Description

MOLD BLOCK FOR MANUFACTURING MODULAR EQUIPMENT AND METHOD OF MANUFACTURE

FIELD OF THE INVENTION The present invention relates to molded blocks for the manufacture of modular equipment. The blocks according to the invention comprise a main block body, said main body having in particular an upper surface, this upper surface being provided, on the one hand, with at least one corner and, on the other hand, with at least one a stop. The invention also relates to modular equipment comprising at least two blocks such as above, these modular equipment can be intended, in particular, for the practice of urban sports. Finally, the invention relates to a method of manufacturing molded blocks as defined above.

PRIOR ART Urban sports are practiced in particular environments. They often require adapted rolling stock. For example, skateboarding requires skateboards or skateboards. The practice of roller skating requires suitable roller skates or rollers. The practice of cycling requires bikes often adapted, including bikes called BMX. Urban sports are in particular based on sliding actions on a support, in particular on an edge of the support which requires that said edge be perfectly continuous, thus causing wear or even premature degradation of the support. These slipping actions are causing a wear of the support.

It is very common to find concrete structures, built by local authorities, dedicated to the use of urban sports. These structures are generally called leisure facilities. Recreational equipment is either built of concrete, on site, or built from prefabricated elements assembled with mortar. They are not scalable. Local authorities promote the creation of leisure equipment dedicated to multi-sport practices, which implies certain specificities, on the one hand, in terms of user safety and, on the other hand, in terms of modulation. However, the systems known from the prior art, have drawbacks in particular in terms of user safety and / or in terms of modulation.

Their adaptation to multisport practices is therefore limited. Equipment is disclosed in the patent document published under the number FR 2 754 281. This equipment comprises blocks provided with projecting parts and connecting holes ensuring their assembly for example by means of keys. Assembly and / or disassembly of the block assemblies is made possible without deterioration, thanks to said keys. However, such equipment does not provide adequate security because block assemblies are not strongly secured. This is in contradiction with the practice of urban sports. In addition, these systems do not provide edge continuity between two blocks.

Other equipment is composed of concrete blocks joined to each other by gluing, for example by means of a glue mortar. Such equipment does not allow in particular a mounting and disassembly of the blocks without deterioration. The adaptability to the support is moreover in contradiction with the continuity of edge.

The idea of modulation of leisure equipment is part of a current approach to encourage sports practice and in particular to the recognition, development, accompaniment and supervision of urban sports and new sports appeared in the last three decades. To date, there is no modular equipment, in the sense that the existing art is not modular at will, because the block assembly is currently not reversible. Nor there exists to date, modular equipment of heavy blocks, such as concrete, allowing edge continuity between two blocks, typically for urban sports slips along the edges. Discontinuity leads to increased risk for the user in terms of a dangerous fall.

SUMMARY OF THE INVENTION In view of the above, a problem to be solved by the invention is the production of molded blocks for the creation of modular equipment in a practical manner, these equipment having characteristics allowing the practice of urban sports especially.

According to a second aspect, the solution of the invention is a modular equipment comprising at least two blocks as defined above, characterized in that the interchangeable part is a connecting piece between two blocks filling the reservation and in that said two blocks are connected by said connecting piece fixed to the columns of said two blocks and ensuring continuity of edges. According to a third aspect, the solution of the invention is a method of manufacturing a block as defined above, characterized in that it comprises the following steps according to which: a mold having a mold bottom provided with an impression at the location of the reservation and a tube; the column is disposed substantially perpendicular to said mold bottom at the location of said imprint; we sink in the mold; and the block thus formed is demolded.

DETAILED DESCRIPTION OF THE INVENTION FIG. 1A shows a block 1 according to the invention. This block 1 is a molded block for the manufacture of modular equipment 2 as illustrated in FIG. The term modular equipment means, according to the invention, that such equipment is designed from basic elements, or modules, that can be assembled in different ways. Block 1 comprises a main block body 3, for example, substantially parallelepiped rectangle. In other examples, the block may be curved or may take any other form. Advantageously, the materials of the blocks according to the invention are made of concrete. Alternatively, the invention may also relate to heavy molded modular blocks comprising resin and / or ceramics and / or plaster and / or metal. In the example of FIG. 1A, the block 1 has an upper surface 4-1 and a lower surface 4-2. It has four sides: two short sides and two long sides. The upper surface 4-1 of the block 1 is provided, on the one hand, with at least one corner and, on the other hand, with at least one edge. In practice, this surface is provided with four corners and four edges. In Figure 1A, the edges are referenced 6-1, 6-2, 6-3 and 6-4 and the corners are referenced 5-1, 5-2, 5-3 and 5-4. According to the invention at least one corner 5-1, 5-2, 5-3, 5-4 and / or at least one edge 6-1, 6-2, 6-3, 6-4 presents a reservation 7 of material. In the advantageous embodiment shown in FIG. 1A, all the corners 5-1, 5-2, 5-3, 5-4 have a reservation 7 and the edges do not have such reservations. Typically, the length of the blocks 1 is between 0.50 and 3.00 m, their width between 0.30 and 1.50 m and their height, between 0.10 and 1.50 m. Moreover, the blocks 1 according to the invention have a specific weight of between 0.7 and 3 t / m 3. The modular equipment 2 according to the invention may for example be composed of two modules 1-1 and 1-2 as in Figure 1B. These two modules can be connected by a connecting piece 8-1 and 8-2. The corner piece 9-1, 9-2 makes it possible to fill the reservation 7 and prevents the premature wear of the block 1-1. As it appears in FIG. 2, an embedded column, before casting, in the block body 3 is disposed substantially perpendicular to the upper surface 4-1. In addition, this column opens into the reservation 7. The column typically comprises: a seat part 10 10, a sleeve 11, a tube 12, a second bushing 13, a screw 14, and a base 15. The part seat 10 is for example of substantially rectangular parallelepiped shape, provided with a top surface typically flat and pierced from one side to 15. It allows the corner pieces 9 and / or connecting pieces 8 to come into contact plane. This piece 10 is typically in sealed contact with the sleeve 11. The sleeve 11 is, without limitation, threaded to allow the attachment by the face of other parts. Its drilling does not necessarily open as shown in Figures 3A and 3B. The attachment in the sleeve 11 may be composed of a clipping system. The tube 12 typically makes it possible to create a tight connection between the bushing 11 and the bushing 13. The bushing 13 makes it possible in particular to screw and / or unscrew the screw 14. The base 15 is particularly intended for contact with the bushing. ground. The screw 14 is particularly intended for adjusting the height of the body of the block 3 relative to its support. Advantageously, the adjustment of this screw 14 is performed by means of a piece, for example, metal, through the column, before the connection 35 with another block. Thus, in a preferred but non-limiting embodiment of the invention, the diameter of the bushing 11 and / or the tube 12 is equal to or slightly greater than that of the bushing 13. The part 16 can be part of the column, in particular when the edge 6 of the block 1 comprises an angle 17. This piece 16 has a particular effect in the manufacturing process presented below. The interchangeable parts, as illustrated in Figures 3A, 3B and 3C, according to the invention are for example a lifting sling 18, the corner piece 9 or the connecting piece 8 between two blocks 1. The sling 18 is for example screwed into the sleeve 11. The corner piece 9 and / or the connecting piece 8 is for example fixed to the column by means of a screw 19.

The angle 17 is flush with the upper surface 4-1 of the block 1. It strengthens the wear resistance of the edge 6, in particular, during shocks and / or repetitive and / or regular rubbing. The column according to the invention may comprise a socket 20 in blind drilling, as shown in FIG. 4A. Such a sleeve 20 allows the attachment, for example, either by screwing a screw 19, a connecting piece 8 and / or an angle piece 9, or by screwing a lifting sling 18.

This FIG. 4A illustrates an advantageous embodiment of the invention, namely the use of several columns in a corner 5 or an edge 6. FIG. 4B shows the contribution of the plurality of columns to increase the joining of the assembly 30 of 2. Because modular equipment 2 according to the invention is an assembly of different blocks 1, these blocks 1 may have different technical characteristics of inclination of their upper surfaces 35 with respect to the support.

Thus, an advantage of the present invention is to allow a modular adjustment of each block relative to its support, more than a setting blocks between them. It has also been shown that the filling of the reservation 7 between two blocks 1 advantageously allows the continuity of edges between these two blocks. The block 1 manufacturing method according to the invention comprises the following steps according to which a mold 21 is provided having a mold base 22 provided with a wedge 23 and / or an edge 24 as well as a fixing tube 25 at the location of a footprint 26 as shown in Figure 5A. Preferably, the footprint 26 is placed in a corner of the bottom of the mold 22.

As is illustrated in FIG. 5B, the column 27 is disposed substantially perpendicular to the mold base 22 at the location of the cavity 26. The column 27 is preferably screwed onto the tube 25 so as to create a substantially vertical force , that is to say substantially perpendicular to the mold bottom. Finally, as shown in FIG. 5C, the material is cast into the mold and then demolded.

To allow the column 27 to remain substantially perpendicular to the mold base 22, it is subjected to the vertical force. As a result, no amount of material in the liquid and / or gaseous phase included in the material can be introduced between said upper surface of the mold base 22 and said column 27. In the case of concrete blocks, the quantity of material in the liquid phase is a concrete milt. In a preferred embodiment of the present invention, the angle iron 17 is placed at the bottom of the mold along the edge 24. The column 27 is then positioned on the column 25 so that the angle 17 is blocked by a substantially vertical pressure. the bottom of the mold 22. To accelerate the evacuation of air in the molding material, once it is poured into the mold 21, it is possible to vibrate the mold 21 and / or the material itself. In particular, the invention makes it possible, during the step of vibrating the mold 21, to prevent a displacement of the parts contained in the material of the future block, in particular the angle iron 17. Thus, if the present invention relates to concrete, then the concrete milt can not be introduced between the angle 17 and the mold base 22. The particular effect provided by the method according to the present invention is that the angle 17 is flush with the upper surface 4-1 of the block 1 Once it is removed from the mold. An advantage of the present invention lies in the ability and ease with which a heavy block can be positioned. The positioning is particularly precise and avoids any degradation of the block. Indeed, for the positioning of the block according to the invention, it is not necessary to use a load lift truck. A load-lifting truck is typically composed of a fork which is inserted under a load to be able to then move it. To position a block according to the invention, it suffices to: place a sling 18 on a block in a column at the location of the reservation; using a load gate to lift said block by means of said sling; and to perform a pendulum positioning of said block.

Typically, we will put a sling 18 in each corner of a block. We can then choose a hook anchor to connect these slings, for example, we can choose a beam-shaped anchor.

Then simply connect the slings and / or the anchor with the load door. Finally, the pendulum positioning of the block is carried out. Note that pendulum means that the block is suspended from the load door by means of slings. Pendulum positioning is a particular advantage of the present invention because it is accurate and because it does not cause degradation of the block. It will be noted in particular that the positioning method is advantageous in the use of the column 27 incorporated before casting, in the block body 3. In fact, following the positioning of a block 1 according to the invention, it is possible to remove the sling 18 to position, in the reservation, either a corner piece 9 with its screw 19, or a connecting piece 8. The filling of the reservation then makes it possible to camouflage the column. In the particular case of concrete blocks 1 and a column 27 comprising in particular a lifting bush 11, a tube 12, a second bushing 13 and a screw 14, an advantage of the present invention is the use of said bushing lifting for purposes other than those for which it is predestined. These other purposes are for example the attachment of the connecting piece 8 or the attachment of a corner piece 9 or an accession to the screw 14. Thus, when the connecting piece or the corner piece is positioned, the socket is camouflaged.
