Definitions

  • the field of the invention is two wheel vehicles, including conventional human-powered pedal bicycles, as well as two wheel vehicles having fuel or electrically powered engines or motors, such as mopeds, motorcycles and scooters.
  • the diamond frame consists of two triangles, a main triangle and a paired rear triangle.
  • the main triangle consists of the head tube, top tube, down tube and seat tube.
  • the rear triangle consists of the seat tube, and paired chain stays and seat stays.
  • the head tube contains the headset which supports the front fork.
  • the invention contemplates a completely different and aesthetic bicycle frame design.
  • Fig. 1 is a side view of bicycle frame of a first embodiment of the invention.
  • Fig. 2 is a side view of a second embodiment.
  • Fig. 3 is a top view of the front fork and/or rear fork of the frame shown in Figs. 1 or 2.
  • Fig. 1 shows a bicycle 10 having an arc frame 12.
  • the arc frame 12 is typically formed from a thin wall hollow tube or extrusion.
  • the arc frame 12 generally has smoothly curving cross section, such as a round, elliptical, or oval cross section. However, in alternative designs, other shapes may also be used, such as square, hexagonal, octagonal, or other polygonal shape.
  • the frame 12 is preferably, but not necessarily symmetrical from side to side and top to bottom.
  • the arch frame 12 has a radius of curvature R which may vary with the size of the intended rider, or the style of the bicycle. For example, R may range from about 50-80 or 60-70 cm.
  • the radius R may also vary in designs where the frame is a segment of an ellipse or oval, rather than a segment of a circle.
  • the frame 12 subsumes an arc of about 120-180 or 130-150 degrees, including the front fork.
  • the front and rear axles are at the same level, and the frame, together with the front fork, subsume an angle of about 180 degrees (a semi-circle).
  • the diameter (or largest principal internal dimension for a polygonal shape) ranges from about 7 to 20 cm.
  • the arc is about 140 degrees, with a 66 cm radius (to the centerline) of a round aluminum tube 10 cm outside diameter and 1.6 mm wall thickness.
  • the front fork 20 is attached to the frame 12 via a pivot joint 22.
  • a handle bar 18 may connect to the front fork 20 through a clearance opening at the front of the frame 12.
  • a front fork turret 80 surrounds the clearance opening.
  • Conventional bicycle or moped components such as a seat 13, front and rear wheels 24 and 34, front and rear axles 26 and 36, brakes, gears, etc. may then be attached to the frame and/or the front fork.
  • a seat tube 14 is connected in a cantilever design adjacent to a center location of the frame 12.
  • a chain ring 64, crank 62 and pedals 60 then drive a chain 66 extending around a rear sprocket 68 to propel the bicycle.
  • the front fork has left and right sides 28 and 30 with the front wheel 24 positioned between them.
  • the back end of the frame 12 is similarly split to accommodate the rear wheel 34 generally on a centerline of the frame 12, between left and right side seat stays, having the same form as the front fork, and designated as 70 and 72 in Fig. 1.
  • the bicycle in Fig. 2 also includes a front shock absorber 102 and rear axle slots 90 for adjustment of the rear axle position.
  • an electric motor 44 and/or an internal combustion engine 46 may be located within the frame 12. If used they can be linked to a sprocket on the rear wheel via a belt or chain extending inside or outside of the frame.
  • Related components such as a battery or a controller 42, or a fuel tank 40 may also be located inside of the frame.
  • One or more access doors 48 may be provided on the frame, to access storage compartments formed within the frame, or to access internal components, such as a motor 44.
  • a motor 44 or 46 may optionally be located elsewhere on the frame 12, such as on the seat tube, with related components such as a controller, battery, fuel tank, etc. located within the frame and connected to the motor via electrical cables and/or fluid lines.
  • Fig. 2 shows an alternative design further including chain stays 50, and a motor 44 or 46 supported on the chain stays 50 and/or the seat tube 14.
  • the frame 12 may also be made of composite materials or plastics materials instead of metal. While a smoothly curving arc provides a unique appearance to the frame, the frame may optionally be made of a large number of tubular segments joined together, as with a polygon having a large number of sides.
  • the seat When the frame 12 is used as a bicycle, the seat may be movable along the frame, and the pedals may be movable on the seat tube, to adjust for riders of varying height. These adjustments may be made repeatedly by the rider, or they may be selected and set at the factory during manufacture of the bicycle.

Abstract

L'invention concerne une bicyclette ou autre véhicule à deux roues comprenant un cadre (12) réalisé sous la forme d'un arc continuellement curviligne. Une fourche avant (20) est attachée de manière pivotante et adjacente à une extrémité avant du cadre, et peut avoir une courbure correspondant à la courbure du cadre. Le cadre peut être réalisé à partir d'un tube creux à paroi mince plié en un arc. De manière typique le cadre a une section transversale ronde, ovale ou elliptique, et peut inclure un arc de 120-180 degrés. Les organes de transmission, telles que des batteries (40), moteurs (44, 46), entre autres, peuvent être installés à l'intérieur du cadre (12).
