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.

Claims (37)

1 . A trigger activated tool, comprising:

a handle portion;

an activatable device including a power source;

an activation trigger depending from the handle portion, the activation trigger being configured for movement between a non-activated 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;

a drain trigger depending from the handle portion, the drain trigger being movable between a normal position in which hydraulic pressure is maintained in the activatable device and a drain position in which the hydraulic pressure is relieved from the activatable device; and

a guard depending from the handle portion, the guard pivots about a pivot point on the handle between a guarded position and an un-guarded position,

wherein the guard, when in the guarded position, is positioned with respect to the activation trigger to not allow the activation trigger to be moved to the activated position, but, when in the un-guarded position, is positioned with respect to the activation trigger to allow the activation trigger to be moved to the activated position, and

wherein the guard has a maximum position limiter at an end of the guard that is opposite the pivot point, the maximum position limiter includes an interference structure that catches or abuts a portion of the tool that is internal to the handle portion to limit a maximum rotation of the guard in the unguarded position.

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

3 . The trigger activated tool of claim 2 , wherein the guard is a swivel guard.

4 . The trigger activated tool of claim 3 , wherein the swivel guard further comprises a spring that biases the swivel guard to the guarded position.

5 . The trigger activated tool of claim 3 , wherein the swivel guard defines an opening below the activation and drain triggers, wherein the opening provides an area below the activation and drain triggers.

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

7 . The trigger activated tool of claim 6 , wherein the guard is a pivot guard.

8 . The trigger activated tool of claim 1 , wherein the activatable device comprises a jaw and a hydraulic drive unit operatively connected with the jaw.

9 . The trigger activated tool of claim 8 , wherein the power source is a battery.

10 . The trigger activated tool of claim 8 , wherein the jaw comprises a crimping jaw or cutting jaw.

11 . The trigger activated tool of claim 1 , further comprising an electrical reset lockout having a locked state and an unlocked state and a control circuit in communication with the electrical reset lockout, wherein the electrical reset lockout is configured so that, regardless of whether the activation trigger is in the activated or non-activation position, the electrical reset lockout prevents activation of the activatable device unless the electrical reset lockout is in the unlocked state.

12 . The trigger activated tool of claim 11 , wherein the control circuit provides a predetermined time period after movement of the electrical reset lockout to the unlocked state during which movement of the activation trigger from the non-activated position to the activated position activates the activatable device.

13 . The trigger activated tool of claim 11 , wherein the electrical reset lockout prevents activation of the tool without simultaneous movement of the activation trigger to the activated position and changing of the electrical reset lockout to the unlocked state.

14 . The trigger activated tool of claim 11 , wherein the handle portion comprises a pistol style grip, and wherein the electrical reset lockout is positioned on an upper wall of the pistol style grip.

15 . The trigger activated tool of claim 11 , wherein the handle portion comprises a pistol style grip, and wherein the electrical reset lockout is positioned on a side wall of the pistol style grip.

16 . The trigger activated tool of claim 11 , wherein the handle portion comprises a pistol style grip, and wherein the electrical reset lockout is positioned on both opposite side walls of the pistol style grip.

17 . The trigger activated tool of claim 11 , wherein the control circuit comprises a solid state circuit, a digital circuit, hardware, software, and any combinations thereof.

18 . The trigger activated tool of claim 11 , wherein the control circuit is programmable by a user.

19 . The trigger activated tool of claim 11 , further comprising a three-position switch that includes the activation trigger and the drain trigger.

20 . The trigger activated tool of claim 19 , wherein the electrical reset lockout is positioned on the handle portion of the inline grip between the three-position switch and the jaw.

21 . A trigger activated tool, comprising:

a handle portion;

an activation trigger depending from the handle portion, the activation trigger being configured for movement between a non-activated position and an activated position;

a drain trigger depending from the handle portion, the drain trigger being movable between a normal position and a drain position; and

a guard depending from the handle portion, the guard pivots about a pivot point on the handle between a guarded position and an un-guarded position,

wherein the guard includes an interference structure that catches or abuts a portion of the tool that is internal to the handle portion to limit a maximum rotation of the guard in the unguarded position,

wherein the guard, when in the guarded position, is positioned with respect to the activation trigger to not allow the activation trigger to be moved to the activated position,

wherein the guard, when in the un-guarded position, is positioned with respect to the activation trigger to allow the activation trigger to be moved to the activated position, and

wherein the interference structure depends from the guard at a position between the pivot point and an end of the guard that is opposite the pivot point.

22 . The trigger activated tool of claim 21 , wherein the interference structure depends from the guard at a position remote from the pivot point.
