US Patent 9528278 Panel, covering and method for installing such panels

A panel for forming a covering, more particularly a floor panel for forming a floor covering, which at least at two opposite edges, comprises coupling parts arranged to couple two of such panels to each other by means of a downward movement of one panel in respect to the other. The coupling parts form a first locking system arranged to lock in the plane of the panels and perpendicularly to the edges, as well as form a second locking system, which effects a locking perpendicularly to the plane of the panels. At least one of the coupling parts is formed at least partially from soft PVC (polyvinyl chloride), as well as at least partially formed from a milled profiled part of the soft PVC.
