Definitions

  • the present invention relates to a basement to be used for support of tables, or the like. More specifically, the present invention relates a basement of particularly firm kind and comprised of a minimal number of modular members having particular use for supporting pieces of furniture, such as tables or the like.
  • the present invention intends to be just an improvement to the central basements.
  • any solid such as a pyramid having a polygonal regular base, has a great support stability on the ground.
  • the tetrahedron which is a particularly regular solid figure having four faces consisting of four equilateral triangles, has a symmetry assuring a very high support stability, as any face can operate as a base.
  • the basement can be inscribed in a pyramidal figure, provided with four apexes coinciding with the four apexes of a tetrahedron, a particular stability of the basement is obtained, in accordance with the principle of the building members, known as "tetrapod", used for the construction of artificial cliffs, which are always stable independently from the orientation having at the time of their laying.
  • tetrapod used for the construction of artificial cliffs
  • a basement consisting of a upright central stem provided with a bottom base and a top base, the bottom base housing some cavities into which can be inserted the ends of a plurality of so-called tubular legs, because they consist of a bent pipe, all each other identical, being the cavities equal in number with respect to the ends of the tubular legs and the top base also housing some cavities equal in number with respect to the cavities of the bottom base to receive an equal number of inserted sleeves to be fastened under the support plate of a table top, or the like.
  • the number of cavities in the bottom base of the stem is double than the number of tubular legs, because the cavities house the two ends of the same tubular legs.
  • the bottom base of the stem houses six cavities for receiving the ends of three tubular legs equi-angularly arranged (that is 120° staggered) around the stem.
  • the top base of the stem houses six inserted sleeves, arranged as three side-by-side arranged pairs also aligned with the ends of the three tubular legs, being the sleeves provided with fastening means to the support plate of the table top.
  • the holes of the sleeves are threaded and the fastening means of the support plate are screws passing through the holes in the plate itself.
  • a pair of basements is carried out, being the pair formed by two side-by-side arranged stems, anyone provided with bottom and top base, housing the bottom bases cavities for receiving the inserted ends of tubular support legs and the top bases cavities for receiving sleeves fastening a pair of plates co-operating to form a table top support, lacking anyone of the two side-by-side arranged stems of the pair of basements a tubular leg and the cavities housing the ends thereof, a portion housing the lacking cavities being replaced by an axial joint notch, connecting both bases, suited to house a rigid beam providing to connect the two stems of the basements.
  • the sleeves inserted in the top bases of the two stems are equal in number to the ends of the tubular legs to which they are aligned and carry fastening means crossing the support plates of the table top.
  • the sleeves are provided with axial threaded holes and the fastening means are screws, passing through holes in the support plates of the table top, and engaged in the same threaded holes.
  • a basement 10 consists of a stem 12 which, in the present embodiment, is of triangular lobed shape.
  • a stem 12 is a draw piece provided with cavities for housing in insertion, in a bottom base a plurality of upper ends 14, 14a, 16, 16a and 18, 18a of tubular support legs 20, 22 and 24 and, in a top base a plurality of sleeves 26, 26a, 28, 28a and 30, 30a which, by means a corresponding plurality of screws 32, 32a, 34, 34a and 36, 36a, fasten a plate 38 to the stem 12 to support a table top, or the like.
  • a basement 10 can be inscribed in a tetrahedron and similarly operates.
  • a tetrahedron TH has four apexes V 1 , V 2 , V 3 and V 4 , the apex V 1 falling at the centre of the cluster of sleeves 26, 26a, 28, 28a and 30, 30a, the apex V 2 falling at the centre of the foot of the leg 20, the apex V 3 falling at the centre of the foot of the leg 22 and the apex V 4 falling at the centre of the foot of the leg 24.
  • the centre of gravity C of the equilateral triangle having apexes V 2 , V 3 and V 4 is vertically aligned with the upper apex V 1 of the tetrahedron TH, assuring an outstanding stability of the basement 10.
  • a pair 50 of basements provided with stems 52, 52a having fastened tubular support legs 60, 62 and 60a, 62a, respectively, and sleeves 66, 66', 68, 68' and 66a, 66a', 68a, 68a', respectively, to fasten two plates 70, 70a co-operating to form a table top support , or the like.
  • the two stems 52 and 52a are provided with two joint notches 72, 72a into which can be inserted a rigid beam 74 connecting the two beams 52 and 52a, being the beam fastened to the notches 72, 72a by means of common well known means, such as screws, bolts, or the like (not shown).
  • tubular legs 20, 22, 24, as depicted in the Figures 2 and 3 can be used a higher number, such as four, five or six, although this higher number is not particularly attractive, because just by three legs is obtained a structure of the kind called "redundant", assuring a particularly good support stability.
