the supporting frame 5 this figure further shows the telescopic extension 19 between neighboring step elements 2 the guidance in the telescopic extensions 19 prevents tilting of the step elements 2 such that not every step element 2 must be supported on the floor 6 by supporting elements 11 13 fig1 shows a side view of a podium 1 having the particular feature that it is formed of two mutually parallel supporting frames 5 5 a disposed at a separation with respect to one another and with their upper edge at different heights the two supporting frames 5 5 a not only have different heights but also have different bases the front supporting frame 5 a is on the floor 6 whereas the rear higher supporting frame 5 is located on a base scaffolding the base scaffolding can e g be a platform another embodiment of a suitable base scaffolding may be a carriage chassis or a semitrailer 20 by means of which the supporting frame 5 can be transported with inserted step elements 2 for static reasons lateral extensions 21 can be provided on the base scaffolding or the semitrailer 20 for support the podium 1 is formed by the two adjacent supporting frames 5 5 a wherein in the embodiment shown the step elements 2 are not lifted and extended out of the front supporting frame 5 a when the rear supporting frame 5 is located at a larger height or its front step elements 2 are only partially extended the rear stack 4 of the front supporting frame 5 a can also be used fig1 shows in partial section details of the telescopic extension 19 and of the connecting elements 22 laterally erected on the step elements 2 the connecting.
