Definitions

  • the invention relates to a base with a support column for work chairs, such as swivel chairs and others, which is designed with multiple arms, and the arms of which are directed radially and cantilevered outwards from a holder in the center, and the support column is held on a holder in the center of the base and from this is cantilevered to the seat of the work chair, this support column, in particular telescopic and allows rotation of at least one of its parts about its longitudinal central axis.
  • the invention has for its object to provide a work chair for high-lying workplaces that climbed easily regardless of the height of the seat and footrests at any desired height to this seat, as well as the seat itself optimally adjusted in the direction of rotation to the workplace can be.
  • a star base of the type mentioned in that the arms have downward bends in the region of their free ends, and these bends at a predetermined height of the freely projecting part of each arm at least one height locking means for has steps to be hooked in between the arms, and that in the area of the support of the support column the base is provided with a rotation lock for this column.
  • the base 1 is essentially formed by a plurality of arms 2-6 directed outwards in the form of a beam, each of which has a downward bend 8 in the region of its freely projecting end 7, so that a further part 9 of the arm is formed from this bend remains downward.
  • the part 9 of this arm 2-6 can have a certain height H, a height which can be aligned according to the height of the implement to be reached later.
  • 2-6 steps 12 at different heights can be provided between the individual parts 9 of the respective arm, these steps have at their freely projecting ends locking cams 13, for which 2 - 6 slots are provided on the parts 9 of the arms for locking them.
  • Each part 9 of the respective arm 2-6 can have slots arranged at different heights so that the respective steps 12 can also be clicked in at different heights between the freely projecting ends 7 of these arms.
  • Such a design of the individual slots and thus locking options on the parts 9 of the arms 2-6 allows an individual arrangement of the individual steps 12, so that, seen at an angle of rotation, between two arms, for example 2, 3, the one step 12 entirely below, another one in the middle and a third one could be snapped in at the top if necessary.
  • the step frame could have step-like, height-offset steps 12, which makes it very easy to climb the seat surface 10.
  • the design of the locking means 13 as slots and locking cams has the advantage that the treads 12 can be adjusted differently in height by simply lifting them out of the anchors.
  • a holder 14 together with the direction of rotation 15 for the support column is provided in the area of the central connection of the arms 2-6.
  • the rotation lock 15 is formed by a bearing block 16, a clamping jaw 18 and an axial guide 17 lying between them.
  • the Bearing block 16 is firmly anchored on the holder 14 or on the part of the support column 11 held non-rotatably by this holder, while the clamping jaws 18 above it are rotatably guided on the telescopic part of the support column.
  • the axial guide 17, which can be designed as a sheet metal strip for the sake of simplicity, is suspended at one end on the clamping jaws 18 and guided axially at the other end in runners 19 of the bearing block 16.
  • the length of this axial guide is such that it corresponds approximately to the stroke of the support column 11.
  • a spring can optionally be provided between the bearing block 16 and the clamping jaws 18 in order to keep these parts at a certain distance from one another.
  • the sheet metal strip or the axial guide 17 can also be provided at its freely projecting end with a safeguard against inadvertent pulling out of the sheet metal strip from the runners 19 of the bearing block 16. It is advisable to provide this locking device in order to release the anti-rotation lock 15, i.e. when the clamping jaws 18 are lifted when the support column 11 is extended. their bearing block 16 from the jaws 18 to exclude.
  • At least the jaws 18 can be U-shaped, the legs of which can be tightened or loosened by means of a screw clamp 21.
  • the anti-rotation device 15 can be fitted over a hood 20 covering its parts.
  • the sheet metal strip of the axial guide 17 is provided laterally on the bearing block 16 and clamping jaws 18. However, it should be recommendable to provide this in the curved section of the bearing block 16 and the jaws 18.
