Definitions

  • This invention relates to a marker post and more particularly but not exclusively a marker post for roads.
  • Marker posts for roads commonly known as verge markers or wayside markers are of two main types, rigid and flexible.
  • rigid posts In order to install the rigid posts they can be driven into the ground in the manner of a pile.
  • special tools are needed if the post is to be driven into the ground without breaking the post.
  • the posts themselves are not particularly expensive these special tools are relatively much more costly so that the overall cost of installation is high.
  • An alternative to the use of special tools is to dig a hole for each post and fix the post in place with concrete poured into the hole. These procedures are time consuming and labour intensive. As a consequence the overall cost of installation is also expensive.
  • the present invention has been made from a consideration of these problems.
  • a marker post comprising a flexible body portion and a rigid base portion, the flexible body portion being adapted to be flexed sufficiently to expose the top of the rigid base.
  • the body is made of flexible plastics material and the base is made of metal.
  • the plastics material and the body shape should be of the kind which, for the purpose of installation, can be bent or flexed sufficiently to expose the tip of the metal base without permanent set so that when unrestrained the body will return to its normal position. Examples of shapes which are suitable are disclosed in European Patent 0103578.
  • the metal base is preferably of profiled section for example T-shaped, U-shaped, L-shaped, of box section or other suitable cross-section.
  • the base may be unprofiled, for example of circular cross-section.
  • the metal base is fixed to the lower end of the flexible body at a location below the top of the base.
  • the top of the flexible body can be flexed away from the base to expose the top of the base which can then be driven into the ground by suitable means such as a hammer. When the flexible body is unrestrained it returns to its normal disposition.
  • the marker post comprises a body 10 preferably of flexible plastics such as a polypropylene which can be flexed without permanent set and which does not become brittle at low temperatures.
  • the body is of part circular cross section and preferably of gradually reducing lateral arcuate extent from bottom to top. In the embodiment illustrated the bottom of the body extends laterally over slightly more than a semi-circle (Fig.4) and at its top the body extends over slightly less than a semi-circle (Fig.3).
  • the lowermost part of the body is of tapered form.
  • the base 12 of the post comprises a rigid elongate member, preferably of metal.
  • the cross-section of the base in the embodiment illustrated is T-shaped.
  • Other profiles can be used for example U-section or box section.
  • L-shaped cross-section bases are not always entirely satisfactory however, as they may twist in use.
  • the base is fixed to the concave side of the body by appropriate fasteners such as bolts or rivets 14 so that the longitudinal axis of the base is substantially aligned with the centre line of the body.
  • the base is secured such that about half of its length projects below the bottom of the body.
  • the uppermost fastener is located a short distance below the top of the base.
  • a barb 16 is provided adjacent the bottom end of the base.
  • the body In use the body can be bent away from the base as illustrated in Fig.5. The base can then be driven into the ground using a simple tool such as a hammer or mallet. When the body is released it springs back to the upright position. The whole operation takes a few minutes and requires no special equipment. The barb prevents the post from being pulled out of the ground.
  • a hole may be preformed as by drilling. Provided that the hole has a diameter which is about the same as the maximum cross-sectional dimension of the base 12, insertion of the base into the hole can be accomplished quite readily and the base will be held firmly in the hole. Even if the hole is larger than the cross section of the base the barb will hold the post in place. The costs of this kind of installation do not greatly exceed the costs of installing the marker post of the invention in softer ground.
  • the invention is not restricted to the above described embodiment. Many variations and modifications can be made.
  • the post can carry some reflective material so that it will be noticeable at night when light falls onto it. Markings, whether reflective or not, can be applied to the post to give information, for example direction, distance, hazard warning, rights of way and the like.
  • the post can be used to mark the line of footpaths, bridle paths or tracks and it can be used to mark the line of buried services such as gas, water, electricity and so on.
  • body of the post being made of plastics
  • other flexible materials can be used for example glass or carbon fibre reinforced plastics and materials made from carbon fibre.
