Telescopic rail

A telescopic rail (4) comprising

• a first rail element (1),
• a second rail element (2),
• a third rail element (3), and
• a drive device (13);
• wherein the first rail element (1) and the second rail element (2) are mounted together such that the first rail element (1) and the second rail element (2) are linearly displaceable relative to one another in and counter to a pull-out direction (7);
• wherein the third rail element (3) and the second rail element (2) are mounted together such that the third rail element (3) and the second rail element (2) are linearly displaceable relative to one another in and counter to the pull-out direction (7);
• wherein the drive device (13) is mounted on the first rail element (1) or is mountable on a holding element connectable to the first rail element;
• wherein the drive device (13) is configured such that, in an operation of the telescopic rail (4), the drive device (13) causes a linear movement of the second rail element (2) relative to the first rail element (1) in or counter to the pull-out direction (7);
• wherein the telescopic rail (4) comprises a traction element (5);
• wherein the traction element (5) is fixed to the first rail element (1) and to the third rail element (3);
• wherein the traction element (5) is guided on the second rail element (2) in a direction parallel to the pull-out direction (7) such that a displacement movement of the second rail element (2) relative to the first rail element (1) leads to a displacement movement of the third rail element (3) relative to the second rail element (2);
• and
• the drive device is selected from a spindle drive, a tooth belt drive, a rack-and-pinion drive, a flexible shaft, a push rod, a push element, a traction element, a cable pull, a gas compression spring, a hydraulic or pneumatic cylinder, a receptacle for a linear motor, an electromagnetic linear drive, or a combination thereof.
