Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a play equipment, and more specifically, it is used in an amusement park, a kindergarten, an elementary school, etc. Playground equipment that can be crushed and expanded to play.

[Conventional technology]

Generally, there are various types of play equipment used in amusement parks, kindergartens, elementary schools, etc., from large to small. Many of these playground equipment have various tastes for children to enjoy playing.

[Problems to be solved by the device]

By the way, the play equipment described above has a problem in that its structure becomes complicated when various tastes are attempted, and conversely, a simple structure lacks unexpectedness and freshness.

Therefore, the present invention has been proposed in view of the above problems, and an object of the present invention is to provide an entertaining play equipment having a simple structure and having surprisingness and freshness.

[Means for Solving the Problems]

The technical means for achieving the above object in the present invention is to arrange a plurality of inflatable and inflatable air bags, each of which is arranged in a predetermined arrangement and communicates with each other through an air supply valve and an exhaust valve. And a first sensor which is provided for each air bag and which detects that one air bag is crushed and the internal air is discharged through the exhaust valve, and a detection signal from the first sensor. Based on this, a random circuit that randomly selects any air bag other than the crushed air bag and opens the air supply valve of the air bag, and a random circuit that is provided for each air bag and that outputs the random circuit And a second sensor for detecting that air is filled in the air bag that is inflated when the air supply valve is opened, and the supply of the inflated air bag based on the detection signal from the second sensor. Air supply valve closed that outputs an output signal that closes the air valve Is that which is provided a road.

[Action]

In the play equipment according to the present invention, when one air bag body is crushed, the internal air is discharged through the exhaust valve, and this is detected by the first sensor. Based on the detection signal of the first sensor, an arbitrary air bag other than the air bag crushed by the random circuit is randomly selected, and the air supply valve of the air bag is opened by the output of the random circuit. . Here, since each air bladder communicates with the connecting portion via the air supply valve and the exhaust valve, air moves inside the air bladder selected by the random circuit through the air supply valve. The air bag body inflows and inflates. Then, the second sensor detects that the inside of the air bag is filled with air, and closes the air supply valve of the air bag based on the detection signal of the second sensor. As a result, the inflated air bladder is randomly transferred to another air bladder, and by repeating this in sequence, many air bladder bodies are crushed or inflated to play.

In the above description, it is assumed that the air bag body (D ₁ ) that is crushed as shown in FIG. 18 is used as a reference to proceed only in the direction shown by the broken line arrow A in the figure. However, assuming all directions around the crushed bladder,
That is, for example, as shown in FIG. 19, the air bag (D
₁₃ ) (hatched in the figure) as a reference and eight air bags (D ₇ ) (D ₈ ) (D ₉ ) (D ₁₂ ) adjacent to this
When (D ₁₄ ) (D ₁₇ ) (D ₁₈ ) (D ₁₉ ) is taken into consideration, as shown in FIG. 18, an area consisting of four air bags is added in the forward direction indicated by arrow A and added by arrow B.

At this time, it is necessary to select which of the areas (a), (b), (c), and (d) in the directions A, B, C, and D to proceed, for example, the area (a) in the forward direction indicated by the arrow A. If the probability of advancing to the area (b) in the backward direction indicated by the arrow B is decreased and the probability of advancing to the areas (c) and (d) in the left and right directions indicated by the arrows C and D is set to an intermediate value, Good. The above operation is performed by the air bag (D

In the above description, the case of randomly selecting from the compressed air bag and the adjacent air bag has been described.
This is one example, and it is possible to randomly select an air bag in a pattern other than the above, and the random circuit (1) randomly selects any air bag other than the crushed air bag. To do. At this time, in the random circuit (1), it is necessary to associate the numbers generated by random numbers with the coordinates set for all the air bags.

Finally, the air supply valve closed circuit (2) is connected to the input side thereof with the second sensors (F ₁ ) (F ₂ ) ... Of the air bags (D ₁ ) (D ₂ ) ... Each air bag (D ₁ )

A description will be given based on the flowcharts of FIGS. 18, 18 and 20. Note that the following description will be made in the case where one area consisting of four air bags is set as shown in FIG. 18 and the vehicle moves in the forward direction indicated by arrow A.

First, when the player crushes the air bag (D ₁ ) at the start position from the state shown in FIG. 1 and FIG. 18 by using the hand or the whole body, as shown in FIG. D
₁ inside _air) is discharged an exhaust valve which opens under pressure to (B ₁₎ connecting portion via a (C), the exhaust valve when it is almost completely discharged (B ₁₎ is closed. At this time, all the air supply valves (A ₁ ) (A ₂ ) ... and the exhaust valves (B 2

Is added to the air amount v of the connecting portion (C), the air pressure in the connecting portion (C) increases.

On the other hand, the first sensor (E ₁ ) detects when the internal air of the air bag (D ₁ ) is almost completely discharged, and the detection signal (S ₁ ) is input to the random circuit (1). Then the random circuit (1) operates on the basis of the detection signal of the first sensor _{(E 1) (S 1),} collapsed air bag _{(D 1)} and adjacent air bag _(D 2) (D ₆ )
For the area (a) composed of (D ₇ ), the random numbers generated as described above and the air bag (D ₂ ) (D ₆ ) (D ₇ ).

Then, the air supply valve (A ₂ ) of the air bag body (D ₂ ) selected by the output (S ₃ ) of the random circuit (1) is opened, and the connecting portion is connected via this air supply valve (A ₂ ). The high-pressure air in (C) is caused to flow into the air bag body (D ₂ ). When the air bag body (D ₂ ) is inflated and the inside thereof is almost completely filled with air, the second sensor (F ₂ ) detects the time point, and the detection signal of the second sensor (F ₂ ). The air supply valve closed circuit (2) is operated based on (S ₂ ), and the air supply valve (D ₂ ) of the air bag body (D ₂ ) expanded by the output (S ₄ ) of the air supply valve closed circuit (2) ( A ₂ ) is occluded.

As a result, the inflated air bladder has moved from the start position to any adjacent position, and the above-described operation is repeated by further crushing the air bladder (D ₂ ) (D ₃ ). Thus, the air bag (D ₁ ) (D ₂ )
By repeatedly crushing the next air bag (D ₂ ) that expands to crush the air bag several times, it finally reaches the goal position, and the air bag (D ₂₅ ) at that goal position is reached. )
End by inflating.
