Description

FIELD OF THE INVENTION

[0001] The present invention relates to a scooter which has two reciprocating pedals connected by a wire and drive wheels connected to the pedals.

BACKGROUND OF THE INVENTION

[0002] A conventional and popular scooter is shown in FIG. 7 and generally includes a deck 40 with a rear wheel set 42, and a connection mechanism 44 on a front end of the desk 40. A head tube 45 is connected to the connection mechanism 44 and a handlebar stem 43 is rotatably connected to the head tube 45. A front wheel 41 is connected to a lower end of the handlebar stem 43 and a handlebar is connected to a top end of the handlebar stem 43. The user has to step one foot on the desk 40 and rows the other foot on the ground to move the scooter forward. The foot on the deck 40 often feel exhausted because it has to bear the body and keep balance during moving. Most of the users use a specific foot on the deck 40 so that only one foot is exercised by kicking and pushing against the ground. Some people cannot operate the scooter properly because it requires good balance sense and some people do not prefer to use the scooter because only one leg is exercised.

[0003] The present invention intends to provide a scooter which is driven by two pedals which are operated reciprocally by two feet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0017] Referring to FIGS. 1 to 3, the scooter of the present invention comprises a body 2 having a central frame 200 and a front part 20 and a rear part 201 are respectively connected to the central frame 200. A connection bar 100 is connected to a front end of the central frame 200 and a head tube 10 is connected to the connection bar 100. A handlebar stem 12 rotatably extends through the head tube 10. A front wheel 11 is connected to a lower end of the handlebar stem 12 and a handlebar is connected to a top end of the handlebar stem 12. A rear wheel 13 is connected to the rear part 201.

[0018] Each of the front part 20 and the rear part 200 has two pulleys 21 on two ends thereof and a wire 22 reeves through the pulleys 21 so that the wire 22 encloses a rectangular area. Two long sides of the rectangular area enclosed by the wire 22 is parallel to the central frame 200 which is located between the two long sides of the long sides. Two toothed belts 23 are connected between the front part 20 and the rear part 201, and are respectively located above the wire 22 of the long sides of the rectangular area.

[0019] Two pedals 3 are fixedly connected to the wire 22 and each pedal 3 includes a base 30 and a top part 34 which is mounted on the base 30. Each toothed belt 23 extends between the base 30 and the top part 34. Two sets of wheels 33 are received in the space 31 in each pedal 3 and each set of wheels 33 has a shaft 330, a one-way bearing 332 mounted to each of the shafts 330 and connected to a gear 331 on the shaft 330, and two wheels 333 connected at two ends of each shaft 330. The gears 331 of the two sets of wheels 33 are engaged with the toothed belts 23. Each pedal 3 further has two pressing rollers 341 connected to an under side of each top part 34 so as to press on a top plain surface of each of the toothed belts 23. Four slots 32 are defined through each of the bases 30 so that the wheels 333 extend through the slots 32 and contact the ground. A positioning strip 340 connected to a top of each of the top parts 34.

[0020] Referring to FIGS. 4 to 6, the user may insert his or her feet into the space between the top part 34 and the positioning strip 340 and alternatively and reciprocally moves the two pedals 3. The one-way bearings 331 allow the shaft 330 together with the wheels 333 counter clockwise as shown in FIG. 4 to move the scooter forward, and the pedals 3 are moved rearward, the one-way bearings 331 are rotated independently from the shaft 330. By this operation actions, the two legs of the user are exercised and the scooter can be moved under a stable condition.

[0021] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
