摘要

In a door hinge for hidden placement between a door frame and a door leaf a first hinge rod is rotatably mounted on a door frame receiving body at one end and at another end is guided rotatably and displaceably in a slot link guide of a door leaf receiving body, a second hinge rod is rotatably mounted on the door leaf receiving body at one end and at another end is guided rotatably and displaceably in a slot link guide of the door frame receiving body, disposed at an angle of at least 45° relative to front surfaces of the door leaf in a closed position, and a depth of the door frame receiving body is less than 80% of a depth of the door leaf receiving body.

主权项

1. A door hinge for hidden placement between a door frame and a door leaf, comprising
a door leaf receiving body insertable in a recess in a narrow side of the door leaf, said door leaf receiving body comprising a slot link guide and a receptacle for a leaf-side vertical axis; a door frame receiving body insertable in a recess in an inner side of the door frame, said door frame receiving body comprising a slot link guide and a receptacle for a frame-side vertical axis; a first and a second hinge rod connected in a manner allowing pivoting about a vertical connection axis, wherein said first hinge rod is mounted on said door frame receiving body at one end in a manner allowing rotation about said frame-side vertical axis and at another end is guided rotatably and displaceably in said slot link guide of said door leaf receiving body, wherein said second hinge rod is mounted on said door leaf receiving body at one end in a manner allowing rotation about said door leaf-side vertical axis and at another end is guided rotatably and displaceably in said slot link guide of said door frame receiving body, wherein said first and second hinge rods rotate relative to the vertical axis and are rotatably and replaceably guided in the respective slot link guides during an opening or closing movement of the door leaf, wherein said door frame receiving body and said door leaf receiving body have an offset in a first horizontal direction which extends perpendicularly to front surfaces of the door leaf in a closed position thereof, wherein said slot link guide of said door frame receiving body is the slot link guide selected from the group consisting of a straight slot link guide disposed at an angle of at least 45° relative to front surfaces of the door leaf in a closed position thereof and an arcuate slot link guide, wherein a depth of said door frame receiving body, that is determined in a second horizontal direction perpendicularly to said first horizontal direction with the door leaf closed is less than 80% of a depth of said door leaf receiving body, and wherein the front surfaces of the door leaf define a plane extending in parallel to a longitudinal axis of the door leaf receiving body.
