Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a support structure for a running surface block in a water chute.

(Prior Art) A water chute is a type of slide that uses water as a lubricant. In other words, the water chute is by flowing water onto a gutter-like sliding surface.

It reduces the frictional resistance between the sliding surface and the body of the person sliding on it, and also cools and removes the frictional heat.The frictional resistance is extremely small, and there are almost no problems such as wear of clothing due to friction. For this reason, runways are long, tens of meters or more. To construct a water chute, pillars are established at regular intervals at the installation location, and the runway is made by splicing factory-produced gutter-like runway blocks several meters long to the desired length. The joint part is fixed to a support, so that it is supported by the support in a state of being suspended from the support.

(Problems to be Solved by the Invention) By the way, when a person slides down a runway, the weight and centrifugal force of the person sliding down the runway are applied to the runway. Of course, this force is not constant with respect to the runway, but moves downward from the top at a considerable speed, so for example, at the fixed part between the runway block and the support, there is a strong impact every time a person slides down the runway. force will come into play.

The sliding surface blocks are made of FRP, such as glass fiber reinforced polyester resin, and are relatively weak against repeated impacts.Therefore, with conventional water chutes, the parts that are fixed to the pillars may break during use. As mentioned in Section 2, the sliding surface block is made of FRP, so when you slide down on it, the sliding surface block will bend slightly due to your weight, etc. Since the fixed portion, that is, the seamed portion at both the upper and lower ends of the sliding surface block, does not flex, the skier will experience an unpleasant shock feeling every time he passes through this portion.
Therefore, the parts fixed to the pillars have traditionally been difficult to damage.
Furthermore, there was a desire to develop a water chute that would not cause discomfort during use.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned points, and includes an elastic material interposed between the sliding surface block and the strut, so that this portion of the sliding surface block is not affected by external force. By moving up and down, it absorbs the impact force between the sliding surface block and the supports, reducing the possibility of damage to this part and eliminating discomfort when passing through this part.

Hereinafter, the present invention will be specifically explained based on illustrated embodiments.

In the figure, numeral 1 is a sliding surface block, and 2 is a support. The sliding surface block 1 has a substantially cylindrical shape with a cutout at the top,
Flanges 3 are formed on both end edges for connecting with other runway blocks of the same shape, and by connecting a large number of runway blocks, a runway of a desired length can be constructed. . To explain the sliding surface block 1 in more detail, it consists of a bottom member 4 and a side member 5, each having a substantially semicircular cross-sectional shape, and fins 6 project outward from both edges of the bottom member 4. At the same time, fins 7 corresponding to the fins 6 are formed on the lower edge of the side member 5, and the bottom member 4 and the side member 5 are joined by bolting or other means. It was integrally connected.

Incidentally, the sliding surface block 1 is formed using robust FRP such as glass fiber reinforced polyester resin. The support column 2 supports the connecting portion of the sliding surface block 1, and has a υ-shaped support arm 8 attached to its upper part.

This supports the fins on both sides of the joined collar 3 of the sliding surface block 1. In addition, in the figure, the left and right pillars 2 are integrally formed, and this and the support arm 8
An example is shown in which the columns 2 are connected via bolts 9 to make the column 2 expandable and retractable. By integrating the left and right struts 2, the spacing between both struts is kept constant, making the construction of the struts simple and reliable. For example, in a curved part of the runway, the struts 2 on the outside of the curve are It is designed to be slightly longer to cope with the centrifugal force acting on the runway. The support arm 8 and the fin 6 are designed to prevent direct contact and provide cushioning between them, and between the support plate 10 formed at the upper end of the support arm 8 and the fin 6. Synthetic rubber 11 having appropriate elasticity is interposed between the fins 7 and synthetic rubber 12 having appropriate elasticity is placed on the fins 7, and bolts 9 are loosely fitted onto these.

(Function) When a person skis down this water chute, when the person passes through the connection part of the sliding surface block 1, that part tends to descend due to the person's weight, etc. Then, that tendency is transmitted to the fin 6, and this and the sliding surface block 1
trying to descend as one. The force is then transmitted to the synthetic rubber 11 and absorbed by its elasticity. Furthermore, after the person passing through this area, the fin 6 is immediately pushed up by the elasticity of the synthetic rubber 11, but at this time, the synthetic rubber 12 is interposed between the fin 7 and the bolt head 13. Therefore, the fin 7 does not collide with the bolt head 13.

(Effects of the Invention) As described in detail above, the present invention forms a runway block constituting the runway of a water chute by a bottom member and a side member, has fins protruding from both sides thereof, and supports the fins by supports. A sliding surface block is attached to a column by supporting it, and in particular, the column has an upper end shaped like a square, and a synthetic rubber having appropriate elasticity is interposed between the receiving plate and the fin. As a result, the FRP fins do not come into direct contact with the receiving plate, and the external force applied to the fins is absorbed by the synthetic rubber, preventing the fins from colliding with each other. is significantly reduced. In addition, the elasticity of the synthetic rubber gives the runway elasticity to the connecting parts of the runway blocks, which eliminates the unpleasant feeling of impact when sliding down this part, allowing you to enjoy a comfortable play. be.
