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

1-20. -20. (canceled)

21. A binding apparatus system comprising:

a binding apparatus including a plurality of generally coaxially arranged binding coils, each binding coil including a pair of generally 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

a locking device including a spine and a plurality of finger elements extending outwardly away from said spine, each finger element being configured to fit between the pair of wires of a binding coil to couple the locking device to the binding apparatus.

22. The binding apparatus system of claim 21 wherein each finger element has a pair of opposed angled leading edge surfaces and a pair of opposed trailing edge surfaces, wherein the leading edge surfaces and trailing edge surfaces are configured such that the force required to insert each finger element between the pair of binding wires is less than the force required to remove the finger element from the pair of binding wires.

23. The binding apparatus system of claim 21 wherein each finger element has a maximum width greater than a width between the pair of wires of the associated binding coil.

24. The binding apparatus system of claim 21 wherein each finger element is configured to spread apart the pair of wires of the associated binding coil when the finger element is urged generally radially inwardly into the binding apparatus, and to allow the pair of wires to at least partially converge to trap the finger element therein once the finger element has been sufficiently inserted.

25. The binding apparatus system of claim 21 wherein the spine is generally flat and planar, and wherein each finger element is generally co-planar with the spine.

26. A locking apparatus for a twin-wire binding apparatus comprising:

a twin-wire apparatus comprising;

a continuous length of wire bent in a generally circular manner about a lengthwise axis to form opposing alternating generally u-shaped tip sections and joining sections in which the joining sections are of greater width than the tip sections; and

a snap-in comb lock component comprised of;

a spine element; and

a plurality of finger elements each including a catch apparatus protruding from the spine element.

27. The locking apparatus of claim 26, wherein each catch apparatus protrudes at substantially 90 degrees from the spine element.

28. The locking apparatus of claim 26 wherein the plurality of finger elements are generally arrow shaped and adapted to fit within the width of the tip sections such that once inserted through a tip section the wide trailing edge of the arrow shape acts as a catch apparatus to keep the finger element from dislodging.

29. A snap-in comb lock component for use with a twin-wire binding apparatus comprising:

a spine element; and

a plurality of finger elements each including a catch apparatus protruding from the spine element.
