Abstract:
1. A post, configured to be removably securable in an aperture and having a predetermined first cross-sectional area, the post having: an end portion having an angled face; and a wedge, having a complementary angled face arranged against the angled face of the end portion, which is configured to be slidably movable at the end portion to adjust a second cross-sectional area, defined by the wedge and the end portion, wherein the angled face of the wedge is slidably movable relative to the angled face of the end portion to increase the second cross-sectional area relative to the first cross-sectional area to tightly secure the end portion within an aperture; a mechanism connected to the wedge for slidably moving the angled face of the wedge relative to the angled face of the end portion to increase the second cross-sectional area relative to the first cross-sectional area to tightly secure the end portion within an aperture, wherein the mechanism includes a drawbar which extends from a first part located at the end portion of the post to a second part at a distal end of the post, the distal end being opposite the end portion and remote from the end portion, the drawbar having a threaded portion at the first part, the threaded portion being engageable with the wedge, whereby the rotation of the drawbar causes the wedge to slidably move, wherein the wedge is movable to a position where the second cross-sectional area is smaller than the first cross-sectional area, the drawbar has a longitudinal axis and the wedge is moveable to a position where the angled face of the wedge overlaps the surface of the drawbar when seen in cross-section in a plane which includes the longitudinal axis of the drawbar and a line that is normal to the angled face of the wedge.
