Description

Cane and vibration dynamo device

The present invention relates to a cane, and more particularly to a cane having a light source.

A cane equipped with a light source is known in order to recognize the user of the cane in the surroundings. Examples of such canes include Japanese Patent Application Laid-Open No. 2011-10997 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2016-30112 (Patent Document 2). As power generation means of a light source, Patent Document 1 discloses the use of a piezoelectric element, and Patent Document 2 discloses the use of a magnetostrictive element.

JP 2011-10997 A JP 2016-30112 A

However, the inventor paid attention to the problem that the canes disclosed in Patent Documents 1 and 2 have difficulty in light emission, and made this a problem.

That is, an object of the present invention is to provide a cane that can easily emit light.

The present inventor has paid attention to the fact that when the cane is used, the main body constituting the cane moves in the vertical direction, and has considered using this movement of the main body for power generation of the light source. The present invention has been completed by conceiving that an electromagnetic induction method is used as a means for generating electric power using the motion of the main body.

That is, the cane of the present invention includes a main body, a vibration dynamo device housed in the main body, and a light source that emits light from the vibration dynamo device. The vibration dynamo device includes a cylindrical member housed inside the main body in a state in which the reciprocating motion can be performed in the vertical direction, an outer periphery of the cylindrical member, a coil disposed inside the main body, and the cylindrical member And a vibrating member that includes a magnet (magnet) and is housed inside the cylindrical member in a state that allows reciprocating motion along the extending direction.

According to the cane of the present invention, the cylindrical member is accommodated in the main body part that moves in the vertical direction when the cane is used, and is movable in the vertical direction, and the vibration member is accommodated in the cylindrical member. A coil is disposed outside the cylindrical member. For this reason, in this invention, the vibration member of an electromagnetic induction type vibration dynamo device can be efficiently moved up and down by utilizing the vertical movement of the main body when using the cane. Therefore, since the power generation efficiency of the vibration dynamo device provided in the cane can be improved, the cane of the present invention can easily emit light.

In the cane of the present invention, the portion of the vibrating member that contacts the cylindrical member is preferably a sphere.

When the vibrating member reciprocates, the portion of the vibrating member that contacts the cylindrical member is a sphere, so the sliding portion between the vibrating member and the cylindrical member is in point contact. For this reason, since the sliding area of a vibration member and a cylindrical member can be reduced, the resistance at the time of a vibration member vibrating can be reduced. For this reason, since the efficiency which converts vibration (kinetic) energy into an electrical energy can be improved, since power generation efficiency can be improved more, it can be made to light-emit more easily.

In the cane of the present invention, preferably, the vibration member includes three or more elements, and the elements positioned at both ends are spheres.

When the oscillating member reciprocates, the contact area can be reduced when the sphere constituting the oscillating member contacts the cylindrical member. For this reason, since the power generation efficiency of a vibration dynamo device can be improved more, the cane which makes it light-emit more easily is realizable.

Preferably, in the cane of the present invention, the remaining part of the three or more elements is a sphere and / or a column, and the outer diameter of the sphere located at both ends is larger than the outer diameter of the remaining sphere and / or the column. .

This makes it possible to reduce the contact area between the vibrating member and the cylindrical member when the vibrating member reciprocates because the spheres located at both ends of the elements constituting the vibrating member are in contact with the cylindrical member. For this reason, since the power generation efficiency of a vibration dynamo device can be improved more, it can be made to light-emit more easily.

Preferably, the cane of the present invention further includes a pair of magnets that are magnetically repelled from each other and disposed at each of a lower end portion of the tubular member and a portion of the main body portion that faces the lower end portion of the tubular member.

Thus, when the vibration member moves to the lower end portion of the cylindrical member by the vertical movement of the main body, the vibration member can be easily moved upward by the repulsive force of the pair of magnets. For this reason, since the power generation efficiency of a vibration dynamo device can be improved more, it can be made to light-emit more easily.

In the cane of the present invention, the light source is attached to the tubular member, the tubular member is located at the lower end of the cane, and the main body located at the lower end of the cane is translucent.

This makes it possible to realize a cane in which a light source that can easily emit light is arranged at the lower end.

The stick of the present invention may further include a handle disposed at the upper end of the main body, and the light source may be disposed near the handle.

This makes it possible to realize a cane arranged in the vicinity of the handle whose upper end is a light source that can easily emit light.

The cane of the present invention may further include a solar panel arranged in the vicinity of the handle.

By using a configuration that can be charged by a solar panel, the light source can emit light more reliably.

As described above, according to the cane of the present invention, light can be easily emitted.

(Embodiment 1)
A walking stick according to an embodiment of the present invention will be described. As shown in FIG. 1, a cane 1 according to Embodiment 1 of the present invention includes a main body 2, a handle 3 provided at the upper end of the main body 2, and an elastic provided at the lower end of the main body 2. And a buffer body 4.

The main body 2 is a shaft extending in the vertical direction, and has a cylindrical shape. The main body 2 may be in the form of a hollow bar having at least a part inside, and a part thereof may be solid. A hollow portion of the main body 2 accommodates a cylindrical member 11, a coil 12, and a vibration member 20 of a vibration dynamo device 10 to be described later. In the main body 2, the portion in which the vibration member 20 is accommodated is formed of a nonmagnetic material. The non-magnetic material is a substance that is not a ferromagnetic material, and includes a paramagnetic material, a diamagnetic material, and an antiferromagnetic material, such as a metal such as aluminum and a synthetic resin such as plastic.

In this embodiment, since the vibration dynamo device 10 is housed in the lower end portion of the main body portion 2, at least the lower end portion is hollow and has translucency. Specifically, in the main body 2, the lower end is a cylinder formed of a resin having translucency, and the remaining part is a cylinder formed of metal, and these cylindrical members are engaged with each other. is doing. For example, polycarbonate is used as the resin. Moreover, since the main-body part 2 is a part visually recognized, the design may be given to the remainder.

It should be noted that the inner diameter (hollow diameter) of the main body portion 2 of the present embodiment is slightly larger than the case 14 described later (the case 14 having the protrusions 14a when the protrusions 14a are provided).

The handle 3 is a grip part for the user to hold the cane 1. The handle 3 is preferably hollow inside.

The elastic buffer 4 covers the lower end (tip) of the main body 2. In FIG. 2, the elastic buffer body 4 covers the lower end portion of the portion formed of the material having translucency in the main body portion 2. The elastic buffer body 4 is an elastic body such as rubber, and is, for example, a foot rubber.

As shown in FIG. 2, a vibration dynamo device 10 is accommodated in the main body 2. The vibration dynamo device 10 includes a tubular member 11, a coil 12 disposed on the outer periphery of the tubular member 11, a vibrating member 20 accommodated inside the tubular member 11, and both ends of the tubular member 11. The

repulsion members

13 a and 13 b arranged, the casing 14 surrounding the coil 12, and the rectifier circuit 15 connected to the coil 12 are included. The cylindrical member 11 of the present embodiment is located at the lower end of the cane 1.

The cylindrical member 11 is made of a nonmagnetic material, has a hollow rod shape inside, and both ends are open. The cylindrical member 11 of the present embodiment extends in the vertical direction in FIG. In addition, the outer shape and inner shape (hollow shape) of the cylindrical member 11 are not specifically limited, A circular shape, a rectangular shape, etc. are mentioned in cross-sectional view. The cylindrical member 11, the outer shape, and the inner shape of the present embodiment are cylindrical in a sectional view. In addition, the internal diameter (hollow shape diameter) of the cylindrical member 11 of this Embodiment is a little larger than the vibration member 20 mentioned later.

A coil 12 is wound around the outer periphery of the cylindrical member 11. For this reason, the cylindrical member 11 also serves as a bobbin for the coil 12. Although the coil 12 of this Embodiment is provided in a part of outer periphery of the cylindrical member 11, you may be provided in the perimeter of the cylindrical member 11, and the area | region where the outer periphery of the cylindrical member 11 isolate | separated May be provided. The coil 12 is, for example, a solenoid coil.

The vibrating member 20 is provided inside the cylindrical member 11 in a state where reciprocating motion is possible along the extending direction of the cylindrical member 11. Since the coil 12 is disposed on the outer periphery of the cylindrical member 11, the vibrating member 20 reciprocates inside the coil 12. The vibrating member 20 includes a magnet, and the coil 12 generates a voltage by the reciprocating motion of the vibrating member 20. That is, since the vibrating member 20 reciprocates along the winding axis direction of the coil 12, an alternating current is generated in the coil 12. The vibration member 20 will be described later.

Note that a magnet is a permanent magnet. The magnet is magnetized in the reciprocating direction (vertical direction). The magnetization (magnetization) method is not particularly limited. For example, there is a method in which a magnet material is fixed at the center of the air-core coil, a pulse high current is passed, and magnetization is performed in the axial direction. The material of the magnet is not particularly limited, but it is preferable to use a Nd—Fe—B sintered magnet from the viewpoint of showing a high magnetic force.

Repulsion

members

13 a and 13 b are provided at both ends of the cylindrical member 11. The

repulsion members

13 a and 13 b close the openings at both ends of the cylindrical member 11. The vibration member 20 that reciprocates is accommodated inside the cylindrical member 11 by the

repulsion members

13a and 13b.

The

repulsion members

13a and 13b include a vibrating member 20 and a magnet that repels magnetically. The

repulsion members

13 a and 13 b magnetically repel the vibration member 20 approaching the

repulsion members

13 a and 13 b toward the central portion facing the coil 12. For this reason, each of the magnets constituting the

repulsion members

13a and 13b has a polarity so as to be magnetically repelled with the vibration member 20. As will be described later, since the vibrating member 20 reciprocates in the vertical direction, the magnet strength of the repelling member 13b disposed at the lower end is greater than that of the repelling member 13a disposed at the upper end.

In addition, it may replace with the

repulsion members

13a and 13b, or may use together the member of the nonmagnetic body which obstruct | occludes the both ends of the cylindrical member 11. FIG. In the case of a non-magnetic material, it is preferably formed of an elastic material such as resin or rubber from the viewpoint of reducing damage to the vibration member 20 due to reciprocating motion.

A housing 14 is provided to accommodate the vibration member 20, the cylindrical member 11, the coil 12, and the

repulsion members

13a and 13b. The housing 14 is made of a nonmagnetic material.

The protrusion 14 a is provided on the outer peripheral surface of the housing 14. Since the protrusion 14 a is a portion that contacts the inside of the main body 2, the protrusion 14 a is formed to be in point contact with the main body 2. The protrusion 14a may be integrally formed with the cylindrical member 11 or may be formed by attaching another member. A plurality of protrusions 14 a in the present embodiment are formed along the extending direction of the cylindrical member 11.

The rectifier circuit 15 is connected to the coil 12. The rectifier circuit 15 rectifies the alternating current generated in the coil 12. The rectifier circuit 15 is, for example, a voltage doubler full wave rectifier circuit.

Further, a charging circuit (not shown) connected to the coil 12 may be provided. The charging circuit charges the direct current converted by the rectifier circuit 15. The charging circuit includes a rechargeable battery such as a NiH battery, an electric double layer capacitor, and the like. In this case, the life can be extended.

Here, the vibration member 20 will be described in detail with reference to FIGS. A portion of the vibration member 20 that contacts the cylindrical member 11 is a sphere.

As shown in FIGS. 2 to 6, the vibrating member 20 includes three or

more elements

21a, 21b, 22a, 22b, 23a, 23b, 24a, 24b, and the three or more elements are in a reciprocating direction. They are arranged in parallel along (the vertical direction in FIG. 1). Of the three or more elements, the

elements

21a, 21b, 22a, 22b located at both ends are spheres. The remaining parts of the three or more elements, that is, the

elements

23a, 23b, 24a, 24b located at other than the both ends (center part) are pillars in the structure (

elements

23a, 24a) shown in FIGS. The structure shown in FIG. 6 (

elements

23b and 24b) is a sphere. Note that the sphere and the column include those whose outer shape means a sphere and a column, and whose inside is a cavity. Further, the column includes a cylinder, a prism, a disk shape, and the like, and is a cylinder in the present embodiment.

As shown in FIGS. 2 to 6, the outer diameters of the spheres located at both ends are larger than the outer diameters of the remaining spheres and / or columns. In this case, the spheres located at both ends are portions that contact the cylindrical member 11 in the vibration member 20. In the vibration member 20, the outer diameters of the two spheres located at both ends are substantially the same. Substantially the same means that each of the two spheres at both ends contacts the cylindrical member 11 when the vibration member 20 reciprocates. The outer diameter of the sphere is a diameter. The outer diameter of the column is the diameter of the circle on the bottom surface in the case of a cylinder, and the diameter of the circumscribed circle on the bottom surface when the bottom surface of the column is an n-gon (n is an integer of 3 or more).

In the structure shown in FIGS. 4 and 6, the spheres located at both ends (

elements

21a and 22a in FIGS. 4 and 6) are yokes, and the rest of three or more elements (elements 23a, FIG. 4). 24a,

elements

23b and 24b) in FIG. 6 are magnets. In the structure shown in FIGS. 3 and 5, the elements constituting the vibration member 20 (

elements

21b, 22b, 23a, and 24a in FIG. 3, and

elements

21b, 22b, 23b, and 24b in FIG. 5) are made only of magnets. When the elements constituting the vibration member 20 are composed of magnets, or are composed of magnets and yokes, they are held by magnetic attraction, so that three or more elements of the present embodiment are These are formed only by magnets or only by magnets and yokes, and hold each other only by magnetic attraction.

Note that the yoke is soft iron that amplifies the attractive force of the magnet, as long as it contains iron, and includes soft magnetic materials. In the present embodiment, a steel ball is used as the spherical yoke.

The vibration member 20 is not particularly limited as long as the vibration member 20 is large enough to freely reciprocate inside the cylindrical member 11. However, the vibration member 20 includes the vibration member 20 and the vibration member 20 of the vibration dynamo device 10 including the vibration member 20 illustrated in FIG. 6. An example of specific dimensions is given. The inner diameter of the cylindrical member 11 is 10.5 mm, for example. The outer diameter of the spheres (

elements

21a and 22a) located at both ends of the vibration member 20 is, for example, 10.0 mm. The remaining spherical body (

elements

23b and 24b) located in the center of the vibration member 20 has an outer diameter of 9.5 mm.

The vibration member 20 shown in FIGS. 2 to 6 is an example, and is not particularly limited. For example, the vibration member 20 includes two elements, and the two elements are magnet spheres. Also good. Further, the vibration member 20 may include five or more elements.

A light source 30 emitted by the vibration dynamo device 10 is provided. The light source 30 is not particularly limited as long as it emits light when a current is applied, and a light emitting element or the like is used. Specifically, an LED, an incandescent bulb, a discharge lamp, or the like can be adopted. The light source 30 is arranged so that the emitted light is visually recognized in the surroundings.

As shown in FIG. 2, the light source 30 of the present embodiment is attached to the cylindrical member 11. Specifically, the light source 30 is attached to the upper end portion of the casing 14 in which the tubular member 11 is accommodated, and is connected to the rectifier circuit 15, so that the light source 30 is located at the lower end portion of the cane 1. Since the main body 2 located at the lower end of the cane 1 is translucent, the light source 30 is visible from the outside.

It should be noted that a switch (not shown) for switching the light source 30 on and off may be provided.

Further, a storage battery for causing the light source 30 to emit light may be provided inside the main body 2 or the handle 3.

A magnet 40 is provided at the lower end of the main body 2. The magnet 40 is disposed at a portion facing the repulsion member 13 b disposed at the lower end portion of the cylindrical member 11. The magnet 40 and the repulsion member 13b are arranged so as to repel each other. That is, the polarity of the magnet 40 is arranged so as to repel the magnet of the repulsion member 13b. For this reason, the magnet 40 and the repulsion member 13b magnetically repel the cylindrical member 11 approaching the magnet 40 upward.

A plate-like member 41 is disposed at the lower end of the main body 2 in order to make the magnet 40 face the repelling member 13b inside the main body 2. The plate-like member 41 closes the opening at the lower end of the main body 2. A magnet 40 is attached on the plate-like member 41. The plate-like member 41 is made of a magnetic material, and for example, a metal washer can be used.

Subsequently, the operation of the cane 1 according to the present embodiment will be described with reference to FIGS. The user uses the cane 1 as a walking aid by holding the handle 3 and moving the main body 2 vertically while moving the elastic cushion 4 close to or away from the ground.

As the main body 2 moves in the vertical direction, the cylindrical member 11 accommodated in the main body 2 reciprocates in the vertical direction.

The reciprocating motion of the cylindrical member 11 in the vertical direction causes the vibrating member 20 to reciprocate along the extending direction (vertical direction) of the cylindrical member 11 inside the cylindrical member 11. As a result, the vibrating member 20 reciprocates in the coil 12 disposed on the outer periphery of the cylindrical member 11, so that the magnetic flux lines generated from the magnet of the vibrating member 20 are orthogonal to the coil 12, and induction is performed at that time. An induced current is generated as an electromotive force. Since the magnet included in the vibration member 20 repeatedly enters and exits the coil 12, an alternating current is generated in the coil 12.

AC current generated in the coil 12 is transmitted to the rectifier circuit 15 via a wiring (not shown) connected to the coil 12. Full-wave rectification is performed by the rectifier circuit 15 to rectify an alternating current into a DC power supply, and is charged by the charging circuit.

When light is emitted from the light source 30 such as at night, the light source 30 is turned on. As a result, the current charged in the charging circuit is transmitted to the light source 30 to emit light. When the current charged in the charging circuit is small, a current is passed from the storage battery (not shown) to the light source 30. Thereby, when a user walks using cane 1, since a part of cane 1 can be made to emit light, the user of cane 1 can be made to recognize in the circumference.

When the light source 30 does not emit light such as during the daytime, the light source 30 is turned off. When the vibrating member 20 is reciprocated in this state, the charging circuit can be charged with the current generated in the coil 12 via the rectifier circuit 15.

In the present embodiment, when the cane 1 is used, the cylindrical member 11 and the vibration member 20 are accommodated in the body portion 2 that moves in the vertical direction so as to be movable in the vertical direction. For this reason, the vibration member 20 of the electromagnetic dynamo vibration dynamo device 10 can be moved in the vertical direction with a light load by using the vertical movement of the main body 2 when using the cane 1. That is, the movement stroke is increased by the vibration member 20 that moves in the vertical direction and the vertical movement of the cylindrical member 11 that accommodates the vibration member 20. Therefore, since the power generation efficiency of the vibration dynamo device 10 provided in the cane 1 can be improved, the light can be easily emitted even if the force applied to the cane 1 is weak.

As described above, the cane 1 according to the present embodiment can provide a safety visual effect in a dark environment such as nighttime, and thus is suitable for walking aids such as elderly people and visually impaired people, walking aids such as mountain climbing, and the like. Can be used.

Moreover, since the cane 1 of the present embodiment employs an inexpensive electromagnetic induction method as the vibration dynamo device 10, the cost can be reduced.

In the present embodiment, the portion of the vibrating member 20 that contacts the cylindrical member 11 is a sphere. Thereby, when the vibration member 20 reciprocates in the cylindrical member 11, the spheres positioned at both ends, which are elements of the vibration member 20, contact the cylindrical member 11, so that the vibration member 20 and the cylindrical member 11 are The vibrating member 20 slides in the contact state. Thereby, since the sliding area of the vibration member 20 and the cylindrical member 11 can be reduced, contact resistance (sliding resistance) becomes small. Since the vibration member 20 is easy to move, the kinetic energy (vibration energy) of the vibration member 20 due to the force applied to the vibration dynamo device 10 can be efficiently converted into electric energy by the coil 12. Therefore, since the power generation efficiency of the vibration dynamo device 10 can be improved, the light source 30 can easily emit light.

In the present embodiment, as shown in FIGS. 3 to 6, the vibration member 20 includes three or

more elements

21a, 21b, 22a, 22b, 23a, 23b, 24a, 24b, and elements 21a located at both ends. , 21b, 22a, 22b are spheres, and the remainder of the three or more elements (

elements

23a, 23b, 24a, 24b) are spheres and / or pillars, and spheres (

elements

21a, 21b, 22a) located at both ends. 22b) is preferably larger than the outer diameters of the remaining spheres (

elements

23b, 24b) and columns (

elements

23a, 24a). In addition, as shown in FIGS. 4 and 6, the spheres (

elements

21a and 22a) located at both ends are yokes, and the remaining parts of the three or more elements (

elements

23a, 23b, 24a and 24b) are magnets. More preferably. As a result, the contact resistance between the vibration member 20 and the cylindrical member 11 during the reciprocating motion of the vibration member 20 can be reduced, and the generated magnetic force can be reduced by having the yoke effect of the central magnet and the yokes located at both ends. Since it can raise, power generation efficiency can be improved more.

Further, the cane 1 of the present embodiment has a pair of

repulsion members

13a and 13b that are disposed at both ends in the extending direction of the cylindrical member 11 and include a vibrating member 20 and a magnet that repels magnetically. Therefore, when the vibration member 20 moves upward, the vibration member 20 easily moves downward due to the repulsive force with the repulsion member 13a, and when the vibration member 20 moves downward, the vibration member due to the repulsion force with the repulsion member 13b. 20 easily moves upward. For this reason, even if the force applied to the cylindrical member 11 is light, the vibration member 20 moves easily. Therefore, since the power generation efficiency of the vibration dynamo device 10 can be further improved, the light source 30 can emit light more easily.

In addition, the cane 1 of the present embodiment includes a repelling member 13b disposed at the lower end portion of the cylindrical member 11 and a magnet 40 disposed at a portion of the main body portion 2 that faces the lower end portion of the cylindrical member 11. The repulsion member 13b and the magnet 40 are magnetically repelled. When the cylindrical member 11 moves downward, the cylindrical member 11 easily moves upward due to the repulsive force between the repulsive member 13 b and the magnet 40. For this reason, since the power generation efficiency of the vibration dynamo device 10 can be further improved, the light source 30 can emit light more easily.

Further, in the present embodiment, when the cylindrical member 11 reciprocates in the vertical direction, a protrusion 14 a is provided on the outside of the housing 14 that houses the cylindrical member 11 and the coil 12, and the protrusion 14 a is formed on the main body 2. Touch. For this reason, since a contact area can be reduced compared with the case where the housing | casing 14 contacts the main-body part 2, contact resistance becomes small. Therefore, since the cylindrical member 11 can be easily reciprocated in the vertical direction, the power generation efficiency of the vibration dynamo device 10 can be improved, so that the light source 30 can emit light more easily.

(Embodiment 2)
The cane 5 of the second embodiment shown in FIG. 7 is basically the same as the cane 1 of the first embodiment, but differs in that an elastic member 42 is used instead of the magnet 40.

The elastic member 42 is disposed between the bottom of the main body 2 and the tubular member 11. Specifically, the elastic member 42 includes a lower end of the housing 14 and a plate-like member 41 disposed at the lower end of the main body 2. It is connected. The elastic member 42 supports the cylindrical member 11 elastically, and for example, a spring or the like is used.

When the cylindrical member 11 moves downward in the vertical reciprocation of the cylindrical member 11 accompanying the vertical movement of the main body 2 by using the cane 5, the elastic force of the elastic member 42 causes the cylindrical member 11 to move downward. Facilitates upward movement. For this reason, also in the cane 5 in the present embodiment, the power generation efficiency of the vibration dynamo device can be further improved, so that light can be emitted more easily.

(Embodiment 3)
The cane 6 of the third embodiment shown in FIGS. 8 and 9 is basically the same as the cane 1 of the first embodiment, but differs mainly in that the vibration dynamo device 10 is located at the upper end of the cane. .

As shown in FIGS. 8 and 9, the vibration dynamo device 10 including the cylindrical member 11 and the vibration member 20 is disposed in the upper end of the main body 2, that is, in the vicinity of the portion connected to the handle 3.

As shown in FIG. 8, a fixing member 7 is attached to the main body portion 2 so that the cylindrical member 11 does not move downward from a predetermined position. The fixing member 7 is a plate-like member extending in a direction intersecting with the extending direction of the main body 2, and for example, a stopper screw, a stopper pin, or the like is used.

In the present embodiment, a bottomed cup-shaped member 8 is disposed between the main body 2 and the housing 14. The cup-shaped member 8 is made of a nonmagnetic material, and is made of a resin such as polycarbonate, for example. The cup-shaped member 8 may be omitted.

An output electric wire 18 is connected to the rectifier circuit 15. The output electric wire 18 transmits the current generated by the vibration dynamo device 10.

The light source 30 emitted by the vibration dynamo device 10 is disposed in the vicinity of the handle 3 as shown in FIG. In FIG. 9, the light source 30 is attached to the rear end of the handle 3, but the installation location of the light source 30 is not limited, and may be the vicinity of the handle 3 (intersection) in the main body 2. The light source 30 may be an LED or the like, or a lighting device such as a flashlight.

Further, a switch 31 for switching the light source 30 on and off is disposed in the vicinity of the handle 3.

Since the light source 30 is attached so as to be exposed as shown in FIG. 9, the portion that accommodates the cylindrical member 11 in the main body 2 of the present embodiment may be non-translucent. Specifically, the main body 2 of the present embodiment is a metal cylindrical member.

Furthermore, as shown in FIG. 9, a solar panel 50 is disposed in the vicinity of the handle 3. A solar charging / light source lighting circuit 51 and a charging circuit 52 are accommodated inside the handle 3. The charging circuit 52 has a rechargeable battery, an electric double layer capacitor, etc., for example. In order to accommodate the solar charging / light source lighting circuit 51 and the charging circuit 52 inside, a lid 3 a is provided at one end of the handle 3.

The output wire 18, the switch 31, and the solar panel 50 are electrically connected to the solar charging / light source lighting circuit 51 and the charging circuit 52. The solar charging / light source lighting circuit 51 and the charging circuit 52 are electrically connected to the light source 30.

Subsequently, the operation of the cane 6 of the present embodiment will be described with reference to FIGS.

When the user uses the cane 6 as a walking aid, as in the first embodiment, the cylindrical member 11 housed inside the main body 2 moves in the vertical direction as the main body 2 moves in the vertical direction. The vibrating member 20 reciprocates along the extending direction (vertical direction) of the cylindrical member 11. As a result, the vibrating member 20 reciprocates in the coil 12 disposed on the outer periphery of the cylindrical member 11, so that an alternating current is generated in the coil 12. The alternating current generated in the coil 12 is transmitted to the rectifier circuit 15 connected to the coil 12, and the DC power source rectified by the rectifier circuit 15 is transmitted to the output electric wire 18 and charged in the charging circuit 52.

In addition, when there is daytime solar radiation, the current generated by the solar panel 50 is charged to the charging circuit 52 via the solar charging / light source lighting circuit 51.

When the light source 30 emits light, the switch 31 is turned on. Thereby, the light source 30 emits light by the current generated from the vibration dynamo device 10. Further, when the power generation amount of the vibration dynamo device 10 is small, a current is passed from the charging circuit 52 to the light source 30.

If the light source 30 does not emit light, the switch 31 is turned off. In this state, when the vibrating member 20 is reciprocated by using the cane 6, the current generated in the coil 12 can be charged to the charging circuit 52 via the rectifier circuit 15 as described above.

As described above, the cane 6 of the third embodiment further includes the handle 3 disposed at the upper end of the main body 2, and the light source 30 is disposed in the vicinity of the handle 3. The cane of the present invention may have a configuration in which the light source 30 is arranged at the upper end of the cane 6 as in the third embodiment.

Further, the cane 6 of the third embodiment further includes a solar panel 50 disposed in the vicinity of the handle 3. Thereby, it is possible to charge the charging circuit by the power generation of both the vibration dynamo device 10 and the solar panel, and to emit light when necessary. For this reason, the light source 30 can always emit light when dark.

(Embodiment 4)
The cane 9 of the fourth embodiment shown in FIG. 10 is basically the same as the cane 6 of the third embodiment, but differs in that an elastic member 42 is used instead of the magnet 40.

The elastic member 42 is disposed between the cup-shaped member 8 attached to the main body 2 and the lower end of the casing 14 that houses the cylindrical member 11. The elastic member 42 is, for example, a spring. In the reciprocating motion of the cylindrical member 11 in the vertical direction, when the cylindrical member 11 moves downward, the upward movement of the cylindrical member 11 is promoted by the elastic force of the elastic member 42. For this reason, also in the cane 9 in the present embodiment, the power generation efficiency of the vibration dynamo device can be further improved, so that light can be emitted more easily.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above-described embodiment but by the scope of claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
