Definitions

  • the present invention relates to an anchoring assembly for anchoring a tensioning wire, cable or rod which runs freely through or along a profile for the purpose of tensioning this profile, and particularly for tensioning a tensioning wire, cable or rod at an end of a horizontal beam of a gate.
  • the invention also relates to a gate, in particular a sliding gate, comprising such an anchoring assembly.
  • tensioning wire will be used below to refer generally to an elongate tensionable means such as a tensioning wire, cable or rod, and the skilled person will thus appreciate that in the context of the present application the term tensioning wire must be given a functional interpretation.
  • NL 8302007 describes a gate (sliding gate or swing gate) with a horizontal beam and a number of vertical bars.
  • the horizontal beam is a tubular profile provided with a series of holes for receiving the vertical bars.
  • a tensioning wire or tensioning rod carried through transverse holes of the bars. Additional tensioning wires or rods are typically further provided in order to contribute toward the stiffness of the beam.
  • One end of each tensioning wire is provided with a head part which is fixed to one end of the tubular profile.
  • the other end of the tensioning wire is provided with tensioning means supporting on an end part mounted in the other end of the tubular profile.
  • the gate is tensioned by the tensioning wire with tensioning means to the extent that the gate no longer "sags". In the case of a sliding gate this is the basis for light running of the gate. In the existing systems there is a risk of danger in the case the wire snaps or breaks loose, since this wire will then typically shoot out of the gate.
  • the present invention has for its object to provide an anchoring assembly of the type stated in the preamble which is safer than the prior art assemblies and which reduces the risk of accidents resulting from breaking of a tensioning wire.
  • the invention provides for this purpose an anchoring assembly of the type stated in the preamble which comprises a tension transmitting part for transmitting a tension in the tensioning wire to the horizontal beam, at least one conical sleeve connected to the tension transmitting part, a wedge for each conical sleeve, and a safety cover.
  • a tensioning wire can be passed through each conical sleeve and clamped by the wedge which can be received in the conical sleeve.
  • the safety cover is adapted for fastening to the conical sleeve and/or to the tension transmitting part over an outer end of the tensioning wire extending through the conical sleeve.
  • the invention can be used particularly to tension a horizontal beam of a gate, but can equally well be used in profiles of other constructions, such as road signs above motorways, and more generally in any construction where a profile must be tensioned in safe manner using at least one tensioning wire running freely through or along the profile for tensioning thereof.
  • the safety cover is adapted to make contact with the outer end of the tensioning wire extending through the conical sleeve.
  • the invention also works in the case there is a small distance between the safety cover and the outer end of the tensioning wire. After all, a wire which snaps will in this case also be unable to develop sufficient speed to break the connection between the safety cover on the one hand and the conical sleeve or the tension transmitting part on the other.
  • the safety cover is provided with an internal screw thread and the conical sleeve is provided with a complementary external screw thread.
  • the safety cover can in this way be screwed onto the conical sleeve.
  • a safety cover could for instance also be provided in the form of a plate which fits over the outer end of the tensioning wire and can be fastened by bolts to the tension transmitting part. In the case of a plurality of tensioning wires this plate could also fit over the outer ends of the different tensioning wires, so providing as it were one safety cover for the plurality of tensioning wires.
  • the tension transmitting part is typically intended for placing against an end of a profile, and preferably comprises a substantially vertical middle leg dimensioned to extend as far as the lower edge of the profile and a substantially horizontal portion connected thereto and dimensioned to extend to the two side edges.
  • An elastic tension in the wire can in this way be properly transmitted to the beam.
  • the tension transmitting part has substantially the form of a T.
  • the horizontal portion is preferably provided with a first end part with a first hole for passage of a first tensioning wire and with a second end part with a second hole for passage of a second tensioning wire, wherein a first conical sleeve is provided on the first end part and a second conical sleeve on the second end part.
  • the anchoring assembly can thus be intended for placing against an open end of a profile, wherein the tension transmitting part is adapted to substantially wholly cover the open end.
  • the or each wedge is a multipart wedge, for instance a two-part or three-part wedge. This has the advantage that the wedge does not have to be pushed over the wire, but can be arranged around the wire close to the desired location, thereby avoiding "scraping" along the wire and "filling" of the wedge.
  • the or each conical sleeve has a first and a second end and a passage for a tensioning wire between the first and second ends, wherein the or each conical sleeve is provided at its first end with screw thread; and the tension transmitting part is provided in each case with a hole with a complementary screw thread.
  • the conical sleeve can in this way be easily fastened with screws to the tension transmitting part.
  • the skilled person will appreciate that other connecting techniques are possible and that the at least one conical sleeve and the tension transmitting part can also be manufactured integrally.
  • the conical sleeve preferably has a conical inner wall between the first and the second ends, the diameter of which decreases from the second end in the direction of the first end.
  • the present invention further relates to a gate with a horizontal beam and a number of vertical bars, wherein the horizontal beam is a tubular profile through which runs at least one tensioning wire.

  • the horizontal beam can be provided with a series of holes for receiving the vertical bars and in the tubular profile an additional tensioning wire can be provided which is carried through transverse holes of the bars.
  • the horizontal beam is assembled from a plurality of mutually connecting tubular profiles.
  • the horizontal beam is a lower horizontal beam and the gate further comprises an upper horizontal beam
  • both the lower and the upper longitudinal beams can each be assembled from a plurality of mutually connecting tubular profiles.

  • Such a centering pin is intended to protrude partially into a first tubular profile and partially into an adjacent second tubular profile.
  • the at least one tensioning wire extends through the plurality of adjacent tubular profiles and clamps the plurality of profiles against each other.
