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.

 

standard assembly

Reverse Assembly

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

reverse asembly

 

Unequal Leaves

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

 

unequal leaves

 

One Leaf Half Swaged

Leaves stay flat in the same plane in an open position.

 

One leaf half swaged

 

Both Leaves Half Swaged

Both leaves swaged approximately one half the pin diameter.

both leaves half swaged

 

One Leaf Fully Swaged

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

one leaf fully swaged

 

One Leaf Reversed Swaged

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

one leaf reverse swaged

 

Offset

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