The present invention relates to a winch tool. More specifically, the present invention is concerned with a tool and a belt support adapted for use with a winch attached to a trailer for securing cargo.
The trucking industry carries cargo loads on semi-trailers pulled by road tractors. Various types of trailers exist for different purposes. Enclosed trailers, flat deck or float-type trailers are among the most popular types of trailers on the road these days. The use of a flat deck trailer requires straps or belts to secure the cargo load on the flat deck. The retaining straps are disposed on the trailer according to the size and shape of the cargo load.
Several winches are usually attached on the sides of the trailer for tying the cargo load on the flat deck trailer. Each winch includes a belt that can be wound on the rotatable barrel of the winch to secure the cargo load. Common winches are strong but slow to operate because the barrel of the winch is not adapted to continuously rotate about its rotation axis. A ratchet-type mechanism is located on one axial side of the barrel to maintain tension in the belt. A removable lever, installed in a radial opening located on the other axial side of the rotatable barrel, actuates the ratchet-type mechanism. The lever must be removed and re-installed in the radial openings several times to perform a complete rotation of the barrel. The pivotal movement of the lever is restricted given the proximity of the trailer's frame that precludes complete rotational movements of the lever about the rotational axis of the winch's barrel. Repetitive installation, pivotal movement and removal of the lever slowly and progressively winds and increases tension in the belt.
The belts remaining in winches installed on road trailers are subject to poor road and weather conditions and must preferably be removed from the winches when they are not used. Removing the belts also prevents the belts from being stolen. In any case, removing the belts from winches and manually re-winding them back in a compact arrangement so that they are easily storable is a time consuming process. The winch is not really helpful for winding the belts for storage because it is not possible to remove a wound belts from the winch's barrel. Even if a wound belt could be removed from the barrel, the slow winch action would likely discourage the use of the winch to wind the belts.
Therefore, a system for reducing the time needed to actuate a winch has been felt over existing systems. There is also a need for a mechanism for winding unused belts for storage. These and other needs will likely become apparent for a person skilled in the art of winches in view of the forgoing description and the appended figures.
More specifically, in accordance with the present invention, there is provided a winch tool adapted to continuously rotate the barrel of a winch installed on a road trailer.
In accordance with another aspect of the present invention, there is provided a winch tool adapted to efficiently wind a belt in a compact storable configuration that can be removed from the winch without unwinding the belt.
Another aspect of the present invention provides a winch tool that is removable from the winch when not in use.
One other aspect of the present invention provides a winch tool transforming a reciprocal rotation into a continuously rotational movement.
An aspect of the present invention provides a winch tool for actuating a winch, the winch comprising a winch frame; a barrel defining a rotation axis and being rotatably supported by the winch frame to allow rotation of the barrel about the rotation axis, the barrel having an external shape adapted to accommodate a belt wound thereon, the barrel having a first barrel end radially and axially accessible externally of the winch frame and a second barrel end, axially opposed to the first barrel end and axially accessible externally of the winch frame, the first barrel end having a substantially cylindrical exterior surface being disposed at a radius from the rotation axis; a barrel slot longitudinally disposed on the barrel and extending through the barrel; a radial opening disposed on the first barrel end and adapted to receive a lever to apply a rotational force on the barrel about the rotation axis, the radial opening being radial to the rotation axis of the barrel; and an axial opening disposed on the second barrel end, the axial opening being in communication with the barrel slot, the axial opening being disposed axially in respect to the rotation axis of the barrel; the tool comprising: a handle having a first end and a second end, the first end and the second end defining a longitudinal axis there between; a connector rotatably fastened to the first end of the handle; and a protrusion extending from the connector, the protrusion being configured to engage the radial opening of the barrel, a rotational movement of the connector to cause rotational movement of the barrel when the tool is connected to the barrel.
In another aspect, the present invention provides a tool for actuating a winch having a connector with a substantially semicircular shape adapted to enter in contact with the substantially cylindrical exterior surface of the first barrel end.
One other aspect of the present invention provides a winch tool adapted to engage the winch in a first direction and disengage the winch tool when the rotational movement of the connector about the rotational axis is in a second direction opposed to the first direction.
In yet another aspect, the present invention provides a connector laterally spaced from the longitudinal axis of the handle to prevent an interference between the connector and the handle when the connector rotates about the handle.

Additional and/or alternative features, aspects, and advantages of embodiments of the present invention will become apparent from the following description, the accompanying drawings, and the appended claims.
For a better understanding of the present invention, as well as other aspects and further features thereof, reference is made to the following description which is to be used in conjunction with the accompanying drawings, where:
A tool 10 for rotating a winch 60 used to secure cargo on a flat bed trailer in the trucking industry is shown in
The tool 10 includes a handle 14 having a grip 18 on one end and a cylinder 38, disposed perpendicularly to the handle 14, on the other end of the handle 14. The cylinder 38 defines a pivot axis 34. The cylinder 38 is adapted to receive an hollowed bushing 32 to reduce the friction inside the cylinder 38 and to prevent any friction noise. A spindle 46 is rotatably inserted inside the bushing 38 and is secured on the other side with a cap 42 to prevent the spindle 46 and the bushing from exiting the bore 32. Alternatively, the spindle 46 could be secured in place with a “C” clip, a snap ring or another means for locking a shaft in place while permitting rotational movements. This mechanical connection allows the spindle 46 to freely rotate in the bushing 32 about the pivot axis 34.
The spindle 46 rotatably interconnects the handle 14 with a connector 26. In the illustrative embodiment, the connector 26 is welded on the spindle 46 and is disposed on one lateral side of the handle 14 to allow uninterrupted rotational movement of the connector 26 about the pivot axis 34. The tool 10, when typically held by the grip 18, transforms a reciprocal movement of the handle 14 into a rotational movement of the connector 26. Once the connector 26 is secured to the barrel 80 of the winch 60 the continuous rotational movement of the connector 26 provides a continuous rotational movement to the winch 60 to wind a belt thereon. Conversely, repetitive pivotal movements are required when using a prior art lever.
It can be appreciated from
The handle 14 and the connector 26 are preferably made of aluminum for strenght and light weight. Aluminum allows the handle 14 to be bent for improving the ergonomics of the tool 10. The cylinder 38 could also be made of aluminum and be directly welded to the handle 14. The protrusion 30, also preferably made of aluminium, is welded or fastened to the connector 26. All parts are anodized to protect the metal surface of each part of the tool 10. Alternatively, the handle 14 and the connector 26 could be made of nylon charged plastic or any other materials offering sufficient strenght without departing from the scope of the present invention.
With reference to
The frame 72 of the winch 60 includes two parallel members, each having an opening adapted for rotatably receiving a barrel 80 rotatable about axis 76. A slot 84 (not visible in
The first barrel end 81 of the winch 60 is provided with an opening 86 radially extending there through to insert a prior art lever, rotate the barrel 80 and increase tension in the belt 88. The same opening 86 is used by the tool's protrusion 30 on the connector 26 to engage the barrel 80.
A ratchet-type mechanism is located on the second barrel end 82 disposed on the left side of the winch 60. The second barrel end 82 includes a ratchet gear 64 and a ratchet lock 68 to selectively prevents rotational movement of the barrel 80 in a first direction 48 while allowing free movement in the opposite direction 50. The ratchet lock 68 can be disengaged from the ratchet gear 64 to allow free rotation of the barrel 80 in both directions. The second barrel end 82 of the winch 60 further includes an axial opening 94 giving access to the hollowed internal portion 85 (illustrated on
The protrusion 30 temporarily positions the connector 26 on the exterior cylindrical surface 92 of the first barrel end 81 such that the connector 26 and the handle 14 can generate a rotational movement of the barrel 80 about the axis 76. Once the connector 26 is installed over the exterior cylindrical surface 92 and the protrusion 30 is secured in one of the openings 86, the barrel 80 can rotate with the rotation of the connector 26 in the first direction 48. A user applying a reciprocal movement to the handle 14 will continuously rotate the barrel 80 of the winch 60 to wind the belt 88 thereon. Conversely, movement of the connector 26 in the opposite direction 50 will disconnect the protrusion 30 and the connector 26 from the first barrel end 81.
The body 104 further includes a cap 120 welded on one side to secure the threaded portion 124 of the retractable portion 128. The body 104 has an hollowed center and is provided with a radius 106 on each side of the slot 108 to prevent any damages to the belt 88. The slot 108 is sized and designed to receive a belt 88 in a preferably slidable fashion such that the belt 88 is easily installed and maintained in the slot 108. All parts are made of steel but could be made of another material without departing from the scope of the present invention.
A left-handed thread 124 is used on the retractable portion 128 instead of a classic right-hand thread to avoid any undesired unscrewing of the retractable portion 128 during normal operation of the winch 60 with the belt support 100. The rotational movement of the winch 60 and the tension on the strap 88 winding on the body 104 would force a right-hand thread to unscrew. Using a left-hand threaded portion 124 on the retractable portion 128 ensures the belt support 100 remains firmly connected to the winch 60 when in operation.
The belt support 100 is used to efficiently wind a belt 88 removed from the winch 60 for storage. When the strap is completely removed from the winch 60, the tip of the belt 88 is inserted in the slot 108. Radiuses 106 (shown on
The belt 88 is rapidly wound on the belt support 100 by using the tool 10. The roll 148 of belt 88 is removed from the body 104 by axially pulling the wound roll 148 of belt 88 away from the winch 60 as illustrated by arrow 150. The diameter of the body 104 does not increase toward the side opposed to the cap 120 (shown on
The embodiment described herein are for illustrative purpose only and does not limit the scope of the present specification to a curved connector 26 connecting an end of the winch 60. All other structures suitable for connecting the handle 12 with the barrel 80 for efficiently rotating the barrel 80 are considered within the scope of the present application.
Although the present invention has been described hereinabove by way of specific embodiments thereof, it can be modified, without departing from the spirit and nature of the subject invention as defined in the appended claims.
The present invention claims priority to U.S. provisional patent application No. 60/806,980 entitled: WINCH TOOL, filed Jul. 11, 2006, the entirety of which is incorporated herein by reference.
