Description

The present invention relates to a stick.

Among the accidents encountered by people who need a stick while walking, the number of falls and fall accidents caused by overlooking obstacles and steps at the feet in the dark is increasing, and the darkness that may lead to a particularly big accident, There is a need for a stick that helps prevent accidents on steps, down stairs and downhills.
Therefore, a headlight is provided at the front end of the handle, a shaft portion below the shaft is illuminated, and a lantern type illuminator is provided at the tip portion below the shaft. Patent Document 2 or a clip type attached to the shaft. Lighting equipment etc. are made.

For many of the above-mentioned stick lighting, it is necessary to select whether to illuminate a wide area with an appropriate brightness or to use a focused and bright spot lighting, but at the same time, it is necessary to consider the relationship with the power supply. That is, it is necessary to choose whether to take the brightness of high illuminance even if the battery life is shortened or to extend the battery life even if the illuminance is sacrificed.
In addition, spot illumination that irradiates bright spot light in the vertical direction from a high position away from the ground surface such as the end of the handle toward the illumination spot required for walking causes a large difference in illuminance inside and outside the spot, and the following The destination of one step (hereinafter referred to as the destination) tends to be dark. Furthermore, the above-mentioned spot light moves up, down, left and right with the movement of the stick, but since this movement looks like the light dances (hereinafter referred to as "light dance"), the nervous stick user dislikes it because his eyes get tired. ing.

On the other hand, there are lantern-type illuminators installed at the tip of the stick that illuminate 360 degrees around the shaft, and those that illuminate 360 degrees by converting the lower part of the stick into a luminous body using transparent acrylic. It is said that it is insufficient as the most needed front lighting to illuminate.
In addition, it is necessary to reduce the size and weight of the battery in order to attach it to the stick, and if a small battery is used to obtain high illuminance, the frequency of battery replacement will increase due to the large consumption of the battery. The question of whether to take or take battery life reignites.

Also, in terms of use, probably because there are many elderly people who say that it is troublesome to replace small batteries such as button batteries and AAA batteries, if the batteries attached at the time of purchase run out, leave them as they are and use ordinary lighting without using special lighting. I heard that there are many examples of using it as a battery.
Furthermore, I have never seen crutches used by injured or handicapped people regardless of age, even though they are often required to take action at night.
According to the above, the wand user can use it with peace of mind, and it has a bright headlight that makes it easy to see the road surface condition, a tail light with high visibility, and an auxiliary light according to the application. There was a need for a wand that would ease the anxiety of users and their families and enable them to go out in the dark.

Japanese Unexamined Patent Publication No. 2010-03868 JP-A-2002-262913

An object of the present invention is the development of a headlight having a bright headlight function, a taillight, and an auxiliary light depending on the application, which requires less time and effort for battery replacement.

In order to solve the above problems, the present invention has, for example, the eyes of an old walker in order to make the lighting suitable for the characteristics of walking for the elderly, such as the legs not rising and the stride being narrow (hereinafter referred to as the old walk). After setting it to 06 to 1M, which is a little closer to the general public, the walking distance is 0.2 to 2 meters long and 0.7 to 1.5 meters wide due to the vertically spreading light centered on the 80 cm point in front of the pedestrian. As the illumination area required for the above (hereinafter referred to as the illumination area), the illumination area is illuminated with an easy-to-see brightness.

Therefore, the light source irradiates light in the oblique lateral direction with an irradiation angle of 35 to 55 degrees toward the illumination area from a light source fixed at a low position within 15 to 55 cm below the stick.
The light in the diagonally lateral direction increases in brightness as it approaches the light source from the center (C) of the illumination area, while it becomes darker as it moves forward from the center, and the difference in illuminance inside and outside the illumination area decreases, so-called forward blur. It becomes a state and this has the effect of reducing the light dance.

When the spot in the vertical direction is transparent from the high position, the user habitually focuses on the spot, so that the light source provided at the low position (Fig. The light in the oblique lateral direction of -2) includes a blur and spreads, and the irradiation light of the LED that controls the irradiation angle through the lens produces whisker-like light (Fig. 2H) in front of the outside of the irradiation angle. As a result, this can be used as an aid to step-by-step lighting.
Further, the pedestrian looks ahead from the vicinity of the center of the illumination area, that is, the line of sight of the pedestrian using the cane follows the traveling direction of the light from a little before the center of the illumination area (FIG. 8C) to the blurred region. Since the person looks ahead, the influence on the visibility of the front part having a difference in brightness, which is a factor of the light dance, is small, and the influence of the light dance is reduced by the tip blur effect, and the tiredness of the eyes is alleviated.
In the present invention, a headlight using an LED light source, a voltage-current stabilizing circuit (hereinafter, this is referred to as a stabilizing circuit), a switch, the secondary battery, and an over-discharged overcharge protection circuit (hereinafter, this is referred to as a protection circuit). In addition to those having a charging mechanism, a taillight that can be seen from at least 5 meters behind and an auxiliary light as needed will be provided to improve the safety of walking.
As a result, the user can walk while checking the safety of the road surface centering on the lighting area so that the driver of the car drives while checking the front with the headlight, and further, the presence of the pedestrian is detected by the taillight. By explicitly preventing collision accidents or by providing auxiliary lights according to the purpose, it is possible to obtain a stick that helps protect pedestrians.

The present invention does not specify the shape of the stick. That is, it includes various types of sticks such as sticks for the elderly, mountain climbing, trekking sticks, and pine needle sticks.
The headlight and other parts used are preferably waterproof, but may be simple waterproof or non-waterproof.
In the present invention, an auxiliary light can be appropriately provided as needed, and a switch for the auxiliary light may be provided separately.
In addition, it does not specify the switch method, shape, or mounting position.
The present invention does not specify a storage location for the secondary battery, and therefore may be provided at any location such as in the handle or in the stick shaft.
It is preferable to use a protection circuit for the secondary battery, but it does not specify the installation method or location of the protection circuit.
In order to prevent fluctuations in illuminance due to battery consumption, it is preferable to stabilize the illuminance by using a stabilization circuit.
The secondary battery is preferably charged by a non-contact type, but may be a contact type or a plug or jack type.
The power receiving terminal for charging the secondary battery may be provided at any place on the stick.
The pine needles may be provided in any shape and in any place.

The present invention has the effect of reducing the walking safety of the user and the frequency of battery replacement.
