Manufactured road marker for pedestiran crossing and all kinds of roadways

Abstract

The invention relates to road markers for pedestrian crossings and roadways. A plurality of frame structures consisting of rods are connected by cross members, said frame structures being close to each other lengthwise and crosswise in order to obtain manufactured-items made up of a plurality of solid color porcelainized stoneware blocks, said blocks being further slidable inside the above mentioned frame structures employing said rods as guide members.

1 . A road marker for pedestrian crossing areas and roadways consisting of a plurality of blocks close to each other, wherein said marker comprises:
 a plurality of frame structures, each consisting of guide means tightly secured to one or more cross members; said frame structures being adapted to be fixed onto a layer of cement cast on the ground;   a plurality of solid blocks, each of said blocks being securable to the frame structures and being slidable inside said frame structures following the guide means.

       6 . (canceled) 
   
   
       7 . The road marker according to  claim 20 , wherein each block has a lower portion and an upper portion adapted to be flush with the road surface, both said portions having their width smaller than the gap between the two pairs of rods of the frame structure; a central portion having its height smaller than the gap between the two rods making up each of the two pairs of rods and having its width greater than the distance between the above mentioned two pair of rods and smaller than the gap between the two short vertical sides of each cross member. 
   
   
       8 . The road marker according to  claim 1 , wherein each block is made of ceramics or glass paste, resins, cements and its by-products or powders from processings such as, for example, smoothing and milling processes. 
   
   
       9 . The road marker according to  claim 1 , wherein in a plan view, the upper portion of each block has a square configuration, said configuration ensuring the best performance of the surface itself in terms of traffic. 
   
   
       10 . The road marker according to  claim 1 , wherein in a plan view, the upper portion of each block has a configuration of any shape. 
   
   
       11 . The road marker according to  claim 1 , wherein the upper portion surface of each block adapted to contact tires or to be the walking surface is smooth finished. 
   
   
       12 . The road marker according to  claim 1 , wherein the upper portion surface of each block adapted to contact tires or to be the walking surface has knurled finishing or a slantwise raised pattern; said knurling and said slantwise raised pattern can show either a parallel trend or be mutually angled. 
   
   
       13 . The road marker according to  claim 1 , wherein on the bottom of the lower part of each block there is a plurality of grooves parallel, angled or perpendicular to each other. 
   
   
       14 . The road marker according to  claim 1 , wherein a plurality of reinforcing rods is tightly secured onto the long horizontal side of each cross member being part of the frame structure.

       16 . (canceled) 
   
   
       17 . The road marker according to  claim 1 , wherein during the laying operation, the frame structures ( 1 ) are located in place either one by one or side by side lengthwise or sideways so as to leave a hollow space at least one centimeter thick between said frame structures. 
   
   
       18 . The road marker according to  claim 1 , wherein in order to make pedestrian crossings, a plurality of groups of structures filled in with blocks is provided; each of said group of structures being made up of four frame structures lined up sideways and tightly secured to each other by welded seams in coincidence with the short vertical sides mutually touching. 
   
   
       19 . The road marker according to  claim 1 , wherein said guide means consist of a couple of rods tightly secured to said cross members. 
   
   
       20 . The road marker according to  claim 1 , wherein said guide means consist of two pairs of rods tightly secured to said cross members. 
   
   
       21 . The road marker according to  claim 19 , wherein the rods of each frame structure are parallel to each other. 
   
   
       22 . The road marker according to  claim 20 , wherein the rods of each frame structure are parallel to each other. 
   
   
       23 . The road marker according to  claim 19 , wherein the cross members, to which the rods are tightly secured, are U-shaped having their opening facing said rods when the frame structures are installed. 
   
   
       24 . The road marker according to  claim 20 , wherein the cross members, to which the rods are tightly secured, are U-shaped having their opening facing said rods when the frame structures are installed. 
   
   
       25 . The road marker according to  claim 1 , wherein the frame structures comprise a plurality of said cross members. 
   
   
       26 . The road marker according to  claim 25 , wherein each frame structure is provided with a stop member tightly secured to the last cross member  3 . 
   
   
       27 . The road marker according to  claim 1 , wherein each block is made of porcelainized stoneware.
