Definitions

  • the invention relates to a tension band, in particular for binding elongated objects such as cable harnesses, consisting of a band tongue serrated on both sides, a clamping wedge which is connected at its thinner end to one end of the band tongue and serrated on both wedge surfaces, and a clamping head, which for receiving the clamping wedge and the free end of the band tongue to be clamped contains a clamping opening which is delimited on opposite sides by converging opening surfaces, one of which is used to support the clamping wedge on one of its wedge surfaces and the other together with the other wedge surface for formation a clamping gap is intended for the band tongue.
  • the initial clamping takes place in that the clamping part is drawn into the clamping opening as a result of its direct connection to one end of the band tongue, and the teeth of the clamping part and the band tongue come into engagement with one another in the clamping gap. If, however, the strap remains loose after assembly, which can be due to an accident or in some cases also on purpose, there is a risk that the clamping wedge is not drawn into the clamping opening and the teeth of the clamping wedge and the strap tongue remain disengaged, so that the band tongue can be pulled out of the clamping gap. It is known to provide the clamping head and the clamping band near the clamping wedge with cooperating stops (US Pat. No. 3,654,669); however, the stops are so far from the wedge that it is not prevented from assuming a full solution position.
  • the invention has for its object to provide a strap of the type mentioned, in which the tooth engagement is guaranteed even if the full strap tension does not act after assembly.
  • the solution according to the invention is that the opening surfaces of the clamping head have a spring tongue, which resiliently protrudes into the clamping opening and each of which engages behind an edge of the clamping wedge.
  • the opening area of the spring tongue or this is essentially concave with the subsequent opening area of the clamping head, so that the clamping wedge, when it is drawn into the clamping head but is not under full tension, of the opening areas formed by the clamping head including the spring tongues in one Type of cavity is kept, which narrows behind the clamping head (or at least one edge of the clamping head).
  • the retention effect of the spring tongues can be further improved in that at least at the end they have a tooth which interacts with the toothing of the clamping wedge, preferably even being serrated over their entire opening area.
  • the opening surfaces of the clamping head should also be serrated in the area which is not designed to be resilient in the form of the spring tongues, the clamping wedge in the tensioned state being supported to a substantial extent, if not completely, in this non-resilient area of the opening area. This ensures that the spring tongues are not or only slightly acted upon by the supporting force to be applied to the clamping wedge and therefore do not deform significantly in the tensioned state, so that they can still exert their restraining effect in the event of an accidental loosening of the band.
  • the spring tongues and the part of the clamping head behind them are equipped with cooperating support surfaces which ensure that the spring tongues can only be pushed back under the clamping force to such an extent that their teeth are still in effective retention engagement with the Wedge can get.
  • the tensioning strap which - unless otherwise stated here - is expediently of the type described in EP-A 0 125 637, comprises a strap tongue 1, at one end of which the clamping wedge 2 is arranged in one piece, while the other, free end is guided through the clamping gap 3, which is formed in the clamping head 4 in the clamping opening 5.
  • the clamping opening is delimited on opposite sides by toothed opening surfaces 6 and 7 converging downwards (in the drawing). These are opposed by toothed wedge surfaces 8 and 9 on the side of the clamping wedge 2.
  • the wedge surface 8 of the clamping wedge is supported on the opening surface 6 of the clamping head, while the wedge surfaces 7 and the opening surfaces 9 enclose the clamping gap 3 and therein the free end of the band tongue 1. It does not matter whether the free end of the strap tongue 1 is inserted between the clamping surfaces 7 and 9 or between the clamping surfaces 6 and 8, which means a considerable ease of assembly, because the tensioning strap can be installed blind.
  • spring tongues 10, 11 are provided, which form the upper part of the opening surfaces 6 and 7 in the example shown.
  • the spring tongues In the relaxed state (FIG. 1), the spring tongues protrude a little into the clamping opening 5, to the extent that the clamping gap 3 remaining next to the clamping wedge 2 is no further than the thickness of the strip tongue 1 when the arrangement relaxes and the clamping wedge 2 is shifted a little upwards in the clamping head 4.
  • It can be on the lower end of the wedge or on the strap Stop is provided, which cooperates with the lower surface of the clamping head 4 such that the clamping wedge can only come out of the clamping head so far that the effect of the clamping tongues is still guaranteed.
  • clamping tongues are concave in the longitudinal section shown, which can be seen in particular in the clamping tongue on the right in FIG.
  • the clamping wedge is completely or at least up to the edge turned by the tooth 12 and turned backwards by the spring tongue, the end tooth 13 of the spring tongue reaching behind the tooth 12.
  • the support of the clamping wedge or the tensioning band by the opening surfaces 6, 7 takes place mainly near or below the root 14 of the spring tongues, so that these are not or only slightly deformed and therefore even if they consist of a plastic with a decreasing restoring force , are effective in the event of accidental loosening of the band for the retention of the clamping wedge. It is therefore important in this context that only a part of the teeth of the clamping head is located on the spring tongue, while the lower teeth are arranged rigidly on the clamping head outside the spring tongue area. If you connect the tips of all the teeth together, at least in the untensioned, preferably also in the tensioned state, a curved line that penetrates more and more into the clamping opening from bottom to top.
