Abstract

A tool for providing a clamping force and a spreading force in the opposite direction of the clamping force. The tool includes a handle assembly having a trigger and a bar supported by the handle assembly. The bar is configured to move relative to the handle assembly when the trigger is actuated, and the bar includes a slot spanning from a first end of the bar to a second end of the bar. An inner rod is received within the slot, and a detent mechanism selectively couples the inner rod to the bar. The inner rod is received within the first end and coupled to the bar to provide the clamping force when the trigger is actuated, and the inner rod is received within the second end and coupled to the bar to provide the spreading force when the trigger is actuated.

First claim

What is claimed is:

1. A tool for providing a clamping force and a spreading force, the spreading force in an opposite direction of the clamping force, the tool comprising:
a handle assembly including a trigger;
a bar supported by the handle assembly and configured to move relative to the handle assembly when the trigger is actuated, the bar including a slot spanning from a first end of the bar to a second end of the bar;
an inner rod received within the slot; and
a detent mechanism operable to selectively couple the inner rod to the bar;
wherein the inner rod is received within the first end and coupled to the bar to provide the clamping force when the trigger is actuated, and wherein the inner rod is received within the second end and coupled to the bar to provide the spreading force when the trigger is actuated.

2. The tool of claim 1 , wherein the handle assembly includes a first jaw portion and the inner rod includes a second jaw portion.

3. The tool of claim 2 , wherein the first jaw portion includes a first workpiece-engagement surface, and the second jaw portion includes a second workpiece-engagement surface and a third workpiece-engagement surface.

4. The tool of claim 3 , wherein the first workpiece-engagement surface and the second workpiece-engagement surface are engaged when the tool is providing the clamping force.

5. The tool of claim 3 , wherein the first workpiece-engagement surface and the third workpiece-engagement surface are engaged when the tool is providing the spreading force.

6. The tool of claim 2 , wherein the first jaw portion includes a first workpiece-engagement surface and the second jaw portion includes a second workpiece-engagement surface, the second jaw portion rotatably coupled to the inner rod.

7. The tool of claim 1 , wherein the inner rod is completely separable from the bar.

8. The tool of claim 1 , wherein the detent mechanism includes a pivotable clip coupled to the bar, the pivotable clip configured to be at least partially received in a slot formed in the inner rod to selectively couple the inner rod to the bar.

9. The tool of claim 1 , wherein the detent mechanism includes a biased plunger coupled to the bar, the biased plunger configured to be at least partially received in an aperture formed in the inner rod to selectively couple the inner rod to the bar.

10. The tool of claim 1 , wherein the inner rod is adjustable relative to the bar to vary a span of the tool.

11. A tool comprising:
a handle assembly including an actuator;
a bar supported by the handle assembly and configured to move relative to the handle assembly when the actuator is actuated,
an inner rod coupled to the bar; and
a detent mechanism coupled to the bar and configured to selectively lock the inner rod to the bar;
wherein the inner rod is adjusted relative to the bar to vary a span of the tool;
wherein the bar includes a slot spanning from a first end of the bar to a second end of the bar; the inner rod is received within the first end and coupled to the bar to provide a clamping force, and wherein the inner rod is received within the second end and coupled to the bar to provide a spreading force.

12. The tool of claim 11 , wherein the span can be adjusted in both a clamping configuration and a spreading configuration.

13. The tool of claim 11 , wherein the detent mechanism includes a pivotable clip coupled to the bar, the pivotable clip configured to be at least partially received in a slot formed in the inner rod to selectively couple the inner rod to the bar.

14. The tool of claim 11 , wherein the detent mechanism includes a biased plunger coupled to the bar, the biased plunger configured to be at least partially received in an aperture formed in the inner rod to selectively couple the inner rod to the bar.

15. A hand tool comprising:
a handle assembly including a trigger;
a bar supported by the handle assembly and configured to move relative to the handle assembly when the trigger is actuated;
a telescoping inner rod adjustably coupled to the bar to vary a span of the tool and to switch the tool from a clamping configuration to a spreading configuration;
wherein the telescoping inner rod is coupled to a first end of the bar in the clamping configuration and coupled to a second end of the bar in the spreading configuration.

16. The hand tool of claim 15 , further including a detent mechanism operable to selectively lock the telescoping inner rod to the bar.

17. The hand tool of claim 15 , wherein the handle assembly includes a first jaw portion and the telescoping inner rod includes a second jaw portion.

18. The hand tool of claim 15 , wherein the telescoping inner rod is adjustable to provide at least four spans of the tool.
