Abstract

The present superstructure involves, for each upright, a spacer section bar (3), a hinge-bearing section bar (6), a hinge (8), a piston (13) that helps to lift the pane (1), and is completed by a gripper (9) for supporting the pane (1), a closing section bar (11) and a gasket; the section bar (3) has a box section so that it can be adjusted to be joined together with the section bar (6); each hinge (8) is fixed to the section bar (6) and at its end to be fixed to the gripper (9), bears conical guides (8.1) suitable for fitting the conical arms (9.1) situated on the gripper (9) itself; a gasket (12) is fixed to the gripper (9); where spherical panes (1) are involved, hinges (15) are used containing a body (15.1) and a connecting piece (15.2) that can be rotated with respects to the body (15.1) so that the panes (1) can be fitted on at different lengths of the circular arc.

Claims

1. A superstructure for the lifting of panes in display units containing a pane (1) situated on a customer side, which involves, for each upright (2), a spacer section bar (3), a hinge-bearing section bar (6), at least one hinge (8) that is approximately semicircular, at least one piston (13) that helps with the lifting of the pane (1), completed by 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) 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-screws cluster, where the pin (4) is inserted into a hole in the upright (2) and the screws (5) pass through a lower wall of the section bar (3), into the pin (4);

one end of the piston (13) being fixed to the hinge (8);

an other end of the 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) in the case of a back upright;

wherein

the spacer section bar (3) bears bottom fins (3.1) on its lower side that run parallel to its longitudinal axis and bound a bottom guide (3.2), into which a top end of the upright (2) is inserted;

the spacer section bar (3) bears top fins (3.3) on its top side that run parallel to its longitudinal axis and bound a top guide (3.4);

the hinge-bearing section bar (6) contains a guide projection (6.1) in its lower area, which fits 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 section bar (3) are inserted into through slots situated in an area where the two section bars (3, 6) join and fasten together;

the hinge (8) bears conical guides (8.1) on its end that fixes to the gripper (9);

the gripper (9) bears conical arms (9.1), which run parallel to its longitudinal axis, on its end that fixes to the hinge (8);

the arms (9.1) fit into the guides (8.1) on the hinge (8) and the joining together of the two pieces is controlled by

a force exerted by grains (10);

the gripper (9) also bears a groove (9.2), which runs parallel to its longitudinal axis, on its arm that points toward the closing section bar (11);

one end of a plastic gasket (12) fits into the groove (9.2), while the other end runs along the closing section bar (11) itself.

2. A superstructure according to claim 1, wherein the bottom fins (3.1) on the spacer section bar (3) can be present either on both sides of the section bar (3), or only along one side, depending on whether the section bar (3) is being used for central or side uprights.

3. A superstructure according to claim 2, wherein the bottom fins (3.1) are only present along a left or a right side of the spacer section bar (3), to be fixed to left or right side uprights.

4. A superstructure according to claim 1, wherein where the superstructure involves spherical panes (1), hinges (15) are used, each hinge (15) being composed of an approximately semicircular body (15.1) and a connecting piece (15.2);

the body (15.1) bearing an insert (15.3) into which a base of the connecting piece (15.2) fits;

a connection of the body (15.1) to the connecting piece (15.2) being achieved by means of screws that are lodged into holes (15.4, 15.5) present on both of the body (15.1) and the connecting piece (15.2);

conical guides (15.6) that fit the conical arms (9.1) of the gripper (9) being incorporated into the connecting piece (15.2);

a longitudinal axis of each conical guide (15.6) being incident to a longitudinal axis of the body (15.1);

the base of the connecting piece (15.2) being rotatable with respect to the body (15.1) so that the panes (1) can be fitted onto the same hinges (15) at different lengths of a circular arc without interfering with the hinge-bearing section bar (6).

5. A superstructure according to claim 4, wherein where spherical panes (1) are used that involve a different length of the circular arc, the body (15.1) can be replaced without interfering with the hinge-bearing section bar (6).

6. A superstructure according to claim 4, wherein the body (15.1) is hinged onto an adapting piece (15.7) by means of a pin (15.8) that passes through a hole (15.9);

the adapting piece (15.7) being in turn fixed to the section bar (6).

7. A superstructure according to claim 4, wherein the connecting piece (15.2) is made up of a plate onto which a crop of section bar containing conical guides (15.6) is fixed by means of screws.
