Special Application Hinges

Butt hinges as mentioned in our previous post are by far the most popular choice for hanging internal doors, however there are a wide variety of hinges that have been developed with a specific purpose in mind. In this article we will look at some of these hinges and their application.

Parliament and Projection Hinges

Projection & Parliament Hinges

In some cases doors need to open to 180 degrees and although butt hinges are capable of doing this there are often obstacles preventing them from doing so, such as an architrave on the door frame or a reveal if the door is set back within a brick opening. Both parliament and projection hinges overcome these obstacles by having a protruding knuckle, which increases the throw of the door. The distance between the knuckle and hinge edge determines the degree the door will open. Although both styles of hinge provide the same function, parliament hinges have a shortened knuckle which can be more aesthetically pleasing, whilst projection hinges have a full length knuckle enabling them to offer a higher load bearing capacity.

Rising & Falling Butt Hinges

Rising & Falling Butt Hinges

Rising butt hinges are used when the door needs to rise slightly when it is opened, this may be due to it needing to clear a mat, rug or thick carpet for example. The approximate rise is around 6mm and as a result the top of the door near the hanging edge will need special preparation. The added feature of rising butt hinges is that they result in the door self closing due to gravity, which can be useful on toilet doors. Falling butt hinges work in the opposite way to rising butts as the door falls open under gravity. In this case special preparation needs to be made to the bottom of the door. These hinges are often used in cases where it is beneficial for the door to be open, again toilet cubicles are one such case as people can see which ones are vacant. Both of these types of hinge are handed (right or left) so it is necessary to state which hand is needed. If it is unclear as to what hand you require our technical team would be glad to assist you.

Spring Hinges

Single & Double Spring Hinges

Just as the name suggests these hinges incorporate a spring mechanism in the knuckle. The purpose of this is to close the door automatically after it has been opened. The tension of the spring can be adjusted to allow the speed of closing to be altered. These can often be used instead of a door closer offering a more aesthetically pleasing option for your fire doors, which must self-close. Our spring hinges are fire tested meeting BS EN 1634 and are suitable for one hour fire doors. They are also available in either polished or satin stainless steel finish. We also stock double spring hinges, often referred to as a ‘bommer’ hinge (a trade name from America), which are used when the door needs to open both ways, this is often the case on restaurant kitchen doors for example. These are available in a variety of sizes to suit various sizes and weights of doors.

Other Special Application Hinges

Security, Cabinet, Counterflap & Stormproof hinges

Security, Cabinet, Counterflap & Stormproof hinges

There are a number of other hinges which are for a specific purpose or special application. Security butt hinges incorporate hinge studs (hinge bolts) on the hinge which engage in a matching hole on the opposite leaf, meaning that when the door is in the closed position it cannot be removed even if the hinge pin is removed. This is an especially important aspect to look at on outward opening external doors.  Cabinet hinges are small butt hinges designed for use on cabinet or cupboard doors and are available in two different sizes and a variety of finishes. Counterflap hinges are a double pivoted hinge which allow flush fitting and are therefore perfect for use on bar counters as they allow for part of the counter to be opened for staff to move behind the bar but they do  not obscure the bar surface when glass collecting or cleaning as a normal butt hinge would. Stormproof hinges are specifically used on casement style windows and are cranked to allow for the rebate of the casement. These are available in a yellow passivated, brass self colour or zinc plated finish.

In addition to all of the hinges mentioned above we are also able to source a huge variety of other hinges and sell many from our shop in Ascot. These include SOSS hinges, Tee hinges, Conductor hinges, Tectus hinges, Lift-off hinges and many many more.
