HINGE COLLAR/HINGE

Collars can be found in all types of restaurant equipment and are common accessories to other components. A collar is a restraining or connecting band, ring, flange, or pipe in machinery used to restrain motion, hold something in place, or join two or more parts together. Mechanical collars often hold bearings and sprockets on shafts, situate components in motor and gearbox assemblies, and serve as mechanical stops. Collars may also be used on cups and containers, blending pitchers and more.

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.
