Description

[0001] APPARATUS FOR TELECOMMUNICATIONS CABLES

[0002] Field of Invention

[0003] The present invention relates to an apparatus for managing telecommunications cables.

[0004] Background

[0005] Telecommunications cables may be wound into a so-called figure-of-eight flakes (also referred to as a “fake” or “fleet’) such an arrangement is advantageous because, compared to spooled cable, both terminal ends of the cable can be unwound simultaneously (for example, at any intervention point of a cable pull) and, with both terminal ends free (and apart), the risk of kinking, twisting or knotting during uncoiling is reduced.

[0006] Telecommunications cables may, however, be constructed in a manner that renders them difficult for a user to manipulate, at least owing to the resilience, weight, elasticity and frangibility of such cables. Accordingly, creating a figure-of-eight flake (also referred to an “fleeting” or “flaking”) from telecommunications cables may in turn require multiple users. Furthermore, equipment (e.g. traffic cones) may be used ad hoc to assist with flaking, but such equipment may cause the telecommunications cable to be damaged, form ineffective flakes, or otherwise be unsuitable for use manipulating telecommunications cables.

[0007] It is an aim of the present invention to at least alleviate some of the aforementioned problems.

[0021] Any apparatus feature may also be provided as a corresponding step of a method, and vice versa. As used herein, means plus function features may alternatively be expressed in terms of their corresponding structure, for example as a suitably-programmed processor.

[0022] Any feature in one aspect of the invention may be applied, in any appropriate combination, to other aspects of the invention. Any, some and / or all features in one aspect can be applied to any, some and / or all features in any other aspect, in any appropriate combination. Particular combinations of the various features described and defined in any aspects of the invention can be implemented and / or supplied and / or used independently.

[0023] As used throughout, the word 'or' can be interpreted in the exclusive and / or inclusive sense, unless otherwise specified.

[0024] The invention extends to an apparatus as described herein and / or substantially as illustrated with reference to the accompanying drawings. The present invention is now described, purely by way of example, with reference to the accompanying diagrammatic drawings, in which:

[0025] Figures 1 a and 1 b show an example of an apparatus for winding telecommunications cable into a figure-of-eight flake;

[0026] Figures 2a and 2b show the apparatus with a wound telecommunications cable in situ;

[0027] Figure 3a and 3b show the apparatus, with the wound telecommunications cable in situ, transformed into a dispensing state;

[0028] Figure 4a and 4b show a further example of an apparatus for winding telecommunications cable into a figure-of-eight flake; and

[0029] Figure 5a and 5b show yet a further example of an apparatus for winding telecommunications cable into a figure-of-eight flake.

[0030] Figures 1 to 5 show an apparatus 100, or guide, for winding telecommunications cable so as to form a figure-of-eight flake 110. Throughout, figures suffixed with an ‘a’ (e.g. Figure 1 a) are side elevation views, whereas those suffixed with a ‘b’ ( / .e. Figure 1 b) show top elevation views. The apparatus 100 comprises: a free-standing base 120; a pair of supports 130, in turn comprising first 130-1 and second 130-2 supports; and an engagement formation 140.

[0031] The free-standing base 120 is a flat, rigid and stable frame for resting on ground, form which the pair of supports 130 each project perpendicularly and are rigidly attached to the base by means of the engagement formations 140.

[0032] Each of the pair of supports 130 are configured to define a structure around, and against, which a telecommunications cable may be tightly wound, and successive windings stacked.

[0033] To do so, in the example of Figures 1 to 3, each support comprises a set of four posts 150, with each post being set around a perimeter of a rectangle and defining a corner of said rectangle. Correspondingly, in an alternative example, as shown in Figures 4, each support is in the form of a cylinder 160. In the example of Figure 5, each support of the apparatus comprises a set of six posts 150, set around a perimeter of the base, and therefore define a rectangular perimeter.

[0034] In each of the examples of Figures 1 to 5, the first 130-1 and second 130-2 supports are arranged apart from one another along the free-standing base, and are separated by free space, such that the telecommunications cable may be alternated between being wound around each support 130.

[0035] The engagement formation 140 for each support is therefore configured to resist compliance of the supports against the tension of the winding of the telecommunications cable.

[0036] Each of the supports 130 is dimensioned to have a height that is many multiples of the gauge of the telecommunications cable; in this way, windings of the telecommunications cable can be stacked to form the flake 1 10, and to allow formation of multiple separate flakes, from separate lengths of telecommunications cable, with the same apparatus 100. For example, the height of each support is 1 meter. Each support 130 also comprises parallel external walls, which allows the flake 100 to have evenly sized lobes across the height of the flake.

[0037] Telecommunications cables may have advised minimum bend radii to help prevent damage. Accordingly, each of the supports 130 are dimensioned and are separated from one another to help prevent, for a given telecommunications cable, bends below the advised minimum bend radii. In the example of Figures 1 to 3 and 5, the rectangles defined by the posts, lie on, or envelope, a notional circle (not shown) defining the minimum bend radius of the telecommunications cable. Correspondingly, in the example of Figure 4, the cylinder 160 lies on, or envelopes, this circle. In use, a single user is available to unspool a length of telecommunications cables and tightly to ‘slalom’ the cable around and between each of the supports, thereby forming the flake 110, as best shown in Figures 2.

[0038] In the specific example of Figures 1 to 3, the apparatus 100 is transformable between a flaking state (as shown in Figures 1 and 2) and a dispensing state (as shown in Figures 3).

[0039] In the flaking state, the posts are rigidly supported in vertical parallel alignment to allow for winding of the telecommunications cable thereagainst, and therefore allow for formation of the flake 110. Once the flake has been formed, a user may bind the flake to ensure it maintains form.

[0040] With reference to Figures 3, each of the posts, for a given support, are pivotable so that an upper free terminal end of each post inclines inwardly toward one another, thereby effectively forming a frame of a pyramid. The movement of the posts in this way transforms the apparatus into the dispending state. To allow for such movement of the posts, the engagement formation for each post comprises an appropriate lockable movable joint (not shown), such as a hinge comprising a locking abutment mechanism. By angling the posts in this way, the posts may be released from abutment against the flake, which in turn allows a user to remove the flake. In a corresponding manner to the example of Figures 1 to 3, the example of Figure 5 is also available to transform between the flaking and dispensing states.

[0041] Alternatives and Modifications

[0042] In an alternative, the apparatus comprises a waist support, arranged between the first and the second supports, which defines an aperture through which to receive and constrain the telecommunications cable at a crossover point (or “waist”) of the flake between each lobe, thereby helping further support the formation of the flake, and limit widening of the waist.

[0043] In an alternative, the lockable movable joint is lockable (optionally, only) by means of a removable brace for receiving, and rigidly interconnecting, the free terminal ends of each support or a plurality of the posts of each support.

[0044] In an alternative to the examples of Figures 1 to 3 and 5, the lockable movable joint allows movement of the posts through ninety degrees relative to the base, such that each of the posts may be laid flat against the base, thereby reducing the overall dimensions of the apparatus for more convenient transportation. Furthermore, the base is available to comprise a hinge along a longitudinal midpoint, thereby to allow for folding-up of the base, and a further reduction in the overall dimensions of the apparatus. Each feature disclosed herein, and (where appropriate) as part of the claims and drawings may be provided independently or in any appropriate combination. Any reference numerals appearing in the claims are for illustration only and shall not limit the scope of the claims.
