Description

[Detailed description of the invention] Industrial application field This invention is manufactured in the technical field of plastic molding and processing, and is used for storing or transporting bolts, nuts, or small mechanical parts. It relates to a prefabricated transportation box, in which a frame of the box is assembled by connecting pipes or rod-shaped aggregates with joints, and a plurality of plate-like panels of approximately the same shape and size are attached to this frame. The present invention relates to an assembly-type transport box in which side walls and bottom walls of the box are formed by assembly, and the top surface is open.

BACKGROUND ART Conventionally, transportation boxes (including packaging boxes) have been used to store bolts, nuts, relatively small mechanical parts, and the like.
(hereinafter the same applies) are usually integrally molded as plastic injection molded products.

In addition, an assembly-type transportation box assembled from aggregate and a plurality of panels attached to the aggregate is also known (for example, the boxes described in Japanese Utility Model Publication No. 44-21676, Publication Utility Model Publication No. 46-25894, etc.).

Problems that the present invention aims to solve The conventional method of integrally molding using the injection molding method requires a dedicated mold for each case to meet the diverse needs of transport boxes of different sizes, shapes, and structures. There is no choice but to create and manufacture it. Therefore, there is a drawback that the design and manufacturing costs of the mold are high, and the manufacturing cost of the transport box is also high. Another problem is that the delivery date is delayed due to the number of days required for mold production and the molding schedule.

On the other hand, an injection molding machine has a molding capacity and rating, and the size of the transport box that can be molded is approximately fixed, and there is no way to meet the demand for unnecessarily large transport boxes. That's the reality, and I'm getting used to it.

Furthermore, the transport box described in the above-mentioned Japanese Utility Model Publication No. 44-21676 is characterized by a foldable structure, and the bottom wall is a single plate structure.
Its size and shape are constant. Therefore, the technical idea is not to make it possible to manufacture transport boxes of various sizes and shapes by commonly using plate-like panels of substantially the same shape and size.

The transportation box described in Utility Model Publication No. 46-25894 has a single-plate structure on each wall, and its size and shape are constant, so it is assumed that plate-like panels are used in common. It is clear that the technical concept is not such that it is possible to manufacture transport boxes of various sizes and shapes.

Therefore, the purpose of this invention is to construct a transport box consisting of a frame made of aggregate and joints, and a plate-like panel attached to this frame, and to make the structure of the transport box by adjusting the length of the aggregate and the plate-like panel. To provide a prefabricated transport box with an opening at the top and improved in configuration so as to be able to meet a wide range of demands for transport boxes of various sizes, shapes, and structures by simply selecting the number of boxes to be used. There is a particular thing.

Means for Solving the Problems In order to solve the above-mentioned problems of the prior art, an assembly-type transport box with an open top surface according to this invention,
As shown in a preferred embodiment in the drawings, aggregates 2, 3, and 4 made of pipes or rods with uniform cross-sectional shapes are placed along each ridgeline of a rectangular parallelepiped or cubic transportation box. Each aggregate was assembled into a single frame by connecting the aggregates at their intersections with other aggregates using joints 5.

Two aggregates 2 facing each other in parallel among the aggregates
and 2 or 3 and 3 or 4 and 4, plate-like panels 6 for side walls and bottom walls having substantially the same size and shape;
7 and 8 respectively, connecting tubes 6b and 7 at both ends thereof.
b, 8b through the appropriate aggregate 2 or 3 or 4,
Thus, the number of plate-like panels necessary to form each side wall and bottom wall of the box is arranged in series along each aggregate to form the bottom wall and side wall of the box, respectively.

In addition, in the assembly-type transportation box with an open top surface according to the present invention, the plate-like panels 6, 7, and 8 for the side walls and bottom wall constituting the box are each made of plastic molded products, and the bottom wall of the box Or, the side wall is formed into a rectangular shape with a width and length equal to approximately equal parts in the longitudinal direction of the aggregate, and a cylindrical connection having an inner diameter approximately equal to the outer diameter of the aggregates 2, 3, and 4 at both ends. Tubes 6b, 7b, 8b
are integrally formed with the inner surface of the panel at a tangential position (Fig. 8). Furthermore, reinforcing ribs 6a and 7a in the shape of plates bent outward at a substantially right angle are formed on the peripheral edge of the plate-like panel, and have the same height on each side, and the heights of the connecting cylinders 6b and 7b are the same. , 8b is characterized in that it is integrally formed with a height substantially equal to the outer diameter of the members.

The present invention also provides that the connection tubes 6b, 7b, 8b of the plate panels 6, 7, 8 for the side walls and the bottom wall are individually passed through each of the aggregates 2, 3, 4 6b ₁ , 8b ₂ is formed to have the same length as the panel width, and two types of panels forming two different sides of the box are passed through in common 6b ₂ ,
7b is also characterized by being formed to have a length approximately 1/2 of the panel width (Fig. 3).

Effect Length of aggregates 2, 3, 4 and plate panels 6, 7,
By adjusting the number of sheets of 8 used, the size and form of the transport box can be designed and manufactured as desired.

Since the plate-like panels 6, 7, and 8 are commonly used, only one type or several types of molds may be used for forming the panels, and there is no need to change them.

By preparing a total of three types of parts: aggregate, joints, and plate-like panels, it is possible to easily and inexpensively meet a wide range of demands for transport boxes of various sizes and shapes.

Of course, by preparing various types of joints, aggregates, and shapes of plate-shaped panels, a wider range of possibilities can be achieved.
We can manufacture transportation boxes of various shapes and functions.

Embodiment A rectangular parallelepiped-shaped transportation box 1 with an open top surface shown in FIG. 1 is assembled with the components shown in FIGS. 2 and 3.

In the figure, 2, 3, and 4 are horizontal pipes, width pipes, and vertical pipes made of resin-coated pipes whose outer peripheries are coated with ABS resin or the like to an even thickness, and which are used as aggregates with uniform cross-sectional shapes. The outer diameter of each pipe is approximately φ28 or φ32. The horizontal pipe 2 is placed at the horizontal ridgeline of the box, the width pipe 3 is placed at the lateral ridgeline of the box, and the vertical pipe 4 is placed at the vertical ridgeline with the same length as each ridgeline. .
As an example, the length of horizontal pipe 2 is about 750mm, the length of width pipe 3 is about 450mm, and the length of vertical pipe 4 is about 300mm.
It is the rank.

In the figure, reference numeral 5 denotes a joint for connecting the intersection points of the pipes 2, 3, and 4. This joint 5 is
This is a so-called three-way joint in which cylindrical sockets are provided in three orthogonal directions with cylindrical sockets having diameters in which the pipes 2, 3, and 4 are closely fitted. The joints 5 are all the same shape and size,
It is molded from synthetic resin such as ABS resin. However, it may be made of metal such as aluminum.

Said horizontal pipe 2, width pipe 3 and vertical pipe 4
By connecting each intersection point of the transport box with a joint 5 and fixing it using a method such as gluing, a frame body that forms the basis of the strength and rigidity of the transport box is assembled.

In the figure, 6 is a plate-like panel for forming the lateral side wall of the box, 7 is a plate-like panel for forming the bottom wall,
And 8 ₁ and 8 ₂ are plate-like panels for forming the width direction side walls of the box. Each plate-like panel is an injection molded product of synthetic resin such as polyethylene or polypropylene. Each plate panel 6, 7, 8 ₁ , 8 ₂
have approximately the same size and shape for the lateral side walls, width side walls, and bottom wall of the box.
In particular, the plate-like panel 6 for the lateral side wall has a rectangular shape with a width and length equal to approximately equally dividing the lateral side wall of the box in the longitudinal direction of the lateral pipe 2. Similarly, the plate-like panels 8 ₁ and 8 ₂ for the widthwise side walls are rectangular with a width and length equal to approximately equally dividing the widthwise sidewall of the box in the longitudinal direction of the widthwise pipe 3. . The plate-like panel 7 for the bottom wall has a rectangular shape with a width and length equal to dividing the bottom wall of the box into approximately equal parts in the longitudinal direction of the horizontal pipe 2. Moreover, along the outer periphery of each plate-like panel, reinforcing ribs 6a, 7 are bent outward at a substantially right angle and are plate-shaped with a width of about 20 mm.
a, 8a are formed with the same height on each side.
Further, each of the plate panels 6, 7, 8 has a cylindrical connecting tube 6b ₁ , 6b ₂ , 7b, 8b through which each of the pipes 2, 3, 4 is passed along its short edge at both ends. ₁ ,
8b ₂ is integrally provided. The inner diameter of each connecting cylinder is approximately equal to the outer diameter of the pipe. The cylindrical connecting tube is integrally formed with the inner surface of each plate-like panel at a tangential position (FIG. 8).
The reinforcing ribs 6a, 7 of each plate-like panel
The heights of a and 8a are approximately the same as that of the connecting cylinder, and they are integrally molded.

Connection tubes 6a, 7a of each plate panel 6, 7, 8,
8a is formed to have the same length as the panel width when passed individually to the aggregate pipe, and is
Two types of panels 6 and 7 forming surfaces (side walls and bottom walls)
Approximately 1/1/2 of the panel width each is commonly passed through.
It is formed into two lengths. By the way, the plate-like panel 6 (Fig. 4) for forming the side wall has a vertical length of about 400 mm.
The width is about 120 mm, and the connecting tube 6b ₁ on the upper side is formed to have the same width as the panel width, and the connecting tube 6b ₂ on the lower side has a length of 1/2 of the panel width (Figs. 3 and 4).
figure).

The plate-like panel 7 (Fig. 5) for forming the bottom wall has a vertical length of about 500 mm and a width of about 120 mm, and the connecting tubes 7b at both ends are formed in a staggered arrangement with a length of 1/2 of the panel width. (Figures 3 and 5).

In other words, the two types of plate-like panels 6 and 7 mentioned above are connected to each connecting tube 6 for the lower two horizontal pipes 2, 2.
b ₂ and 7b are alternately arranged and commonly passed through (Figure 3). A series of these two types of plate-like panels 6 and 7 form a single plate-like lateral side wall and bottom wall of the transport box (FIG. 2). However, the upper connecting tube 6 in the plate-like panel 6 for the lateral side walls
b ₁ is passed individually to the horizontal pipe 2. In this way, the lateral dimensions of the transport box can be adjusted to any dimension by setting the length of the horizontal pipe 2 to the desired dimension and adjusting the number of the two types of plate panels 6 and 7 accordingly. can also be produced.

On the other hand, a plate panel 8 for the side wall in the width direction of the transport box
₁ and 8 ₂ have a rectangular shape with a length of about 500 mm and a width of about 120 mm. The form of the connecting cylinder is divided into two types. One type, as shown in FIG _. 6, is a panel 8 in which the connecting tubes _8b1 at both ends are cut off on the same side by the protruding length l of the socket at the joint 5.
It is ₁ . Another type is a panel 82, as shown in FIG _. 7, in which the connecting tubes _8b2 at both ends are formed to have the same width as the panel. This is because the vertical pipes 4 are individually passed through the connecting cylinders of these plate-like panels 8 ₁ and 8 ₂ for the widthwise side walls (FIG. 2).

As shown in FIG. 2, the method for assembling the widthwise side walls of the transport box is as follows: First, the joints 5, 5 are connected and glued to both ends of the lower width pipe 3, and then the joints 5, 5 at both ends are connected and glued. The lower ends of the vertical pipes 4, 4 are vertically connected and glued. After that, the first plate panel 8 ₁
The left and right connecting tubes 8b ₁ , _{8b 1} are passed through the vertical pipes 4 , ₄ with their notch sides facing downward. Next, the connecting tubes 8 at both ends of the second plate panel 8 ₂
b ₂ and 8b ₂ are passed through the vertical pipes 4 and 4 and stacked on the previous plate-like panel 8 ₁ . This second plate panel 8 ₂
By adjusting the number of sheets, the height of the side wall in the width direction can be manufactured to any desired height. Finally, with the notch sides of the connecting tubes 8b ₁ at both ends of the plate-shaped panel 8 ₁ facing upward, the connecting tubes 8b ₁ and 8b ₁ are passed through the vertical pipes 4 and 4, and placed on top of the previous plate-shaped panel 8 ₂ . Overlap. Next, the joints 5, 5 are connected to both ends of the upper width pipe 3, and the joints 5, 5 at both ends are connected and bonded to the upper ends of the vertical pipes 4, 4.

The widthwise sidewalls of the box thus completed are the plate-like panels 6 that form the aforementioned lateral sidewalls and bottom wall...
and 7... are connected to both ends of the horizontal pipe 2 to the corresponding sockets of the joints 5, 5, and the box is assembled.

As shown in the cross-sectional view of FIG. 8, the transport box 1 assembled in this way has plate-like panels 6 and 7, or 6 and 8, or 7 and 8 that intersect at right angles, each having a space within the space without any gaps. The inner surface of each plate-like panel is formed at a position that includes a tangent to the connecting cylinder so as to form a corner.

Second Embodiment In the case of the cubic-shaped transportation box 10 with an open top surface shown in FIG. 9, each joint 1 for assembling the frame
1 has an isosceles right triangular reinforcing rib 11a between each side wall and the socket in the same direction. For this purpose, plate panels 13, 14, 15 forming each side wall of the box
are all connected and assembled with vertical pipes 12. Therefore, the side wall plate panels 13, 14, 1
5 can be roughly divided into three types shown in FIG.

The first plate-like panel 13 for the side wall is formed symmetrically as inclined portions 13a, 13a whose left and right corners are inscribed in the reinforcing rib 11a of the joint 11, and the connecting tube 13b is formed on the side of the inclined portion 13a. The length of the socket of the joint 11 is cut away, and the opposite side is cut away by the length of the connecting cylinder of the second plate-like panel 14, which will be described later, to form a short cylindrical body with only the central portion remaining.

The second plate-like panel 14 also has an inclined portion 14a whose left and right corners are inscribed in the reinforcing rib 11a of the joint 11.
The connecting cylinder 14b is configured as a short cylindrical body corresponding to the dimension left on the non-slanted side of the connecting cylinder 13b of the first plate-like panel 13.

The third plate panel 15 has connecting tubes 1 at both ends thereof.
5b and 15b are formed to have a length 1/2 of the panel width.

In addition, the above three types of plate panels 13, 14, 15
is also formed as an injection molded product of synthetic resin such as polyethylene or polypropylene, and the outer peripheral edge thereof has reinforcing ribs 13c, 1 that stand upright outward.
4c and 15c are formed.

Next, the plate panels 18 and 19 forming the bottom wall of the transport box 10 are all connected to the lower horizontal pipes 16, 16.
(or the width pipe 17 in some cases) and is assembled. These plate-like panels 18 and 19 are roughly classified into two types.

The first plate-like panel 18 has an inclined portion 18 whose left and right corners are inscribed in the reinforcing rib 11a of the joint 11.
a, 18a, connecting cylinders 18 at both ends
b, 18b are formed into a cylindrical body which is cut out by the sloping portion 18a.

The second plate-shaped floor panel 19 is formed into a cylindrical body with connecting cylinders 19b at both ends having the same length as the width of the panel.

Therefore, the method of assembling the transport box is to first connect the lower horizontal pipe 16 and width pipe 17 of equal length with the joints 11, 11 and assemble them into a square shape. At this time, prior to assembling the side walls, the bottom wall is assembled when the lower horizontal pipe 16 and the width pipe 17 are assembled into a rectangular shape using the joint 11. To do this, first, the first plate-like panel 18 for the bottom wall is oriented so that its inclined portion 18a faces the joint 11, and its connecting tube 18b is passed through the horizontal pipe 16. Subsequently, the connecting tube 19b of the second plate-like panel 19 is passed through the rear side thereof. Depending on how many plate-like panels 19 are used, the lateral dimension of the bottom wall (width dimension when passed through the width pipe 17) can be manufactured to a desired size. Finally, the first plate-like panel 18 is connected again so that its inclined portion 18a is connected to the joint 1.
The connecting cylinder 18b is passed through the horizontal pipe 16 so as to face the connecting cylinder 18b. In this way, the connecting tubes of all the panels are connected to the two horizontal pipes 16, 16 (or the width pipe 1
7, 17) sequentially, and then the horizontal pipe 16
The assembly of the bottom wall is completed by connecting and gluing both ends to the corresponding sockets of the joint 11.

Next, assemble the side walls. To do this, first, the lower ends of the vertical pipes 12 are vertically connected to the joints 11 at the lower four corners and glued. After that, the first plate-like panel 13 for the side wall is placed in a position where the inclined part 13a faces downward, and the two horizontal pipes 16, 1 are attached.
6 (or the width pipe 17 is also acceptable), the vertical pipe 12,
Pass 12. A total of two first plate-like panels 13 are used, arranged so as to face each other in parallel in the lateral direction. Next, place the second plate-like panel 14 on top of the width pipe 17, with the inclined portion 14a facing downward, and connect the connecting tubes 14b, 14b to the vertical pipe 1.
Pass through step 2 and overlap. This second plate panel 14
Only two sheets in total are used, arranged parallel to each other in the width direction. After this, the third plate-like panel 15 is connected to the connecting cylinders 15b and 15b of the panels forming two right-angled sides.
are successively passed through the vertical pipe 12 and stacked so that two panels overlap to form one panel width. Depending on how many third plate panels 15 are used, the height of the transport box 10 can be manufactured to a desired size. Finally, the second plate-like panels 14, 14 are arranged so as to face each other in parallel in the lateral direction.
Each sheet is used with its inclined portion 14a facing upward. Further, in the width direction, a first plate panel 13,
13 facing each other in parallel, one by one
A posture in which 4a and 13a are facing upward is used. Finally, connect the upper horizontal pipe 16 and width pipe 17 to the joint 11
By assembling them into a rectangular shape in advance, and connecting and gluing the corresponding downward sockets of each joint 11 to the upper end of the vertical pipe 12, the entire assembly of the transport box is completed.

Other Examples The shape and size of the plate panel are not limited to those described above. For example, as in the plate panel 20 shown in FIG. 11, the length of the connecting tube 20a at one end is a
In this case, the connecting cylinder 20b at the other end may be formed by cutting off one side by the dimension a and cutting off the other side by an arbitrary dimension b, and forming the remaining length c. By using such a plate-like panel 20, it is possible to assemble transport boxes of even more diverse shapes and sizes.

Effects of the present invention As described above in detail along with the examples,
The assembled transport box with an open top surface according to this invention can be designed and manufactured to suit the length of the aggregate and the number of plate panels used, thereby making it possible to control the size and form of the transport box. It can be designed and manufactured as desired. However, since the plate-like panels are commonly used, there is no need to change or manufacture molds depending on the size and form of the transport box. That is, by preparing a total of three types of components, which are broadly classified into aggregate, joints, and plate-like panels, it is possible to easily and inexpensively meet the demand for transport boxes of various sizes and shapes. There are no problems with mold production or molding performance.

Of course, by preparing various types of joints and shapes of aggregates and plate-like panels, it is possible to manufacture transportation boxes with an even wider range of shapes and functions.
It can be used for household or industrial purposes.
