Definitions

• TITLE MANUFACTURED-ITEMS MAKING DEVICE FOR PEDESTRIAN CROSSINGS AND ALL KINDS OF STREET FURNITURE
• these pedestrian crossings can be simply made by colouring the road bed or by using, for example, porphyry or marble blocks, differently coloured.
• a first drawback is represented by the poor visibility soon reached by paints, particularly the white paint, due to oily solutions and above all to tyre rubber deposit. Said first drawback becomes even more relevant in bad weather when on the road bed, slippery with rain, pedestrian crossings become hardly visible.
• a second drawback is specifically related to pedestrian crossings made of porphyry or marble blocks; with heavy traffic and particularly with heavy loads, marble blocks break up and, in any case, either marble and porphyry blocks are likely to be removed from their respective seats thus creating craters in the pavement.
• the foregoing drawbacks give birth to a further problem represented by cases and damage claims for accidents due both to poor visibility of the pedestrian crossing and to the presence of potholes.
• the device for making manufactured-items for pedestrian crossing areas and street furniture of the type consisting of a plurality of blocks close to each other which is the object of the present invention, is characterized in that it combines:
• each of said blocks being securable to the frame structures and being slidable inside the aforementioned frame structures following the guide given by the two pairs of rods.
• FIG. 1 shows a block fitting the frame structure
• - figure 2 shows a cross section of the frame structure coupled to a block
• - figure 3 shows a block having a smooth upper surface
• number 1 refers to a frame structure made of metal consisting of two pairs of rods 2 parallel to each other and tightly secured to each other by a plurality of cross members 3; number 4 refers to a stop member tightly secured to the last cross member 3 of the frame structure 1; number 5 refers to a plurality of reinforcing rods; number 10 refers to a block.
• a pair of rods means two rods placed on the same short vertical side 3a of each cross member 3.
• Each of said cross members is U-shaped, with its opening upwards, that is towards the aforementioned rods 2; the securing points between rods 2 and the cross members 3 are located in coincidence with both the short vertical sides 3a of each of the aforementioned cross members.
• the stop member 4 is tightly secured to the last cross member 3 in coincidence with the short vertical side portions 3a between the two pairs of rods 2.
• Said stop member 4 performs the function of stopping the sliding of the first block 10 inserted into the frame structure 1.
• a plurality of reinforcing rods 5 is tightly secured onto the long horizontal side 3b of each cross member 3; these rods make the frame structure 1 more stable and prevent the mutual displacement of the cross members 3.
• the above mentioned plurality of reinforcing rods 5 may be omitted without affecting the performance of the present invention.
• the solid colour porcelainized stoneware block 10 has a lower portion I 1 an upper portion 8 and a central portion 9.
• portions 7, 8 and 9 have a square configuration.
• each block 10 is shaped in such a way that:
• the height of the central portion 9 is smaller than the gap between the two rods 2 making up each of the two pairs;
• the width of the central portion 9 is greater than the distance between the two pairs of rods 2 and lower than the gap between the two short vertical sides 3a of each cross member 3; - both lower portion 7 and upper portion 8 width is smaller than the gap between the two pairs of rods 2 of the frame structure 1.
• each block 10 has a smooth finishing but, as shown in figure 4, it might also be irregularly knurled or it might show a slantwise raised pattern.
• the blocks 10 could be of any colour even making use of fluorescent pigments.
• Figures 5, 6, 7 and 8 show a second embodiment of the present invention and specifically:
• FIG. 5 is a cross section of said second embodiment of the present invention.
• - figure 6 shows the block and the frame structure of the second embodiment
• - figure 7 shows a block of the above mentioned second embodiment having a smooth upper surface
• FIG. 8 shows a block of the above mentioned second embodiment having a knurled upper surface.
• Said second embodiment is different from the preferred one, as shown in figures 1, 2, 3 and 4, being characterized as follows:
• the frame structure is made up of two rods 2 parallel to each other and tightly secured to a plurality of cross members 3 in coincidence with the short vertical sides 3a of each said cross member, as shown in figure 5;
• each block 10 is shaped as illustrated in figures 5, 7 and 8 where the height of the central portion 9 is greater than the thickness of the rods 2 and its width is smaller than the gap between the two rods 2; moreover the width of both the upper portion 8 and the lower portion 7 is greater than the distance between the two rods 2.
• the second embodiment provides the upper portion surface 8 to be smooth finished, as shown in figure 7, or irregularly knurled, as shown in figure 8 or having an irregular slantwise raised pattern.
• each frame structure 1, necessary to create the manufactured item will be filled with the blocks 10 making said blocks slide along the rods till the first block so fitted in hits the stop element 4; each frame structure will thus be filled in with the blocks inserted one after the other, each hitting the previous one .
• the road surface to be covered with blocks 10 has been prepared at a depth slightly greater than the thickness of the device object of the present invention, it will be covered with a cement casting, either a cement grout or in solid phase and the frame structures provided with the blocks, when ready, will be supported there.
• the frame structured 1 including the blocks 10 can be located in place either one by one or side by side lengthwise or sideways so as to leave a hollow space at least one centimetre thick among the above mentioned frame structures.
• the number of the frame structures, filled in with blocks used in the laying step will vary depending on the extent of the manufactured item to create.
• a first advantage of the present invention is that pedestrian crossings and street furniture areas can be quickly set up.
• a second advantage is that the colours used for the blocks prove to be fast even in severe situations of wear as porcelainized stoneware is solid colour which results in good long lasting visibility; in this connection it is worth noticing that porcelainized stoneware reconditions through smoothing.
• a further advantage is offered by the device strength due to a series of reasons: the frame structures provided inside the device, the material each block is made of and the fact that the device as a whole is blocked by the upwardly flowing cement casting which will cover all the joints between the blocks and the hollow spaces existing between the frame structures.
• a further relevant advantage is that the frame structures, making up the device which is the object of the present invention, require easy and inexpensive manufacturing methods; also the laying step of the present invention can be easily and quickly performed.
• the description clearly refers to porcelainized stoneware blocks the device object of the present invention proves quite effective even when the blocks are made of not stonewared ceramics, glass paste, resins, cement and its by-products, powders from processings such as milling and smoothing processes, for example.
• frame structures are made of metal but it is clear that the device may be fully effective even using frame structures made of hard plastics.
• the description specifically mentions frame structures consisting of rods parallel to each other tightly secured to a plurality of U-shaped cross members.
• the device object of the present invention works efficiently even if said plurality of cross elements is replaced with a simple U- shaped metal sheet which it might be perforated or with a U-shaped wire net.
