Abstract

A multi-purpose trucker'"'"'s power puller tool with a hook rod that slides in the bore of a handle, and a weighted head at an end of the handle. The weighted head provides momentum to the hooked end for yanking free stuck objects, such as a truck'"'"'s fifth wheel pin. The slidable rod also allows the tool to be locked in extended or collapsed positions. The invention also allows interchangeable hook rods to be used, so that the tool may be adapted to different purposes, such as grabbing and pulling eyelets of truck load covers, or pulling chains.

Claims

1. A trucker'"'"'s multi-purpose puller tool comprising:

an elongated hollow cylindrical handle having an open end, a head end, and an elongated handle portion between the open end and the head end,

a heavy hammer head mounted transversely at the head end of the handle,

an elongated hook rod slidably received in the open end of the elongated hollow cylindrical handle, the hook rod further comprising a hook end, a distal end, and an elongated rod portion between the hook end and the distal end,

a stop nut connected to the distal end of the hook rod, and

a lock nut at the open end of the handle, the lock nut further comprising a bore slidably receiving the elongated rod portion of the hook rod, a chamber and a stopping face within the chamber, wherein the stopping face is sized to receive and stop the stop nut of the hook rod.

2. The trucker'"'"'s multi-purpose puller tool of claim 1 further comprising a wedge lock sized to fit within the chamber of the lock nut at the stopping face, wherein the wedge lock further comprises a bore to receive and squeeze the rod portion of the hook rod.

3. The trucker'"'"'s multi-purpose puller tool of claim 2 wherein the open end of the handle has external threads and the lock nut is threadably received by the external threads of the handle, and wherein the bore of the wedge lock is progressively squeezed against the rod portion of the hook rod when the lock nut is threaded onto the external threads of the handle.

4. The trucker'"'"'s multi-purpose puller tool of claim 1 wherein the hook end of the hook rod is a crook.

5. The trucker'"'"'s multi-purpose puller tool of claim 1 wherein the hook end of the hook rod is a right angle hook.

6. The trucker'"'"'s multi-purpose puller tool of claim 1 wherein the hook end of the hook rod is an acute angle hook.

7. The trucker'"'"'s multi-purpose puller tool of claim 1 wherein the handle portion of the elongated hollow cylindrical handle has an external surface, and wherein the external surface comprises a knurled gripping portion.

8. The trucker'"'"'s multi-purpose puller tool of claim 1 wherein the transverse hammer head has an external surface, and wherein the external surface of the hammer head comprises a knurled gripping portion.

9. A multi-purpose puller tool comprising:

a hollow cylindrical handle having an open end, a head end, and a handle portion between the open end and the head end,

a metal head at the head end of the handle,

a rod received by the open end of the hollow cylindrical handle, the rod further comprising a hook end forming a hook, a stop end, and a rod portion between the hook end and the stop end,

a stop at the stop end of the rod, and

a removable locking fastener at the open end of the handle, the locking fastener further comprising a bore slidably receiving the rod portion of the hook rod and a stopping face, wherein the stopping face is sized to stop the stop of the hook rod.

10. The multi-purpose puller tool of claim 9 wherein the hook is a crook.

11. The multi-purpose puller tool of claim 9 wherein the hook is a right angle hook.

12. The multi-purpose puller tool of claim 9 wherein the hook is an acute angle hook.

13. The multi-purpose puller tool of claim 9 further comprising a plastic wedge lock having a bore sized to squeeze the rod portion of the hook rod, and having a conical end and a radial slit, and wherein the lock nut further comprises an interior chamber having a conical face sized to receive the conical end of the wedge lock.

14. A multi-purpose puller tool comprising:

a hollow handle having an open end, a head end, and a handle portion between the open end and the head end,

a transverse metal head at the head end of the handle,

a rod received by the open end of the hollow handle, the rod further comprising a hook end, a distal end, and a rod portion between the hook end and the distal end,

a removable locking fastener at the open end of the handle, the locking fastener further comprising a means to slidably receive the rod portion of the hook rod and to stop the hook rod.
