ABSTRACT:
An adjustable vise includes a toggle plier having first and second handles pivotally joined together to move relative to one another, a fixed jaw mounted to extend upwardly from one end of the first handle, a mounting bar pivotally joining the handles together and extending laterally in one direction from the handles generally perpendicular thereto, and a moveable jaw mounted on the bar to slide therealong and to extend upwardly to a spaced-apart position from the fixed jaw so that when the handles are moved apart, the jaws are caused to move away from one another and when the handles are moved together, the jaws are caused to move toward one another. A locking mechanism is mounted on the moveable jaw and is operable to selectively lock the moveable jaw in place on the mounting bar to thereby prevent sliding movement of the moveable jaw, or to unlock the moveable jaw from the mounting bar to allow sliding movement with respect thereto. The moveable jaw includes a channel through which the mounting bar may be inserted, at least a portion of the channel being shaped to define a wedge-shaped void between a wall of the channel and the mounting bar. The locking mechanism includes a foot having a wedge-shaped section disposable in the channel void and moveable between a first position in which the wedge-shaped section of the foot is in locking contact with the slide bar and the wall of the channel to prevent sliding of the moveable jaw, and a second position in which the wedge-shaped section of the foot is out of contact with the channel wall to allow sliding of the moveable jaw.
