Abstract

A locking system for a spool comprising a barrel, a flange, and a sliding lock. The sliding lock has at least one rail that slidably engages with at least one barrel detent and at least one flange detent to prevent rotation of the flange on the barrel. The sliding lock comprises at least one arm with at least one catch. The at least one catch can be removably locked into at least one recess on the flange.

First claim

What is claimed is:

1 . A spool locking system comprising:
a barrel comprising a first longitudinal end and a second longitudinal end, wherein at least the first longitudinal end comprises at least one barrel detent; a first flange removably affixable to the first longitudinal end of the barrel, wherein the first flange comprises at least one receiving location for a sliding lock, the receiving location comprising:
at least one flange detent, wherein the at least one flange detent is aligned with the at least one barrel detent; and
at least one sidewall having at least one recessed portion; and
the sliding lock comprising:
a body portion comprising a proximate end, a distal end, two sides, an outer surface and an inner surface;
at least one rail disposed on the inner surface of the body portion, wherein the at least one rail is configured to engage with the at least one flange detent and the at least one barrel detent, and wherein at least one sidewall of the at least one barrel detent is angled to direct the at least one rail into the correct alignment with the at least one barrel detent;
at least one flexible arm affixed to the body portion; and
at least one catch disposed on the at least one arm, wherein the catch is configured to engage with the at least one recessed portion of the flange receiving location and, once engaged with the at least one recessed portion of the flange receiving location, restricts disengagement with the at least one recessed portion.

2 . The spool locking system of claim 1 , wherein the spool is an industrial spool.

3 . The spool locking system of claim 1 additionally comprising a second flange removably affixable to the second longitudinal end of the barrel.

4 . The spool locking system of claim 1 comprising two flange detents aligned with two barrel detents.

5 . The spool locking system of claim 4 comprising at least two rails disposed on the inner surface of the body portion.

6 . The spool locking system of claim 1 , wherein the proximate end of the sliding lock body portion is radially inward on the flange of the distal end of the sliding lock body portion.

7 . The spool locking system of claim 1 , wherein the at least one rail initiates near the proximate end of the body portion, extends along the length of the body portion, and terminates near the distal end of the body portion.

8 . The spool locking system of claim 1 , wherein the at least one arm is biased toward an initial position and compressible by applying pressure to the arm.

9 . The spool locking system of claim 1 , comprising a first arm having a first catch, a second arm having a second catch, a first sidewall of the receiving location comprising a first recessed portion, and a second sidewall of the receiving location comprising a second recessed portion.

10 . The spool locking system of claim 8 , wherein a width from an apex of first catch to an apex of the second catch is greater than the distance between the first sidewall and the second sidewall, in a location radially outward of the recessed portion.

11 . The spool locking system of claim 1 comprising a first locked position wherein the at least one rail is positioned in the at least one flange detent and at least one barrel detent and the at least one catch is positioned within the at least one recessed portion; and
a second unlocked position wherein the at least one rail is not positioned within the at least one barrel detent and the catch is not positioned within the recessed portion.

12 . The spool locking system of claim 11 , wherein in the second unlocked position, the at least one rail is positioned within the at least one flange detent.

13 . The spool locking system of claim 1 , wherein a retaining portion extends from the distal end of the sliding lock, opposite the proximate end, wherein the retaining portion is configured to snap-fit onto a portion of a rib of the flange.

14 . The spool locking system of claim 1 , wherein a lip extends from the proximate end of the sliding lock, opposite the distal end, wherein the lip is configured to engage with the flange within the receiving location.

15 . The spool locking system of claim 14 wherein the lip is configured to engage with an edge of an offset portion of the flange.

16 . The spool locking system of claim 15 wherein the lip is configured to slide under the edge of the offset portion of the flange.

17 . The spool locking system of claim 14 , wherein upon disengagement, the at least one rail is positioned within the at least one flange detent.

18 . A method for locking a spool comprising:
providing a barrel comprising a first longitudinal end and a second longitudinal end, wherein at least the first longitudinal end comprises at least one barrel detent; providing a first flange comprising at least one receiving location for a sliding lock, the receiving location comprising at least one flange detent and at least one sidewall having at least one recessed portion; removably affixing the first flange to the first longitudinal end of the barrel; aligning the at least one barrel detent with the at least one flange detent; providing the sliding lock comprising:
a body portion comprising a proximate end, a distal end, two sides, an outer surface and an inner surface;
at least one rail disposed on the inner surface of the body portion;
at least one flexible arm integral with the body portion; and
at least one catch disposed on the at least one arm;
engaging the at least one rail with the at least one flange detent and the at least one barrel detent; and engaging the at least one catch with the at least one recessed portion.

19 . A method for unlocking a spool comprising:
providing a barrel comprising a first longitudinal end and a second longitudinal end, wherein at least the first longitudinal end comprises at least one barrel detent; providing a first flange comprising at least one receiving location for a sliding lock, the receiving location comprising at least one flange detent and at least one sidewall having at least one recessed portion; removably affixing the first flange to the first longitudinal end of the barrel; aligning the at least one barrel detent with the at least one flange detent; providing the sliding lock comprising:
a body portion comprising a proximate end, a distal end, two sides, an outer surface and an inner surface;
at least one rail disposed on the inner surface of the body portion;
at least one flexible arm integral with the body portion; and
at least one catch disposed on the at least one arm;
providing the at least one rail within the at least one flange detent and the at least one barrel detent; providing the at least one catch within the at least one recessed portion; and disengaging the catch from the recessed portion and the at least one rail from the at least one barrel detent.
