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.
Claims22
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.
