    • figure 3 shows the folding table of figure 2 with the legs folded down;
    • figure 4.1 and 4.2 show in detail the brackets of the height adjustment means; and
    • figure 5 shows further clarifying details of the height adjustment means.
  • Whenever in the figures the same reference numerals are applied, these numerals refer to the same parts.
  • With reference first to figure 1 a folding table 1 according to the invention is shown, comprising a tabletop 2 and table legs 3, 4. The table legs 3, 4 are movable between a folded down position which is shown in figure 3, and an unfolded position which is shown in figure 1 and in which the table is ready to use. The folding table 1 of the invention is embodied such that the tabletop 2 has an adjustable height position, which provides a challenge in design considering that in the unfolded position as shown in figure 1 the table legs 3, 4 extend essentially perpendicular from the tabletop 2.
  • The design challenge is met by arranging that the tabletop 2 is provided with first height adjustment means 5, such as a screw axle, which can be either motor or hands driven. In the shown embodiment the first height adjustment means 5 are hand driven by providing a swing handle 6. This can however desirably be replaced by a motor drive.
  • In a manner that is known per se and which therefore does not require to be elucidated with reference to the drawing, the table legs 3, 4 are provided with second height adjustment means. Usually the second height adjustment means are embodied as a spindle. According to the invention the first height adjustment means 5 that are provided on the tabletop 2 are arranged to be releasably connectable with the second height adjustment means that are provided in the table legs 3, 4. This provides the advantage that when the table is folded down, both the first height adjustment means 5 on the tabletop 2 and the second adjustment means in the table legs 3, 4 can remain in place without hindering the transition of the folding table 1 between its erect position and its folded down position.
  • The folding table 1 of the invention is preferably so construed that the first height adjustment means 5 extent into a first bracket 7 and the second height adjustment means extend into a second bracket 8, wherein the first bracket 7 and the second bracket 8 are connectable by positioning the table legs 3, 4 in the unfolded or erect position wherein the table is ready to use.
