Description

  The present invention relates to an aircraft transport container mounted in an aircraft cargo space and a method for loading cargo onto an aircraft using the same.

  In order to load loads into the cargo space of a large aircraft, an air container of a certain standard for loading individual loads is used (see Patent Document 1, etc.). A large aircraft has a large cargo space, and a large hatch is provided for loading and unloading the cargo space, and an opening for loading and unloading the cargo is also large. Therefore, the cargo can be loaded by loading the cargo in the air container, and sequentially loading and loading the air container in the cargo space using a dedicated machine.

  On the other hand, in a small aircraft, the cargo space is narrowed, the hatch for loading / unloading luggage is also small, and the opening for loading / unloading luggage is small. In addition, a large aircraft has a structure in which a hatch is largely opened, whereas a small aircraft generally has a structure in which a hatch is opened inward. Therefore, the hatch that opens inward is in the cargo space, and accordingly, it becomes difficult to put tall cargo into the cargo space. Under these circumstances, in a small aircraft, a standard product ULD (Unit Load Device) conventionally used as an air container cannot be carried into a cargo space. In the text, the term “small aircraft” means a standard ULD that cannot be carried into the cargo space. As a standard ULD, for example, what is called LD-3 is used, which has a height of about 1410 mm and a width of about 1400 mm, and cannot be carried in by a hatch of a small aircraft.

  Therefore, in small aircraft, the baggage is transported as it is to the hatch with a belt conveyor, etc., and the workers manually carry the baggage into the cargo space one by one through the opening of the hatch that opens inward. While the workers keep the middle posture in the cargo space, they load the packages one by one by hand. These operations are very hard work for workers and require time to complete. In addition, since the workers manually load the luggage in the narrow cargo space, whether or not the space can be loaded effectively by using the space depends on the skill and the number of workers.

  In recent years, needs for freight transportation by small aircraft have increased, and it is desired to reduce the above-mentioned heavy labor and to improve work efficiency.

Japanese Utility Model Publication No. 63-180595

  The present invention has been invented in view of the above-mentioned problems, and it is possible to easily and efficiently load a small aircraft with a narrow cargo space, a small hatch and a small opening. An object of the present invention is to provide an aircraft transport container that can be used and a method for loading cargo on an aircraft using the same.

  The present invention is an aircraft transport container to be loaded in a cargo space of a small aircraft, and includes a container body having a bottom plate and a plurality of side plates standing from the end of the bottom plate, and is flat on the upper surface of the bottom plate.

  It is preferable that the container main body has an upper surface opening through which a load can be taken in and out, further includes a cover plate that closes the upper surface opening, and the second loading surface is provided on the upper surface of the cover plate.

  Furthermore, it is also preferable that the container body is provided in a substantially ship shape by providing a part and the other part of the bottom plate so as to be separated from each other toward the top.

  The present invention is also a luggage loading method for loading luggage into a cargo space of a small aircraft using an aircraft transport container having the above-described configuration, with the luggage loaded in advance on the first loading surface. The container main body is loaded in a cargo space, and then another cargo is sequentially loaded on the second loading surface in the cargo space in which the container main body is loaded.

  The present invention also relates to a load loading method for loading a load into a cargo space of a small aircraft using an aircraft transport container provided with the lid plate, wherein the load is loaded in advance on the first load surface of the container body. With the lid closed, the container body is transported together with the container body to the vicinity of the small aircraft, the machine transported container body is loaded in the lower area in the cargo space, and the container body is loaded. In the upper region in the cargo space, another cargo is loaded on the second loading surface.

  The present invention makes it possible to load cargo easily and efficiently by using a new air transport container for a small aircraft having a small cargo space, a small hatch and a small opening. There is an effect.

  The present invention will be described based on embodiments shown in the accompanying drawings. The aircraft transport container of the present embodiment is an aircraft transport container A mounted in the lower region of the cargo space S. In this embodiment, this aircraft transport container A is used in a form combined with a transport container B mounted in the upper region of the cargo space S.

  1 to 4 show an aircraft transport container A, and FIGS. 5 to 8 show a transport container B. In FIG. 11, the laminated resin board 2 used in common for the aircraft transport container A and the transport container B is shown.

  First, the structure of the aircraft transport container A will be described. As shown in FIG. 1 and FIG. 2, the aircraft transport container A includes a container body 4 having a ship shape and a lid plate 6 attached so as to close the upper surface opening of the container body 4. The cover plate 6 prevents rain or the like from entering the container body 4.

  The container body 4 includes a bottom plate 8 having a shape in which one end portion and the other end portion in the longitudinal direction a are bent obliquely upward, and a pair of side plates 10 connected to the end edge portion in the short direction b of the bottom plate 8. Have. In the present embodiment, the bottom plate 8 is formed by using a horizontal bottom plate 12 having a rectangular shape in plan view, and a pair of inclined bottom plates 16 connected to both edge portions of the horizontal bottom plate 12 using hinge members 14. Yes.

  In the aircraft transport container A of the present embodiment, each of these plate members 6, 10, 12, and 16 is formed using the laminated resin plate material 2. The laminated resin plate 2 has a structure shown in FIG. 11, and a hollow structure plate 18 made of polypropylene (hereinafter abbreviated as “PP”) is used. The hollow structure plate 18 is a plate material having a structure in which a honeycomb core material 20 in which hollow hexagonal columns are arranged side by side without any gap is sandwiched by a pair of skin materials 22 from both sides. This honeycomb structure hollow structure plate 18 has a very high strength per unit weight, is excellent in mechanical properties and isotropic, and is also excellent in secondary workability because it is made of a thermoplastic resin.

  In the laminated resin plate material 2, a synthetic resin fiber sheet 24 is bonded to the outer surface of the skin material 22 on both sides of the hollow structure plate 18, and a resin sheet 26 is further bonded so as to cover the outer surface of the fiber sheet 24. Attached. In this case, a binder resin made of polyethylene (hereinafter abbreviated as “PE”) is used, but it may be attached by other means such as an adhesive sheet or a heat laminate.

  The fiber sheet 24 is formed by combining synthetic resin composite fibers arranged in one direction, using synthetic resin stitch yarns, and further pressing to form a bowl-like sheet. A plurality of sheets are stacked and formed into a single sheet by heat and pressure molding. The composite fiber is obtained by covering a core component made of PP with a sheath component made of PE having a lower melting point than this, and the stitch yarn is made of polyester. In this embodiment, three sheet-like sheets are used, and each sheet is laminated so that the arrangement direction of the fibers is different by 30 degrees, thereby forming a multiaxial fiber sheet. By heating and pressing, the sheath component having a low melting point of the composite fiber is melted or softened and flattened, thereby increasing the integrity of the entire sheet and improving the strength. In addition to the multiaxial fiber sheet, the fiber sheet 24 may be a woven fabric, a knitted fabric, a nonwoven fabric, or a combination thereof.

  The resin sheet 26 that is the outermost layer of the laminated resin plate 2 is a thin-film PP sheet. The resin sheet 26 is formed to be thinner than the hollow structure plate 18. The resin sheet 26 and the fiber sheet 24 may be provided with the same thickness. However, when the resin sheet 26 is formed thinner than the fiber sheet 24, the weight can be further reduced.

  That is, the laminated resin plate material 2 has a structure in which a honeycomb structure hollow structure plate 18 made of a synthetic resin is further sandwiched from both sides by a synthetic resin fiber sheet 24 and further sandwiched by resin sheets 26 from both sides. . By covering with the resin sheet 26, the effect of improving the bending strength and bending rigidity of the entire laminated resin plate 2 and the effect of making it difficult for dust and dirt to adhere to the resin sheet 26 can be obtained. The hollow structure plate 18 has a hollow structure other than the honeycomb structure (for example, a hollow structure in which a large number of flat partition walls are arranged in one direction like a harmonica, or a large number of hollow truncated cones and cylinders arranged in parallel. Or a hollow structure in which a large number of columnar bodies having a shape in which the upper and lower surfaces of a pair of hollow truncated cones are attached to each other may be used.

  The horizontal bottom plate 12 that forms the central portion of the bottom plate 8 is molded using this laminated resin plate material 2. This horizontal bottom plate 12 forms a concave step portion 28 by crushing the lower surface side of both edge portions in the longitudinal direction a, and the bent piece portions 30 are formed on both edge portions in the short direction b by hot bending welding. It is formed by bending upward. By crushing the edge portion of the laminated resin plate material 2, the effect of improving the strength due to the occurrence of the resin pool can be obtained. The heat bending of the laminated resin plate material 2 may be performed by crushing and bending the portion closer to the front side than the outer fiber sheet 24 to be bent, or crushing the portion of the outer fiber sheet 24 up to the middle in the thickness direction. May be bent.

  The upper surface of the horizontal bottom plate 12 becomes the first loading surface 70 of the aircraft transport container A. The first loading surface 70 is a flat surface having a rectangular shape in plan view having four sides in the longitudinal direction a and the short direction b of the bottom plate 8, and by loading a load on the first loading surface 70, the aircraft transport container A A package is loaded in the container body 4.

  The inclined bottom plate 16 forming both ends of the bottom plate 8 is similarly molded using the laminated resin plate material 2. The inclined bottom plate 16 forms a hinge structure 34 in the vicinity of one edge in the longitudinal direction a by heat ruled line processing from the inner surface side. The thermal ruled line processing for the hinge structure 34 may be a method of crushing up to a portion closer to the front side than the outer fiber sheet 24, or a method of crushing a portion of the outer fiber sheet 24 up to the middle in the thickness direction. There may be.

  In the laminated resin plate material 2, PP is used as the material of the hollow structure plate 18 and the fiber sheet 24, so that problems such as peeling are less likely to occur when performing hot bending welding processing or thermal ruled line processing. . In addition, the hollow structural plate 18 is crushed when performing the heat bending welding process or the heat ruled line process, and the synthetic resin accumulates in the hollow portion of the crushed surface, so that the effect of welding is reliably performed and the strength is increased. The effect of increasing is also obtained.

  A bent piece 36 is formed by bending upward at both end edges in the short direction b of the inclined bottom plate 16 by hot bending welding. V-shaped cutouts are provided at locations corresponding to both ends of the hinge structure 34 in the bent piece 36. Further, a pair of handle holes 40 are formed through the inclined bottom plate 16 so as to penetrate therethrough.

  The side plate 10 is formed into a substantially inverted trapezoidal shape using the laminated resin plate material 2. A pair of handle holes 42 similar to those of the inclined bottom plate 16 are also formed in the side plate 10 so as to penetrate therethrough. The handle holes 40 and 42 may be concave as long as they do not penetrate. Moreover, you may form a handle part by attaching another site | part of the shape where it penetrated or was depressed.

  The lid plate 6 is formed in a flat plate shape using the laminated resin plate material 2. The cover plate 6 has a substantially rectangular outer shape in plan view, and is formed by bending the bent piece portions 44 downward at both end edges in the longitudinal direction a by hot bending welding. In addition, a bent piece portion 46 is also formed by bending downward at one end edge of the cover plate 6 in the short direction b by a similar thermal bending welding process. A concave step portion 48 is formed on the other end edge of the cover plate 6 in the short direction b by crushing the upper surface side.

  In addition to these plate members 6, 10, 12, and 16, the hinge member 14 shown in FIG. 3, the frame member 52 shown in FIG. 4, the corner member 54 shown in FIGS. 1 and 2, the rivet member (not shown), etc. The aircraft transport container A is assembled by using another member.

  The hinge member 14 is a member that connects the end edges of the laminated resin plate 2 so as to be bendable. The hinge member 14 has a U-shaped hinge half 56 that is fitted and fixed to the end of the one laminated resin plate 2. The corner edge portion and the corner edge portion of the hinge half portion 58 having a U-shaped cross-section that is fitted and fixed to the end edge portion of the other laminated resin sheet material 2 are connected via an elastically deformable connection portion 60. Is. The hinge halves 56 and 58 on both sides are formed into a long shape using PP, and the connecting portion 60 is formed using an elastomer.

  The frame member 52 is a long member having a U-shaped cross section that is fitted and fixed to the end edge portion of the laminated resin plate material 2 and is molded using PP. The corner member 54 is an L-shaped member in plan view, and is formed in a U-shaped cross section so as to be further fitted to the attached frame member 52 from above. The hinge member 14, the frame member 52, and the corner member 54 are formed with dimensions and shapes according to respective installation locations. Since each of these members 14, 52, 54 and the laminated resin plate material 2 are formed using a thermoplastic resin, they can be recycled. In particular, since PP is mainly used, they can be used for pallets and the like.

  It is also possible to assemble the aircraft transport container A without using these members 14, 52, 54. In this case, after the plate members 6, 10, 12 and 16 are integrally formed using the laminated resin plate material 2, the hinge structures 34 and the like are formed at the boundary portions, and then the portions are folded and joined together. Assemble transport container A. According to this, a separate member such as the hinge member 14 becomes unnecessary, and the inner surface and the outer surface of the aircraft transport container A are formed flat as a whole. The end surface treatment of the laminated resin plate material 2 is performed by crushing or crushing and bending the end surface. Resin can be accumulated by this end face treatment, and the effect of improving the strength can also be obtained. In addition, since a step due to the mounting of the frame member 52 or the like does not occur, a flatter appearance can be obtained.

  More specifically, the aircraft transport container A is assembled as follows.

  In the bottom plate 8, one hinge half 56 of the hinge member 14 is fitted into the pair of concave steps 28 of the horizontal bottom plate 12 at both ends, and the other hinge half 58 of the hinge member 14 is inclined to the bottom plate. By being fitted to the 16 edge portions, one end and the other end in the longitudinal direction a are assembled into a shape like a ship bottom that is bent obliquely upward.

  Here, since the thickness of the plate portion of the hinge half portion 56 is set to be the same as the depth of the concave step portion 28, the hinge half portion 56 is fitted in the concave step portion 28. The lower surface of the part 56 and the lower surface of the horizontal bottom plate 12 are made flat and continuous (see FIG. 2). As a result, the bottom surface of the container main body 4 becomes flat and is less likely to be damaged during movement. The depth of the recessed step portion 28 may be formed slightly shallower than the thickness of the plate portion of the hinge half 56 or may be formed deeper. In order to make the sliding smooth, a leg portion like a warp may be formed on the bottom surface of the container body 4.

  A concave step similar to the concave step 28 may be provided on the upper surface side of the horizontal bottom plate 12. By fitting the upper plate portion of the hinge half portion 56 into the concave step portion on the upper surface side, the inner surface of the container body 4 becomes flatter and the contents are prevented from being caught. Of course, even when the concave step portion is not provided on the upper surface side of the horizontal bottom plate 12, the plate portion of the hinge half portion 56 is thin, so that the generated step is small and the contents are hardly caught.

  The inclined bottom plate 16 is further bent at its upper portion 17 via a hinge structure 34, and the side plates 10 on both sides are fixed to the bottom plate 8 with the upper portion 17 standing upright. The bottom plate 8 and the side plate 10 are fixed by fixing the bent piece portions 30 and 36 provided on the horizontal bottom plate 12 and the inclined bottom plate 16 and the edge of the side plate 10 with a rivet member.

  A frame member 52 having a length corresponding to this portion is fitted to the upper end edge of the upper portion 17 of the inclined bottom plate 16 from above. Similarly, a frame member 52 having a length corresponding to this portion is fitted to the upper end edge of one side plate 10 from above.

  A hinge half portion 58 of the hinge member 14 formed in a length dimension for the lid is fitted to the upper edge of the other side plate 10, and the other hinge half portion 56 of the hinge member 14 is fitted to the lid plate 6. The concave step 48 is fitted. Thereby, the container main body 4 and the cover plate 6 are rotatably connected.

  Since the thickness of the plate portion of the hinge half portion 56 is set to be the same as the depth of the recessed step portion 48 of the cover plate 6, the hinge half portion 56 is fitted in the recessed step portion 48. The upper surface of the hinge half 56 and the upper surface of the cover plate 6 are made flat and continuous (see FIG. 1). The depth of the recessed step portion 48 can be formed slightly shallower or deeper than the thickness of the plate portion of the hinge half 56.

  Further, L-shaped corner members 54 are attached to the four corners of the opening edge of the container body 4 from above the frame member 52. Thereby, the inclined bottom plate 16 and the side plate 10 of the bottom plate 8 are firmly coupled, and the container body 4 is reinforced.

  When the cover plate 6 is closed, the bent piece portions 44 and 46 of the cover plate 6 come into contact with the corresponding frame member 52 from the outside. It is also preferable to provide a hook and loop fastener for temporarily fixing the cover plate 6 in a closed state on both the bent piece portions 44 and 46 and the frame member 52 at a corresponding position. Further, in order to temporarily fix the lid plate 6 in the closed state, other temporary fixing means such as a buckle may be provided.

  The upper surface of the cover plate 6 becomes the second loading surface 72 of the aircraft transport container A. The second stacking surface 72 is a flat surface having a rectangular shape in plan view having four sides in the longitudinal direction a and the short direction b of the bottom plate 8, and is positioned directly above the first stacking surface 70 with the cover plate 6 closed. To do.

  The second stacking surface 72 is the same as or substantially the same as the first stacking surface 70 in the length dimension in the short direction b, and is longer than the first stacking surface 70 in the length dimension in the longitudinal direction a. About 3 times larger. That is, the second stacking surface 72 is positioned in parallel with the first stacking surface 70 located immediately below the second stacking surface 72 and has a large area about 2.3 times that of the first stacking surface 70. On the second loading surface 72, the package is loaded on the container body 4 of the aircraft transport container A by directly loading the package with the package loaded with the package B or the package.

  In the aircraft transport container A having such a structure, the hollow portions of the hollow structure plate 18 are exposed at the end surfaces of the bent piece portions 30, 36, 44, 46. Since it is an independent cell, even if trash is collected, only a small amount is required. In order to prevent dust from accumulating on the end surfaces of the bent piece portions 30, 36, 44, 46, the end surfaces can be closed by crushing the end surfaces or applying an edge tape.

  The configuration of the aircraft transport container A of the present embodiment has been described above. Next, the configuration of the transport container B will be described. Note that a part of the description of the same configuration as that of the aircraft transport container A is omitted.

  As shown in FIG. 5 as a whole, the transport container B includes a box-shaped container main body 104 having an open top surface and a lid plate 106 attached so as to close the opening of the container main body 104.

And a pair of second side plates 112 connected in series.

  Also in the transport container B, these plate members 106, 108, 110, and 112 are formed using the laminated resin plate material 2 similar to the transport container A for aircraft. The structure of the laminated resin sheet 2 is as described above with reference to FIG.

  In the transport container B, the bottom plate 108 and the pair of first side plates 110 are integrally formed using the laminated resin plate material 2 (see FIG. 6). Specifically, both end sides of a single laminated resin plate material 2 having a substantially rectangular shape in plan view are bent upward by hot bending welding, and a portion bent upward is defined as a first side plate 110. The bottom surface of the bottom plate 108 is flat and smoothly slides on the floor surface.

  The upper surface of the bottom plate 108 becomes a flat loading surface 170 that the transport container B has. The loading surface 170 is a flat surface having a rectangular shape in plan view having four sides in the longitudinal direction a and the short direction b, and loads are loaded on the container body 104 of the transport container B by placing the loads on the loading surface 170. Is done. The loading surface 170 is the same as or substantially the same as the first loading surface 70 and the second loading surface 72 of the aircraft transport container A in the length dimension in the short direction b, and in the length dimension in the longitudinal direction a. It is set to be about half of the second loading surface 72 of the aircraft transport container A.

  The first side plate 110 is formed with three hinge structures 134 by heat ruled line processing from the inner surface side. The three hinge structures 134 are formed in parallel lines spaced apart in the vertical direction, and the distance between the lower and central lines of the hinge structure 134 and the distance between the central and upper lines are determined. Are set identically.

A block between the structure 134 and the upper hinge structure 134 will be described as a movable upper plate 120, and a block above the upper hinge structure 134 will be described as an upper end side plate 122. Of these, the movable lower plate 118 and the movable upper plate 120 are refracted in a “<” shape, whereby the entire first side plate 110 is folded up and down.

  Each of the blocks 116, 118, 120 excluding the top plate 122 of the bottom plate 108 and the first side plate 110 is a bent piece portion that is bent inward by thermal bending welding from both end edges in the longitudinal direction a. 124 is provided. Each bent piece 124 has a corner portion cut obliquely so as not to interfere with each other.

  The second side plate 112 is formed into a rectangular shape as shown in FIG. 7 using the laminated resin plate material 2. On the second side plate 112, a hinge structure 134 by heat ruled line processing similar to that of the first side plate 110 is formed in a straight line at a location near the upper edge.

  In the following, the block above the hinge structure 134 in the second side plate 112 will be described as the upper end side plate 126, and the block below the hinge structure 134 will be described as the swing side plate 128. The swing side plate 128 has a pair of handle holes 142 formed therethrough. When the swing side plate 128 is bent inward via the hinge structure 134, the entire second side plate 112 is folded.

  The lid plate 106 is molded using the laminated resin plate material 2. The lid plate 106 has a substantially rectangular outer shape in plan view, and is provided with bent piece portions 144 that are bent downward by thermal bending welding at both end edges in the longitudinal direction a. Further, a bent piece portion 146 that is bent downward by a similar thermal bending welding process is also provided at one end edge of the cover plate 106 in the short direction b. A concave step 148 is formed on the other end edge of the cover plate 6 in the short direction b by crushing the upper surface.

  The transport container B is assembled by using the above-described members, the hinge member 114, the frame member 152, the corner member 154, and the like.

  The hinge member 114 has the same structure as that of the hinge member 14 used in the aircraft transport container A, and the corner portions of the pair of hinge halves 156 and 158 having a U-shaped cross section can be elastically deformed. It is connected via.

  The frame member 152 and the corner member 154 also have the same structure as the frame member 52 and the corner member 54 used in the aircraft transport container A, and are formed in dimensions and shapes corresponding to the respective installation locations.

  More specifically, the transport container B is assembled as follows.

  As shown in FIG. 5 and the like, a frame member 52 having a length corresponding to this portion is fitted from above to upper end edges of the pair of second side plates 112 (that is, upper end edges of the upper end side plates 126).

  A frame member 152 having a length corresponding to this portion is fitted from above to one upper end edge of the pair of first side plates 110 erected from the bottom plate 108 (that is, the upper end edge of the upper end side plate 122). One hinge half 158 of the hinge member 114 is fitted to the upper edge of the other first side plate 110, and the other hinge half 156 of the hinge member 114 is connected to the concave step 148 of the lid plate 106. Mated. Thereby, the 1st side board 110 and the cover board 106 are connected rotatably.

  The thickness of the hinge half 156 is such that the upper surface of the hinge half 156 and the upper surface of the cover plate 106 are flat in a state where the hinge half 156 is fitted to the concave step 148 of the cover plate 106. (See FIG. 5).

  The first side plate 110 and the second side plate 112 are connected to each other at the upper end side plates 122 and 126 via a corner member 154 and the like fitted from above. When the lid plate 106 is closed, the bent piece portions 144 and 146 included in the lid plate 106 come into contact with the corresponding frame member 152 from the outside. As with the aircraft transport container A, it is preferable to provide temporary fixing means such as hook-and-loop fasteners on the bent piece portions 144 and 146 and the frame member 152.

As shown in FIG. 8B, first, the swing side plate 128, which is the lower block, of the second side plate 112, which is the short side of the container body 104, is bent inward with the hinge structure 134 as the center. Next, as shown in FIG. 8 (c), the movable lower plate 118 and the movable upper plate 120 of the first side plate 110, which is the long side of the container main body 104, are used by using the hinge structures 134 at three positions, Refracted in a "<" shape toward the inside. As a result, the entire transport container B is folded up and down as shown in FIG. 8D, and the volume can be reduced to about 1/3.

  FIG. 9 shows a state where the aircraft transport container A and the transport container B having the above-described structure are mounted in the cargo space S of the aircraft.

  In the aircraft, the upper half of the fuselage is used for the passenger cabin, and the lower half of the fuselage is used for the cargo space S. For this reason, the cargo space S of an aircraft is usually a semicircular space with a cross-section on the upper side as shown.

  The aircraft transport container A and the transport container B of the present embodiment are set in dimensions and shapes corresponding to the specific shape of the cargo space S of the small aircraft. In other words, in the standard ULD, the cargo space S This is a specially designed aircraft transport container for small aircraft that cannot be carried in. However, the transport container B can be used for other purposes.

  As shown in FIG. 10, the dimension in the longitudinal direction a of the entire aircraft transport container A is set to be twice the dimension in the longitudinal direction a of the entire transport container B. The transport container A for aircraft has a substantially ship-like shape as a whole, and the transport container B has a box shape as a whole. Therefore, the transport container B has a dimension in the longitudinal direction a of the cover plate 6 of the aircraft transport container A. It is set to be double or substantially double the size of the main body 104 and the cover plate 106 in the longitudinal direction a.

  On the other hand, the aircraft transport container A and the transport container B have the same or substantially the same length in the short direction b. That is, the dimension in the short direction b of the cover plate 6 included in the aircraft transport container A is set to be the same or substantially the same as the dimension in the short direction b of the container main body 104 and the cover plate 106 included in the transport container B. .

  Therefore, two transport containers B are placed in close contact with or close to the longitudinal direction a on the cover plate 6 of one aircraft transport container A, and the transport container A and the transport container A mounted in such an arrangement are transported. The entire set of containers B (see FIG. 9) is specially designed to fit into a semicircular cargo space S whose upper side is a chord through a slight gap.

  By carrying the set of the transport container A and the transport container B for the aircraft continuously in the short direction b (that is, the depth direction of the cargo space S), the cargo space S having a semicircular cross section is effectively used. Can be loaded.

  The aircraft transport container A and the transport container B are loaded in advance and the lid plates 6 and 106 are closed. In this state, the transport container A and the transport container B are mechanically transported to the hatch opening using a belt conveyor or the like. The operator first places the aircraft transport container A on the floor surface in the lower region of the cargo space S. At this time, the flat second loading surface 72 of the lid plate 6 included in the aircraft transport container A and the flat upper surface of the hinge half portion 58 attached to the lid plate 6 are flush with each other in the short direction b. In position.

  Next, when the transport container B is mounted using the upper region of the cargo space S, the transport container B can be loaded while being shifted using the flat continuous surface of the transport container A for aircraft. it can.

  In addition, you may set the dimension of the longitudinal direction a of the container main body 104 and the cover board 106 which the transport container B has larger than the half of the dimension of the cover board 6 which the aircraft transport container A has in the longitudinal direction a. In this case, when the two transport containers B are placed in close contact or close to the longitudinal direction a on the second loading surface 72 on the cover plate 6 of the transport container A for aircraft, the longitudinal direction of each transport container B One end of a is positioned to protrude outward from the end of the aircraft transport container A (see the imaginary line in FIG. 9). With this structure, a gap is less likely to be generated between the transport container B and the side wall of the cargo space S, and the area of the loading surface 170 of the transport container B is further increased.

  It is also possible to load a plurality of transport containers B in the upper region of the cargo space S after loading a plurality of aircraft transport containers A in the lower region of the cargo space S. In this case, the plurality of aircraft transport containers A are placed in close contact or close to each other in the depth direction on the floor surface of the cargo space S, so that the flat plate 6 of each aircraft transport container A is flat. A large number of the second loading surface 72 and the flat upper surface of the hinge half portion 58 attached to the lid plate 6 are successively positioned in the short direction b. When mounting the transport container B, use the flat continuous surface of these multiple transport containers A for aircraft as the transport surface and shift the transport container B to the back side and load them sequentially on this transport surface. Can do.

  Instead of the transport container B, luggage such as cardboard or trunk may be directly loaded. Since the aircraft transport container A is provided in a substantially ship-shaped dimension that fits with a slight gap with respect to the lower region of the cargo space S of the small aircraft, first, the aircraft transport container is transported to the lower region of the cargo space S. After the container A is set, the transport container B may be loaded on the upper area of the cargo space S by using the large-area second loading surface 72 formed on the upper part of the aircraft transport container A. Alternatively, the luggage may be loaded directly. At this time, since the transport container A for aircraft has a dedicated size and shape that fits in the lower region of the cargo space S with a slight gap, when the transport container B is placed on the transport container A for aircraft, When the transport container B is shifted and aligned on the container A, the aircraft transport container A serving as a base is prevented from being displaced. Therefore, it is easy to align the aircraft transport container A and the transport container B, and these can be neatly arranged in the cargo space S.

  In order to prevent the collapse of cargo during operation more reliably, it is preferable to appropriately pack a member in the gap in the cargo space S or to apply a load collapse prevention tool such as a rope or a net to the entire container. Further, a slip sheet (not shown) for wear prevention may be attached to the bottom surface of the container body 4 of the aircraft transport container A. By attaching the slip sheet to the bottom plate 8 of the container body 4 using a hook and loop fastener or the like, the slip sheet can be easily replaced when the slip sheet is consumed.

  As described above, the aircraft transport container A according to the present embodiment forms the container body 4 that opens upward from the bottom plate 8 and the plurality of side plates 10 that stand from the end of the bottom plate 8. 4 is an aircraft transport container including a cover plate 6 that closes four openings. And the laminated resin board material which affixes the fiber sheet 24 to both the one surface side and the other surface side of the synthetic resin hollow structure board 18 and the baseplate 8 and each side board 10 which make the container main body 4, and the cover board 6 2 is formed so that the fiber sheet 24 provided on each laminated resin plate 2 is arranged on the outer surface side and the inner surface side of the container.

  Similarly, the transport container B of the present embodiment is a container main body 104 opened upward by a bottom plate 108 and a plurality of side plates (first side plate and second side plate) 110 and 112 standing from the end of the bottom plate 108. This is an aircraft transport container provided with a cover plate 106 that forms a cover and closes the opening of the container body 104. Then, the bottom plate 108 and the side plates 110 and 112 constituting the container body 104 and the lid plate 106 are laminated by attaching the fiber sheet 24 to both one side and the other side of the hollow structure plate 18 made of synthetic resin. The resin sheet material 2 is used, and the fiber sheet 24 provided in each laminated resin sheet material 2 is formed so as to be disposed on the outer surface side and the inner surface side of the container.

  As described above, the laminated resin plate material 2 used in the aircraft transport container A and the transport container B of the present embodiment has a structure in which the fiber sheet 24 is attached to the lightweight and high-strength synthetic resin hollow structure plate 18. . Therefore, the weight of the entire container can be reduced to such an extent that the loading operation can be easily performed manually, and further, the entire container is increased in strength, and the container is deformed such that the container expands outward due to the load. Can not be. As a result, the loading operation can be quickly completed manually without using a dedicated machine. Moreover, since it is provided so that it does not swell easily while maintaining the strength of the entire container, it is less likely to slip during takeoff and landing.

  Moreover, since the fiber sheet 24 is affixed to the laminated resin plate material 2, even if the internal hollow structure plate 18 or the like is damaged, it is possible to prevent the fragments of the plate material from being scattered to the outside. In particular, the hollow structure plate 18 has a large number of thin partition walls that partition each cell, and there is a possibility that each partition wall becomes a fine fragment when broken, but this is because the fiber sheet 24 is attached. It is sufficient that the damaged portion is depressed via the fiber sheet 24. Even if the fiber sheet 24 is torn, the broken portion of the hollow structure plate 18 is dropped together with the fiber sheet 24, so that fine fragments are prevented from being scattered in the cargo space S. Therefore, it is suitably used as a transport container for mounting in the cargo space S of an aircraft.

  The laminated resin plate 2 of the aircraft transport container A and the transport container B may have a structure in which the fiber sheet 24 is attached only to one side of the hollow structure plate 18 and the other side. In this case, the fiber sheet 24 is formed so as to be arranged on the outer surface side of the transport container. Since the fiber sheet 24 is positioned on the outer surface side of the transport container, it is possible to suppress the fragments generated by the damage from being scattered outside the transport container.

  As described above in detail with reference to the accompanying drawings, the aircraft transport container A of the present embodiment is loaded into the cargo space S of a small aircraft, and stands from the bottom plate 8 and the end of the bottom plate 8. A container body 4 having a plurality of side plates 10 is provided. A flat first stacking surface 70 is provided on the upper surface of the bottom plate 8, and a flat second stacking surface 72 having a larger area than the first stacking surface 70 is provided above the first stacking surface 70. Yes.

  As described above, in a small aircraft, the cargo space S is narrow and the hatch opens inward so that the opening is small. Therefore, conventionally, an operator directly loads cargo into the cargo space S at an airport. It was loaded. On the other hand, by using the aircraft transport container A of the present embodiment, the aircraft transport container A is carried into the cargo space S with the cargo loaded on the first loading surface 70, and further the cargo space. On the second loading surface 72 of the aircraft transport container A mounted on the floor of S, other transport containers and packages can be loaded in the cargo space S. Therefore, labor is reduced for the worker, and the loading operation is completed in a short time. Further, if the aircraft transport container A is loaded in the cargo space S, the cargo space S is loaded with a load on the first loading surface 70 and loaded on the second loading surface 72. Therefore, it is possible to load the luggage using the narrow cargo space S effectively.

  The container body 4 has an upper surface opening through which a load can be taken in and out, further includes a cover plate 6 that closes the upper surface opening, and a second stacking surface 72 is provided on the upper surface of the cover plate 6.

  Accordingly, the lid plate 6 is closed to prevent rain and the like from entering the container body 4, and the upper surface when the lid plate 6 is closed is used as a flat second loading surface 72. It is possible to efficiently utilize the upper area of the space S as a space for loading luggage.

  Moreover, the container main body 4 is provided in the substantially ship shape by inclining and providing one part and other part of the baseplate 8 so that it may mutually separate so that it goes up.

  Thereby, in the cargo space S of a small aircraft, the transport container A for aircraft can be carried in so that it may fit in a small clearance, and the lower area | region of the narrow cargo space S can be utilized effectively. The aircraft transport container A as a whole has a substantially ship shape and a high center of gravity. Therefore, the aircraft transport container A can be easily carried to a predetermined position by slightly raising one side and shifting it on the floor surface. Then, the cover plate 6 that closes the upper surface opening of the container body 4 having a substantially ship shape can be provided with a large size. As a result, the second loading surface 72 formed of the upper surface of the cover plate 6 has a maximum area. Can be provided. Therefore, it becomes possible to load the cargo by making the best use of the entire narrow cargo space S.

  Further, in the luggage loading method in which the cargo is loaded into the cargo space S of the small aircraft using the aircraft transport container A of the present embodiment, the cargo is loaded together with the container body 4 with the luggage loaded on the first loading surface 70 in advance. In the cargo space S in which the container body 4 is loaded, other packages are sequentially loaded on the second loading surface 72. In this case, loading of other packages includes both a method of loading packages directly and a method of loading using a transport container such as transport container B.

  According to this method, labor is reduced for the worker, and the loading operation is completed in a short time. In addition, by such a simple operation, the entire cargo space S can be effectively used to load the cargo.

  Further, in the luggage loading method of loading luggage into the cargo space S of the small aircraft using the aircraft transport container A of the present embodiment, the luggage is loaded on the first loading surface 70 of the container body 4 in advance, and the lid plate With the container 6 closed, the entire container body 4 is mechanically transported to the vicinity of the small aircraft, and the container body 4 transported by machine is loaded in the lower area of the cargo space S, and the container body 4 is loaded in the cargo space S In the upper region, other loads are loaded on the second loading surface 72. Even in this case, loading of other packages includes both a method of loading packages directly and a method of loading using a transport container such as transport container B.
