Abstract
A clamping and/or spreading tool comprises a drive for displacement of a push or pull rod to which a movable jaw is fixed with respect to a support carrying a stationary jaw in longitudinal direction of the push and pull rod, the drive comprising a torsion spring and being adapted to enter torque transmitting engagement with the push or pull rod for displacement of the same.
Claims31
A bar clamp, comprising:
- a bar, the bar including a depression;
- a first jaw movably coupled to said bar;
- a second jaw being movably coupled to said bar;
- and
- a motor configured to move said second jaw toward said first jaw, one of said first and second jaws including a drive lever that engages said bar and a trigger to move said drive lever and move said bar relative to said one of said first and second jaws,
- wherein at least a portion of the motor extends within the depression.
3 more elements
A bar clamp, comprising:
- a bar, the bar including a depression;
- a first jaw movably coupled to said bar;
- a second jaw coupled to said bar;
- and
- a motor attached to said first jaw and attached to said bar and configured to move said bar toward said first jaw, one of said first and second jaws including a drive lever that engages said bar and a trigger to move said drive lever and move said bar relative to said one of said first and second jaws,
- wherein at least a portion of the motor extends within the depression.
3 more elements
A bar clamp, comprising:
- a first jaw;
- a bar being movably coupled to said first jaw, the bar including a depression;
- a second jaw being coupled to said bar;
- and
- a motor coupled to said first jaw and having a rotatable element, said motor moving said bar relative to said first jaw, said first jaw including a drive lever coupled to said bar and a trigger to move said drive lever and to move said bar relative to said first jaw,
- wherein at least a portion of the motor extends within the depression.
3 more elements
A method of using a bar clamp, comprising:
- positioning a first jaw and a second jaw on opposite sides of an item to be clamped, the first and second jaws being positioned on a bar, the bar including a depression;
- activating a rotating element of a motor to move the second jaw closer to the first jaw until the first and second jaws contact opposite sides of the item to be clamped;
- and
- activating a trigger to provide increased clamping of the first and second jaws against the sides of the item to be clamped,
- wherein at least a portion of the motor extends within the depression.
2 more elements
A clamp, comprising:
- a bar, the bar including a depression;
- a first jaw movably coupled to said bar;
- a second jaw coupled to said bar;
- a drive spring connected to said first jaw and configured to effect relative movement that draws said first and second jaws together;
- a brake lever engageable with said bar to prevent said drive spring from effecting relative movement that draws said first and second jaws together;
- a release member that releases said brake lever from engagement with said bar to enable said drive spring to effect relative movement that draws said first and second jaws together;
- and
- said first jaw including a drive lever that engages said bar and a trigger that moves said drive lever so as to effect relative movement that draws the jaws together,
- wherein at least a portion of the drive spring extends within the depression.
6 more elements
A method for operating a clamp, having a bar with a depression, a first jaw carried by the bar, and a second jaw carried by the bar, comprising:
- operating a motor to effect relative movement that draws the first and second jaws together;
- and after said operating of the motor, manually moving a trigger to operate a drive lever so as to draw the first and second jaws closer together,
- wherein at least a portion of the motor extends within the depression.
