<p>Each of the castor units is assembled of the wheel (10) with an insertion area (11) for the shaft (30) on top and a lateral positioned brake element (12), a shaft (30) to be inserted into a bore at the piece of furniture (21) and into the appropriate area (11) at the castor (10), and a positioning disk (35) with an inner thread (351). The shaft (30) is separated into a lower and an upper threaded segment (34) by a flange (33) resting on top of the insertion area (11) at the wheel (10). For lifting the corner of an object the disk (35) is rotated around the threaded segment (34) and the flange (33) is rotated in a second step to the required height. The disk (35) is lowered against the flange (33) in order to support the unit.</p> |
