Alacoque Door Handles September 08th, 2017 - 08:06:56
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.
While the Storm door handle could be described as an attempt to mix and match the two previous options, it really stands out on its own. The very long back plate is 185mm, over 50mm more than the length of the lever handle (which is 127mm). The handle itself is slightly curved, although not enough to be very noticeable, and is a single length of handle, rather like the Monet. It features the different colour metal on the palm pad, as exhibited by the Nimbus, which makes it an ideal match for a more modern house. The Storm door handle is also available with a lockable back plate which again matches a mortice lock in the same style.
Door handles have become like fashion statements at the top end of the market, as some variations come in intricate and ornate designs to add glitz and glamor to the over-all look of your home. While retaining its main functionality of opening and closing doors, variations in handle design often come in relation to particular needs and requirements such as: for nursery rooms, handles sometimes come in cheerful cartoon designs; for kitchen doors, some have fruit embellishments; for a girls room, pink handles are also available. These are fancy handles: but for permanent and lasting use, most homes use the more versatile materials such as brass and metal handles, which can withstand repeated use, and can adapt to most household interiors.
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.
