The second side plate 420 is erected along the second frame portion 220 by inserting the prevention pins 427 into the prevention pin insertion holes 227, and is further provided at four locations of the container 1 by a plate clamping mechanism 430 described later. The first side plate 410 and the second side plate 420 adjacent to each other at the upper corners are sequentially engaged with each other so that the four first side plates 410 and the second side plate 420 are separated from each other. In addition, the first frame portion 210 and the second frame portion 220, that is, the pallet 100, cannot be removed upward.

  Further, as shown in FIG. 1, the height of the first side plate 410 is shorter than the height of the second side plate 420, and the first side plate 410 and the second side plate 420 are erected along the lower frame 200. In this case, the lower edge of the first side plate 410 is disposed above the lower edge of the second side plate 420. For this purpose, a step 212 on which the first side plate 410 is placed is provided inside the first frame 210 as shown in FIG. That is, when the first side plate 410 is erected along the first frame portion 210, the first side plate 410 is placed on the stepped portion 212.

  The floor plate 300 is a plate member that defines the lower surface of the accommodation space of the assembly-type container 1 and is placed in a range surrounded by the lower frame 200 on the pallet 100. The material of the floor board 300 is not particularly limited, and a plastic corrugated board, a synthetic resin board (including a foamed synthetic resin board), a metal plate, a plywood board, a fiber board, or the like is used.

Each of the two first side plates 410 and second side plates 420 is erected on the peripheral edge of the upper surface of the pallet 100 and forms an internal storage section of the assembly-type container 1 that stores a desired article.
The pair of first side plates 410 are disposed so as to face each other on one side of the rectangular pallet 100, and the pair of second side plates 420 are also opposed to each other on the other side of the pallet 100. In addition, the both side ends of the first side plate 410 are arranged to be connected.

  The first side plate 410 and the second side plate 420 have a configuration in which frame members such as side end frame members and upper and lower frame members are mounted around the surface member. Although the material of the face member is not particularly limited, for example, a plastic corrugated board similar to the floor board 300, a synthetic resin board (including a foamed synthetic resin board), a metal board, a plywood board, a fiber board, or the like is used. The frame member is made of a metal such as steel.

  As shown in FIG. 2, the first side plate 410 has side plate position defining pins 415 that protrude in the direction of extending the lower edge on both sides of the lower edge. When attaching the first side plate 410 to the pallet 100, the side plate position defining pins 415 are dropped into the grooves 215 formed on both sides of the first frame portion 210. As a result, the first side plate 410 is held at a position in the horizontal direction of its lower edge along the first frame portion 210. As described above, the lower edge of the first side plate 410 is placed on the stepped portion 212 of the first frame portion 210, whereby the first side plate 410 has the lower edge and the side plate. The position defining pin 415 is rotated as a fulcrum, and is set up along the first frame portion 210 or folded (laid down) on the pallet 100.

  Engagement plates 413 for engaging with the second side plate 420 are formed on both the left and right side edge portions of the first side plate 410. The engagement plate 413 is a thin plate-like portion extending in the inner direction (in the direction of the second side plate 420) perpendicular to the plate surface from the peripheral portions on the left and right sides of the first side plate 410. The engagement plate 413 is formed by extending a part of the frame member of the first side plate 410 inward, or by using a metal fitting having an L-shaped cross section as a frame member on both sides of the first side plate 410. It is preferable to do this. When the first side plate 410 and the second side plate 420 are erected on the pallet 100, the second side plate 420 adjacent to the engagement plate 413 of the first side plate 410 is closely arranged, and the second side plate 420 The close contact state is maintained by the rotary side plate locking plate 431 provided in the side plate 420.

  An engagement pin fitting hole 414 into which the engagement pin 424 provided in the second side plate 420 is fitted is formed in the upper portion of the engagement plate 413 of the first side plate 410. As described above, in the state where the first side plate 410 and the second side plate 420 are erected so that the second side plate 420 is in close contact with the engagement plate 413 of the first side plate 410, the second side plate 420. The engaging pin 424 is fitted into the engaging pin fitting hole 414 of the first side plate 410.

  As shown in FIG. 3, the second side plate 420 has side plate position defining pins 425 projecting in the direction of extending the lower edge on both sides of the lower edge. The side plate position defining pins 425 are formed to have a length substantially the same as the thickness of the adjacent first side plate 410.

  In addition, at both ends of the lower frame of the second side plate 420, when the second side plate 420 is erected along the second frame portion 220, the removal prevention pin insertion hole 227 of the second frame portion 220 is formed. An insertion prevention pin 427 to be inserted is formed so as to protrude outward from the outer surface. The second side plate 420 is erected along the second frame portion 220 by inserting the prevention pins 427 into the removal prevention pin insertion holes 227 of the second frame portion 220. It is in a state where it cannot escape upward with respect to 220.

  A band 428 is attached to the outer surface of the second side plate 420 in order to raise the second side plate 420 tilted on the pallet and to stand on the pallet 100.

When the second side plate 420 is attached to the pallet 100, the lower edge portion of the second side plate 420 including the side plate position defining pins 425 is disposed along the second frame portion 220. At this time, the second side plate 420 is slightly tilted inward so that the drop prevention pins 427 provided on the lower frame portion of the second side plate 420 do not interfere with the second frame portion 220, or The second side plate 420 is laid to a level substantially parallel to the floor plate 300, and the lower edge portion of the second side plate 420 is disposed inside the second frame portion 220.
After that, the first side plate 410 is mounted after dropping the side plate position defining pin 415 into the groove 215 of the first frame part 210 as described above, or the first side plate 410 is mounted as such. Before, the second side plate 420 is erected vertically on the pallet 100 so as to follow the second frame portion 220 by causing a band 428 of the second side plate 420. As a result, the removal prevention pin 427 provided in the lower frame portion of the second side plate 420 is inserted into the removal prevention pin insertion hole 227 provided in the second frame portion 220, whereby the second side plate 420 is The second frame portion 220 is installed in a state that does not come out upward.

  Returning to FIG. 3, when the first side plate 410 and the second side plate 420 are erected on the pallet 100 at the left and right edges on the outer surface of the second side plate 420, Engagement pins 424 that are fitted into engagement pin fitting holes 414 formed in the engagement plate 413 are formed. The second side plate 420 is erected in close contact with the engagement plate 413 of the first side plate 410 by fitting the engagement pin 424 into the engagement pin fitting hole 414 of the first side plate 410. The first side plate 410 is maintained in a state where it does not move at least in the vertical direction.

  Further, the engagement plate 413 of the first side plate 410 is placed between the plate surface of the second side plate 420 and the engagement pins 424 on the left and right edges of the upper part of the outer surface of the second side plate 420. A plate clamping mechanism 430 having a rotary side plate locking plate 431 for clamping is installed.

  As shown in FIGS. 6A and 6B, the plate clamping mechanism 430 includes a rectangular thin plate member (rotary side plate locking plate) 431 at both ends of the upper frame of the second side plate 420. In this configuration, the plate mounting pins 432 are rotatably installed in the outer surface of the second side plate 420. The rotary side plate locking plate 431 is installed on the second side plate 420 by a plate mounting pin 432 in the vicinity of one end in the longitudinal direction thereof, and is installed rotatably around the plate mounting pin 432 as a rotation center. ing.

  Further, a U-shaped engagement groove 433 is formed in the other end 431a of the rotary side plate locking plate 431 so that the engagement pin 424 can be engaged therewith. The rotary side plate locking plate 431 has the other end 431a at the most edge side of the second side plate 420 at both the left and right upper ends of the second side plate 420 as shown in FIG. As described above, the engaging groove 433 is disposed so as to engage with the engaging pin 424 when the longitudinal direction is the horizontal direction. Therefore, in the plate clamping mechanism 430, if the rotary side plate locking plate 431 is rotated so as to drop in the direction of the engagement pin 424 from above (in the plate clamping mechanism 430 shown in FIG. 6B, the rotary side plate When the locking plate 431 is rotated counterclockwise), the engaging pin 424 engages with the engaging groove 433 of the rotary side plate locking plate 431, and the rotary side plate locking plate 431 is in its engaged state. Retained.

  Further, as shown in FIG. 6A, the rotary side plate locking plate 431 is between the outer surface of the second side plate 420 and a spacer 434 having a thickness corresponding to the engagement plate 413 of the first side plate 410. Is interposed by a plate mounting pin 432.

As described above, when the first side plate 410 and the second side plate 420 are erected on the pallet 100, the engagement pins 424 of the second side plate 420 are formed on the engagement plates 413 of the first side plate 410. The engagement pin fitting hole 414 is penetrated. In this state, when the rotary side plate locking plate 431 is rotated so that the engagement groove 433 is engaged with the engagement pin 424 as shown in FIG. 6B, the spacer 434 is present. Thus, the rotary side plate locking plate 431 is disposed outside the engagement plate 413 of the first side plate 410. That is, as shown in FIG. 6A, the engagement plate 413 of the first side plate 410 is sandwiched between the rotary side plate locking plate 431 and the outer surface of the second side plate 420. As a result, that is, as a result of the rotary side plate locking plate 431 installed on the second side plate 420 being disposed outside the engagement plate 413, the engagement pin 424 may be detached from the engagement pin fitting hole 414. This prevents the second side plate 420 from tilting toward the inside of the container.
As a result, the first side plate 410 and the second side plate 420 erected on the pallet 100 are separated from the adjacent first side plate 410 and second side plate 420 at the four corners. Engaged impossible.

  The plate clamping mechanism 430 is arranged at the upper left and right ends of each of the two second side plates 420 arranged to face each other, that is, at a total of four locations. That is, when the first side plate 410 and the second side plate 420 are erected on the pallet 100, the side plates are engaged by the plate clamping mechanism 430 at each of the four corners.

The rotary side plate locking plate 431 in the state where the engagement groove 433 is engaged with the engagement pin 424 rotates the other end 431a side upward, whereby the engagement pin of the engagement groove 433 is engaged. The engagement with 424 is released, and the state where the rotary side plate locking plate 431 sandwiches the engagement plate 413 of the first side plate 410 with the outer surface of the second side plate 420 is also released.
As a result, when the second side plate 420 is tilted inward in this state, the engagement pin 424 is detached from the engagement pin fitting hole 414 and the upper portions of the first side plate 410 and the second side plate 420 are separated. The engagement state at the corner portion is also released, and the first side plate 410 and the second side plate 420 can be detached or folded.
In this way, the plate clamping mechanism 430 switches the standing state and the folded state of the second side plate 420 and the first side plate 410.

The lid member 500 is a lid member for closing the upper opening of the accommodation space of the container 1 formed by the first side plate 410 and the second side plate 420 erected on the pallet 100.
Similarly to the first side plate 410, the second side plate 420, and the floor plate 300, the lid member 500 is also made of, for example, a plastic cardboard, a metal plate, a plywood, a fiber plate, or the like.
A locking projection 510 is formed on the upper surface of the lid member 500 so that the containers 1 can be stacked one after another in a state where the article is accommodated or folded. The locking projection 510 is formed in an arrangement and shape that engages with a locking recess (not shown) on the lower surface of the pallet 100.

In the container 1 having such a configuration, when stored or transported without containing articles, the two opposing second side plates 420 and the two opposing first side plates 410 are on the pallet 100. It is folded in this order, and the lid member 500 is further placed thereon and stored, for example, by being stacked in sequence.
When such an assembly-type container 1 is used, that is, when a desired article is accommodated, first, two opposing first side plates 410 are erected along the first frame portion 210. Since the first side plate 410 is folded on the pallet 100, the first side plate 410 is placed in an upright state by supporting the upper portion and lifting the lower edge as a rotation axis.

  After the first side plate 410 is erected, the second side plate 420 is erected next. Similarly, by pulling the band 428 attached to the outer surface of the second side plate 420, the second side plate 420 folded on the pallet 100 is caused to have the lower edge as a rotation axis. Thereby, the 2nd side plate 420 will be in an erected state between the 1st side plates 410 erected previously. At this time, the removal prevention pin 427 of the second side plate 420 is inserted into the removal prevention pin insertion hole 227 of the second frame portion 220, and as a result, the second side plate 420 is in contact with the second frame portion 220. So that it cannot be pulled upward. In addition, the second side plate 420 is in contact with the engagement plate 413 of the first side plate 410, whereby the engagement pins 424 formed on both upper sides of the second side plate 420 are in contact with the first side plate 420. 410 is engaged with the engagement pin fitting hole 414 of 410.

  Then, when the second side plate 420 is erected along the first side plate 410, the rotary side plate locking plate 431 of the plate clamping mechanism 430 of the second side plate 420 is rotated to rotate the first side plate. The engagement groove 433 of the rotary side plate locking plate 431 is engaged with the engagement pin 424 outside the engagement plate 413 of 410. As a result, the second side plate 420 is maintained in a state where the engagement plate 413 of the first side plate 410 is sandwiched, and both the second side plate 420 and the first side plate 410 are prevented from falling onto the pallet 100. The standing state is maintained.

  In this state, the removal prevention pin 427 of the second side plate 420 is fitted into the removal prevention pin insertion hole 227 of the second frame portion 220, and the engagement pin 424 of the second side plate 420 is fitted to the first side plate 420. The side plate 410 is fitted into the engagement pin fitting hole 414. Further, the side plate position defining pin 425 of the second side plate 420 is in a state of being pressed upward by the side plate position defining pin 415 of the first side plate 410. As a result, the lower frame 200, the first side plate 410, and the second side plate 420 are integrated to form a container that can appropriately accommodate and protect an arbitrary article.

When transporting the assembled container 1 after the conveyance of the article is completed, the rotary side plate locking plate 431 of the plate clamping mechanism 430 is rotated in a direction in which the engagement pin 424 is removed from the engagement groove 433. Thus, the second side plate 420 can be folded inward (above the pallet 100).
When the two opposing second side plates 420 are folded on the pallet 100, the first side plate 410 can be folded on the pallet 100 as well. As a result, the assembly-type container 1 is in a state in which four side plates are folded on the pallet 100, and can be stored and transported in a small volume.

Further, in the assembled container 1, when it is desired to remove the side plate for cleaning or repair, the first side plate 410 is first lifted upward from the folded state of the assembled container 1, and the side plate position defining pin 415 is moved to the first position. 1 is extracted from the groove 215 of the frame portion 210. As a result, the first side plate 410 is separated from the pallet 100.
In addition, after the first side plate 410 is removed, the side plate position defining pin 415 of the first side plate 410 that has pressed the side plate position defining pin 425 of the second side plate 420 is removed, so that the second Similarly, the side plate 420 can be extracted upward.
That is, the assembly-type container 1 can be disassembled by disengaging the first side plate 410 and the second side plate 420 by such a simple method. As a result, the side plate can be replaced, cleaned, and washed. Etc. can be performed easily.

Thus, the assembly-type container 1 of the present embodiment can be easily assembled and disassembled, and when assembled, an arbitrary object can be appropriately accommodated therein. Moreover, when dismantled, the volume can be reduced.
Further, the normal assembly method is to fold or stand the first side plate 410 and the second side plate 420 on the pallet 100, and each side plate is assembled while being connected to the pallet. Therefore, damage and loss due to separation of the side plate can be prevented. On the other hand, when it is desired to separate the side plates, the side plates may be sequentially extracted upward from the state in which the side plates are folded. Therefore, it can be separated by a simple method when necessary.

  Further, in the assembly type container 1 of the present embodiment, the plate clamping mechanism 430 is configured such that the rotary side plate locking plate 431 is installed on the second side plate 420 from the outside by the plate mounting pin 432 with the spacer 434 interposed therebetween. is there. Therefore, the structure is very simple, and members such as screws, rivets, bolts or nuts that may fall out of the container are not used. Therefore, it is possible to reduce the possibility of foreign matters entering the container.

  The present invention is not limited to the above-described embodiment, and can be variously modified within the scope of the present invention.

For example, the configuration of the plate clamping mechanism 430 of the above-described embodiment can be further modified in some suitable manner.
For example, the plate clamping mechanism 430 described above simply engages the engagement pin 424 with the engagement groove 433 of the rotary side plate locking plate 431 by simply rotating the rotary side plate locking plate 431, or The engagement state is maintained by the weight of the rotary side plate locking plate 431. However, the rotary side plate locking plate 431 rotates unintentionally due to the inclination or vibration of the container, and the engagement state of the engagement groove 433 and the engagement pin 424 is not intended, for example, it is released during the conveyance of the article. It is effective to prevent this. Therefore, it is good also as a structure which provides the mechanism which prevents rotation of the rotary side plate latching plate 431. FIG.

Specific examples of such a configuration are shown in FIGS.
FIG. 7 shows a configuration in which a rotation stopper 440 is provided at the end of the rotary side plate locking plate 431 on the side where the plate mounting pin 432 is disposed so that the rotary side plate locking plate 431 does not easily rotate. It is. The rotation stopper 440 includes a rotation stopper plate 441 and a pin 442 that is rotatably mounted on the second side plate 420. The rotation stop plate 441 is a plate-like member formed so as to be rotatable about the pin 442 as a rotation axis, and is a specific planar member whose distance from the pin 442 to the periphery is asymmetric. In the rotation stopper 440, the rotation stopper plate 441 is arranged in a posture in which a specific side having a long distance from the pin 442 is in contact with the end side of the rotary side plate locking plate 431, as shown in FIG. As shown, both the rotary side plate locking plate 431 and the rotation stop plate 441 are in a non-rotatable state. When rotating the rotary side plate locking plate 431, the rotation side plate locking plate 431 is prevented from rotating by rotating and rotating the rotation stop plate 441 in a specific direction, such as by pulling the rotation stop plate 441 upward and rotating it. The state is released, and the rotation side plate locking plate 431 can be rotated.
By installing such a rotation stopper 440, the rotary side plate locking plate 431 rotates unintentionally and the engagement state between the first side plate 410 and the second side plate 420 is released. Can be prevented.

FIG. 8 shows that the spring 435 is installed so that the engaging groove 433 of the rotary side plate locking plate 431 is always urged to the engaging pin 424 in the plate clamping mechanism 430 of the above-described embodiment. This is the configuration. The spring 435 is a coil spring as shown in FIG. 8C, for example, and is installed around the plate mounting pin 432 as shown in FIG. ), The second side plate 420 is set as a fulcrum so that the spring force acts on the rotary side plate locking plate 431.
Even when the plate clamping mechanism 430 has such a spring 435, the rotary side plate locking plate 431 rotates unintentionally and the first side plate 410 and the second side plate 420 are engaged. Accidents such as the release of the state can be prevented.
When the first side plate 410 and the second side plate 420 are engaged and installed, or when the engagement is released and the second side plate 420 is disengaged or folded, the rotary side plate locking plate resists the spring force of the spring 435. By moving 431 upward, the engagement between the engagement groove 433 and the engagement pin 424 is released, and the first side plate 410 and the second side plate 420 are engaged or disengaged.
