Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a walking stick mainly used by blind people.

[Conventional technology]

Conventionally, blind people have walked with curbs on curbs along the road, windbreaks, etc. Therefore, for example, as described in Japanese Utility Model Application Laid-Open No. 59-44434, an obstacle sensor or the like is provided on the shaft portion of the cane, and an alarm device such as a vibrator is provided on the gripping portion of the cane to prevent an obstacle to a user. A blind cane was proposed to inform people.

[Problems to be solved by the invention]

However, the blind cane according to the conventional example or the cane according to another conventional example includes batteries inside, and even if rechargeable batteries can be used for these batteries, the battery is There is a problem that it is extremely troublesome to take out only the battery, charge it with an appropriate charger, and store the charged battery again in the cane.

When a dry battery or the like is used as the battery, there is an inconvenience that it needs to be always replaced.

Furthermore, a system for searching the position of a blind person, an elderly person, etc. using a cane has not been disclosed at all in the past, and therefore,
It was extremely difficult to confirm the location.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a cane that is easy to handle, can detect at least an object in front, and does not need to remove an internal battery or the like that is consumed by use. The purpose of.

A second object of the present invention is to provide a cane that can inform the position of a person who uses the cane to the outside.

[Means for solving problems]

The cane according to claim 1, which meets the first object, is provided in an intermediate portion of a lower side of a shaft having a grip portion at an upper portion thereof, and an objective sensor for detecting an object on the front side of a wearer, and the objective. A wand having a built-in alarm device that is connected to a detection sensor and issues an alarm when the object detection sensor detects the object, and at least a rechargeable battery that serves as a power source for the wand. The charging receiving terminal for supplying electricity is exposed so that it can be connected to the charging feeding terminal provided at a specific place.

The cane according to claim 2 which meets the first and second objects is the cane according to claim 1, further comprising a transmitter and an antenna for transmitting a radio wave for notifying the position of the cane inside the shaft. It is provided.

[Action]

The cane according to claim 1 or 2, wherein an object detection sensor provided in the lower middle part of the shaft for detecting an object on the front side of the wearer, and an alarm when the object detection sensor detects the object. Since the alarm device is provided, if an obstacle or the like is present on the front surface of the cane, this is detected and an alarm is issued from the alarm device.

Although the battery is consumed by use, the battery is made of a rechargeable battery and the charging receiving terminal is exposed to the outside, so the user was placed at a specific position after using the cane. Charging of the battery is started by placing the cane with the power receiving terminal in contact with the power receiving terminal.

Further, in the cane according to claim 2, since the transmitter for transmitting the radio wave and the antenna are arranged inside the shaft, the position of the cane can be detected by receiving the radio wave. By this, the position of the person who uses the cane can be specified. In particular, since the cane is rod-shaped, even a relatively long antenna can be housed so that it cannot be seen from the outside.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention.

FIG. 1 is a perspective view of a cane according to an embodiment of the present invention.
2 and 3 are side views showing the usage of the cane.

As shown in FIG. 1, a cane 10 according to an embodiment of the present invention is
A shaft 12 provided with a bent grip portion 11 on the upper part, an object detection sensor 13, a height detection sensor 14, a transmitter 15, an antenna 16, and a battery 17 provided on the shaft 12, and an upper part of the shaft 12. It is configured to have an exposed power receiving terminal 18 for charging, an alarm device 19 provided on the grip portion 11, and another alarm device 20. These will be described in detail below.

The objective detection sensor 13 is an optical sensor that detects reflected light of a light beam that is emitted forward in a direction perpendicular to the longitudinal direction of the shaft 12. In addition, the high and low sensor 14
Is also composed of an optical sensor for detecting a change in reflected light of a light beam emitted downward in the longitudinal direction of the shaft 12.

The grip 11 includes a vibration generator that constitutes an alarm device 19,
A vibrator piece connected to the vibration generator is provided, and when an obstacle is detected in front by the object detection sensor 13, the vibrator piece vibrates to give an alarm signal to the hand.

Further, the grip portion 11 is provided with a synthetic sound generator which is another alarm device 20, and is adapted to notify the signal from the height sensor 14 by voice.

Inside the shaft 12, a transmitter that constantly emits weak radio waves
An antenna 16 for transmitting radio waves from the transmitter 15 and the transmitter 15 is provided, and the weak radio waves are received by receiving antennas provided at a plurality of points in the area, and the staff 10 at the monitoring center.
The position of can be recognized.

The battery 17 that supplies power to the battery is a rechargeable battery, and by connecting a pair of +/- power receiving terminals 18 to a corresponding power supplying terminal 21 arranged at a specific position,
Charging of 17 is started.

In FIG. 1, 22 is an automatic lighting lamp at night, 23 is a length adjusting shaft, and 24 is a switch.

Therefore, when the cane 10 is used, as shown in FIG. 2, for example, when there is a step or an object 25 in front, it is detected by the object detection sensor 13 and the alarm device 19 is activated. Then, as shown in FIG. 3, when there is a down stage 26 in the front, it is detected by the height sensor 14 and another alarm device 20 is activated to notify.

By the above operation, the front stage, the object 25, and the down stage 26 can be detected separately by the alarm devices 19 and 20. In addition,
In FIGS. 2 and 3, 27 indicates a walking surface.

[Effect of device]

As can be seen from the above description, when the blind person holds the cane and carries it, if there is an object in front of the cane, the cane according to the first and second embodiments activates the alarm device. Therefore, the safety of walking by the blind can be secured.

Then, the charging power receiving terminal for supplying electricity to the battery is exposed on the side surface of the shaft and can be connected to the charging power feeding terminal provided at a specific place. By disposing the cane, the battery can be automatically charged without disassembling the shaft and removing the battery inside. Therefore, the cane is extremely useful and easy for the blind to handle.

Particularly, in the cane according to the second aspect, since the transmitter and the antenna for transmitting the radio wave are provided inside the shaft, the position of the cane can be searched from the outside, and thus the cane is held. The whereabouts of blind people can be confirmed.
