Description

FLEXIBLE DISPLAY PANEL FOR APPLICATION TO VEHICULAR OR PEDESTRIAN SURFACE
This invention relates to a flexible display panel or "image" for application to a vehicular or pedestrian surface (i.e. surface over which vehicles or pedestrians can or may run), such as a parking surface in a vehicle car park, or road surface, pathway, corridor, hard standing area, footpath; and also upright surfaces such as exposed faces of columns or walls.
It is of course well known to erect display panels alongside the public highway, or on buildings and also to provide free-standing display or advertising panels on or adjacent to pedestrian ways. However, the present invention addresses specific problems encountered, when seeking to provide a display or advertising image or panel for application to vehicular or pedestrian surfaces.
Evidently, if display panels are to be applied to concrete or other vehicular or pedestrian surfaces, such panels will be exposed to wind and rain, and also the adverse action of wheel-driven dust or water, de-icing salts and cleaning compounds, and point-loading of a stiletto heel, and must therefore be resistant to attack from such sources if the panels are to have any reasonable working life.
It is known to apply road markings e.g. road centre lines, car lanes and driver instructions, such as "halt" or "slow", but such markings are produced from thermoplastic materials, are applied in hot form, and require specialised equipment to apply the markings. They are also difficult to remove, and in fact removal always leaves some surface damage.
It is also known to provide pre-formed rubber segments which are mechanically or adhesively secured to road surfaces to form "traffic calming" humps, and such segments usually bear some painted markings to enhance their visibility.
The invention, however, has been developed primarily with a view to provide a flexible display panel or "image" which can be adhesively applied to a vehicular or pedestrian surface using simple pressure contact e.g. using a heavy roller, and which is sufficiently durable to resist degradation or deterioration for an acceptable time period when exposed to ambient weather conditions, and also abrasive attack from vehicle wheels and pedestrians running over the panels, and yet retain acceptable skid values.
It is envisaged that the invention will be particularly attractive to owners and operators of vehicle car parks, in that there will be a captive market of car users and pedestrians which can be exposed to advertising material by application of display panels to concrete, asphalt, timber or other vehicle parking and pedestrian surfaces.
In particular, the invention seeks to provide flexible display panels (images), which are sufficiently durable to maintain the overall integrity of the panel for a reasonable period in situ, while at the same time maintaining an acceptable visibility of the displayed information. According to the invention there is provided a flexible display panel (image) for application to a vehicular or pedestrian surface said panel being formed by a laminated assembly, which comprises. a fibrous backing layer which is capable of carrying a printed image in order to display any required visual material; a foundation layer united with the backing layer and constituted in such a way that the foundation can adhere the display panel to a concrete or other vehicular or pedestrian surface upon application of a downward pressure to the display panel; and a transparent wear and weather resistant top coating layer applied to the upper surface of the backing layer in order to protect the backing layer while rendering visible the printed material on the backing layer.
A flexible display panel according to the invention may therefore be printed with any required visual material or information on the upper surface of the fibrous backing layer, and the underlying foundation layer protects the underside of the backing layer while at the same time serving as the sole constituent of the panel, which is utihsed to adhere the panel to a concrete or other surface.
With regard to the upper surface of the backing layer, the overlying coating layer protects the backing layer from ambient weather conditions, and also renders the panel resistant to wear damage from vehicle wheels or foot traffic, but the cover layer is transparent so that the printed material remains visible.
Preferably to provide visually distinctive advertising or other material, the fibrous backing layer is capable of receiving, and holding substantially permanently, a digital or printed image.
The foundation layer is preferably a bituminous layer, in the sense that is made of, or includes bitumen, or bitumen-like material (or is adhesively based), and which will preferably be treated in such a way that, in relation to prevailing ambient temperature and conditions, the foundation layer is capable of adhering to the support surface, by diffusion or otherwise, following application of downward pressure e.g. using a heavy roller, to the upper surface of the panel. In addition, the panel should be able thereafter to be capable of remaining adhesively united to or with the support surface, while being exposed to the ambient temperatures. In other words, different pre-treatment of the bituminous or adhesive layer will take place according to the anticipated range of ambient temperatures in the intended place of use. As an alternative material for the foundation layer is any suitable adhesive material.
In some circumstances, it may be desirable to apply a primer to the support surface and/or to the underside of the foundation layer, to improve adhesion, where necessary, to the support surface.
The backing layer is preferably a woven layer of natural and/or synthetic fibres, and optionally with integration of paper compounds. The coating layer may be made of a material, which is water-resistant, and also U.N. resistant. To improve the durability of the panel, and its resistance to abrasive action from vehicle wheels the coating layer may incorporate glass beads, clear silica beads or opalescent sand. Desirably, the coating layer is provided with reflective properties plus skid resistance.
A preferred embodiment of the flexible display panel (image) according to the invention, for application to a concrete or other vehicular or pedestrian support surface, will now be described in detail, by way of example, with reference to the accompany schematic cross- sectional illustration.
Referring now to the drawing, a flexible display panel (image) according to the invention is designated generally by reference (10) and is illustrated schematically, and applied to a concrete or other vehicular or pedestrian support surface (11), which may be a parking surface or pedestrian access way in a vehicle car park, e.g. multi-storey car park, a road surface hard standing area or corridor.
The panel (10) is formed of a laminated assembly, which comprises a fibrous backing layer (12), which is capable of carrying a printed image, preferably a digital image in order to display any required visual information or material. A bituminous (or adhesive) foundation layer (13) is united with the backing layer (12) and is constituted in such a way that the foundation layer (13) can adhere the display panel (10) to the concrete or other support surface (11) upon application of downward pressure to the display panel e.g. using a heavy roller i.e. by cold rolling.
A transparent wear and weather resistant top coating layer (14) is applied to the upper surface of the backing layer (12), and also overlies and protects the printed image (15) while at the same time linking with the foundation layer (13) carried, or actually incorporated into the surface of the backing layer (12). The top coating layer (14) therefore protects the backing layer and the printed image, from both weather conditions, and also from abrasive action of vehicle wheels, or pedestrian traffic running over the display panel. The coating layer also renders the printed material on the backing layer visible, whilst at the same time integrating all component parts. The foundation layer (13) is a bituminous layer, in the sense that it is made of, or includes bitumen or bitumen derived constituents, or bitumen-like material, or adhesive compounds. Also, the constituents of the foundation layer (13) will be pre-treated in such a way that, in relation to prevailing ambient temperature and conditions, the foundation layer is capable of adhering to the support surface (11), by diffusion or otherwise, following application of downward pressure by a heavy roller. In addition, the panel (10) is capable thereafter of remaining adhesively united with the support surface (11), while being exposed to ambient temperatures.
Evidently, in colder climates, the pre-treatment of the foundation layer (13) will be different from the pre-treatment when the intended location of the use of the display panel is in an environment having a warmer climate. In some circumstances it may be desirable to apply primer to the support surface (11) and/or to the underside of the foundation layer (13) to improve the adhesion of the display panel (10) to the support surface (11). The backing layer (12) is a woven layer of natural and/or synthetic fibres, and optionally incorporating paper.
The coating layer (14) is made of material, which is water resistant, clear and U.N. resistant. To improve durabihty of the panel overall, and in particular to provide improve resistance to abrasive action from vehicle wheels, the coating layer (14) may incorporate glass beads, clear silica beads, or opalescent sand.
