Definitions

  • the invention relates to a tool booklet, consisting of a booklet body with a central longitudinal bore for receiving a tool shank, and with a collar formed at the front end and an adjoining, concavely profiled zone, at the end opposite the collar of which there is a double-conical section with a square cross section. ⁇ t.
  • Such a tool booklet is known from DE-B 2 452 302.
  • This known tool booklet is to be used in particular in connection with screwdrivers. It has an approximately central constriction, which is designed in a round cross section. Fingers of an operating hand resting in this area, however, cannot transfer torque well to the tool handle due to the resulting smooth surface of this round constriction. H. the tool booklet can slip in the operating hand.
  • the known tool In its upper handle part opposite the tool shank, the known tool is equipped with a ridge from which the gripping surfaces are inclined, in a straight line. This means that the ridge is relatively sharp, which should be noticeable in the operating hand.
  • the invention has for its object to design a tool book so that it is universal for a variety of tools such.
  • the collar and the concavely profiled zone have a round cross-section
  • the cross-sectional area of the tooling has a square cross-section over its entire length from the end of the concavely profiled zone up to and including the double-conical section
  • the double -conical section consists of two conical areas, the transition of which is rounded with a large radius. Due to this advantageous embodiment, the tool booklet according to the invention is not only suitable in connection with screwdrivers.
  • the main advantage of the tool booklet according to the invention is thus the universal shape, which is not only determined by one tool, but also by a multitude of hand tools of all kinds, but nevertheless does justice to all types of manual drive in such a way that a high torque or torque is obtained when pulling, turning or pressing A high force can be transmitted without causing a feeling of pain in the closed hand, so that pressure points are also avoided with prolonged use.
  • An inventive Tool handle consists of a stapler body 1 ° at its front end, the one to be used tool is turned towards the shaft, has a cylindrical collar. 2
  • the tacking body 1 has a central longitudinal bore 3 for receiving the tool shank.
  • a concave profiled cylinder zone 4 adjoins the collar 2.
  • the end 5 of the cylinder zone 4 opposite the collar 2 preferably has a larger diameter than the collar 2. From the end 5 there is formed a sloping zone 6, rounded off with a large diameter, which merges into a first rising cone region 7 of a double-conical section 8, and with a large rounding diameter.
  • the rear end area of the tack body 1 is formed by a sloping second cone area 9 of the double-conical section 8.
  • the cross-sectional area of the tack body 1 is always square from the end 5 to the rear end face 10, the four longitudinal edges 11 or the corners of the cross-sectional area being rounded off are.
  • the transition 12 of the two cone regions 7, 9 has the largest cross-sectional area, so that the stitching body becomes thicker from the front to the transition 12 as a whole.
  • the edge length of the square cross-sectional area at the transition 12 is advantageously approximately 25% more. than at the end 5 of the concave cylinder zone 4, and the edge length of the cross-sectional area at the end 5 is about 10% larger than the diameter of the collar 2.
  • the lengths of the individual areas or sections are dimensioned such that the areas, the falling zone 6 and the first cone area 7, together being longer overall than the cylinder zone 4 or the cone area 9.
  • the cone area 9 is shorter than the cylinder zone 4.
  • the falling zone 6 and the first cone area 7 are together about 15% longer than the cylinder zone 4, and the cone area 9 is about 15% shorter than the cylinder zone 4.
  • a contour of the tool handle is achieved by the square cross section of the handle body 1 behind the cylinder zone 4, which is optimally adapted to the shape of a closed hand, whereby the tool handle according to the invention in particular as a tool handle for creaking and turning crank is suitable.
