Abstract
Abstract A knockdown reel comprising a tubular hub and having a pair of similar end flanges disconnectably attached to opposite ends of the hub by latching means capable of being released in order to separate the end flanges from the hub and thereby minimize the space consumed by said components in packaging, shipping and storing reels of this type. Actuation of the latching means is possible either manually or by relatively simple tools. The hub also may be made of a plurality of separable parts to further facilitate compactly arranging the components for the purposes described.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
A knockdown reel comprising in combination, a tubular hub member, a pair of similar end flange members each having a short sidewall extending axially from the outer surface thereof and complementary in cross-sectional shape to the ends of said hub member and adapted respectively to telescopically engage opposite ends of said hub member, and releasable locking means on the telescopically engaging portions of said hub member and short sidewall of said end flange members comprising yieldable latch elements having radially extending locking abutments thereon arranged at circumferentially spaced locations on the telescopically engaging portions of one of said members and radially extending openings in the telescopically engaging portion of the other member arranged complementarily to receive said locking abutments of said one member and latch the end flange members releasably to the opposite ends of said hub member, said locking abutments being accessible through said radial openings adjacent the outer surfaces of said end flange members for engagement to move said abutments radially in disengaging direction to permit separation of said end flange members from said hub for compact packaging and storage of said reel components.
Claim 2
Dependent Claim
186 words
A knockdown reel comprising in combination, a tubular hub member, a pair of similar end flange members each having a short sidewall extending axially from the outer surface thereof and complementary in cross-sectional shape to the ends of said hub member and adapted respectively to telescopically engage opposite ends of said hub member, and releasable locking means on the telescopically engaging portions of said hub member and short sidewall of said end flange members comprising yieldable latch elements having radially extending locking abutments thereon arranged at circumferentially spaced locations on the telescopically engaging portions of one of said members and radially extending openings in the telescopically engaging portion of the other member arranged complementarily to receive said locking abutments of said one member and latch the end flange members releasably to the opposite ends of said hub member, said locking abutments being accessible through said radial openings adjacent the outer surfaces of said end flange members for engagement to move said abutments radially in disengaging direction to permit separation of said end flange members from said hub for compact packaging and storage of said reel components.
Claim 3
Dependent Claim
31 words
The reel according to claim 1 in which said latch elements are on said hub member and said radially extending openings are in said short sidewalls on said end flange members.
Claim 4
Dependent Claim
41 words
The reel according to claim 2 in which said latch elements are substantially co-extensive in length with the ends of said hub member and comprise tongues defined by pairs of slots extending radially into the opposite ends of said hub members.
Claim 5
Dependent Claim
47 words
The reel according to claim 1 in which said short sidewalls on said end flange members comprise walls defining shallow sockets formed in said members and extending outwardly from the outer surfaces of said end flange members and perpendicularly to the planes of said end flange members.
Claim 6
Dependent Claim
110 words
The reel according to claim 4 in which said sockets further are defined by bottom walls parallel to the planes of said end flange members and disposed outwardly therefrom when said end flange members are connected to opposite ends of said hub member, whereby said short sidewalls defining the circumference of said shallow sockets which extend axially outward from the outer surfaces of said end flange members dispose the radial openings which extend through said sidewalls in positions which readily expose said locking abutments of said latch elements for engagement to depress the same from said openings and thereby permit separation of said end flange members from said hub member.
Claim 7
Dependent Claim
61 words
The reel according to claim 5 in which the depth of said shallow sockets between the outer surface of said end flange members and the inner surfaces of said bottom walls of said sockets is substantially equal to length of said locking abutments of said latch members and said abutments project radially outward beyond the outer surface of said hub members.
Claim 8
Dependent Claim
44 words
The reel according to claim 5 in which said hub member has seat means formed therein at least adjacent opposite ends thereof and said latch members comprising spring metal inserts fastened to said hub member and having locking abutments formed on one end thereof.
Claim 9
Dependent Claim
76 words
The reel according to claim 7 in which said seat means comprise grooves extending axially along the inner surface of said tubular hub member at circumferentially spaced locations and said latch members comprise spring metal strips extending longitudinally within said grooves and the ends of said strips being bent reversely upon the outer surface of said hub member at an acute angle to the outer surface thereof to constitute the locking abutments for said hub member.
