Abstract
A new and improved quiet hinge mechanism assembly comprises first and second hinge plates, and first and second connect plates. A pin shaft passes through the first and second connect plates, and a bushing and gasket are mounted upon the pin shaft such that the first connect plate does not engage the pin shaft, and the first and second connect plates do not engage each other. In addition, the bushing and the gasket are fabricated from a suitable, self-lubricating material, such as, for example, polyoxymethylene (POM), thereby rendering the new and improved hinge mechanism assembly quiet.
Claims15
A quiet hinge mechanism assembly, comprising:
- a first hinge plate having a first connect plate fixedly connected thereto, wherein said first connect plate has a first through-bore defined therein;
- a second hinge plate having a second connect plate fixedly connected thereto, wherein said second connect plate has a second through-bore defined therein;
- a pin shaft extending through said first and second through-bores of said first and second connect plates such that said first hinge plate can freely pivot/rotate around said pin shaft with respect to said second hinge plate;
- a bushing mounted upon said pin shaft, interposed between said pin shaft and said first connect plate, and separate and independent from said first connect plate such that said first connect plate can freely pivot/rotate around said bushing, and a gasket, separate and independent from said first connect plate, separate and independent from said bushing, mounted upon said pin shaft, and interposed between said first and second connect plates such that said hinge mechanism assembly comprises a connection, defined between said first and second connect plates, which comprises a serial array of a first head portion of said pin shaft, said bushing, said first connect plate, said gasket, said second connect plate, and a second head portion of said pin shaft;
- and
- wherein said bushing and said gasket are fabricated from polyoxymethylene (POM) such that when said first hinge plate pivots/rotates with respect to said second hinge plate, said hinge mechanism assembly is quiet.
