Definitions

  • the invention relates to a table comprising a central portion, at least one wing portion and a plurality of legs.
  • each leg of a table of the above described type is provided with a height adjustment mechanism, the mechanisms being in interconnected relationship, each mechanism comprising a worm-worm wheel transmission, located at the respective leg, the worms being interconnected through universal joints and detachable connecting rods with telescopically resilient portions.
  • connection between the wing portion and the central portion can extend according to a curved line of separation and the portions can be interconnected by a tie member.
  • a curved line of separation Adjacent said line of separation, the central portion and the wing portion may each be provided with a groove, in which grooves there is provided a connecting strip.
  • German patent 64,229 discloses per se a table comprising legs fitted with height adjustment mechanisms, said legs being adjustable in height entirely or partly by means of one operating mechanism. For this purpose, the drive spindle is moved in axial direction.
  • the construction described relates to the lifting and lowering or inclination of a table top, in this case a drawing-board.
  • a table comprising a central portion and at least one wing portion.
  • US patent 3,741,852 describing a table comprising various parts, and forms, respectively. However, this concerns each time separate tables, each having fixed legs and being loosely positioned in juxtaposed relationship when in use.
  • each leg may consist of at least two telescopically coacting portions.
  • a leg adjustment mechanism comprises an attachment plate 1 to which a depending jacket 2 is attached in a manner not shown, and a casing 3 for a worm-worm wheel transmission.
  • a worm 4 is fitted towards both ends with a worm stub shaft 5, to which a universal joint portion 6 is attached.
  • a worm wheel 7 secured against rotation is mounted on a threaded shaft 8.
  • This threaded shaft is received in a nut 9, which is affixed to the top of a support 10 fitted with a foot 11.
  • the jacket 2 is fitted with a slot 12, receiving a pin 13 affixed to the support 10.
  • the edge of the slot may be fitted with a dimensioning, not further shown.
  • the universal joint portion 6 connects to a corresponding universal joint portion 14, the free end of which is fitted with a cross-sectionally square pin 15. Said pin 15 is slidingly received in a corresponding recess of a connecting rod 16. Between the universal joint portion 15 and the connecting rod 16, there is provided a compression spring 17.
  • FIG. 3 diagrammatically shows as central portion 18 and wings 19 linking up therewith by means of a curved line of separation 30.
  • the wings 19 instead of the wings 19, use can also be made of the wing 34 shown at the right in Fig. 3.
  • wings of different formats or sections, or a plurality of wings one behind the other are possible.
  • each leg adjustment mechanism 1-10 Underneath each wing, there is represented a leg adjustment mechanism 1-10 with a foot 11. As shown in the drawings, the leg adjustment mechanisms are interconnected by means of the worm stub shafts 5, the universal joint portions 6, 14 and the connecting rods 15. The central axes of the worm shafts and the connecting rods may be at an angle relative to each other different from 180°.
  • leg adjustment mechanism mounted underneath the wing 34 is fitted at the projecting free universal joint portion 6 with a detachable or non-detachable crank 23 adapted to adjust the coupled leg adjustment mechanisms.
  • a deflection thereof it is possible, as shown in dotted lines in Fig. 1, to provide a cross-sectionally rectangular tube 35 having lugs 36, the central axis of which extends through the pivot point of the universal joint 6, 14.
  • the lugs 36 are rotatably connected, by elements not shown to the attachment plate 1, and a support 37 attached to the jacket 2, respectively.
  • FIG. 4 shows the attachment of the attachment plate 1 to the wing 19.
  • the wing 19 is fitted with a bore 20 having edge holes 21.
  • an internally threaded bush 22 In said bore and one of the edge holes, there is received an internally threaded bush 22.
  • a screw 23 extending through an opening in the attachment plate 1 is adapted to coact with the bush.
  • FIG. 5 finally shows the attachment of the central portion 18 to the wing 19.
  • a hole not further shown, wherein there is arranged both an internally and an externally threaded bush 24.
  • the bush 24 coacts with a screwed spindle 25, the projecting end of which extends through a recess 26 in the central portion 18.
  • the screwed spindle 25 extends through the recess 26 into a recess 27 and is fitted at that location with a washer 28 and a nut 29. By tightening the nut 29, the wing is firmly pulled against the central portion 18.
  • both the central portion 18 and the wing 19, at the line of separation 30, is fitted with a recess 31, 32, wherein a connecting strip 33 is received.
  • the table according to the invention is particularly suitable among other things for placing thereon a computer-like terminal, while the terminal itself can be arranged on the central portion and auxiliary appliances, if any, and forms, respectively, can be disposed on the wing(s).
