Hinge

Basic hinge

Barrel hinge

A barrel hinge consists of a sectional barrel (the knuckle) secured by a pivot. A barrel is simply a hollow cylinder. The vast majority of hinges operate on the barrel principle.

Butt hinge / Mortise hinge

Any hinge which is designed to be set into a door frame and/ or door is considered to be a butt hinge or a mortise hinge. A hinge can also be made as a half-mortise, in which case only one half of the hinge is mortised and the other is not. Most mortise hinges are also barrel hinges by virtue of how they pivot (i.e., a pair of leaves secured to each other by knuckles through which runs a pin).

Butterfly/ Parliament (UK) hinge

These are a decorative variety of barrel hinge with leaves somewhat resembling the wings of a butterfly

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.

Concealed hinge

These are 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.

Continuous/ Piano hinge

This variety of barrel hinge runs the entire length of a door, panel, box., etc. Continuous hinges are manufactured with or without holes.

Flag hinge

these consist of a single leaf attached (in the male variety) to a pin. When used, the pin is inserted into the other (female) portion of the hinge. This allows the objects to be easily removed from e(for example, a removable door). They are manufactured in right-hand and left-hand configurations.

H hinge

These barrel hinges are 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 hinge

These 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.

Pivot hinge

This hinge pivots 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 lightweight doors.[2]

Self-closing hinge

This is a spring-loaded hinge with speed control function. The same as spring hinge, usually use spring to provide force to close the door and provide a mechanical or hydraulic damper to control door close speed. That can prevent door slamming problem while auto closes a door.[3]

Spring hinge

This is 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.[4]

Living hinge

This hinge takes advantage of the flexibility of plastic to create a join between two objects without any knuckles or pins. They are molded as a single piece, never become rusted, do not squeak, and have several other advantages over other hinges, but the plastic makes them more susceptible to breakage.

Other types include:

• Coach hinge
• Counterflap hinge
• Cranked hinge or storm-proof hinge
• Double action non-spring
• Double action spring hinge
• Flush hinge
• Friction hinge
• Lift-off hinge
• Pinge: A hinge with a quick release pin.
• Rising butt hinge
• Security hinge
• Tee hinge

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.

Hinges appear in large structures such as elevated freeway and railroad viaducts. These are included to reduce or eliminate the transfer of bending stresses between structural components, typically in an effort to reduce sensitivity to earthquakes. The primary reason for using a hinge, rather than a simpler device such as a slide, is to prevent the separation of adjacent components. When no bending stresses are transmitted across the hinge it is called a zero moment hinge.

People have developed a variety of self-actuating, self-locking hinge designs for spacecraft deployable structures such as solar array panels, synthetic aperture radar antennas, booms, radiators, etc.[5]

Butler tray hinge

Folds to 90 degrees and also snaps flat. They are for tables that have a tray top for serving.

Carpentier joint

A hinge consisting of several thin metal strips of curved cross section.

Card table hinge

Mortised into edge of antique or reproduction card tables and allow the top to fold onto itself.

Drop-leaf table hinge

Mounted under the surface of a table with leaves that drop down. They are most commonly used with rule joints.

Hinged handcuffs

a restraint device designed to secure an individual's wrists in proximity to each other consisting of two cuffs linked with a double or triple hinge. Hinged handcuffs cuffs tend to restrict movement more than chain-linked handcuffs, and they can be used to generate more leverage to force a suspect's hands behind the back, or to apply pain against the wrist, forcing the subject to comply and stop resisting.[7]

Piano hinge

(or coffin hinge) a long hinge, originally used for piano lids, but now used in many other applications where a long hinge is needed.
