<< Effect of this embodiment >>
According to the present embodiment, since the face materials 5A and 5B are made of a flexible and deformable material, it becomes easy to make the appearance of the screen 2 conform to the form of the frame structure 4, and the screen. It is possible to improve the degree of freedom in design and appearance design in 2. In particular, if the frame structure 4 is made of a round pipe, the shape of the frame structure 4 can be formed relatively freely. Further, since the face materials 5A and 5B can be mainly composed of foam or the like, the frame structure 4 is formed of a round pipe, which makes it easy to reduce the weight of the whole. Further, since the outer surface of the screen 2, in other words, the outer surface of the booth 1 is made of a flexible and deformable material, it is possible to alleviate the feeling of hardness when touched or collided, and the appearance is also good. An elegant screen 2 having a soft curved surface or the like can be easily realized.

In particular, the round pipes 7A1 to 7C1 can be bent in any direction, facilitating the formation of various curved surfaces, and providing a screen having an unprecedented excellent appearance.

Further, since the frame structure 4 includes a plurality of columns 6A to 6F and frames 7A to 7C laid horizontally between the columns 6A to 6F, the columns 6A to 6F and the frames 7A to The portion other than 7C is composed of only the face materials 5A and 5B. Therefore, the portion is relatively easily deformed, which not only gives the user softness but also provides various conveniences. That is, in the case of such a configuration, even if the edge of the top plate 3 is arranged close to the screen 2, the face materials 5A and 5B are temporarily provided as shown in the imaginary line of FIG. By deforming it, various optional members 195 can be attached to the edge of the top plate 3. That is, in this embodiment, the optional mounting area 3A is provided at the edge portion of the top plate 3 that abuts or is close to the face materials 5A and 5B, and the screen 3 corresponding to the optional mounting area 3A. The portion has a structure in which none of the columns 6A to 6F and the frames 7A to 7C are arranged so as to allow the face materials 5A and 5B to be deformed in the thickness direction.

Further, in the booth 1 of this embodiment, the frame structure 4 has an upper frame 7A arranged between the upper ends 6Aa to 6F of the columns 6A to 6F and 6Ab to 6Fb between the lower ends of the columns 6A to 6F. The lower frame 7B arranged in the center and the intermediate frame 7C arranged between the intermediate portions 6Ac to 6Fc near the lower ends of the columns 6A to 6F are provided, and the intermediate frame 7C and the lower frame 7C are provided. Since the transparent window region 4a in which the face materials 5A and 5B do not exist is formed between the frame 7B and the frame 7, it is possible to detect from the outside whether or not there is a user inside.

Further, the columns 6A to 6F are provided with vertical pipes 6A1 to 6F1 in an upright posture and horizontal pipes 6A2 to 6F2 and 6A3 to 6F3 rigidly connected to both upper and lower ends of the vertical pipes 6A1 to 6F1, respectively. The upper frame 7A is formed by erection of the frame pipes 7A1 between the horizontal pipes 6A2 to 6F2 provided at the upper ends 6Aa to 6F of the respective columns 6A to 6F, and each of the above. Since the lower frame 7B is formed by erection of the frame pipe 7B1 between the horizontal pipes 6A3 to 6F3 provided at the upper ends 6Ab to 6Fb of the columns 6A to 6, each column 6A to 6F and each frame 7A The same connection structure can be adopted for the connection points with 7C, and the configuration can be simplified.

Since the screen 2 has the face materials 5A and 5B stretched on both the inner and outer surfaces of the frame structure 4, not only can the appearance of the inside and outside of the booth 1 be adjusted, but also options as described above. It is also possible to obtain the advantage that even if the face material 5B on the inner surface side is deformed when the member 195 is attached, the face material 5A on the outer surface side is not affected.
