Virginie. Door Handles. November 22nd , 2017.
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.
The fridge and freezer are the major culprits because these are the most commonly used appliances but the other cupboards are also a prime contenders. The use of door handles to open the cupboard doors are the prime region of contact where and whilst some materials are better than others for retaining germs, all of the handles do it to some degree. Therefore it is worth using a door handle that is easily cleaned on a regular basis so that any germs are disinfected quickly and precisely.
As door handles easily catch germs and bacteria because of the variety of individual hands that touch them in the course of a day, it is important to consider the materials used. It is believed that certain materials like brass, copper and silver discourage the growth of bacteria and germs through some kind of electro-chemical effect; while other materials like aluminum, stainless steel, glass and porcelain do not have the same action. However, this belief has remained just that... a belief: and studies have not been extensive enough to confirm or disprove this possible effect, except in the case of silver. Hospitals in particular are experimenting with handle materials as they continue their fight against infectious disease within their wards.

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.
