Definitions

  • the present invention relates to an intercentric pliers of the type described in the preamble of claim 1.
  • the multi-purpose pliers of this type make it possible to carry out a guided, and therefore precise and reliable, guidance with two branches made by cold forging and a plate attached to the branch branch.
  • the flat shape of the wafer leads to a large thickness of the inter-branching branch and to a correspondingly large thickness of the other branch.
  • the invention aims to lighten the branches of the clamp.
  • it relates to an interconnect pliers interchange of the aforementioned type, characterized in that the plate has, in side view, a general shape of ⁇ .
  • the multi-socket pliers according to the invention may comprise one or more of the features of claims 2 to 9.
  • the pliers manifold 1 shown assembled on the Figures 1 and 6 assumed to lie flat on a horizontal surface, consists of a double-piece branch 2 obtained by cold forging, shown in FIG. Figure 2 of a branch 3 also monobloc and obtained by cold forging, represented on the Figure 3 , a plate 4 shown on the Figures 4 and 5 , and a jaw opening control device 5 visible on the Figure 6 .
  • the branch 2 has at its distal end or before a first jaw 6 having an appropriate gripping thread 7. It also comprises, from this jaw, an intermediate region 8 in which is formed a hollow 9, then a rear or proximal portion 10 forming a handle. Conventionally, the portion 10 may be coated with a sheath 11 made of plastic or elastomer.
  • the jaw 6 and the part 10 have the same thickness E ( Figure 6 ) and have a generally rectilinear shape, while the region 8 has a reduced thickness and presents in elevation ( Figure 2 ) a generally bent shape whose concavity is turned downwards in the drawings.
  • the hollow 9 ( Figures 2 and 6 ) consists of a central recess 12 with a flat bottom whose depth is E / 2 and whose bottom has a circular orifice 13 of diameter D1.
  • This recess 12 is lined at each longitudinal end of a flat step 14 of height close to E / 4.
  • the steps are limited at their outer ends by respective shoulders 15 which converge strongly towards each other towards the back of the clamp, that is to say towards the top of the Figure 1 .
  • the lines D1 and D2 corresponding to these shoulders form an angle of approximately 50 °.
  • each step 14 protrudes a substantially frustoconical stud 16 from cold forging.
  • a recess 17 is formed under each stud.
  • a projection 18 is provided on the inner edge of the proximal step 14. This projection has a proximal face 19 inclined at about 45 ° and a distal face 20 substantially vertical, which also defines the portion 12 of the recess.
  • the outer surface of the branch 2 namely its lower surface in the illustrated position, is flat except for the two recesses 17.
  • the branch 3 also has an outer surface (its upper surface in the illustrated position) which is flat. It has the thickness E in its front or distal region which defines its jaw 21, as well as in its rear region 22 forming a handle. In its intermediate hinge region 23, the thickness of the branch 3 is E / 2.
  • This region 23 is substantially rectilinear in elevation ( Figure 3 ) and has an elongated slot 24 with a plurality of circular notches 25 of diameter D2 smaller than D1 which interpenetrate, as is conventional in the multiple-grip pliers.
  • the minimum width of the light 24 between the notches 25 is D3 ⁇ D2.
  • the handle 22 is coated with a sheath 26 similar to the sheath 11.
  • the plate 4 has, in elevation view following the Figures 1 and 4 , the contour of the hollow 9 of the branch 2, from one shoulder 15 to the other.
  • longitudinal section Figure 5
  • it has a shape in ⁇ , that is to say that its two end portions 27, which are flat and lie flat on the respective steps 14, are in a plane shifted downwards by relative to its central portion 28, which is also flat.
  • Each portion 27 is pierced with a circular orifice 29 flaring upwards, while the portion 28 is pierced with a circular orifice 30 of diameter D3, bordered above a shallow circular bowl 31.
  • the inclination of zones 32 of connection between the parts 27 and 28 is the same as that of the edge 19 of the projection 18.
  • the control device 5 consists of a stepped pin 33 having a lower portion 34 of diameter D1, an intermediate portion 35 of diameter D2, an upper portion 36 of diameter D3 and an end portion of smaller diameter.
  • the pin 33 traverses from bottom to top the orifice 13, the light 24 and the orifice 30.
  • a cup 37 is positioned in the bowl 31, a washer 38 is riveted on the upper end of the pin 33, and a spring frustoconical helicoid 39 is compressed between this washer and the bottom of the cup 37.
  • the branch 2 is placed on a horizontal support, with the recess 9 turned upwards, then the part 34 of the pin 33 is inserted into the orifice 13.
  • the branch 3 is then placed with its flat face turned upwards and its intermediate region 23 placed on the bottom of the portion 12 of the recess 9, a notch 25 slipping on the portion 35 of the pin.
  • the plate 4 is then placed on the assembly, so that the portion 36 of the pin 33 passes through the orifice 30 and each pin 16 passes through an orifice 29.
  • the cup 37 and the spring 39 are put in place, then the washer 38 is fixed by riveting on the upper end of the pin 33. Finally, the two pins 16 are riveted in the orifices 29.
  • the thickness of the branches 2 and 3 can be limited to E, that is to say twice the thickness of the intermediate hinge zones 8 and 23 of the two branches.
  • the handles of the two branches have a limited approximation so as to prevent the pinching of the fingers of the user.
  • the stop is provided, for the notch 25 before, by the contact of the two jaws and, for other notches, by the contact of the back of the region 23 with the front edge 20 of the projection 18.
  • This projection can also, alternatively, also limit the closure of the forceps for the front notch.
  • substantially vertical orientation of the edge 20 has the result that even if the user forces the tool towards the closure, it does not result in any solicitation of the wafer 4 at the expulsion upwards.
  • the studs 16 become loose or deform by shearing, the plate abuts, during tightening, on the convergent shoulders 15, which limits the deformation of the elements of the clamp and ensures the keeping the plate in place.
