Definitions

  • the invention relates to a method for producing a hammer, which has a hammer head with associated hammer eye, the Hammer head on a standardized wooden tool handle using an in one screw-in wood screw and one hole containing hardened locking plate and a ring wedge is attached, so that the hammer and handle form a solid unit.
  • a hammer made by another method e.g. known from DE-U-84 08 487.1, is used to secure the handle on A wedge pressed into the stem end, which spreads and holds the stem.
  • a stem protection sleeve is also provided.
  • the invention has for its object to improve the known methods for producing a hammer in such a way that a connection between the standardized tool handle and hammer head is created in the hammer produced with this method, which is so secure that it can never unintentionally come loose , and is so simple that it can be done by any non-specialist.
  • the wooden handle should be protected from damage and breakage if it fails.
  • the task is solved by the in the characteristic part of the Claim 1 specified method steps and additional Features.
  • the method according to the invention makes it a hammer for the first time created with a connection between standardized wooden handle and Hammer head that can never unintentionally come loose and that is so simple that it can be done by any non-specialist.
  • the wooden handle will fail in the event of damage and breakage protected.
  • the hammer produced with the method according to the invention has one standardized wooden handle, the end of the handle with a hardened protective sleeve is provided.
  • the hardened protective sleeve has a through hole that corresponds exactly to the dimensions of the wooden handle.
  • the dimension of the Hardened protective sleeve is made in such a way that the wooden handle that is in the The handle area is conical, is firmly pressed into the hardened protective sleeve and protrudes as far out of the sleeve as for fastening in the hammer head is needed.
  • the hardened protective sleeve can also be screwed, Rivets or notches can be firmly connected to the handle.
  • the wooden handle with the hardened protective sleeve is by firm contact of the hardened protective sleeve on the hammer head in the Hammer eye driven.
  • the wooden handle is made by driving one Ring wedge spread and fastened in the hammer eye.
  • a hardened one Locking plate that is larger than the dimension of the hammer eye by screwing a wood screw into the wood handle firmly with the Hammer head and the wooden handle connected.
  • FIG. 1 The figures of the drawings show that with the invention Process manufactured hammer in one embodiment.
  • the wooden handle 1 is equipped with a hardened protective sleeve 4, which in addition can be secured by screws, rivets or notches.
  • a hardened protective sleeve 4 which in addition can be secured by screws, rivets or notches.
  • the wooden handle 1 with the hardened Protective sleeve 4 is driven into the hammer eye 6 until the hardened protective sleeve 4 rests firmly on the hammer head 5.
  • the ring wedge 7 is hammered in Wooden handle 1 spread apart and firmly attached in hammer eye 6.
  • the hardened locking plate 9 is fastened with the wood screw 11.
  • the Wood screw 11 passes through the bore 10 of the hardened locking plate 9 and the bore 8 of the ring wedge 7 and is in the bore 2 for the Wood screw 11 of wooden handle 1 screwed tight.
