Abstract

A probe bar remover (10) for loosening and removing probe bars from the ground includes an elongated member (12) with an engagement end and a handling end. The elongated member (12) also includes a foot plate (18) along the elongated member (12) oriented toward the handling end. A bar engagement member (20) is coupled to the elongated member (12) at the engagement end and can include an engagement gap (22) for engaging a probe bar (15). A fulcrum (24) can be oriented along the elongated member (12), which contacts a ground surface, and a handlebar (26) is removably coupled to the handling end of the elongated member. To remove probe bars from a ground surface, the probe bar remover (10) can be engaged with an exposed portion of a probe bar (15) and a downward force is exerted on the foot plate (18) so as to at least loosen the probe bar (15) from the ground.

Claims

1. A probe bar remover comprising:

a) an elongated member having an engagement end opposite a handling end and a foot plate oriented at the handling end, wherein the foot plate is a plate positioned above a top surface of the elongated member or is an integrated plate along a section of the elongated member;

b) a bar engagement member attached to the elongated member at the engagement end configured to rotationally bind and releaseably engage a probe bar;

c) a fulcrum disposed intermediate the elongated member having a fulcrum point that can contact a ground surface; and

d) an elongated handlebar removably coupled at the handling end and extending away from the elongated member.

2. A probe bar remover according to claim 1, wherein the fulcrum is a set of wheels.

3. A probe bar remover according to claim 2, further comprising a lock mechanism operatively associated with the wheels to prevent rotation.

4. A probe bar remover according to claim 1, wherein the foot plate is a plate affixed to the top surface of the elongated member.

5. A probe bar remover according to claim 1, wherein the bar engagement member includes an engagement gap for engaging the probe bar.

6. A probe bar remover according to claim 5, wherein the engagement gap is an open gap configured to engage a probe bar wherein one section of the gap is open when engaged with the probe bar.

7. A probe bar remover according to claim 6, wherein the bar engagement member is a fork having prongs oriented substantially perpendicular to the elongated member.

8. A probe bar remover according to claim 6, wherein the bar engagement member is an adjustable wrench head.

9. A probe bar remover according to claim 6, wherein the engagement member has teeth extending inwardly towards the open gap.

10. A probe bar remover according to claim 1, wherein the bar engagement member is pivotally attached to the elongated member.

11. A probe bar remover according to claim 1, wherein the elongated member is bent upwardly at an angle toward engagement end.

12. A probe bar remover according to claim 1, wherein the handlebar includes a length adjustment mechanism for variable adjustment of length.

13. A probe bar remover according to claim 12, wherein the length adjustment mechanism is a friction-fitting joint, a screw-fitting joint, or a slot-and-pin joint having multiple slot positions.

14. A probe bar remover according to claim 1, wherein the handlebar is collapsible such that the handlebar can be oriented substantially parallel to the elongated member for storage or transport.

15. A probe bar remover according to claim 1, wherein the handlebar pivots about the elongated member.

16. A probe bar remover according to claim 1, wherein the elongated member comprises light-weight materials.

17. A probe bar remover according to claim 1, wherein the probe bar remover weighs less than about 20 pounds.

18. A probe bar remover according to claim 1, wherein the probe bar remover weighs less than about 11 pounds.

19. A probe bar remover according to claim 1, further comprising a bar driver slidably coupled to the probe bar, and wherein the elongated member pivotally engages the probe bar so that the elongated member can be positioned either substantially parallel to the bar driver when the bar is being driven into the ground, or substantially perpendicular to the bar when the bar is being removed from the ground.

20. A method for removing probe bars from a ground surface comprising:

a) engaging an exposed portion of a probe bar with a probe bar remover;

the probe bar remover including an elongated member having an engagement end opposite a handling end and a foot plate oriented at the handling end, wherein the foot plate is a plate positioned above a top surface of the elongated member or is an integrated plate along a section of the elongated member;

a bar engagement member attached to the elongated member at the engagement end configured to rotationally bind and releaseably engage the probe bar;

a fulcrum intermediate the elongated member to contact a ground surface; and

a handlebar attached at the handling end; and

b) exerting a downward force on the foot plate such that the bar engagement member is forced upward sufficient to at least loosen the probe bar from the ground.

21. A method for removing probe bars from a ground surface according to claim 20, further comprising releasing the bar engagement member by moving the foot plate upward and repeating the step of exerting a downward force until the probe bar is loosened from the ground.

22. A method for removing probe bars from a ground surface according to claim 20, wherein exerting the downward force on the foot plate comprises exerting substantially all of the force sufficient to at least loosen the probe bar at the footplate.
