Definitions

  • the invention relates to an adjusting device for an adjusting element arranged on an axis, which can be adjusted as desired in both directions of rotation by means of a drive and can be locked in any set position.
  • Such an adjustment device is known from DE-Al-195 18 424 and from EP-B1-0 662 403.
  • the known adjusting devices have an extremely complicated structure and are therefore complex to assemble and cost-intensive.
  • the object of the invention is to improve an adjusting device of the type mentioned in such a way that it has a simple structure which allows quick assembly and can be produced inexpensively.
  • Fig. La, b cross sections through an embodiment of an adjusting device, wherein the cuts are in planes displaced by 90 ° to each other;
  • Fig. 2a, b cross-sections along line II-II of Fig la and b; 3a, b variants of an adjustment device with levers;
  • FIGS. 1 a, b and 2 a, b has an adjusting member 2 arranged on an axis 1, which can be adjusted as desired in both directions of rotation by means of a drive 3.
  • the drive consists of a handwheel 4, which is connected in a rotationally fixed manner to a driver 5 with angled projections 6, 6 ' .
  • the projections 6, 6 'of the driver 5 engage in two jaws 8, 8' which can be moved along the central circumference of a circular housing 7 and which can be moved together within the housing 7 by means of the drive 3, for example in the position shown in FIG. 2b .
  • a motor drive in particular an electric motor drive (not shown) can also be used.
  • the jaws 8, 8 ' are supported on one side in the exemplary embodiment shown in FIGS. 1, 2 on a common bearing 9, which here as a roller, ie. H. is designed as a roller bearing, the jaws 8, 8 'having correspondingly designed support surfaces.
  • an output body 10 is fixedly connected to it.
  • the output body 10 is arranged coaxially to the axis 1 and has a rectangular cross section.
  • the output body 10 is in contact with the arms 11, 11 'of a scissors arrangement 12 which are arranged so as to be pivotable about a common pivot axis 13, the corresponding counter-arms 14, 14' associated with the arms 11, 11 'having the free ends 15, 15' the jaws 8, 8 'are in contact.
  • the arms 11, 11 ', 14, 14' of the scissors arrangement 12 are preferably in contact with the ends 15, 15 'of the jaws 8, 8' or with the driven body 10 without play.
  • a spring 16 can be arranged between the counter arms 14, 14 ', which presses the counter arms 14, 14' of the scissors arrangement 12 against the ends 15, 15 'of the jaws 8, 8'.
  • the pivot axis 13 can be arranged at any height between the output body 10 and the ends 15, 15 'of the jaws 8, 8', whereby the lever forces of the scissors arrangement 12 can be varied.
  • the contact between the arms 14, 14 'of the scissors arrangement 12 and the ends 15, 15' of the jaws 8, 8 ' can be flat (see FIG. 2a), partial or punctiform (not shown).
  • the flat or partial surface contact surface between the jaws 8, 8 'and the arms 14, 14' can be made at any angle to the radius of the housing 7. Accordingly, the contact can be provided at any point on the ends 15, 15 'of the jaws 8, 8' in the case of a punctiform design. Through these measures, the friction between the jaws 8, 8 'and the housing 7 can be influenced by different force application.
  • the drive 3 consists of a lever 17 connected in an articulated manner to the jaws 8, 8 '. With this linkage, the spring 16 is first compressed when the lever 17 moves, so that the jaws 8, 8 ' and thus the adjusting member 2 is possible, since this reduces or almost eliminates the pressure of the jaws 8, 8' on the housing 7.
  • an elongated lever 17 ' is shown in dashed lines, which is rotatably mounted here in the region of the bearing 9 between the jaws 8, 8'.
  • this extended lever 17 ' the free ends of the jaws 8, 8' are attached to the lever 17 'with play in order to avoid pressing one of the jaws 8, 8' against the housing 7 when the lever 17 'is actuated.
  • 3b shows a lever 17 "which is rotatably arranged coaxially to or on the axis 1.
  • the jaws 8, 8 ' are connected to the lever 17" with play, with no spring between the jaws 8, 8 'is provided.
  • the arms 11, 11 'of the scissors arrangement 12 which are connected to the driven body 10 are extended and are in contact with the other ends of the jaws 8, 8', a bearing being dispensed with.
  • FIG. 5 different cross sections of the Abtriebskö ⁇ ers 10 are shown.
  • the jaws 8, 8 'with different lengths and also bearings 9' lie on the circumference of the housing 7 (see in particular FIGS. 5a and f).
  • the transmission paths can be designed from soft to hard, and the respective contact surfaces between the driven body 10 and the arms 11, 11 'can be varied as desired.
  • 5f shows an embodiment variant in which the force relationships with respect to the points of attack A and B of the driven body 10 when it rotates in the direction of the arrow on the arms 11, 11 'and on the jaws 8, 8' via the counter arms 14, 14 'are approximately the same size are.
  • FIG. 6a which have a plate 18 which is freely rotatable with respect to the driven body 10, allow further modification possibilities.
  • the plate 18 shown in FIG. 6a enables the respective desired axes of rotation of the scissors arrangement 12 to be defined differently, which, as shown there, also do not have to coincide.
  • FIG. 6b shows a variant with a plate 18 ', an arm 11' being fixedly connected to the plate 18 ' , which, as shown, can also be arranged eccentrically to axis 1 and which additionally makes it possible for the pivot axis 13 'of the scissors arrangement 12, here the arm 11, for. B. can be shifted to a projection 19 of the plate 18 '.
  • the eccentric mounting of the output body 10 'in turn results in other force relationships which act on the jaws 8, 8' via the arms 11, 11 'and the counter arms 14, 14 ' .
  • the jaws 8, 8 ' By a drive 3 z. B. a handwheel 4 or a lever 17 or a motor, the jaws 8, 8 'can be moved in both directions of rotation within the housing 7.
  • the sections of the jaws 8, 8 'contacting the housing 7 are completely (s. Z. Fig. 2) or partially (s. Z. Fig. 5f) adapted to the interior of the housing 7 so that there are contact surfaces between them.
  • the adjusting member 2 can be a coil, a gear or any other element that transmits a movement.
  • the adjusting member 2 acts on the adjusting member 2, usually from the object to be adjusted z.
  • B. a height or curvature adjustable lumbar support, a load that can be supported by the spring 16 or is only applied by the spring 16.
  • a load is transmitted to the Abreteskö ⁇ er 10, which causes the scissor arms to try to open by its contact with the scissor assembly 12 and thereby exert pressure on the jaws 8, 8 ', which are supported on the opposite side and thus open prevent scissor assembly 12, d.
  • H. there is a lock there is a lock.
  • At least the scissor assembly is made of a rigid material, e.g. B. made of a preferably abrasion-resistant metal.
  • a rigid material e.g. B. made of a preferably abrasion-resistant metal.
