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.
Door handle is an ambiguous term, and includes door latches, bars, and knobs. Depending on the geographical location and its place in time, they vary in design, form and materials. The only constant is its function: an attachment used to open or close a door. The earliest doors extant are approximately 5000 years old. Door handles, as devices to manipulate a gateway, became a necessity shortly after the invention of the pivoting mechanism. To most, pivots are simply known as hinges, however, there are nearly as many hinge designs and configurations as there are handles. 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. Over time, large crossbars used to secure a door were supplanted by sliding bars, operated by a handle secured to the bar and projecting through a slot in the door, or as a pivoting bar - often called a latch - that could be dropped into a matching slot on the door jamb. In Colonial America, the operating mechanism for a small pivoting bar was a latch string threaded through a hole in the door near the handle. There are - probably apocryphal - accounts and references implying that this mechanism was a workaround for heavy taxes and a crown edict mandating the colonists could only use door latches or locks imported from England. About the middle of the 18th century, handles and locks were integrated into a single unit, the earliest known examples being levers that both operated the latch and served as a pull to open the door.
