Embodiments for Carrying Out the Invention

[0019] The floor structure of the present invention will be described below with reference to the drawings.

[0020] The floor structure comprises a plurality of floor members laid on top of the foundation, and leg members erected on the foundation to support the floor members, with the plurality of floor members being supported by the leg members erected on the foundation to form a floor surface.

[0021] The floor member 1 includes, but is not limited to, four types of floor members 3, 4, 5, and 6 shown in Figures 1 to 5. The first floor member 3, as shown in Figure 1, includes a wooden rectangular (square) and board-shaped floor body 11 with a flat top surface, a wooden rectangular frame member 12 that is screwed to the bottom surface of the floor body 11 so as to protrude outward from the outer edge of one side of the floor body 11, and floor-side locking parts 13 attached to both longitudinal ends of the frame member 12.

[0022] As shown in Figure 2, the second floor member 4 comprises a wooden rectangular (square) and board-shaped floor body 11 with a flat top surface. As shown in Figure 3, the third floor member 5 comprises a wooden rectangular (square) and board-shaped floor body 11 with a flat top surface, two wooden rectangular frame members 12, 12 that are screwed to the underside of the floor body 11 so as to protrude outward from the outer edges of two adjacent sides in the circumferential direction of the floor body 11, and floor-side locking parts 13 that are attached to one longitudinal end of one frame member 12 and to the longitudinal end of the other frame member 12 adjacent to that end in the circumferential direction.

[0023] As shown in Figures 4 and 5, the fourth floor member 6 comprises a wooden rectangular (square) and board-shaped floor body 11 with a flat top surface, two wooden rectangular frame members 12, 12 that are screwed to the underside of the floor body 11 so as to protrude outward from the outer edges of two adjacent sides in the circumferential direction of the floor body 11, and floor-side locking parts 13, 13 attached to both longitudinal ends of each of these frame members 12, 12. The figure shows the state immediately before the floor-side locking parts 13, 13 of the fourth floor member 6 are placed on the mounting part 26.

[0024] As shown in Figure 5, the longitudinal length of the frame member 12 is shorter than the length of one side of the floor body 11. The floor-side locking portion 13 is made of metal and is attached to the lower surface of the frame member 12 with screws in a groove 12M formed therein. The depth of the groove 12M is set such that the frame member 12 and the screws B used to attach the frame member 12 are not exposed from the groove.

[0025] As shown in Figure 15, the floor-side locking portion 13 comprises a main body portion 13A that is screwed to the frame member 12 through through holes 13K, 13K, and a locking portion 13B that fits and locks onto the leg-side locking portion 261 of the leg member 2, which will be described later.

[0026] The main body 13A includes a flat plate portion 131 that abuts against the groove 12M of the frame member 12, and reinforcing portions 132, 132 at both ends of the plate portion 131 that are bent into a roughly U-shape to enhance shape retention. The locking portion 13B includes plate-shaped claw portions 133, 133 that extend upward from the upper end of the reinforcing portion 132 at the end of the plate portion 131 opposite to the side attached to the frame member 12. The claw portions 133, 133 are configured in an inclined position that widens outward towards the upper end. In addition, the end faces 133a, 133a of each claw portion 133, 133 on the frame member 12 side abut against the end face 12T of the frame member 12 (see Figure 1). This prevents the claw portions 133, 133 from bending when a load is applied to the floor-side locking portion 13 from above.

[0027] As shown in Figures 6 to 8, the leg member 2 comprises a ground contact portion 21 with a roughly square shape that contacts the upper surface of the foundation S, a lower shaft portion 22 connected to the ground contact portion 21 with its lower end secured, a rectangular tubular member 23 into which the upper end of the lower shaft portion 22 is inserted from the lower end, an upper shaft portion 24 inserted into the rectangular tubular member 23 from the upper end, a receiving member 25 with a roughly square shape and plate-like form connected to the upper end of the upper shaft portion 24 with its upper end secured, and a mounting portion 26 fixed to the upper surface of the receiving member 25 on which the floor-side locking portions 13 of the frame members 12 of the floor members 1 can be placed.

[0028] A male threaded portion 22A is formed on the outer surface of the lower shaft portion 22, and a female threaded portion 23A is formed on the inner surface of the lower end of the rectangular tubular member 23 facing the male threaded portion 22A. By rotating the rectangular tubular member 23, the lower shaft portion 22 can move vertically relative to the rectangular tubular member 23, allowing for height adjustment. At this time, the nut N1 screwed onto the lower shaft portion 22 should be loosened. Similarly, a male threaded portion 24A is formed on the outer surface of the upper shaft portion 24, and a female threaded portion 23B is formed on the inner surface of the upper end of the rectangular tubular member 23 facing the male threaded portion 24A. By rotating the rectangular tubular member 23, the upper shaft portion 24 can move vertically relative to the rectangular tubular member 23, allowing for height adjustment. At this time, the nut N2 screwed onto the upper shaft portion 24 should be loosened. Here, the leg member 2 is provided with adjustment parts at two locations, upper and lower, to adjust the height of the mounting portion 26, but it may be provided with only one location.

[0029] The mounting section 26 is provided with multiple leg-side locking sections 261 into which the floor-side locking section 13 engages and locks. The mounting section 26 is made of synthetic resin (it may also be made of metal, wood, etc.) and has a roughly square shape. It has columnar sections 262 that protrude upward from each of the four corners, and a square projection 263 in the center that is lower than the columnar sections 262. As shown in Figure 9, the plate section 131 is supported by the projection section 2611 (a section that is thicker than the other parts), which will be described later, and the lower surface of the corner of the floor member 1 is supported on the columnar sections 262, thereby preventing deformation or damage to the mounting section 26.

[0030] The leg-side locking portions 261 are provided in pairs facing each other in the left-right direction perpendicular to the vertical direction, and in pairs facing each other in the front-rear direction perpendicular to both the vertical and left-right directions. Specifically, the leg-side locking portions 261 are provided between adjacent columnar portions 262, 262 in the circumferential direction, and each leg-side locking portion 261 includes a projection 2611 that extends in the longitudinal direction of the frame member 12 so as to project upward from the bottom of the mounting portion 26 and contact and receive the plate portion 131 of the floor-side locking portion 13 from below, and a pair of locking bodies 2612, 2612 that are provided so as to extend upward on both sides in the width direction perpendicular to the longitudinal direction of the projection 2611. The projection 2611 has an upper surface for receiving the plate portion 131, and recesses 2611A, 2611A are formed on both sides in the width direction into which the inner portions of the reinforcing portions 132, 132 fit.

[0031] As shown in Figures 8 and 9, the locking bodies 2612, 2612 are configured in an inclined position where they are closer to each other towards the upper end, and are equipped with claw locking parts 2612A, 2612A at their tips, which engage with the claw parts 133, 133 of the floor-side locking part 13.

[0032] The locking bodies 2612, 2612 have an opening width at their upper end that is smaller than the width between the upper ends of the claws 133, 133 of the floor-side locking portion 13, and the claws 133, 133 of the floor-side locking portion 13 push and spread the claw locking portions 2612A, 2612A from above, and fit between the claw locking portions 2612A, 2612A. In this fitted state, the elastic restoring force of the claw locking portions 2612A, 2612A toward the side approaching each other biases the claw locking portions 2612A, 2612A to contact the claws 133, 133 located inside them from above and below. Figure 8 shows the state in which the three floor-side locking portions 13, 13, 13 are fitted and locked together with the three leg-side locking portions 261, 261, 261. Note that in Figure 8, the frame member 12 to which the three floor-side locking parts 13, 13, 13 are attached, and the floor body 11 to which the frame member 12 is attached, are omitted.

[0033] Figure 11 shows the floor surface formed using the 12 floor members 1 and 6 leg members 2 configured as described above. Figure 12 is a bottom view of Figure 11, seen from below.

[0034] The procedure for forming the floor surface will be explained with reference to Figures 13 and 14. First, as shown in Figure 13(a), the first leg member 2 is fixed to the foundation S with adhesive (screws may also be used), using the marking lines (not shown) on the foundation surface as a guide. Next, the lower surfaces of the left and front sides of the first third floor member 5 are placed on the left corner at the front of the base 7, and the floor-side locking parts 13, 13 of the frame members 12, 12 attached to the lower surfaces of the remaining rear and right sides of the third floor member 5 are fitted and locked from above to the leg-side locking parts 261, 261 of the leg member 2 (see Figure 6), thereby fixing the third floor member 5 to the leg member 2.

[0035] After fixing, the second leg member 2 is fixed to the foundation S with adhesive, as shown in Figure 13(b), using the marking lines (not shown) on the foundation surface as a guide. Next, the second third floor member 5 is placed to the right of the first third floor member 5. At this time, the front edge of the third floor member 5 is placed on the base 7, and the left edge of the second third floor member 5 is placed on the right frame member 12 of the first third floor member 5 that was installed earlier. Then, the floor-side locking parts 13, 13 of the placed second third floor member 5 are fitted and locked into the leg-side locking parts 261, 261 (see Figure 6) of the second leg member 2, thereby fixing the second third floor member 5 to the leg member 2.

[0036] After fixing, the third leg member 2 is fixed to the foundation S with adhesive, as shown in Figure 13(c), using the marking lines (not shown) on the foundation surface as a guide. Next, the front and right sides of the third floor member 5 are placed on the right corner of the front side of the base 7, and the floor-side locking parts 13, 13 of the frame members 12, 12 attached to the remaining two sides (left and rear sides) of the third floor member 5 are fitted and locked from above to the leg-side locking parts 261, 261 of the leg member 2 (see Figure 6), thereby fixing the third floor member 5 to the leg member 2.

[0037] Next, as shown in Figure 14(a), the first floor member 3 is placed between the second third floor member 5 from the left and the fourth third floor member 5 from the left (rightmost). At this time, the front edge of the first floor member 3 is placed on the base, the left edge of the first floor member 3 is placed on the right frame member 12 of the second third floor member 5 from the left, and the right edge of the first floor member 3 is placed on the left frame member 12 of the third third floor member 5 from the left. Then, the floor-side locking portion 13 at the left end of the frame member 12 of the first floor member 3 is fitted and locked from above onto the leg-side locking portion 261 (see Figure 6) of the second leg member 2 from the left, and the floor-side locking portion 13 at the right end of the frame member 12 of the first floor member 3 is fitted and locked from above onto the leg-side locking portion 261 (see Figure 6) of the third leg member 2 from the left, thereby fixing the first floor member 3 to the second and third leg members 2,2 from the left (see Figure 14(b)).

[0038] After fixing the first floor member 3, the central row in the front-to-back direction is installed in the same way as the front row, with three leg members 2, three third floor members 5, and one first floor member 1. Next, in the rear row in the front-to-back direction, three first floor members 3 and one second floor member 4 are installed, forming the floor surface shown in Figure 11. Once the installation of the floor members is complete, the floor members are connected to each other with screws (or nails). Specifically, screws (or nails) are driven into the mounting portion of the floor member 1 that is placed on the frame member 12 of the floor member 1, so as to reach the frame member 12, and the floor members are connected to each other. In this embodiment, the case of mounting on a foundation has been described, but it may also be the case of installation inside the foundation.

[0039] Furthermore, the floor member 1 of the present invention is a floor member 1 that forms a floor structure by being supported by leg members 2 erected on a foundation, the leg members 2 have a mounting portion 26 on which a plurality of floor members 1 can be placed, the mounting portion 26 has a plurality of leg-side locking portions 261, the floor member 1 comprises a floor body 11 whose upper surface is the floor surface, and a floor-side locking portion 13 that can be fitted and locked to the leg-side locking portion 261, and is configured to be locked to the mounting portion 26 by the floor-side locking portion 13 fitting and locking to the leg-side locking portion 261 when the floor member 1 is placed on the mounting portion 26.

[0040] With the above configuration, when the floor member 1 is placed on the mounting section 26, the floor-side locking section 13 engages with and locks into the leg-side locking section 261, thereby locking the floor member 1 to the mounting section 26. This allows for easy installation.

[0041] Furthermore, the leg member 2 of the present invention is a leg member 2 that forms a floor structure by supporting a plurality of floor members 1 laid on top of a foundation, wherein the floor member 1 comprises a plate-shaped floor body 11 whose upper surface is the floor surface and a floor-side locking portion 13, the leg member 2 comprises a mounting portion 26 on which a plurality of floor members 1 can be placed, the mounting portion 26 comprises a plurality of leg-side locking portions 261 into which the floor-side locking portion 13 fits and locks, and the floor member 1 is locked to the mounting portion 26 by the floor-side locking portion 13 and the leg-side locking portion 261 fitting and locking when the floor member 1 is placed on the mounting portion 26.

[0042] With the above configuration, when the floor member 1 is placed on the mounting section 26, the floor-side locking section 13 and the leg-side locking section 261 engage and lock together, thereby locking the floor member 1 to the mounting section 26. This allows for easy installation.

[0043] Furthermore, the present invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention.

[0044] In the above embodiment, when installing the four front floor members, the fourth floor member from the left was installed first, followed by the third floor member from the left. However, the order of installation is not limited to this and can be freely changed.

[0045] Furthermore, although four leg-side locking parts were provided in the above embodiment, any number of parts, such as two, three, or five or more, may be provided.

[0046] Furthermore, in the above embodiment, the floor-side locking portion was fitted into the leg-side locking portion to lock it in place, but conversely, the leg-side locking portion may be fitted into the floor-side locking portion to lock it in place.

[0047] Furthermore, in the above embodiment, there was a configuration in which one floor-side locking portion provided on the floor member and one leg-side locking portion provided on the leg member fit together and lock. However, there may also be a configuration in which multiple (any number of two or more) floor-side locking portions provided on the floor member and multiple (any number of two or more) leg-side locking portions provided on the leg member fit together and lock.
