Butt hinges are a common type of hinge that provide a limited angle of rotation between two objects.
How Butt Hinges Work
Butt hinges function like most other hinges, by connecting two objects and allowing them to pivot. Here's a breakdown of their key components and how they operate:
- Leaves: Butt hinges consist of two flat metal pieces called leaves. One leaf is attached to a fixed object (like a door frame), and the other leaf is attached to the moving object (like a door).
- Knuckle: The leaves are connected by a central section known as the knuckle. This knuckle is made up of interlocking cylindrical parts.
- Pin: A pin runs through the knuckle, allowing the two leaves to pivot smoothly.
Key Features of Butt Hinges
- Limited Rotation: Butt hinges are designed to offer a limited range of motion, typically around 270 degrees.
- Simple Design: They have a basic construction, making them cost-effective and easy to install.
- Wide Variety: They come in various sizes, materials, and finishes to suit different applications.
Common Applications
Butt hinges are commonly used in a wide range of applications, including:
- Doors (both interior and exterior)
- Cabinet doors
- Boxes
- Furniture
- Trunks
Example Scenario
Imagine you are installing a new door. You would attach one leaf of a butt hinge to the door frame, and the other leaf to the door itself. The knuckle and pin allow the door to swing open and closed smoothly.
