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.
Claims19
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.
