Abstract

The reel includes a certain number of sectors (1) each formed by a single piece of bent wire, the sectors being joined together by welding. Each sector includes two inner peripheral edge sections (6a) extending along a circumference and axially spaced apart, these interacting in order to form two hub rings (11a) intended to allow the reel to be mounted on a shaft. A reel made of wire, fitted with a hub, is thus produced in a simple manner.

Description

The present invention relates to reels for the storage of filamentary material, e.g. wire.

Patent Specification No. 42586 is concerned with a reel for the storage of filamentary material, which comprises a plurality'of elements each made of a single piece of wire bent to form a sector of the reel and all secured together in a circular array, - In one embodiment the application discloses a reel in which the radially innermost portions of at least some of the elements are secured to a pair of central bearing rings for the reel.

According td the present invention there is provided a reel. for-.the storage of filamentary material, comprising a plurality of elements each made of a single piece of wire bent to form a sector of the reel and all secured .together in a circular array, in which each element has, in relation to the reel axis, two axially spaced circumferentially extending inner rim portions at . the radially innermost regions thereof, all of said inner rim portions of the respective element co-operating to define two axially spaced bearing rings for mounting the reel on a shaft.

It will be appreciated that such an arrangement has the advantage that all of the elements can be inter25 connected by spot-welding, particularly in the regions -4 6363 - 3 thereof where the filamentary material is wound in use . The reel can be so formed that no cut ends of wire or welding burrs such as result from butt-welding are located where they might injure a user or damage the material to be stored on the reel.

Some embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a reel element made from a single length of wire; Figure 2 is a side elevation of a reel constructed from a plurality of the elements of Figure 1; Figure 3 is a cross-section on line III-III of Figure 2; Figure 4 is a view similar to Figure 1 showing another embodiment of reel element; Figure 5 is a cross-sectional view similar to Figure 3 of a reel constructed from the elements of Figure 4.

Figure 1 shows a three dimensional element made from a single piece of metal wire. The element has two arcuate outer rim portions 2a, 2b which are arranged side by side and, in the constructed reel, form portions of the outer rims of the reel. Each rim portion 2a, 2b has a first side member (3a, 3b respectively) extending, in relation to the axis of the constructed reel, radially inwardly: a transverse member 4, which, in use, supports filamentary material wound on the reel, extends between the said side members. At the other ends of the outer rim portions are second and longer side members 5a, 5b which also extend radially inwardly, at an angle of 45° to the side members 3a, 3b. From the radially inner ends of the side members 5a, 5b extend respective arcuate inner rim portions 6a, 6b, generally parallel to the rim portions 2a, 2b and which terminate in radially outwardly 6365 -4-extending stubs 7a, 7b collinear with the side members 3a, 3b respectively.

The element 1 may conveniently be made by bending a planar 0-shaped loop of wire.

Figures 2 and 3 show a reel constructed from eight elements 1 joined together in a circular array. The outer rims of the reel, made up of arcuate rim portions 2a, 2b, are circular: elements having straight rim portions could, if desired, be used, thus forming a polygonal shaped reel. The side member 5a of each element is joined by welds 8a, 9a to the side member 3a, and by a weld 10a to the stub 7a, of an adjacent element. The welds 8a, 9a are preferably spot welds to minimise the possibility of damage to material stored on the reel. The side members 5b, side members 3b and stubs 7b are joined in the same manner. Thus, in the completed reel, the transverse members 4 form a ring of members around which the filamentary material can be wound. The inner rim portions 6a (and similarly the portions 6b) together form a continuous ring Ila, the two rings forming a central bearing for mounting of the reel on a shaft.

The element shown in Figure 4 is similar to the element of Figure 1 (like reference numerals being used for like parts) but the stubs 7a, 7b have, relative to the axis of the constructed reel, axially extending portions 12a, 12b which are butt-welded together as at 13 to form a further transverse member 12. Such an element may conveniently be made by bending an initially planar rectangular wire loop.

A reel constructed from eight elements as shown in Figure 4 is shown in Figure 5; it will be appreciated that the transverse members 12 provide additional rigidity to the structure,particularly in the region of the bearing rings.

Claims

1. CLAIM Si1. A reel for the storage of filamentary material, comprising a plurality of elements each made of a single piece of wire bent to form a sector of the reel and all secured together in a circular array, in which each element has, in relation to the reel axis, two axially spaced circumferentially extending inner rim portions at the radially innermost regions thereof, all of said inner rim portions of the respective elements co-operating to define two axially spaced bearing rings for mounting the reel on a shaft.

2. A reel according to claim 1 in which each element is formed to provide two mutually opposed portions of respective outer rims of the reel, first and second side members extending radially inwardly from respective ends of each outer rim portion, and an axially extending transverse member between the first side members to form a supporting member for the filamentary material, the said inner rim portions extending from the radially innermost ends of the second side members.

3. A reel according to claim 2, in which each inner rim portion has, at its end remote from its respective side member, a radially outwardly extending stub member, each stub member being secured to the said second side member of an adjacent element whereby the inner rim portions are joined together to define said bearing rings.

4. A reel according to claim 3 in which each element includes a further transverse member extending between the radially outer ends of the stub members of that element.

5. A reel for the storage of filamentary material substantially as herein described with reference to Figures 1, 2 and 3 of the accompanying drawings.

6. A reel for the storage of filamentary material substantially as herein described with reference to Figures 4 and 5 of the accompanying drawings.
