Benefits of technology

[0010] It is an object of this invention to provide drive arrangement for pedalling machines such as stepping machines and vehicles such as scooters that may overcome some of the disadvantages of the prior art or at least provide users with a useful choice.

Problems solved by technology

However, considerable difficulty has been experienced in generating any form of pedal-based system for use in scooters.
Trying to generate sufficient power from a cyclic motion in which the radius of the path of the pedal is small is quite difficult.
It is substantially more difficult when provided on an item having no conventional seat on which a user may reside.
Indeed, to a large extent, cyclic motion of pedals is difficult without a seat and although this may be performed for a short period on bicycles where the craned length is substantially greater, even on bicycles it is difficult to maintain this for long periods of time.

Embodiment Construction

[0047] Referring to the drawings, various embodiments of the invention are described. Throughout the description, reference is made to scooters and bicycles with the majority of the description being given in relation to scooters specifically. It will be appreciated on reading the various embodiments that many aspects described may equally apply to stepping machines and other machines or vehicles and although those described are usually provided as two wheeled vehicles, other wheel or non-wheel arrangements may also apply. For example, the basic scooter can easily be provided with a tandem rear wheel or by connecting the drive wheel to a resistance load without making any departure from the aspects of the invention itself.

[0048] The term scooter is generally used in the specification to describe a usually two wheeled vehicle having a body portion on which a user may stand and an upstanding steering column yet no seat or seat post.

Abstract

This invention relates to a drive mechanism for a scooter or similar vehicle. A pair of opposed rotatable crank arms are mounted to a drive gear on the frame. Each crank arm is attached to a footboard that is itself rotatably mounted to the frame. The footboard is mounted further from the axis of the crank arms than the distance from the axis of the crank arms to the point at which they contact the footboards. Reciprocating downward pressure on each footboard drives rotation of the crank arms which in turn drive a wheel of the vehicle.

Description

FIELD OF THE INVENTION [0001] The present invention relates to pedalling machines, such as scooters, stepping exercise machines and other wheeled machines such as bicycles, tricycles and the like. [0002] This invention also relates to drive arrangements or mechanisms for, in particular, although not necessarily solely, pedalling machines or vehicles similar in form to conventional scooters. The invention may, in some aspects, also apply to bicycles or other similar land-based pedal craft. BACKGROUND TO THE INVENTION [0003] Pedalling machines such as stepper or stepping exercise machines are found in many fitness centres. It is desirable that such stepping exercise machines can be configured to combine in synergy the effects of stepping machines and spinning machines which are generally similar to exercise bicycles. [0004] Vehicles such as scooters have existed for a considerable period of time. Throughout that period, the general form of the scooter varied little from the standard c...
