E05D HINGES OR SUSPENSION DEVICES FOR DOORS, WINDOWS OR WINGS (pivotal connections in general F16C11/00)
Description
E05D encompasses hinge systems and suspension mechanisms that enable the pivoting, rotating, or hanging movement of doors, windows, and similar hinged panels. This classification includes traditional pin hinges, ball-bearing hinges, pivot hinges, concealed hinges, and specialized suspension devices for both horizontal and vertical applications. The subclass covers the mechanical design of hinge components, fastening methods, and structural arrangements that facilitate smooth operation and load-bearing capability in building entrances, fenestration, and interior partition systems. Related classifications such as E05B (locks and latching mechanisms) and E05C (door closers and door holders) address complementary fitting functions rather than the primary rotational support provided by hinges.
