Definitions

  • the invention relates to a fixing clip mounting device and more particularly to a staple mounting device which comprises two arms which act radially on a fixed axis in order to keep thermal screens or any other type of element in position.
  • the staples of the type which comprise two arms which act radially on a fixed axis are put in place manually.
  • the assembly is performed by the operator by exerting pressure on the arms of the clip to allow the sliding of said clip on the fixing axis.
  • some pressure is recommended for the implementation of staples. Pressurizing is therefore more difficult and less precise manually, which can cause a disparity in the quality of assembly.
  • the manual placement of staples repeatedly can cause inconvenience and physical discomfort for the operator, especially at the fingertips. The physical inconvenience caused produces disparities in the quality of fixation of the clip.
  • US-A-5125296 discloses a clamping device in the form of a pneumatic gun having jaws actuated by means of a trigger.
  • the opening of the jaws requires an important place around the fixing zone. This device is too bulky, it does not allow access to narrow places.
  • the document GB-2002845 A discloses a mounting aid according to the preamble of claim 1.
  • the object of the invention is a light, manageable and precise device which makes it possible to set up a staple automatically and in places that are difficult to access while ensuring homogeneity in the quality of fixation.
  • the pusher comprises at least two distinct pressure zones which cooperate respectively with the arms of the staple.
  • the pusher is mounted in translation in a guide by limiting the relative rotational movements between said guide and pusher.
  • the pusher comprises a central orifice with a diameter greater than the diameter of the mounting axis.
  • the junction of the arms with the base of the clip are mounted in translation in grooves made in the x direction in the guide.
  • the present invention essentially relates to the tip of a staple assist tool, the following description does not describe the standard part and known per se of the tool which comprises the force transmission elements via pneumatic means or other equivalent means.
  • the tool comprises a connecting rod 1 between a pneumatic system, for example, known per se and a pusher 7, in order to transmit a thrust force to a staple 4.
  • a pneumatic system for example, known per se
  • a pusher 7 in order to transmit a thrust force to a staple 4.
  • the staple 4 serves to fix flexible walls of the heat shield type for example and comprises two arms 8 and 9 and a central hole 10. To be implemented, it is inserted on an axis 5 in a direction x.
  • the clip 4 is of substantially conical shape.
  • the arms 8 and 9 are attached to the base 17 of the cone diametrically opposite and extend above the top 18.
  • the arms 8 and 9 of the clip 4 are attached so that they protrude from the base 17 of the cone and that the base of the staple 4 is substantially in a rectangle.
  • the pusher 7 is mounted in translation along the x axis in a fixed guide 2 which forms the tip of the tool.
  • the clip 4 is positioned so that the arms 8 and 9 of the latter are in contact with an external part of the pusher 7.
  • the pusher 7, of rectangular shape comprises two distinct pressure zones 11 and 12, situated in opposite corners of the external part of said pusher 7, intended to cooperate respectively with the ends of the arms 8 and 9 of the staple 4.
  • the pusher 7 also comprises a sufficient recess in the central position so as not to interfere with the axis 5 for receiving the staple 4 during its assembly.
  • the guide 2 and the pusher 7 are of rectangular section so that the pressure zones always have the same orientation relative to the body of the tool.
  • grooves 15 and 16 may also be added to the guide 2 in order to limit the rotation of the clip 4 in the endpiece and may also serve to hold the staple so that the staple does not fall during the first step. 'surgery.
  • the operator places the staple 4 in the tip of the tool by making the free ends 13 and 14 of the arms cooperate. 8 and 9 respectively with the bearing zones 11 and 12, as shown in FIG. figure 1 , and applies the tip of the tool against a wall 6.
  • the figure 2 causes a translational movement to the pusher 7 by means of the pneumatic control which acts on the rod and which applies the staple 4 against the wall 6.
  • the arms 8 and 9 fold and move away from each other allowing a sliding of the clip 4 on the axis 5.
  • the arm 8 and 9 of the staple 4 are raised and tighten on the axis 5 so that the staple 4 is locked and holds the wall 6 in place.
