For the adjustable fastening of a glass panel in a receiving groove of an upper frame strip, the former has, in the vicinity of the two ends of the upper edge region, circular holes through which fastening elements are inserted. Each fastening element consists of a tie part (5) with an outer surface (13) which is approximately cylindrically symmetrical about an adjusting axis (12) and which is meshed with an inner surface (14) of a holding part (6) slipped onto the tie part (5). The tie part (5) engages with axially projecting tie pins (8) into continuous tie grooves made laterally in the receiving groove. The edge of the hole in the glass panel touches the holding part (6) on an outer contact surface (7) which is rotationally symmetrical about an eccentric axis (15) parallel to the adjusting axis (12) and spaced from the latter by the amount of an eccentricity ( DELTA ). The holding part (6) can be drawn off from the tie part (5) and slipped on again, rotated through a multiple of an increment ( alpha ) about the adjusting axis (12), with the result that the vertical position of the contact surface (7) in relation to the tie part (5) and therefore the position of the glass panel in relation to the frame strip changes. <IMAGE> |
