Abstract

A slip grab ratchet binder with a primary hook having an enlarged diameter portion at a tip. A grab hook has an eyelet for sliding over the primary hook from a proximal end to the tip where it is obstructed from sliding off the primary hook. The grab hook and primary hook work in combination in a ratchet binder device to provide a slip grab ratchet binder for attaching to various hook points.

Claims (38)

1. A slip grab ratchet binder comprising:

an internally threaded tube having opposing, open ends;

threaded shafts threadably inserted into the opposing open ends, the threads in the tube and the threads on the shafts adapted to provide common contraction and extension of the shafts relative to an interior of the tube with the shafts not turning and the tube turning, the threaded shafts having a proximal end received in the tube;

a gear fixed to an exterior of the tube including gear teeth and a pawl and pawl housing mounted over the gear and pivotal around the gear, said pawl selectively engaging the gear teeth and preventing relative rotation of the housing in a selective one of the rotative directions;

a handle extended from said housing to provide leverage for an operator to pivot the housing with the pawl engaging the gear of the tube for forced rotation of the tube relative to the shafts;

at least one of the threaded shafts having a primary hook at a distal end disposed opposite from the proximal end, the primary hook having a tip and having an enlarged diameter portion at or near the tip;

a grab hook having an eyelet at one end, the eyelet sized to receive at least one of the shafts therethrough;

wherein the grab hook is configured to slide over the proximal end of the shaft and to slide over the primary hook until the grab hook reaches the enlarged diameter of the primary hook where it is obstructed from sliding any farther.

2. The slip grab ratchet binder of claim 1 , wherein the grab hook is smaller than the primary hook on the at least one shaft.

3. The slip grab ratchet binder of claim 1 , wherein the primary hook is formed integrally on the at least one shaft.

4. The slip grab ratchet binder of claim 1 , wherein the grab hook is configured for connecting to a chain or other small diameter hook point.

5. The slip grab ratchet binder of claim 1 , wherein the enlarged diameter portion is formed in the shape of an oval.

6. The slip grab ratchet binder of claim 1 , wherein the grab hook is sized such that it slides completely off of the at least one shaft at the proximal end.

7. The slip grab ratchet binder of claim 1 , wherein a gap of the grab hook is smaller than a gap of the primary hook on the at least one shaft.

8. A slip grab ratchet binder comprising:

an internally threaded tube having opposing, open ends;

threaded shafts threadably inserted into the opposing open ends, the threads in the tube and the threads on the shafts adapted to provide common contraction and extension of the shafts relative to an interior of the tube with the shafts not turning and the tube turning, the threaded shafts having a proximal end received in the tube;

means for preventing rotation of the tube relative to the shafts in a selective one of the rotative directions;

means for forcing rotation of the tube relative to the shafts in a selective one of the rotative directions;

at least one of the threaded shafts having a primary hook at a distal end disposed opposite from the proximal end, the primary hook having a tip and having an enlarged diameter portion at or near the tip;

a grab hook having an eyelet at one end, the eyelet sized to receive at least one of the shafts therethrough;

wherein the grab hook is configured to slide over the proximal end of the shaft and to slide over the primary hook until the grab hook reaches the enlarged diameter of the primary hook where it is obstructed from sliding any farther.

9. The slip grab ratchet binder of claim 8 , wherein the grab hook is smaller than the primary hook on the at least one shaft.

10. The slip grab ratchet binder of claim 8 , wherein the primary hook is formed integrally on the at least one shaft.

11. The slip grab ratchet binder of claim 8 , wherein the grab hook is configured for connecting to a chain or other small diameter hook point.

12. The slip grab ratchet binder of claim 8 , wherein the enlarged diameter portion is formed in the shape of an oval.

13. The slip grab ratchet binder of claim 8 , wherein the grab hook is sized such that it slides completely off of the at least one shaft at the proximal end.

14. The slip grab ratchet binder of claim 8 , wherein a gap of the grab hook is smaller than a gap of the primary hook on the at least one shaft.

15. A slip grab ratchet binder comprising:

an internally threaded tube having opposing, open ends;

threaded shafts threadably inserted into the opposing open ends, the threads in the tube and the threads on the shafts adapted to provide common contraction and extension of the shafts relative to an interior of the tube with the shafts not turning and the tube turning, the threaded shafts having a proximal end received in the tube;

a gear fixed to an exterior of the tube including gear teeth and a pawl and pawl housing mounted over the gear and pivotal around the gear, said pawl selectively engaging the gear teeth and preventing relative rotation of the housing in a selective one of the rotative directions;

a handle extended from said housing to provide leverage for an operator to pivot the housing with the pawl engaging the gear of the tube for forced rotation of the tube relative to the shafts;

at least one of the threaded shafts having a primary hook at a distal end disposed opposite from the proximal end, the primary hook having a tip and having an enlarged diameter portion at or near the tip;

a grab hook having an eyelet at one end, the eyelet sized to receive at least one of the shafts therethrough;

wherein the grab hook is configured to slide over the proximal end of the shaft and to slide over the primary hook until the grab hook reaches the enlarged diameter portion of the primary hook where it is obstructed from sliding any farther;

wherein the grab hook is smaller than the primary hook; and,

wherein the grab hook is configured to connect to a chain or other smaller diameter hook point.
