Abstract
A wrench for engaging a workpiece comprises a pair of fixed jaws and a pair of movable jaws being movable relative to the pair of fixed jaws. The workpiece includes a plurality of flats which may be adjoined at a plurality of corners. The pairs of fixed and movable jaws may be configured to engage the workpiece in at least one of a flat engaging position and a corner engaging position. The flat engaging position comprises the pairs of fixed and movable jaws being engaged to one of the flats on each one of the opposing sides of the workpiece. The corner engaging position comprises the pairs of fixed and movable jaws being engaged to an adjacent pair of the flats on each one of the opposing sides of the workpiece.
Claims17
A wrench for engaging a workpiece having a plurality of flats, the wrench comprising:
- a head portion, including:
- a pair of fixed jaws;
- and a pair of movable jaws being limited to movement in a lateral direction relative to the pair of fixed jaws, the pairs of fixed and movable jaws being configured to engage the workpiece in at least one of a flat engaging position and a corner engaging position;
- a sliding mechanism for coupling the pairs of fixed and movable jaws, the sliding mechanism including respective identical web grooves formed within a movable jaw web and a fixed jaw web, each of said web including respective fixed and movable bosses, the mechanism further including a shaft extended through the bosses;
- the flat engaging position comprising the pairs of the fixed and movable jaws being engageable to one of the flats on each one of opposing sides of the workpiece;
- and
- the corner engaging position comprising the pairs of the fixed and movable jaws being engageable to an adjacent pair of the flats on each one of the opposing sides of the workpiece.
A wrench for engaging a workpiece having a plurality of flats, the wrench comprising:
- a head portion, including:
- a pair of fixed jaws;
- and
- a pair of movable jaws being limited to movement in a lateral direction relative to the pair of fixed jaws, the pairs of fixed and movable jaws defining a wrench opening configured to engage the workpiece in a corner engaging position and preventing engagement of the workpiece in a flat engaging position;
- the comer engaging position comprising the pairs of the fixed and movable jaws being engageable to an adjacent pair of the flats on each one of opposing sides of the workpiece;
- the flat engaging position comprising the pairs of the fixed and movable jaws being engageable to one of the flats on each one of the opposing sides of the workpiece;
- wherein:
- the pair of fixed jaws comprises opposing first and second fixed jaws disposed in spaced relation to one another and respectively including inner and outer fixed lobes disposed in staggered relation to one another;
- the pair of movable jaws comprising opposing first and second movable jaws disposed in spaced relation to one another and respectively including inner and outer movable lobes disposed in staggered relation to one another;
- and
- the wrench opening being defined by the outer fixed lobe and inner movable lobe on one side of the wrench opening and the inner fixed lobe and outer movable lobe on an opposite side of the wrench opening.
A wrench for engaging a fastener having a plurality of flats adjoined at a plurality of comers, the wrench comprising:
- a fixed jaw set having opposing first and second fixed jaws respectively including inner and outer fixed lobes;
- and
- a movable jaw set being laterally movable relative to the fixed jaw set and having opposing first and second movable jaws respectively including inner and outer movable lobes;
- the fixed and movable jaw sets being configured to engage the fastener in at least one of a flat engaging position and a corner engaging position;
- the flat engaging position comprising:
- the inner fixed lobe and outer movable lobe being engageable to a single one of the flats on one of opposing sides of the wrench opening;
- the outer fixed lobe and inner movable lobe being engageable to a single one of the flats on a side of the wrench opening opposite the inner fixed lobe and outer movable lobe;
- the comer engaging position comprising:
- the inner fixed lobe and outer movable lobe being engageable to respective ones of a pair of the flats adjoined by one of the comers on one of the opposing sides of the wrench opening;
- and
- the outer fixed lobe and inner movable lobe being engageable to respective ones of a pair of the flats adjoined by one of the comers on a side of the wrench opening opposite the inner fixed lobe and outer movable lobe.
