Abstract

A pruning lopper with an adjustable attachment mechanism to provide for versatile cuts of tree branches and shrubs. The attachment mechanism is a ball joint that can rotate in an x-direction, a y-direction, around the axis of rotation of the pole, or any combination of the three. A pulley system internal to the pole prevents entanglement with tree branches while in operation.

Claims

1. A pruning lopper comprising:

a pole having a first end and a second end and an axis of rotation;

a lopping head located at the second end of the pole; and

an attachment mechanism attaching the lopping head to the second end of the pole, so that the lopping head is capable of rotating in at least two degrees of freedom relative to the axis of rotation of the pole.

2. The pruning lopper of claim 1, wherein the attachment mechanism is capable of rotating in three degrees of freedom relative to the axis of rotation of the pole.

3. The pruning lopper of claim 1, wherein the attachment mechanism comprises a ball joint.

4. The pruning lopper of claim 1, further comprising a leveraging system located substantially within the interior of the pole.

5. The pruning lopper system of claim 4, wherein the leveraging system is a pulley system comprising:

a fixed pulley block;

a movable pulley block; and

a cord with a first end and a second end, the cord connecting the fixed pulley block to the movable pulley block.

6. The pruning lopper of claim 5, wherein the first end of the cord is secured to a first fixed point located on the exterior of the pole and the second end of the cord is secured to a second fixed point located at the first end of the pole.

7. The pruning lopper of claim 6, wherein the second fixed point is on a pull ring detachable from the pole.

8. The pruning lopper of claim 6, wherein the first fixed point is located on a pull grip that slides along the pole.

9. The pruning lopper of claim 4, wherein the lopping head comprises a fixed blade and a movable blade.

10. The pruning lopper of claim 9, further comprising a cable with a first end and a second end, the first end attached to the movable blade and the second end attached to the leveraging system located within the pole.

11. The pruning lopper of claim 10, wherein the attachment mechanism comprises a ball joint, and the cable passes through the ball of the ball joint at an angle substantially perpendicular to the surface of the ball.

12. A pruning lopper comprising:

a pole housing having a first end and a second end;

a telescoping pole having a first end and a second end and an axis of rotation, wherein the first end of the telescoping pole is located within the pole housing at the second end of the pole housing;

a lopping head located at the second end of the telescoping pole; and

an attachment mechanism attaching the lopping head to the second end of the telescoping pole, so that the lopping head is capable of rotating in at least two degrees of freedom relative to the axis of rotation of the telescoping pole.

13. The pruning lopper of claim 12, wherein the attachment mechanism is capable of rotating in three degrees of freedom relative to the axis of rotation of the telescoping pole.

14. The pruning lopper of claim 12, wherein the attachment mechanism comprises a ball joint.

15. The pruning lopper of claim 12, further comprising a pulley system located substantially within the interior of the telescoping pole, comprising:

a fixed pulley block;

a movable pulley block; and

a cord with a first end and a second end, the cord connecting the fixed pulley block to the movable pulley block.

16. The pruning lopper of claim 15, wherein the first end of the cord exits the upper telescoping pole and secures to a fixed point located at the first end of the pole housing.

17. The pruning lopper of claim 16, further comprising a pull grip that slides along the exterior of the pole housing, the pull grip having a cleat that connects the pull grip to the cord.

18. The pruning lopper of claim 15, wherein the lopping head comprises a fixed blade and a movable blade.

19. The pruning lopper of claim 18, further comprising a cable with a first end and a second end, the first end attached to the movable blade and the second end attached to the pulley system within the telescoping pole.

20. The pruning lopper of claim 18, wherein the attachment mechanism comprises a ball joint, and the cable passes through the ball of the ball joint at an angle substantially perpendicular to the surface of the ball.
