Definitions

  • the present invention relates to a device for adjusting the height and fixing the table top of a table, in particular office furniture.
  • the aim is to fix the table frame at the desired working height with as little play as possible by means of spindles and form-fitting guides.
  • the force for fastening the table frame is ideally non-positive, screws have to be loosened at several points, which makes easy assembly and height adjustment of the table frame difficult.
  • a piece of furniture with an adjustable table top with a front working side has also become known.
  • the table top is arranged between two side parts connected to one another by a rear, overhead support.
  • Protruding pins are anchored in the rear and side edges of the table top, each of which is detachably latched into one of several recesses arranged one above the other in the carrier and the side parts.
  • a protruding bolt which is mounted in the rear edge of the table top and moves back and forth, engages with its head under a vertical slot of the carrier, such that when the plate is disengaged for the purpose of adjusting it, it remains suspended in the carrier via the bolts.
  • the German utility model G 87 11 298 finally describes a work table with a height-adjustable table top, the table top being held by two side support arms, which are each arranged on a side foot.
  • the two support arms or support elements arranged in the feet are height-adjustable with a thread and crank.
  • the two support elements or support arms are open with a set screw on each side fixable at a certain height. This also results in the disadvantage of this worktable that a continuous height adjustment is not possible and a change in height is only possible by unscrewing and screwing in the mentioned adjusting screws.
  • the object of the present invention is, starting from the device according to the above German utility model, to provide a simple and robust device of this type which is practical to use and ensures absolute stability between the parts to be connected.
  • the table 1 to be described designed as office furniture, has three lateral table legs 2 and 3 with a rhombus-shaped cross section.
  • the table top 5 of the table 1 rests on a table frame 6 with two cross members 7.
  • the two table legs 2 and 3 have a cavity 8 which serves to accommodate two devices for height adjustment and fixing the table top 5. These devices are marked according to FIGS. 3 and 4 in the two table legs 2 and 3 with two crosses each. Two of these devices of a table leg 2 or 3 are held in a bearing plate 12 by means of screw spindles 13 and 14. These devices each comprise a transport plate 9, arranged in the cavity 8 of the table leg 2, and a clamping plate 10 located outside the leg 2.
  • the transport plate 9 is provided with an outer-center, continuous bore 16.
  • a side opening 17 in the plate 9 enables the insertion of a nut 18, which is inserted into the side opening 17 with a corresponding clearance with respect to the three-dimensional transport plate 9.
  • the nut 18 has a threaded bore which serves to receive the screw spindle 14.
  • the screw spindles 13 and 14 are rotatably held in the bearing plates 12, so that when they are rotated their transport plates 9 are correspondingly adjusted in height.
  • the mounting of the nut 18 with a large amount of play in the side opening 17 ensures a jam-free adjustment. This adjustment is carried out effortlessly by means of an Allen key 38, without any dismantling of table parts, through corresponding openings, for example in the table top 5.
  • the clamping plate 10 in turn has a passage 22 in its upper half and a bore 24 opposite the passage 21 in its lower part. This serves to receive a pin 25 which projects into the passage 21 of the transport plate 9, as shown in FIG. 5 shows. Due to the formation of the passage 21 in the transport plate 9, the clamping plate 9 can be pivoted about the pivot axis 26 by a few, e.g. 10 ° possible, so that the table top 5 can assume an inclined position in the desired frame.
  • the table frame 6, on which the table top 5 is mounted is attached to bearing arms 15, which in turn are firmly connected to the device.
  • the transport plate 9 and with it are adjusted in height.
  • a clamping device 27 with a horizontal bearing part 28 and a vertical bearing part 29 is used. These parts serve to accommodate an angular drive 30 with a horizontally mounted driven bevel gear 31 and a vertical drive bevel gear 32.
  • the bevel gear 31 points an extension in the form of a screw bolt 33, which, inserted through the passage 22, is screwed into the threaded bore 19 of the transport plate 9.
  • the bevel gear 32 in turn is provided with an Allen key socket 34, by means of the Allen key 38, without dismantling the table top 5, after adjusting the height and possibly tilting the table top, by turning the bevel gear 32, the bevel gear 31 with its screw bolt 33, the tensioning device 27 to the transport plate 9 moves there.
  • the inner wall of the table leg 2, 3 is sandwiched between the two plates 9 and 10, so that the table top 5 on the table frame 6, connected to the clamping device 27, is connected to the table legs 2 and 3 without play.
  • the clamping plate 10 is clamped via the clamping surface 36, which is roughened like a cord, for example.
  • the height adjustment and possibly inclination of the table top 5 is carried out as follows without any disassembly of parts:
  • the table top 5 should be lowered and tilted. Inserted into the socket 34 by means of the Allen key 38, the bevel gear 32 and with it the bevel gear 31 are rotated such that (FIG. 5) the screw bolt 33 is extended when the transport plate 9 is stationary and the clamping plate 10 is pushed to the right. As a result, the fixation between the clamping device 27 or the table top 5 and the table leg 2 is released.
  • the screw bolt 33 is screwed into the transport plate 9 by means of the Allen key 38 via the angle drive 30.
  • the clamping surface 36 presses the clamping plate 10 against the inner wall of the table level 2 until the fixing between the transport plate 9, the table leg 2 and the clamping plate 10 has been carried out without play.
  • a corresponding longitudinal groove is provided in the inside of the table leg 2, as can be seen in FIG. 5.
  • Each table leg 2 or 3 is provided for receiving two screw spindles 13 and 14 in the bearing plate 12, so that only three legs are required for two table tops 5 lying next to one another, the two table tops 5 being able to be adjusted individually and without impairing the secondary plate.
  • the table frame 6, support for the table top 5, is connected to the bearing arms 15, e.g. welded or screwed.
  • the two side box profiles of the table frame 6 are of different heights. The smaller profile leaves a passage between its top wall and the table top 5, which allows the insertion of cables for lighting, telephone, computer and other electrical connections without these cables disruptively occupying the table surface of the table top 5. Corresponding laying of these cables is also ensured by the cavities 8 of the table legs 2 and 3.
