- With reference to
FIGS. 3 to 5 for an improved scooter, the scooter comprises: aframe 10, whose front end has afront wheel 11 pivotally connected to the front end through afront fork 111, and whose rear end has arear wheel 12, wherein theframe 10 includes astem 13 connected to an upper end of thefront fork 111 and ahandle 131 connected to an upper end of thestem 13; left andright pedal devices 20 pivotally coupled to both sides of theframe 10 respectively, and eachpedal device 20 having acarrier 201 provided for a user's leg to stand on it, a rotatingbody 202 and aswing body 203 disposed at an end of thecarrier 201, and rotatably and pivotally coupled to atransverse pivot 101 at a front end of theframe 10, such that the integrally combinedcarrier 201 andswing body 203 can perform up, down, front and rear swings; left and rightfirst driving devices 30, corresponding to the left andright pedal devices 20 respectively, and each having afirst driving wheel 301, afirst driving belt 302 and aposition restoring element 303, wherein thefirst driving wheel 301 is similar to a free wheel driven in a single direction and installed onto theframe 10 by apivot 3011, and thefirst driving belt 302 is installed around thefirst driving wheel 301, and an end of thefirst driving belt 302 is fixed to theswing body 203 of thepedal device 20, and another end of thefirst driving belt 302 is pulled to theframe 10 by theposition restoring element 303, such that thecarrier 201 of thepedal device 20 normally has an up-swing force; asecond driving device 40, driven by the left and rightfirst driving devices 30 to drive therear wheel 12 to rotate and roll, and comprising a secondactive driving wheel 401 coaxial with thefirst driving wheel 301 of the left and rightfirst driving devices 30, a secondpassive driving wheel 402 coaxial with therear wheel 12, a driving belt (not shown in the figure) installed around the secondactive driving wheel 401 and the secondpassive driving wheel 402, or at least onemiddle shaft 403 installed at a position of theframe 10 and between the secondactive driving wheel 401 and the secondpassive driving wheel 402, and atransmission wheel middle shaft 403. With the transmission of thedriving belts active driving wheel 401 can be transmitted to the secondpassive driving wheel 402 and therear wheel 12. - In addition, the
first driving wheel 301 of the left and rightfirst driving devices 30 can be installed to anaxle bushing 4011 that is coupled to the secondactive driving wheel 401 of the second driving device (as shown inFIG. 5 ), so that after thepivot 3011 is passed through the axle bushing 4011 and fixed to theframe 10, the left and rightfirst driving wheels 301 can be rotated in a single direction like free wheels, wherein the secondactive driving wheel 401 is driven to rotate if the rotation direction is clockwise, or the secondactive driving wheel 401 is rotated idly if there is no rotation or the rotation direction is counterclockwise. - The
frame 10 with the installedstop body 50 corresponds to the left andright pedal devices 20, such that a position limit effect is provided for the up-swingingcarrier 201. - With reference to
FIG. 6 and the structure of the present invention, therotating body 202 of the left andright pedal devices 20 is rotated freely at thetransverse pivot 101 of theframe 10, so that the integrally combinedcarrier 201 andswing body 203 can perform up, down, front and rear swings. After both ends of thefirst driving belt 302 of the left and rightfirst driving devices 30 installed around thefirst driving wheel 301 are pulled to theposition restoring element 303 and corresponding to theswing body 203 of thepedal device 20, thecarrier 201 can normally have the up-swing force. When use, an operator holds thehandle 131 by both hands to control the driving direction, and stands on the left andright carriers 201 by both legs respectively. With a down-stepping operation, theswing body 203 will pull thefirst driving belt 302 to rotate thefirst driving wheel 301 clockwise. If the leg is lifted, thecarrier 201 will be pulled back to the up-swing position by thefirst driving belt 302 and theposition restoring element 303 automatically to get ready for the next down-stepping operation. Since thefirst driving wheel 301 of thefirst driving device 30 is rotated in a single direction like a free wheel, a motive force will be produced if thefirst driving wheel 301 rotates clockwise, and no motive force will be produced in an idle rotation if the firstdriving wheel 301 rotates counterclockwise. When thecarrier 201 is stepped down, the clockwise-rotatingfirst driving wheel 301 will drive the secondactive driving wheel 401 of thesecond driving device 40 to rotate directly. When thecarrier 201 resumes its up-swing position, thefirst driving belt 302 pulled to restore its position by theposition restoring element 303 will drive thefirst driving wheel 301 to rotate in an opposite direction, and thus resulting in an idle rotation that will not drive the secondactive driving wheel 401 to rotate. Since the secondactive driving wheel 401 of thesecond driving device 40 is driven to rotate, transmission components such as thedriving belts transmission wheels passive driving wheel 402 to rotate therear wheel 12 coaxial with the secondpassive driving wheel 402. With thefront wheel 11, the scooter of the present invention can be glided smoothly. - Since the left and right
first driving wheels 301 are driven to rotate in a single direction like free wheels, a clockwise rotation of the left and rightfirst driving wheels 301 can drive the secondactive driving wheel 401 to rotate, and a counterclockwise rotation of the left and rightfirst driving wheels 301 or maintaining the left and rightfirst driving wheels 301 still will give an idle rotation that provides no motive force. In other words, the left andright carriers 201 can drive thefirst driving wheel 301 to rotate clockwise and also rotate the secondactive driving wheel 401 together with therear wheel 12 to drive the scooter to move forward when the left andright carriers 201 are stepped downward. When the left andright carriers 201 are swung upward, the firstdriving wheel 301 is rotated idly and will not drive the secondactive driving wheel 401. When the left andright carriers 201 remain still, thefirst driving wheel 301 will not interfere with the still condition of the secondactive driving wheel 401. The operator can stand on the left andright carriers 201 by both legs respectively to perform the up and down swing movements to the left andright carriers 201, or step thecarrier 201 to its lowest point by one leg, and step theother carrier 201 by another leg. The scooter of the present invention provides a diversified and convenient operation. - In other words, the aforementioned structure of the present invention allows an operator to hold the
handle 131 by both hands, and stand on the left andright carriers 201 respectively by both legs, such that both legs can apply forces alternatively to step the left andright carriers 201, or step on acorresponding carrier 201 by one leg to apply reciprocal forces to achieve the effect of driving the scooter to move forward. The invention not only complies with the simple, convenient, smooth and diversified ergonomic requirements and provides a unique operation and driving mode, but also achieves the effect of providing a recreational sport with fun. Of course, the operator can operate the scooter by stepping on the carrier(s) by both legs or by one leg according to the road condition to achieve the effect of riding the scooter with a balanced stability, a constant speed and a safe effect.
