And a connecting pin for connecting the auxiliary lamp, and when the auxiliary lamp is stored, the connecting pin is pulled out, and after the movable lug plate is rotated, the auxiliary lamp is tilted with the first follower as a fulcrum. It was.

  According to the first invention, when the auxiliary lamp is stored, the first follower comes into contact with the first rail and the auxiliary lamp comes into contact with the first rail as the auxiliary lamp is tilted around the end hinge. As the first follower is tilted around the fulcrum, the second follower contacts the second rail.

  As a result, the inclination angle of the first and second rails is not determined by the posture of the auxiliary lamp at the coupling position, and the first and second rails are formed to extend substantially horizontally from the coupling position to the lamp door to the storage position. It becomes possible to do. When the first and second rails extend substantially horizontally, a large force is not required when sliding the auxiliary lamp against gravity during storage, and one worker can easily work.

  Further, it is not necessary to use a winch or the like to slide the auxiliary lamp, and the weight of the storage device is not increased and the operation is not complicated.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  First, an example of an auxiliary lamp storage device to which the present invention is applicable is shown in FIGS.

  FIG. 4A is a side view showing a cargo loading portion at the rear of the fuselage aircraft. The cargo door 2 and the lamp door 3 are provided side by side at the cargo loading / unloading exit, the cargo door 2 is rotated upward by the driving device 1a, and the lamp door 3 is expanded downward by the driving device 1b. The cargo loading / unloading exit is opened.

  The auxiliary lamp 4 attached to the front end portion of the lamp door 3 fills the step between the lamp door 3 and the ground surface so that the vehicle or the like can run smoothly. A storage position of the auxiliary lamp 4 is provided on the cargo door 2 in the machine.

  FIG. 4B shows the relationship between the lamp door 3 and the auxiliary lamp 4 attached to the tip portion thereof. An auxiliary lamp 4 is attached to the front end of the lamp door 3. The auxiliary lamp 4 is rotatably supported by an actuator 5 attached to the tip of the lamp door 3, and cargo is carried in and out in a state where the auxiliary lamp 4 is deployed on the extension of the lamp door 3.

  When the lamp door 3 is stored, as shown in FIGS. 5A and 5B, the lamp door 3 is rotated upward and stored with the auxiliary lamp 4 standing on the lamp door 3. The

  When the auxiliary lamp 4 is stored, the auxiliary lamp 4 is removed from the lamp door 3 after the auxiliary lamp 4 is tilted to the cargo door 2 side as shown in FIG. Subsequently, as shown in FIG. 5 (d), the auxiliary lamp 4 is slid by hand to the storage position on the cargo door 2. With the auxiliary lamp 4 housed in this manner, the lamp door 3 is opened during the flight to drop in the air, or the cargo is loaded directly through the lamp door 3 at a base equipped with a dedicated transport facility. The carry-out is performed.

  6 and 7 show an auxiliary lamp storage device that slides the auxiliary lamp 4 to a storage position on the cargo door 2. In this auxiliary lamp storage device, first and second rollers (first and second followers) 7 and 8 are provided on both sides of the auxiliary lamp 4, while a pair of guide plates 6 are provided on the cargo door 2. Each guide plate 6 is formed with first and second travel slits 10 and 20 for rolling contact of the first and second rollers 7 and 8. As the auxiliary lamp 4 is turned to the first and second traveling slits 10 and 20 side (clockwise direction in FIG. 6) with the end hinge 30 as a fulcrum, the first and second rollers 7 and 8 are moved. The entrances 11 and 21 of the first and second travel slits 10 and 20 are entered. In this way, with the first and second rollers 7 and 8 placed on the first and second rails 12 and 22 of the first and second traveling slits 10 and 20, the coupling pin (not shown) is pulled out to the end of the lamp door 3. Separate the auxiliary lamp 4 from the hinge. The auxiliary lamp 4 causes the first and second rollers 7 and 8 to roll into contact with the first and second rails 12 and 22 of the first and second traveling slits 10 and 20, and against cargo by human power. It slides as if it is pushed up obliquely to the storage position on the door 2.

  However, in this auxiliary lamp storage device, the first and second rails 12 and 22 of the first and second traveling slits 10 and 20 provided on the cargo door 2 are arranged along the cargo door 2 with the lamp door 3. Since it is inclined upward from the connection position to the storage position, a large force is required to slide the auxiliary lamp 4 so as to push it up against the gravity at the time of storage. was difficult.

  Furthermore, when the auxiliary lamp 4 is slid from the storage position to the connecting position, the auxiliary lamp 4 comes down vigorously due to gravity. In order to prevent this, it is necessary to support the auxiliary lamp 4 against gravity against human power. Yes, it requires a lot of power and it is difficult to ensure safety.

  In addition, when a winch or the like is used to slide the auxiliary lamp 4 to the storage position, there is a problem that the weight of the storage device is increased and the operation is complicated.

  The present invention has been made paying attention to the above-mentioned problems, and provides an auxiliary lamp storage device that can move the auxiliary lamp easily and safely. Hereinafter, an embodiment of the auxiliary lamp housing apparatus shown in FIG. In addition, the same code | symbol is attached | subjected to the same structure part as the above-mentioned auxiliary lamp storage apparatus.

  FIG. 1 shows the auxiliary lamp storage device of the present invention in which the auxiliary lamp 4 is slid to the storage position on the cargo door 2. This auxiliary lamp storage device is provided with first and second rollers 7 and 8 as first and second followers arranged in the longitudinal direction on both sides of the auxiliary lamp 4, while a pair of guide plates on the cargo door 2. 6, and first and second traveling slits 10 and 20 are formed in each guide plate 6 for rolling contact of the first and second rollers 7 and 8.

  The first traveling slit 10 includes a first inlet 11 that opens to the upper end surface of the guide plate 6 and a first rail 12 that extends in a substantially horizontal direction.

  The second traveling slit 20 includes a second inlet 21 that opens to the upper end surface of the guide plate 6, a second rail 22 that extends in a substantially horizontal direction, and a latch that extends by bending upward from a terminal portion of the second rail 22. And a recess 23. The locking recess 23 is recessed facing the terminal end of the second rail 22, and engages the second roller 8 that rotates by gravity acting on the auxiliary lamp 4.

  As will be described later, the storage operation of the auxiliary lamp storage device is as follows. As the auxiliary lamp 4 is tilted toward the first and second traveling slits 10 and 20 with the end hinge 30 as a fulcrum, the first roller 7 is moved to the first position. The second roller 8 comes into contact with the second rail 22 as the auxiliary lamp 4 is brought to the cargo door 2 side with the first roller 7 as a fulcrum. 8 is brought into sliding contact with the first and second rails 12 and 22 and is slid to the storage position on the cargo door 2.

  The auxiliary lamp 4 is formed such that its center of gravity G is positioned in front of the first roller 7. Thereby, when the auxiliary lamp 4 rotates about the first roller 7 by gravity, a moment acts in the counterclockwise direction in FIG. The second roller 8 is engaged with the locking recess 23 by this moment.

  The auxiliary lamp 4 may be formed so that the center of gravity G is positioned in the vicinity of the first roller 7. Further, the auxiliary lamp 4 may be formed such that the center of gravity G is located behind the first roller 7 (on the cargo door 2 side). In that case, since the auxiliary lamp 4 is rotated in the clockwise direction by gravity, the engaging recess 23 may be formed to bend and extend downward from the terminal end of the second rail 22.

  A pedestal 29 is provided on the cargo door 2. As shown in FIG. 1, the auxiliary lamp 4 has its lower surface in contact with the pedestal 29, and the lug block 40 of the auxiliary lamp 4 ends with the first roller 7 in contact with the front end of the first rail 12. The hinge 30 is engaged.

  As shown in FIGS. 2A, 2 </ b> B, and 2 </ b> C, the end hinge 30 is rotatably connected to the lamp door 3 via a coupling pin 31. The end hinge 30 is driven with respect to the lamp door 3 by a hydraulic cylinder (not shown), deploys and stores the auxiliary lamp 4 with respect to the lamp door 3, and develops the upper position and the lower position with respect to the upper surface of the lamp door 3. It will be switched to the state. The structure for driving the end hinge 30 has already been filed as Japanese Patent Application No. 2003-59059 by the present applicant.

  The end hinge 30 has upper and lower convex portions 32 and 33, while the lug block 40 has a convex portion 42 and a movable lug plate 43 that engage with the lug block 40, and a connecting pin 39 penetrating each hole formed therein. Is provided.

  The lug plate 43 is rotatably supported by the lug block 40 via lug operation pins 44. The lug plate 43 is rotated between the engagement position indicated by the solid line in FIGS. 2A and 2C and the release position indicated by the two-dot chain line via the lug operation pin 44. A ball plunger 46 is provided to hold the lug plate 43 in the engagement position and the release position.

  Note that a movable lug plate may be provided in place of the convex portion 42 of the lug block 40 so that both the convex portion 42 and the lug plate 43 can rotate. Further, a movable lug plate may be provided on the end hinge 30 side.

  When the auxiliary lamp 4 is used, the connecting pin 39 passes through the upper and lower convex portions 32 and 33 of the end hinge 30, the convex portion 42 of the lug block 40, and the lug plate 43, thereby connecting the auxiliary lamp 4 to the lamp door 3. . On the other hand, when the auxiliary lamp 4 is rotated from the connection position to the storage position when the auxiliary lamp 4 is stored, the connecting pin 39 is removed and the lug plate 43 is rotated to the release position, whereby the lamp door 3 and the auxiliary lamp are rotated. 4 is released, and the auxiliary lamp 4 can rotate toward the cargo door 2 with the first roller 7 as a fulcrum.

  (A), (b), (c), and (d) of FIG. 3 show the operation of moving the auxiliary lamp 4 to the storage position on the cargo door 2, which will be described below.

  1. As shown in FIG. 2A, the first and second rollers 7 and 8 are moved to the first and second traveling slits as the auxiliary ramp 4 is tilted toward the cargo door 2 with the end hinge 30 as a fulcrum. Enter 10 and 20 entrances 11 and 12. At this time, the auxiliary roller 4 is placed on the cargo door 2 with the first roller 7 contacting the front end of the first rail 12 and the lower surface contacting the pedestal 29, and the connecting pin 39 is removed. Then, the lug plate 43 is rotated to the release position to release the connection between the lamp door 3 and the auxiliary lamp 4.

  2. Subsequently, as the auxiliary lamp 4 is tilted toward the cargo door 2 with the first roller 7 as a fulcrum, the second roller 8 comes into contact with the second rail 22.

  3. The first and second rollers 7 and 8 are slid to the storage position on the cargo door 2 by human power while being brought into rolling contact with the first and second rails 12 and 22.

  4). The auxiliary lamp 4 rotates with the first roller 7 as a fulcrum by gravity, and the second roller 8 is engaged with the locking recess 23. As a result, the auxiliary lamp 4 is locked at the storage position on the cargo door 2, and the auxiliary lamp 4 does not rise or move forward.

  With the above configuration, when the auxiliary lamp 4 is stored, the first roller 7 comes into contact with the first rail 12 as the auxiliary lamp 4 is tilted toward the cargo door 2 with the end hinge 30 as a fulcrum. The second roller 8 is brought into contact with the second rail 22 as the auxiliary lamp 4 is tilted toward the cargo door 2 with the first roller 7 in contact with the first rail 12 as a fulcrum. The inclination angle of the second rails 12 and 22 is not determined by the posture of the auxiliary lamp 4 at the connection position, and the first and second rails 12 and 22 extend substantially horizontally from the connection position with respect to the lamp door 3 to the storage position. Can be formed. Since the first and second rails 12 and 22 extend substantially horizontally, a large force is not required when the auxiliary lamp 4 is slid against gravity during storage, and one worker can easily work. Can do.

  On the other hand, when the auxiliary lamp 4 is used, the operation is substantially the reverse of that when the auxiliary lamp 4 is stored. Also in this case, since the first and second rails 12 and 22 extend substantially horizontally, the auxiliary lamp 4 comes down vigorously due to gravity when the auxiliary lamp 4 is slid from the storage position to the connection position. This work can be done safely.

  Further, it is not necessary to use a winch or the like to slide the auxiliary lamp 4, so that the weight of the storage device is not increased and the operation is not complicated.

  Further, as the first and second followers provided in the auxiliary lamp 4, for example, pins or the like may be provided instead of the first and second rollers 7 and 8.

  The present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within the scope of the technical idea.
