  • The cane is an important tool for people who has trouble in walking or for climbers, and it is also a tool for walkers in rural and country areas. Generally, safety is considered when the cane is selected to be used. Usually, for example, the user can swing the cane to expel dangerous animals or even persons who attack the user.
  • However, the conventional cane is designed to have basic functions only, without considering the safety requirements effectively. At least based upon the above point, the present invention provides the design of a multi-functional cane. Several embodiments are given below to illustrate the present invention. However, the present invention is not limited to the embodiments given below.
  • FIG. 1 is a schematic side view of a multi-functional cane according to an embodiment of the present invention. Referring to FIG. 1, the multi-functional cane 100 of this embodiment includes a handle member 102, a rod member 104, and a multi-functional circuit system. The multi-functional circuit system includes a plurality of devices with different functions that are distributed in the rod member 104 and the handle member 102, and the rod member 104 is coupled with the handle member 102 to form a mechanical structure of the cane 100.
  • The multi-functional circuit system includes, for example, an alarm device 108, an illumination device 112, an expel device 106, a power unit 110, and a control unit 102 a. The power unit 110 provides a driving power required by the devices. As shown in the figure, the control unit 102 a includes a control terminal part disposed on the handle member 102, so as to operate the plurality of devices of the multi-functional circuit system.
  • The control unit 102 a includes inner circuits (not shown in FIG. 1), and the control terminal part is disposed, for example, on the handle member 102, and includes, for example, a display element 102 b to display operation states of corresponding devices. The actual circuit of the control unit 102 a is shown in the block diagram of FIG. 7. However, the circuit design of FIG. 7 is not the only choice, which can be modified depending upon actual requirements. The above devices with various functions are disposed, for example, within a plurality of inner spaces in the integrated structure formed by the rod member 104 and the handle member 102, and they are distributed properly.
  • For example, the illumination device 112 is designed to be close to the ground when it is used to illuminate the roads. The illumination device 112 is, for example, an LED light source. Moreover, for example, the alarm device 108 or the expel device 106 is suitable for sending alarms or expelling dangerous animals respectively, so that the two devices are designed to be disposed at the upper end of the rod member 104. The expel device 106 is, for example, an ultrasonic expel device used to expel animals such as wild dogs.

To facilitate controlling the devices, the control terminal of the control unit 102 a is disposed on the handle member 102. In other words, various functional devices may be properly disposed on any appropriate position of the cane 100. The expel device 106 is, for example, used to expel any dangerous animal. As the acoustic frequency of animals is different from that of human beings, the generated ultrasonic waves can expel, for example, dogs, or even snakes or bees, etc. Moreover, for example, the main function of the alarm device 108 is to send out sounds, for example, an alarm sound for help, or further send out an alarm sound to expel hostile people. In other words, the alarm device 108 is used to provide alarm signals of sounds.
  • In addition, for example, when the user is lost in countryside or in a mountain, and needs to seek for external help, the conventional cane cannot provide the function of contacting the exterior. However, the multi-functional circuit system of the cane of the present invention further includes a wireless device 102 c, which is, for example, a wireless communication device. The user of the cane can contact the exterior at any time via the wireless communication device 102 c. No matter the user himself/herself or people, things, or objects around the user need help, the multi-functional cane can be used to contact the exterior.
  • Moreover, the multi-functional circuit system of the cane further includes a positioning device 118 used to obtain a local position information. The positioning device 118 is, for example, a receiver of Global Positioning System (GPS), so as to obtain the local position information that can be sent out via the wireless communication device 102 c when necessary. Moreover, the multi-functional circuit system of the cane further includes a Mayday device 120, for example, to send out a Mayday signal via the wireless communication device 102 c. In particular, when the user of the cane is injured, and cannot communicate with the exterior by voice, the Mayday device 120 can send out a Mayday signal, and the positioning device 118 can inform the exterior about the user's local position.
  • The wireless communication device 102 c includes, for example, a voice device that forms an integrated structure with the handle member 102. The voice device includes, for example, a microphone and a speaker, etc., so as to communicate with the exterior via voice. If the user is still able to speak, the user can also seek for external help by voice.
  • Moreover, any one or both of the handle member 102 and the rod member 104 of the cane 100 have a storage space 114 for storing an article. The storage space 114 is, for example, used for storing the object 116 taken along by the user, for example, first aid medicine.
  • The alarm device 108 of the cane 100 includes, for example, a sound alarm device and/or a light alarm device, which is not only simply used for expelling dangerous animals, but also used for sending local Mayday signals and so on.
  • The control terminal part of the control unit 102 a of the cane 100 includes a plurality of control keys disposed on the handle member 102 to facilitate controlling operations. The control keys also can be designed as a single selecting control key to save space. For such a selecting control key, for example, the device to be controlled is selected by rotating or pressing the key, and the start, stop, or other operations are achieved by pressing the key.
