Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an improvement of the support structure of the runway body in a large slider installed in an amusement park, a leisure land, a sports land, etc.

(Problems to be solved by conventional technology and ideas) Large slides with a runway body arranged in a continuous meandering or spiral manner from an observation deck set at a high place to the ground are being constructed in a wide range of places. .

Conventionally, the runway body 14 having this continuous rigidity
As a support structure, it may be directly supported by a support frame at a predetermined position, or it may be slidably supported on the upper surface of the tip of the horizontal beam 12 extending from the side surface of the base column 11 as shown in FIG. A structure is adopted in which the seat is supported via an assembled saddle 13. The runway body 1 also has continuous rigidity.
4. Displacement due to expansion, expansion and contraction due to changes in outside temperature, and dimensional errors during assembly are due to saddle 1.
3 was absorbed by the sliding portion 15 on the lower surface.

That is, in this conventional support structure, the horizontal beam 12 itself does not expand and contract, but the horizontal beam 1
2 is formed of a single rigid body, and the displacement of the runway body 14 is absorbed by the saddle 13 that slides on its tip. Therefore, the sliding part 1 of the saddle 13
5 has a disadvantage that the structure becomes complicated and the number of man-hours for processing and manufacturing and on-site assembly increases.

That is, the sliding portion had to be finished smoothly, and it was also necessary to provide a stopper 16 to limit the sliding limit of the saddle 13.

Furthermore, in order to ensure the function of absorbing displacement, the saddle 13 and the horizontal beam 12 are joined in a loosely fitted state. Therefore, the runway body 14 is
The disadvantage is that the support is unstable because it is not firmly fixed to the base.

In this way, there is a need to loosely fit the saddle 13 and the horizontal beam 12, and at the same time there is a need to firmly fix the continuous runway body 14, and in order to satisfy these conflicting conditions, teeth,
The sliding range of the saddle 13 is naturally limited.

Therefore, if a large manufacturing error occurs when molding the runway body 14, or if a large error occurs in the installation dimensions during on-site assembly,
Since these errors could not be absorbed, there was also a construction problem in that the installation work during on-site assembly was extremely difficult.

In addition, in order to facilitate the installation work during this on-site assembly, a chute (runway body) constructed by attaching a flexible web to a stirrup-like holder is attached to the tubular arm portion into which the second arm portion is inserted. Accordingly, an invention that is adjustable and fixed to a support post is disclosed in Japanese Patent Application Laid-Open No. 59-135084. However, the support structure according to the present invention has a so-called non-extensible structure in which the tubular arm portion into which the second arm portion is inserted is locked by a stop screw, so when it is attached to a continuous runway body that has rigidity, the outside temperature There was a problem in that it was not possible to absorb the expansion, extension, and contraction of the runway body caused by changes in load due to the presence or absence of people sliding down the slope.

Furthermore, since this equipment is often constructed outdoors, it also has the drawback of being weak in terms of weather resistance and corrosion resistance. That is, the sliding portion 15 of the saddle 13 is always exposed to the outside air, and dust may accumulate there.
There is a drawback that rust occurs and the sliding function is inhibited.

This invention was devised to solve the above-mentioned problems, and it is a horizontal beam that firmly supports and fixes a continuous runway body with rigidity, and has the ability to expand and contract to compensate for displacement and assembly errors of the runway body. It has a support structure that can absorb water, and has a very simple structure and is weather resistant.
The purpose is to provide a support structure for a runway body that also has excellent corrosion resistance.

(Means for Solving the Problem) In order to achieve the above object, the support structure according to this invention is configured as follows.

In other words, a horizontal beam extending horizontally from the side of a base column erected on a foundation is fixed at one end horizontally at each of the upper and lower positions in alternately opposite directions on the side of the base column, and the base beam It consists of an arm that expands and contracts into the hole at the other end of the end beam, and a saddle is fixed to the upper surface of the tip of the arm, and the rigidity of the saddle is arranged spirally around the base column on this saddle. This is a structure that supports a continuous runway body.

(Example) Next, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a half-sectional view of the entire large slider to which the support structure of the present invention is applied, and FIG. 2 is a partial sectional view showing an enlarged portion of the horizontal beam 2 with a portion removed.

In the overall view shown in FIG. 1, an example is shown in which a continuous runway body 3 having the same cylindrical rigidity is arranged spirally from a starting point 8 of an observation deck 7 set at a high place to an ending point 10 near the ground 9. It shows. The runway body 3, which is molded from a resin material such as fiber-reinforced plastic (FRP), polycarbonate, or acrylic, is constructed of horizontal beams 2 that protrude from the upper and lower positions of the outer surface of the base pillar 1 in alternately opposite directions at appropriate locations. It is supported on top via a saddle 6.

This horizontal beam 2, as shown enlarged in Fig. 2,
a base beam 4 having one end fixed horizontally to the side surface of the base column 1;
A saddle 6 is fixed to the upper surface of the tip of the arm 5, and a continuous runway body 3 having rigidity is supported on the saddle 6.

The specific structure of the horizontal beam 2 is to prepare two tubes with polygonal cross sections such as cylindrical or square, insert the other tube that will become the arm 5 into the tube that will become the proximal end beam 4, and then It is constructed by assembling pipes that can be slid horizontally.

In any case, any structure may be used as long as the arm 5 is telescopically fitted into the hole at the other end of the base beam 4.

In order to improve sliding properties, a lubricant and rust preventive agent such as grease is applied to the sliding parts.

Further, in this embodiment, the runway body 3 has a duct structure with a circular cross section, but it goes without saying that the shape can be arbitrarily selected as long as it is a continuous rigid body that does not change shape even when a person slides down the runway. That is,
It may also be an open type with a continuous rigid body having a U-shaped cross section.

(Function and Effect) Expansion, expansion, and contraction due to temperature changes of the continuous runway body with rigidity, manufacturing errors and misalignment of the installation position of the runway body during on-site assembly can be prevented by the sliding part of the horizontal beam with the above configuration. It is easily absorbed in the.

Therefore, the expansion, extension, and contraction of the runway body due to temperature changes during operation is absorbed, so no undue stress is applied to the runway body or other structural members, extending the life of the slider. can.

Furthermore, in the horizontal beam structure of the present invention, since the saddle 6 and the armrest 5 are integrally connected, it is possible to stably and firmly support the runway body.

In other words, the conventional saddle 13 and horizontal beam 12
This eliminates the instability of support that would occur when the horizontal beams are loosely connected, and the sliding part is simplified, so the manufacturing cost of the horizontal beam can be reduced.

Furthermore, since the range of extension and contraction of the arms of the present invention is much larger than the sliding range of conventional saddles, the ability to absorb the displacement of the runway body is necessarily large.

Furthermore, since the base end beams are fixed at alternately opposite upper and lower positions on the sides of the base column, the range of expansion and contraction of each arm is such that when one is in an extended state, the other is in a contracted state. As a result of restricting the movement, the arm that is fitted to the proximal beam will not come off and slip out even if a stopper or the like is not provided, making it safe.

Furthermore, the sliding portion of the present invention is configured such that the inner surface of the tube serves as the sliding surface, and is not directly exposed to the outside air, so it has excellent corrosion resistance and dust resistance. That is, it exhibits various effects, such as the fact that the sliding function is less likely to be inhibited by the accumulation of dust or rust in the area.
