Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cane having three legs, dispersing the load, improving walking stability, and attaching a cushion to the cane to make the staff feel lighter than the weight of the cane when used. The present invention relates to a cushion-type three-legged cane capable of reducing fatigue.

[0002]

2. Description of the Related Art The elderly and those who have low back pain walk on a walking stick. Recently, a four-point stick or a single stick with a spring attached thereto, or a simple single stick without attachment has been used. Although one stick is common, the emphasis is not on stability but on ease of use. The four-point cane has good stability but is inconvenient and heavy, and is not suitable for indoor use for a long time. Both are canes that have both strengths and weaknesses.

Therefore, a cane in which a spring is combined with a cane has been devised (Japanese Patent Laid-Open No. 9-201216) and Japanese Patent Laid-Open No. Hei 10-313921, but neither can satisfy walking stability. Although the supporting cane and the four-point cane are excellent in stability, they have difficulty in use.

[0004]

The walking stick is indispensable especially for the elderly and the backache, but the range of use depends on the physical strength of the individual and the degree of disability. At present, there is no existing cane which has both fatigue reduction and walking stability, and it is difficult for a user to select the cane, so that it is difficult to find a suitable cane. Also, one cane cannot stand alone, so you must always carry it or lean against it. The present invention solves these problems, and provides a cushion-type three-legged cane that can be used for a long time and that can be made to have a feeling of walking stability and lighter than the weight of the cane.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to FIGS. This three-piece cushion type cane is a forefoot cushion type, a grip part position change type,
It can be broadly divided into three types of main cushion type.

FIG. 1 shows a cushion type three-legged cane according to the present invention. The cane main body is divided into the cane main body upper part (1) and the cane main body lower part (2), and the connecting part (16) is inserted into the through hole using a spring stopper pin, the height is determined, and the connecting part rubber cover (5) Is provided to prevent displacement.

A bent portion b (17) is provided in the upper portion of the cane body (1) at an appropriate angle with respect to the human wand, and the angle of the grip portion (3) is provided by bending the bent portion a (4). . A grip at the tip that emphasizes lightness and grip (3)
Is fixed.

The lower part (2) of the cane main body is divided into three parts, and three feet are provided. This is in consideration of the balance and ease of use of the whole cane because the three points are optimal for stability. For the purpose of cushioning the shock when wearing a cane,
A slide cushion rubber (9) is provided at the tip of the rear foot with a rear foot cushion rubber (11).

FIGS. 2A and 2B show a cushion portion of the forefoot (6). FIG. 2A is a side view, and FIG.
It is a sectional view of a part. The forefoot (6) has a through hole, and a spring stopper pin (14) is fixedly provided as a stopper. In the forefoot (6), a coil spring (1
3) The slide bar (7) is stored. The slide bar (7) is provided with a slide groove (15) and slides along a slide bar stopper pin (12). The stroke is set by the length of the slide groove (15). To protect the slide bar stopper pin (12), a slide bar stopper pin rubber cover (8) is provided.

FIG. 3 is a sectional view of FIG. 1A-A showing that the coil spring has been compressed. The coil spring (13) housed in the forefoot (6) is compressed and slides (7).
Slides along the slide rod stopper pin (12) in the slide groove (15) and stops at the retracted end of the slide groove (15).

FIG. 4 shows a three-foot cushion type. (A) is a side view, and (b) is a front view, in which the cushion shown in FIGS. 2 and 3 is provided on all three feet. The use of uneven places and the mitigation of shock can be obtained.

FIG. 5 shows a configuration in which the tip from the bent portion a (4) is eliminated, and the grip portion (3) is fixedly provided between the bent portion a (4) and the bent portion b (17). The waist is adapted to a severely bent person and can be replaced with the cane body upper part (1) of FIG.

[0017] If the use of both hands while using this cane, it can be made to stand on the spot, so that you do not hold the cane or lean on your own body or wall, and fall over That is, the picking-up operation is reduced.

[0018]

According to the present invention, the feeling of stability of the cane supporting the body with the sense of stability of the three legs and the repulsive force of the cushion reduce the fatigue burden on the user and enable long-term use. Also, by using the grip in the opposite direction and using it, the feeling of anxiety on a downhill can be reduced. Furthermore, since the cane body does not lean or lean, it is easy to use.
