Abstract: The sliding device for a sliding panel comprises:a) a support which is shaped in or attached to the bottom portion of the panel, said support having a downwardly open upside-down U-shape;b) an oscillating arm secured to the support about a pivot axis which is horizontal and which extends transversely relative to the U-shape;c) sliding means fixed towards the free end of the oscillating arm;d) a pivoting cam which is secured to the support by a first axis of rotation and bears against the oscillating arm; ande) an adjustment screw which is fixed relative to the support and whose displacement serves to adjust the angle of rotation of the cam by means of a linkage between the cam and the adjustment screw.It may also include means for locking the oscillating arm in position relative to the support whenever the sliding means is in its high position within the support.

Abstract: The covering section bar has a generally U-shaped inner housing defined by two side branches and a cross-bar, the first side branch having a fastening or snap-fastening shoulder and being elastically deformable at a first level of deformation, being of a thickness that is less than the mean thickness of the section bar, at least in the zone thereof where elastic deformation is required; the inner housing includes a first bearing zone corresponding to the fastening shoulder or situated close to the snap-fastening shoulder, a second bearing zone situated on the same side of the inner housing, and a third bearing zone situated on the second side branch and located in between the two first-mentioned bearing zones. The section bar covers either a panel or a panel-fastening section bar, after one or other of them has been inserted in its inner housing. The combination of the covering section bar and of the fastening section bar constitutes a panel frame element.
