Continuous Hinges Terminology

Plain Or Standard Assembly
Neither leaf swaged. Leaves lay flat in the same plane in an open position.

Reverse Assembly
Neither leaf swaged with opposing leaves extending laterally from opposite sides of the pin. Leaves will not close to a parallel position.

Hinge Length
The length of the hinge measured parallel to the pin.

The portion of a hinge extending laterally from the knuckle which generally revolves around a pin.

Leaf Width
The dimension from the center of the pin to the outer edge of the leaf.

The hollow circular part at the joint of a hinge through which a pin is passed (other terms for this are loop, joint, node and curl).

Inside Knuckle Diameter
Also called pin diameter.

Knuckle Length
The dimension of the knuckle measured parallel to the pin.

Paint Clearance
The minimum dimension between the outer face of the knuckle and the opposing edge of the cutout over the entire range of pivotal movement of the hinge.

End Play
The amount of axial movement between the leaves.

The dimension from a point on the knuckle to the same point on an adjacent knuckle on the same leaf.

Forming one or both leaves within the proximity of the paint clearance toward or beyond the center of the pin (swaging slightly increases the width of a hinge when open).

One Leaf Half Swaged
One leaf half the pin diameter.

One Leaf Full Swaged
One leaf swaged equal to the pin diameter and both leaves parallel when in closed position.
Continuous Hinge - One Leaf Full Swaged

Reversed Swaged
One leaf swaged to simulate reverse assembly. Leaves will not close to a parallel position.
Continuous Hinge - Reverse Swaged

Both Leaves Half Swaged
Both leaves swaged approximately one half the pin diameter with a minimum clearance between the leaves when parallel.
Continuous Hinge - Both Leaves Half Swaged

Center Swaged
Both leaves swaged by one half the pin diameter plus one half the material thickness so that both leaves are symmetrical on the center line.

Forming one or both leaves in the proximity of the paint clearance away from the center of the pin. When both leaves are offset and in a closed and parallel position, the dimension between the leaves will be greater than the pin diameter.

Stop Hinge
A hinge manufactured to limit the travel of the leaves to a specified angle.

Stop Hinge, Outside
Leaves will move from an open or flat position and stop at a specified angle.

Stop Hinge, Inside
Leaves will open from a closed position (leaves parallel to each other) to a stop angle as specified.

Continuous Hinge
Mild steel. Plain finish not degreased. Blank no holes stock sizes.
