Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to aerial observatories installed at amusement parks, observation areas, etc., and in particular, a method for raising and lowering the observatory using air pressure. This is about an aerial observatory.

[Conventional technology]

Various observation decks are installed in amusement parks, observation areas, etc., and among these, so-called aerial observation decks in which an observation room is installed in the air are known.

These aerial observation decks include those in which the observation room is fixedly installed high up in the air, and those in which the observation room itself is provided so that it can be raised and lowered.

In the case of aerial observatories where the observation deck is fixedly installed high up in the air, an elevator or stairs are installed from the ground to the observation deck, especially if the observation deck is installed at a fairly high position. , viewers exclusively use the elevator to go up and down to the observation deck.

On the other hand, in the case of an aerial observatory in which the observation room itself is provided so that it can be raised and lowered, the observation room has an elevating mechanism similar to an elevator.

That is, the elevating mechanism used in conventional aerial observatories involves attaching, for example, a strong wire rope to the ceiling of the elevator room or observation room, and suspending the elevator room or observation room with this wire rope.
The wire rope is hoisted up and down using the rotational force of a powerful motor to raise and lower elevator rooms and observation rooms.

[Problem that the invention attempts to solve]

However, as mentioned above, the elevating mechanism of conventional aerial observatories is such that the elevator room and observation room are suspended using wire ropes, and the wire ropes are hoisted up and down while being raised and lowered. If the wire rope breaks in the elevator room or observation room at a high location, there is a risk of a major accident.

In particular, a large tension is constantly acting on the wire rope due to the weight of elevator rooms and observation decks, and the strength of the wire rope tends to decrease due to creep and fatigue caused by this tension. In this case, there is a risk that the wire rope may be damaged, and the wire rope may break due to these flaws.

In addition, if the elevator room or observation room is located at a high position and the lifting mechanism fails, the elevator room or observation room will be suspended at a high position, and it will not be easy to rescue the elevator room or observation room. Another drawback is that a large force is applied to parts related to hoisting and lowering during hoisting or lowering of a wire rope, and this large force tends to cause failures.

This idea was devised to solve the problems mentioned above, and its purpose is to suspend the observation room with a wire rope like the conventional elevating mechanism. Unlike the mechanism, the observation room is raised and lowered using air pressure, which prevents the observation room from suddenly falling due to wire rope breakage when using conventional wire ropes, and mid-hanging due to failure of the lifting mechanism. To provide an aerial observatory that can prevent the above situation from occurring and allow the observatory to be raised and lowered more safely.

[Means for solving problems]

In order to achieve the above objectives, this invention installs a hollow body in the vertical direction, forms the side circumferential surface of the hollow body with a transparent material, arranges an observation room inside the hollow body so that it can be raised and lowered, and An entrance to the observation room can be opened and closed on the side surface of the lower part of the body, an air outlet is provided on the side surface slightly below the observation room at the highest position, and an air outlet is provided on the side surface slightly below the observation room at the lowest position. It has a configuration in which an air inlet is provided on the side circumferential surface, and an air injector is provided for forcibly injecting air into the interior of the hollow body through the air inlet.

Here, as a preferred embodiment, the air inlet may be provided so as to be openable and closable, and the auxiliary air outlet may be provided on the side peripheral surface below the air outlet so as to be openable and closable.

[Effect]

This invention having the above configuration operates as follows.

In other words, when raising the observation room, an air injection machine is operated to flow air from the air inlet into the space below the observation room inside the hollow body, and the pressure of the inflow air raises the observation room. is gradually pushed upward, and the observation room rises inside the hollow body. When the observation room reaches its highest position, the air that had been pushing up the observation room until then is exhausted from the air outlet provided on the side surface of the hollow body, so the observation room cannot rise any further. , it stops at that position.

The next time the observation room is lowered, the operation of the air injection machine will be stopped. The pressurized air inside the hollow body below the observation room leaks little by little from the gap between the observation room and the inner peripheral surface of the hollow body, so the observation room gradually descends inside the hollow body due to its own weight. .

〔Example〕

This invention will be described in more detail below based on embodiments shown in the drawings.

Here, FIG. 1 is a schematic longitudinal sectional view of the aerial observatory.

In the figure, an aerial observatory 1 includes a hollow body 2 installed vertically, an observation room 3 disposed in an interior 2a of the hollow body 2 that can be raised and lowered, and an air pressure supplying air pressure for raising and lowering the observation room 3. It consists of 4 incoming machines. The aerial observation deck 1 has a structure in which the observation room 3 moves up and down, and in particular, the observation room 3 descends very slowly, allowing viewers to view the surrounding scenery from inside the observation room 3, which descends slowly. I'm starting to be able to do it.

The hollow body 2 is installed substantially vertically, and has various external shapes, such as a cylindrical shape or a polygonal tube shape. A roof 5 is provided at the upper end of the hollow body 2, and a bottom plate 6 is laid at the lower end, that is, the hollow body 2 is placed on the bottom plate 6. The hollow body 2 is formed by the roof 5 and the bottom plate 6.
The interior 2a of is kept in a sealed state.

The side peripheral surface 2b of the hollow body 2 is made of a transparent material, so that the outside scenery can be seen from the inside 2a of the hollow body 2. Although it is preferable that the entire side circumferential surface 2b of the hollow body 2 is made of a transparent material, a part of the side circumferential surface 2b of the hollow body 2 may be provided with a frame material made of an opaque material.

At the lower part of the hollow body 2, an entrance 7 is provided for entering and exiting the observation room 3 in the interior 2a. Doorway 7
A door 8 that can be opened and closed is attached to the. door 8
is provided with a key 9, so that the door 8 cannot be opened when the observation room 3 is raised.
Further, this door 8 is made airtight to prevent air from leaking from the closed doorway 7.

The observation room 3 that moves up and down inside 2a of the hollow body 2 includes a base plate 3a, columns 3b, support arms 3c, and guide rollers 3d.
It is composed of etc. The planar shape of the base plate 3a is similar to the cross-sectional shape of the inside of the hollow body 2, and chairs and tables for viewers are installed on the base plate 3a, and the viewers can sit on the base plate 3a. You can sit on the upper chair and look out at the scenery outside.

The observation room 3 has a base plate 3a that constitutes the floor of the observation room 3.
A pillar 3b is erected at the center of the pillar 3b, and a plurality of support arms 3c are arranged radially in the horizontal direction from the upper end of the pillar 3b. In addition, the side peripheral surface 2b
A plurality of guide rollers 3d are attached to the portions in contact with the inner surface of the base plate 3a, that is, below the peripheral edge of the base plate 3a and at the tips of the support arms 3c, and slide between the viewing room 3 and the inner surface of the side circumferential surface 2b of the hollow body 2. is becoming smoother. And observation room 3 consisting of the above structure
is prevented from tilting in the interior 2a of the hollow body 2 by a plurality of support arms 3c and a base plate 3a, which are arranged radially in the horizontal direction from the upper end of the support 3b.

An air outlet 1 is provided on the upper side peripheral surface 2b of the hollow body 2.
A plurality of 0s are provided. The location where the air outlet 10 is provided is located slightly below the position of the observation room 3 that has risen to the top.

The air outlet 10 is an outlet for discharging the air that has raised the observation room 3 from the inside 2a of the hollow body 2 to the outside. This prevents the observation room 3 from rising further, and by continuing to inject air, the observation room 3 can be maintained at the highest position. In this way, the air outlet 10 has a safety function and a function of maintaining the observation room 3 at the highest position on the condition that air is continued to be supplied.

An air inlet 1 is provided on the side peripheral surface 2b at the lower end of the hollow body 2.
1 is provided. The location where the air inlet 11 is provided is located further below the position of the observation room 3 that has descended to the lowest position.

The air inlet 11 is connected to the hollow body 2 below the observation room 3 in order to obtain air pressure for raising the observation room 3.
The observation room 3 can be raised by the air pressure of the air flowing in from the air inlet 11. An opening/closing lid 11a is attached to the air inlet 11 to prevent air from flowing out from the air inlet 11 when the inflow of air is stopped.

One end of the air injection machine 4 is connected to the air inlet 11 . The air injector 4 is a device that forcibly injects air into the interior 2a of the hollow body 2 through the air inlet 11, and uses, for example, a blower.

At the center of the bottom plate 6 of the inside 2a of the hollow body 2 is a pedestal 1.
2 is installed, and this pedestal 12 is provided with a spring 13. The pedestal 12 and the spring 13 serve to maintain a space for a pressure chamber below the observation room 3 to push up the observation room 3. As a result, air can be forced into the lower part of the observation room 3 from the air injection machine 4 through the air inlet 11, and the observation room 3 can be raised using the press-in air.

Further, a plurality of auxiliary air outlets 14 are provided on the side peripheral surface 2b of the hollow body 2 below the air outlet 10, and the auxiliary air outlet 14 has an opening/closing lid 14.
a is installed. The auxiliary air outlet 14 is used when it is desired to quickly lower the ascending observation room 3. That is, the opening/closing lid 1 of the auxiliary air outlet 14
By opening 4a, air can also be discharged from the auxiliary air outlet 14, and the pressure of the air below the observation room 3 can be quickly weakened, making it possible to speed up the descent of the observation room 3.

FIG. 2 is a schematic plan view of a plurality of aerial observatories connected together.

In the drawing, three aerial observatories 1 are installed in the shape of an equilateral triangle, and each aerial observatory 1 is connected by a connecting member 15. By having a plurality of observation rooms 3 floating in the air inside the platform 1 2a, a spectacular image can be given.

Next, the effects based on the configuration of the above embodiment will be explained below.

First, the key 9 of the door 8 of the entrance 7 is turned, the door 8 is opened, and the viewer is admitted into the observation room 3 located at the lowest position. After that, the door 8 of the entrance/exit 7 is closed and locked 9 to prevent the door 8 of the entrance/exit 7 from being opened.

Next, the air injection machine 4 is operated. When the air injection machine 4 operates, air is forced to flow into the interior 2a of the hollow body 2 through the air inlet 11 to which one end of the air injection machine 4 is connected. If this operation is continued, the pressure of the air in the space below the observation room 3 will gradually increase, and the air pressure will gradually push the observation room 3 upward, causing the observation room 3 to ascend inside 2a of the hollow body 2. I'll go. At this time, the observation room 3 is pushed up only by air pressure, so when the observation room 3 starts to rise, the observation room 3 starts to rise smoothly due to the cushioning action of the air pressure.

The observation room 3 that has been raised inside 2a of the hollow body 2 rises to the highest position. When the observation room 3 reaches the highest position, the air that had been pushing up the observation room 3 until then is discharged from the air outlet 10 provided on the side circumferential surface 2b of the hollow body 2. It will not be able to rise and will remain in that position.

When it is desired to keep the observation room 3 at the highest position for a long time, the air injection machine 4 continues to operate to continue supplying the amount of air discharged from the air outlet 10.

On the other hand, when lowering the observation room 3 at the highest position, the operation of the air injection machine 4 is stopped, and if necessary, the opening/closing cover 11a of the air inlet 11 is closed, and air is discharged from the air inlet 11. prevent When the operation of the air injection machine 4 is stopped, the air in the lower interior 2a of the observation room 3 leaks little by little from the gap between the observation room 3 and the side peripheral surface 2b. Therefore, the observation room 3 descends very slowly by an amount corresponding to the decrease in air pressure. Since this descent is continuous and extremely gradual, viewers in the observation room 3 can enjoy the scenery around the aerial observation deck 1 through the side surface 2b made of transparent material from the observation room 3 in a relaxed mood. You can fully enjoy it.

When the observation room 3 descends to the lowest position, the base plate 3a of the observation room 3 is supported by the spring 13 provided below, and the impact is absorbed along with the air pressure below the observation room 3. , when the viewer reaches the lowest position, the viewer will not feel any impact from landing. After arriving, the door 8 is opened by turning the key 9, and the viewers inside the observation room 3 are let out.

It should be noted that this invention is not limited to the above embodiments, and it goes without saying that various modifications can be made without departing from the spirit of this invention. For example, in the above embodiment, the auxiliary air outlet 14 is provided, but it may be omitted if necessary.

[Effect of idea]

As is clear from the above description, according to the aerial observatory according to this invention, the observatory can be raised and lowered using air pressure, and the conventional wire rope and lifting mechanism used therein are completely unnecessary. It can be made unnecessary.

For this reason, it is possible to prevent various troubles that occur when using conventional wire ropes, such as sudden falls in the observation room due to wire ropes breaking, and mid-suspension situations due to malfunctions in the lifting mechanism. This allows the observation room to be moved up and down more safely.

Moreover, since the observation room is raised and lowered using air pressure, the air pressure acts as a cushion and can absorb the shock when the observation room starts and stops going up and down, compared to conventional methods that use wire ropes. It is possible to smoothly start and stop the raising and lowering of the observation room, and the viewers in the observation room do not experience any discomfort.

In addition, the lowering of the observation room can be accomplished by discharging the pneumatic air supporting the observation room, and no special energy is required for the lowering, contributing to cost reduction. Furthermore, by discharging the air little by little, the observation room can be lowered extremely slowly, and the observation time during the descent can be maintained for a long time.

This has extremely practical and beneficial effects, such as allowing viewers inside the observation room to enjoy the aerial view from the transparent material through the side circumferential surface of the hollow body without feeling any anxiety during the ascent and descent of the observation room. It is something that plays.
