Definitions

  • the invention relates to an actuating device according to the preamble of claim 1.
  • Such actuators for adjustable gas springs are e.g. used on office chairs in order to enable the relative movement of two chair parts to one another following the body movement of the user in a release position and, on the other hand, to be able to adjust a fixed position of the corresponding chair parts to one another in a locking position if desired.
  • the trigger plunger of the gas spring which is arranged in this longitudinally displaceable, must be able to be held in two different positions.
  • an operating lever that is on the trigger plunger acts and can be fixed in two different end positions by means of a link guide.
  • the object of the invention is to design an actuating device of the type in question in such a way that the actuating lever can be handled as simply as possible, which in particular should also be possible without visual inspection or coordination of the actuating process.
  • the device should enable a defined actuation and secure fixation of the end positions with a simple and inexpensive construction.
  • the ball provided according to the invention slides relatively smoothly from one end position to the other, ie from one recess of the actuating lever section to the other, but on the other hand it is ensured that an inadvertent adjustment is avoided by the formation of a pronounced dead center position between the end positions.
  • the design according to the invention enables handling, i.e. So the release of lockable gas springs, so that a so-called biofeedback takes place, so that the desired mechanical movement result largely coincides with the natural body movement, so that the internal resistance of the user against the mechanical handling that is initially foreign to him is as low as possible.
  • the configuration according to claim 2 ensures that the actuating lever can be easily mounted on the actuating device, but that no additional means for axially fixing the actuating lever are required, since this is accomplished in each of the end positions by the ball engaging in a recess acts as an axial lock.
  • the swivel angle limitation provided according to claim 3 ensures that the user finds the actuating lever in a defined end position and that only predetermined actuating movements are possible over the angular range between the two recesses, so that the user does not have to orientate himself about the angular position of the actuating lever.
  • the swivel angle limiting device is designed in a particularly simple and functionally extremely satisfactory manner.
  • the basic idea of this construction is therefore that a part of the second housing part which deviates from the round cross-sectional shape acts as a stop for the end of the actuating lever section which is flattened on one side. Accordingly the inventive circular chord-like limitation of the end of the cylinder bore or the end of the fastening lever section does not necessarily run exactly linear.
  • the measure according to claim 5 enables particularly simple manufacture and assembly of the second housing part.
  • the annular groove designed according to claim 6 enables the accommodation of a snap ring and thus in connection with a corresponding annular groove at the other end of the second housing part, the attachment of the same e.g. in an office chair,
  • Claims 7 and 8 indicate particularly simple possibilities for achieving an embodiment according to the invention.
  • Claim 9 specifies a particularly favorable embodiment of the connecting device between the housing of the actuating device and the piston of the gas spring, since this enables the actuation points to be optimally adjusted and this setting to be fixed during assembly.
  • Claim 1o indicates a preferred use of an actuating device according to the invention
  • FIG. 1 An office chair shown in FIG. 1 comprises a base frame 1 with a support column 2 which is connected to a seat support 4 receiving the upholstered seat 3.
  • a seat support 4 receiving the upholstered seat 3.
  • Fig. 1 only the lining 5 of the seat support 4 is shown.
  • the housing end of a gas spring lo has an annular sleeve 11 which is penetrated by a bolt 12 which is fixed in the side walls 13, 14 of the backrest support part 7.
  • the free end 16 is provided with an external thread 17.
  • An actuating device 18 has a first and a second housing part 19 or 20, which are each cylindrical.
  • the first housing part 19 is provided with an internal thread 21, into which the external thread 17 of the piston rod 15 is screwed.
  • the second housing part 2o is provided with an inner cylinder bore 22, in which a section 23 of an actuating lever 24 is guided.
  • the actuating lever section 23 has two recesses 25 and 25 'of different depths t 1 and t 2 .
  • End parts 28, 29 are screwed onto the two end faces 26, 27 of the second housing part 2o, each with the formation of annular grooves 3 0 , 31.
  • One end part 29 is compressed from the outside in the direction of arrow 32 in such a way that, as can be seen in particular from FIG. 5, the originally circular cross section is reduced with the formation of a chord 33.
  • the corresponding end 34 of the actuating lever section 23 has an outwardly open recess 35 such that between the chord 36 delimiting this recess 35 and the chord 33 there is an intermediate space a which pivots the actuating lever section 23 by approximately 90 ° ° enables, but on the other hand also a swivel angle limitation is achieved in that when twisting from the in Fig.
  • An axially movable trigger plunger 37 is arranged at the lower end 16 of the piston 15. Between the lower end of the trigger plunger 37 and the operating lever section 23, a ball 38 is arranged such that it is in contact with the trigger plunger 37 on the one hand and with the operating lever section 23 on the other hand.
  • the ball 38 Since the ball 38 is fixed by the housing part 19 in the axial direction with respect to the longitudinal axis of the second housing part 20 and is either pressed into the recess 25 or 25 'of the actuating lever section 23 by the release plunger 37, the ball acts as a bolt against axial displacement of the actuating lever (24) in the second housing section 2 0 , so that no additional locking devices have to be provided.
  • the actuating device 18 When the actuating device 18 is mounted on the gas spring, the latter is screwed to the piston 15 of the gas spring, the desired contact force of the actuating plunger 37 on the ball 38 being able to be set in this assembly process by means of a lock nut 4o.
