Description

Separable roller skid accelerated by foot step and transported by hand and foot step}

The present invention relates to a detachable roller sled, and more particularly, a set that can be freely ride by centering on a flat land or asphalt road, not on snow or ice, as well as stretchable according to the size and length of a foot. It is about a separate roller sled that enters and moves with hands and feet that can be used by all family members.

In general, a sled is a device that drags or slips a person or an object on a snow or ice sheet, and is also called as a falcon, a falcon, a falcon. As you can see from the Chinese characters '雪 馬' and '雪 鷹', it means running fast like a horse or hawk. Some people think that the origin of the sled is `` snow horse '' in Chinese characters, but it is common to think that `` snow horse '' is only written in Chinese characters.

Sleds include sleds that carry loads, sleds on foot, and sleds for children to play with.

The sleds that carry the goods are bent to round the floor and the front and rear ends are bent upwards to make it easier to slide. There are thick boards on the left and right, with two boards between the left and right, and connect them to six or seven horizontal lines. Tie a string to the front rung to hold it.

This sled was widely used in the construction of Joseon Dynasty. In the contents of Ui-Geum, which recorded the reconstruction of Changgyeonggung Palace and Changdeokgung Palace in the 17th century, sleds must be used as tools for carrying goods, and 9 sleds were used for the construction of Suwon Castle at the end of the 16th century.

The sled on your feet is not constant in size. Generally around 100cm is used, but some children are about 50cm. It is about 12cm wide and 5cm thick. The front of the sled is bent to lift upwards like the beak of a ski. In the middle of the four holes are to be drilled and strapped to tighten the feet. Use your spear as a stick for skiing. The feet are fixed only on the sides and the heel is free to move. Use this heel when turning left and right or braking. If you wear this, it is easy to move even in woods, which is convenient when hunting.

Sledding is a game that children play on sleds on snow or ice. There are many different shapes of this sled, but the most common one is a piece of wood of the right height placed side by side on the bottom of the board where the child can sit, and a bamboo or iron filed under it to slide well on snow or ice. When riding, hold a long awl in both hands, use it to dip the floor and go forward, change direction or stop.

However, these sleds have a problem that there are place restrictions that can be used only in slippery places such as on snow or ice.

The present invention is to solve the conventional problems as described above, as well as to ride freely while holding the center of the hand on a flat land or asphalt road, not on snow or ice, and stretchable according to the size and length of the foot Its purpose is to provide a detachable roller sled that can be moved and moved into the hands and feet that all family members can use with the set alone.
