Description

  The present invention is an outer box that loads small cargoes into units and mounts them in an aircraft cargo compartment, ULD (Unite Load Device), and loads the cargo units on a pallet and assembles the cargo units using curing materials. The present invention relates to an assembly-type ULD apparatus that covers and secures.

  Conventionally, there are two types of air cargo handling methods, the bulk loading method and the ULD method. Currently, most aircraft that arrive and depart in Japan are transported by the ULD method. The ULD method includes a container type using a box-shaped container that can be fixed to a tightening device provided on the floor of a cargo compartment as a tool, and a pallet type using a plate-like pallet as a tool.

  The container type has problems such as high transportation costs due to restrictions on the size of the cargo to be loaded because the cargo entrance is relatively small, and air containers are subject to customs procedures as independent shipping containers. ing. Therefore, conventionally, when small cargoes are put together in the cargo compartment of an aircraft using the ULD method, the small cargos are stacked on the base pallet, enclosed with curing materials such as plywood and cardboard, and then used with adhesive tape. It is often based on a pallet type that covers and protects the entire cargo unit with an outer box assembled in a box shape. Even if air cargo is expensive valuable goods such as game machines and digital video equipment, these small cargoes are stored in the outer box. Covered and wrapped so that the whole is not crushed.

The plate B is detachably connected to a hooking ring 11 provided on the outer periphery of the pedestal plate B through a fixing belt 12 of a hook-and-loop fastener to form a rectangular cylinder C as shown in an enlarged view in FIG. The adjacent side boards 15 to 18 are fastened so as to be detachable.

  Next, in the assembly-type ULD apparatus R, as shown in FIG. 1 and FIG. In the illustrated example, the connecting plates 56 and 57 folded in two are opened and alternately arranged to face each other, and the connecting convex pieces 56b and 57b are arranged in the thickness direction of the side end portions of the cover plate portions 51 and 52. Engage with each other on the outside and assemble as a lid by constraining the forward / backward and left / right movements by fitting the irregularities. The exterior box A includes the side boards 15 to 18 and the top board that form the rectangular cylinder C by inserting the fixing belt 12 of the surface fastener into the through holes 59 formed in the side boards 15 and 18 and the top board 50. 50 and 55 are detachably fastened.

  Therefore, in the assembly-type ULD apparatus R, as the top boards 50 and 55 forming the lid of the outer box A, a curing material made of a hard plastic having a blade-proof property is used, and the connecting plates 56 and 57 are alternately arranged. The connecting convex pieces 56b and 57b are engaged with each other on the outer side in the plate thickness direction of the side end portions of the lid plate portions 51 and 52, and the movement of the front, rear, left and right is constrained by the fitting of the irregularities. As a result of assembling the lid, in combination with the side boards 15 to 18 of the curing material having the blade-proof property that restrains the vertical and horizontal movements by fitting the irregularities, the curing material can be cut with a blade or corrugated cardboard etc. It is possible to prevent theft accidents caused by tricks such as shifting the curing board and removing a carton BOX containing expensive valuables such as game machines and digital video equipment.

  Thus, in the assembly-type ULD apparatus R, the exterior box A is assembled on the pedestal plate B by using the side boards 15 to 18 and the top board 50/55 of the curing material made of hard plastic having blade-proof properties, and the cargo unit. While covering the U, the fixing belt 12 of the hook-and-loop fastener is inserted into the through holes 59 opened in these boards, and the exterior box A is assembled detachably by the belt tightening method. Therefore, it can be appropriately decomposed and reused relatively easily.

  Further, in the assembly-type ULD apparatus R, the outer box A is assembled on the base plate B using the side boards 15 to 18 and the top boards 50 and 55, which are made of a hard plastic material having a blade-proof property, and the cargo. The entire unit U is covered and protected by fitting the unevenness of the board to constrain the movement in the up / down / left / right / front / back direction, and then covered with a vinyl sheet, and then wrapped so as not to crush the whole. Finally, as shown in FIG. 12, the net N is hung and cured. The hooks for hooking provided on the net N used for net tightening are hooked on hooking grooves that are cut along the outer edge of the base plate B, and the nets are tightened evenly.

  By the way, in the illustrated embodiment described above, the pallet P has a configuration in which the outer box A is directly mounted on the base plate B and secured, but the assembly-type ULD apparatus of the present invention is as follows. The pallet P can be configured to have a vibration isolating stand 75 with a vibration isolating function on the base plate B.

  In another example shown in the drawing, the pallet P has a plurality of vibration isolating means V as legs between a rectangular frame-shaped lower platform 76 placed on the base plate B and a rectangular frame-shaped upper platform 77 on which the cargo unit U is mounted. The anti-vibration stand 75 is provided with an anti-vibration stand 75 that supports the upper stand 77 elastically by connecting both the stands 76 and 77 up and down with the anti-vibration means V. The anti-vibration means V is a non-linear compression coil having non-linear spring characteristics. A spring 78 is provided, and the spring constant of the compression coil spring 78 is set so that the natural frequency is constant even when the mounted weight of the cargo unit U is displaced within a predetermined weight range.

  Therefore, in the assembling type ULD apparatus of the other example shown in the figure, the net N is hung around the cargo unit U together with the anti-vibration mount 75, and the net is firmly tightened (clamped). The non-linear compression coil spring 78 has a non-linear spring characteristic that can obtain a constant natural frequency regardless of the load of the cargo unit U in the weight range. However, the effective number of turns decreases according to the size of the tightening load, and it is bent by the net tightening by using the spring by bending at the coil part of the low weight belt with a large pitch between coil wires and a smaller spring constant. The tightening load can be buffered. As a result, according to the present invention, since the tightening force of the net tightening does not reach the anti-vibration gantry 75 and the spring property is not lost, the anti-vibration gantry 75 together with the dedicated load for securing cargo There is no need to cover the box and protect the net tightening force from reaching the anti-vibration means V, and the anti-vibration mount 75 and the cargo unit U can be directly connected to the cargo unit U and secured to the base plate B. As a result, a large amount of lashing boxes required every time the net is tightened is eliminated, and the transportation cost can be significantly reduced.
