Definitions

  • This invention relates to roundabouts, traffic islands or the like.
  • Mini roundabouts are becoming a more and more popular method of providing relatively cheap traffic control, but they rely on road users obeying the rules relating to roundabouts and in practice this often proves to be over-optimistic. Frequently drivers will either ignore the roundabout designations completely or take undesirable short cuts across part of the designation. Further it is often desirable to provide traffic islands or roundabouts of particular dimensions to suit a junction but in practice these dimensions are determined by the building elements available.
  • the present invention consists in a roundabout, traffic island or the like, comprising a base and a plurality of elements mounted on or projecting from the base to define the outer periphery of the roundabout.
  • the elements may be in the form of spokes radiating from the base. In either case the base may define respect- ive recesses or tunnels in which the elements can be located.
  • the elements may be made up of one or more portions which may, for example, be interconnected by plug like connectors.
  • the elements may be generally arch-shaped in cross section although their height may diminish along their length.
  • the elements may be extruded.
  • the base may be essentially in the form of a hub and may be cast from concrete, plastics or particularly prefer ⁇ ably reconstituted plastics.
  • the base may be formed in a single part or in a number of interconnectable portions.
  • the present invention consists in a roundabout, traffic island or the like comprising a base and a plurality of elements mounted on the base to define the outer periphery of the roundabout, the elements being mounted for movement relative to the base so that they can progressively project from the base to define outer periph- ery for the roundabout of increasing magnitude.
  • the elements are slidably connected to the base for movement in a generally outward direction.
  • the elements may be generally wedge- shaped in horizontal cross-section, in which case they may be higher at their end nearest to the middle of the base than they are adjacent the end which defines a part of the outer periphery. Frequently there may be gaps between the elements in at least some projected positions so they in effect act as sleeping policemen of increasing severity the more a motorist encroaches the roundabout.
  • the elements may be rotatably mounted on the base in an alternative arrangement and may be particularly conveniently both rotatably and slidably mounted on the base.
  • the elements When the elements are rotatably relative to the base the elements may be generally crescent-shaped and at least part of each element may underline the base. In this arrangement the elements act rather like a camera iris except with the outer periphery increasing in dimension.
  • the roundabout may include means for fixing the elements relative to the base once the desired periphery has been achieved. This may include means for securing the elements and/or the base to the road surface.
  • Figure 1 is a plan view of one embodiment of a round ⁇ about with elements shown in different operational posi- tions;
  • Figure 2 is a section of the roundabout of Figure 1 along the line A-A;
  • Figure 3 is a section of the roundabout of Figure 1 taken along the line B-B;
  • Figure 4 is a view from below of the base of the roundabout of Figure 1;
  • Figure 5 is a plan view of an alternate form of a roundabout in accordance with the invention.
  • Figure 6 is a section of the roundabout of Figure 5 along the line C-C.
  • Figure 7 is a side view of a base of a roundabout
  • Figure 8 is an exploded view from above of a roundabout incorporating the base of Figure 7;
  • Figure 9 is a side view of an alternative base;
  • Figure 10 is a plan view of the base of Figure 9;
  • Figure 11 is a side view of a further form of base
  • Figure 12 is a plan view of the base of Figure 11.
  • a roundabout 10 comprises a central base portion 11 and a plurality of skirt elements
  • the skirt elements are connected to the base by means of bolts 13 which pass through radial slots 11a in the base.
  • skirt elements 12 project from the base portion 11 depends in part on the radial position of the respective bolts 13 in its slot and partly on the rotational position of the skirt element 12 relative to the base portion 11. By appropriate selection of these radial and rotational positions the skirt elements 12 can be located to define a range of outer peripheries 14. As can be seen in Figure 1 skirt elements 12a to 12c are in positions in which they project significantly from the base
  • skirt elements 12 Once the skirt elements 12 have been laid out in the desired position, they can be secured to the base and the ground by means of bolts 13 and they may also be secured to the ground and/or each other by means of bolts 15 which act close to their tips 16.
  • the base 11 has a raised central portion 17 so as to provide a physical obstacle to drivers. This could also serve as a flower pot or bed and may carry reflective signs on its outer surface.
  • a kerb 17a may also be provided.
  • FIG. 5 and 6 an alternative form of roundabout is shown at 18. This has a base 19 on which are slidably mounted a number of wedge elements 20. Conveni ⁇ ently the wedge elements may be supported on T-section extrusions 21. In use the outer periphery 18a of the roundabout 19 can be altered simply by radial movement of the wedge elements 20. As can be seen in Figure 5 the wedge elements are highest nearest their narrow inner ends 22 and lowest nearest their outer edges 23.
  • the space 25 in the centre may be filled with a raised central portion, as in the preceding embodiment, or it may be free so that the wedges can collapse back to entirely overlie the face.
  • the base and wedge elements can be bolted to the road surface as before. Additionally or alternatively appropriate adhesives may be used.
  • the central base portion 11 is formed with a series of circumferentially spaced recesses 26 into which spoke like elements 27 can be inserted to define a roundabout 10.
  • the spoke like elements 27 may be further extended by additional elements 28 connected longitudinally with the elements 27 by a plug like connector 29.
  • additional elements 28 connected longitudinally with the elements 27 by a plug like connector 29.
  • any desired roundabout periphery can be achieved.
  • the advantage of this arrangement is that it is easier to manufacture and slightly less complex in use.
  • the base 11 once again has a raised central portion 17 and may be cast in any appropriate material such as con ⁇ crete, glass reinforced plastics or reconstituted plastics. It may be cast as a single element or in a number of interconnectable pieces.
  • the elements 27, 28 and plug 29 may be extruded and may be formed in any of these materials.
  • Figures 9 and 10 and 11 and 12 illustrate alternative constructions of the central base unit 11.
  • the recesses 26 are in the form of tunnels providing good accurate location of the spoke like elements 27.
  • these units may be cast in two portions so that the central raised portion 17 is one part and a bottom portion 30 is the other part.

Abstract

L'invention se rapporte à différents modes de réalisation de ronds-points (10) qui comprennent des éléments (12, 20 ou 27) faisantsaillie à partir d'une base (11, 19) pour définir le pourtour externe du rond-point. Ces ronds-points (10) peuvent particulièrement être utilisés comme rond-points temporaires ou mini-rond-points.
