Abstract
A reinforced bungee cord tie down for securing cargo without becoming over-stretched. The reinforced bungee cord tie down includes an elongate elastic member with each of the ends of the elastic member having a hook coupled thereto. The ends of an elongate inelastic flexible member are coupled to the ends of the elastic member such that the flexible member extends between the ends of the elastic member. The length of the flexible member is greater than the length of the elastic member when in a relaxed state and less than the length of the elastic member when in a fully stretched state.
Claims6
A tie down, comprising:
- an elongate elastic member having a pair of opposite ends;
- said elastic member having a relaxed stated from which said elastic member may be stretched to a stretched state, said elastic member having a first length when in said relaxed state and a second length greater than said first length when in said stretched state;
- each of said ends of said elastic member having a hook coupled thereto;
- an elongate inelastic flexible member having a pair of opposite ends, and a length defined between said ends of said flexible member;
- one of said ends of said flexible member being coupled to one of said ends of said elastic member and the other of said ends of said flexible member being coupled to the other of said ends of said elastic member;
- said length of said flexible member being greater than said first length of said elastic member and less than said second length of said elastic member;
- wherein each of said hooks has a resilient coiled portion, wherein said coiled portion of each hook is coiled around the associated adjacent end of said elastic member such that each coiled member constricts a corresponding portion of said elastic member adjacent the associated adjacent end of said elastic member such that said coiled portion of each hook holds the respective hook to associated adjacent end of said elastic member;
- and
- wherein each end of said flexible member is extended between the constricted corresponding portion of said elastic member adjacent the associated end of the elastic member and said coiled portion of the corresponding hook such that each end of said flexible member is held between the associated constricted corresponding portion of the elastic member and coiled portion of the corresponding hook.

- said elastic member having a relaxed stated from which said elastic member may be stretched to a stretched state, said elastic member having a first length when in said relaxed state and a second length greater than said first length when in said stretched state;
- each of said ends of said elastic member having a hook coupled thereto;
- an elongate inelastic flexible member having a pair of opposite ends, and a length defined between said ends of said flexible member;
- one of said ends of said flexible member being coupled to one of said ends of said elastic member and the other of said ends of said flexible member being coupled to the other of said ends of said elastic member;
- said length of said flexible member being greater than said first length of said elastic member and less than said second length of said elastic member;
- and
- wherein said elasticity of said elastic member is at least about five times that of said flexible member.

A tie down, comprising:
- an elongate elastic member having a pair of opposite ends and a longitudinal axis extending between said ends of said elastic member;
- said elastic member having a generally circular transverse cross section taken substantially perpendicular to said longitudinal axis of said elastic member;
- said elastic member comprising an elongate elastic core and an elongate elastic sheath disposed about said elastic core to substantially cover said elastic core between said ends of said elastic member;
- said elastic member having a length defined between said ends of said elastic member;
- said elastic member having a relaxed stated from which said elastic member may be stretched to a stretched state, said elastic member having a first length when in said relaxed state and a second length greater than said first length when in said stretched state;
- each of said ends of said elastic member having a hook coupled thereto and outwardly extending therefrom;
- each of said hooks having an arcuate end portion, a resilient coiled portion and an elongate middle portion connecting said end portion to said coiled portion of the respective hook;
- said coiled portion of each hook being coiled around the associated adjacent end of said elastic member such that each coiled member constricts a corresponding portion of said elastic member adjacent the associated adjacent end of said elastic member such that said coiled portion of each hook holds the respective hook to associated adjacent end of said elastic member;
- said middle portions of said hooks being outwardly extended from the associated adjacent end of said elastic member generally parallel to said longitudinal axis of said elastic member;
- said end portions of said hooks each having a concavity facing towards the associated adjacent end of said elastic member;
- an elongate inelastic flexible member having a pair of opposite ends, and a length defined between said ends of said flexible member;
- one of said ends of said flexible member being coupled to one of said ends of said elastic member and the other of said ends of said flexible member being coupled to the other of said ends of said elastic member such that said flexible member extends between said ends of said elastic member;
- wherein each end of said flexible member is extended between the constricted corresponding portion of said elastic member adjacent the associated end of the elastic member and said coiled portion of the corresponding hook such that each end of said flexible member is held between the associated constricted corresponding portion of the elastic member and coiled portion of the corresponding hook;
- each of said ends of said flexible member terminating at a stop for preventing pulling out of each end of said flexible member from between the associated constricted corresponding portion and coiled portion;
- wherein each of said stops comprises a knot formed at the respective end of said flexible member;
- and
- said length of said flexible member being greater than said first length of said elastic member when in said relaxed state and less than said second length of said elastic member when said stretched state, said flexible member limiting stretching of said elastic member to an intermediate stretched state between said relaxed state and said stretched state wherein said elastic member has a third length greater than said first length and less than said second length and about equal to said length of said flexible member.
