The present invention is to configure the wheel on the sled to enjoy the sled on the road regardless of the season, in particular, the sled is elastically supported by the elastic bar (Elastic bar) formed with the rear wheel to avoid the shock generated when driving on the bumpy road surface By fully buffering, the user can enjoy the sled comfortably, and when it is desired to change the running direction of the sled, the user is directed to the roller sled using the elastic bar which naturally changes the running direction of the sled when the user moves in the direction to rotate the center of the body.

In general, sleds are used as a tool for transporting people or objects while driving on snow or ice, and in the modern age, they have been spotlighted as leisure sports, but sleds can be enjoyed only in winter with snow or ice.

Applicant has applied for a "roller jumping sled" (patent application No. 2005-12248) that can enjoy the sled on a general road regardless of the season by configuring the wheel on the sled to solve the above problems, but the above "Roller jumping sled" is because the elastic bending portion and the backing plate is integrally configured to cushion the elastic bending portion is easily broken, it is very inconvenient to maintain and repair, and had a disadvantage in that it takes a lot of money in maintenance and repair.

In order to solve the problems described above, the present invention has two elastic bars configured with rear wheels in the lower part of the sled, so that even if it is used for a long time, the damage is less, and the maintenance and repair are simple, and the driving direction can be changed. It is an object of the present invention to provide a simple sled.

In order to achieve the above object, the present invention provides two steering wheels (3) rotatable on the front lower portion of the footrest (2), and a fastener (5) on which the rear wheels (6) are inserted and fixed ( 4) is bolted to the lower portion of the footrest (2) at a predetermined interval from each other, two elastic bars (4) elastically support the user's load on the footrest (2) is configured to run the sled (1) do.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of the present invention, Figure 2 is a side view of the present invention, Figure 3 is an exploded perspective view of the present invention.

In the sled according to the present invention, as shown in FIGS. 1 to 3, a steering wheel 3 that is rotatable is formed at the front lower portion of the footrest 2, and a pair of elastic bars are provided on both lower sides of the footrest 2. (4) is bolted to the scaffold (2) at a predetermined interval from each other.

One side of the elastic bar (4) is bolted to the fastener (5) formed with the rear wheel (6), the cylindrical stick fixture (9) formed with the stick groove (8) is inserted into the fixing hole (10) of the footrest (2) Fixed

In the present invention configured as described above, when the user climbs on the footrest 2 and tires the ground with the stick 11, the steering wheel 3 and the rear wheel 6 of the sled 1 roll the ground as shown in FIG. (1) will run.

At this time, the pair of elastic bars (4) formed on the bottom of the sled (1) is a pair of elastic bars (4) buffers this even if you run on a bumpy road surface by supporting the load of the user who climbed on the sled (1) The user can ride comfortably.

The sled 1 according to the present invention not only cushions the shock transmitted to the user when driving on a bumpy road surface, but also quickly and easily changes the driving direction when an obstacle appears suddenly in front, thereby preventing a safety accident. .

5 is a state diagram of the sled 1 in a straight running state, FIG. 6 is a state diagram of the sled 1 in a left turn state, and FIG. 7 is a state diagram of the sled 1 in a right turn state.

As shown in FIG. 5, when the user moves the center of the body to the left while driving straight on the sleigh (1), the user of the pair of elastic bars (4) configured under the footrest (2) as shown in FIG. The elastic bar 4 on the left side that has moved to the center is further stretched under the load, and the elastic bar 4 on the right side is inclined to the left while the load decreases.

At this time, the steering wheel 3 is rotated to the left while the footrest 2 is inclined to the left, and the running direction of the sled 1 naturally changes to the left.

In addition, when the user moves the center of the body to the right in the state running straight on the sleigh (1) as shown in Figure 5 of the pair of elastic bars (4) configured under the footrest (2) as shown in FIG. The elastic bar 4 on the right side, which moves the center of the user, is further spread under the load, and the elastic bar 4 on the left side is inclined to reduce the load and the footrest 2 is inclined to the right side.

At this time, the steering wheel 3 is rotated to the right while the footrest 2 is inclined to the right, and the running direction of the sled 1 naturally changes to the right.

As described above, when the user suddenly sees an obstacle while driving in the sled 1 and moves the center of the body in the direction in which the user wants to rotate, the running direction of the sled 1 rotates in the direction of the center movement of the user, You can easily change the driving direction.

In the present invention, the sled 1 and the stick 11 are always stored and carried together since the sled 1 travels while the ground is tired with the stick 11 as shown in FIG. 4.

As illustrated in FIG. 8, the stick 11 may be inserted into and stored in the cylindrical stick fixture 9 formed on the footrest 2 to prevent the loss of the stick 11.

In addition, in order to ride the sled (1) by holding the handle (7) formed on the footrest (2) of the sled (1) can be carried with the sled (1) and the stick (11), as shown in Figure 8 Stick 11 into the stick groove (8) of the), the stick 11 can be moved to the play place simply by pushing the sled (1) as a handle.

That is, the technical core of the present invention is configured to a pair of elastic bars (4) having a rear wheel (6) formed on one side in the lower part of the footrest (2) of the sleigh (1) to cushion the shock generated when driving on a bumpy road surface So that users can enjoy sledding comfortably,

In order to change the running direction of the sled (1), when the user moves the center of the body in the direction to rotate the elastic bar (4) in the direction the body is moved as the sled (1) is inclined Naturally, the driving direction of the sled 1 is changed so that it is simply configured to change the running direction of the sled 1 is the technical core of the present invention.

As described above, the present invention configures a wheel on the sled 1 so that the sled 1 can be enjoyed on a general road regardless of the season, and in particular, the rear wheel 6 of the sled 1 is provided on the elastic bar 4. It is elastically supported so that the user can enjoy the sleigh (1) comfortably by buffering the shock generated when driving on a bumpy road surface, and the user wants to rotate the center of the body to change the running direction of the sleigh (1). When moving in a direction to naturally change the running direction of the sled (1) is a very useful invention that can be changed at high speed and free running direction.

Claims (1)

A steering wheel 3 capable of rotating is formed at the front lower portion of the footrest 2, The user's load on the footrest (2) is bolted to the lower part of the footrest (2) at predetermined intervals by the two elastic bars (4) into which the fastener (5) having the rear wheels (6) is inserted and fixed. Two elastic bars (4) to support the elasticity and roller sled using the elastic bar, characterized in that configured to run the sled (1).
