Description

  The present invention relates to a handrail for bathing used when a bather such as a disabled person or an elderly person enters or exits a bathtub.

Generally, a person who needs assistance, such as a physically handicapped person or an elderly person, has weak legs and legs, so it is not easy to enter the bathtub at the time of bathing. In this case, the person is moved into the bathtub while being supported by the assistant, for example. There was the present condition that I want to. In the case of a person who needs a wheelchair in this way, for example, when moving between a bed and a wheelchair or when transferring, an assistant or a mobility aid for supporting weight is necessary. The burden was also great.
Therefore, for example, Japanese Patent Application Laid-Open No. H10-228867 proposes an assisting device for transferring to a bed from a wheelchair or the like.
Patent Document 1 discloses a fixed portion that is fixed to a floor surface or a bed, a horizontal portion that extends in a horizontal direction from the fixed portion, a standing portion that rises vertically upward from the horizontal portion, and a fixed portion that extends from the upper portion of the standing portion. Provided with a first handrail portion extending in the horizontal direction toward the side, and further provided with a second handrail portion which is pivoted about the upright portion and arranged at a position parallel to the bed It is what was done. A person requiring assistance using the bed can move between the wheelchair and the bed, for example, by supporting the weight by grasping the first handrail part or the second handrail part by hand, thereby reducing the burden on the assistant. be able to.
Japanese Patent No. 3049240

However, the handrail of Patent Document 1 has the following problems.
In Patent Document 1, the position of the first handrail portion extending between the bed and the fixed portion is fixed, and the second handrail portion rotates around the upright portion. Sufficient space is required in which the second handrail portion can rotate. For this reason, the first and second handrail portions may be arranged so that they do not get in the way of the person requiring assistance or the helper even if the first and second handrail portions described above are arranged as in a hospital room or the like. When the space is limited, there is a problem that it is difficult to use because it is an obstacle to the passage of a wheelchair or the like as well as a person who needs assistance or a person who needs assistance.
Further, in the case of a bed, since a person who needs assistance is specified, the positions of the first and second handrail portions may be in a state where they are easy to use for the person. . However, in the case where an unspecified number of assistants such as a bathtub use it, for example, the direction and the position where it is easy to go in and out of the bathtub from a wheelchair vary from person to person. That is, it is necessary to secure a space on the side of entering and exiting the bathtub according to the user, and in that case, a handrail or the like is appropriately moved. Therefore, in the structure in which the first handrail portion and the fixed portion are fixed with respect to the bed as in Patent Document 1, the first handrail and the fixed portion are removed from the bed, and are adjusted again according to a position where the user can use them. There was a drawback that had to be assembled.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a handrail mechanism for a bathtub that does not get in the way of a bather or an assistant in a small space such as a bathroom.

In order to achieve the above-mentioned object, the handrail mechanism for bathtubs according to the present invention is a handrail mechanism for bathtubs that is attached to a bathtub and assists a bather's operation, and fixes one end of the bathtub and grounds the floor surface. A support plate provided on the other end of the base plate, a support provided on the support, and a handrail provided on the support and extending toward the side wall of the bathtub. It is characterized by being movable to the first position and the second position in the extending direction of the side wall of the bathtub.
In the present invention, the handrail can be moved between the first position and the second position. When the handrail is arranged at the first position, a wide space can be secured on the second position side of the handrail at that position, and the bather can get in and out of the bathtub by grasping the handrail from the second position side. Further, when the handrail is arranged at the second position, a wide space can be secured on the first position side of the handrail at that position. Therefore, for example, it is possible to move and arrange only the handrail so as to secure a space on the side where the bather can easily enter and exit the bathtub.

In the handrail mechanism for bathtubs according to the present invention, the handrail is preferably rotatable between the first position and the second position.
In the present invention, for example, the support portion is a rotary shaft provided so as to be rotatable about the direction from the support column to the bathtub, and the handrail is fixed to the rotary shaft so that the first position and the second position are within the rotation range. Let Thereby, a handrail can be moved to a 1st position and a 2nd position by rotating with a rotating shaft. Thereby, compared with the handrail which rotates centering on the support | pillar like the past, the space required for the movement of a handrail can be reduced.

Moreover, in the handrail mechanism for bathtubs according to the present invention, it is preferable that the handrail be laterally movable between the first position and the second position.
In the present invention, for example, the support portion is a rail provided on the support column and a sliding member slidably engaged with the rail, and the handrail is laterally moved between the first position and the second position along the rail. Can move. Thereby, compared with the handrail which rotates centering on the support | pillar like the past, the space required for the movement of a handrail can be reduced.

Moreover, it is preferable that the handrail mechanism for bathtubs according to the present invention is provided with a lock mechanism for fixing the handrail to a holding state at a predetermined position.
In the present invention, since the handrail can be fixed at a predetermined position, by setting the fixed position in advance, the handrail can be fixed at a position corresponding to the bather's use state. And since a handrail is made into a holding state, it can prevent that a handrail rotates and moves during use of a handrail.

Moreover, in the handrail mechanism for bathtubs according to the present invention, the base plate is preferably provided at the lower part of the bathtub so as to be rotatable about the longitudinal direction of the bathtub.
In the present invention, the attachment portion between the base plate and the lower part of the bathtub serves as a hinge, and the base plate is substantially parallel to the bathroom floor surface with respect to the bathtub installed horizontally regardless of the slope of the bathroom floor surface. Can be grounded

In the handrail mechanism for bathtubs according to the present invention, it is preferable that the column is provided with a height adjusting means for moving the handrail in the vertical direction.
In this invention, since the height of a handrail can be adjusted according to the height of the bather to be used, a bather becomes easy to hold on a handrail.

According to the bathtub handrail mechanism of the present invention, it is possible to move only the handrail so as to secure a space on the side where the bather can easily enter and exit the bathtub without moving the position of the base plate or the column.
In addition, the bathtub handrail mechanism has a structure in which a column and a base plate for connecting the handrail are arranged so as not to be an obstacle to the entrance and exit operation of the bathtub, and the handrail has a first position in the extending direction of the side wall of the bathtub. It is a structure which moves to a 2nd position, and a floor area required in order to install a handrail can be made small compared with the handrail which rotates centering on a support | pillar like the past. Therefore, a handrail can be installed in a bathtub in a bathroom that forms a narrow and limited space without obstructing a bather, an assistant, and a wheelchair.
In addition, bathers using wheelchairs can stand up in the state of grabbing the handrail, move slightly into the bathtub and move into the bathtub, reducing the flow of movement of the bather in and out. This can reduce the burden on bathers. Furthermore, the burden on the assistant can be reduced.

Hereinafter, a handrail mechanism for bathtubs according to an embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, the handrail mechanism 1 for a bathtub is arranged fixedly on the outside of a bathing apparatus 10, for example, a bather whose legs are weak such as a disabled person or an elderly person, This is an aid for supporting the body when transferring onto the seat 12.
In addition, the code | symbol M shall be the bather who bathes using the bathing apparatus 10, and the code | symbol K shall be the wheelchair which the bather M uses. And the bather M and the wheelchair K are shown only in FIG. 1 and omitted in other drawings, but in these drawings, description will be made using the symbols M and K.

First, the structure of the bathing apparatus 10 which attaches the handrail mechanism 1 for bathtubs is demonstrated based on drawing.
As shown in FIG. 1 and FIG. 2, the bathing apparatus 10 includes a bathtub 11 having a substantially rectangular shape in plan view provided with an entrance opening 11 a serving as an entrance / exit of a bather M on one side wall 11 b, and ascending and descending in the bathtub 11 (arrows). E1 direction) and the bathtub sheet 12 provided so as to be laterally movable (arrow E2 direction) in the longitudinal direction of the bathtub 11, and rotatable on the bathtub sheet 12 and laterally movable in the short direction of the bathtub 11 (arrow E3 direction) And a lift door 14 that moves in the vertical direction and forms the inlet opening 11a in the bathtub 11.
The bathtub sheet 12 is given a driving force for moving up and down or laterally by the sheet driving unit 15. In addition, a handrail fixing portion 20 for attaching the bathtub handrail mechanism 1 to a position below the elevating door 14 is provided on the lower side wall 11c of the bathtub 11 (see FIGS. 2 and 3).

As shown in FIG. 1, the seat drive unit 15 that drives the bathtub sheet 12 includes a first guide rail 15 a that extends in the longitudinal direction of the bathtub 11 at one upper side edge 11 d of the bathtub 11 (see FIG. 2). ), And a drive main body 15b that slides along the first guide rail 15a, and a second guide rail 15c that extends in the vertical direction from the drive main body 15b toward the bottom of the bathtub 11.
And the one end 12a of the bathtub sheet | seat 12 is attached to the 2nd guide rail 15c so that a movement is possible. Thereby, the bathtub sheet 12 can be moved up and down in the bathtub 11 and reciprocated in the longitudinal direction of the bathtub 11 by being guided by the first guide rail 15 a and the second guide rail 15 c by the seat driving unit 15. It is the structure which can be arrange | positioned in the arbitrary positions in the bathtub 11. FIG.

Moreover, the seat part 13 shown in FIG.1 and FIG.2 comprises the thin-plate shaped seat part of planar view circle shape, and as mentioned above, it is provided in the upper surface of the bathtub sheet | seat 12 so that rotation around the vertical axis line is possible. Furthermore, this seat part 13 has a function which slides in the transversal direction (arrow E3 direction) of the bathtub 11 with respect to the bathtub sheet | seat 12. As shown in FIG.
That is, as shown in FIGS. 2 and 3, when a later-described elevator door 14 is lowered and the entrance opening 11 a is open, a part of the seat portion 13 projects outward from the bathtub 11. It has become. Therefore, for example, when the bather M enters the bathtub 11, he / she sits in a state where his / her feet are out of the bathtub 11 (that is, a state in which the body is directed in the front direction) first, and then the seat portion. By rotating 13, the direction of the body can be moved to the bathing position in the bathtub 11 so that the foot enters the bathtub 11.

As shown in FIGS. 1, 2, and 3, the elevating door 14 is a member that forms part of the side wall of the bathtub 11. And the guides 14a and 14a extended in the substantially up-down direction are provided in the both ends of one side wall 11b of the bathtub 11, and the raising / lowering door 14 can be moved to the up-down direction manually or automatically along the guides 14a, 14a. It has become. By this vertical movement, an inlet opening 11 a is formed in the upper part of the side wall 11 b of the bathtub 11.
Although not particularly illustrated, the space between the bathtub 11 and the elevating door 14 is sealed in a liquid-tight manner.

As shown in FIG. 4, the handrail fixing portion 20 extends outward from the bathtub lower frame 21 through a connecting member 21 </ b> A and an L-shaped bathtub lower frame 21 fixed to the side wall lower portion 11 c of the bathtub 11. Projecting member 22. The protruding member 22 has a prismatic shape that is long in the longitudinal direction of the bathtub 11, and has holes (not shown) in which female screws are formed at both ends 22a and 22b (see FIG. 3). A connecting portion 34 provided at the 30 bath-side end portion 30 a is fixed by a locking screw 35.
The protruding member 22 is located below the elevating door 14, and the protruding member 22 is exposed when the elevating door 14 is in the raised position and the inlet opening 11a is closed. When the person M enters the bathtub 11, the elevating door 14 is lowered, and the protruding member 22 is substantially hidden from the lower surface of the elevating door 14, so that the bather M is not disturbed.

Next, the handrail mechanism 1 for bathtubs provided on the side of the bathtub 11 will be described based on the drawings.
As shown in FIG. 5, the bathtub handrail mechanism 1 is orthogonal to the side wall 11 b of the bathtub 11 at a thin plate-like base plate 30, a column 31 standing on the base plate 30, and an upper end 31 a of the column 31. A rotation shaft 32 (support portion) supported rotatably in the direction, and a handrail body 40 extending horizontally toward the bathtub 11 side at the bathtub side end portion 32a of the rotation shaft 32 ( (See FIG. 6). The bathtub handrail mechanism 1 at this time is disposed at a substantially central position in the longitudinal direction of the bathtub 11.
The other end 32b of the rotating shaft 32 is provided with a lock mechanism 50 that holds the handrail body 40 in a fixed state at predetermined positions (a first fixed position R1 and a second fixed position R2 described later).

As shown in FIGS. 4 and 5, the base plate 30 has a substantially rectangular shape in a plan view, and at both corners of one end 30 a on the bathtub 11 side in the longitudinal direction, connecting portions projecting upward from the base plate 30. 34 is provided. And both the connection parts 34 and 34 are the female screw holes (illustration omitted) formed in the both ends 22a and 22b (refer FIG. 3) of the protrusion member 22 of the handrail fixing | fixed part 20 with the locking screws 35 and 35 in which the external thread was formed. ) Is engaged with the bathtub 11 so as to be rotatable.
Thereby, the attachment part of this connection part 34 and the projection member 22 plays the role of a hinge. That is, since the base plate 30 is configured to rotate around the locking screw portions 35, 35, the base plate 30 can be grounded in a state substantially parallel to the bathroom floor F regardless of the slope of the bathroom floor. (See FIG. 2). That is, the base plate 30 can be attached to a bathtub installed horizontally in a bathroom with a sloped floor.
Further, the support post 31 is erected on the other end 30b of the base plate 30 as described above.

  Further, as shown in FIGS. 1 and 2, an anti-slip mat 33 is provided on the upper surface of the base plate 30. Although details will be described later, when the bather M enters the bathtub 11 using the bathtub handrail mechanism 1, the mat moves to the bathtub sheet 12 in the bathtub 11 with his feet on the mat 33. 33 is made of a non-slip material such as rubber.

  As shown in FIGS. 1 and 2, the support column 31 is fixed to the base plate 30 by means of fixing (not shown) such as bolts or welding, that is, the other end 30b of the base plate 30 (the side opposite to the bathtub 11), that is, the bather M or the assistance. It is provided at a position away from the side wall 11b of the bathtub 11 at a predetermined interval so that the person's foot hits the support column 31 and does not get in the way.

As shown in FIGS. 3 and 5, the handrail main body 40 is fixed to the bathtub-side end portion 32 a of the rotation shaft 32 via an interposition member 43, and is in a direction orthogonal to the axis I forming the central axis of the rotation shaft 32. A connection frame 41 having a substantially U-shape (see FIG. 3) extending in front view, and a handrail 42 fixed so as to extend from the tips 41a and 41a of the connection frame 41 toward the side wall 11b of the bathtub 11. Consists of. The interposition member 43 is a plate-like member, and is interposed between the rotating shaft 32 and the handrail main body 40 so as to fix the both.
Such a handrail 42 is fixed at a substantially right angle with respect to the connection frame 41 so as to be substantially L-shaped.

As shown in FIG. 2, the handrail 42 includes horizontal frames 42a and 42b extending in parallel in the horizontal direction, and vertical frames 42c and 42d that connect the ends of the horizontal frames 42a and 42b. It is shaped like a substantially rectangular frame that is long in the direction of the axis I.
In addition, the length of the handrail 42 in the longitudinal direction is set to a length sufficient for the bather M to take a space when performing the entrance / exit operation to the bathtub 11.

Such a handrail main body 40 is configured to rotate about the axis I together with the rotation shaft 32 (in the direction of arrow E5 shown in FIG. 3). Since the handrail 42 is fixed via the connection frame 41, the handrail 42 is in an eccentric state with respect to the rotation shaft 32. Therefore, the handrail 42 can be moved and arranged at symmetrical positions (first fixed position R1 and second fixed position R2) across the axis I of the rotating shaft 32.
Here, the first fixed position R1 (first position) is a position where the horizontal frames 42a and 42b (see FIG. 2) of the handrail 42 are arranged in the vertical direction on the right side of the rotation shaft 32 in the front view shown in FIG. The second fixed position R2 (second position) is also a position where the horizontal frames 42a and 42b (see FIG. 2) of the handrail 42 are arranged in the vertical direction on the left side of the rotation shaft 32. The rotation range of the handrail 42 is a range of 180 degrees between the first fixed position R1 and the second fixed position R2.

And as shown in FIG. 3, the handrail 42 can select either one of two places, the first fixed position R1 and the second fixed position R2. For example, when the handrail 42 is disposed at the first fixed position R1, the bather M is located on the left side of the handrail 42 in FIG. 3, that is, on the second fixed position R2 side (in FIG. It is possible to secure a wider space than the right side of the handrail 42. On the other hand, when the handrail 42 is arranged at the second fixed position R2, the right side of the handrail 42 in FIG. 3, that is, the first fixed position R1 side (lower side of the page with respect to the handrail 42 in FIG. 1) becomes the entrance to the bathtub 11. A wider space than the left side of the handrail 42 can be secured. Therefore, only the handrail 42 can be moved so as to secure a space on the side where the bather M easily enters and exits the bathtub 11.
The height and position of the handrail 42 are such that when the bather M stands up with his feet on the mat 33, the handrail 42 (the horizontal frames 42a and 42b) can be gripped.

Next, a lock mechanism 50 for holding the handrail body 40 in a fixed state at a predetermined position (first fixed position R1 and second fixed position R2) will be described with reference to FIG.
As shown in FIG. 6, the lock mechanism 50 has a function of fixing the rotation of the handrail body 40 at a predetermined position (first fixed position R1 or second fixed position R2).
Specifically, the lock mechanism 50 includes a mounting plate 55 fixed to the other end 32b of the rotating shaft 32, and a stopper provided on the mounting plate 55 and energized in the direction of the bathtub 11 with a spring 52 incorporated therein. It consists of a pin 51 and a locking member 53 which is fixed to the column 31 and has locking holes 53a and 53b for locking the tip locking portion 51a of the stopper pin 51.

The stopper pin 51 is fixedly supported by a mounting plate 55 attached to the other end 32b of the rotary shaft 32 by a bolt 54, 54 while being biased toward the bathtub 11 side. The attachment plate 55 is connected to the handrail body 40 via the rotation shaft 32. Therefore, the stopper pin 51 is configured to rotate together with the shaft rotation of the handrail 42 (rotating shaft 32).
The locking holes 53a and 53b formed in the locking member 53 are coaxial with each other when the stopper pin 51 stops at each of the first fixed position R1 and the second fixed position R2. As a result, the stopper pin 51 has the leading end locking portion 51a in one of the locking holes 53a and 53b regardless of whether the handrail 42 is disposed at the first fixed position R1 or the second fixed position R2. It is latched and the handrail 42 can be locked.

More specifically, when the stopper pin 51 that rotates with the rotation of the handrail 42 reaches a position that matches the locking hole 53a (53b) for locking, the stopper pin 51 is moved to the bathtub 11 side by the biasing force of the spring 52. Is moved to be inserted into the locking hole 53a (53b). Accordingly, since the stopper pin 51 is biased by the spring 52, the handrail 42 is automatically locked without coming out of the locking hole 53a (53b). As described above, since the handrail 42 is held, it is possible to prevent the handrail 42 from rotating and moving while the handrail 42 is in use.
Further, in order to release the locked state by the locking mechanism 50, the stopper pin 51 is moved to the opposite side to the bathtub 11 (in the direction of arrow E4 shown in FIG. 6), and the tip locking portion 51a is resisted against the urging force of the spring 52. Is pulled out from the locking hole 53a (53b). Thereby, the locked state can be released.

Next, a bathing method using the bathing apparatus 10 and the handrail mechanism 1 for a bath configured as described above will be described with reference to the drawings.
Here, the position where the bather M enters and exits the bathtub 11 is appropriately selected as a position where the bather M can easily enter the bathtub 11, but in the following description, as shown in FIG. Suppose that the bathtub 11 is entered from a position above the paper surface (left side with respect to the handrail 42 in the side view of FIG. 3). Therefore, the bathtub sheet 12 in the bathtub 11 is also arranged on the side that enters and exits. Furthermore, hot water is put in the bathtub 11, the raising / lowering door 14 is lowered | hung, the entrance opening 11a of the bathtub 11 is made into the open state, and a part of seat part 13 is made into the position which protruded from the entrance opening 11a. Moreover, the bather M demonstrates as what uses the wheelchair K for normal movement.
Further, the handrail 42 is arranged and fixed at the first fixed position R1. At this time, the lock mechanism 50 is brought into a state where the distal end locking portion 51a of the stopper pin 51 enters and is locked into the first locking hole 53a (see FIG. 6). In addition, before using the handrail 42, for example, an assistant preferably confirms that the lock mechanism 50 is in a locked state.

  First, as shown in FIG. 1, the wheelchair K on which the bather M is riding is placed on the bathtub 11. Then, the bather M gets his feet on the mat 33 and stands up while holding his / her own weight by grasping the horizontal frame 42a (42b) of the handrail 42 with his / her hand. Further, the body is rotated approximately 45 degrees to move from the entrance opening 11 a into the bathtub 11 and sit on the seat portion 13. Then, the bather M puts his / her foot into the bathtub 11 while rotating the seat portion 13 and laterally moving in the lateral direction of the bathtub 11, and the transfer is completed.

  Next, the elevating door 14 is raised to close the inlet opening 11b of the bathtub 11, and then the bathtub sheet 12 is lowered, so that the bather M enters hot water by adding hot water as necessary. In addition, when leaving the bathtub 11, it is set as the reverse procedure when entering the bathtub 11, the raising / lowering door 14 is lowered | hung, and the bathtub sheet | seat 12 and the seat part 13 are moved to a predetermined position. Then, the bather M puts his feet on the mat 33, grabs the handrail 42, rises on the mat 33, and sits down on the wheelchair K placed side by side to complete the bathing.

  In this way, by using the bathtub handrail mechanism 1, it is possible to minimize the flow line in the operation of the bather M entering and leaving the bathtub 11. As another purpose of using the handrail 42, it is needless to say that it can be used not only when entering and leaving the bathtub 11, but also when, for example, the bather M who has moved in the wheelchair K stands while holding the handrail 42 to wash his body. Yes.

In the bathtub handrail mechanism according to the above-described embodiment, only the handrail 42 is moved so as to secure a space on the side where the bather M can easily enter and exit the bathtub 11 without moving the positions of the base plate 30 and the column 31. be able to.
Further, the bathtub handrail mechanism 1 has a structure in which the column 31 and the base plate 30 that connect the handrail 42 are arranged so as not to obstruct the operation of entering and exiting the bathtub 11, and the handrail 42 is provided on the side wall 11 b of the bathtub 11. Compared with a handrail that rotates around a support column as in the prior art, the floor area required to install the handrail 42 is a configuration that moves between the first fixed position R1 and the second fixed position R2 in the extending direction. Can be small. Therefore, the handrail 42 can be installed in the bathtub in the bathroom that forms a narrow and limited space without obstructing the bather M, the assistant, and the wheelchair K.
Furthermore, since the bather M who uses the wheelchair K can stand up while holding the handrail 42 and can move into the bathtub 11 while slightly shifting his / her body toward the bathtub 11, The number of lines can be reduced, and the burden on the bather M can be reduced. Furthermore, the burden on the assistant can be reduced.

Next, first and second modified examples of the embodiment of the present invention will be described with reference to FIGS. 7 and 8, and the same or similar members and parts as those of the above-described embodiment are denoted by the same reference numerals. A description will be omitted, and a configuration different from that of the embodiment will be described.
First, FIG. 7 is a figure which shows the 1st modification of the handrail mechanism for bathtubs.
As shown in FIG. 7, the handrail mechanism 1 for a bathtub according to the first modification is configured such that the column 31 has a double structure and the height of the handrail body 40 can be adjusted. The support column 31 includes an outer support column 31A fixed to the other end 30b of the base plate 30 and an inner support column 31B inserted inside the outer support column 31A so as to be movable in the vertical direction. And the structure etc. in which the handrail main body 40 and the locking mechanism 50 are provided in the upper end 31a of the inner side support | pillar 31B via the rotating shaft 32 are the structures similar to embodiment.
A height adjusting screw 37 (height adjusting means) is provided on the upper part 31b of the outer support 31A. By loosening this, the inner support 31B moves in the vertical direction (arrow E6 direction), and the floor The height in the vertical direction from the surface F can be adjusted, and by tightening the height adjusting screw 37, the inner support column 31B can be fixed to the outer support column 31A so as not to be relatively movable. Thereby, since the height of the handrail 42 can be adjusted according to the height of the bather to be used, the bather M is easily gripped by the handrail 42.

Next, FIG. 8 is a figure which shows the 2nd modification of the handrail for bathtubs.
As shown in FIG. 8, in the bathtub handrail 1 according to the second modified example, instead of the rotary shaft 32 (see FIG. 2) of the embodiment, the handrail 42 is replaced with the first fixed position R1 and the first fixed position R1 as in the embodiment. 2 It is possible to move laterally between the fixed positions R2 (see FIG. 1). Specifically, a plate-like base 62 is provided on the bathtub 11 side of the upper end 31a of the column 31 so that the longitudinal direction thereof is substantially parallel to the extending direction of the side wall 1a of the bathtub 11, and the bathtub 11 of the base 62 is provided. The rail 60 (support part) is attached to the side.
A sliding member 61 (support portion) that is slidably engaged with the rail 60 is fixed to the handrail body 40. Thereby, the handrail 42 is moved laterally along the rail 60, and the first fixed position R1 and the second fixed position R2 shown in FIG. 1 can be selectively arranged.

As mentioned above, although embodiment of the handrail mechanism for bathtubs by the present invention, the 1st, and the 2nd modification were explained, the present invention is not limited to the above-mentioned embodiment, the 1st, and the 2nd modification, Changes can be made as appropriate without departing from the spirit of the invention.
