BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an improvement on walking stick structure, more particularly one, which has illuminating, charging, and alerting functions, and can send out sound so as to repel mosquito.

2. Brief Description of the Prior Art

People are paying more attention to recreational activities with demanding better quality life. Arrangement of holiday activities has become an important issue. Hiking and mountaineering are among the recreational activities. Walking sticks can help reduce the burden on the users in hiking and mountaineering. If a person uses a walking stick properly, he/she will save strength and reduce the burden on the legs, and avoid tripping in walking uphill.

A conventional walking stick includes a handle, and a supporting rod joined to a bottom of the handle, and except for helping the user to walk, it has no other functions to help the user avoid various dangerous situations that might come up in hiking and mountaineering.

SUMMARY OF THE INVENTION

It is a main object of the invention to provide a walking stick that can serve other purposes besides helping the user to walk. The walking stick of the present invention includes a supporting rod, a handle having two shell parts coupled together, a circuit board, an alert lamp, a buzzer, an illuminating lamp, and a generator. The circuit board is positioned in the handle, and has a flash alert circuit, a buzzing sound circuit, an illumination circuit, and a charging circuit; a charging socket is connected to the charging circuit; a battery set is connected to the circuit board in the handle; the alert lamp is fitted on the handle and connected to the flash alert circuit while the buzzer is connected to the buzzing sound circuit; the illuminating lamp is connected to the illumination circuit; a switch element is used to turn on/off the above electrical and electronic units. A cranking bar is connected to the generator for making the generator. The battery set is connected to the generator for storing electricity generated by the generator. Therefore, the walking stick has illuminating, charging, and alerting functions, and can send out sound so as to repel mosquito.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 to 4, a preferred embodiment of a walking stick in the present invention includes:

a handle 1; the handle 1 includes two shell parts 11 coupled together, and has a holding room 111 inside; a first one of the shell parts 11 has a through hole 112;

a supporting rod 2 joined to a lower side of the handle 1; the supporting rod 2 can be a straight rod 21 (FIG. 1) with a suitable length or a telescopic rod 22 (FIG. 2);

a generator 12 positioned in the holding room 111 of the handle 1; the generator 12 has a gear set 121, and a generating motor 122 therein; the gear set 121 includes a first gear 1211, and a last gear 1212; the generating motor 122 is connected to the last gear 1212 of the gear set 121;

a circuit board 13 positioned in the holding room 111 of the handle 1; the generating motor 122 is connected to the circuit board 13; the circuit board 13 has a flash alert circuit, a buzzing sound circuit, an illumination circuit, and a charging circuit thereon;

a charging socket 10 connected to the charging circuit on the circuit board 13 and passed through the through hole 112 of the first shell part 11 of the handle 1 for connection with an external electrical/electronic appliance, e.g. a mobile phone, and a laptop computer;

a cranking bar 14 fitted on an outer side of one of the shell parts 11 of the handle 1; the cranking bar 14 is connected to the first gear 1211 of the gear set 121;

a battery set 15 connected to the circuit board 13 and the generator 12; the battery set 15 are nickel hydrogen storage batteries for storing the electricity generated by the generating motor 122;

an alert lamp 16 fitted on rear ends of the shell parts 11 of the handle 1 and connected to the flash alert circuit; the alert lamp 16 has an alert lamp cover 161;

a buzzer 17 fitted to the rear ends of the shell parts 11 of the handle 1 under the alert lamp 16 and connected to the buzzing sound circuit on the circuit board 13;

an illuminating lamp 18 fitted on a front end of the handle 1 and connected to the illumination circuit on the circuit board 13; the illuminating lamp 18 has a light-gathering cover 181, and a lamp cover 182 positioned next to an outer side of the light-gathering cover 181; and

a switch element 19 fitted on the front ends of the shell parts 11 of the handle 1 right above the illuminating lamp 18; the switch element 19 is connected to the circuit board 13 at one end, and has a pressing part 191 at the other end.

Referring to FIGS. 3 to 9, when the user turns the cranking bar 14, the first and the last gears 1211 and 1212 of the gear set 121 will turn, and in turn the generating motor 122 will generate electricity, which will be stored in the battery set 15, and supplied to the various electric/electronic devices. The user is allowed to press the pressing part 191 of the switch element 19 so as to activate the alert lamp 16 for the alert lamp 16 to flash to make other persons to notice the user. The user is also allowed to press the pressing part 191 of the switch element 19 so as to activate the buzzer 17 for the buzzer 17 to send out mosquito repelling sound, dog repelling sound or supra music. The user is also allowed to press the pressing part 191 of the switch element 19 so as to make the illumination lamp 18 produce light, which will pass through the light-gathering cover 181, and reach a farther position with increased brightness; thus, the user can see more clearly in the dark.

From the above description, it can be easily seen that the walking stick structure of the present invention has the following advantages:

1. The user of the walking stick can see clearly in the dark to avoid danger with the help of the light emitted from the illumination lamp, which will reach a farther position with increased brightness because of the light-gathering cover.

2. The flash lamp of the walking stick will help the user noticed by other persons. Therefore, other persons can see the user clearly, avoiding the risk of the user getting lost in an open country or mountain.

3. With the buzzer and the buzzing sound circuit on the circuit board, the walking stick can send out mosquito/dog repelling sound to protect the user in bush walking, mountaineering, and hiking in an open country. And, the walking stick can send out supra music to make the user feel clam when he/she is walking in an open country.

4. The walking stick has the charging socket, which allows other electrical/electronic appliances such as laptop computers and mobile phones to be connected thereto and charged.

5. Because of the cranking bar and the generator, electricity can be generated, and supplied to the various electric/electronic elements of the walking stick in an open country or mountain if the walking stick runs out of electricity.
