Hinges are simple mechanical devices that allow two objects to pivot around a central point. They are commonly found on doors, gates, and cabinets, enabling them to open and close smoothly. A hinge typically consists of two plates, called leaves, that are connected by a pin. This design allows one leaf to remain fixed while the other moves, making it easy to access what’s inside. There are various types of hinges, including butterfly hinges, piano hinges, and concealed hinges. Each type serves a specific purpose and is chosen based on the needs of the object it supports. For example, piano hinges are long and provide stability for larger doors, while concealed hinges are hidden from view for a cleaner look.
