Door
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a ''doorway'' or ''portal''. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing. The door may be able to move in various ways (at angles away from the doorway/portal, by sliding on a plane parallel to the frame, by folding in angles on a parallel plane, or by spinning along an axis at the center of the frame) to allow or prevent ingress or egress. In most cases, a door's interior matches its exterior side. But in other cases (e.g., a vehicle door) the two sides are radically different. Many doors incorporate lockin ...

Ventilation (architecture)
Ventilation is the intentional introduction of outdoor air into a space. Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort, satisfaction with other aspects of indoor environment, or other objectives. The intentional introduction of outdoor air is usually categorized as either mechanical ventilation, natural ventilation, or mixed-mode ventilation (hybrid ventilation). * Mechanical ventilation is the intentional fan driven flow of outdoor air into a building. Mechanical ventilation systems may include supply fans (which push outdoor air into a building), exhaust fans (which draw air out of building and thereby cause equal ventilation flow into a building), or a combination of both. Mechanical ventilation is often provided by equipment that is also used to heat and cool a space. * Natural ventilation is the intentional passive ...

Doorbell
A doorbell is a signaling device typically placed near a door to a building's entrance. When a visitor presses a button, the bell rings inside the building, alerting the occupant to the presence of the visitor. Although the first doorbells were mechanical, activated by pulling a cord connected to a bell, modern doorbells are electric, operated by a pushbutton switch. Modern doorbells often incorporate intercoms and miniature video cameras to increase security. History William Murdoch, a Scottish inventor, installed a number of his own innovations in his house, built in Birmingham in 1817; one of these was a loud doorbell, that worked using a piped system of compressed air. A precursor to the electric doorbell, specifically a bell that could be rung at a distance via an electric wire, was invented by Joseph Henry around 1831. By the early 1900s, electric doorbells had become commonplace. Wired doorbells In most wired systems, a button on the outside next to the door, locate ...

Hinge
A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation: all other translations or rotations being prevented, and thus a hinge has one degree of freedom. Hinges may be made of flexible material or of moving components. In biology, many joints function as hinges, like the elbow joint. History Ancient remains of stone, marble, wood, and bronze hinges have been found. Some date back to at least Ancient Egypt. In Ancient Rome, hinges were called cardō and gave name to the goddess Cardea and the main street Cardo. This name cardō lives on figuratively today as "the chief thing (on which something turns or depends)" in words such as ''cardinal''. According to the OED, the English word hinge is related to '' hang''. Door hinges ; Barrel hinge: A barrel hinge consists of a sectional barrel (the ...

Frame And Panel
Frame and panel construction, also called rail and stile, is a woodworking technique often used in the making of doors, wainscoting, and other decorative features for cabinets, furniture, and homes. The basic idea is to capture a 'floating' panel within a sturdy frame, as opposed to techniques used in making a slab solid wood cabinet door or drawer front, the door is constructed of several solid wood pieces running in a vertical or horizontal direction with exposed endgrains. Usually, the panel is not glued to the frame but is left to 'float' within it so that seasonal movement of the wood comprising the panel does not distort the frame. Frame and panel construction at its most basic consists of five members: the panel and the four members which make up the frame. The vertical members of the frame are called stiles while the horizontal members are known as rails. A basic frame and panel item consists of a top rail, a bottom rail, two stiles, and a panel. This is a common metho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Key (lock)
A lock is a mechanical or electronic fastening device that is released by a physical object (such as a key, keycard, fingerprint, RFID card, security token or coin), by supplying secret information (such as a number or letter permutation or password), by a combination thereof, or it may only be able to be opened from one side, such as a door chain. A key is a device that is used to operate a lock (to lock or unlock it). A typical key is a small piece of metal consisting of two parts: the '' bit'' or ''blade'', which slides into the keyway of the lock and distinguishes between different keys, and the ''bow'', which is left protruding so that torque can be applied by the user. In its simplest implementation, a key operates one lock or set of locks that are keyed alike, a lock/key system where each similarly keyed lock requires the same, unique key. The key serves as a security token for access to the locked area; locks are meant to only allow persons having the correct key t ...

Solomon's Temple
Solomon's Temple, also known as the First Temple (, , ), was the Temple in Jerusalem between the 10th century BC and . According to the Hebrew Bible, it was commissioned by Solomon in the United Kingdom of Israel before being inherited by the Kingdom of Judah in . It stood for around four centuries until it was destroyed by the Neo-Babylonian Empire during the Babylonian siege of Jerusalem, which occurred under the reign of Babylonian king Nebuchadnezzar II. Although most modern scholars agree that the First Temple existed on the Temple Mount in Jerusalem by the time of the Babylonian siege, there is significant debate over the date of its construction and the identity of its builder. The Hebrew Bible, specifically within the Book of Kings, includes a detailed narrative about the construction's ordering by Solomon, the penultimate ruler of amalgamated Israel and Judah. It further credits Solomon as the placer of the Ark of the Covenant in the Holy of Holies, a windo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wall
A wall is a structure and a surface that defines an area; carries a load; provides security, shelter, or soundproofing; or, is decorative. There are many kinds of walls, including: * Walls in buildings that form a fundamental part of the superstructure or separate interior rooms, sometimes for fire safety *Glass walls (a wall in which the primary structure is made of glass; does not include openings within walls that have glass coverings: these are windows) * Border barriers between countries * Brick walls * Defensive walls in fortifications * Permanent, solid fences * Retaining walls, which hold back dirt, stone, water, or noise sound * Stone walls * Walls that protect from oceans ( seawalls) or rivers ( levees) Etymology The term ''wall'' comes from Latin ''vallum'' meaning "...an earthen wall or rampart set with palisades, a row or line of stakes, a wall, a rampart, fortification..." while the Latin word ''murus'' means a defensive stone wall.

Room
In a building or large vehicle, like a ship, a room is any enclosed space within a number of walls to which entry is possible only via a door or other dividing structure that connects it to either a passageway, another room, or the outdoors, that is large enough for several people to move about, and whose size, fixtures, furnishings, and sometimes placement within the building or ship support the activity to be conducted in it. History Historically, the use of rooms dates at least to early Minoan cultures about 2200 BC, where excavations at Akrotiri on Santorini reveal clearly defined rooms within certain structures. In early structures, the different room types could be identified to include bedrooms, kitchens, bathing rooms, closets, reception rooms, and other specialized uses. The aforementioned Akrotiri excavations reveal rooms sometimes built above other rooms connected by staircases, bathrooms with alabaster appliances such as washbasins, bathing tubs, and toilets ...

Black Rod
Black Rod (officially known as the Lady Usher of the Black Rod or, if male, the Gentleman Usher of the Black Rod) is an official in the parliaments of several Commonwealth countries. The position originates in the House of Lords of the Parliament of the United Kingdom. The position is similar to one known as a serjeant-at-arms in other bodies. In the United Kingdom, Black Rod is principally responsible for controlling access to and maintaining order within the House of Lords and its precincts, as well as for ceremonial events within those precincts. Since early 2018, the post has been held for the first time by a woman, Sarah Clarke. Origin The office was created in 1350 by royal letters patent, though the current title dates from 1522. The position was adopted by other members of the Commonwealth when they adopted the British Westminster system. The title is derived from the staff of office, an ebony staff topped with a golden lion, which is the main symbol of the offi ...

Building
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much art ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
