Abstract
The shelving system has a number of electrically powered shelf units movable over ground, each shelf unit including an electronic circuit controlling the displacement of the shelf unit, a power cord connected to the shelf unit with of a power terminal rod, for feeding power to the shelf unit, and a network cable connected to the shelf unit with a network terminal rod, for allowing information to be exchanged with the electronic circuit. The shelving system further has a wire track that may be embedded in the ground, the wire track including an elongated main body having a hollow power wire channel housing the power cord and having an elongated opening allowing access to the power wire channel and forming an elongated power raceway allowing the power terminal rod to extend from the power wire channel to the shelf unit through the power raceway and to slide along the power raceway. The wire track main body further includes a hollow network wire channel housing the network cable and having an elongated opening allowing access to the network wire channel and forming an elongated network raceway allowing the network terminal rod to extend from the network wire channel to the shelf unit …
