Description

Fish board {fish board}

The present invention relates to a fish board, the handle is attached to the front of the three-wheel frame made of a swivel caster, the rear of the frame is attached to the footboard attached to the rear wheel so as to rotate left and right to rotate the handle to the left or right By returning the movement, the fish can move forward and steer as if moving the water by moving the head and body, allowing children and others to play and play safely and fun indoors and outdoors.

Recently, kickboards and esboards have been developed as a vehicle that can be easily enjoyed by children and young people in vacant lands and parks.

Kickboard is composed of a handle and a connecting shaft and a board is provided with a steering device, the bottom of the board is composed of wheels combined one by one back and forth.

The kickboard of such a configuration is a driving force generated in the process of pushing the ground with one foot on the board while the user holds the handle with both hands, and the handle is provided so that the steering is not difficult, but the board is moved back and forth. As it is supported by two wheels, not only is it difficult to center, but also the user has to push the ground continuously with one foot in order to keep propulsion, and the user soon feels tired, and in addition, the user has to look ahead and ground alternately. In the car in front of the car does not recognize the obstacle there is a problem such as a safety accident occurs.

On the other hand, unlike the kickboards, a pair of scaffolds with inclined casters at the bottom are arranged back and forth, and the S-boards are connected to each other by a connecting shaft that can be rigid and torsional. When ankle motion of both feet is applied to each board, the firmness and torsional motion are applied to the inclined caster installed on the lower side of the footboard, and the horizontal component causes the esboard to move forward.

Like the kickboard, the S-board of this structure is difficult to grasp because the board is supported by the front and rear two wheels, it is difficult to learn how to ride as a person with a weak athletic nerve, and the user gains momentum by the user's ankle movement. Tiredness or continuous ankle movements can cause stress on the ankles. Also, the propulsion force is not enough to enjoy the speed. In addition, there is no handle to adjust the direction. However, the direction that is difficult to adjust because the direction to go ahead has a problem that it is not easy for beginners or children to use.

The present invention has been made to solve the above problems, the object of the present invention is easier to learn than the esboard, by turning the handle to the left and right or by turning the waist to the left or right, or by mixing these operations Effective propulsion is not difficult or tiring compared to conventional kickboards, and it provides a new way of riding that allows children and beginners to exercise safely while using it.

In order to achieve the above object, the present invention comprises a frame in which one front wheel and two rear wheels each made of a swivel caster are arranged in a triangular shape; A handle detachably attached to the front upper portion of the frame; A footrest rotatably attached to an intermediate point between the left and right rear wheels of the frame and having a rear wheel attached to a rear lower portion thereof; It provides a fish board comprising a.

In the present invention, the front and rear wheels and the rear wheels are attached to the frame and the footrest so as to have a caster angle, respectively, so that the direction of the wheel can be smoothly switched from side to side while following the left and right rotational motion of the frame and the footrest.

The name of the present invention is called a fish board (fish board) is attached to the handle in front of the three-wheel frame made of a swivel caster, the rear of the frame is attached to the footboard with the wheel attached to the left and right to rotate the handle This is because the principle of driving forward and steering from the ground is possible by moving the left and right or the back and the left and right to move the water by moving the head and body from side to side. The movement principle is different from the existing kickboard or esboard, and it is not hard to turn the handle to the left or right by using the arm or to turn the waist to the left or right. Even if the movement is not done, children can easily learn the driving feeling indoors and outdoors without effort You can play.

In the fish board of the present invention, the footrest is further provided with a pedal-type brake that rubs against the ground so that it can be stopped when necessary.

In the fish board of the present invention, a support bearing for supporting the left and right pivoting of the scaffold is provided between the frame and the bottom of the scaffold to distribute the load applied to the scaffold and to smoothly rotate the scaffold. A stopper in contact with the support bearing is provided on the bottom of the scaffold so that the rotation angle can be limited to within 45 degrees of the left and right.

The present invention attaches the handle to the front of the three-wheel frame made of a swivel caster, the rear of the frame is attached to the footboard attached to the rear wheel so as to rotate left and right to rotate the handle to the left or right to rotate the waist to the left and right As a fish moves head and body from side to side and moves in the water, it is possible to move forward and steer on the ground so that children can easily move indoors and out without effort even if they do not have a special sense of motion or skill. It has a useful effect to safely learn the driving senses and ride.

It is.

Hereinafter, various methods of riding the fish board of the present invention will be described.

1) Driving using the steering wheel

This method is the simplest, safest and rudimentary way of driving, with the two feet (not shown) raised on the footrest 30 as shown in FIG. If you hold the handle 20 with both hands and push the handle 20 to the left and right side while pushing both feet on the footrest 30 while pushing, the frame 10 integrally connected to the handle 20 also has the left and right directions. While rotating, the fish board gains propulsion by the horizontal force in the left and right rotational directions of the frame 10. When the steering wheel is slowed down, it moves slowly and the faster the steering wheel rotates. Travel speed will increase.

At this time, the change of direction can be made by turning the handle more toward the direction to be advanced or can be freely adjusted by biasing the direction of the direction of the weight of the weight placed on the scaffold.

2) Turn around your waist

This method is also a simple and safe novice driving method, but it requires some tips and exercises to give propulsion to the fish board by moving the torso (back) on the fish board. After pushing the fish board forward slightly while raising both feet on the footrest 30, the handle is handled as described in 1) when the occupant turns the waist to the left and right as shown in FIG. In contrast to the operation of turning 20) from side to side, the frame 10 and the footrest 30 rotate left and right about the mutual rotation axis 33 by the reaction of rotating the footrest 30, as if the fish body and tail portion. By moving the left and right in the water by moving the fish board is a forward run is made, the waist turning motion to increase or speed up Lock the running speed is increased.

In this method, the change of direction can be easily adjusted by turning the steering wheel in the desired direction.

3) Using handle and footboard at the same time

This method is to use the method of 1) and 2) at the same time, in this case, the operation of turning the handle 20 to the left and right and the waist to the left and right with both hands while riding on the footrest 30 In the case of the opposite direction, the speed of the fish board can be made faster, and the direction change can be used by selecting an appropriate one from the tips described in 1) and 2) above.

In this method, since the arm movement and the waist and leg movements are simultaneously performed in combination, it is possible to stimulate the growth plate and to have sufficient exercise effects in the growing children.

4) Grab the handle and ride like a skateboard

The method is more difficult than the operations of 1), 2) and 3) described above, and there is some risk, so it is preferable to attempt this method after mastering the operations of 1), 2) and 3). Similar to riding an esboard, as shown in FIG. 6, the occupant stands laterally with respect to the front and rear direction of the fish board, and grabs the middle part of the handle 20 with one hand, and one foot is the footrest 30. In the middle of the foot and the other foot is placed on the back (tail) of the footrest (30) in the state of moving the rear foot left and right, the footrest 30 and the rear wheel 31 rotates from side to side, the driving force is generated, At this time, by turning the handle to the left or right by using the hand holding the handle 20, driving in the desired direction is possible.

5. Remove the handle Like an esboard ride

This method is similar to the method of 4) above, but removes the handle attached to the frame and rides in the same way as riding an S-board (or skateboard). When the rear foot is raised on the back of the footrest and the front foot and the rear foot are rolled to the opposite side to each other, the front and rear wheels and the rear wheel attached to the frame and the footrest swing in opposite directions, respectively, so that the driving force is generated. At this time, the change of direction is made by changing the direction of the direction to advance the weight center of weight.

In addition, the fish board of the present invention may acquire a propulsion by converting various body movements into rotational motions of the frame and the footboard by acquiring a riding method after the above method is mastered in addition to the above-described method.
