Description

Technical Field

[0001] The present invention relates to a mobile stage structure in which a box-shaped cargo bed is configured as a gull-wing opening / closing type to be formed into a roofed stage by upward opening, and various stage facilities can be prepared for installation. In particular, the present invention relates to a multi-purpose mobile stage structure that can be used for an outdoor temporary performance stage, a mobile golf driving range by installing a net, etc., wherein a solar panel is installed on the outer wall surface of the cargo bed to secure necessary power, and at the destination, the operation of opening the box-shaped cargo bed not only forms the roofed stage, but also allows facilities such as ceiling lighting, acoustic equipment, and an electric bulletin board to be installed on the stage. Background Art

[0002] A stage is always prepared when holding events and the like in a general public square outside a theater. Usually, the stage is constructed through simple construction, and a roof, a backdrop, acoustic equipment, and a lighting device are installed on the stage. After the event ends, the stage is dismantled and recovered. In the case of temporary installation in a place with no nearby power source, it is difficult to carry out construction to distribute power from a nearby utility pole, so it is preferable to provide a power source such as a large-capacity storage battery.

[0003] On the other hand, when golf equipment is sold outdoors at golf tournaments, event festivals and the like, it is preferable to have a temporary driving range surrounded by golf nets, but temporary installation is difficult.

[0004] Conventionally, in addition to a mobile exhibition room (Patent Document 1) that uses the cargo bed of a truck, provides a movable wall to configure an exhibition room, and deploys the exhibition room by rotating the movable wall upward, there have been proposed an assembled stage device vehicle (Patent Document 2) that forms a stage at the rear of a vehicle body and foldably provides an auxiliary stage on the front side thereof, and a stage device vehicle (Patent Document 3) that provides a liftable multimedia sign board on a cargo bed.

[0006] However, using a conventional truck bed as a stage requires a roof, and a separate tent is necessary if the truck bed is used as is. Furthermore, stage equipment requires a large-capacity power supply, but using an engine generator generates noise, making it undesirable as a primary power source. In addition, the stage requires equipment such as lighting, sound equipment, and electronic display boards.Therefore, the present invention seeks a mobile stage that can be immediately moved to outdoor locations without power, easily set up as a temporary stage, and that can be prepared for installation of the necessary roof and equipment by opening the truck bed. The object of the present invention is to provide such a mobile stage structure. [Means for solving the problem]

[0007] In order to provide a cargo bed structure that addresses the above issues, the necessary considerations are as follows: Firstly, how to prepare a covered stage structure without using a tent; secondly, how to secure a large amount of electricity without relying on utility poles; and secondly, how to prepare and install the stage lighting, sound equipment, and electronic display boards that form the stage background, which will be transported on the cargo bed. The inventors have focused on the fact that in order to solve these necessary problems and to temporarily set up stage equipment in any location, firstly, 1) if the cargo bed on which the stage and stage equipment are installed is a box-shaped cargo bed, and the frame covering the box-shaped cargo bed is made of a pair of inverted L-shaped wings that open and close like gullwing doors, then by spreading and unfolding the pair of inverted L-shaped wings like wings to form a T-shape (Figures 1 and 2(a) to (b)), the top and sides of the cargo bed 100 are opened, and a covered stage 100 can be formed as is (Figure 2(b)). Next, 2) by horizontally tilting the side panels 202 surrounding the box-shaped platform outwards and spreading them out, the platform 100 can be expanded to the left and right, securing the area necessary for the stage. Furthermore, 3) by equipping the inverted L-shaped wing 201 with a lighting device 300 on the inside of its side and unfolding it into a T-shape, the lighting equipment 300 is formed on the stage ceiling formed by the wing, illuminating the stage. Additionally, by equipping the ceiling 201 of the wing with an electronic display board 400, the electronic display board 400 can be formed by unfolding it into a T-shape. Moreover, since the box-shaped platform has a wide outer wall surface, as shown in Figure 3(a), by equipping it with solar panels 501 and 502, it is possible to provide sufficient power supply without the need for power distribution from utility poles. In view of the above points of focus, the present invention aims to provide a mobile stage structure that utilizes a gull-wing opening and closing box-shaped platform structure, can be moved to any location as needed, and can instantly form a temporary stage. In a truck or other mobile vehicle, the cargo bed extending in the front-to-rear direction is box-shaped and comprises a wing 200 and a cargo bed 100, the wing 200 consists of a pair of inverted L-shaped wings 201, the short sides 201a that divide the ceiling into two are butted together, and the long sides 201b that hang down from the ceiling are extended outward and upward at a 90-degree angle from this point to form a T-shaped roof in a gull-wing style (Figure 1(a) → Figure 1(b)). On the other hand, the cargo bed 100 comprises a pair of cargo bed side plates 202, 202 that rise from both sides, and the cargo bed side plates 202, 202 are opened outward from a vertical position to a horizontal position to provide the floor surface of the cargo bed 100 with a sufficient stage floor area (Figure 1(b)). The pair of L-shaped wings 201, 201 are provided as a ceiling-mounted solar panel 501 and a side-mounted solar panel 502 (Figure 3(a)), generating the power necessary for stage lighting, while as shown in Figures 2(a) and 2(b) 、 The pair of inverted L-shaped wings 201 are equipped with lighting devices 300 on their inner side walls 201b, enabling illumination of the cargo bed 100 from the T-shaped ceiling section, and the inverted L-shaped wings 201 are equipped with an electronic display board 400 on their inner ceiling wall 201a, enabling them to be deployed in a T-shape to form a stage background. [Effects of the Invention]

[0008] According to the present invention, a mobile vehicle such as a truck is equipped with a box-shaped cargo bed that opens and closes in a gull-wing style. By opening a pair of inverted L-shaped wings outwards to form a T-shape (from Figure 1(a) to Figure 1(b)), a covered stage is formed, and various stage equipment is arranged on that stage. On the other hand, by closing the wings (from Figure 1(b) to Figure 1(a)), the stage and stage equipment can be stored and moved. Therefore, it is an excellent and suitable mobile stage for temporary installation. More specifically, as shown in Figures 2(a) and (b), lighting devices 300 are provided on the side portions 201b of the inner walls of a pair of gull-wing type inverted L-shaped wings 201 (Figure 2(a)). By unfolding the pair of L-shaped gull wings into a T-shape (Figure 2(a)→(b)), the necessary stage lighting can be provided (Figure 2(b)). In addition, an electronic display board 400 is provided on the ceiling surface of the L-shaped inner wall, so the ceiling surface of the gull-wing inner wall can form a stage background by unfolding into a T-shape. As shown in the photograph in Figure 4, the sound effect of the electronic display board 400 can be enhanced by arranging speaker equipment on both sides of the electronic display board 400. Furthermore, by tilting the side panels 202 surrounding the loading platform 100 outwards horizontally, the stage floor formed by the loading platform 100 can be extended to the left and right, which is convenient for creating a temporary golf driving range. Furthermore, in this invention, solar panels 501 and 502 are provided on the outer surfaces of the ceiling wall 201a and side wall 201b of the cargo bed wing 200, so that the power necessary for stage lighting and electrical equipment can be supplied. In other words, according to the present invention, a stage roof and stage backdrop necessary for stage equipment are formed by deploying a pair of inverted L-shaped cargo bed wings, and can be stored by closing them, making temporary installation, storage, and relocation easy.
