Claim 0:
1. A hinge for mounting a door or window sash to a frame, the hinge comprising:
a frame part adapted to be fixed to the frame, the frame part including:
a frame mounting part having a cavity,
a frame body mounted in the cavity, and
the frame body including a first recess and a second recess;

a door or sash part adapted to be fixed to the door or sash, the door or sash part including:
a movable door or sash mounting part,
a sash body connected to the movable door or sash mounting part, and
a sash movable body slidably mounted by a slidable mounting arrangement on the sash body, the sash movable body including a first recess and a second recess;

a rotational lever-arm system connected between the frame body and the sash movable body that is at least partially located in the first recesses of the frame body and the sash movable body, the rotational lever-arm system including:
a frame lever-arm including a FB side and a SMB side and a medial position located at a point between the FB side and the SMB side,
a sash lever-arm including a FB side and a SMB side and a medial position located at a point between the FB side and the SMB side of the sash lever-arm,
a rotational pin connecting the frame lever-arm at the frame lever-arm medial position to the sash lever-arm at the sash lever-arm medial position for pivoting movement,
a first rotational arm pin that pivotally connects the SMB side of the frame lever-arm to the sash movable body,
a second rotational arm pin that pivotally connects the FB side of the sash lever-arm to the frame body,
a FB guide projection on the FB side of the frame lever-arm that is received in a FB rotation guide groove in the first recess of the frame body, and
a SMB guide projection on the SMB side of the sash lever-arm that is received in a SMB rotation guide groove in the first recess of the sash movable body;

a first translational arm system connected between the frame body, the sash movable body and the sash body, the first translational arm system being at least partially located in the second recesses of the frame body and the sash movable body and including:
a translational first lever-arm having a first end and a second end,
a translational second lever-arm having a FB side and a SB side, a translational FB guide projection located on the FB side of the translational second lever-arm, a translational first lever-arm pivot connection point located between the FB side and the SB side of the translational second lever-arm, and a sash body pivot connection point located at the SB side,
a first translational pin that pivotably connects the first end of the translational first lever-arm to the translational first lever-arm pivot connection point on the translational second lever-arm,
a second translational pin that pivotably connects the second end of the translational first lever-arm to the sash movable body,
a third translational pin that pivotably connects the sash body pivot connection point of the translational second lever-arm to the sash body, and
the translational guide projection on the FB side of the translational second lever-arm is received in a translational guide groove in the second recess of the frame body; and
wherein the first, second, and third translational pins and the first and second rotational arm pins extend along axes that are parallel to one another.
