A hinge door works by rotating around a fixed axis provided by the hinge, allowing the door to swing open and closed relative to the door frame.
Here's a breakdown of how it works:
-
The Hinge: The hinge is the crucial component. A typical door hinge consists of two metal leaves (plates) connected by a pin. Each leaf is attached to either the door or the door frame.
-
Attachment: One leaf of the hinge is securely fastened to the door, while the other leaf is securely fastened to the door frame (also known as the jamb). This creates a connection between the door and the frame.
-
The Axis of Rotation: The pin that connects the two leaves of the hinge creates a fixed axis. This axis is what the door rotates around.
-
Swinging Motion: When force is applied to the door (pushing or pulling), the door swings around the axis created by the hinge pin. The leaves of the hinge rotate relative to each other, allowing the door to move between open and closed positions.
-
Functionality: The design of the hinge ensures that the door swings smoothly and predictably. The number of hinges used on a door depends on the door's size and weight, with heavier doors requiring more hinges for stability and proper function.
In simple terms, the hinge acts as a pivoting joint, enabling the door to swing back and forth. The fixed axis of rotation provided by the hinge is what allows the door to move relative to the frame.
