(First embodiment)
FIG. 1 is a side view showing a configuration of a firearm 2 in which the recovery device according to the first embodiment is used. The recovery device is used in various firearms 2 including automatic firearms such as machine guns and machine guns. The firearm 2 is installed via a gun rack 5 on an installation surface 4 of an installation object such as the ground, a vehicle, and an aircraft. The firearm 2 is supported by the gun rack 5 so as to be able to rotate up and down around the horizontal axis 5a and to turn around the vertical axis.

  At the time of shooting, the residue is discharged from the discharge port 3 provided in the firearm 2. The position and number of outlets 3 and the type of residue depend on the type of firearm 2. Examples of residues are medications and links. A medicine case is a cylindrical case that stores a propellant in a real package. A link means what connects a some real package and comprises a bullet band. The residue is discharged from the discharge port 3 at a moment according to the discharge mechanism of the firearm 2. Here, for convenience of explanation, the discharge port 3 is illustrated as being exposed to the outside.

  FIG. 2 is a side sectional view showing the configuration of the recovery apparatus 1 according to the first embodiment, and FIG. 3 is an external perspective view thereof. In FIG. 3, the gun rack 5 and an urging device 21 described later are omitted.

  The collection device 1 includes a storage unit 11, a transport unit 16, and an urging device 21. The accommodating part 11 accommodates and collects the residue 6. The accommodating portion 11 is provided separately from the firearm 2. That is, the accommodating part 11 is provided away from the firearm 2, and relative movement of the firearm 2 with respect to the accommodating part 11 is allowed. The container 11 is a hard box-like container in this embodiment, but may be a container such as a soft bag. In addition to this, the accommodating portion 11 may be configured by a closed space provided inside a structure that is an installation target such as a vehicle or an aircraft. The shape and dimensions of the container 11 are set according to the size and the amount of the residue 6 to be collected.

  The transport unit 16 connects the discharge port 3 of the firearm 2 and the introduction port 12 provided in the storage unit 11. The inlet 12 is disposed at a lower position than the outlet 3. The transport unit 16 includes a passage member 17 that guides the residue 6 from the discharge port 3 to the storage unit 11 by dropping the residue 6 by its own weight. The passage member 17 is composed of a flexible tube 18 made of a material that can be bent and stretched. The conveyance unit 16 moves following the movement of the firearm 2 as the passage member 17 bends and expands and contracts.

  The flexible tube 18 is connected to the introduction port 12 of the housing portion 11, and is connected to the discharge port 3 via the guide tube 19. The guide tube 19 is made of a hard material such as metal. The residue 6 discharged from the discharge port 3 is guided into the passage member 17 while colliding with the inner wall surface of the guide tube 19. The flexible tube 18 may be directly connected to the discharge port 3. These members are detachably connected using known connection means such as screws and pins.

  In FIG. 3, a plurality of discharge ports (not shown) of the firearm 2 and the housing part 11 are connected by a plurality of transport parts 16. Each of the plurality of outlets discharges the medicine and the link. Hereinafter, for the sake of simplicity of explanation, it is assumed that the firearm 2 and the storage unit 11 are connected by a single transport unit 16.

  Returning to FIG. 2, the urging device 21 includes a fixing member 23 and an elastic member 25. The fixing member 23 includes a hose clamp or the like, and a plurality of fixing members 23 are fixed in the longitudinal direction of the passage member 17. The elastic member 25 is composed of a tension spring, but may be composed of linear rubber or the like. The elastic member 25 is provided with hooks (not shown) at both ends thereof, and is fixed by hooking hooks into through holes formed in the fixing member 23. Both ends of the elastic member 25 are fixed in a state where the elastic member 25 extends in the longitudinal direction of the passage member 17. Tension is applied to the passage member 17 by the elastic restoring force of the elastic member 25, and the passage member 17 is biased in a direction in which the passage member 17 contracts.

  It is preferable that the biasing device 21 always biases the passage member 17 within a movable range in which the firearm 2 supported by the gun rack 5 moves. In the present embodiment, tension is applied to the passage member 17 by the elastic member 25 when the discharge port 3 is closest to the introduction port 12 of the housing portion 11. Even when the discharge port 3 is separated from this position, the passage member 17 is always urged by the elastic member 25 extending. Thereby, even if the passage member 17 moves following the movement of the firearm 2, the passage member 17 is stably urged.

  A plurality of elastic members 25 are attached around the central axis P1 of the passage member 17 at equal angular intervals. In the illustrated example, two elastic members 25 are attached around the central axis P1 of the passage member 17 at an interval of about 180 °. When the four elastic members 25 are attached, they are attached around the central axis P1 of the passage member 17 at an interval of approximately 90 °. By attaching the elastic members 25 at equiangular intervals, the urging force is evenly applied in the circumferential direction of the passage member 17, and the deflection of the passage member 17 in the range S1 in which the elastic members 25 are attached is suppressed.

  The elastic member 25 is attached to a portion of the passage member 17 near the accommodating portion 11. Thereby, even if the passage member 17 moves following the movement of the firearm 2, the elastic member 25 is hardly moved, and the passage member 17 is stably biased.

  FIG. 4 is a side view showing a state of the recovery device 1 when the firearm 2 moves. In FIG. 4, a state when the outlet 3 is moved away from the accommodating portion 11 is indicated by a solid line, and a state when the outlet 3 is moved closer is indicated by a two-dot chain line. When the discharge port 3 is separated from the storage portion 11, the passage member 17 extends following the movement of the firearm 2, and the length from the discharge port 3 to the storage portion 11 is increased. On the other hand, when the discharge port 3 approaches the accommodating portion 11, the passage member 17 is contracted by the urging force of the urging device 21, and the deflection thereof is suppressed. As described above, the urging device 21 is provided as a deflection suppressing unit that suppresses the deflection of the passage member 17.

  The effect of the collection device 1 according to this embodiment will be described. Fig.5 (a) is side sectional drawing which shows the structure of the collection | recovery apparatus 1 in which the urging | biasing apparatus 21 is not provided, FIG.5 (b) is an enlarged view of the B section of Fig.5 (a).

  If the urging device 21 is not provided, the passage member 17 bends when the firearm 2 moves so that the discharge port 3 approaches the accommodating portion 11. Residue 6 is likely to stay at a location where the passage member 17 is bent. If the residue 6 stays, the residue 6 may be clogged in the passage member 17, and it is necessary to stop shooting to remove the clogging. The stagnation of the residue 6 is more likely to occur as the firing rate of the firearm 2 is higher.

  On the other hand, according to the collection device 1 according to the present embodiment, since the deflection of the passage member 17 is suppressed by the urging device 21, even if a large amount of residue 6 is discharged from the firearm 2 with a high firing rate, removal of clogging is performed. Therefore, the residue 6 can be collected without stopping the shooting. Further, it is not necessary to integrally attach the accommodating portion 11 of the recovery device 1 to the firearm 2, and the weight of the entire firearm 2 is not increased by the residue 6 after the recovery, so that the residue 6 is maintained while maintaining the operability of the firearm 2. The amount recovered can be greatly increased. Further, since the passage member 17 moves following the movement of the firearm 2, the residue 6 can be recovered while maintaining the operability of the firearm 2. Further, since the residue 6 is guided by dropping in the passage member 17 by its own weight, a complicated mechanism for collecting the residue 6 is not required and can be easily realized.

(Second Embodiment)
FIG. 6 is a partial perspective view showing the configuration of the urging device 21 according to the second embodiment. In the following embodiments, the same elements as those described in the first embodiment are denoted by the same reference numerals, and redundant descriptions are omitted.

  When the passage member 17 is contracted and bent by the urging device 21, the passage member 17 may come out from between the plurality of elastic members 25. In order to prevent the passage member 17 from coming off, the elastic member 25 according to this embodiment is attached in a spiral shape along the longitudinal direction of the passage member 17. Thereby, the elastic member 25 contacts a wide range in the circumferential direction of the passage member 17, and the elastic member 25 can prevent the passage member 17 from coming out.

  In each elastic member 25, the inclination of the elastic member 25 with respect to the longitudinal axis of the passage member 17, the number of the elastic members 25, and the like are adjusted so that the passage member 17 is prevented from coming out. In the illustrated example, the other elastic member 25 adjacent in the circumferential direction is adjusted to be disposed at a position spaced from the one elastic member 25 in the longitudinal direction of the passage member 17. For example, the point C2 of the other elastic member 25B is arranged at an interval in the longitudinal direction of the passage member 17 from the point C1 of one elastic member 25A.

(Third embodiment)
FIG. 7 is a side cross-sectional view showing the configuration of the collection apparatus 1 according to the third embodiment. As for the channel | path member 17 which concerns on 3rd Embodiment, the edge part 17a is inserted in the accommodating part 11 so that advancing and retreating is possible. The conveyance unit 16 moves following the movement of the firearm 2 as the passage member 17 moves forward and backward to the housing unit 11 and the passage member 17 is bent. One end portion 25 a of the elastic member 25 of the urging device 21 is fixed to the fixing member 23, and the other end portion 25 b is fixed to the accommodating portion 11. The passage member 17 is urged by the elastic member 25 in the direction of entering the accommodating portion 11.

  FIG. 8 is a side sectional view showing a state of the passage member 17 when the firearm 2 (not shown) moves. In FIG. 8, the state when the discharge port 3 (not shown) moves away from the accommodating portion 11 is indicated by a solid line, and the state when the discharge port 3 moves so as to approach is indicated by a two-dot chain line. When the discharge port 3 is separated from the storage portion 11, the passage member 17 is pulled out from the storage portion 11 following the movement of the firearm 2, and the length from the discharge port 3 to the storage portion 11 is increased. On the other hand, when the firearm 2 moves so that the discharge port 3 approaches the accommodating portion 11, the passage member 17 enters the accommodating portion 11 by the urging force of the urging device 21, and the deflection thereof is suppressed.

  According to the third embodiment described above, since the deflection of the passage member 17 is suppressed even if the passage member 17 is not configured to be stretchable in the longitudinal direction, the flexible tube 18 or the like that is not stretchable in the longitudinal direction is provided. It can be used for the passage member 17 and the degree of freedom in design is improved.

  As mentioned above, although this invention was demonstrated based on embodiment, embodiment shows only the principle and application of this invention. In the embodiment, many modifications and arrangements can be made without departing from the spirit of the present invention defined in the claims.

  The recovery device 1 may be used for a firearm 2 that is not supported by the gun rack 5 in addition to the firearm 2 supported by the gun rack 5. Moreover, the conveyance part 16 may be comprised combining a some metal member, and a hopper etc. may be arrange | positioned in the middle. Further, the deflection of the passage member 17 may be suppressed by means other than the urging force by the urging device 21.
