[0043] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0044] In the present specification and each drawing, the same reference numerals are given to the same elements as those in the conventional drawings, and detailed descriptions thereof are appropriately omitted.

[0045] (First Embodiment)

[0046] Figure 1 It is a schematic perspective view illustrating a floor device and a bed device according to the first embodiment.

[0047] like Figure 1 As shown, the bottom plate device 170 of the embodiment is used for the bed device 310. For example, the bed device 310 includes the bottom plate device 170 and a frame 70F.

[0048] For example, the base plate device 170 is provided on the frame 70F. The base plate device 170 is fixed to the frame 70F.

[0049] The base plate device 170 includes, for example, a first base plate 10. The base plate device 170 may also include a second base plate 20. The first base plate 10 and the second base plate 20 are fixed to the frame 70F.

[0050] The first bottom plate 10 is, for example, at least a portion of a back bottom plate. The second bottom plate 20 is, for example, at least a portion of a foot bottom plate. The second bottom plate 20 may also include, for example, a knee bottom plate. The second bottom plate 20 may also include, for example, a waist bottom plate.

[0051] The second bottom plate 20 can be connected to the first bottom plate 10. In this example, a deformable portion 25 of the second bottom plate 20 is provided on a portion of the first bottom plate 10. A portion of the first bottom plate 10 and the deformable portion 25 are connected to each other.

[0052] The direction from the head to the foot of the bed 70B is set as the X-axis direction. The left-right direction of the bed 70B is set as the Y-axis direction. The height direction of the bed 70B is set as the Z-axis direction. For example, the direction from the first bottom plate 10 to the second bottom plate 20 is along the X-axis direction.

[0053] like Figure 1 As shown, the first bottom plate 10 includes a first portion 11 and a second portion 12. The second bottom plate 20 includes a third portion 23 and a fourth portion 24.

[0054] In one state, the direction from the second part 12 to the first part 11 is along the first direction. The first direction corresponds to the X-axis direction. For example, the first direction is along the up-down direction of the bed 70B. In one state, the direction from the third part 23 to the fourth part 24 is along the first direction (X-axis direction).

[0055] As described below, the first bottom plate 10 has a plurality of states. In different states, the relative positions of the first portion 11 and the second portion 12 change. As a result, the length of the first bottom plate 10 changes. The second bottom plate 20 has a plurality of states. In different states, the relative positions of the third portion 23 and the fourth portion 24 change. As a result, the length of the second bottom plate 20 changes. Examples of these states are described below.

[0056] Figure 2 (a) and Figure 2 (b) is a schematic side view illustrating the base device and the bed device according to the first embodiment.

[0057] like Figure 2 As shown in (a), the first base plate 10 is in the first state ST1. Figure 2 As shown in (b), the first base plate 10 is in the second state ST2. Figure 2 As shown in (a), the second base plate 20 is in the third state ST3. Figure 2 As shown in (b), the second base plate 20 is in the fourth state ST4.

[0058] In the first state ST1, the direction from the second portion 12 to the first portion 11 is along the X-axis direction. In the first state ST1, the first portion 11 is between the second portion 12 and the second bottom plate 20 in the first direction (X-axis direction).

[0059] like Figure 2 As shown in (b), in the second state ST2, the direction from the first portion 11 to the second portion 12 is along the Z-axis direction. The length of the first bottom plate 10 in the second state ST2 is shorter than the length of the first bottom plate 10 in the first state ST1.

[0060] In the third state ST3, the direction from the third portion 23 to the fourth portion 24 is along the X-axis direction. Figure 2 As shown in (b), in the fourth state ST4, the direction from the third portion 23 to the fourth portion 24 is along the Z-axis direction. The length of the second bottom plate 20 in the fourth state ST4 is shorter than the length of the second bottom plate 20 in the third state ST3.

[0061] The base plate device 170 has a long state ST01 and a short state ST02. For example, in the long state ST01, the first base plate 10 is in the first state ST1 and the second base plate 20 is in the third state ST3. In the short state ST02, the first base plate 10 is in the second state ST2 and the second base plate 20 is in the fourth state ST4.

[0062] The length of the bottom plate device 170 changes according to the length of the first bottom plate 10 and the length of the second bottom plate 20. For example, the length L01 of the bottom plate device 170 in the long state ST01 is longer than the length L02 of the bottom plate device 170 in the short state ST02. The lengths are, for example, the lengths along the X-axis direction.

[0063] According to the embodiment, a base device whose length can be easily changed can be provided. The appropriate size (length) of the base device depends on the height of the user of the bed 70B, etc. The appropriate size (length) of the base device sometimes depends on the size of the room. In the embodiment, the length of the base device can be easily changed according to the usage conditions. According to the embodiment, a more convenient base device and bed device can be provided.

[0064] Hereinafter, an example of the first base plate 10 will be described.

[0065] Figure 3 It is a schematic perspective view illustrating a part of the floor device according to the first embodiment.

[0066] Figure 4 (a) and Figure 4 (b) is a schematic cross-sectional view illustrating the floor device and the bed device according to the first embodiment.

[0067] Figure 4 (a) and Figure 4 (b) is a cross-sectional view based on the X-Z plane.

[0068] Figure 3 The first bottom plate 10 in the first state ST1 is illustrated. In the first state ST1, the second portion 12 is aligned with the first portion 11 in the X-axis direction. In this state, the length of the first bottom plate 10 (first length L1) corresponds to the length along the X-axis direction between the two ends (end 10E and end 10F) of the first bottom plate 10. The direction from the end 10F to the end 10E is along the X-axis direction.

[0069] In this example, the second part 12 is connected to the first part 11 via the first connection part 10c. The first connection part 10c is set as a substantial axis, and the second part 12 can rotate. By rotating the second part 12, the second part 12 is located on the first part 11. This state corresponds to the second state ST2.

[0070] like Figure 4 As shown in (a), the first part 11 includes a first surface 11a and a second surface 11b. The first surface 11a is, for example, a lower surface. The second surface 11b is an upper surface. The second part 12 includes a third surface 12c and a fourth surface 12d. In the first state ST1, the third surface 12c corresponds to, for example, the lower surface. In the first state ST1, the fourth surface 12d corresponds to the upper surface.

[0071] For example, in the first state ST1, the first surface 11a is opposed to the first frame portion 70Fa of the frame 70F. The first surface 11a is located between the first frame portion 70Fa and the second surface 11b.

[0072] In the first state ST1, the third surface 12c is opposed to the second frame portion 70Fb of the frame 70F. The third surface 12c is located between the second frame portion 70Fb and the fourth surface 12d.

[0073] like Figure 4As shown in (b), in the second state ST2, the first surface 11a is between the frame 70F and the third surface 12c. The second surface 11b is between the first surface 11a and the third surface 12c. The fourth surface 12d is between the second surface 11b and the third surface 12c. In the second state ST2, the third surface 12c is the upper surface, and the fourth surface 12d is the lower surface.

[0074] In the first state ST1, the direction from the second portion 12 to the first portion 11 is along the first direction (X-axis direction). The first length L1 of the first bottom plate 10 along the first direction in the first state ST1 is longer than the second length L2 of the first bottom plate 10 in the second state ST2.

[0075] By folding the second part 12, the second part 12 is located on the first part 11. Thus, the first state ST1 can be easily switched to the second state ST2. By rotating the second part 12, the second part 12 moves from the position on the first part 11. Thus, the second state ST2 can be easily switched to the first state ST1. The length can be easily changed.

[0076] Thus, in the first state ST1 of the first base plate 10, the direction from the second portion 12 to the first portion 11 is along the first direction. The direction from the third surface 12c to the first surface 11a in the first state ST1 is along the first direction. The direction from the fourth surface 12d to the second surface 11b in the first state ST1 is along the first direction. For example, the first direction is the X-axis direction.

[0077] The direction from the third surface 12c to the fourth surface 12d in the first state ST1 is along the second direction intersecting the first direction. For example, the second direction is perpendicular to the first direction. The second direction is, for example, the Z-axis direction. The second direction is, for example, the height direction of the bed 70B. The direction from the first surface 11a to the second surface 11b in the first state ST1 is along the second direction.

[0078] In the second state ST2 of the first bottom plate 10, the second surface 11b is located between the first surface 11a and the third surface 12c. In the second state ST2, the fourth surface 12d is located between the second surface 11b and the third surface 12c.

[0079] For example, the second part 12 is continuous with the first part 11. In this example, the first part 11 and the second part 12 are connected to each other by the first connecting portion 10c. The first connecting portion 10c can also be regarded as a part of the first part 11. The first connecting portion 10c can also be regarded as a part of the second part 12. The first part 11, the second part 12 and the first connecting portion 10c can also be formed by integral molding.

[0080] For example, in the second state ST2, the second portion 12 overlaps the first portion 11 in the second direction (the height direction of the bed 70B, i.e., the Z-axis direction). In the first state ST1, the second portion 12 does not overlap the first portion 11 in the second direction. The relative positional relationship between the first portion 11 and the second portion 12 changes by rotating. The length of the first base plate 10 can be easily changed.

[0081] like Figure 4 (a) and Figure 4 As shown in (b), the length of the frame 70F in the first direction (X-axis direction) may also be variable. For example, the second frame portion 70Fb may slide relative to the first frame portion 70Fb. Thus, the position of the second frame portion 70Fb relative to the first frame portion 70Fa changes.

[0082] For example, the second frame portion 70Fb has a long hole 70Fh. The long hole 70Fh extends in the X-axis direction. The second frame portion 70Fb is fixed to the first frame portion 70Fa by a pin 70Fp through the long hole 70Fh. By changing the position of the long hole 70Fh into which the pin 70Fp is inserted, the length of the frame 70F along the X-axis direction can be changed. Alternatively, the long hole 70Fh may be provided in the first frame portion 70Fa, and the first frame portion 70Fa and the second frame portion 70Fb may be fixed to each other by the pin 70Fp through the long hole 70Fh.

[0083] like Figure 3 As shown, in the first state ST1, the width W12 of the second portion 12 decreases in the direction from the first portion 11 to the second portion 12. The width W12 corresponds to the length of the second portion 12 in the third direction. The third direction intersects a plane including the first direction and the second direction. The third direction is, for example, the Y-axis direction.

[0084] For example, in the first state ST1, the width W12 decreases from the first portion 11 toward the end of the second portion 12. As a result, the edge of the end of the first base plate 10 is inclined in the X-Y plane. With such a shape, the corner of the first base plate 10 in the first state ST1 is inclined. As a result, it is possible to prevent the user or caregiver of the bed device 310 from touching the corner.

[0085] Figure 5 (a) and Figure 5 (b) is a schematic cross-sectional view illustrating a part of the floor device according to the first embodiment.

[0086] These figures are cross-sectional views based on the X-Z plane. Figure 4 (a) and Figure 4 (b) Different cross sections.

[0087] like Figure 5(a) and Figure 3 As shown, for example, the first portion 11 may also include a concave region 11D. The second portion 12 may also include a convex region 12P. Figure 5 As shown in (b), in the second state ST2, the convex region 12P enters the concave region 11D. For example, the second portion 12 is stably embedded in the first portion 11.

[0088] like Figure 5 As shown in (a), a first thickness d1 of at least a portion of the first portion 11 along the second direction (height direction, i.e., Z-axis direction) may be thinner than a second thickness d2 of at least a portion of the second portion 12 along the second direction (height direction, i.e., Z-axis direction). For example, in the second state ST2, the thin portion of the first portion 11 may also overlap with the thick portion of the second portion 12.

[0089] For example, in the first state ST1, by providing the convex region 12P on the second portion 12, when the mattress is placed on the second portion 12, the mattress is supported by the convex region 12P. The mattress can be easily flattened.

[0090] like Figure 5 As shown in (a), the first portion 11 includes a first concavo-convex portion 11A. The second portion 12 includes a second concavo-convex portion 12A. In this example, the first concavo-convex portion 11A is a convex portion, and the second concavo-convex portion 12A is a concave portion.

[0091] like Figure 5 As shown in (b), in the second state ST2, the first concavo-convex part 11A and the second concavo-convex part 12A are meshed with each other. Thus, in the second state ST2, the position of the second part 12 relative to the first part 11 becomes stable. For example, in the second state ST2, the height of the upper surface (third surface 12c) of the second part 12 is substantially the same as the height of the upper surface of the first part 11. It is easy to obtain a flat upper surface.

[0092] Hereinafter, an example of the second base plate 20 will be described.

[0093] Figure 6 It is a schematic perspective view illustrating a part of the floor device according to the first embodiment.

[0094] Figure 7 (a) and Figure 7 (b) is a schematic cross-sectional view illustrating the floor device and the bed device according to the first embodiment.

[0095] Figure 7 (a) and Figure 7 (b) is a cross-sectional view based on the X-Z plane.

[0096] Figure 6The second bottom plate 20 in the fourth state ST4 is illustrated. In the fourth state ST4, the fourth portion 24 is aligned with the third portion 23 in the X-axis direction. In this state, the length of the second bottom plate 20 (the fourth length L4) corresponds to the length along the X-axis direction between the two ends (the end 20E and the end 20F) of the second bottom plate 20. The direction from the end 20E to the end 20F is along the X-axis direction.

[0097] In this example, the fourth portion 24 is connected to the third portion 23 via the second connecting portion 20c (see Figure 7 (a) and Figure 7 (b)) The second connection part 20c is set as a substantial axis, and the fourth part 24 can rotate. By the rotation of the fourth part 24, the fourth part 24 is located on the third part 23. This state corresponds to the fourth state ST4.

[0098] like Figure 7 As shown in (a), the third part 23 includes a fifth surface 23e and a sixth surface 23f. The fifth surface 23e is, for example, a lower surface. The sixth surface 23f is an upper surface. The fourth part 24 includes a seventh surface 24g and an eighth surface 24h. In the third state ST3, the seventh surface 24g corresponds to, for example, the lower surface. In the third state ST3, the eighth surface 24h corresponds to the upper surface.

[0099] For example, in the third state ST3, the fifth surface 23e is opposed to the third frame portion 70Fc of the frame 70F. In the third state ST3, the fifth surface 23e is located between the third frame portion 70Fc and the sixth surface 23f.

[0100] In the third state ST3, the seventh surface 24g is opposed to the fourth frame portion 70Fd of the frame 70F. In the third state ST3, the seventh surface 24g is located between the fourth frame portion 70Fd and the eighth surface 24h.

[0101] like Figure 7 As shown in (b), in the fourth state ST4, the fifth surface 23e is between the frame 70F and the seventh surface 24g. The sixth surface 23f is between the fifth surface 23e and the seventh surface 24g. The eighth surface 24h is between the sixth surface 23f and the seventh surface 24g. In the fourth state ST4, the seventh surface 24g is the upper surface and the eighth surface 24h is the lower surface.

[0102] In the third state ST3, the direction from the third portion 23 to the fourth portion 24 is along the first direction (X-axis direction). The third length L3 of the second bottom plate 20 along the first direction (X-axis direction) in the third state ST3 is longer than the fourth length L4 of the second bottom plate 20 in the fourth state ST4.

[0103] For example, by folding the fourth part 24, the fourth part 24 is located on the third part 23. Thus, the third state ST3 can be easily switched to the fourth state ST4. By rotating the fourth part 24, the fourth part 24 moves from the position on the third part 23. Thus, the fourth state ST4 can be easily switched to the third state ST3. The length can be easily changed.

[0104] As described above, in the third state ST3 of the second base plate 20, the direction from the third portion 23 to the fourth portion 24 is along the first direction (e.g., the X-axis direction). The direction from the fifth surface 23e to the seventh surface 24g in the third state ST3 and the direction from the sixth surface 23f to the eighth surface 24h in the third state ST3 are along the first direction. The direction from the fifth surface 23e to the sixth surface 23f in the third state ST3 and the direction from the seventh surface 24g to the eighth surface 24h in the third state ST3 are along the second direction (e.g., the Z-axis direction). In the fourth state ST4 of the second base plate 20, the direction from the third portion 23 to the fourth portion 24 is along the second direction. In the fourth state ST4, the sixth surface 23f is between the fifth surface 23e and the seventh surface 24g. In the fourth state ST4, the eighth surface 24h is between the sixth surface 23f and the seventh surface 24g.

[0105] For example, the fourth portion 24 is continuous with the third portion 23. In this example, the third portion 23 and the fourth portion 24 are connected by the second connecting portion 20c (see Figure 7 (a) and Figure 7 (b)) are connected to each other. The second connecting portion 20c can also be regarded as a part of the third portion 23. The second connecting portion 20c can also be regarded as a part of the fourth portion 24. The third portion 23, the fourth portion 24 and the second connecting portion 20c can be formed by integral molding.

[0106] like Figure 7 As shown in (b), in the fourth state ST4, the fourth portion 24 overlaps the third portion 23 in the second direction (the height direction, i.e., the Z-axis direction). Figure 7 As shown in (a), in the third state ST3, the fourth portion 24 does not overlap with the third portion 23 in the second direction.

[0107] For example, the fourth frame portion 70Fd is slidable relative to the third frame portion, so that the position of the fourth frame portion 70Fd with respect to the third frame portion 70Fc changes.

[0108] For example, the fourth frame portion 70Fd has a long hole 70Fi. The long hole 70Fi extends in the X-axis direction. The fourth frame portion 70Fd is fixed to the third frame portion 70Fc via the long hole 70Fi by a pin 70Fq. By changing the position of the long hole 70Fi into which the pin 70Fq is inserted, the length of the frame 70F along the X-axis direction can be changed. Alternatively, the third frame portion 70Fc is provided with a long hole 70Fi, and the third frame portion 70Fc and the fourth frame portion 70Fd are fixed to each other via the long hole 70Fi by a pin 70Fq.

[0109] like Figure 6 , Figure 7 (a) and Figure 7 As shown in (b), the third portion 23 may also include a receding portion 23R. The receding portion 23R recedes along the first direction (X-axis direction). Figure 7 As shown in (b), in the fourth state ST4, a gap 23G is formed between the receding portion 23R and the fourth portion 24. The length of the gap 23G along the first direction (X-axis direction) is, for example, 2 mm or more. By inserting a tool or the like into the gap 23G and operating it, it is easy to rotate the fourth portion 24 from a position overlapping with the third portion 23. The length of the gap 23G along the first direction (X-axis direction) can also be 8 mm or more. For example, by providing such a gap 23G, an operator or the like can easily put his hand into the gap 23G and rotate the fourth portion 24 from a position overlapping with the third portion 23. The transition from the fourth state ST4 to the third state ST3 becomes easier. In the first base plate 10 (for example, at least a portion of the back base plate), a receding portion can also be provided in the same manner as the second base plate 20 (for example, at least a portion of the foot base plate).

[0110] Figure 8 (a) and Figure 8 (b) is a schematic cross-sectional view illustrating a part of the floor device according to the first embodiment.

[0111] Figure 8 (a) and Figure 8 (b) is a cross-sectional view based on the X-Z plane. Figure 8 (a) and Figure 8 (b) illustrates the Figure 7 (a) and Figure 7 (b) Different cross sections.

[0112] like Figure 8 As shown in (a), for example, the third portion 23 may also include a concave region 23D. The fourth portion 24 may also include a convex region 24P. Figure 8 As shown in (b), in the fourth state ST4, the convex region 24P enters the concave region 23D. For example, the fourth portion 24 is stably embedded in the third portion 23.

[0113] like Figure 8 As shown in (a), the third portion 23 includes a third concavo-convex portion 23A. The fourth portion 24 includes a fourth concavo-convex portion 24A. In this example, the third concavo-convex portion 23A is a convex portion, and the fourth concavo-convex portion 24A is a concave portion.

[0114] like Figure 8 As shown in (b), in the fourth state ST4, the third concavo-convex part 23A and the fourth concavo-convex part 24A are meshed with each other. Thus, in the fourth state ST4, the position of the fourth part 24 relative to the third part 23 becomes stable. For example, in the fourth state ST4, the height of the upper surface (seventh surface 24g) of the fourth part 24 is substantially the same as the height of the upper surface of the third part 23. It is easy to obtain a flat upper surface.

[0115] Fig. 9 (a)~ Fig. 9 (e) is a schematic diagram illustrating a part of the floor device according to the first embodiment.

[0116] Fig. 9 (a)~ Fig. 9 (d) is a perspective view of the first bottom plate 10 as viewed from the back side (for example, the first surface 11 a side).

[0117] like Fig. 9 As shown in (b), the first base plate 10 may also include a fixing member 15. In the first state ST1, the fixing member 15 fixes the first part 11 and the second part 12. For example, the fixing member 15 fixes the first part 11 and the second part 12 from the back side. In this example, one end of the fixing member 15 is fixed to the first part 11 by a first screw member 15a. The other end of the fixing member 15 is fixed to the second part 12 by a second screw member 15b. The positions of the first part 11 and the second part 12 are fixed by the fixing member 15. As a result, in the first state ST1, the first part 11 and the second part 12 become flat.

[0118] like Fig. 9 As shown in (c), in the second state ST2, both ends of the fixing member 15 are fixed to the first portion 11.

[0119] For example, Fig. 9 As shown in (d), in the first state ST1 and the second state ST2, the fixed position of the second threaded member 15b is different. In the second state ST2, the second threaded member 15b is inserted into the hole 11h of the first part 11. In the first state ST1, the second threaded member 15b is inserted into the hole 12h of the second part 12.

[0120] like Fig. 9As shown in (e), the angle between the first part 11 and the second part 12 can be fixed by a fixing component 15.

[0121] In the embodiment, the mattress is placed on the bottom plate device 170. When the mattress is placed, a component for fixing the position of the mattress may be provided. An example of such a component will be described below.

[0122] like Figure 1 and Figure 6 As shown, the second bottom plate 20 may also include a protruding member 20M. The protruding member 20M protrudes upward from the third portion 23 or the fourth portion 24. The protruding member 20M is inserted into a hole provided in the third portion 23 or the fourth portion 24 and is fixed to the third portion 23 or the fourth portion 24. For example, the protruding member 20M may be used for both the side and the foot side.

[0123] Fig.10 (a)~ Fig.10 (c) is a schematic diagram illustrating a part of the floor device according to the first embodiment.

[0124] Fig.11 (a)~ Fig.11 (c) is a schematic diagram illustrating a part of the floor device according to the first embodiment.

[0125] like Fig.10 (a) and Fig.11 As shown in (a), the third portion 23 includes a third hole 23H. The fourth portion 24 includes a fourth hole 24H. Fig.10 (b) and Fig.11 As shown in (a), in the third state ST3, the lower portion of the protruding member 20M is inserted into and fixed in the fourth hole 24H.

[0126] like Fig.10 As shown in (c), in the fourth state ST4, the lower portion of the protruding member 20M reaches the third hole 23H via the fourth hole 24H. For example, in the fourth state ST4, at least a portion of the third hole 23H overlaps with the fourth hole 24H. In the fourth state ST4, the protruding member 20M can pass through the fourth hole 24H and be inserted into the third hole 23H to be fixed to the third portion 23 and the fourth portion 24.

[0127] like Fig.10 (b) and Fig.11 As shown in (a), in the third state ST3, the protruding member 20M can be inserted into the fourth hole 24H and fixed to the fourth portion 24. One protruding member 20M can be used in both the third state ST3 and the fourth state ST4.

[0128] like Fig.11As shown in (b), in the third state ST3, the fourth hole 24H does not overlap with the third portion 23. Fig.10 As shown in (c), in the fourth state ST4, the fourth hole 24H overlaps with the third portion 23, and at least a portion of the fourth hole 24H overlaps with the third hole 23H.

[0129] like Fig.11 As shown in (c), the seventh surface 24g of the fourth portion 24 may also include a convex portion 24gp. Due to the provision of the convex portion 24gp, the length of the protruding member 20M inserted into the hole in the fourth state ST4 becomes substantially the same as the length of the protruding member 20M inserted into the hole in the third state ST3 (see Fig.10 (b) and Fig.10 (c)). The mattress fixing hole on the foot side can be inserted from either the top or bottom (front or back). Since the mattress fixing hole on the foot side is a resin molded product, one side may become tight or loose due to the influence of the draft angle. By setting the inclination of the mattress fixing hole to 0 degrees, a stable fixing state can be obtained regardless of which side is inserted from, the front or back. The portion with the inclination set to 0 degrees can be set in a portion of the mattress fixing hole. Ribs can also be set on a portion of the side of the protruding part 20M inserted into the mattress fixing hole.

[0130] Fig.12 (a)~ Fig.12 (d) is a schematic diagram illustrating a part of the floor device according to the first embodiment.

[0131] Fig.13 (a) and Fig.13 (b) is a schematic perspective view illustrating a part of the floor device according to the first embodiment.

[0132] Fig.13 (b) Yes Fig.13 (a) A1-A2 line cross-sectional view.

[0133] like Fig.12 As shown in (a), the third part 23 and the fourth part 24 may also be formed parallel to each other (horizontally). In this case, the distance between the third part 23 and the fourth part 24 becomes longer, and sometimes the fourth part 24 tends to rotate excessively downward. As a result, sometimes a reverse tilt occurs. In this case, Fig.12 As shown in (d), the rotation of the fourth portion 24 may be restricted by an insertion member 20X.

[0134] For example, Fig.12 As shown in (b), a gap 20G is provided between a portion of the third portion 23 and a portion of the fourth portion 24. Fig.12 (c) Fig.13 (a) and Fig.13 As shown in (b), in the third state ST3, the insertion member 20X is inserted into the gap 20G.

[0135] like Fig.12 (d) and Fig.13 As shown in (b), the insertion member 20X is fixed so as to engage with the gap 20G. The rotation of the fourth portion 24 is restricted by the insertion member 20X, thereby suppressing the occurrence of reverse tilt.

[0136] Fig.14 (a) and Fig.14 (b) is a schematic perspective view illustrating a part of the floor device according to the first embodiment.

[0137] like Fig.14 As shown in (a), a mark 23M may be provided on the sixth surface 23f of the third portion 23. In this example, the mark 23M is the letter "R". The letter "R" means "regular", for example. In the third state ST3, the sixth surface 23f is exposed. By providing the mark 23M on the exposed surface, it is easy to understand that it is in the "regular" state.

[0138] like Fig.14 As shown in (b), a mark 24M may be provided on the seventh surface 24g of the fourth portion 24. In this example, the mark 24M is the letter "M". The letter "M" means "mini", for example. In the fourth state ST4, the seventh surface 24g becomes the upper surface. By providing the mark 24M on the upper surface, it is easy to understand that it is in the "mini" state.

[0139] Fig.15 (a)~ Fig.15 (c) is a schematic perspective view illustrating a part of the floor device according to the first embodiment.

[0140] like Fig.15 As shown in (a), in the first bottom plate 10, a contactable portion 10X is provided at a portion where the first portion 11 and the second portion 12 face each other. In the contactable portion 10X, for example, the side surface of the first portion 11 and the side surface of the second portion 12 are in contact.

[0141] like Fig.15 As shown in (b), the first portion 11 includes a first side surface 11s. The second portion 12 includes a second side surface 12s. The first side surface 11s intersects with the first direction (X-axis direction). For example, at least a portion of the first side surface 11s extends in the Y-axis direction. The second side surface 12s intersects with the first direction (X-axis direction). For example, at least a portion of the second side surface 12s extends in the Y-axis direction.

[0142] like Fig.15As shown in (c), in the first state ST1, at least a portion of the second side surface 12s is in contact with the first side surface 11s.

[0143] For example, Fig.15 (b) and Fig.15 As shown in (c), the second part 12 is capable of rotating. Fig.15 As shown in (c), in one state (first state ST1), at least a portion of the second side surface 12s touches the first side surface 11s. Thus, the second portion 12 can be prevented from excessively rotating. Thus, for example, in the first state ST1, the fourth surface 12d of the second portion 12 is substantially parallel to the second surface 11b of the first portion 11. Reverse tilting can be prevented.

[0144] When the second portion 12 is not folded and the first bottom plate 10 (eg, the back bottom plate) is flat (refer to Figure 4 (a)), the load applied to the second portion 12 is applied to, for example, the frame 70F (for example, the second frame portion 70F). Figure 4 In the state illustrated in (a), the second portion 12 is supported by the frame 70F (eg, the second frame portion 70F).

[0145] When the second portion 12 is not folded and the first bottom plate 10 (e.g., the back bottom plate) is in the back-raising state, the load applied to the second portion 12 is applied to the first portion 11 (see FIG. 1 ) through the contact between the first side surface 11s and the second side surface 12s. Fig.15 (c)) The load applied to the second portion 12 may also be applied to the fixing member 15.

[0146] Fig.16 (a) and Fig.16 (b) is a schematic side view illustrating a part of the floor device of the first embodiment.

[0147] These figures illustrate a state of the second base plate 20 (e.g., foot base plate). In one example, the second base plate 20 includes a knee joint base plate 20A and a foot base plate 20B. In this example, the second base plate 20 includes a waist base plate 20C and a foot side bending base plate 20D (lower side bending base plate). There is a knee joint base plate 20A between the waist base plate 20C and the foot base plate 20B. There is a foot side bending base plate 20D between the knee joint base plate 20A and the foot base plate 20B. The angles of these base plates change with each other. The third part 23 and the fourth part 24 are included in the foot base plate 20B.

[0148] Fig.16 The state shown in (a) is the leg-lifting state. In this state, the third portion 23 and the fourth portion 24 are separated from the frame 70F. In this state, the load applied to the fourth portion 24 is applied to the third portion 23 (see FIG. 20 ) via the insertion member 20X. Fig.16 (b))).

[0149] Fig.17 It is a schematic side view illustrating a part of the floor device according to the first embodiment.

[0150] Fig.17 One state of the second bottom plate 20 (e.g., the foot bottom plate) is illustrated. Fig.17 The state shown is a knee-lift state, and at least a portion of the foot (fourth portion 24) is in contact with the frame 70F. In this state, the load applied to the fourth portion 24 is applied to the frame 70F, for example.

[0151] Fig.18 It is a schematic side view illustrating a part of the floor device according to the first embodiment.

[0152] Fig.18 One state of the second bottom plate 20 (e.g., the foot bottom plate) is illustrated. Fig.18 In the state shown, the second bottom plate 20 is flat. In this state, the load applied to the fourth portion 24 is applied to, for example, the frame 70F (for example, the fourth frame portion 70Fd).

[0153] Fig.19 It is a schematic perspective view illustrating a part of the floor device according to the first embodiment.

[0154] The base plate device 170 of the embodiment may also include Fig.19 The illustrated extension member 35. For example, the ends 35a and 35b of the extension member 35 are connected to two parts of the frame 70F. A part of the mattress is placed on the extension member 35. By providing the extension member 35, the bottom plate device 170 can be further extended.

[0155] For example, a recess (or hole) into which the ends 35a and 35b of the extension member 35 are inserted is provided on the back surface of at least one of the first bottom plate 10 and the second bottom plate 20. The extension member 35 is fixed by inserting the ends 35a and 35b into the recess (or hole).

[0156] Fig. 20 (a) and Fig. 20 (b) is a schematic diagram illustrating a part of the floor device according to the first embodiment.

[0157] like Fig. 20 As shown in (a), for example, a wiring fixing portion 10P may be provided on the back side of the first base plate 10. Fig. 20As shown in (b), the wiring fixing part 10P includes a recess 10PD. Various wirings (power cables or sensor signal lines, etc.) can be fixed in the recess 10PD. It is also possible to provide a recess on the back of the second bottom plate 20 to fix various wirings and parts.

[0158] Various concavo-convex shapes may be provided on the back surface of the first base plate 10. Sensors for detecting biological information of the user of the bed 70B may be provided. For example, wiring for the sensor may be fixed to various concavo-convex shapes provided on the back surface of the first base plate 10.

[0160] like Fig.21 As shown, for example, a fixing member 10J may be provided on the back surface of the first base plate 10. The fixing member 10J fixes the relative position of the first base plate 10 and the frame 70F. The fixing member 10J is made of metal, for example.

[0161] Fig. 22 It is a schematic diagram illustrating a part of the floor device according to the first embodiment.

[0162] like Fig. 22 As shown, for example, a hole 10H may be provided in the first base plate 10. For example, a fixing component (e.g., a fastening component) is fixed to the frame 70F through the hole 10H. Thus, the first base plate 10 is fixed to the frame 70F. The first base plate 10 is placed on the frame 70F, and the operation of inserting and fixing the fixing component (e.g., a fastening component) into the hole 10H can be performed from the top. The operation becomes easy. The fixing component (e.g., a fastening component) includes, for example, a screw component and a rivet.
