JP2001353194A - Cane for blind with alarm - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve the problems that it is difficult to recognize a blind at night and it causes traffic accidents or the like because only white canes are on the market although recently blind people often go out at night. SOLUTION: For this cane for the blind, the function of sensing the impact of hitting a ground surface, emitting light and notifying people around is provided in a conventional cane for the blind.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind wand with a light for notifying surrounding people when walking at night.

[0002]

2. Description of the Related Art In recent years, going out of the blind at night has been increasing. Nevertheless, as shown in FIG. 6, a blind stick with a red mark applied to a white stick is only commercially available.

[0003]

However, with the above-mentioned conventional blind stick, it is difficult to recognize the blind stick at night, which causes a traffic accident or the like.

Accordingly, an object of the present invention is to provide a blind wand with a warning function, which has a function of detecting the impact of hitting the tip of the blind cane with the ground and notifying surrounding people with light. Is what you do.

[0005]

Means for Solving the Problems The first invention (claim 1)
The conventional blind stick has a small battery, a light emitting diode and a switch function to detect the impact, and the switch is turned on by the impact of hitting the ground, and the light emitting diode is turned on instantly. It is a blind stick with warning.

A second invention (corresponding to claim 2) is a first invention.
A warning wand with a warning, characterized in that the wand with a small battery, a light emitting diode and a switch function for sensing an impact are integrated into a removable structure.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a conceptual diagram showing a blind cane with a warning according to an embodiment of the present invention at the time of actual use. FIG. 2 is a sectional view showing a blind stick with a warning according to the embodiment of the present invention. FIG. 3 is a sectional view showing a switch for sensing an impact when the ground is hit according to the embodiment of the present invention. FIG. 4 is a cross-sectional view illustrating the warning unit when the warning unit according to the embodiment of the present invention is integrated and made detachable. FIG.
1 is a perspective view showing a commercially available blind stick. The details will be described below.

FIG. 1 shows a conceptual diagram of actual use of a blind stick with a light warning according to the present invention. Hold one end of white stick 1
A red mark 3 is provided on the other end, and a light warning unit 4 is attached to one end of the red mark. People who use the blind cane recognize the obstacle by tapping lightly on the ground with the tip of the cane. For this reason, the impact of hitting the ground is transmitted to the warning portion of the present invention, and it is possible to warn surrounding people by light.

FIG. 2 is a cross-sectional view of the warning unit 4 using light, in which a light emitting diode 5, a switch 7 for detecting an impact, and a small battery 8 are housed in a translucent resin case 8, and a bottom cover is provided. 9 and is fixed to the tip of the white bar 1.

FIG. 3 is a sectional view of the switch 7 for sensing an impact. A cylindrical conductive cylinder 10 and a switch piece fixed conductive rod 12 are fixed to a fixed insulating plate 11. A switch piece 13 that senses an external impact is fixed to the switch piece fixed conductive rod 12 and is also electrically connected. Since the cylindrical conductive cylinder 10 is a cylinder, it can sense a shock in two directions.

FIG. 4 is a sectional view when the warning unit is made detachable. A light-emitting diode 5, a switch 7, and a small battery 8 are incorporated in a translucent resin case 6. Further, three or more compression springs 14 for fixing the white bar 1 are mounted on the translucent resin case 6, and a conical surface 6 a for fixing to the center portion is provided regardless of the external dimensions of the white bar 1. .
14a shows the state of the compression spring 14 when the white bar 1 is inserted.

FIG. 5 shows a conventional stick for a blind person, comprising a white stick 1, a handle 2, a red mark 3, a fall prevention band 18 and a tip portion 19.

[0014]

According to the present invention, a blind person can recognize a blind stick from a distance by using the blind stick of the present invention so that the light flashes due to the impact of hitting the ground during walking at night. Thus, a blind stick with a warning that can prevent a traffic accident or the like can be provided.
