Door Handles. Saturday , September 29th , 2018 - 18:43:12 PM
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.

The Kitchen is the one room in the house that presents the door handle manufacturer and supplier with a range of problems peculiar to that room and which are worth considering. The door handles require a number of design factors to be considered dependent on their position and usage. The first problem with a kitchen is that because it deals with food it is susceptible to the transmission of germs throughout the kitchen. Food is invariably transported and prepared by hand and this is then transmitted to other surfaces when cupboards are opened and closed. The fridge and freezer are the major culprits because these are the most commonly used appliances but the other cupboards are also a prime contenders. The use of door handles to open the cupboard doors are the prime region of contact where and whilst some materials are better than others for retaining germs, all of the handles do it to some degree. Therefore it is worth using a door handle that is easily cleaned on a regular basis so that any germs are disinfected quickly and precisely.
