DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multipurpose dome having a natural turf coat on an arena surface in the dome.

[0002]

2. Description of the Related Art Official games such as the World Cup and the J-League in soccer competitions are to be played on natural grass courts. It is known that proper illuminance and sunshine hours are required for growing and maintaining this natural turf.

[0003]

However, in the conventional multipurpose dome, it is difficult to satisfy these conditions of illuminance and sunshine duration, and the above-mentioned soccer game which requires natural grass in the multipurpose dome is held. Has various problems.

In the case of a dome having an openable roof, for example, even when the roof is opened, the sunshine time is limited by a fixed roof or the like, and a similar problem remains in growing and maintaining turf. .

In some cases, a soccer game is played by temporarily bringing turf grown in a facility outside the dome into the dome, but the cost is enormous and a problem arises in terms of profitability.

Accordingly, the present invention provides a multipurpose dome having a vertically movable roof with a natural turf, which facilitates the maintenance and management of natural turf on the arena surface in the dome and does not obstruct equipment for turf management. It is an object.

[0007]

According to the present invention, in a multipurpose dome (1) having a natural turf coat on an arena surface in the dome, an upper end (2a) of a fixed roof (2) of the dome (1) is flat. And a hole portion (3) is provided,
The floor structure (5) having natural turf on its surface is sized to form a part of the roof at the hole (3) when raised, and to the outside of the fixed roof (2) A plurality of lifting device storage units (4) for raising and lowering the floor structure (5) with the wires (9) are provided, and a winch unit (8) is provided on the ground portion (4a) of the lifting device storage unit (4). A second sheave unit (10) is provided at the top (4b), and a suspension hook (12) for lifting the floor structure (5) is provided at the first sheave unit (11). , One end of the wire (9) from the winch unit (8) is constituted by a plurality of moving pulleys via guide sheaves (14a, 14b) and a second sheave unit (10) provided in the storage portion (4). Via the first sheave unit (11) that has been lifted, Is fixed to the top (4b),
Further, a control device (15) for controlling the winch unit (8) is provided.

[0008]

[Explanation of the function and effect] Since the present invention is configured as described above, when a natural turf court is required, for example, in an official soccer game, a floor structure having natural turf raised on the surface is lowered into the dome. Compete. When there is no competition, a plurality of jigs of the floor structure are slung on hanging hooks of the lifting device, and the winch unit winds up the wires via the first and second sheave units. In this case, the floor structure is configured to be kept horizontal by the control device and rise. And since it is pulled up to the hole provided at the top of the dome and constitutes a part of the roof, it is possible to secure the same illuminance and sunshine hours as on the ground without the dome, and it is easy to maintain and maintain the natural turf it can.

Further, a floor on which various events can be held is formed as a multipurpose dome inside the dome with the floor structure raised.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of a multipurpose dome 1 having a floor structure having natural turf according to the present invention. An upper end 2a of a fixed roof 2 is formed in a plane, and an upper end 2a thereof.
Is a floor structure 5 having a natural turf on its surface (approximate dimensions: 12).
0 m × 80 m), the hole 3 having the size and shape that the floor structure 5 forms a part of the roof is provided.

The dome 1 is provided with a plurality of (six in the illustrated example) lifting device housings 4 outside the fixed roof 2. Here, reference numeral 3a indicates a part of a structural member constituting the dome, and reference numeral 9 indicates a wire that moves up and down the floor structure 5.

FIG. 2 is a schematic cross-sectional view of the dome 1. The hoisting device housing 4 provided outside the fixed roof 2 indicated by a chain line.
Referring to FIG. 3, which is a perspective view showing a main part of the lifting device,
The winch unit 8 is installed on the ground part 4a,
b, a second sheave unit 10 composed of a plurality of constant sheaves is provided, and one end of a wire 9 from the winch unit 8 is connected to guide sheaves 14a, 14b and a second sheave unit 10 provided in the storage portion 4. Through a first sheave unit 11 composed of a plurality of moving sheaves, and is fixed to the uppermost portion 4b of the lifting device housing portion 4.

Further, the first sheave unit 11 is provided with a suspending hook 12, and the suspending hook 12 is provided with a wire of a suspending jig 13 provided on the floor structure 5 (the figure shows a state of ascending and descending). Is slung.

The interior of the multi-purpose dome 1 has a stand 6 having an inclined floor for watching a game, and a floor structure 5 having natural turf is raised to the upper part 2b of the fixed roof 2 to hold an event. A floor 7 is formed.

The winch unit 8 includes an electric circuit 8a.
Are connected to the control device 15, and other winch units (not shown) are also connected to the control device 15 by electric circuits.

Incidentally, when the position is raised to the position A of the dashed line, it is stopped by a signal from the control device 15 and is fixed by a fixing device (not shown) to prevent an accidental drop.

Therefore, the competition using the natural turf court,
For example, when used in an official soccer match, the upper part 2a of the fixed roof 2 is illuminated from the position of the hole 3 in the same manner as the ground, and the fixing device of the natural turf on the floor structure that has been maintained and maintained is released. Then, a signal is sent from the control device to each winch to drive the winch, and the floor structure 5 is lowered and lowered to the ground to form a natural grass court on the arena surface, thereby enabling a game.

When the maintenance and management of the turf is necessary, or when an event in which the natural turf is not used is held in the dome, the floor structure 5 is raised and fixed on the upper part 2a of the fixed roof 2 with the fixing device. If so, the floor 7 can be used for an event. In the event of an event or the like, the wire 9 of the lifting device remains wound up and does not become a hindrance. In the case of a competition, after the floor structure 5 is lowered, the wire of the hanging jig of the floor structure is pulled from the hanging hook. If the wire 13 is removed and the wire 9 is wound up, the first sheave unit 11 will not be in the way.

[0020]

The present invention has the following advantages because it is configured as described above.

(1) The natural grass court provided in the multipurpose dome can be grown and maintained in the same manner as an outdoor natural grass.

(2) In the case of an event that does not require natural turf as a multipurpose dome, a floor without turf can be easily obtained.

(3) Therefore, a multipurpose dome can be obtained which can be widely used from a soccer official game requiring a natural grass court to a general event.
