Patent ID: 8156619

Claim:
A method of making a door hinge, the method comprising the steps of: forming a region of a piece of sheet metal with a groove; bending the piece of sheet metal to form the region into a first eye that is not completely closed with the groove opening inwardly into the first eye; bending the piece of sheet metal to form a second eye spaced from and aligned with the first eye, the piece of sheet metal with the first and second eyes forming a first leaf; providing a second leaf with a third eye fittable between the first and second eyes of the first leaf; fitting the third eye of the second leaf between the first and second eyes of the first leaf with all the eyes aligned and coaxial and forming a pivot open at both ends; longitudinally compressing a pivot pin so as to form it with a radially outwardly projecting thickened region forming a circumferential ridge; fitting the pin to all of the eyes and pressing the ridge into the first eye such that the ridge radially elastically widens the first eye and fits into the groove thereof; and radially and elastically springing back the first eye when the ridge of the pivot pin reaches the inwardly open groove so that the ridge is captured in the groove and the pivot pin is then held in the first eye.
