BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to a lighting and alerting device for a walking stick, and more particularly, to a lighting and alerting device for a walking stick which comprises lighting, flashing and sound alerting functions to provides added value for the walking stick

2. Description of the Prior Art

Accordingly, walking sticks are usually used to support disabled patients or seniors when they're walking. However, as a walking aid for disabled patient or senior, walking stick is made of wood or metal with no added functions, therefore it is disadvantageous in:

1. When a senior or disabled patient walks in the dark, he/she has to carry extra lighting equipment with him/her, in this case, it is not convenient for him/her when walking;

2. Should the senior or disabled patient accidentally fall, he/she is not able to immediately call for help since the walking stick doesn't have an alerting function.

Therefore, the above-mentioned traditional walking sticks present several shortcomings to be overcome.

In view of the above-described deficiencies of traditional walking sticks, after years of constant effort in research, the inventor of this invention has consequently developed and proposed a lighting and alerting device for a walking stick in the present invention.

These features and advantages of the present invention will be fully understood and appreciated from the following detailed description of the accompanying Drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer to FIG. 1 to FIG. 3 for the lighting and alerting device for a walking stick, which mainly comprises:

• • a walking stick body 1, the cross-sectional shape of the walking stick body 1 is slightly T-shaped, a battery container 11 is disposed at one side of the walking stick body 1, while a power socket 12 is disposed on the walking stick body 1 to couple with the battery container 11 to charge the battery inside the battery container 11, and a sound bore 13 is disposed at one side of the walking stick body 1;

a control device 2 comprising:

a manual power generating unit 21, the manual power generating unit 21 comprises a handle 211, a power generating device 212 and a power storing device 213, the handle 211 is placed outside a lateral side of the walking stick body 1 and is integrated with the walking stick body 1 when not in use, while the power generating device 212 and the power storing device 213 are disposed inside the walking stick body 1; electric power generated by winding the handle 211 to drive the power generating device 212 is transmitted to the power storing device 213 for storage, so as to let electric power be transmitted to a lighting unit 24, a light alerting unit 25 or a sound alerting unit 26 through a multistage control switch 22;

a power supply unit 23, the power supply unit 23 can be a dry battery or a rechargeable battery, the power supply unit 23 is disposed in the battery container 11 at one side of the walking stick body 1, wherein the power supply unit 23 can also supply power to the lighting unit 24, the light alerting unit 25 or the sound alerting unit 26 through the multistage control switch 22;

the lighting unit 24, the lighting unit 24 comprises at least a luminous body 241, the luminous body 241 can be a high brightness LED protruding out of a front side surface of the walking stick body 1 and electrically connecting the lighting unit 24 to the power storing unit 213 or the power supply unit 23 through the multistage control switch 22;
