Definitions

  • the present invention relates to a height-adjustable column, in particular for tables.
  • Height adjustment of a table such as an office desk is one of the basic ergonomic requirements for office furniture system manufacturers today.
  • Table legs in the form of guide columns and / or complete table bases make it possible to customize tables to each user.
  • Such height-adjustable columns are known to consist of an inner column, a center column and an outer column, which are moved into each other or pulled apart, whereby the height can be adjusted.
  • the height adjustment can be done by a lifting mechanism that can be done manually as well as power-assisted as well as purely electrically.
  • these requirements are only partially met by the previously known solution concepts. crowded. In the known solutions, either the required heights are not achieved or the optical requirements are not met, since, for example, the drive for the lifting mechanism is usually mounted transversely to the stroke direction outside the actual pillar installation space.
  • Cross-section have a large compared to the basic height stroke, the stroke of the columns should be approximately as large or larger than the basic height of the column. It should be ensured that even small persons at such a Working table while sitting, and that even with tall people for a standing working position a sufficient table height can be achieved.
  • a height-adjustable column which has an inner column, a center column and an outer column.
  • a double translating lifting mechanism together with a linear drive ensures that the height adjustment of the individual column elements runs synchronously.
  • the stroke of the columns is actually as large or larger than the basic height of the column.
  • the linear drive is dimensioned and arranged so that it protrudes beyond a bottom of the outer column in the inserted state.
  • the linear drive can be introduced down into the space of a foot attached to the height-adjustable column.
  • the foot in this case has a cavity which is open via an opening to the height-adjustable column, so that the linear drive can protrude in the inserted state into the cavity of the foot.
  • the linear drive is preferably performed in a receptacle which is provided on the underside of the center column, wherein the linear drive can be supported on the receptacle.
  • the linear drive preferably consists of a drive motor, a driven by the drive motor threaded spindle and a rotatably provided in the recording spindle nut, on which the threaded spindle moves during rotation.
  • the drive motor is connected to the inner column, so that upon rotation of the threaded spindle of the drive motor together with the threaded spindle displaces the inner column, since the threaded spindle on the spindle nut, which is provided in the attached to the central column receptacle supported. As a result, a height adjustment of the inner column can be effected.
  • the linear drive can also consist of a piston rod and a gas spring, or from any other type of drive, which allows a linear adjustment exist.
  • the receptacle for the linear drive preferably also protrudes beyond the underside of the outer column into the opening of the foot.
  • An attachment between the receptacle and the foot can also be advantageously provided.
  • the lifting mechanism is preferably made of a thrust plate which is fixed to the center column and at the bottom and top of each has pulleys over which a steel cable or a band is guided.
  • the steel cable or band is attached in each case via a strand on the one hand to the inner column and on the other hand to a support rod of the outer column.
  • FIG. 1 shows a longitudinal section of a height-adjustable
  • Figure 2 shows a longitudinal section of the height-adjustable column in the inserted state.
  • FIG. 3 shows a cross-sectional view according to the section lines A-A from FIG. 2.
  • the height-adjustable column consists of an inner column 1, a center column 2 and an outer column 3.
  • the inner column 1 has an upper side Ic in the form of a cover plate.
  • the inner column 1 is open at the bottom and hollow inside.
  • the center column 2 is open at the top and largely hollow inside. It has on its underside 2a a cover plate.
  • a support tube 7 is provided with an upper end 7a and a lower end 7b in the center pillar.
  • the support tube 7 has a circular cross-section. As can be seen from FIGS.
  • the support tube 7 protrudes downwards beyond a recess in the center pillar 2, so that the lower end 7b projects beyond the end of the center pillar, that is to say the underside 2a of the center pillar 2.
  • the length of the support tube 7 is approximately two-thirds of the length of the center column. The length depends mainly on the dimensions of a later described drive motor 4, in particular of its axial length dimension. The total length of the drive motor together with the support tube located within the center column is the total length of Center column.
  • the center column 2 corresponds in length approximately to the length of the inner column. 1
  • the outer column 3 is hollow and open at the top. At its bottom 3a it is closed by a cover. However, this cover has a recess 3b.
  • a support bar 16 is provided on the underside 3a, which, as can be seen from Figure 3, has an I-profile.
  • the support rod 16 projects straight up and has a length which corresponds approximately to the length of the outer column 3.
  • an outer column-side attachment 15 is provided at the upper end of the support rod 16. This connects the support rod 16 with a later to be described lifting mechanism 21st
  • the linear drive 22 will be described in more detail below with reference to FIGS. 1 and 2.
  • the linear drive consists of an electric drive motor 4 from which protrudes a threaded spindle 5, which can be rotated via the drive motor.
  • the drive motor 4 is fixed to the inside of the top Ic of the inner column 1.
  • a spindle nut 6 is provided, which is rotatably connected to the support tube 7.
  • the spindle nut has an internal thread into which the threaded spindle 5 can be screwed.
  • the pitch of the threaded spindle and the spindle nut are preferably designed so that a self-locking of the threaded spindle relative to the spindle nut in each adjustment position is possible, so that no extra braking device must be provided for the drive and the threaded spindle is fixed in the respective position when the electric Drive is switched off.
  • a piston rod can be combined with a gas spring, in which case, however, a braking device must be provided.
  • the lifting mechanism 21 consists essentially of a thrust plate 8, two pairs of guide rollers 10 and 11 respectively at the upper and lower end of the thrust plate, which are rotatably supported via respective axes 12 and 13.
  • the thrust plate 8 is attached to the underside 2a of the center column 2.
  • a circulating steel strip 9 is provided.
  • the steel strip is fixedly connected via an outer column-side attachment 15 with the upper end of the support rod 16 and thus fixed in this position.
  • the steel strip 9 is fixedly connected via an inner column-side attachment 14 with the inner column 1.
  • the inner-column-side attachment 14 is provided in the lower end region of the inner column 1.
  • the “lower region” is understood to mean the region of the inner column 1 lying opposite the upper side I.
  • the inner column-side attachment 14 is in the inserted state in the immediate vicinity of the lower deflection roller 11, while the Outside pillar-side attachment 15 is located in the immediate vicinity of the upper guide roller 10.
  • the linear drive 22 is a high power density, i.e. with small length and small diameter of the drive motor 4, constructed with threaded spindle 5.
  • the threaded spindle 5 acts on a short spindle nut 6.
  • the drive can also be designed as a crank drive with threaded spindle.
  • other drives such as belt drives or fluid drives are possible.
  • the length of the threaded spindle 5 can be maximized, in which the cavity 18 of the foot 17 is utilized. This is done by providing a recess 19 in the foot 17, through which the unobstructed Tere end 7 b of the support tube 7 and similarly the threaded spindle 5 also protrudes with the same length in the cavity 18 of the foot 17.
  • the length of the threaded spindle 5 and consequently also the lifting height of the linear drive can be optimized. The thus optimized height adjustment takes place without negative influence on the appearance of the height-adjustable column, since the threaded spindle 5 can protrude quasi invisible into the cavity 18 of the foot 17.
