Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a light emitting device (LE)
D) It belongs to a light emitting device mechanism of an umbrella with a light emitting device using an optical fiber and a specific manufacturing method thereof.

[0002]

2. Description of the Related Art A conventional umbrella with a light emitting device is an umbrella with a light emitting element comprising a light emitting element disposed at each end of an umbrella bone, a built-in umbrella handle, and power supply means for supplying power to the light emitting element. .
(See Japanese Patent Application Laid-Open No. 04-5906) In this case, in order to emit light, a light source is required for each light emitting portion. Light emitting elements and power for causing them to emit light must be supplied. Also, in the case of using an optical fiber, a power supply accommodating portion, a power supply opening / closing switch, and a luminous body by the power supply are provided in the center rod, a lighting display unit is provided at the tip of a plurality of umbrella bones, and the luminous body and the lighting display unit are provided. A transmission line composed of an optical fiber between them is provided along the umbrella bone, a power supply accommodating section and a power supply open / close switch are provided in the middle rod, and a lighting display section composed of a luminous body is provided at the tip of a plurality of umbrella bones. And a metal transmission line between the power storage unit and the lighting display unit is provided along the umbrella bone. (Japanese Patent Laid-Open No. 08-29
4408) However, in the case of an umbrella having a light emitting device using an optical fiber represented by this case, in the establishment of the case,
In most cases, the bending resistance of the optical fiber is not taken into account. In particular, the hinge portion between the ribs in contact with the upper wheel has an unrealizable structure that exceeds the bending resistance of the optical fiber and breaks. Further, the method of introducing light into the optical fiber is uncertain, and sufficient illuminance and luminance that can be used practically cannot be obtained.

[0003]

In a conventional umbrella with a light-emitting device, a light source is set for each light-emitting portion. Due to the large number of light sources, the manufacturing cost is high, and the light source is cut off during the manufacturing process and distribution stage. Also, it is not feasible as a stable commercial product due to leakage due to rain or the like. Also, even in projects using optical fibers, there are no designs that can withstand practical use after securing sufficient light intensity and brightness, and most of them are structural plans that ignore the bending resistance, which is a material property of optical fibers. In particular, the light emitting device of the existing case mechanism cannot be realized because the optical fiber breaks at the hinge portion when passing from the upper wheel to the rib.

[0004] It is an object of the present invention to stably emit light from the entire inner rod and all the dew points with a light source as small as possible and to endure as a commercial product.

[0005]

In order to achieve the above object, a power supply, a light emitting element lighting circuit, a power on / off switch, and a light emitting element for light emission of a middle rod are arranged inside the grip. A lead wire to be installed on the center rod is installed, and it is connected to a light-emitting element that emits light at the tip of the stone, which is installed in the wheel.

[0006] Each of the ribs branches from the light emitting element for exposure to light.
The resin-based optical fiber to be installed is installed so that the end faces of the optical fiber are aligned and aligned with the optical axis of the light emitting element. The facing tip is processed into a spherical shape. At this time, the light emitting element installed in the stone ram and the upper wheel is not fixed. In addition, a long groove-shaped opening from the upper wheel to the center rod so that the optical fiber that is branched from the upper wheel and can be opened and closed with a curvature (R50 or more) that does not exceed the bending resistance of the optical fiber installed inside the rib. Is provided.

The inner rod is made of a permeable resin tube having as high a hardness and rupture resistance as possible, and its inner surface layer is subjected to satin finish.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A light emitting circuit board 14, a power supply on / off switch 15, a light emitting element-b13, and a dry battery 16 are installed inside a grip 4 shown in FIG. A high elastic resin or rubber is used for the grip lid 5. Further, the inner rod 2 connected to the inner rod 2 is made of a permeable resin tube, and the inner surface thereof is provided with a lead wire 12 which is subjected to a satin finish and is led to the light emitting element-b8.

[0009] A groove-shaped hole is formed in each of the ribs 3 on the stone foot / top wheel 1 shown in FIG. A tubular space is provided in the stone wheel / upper wheel 1, and the light emitting element-b8 is stored without being fixed.
The light emitting element-b8 to the optical fiber 10 are fixed by the heat-shrinkable material 8. Further, the optical fiber 10 is guided from the above-mentioned groove-shaped hole and installed in the groove of each rib 3. The optical fiber 10 and the rib 3 are fixed using the fixing spring 17. In addition, the stone shovel / upper wheel 1 and the inner rod 2 are fixed and reinforced by a metal fixing ring.

As shown in FIG. 4, the optical fiber 10 installed in the rib 3 is temporarily exposed to the outside at the joint with the small bone 6 which cannot be installed inside. The exposure at this time is positioned and fixed at a distance in consideration of the bending resistance of the optical fiber 10, and a spring 17 is used for fixing.

The tip 7 shown in FIG. 5 is made of a transparent resin, and is provided with an umbrella cloth fixing groove 18 so that the spelling thread for fixing the cloth can be fixed without penetrating the center of the tip, and the tip is machined into a spherical surface. Install so that the optical fiber reaches the position in the figure.

[0012]

Since the present invention is configured as described above, it has the following effects.

By using a transparent resin for the center rod and performing a satin finish on the inner surface layer thereof, and using an ultra-high brightness light emitting element, the entire center rod can emit light.

By installing a light emitting element for light emission at the tip of the stone in the inner space of the wheel so that the optical axis of the light emitting element is aligned with the end face of the optical fiber to be installed in the rib, the light can be efficiently emitted from the light source. .

The light emitting element for exposure light emission is installed without being fixed, and the passage of the optical fiber from the stone foot and the upper wheel to the ribs is made to pass through a long groove-shaped opening hole, so that an appropriate play is provided. The optical fiber does not break due to the curvature exceeding its bending resistance even when the umbrella is opened and closed.

The optical fiber is fixed to the rib by using a small-diameter spring. The optical fiber can be reliably fixed at a low cost without damaging the optical fiber, and the path of the optical fiber can be easily determined even at the connection between the rib and the rib. it can. In addition, when the umbrella is stored, the spring comes into contact between the ribs and the small bones, and an appropriate space is generated, so that the breakage of the optical fiber due to the contact of the bones is prevented.

By arranging the electric materials in the grip portion in a concentrated manner, it is possible to surely perform the waterproof treatment under daily use.
