Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety umbrella, and more particularly, to a safety umbrella which allows other persons to clearly recognize the presence of the umbrella and the user of the umbrella when the umbrella is used outdoors.

[0002]

2. Description of the Related Art When an umbrella is used during a nighttime rain, it is difficult for a third party such as a car driver to recognize the existence of the umbrella and its user. In order to make a third party aware of the existence of the umbrella and its users during nighttime rain, an umbrella having a light emitting element such as a light emitting diode attached to the tip of each bone member of the umbrella cover has already been developed. (See Japanese Utility Model Laid-Open No. 58-62914).

[0003]

However, such a conventional umbrella has the following problems. (1) Since many light emitting elements are required, the cost is high. (2) Since a large number of light emitting elements are required, there is a high probability of occurrence of contact failure at the connection point between the light emitting element and the electric wire. (3) Since the light emitting element is provided at the tip of the bone member of the cover portion, the light emitting element is easily damaged.

An object of the present invention is to provide a safety umbrella which can be manufactured at a low cost and which is less likely to cause a failure.

The projection 63 is fitted into a hole formed in the peripheral portion of the hood member 22, so that the peripheral portion of the hood member 22 is attached to the tip portion of the bone member 21.

FIG. 6 shows an electric circuit and an optical circuit provided on the safety umbrella.

The circuit for light emission provided on the safety umbrella is
It comprises a power source 101 composed of dry batteries 41 and 42, a control circuit 102 provided on the circuit board 34, a switch 35, a light emitting diode 56, and a plurality of optical fibers 61. The dry batteries 41, 42 and the control circuit 102 are connected to the conductive plates 37, 3
It is connected by 8 and 39. The control circuit 102 and the light emitting diode 56 are connected by an electric wire 57.

The control circuit 102 controls the lighting mode of the light emitting diode 56. When the switch 35 is pressed once, the light emitting diode 56 continuously lights up. When the switch 35 is pressed twice, the light emitting diode 5
6 repeats lighting and extinguishing. That is, the light emitting diode 56 blinks. When the push button 35 is continuously pressed for a predetermined time or longer, the power is turned off.

When the light emitting diode 56 is turned on, the light is incident on the base end of each optical fiber 61. Optical fiber 6
The light incident on the base end of No. 1 travels inside the optical fiber 61 and is emitted from the tip of the optical fiber 61. Therefore, the tip of each optical fiber 61 emits light.

That is, in the above-mentioned safety umbrella, the light emitting diode 56 housed in the portion of the connecting member 13 projecting upward from the cover portion 2 lights up (or blinks), and is at the tip of each bone member 21. The tip of the optical fiber 61 lights (or blinks). Therefore, when this safety umbrella is used during nighttime rain, a third party can clearly recognize the presence of the safety umbrella and the user of the safety umbrella.

Further, since the number of light emitting elements such as light emitting diodes is smaller than that of the conventional umbrella with a warning light, the cost can be reduced. Moreover, since the number of light emitting elements is small, the probability of contact failure at the connection between each light emitting element and the electric wire is reduced. Further, unlike the conventional umbrella with a warning light, it is not necessary to provide the light emitting element at the tip of the bone member,
The light emitting element is less likely to be damaged.

Although one optical fiber is inserted in each bone member 21 in the drawings, an optical fiber bundle composed of a plurality of optical fibers may be inserted in each bone member 21.

[0026]

As described above, according to the present invention, it is possible to obtain a safety umbrella which can be manufactured at a low cost and which is less likely to cause a failure.
