Another variety is the Pannus, which features a very round and attractive door lever shape. This is round, rather similar to the shape of a water fountain spout, and is designed to allow the user the maximum push possible. The handle itself is very closely connected to the fixing point of the door, and the palm pad is covered by a layer of shining metal which is intended to provide more comfort to the user. This style of door handles also has a second option in the Pannus (new), which is again, a door lever very close to the spindle. In this case, the lever is not curved in the same elegant style, but instead starts at a very narrow point before inflating to a larger size and then narrowing again to a point at the end. This provides a very soft and luxurious feel to the hole handle.
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.
