Title: Constructive provision applied in protective coat for sports court

Description:
TECHNICAL FIELD 
     The following descriptive report for utility model refers to the development of a protective cover for sports courts, where a channel is built all around the total perimeter of the court, that channel serves as a means of water runoff, to the water that was captured by the roofing placed over the court; while that roofing is kept high and held on to the court by suitable attachment means 
     STATE OF THE ART 
     Roofing with tarps for sports courts are well known, particularly in tennis courts. These roofing comprise a canvas of large proportions that is unrolled over the sports court to be protected. 
     The document MU 8001562-0 LUCAS (2000) reveals a retractable manual cover for sports court with permeable floor, comprised of two tubes are stored at the back of the court and are surrounded by canvas they allows the at this moment the passage of water beneath them, by using the parts that suspend the reels when stored in the background. 
     ANNONI (2008) shows the MU 8802902-6 a canvas cover comprised of two parts which overlaps on the sports court, so as to protect it against rain water, allowing its use immediately after the rain stops. The closure of the canvas is with Velcro, with rubber on the sides and to keep it attached to the ground sandbags are used in corners of the court. It&#39;s also provided a layer of protection to be embedded to the intermediate net; besides, steel rebar around the court, inside the channels, to fix the loops. 
     A of protective covering system for sports courts or similar is described in the PI 9901044-5 LIMA (1999), which uses basically a winding tube, on which is fixed one of the ends of the protective cover, and the other end is fixed on the grid of the water collecting box, which provides a drop for water and dirt runoff directly to that collector box, as well as allows the cover to of on the tube, covering or uncovering the court or pool, providing a uniform winding/unwinding of the cover, and such action can be done automatically through the use of a motor reducer, or manually when done by the users themselves. 
     DISCUSSION 
     Thus, due to the considerations pertinent to the state of the art discussed above; is one of the objectives of the constructive provision applied in protective cover for sports court, the employment of a channel which goes around the perimeter of the court, to capture rainwater to lead it to culverts (not shown. The tarp covering the court becomes stretched over it through pins that are connected to sockets on the ground. 
     Moreover, it is foreseen the use of supports so that the canvas cover is inclined like a roof, causing the water rain to drain much faster. 
    
    
     
       LIST OF FIGURES 
       The characterization of this document this for the patent of utility model is made by representative drawings of the constructive disposition applied in protective coat for sports courts, so that the cover can be fully reproduced by proper technique, allowing full characterization of the functionality of the object sought. 
       From the figures elaborated that expresses the best form or preferred form to make the product here idealized, is founded the descriptive part of the report, through a detailed and consecutive numbering, where this clarifies aspects that may be implied by the representation adopted in order to clearly determine the protection required herein. 
       These figures are illustrative only and may vary, and as long as they don&#39;t Depart from the initially pleaded. 
       In this case one has to: 
         FIG. 1  illustrates a cut in a cover made according to the provisions of the proposed model, showing the structure support of the canvas cover; 
         FIG. 2  shows a detail of the point of attachment of the canvas in the gutter for water drainage; 
         FIG. 3  shows a court covered with canvas. 
     
    
    
     DESCRIPTION 
     A preferred way of realization comprises a canvas cover ( 1 ) to cover an entire sports court ( 2 ), where such bag is placed on stringers ( 3 ), where these stringers are sustained by supports ( 4 ), and the mentioned supports ( 4 ) present decreasing length from the net ( 5 ) separating the courts, on a tennis court until, the extreme edges ( 6 ), where these extreme edges ( 6 ) the mentioned canvas cover ( 1 ) passes the slopped stringers ( 3 ) and is attached to the inside of the chute ( 7 ) by pins ( 8 ) arranged in the wall inclined ( 9 ) inside of said chute ( 7 ).
