SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, a vehicular lamp of the present invention has a cassette type lamp main body having an insertion opening at an upper end thereof and a storage box for accommodating the lamp main body in a replaceable manner. Is attached to the vehicle body on the inside of the vehicle, and irradiation ports are respectively opened in series on the front surface of the storage box and the vehicle body in front of the storage box, and a positioning mechanism for the lamp body is provided in the storage box, and A fitting portion to be fitted is provided on the lamp body.

It is preferable that the storage box is fixed to the vehicle body via an irradiation optical axis adjusting screw which is arranged at intervals in the left, right, up and down directions.

Further, as described in claim 3, it is preferable that a lock mechanism for both a hand and a hand is provided at an upper end of the lamp body, and a lock receiver engageable with the lock mechanism is provided at an upper end of the storage box. .

[0009]

According to the vehicular lamp of the above construction, when the bulb is cut or the lamp breaks down, the lamp main body is pulled up from the insertion opening at the upper end of the storage box, and another (no light bulb is broken or broken).
The lamp body can be inserted into the storage box from the insertion opening. When the lamp body is inserted into the storage box, the fitting portion of the lamp body automatically fits into the positioning mechanism on the storage box side, and the lamp body is mounted in a fixed position and in a fixed posture.
Therefore, not only can the lamp body be replaced quickly and easily, but also after the replacement, the position and orientation of the lamp body are always kept constant and the irradiation direction does not change.

According to the vehicle lamp of the second aspect, the direction of the lamp body (irradiation light) stored in the storage box can be arbitrarily adjusted by appropriately adjusting the irradiation optical axis adjusting screw. Also, once the adjustment is made, the direction of the irradiation light does not change even if the lamp body is replaced, and is always constant.

According to the vehicle lamp of the third aspect, the lamp main body can be carried with the handpiece at the upper end, and after the lamp main body is inserted into the storage box, the locking mechanism for both the handbag and the lock at the upper end of the storage box is provided. The lamp body can be securely fixed by engaging with the receiving member.

By rotating the nuts 6a and 6b of the irradiation optical axis adjusting screw 6, the distance between the screw 6 of the storage box 5 and the mounting plate 4 is adjusted, and the direction of the storage box 5 is changed. In FIG. 1, reference numeral 6e denotes a spherical washer, and 6f denotes a nut.

As shown in FIG. 1, the storage box 5 has a rear plate 5a inclined rearward and upward, the upper and lower ends open, and the upper end opening 5
b is formed in the insertion opening of the lamp body. Also, the front plate 5
An irradiation port 5d is opened in c as shown in FIG. Further, a positioning tool 5f for the front leg 7k (FIG. 3) on the bottom surface of the lamp body 7 is formed at the front end of the lower opening 5e. The shape of the irradiation port 5d matches the shape of the mounting plate 4 in the frame.

At the center of the upper end of the front plate 5c, a lock receiver 5g is mounted as shown in FIG. 2, and when the lamp body 7 is inserted into the storage box 5, a lock mechanism 7h described later is turned clockwise. When it is rotated (FIG. 2), it engages with the lock receiver 5g. Near the center of the upper end of both side plates 5h of the storage box 5,
As shown in FIG. 2, guide plates 5i whose upper ends are bent outward are fixed with stoppers.

As shown in FIG. 3 and FIG.
Is a cassette type which can be exchanged and carried, and can be inserted into the storage box 5 from an upper end opening 5b (FIG. 1). Then, in the inserted state, the rear plate 7 of the lamp body 7 can be attached to the lower inclined surface of the rear plate 5a so that the lamp body 7 is held at a fixed position in the storage box 5 in a fixed posture.
The lower part 7b of a is inclined as shown in FIG. The front leg 7k of the lamp body 7 and its positioning tool 5f also function as a positioning mechanism for holding the lamp body 7 at a fixed position in the storage box 5 in a fixed posture and a fitting portion thereof.

The interior of the lamp body 7 is vertically divided by a partition plate 7c, and a headlight 8 is provided at an upper portion and a tail light 9 is provided at a lower portion. A headlight 8 is provided on the upper part of the front plate 7d of the lamp body 7.
Irradiation port 7e for tail light 9 is opened at the lower part, respectively.

On the upper surface of the lamp body 7, a connector 7g is provided on the left side as shown in FIG.
Are arranged respectively. The rear plate 7a is separated so as to be detachable from the lamp body 7, the lower end of the rear plate 7a is rotatably attached to the bottom surface of the lamp body 7 by a pair of removable butterfly plates 7i, and the upper end of the rear plate 7a is paired. The spring catch 7j is connected to the upper surface of the lamp body 7. Further, as shown in FIG.
k, 7l are protruded.

The headlight 8 has a substantially hemispherical shape with an open front, and a light bulb 8b such as a halogen bulb is detachably attached to the center of the rear surface 8a as shown in FIG. The rear surface 8a is coated with a reflective material so as to reflect the light emitted from the bulb 8b forward. Headlight 8
A transparent glass plate 8c or a lens is attached to the opening on the front surface of the lens.

A frame-like mounting member 8d as shown in FIG. 4 is fixed around the front end of the headlight 8, and mounting holes 8e are formed at four positions of the mounting member 8d. I have. Then, as shown in FIG. 6, the headlight 8 is fixed to the front plate 7d in the lamp body 7 with the bolts 8f penetrating through the mounting holes 8e after the rubber dampers 8g are interposed before and after the mounting member 8d. It is fastened and fixed to the set nut 7m. With this structure, the headlight 8 is supported by the lamp body 7 in a vibration-proof manner.

The taillight 9 has a light bulb 9c mounted on a socket 9b on two socket bases 9a arranged side by side as shown in FIG. A common red lens 9d is arranged in front of the bulb 9c as shown in FIG.

As shown in FIG. 3, the electric wire 10 is connected to the bulb 8b of the headlight 8 and the electric wire 11 is connected to the bulb 9c of the taillight 9 from the connector 7g. The electric wire 11 on the tail light 9 side is guided through the rubber bush 12 of the partition plate 7c.

In the railway vehicle lighting device according to the present embodiment having the above-described configuration, a spare cassette-type lighting device body 7 is mounted on a vehicle, and when the light bulbs 8b and 9c are cut off or the lighting device body 7 breaks down. At times, the lamp body 7 in the storage box 5 is taken out and replaced. When the lamp body 7 is taken out, the lock mechanism 7h is rotated counterclockwise (FIG. 2) to release the engagement with the lock receiver 5g, and then the handhold of the lock 7h is pulled up by hand. Just do it. The spare lamp body 7 is fixed in a fixed position in the storage box 5 in a reverse manner to the removal. At this time, the inclined surface of the rear plate 5a of the storage box 5, the inclined surface of the lower part 7b of the rear plate 7a of the lamp body 7, the positioning tool 5f of the storage box 5, and the front leg 7k of the lamp body 7 are as described above. It acts as a positioning mechanism and its fitting part.

Further, since the lamp body 7 of the present embodiment has the headlight 8 and the taillight 9 at the same time, it is disposed before and after the vehicle, and depending on the direction of the vehicle, either the headlight 8 or the taillight 9 is provided. Use with one of them lit. However, the invention is not limited to the embodiment. For example, only the headlight 8 may be provided in the lamp body 7.
