Ceiling track system for guiding wall elements

A ceiling track system comprising:

• a guiding rail having a latching geometry;
• at least one wall element is received in the guiding rail via a carriage unit;
• at least one encasing element, configured as a profile in an L-shape having one long and one short leg, is affixed to the guiding rail, wherein the long leg extends in a vertical joining direction;
• a latching hook disposed at the long leg configured to be latched to the latching geometry to affix the encasing element to the guiding rail from a unidirectional joining direction in a self-retaining manner;
• a geometric transition, between the long leg of the encasing element and the latching hook, has a cross-sectional constriction;
• a web with a projection arranged at the long leg adjacent to the area of the cross-sectional constriction;
• a groove in the guiding rail, into which the projection engages for the self-retaining purpose of the encasing element at the guiding rail;
• a screw reception in the guiding rail adjacent to the groove;
• and
• a screw element is screwable into the screw reception, wherein a clamping action of the web at the guiding rail is achieved;
• wherein the screw reception is configured at an angle with regard to the vertical joining direction, to screw in the screw element from the direction of a plane of symmetry of the guiding rail.
