- The invention relates to a pedestal assembly for elevating a building surface, and more specifically a height-adjustable pedestal assembly for supporting flooring elements such as timber joists, tiles or stones.
- It is common for height-adjustable cylinder-type pedestals to be used for supporting flooring elements over uneven ground surfaces, whereby the height of such pedestals can be adjusted by the relative rotation of threaded cylinders. An array of such pedestals is typically deployed to provide an elevated building surface across the ground for subsequent mounting of flooring elements.
- A problem with conventional pedestals is that rotating threaded cylinders becomes a time-consuming exercise if significant height adjustments are required, and the problem is compounded if adjustments are required across a large array of pedestals. A further drawback is that conventional threaded cylinder pedestals usually cover a relatively narrow range of height increments which means that expensive add-on cylinders would often need to be procured and installed to the pedestals.
