Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flameproof device for a vehicle ashtray device, and more particularly to a flameproof device for a vehicle ashtray device that effectively extinguishes fire inside the ashtray when the ashtray is in use.

As a conventional vehicle ashtray device, a drawer-type retractable ashtray device will be explained as an example.
an ashtray 2 for storing the ashtray 2, etc., and a storage case 4 that covers the upper part of the ashtray 2 when it is stored and is attached to the front lower part of the instrument panel 3 and holds the ashtray 2 so as to be freely retractable.
Therefore, when the ashtray 2 is used, the ashtray opening 5 is opened by pulling out a predetermined amount of the ashtray 2 from the storage case 4.

In addition, 6 is a guide protrusion extending in the front-rear direction on both side walls of the ashtray 2, and 7 is a guide rail provided on the inner surface of both side walls of the storage case 4 to slidably hold the guide protrusion 6.
Reference numeral 8 denotes an extinguishing board for rubbing the butts 1 formed in the ashtray 2.

In addition, the ashtray disclosed in Japanese Utility Model Application Publication No. 53-15992 has a similar structure.

However, in such a conventional vehicle ashtray device, when using the ashtray 2, the smoker must completely extinguish the flame in the cigarette butt 1 with the extinguishing board 8, and then place the cigarette butt 1 into the ashtray 2. As a general rule, the fire should be poured into the smoker, but sometimes the fire doesn't go out even though you tried to put it out completely.

Generally, cigarette butts 1 are placed in the ashtray, but sometimes cellophane paper for cigarette packaging may also be placed there.

In such a case, if the fire in cigarette butt 1 is not completely extinguished,
The fire spreads to easily combustible materials such as the cellophane paper that have already been stored, and especially when there is a large amount of combustible material, the inside of the ashtray 2 becomes hotter than expected, which not only adversely affects other built-in parts such as instruments, but also causes the ashtray to open. There is a problem in that the flame 9 rises from the flame 9 and burns the resin instrument panel 3, etc., and may even cause a vehicle fire.

The present invention was developed based on the above points, and its purpose is to place a flameproof plate on the top of the ashtray,
This flameproof plate is activated to close the ashtray opening when a fire ignites inside the ashtray, thereby preventing unexpected accidents such as equipment incineration or vehicle fire due to ignition inside the ashtray. The purpose is to provide a flameproofing device.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the embodiments shown in FIGS. 3 to 6, the ashtray device includes:
This ashtray device has a structure similar to that of the conventional example shown in FIG. A flameproofing device is provided which includes a spring 11 as an actuating member and an adhesive layer 12 for fixing the flameproofing plate 10 to the storage case 4.

In this embodiment, the flameproof plate 10 is a rectangular plate material having a size that covers the ashtray opening 5 when the ashtray 2 is in use, and is disposed on the upper surface of the upper wall on the front side of the storage case 4. The ashtray 2 is held slidably along the direction in which the ashtray 2 is pulled out by single-shaped holders 13 fixed to both side walls of the ashtray 4 by spot welding or the like.

The spring 11 has one end fixed to the rear upper wall of the storage case 4 via a stopper 15, and the other end attached to a cut-and-raised piece 16 provided at the rear end of the flameproof plate 10. The flameproof plate 10 is fixedly attached, and the flameproof plate 10 is always urged in the direction of closing the ashtray opening 5.

Note that 17 is a support guide that holds the spring 11.

Furthermore, as shown in FIG. 4, the adhesive layers 1 and 2 are used to fix the flameproof plate 10 to the storage case 4 at the position where the ashtray opening 5 is opened when the ashtray 2 is used. The material layer 12 is formed using a thermoplastic material such as paraffin.

In the above embodiment, the storage case 4 is attached to the instrument panel 3 via a bracket 14 having a predetermined shape, taking into account the space for arranging the flameproof plate 10 on the upper surface of the upper wall of the storage case 4.
It is attached with screws 18, etc.

Therefore, according to the flameproofing device for a vehicle ashtray device according to this embodiment, since the flameproofing plate 10 is placed on the earthen wall of the storage case 4 by the adhesive layer 12 in the normal state, the flameproofing plate 10 The ashtray opening 5 is not narrowed by the plate 10, and there is no risk that the usability of the ashtray 2 will be impaired.

In addition, if the cigarette butts 1, etc. start burning due to the smoker's negligence while using the ashtray 2, in other words, in an emergency, the inside of the ashtray 2 will become extremely hot, as shown in FIG. Because it will be in a state where flame 9 will rise,
The adhesive layer 12 will be softened or further melted by the heat inside the ashtray 2.

At this time, as the adhesive layer 12 softens or melts,
The adhesive force of the adhesive layer 12 is weakened, and the flameproof plate 10 is
The biasing force of the spring 11 overcomes the adhesive force of the adhesive layer 12, so that the ashtray moves in the direction of closing the ashtray opening 5, collides with the inner surface of the front wall of the ashtray 2, and stops.

As a result, the inside of the ashtray 2 becomes substantially airtight, and the flame 9 inside the ashtray 2 is naturally extinguished due to lack of oxygen.

In addition, in the above embodiment, the flameproof plate 10 is attached to the storage case 4.
Although the spring 11 is disposed on the upper surface of the earthen wall of the storage case 4, it is not necessarily limited thereto, and may be placed on the lower surface of the earthen wall of the storage case 4. In addition, in the above embodiment, the spring 11 is used as the actuating member. However, any type of flame retardant plate 10 may be used as long as it operates.

Furthermore, as for the material of the adhesive layer 12, as long as it is a thermoplastic material, other than the above-mentioned paraffin, polyethylene, polypropylene, vinyl chloride, hot melt sheet, etc. can be used.

In the case of the present invention, it is sufficient to fix the flameproof plate 10 to the storage case 4 against the biasing force of the spring 11, and since the adhesive area can be relatively large, it is possible to use a flameproof plate 10 even if the adhesive force is not so strong. can.

Moreover, it is also possible to use the above-mentioned materials or other materials in combination as appropriate.

Of course, if you choose a material with strong adhesive strength, the spring 1
It becomes possible to set a strong biasing force for the 1st class, so even if there are many cigarette butts in the ashtray 2, the flameproof plate 10
can be operated reliably, and the operating time can be shortened.

As explained above, according to the flameproofing device for a vehicle ashtray device according to the present invention, a flameproofing plate is arranged above the ashtray that is held in a storage case so as to be removable, and this flameproofing plate is attached to the operating member. The flame retardant plate is urged to close the ashtray opening by the adhesive layer, and the flame retardant plate is fixed in a position where the ashtray opening is normally opened by the adhesive layer, and the flame retardant plate is actuated by sensing the ignition state inside the ashtray. Therefore, the ashtray device can quickly and reliably extinguish a fire inside the ashtray without impairing its usability and with an extremely simple structure.

Therefore, unexpected accidents such as equipment incineration or vehicle fire due to ignition inside the ashtray can be prevented.
