Abstract

Trigger activated tools are provided that have one or more activation lockouts. The activation lockouts include electrical resets, variable position lockouts, mechanical lockouts, shield lockouts, and any combinations thereof.

First claim

What is claimed is:

1. A trigger activated tool, comprising:
an activatable device including a power source;
a handle portion having an activation trigger and a drain trigger both depending from a common pivot axis; and
a trigger lock slideably received in the activation trigger, the trigger lock being slideable between a locked position and the unlocked position,
wherein the activation trigger is movable about the common pivot axis between a normal position in which the power source is not in communication with the activatable device and an activated position in which the power source is in communication with the activatable device,
wherein the trigger lock, when in the locked position, prevents movement of the activation trigger to the activation position and, when in the unlocked position, allows movement of the activation trigger to the activation position,
wherein the drain trigger is movable about the common pivot axis between a normal position and a drain position in which potential energy within the activatable device is relieved, and
wherein the drain trigger is configured to move to the drain position when the trigger lock is in both the locked and unlocked positions.

2. The trigger activated tool of claim 1 , wherein the trigger lock is normally biased to the locked position and the activation and drain triggers are normally biased to the normal positions.

3. The trigger activated tool of claim 1 , wherein the trigger lock, when in the locked position, contacts an interior of the handle portion.

4. The trigger activated tool of claim 1 , wherein the trigger lock, when in the locked position, contacts an external portion of the handle portion.

5. The trigger activated tool of claim 1 , wherein the handle portion is an inline grip.

6. The trigger activated tool of claim 1 , wherein the handle portion is a pistol grip.

7. A trigger activated tool, comprising:
a jaw;
a power source;
a hydraulic unit operatively connected with the jaw;
a handle portion having an activation trigger and a drain trigger both depending from a common pivot axis; and
a trigger lock secured in the activation trigger for sliding movement in the activation trigger between a locked position and an unlocked position
the activation trigger being configured to move about the common pivot axis between a normal position and an activated position, the activation trigger, when in the activated position, placing the hydraulic unit in electrical communication with the power source such that the hydraulic unit activates the jaw,
the drain trigger being configured to move about the common pivot axis between a normal position and a drain position, the drain trigger, when in the drain position, relieving potential energy within the hydraulic unit, and
wherein the trigger lock, when in the locked position, providing a mechanical interference to prevent movement of the activation trigger to the activated position and, when in the unlocked position, allowing movement of the activation trigger to the activated position, and
wherein the drain trigger is configured to move between the normal position and the drain position when the trigger lock is in both the locked and unlocked positions.

8. The trigger activated tool of claim 7 , wherein the handle portion is an inline grip.

9. The trigger activated tool of claim 7 , wherein the handle portion is a pistol grip.

10. The trigger activated tool of claim 7 , wherein the mechanical interference is internal to the handle portion.

11. The trigger activated tool of claim 7 , wherein the mechanical interference is external to the handle portion.

12. The trigger activated tool of claim 7 , wherein the jaw comprises a crimping jaw.

13. The trigger activated tool of claim 7 , wherein the jaw comprises a cutting jaw.
