Bifold doors work by folding in panels, much like an accordion or concertina, to create a wide opening. These doors are made up of multiple leaves (or panels) that are hinged together, allowing them to fold back on themselves. When opened, the leaves stack neatly to one or both sides, maximizing the available space. When closed, they slide flat to create a solid wall.
Here's a breakdown of how they function:
- Hinged Panels: Each panel is connected to the next by hinges, allowing them to fold.
- Track System: Bifold doors use a track system, typically both at the top and bottom, to guide their movement.
- Rollers/Guides: The top track usually contains rollers attached to the top of the doors, while the bottom track may have guides to keep the doors aligned. These components allow the doors to slide smoothly along the track.
- Folding Action: When you push or pull the lead door, the other panels follow, folding in sequence.
- Stacking: The folded panels stack against one or both sides of the opening, creating a larger unobstructed space compared to traditional hinged or sliding doors.
- Locking Mechanism: Bifold doors usually have a locking mechanism to secure them when closed. This may include a multi-point locking system for enhanced security.
In essence, bifold doors combine the functionalities of traditional hinged doors and sliding doors, offering a flexible and space-saving solution for opening up rooms to the outdoors or connecting interior spaces. They are commonly used as patio doors, room dividers, and closet doors.
