Definitions

  • the present invention relates to cable management and is concerned particularly with cable management under raised floors.
  • cable trays tend to be relatively expensive, difficult to cut and fit, provide no cable management, and time consuming to install.
  • Preferred embodiments of the present invention aim to provide cable management devices in raised floor systems, which may be improved in the foregoing respects.
  • a raised floor system with cable management comprising a plurality of supports; a plurality of flooring elements supported on said supports; and an array of elongate members supported by said supports below the flooring elements, each of the elongate members being formed with transverse slots, each of the slots opening into a face of the respective elongate member and comprising two portions that are relatively wide and narrow such that, in use, a cable introduced into the slot from said face passes through the narrow portion to enter the wide portion.
  • said wide portions are of substantially circular cross-section and said narrow portions have substantially parallel walls.
  • at least some of said slots are provided with means to inhibit withdrawal of cables from the slots.
  • said slots are arranged in distinct groups.
  • said groups are distinguished by at least one of slot size, spacing between the groups, colour and labelling.
  • At least one of said elongate members may further comprise at least one transverse slot of a size suitable to accommodate a water pipe.
  • a system according to any of the preceding aspects of the invention may further comprise a bracket adapted to fit over and be supported by one of more of said elongate members, the bracket providing support for a pipe or cable.
  • said bracket comprises at least one of a hole and a channel to support a pipe or cable.
  • said array comprises first elongate members extending in a first direction and second elongate members extending in a second direction transversely of the first direction.
  • said first elongate members are of a common first length and said second elongate members are of a common second length that is shorter than said first length.
  • a system as above further comprises joining means arranged to join two or more of said devices end to end and/ or transversely or
  • said support means are of adjustable height.
  • the invention also extends to a method of constructing a raised flooring system, comprising the steps of connecting together a plurality of elongate members of predetermined lengths to form an array, with a plurality of legs connected to the elongate members in predetermined positions such that the array defines the locations of the legs; and supporting flooring elements on said legs.

  • FIGs 18 and 19 illustrate an alternative support bracket to that shown in Figures 15 to 17.
  • a cable management device 2 is integrated into a raised flooring system 1.
  • the cable management device 2 comprises an elongate member 20 that engages with adjustable legs 3, each of which has a floor plate 31 at a lower end and a tile acceptor plate 32 at an upper end.
  • Lock nuts 33 engage with the elongate member 20.
  • Tiles 4 e.g. of a standard 600 x 600 mm size
  • the elongate member 20 will be referred to as a spar.
  • the spar 20 is formed with a first group D of transverse slots 21 and a second group P of transverse slots 22, spaced from the first group D.
  • the slots 21 and 22 extend orthogonally of the spar 20 and open into an upper face of the spar 20.
  • Each of the slots 21 comprises a relatively wide portion 211 of substantially circular cross-section and a relatively narrow portion 212.
  • An optional nonreturn flap 213 is provided at the bottom of each narrow slot portion 212.
  • the slots 21 are designed to accept data cables. As shown in Figure 2, a data cable 6 is simply dropped into a slot 21 and falls under gravity through the narrow slot portion 212 into the wide slot portion 211 , where a number of cables 6 may collect.
  • the non-return flap 213 prevents accidental removal of cables 6 from the slot 21 , but may be depressed manually so that a cable 6 may be removed if desired.
  • four parallel slots 21 are provided in the group D, but any number may be provided. Marking (e.g. by colour and/ or labelling) may indicate that the group D of slots 21 are suitable for data cables.
  • the slots 22 are similar to the slots 21, comprising a relatively wide portion 221 of substantially circular cross-section, a relatively narrow portion 222, and an optional non-return flap 223. However, they are of a larger size, suitable for power cables, which are introduced into the slots 22 in a similar way.
  • three parallel slots 22 are provided in the group P, but any number may be provided. Marking (e.g. by colour and/ or labelling) may indicate that the group P of slots 22 are suitable for power cables, and distinguish them from the group D.
  • an enlarged slot 23 which is of a size suitable to accept water pipes or other larger items. Like the other slots, it has a relatively wide portion 231 of substantially circular cross-section, a relatively narrow portion 232, and an optional non-return flap 233.
  • the wide slot portions 211 may have a diameter of 35 mm and the narrow slot portions 212 a width of 10 mm.
  • the wide slot portions 221 may have a diameter of 45 mm and the narrow slot portions 222 a width of 18 mm.
  • the spar 20 may be of any desired length. For example, for use with 600 mm square floor tiles, it may be 3000 mm long. A plurality of such spars 20 may be used to build up a raised floor system very quickly and efficiently.
  • a plurality of shorter elongate members that are similar to the spars 20 are provided, with groups of slots such as D and P and optionally larger slots such as 23, and these will be referred to in the following as stringers.
  • the stringers may be 600 mm long.
  • Spars 20 and stringers are preferably joined together in an array, with the stringers orthogonal to the spars 20. With spars 20 and stringers of modular sizes, the array defines the positions of the legs 3 with accuracy, such that tiles 4 and finished flooring 5 may quickly be installed.
  • Figure 3 illustrates diagrammatically a conventional way of installing a raised floor. Legs 3 are installed individually at uniform intervals to make up a grid. Tiles 4 are then supported on the legs 3 and the finished floor laid on the tiles 4.
  • each leg 3 has to be individually measured and each leg 3 individually secured to the base floor, installation is time consuming.
  • one spar 20 and two stringers 27 are initially set in position. The remaining spars 20 and stringers 27 are then joined to them to make an orthogonal array, which fixes the respective positions of all of the spars 20 and stringers 27 and therefore the legs 3. If desired, once all of the legs 3 are in position, one or more of the stringers may be removed. In this option, the stringers 27 need not be provided with slots such as 21 and 22.
  • FIGS 5 and 6A illustrate a 4-way joining bracket 7.
  • Each spar 20 and stringer 27 has a pair of locating notches 201 formed adjacent each end.
  • the bracket 7 has a respective pair of sprung arms 71 to receive each spar 20 or stringer 27.
  • a locating ridge 72 is formed at the end of each arm 71.
  • ends A and B of spars have been engaged by the bracket 7, to join the spars end to end.
  • Stringer C has been engaged by the bracket 7, to extend
  • Bracket 7 includes a top-hat locator pin 73, with which a leg 3 may engage to locate the leg 3 accurately.
  • Figure 6 A shows two spars joined end to end
  • Figure 6B shows a corresponding arrangement where stringers 27 may by joined to a spar 20, part way along the spar 20.
  • brackets 7 shown in Figures 6A and 6B afford four-way joins, variations of the brackets 7 may provide two-way and three-way joins.
  • the modular lengths of the spars 20 and stringers 27 may take into account the dimensions of joining brackets such as the brackets 7. For example, they may be slightly less than 3000 mm and 600 mm respectively.
  • Figure 7 illustrates an array of spars 20 and stringers 27, joined by joining brackets 7.
  • Stringers 27 can be added as and where required to improve stability and for accuracy of spacing.
  • Figure 8 shows three stringers 27 connected together to form an 1800 mm length.
  • the spars 20 and 27 stringers may be of any suitable material. They may conveniently be moulded from recycled plastics materials. Though preferably of modular lengths, they may be sawn or otherwise cut to desired lengths - for example, at the edges of a flooring system, to fit the available floor area.
  • Figures 9 to 11 show a bracket 8 with a hole 81 for supporting a pipe or cable 82.
  • the bracket 8 has a rectangular section to engage closely over a spar 20, the upper surface of which carries felt 83.
  • Figures 12 to 14 show a cable tray 9 that extends between parallel spars 20, on which it is supported by brackets 91 that engage the spars 20 at locations spaced from cable slots 21 , etc.
  • the cable tray 9 is provided with separators 92 such that cables can be separated into groups.
  • the cable tray 9 may also carry pipes and other items.
  • Figures 15 to 17 show a bracket 10 that may be attached to legs 3 of an existing flooring system by cable ties 102 or other securing means, which engage flanges 101 on the bracket 10.
  • the bracket 10 affords a slot 103 to receive a spar 20 or stringer 27.
  • a cable management system comprising spars such as 20 and stringers such as 27 may be retro-fitted to an existing raised floor system.
  • a bracket 11 has a top flange 111 that is formed with a hole 112. Top plate 32 is removed from leg 3, with which the bracket 11 engages, with the leg 3 passing through hole 112. The flange 111 is fixed in position on the leg 3 by nuts 33 and the top plate 32 is replaced. A lower flange 114 engages the leg 3 to keep the bracket 11 substantially vertical. The bracket 11 affords a slot 113 to receive a spar 20 or stringer 27. It may be appreciated that flooring and cable management systems as illustrated and described above may have numerous advantages. Both floor and cable installation time may be reduced. There may be greatly reduced EMI risk, due to cable separation. High static & dynamic mass loading may be achieved. The cable management system may provide increased reliability. It may be lightweight, requiring no special tools or handling, with little or no maintenance required, affording reduced fire risk and being environmentally friendly
