As a result, the user of the bathtub 10 can select the fixed handrail to be used according to his/her own physique and ease of use, thereby improving convenience.

(support member)
Next, the configuration of the support member 30 will be described with reference to FIGS. 4 to 8. FIG. FIG. 4 is a sectional view taken along line II' in FIG. FIG. 6 is a cross-sectional view at a position corresponding to the II' cross section in FIG. 3, with the movable handrail 25 between the upright state and the reclined state. FIG. 8 is a cross-sectional view at a position corresponding to the II' cross section in FIG. 3 when the movable handrail 25 is in an upright state. FIG. 5 is a cross-sectional view taken along line AA' in FIG. 7 is a cross-sectional view taken along the line BB' in FIG. 6. FIG. The support member 30 rotatably supports the base end of the handrail bar 26 with the lower handrail 21 as a rotation axis. Moreover, the support member 30 is provided so as to be movable in the axial direction of the lower handrail 21 . As shown in FIG. 4 , the support member 30 includes a body portion 31 and a rotation support member 32 .

(main body)
As shown in FIG. 4, the body portion 31 is a housing-like member that incorporates a tubular portion 33 and the like, which will be described later. The lower handrail 21 penetrates through the body portion 31 via the opening 31A shown in FIG. That is, the lower handrail 21 is inserted through the opening 31A. Thereby, the body portion 31 is movable in the axial direction of the lower handrail 21 . The inner wall of the body portion 31 is provided with a body convex portion 31B projecting toward a tubular portion 33, which will be described later. Further, the body portion 31 is provided with a front opening portion 31C, and a handrail bar support portion 34, which will be described later, protrudes from the front opening portion 31C.

The body portion 31 further has a pressed portion 35 on the opposite side of the body convex portion 31B with the cylindrical portion 33 interposed therebetween. The pressed portion 35 is a member that contacts the outer peripheral surface of the tubular portion 33 and is pressed by a pressing portion 33A provided on the outer peripheral surface of the tubular portion 33 . The pressed portion 35 is provided with a projecting portion 35</b>A projecting toward the cylindrical portion 33 . The projecting portion 35A contacts the pressing portion 33A or the relaxing portion 33B of the tubular portion 33 . A specific example of the pressed portion 35 is an elastic body such as a plate spring member. Both longitudinal ends of the pressed portion 35 are supported by the body portion 31 , and a longitudinal intermediate portion of the pressed portion 35 is in contact with the cylindrical portion 33 .

(Rotating support member)
The rotating support member 32 is a member provided in the body portion 31 and has a cylindrical portion 33 and a handrail bar support portion 34 connected to the cylindrical portion 33 . The cylindrical portion 33 is a substantially cylindrical portion provided inside the body portion 31 of the rotation support member 32 . The inner diameter of the cylindrical portion 33 is set slightly larger than the outer diameter of the lower handrail 21 , and the lower handrail 21 is inserted through the inner peripheral side of the cylindrical portion 33 . That is, the tubular portion 33 is provided on the lower handrail 21 so as to be rotatable and axially movable.

The tubular portion 33 has pressing portions 33A1 and 33A2 on the outer peripheral surface of both ends in the axial direction. The pressing portions 33A1 and 33A2 press the pressed portion 35 when the handrail bar 26 is in the laid down state or the standing state. Specifically, the pressing portions 33A1 and 33A2 are portions of the outer peripheral surface of the tubular portion 33 that have a larger outer diameter than the relaxation portion 33B described later. In particular, the outer peripheral surface of the tubular portion 33 is used as it is for the pressing portions 33A1 and 33A2.

The cylindrical portion 33 has relief portions 33B at positions adjacent to the pressing portions 33A1 and 33A2 on the outer peripheral surface of both ends in the axial direction. The relieving portion 33B relieves the pressing force on the pressed portion 35 more than the pressing force of the pressing portions 33A1 and 33A2. Specifically, the relief portion 33B is a recessed portion having an outer diameter smaller than that of the pressing portions 33A1 and 33A2 on the outer peripheral surface of the cylindrical portion 33 . More specifically, as shown in FIG. 4, concave portions 33D1 and 33D2 are provided on the outer peripheral surface of the cylindrical portion 33. As shown in FIG. A convex portion 33E is provided between the cylindrical portion 33 and the concave portions 33D1 and 33D2, as shown in FIG. Such a convex portion 33E abuts on the main body convex portion 31B in the intermediate state.

The handrail bar support portion 34 is a portion of the rotation support member 32 that supports the base end portion of the handrail bar 26 . The handrail bar support portion 34 protrudes outward (in the X direction in FIG. 4) of the body portion 31 from a front opening portion 31C provided in a concave portion provided in the middle portion of the body portion 31 in the Y direction. . The handrail bar support portion 34 can move up and down as the handrail bar 26 rotates within the front opening 31C. In this way, the rotational movement of the handrail bar 26 of the movable handrail 25 is transmitted to the cylindrical portion 33 via the handrail bar support portion 34 , so that the cylindrical portion 33 becomes the shaft of the lower handrail 21 of the handrail bar 26 . Rotation is possible in conjunction with rotation with the direction as the rotation center.

Since the pressed portion 35 is a leaf spring member, even if the outer dimensions of the lower handrail 21 change in the axial direction, such as when the lower handrail 21 is provided with dimples (uneven shape), the leaf spring member can be Elastic deformation can absorb the displacement of the cylindrical portion 33 . When the cylindrical portion 33 is brought into contact with the lower handrail 21 at either concave or convex position among the unevenness of the dimples provided on the lower handrail 21 and fixed, the gripping force is appropriately set by the leaf spring member. be. In particular, when the cylindrical member is fixed at the convex position of the lower handrail 21, it is possible to suppress damage to the resin coating of the lower handrail 21 by the leaf spring member.

(Regulation of axial movement of movable handrail)
Next, a specific example of restricting movement of the lower handrail 21 along the axial direction by the support member 30 will be described with reference to FIGS. 4 to 8. FIG. As shown in FIGS. 4 and 5, when the movable handrail 25 is laid down, the projecting portion 35A contacts the pressing portion 33A1 of the cylindrical portion 33, and the body convex portion 31B contacts the concave portion of the cylindrical portion 33. It is in contact with 33D1. Therefore, the central axis of the tubular portion 33 is eccentric in the X direction with respect to the opening 31A of the main body portion 31 . As a result, the outer peripheral surface of the lower handrail 21 on the −X direction side comes into contact with the inner peripheral surface of the cylindrical portion 33 on the −X direction side, and the outer peripheral surface of the lower handrail 21 on the +X direction side contacts the opening of the main body portion 31. It contacts the inner peripheral surface of 31A on the +X direction side. At this time, the pressed portion 35 is pressed by the pressing portion 33 A of the cylindrical portion 33 , and the body portion 31 receives a reaction from the pressed portion 35 . As a result, the lower handrail 21 is pressed by the inner peripheral surface of the cylindrical portion 33 and the opening 31A of the main body portion 31 .

That is, as shown in FIG. 5, when the movable handrail 25 is laid down, the lower handrail 21 is sandwiched between the inner peripheral surface of the tubular portion 33 and the opening 31A of the main body portion 31. axial movement of is restricted. Thus, the axial movement of the support member 30 is restricted.

As shown in FIG. 6, when the handrail bar 26 of the movable handrail 25 is rotated to the intermediate state, the projecting portion 35A contacts the relaxing portion 33B of the cylindrical portion 33, and the main body convex portion 31B moves toward the cylindrical portion 33. is in contact with the convex portion 33E. Therefore, as shown in FIG. 7, the central axis of the tubular portion 33 is closer to the central axis side of the opening 31A of the main body portion 31 than when the movable handrail 25 is in the laid down state. As a result, a gap is generated along the entire circumference between the inner peripheral surface of the cylindrical portion 33 and the outer peripheral surface of the lower handrail 21 , and the opening 31 A of the main body portion 31 is separated from the lower handrail 21 .

That is, as shown in FIG. 7, in the intermediate state of the movable handrail 25, the clamping of the lower handrail 21 between the inner peripheral surface of the cylindrical portion 33 and the opening 31A of the main body portion 31 is relaxed, and the cylindrical portion 33 and the main body portion are separated from each other. 31 is released from movement in the axial direction.

Further, as shown in FIG. 7, in the intermediate state of the movable handrail 25, the projecting portion 35A of the pressed portion 35 is inserted into the relaxing portion 33B of the cylindrical portion 33. As shown in FIG. In this case, the side end face (Y-direction end face) of the projecting portion 35A and the recessed side wall face (Y-direction wall face) of the relief portion 33B abut against each other, and the cylindrical portion 33 and the pressed portion 35 move in the Y direction. It is in an engaged state. As a result, when the handrail bar support portion 34 receives an input of axial movement via the handrail bar 26, the force is transmitted from the cylindrical portion 33 to the pressed portion 35, and the main body portion to which the pressed portion 35 is attached. 31 also moves along the axial direction of the lower handrail 21 .

As shown in FIG. 8, when the movable handrail 25 is in an upright state, the protrusion 35A contacts the pressing portion 33A2 of the cylindrical portion 33, and the main body convex portion 31B contacts the concave portion 33D2 of the cylindrical portion 33. . When the pressing portion 33A2 and the projecting portion 35A of the pressed portion 35 come into contact with each other, the lower handrail 21 is pressed by the inner peripheral surface of the cylindrical portion 33 and the opening 31A of the main body portion 31 due to the reaction force from the pressed portion 35. be.

5, in the upright state of the movable handrail 25, the lower handrail 21 is sandwiched between the inner peripheral surface of the cylindrical portion 33 and the opening 31A of the main body portion 31, and the shaft of the cylindrical portion 33 and the main body portion 31 is held. Directional movement is restricted. As a result, axial movement of the support member 30 is restricted.

As described above, the lower handrail 21 is sandwiched between the inner peripheral surface of the opening 31A, which is a predetermined portion of the main body 31, and the inner peripheral surface of the tubular portion 33 when the handrail bar 26 is in the upright state or the downed state. and the axial movement of the support member 30 is restricted. As a result, when the movable handrail 25 is in the upright state or the laid down state, the axial movement of the support member 30 is restricted, and the movable handrail 25 is firmly fixed on the base end side. In addition, since the lower handrail 21 is clamped and fixed by the inner peripheral surface of the opening 31A and the inner peripheral surface of the cylindrical portion 33, the lower handrail 21 does not need to be provided with a separate structure and processing for fixing. , the fixing of the movable handrail 25 can be realized.

Further, as a result of the body portion 31 being displaced as it rotates by the rotating support member 32 connected to the handrail rod 26, the lower handrail 21 is sandwiched between the opening 31A and the inner peripheral surface of the tubular portion 33, and the supporting member 30 axial movement of is restricted. As a result, the movable handrail 25 is fixed on the base end side in conjunction with the rotation of the handrail bar 26 .

The pressing force against the lower handrail 21 can be adjusted by adjusting the strength of the pressed portion 35, which is a plate spring member, and the fixing position to the main body portion 31 by the fixing screw.

(wall roller)
Next, the configuration of the support member 30 will be described with reference to FIGS. FIG. 9 is a rear view showing a configuration example of the support member 30 according to this embodiment. FIG. 10 is a cross-sectional view showing a configuration example of the support member according to the embodiment, and is a cross-sectional view taken along line II-II' in FIG. As shown in FIG. 9, the body portion 31 is further provided with wall surface rollers 37 . The wall surface roller 37 is a rotating member that rolls in contact with the bathroom wall surface 17 of the bathroom. The wall surface roller 37 is provided in the body portion 31 at a position facing the bathroom wall surface 17 of the bathroom (position opposite to the handrail bar 26 side). The wall surface roller 37 is pivotally supported by a pin 37A inserted through the body portion 31 in the Z direction. As shown in FIG. 9 , four wall surface rollers 37 are provided on the body portion 31 . The outer peripheral side of the wall surface roller 37 protrudes toward the bathroom wall surface 17 side from the end surface of the body portion 31 on the bathroom wall surface 17 side. A wall surface roller 37 interposed between the body portion 31 and the bathroom wall surface 17 allows the movable handrail 25 to move more smoothly in the axial direction of the lower handrail 21 . In other words, since there is a gap between the lower handrail 21 and the tubular portion 33 , the body portion 31 may come into contact with the bathroom wall surface 17 . At this time, since the wall surface rollers 37 guide the main body 31 so that it does not resist movement, the position of the movable handrail 25 can be changed easily and accurately. As a result, the fixed handrail is provided at an optimum position in the axial direction, and the movable handrail 25 can be smoothly moved after the restriction on the axial movement of the movable handrail 25 is released.

Moreover, the wall surface roller 37 is formed from a member having a predetermined elasticity. For example, the wall surface roller 37 is made of synthetic resin, synthetic rubber, or the like. Since the wall surface rollers 37 have a predetermined elasticity, the movable handrail 25 is fixed in an upright state or a fallen state. 17 can be prevented from being damaged, and the main body 31 can come into contact with the bathroom wall surface 17 when the movable handrail 25 is in the upright state or the collapsed state. The number of wall surface rollers 37 is not particularly limited as long as it enables smooth sliding between bathroom wall surface 17 and main body 31 . For example, the wall surface rollers 37 may be provided one each on the top and bottom of the body portion 31 .

(handrail roller)
As shown in FIGS. 9 and 10, the body portion 31 is further provided with handrail rollers 39 . The handrail roller 39 is a rotating member that is pivotally supported by a pin 39A that is inserted in the X direction inside the main body, and that rolls while contacting the outer peripheral surface of the lower handrail 21 . By providing the handrail roller 39, the axial movement of the lower handrail 21 of the movable handrail 25 becomes smoother, and the horizontal position of the movable handrail 25 can be changed easily and accurately. As a result, the fixed handrail is provided in an optimal axial position.

In particular, the handrail roller 39 is arranged so as to abut on the outer peripheral surface of the lower handrail 21 on the upper side in the vertical direction (the Z direction in FIG. 10). As a result, the weight of the movable handrail 25 including the main body 31 makes it easier for the handrail roller 39 to contact the lower handrail 21 , and the movable handrail 25 moves smoothly via the handrail roller 39 . Therefore, the horizontal position of the movable handrail 25 can be changed easily and accurately. As a result, the fixed handrail is provided at an optimum position in the axial direction, and the movable handrail 25 can be smoothly moved after the restriction on the axial movement of the movable handrail 25 is released.
