Definitions

  • Such frames are used for both road bikes and mountain bikes
  • the terrain that a bike is used on dictates the load requirements for the bike and the performance characte ⁇ stics of the components
  • mountain bikes are used on rough terrain and often are ⁇ dden over roots and jumps they must be more durable than road bikes w hich encounter relativ ely smooth surfaces
  • the seat stay tubes define a gap distance bet een the inner surface of the seat stav tubes at a tire intersection point that at a minimum is greater than about 2 inches
  • the seat stay tubes also hav e a modulus of elasticity value and a moment of inertia value such that the modulus of elasticity value multiplied times the moment of inertia value is between about 1 0 lbxinches" and about 10 lb x ⁇ nches :
  • Figs 1 and 2 illustrate bicycle frame 10 in accordance with the present invention
  • the bicycle frame 10 is a "diamond" type frame and includes a head tube 12. a top tube 14, a down tube 16, a seat tube 18, and a rear angle assembly 20
  • the head tube 12 is generally v e ⁇ ical
  • the top tube 14 extends rearwardly from the top of the head tube 12 and ends at a first portion on the seat tube 18 In this embodiment, the first position is near the upper end of the tube howev er the first portion can be elsewhere such as centrally disposed on the seat tube
  • each seat stay tube 32 or 34 converge toward one another from the dropouts 28 and 30 to the seat tube 18
  • Each seat stay tube 32 or 34 is formed of two sections 32a-b or 34a-b. respectively
  • the first section 32a or 34a is closest to the seat tube 18 and the second section 32b or 34b is closest to the dropouts 28 and 30
  • the first and second sections 32a and 32b are disposed at an angle to one another
  • the first and second sections 34a and 34b are also disposed at an angle to one another
  • the second sections 32b and 34b are curved
  • each annular seat stay tube 32 and 34 has a diameter represented by the arrows labeled d v
  • Each oval chain stay tube 38 and 40 has diameters represented by the arrows labeled d. i and dc : (as shown in Figs. 3 and 3B).
  • the seat tube 18 accepts seat 1 12 mounted on a standard seat post 1 14, and the bottom bracket 22 accepts a pedal assembly 1 15 that includes a crankset.
  • a front brake assembly (not shown), gears and shifters 116a and b, and chain 1 17 are also used with the bicycle. These components are known in the art.
  • the bicycle 100 further includes a rear wheel 1 18 whose axle 120 is supported by the dropouts 30 and 28 (shown in Fig. 3).

Abstract

L'invention concerne un cadre de bicyclette de montagne (10) destiné à être utilisé avec une roue arrière (118). Ce cadre, à forme en 'diamant', comprend des haubans (32, 34) espacés pour définir un intervalle (C) entre leur surface interne (32, 34) à un point d'intersection avec le pneu, au minimum supérieur à environ 2 pouces. Par ailleurs, les haubans (32, 34) ont une valeur de produit entre le module d'élasticité et le moment d'inertie se situant entre environ 1,0 lb x 2 pouces et environ 10 lb x 2 pouces. Le cadre est destiné à être utilisé seulement avec un frein à disque à l'arrière monté sur l'un des haubans (32, 34).
