Hinges are a type of mechanical bearing that connect two solid objects, typically allowing only a limited angle of rotation between them. As pivotal hardware components, hinges facilitate the opening and closing of doors, lids, cabinets, and other hinged objects by providing a smooth pivot point. Their main function lies in providing support while enabling movement, ensuring that the connected parts can swing or move back and forth with ease and reliability. Characteristics of hinges include their load-bearing capacity, durability, material composition, size, and the degree of movement they allow, which can range from simple back-and-forth motions to more complex multi-axial rotations.
The primary uses of hinges are found in residential and commercial structures, on entry and interior doors, windows, cabinets, and various types of furniture. They also find utility in industrial settings, where they're used on heavy-duty gates, machinery access points, and storage containers. Hinges come in many forms, including butt hinges, continuous hinges, piano hinges, and specialized types like self-closing or concealed cabinet hinges, each tailored to specific needs and applications. Several recognized manufacturers of hinges include Stanley Black & Decker, Hettich, Blum, and Sugatsune, among others.
