Hook termination systems and methods for ropes
A hook assembly comprises a hook member and a pin assembly. The hook member defines a base portion, a hook, and first and second pin arms. The hook extends from the base portion and defines a first, second, third, and fourth hook portions and a hook opening. First and second lock projections extend from the second hook portion and fourth hook portions to define a lock gap. The hook opening has a first hook opening dimension extending between the second hook portion and the fourth hook portion and a second opening dimension extending between the third hook portion and the lock gap. The first and second pin arms extend from the base portion. The pin assembly engages the first and second pin arms. The first rope segment engages the pin assembly and the second rope segment engages the third hook portion to place the hook assembly under tension.
1. A hook assembly for connecting a first rope segment to a second rope segment comprising:
a hook member defining
a base portion,
a hook extending from the base portion, the hook defining
a first hook portion,
a second hook portion from which a first lock projection extends,
a third hook portion,
a fourth hook portion from which a second lock projection extends, where a lock gap is defined by the first and second lock projections, and
a hook opening having
a first hook opening dimension extending between the second hook portion and the fourth hook portion and
a second opening dimension extending between the third hook portion and the lock gap, and
first and second pin arms extending from the base portion; and
a pin assembly configured to engage the first and second pin arms; wherein
the first rope segment engages the pin assembly and the second rope segment engages the third hook portion to place the hook assembly under tension.
2. A hook assembly as recited in claim 1 , in which a length of the lock gap is shorter than either of the first hook opening dimension and the second hook opening dimension.
3. A hook assembly as recited in claim 2 , in which the second rope segment defines a first dimension and a second dimension, where the first dimension is smaller than the length of the lock gap and the second dimension is larger than the length of the lock gap.
4. A hook assembly as recited in claim 1 , in which the second rope segment defines a first dimension and a second dimension, where the first dimension is smaller than a length of the lock gap and the second dimension is larger than the length of the lock gap.
5. A rope assembly comprising:
a first rope segment;
a second rope segment,
a hook member defining
a base portion,
a hook extending from the base portion, the hook defining
a first hook portion,
a second hook portion from which a first lock projection extends,
a third hook portion,
a fourth hook portion from which a second lock projection extends, where a lock gap is defined by the first and second lock projections, and
a hook opening having
a first hook opening dimension extending between the second hook portion and the fourth hook portion and
a second opening dimension extending between the third hook portion and the lock gap, and
first and second pin arms extending from the base portion; and
a pin assembly configured to engage first and second pin arms; wherein
the first rope segment engages the pin assembly and the second rope segment engages the third hook portion to place the hook assembly under tension.
6. A rope assembly as recited in claim 5 , in which a length of the lock gap is shorter than either of the first hook opening dimension and the second hook opening dimension.
7. A rope assembly as recited in claim 6 , in which the second rope segment defines a first dimension and a second dimension, where the first dimension is smaller than the length of the lock gap and the second dimension is larger than the length of the lock gap.
8. A rope assembly as recited in claim 7 , in which the second rope segment defines the first dimension when the rope assembly is under tension.
9. A rope assembly as recited in claim 5 , in which the second rope segment defines a first dimension and a second dimension, where the first dimension is smaller than a length of the lock gap and the second dimension is larger than the length of the lock gap.
10. A rope assembly as recited in claim 9 , in which the second rope segment defines the first dimension when the rope assembly is under tension.
11. A rope assembly as recited in claim 5 , in which the rope assembly comprises first and second end rope segments and at least one intermediate rope segment, in which the first rope segment is formed by the second end rope segment and the second rope segment is formed by one of the at least one intermediate rope segment.
12. A rope assembly as recited in claim 11 , in which:
the rope assembly comprises a plurality of intermediate rope segments; and
an effective length of the rope assembly is determined by engaging the hook member with a selected intermediate rope segment of the plurality of intermediate rope segments.
13. A method of connecting first and second structural members, comprising the steps of:
operatively connecting a first end rope segment to the first structural member;
operatively connecting the first end rope segment to a second end rope segment with a plurality of intermediate rope segments;
providing a hook member defining
a base portion,
a hook extending from the base portion, the hook defining
a first hook portion,
a second hook portion from which a first lock projection extends,
a third hook portion,
a fourth hook portion from which a second lock projection extends, where a lock gap is defined by the first and second lock projections, and
a hook opening having
a first hook opening dimension extending between the second hook portion and the fourth hook portion and
a second opening dimension extending between the third hook portion and the lock gap, and
first and second pin arms extending from the base portion; and
forming a rope assembly by
arranging a pin assembly to engage first and second pin arms and the second end rope segment, and
engaging the third hook portion with a selected one of the intermediate rope segments;
connecting the first end rope segment to the first structural member; and
connecting one of the plurality of intermediate rope segments to the second structural member.
14. A method as recited in claim 13 , in which a length of the lock gap is shorter than either of the first hook opening dimension and the second hook opening dimension.
15. A method as recited in claim 14 , in which the second end rope segment defines a first dimension and a second dimension, where the first dimension is smaller than a length of the lock gap and the second dimension is larger than the length of the lock gap.
16. A method as recited in claim 15 , in which the second rope segment defines the first dimension when the rope assembly is under tension.
17. A method as recited in claim 13 , in which the second end rope segment defines a first dimension and a second dimension, where the first dimension is smaller than a length of the lock gap and the second dimension is larger than the length of the lock gap.
18. A method as recited in claim 17 , in which the second rope segment defines the first dimension when the rope assembly is under tension.
19. A method as recited in claim 13 , in which an effective length of the rope assembly is determined by:
identifying a selected intermediate rope segment from the plurality of intermediate rope segments; and
engaging the hook member with the selected intermediate rope segment.
