Stairway
Stairs are a structure designed to bridge a large vertical distance between lower and higher levels by dividing it into smaller vertical distances. This is achieved as a diagonal series of horizontal platforms called steps which enable passage to the other level by stepping from one to another step in turn. Steps are very typically rectangular. Stairs may be straight, round, or may consist of two or more straight pieces connected at angles. Types of stairs include staircases (also called stairways), ladders, and escalators. Some alternatives to stairs are elevators (also called lifts), stairlifts, inclined moving walkways, and ramps. A stairwell is a vertical shaft or opening that contains a staircase. A flight (of stairs) is an inclined part of a staircase consisting of steps (and their lateral supports if supports are separate from steps). Components and terms A ''stair'', or a ''stairstep'', is one step in a flight of stairs.R.E. Putnam and G.E. Carlson, ''Architectural ...

Escalator
An escalator is a moving staircase which carries people between floors of a building or structure. It consists of a motor-driven chain of individually linked steps on a track which cycle on a pair of tracks which keep the step tread horizontal. Escalators are often used around the world in places where lifts would be impractical, or they can be used in conjunction with them. Principal areas of usage include department stores, shopping malls, airports, transit systems (railway/railroad stations), convention centers, hotels, arenas, stadiums and public buildings. Escalators have the capacity to move large numbers of people. They have no waiting interval (except during very heavy traffic). They can be used to guide people toward main exits or special exhibits and may be weatherproofed for outdoor use. A non-functional escalator can function as a normal staircase, whereas many other methods of transport become useless when they break down or lose power. Design, component ...

Baluster
A baluster is an upright support, often a vertical moulded shaft, square, or lathe-turned form found in stairways, parapets, and other architectural features. In furniture construction it is known as a spindle. Common materials used in its construction are wood, stone, and less frequently metal and ceramic. A group of balusters supporting a handrail, coping, or ornamental detail are known as a balustrade. The term baluster shaft is used to describe forms such as a candlestick, upright furniture support, and the stem of a brass chandelier. The term banister (also bannister) refers to a baluster or to the system of balusters and handrail of a stairway. It may be used to include its supporting structures, such as a supporting newel post. Etymology According to the ''Oxford English Dictionary'', "baluster" is derived through the french: balustre, from it, balaustro, from ''balaustra'', "pomegranate flower" rom a resemblance to the swelling form of the half-open flower (''i ...

Stairlift
A stair lift is a mechanical device for lifting people, typically those with disabilities, up and down stairs. For sufficiently wide stairs, a rail is mounted to the treads of the stairs. A chair or lifting platform is attached to the rail. A person gets onto the chair or platform and is lifted up or down the stairs by the chair which moves along the rail. Stair lifts are known variously as stairlifts, stair-lifts, chair lifts, stair gliders and by other names. This type of chair lift should not be confused with the chairlift used by skiers. The term stair climber can refer either to stair lifts, or more commonly to the exercise equipment by the same name. Some of the first stair lifts to be produced commercially were advertised and sold in the U.S. in the 1930s by the Inclinator Company of America. Many users at the time were victims of polio. Now they are seen for use in elderly, fall-prone individuals, and disabled people who are unable to navigate stairs safely. History In ...

Ladder
A ladder is a vertical or inclined set of rungs or steps used for climbing or descending. There are two types: rigid ladders that are self-supporting or that may be leaned against a vertical surface such as a wall, and rollable ladders, such as those made of rope or aluminium, that may be hung from the top. The vertical members of a rigid ladder are called stringers or rails (US) or stiles (UK). Rigid ladders are usually portable, but some types are permanently fixed to a structure, building, or equipment. They are commonly made of metal, wood, or fiberglass, but they have been known to be made of tough plastic. Historical usages Ladders are ancient tools and technology. A ladder is featured in a Mesolithic rock painting that is at least 10,000 years old, depicted in the Spider Caves in Valencia, Spain. The painting depicts two humans using a ladder to reach a wild honeybee nest to harvest honey. The ladder is depicted as long and flexible, possibly made out of some sort ...

Elevator
An elevator or lift is a cable-assisted, hydraulic cylinder-assisted, or roller-track assisted machine that vertically transports people or freight between floors, levels, or decks of a building, vessel, or other structure. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist, although some pump hydraulic fluid to raise a cylindrical piston like a jack. In agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket elevator, grain auger screw conveyor using the principle of Archimedes' screw, or the chain and paddles or forks of hay elevators. Languages other than English, such as Japanese, may refer to elevators by loanwords based on either ''elevator'' or ''lift''. Due to wheelchair access laws, elevators are often a legal requirement in new multistory buildings, especi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winchester Mystery House
The Winchester Mystery House is a mansion in San Jose, California, that was once the personal residence of Sarah Winchester, the widow of firearms magnate William Wirt Winchester. The house became a tourist attraction nine months after Winchester's death in 1922. The Victorian and Gothic style mansion is renowned for its size and its architectural curiosities. It is sometimes claimed to be one of the “most haunted places in the world”, but there is no evidence to support this belief. Much of the lore regarding the Winchester House and its owner is fanciful, unverified, and often provably false. Sarah Winchester Sarah Winchester, always called Sallie, after her paternal grandmother, was born in 1839 in New Haven, Connecticut. She married William Wirt Winchester in 1862. In 1866, Winchester gave birth to a baby girl whom they named Annie Pardee Winchester. The baby did not thrive, and was diagnosed with marasmus and died a month after birth. Between the fall of 1880 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newel
A newel, also called a central pole or support column, is the central supporting pillar of a staircase. It can also refer to an upright post that supports and/or terminates the handrail of a stair banister (the "newel post"). In stairs having straight flights it is the principal post at the foot of the staircase, but the term can also be used for the intermediate posts on landings and at the top of a staircase. Although its primary purpose is structural, newels have long been adorned with decorative trim and designed in different architectural styles. Newel posts turned on a lathe are solid pieces that can be highly decorative, and they typically need to be fixed to a square newel base for installation. These are sometimes called solid newels in distinction from hollow newels due to varying techniques of construction. Hollow newels are known more accurately as box newel posts. In historic homes, folklore holds that the house plans were placed in the newel upon completion of the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob's Ladder
Jacob's Ladder ( he, סֻלָּם יַעֲקֹב ) is a ladder leading to heaven that was featured in a dream the biblical Patriarch Jacob had during his flight from his brother Esau in the Book of Genesis (chapter 28). The significance of the dream has been debated, but most interpretations agree that it identified Jacob with the obligations and inheritance of the people chosen by God, as understood in Abrahamic religions. Biblical narrative The description of Jacob's Ladder appears in : Judaism The classic Torah commentaries offer several interpretations of Jacob's Ladder. According to the Midrash Genesis Rabbah, the ladder signified the exiles which the Jewish people would suffer before the coming of the Jewish messiah. First, the angel representing the 70-year exile of Babylonia climbed "up" 70 rungs, and then fell "down". Then the angel representing the exile of Persia went up a number of steps, and fell, as did the angel representing the exile of Greece. Only the ...

Stair Tread
A stair tread is the horizontal portion of a set of stairs on which a person walks. The tread can be composed of wood, metal, plastic, or other materials. In residential settings, treads can be covered in carpeting. Stair treads can come in non-slip varieties, particularly in commercial or industrial locations. Styles of tread There are a number of different styles of tread: Mid flight treads. ;Straight or flier.: A standard oblong shaped tread. used in a straight flight. ;Diminishing flier.: Set into the straight section of flight before a turn, with one end narrower than the other Used to change the pitch of the handrail before a 180º turn. ;Winder.: wider at one end, used to turn the flight. ;Kite winder.: A quadrilateral shaped tread, used in the corner of a turn: hence the kite name. Feature or starting treads. These treads are used to embellish the start of a flight of stairs, they may have either a straight front to them or a commode/curved front to enhance them furt ...
