Abstract
A stake removal tool configured for removing in-ground stakes, the stake removal tool comprising an elongated member defining a proximal end and a distal end, a carriage, and a lift system configured to drive the carriage along a longitudinal direction of the elongated member. The carriage comprises a chassis and a pivoting member configured to pivot about a fulcrum and defining first and second engagement members. As the lift system engages the carriage to displace it downwardly in a longitudinal direction of the elongate member, the first and second pivot members may be forced to pivot thereby engaging and dislodging a stake.
Claims21
A stake removal tool configured for removing in-ground stakes, the stake removal tool comprising:
- an elongated member defining a first end portion and a second end portion;
- a carriage comprising a stake engagement assembly configured to engage and grasp the stake;
- a lift system configured to drive the carriage along a longitudinal direction of the elongated member;
- a carriage disengagement member comprising a non-threaded axle portion for disengaging the driven carriage from the lift system before the carriage reaches the first end portion of the elongated member;
- and
- a carriage engagement member comprising:
- a resilient member for moving the disengaged carriage toward the lift system;
- a threaded portion for threadingly engaging the carriage.
A method for removing a stake from a surface, the method comprising:
- driving a carriage downward toward the stake along an elongated member;
- disengaging the carriage from the elongated member upon reaching a non-threaded end portion of the elongated member;
- inserting the stake into an opening of an attachment member of the carriage;
- moving the disengaged carriage to be engaged to a threaded portion of the elongated member;
- and
- driving the engaged carriage upward to grasp the stake with the attachment member.
