Protective sheath with integral biased flap closure
View Patent ↗The invention provides a protective sheath for receiving elongated items. The protective sheath includes first and second elongated substrates connected to one another about at least one living hinge. The first and second elongated substrates are moveable relative to one another between an open configuration wherein the first and second substrates are positioned substantially side by side adjacent to one another and a closed configuration wherein the first and second substrates at least partially overlying one another. The protective sheath also includes a first flap attached to the first substrate along an edge. The first flap is resiliently biased into a position overlying the first substrate and operable to engage the second substrate when the first and second substrates are in the closed configuration.
1. A protective sheath for receiving elongated items comprising:
first and second elongated substrates connected to one another by a living hinge for relative movement between an open configuration wherein said first and second substrates are positioned substantially side by side adjacent to one another and a closed configuration wherein said first and second substrates overlie one another in a generally flat configuration;
a first flap attached to said first substrate along an edge opposite said living hinge, said first flap being resiliently biased in overlying relation to said first substrate and engaging said second substrate when said first and second substrates are in said closed configuration wherein at least a portion of said second substrate is sandwiched between said first flap and said first substrate, said first flap resisting movement of said second substrate from said closed configuration and maintaining said second substrate in said closed configuration without aid of a fastener by engaging and holding said second substrate between said first substrate and said flap under said bias, said flap being resiliently deformable against said bias under an externally applied force to selectively release said second substrate from said closed configuration; and
a second living hinge connecting said first flap and said first substrate to one another, wherein said first and second substrates and said first flap and said living hinges are further defined as being unitary and integrally formed from flexible, resilient polymer sheet materials selected from the group consisting of polypropylene, polyester, and nylon.
2. The protective sheath of claim 1 wherein said first and second elongated substrates are further defined as being immediately adjacent to one another.
3. The protective sheath of claim 1 wherein said flap is further defined as indirectly engaging said second substrate when said first and second substrates are in said closed configuration.
4. The protective sheath of claim 1 wherein said first and second substrates are further defined as having substantially the same width.
5. The protective sheath of claim 1 wherein said flap is further defined as extending substantially along an entire length of said first substrate.
6. The protective sheath of claim 1 wherein said first and second substrates and said first flap are further defined as being formed from interlaced polymer monofilaments.
7. The protective sheath of claim 6 wherein said first and second substrates and said first flap are further defined as being woven from one of polyester and nylon filaments.
8. A protective sheath for receiving elongated items comprising:
first and second elongated substrates connected to one another about at least one living hinge for relative movement between an open configuration wherein said first and second substrates are positioned substantially side by side adjacent to one another and a closed configuration wherein said first and second substrates at least partially overlying one another;
a first flap attached to said first substrate along an edge and resiliently biased into a position overlying said first substrate and operable to engage said second substrate when said first and second substrates are in said closed configuration for limiting movement of said second substrate from said closed configuration and being resiliently deformable to release said second substrate from said closed configuration;
another living hinge connecting said first flap and said first substrate to one another, wherein said first and second substrates and said first flap and said living hinges are further defined as being unitary and integrally formed from flexible, resilient polymer sheet materials selected from the group consisting of polypropylene, polyester, and nylon;
at least one intermediate substrate disposed between said first and second substrates; and
wherein said at least one intermediate substrate further comprises:
a first intermediate substrate disposed between said first and second substrates; and
a second intermediate substrate disposed between said first substrate and said first intermediate substrates.
9. The protective sheath of claim 8 wherein said at least one intermediate substrate is further defined as being narrower than at least one of said first and second substrates.
10. The protective sheath of claim 8 wherein said at least one living hinge further comprises:
a first living hinge disposed between said first intermediate substrate and said first substrate;
a second living hinge disposed between said first intermediate substrate and said second intermediate substrate; and
a third living hinge disposed between said second intermediate substrate and said second substrate.
11. A protective sheath for receiving elongated items comprising:
first and second elongated substrates connected to one another about at least one living hinge for relative movement between an open configuration wherein said first and second substrates are positioned substantially side by side adjacent to one another and a closed configuration wherein said first and second substrates at least partially overlying one another;
a first flap attached to said first substrate along an edge and resiliently biased into a position overlying said first substrate and operable to engage said second substrate when said first and second substrates are in said closed configuration for limiting movement of said second substrate from said closed configuration and being resiliently deformable to release said second substrate from said closed configuration;
a second living hinge connecting said first flap and said first substrate to one another, wherein said first and second substrates and said first flap and said living hinges are further defined as being unitary and integrally formed from flexible, resilient polymer sheet materials selected from the group consisting of polypropylene, polyester, and nylon; and
a second flap resiliently biased into a position overlying said second substrate wherein at least a portion of said second flap is positionable between said first flap and said first substrate when said first and second substrates are in said closed configuration.
