Types of vehicle doors : There are many different types of vehicle doors, including the following: Conventional doors : A conventional door, also known as a regular door is a type of door that is hinged at the front-facing edge of the door, and so allows the door to swing outward from the body of the car. These doors are relatively safe, in that if they are opened during forward motion of the vehicle, the wind resistance will work against the opening door, and will effectively force its closure. The operation of a vehicle door entering, exiting, or standing out side an opened vehicle door is extremely dangerous particularly at night even when looking both ways. The issue is the vehicle door in most cases provides not visual warning to other vehicle drivers to allow accident avoidance of another vehicle driver to have the time to take avoidance measures. New advancements have been made to allow the viewing of the opened vehicle door at night with the addition of highly reflective tape applied to the lower interior edge of the vehicle door ( see US Patent No. 9,308,859 ). These new advancements allow the opened vehicle door to be seen even with a person blocking the prior art systems such as a reflector or a light by providing reflex reflectivity exceeding fifty percent of the vehicle door behind a person legs blocking the opened vehicle door at night. Disappearing doors : A disappearing door is a type the slides down and under the vehicle. This type makes the whole side of the passenger compartment open, and only leaves a threshold to step over to get in and out. Also called the Jatech rotary drop door, or disappearing car door. One example of a car with disappearing doors is the Lincoln Mark VIII concept car.
Door types There are many types of door hinges. The main types include: Spring hinge a spring-loaded hinge made to provide assistance in the closing or the opening of the hinge leaves. A spring is a component of a hinge, that applies force to secure a hinge closed or keep a hinge opened. Barrel hinge a sectional barrel secured by a pivot. A barrel is a component of a hinge, that has a hollow cylinder shaped section where the rotational bearing force is applied to the pivot, and may also have a screw shaped section for fastening and/or driving the pivot. Pivot hinges which pivot in openings in the floor and the top of the door frame. Also referred to as a double-acting floor hinge. This type is found in ancient dry stone buildings and rarely in old wooden buildings. These are also called haar-hung doors. They are a low cost alternative for use with light weight doors. Butt/Mortise hinges usually in threes or fours, which are inset (mortised) into the door and frame. Most residential hinges found in the U.S. are made of steel, although mortise hinges for exterior doors are often made of brass or stainless steel to prevent corrosion. Case hinges Case hinges are similar to a butt hinge however usually more of a decorative nature most commonly used in suitcases, briefcases and the like. Continuous hinges, or piano hinges This type of hinge is also known as a piano hinge. It runs the entire length of the door, panel, or box. Continuous hinges are manufactured with or without holes. These hinges also come in various thicknesses, pin diameters, and knuckle lengths. Used for furniture doors (with or without self-closing feature, and with or without damping systems). They are made of two parts: One part is the hinge cup and the arm, the other part is the mounting plate. Also called "cup hinge", or "Euro hinge", as they were developed in Europe and use metric installation standards. Most such concealed hinges offer the advantage of full in situ adjustability for standoff distance from the cabinet face as well as pitch and roll by means of two screws on each hinge. Butterfly hinges, or Parliament (UK) Hinges These were known as dovetail hinges from the 17th century onwards and can be found on old desks and cabinets from about 1670 until the 18th century. The form of these hinges varied slightly between manufacturers, and their size ranged from the very large for heavy doors to the tiniest decorative hinge for use on jewellery boxes. Many hinges of this type were exported to America to support the home trades limited supply. They are still found to be both fairly cheap and decorative, especially on small items. Flag hinges A flag hinge can be taken apart with a fixed pin on one leaf. Flag hinges can also swivel a full 360 degrees around the pin. Flag hinges are manufactured as a right hand and a left hand configuration. Strap hinges An early hinge and used on many kinds of interior and exterior doors and cabinets. H hinges Shaped like an H and used on flush-mounted doors. Small H hinges (3–4 in or 76–102 mm) tend to be used for cabinets hinges, while larger hinges (6–7 in or 150–180 mm) are for passage doors or closet doors. HL hinges Large HL hinges were common for passage doors, room doors and closet doors in the 17th, 18th and even 19th centuries. On taller doors H hinges were occasionally used in the middle along with the HL hinges. Other types include: • Counterflap hinge • Flush hinge • Coach hinge • Rising Butt hinge • Double action spring hinge • Double action non-spring • Tee hinge • Friction hinge • Security hinge • Cranked hinge or stormproof hinge • Lift-off hinge • Self closing hinge
