Hinge, especially for insect screen door, has return sleeves with cooperating runner surfaces for automatically closing door

摘要

Two return sleeves (16, 18) are mounted on the hinge bolt (10) in between the hinge sleeves (20). Runner surfaces (26) at the ends of the return sleeves are in contact with each other. The sleeves generate a return force, causing the open door to close automatically. The hinge comprises two parts (12, 14) connected via hinge sleeves to a single hinge bolt.
