SS304 Single Action Spring Hinge-DDSS033

Single-action spring hinges are designed for doors that automatically close in one direction. 

Detailed specifications follow:

Core Functionality

Automatic Closing: The primary function is to close the door automatically after opening. This is achieved through the spring mechanism within the hinge.

Unidirectional Operation: They operate in one direction only. The door swings open, and spring tension pulls it shut.

Key Components and Mechanical Principles

Spring Mechanism: The hinge incorporates a helical spring. When the door is opened, the spring coils and stores energy. Upon release, this stored energy propels the door shut.

Adjustable Tension: Many single-action spring hinges feature adjustable tension. This allows control over the force with which the door closes.

Hinge Leaves: Like standard hinges, they comprise two leaves (plates) attached to the door and door frame respectively. These leaves are connected via the spring mechanism.

Applications

Screens: Commonly used on screens to ensure they remain closed, preventing insect entry.

Lightweight Interior Doors: Suitable for lightweight interior doors requiring automatic closure.

Gates: Suitable for lightweight garden or small boundary gates.

Advantages

Convenience: Eliminates the need for manual closing.

Security: Prevents accidental opening, enhancing safety.

Energy efficiency: Ensures proper closure, minimising draughts.

Disadvantages

Weight limitation: Not suitable for heavy doors.

Noise: May produce a noticeable “clunk” upon closing.

Wear: Spring mechanisms may deteriorate over time, requiring replacement.

Installation

Preparation: Mark hinge positions on door and frame.

Mortise (if required): Chisel recesses (mortises) for hinge blades to sit flush with surfaces.

Attachment: Secure hinge blades to door and frame using screws.

Tension Adjustment: Modify spring tension using the adjustment mechanism (typically a pin or screw) as required.

Considerations

Door Weight: Ensure the hinge's weight rating matches the door's mass.

Usage Frequency: High-traffic doors may require sturdier hinges.

Desired Closing Speed: Adjust tension to achieve the preferred closing velocity.
