Problems to be Solved by the Invention

[0005] By the way, in the deck unit described in Patent Document 1, various forces are more likely to be applied to the portion corresponding to the contour of the floor surface (hereinafter referred to as the outer edge portion) than to the inner region of the floor surface (the region surrounded by the outer edge portion).

[Figure 7] This is a perspective view of an office laid out using a unit system according to one embodiment of the present invention. [Modes for carrying out the invention]

[0012] [Unit System] A unit system 1 according to Embodiment 1 of the present invention will be described with reference to Figures 1 to 4.

[0013] Figure 1 is a perspective view of Unit System 1. The upper part of Figure 1 is a perspective view of Unit System 1 with its rear and right side facing forward, and the lower part of Figure 1 is a perspective view of Unit System 1 with its left side and front facing forward. Figure 2 is a three-view drawing of Unit System 1.

[0014] In Figure 2, a front view is shown in the lower left, a top view in the upper left, and a right side view in the lower right. In Figure 2, the floor frame 11, wall frame 12, ceiling frame 13, spacer 16, leg 113, floor frame 21, spacer 26, and leg 213 of the unit system 1 are shown, and the illustration of other components is omitted.

[0015] Figure 3 is an enlarged arrow view of a part of the cross-section along the line A-A' attached to the plan view of Figure 2. The upper figure of Figure 3 is an enlarged cross-sectional view corresponding to the area A shown in Figure 2, and the lower figure of Figure 3 is an enlarged cross-sectional view corresponding to the area B shown in Figure 2.

[0016] The upper figure of Figure 4 is an enlarged cross-sectional view of the area C shown in the upper figure of Figure 3, and the lower figure of Figure 4 is an enlarged cross-sectional view of the area D shown in the lower figure of Figure 3.

[0017] In this embodiment, when assuming six rectangular planes surrounding the unit system 1, the circumscribed surfaces of the wood panel 153 and the glass panel 151 are respectively called the front and back surfaces of the unit system 1, and the circumscribed surfaces of the floor frames 11, 21 and the ceiling frame 13 are respectively called the bottom and top surfaces of the unit system 1 (see Figure 1). Also, when looking at the circumscribed surface of the wood panel 153 which is the front surface from the positive z-axis direction, the side surface located on the right side and the side surface located on the left side are respectively called the right side surface and the left side surface. Therefore, as described in the explanation of Figure 2, each of the lower left figure, the upper left figure, and the lower right figure in Figure 2 is respectively a front view, a plan view, and a right side view.

[0018] Note that for the orthogonal coordinate system attached to Figure 2, a plane parallel to the floor surface on which the unit system 1 is installed is defined as the zx plane, and the upward direction among the directions perpendicular to the floor surface is defined as the positive y-axis direction. Note that in Figure 2, the illustration of the floor surface is omitted. Also, in the zx plane, the direction from the space unit 10 to the deck unit 20 (the direction from the left side surface to the right side surface of the unit system 1) is defined as the positive x-axis direction, and the positive z-axis direction is defined so as to form a right-handed orthogonal coordinate system together with the positive x-axis direction and the positive y-axis direction. The positive z-axis direction is the direction from the back surface to the front surface of the unit system 1. Also, the orthogonal coordinate systems attached to Figures 1, 3, and 4 are the same orthogonal coordinate system as the orthogonal coordinate system attached to Figure 2.

[0019] As shown in FIGS. 1 and 2, the unit system 1 includes a space unit 10, a deck unit 20, and furniture 30.

[0020] The unit system 1 of the present embodiment includes one space unit 10 and one deck unit 20. The space unit 10 and the deck unit 20 are adjacent to each other.

[0021] However, in one aspect of the unit system 1, the number of each of the space unit 10 and the deck unit 20 provided is not limited to one and may be plural. Also, when one aspect of the unit system 1 includes at least one space unit 10 and at least one deck unit 20, any one of the at least one space units and any one of the at least one deck units may be adjacent to each other.

[0022] <Space unit> The space unit 10 includes a three-dimensional frame including a floor frame 11, a wall frame 12, and a ceiling frame 13. This three-dimensional frame defines the three-dimensional space existing on the floor surface as an internal space. Note that each of the floor frame 11, the wall frame 12, and the ceiling frame 13 defines the lower, side, and upper sides of the internal space, respectively. The floor frame 11 is an example of the first floor frame.

[0023] In addition to the three-dimensional frame, the space unit 10 further includes a floor board 14 and a plurality of spacers 16. The floor board 14 and the spacers 16 will be described after the three-dimensional frame.

[0024] (Floor frame and ceiling frame) As shown in Figures 1 and 2, in this embodiment, a three-dimensional frame of a rounded cube is employed, with the floor frame 11 and ceiling frame 13, which have a rounded square shape in plan view, serving as the upper and lower base surfaces, respectively. Therefore, in this embodiment, the shape of the internal space defined by the three-dimensional frame is a rounded cube.

[0025] The size of the space unit 10 is not limited and can be determined as appropriate depending on the application. In this embodiment, the length of one side of the rounded square floor frame 11 and ceiling frame 13 is set to 2400 mm.

[0026] However, the plan view shapes of the floor frame 11 and ceiling frame 13 in the three-dimensional frame (the shapes obtained when viewed from a direction perpendicular to the upper and lower base surfaces) are not limited to these and can be determined as appropriate. The shape of the three-dimensional frame may be, for example, a rectangular prism in which the plan view shapes of the floor frame 11 defining the upper base surface and the ceiling frame 13 defining the lower base surface are rectangular. Also, the plan view shapes of the floor frame 11 and ceiling frame 13 are not limited to a quadrilateral shape, but may be a polygon with any number of angles. Note that rectangle and rectangular shape are higher concepts than square and square shape, respectively, and polygon and polygon shape are higher concepts than rectangle and rectangular shape, respectively. Similarly, rectangular prism and rectangular prism shape are higher concepts than cube and cuboid shape, respectively.

[0027] In the following, polygons and rounded polygons will be collectively referred to as polygonal shapes. Similarly, in three-dimensional forms, for example, cuboids and rounded cuboids will be collectively referred to as cuboidal shapes. In this embodiment, the floor frame 11, wall frame 12, and ceiling frame 13 that constitute the three-dimensional frame are each made of hollow metal square pipes, manufactured by forming square pipes with a rounded quadrilateral cross-section into a closed annular rounded square. That is, each of the floor frame 11, wall frame 12, and ceiling frame 13 is a closed annular member. Therefore, in each of the floor frame 11, wall frame 12, and ceiling frame 13, the straight sections connecting the rounded corners may be slightly curved or distorted due to the manufacturing process. The expressions with "shape" attached, such as polygonal shapes and cuboidal shapes, used in this embodiment refer to deformations of shape due to the manufacturing process, and include deformations within tolerances. The same applies to the floor frame 21 of the deck unit 20, which will be described later.

[0028] As mentioned above, the space unit 10 and the deck unit 20 are adjacent to each other. Therefore, in order to reduce the gap between the space unit 10 and the deck unit 20 that may occur when they are adjacent, it is preferable that the plan view shapes of the floor frame 11 and the ceiling frame 13 in the three-dimensional frame include parts made up of straight lines (i.e., edges).

[0029] In this embodiment, the floor frame 11 is provided with a plurality of legs 113.

[0030] Each leg portion 113 is located in an inner region (one aspect of the first inner region) surrounded by the inner edge of the floor frame 11 when the floor frame 11 is viewed from above, and is fixed to the floor frame 11. In the plan view of Figure 2, the floorboard 14, which will be described later, is not shown. Therefore, although the floor frame 11 is not visible due to the overlapping ceiling frame 13, the inner region surrounded by the inner edge of the floor frame 11 and the leg portions 113 located in the inner region and fixed to the inner edge of the floor frame 11 are visible. In the plan view of Figure 2, the reference numeral 11 is shown in parentheses along with reference numeral 13 for the floor frame 11 that is hidden from view by the ceiling frame 13. Also, the spacer 16, which will be described later, is visible in the plan view of Figure 2, similar to the leg portions 113.

[0031] As shown in the plan view of Figure 2, four legs 113 are provided for each of the four straight sections that make up the four sides of the floor frame 11.

[0032] As can be seen from the upper part of Figure 3 (an enlarged cross-sectional view of area A shown in the front view of Figure 2), the floor frame 11 of this embodiment comprises a lower frame 11a, an upper frame 11b, and leg portions 113. The lower frame 11a and the upper frame 11b are welded to each other. As mentioned above, the floor frame 11 is a hollow metal square pipe, and is an annular member formed by shaping a square pipe with a rounded rectangular cross-section into a closed annular rounded square. More specifically, each of the lower frame 11a and the upper frame 11b is a hollow metal square pipe, and is an annular member formed by shaping a square pipe with a rounded rectangular cross-section into a closed annular rounded square.

[0033] The upper frame 11b is a frame for housing the floorboard 14, which will be described later, in the inner region. Therefore, when comparing the thickness of the upper frame 11b (size in the y-axis direction) with the thickness of the floorboard 14 (size in the y-axis direction), the upper frame 11b is thicker.

[0034] The lower frame 11a is a frame that surrounds all the legs 113 when the legs 113 are provided to the floor frame 11. The thickness of the lower frame 11a (size in the y-axis direction) is about the same as the thickness of the fixing part 1131 (size in the y-axis direction), which will be described later.

[0035] Each leg portion 113 is equipped with a fixing portion 1131, a screw-type adjustable leg 1132, and a nut 1133 (see the upper diagram in Figure 3).

[0036] The fixing portion 1131 is made of channel steel. Channel steel, also known as channel steel, is a type of steel with a cross-sectional shape that is approximately C-shaped. The fixing portion 1131 is joined to the inner edge of the lower frame 11a with the open side of the C-shape facing upwards. The method of joining the fixing portion 1131 to the inner edge of the lower frame 11a is not limited, but in this embodiment, welding is used.

[0037] The screw-type adjustable leg 1132 comprises a screw shaft with threads on its side and a plate-shaped member located at the tip of the screw shaft, which is the lower tip in the upper diagram of Figure 3. The plate-shaped member increases the contact area of ​​the screw-type adjustable leg 1132 with the floor surface, thereby reducing the contact pressure per unit area and protecting the floor surface.

[0038] The lower end surface of the fixing portion 1131, which is fixed to the lower frame 11a, has a through hole formed through which the screw shaft of the screw-type adjustment leg 1132 passes.

[0039] Nut 1133 is a nut that corresponds to the screw shaft of the screw-type adjustable leg 1132. The size of nut 1133, which has a regular hexagonal shape in plan view (the distance between two pairs of opposite sides among the six sides that make up the regular hexagon), is larger than the inner diameter of the through hole formed in the fixing part 1131. Therefore, as shown in the upper diagram of Figure 3, by fitting nut 1133 onto the screw shaft of the screw-type adjustable leg 1132 and passing it through the through hole from below the fixing part 1131, the leg 113 can adjust the gap between the floor frame 11 (lower frame 11a) and the floor surface.

[0040] In the case of the leg portion 113, the total length is defined as the length from the lower end surface of the plate-shaped member (the surface in contact with the floor) to the upper end surface of the fixing portion 1131. In this embodiment, it is preferable that the total length of each leg portion 113 is less than the thickness of the floor frame 11 (the sum of the thickness of the lower frame 11a and the thickness of the upper frame 11b). However, the total length of each leg portion 113 may be greater than or equal to the thickness of the floor frame 11.

[0041] (Wall frame) The four wall frames 12 that define the sides of the internal section of the space unit 10 are frames that fix the relative position of the ceiling frame 13 with respect to the floor frame 11, while the floor frame 11 and ceiling frame 13 described above are spaced apart from each other. As shown in the plan view of Figure 2, when the unit system 1 is viewed from the positive y-axis direction, the floor frame 11 and ceiling frame 13 are aligned and overlapping.

[0042] Each of the four wall frames 12, like the floor frame 11 and ceiling frame 13, is an annular member obtained (constructed) by bending a square pipe whose cross-sectional shape is a rounded rectangle. Each of the four wall frames 12 constitutes a side wall or side that surrounds the internal section of the space unit 10 from all four sides.

[0043] As shown in Figures 1 and 2, this embodiment employs a wall frame 12 whose plan view shape is a rounded square. The floor frame 11 and the ceiling frame 13 also each have a rounded square shape in plan view. Therefore, the three-dimensional frame of the space unit 10, defined by the floor frame 11, the four wall frames 12, and the ceiling frame 13, has the shape of a rounded cube. In other words, in this embodiment, the shape of the internal space defined by the three-dimensional frame is a rounded cube.

[0044] In one embodiment of the unit system 1, the inner area of ​​the wall frame 12 may be open or closed using wall panels attached to the wall frame 12.

[0045] For example, in the space unit 10 shown in Figure 1, the wall frames 12 that make up the right side (see the upper diagram in Figure 1) and the left side (see the lower diagram in Figure 1) are open in their inner areas.

[0046] On the other hand, in the space unit 10 shown in Figure 1, three wood panels 153 are attached to the inner area of ​​the wall frame 12 that constitutes its front surface. Each wood panel 153 is a metal panel frame 1531, which comprises a panel frame 1531 with a rounded rectangular shape in plan view, and a wooden panel fitted into the inner area of ​​the panel frame 1531.

[0047] The width (length along the x-axis) of each wood panel 153 is 1 / 3 of the width (length along the x-axis) of the wall frame 12 that constitutes the front. In unit system 1, the inner area is closed off by attaching three wood panels 153 to the wall frame 12.

[0048] Furthermore, multiple openings are periodically formed along the direction in which the longer side (the side extending parallel to the y-axis) of the panel frame 1531 extends. A columnar member with multiple openings formed periodically in this way is also called a shelf column.

[0049] Each opening in the gacha column can be secured by inserting an attachment, which has a corresponding insertion part, into the opening. In this embodiment, as shown in the upper part of Figure 1, the shelf arm SA is attached to the panel frame 1531. Note that in the upper part of Figure 1, the shelf boards that constitute the shelf together with the shelf arm SA are not shown.

[0050] The attachments that are mounted to the panel frame of the wall frame 12 are not limited to shelf arms SA, but can be selected as appropriate.

[0051] Furthermore, in the space unit 10 shown in Figure 1, the wall frame 12 that constitutes the back of the unit has two glass panels 151 and one barn door 152 attached to its inner area. Each of the glass panels 151 and barn door 152 is a metal panel frame, comprising a panel frame with a rounded rectangular shape in plan view and a glass panel fitted into the inner area of ​​the panel frame.

[0052] Furthermore, the barn door 152 is configured to be able to be opened and closed by sliding within the inner region of the wall frame 12.

[0053] The barn door 152 includes two pulleys 1521 mounted above the panel frame and a lower guide 1522 mounted below the panel frame as an opening and closing sliding mechanism. Additionally, a guide rail 121 is provided on the upper outer edge of the wall frame 12, allowing the pulleys 1521 to slide. By placing the pulleys 1521 of the barn door 152 on the guide rail 121, the barn door 152 can be suspended within the inner region of the wall frame 12. Furthermore, the lower guide 1522 below the barn door 152 allows the suspended barn door 152 to slide stably.

[0054] The width of each glass panel 151 and barn door 152 is 1 / 3 of the width of the wall frame 12 that constitutes the plane.

[0055] Furthermore, a counter table 154 is attached to the wall frame 12 that constitutes the left side (see the lower diagram in Figure 1). The counter table 154 comprises a horizontal bar 1541, a table arm 1542, and a top plate 1543. The horizontal bar 1541 is a rod-shaped member provided in the internal area of ​​the wall frame 12.

[0056] The horizontal bar 1541 is fixed to the inner edge of the wall frame 12 so as to traverse the internal region parallel to the z-axis direction. The table arm 1542 is a rod-shaped member provided to protrude from the horizontal bar 1541. The top plate 1543 is a plate-shaped member fixed to the tip of the rod-shaped member.

[0057] The glass panel 151, barn door 152, and wood panel 153, configured as described above, are all forms of wall panels that can be detachably attached to the wall frame 12. The configuration of the part of these wall panels that attaches to the wall frame 12 is standardized. Therefore, any wall panel configured to meet the attachment standards of the wall frame 12 can be freely attached to and detached from the wall frame 12. Thus, the configuration of the walls that define the interior space of the space unit 10 can be easily changed.

[0058] The materials that make up the wall panels are not limited to wood (including solid wood, veneer, and plywood with a wood-grain film applied to the surface) and glass. Examples of other materials include tiles (including tile-like materials), bricks (including brick-like materials), and resin. The panels may also be made of mirror.

[0059] In this embodiment, the width of each wall panel is set to 1 / 3 of the width of the wall frame 12. However, the width of the wall panel is not limited to 1 / 3 of the width of the wall frame 12 and can be determined as appropriate. Similarly, the height (length along the y-axis) of each wall panel can also be determined as appropriate. It is preferable that the width and height of the wall panel are standardized based on the size of the wall frame 12. Preferred examples of wall panel widths and heights include sizes obtained by dividing the width and height of the wall frame 12 by a natural number (1, 2, 3, ...).

[0060] (louver) As shown in the upper and lower figures of Figure 1, the inner region surrounded by the inner edge of the ceiling frame 13 is provided with multiple (eight in this embodiment) louvers 131 and one light-mounting louver 131L. Note that in the upper and lower figures of Figure 1, only three of the eight louvers 131 are denoted by the reference numeral 131.

[0061] Both the louvers 131 and the light-mounting louvers 131L are plate-like members that span between pairs of opposing sides of the four sides that make up the ceiling frame 13.

[0062] The louvers 131 and the light-mounted louvers 131L have the function of distinguishing the internal space of the space unit 10 from the external space that extends above the space unit 10. The higher the ratio of the area occupied by the louvers 131 and the light-mounted louvers 131L to the area of ​​the internal region of the ceiling frame 13 (i.e., the lower the opening ratio of the ceiling frame 13), the stronger the sense that the internal space of the space unit 10 is distinguished from the external space. Therefore, the opening ratio of the ceiling frame 13 can be adjusted by appropriately designing the number and width of the louvers 131 and the light-mounted louvers 131L.

[0063] Furthermore, the 131L light mounting louver has a built-in rail for attaching lights (such as pendant lights), also known as a track lighting rail. Therefore, the 131L light mounting louver has built-in wiring for power supply.

[0064] This wiring is routed, for example, from the inner region of the floor frame 11 into the interior of the square pipes that make up the floor frame 11, then through the interior of the square pipes of the wall frame 12 and the interior of the square pipes of the ceiling frame 13, and finally into the interior of the light mounting louvers 131L. In this case, it is sufficient to form an opening in a part of the inner surface (the side surrounding the inner region) of the square pipes that make up the floor frame 11 to allow the wiring to be routed into the interior of the square pipes of the floor frame 11. Alternatively, in the region where the square pipes that make up the floor frame 11 and the square pipes that make up the wall frame 12 are facing each other and in close proximity, a pair of openings can be formed in a part of each square pipe to allow the wiring to be routed from the interior of the square pipes of the floor frame 11 to the interior of the square pipes of the wall frame 12. Similarly, in the region where the square pipes that make up the wall frame 12 and the square pipes that make up the ceiling frame 13 are facing each other and in close proximity, a pair of openings can be formed in a part of each square pipe to allow the wiring to be routed from the interior of the square pipes of the wall frame 12 to the interior of the square pipes of the ceiling frame 13. Furthermore, an opening can be formed in a part of the inner surface (the side surrounding the inner area) of the square pipe that constitutes the ceiling frame 13, corresponding to the position where the light mounting louver 131L is attached, to allow wiring to be passed from the inside of the square pipe of the ceiling frame 13 to the inside of the light mounting louver 131L. By configuring it in this way, power can be supplied to the light without the wiring being exposed to the outside of the three-dimensional frame.

[0065] (Floorboards and spacers) Next, the floorboard 14 and spacer 16 will be described with reference to Figures 1, 3, and 4.

[0066] The floorboard 14 is a plate-like member placed in the inner region surrounded by the inner edge of the floor frame 11 (see the lower diagram in Figure 1, the upper diagram in Figure 3, and the upper diagram in Figure 4). In this embodiment, the floorboard 14 is divided into a plurality of subfloorboards 141 and subfloorboards 142. Specifically, the floorboard 14 is divided into a total of 16 equal parts in a 4x4 grid.

[0067] The floor frame 11 is a closed annular member with a rounded square shape in plan view. Therefore, the plan view shape of the inner region of the floor frame 11 is also a rounded square. Of the 16 subfloor panels, the subfloor panels corresponding to the four corners of the inner region are designated as subfloor panels 141, and the remaining subfloor panels are designated as subfloor panels 142.

[0068] The materials that make up the floorboards 14 (i.e., the subfloorboards 141 and 142) may be wood, tiles, bricks, or cobblestones, just like the materials that make up the wall panels. Furthermore, glass may be used to construct the floorboards 14, provided that sufficient strength can be ensured.

[0069] Note that the floorboard 14 does not necessarily have to be divided into multiple sub-floorboards. However, if ease of transporting and installing the floorboard 14 is a priority, it is preferable that the floorboard 14 be divided into multiple sub-floorboards.

[0070] Multiple spacers 16, which are one embodiment of multiple first legs, are provided in the inner region of the floor frame 11. The multiple spacers 16 support the floorboard 14 by being interposed between the floorboard 14 and the floor surface.

[0071] As shown in the plan view of Figure 2, a total of 25 spacers 16 are arranged in a 5x5 matrix within the inner region of the floor frame 11. Of the 25 spacers 16, four spacers 16, which are positioned corresponding to the four corners of the inner region, support the rounded corner portions of the subfloor panels 141. The remaining 21 spacers 16 support one of the following collectively: (1) the corner portions of subfloor panels 141 and 142, (2) the corner portions of two subfloor panels 142, or (3) the corner portions of four subfloor panels 142. In this way, at least one of the multiple spacers 16 is located at the boundary where two or more subfloor panels 142 meet, and supports the two or more subfloor panels 142.

[0072] Each spacer 16 is equipped with a screw-type adjustment shaft 161 and a screw-type adjustment leg 162 (see upper diagram in Figure 3).

[0073] The screw-type adjustment shaft 161 comprises a screw shaft with screw threads (male threads) on its outer surface, and a flange provided at the tip of the screw shaft, which is the upper tip in the upper diagram of Figure 3. The flange increases the contact area of ​​the screw-type adjustment shaft 161 with respect to the floor plate 14, thereby reducing the contact pressure per unit area and protecting the floor plate 14.

[0074] The screw-type adjustable leg 162 is an annular member having screw threads (female threads) on its inner surface, corresponding to the screw threads of the screw-type adjustable shaft 161. The lower part of the annular screw-type adjustable leg 162 has an enlarged outer diameter in a flange shape. The enlarged outer diameter of the flange-shaped portion increases the contact area of ​​the screw-type adjustable leg 162 with the floor surface, thereby reducing the contact pressure per unit area and consequently protecting the floor surface.

[0075] Each spacer 16 configured in this way can adjust the gap between the floorboard 14 and the floor surface. In other words, each spacer 16 can adjust the position of the floorboard 14 in the inner region of the upper frame 11b (more specifically, its position in the y-axis direction).

[0076] In this embodiment, the lower frame 11a and upper frame 11b that constitute the floor frame 11 are annular members obtained by bending a square pipe having a rounded rectangular cross-section. Here, it is more preferable that the upper frame 11b, which houses the floor plate 14 in its inner region, is an annular member obtained by bending a square pipe.

[0077] As shown in the upper part of Figure 4, since the cross-sectional shape of the square pipe is a rounded rectangle, a curved surface 11R is formed at the corner of the square pipe. In this embodiment, each spacer 16 is adjusted so that the upper surface of the floorboard 14 (the surface located on the positive y-axis side in the upper part of Figure 4) substantially coincides with the lower end of the curved surface 11R that forms the upper surface of the floor frame 11 (the surface located on the positive y-axis side in the upper part of Figure 4).

[0078] In the case of spacer 16, the total length is defined as the length from the lower end surface to the upper end surface (i.e., the length from the lower end surface of the screw-type adjustment leg 162 to the upper end surface of the screw-type adjustment shaft 161). Preferably, the total length of each spacer 16 is less than the thickness of the floor frame 11 (the sum of the thickness of the lower frame 11a and the thickness of the upper frame 11b). However, the total length of each spacer 16 may be greater than or equal to the thickness of the floor frame 11.

[0079] <Deck Unit> (Floor frame, floorboards, and spacers) The deck unit 20 includes a floor frame 21. The floor frame 21 defines a two-dimensional area on the floor surface. The floor frame 21 is an example of a second floor frame.

[0080] Furthermore, the deck unit 20 includes, in addition to the floor frame 21, a floorboard 24 and a plurality of spacers 26.

[0081] In this embodiment, the deck unit 20 is described as constituting the unit system 1 together with the space unit 10. However, the deck unit 20 can also be used on its own.

[0082] As shown in Figures 1 and 2, this embodiment employs a floor frame 21 whose plan view shape is a rounded square. Therefore, the shape of the two-dimensional region defined by the floor frame 21 is square. The floor frame 21, like the floor frame 11, wall frame 12, and ceiling frame 13, is manufactured by forming a hollow metal pipe into a closed, annular, rounded square. In other words, the floor frame 21, wall frame 12, and ceiling frame 13 are each closed annular members.

[0083] However, the plan view shape of the floor frame 21 (the shape obtained when viewed from a direction perpendicular to the upper and lower base surfaces) is not limited to this and can be determined as appropriate. The plan view shape of the floor frame 21 may be, for example, rectangular. Furthermore, the plan view shape of the floor frame 21 is not limited to a quadrilateral shape, but may be a polygon with any number of angles.

[0084] As mentioned above, the space unit 10 and the deck unit 20 are adjacent to each other. Therefore, in order to reduce the gap between the space unit 10 and the deck unit 20 that may occur when they are adjacent, it is preferable that the plan view shape of the floor frame 21 in the deck unit 20 includes a portion (i.e., an edge) that is made up of straight lines.

[0085] The deck unit 20 configured in this way can be described as a configuration in which the four wall frames 12 and the ceiling frame 13 of the space unit 10 have been omitted. In other words, the deck unit 20 can be described as a configuration corresponding to the floor frame 11, floorboard 14, spacer 16, and leg portion 113 of the space unit 10. Therefore, in this embodiment, the deck unit 20 will be briefly described while clarifying the correspondence between the deck unit 20 and each component of the space unit 10.

[0086] Each of the floor frame 21, floorboard 24, and spacer 26 provided in the deck unit 20 corresponds to the floor frame 11, floorboard 14, and spacer 16 provided in the space unit 10, respectively.

[0087] In other words, the deck unit 20 comprises a floor frame 21 which is a closed annular member, a plurality of legs 213 fixed to the inner edge of the floor frame 21, and a floor plate 24 placed in an inner region surrounded by the inner edge of the floor frame 21. The legs 213 correspond to the legs 113 in the floor frame 11 of the space unit 10 and are an example of a first leg.

[0088] Furthermore, the floor frame 21, like the lower frame 11a and upper frame 11b of the floor frame 11, comprises a lower frame 21a and an upper frame 21b. The lower frame 21a is constructed in the same way as the lower frame 11a. On the other hand, the upper frame 21b is designed to be slightly larger than the lower frame 11a. Therefore, the upper frame 21b is designed to be slightly larger than the lower frame 21a. The inner edge of the upper frame 21b is designed to roughly coincide with the outer edge of the lower frame 21a (see Figures 2 and 3). Also, the lower frame 21a and the upper frame 21b are welded to each other.

[0089] Each leg portion 213 is located in the inner region of the floor frame 21 when the floor frame 21 is viewed from above.

[0090] Furthermore, it is preferable that the total length of each leg portion 213 is less than the thickness of the floor frame 21. However, the total length of the leg portion 213 may be greater than or equal to the thickness of the floor frame 21. In this embodiment, the thickness of the floor frame 21 is approximately equal to the sum of the thickness of the lower frame 21a and the thickness of the upper frame 21b.

[0091] Multiple legs 213 can adjust the gap between the floor frame 21 and the floor surface. The configuration of each leg 213 (see the lower diagram in Figure 3) is the same as the configuration of each leg 113 of the space unit 10 (see the upper diagram in Figure 3). That is, each of the fixing part 2131, screw-type adjustment leg 2132, and nut 2133 provided on the leg 213 has the same configuration as the fixing part 1131, screw-type adjustment leg 1132, and nut 1133 provided on the leg 113.

[0092] Multiple spacers 26, which are one embodiment of multiple second legs, are provided in the inner region of the floor frame 21. The multiple spacers 26 support the floorboard 24. The configuration of each spacer 26 (see lower diagram in Figure 3) is the same as the configuration of each spacer 16 of the space unit 10 (see upper diagram in Figure 3). That is, each of the screw-type adjustment shafts 261 and screw-type adjustment legs 262 provided by the spacer 26 (see lower diagram in Figure 3) has the same configuration as the screw-type adjustment shafts 161 and screw-type adjustment legs 162 provided by the spacer 16 (see upper diagram in Figure 3). Each spacer 26 can adjust the gap between the floorboard 24 and the floor surface. Preferably, the total length of the spacer 26 is less than the thickness of the floor frame 21. However, the total length of the spacer 26 may be greater than or equal to the thickness of the floor frame 21.

[0093] The floor frame 21, like the floor frame 11, is an annular member obtained (constructed) by bending a square pipe whose cross-sectional shape is a rounded rectangle.

[0094] Each spacer 26 is adjusted so that the upper surface of the floorboard 24 (sub-floorboard 241) substantially coincides with the lower end of the curved surface 21R that forms the upper surface of the floor frame 21 (see the arrow in Figure 4).

[0095] The floorboard 24, like the floorboard 14, consists of multiple subfloorboards 241 and 242 (see the upper diagram in Figure 1).

[0096] (Deck Unit System) Furthermore, the deck unit 20 is equipped with fixtures 30. Thus, a deck unit system comprising the deck unit 20 and fixtures 30 is also included in the scope of the present invention. Hereinafter, a deck unit system which is one aspect of the present invention will be described with reference to the upper view of Figure 1 and the plan view of Figure 2.

[0097] As shown in the plan view of Figure 2, the interior region of the floor frame 21 is provided with rails 211 that connect pairs of opposite sides of the four sides of the floor frame 21. The rails 211 are provided with fastening parts 212 for fastening columnar members (legs 31 of the furniture 30, which will be described later). In this embodiment, the fastening part 212 is a cylindrical member whose inner diameter is slightly larger than the outer diameter of the leg 31. In this embodiment, the fastening part 212 is welded to the rail 211. However, the method of joining the fastening part 212 to the rail 211 is not limited to welding.

[0098] Furthermore, the floor plate 24 has through holes 243 formed at positions corresponding to the fastening portions 212 (see the upper diagram in Figure 1).

[0099] As shown in the upper part of Figure 1, the furniture 30 comprises legs 31 and a tabletop 32. The legs 31 are cylindrical, and the tabletop 32 is a plate-like member fixed to the upper end of the legs 31. In other words, the furniture 30 is a single-legged table.

[0100] As described above, the inner diameter of the fastening portion 212 is slightly larger than the outer diameter of the leg 31. Therefore, in this deck unit system, the leg 31 can be fastened to the fastening portion 212 by inserting the lower end of the leg 31 into the fastening portion 212.

[0101] In this embodiment, the case in which the furniture 30 is installed on the deck unit 20 is used as an example, but the furniture 30 can also be installed on the space unit 10. In that case, a rail and fasteners configured in the same way as the rail 211 and fasteners 212 can be provided in the internal area of ​​the floor frame 11 of the space unit 10. With this configuration, the lower end of the leg 31 can be inserted into the fastener provided in the internal area of ​​the floor frame 11, so that the leg 31 can be fastened to the fastener.

[0102] (Unit system configuration) In this embodiment, each of the floor frame 11 and floor frame 21 of the unit system 1 is equipped with a leg portion 113 and a leg portion 213, respectively, which are examples of height adjustment mechanisms. However, in one embodiment of the unit system 1, it is sufficient if at least one of the floor frame 11 and floor frame 21 is equipped with a height adjustment mechanism.

[0103] In this embodiment, the plan view shape of each of the floor frames 11 and 21 is a rounded square, as described above. As shown in the upper part of Figure 1, the first side, which is one of the four sides constituting the floor frame 11 (one of the two sides parallel to the z-axis that is located on the positive x-axis side), and the second side, which is one of the four sides constituting the floor frame 21 (one of the two sides parallel to the z-axis that is located on the negative x-axis side), are adjacent to each other.

[0104] As described above, since at least one of the floor frame 11 and the floor frame 21 is equipped with a height adjustment mechanism, the heights of the first side and the second side can be made equal in the area where the floor frame 11 and the floor frame 21 are adjacent.

[0105] Furthermore, in one embodiment of the unit system 1, the floor frame 11 and the floor frame 21 may both have a rectangular shape in plan view, with either side of the floor frame 11 designated as the first side and either side of the floor frame 21 designated as the second side, and a configuration in which m times the length of the first side (where m is a natural number) and n times the length of the second side (where n is a natural number) are equal.

[0106] Furthermore, one embodiment of the unit system 1 may include a plurality of space units (e.g., space unit 10). In this case, the plurality of space units and at least one deck unit may be arranged such that any of the plurality of space units and any of the at least one deck unit (e.g., deck unit 20) are adjacent to each other. Alternatively, the plurality of space units and the at least one deck unit may be arranged such that at least one deck unit (e.g., deck unit 20) is interposed between two of the plurality of space units.

[0107] Variations in the layout of the space unit 10 and deck unit 20 in one embodiment of these unit systems 1 will be described later with reference to Figures 5 to 7.

[0108] (Example layout in a unit system) An example of the layout of the space unit 10 and deck unit 20 in the unit system 1 will be explained with reference to Figures 5 and 6.

[0109] Figure 5 is a schematic plan view of layouts 1 to 6 using one embodiment of Unit System 1. Figure 6 is a schematic plan view of layout 7 in one embodiment of Unit System 1. Figure 7 is a perspective view of an office laid out using one embodiment of Unit System 1.

[0110] Layout 1 shown in Figure 5 is a layout in which the deck unit 20 is omitted from the unit system 1 shown in Figure 1. In Layout 1, the space unit 10 is denoted as space unit 10A. Thus, it is also possible to use the space unit 10 alone without constructing the deck unit 20 from the unit system 1. Alternatively, as shown in Layout 2 in Figure 5, it is also possible to use two space units 10 (denoted here as space units 10A and 10B). One embodiment of Layout 2 may use three or more space units 10. Furthermore, it is also possible to use the deck unit 20 alone without constructing the space unit 10 from the unit system 1. In this case, the number of deck units 20 used in the layout may be one or multiple. That is, space unit 10A in Layout 1 may be replaced with deck unit 20, or space units 10A and 10B in Layout 2 may be replaced with deck unit 20.

[0111] Layout 3 shown in Figure 5 uses one space unit 10A and two deck units 20 (referred to here as deck units 20A and 20B). Here, if the length of one side of the rounded square space unit 10A is the unit length Lu, then the length of the shorter side of deck unit 20A is equal to the unit length Lu, the length of the longer side of deck unit 20A is 1Lu / 2, the length of the shorter side of deck unit 20B is 1Lu / 2, and the length of the longer side of deck unit 20B is 3Lu / 2.

[0112] Layout 4 shown in Figure 5 uses three space units 10 (referred to here as space units 10A, 10B, and 10C) and one deck unit 20 (referred to here as deck unit 20C). Space units 10B and 10C are all the same size as space unit 10A. Similarly, deck unit 20C is also the same size as space unit 10A. That is, the length of each side of deck unit 20C is equal to the unit length Lu.

[0113] Layout 5, shown in Figure 5, uses two space units 10 (referred to here as space units 10A and 10C) and two deck units 20 (referred to here as deck units 20C and 20D). Layout 5 can also be described as a layout based on Layout 4, with space unit 10B replaced by deck unit 20D. Deck unit 20D is the same size as space unit 10A, just like deck unit 20C. That is, the length of each side of deck units 20C and 20D is equal to the unit length Lu.

[0114] The layout 6 shown in Figure 5 uses four space units 10 (referred to here as space units 10A, 10B, 10C, and 10D) and five deck units 20 (referred to here as deck units 20A, 20D, 20E, 20F, and 20G). Space units 10B, 10C, and 10D are all the same size as space unit 10A. Deck units 20D, 20F, and 20G are all the same size as deck unit 20A. That is, the length of the short side of deck unit 20A is equal to the unit length Lu, and the length of the long side of deck unit 20A is 1 Lu / 2. Also, each side of deck unit 20E is 1 Lu / 2.

[0115] As described above, the unit system 1 allows for flexible layout of any number of space units 10 and any number of deck units 20, depending on the conditions of the installation location (such as area and shape), after appropriately setting the sizes of the space units 10 and deck units 20.

[0116] Furthermore, layout 7 shown in Figure 6 uses three space units 10A, three deck units 20E, and four deck units 20H. Space units 10A and deck units 20E are the same as those shown in Figure 5, so their explanation is omitted here. The deck units 20H have a long side length of 3Lu / 4 and a short side length of Lu / 2. Layout 7 will also be referenced in the explanation of the deck unit set described later.

[0117] Figure 7 shows an office layout using one embodiment of Unit System 1. In Figure 7, the space unit 10 and deck unit 20 are clearly indicated by either reference numeral 10 or reference numeral 20. Some of the space unit 10 and deck unit 20 are furnished with furniture and fitness equipment corresponding to the fixtures 30. However, reference numeral 30 is not shown in Figure 7.

[0118] The office shown in Figure 7 is broadly divided into three zones: a workplace zone, a shared relaxation zone, and a wellness zone.

[0119] Within the workplace zone, the space unit 10 is designed to be suitably used as, for example, a conference room, a private office, a workstation room, and an online conference room.

[0120] In the shared relaxation zone, the space unit 10 is designed to be suitable for use as, for example, a cafe, bar, DJ booth, simple broadcasting station, and greenhouse containing ornamental plants. The deck unit 20 may also be furnished with, for example, tables, chairs, and plants.

[0121] In the wellness zone, the space unit 10 is designed to be suitable for use as, for example, a chat room, a meditation room, and a training room.

[0122] <Deck Unit Set> Furthermore, a deck unit set comprising a first type of deck unit 20 and a second type of deck unit 20, as described above, is also included in the scope of the present invention. Each of the first type of deck unit 20 and the second type of deck unit 20 is an example of the first deck unit and the second deck unit, respectively.

[0123] Here, the types of deck units 20 may be classified by the size of the floor frame 21 when viewed from above, by the presence or absence of the 30 attached to the deck unit 20, or by the type of the 30 attached to the deck unit 20. Furthermore, the number of first-type deck units 20 constituting the deck unit set may be one or more, and the number of second-type deck units 20 constituting the deck unit set may be one or more.

[0124] The plan view shape of each first type of deck unit 20 and each second type of deck unit 20 can be a rectangle.

[0125] It is preferable that, with any one side of each first type of deck unit 20 designated as the first side and any one side of each second type of deck unit 20 designated as the second side, m times the length of the first side (where m is a natural number) and n times the length of the second side (where n is a natural number) are equal.

[0126] A concrete example of such a deck unit set is layout 7 shown in Figure 6.

[0127] Layout 7 uses three deck units 20E and four deck units 20H as deck units 20. Each deck unit 20E and each deck unit 20H have different sizes when viewed from above. Therefore, each deck unit 20E and each deck unit 20H are examples of the first type of deck unit 20 and the second type of deck unit 20, respectively.

[0128] The length of the longer side of deck unit 20H is 3 / 2 times the length of each side of deck unit 20E. That is, m=3 and n=2. Also, the length of the shorter side of deck unit 20H is 1 times the length of each side of deck unit 20E. That is, m,n=1.

[0129] 〔summary〕 In the deck unit described in Patent Document 1 (Japanese Patent Publication No. 2023-001645) mentioned above, the portion corresponding to the contour of the floor surface (referred to as the outer edge) is more susceptible to various forces than the inner region of the floor surface (the region surrounded by the outer edge). Therefore, the outer edge of this deck unit is more prone to damage compared to the inner region.

[0130] For example, in the deck unit described in Patent Document 1, the plan view shape may be square as shown in Figure 1, or it may be rectangular as shown in Figure 8. By combining deck units having these various plan view shapes, a wide variety of deck unit layouts can be formed. When such layout changes are implemented, the outer edges of adjacent deck units are prone to collision and, consequently, damage.

[0131] Furthermore, even when using the installed deck units without changing the layout, the load on various parts of the floor surface due to the user's use of the deck units tends to be higher at the outer edges and relatively lower in the inner areas of the floor surface.

[0132] When a load (e.g., the user's weight) is applied to the inner area of ​​the floor surface, the floor surface bears the load over a planar area with a certain surface area (e.g., the area corresponding to the sole of the user's shoes). On the other hand, when a load is applied to the outer edge of the floor surface, the floor surface bears the load over a linear area with a relatively small surface area (e.g., the corner of the floor surface). Therefore, even when using the installed deck unit as is, the outer edge of the deck unit is susceptible to damage.

[0133] One aspect of the present invention has been made in view of these problems, and its purpose is to reduce the possibility of damage occurring to the outer edge of a floorboard in a deck unit comprising a floor frame, a plurality of legs, and a floorboard.

[0134] To achieve the above objective, a deck unit according to a first aspect of the present invention comprises a floor frame which is a closed annular member, a plurality of first legs fixed to the floor frame, and a floor plate placed in an inner region surrounded by the inner edge of the floor frame.

[0135] According to the above configuration, the floorboards are surrounded by the floor frame. In other words, the outer edges of the floorboards are protected by the floor frame. Therefore, this deck unit can reduce the possibility of damage to the outer edges of the floorboards compared to the deck unit described in Patent Document 1.

[0136] Furthermore, in the deck unit described in Patent Document 1, the cross-section of the floor surface is often exposed on a part of its outer edge. The cross-section of the floor surface is prone to having sharp corners, and depending on the material that makes up the floor surface, it is likely to have splinters or burrs. Therefore, in the deck unit described in Patent Document 1, there is a risk that the user may suffer injury for unforeseen reasons.

[0137] Because the outer edges of the floorboards of this deck unit are protected by a floor frame, it has the secondary effect of reducing the risk of injury to the user compared to the deck unit described in Patent Document 1.

[0138] Furthermore, in the deck unit according to the second aspect of the present invention, in addition to the configuration of the deck unit according to the first aspect described above, each of the plurality of first legs has an overall length less than the thickness of the floor frame and is provided in the inner region when the floor frame is viewed in plan.

[0139] In the deck unit described in Patent Document 1, the multiple legs support the underfloor frame and are configured to bring the underfloor frame closer to a horizontal state and reduce rattling in the underfloor frame. Each leg is equipped with a screw that allows the length of the leg to be adjusted by rotation. By adjusting the length of each leg using the screw, the underfloor frame can be brought closer to a horizontal state regardless of the slope or unevenness of the floor surface.

[0140] However, in the deck unit described in Patent Document 1, multiple legs are provided below the underfloor frame, so when a person outside the deck unit looks at it, multiple legs are exposed and conspicuous (see Figure 1 of Patent Document 1).

[0141] Furthermore, in the deck unit described in Patent Document 1, since multiple legs are provided below the underfloor frame, a large gap is created between the underfloor frame and the floor surface depending on the height of each leg.

[0142] Thus, a configuration in which multiple legs are conspicuously exposed, and where a large gap is created between the underfloor frame and the floor surface, is undesirable as it may detract from the aesthetics of the deck unit. In other words, such a configuration reduces the design freedom of the deck unit designer.

[0143] According to the above configuration, the total length of the multiple first legs is less than the thickness of the floor frame, and the multiple first legs are located in the inner region of the floor frame. Therefore, with this deck unit, even when viewed from outside the deck unit, the multiple first legs are hidden by the floor frame and are not easily exposed. Furthermore, with this deck unit, compared to the deck unit described in Patent Document 1, the gap that may occur between the floor frame and the floor surface can be reduced (or even eliminated in some cases). Thus, this deck unit, which comprises a floor frame, multiple legs, and a floorboard, can increase the freedom of the designer.

[0144] Furthermore, in the deck unit according to the third aspect of the present invention, in addition to the configuration of the deck unit according to the second aspect described above, the plurality of first legs are configured to adjust the gap between the floor frame and the floor surface.

[0145] According to the above configuration, when the floor frame is placed on the floor surface, it is possible to make the floor frame closer to a horizontal position and reduce rattling in the floor frame.

[0146] Furthermore, in the deck unit according to the fourth aspect of the present invention, in addition to the configuration of the deck unit according to the third aspect described above, it further comprises a plurality of second legs provided in the inner region, which support the floorboard. In this deck unit, each of the plurality of second legs has an overall length less than the thickness of the floor frame and is configured to allow adjustment of the gap between the floorboard and the floor surface.

[0147] With the above configuration, when the floorboard is placed in the inner area, it is possible to make the floorboard closer to horizontal and reduce rattling of the floorboard. Furthermore, in this deck unit, since the floorboard is simply placed on the second leg, it is easy to replace it with a different type of floorboard with a different pattern or material. The thickness of the floorboard may vary depending on the type of floorboard. Therefore, it is conceivable that as a result of replacing the floorboard, the position of the top surface of the floorboard relative to the top surface of the floor frame may be in an unintended position. Even in such cases, the position of the top surface of the floorboard relative to the top surface of the floor frame can be adjusted to the intended position by using the second leg.

[0148] Furthermore, in the deck unit according to the fifth aspect of the present invention, in addition to the configuration of the deck unit according to the fourth aspect described above, the floor frame is an annular member obtained by bending a square pipe having a rounded rectangular cross-section, and each of the plurality of second legs is adjusted so that the upper surface of the floor plate substantially coincides with the lower end of the curved surface forming the upper surface of the floor frame.

[0149] With the above configuration, the top surface of the floor frame and the top surface of the floorboard are smoothly continuous, improving the aesthetics of the deck unit and reducing the possibility of people tripping. In addition, since the cross-section of the floorboard is not exposed from the top surface of the floor frame, the aesthetics of the deck unit are further improved.

[0150] Furthermore, in the deck unit according to the sixth aspect of the present invention, in addition to the configuration of the deck unit according to the fifth aspect described above, the floorboard is configured to consist of a plurality of sub-floorboards.

[0151] With the above configuration, the large floorboard is divided into several smaller sub-floorboards, making it easier to install and move the deck unit.

[0152] Furthermore, in the deck unit according to the seventh aspect of the present invention, in addition to the configuration of the deck unit according to the sixth aspect described above, at least one of the plurality of second legs is located at the boundary where two or more of the plurality of subfloor boards meet, and supports the two or more subfloor boards.

[0153] With the above configuration, the secondary floorboard can be made more stable compared to the case where the second leg supports the area near the center of the secondary floorboard.

[0154] Furthermore, in the deck unit according to the eighth aspect of the present invention, in addition to the configuration of the deck unit according to any one of the first to seventh aspects described above, at least one rib is provided in the inner region of the floor frame, which is provided with fastening parts for fastening columnar members, and through holes are formed in the floorboard at positions corresponding to the fastening parts.

[0155] With the above configuration, when installing furniture on this deck unit, the legs of the furniture, which are columnar members, can be secured by fastening them to the slats of the floor frame. Therefore, compared to simply placing the furniture on the floorboards, the furniture can be secured more securely and neatly.

[0156] Furthermore, the deck unit system according to the ninth aspect of the present invention comprises the deck unit according to the eighth aspect described above, and a fixture having legs made of columnar members. In this deck unit system, the legs of the fixture are configured to pass through the through holes and be fastened to the fastening portions of the crossbars. With the above configuration, the fixtures can be secured more securely and neatly compared to placing them on a floorboard.
