Definitions

  • This invention relates to a base for supporting a temporary barrier.
  • a temporary barrier such as a fence may be provided with support posts, and a base for supporting a post may have a socket for receiving an end portion of a support post.
  • a base for supporting a post may have a socket for receiving an end portion of a support post.
  • the base may have a spigot which is received within the end part of the support post.
  • Other barriers such as panels of plastics material may be provided with a support post or spigot and the base will have a socket for receiving an end portion of that.
  • a barrier panel of plastics material may be provided with a socket to receive a spigot projecting from a base.
  • the bases may be made of concrete or of plastics material, such as recycled plastics material. Their function is to prevent unwanted displacement of the support post and to resist the temporary barrier, such as a fencing panel, being knocked or blown over. A problem with such bases is that they may present a trip hazard to pedestrians. A number of solutions have been proposed, such as colouring the base with a bright colour.
  • An object of the present invention is to provide a base which presents a significantly smaller trip hazard.
  • a base for a temporary barrier comprising (i) a support portion of plastics material on which is provided an upwardly extending spigot or socket for engaging with a part of the barrier; (ii) a first elongate, horizontally extending, ground engaging stabilising member of plastics material which is connected to and extends from the support portion to a first remote end; (iii) a first elongate stiffening member which is connected to the first stabilising member and extends horizontally from adjacent the first remote end towards the support portion; (iv) a second elongate, horizontally extending, ground engaging stabilising member of plastics material which is connected to and extends from the support portion to a second remote end in a direction opposite to the first stabilising member; and (v) a second elongate stiffening member which is connected to the second stabilising member and extends horizontally from adjacent the second remote end towards the support portion; wherein the first and second stiffening members are separate and do not define a continuous
  • each stabilising member is of low profile.
  • low profile is meant that the height of the stabilising members over major parts of their respective lengths is below a height that would provide a significant risk of tripping for a pedestrian.
  • the height of the stabilising members over major parts of their respective lengths does not exceed about 40 mm.
  • the stabilising members have lower heights than 40 mm.
  • the height of the stabilising member, above the ground on which the base is resting does not exceed about 35 mm, or about 30 mm, or about 25 mm, or about 20 mm, or about 15 mm or about 12.5 mm. In some embodiments, the preferred maximum height over the major part of the length of each stabilising members is about 25 mm.
  • each stabilising member is profiled so as to avoid abrupt edges, for example having rounded edges and a rounded end, so as to reduce further the risk of tripping.
  • the height a stabilising member above the ground on which the base is resting does not exceed a particular dimension
  • references to the length of the stabilising member from its remote end are references to the distance from the remote end of the stabilising member to the upwardly extending axis of the spigot or socket of the base.
  • the two stabilising members may be of the same longitudinal extent, or the arrangement may be asymmetrical.
  • the length of the stabilising members will depend on the application for which the base is intended, and will be chosen to prevent tipping over of the barrier with which the base is to be used.
  • the stiffening members serve to reinforce the stabilising members.
  • the stiffening members may be in the form of rods or tubes and in general will be of the same or similar profiles although they could have different profiles. Their lengths may depend on the lengths of their respective stabilising member.
  • the stiffening members may be of a suitable material to so as to be substantially rigid, or to be semi-rigid so as to have a sufficient degree of flexibility to assist in assembly of the base.
  • the respective stiffening members could be of different materials but in preferred materials they are of the same materials.
  • the members may be of a metal such as steel.
  • the members are of a fibre reinforced plastic material.
  • the members are manufactured by a pultrusion technique.
  • Such a member may comprise fibres, for example of glass or carbon, in a suitable resin such as a vinyl ester resin.
  • a suitable resin such as a vinyl ester resin.
  • Such members have been used in the reinforcement of concrete. For reasons of cost, it is preferred to use glass fibres in a resin matrix, formed by pultrusion. Generally such a stiffening member will have increased resilience as compared to metal members.
  • the stiffening members may be in the form of rods.
  • the rods may have a hollow centre, so as to be tubular.
  • the stiffening members may have any desired cross section, such as being circular, oval, square, oblong, flat, cruciform or any other desired cross section, whether solid or hollow.
  • One or each stiffening member may terminate short of the support portion. Alternatively, one or each stiffening member may extend to the support portion. In such an arrangement, one or each stiffening member may be joined to the support portion.
  • one or each stiffening member comprises a plurality of sub-members. These may abut, or be joined together, or be sufficiently closely spaced from each other, so that the sub-members of one stiffening member effectively define a continuous stiffening member.
  • the respective stiffening members may have facing ends which abut or are joined together or are sufficiently closely spaced from each other, so that the stiffening members effectively define a continuous stiffening member.
  • the invention may thus be varied so that whilst there are separate first and second stiffening members, effectively the stiffening members do define a continuous stiffening member extending from adjacent the first remote end of the first stabilising member to adjacent the second remote end of the second stabilising member.
  • the engagement of the base with a barrier may be directly, for example by means of a socket of the base receiving a spigot of the barrier panel; or a spigot of the base engaging with a socket of the barrier panel; or the engagement with the barrier may be by way of a socket of the base receiving the end of a support pole for a barrier or a fence; or a spigot of the base engaging within a hollow support pole of a barrier or fence.
  • spigots or sockets there may be a plurality of spigots or sockets on the base. This is applicable in particular where the base engages with poles of a fence since if two spigots or bores are provided the base will provide a junction between two fencing panels.
  • the or each spigot or socket may be formed by plastics material, by metal, or by a combination of materials.
  • Some embodiments of the present invention involve the use of an upwardly extending member providing a spigot for the base which engages in a hollow fencing support pole.
  • an upwardly extending member which is hollow so as to serve as a socket to receive e.g. a fence pole.
  • the or each upwardly extending member may be made of metal, such as steel.
  • the or each upwardly extending member may be in the form of a tube.
  • the free end of the or each upwardly extending member may be chamfered to facilitate insertion into a support tube for fencing or the like.
  • it could taper and this could be provided by using a plurality of upwardly extending member portions of different external diameter, joined together in series.
  • a socket is provided, this could be wider initially to assist insertion of a fence pole or the like, and will then narrow to provide a secure seating of the pole. Again this could be achieved by using a plurality of upwardly extending member portions of different external diameter, joined together in series.
  • the or each upwardly extending member has a lower end which is connected to an open ended hollow member extending in the direction of the stiffening member, into which each stiffening member passes.
  • the or each upwardly extending member then passes upwardly through an associated aperture in the support portion of the base. If there is a plurality of upwardly extending members, there may be an individual aperture for each upwardly extending member or there may be a common aperture for a plurality of upwardly extending members.
  • the lower surface of the hollow member is flat.
  • the hollow member may for example be a portion of box section.
  • the cross section of the hollow member may be rectangular, for example square. However the cross section of the hollow member may be of any other cross section, such as circular, elliptical or polygonal.
  • the hollow member may be of metal such as steel.
  • an upwardly extending member defining a spigot or socket is metal, and the hollow member is also metal, then the two may be joined together by welding.
  • An equivalent component could instead be a moulded or fabricated component of other material such as plastics. Assembly is simple in such arrangement, with the or each upwardly extending member being pushed through the aperture in the support member, and each stiffening member being pushed into position, into the hollow member. If the hollow member is of metal and the stiffening members are of metal, they could be welded to the hollow member.
  • the ends of the stabilising members may be provided with portions which restrain their respective stiffening member against longitudinal movement when the stiffening member is in position, at least one of the portions being capable of flexion so that the stiffening member can be inserted, and then returning resiliently to keep it in position.
  • the stabilising members define feet for the base and could be of an appropriate high visibility colour such as yellow or orange.
  • each stabilising member there could be a plurality of laterally spaced stiffening members, which are preferably substantially parallel to each other.
  • each stiffening member could extend from adjacent the remote end of the first stabilising member to adjacent the remote end of the second stabilising member.
  • each stabilising member could have separate stiffening members.
  • a stiffening member could extend through a bore or an open recess formed in a respective stabilising member.
  • a base in accordance with embodiments of the invention presents a reduced risk of tripping to pedestrians, because the protruding foot is of low profile, preferably has rounded edges, and is preferably brightly coloured.
  • a base as described in accordance with all of the aspects set out above, but modified to exclude the stiffening member or members.
  • stiffening member or members there may be provided:
  • a base for a temporary barrier comprising (i) a support portion of plastics material on which is provided an upwardly extending spigot or socket for engaging with a part of the barrier; (ii) first and second elongate, horizontally extending, low profile ground engaging stabilising members of plastics material connected to the support portion, the stabilising members extending in diametrically opposite directions from the support portion to respective remote ends of the stabilising members; each stabilising member being of a material which is sufficiently stiff whereby the stabilising members are not provided with a stiffening member.

  • a metallocene comprises a positively charged metal ion sandwiched between two negatively charged cyclopentadienyl anions. This is in contrast to a stabilising member which does need a stiffening member, which may be of polyethylene for example. However, it will be appreciated that such materials may be used for a stabilising member which does require a stiffening member.
  • the or each upwardly extending member has a lower end which is connected to an additional member extending in the direction of the stiffening member, such as a hollow member as described above.
  • the additional member is extended along the stabilising members by a sufficient distance so that it provides a stiffening effect itself and there is no need for additional stiffening members.
