Hinge Terminology

HINGE TERMINOLOGY

LENGTH
The length of the leaves measured parallel to the pin.

WIDTH OPEN
The overall dimension of leaves measured across the pin

PIN
The rod running the length of the hinge. The pin holds the leaves of the hinge together.

KNUCKLE
The hollow circular part at the joint of the hinge through which a pin is passed.

KNUCKLE LENGTH
The dimension of the knuckle measured parallel to the pin.

PAINT CLEARANCE
The dimension between the outer face of the knuckle and the opposing edge of the leaf cut-out over the entire range of rotation.

LEAF WIDTH
The dimension from the centre of the pin to the outer edge of the leaf.

END PLAY
The amount of axial movement between leaves.

ASSEMBLY OPTIONS

Standard Assembly
Leaves stay flat in the same plane in a open position.

Side01_208x40

Reverse Assembly
Opposing leaves extend laterally from opposite sides of the pin in the open position. Leaves will not close to parallel position.

Side02_208x40

Unequal Leaves
One leaf is a different width than the other, measured from the centre of the pin.

Side03_208x40

One Leaf Half Swaged
Leaves stay flat in the same plane in an open position.

Side04_204x39

Both Leaves Half Swaged
Both leaves swaged approximately one half the pin diameter.

Side05_204x39

One Leaf Fully Swaged
One leaf swaged equal to the pin diameter and both leaves parallel when in closed position.

Side06_208x40

One Leaf Reversed Swaged
One leaf swaged to simulate reversed assembly. Leaves will not close to parallel position.

Side07_204x104

Offset
Forming of one or both leaves to provide more clearance between the leaves in closed position.
