Emmeline. Door Handles. September 22nd , 2017.
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.
Besides security, it is important to consider the functionality of the door furniture handle. If the door is made of hardwood, it should have a handle mechanism that makes it easy to open and close the door. Furthermore, handles in common passage doors need to be durable to handle the continuous handling. You can then use the less durable but more beautiful handles for the inner doors that may not require a lot of opening and closing. A major concern with door knobs especially for public doors is the hygiene. People including medical practitioners have argued that handles do spread contagious diseases. By using materials like brass, copper and silver, you reduce the infection rate since these metals are poisonous to germs.
If you want to maintain the polish of these handles, then the best possible and safest method is to use the natural and harmless products available in your kitchen. One possible method is to combine flour, vinegar and salt to make a paste then apply it on your handles. Similarly, you can also use pure lemon juice as a substitute of vinegar. If you are using ammonia, then slightly dip a piece of clean cloth in it and rub it on your handles. If you are using supermarket polish, then use the same procedure as with ammonia to rub it. This polish has the ability of removing grease, grime and dirt.
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.
While different types of door handles are designed with unique components, the average handle has basic components. For instance, in addition to the knob top, which is the large knob that you would actually grab hold of to turn, handles are made with a spindle, shank, and knob rose. The knob rose is a round washer or plate used to form a socket. This piece is adapted so it can be attached to the actual door. Then, there is that spindle, which is the thin piece to which the handle attaches. The shank is the stem that projects from the door handle. Within the shank is a hole in which the spindle would be placed. For functionality, the door handle would be attached so the metal shaft can turn the latch to open the door.
