Hinge
Length: the dimension of the hinge measured parallel to the pin.
Paint
Clearance: the dimension (of space) between the edge of a knuckle and the edge
of the adjacent leaf.
Hinge
Width: the sum of the two leaves' widths. In hinges with equal leaves, twice
the leaf width.
End
Play: the amount of up and down movement between the leaves as determined by
the dimension (of space) between the knuckles.
Knuckle:
the hollow circular part of a hinge that the pin goes through.
Leaf
Width: the dimension from the center of the pin to the outer edge of the leaf.
On hinges with equal leaves, leaf width is half of the hinge width.
Pin:
the rod, running the length of the hinge, that holds the leaves together.
Leaf:
the part of a hinge that extends from the knuckle and revolves around the pin.
Knuckle
Length: the dimension of a knuckle measured parallel to the pin.
Roll
over the continuous hinge parts below to see their definitions.
Continuous hinges, commonly known as "piano hinges," are hinges that are at least six inches long.
Use this overview of continuous hinges and their parts for quick
reference.
Continuous hinges have many benefits. They are:
strong throughout their entire lengths because each knuckle
is a load bearing point
strengthening: they increase product rigidity by supporting the full
length of the application
easier and more precise to align than two or more butt hinges
attractive and uniform in appearance
smooth in pivotal action, providing optimal axial rotation
low-cost and economical, lasting through many swing cycles
versatile: they are available in many variations, easily customized to suit individual
applications
