Sliding door (car) : A sliding door is a type of door is mounted on or suspended from a track for the door to slide, usually horizontally. It is a feature predominately relegated to minibuses and buses to provide a large entrance or exit for passengers without obstructing the adjacent pathway between the vehicle and any adjoining object or the side(s) of passenger and commercial vans so as to allow a larger unobstructed access to the interior for loading and unloading. Sliding doors are often used in mini MPVs such as the Toyota Porte and Peugeot 1007 and Renault Kangoo, but are more commonly used in full-sized MPVs like the Toyota Previa, the Citroën C8, the Peugeot 807, the Chrysler Voyager and the Kia Sedona. Their use has increased over the years as MPVs have increased in popularity, because it gives easy access and makes parking in tight spaces possible. The most common type of sliding door, that has a three-point suspension and opens outwards, then runs along the side of the vehicle, was introduced in 1964 by Volkswagen AG as an option on its Type 2 vans.
Hinge terminology : Components : Pin The rod that holds the leaves together, inside the knuckle. Knuckle The hollow—typically circular—portion creating the joint of the hinge through which the pin is set. The knuckles of either leaf typically alternate and interlock with the pin passing through all of them. (aka. loop, joint, node or curl) Leaf The portions (typically two) that extend laterally from the knuckle and typically revolve around the pin. Characteristics End Play Axial movement between the leaves along the axis of the pin. This motion allows the leaves to rotate without binding and is determined by the typical distance between knuckles (knuckle gap) when both edges of the leaves are aligned. Gauge Thickness of the leaves. Hinge Width Length from the outer edge of one leaf to the outer edge of the other leaf, perpendicularly across the pin(aka open width). Hinge Length The length of the leaves parallel to the pin. Knuckle Length The typical length of an individual knuckle parallel to the pin. Leaf Width Length from the center of the pin to the outer edge of the leaf. Pitch Distance from the end of a knuckle to the same edge of its adjacent knuckle on the same leaf Slop A colloquialism referring to loose angular movement of the leaves relative to the pin.
Applications : Architectural doors have numerous general and specialized uses. Doors are generally used to separate interior spaces (closets, rooms, etc.) for convenience, privacy, safety, and security reasons. Doors are also used to secure passages into a building from the exterior, for reasons of climate control and safety Doors also are applied in more specialized cases: • A Blast-proof door is constructed to allow access to a structure as well as to provide protection from the force of explosions. • A garden door is any door that opens to a backyard or garden. This term is often used specifically for French windows, double French doors (with lites instead of panels), in place of a sliding glass door. The term also may refer to what is known as patio doors • A jib door is a concealed door, whose surface reflects the moldings and finishes of the wall. These were used in historic English houses, mainly as servants doors • A pet door (also known as a cat flap or dog door) is an opening in a door to allow pets to enter and exit without the main doors being opened. It may be simply covered by a rubber flap, or it may be an actual door hinged on the top that the pet can push through. Pet doors may be mounted in a sliding glass door as a new (permanent or temporary) panel. Pet doors may be unidirectional, only allowing pets to exit. Additionally, pet doors may be electronic, only allowing animals with a special electronic tag to enter. • A trapdoor is a door that is oriented horizontally in a ceiling or floor, often accessed via a ladder. • A water door or water entrance, such as those used in Venice, Italy, is a door leading from a building built on the water, such as a canal, to the water itself where, for example, one may enter or exit a private boat or water taxi.
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.
