  In the first and second embodiments, the center of the bottom of the injection table is connected and fixed to one end of the third piston rod. However, the present invention is not limited to this. For example, as shown in FIG. 10A, the injection device may be configured such that one end 544 of the third piston rod 543 penetrates the injection table 505 and directly contacts the parachute or paraglider 510. In this case, the displacement of the parachute or paraglider 510 on the injection table 505 can be suppressed, and directivity can be provided in the injection direction. Therefore, since the emission direction can be controlled more than in the first embodiment and the second embodiment, as shown in FIG. 10B, the parachute or paraglider 510 can be emitted to the outside stably. In FIGS. 10A and 10B, portions where the lower two digits of the reference numerals are the same as the lower two digits of the reference numerals of the first embodiment are the same as the portions shown in the first embodiment unless otherwise specified. Since this is a part, the description is omitted.

  The shape of the dome-shaped member in the first and second embodiments before separation is not particularly limited, but is preferably a circle, an ellipse, or a rectangle in plan view. Further, as shown in FIGS. 11A and 11B, when the shape of the dome-shaped members 603 and 703 before separation is an ellipse or a rectangle in plan view, the dome-shaped members 603 and 703 have a flat shape. More preferably, it is formed so as to be separated along the long axis. For example, in FIG. 11A, the dome-shaped member 603 has dome-formed members 603a and 603b separated along the major axis of the ellipse. Each of the dome forming members 603a and 603b is separated from the state where the contact surfaces 601a and 601b are in contact with each other, thereby forming an opening in the container. In the injection device using the dome-shaped member 603, the opening distance (distance in the short-axis direction) in the container is shorter than when a circular dome-shaped member is used in plan view. Can be shortened compared to the first and second embodiments, and the dead space can be reduced. The same applies to the dome-shaped member 703 shown in FIG. In FIGS. 11A and 11B, portions where the lower two digits of the reference numerals are the same as the lower two digits of the reference numerals of the first embodiment are the same as the portions shown in the first embodiment unless otherwise specified. Since this is a part, the description is omitted.

  In the first and second embodiments, a container having a shape in which a truncated cone is turned upside down may be used as the container. Hereinafter, an injection device according to a modification of the first embodiment will be described with reference to FIG. In FIG. 12, the parts whose lower two digits are the same as those of the first embodiment are the same as the parts shown in the first embodiment unless otherwise specified. Omitted.

  As shown in FIG. 12, in the injection device 800, the container 801 has a cylindrical member 802 having a hole near the center in the upper part, and a cylindrical member 802 so that the hole communicates with the inside of the cylindrical member 802. A dome-shaped member 803 provided so as to cover an upper part of the hole of the member 802. The cylindrical member 802 is formed in a cylindrical shape whose diameter gradually decreases from the upper part to the lower part. Further, the cylindrical member 802 has semi-cylindrical members 802a and 802b separated at the center. The semi-cylindrical member 802a is connected at an upper end to the dome forming member 803a, and at a lower end to one end 824 of the first piston portion 821. Similarly, the semi-cylindrical member 802b is connected at an upper end to the dome forming member 803b, and at a lower end to one end 834 of the second piston portion 831. With the injection device 800 having such a configuration, the same operation and effect as those of the first embodiment can be obtained, and further, the size and weight of the injection device 800 can be reduced.

  In the third embodiment, the plate member is an elastic member made of rubber or the like. However, the present invention is not limited to this. For example, the plate member may be made of a shape memory alloy having shape memory characteristics. Is also good. In the third embodiment, the case where the upper portion of the cylinder portion is open is described. However, the present invention is not limited to this. For example, the opening portion of the cylinder portion is closed by a lid in an initial state. The lid may be detached from the opening by pushing a parachute or a paraglider.

  After solidifying on the back surface of the plate member 390 forming the container 301 of the third embodiment (on the side of the container 301 in the state where the container 301 is formed), the plate member 390 is removed. A paint having a lower coefficient of friction than the back surface may be applied. As a result, the sliding resistance between the side of the container 301 and the locking portions 391a and 391b after the locking of the locking portions 391a and 391b is released is reduced, so that the container 301 is smoothly deployed, The plate member 390 can be quickly returned to the original plate shape. That is, it is possible to suppress a decrease in the injection speed from before the application of the paint.

  In each of the above embodiments, it is preferable that the injection table is partially hollowed out as necessary, for example, by providing a hole penetrating from the upper side to the lower side, or by forming a mesh. Thus, the weight of the injection table can be reduced, and thus the weight of the entire injection device can be reduced.

  The gas generator used in each of the above embodiments may be either a non-explosive type or an explosive type. The non-explosive type mainstream is to connect a sharp member such as a needle and a compressed spring to a gas cylinder filled with gas such as carbon dioxide or nitrogen, and to use the spring force to fly the sharp member and seal the cylinder. The gas is released by colliding with a sealing plate. At this time, a drive source such as a servomotor is usually used to release the compression force of the spring. In the case of the explosive type, an igniter may be used alone, or an igniter and a gas generating agent may be provided.

  In addition, the gas generator used in each of the above embodiments uses a hybrid type, stored type gas generator that ruptures a sealing plate in a small gas cylinder with the force of explosives and discharges internal gas to the outside. Is also good. In this case, the pressurized gas in the gas cylinder is selected from at least one of nonflammable gases such as argon, helium, nitrogen, and carbon dioxide.

  Further, the gas generator used in each of the above embodiments may include an explosive-type heating element in order to reliably inflate when the pressurized gas is released.

  Further, the gas generator used in each of the above-described embodiments may include, as necessary, a filter used for removing residue and cooling of generated gas, and / or an orifice for adjusting a gas flow rate. good.
