Description

[Technical field]

[0001] The present invention relates to a self-sinking bathtub stand having a base and three or more rod-shaped legs, and in particular to a self-sinking bathtub stand that is equipped with a ballast portion that is positioned eccentrically outside the outer peripheral surface of one or more of the legs. [Background technology]

[0002] Generally, bathtubs are deep, and users cannot fully immerse themselves in the water unless they lower their hips (buttocks) to the bottom of the bathtub, so if the user is elderly or disabled, they may be unable to step over the side wall to enter the bathtub or be unable to stand up from a lowered position. For this reason, bathtubs have been made shallower than before, and bathtub stools for seats and steps that can be sunk into the water have been developed so that elderly and disabled people do not have to lower their hips to the bottom of the bathtub.

[0003] In addition, since the body shapes of bathtub stand users vary greatly, in recent years there has been a trend toward bathtub stands whose legs can be extended or contracted so that the height of the base (seat) can be freely adjusted, rather than one-piece molded plastic chairs whose seat height cannot be adjusted.

[0004] However, even in bathtub stands with legs, because they are made lighter by using a lot of resin materials for ease of portability, there is a problem that if the specific gravity of the bathtub stand is lighter than that of water, it cannot be stably lowered to the bottom of the bathtub. For this reason, bathtub stools have been developed that prevent slipping on the bottom of the bathtub by providing suction cups at the bottom ends of the legs that support the seat, allowing the bathtub stool to be stably lowered into the water, such as the bathtub stool described in Utility Model Registration No. 3061477 (Patent Document 1).

[0005] However, in recent years, bathtubs often have small projections and recesses on the bottom to prevent users from slipping in the bathtub, and wooden bathtubs such as those made of cypress are also used. For this reason, the bath stool described in Patent Document 1 has the problem that the suction cups on the legs do not stick to the bottom of the bathtub in such bathtubs, making it impossible to stably place it in the water.

[0006] In addition, bathtub stands have been developed in which the base supported by the legs is insert molded using a steel plate with a density greater than that of water, allowing the stand to be stably submerged in water by its own weight, such as the bathtub stand described in JP 2018-15419 A (Patent Document 2).

[0007] However, the bathtub stand described in Patent Document 2 had the problem that the structure and manufacturing process of the base part in which the steel plate is insert-molded was complicated and large-scale, resulting in high costs. Also, in the bathtub stand in Patent Document 2, the base part, which is the sinking means, is a dedicated product with no versatility, so not only could it not be reused from other bathtub stands or repurposed for other bathtub stands, but also there was the problem that if the base part was damaged for some reason, the entire bathtub stand would essentially have to be replaced.

[0008] [Patent Document 1] Utility Model Registration No. 3061477 [Patent Document 2] JP2018-15419A Summary of the Invention [Problem to be solved by the invention]

[0009] Therefore, the object of the present invention is to provide a bathtub stand with rod-shaped legs that has a simple structure, can be easily submerged in a bathtub filled with hot water, and can be stably installed on the bottom of the bathtub, and further has a submersion means that can be applied and expanded to other bathtub stands. [Means for solving the problem]

[0010] After extensive research into the structure of the legs and base that make up the bathtub stand, the inventors discovered that the above-mentioned problems could be solved by attaching an external sinking means consisting of a weight or the like to a specific position on the leg, and thus completed the present invention.

[0011] That is, according to the present invention, there is provided a bathtub stand comprising three or more rod-shaped legs, a base supported by the legs, and a ballast part having a density greater than that of water and attached to the legs, the ballast part being eccentrically disposed outside the outer peripheral surface of the legs in one or more legs. It is also preferable that the ballast part is disposed within a base projection area surrounded by the outermost line segments connecting adjacent legs in a plan view.

[0012] In the present invention, the ballast portion functions as a sinking means for sinking the bathtub stand in a bathtub filled with hot water. The ballast portion only needs to be positioned eccentrically outward from the outer peripheral surface of one or more legs of the bathtub stand, so it can be externally attached or retrofitted to the outside of the legs of any bathtub stand that has legs. In addition, when the ballast portion is positioned within the projection area of ​​the stand, the ballast portion is prevented from interfering with the bathtub sidewall, so that the bathtub stand and its legs can be installed in contact with or close to the bathtub sidewall.

[0013] In the present invention, in order to make it easy for the bathtub stand to sink appropriately in hot water, when the ballast part is attached to the legs, it is preferable to adjust the weight of the ballast part so that the apparent specific gravity of the entire bathtub stand is 1.2 or more, and in order to avoid compromising the ease of carrying the bathtub stand, it is preferable to adjust the weight of the ballast part so that the apparent specific gravity of the entire bathtub stand is 2.0 or less.

[0014] Ballast parts do not need to be attached to all legs, but may be attached to one or more legs. In particular, when the ballast parts are arranged eccentrically on the outside of the legs within the projection area of ​​the platform, a moment acts on the legs to suppress the movement of the legs on which the ballast parts are not arranged to float up, so the bathtub stand can be stabilized by arranging the minimum number of ballast parts necessary.

[0015] As described above, the bathtub stand of the present invention has an extremely simple structure, and can be easily submerged in a bathtub filled with hot water and stably installed on the bottom of the bathtub.Furthermore, the ballast portion, which serves as the submersion means, can be applied and deployed to other bathtub stands.

[0016] In the present invention, the sole portion may be detachably attached to the lower end of the leg, and the ballast portion may be fixed to the sole portion so as to be eccentrically disposed outward from the outer circumferential surface of the leg. It is also preferable that the sole portion has a substantially cylindrical cap portion that is fitted onto the lower end of the leg by being inserted externally or internally, and that the leg portion is further provided with an engagement hole and a side wall of the cap portion is provided with an engagement hook that biases the cap portion to engage with the engagement hole.

[0017] Since a sole is usually attached to the lower end of the legs of the bathtub stand for the purpose of preventing slipping, etc., if the sole is used as a means for attaching the ballast, the bathtub stand can be constructed with an extremely simple structure. In particular, if a roughly cylindrical cap is provided on the sole, the sole and the ballast supported by the sole can be attached with a single touch by inserting the cap externally or internally onto the lower end of the leg and engaging the engaging hook on the side wall of the cap with the engaging hole in the leg.

[0018] In addition, since the sole part itself is replaceable, it can be applied and deployed to other bathtub stools as long as they have legs. Furthermore, since the sole part is attached to the lower end of the leg, the ballast part is also placed in the lower region of the leg at the same time, and as a result, the center of gravity of the bathtub stool moves downward, making it less likely to tip over.

[0019] In addition, in the present invention, the sole part may be divided into a first bottom part disposed in the lower region of the leg part and a second bottom part disposed in the lower region of the ballast part, and the second bottom part may be disposed at a higher position than the first bottom part so as to be separated from the ground surface when the sole part is placed on the ground. In this case, a moment acts on the leg to which the ballast part is attached using the sole part so as to suppress the lifting of the other leg facing the leg, so that the bathtub stand can be stabilized with the minimum number of ballast parts required.

[0020] In addition, in a form in which the ballast portion is attached to the legs using the sole portion, if the legs are made of hollow pipe members, it is preferable to provide the bathtub stand with a through hole communicating with the inside of the legs and to provide a drainage hole at the bottom of the cap portion in order to allow water to flow into the inside of the legs to prevent buoyancy caused by residual air, and to smoothly drain stagnant water that has accumulated on the seat of the bathtub stand and water that has entered the legs from the sole portion.

[0021] The sole portion is attached to prevent the legs from slipping or being scratched in the bathtub, and is therefore preferably made of a soft resin material having a certain degree of elasticity, such as an elastomer such as synthetic rubber. The sole portion may also be made of a hard resin material, metal material, or a composite material thereof, as a core material in order to support the ballast portion. On the other hand, since the ballast portion functions as a means for lowering the bathtub platform, it is preferably made of a metal material such as iron or stainless steel, which is easy to obtain and has a higher specific gravity than water, and the ballast portion is preferably covered with a resin material to prevent the metal material from rusting.

[0022] Furthermore, the bathtub stand of the present invention can basically utilize the configuration of the bathtub stand of the prior art, except for the ballast part being placed at a specific position on the leg using the sole part, as described above, and can inherit the benefits of the bathtub stand. Therefore, in order to enjoy the benefits of the bathtub stand of the prior art, it is preferable that the bathtub stand of the present invention is provided with a cushion part that can be attached and detached on the top surface of the stand to protect the user's body, and that the length of each leg can be made extendable so that the height of the stand (seat part) can be freely adjusted. Effect of the Invention

[0023] According to the present invention, there is provided a bathtub stand comprising three or more rod-shaped legs, a base supported by the legs, and a ballast portion having a density greater than that of water and attached to the legs, wherein the ballast portion is positioned eccentrically outwardly from the outer peripheral surface of the legs in one or more of the legs, and further, it is preferable that the ballast portion is positioned within a base projection area surrounded by the outermost line segments connecting adjacent legs in a plan view.

[0024] The bathtub stand of the present invention has an extremely simple structure because the ballast part attached to the legs functions as the sinking means, and can be easily submerged in a bathtub filled with hot water and stably installed on the bottom of the bathtub. In particular, when the ballast part is located within the projection area of ​​the legs, the ballast part is prevented from interfering with the side wall of the bathtub, so the bathtub stand and its legs can be installed in contact with or close to the side wall of the bathtub. Furthermore, because the ballast part, which is the sinking means, can be attached externally to the outside of the legs or added later, it can be applied and deployed to other bathtub stands as long as they have legs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] Hereinafter, a bathtub stand according to one embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following examples, and various modifications are possible within the scope of the technical concept of the present invention.

[0027] Fig. 1 shows a perspective view of a bathtub stand 1 according to one embodiment of the present invention as viewed from above, and Fig. 2 shows a perspective view of the bathtub stand 1 shown in Fig. 1 as viewed from below. Fig. 3 shows a cross-sectional view of the leg 3 of the bathtub stand 1 shown in Fig. 1 taken along line AA, and Fig. 4 shows a cross-sectional view of the leg 3 of the bathtub stand 1 shown in Fig. 1 taken along line BB. Also, Fig. 5 shows a perspective view showing a fixing member.

[0028] As shown in Figures 1 to 4, the bathtub stand 1 of this embodiment comprises a base 2 having a seat surface to which a cushion 20 is removably attached, and legs 3 attached to the underside of the base 2 and supporting the base 2 from below. A sole 4 to which a cap 7 and a ballast 8 are fixed is removably attached to the lower end of each of the four legs 3 via the cap 7. The legs 3 are made of a corrosion-resistant material such as stainless steel, but the material of the legs 3 is not limited to metal and may be non-metallic.

[0029] The leg 3 is composed of a first leg 30 made of a hollow pipe member and fixed to the base 2, and a second leg 31 made of a hollow pipe member and slidably inserted into the first leg 30. A pair of fixing holes 300 is provided at the lower part of the first leg 30 at the same level, and a plurality of pairs of adjustment holes 310 aligned with the fixing holes 300 are provided in the second leg 31 at the same pitch in the longitudinal direction. Therefore, in this embodiment, if any pair of fixing holes 310 of the second leg 31 is aligned with the pair of fixing holes 300 of the first leg 30, and a pin 90 (FIG. 5) of the fixing member 9 is inserted so as to pass through the pair of fixing holes 300 and the pair of fixing holes 310, the entire leg 3 can be fixed by expanding and contracting to a desired length.

[0030] Fig. 6 shows a perspective view of the sole part 4 having the cap part 7 and the ballast part 8 as viewed from above, and Fig. 7 shows a perspective view of the sole part 4 shown in Fig. 6 as viewed from below. Fig. 8 shows an exploded view of the sole part 4 shown in Figs. 6 and 7 as disassembled into the sole body 5 and the cover body 6 as viewed from above, and Fig. 9 shows an exploded view of the sole part 4 shown in Figs. 6 and 7 as disassembled into the sole body 5 and the cover body 6 as viewed from below.

[0031] As shown in Figs. 6 to 9, the sole part 4 has a substantially triangular rice ball shape in a plan view, and is composed of a sole body 5 made of a relatively soft resin material having a certain elasticity such as natural rubber or synthetic rubber, and a cover body 6 made of a relatively hard resin material such as polypropylene, polyethylene, or ABS (acrylonitrile butadiene styrene) having a substantially similar rice ball shape in a plan view and attached to the sole body 5. An edge part 60 is provided on the periphery of the cover body 6, and a fitting groove 50 is provided horizontally on the upper surface of the sole body 5, and the cover body 6 is detachably attached by fitting the edge part 60 into the fitting groove 50 of the sole body 5. The cover body 6 and the sole body 5 may be integrally molded in a mold, for example, by injection molding the sole body 5 using a mold into which the cover body 6 is inserted.

[0032] The cover body 6 has a substantially cylindrical cap portion 7 and a ballast portion 8 that bulges out like a ridge so as to form one side of the rice ball-shaped cover body 6, and in this embodiment, the cap portion 7 and the ballast portion 8 are integrally molded. However, the cap portion 7 and the ballast portion 8 do not necessarily have to be integrally molded, and may be molded as separate independent parts, or may be molded from different materials. In addition, from the viewpoint of reinforcement, the cap portion 7 and the ballast portion 8, which are independent from each other, may be connected by using a metal plate or the like.

[0033] The cap portion 7 is formed in a substantially cylindrical shape, and two mutually opposing engagement hooks 70 are formed in the side wall of the cap portion 7 by hollowing out the side wall to form a downward U-shaped slit. The cap portion 7 is preferably formed from polypropylene from the viewpoints of providing appropriate bending to the engagement hooks 70 and excellent heat resistance.

[0034] Furthermore, in the side wall of the cap portion 7, two opposing notches 72 are provided by cutting out a U-shape at a position of the side wall aligned with the adjustment hole 310 so as not to interfere with the pin 90 of the fixing member 9 inserted through the lowest adjustment hole 310 of the second leg portion 31. However, if the adjustment hole 310 of the second leg portion 31 does not overlap with the side wall of the cap portion 7, it is not necessary to provide the above-mentioned notches 72.

[0035] An end of the engagement hook 70 is formed with a generally cylindrical projection 71 that projects outward beyond the outer circumferential surfaces of the cap portion 7 and the engagement hook 70. Meanwhile, the second leg portion 31 is provided with two opposing engagement holes 32 that engage with the projections 71 of the two engagement hooks 70, as shown in FIG.

[0036] Therefore, when the cap part 7 is inserted into the second leg part 31, the surface of the protrusion part 71 is initially pressed against the inner peripheral surface of the second leg part 31, bending the engagement hook 70 toward the inside of the cap part 7 so as to be flush with the outer peripheral surface of the cap part 7. When the cap part 7 is further pushed into the second leg part 31, the protrusion part 71 is biased to engage with the engagement hole 32 by the elasticity of the engagement hook 70, so that the protrusion part 71 reaches the engagement hole 32 of the second leg part 31 and engages with the engagement hole 32, and the cap part 7, the cover body 6, and the sole body 5 attached to the cover body 6 are fixed to the leg part 3. In addition, the engagement between the protrusion part 71 and the engagement hole 32 is released by pushing the protrusion part 71 in the engagement hole 32 toward the back side from the outside of the second leg part 31, and the sole part 4 can be easily removed from the leg part 3.

[0037] In this manner, the sole portion 4 is detachably attached to cover the lower end of the leg 3 by inserting and fitting the cap portion 7 into the lower end of the second leg 31 (FIGS. 3 and 4). Although not shown, the sole portion 4 may be attached to the leg 3 by inserting and fitting the cap portion 7 externally onto the lower end of the leg 3.

[0038] The ballast section 8 is composed of a ballast body 80 that functions as a weight, and a ballast cover 81 that covers the ballast body 80. The ballast body 80 is inserted into the ballast cover 81 that bulges out like a ridge, and can be formed using any known material, without any particular limitation, as long as the material has a specific gravity greater than that of water. In this embodiment, the ballast body 80 is preferably formed from a metal material such as iron or stainless steel, since these materials are easy to obtain and process.

[0039] The weight of the ballast section 8 can be adjusted by changing not only the material of the ballast body 80, but also its shape and size. In order to allow the bathtub stand 1 to which the ballast section 8 is attached to be easily and stably installed on the bottom of the bathtub in a bathtub filled with hot water, it is preferable to adjust the weight of the ballast section 8 so that the apparent specific gravity of the entire bathtub stand 1 is 1.2 or more, while in order not to impair the ease of portability of the bathtub stand 1, it is more preferable to adjust the apparent specific gravity of the entire bathtub stand 1 to 2.0 or less. Also, the ballast section 8 does not necessarily need to be attached to all of the legs 3 of the bathtub stand 1, and it is sufficient if it is attached to one or more legs 3.

[0040] The ballast portion 8 is preferably covered with a resin material in order to improve corrosion resistance. In this embodiment, the upper surface and side surfaces of the ballast body 80 are covered with a ballast cover 81 as a part of the cover body 6, and the lower surface of the ballast body 80 is covered with the sole body 5 by attaching the sole body 5 (FIGS. 3 and 9).

[0041] In this embodiment, the ballast part 8 is attached to the lower part of the second leg part 31 using the sole part 4. However, the attachment means of the ballast part 8 is not limited to this, and any known attachment means may be used as long as the ballast part 8 can be fixed eccentrically outward from the outer circumferential surface of the leg part 3. The attachment position of the ballast part 8 does not necessarily have to be the lower part of the leg part 3, and may be the middle part or the upper part of the leg part 3. In other words, the ballast part 8 may be attached to the first leg part 30 or the second leg part 31, and although not shown, the ballast part may be attached to a belt-shaped band, for example, and the band may be wrapped around the leg, so that the ballast part is attached eccentrically at any height of the leg.

[0042] 8 and 9, the sole body 5, which includes the cap portion 7 and the ballast portion 8 and is attached to the cover body 6, has a generally triangular rice ball shape in plan view. The sole body 5 is provided with a water drainage hole 51 that communicates with the inside of the cap portion 7 and the inside of the leg portion 3 when the cover body 6 is attached, and the base portion 2 is provided with a drainage hole 21 that communicates with the inside of the leg portion 3 (FIGS. 3 and 4).

[0043] Therefore, in this embodiment, when the bathtub stand 1 is lowered into a bathtub filled with hot water (water), the water in the bathtub flows into the inside of the cap part 7 and the inside of the leg part 3 through the drainage hole 51 of the sole body 5, while the air inside the cap part 7 and the inside of the leg part 3 is discharged to the outside through the drainage hole 21 of the base part 2, so that the air remaining inside the cap part 7 and the leg part 3 does not generate buoyancy. Therefore, the bathtub stand 1 of this embodiment can be more easily submerged in a bathtub filled with hot water and stably installed on the bottom of the bathtub. In addition, when the bathtub stand 1 is used without hot water (water), the water accumulated on the upper surface (seat surface) of the base part 2 flows into the inside of the leg part 3 and the inside of the cap part 7 through the drainage hole 21, and is then discharged to the outside through the drainage hole 51 of the sole body 5, so that the water accumulated on the upper surface (seat surface) of the base part 2 is prevented from becoming slippery.

[0044] 3 and 9, a substantially circular recess 52 is formed near the center of the bottom surface of the sole body 5, and one suction cup 53 is formed in the center of the recess 52. In this embodiment, the use of suction cup 53 is not essential, but if the bathtub has a smooth bottom surface, the bathtub stand 1 can be installed on the bathtub bottom more stably by using suction cup 53.

[0045] A grip surface 54 is formed on the bottom surface of the sole body 5, on the outer circumferential side of the drainage holes 51 and the recesses 52. A plurality of grooves 55 are formed in a lattice pattern on the grip surface 54, and these grooves 55 form a plurality of rectangular protrusions 56. Therefore, the grip surface 54 is formed in an uneven shape by the plurality of grooves 55 and the plurality of rectangular protrusions 56.

[0046] In addition, the resin material in this specification includes hard resin materials such as polypropylene, polyethylene, ABS (acrylonitrile butadiene styrene), and soft resin materials having a certain elasticity such as elastomers such as synthetic rubber. In addition, elastomer means a general term for polymeric substances having rubber elasticity in a broad sense, and elastomers here include not only synthetic rubber in the narrow sense but also natural rubber. In this embodiment, the sole body 5 is integrally molded by injection molding using synthetic rubber having rubber elasticity at room temperature, and the grip surface 54 and the suction cup 53 are also integrally molded. However, the material of the sole body 5 is not limited to elastomers such as synthetic rubber, and may be other hard resin materials.

[0047] In this embodiment, the bottom surface of the sole portion 4 is divided into a first bottom surface portion 57 arranged in the lower region of the leg portion 3 and a second bottom surface portion 58 arranged in the lower region of the ballast portion 8 (see Figures 3 and 7), and when the sole portion 4 is placed in contact with the ground, the second bottom surface portion 58 may be positioned higher than the first bottom surface portion 57 so that it is separated from the ground surface (not shown).

[0048] In the above configuration, the leg 3 is in contact with the ground via the first bottom surface 57 of the sole portion 4, while the ballast portion 8 is supported by the second bottom surface 58 of the sole portion 4 at a position eccentric to the leg 3 so as to be spaced apart from the installation surface. For this reason, a moment acts on the leg 3 due to the weight of the ballast portion 8, causing it to tip towards the center of gravity of the ballast portion 8, but since the other legs 3 are braced in the direction in which the leg 3 tilts, the bathtub stand 1 can be stably installed in the bathtub simply by attaching one ballast portion 8 to the leg 3.

[0049] FIG. 10 shows a plan view that typically illustrates a platform projection area 34 of a bathtub stand 1 according to one embodiment of the present invention.

[0050] As shown in Figure 10, in the bathtub stand 1 of this embodiment, the ballast section 8 is disposed within a stand projection area 34 surrounded by the outermost line segments 33 connecting adjacent legs 3 in a plan view. Therefore, in this embodiment, when the bathtub stand 1 is installed in the bathtub, the ballast section 8 is prevented from interfering with the bathtub sidewall, making it possible to install the bathtub stand 1 and its legs 3 in contact with or close to the bathtub sidewall.

[0051] As described above, bathtub stand 1 of this embodiment has an extremely simple structure because ballast section 8 attached to leg section 3 functions as the sinking means, and can be easily submerged in a bathtub filled with hot water and stably installed at the bottom of the bathtub. In addition, ballast section 8, which serves as the sinking means, can be attached externally to the outside of leg section 3 or installed later, so as long as bathtub stand 1 has leg section 3, it can be applied and deployed to other bathtub stands.
