Abstract
It is disclosed a vehicle and in particular a scooter in which there is present a fist and a second elements separated from each other and movable relative to a base frame, said elements defining respective actuating surfaces disposed substantially in side by side relationship with each other with respect to a longitudinal extension axis of the vehicle; an alternated operation of the first and second movable elements (6, 7) allows a motio-transmitting unit (8) to convert the reciprocating motion into a rotatory motion imparted to one of the scooter wheels thereby causing advancing of the vehicle. The particular positioning and configuration of the movable elements (6, 7) allows a steady and efficient use of the scooter.

In fact devices having means for motion generation on 5- board are often of uncomfortable use. In fact, in the scooters provided with a driving pedal the same leg is always to be used to supply the required energy for motion.
If the rider is tired to use one foot for driving the scooter, use of. the other foot is substantially impossible; in addition, to enable the scooter to advance to a convenient speed, the pedal must be operated over a long path stretch. This obviously gives rise to an uncomfortable position in.addition to' a considerable effort for operation.
With reference to the above described third type of scooter that is provided with an oscillatable rocking 20.:lever, it is to be pointed out that the particular arrangement of the plate necessarily involves an uncomfortable position for the rider driving the motion-transmitting unit. In fact the user rides the scooter with one foot at a position greatly advanced towards the front wheel and the other foot at a backward position, close to the rear wheel. In addition, the two feet are at different heights so that the rider's comfort is further reduced.
Finally, in order to obtain a good advancing, big travels of the oscillating end portions are required and said portions must have a suitable distance from the fulcrum. For the above reason a rider must alternately move his/her weight backward and forward, Making, into account the fact that the rider's fully

It is also to be pointed out that in the presence of potholes or debris, positioning of the overall (scooter and rider) centre of gravity is. of a fundamental importance to ensure an optimal steadiness and roadholding of the vehicle, which feature is not LO present in the above described scooters.
Accordingly, it is an object of the present invention to substantially solve all the mentioned drawbacks.

- 6 -In more detail, there is also the presence of at least one first and one second movable elements or plates 6,
7; both said elements are movable relative to the base frame 2 and also active on a motion-transmitting unit 8 to enable driving in rotation of at least one of the wheels 3, 4 and consequent motion of the vehicle.
The motion-transmitting unit 8 is associated with the base frame 2 and is also designed to receive motion from said movable elements 6, 7 and transfer it to one of the two wheels 3, 4, the rear wheel 4 for example.
As viewed from Fig. 1, the first and second movable elements 6, 7 possibly are distinct elements separated from each other and they are movable in a reciprocating manner close ,to and away from the base frame 2 (in particular see arrow 9 in Figs. 1, 2 and 4).
Actually, the first and second movable elements 6, 7 define respective actuating surfaces essentially disposed in side by side relationship with respect to a substantially longitudinal extension axis 10 of the vehicle.
In the emlaodiment shown the first and second movable elements 6,.7 are hinged on the base frame 2, at a front region 1a of the vehicle, for example.
Thanks, to this configuration these elements 6, 7 alternately oscillate up and down along direction 9, around a hinging axis 11.
In particular, oscillation takes place between a point of maximum distance from the base frame 2 (or maximum travel; see the first element 6 in the position shown in Fig. 1) and a point of minimum distance from the base frame 2 (or minimum travel; see the second movable element 7 in the condition shown in Fig. 1).
The scooter also comprises synchronisation means 12 capable of suitably coupling the movements of the first and second movable plates 6, 7.
In particular, following a displacement of the first LO plate 6 to the position of maximum distance from the base frame 2, the second movable plate 7 takes a position of minimum distance from frame 2 (configuration shown in Fig. 1); following return of the movable element 6 towards the base frame 2, the second~movable element 7 will reach its position of maximum distance from the frame itself. In other words, to the upward stop limit of one movable element .corresponds the downward stop limit of the other movable element and vice versa.
To allow the' above movements, said synchronisation means 12 comprises a fixed structure 13 emerging away from the base frame 2 and a deformable body 14, preferably a belt, that is movable on the fixed structure 13 and in engagement by its ends with said first and second movable elements ~6~, 7.
Tn detail, there is the presence of a roller 15 idly mounted on the fixed structure 13 and over which belt 14 can run.
Looking - at Fig. 2-, - it is clearly ~ appa-rent how the 'movement synchronisation of the first and second movable elements 6, 7 takes place.
_ g _ In particular a downward displacement of the movable plate 6 along direction 9 involves a rotation of roller 15, the movable element 7 being correspondingly driven upward by belt 14.
In addition, still looking at Figs. 1 and 2, it is possible to see' that the movable elements 6, 7 are defined by elongated plates disposed in mutual side by side relationship along the longitudinal vehicle axis 10.
In particular said plates exactly define the support surfaces designed to receive the rider's respective feet and actually said rider can stand on the scooter 1,5 keeping his/her legs and feet close to each other in side by side relationship, that is in a substantially steady and comfortable position.
The motion-transmitting unit 8 is now examined. It is to be pointed out first of all that it is able to convert the reciprocating motion of the movable plates 6, 7 into a rotatory motion applied to the second wheel 4.
To enable this conversion~the motion-transmitting unit
The motion-transmitting unit 8 is associated with the base frame 2 and is also designed to receive motion from said movable elements 6, 7 and transfer it to one of the two wheels 3, 4, the rear wheel 4 for example.
As viewed from Fig. 1, the first and second movable elements 6, 7 possibly are distinct elements separated from each other and they are movable in a reciprocating manner close ,to and away from the base frame 2 (in particular see arrow 9 in Figs. 1, 2 and 4).

Thanks, to this configuration these elements 6, 7 alternately oscillate up and down along direction 9, around a hinging axis 11.
In particular, oscillation takes place between a point of maximum distance from the base frame 2 (or maximum travel; see the first element 6 in the position shown in Fig. 1) and a point of minimum distance from the base frame 2 (or minimum travel; see the second movable element 7 in the condition shown in Fig. 1).
The scooter also comprises synchronisation means 12 capable of suitably coupling the movements of the first and second movable plates 6, 7.
In particular, following a displacement of the first LO plate 6 to the position of maximum distance from the base frame 2, the second movable plate 7 takes a position of minimum distance from frame 2 (configuration shown in Fig. 1); following return of the movable element 6 towards the base frame 2, the second~movable element 7 will reach its position of maximum distance from the frame itself. In other words, to the upward stop limit of one movable element .corresponds the downward stop limit of the other movable element and vice versa.
To allow the' above movements, said synchronisation means 12 comprises a fixed structure 13 emerging away from the base frame 2 and a deformable body 14, preferably a belt, that is movable on the fixed structure 13 and in engagement by its ends with said first and second movable elements ~6~, 7.

The motion-transmitting unit 8 is now examined. It is to be pointed out first of all that it is able to convert the reciprocating motion of the movable plates 6, 7 into a rotatory motion applied to the second wheel 4.
To enable this conversion~the motion-transmitting unit
8 first. of all comprises at least one deformable element 16 that can be for example a belt, a chain, or other similar element directly in engagement. (see .,reference 17 in Fig. 4) with the first and second movable elements 6, 7 and also active at a rotation axis 18 of the second wheel 4.

- 9 -frame 21 and allow a sliding movement of the deformable element 16 over them, as better specified in the following.
The motion-transmitting unit 8 is also equipped with two further free wheels 20, 21 preferably fitted on the axis 18 of the second wheel 4 to. transfer the motion received through the ~ deformable element 16 to the second wheel 4 in an alternated manner.
In detail ~as regards construction, there will be the presence of at least one and preferably two intermediate members 19 for each movable element 6, 7 and at least one and preferably two intermediate members 19 for each side (corresponding to each movable element 6, 7) disposed on the base frame 2 (see the right-hand frame half shown in Figs. 4 and 5).
Finally, the motion-transmitting unit 8 comprises a further intermediate member 22 (shown in Figs. 4 and 5) that is disposed horizontally to allow motion of the deformable element 16 between the first and second movable elements 6, 7.
25~ after the above statements from a structural point of view,'operation of the vehicle in accordance with the invention is as follows.
The rider gets ~on the scooter placing one foot on the movable plate 6 and the other foot on the movable plate 7 ~ in side by side relationship and close to the rear region ~of the scooter--itself.
Then the rider starts moving his/her weight on the left leg and right leg in an alternated manner so as to
The motion-transmitting unit 8 is also equipped with two further free wheels 20, 21 preferably fitted on the axis 18 of the second wheel 4 to. transfer the motion received through the ~ deformable element 16 to the second wheel 4 in an alternated manner.
In detail ~as regards construction, there will be the presence of at least one and preferably two intermediate members 19 for each movable element 6, 7 and at least one and preferably two intermediate members 19 for each side (corresponding to each movable element 6, 7) disposed on the base frame 2 (see the right-hand frame half shown in Figs. 4 and 5).
Finally, the motion-transmitting unit 8 comprises a further intermediate member 22 (shown in Figs. 4 and 5) that is disposed horizontally to allow motion of the deformable element 16 between the first and second movable elements 6, 7.
25~ after the above statements from a structural point of view,'operation of the vehicle in accordance with the invention is as follows.
The rider gets ~on the scooter placing one foot on the movable plate 6 and the other foot on the movable plate 7 ~ in side by side relationship and close to the rear region ~of the scooter--itself.
Then the rider starts moving his/her weight on the left leg and right leg in an alternated manner so as to
- 10 -impart an alternated oscillatory motion to plates 6, 7 around the hinging axis 11.
Correspondingly, through the synchronisation means 12, motion of plates 6, 7 is maintained synchronised 'because belt 14 allows a downward motion of a first one of said plates simultaneously with an upward motion of the other plate and vice versa.
During this reciprocating motion, and in particular during the upward motion, illustrated in the passage of configuration from Fig. 5 to Fig. 4 for example, the deformable element 16 linked to the fixed frame at points 17 is submitted to a dragging action and passes from a configuration of minimum extension shown in Fig.
5 to a configuration of maximum extension shown in Fig.
4.
In particular moving of the intermediate members 19 present on the first movable plate 6 away from those 'present on the fixed frame 2 involves creation of respective.U-shaped undulations of a higher length that therefore give rise to a displacement of belt 16 away from the horizontal intermediate member 22 towards the first free wheel 20 so as to reach the configuration shown in Fig. 4.
During this movement therefore the belt 16 drives the free wheel 20 in~rotation, which wheel in turn, being fitted on the shaft of wheel 18, gives rise to a corresponding rotation of the latter that is converted into-an advancing movement of the-scooter.

First of all the present invention, depending on requirements, allows use as a scooter to be pushed in a traditional manner for example at the starting moment and to be pushed by means' of levers in order to maintain or increase speed.
The vehicle allows speeds comparable with those of a normal bicycle to be maintained for a long period of time under conditions of great steadiness of the vehicle in use.
The particular positioning of the movable plates .enables the rider to maintain a correct position on the -scooter and also to drive it in a comfortable manner and with a reduced effort.
In fact, due to the presence of two movable levers, the necessary travels to ensure an optimal advancing of the vehicle can be halved; selecting an upward end-of-stroke position the travel of which is not very long allows the rider's effort to be minimised; in fact the rider is able to drive the device of the invention by lateral displacements of his/her weight and small variations in the height of his/her legs and feet.
Finally the rider can maintain his/her rest position by lying both feet on the two plates keeping the latter to 'the same height, which further increases comfort in use.
In particular, by adopting two separated pushing plates distinct from each other the--r-ider'-s movements are made easier and the foot-rest surfaces are disposed much closer to each other.
Correspondingly, through the synchronisation means 12, motion of plates 6, 7 is maintained synchronised 'because belt 14 allows a downward motion of a first one of said plates simultaneously with an upward motion of the other plate and vice versa.
During this reciprocating motion, and in particular during the upward motion, illustrated in the passage of configuration from Fig. 5 to Fig. 4 for example, the deformable element 16 linked to the fixed frame at points 17 is submitted to a dragging action and passes from a configuration of minimum extension shown in Fig.
5 to a configuration of maximum extension shown in Fig.
4.
In particular moving of the intermediate members 19 present on the first movable plate 6 away from those 'present on the fixed frame 2 involves creation of respective.U-shaped undulations of a higher length that therefore give rise to a displacement of belt 16 away from the horizontal intermediate member 22 towards the first free wheel 20 so as to reach the configuration shown in Fig. 4.
During this movement therefore the belt 16 drives the free wheel 20 in~rotation, which wheel in turn, being fitted on the shaft of wheel 18, gives rise to a corresponding rotation of the latter that is converted into-an advancing movement of the-scooter.
