Abstract
A vibration isolator including a bearing support and an elastic member that communicates with a vibration source. The elastic member is capable of bending from an original position to assume a more or less bowed position in response to changes in a load applied to the midportion of the elastic member intermediate its ends and returning essentially to its original position when the original load is restored. The elastic member engages a friction-resistant bearing surface on the bearing support at a distance spaced from each of its ends and moves relative to the bearing surface in response to a bending of the elastic member. The apparatus may be tuned to effectively isolate a particular vibration frequency, for example, by altering the properties of the elastic member or by changing the distance between the points on the bearing support that engage the elastic member.
