Definitions

  • the invention relates to a table comprising round extendable table legs for supporting a tabletop, comprising telescopically extendable tubes with a circular cross-section, which tubes fit into each other and which tubes comprise in their interior a spindle construction for displacing the tubes with reference to each other for placement of the tabletop at a desired height, wherein the table legs further comprise a ground-base that extends at right angles with respect to the telescopically extendable tubes.
  • Such a table with round extendable table legs with a circular cross-section is well known.
  • the legs do not have a circular cross-section but a rectangular cross-section.
  • the table with round extendable table legs with a circular cross-section is disadvantageous in comparison with the table provided with extendable table legs with a rectangular cross-section in that it requires specific measures to be taken to prevent that the ground base of the table can be rotated with reference to the tabletop.
  • This has the disadvantage that it increases the costs of manufacturing of such tables with round extendable table legs, which are therefore appreciably cost-lier than tables provided with extendable table legs having a rectangular cross-section.
  • each table leg comprises telescopically extendable tubes with a circular cross-section, which tubes fit into each other and comprise in their interior a spindle construction for displacing the tubes with the circular cross-section with reference to each other for placement of the tabletop at a desired height.
  • the table legs further comprise a ground-base that extends at right angles with respect to the telescopically extendable tubes, wherein the spindle construction provided within the telescopically extendable tubes with a circular cross-section comprises at least one tube with a rectangular cross-section placed in the interior of the telescopically extendable tubes with the circular cross-section.
  • CN 203 168 365 a highest tube with a circular cross-section is rotationally fixed to the tabletop, and the lowest tubes with a circular cross-section are mutually connected with a separate sidebar that extends between the legs.
  • the table of the invention comprising round extendable table legs has the feature that the spindle construction comprises plural telescopically extendable tubes with a rectangular cross-section, wherein the highest tube of the telescopically extendable tubes with the circular cross-section is rotationally fixed with a connection to at least one of the telescopically extendable tubes with the rectangular cross-section, and wherein a lowest tube with the rectangular cross-section is rotationally fixed to the ground-base.
  • a lowest tube with a circular cross-section is also rotationally fixed to the ground-base.
  • an engagement piece or pieces are provided that have a rectangularly shaped side that engages the tube of the telescopically extendable tubes with the rectangular cross-section, and that has a circularly shaped side opposite to the rectangularly shaped side, which circularly shaped side engages and connects to respective tubes of the telescopically extendable tubes with the circular cross-section.
  • the engagement piece or pieces are applied in two types, a first type engagement piece that enables sliding along the telescopically extendable tube with the rectangular cross-section, and a second type engagement piece which is disabled to slide along the telescopically extendable tube with the rectangular cross-section.
  • a series of longitudinally extendable tubes can be applied to move concertedly between a fully retracted and a fully extended position.
  • the first type engagement piece that enables sliding along the telescopically extendable tube with the rectangular cross-section is connected to a highest telescopically extendable tube with a circular cross-section.
  • the second type engagement piece which is disabled to slide along the telescopically extendable tube with the rectangular cross-section is provided with a protrusion that cooperates with an aperture in the telescopically extendable tube with the rectangular cross-section.
  • figure 1 shows a table 1 which is provided with round extendable table legs 2 according to the invention.
  • the table leg 2 of the table 1 of the invention comprises telescopically extendable tubes 6, 7, 8 with a circular cross-section, which tubes 6, 7, 8 fit into each other and which tubes 6, 7, 8 comprise in their interior a spindle construction for extending and retracting the tubes 6, 7, 8 with reference to each other for placement of the tabletop 1' at a desired height.
  • the spindle construction will in as far as necessary hereinafter be further explained with reference to figure 2 , it being noted that the spindle construction as such is well known from the prior art and requires therefore no further elucidation. Before doing so, reference is first again made to figure 1 which shows that the table leg 2 further comprises a ground-base 5 that extends at right angles with respect to the telescopically extendable tubes 6, 7, 8.
  • the spindle construction 4 that is provided within the telescopically extendable tubes 6, 7, 8 with a circular cross-section, comprises telescopically extendable tubes 12, 13 with a rectangular cross-section.
  • the highest tube 7 of the telescopically extendable tubes 6, 7 with the circular cross-section is rotationally fixed with a connection to at least one of the telescopically extendable tubes 12, 13 with the rectangular cross-section, and a lowest tube 13 with the rectangular cross-section is rotationally fixed to the ground-base 5. Rotation of the lowest tube 13 with the rectangular cross-section and of the lowest tube 8 with the circular cross-section is thus prevented.
  • a lowest tube 8 with a circular cross-section is also rotationally fixed to the ground-base 5.
  • the spindle construction 4 with the telescopically extendable tubes 12, 13 with the rectangular cross-section are placed in the interior of the telescopically extendable tubes 6, 7, 8 with the circular cross-section.
  • the telescopically extendable tubes 6, 7 with the circular cross-section are rotationally fixed with a further connection 3, 14 to the telescopically extendable tubes 12, 13 with the rectangular cross-section.
  • an engagement piece or pieces 3, 14 are provided that serve as a rotationally fixed connection between the tubes 6, 7 with the circular cross-section and the tube 12 with the rectangular cross-section. This is accomplished by arranging that the engagement piece or pieces 3, 14 have a rectangularly shaped side 3', 14' (see figures 3 and 4 ) that engages the tube 12 with the rectangular cross-section.
  • these engagement pieces 3, 14 have a circularly shaped side 3", 14'' opposite to the rectangularly shaped side 3', 14', which circularly shaped side 3", 14" engages and also connects to the respective tubes 6, 7 of the telescopically extendable tubes with the circular cross-section.
  • Figure 3 and figure 4 further depict that the engagement piece or pieces 3, 14 are applied in two types, a first type engagement piece 14 which is shown in figure 3 that enables sliding along the telescopically extendable tube 12 with the rectangular cross-section, and a second type engagement piece 3 which is shown in figure 4 and that is disabled to slide along the telescopically extendable tube 12 with the rectangular cross-section and fixed to a lower part of the tube 12.
  • Figure 4 shows further that the second type engagement piece 3 which is disabled to slide along the telescopically extendable tube 12 with the rectangular cross-section is for that purpose provided with a protrusion 3"' that cooperates with a corresponding aperture (not shown) in the telescopically extendable tube 12 with the rectangular cross-section.
  • Figure 2 finally shows that the first type engagement piece 14 that enables sliding along the telescopically extendable tube 12 with the rectangular cross-section is connected to a highest telescopically extendable tube 7 with a circular cross-section.
  • the second type engagement piece 3 that cannot slide along the telescopically extendable tube 12 and that is connected to a lower part of this tube 12, is further connected to a telescopically extendable tube 6 with a circular cross-section which is below the highest telescopically extendable tube 7 with a circular cross-section.
