DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] A private booth 1 according to one embodiment of the present invention will be described below with reference to Figures 1 to 14. In this embodiment, the directions of the private booth 1 are defined by arrows in each figure. As shown in Figure 1, the private booth 1 according to this embodiment is placed on the floor and used for indoor use by one person or a small number of people. The private booth 1 according to this embodiment is formed with a width dimension of 1200 mm in the left-right direction and a width dimension of 1200 mm in the front-rear direction.

[0024] 1 to 5, the private booth 1 according to this embodiment includes a peripheral wall 2 provided on three sides, a left peripheral wall 2L, a right peripheral wall 2R, and a rear peripheral wall 2B, and an opening 2a formed in the front, a door 4 provided on the peripheral wall 2 so as to be able to open and close the opening 2a, and a ceiling 5 closing an upper part of the peripheral wall 2. By closing the opening 2a of the peripheral wall 2 with the door 4, an internal space isolated from the outside is formed in the private booth 1.

[0025] In the private booth 1 according to this embodiment, as shown in Fig. 2, the inner side of the peripheral wall 2 and the door 4 are formed to open downwards. The private booth 1 is formed to open downwards without a floor board, so that the effective height of the room relative to the overall height of the booth can be secured to be large, compared to a booth with a floor board. When mass-producing the private booth 1, it is necessary to be able to install it in many spaces, and since there is a limit to how high the overall height of the private booth 1 can be increased, the configuration of this embodiment, which allows the height of the room to be as high as possible, is preferable.

[0026] In addition, since the inner side of the peripheral wall 2 and the door 4 of the private booth 1 are formed to open downwards, users do not need to climb or descend steps when entering or exiting the private booth 1. In this way, by eliminating the step between the outside and inside of the private booth 1, it is possible to enter and exit on the same level, improving the convenience of the private booth 1.

[0027] As described above, in the private booth 1 according to this embodiment, no floor members are provided on the lower part of the inner side of the peripheral wall 2 and the door 4, so that the floor members do not deform or emit abnormal noises due to the weight of the user, etc., when the private booth 1 is used. Also, in this embodiment, there is no need to provide highly rigid floor members to prevent deformation, etc., so the manufacturing costs of the private booth 1 can be reduced.

[0028] The peripheral wall 2 is provided with a plurality of casters 75 (five in this embodiment) and a plurality of ground contact members 76 (four in this embodiment) that can be rotated by the user with their hands or a tool to adjust the extension length from the underside of the peripheral wall 2 to the floor surface (see Figs. 2 and 3). In this embodiment, as shown in Figs. 7(a) and 9(b), the two ground contact members 76 provided at the rear of the private booth 1 are fixed to brackets 77 provided on the underside of the peripheral wall 2.

[0029] In this embodiment, five casters 75 are provided on the private booth 1, but the number of casters 75 is not limited as long as the private booth 1 can be moved. Similarly, the number of grounding members 76 is not limited as long as the private booth 1 can be stably installed.

[0030] The private booth 1 according to this embodiment can be changed between an immovable state in which the casters 75 are separated from the floor surface and a movable state in which the casters 75 are in contact with the floor surface. Specifically, the extension length of the ground contact member 76 from the lower surface of the peripheral wall 2 is adjusted to be greater than the extension length of the casters 75, thereby bringing the casters 75 into an immovable state in which they are separated from the floor surface. Also, the extension length of the ground contact member 76 from the lower surface of the peripheral wall 2 is adjusted to be smaller than the extension length of the casters 75, thereby bringing the casters 75 into a movable state in which they are in contact with the floor surface. In this way, the private booth 1 is provided with a plurality of casters 75 and a plurality of ground contact members 76 whose extension length relative to the floor surface can be adjusted, thereby making it possible to easily move / install the private booth 1.

[0031] As shown in Fig. 6, the peripheral wall 2, which is composed of the left peripheral wall 2L, the right peripheral wall 2R, and the rear peripheral wall 2B, includes two side panels (a left panel 20L and a right panel 20R) that face each other in the left-right direction, and a rear panel 20B that is connected to the rear ends of the two side panels 20L and 20R.

In this way, by providing the glass wool 64 inside the right peripheral wall 2R, the sound-absorbing performance of the private booth 1 is improved.

[0042] As shown in Figures 7 and 8, an outer cover plate 65 exposed to the outside is provided on the outer surface side of the right peripheral wall 2R. Specifically, as shown in Figure 10, a plurality of engaging members 65a are provided on the inner surface of the outer cover plate 65. The outer cover plate 65 is attached to the right panel 20R by engaging the engaging members 65a with engaging holes 22c opened in the front frame member 22 (similarly for the rear frame member 23).

[0043] In the private booth 1 according to this embodiment, as shown in Figures 3 to 5, a top plate 66 is attached to the right panel 20R via a bracket 66a, which is an engaging member. More specifically, as shown in Figures 7(a) and (b), the engaging portion of the bracket 66a fixed to the top plate 66 is engaged with the engaging hole 61a of the engaging member 61. As a result, the top plate 66 is attached to the inner surface of the right peripheral wall 2R.

[0044] 8(b) and 10, a support member 67 is fixed to the lower end of the right side panel 20R. A side sound insulation plate 68 is provided inside the support member 67, and the inner surface of the side sound insulation plate 68 is covered with a side covering plate 69. The side sound insulation plate 68 is disposed between the support member 67 and the side covering plate 69. As a result, the side sound insulation plate 68 is provided along the lower end of the right peripheral wall 2R such that its height position relative to the lower end can be changed, and the side sound insulation plate 68 can abut against the floor surface due to its own weight.

[0045] In this way, according to the private booth 1 of this embodiment, the size of the gap between the floor surface and the side sound insulation board 68 can be changed, which makes it possible to improve the sound insulation of the private booth 1. Also, as shown in Figures 8(b) and 9(b), in this embodiment, the side sound insulation board 68 is abutted against the floor surface by its own weight to close the gap between the right side peripheral wall 2R and the floor surface, thereby further improving the sound insulation of the private booth 1.

[0046] Next, the configuration of the rear peripheral wall 2B including the rear panel 20B will be described with reference to Figures 6 to 9 and 11.

That is, by changing the size of the gap between the floor surface and the sound insulation boards, it is possible to improve the sound insulation of the private booth 1.

[0069] The rear sound-proofing plate 36 is configured so that its relative height position at the lower end of the rear peripheral wall 2B is fixed. This makes it possible to adjust the sound insulation of the private booth 1 by adjusting the gap between the floor surface and the rear sound-proofing plate 36 to a desired size.

[0070] The side sound-proofing boards 68 are configured to be able to come into contact with the floor surface by their own weight, so that the gap between the peripheral wall and the floor surface can be blocked by the side sound-proofing boards 68, thereby improving the sound insulation of the private booth 1.

[0071] It is also possible to make the rear sound-proofing plate 36 capable of abutting against the floor surface by its own weight, and to make the height position of the side sound-proofing plate 68 adjustable. In other words, the presence or absence and size of a gap between the lower end of the peripheral wall 2 and the floor surface can be appropriately selected according to the usage mode of the private booth 1.

[0072] Moreover, according to the private booth 1 of this embodiment, a sound-proofing member 45 is provided under the door 4, and the sound-proofing member 45 is configured so that the distance from the floor surface can be changed. This makes it possible to further improve the sound insulation of the private booth 1. Also, by changing the distance between the floor surface and the sound-proofing member 45, it becomes possible to adjust the sound insulation of the private booth 1.

[0073] Furthermore, according to the private booth 1 of this embodiment, at least one of the three sound insulation plates (the two side sound insulation plates 68 and the back sound insulation plate 36) and the sound insulation member 45 is configured to have a gap between it and the floor surface. This means that the private booth 1 is not completely isolated from the outside space, making it possible to ensure the ventilation function of the private booth 1.

[0074] [Other variations] The above embodiment can be modified as appropriate as shown in the other modified examples shown below. Each modified example described in this specification may be applied in combination with other modified examples to the extent that no contradiction occurs.

[0075] In addition, the materials constituting the peripheral walls and the door are not limited to glass panels or metal panels, and materials such as wood or resin may be used. In addition, the arrangement of these may also be configured in a manner other than that of this embodiment.

[0076] The side panels constituting the private booth may be configured without the front and rear frame materials. It is also possible to configure the side panels to have only one of the front and rear frame materials. The front and / or rear frame materials constituting the side panels may be attached to the side panel main body later, or may be assembled integrally with the side panel main body in advance to complete the side panel.

[0077] The ceiling of the private booth may be configured without a front or rear ceiling frame. It may also be configured with only one of the front or rear ceiling frames. The front and / or rear ceiling frames may be attached to the main ceiling body later, or may be assembled integrally with the main ceiling body in advance to complete the ceiling.

[0078] It is also possible to configure the booth so that the front end faces of the two side panels and the front end face of the ceiling are not continuous when viewed from the front. It is also possible to configure the private booth so that it does not have a connecting member. It is also possible to configure the private booth so that it does not have casters and grounding members.
