Summary of the Invention

Problems to be Solved by the Invention

[0005] However, with any of the methods of Patent Documents 1 and 2, it is not possible to easily change the height of the floor according to the purpose of use. Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide a building in which the floor surface can be easily changed according to the use of the floor.

Means for Solving the Problems

[0006] The above problems are solved by the building of the present invention, which includes a floor-side recess provided in the floor, a ceiling-side recess provided in the ceiling and located above the floor-side recess, a movable floor consisting of multiple layers stacked vertically, and a drive mechanism that allows each of the multiple layers constituting the movable floor to move up and down, with at least one of the multiple layers being placed in the ceiling-side recess and the remaining layers being placed in the floor-side recess.

[0007] In the building of the present invention configured as described above, the position of the floor surface can be easily changed by selecting the number of layers to be used as flooring from among the multiple layers that make up the movable floor and placing them in the recess on the floor side, and placing the remaining layers in the recess on the ceiling side, depending on the intended use of the floor.

[0008] Furthermore, in the above-mentioned building, it is preferable that a support member is provided that holds each of the multiple layers and is movable in the vertical direction, and that the support member can be positioned together with the movable floor in the recess on the floor side and the recess on the ceiling side. With the above configuration, each layer of the movable floor can be moved vertically while being properly held in place by the support members.

[0009] Furthermore, in the above-mentioned building, it is preferable that the area enclosed by the outer edge of the receiving member is smaller in size than the openings of the floor-side recess and the ceiling-side recess when the receiving member is viewed from above. With the above configuration, the movable floor can be easily housed inside the recesses on the floor side and the ceiling side.

[0010] Furthermore, in the above-mentioned building, it is preferable that the receiving member deforms by contacting the inner wall surfaces of the floor-side recess and the ceiling-side recess, and while positioned in the floor-side recess, it closes the gap between the movable floor and the inner wall surface of the floor-side recess, and while positioned in the ceiling-side recess, it closes the gap between the movable floor and the inner wall surface of the ceiling-side recess. With the above configuration, the movable floor can be smoothly housed inside the recesses on the floor and ceiling sides. Furthermore, with a relatively simple configuration, it is possible to seal the gap between the movable floor and the inner wall surface of the recess, preventing it from falling into that gap.

[0011] Furthermore, in the above-mentioned building, it is preferable that an edge member is provided which constitutes a part of the peripheral edge surrounding the floor-side recess and is detachably attached to the floor, and when one or more layers are arranged in the floor-side recess, the edge member is removed from the floor and positioned so that the lower end of the edge member fits between the end face of the uppermost layer in the floor-side recess and the inner wall surface of the floor-side recess. With the above configuration, it is possible to seal the gap between the end face of the movable floor and the inner wall surface of the recess on the floor side with a relatively simple structure, thereby preventing objects from falling into the gap.

[0012] Furthermore, in the above-mentioned building, it is preferable that multiple layers are each composed of different materials. According to the above configuration, it becomes possible to select the materials that make up the floor surface (i.e., the material of the topmost layer) according to the intended use of the floor. [Effects of the Invention]

Mode for Carrying Out the Invention

[0015] <<Regarding a building according to one embodiment of the present invention>> Hereinafter, one embodiment of the present invention (hereinafter, this embodiment) will be described with reference to the accompanying drawings. In the drawings, for the sake of easy understanding of the explanation, the structure of each member is shown in a simplified and schematic manner. Also, the sizes (dimensions) of each member shown in the drawings and the intervals between members, etc. are also different from the actual ones.

[0016] Also, in this specification, "horizontal", "vertical", "orthogonal", and "parallel" include the range of errors generally allowed in the technical field of the present invention, and also include a state where there is a deviation within a range of less than several degrees (for example, 2 to 3°) with respect to strict horizontal, vertical, orthogonal, and parallel. In the following description, the up-down direction is the vertical direction.

[0017] Also, in this specification, a plan view means looking at the target member from above, strictly speaking, directly from above.

[0018] Also, in the following description, a house will be cited as an example of a building. Also, in this embodiment, a case where a movable floor is moved within one room (living room) of a house will be described as an example. However, the building of the present invention may be any building that has living rooms, and may be a building other than a residence, such as a shop or facility. Furthermore, it is not limited to one room in a residence, but may involve moving the movable floor across multiple rooms.

[0019] <<Example of building configuration according to one embodiment of the present invention>> As shown in Figure 1, the house according to this embodiment has a floor-side recess 12 provided in the floor F (fixed floor) and a ceiling-side recess 14 provided in the ceiling C and located above the floor-side recess 12. Furthermore, the house is equipped with a drive mechanism that allows the movable floor 16 to be moved vertically and positioned inside the floor-side recess 12 and the ceiling-side recess 14.

[0020] The movable floor 16 consists of multiple square-shaped layers, each approximately the size of two tatami mats. Specifically, as shown in Figure 2, it is composed of multiple layers 16a to 16f that are stacked vertically. Each layer 16a to 16f is made of flooring material with a different purpose. For example, from the top, the movable floor 16 is composed of a layer 16a of flooring material for bedding, a carpet layer 16b, a cork layer 16c, a tatami mat layer 16d, a tile layer 16e suitable for dog runs and pet keeping, and an artificial turf layer 16f suitable for indoor golf. Furthermore, the types of flooring materials are not limited to these; for example, ornamental aquariums, soil, and rocks can also be used as flooring materials. In addition, the size and shape of each layer of the movable floor 16, as well as the order of each layer, are not limited to these; they can be combined and stacked in any size, shape, and order desired by the occupants.

[0021] Furthermore, as shown in Figures 2 to 4, the house is equipped with support members 20 that hold each layer 16a to 16f from all four sides. The support members 20 are configured so that the movable floor 16 is housed in a floor-side recess 12 and a ceiling-side recess 14, and can move in the vertical direction. Specifically, the support members 20 consist of a holding part 21 that holds the outer edges of each layer 16a to 16f from all four sides and places each layer 16a to 16f horizontally, and a wire connection part 22 to which a wire 24, which will be described later, is detachably connected.

[0022] The size of the area enclosed by the outer edge of the receiving member 20 is smaller than the openings of the floor-side recess 12 and the ceiling-side recess 14 in a plan view. However, the size of the area enclosed by the outer edge of the receiving member 20 is not limited to this, and may be the same size as the openings of the floor-side recess 12 and the ceiling-side recess 14. The size of the gap S formed between the end face of the movable floor 16 and the inner wall surface of the floor F is not particularly limited, as long as it is a size that allows the movable floor 16 to be smoothly housed in the floor-side recess 12 and the ceiling-side recess 14. For example, it is preferable to secure a gap of about 50 mm.

[0023] The floor-side recess 12 is a recess whose upper end opens toward the living space R. In this embodiment, when all the layers 16a to 16f constituting the movable floor 16 are accommodated, the floor surface 13B formed by the uppermost layer 16a of the movable floor 16 is positioned lower than the height of the floor surface 13A (see Figure 5(c)). Furthermore, as shown in Figures 1, 3, and 4, the floor F is provided with an edge member 23 that forms part of the peripheral edge 19 surrounding the floor-side recess 12 and is detachably attached to the floor F.

[0024] The edge member 23 can be removed from the peripheral edge 19 of the floor F, and when the movable floor 16 is housed in the floor-side recess 12, as shown in Figure 1, the lower end of the edge member 23 can be positioned so that it fits between the end face of the uppermost layer 16a and the inner wall surface of the floor-side recess 12. This allows the gap S formed between the end face of the movable floor 16 and the inner wall surface of the floor F to be sealed by the edge member 23.

[0025] The ceiling-side recess 14 is a recess whose lower end is open toward the living space R, and is configured such that when all layers 16a to 16f constituting the movable floor 16 are accommodated, the layer 16f, which is the lowest layer of the movable floor 16, is positioned higher than the height of the ceiling surface 15 (see Figure 5(a)).

[0026] The drive mechanism is capable of moving each of the multiple layers 16a to 16f that constitute the movable floor 16 in the vertical direction, and can position at least one of the multiple layers 16a to 16f in the ceiling-side recess 14 and the remaining layers in the floor-side recess 12. The drive mechanism according to this embodiment comprises a wire 24 and a winding machine 26 fixed to the ceiling C, as shown in Figure 1.

[0027] One end of the wire 24 is detachably connected to a wire connection part 22 provided at the corner of the receiving member 20 that holds the movable floor 16, and the other end is wound onto a winding machine 26. The user can manually remove the wire 24 from the wire connection part 22 and attach it to the wire connection part 22.

[0028] The winding machine 26 is located above the wire connection section 22 and can wind up or unwind the wire 24. The winding machine 26 is controlled by a control unit (not shown), which controls the winding machine 26 in response to user operations.

[0029] Next, with reference to Figures 5A and 5B, the operation of the drive mechanism of this embodiment and the movement flow of the movable floor associated with its operation will be described. As shown in Figure 5(a), when the cork layer 16c is used as the floor surface 13B, and the user operates the movable floor 16 to lower it, the control unit controls the winding machine 26 to unwind the wire 24, as shown in Figure 5(b), thereby lowering the layers 16a to 16f of the movable floor 16. As a result, each layer 16a to 16f of the movable floor 16 is temporarily housed in the floor recess 12, as shown in Figure 5(c).

[0030] Here, we consider a case where the user wants to set the movable floor 16 so that, for example, the cork layer 16c is the uppermost layer. In this case, the user manually detaches the wire connection parts 22 of the receiving members 20c to 20f that hold the cork layer 16c and the layers 16c to 16f below the cork layer 16c from the wire 24. Then, when the user operates to raise the layers 16a and 16b above the cork layer 16c, the control unit controls the winding machine 26 and winds up the wire 24 as shown in Figure 5(d). As a result, the movable floor 16 rises and is housed in the ceiling recess 14 as shown in Figure 5(e).

[0031] According to the present invention, the floor surface 13B can be easily changed according to the intended use of the floor. Specifically, it is possible to switch the flooring material used (i.e., the material constituting the floor surface 13B) from among several types of flooring materials, depending on the intended use of the floor. Therefore, the floor surface of a single room can be used for multiple purposes.

[0032] <<Regarding other embodiments>> Although one embodiment relating to the building of the present invention has been described above, the above embodiment is merely an example to facilitate understanding of the present invention and does not limit the present invention. In other words, the present invention can be modified and improved without departing from its spirit. Furthermore, it goes without saying that the present invention includes equivalents thereof.

[0033] Furthermore, other embodiments (modified versions) of the present invention that differ from the embodiments described above are conceivable. Modified versions will be described below. In the following, the differences from the embodiments described above will be the main focus, and common points will be omitted from the explanation.

[0034] (Variations of the receiving member) In the building according to the above embodiment, the movable floor 16 was moved vertically by connecting the wire 24 to wire connection parts 22 provided at the square of the receiving member 20 and winding or unwinding it with a winding machine 26. Furthermore, the area enclosed by the outer edge of the receiving member 20 was formed to be smaller in size than the openings of the floor-side recess 12 and the ceiling-side recess 14 in a plan view. However, it is not limited to this, and for example, if it is possible to move the receiving member 20 (and the movable floor 16) vertically without going through the wire connection parts 22 by a known method, a receiving member 30 having a size larger than the openings of the floor-side recess 12 and the ceiling-side recess 14 may be used, as shown in Figure 6(a).

[0035] The receiving member 30 has a long, slender, rod-shaped bent portion 28 instead of the wire connection portion 22. The bent portion 28 is a cantilever member that can be folded inward (towards the inside of the floor-side recess 12) via a hinge, and acts as a cushioning material to mitigate the impact generated when the receiving member 30 comes into contact with the floor-side recess 12 and the ceiling-side recess 14. Specifically, it is provided at each of the four ends of the holding portion 21, and as shown in Figure 6(b), it folds inward when it comes into contact with the inner wall surfaces of the floor-side recess 12 and the ceiling-side recess 14, respectively. Furthermore, since the bent portion 28 has a diameter larger than the gap S between the movable floor 16 and the inner wall surfaces of the floor-side recess 12 and the ceiling-side recess 14, it can close the gap S between the movable floor 16 and the inner wall surfaces of the floor-side recess 12 and the ceiling-side recess 14, as is clear from Figure 6(b).
