Definitions

  • the present invention relates to a quick clamping system for hand-operated tools, such as hammers and the like, that is tools to which a handle is to be secured for use.
  • That operation is not always effective: prolonged use of the tool weakens said coupling, so that often it is necessary to take other measures, e. g. inserting another nail into said head to try to restore the coupling.
  • the object of the present invention is to overcome said drawbacks by providing a simple and practical clamping system which allows reliably securing such a tool to the handle, so that the tool can be used without any problem.
  • a hand-operated tool consisting of a hammer 1 to which the handle is to be clamped by the system of the invention. It is clear that said hammer 1 is a non-limiting example and represents in broad terms a tool to which the system of the invention can be applied.
  • the system of the invention essentially comprises two parts: head 3 of hammer handle 5, and an external clamping member 7, arranged to be applied to said handle head 3.
  • Said handle head 3 is made by copying thereon the profile of the slot of hammer 1 or other hand-operated tool into which the head is to be introduced, and by providing therein a longitudinal central hollow 9, transversal to the axis of hammer 1.
  • Said hollow 9 has the shape of a sunken wedge and has a plurality of-downward inclined cusp teeth 11. Hollow 9 ends at its bottom into a substantially rectangular chamber 13, capable of giving a resiliency to the two handle portions 15 created by said hollow 9.
  • Said head 3 is substantially frusto-conical in upward direction in order to make its insertion into the hammer slot easier and to improve its stability.
  • the head has, from the bottom to the top, a straight base 17, a tapered portion 19 and an upper straight portion 21, of reduced size with respect to base 17.
  • Said head 3 has the same cross-sectional shape (elliptical, oval or cylindrical) as the slot into which it is to be introduced.
  • External clamping member 7 comprises a wedge-shaped portion 23, with a profile corresponding to the profile created in hollow 9 of head 3, that is with a plurality of upward directed cusp teeth 25, capable of fitting into the corresponding recesses created by teeth 11 of head member 3.
  • clamping member 7 comprises an upper portion 27, with the same shape as the slot, from which said wedge-shaped portion 23 projects.
  • Upper portion 27 is intended to come in contact with the planar upper portion of head member 3.
  • head member 3 is introduced into the slot in hammer 1 or other tool to which the handle is to be secured, then wedge shaped member 7 is introduced into said head member whereby it becomes clamped with handle 5.
  • the system head 3 can no longer become disengaged since wedge 7 hinders flexion of the coupling flanges, which in any case always remain under the bevel of a triangle.
  • the system allows an integral unit to be formed with handle 5 of hammer 1 or other hand-operated tool, whereby a greater compactness and rigidity of the mounting is obtained.
