CONSTITUTION:A light emitting diode 15 is energized by a battery 6 through a switch 11, and a buzzer 14 is connected in parallel with the light emitting diode 15 through a liquid switch 12. When a push button 11B is pressed, the switch 11 is turned on, power is supplied from a battery 6 to the light emitting diode 15, and the light is emitted outside a stick 1 through a transparent part 2. To check whether or nor the light emitting diode 15 is turned on, the stick 1 is tilted so that the lower tip is raised up to a position on the level with a grip or higher, so that a liquid 13 electrically connects switch contacts 12-1 and the switch is turned on. At this time, when the light emitting element is turned on, the buzzer 14 sounds as it is also energized, and if it is not energized, the buzzer does not sound.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a cane whose middle part can emit light.

[Conventional technology]

In order to prevent being hit by bicycles or cars while walking at night, some canes have a part in the middle that lights up when operated by the person holding the cane. FIG. 3 shows an overall view of such a conventional cane, and FIG. 4 shows the block structure of its main parts. In these figures, 1 is a cane, 2 is a transparent part, 3 is a slide switch, 4 is a metal pipe, 5 is a cap, 6 is a battery, 7 is a flashing circuit,
8 is wiring, and 9 is a lamp. Move the slide switch 3 provided on the grip of the cane L by arrow B.
When sliding in the direction, power is supplied from the battery 6 to the blinking circuit 7. The blinking circuit 7 intermittently energizes the lamp 9 to cause it to blink. The light from the lamp 9 passes through the transparent part 2 in the middle of the cane l and goes out to the outside of the cane l.

[Problem N that the invention attempts to solve]

The conventional walking sticks described above have the following problems. The first problem is that it is easy for a person with normal eyes to confirm that the lamp 9 is lit, but a person with poor eyesight, such as a blind person, should carefully touch the position of the slide switch 3. The problem is that you have no choice but to do it and it is a hassle. The second problem is that if the slide switch 3 is malfunctioning or the battery 6 is exhausted, the slide switch 3
Although the lamp 9 does not light up even if it slides to the on position, it is no longer possible to confirm that the lamp is lit in that case. The present invention aims to solve these problems.

[Means to solve the problem]

In order to solve the above problems, the following measures were taken in the cane of the present invention so that even people with impaired eyesight can easily confirm that the cane is lit. That is, the present invention provides a cane that includes a battery, a manual switch section, a light emitting body that is turned on by being energized by the battery by the manual switch, and a transparent section that allows light from the light emitting body to pass through to the outside. A series circuit consisting of a buzzer and a fluid sui-nochi, which turns on when the cane is tilted and its lower tip is approximately parallel to or higher than the hand grip, is connected in parallel to the light emitting body.

[For production]

When the manual switch is turned on, the light emitter lights up. At this time, when the cane is raised above the horizontal level, electric ground → manual switch →
Power is applied from the fluid switch to the buzzer, and the buzzer sounds. Therefore, even a blind person can confirm that the luminous body is lit by simply holding the cane horizontally. Furthermore, even if the cane is dropped on the ground, the cane becomes horizontal and the buzzer sounds, making it possible to easily find the cane by relying on the sound.

【Example】

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows an overall view of the cane of the present invention, and FIG. 2 shows a block layout of the main parts thereof. The symbols correspond to those in FIGS. 3 and 4. And l1 is a switch part, II
B is a push button, 12 is a fluid switch, 12-1 is a switch contact, 13 is a fluid, 14 is a buzzer, and 15 is a light emitting diode body. In this example, a light emitting diode body is used as the light emitter, and a push button type switch is used as the manual switch. The light emitting diode body 15 has a switch section 11 from the battery 6.
The wiring is such that the i-electric power is connected via the Further, the buzzer 14 is connected in parallel to the light emitting diode body 15 via the fluid switch 12. As the fluid switch 12, for example, mercury suinochi is used. In that case, fluid 13 is mercury. When the cane 1 is held vertically as in use, the fluid 13 moves to the bottom of the fluid switch 12 and breaks the electrical connection between the swing contacts 12-1 provided at the top. This turns the switch OFF. When the cane 1 is tilted so that its lower tip is approximately parallel to or higher than the hand grip, as shown in FIG.
The fluid 13 electrically connects the switch contacts 12-1;
The switch is turned on. Although the switch portion l1 is grooved in FIG. 2 as a push button 2, it may be any other type of manual switch. Next, the operation will be explained. When the push button IIB is pressed, the switch portion 1l is turned ON, and the light emitting diode body 15 is energized from the battery 6. The light from the light emitting diode body 15 passes through the transparent part 2 and exits to the outside of the cane 1. If the light-emitting diode body 15 is one in which a blinking circuit is integrated, the light emitted from the transparent portion 2 can be blinked. A flashing circuit that is integrated with the light emitting diode body 15 has fewer failures than a flashing circuit that is provided independently. Since the cane 1 is in a vertical position during normal use, the fluid switch 12 never turns on. Therefore,
Buzzer 14 does not sound. If you want to check whether the light-emitting diode body 15 is energized, in other words, whether the light-emitting diode body 15 is lit, tilt the cane 1 so that its lower tip is approximately parallel to or more than the hand grip. Make it the same height. Then, the fluid switch 12 is turned on. At this time, if the light emitting diode l5 is energized, the buzzer l4 will also be energized, so the buzzer will sound. If the light emitting diode body l5 is not energized, there will be no sound. As a result, even a blind person can confirm that the light emitting diode body 15 is lit by simply holding the cane 1 approximately horizontally. There are also cases where the cane 1 is accidentally dropped on the ground, but it is difficult for a blind person to find it. However, since the cane of the present invention makes a buzzer sound when it is placed horizontally, it is easy to find the cane by relying on the buzzer sound. FIG. 5 shows the specific structure of the cane of the present invention. The symbols correspond to those in FIG. And 16, 17

It is pulled out to the outside through a through hole l7l made in the wall of 7. Then, due to the force between the insulating cylinder 17 and the metal pipe 4, it is brought into electrical contact with the metal pipe 4. The light emitting diode body 15 is housed in a green cylinder body 18. The wiring connected to the negative electrode of the light emitting diode body l5 is connected to a terminal 23 provided outside the insulating cylinder body, and
is brought into contact with the terminal 22. FIG. 7 is an explanatory diagram of the positive electrode wiring of the light emitting diode body. Wiring 8- connected to the positive electrode of the light emitting diode body l5
With the end of 3 exposed outside the insulating cylinder 18, attach the base 1
5-1 is fitted in the direction of arrow A. Since this is housed inside the metal pipe 4, the end of the distribution fI8-3 is sandwiched between the insulating cylinder 18 and the metal pipe 4, and comes into electrical contact with the metal pipe 4. A transparent body 24 is arranged in front of the light emitting diode body l5. Both ends of the transparent body 24 are firmly connected to the metal vibrator 4 that holds the main body of the cane 1 by a screw mechanism or the like. The part of the transparent body 24 that is not covered with the metal pipe 4 forms the transparent part 2. As the material of the light-transmitting body 24, for example, light-transmitting plastic or the like can be used. Inside the transparent body 24,
In order to maximize the intensity of light exiting to the outside, holes 25 are provided as necessary. In the example shown in FIG. 5, the metal pipe 4 also serves as the positive electrode wire that is to be wired from the battery 6 through the switch section 11.

【Effect of the invention】

As described above, the cane of the present invention provides the following effects. ■ Even a blind person can confirm that the light emitter is lit simply by holding the cane approximately horizontally. ■Also, if you accidentally drop your cane on the ground while using the light emitter, a buzzer will sound, so you can rely on the buzzer sound to find it, making it easier to find it. ■ If the buzzer does not sound even when the cane is placed almost horizontally, the likely cause is that the battery is exhausted.
You can check whether or not the battery needs to be replaced.
