Description

[Detailed Description of the Invention] This invention relates to a simple sign light without a switch used as a road sign light, etc., and particularly to one using a Swan-type miniature light bulb.

As is well known, simple type marker lights are widely used as road sign lights, etc., in which the battery case itself constitutes the marker light and is disposable when the battery capacity runs out.

For this type of marker light, it is important to provide it at a low cost without sacrificing the minimum necessary functionality, and unlike general portable electric lights, it is not equipped with a switch.

In other words, this is a very simple structure in which multiple unfinished cells are housed in a cylindrical case, a socket is provided at one end of the case, and a miniature light bulb is attached to this socket. Species beacon lights are constructed.

There are two types of indicator lights of this type: those that use screw-type miniature bulbs and those that use swan-type miniature bulbs.

When using a screw-type miniature light bulb, it is possible to turn off the light by untwisting the miniature bulb to a certain extent, and the miniature bulb can be held almost stably in this state.

In other words, the rotation of the miniature light bulb can perform the same function as a switch, which is a major advantage of the screw type.

However, with screw-type bulbs, the miniature bulb screwed into the socket tends to loosen due to vibration or shock and turn off, and it is very troublesome to screw in the miniature bulb while wearing gloves, so do not screw it in too hard. However, there are drawbacks such as the socket side also rotating and causing internal wire breakage.

On the other hand, a marker light using a swan type miniature light bulb has the advantage that the miniature light bulb can be correctly installed with a small rotation angle and does not come loose due to vibration or impact.

However, when temporarily turning off a miniature light bulb, the swan type socket cannot hold the miniature light bulb in the unlit state, so the miniature bulb must be completely removed and stored elsewhere. There is the inconvenience of having to reinstall the miniature light bulb into the socket when it turns on.

When a large number of marker lights are turned on at night at a construction site and turned off in the morning, it is extremely inconvenient to have to remove the miniature light bulbs one by one, collect them, and store them in another suitable location. That's true.

This idea was devised in view of the conventional problems mentioned above, and its purpose was to make it possible to easily hold the miniature light bulb in the Swan type socket even when the light is turned off, in a marker light that uses a Swan type miniature bulb. The goal is to provide a beacon light with a high level of quality.

Hereinafter, embodiments of this invention will be described in detail based on the drawings.

FIG. 1 shows the overall configuration of a marker light according to this invention.

The case of this marker light has roll locking parts 1a on both the upper and lower ends.
It is composed of an exterior cylindrical body 1 having a diameter of 1b, a bottom plate 2, and a socket plate 3, and two unit cells 4a, 4b are installed inside this.
are connected in series through an intermediate insulating paper 5 and a lead wire 6a, and an auxiliary cylindrical body 7 for stabilizing the socket plate 3 is built-in.

A Swan type socket 8 is fixed in the mounting hole at the center of the socket plate 3, and this socket 8 is connected to the unit cells 4a, 4b by lead wires 6b, 6c.

A swan-type miniature light bulb 9 is attached to this swan-type socket 8.

As shown in detail in FIGS. 2 and 3, the swan miniature light bulb 9 has a plug portion 10 that fits into the socket 8, and a glass bulb 11 having a smaller diameter than the plug portion 10. A transparent cap 12 having an outer diameter that is press-fitted into the socket 8 is attached to the glass bulb 11 portion.

That is, the plug portion 10 and the transparent cap 12 have approximately the same diameter, and have a straight cylindrical shape as a whole.

The transparent cap 12 is made of plastic, and its base is fixed to the plug portion 10, glass bulb 11, and the joint portion with adhesive, for example.

Alternatively, the transparent cap 12 can be fixed by simply press-fitting it into the plug portion without using an adhesive.

As is well known, the plug part 10 of the swan miniature light bulb 9 has two
pins 10a and 10b are provided, and this pin 1
Align 0a and 10b with the grooves of the socket 8, and insert the plug part 10.
When the miniature light bulb 9 is inserted into the socket 8 and rotated by a predetermined angle, the miniature light bulb 9 is correctly attached to the socket 8 and lights up.

This lighting state is shown in FIG.

To turn off the small light bulb 9, remove it from the socket 8 by performing the operation opposite to the above.

Then, as shown in FIG. 3, the posture of the miniature light bulb 9 is reversed, and the head thereof, that is, the tip of the transparent cap 12 is press-fitted into the socket 8.

The miniature light bulb 9 is now stably held in the socket 8, and will not come off even with some vibration or impact.

As explained in detail above, the marker light according to this invention is
To solve the inconvenience of disposing of the light bulb when it is turned off when using a Swan type miniature light bulb, and to make it possible to hold the miniature light bulb in the socket even when the light is turned off, thereby dramatically improving usability.

In addition to this effect, since the glass bulb part of the miniature light bulb is covered with the transparent cap and protected, there is also the effect that it is less likely to be damaged.
