Definitions

  • the present invention relates to a shelf, particularly but not exclusively useful for metal sets of shelves.
  • BE-A-781 831 discloses a shelf having a combination of structural elements as defined in the appended claim 1.
  • Metal sets of shelves of various shapes, models, and sizes are currently increasingly widespread and are particularly useful both in the industrial field and in household appliances.
  • a variety of structural reinforcements has been conceived for this purpose, ranging from various kinds of folding of the edges of the shelves to the application of auxiliary reinforcements constituted substantially by longitudinal profiles or tubular elements fixed below said shelves.
  • edges of the shelves are currently conventionally folded so as to form a box-like reinforcement having a quadrangular cross-section, the edge flap whereof is welded, usually by spot welding, to the lower surface of the corresponding shelf.
  • auxiliary reinforcements they are currently constituted, as described above, by longitudinal elements that are usually supported by appropriately shaped edges of the shelf.
  • the most commonly used cross-section is omega-shaped, with its base wings arranged against the upper surface of the shelf.
  • a negative consequence thereof is the tendency of the wings to open out when the shelf is loaded.
  • the aim of the present invention is to solve the described drawbacks of conventional models of sets of shelves, particularly by providing a shelf that offers a high ratio between mechanical strength and weight.
  • an object of the present invention is to provide a shelf the production whereof does not require welds with their corresponding drawbacks.
  • Another object of the present invention is to provide a shelf that can be produced in a wide variety of models and dimensions, and the structure whereof can be adapted to the different requirements to which it can be assigned.
  • Another object of the present invention is to provide a shelf in which any auxiliary reinforcement means can be applied in a stable manner and easily without however having position-shifting problems.
  • Another object of the present invention is to provide a shelf that can be installed easily and the manufacture whereof does not require specialized labor.
  • a shelf particularly for metal sets of shelves, of the type obtained by cutting and plastic deformation from metal plate, according to the invention, is generally designated by the reference numeral 10.
  • edge regions 11 of two mutually opposite reinforcement sides 12 each edge region being shaped so as to form three parallel longitudinal folds 13, 14, and 15, forming a corresponding structural reinforcement designated by the reference numeral 16.
  • the structural reinforcement 16 has a cross-section shaped like a right-angled triangle with one side 17 parallel to said shelf 10.
  • a fourth fold 18 of the free end 19 of each one of the edge regions 11 forms an edge flap 20 that abuts against the lower surface of the shelf 10.
  • the reinforcement sides 12 correspond to the longer sides of the shelf 10, which has a rectangular shape.
  • the shelf 10 also comprises two complementary sides 21, in this case the shorter sides, that are C-shaped and have their concavities 22 directed inwards.
  • Each one of the complementary sides 21 has a corresponding edge flap 23; means for anchoring to a corresponding structural reinforcement 16 are formed at the ends of said edge flap 23 and are constituted in this case by two tabs 24 formed by cutting.
  • each one of the two tabs 24 is formed at one of the ends of the corresponding edge flap 23; upon assembly, it is deformed so as to enter a through hole 25, formed in a flap 26 that corresponds to the side 17, and lock therein.
  • Each one of the structural reinforcements 16 furthermore comprises a flap 27 that is perpendicular to the shelf 10 and a diagonal flap 28 that ends at the inner part of the fold 13, which forms the flap 27 with respect to the shelf 10.
  • the shelf 10, in this embodiment, also comprises auxiliary reinforcement means constituted by three identical longitudinal supporting elements 29.
  • Each one of the supporting elements 29 has a cross-section that is shaped like an isosceles trapezoid and is open at the shorter parallel side, designated by the reference numeral 30.
  • each one of the supporting elements 29 that corresponds to the shorter parallel side 30 is in contact, upon assembly, with the lower surface of the shelf 10.
  • each one of the supporting elements 29 is inserted in, and supported by, the complementary sides 21.
  • each one of the supporting elements 29 is shaped so as to form, at each one of its ends and at the surface corresponding to the longer parallel side 31, a seat 32 that is formed by plastic deformation and in which a corresponding stud 33, also formed by plastic deformation in the corresponding edge flap 23 of a corresponding complementary side 21, fits upon assembly.
  • the longitudinal opening of the shorter parallel side 30 has curled edges so as to form two opposite and substantially parallel flaps 34 directed towards the inside of the supporting element 29.
  • the isosceles-trapezoid shape of the supporting element 29 and its particular arrangement below the shelf 10 causes it to tend to close, with a consequent increase in strength, as the load increases.
  • each reinforcement is formed by providing the folds 18, 13, 14, and 15 according to a preset sequence.
  • the folds 14 and 15 and part of the fold 18 are formed simultaneously.
  • the fold 18 is in fact completed only after forming the fold 13.
  • auxiliary reinforcement means that can optionally be used in the shelf according to the invention can be placed very easily by the operator but at the same time have extreme positional stability even if they are subjected to considerable and intense loading and unloading cycles of the corresponding shelf.
  • the materials and the dimensions may be any according to the requirements.
