Abstract:
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 ).
