When you consider that some 120 million doorways exist in the United States alone and another two million are installed each year you can only imagine the vast number of door knobs. Going back in history doors were initially made from textiles and animal hides. However during the ancient Mesopotamia and Egyptian era wooden doors were developed. Soon materials for making doors expanded to include stone glass metal and even paper.
The simplest handle is a pull - or push - projection on the side opposite the hinge. The placement of the handle is generally where it will provide an optimal mechanical advantage; most doors operating as second class levers. Doors with centre pulls or rings or a pivot point in a location other than one edge of the door use first or third class lever principles. Depictions of door handles in paintings dating to the first century CE are centrally placed hinged rings. The modern door knocker is a vestige of this style of primitive door handle. Doors were typically secured by bars and brackets to prevent them from being opened by either intent or accident.
These handles have a very long back plate around 180mm from end to end with the door emerging from the plate for about 47mm. The handle is gently curved with a slight upward lift at the end to give extra comfort to the user. Made in rose brass with brushed nickel or PVD brass or a bright coffee-coloured metal the Monet set of door handles comes with fixing screws and a 7.9mm spindle which can simply be pushed through the door. For users who want extra security it is possible to buy the Monet handles with a lock in the base of the plate. This lock can then be attached to the 3-lever mortice lock which is also available in this range and will provide security when used on the outside door of a home.
We have also seen door handles made from many different materials although most people think of some kind of metal. However handles have also been made from ceramic wood glass plastic etc. One of the oldest materials that are still among the more popular options is brass. For one thing brass looks gorgeous but it is also rust resistant. Todays brass door handle is somewhat different from those made in earlier times due to finishes. For instance for a more modern appearance many people choose brushed or satin brass.
