Description

The present invention relates to a toilet handrail device used by assembling a Western-style toilet bowl.

As a toilet handrail device used by assembling to a Western-style toilet bowl, for example, as shown in FIG. 1 of Patent Document 1, a pair of left and right base members 11a having a support support portion 11c are connected to pass in front of the toilet bowl 50. The integrated frame 11 connected by the member 11b, the pair of left and right column members 12 attached to the respective column mounting portions 11c in the integrated frame 11 and erected on the left and right sides of the toilet bowl 50, and the rotation with respect to the upper part of the column member 12. Proposed ones are provided with an armrest 13 attached in a movable state and a backrest 14 integrated with the armrest 13. In this toilet handrail device, the backrest 14 is rotated integrally with the armrest 13, so that the backrest 14 can be arranged at a desired position on the front surface of the toilet seat lid 51.

If you install this kind of toilet railing device,
[1] When standing and sitting (the movement of sitting on the toilet seat and the movement of standing up from the toilet seat; the same applies hereinafter), it is possible to grasp the armrest or lean on the armrest so that the person can stand and sit comfortably. Become.
[2] The posture during defecation can be stabilized.
The merit is obtained.
For this reason, this type of toilet handrail device is suitable for installation in a home with a physically handicapped person or a facility used by such a person.

Moreover, in Japan, the aging of the population is progressing rapidly, and it is expected that social security costs such as long-term care and medical expenses will further increase. For this reason, in recent years, it has been pointed out that it is important to prevent frailty syndrome (a state in which muscle strength and activity are reduced due to aging). In this respect, the toilet handrail device of Patent Document 1 is also useful for preventing frailty.

That is, when the handrail device for toilets of Patent Document 1 is installed, it is possible to stand in front of the toilet bowl and squat while grasping the armrest 13, sit on the toilet bowl, twist the waist while grasping the armrest 13, or use the backrest 14. You can perform exercises such as putting your hips on your back and bending your upper body backwards. Frailty can be prevented by continuing such exercise daily.

In addition, there are many people in the world who are suffering from constipation, and the toilet handrail device of Patent Document 1 can support comfortable stools and prevent constipation. ..

That is, the internal organs can be stimulated by performing the above-mentioned exercises of twisting the waist and bending the upper body. Performing this type of exercise before defecation makes it easier for people with constipation to have a bowel movement. In addition, when sitting on the toilet seat, the arm rest 13 can be placed on the armrest 13 or the backrest 14 can be placed on the back to stabilize the posture in which defecation is easy.

Japanese Patent No. 6817665

As described above, the toilet handrail device of Patent Document 1 not only supports a physically handicapped person, but also helps prevent frailty and constipation. However, in the toilet handrail device of Patent Document 1, the degree of freedom in adjusting the orientation of the armrest 13 is low, and it may be difficult to use the armrest 13 in an appropriate state. For example, in the toilet handrail device of Patent Document 1, when each armrest 13 is rotated inward in order to narrow the distance between the left and right armrests, the armrest on the left side of the paper surface of FIG. 1 (a) of the same document is rotated. Like 13, the tip of the armrest 13 faces inward. Therefore, it is difficult to put the arm on the armrest 13 when the arm is turned in the front-rear direction. The same can be said for the backrest 14.

The present invention has been made to solve the above problems, and provides a toilet armrest device that has a high degree of freedom in adjusting the direction of the armrest and is easy to use in an appropriate state.

The above issues are
A toilet handrail device that is used by assembling it on a Western-style toilet bowl.
An integral frame in which a pair of left and right base members having a first shaft branch at a position in front of the center of the toilet seat are connected by a connecting member passing in front of the toilet bowl.
A first lower rotating member that is attached to the first shaft branch in a horizontally rotatable state and has a second shaft branch at a position that is horizontally offset from the first shaft branch.
Provided with a first upper rotating member having a backrest that is attached to the second shaft branch in a horizontally rotatable state and is provided integrally behind the armrest (at least in a state where it does not move in the horizontal direction). By
The solution is to provide a toilet railing device that allows the armrests and backrest to be translated horizontally.

In the handrail device for toilets of the present invention, the armrest (handrail portion) can rotate horizontally around two rotation centers (first shaft branch and second shaft branch) that are not on the same straight line. It has become. Therefore, in order to narrow the distance between the left and right armrests, it is possible to translate each armrest even when each armrest is moved inward. Therefore, it is possible to change the distance between the armrests while keeping the armrests parallel.

In addition, the toilet handrail device of the present invention is also provided with a backrest. Therefore, it is possible to perform exercises such as putting the hips on the backrest and bending the upper body to the rear side. Therefore, it becomes easier to prevent the above-mentioned frailty syndrome and constipation. Since this backrest is integrally provided behind the armrest, it rotates horizontally together with the armrest. Therefore, the armrest can also be translated.

In the toilet handrail device of the present invention,
A rear leg is further provided that is mounted horizontally rotatably with respect to the first shaft branch and has a contact portion that abuts the toilet seat behind the first shaft branch.
It is preferable that the toilet handrail device can be fixed to the toilet bowl by pressing the contact portion against a portion of the side surface of the toilet bowl that is higher than half the height of the toilet seat.

As a result, the rear downward force applied to the armrests and the backrest can be firmly received by the rear legs, and the toilet handrail device can be prevented from falling to the rear side. Further, by adopting a structure in which the rear leg is pressed against the side of the toilet bowl, the toilet handrail device can be fixed to the toilet bowl without moving in the left-right direction. If a structure that can maintain the horizontal angle of the rear legs is adopted, the toilet handrail device can be easily attached to the toilet bowl even after the toilet handrail device is once removed from the toilet bowl when cleaning the area around the toilet bowl. Will be possible.

In the toilet handrail device of the present invention,
A second lower rotating member that is attached to the first shaft branch in a horizontally rotatable state and has a third shaft branch at a position that is horizontally displaced forward or backward from the first shaft branch.
It shall be further provided with a second upper rotating member attached to the third shaft branch in a horizontally rotatable state.
It is also preferable that the second upper rotating member can be used as an armrest or a safety guard by horizontally rotating around the first shaft branch and the third shaft branch.

In the toilet handrail device of the present invention, it is also preferable that the armrest can be rotated up and down with respect to the backrest. This makes it possible to adjust the direction of the armrest in the vertical direction as well. Further, when the armrest is not required, the armrest can be retracted to a retracted position (for example, a position where the armrest faces substantially directly upward).

In this case, the vertical orientation of the armrest may be switched between one use position and one storage position, but it is also preferable to be able to adjust the use position in multiple stages or steplessly. .. This configuration can be realized, for example, by providing an angle adjusting mechanism provided with a lock spring at the base end of the armrest.

As described above, according to the present invention, it is possible to provide an armrest device for a toilet that has a high degree of freedom in adjusting the direction of the armrest and is easy to use in an appropriate state.

A preferred embodiment of the toilet handrail device of the present invention will be described more specifically with reference to the drawings. In the following, the toilet handrail device of the present invention will be described by taking two embodiments (first embodiment and second embodiment) as examples. However, the technical scope of the toilet handrail device of the present invention is not limited to these embodiments. The toilet handrail device of the present invention can be appropriately modified as long as the gist of the invention is not impaired.

1. 1. Toilet handrail device of the first embodiment First, the toilet handrail device of the first embodiment will be described. FIG. 1 is a diagram showing a state in which the toilet handrail device 10 of the first embodiment is assembled to a style toilet bowl 50. FIG. 1A shows a state in which the toilet handrail device 10 is viewed from above (plan view), and FIG. 1B shows a state in which the toilet handrail device 10 is viewed from the side (side view). Each is shown. As shown in FIG. 1, this toilet handrail device 10 is used by being assembled to a Western-style toilet bowl 50, and includes an integrated frame 11, a pair of left and right first lower rotating members 12, and left and right. It includes a pair of first upper rotating members 13, a pair of left and right second lower rotating members 19, and a pair of left and right upper rotating members 20.

As shown in FIG. 1A, the integrated frame 11 is formed by connecting a pair of left and right base members 11a with a connecting member 11b passing in front of the toilet bowl 50. The base member 11a functions as a leg portion for enhancing the installation stability of the toilet handrail device 10. In each of the base members 11A, the portion which becomes the front of the center C ₀ of the toilet seat 51, the first shaft support 11A ₁ are provided stands up upwardly. The first shaft _{support portion 11a 1} is formed of a hollow pipe member, and the upper end thereof is open. The connecting member 11b is formed so as to be curved along the front surface of the toilet bowl 50. The connecting member 11b is brought into contact with the toilet bowl at two points on the left and right (a pair of left and right contact portions 11b _1).

As shown in FIG. 1B, each of the first lower rotating members 12 is a member in which the lower shaft portion 12a and the upper shaft portion 12b are connected in a crank shape. In the toilet handrail device 10 of the first embodiment, one pipe member bent is used as each first lower rotating member 12. The outer diameter of the lower shaft portion 12a is _{set to be smaller than the inner diameter of the first shaft support portion 11a 1} , and the lower shaft portion 12a of the first lower rotating member 12 is inside _{the first shaft support portion 11a 1.} It is in a state where it is inserted and supported by the shaft. Therefore, each first lower-side rotary member 12, relative to the first shaft support 11A ₁ respectively in integrated frame 11, it has a horizontal rotatable state to the center line C ₁ Mawari. The upper shaft portion 12b of the first lower rotating member 12 is a portion that functions as a second shaft support portion to be described later.

As shown in FIG. 1A, each of the first upper rotating members 13 includes a front armrest 13a and a rear backrest 13b.

By providing the armrest 13a on the toilet handrail device 10, when standing and sitting on the toilet bowl 50, the armrest 13a can be grasped by hand or leaned against the armrest 13a, so that the person can easily stand and sit. become able to. Further, when sitting on the toilet bowl 50 and defecation, the elbow is placed on the armrest 13a and the upper body is tilted forward, so that it becomes easier to take a comfortable stool posture. Further, before defecation, it is possible to perform exercises that stimulate the internal organs, such as squatting while grasping the armrest 13a and twisting the waist. For this reason, not only is it easier to have a comfortable stool, but it is also possible to carry out preventive exercise for frailty syndrome.

In addition, by providing the backrest 13b on the toilet handrail device 10, the backrest 13b can support the vicinity of the waist of the person sitting on the toilet bowl 50 from behind. Therefore, the defecation posture can be further stabilized. In addition, it is possible to perform exercises that stimulate the internal organs, such as bending the upper body backward while the backrest 13b is resting on the waist. This exercise also leads to the prevention of comfortable stools and frailty.

In the toilet handrail device 10 of the first embodiment, the armrest 13a and the backrest 13b are integrally formed in a continuous form by bending one pipe member. As shown in FIG. 1A, the backrests 13b of each of the first upper rotating members 13 are curved so as to approach each other toward the rear end side.

A mounting shaft portion 13c is provided downward on the front end side of the first upper rotating member 13. The mounting shaft portion 13c is formed of a hollow pipe member, and the lower end thereof is open. The inner diameter of the mounting shaft portion 13c is set to be larger than the outer diameter of the upper shaft portion (second shaft branch) 12b of the first lower rotating member 12, and the mounting shaft 13c is set to the second shaft branch 12b. It is externally attached and supported by the shaft. Therefore, each of the first upper rotating members 13 is in a state of being horizontally rotatable around _{the center line C 2 with respect to the second shaft support portion 12b of each of the first lower rotating members 12.} ..

Thus, by the first upper turning member 13 and the horizontal rotatable structure to the first lower-side rotary member 12, the armrests 13a and back 13b, the horizontal rotating about the center line C ₂ Can be moved. Specifically, the position of the armrest 13b can be adjusted between the outer position laterally away from the toilet bowl 50 and the inner position closer to the toilet bowl 50. Similarly, the position of the backrest 13b can also be adjusted between the medial position of the toilet bowl 50 protruding rearward of the toilet seat and the lateral position of the toilet seat 50 from the rear to the side. In the toilet handrail device 10 of the first embodiment, since the armrest 13a and the backrest 13b are integrally provided, when the armrest 13a is moved, the backrest 13b also moves integrally.

As already mentioned, the armrests 13a and the backrest 13b have a function of supporting the body of the person sitting on the toilet bowl 50, a function of stabilizing the posture of the person sitting on the toilet bowl 50, promoting comfortable stools and preventing flare. Where there is a function to perform, by making the armrest 13a and the backrest 13b horizontally rotatable, the armrest 13a and the backrest 13b are used according to the usage mode and the physique of the user of the toilet handrail device 10. The positions (horizontal position) of the 13a and the backrest 13b can be adjusted. Further, although there is a type of the toilet bowl 50 provided with a toilet seat lid, when opening and closing the toilet seat lid, the backrest 13b can be retracted to a position (outer position) that does not interfere with the opening and closing of the toilet seat lid.

However, the armrest 13a and back 13b, only for horizontally rotating the center line C ₂ around, for example, to narrow the distance between the right and left armrests 13a, when moving the respective arm rest 13a inward position, The front end of the armrest 13a faces inward. Therefore, when the arm is turned in the front-rear direction, it becomes difficult to put the arm on the armrest 13a, and the usability of the armrest 13a and the backrest 13b is not always good.

In this respect, in the toilet handrail device 10 of the first embodiment, the first lower rotating member 12 that pivotally supports the first upper rotating member 13 provided with the armrest 13a and the backrest 13b in a horizontally rotatable state. itself, and it can be horizontally pivoted on the center line C ₁ around relative integral frame 11. In other words, the armrest 13a and the backrest 13b can rotate horizontally about each of _{the two horizontally displaced center lines (center line C 1} and center line C _2). Therefore, the orientation of the armrests 13 at each position from the outer position to the inner position can be adjusted in the horizontal direction, such as by turning the tip of the armrest 13 moved to the inner position forward. That is, the degree of freedom in adjusting the orientation of the armrest 13a and the backrest 13b is high, and the armrest 13 and the backrest 13b can be easily used in an appropriate state.

FIG. 2 is a view showing a state in which the left and right armrests 13a in the toilet handrail device 10 of the first embodiment are moved to the inner position while maintaining parallelism, as viewed from above. In the state shown in FIG. 2B, the left and right armrests 13 are moved inward from the state shown in FIG. 2A. In the toilet handrail device 10 of the first embodiment, as shown in FIG. 2, it is also possible to move the left and right armrests 13a to the inner position while maintaining parallelism. At this time, the distance between the left and right backrests 13b is also narrowed, but the orientation of the backrests 13b has not changed. This makes it possible to use the armrests 13a and the backrest 13b in a more appropriate orientation.

The height (vertical position) of the first upper rotating member 13 may be unchanged, but may be adjustable. This makes it possible to adjust the heights of the armrests 13a and the backrest 13b according to the physique and the like of the user of the toilet handrail device 10. In the toilet handrail device 10 of the first embodiment, as described above, the lower shaft portion 12a of the first lower rotating member 12 _{is inserted into the first shaft branch portion 11a 1} of the base member 11a, and the first A structure in which the mounting shaft portion 13c of the upper rotating member 13 is extrapolated to the upper shaft portion 12b (second shaft branch) of the first lower rotating member 12 is adopted, with respect to the first shaft branch 11a _1. The height of the first upper rotating member 13 can be adjusted by making the depth at which the lower shaft portion 12a is inserted and the depth at which the mounting shaft portion 13c is extrapolated with respect to the second shaft support portion 12b variable. become able to.

Further, in the toilet handrail device 10 of the first embodiment, as shown in FIG. 1, the first shaft branch portion 11a ₁ of the integrated frame 11 is connected to the second upper side via the second lower rotating member 19. A rotating member 20 is attached. As shown in FIG. 1B, the second lower rotating member 19 has an L-shape in a side view, has a lower shaft portion 19a on the lower end side thereof, and has an upper shaft portion 19a on the upper end side thereof. It has a part 19b. The upper shaft portion 19b of the second lower rotating member 19 is a portion that functions as a third shaft branch, which will be described later. Further, the second upper rotating member 20 has an inverted U shape in a side view, and has a rear shaft portion 20a on the rear end side. The horizontal portion of the second upper rotating member 20 can be used as a second handrail or a safety guard.

The lower shaft portion 19a of the second lower rotating member 19 is pivotally supported in a state of being horizontally rotatable with respect to _{the first shaft support portion 11a 1 of the integrated frame 11.} Further, the rear shaft portion 20a of the second upper rotating member 20 is pivotally supported in a state of being horizontally rotatable with respect to the upper shaft portion 19b (third shaft branch) of the second lower rotating member 19. There is. The upper shaft portion 19b (third shaft branch) is located at a position displaced in the horizontal direction with respect to _{the first shaft branch 11a 1.} Therefore, the second upper rotating member 20 (second handrail) is horizontally rotated around _{the first shaft branch 11a 1} (center line C ₁ ) and the third shaft branch 19b (center line C _4). You can do it.

In this way, the second upper rotating member 20 has a structure that allows horizontal rotation around _{two axes (first shaft branch 11a 1 and third shaft branch 19b).}
The second upper rotating member 20 can be positioned in front of the toilet bowl 50 and used as a safety guard. Further, when the safety guard is horizontally rotated outward, the safety guard can be used as an armrest or a handrail (second handrail).

By the way, when an excessive load is applied to the armrest 13a (first handrail) or the second upper rotating member 20 (second handrail) when standing or sitting, the rear side of the toilet handrail device 10 becomes the floor. Where there is a risk of lifting from the surface, in the toilet handrail device 10 of the first embodiment, as shown in FIG. 1B, the lower end of the bent portion (front side shaft portion 20b) of the second upper rotating member 20 is I try to touch the floor. Therefore, the load applied to the armrest 13a (first handrail) and the second upper rotating member 20 (second handrail) is firmly received so that the rear side of the toilet handrail device 10 does not rise. can do. For this reason, a large load can be applied to the armrest 13a not only when standing and sitting, but also when performing exercises to prevent constipation and frailty.

By the way, in the toilet handrail device 10 of the first embodiment, the first rotation regulating means 14 (FIG. 1 (b)) and the second rotation regulating means 15 (FIG. 1 (b)) are provided. .. By operating the first rotation regulating means 14 to prevent the lower shaft portion 12a of the first lower rotating member 12 from rotating with respect to the first _{shaft support portion 11a 1} of the integrated frame 11, the integral frame 11 is integrated. horizontal rotation of the first lower-side rotary member 12 (the center line C ₁ around the horizontal rotation) is adapted to be regulated relative to the frame 11. Further, the second rotation regulating means 15 is operated to prevent the mounting shaft portion 13c of the first upper rotating member 13 from rotating with respect to the second shaft support portion 12b of the first lower rotating member 12. it is, horizontal rotation of the first upper turning member 13 relative to the first lower-side rotary member 12 (the center line C ₂ around the horizontal rotation) is adapted to be regulated.

The structures of the first rotation regulating means 14 and the second rotation regulating means 15 are not particularly limited. In the toilet handrail device 10 of the first embodiment, all of them are tightening bolts to which a knob is attached to the base end side of the screw shaft. These tightening bolts have a screw shaft screwed onto an outer pipe member (first shaft support portion 11a ₁ in the first rotation regulating means 14 and mounting shaft portion 13c in the second rotation regulating means 15). When the knob is rotated in one direction, the tip of the screw shaft is an inner pipe member (lower shaft portion 12a in the first rotation regulating means 14 and second shaft branch 12b in the second rotation regulating means 15). The horizontal rotation is regulated by strongly pressing against the outer peripheral surface of the. On the contrary, when the knob is rotated to the other side, the tip of the screw shaft is separated from the outer peripheral surface of the inner pipe member, and horizontal rotation is allowed.

Further, in the toilet handrail device 10 of the first embodiment, as shown in FIG. 1, a pair of left and right rear legs 16 are provided behind the integrated frame 11. For this reason, the rear leg 16 firmly receives the rearward downward force applied to the armrest 13a and the backrest 13b so that the toilet handrail device 10 does not fall to the rear side.

FIG. 3A shows a perspective view of the integrated frame 11 and the rear leg 16, and FIG. 3B shows a side view of how they are assembled to the toilet bowl 50. The rear leg 16 is mounted in a horizontal rotatable state to the center line C ₃ around to the first shaft upper portion near the branch 11a ₁ of the left and right base member 11a. Therefore, the rear legs 16a can be arranged at appropriate positions according to the width of the toilet bowl 50, the left and right inner widths of the private toilet room, and the like. Further, when the toilet handrail device 10 is removed from the toilet bowl 50, the rear legs 16a can be folded so as not to get in the way. FIG. 4A shows a view of the integrated frame 11 and the rear leg 16 assembled to the toilet bowl 50 from above, and FIG. 4B shows a state in which the rear leg 16 is folded after being removed from the toilet bowl 50. The figure seen from above is shown.

A pressing operation means 17 is provided near the rotation center (front end) of each of the rear legs 16. The pressing operation means 17 is for horizontally rotating the rear leg 16 inward (the side approaching the toilet bowl 50) and pressing the rear leg 16 against the side of the toilet bowl 50. As a result, the toilet handrail device 10 can be fixed to the toilet bowl 50 in a state where it does not move in the left-right direction by the _{contact portion 11b 1 and the rear leg 16 provided on the connecting member 11b.} A contact portion 16a is provided on the horizontal portion of the rear leg 16. The contact portion 16a comes into contact with a portion (upper side surface of the toilet bowl 50) higher than half of the toilet seat height on the side surface of the toilet bowl 50, and the toilet handrail device 10 is in the width direction (left-right direction). It is less likely to wobble.

The specific structure of the pressing operation means 17 is not particularly limited as long as it can exhibit the above functions. In the toilet handrail device 10 of the first embodiment, as shown in FIG. 5, a tightening bolt having a knob attached to the base end side of the screw shaft is used as the pressing operation means 17. FIG. 5 is an enlarged cross-sectional view showing a state in which the periphery of the pressing operating means 17 in the toilet handrail device 10 is cut in a horizontal plane.

The screw shaft of the tightening bolt 17 (pressing operating means) is screwed to the fixing bracket 11c from the outside (the side opposite to the toilet bowl 50). The fixing bracket 11c is integrally fixed to the outer peripheral portion of the connecting member 11b in the base member 11a. This fixing bracket 11c, the rotary bracket 16b are rotatably supported by the center line C ₃ around a horizontal rotatable state. The front end of the rear leg 16 is integrally fixed to the rotating bracket 16b. When the knob of the tightening bolt 17 (pressing operation means) is rotated in one direction, the tip of the screw shaft of the tightening bolt 17 protrudes inward (to the side of the toilet bowl 50), and the contact portion of the rotating bracket 16b 16b ₁ abuts on, by pressing the contact portion 16b ₁ inwardly, so that the aft 16a is horizontal pivot inwardly.

By adopting the pressing operation means 17 having the above structure, the rear leg 16 can be held at an appropriate angle against the toilet bowl 50. Therefore, it goes without saying that the toilet handrail device 10 is firmly attached to the toilet bowl 50, and even when the toilet handrail device 10 is temporarily removed from the toilet bowl 50 when cleaning the periphery of the toilet bowl 50 or the like. If the tightening bolt 17 (pressing operation means) is held as it is at that time, when the toilet handrail device 10 is reassembled to the toilet bowl 50, the distance between the left and right rear legs 16a is in the original state ( The toilet handrail device 10 can be easily returned to the state before being removed from the toilet bowl 50).

2. The toilet handrail device of the second embodiment Next, the toilet handrail device of the second embodiment will be described. The toilet handrail device 10 of the second embodiment will be described focusing on a configuration different from that of the toilet handrail device 10 (FIG. 1) of the first embodiment described above, and the toilet handrail device of the first embodiment will be described. The explanation of the configuration common to No. 10 is omitted. As for the configuration not mentioned in the toilet handrail device 10 of the second embodiment, the same configuration as that described in the toilet handrail device 10 of the first embodiment can be adopted.

FIG. 6 shows a state in which the toilet handrail device 10 of the second embodiment is assembled to a Western-style toilet bowl 50, (a) a state viewed from above and (b) a state viewed from the side. It is a figure. In the toilet handrail device 10 (FIG. 1) of the first embodiment described above, the portion of the left and right first upper rotating members 13 from the armrest 13a to the backrest 13b is formed by one pipe member. The armrest 13a cannot be rotated up and down with respect to the backrest 13b. On the other hand, in the toilet handrail device 10 of the second embodiment, as shown in FIG. 6B, the armrest 13a is formed by a member different from the backrest 13b, but is integrated with the upper shaft portion 12b. It moves horizontally to enable parallel movement. Rear end portion of the armrest 13a, relative to other portions of the first upper turning member 13 is pivotally supported by the upper and lower rotatable state to the center line C ₅ around. The center line C ₅ is behind _{the center line C 1} of the horizontal rotation in the first shaft branch 11a _1.

As described above, in the toilet handrail device 10 of the second embodiment, the armrest 13a can be rotated up and down, and the physique of the user of the toilet handrail device 10 and the type of exercise performed by the user. The armrest 13a can be set at an appropriate vertical angle according to the above. Therefore, the above-mentioned frailty prevention effect and pleasant stool effect can be further enhanced. In addition, when the armrest 13a is not used, the armrest 13a can be turned upward (the armrest 13a is stored).

The vertical angle of the armrest 13a may be adjusted by using a latch mechanism or the like, but in the toilet handrail device 10 of the second embodiment, the vertical angle can be adjusted by using a lock spring mechanism. Specifically, it is integrally fixed to the mounting member (not shown) mounted in a stationary state with respect to the main body portion (part other than the armrest portion 13a) of the first upper rotating member 13. A lock drum (not shown), a tubular wall portion (not shown) formed on the armrest 13a so as to be arranged on the same axis as the lock drum, and a coil externally fitted to the lock drum and the tubular wall portion. A lock spring mechanism including a lock spring made of a spring (not shown) and a cam mechanism (not shown) for operating the free end of the lock spring is adopted. This lock spring mechanism is the same as that adopted in the "height-adjustable armrest" described in Japanese Patent No. 6685527. This makes it possible to adjust the height of the armrest 13a steplessly.

3. 3. Others In each of the toilet handrail devices 10 of the first embodiment and the second embodiment described above, the first lower rotating member 12 is horizontally rotated around the _{center line C 1 and the first upper rotating member 12 is rotated.} The horizontal rotation around the center line C ₂ of the member 13 was independent, but by adopting a parallel link mechanism, etc., _{the horizontal rotation around the center line C 1 and} the horizontal rotation around the center line C ₂ May be linked. As a result, the left and right armrests 13a can be translated between the outer position and the inner position while the left and right armrests 13a are always kept parallel.
