Fig. 3 shows a perspective schematic view of the frame element 20 of the levitation frame 1. A magnet unit 5 as shown in fig. 2 may be provided on the frame element 20.
The frame element 20 has a first side 21 and a second side 22 spaced apart therefrom in the longitudinal direction X; furthermore, the frame element 20 has a longitudinal portion 23 on one longitudinal side; in the present embodiment, the frame element 20 is in an open state on the longitudinal side opposite the longitudinal portion 23 in the transverse direction Y, since the magnet unit 5 of fig. 2 has the third and fourth securing members 13, 14, it is advantageous if the frame element 20 here has a second longitudinal portion 23 (not shown). When the magnet unit 5 is connected to the frame element 20, the frame element 20 is arranged around the entire circumference of the magnet unit 5, where the magnet unit 5 may be connected to the frame element 20 on each of the four sides. .
