Vibration isolation fastener insert

A vibration isolation fastener insert structure adapted to be partially or wholly snugly received in a hole in a panel comprising:

• a rigid cylindrical hub having an externally extending flange and a central through longitudinal opening adapted to receive a fastener element;
• an elastomeric bushing snugly carried or formed around said hub and having a slot therein receiving said externally projecting flange;
• an upper housing;
• a lower housing;
• the upper housing being disposed around the side of said bushing and having a flange over the top of said bushing and the lower housing disposed around the external side of said upper housing and having a flange extending below a lower surface of said bushing, said lower housing being externally threaded.

A panel assembly having a through hole, at least partially snugly received in said hole a vibration isolation fastener insert comprising:

• a rigid cylindrical hub having an externally extending flange and a central through longitudinal opening adapted to receive a fastener element;
• an elastomeric bushing snugly carried or formed around said hub and having a slot therein receiving said externally projecting flange;
• an upper housing;
• a lower housing;
• the upper housing being disposed around the side of said bushing and having a flange over the top of said bushing and the lower housing disposed around the external side of said upper housing and having a flange extending below a lower surface of said bushing,
• the upper housing being disposed around the side of said bushing and having a flange over the top of said bushing and the lower housing disposed around the external side of said upper housing and having a flange extending below a lower surface of said bushing, said lower housing being externally threaded.

A panel assembly, said panel having a through hole, and upper and lower flanges, the upper flange having a cylindrical element being snugly received in said through hole and the lower flange having a cylindrical element being threadably received in said upper flange and carrying inwardly projecting threads,

• a vibration isolation fastener insert structure partially or wholly inserted in said hole in said panel and comprising:
• a rigid cylindrical hub having an externally extending flange and a central through longitudinal opening adapted to receive a fastener element;
• an elastomeric bushing snugly carried or formed around said hub and having a slot therein receiving said externally projecting flange;
• an upper housing;
• a lower housing;
• the upper housing being disposed around the side of said bushing and having a flange extending over the top of said bushing and the lower housing disposed around the external side of said upper housing and having a flange extending below a lower surface of said bushing, said lower housing being externally threaded,
• said external threads on said lower housing being made up with the inwardly projecting threads on said lower flange.
