Building access Since at least medieval times there have been hinges to draw bridges for defensive purposes for fortified buildings. Hinges are used in contemporary architecture where building settlement can be expected over the life of the building. For example, the Dakin Building in Brisbane, California, was designed with its entrance ramp on a large hinge to allow settlement of the building built on piles over bay mud. This device was effective until October 2006, when it was replaced due to damage and excessive ramp slope.
Pocket door : A pocket door is a sliding door that disappears, when fully open, into a compartment in the adjacent wall. Pocket doors are used for architectural effect, or when there is no room for the swing of a hinged door. They can travel on rollers suspended from an overhead track or also feature tracks or guides along the floor. Both single- and double-door versions are used, depending on how wide an entry is desired.
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.
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.
