Abstract
A dispenser for use in protecting a surface or structure. The dispenser comprises a core 1 supported between a pair of end caps and a cylindrical roll of a plastic film 2 wound onto the core 1. One side of the film 2 has an adhesive coating afforded by a solvent-based acrylic adhesive. The plastic film 2 is formed with a plurality of spaced transversely extending rows of perforations. Two spaced resilient rollers 5, 5A extend parallel to the axis of rotation of the core 1 and enable the user to apply a resilient load to the plastic film 2 as it is being applied to the surface or structure. Also claimed is means for applying a plastic film to a vehicle window, the applying means comprising the features as described above.
Description
PROTECTING SURFACES AND FRANGIBLE STRUCTURES
Field of the Invention
This invention relates to the protection of surfaces and frangible structures.
One of the problems faced by firemen attending crash scenes involving motor vehicles is that, when attempting to gain access to the interior of a vehicle in which one or more people are trapped by cutting through part of the vehicle structure, they may cause breakage of one or more windows of the vehicle.
The breaking of a vehicle window can result in shattering of the glass, with the possibility of injuring one or more of the firemen and/or one or more of the people within the vehicle.
It is accordingly an object of the present invention to provide an effective answer to the above problem.
Summary of the Invention
According to a first aspect of the present invention there is provided a dispenser for use in protecting a surface or structure, the dispenser comprising a core supported between a pair of end caps, a cylindrical roll of a plastic film wound onto the core, one side of the film having an adhesive coating afforded by a solvent-based acrylic adhesive and the plastic film being formed with a plurality of spaced transversely extending rows of perforations, and two spaced resilient rollers that extend parallel to the axis of rotation of the core and enable the user to apply a resilient load to the plastic film as it is being applied to the surface or structure.
The plastic film is preferably low density polyethylene having a thickness within the range of from 40 to 100 microns, typically between 50 and 60 microns.
The rows of perforations are preferably spaced apart by a distance within the range of from 3 to 6 inches or 75 to 150 mm.
According to a second aspect of the present invention there is provided means for applying a plastic film to a vehicle window, the applying means comprising a cylindrical core supported between a pair of end caps, a roll of the plastic film wound onto the cylindrical core, one side of the film having an adhesive coating afforded by a solvent-based acrylic adhesive and the plastic film being formed with a plurality of spaced transversely extending rows of perforations, and two spaced resilient rollers that extend parallel to the axis of rotation of the core and enable the user to apply a resilient load to the plastic film as it is being applied to the vehicle window.
Brief Description of the Drawings
Figure 1 is a schematic sectional side view showing the application of a plastic film to a vehicle window, Figure 2 is a perspective view of a dispenser, and Figure 3 shows part of a sheet of protective plastic film.
Description of the Preferred Embodiment
The dispenser shown in Figures 1 and 2 comprises a pair of end caps 6 and 7 between which a core I is rotatably mounted with a roll of low density polyethylene film 2 wound onto the core 1.
The polyethylene film has an average thickness of the order of 55 microns, a longitudinal tensile strength in excess of 1 daN/cm and a transverse tensile strength in excess of 0.7 daN/cm.
The polyethylene film 2 is a clear film which is coated on one side with a solvent-based acrylic adhesive so that, as the film is withdrawn from the roll, it can be placed on a surface that requires protection and will remain in contact with that surface. The adhesion to steel is of the order of 330 cN/cm.
A pair of resilient rollers 5 and 5A, in the form of cylinders of foamed plastic material supported on central rods, extend between the end caps 6 and 7. The resilient rollers 5 and 5A are spaced from the surface of the polyethylene film 2 wound onto the core 1 and are used to assist in placing the film 2 in the required position and urging it resiliently into contact with the surface to be protected. The film 2 is highly static and this ensures that the non-adhesive side of the film 2 sticks to the rollers 5 and 5A.
The polyethylene film 2 is formed with transversely extending rows 8 of perforations and, when a sufficient length of the polyethylene film 2 has been withdrawn from the roll, the film 2 is ruptured by tearing along a selected row 8 of perforations. The provision of the resilient rollers 5 and 5A facilitates tearing. The rows 8 of perforations extend fully across the film and are typically uniformly spaced apart by a distance of the order of 100 mms. The spacing may alternatively be 50 mms, but could be as much as mms. This close spacing of the rows of perforations makes tearing easier enabling an accurate tear to be made without the need for a separate cutting tool and avoiding wastage of the film 2.
Figure 1 shows the application of a strip of film 2 to a window or windscreen 3 of a vehicle having a solid frame 4 so as to cover the frangible part of the vehicle. A number of strips of film will normally be applied, starting from a position either above or below the window. The whole of the window or windscreen will be covered with a degree of overlap onto the vehicle frame 4. The film 2 adheres securely to the surfaces to which it is applied. This ensures that, if the window or windscreen 3 should break as a result of an attempt being made to obtain access to the interior of the vehicle, the broken glass will remain adhered to the plastic film 2 and will not injure the firemen or the people within the vehicle.
The technical data for the film may be as follows:-Film Type Low Density Polyethylene, Average Thickness 55 Microns, Colour Clear with Red Print, Adhesive Type Acrylic Solvent based, Adhesion to Steel 330 cNlcm., Longitudinal Tensile Strength >1 daN/cm., Transverse Tensile Strength >0.7 daN/cm.
Although specific reference has been made above to the application of the adhesive-coated film to a vehicle window or windscreen, it is to be appreciated that the invention is applicable to the protection of surfaces and structures generally.
