Description
TITLE OF THE INVENTION:
Method and apparatus for locking a load binder FIELD OF THE INVENTION
The present invention relates to a method and associated apparatus which is used to lock a load binder against untended release.
BACKGROUND OF THE INVENTION
A truck driver uses load binders to secure his load. If those load binder should release, there is a danger that the load will shift and either fall from the truck or penetrate the cab. U.S. Patents 4,422,218 (Brasseaux 1983) and 5,429,462 (Anderson 1995) are examples of load binders. U.S. Patents 2,564,821 (Smith 1947), 3,954,252 (Lyons 1976) and 6,477,747 (Flagg 2002) are examples of load binders that have some means for locking. As most load binders in use today do not have built in locking mechanisms, there is a need for an apparatus for locking a load binder.
SUMMARY OF THE INVENTION
According to one aspect there is provided an apparatus for locking a load binder, which includes a metal cable having a first end and a second end. A male body is positioned at the first end of the cable. A female body positioned at the second end of the cable. Means are provided for preventing the male body from being withdrawn from the female body.
According to another aspect there is provided a method of locking a load binder. A
first step involves providing an apparatus as described above. A second step involves extending the metal cable through a chain and around a body and lever of a load binder, with the lever in a locked position. A third step involves inserting the male body into the female body and securing the male body against being withdrawn from the female body.
The positioning of the cable prevents the lever for the load binder from being moved from the locked position to a release position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, an apparatus for locking a load binder generally identified by reference numeral 10, will now be described with reference to FIG. 1 through 3.
Structure and Relationship of Parts:
Referring to FIG. 1, apparatus 10 includes a metal cable 12 having a first end 14 and a second end 16. A male body 20 is positioned at first end 14 of metal cable 12. Male body 20 has a diameter which is larger than the diameter of metal cable 12. A
female body 24 is positioned at second end 16 of metal cable 12. Referring to FIG. 2 and 3, female body includes a key hole opening 26 with a first portion 28 adapted to accommodate the diameter of metal cable 12 but not the diameter of male body 20, whereas second portion 30 is adapted to accommodate the diameter of male body 20. First portion 28 and second portion 30 of key hole opening 26 are in communication with one another, such that male body 20 is allowed to pass through second portion 30, and metal cable 12 is received by first portion 28.
Operation:
The use and operation of apparatus 10 will now be described with reference to FIG. 1 through 5. FIG. 4 displays a simplified example of a load binder 32 in the open position. A
lever 34 is connected to a body including a first arm 36 and a second arm 38.
Each are secured to load binder 32 at a first hinge-point 40 and a second hinge-point 42, respectively.
The end of first arm 36 which is not connected to first hinge-point 40 is connected to a set of chain links 44, which itself connects to a hook 46. Load binder 32 is being used to secure a chain 48. The end of second arm 38 which is not connected to second hinge-point 42 is also connected to another set of chain links 50, which then connects to a second hook 52. In this case, hooks 46 and 52 are connected to a loose chain 48 to be tightened. FIG.
5 displays load binder 32 in the closed position and secured with apparatus 10. Lever 34 has been rotated, pulling hooks 46 and 52 closer together, which in turn tightens chain 48.
Metal cable 12 of apparatus 10 is then extended through chain 48, and around first arm 36 and lever 34. In order to secure load binder 36, male body 20 is inserted into second portion 30 of key hole opening 26, and metal cable 12 is shifted into first portion 28 of key hole opening 26, as shown in FIG. 2 and 3. Cable 12 is maintained in first portion of keyhole opening 26 because of the inherent resilience of cable 12. Because first portion 28 of key hole opening 26 will not accommodate the diameter of male body 20, male body 20 is unable to be withdrawn through first portion 28, and metal cable 12 is maintained in that position. Although apparatus 10 includes female body 24 as depicted, it could alternatively include any device that would allow male body 20 to be inserted into female body 24 while preventing male body 20 from being withdrawn from female body 24. Cable 12 is maintained in first portion 28 of key hole opening 26 by the resilience of cable 12, and the positioning of metal cable 12 prevents lever 34 of load binder 32 from being moved from the locked position to a release position.
In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.

A truck driver uses load binders to secure his load. If those load binder should release, there is a danger that the load will shift and either fall from the truck or penetrate the cab. U.S. Patents 4,422,218 (Brasseaux 1983) and 5,429,462 (Anderson 1995) are examples of load binders. U.S. Patents 2,564,821 (Smith 1947), 3,954,252 (Lyons 1976) and 6,477,747 (Flagg 2002) are examples of load binders that have some means for locking. As most load binders in use today do not have built in locking mechanisms, there is a need for an apparatus for locking a load binder.
SUMMARY OF THE INVENTION
According to one aspect there is provided an apparatus for locking a load binder, which includes a metal cable having a first end and a second end. A male body is positioned at the first end of the cable. A female body positioned at the second end of the cable. Means are provided for preventing the male body from being withdrawn from the female body.
According to another aspect there is provided a method of locking a load binder. A
first step involves providing an apparatus as described above. A second step involves extending the metal cable through a chain and around a body and lever of a load binder, with the lever in a locked position. A third step involves inserting the male body into the female body and securing the male body against being withdrawn from the female body.
The positioning of the cable prevents the lever for the load binder from being moved from the locked position to a release position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, an apparatus for locking a load binder generally identified by reference numeral 10, will now be described with reference to FIG. 1 through 3.
Structure and Relationship of Parts:
Referring to FIG. 1, apparatus 10 includes a metal cable 12 having a first end 14 and a second end 16. A male body 20 is positioned at first end 14 of metal cable 12. Male body 20 has a diameter which is larger than the diameter of metal cable 12. A
female body 24 is positioned at second end 16 of metal cable 12. Referring to FIG. 2 and 3, female body includes a key hole opening 26 with a first portion 28 adapted to accommodate the diameter of metal cable 12 but not the diameter of male body 20, whereas second portion 30 is adapted to accommodate the diameter of male body 20. First portion 28 and second portion 30 of key hole opening 26 are in communication with one another, such that male body 20 is allowed to pass through second portion 30, and metal cable 12 is received by first portion 28.
Operation:
The use and operation of apparatus 10 will now be described with reference to FIG. 1 through 5. FIG. 4 displays a simplified example of a load binder 32 in the open position. A
lever 34 is connected to a body including a first arm 36 and a second arm 38.
Each are secured to load binder 32 at a first hinge-point 40 and a second hinge-point 42, respectively.
The end of first arm 36 which is not connected to first hinge-point 40 is connected to a set of chain links 44, which itself connects to a hook 46. Load binder 32 is being used to secure a chain 48. The end of second arm 38 which is not connected to second hinge-point 42 is also connected to another set of chain links 50, which then connects to a second hook 52. In this case, hooks 46 and 52 are connected to a loose chain 48 to be tightened. FIG.
5 displays load binder 32 in the closed position and secured with apparatus 10. Lever 34 has been rotated, pulling hooks 46 and 52 closer together, which in turn tightens chain 48.
Metal cable 12 of apparatus 10 is then extended through chain 48, and around first arm 36 and lever 34. In order to secure load binder 36, male body 20 is inserted into second portion 30 of key hole opening 26, and metal cable 12 is shifted into first portion 28 of key hole opening 26, as shown in FIG. 2 and 3. Cable 12 is maintained in first portion of keyhole opening 26 because of the inherent resilience of cable 12. Because first portion 28 of key hole opening 26 will not accommodate the diameter of male body 20, male body 20 is unable to be withdrawn through first portion 28, and metal cable 12 is maintained in that position. Although apparatus 10 includes female body 24 as depicted, it could alternatively include any device that would allow male body 20 to be inserted into female body 24 while preventing male body 20 from being withdrawn from female body 24. Cable 12 is maintained in first portion 28 of key hole opening 26 by the resilience of cable 12, and the positioning of metal cable 12 prevents lever 34 of load binder 32 from being moved from the locked position to a release position.
In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
