Graphic water display by digital control.

The present invention presents a graphic water screen generated by controlled fragmentation of the jets that compose it, generating while a water screen falls from a certain height in which texts, figures and patterns created by water fragments can be read and the empty spaces between them. The control of the actuation of the quick response solenoid valves that act on the water pumps is carried out by means of specific software and by electronically controlled electronic devices.

This innovation belongs to the field of interior and exterior architecture, as a new form of advertising screen and as an interactive multimedia projection screen. Background of the invention

The use of programmable logic controllers has allowed, since joining the industry in the early 1980s, that the response speed to activate and deactivate electrical devices (valves, lights, etc.) has been faster and faster. The first antecedent of a graphic screen that generates images by intermittently activating and deactivating a controlled group of water dispensers is S.H. Pevnick, who in his American patent 4,292,406 of the year 1981, describes how to form graphs controlled with drops of water in free fall. Subsequently, Pevnick has extended this patent by incorporating technical improvements, while maintaining the principle of operation of the first patent. The present invention differs from Pevnick's patent in that a pressurized water system is used for the projection of water jets, while the American patent is based on the principle of gravity free fall.

The gravity free fall system, although it has the advantage that the initial speed is somewhat reduced, on the contrary it requires an apparatus or water tank on the top, with a constant water level and that the valves are inside the water, with the difficulties this implies for maintenance. The system that we present through a pipe with pressurized water from which the valves are fed is much simpler, lightweight, versatile, easy to install and simple to maintain, as will be described later. Description of the invention

The present invention aims to create a water curtain that will function as a graphic display controlled by the rapid activation and deactivation of solenoid valves, which will cause segments of water to fall continuously, creating

The variety of water games that the screen can make will be very diverse and through open programming they can always be changing and evolve with technological innovations. These water games will form moving patterns, symbols, letters, numbers, images and moving figures. All possible varieties of games can be controlled by the different interactive devices arranged for this purpose. Device description

The graphic water screen is described in detail below by digital control.

The solenoid valves (11) are arranged at regular intervals. The assembly and disassembly of the same is done through a quick connection system (7) that allows individualized maintenance and reinstallation in an agile and simple way.

Each electr valve (11) is connected to a pipe (9) with pressurized water by means of an elastic hose (8) and is electrically powered by a plug-in connector (10) that allows a quick replacement of the valve in case of electrical failure. The body of the nozzles (1) is connected to the solenoid valve (11) by means of a quick joint system (5). The valve body (1) is fixed to the guide structure (12) by an adjustable fixing system (3) and (4).

The nozzles are assembled by joining systems (5) that allow easy access, disassembly, maintenance and subsequent rapid assembly. Function Description

The solenoid valves are arranged in battery forming the jets when parallel lines fall from a raised structure to the ground. The solenoid valves have a very fast response time and are activated and deactivated by a programmable logic system. The installation control software transmits the orders to “print” the graphics of water to the battery of solenoid valves so that they generate fragmented jets and empty spaces for each valve. The visual result is a digital graphic generated by water as it travels from the structure that supports the system to the ground. This invention could be considered as a "water plotter" that instantly "prints" digital water graphics, dynamic patterns, figures, symbols, texts, etc., according to the varied programming allowed by the software. Brief description of the drawings

To facilitate the understanding of what has been described in the previous sections, 1 drawing has been made.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement Claim 1 The document closest to the object of the invention is D01, said document presenting a method and device based on the concept of a graphic water display (Paragraph 3, line 54-Paragraph 4, line33). The device (Figure 9,10; Paragraph 7, line 18-line 67) comprises a water source (76), which supplies a pipe main (70), from which secondary pipes (72), each of which are connected to a single valve (14). The water supply system of each output terminal is regulated by an electronic control element (74). The incorporation of specific elements such as are established as differences of the present application with respect to D01 fittings, hoses or solenoid valves, said consideration is established of common knowledge in the state of the art which concerns us and therefore does not imply inventive activity. Finally, the use of hoses or pipes so that water can reach from the source to each of the terminals, is an aspect well known as it is revealed in all the documents cited in the report. Therefore, said claim is new (Article 6 LP) and lacks inventive activity (Article 8 LP). Claims 2-3 The use as well as the design of nozzles of the present application, apparently does not solve a technical problem, establishing itself as a mere design option. The aesthetics of water forms lack characteristics techniques The use of fast connection and disconnection systems is not common knowledge, not apparently establishing The solution to any technical problem. Therefore, these claims are new (Article 6 LP) and lack inventive activity (Article 8 LP). State of the Art Report Page 4/4
