Beschreibung
Zusammenfassung:	A shaft lock for interconnection of an elongate tubular lacrosse handle and a plastic lacrosse head. The shaft lock comprises an elastomeric insert compression-fitted inside the handle. The insert has a compressible body portion which, in an uncompressed form generally conforms to the interior walls of the handle and is defined by a plurality of co-planar ribs that span the interior walls of the handle. A hard screw-anchor is embedded within the elastomer insert, and the insert is anchored inside the handle by at least one screw threaded through the handle into the screw-anchor from top-to-bottom, the screw(s) engaging the screw anchor and compressing it against the elastomeric insert. The threaded engagement of the screw(s) through the wall of the handle and into the screw-anchor compresses the elastomeric insert, maintaining a constant tension against the screw(s) and against the interior walls of the handle. This avoids loosening and/or dislodgement as a result of impact or vibration, and resists the threads of the screw from stripping either the handle wall(s) or the insert as a result of torque or other stress.
