Attached shoes are already developed and known.
However, since the reflective sheet is not a self-luminous member, when the vehicle is unlit or when the reflective sheet on the shoe is located at a blind spot with respect to the irradiated light, the reflected light from the vehicle or the like is reflected. It was not possible and had the disadvantage of not functioning effectively.

Hereafter, each characteristic element of the shoes of this invention is demonstrated in order with the preferable aspect.
The light-emitting unit is integrally configured by mounting a light-emitting device (light-emitting diode, LED), battery, and vibration switch on a circuit board, and forming a lighting control circuit connected to these on the same board. .
In the shoe of the present invention, a plurality of light emitters (light emitting diodes) are mounted on the circuit board, and at least one of the plurality of light emitters is directed to another light emitting device. Provided differently from the orientation of the vessel. As an example of one light-emitting unit, at least one light-emitting device among a plurality of light-emitting devices is mounted in a horizontal orientation with respect to the circuit board, and the other light-emitting devices have a vertical orientation with respect to the circuit board. Mounted on. With this configuration, the light emitted from the light emitter has a plurality of directions.

On the circuit board of the light emitting unit, a lighting control circuit for controlling blinking operations of a plurality of light emitters is usually formed. More preferably, the lighting control circuit is provided with a relay circuit for sequentially blinking a plurality of light emitters. According to this configuration, it appears that the place where light is emitted moves sequentially between the plurality of light emitters.
Further, the above lighting control circuit is more preferably a monostable multivibrator system, and is configured not to operate depending on the operation of the vibration switch while the light emitter is turned on. According to this configuration, even if the continuous switch operation is irregular, regular blinking for light emission is maintained, and unnecessary light emission is prevented, thereby contributing to the extension of battery life. Furthermore, it is particularly preferable that the lighting control circuit of the above-described system is set to perform lighting control of a plurality of cycles, for example, 3 cycles, for example, for about one second by a single switch operation. According to this configuration, the light emission can be continued regularly without interruption, and the appearance can be beautiful.
More preferably, the lighting control circuit includes an optical sensor, for example, CdS, and is configured to control the light emitting device to be unlit by receiving light of the optical sensor. According to this configuration, when the surroundings are bright, for example, in the daytime, the light emitter is not turned on. On the other hand, only when the surroundings are dark, for example, only at night, the light emitting device is turned on. The life of the battery as a power source is further extended.

The battery is a power source for lighting the light emitter, and various batteries such as a manganese battery, an alkaline manganese battery, a lithium battery, a nickel-cadmium battery, and a nickel-hydrogen battery can be used as the battery. A small size and a large capacity are more preferable.
The vibration switch is a so-called vibration sensor type switch that opens and closes when vibration is applied. For example, the vibration switch is provided on the surface of the circuit board of the light emitting unit and covers the contact. The conductive switch case is mounted on the circuit board, and the conductive steel ball is accommodated in the switch case so as to be movable in the longitudinal direction, and the longitudinal direction of the switch case is kept substantially horizontal. Configured as follows. According to this configuration, the vibration switch reliably switches with high sensitivity when the wearer walks or runs, for example, by carrying the foot in the front-rear direction, and at the same time with low sensitivity depending on movement in other directions. It is possible to prevent the switch operation, so that the lighting sensitivity of the light emitting unit can be directional.
More preferably, in the vibration switch, when the conductive steel ball is located at one end or both ends in the longitudinal direction of the switch case or when located at the side in the width direction of the switch case, the contact and the switch case are electrically conductive. It is configured to be conducted through a steel ball. According to this configuration, the vibration switch is not only when the conductive steel ball is located at one end side or both end sides of the switch case, but always when the conductive steel ball contacts one of the inner surfaces of the switch case. Accordingly, stable switch operation is possible with respect to vibration or change in posture of the switch case.
More preferably, the vibration switch includes a plurality of conductive steel balls in the switch case. According to this configuration, since the conductive steel balls collide with each other, the situation where they are locked at a certain location in the switch case and cannot move is eliminated. Smoother and more stable.

  Further, in the shoe of the present invention, the light emitting device can be provided on the sole or the like. However, as a more preferable example, the light emitting device is mounted on a shoe upper by being held at a certain part by a holding means. The For example, the holding means is formed of a holding cover cloth mounted on the surface of the upper so as to press the periphery of the design case member. The holding cover cloth is made of, for example, a cloth material having an opening having a shape corresponding to the shape of the outer peripheral edge of the design case member. Attached to.

The design case member is a case member for housing the light emitting unit, and is attached to the upper of the shoe, for example, on the upper side of the shoe (of course, the light emitting unit is housed in the design case member). . The exterior design of the case member is completely free, such as a substantially bowl shape or a circle, and is usually determined in accordance with the consumer's hobby and fashion.
The design case member is made of a light transmissive material, for example, a transparent or translucent synthetic resin. Specific examples of the resin material include polyvinyl chloride resin, acrylic resin, polystyrene resin, and ABS resin. More preferably, the design case member is made of a polyvinyl chloride resin, and particularly preferably a semi-rigid polyvinyl chloride resin. Further, the design case member may be made of a resin composition that is made transparent by blending a transparent pigment, in addition to that made of a colorless and transparent resin.

And in the shoes of this invention, the uneven | corrugated rough surface (surface with an unevenness | corrugation) which produces irregular reflection of light about each site | part which the light from a some light emitter hits at least among the inner surfaces of a design case member It is preferable to be formed. With this configuration, the light emitted from the light emitter strikes the rough surface on the inner surface of the design case member, where light is irregularly reflected, and the reflected light travels in various directions. Accordingly, in the light emitting device of the present invention, the direction of the light emitted from the light emitter is in various directions combined with the fact that a plurality of light emitters are mounted. Is significantly improved.
The irregularities on the rough surface may be any shape as long as they cause irregular reflection of light, and may be regular shapes or irregular shapes. In other words, irregular irregularities are more preferable. Further, finer irregularities are more preferable.
Moreover, the above-mentioned rough surface portion can be formed by, for example, sand blasting, glass bead finishing or diamond cutting.
In the case of sandblasting, for example, the rough surface is finished with a density of # 15 to # 240, more preferably # 50 to # 200.
In the case of glass bead finishing, for example, a rough surface with a density of # 15 to # 240, more preferably # 50 to # 200 is finished.
And in the case of diamond cut finishing, for example, the depth of unevenness is 0.3 to 3.0 mm, more preferably 0.5 to 1.5 mm on an uneven rough surface, and the density is 5 to 600 dots / cm ² . Preferably, it is finished to an uneven rough surface of ^{20 to} 200 dots / cm ² .
When the above rough surface portion is formed within the above range relating to the density (in the case of diamond cut finish, the density and the depth of the unevenness), a higher effect is obtained for improving the visual performance. It is done. If it is within the more preferable range, a higher improvement effect can be obtained.
In a more preferable design case member, the convex lens portion is provided at a position corresponding to the light emitter (light emitting diode) in the housed state of the light emitting unit. According to this configuration, the light emitted from the light emitting unit spreads over a wider range, and the visual recognition performance is further enhanced.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the shoe of this embodiment is a sneaker for children, and the outer surface of the upper 1 has a substantially triangular shape and has a design imitating a state in which plasma is emitted. A light emitting device 2 is provided.
As shown in FIGS. 2 to 4, the light-emitting device 2 is configured by opening the design case member 3 on the upper surface side and housing the light-emitting unit 4 in the design case member 3. And it is hold | maintained in the specific site | part in the upper 1 by the holding cover cloth 5 as a holding means.
The holding cover cloth 5 is a cloth material generally called a blade part, and an opening 6 having a shape corresponding to the shape of the design case member 3 is formed at the center thereof. The design case member 3 is fitted into the opening 6, and the peripheral edge 9 of the design case member 3 is bonded to the back surface of the holding cover cloth 5.
Further, surface fasteners 8 a and 8 b are provided on the front surface of the upper base 7 and the rear surface of the holding cover cloth 5, respectively, so that the holding cover cloth 5 can be freely engaged with and disengaged from the upper 1.
Therefore, as shown in FIGS. 2 to 4, the light emitting unit 4 is housed in the design case member 3, and then the surface fastener 8a and the surface fastener 8b are engaged with each other, whereby the light emitting device 2 can be It is designed to be attached to the cover 1.
On the contrary, the light emitting unit 4 can be easily detached from the shoe upper 1 by releasing the engagement of the hook-and-loop fastener 8a and the hook-and-loop fastener 8b.

  As shown in detail in FIG. 5, the design case member 3 is a case member having a substantially triangular outer shape similar to a heel, and is made of a light-transmitting semi-rigid polyvinyl chloride resin. The material of the design case member 3 may be a colorless and transparent resin, or may be a resin composition that has been made transparent by blending a transparent pigment. The design case member 3 is not limited to being colorless, and can be colored in any color as long as light emitted from the light emitter 10 of the light emitting unit 4 can be transmitted. In FIG. 5, reference numeral 11 denotes a part of the design imitating the state of the source of plasma. Reference numeral 12 denotes an acute angle portion corresponding to a portion where plasma light strikes, and is filled with the above-described light-transmitting resin as shown in FIG.

Further, as shown in FIGS. 6 and 7, the light emitting unit 4 includes three light emitters (light emitting diodes, LEDs) 10 a, 10 b, 10 c, a lithium button battery 13, and a vibration switch 14 on a planar circuit board 15. The lighting control circuit (IC circuit) 16 that is mounted on and connected to these is formed at the corner of the circuit board 15, thereby being integrally formed. In the figure, reference numeral 17 denotes a presser for the lithium battery 13.
In this embodiment, among the three light emitters 10a, 10b, and 10c, the light emitter 10a is mounted in a direction perpendicular to the circuit board 15, but the other light emitters 10b, 10c is mounted in a horizontal direction with respect to the circuit board 15 and toward the acute angle portion 12. Thereby, there are three directions of light emitted from the light emitters 10a to 10c.
The light emission colors of the light emitters 10a to 10c are not particularly limited and can be arbitrarily selected. From the viewpoint of visual recognition performance, a red light emitting diode that emits light with high luminance is more preferable.

  Further, the design case member 3 is provided with a convex lens portion 18 at a position immediately above the light emitter 10a. More precisely, the light emitter 10a is arranged at a position corresponding to the central convex lens among a set of three convex lenses forming the convex lens portion 18, and the light emitter 10a corresponds to the convex lenses on both sides thereof. Not done. However, when the light emitter 10a is turned on and emits light from the central convex lens, the convex lens portions on both sides also shine more or less due to the scattered light, and it looks as if the light emitter 10a is provided inside.

And in this example, among the inner surface of the design case member 3, at least the uneven surface that causes irregular reflection of light for each portion that receives light from the three light emitters 10a, 10b, and 10c. 19 is formed. That is, of the inner surface of the cavity that houses the light emitting unit 4, each part of the inner surface of the acute angle portion 12 and the inner surface of the convex lens portion 18 is a surface with fine irregularities.
The uneven surface 19 is formed by, for example, sandblasting, glass bead finishing, or diamond cutting. For example, in the case of sandblast finishing, it is finished to a rough surface with a density of # 50 to # 200, and in the case of glass bead finishing, it is finished to a rough surface with a density of # 50 to # 200. In this case, the rough surface is finished to a depth of 0.5 to 1.5 mm and a density of 20 to 200 dots / cm ² .
Therefore, the light in different directions emitted from the three light emitters 10a, 10b, and 10c hits the uneven rough surface 19 on the inner surface of the design case member 3, and irregular reflection of the light occurs there. Will continue in various directions.
Therefore, in the shoes of this embodiment, the directions of light emitted from the light emitters 10a to 10c are in various directions, and the visual recognition performance is remarkably improved as compared with the conventional shoes.

8 and 9, the vibration switch 14 is provided with a strip-shaped contact 20 on the surface of the circuit board 15, and a box-shaped conductive switch case 21 is provided so as to cover the contact 20. The two conductive steel balls 22 and 22 are accommodated in the switch case 21 so as to be freely movable in the longitudinal direction thereof, and the longitudinal direction of the switch case 21 is kept almost horizontal. It is configured to lean.
Accordingly, when the conductive steel ball 22 is positioned at one end or both ends of the switch case 21 in the longitudinal direction, or when the conductive steel ball 22 is positioned at the end of the switch case 21 in the width direction, the contact 20 and the switch When the case 21 is connected to the case 21 via the conductive steel ball 22 and the steel ball 22 is located at the center of the switch case 21 in the longitudinal direction and is not in contact with the inner side surface of the switch case 21, The contact 20 and the switch case 21 are configured to be kept in a non-conductive state.
Therefore, the vibration switch 14 performs a stable switch operation against the vibration or posture change of the switch case 21. In other words, the vibration switch 14 is surely switched with high sensitivity when the wearer walks or runs, for example, by carrying the foot in the front-rear direction (kicking foot, landing).
In particular, since the vibration switch 14 includes two conductive steel balls 22 and 22 in the switch case 21, when the steel balls 22 and 22 collide with each other, Occurrence of the situation where it is locked at a certain position in the switch case 21 and stops moving does not occur, so that the vibration switch 14 can perform a smoother and more stable switch operation.

Further, the lighting control circuit 16 sequentially blinks the three light emitters 10a to 10c by the switching operation of the vibration switch 14, and repeats the sequential blinking for three cycles, and the blinking time is about three cycles. A monolithic circuit that does not function even if the switch-on operation is performed again while the light-emitting device 10 is turned on by a relay circuit (not shown) set to be 1 second and a single switch operation. A multivibrator circuit (not shown).
Therefore, it is possible to continue the light emission without interruption so that the place where the light is emitted appears to move sequentially between the three light emitters 10a to 10c. In addition, since the lighting control circuit 16 is a monostable multivibrator system, even if the continuous switch operation is irregular, regular flashing for light emission is maintained and unnecessary light emission is prevented. Thus, the battery life can be extended.
Although not provided in the above-described embodiment, the lighting control circuit 16 includes an optical sensor, for example, CdS. When the optical sensor receives light of a predetermined amount or more, the light emitting devices 10a to 10c are not turned on. It can also be configured to control. With this configuration, the light emitters 10a to 10c are not turned on when the surroundings are bright, for example, in the daytime, and on the contrary, the light emitters 10a to 10c can be turned on only when the surroundings are dark (for example, at night). Therefore, power consumption is saved and the life of the battery 13 is further extended.
