The present invention provides a self-closing hinge to provide automatic closing of a hinged member in a slow fashion. The invention includes a generally cylindrical outer casing or housing that partially encloses a rotatable shaft that may be secured to a hinged member to effect the rotation thereof. The shaft is disposed within a recess in a cylindrical coupler that is engaged by the shaft during rotation in a first direction - generally an "open" rotational direction - and that engages the shaft to rotate it in a second direction - generally a "closed" rotational direction. The coupler is secured to a torsional spring that acts against the open rotation of the shaft, forcing the coupler to rotate in a closed direction. A rotatable inner casing, may be disposed within the outer casing in close proximity thereto, such that a high viscosity fluid may be disposed therebetween. |
