Definitions

  • the invention relates to a turnbuckle for a cable pull, with a housing and two threaded parts which are in mesh with one another, the first of which is a threaded bolt which is guided in a rotationally fixed and axially displaceable manner and which has a recess for hooking in the cable pull, while the second threaded part is axially fixed and rotatable is held in the housing and has a rotary handle.
  • Such turnbuckles serve a rotational movement, for. B. a handwheel attached to the turnbuckle, in a pulling movement of a cable or cable pull or, if appropriate, also in a pushing movement of the inner cable of a Bowden cable.
  • a known turnbuckle of this type (DE-C-43 21 985) has a substantially cylindrical housing which is to be rigidly attached to a frame and has at one end a receptacle for the outer cable of the Bowden cable and an opening in the outer surface which the thickened end of the inner cable of the Bowden cable can be inserted.
  • a threaded bolt is rotatably and axially displaceably guided in the housing and has at one end a recess which can be made to coincide with the opening in the casing of the housing, so that the inner cable can be hooked into this recess.
  • the threaded bolt is in threaded engagement with a nut which is rotatably and axially fixed in the housing and has a turning handle outside of the housing, onto which the handwheel can be wedged, for example.
  • the threaded bolt can thus be adjusted axially in the housing, so that a pull can be exerted on the inner cable of the Bowden cable.
  • EP-C-0 774 590 describes a turnbuckle in which the lateral recess for the cable pull is laid in the threaded portion of the bolt so that the Nut can be screwed over this recess. This shortens the overall length. However, since the thickened end of the cable pull must still be inserted from the side into the threaded bolt, there are restrictions with regard to the structural design of the turnbuckle housing and with regard to the installation position if the cable pull is to be hooked in only after the turnbuckle has been installed.
  • the object of the invention is to provide a small turnbuckle in which the cable pull is easier to hook.
  • This object is achieved in that the recess for the cable pull to the front side of the threaded bolt is open, so that a thickened end of the cable pull can be inserted from the front side, and since the recess has a shoulder inside, on which the thickened end in a position shifted relative to the insertion position can be locked in a tension-proof manner.
  • the turnbuckle need only be accessible from the front when hooking the cable pull, so that a very compact structure of the turnbuckle itself and installation in tight spaces is possible without the cable pull being hindered.
  • the cable end is inserted with its thickened end from the front into the threaded bolt of the turnbuckle, and then the thickened end is displaced so that it engages behind the inner shoulder of the threaded bolt and thus a tensile connection between the cable and the threaded bolt is established.
  • the displacement of the thickened end of the cable pull, with which the locking on the shoulder is effected, is preferably a rotation.
  • the mouth of the recess in the end face of the threaded bolt then has, for example, the shape of a keyhole, so that the thickened end of the cable pull, for example shaped like a hammer head, can be inserted in a specific angular orientation. Then the cable pull is around his Longitudinal axis rotated so that the hammer head reaches behind the shoulder.
  • the inner surface of the recess is preferably designed so that it forms a lock that prevents the thickened end of the cable pull from slipping off the shoulder.
  • guide contours can be provided in the recess, which automatically cause the rotation or, more generally, the displacement thereof when the thickened end of the cable pull is inserted.
  • this shift as well as the locking function can also be brought about by leaf springs which deflect the thickened end when it is inserted into the locking position and then hold it under tension in the locking position.
  • Figure 1 is a side view of the turnbuckle.
  • FIG. 2 shows an end view of the turnbuckle from the left in FIG. 1;
  • FIG. 3 shows an axial section through the turnbuckle and a threaded bolt accommodated therein;
  • Fig. 4 shows a partial section through the threaded bolt and the housing of the
  • FIG. 5 shows an enlarged section corresponding to FIG. 4, while hooking in a cable pull
  • FIG. 7 shows the threaded bolt of the turnbuckle according to another embodiment; and 8 shows an end view of the threaded bolt from the left in FIG. 7.
  • the turnbuckle 10 shown in its entirety in FIGS. 1 and 2 has a cylindrical housing 12 made of plastic, which is provided at one end with two radially projecting, diametrically opposite fastening flanges 14. At this end, the housing 12 has a plateau 16, which forms a grommet 18 for supporting the outer cable of a Bowden cable, not shown. In the grommet 18, a keyhole-shaped opening 20 is formed on the face side, which allows the thickened end of an inner cable of the Bowden cable to be inserted into the interior of the housing 12.
  • a nut 22 is snapped in such a way that it can be rotated in the housing 12, but is held in a defined position in the axial direction (FIG. 3).
  • the nut 22 is divided in a diametrical dividing surface 24 into two identical half shells 26 which can be injection molded from plastic. Wedge grooves 28 are provided on the circumference of the nut 22 for a hand wheel (not shown) or a comparable turning handle.
  • Two diametrically opposed radial protuberances 30 are arranged along the circumferential wall of the housing 12 and form guide channels 32 in the interior of the housing for securing against rotation and axially guiding a threaded bolt 34 (FIG. 3).
  • the threaded bolt 34 is also made of plastic and has at one end two radially projecting, diametrically opposite cams 36 which engage in the mentioned guide grooves 32 in the protuberances 30 of the housing.
  • a keyhole-shaped recess 38 is formed in the end face of the threaded bolt 34, the shape of which corresponds to the opening 20 of the housing 12.
  • the opening 20 has the cross-sectional shape of a circle with two diametrically opposed extensions 40.
  • the recess 38 of the threaded bolt also forms two axially extending channels 42 which correspond to these extensions.
  • the recess 38 is widened to form pockets 44 which adjoin the channels 42 in the circumferential direction and each extend over a circumferential angle of approximately 90 °.
  • a wall of each channel 42 forms a guide contour 46 which is arcuate to the rear end of the pocket adjoining this channel 44 runs.
  • the other wall of the channel 42 jumps back to form the nose 48 to the front end of the pocket 44 and ends there in a shoulder 50 which runs parallel to the end wall of the threaded bolt.
  • FIG. 5 illustrates the situation in which one end of a cable pull 52, for example the inner cable of a Bowden cable, is inserted through the opening 20 into the recess 38 of the threaded bolt.
  • a hammer head-like thickening 54 is formed which, with its projecting ends, first engages in the extensions 40 of the opening 20 and then in the channels 42 of the recess 38 and is guided therein.
  • the thickening 54 runs onto the guide contours 46, so that the thickening is rotated by approximately 90 ° and then lies with its ends in the pockets 44. If the cable pull 52 is then pulled back a little, the thickening 54 rests on the shoulders 50, so that the cable pull 52 is positively locked behind the shoulders 50.
  • the lugs 48 prevent the thickening 54 from slipping off the shoulders 50.
  • the threaded bolt 34 which is held in the housing 12 in a rotationally fixed manner, moves axially in the housing 12, so that a pull is exerted on the cable pull 12 via the thickening 54, as shown in FIG.
  • the outer cable, not shown, of the Bowden cable is supported on the grommet 18, so that an actuating force can be transmitted to an organ to be actuated via the Bowden cable.
  • Figures 7 and 8 show a threaded bolt 56 for a turnbuckle according to a modified embodiment.
  • the recess 38 is formed continuously along the entire length of the threaded bolt, and the shoulders 50 lie on the bottom of axial grooves 58, which are offset by 90 ° from the axial channels 42, but are separated from them by webs 60.
  • the webs 60 each end at a distance from the rear end of the recess 38.
  • leaf springs 62 are injection molded onto the walls of the channels 42, which deflect the ends of the thickened portion 54 into the grooves 58.
  • the large axial length of the grooves 58 prevents the thickening 54 from slipping off the shoulders 50 when the tension of the cable pull is reduced somewhat.
  • the thickening can only come off again the grooves 58 emerge when the cable is inserted so far that the thickening behind the ends of the webs 60 can re-enter the channels 42. If the cable pull is to be released from the threaded bolt 56, the force of the leaf springs 62 must also be overcome by a torque exerted on the relatively torsionally rigid cable pull.
  • the webs 60 can also be shortened to lugs corresponding to the lugs 48 in FIG. 4 or omitted entirely.
  • the thickening of the cable pull is prevented from slipping off from the shoulders 50 solely by the action of the leaf springs 62, which are then constantly in contact with the thickening when it abuts the shoulders 50.
