A fold door refers to a type of door that is designed to fold in a specific manner for operation. It is characterized by a unique folding mechanism that allows the door to be partially or completely folded in a concertina-like fashion, creating a compact and space-saving solution.
The fold door typically consists of a series of hinged panels or sections, with each section attached to the next through a set of hinges or pivots. These sections can be made of various materials, including wood, glass, or aluminum, depending on the desired aesthetic and functional requirements.
The folding mechanism allows the door to smoothly fold and unfold, providing a versatile opening and closing system. When closed, the fold door forms a solid barrier, providing privacy, noise reduction, and insulation from the external environment. When open, it can be neatly folded to one side or both sides, maximizing the available space and creating a wide opening for easy access, especially in areas with limited space, such as closets, small rooms, or areas where a conventional swinging door may not be practical.
Fold doors are commonly used in residential, commercial, and industrial settings, offering functionality, flexibility, and aesthetic appeal. Their design versatility allows for customization in terms of size, style, and material, making them suitable for various architectural designs and interior décors.
The term "fold door" is a combination of two words: "fold" and "door".
The word "fold" comes from the Old English word "fealdan", which means "to bend, to turn, or to twist". It is related to the Middle Dutch word "vouwen" and the Old Norse word "falda", both of which have similar meanings. The word "fold" evolved to refer to the action of bending or turning something, such as folding a piece of paper.
The word "door" originates from the Middle English word "dore", which comes from the Old English "dur". It can be traced back to the Proto-Germanic word "*durz", meaning "door" or "gate".
When combined, "fold door" refers to a type of door that can be folded or bent.
