Ratcheting adjustable wrench

A ratcheting wrench comprising:

• a handle pivotably connected a first jaw;
• a second jaw adjustably mounted relative to the first jaw;
• the pivoting of the handle relative to the first jaw moves the second jaw towards and away from the first jaw and engages a locking mechanism that locks the second jaw in position relative to the first jaw;
• said locking mechanism comprising a first link pivotably connected to said handle at a first pivot and to a cassette at a second pivot, said cassette being movably mounted on said first jaw wherein as the locking mechanism locks the second jaw in position relative to the first jaw, the second jaw is moved closer to the first jaw and at least one of said first link and cassette deflect thereby increasing the force exerted by the jaws.

A wrench comprising:

• a handle pivotably connected to a first jaw and having at least one tooth formed thereon;
• a second jaw adjustably mounted relative to the first jaw;
• a ratchet bar supporting the second jaw and having a second set of teeth formed thereon, said at least one tooth engaging said second set of teeth;
• the pivoting of the handle relative to the first jaw moves the second jaw towards and away from the first jaw.

A wrench comprising:

• a handle pivotably connected to a first jaw and having at least one first tooth formed thereon;
• a second jaw adjustably mounted relative to the first jaw;
• a ratchet bar supporting the second jaw and having at least one second tooth formed thereon, said at least one first tooth engaging said at least one second tooth;
• the pivoting of the handle relative to the first jaw moves the second jaw towards and away from the first jaw.

A ratcheting wrench comprising:

• a handle pivotably connected a first jaw;
• a second jaw;
• a drive mechanism for adjusting the distance between the first jaw and the second jaw along a first direction;
• a locking mechanism that locks the second jaw in position relative to the first jaw when said handle is pivoted in a first direction, said locking mechanism comprising a first link being pivotably connected to said handle at a first pivot and to a cassette at a second pivot, said cassette being mounted to said drive mechanism wherein said first link occupies a position when in a locked position where a line between said first pivot and said second pivot is generally parallel to said first direction but at a slight angle relative to said first direction whereby a backdrive force on the jaws tends to pivot said link away from said first direction.
