Frequency dampening mounting system

A vibration isolating damper for securing a first structure to a second structure, and comprising:

• a primary isolator of elastomeric material configured to engage the first structure for securement thereto and including a tubular body and a shoulder adjacent to an axial end of the tubular body, the shoulder extending radially inwardly to partially close the axial end of the tubular body;
• a fastener having a rod portion extending through the tubular body of the primary isolator and configured for securement to the second structure;
• a rigid tube disposed about the rod portion of the fastener and extending through the tubular body of the primary isolator;
• and
• a coil spring disposed about the rigid tube and engaging the shoulder of the primary isolator within the tubular body,
• wherein the primary isolator further includes:
• a tubular extension that extends beyond the shoulder away from the tubular body, an annular extension that extends radially outwardly from an end of the tubular extension spaced apart from the shoulder, and a bumper extension extending from the annular extension away from the tubular body, and
• wherein the bumper extension defines a plurality of upper recesses at regular angular intervals.

• wherein the primary isolator further includes an inner tubular portion extending in an axial direction from the shoulder and located between the coil spring and the rigid tube, and
• wherein the inner tubular portion, the shoulder, and the tubular together define a pocket that receives an upper end of the coil spring.
