Door Handles. Monday , October 01st , 2018 - 15:29:31 PM
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.
Door handles are really an important part of every door. They are really the most vital part that can simply become lighter into the background instead of the fact that we use them daily. Almost every person uses these handles to push and pull the door when they come in or walk out of the room. These door handles are just like the autopilot and they help us a lot but we do not even give a look to these handles. Just imagine that how hard it would be to push or pull the heavy doors without the handles. These door equipments are really very efficient and carry an essential importance in every house.
To most Americans, the terms handle and knob are synonymous. In Europe, however, door levers constitute the vast majority of door handles. Because of their utility and accessibility, door levers are gaining popularity in the United States. They are far easier for an individual physically challenged by arthritis, disease or injury to operate than round door knobs. While exterior and large door handles will eventually be supplanted by automatic opening mechanisms, door handles will continue to necessary for smaller doors on interior doors, cabinetry and other furniture for centuries to come.
