Patent ID: 8826621

Claim:
A mechanism for the adjustment of the vertical alignment of a panel, a first edge of the panel contained within an elongated channel section, the elongate channel section having: an open top; an inside surface, having opposing side walls spaced from one another by a section width; a base connecting the side walls and located below the open top by a section depth; and a section length at right angles to the section width and the section depth; the mechanism comprising: one or more support means for supporting the first edge of the panel within the channel section parallel to the section length of the elongate channel section the support means comprising distal, and opposing, faces, the support means configured to be arranged within the elongate channel section such that the faces are substantially parallel to the opposing side walls of the inside surface, such that the faces abut opposing sides of the panel adjacent to the first edge; one or more clamping parts for clamping the panel with an adjustable force, the one or more clamping parts arranged to adjustably tilt and secure the panel so as to be maintainable substantially vertically aligned even when the elongated channel section is secured to a surface which is not substantially horizontal, the one or more clamping parts comprising: a threaded screw fastening having an axial length, the threaded screw fastening arrangable between the distal faces of the support means and the opposing side walls of the elongated channel section, such that the axial length of the threaded screw fastening is parallel to the section length of the elongated channel section; a number of discrete abutting sliding wedge segments threaded on the threaded screw fastening; and a nut arranged on the threaded screw fastening to squeezes together the sliding wedge segments when tightened; wherein the one or more clamping parts are configured such that as the nut is tightened on the threaded screw fastening, the sliding wedge segments slide in opposite directions at right angles to and away from the axial length, thereby creating a clamping force that urges one of the faces of the support means against one of the sides of the panel adjacent to the first edge, and urges the one of the faces away from one of the side walls of the elongate channel section the clamping force being adjustable by means of varying the distance between the one of the faces of the support means and the one of the side walls of the inside surface of the elongated channel section and the distance between the one of the side faces of the support means and the one of the side walls of the inside surface of the elongated channel section being adjustable by means of turning the nut on the threaded screw fastening.
