JP 2001-364467 A

  2. Description of the Related Art Conventionally, in the transportation industry and the like, a box-shaped container has been widely used for transporting large parts such as automobile parts with a large weight and size. Further, as such a transporting box-like container, for example, a container using a metal such as iron or an alloy is widely used instead of a wooden container.

The metal transport box-like container as described above is generally an assembly type. That is, one transport box-like container is composed of, for example, at least one bottom panel and four side panels, and is assembled using these panels. When assembling the transporting box-like container, bolts and nuts are used.
In other words, assembling work of the transporting box-like container, the bolt holes formed at several places are aligned at predetermined positions on the edge side of the panels to be connected, and bolts and nuts are aligned with the bolt holes. It was going to be concluded using.

However, when assembling the transporting box-shaped container as described above, it is necessary to tighten bolts and nuts for all bolt holes provided for each panel. It takes a lot of time and effort.
Therefore, as shown in Patent Document 1, the applicant previously proposed a technique capable of assembling a box-shaped container without using bolts and nuts.
In the box-shaped container described in Patent Document 1, each panel is connected by using a disengagement mechanism at the end portion thereof, so that bolts and nuts are not required and assembly is facilitated.

However, although the box-shaped container of Patent Document 1 is certainly easy to assemble by the boltless structure, it requires some knack for assembling, and further, a corner part and a fixing auxiliary part (corner mounting part) for reinforcing the fixing. There was a point that improvement was desired.
Therefore, the present invention further facilitates the assembly than the box-shaped container of Patent Document 1 described above, and eliminates the need for fixing auxiliary parts such as a corner mounting portion, and simplifies the configuration in consideration of work efficiency at the site. The purpose is to do.

The present invention has been made in consideration of the above-described problems, and the box-shaped container of the present invention includes a bottom panel having a substantially rectangular planar outer shape, and a pair of first sides facing each other in the bottom panel. And a pair of second side panels arranged with respect to a pair of second side portions facing each other in the bottom panel.
And each said 1st side panel is attached to the said bottom panel by the 1st engaging mechanism provided in the lower part of this 1st side panel, and the 1st edge part of the said bottom panel. Each of the second side panels has a lower portion of the second side panel positioned on the second side of the bottom panel, and a side end of the second side panel. The second engaging mechanism provided in each first side panel is fixed to each first side panel.
That is, the box-shaped container is configured by only five panels, that is, a bottom panel (base), two first side panels (end panels), and two second side panels (side panels). Then, the two first side panels are connected and fixed to the bottom panel by the first engagement mechanism, and each second side panel is second with respect to the pair of first side panels opposed in that state. Are connected and fixed by the engagement mechanism. Thus, a structure is adopted in which the four side panels are connected and fixed to the four flat sides of the bottom panel while being connected to each other.

Here, the first engagement mechanism includes an engagement pin and a pin engagement hole, which are provided on the first side panel side and the bottom panel side, respectively, and the engagement pin serves as the pin engagement hole. The structure is inserted and locked. Thus, the two first side panels can be connected and fixed to the bottom panel by simply engaging the engagement pins with the pin engagement holes.
The engaging pin has a shape in which a tip locking portion is formed at a tip of a columnar portion, and the pin engaging hole includes an insertion hole portion through which the tip locking portion can be inserted, and the insertion hole portion. It has a shape that has a locking hole portion that is positioned obliquely below and locks the tip locking portion so as not to be inserted, and a connecting hole portion that connects the insertion hole portion and the locking hole portion.
Then, with the leading end locking portion of the engagement pin being inserted into the insertion hole portion in the pin engagement hole, the columnar portion is guided to the locking hole portion through the connection hole portion, thereby By being configured to be locked and fixed by the distal end locking portion and the locking hole portion, it is possible to prevent upward “disengagement” of the engaged state at the time of connection while maintaining the ease of connection work. it can.
The second engagement mechanism includes an engagement lever and a lever engagement hole, which are provided on a side end portion of the second side panel and the first side panel, respectively. By being inserted into the engaging hole and locked and fixed, the second side panel can be easily connected in a state where the two first side panels are connected to the bottom panel. Can do.
Further, in the second engagement mechanism, the engagement lever has a shape in which a fan-shaped locking portion is formed at a tip of a lever portion having a circular cross section and is rotatably attached. The hole has a shape that allows the fan-shaped locking portion to be inserted when the engagement lever is in a predetermined rotational position. In the second engagement mechanism, after the lever portion is in the predetermined rotation position state and the fan-shaped locking portion is inserted into the lever engagement hole, the lever portion is rotated in the other direction. By being in the position state, the fan-shaped locking portion and the lever engagement hole are locked and fixed.

  According to the present invention, five panels, that is, a bottom panel (base), two first side panels (end panels), and two second side panels (side panels) are combined without using bolts and nuts. A box-shaped container can be assembled, and the assembly work is very easy. Further, by being composed of only these five panels, the ease and efficiency of assembly work in the field are improved. In addition, since a small separate auxiliary part is not required, it is convenient for parts management such as storage or transportation in a disassembled state.

When connecting the first side panel to the bottom panel, it is only necessary to engage the first engaging mechanism including the engaging pin and the pin engaging hole, and the operation is very easy. Further, the provision of the engagement pin and the pin engagement hole has an advantage that the engagement method at the time of assembly is easily understood.
The engaging pin has a shape in which a tip locking portion is formed at a tip of a columnar portion, and the pin engaging hole includes an insertion hole portion through which the tip locking portion can be inserted, and the insertion hole portion. The engaging hole is positioned obliquely below and locks the tip locking portion so as not to be inserted, and has a shape having a connecting hole that connects the insertion hole and the locking hole. In a state where the tip end locking portion of the pin is inserted into the insertion hole portion in the pin engaging hole, the columnar portion is guided to the locking hole portion through the connecting hole portion, and the tip end locking portion and the engaging portion are engaged. By being configured to be locked and fixed by the perforated part, it is possible to prevent “disengagement” of the engaged state after assembling and maintain a strong connected and fixed state while maintaining the ease of connecting work. it can.

Further, the second engagement mechanism includes an engagement lever and a lever engagement hole, which are provided on the side end portion of the second side panel and the first side panel, respectively. Is inserted into the engagement hole and locked and fixed, so that the second side panel is connected between the first side panels in a state where the two first side panels are connected to the bottom panel. The side panels can be positioned and easily connected. In other words, after positioning the second side panel with respect to the bottom panel, the side end of the second side panel may be fixed between the first side panels with the engaging lever, and no excessive force is required for the work. And it can work reliably. Further, the second engagement mechanism including the engagement lever and the lever engagement hole has an advantage that the assembling method can be understood at a glance.
Further, in the second engagement mechanism, the engagement lever has a shape in which a fan-shaped locking portion is formed at a tip of a lever portion having a circular cross section and is rotatably attached. The hole has a shape that allows the fan-shaped locking portion to be inserted when the engagement lever is in a predetermined rotational position. In the second engagement mechanism, after the lever portion is in the predetermined rotation position state and the fan-shaped locking portion is inserted into the lever engagement hole, the lever portion is moved to another rotation position. By being in a state, the fan-shaped locking portion and the lever engagement hole are locked and fixed. Accordingly, the second side panel is firmly connected and fixed between the two first side panels.

And from the above, it has a simple structure of 5 panels, and it can be assembled easily and quickly by engaging each panel without using bolts and nuts, and is firmly fixed when connected. The effect that the box-shaped container which can maintain can be implement | achieved is acquired.
Of course, it is only necessary to perform the reverse operation of the assembly at the time of disassembly, and in this case, the effect of facilitating and speeding up can be obtained.

Hereinafter, a box-shaped container according to an embodiment of the present invention will be described with reference to the drawings.
As a box-shaped container according to the present embodiment, for example, a box-shaped container for transportation which contains a relatively heavy transported object such as an automobile part and is transported by being loaded on a container for transportation is taken as an example. I will do it.
The description will be made in the following order.

1. Overall panel configuration

The exploded perspective view of FIG. 1 shows the overall structure of a transport box-like container as the present embodiment.
As shown in this figure, the box-shaped container of this example includes a base 1 having a rectangular planar shape as a bottom panel, a pair of end panels 2 and 3 forming side surfaces in the longitudinal direction as side panels, and a short side. 5 panels of a pair of side panels 4 and 5 which form the side surface of a direction are provided.
Each of the base 1, the end panels 2 and 3, and the side panels 4 and 5 is made of metal such as iron or an alloy containing iron. Then, by combining members formed by processing such metal into a required shape by spot welding or the like, a structure as a frame is formed as shown in the figure.

And as a basic structure of the box-shaped container 100 for conveyance of this Embodiment, it can obtain by combining the above-mentioned five panels by mutually connecting by the positional relationship shown in figure.
Although the mechanism for the connection will be described later, the end panels 2 and 3 are engaged with the side end portion (first side portion) of the base 1 in the longitudinal direction. After positioning the lower part of the side panel on the side end part (second side part) of the base 1 in the short direction, the side end parts of the side panels 4 and 5 are engaged with the end panels 2 and 3. By combining, a rectangular parallelepiped box-shaped box-shaped container is assembled as shown in FIG.

2. Base (bottom panel)

The structure of the base 1 will be described with reference to FIGS. 1, 2, 3, 4 and 5.
2A, 2B, and 2C are a plan view, a front view, and a side view of the base 1, respectively. 3 is an explanatory view of a pin engaging hole provided in the base 1, and FIGS. 4 and 5 are enlarged perspective views of corner portions of the base 1. FIG.

As can be seen from FIGS. 1 and 2, the base 1 forming the bottom surface of the box-shaped container is a planar rectangular member.
Basically, a pair of outer frame members 11 that form a short side of a planar rectangle and a pair of outer frame members 14 that form a longitudinal direction are combined to form a rectangular planar shape. The outer frame member 14 is formed of, for example, a square pipe iron material.
On the inner side of the rectangular shape formed by the outer frame members 11 and 14, for example, three bottom reinforcing members 12 are formed in the short direction. In the example of this figure, the bottom surface reinforcing member 12 is provided only in the short direction, but the bottom surface reinforcing member is provided in the longitudinal direction, or the bottom surface reinforcing member is provided in a lattice shape in the short direction and the longitudinal direction. Sometimes. The configuration of these bottom reinforcing members may be designed according to the bottom shape and size of the box-shaped container.

The outer frame members 11 and the three bottom surface reinforcing members 12 on both sides arranged in parallel in the short-side direction have the same height on the upper surface, and the upper surface of the outer frame member 11 and the bottom surface reinforcing member 12 are on the upper surface. In a state where the flat plate member 13 forming the loading bottom surface of the box-shaped container is placed, it is fixed by welding, for example.
The outer frame member 14 in the longitudinal direction is also welded and fixed to the upper surface sides of the outer frame member 11 and the bottom surface reinforcing member 12. Alternatively, when the length in the short direction of the flat plate member 13 is the same size as the length of the outer frame member 11 and the bottom surface reinforcing member 12, the outer frame member 14 is placed on the side in the longitudinal direction of the flat plate member 13. It may be fixed.
In any case, the outer frame member 14 protrudes upward in a frame shape on both sides in the longitudinal direction of the loading bottom surface of the box-shaped container formed by the flat surface of the flat plate member 13.
As will be described later, the end panels 2 and 3 are fixed to the upper surface 14a of the outer frame member 14 in a stacked state.
Although depending on the load, the flat plate member 13 is not necessarily provided. For example, the bottom reinforcing member may be formed in a lattice shape as described above, and the bottom reinforcing member may be the loading bottom surface.
When the outer frame member 11 and the bottom reinforcing member 12 are formed as shown in FIG. 2, the fork portion of the forklift can be inserted into the lower portion of the base 1, which is convenient for transporting the box-shaped container by a forklift or the like. It is.

Each outer frame member 14, 14 has an engagement plate 18 welded and fixed at three locations on the inner surface thereof. As shown in FIGS. 4 and 5, the engagement plate 18 is, for example, a card-shaped iron plate, and as a pin engagement hole with which an engagement pin 38 of the end panel 2 described later is engaged, A locking hole 18c positioned obliquely below the insertion hole 18a and a connecting hole 18b for connecting the insertion hole 18a and the locking hole 18c are provided.
The width of the connecting hole 18b and the diameter of the substantially circular locking hole 18c are approximately half the diameter of the substantially circular insertion hole 18a. Then, the connecting hole 18b is formed in a shape that extends slightly downward from the circular insertion hole 18a and then continues obliquely downward. Further, the locking hole 18b is formed in the connecting hole 18b that extends obliquely downward. The end has a circular shape dropped one step down.
Here, the shapes of the insertion hole 18a, the connection hole 18b, and the locking hole 18c as pin engagement holes will be described in detail with reference to FIG.
FIG. 3A shows the shape of the pin engagement hole according to the present embodiment, and FIGS. 3B and 3C refer to the shape of the pin engagement hole considered in the development process of the present embodiment. Therefore, it is shown.
In FIG. 3B, a substantially circular locking hole portion 18c is formed with the center C1 of the terminal line L1 of the connecting hole portion 18b traveling obliquely downward as the center point.
FIG. 3C shows a substantially circular locking hole portion 18c with a center point at a position C2 lowered from the center C1 by a distance B.
On the other hand, as shown in FIG. 3A, the shape of the pin engaging hole in this example is a distance just below the center C1 of the terminal line L1 of the connecting hole portion 18b by a distance B and further to the left in the drawing. A substantially circular locking hole 18c is formed with the position C3 moved by A as the center point. Here, the distance A is suitably about ¼ to ５ of the diameter of the circle as the locking hole 18c.
The meaning of the pin engagement hole having the shape shown in FIG. 3A in this example will be described later.

As can be seen from FIGS. 1 and 2 (c), the engagement plate 18 is fixed by being welded to a predetermined position on the inner side of the outer frame member 14 below the pin engagement holes (18a, 18b, 18c). Yes.
Each engagement plate 18 is attached such that its pin engagement holes (18a, 18b, 18c) flow in the left direction when viewed from the outside of the outer frame member 14. That is, when viewed from the outside, the locking hole portion 18c is located on the lower left side with respect to the insertion hole portion 18a, and the connection hole portion 18b is configured to connect the locking hole portion 18c from the insertion hole portion 18a to the lower left diagonal direction. .

Corner members 15 and 16 are welded to each corner portion of the outer frame formed by the outer frame members 11 and 14 to reinforce the coupling of the outer frame members 11 and 14.
Here, for example, when viewed from the end panel 2 side in FIG. 1, a corner member 15 is provided at the left corner of the outer frame member 14 on which the end panel 2 is stacked, and a corner member 16 is provided at the right corner.
As described above, the engagement plate 18 fixed to the outer frame member 14 on which the end panel 2 is stacked is formed so that its pin engagement holes (18a, 18b, 18c) flow downward to the left. When the pin engaging holes (18a, 18b, 18c) are attached so as to flow downward to the left, the left side of the outer frame member 14 becomes the corner member 15, and the right side becomes the corner member 16.
Even when viewed from the other end panel 3 side in FIG. 1, the positional relationship is the same. Therefore, the corner members 15 and 15 are provided at the corners on the diagonal of the plane rectangle of the base 1, and the corner members 16 and 16 are similarly provided at the corners on the diagonal.
Hereinafter, for the sake of explanation, the corner to which the corner member 15 is attached is referred to as a left corner and the corner to which the corner member 16 is attached is referred to as a right corner with reference to the directionality of the outer frame member 14 viewed from the outside.

The left corner is enlarged and shown in FIG. 4 and the right corner is shown in FIG. As can be seen with reference to FIGS. 4 and 5 and FIGS. 1 and 2, each of the corner members 15 and 16 is formed by folding a steel plate material so as to cover the corner, and a part of the inner surface side is outside. The frame members 11 and 14 are welded and fixed. The corner member 15 at the left corner is provided with a regulation surface 15a that forms a surface at the end position of the outer frame member 14, but the corner member 16 at the right corner forms a surface corresponding to the regulation surface 15a. Instead, they are notched portions 16a.
As described above, the pin engagement holes (18a, 18b, 18c) are formed to flow downward to the left, and the end panels 2, 3 are engaged with the pin engagement portions (18a, 18b, 18c). In order to do this, after the end panels 2 and 3 are positioned slightly to the upper right from the fixed position, an operation of moving the end panels obliquely to the lower left is performed (described later). At this time, since the notch 16a is provided in the corner member 16, the operation can be performed without any trouble.
Contrary to this example, if the engagement plate 18 is attached so that the pin engagement holes (18a, 18b, 18c) flow to the lower right when viewed from the outside, the corner member 16 on the right corner is reversed. In this case, a restriction surface is provided, and a notch is formed in the corner member at the left corner.

Further, a stacking plate 17 formed by bending a flat iron plate by 90 ° is provided on the inner surface side of the left corner and the right corner. The lower side of the stacking plate 17 is welded to the inner surface side of the outer frame member 14, and the side surface is welded to the inner side of the corner member 15 or 16.

FIG. 11B shows the positional relationship between the engagement pin 38 in the end panel 3 and the engagement plate 18 (pin engagement holes (18a, 18b, 18c)) in the base 1 in an enlarged manner. Of course, in this state, the engagement pin 38 is above the engagement plate 18.

Subsequently, the operator moves the end panel 3 downward toward the upper surface 14 a of the outer frame member 14 as shown in FIG. 12A, and each of the three engagement pins 38 is inserted through each engagement plate 18. The end panel 3 is applied to the engagement plate 18 so as to enter the hole 18a. Then, as shown in FIG. 12B, the engagement pin 38 is inserted into the insertion hole 18a. At this time, the lower collar 33 of the end panel 3 is still slightly above the upper surface 14 a of the outer frame member 14 of the base 1.
At this time, the end panel 3 is slightly shifted from the final connection and fixing position to the right corner side of the base 2, that is, the side where the corner member 16 is provided. In FIG. 12, since it is the figure seen from the inside of a box-shaped container, the left side on the drawing is the right corner side where the corner member 16 is provided.
In this case, since the corner member 16 is provided with the notch 16a as described above, the outer frame support 32 of the end panel 3 does not collide with the corner member 16, and the position state as shown in FIG. It has become.

Next, from the state where each of the engagement pins 38 is inserted into the insertion hole 18a of each engagement plate 18 as described above, the operator engages the engagement hole 38 through the connection hole 18b. The end panel 3 is moved obliquely downward so as to reach 18c.
Since the front end locking portion 38a of the engaging pin 38 has already been inserted through the engaging plate 18, the columnar portion 38b of the engaging pin 38 reaches the locking hole portion 18c through the connecting hole portion 18b.
When the engaging pin 38 reaches the locking hole 18c, the lower end 33 of the end panel 3 is stacked on the upper surface 14a of the outer frame member 14 of the base 1 as shown in FIG. It becomes a state.
As shown in FIG. 13B, the columnar portion 38b of the engaging pin 38 is inserted into the locking hole 18c, and the tip locking portion 38a is positioned on the inner surface side of the locking hole 18c. Therefore, the tip locking portion 38a is locked by the locking hole 18c.

Thus, the attachment of the end panel 3 to the base 1 is completed. That is, as shown in FIG. 13, in the state where the end panel 3 is loaded on the upper surface 14 a of the outer frame member 14, the three engagement pins 38 are locked by the locking holes 18 c of the respective engagement plates 18. Thus, the end panel 3 is connected to stand on one side in the longitudinal direction of the base 1.
Similarly, the other end panel 2 is connected and fixed while being stacked on the upper surface 14a of the other outer frame member 14.
As a result, as shown in FIG. 14, the end panels 2 and 3 are attached to the base 1 on opposite sides in the longitudinal direction.

Subsequently, the worker sequentially attaches the side panels 4 and 5. The order of attaching the side panels 4 and 5 is also arbitrary.
For example, the operator lifts the side panel 4 and first causes the positioning projection 19 on the base 1 to be fitted into the lower end 52 a of the column 52.
In this state, both ends of the upper collar 51 of the side panel 4 are applied to the outer frame columns 32 of the end panels 2 and 3 standing on both sides.

At this time, first, as shown in FIG. 15A, when the engaging lever 55 is pulled in the direction of the arrow A and the end of the upper collar 51 is applied to the outer frame support 32, the fan-shaped engagement of the engaging lever 55 is performed. The stop 55a is kept out of the way.
In a state where the end portion of the upper collar 51 is applied to the outer frame support column 32, the fan-shaped locking portion 55 a is positioned in front of the lever engagement hole 37 in the outer frame support column 32.
From this state, the operator rotates the engagement lever 55 by lifting the handle portion 55d of the engagement lever 55 to the horizontal position, and further moves the engagement lever 55 in the direction of arrow B in FIG. To extrude. Then, the fan-shaped locking part 55 a passes through the lever engagement hole 37 and reaches the inside of the outer frame support 32.
Next, the operator returns the rotation position of the engagement lever 55 so that the handle portion 55d faces downward. Then, the fan-shaped locking part 55a cannot be removed from the lever engaging hole 37, that is, the side panel 4 is engaged with the outer frame column 32 of the end panel 2 (or 3).
At this time, as can be seen from FIG. 15 (c), in the state where the fan-shaped locking portion 55 a is in contact with the lever engagement hole 37 at the taper portion 55 b, the handle portion 55 d is connected to one lever receiving portion 56. In other words, the engagement lever 55 is not pushed further in the B direction.
In other words, in a state where the engagement lever 55 is pushed out to the maximum in the B direction (a state in which the handle portion 55d is in contact with the lever receiving portion 56), the taper portion 55b is pressed against the lever engagement hole 37 and is fan-shaped locked. The dimensions of each part are designed so that the part 55a is locked. Such engagement by the engagement lever 55 and the lever engagement hole 37 engages the upper collar 51 of the side panel 4 and the outer frame column 32 of the end panel 2 so as to attract each other firmly.

When the operator completes the engagement by the engagement lever 55 and the lever engagement hole 37 at one end portion of the upper collar 51, of course, the engagement lever 55 and the lever engagement are similarly performed at the other end portion. Engage with the holes 37.
If engagement is performed at both ends, the attachment of the side panel 4 is completed. Thereafter, the other side panel 5 may be attached in exactly the same manner.
With both of the side panels 4 and 5 attached as described above, the assembly of the box-shaped container is completed as shown in FIG.

That is, the box-shaped container of this example has the end panels 2 and 3 on the upper surface 14 a of each outer frame member 14 that is the side in the longitudinal direction of the base 1, and the engagement pins 38 are the engagement holes of the engagement plate 18. Then, the side panels 4 and 5 are first positioned and fixed on the side panels 4 and 5 by the positioning projections 19 on the side portions of the base 1 in the short direction, and the upper ends are then fixed. The assembly is completed by completing the engagement state of the engagement lever 55 and the lever engagement hole 37 with respect to the end panels 2 and 3 on both sides.
Needless to say, the assembly can be performed very simply and quickly. Further, at the time of dismantling, it is only necessary to reverse the above procedure, and this can also be executed easily and quickly.

Moreover, in this example, a box-shaped container is firmly formed with only five panel members.
The end panels 2 and 3 are only connected to the base 1 by engagement pins 38. Further, the lower rods 33 of the end panels 2 and 3 are only stacked on the upper surface 14 a of the outer frame member 14.
However, in the assembled state as shown in FIG. 16, since both ends of the end panels 2 and 3 are engaged with the side panels 4 and 5, the end panels 2 and 3 cannot move left and right. The end panels 2 and 3 are not disengaged unless they are lifted obliquely upward from the shape of the pin engagement holes (18a, 18b, 18c). That is, even if the end panels 2 and 3 are lifted upward, the end panels 2 and 3 cannot move to the left and right, so that the engaging pin 38 moves obliquely upward and comes out of the locking hole 18c (the connecting hole portion). 18b), the engagement state at the locking hole 18c is maintained. Therefore, in the assembled state, the end panels 2 and 3 are not disengaged.
In other words, at the time of mounting, after the assembly, the engaging pin 38 is merely a simple engaging operation in which the connecting hole 18b is traced from the insertion hole 18a to the locking hole 18c. The engagement state can be maintained firmly.

In particular, as described with reference to FIG. 3, in the case of this example, as shown in FIG. 3A, the locking hole portion 18c is below the center C1 of the terminal end L1 of the connecting hole portion 18b and to the left (see FIG. 3). 3 is a substantially circular shape centered on a point C3 displaced in the left direction on the drawing 3). That is, it can be said that the locking hole portion 18c is formed as a position that is dropped downward from the end of the connecting hole portion 18b and is shifted in the lateral direction.
Actually, when the end of the connecting hole 18b is used as the engaging hole 18c as shown in FIG. 3B, or when the end of the connecting hole 18b is dropped downward as shown in FIG. 3C. Compared with the case where the hole 18c is formed, the shape shown in FIG. 3A increases the fixing force of the end panels 2 and 3. That is, when the end panels 2 and 3 are lifted upward, the shape of FIG. 3A is optimal as a shape that does not cause the engaging pin 38 to move obliquely upward and come out of the locking hole 18c. It was there.

Further, as described above, the engagement by the lever engagement hole 37 and the engagement lever 55 between the end panels 2 and 3 and the side panels 4 and 5 is also engaged so that the engagement lever 55 pulls the lever engagement hole 37. By joining, a strong connected state is maintained.
Thus, sufficient strength as a box-like container is maintained. Furthermore, since a sufficient strength is maintained, an auxiliary small member is not necessary. Therefore, only five panel members are required for the box-shaped container, the configuration is simplified, and the need for small parts and reinforcing members is eliminated. Less.

In the case of this example, as described with reference to FIG. 8, the tip locking portion 38a of the engagement pin 38 has a circular shape with the upper portion cut away. Thereby, the workability at the time of inserting the engaging pin 38 into the insertion hole 18a of the pin engaging hole at the time of assembly or removing the engaging pin 38 from the insertion hole 18a at the time of disassembly is improved. That is. When the operator tries to insert the engaging pin 38 into the insertion hole 18a as shown in FIG. 12, the operator should have a margin in the vertical position of the end panel 3 when the end panel 3 is applied to the engaging plate 18. As a result, the operation of inserting the distal end locking portion 38a into the insertion hole portion 18a is facilitated. The same applies when disassembling, with the end pin 3 being lifted, the engaging pin is advanced from the locking hole 18c to the connecting hole 18b, and moved to the insertion hole 18a to some extent in the vertical direction. The distal end locking portion 38a can be detached from the insertion hole portion 18a while having a sufficient margin.
In other words, the circular shape with the tip locking portion 38a cut out also contributes to the ease of assembly and disassembly work.

By the way, when the box-shaped container of this example is disassembled, the members can be combined as shown in FIG.
That is, the side panels 4 and 5 are first placed on the flat plate member 13 of the base 1, and one end panel (for example, the end panel 3) is placed thereon, and the other end panel (for example, the end panel 2) is placed thereon. Are put together.
At the time of disassembly, the side panels 4 and 5 are first removed in the reverse order of the assembly described above, but the two side panels 4 and 5 are put on the flat plate member 13 of the base 1 in a laid state. . At this time, since the side panels 4 and 5 have a substantially triangular shape, the two side panels 4 and 5 can be alternately laid on the flat plate member 13 as shown in FIG.
Subsequently, one end panel 3 is removed and laid on the side panels 4 and 5. Finally, the other end panel 2 is removed and laid down on the end panel 3. Then, the state shown in FIG. 17 is obtained.
That is, while performing the removal work, it can be naturally collected in the state shown in FIG. 17 that is convenient for storage in the dismantled state. Further, in this dismantled state, it is in a state that fits within the size of the base 1 and is suitable for storage.
Further, as can be seen from FIG. 17, in the dismantled state, each loading plate 17 attached to the corner members 15, 16 has its upper planes positioned at the four corners. The end panels 2 and 3 and the side panels 4 and 5 are stored below the height position of the upper surface of the stacking plate 17. Further, the upper surface of the stacking plate 17 is a position corresponding to the outer frame member 11.
The loading plate 17 is used for loading a plurality of box-shaped containers in the dismantled state.
That is, the box-shaped containers disassembled as shown in FIG. 17 can be stacked by placing the outer frame member 11 on the loading plate 17 of another box-shaped container similarly disassembled. For this reason, it becomes suitable also for storage and conveyance in the state which disassembled many box-shaped containers.
