Description

  The present invention relates to a prefabricated container that is used for conveying a desired article, and more particularly to a prefabricated container that is particularly effective when applied to a large container used in an aircraft.

  In a container that stores and transports and stores desired items, a side plate (side wall panel) is erected on the pallet to form a storage space when in use, and the side plate can be folded onto the pallet when not in use. Containers are known (see, for example, Patent Document 1 and Patent Document 2). The assembly-type container can reduce the volume of the container at the time of forwarding and storage, and is very effective in a container that is repeatedly used.

  In recent years, logistics by aircraft has been rapidly expanding, but an aircraft container used when an article is conveyed by an aircraft is larger than a container used for conveyance by a truck or the like. The size of a container used in a truck or the like is about 1 m on a side, for example, 970 × 1130 × 980 (mm), but the plane size of an aircraft pallet is, for example, 1500 × 2200 × 1600. It is a very large size (mm).

  In such a large prefabricated container, the size of the side plate in the longitudinal direction is 2200 × 1600 (mm). Therefore, if this is constituted by one side plate (plate-like member), it is difficult to handle, and for example, it is divided into two in the longitudinal direction.

  Conventionally, the two divided side plates are connected by a coupling mechanism as shown in FIG. In the example illustrated in FIG. 17, one split side plate 950 is provided with a contact plate 962 across the entire longitudinal direction outside the right frame member 955, and the other split side plate 970 has two upper and intermediate portions. In the vicinity of the left frame member 974 at a location, a round drop stopper 982 having a pin protruding in the direction of one divided side plate 950 is provided. In addition, a restriction pin 983 is formed in the vicinity of the round drop locking tool 982 in the middle part of the other divided side plate 970, and is located at a position corresponding to the restriction pin 983 of the contact plate 962 of the one divided side plate 950. The restriction pin engaging hole 963 is formed.

Then, as shown in FIG. 17, the regulation pin 983 formed on the left frame member 974 of the other divided side plate 970 is formed on the contact plate 962 attached to the outside of the right frame member 955 of the one divided side plate 950. The restriction pin engagement hole 963 is inserted, and in this state, the pins of the round drop engagement tool 982 provided at the upper left portion and the left intermediate portion of the other divided side plate 970 are in a protruded state.
As a result, the contact plate 962 installed on one of the divided side plates 950 is sandwiched between the left frame member 974 of the other divided side plate 970 and the pin of the round drop latch 982. The plate surface and the plate surface of the other divided side plate 970 are maintained in the same plane.

Also, the divided side plate divided into two is such that the lower frame material and the lower part of the connecting portion are locked to pins or grooves formed on the pallet so that the lower edge of the side plate does not bulge outward. It is configured.
Furthermore, when the upper lid is attached to the assembly type container, the upper edge of the two divided side plates is restrained by the upper lid, and the position thereof is regulated. It is configured not to swell.

  However, in such a conventional assembly-type container, that is, an assembly-type container in which the side plate constituting one side surface of the assembly-type container is divided, when the side plate is pressed from the outside, the connecting portion of the division side plate In this case, the inner part may be bent inward and may be deformed into a “V” shape. If the side plate is deformed in such a manner, there is a possibility that it may be adversely affected, such as the internal contained product being pressed or deformed.

  On the other hand, in a situation where the upper lid is not attached, the connecting portion of the divided side plate may be folded outwardly. If so deformed, the product cannot be properly accommodated, and the working efficiency is deteriorated. Further, as a result, the side plate (fixed side plate) in the short direction tilts inward, and as a result, the contained product may be pressed or deformed.

An embodiment of the present invention will be described with reference to FIGS.
In the present embodiment, the present invention will be described by exemplifying a prefabricated container for an aircraft (hereinafter referred to as an aircraft container or simply a container) that is used when an article is conveyed by an aircraft or the like.

FIG. 1 is an exploded perspective view showing a configuration of an aircraft container 1 according to an embodiment of the present invention.
As shown in FIG. 1, the aircraft container 1 includes a pallet 100, a lower metal frame 200, a bottom plate 300, a side plate 400, and an upper lid 500 as main components.

  The pallet 100 is a transport table for the container 1. A lift insertion space 110 into which a forklift claw is inserted is formed on the side surface of the pallet 100. The pallet 100 of the present embodiment is a skit type pallet configured by connecting prismatic members made of aluminum, “L” -shaped members, or plate-shaped members by welding or the like. The metal constituting the pallet 100 may be a metal other than aluminum such as iron or stainless steel. Alternatively, the pallet 100 may be integrally formed of resin or the like.

  The pallet 100 of this embodiment is a large sized pallet having a planar shape with a longitudinal length of 2200 (mm) and a lateral length of 1500 (mm). The height of the pallet 1 is 130 (mm).

  Further, at both side ends in the longitudinal direction of the pallet 100, as will be described later with reference to FIG. 12, the insertion side plate 440 of the side plate 400 (first divided insertion side plate 450, second divided insertion side plate 470). A chain housing box 120 is formed in which the coupling chain 490 installed in the housing is housed. The chain storage box 120 is formed by closing both side surfaces and the lower surface in the width direction between adjacent members of an aluminum rod-shaped member that constitutes the foot portion of the pallet 100 with a metal or resin plate member. Position where the connecting chain 490 on the lower side of the insertion side plate 440 hangs down when the insertion side plate 440 of the pallet 100 is erected on the edge of the upper surface of the pallet 100 (the connection chain 490 is fixedly installed on the insertion side plate 440 The opening 121 is formed at a position corresponding to the position), and the connecting chain 490 is dropped into and accommodated in the chain accommodation box 120 through the opening 121.

  The lower metal frame 200 is a support member that is installed along the short peripheral edge of the upper surface of the pallet 100, defines the position of the side plate 400, and assembles or folds them. The lower metal frame 200 includes a corner metal fitting 240 installed at each corner on the pallet 100 and a short direction frame portion 260 disposed so as to connect the short direction of the corner metal fitting 240. The corner metal fitting 240 and the short-side frame portion 260 have a welded integrated structure and are screwed or fixed to the pallet 100 with screws.

  As shown in FIG. 5, a hole (fixed side plate installation hole) 241 in which the fixed side plate 410 is installed is formed on a surface of the corner metal fitting 240 parallel to the longitudinal direction of the pallet 100. The fixed side plate installation hole 241 includes a horizontal hole portion 242 formed in the vicinity of the lower side of the corner metal fitting 240 in parallel with the upper surface of the pallet 100, and an upward direction (high) from the inner end of the horizontal hole portion 242 to the upper surface of the pallet 100. And a vertical hole portion 243 extending to the vicinity of the upper side of the corner metal fitting 240. That is, the fixed side plate installation hole 241 is a notch (L-shaped notch) formed in an “L” shape.

  A pin (rotating pin) 420 protruding outward in parallel to the plate surface of the fixed side plate 410 is installed at the lower part of both side end surfaces of the fixed side plate 410 to be described later. A pin 420 is slidably inserted along the horizontal hole portion 242 and the vertical hole portion 243. That is, both sides of one fixed side plate 410 are inserted into the fixed side plate installation holes 241 on the opposing surface (the surface along the longitudinal direction of the pallet 100) of the corner metal fitting 240 arranged to face the short direction of the pallet 100. The rotation pin 420 at the lower end face is inserted. As a result, the fixed side plate 410 cannot be detached from the corner metal fitting 240 in a state where the lower portion thereof is guided along the horizontal hole portion 242 and the vertical hole portion 243, in other words, also on the lower metal frame 200 and the pallet 100. It is held inseparable.

  Then, when the rotation pin 420 is moved to the end of the horizontal hole portion 242 of the fixed side plate installation hole 241 with the fixed side plate 410 standing vertically, the lower portion of the outer surface of the fixed side plate 410 is short. The inner side of the directional frame 260 is in close contact, the bottom of the outer surface is in close contact with the upper surface of the pallet 100, and cannot move directly in the upward direction, and the fixed side plate 410 is arranged when the container 1 is in the assembled state.

  In addition, when the pin 420 of the fixed side plate 410 is moved to the innermost position of the horizontal hole portion 242 of the fixed side plate installation hole 241 or the vertical hole portion 243, the fixed side plate 410 is in a state in which it can move upward and rotates. The pin 420 can be rotated about the pin 420 and can be folded on the pallet 100. The position (height) of the fixed side plate 410 in the folded state (in which the plate surface of the fixed side plate 410 is substantially parallel to the upper surface of the pallet 100) is arbitrary within the range of the vertical hole portion 243 of the fixed side plate installation hole 241. Position.

  The fixed side plate installation hole 241 of the corner metal fitting 240 is a hole for moving and arranging the fixed side plate 410 in this way. In other words, the arrangement, dimensions, and the like of the rotation pin 420 and the fixed side plate installation hole 241 are determined so that the fixed side plate 410 can be moved and arranged in this way. Thus, the fixed side plate 410 is integrated with the pallet 100 so as to be erected (assembled) and foldable.

  The height of the corner metal fitting 240 is four side plates 400, that is, two fixed side plates 410 and two insertion side plates 440 (integrated first divided insertion side plate 450 and second divided insertion side plate. When 470) is folded on the pallet 100, it is set to a height that can accommodate them. Thereby, in the state in which the aircraft container 1 is folded (when the aircraft container 1 is forwarded, stored, etc.), the upper lid 500 is mounted so as to directly cover the upper edge of the corner metal fitting 240 of the lower metal frame 200, The upper portions of the four side plates 400 stacked (folded) on the pallet 100 are closed.

  As shown in FIG. 1, the bottom plate 300 is a plate member that defines the lower surface of the storage space of the container 1, and its position is defined by the lower metal frame 200 and is placed on the upper surface of the pallet 100. The material of the floor board 300 is a plastic cardboard board in this embodiment, but may be a synthetic resin board (including a foamed synthetic resin board), a thin metal board, a plywood board, a fiber board, or the like.

The side plate 400 is a plate member that stands up along the peripheral edge of the upper surface of the pallet 100 and defines the side surface of the storage space of the container 1.
The side plate 400 has a pair of fixed side plates 410 and a pair of insertion side plates 440. In addition, each of the insertion side plates 440 is divided into two along the direction in which the fixed side plate 410 is opposed to each other, and is referred to as a first divided insertion side plate 450 and a second divided insertion side plate 470. The first divided insertion side plate 450 and the second divided insertion side plate 470 are integrated when standing on the pallet 100 to form a single insertion side plate 440 in the longitudinal direction of the storage space of the container 1. Configure.

  The pair of fixed side plates 410 are arranged on one side of the rectangular pallet 100 where the short direction frame portion 260 is installed so as to face each other along the short direction frame portion 260. Further, the pair of insertion side plates 440 are opposed to each other along the longitudinal direction of the pallet 100 on the other opposite side of the pallet 100 which is the longitudinal direction of the pallet 100, and both sides of the fixed side plate 410. Arranged to connect edges.

  As shown in FIG. 2A, the fixed side plate 410 includes an upper frame member (upper reinforcing frame member) 412 as an outer peripheral reinforcing frame member and a lower frame member (lower reinforcing frame member) around a panel member (surface member) 411. 413, a left frame member (left reinforcing frame member) 414, and a right frame member (right reinforcing frame member) 415.

  As shown in FIG. 2 (B), insertion side plate insertion grooves 417 each having an open portion so as to face the inside of the aircraft container 1 are formed on the left and right edges of the fixed side plate 410. The insertion side plate 440 adjacent to the fixed side plate 410 is inserted into the insertion side plate insertion groove 417 when the aircraft container 1 is assembled by standing the side plate 400 on the pallet 100.

  The panel material 411 is a rectangular surface member having substantially the same size as the fixed side plate 410, and is a plastic corrugated board having a thickness of 10 (mm) in the aircraft container 1 of the present embodiment.

  As shown in FIG. 2B and FIG. 3A, the reinforcing frame members 412 to 415 are each a long member (reinforcing member) having a U-shaped cross section, in other words, a groove portion 416 ( The inner groove portions of the reinforcing frame members 412 to 415 are all long members formed by reference numeral 416. In the aircraft container 1 of the present embodiment, an aluminum extruded mold member having a thickness of 2 (mm) is used. is there. The reinforcing frame members 412 to 415 are arranged around the panel material 411 by fitting the groove portion 416 to the edge of the panel material 411, thereby constituting the outer frame of the fixed side plate 410 and the panel material as the side plate. Reinforce the strength of 411.

  The reinforcing frame members 412 to 415 are connected to and fixed to the adjacent reinforcing frame members 412 to 415 at the corners of the fixed side plate 410 (panel material 411) in order, and thereby the outer peripheral reinforcing frame integrated. It is composed of materials.

A method of connecting and fixing the reinforcing frame members 412 to 415 will be specifically described with reference to FIGS. 3 and 4 as an example of a connecting portion between the upper reinforcing frame member 412 and the left reinforcing frame member 414.
As shown in FIG. 3A, in the connection portion between the upper reinforcing frame member 412 and the left reinforcing frame member 414, the end surface of the longitudinal end of the upper reinforcing frame member 412 is the longitudinal direction of the left reinforcing frame member 414. The upper reinforcing frame member 412 and the left reinforcing frame member 414 are arranged so as to be in contact with the inner side of the end side in the longitudinal direction (the side where the groove 416 is formed). The upper reinforcing frame member 412 and the left reinforcing frame member 414 are arranged such that their longitudinal directions are perpendicular to each other and each groove 416 is directed inward.

  In this state, the connection fitting 435 is disposed inside each groove 416 of the upper reinforcing frame member 412 and the left reinforcing frame member 414 so as to extend over both the upper reinforcing frame member 412 and the left reinforcing frame member 414. The reinforcing frame member 412 and the left reinforcing frame member 414 are each fixed to the connection fitting 435 by rivets. As a result, the upper reinforcing frame member 412 and the groove 416 are connected and fixed orthogonally via the connection fitting 435.

  As shown in FIG. 3B, the connection fitting 435 is a metal plate member having an L-shaped cross section having a first surface 436 and a second surface 437, and the aircraft container 1 of the present embodiment. Is a stainless steel member having a thickness of 0.6 to 0.8 (mm).

  When the connection fitting 435 is disposed in the groove portion 416 of the upper reinforcement frame member 412 and the left reinforcement frame member 414, the first surface 436 of the connection fitting 435 extends along the side surface of the groove portion 416, in other words, the groove portion 416. The second surface 437 of the connection fitting 435 is disposed along the bottom surface of the groove portion 416, in other words, is disposed so as to contact the bottom surface of the groove portion 416. Therefore, the width W1 of the first surface 436 of the connection fitting 435 is substantially equal to the depth of the groove 416 of the upper reinforcing frame member 412, and the width W2 of the second surface 437 of the connection fitting 435 is The reinforcing frame member 412 is formed to have a width equal to or less than the width of the bottom surface of the groove portion 416 of the reinforcing frame member 412.

  The upper reinforcing frame member 412 and the left reinforcing frame member 414 are each fixed to the connection fitting 435 by two rivets, and thus by a total of four rivets.

  As shown in FIG. 4, when actually manufacturing the fixed side plate 410, first, the connection fitting 435 is disposed at a predetermined position of the corner of the panel material 411 (step 1), and the upper reinforcing frame is against this. The material 412 is fitted into a predetermined position (step 2), and the panel material 411 and the upper reinforcing frame material 412 fitted with the connection fitting 435 interposed therebetween are finally fitted into the left reinforcing frame material 414 ( In step 3), the upper reinforcing frame member 412 and the left reinforcing frame member 414 are connected and fixed by driving rivets into the connection fitting 435 from the side surfaces of the upper reinforcing frame member 412 and the left reinforcing frame member 414 (step 4). The

  Thus, in the aircraft container 1 according to the present embodiment, the upper reinforcing frame member 412 and the left reinforcing frame member 414 of the fixed side plate 410 are simply in contact with each other without fitting, engaging or overlapping the end portions. Are arranged in contact with each other and are connected and fixed via a connection fitting 435.

In the fixed side plate 410, each end of the adjacent reinforcing frame members 412 to 415 is connected to the upper reinforcing frame member 412 and the left reinforcing frame member 414 described above with reference to FIGS. The connection is fixed in the same form as the fixed form.
That is, as shown in FIG. 2A, adjacent left reinforcing frame member 414 and lower reinforcing frame member 413, lower reinforcing frame member 413 and right reinforcing frame member 415, and right reinforcing frame member 415 and upper reinforcing frame member. 412 indicates that the end surface of the longitudinal end of the upper reinforcing frame member 412 or the lower reinforcing frame member 413 is the inner side (groove portion) of the longitudinal end of the left reinforcing frame member 414 or the right reinforcing frame member 415. The reinforcing frame members 412 to 415 are fixed to the connection fittings 435 disposed in the groove portions 416 of the reinforcing frame members 412 to 415 by rivets. As a result, they are sequentially connected and fixed in an orthogonal state.

  Note that the panel material 411 is not limited to a plastic corrugated board, and other material face materials such as a synthetic resin plate (including a foamed synthetic resin plate), a thin metal plate, a plywood, and a fiber plate may be used.

  As shown in FIGS. 1, 5, and 7, the left side reinforcement frame member 414 and the right side reinforcement frame member 415 of the fixed side plate 410 are pivotally inserted into the fixed side plate installation hole 241 of the corner metal fitting 240 as shown in FIGS. The pins 420 are installed so as to protrude outward in parallel with the plate surface of the fixed side plate 410. For example, as shown in FIG. 7, the rotating pin 420 is arranged on the outer side of the right reinforcing frame member 415, and the hexagon socket head bolt 420 serving as the rotating pin 420 itself is inserted into the right reinforcing frame member 415 on the insertion side plate. A nut 421 with a loosening prevention disposed inside the insertion groove 417 is engaged. In such a configuration, simply by turning the hexagon socket head bolt (rotating pin) 420, the nut 421 with a loosening prevention rotates together, and the hexagon socket head bolt (rotating pin) 420 and the nut 421 with a loosening prevention are provided. Can not be removed. Therefore, the rotation pin 420 cannot be removed from the fixed side plate 410, and the fixed side plate 410 cannot be removed from the lower metal frame 200 (pallet 100).

  As described above with reference to FIG. 5, the fixed side plate 410 having such a configuration has the rotation pin 420 movably fitted in the fixed side plate installation hole 241 of the corner metal fitting 240, so that the lower metal frame 200 ( The pallet 100) cannot be detached. Then, with the fixed side plate 410 standing upright, the rotation pin 420 is moved to the end of the horizontal hole portion 242 of the fixed side plate installation hole 241, so that the lower portion of the fixed side plate 410 is in the short direction. The frame 260 is in close contact with the inside, the bottom of the outer surface is in close contact with the top surface of the pallet 100, and cannot be moved directly upward, so that the fixed side plate 410 is arranged in the assembled state. Further, when the pin 420 of the fixed side plate 410 is moved to the innermost position of the horizontal hole portion 242 of the fixed side plate installation hole 241 or the vertical hole portion 243, the fixed side plate 410 becomes movable in the upward direction and rotates. It will be in the state which can be rotated centering | focusing on the moving pin 420, and will be in the state which can be folded on the pallet 100. FIG.

  Further, as shown in FIG. 8 (enlarged view of the portion A in FIG. 1), the upper ends of the side surfaces of the left reinforcing frame member 414 and the right reinforcing frame member 415 (the right reinforcing frame member 415 in FIG. 8) of the fixed side plate 410. The insertion side plate 440 (the first divided insertion side plate 450 and the second divided insertion side plate 470) is inserted between the fixed side plates 410 and installed in the insertion side plate insertion groove 417 portion. In this case, the vertical reinforcing frame member 454 of the first divided insertion side plate 450 and the vertical reinforcing frame member 475 of the second divided insertion side plate 470 (in FIG. 8, the vertical reinforcing frame member of the first divided insertion side plate 450 are used. 454) is formed with an “L” -shaped engagement notch 425 that engages with an engagement nut 461 (481) installed at the upper end of the outer surface.

A structure for connecting (connecting) and integrating the first divided insertion side plate 450 and the second divided insertion side plate 470 will be described below with reference to FIGS.

First, a contact plate 462 is attached to the first split insertion side plate 450 over the entire longitudinal direction outside the vertical reinforcing frame member 455. The contact plate 462 is in the inner / outer direction of the first divided insertion side plate 450 and the second divided insertion side plate 470 at the connection point between the first divided insertion side plate 450 and the second divided insertion side plate 470. And the gap between the connecting portions of the first divided insertion side plate 450 and the second divided insertion side plate 470 is sealed.
The contact plate 462 is installed on the vertical reinforcing frame member 455 of the first split insertion side plate 450 by welding or the like.

  On the upper left side of the upper reinforcing frame member 472 of the second divided insertion side plate 470, it is movable along the longitudinal direction of the upper reinforcing frame member 472, that is, along the upper edge of the second divided insertion side plate 470. There is embedded a spindle shaft 484 that can protrude from the upper left end of the second divided insertion side plate 470 toward the first divided insertion side plate 450. A spindle pin 485 is provided on the spindle shaft 484 so that an operator can hold it and move the spindle shaft 484.

In addition, on the upper right side of the upper reinforcing frame member 452 of the first divided insertion side plate 450, along the longitudinal direction of the upper reinforcing frame member 452, that is, along the upper edge of the first divided insertion side plate 450, A hollow portion (spindle shaft accommodating portion) 466 that can accommodate the spindle shaft 484 protruding from the upper left end portion of the second divided insertion side plate 470 is formed.
In the first divided insertion side plate 450 and the second divided insertion side plate 470, the spindle shaft 484 protruding from the second divided insertion side plate 470 is inserted into the cavity 466 of the second divided insertion side plate 470. By doing so, the upper edge is connected.

  The spindle shaft 484 is inserted and installed in a cavity portion 486 formed on the upper left side of the second divided insertion side plate 470. In the second divided insertion side plate 470, a cavity portion 486 is provided between the bottom portion of the groove portion of the upper reinforcing frame member 472 and the upper surfaces of the panel member 471 and the connection fitting 435. In order to form such a cavity portion 486, a cutout portion is formed in the upper left portion of the panel material 471 in the second divided insertion side plate 470. This notch is formed over a range in which the spindle shaft 484 is accommodated and a range in which it moves.

  Further, the connection fitting 435 is attached along the notch to the panel material 471 in which the notch is formed. As a result, in the upper left part of the second divided insertion side plate 470, as shown in FIG. 9, the second surface 437 of the connection fitting 435 is not in contact with the bottom surface of the groove portion of the upper reinforcing frame member 472. In this case, the cavity 486 in which the spindle shaft 484 is accommodated is formed between the second surface 437 of the connection fitting 435 and the bottom surface of the groove portion of the upper reinforcing frame member 472.

  A spindle shaft housing portion 466 into which the spindle shaft 484 is inserted, which is formed along the upper edge of the first divided insertion side plate 450, is also formed in the same manner as the cavity portion 486 of the second divided insertion side plate 470. . That is, in the first split insertion side plate 450, the spindle shaft accommodating portion 466 is provided between the bottom portion of the groove portion of the upper reinforcing frame member 452 and the upper surfaces of the panel member 451 and the connection fitting 435. In order to form such a spindle shaft housing portion 466, a cutout portion is formed in the upper right portion of the panel material 451 over the range in which the spindle shaft 484 is inserted and the range in which it moves.

  The connection fitting 435 is attached along the notch to the panel member 451 in which the notch is formed. Accordingly, in the upper left part of the first divided insertion side plate 450, the connection fitting 435 has a state in which the second surface 437 does not contact the bottom surface of the groove portion of the upper reinforcing frame member 452, that is, the second surface 437 of the connection fitting 435. And a spindle shaft accommodating portion 466 that accommodates the spindle shaft 484 between the upper reinforcing frame member 452 and the bottom surface of the groove portion of the upper reinforcing frame member 452.

  Note that these connection fittings 435, that is, the connection fitting 435 connecting the upper reinforcement frame member 472 and the vertical reinforcement frame member 474 of the second divided insertion side plate 470, and the upper portion of the first division insertion side plate 450 are provided. Regarding the connection fitting 435 that connects the reinforcement frame member 452 and the vertical reinforcement frame member 455, in the aircraft container 1 of the present embodiment, the connection fitting 435 extends along the panel members 471 and 451 as described above. Although the second surface 437 is mounted in a state where it does not contact the bottom surfaces of the groove portions of the upper reinforcing frame members 472 and 452, the connection fitting 435 may be mounted along the groove portions of the upper reinforcing frame members 472 and 452.

  That is, you may mount | wear with the form which the 2nd surface 437 of the connection metal fitting 435 touches the bottom face of the groove part of the upper reinforcement frame material 472,452. In that case, a gap is generated between the back surface of the second surface 437 of the connection fitting 435 and the top surfaces of the panel members 471 and 451 (the top surfaces of the notches), and this clearance is attached to the spindle shaft 484. The hollow portion 486 or the spindle shaft housing portion 466 into which the spindle shaft 484 is inserted. The 2nd division | segmentation insertion side plate 470 and the 1st division | segmentation insertion side plate 450 are good also as such a form.

  An opening 487 for projecting the spindle shaft 484 to the outside is formed at the upper left end surface of the second divided insertion side plate 470 and the end surface of the cavity 486. Further, an opening 467 for inserting the spindle shaft 484 is formed at the upper right end surface of the first divided insertion side plate 450 and at the position which becomes the end surface of the spindle shaft housing portion 466. When the second divided insertion side plate 470 and the first divided insertion side plate 450 are connected and integrated as one insertion side plate 440, the opening 487 and the opening 467 are in contact at the same position. The hollow portion 486 of the second divided insertion side plate 470 and the spindle shaft accommodating portion 466 of the first divided insertion side plate 450 are linear along the upper edge of the insertion side plate 440. Connected to

  A clearance groove 476 in which the knob pin 485 of the spindle shaft 484 can move is formed in the upper part of the upper reinforcing frame member 472 of the second divided insertion side plate 470. The clearance groove 476 includes a shaft moving horizontal groove 477, a retracted state maintaining vertical groove 478, and a protruding state maintaining vertical groove 479.

  The shaft moving horizontal groove 477 is a groove formed on the upper surface of the upper reinforcing frame member 472, and moves the knob pin 485 of the spindle shaft 484 along this, that is, the second divided insertion side plate 470. This is a groove that can move the spindle shaft 484 in the horizontal direction (longitudinal direction of the upper reinforcing frame member 472) by sliding the knob pin 485 in the horizontal direction.

  The retracted state maintaining vertical groove 478 is a groove formed vertically from the inner end of the shaft moving horizontal groove 477 along the outer side surface of the upper reinforcing frame member 472. The protruding state maintaining vertical groove 479 is a shaft. It is a groove formed vertically from the outer end of the moving horizontal groove 477 along the outer side surface of the upper reinforcing frame member 472. The retracted state maintaining vertical groove 478 and the protruding state maintaining vertical groove 479 both cause the knob pin 485 of the spindle shaft 484 to tilt and move along the side surface direction of the second divided insertion side plate 470 (substantially). This is a groove in which the horizontal movement of the knob pin 485, that is, the spindle shaft 484 is restricted (cannot be moved in the horizontal direction).

  The retracted state maintaining vertical groove 478 is the inner end of the shaft moving horizontal groove 477, and when the knob pin 485 is in this position, all of the spindle shaft 484 is inside the second split insertion side plate 470. It is formed at a position where it is housed in the housing. Therefore, when the knob pin 485 is tilted and moved to the retracted state maintaining vertical groove 478, the spindle shaft 484 is maintained in the retracted and accommodated state in the second divided insertion side plate 470.

  The protruding state maintaining vertical groove 479 is the outer end of the shaft moving horizontal groove 477, and when the knob pin 485 is in this position, approximately half of the spindle shaft 484 is formed on the second split insertion side plate 470. It is formed at a position where it protrudes from the upper left end along the upper edge of the second divided insertion side plate 470 toward the first divided insertion side plate 450. Therefore, when the knob pin 485 is tilted and moved to the protruding state maintaining vertical groove 479, half of the spindle shaft 484 is inserted into the first split insertion from the left end of the second split insertion side plate 470. It will be maintained in a state protruding in the direction of the side plate 450.

  In the first divided insertion side plate 450 and the second divided insertion side plate 470 having such a configuration and the spindle shaft 484, the knob pin 485 is maintained in the retracted state maintaining vertical groove 478, and the spindle shaft 484 is In the state accommodated in the 2nd division | segmentation insertion side plate 470, it is a state which is not connected in the upper edge. The spindle shaft 484 is in such a state when the insertion side plate 440 is opened in order to accommodate or take out articles.

  On the other hand, when integrating the 1st division | segmentation insertion side plate 450 and the 2nd division | segmentation insertion side plate 470, the side end surface of the 1st division | segmentation insertion side plate 450 and the 2nd division | segmentation insertion side plate 470 is used. The contact state is set, and the knob pin 485 is moved from the retracted state maintaining vertical groove 478 to the position of the protruding state maintaining vertical groove 479 through the shaft moving horizontal groove 477. By this operation, a substantially half portion of the spindle shaft 484 protrudes from the opening 487 of the second divided insertion side plate 470 and is inserted into the spindle shaft accommodating portion 466 of the first divided insertion side plate 450. That is, half of the spindle shaft 484 is arranged along the upper edge of the second divided insertion side plate 470 and half is arranged along the upper edge of the first divided insertion side plate 450. . As a result, the first divided insertion side plate 450 and the second divided insertion side plate 470 are connected by the spindle shaft 484.

  The first divided insertion side plate 450 and the second divided insertion side plate 470 are connected by the spindle shaft 484 at the upper edge of the first divided insertion side plate 450, so that in the insertion side plate 440, It is possible to more reliably prevent a situation where the second split insertion side plate 470 is connected to the second split insertion side plate 470 and is in a folded state or a bulging or recessed state.

  In addition, the second split insertion side plate 470 includes a first split difference at two locations, an upper portion and an intermediate portion of the outer side surface on the vertical reinforcing frame member 474 side (the connection side with the first split insertion side plate 450). A round drop stopper 482 in which a pin protrudes in the direction of the insertion side plate 450 is provided (the upper round drop stopper 482 is shown in FIGS. 9 and 10). In addition, a restriction pin 483 is formed on the vertical reinforcing frame member 474 in the vicinity of each round drop locking tool 482 toward the outside. Further, a restriction pin engagement hole 463 is formed at a position corresponding to the restriction pin 483 of the contact plate 462 of the first divided insertion side plate 450.

Further, the retaining ring 492 at the other end is arranged in the chain housing box 120 of the pallet 100 described above. The opening 121 of the chain storage box 120 is formed in such a size that the connecting chain body can pass but the retaining ring 492 cannot pass. In other words, the retaining ring 492 having such a size is attached to the other end of the connecting chain 490. As a result, as shown in FIG. 12A, the retaining ring 492 cannot be removed from the chain housing box 120, and the other end of the connecting chain 490 cannot be detached from the pallet 100. Connected.
As a result, even when the divided insertion side plates 450 and 470 are extracted from the fixed side plate 410, the divided insertion side plates 450 and 470 are maintained in a state of being connected to the pallet 100 by the connecting chains 490.

  The connecting chain 490 having one end portion installed on the lower reinforcing frame members 453 and 473 of the divided insertion side plates 450 and 470 protrudes to the outside from the lower surface of the divided insertion side plates 450 and 470. It is installed on the split insertion side plates 450 and 470 so as to hang from the lower surface of the side plates 450 and 470. Further, as described above, the chain storage box 120 and the opening 121 of the pallet 100 are positions corresponding to the positions where the connection chains 490 are installed when the split insertion side plates 450 and 470 are assembled (positions depending on the position). Is formed.

  Accordingly, when the split insertion side plates 450 and 470 are inserted into the fixed side plate 410 and the aircraft container 1 is assembled, the connecting chain 490 is dropped into the chain storage box 120 by the weight of the retaining ring 492. Will go. That is, by connecting the divided insertion side plates 450 and 470 into the insertion side plate insertion groove 417 of the fixed side plate 410 according to a normal procedure, the connecting chains 490 are substantially automatically accommodated in the pallet 100. It will be housed inside the box 120. Therefore, the installation of the connecting chain 490 does not add a new procedure or the like to the assembly work of the aircraft container 1, and does not complicate the work.

  Further, in the state in which the insertion side plate 440 is assembled, the connecting chain 490 is completely accommodated in the chain accommodation box 120 as shown in FIG. 1 from the inside of the housing space 1). Accordingly, the connecting chain 490 does not interfere with the contents inside the aircraft container 1 or the articles around the aircraft container 1 to cause damage or the like.

  The length of the connecting chain 490 is such that the entire connecting chain 490 can be accommodated in the chain accommodating box 120 of the pallet 100, and when the aircraft container 1 is folded, the divided insertion side plates 450 and 470 are attached to the pallet 100. It is a length that can be placed on the top, and when carrying out the operation of storing articles in the aircraft container 1 by removing the divided insertion side plates 450 and 470, or when performing the operation of taking out articles from the aircraft container 1 Any length may be used as long as the divided insertion side plates 450 and 470 can be retracted. More specifically, each of the divided insertion side plates 450 and 470 is stood on the outside of the adjacent fixed side plate 410, or is laid on the floor near the aircraft container 1 or the like. When the situation is assumed, each of the connecting chains 490 ensures a length capable of realizing such a situation, while the insertion side plate 440 is raised when the insertion side plate 440 is inserted or removed. It is preferable that the length is a length that does not need to be lifted and that does not interfere with the work.

Further, the member constituting the connecting chain 490 can be a member such as a string made of any material in order to connect the pallet 100 and the insertion side plate 440. However, in order to effectively realize the effect that the connecting chain 490 is dropped into the chain storage box 120 by its own weight as described above, the connecting chain 490 has a certain weight. It is also preferable to use a member that is appropriately bent and accommodated in the chain accommodation box 120 without causing unnecessary stress in any direction. Therefore, it is very preferable and effective to use a metal chain.
For the same reason, the retaining ring 492 is also preferably made of a member having a certain weight, that is, a metal or the like.

  The upper lid 500 is a member that closes the upper opening of the accommodation space of the container 1 formed by the side plates 400 (the fixed side plates 410 and the insertion side plates 440) erected on the pallet 100.

  In order to make the upper lid 500 inseparable from the fixed side plate 410, the upper lid 500 slides along the upper side of one fixed side plate 410 and cannot be separated as will be described later.

  Thus, in the aircraft container 1 of this embodiment, since the upper edge of the divided side plate is connected by the spindle shaft 484, the integrity of the insertion side plate 440 can be improved. That is, even when the side plate is pushed from the outside, it is possible to prevent the split side plate from being folded inward or deformed into a “V” shape at the connecting portion of the divided side plate. Further, even in a situation where the upper lid is not attached, it is possible to prevent the connecting portion of the divided side plates from being folded outward.

  As a result, it is possible to prevent the contained product from being pressed or deformed due to the deformation of the side plate and to be adversely affected, and a desired article can be transported in a large amount appropriately efficiently and safely. In addition, the product can be appropriately accommodated, and the handling of the large side plate is facilitated, so that the work efficiency can be improved.

  Therefore, according to the present invention, the side plate forming one side is an assembled container formed by the divided side plates, and the side plates in the state in which the divided side plates are integrated are high in rigidity, and can be used when storing articles. It is possible to provide a prefabricated container that can prevent deformation such as folding, and can safely and properly accommodate and transport articles.

  Further, in the aircraft container 1 of the present embodiment, the outer peripheral reinforcing frame member is replaced with the adjacent reinforcing frame member in each of the fixed side plate 410, the first divided insertion side plate 450, and the second divided insertion side plate 470. The end portions are not fitted, engaged, or overlapped, but are simply placed in contact with each other and placed in contact with each other, and connected and fixed via a connection fitting 435.

Therefore, the structure is simple and high-precision grinding is not required, and for example, it is possible to prevent a step from being generated in the outer peripheral reinforcing frame member at the connecting portion of the reinforcing member. Moreover, since it is not necessary to grind a reinforcement member in the corner | angular part of an outer periphery reinforcement frame material and to make it thin, the intensity | strength of an outer periphery reinforcement frame material is securable. Further, since precise grinding is not required, the side plate manufacturing operation can be simplified and shortened, and the cost can be reduced.
As a result, it is possible to provide a prefabricated container having a simple structure, high accuracy, and low cost.

  Such an effect is particularly effective in a large container such as an aircraft container. Therefore, according to the invention of the present application, it is possible to provide an assembly type container capable of efficiently transporting articles by an aircraft or the like.

  Further, in the aircraft container 1 of the present invention, all members of the aircraft container 1 including the divided insertion side plates 450 and 470 and the upper lid 500 are connected to the pallet 100. Accordingly, when the aircraft container 1 is used, a part thereof, that is, a detachable member (part) such as an upper lid or a side plate is not lost, and a state where necessary members are always maintained can be maintained. it can. Moreover, it becomes easy to prevent the state where other container members are mixed.

In addition, while the respective members are connected as described above, the assembly, folding, or storage or removal of articles in the assembled state (in use) is subject to restrictions such as connecting members. It can be performed efficiently and conveniently.
Therefore, the aircraft container 1 is very useful as a container for transporting articles by an aircraft or the like, and further as a container for transporting articles outside the country where various checks such as inspection of members are performed. .

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention.

For example, any mechanism may be used as the mechanism for installing the upper lid 500 so as to be slidable.
Specifically, an elongated hole into which the upper lid sliding pin 430 can be inserted is formed in the longitudinal direction of the frame edge 514 of the upper lid 500, and the upper lid sliding pin 430 is inserted into this to slide the upper lid 500. You may do it. With such a configuration, it is not necessary to form the ridges 515 on the frame edge 514, and an opening (elongate hole) may be formed in the frame edge 514. In addition, it requires less members and is suitable.

Alternatively, the frame edge 514 of the upper lid 500 may be formed in a U-shaped cross section to form a groove on the inside, and the upper lid sliding pin 430 may be inserted into the groove so that the upper lid 500 can be slid. . Such a configuration is preferable because the strength of the frame portion 512 of the upper lid 500 or the frame portion edge portion 514 can be increased.
The present invention may be realized in such a form, for example.
