Handlebar mounting device

A handlebar mounting device, comprising:

• a pivot arm, comprising a connector base and a coupler interface with therebetween a pivot joint having an adjustable rotational stiffness, the pivot joint further comprising:
• a support arm extended from one of the connector base and the coupler interface and having an aperture formed therethrough,
• a hub extended from a different one of the connector base and the coupler interface and having a bore therethrough,
• a pivot pin axially extended between the aperture through the support arm and the bore through the hub with at least one of the support arm and the hub being rotatable about the pivot pin,
• an elastomeric interface substantially entirely positioned between opposing axial surfaces of the support arm and the hub and axially compressible thereby, the elastomeric interface being seated in one of the opposing axial surfaces of the support arm and the hub, and
• a means for axially compressing the elastomeric interface between the opposing axial surfaces of the support arm and the hub;
• a part-spherical coupler component formed on the coupler interface;
• and
• a connector adapted for securing the connector base to a mirror mount receiver on a handlebar where a mirror mounting stem supporting a minor normally resides.

A handlebar mounting device, comprising:

• a pivot arm, comprising:
• a connector base comprising a pair of support arms extended above the connector base and forming a yoke with a pair of clearance apertures mutually aligned between the pair of support arms,
• a coupler interface comprising a barrel hub positioned between the pair of support arms of the yoke with a central bore formed therethrough and having a part-spherical coupler component extended therefrom on a neck portion,
• a pivot pin extended axially through the clearance apertures of the pair of support arms of the yoke and extended axially through the central bore of the barrel hub therebetween,
• a resiliently compressible elastomeric interface substantially entirely positioned between cooperating axial interface surfaces of the barrel hub of the coupler interface and at least one of the support arms of the yoke axially aligned therewith, the elastomeric interface being seated in one of the cooperating axial interface surfaces, and
• a means for axially compressing the support arm of the yoke relative to the barrel hub with the elastomeric interface there between, whereby the elastomeric interface is compressible between the cooperating axial interface surfaces of the barrel hub of the coupler interface and the support arm of the yoke;
• and
• a connector adapted for securing the connector base to a minor mount receiver on a handlebar where a mirror mounting stem supporting a minor normally resides.
