  • cambering vehicles are commonly three wheeled vehicles. They may have a front column with a steering shaft and a front wheel attached thereto, and a pair of spaced apart rear wheels, each rear wheel mounted to trailing arms which are articulated to the front column. The rider of such vehicles 15 would place each foot on foot supports located on the articulating railing arms and hold a pair of handlebars which extend from the steering shaft. US patents 6880840 and 6883814 describe such a device.

  • Such cambering mechanisms typically suffer the disadvantage that at any angle of camber each foot support will be unhelpfully sloping downwards and/or upwards in relation to the ground and the other vehicle parts. Therefore, such vehicles may require a shift of 25. balance by the rider in order to achieve a cambering or canting effect.

  • the present invention could be described as a cambering tricycle apparatus 1 that employs vertically suspended, rearwardly sweeping linkage arms 23 and 25 that pivot rearwards as a result of the user's leg movements. This action produces leveraged cambering over of the apparatus 1 without the user having to shift his or her centre gravity.
  • the parallelogram configuration of the linage arms 23 and 25 in combination with the foot rests 20 enable the foot rests 20 be maintained in a parallel orientation with respect to die ground even if the user and apparatus 1 are cambered over steeply.
  • the apparatus 1 and user can be supported at the lean over limit by the trailing rear wheels 21.
  • Such arrangements offer the degree of necessary control to safely operate a high speed and sharp cornering apparatus 1.
  • An aspect of the present invention is that every part of the apparatus 1 can be induced to camber steeply in both left and right directions as a result of the user pushing backwardly on one of the foot rests 20 while maintaining the opposite foot rest in a forwards position (i.e such that linkage arm 25 is substantially vertical).
  • the biasing members 30 for urging the linkage arms (and thus foot rest 20) to their forward position provides for rapid reversal of camber or the resumption of an upright stance.
  • cambering the apparatus 1 The work that a user applies in cambering the apparatus 1 is directed lengthwise relative to the direction of the apparatus in general.
  • the forces applied rearwardly to the foot rests 20 by the users feet to initiate cambering of the apparatus are therefore applied at right angles to the desired direction of camber. Because of this the camber forces applied to the foot rests 20 generates only minimal steering interference.
  • biasing members 30 also are tensioned in a lengthwise direction relative to the direction of the apparatus 1 in general so that steering will be unaffected by their tension.
  • the tension of the biasing members 30 against the user's foot pushing backwardly on the foot rests 20 should be reasonably constant at all points in the arc of travel of the foot rests 20.
  • the front wheel 4 may be larger than the two trailing wheels 21. In the preferred embodiment, the diameter of the front wheel 4 is approximately twice the diameter of the rear wheels 21.
  • a standard bicycle wheel and associated forks 10 and handlebars 3 can be used with the apparatus of the present invention. This means that parts may be easily obtained from bicycle parts suppliers in order to manufacture the apparatus of the present invention. Also, the comparable small size of the rear wheels 21 ameliorates the problem that large rear wheels would be ineffective in arcing rearwardly quickly to induce a cambering effect of the apparatus 1. Furthermore, a footrest 20 mounted above the axle of large rear wheels would be unacceptably high above the ground, and safety may be an issue.
  • an electric motor may be provided to power the apparatus 1.
  • a hub-mounted electric motor 40 is provided on the front wheel 4.
  • a power source such as a battery pack 41 may be located at some position on the frame 2. The electric motor may therefore allow the apparatus 1 to travel along flat or inclined surfaces without the user being required to
  • the electric motor 40 need not be employed. Any motor and power source may be used with the apparatus of the present invention.
  • the apparatus is configured so as to be safe from a flipping over forwardly because of the size of the front wheel 4. Furthermore, a skilled user should have available leverage with which to actively resist toppling the apparatus himself over sideways.
  • a rigid arm 45 projects rearwards and at a downward angle from the rear of the frame 2.
  • the arm 45 preferably terminates at a set height above the ground so that if the apparatus 1 rears backwards to a dangerously steep angle the distal end of the arm 45 makes ground contact.
  • a rubber tip 46 is placed on the distal end of the arm 45 to improve safety and to maximise its braking friction with the ground surface.
  • a conventional bicycle front wheel brake may be provided for the front wheel 4. Such a brake would normally be sufficient for stopping the apparatus 1 on moderately level ground.
  • the apparatus's front wheel 4 may judder or slide sideways and its braking ability may be reduced.
  • Relatively wide profile tyres are preferred for the rear wheels 21. This is partly for the reason that such rear wheels 21 are then available to provide for efficient rear wheel braking. When both rear wheels 21 are braked evenly together the apparatus 1 will stop without any steering bias.
  • the preferred arrangement is for the rear wheels to be brakeable independently of each other. A desirable effect is to initiate a turn in the direction of the braked rear wheel 21.
  • the combination of the front steering wheel, cambering of die apparatus 1 and braked rear wheel 21 may generate "slides" on low grip surfaces.
  • Braking to the rear wheels 21 can be achieved through foot actuated braking friction against the rear wheels.
  • the user may angle their foot onto the rear wheel to create a braking force on the rear wheel 21.
  • This preferred method for rear wheel braking involves direct contact between the rider's boot or shoe soles and the inside walls of the tyres.
  • Upwardly and outwardly projecting ramps 50 are preferably mounted at suitable locations on the foot support 20 so that the insteps of the user's feet can comfortably straddle the ramps 50.
  • the upward projecting angle of the ramp 50 may assist in preventing the user's foot from being dragged into the space between the ramp 50 and the inside wall of the wheel 21.
  • the ramps 50 are well situated for the user's foot to push against in the action of swinging the foot rests rearwardly to induce a cambering effect on the apparatus 1. This is advantageous because good grip contributes to the riders comfort and safety.
  • the user can actuate the left and right rear wheel brakes independently.
  • Gravity powered sports such as snow skiing might lack mass appeal if people could not be quickly carried back to the top of the slope. Such might be the case with the present invention.
  • Any suitable mechanism to connect the apparatus to a vehicle or other towing device is also anticipated.
  • the apparatus of the present invention may enable a rider to zig-zag across, down and possibly up steep slopes in a similar way to snow skiing.
  • the apparatus can turn tighter and develop higher G forces that a conventional bicycle or tricycle.
  • the apparatus 1 of the present invention can be leaned or cambered merely by coordinating pressures from the feet of a user.
  • the stand up riding position feels may be more desirable and dynamic than sitting or crouching on a bike.
  • the user's feet are on balanced and predictable foot rests.
