Hinge


Hinge
A barrel hinge

A hinge is a type of 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. Hinges may be made of flexible material or of moving components. In biology, many joints function as hinges.

Door hinges

There are many types of door hinges. The main types include:

Barrel hinge
which is 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.
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.
Concealed hinges
used for furniture doors (with or without self-closing feature, and with or without dampening systems). They are made of 2 parts: One part is the hinge cup and the arm; the other part is the mounting plate. Also Euro/cup 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 trade's 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
Strap hinges are 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/76–100 mm) tend to be used for cabinets hinges, while larger hinges (6–7 in/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
  • Tee hinge
  • Friction hinge
  • Security hinge
  • Cranked hinge or stormproof hinge

Building access hinges

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, 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 has been effective.

Drop leaf table hinge
