Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a heliport used for takeoff and landing of a helicopter (hereinafter, abbreviated as a helicopter).

[0002]

2. Description of the Related Art As is well known, helicopters take off and land at a heliport, which is a dedicated place. This heliport has conventionally been able to obtain a predetermined ground effect, that is, at the time of helicopter takeoff and landing. Buoyancy is required to be obtained by wind pressure from the propeller of the helicopter toward the upper surface of the heliport.

Therefore, the heliport is formed so that the upper surface thereof can receive the above-mentioned wind pressure, that is, the helipad has a width enough to secure a necessary pressure receiving area. It is needless to say that the helipad is provided directly on the ground. The same applies to the case where the floor is provided on the top floor of a building other than the ground, for example, the rooftop of a high-rise building.

However, when providing a heliport on the ground, it is easy to secure a necessary area structurally.
When provided on the rooftop of a high-rise building, the heliport may exceed the size of the rooftop.

[0005] When a heliport exceeding the size of the rooftop is provided on the rooftop of a high-rise building, the skyline may be impaired, that is, the beauty of the upper space viewed from the ground may be impaired. However, this heliport is considered to be a part of a high-rise building, and there is a problem that it becomes a ground for a height restriction in the high-rise building.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a heliport that is particularly suitable for being provided on a rooftop of a high-rise building. .

[0007]

In order to achieve the above object, a heliport according to the present invention is basically provided with a fixed support standing on the top floor of a building and a central support at the upper end of the fixed support. A deck which is connected to a pivot portion and is set to be foldable in a mountain shape at the central pivot portion, and is disposed between both ends of the deck and the top floor of the building to form a pair on the left and right. A link leg, each of which has a tip connected to the pair of link legs and a drive cylinder which is fixed to the top floor of the building and has a pair of left and right drive cylinders, has a predetermined area. It is assumed that the main deck has a main deck and a sub-deck which is connected to the main deck so as to be able to appear and disappear and has a predetermined area, and the sub-deck is set to be slidable with respect to the main deck by an appropriate driving means.

[0008] More specifically, the main deck and the sub-deck comprise a frame portion formed in a truss structure, and a plate portion connected to the upper end of the frame portion and formed in a flash structure. It is assumed that the section is set so as to be able to move up and down with respect to the frame section by a suitable elevating means.

Preferably, the main deck and the sub-deck have handrails at the peripheral ends so as to be able to undulate.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a heliport according to an embodiment of the present invention; FIG. It has a deck 2, a link leg 3, and a drive cylinder 4. In the illustrated embodiment, a handrail 5 is provided on the deck 2 so as to be able to undulate.

The fixed support column 1 is erected on a building, that is, a roof floor r as the top floor of a high-rise building A, and supports the deck 2 from below.
This is an element for determining the height position of the deck 2 when the heliport is used and in a folded state.

Therefore, it is sufficient that the fixed column 1 is formed to have a predetermined strength and length in the axial direction. For example, when the main column 11 and the stay 12 are each formed of a steel pipe, This is advantageous in that the overall weight can be reduced.

The number of the fixed supports 1 is four (four in the illustrated example), and consideration is given to support the deck 2 in a stable state (see FIG. 3).

The deck 2 has a central support portion 2a having a fixed support 1
, That is, the upper end of the main column 11 forming the fixed column 1, and is set so as to be folded in two at the central pivot portion 2a so as to be folded into a mountain shape (FIG. 1).

In the present invention, the deck 2 comprises a main deck 21 having a predetermined area, and a sub-deck 22 having a predetermined area connected to the main deck 21 so as to be able to protrude and retract. The sub-deck 22 is set to be slidable with respect to the main deck 21 by appropriate driving means.

The main deck 21 is connected to the central pivot 2
a, the sub-deck 22 is formed into a two-piece body in each of the two-piece main decks 21, and each of the sub-decks 22 is formed as a two-piece body. The main deck 21 is slidably connected to the main deck 21.

Further, in the illustrated embodiment, the main deck 21 and the sub-deck 22 are respectively provided with frame portions 21a, 22a formed in a truss structure, and are connected to the upper ends of the frame portions 21a, 22a, respectively, to be flushed. It consists of plate portions 21b and 22b formed in a structure.

Further, while the plate portion 22b of the sub-deck 22 is continuously provided so as to be integrated with the frame portion 22a, the plate portion 21b of the main deck 21 is appropriately moved up and down with respect to the frame portion 21a. It is set so that it can be raised and lowered.

When the plate portion 21b of the main deck 21 is lifted by the elevating means, the sub-deck 22 can smoothly enter and exit the main deck 21 without interfering with the main deck 21, that is, can be loaded and unloaded. .

The main deck 21 of the sub-deck 22
2 is a vertical direction in FIG. 2, and a direction along a direction in which the folding line set at the central pivot 2 a is a horizontal direction in FIG. 3, that is, the roof floor r of the high-rise building A. The longitudinal direction of the main deck 21 is taken into consideration so that the deck 2 can be folded even if the sub-deck 22 is pulled out from the main deck 21.

As described above, the deck 2 is connected to the central pivot 2a.
When the heliport is not used, the deck can be folded and the gable roof can be provided on the rooftop r of the high-rise building A when the heliport is not used. The provision of the heliport does not cause a sense of incongruity, that is, does not cause deterioration of the skyline.

In the deck 2, the sub-deck 22
Is formed so as to be able to expand and contract according to the manner in which it is protruded and retracted from the main deck 21, so that a compact folded state can be realized at the time of the above-mentioned folding.

Since the deck 2 is formed by the frame portions 21a and 22a formed in the truss structure and the plate portions 21b and 22b formed in the flash structure, a predetermined ground effect on the deck 2 is ensured. Thus, it is possible to reduce the total weight while making it possible to further reduce the size of the lifting / lowering means and the driving means.

By the way, the driving means is a sub-deck 2
No particular limitation is required as long as the slide 2 is slidable with respect to the main deck 21, but the illustrated embodiment has a hydraulic cylinder 23 (see FIG. 2).

The hydraulic cylinder 23 has, for example, a main deck 2 whose one end is set to a fixed side.
The other end is connected to the frame portion 22a of the sub-deck 22 which is set on the movable side, and when the extension operation is performed, the sub-deck 22 is pushed out of the main deck 21 and when the contraction operation is performed. The sub-deck 22 is set to be drawn into the main deck 21.

Although not shown, the hydraulic cylinder 23 is connected to a hydraulic supply / discharge mechanism installed on the rooftop r or the like of the high-rise building A, and is set so as to be expanded and contracted by the hydraulic supply / discharge mechanism. Have been.

The driving means may be composed of a combination of a sprocket and a chain. However, in consideration of maintenance such as rust prevention and securing of driving force, the driving means has the hydraulic cylinder 23 described above. It can be said that it is preferably formed in a hydraulic drive structure.

The elevating means does not need to be particularly limited as long as the plate part 21b can be moved up and down with respect to the frame part 21a in the main deck 21. As with the means, it is preferable to set a hydraulic drive structure having a hydraulic cylinder 24 (see FIG. 3).

When the lifting means is set to a hydraulic drive structure having a hydraulic cylinder 24, it is possible to use a hydraulic supply / discharge mechanism for supplying / discharging hydraulic pressure to / from the hydraulic cylinder 23 in the drive means. This is advantageous.

The link legs 3 are arranged between both ends of the deck 2 and the rooftop r of the high-rise building A, which is a building, and are set so as to be paired on the left and right. If so, it is formed in the form of a frame (FIG. 3).
reference).

In the illustrated embodiment, the link legs 3 are positioned so as to be disposed between the fixed columns 1, and a plurality of members, ie, two members each in the front-rear direction and the left-right direction. The four decks are arranged so that the deck 2 can be stably folded and used stably.

The link leg 3 has an upper member 31 whose upper end is rotatably connected to the deck 2 and a lower end which has a rooftop r.
And a lower member 32 rotatably connected to the
The lower end of the upper member 31 and the upper end of the lower member 32 are rotatably connected.

When the link legs 3 are extended in a pair on the left and right, the link legs 3 function as so-called columns to support the deck 2 together with the fixed columns 1 from below. Each link leg 3 is set to be folded in a so-called inward direction when folded.

It should be noted that the link legs 3 in the illustrated embodiment are set so as to exhibit a so-called upward spreading mode when they are completely extended in a pair at the left and right. However, instead of this, it may be set so as to exhibit an aspect of standing upright with the same width, or to exhibit an aspect of diverging.

The drive cylinder 4 is disposed between the link leg 3 and the rooftop r, and is set so as to form a pair on the left and right. In the illustrated embodiment, the drive cylinder 4 is set to a telescope type. It consists of a hydraulic cylinder.

The drive cylinder 4 has a distal end connected to the lower member 32 of the link leg 3 and a base end fixed to the rooftop r.
The lower member 32 is pulled down, and the lower member 32 is pushed up during the extension operation 3.

The drive cylinder 4 is used for driving the hydraulic cylinder 23 as the above-mentioned drive means.
Is connected to a hydraulic supply / discharge mechanism installed in the apparatus and the like, and is set so as to be expanded and contracted by the hydraulic supply / discharge mechanism.

The handrail 5 is provided for security when a person enters the deck 2. When the deck 2 is formed large enough to easily secure a predetermined ground effect, it is not always necessary. It does not have to be provided.

In the illustrated embodiment, the handrail 5 is formed to have a predetermined size by extruding the peripheral ends of the main deck 21 and the sub-deck 22, that is, the sub-deck 22 from the inside of the main deck 21. It is arranged so that it can be raised and lowered around the periphery of the deck 2.

In the illustrated embodiment, the handrail 5 is raised and lowered by manual operation. Alternatively, the handrail 5 may be raised and lowered by using power. It is said that the helicopter is maintained in a defeated state when the helicopter arrives or departs from the helicopter.

Although the heliport according to the present invention basically suffices to be formed as described above, in the illustrated embodiment, the deck 2 can be used with the link leg 3 extended. The following considerations have been made for maintaining the link legs 3 in the folded state and maintaining the unused state of the deck 2.

That is, the link legs 3 are extended to maintain the deck 2 in a usable state, as shown in FIG.
2 is brought into contact with the upper end of the pillow portion a disposed on the rooftop r of the high-rise building A, which is the fixed side, so that the link leg 3 slightly passes the so-called dead point but does not further turn over. I am careful.

As shown in FIG. 1, the lower end of the deck 2 abuts on the upper end when the link leg 3 is bent to maintain the deck 2 in a folded state as shown in FIG. So that it can be supported from below.

Therefore, by forming and using the pillow portion a, it is possible to maintain the link leg 3 in the extended state without complicating the structure of the link leg 3 and complicating the control of the drive cylinder 4, and to maintain the link leg 3 in the extended state. This makes it possible to prevent the legs 3 from being inverted, and to prevent the deck 2 from being unnecessarily folded when the deck 2 is folded.

The pillow portion a is, of course, mechanically independent of the parapet p, which is a side wall connected to the rooftop r of the high-rise building A, but has sufficient mechanical strength. May be formed integrally with the parapet p.

The heliport according to the present invention formed as described above can be used by the operation procedure shown in FIG.

First, from the state shown in FIG.
Is extended to make the link leg 3 in the extended state. At this time, since the lower end of the lower member 32 of the link leg 3 is fixedly connected to the rooftop r of the high-rise building A, FIG. Thus, the upper end of the lower member 32 can be lifted.

At this time, the upper end of the upper member 31 of the link leg 3 whose lower end is connected to the upper end of the lower member 32 is connected to the so-called outer end of the deck 2 and the so-called inner end of the deck 2 That is, the central pivot 2a
Is fixedly connected to the upper end of the fixed support 1,
While the upper member 31 stands up, the deck 2
To raise the outer edge of the

When the drive cylinder 4 is extended to a predetermined stroke, as shown in FIG. 6, the lower member 32 and the upper member 31 of the link leg 3 rise and become extended. The outer end of the deck 2 is raised to the same level as the central pivot 2a, and the deck 2 is in a usable state, that is, a flat state.

At this time, in the illustrated embodiment, the lower member 32 of the link leg 3 comes into contact with the pillow portion a provided on the rooftop r of the high-rise building A and is locked. The extended state is maintained permanently.

Next, from the state shown in FIG. 6, ie, the state shown in FIG. 7, a hydraulic cylinder (not shown and not shown) as a driving means is extended to make the sub-deck 22 protrude from the main deck 21. Before the deck 2 is made to have a predetermined size, before that, a hydraulic cylinder (not shown and not shown) as an elevating means is extended to raise the plate portion 21b of the main deck 21 with respect to the frame portion 21a.

Thus, as shown in FIG. 8, a space is formed between the plate portion 21b and the frame portion 21a, and the sub-deck 22 can be pushed out smoothly without interfering with the main deck 21.

After the extrusion of the sub-deck 22 is completed, the plate portion 21b of the main deck 21 is lowered as shown in FIG.
Are so-called flush with the plate portion 22b of the sub-deck 22.

In the state where the expansion of the deck 2 is completed, that is, in the state shown in FIG. 9, the take-off and landing of the helicopter to and from the heliport can be performed. At this time, the handrail 5 is in a state where it is lying down. Put in.

When a person such as a worker or a passenger enters the deck 2, as shown in FIG. 10, the handrail 5 is erected to prevent an accident such as a fall, and
Although not shown, the traffic of the person between the rooftop r and the deck 2 is realized by an arbitrary method such as using a ramp car or a lift car traveling on the rooftop r.

[0056]

As described above, according to the present invention, since the deck can be folded into a mountain shape at the central pivot,
When the heliport is not used, the deck can be folded and the gabled roof can be provided on the rooftop of the high-rise building, so that the heliport does not cause discomfort, that is, the skyline Will not be caused.

At this time, since the deck is composed of a main deck and a sub-deck, and the sub-deck is set to be extendable and retractable so as to be protruded and retracted from the main deck, a compact folding state is realized when the deck is folded. This is advantageous in that it can be performed.

In the present invention, since the deck is formed by the frame portion formed in the truss structure and the plate portion formed in the flash structure, it is possible to easily secure a predetermined ground effect in the deck. While reducing the total weight, the drive means for moving the sub-deck with respect to the main deck and the lifting means for raising and lowering the plate part with respect to the frame part on the main deck do not increase the size of each. Become.

Further, when the deck has a handrail that can be raised and lowered, it does not hinder takeoff and landing of the helicopter to the heliport, and the safety of persons on the deck can be ensured.

As a result, according to the present invention, it is particularly suitable for installation on the rooftop of a high-rise building.
