EP2020002B1 - Stationary surface, for example a playing field, and method for providing signs on a stationary surface - Google Patents

Description

The invention relates to a playing field, according to the preamble of claim 1, as well as a method for applying designations on a stationary surface.

It is known not only to provide playing fields with marked lines, but also with other names such as advertising logos.

In the document DE-A-296 04 773 It is disclosed that by tinting or inserting inserts with advertising media, the turf of a football field is provided in different places. Such advertising media should also be provided in those areas on which the actual sport is carried out and thus are always in the field of vision of the cameras and the spectators. This measure should ensure that the advertising is given increased attention. However, a disadvantage is the disturbing effect which such advertising media can cause a spectator.

In the pamphlets WO 2004/090849 and WO 02/28541 Similarly, a method for producing large-area markings such as patterns, images, Signalisationshinweise etc. are described in a similar manner. For example, a mobile device having a multi-nozzle marking head disposed thereon is moved along the surface to be marked, and electronic control means controls the nozzles of the marking head as a function of the current position of the mobile device according to the reproducing original. As a result, markings, for example, on squares or other suitable surfaces can be attached, in particular for advertising purposes.

In the document DE-U-299 07 795 a method for providing advertising media is described in which these are accomplished by sowing different types of grass or by different Mährichtungen, or by spraying or painting. With the differently generated brightness of the lawn game operation should not be affected, but this can not be completely prevented.

In the publication DE-A-199 00 366 It is disclosed that non-visible additional image portions are provided by infrared or ultraviolet dyes that are only visible in a passive display device, such as a television set. The spectators on the bleachers should not perceive the generated additional image parts on the tennis court and the bands, since they are located in the infrared spectral range, which is not visible to the human eye. For the transmission of these image parts are by a television camera electrical or optical data lines and / or electromagnetic radio transmissions used, which are then made visible on a TV. But there are only isolated parts of the picture provided, which can be seen only in the TV even with normal recordings.

The present invention has for its object to exploit a playing field of a sports event, optimal for promotional purposes or the like, with a method for attaching the advertising pamphlets, advertising logos and advertising messages and / or design elements on the inventive playing field to be proposed.

This object is achieved by a playing field with the features of claim 1.

Further preferred embodiments of the inventive stationary surface form the subject of the dependent claims.

By virtue of the fact that, according to the invention, the entire area or the entire playing field can be provided with individual designations distributed uniformly in rows or in a specific pattern, optimum utilization of the area for the attachment of advertising etc. can be achieved.

The structure of the arrangement of the designations is in a particularly suitable variant according to the invention preferably chosen so that offers the viewer from a distance the image of a uniform surface structure, and only when viewed from close up, the advertising messages reveal.

In a specific embodiment, the individual names are arranged so that they are viewed from a greater distance, individually no longer recognizable and appear as a dot or spots in a larger scale grid, which forms, for example, an advertisement, advertising logo, advertising message or a design element.

In a further specific embodiment, the object formed by this larger scale grid can again - from a further distance viewed - no longer be individually recognizable, but in turn be part of an even larger scale grid. This effect can theoretically be repeated arbitrarily. This type of structuring allows the placement of advertising on objects, on which an advertising message is always recognizable from all possible viewing distances.

In a special embodiment, the advertising is applied with a reduced contrast level, so that for the viewer interested primarily in the event and not on advertising messages advertising appears not irritating and thus not too obtrusive. The size of the individual designations alone or in combination with the embodiment set out above can be selected so small that the name of the viewer becomes recognizable only in close-up through a camera depending on the resolution of the image transmission and the eyesight of the viewer, so that they promotional and yet not disturbing to the viewer of the occasion. Thus, in particular, at sports events in stadiums, the overall image of the stationary area (for example a football, rugby or cricket field) familiar to the spectator can be retained.

In the case of playing fields with field markings, the particular rows or labels or advertising logos advantageously have a noticeably smaller contrast intensity than the game markings. In an optimally coordinated design, irritations and thus the impression of too intrusive advertising can be reduced or completely prevented, especially for spectators who are primarily interested in the event, as well as among the actors.

The attachment of advertising pamphlets, advertising logos, advertising messages or design elements on a stationary surface in which it is a playing field is preferably carried out with a vehicle, which is not the subject of this invention and which has a marking head with one or more nozzles, which are individually controlled depending on the position of the vehicle and attach the names accordingly. The mobile vehicle is moved during printing along the surface to be printed and its current positions continuously determined by a positioning system, preferably a satellite navigation system. The control of the nozzles takes place in coordination with the current position detected by the positioning system.

The invention can be applied for a wide variety of applications, so it can act in the playing fields, for example, ice surfaces. These areas can be provided with advertising leaflets, advertising logos, advertising messages, pictures and / or with design elements. They are particularly suitable for sports events, but also for other occasions or major events, especially if this is associated with media coverage.

The invention will be explained in more detail with reference to the drawing.

Fig.1 shows a rugby playing field 1 as an embodiment of a stationary surface according to the invention for a sports event. Of course it could also be a different field, for example a football field, a race track or a target field set up on a street for a cycling race etc.

The playing field 1 is provided with game markings 2 and subdivided by these into a number of subfields 3.

According to the invention, approximately the entire surface of the playing field 1 is printed with uniformly distributed designations 5, 5 ', which are intended for advertising purposes and which may mainly be advertising logos. The subfields 3 bounded by the marked lines are preferably uniformly filled with the designations 5, 5 ', the size and the number of designations 5, 5' being adapted per subfield 3 of the subfield size.

The size and the contrast intensity of the attached advertising pamphlets, advertising logos, advertising messages and / or design elements can be selected such that the designations 5, 5 'can only be recognized by close-up photographs by a camera. The contrast strength of the game marks 2 is much stronger in the case shown than that of the attached imprints 5, 5 ', since the game marks 2 should always be clearly visible. The advertising logos, on the other hand, should not irritate the viewer in front of the screen or the player on the field.

For printing on the playing field 1, a vehicle 10 is used, which in Fig. 2 is shown simplified. The vehicle 10, which is movable on wheels 12, is equipped with a marking head 15 which has a plurality of nozzles (injection nozzles) 16. The spray nozzles 16 are each connected to a paint tank. They are arranged in one or more rows. The number of rows, seen transversely to the direction of travel, depends on whether one, two or more colors should be printed. The marking head 15 is preferably arranged vertically adjustable.

In the vehicle 10 electronic control means 18 are integrated, with which the nozzles 16 are controlled individually as a function of the current position of the vehicle according to a template to be reproduced. The vehicle 10 is moved along the surface to be printed, and its current positions are continuously determined by a positioning system 19, preferably a satellite navigation system. By means of the positioning system 19, the exact spatial coordinates of each nozzle 16 are determined. The control of the nozzles 16 takes place in coordination with the current position detected by the positioning system. The software compares the individual coordinates of the nozzles with predetermined desired coordinates of the individual pixels of the logo, and each individual nozzle 16 is opened in each case when it is in position exactly at the desired position of the georeferenced pixel.

A printing by the vehicle (10), especially in breaks of sports events could be provided for the restoration of any damaged designations.

In this way, the names, in particular advertising logos, easily rows over the entire surface or the entire field 1 attach and also renew if necessary.

It would be conceivable that, for example, the goal area or the penalty area of a playing field is not printed, so that only approximately the entire playing field would be printed.

It goes without saying that the application according to the invention can also exploit the effect of the partial color mixing or also all other optical effects, such as those of three-dimensionality.
