Description

Two feet pedaling folding type scooter

The present invention relates to a two-pedal scooter, in more detail, unlike a conventional kickboard-type scooter that moves forward with a propulsive force to spur the ground with the other foot while holding a handle and placing one foot on the footrest. It is mounted on the bottom of the footboard by stepping alternately with both feet using the symmetrically formed pedals of the up and down reciprocating drive type, which are located on both left and right sides and rotate up and down in a closed angle without rotation. The rear wheel that rotates in conjunction with the power transmission unit is optimized for the forward and backward reciprocating drive gears and driven gears and the short reciprocating process of the up and down pedals. The rear wheel has a plurality of driven gears in short circuit by lever It is a scooter that can freely change direction or reverse when rolling a scooter without laying by installing a device. As a braking device, it is equipped with front and rear brakes for good safety and coil springs are installed on both sides of the front wheel hawk and the rear wheel. The cushioning effect is relieved of impact, so the riding comfort is excellent, and it is folded and minimized by simple operation, so it is convenient to store or carry.

As described above, the conventional kickboard-type scooter is a sports equipment that can be repositioned using a vertical handle formed by placing a foot on a footboard with two rear wheels, rolling the ground, and a vertical handle. It is a non-motorized moving device that has been popularly popular in Korea as a short-range vehicle or a children's exercise device.It is light and foldable, it is easy to carry, and it is designed to suit the taste of young urban people. Not only running, but also a little speed can be used to jump stunts, you can taste the two effects of fun and exercise, but because it kicks the ground with one foot, it is uncomfortable to use for beginners, uncomfortable use, and kicking the ground intermittently to drive Structure and operation winry to get Since it is impossible to continuously drive, and the brake device is equipped with a short braking distance on the rear wheel only, water is stuck on the road, or the brakes are less likely to be caught compared to the driving speed in case of steep slope or high speed. In addition to the ankle, it is difficult to achieve high speeds on flat lands, and it is impossible to drive uphill. Excessive force is applied to only one foot. Since the amount of exercise is insufficient, there is a problem that the utilization of the adult who prefers a calorie-consuming exercise device to play only a role as a play equipment rather than an exercise device.

As a related art related to a scooter (kickboard) that is powered by a pedal, Utility Model Registration No. 222180 shown in FIG. 6 "Pedalable kickboard" (application date: 2000.10.18), generates power and transmits power like a bicycle. As a means of driving by driving the rear wheel using a pedal and a chain, it is possible to drive high speed by using a structure that generates power by rotating a common asymmetric bicycle pedal that is staggered from side to side. There is a problem in that the pedal device is located at the rear of the footrest as a combined structure for rotating the pedal, and the utility model registration No. 222777, "Kickboard capable of power transmission" (application date: November 17, 2000) of FIG. In addition to the general shape of the kickboard structure, a single pedal is attached to the rear end of the rear wheel to maintain driving continuity. This eliminates the intermittent driving, which is a disadvantage of the kickboard, but has a problem in that the pedal is located at the rear end of the steering wheel on a elongated footboard at a rear end of a certain distance on the elongated footboard, which is inconvenient to use, inferior in stability, and lack of exercise. .

In addition, Korean Patent Application Publication No. 2003-0015465 No. 2003-0015465 of the "kickboard equipped with a pedal device" (published date: 2003.2.25) is also a foot that does not press the pedal on the frame equipped with a general kickboard-shaped handle It is attached to the footrest to support the structure and the driving wheel by connecting one pedal to the rear wheel of larger diameter than the front wheel, which also increases the safety compared to the above-described conventional technology, but the pedal is located at the rear, which is inconvenient to use There is a problem that can not run fast and lack of exercise.

The present invention has been made in order to solve the above problems, unlike a kickboard-type scooter that moves forward with a driving force that spurs the ground with a foot, a stepping-type power generator that steps on the foot, and reciprocally formed up and down symmetrically toward the front of the footboard. Drive-type pedals are mounted on the bottom of the pedal board, which converts the up and down reciprocation of the pedals into rotational movements to transmit power, and the rear wheels are driven continuously by a power transmission device of chain gears of different diameters to drive forward continuously. An idling device that pushes and rotates the driven gear, which is engaged with the gear and chain by the spring's elastic action on the rear wheel shaft, is installed to short-circuit by installing an idling device to shorten direction. Front and rear brakes and cushioning It is an object of the present invention to provide a two-wheeled pedal-drive scooter with a structure that improves the driving, riding comfort, safety, convenience, and movement effect by being folded.
