Roto hinges are specialized pivoting hinges used in various applications where a rotating or folding action is needed. They offer a unique solution compared to traditional hinges, providing 360-degree rotation or a controlled pivot within a specific arc.
Construction and Materials
Roto hinges are typically made of durable materials designed for specific applications. One common type is constructed from maple wood with zinc-plated steel rivets, making them suitable for woodworking projects. Other types may utilize stainless steel or other metals for greater strength and durability, as seen in examples from various manufacturers like Roto North America and Captain Cold. The choice of material dictates the hinge's strength, resistance to corrosion, and overall suitability for the intended use.
Applications and Uses
Roto hinges find applications in a wide range of projects and products. Common uses include:
- Furniture: Folding chairs, tables, and other furniture pieces often utilize roto hinges to allow for easy folding and storage.
- Cabinetry and Boxes: They can be used on box lids and cabinet doors where a pivoting action is desired.
- Wooden Toys: The smooth rotating action makes them suitable for children's toys.
- Louvers: Roto hinges allow for the controlled adjustment of louvers for ventilation or light control.
- Doors: While less common for standard door hinges, specialized roto hinges are available for certain door applications (e.g., Roto North America offers hinges for swing doors).
Installation
Installation typically involves drilling a precisely sized hole and inserting the hinge. For example, Lee Valley Tools recommends drilling a 7/16" deep hole for their 3/8" size roto hinge. A small amount of glue may be used to secure the hinge in place.
