Definitions

  • the present invention relates to multi-bit tools, and more particularly to ratcheting multi-bit tools.
  • Multi-bit tools such as screwdrivers
  • screwdrivers have been widely available to the public for many years.
  • Multi-bit tools provide a convenient means for having various types of working bits readily available for use.
  • Previously types of multi-bit tools have removable and replaceable working bits that are typically are stored in the handle of the driver.
  • the working bits may be manually inserted one at a time, as selected, in an in-use position into a bit chuck at the front of the driver, or alternatively may be inserted into an extension member that is itself inserted into the open front end of the bit chuck.
  • ratchet mechanism For increased convenience in terms of turning of threaded fasteners by a handheld driver, it is known to include a ratchet mechanism in multi-bit tools having removable and replaceable working bits.
  • the ratchet mechanism is operatively disposed between the bit chuck and the main body of the driver. The rotational direction of ratcheting of the ratchet mechanism is selectable for turning threaded fasteners either clockwise or counter-clockwise.
  • ratchet mechanism For the multi-bit tools having removable and replaceable working bits as described above, the inclusion of a ratchet mechanism is quite straight forward. The longitudinal forces experienced by the driver during use, in reaction to pushing the driver onto a threaded fastener, are simply transmitted through the rachet mechanism to the handle.
  • the ratchet screwdriver includes a driving stem having a gear rotatably engaged in the bore of a handle and having a free end or engaging with a fastener to be driven.
  • a ratchet mechanism is engaged in the handle and engaged with the gear of the driving stem portion electively driving the driving stem.
  • a barrel is rotatably engaged on the driving stem and removable along the driving stem or engaging around the fastener and for preventing the fastener from being tilted and preventing the fastener from hurting the hand of the user.
  • More recent multi-bit tools include a plurality of bit assemblies, typically six bit assemblies, operatively mounted within the main body of the driver.
  • each bit assembly includes a working bit secured to some type of bit extension, to form an operational mechanism.
  • a manually operable actuation mechanism of some sort, possibly even a spring loaded actuation mechanism, is connected to the bit extension.
  • Each bit assembly is movable singularly, or in other words one at a time, between a retracted position within the main body of the driver and a forwardly extended in-use position whereat a working bit at the front end of bit assembly extends forwardly from the bit chuck of the driver for use.
  • each bit assembly when it is in its forwardly extended in-use position has a rearwardly facing surface that abuts in force transmitting relation against a generally forwardly facing surface that is either on the main body of the driver or on an internal part or portion of the driver, to thereby support the selected bit assembly in place during use.
  • United States patent 6,928,908 discloses a revolving screwdriver comprising a hollow handle with a ratchet device mounted thereon.
  • the ratchet device comprises a seat, a ratchet shaft and a knob.
  • a revolving cylinder is disposed within the hollow handle and includes a plurality of axial, peripheral cartridges. Each peripheral cartridge is capable of receiving a plurality of solid hexagonal shanks having a section of a hexagon.
  • a spring depressible ball in the handle is adapted to enter one of a plurality of recesses of the revolving cylinder for rotationally positioning a desired shank in alignment with the rear end.
  • a push rod is operated via pushing of the cap to readily move the selected solid shank out of the cartridge and into the rear end of the hollow ratchet shaft.

  • the indexing system 172 precludes the working bit 150 from freely turning to any rotational angle within the bit holder 164. Such free rotational turning of the working bit 150 is highly undesirable since the working bit 150 would have trouble rotationally lining up with the dodecagonally (twelve sided) shaped bit-receiving opening 131 in the bit chuck 130. Instead, the twelve positions of the indexing system 172 help rotationally align the working bit 150 with the dodecagonally (twelve sided) shaped bit-receiving opening 131 in bit chuck 130, while allowing the working bit 150 to have some rotational freedom, in case there is rotational mis-alignment with the bit-receiving opening 131.

  • the forwardly facing abutment surface 200 can alternatively be elsewhere within the handle 110.
  • any other suitable means 200 for selectively retaining a working bit 150 in the forwardly extended in-use configuration can be used.
  • the multi-bit tool 100 of the present invention further comprises a bi-directional rotation-locking mechanism 220 operatively interposed between the handle 110 and the bit chuck 130.
  • the bi-directional rotation-locking mechanism 220 comprises a bi-directional ratchet mechnism 220.
  • the first pawl portion 221 can engage the selector ring 224 to preclude movement of the handle 110 with respect to the bit chuck 130, in the first rotational direction "A". Accordingly, rotation or attempted of the handle 110 about the longitudinal axis "L" by the hand of a user, or by an automatic means in another embodiment, would cause corresponding rotation of the bit chuck 130 about the longitudinal axis "L", thereby permitting a threaded fastener to be turned.
  • the first pawl portion 221 permits movement of the handle 110 with respect to the bit chuck 130, in the second rotational direction "B". Accordingly, such rotation of the handle 110 about the longitudinal axis "L” by the hand of a user, or by an automatic means in another embodiment, would not cause corresponding rotation of the bit chuck 130 about the longitudinal axis "L", thereby precluding a threaded fastener from being turned.
