Description

  The present invention relates to a skateboard, and more particularly to a skateboard having a support structure that can accommodate a hard, soft, or mixed type ground and that can adjust an area for supporting a deck.

  There are many types of skateboards or exercise equipment similar to skateboards. The structure of a general skateboard is a four-wheel structure having four rollers. In addition, a kickboard having a similar structure is provided with a turning means at the front end and a braking means at the rear end. It is. These are all provided with rolling elements such as rollers and run while rotating the rolling elements, but cannot be applied to soft ground. In the case of a soft ground, for example, a snowboard or a part that directly contacts the ground is formed in a plate shape and slides.

  Taiwan Utility Model Application No. 90217272 provides a board structure for both snow and ice. Taiwan Patent Application No. 89107132 provides a snow slide, and Taiwan Utility Model Application No. 84207845 provides an improved structure for a snowboard. All of these conventional techniques are configured as snowboards, and cannot be applied to other ground than on snow. In addition, Taiwan Utility Model Application No. 89219751 provides a sliding board that has an additional structure and can be applied to any ground. However, when the sliding board according to the invention is used on snow, the rolling element easily fits in the snow. It will hinder the gliding.

  U.S. Pat. No. 4,165,091 discloses a plate-like sliding structure provided separately on the bottom surface of the sliding board. However, since the plate-like sliding structure has a small area, if it is used on snow, it cannot easily slide into the snow. Therefore, the sliding board provided by the patent can only be used on hard ice.

  Also, a structure with a caterpillar has been announced. Taiwan Utility Model Application No. 84216969 provides an electric shoe with a caterpillar. Taiwan Utility Model Application No. 82210566 provides a skate with a multi-purpose caterpillar. However, the structure of the caterpillar is complicated, heavy and inconvenient to use, and expensive to maintain.

In addition, current skateboards have a fixed distance between their roller supports, and the same area that supports the deck of each roller support, so their stability and agility are also fixed. It is a typical one. Therefore, for example, it is impossible to respond to various needs related to speed when sliding on a straight line, or agility when changing direction. And it cannot adjust efficiently according to this need, or cannot replace a roller support part.

The adjustment seat 50 and the mounting seat 40 are connected together.

  The adjusting means A provided at both edge portions of the bottom surface of the deck of the skateboard 10 can change the distance between the adjusting means A by adjusting the position of the adjusting seat 50 as disclosed in FIG. By such adjustment, the area in which the support device 30 supports the deck can be adjusted as necessary when the skateboard 10 is actually used. In the state disclosed in FIG. 3, the distance between the adjusting means A is the shortest, and the distance between the direction changing devices 20 connected to the respective adjusting seats 50 is also the shortest. Accordingly, the area supported by both support devices 30 is minimized. In such a state, the agility of the skateboard is increased, which is convenient for the operation of changing the direction. Further, when the adjustment seat 50 is adjusted to the position closest to the outer side of the front and rear mounting seats 40, the distance between the support devices 30 becomes longer and the area to be supported increases. Therefore, the radius of the curve drawn when the direction is changed becomes large, and this is applied when the vehicle runs on a straight line or changes the direction by drawing a large curve. In this way, the user can adjust for different needs in actual use.

  The skateboard according to the present invention has the above-described structure, and can achieve the following effects. That is, it is possible to deal with the ground in different states. As shown in FIG. 3, when the skateboard according to the present invention is used on a hard ground, each guide roller 33 and the two support rollers are exposed from the main body 31 of the support device 30 so that the outer peripheral surface of the rollers is Touch the ground. Further, when used on a soft ground such as sand or snow, if the guide roller 33 first guides the main body 31 and crosses the convex portion of the ground as disclosed in FIG. An efficient support action occurs in the support section 310, and the support and rolling actions also occur in the two support rollers 33A on the support section 310. Therefore, the skateboard 10 can smoothly slide on the soft ground. In the case of a mixed type ground, the above functions are used together.

  Further, the skateboard according to the present invention has a preferable buffering action due to elasticity. That is, the main body 31 is formed by bending a plate having elasticity, or formed in an arch shape by integral molding. For this reason, it has favorable elasticity, and when it receives an impact when the ground condition changes or when different operations are performed, the body 31 changes its shape as disclosed in FIG. The impact force transmitted to the can be minimized. Moreover, since the joints between the guide roller 33, the support roller 33A, the direction changing device 20, and the main body 31 all have an elastic buffering action, the impact force can be minimized. Therefore, the skateboard according to the present invention has high safety and practicality.

  Moreover, the skateboard according to the present invention can automatically adjust the overall structure. In other words, the support portion 310 of the main body 31, the guide roller 33, and the support roller 33 </ b> A are integrally connected and interact with each other. In other words, when one performs an operation, the other performs an operation that elastically deforms or recovers in accordance with the operation, and automatically adjusts to provide a structure that interacts with each other.

  Further, the skateboard according to the present invention can greatly increase the agility. That is, the user can change the position of the support device 30 of the adjustment device A according to different needs. Therefore, different characteristics can be imparted to the skateboard, and different needs of the user can be met.

  The foregoing has been a description of the preferred embodiment of the present invention and is not intended to limit the present invention thereby. Therefore, any modification or change that can be made by those skilled in the art falls within the scope of the present invention.
