ABSTRACT:

Not applicable.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not applicable.
BACKGROUND OF THE INVENTION
Straps are commonly used to secure cargo on a vehicle, as a truck, ship or airplane. Often two straps or the two ends of one strap are connected with a buckle ratchet winch. The winch has a lever actuator for winding one end of the strap on a reel to tighten the strap (or straps) about the cargo. The configuration of the cargo and of the cargo space of the vehicle sometimes require that the winch be in a location where it is inconvenient to actuate the lever by hand. Prete et al. U.S. Pat. No. 4,510,651 and Sergent U.S. Pat. No. 5,549,429 disclose lever extension tools for such a strap winch. The tools of both patents have straight bar shanks and handles which are difficult, if not impossible, to use in some situations.
BRIEF SUMMARY OF THE INVENTION
The invention provides a tool for a cargo strap buckle ratchet winch which has a configuration that facilitates manipulation of the winch lever in situations where the winch is inconveniently located.
More particularly, one feature of the invention is that the tool has an elongate shank, a transverse handle at one end of the shank, and means at the other end of the shank for engagement with the strap winch lever. More particularly, the handle has a C-configuration with a first section extending at a right angle to the shank, a second section extending at a right angle to the first section and parallel to the shank, and a grip section extending at a right angle to the second section, transverse to the shank and parallel with the first section.
Another feature of the tool is that the means for engagement with the strap winch lever is a fulcrum plate secured to the shank. The fulcrum plate has a transverse extent parallel with the transverse handle. More particularly, the fulcrum plate has a planar proximal section attached to the shank and a planar distal section remote from the shank and extending at an obtuse angle with respect to the proximal section. A foot portion of the fulcrum plate extends at a right angle to the distal plate section.
Further features and advantages of the invention will be apparent from the following specification and the drawings.
