US Patent 9879455 Slip resistant glass hinge system

A slip resistant hinge system for doors and, in particular, frameless glass doors, is provided. The hinge includes a dovetail-shaped central raised portion that minimizes or prevents the possibility of the glass slipping when secured to the hinge. The dovetail-shaped central raised portion can be designed as part of the hinge or can be created by inserts positioned around the central raised portion of the hinge. In operation, a corresponding dovetail-shaped opening is cut into the door for receiving the hinge.
