Components of Piano Hinges
Piano hinges consist of two leaf plates, connected by a pin that runs the length of the hinge. The leaf plates are the long, flat pieces that are attached to the surfaces being joined. The pin is the cylindrical rod that connects the leaf plates and allows for rotational movement. The knuckles are the cylindrical portions of the hinge that surround the pin and connect the leaf plates. Finally, the flange is the portion of the hinge that is attached to the surface, providing support and stability.
Variations of Piano Hinges
There are several variations of piano hinges, each with unique features and applications. Continuous hinges are the most common type of piano hinge, consisting of a single long piece of metal that runs the length of the joint. Strap hinges are similar to continuous hinges, but are wider and have a more decorative appearance. Concealed hinges are designed to be hidden from view, often used in cabinetry and furniture applications. Specialty hinges include take-apart hinges, which can be easily disassembled, and offset hinges, which allow for the hinge to be offset from the surface it is attached to.
Materials Used for Piano Hinges
Piano hinges are commonly made from stainless steel, brass, aluminum, and plastic. Stainless steel is the most popular material due to its high strength and durability, as well as its resistance to corrosion and rust. Brass is a popular choice for decorative applications due to its attractive appearance, while aluminum is commonly used in lightweight applications such as aerospace and automotive industries. Plastic piano hinges are used for low-stress applications and offer a cost-effective alternative to metal hinges.
Considerations for Piano Hinges
While piano hinges offer many benefits, there are also some limitations to consider. The weight capacity of piano hinges can be a concern, as they are not designed to handle heavy loads. They are also susceptible to rust and corrosion if not made from the proper material, and their flexibility is limited compared to other types of hinges.
Benefits of Piano Hinges
Despite their limitations, piano hinges offer many benefits. They are easy to install and offer a high level of strength and durability. Their aesthetic appeal makes them popular in furniture and decorative applications, and their versatility and flexibility make them useful in a wide variety of industries and applications.
