DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to the handling and support of flexible material, and has particular application to the erection and handling of barricades or fences using such material. The invention is particularly applicable to barricades, and will be described herein in connection with that application.
BACKGROUND ART
Conventionally, barricades of flexible sheet material, such as brattice cloth or other open plastics fabric, is supported by so-called star posts driven in to the ground or roadway. Such posts are difficult to handle and to remove, and cause considerable damage upon removal, particularly where they have been driven in to asphalt or other roadway surfacing.
DISCLOSURE OF INVENTION
The present invention seeks to provide an approach to barricade construction which avoids these disadvantages. In particular, the invention provides a system of supporting and handling flexible material including a roll of flexible material, means attached to said flexible material for stiffening the flexible material, said stiffening means being placed at regular intervals along the length of said flexible material and means attached to said stiffening means for supporting the flexible material in use.

FIG. 25 shows various components for extending the height of the basic barricading embodying the invention.
To facilitate description of the features of the invention, reference will now be made to the accompanying drawings, in which embodiments of the invention are illustrated, and many of its preferred features shown.
MODES FOR CARRYING OUT THE INVENTION
FIG. 1 shows a length of barricading 20, in the form of open, non-woven mesh, of the kind well known for use in the erection of barricades. Fixed at intervals along the length of the material 20 are post-guiding tubes 21, of any suitable material, preferably of plastics material such as PVC, the length of each tube 21 being slightly greater than the width of the sheet 20. The tubes 21 may be attached to the sheet 20 by any suitable means, such as by ties 22.
At each end of each tube 21 there is fixed a pair of rings 23, which may also be of PVC.
In the embodiment illustrated in FIG. 1, the sheet 20 is housed as a roll within a cylindrical dispenser 24 provided with a central axle 25 and a winding handle 26.
For use with the equipment thus far described are posts 27, preferably of steel, these post being cylindrical and having a pointed bottom end and a head 28 at their upper end. The diameter of the posts 27 is such as to provide a clearance fit within the tubes 21, and the head 28 is dimensioned to abutt the uppermost of the rings 23 when the post is inserted into a tube 21.
The components thus far described may be used for the erection of barricading by placing the dispenser 24 at one end of the desired line of the barricade, drawing the sheet 20 from the dispenser to the desired length, inserting posts 27 into the successive tubes 21, and driving the posts 27 into the ground, the post being driven until the head 28 engages the top of the tube, driving the bottom of the tube against the ground. Where a significant length of barricade is to be erected, the procedure will normally be to fix the first post and then to move the dispenser 24 while paying out sheet 20.
Where the barricading is to be placed on a roadway or other prepared surface
