Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to shoes with improved visibility at night or the like by providing a light emitting device.

[0002]

2. Description of the Related Art Conventionally, when a pedestrian goes out at night, a reflecting sheet that reflects light emitted from the vehicle or the like in order to notify a running vehicle or the like of the presence of the pedestrian and prevent an accident from occurring. Have been already developed and are known. However, since the reflection sheet is not a member that emits light, if the vehicle is not lit, or if the reflection sheet on the shoe is located in a blind spot with respect to the irradiation light, it reflects the irradiation light from the vehicle or the like. It has a drawback that it cannot be operated effectively. Therefore, as disclosed in Japanese Utility Model Laid-Open No. 6-19515 and Japanese Utility Model Laid-Open No. 6-52508, the present applicant has a light emitting diode as a self-luminous means, and the magnitude of the load applied to the switch when the switch is worn. Have been developed and produced shoes equipped with a light emitting device capable of emitting the light emitting diode. In addition, the present applicant is equipped with a vibration switch (a switch that is turned on and off by a change in the posture of the shoe or a vibration applied to the shoe) instead of the load switch as disclosed in Japanese Patent Application No. 7-163027. Proposes a new kind of shoe in which the light emitting diode emits light by the switch operation, and the unit case 30 is attached to the upper of the shoe as described in the specification and drawings of this patent application. At present, sports shoes in which a light-emitting unit (including a light-emitting diode 43 and the like) 40 housed in a case 30 and self-luminous by the operation of a vibration switch 45 are manufactured.

[0003]

In the above sports shoes, the light emitting unit 40 is equipped with, for example, three light emitting diodes 43... Mounted on a circuit board in the same vertical direction. As the unit case 30, a resin molded product having a transparent and smooth surface is used. However, the light emitting diode 43 generally has a property that light emitted from the light emitting diode 43 becomes light traveling in one direction mainly determined by the attitude of the light emitting diode. Therefore, a sports shoe equipped with a conventional light emitting device has a structure in which all light from the light emitting unit 40 is mainly emitted in one direction, that is, in a vertical direction, and proceeds directly through the inside of the unit case 30. Therefore, in one direction, high-brightness light can be easily recognized, but in the other direction,
There is a disadvantage that light emission can be visually recognized only insufficiently, and in severe cases, light emission can hardly be confirmed. in short,
Conventional shoes equipped with this type of light emitting device have a structure that should be further improved in visual recognition performance.

The present invention has been made in view of the above circumstances and has been made in order to solve the conventional drawbacks. An object of the present invention is to provide a light emitting device (light emitting unit) which emits light in various directions. Accordingly, it is an object of the present invention to provide a shoe provided with a light emitting device whose visibility has been significantly improved as compared with conventional shoes of the same kind.

In other words, the vibration switch 14 reliably performs the switch operation with high sensitivity when the wearer walks or runs, for example, particularly when the foot is moved (kick foot, foot foot) in the front-rear direction. In particular, since the vibration switch 14 includes two conductive steel balls 22, 22 in the switch case 21, these steel balls 22,
When the steel balls 22 are one due to the collision of the steel balls 22 with each other, the occurrence of a situation where the steel balls 22 are locked at a certain position in the switch case 21 and do not move is eliminated, and therefore, the vibration switch 14 becomes more operable. Smooth and stable switch operation is possible.

0c sequentially blinks, and the sequential blinking is repeated for three cycles, and the blinking time is about 1 in three cycles.
Relay circuit set to be seconds (not shown)
And a monostable multivibrator circuit (not shown) for preventing the light emitting device 10 from functioning even if the switch-on operation is performed again while the light-emitting device 10 is lit by one switching operation. Therefore, the light emission can be continued without interruption so that the light emitting portion appears to be moving in sequence between the three light emitters 10a to 10c. Further, since the lighting control circuit 16 is of a monostable multivibrator system, even if the continuous switch operation is irregular, regular blinking for light emission is maintained and unnecessary light emission is prevented. This can contribute to prolonging the battery life. Although not provided in the above embodiment, the lighting control circuit 16 includes an optical sensor such as CdS
When the optical sensor receives light of a predetermined amount or more, the light emitters 10a to 10c may be controlled to be turned off. With this configuration, when the surroundings are bright, for example, in the daytime, the light emitting devices 10a to 10c do not light up, and conversely, only when the surroundings are dark (for example, at night), the light emitting devices 10a to 10c can light up. ,
Therefore, power consumption is saved, and the life of the battery 13 is further extended.
