Abstract

The present invention relates to a light emitting cane used for climbing mountains or walking and, more specifically, a self-generating electricity light emitting cane, which supplies electric power to a light source in a self-generating electricity manner using piezoelectric elements and accordingly improves safety and convenience of users as well as visibility, comprising a grip; a supporting frame connected to the lower part of the grip; a tap installed on the lower end of the supporting frame; and a light emitting tool wherein the light emitting tool comprises a first electricity generating part which is installed in the tap and generates electricity from pressurized load via the supporting frame; a battery charging electricity generated from the first electricity generating part; a light source which receives electric power from the battery; and a switch which assigns and blocks the electric power from the battery to the light source.

Description

A cane with a piezoelectric element

[0001] The present invention relates to a light emitting stick that can be used for walking or climbing, and more particularly, to a light emitting stick that can be used for walking or climbing, Self-powered luminous cane.

Generally, a cane is used mainly for the elderly, the person with a physical disability, walking in the dark at night, walking on a long road, early mountain climbing, long-distance hiking for a long time, It is a kind of walking aids.

Conventionally, many kinds of canes have been commercialized. However, most of the above-mentioned canes are simple structures in which a length-adjustable stick is attached to the lower part of the handle, or a multi-purpose cane with various functions is sometimes proposed. However, When a person with a disability uses a cane, visibility around the area (such as a car or a motorcycle) can not be obtained at night, resulting in frequent accidents.

Also, in the case of night walking, it was difficult to identify the obstacle ahead (pit, protruding jaw, etc.), which also caused a safety accident.

In addition, many hikers use canes for safe walking, safety accidents are also a problem at dawn or at night when the roads are uneven and the roads are always dangerous.

If you use a walking stick with one hand and use a light when walking, pedestrians will be disturbed on the road, losing the balance of the body, and the weight of the light bulb is burdensome for the elderly.

For this purpose, Korean Utility Model Registration No. 0413605, published in the Republic of Korea, discloses a handle structure for a cane having a lighting function.

However, since the above-described handle for a cane uses a battery as a power source, it is frequently required to replace a battery, and environmental pollution occurs due to a waste battery.

An object of the present invention is to provide a light emitting stick capable of self-power generation by supplying electricity to a light source using a piezoelectric element.

According to an aspect of the present invention, there is provided a self-powered luminous wand comprising: a handle; A support coupled to a lower portion of the handle; A tab installed at the lower end of the support; A first power generating unit installed inside the tab and generating electricity by a load applied through the support, a battery for charging electricity generated from the first power generating unit, a light source for receiving power from the battery, And light emitting means including a switch for applying and cutting off power from the battery to the light source.

As described above, according to the present invention, it is possible to provide a light emitting stick capable of supplying power to a light source by self-power generation because self-power generation is possible when walking using a piezoelectric element.

Such luminous sticks not only enhance visibility at night, but also can enhance safety and user convenience.

1 is a perspective view showing an embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a self-powered luminous staff of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the light emitting stick of the present invention includes a handle 10, a support 20, a tab 30, and light emitting means.

The handle 10 has a structure in which a frame made of a skeleton is covered with a soft rubber. Preferably, a plurality of acupressure protrusions for promoting blood circulation may be formed on the handle 10. Needless to say, the handle 10 can be changed into various shapes and structures depending on the use of the staff.

The support (20) is formed at the bottom of the handle (10). The support 20 can be adjusted to an appropriate length depending on the user's body. The support base 20 may be formed of various materials such as resin, metal, and wood. As an example, a lightweight aluminum alloy material may be used with a certain strength.

The support base 20 has an empty pipe structure inside. The support 20 may have a variable length structure as shown in FIG.

A tab 30 is provided at the lower end of the support 20. The tab 30 may be formed of a hard rubber material capable of being elastically deformed. The tab 30 is a portion in contact with the ground during walking, and mitigates an impact applied to the support 20.

The light emitting means includes a first power generation unit 40 for generating electricity, a battery (not shown) for charging electricity generated from the first power generation unit 40, a light source 60, and a switch 65 for applying and cutting off power from the battery to the light source 60.
