints may be used to form a shock-absorbing assembly that is particularly useful in protecting marine platforms.
