Continuous hinges are a crucial component in doors, cabinets, lids, and enclosures, providing stability and strength. In this article, we will explore the world of continuous hinges, their history, types, materials used, and the advantages they offer.
Chapter One – What is a Continuous Hinge?
A continuous hinge is a long single unit hinge that runs the entire length of a door, cabinet, lid, or enclosure. Made from materials such as nickel, brass, aluminum, steel, and stainless steel, continuous hinges are cut to fit the size of the opening. Originally known as piano hinges, they were first used to hold grand piano lids. As their use expanded, they became popularly known as continuous hinges.
Chapter Two – The Evolution of Piano Hinges
The piano hinge was invented to support the cover or lid that protects the major components of a piano. Craftsmen and designers were challenged to create a hinge that could span the full length of the lid without interfering with the resonance and sound of the instrument. The initial piano hinges were meticulously handcrafted, but as their use grew, manufacturers developed faster and more economical production methods. Today, continuous hinges are manufactured using advanced processes, including feeding steel through machines to create the knuckles and assembly.
Chapter Three – The Versatility of Continuous Hinges
Continuous hinges have evolved into various types to serve diverse applications. These include carbon-Kevlar hinges, friction hinges, geared hinges, interleaf hinges, pin and barrel hinges, plastic hinges, slip joint lift-off hinges, slip-on hinges, and tight clearance hinges. Each type has its unique design and features tailored to specific needs.
Chapter Four – Benefits and Uses of Continuous Hinges
Continuous hinges offer several advantages over traditional hinges, including their ability to support heavy loads and withstand extensive use. They are commonly used in piano lids, shed and barn doors, fire doors, prison doors, marine environments, and desk tops. Continuous hinges ensure stability, durability, and a secure seal, making them ideal for various applications.
Chapter Five – Materials Used in Continuous Hinges
Continuous hinges are typically made from metals such as aluminum, stainless steel, and steel. These materials provide strength, resilience, and corrosion resistance. However, technological advancements have also introduced plastic and carbon fiber materials, offering lighter alternatives without compromising durability.
Chapter Six – Advantages of Continuous Hinges
Continuous hinges offer several advantages, including maintaining proper position, distributing stress evenly, providing a tight seal, enabling easy customization, and offering exceptional durability. Their continuous design ensures smooth operation and prevents sagging or wavering over time.
Continuous hinges have come a long way since their humble origins as piano hinges. With their strength, endurance, and versatility, they have found applications in various industries. Whether for residential, commercial, or industrial use, continuous hinges provide stability, security, and durability that traditional hinges cannot match. Consider them for your next project and experience the benefits they bring.
