Door Handles. Wednesday , September 12th , 2018 - 13:05:05 PM
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. 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.
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 Kitchen is the one room in the house that presents the door handle manufacturer and supplier with a range of problems peculiar to that room and which are worth considering. The door handles require a number of design factors to be considered dependent on their position and usage. The first problem with a kitchen is that because it deals with food it is susceptible to the transmission of germs throughout the kitchen. Food is invariably transported and prepared by hand and this is then transmitted to other surfaces when cupboards are opened and closed. 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.
