Abstract
Embodiments of the invention provide a clevis pin arrangement for use in a tool. The clevis pin arrangement can include a clevis that includes a first and second leg with first and second apertures, respectively, a clevis pin that extends between the first and second apertures when in a closed position, and an actuator. The actuator can move the clevis pin arrangement between the closed position and an open position.
Claims14
A clevis pin arrangement for use in a tool, the clevis pin arrangement comprising:
- a clevis with a first leg having a first aperture and a second leg having a second aperture;
- a clevis pin moveable between a locked orientation and an unlocked orientation, the clevis pin having a first end, an intermediate portion including a stop slot that extends along the intermediate portion between the first end and a second end of the clevis pin, the first end extending into the first aperture and the intermediate portion extending through the second aperture while the clevis pin arrangement is in a closed position, the first end configured to be removed from the first aperture while in the unlocked orientation to provide an open position of the clevis pin arrangement;
- a stop pin disposed within the second aperture;
- a stop pin recess disposed in the clevis pin and configured to engage the stop pin, the stop pin recess extending entirely around the clevis pin;
- and
- an actuator configured to move relative to the clevis to selectively engage and disengage the stop pin with the stop pin recess and move the clevis pin arrangement between the locked orientation and the unlocked orientation, the stop pin disposed in the stop pin recess and positioned opposite the stop slot when the clevis pin is in the locked orientation.
A clevis pin arrangement for use in a tool, the clevis pin arrangement comprising:
- a clevis with a first leg having a first aperture and a second leg having a second aperture, the clevis including a stop pin aperture and a stop pin positioned in the stop pin aperture;
- a clevis pin having a first end, an intermediate portion, and a second end, the first end extending into the first aperture and the intermediate portion extending into the second aperture while in a closed position, the first end being removed from the first aperture while in an open position, the second end including a stop pin recess;
- and
- a clevis lever coupled to the clevis pin and engaging a spring, the clevis lever including a drive aperture receiving the second end of the clevis pin, a lever body, and an inner surface, the inner surface including a first detent and a second detent that engage the second leg in a closed position, the first detent disengaged from the second leg and the second detent engaged with the second leg in an intermediate position,
- rotation of the lever body causing the first detent to decompress away from the second leg and move the stop pin within the stop pin recess into the intermediate position,
- further rotation of the lever body causing the second detent to decompress away from the second leg and pull the clevis pin out of the first aperture into the open position, the lever body rotatable in both a first rotational direction and a second rotational direction that is opposite the first rotational direction to cause the stop pin to move from the closed position to the open position.
