Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ignition device for a signal tube. More specifically, the present invention relates to an ignition device that makes it possible to easily and reliably ignite a signal tube with a simple operation.

In the event of an accident or breakdown of a vehicle on Road 1-1, the vehicle is usually equipped with an emergency fire restraint or flashlight for the purpose of notifying the +1 (driving) of the vehicle's stopping position. People are required to carry smoke canisters and other Shinsou canisters with them.Furthermore, these smoke cannons and other Shinsou canisters are often carried around to ensure the safety of wanderers who are disposing of the incidents that occur. Therefore, since signal tubes are often used in an emergency manner, it is desirable that any number of people can use them reliably and quickly. It is desirable that it can be ignited reliably and safely with simple movements even in the dark, but that it is safe when stored or carried so that it does not emit flames or smoke. There is.

Such a cylinder 1:1' basically consists of a cylinder with an open end filled with a drug such as an inflammatory drug or a smoke-generating drug (signal cylinder main body), and the filled drug exposed at the opening is It is used by lighting it. Normally, signal tubes are stored,
In order to prevent performance deterioration due to flaming or smoke emitting when carried, etc., a fitting cylindrical lid (cap) is placed over the opening to prevent moisture from entering and the filling agent from deteriorating and breaking. .

These signal tubes are suitable for emergency use and require reliable ignition through medium-sized movements.
Transferring powder and pyrotechnic powder (matsutchi) are placed on top of the filled chemical in the first opening (in contact with the filled chemical), and on the other hand, a sliding chemical is placed on the outer surface of the lid body, and when in use, a signal tube is attached. By pulling the main body and lid to fill 'L', then attaching the ignition powder and the sliding powder to ignite the ignition powder, first the transfer powder ignites, and then the filled powder is ignited, causing a flame or smoke. It is configured to do so.

Therefore, when the conventional signal tube as described in -1- is used, the signal tube main body and the lid are separated, and the ignition occurs when the ignition charge in the main body rubs against the sliding charge on the lid. It requires two actions.

Considering the urgency of using a signal tube, it is natural that it is desirable to be able to ignite it reliably and safely with a simpler operation, and for this purpose, various improvements have been made to the ignition device of the signal tube. being done.

For example, Publications No. 38-28700 and No. 39
As described in Publication No. -9447, pyrotechnics were installed on the top of the signal cylinder body filled with a drug such as an inflammatory agent, and on the sides of the -1 and Z sections, while the cylinder that was complimentary to the main body A cylinder is provided with the upper end fixed to the inner surface of the cylinder, and a sliding agent is provided on the inner surface of the lower part of the cylinder, so that a signal can be generated by the action of pulling out the lid from the signal cylinder main body, that is, by the - movement. A device has been devised that can ignite the tube. However, in these ignition devices, reliable contact between the ignition charge and the sliding charge is not guaranteed, so even if the 77 body is pulled out of the designated signal tube body, ignition will definitely occur. However, it could not be said that the reliability was sufficient.

On the other hand, as described in Japanese Utility Model Publication No. 39-34385, pyrotechnics were installed on the top and side surfaces of the signal tube body filled with a chemical such as an inflammatory agent, and on the other hand,
A cylindrical body is provided with the upper end fixed to the inner surface of the cylindrical lid body that compliments the main body, and a sliding agent is installed on the inner surface of the lower part of this cylindrical body.
And by providing a sliding medicine stopper made of an elastic material on the outer periphery of the sliding medicine, the action of pulling out the lid body from the signal cylinder main body,
That is, devices have been devised that can ignite a signal tube with a single action.

However, by making the ignition device of the signal tube have the above-described structure, the structure of the signal tube, especially the cylindrical lid that fits into the main body, becomes complicated. This means that the manufacturing process of the signal tube becomes complicated, leading to high manufacturing costs. Further, since the ignition device of the signal tube has such a complicated structure, the ignition device is easily damaged or deformed during storage or transportation, and it may not be able to operate when necessary due to a failure.

The object of the present invention is to provide an ignition system NU which has a significantly simpler structure compared to prior art ignition systems such as the "2-part" ignition system, and which can achieve reliable and safe ignition. This is the purpose.

The purpose of item 1-1 is as follows: (1) If the signal tube body is in contact with the flaming agent or smoke generating agent filled inside the signal tube body, and a part of it is on the periphery near the top opening of the signal tube body. (2) A cylindrical lid provided in a fitting relationship at the top of the signal tube body, with a ☆jh It consists of a tapered cylindrical lid whose diameter is larger than the diameter of the lower end, and (3) a suriboshi, which is stabbed in a strip along the circumference on the inner surface of the lower part of the cylindrical lid. This can be achieved by the signal tube ignition device 15 of the present invention.

Next, the present invention will be explained in detail.

The present invention provides an ignition device for Shin@kabura, in which a rubbing agent is provided on the lower inner side surface of a cylindrical body that fits into the signal tube body, and the shape of the cylindrical lid body is such that the diameter of the upper end is the same as the diameter of the lower end. By tapering concentrically toward the lower end so as to be larger than the diameter of the lid, the structure of the lid can be simplified and the ignition reliability can be improved.

In other words, by placing the rubbing agent directly inside the lower part of the lid, the need for a cylindrical body, which was conventionally installed with its upper end fixed inside the lid in order to kill the rubbing agent, can be omitted. can do. Furthermore, by making the shape of the lid body as described above, it is possible to omit the elastic body that is conventionally provided on the outside side of the cylinder body where the sliding powder is stabbed to ensure ignition. be.

The lid, which conventionally had a cylindrical shape with the same diameter, has been made concentrically tapered toward the lower end, so that when the lid is pulled out from the signal tube body and ignited, And, it is possible to increase the contact history between the ignition charge provided on the side surface of the two parts and the sliding charge at the bottom of the lid body, thereby making ignition even more reliable. In addition, when storing or carrying, a space is created between the upper side of the signal body and the lid to prevent damage and I-mo drop caused by contact with the lid of the pyrotechnic charge attached to the upper side of the main body. This is something that can be prevented.

Furthermore, the present invention provides a cover between the signal tube body and the cylindrical lid to protect the igniter, thereby preventing accidental ignition due to falling of the igniter, thereby increasing safety. You can also do that. Furthermore, by arranging a circular protection plate with a diameter larger than 1 diameter at the bottom of the lid body between this protective R11i cover and the signal tube body, the ignition powder that has been pierced at the top of the body can be removed by external impact. At the same time, the protective cover can be configured to help the cover be pulled out of the signal tube body together with the cover during ignition.In other words, the cover may be removed from the signal tube body for ignition. When the protective plate is pulled out, its diameter is larger than the diameter of the lower end of the lid, so it gets caught in the middle of the attachment, and the protective plate and protective cover are pulled out together with the lid.This also causes ignition. The certainty of

In order to further enhance the safety of the signal tube, a configuration may be adopted in which the lower portion of the protective cover described in - is squeezed by an elastic body (for example, a rubber band) and brought into close contact with the signal tube main body. Even with such a configuration, the protective cover and the elastic body can be easily and reliably pulled out together with the lid by shaping the lid and the protective plate as shown in the figure.

The ignition device for a signal tube according to the present invention will be explained below with reference to accompanying drawings.

FIG. 1 is a cross-sectional view showing one embodiment of the ignition device of the present invention, and FIG. 2 is a plan view of the signal barrel main body shown in FIG. 1.

In FIG. 1, the inside of a signal barrel body 1 is filled with a combustible agent 2 such as a flame-producing agent or a smoke-generating agent. The signal cylinder main body 1 has the form of a container made of cardboard, plastic material, metal, or the like. The pyrotechnic charge 3 is in contact with the transfer charge 4 filled in a part of the inside of the signal cylinder main body 1 on the top and upper side of the signal cylinder main body 1, and a part of it is on the top of the signal cylinder main body 1. It is attached to the peripheral edge near the opening so as to slightly protrude from the side surface of the main body 1. The transfer powder 4 is in contact with the flame-generating powder or the smoke-generating powder 2 in a form invading a part of the interior of the main body 1 from the top opening. By adopting such a configuration, it is possible to further ensure that the ignition agent ignites the igniter and causes the agent to ignite or smoke.

Regarding the attachment of the ignition charge, it is practical to have the ignition charge 22 extend radially around the top opening 23 of the signal tube body 21 and reach the side surface, as shown in FIG. 2, for example. preferable. In this case, the pyrotechnic charge is attached to the upper side of the main body in a discontinuous band shape along its circumference. When installing the ignition charge as shown in Fig. 2, place a disk 24 made of plastic material or the like in which the part where the ignition charge is to be installed is formed into a radial groove on the top of the signal cylinder main body 21, and then A mode in which the pyrotechnic charge 22 is attached to the radial grooves is practically advantageous. Such a structure effectively prevents the pyrotechnic charge 22 from falling off.

The signal tube body 1 shown in FIG. 1 is fitted with a cylindrical lid (cap) 5 made of the same material as the signal tube body in a complementary manner. This cylindrical lid body 5 has an upper end (i.e., a top portion)
The [=1 diameter is larger than the diameter at the lower end (i.e., near the part where the slider is attached), and its 0 diameter becomes smaller concentrically toward the lower end, so that the diameter at the lower end is equal to the diameter of the main body. It has a tapered shape that slightly exceeds the A rubbing agent 6 is attached to the inner side surface of the lower part of the cylindrical lid body 5 in a band shape along its circumference. The rubbing powder 6 is provided near the lower end of the lid 5, which has a small diameter, in order to strengthen contact with the pyrotechnic powder 3 and ensure its ignition. Also, j
The f5 medicine 6 is provided in a band shape along the circumference of the lid body,
It does not necessarily have to be a continuous band shape, but may be a discontinuous band shape.

The cylindrical lid 5 is designed to prevent moisture from entering the medicine inside the signal cylinder body and to prevent the cylindrical lid from falling off.
It is sealed with the side surface of the signal cylinder main body 1 by a paper 7.

A protective cover 8 for protecting the igniter is provided between the signal tube body 1 and the cylindrical lid 5, and a rib made of a rubber band or the like is attached along the circumference on the lower side of the protective cover 8. A body 9 is provided. The lower end of the protective cover 8 is connected to the lower end of the pyrotechnic charge 3 attached to the side surface of the main body and the slider 41 provided on the side surface of the lid body (1 charge 6
Is it midway between the top and the bottom? 'j8 is in close contact with the side surface of the signal cylinder main body 1 by an elastic body 9. This protective cover 8 is made of a flexible sheet-like material such as Hatron paper or polyethylene sheet. In addition, from the point of view of protecting the ignition powder and improving safety, the lower part of the ignition powder should be made of an elastic body ( It is desirable to have it in close contact with the main body by attaching a rubber band, etc.

However, it is not always necessary to provide an elastic body; for example, the protective cover itself may have a narrowed hem portion.

A circular protection plate 10 made of cardboard, plastic sheet, etc. is arranged between the top of the signal tube body 1 and the protection cover 8. The diameter of this protection plate is larger than the diameter of the lower end of the lid.

Preferably, the diameter of the protection plate is as close as possible to the diameter of the lower end of the lid.

The ignition of the signal barrel having the structure described above is carried out as follows.

If the sealing paper 7 is provided, turn the cylindrical lid 5 against the signal tube body 1 to tear the sealing paper, and if there is no envelope paper, simply place the signal tube body 1 on one side. Support it with your hands and quickly pull out the cylindrical lid 5. Due to this operation, the ignition charge 3 is rapidly rubbed against the sliding charge 6, causing ignition. During this operation, the protection plate 10 has a diameter larger than the r+diameter of the lower end of the cylindrical lid 5, so it is caught on the middle part of the lid 5 and fixed, and is removed from the main body 1 together with the lid 5. It gets pulled out. At this time, the protective cover 8 and the elastic body 9 are also pulled out together because the protective cover is fixed between the lid body 5 and the protective plate 10. Therefore, there will be no occurrence of a situation in which these objects become an obstruction when a fire is ignited.

The ignited igniter 3 rapidly burns, and the agent (flaming agent or smoke agent) that comes into contact with it is quickly, reliably, and safely ignited.

As described above, the present invention is capable of reliably igniting the signal tube in one movement or in small to medium movements. Furthermore, since the structure of the ignition device is very simple, it is less likely to be damaged during transportation or malfunction during use, and it is possible to reduce manufacturing costs by 1ζ.
