The universal attachment 36 comprises a disk-shaped main body 36a attached to the adjuster 35 via a universal joint, and a resin layer 36b and a resilient layer 36c sequentially laminated on the surface of the main body 36a. As shown by a dashed line in FIG. 5, the main body 36a can adjust the contact angle with a certain degree of freedom in accordance with the curved state of the upper outer surface b of the toilet A.

The front and rear ends of the base portion 11 of the upright member 10, the rear end of the movable portion 25 of the U-shaped member 21, and the connection portion 27 of the main body portion 28 of the straight member 26
Adjusters 10a and 20a for height adjustment are attached to the lower surfaces, respectively. Even when the toilet floor is inclined in consideration of drainage or the like, the adjusters 10a and 20a are used to adjust the height. Since the height can be adjusted appropriately, it is possible to eliminate rattling of the handrail 1 for the toilet bowl to be installed.

The toilet handrail 1 configured as described above is
To attach to the existing toilet bowl A, first, the connecting rod 29
After the U is removed, the U-shaped member 21 is fitted into the floor fixing portion a from the front side of the toilet A, and the removed connecting rod 29 is attached again. In addition, at this time, the movable part 25 depends on the size and shape of the floor fixing part a of the toilet A to be attached.
Adjust the mounting position of.

Next, while observing the shape of the curved upper outer surface b of the toilet A, the straight member 2 is positioned at the most suitable position.
6 after fixing, the upper arm 33 of the fixed arm 31
Is pulled up from the lower arm 32, and the upper arm 33 is fixed with the free attachment 36 in contact with the upper outer surface b. When the adjustable attachment 36 is further protruded by the adjuster 35, and the curved upper outer surfaces b on the right and left sides of the toilet A are pressed obliquely from below by the adjustable attachment 36, the toilet handrail 1 is securely connected to the toilet A. Fixed to

At this time, the pressing posture of the universal attachment 36 naturally changes so as to be along the curved upper outer surface b of the toilet A, and the pressing surface of the universal attachment 36 contacts the curved upper outer surface b of the toilet A. Make sure they adhere. Also,
When the curved upper outer surface b of the toilet A is pressed by the universal attachment 36, the rear end of the linear portion 23 of the U-shaped member 21, that is, the movable portion 25 tends to spread outward by the reaction force. Since the connecting rod 29 is prevented by the presence of the connecting rod 29, the pressing force of the universal attachment 36 is reliably applied to the toilet A without weakening.

Finally, when the fixed position of the upper column 14 is adjusted in order to adjust the height of the handrail 16 in accordance with the height of the elderly using the handrail 1 for toilet, the handrail for toilet is used. 1 is completed.

As described above, in the toilet handrail 1, the connecting member 20 for connecting the upright members 10 to each other is connected to the U-shaped member 2.
1 and the straight member 26, and the upright member 10 and the U-shaped member 21 are connected by the straight member 26 at the central portion in the front-rear direction of the toilet A,
In other words, by bending the connecting member 20 that crosses the front of the floor fixing portion a of the toilet A, the outer portion of the floor fixing portion a of the connecting member 20 is retracted to near the center of the toilet A in the front-rear direction. As a result, there is no obstacle around the front side of the floor fixing part a of the toilet A, and as shown in FIG. 6, when an elderly man with weak legs tries to get up from the toilet and moves one of the feet backward. But U-shaped member 21
Since the moving area is sufficiently secured between the and the upright member 10, an elderly man with weak legs can stand up from the toilet A smoothly.

Considering only the rising motion of the elderly with weak legs, it is conceivable to dispose the connecting member 20 only on the rear side of the toilet A to release the front peripheral portion of the floor fixing portion a of the toilet A. However, when such a configuration is employed, there is a problem in that the strength of the front portion of the toilet handrail, which mainly exerts force, is reduced. In contrast, in the above-mentioned toilet handrail 1, since the connecting member 20 is disposed at the front portion where the force is applied, there is no problem in strength, and moreover, the handrail 1 can be used for a standing operation performed by an elderly man with weak legs. Can cope well.

Also, as shown in FIG. 7, by pulling up and fixing one of the left and right upper supports 14, the handrail portion 16 can be held at a considerably high position. It can also be used as a handrail. When standing in front of the toilet A in order to urinate, the standing position differs depending on the person. However, even in the case of a person standing very close to the toilet A, the straight member 26 may be used.
Has receded to the vicinity of the center of the toilet A, so that the straight member 26 does not become an obstacle, and the foot can enter between the U-shaped member 21 and the upright member 10.

Further, as described above, the curved upper outer surfaces b on the right and left sides of the toilet A are respectively pressed obliquely from below by the fixed arm 31, so that positional deviation and rattling in the left and right direction are prevented. In addition to being blocked, the reaction force causes the toilet handrail 1 itself to be pressed against the floor surface of the toilet, so that even if a force is applied to the handrail portion 16 located on the front side, the toilet handrail 1 can be kept behind the toilet handrail 1. The end is not lifted, and a stable installation state is ensured.

Further, the shape of the curved upper outer surface b of the toilet A does not greatly differ depending on the manufacturer and the type of the toilet, and is generally constant.
There is almost no need to change the pressing position depending on the type of toilet bowl to be attached, and such a position adjustment operation can be omitted. Therefore, there is also an effect that the fixing operation can be performed easily and reliably compared to the conventional toilet handrail 60 in which the side surfaces of the floor fixing portion a, whose shapes differ greatly depending on the manufacturer and the type of the toilet, are horizontally pressed from the left and right sides.

The attachment 3 is attached to the pressing portion 34.
6, the pressing posture of the universal attachment 36 changes according to the curved shape of the upper outer surface b of the toilet A to be attached, and the universal attachment 36 is always brought into substantially surface contact with the upper outer surface b of the toilet A. Can do it, and
Elastic layer 36 provided on the surface of universal attachment 36
Due to the presence of c, it is possible to press in a more closely contacted state, and there is also an effect that a stable fixed state can be obtained.

The upper support 14 to which the handrail 16 is attached can be easily removed from the lower support 13 by removing the knob bolt 15 and pulling it out, so that the transfer from the wheelchair to the toilet A can be easily performed. be able to.

As shown in FIGS. 1 and 3, the toilet A
The upright member 10 standing upright is disposed from the center of the toilet A to the front side, and a space without obstacles is formed on both rear sides of the toilet A, so that a cleaning tool is placed, etc. The space can be used freely, and a narrow toilet can be used effectively.

The handrail 16 is also provided on the base 11
, And is located on the front side from the center of the toilet A in the same manner as the base 11, so that a large space is secured in the rear part of the toilet A. Even in the case of a functional toilet attached to the side, the handrail 1
The handrail 6 does not hinder the operation of the operation unit 6 even when the buttocks are wiped after the stool.

In the embodiment described above, the fixed arm 31 is fixed to the straight member 26 at a predetermined rising angle. For example, as shown in FIG. The adjustment member 41 is movably mounted, and has an arc-shaped adjustment hole 41
Is attached, and the thumbscrew 42 passed through the adjustment hole 41 is screwed into a nut (not shown) fixed to the lower arm 32 and tightened.
The lower arm 32 can be fixed at an arbitrary rising angle within the range of (1). By adopting such a configuration, there is an effect that it can be attached to a toilet having a unique shape different from a general toilet.

In the above-described embodiment, the linear portion 23 of the U-shaped member 21 constituting the connecting member 20 is extended to the rear of the toilet A to secure the support stability of the entire toilet handrail 1. However, the present invention is not limited to such a form. For example, as shown in FIG. 9, by extending the base 11 of the upright member 10 to the rear of the toilet A, the support of the toilet handrail itself is supported. Stability can be ensured, and the length of the straight portion 23 of the U-shaped member 21 can be reduced. However, when such a form is adopted, the rear end of the base 11 may be opened outward by fixing to the toilet A by the fixing member 30. It is desirable to connect them to each other by connecting rods 29.

Further, in the above-described embodiment, the handrail portion 16 is held by one post 12, but as shown in FIG. 10, a rectangular frame having two front and rear posts 12a and 12b is used. It is also possible to configure the upright member 10. In addition, when such a form is adopted,
Each of the columns 12a and 12b needs to be able to expand and contract vertically.

The upright member 10 can secure a certain degree of upright stability if the base portion 11 extends to some extent before and after the support column 12, so that, for example, as shown in FIG. And the straight member 26 is fixed to the center of the base 11 in the front-rear direction, and the straight member 26 is fixed to the center of the base 11 in the front-rear direction. Can be retracted to the rear of the toilet A. In this way, by retracting the standing member 10, the front peripheral portion of the floor fixing portion a of the toilet A is further released, so that one of the feet is moved rearward from the toilet posture to stand up. Considering the rising motion of an elderly person with weak legs, it can be said that this is a more preferable form.

Further, in each of the above embodiments, a configuration in which a plurality of members are fixed by knob bolts to assemble one toilet handrail is adopted. It is also possible to adopt a configuration in which the members are integrally fixed by welding or the like, except for the necessary movable parts.

In each of the above-described embodiments, the knob bolt 15 passed through the elongated hole 13a formed in the lower column 13 is screwed into a screw hole formed in the upper column 14 to be tightened. 14 is fixed at an arbitrary height.
It is also possible to provide a ratchet mechanism or the like in 2 and to gradually hold the upper support 14 at an arbitrary height position only by pulling it upward.

In each of the above embodiments, the upright member 1
Although the members such as the connecting member 20 and the fixing member 30 are mainly formed of a metal material, they may be formed of a resin material such as reinforced plastic or wood.

[0050]

As described above, the handrail for a toilet according to the present invention is characterized in that the connecting member for connecting the upright member to each other in the left-right direction at the lower front side of the toilet is bent outside the floor fixing portion of the toilet. Because the part is retracted to the vicinity of the central part in the front-rear direction of the toilet and the front peripheral part of the floor fixing part is released, the connecting member performs when the elderly with weak legs rises from the toilet posture. There is an effect that an elderly man with weak legs can smoothly stand up from the toilet without obstructing the rising motion of moving one leg backward.
