Door hinge for a laboratory instrument door

A door hinge for a laboratory instrument door comprising:

• a hollow body with a first longitudinal axis, wherein the hollow body comprises a curved side wall, wherein the curved side wall comprises a track that defines a first section, a second section and a moving section that connects the first section with the second section and is inclined relative to the first longitudinal axis;
• a linear guiding element with a second longitudinal axis parallel to the first longitudinal axis, wherein at least a part of the linear guiding element is arranged in the hollow body, wherein the linear guiding element and the hollow body are rotatable against each other;
• and
• a body comprising a protruding pin, wherein the body is movably attached to the linear guiding element so that the body is movable in two opposite directions along the second longitudinal axis and the protruding pin is movable on the track wherein the second section is oriented in a right angle relative to the first longitudinal axis so that the protruding pin is stopped and held on the second section, wherein the door hinge further comprises a force generator configured to exert a force on the body for moving the body in a first direction of the two opposite directions, wherein the force generator is an elastic member connecting the linear guiding element with the body, wherein the force generates a tension relaxation within the elastic member.
