Definitions

  • the clamping UNITED STATES PATENTS means is removably engaged with the lever by means of plural notches to one of which a pin is engaged.
  • the present invention relates to a wrench used for removing or screwing a threaded body such as a replaceable oil filter, bolt, nut.
  • a new and improved wrench comprising a tightening means which has plural curved members pivotally connected to each other to form a substantially circular configuration, a lever which is pivotally connected by a pivot means to one end of the connected curved members, a clamping member which is pivotally connected to the other end of said connected curved members, and means for removably engaging said clamping member to said lever, said engaging means having plural notches and a pin engaged with one of said notches in accordance with a size of a threaded body.
  • FIG. I is a perspective view of a wrench according to a first embodiment of the present invention.
  • FIGS. 2:: and 2b are plane views of the wrench of the first embodiment, in which FIGS. 2a and 2b are adapted to threaded bodies having a larger diameter and a smaller diameter, respectively;
  • FIG. 3 is a perspective view of a wrench according to a second embodiment of the present invention.
  • FIG. 5 is a sectional view of line V-V in FIG. 4.
  • three metal-made curved members 2I, 2-2, 2-3 are pivotally connected to each other to form a substantially circular tightening means 4, one end of which is pivotally connected to an end of a lever 6 by a pin 7, and the other end of which is pivotally connected to a clamping member 8 by a pin 9.
  • the clamping member has three recesses or hooked notches Ila, 11b and 11c arranged substantially in parallel to each other along the lengthwise direction thereof. Each of the hooked notches 11 partially extends in the clamping member from the inner surface thereof toward the end opposite to the pin 9.
  • the pin 7 is provided at the top portion of the lever 6, and the pin 10 is provided at a portion of the lever lower than the pin 7.
  • pin 7 and the pin 10 may be contradictory located on the lever 6.
  • the pin 10 may be provided at the top of the lever in place of the pin 7. In this case, however, the lever is rotated in the direction opposite to that of the wrench shown in FIG. 2.
  • a threaded body such as bolt which is positioned at a recess or a concave 15 as shown well in FIG. 5 is held by the tightening plates.
  • This wrench is faborably applicable particularly to the threaded body positioned in the concave 15.
  • the tightening plate 13 has a number of grooves or teeth 1 on the inner sur face thereof to prevent sliding. The purpose of forming such teeth is as same as that of the first embodiment.
  • each of the tightening plates 13 may have a curved surface so that larger area of the plates 13 may be contacted with the threaded body, whereby a re moving or screwing operation can be done more effec tively.
  • the notches 11a, 11b, He may be provided along the lengthwise direction of the lever 6 while the pin 10 may be provided on the clamping member 8.
  • each of said curved members has an integral tightening plate extending vertically in both directions beyond a horizontal plane on which said curved members are located, said tightening plate having saws on an inner curved surface thereof,
  • each of said curved members has an integral inwardly extending flange portion and wherein each said flange portion at its inner end has one of the said tightening plates integrally connected thereto.
