Definitions

  • the present invention relates to a lining of a holder for electrical cables such as a cable ladder or the like.
  • the object of the present invention is to provide a new type of lining, which may act as carrier for additional equipment such as lighting fittings and
  • the object is to afford fitters and maintenance staff a lining which facilitates service and mounting and which thereby will be time-saving for such occupational groups.
  • the invention affords a lining which easily can be adapted to varying installation solutions.
  • the invention concerns a lining of a holder for electrical cables, such as a cable ladder or the like.
  • the lining comprises a fastening means, which is arranged to support the lining in a suitable way.
  • the lining comprises furthermore a first cover means, which at its one side is provided with a collar arranged to grip parts of the fastening means.
  • the first cover means is, at its other side, provided with a mounting hook arranged to grip parts of the fastening means.
  • the lining comprises a second cover means, which at its respective sides is identically formed as the first cover means and arranged to be mounted opposed and connected to the first cover means.
  • the cover means are asymmetrical in a cross-section wherein two cover means may be mounted together opposed to each other.
  • the cover means may in this connection be manufactured as a profile, preferably of aluminium, which profile is cut into suitable lengths to form the first cover means and the second cover means.
  • first cover means and the second cover means have identical cross-sections taken perpendicular to the respective longitudinal direction of the cover means.
  • one side of the cover means is provided with a lateral support, which for the first cover means is arranged to abut against said fastening means when the cover means is mounted.
  • the lateral support provides a defined horizontal position or lateral position for the cover means, which facilitates the mounting of the cover means.
  • the other side of the cover means is provided with a bottom support, which for the first cover means is arranged to abut against said fastening means when the cover means is mounted.
  • the bottom support provides a defined vertical position or height position for the cover means, which also facilitates the mounting of the cover means.
  • the collar of the cover means is placed on the outside of a longitudinal, opened groove in the cover means and directed away from the opening of the groove.
  • the opening of the groove and a support seam arranged on the cover means are directed in the same direction.
  • the opening of the groove and the support seam, respectively, are placed on each side of the cover means so that the upper, second, cover means fits in the lower, first, cover means when the cover means are mounted against each other.
  • the mounting hook of the cover means is situated on a mounting arm on which the support seam, essentially perpendicularly to the mounting arm, is formed.
  • the cover means are formed with parallel side edges.
  • This embodiment means that two opposed mounted cover means may have a lining having parallel sides, which implies a simple fitting-in when mounting the lining.
  • These parallel side edges may also constitute mounting surfaces for lightning, illuminated sign, etc.
  • the opening of the groove and the support seam are directed parallel to the side edges. Also this embodiment contributes to the mountability.
  • the support seam of the second cover means abuts against the bottom of the groove of the first cover means and that the bottom of the groove of the second cover means abuts against the support seam of the first cover means when the cover means are assembled.
  • the first cover means is, when the lining is fully mounted, bolted to both sides of the fastening means and the second cover means is solely bolted to the first cover means.
  • the fastening means is formed as a symmetrical profile having a width exceeding the width of the holder for electrical cables on which the fastening means can be mounted, one side of which fastening means is provided with a first mounting bar and the other side of which fastening means is provided with a second mounting bar which two mounting bars are provided with a respective longitudinal slide edge, on which slide edges the first cover means is slidably suspended so as to subsequently be fixed to the fastening means.
  • the cover means is between the sides thereof formed with a surface bulging outward from the holder for electrical cables.
  • a bulging surface is relatively soil repellent and is easy to keep clean upon washing.
  • the invention also concerns a lining of a holder for electrical cables, such as a cable ladder or the like, which lining comprises a fastening means mountable on a holder for electrical cables, one side of which fastening means is provided with a first mounting bar and the other side of which fastening means is provided with a second mounting bar.

  • the first cover means is, at its other side, provided with a mounting hook arranged to grip the slide edge of said second mounting bar.
  • the fastening means is dimensioned to carry extra equipment such as lighting fittings, surveillance cameras, loudspeakers, etc.
  • the cover means is curved to contain such extra equipment. The curvature is formed as a circular sector or as a sector of an ellipse.
  • the cover means is also provided with a lateral support arranged to abut against said first mounting bar. This lateral support acts as an anvil upon mounting and dismounting of the cover means.
  • the other side of the cover means is provided with a bottom support arranged to abut against the second mounting bar when the cover means is mounted.

In a vertical mounting, a lower cover means may then be hanging on the fastening means.
  • the mounting hook of the fastening means is situated on a mounting arm on which a support seam essentially perpendicularly to the mounting hook is formed.
  • the opening of the groove and the support seam on the first cover means are directed in the same direction. This means that two cover means can be mounted against each other for a completely mounted lining.
  • the fastening means is formed as a symmetrical profile.
  • the first cover means is formed with parallel side edges.
  • This embodiment means that two opposed mounted cover means may have a lining having parallel sides, which implies a simple fitting-in when mounting the lining.

  • the two cover means are identical but asymmetrically shaped and may be manufactured as profiles which after manufacture are cut into suitable lengths. Hole making may be made for pendulum suspension, lighting fittings, cameras, loudspeakers, etc.
  • the invention also discloses a method for the opening of a lining formed according to what has been described above by the screws at the side edge of the other side being removed, wherein the first cover means is lifted at said side edge after which the first cover means is displaced out from the fastening means so that the mounting hook can be brought past the second mounting bar and be turned down from the fastening means so that the first cover means will remain hanging at the second mounting bar on the fastening means.
  • simple screws for sheet metal may be used, which are self-tapping. Longitudinal provisions in the form of notches for the screws are made in the profiles.
  • a lining according to the invention is intended to be used in horizontal installations of cable ladders and cable trays in industrial buildings, on office premises and at platforms, but also other fields of application are feasible within the scope of the invention.
