Calandre Door Handles August 23rd, 2018 - 04:12:22
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.
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.
Whilst you may have spent hours helping your grandparents polish the fireside companion set when it comes to your door handles the best way to keep your polished brass door furniture looking shiny is with plain and simple warm soapy water and a soft cloth. The polished brass ranges we supply have all been treated with a special lacquer and the use of metal polishes or other abrasive cleaners will damage this and cause it to wear away far quicker than it would under normal use. Eventually after a good few years of use this lacquer may well breakdown at which point you should remove the door handle or pull and treat it with an acetone thinner applied with a soft brush. Dry well with a soft cloth and then polish up with a metal polish. Regular polishing thereafter will keep them looking great.
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.
