Definitions

  • This invention relates to an appliance for binding cable assemblies etc. with a strap placed around and closely adjacent to the cable assembly, the ends of which strap, after tensioning of the strap, are held by a lock member which appliance has a reel of strap, fixed in relation to a rotatable shaft, a device for guiding the strap to the lock member to be closed, a device for turning the shaft for the tensioning of the strap and an appliance for limiting the tension.
  • An object of the invention is to provide a device for limiting the strap tension in the case of an appliance of the type mentioned at the beginning, which even with varying diameter of the strap reel determines a substantially constant limiting tension for the strap and is easier to accommodate spatially in the implement.
  • This object of the invention is achieved, in that in the path of the strap in the guide direction, there is provided a movably supported cam, which deflects the strip under spring tension from a straight path, which cam is connected with a ratchet, which with the movement of the cam under tensioning of the strap against the spring tension comes into engagement with a gear wheel rigidly connected with the shaft.
  • An adjustment of the highest permissible tension can advantageously be effected, in that the cam is connected via a lever arm with the spring and can be adjusted on this lever arm.
  • the drawing illustrates a device for limiting the tension of the strap which prevents altogether excessive tensioning and thus overstressing of the strap and tension apparatus.
  • a reel 1 which is fixed in relation to a rotatable shaft 2 and can !be turned by means of a control knob situated on the shaft 2, a strap 3 runs through guides 4 and 5 to the locking device (not shown).
  • the belt 3 is deflected from a straight path by a cam 6 carried by a rod 7, which is pivotally supported at 8 in the body of the implement 9.
  • the rod 7 is formed as a twoarmed lever and has a lever extension 10, which is connected with a slider 11, having slots 12 which engage pins 13 fixed to the housing to ensure the guidance of the slider.
  • the slider 11 carries a ratchet 14, which is situated adjacent the periphery of a gear wheel 15, which is fixed for rotation with the shaft 2.
  • the slider 11 is biased by a spring 16 into a position removed from the gear wheel 15.
  • the cam 6 can be adjusted on the rod 7 for altering the leverage and thus for varying the force limit.
  • the appliance works in the following Way:
  • the strap 3 is tensioned by turning the shaft 2. As long as the tensioning of the strap 3 remains below a given limit value, the slide 11 remains under the influence of the spring 16 in the rest position with the ratchet 14 out of the path of the gear wheel 15. However if the component of the belt tension acting on the cam 6 exceeds the counteracting force of the spring 16, then the cam 6 is pressed down and the slider 11 is pushed to the left in the drawing, whereby the ratchet 14 comes into engagement with the teeth of the gear wheel 15, whereafter further tensioning movement of the shaft 2 is prevented.
  • lever arm and can be adjusted on said lever arm. 574-19
