JP2024014643A - Cane with LED light that switches between strong lighting, weak lighting, flashing, and SOS Morse code flashing - Google Patents

Abstract

[Problem] This invention poses a safety problem when a person who requires a cane is difficult to recognize by a car driver if the cane falls over at night, especially during rainy weather. Additionally, if a person is lost in the mountains, the lights attached to the eastern side of the mountain will run out of battery within a few hours, making it difficult to find the person from outside. We tried to eliminate these two dangers. This relates to a cane with an LED light that can switch between four patterns. [Solution] This cane is equipped with an LED light on the outside of the main shaft at the bottom of the cane handle, which has strong lighting, weak lighting, blinking, and SOS Morse code blinking.

Description

This invention poses a safety problem for those who require a cane, as it is difficult for car drivers to recognize the person who uses the cane at night, particularly during rainy weather, if the cane is only lit.
Furthermore, if a person is lost in the mountains, the battery will run out after a few hours if the headlight is attached to the person's head, making it difficult to find the person from the outside.
We tried to eliminate these two dangers. This relates to a cane with an LED light that can switch between four patterns.

Canes are used to support the elderly and people with physical disabilities and to assist them in walking. Pedestrians' feet are unstable at night, especially when it rains. Furthermore, when walking on roads with few streets, it is difficult for car drivers to recognize them, which is even more problematic than for able-bodied people.

Until now, a cane has a light that is driven by an internal power source in the main shaft near the handle of the cane. (Patent Document 1)
A cane (Patent Document 2) has been proposed in which an LED lighting device is built into the vicinity of the lower part of the cane to illuminate the front.

Jito No. 3206545 JP2019-037718

Overview of the invention

Problems that the invention seeks to solve

This had the following drawbacks.

The one described in Patent Document 1 is illuminated by an internal power source in the main shaft of the cane, but there is no flashing, only lighting, and unlike able-bodied people, disabled people walk at a slower speed, which could be dangerous. Unable to act quickly. To the driver of the vehicle at night, simply turning on the lights gives the impression that the vehicle is stationary. What's more, safety is even more problematic when it rains at night.

The one described in Patent Document 2 is a cane that has an LED lighting device built into the main shaft of the cane near the bottom of the cane to illuminate the front. This also only lights up, and the lighting time is extremely short compared to flashing.

Both of the above two points are great, but the problem is that there is no flashing and only lighting, and when using LED lighting, the lighting time is extremely short compared to flashing, and those who frequently use the cane at night may need to use the battery inside. must be replaced many times.

There are no canes used in the mountains that have lighting or flashing equipment.
The present invention has been made to eliminate the above-mentioned drawbacks.

Means to solve problems

This cane is equipped with an LED light on the outside of the main shaft at the bottom of the cane's handle that has strong lighting, weak lighting, flashing, and SOS Morse code flashing.

Effect of the invention

The present invention is an LED light wand having the above configuration.
According to the present invention, the LED light body is integrated with the main shaft of the cane, so you can safely walk with the cane at night, and the LED light can be turned on and off in dangerous areas where there are many cars. This allows car drivers to see more flashing lights than lights, so they can clearly see people walking and can detect danger. Therefore, no matter how bright the light is, if you look at the light from a car, the blinking light is much more obvious and is less likely to lead to an accident. At night or when it rains, it's hard to compare the fact that a flashing light makes it easier for motorists to see that someone is there than a light on.

In addition to canes used by the elderly and people with disabilities, there are also canes for mountain climbing.This cane has an LED light attached to the outside of the bottom of the handle, similar to the one above, and can be turned on with a strong light, a weak light, or a normal flash. One type is blinking, and the other type is blinking with SOS Morse code function.
The cane used for mountain climbing can be illuminated at night with a headlight, but if you are lost in the mountains, the battery of the headlight will run out in a few hours and there is nothing you can do about it. , This LED light has four switching patterns, and in particular, the SOS Morse code blinks for nearly 20 hours with one AAA battery and one 1.5V battery inside the LED light itself. By flashing the SOS light, searchers can clearly see the SOS light from both the sky and the ground, regardless of whether the missing person is in the mountains or near a river. A climbing cane is most effective if it is not used primarily for lighting, but rather as a cane to protect your life in case of an emergency, or as a cane for SOS Morse code.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

What is shown in FIGS. 1, 2, and 3 is an embodiment of the cane with an LED light that can switch between strong lighting, weak lighting, blinking, and SOS Morse code blinking according to the present invention.

Figure 1 shows how to attach two holes (10) at the bottom of the handle of a cane (2) and attach a small LED light body that can be switched between strong lighting, weak lighting, blinking, and SOS Morse code blinking. It is a diagram of a state in which it is attached to the hole (5) with a screw and a butterfly nut.

FIG. 2 is an exploded view of the LED light.

FIG. 3 is a circuit diagram of the LED light. The LED light circuit boosts the voltage with YN6033 of U1, and switches its output using 28196 of U2 to perform blinking of KED and dimming by PWM.

It is a figure which attaches the LED light main body of this invention to a cane. It is an exploded view of the LED light main body. It is a wiring circuit diagram of an LED light.
