Definitions

  • This invention relates to a self-supporting motorized cycle, such as a motorcycle, motorbike, motor scooter, or the like. It provides for a "traveling kickstand" which supports the motorized cycle during operational stops avoiding the need for the rider to dismount during such stops .
  • the support includes wheels laterally placed on either side of the cycle which are normally retained in a stored position which is retracted so as not to interfere with the normal operating of the cycle.
  • the support mechanism will be lowered into a supporting position on either side of the cycle.
  • the support wheels on either side will be able to support the torque of the motorized cycle and the driver and will retain the cycle in a substantially upright position during such stop.
  • the support wheels will be retracted to permit the cycle to operate in its normal manner.
  • FIG. 1 is a perspective view of a motorized cycle, in this case a motorcycle, showing the support mechanism connected thereto;
  • FIG. 2 is a view similar to that of FIG 1 but this time showing the support mechanism including a guard cover;
  • FIG. 3 is a side elevational view of the motorized cycle showing the support mechanism in its retracted position
  • FIG. 4 is a side view similar to that of FIG. 3 showing the support mechanism in its lowered position
  • FIG. 5 is a block diagram of the operating system of the present invention
  • FIG. 6 is a schematic perspective view showing the support mechanism as coupled to frame portions of the motorized cycle
  • FIG. 7 is a side view of FIG. 6 and showing the support mechanism in its upright, retracted position
  • FIG. 8 is a view similar to that in FIG. 7 but showing the support mechanism in its lowered operational position
  • FIG. 9 is a sectional view taken along lines 9-9 of FIG. 7;
  • FIG. 10 is a cross-sectional view taken along lines 10-10 of FIG. 8;
  • FIG. 11 is a enlargement of Section C shown in FIG. 9; and FIG. 12 is a side elevational view showing schematically a motor scooter utilizing the support mechanism of the present invention.
  • the motorized cycle typically includes a frame 12, a front wheel mechanism 14, a rear wheel mechanism 16, a seat portion 18, an upper structure 20, and the handlebar mechanism 22.
  • the rear wheel 16 is maintained on a central hub 24.
  • a beam 26 interconnects the frame 12 to the central hub 24 of the rear wheel. Supported on the beam 26 is the support mechanism of the present invention, generally referred to as 30.
  • such support mechanism is shown as including a support frame 32 and wheels 34 and 36 (as shown in FIG. 6) .
  • the wheels are shown as being exposed.
  • the wheels could be covered by a wheel guard 38.
  • a similar wheel guard would be covering the opposite wheel not shown in FIG. 2.
  • the support mechanism 30 when the motorized cycle 10 is in its normal operating condition during driving, the support mechanism 30 is in its upright or retracted position whereby it is removed from the surface contact of the road on which the cycle rides. Thus, it will be out of the way and will not interfere with the normal driving of the motorized cycle.
  • the support mechanism 30 automatically lowers so that the wheels 34, 36 engage the road surface and avoid the need for the driver to lower a foot on one side or the other side. Because of the presence of the wheels laterally on either side of the cycle, the cycle will be self-supporting during the time that it is at a standstill. However, once the cycle starts accelerating again into its normal operating mode, the support mechanism 30 will again move upward into its retracted position, shown in FIG. 3. It should be appreciated that if the guard covers shown in FIG.
  • the guard covers remain in the upward position and need not move up and down.
  • wheels will be necessary.
  • the wheel must be sturdy, lightweight and wear resistant. Inflatable tires are a possibility. Since the wheels are not used for propulsion, and since they must activate only for a relatively short time before coming to a full stop, solid metal wheels with a molded rubber rim are also an option.
  • the best location for the wheels from a balance viewpoint is directly under the seat, near the center of gravity. The farther out to the side that the wheels extend the better, as the weight distribution will fall proportionately.
  • the weight will be distributed between the main wheels of the bike, and the additional support wheel on the side where the rider is leaning, as a direct proportion between the distance of the center of gravity from each element. For instance if the support wheel extends 15 cm and the rider is leaning 1 cm to the right, the right support wheel will carry 1/15 of the total weight of the bike and rider (i.e. by way of example, 30kg for a 450kg total weight) .
  • the main factor that needs to be considered when evaluating the forces involved is the speed at which the wheels be set in place.
  • a rider is constantly maintaining his balance by turning into the direction to which his weight or more exactly the bike and rider's combined center of gravity is leaning.
  • the torque working on the line of contact with the road to topple the rider over is countered by the torque of centrifugal force in the opposite direction.
  • the equation governing the balance is:
  • the mass is not a factor, only speed and the height of the center of gravity. The faster the speed the larger the radius of turn can be when turning into the fall and the farther the rider can swerve left or right off center and still maintain his balance. In other words, the slower the bike is moving, the harder it is to keep balance, the more upright the rider must be and the more the wheel will wobble.
  • a speed sensor 50 is provided for detecting when the speed of the motorized cycle drops below a preset value. That value can be preset for the system but could also allow for modification by the user, if desired.
  • An electric sensor connected to the speedometer serves this purpose. When it detects a drop below the set value it sends a signal to a switch such as a relay 52. The relay closes a circuit that starts the electric motor 54 operating.
  • Electric motor 54 is a bi-directional motor and in this case the switch will cause it to rotate in a first direction, by way of example the clockwise direction.
  • the motor which is fixed to the motorized cycle's frame, turns a powerscrew 56 likewise in the clockwise direction, by way of this example.
  • the powerscrew passes through a threaded nut (to be described later) which is secured to the support wheels 58. As a result, the powerscrew turns in its thread and the support wheels are lowered.
  • the motor must provide enough torque to straighten the bike and support the rider while stationary, but not enough to raise the bike off its tires. Once the motor reaches its stalling torque, it stops turning and control 60 retains the motor such that the support wheels stay lowered. After completing the stopping, whether it be for a red light, traffic, or the like, as the rider accelerates past another preset high speed, the electronic speed sensor 50 detects this and sends a signal to switch relay 52. This time the relay closes a circuit that starts an electric motor rotating in the opposite direction, by way of example counter-clockwise.
  • the support frame 32 containing the wheels 34, 36 uses a powerscrew 56 connected to the motor 54.
  • the structure has a threaded nut 70 fixed to the top so that it turns against the screw and moves the support wheels 34, 36 on the support frame 32 up and down accordingly.
  • An additional guide rod 74 is connected to prevent lateral turning and keep the movement limited to a vertical movement.
  • a shoulder 76 extending around the powerscrew near the motor is permanently fixed, such as by welding or the like, to a thrust bearing 78.
  • the thrust bearing is clamped to the beam 26 which is connected to back tire support 24 and extends from the motorcycle's frame 12.
  • Such coupling could be by means of screws, bolts, or the like.
  • the bike is brought to center equilibrium by direct vertical force against the road. This requires the smallest force and therefore the most compact and efficient actuator motor.
  • the other solutions all involve a parasitic lateral force against the pavement, causing excessive wear and requiring a larger motor. Erosion of the wheels would require regular wheel replacement or high cost material that can withstand wear.
  • a wide wheel base is not necessary. As was shown even a narrow wheel base of 30 cm, 15 cm. on each side easily could handle the force required to raise the bike to center.
