Definitions

  • the invention relates to a method of manufacturing an elongated carrier for a movable gate intended for closing a passage, whereby the carrier functions to support railings or the like closing means forming part of the gate as well as to connect said gate to a support anchored with respect to the ground, relative to which the gate is movable.
  • a gate which is provided with a carrier, which is made up of a single beam, in which pretensioned wires are provided, by means of which a pressure load is applied to the beam in order to prevent vertically downward deflection of the beam.
  • the carrier is built up of two vertically spaced-apart beams extending parallel to each other, whereby a stress is first set up in at least one of the beams, whereupon the stressed beam is fixedly connected to the other beam by means of plate-shaped parts symmetrically positioned on either side of the beams, said parts are spaced-apart, at least over part of their height, by a distance which is larger than the width of the beams, after which the stress of the stressed beam(s) is released.
  • the carrier When at least one of the beams is correctly stressed the carrier thus obtained will be slightly concave after the stress is released.
  • the carrier Upon assembly of the gate it is then possible to arrange that the carrier is positioned in such a manner that the centre of curvature of the slightly concave carrier is located vertically above the carrier. If the carrier should slightly sag under the influence of the weight of the gate, the carrier will take up an at least substantially horizontal position, so that a light-weight an yet easily operated gate has been obtained. It is thereby possible to manufacture the carrier under optimal circumstances, for example in an air-conditioned room, so that the carrier is capable of optimally meeting the requirements made.
  • the completed carrier does not contain any pretensioned wires or the like, whilst the work which needs to be carried out on the site where the gate is to be placed is reduced to a minimum.
  • the plate-shaped parts of the carrier thereby provide the required stiffness in horizontal direction as well as a good torsional stiffness.
  • a further aspect of the invention relates to a gate for closing a passage, whereby the gate is provided with a carrier and with railings or the like closing means connected to said carrier, whilst the carrier movably couples the gate to a support anchored with respect to the ground by means of runners connected to said support, in such a manner that the gate can be opened and closed by moving the carrier relative to the support.
  • a gate of this type which is known from EP-A-0 128 248, comprises a single prestressed beam, which is supported by runners which are eccentrically arranged with respect to the beam. This results in a disadvantageous loading of the beam, which has an adverse effect on the running qualities of the gate, i.e. the opening and closing of the gate.
  • the carrier is built up of two vertically spaced-apart beams extending parallel to each other, which are interconnected by means of plate-shaped parts symmetrically positioned on either side of said beams, said parts being spaced-apart, at least over part of their height, by a distance which is larger than the width of the beams, whilst the runners are mounted on the support in such a manner, that said runners roll on the upper side of the upper beam and on the bottom side of the lower beam respectively.
  • Figure 1 is a perspective view of a part of a carrier for a gate according to the invention, with a few railings connected thereto and a few runners guiding the carrier.
  • Figure 2 is a larger-scale cross-sectional view of Figure 1.
  • Figure 1 shows part of a carrier 1 arranged horizontally in use, said carrier together with the vertical railings 2 connected thereto forming a gate, in a similar manner as described in the aforesaid European Patent No. 0 128 248.
  • a gate which can be opened and closed the carrier is guided by a plurality of runners 3 secured to supports anchored in the ground, a few of said runners being shown in Figures 1 and 2.
  • a support of the movable gate of this type reference may be made to the aforesaid European Patent No. 0 128 248, which is why it is not considered necessary to discuss this in more detail herein.
  • the carrier is provided with two beams 4 and 5, one being positioned directly above the other, which are of rectangular section in the illustrated embodiment and which are arranged in such a manner that their long sides extend vertically.
  • each of said plate-shaped parts 6 and 7 is built up of a vertically extending plate portion 8, which is joined at its upper edge by a plate portion 9 sloping upwards in the direction of the beam 4, whilst each plate portion is joined at its lower edge by a plate portion 10 sloping downwards in the direction of the beam 5.
  • a double-folded plate portion 11 joins the upper edge of the plate portion 9 remote from the plate portion 8, said plate portion 11 abutting against one side of the upper beam 4.
  • a double-folded plate portion 12 joins the lower edge of the plate portion 10 remote from the plate portion 8, said plate portion 12 abutting against one side of the lower beam 5.
  • the plate-shaped parts 6 and 7 are fixed to the upper beam 4 by securing the double-folded plate portions 11 to the beam 4 by means of rivets or the like.
  • the lower double-folded plate portions 12 are fixed to the lower beam 5 by means of rivets or the like.
  • bars 13 are provided between the beams 4 and 5 in order to keep the beams 4 and 5 the desired distance apart, in particular during assembly of the carrier 1.
  • the ends of the bars 13 may for example be threaded and be screwed into corresponding threaded holes provided in the beams 4 and 5.
  • the bars 13 with shoulders (not shown), which abut against the boundary surfaces of the beams 4 and 5 facing each other, whilst the ends of the bars 13 extending beyond said shoulders are inserted into corresponding holes provided in the beams 4 and 5.
  • a stress will be set up in at least one of the beams 4 and 5, preferably a tensile stress in the upper beam 4.
  • the beam 5 will be mounted at the desired distance from the beam 4 by interposing the bars 4, whereupon the beams 4 and 5 are interconnected by securing the plate-shaped parts 6 and 7 to the beams 4 and 5.
  • the tensile stress on the beam 4 may be released.
  • the carrier thus formed will tend to become slightly concave, in such a manner that the centre of curvature of said hollow carrier, seen in Figures 1 and 2, will be located above the carrier.
  • the carrier which is only supported near one end, at least in certain positions, will tend to deflect slightly under the influence of the weight of the gate, which will eventually result in a substantially straight position of the carrier.
  • Another possibility to achieve a similar effect is to apply a pressure load to the beam 5 prior to assembling the beam 5 and the beam 4 into a carrier in the above-described manner.
  • a third possibility is to apply a tensile load to the beam 4 as well as a pressure load to the beam 5 before interconnecting the two beams 4 and 5 in the above-described manner in order to form the carrier 1.
  • Both the beams 4 and 5 and the plate-shaped parts 6 and 7 may be made of steel. It is possible thereby to use zinc-plated sheet material for producing the plate-shaped parts 6 and 7, which sheet material is coated with a coating of a desired colour.
  • the beams 4 and 5 zinc-plated sections may be used, on which the runners 3 roll. Wear-resistant running surfaces for the runners are thereby obtained, namely shining borders formed by the parts of the beams 4 and 5 extending beyond the plate-shaped parts 6 and 7, which in combination with the coloured plate-shaped parts 6 and 7 may lead to a beautiful aesthetic effect.
  • the construction of the carrier is such that it is very strong and readily made of steel, as a result of which an economical manufacture of the carrier can be realized.
