Device for laterally guiding the upper end of a pull-out furniture part

A device for lateral guidance of the upper end of a pull-out furniture part (2), which can be pulled out from a position completely pushed into a furniture body (1) in a pull-out direction (8) to a position completely pulled out of the furniture body (1), comprising:

• a guide rail (4) which can be fastened to the furniture body (1) and the longitudinal extent of which is parallel to the pull-out direction (8);
• a rotary part (7) which is guided by the guide rail (4) parallel to the pull-out direction (8) and which is mounted on a mounting part (6) which can be fastened to the pull-out furniture part, the rotary part (7) pivotable about a horizontal axis of rotation (20) lying at right angles to the pull-out direction (8), wherein the mounting part (6) is movable relative to the guide rail (4) from a push-in position, which can be occupied by the mounting part (6) in the fully push-in position of the pull-out furniture part (2), in the pull-out direction (8) via a displacement path up to a pull-out position which can be occupied by the pull-out furniture part (2) in the fully pull-out position, and wherein, in the push-in position of the mounting part (6), the rotary part (7) rests against a push-in end stop (13a) of the guide rail (4) and assumes a push-in rotational position relative to the mounting part (6) and, in the pull-out position of the mounting part (6), rests against a pull-out end stop (14a) of the guide rail (4) and assumes a pull-out rotational position relative to the mounting part (6), which is rotated about the axis of rotation (20) relative to the push-in rotational position;
• and
• wherein, when the mounting part (6) is displaced, starting from the push-in position in the pull-out direction (8) over an initial section of the displacement path, the rotary part (7) is rotated about the axis of rotation (20) relative to the mounting part (6) by the interaction of the rotary part (7) with a first engagement element (13) of the guide rail (4) and, during the displacement of the mounting part (6) over a main section of the displacement movement following the engagement section, the rotational position of the rotary piece (7) about the axis of rotation (20) remains unchanged relative to the mounting part (6).
