Lever operated door handles are very popular in European homes as they are easier to use. This makes them suitable for elderly people as this design of these handles does not require a tight grip; unlike the door knob which may slip from the users hand. The door knob is more commonly used in the United States because of its practicality and dual functions: it functions as a door latching mechanism and a lock at the same time. However U.S. commercial and business establishments have woken up to the practicality of using the lever style of door handles. Aside from easy operation they are less likely to jam. Further the lever operated handles are more robust and can withstand constant use.
Doors throughout history have also changed regarding functionality. For instance we still find doors of all types those that roll slide swing and fold. Of course for doors to function hardware is required to include door handles. Just as with doors handles have a long history although these were first manufactured during the mid-19th century in America. The first handle was shaped like an egg and today they are still found in many homes especially older homes. Interestingly because of the way this type of door handle is grasped it has proved to be the easiest to open.
Brass door handles are available in variety of types like reproduction period and antique period brass. Many other types of them are also available in the market and all of them are capable of greatly enhancing the looks of your house. However the reproduction and antique period brass are like a premium type of brass as they are more durable and last longer than other types. This type of door hardware usually doesnt wear off easily and even when its finish fades away it will still give an antique look and will match the decoration of your house.
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.
