Abstract
The movable partition system has a plurality of movable partition elements placed on a horizontal rail. Each of at least two of the movable partition elements has its own electric motor. Each electric motor has a current collector connected to it which passes along at least two conductor rails which are part of the electrical circuit when the electric motor is moved. These rails are connected via lines to a control unit which controls the power supply and the operation. One conductor rail is connected with a single line. On the other hand, at least one other conductor rail has a plurality of lines which lead to electrical connections or taps which are isolated from one another by insulators. This isolation permits the control unit to control the individual flow of current to each separate tap. This makes it possible to individually control and position the individual movable partition elements.
