Abstract

PURPOSE:To obtain a sitting stick facilitating the standing up by using one leg bonded to a rotatable body and forked legs bonded to form a fork in its top laterally horizontal direction. CONSTITUTION:A hollow sitting stick body 1 having nearly an equal length and concentrically formed on the outside of a circular pipe 1 has a central large diameter part 2a, heading for both the ends, middle diameter step parts 2b, 2b, small diameter step parts 2c, 2c, and screw parts 2d, 2d having a diameter smaller than that of the small diameter step parts 2c, 2c, and a cap 5 with an inner screw 5a corresponding to the outer screw part 2d rotatably holds a rotatable body 3 to the body 1 by being spirally fastened to the outer screw part 2d. A leg 6 for holding a sitting stick at a determined height is bonded to each rotatable body 3 lower surface with an inclination toward the cap 5 side. Thus, when a person changes sitting posture to standing posture, both hands are put on the sitting stick body, the arms are stood, whereby the body (hip part) can easily be brought up.

Description

[Detailed Description of the Invention] Industrial Application Fields The present invention provides a crutch that is used by people who have lost the ability to stand and walk or who have weak walking ability to lift their bodies, stand up, or move around. It is something that takes place in between.

<Conventional technology> Conventionally, when a person who is able to walk but has difficulty standing up moves from a sitting position to a standing position, he or she places an object, such as a desk, in his or her hands, raises his arms, and lifts his body (buttocks). There is. However, since it is not possible to freely adjust the height of desks, etc. by +114vJ, it has been pointed out that some people find it too high or too low, making it difficult to stand up.

<Problems to be Solved by the Invention> For the reasons described above, there is a need for a sitting cane that allows the user to easily stand up.

The object of the present invention is to provide a seat cane that solves the above problems.

<Means for Solving the Problems> In order to achieve the above object, the seat cane according to the present invention has a large diameter part in the center and a middle part on both sides of the horizontal hollow metal circular tube. A hollow seating material body of approximately equal length formed by concentrically forming a diameter stepped portion, a small diameter stepped portion, and a screw portion smaller in diameter than the small diameter stepped portion is fitted, and each medium diameter stepped portion and small diameter stepped portion of the seat material body are fitted. A rotatable body is fitted on the outside of the seat, an internally threaded cap is fastened to each externally threaded part, and legs for holding the seat material at a predetermined height are connected to the lower surface of each rotatable body.

When the seat cane constructed as described above is placed on a complex surface with slight differences in height, the posture of the legs will be different from when placed on a horizontal surface, but the posture of the legs will be different from when placed on a horizontal surface, but the posture of the legs will be different from when placed on a horizontal surface. When you put your weight on it, the rotatable body can rotate freely according to the change in the posture of the leg, and in the most stable state, it can rotate and hold the crutch stably. . Therefore, when changing from a sitting position to a standing position, the user can easily remove winter hair from the seat material body, raise his arms, and lift his body (buttocks).

<Example> To explain the example with reference to the drawings, 1 is a horizontal hollow metal circular tube, and 2 is a hollow seat body of approximately equal length formed concentrically on the outside of the circular tube 1. There, the central large diameter portion 2a
, medium-diameter stepped portions 2b, 2b, toward both sides thereof, respectively.
Small diameter stepped portions 2c, 2c, the small diameter step H2e + '2 c
A threaded portion 2 (l 2c) having a smaller diameter is formed. 3 is a rotatable body fitted over the outside of each medium diameter stepped portion 2b and small diameter stepped portion 2c of the seat main body 1, and A bending loop-shaped plate spring 4 is interposed between the large diameter hole 3a formed by enlarging and the small diameter stepped portion 2c. 5 is a cap with an internal thread 5a corresponding to the external thread portion 2c. , external screw 1B
2c, the rotatable body 3 is rotatably held in the main body 1.

Legs 6 for holding the cane at a predetermined height are connected to the lower surface of each rotatable body 3 and are inclined toward the cap 5@. Various structures are conceivable for this leg 6.

For example, as shown in FIG.
The cane is supported by four legs at the front and back, like a horse. The second example, as shown in FIG. 5, consists of a single piece 116b connected to the rotatable body 3 and a bifurcated tip *6C that is coupled to form a bifurcated portion in the left and right horizontal directions.

Note that a ring-shaped seal fi is provided on the mutually abutting end surfaces of the central large diameter portion 2a of the seat main body 1, the rotatable body 3, and the cap 5.
A sealing O-ring 8 is formed in the groove 7.
Charge.

Next, the effect will be explained. If you place the seat material on a surface that is not horizontal but has a complex surface with slight height differences (for example, on top of the tatami legs and cushions, on uneven ground outdoors, etc.), put your arms upright, and put your weight on it, it will cause illumination. .

In the example, the posture of the leg 6 changes in accordance with the tip of the leg 5a, and in the second example, the contact surface of the leg 1116c. As the posture of l16 changes, the rotatable body 3 can freely rotate, and can rotate to the most stable state and hold the cane stably. Therefore, when a person who is able to walk but has difficulty standing up moves from a sitting position to a standing position, there are two
By placing the left and right winter coats on each 1-liter seat material body, you can easily raise your body (buttocks) by raising your arms.

In addition, a person who has difficulty walking places a winter coat on the pair of seat members 1.1 (grasping each seat cane), stands up both arms, holds the body (kidneys and liver), and lifts the raised step. By repeating the actions of swinging the seat 1.1 towards 117 (or backwards), then bending both arms, lowering the buttocks to the floor, and then shifting the seat body 1.1 towards the front (or @), You can move forward (or backward) very easily.

Note that the gap rl between the rotatable body ;) and the small diameter stepped portion 2c: the rotatable body 3 is
Since it does not rotate unless you apply a strong force, when you put your arms on the cane and put your weight on it, the cane remains stable and does not wobble.

Further, each abutting surface is watertightly sealed by an O-ring 8, and can be washed with water, so that it can be used underwater, such as in a bath, if necessary.

<Effects of the Invention> Since the present invention is configured as described above, a physically handicapped person can easily sit in a place consisting of complex shapes with height differences (for example, both sides of a cushion and a tatami surface, outdoors). It is extremely convenient to use when standing up or moving on uneven ground, etc., as it has increased stability and a wider range of application than conventional ones.
