Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box pallet.

[0002]

2. Description of the Related Art Conventionally, a box pallet having a base plate and a three-dimensional frame provided in a box-like form on the base plate is known (for example, manufactured by Elector Corporation, which is handled by Nittsu Shoji Co., Ltd.). Product name "Nestener" etc.). In this box pallet, a luggage storage space that can support and store luggage on the base plate is secured inside the three-dimensional frame,
In addition, a luggage entrance is formed on the front side of the luggage storage space.

[0003] Further, since another base plate (that is, another box pallet) can be stacked on the upper end portion of the three-dimensional frame, the box pallets are simply stacked and arranged side by side. This has the advantage that a rack of a desired size can be immediately constructed at any place. On the base plate, the load can be supported via a flat-type pallet that allows transfer by a forklift or the like, or the load can be directly transferred without using such a flat-type pallet. It can also be supported.

[0004]

In the above-mentioned conventional box pallet, since the base plate and the three-dimensional frame are integrated by welding or the like, when a horizontal force is applied to the box pallet at the time of occurrence of an earthquake or the like, the base of the three-dimensional frame is exposed. In some cases, stress concentration occurs in the portion (joint portion with the base plate portion), which is likely to lead to breakage such as cracks or welding loss. In addition, since the box pallet is a single piece as a whole, transportation costs and
In some cases, storage costs when not in use (unusable loss related to the occupied floor area) and the like may rise.

[0005] Further, when the size of the load increases, the box pallet must be replaced with a large one, so that it cannot be said that the versatility of the load storage space is low. The present invention has been made in view of the above circumstances, and aims to increase the strength to the extent that it does not break even when a horizontal force is applied, to reduce costs associated with transportation and storage, and to store luggage. It is an object of the present invention to provide a box pallet capable of improving versatility in space and the like.

[0006]

In order to achieve the above object, the present invention takes the following measures. That is, the box pallet according to the present invention includes a base plate capable of supporting and storing luggage, and a three-dimensional frame provided on the base plate in a box assembly. The three-dimensional frame secures a luggage storage space on the base plate and forms a luggage entrance at least on the front side of the luggage storage space. Further, at the upper end of the three-dimensional frame, another base plate (another same type of box pallet) can be stacked.

The three-dimensional frame has a plurality of columns and an upper connection frame that connects at least upper ends of the columns with each other. A socket portion is provided which receives the lower end of each column in an externally fitted state so that the column can be supported and can be freely removed. As described above, the connecting portion between the base plate and the three-dimensional frame has a double structure including the socket portion provided on the outer peripheral portion of the base plate and the columns of the three-dimensional frame fitted into the socket portion. Section modulus of this joint (second moment of area)
Is getting bigger. In addition, the support of the three-dimensional frame is provided so as to be able to escape from the socket of the base plate (that is, the socket and the support are not fixed).

Therefore, even if a horizontal force is applied to this box pallet in the event of an earthquake or the like, stress concentration hardly occurs at the joint between the base plate and the three-dimensional frame (since both are not fixed). With respect to the stress acting on this portion, the strength exerts enough to withstand the increase in the section modulus (second moment of area). As a result, the joint between the base plate and the three-dimensional frame can be prevented from being damaged due to horizontal force at the time of an earthquake or the like. Further, since the base plate and the three-dimensional frame can be disassembled as needed, if the box pallet is disassembled during transportation or storage, the cost can be reduced.

In addition, if the base plate and the three-dimensional frame can be disassembled, it is possible to use a common base plate and select an appropriate one from three-dimensional frames having different heights.
Therefore, versatility at least in the height direction can be provided for the enlargement of the luggage storage space. In the case of a three-dimensional frame, if the upper connecting frame is configured to be disassembled in the depth direction and / or the frontage direction, there is a greater possibility that the depth interval and the frontage interval of the support columns may be made different as necessary.

[0010] In this case, versatility in the depth direction and the frontage direction can be provided to some extent with respect to the enlargement of the luggage storage space. In the three-dimensional frame, the support members on both sides in the frontage direction can be provided with a shelf member or a shelf forming member for allowing a baggage to be passed in the frontage direction. Thus, small luggage, loose luggage, and the like can be stored, and waste space can be prevented from being generated in the luggage storage space. That is, the storage capacity can be increased.

The shelf forming member has a structure in which a plurality of locking holes are provided in the vertical direction with respect to the upright surface of the column, and an appropriate locking hole is selected from these and locked. As a result, the support height can be freely changed, thereby further improving the convenience. On the other hand, the box pallet according to the present invention may be a box pallet having a base frame capable of supporting and storing luggage, and having a leg frame provided in a box assembly shape below the base plate.

The leg frame secures a luggage storage space equivalent to that of the upper part of the base plate at the lower part of the base plate, and forms a luggage entrance at least on the front side of the luggage storage space. At the lower end of the leg frame, it can be stacked on another base plate (another same type of box pallet). In the case of this box pallet, the leg frame has a plurality of columns and a lower connection frame that connects at least lower ends of the columns. Further, a socket portion is provided on the outer peripheral portion of the base plate so as to be supported by being fitted over the upper end portion of each of the pillars in the leg frame so as to be able to escape and to be able to escape.

[0013] In the case of a box pallet having such a structure, the depth of each column and / or
Alternatively, the frontage interval can be changed, the shelf forming member can be supported, and the supporting height of the shelf forming member can be changed freely.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 7 show a first embodiment of a box pallet 1 according to the present invention. 1 shows the simplest assembled state of the box pallet 1, and FIG. 2 shows the box pallet 1 with the shelf forming member 2 added thereto. FIG. 3 shows the box pallet 1 disassembled into pieces. As shown in FIG. 7, the box pallet 1 is capable of immediately constructing a rack 3 of a desired scale at an arbitrary place simply by stacking a plurality of similar ones and arranging them side by side. Naturally, it can be used not only for such combined use but also for stocking and moving luggage as a single use.

The box pallet 1 has a base plate 5 and a three-dimensional frame 6 provided on the base plate 5 in a box assembly. The base plate 5 is a place where support and storage of luggage (not shown) are enabled, and a plate body 8 assembled into a lattice board shape by using a strip material such as a square pipe, and a plurality of outer peripheral portions of the plate body 8 (in the example shown in the figure). (In four places), and has a socket portion 9 coupled in a state where the longitudinal direction is directed in the vertical direction. The assembly of the board 8 and the connection between the board 8 and each socket portion 9 are performed by welding, riveting, bolting, or the like.

Each socket portion 9 is formed as having a hollow structure by using a square pipe or the like, so that a support column 18 of the three-dimensional frame 6 described later can be fitted therein. The sockets 9 are connected to each other so as to protrude below and above the board 8. This is to ensure a predetermined length in the hollow portion of the socket portion 9, which leads to stabilizing the support state of the three-dimensional frame 6 and providing strong support strength. In particular, the downward projection serves to secure a fork insertion space in a forklift or the like.

As shown in FIG. 4, the arrangement of the socket portions 9 is divided and arranged at the left and right ends of the front edge 8a (ie, outside the front edge 8a) near the front of the board 8 (the lower side in FIG. 4). In the rear part of the board body 8 (upper side in FIG. 4), the board 8 is distributed near both right and left ends along the rear edge 8b (that is, inside the rear edge 8b). With such an arrangement, a frontage is secured on the front side of the panel 8, and a fall of luggage can be suppressed on the back side of the panel 8.

Each socket portion 9 is provided with a stopper piece 10 projecting inward from the hollow portion at an appropriate level or lower end which is not too high in the hollow portion.
The stopper piece 10 is a part that supports the column 18 of the three-dimensional frame 6. Right and left end portions of the right side 8a of the board body 8,
Reinforcing plates 12 are attached to the left and right ends of the rear edge 8b of the board 8 so as to be in contact with the sockets 9, respectively. The front and rear reinforcing plates 12
Notch-shaped (triangular in the illustrated example) engaging portions 1 arranged in a manner matching each other in a pair with each other.
3 are provided.

On the other hand, the three-dimensional frame 6 includes a plurality of columns 18,
It has an upper connection frame 19 that connects at least the upper ends of the columns 18. Needless to say, the number and arrangement of the columns 18 match the arrangement of the sockets 9 on the base plate 5 described above, and the thickness and cross-sectional shape of the columns 18 fit into the hollow portions of the sockets 9. It is formed so that it can be inserted, does not cause large backlash, and can be relatively easily escaped.
In the first embodiment, a 50 mm square pipe having necessary and sufficient strength is selected as the column 18.
Based on this, a 57 mm square pipe (so that the material thickness of the square pipe for the socket 9 is 3.2
mm).

Each pillar 18 is provided with a plurality of engagement holes 20 at predetermined intervals in the up-down direction on an upright surface facing the left-right direction. This engagement hole 20 will be described later. The upper connection frame 19 is located closer to the back of the base plate 5 (the rear edge 8b of the board 8).
And a support bar 1 connected to the front of the base plate 5 (the front edge 8a of the board 8).
8 has a side bar 23 for connecting the column 8 and the column 18 disposed directly behind the center bar 8, and a center bar 24 for connecting the left and right side bars 23 to each other. The number of the central bars 24 may be only one, or a plurality (two in the illustrated example) may be provided before and after.

The rear bar 22, the side bar 23, and the center bar 2
4 are not fixed to each other so that connection and separation can be freely performed as needed. However, rear part 2
Numeral 2 is fixed between the upper ends of the struts 18 on both sides arranged on the back side of the base plate 5 (the rear edge 8b of the board body 8), so that the whole of them has a torii shape. Pier 23
Indicates that its front end is close to the front of the base plate 5 (the front edge 8 of the
It is fixed to the upper end of one of the columns 18 arranged in a), so that the column 18 has a hook shape as a whole. Only the center bar 24 is formed as a single piece.

It should be noted that the rear end of the side bar 23 is
Attachments 27 that can be fitted from above are attached to the top 2, and attachments 28 that can be fitted to the side bars 23 from above are provided at both ends of the center bar 24.
Is attached. An angle member is used for the side bar 23, and the side bar 23 is fixed to the column 18 in a prone manner so that the cross section has a mountain shape. And the left and right side bars 23
When they are connected to each other by the center bar 24 (when they are held at a predetermined interval), these side bars 23 are held in a positional relationship matching the right and left engaging portions 13 provided on the base plate 5. It has become something.

That is, the upper connecting frame 19 is
When the box pallet 1 is composed of the three-dimensional frame 6 and the three-dimensional frame 6 assembled on the base plate 5 at the same time (actually, these operations are not divided for each component. The side bars 23 and the engaging portions 13 are, as shown in FIG.
When the box pallets 1 are stacked one on another, they are engaged with each other to exert the effects of positioning and preventing rattling. With the base plate 5 and the three-dimensional frame 6 described above, the simplest assembled state (the state of FIG. 1) as the box pallet 1 can be obtained.

According to the box pallet 1, the base plate 5
Above, a luggage storage space 30 is secured inside the three-dimensional frame 6, and the luggage storage space 3
0 has a luggage doorway 31 formed on the front side. Therefore, the luggage can be put in and out of the luggage storage space 30 through the luggage entrance 31. At this time, the luggage may be directly supported as it is, or may be supported on a flat-type pallet (not shown) which can be transferred by a forklift or the like. Further, in the box pallet 1, the columns 18 of the three-dimensional frame 6 are connected to the sockets 9 of the base plate 5 by external fitting. A double structure with 18 is obtained. Therefore, the section modulus (second moment of area) of the connection portion increases, and a sufficient strength against horizontal force can be obtained.

Moreover, since the socket portion 9 and the support column 18 are not fixed, a small amount of horizontal force is included, but asobi is included. Therefore, excessive stress concentration due to the horizontal force is caused in the joint at first. What happens is itself avoided. When the box pallet 1 is transported or stored when not in use,
The three-dimensional frame 6 is separated from the base plate 5, and the three-dimensional frame 6 itself is disassembled into individual columns 18.
Can be disassembled into a rear bar 22, a side bar 23 and a center bar 24, so that a very compact form can be obtained. Therefore, not only the subsequent handling becomes easy, but also the cost can be reduced in various aspects.

Such disassembly can be easily performed, and the assembling from the disassembled state to the original box pallet 1 can be performed in a predetermined arrangement with respect to the socket portion 9 provided on the base plate 5.
8 is fitted, and the columns 18 are connected to each other (the upper connecting frame 19 is assembled).
In this box pallet 1, as shown in FIG. 2, the shelf forming member 2 is attached to an appropriate height in the three-dimensional frame 6, and the shelf member 35 or luggage is passed over the shelf forming member 2. Can be.

The shelf forming member 2 includes, for example, a beam type as shown on the upper side in FIG. 2 and an angle type as shown on the lower side in FIG. The beam-type shelf forming member 2 is formed of a suitable member such as a square pipe or the like, and can be said to be a structure suitable for increasing load-bearing strength. In addition, the angle type shelf forming member 2 literally uses an angle material in an L-shaped arrangement in an opposed manner, and can be said to be a structure suitable for particularly considering the positioning in the left-right direction and the prevention of slippage. Any type of shelf forming member 2
As shown in FIG. 6, both ends in the longitudinal direction engage with engagement holes 20 provided in the support columns 18 of the three-dimensional frame 6.
A detachable hook 36 is provided.

Although not shown, as a structure for engaging the engaging hole 20 with the engaging hook 36, a downward load is applied to the engaging hook 36 side (that is, the shelf forming member 2 side). It is preferable to adopt a structure in which the locking force is increased by the wedge effect as the force increases. Note that the shelf member 35 held by the shelf forming member 2 is not limited at all, and includes a sheet metal board, a grid or net extending inward of a frame, wooden, resin, or A metal plate or the like may be employed.

As shown in FIG. 2, when the shelf member 35 has a size that is approximately half the depth of the three-dimensional frame 6,
If necessary, only one shelf member 35 can be used, so that it can be perfectly adapted to the shape and amount of luggage to be stored, and unnecessary extras in the box pallet 1 can be made. It can also avoid wasting space. Further, when the luggage is directly held by the shelf forming member 2, it is necessary that the luggage has a size equal to or larger than the span of the left and right shelf forming members 2 and has a strength without bending. However, this is not the case when the luggage is placed on a flat-type pallet (not shown) that can be transferred by a forklift or the like and the flat-type pallet is held by the shelf forming member 2. .

FIGS. 8 to 11 show a second embodiment of the box pallet 1 according to the present invention. Figure 8 of these
9 shows the simplest assembled state of the box pallet 1. FIG. 9 shows the box pallet 1 with the shelf forming member 2 added thereto. FIG. 10 shows a state where the box pallet 1 is disassembled into pieces. The box pallet 1 of the second embodiment has a base plate 5 and a leg frame 40 provided in a box-like shape below the base plate 5. That is, it can be said that the box pallet 1 of the second embodiment is the same as the first embodiment described above, except that the vertical positional relationship between the underframe 5 and the three-dimensional frame 6 is reversed.

Therefore, the main function of the leg frame 40 is to secure a luggage storage space 30 equal to the upper part of the base plate 5 at the lower part of the base plate 5 and at least to the front side of the luggage storage space 30 at the front side. That is, the luggage entrance 31 is formed. The leg frame 40 has a plurality of columns 18 and a lower connection frame 42 that connects at least lower ends of the columns 18. A socket portion 9 provided on an outer peripheral portion of the base plate 5 is supported on the upper end portion of each of the columns 18 by covering the socket portion 9 with an outer fitting shape, and can be freely removed.

The lower connecting frame 42 includes a rear bar 44 for connecting the columns 18 disposed on the back of the base plate 5 (the rear edge 8b of the board 8), and a front side of the base plate 5 (for the board 8). Regular edge 8
The strut 18 arranged in a) and the strut 1 arranged immediately behind the strut 18
8 and a side crosspiece 45 for connecting the second rail 8 to the second rail 8. The rear bar 44 and the side bar 45 are not fixed to each other so that they can be freely connected and separated as needed. However, the rear bar 44 is fixed between the lower end portions of the pillars 18 on both sides disposed on the back side of the base plate 5 (the rear edge 8b of the board body 8), and the entirety thereof has an inverted torii shape. The side bar 45 has a front end, which is located on the front side of the base plate 5 (the front edge 8a of the board 8).
8 is fixed to the lower end portion, so that the hook 8 has a hook shape as a whole.

It should be noted that the rear end of the side bar 45 is
An attachment 47 that can be fitted from below (in a scoop-up shape) is attached to 4. As shown in FIG. 11, the side bar 45 is provided with a combined strip material in which an angle material 45 a is laid down so that its cross section has a mountain shape and a solid round bar material 45 b is welded in parallel at the apex thereof. Used. The triangular space formed inside the angle member 45a is used as the engaging portion 50. On the other hand, the base plate 5 is provided with an engagement ridge 51 whose longitudinal direction is directed to the front-rear direction on both the upper surface of the left side and the upper surface of the right side of the board 8. The left and right engaging projections 51 are formed by fixing the angle member to the board 8 in a prone shape so that the cross section thereof has a mountain shape.

The engaging portion 50 and the engaging ridge 51
This means that when the left and right side bars 45 are held at a predetermined interval, the left-right interval of the engaging portion 50 and the left-right interval 45 of the engaging ridge 51 are held in a positional relationship that matches each other. I have. That is, when the lower connecting frame 42 is assembled with the column 18 to form the leg frame 40, and at the same time, the leg frame 40 is assembled to the lower portion of the base plate 5 to form the box pallet 1 as a whole (actually, The work is not performed separately for each component, but is performed in a unified manner.) When the box pallets 1 are stacked on top of each other, the engaging portions 50 and the engaging ridges 51 engage with each other to achieve positioning and positioning. This has the effect of preventing rattling.

In this way, the lower end of the leg frame 40 can be stacked on another base plate 5 (box pallet 1 of the same kind). The other details of the structure, usage, operation, effects, various changes, and the like are substantially the same as those in the first embodiment, and a detailed description thereof will be omitted. The present invention is not limited to the above embodiments, and can be appropriately changed according to the embodiments.

[0036]

As is apparent from the above description, the box pallet according to the present invention is provided with a socket portion on the base plate side, and supports the lower ends of the respective columns in the three-dimensional frame in an externally fitting manner.
In addition, since it is possible to escape, stress concentration hardly occurs at the connecting portion between the base plate and the three-dimensional frame, and at this portion, the strength is increased due to an increase in section modulus (second moment of area). Therefore, it is possible to prevent the joint portion from being damaged due to a horizontal force at the time of an earthquake or the like.

Further, since the base plate and the three-dimensional frame can be disassembled, the cost can be reduced during transportation and storage, and when the luggage storage space is enlarged, the height, depth, and frontage directions can be reduced. Versatility can be achieved. Further, the box pallet according to the present invention is provided with a socket portion on the base plate side, and can be supported by being fitted over the upper end portion of each of the columns in the leg frame in an external fitting manner, and is allowed to escape. Stress concentration hardly occurs at the joint with the leg frame, and in this portion, the strength is increased with an increase in the section modulus (second moment of area). Therefore, it is possible to prevent the joint portion from being damaged due to a horizontal force at the time of an earthquake or the like.

Also, since the base plate and the leg frame can be disassembled,
The cost can be reduced during transportation and storage, and when the luggage storage space is enlarged, versatility in the height direction, depth direction, and frontage direction can be achieved.
