Claims
- 1. A reel for a chain or the like comprising a core portion adapted to have a chain wound around it and a pair of flange portions arranged at opposite ends of the core portion for retaining the chain on the core portion, wherein the reel has an axis of rotation, the core and flange portions are constituted by a pair of bent rods bonded together, wherein the number of bent rods in the reel is limited to two, and wherein each bent rod comprises at least two substantially parallel core-forming elements spaced from each other, the two substantially parallel core-forming elements of each bent rod being spaced from and arranged substantially parallel to the two substantially parallel core-forming elements of the other bent rod, the core-forming elements, proceeding circumferentially around said axis, being in sequence, the two core-forming elements of one rod followed by the two core-forming elements of the other rod, and the four core-forming elements being equally spaced from said axis, whereby the core of the reel comprises at least four substantially parallel, spaced core-forming elements, in which each of said bent rods is closed upon itself to form a continuous closed loop and in which each of said bent rods has flange-forming elements at both ends of the core portion, the flange-forming elements at each end of the core portion connecting one end of one of the core-forming elements to one end of the other core-forming element.
- 2. A reel according to claim 1 in which the flange-forming elements at the end of each bent rod include outwardly extending elements on opposite sides of the core axis aligned with each other along an axis which approximately intersects the core axis, the said outwardly extending elements of each bent rod being in abutting relationship with, and bonded to, corresponding outwardly extending elements of the other bent rod.
- 3. A reel for a chain or the like comprising a core portion adapted to have a chain wound around it and a pair of flange portions arranged at opposite ends of the core portion for retaining the chain on the core portion, wherein the reel has an axis of rotation, the core and flange portions are constituted by a pair of bent rods bonded together, wherein the number of bent rods in the reel is limited to two, and wherein each bent rod comprises at least two substantially parallel core-forming elements spaced from each other, the two substantially parallel core-forming elements of each bent rod being spaced from and arranged substantially parallel to the two substantially parallel core-forming elements of the other bent rod, the core-forming elements, proceeding circumferentially around said axis, being, in sequence, the two core-forming elements of one rod followed by the two core-forming elements of the other rod, and the four core-forming elements being equally spaced from said axis, whereby the core of the reel comprises at least four substantially parallel, spaced core-forming elements, in which one of the core-forming elements of each bent rod comprises a single rod element and the other core-forming element of the same bent rod comprises a pair of parallel rod elements, adjacent to each other but spaced from said single rod element, and in which each of said bent rods has flange-forming elements at both ends of the core portion, the flange-forming elements at each end of each bent rod comprising a reinforming element directly connecting one end of the single rod element to an end of one of the parallel adjacent rod elements.
- 4. A reel according to claim 3 in which, in each bent rod, said single rod element, said one of the parallel adjacent rod elements and said reinforcing elements form a closed loop.
