Self-Closing Hinge
This hinge is smaller and much sleeker in comparison to previously developed self-closing hinges. The hinge incorporates an interchangeable spring system to easily allow for adjustments to closing force post installation. The hinge utilizes a lift off feature allowing the user to remove the door without disassembling the hinge or detaching the connections to the doorjamb. The hinge has the ability to accommodate both right to left-opening doors. The hinge lifts doors slightly while opening to prevent abrasion to the bottom seal in doors that have no step or transition from the outside floor to the inside floor.
Boise State University has developed a robust and adjustable self-closing hinge that incorporates multiple benefits into a small, compact, aesthetically pleasing design. This invention utilizes a spring assist function placed around the closing cams, allowing it to be smaller and more adjustable post installation. The design allows the hinge to be ambidextrous and therefore can be placed on right or left handed openings. The hinge also has a lift off feature enabling the user to quickly and easily remove the door without dismantling the product. All of these futures are accomplished in a sleek compact package.
