Definitions

  • the invention relates to a height adjustable Work table with at least two support legs according to the preamble of claim 1.
  • desks including desks or Workbenches include, known, from a metallic frame exist, which carries the so-called worktop.
  • the frame initially consists of a base frame, which is made of at least two outer tubes connected at a distance via a strut which has a different cross-sectional shape and Can have cross-sectional size.
  • Inner tubes slidably guided, either exclusively over the worktop, but also additionally if necessary connected by a strut.
  • One outer tube each and an inner tube form a support leg of the work table.
  • a rope in the upper area of the outer tube connected which led to the lower end of the inner tube, diverted there, led up again and then in the upper one Area of the outer tube protrudes into the base frame and from there a traction unit, which is designed, for example, as a cable drum can be recorded.
  • a traction unit which is designed, for example, as a cable drum can be recorded.
  • the train unit Ropes of the support legs connected By moving accordingly the traction unit now becomes the inner tubes from the outer tubes gradually, but within given limits, pushed out, see above that the worktop is raised. With an opposite Movement of the traction unit, the traction ropes are released and the inner tubes move due to the weight, especially the worktop, back into the outer tubes.
  • the traction unit can either be manually or via a special one Drive.
  • Such a work table is now disadvantageous that if an inner tube jams in an outer tube and should jam with it, no lowering of the worktop is more possible.
  • An even greater disadvantage is considered that when the work table, for example, on the worktop the worktop should be grasped and carried up and move the inner tubes out of the outer tubes, until the maximum working height of the worktop is reached. In this height is mostly a carrying of the work table not possible anymore.
  • the invention is therefore based on the object Height-adjustable work table with at least two support legs To be designed so that the inner tubes are not in one hand can tilt and / or jam the outer tubes and at the on the other hand it is ensured that if, for example the worktop is raised to transport the worktable the position of the base frame will not change and thus the inner tubes in their position in the outer tubes remain.
  • a height-adjustable work table proposed that the train unit a counter train unit with at least two led out of the base and assigned to the pull ropes connected to the upper frame is.
  • FIG. 1 of the drawing is a detail shown, for example, work table 1 serving as a desk, the not shown, right area mirror image is formed to the drawn left area.
  • This Working table 1 initially consists of a base 2, which is formed from two outer tubes 3, of which only an outer tube 3 can be seen in the drawing.
  • This outer tube 3 is provided at its lower end with a base plate 4 which equipped with feet 5 for setting an exactly horizontal position is.
  • Both outer tubes 3 are in one via a strut 6 predetermined distance connected. This strut is 6 for better representation in their cross section or in their height drawn much larger.
  • Both outer tubes 3 take over, not shown, however known guides an inner tube 7 slidably. Both inner tubes 7 are fixed to one another via a worktop 8 connected.
  • the two inner tubes 7 and the worktop form 8 the so-called top frame of the work table 1, and each form an outer tube 3 and an inner tube 7 Support leg.
  • the inner tubes 7 in the outer tubes 3 have a deflection roller in their lower region 9 on, over which a pull rope 10 is guided.
  • This Pull rope 10 is at one end in the upper region of the base frame 2, for example in the upper area of the outer tube 3 attached at point 11.
  • the other end of the pull rope 10 is then via a deflection roller 12 from the outer tube 3 to the outside in guided the area of the strut 6 and there on a rope drum 13 attached, which forms the so-called train unit. That too Traction rope 10 of the support leg, not shown, is the same Way over pulleys 9, 12 and on the cable drum 13th attached.
  • the cable drum 13 is now, for example, electric Actuated drive 14 assigned via the traction cables 10 can be wound up. During this winding process the free length of the pull cables 10 is shortened, which leads to that the inner tubes 7 move out of the outer tubes 3 and thus the worktop 8 is raised. Lowering the Worktop 8 now takes place in such a way that the cable drum 13th is rotated in the opposite direction via the drive 14. The traction cables 10 unwind from the cable drum 13 and that consisting of the inner tubes 7 and the worktop 8 The top frame of work table 1 lowers through its own Weight off.
  • the inner tubes 7 can take place in the outer tubes 3 and be excluded, that the worktop 8 when, for example raised by hand to transport the work table 1 is able to move upwards relative to the base a so-called counter-pull unit is provided.
  • This consists of another, in the upper area of the inner tubes 7 at point 15 connected pull rope 16, which has a further pulley 17 is also guided into the area of the strut 6.
  • pull rope 16 of each support leg on another rope drum 18 attached.
  • This cable drum 18 has one for the traction cables 16 effective scope, which by half compared to effective scope of the cable drum 13 is reduced.
  • FIG. 2 of the drawing now shows an embodiment of the invention, which does not require a drive 14, but with a Drive 14 can be equipped.
  • the rope drum 18 an additional rope 19 associated with a pulley 20 out and attached to a fixed point 21 is.
  • a spring now engages on the axis 22 of the deflection roller 20 23, for example a gas spring, which corresponds to the weight of the top frame and the one by hand effortless lowering and lifting of the worktop 8 enables.
  • the spring 23 support the power of the drive 14. But is not a drive 14 provided, the cable drum 18 becomes a locking device 24 assigned.
