Walking Stick Having Generating and Illuminating Functions

A walking stick includes a stick body, a circuit board, a control switch, a storage battery, a generating unit, a control handle, a plurality of light emitting members, two lamp shades, a lighting unit, a buzzer, and a level detector. The light emitting members and the lighting unit can emit light beams outwardly so that the walking stick can provide a lighting function at the night or on a darker place. The control handle is pivoted relative to the stick body to drive the generating unit to generate an electric power so that the walking stick has a manually generating function without needing an external power supply. When the walking stick falls down (or the user falls down onto the ground), the buzzer is operated to emit a sound so as to provide a warning and notifying function.

Referring to the drawings and initially to FIGS. 1-3, a walking stick in accordance with the preferred embodiment of the present invention comprises a stick body 10, a circuit board 20 mounted in the stick body 10, a control switch 21 mounted on the stick body 10 and electrically connected with the circuit board 20 to control operation of the circuit board 20, a storage battery 26 mounted in the stick body 10 and electrically connected with the circuit board 20 to supply an electric power to the circuit board 20, a generating unit 29 mounted in the stick body 10, a control handle 15 pivotally mounted on the stick body 10 and connected with the generating unit 29 to drive the generating unit 29 to generate the electric power which is stored by the storage battery 26, a plurality of light emitting members 27 and 16 mounted on the stick body 10 and each electrically connected with the circuit board 20 to emit light beams outwardly from the stick body 10, two lamp shades 13 and 14 mounted on the stick body 10 to receive and cover the light emitting members 27 and 16 respectively, a lighting unit 24 mounted on the stick body 10 and electrically connected with the circuit board 20 to emit light beams outwardly from the stick body 10, a buzzer 25 mounted in the stick body 10 and electrically connected with the circuit board 20 to emit sound signals outwardly from the stick body 10, a level detector 28 mounted in the stick body 10 and electrically connected with the circuit board 20 to detect a level of the stick body 10, a USB (universal serial bus) socket 23 mounted on the stick body 10 and electrically connected with the circuit board 20, and a transformer socket 22 mounted on the stick body 10 and electrically connected with the circuit board 20.

The control switch 21 and the transformer socket 22 are mounted on the circuit board 20. The transformer socket 22 is electrically connected with an electric transformer (not shown). The generating unit 29 is electrically connected with the circuit board 20 and the storage battery 26 and is provided with a rotatable driven portion 290. The storage battery 26 is located above the generating unit 29. The control handle 15 has a first end provided with a drive portion 150 pivotally mounted on the stick body 10 and combined with the driven portion 290 of the generating unit 29 to drive and rotate the driven portion 290 of the generating unit 29 to generate the electric power and a second end provided with a holding portion 151. The drive portion 150 of the control handle 15 is provided with a fixing hole 152 secured on the driven portion 290 of the generating unit 29.

The stick body 10 consists of two casings 113 and 114 which are combined together. Each of the two casings 113 and 114 of the stick body 10 has a periphery provided with a protruding fixing portion 107 to combine the two casings 113 and 114 of the stick body 10 together. The stick body 10 has a substantially T-shaped profile.

The stick body 10 has an upper portion provided with a receiving recess 109 to receive the buzzer 25, two receiving chambers 100 and 101 to receive the two lamp shades 13 and 14 respectively, and an elongate receiving slot 111 to receive the level detector 28. The lamp shade 13 has a side provided with a plurality of receiving holes 130 to receive the light emitting members 27 respectively. The two receiving chambers 100 and 101 of the stick body 10 are located opposite to each other and are directed toward two opposite directions. Each of the two receiving chambers 100 and 101 of the stick body 10 protrudes outwardly from the upper portion of the stick body 10. The receiving slot 111 of the stick body 10 is perpendicular to a longitudinal direction of the stick body 10. The receiving recess 109 of the stick body 10 has an outer side provided with a plurality of apertures 110 that are arranged to form a circular shape.

The stick body 10 has an inner portion provided with an elongate receiving space 103 to receive the generating unit 29 and the storage battery 26. The receiving space 103 of the stick body 10 has a peripheral wall provided with a locking groove 102 to fix the circuit board 20.

The stick body 10 has a periphery provided with a mounting hole 104 connected to the receiving space 103 of the stick body 10 for mounting the USB socket 23, a mounting bore 105 connected to the receiving space 103 of the stick body 10 for mounting the control switch 21, a mounting aperture 106 connected to the receiving space 103 of the stick body 10 for mounting the transformer socket 22 and a mounting groove 108 connected to the receiving space 103 of the stick body 10 for mounting the lighting unit 24. The USB socket 23 protrudes outwardly from the mounting hole 104 of the stick body 10, the control switch 21 protrudes outwardly from the mounting bore 105 of the stick body 10, the transformer socket 22 protrudes outwardly from the mounting aperture 106 of the stick body 10, and the lighting unit 24 protrudes outwardly from the mounting groove 108 of the stick body 10. The USB socket 23, the control switch 21 and the transformer socket 22 are in line with each other and are located opposite to the lighting unit 24.

The stick body 10 has a side provided with a receiving channel 17 to receive the control handle 15. The receiving channel 17 of the stick body 10 has a wall provided with a passage 112 connected to the receiving space 103 of the stick body 10 to allow passage of the drive portion 150 of the control handle 15.

In operation, referring to FIGS. 4-6 with reference to FIGS. 1-3, after the control handle 15 is pulled outwardly from the receiving channel 17 of the stick body 10 as shown in FIG. 4, the control handle 15 is pivoted relative to the stick body 10 as shown in FIG. 5 to drive the generating unit 29 to generate the electric power which is stored by the storage battery 26. Alternatively, the USB socket 23 is electrically connected with an external power supply, such as a charging unit (not shown) to supply the electric power to the storage battery 26. Then, the control switch 21 is pressed to operate the circuit board 20 which turns on the light emitting members 27 and 16 and the lighting unit 24, so that the light emitting members 27 and 16 and the lighting unit 24 can emit light beams outwardly from the stick body 10 as shown in FIG. 6 to provide a lighting and illuminating function.

On the other hand, referring to FIG. 7 with reference to FIGS. 1-3, when the walking stick falls down (or the user falls down onto the ground), the level detector 28 is operated to send a signal to the circuit board 20 which operates the buzzer 25 to emit a warning sound as shown in FIG. 7 so as to provide a warning and notifying function.

Accordingly, the light emitting members 27 and 16 and the lighting unit 24 can emit light beams outwardly so that the walking stick can provide a lighting and illuminating function at the night or on a darker place. In addition, the control handle 15 is pivoted relative to the stick body 10 to drive the generating unit 29 to generate an electric power so that the walking stick has a manually generating function without needing an external power supply. Further, the USB socket 23 is electrically connected with a charging unit to supply the electric power to the storage battery 26 so that the walking stick can also be electrically connected with an external power supply to enhance the versatility of the walking stick. Further, when the walking stick falls down (or the user falls down onto the ground), the buzzer 25 is operated to emit a sound so as to provide a warning and notifying function.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
