Description

[Detailed Description of the Invention] [Field of the Invention] The present invention relates to a vertical shooter, and more particularly to a vertical shooter that is installed on a ship and can be efficiently lowered from the ship to the sea surface in the event of a ship accident that requires abandoning the ship. It is related to.

[Background of the invention]

As shown in Fig. 1, such a vertical shooter consists of a vertically extending shooter body 1 of arbitrary shape and a platform 2 installed at the bottom of the shooter body 1 and floating on the edge of the sea surface. A ramp 3 is formed between platform 1 and platform 2, allowing evacuees who have descended vertically to safely descend onto platform 2.

A storage case 4 is provided on the upper part of the main body 1 of the partial shutter, and by opening this storage case 4, the storage case 4 can be folded up from the deck of the ship S on which the storage case 4 is installed. A vertical shooter can be dropped onto the sea surface. At this time, the boat main body 1 extends perpendicularly to the side of the ship S, and gas is automatically injected into the air chamber 5 of the platform 2 and expands, forming a boat shape and forming the configuration shown in FIG. It is something to take. Further, an awning 6 is provided over the lower end of the shelter body 1, the side end of the platform 2, and the end opposite thereto, so as not to create fear in the evacuees.

Such a vertical sleeve shoe body 1 has a protective body 7 forming an outer wall of the shoe body 1 and a cylindrical slideway body 8 housed coaxially within the protective body 7.

The slideway body 8 is a slideway body main body 8 made of a strong material such as a long canvas, as shown in a developed view in FIG.
0 and a meandering runway cloth 81 provided in a zigzag pattern on the main body 80 of the runway body 80, the meandering runway cloth 81 is
As shown in the figure, it is adhered to the downhill main body 80 by sewing or the like so as to form a downhill path 83. Further, the lateral end portions 82 of the main body 80 of the main body 80 are bonded together to form a columnar main body 8 (see FIG. 4).

As the evacuees slide down the meandering slideway 83 composed of the meandering slideway fabric 81 and the slideway main body 80, the downhill speed is reduced due to the meandering of the slideway 83, and the evacuees are guided safely to the ramp 3. , it is now possible to reach Plant Form 2.

By the way, when the evacuee 9 slides down the meandering runway 83 mentioned above, the evacuee 9 wears a life jacket or clothes, but such a tangible object is electrically insulating, Since the sliding body main body 80 and the meandering runway cloth 81 are both made of tangible material and are electrically insulating, static electricity will accumulate on the evacuee 9 when sliding down the meandering route 83. . When the static electricity accumulated in the human body comes into contact with a conductor, it is rapidly discharged, causing not only a so-called electric shock but also the generation of minute sparks. There was a risk of secondary disasters if the ship was carrying flammable cargo.

[Summary of the invention]

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a vertical shooter that prevents static electricity from accumulating on evacuees when sliding down a meandering slideway formed in a vertically extending shooter body. The purpose is to

Therefore, in the vertical shooter according to the present invention, a meandering runway cloth is attached to a long runway body having good strength so as to form a meandering runway having a plurality of bends, and further A vertical shooter having a cylindrical runway body bonded to each other, characterized in that at least a part of the part of the runway body forming the runway is made of conductive cloth with a resistance value of 102 to 105 Ω. That is.

According to the vertical shooter of the present invention, at least a part of the slideway portion of the slideway main body and the meandering slideway fabric that constitute the meandering slideway, on which the load of evacuees is not so much applied, is made of conductive fabric. This has the advantage that static electricity does not accumulate during the downhill skiing of 11 people, and secondary disasters due to static electricity discharge can be prevented.

[Detailed description of the invention]

As shown in FIGS. 2 to 4, the vertical shooter according to the present invention has a meandering runway cloth 81 attached to a long runway main body 80 in a jagged manner so as to form a meandering runway (a third The lateral ends 82 of the downhill main body 80 are bonded together to form a cylindrical shape (see FIG. 4).

The conventional downhill main body 80 has conventionally been made of a long cloth such as canvas having high strength, and has not been subjected to any conductive treatment. According to the present invention, as shown in FIG. 5, a conductive cloth 84 is used for at least a portion of the portion of the downhill body 80 that constitutes the downhill path 83.

Such conductive cloth must have a resistance value suitable for corona discharge in order to prevent static electricity from accumulating on the evacuee due to the evacuee's descent. That is, a conductive cloth having a resistance value in the range of 10 2 to 10 5 Ω is used. By using a material with such a conductive range, static electricity from the human body is released to the outside through corona discharge through the conductive cloth.
Static electricity will no longer accumulate in the human body.

Since the conductive cloth 84 and the downhill cloth 81 constitute the downhill body 80 or the meandering downhill path 83, a certain degree of strength is required. Further, the strength must be such that it will not break even if used by a sufficiently heavy evacuee, and in practical terms, it is required to have a sufficient margin for this strength. therefore,
Considering these points, it is preferable that the strength of the meandering downhill cloth 81 and the conductive cloth 84 is 400 g/m (22nd grade) or more. Also, the tensile strength is 50Kg
It is preferable that the tear strength is 17 Kg/cm or more, and the tear strength is 17 Kg/cm or more.

Furthermore, it is necessary that the meandering downhill cloth 81 and the conductive cloth 84 according to the present invention have appropriate stretchability, and the stretchability of the downhill runningway cloth 81 and the conductive cloth 84 in the length direction is 30 to 60%. % in the circumferential direction, and preferably 15 to 30%, and the breaking strength is preferably 140% or more.

Since such a vertical shooter according to the present invention is used only in an emergency such as a marine accident, it is normally stored in a storage case.

Therefore, the conductive cloth 84 and the meandering runway cloth 81 provided on the runway body 80 of the runway body 8 must be weather resistant, and in addition, the conductive cloth 84 and the meandering runway cloth 81 provided on the runway body 80 must be weather resistant. In order to achieve this, it is preferable that the material has good abrasion resistance.

The abrasion resistance of the meandering downhill road fabric 81 and the conductive fabric 84 is preferably 1000 times or more in the JISL 1079 abrasion resistance test. If the number of times is less than 1,000 times, the meandering downhill road cloth 81 and the conductive cloth 84 may become damaged due to electric shock caused by the evacuee 9 sliding down the slope, or they will not exhibit conductivity due to abrasion and the effect of preventing the accumulation of static electricity will be lost. This is because it decreases.

In addition, the conductive cloth 84 needs to be connected to the meandering runway cloth 81 or the runway-resistant main body 80 in order to configure the meandering runway 83, but in order to ensure peel strength in this connection, it is possible to sew it. It is preferable to use cloth. This is because if they are connected using adhesive, there is a risk that the adhesive may deteriorate due to long-term storage.

Furthermore, in consideration of use in a ship where a fire has occurred, it is preferable that the material be flame retardant.

Such a conductive cloth body 84 is not fundamentally limited in the present invention. Preferably, a conductive cloth that satisfies the above conditions is selected. As such a conductive cloth, for example, a conductive cloth in which conductive fibers such as metal fibers and carbon fibers are woven, or a conductive cloth in which a conductive paint is applied to a heavy body can be used.

〔Effect of the invention〕

As explained above, the vertical shooter according to the present invention is
Since conductive cloth was provided on the meandering path that makes up the main body of this vertical shooter, evacuees can move along the meandering path /i! In the case of one descent, there is no risk of static electricity accumulating on the M passenger, and there is an advantage that ignition of flammable gas or the like caused by discharge of static electricity can be prevented.
