1. A superstructure for lifting of panes (1) in display units containing panes (1) and uprights (2), wherein each pane (1) is situated on a customer side, the superstructure comprising:

  • for each upright (2), a spacer section bar (3), a hinge-bearing section bar (6), at least one hinge (8, 15) that is generally semicircular, at least one piston (13) that helps with the lifting of the pane (1), a gripper (9) for supporting the pane (1), a closing section bar (11) fixed to the hinge-bearing section bar (6), and a gasket, the hinge-bearing section bar (6) being fixed above the section bar (3) by means of screws (7), each hinge (8, 15) being hinged onto the section bar (6) by means of a pin (8.1), the upright (2), front or back, being fixed to the spacer section bar (3) by means of a pin and screws assembly wherein a pin (4) is inserted into a hole in the upright (2) and screws (5) pass through a lower wall of the spacer section bar (3) into the pin (4), one end of the at least one piston (13) being fixed to the hinge (8, 15), an other end of the at least one piston (13) being fixed onto a bracket (14) fixed to the upright (2) when a front upright is involved or directly to the upright (2) when a back upright is involved, the spacer section bar (3) bearing bottom fins (3.1) on a lower side of the spacer section bar (3) that run parallel to a longitudinal axis of the spacer section bar (3), the bottom fins (3.1) bounding a bottom guide (3.2) into which a top end of the upright (2) is inserted, the spacer section bar (3) bearing top fins (3.3) on a top side of the spacer section bar (3) that run parallel to the longitudinal axis of the spacer section bar (3), the top fins (3.3) bounding a top guide (3.4), the hinge-bearing section bar (6) containing a guide projection (6.1) on a lower area of the hinge-bearing section bar (6), the guide projection (6.1) fitting into the top guide (3.4) on the spacer section bar (3), the screws (7) that fix the hinge-bearing section bar (6) to the spacer section bar (3) being inserted into slots situated in an area where the two section bars (3, 6) join and fasten together, an end of the hinge (8, 15) fixed to the gripper (9) bearing conical guides (8.2, 15.6), an end of the gripper (9) fixed to the hinge (8, 15) having conical arms (9.1), the conical arms (9.1) running parallel to a longitudinal axis of the gripper (9), the arms (9.1) fitting into the guides (8.2, 15.6) on the hinge (8, 15) so the joining together of the gripper (9) and the hinge (8, 15) is controlled by grains (10), the gripper (9) having a groove (9.2) which runs parallel to the longitudinal axis of the gripper (9) on an arm of the gripper (9) that points toward the closing section bar (11), one end of a plastic gasket (12) fitting into the groove (9.2), an other end of the plastic gasket (12) running along the closing section bar (11).
