Abstract
Abstract A knockdown reel and a fixture constructed and arranged for use with the reel so that the reel can be disassembled quickly and with ease. The reel has a central tubular hub formed in two halfshell sections and end flange members that are snap-fitted onto the opposite ends of the assembled tubular hub. The fixture has a plurality of axially extending fingers which can be pressed onto one end of the reel to disconnect simultaneously the snap fittings associated with one flange member for quick removal. Similar removal of the flange member at the other end can then be carried out.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
179 words
In combination, a knockdown reel comprising a tubular hub member having at its opposite ends axially extending resilient latch members adapted for simultaneous inward deflection, said latch members having locking abutments projecting outward adjacent to their terminal ends, and end flange members mounted on the opposite ends of said tubular hub member, each of said flange members defining in its central portion a socket, said socket having a dimension for receiving in close fitting mating relation an end of said tubular hub member and having holes in its circumference through which said locking abutments project for locking the flange member on said hub member, and a disassembly fixture having axially extending finger portions corresponding in numbers and spacing to said locking abutments, said finger portions defining an inner circumference corresponding to the inner circumference of said socket so that when the fixture is pressed in an axial direction onto the outer end of said socket the fingers will depress said latch members radially inwardly sufficiently far to permit removal of the end flange member from the tubular hub member.
Claim 2
Dependent Claim
179 words
In combination, a knockdown reel comprising a tubular hub member having at its opposite ends axially extending resilient latch members adapted for simultaneous inward deflection, said latch members having locking abutments projecting outward adjacent to their terminal ends, and end flange members mounted on the opposite ends of said tubular hub member, each of said flange members defining in its central portion a socket, said socket having a dimension for receiving in close fitting mating relation an end of said tubular hub member and having holes in its circumference through which said locking abutments project for locking the flange member on said hub member, and a disassembly fixture having axially extending finger portions corresponding in numbers and spacing to said locking abutments, said finger portions defining an inner circumference corresponding to the inner circumference of said socket so that when the fixture is pressed in an axial direction onto the outer end of said socket the fingers will depress said latch members radially inwardly sufficiently far to permit removal of the end flange member from the tubular hub member.
Claim 3
Dependent Claim
31 words
The combination that is defined in claim 1, wherein said hub member comprises two identical semicircular shells having tongue-and-groove longitudinal edges for securing the shells together to define a cylindrical shape.
Claim 4
Dependent Claim
34 words
The combination that is defined in claim 1, wherein said disassembly fixture comprises a central disk portion and said finger portions are mounted in spaced relation around the outer circumference of said disk portion.
Claim 5
Dependent Claim
63 words
The combination that is defined in claim 1, wherein the holes in said socket are defined by axially extending slots which extend through the base of said socket, and said locking abutments have beveled terminal ends for engagement by the ends of said finger portions for deflection of the latch members radially inward when the finger portions are advanced onto said locking abutments.
Claim 6
Dependent Claim
52 words
The combination that is defined in claim 4, wherein each of said flange members has an annular disk portion projecting radially outward from its socket, and said fingers have an axial length sufficient to engage said annular disk portion when said disasSembly fixture is pressed onto the outer end of said socket.
