Definitions

  • the invention relates to a chair, in particular swivel chair and movable wheel swivel chair with armrests.
  • each armrest has a support surface adapted to the size of an elbow exclusively as an elbow support, in which only the elbow joint is supported
  • Each support surface preferably has the shape of a circular cushion with a diameter between 10 and 18 cm, preferably 15 cm.
  • the support surface can also have the shape of a support trough which is open on one side.
  • the elbow support can be rotated about a vertical axis and, if necessary, attached to height-adjustable brackets or carrying brackets.
  • Each bracket can preferably be laterally adjustable inwards and outwards; the individual support bracket can preferably also be able to be given away forwards and backwards about an axis lying below the chair seat surface, preferably in the region of the main chair axis.
  • each armrest is rotatably attached to an armrest support about at least two, preferably three, vertical axes, in particular each armrest as an elbow support having a support surface adapted to the size of an elbow, in which only the elbow joint is supported.
  • each armrest is rotatable about two, preferably three axes, ensures that regardless of body size and body dimensions a person sitting on the chair and largely regardless of the sitting position that person occupies in the chair, the armrest or elbow support can be placed at any desired or required point, whereby the previous rotation or sliding of the elbow on the Armrest or elbow support and thus also the "erasing" of clothing or sleeves is eliminated.
  • each armrest 21 is only the size of an elbow support Elbow has adapted support surface.
  • the elbow support 21 has essentially the shape of a circular cushion with a diameter between 10 and 18 cm, preferably 15 cm. In a modified embodiment, however, the elbow support can also be designed as a support recess that is open on one side.
  • the elbow support 21 is fastened to an essentially tubular support bracket 22 and can be rotated relative to this support bracket about an essentially vertical axis 23, preferably through a range of 360 °.
  • each elbow support lies outside the center of the elbow support itself, as is indicated schematically in the drawing.
  • the height adjustability of the elbow support 21 is shown schematically in FIG. 1, see in particular the elbow support 21 shown on the left in the drawing.
  • a telescopic arrangement that can be locked in different height positions is preferably provided.
  • Each bracket 22 is pivotable about an axis below the chair seat 25, which is preferably in the area of the main chair axis.
  • an armrest support 1 is shown schematically in the form of an essentially square tube.
  • a bearing tube 4 is inserted for rotatably receiving a stub shaft 3 forming a first axis a .
  • a first mounting plate 5 with one end.
  • a second mounting plate 5 is pivotally attached by means of a shaft 7 forming the second axis b .
  • the shaft 7 is essentially formed by a rivet with rivet heads 7 '.
  • the armrest 2 is pivotally attached by means of a shaft 10 forming the third axis c .
  • the shaft 10 is formed by a rivet with two rivet heads.
  • a bearing 6 is interposed between the first mounting plate 5 and the second mounting plate 8.
  • Another bearing 9 is placed between the mounting plate and the underside of the armrest 2.
  • the armrest 2 consists of a mounting bracket 8 to which a plate, preferably plywood plate 13, is fastened by means of nuts, preferably drive-in nuts 12.
  • the plate 13 is covered with cushioning material in such a way that an open-sided, preferably elongated support trough is formed as the actual elbow support, which has a support surface adapted to the size of an elbow.
  • the armrest support 1 is preferably telescopically adjustable in the vertical direction, wherein each armrest support can also be pivotable about an axis lying below a chair seat surface, not shown.
  • FIG. 3 schematically shows part of the area shown, within which the armrest can be pivoted.
  • the reference line a + c corresponds to the starting position according to FIGS. 1 and 2, in which the two axes a and c are one above the other.
  • Figure 3 also shows different positions for the axes b and c . Intermediate positions are not shown.
  • the distances between the axes a and b on the one hand and the axes b and c on the other hand amount to 30 to 60 mm, in particular 40 mm, wherein according to a preferred embodiment the center distances are in each case the same.
