Definitions

  • the present invention relates to screw pinning staples as encountered in the aeronautical industry and it relates, in particular, to the particularities of these staples capable of making them more efficient.
  • inexpensive charged plastic materials having good serial molding properties can be used by offering, jointly, a good external appearance and coloring in the mass, thereby enabling them to be identify in order to make a visual selection of their diameters and / or their lengths.
  • plastics have a low mechanical resistance, much lower than metals, which has a number of drawbacks.
  • the invention proposes, in a pinning clip, a particular connection mode between a lower external plastic part and its corresponding upper external metal part.
  • connection mode is ensured by a special thread which allows the axial fitting by pressure of the hexagonal metal part in the plastic part, which has the advantage of simplifying assembly and possibly automating it, while allowing disassembly or a subsequent reassembly for the purpose, for example, of eliminating rubbery interposition products or else of replacing the damaged staple parts.
  • the invention also proposes an original method of anchoring the spacer of the staple branches which follows from the particular mode of connection of the two parts which has just been mentioned above.
  • a screw pinning staple as shown, necessarily includes a pair of staple branches 1 and 2, a branch spacer 3, the whole being located in the hole 4 practical in assembly 5, while a body marked 6 as a whole is supported on the assembly surface 7.
  • a spring 8 concentric with a rod marked 9 as a whole, while a support washer 10 serves to seat a nut 11 stopped, in abutment, by a cap 12 d 'end.
  • the rod 9 comprises, on one side, a partial smoothing at the bottom of the thread 9a which allows the nut 11 to turn madly and, on the other hand, a hexagonal part 9b which slides longitudinally in a corresponding female longitudinal imprint 6c practiced in the body 6.
  • This rod 9 is terminated by a part 9c which, by stamping, encloses the end parts of the branches 1 and 2 which, themselves, respect the radial positioning of the spacer 3 located between them.
  • the body 6 comprises a metallic upper part 6c comprising, on one side, a hexagonal external imprint and, on the other side, an internal recess whose role will be explained below.
  • connection mode to the invention which is identified (13) results from a male thread impression called artillery made in the middle zone 6a, force-fitted axially in the plastic sleeve formed by the part 6b.
  • thread flanks which are also helical, are substantially perpendicular to the axis for the faces opposite to the penetration and inclined in the manner of the usual thread flanks for what is on the side of penetration.
  • the hexagonal part 6a can be put in place by simple axial penetration pressure in the part 6b, while it can be easily removed by conventional unscrewing later.
  • the maintenance in position of the spacer 3 results, in a very simple manner, from the positioning of the parts 6a and 6b by placing a first washer 14 clamped by these parts, then by placing the branches 3a and 3b of said spacer between said washer 14 and another washer 15 located in line with the recess 16 made in part 6a so that the immobilization is thus acquired as soon as said two parts are put in place.
  • the clip is immobilized in rotation by a screwdriver nose (not shown) by enclosing the hexagonal imprint of the part 6a.
  • the screwing is carried out up to a preset torque compressing the spring 8 which ensures the tightening of the assembly 5 under the effect of its energy return (the tightening is necessary due to the presence of a polymerizable interposition product between the sheets constituting said assembly).
  • the extraction of the clip from the hole 4 after polymerization is carried out, according to the reverse maneuver, by unscrewing the nut 11, from where a push on the rod 9 towards the assembly and an output of the clip, by taking support at 17 under the hexagonal part of part 6a advantageously combined with ⁇ another support taking on the surface 7 of the assembly.
  • the invention proposes a pinning staple having improved conceptual properties allowing an increase in its mechanical qualities correlatively to a reduction in its manufacturing cost, in particular as regards the nature of certain materials used as well as through its own facilities for automated assembly.
  • the nature of the materials used is advantageously made up, for the upper part 6a, of an electrolytically protected steel and, for the lower part 6b, of the charged plastics material known commercially under the term of Rilsan, this term being an internationally registered trademark.
  • the plastic of the lower part 6b can be colored to meet a given code of staple diameter and / or staple length.
