摘要

The carriage (24) from which protrudes a bar-shaped element (26) runs along the runner rail (22) by using the drive mechanism. The runner rail, on the side from which the bar-shaped element protrudes, is closed as far as a longitudinal gap (58) which just allows the bar-shaped element to pass through it. The runner rail on the side from which the bar-shaped element protrudes is open and is closed by subsequently placed covers (54,56) as far as the gap. The outer ends of the U-sectioned profile (42) of the runner rail has inward-projecting arms (50,52) ending at a distance (A) from one another.
