Description

Light fitting for shoes

The present invention relates to a light fitting for shoes that causes a light to rise and glow with no power supply in walking and running operations, and causes the light around the shoes to emit light for visual recognition.

Heretofore, a number of proposals have been made for shoes that are provided with a light emitting device so that light is emitted around the shoes to make the presence visible. For example, as a shoe in which a battery serving as a power source is provided in the shoe and the LED and the like are illuminated by electricity supplied by the battery, Japanese Patent Application Laid-Open No. 2005-13314, Registered Utility Model 3038468, Registered Utility Model 3047473, Japanese Patent Application Laid-Open No. 8- Japanese Patent Publication No. 33210, Japanese Patent Publication No. 11-32813, etc. have been proposed. However, as a problem common to them, it is very difficult to incorporate and manufacture a light emitting device incorporating a battery in a shoe, and for that purpose, for example, the light emitting device is incorporated in a shoe and the problem of storage space, considerable cost in manufacturing There is a problem that becomes high, a problem that you can not wash shoes, a problem that you have to replace the battery because it does not emit light when the battery is exhausted, etc. If you wear your shoes, you have to buy the same shoes again to make them glow. Further, as a structural problem, there is also a problem that the light emitting shoe of the prior art can only be lighted in one direction.

Further, as a shoe in which a piezoelectric element is provided in the shoe and generated by the piezoelectric element to emit light, Japanese Patent Application No. 2000-022621, Japanese Patent Application Laid-Open No. 8-168272, Japanese Patent Application Laid-Open No. 5-504283, Japanese Patent Application Laid-Open No. 6- No. 209807, JP-A 2001-308405, JP-A 2005-183275, JP-A 2006-107859, etc. are proposed, and their respective configurations, generation methods and problems are summarized in Table 1. ing. As a problem common to them, since all configurations are also configured to provide the light emitting devices of the piezoelectric element and the light emitter in the shoe, it is very difficult to manufacture either, and in the structure as well, the light emitter is outside the shoe. The direction of light emission is fixed in one direction (back, side, or front at the bottom of the shoe) to emit light.

The light fitting of the shoe of the present invention can be produced by placing the electromotive section on the sole of the shoe in any narrow shoe, and can be detached from the shoe by means of fasteners without processing any existing shoes It can be fixed and mounted. And since the light mounting tool of the shoe of the present invention can be worn on the portion of the shoe desired by the person wearing it, the illumination direction of the LED can be arbitrarily set from the side to the rear at the portion to be worn. The direction can be made to light and be visible to the person in the range between the side and the back. In particular, if the present invention is worn 45 degrees diagonally backward, it is possible to simultaneously view all persons on the side and the rear of the shoe. And even if you change your shoes, you can use it permanently with no power forever. In addition, since the electromotive unit of the present invention can be appropriately bent in proportion to the magnitude of the pressure or impact from above without being bulky, a cushion that absorbs the force and cushions the impact.

It may be applied in size, and the other fastening materials 4b may be engaged with the fastening materials 4b. With this configuration, the position at which the fixing member 4b is fixed can be changed somewhat depending on the size of one of the fixing members 4b, and the light emitting position of the LED 6 can be appropriately changed and fixed. Here, as the

As another example, the fixing tool 4 may be configured with an adhesive applied in advance on the surface of the wiring member 3.

FIG. 3 shows each example of the configuration of the electromotive unit 2 constituting the “light fitting for shoes” of the present invention. The electromotive unit 2 constituting the "light fitting for shoes" is a piezoelectric electromotive unit 2A as a flat plate-like configuration that generates electricity, and the piezoelectric electromotive unit 2A is implemented by the configuration shown in FIG. The configuration of the piezoelectric electromotive portion 2A will now be described in detail. The piezoelectric electromotive part 2A constituting the present invention is constituted by a flat substrate 2a of a suitable thickness and flexibility and preferably made of a metal plate, and the appropriate size and thickness provided on the surface of the substrate 2a And the electrode surface 2c provided on the upper surface of the piezoelectric body 2b. Generally, a piezoelectric ceramic piezoelectric body is not elastic and is broken by a strong impact or bending, but by forming the piezoelectric ceramic in a flat thin shape, the flat thin piezoelectric ceramic has elasticity to some extent. It can be bent without cracking to some extent. Therefore, by providing the piezoelectric body 2b made of piezoelectric ceramic in a flat thin shape on the substrate 2a made of a flat and flexible metal plate in the structure shown in FIG. 8, the range in which the piezoelectric body 2b is not broken It can be bent inside to generate electricity. Therefore, the piezoelectric electromotive portion 2A constituting the present invention is appropriately bent without being broken by being constituted by the flexible substrate 2a and the piezoelectric member 2b provided flatly on the surface thereof. The structure can be very flat and thin, and can be suitably bent in proportion to the magnitude of the force against pressure and impact from above without being bulky, and the force absorbed is the impact Since it can serve as a cushion for relieving pain, it can be implemented without discomfort even if it is provided in the shoe. As an embodiment of the present invention, the substrate 2a constituting the piezoelectric electromotive portion 2A can be made of a metal or the like having a suitable thickness and flexibility, and as an embodiment, 42 ALLOY or the like made of brass, aluminum, copper, or an alloy Can be implemented by Alternatively, the substrate 2a may be formed by vapor deposition of aluminum on the surface of a thin plastic material, or conductive carbon or the like may be formed into a film. Further, the entire substrate 2a may be formed of conductive rubber or a conductive plastic material. The thickness of the substrate 2a may be a thickness that can be appropriately bent and has flexibility, and when it is formed of a metal plate, although depending on the material of the metal as an example, it is from 2 to 1 mm or less as an example It is even more preferable if it is 0.5 to 0.3 mm or less and 0.2 mm or less. The piezoelectric body 2b is obtained by sintering and polarizing barium titanate (BaTiO ₃ ), lead titanate, lead niobate, lithium niobate, etc. in addition to lead zirconate titanate (PZT) as a piezoelectric ceramic. The embodiment can be implemented with a thickness of 0.2 to 0.06 mm as an example. The piezoelectric film can be implemented by using film-like polyvinylidene fluoride (PVDF) or the like. By applying pressure to any substance, an electric polarization occurs in the substance to generate an electromotive current.

Each Example of the electromotive part 2 which comprises "the optical mounting tool of shoes" of this invention with FIG. 3 is described in order. FIG. 3A shows a configuration in which the electromotive unit 2 includes only the piezoelectric electromotive unit 2A. The structure of the piezoelectric electromotive portion 2A is as described above, and each core wire exposed at the tip of the wiring member 3 is connected to the surface of the substrate 2a and the flexible electrode plate 2B by soldering or the like. The surface of the connected electrode plate 2B and the electrode surface 2c of the piezoelectric body 2b are configured to be in contact with each other. In the configuration of FIG. 3 (a), even if it is placed on the sole as shown in FIG. 5, since the sole has some elasticity originally, the substrate 2a and the electrode plate 2B are flexible. Can absorb the load received from the crucible and deform appropriately, and the piezoelectric body 2b can be appropriately distorted to follow the bending deformation to generate electricity, and the present invention can be practiced with this configuration . Incidentally, instead of connecting one core wire of the wiring member 3 to the electrode plate 2B by soldering or the like, one core wire of the wiring member 3 is directly connected to the electrode surface 2c of the piezoelectric body 2b by soldering. It may be implemented as well. FIG. 3 (b) is configured by superposing an elastic overlay 2D on the configuration shown in FIG. 3 (a). With this configuration, the load received from the heel can be further absorbed by the elastic overlay 2D, so that even in a state of being actually placed and worn in a shoe, it can be implemented without discomfort. In FIG. 3 (c), an elastic underlayment 2E is further superimposed below the configuration shown in FIG. 3 (b), and the electrode plate 2B is soldered onto the underlayment 2E. It is connected and configured. With this configuration, the load applied to the heel can be absorbed further by the elastic upper sheet 2D and the lower sheet 2E. Therefore, even when the user actually wears a shoe, there is no sense of incongruity, and a more comfortable feeling can be obtained. The elastic overlays 2D and underlays 2E can be made of rubber, foamed plastic or the like, and the thickness thereof can be, for example, about 0.5 to 2 mm. In the configuration shown in FIG. 3B, instead of providing the overlay 2D, only the underlay 2E may be provided below the substrate 2a. In FIG. 3D, the upper sheet 2D and the lower sheet 2E are formed of conductive rubber. Since the conductive rubber has elasticity and conductivity, the respective core wires of the wiring material 3 are connected to the upper sheet 2D and the lower sheet 2E made of the conductive rubber, and the piezoelectric electromotive portion 2A is sandwiched by the upper sheet 2D and the lower sheet 2E. By sandwiching, the upper surface of the underlayment 2E and the lower surface of the substrate 2a are in contact with each other to be in the conductive state, and similarly the lower surface of the overlay 2D and the electrode surface 2c of the piezoelectric body 2b are in contact and in the conductive state. Since it is possible to conduct electricity directly from the upper sheet 2D and the lower sheet 2E, the process such as soldering can be eliminated and the manufacture can be extremely simplified. In addition, in order to make the upper sheet 2D and the lower sheet 2E mutually insulated with this configuration, a doughnut-shaped insulating material 2C made of a paper slightly larger than that is provided as shown in the figure. By the insulating material 2C, only the lower surface of the overlay 2D and the electrode surface 2c come into electrical conduction from the portion opened at the center thereof. In the configuration of each electromotive unit 2, each piezoelectric electromotive unit 2A is turned upside down so that the piezoelectric body 2b and the electrode surface 2c are directed downward and the substrate 2a is directed upward, as shown in FIG. The configuration of each of the electromotive units 2 shown in FIGS. Further, the outer shape of the electromotive unit 2 constituting the present invention is not limited to the substantially circular shape shown in the embodiment but may be a square shape, or may be formed with a large insole size. Further, the position of the electromotive unit 2 provided in the shoe is not limited to the position where the heel abuts, and may be provided so as to abut between the arch and the toes. Further, since the present invention can also be mounted on sandals and slippers, the "light fitting for shoes" of the present invention also includes sandals, slippers, and the like.

FIG. 7 shows the electromotive principle of the present invention. FIG. 7 (a) shows the principle of generation of electricity by the piezoelectric electromotive part 2A, and FIGS. 7 (b) to 7 (e) show the principle of generation of electricity by the electromotive part 2 shown in FIG. 3 (d). is there. In FIG. 7A, when a pressure indicated by a downward arrow is applied to the piezoelectric body 2b provided on the substrate 2a, distortion of bending occurs in the piezoelectric body 2b, and at the same time, the piezoelectric body 2b generates an electromotive force i (← ) To cause the LED 6a to emit light. Next, when the distorted pressure is removed, the flexible property of the substrate 2a returns to the original shape, and following it, the piezoelectric member 2b also returns to the original shape, and at the same time the electromotive current i →) is generated to make the LED 6 b emit light. By this principle of electromotive force, as shown in FIG. 5 (b), when walking or running in shoes, as shown in FIG. 7 (b) (c), weight (load) received from heels every time the foot is lowered As a result, a load shown by the downward arrow due to the weight is applied to the piezoelectric electromotive part 2A, and a distortion occurs in which the substrate 2a and the piezoelectric body 2b are slightly bent outward, and the deformation of the distortion causes the piezoelectric body 2b to rise. Generate an electromotive current i (←). Then, the LED 6a is lit and emits light due to the electromotive current i (←). Next, as shown in FIGS. 7 (d) and 7 (e), lifting the foot once lowered to the ground eliminates the load applied from the heel and removes the pressure applied to the substrate 2a. The flexible substrate 2a returns to its original shape by its own force, and the piezoelectric body 2b returns to its original shape following the substrate 2a, and the electromotive current i (→) is generated to turn on the LED 6b to emit light. Do. For this reason, during the operation of lowering and raising the foot, a voltage rise occurs twice, and the LED 6a and the LED 6b alternately light and emit light each time the voltage rises. Therefore, if, for example, the LED 6a is formed of a red LED and the LED 6b is formed of a green LED, it can be made visible to people around by the bi-colored light emission alternately, and a considerable alerting effect can be obtained. Further, for example, two fixtures 4 are prepared, and the LED 6a is fixed in the Z direction with one fixture 4 in the state of FIG. 4C, and the LED 6b is made in the X direction with another fixture 4. If it fixes facing, it can be made to emit light simultaneously to the back and the side with one electromotive part 2, and it can be made visible to people around.

FIG. 9 shows a configuration of the electromotive unit 2 shown in FIG. 3 in which the piezoelectric body 2b integral with the substrate 2a is largely bent when the foot is lowered to obtain a large amount of electromotive force. In FIGS. 9 (a), (b) and (c) of that embodiment, two arc-shaped insertion plates 2F are appropriately separated and parallel between the lower surface of the substrate 2a and the upper surface of the base 2E as shown. Intervened in the In this configuration, if the foot is stepped down, there is a gap between the substrate 2a and the underlay 2E as shown in the figure, so the substrate 2a is largely bent by the gap and at the same time the integral piezoelectric member 2b is also greatly bent. An electromotive amount is obtained. 9 (d), (e) and (f) of another embodiment, two bow-shaped insertion plates 2F are suitably separated as shown in the figure between the lower surface of the underlayment 2E and the upper surface of the shoe 7. It is configured to be interposed in parallel. In this configuration, when the foot is stepped down, there is a gap between the underlayment 2E and the shoe 7 as shown in the figure, so the underlayment 2E and the substrate 2a placed thereon are largely bent, and at the same time the piezoelectric body Since 2b is also greatly bent, a large electromotive force can be obtained. The thickness of the insertion plate 2F interposed here can be, for example, about 0.5 mm to 1.0 mm. Further, in the configuration of FIGS. 9 (d), (e) and (f), the left and right two sheets of the insertion plate 2F may be connected by a plate (not shown) connecting the two integrally.

FIG. 10 shows the construction of another embodiment of the method of mounting on a shoe according to the "shoe mounting tool" of the present invention shown in FIG. The wiring member 3 for conducting electricity generated by the electromotive unit 2 is constituted by a fixed wiring member 3A made of a metal which is suitably hard, rigid and bent. The properties of metal are rigidity and flexibility, and once bent it has the property of retaining its shape by its rigidity. Therefore, even if the wiring member 3 shown in the previous embodiment is not attached to the shoe by the fixing tool 4, by configuring the fixed wiring member 3A made of metal having appropriate rigidity and flexibility as the wiring member 3 to be energized The fixed wiring member 3A can be bent and sandwiched and fixed to the edge of the shoe according to the present invention. As a method of fixing to the shoe by the fixed wiring member 3A, the fixed wiring member 3A in a straight shape may be bent in advance in accordance with the edge of the shoe, and may be fixed by being pinched or bent in advance into a clip shape The fixed wiring member 3A may be sandwiched and fixed to the edge of the shoe. The fixed wiring member 3A can play a dual role of conducting electricity generated by the electromotive part 2 and of holding and fixing it on the edge of the shoe. As a configuration of the embodiment, the whole of the wiring member 3 to be energized may be configured by the fixed wiring member 3A, or only a portion fixed to the edge of the shoe may be configured by the fixed wiring member 3A. As a metal material for forming the fixed wiring member 3A, an iron material or the like which is suitably rigid and bent as an example can be used, and the shape is preferably a strip-like flat thin shape as illustrated, but the cross section is round It may be linear. In the configuration of the present embodiment, the connector 10 is provided at the tip of the fixed wiring member 3A, and can be inserted into and removed from the connector 10 shown in FIG.

FIG. 11 shows the configuration of an embodiment of the present invention in which light is emitted in a planar manner on the rear surface or side surface of the shoe. A light transmitting resin such as an acrylic material, a silicon material, or a vinyl chloride material has a light guiding property, and light incident in the resin repeats reflection and diffusion in the resin and becomes uniform light in the resin. It has the property of making the entire resin glow. The configuration shown in FIG. 11 actually shows a configuration in which the logo of the shoe is illuminated in a plane, and the connector provided on the wiring member 3 to be energized from the electromotive unit 2 shown in FIG. 10 or the fixed wiring member 3A. 11, the wiring member 3 can be connected by inserting and removing the connector 10. When the connector 10 is connected and the foot is stepped down, the LED 6 emits light by the electricity generated by the electromotive unit 2. The light emitted from the LED 6 is incident on the light guiding type surface light emitting portion 9b of the surface light emitting portion 9 formed of the light transmitting resin, and the incident light is reflected and diffused in the resin formed in the desired surface shape To repeat, it is possible to illuminate the desired surface shape. As a light guide type surface emitting unit 9b showing a glowing shoe company, in FIG. 11, the logo mark of Puma, Nike and New Balance is illuminated. The light guide type surface light emitting unit 9b formed in a desired surface shape can be attached to the rear surface or the side surface of the shoe with a surface fastener (magic tape (registered trademark)) or the like.

FIG. 12 shows the construction of another embodiment for making desired letters and surface light shine, and it is composed of a shielding type surface light emission portion 9a which is shielded by the filter 12 as the surface light emission portion 9 and which makes its opening emit light. It is If desired letters and planar openings are formed in the filter 12 in advance, and light is emitted from the rear of the filter 12 with the LED 6 (not shown), the light passes only through the formed apertures, so the desired letters and planar portions You can see only the light.

FIG. 13 shows a configuration in which light is guided by the light guide fiber 11, and light is made incident and guided in the light guide type surface light emitting section 9b. When the light of the LED 6 emitted by electricity generated by the electricity generation unit 2 is made to enter the light guiding fiber 11, the incident light is repeatedly reflected and diffused in the light guiding fiber 11, and is transmitted in the light guiding type surface light emitting unit 9b. It is incident on. Since the incident light is repeatedly reflected and diffused in the light guide type surface light emitting section 9b, it can be made to have a desired surface shape as in the embodiment shown in FIG. The light guiding fiber 11 is formed of a material that is appropriately bent, and the light of the LED 6 emitted and emitted by the electromotive unit 2 provided in the shoe is made to enter the light guiding fiber 11, and the light guiding fiber 11 It is possible to guide the incident light out of the shoe.

In the configuration of each embodiment, a cover may be provided to cover the LED 6 to diffuse the light emission, and by providing the cover, light emission that emits in the form of dots can be emitted to make the surface emit light. In the light can be lit with a gentle and not tired light. In the present invention, a pedometer function may be provided to detect an electric signal of an electromotive current generated by the electromotive unit 2 and measure the number of steps by the electric signal. For example, a button battery may be used as a power source of the pedometer function. However, since the consumption of the battery can be consumed only by detecting and displaying the electric signal, and the supply for emitting the light of the LED 6 is not required at all, the life can be considerably extended. Moreover, the convex part which stimulates the sole of a foot may be formed and comprised in said overlay 2D. As described above, in the case of the "light fitting for shoes" of the present invention, the piezoelectric body is mounted on any existing shoes and exercised by stepping on the flat plate-like electromotive unit 2 placed in the shoes.
