Abstract

A ratchet mechanism for securing cargo that may include a body, a ratchet, a lever and an adjustable or extendable handle. The ratchet may include a pair of opposing arms connected to the body and a spool rotatably connected to the arms. The lever may be rotatably attached to the arms and reciprocated between an open position and a closed position, wherein the lever may include at least one pawl to engage the ratchet wheels and rotate the spool when the lever is reciprocated. The handle may be adjustable to increase the mechanical advantage of the lever. The handle may be rotatably connected to the lever to extend the length of the lever. The handle may be slidably connected to the lever, to slide between a compact position where the handle is closer to the spool, and an extended position where the handle extends further away from the spool.

Claims

1. A ratchet mechanism comprising:

a body configured to receive a strap;

a pair of opposing arms connected to said body;

a spool rotatably connected to said opposing arms, said spool configured to wind said strap;

at least one ratchet wheel connected to opposing ends of said spool;

a lever attached to said arms and reciprocated between an open position and a closed position, wherein said lever includes at least one pawl to engage said at least one ratchet wheel and rotate said spool when said lever is reciprocated; and

wherein said lever is extendable away from said spool to increase the mechanical advantage of said lever.

2. The ratchet mechanism of claim 1 further comprising a release mechanism capable of selectively disengaging said pawl from said ratchet wheel.

3. The ratchet mechanism of claim 2, wherein said release mechanism is connected to said lever.

4. The ratchet mechanism of claim 3, wherein said lever includes a handle rotatably connected to said lever.

5. The ratchet mechanism of claim 4, wherein said handle is rotatable between a first position, wherein said handle is located closer to said spool, and a second position, wherein said handle extends further away from said spool.

6. The ratchet mechanism of claim 5, wherein said release mechanism is connected to said lever.

7. The ratchet mechanism of claim 3, wherein said lever includes a handle slidably connected with said lever.

8. The ratchet mechanism of claim 7, wherein said handle is slidable between a first position, wherein said handle is closer to said spool, and a second position, wherein said handle extends further away from said spool.

9. A ratchet mechanism comprising:

a body configured to receive a strap;

a pair of opposing arms connected to said body;

a spool in rotatable engagement with said opposing arms, said spool capable of winding said strap;

a pair of ratchet wheels connected to opposing ends of said spool;

a lever attached to said arms and reciprocated between an open position and a closed position, wherein said lever includes at least one pawl to engage said ratchet wheels thereby rotating said spool when said lever is reciprocated; and

a handle having a first end rotatably connected to said lever and a second end capable of rotating about said first end to extend the length of said lever and increase the mechanical advantage of said lever.

10. The ratchet mechanism of claim 9, wherein said handle is rotatable between a compact position wherein said second end is closer to said spool, and an extended position, wherein said second end is extended further away from said spool.

11. The ratchet mechanism of claim 10 further comprising a pivot puck positioned between said handle and said lever, said puck capable of facilitating rotation of said handle.

12. The ratchet mechanism of claim 10, wherein said handle is lockable in said compact position.

13. The ratchet mechanism of claim 10, wherein said handle is lockable in said extended position.

14. The ratchet mechanism of claim 11, further comprising a release mechanism capable of selectively disengaging said pawl from said ratchet wheel.

15. A ratchet mechanism comprising:

a body configured to receive a strap;

a pair of opposing arms connected to said body;

a spool in rotatable engagement with said opposing arms, said spool capable of winding said strap;

a pair of ratchet wheels connected to opposing ends of said spool;

a lever attached to said arms and reciprocated between an open position and a closed position, wherein said lever includes at least one pawl to engage said ratchet wheels thereby rotating said spool when said lever is reciprocated; and

a handle slidably connected to said lever, said handle slidable between a compact position wherein said handle is closer to said spool, and an extended position wherein said handle extends further away from said spool.

16. The ratchet mechanism of claim 16, wherein said handle is lockable in said compact position and in said extended position.

17. The ratchet mechanism of claim 17 further comprising a release button to release said handle form said lockable positions.
