Inflatable Stage

Abstract

This invention provides an inflatable stage that is easy to set up and has a structure that expands using air pressure, allowing for the selection of floor hardness and material according to the application. [Solution] The structure includes a pneumatic frame section 1 that inflates by air injection, and this frame section is arranged in a ring-like or polygonal shape on the outer perimeter, thereby defining a stage area inside for the user to enter. The floor section 2 within the area, which supports the user's weight, can use an air mat with a drop-stitch structure that is highly portable, or it can be configured to lay existing joint mats or the like according to the characteristics of the sport.

Description

Technical Field

[0001] The present invention relates to a stage having a structure that expands by air pressure, and more particularly to an inflatable stage that improves the ease of installation and removal, safety, and portability, and allows the selection of the floor material according to the application.

Background Art

[0002] Conventionally, stage or ring structures used in martial arts, sports competitions, performances, etc. generally have an assembled structure composed of a steel frame, wooden floorboards, columns, etc. While these have high durability and stability, they have the problems of requiring a large number of personnel and time for installation and removal, and high transportation costs.

[0003] In addition, pneumatic structures (such as air play equipment) that have become popular in recent years are too soft overall and the feet sink in, so they have an unsuitable aspect as a stage for full-scale competitions and performances.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The problem to be solved by the present invention is to provide a stage structure that can flexibly combine optimal floor materials such as a high-rigidity air floor or a commercially available joint mat according to the purpose of use and budget, while utilizing a pneumatic outer frame (frame) structure that is easy to install and remove.

Means for Solving the Problems

[0005] To solve the above problems, the inflatable stage of the present invention includes a pneumatic frame portion that expands by air injection, and the stage area is defined inside by arranging the frame portion in an annular or polygonal shape, and a floor member is arranged in the stage area.

[0006] As described in claim 2, the floor member may be a pneumatic structure having a double-wall structure (drop-stitch structure) in which opposing surface materials are joined internally by a connecting material. This makes it possible to achieve a plate-like rigidity when in use while remaining compact during transport.

[0007] Furthermore, as described in claim 3, the floor member may be configured by laying down a plate-like member made of resin, rubber, or wood (for example, a joint mat). This makes it possible to utilize existing mat assets or to construct a stage at a lower cost. [Effects of the Invention]

[0008] This invention provides the following effects. 1. Because the outer frame is pneumatic, the stage structure can be assembled quickly by a small number of people. 2. By adopting a "drop-stitch air floor" as the base, it becomes an all-in-one stage with excellent portability. 3. By using "joint mats" or similar materials for the floor, it becomes possible to flexibly accommodate sports requiring a harder surface or events where cost reduction is desired.

[0011] The inflatable stage of this invention is mainly composed of a "pneumatic frame section" that forms the outer perimeter and a "floor section" that is positioned inside it.

[0012] The pneumatic frame is formed from an airtight sheet such as PVC tarpaulin and inflates by pumping in air, forming a circular, square, or polygonal enclosure. This frame also functions as a bumper to prevent users from falling off the stage. Alternatively, metal or high-strength resin D-rings, eyelets, hooks, and other connecting hardware may be firmly fixed (or embedded) to the top or sides of the frame via welded patches or sewn belts. This makes it possible to extend boxing ring ropes or MMA (mixed martial arts) cage nets, creating a full-fledged competition environment. Example 1: Air Floor Type

[0013] This configuration uses a pneumatic mat with a drop-stitch structure (double-wall structure) as the floor. The frame and floor may be integrally welded together, or they may be detachably connected with strong hook-and-loop fasteners or belts. This configuration is ideal for mobile performances and outdoor events because the entire structure can be folded into a small size. Example 2: Separate floor type

[0014] This configuration uses commercially available interlocking mats (such as EVA resin mats), plywood (wooden boards), or laminated versions thereof as the floor. The pneumatic frame is installed on the ground, and the mats are laid out to fit the space inside the frame. In this case, it is desirable to install "retaining tabs (flaps)" or "connecting hook-and-loop fasteners" on the lower inside of the frame to prevent the mats from shifting. This configuration is suitable for martial arts, dance, and other activities where precise grip and firmness underfoot are required. [Explanation of Symbols]
