Definitions

  • the present invention relates to a method of riveting a gripping member on the body of a culinary article, for example a method of riveting a handle, a handle ... on the body of a saucepan , a stove, a fact-everything ...
  • the disadvantage of such a method is to require tolerances concerning the dimensions of the riveting holes of the two elements and the shaft of the rivet, extreme dispersions that may cause risks of discontinuity between the rivet and at least one of the holes once the riveting is completed, which can lead to sealing problems.
  • the present invention aims at overcoming the aforementioned drawbacks, that is to say to achieve a riveting process making it possible to reduce the tolerance requirements concerning the dimensions of the rivet holes and the rivet shank and to ensure greater reliability at the same time. riveting tightness.
  • the riveting process of the aforementioned type comprises, between the preparation step and the introduction step, a presentation step in which a penetration surface of the rivet is abutted. against a surface portion of a first member, the penetration surface being shaped so that during the introduction step, the rivet passes through the first member at a first riveting hole and drives the surface portion so as to wedge it between him and a second riveting hole which is carried by the second element and which receives the rivet.
  • the tolerances between the dimensions of the rivet shaft and those of the riveting hole carried by the second element are less restrictive, the clearance to allow the creep of a portion of the first element.
  • the jammed portion of the first element ensures an improvement in the tightness of the riveting.
  • the implementation of the present invention requires the use of a first element 1 (for example the body of a cooking utensil), a second element 2 (for example the grip member of a cooking utensil) and a rivet 3 (preferably of stainless steel) which comprises a barrel 4 (the part intended to pass through the two elements), a head 5 (the part which has not passed through the two elements), and a penetration area 6.7.
  • a first element 1 for example the body of a cooking utensil
  • a second element 2 for example the grip member of a cooking utensil
  • a rivet 3 preferably of stainless steel
  • a first preparation step the two elements 1,2 are correctly applied against each other.
  • the rivet 3 is correctly positioned relative to the two elements 1,2, more precisely, its penetration surface 6,7 is abutted against a surface portion 8,9 of the first element 1
  • the rivet 3 is driven (generally by a blow to its head 5) so as to pass through the two elements 1, 2.
  • the rivet 3 passing through the first element 1 at a first riveting hole 10, causes the surface portion 8,9 with it.
  • the result of this step is the creep of a volume portion 11 of the first element 1 which is wedged between the rivet 3 (more precisely, the barrel 4 of the rivet 3) and the second element 2 (more precisely, a second riveting hole 12 carried by the second element 2 in which is housed the shaft 4 of the rivet 3).
  • the free end 13 of the barrel 4 of the rivet 3 is struck so as to form a wedging bead 14 (the rivet 3 being held in place by a piece affixed against its head 5).
  • the jamming of the two parts 1, 2 is achieved by the conventional swelling of the rivet 3 and the creep of the driven volume portion 11 of the first element 1.
  • the dimensions of the barrel 4 and those of the second riveting hole 12 must allow the introduction of the material of the first element 1.
  • the profile of the penetration surface 6.7 and that of the surface portion 8.9 against which it is in abutment are shaped to facilitate the material drive of the first element 1 (there must be a certain angle between the two surfaces at their contact).
  • the penetration surface 6, 7 may advantageously have a conical, ogival or prismatic shape, for example.
  • the cross section of the penetration surface 6.7 may be circular, square or cross, for example. In the case of a conical surface, it is advantageous that the half-angle at the apex 15 is about 50 °.
  • the creep qualities also depend on the hardness of the rivet 3 compared to those of the two elements 1,2, respective dimensions of the rivet holes 10,12 and the thickness of the first element 1.
  • the creep in order to obtain a good jamming effect of the first element 1 between the rivet 3 and the second element 2, the creep must be such that the penetration height of the first element 1 in the second element 2 is greater than a quarter of the height of the second riveting hole 12.
  • each of the two elements 1, 2 has, before the preparation step, its riveting hole 10, 12.
  • the two riveting holes 10, 12 are arranged in the extension of one another, the barrel 4 of the rivet 3 is introduced from the two 10,12 holes, and the penetration surface 6, formed by the flange 6 of the rivet 3 connecting the head 5 to the barrel 4, is in abutment against the periphery 8 of the first riveting hole 10 (which is of the same size or dimension less than the second riveting hole 12).
  • Such embodiments make it possible to obtain a riveting in which the head 5 of the rivet 3 is flush with the surface of the first element 1, without having to form in the first element 1 a chamfer serving as a housing for the head 5: the introduction step, driving the volume portion 11 by the flange 6 causes a flattening of at least one of the two elements 1,2 under the head 5 (according to the rigidity of these elements 1,2).
  • FIG. 2 illustrates the riveting obtained when the first element 1 is more rigid (typically, with an elastic limit of 270 MPa stainless steel, for example) than the second element 2 (typically, aluminum limit elastic 70 MPa for example). In this case, the second element 2 is deformed due to the pressure exerted on the rivet 3 and transmitted by the first element 2.
  • first element 1 typically, with an elastic limit of 270 MPa stainless steel, for example
  • second element 2 typically, aluminum limit elastic 70 MPa for example
  • FIG. 3 showing the riveting obtained when the second element 2 is more rigid (for example stainless steel) than the first element 1 (for example aluminum). In this case, only the first element 1 is deformed because of the pressure exerted on the rivet 3.
  • the second element 2 is more rigid (for example stainless steel) than the first element 1 (for example aluminum). In this case, only the first element 1 is deformed because of the pressure exerted on the rivet 3.
  • the second element 2 has, prior to the preparation step, its riveting hole 12, unlike the first element 1.
  • preparation the first element 1 full (ie not perforated) is affixed against the second element 2 and covers the second riveting hole 12.
  • the free end 13 of the barrel 4 of the rivet 3 which forms the penetrating surface 7 is in abutment against the surface portion 9 of the first element 1 covering the second riveting hole 12.
  • the surface of penetration 7 pierces the first element 1 and thus makes the first riveting hole 10.
  • the second riveting hole 12 is used as a rivet guide 3.
  • Such embodiments have the advantage of eliminating a preliminary drilling step. from the first lement.
  • the second riveting hole 12 has, at its inlet 16, a chamfer 17 oriented in the direction of a reduction in the diameter of the hole 12 for a displacement in the direction of the rivet 3.
  • This chamfer 17 makes it possible to facilitate the creep of the first element 1.
  • the second riveting hole 12 has, at its outlet 18, a chamfer 19 oriented in the direction of a reduction in the diameter of the hole 12 for a displacement in the direction of the rivet 3.
  • This chamfer 19 makes it possible to receive a volume 11 of the first relatively large element 1 (wide part of the second riveting hole 12) while allowing the inflation of the rivet 3 to ensure by itself a good seal (narrow portion of the second riveting hole 12).
  • first element is the gripping member of a cooking utensil and for the second element to be the body of the utensil. It would also be possible for not only the first riveting hole to be made during the introduction step by the free end of the rivet shaft, but also the second riveting hole.
