Definitions

  • the innovation concerns a work table with an adjustable table top on two support arms on a frame with two vertical, legged tubes that are connected to each other by a crossbar.
  • the proposed work table is used in particular in offices which are equipped with data processing devices, in particular with keyboards and screens.
  • work tables are often equipped with adjustable table tops so that they can be adapted to the height of the operator, taking into account the appropriate arm position and advantageous viewing height.
  • the task of the innovation consists in the design of an adjustment mechanism for the table top of a work table, which is housed completely inside the frame supporting the table top and thus removed from the eye.
  • a work table with an adjustable table top on two support arms on a frame with two vertical, legged tubes, which are connected by a crossbar is assumed and the object is achieved in that the tubes have longitudinal slots that a vertically displaceable and adjustable support element is provided in each tube, and that the support arms are fastened to the support elements in a manner penetrating the longitudinal slots.
  • the proposed support elements accommodated in the tubes a height adjustment in steps or continuously of the table top is possible, which is practically invisible from the outside.
  • the tubes and the support elements expediently have a square cross section.
  • the support elements can be fixed to the tubes with at least one set screw passing through the tubes.
  • threaded spindles are provided in the tubes, on which the support elements provided with an internal thread can be displaced.
  • the threaded spindles are advantageously rotatably mounted in pedestals, which sit in the tubes near the feet.
  • At least one gear acts on the connecting shaft, with the aid of which it can be rotated either by hand or by an electric motor.
  • a longitudinal toothing can alternatively be attached to one of the two threaded spindles, in which a worm wheel engages, which is fastened on a drive shaft mounted in the foot.
  • the support arms are pivotally attached to the support elements.
  • Each support element expediently carries a longitudinal web which engages in a groove of the support arm and which has two eyes has, in one of which the support arm is articulated and on the other of which a fork is pivotally attached, on which a threaded bushing is formed, into which an actuating shaft mounted in the support arm engages with a terminal thread.
  • the table top is tilted by turning the actuating shaft.
  • an aperture is expediently provided on the support element, which is behind the longitudinal slots.
  • the work table shown in the drawings consists essentially of a table top 1, two support arms 2, two tubes 3, two feet 4 and a crossbar 5.
  • the two tubes 3, the two feet 4, and the crossbar 5 are connected to one another and form together a rack.
  • the rectangular table top 1 (FIG. 1), which is made of coated wood, for example, is adjustable according to the two arrows a and b with respect to its height (in steps or continuously) and its inclination (continuously) within certain limits.
  • the two parallel, made of wood or metal support arms 2 are attached.
  • the two metal feet 4 (Figure 1) are attached at right angles to the lower ends of the tubes 3 and they are parallel to each other.
  • the two tubes 3 are made of seamless drawn steel and they have a square cross section.
  • the feet 4 are welded or screwed to the pipes.
  • the two tubes 3 have longitudinal slots 6 pointing in the region of their upper ends in the direction of the support arms 2 (see FIG. 2), and a support element 7 made of metal or plastic fits appropriately in each tube 3 approximately at the level of the longitudinal slots 6.
  • threaded spindles 8 are provided centrally in the tubes 3, which are rotatably mounted in bearing blocks 9, which are seated in the tubes 3 and near the feet 4.
  • the supporting elements 2 provided with corresponding internal threads 10, which can be displaced and locked with the aid of these threaded spindles 8.
  • the support elements 2 ( Figure 4) have a prismatic shape with a square cross section.
  • Each support element 2 carries an essentially prismatic longitudinal web 11 which is screwed to the support element 2 with fastening screws 12.
  • the support arms 2 are pivotally attached to the support elements 7 through the longitudinal slots 6 via these longitudinal webs 11, in this case the longitudinal webs 11 engage in a groove 13 in the support arms 2.
  • Each longitudinal web 11 carries two eyes 14 and 15.
  • the respective support arm 2 is articulated on the lower eye 15 with a bolt 16 (see FIG. 2), and a fork 17 with a socket pin 18 is pivotally suspended on the upper eye 14.
  • a threaded bushing 19 is formed on this fork 17, into which an actuating threshold 20, which is rotatably mounted in the support arm 2, engages with a terminal thread 21.
  • the table top 1 is inclined. It would also be conceivable that the table top 1 is articulated at the free end of the support arms 2.
  • the easiest way to adjust the height of the table top 1 in stages is to provide holes in the tubes 3 at the side through which a set screw 23 is screwed into one of several threaded holes 24 which are in the support element 7 are arranged at different heights.
  • a stepless height adjustment of the table top 1 is done by rotating the two threaded spindles 8 together.
  • each threaded spindle 8 carries a bevel gear 25 on the head side and above the supporting element 7.
  • a connecting rotary shaft 26 is mounted in the crossmember 5, at the two ends of which end bevel gears 27 are seated that are engaged with the bevel gears 25.
  • Small gears 28 are provided on the connecting rotary shaft 26 (FIG. 1), which essentially consist of a bevel gear seated on the connecting rotary shaft 26 and a vertically arranged shaft stub with counter bevel gear, which sit in a housing.
  • a hand crank 29 can be inserted into an internal hexagon of the shaft stump, with the aid of which the connecting rotary shaft 26 and thus the two threaded spindles 8 can be set in rotation via the relevant gear 28.
  • the rotation of the threaded spindles 8 causes the support elements 7 and thus the table top 1 to be raised or lowered continuously.
  • the transmission 28 can also be provided with an electric motor drive.
  • An alternative possibility of actuating the threaded spindles 8 is that one of them has a longitudinal toothing 30 on its circumference (indicated in FIG. 2).
  • the longitudinal toothing 30, which corresponds to the length of the longitudinal slot, could also be provided in the area of the longitudinal slot 6 and the drive shaft 32 of the worm wheel could be mounted in the support arm 2.
  • the worm wheel 31 itself would then find its place inside a hollow support element 7 (not shown).
