The embodiment according to 4 is partly consistent with the embodiment described above, wherein similar or identical parts are provided with the same reference numerals, and to the explanation of which reference is also made to the description of the embodiment described above in order to avoid repetition.

A peculiarity of in 4 the embodiment shown is the slip-in strip ES ', which in 5 in perspective view and in 6 is shown in side view. The insert strip ES 'is opposite to in the 2 and 3 shown inserted longer, for kinked training about its longitudinal axis and / or formed multi-layered and is instead guided by two through three pairs of slots. In particular, the insertion strip ES 'is to be arranged alternately SPS1, SPS2 by the pair of slots formed by the slots S11, S31, the pair of slots formed by the slots S12, S32, and the pair of slots formed by the slots S13, S33.

The embodiment according to 7A and 7B partially coincides with the embodiments described above, wherein like or identical parts are provided with the same reference numerals, and to the explanation of which reference is also made to the description of the embodiments described above, in order to avoid repetition.

A special feature of the embodiment according to the 7A and 7B is the Einschiebedraht ES '''' trained insertion or mooring agent. 7B shows the insertion wire ES '''' in its actual form. The insertion wire ES "" centrally comprises a bracket B or projection. The bracket B is provided to be received by a slot LL.

As in 7A 1, the insertion wire ES "" is to be mutually arranged by the pair of slots formed by the slots S11, S31 and the pair of slots formed by the slots S12, S32. In 7A the insertion wire ES "" is shown schematically in a strongly curved shape and with an enlarged bracket B in order to better illustrate the passage through the slot pairs S11, S31 and S12, S32 and the slot LL. As further in 7A is shown, the slot LL is preferably similar or identical to the slot pairs described above. Again, a slot of the first longitudinal section 64 the first lateral surface 10 and a slot of the first longitudinal section 61 the second lateral surface 20 merged to form a pair of slots, which defines a passage opening or the slot LL for the bracket B. The bracket B is accommodated in the slot LL in order to prevent inadvertent slipping out of the insertion wire ES "" and to ensure a defined positioning of the insertion wire ES "". At the in 7A embodiment shown is the insertion wire ES '''' and in particular the bracket B disposed within the shell and thus does not protrude from the shell, neither laterally nor axially.

The table stand 1' is smaller than the floor stand 1 ,

A special feature of this embodiment is the mechanism for expanding the table top 1' which comprises at least two tabs L1 and L2 which are substantially opposite one another and / or overlap in sections, which are displaceable relative to one another in opposite directions and are acted upon by clamping elements SP1 and SP2, around the table stand 1' from a first state to a second state.

In the 9 shown tabs L3 and L4 are formed according to the tabs L1 and L2 and function accordingly, but are optional.

The tab L1 is at the first longitudinal section 64 the first lateral surface 10 preferably integrally formed or otherwise attached, while the tab L2 at the second longitudinal portion 60 the second lateral surface 20 preferably integrally formed or attached in other ways. Thus, the tab L1 is associated with the edge region RR2 of the shell, while the other tab L2 is associated with the other edge region RR1.

Like a comparison of 10 with the 13 and 14 shows, the two tabs L1 and L2 are displaceable relative to each other in opposite directions. In particular, the two tabs L1 and L2 and thus also the two spaced opposite edge regions RR1 and RR2 of the shell by means of the clamping elements SP1 and SP2 applied to each other towards the table stand 1' from the first state to the second state. In particular, the two tabs L1 and L2 are urged toward one another in a direction of application BR extending essentially transversely to the widening direction Q and are displaceable in the direction of application BR relative to one another.

As in particular in 13 and 14 can be seen, the two tabs L1 and L2 overlap at least with their free ends and are arranged parallel to each other, to avoid that the two tabs L1 and L2 block each other, for. B. when the table stand 1' from the first state to the second state. Further, as in particular in 14 can be seen, overlap the two tabs L1 and L2 at least in a cross-section of the shell substantially central region M of the shell. Furthermore, the clamping elements SP1 and SP2 extend at least in sections in the substantially central region M of the jacket. The clamping elements SP1, SP2 are preferably maximally tensioned in the first state.
