A center pivot hinge, often just called a pivot hinge, functions by allowing a door to swing from a single point located at the top and bottom of the door.
Understanding Pivot Hinge Mechanics
Pivot hinges differ from standard door hinges which are mounted on the side of the door. Instead, these hinges are:
- Attached to the top and bottom of the door.
- Fixed to the head of the frame and the floor, providing the rotation point.
This setup enables the door to swing or pivot in either direction around this central axis, unlike traditional hinges that restrict the direction of movement.
Key Components of a Pivot Hinge System
A typical pivot hinge system involves:
- Top Pivot: This component is installed into the door's top edge and the door frame's head.
- Bottom Pivot: This component is installed into the door's bottom edge and the floor.
- Pin: A sturdy pin connects the top and bottom pivots allowing the door to rotate.
Practical Applications
Pivot hinges are used in various applications and situations where their unique functionality proves beneficial:
- Oversized Doors: They are well-suited for large or heavy doors where typical side-mounted hinges might struggle to support the weight.
- Modern Designs: They contribute to a clean, modern aesthetic, as the hinges are mostly concealed, emphasizing the door's design.
- Double-Action Movement: The ability to swing both ways makes them useful in high-traffic areas, like a kitchen and dining room.
How a Pivot Hinge Differs from Traditional Hinges
The table below highlights key differences:
| Feature | Pivot Hinge | Traditional Hinge |
|---|---|---|
| Mounting Point | Top and bottom of the door | Side of the door |
| Movement | Pivots from a central point; swings both ways | Swings in a single direction |
| Visibility | Mostly concealed | Usually visible |
| Best Use | Large doors; modern designs; high traffic | Standard residential and commercial door applications |
In conclusion, a pivot hinge’s design allows doors to rotate on a central axis, offering functionality and aesthetic advantages over traditional hinges.
