Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates generally to scooters, and more particularly, to pedal scooters for kids, adults, and physically challenged people who enjoy riding scooter for fun and exercise. 
       BACKGROUND OF THE INVENTION 
       [0002]    Riding for fun and exercise is very popular among individuals of all ages and disabilities. To make the riding easy, safe, and more enjoyable among kids, adults, and physically challenged people, a wide variety of fuel-less riding systems, such as, scooters, bicycles, are suggested in the prior art. In recent years, scooter riding is one of the biggest fads among riding enthusiasts. Scooters appeal to both adults and children for their fun use and ability to be used as legitimate transport. However, one of the problems associated with one type of scooters is that the user must stand at all times and propel the unit with a foot. This can be tiring for the ride and can also cause user to become off-balance while riding. Typically, scooters are ridden by a single person at a time and cannot be used by two persons at once. Further, with the rise in consumer affluence, consumers are willing to pay a little more for the convenience, appearance, and dependability. But, the conventional riding systems neither appeal nor are convenient for portability and packaging purposes. Furthermore, the conventional riding systems are heavy, complex in use, and non-durable for years of effective use. 
         [0003]    U.S. Pat. No. 4,852,898 teaches improvement in a pedal-operated polycycle including a hydraulic cylinder in fluid; pressure integral communication with piston means depending from such pedals; a hydraulic line in substantial co-alignment with the mainframe of the polycycle; an input of the hydraulic line being in communication with the hydraulic cylinder; and a rear wheel drive secured in rotational relationship with both an output of the hydraulic line and a tangent surface of the rear wheel of the polycycle. Riding is can be tiring for the ride and can also cause user to become off-balance while riding. The typical scooters are ride by a single person at a time and can not be used by two persons at once. This system is heavy, non-portable, and complex. It can not be used by two persons at once. Further it does not enable the user to ride in a standard manner and then switch to a seated riding style when desired. 
         [0004]    U.S. Pat. No. 6,375,208 provides a combined skateboard scooter comprising a handlebar, a front body, a transmission device, a wheel device, and a board. A rear end of the front body is pivoted to the board and includes a slot through which a steering rod extends. The steering rod is attached to the handlebar to move therewith and movable along the slot. The transmission device is engaged with the steering rod and the wheel device such that back and forth movement of the steering rod urges the wheel device to move forward via transmission by the transmission device. The wheel device includes wheels attached to front and rear ends of the board. The user may stand on the board and operate the handlebar and the steering rod to move back and forth to thereby move the combined skateboard scooter forward. This system is heavy, not portable, and complex. It can not be used by two persons at once. Additionally, this can be tiring for the ride and can also cause the rider to become off-balance while riding. 
         [0005]    U.S. Pat. No. 6,769,706 teaches a scooter having a steerable front wheel assembly, a rear wheel assembly and a frame linking the front and rear wheel assemblies. The scooter has a drive mechanism comprising front and back crankshafts rotatably attached to the frame and attached to left and right pedals. The front crankshaft transmits power to the rear wheel by means of a front sprocket gear, a continuous chain and a rear sprocket gear. This system is also complex. It can not be used by two persons at once. This can be tiring for the ride and can also cause rider to become off-balance while riding. 
         [0006]    None of the prior arts particularly discuss a system that can be used by two persons at the same time, while making the riding ideal among individuals of all ages and disabilities. The conventional riding systems neither appeal nor are portable. Furthermore, the conventional riding systems are heavy, complex in use, non-durable for years of effective use. 
         [0007]    Accordingly, there is a need for a lightweight, simple in use and durable riding system that can be used by two persons at the same time, while also providing easy, safe, and more enjoyable riding to kids, adults, and physically challenged people.

         [0030]    The steering arrangement is mounted on the front portion  110  of the platform  100 . The steering arrangement comprises a vertical pole  400 , a handlebar  410 , a hinge  420  and a hinge support  430 . The vertical pole  400  comprising a steer bar.  440 , and a steer bar enclosure  450 , is configured to provide an adjustable height varying feature. The steer bar  440  and the steer bar enclosure  450  are coupled to each other in a manner, such that, the steer bar  440  and the steer bar enclosure  450  are arranged telescopically, enabling the steer bar  440  to slidably move within the steer bar enclosure  450 , thereby providing adjustable height varying feature to the vertical pole  400 . The steer bar  440  and the steer bar enclosure  450  are coupled using fasteners  460 , such as, screws, bolts, nuts, and the like. The adjustable height varying feature of the vertical pole  400  enables riders of different height groups to drive the pedal scooter  1000  in a comfortable manner. 
         [0031]    The steer bar enclosure  450  is connected to hinge  420  mounted on the front portion  110  of the top surface  130  of the platform  100  through a hinge support  430 . The hinge support  430  enables the vertical pole  400  to move forward and backward at different positions along a length of the platform and perpendicular to a longitudinal axis of the hinge support  430 , thereby allowing the rider to pull back the handle bar  410  while seated on the seat  300  and steer the pedal scooter  1000 . The forward and backward positions of the vertical pole  400  is controlled using a locking mechanism (not shown) enabling the vertical pole  400  to have different fixed positions with respect to the platform  100 . 
         [0032]    Additionally, the handle bar  410  is equipped with hand grips  470  at two ends of the handle bar  410 . Hand grips  470  provides proper grip to the rider while holding the handle bar  410 , such that, the steering of the pedal scooter  1000  may be achieved by guiding the handle bar  410  in a desired direction of traveling. 
         [0033]    In one embodiment, the braking arrangement includes hand brake  500 , a brake cable  510  and braking calipers  520  (See  FIGS. 1 and 3 ). The hand brake  500  is coupled to the handle bar  410 . At one end, the brake cable  510  connects the hand brake  500  and travels along the vertical pole  400  and over the bottom surface  140  of the platform  100 , such that, the brake cable  510  is secured along the vertical pole  400  and the bottom surface  140  of the platform  100  using suitable securing means such as clips, clamps, and the like. At the other end, the brake cable  510  connects the braking calipers  520 . When the rider applies the brake by pulling the hand brake  500 , the brake cable  510  attached to the hand brake  500  gets stretched, such that, the braking calipers  520  engages with at least one of the wheels thereby causing the pedal scooter  1000  to decelerate. In an embodiment, the braking calipers  520  engage with one of the rear wheels  210 . 
         [0034]    As shown in  FIGS. 4 ,  5 A through to  5 C, illustrated is the drive mechanism. The drive mechanism comprises a pedal  600 , a front sprocket  610 , a rear sprocket  620 , a transmission member  630 , a link  640 , a compressible member  650 , and an opening  660 . The front sprocket  610  and the rear sprocket  620  are coupled with the transmission member  630 , such as, chain, and the like. The front sprocket  610  is connected to the bottom surface  140  of the platform  100  by means of a sprocket connector  670 . The sprocket connector  670  has a small cylindrical projected portion (not shown) wherein roller bearings  680  of the front sprocket  610  are fixed, thereby allowing the front sprocket  610  to rotate about the axis of the roller bearing  680 . The rear sprocket  620  is coupled with the rear axle  230 , and further connected with the bottom surface  140  of the platform  100  by means of sprocket connector  670 . Additionally, the link  640  is coupled at a first end to a side surface of the front sprocket  610  and at a second end to a bottom surface  602  of the pedal  600 , such that, an application of pressure on the pedal  600 , causes the link  640  to move downwards and the front sprocket  610  to rotate in a counter clockwise direction. The link  640  is positioned at an angle inclined towards the seating arrangement of the pedal scooter  1000  and additionally, the pedal  600  is inclined towards the seating arrangement of the pedal scooter  1000 . The opening  660  disposed on the platform  100  enables the link  640  to slide along the opening  660  and along the length of the platform  100 . In one embodiment, the compressible member  650  includes spring, disposed on a top surface  130  of the platform  100 , such that, the link  640  runs through a length of the compressible member  650  and the compressible member  650  is disposed between the bottom surface  602  of the pedal  600  and the top surface  130  of the platform  100 . Additionally, the diameter of the compressible member  650  is greater than a width of the opening  660 . 
         [0035]    Now referring to  FIGS. 5A-5C , different positions of the drive mechanism during riding the pedal scooter  1000  is illustrated. Initially, when the pedal scooter  1000  is not in use (not driven), the compressible member  650 , is in an uncompressed state ‘A’ (See  FIG. 5A ). Now, when the rider applies pressure on a top surface  604  of the inclined pedal  600 , the link  640  moves pivotally downward causing the compressible member  650  to be compressed to state ‘B’ (See  FIG. 5B ). As the first end of the link  640  is connected to the side surface of the front sprocket  610 , the downward movement of the link  640  causes the front sprocket  610  to rotate a first 180 degree in the counter clockwise direction. As the transmission member  630  couples the front sprocket  610  to the. rear sprocket  620 , the 180 degree counter clockwise rotation of the front sprocket  610  causes the rear sprocket  620  to also rotate a first 180 degree in the counter clockwise direction, thereby allowing about half a rotation of the wheels in the counter clockwise direction causing the pedal scooter  1000  to move a certain distance forward. The compressible member  650  is now in a compressed state ‘B’. At this point, when the rider releases the pressure from the top surface  604  of the pedal  600 , the compressible member  650  gradually releases tension by pushing back the pedal  600  to its original position i.e. the uncompressed state ‘A’ of the compressible member  650 . This gradual movement of the compressible member  650 , lifts the pedal  600  pivotally upwards, causing the front sprocket  610  to rotate a second 180 degree in anticlockwise direction, resulting in one complete rotation of front sprocket  610  (See  FIG. 5C ). This movement of the front sprocket  610  causes the rear sprocket  620  to rotate in a second 180 degree in anticlockwise direction, resulting in one complete rotation of rear wheels  210 , thereby allowing the pedal scooter  1000  to move further in the forward direction. Accordingly, by constantly applying and releasing the pressure on the top surface  604  of the pedal  600 , the pedal scooter  1000  may be moved in a forward direction over a desired distance. 
         [0036]    As shown in  FIGS. 6A and 6B , a lever mechanism is configured by detachably engaging an elongated lever  700  to the link  640  through a lever receiving arrangement  710  on the pedal  600 . The lever  700  may be secured within the lever receiving arrangement  710  using securing means such as screws, nut-bolts, threads, and the like. This lever mechanism enables riders to use their hands to drive the pedal scooter  1000  (See  FIG. 7 ). 
         [0037]    The platform  100 , the seating arrangement, the steering arrangement, the braking arrangement, the wheel arrangement and the drive mechanism of the pedal scooter  1000  may be dismantled and packaged using a corrugated cardboard box and additionally, the packaging may include a pamphlet detailing instructions for assembling the pedal scooter. Further, cardboard inserts may be inserted into the package for protecting the dismantled pedal scooter. Additionally, the pedal scooter of the present invention may come in designs featuring different patters and colors that may appeal to all sections of the society.
