Cane for the visually impaired {STICK FOR THE BLIND}

The present invention relates to a cane for the visually impaired. More particularly, the present invention relates to a cane for the visually impaired, which can protect the wrist of the visually impaired without using a separate power or power source.

In general, blind people often use canes to go to the desired place or follow a guide dog. In this case, the visually impaired person was forced to hit the cane, predict the situation, and walk or guide the dog. If you use a cane, it is difficult to make accurate judgments about road conditions, which may expose you to many risks, and may lead to carpal overuse syndrome or degenerative diseases. It was difficult and costly to manage and care for guide dogs.

In recent years, it is being advanced and developed in connection with the high-tech industry, such as the development of a cane for the visually impaired using ultrasonic waves or Bluetooth. However, considering the economic aspect, these canes are difficult to realize because they are expensive to install high-tech equipment.

Provides the effect of maintaining position.

Hereinafter, an embodiment of a cane for the visually impaired according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a cane for the visually impaired according to the present invention. Referring to FIG. 1, the cane for the visually impaired according to the present invention includes a lower body 10, an upper body 20, and a handle 30.

The lower body 10 and the upper body 20 are configured to combine with each other to form a cane body, the lower body 10 and the upper body 20 is elastically coupled to each other in the 'A' portion. The lower end of the lower body 10 is provided with a wheel portion 12, the wheel portion 12 is preferably coupled to rotate 360 ° with respect to the lower body (10). The wheel part 12 may be formed to be rotatable 360 ° by a structure formed by installing a steel ball, such as a caster structure or a tip of a ballpoint pen. In addition, the wheel part 12 is provided with an LED (not shown) that can emit light by itself (for example, by using the power of rotation of the wheel part), so that a third party can see from the light of the LED even when there is no ambient light at night. It is desirable to be able to easily identify the disabled.

As such, the cane for the visually impaired according to the present invention is provided with the wheel part 12, thereby eliminating the process for the visually impaired person who needs the conventional stick-shaped cane to keep track of the ground. Instead, the visually impaired person can check the ground situation while walking while pushing the wand against the wheel part 12.

The upper end of the upper body 20 is provided with a handle 30 inclined at an angle with respect to the upper body 20. The handle portion 30 may be integrally formed with the upper body 20 as shown in FIG. 1, or may be formed so that the inclination angle with respect to the upper body 20 can be adjusted as described later (FIG. 3). . It is preferable that a plurality of irregularities 36 are formed on the outer circumferential surface of the handle part 30 so that the visually impaired person easily grips the hand and the handle part 30 does not slip from the hand of the visually impaired person.

Looking at the reason why the handle 30 is configured to be inclined with respect to the upper body 20, there is a normal position (normal position) on the wrist of the human body. This refers to a posture where the wrist is most comfortable and the load on the wrist is lightest, for example when a person is standing with a cane or the like. In order to maintain the normal position of the wrist, there should be no front, rear, left and right inclination of the cane, but the conventional wheeled cane is inclined to the wrist of a visually impaired person to make the wheel touch the ground. At this time, the nerves of the human body pass along the inclined direction of the wrist, and the nerves dominate the muscles that rotate the wrist, and thus are easily damaged when excessive tension is applied. Therefore, the handle 30 is inclined as described above, so that the visually impaired person can walk while holding the cane while maintaining the normal position of the wrist.

Most preferably, the handle has an angle of inclination (α; see FIG. 1) with respect to the upper body of 40 ° to 50 °. In this case, assuming that the handle portion 30 is maintained parallel to the ground, the cane body (10, 20) is to maintain an angle of 40 ° to 50 ° with respect to the ground. This is to minimize the tension on the wrist when holding the cane. If the inclination angle is less than 40 °, the ulnar deviation of the wrist (although less than the straight cane) is in the direction of the little finger. This is because it is difficult to maintain the wrist's normal position because bending may occur, and a radial deviation may occur at 50 ° or more.

Next, FIG. 2 is an enlarged cross-sectional view of part A of FIG. 1. Referring to Figure 2, the lower end of the upper body 20 of the cane for the blind according to the present invention is provided with an elastic member 22. And the hollow part 24 for accommodating the elastic member 22 is formed in the upper body 20. The lower end of the upper body 20, that is, the opening of the hollow portion 24 is formed with a stepped protrusion 26 protruding a predetermined length toward the circumferential center direction.

And the upper end of the lower body 10 is formed with a protrusion 14 in a shape protruding in a predetermined length in the radial direction, the upper end of the lower body 10 including the protrusion 14 is the hollow portion of the upper body 20 ( It is inserted into and positioned in the 24, and is provided while contacting the elastic member 22 in the hollow portion 24. As a result, the lower body 10 and the upper body 20 are elastically coupled to each other by the elastic force of the elastic member 22.

That is, even if an external force or an impact is applied through the wheel 12 of the lower body 10, the external force is not directly transmitted to the wrist or arm of the visually impaired, but is absorbed by the elastic member 22, thereby the wrist and arm of the visually impaired. Will protect. This is to compensate for the disadvantage that can occur by having the cane for the blind according to the present invention having a wheel portion (12). That is, when the cane hits an obstacle when the cane is pushed to the ground using the wheel part 12, the shock can be transmitted to the wrist and arm of the visually impaired without filtration.

3 is an enlarged perspective view of part 'B' in FIG. 1. Referring to FIG. 3, the upper body 20 and the handle 30 are provided to be rotatable to each other by the hinge 32, that is, to adjust angles inclined to each other. The angle formed by the upper body 20 and the handle 30 may be different depending on the height (key) of the visually impaired within a predetermined range. In order to adjust the proper angle, the preferred embodiment of the present invention includes a hinge 32 to adjust the inclination angle.

When the blind person uses the cane after adjusting the inclination angle appropriately, it is necessary to fix the inclination angle between the upper body 20 and the handle 30 so as not to be adjusted. Referring to FIG. 4, which is a sectional view along the C-C part of FIG. 3, a fixing member 34 capable of fixing the hinge 32 is provided at one end of the hinge 32 to adjust the inclination angle. The fixing member 34 has a thread-like structure, so that the user can easily fix or release the hinge 32 by holding and holding the fixing member 34.

As described above, the cane for the visually impaired of the present invention protects the wrist by minimizing the shock transmitted to the wrist of the visually impaired, to make it easy to check the location of the visually impaired to others, and the wrist of the visually impaired when using the cane. This tilting can be prevented to provide the effect of maintaining the normal position.

The present invention is not limited to the embodiments described, it can be obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention, such modifications or modifications are present invention It belongs to the utility model claim of the.
