Description

This invention relates to a load-bearing structure for a shelving unit. Load-bearing structures for shelving units are known, distinguished by their assembly method, degree of structural modularity, and maximum load-bearing capacity of the constructed shelving. Generally, known types of structures employ vertical upright members as a support base on a stable surface, and obtain a suitable support structure using appropriate fasteners that can be coupled to such upright members. These structures are used in both the household and commercial sectors to store, display, and/or organize various types of products, and their volume, weight, and size vary greatly depending on the nature of the product itself. Therefore, this type of load-bearing structure employs a fastening system adapted to combine different types of upright members and fasteners, forming a modular load-bearing structure capable of accommodating different products according to user needs. Generally, such a fastening system comprises a fastening opening formed in a vertical upright member and a fastening portion formed in the fastening body. The fastening portion is insertable into and connectable to the fastening opening, thereby enabling the vertical upright member and the fastening body to be fastened together. This type of load-bearing structure is susceptible to improvements in terms of stability and strength. In practice, the structural load acting between a fastener and a vertical upright member generally includes at least one longitudinal compressive component that pushes the fastener longitudinally along the vertical member, and a lateral rotational component that rotates the fastener around the vertical member. However, the first fastening mechanism used in this type of load-bearing structure comprises a single fastening element. The fastening element is inserted into the fastening opening and positioned to support the lower edge to be fastened. Therefore, the lateral rotational component tends to pivot on the fastening element and rotate the latter within the fastening opening. Such rotation can cause deformation of the fastening element and/or rotation of the fastener around the vertical upright member, thus potentially impairing the distribution of structural loads among the components of the load-bearing structure. These drawbacks make known load-bearing structures unstable and fragile, reducing their maximum allowable load and ultimately leading to a shrinking market. Other features and advantages of the present invention will be further clarified from the description of preferred and non-limiting embodiments of the load-bearing structure for a shelving unit. These features and advantages are shown in the accompanying drawings as non-limiting examples. The drawings are as follows. Figure 1 is an exploded view of the load-bearing structure for a shelf set according to the present invention. Figure 2 is an axonometric view of the load-bearing structure for a shelf set according to the present invention. Figure 3 is a detailed diagram of some of the components of the load-bearing structure for a shelf set according to the present invention. Figure 4 is an axonometric view of another embodiment of the load-bearing structure for a shelf set according to the present invention. Referring specifically to the drawings, reference numeral 1 indicates the load-bearing structure for the entire shelving unit. Load-bearing structure 1 for the entire shelf set is, - At least one longitudinal wall 4, and at least one vertical upright member 2 provided with at least one fastening opening 3 formed along the longitudinal wall 4, - At least one fastening body 5 is provided with at least one fastening wall 6 and at least one fastening portion 7, 8 cantilevered to the fastening wall 6, Equipped with, The fastening parts 7 and 8 are insertable into the fastening opening 3 and are slidable within the fastening opening 3 between a fastening configuration in which the vertical upright member 2 is fastened to the fastening body 5 by the fastening parts 7 and 8 being coupled to the fastening opening 3, and at least one release configuration in which the vertical upright member 2 is released from the fastening body 5 by the fastening parts 7 and 8 being released from the fastening opening 3. Preferably, the vertical upright member 2 is a known type of upright member, and when in use, it is positioned on the ground surface and extends vertically in the longitudinal direction. Furthermore, the vertical upright member 2 is provided with multiple outer perimeter walls 9. These multiple outer perimeter walls 9 are arranged continuously with respect to each other and, together with the longitudinal walls 4, define the structure of the vertical upright member 2. Preferably, the longitudinal wall 4 and the fastening wall 6 have a substantially flat three-dimensional structure. In this manner, the longitudinal wall 4 and the fastening wall 6 are arranged in a fastening c
