Double Action Spring Hinges 

When it comes to doors, particularly ones that need to swing open and closed in both directions, a special type of hinge is required: the Double Action Spring Hinges. These hinges are commonly used in places like restaurants, hospitals, and commercial buildings, where frequent door movement is necessary. If you’ve ever wondered how these doors work or whether double action spring hinges could be the right choice for your project, you’re in the right place. In this blog, we’ll explore what double action spring hinges are, their benefits, and how they function. 

What Are Double Action Spring Hinges? 

A Double Action Spring Hinge is a type of hinge that allows a door to swing in both directions. Unlike traditional hinges, which allow a door to open in just one direction, Double Action Spring hinges allow the door to swing open and closed on both sides. These hinges are designed with a built-in spring mechanism that helps the door return to a closed position automatically, even after being pushed open from either side. 

These hinges are typically used in applications where doors need to be able to swing both ways, such as in commercial kitchens, cafeterias, hospitals, or in buildings where heavy foot traffic is common. The spring mechanism within the hinge ensures that the door will always close after someone pushes it open, eliminating the need for manual effort to pull the door shut. 

Key Features of Double Action Spring Hinges: 

1.Bidirectional Movement: As mentioned, these hinges allow doors to swing open in both directions, making them highly versatile. 

2.Self-Closing: The built-in spring forces the door to close automatically after it’s been opened. 

3.Durability: Double action spring hinges are designed for high-traffic areas and can withstand heavy use without losing their functionality. 

4.Adjustability: Many double actions spring hinges allow you to adjust the tension of the spring, controlling how quickly or slowly the door closes. 

Where Are Double Action Spring Hinges Used? 

Double action spring hinges are ideal for applications where doors need to swing in both directions and return to a closed position without human intervention. Here are some common uses:

1.Restaurants and Cafeterias

In kitchens and dining areas where people are constantly moving back and forth, double action spring hinges provide a practical solution. Staff carrying trays or dishes can easily pass through the door in either direction without having to manually close it each time.

2.Hospitals and Healthcare Facilities

In hospitals, double action spring hinges are often used for doors that separate patient rooms, bathrooms, or medical offices. These doors need to open both ways for staff to move in and out quickly, especially when their hands may be full. The self-closing feature helps maintain privacy and reduces the risk of contamination.

3.Commercial Buildings

In high-traffic commercial spaces such as malls, office buildings, and factories, double action spring hinges allow for quick and easy access while reducing wear and tear on the doors. The automatic closing feature ensures that doors are always securely closed, improving safety and security.

4.Public Spaces

In public areas like libraries, schools, or airports, double action spring hinges are commonly used for doors that lead to restrooms or other important areas. They help improve convenience and prevent doors from staying open in busy spaces, keeping the areas secure. 

How Do Double Action Spring Hinges Work? 

Double action spring hinges function through a simple mechanism involving springs and pivot points. Here’s a breakdown of how these hinges work:

1.Pivot Mechanism

At the core of a double action spring hinge is a pivoting mechanism. The door is attached to the hinge on either side and can swing in both directions. The hinge is mounted in a way that allows the door to swing outward to one side, then reverse direction and swing outward again when pushed from the other side.

2.Spring Mechanism

Inside the hinge is a spring, which is the key to the self-closing function. When the door is pushed open, the spring inside the hinge stretches. When the door is released, the spring contracts, pulling the door back to its closed position. The tension of the spring can often be adjusted to control the speed of the door’s closure.

3.Dual Action

The hinge allows the door to return to its closed position regardless of which direction it is pushed. This is achieved by the dual-action mechanism that enables the hinge to function both ways. This feature makes the hinges ideal for spaces where traffic flows in both directions.

4.Tension Adjustment

Many double action spring hinges come with adjustable tension. This means you can fine-tune the spring tension, which influences how fast or slow the door closes. For example, if you want the door to close more quickly, you can tighten the spring, while loosening the spring will slow down the closing speed.

Installing Double Action Spring Hinges 

Installing double action spring hinges is relatively straightforward, but it’s important to follow the manufacturer’s guidelines to ensure proper function. Typically, you’ll need to: 

1.Position the Hinges: The hinges are mounted to the top and bottom of the door frame. 

2.Adjust the Tension: Set the desired tension level for the spring, based on how quickly or slowly you want the door to close. 

3.Test the Door: Once the hinges are installed, open and close the door a few times to ensure that it swings freely and closes correctly. 

For optimal performance, it’s essential to regularly maintain the hinges, especially in high-traffic environments. Lubricating the hinges and checking the tension can help prolong their lifespan. 

Conclusion 

Double Action Spring Hinges offer an efficient and practical solution for many types of doors in commercial, industrial, and public spaces. Their bidirectional functionality and self-closing features make them an excellent choice for high-traffic areas, providing convenience, security, and durability. Whether you’re outfitting a restaurant, a hospital, or a busy office building, these hinges can help improve door function and make your space more user-friendly.
