Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a structure in which the pallets are provided with fences at least at both the front and back ends to prevent the cargo from collapsing, and the supports are attached in a fallable manner to store the fence supports. .

[Conventional technology]

Conventionally, this type of pallet is equipped with fences 2, 2 consisting of a pair of left and right supports 3, 3 and a horizontal bar 4 between them, at both the front and rear ends of the pallet body 1, as shown in Fig. 5. Long cargo a is mainly loaded between the fences 2 and 2.

Regarding the installation of the supports, a support piece 5 is erected on the pallet body 1, and the support pieces 3 are pivotally supported on it using pins 6 so as to be able to fall inward, and the horizontal beams 4 are attached to the supports 3, 3.
It was possible to remove it from. Therefore, when the fence 2 is unnecessary or when the load a is to be unloaded, both the supports 3, 3 are folded inward as shown by the two-dot chain line.

The support piece 5 is formed into a U-shaped cross section so as to stably hold the support column 3, and has both front and rear walls 5a,
The pin 6 was installed on the 5b.

[The problem that the idea attempts to solve]

According to the conventional pallet as described above, the left and right columns 3, 3 can be tilted inward, and the support pieces have a U-shaped cross section, so the stability of the columns is good. Of the double-sided walls 5a and 5b, since the load a is supported and hangs on the upper end of the rear wall 5b,
There was a problem that it was inconvenient for loading cargo.

In addition, since the height of the pins 6, 6, which are the center of the fall of the pillar, was the same for the left and right pillars 3, 3, when the pillar fell, the other pillar 3 hung on top of one pillar 3 at an angle. Because the tip protrudes upwards, the column does not fit well, and even if you knock down the column when lowering the load, it will not only get caught on it, but also cause the load to come in contact with the tip of the column. There were also cases of damage.

Also, due to the shape of the support piece, if there is no horizontal bar,
Since the posts tend to fall naturally inward, it is inconvenient for assembling the fence, especially for attaching and removing horizontal beams.

In view of the above-mentioned circumstances, this invention allows the pillar to be stably held in an erect state even though there is no support piece surrounding it to hold it, and also allows the pillar to stand alone. The object of the present invention is to provide a structure for mounting columns on a pallet with a fence, which makes it easy to assemble and disassemble the fence because it does not easily fall in any direction, and allows for a good fit when both columns are collapsed. It is.

[Means to solve the problem]

The structure of this invention to achieve the above object is that in a pallet with a fence in which a pair of left and right columns constituting the fence are formed in a rectangular tube shape, the base material for receiving the columns is formed in a rectangular tube shape with the same cross section. Each pillar is connected to the base material by a hinge so that it can be tilted inward to face each other, and a core block with a knob, which is partially dropped into the base material below, is fitted to the lower end of the pillar, and the lower end of the pillar is The gist is that a slot is provided on the outer surface of the core block to guide a knob so that the core block can be pulled up from the base material.

[Effect]

According to the above structure, when the column is in an upright state, the core block falls into the base material below due to its own weight, and is in a locked state where it is fitted to both the column and the base material. The pillar is square to the
In other words, it remains upright and cannot fall in any direction. Therefore, in this invention, horizontal beams are not necessarily required for the fence.

When the knob is lifted, the core block is lifted from the base material and the locked state is released, allowing the column to fall over. Furthermore, when the pillar is reversed and pulled up, the core block is dropped into the base material by its own weight, and is automatically locked in the upright position.

〔Example〕

Next, an embodiment of this invention will be described based on the drawings.

Figures 1 to 4 show one embodiment, in which a pallet P with rails is provided with rails 12, 12 only at the front and back ends of the pallet body 10 for loading long cargo to prevent the cargo from collapsing. However, depending on the type of cargo, they may also be provided on both the left and right ends.

The pallet body 10 has a pair of left and right fork guides 13, 1 into which forks of a forklift are inserted.
3 as the main body, and a pair of right and left support plates 14a, 14b are welded and attached to fork guides 13, 13 at both front and rear ends, respectively.

The fence 12 includes a pair of left and right columns 20a, 20b, a horizontal beam 21 installed between them, and columns 20a, 2.
Base materials 22a, 22b that receive 0b, struts 20a,
It consists of core blocks 23, 23, etc. inside 20b.

The support trays 14a and 14b have a base material 22 in the center.
It has a hole 24 into which parts a and 22b fit,
The base materials 22a and 22b are fixed to the punched holes 24, and a recess 25 into which the base materials 22a and 22b are not fitted is provided at the lower end of the punched hole 24.

Left and right struts 20a, 20b and base materials 22a, 2
2b is made by cutting the same regular square cylindrical member, and by connecting both with a hinge 27, it is attached to the base materials 22a and 22b, respectively, so that both supports 20a and 20b can fall inward. I support it.

Of the left and right base materials 22a and 22b, the left base material 22a projects from the upper surface of the support tray 14a to a height approximately equal to the width of the support support 20a, while the right base material 22b has a hinge 27. Extraction hole 24 along with a piece of
The top surface of the base material 22b is flush with the top surface of the support tray 14b, and the hinge 28b is aligned with the top surface.

The core blocks 23, 23 are each supported by a support 20.
It is formed into a prismatic shape that fits both the base materials 22a and 22b, and has a knob 31 protruding from the center of the front surface, and a screw 32 at the end of the hinge 27 on one side. A groove 33 is formed to prevent contact.

The pillars 20a, 20b are provided with a slot 30 in the front wall at the lower end thereof, through which the knob 31 of the core block 23 can be inserted.
Slot holes 30, 30 are formed vertically so that the lower ends of the core blocks 23 can be pulled up from the base materials 22a, 22b to the supports 20a, 20b.

The horizontal beam 21 has connecting pieces 36, 36 projecting from both ends thereof to fit into the upper ends of the columns 20a, 20b.

Also, on the upper surface of the pallet body 10, there is a left support 2.
A pillow 29 for receiving the right support column 20b is fixed near 0a.

In the above-mentioned pallet P with a fence, as shown in FIGS. 1 and 2, when the fence 12 is assembled, the core block 23 lowers under its own weight and its lower end also fits into the base materials 22a and 22b. Because there are
By this core block 23, the base materials 22a, 22b
Since the columns 20a and 20b are supported so as not to fall in either direction, both columns 20
Horizontal beams 21 are installed on a and 20b.

However, without using the horizontal beam 21, these two supports 2
It is also possible to receive cargo only with 0a and 20b standing up.

When knocking down both supports 20a and 20b,
1 and then pull up the core block 23 from the base materials 22a, 22b while hooking your finger on the knob 31, it will fall down for the first time, so after removing the horizontal bar 21, the pillars 20a, 20b will fall down naturally. There are no such inconveniences.

Both columns 20a and 20b fall around hinges 28a and 28b of the hinge 27, but since the hinge 28b of the lower base material 22b is flush with the upper surface of the pallet body 10, that column When 20b is brought down first, it falls down with the thickness of the hinge 27 raised on the upper surface of the pallet main body 10.
The tip is received by the pillow 29, so that it lies down on the pallet body 10 in a substantially horizontal state.

In addition, in this state, the hinge 28a of the hinge 27 on the side of the high base material 22a is in a position substantially flush with the top surface of the down support column 20b. It becomes a horizontal parallel state.

On the lower surface of the pallet main body 10, each support column 20a,
Recesses 2 that can be fitted into each bottom of 20b
5, 25, when the horizontal beam 21 is not used, the support 20a,
By fitting the upper end of 20b, the pallet P
The pallets can be stacked on top of each other, and even in this case, the supports 20a and 20b independently maintain the upright state, making it easy to stack the pallets.

[Effect of idea]

As explained above, according to this invention, even though there is no support piece surrounding the column to hold it, the column can be stably maintained in an upright state, so when loading cargo, There is no inconvenience such as the cargo being supported by the support piece and getting caught, making it easier to load the cargo. In addition, when the prop is erected, the core block falls into the base material under its own weight and is locked to prevent the prop from falling.When the prop is toppled down, the lock is released by simply lifting the knob. Since there is no fear that it will naturally fall inward, it has the excellent effect of allowing the columns to be assembled and disassembled in a step-by-step and efficient manner.

Furthermore, by making the heights of the left and right base materials different, it is possible to improve the fit when both supports are folded down.
