Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a standing handrail which is attached to an inner wall surface of a toilet, a bathroom, an entrance or the like to assist a standing / standing operation.

[0002]

2. Description of the Related Art Conventionally, as a standing and sitting handrail used for a toilet, for example, as shown in FIG. 7, there is an I-shaped handrail having a vertical grip portion (1) extending in a vertical direction. Further, as shown in FIG. 8, there is also an L-shaped handrail in which a vertical bar-shaped grip portion (2) extending in the vertical direction and a horizontal bar-shaped grip portion (3) extending in the horizontal direction are connected.

[0003]

Generally, when a person sits on a toilet or rises from a sitting state, the center of gravity moves in the front-rear direction and the height direction. In order to support the body by gripping the vertical grip of the handrail in this standing and sitting motion, it is necessary to pull the vertical grip downward and backward, that is, in an oblique direction.

[0004] When a handrail is used, the position of the hand does not change. Therefore, the positional relationship between the shoulder that moves with the movement of the center of gravity and the hand that does not move differs between a standing state and a sitting state. . That is, when standing up, the shoulders and hands are positioned above and below each other, and when sitting, the shoulders and hands are positioned back and forth from each other.

In the conventional I-type or L-type handrail, the vertical grips (1) and (2) are arranged in the vertical direction, so that it is difficult to pull diagonally and apply a force. Also, when you hold the vertical grips (1) and (2) and sit on the toilet,
As shown in FIG. 9, there is almost no wrist bending, but when the user grips the vertical grips (1) and (2) and stands up,
As shown in FIG. 10, the wrist bends greatly to the thumb side, resulting in a very cramped posture, and thus the wrist is easily burdened and difficult to use.

SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to provide a standing and sitting handrail which is easy to apply force when standing and sitting and can reduce the burden on the wrist.

[0007]

In order to solve the above-mentioned problems, a standing and sitting handrail according to the present invention is characterized in that a vertically extending rod-shaped vertical grip is formed at an angle of 10 ° in front of a user with respect to a vertical line. It is characterized by being tilted within a range of 25 °.

[0008] A bar-shaped vertical grip portion extending in the vertical direction;
A horizontal grip portion extending laterally from the vertical grip portion, wherein the vertical grip portion is positioned at a distance of 1
It is characterized by being inclined within the range of 0 ° to 25 °.

[0009] Furthermore, a bar-shaped vertical grip portion extending in the vertical direction and a horizontal grip portion extending laterally from the vertical grip portion are provided, and the angle between the vertical grip portion and the horizontal grip portion is from 100 ° to 1 °.
When set within a range of 15 ° and the horizontal grip portion is mounted in a horizontal state, the vertical grip portion is in a range of 10 ° to 25 ° forward with respect to a vertical line as viewed from a user. It is characterized by being inclined at.

The diameter is set within a range of 28 mm to 34 mm for easy grip.

Next, the arrangement of the standing handrail will be described. According to an experiment conducted on the elderly by the applicant, when such a standing handrail is placed on a Western-style toilet, the grip position is 800 mm above the floor surface.
In the range of 10 mm to 1000 mm, and 10
It has been found that if the angle is in the range of ゜ to 25 °, the force is easily applied and the burden on the wrist is small.

Therefore, based on the results of this experiment, the standing and sitting handrail (10) is designed so that the vertical grip (16) is at least in the proper grip position, and the vertical grip is provided.
(16) is tilted forward from the person sitting on the toilet (11) with respect to the vertical line within a range of 10 to 25 degrees, and the inner wall (1) is tilted.
It is attached to 2).

FIG. 3 shows a state in which the standing handrail (10) is used to sit on the toilet (11) or stand up from the sitting state. In the drawing, the solid line indicates the state of the arm when sitting down, and the two-dot chain line indicates the state of the arm when standing up. In the standing and sitting handrail (10), the inclination angle (θ1) of the vertical grip portion (16) with respect to the vertical line is set to 1
Since it is set within the range of 0 ゜ to 25 ゜, the vertical grip
(16) is easy to pull downward and backward, and it is easy to apply force.

Further, with regard to bending of the wrist, the wrist bends slightly to the little finger side in a sitting state, so that the burden on the wrist can be reduced without forcing a cramped posture.

Even if the vertical grip is inclined forward, the inclination angle is large (for example, about 30 ° to 45 °).
At times, the direction of the vertical grip approaches the direction in which force is applied, and the hand becomes slippery when pulled. Also, regarding the bending of the wrist, the wrist bends greatly toward the little finger when sitting down, and the burden on the wrist increases. Therefore, it is desirable to keep the inclination angle (θ1) to 25 °.
