Definitions

  • the invention relates to a ratchet wrench according to the preamble of claim 1.
  • a ratchet wrench with two handle levers and two switching mechanisms which act on a common output axis. While one handle lever is used to guide the screwdriver or socket wrench that can be inserted into a square hole in the output axis, the other handle lever is used to rotate the same.
  • a screwdriver or socket wrench can be inserted at both ends of the square hole, so that depending on how the ratchet wrench is held, it is possible to tighten or loosen a screw. Tightening or loosening a screw is done by turning one of the handle levers in one direction while turning the handle back lever the rear derailleur unlocked the output shaft. So only half the movement of the handle lever is used.
  • US Pat. No. 2,808,749 describes a ratchet wrench with a rotatable shaft forming a drive shaft, to the end of which a driving bevel gear is fastened on the key head end.
  • This driving bevel gear meshes with a driven bevel gear on the output axis of the key, a switching mechanism being arranged between the output axis and the driven bevel gear.
  • the output shaft is only rotated in one direction in the drive direction when the key shaft is rotated, while the output shaft is unlocked when the key shaft is turned back.
  • only half the drive movement is used to tighten or loosen a screw.
  • the ratchet wrench is switched over to tightening or loosening a screw by pushing the end of the output shaft, which is displaceable in the longitudinal direction, toward one or the other side of the wrench.
  • the tool comprises a rotatable shaft, the outer surface of which is provided with a steep slope.
  • a sleeve-shaped body sits on the shaft and is controlled by the thread.
  • the shaft can be rotated by moving the sleeve.
  • the invention has for its object to provide a ratchet wrench that allows both One way umzuset as well as the movements of the drive shaft into a drive movement of the output shaft - zen, to thereby enable an efficient workflow.
  • the most important advantage of the invention can be seen that all rotary movements of the key shaft can be used to turn the output shaft.
  • the ratchet wrench according to the invention thus works significantly faster than the known keys.
  • the output shaft can be reversed by a back and forth swiveling movement, which makes handling easier in certain confined spaces.
  • the robustness of the ratchet wrench according to the invention can be regarded as a second advantage. This is due to the construction according to the invention, according to which the load is distributed symmetrically over the two driven bevel gears.
  • the ratchet wrench comprises a key head 1 and a key shaft 2.
  • an output shaft (driver) 3 is rotatably mounted in sleeves 5 and 6, which are supported on bearing surfaces 4.
  • the upper and lower ends of the sleeves 5, 6 carry bevel gears 7 and 8 and their inner surfaces are provided with an internal toothing 9 and 9 '.
  • the key head 1 is closed off on both sides by cover plates 15 and 16.
  • the output shaft 3 has the shape of a square in cross section.
  • a wedge-shaped incision 10 is formed in one side.
  • a locking block 11 or 11' is arranged, the outside of the toothing 9 or 9 'and the inside of which is adapted to the notch 10.
  • the locking block 11 or 11 ' is attached to a spring 12 which presses it against the teeth 9 or 9 °.
  • the drive shaft 18 of the key shaft 2 is mounted in the bearing 17 in the key head 1.
  • a bevel gear 19 is attached, with which both bevel gears 7 and 8 mounted in key head 1 mesh.
  • the drive shaft 18 is rotated, the two bevel gears 7, 8 are rotated by the bevel gear 19. 2, the bevel gear 7 or 8, which is rotated counterclockwise, is coupled to the output shaft 3. If the direction of rotation of the drive shaft 18 is changed, the other of the bevel gears mentioned is coupled together with the output shaft 3. Turning the drive shaft 18 in one direction or the other always has turning the output shaft 3 in the same direction, i.e. 2 in a counterclockwise direction.
  • the output shaft 3 is designed to be displaceable in the longitudinal direction. As a result, it can also be shifted into the position 3 'which is indicated by dash-dot lines in FIG. 1.
  • a steep thread 20 is cut into the outer surface of the drive shaft 18 of the key shaft 2.
  • a sleeve 21 with a pin 22 is arranged around the drive shaft 18.
  • the steep thread 20 causes the drive shaft 18 to rotate back and forth.
  • the output shaft 3 rotates constantly in the same direction.
  • 3 shows a second advantageous embodiment of the invention.
  • This embodiment has a completely identical key head 31 as the embodiment described above.
  • the key shaft 32 is designed as a drive shaft 38 which is bent at an angle of approximately 90 ° near the key head 31.
  • FIG. 4 shows a third embodiment of the invention, in which the advantages of the two previously described embodiments are combined.
  • This embodiment also has a key head 41 with the output axis ⁇ 43 of the type described above.
  • the drive shaft 48 mounted in the key head 41 corresponds in its construction to the drive shaft 18 according to FIG. 1, but a joint 51 is engaged in it near the key head 41.
  • a thread 50 is cut on the drive shaft 48 and a sleeve 40 with a pin 52 sliding in the thread is pushed.
  • the key can be used in the manner set forth in connection with FIGS. 1 and 2.
  • the drive shaft 48 can be angled at the joint 51, so that the Ratchet wrench can be used in the same way as in the previous embodiment.
  • the thread cut on the drive shaft 18 or 48 can alternatively also be cut on the sleeve 21 or 40.
