Definitions

• the invention fits in the technical field concerning fitting out of commercial vehicles used to transport items.
• this load surface e.g. with plywood, using segments of wood of appropriate size, which are arranged consecutively juxtaposed to one another by connections, which ensure continuity between the segments and preventing at least the possibility of relative movements in a direction perpendicular to their bearing top surfaces.
• connection systems applied at the time of assembling, or by providing real connection joints, such as male-female ones, along the facing edges of the segments to be connected.
• connection joints such as male-female ones
• the two members of the junction are applied to these edges with interlocking systems, which involve separate execution of the coupling to the single edge of each element, male or female, usually made from metal.
• edges of various segments must be processed separately and care must be taken to properly distribute the various male-female member on the segments, in order to match the correct coupling between the segments themselves during assemblage.
• the object of the present invention is to overcome these problems in accordance with the contents of the claims.
• FIG. 1 shows a perspective overall view of a bearing surface incorporating the invention
• FIG. 2a shows a portion of a cross-section taken along the tracing line ll-ll of Figure 1 ;
• FIG. 2b shows a portion of a cross-section taken along the tracing line ll-ll of Figure 1 , in which the connection members are shown separated, before coupling thereof;
• FIG. 3 shows a portion of a cross-section taken along the tracing line Ill-Ill of Figure 1.
• numeral 1 indicates a flat modular element designed for assembly with other modular elements to form a load surface of commercial vehicles and the like.
• the flat elements 1 are assembled consecutively by juxtaposing one to another by means of connections indicated as a whole by numeral 3.
• connection 3 includes at least one connection members in the form of a section 2, which is straight with constant cross-section, at least as regards its contour, and has coupling recesses 20 which are symmetrically opposed to each other with reference to a median longitudinal plane of the same connection member 2.
• the coupling recesses 20 are so shaped that mating extremities 10 of the edges of said flat elements 1 , consecutively set close to each other, are perfectly fitted therein.
• the recesses 20 are geometrically identical to each other and have cylindrical shape with constant cross section, preferably in the form of circle arc.
• the coupling recesses 20 and the mating extremities 10 of the edges of the flat elements 1 have such a shape as to establish a coupling designed to prevent the two flat elements 1 set close to each other from moving with respect to each other in directions perpendicular to the planes that they define.
• the shaped extremities 10 of the edges of the flat elements 1 have cylindrical shape, complementary to that of the coupling recesses 20, whose generatrices are set parallel to the longitudinal middle axis of said connection member 2.
• the generatrices of the cylindrically shaped ends 10 of the edges of the flat elements 1 are parallel to said flat elements 1.
• Each of the coupling recesses 20 is delimited by lug portions 21 with at least partially convex extremity portions, designed to precisely mate with corresponding concave portions 11 of each correspondingly shaped single end 10 of the edges of the flat elements 1 , consecutively juxtaposed to one another.
• connection member in the form of section 2 is delimited by two flat surfaces 22, parallel to each other and symmetrically opposite with respect to a longitudinal midplane perpendicular to the longitudinal symmetry midplane of said coupling recesses 20.
• the coupling recesses 20, with their lug portions 21 having at least partially convex extremity portions, are sized to receive, with said precise coupling with the corresponding concave portions 11 of each single said shaped ends 10, so that the planes 12 delimiting said flat elements 1 are coplanar with the flat surfaces 22 delimiting said connection member 2 in form of section.
• connection it is enough to shape the extremity edges of the flat elements 1 , so as to form the shaped ends 10 with their concave portions 11.
• Shaping operation is particularly easy and fast because it is performed by a machine with a standard milling operation of the same by using a special shaped cutter. The operation is repeated identically, using the same tool for the edges to be matched of all the flat elements 1.
• the other edges, which do not have to be mutually joined in the connection, such as the outer edges, will be finished with different operations, for example by including closure elements or flanges 4 as shown in Figure 3.
• connection members 2 Once the shaped ends 10 have been obtained with the concave portions 11 (and possibly with their surfaces protected by applying a layer of protective paint), the flat elements 1 are ready to be assembled with the connection members 2, by juxtaposition coupling of the shaped ends 10 of two flat elements 1 with the coupling recesses 20 of a connection member 2. The bearing surface is then simply mounted by juxtaposition by matching consecutively one flat element to another with the interposition of a connection member 2.
