Swivel Chair
A swivel, swivelling, spinny, or revolving chair is a chair with a single central leg that allows the seat to rotate 360 degrees to the left or right. A concept of a rotating chair with swivel castors was illustrated by the Nuremberg noble Martin Löffelholz von Kolberg in his 1505 technological illuminated manuscript, the so-called Codex Löffelholz, on folio 10r. It is purported that Thomas Jefferson drafted the United States Declaration of Independence in 1776 while sitting on a swivel chair of his own design. Types and examples Swivel chairs may have wheels on the base allowing the user to move the chair around their work area without getting up. This type is common in modern offices and are often also referred to as office chairs. Office swivel chairs, like computer chairs, usually incorporate a gas lift to adjust the height of the seat, but not usually large (e.g. recliner) swiveling armchairs. A draughtsman's chair is a swivel chair without wheels that is usually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desk Chair
An office chair, or desk chair, is a type of chair that is designed for use at a desk in an office. It is usually a swivel chair, with a set of wheels for mobility and adjustable height. Modern office chairs typically use a single, distinctive load bearing leg (often called a gas spring, gas lift), which is positioned underneath the chair seat. Near the floor this leg spreads out into several smaller feet, which are often wheeled and called casters. Office chairs were developed around the mid-19th century as more workers spent their shifts sitting at a desk, leading to the adoption of several features not found on other chairs. History The concept of a swiveling chair with castors was illustrated by the Nuremberg patrician Martin Löffelholz von Kolberg in his 1505 technological illuminated manuscript, the so-called Codex Löffelholz, on folio 10r. One of the earliest known innovators to have created the modern office chair was naturalist Charles Darwin, who put wheels on the cha ...

Bucket Seat
A bucket seat is a car seat contoured to hold one person, distinct from a flat bench seat designed to fit multiple people. In its simplest form, it contours somewhat to the human body, but may have a deep seat and exaggerated sides that partially enclose and support the body in high-performance automobiles. Before World War II, the term ''Kübelsitzwagen'' (meaning ''bucket-seat car'') became popular in Germany, for light open-topped, cross-country and military vehicles without doors, because these were typically equipped with bucket seats, to help keep occupants on board, in an era before the adoption of seat belts. This body style had first been developed by in 1923. They are typically standard in front of fast cars to keep drivers and other passengers in place when turning at speed. Rear "bucket seats" are typically hybrids of bench and true bucket seats, being contoured like the latter but fixed in place, even when divided by a center console, and thus lacking a free-standing ...

Bárány Chair
The Barany chair or Bárány chair is a device used for aerospace physiology training, particularly for student pilots. Test The subject is placed in the swivel chair, blindfolded, then spun about the vertical axis while keeping their head upright or tilted forward or to the side. The subject is then asked to perform tasks such as determine their direction of rotation while blindfolded, or rapidly change the orientation of their head, or attempt to point at a stationary object without blindfold after the chair is stopped. The chair is used to demonstrate spatial disorientation effects, proving that the vestibular system is not to be trusted in flight. Pilots are taught that they should instead rely on their flight instruments. Uses The device is also used in motion sickness therapy. Nobel Prize The chair was named for Hungarian physiologist Robert Bárány, who used this device in his research into the role of the inner ear in the sense of balance. He won the 1914 Nobel Prize ...

Armrest
An armrest (or arm-rest) is a part of a chair, where a person can rest their arms on. Armrests are built into a large variety of chairs such as automotive chairs, armchairs, airline seats, sofas, and more. Adjustable armrests are commonly found in ergonomic office chairs and gaming chairs. In automobiles Armrest is also a feature found in most modern automobiles on which the occupants can rest their arms. Armrests are commonly placed between the front car seats on the driver and passenger side of the vehicle. Sometimes one or two armrests may also be attached to each individual seat, a feature commonly found in minivans (MPVs) and some SUVs. Many larger cars also have a broad arm-rest between the back seats, which may be folded out when the central (third) seating place is not required. In some designs where occupant safety is emphasised, including some Volvo models, the armrest doubles as a child seat, complete with specially adjustable seatbelt. Armrests in some veh ...

Sash Window
A sash window or hung sash window is made of one or more movable panels, or "sashes". The individual sashes are traditionally paned windows, but can now contain an individual sheet (or sheets, in the case of double glazing) of glass. History The oldest surviving examples of sash windows were installed in England in the 1670s, for example at Palace House, and Ham House.Louw, HJ, ''Architectural History'', Vol. 26, 1983 (1983), pp. 49–72, 144–15JSTOR The invention of the sash window is sometimes credited, without conclusive evidence, to Robert Hooke. Others see the sash window as a Dutch invention. H.J. Louw believed that the sash window was developed in England, but concluded that it was impossible to determine the exact inventor. The sash window is often found in Georgian and Victorian houses, and the classic arrangement has three panes across by two up on each of two sash, giving a ''six over six'' panel window, although this is by no means a fixed rule.
