DETAILED DESCRIPTION

With reference to the drawings, the present disclosure will be described in further detail by providing exemplary embodiments and specific examples hereinafter. However, the present disclosure is not limited to these exemplary embodiments and specific examples.

In the description with reference to the following drawings, the drawings are schematic. Thus, it should be noted that the ratios or the like of dimensions differ from actual ratios, and illustrations of unnecessary portions for the description are omitted as appropriate for facilitating understanding.

First Exemplary Embodiment

(1) Overall Structure of Booth

FIG. 1 is a partially cutaway perspective view of an inner configuration of a booth 1 according to the present exemplary embodiment. FIG. 2 is a partially sectional front view of the inner configuration of the booth 1. Hereinafter, the overall structure of the booth 1 will be described with reference to the figures.

As illustrated in FIGS. 1 and 2, the booth 1 includes a foundation portion 2 disposed above an installation surface FL, a floor board 3 disposed on the foundation portion 2, a side-wall panel 4 disposed on the foundation portion 2 in an upright manner, a top panel 5 disposed on the side-wall panel 4, four casters 6 disposed at a lower portion of the foundation portion 2, and four fasteners 7 disposed at a lower portion of the foundation portion 2 and near the respective casters 6.

The foundation portion 2 is formed by joining four beam members 21 to each other so as to form a rectangular shape corresponding to a bottom shape of the booth 1, and the foundation portion 2 is formed of, for example, rectangular steel tubes.

The floor board 3 is in contact with and supported by a floor supporting member 22 protruding inward relative to the foundation portion 2. For example, the floor board 3 is formed of structural plywood, which is a wooden board member, on which a floor mat is layered.

The side-wall panel 4 is formed of a first side-wall panel 41 that forms a backside wall, a second side-wall panel 42 and a third side-wall panel 43 that form a right-side wall and a left-side wall, respectively, and a fourth side-wall panel 44 that forms a front-side wall. The fourth side-wall panel 44 has an opening 44a that is to be an entrance, and the opening 44a is fitted with a door 45. In the present exemplary embodiment, the door 45 is a sliding door.

The top panel 5 is fixed to an upper end portion of the side-wall panel 4 so as to close an upper opening formed by the side-wall panel 4, and the top panel 5 is formed of, for example, structural plywood that is a wooden board member. The upper opening formed by the side-wall panel 4 may remain open without installing the top panel 5.

The casters 6 are disposed at four corners of the lower portion of the foundation portion 2. When installing the booth 1, which has been assembled in a factory or the like, at an installation site, the booth 1 is transported by a truck or the like while placed on the truck bed and, at the installation site, the booth 1 is installed on the installation surface FL by moving the booth 1 on the casters 6.

The fasteners 7 are adjustable in height, and the booth 1 is immovably fixed to the installation surface FL in such a manner that, between the installation surface FL and the foundation portion 2, the casters 6 are suspended above the installation surface FL.

In the booth 1 configured as described above, a desk 11 and a chair 12 are placed as illustrated in FIG. 1 so that a user may work or study while sitting on the chair 12 and using the desk 11.

The desk 11 is formed of a top 11a and a pair of legs 11b supporting the top 11a. The top 11a is disposed above the floor board 3 in such a manner that a back-end edge 11ab of the top 11a is in contact with a side wall (the second side-wall panel 42) of the four side-wall panels 41, 42, 43, and 44.

In contrast, the chair 12 is movable on the floor board 3 within a predetermined range.

(2) Floor Structure

FIGS. 3A and 3B are a sectional plan view and a partial sectional front view, respectively, of the inner configuration of the booth 1. FIGS. 4A and 4B are a sectional plan view and a partial sectional front view, respectively, of the inner configuration of the booth 1 in a state in which a smaller floor board 31 of the floor board 3 divided into two floor boards is removed. FIGS. 5A and 5B are sectional plan views of the inner configuration of the booth 1 in a state in which the smaller floor board 31 of the floor board 3 divided into two floor boards is removed and the location of a larger floor board 32 is changed.

Hereinafter, a floor structure of the booth 1 will be described with reference to the figures.

As illustrated in FIGS. 3A and 3B, the floor board 3 is unequally divided into two floor boards that are the smaller floor board 31 and the larger floor board 32 arranged in the longitudinal direction of the floor surface. The smaller floor board 31 of the divided floor board 3 is removable. As illustrated in FIG. 3A, the floor board 3 is divided, outside a range of motion of the chair 12, into the smaller floor board 31 and the larger floor board 32 (see Region R enclosed by a chain double-dashed line in FIG. 3A).

As illustrated in FIGS. 4A and 4B, two fasteners 7A and 7B of the four fasteners 7 disposed at the lower portion the foundation portion 2 and near the respective casters 6 become accessible from inside the booth 1 (see arrows in FIGS. 4A and 4B) when the smaller floor board 31 of the floor board 3 divided into two floor boards as described above is removed.

In addition, in the floor surface, a space enabling the remaining larger floor board 32 to move in the longitudinal direction of the floor surface is created (see L in FIG. 4B). In this state, the desk 11 and the chair 12 are placed on the larger floor board 32. The smaller floor board 31 to be removed is positioned close to the door 45. Thus, the fasteners 7 are accessible from inside the booth 1 without removing the desk 11 and the chair 12 from the booth 1.

As illustrated in FIGS. 5A and 5B, the other fasteners 7C and 7D also become accessible from inside the booth 1 when the larger floor board 32 is moved to the space created by removing the smaller floor board 31, by a distance of substantially half the length (L/2) of the space in the longitudinal direction of the floor board 3, while the desk 11 and the chair 12 remain placed on the larger floor board 32.

In this state, the chair 12 may be moved toward the first side-wall panel 41 (see FIG. 5A) or toward the fourth side-wall panel 44 (see FIG. 5B) on the larger floor board 32, and each of the fasteners 7C and 7D may be easily accessed from inside the booth 1 without removing the desk 11 and the chair 12 from the booth 1.

The larger floor board 32 that has been moved to the space created by removing the smaller floor board 31, even at the position of the larger floor board 32 after being moved to the space, is in contact with and supported by the floor supporting member 22 protruding inward relative to the foundation portion 2. Thus, sagging of the floor surface is suppressed.

The fasteners 7 may be known adjusters. The installation height of the booth 1 from the installation surface FL is vertically adjustable by accessing each of the fasteners 7 from an access space, which is created by changing the location of the larger floor board 32, and by rotating an adjustment bolt 7a of each of the fasteners 7 (see FIG. 12).

Modifications

FIGS. 6A and 6B are a sectional plan view and a partial sectional front view, respectively, of an inner configuration of a booth 1 according to a modification. FIGS. 7A and 7B are sectional plan views of the inner configuration of the booth 1 in a state in which smaller floor boards 31A of a floor board 3A divided into two types of floor boards are removed and the locations of the desk 11 and the chair 12 are changed. FIGS. 8A and 8B are sectional plan views of other examples of division of the floor board 3A of the booth 1 according to modifications.

As illustrated in FIGS. 6A and 6B, the floor board 3A of the booth 1 according to a modification is divided, outside the range of motion of the chair 12 (see Region R enclosed by a chain double-dashed line in FIG. 6A), into a larger floor board 32A and the triangular smaller floor boards 31A at four corners of the floor board 3A. The smaller floor boards 31A are removable.

The desk 11 and the chair 12 are placed on the larger floor board 32A. Four sides of the larger floor board 32A are in contact with and supported by the floor supporting member 22 protruding inward relative to the foundation portion 2. Thus, sagging of the floor surface is suppressed. Similarly, two sides of each of the triangular smaller floor boards 31A are in contact with and supported by the floor supporting member 22.

In the floor board 3A divided into portions as described above, mating surfaces (dividing positions) of the triangular smaller floor boards 31A and the octagonal larger floor board 32A are, as illustrated in FIGS. 6A and 6B, less likely to be positioned within the range of motion of the chair 12 (see Region R enclosed by a chain double-dashed line in FIG. 6A). Thus, sagging of the floor surface is suppressed.

As illustrated in FIGS. 7A and 7B, all four of the fasteners 7A, 7B, 7C, and 7D disposed at the lower portion of the foundation portion 2 and near the respective casters 6 become accessible from inside the booth 1 (see arrows in FIGS. 7A and 7B) when the smaller floor boards 31A of the floor board 3A divided into two types of floor boards are removed and the locations of the desk 11 and the chair 12 are changed on the larger floor board 32A (see Arrows X in FIGS. 7A and 7B), without removing the desk 11 and the chair 12 from the booth 1.

The shape of the smaller floor boards 31A that are formed by dividing the floor board 3A into portions at four corners of the floor surface is not limited to a triangular shape and may be a quadrangular shape as illustrated in FIG. 8A or a sectoral shape as illustrated in FIG. 8B.

All four of the fasteners 7A, 7B, 7C, and 7D become accessible from inside the booth 1 when the smaller floor boards 31A of the floor board 3A divided into two types of floor boards are removed and the locations of the desk 11 and the chair 12 are changed on the larger floor board 32A.

Second Exemplary Embodiment

FIG. 9 is a partially cutaway perspective view of an inner configuration of a booth 1A according to the present exemplary embodiment. FIGS. 10A and 10B are a sectional plan view and a partial sectional front view, respectively, of the inner configuration of the booth 1A. FIGS. 11A and 11B are sectional plan views of the inner configuration of the booth 1A in a state in which the smaller floor board 31 of the floor board 3 divided into two floor boards is removed and the location of the larger floor board 32 is changed. FIG. 12 illustrates installation of one of the fasteners 7 and a corresponding one of anti-toppling boards 8.

Components that are the same as those of the first exemplary embodiment are denoted by the same references and detailed description of the components is omitted here.

As illustrated in FIGS. 9, 10A, and 10B, the booth 1A includes the foundation portion 2 disposed above the installation surface FL, the floor board 3 disposed on the foundation portion 2, the side-wall panel 4 disposed on the foundation portion 2 in an upright manner, the top panel 5 disposed on the side-wall panel 4, four casters 6 disposed at the lower portion of the foundation portion 2, four fasteners 7 disposed at the lower portion of the foundation portion 2 and near the respective casters 6, and the anti-toppling boards 8.

In the booth 1A, the fasteners 7 are disposed on the installation surface FL with a corresponding one of the rectangular anti-toppling boards 8 interposed therebetween and disposed on the right and left sides of the booth 1A. It is difficult to access the fasteners 7 from outside the booth 1A and to adjust the installation height of the booth 1A because each of the fasteners 7, as illustrated in FIG. 12, is installed on the installation surface FL with the corresponding anti-toppling board 8 interposed therebetween in a narrow space (see A in FIG. 12) between the installation surface FL and the foundation portion 2 of the booth 1A.

In the booth 1A according to the present exemplary embodiment, the floor board 3 is unequally divided into two floor boards that are the smaller floor board 31 and the larger floor board 32 arranged in the longitudinal direction of the floor surface. The smaller floor board 31 of the divided floor board 3 is removable.

As illustrated in FIGS. 11A and 11B, the fasteners 7A, 7B, 7C, and 7D become accessible (see arrows in FIGS. 11A and 11B) when the smaller floor board 31 of the floor board 3 divided into two floor boards as described above is removed and the larger floor board 32 is moved to the space created by removing the smaller floor board 31, by a distance of substantially half the length (L/2) of the space in the longitudinal direction of the floor board 3, while the desk 11 and the chair 12 remain placed on the larger floor board 32 as illustrated in FIGS. 11A and 11B.

Thus, even when each of the fasteners 7 is installed on the installation surface FL with the corresponding anti-toppling board 8 interposed therebetween in the narrow space between the installation surface FL and the foundation portion 2 of the booth 1A, the installation height of the booth 1A from the installation surface FL is vertically adjustable by accessing the fasteners 7 from inside the booth 1A and by rotating the adjustment bolts 7a.

As in the modifications of the first exemplary embodiment, the floor board 3 is divided, outside the range of motion of the chair 12, into the larger floor board 32A and the smaller floor boards 31A that are triangular, quadrangular, or sectoral at four corners of the floor surface. The smaller floor boards 31A may be removable.
