Definitions

  • the invention relates to a hammer, the handle of which is fastened with the interposition of a sleeve in the hammer head.
  • the hammer head is provided with an oval opening, which completely penetrates the upper end of the hammer handle equipped with a protective sleeve.
  • the opening in the hammer head is adapted to the shape of the end of the handle.
  • a wedge preferably a ring wedge, is driven into the end of the handle.
  • the hammer head can still be secured with a cross pin that penetrates both the hammer head and the handle end.
  • This inwardly tapering shape of the bearing eye makes it difficult to drive in the stem end because the middle region of the bearing eye, which forms the narrowest passage, must be passed through by the stem end. If the handle end is driven in too violently, it will be damaged or even broken off, provided the protective sleeve does not enclose the handle end tightly enough and forms a secure hold.
  • the invention has for its object not only to simplify the fastening of the hammer handle in the hammer head of the generic type of hammer, but also to improve it in such a way that a reliable fastening between hammer handle and hammer head is achieved.
  • the sleeve is composed of a section with a round cross section and a section with an oval cross section, the handle end of the hammer handle fitted with the sleeve being drivable in a bore of the hammer head such that the section of the sleeve with the round cross-section lies completely in the bore of the hammer head and is held there in an interference fit.
  • the complex widening of the bearing eye and the difficult driving in of the end of the handle is avoided in the inventive design.
  • the sleeve can consist of a one-piece metal body, the section with the oval cross section being approximately twice as long as the section with the round cross section. This ensures that the hammer handle is not only held securely in the hammer head, but that the hammer handle is protected against damage when the hammer blows below the hammer head.
  • the transition point between the section with the round cross section and the section with the oval cross section can be designed as a truncated cone. This simplifies the manufacture of the one-piece metal sleeve.
  • the handle end of the hammer handle can be positively received in the sleeve, the head of the handle end protruding from the cylindrical part of the sleeve. This has the advantage that the free area of the end of the handle can widen when a wedge is driven in.
  • the handle end of the hammer handle can be driven with the cylindrical part of the sleeve into a cylindrical bearing eye of the hammer head.
  • the head of the end of the handle appropriately receives a ring wedge.
  • the bearing eye of the hammer head is advantageously designed as a blind hole.
  • the ring wedge used for fastening is driven into the handle end of the hammer handle by about 2 mm in order to get the correct position.
  • the ring wedge is driven completely into the handle when the bottom of the blind hole is touched and spreads the end of the handle apart to ensure that the hammer head is firmly seated.
  • the handle end of the hammer handle which is not completely driven into the bearing eye of the hammer head can have an annular groove which can be filled with an adhesive, the adhesive serving as a fixed bearing shell in the bearing eye of the hammer handle after drying out.
  • the first handle attachment is shown in FIGS. 1-4.
  • the hammer identified by the reference number 10 consists of a hammer head 11 made of steel, a wooden handle 12 and a steel sleeve 13.
  • the hammer head 11 is provided with a continuous bore 14 which serves as a cylindrical bearing eye .
  • the steel sleeve 13 is composed of a section 15 with a round cross section and a section 16 with an oval cross section.
  • the transition point between the section 15 with the round cross section and the section 16 with the oval cross section is designed as a truncated cone 17.
  • Section 16 is approximately twice as long as section 15.
  • the handle end 18 of the handle 12 is equipped with the steel sleeve 13 in such a way that the head of the handle end 18 protrudes from the cylindrical section 15 of the steel sleeve 13.
  • the shape of the handle end 18 is precisely adapted to the interior of the steel sleeve 13.
  • the cylindrical section 15 is driven completely into the bore 14. As can be seen from FIG. 1, the cylindrical section 15 of the sleeve 13 extends over approximately two thirds of the interior of the bore 14. The remaining part of the bore 14 is filled by the handle end 18. After driving in the handle end 18, a ring wedge 19 is driven into its head, which spreads the upper part of the handle end 18 and ensures a secure hold of the handle 12 in the hammer head 11.
  • An additional securing of the handle 12 in the hammer head 11 can also be effected in that the sections 15 and 16 of the steel sleeve 13 are each provided with a dowel pin 20 which crosses the hammer head 11 or the handle end 18.
  • FIG. 5 A second handle attachment is illustrated in FIG. 5.
  • the handle end 18 is equipped with an annular groove 21.
  • the stem end 18 is driven into the bore 14 of the hammer head 11, the free space in the bore 14 filled with a special adhesive 22. After the adhesive 22 has dried out, an optimal fit of the hammer head 11 on the handle 12 is ensured.
  • the steel sleeve 13 has the same structure as the embodiment according to FIGS. 1-4. The same reference numerals have therefore been chosen for this. Even with the second handle attachment, the steel sleeve 13 is secured by additional cross pins 20 on the hammer head 11 or on the handle end 13.
  • Fig. 6 shows a third handle attachment.
  • the bearing eye in the hammer head 11 is designed as a blind hole 23.
  • the handle end 18 provided with the steel sleeve 13 is driven into the blind hole 23.
  • a ring wedge 19 is driven into the head of the handle end 18.
  • the ring wedge 19 is completely driven into the handle end 18 when the bottom of the blind hole is touched.
  • the head of the handle end 18 is spread, whereby a firm seat of the handle 12 in the hammer head 11 is effected.
  • the hammer head 11 is still secured to the handle 12 by dowel pins 20.
  • the illustrated embodiments are only examples of realizations of the invention. This is not limited to this. Various modifications and applications are still possible within the scope of the invention.
  • the inner surfaces of the steel sleeve 13 could be equipped with barb-shaped projections which claw into the lateral surfaces of the stem 12 when the stem end 18 is introduced.
