Trike {Trik}

The present invention relates to a tricycle, more particularly, to a tricycle, and more particularly, to a tricycle which combines a connecting means with a walking means on which a sub-wheel is mounted and a driving means is mounted on the connecting means to freely move and rotate, The present invention relates to not only being capable of boarding a trike, but also using a connecting means and a propelling means as a walker.

Generally, a trike is a leisure equipment that puts one foot on a footboard with front and rear wheels, rolls the ground and changes direction to the steering wheel, or puts the rear wheel of the three wheels on the left foot and right foot.

It is developed to complement the monotony and the danger of the conventional two-wheeled kickboard. It has two decks that can ride the front wheel and the hair. It is connected with the link frame. The front wheel is equipped with the handle member, The deck has one or more wheels mounted thereon and a brake is provided on the handle of the handle member to brake the wheels mounted on the deck as the brake is operated. This is a trikke or tri- And is sold with a new name.

And patent registration No. 13014 Tri-Circle Kickboard, Utility Model Registration No. 405734 'Tricycle Kickboard' and 2008 Patent Application No. 84236 'Tricycle Kickboard' are known and already commercialized.

The driving of the trike is such that the occupant moves his / her body weight to the front, back, right and left at appropriate time in accordance with the body-centered rhythm, and performs the act of opening and closing the legs and at the same time, will be.

In particular, it is possible to achieve a higher speed in the process of pushing the outer foot (deck) outward while moving the weight to the left and right decks.

However, in the conventional triacic kickboard or trike, the turning radius of the deck is limited, and since the turning point is one, there is a problem that the driving force is limited because the angle at which the deck is pushed is limited.

In addition, the application No. 10-2012-0111036 filed by the present applicant discloses a drawback that the slide roller located at the center is shifted into the slider-eyed hole of the link frame when the footrest is rotated to the left and right, thereby causing frequent friction between the link frame and the slide roller There is a problem that abrasion easily occurs.

In addition, when the weight is placed on the heel unintentionally because it is one rear wheel, there is a drawback that the center is disturbed and the brake is frequently operated, and the fixed cover coupled with one fixing bolt due to frequent vertical and horizontal rotation, There was a problem.

Thus, the tri-circle kickboard of the registered patent No. 10-1374020 registered by the present applicant can alternatively be advanced to the skate-riding form along the slide ball while stepping on the footboard having the stable center of gravity to improve the driving force of the rear wheel It is not possible to rotate the handle freely, and it is also inconvenient to remove the S type frame and the link frame and to use it as a walker.

In other words, while you can not take artistic actions with your knob while driving a kickboard, if you run on uneven roads, you will get heavy weight at the center connection of the S-shaped frame and link frame, It was not possible to remove some of them and use them as a walker.
