| 摘要 |
<p>The present patent application concerns the production, by pressing from plastic or similar materials, of special coloured markers, incorporated in suitable supports buried deep in the ground, with which it is possible to produce boundary lines for sports fields or the like, that are no longer subject to deterioration and last significantly longer than all lines that are up to now marked with paints or powders. Essentially, the colouring element according to the invention consists of a support 2 comprising a series of tapered fins 3, essentially forming a cone with the vertex pointing downwards, forming a point underneath to facilitate its insertion into the ground and on the top a series of horizontal planes 4, arranged in rays, with vertical seatings 5 in which are inserted sets of flexible colouring material 6, formed by wires, strips or the like, arranged in bundles to form a kind of artificial grass, for example coloured white, that project from the ground. <IMAGE></p> |
