SELF-ALIGNING COUPLER FOR SUPERPOSED SURFACES AND METHOD OF SELF-ALIGNING COUPLER FOR SUPERPOSED SURFACES

摘要

Self-aligning couplers and methods for aligning superposed surfaces include a circular and semi-spherical base formed on a first surface, a fastening element perpendicularly passing through the circular and semi-spherical base and associated to a second surface, and at least a semi-spherical insert disposed on the circular and semi-spherical base and concentric to the fastening element. The semi-spherical insert is cooperative with the circular and semi-spherical base and the fastening element for the self-alignment and superposed fastening of the first and second surfaces.
