The present invention relates to a building equipped with a split-level floor.

Buildings with split-level floors are known. For example, Patent Document 1 discloses a house with a stage living room, which is an example of a split-level floor. In this house, the stage living room is set up to face the living room. A staircase is provided in the stage living room. A desk and a chair for using the desk are installed in the passage space. A bookshelf is placed on the desk.

JP 2009-46925 A

In the above-mentioned house, for example, if a user slips while descending the stairs, there is a risk that the user may come into contact with the bookshelf and the bookshelf may fall over. For this reason, there is still room for improvement in terms of optimal use of the split-level floor.

(1) A building related to the present invention comprises a room, a skip floor provided in the room, a main staircase provided in the skip floor connecting the skip floor to a floor higher than the floor on which the room is provided, and storage furniture fixed to the floor of the room and/or the skip floor so as to prevent users of the main staircase from moving from the main staircase to the floor of the room.
In the above-mentioned building, even if a user descending the main staircase slips and comes into contact with a piece of storage furniture, the position of the storage furniture is unlikely to shift or topple over in relation to the floor of the room and the skip-floor. Therefore, the skip-floor can be used advantageously.

(2) In a preferred example, in the building described in (1), the main staircase includes a landing, a first section connecting the floor of the skip-floor and the landing, and a second section connecting the landing and a floor higher than the floor on which the room is provided, and the storage furniture faces the landing and has a top surface located at a higher position than the floor of the landing.
In the above-mentioned building, the storage furniture prevents users of the main staircase from falling from the landing onto the floor of the room, making it possible to make optimal use of the split-level floor.

(3) In a preferred example, in the building described in (2), the height of the tabletop relative to the floor of the landing is in the range of 1,100 mm or more from the floor of the landing.
In the above-mentioned building, since the height of the top board relative to the landing floor falls within the above-mentioned range, the storage furniture more reliably prevents users of the main staircase from falling from the landing onto the floor of the room.

(4) In a preferred example, in the building described in (2) or (3), the height of the top plate relative to the floor of the landing is within a range of 700 mm or less from the ceiling.
In the above-mentioned building, the height of the top board relative to the landing floor falls within the above-mentioned range, so users of the split-level floor are less likely to feel oppressed.

(5) In a preferred example, in the building described in any one of (1) to (4), an auxiliary staircase is further provided connecting the floor of the skip floor and the floor of the room, and the storage furniture is arranged adjacent to the auxiliary staircase.
According to the above-mentioned building, when moving from one side of the split floor and the room floor to the other side via the auxiliary staircase, the storage furniture can be used as a handrail, which improves convenience.

The buildings related to this invention can make good use of split-level floors.

(Embodiment)
An example of a building 10 will be described with reference to Fig. 1. An example of the building 10 is an individual house or an apartment building. In the example shown in Fig. 1, the building 10 is an individual house including multiple floors. Fig. 1 is a plan view showing an indoor structure 20 on the first floor of the individual house. An area 10A surrounded by an exterior wall 11 of the building 10 is partitioned by multiple interior walls 12. In the area 10A partitioned by the multiple interior walls 12, an entrance 30, a room 40, an outdoor space 50, and a skip floor 60, which are the main elements constituting the indoor structure 20, are provided.

The number and arrangement of the entrance 30, rooms 40, and outdoor spaces 50 can be selected as desired. In one example, the rooms 40 include an office 41, a kitchen 42, a dining room 43, and a living room 44. There are no interior walls 12 between the kitchen 42, dining room 43, and living room 44. This allows users of the kitchen 42, dining room 43, and living room 44 to easily communicate with each other. An example of an outdoor space 50 is a wooden deck.

The skip floor 60 is provided in the approximate center of the interior structure 20. This allows easy communication between the user of the skip floor 60 and the users of the kitchen 42, dining room 43, and living room 44. The skip floor 60 is preferably provided in the room 40 so as to be independent of the exterior wall 11 and interior wall 12 that constitute the room 40. The fact that the skip floor 60 is independent of the exterior wall 11 and interior wall 12 that constitute the room 40 means that the skip floor 60 is not structurally connected to the exterior wall 11 and interior wall 12. This makes it difficult for users of the skip floor 60 to feel oppressed. The exterior wall 11 is a wall that is connected to the floor 40A and the ceiling (not shown) of the room 40. The interior wall 12 includes a first type interior wall and a second type interior wall. The first type interior wall is a wall that is connected to the floor 40A and the ceiling of the room 40. The second type interior wall is a wall that is connected to the floor 40A of the room 40 and is not connected to the ceiling.

The height LA (see FIG. 4) of the floor 60A of the split-floor 60 relative to the floor 40A of the room 40 can be selected as desired. In a preferred example, the height LA is set so as to provide a sense of openness to users of the split-floor 60. A preferred example of the height LA is 450 to 592.5 mm (450 mm or more and 592.5 mm or less).

The shortest distance LB between the skip floor 60 and the exterior wall 11 and interior wall 12 that constitute the room 40 can be selected arbitrarily. In a preferred example, the shortest distance LB is set so as to provide a high sense of openness to users of the skip floor 60. In this embodiment, as shown in FIG. 1, the shortest distance LB is the shortest distance between the skip floor 60 and the interior wall 12 that constitutes the office 41. An example of the minimum value of the shortest distance LB is 780 mm. A preferred example of the shortest distance LB is 855 mm or more.

As shown in FIG. 2, the building 10 further includes a staircase 70 and storage furniture 80. The staircase 70 includes a main staircase 71 and an auxiliary staircase 72. The main staircase 71 is provided on the skip floor 60 and connects the skip floor 60 to a floor (hereinafter referred to as the "upper floor") above the floor on which the room 40 is provided. The configuration of the main staircase 71 can be selected arbitrarily. In the first example shown in FIG. 3, etc., the main staircase 71 includes a landing 71A, a first portion 71B connecting the floor 60A of the skip floor 60 to the landing 71A, and a second portion 71C connecting the landing 71A to the upper floor. A handrail 73 (see FIG. 3) is provided on one side of the second portion 71C. The relationship between the number of steps of the first portion 71B and the number of steps of the second portion 71C can be selected arbitrarily. In the example shown in FIG. 3, etc., the number of steps of the second portion 71C is greater than the number of steps of the first portion 71B. Note that a portion of the second portion 71C is omitted in Figures 1 and 2. In the second example, the main staircase 71 directly connects the floor 60A of the split-level floor 60 to the upper floor. In other words, in the second example, the landing 71A and the first portion 71B are omitted from the configuration shown in the first example.

The auxiliary staircase 72 connects the floor 60A of the split floor 60 and the floor 40A of the room 40. The auxiliary staircase 72 includes a first staircase 72A and a second staircase 72B. It is possible to move from one of the split floor 60 and the room 40 to the other via the first staircase 72A and the second staircase 72B. This allows the split floor 60 to be used from a variety of positions. The number of steps of the first staircase 72A and the second staircase 72B can be selected arbitrarily according to the height LA (see FIG. 3). In the example shown in FIG. 2 etc., the number of steps of the first staircase 72A and the second staircase 72B is two. The number of steps of the first staircase 72A and the second staircase 72B may be different.

The positional relationship between the first staircase 72A and the second staircase 72B can be selected as desired. In a preferred example, as shown in FIG. 2, the first staircase 72A and the second staircase 72B are provided facing each other via the skip floor 60. This allows movement from one side of the skip floor 60 and the room 40 to the other side from a wider range.

The storage furniture 80 is provided adjacent to the split floor 60. The storage furniture 80 includes a first storage furniture piece 81, a second storage furniture piece 82, a third storage furniture piece 83, a fourth storage furniture piece 84, and a fifth storage furniture piece 85.

The first storage furniture 81 is provided adjacent to one side of the first staircase 72A. When moving from one of the skip floor 60 and the room 40 to the other, the first storage furniture 81 can be used as a handrail, improving convenience. The first storage furniture 81 faces the landing 71A of the main staircase 71. The first storage furniture 81 is fixed to at least one of the floor 40A of the room 40 and the skip floor 60. In this embodiment, the first storage furniture 81 is fixed to the floor 40A of the room 40. In another example, the first storage furniture 81 is fixed to the skip floor 60, or to the floor 40A of the room 40 and the skip floor 60.

5, the first storage furniture 81 includes a pair of side panels 81A, a top panel 81B, a back panel 81C, multiple partition panels 81D, and an opening 81E. The pair of side panels 81A and the back panel 81C are joined to the floor 40A of the room 40. The pair of side panels 81A, the top panel 81B, and the back panel 81C are joined to each other so as to form a storage space 81X for storing items 100. The multiple partition panels 81D divide the storage space 81X according to the size of the items 100 to be stored in the storage space 81X. The opening 81E faces the kitchen 42 (see FIG. 1). The items 100 to be stored in the storage space 81X can be selected arbitrarily. The items 100 are, for example, electrical appliances and daily necessities. In the example shown in FIG. 5, the items 100 are a refrigerator 100A, a floor-standing air conditioner 100B, a toaster oven 100C, and a cup 100D. Preferably, a louver 100E is provided in the area where the floor-standing air conditioner 100B is placed.

The height LC (see FIG. 4) from the top plate 81B of the first storage furniture 81 to the floor of the landing 71A can be selected arbitrarily. In a preferred example, the height LC is set so that the top plate 81B is higher than the landing 71A so that even if a user descending the second portion 71C of the main staircase 71 slips, the user is prevented from falling onto the floor 40A of the room 40. In a more preferred example, an example of the minimum value of the height LC is 1100 mm. When the height LC is within the range of 1100 mm or more, the first storage furniture 81 more reliably prevents a user of the main staircase 71 from falling from the landing 71A onto the floor 40A of the room 40.

The height LD (see FIG. 4) of the top plate 81B of the first storage furniture 81 relative to the floor 60A of the skip floor 60 can be selected as desired. A preferred example of the height LD is 1550 to 1692.5 mm (1550 mm or more and 1692.5 mm or less). When the height LD is 1550 to 1692.5 mm, the height LC of the landing 71A relative to the floor can be secured by securing the distance between the floor 60A of the skip floor 60 and the top plate 81B of the first storage furniture 81, so that the first storage furniture 81 more reliably prevents users of the main staircase 71 from falling from the landing 71A to the floor 40A of the room 40.

The height LE (see FIG. 4) of the top plate 81B of the first storage furniture 81 relative to the floor 40A of the room 40 can be selected arbitrarily. In a preferred example, the top plate 81B of the first storage furniture 81 is preferably located at a height position 415 to 700 mm (415 mm or more and 700 mm or less) away from the ceiling of the floor on which the first storage furniture is installed. A preferred example of the height LE of the first storage furniture 81 is 2000 to 2285 mm (2000 mm or more and 2285 mm or less). When the height LE is 2000 to 2285 mm, the height of the skip floor 60 and the height of the landing 71A can be ensured, and the height LC of the top plate 81B of the first storage furniture 81 relative to the floor of the landing 71A can be ensured, so that the first storage furniture 81 more reliably prevents users of the main staircase 71 from falling from the landing 71A to the floor 40A of the room 40.

As shown in FIG. 2, the second storage furniture 82 is provided adjacent to one side of the second staircase 72B. The second storage furniture 82 can be used as a handrail when moving from one side of the skip floor 60 and the room 40 to the other, improving convenience.

The pair of side panels 82A, the top panel 82B, the back panel 82C, the louver panel 82D, and the louver 82E are joined to each other so as to form a storage space 82X that stores an item 200. The item 200 is, for example, a floor-mounted air conditioner.

The third storage furniture 83 shown in FIG. 2 is provided adjacent to at least one of the other side of the first staircase 72A and the other side of the second staircase 72B. In the example shown in FIG. 2, the third storage furniture 83 is provided adjacent to the other side of the first staircase 72A and the other side of the second staircase 72B. When moving from one side of the skip floor 60 and the room 40 to the other, the third storage furniture 83 can be used as a handrail, improving convenience.

As shown in FIG. 7, the third storage furniture 83 includes a pair of side louver panels 83A (see FIG. 6), a top plate 83B, a back plate 83C (see FIG. 6), a front louver panel 83D, a louver 83E, and a plurality of partition plates 83F. The back plate 83C is joined to the floor 40A of the room 40. The pair of side louver panels 83A, the top plate 83B, the back plate 83C, the front louver panel 83D, and the louver 83E are joined to each other so as to form a storage space 83X that stores items 300. The plurality of partition plates 83F divide the storage space 83X according to the size of the items 300 to be stored in the storage space 83X. The opening 83G faces the living room 44 (see FIG. 1) and the dining room 43 (see FIG. 1). The items 300 to be stored in the storage space 83X can be selected arbitrarily. In the example shown in FIG. 7, the items 300 are a thin television set 300A and a floor-standing air conditioner 300B.
