Definitions

  • the invention relates to a seat for a standing aid or a chair.
  • DE 82 20 630 U1 shows a standing aid consisting of a base frame, a support frame connected to it, and a seat support fastened to the support frame and a seat body arranged on this seat support, the seat support with the seat body being adjustable in height along the support frame.
  • the seat support is attached to the support frame with a clamp.
  • the disadvantage here is that the attachment is not secure enough and that handling is cumbersome because two hands are always required for adjustment.
  • the seat body is also completely rigid and uncomfortable with respect to a lateral rotational movement.
  • a similar standing aid is known from DE 84 16 541 U1, here too the seat body can only be adjusted in height, the seat support consisting of tubes which can be moved in the support frame and which can be locked by means of an adjusting screw.
  • the seat support consisting of tubes which can be moved in the support frame and which can be locked by means of an adjusting screw.
  • a version with a height adjustment of the seat body by a gas spring is also known.
  • this standing aid is relatively complex and also does not offer the comfort of a lateral rotation of the seat body.
  • US-A-4,738,487 shows a standing aid consisting of a base frame, a support frame connected to it, and a seat support fastened to the support frame and a seat body arranged on this seat support.
  • the support frame has a latching body which is displaceable along the support frame and has latching holes which can be brought into engagement with latching lugs so that the seat support is locked in various positions.
  • FR-A-2 394 304 shows a standing aid consisting of a base frame, a support frame consisting of two tubes connected to it, and a seat support attached to the support frame and a seat body arranged on this seat support, the seat support with the seat body along the Support frame is adjustable in height.
  • the seat body is pivotally attached to the seat support.
  • the object of the present invention is to provide a seat for a standing aid or a chair, which has a slight lateral stand-up when the standing aid or the chair is arranged close to a workplace, e.g. an assembly line.
  • a seat for a standing aid or a chair for example of the latter type, is developed in such a way that the seat support has an upper surface, that a hole is arranged in the upper surface approximately in the middle, that in the upper surface around Bore are arranged at regular intervals around at least two inwardly curved grooves, that the grooves have a recess in their center and from there rise evenly on both sides, that the seat body carries a seat plate on its lower side, that a threaded rod extends from the seat plate extends downward through the bore of the upper surface of the seat support that curved grooves with depressions and rising flanks are also arranged in the bottom of the seat plate corresponding to the grooves of the upper surface of the seat support, that between the grooves of the upper surface of the seat support and the grooves of the seat plate Captively balls are arranged so that the threaded rod extends below the upper surface of the seat support through at least one washer, an axial ball bearing, another washer, an elastic element, another washer and is fast
  • this last-mentioned arrangement can also be used for standing aids without a height or incline-adjustable seat body.
  • Fig. 1 shows a plan view of the functional parts locking body 6 and seat support 8 of a seat.
  • the upper plate 48 with the elongated holes 10 and the locking lugs 11 is partially cut open and gives a view of the lower plate 49 with the bore 16 for the tubes of the support frame.
  • the seat support 8 is mounted on the axis 12 between the legs 42 of the locking body 6.
  • the legs 43 of the seat support 8 extend rearward and rest with their tabs 26 on the locking axis 22, which in turn is connected to the roller body 51, which in the locked position rest on the tubes of the support frame .
  • the locking means 14 which is designed as a thin rod and tilts laterally through the legs 42 of the locking body. Only the front edge of the handle part 9 can be seen.
  • a hole is made approximately in the middle thereof, around which three inwardly curved grooves 29 are arranged at regular intervals. These grooves have depressions 41 in their center, from which they become evenly flatter on both sides.
  • the grooves 29 serve as bearings for balls 33.
  • the counterpart to this is the seat plate 30 of the seat body 5 shown in FIG. 2, on which the cushion 31 is attached.
  • the seat body 5 is placed with the seat plate 30 down on the seat support 8, the threaded rod 34 passing through the bore 28.
  • the grooves 29 and 32 each form a housing for the balls 33 in pairs.
  • On the threaded rod 34 are a disc 35, an axial ball bearing 36, a disc 37, an elastic element 38, for example a rubber ring, a disc 39 and a nut 40 are arranged in succession from the seat plate 30 and the upper surface 52 of the seat support 8. If the seat body 5 is now slightly rotated, the balls 33 can move a little in the narrowing grooves 29, 32, since the elastic element yields somewhat. If the seat body is released, it rests itself due to the elastic force and favors itself by the grooves sloping into its center. The weight of the person using it enables the seat body to be turned easily and comfortably.
