Door hinge with an integrated locking device

A door hinge with an integrated locking device for yielding positioning of a door at predetermined angles relative to a frame comprising:

• a first hinge part having a base plate with integral, upstanding legs at or adjacent one end of the base plate;
• a bending spring;
• a second door-side hinge part having plural rollers attached thereto in a rotatable manner;
• a hinge shaft for rotatably securing the second hinge part to the first hinge part;
• wherein at least one of the plurality of rollers deforms the bending spring when the second hinge part is swivelled relative to the first hinge part;
• wherein the bending spring is configured to have three U-shaped sections, a first U-shaped section comprising a transverse section positioned along the one end of the base plate and two parallel legs adjoining the transverse section at an approximate angle of 90.degree., a second U-shaped section connected to one of the parallel legs, and a 180.degree. bend and with end leg extending therefrom, and a third U-shaped section connected to the other parallel leg and configured with a 180.degree. bend and an end leg extending therefrom, the end legs being connected to an opposite end of the base plate;
• wherein the two parallel legs of the bending spring extend essentially in parallel to sides of the base plate of the first hinge part;
• and
• wherein the bending spring is mounted to the first hinge part in an unstressed condition.
