Two wheel steering scooter with latitudinal aligned wheels

Abstract

A two wheel steering scooter with latitudinal aligned wheels device. A center user support member connects the rear head tube to the front head tube. The rear wheel attaches to the rear fork extending upwards. The rear fork steerer column passes through the rear head tube and can rotate within the rear head tube by means of a bicycle bearing headset. A rear steering handle is connected to the rear fork steerer column. The rear steering handle is designed to contact the user's left hand with arm extended. The front wheel attaches to the front fork extending upwards. The front fork steerer column passes through the front head tube and can rotate within the front head tube by means of a bicycle bearing headset. A front steering handle is connected to the front fork steerer column. The front steering handle is designed to contact the user's right hand with arm extended. The rider's left arm is positioned at the user's left side and contacts the rear steering handle. The rider's right arm is positioned at the user's right side and contacts the front steering handle. The device moves forward to the rider's right. The steering handles should be adjusted so that the rider's body is roughly balanced across the vertical plane of the rear and front wheels. The device moves to the right and the rider keeps the device balanced by constantly correcting the coordinated rear and front steering. It may take some practice to make this correction reflex, but once mastered this device offers more control and artistic expression than a currently available scooter.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to recreational devices like scooters.

BACKGROUND OF THE INVENTION

[0002] The invention relates to scooters and comprises a support frame and two steerable wheels mounted in a latitudinal direction. More specifically, the present invention relates to scooters which can be used to traverse smooth and rough terrain including mountain slopes.

[0003] Human balance can be considered in two separate axes. Human balance left side to right side and human balance front to back. Left to right human balance is relatively inaccurate; as evidenced by trying to stand on one foot. However since the human body has two feet there is a constant correcting mechanism by moving ones hips and upper body relative to both left and right foot. This endless correction makes left to right balance very useful for walking and standing. Left to right human balance is symmetric in that the capabilities to the left are equal to the capabilities to the right. Devices based on human left to right balance, like the scooter tap into this constant correcting mechanism. A scooter is in a constant state of losing its balance and with the endless correcting of the front wheel it is kept in balance. People learn to ride a scooter because this constant correcting is much like the person's natural left to right correction mechanism.

[0004] Front to back balance is in many ways much more accurate as evidenced by the operation of the ankle and foot as you lean slightly forward. There is none of the left to right instability as when you stand on one foot. Front to back balance is not symmetric. Front balance has leverage close to the ground for correcting balance; namely the ankle and foot. Back balance has no equivalent to the ankle and foot and must rely on greater precision and a degree of weight shifting. It is more natural to lean forward protected by the leverage of the foot. Leaning backwards is often a frightening experience.

[0005] Devices that leverage front to back balance include snowboards and to a lesser extent skateboards. In both cases balance is restored by pushing down on ones toes with respect to ones heels or lifting ones toes. This action in a snowboard causes the board to carve into the snow in a forward or rearward direction and thus recovering balance. These actions in a skateboard causes the truck to change the relative orientation of the rear axle with respect to the front axle and turning toward the front or towards the rear and again regaining balance. Snowboards and skateboards traveling at high speed tend to be difficult to control and are better suited to slow speed artistic expression. This is because the length of a person's foot is relatively short when compared with the distance between left and right foot with feet apart.

[0006] Devices that leverage left to right balance include currently available scooters.

[0007] The present invention discloses a two wheel steering scooter with latitudinal aligned wheels. This will leverage human front to back balance primarily with left to right balance having only secondary input. The user stands on the scooter platform and balances the device by continuously correcting the orientation of the left and right wheel with his/her left and right hand respectively. The user's body faces perpendicular to the direction of motion. The left and right steering handles should be adjusted to connect with the user's hands with arms extended and positions the user's body to roughly balance the left to right center axis of the device. The user's left hand grips the left wheel steering handle. The user's right hand grips the right wheel steering handle. When the user feels himself/herself falling forward out of balance, the user moves his/her hands in such a way as to track the device forward of the original line of motion and thus regaining balance. The user must be in a state of constant correction which with practice will become natural and reflex. This device moves the user in a sideways direction. Each handle is equipped with a steering lockout lever that locks that particular steering when the user lets go of the handle. This allows the device to be propelled forward in the same way as a currently available scooter. Once the user has mastered the basics of turning the user can start introducing his/her weight into the turns by leaning into the turns. The feedback from this device is strongest when the user uses his/her weight. This device may not compete with a regular scooter with respect to operation on flat ground. However it is expected that this invention will excel at carving turns and will work best on hills. It is expected that this invention will be more expressive than a regular scooter and will reward the operator with much positive feedback of having mastered his/her balance.
