Door Handles. Wednesday , November 29th , 2017 - 05:17:20 AM
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.
Door handles are considered as one of the essential parts of any home or office. On one hand, they have practical uses; On the other hand, they add a lot to the overall interiors of home and office creating a great look and feel. Be it kitchen, bedroom, bathroom, living or dining area, nothing looks perfect without attractive handles and knobs. Since the use of door hardware have become a fashion statement, they are being widely used to add glitz and glamour to the over-all look of your home or office.
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.
