Definitions

  • This invention is concerned with traffic bollards, particularly as are used to delineate hazards on roadways.
  • a base suitable for use, in conjunction with a marker comprising a reflective display area and a stem portion, in the provision of a traffic bollard, the base being flat and generally rectangular in plan, and being provided with a location slot into which the stem portion of a marker may be located in a manner such that, with the base flat on the ground, the marker extends generally upwardly therefrom, wherein the base is provided with securing means to restrain the stem portion of a marker, when inserted into the location slot, against removal from the base, and release means to move the securing means to a release position.
  • the securing means is resilient, permitting insertion of the stem portion into the location slot but subsequently restraining removal therefrom.
  • the release means comprises an area on the base which is so constructed as to enable it to be engaged by foot pressure and moved to a release position.
  • the securing means comprises a member or a protrusion which in a rest condition of the securing means engages the stem portion of a marker to restrain separation.
  • Such restraint may be effected e.g. by movement of the member or protrusion into a recess in the stem portion or by frictional engagement with the member or protrusion.
  • the securing means is such that the restraint it provides to movement of the stem portion of the marker out of the location slot is relatively small, desirably being at a level such that the combination of base and marker may be picked up and moved from place to place as a whole by holding of the marker, and in addition at a level such that the marker will not be moved from the base by wind pressure, but desirably at a sufficiently low level that, should the marker be hit by a passing vehicle, the stem will be removed from the location slot in preference to the base being overturned.
  • the probability is that all that will happen is that the marker itself will be removed, and being flat will tend to lie on the road surface without causing any significant danger, whilst the base will tend to remain in position.
  • a base suitable for use, in conjunction with a marker comprising a reflective display area and a stem portion, in the provision of a traffic bollard, the base being flat and generally rectangular in plan, and being provided with a location slot into which the stem portion of a marker may be located in a manner such that, with the base flat on the ground, the marker extends generally upwardly therefrom, wherein a side margin of the base lies when the base is placed on the ground at a small acute angle thereto, preferably in the order of 30° or less, said side margin being painted or coated with a material which provides a relatively high coefficient of reflectivity compared with the remainder of the base, as may be attained by painting said side margin white or yellow, or applying thereto white or yellow strip, in both cases preferably light reflective agents such as "ballotoni" being utilised.
  • the base member in addition to providing support for a marker as specified, provides part of a reflective line (white or yellow) which may be located between the traffic lane and the marker, the side margin providing in addition a sloping surface which tends to reduce tendency for the base to be displaced on being mounted or struck by the wheels of a passing vehicle.
  • a reflective line white or yellow
  • a base suitable for use, in conjunction with a marker comprising a reflect ive display area and a stem portion, in the provision of a traffic bollard, the base being flat and generally rectangular in plan, and being provided with a location slot into which the stem portion of a marker may be located in a manner such that, with the base flat on the ground, the marker extends upwardly therefrom, wherein the base is provided on opposites end regions thereof with location means to enable the base to be interfitted with an adjacent base in a manner such as both to facilitate mutual alignment of the two bases and to reduce tendency for subsequent displacement of one relative to the other.
  • Such location means may be provided e.g. by male formations or female formations, such that one base member having male formations is located adjacent to a similar base member having interfitting female formations.
  • the base is provided on one side edge with a male formation and on the other side edge with a female formation so that identical bases may be interfitted into a continuous array.
  • the location means is such that to enable limited articulation between adjacent bases, so as to enable the bases to be arrayed in a curved line.
  • the location means is constructed and arranged so as to enable adjacent bases to be interfitted by verticial movement of one base towards a base which is in a desired position on the road surface, whereby disengagement between adjacent bases may be achieved by vertically upward movement of one of the bases.
  • the number of adjacent bases which are in consequence disturbed may be limited.
  • the location means is also such as to facilitate some degree of "self-centering" of one base as it is lowered vertically towards an existing base in position on the road surface.
  • the base in plan view is non-square, and has slides of large dimension which are approximately 50% larger than sides of smaller dimension, the location slot extending generally parallel to the sides of smaller dimension between the sides of larger dimension and being located closer to one of the sides of larger dimension than the other, preferably being closer to the side on which the reflective surface is provided.
  • a relatively close spacing of markers may be provided: however if desired a greater difference may be utilised to provide a more elongate base, thus to provide a wider spacing of markers.
  • each base may be provided with two location slots to enable each base to carry two markers.
  • a base suitable for use, in conjunction with a marker comprising a reflective display area and a stem portion, in the provision of a traffic bollard, the base being flat and generally rectangular in plan, and being provided with a location slot into which the stem portion of a marker may be located in a manner such that, with the base flat on the ground, the marker extends generally upwardly therefrom, wherein the location slot is located closer to one side of the base than an opposite side.
  • the base above described is particularly useful for markers having a display area which is generally triangular, having a bottom edge from which the stem portion extends and an apex, enabling when the stem portion of the marker is inserted into the slot, conveniently vertically downwardly, a generally conventionally warning triangle to be made visible.
  • the marker is generally planar at least over the majority thereof, and is preferably of the kind known as a "FLATCONE" (Trade Mark).
  • the marker may however be p rovided with reinforcing and/or stiffening ribs as may be desired.
  • the construction and arrangement of the marker is such that it may flex about a line between the stem portion and display area preferably through 90°. In this manner should a linear array of bases and markers be over run by a vehicle, the markers will be momentarily deflective against the bases, but will thereafter return to their vertical position.
  • a traffic bollard comprising a base member as above defined, in combination with such a marker.
  • the bollard which is the preferred embodiment of this invention comprises a generally flat base 6 which is generally rectangular in plan, the base being non-square and having sides 8 a , 8 b which are longer than sides 10 a , 10 b by approximately 50%.
  • the edge margin 12 adjacent to the side 8 b is chamfered, and extends at a small acute angle A which is preferably less than 30°, desirably in the order of 15° to 20°, to the plan of the underside of the base, the margin 12 being coated with a strip of white reflective material.
  • a location slot 14 Provided generally centrally between the sides 10 a and 10 b is a location slot 14, the location slot being closer to the side 8 a than the side 8 b , although being located generally mid-way between the sides 8 a and the commencement of the chamfered edge margin 12.
  • the bollard which is the preferred embodiment of the invention comprises, in addition to the base 6, a warning display device or warning marker 16 of the kind known as a "FLATCONE", the marker comprising a generally triangular display area 18, and a stem 20 extending from the bottom edge of the display area integrally therewith.
  • the marker 16 With the base lying flat on the ground, the marker 16 may be mounted thereon by downward insertion of the stem portion 20 into the location slot 14, so that the marker extends generally vertically upwardly from the base.
  • the marker has one side 16 a thereof which is plane, and which is provided with a coating of highly reflective material, and is provided with a peripheral reinforcing rib 17.
  • the base is provided with location means, provided by a male formation 22 on the side 10 a , and a female formation 24 on the side 10 b .
  • location means provided by a male formation 22 on the side 10 a
  • a female formation 24 on the side 10 b may be located adjacent to one another in a manner such as to ensure general alignment, to provide a linear array of markers 16 adjacent to which a generally continuous reflective line afforded by the edge margins 12.
  • side edges of one of the formations, conveniently the formations 22, are vertically tapered, so that a base may be dropped over an existing base positioned flat on a road surface, and will be centered on the existing base as it moves into position.
  • the formations 22 and 24 are not an exact fit, and are constructed to enable adjacent bases 6 to be relatively articulated to a small extent to enable the line afforded by the bases to be formed into a shallow curve, where this is necessary.
  • the interfitting is such as to enable an array of bases to be aligned on a curve having a radius in the order of the maximum curvature permitted, typically of 200 metres or less.
  • the base 6 is moulded of rubber, and is provided on its under surface with a number of ribs 30 to provide a necessary degree of rigidity, whilst allowing the base to be manufactured at relatively low weight.
  • the base Adjacent to the location slot 14, which is defined by adajcent ribs 30 (see Figure 4) the base is provided with securing means which is so constructed as to enable the relatively free insertion therein of a stem portion 20 of a marker 16, but to restrain separative movement thereof.
  • a protrusion 32 which is generally triangular in shape, and which is at rest in a position in which it extends partially across the slot 14. The protrusion 32 is moved away from the slot on insertion therein of a stem portion 20, by engagement of the stem portion with the angle face of the protrusion.
  • the rib 30 a can be caused to move in a generally clockwise direction, to move the protrusion 32 away from the slot 14.
  • Such movement is facilitated by the provision, surrounding the area 34, of a channel 36 (see Figure 1), which additionally defines the area against which pressure needs to be exterted in order to move the protrusion 32 to its release position.
  • a channel 36 see Figure 1
  • the protrusion may be withdrawn from the slot 14, and marker 16 readily removed from the base 6.
  • the frictional forces between the stem 20 and the protrusion 32 are sufficient to retain the stem in the location slot 14 against forces encountered during normal use of the assembly of base and marker, including the possibility of lifting the assembly by grasping of the upper portion of the marker, and forces such as wind and draft.
  • the force required to remove the stem against the frictional enagagement by the protrusion 32 is less than the force required to overturn the base, particularly when the base is interengaged with adjacent bases.
  • the marker be subject to an impact, such as an upward impact or an impact sideways of the length of the base, the marker will be permitted to become free of the base in preference to causing the base to be overturned.
  • a line of bases 6 may quickly and conveniently be laid down upon a roadway to delineate a hazard, such as a closed lane of a motorway, by the provision of the white line afforded by the array of edge margins 12, and this will be accentuated by the location as is necessary of markers 16 into the slots 14.
  • the shallow angle of the edge margin 12 reduces tendency of the bases to be displaced from their desired positions, and should the wheels of a vehicle ride over the edge margin and striker marker 16, the marker will be flexed about the stem portion 20, and subsequently returned to its upright position. Notwithstanding should one or more markers of an array break, this is unlikely to cause a hazardous situation, and they may be replaced relatively easily.
  • the construction in the form of generally flat bases and generally flat markers, enables a large number of traffic bollards to be transported without an undue taking up of space.
  • the edge margin 12 may have secured thereto a reflective stud 40, as is illustrated in Figure 4.
  • a reflective stud 40 is conventionally adhesively secured to the road surface in one of two orientations, presenting one of two reflective sides to the oncoming traf fic, depending as to whether or not they are provided on the off side or the near side.
  • the stud is secured by a bolt 42 to the edge margin 12 in a manner such that it may be rotated in order that an appropriate one of the two sides 40 a , 40 b is directed towards the oncoming traffic.
  • a stud with a reflective lens on only one side (40 a or 40 b ) may be so utilised, being rotatable as is necessary in accordance with the side of the road upon which the base is deployed.
  • the base has been described herein above and illustrated in the drawings as being of unitary construction, if desired the base may comprise separately-moulded outer and inner portions, the inner portion being defined by the dotted line in Figure I and being inserted into an aperture provided in the remainder of the base.
  • the central portion of the base comprising the location slot, securing means and the release means, may be moulded of a relatively hard plastics material, or plastics material which is less subject to variations in physical properties on increase in temperature, whilst the remaining outer portion of the base may be moulded of a softer plastics material.
