(Form for life raft production)
The form for producing a life preserver is a form used for producing a life preserver using an automobile. As shown in FIG. 1, the life-sail making mold 1 includes a bottom plate portion 10 and a surrounding plate portion 20.

  The bottom plate portion 10 has a shape corresponding to the lower shape of the vehicle body of the automobile. Specifically, since an automobile has four tires, the bottom plate portion 10 has a shape that avoids the four tires. For example, a part that interferes with four tires of an automobile from a rectangle or a rectangle with corners dropped. It has a concave shape.

  The surrounding plate portion 20 is a closed-loop surrounding plate erected from the periphery of the bottom plate portion 10. The height of the surrounding plate portion 20 is set to be lower than the height from the ground to the bottom of the vehicle body so that the life raft manufacturing form 1 can be disposed in the lower space of the vehicle body.

  The life preserver mold 1 is manufactured from various materials such as metal, wood, resin, glass fiber reinforced plastic, and carbon fiber reinforced plastic. The life-sail manufacturing mold 1 can be obtained by, for example, casting the base plate 10 into a shape described above from a casting method using a mold having a predetermined shape or a plate-like material, and forming the surrounding plate 20 so as to surround the bottom plate 10. It can be manufactured by a known technique such as being installed and bonded.

(How to make a life raft)
Next, a method for manufacturing a life preserver using the above-described life preserver manufacturing form 1 will be described. First, removable parts such as the engine of the vehicle body CA are removed. This is to increase the amount of foamed resin filled in the vehicle body CA and to reduce the weight of the life preserver so that the obtained life preserver can easily float on water.

  Then, as shown in FIG. 2, the life raft manufacturing form 1 is disposed in a lower space of the vehicle body CA. The life preserver mold 1 is arranged so that the opening faces the bottom of the vehicle body CA. The life-span manufacturing mold 1 may be disposed in the lower space of the vehicle body CA, for example, by lifting the vehicle body CA with a crane or the like and placing the life-sail manufacturing mold 1 under the vehicle body CA.

  Then, the life raft manufacturing form 1 is fixed to the vehicle body CA. The fixing method of the life raft manufacturing form 1 may be performed by a known method. For example, as shown in FIG. 2, there is a method of pressing and fixing the life raft manufacturing form 1 to the vehicle body CA with a jack 30. In addition, there is a method of lifting the life raft manufacturing form 1 with a rope or a chain and fixing it to the vehicle body CA.

  After fixing the life raft manufacturing form 1 to the lower part of the vehicle body CA, the foamed resin material is filled from the opening of the vehicle body. For example, the hood (engine hood) is opened and the engine room is filled with the foamed resin material. Also, the trunk hood is opened and the trunk room is filled with foamed resin material. In addition, since a plurality of holes are usually formed on the cabin floor when the interior is peeled off, the foamed resin material can be filled from the holes. Since the foamed resin material has fluidity, it flows downward, but it is received by the lifeboat manufacturing form 1 installed and fills the space of the vehicle body CA.

  The foamed resin to be used is not particularly limited, and various types such as foamed polyurethane, foamed polystyrene, foamed polyethylene, foamed polypropylene, foamed polyphenol, and foamed rubber can be used. In addition, these materials may be used independently and may use 2 or more types together.

  The filled foamed resin material is foamed and cured over time, and becomes a foamed resin molded body PF corresponding to the shape of the filled portion as shown in FIG. In this way, the space of the vehicle body CA, specifically, the space surrounded by the engine room, the trunk room, and the like excluding the cabin of the vehicle body and the life-saving mortar mold 1 can be filled with the foamed resin molded body PF. Since the vehicle body CA and the life-seal manufacturing mold 1 are bonded together by the foamed resin molded body PF, a life-sail integrated with the vehicle body, the life-sail manufacturing mold 1 and the foamed resin molded body PF is obtained.

  Thus, by using the life-sail manufacturing form 1, it is possible to easily manufacture a life-skill by using a vehicle body such as a scrap car. Furthermore, the working time can be shortened and the manufacturing cost can be reduced.

  The life preserver obtained as described above floats in the water due to the buoyancy of the foamed resin molded body PF in the event of a disaster such as a tsunami or a typhoon. For this reason, those who are late or who are unable to evacuate quickly can board and evacuate. In addition, since the vehicle body CA is a closed space, a person who has evacuated to a life raft can be prevented from being injured because the vehicle body CA can protect the collision of drifting objects.

  Moreover, since the exposure of the foamed resin molded product PF is suppressed by the life-seal manufacturing mold 1, the foamed resin molded product PF is suppressed from being deteriorated by ultraviolet rays or the like, and is excellent in weather resistance.

  Since the engine room and the trunk room of the vehicle body CA have irregularities, the foamed resin molded body PF molded so as to fill the irregularities is less likely to come off from the vehicle body CA. In order to further suppress the release from the CA, the engine room may be filled with a foamed resin material after grafting with a rod-like body or the like. Since the foamed resin molded body PF is molded so as to cover the graft, it is possible to suppress the foamed resin molded body PF from coming off the vehicle body CA.

  In addition, when the battery is removed, the window glass cannot be opened or closed with the electric window glass. In this case, it is possible to manually open and close the window glass by attaching a handle to the window glass and pinching the handle to move up and down. This is useful when the door of the vehicle body CA cannot be opened due to damage or the like when the vehicle is ventilated or a safe place is reached.

  In addition, although the single life-sail manufacturing form 1 was demonstrated above, the baseplate part 10 may be comprised from the some division | segmentation form.

  For example, it may be configured by a right split mold 2a and a left split mold 2b like a life preserver mold 2 shown in FIG. Each of the bottom plate portions 10 of the right divided mold frame 2 a and the left divided mold frame 2 b is provided with a surrounding plate portion 20 standing along the periphery of each bottom plate portion 10, and surrounds each bottom plate portion 10. Then, by attaching the right split mold 2a and the left split mold 2b, as described above, the bottom plate 10 has a shape corresponding to the shape of the bottom of the vehicle body CA.

  For example, when the life raft manufacturing form 2 is disposed below the vehicle body CA, it can be performed as follows. As shown in FIG. 5, without lifting the vehicle body CA, the right-side divided mold frame 2a and the left-side divided mold frame 2b are overlapped and inserted so as to pass between the left and right tires of the vehicle body CA from the front or rear of the vehicle body CA. . If the sum of the heights of the right split mold 2a and the left split mold 2b is set to be smaller than the height from the ground to the bottom of the vehicle body CA, the vehicle body can be overlapped even if the right split mold 2a and the left split mold 2b are overlapped. It can be inserted without interfering with CA.

  Then, as shown in FIG. 6, the right split mold 2a is moved to the right side of the vehicle body CA, and the left split mold 2b is moved to the left side of the vehicle body CA. Thus, in the life-sail manufacturing mold 2, the right split mold 2 a and the left split mold 2 b can be arranged below the car body without floating the car body CA.

  Moreover, you may be comprised from the front side division | segmentation mold frame 3a, the center division | segmentation mold frame 3b, and the rear side division | segmentation mold frame 3c like the form 3 for lifeboat manufacturing shown in FIG. Here, the bottom plate portion 10 of the central divided mold 3b is substantially rectangular, and the bottom plates 10 of the front divided mold 3a and the rear divided mold 3c are substantially T-shaped. A surrounding plate portion 20 is erected along the periphery of each bottom plate portion 10 to surround the bottom plate portion 10.

  In the case where the above-mentioned life raft manufacturing form 3 is disposed in the lower space of the vehicle body CA, as shown in FIG. 8, the front division mold 3a is from the front of the vehicle body CA, and the center division mold 3b is the side of the vehicle body CA. From the rear of the vehicle body CA, the rear divided mold 3c can be inserted and arranged in the lower space of the vehicle body CA. Thus, in the life raft manufacturing mold 3, the front divided mold 3a, the center Since the divided mold frame 3b and the rear divided mold frame 3c can be inserted into the lower space of the vehicle body CA from different directions, they can be easily arranged without contacting each other and interfering. it can.

  In the above description, the life raft manufacturing molds 2 and 3 in which the bottom plate portion 10 is divided into two or three have been described, but may be divided into four or more.
