Definitions

  • the invention relates to a socket for fitting tools with a conical eye.
  • This invention aims to remedy these drawbacks.
  • This invention as it is characterized, solves the problem of creating a socket, intended to be mounted at the end of a handle of standard and regular section, with a view to adapting it, to the fitting of '' tools with conical eyes such as picks, hoes, hoes, some hammers, weights, axes and oval picks.
  • This socket is mainly characterized in that it consists of a conical piece of semi-rigid material, of circular or oval section, conforming to the shape of the eye of the tool, comprising an orifice or an axial cavity of section corresponding to that of the tool handle.
  • the asphalting of the sleeve includes asperities intended to be housed in cavities of the same shape and of the same dimension produced at the periphery of the handle.
  • the protrusions arranged in the bore of the sleeve consist of annular ribs of section corresponding to that of grooves made at the periphery of the handle.
  • the ribs and the annular grooves arranged respectively in the bore of the sleeve and at the periphery of the handle have a section in right-angled triangle whose short side of the right angle is located on the side of the end of the handle on which the tool is mounted.
  • This embodiment is intended for allow the sleeve to be force fitted onto the end of the handle.
  • the sleeve can be molded onto the handle and, in this case, the production of cavities at the periphery of the handle can be obtained by any means making it possible to increase the roughness of the surface of the handle on a length corresponding to that of the sleeve, or by drilling one or more transverse orifices intended to fill completely or partially with material during overmolding.
  • the sleeve can be made in two half-shells intended to fit on the handle laterally and in juxtaposition, respecting the correspondence of the ribs and grooves arranged respectively in the bore of the socket and on the periphery of the handle.
  • the advantages obtained consist essentially in that it makes it possible to obtain a saving of wood of approximately 30% , a simplification of the machining, and a greater standardization of the handles without reducing the mechanical characteristics of these.
  • the drawing represents an assembly consisting of a pickaxe 1 in the eye 1a from which a cylindrical handle 2 is fixed by means of a plastic sleeve 3 .
  • the sleeve 3 the bore of which comprises triangular ribs 3a , has been, taking into account the section in right triangle and the orientation of the latter, force fitted on one end of the handle 2 having grooves 2a of the same section and the same spacing vector prior to engagement of the tip 1 over the sleeve 3, whose shape corresponds to that of the eye 1a of the tip 1.
  • the bore of the sleeve 3 is closed on the side of the base of the cone by a wall 3b which seals the assembly and thus prevents deterioration of the wood.
  • the sleeve 3 can be made in two half-shells which would be put in place by lateral fitting before fitting the tool which would thus ensure the joining of the two half-shells with the handle.
  • this socket 3 can be secured to the handle 2 , by molding, before mounting the tool and that, in this case, the longitudinal connection could be easily obtained by making streaks beforehand or by increasing the roughness over the sleeve length corresponding to the length of the sleeve.
  • One or two orifices drilled right through at this end of the handle, before overmolding, would also suffice, by penetration of the material in pasty form, at the time of overmolding, to ensure sufficient joining of the sleeve with the handle.
  • the socket according to the invention is intended mainly for the fitting of tools with a conical eye, but it could also be used, with profit, to ensure the adaptation of tools with cylindrical eye on standard handles provided that the socket is suitable for this kind of eye, that it has a shoulder at its end to prevent the tool from being pulled out and that its outer wall offers a slight taper in order to obtain a fastening of the assembly by tightening.
