Control System for Self Restoring Doors, Gates and Windows
This invention teaches a motion control system for self-closing or self-opening pivot hung doors, gates and windows being disposed within a hollow chamber of a pivot hung door, gate or window connected to the door surrounding structure only at the door pivots. The system stores elastic strain energy as the door is displaced from its nominal position and controllably releases that energy to self restore the system to its nominal position. The system consists of serially connected torsion means and dampening means wherein torsion means includes a torsion bar and a torque modulator, and dampening means includes a housing and a rotor operatively rotational in housing.
