DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The embodiments and modifications described below are merely examples of the present disclosure, and the present disclosure is not limited to the following embodiments and modifications. Various modifications other than the following embodiments and modifications are possible according to the design, etc., as long as they do not deviate from the technical idea of ​​the present disclosure.

[0011] (Embodiment) Hereinafter, the bathtub stand 1 according to this embodiment will be described with reference to Figs. 1 to 7.

[0012] (1) Overview The bathtub stand 1 of this embodiment is, for example, a bathroom chair.

[0013] In this embodiment, the front-to-rear, left-to-right, and up-to-down directions are defined for the bathtub stand 1, as shown in Figure 1. For example, the short side direction of the bathtub stand 1 is defined as the front-to-rear direction, the long side direction as the left-to-right direction, and the direction perpendicular to both the front-to-rear and left-to-right directions as the up-to-down direction. Figure 1 shows arrows representing these directions (up, down, left, right, front, back), but these arrows are merely shown to aid in the explanation and have no substance. Furthermore, the above-mentioned directional definitions are not intended to limit the manner in which the bathtub stand 1 of this embodiment can be used.

[0014] As shown in Figures 1 and 2, the bathtub stand 1 comprises a plurality of legs 10 (four in the illustrated example) and a base portion 20 supported by the plurality of legs 10. Each of the plurality of legs 10 is formed in a columnar shape including a hollow portion 100 (see Figure 3) along the vertical direction. Each of the plurality of legs 10 has a first opening 111 on the upper side surface of the leg 10 that communicates with the hollow portion 100, and a second opening 125 on the bottom surface that communicates with the hollow portion 100 (see Figure 3). Here, "upper portion of leg 10" refers to the portion of leg 10 close to base portion 20 in the vertical direction.

[0015] According to this configuration, bathtub stand 1 has a first opening 111 on the upper side surface of leg 10 that communicates with hollow portion 100, and a second opening 125 on the bottom surface that communicates with hollow portion 100. Therefore, when bathtub stand 1 is lowered into the bathtub, water easily enters hollow portion 100 through second opening 125, and air inside hollow portion 100 easily escapes through first opening 111. As a result, bathtub stand 1 can be easily lowered into the bathtub.

[0016] (2) Composition Here, the configuration of the bathtub stand 1 of this embodiment will be described in detail.

[0017] 1 and 2, the bathtub stand 1 comprises a plurality of (four in the illustrated example) leg portions 10, a base portion 20 supported by the plurality of leg portions 10, a plurality of (four in the illustrated example) leg rubber portions 30, and a plurality of (four in the illustrated example) adjustment members 40. The plurality of leg portions 10 are in one-to-one correspondence with the plurality of leg rubber portions 30. Furthermore, the plurality of leg portions 10 are in one-to-one correspondence with the plurality of adjustment members 40.

[0018] Each of the multiple legs 10 is formed in a columnar shape including a hollow portion 100 along the vertical direction. Each of the multiple legs 10 has a first opening 111 communicating with the hollow portion 100 on the upper side surface, and a second opening 125 communicating with the hollow portion 100 on the bottom surface.

[0019] Each of the plurality of legs 10 includes a support leg 11 that supports the base 20, and an adjustable leg 12 that is configured to allow the height of the base 20 to be adjusted.

[0020] The support leg 11 has a first hollow portion 101 which is a part of the hollow portion 100, and the above-mentioned first opening 111 which communicates with the first hollow portion 101. The first opening 111 connects the external space (the space outside the bathtub stand 1) to the first hollow portion 101 of the hollow portion 100. The support leg 11 has a pair of fixing through holes 112 facing each other in a direction intersecting the vertical direction (for example, left and right rear) below the support leg 11. The appearance of the support leg 11 is, for example, a cylindrical or truncated cone shape. In this embodiment, the appearance of the support leg 11 is a truncated cone shape. That is, in a cross section of the support leg 11 in a direction perpendicular to the vertical direction, the outer periphery 11a of the support leg 11 is circular (see FIG. 4). Also, the inner circumference 11b forming the first hollow portion 101 of the support leg 11 is formed so that the cross section of the support leg 11 in a direction perpendicular to the vertical direction is D-shaped (see FIG. 4). That is, the support leg 11 is formed so that the outer circumference 11a of the support leg 11 is circular and the inner circumference 11b of the support leg 11 is D-shaped in the cross section of the support leg 11 in a direction perpendicular to the vertical direction. In other words, the support leg 11 is formed so that a part of the inner circumference 11b of the support leg 11 is linear and the remaining part is arc-shaped in the cross section of the support leg 11 in a direction perpendicular to the vertical direction.

[0021] The adjustable leg 12 has a second hollow portion 102 which is a part of the hollow portion 100, and the above-mentioned second opening 125 which communicates with the second hollow portion 102. In a cross section of the support leg 11 in a direction perpendicular to the vertical direction, the outer periphery 12a of the adjustable leg 12 is formed to be D-shaped (see FIG. 5). In other words, in a cross section of the adjustment leg 12 in a direction perpendicular to the vertical direction, the adjustment leg 12 is formed so that a part of the outer periphery 12a of the adjustment leg 12 is linear and the remaining part is arc-shaped. The adjustment leg 12 is inserted into the first hollow portion 101 of the support leg 11. More specifically, the tip of the adjustment leg 12 is inserted into the first hollow portion 101 of the support leg 11. In addition, the adjustment leg 12 has an upper opening 126 at the upper end which communicates with the second hollow portion 102 (see FIG. 3). Since the adjustable leg portion 12 has an upper opening 126 , the first hollow portion 102 and the first hollow portion 101 are connected to each other, and the hollow portion 100 is formed.

[0022] Each of the multiple legs 10 has a pair of leg rubber fixing through holes 122 for fixing a corresponding one of the multiple leg rubber parts 30 (see FIG. 7). Specifically, each adjustable leg part 12 of the multiple legs 10 has a pair of leg rubber fixing through holes 122 below the adjustable leg part 12.

[0023] The adjustable leg 12 is configured to be able to adjust the height of the base 20. Specifically, as shown in FIG. 3, the adjustable leg 12 has a plurality of (five in the illustrated example) pairs of adjustment through holes 121 in the up-down direction. For example, when the leg 10 is viewed from the left-right direction, the support leg 11 and the adjustable leg 12 are fixed using the adjustment member 40 at a position where the pair of fixing through holes 112 of the support leg 11 overlaps with the pair of adjustment through holes 121 of one of the plurality of pairs of adjustment through holes 121. A plurality of pairs of adjustment through holes 121 are provided along the up-down direction of the adjustable leg 12. Therefore, by selecting one of the plurality of pairs, it is possible to adjust the length by which the adjustable leg 12 protrudes from the support leg 11, that is, to adjust the height of the base 20.

[0024] The multiple leg rubber parts 30 correspond one-to-one to the multiple leg parts 10. The multiple leg rubber parts 30 are provided at the lower ends of the corresponding leg rubber parts 30 among the multiple leg rubber parts 30. The multiple leg rubber parts 30 have third openings 301 that communicate with the hollow part 100 via the second openings 125 of the corresponding leg part 10 among the multiple leg parts 10 (see FIG. 3). Specifically, the multiple leg rubber parts 30 are provided at the lower ends of the adjustable leg parts 12 of the corresponding leg rubber parts 30 among the multiple leg rubber parts 30 (see FIG. 3).

[0025] Each of the multiple leg rubber parts 30 has a connection member 31 and a rubber part main body 32 (see Figures 6 and 7). The connection member 31 is a member for connecting to a corresponding leg part 10 among the multiple leg parts 10. A third opening 301 is provided on the bottom surface 32a of the rubber part main body 32 (see Figure 7). Furthermore, the bottom surface 32a of the rubber part main body 32 is provided with multiple (e.g., three) suction cups 32b (see Figure 7) that come into contact with the bottom surface, floor, etc. of the bathtub. By attaching each of the multiple suction cups 32b to the bottom surface, floor, etc. of the bathtub, the bathtub stand 1 can be fixed to the bottom surface and floor of the bathtub.

[0026] 6, the connection member 31 has a connection main body 311 and a pair of fixing protrusions 312 facing each other. The connection main body 311 is provided on the upper part of the rubber main body 32. The connection main body 311 has a fourth opening 313 communicating with the third opening 301. When the leg rubber part 30 is attached to the adjustable leg part 12, the fourth opening 313 communicates with the second opening 125. The pair of fixing protrusions 312 protrude upward from the connection main body 311 and face each other.

[0027] Each of the multiple leg rubber parts 30 is fixed at the lower end of the leg rubber part 30 by fitting the tips of a pair of fixing protrusions 312 of the connection member 31 of the leg rubber part 30 into a pair of leg rubber fixing through holes 122 of the corresponding leg part 10 (adjustable leg part 12) among the multiple leg parts 10. More specifically, the pair of fixing protrusions 312 have protrusions 314 at their tips that protrude in the opposite direction to the opposing fixing protrusions 312 (see FIG. 7). The protrusions 314 are configured to be exposed from the leg rubber fixing through holes 122 when the tips of the fixing protrusions 312 having the protrusions 314 are fitted into the corresponding leg rubber fixing through holes 122 among the pair of leg rubber fixing through holes 122.

[0028] Each of the plurality of adjustment members 40 is a member used when adjusting the length by which the adjustable leg portion 12 protrudes from the support leg portion 11, i.e., when fixing the adjustable leg portion 12 to the support leg portion 11 when adjusting the height of the base portion 20. Each of the adjustment members 40 has a first member 41 and a second member 42, as shown in FIG.

[0029] The first member 41 is a ring-shaped member and is provided at the lower end of the support leg 11. The first member 41 has through holes facing each other. The second member 42 is, for example, a pin. For example, when the leg 10 is viewed from the left-right direction, the second member 42 is inserted when a pair of adjustment through holes 121 of one of a plurality of pairs of the pair of fixing through holes 112 of the support leg 11 and the pair of adjustment through holes 121 of the pair of through holes provided in the first member 41 overlap with each other. Thereafter, the second member 42 is inserted into the support leg 11 and the adjustment leg 12, so that the adjustment leg 12 is fixed to the support leg 11. The second member 42 may be a screw. When the second member 42 is a screw, the adjustment leg 12 is fixed to the support leg 11 by tightening the first member 41 to the support leg 11 and the adjustment leg 12 using the second member 42.

[0030] The base 20 has a polygonal shape. In this embodiment, the base 20 has a rectangular shape. The base 20 has a main body 21 supported by a plurality of legs 10, and a seat 22 fitted into the main body 21. The main body 21 and the seat 22 have a polygonal shape (here, a rectangular shape).

[0031] The base portion 20 has a drainage hole 221 in the center. The drainage hole 221 is a through hole that penetrates the center of the main body portion 21 and the center of the seat portion 22.

[0032] The seat portion 22 is formed in a plate shape. The seat portion 22 has at least one first protruding portion 222 protruding downward on the outer periphery of the seat portion 22. In this embodiment, the seat portion 22 has the first protruding portion 222 on each of two long sides in the longitudinal direction (left and right direction) and two short sides in the short direction (front and back direction) of the outer periphery of the seat portion 22, that is, on each of the four sides forming the seat portion 22. In other words, in this embodiment, the seat portion 22 has four first protruding portions 222 on the outer periphery of the seat portion 22. The lower end of the first protruding portion 222 is formed in a curved shape. Specifically, the lower end of the first protruding portion 222 is formed in a curved shape along the side (long side or short side) of the seat portion 22 on which the first protruding portion 222 is provided.

[0033] In this embodiment, the first protrusion 222 is provided on a part of the outer periphery of the seat portion 22. Note that the first protrusion 222 may be provided on the entire outer periphery. In other words, it is sufficient that the first protrusion 222 is provided on at least a part of the outer periphery.

[0034] The main body 21 has a second protrusion 212 on the inside of a side surface of the main body 21. When the first protrusion 222 is viewed along a direction from the first protrusion 222 toward the center of the base (the longitudinal direction and lateral direction of the base 20), the second protrusion 212 protrudes downward, and at least a part of the second protrusion 212 overlaps with the first protrusion 222. In this embodiment, the main body 21 has the second protrusion 212 on each of two long sides in the longitudinal direction (left-right direction) and two short sides in the lateral direction (front-rear direction), i.e., on each of the four sides that form the main body 21.

[0035] In this embodiment, the second protrusion 212 is provided on the entire long side or the entire short side of the main body 21. The second protrusion 212 may be provided on a part of the long side or a part of the short side of the main body 21. That is, when the first protrusion 222 is viewed along the direction from the first protrusion 222 toward the center of the base (the long side direction or the short side direction of the base 20), it is sufficient that at least a part of the second protrusion 212 overlaps with the first protrusion 222.

[0036] As shown in FIG. 1, the main body 21 has a plurality of (two in the illustrated example) main body side openings 211 on a side surface 21a along the short side direction (front-rear direction) of the main body 21. The plurality of main body side openings 211 correspond one-to-one to the plurality of first openings 111. The plurality of main body side openings 211 communicate with corresponding first openings 111 among the plurality of first openings 111 (see FIG. 3). That is, the main body 21 of the stand 20 and the plurality of support legs 11 are integrally molded. Each of the plurality of first openings 111 connects the external space (space outside the bathtub stand 1) to the hollow portion 100 via the corresponding main body side openings 211 among the plurality of main body side openings 211.

[0037] (3) Effects As described above, the bathtub stand 1 comprises a plurality of (e.g., four) legs 10 and a base portion 20 supported by the plurality of legs 10. Each of the plurality of legs 10 is formed in a columnar shape including a hollow portion 100 along the up-down direction. Each of the plurality of legs 10 has a first opening 111 on the upper side surface of the leg 10 that communicates with the hollow portion 100, and a second opening 125 on the bottom surface that communicates with the hollow portion 100.

[0038] According to this configuration, bathtub stand 1 has a first opening 111 on the upper side surface of leg 10 that communicates with hollow portion 100, and a second opening 125 on the bottom surface that communicates with hollow portion 100. Therefore, when bathtub stand 1 is lowered into the bathtub, water easily enters hollow portion 100 through second opening 125, and air inside hollow portion 100 easily escapes through first opening 111. As a result, bathtub stand 1 can be easily lowered into the bathtub.

[0039] (4) Variations Modifications will be described below. The modifications described below can be applied in appropriate combination with the above embodiment.

[0040] (4.1) Variation 1 The base portion 20 may be formed so that the center of the base portion 20 is recessed in both the left-right direction and the front-rear direction.

[0041] This configuration improves drainage, reducing the occurrence of mold on the bathtub stand 1, particularly on the stand portion 20. Furthermore, because water drains well, the bathtub stand 1 provides a more comfortable feel on the buttocks when the user sits on it.

[0042] (4.2) Variation 2 Each of the plurality of first openings 111 is configured to connect the external space to the hollow portion 100 via a corresponding one of the plurality of main body portion side openings 211. However, the present invention is not limited to this configuration.

[0043] Each of the plurality of first openings 111 may be configured to connect the external space to the hollow portion 100 without any other component therebetween.

[0044] In this case, each of the multiple first openings 111 does not need to be integrally molded with the main body 21 of the base 20. In other words, each of the multiple first openings 111 may be provided separately from the main body 21 of the base 20.

[0045] (4.3) Variation 3 The lower end of the first protruding portion 222 is configured to be curved along the side on which the first protruding portion 222 is provided, but is not limited to this configuration.

[0046] The lower end of the first protruding portion 222 may be formed in a straight line shape along the side on which the first protruding portion 222 is provided. In other words, the first protruding portion 222 only needs to serve as a marker for the presence of the second protruding portion 212. Forming the lower end of the first protruding portion 222 in a curved shape provides better design than a straight line shape.

[0047] (4.4) Variation 4 The bathtub stand 1 is configured to be height adjustable, but is not limited to this configuration. The bathtub stand 1 may also be configured to have a fixed height. That is, each of the multiple legs 10 may have a first opening 111 that communicates with the hollow portion 100 on the upper side surface of the leg 10, and a second opening 125 that communicates with the hollow portion 100 on the bottom surface.

[0048] (4.5) Variation 5 The base portion 20 of the bathtub stand 1 is rectangular (quadrilateral) as an example of a polygonal shape, but the base portion 20 is not limited to a rectangular shape. The base portion 20 may be triangular or pentagonal. Or, it may be a shape with hexagons or more.

[0049] Furthermore, the base 20 may be circular or elliptical. When the base 20 is circular or elliptical, a first protrusion 222 is provided on a part of the outer edge (curve) of the seat 22 of the base 20.

[0050] (4.6) Variation 6 The leg 10 of the bathtub stand 1 is configured to have a first opening 111 on the upper side surface of the leg 10, but is not limited to this configuration.

[0051] The first opening 111 may be provided on the side surface of the leg 10. Preferably, the first opening 111 may be provided on the side surface at a position that is ½ or more of the length of the leg 10 from the end of the leg 10 (the end surface where the leg rubber portion 30 is provided). More preferably, the first opening 111 may be provided on the side surface at a position that is ¾ or more of the length of the leg 10 from the end of the leg 10 (the end surface where the leg rubber portion 30 is provided).

[0052] When the length of leg 10 is adjustable, first opening 111 may be provided on the side surface at a position that is ½ or more of the length of leg 10 from the end of leg 10 (the end where leg rubber part 30 is provided) when leg 10 is at its shortest. More preferably, first opening 111 may be provided on the side surface at a position that is ¾ or more of the length of leg 10 from the end of leg 10 (the end where leg rubber part 30 is provided) when leg 10 is at its shortest.

[0053] (summary) As described above, the bathtub stand (1) of the first embodiment comprises a plurality of legs (10) and a base portion (20) supported by the plurality of legs (10). Each of the plurality of legs (10) is formed in a columnar shape including a hollow portion (100) along the vertical direction. Each of the plurality of legs (10) has a first opening (111) on the upper side surface that communicates with the hollow portion (100), and a second opening (125) on the bottom surface that communicates with the hollow portion (100).

[0054] With this configuration, when the bathtub stand (1) is lowered into the bathtub, water can easily enter the hollow portion (100) through the second opening (125), and air can easily be expelled from the hollow portion (100) through the first opening (111). As a result, the bathtub stand (1) can be easily lowered into the bathtub.

[0055] The bathtub stand (1) of the second embodiment is the same as that of the first embodiment, but further includes a plurality of leg rubber parts (30) that correspond one-to-one to the plurality of leg parts (10). The plurality of leg rubber parts (30) are provided at the lower ends of corresponding ones of the plurality of leg parts (10). The plurality of leg rubber parts (30) have third openings (301) that communicate with the hollow part (100) via the second openings (125) of the corresponding ones of the plurality of leg parts (10).

[0056] With this configuration, the bathtub stand (1) can be easily lowered into the bathtub.

[0057] In the bathtub stand (1) of the third embodiment, in the second embodiment, each of the multiple leg rubber parts (30) has a connection member (31) for connecting to a corresponding leg part (10) among the multiple leg parts (10). The connection member (31) has a connection main body part (311) and a pair of fixing protrusions (312) facing each other. The connection main body part (311) has a fourth opening part (313) that communicates with the third opening part (301). The pair of fixing protrusions (312) protrude upward from the connection main body part (311). The multiple leg parts (10) have a pair of leg rubber fixing through holes (122) for fixing the corresponding leg rubber part (30) among the multiple leg rubber parts (30). Each of the multiple leg rubber portions (30) is fixed at the lower end of the leg portion (10) by fitting the tips of a pair of fixing protrusions (312) of the connecting member (31) of the leg rubber portion (30) into a pair of leg rubber fixing through holes (122) of a corresponding leg portion (10) among the multiple leg portions (10).

[0058] According to this configuration, the leg rubber parts (30) can be fixed to the leg parts (10) more reliably.

[0059] In the bathtub stand (1) of the fourth embodiment, in the third embodiment, the pair of fixing protrusions (312) have, at their tips, protruding portions (314) that protrude in the opposite direction to the opposing fixing protrusions (312). The protrusions (314) are configured to be exposed from the leg rubber fixing through holes (122) when their tips are fitted into the corresponding one of the pair of leg rubber fixing through holes (122).

[0060] According to this configuration, the protrusions (314) of the leg rubber parts (30) are exposed from the leg parts (10), so that the leg rubber parts (30) can be easily removed.

[0061] In the bathtub stand (1) of the fifth aspect, in any one of the first to fourth aspects, each of the multiple legs (10) includes a support leg (11) that supports the base part (20) and an adjustable leg (12) that is configured to allow the height of the base part (20) to be adjusted. The support leg (11) has a first hollow part (101) that is a part of the hollow part (100) and a first opening part (111) that communicates with the first hollow part (101). The support leg (11) is formed so that the inner circumference of the support leg (11) is D-shaped in a cross section of the support leg (11) in a direction perpendicular to the up-down direction. The adjustable leg (12) has a second hollow part (102) that is a part of the hollow part (100) and a second opening part (125) that communicates with the second hollow part (102). The adjustable leg portion (12) is formed so that the outer periphery of the adjustable leg portion (12) is D-shaped in a cross-section of the adjustable leg portion (12) in a direction perpendicular to the vertical direction, and is inserted into the first hollow portion (101) of the support leg portion (11).

[0062] According to this configuration, since the inner circumference of the support leg portion (11) is D-shaped and the outer circumference of the adjustable leg portion (12) is D-shaped, it is possible to prevent the adjustable leg portion (12) from rotating unnecessarily after the adjustable leg portion (12) is inserted into the first hollow portion (101) of the support leg portion (11). For example, after the adjustable leg portion (12) is inserted into the first hollow portion (101) of the support leg portion (11), when the adjustable leg portion (12) is fixed to the support leg portion (11), the adjustable leg portion (12) can be easily fixed because it does not rotate unnecessarily.

[0063] In the bathtub stand (1) of the sixth aspect, in any one of the first to fifth aspects, the stand portion (20) has a drain hole (221) in the center.

[0064] This configuration improves drainage.

[0065] In the bathtub stand (1) of the seventh aspect, in the sixth aspect, the base portion (20) is formed so that the center portion of the base portion (20) is recessed in both the left-right direction and the front-rear direction.

[0066] This configuration allows for better drainage, which in turn reduces the occurrence of mold on the bathtub stand (1), particularly the stand portion (20), and improves the feel on the user's buttocks when sitting on the bathtub stand (1).

[0067] In the bathtub stand (1) of the eighth aspect, in any of the first to seventh aspects, the base portion (20) has a main body portion (21) and a seat portion (22) fitted into the main body portion (21). The main body portion (21) is supported by a plurality of legs (10). The seat portion (22) has at least one first protrusion (222) that protrudes downward on the outer periphery of the seat portion (22). The main body portion (21) has a second protrusion (212). When the first protrusion (222) is viewed along a direction from the first protrusion (222) toward the center of the base portion (20), the second protrusion (212) protrudes downward and at least partially overlaps with the first protrusion (222).

[0068] According to this configuration, the first protrusion (222) serves as a marker indicating the position of the second protrusion (212). For example, when the second protrusion (212) is used as a handle, the position of the handle can be ascertained simply by checking the position of the first protrusion (222).

[0069] In the bathtub stand (1) of the ninth aspect, in the eighth aspect, the lower end of the first protrusion (222) is formed in a curved shape.

[0070] This configuration improves the design. [Explanation of symbols]
