DESCRIPTION

Anamorphic advertising device for sports fields

The present invention refers to an anamorphic advertising device for sports fields that is especially applicable to outdoor sports fields, such as soccer fields, although the invention is not necessarily limited to said application.

Anamorphic advertising devices for sports fields are known. Anamorphism is a technique that deforms an image or advertising motif to create in the viewer a false appearance that you are seeing the advertising motive from a certain point of view. Said anamorphic arrangements are used so that the observer of an event from a selected point of view has the impression of observing an advertising device, arranged high relative to the horizontal plane, when in fact he is observing an anamortically deformed device located horizontally at ground level . This allows to place apparently non-horizontal devices, but that do not interfere with the trajectories of the athletes. An example of such horizontal flat devices can be seen in Spanish Patent Document ES2152182.

Said advertising devices are made on a substrate that has a deformed advertising logo on its upper surface. Usually, the substrate is plastic or cardboard and the advertising logo is placed on the upper surface painted or applied by a self-adhesive vinyl film or glued to it. It is common for the shape of such devices to be trapezoidal, although the latter is not necessary.

A disadvantage of such anamorphic devices is their behavior when the atmospheric conditions are not favorable. In particular, if it rains or the sunstroke is very strong the device shines, which is undesirable since it alters the advertising image to be transmitted. On the other hand, if there is a very strong wind, the wind can lift the device and move it. A solution to this last problem would be to make the device heavier, but then it is difficult to install and uninstall the device on the field floor.

It is an objective of the present invention to disclose an anamorphic advertising device that provides a solution to the aforementioned problems.

More particularly, the present invention discloses an anamorphic advertising device comprising a flat substrate on which a deformed advertising logo is printed, characterized in that the substrate is a flexible substrate that is composed of a first felt layer in which it remains printed said logo, said felt layer adhered to a lower layer of synthetic material, and because the layer of synthetic material is rubber or a material comprising it.

The substrate of the device object of the present invention is more resistant to wind because its flexibility contributes to a better adaptation to the ground and due to the non-slip properties of rubber. In addition, the felt, which is printable, has some ability to absorb water that is sent to lower layers of the layer and does not result in glare caused by the sun or by the accumulation of water on its surface.

Preferably, the lower layer of synthetic material has a weight per unit area greater than that of the felt layer. When this happens, the lower layer has a greater weight than the upper layer. In this way the stability on the ground of the device against wind blows is reinforced.

In a particularly preferred embodiment, the device has through holes distributed along its surface for water drainage. These holes, which can be small in size so as not to be noticed from a distant position, allow the drainage of rainwater absorbed by the felt layer. The holes can also be used to pass joists for fixing on the sports floor.

Preferably, the lower layer has on its lower face, intended to contact the ground, a repetitive relief drawing to improve friction with the ground. This reinforces the device against the effects of the wind while reducing the total weight of the advertising device, which facilitates its installation and uninstallation.

Preferred embodiments of the material comprising rubber of the lower layer may be latex or simply rubber. Rubber is especially preferred, since it is its properties that are sought.

As for the felt layer, to favor printing, it will comprise cellulosic fibers (such as paper fibers, or fibers that combine cellulose with materials

synthetic) Also preferably, the felt may initially be white, to favor the printing process.

As for the thickness of the substrate, it is advantageous if it is as thin as possible, but an excessively low weight may not be desired if strong winds are expected. Therefore, it is preferable that the thickness of the substrate is less than 5 mm. It is also preferable that the thickness of the substrate is greater than 2 mm. More preferably, the thickness of the substrate is between 2.5 and 3.5 mm.

The device object of the present invention, thanks to its flexibility, small thickness and greater specific weight of its lower layer is very tight to the ground, making it more difficult for a player or referee to stumble. In addition, the material of the top layer is non-abrasive for skin friction. The object of the present invention does not require any blunt or sharp fixing element thanks to its self-supporting quality by poise. In addition, its flexibility allows, where appropriate, the support to wrinkle or fold, damping a player's shock by sliding on the ground.

The present invention also discloses a method for obtaining an anamorphic device according to any one of claims 1 to 10, characterized in that it comprises the phases of:

- Calculation of the deformation of the logo from the measurements of the field in which the device is to be placed and the location of the television camera from which the image is transmitted, obtaining a deformed logo

- Provision of a substrate composed of an upper layer of felt and a lower layer of rubber or a material comprising it, both layers being adhered

- Printing, preferably on an inkjet printer, of the deformed logo on the substrate felt layer

This procedure takes advantage of the advantageous properties of the material selected for the manufacture of the device without the need for specialized machinery.

Preferably, the substrate felt is white before printing.

Also preferably, the shape of the advertising device is also calculated from the aforementioned measures taken, the substrate being cut according to said measurements, said cut being made before or after the printing process.

In a particularly preferred embodiment, the process comprises a cutting or punching phase of through holes distributed along the surface of the substrate

Figures 1 to 4 show a first embodiment of an anamorphic advertising device according to the present invention.

The anamorphic advertising device -1- object of the present invention is composed of a flat substrate composed of a lower layer -14-, intended to come into contact with the floor of a sports field -100-, of a material comprising rubber, such as rubber, and a top layer -12- made of felt. Both layers are joined together by an intermediate adhesive -13- that joins them.

Due to the materials and the thickness used (less than 5 mm, for example 3 mm), the substrate is flexible and can be easily adapted to the ground.

On the upper face of the upper layer -12- there is a deformed advertising logo -11-.

The device of the example has a trapezoidal shape, as seen in Figure 3.

In the example shown, the device has a series of through holes -19- that run its thickness through both layers of the substrate for rainwater drainage. The holes are distributed along the surface of the device.

In Figure 4 it can be seen that the ink of the printing process has penetrated the felt -12-, forming a tinted sublayer -121- that can be distinguished from the rest of the layer that retains its original color (preferably white)

The bottom layer may have an embossed pattern to reduce its weight, facilitate the flexibility of the device and improve the grip of the device to the ground. In the figures the drawing has not been represented.

A possible method of manufacturing the device is as follows and is illustrated with the aid of Figure 5.

First, provision is made of -500- of the substrate used for the realization of the advertising device, that is, of the material composed of two layers, one lower and one upper glued together, as explained above. Preferably, the

5

felt will be white to facilitate printing on the felt. The material can take the form of plates or roll form.

In parallel, the measures -501- of the field in which the advertising device is to be placed are taken, the coordinates of the reference chamber from which the anamorphic device is to be captured (that is, the point from which the device will appear not be deformed) This step is not necessary if such measures are already available.

Subsequently, the deformation -502- is calculated from the measurements made and applied to the logo to be displayed.

Subsequently, printing -503- is carried out on the felt of the deformed logo. Thanks to the use of the substrate of the present invention, printing can preferably be carried out by means of the inkjet printing technique, using standard type printers.

Since in a general case the dimensions of the plate or roll will not match the shape of the outline of the advertising device, the substrate should be cut -504 conveniently. This can be done before or after printing, depending on the convenience of the moment. In the event that any of the dimensions of the advertising design exceeds the size of the plate or roll, it is possible to join together several pieces of substrate. This can be done, for example, using adhesive tape on the underside of the "bottom layer" device. To reinforce the joint, the tape can be ironed after application.

It also proceeds with, where appropriate, the realization of the drainage holes. Preferably, the holes will be made once the substrate is printed, and preferably distributed evenly.

Figures 6 and 7 schematically show the principles of anamorphic transformation. In the figures it can be seen how the shape depends on the virtual size that the advertising device is to be provided when viewed from the selected point of view, which corresponds to the camera -300-. Consequently, it is necessary to have knowledge of the coordinates of the point of view and the measurements of the field, and especially of the area -101- enabled for the placement of the advertising device.

The calculation of the deformation can be done by different equivalent paths that lead to the same result. All are based - or are deductible - from the use of the technique of reverse perspective and applying knowledge of geometry and projection. Figure 7 illustrates the principle applied to an anamorphic advertising device -1- which is intended to appear to be in an elevated position from the point of view of the camera -300-. The ABCD rectangle corresponds to the situation and apparent size that you want to give to the advertising device. The A’B’CD square corresponds to the -1-real anamorphic advertising device that gives that result. As can be seen, the real anamorphic advertising device -1- corresponds to the projection on the floor plan of the sports field -100- of lines defined by the camera's point of view and the virtual image points (ABCD rectangle) that you want to get. As a result of this transformation, the advertising logo to be transmitted, which should appear to be not distorted in the view from the camera -300-, appears deformed in the anamorphic advertising device -1-. A conical perspective projection (a single vanishing point) has been used in the figure. Other transformations using other types of perspective are also possible.

Figure 8 shows an example of application to the deformation logo. The known processes focus on the calculation of parameters such as the height of the deformed logo and the angles a and b. This presents two problems. First, the use of angles leads to greater errors. Secondly, performing said graphic transformation with said parameters makes it difficult to use image processing packages. To solve said problem, the present invention provides for obtaining the two-dimensional coordinates, preferably relative (X22, and 22), (X23, y23 ') (X24, y24') (X21 'and 21') of the edges -22- , -23'-, -24'- and -21'- of the polygon in which the logo is inscribed. These two-dimensional coordinates are taken relative to the coordinates (x22, y22), (x23, y23) (x24, y24) (x21, y21) of the edges of the undeformed logo -22-, -23-, -24-, -twenty-one-. As in the figure, the transformation is easier to match the position of a point of the undeformed logo with the equivalent point of the deformed logo. If these coordinates are calculated from the geometric relationships, for example, in Figure 7, the transformation can easily be carried out by commercial image processing packages, for example, by dragging the edges of the logo from its initial position to its coordinate calculated

The manufacturing process is also applicable to other substrates other than the invention. In particular, the deformation calculation processes shown and applied to the deformation logo can be applied autonomously and independently to others.

anamorphic advertising devices made using other substrates and other manufacturing processes.
