Definitions

  • the invention relates to security barriers, particularly those adopting flexible cord materials such as webbing, tape, rope, cable etc.
  • the invention relates to movable barriers having said cordon members attached thereto for deployment of the cord to strain off a specific zone.
  • demarcation barriers such as to prevent the public venturing into such zones for security, safety or logistical purposes. Further, in many obvious instances, it is not necessary to have physical barriers preventing access but merely to indicate that the zone has been demarcated from general traffic. Further still, said zones may vary in position or shape or may be temporary, and so leading to the need to conveniently establish such demarcated zones and then remove said barriers as necessary.
  • the invention provides a security barrier unit comprising a housing having wheels mounted adjacent a base of said housing; a stabilising portion mounted adjacent to said base; a plurality of cassettes, said cassettes having selectively extendable cord, wherein; said cassettes are mounted to substantially vertical surfaces of said housing.
  • the invention provides a cassette for storing and retracting cord comprising a casing; a spool of cord engaged with and wound around a mandrel within said casing; said mandrel rotationally biased to retract the cord; a first directional member for engaging the cord so as to change direction from tangential with the spool to a second directional member; the second directional member for engaging the cord so as to change direction from the first directional member to a direction out of a plane defined by the spool.
  • the cassette provides a profiled inner mandrel about which the spring is coiled, said mandrel having a large diameter ratio and dual purpose profile. This may have the advantage of reducing the rotational spring tension necessary to coil the spring about it's outer circumference and also provides a slide in engagement for the inner springs 1 D' shaped location point which is difficult under normal circumstances to ensure it stays engaged.
  • said housing comprises at least one surface inclined to the vertical plane.
  • said at least one inclined surface progressively projects away from a central vertical axis of said housing as said surface approaches said base.
  • said housing includes an upper surface inclined to the horizontal plane. Similar to the embodiment incorporating vertically inclined surfaces, a horizontal surface inclined to the horizontal plane, such as about 5 degrees, may also provide a downward force component on application of a wind load.
  • said stabilising portion including a weight located adjacent to a base of said housing.
  • said stabilising portion including a selectively engage-able weight, such as the addition of water or sand. Such a stabilising portion may permit the addition of 5, 10 or 20 kilogram subject to the desired application and available volume of said portion to receive sand and/or water.
  • said unit may include a tow bar for attachment to a vehicle.
  • said wheels may be adapted for vehicular speeds and so making said unit more applicable to vehicular deployment.
  • the cord may be equally be applicable to the use of webbing, rope, cable or other flexible elongate materials that permit repeated cycles of winding and unwinding from a relatively small diameter spool.

  • FIGS IA to IE show one embodiment of the security barrier housing 1, according to the present invention.
  • the security barrier housing 1 is a selectively mobile device having handles 20 which may be used to tip the housing 1 above the wheel 10 so that the housing 1 may be transported to the desired location
  • the housing 1 includes cassettes 5 which are supported within the vertical sides 75 A, B, C of the housing, hi this embodiment, there are up to six cassettes mounted within the vertical faces of the housing. Further, in this embodiment, the cassettes 5 are removable so that they can be used either separately from the housing or whilst mounted within the housing. Each cassette has an orifice 55 from which a cordon material may be extended. Said cordon material may be mounted to a fixed support (not shown) or for use with multiple housings 1 may be engaged with purposed built engagement portions 50 so that the housings 1 can be used in a free standing form.
  • the housings may be manufactured from a polymer material such as polypropylene, MDPE, HDPE or other plastic material suitable for use both inside or outside. To this end, the housing may be manufactured from materials dedicated to the purpose for indoor use or external use or as previously mentioned, from material that is equally applicable both indoors and outdoors.
  • the housing has an upper surface 80 having drain hole 15 so that accumulated rain will drain easily and so further applicability to outside use.
  • the base includes drain hole 25 for any rain that accumulates within the housing 1.
  • the housing 1 includes useful spaces within the housing 27, 28.
  • 1 27 is open with a enclosed space 28 having a door 40 pivotably open through hinges 45.
  • the door 40 may be opened using a handle and further may include an undercut lock 70 for securing the door 40 in placed.
  • the housing 1 may also be useful for securely storing fire extinguishers, tools, flash lights or other safety equipment, for outdoor use, or brochures, stationery or personal effects for inside use.
  • a stabilizing portion 30 which is used to secure the housing 40 in place, particularly for use outside where wind loads may topple the housing, which is a notable flaw of systems of the prior art.
  • a stabilizing portion 30 is conveniently put into a storage area whereby water sand or other particular matter may be poured within the unit 30 through office 35.
  • the stabilizing portion 30 may also be pivotably mounted within the housing 1 for ease of removal of the material.
  • the housing may be moved to the desired area and only then be weighted down by the addition of material into the stabilizing portion 30 and so avoid the problems of prior systems that must be manhandled with stabilizing weights already and fixably mounted to the device.
  • the housing 1 is further adapted in this embodiment to resist wind blots when used outside.
  • inclined faces 75A, B, C shaped in a frusto-conical shape when viewed inclined wind bearing on the housing 1 will forcibly be directed around the housing 1 due to the frusto-conical shape of the housing.
  • the inclined faces 75 A, B, C direct a component of the wind load downwards assisting in the stability of the housing.
  • the upper surface 80 is inclined 60 to the horizontal plane. In this embodiment, the inclination is about 3 degrees which may be sufficient to further add to the stabilizing effect by directing a component of the wind blot downwards and further provides a surface which may be sufficiently flat to retain objects placed on top of the housing 1.
  • a ridge around the top surface 80 is also provided such that should an object be placed on the surface 80, it will be retained by the ridge without falling from the inclined surface.
  • the upper surface 80 may be used for retaining objects.
  • Said surface may also be used as a writing surface which may be valuable for outside use, such as for personnel on an airport tarmac where a writing surface may be lacking or alternatively, in an indoor use, for instance, during an exhibition whereby exhibitors may used the housing 1 to secure areas within the exhibition hall, and further be able to use the top surface for writing of orders, etc.
  • a further aspect of the housing 1 is the addition of a tow bar (not shown) which may be mounted adjacent to the handles 20.
  • the tow bar may be attached to the back of a vehicle for transportation by the vehicle.
  • the wheel pin will be selected for vehicular use and in any event, further increases the flexibility of the housing 1 for easy deployment such as around an airport tarmac or transportation outside between distant locations.
  • the invention may provide a highly visible and rapidly deployed, aerodynamically designed queue management barrier system.
  • the housing of said security barrier unit may be shaped to take advantage of high or low pressure air flowing over the sculptured outer elevations, which may lead to a venturi suction effect.
  • Figure 2 shows an exploded view of one cassette 5 which is adapted to be mounted to the housing 1.
  • the cassette is assembled within a casing 85, which comprises an outer casing
  • the casing 85 is tear drop shaped, having an enlarged area, into which a spool of webbing (not shown) is wound about a mandrel 100, and a smaller area into which is mounted the feeder assembly.
  • the mandrel is assembled from a core 105 which is fixed to a pin 107, with the pin 107 mounted to one part of the casing 95.
  • the core 105 is located within a two part mandrel drum 110, 115.
  • a rotational spring (not shown) which provides a retracting force to the webbing such that on release of the extended webbing, the spring applies a force to retract the webbing back within the cassette 5.
  • a first roller 120 rotating about an axle 125, receives the webbing from the spool and directs from a tangential direction to a second roller 130, rotating about a second axle 135.
  • the second roller 130 then directs it to an exit member 140.
  • the exit member 140 includes a rod 145 which is inclined to the plane defined by the casing 95. The rod receives the webbing from the second roller 130 turning the webbing and directing it out of plane from the spool and subsequently through an orifice 150 in the outer casing 90.
  • the feeder assembly comprising the first and second rollers and the exit member cumulatively change the direction of the webbing so as to direct it out of plane from the spool.
  • Mounted to the webbing may also be the return bracket 155 which prevents the webbing from fully retracting into the casing 85, and a mounting clip 160 to facilitate the mounting of the webbing to a stationary device or other housing 1.
  • FIG 3 shows the cassette 5 with the outer casing removed.
  • the webbing 165 is shown mounted to the mandrel (not shown), and placed within the inner casing members.
  • the leading end 166 of the webbing is yet to have the mounting clip attached.
  • Figure 4 shows the cassette with a part of the inner casing 87 removed, so that the feeder assembly can be seen.
  • the feeder assembly comprises a first roller 120 which receives the webbing directly of the spool 165, and directs it to a second roller 130.
  • the rollers may be straight rollers.
  • tapered rollers may be used to further assist in preventing jamming of the webbing on retraction.
  • the webbing is then directed to the exit member which has been removed for clarity.
  • Figure 5 shows the mandrel 100 with the cover removed showing the rotational spring 175 mounted between the core 105 at mounting point 180 and the drum 115.
  • rotation of the drum through retraction of the webbing primes the spring against the non-rotating core 105 sufficiently to retract the webbing back within the cassette.
  • nylon bearings may be used to facilitate wear resistant rotation of the mandrel.
  • the exit member 140 comprises an inclined rod 145 mounted to the inner casing 95. The rod 145 is arranged so as to receive the webbing and gradually "turn” it so as to direct the webbing out of the plane of the spool.
  • the exit member incorporates a fixed rod of a material selected to withstand the significant wear associated with repeated use extension and retraction of the webbing, without adding significantly to frictionally resistance.
  • the surface of the rod may be hardened steel surface.
  • the surface may include a low friction wear resistance surface such as Teflon or a ceramic material.
  • the rod may be replaced by a roller.
  • FIG. 7 shows a further overview of the spool 165 mounted to the mandrel 100.
  • the webbing is then directed through the feeder assembly, and eventual exiting of the cassette (not shown).
  • FIGS 8 A to D show a wall mounted bracket 195 for mounting a leading end of the webbing to a fixed object.
  • the wall mounted bracket 195 comprises two parts 200, 220, one part 200 arranged to be affixed to a wall (not shown) which provides a pivotal point for the slotted fascia panel 220.
  • the fascia panel 220 is held in its pivotal position by a spring loaded pin 205, 210, 215.
  • the fascia panel 220 is intended to flap up and down such that, when not in use, gravity and a magnet (not shown) hold the two components 200, 220 together to ensure as close an engagement as possible against the wall.
  • a buckle not shown
  • said engagement automatically causes the panel 220 to tilt outward from the bottom to enable a correctly angle engagement of the buckle.
  • FIGS 9, 1OA and 1OB show an alternative arrangement to the use of a first roller.
  • a speed limiter 230 is placed in line with the webbing 187 leading from the spool 165.
  • the speed limiter 230 comprises a pair of conventional rollers 235, 250.
  • Intermediate the two rollers 235, 250 is located a rotational member 240 having an offset axle 245 about which the rotational member is free to rotate within the range limited by contact with the two rollers 235, 250. Accordingly, the rotational member oscillates between the limits of the two rollers 235, 250 subject to whether the webbing is being extended or retracted.
  • Figure 1OA shows the position of the rotational member 240 when the webbing is extended 257. If the speed of extension of the webbing exceeds the desired amount, friction will rotate 258 the rotational member about the offset axle, jamming 260 the webbing 255 against the respective roller 235 and so preventing further extension until released. Similarly, as shown in Figure 1OB, on retraction the rotational member 240 is rotated 267 until it jams 270 the webbing 265 against the opposing roller 250.
  • the degree of speed limitation may be controlled by biasing the axle 245 of the rotational member with a spring (not shown), such that the member 240 is only rotated once a pre-determined speed is reached; the stiffer the spring the higher the speed of the webbing before the speed limiter is engaged.
