What is the purpose of a Spring Hinge

Updated: Nov 3, 2020


What is the purpose of a self closing spring hinge? A spring hinge is used to self close a door or gate. There are single spring and there are double sprung hinge types.



Spring hinges are self-closing hinges. A spring mechanism in the barrel allows the hinges to automatically close a door which enables these hinges to serve as an alternative to overhead mounted door closer. The closing power of the hinges can be adjusted whilst still on the door or gate.

A spring hinge, also known as spring loaded hinges, self-closing hinges, and door closing hinges, are hinges fitted with a spring, automatically closing the door from an opened position.



Are spring hinges adjustable.


The spring tension is adjustable to allow the spring to close the hinge slowly without slamming shut the gate or door.


Double action spring hinges allow a door to open 180 degrees in either direction. The spring action returns door to center closed position. These hinges are great for any door you want to walk through in both directions and have the door come back to center automatically.



How do spring hinges work


A spring-loaded hinge works to ensure that a door automatically closes without you having to push or pull. It works by using the tension of the spring to move the door, and how much tension is needed depends on the weight of the door and the desired speed of the closure.



Removing a spring loaded hinge


A spring-loaded hinge should only be removed when the door is closed to avoid it slamming. Using a hex wrench, open the spring so you can see the tension pin. Then, remove the pin using pliers. You can then remove the hex wrench and allow the spring to naturally unwind.



The Bonco Hinge


The Bonco Spring hinge is a heavy duty sprung hinge suitable for most commercial and residential gates and doors. Adjustable for the weight of the gate up to 60 kg. Adjustment is usually achieved by the turn of a hex key inserted at the top of the hinge itself.


The hinge is 102 x 102 and 3 mm thick stainless steel. Adjustment by hex wrench or Allen key. The terms "Allen wrench" and "Allen key" are derived from the Allen brand name and refer to the generic product category "hex keys". W.G. Allen filed the first related patent in 1909 for its recessed hex-driven safety screws, a safety improvement over fasteners which protruded from machinery.

Adjustment


If the self-closing door isn’t closing hard enough to latch properly, you can adjust the spring tension with the hex key - one click at a time! The trick is... one click at a time! If you over tension the spring, the door will slam shut.


When you adjust one click at a time and check closing speed you will find the correct adjustment needed. If the door slams shut, you can adjust the spring tension with a hex wrench, and pliers.


When you unpack your spring hinges DO NOT ADJUST tension until you fit the hinges on the gate or door.



Double Sprung and Single Sprung Justor Hinge


Justor’s wide range of products offer solutions for single action as well as double action doors (swing doors).



The Justor spring hinge system is founded on a set of laminated blades that work by torsion. It’s this torsion action that underpins the high performance of the Justor spring hinge range. Unlike a coil spring, torsion blades don’t stretch over time or loose their ability to bounce back when under strain.


Due to revolutionary design, the double action spring hinges from Justor of Spain mount directly to a flat surface. No need to build out the wall or the jamb to cater for the knuckles of the hinge. Screw straight onto the wall. Simple, clean and easy.
