Pivot hinges are a type of hardware used on pivot doors, enabling them to rotate around a central axis rather than swinging on traditional hinges. Unlike butt hinges which are attached to both the door and the frame, pivot hinges typically involve a system of top and bottom pivots, often mortised into the door itself. This allows for heavier doors and a more modern, sleek aesthetic.
How Pivot Hinges Work
The core functionality of a pivot hinge centers around a pivot system, usually consisting of:
- Top Pivot: Often mortised into the top of the door.
- Bottom Pivot: Similarly, mortised into the bottom of the door, providing counterbalance and support.
- Floor-mounted Socket (sometimes): In some designs, a floor-mounted socket is utilized to further stabilize the door. This creates a central point of rotation for smooth, effortless operation.
This system contrasts sharply with the typical butt hinge, which utilizes two leaves attached to both the door and the door frame for a traditional swinging motion.
Advantages of Pivot Hinges
Pivot hinges offer several key advantages:
- Support for Heavy Doors: They excel at supporting heavy, full-size doors due to the distributed weight support from the top and bottom pivots.
- Smooth Operation: The central pivot point facilitates a seamless, effortless opening and closing experience.
- Modern Aesthetics: They contribute to a cleaner, more modern look, often preferred in contemporary architectural designs.
- Versatility: Available in various styles, including offset pivots for doors that don’t need to fully align with the frame.
Types of Pivot Hinges
Several types of pivot hinges exist, catering to different needs and door weights. These might include:
- Standard Pivot Hinges: Designed for typical door weights.
- Heavy-Duty Pivot Hinges: Suitable for heavier doors and high-traffic areas.
- Offset Pivot Hinges: Allow for doors that don't need to perfectly align with the frame.
Choosing the correct pivot hinge is crucial; factors like door weight, material, and desired functionality are essential considerations.
