Einflügelig

Einflügelig is a German term that translates to "single-winged." It is commonly used in engineering and architecture to describe components that have only one moving part or section, particularly in relation to doors, gates, windows, or adjustable surfaces. For example, an einflügelig door is a standard door that swings open on a single hinge. This contrasts with zweiflügelig, meaning "double-winged," which describes doors or gates with two symmetrical sections that meet in the middle.

The term is also applicable in other contexts. In aviation, while less common in everyday usage, it could theoretically refer to a wing configuration. However, its primary and most frequent application is in describing the structure of openings and closures in buildings and other constructions. The simplicity of an einflügelig design often implies a straightforward mechanism and a single point of pivot. This can affect factors such as the space required for operation, the complexity of the locking mechanism, and the overall aesthetic. When specifying building components, einflügelig clearly communicates the design's single-panel nature.
