BICYCLE FRAME

Abstract: The present invention is directed to a mountain bike frame (10) for use with a rear wheel (118). The frame is a "diamond-type" frame that includes seat stay tubes (32, 34). The seat stay tubes (32, 34) are spaced apart to define a gap distance (C) between the inner surface of the seat stay tubes (32, 34) at a tire intersection point that at a minimum is greater than about 2 inches. In addition, the seat stay tubes (32, 34) have a modulus of elasticity value multiplied times the moment of inertia value is between about 1.0 1bxinches<2> and about 10 1bxinches<2>. The frame is for use with only a rear disc brake mounted to one of the seat stay tubes (32, 34).

Description: BICYCLE FRAME TECHNICAL FIELD OF THE INVENTION This invention relates generally to frames for bicycles More particularly, the invention is directed to a mountain bicycle frame BACKGROUND OF THE INVENTION Con\ entιonal bicvcle frames use tubes joined into closed frameworks to interconnect the components (front fork/handlebar assembly, seat, crankset, rear wheel) and transmit the loads there between The tubes also keep the components in spacial relation, l e , they maintain the components relative proximity The traditional bicycle frame includes a top tube, a relatively short head tube, a seat tube, a down tube, a bottom bracket, a pair of chain stavs, a pair of dropouts, and a pair of seat stavs The top tube connects at its front end to the top of the head tube, and extends backw ard to the top of the seat tube The down tube connects at the front end to the bottom of the head tube and extends downwardly and rearwardly to the bottom bracket where the seat tube and the down tube are connected The pair of chain stays extend rear ardly from the bottom of the seat tube to the dropouts The pair of seat stays connect directly or indirectly to the top of the seat tube The seat stays extend backward from the seat tube to the dropouts The seat stays generally include two seat stay tubes that converge from the dropouts toward the seat tube The dropouts support the rear wheel axle This conventional frame design is called the "diamond" frame, because when viewed from the side, the top tube, down tube, chain stays, and seat stays enclose a diamond-shaped space 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 characteπstics of the components For example, since mountain bikes are used on rough terrain and often are πdden over roots and jumps they must be more durable than road bikes w hich encounter relativ ely smooth surfaces With respect to performance characteπstics. due to the riding conditions encountered on mountain bikes, mountain bike brakes must prov ide more braking force than road bike brakes To that end, mountain bikes are typically equipped with cantilever brakes In order to mount cantilever brakes for use on a rear wheel, the seat stay tubes must include brake bosses The brake bosses extend generally perpendicular to the seat stay tubes Cantilever brakes include two separate brake arms that are pivotally mounted on the brake bosses A cable hnks the arms to a brake lev er mounted on the handlebars The other end of each arm has a pad mounted thereto When the lev er is depressed, the cable causes the upper end of each arm to move outward Consequentlv, the lower end of each arm and the pads connected thereto mo e inw ard and contact opposite sides of the πm of the rear heel Cantilever brakes apply a large braking force to the πm Moreover, cantilever brakes exert large lateral forces on the seat stavs. w hich has a tendency to separate the seat stays from one another In order for the seat stays to endure these forces and to minimize the tendencv for the seat stays to spread, thev must meet certain stiffness requirements The stiffness requirements ha e been met bv bending the seat stay tubes into rious geometries, providing large diameter seat stay tubes, providing tubes w ith increased wall thicknesses, and/or using materials that exhibit increased stiffness These techniques can be used separately or in different combinations Howev er, these techniques can add weight to the frame, which is undesirable Some mountain bikes today are equipped for use with cantilever brakes or disc brakes The seat stays for such frames are robust enough to ithstand use ith cantilev er brakes, and the seat stays hav e bosses for receiving cantilever brakes Thus, the techniques mentioned above are used to ensure that the seat stays are stiff enough for use with the cantilever brakes Road bikes, on the other hand, typically use caliper brakes In order to mount cahper brakes to a frame, the seat stays generally include a seat stay bπdge that extends between each of the seat stay tubes The bπdge has a bore defined therein for pivotally mounting the cahper brakes The ca per brakes apply less braking force than cantilever or disc brakes and require less robust seat stays Thus, the seat stays for road bikes are usually less stiff and lighter than mountain bikes The need exists for a lighter weight mountain bike frame that meets the performance characteπstics for mountain bikes SUMMARY OF

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). Referπng to Figs. 3 and 3A. each seat stay tube 32 and 34 is a hollow tube having a center Cs. An outer radius of each seat stay tube is defined by the arrows Ro .. An inner radius of each seat stay tube is defined by the arrows Ris. A wall thickness is equal to the outer radius Ros minus the inner radius R S and defined by the arrows Tb. Referring to Figs. 2. 3 and 3B. each chain stay tube 38 and 40 is a hollow tube having a center Cc. The chain stay tube is oval and references two axii Al and A2 that are perpendicular to one another and the longitudinal axis L of the frame. The first axis Al extends vertically and the second axis A2 extends laterally. The chain stay tube diameter dci is defined parallel to the axis A l . The chain stay tube diameter dc : is defined parallel to A first outer radius of each chain stay tube is defined by the arrows Ro i and is parallel to the axis Al . A first inner radius of each chain stay tube is defined by the arrows Ric: and is parallel to the axis Al .

The components of the frame are formed of aluminum and joined together by conventional techniques such as welding, soldering, brazing fusing, and the like, as known by those of ordinary skill in the art. The recommended material is aluminum 6061 -T6, which is commercially available from various manufacturers. However, other aluminum materials can also be used. Using the recommended aluminum and frame configuration, the diameter of the seat stay tubes ds is less than both of the diameters of the chain stay tubes dα and dc:. Most preferably, the diameter of the seat stay tubes ds is 0.625 inches. If another material is used, the diameters of the tubes may be modified. For example, titanium, steel, metal alloys, composite materials, such as carbon, or the like can be used. The bending stiffness or moment of Inertia (I) in inches 4 for the seat stay tubes which have an annular cross-section is calculated using the equation. π r 4 4 I = τ 4 [ d so ~ d sι where, d o = outer diameter of seat stay; and d = inner diameter of seat stay The modulus of elasticity value (E) for the recommended aluminum is 10. IE 6 psi that forms the inventive frame Other mateπals have different modulii of elasticity values. Referπng to Table I, the moment of inertia value of the seat stay tubes is compared for vaπous frames. The frame of Example 1 is a conventional mountain bike frame with seat stay tubes having a diameter of 0 875 inches and a wall thickness of 0 049 inches The frame of Example 2 is the inventive mountain bike frame with seat stay tubes having a diameter of 0.625 inches and a wall thickness of 0.028 inches. TABLE I Seat Stay Tube Characteristics For Aluminum Frames The conventional frame of Example 1 in compaπson to the inventive frame of Example 2 having the seat stays as discussed above has an El value substantially greater than the El alue of the inventive frame. Thus, El value accounts for the diameter of the seat stay tubes and the mateπal of which it is formed. For the inventive frame, the recommended El value is between about 1 lbxinches 2 and about 10 lbxinches 2 . More preferably, the El value is between about 1 lb χ inches and about 5 lb χ inches 2 . Still more preferably, the El value is about 2 lb χ inches 2 and most preferably the El value is about 2.2 lb χ inches 2 . Other materials and diameters can be combined so that the frame exhibits the El value that falls within the above range is used in the inventive frame. It is preferred that the inventive frame has a moment of inertia value determined using the diameters in Table I. The inventive frame weighs substantially less than the conventional frame. A significant weight savings of about 120 grams for a frame weighing about 1600 grams is achieved. As shown in Fig. 4, a bicycle 100 includes the inventive frame 10. The bicycle includes components that are available in the industry, but the components do not constitute part of the invention. For example, the head tube 12 has a suspension system 102 mounted therein. One end of the suspension system 102 has the handlebars 104 connected thereto, and the other end has front fork 106 extending outwardly and downwardly therefrom. The front fork 106 has the front wheel axle 108 secured thereto for rotatablv supporting a front wheel 1 10. 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). The bicycle 100 also includes a disc brake assembly 122. The disc brake assembly 122 includes a disc rotor 124, a brake lever 125, a caliper 126, and a fluid line 128. The disc rotor 124 is fixedly secured to the rear axle 120 so that when the rear wheel 1 18 and the rotor rotate 124 together. The brake lever 125 is mounted on the handle bars 104. The caliper 126 is mounted on the dropout 30 using the bosses 33 and bores 33a (as shown in Fig. 1). The caliper 126 further includes two opposing, movable pistons (not shown) that when mounted are on opposite sides of the rotor 124. The fluid line 128 connects the lever 125 to one end of the pistons in the caliper 126. The fluid line contains a flowable hydraulic fluid. The other end of the pistons has pads (not shown) mounted thereon. When the lever 125 is actuated, the fluid within the line 128 moves and causes the caliper 126 pistons to move the pads against the rotor 124 in pincer-like fashion to apply a braking force to the rotor 124. When the lever 125 is released, the fluid within the line 128 moves and causes the piston to fully retract the pads to end the braking force on the rotor.
