Definitions

  • the finding also concerns a process for making it.
  • Carbon fibre bicycle frames can be made, substantially, according to three different construction types:
  • tube-to-tube frames are made with single preformed tubes glued together through strapping, which uses carbon straps impregnated with epoxy resin.
  • joind frames consist of single tubes, which are joined together through preformed joins having a single or double shell and fixed with epoxy glue.
  • - “monocoque” frames differ from the previous ones in that the components that form the front triangle constitute a single piece or “monocoque” to which the assembly consisting of the brackets and the chainstays, both right and left, and the relative opposite forks, adapted for supporting the wheel, is glued, through epoxy glue.
  • the purpose of the present finding is to make a carbon fibre bicycle frame that does not have the drawbacks of similar known products.
  • the purpose of the finding is to make a carbon fibre bicycle frame, in particular for racing bicycles, for professional and recreational use, with high performance and technologically highly evolved.
  • Such a purpose is accomplished by making a carbon fibre frame built completely in a single piece and obtained through extraction from a single mould. Constructively, all of the components that form the frame structure do not have any mutual join, all being made in the same mould and at the same time.
  • the frame according to the finding is in the form of a hollow structure, in which the outer walls are shaped inside a mould to form its shape and where the thickness and the structure of said walls vary as a function of the requirements of strength, rigidity and elasticity required mechanically at the different points of the structure itself; only the two rear forks differ, which are also integrated with the rest of the frame and moulded at the same time inside the same mould, which however, due to their function of supporting and fixing the pin group of the rear wheel and also for their small dimensions, must be full and not hollow.
  • figs 1 - 2 represent an elevated view of the frame according to the finding and the profiles of the sections of the frame at, respectively, the upper tube, the bottom bracket shell, the rear forks, the seat tube and the oblique tube.
  • figs 1 - 2 the structure of the bicycle frame consisting of a single tubular body, wholly indicated with reference numeral 100, substantially consists of the following elements:
  • - head tube located in the front part and configured to receive the tube of the rotary fork group and the handlebars, through the bearings;
  • the frame 100 described above consists of a single piece, which comprises a front triangle 101, consisting of the head tube 1, the upper tube 2, the oblique tube 3, the seat tube 4, the bottom bracket shell 5 and a rear triangle 102, consisting of the seat tube 4, the pair of chainstays 6 and the pair of brackets 7 and where said rear triangle 102 is closed at the rear vertex through the forks 8.
  • a frame is made consisting of a single body with tubular section 100, substantially like a "hollow shell", where the carbon fibres, which form the laminate having the thickness of the single parts 1, 2, 3, 4, 6, 7 and of the bottom bracket shell 5, are not interrupted and constitute a single lattice that is configured, at the rear end, in closing plates to form the forks.
  • the specificities of the frame 100 are made very clear from fig. 8 and from the relative sections, from which it is possible to see the tubular structure of the upper tube 2 equipped with the niche 20 (fig. 9), the shaped structure of the base of the bottom bracket 5 (fig. 10), the tubular structure of the bracket 7, which ends with the plate of the fork 8 (fig. 11), the tubular structure of the seat tube 4, equipped with the holes 11 (fig. 12) and the tubular structure of the oblique tube 3, equipped with the niches 20 (fig.13).
  • the process for making the frame according to the finding provides for:
  • the frame according to the finding can also have a configuration that is different from the one described, for example providing for a frame without the upper tube 2 or the bracket 7; moreover, the size and other technical data inherent to the frame itself can vary, provided that it is encompassed by the inventive concept defined by the following claims.
