Abstract
Isolator devices to isolate equipment from vibration and/or shock. The isolator devices may include a helical coil with circumferentially distributed bars disposed thereon. The bars may include a first bar that couples to equipment to be isolated from vibration and/or shock, a second bar that couples to a support surface that experiences vibration and/or shock, and intermediary bars. The intermediary bars may be disposed circumferentially between the first and second bars to add increased stiffness to the helical coil.
Claims20
An isolator device configured to isolate equipment from vibration and shock experienced by a support surface, the isolator device comprising:
- a coil comprising a central longitudinal axis;
- a first bar and a second bar, the first bar configured to be coupled to the equipment and the second bar configured to be coupled to the support surface such that the isolator device is disposed between the equipment and the support surface in a vertical direction to support a load of the equipment;
- and
- a first intermediary bar and a second intermediary bar, wherein widths of the first intermediary bar and the second intermediary bar are smaller than widths of the first bar and the second bar;
- wherein each of the first bar, the second bar, the first intermediary bar, and the second intermediary bar are coupled to the coil and parallel to the central longitudinal axis;
- wherein each of the first intermediary bar and the second intermediary bar are circumferentially disposed between the first bar and the second bar about the central longitudinal axis;
- wherein the first intermediary bar and the second intermediary bar each comprise a length that is less than lengths of the first bar and the second bar;
- and
- wherein the first intermediary bar and the second intermediary bar are positioned at one of two ends of the isolator device and extend to terminate between the two ends of the isolator device.
