A door hinge device (1) of the snap-in type, wherein a hinge leaf (7) is designed to be secured in a door frame (4), and wherein a second hinge leaf (8) has a hole (10) designed for snap engagement with a snap-in catch (6) when the second hinge leaf (8) is inserted into a receiving part (5; 15) secured to a door leaf (3). In front of the free end (6''') of the snap-in catch (6) there is an open portion (11). A leaf spring (14) in the shape of an arch or a shallow V spans across said portion (11) transverse to the direction of motion of the hinge leaf (8) inside the receiving part (5; 15). When the snap-in catch (6) is in engagement with said hole (10) <u>either</u> a portion (8''') of the second hinge leaf (8) will be yieldingly supported by the leaf spring (14) on a side (14'') thereof facing away from the door leaf (3), a piece (8'') of the hinge material on the second hinge leaf (8) located between its hole (10) and its free end edge (8') forming a pivotal connection with a root portion (6'') of the snap-in catch (6) when the second hinge leaf (8) is turned out of the plane of the receiving part (5; 15), <u>or</u> edge portions (8'''') of the second hinge leaf (8) will form non-yielding abutment with the opposite side (14') of the leaf spring (14). |
