Abstract
A walking cane for the blind or the aged which emits warning flashes of light is disclosed. The cane is shaped to have a tubular shaft and a handle having an angled section extending laterally from one end of the shaft to be grasped by the hand of an user. Provided on the cane are two spaced apart light sources, one positioned at intermediate portion of the length of the shaft and the other positioned at such portion behind the user's hand as to be exposed backwardly of the person holding the cane. The former light source is utilized to give a warning by being flashed on and off to the others moving forward upon or passing across the person holding the cane, while the latter to give the same to the others approaching behind that person. Accordingly, these two longitudinally spaced light sources are cooperative to arouse all other persons in the vicinity to take notice of the person holding the cane and therefore to enhance the security of the person holding the cane.
Description
- This invention is directed to a walking cane, more particularly to an electrically illuminated walking cane for the blind or the aged.
- Conventional canes of that kind have been basically white finished for being readily seen by others in the vicinity. However, it is only effective in daytime and may be inconspicuous or invisible at night to threaten the security of a blind and an aged person in walking. To this end, there have been provided illuminated canes such as disclosed in U.S. Pat. No. 4,236,544, incorporating a single light source which is controlled to flash on and off when the ambient illumination or light level decreases below a predetermined level for calling the attention of other passengers and drivers on motor vehicles to a passing person holding that cane. In the cane of this type, only one light source is disposed at such middle portion of the length as to be positioned in front of the user when it is in use, so that it can give the warning to the other persons passing transversely of or moving forward upon the person holding the cane but it substantially fails to give the warning to the persons, particularly the drivers on motor vehicles approaching behind the user since the light is concealed by the user oneself from those other persons. Accordingly, the above prior cane is found to be practically ineffective to the other persons behind the user, thus is not safe enough to protect the blind person holding the cane in the ever-worsening traffic scene. Further, the blind person using this prior cane is unable to determine whether the light is turned on or off and therefore cannot be aware whether he is walking in a dark place or not, such dark condition lowering the visibility of the other persons in the vicinity and making it difficult to ascertain the blind person. Thus, the blind person finds no way to protect oneself against the other persons whose visibility is lowered at such a dark condition and is liable to be exposed to danger which would be avoided if the blind person be aware that he is walking in a dark place which requires more attention to his walking behavior. Still with this arrangement of not being capable of alarming the user whether the cane is lighted or not, it is possible to waste an incorporated battery when the user, after its use, leaves the cane unswitched in such a dark place as to automatically actuate the cane to continue the flashes of light.
- The above disadvantages or drawbacks has been eliminated by the present invention which includes a cane shaft, an angled handle extending laterally from one end of the cane shaft, and spaced light sources being operated simultaneously to emit flashes of light. In general, the cane of the type having an angled handle at its one end is normally utilized by a blind or aged person grasping the handle at a location approaching the cane shaft to be inclined forwardly such that the user can easily feel the way with that cane. Accordingly, the outer portion of the angled handle will be left to expose in the backward direction of the person holding the cane, while the cane shaft is positioned in front of that person. The present invention is devised, in view of this manner in which a blind or aged person holds the cane with the angled handle, to provide first and second light sources in spaced relation longitudinally along the cane, one disposed at the intermediate portion of the length of the cane shaft for emitting the warning flashes of light to the other persons passing across or approaching forward upon the person holding the cane and the other at such portion of the handle to be exposed backwardly of that person for emitting the warning flashes of light to the other persons approaching behind that person.
- Accordingly, it is a primary object of the present invention to provide a walking cane for the blind or aged capable of giving the warning not only to the oncoming persons but also to the other persons behind that person holding the cane to enhance the security of the user and protect against the collision by the other persons or the motor vehicles.
- In the preferred embodiment of the present invention, both first and second light sources are controlled in response to the ambient illumination level to issue an intermittent flashes of light when the level decreases below a predetermined value, and a warning buzzer is included for alarming the user when the light of sources are operative to flash on and off, so that a sightless user can pay more attention to his walking behavior in a dark place to protect himself against the others lowering their visibility in such dark condition, ensuring the security of the blind walking in a dark place. Also with this feature that the blind person can determine by the audible signal whether the cane is used in a dark place or not, the cane can be prevented from being left unswitched in a dark place when out of use.
- It is therefore another object of the present invention to provide a walking cane capable of assuring the security of the blind walking in a dark place as well as preventing an incorporated battery from being wasted when out of use.
- In accordance with the one embodiment of the present invention, the buzzer is connected in series with the light sources so that the user can be immediately informed of any defection of the light sources by the resulting interruption of the audible signal from the buzzer when the cane is used in a dark circumstance, so that he can replace rapidly and safely the defective light sources.

- Referring now to the drawings and particularly to Figs. 1 and 8, there is illustrated one preferred embodiment of a walking cane for the blind or the aged comprising a
tublar cane shaft 3 having at the middle of the length thereof afirst light source 1 and a generally J-shaped handle 4 having at its ridge portion or radially outer edge portion asecond light source 2, saidhandle 4 having an integral stem which is connected to the upper end of thecane shaft 3 by means of askirt 5 and asleeve 6. The first andsecond light sources cane shaft 3 is a transparent hollow cylinderical member of a substantially uniform diameter made of synthetic resins such as fiber reinforced polyester or fiber reinforced vinyl chloride. The outer surface of thecane shaft 3 is dyed with a white translucent and fluorescent material which is capable of transmitting light except theportion 8 adjacent tofirst light source 1,such portion 8 being defined between a pair of annular bands 9 secured in spaced relation longitudinally on the middle portion of the length of thecane shaft 3 and being dyed with red translucent material capable of transmitting red light. Attached to the lower end of thecane shaft 3 is atip member 10 made of durable synthetic resin such as vinyl chloride. Thehandle 4 made of acrylic resin or the like stuff material has the integral stem which is force fitted into one end of theskirt 5 made of opaque ABS resin so as to join thehandle 4 to theskirt 5. Theskirt 5 has at the other end aportion 11 internally threaded for threadably mating with the external thread at one end of saidsleeve 6 made of the same opaque material. The upper end of thecane shaft 3 is force fitted within the other end opening of thesleeve 6 and bonded by an adhesive, so that thehandle 4 can be removed from thecane shaft 3 by loosening theskirt 5 with respect to thesleeve 6 for replacing abattery 12. Thebattery 12 comprises a pair of dry cells which are connected in series to provide a power source for first andsecond light sources warning buzzer 14 such as a piezoelectric buzzer or a electromagnetic buzzer disposed within saidskirt 5 to issue an intermittent sound in synchronism with saidlight sources battery case 13 for receiving the dry cells is fixedly inserted in the upper portion of thecane shaft 3 with its open end located within saidsleeve 6 through which the cells will be accepted and removed. Saidbuzzer 14 is secured within theskirt 5 at the portion behind said internally threadedportion 11 so that the intermittent beep from thebuzzer 14 pass through perforations in the surrounding wall of theskirt 5. Inserted in an electric circuit including thebattery 12, thebuzzer 14, first andsecond light sources manual switch 16 which is mounted and partly within thesleeve 6 and which is connected in series with said light responsive switch means 7. Themanual switch 16 has aleg 17 which extends through the wall of thesleeve 6 such that theswitch 16 rotates about theleg 17 between two operating positions, i.e., on-position and off-position, theswitch 16 being manipulated by aknob 18 projecting on the outer surface of thesleeve 6. Electrical arrangement of theswitch 14 will be described in the later paragraph. - Referring now to Figs. 4 through 6, said light responsive switch means 7 comprises a
photosensor 20 which is a cadmium sulfide (CdS) cell to detect outdoor illumination, a Schmitt trigger 21, anastable multivibrator 22, aswitching transistor 23, and aresistor 24 coupled in series with thecell 20 to determine an illumination level below which the Schmitt trigger 21 responds to the resulting raised input voltage to activate themultivibrator 22 which in turn provides a repetitive low frequency output of about one Hertz so as to cause theswitching transistor 23 to conduct the on/off operation, whereby the first andsecond light sources buzzer 14 produces the intermittent beep. These elements are packaged, as shown in Fig. 3, on a printedcircuit board 25 mounted on aholder 26 extending integrally from saidbattery case 13 so that thephotosensor 20 will receive the light through the translucent wall of thecane shaft 3. In this embodiment, the above illumination level is set to be 50 lux as measured at dusk so that the flashes of light and the intermittent beep will begin to issue at such dark outdoor illumination level. Other photosensors such as phototransistor or photodiode may be utilized in replace for the above photoconductive cadmium sulfide cell. Axially extended from saidholder 26 is aninner tube 27 of transparent material which is coaxially received within thecane shaft 3. Theinner tube 27 has therein the LED offirst light source 1 at the location corresponding to saidportion 8 dyed with the red translucent material and has its free open end closed by areflective plate 28 which reflects the light from theLED 1 to brighten the wholeinner tube 27 particularly the portion near the LED l, so that sufficient amount of light from theLED 1 will pass through thered portion 8 of thecane shaft 3 and is vividly viewed as red light by the other person in front of a person holding the cane. - The LED of
second light source 2, on the other hand, is the one emitting red light and is molded in thehandle 4 with its luminescent top being projected thereon at the ridge portion or radially outer portion, suchportion including LED 2 being located practically behind the hand of the person grasping thehandle 4 when he walks with the assistance of the cane so thatLED 2 is exposed backwardly of the person holding the cane, warning the other persons behind that person by the flashes of red light. - Included within said
skirt 5 is aconcentric terminal block 30, as shown in Figs. 4, 7 and 8. Thisterminal block 30 has on its side wall three axially spacedconductive rings conductive boss 34 which is electrically connected to theadjacent ring 31 and is brought into the abutting contact with the plus terminal of thebattery 12 when theskirt 5 is screwed onto thesleeve 6. These three spaced rings, i.e.,first ring 31,second ring 32, andthird ring 33 are arranged so that when theskirt 5 is engaged with thesleeve 6 they are brought into electrical connection respectively withfirst contact member 41,second contact member 42, andthird contact member 43 all being located on the inner surface of thesleeve 6 in angularly spaced relationship with each other. These spacedrings terminal block 30 so as to be kept in contact with thecorresponding contact members skirt 5 and thesleeve 6 so long as theskirt 5 is sufficiently screwed on thesleeve 6 to attain the abutting relationship between theboss 34 with the plus terminal of thebattery 12. Saidterminal block 30 is in the form of hollow cylinder with saidboss 34 on its end base and has therein twoterminals buzzer 14 and second light sources (LED) 2 both disposed on the side of thehandle 4, theseterminals third rings buzzer 14 is connected in series with first and second light sources (LED) 1 and 2 as shown in Figs. 4 through 6, thebuzzer 14 andsecond LED 2 are connected in series between the second andthird rings terminal block 30 as best shown in Fig. 4, and first light source (LED) 1 is connected through said printedcircuit board 25 between first andthird contact members transistor 23 on the printedcircuit board 25 is connected tosecond contact member 42 and the emitter of the same is connected to the minus terminal of thebattery 12. As shown in Figs. 4, 7 and 8, saidfirst contact member 41 is attached to the lower end of theleg 17 of saidmanual switch 16 so as to be rotated therewith for connecting and disconnecting first contactingmember 41 with thering 31 or the plus terminal of thebattery 12, that is, themanual switch 16 is set to on-position when thecontact member 41 is turned to abut against thering 31 and is set to off-position when it is removed from thering 31. Accordingly, the electric circuit including themanual switch 16, the light sensitive switch means 7, thebuzzer 14, first and second light sources (LED) 1 and 2 is completed when theskirt 5 is engaged with thesleeve 6 to bring all therings corresponding contact members - The cane constructed as above can be utilized by a blind person who fumbles the
manual switch 16 on or an aged person. As shown in Fig. 2, it is the practice that the person holding that cane to feel the way therewith will incline the cane forwardly grasping he handle 4 at the portion near the upper end of thecane shaft 3, so that second light source (LED) 2 is to be positioned behind the hand of the person to be exposed backwardly of that person and first light source (LED) 1 is in front of that person. When evening came, for instance, to decrease the outdoor illumination level below a predetermined level or 50 lux for the present embodiment, thephotosensor 20 will detect such decrease in the outdoor illumination level to activate the on/off operation of the switchingtransistor 23, whereby first and secondlight sources buzzer 14 will issue an intermittent beep. At this time, firstlight source 1 blinking in front of the person holding the cane will be recognized by the other oncoming persons and the drivers on vehicles, precisely by the persons approaching forward upon or passing across the person walking with the cane, while at the same time secondlight source 2 blinking behind the person will be recognized by the other persons or the drivers approaching behind that person, so that the other persons approaching the person holding the cane from all directions can take notice of that person, promoting the safe walking of the blind or aged person holding the cane. Thebuzzer 14 issuing an intermittent beep in synchronism with first and secondlight sources buzzer 14 being connected in serial with first and secondlight sources light sources buzzer 14. - Another embodiment of the present invention will be described with reference to Figs. 9 through 11 in which the same reference numerals as used in the preceding figures are used to indicated like parts to avoid the necessity for repeating the relevant discussion. This embodiment adopts, in contrast to the above embodiment, the parallel combination of the
buzzer 14, first and secondlight sources terminal block 30 somewhat differs from that of the foregoing embodiment, the difference will be easily understood in Fig. 9 when compared with Fig. 4, the former of which is for the present invention and shows that thebuzzer 14 is connected between the first andsecond rings third rings terminal block 30. The other features of the present invention is the same as the foregoing embodiment with the exception that a current-limitingresistor 45 and azener diode 46 are introduced in the circuit, as shown in Figs. 9 and 10, the current-limitingresistor 45 acting to protect first and second light sources (LED) 1 and 2. Thezener diode 46 is connected between the collector of the switchingtransistor 23 and thesecond contact member 42 to be serially connected to thebuzzer 14 in order that the buzzer will cease to operate before the first and secondlight sources battery 12 drops. Accordingly, the user can easily acknowledge the exhaustion of the battery so as to replace the battery with a new one before it fails to operate first and secondlight sources - Referring to Figs. 12 and 13, there is shown a further embodiment of the present invention wherein a
handle 50 of T-shaped configuration is provided at the upper end of thecane shaft 53 of the same construction as above. The present embodiment has the same functional arrangement as the foregoing embodiments with the exception of the buzzer which is eliminated from the present invention. Thehandle 50 is shaped to have a downwardly extendingstem 54 the lower end of which joins thecane shaft 53 and a laterally extendinggrip 55 of hollow member in which abattery 56 and theholder 57 thereof are received. Theholder 57 is provided at its one end with acap 58 screwed onto the open end of theholder 57. Thecap 58 being exposed at one end ofgrip 55 has on its outer surface aslot 59 for receiving a coin for easy operation of replacing thebattery 56. Located at the opposite end of thegrip 55 is amanual switch 60 which is a slide switch connected in series with the light responsive switch means packaged on the printedcircuit board 61 inserted in thecane shaft 53, the light responsive switch means including the photosensor has the same construction as the foregoing embodiments. Light emitting diodes (LED) are likewise employed as first and secondlight sources cane shaft 53 at the intermediate portion along the length thereof to be adjacent to the redtinted portion 62 through the entire wall of which the light from theLED 51 will pass to warn the oncoming persons by red flashes of light. Second light source (LED) 52 is disposed at the end of thegrip 55 in juxtaposition with saidbattery cap 58, such end of thegrip 55 is defined as being far from thestem 54 in such a way that the user will grip thehandle 50 at the location approaching the opposite end of thegrip 55. Thus, secondlight source 52 is to be positioned behind the hand of the user so as to be exposed backwardly of the user, warning the other person behind that user. - The above embodiments and particularly the drawings are set forth for purposes of illustration only. It will be understood that many variations and modifications of the embodiment herein described will be obvious to those skilled in the art, and may be carried out without departing from the spirit and scope of the invention.
