BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an event facility such as a stadium or a multipurpose hall, and more particularly to an event facility in which artificial grass can be laid according to the event.

[0002]

2. Description of the Related Art In recent years, in a stadium that uses a so-called ground such as soil or concrete, turf material made of synthetic resin is used as a mat material in order to enable a competition using a turf ground. Artificial grass that has been planted in the area is being temporarily laid on a ground such as soil or concrete as a substitute for natural grass.

When the artificial grass is temporarily laid on a ground such as soil or concrete, conventionally, for example,
Artificial grass with a width of 3 to 4 m and the required length is wound in advance in a roll shape, and the worker carries it to the artificial grass laying area and unrolls it to unroll it, so that the grass is sequentially spread. The method is adopted.

[0004]

However, in the case of the above-mentioned conventional method, a large number of rolls wound with artificial turf are unwound by human naval tactics. There is a problem that the seams between grasses must be processed so that there is no danger of players getting caught in their feet, and therefore, it takes a lot of labor and time even when laying work in a relatively narrow area. There is. Further, the work of unrolling the roll of the artificial turf may be carried out by using a tractor or the like, but since the work of processing the joint is still manual work, there is a limit to the improvement in efficiency. Furthermore, since the above-mentioned many artificial turf is not always used, it is necessary to wind it in a roll and store it when not in use, but there is no space to store it in the ground, so a dedicated storage place is required. It must be secured and there is a problem in terms of space.

Therefore, the present invention makes it possible to efficiently lay artificial grass with a small number of people without the need to process seams, and to provide an event facility which is advantageous in terms of storage space for artificial grass. It is what

When laying artificial turf, first, the tilt frame of the bleaching seat, in which the artificial turf laying device is stored, is pivotally displaced upward, or the entire bleacher is pivotally displaced vertically. In this state, the artificial grass laying device is moved out of the space below the bleachers and moved to one end of the artificial grass laying area. Then, the artificial grass laying device is moved toward the other end of the artificial grass laying area. At this time, the drum is rotated along with the movement of the movable carriage, and the artificial turf wound on the drum is unwound. Thus, when the artificial grass laying device arrives at the other end of the artificial grass laying area, the artificial grass is spread over the entire artificial grass laying area. In addition, the artificial grass laying device after laying the artificial grass or when not laying the artificial grass stores the space below the bleaching seat as a storage location.

[0009]

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

FIGS. 1 to 3 show an embodiment of the present invention, in which a part of the bleachers 1 located in a portion facing a predetermined artificial grass laying area in a stadium as an event facility is vertically moved. The artificial turf laying device 3 which is configured to be rotatable to the turf and is capable of laying the artificial turf 2 evenly in the artificial turf laying area is provided in a wide space 4 formed below the bleachers 1. The configuration is such that it is stored so that it can be taken in and out.

More specifically, a large number of seats 5 are arranged in a multi-stage manner on the tilt frame 6, and the upper end of the tilt frame 6 is
A bleaching seat 1 is connected to a floor 7 which is a corridor erected on a supporting frame 8 by a hinge pin 9, and the bleaching seat 1 is installed on at least one side of an artificial grass laying area of a required area. A wide space 4 is formed below the bleachers 1 so that the artificial grass laying device 3 can be stored in the space 4, and the vicinity of the inner upper end of the inclined frame 6 and the inner tip of the floor 7 are provided. An opening A is formed in the front side by extending the hydraulic cylinder 10 interposed between the lower part and the vicinity of the upper part to raise the lower end side of the tilted frame 6 in a horizontal state.
The artificial grass laying device 3 is allowed to enter and exit through the. Reference numeral 11 denotes a temporary support material for supporting the load of the tilt frame 6.

The artificial grass laying device 3 has the following structure. That is, the pedestal 1 is mounted on each of the left and right moving carriages 14 each having a plurality of urethane rubber tires 12 and driven by the driving motor 13.
5 is erected, and a large drum 16 having a required diameter and width dimension (axial length) is provided between the upper surfaces of the left and right mounts 15.
Are rotatably supported via bearings 17, respectively, so that a large-sized single piece of artificial grass 2 corresponding to the artificial grass installation area is wound around the drum 16, and both end surfaces of the drum 16 are The internal gears 19 are respectively provided, and the pinion gears 20 meshed with the internal gears 19 are
The drum 16 is attached to the shaft of the rotary drive motor 21 installed on the outer side of the pedestal 15 and the pinion gear 20 is rotated by the drive of the rotary drive motor 21 to rotate the drum 16 integrally with the internal gear 19. The artificial turf 2 wound around 16 is unwound and laid. Further, as a mechanism for holding one end of the artificial grass 2 on the drum 16 when winding the laid artificial grass 2 on the drum 16,
For example, clamp claws 18 are provided at required widthwise intervals on the peripheral wall portion of the drum 16 so that the electric jacks 22 installed inside the drum 16 can be moved in and out from the outer peripheral surface of the drum 16 in the radial direction. The tip end of the winding start of the artificial grass 2 can be clamped by the clamp claw 18.

In the present invention, the artificial turf laying device 3 is used to uniformly lay a single artificial turf 2 in a predetermined artificial turf laying area on the ground 23.
Therefore, for example, the size of the artificial turf 2 has a width of 50 to 7
Assuming that the length is 0 m and the length is 80 to 100 m, the drum 16
Is set to have a diameter of 3 m and a width of 70 m or more.

When laying the artificial turf 2 in a predetermined artificial turf laying area on the ground 23, first, the artificial turf 2 is wound around the drum 16 and stored in the space 4 below the seat 1. The artificial turf laying device 3 that has been placed is carried out from the space 4 below the grandstand 1 and moved to the artificial turf laying area. In this case, seat 1
The tilting frame 6 of the hydraulic cylinder 10 as shown in FIG.
After the opening operation is performed to open the opening A to form the opening A, the traveling drive motors 13 of the left and right moving carriages 14 are driven to move the moving carriage 14 forward from the storage position, and the drum 16 is moved to one end of the artificial grass laying area. Try to align it with the point.

After that, the left and right traveling drive motors 13 are synchronously driven so that the moving carriage 14 travels toward the other end point of the artificial grass laying area, and at the same time, the left and right rotary drive motors 21 are synchronously driven. The drum 16 is rotated in the required direction. At this time, the traveling speed of the moving carriage 14 is controlled to match the rotation speed of the drum 16. When the artificial turf 2 is unwound from the drum 16 and the end of the artificial turf 2 is laid on the ground 23 as the mobile carriage 14 travels, the tilted frame 6 of the bleacher 1 is installed.
3 from the state of FIG. 3 to the state of FIG. 1 to press the end of the artificial turf 2 at the lower end of the tilting frame 6 or press the end of the artificial turf 2 by other means to make the artificial turf Two
Is sequentially unwound from the drum 16 and sequentially laid, whereby the artificial turf 2 is moved to the artificial turf laying area when the movable carriage 14 travels linearly and reaches the other end of the artificial turf laying area. It will be completely spread out. After the laying work is completed, the movable carriage 14 is run in the opposite direction to the position of the bleachers 1, and the artificial grass laying device 3 is stored in the space 4 below.

In the above description, since the drum 16 of the artificial turf laying device 3 is arranged so that the single piece of the artificial turf 2 having a size corresponding to the artificial turf laying area is wound, the movable trolley 14 is made to travel. By rewinding and rotating,
The artificial grass 2 can be laid all over the entire artificial grass installation area. Therefore, unlike the conventional method, the work of treating the seam is not necessary and the workers involved are also unnecessary, so that the artificial grass 2 can be laid in a short time by a small number of people. Further, the artificial grass laying device 3 after laying the artificial grass 2 can store the space 4 below the bleachers 1 as a storage place, which is extremely advantageous in terms of space.

On the other hand, when removing the laid artificial turf 2, the artificial turf laying device 3 is used as in the case of laying.
Move out from the lower space 4 of the bleachers 1 and first move the carriage 14
Is unwound at the other end of the artificial grass laying area and moved to the final position. Next, attach the end of the artificial grass 2 to the drum 16
After holding the end of the artificial turf 2 to the drum 16 such as by clamping with the clamp claw 18 on the outer peripheral surface of the, the moving carriage 14 is run backward in the direction of the viewing seat 1 while rotating the drum 16 in the winding direction. To do so. As a result, the wide artificial grass 2 can be removed while being evenly wound around the drum 16. After the winding is completed, it is stored in the space 4 below the viewing seat 1.

Next, FIG. 4 shows another embodiment of the present invention. In the above embodiment, the tilt frame 6 of the bleachers 1 is used.
In place of the type in which only the tilting frame 6 is rotated, the upper end of the inclined frame 6 is fixed to the floor 7, and the lower end of the support frame 8 is rotated in the front-rear direction by the hinge pin 9 so that the entire spectator seat 1 is hydraulically operated. The shortening operation of 10 allows the lower end of the tilted frame 6 to be turned horizontally so that the opening A is formed, and the wide space 4 and the pit of the required depth below the viewing seat 1. 24 is formed so that the artificial grass laying device 3 can be moved up and down by a lifter (a pantograph lifter in the figure) 25 installed in the pit 24 so as to be stored in the space 4. .

The embodiment shown in FIG. 4 is applied when the height of the seat 1 is too small to store the artificial grass laying device 3 as shown in FIG. It is possible to dig a pit 24 in the space 4 and to equip the pit 24 with a lifter 25 so that the artificial turf laying device 3 in which the artificial turf 2 is wound around the drum 16 is sunk in the pit 24 for storage. As a result, the height of the seat 1 is low and the space 4 below
Even in a case where the artificial grass laying device 3 cannot be directly stored inside, it is possible to cope with it. When the artificial turf laying device 3 is stored, the bleachers 1 are entirely rotated as shown by the chain double-dashed line to ensure a height that does not interfere with the artificial turf laying device 3 and then The laying device 3 is carried into the lower space 4, placed on the lifter 25, and the lifter 25 is lowered to allow the artificial turf laying device 3 to be dropped into the pit 24 by a required amount. Since the storage height of the device 3 can be suppressed to the height in the space 4 below the bleaching seat 1, after the storage, the hydraulic cylinder 10 is extended to move the bleaching seat 1 to the state shown by the solid line in FIG. To Since the artificial grass 2 is laid, the same applies when the artificial grass laying device 3 is taken out from the stored state.

The present invention is not limited to the above-described embodiment. For example, in the embodiment shown in FIGS. 1 to 3, the floor portion 7 of the grandstand 1 is erected by the support frame 8. However, the floor portion 7 may be a floor portion that serves as a walkway in the front of an existing (fixed) bleacher, and the upper end portion of the inclined frame 6 may be rotatably connected to the floor portion. The rotation driving method of the drum 16 of the laying apparatus 3 and the traveling driving method of the moving carriage 14 may be a method other than those shown and described, or the moving carriage 14 may be a non-driving type that pushes and pulls. Further, in the example, the case of the stadium as an event facility is shown, but the same can be done for other facilities such as a multipurpose hall,
Needless to say, various changes can be made without departing from the scope of the present invention.

[0021]

As described above, according to the event facility of the present invention, a large opening is formed in the front when the inclined frame in which a large number of seats are arranged in a multi-stage manner is raised to be in a horizontal state. A wide space is formed under the seat, and a long drum capable of rotatably driving a large-sized single piece of artificial grass corresponding to the artificial grass installation area can be rotatably driven. Since the artificial turf laying device thus obtained can be put in and taken out through the opening, while moving the artificial turf laying device as a whole from one end point to the other end point of the artificial turf laying area, By rotating the drum and unwinding the artificial grass that has been wound around the drum, it is possible to spread the artificial grass on the artificial grass laying area without performing seam treatment. The artificial turf can be removed by moving the artificial turf laying device in the opposite direction while winding the artificial turf around the turf, so that a large number of people can use it for a short time without requiring much labor. The artificial turf can be laid and removed at the same time, and the artificial turf laying device can be stored in the space below the bleachers, so the space can be used effectively and space is extremely limited. Moreover, the height of the pedestal can be lowered by making the bleaching seat rotatable in the vertical direction as a whole and forming a pit in the space below it so that the artificial grass laying device can move up and down in the pit. Even in the bleachers, it is possible to store the artificial turf laying device in the space below it, which is an excellent effect.
