  • Traditional rack clamps are made of plastic material, are made up of a flexible toothed strip, finished at one end in a head with a tubular structure, traversed by a passage, with a section approximately equal to that of the toothed strip, through which it is introduces and passes said strip.
  • This passage is partially interrupted by an internal ratchet, insertable between the teeth of the portion of the toothed strip inserted through the passage, for its retention.
  • the toothed strip once fitted to the clamp on the elements to be fastened, protrudes from the head in a portion that is cut with an auxiliary cutting instrument.
  • the aforementioned torsion can be difficult and require some effort, such as damaging the fingertips and even causing certain injuries to the hands or arms, such as tendinitis or joint pain, due to the high efforts that in certain cases are necessary to apply until achieve strip cutting.

  • the device of the invention makes it possible to carry out the cutting of the protruding section of the toothed strip with less effort than if the twisting were carried out directly by hand, thus allowing its application to self-cutting clamps with toothed strip of relatively high sections .
  • the device of the invention is designed for application in self-cutting rack clamps, of the type described above.
  • the device is made up of a piece of tubular structure comprising a central core, provided with a passage with a section approximately equal to that of the toothed strip of the clamp, and two external fins that project in opposite directions from the central nucleus, perpendicular to the passage of the nucleus and have lateral support surfaces for the buds of the user's fingers.
  • the commented piece can be related to the head of the clamp through connections that are easily separated or broken.

  • the piece that is the object of the invention can be independent of the head of the clamp, having both components with opposable and snap-fit shapes, which are then easily detachable.
  • the union between the piece of the invention and the head of the clamp is carried out by adhesion, using any adhesive means. , or welding so that at the moment of twisting said conformations, if any, break.
  • the welding is carried out by heat welding.
  • the end of the toothed strip will also go through the core of the device of the invention, through its passage, partially protruding.
  • the clamp will be tightened by pulling the end of the protruding portion of the flexible strip, while holding the head of the clamp. Once tensioned, the fingers rest on the fins of the device of the invention and said device is rotated, twisting the toothed strip easily and thereby pressing said strip against the cutting blade mounted in the conduit that passes through the head of the clamp, until it is cut. During twisting, the excess length is cut off by the clamp blade.
  • the effort to cause the device to rotate will be sufficient to cause said head to separate and allow it to rotate.
  • the part itself incorporates at least one cutting blade, preferably located in the internal area. of the mouth of the passage, so that it remains in contact with the excess section of flange, producing its cut by twisting the piece in the same way as in the case previously exposed.
  • Figures 1 and 2 show in front and rear perspective, respectively, a device made according to the invention.
  • Figure 3 is a perspective of the head of the clamp with the device of the invention in a position facing said head.
  • Figure 4 shows in perspective a self-cutting rack clamp, fitted on a set of cables or tubes.
  • Figure 5 corresponds to detail A of figure 4, on a larger scale.
  • Figure 6 shows the cutting operation of the excess toothed strip section, with the device of the invention.
