DIFF Subclass Not Allocatable
E06B

FIXED OR MOVABLE CLOSURES FOR OPENINGS IN BUILDINGS, VEHICLES, FENCES OR LIKE ENCLOSURES IN GENERAL, e.g. DOORS, WINDOWS, BLINDS, GATES (shades or blinds for greenhouses A01G9/22; curtains A47H; lids for car boots or bonnets B62D25/10; skylights E04B7/18; sunshades, awnings E04F10/00)

Introduced: September 1968

Description

E06B covers the design and construction of closures for openings in buildings, vehicles, fences, and comparable structures, including doors, windows, blinds, gates, and related hardware. This subclass encompasses both fixed installations (e.g., fixed windows, stationary panels) and movable closures (e.g., hinged doors, sliding windows, roller blinds, swing gates), as well as their structural components and operating mechanisms. The classification includes general closure systems and assemblies that do not fall under more specialized subclasses dedicated to specific closure types or technical features (such as emergency exits or specialized sealing systems). Adjacent subclasses (E06C, E06D) address more particular technical aspects like closures with special heating/cooling functions or specific movable door and window mechanisms.
