Definitions

  • the invention relates to a socket for connecting a handle to a conical eye of a tool according to the preamble of claim 1.
  • a socket of this type is known in the prior art from document DE-U-1 953599.
  • None of these sockets is designed to be press fitted between the eye of the tool and the end of the handle nor to allow the use of a standard handle, of regular section, on a tool with eye of any section, such as, for example, a cylindrical handle in an oval section 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 the '' tools with conical eyes such as picks, hoes, serfouettes, certain hammers, weights, axes and oval picks.
  • This socket consisting of a piece of semi-rigid material, externally conforming to the shape of the eye of the tool, and internally that of the handle of the tool, the bore of which has asperities intended to be housed in cavities of the same shape and of the same dimension produced at the periphery of the handle, is characterized in that the asperities and the cavities have a right triangular section whose short side of the right angle is located towards the end of the handle on which attaches the tool and in that the connection between said roughness and said cavities secures the socket with a handle of regular section.
  • the sleeve is placed on the handle by force fitting.
  • the sleeve is placed on the handle by overmolding.
  • 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 of which is fixed a cylindrical handle 2 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 of the ends of the handle 2 having grooves 2a of the same section and the same spacing, before conventional fitting of the pick 1 over the socket 3, the shape of which corresponds to that of the eye of the pick 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 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.
