Abstract

A binding apparatus including a plurality of generally coaxially arranged binding coils. Each binding coil includes a pair of generally parallel wires terminating in a tip. Each binding coil is coupled to an adjacent binding coil by a connection portion extending generally parallel to an axis of the binding apparatus. At least one binding coil is directly circumferentially attached to itself, or to a connection portion.

Claims

1. A binding apparatus system comprising:

a binding apparatus including a plurality of coaxially arranged binding coils, each binding coil including a pair of parallel wires terminating in a tip, each binding coil being coupled to an adjacent binding coil by a connection portion extending parallel to an axis of the binding apparatus and at least partially axially offset from each tip; and

a locking device extending at least partially circumferentially and coupling portions of the binding apparatus, the locking device including a spine oriented parallel with the axis of the binding apparatus, the locking device further including at least two hook portions coupled to the spine on opposite sides of the spine, each hook portion lockingly engaging a portion of the binding apparatus.

2. The binding apparatus system of claim 1 wherein the binding apparatus includes an axially extending gap, and wherein the locking device circumferentially extends across the gap.

3. The binding apparatus system of claim 1 wherein each tip has an axial length less than an axial length of an adjacent connecting portion, and wherein each tip is axially offset from each connecting portion.

4. The binding apparatus system of claim 1 wherein each hook portion wraps at least partially around a portion of said binding apparatus.

5. The binding apparatus of claim 1 wherein each hook is axially aligned with another hook of said locking device.

6. The binding apparatus of claim 1 wherein each hook is axially offset from and does not axially overlap with any other hook of said locking device.

7. The binding apparatus of claim 1 wherein the locking device has an axial length less than a combined axial length of a connection portion and a tip portion.

8. The binding apparatus of claim 1 wherein the locking device has no more than three hook portions.

9. The binding apparatus system of claim 1 wherein the binding apparatus is made of a single continuous wire, and wherein the locking device is made of a different piece of material than the binding apparatus.

10. The binding apparatus system of claim 1 wherein the locking device is coupled, at one circumferential end, to a binding coil at or adjacent to the tip of the spine, wherein the locking device is coupled, at the other circumferential end, to one of said connection portions.

11. The binding apparatus system of claim 1 wherein said locking device circumferentially couples two adjacent connection portions together and to an opposed tip portion.

12. The binding apparatus system of claim 1 wherein the locking device has a pair of opposed circumferential ends, and each end is directly mechanically coupled to the binding apparatus.

13. The binding apparatus system of claim 1 wherein said locking device extends circumferentially less than 360 degrees.

14. The binding apparatus system of claim 1 wherein locking device is the only component circumferentially coupling portions of the binding apparatus at an axial position of said locking device.

15. The binding apparatus system of claim 1 wherein an entirety of said binding apparatus is made of a single wire component formed in a cylindrical shape.

16. The system of claim 1 wherein each hook portion extends outwardly from said spine in a direction perpendicular to the spine.

17. The system of claim 1 wherein each hook portion extends outwardly from said spine in a direction perpendicular to the spine.

18. The system of claim 1 wherein the spine is oriented parallel with the axis of the binding apparatus.

19. The system of claim 1 wherein a free, distal end of each hook portion is oriented perpendicular to the spine.

20. A binding apparatus system comprising:

a binding apparatus including a plurality of coaxially arranged binding coils, each binding coil including a pair of parallel wires terminating in a tip, each binding coil being coupled to an adjacent binding coil by a connection portion extending parallel to an axis of the binding apparatus and at least partially axially offset from each tip; and

a locking device extending at least partially circumferentially and coupling portions of the binding apparatus, the locking device including a spine oriented parallel with the axis of the binding apparatus, the locking device further including at least two hook portions coupled to the spine on opposite sides of the spine, each hook portion lockingly engaging a portion of the binding apparatus, wherein each hook portion is permanently and non-removably coupled to the binding apparatus.

21. A binding apparatus system comprising:

a locking device configured to couple portions of a wire binding apparatus at least partially in a circumferential direction, the locking device including a spine configured to be oriented parallel with an axis of the binding apparatus, the locking device further including at least two hook portions coupled to the spine on opposite sides of the spine and extending outwardly from said spine in a direction perpendicular to the spine, each hook portion being configured to lockingly engaging a portion of the binding apparatus, wherein said hook portions are least partially axially offset.

22. The binding apparatus system of claim 21 further comprising said wire binding apparatus including a plurality of coaxially arranged binding coils, each binding coil including a pair of parallel wires terminating in a tip, each binding coil being coupled to an adjacent binding coil by a connection portion extending parallel to an axis of the binding apparatus.

23. The binding apparatus system of claim 22 wherein said connection portion is at least partially axially offset from each tip.

24. The system of claim 21 wherein each hook portion has a curved inner surface configured to receive a portion of the wire binding apparatus therein, and wherein the curved inner surface curves about a center axis that is parallel to the spine.

25. The system of claim 22 wherein the spine is oriented parallel with the axis of the binding apparatus.

26. A method for forming a binding apparatus system comprising:

providing a binding apparatus including a plurality of coaxially arranged binding coils, each binding coil including a pair of parallel wires terminating in a tip, each binding coil being coupled to an adjacent binding coil by a connection portion extending parallel to an axis of the binding apparatus and at least partially axially offset from each tip;

providing a locking device including a spine and at least two hook portions coupled to the spine on opposite sides of the spine; and

coupling said locking device to said binding apparatus such that the locking device couples portions of the binding apparatus at least partially in a circumferential direction, said spine is arranged parallel to said axis, and such that each hook portion lockingly engages a portion of the binding apparatus.
