Description

[Detailed Description of the Invention] The present invention relates to a cane that can safely and reliably assist a blind person in walking.

The blind person's cane that is commonly used consists of a stick.
I was walking while checking the safety of the walking surface by touching the tip of several points on the walking surface (road) one after another.

However, there were frequent accidents in which blind people using such canes would fall down the station stairs or fall from the platform onto the tracks.

This was due to the inability to continuously check the safety of the walking surface.

Therefore, in order to prevent the above-mentioned dangers, the present invention provides an extremely simple cane for blind people that allows continuous confirmation of the safety of the walking surface.

Embodiments of the present invention will be described below based on the drawings.

As shown in Figs. 1 and 2, the blind person's cane (hereinafter referred to as a tree branch) of the present invention has two protrusions at the lower end of a cane-like cane body 1 that protrude in a direction different from the axial direction of the cane body 1. A support member 7 is attached.

A convex detection rod 4 which also serves as an axle is horizontally suspended between the image front ends of the bifurcated support member 7, and wheels 2 and 3 are mounted on both ends of the detection rod 4.
be installed so that it can rotate freely.

The distance between the wheels is approximately equal to the distance 1 between the widthwise centers of the legs 9.10 (see FIG. 3) of the blind person 8 in the standing state or the distance 1' between the wheels of the blind person 8.

Further, a sharp metal cap is fitted to the lower end of the cane body 1, and forms an escape prevention member 6.

Note that the tip of the member does not necessarily have to be sharp, and may be a flat surface located slightly above the lower surfaces of the wheels 2 and 3.

Further, FIG. 3 is a plan view showing a second embodiment of the tree branch.

In the same embodiment, the cane body 1 and the convex detection rod 4 which also serves as the axle are L
Connected to glyphs.

Further, the convex detection rod is made of a wire made of spring steel, and a coiled portion 11 is formed at the corner of the above-mentioned letter shape, and the rear end thereof is connected to the cane main body 1, and the detection rod 4 itself is made of a wire rod made of spring steel. It also serves as the support member 7.

Next, the effect of tree branches will be explained.

First of all, in the canes shown in Figures 1 and 2, the blind person should use the handle 5 of the cane.
Grip it, position it in the center of your body, and turn the wheel 2,
3 is grounded.

A blind person can simply walk while holding a cane.

If there is a raised sidewalk curb on the walking surface,
Since the wheels of the tree branch stop at the rising corner, the blind person can immediately perceive the curb and accurately measure its position.

At the same time, the height of the tree branch can be perceived by lifting the tip of the tree branch along the vertical surface of the curb and rolling the wheel 2.3.

This also applies to the rising portions of stairs.

Then, when the walkway ends and there is a vertical rise due to the curb, the tree branch wheels 2.3 immediately lower.

At this time, if you move the tip of the tree branch further downward, the wheel 2
, 3 come into contact with the base surface of the curb and the size of the step can be determined.

Note that this also works in the same way at the falling part of the stairs, and the boundary between the station platform and the track can be accurately grasped.

Furthermore, in cases such as the edge of the platform, there is a possibility that due to the blind person's carelessness, the wheels 2 and 3 of the tree branches may come off the edge and at the same time several branches may deviate and fall onto the tracks.

However, as shown in FIG. 1, the runaway prevention member 6 is disposed immediately behind the wheels 2 and 3 in the main body 1 of the present invention, so that the member 6 is placed on the platform at the same time as the wheels 2 and 3 fall. It catches on the edge and prevents the cane from running away.

Although the tip of the member 6 is located slightly above the wheels 2.3, if the main body 1 is laid too horizontally, the member 6 will come into contact with the ground.

Therefore, the school body 1 is necessarily corrected to a fixed posture, and the school body 1 always maintains a constant posture.

Therefore, the distance between the wheels 2, 3 and the blind person can be kept constant, and the position of the obstacle can be immediately perceived.

Next, if there is a relatively small unevenness on a part of the walking surface, one of the wheels 2 and 3 will move up and down.
This is perceived through the handle of the cane.

Further, when a convex portion exists between the side wheels 2 and 3, the convex portion comes into contact with the convex surface detection rod 4 which also serves as an axle, and the presence of the convex portion can be sensed.

Further, the second embodiment shown in FIG. 3 allows the user to walk while holding the main body 1 on the dominant arm side in a natural posture, thereby reducing fatigue of the dominant arm.

Furthermore, since this embodiment has a coiled portion 11 between the wheels 2, 3 and the main body 1, when the wheels 2, 3 collide with other passersby or luggage, the wheels are elastically deformed.

Therefore, there is no risk of harm to other people or cargo in the event of a collision.

In addition, in the present invention, each wheel of each of the above embodiments may be made removable or foldable.

Furthermore, the bifurcated support member 7 is attached to the tip of the main body 1 via a spring (not shown).

This is to prevent the cane from escaping if a blind person trips over a stone or other object.

That is, in the above case, the blind person's weight is applied to the cane, which causes the support member 7 to rotate or contract upward, and the escape prevention member 6 to come into contact with the ground.

Therefore, the cane can be stopped and erected to support the blind person.

The cane of the present invention has the above-mentioned configuration, and the escape prevention member 6 is formed behind the wheels 2.3 and protrudes downward at the tip of the main body. Even if the cane suddenly falls from the platform, the escape prevention member 6 will catch on the edge of the platform, preventing the cane from escaping and protecting the blind person.
