Definitions
- the present invention relates to flexible sheeting.
- Flexible sheeting is used for many applications, for example covering a car, motorcycle, boat or other vehicle when not in use.
- flexible sheeting is often used to protect goods carried by commercial vehicles.
- Such vehicles typically comprise a tractor unit and a trailer (cargo area) connected via an articulated connection, the trailer being detachable from the tractor unit.
- Other smaller vehicles comprise a cab and a cargo area provided as a single unit.
- the term 'trailer' will be used hereinafter to refer to the cargo area of an articulated vehicle or a vehicle comprising a single unit.
- Flexible sheeting may be used to cover goods carried by a 'flatbed' trailer, or maybe used to cover goods carried by a an open-topped trailer.
- flexible sheeting is provided along sides of the trailer, the rear and roof of the trailer typically being rigid.
- the sheeting is drawn to one end of the trailer to allow easy access along the length of the trailer. Once the trailer has been loaded the sheeting is extended to close the entire side of the trailer and is secured in place using spaced apart buckles.
- a variation of the curtain- sider trailer is known as the Euro-liner. In the Euro-liner trailer posts and planks are located behind the sheeting thereby providing the sheeting with some rigidity which may help to retain goods which move during transit.
- the tilt-top is provided with panels around its edge, the panels extending part way up the vertical height of the trailer.
- the panels are arranged to tilt downwards.
- Flexible sheeting extends from the top of the trailer and overlaps the panels, thereby enclosing the trailer.
- the sheeting is pulled to one end of the trailer and the panels are hinged downwards to allow easy access to the trailer.
- the panels are secured in the upright position and the sheeting is extended along the trailer thereby closing the side of the trailer.
- the sheeting is secured in place using a system of eye holes and rings together with a TIR cord.
- a disadvantage of known flexible sheeting is that it is easily cut. Cutting the sheeting allows access to whatever is being covered or protected by the sheeting. In the case of a commercial vehicle this allows an unauthorised person to access the vehicle trailer and to steal cargo or to stow away in the trailer. In recent years it has become common for immigrants to be smuggled illegally across borders. Many people attempt to move illegally from France to the United Kingdom, and they often attempt to do this by stowing away in a vehicle trailer. The problem of illegal immigrants has become very significant within the last few years, and French and British customs authorities have introduced various measures which attempt to stem the flow of illegal immigrants. These measures include the use of carbon dioxide detectors, x-raying machines, and the introduction of a substantial fine for any haulier whose vehicle is found to contain illegal immigrants (the fine is proportional to the number of immigrants found in the vehicle).
- One attempt to make it more difficult to access a vehicle trailer comprises a chain mail curtain provided behind the flexible sheeting of a curtain-sider vehicle. This suffers from the disadvantage that the chain mail is heavy and is therefore difficult to move when the side of the vehicle trailer is to be open or closed. Furthermore, since the chain mail is separate to the flexible sheeting itself, the chain mail does not prevent damage to the sheeting.
- flexible sheeting comprising a plastics sheet bonded to a flexible sheet constructed using carbon based fibres.
- the term 'flexible' is intended to mean that the sheet is sufficiently flexible to be used as a deformable cover, for example as a side of a curtain-sider trailer.
- the carbon based fibres are synthetic aromatic polyamide fibres.
- the fibres are formed from poly (p-phenylene terephthalamide) .
- the flexible sheet is formed from Kevlar.
- Kevlar is intended to include derivatives thereof.
- the carbon based fibres are polyesters.
- the polyesters are polyethyleneterephthatate.
- the flexible sheet is formed from Mylar or Decron.
- the flexible sheet material is bonded to the plastics material by double-sided adhesive tape.
- the sheeting is suitably dimensioned to cover part or all of a cargo area of a vehicle.
- the invention also provides a vehicle trailer comprising a frame and one or more rigid walls, the trailer being provided with flexible sheeting to cover part or all of one or more walls or a roof of the trailer, wherein the flexible sheeting comprises a plastics sheet bonded to a flexible sheet constructed using carbon based fibres.
- vehicle trailer is intended to mean the cargo area of any goods vehicle, and is not limited to the cargo area of an articulated vehicle.
- the carbon based fibres are synthetic aromatic polyamide fibres.
- at least some of the fibres are formed from poly (p-phenylene terephthalamide) .
- the flexible sheet is formed from Kevlar.
- the carbon based fibres are polyesters.
- the polyesters are polyethyleneterephthatate.
- the flexible sheet is formed from Mylar or Decron.
- the flexible sheet material is bonded to the plastics sheet by double-sided adhesive tape.
- Figure 1 shows schematically flexible sheeting which embodies the invention.
- a conventional plastics sheet 1 is bonded to a Kevlar sheet 2.
- part of the plastics sheet has been removed from figure 1, so that the Kevlar sheet 2 is visible.
- Kevlar is a proprietary trademark owned by E.I. du Pont de Nemours and Company.
- the Kevlar sheet 2 is constructed using Kevlar fibres (the term Kevlar is intended to include derivatives thereof).
- Kevlar has the chemical name poly (p- phenylene terephthalamide), and has the following repeating structure:
- the length of Kevlar fibres used to construct the sheet 2 affects the flexibility of the sheet.
- the Kevlar fibres are sufficiently short that the Kevlar sheet has a flexibility comparable to the flexibility of the plastics sheet.
- the Kevlar sheet is sufficiently flexible that the flexible sheeting formed by bonding the Kevlar sheet to the plastics sheet may be used as a deformable cover, for example as a side of a curtain-sider trailer.
- Kevlar sheet is produced by Carr Reinforcements Unit la Heap Riding Business Park, Ford Street, Chester Gate, Stockport, Cheshire, SK3 OBT (product code Rl 12-003, RA115-1200PI Aramide 115Q, fabric reference KPQ601-KPA6076).
- the plastics sheet is bonded to the Kevlar sheeting using adhesive double- sided tape 3.
- the adhesive double sided tape 3 is manufactured by Kenyon Group Limited of Regent House, Regent Street, Oldham, OL1 3TZ (product code Duplicoll 1232).
- the adhesive double-sided tape 3 comprises a silk mesh netting and brown silicon paper covered with a dispersion acrylic.
- the tape is typically 0.13mm thick, and is supplied in rolls of 6mm width or 12mm width (either may be used). In the illustrated embodiment of the invention the tape is applied diagonally across the sheeting. It will be appreciated that any suitable arrangement of the tape may be used.
- the sheeting shown in figure 1 may be used for any suitable application. Since the kevlar sheet has a flexibility which is comparable to the flexibility of the plastics sheet, the sheeting shown in figure 1 may be used in the same way as a conventional plastics sheet.
- the sheeting may be used as a curtain for a curtain-sider trailer, a Euro-liner or a 'tilt-top' trailer. Where this is done, the sheeting is fitted to the trailer in the same manner as conventional sheeting.
- the sheeting may be used to cover goods on a flat bed truck, to cover a quarry-type truck, to cover any truck with a retractable roof, or to cover a car, motorcycle, boat or other stationery vehicle.
- the Kevlar sheet is extremely strong, thereby preventing cutting of the sheeting.
- the Kevlar sheet is light, and so allows the sheeting to be moved easily, for example to open or close a curtain of a curtain-side vehicle, or to locate a sheeting cover over a stationary vehicle.
- the Kevlar sheet is flame proof.
- Kevlar sheet constructed using other suitable carbon based fibres may be used instead of the Kevlar sheet.
- any suitable synthetic aromatic polyamides, or suitable polyesters such as polyethyleneterephthatate, may be used.
- suitable materials based upon polyethyleneterephthatate include Mylar and Decron. Mylar and Decron are proprietary trademarks owned by E.I. du Pont de Nemours and Company.
