Description

[Detailed description of the invention] (Field of industrial application) This invention is a container used for transporting cargo within a factory or to another location such as another company's factory, more specifically a container. The present invention relates to an attachment structure between a shelf board and a support such as a frame that rotatably supports the shelf board.

(Prior Art) Generally, this type of container has a plurality of shelves for placing cargo, and the shelves are configured to be tiltable with respect to the support to facilitate taking out the cargo. has been done.

The applicant has already developed such a container as shown in FIG. 9 (Japanese Utility Model Publication No. 137223/1983). That is, as shown in the figure, this container includes a plurality of shelf boards 13d each having a pair of guide pins 14d as protruding bodies protruding outward from the rear side of both sides, and rotating parts on both sides of the shelf boards 13d. In order to support the shelf board 13d movably, a large number of substantially rectangular long holes 9d having a horizontal part 10d and an inclined part 11d into which the guide pins 14d of the shelf board 13d can be slidably inserted are bored at the top and bottom of the rear side. In use, the guide pin 14d of the shelf board 13d is moved from the horizontal portion 10d of the elongated hole 9d of the support 6d to the inclined portion 1.
When the guide pin 14d is slid toward the 1d side, the guide pin 14d is inserted into the inclined portion 11d side, thereby causing the shelf board 1
3d is tilted from a horizontal state to a predetermined angle according to the inclination angle of the inclined portion 11d,
The front side of the shelf 13d flips upward, and as a result, the cargo on the shelf board 13d slides off the rear side of the shelf board 13d, making it easy to take out the cargo.

(Problem to be Solved by the Invention) However, in the container as described above, the guide pin 14 is used to prevent the shelf board 13d from accidentally coming off when the shelf board 13d slides.
Since the head portion 14e of the shelf board 14e is formed to have a diameter larger than the width of the elongated hole 9d formed in the support body 6d, the shelf board 13d cannot be removed from the support body 6d in that state. Therefore, when replacing the shelf board 13d with another shelf board, for example, in order to remove the shelf board 13d from the support body 6d, the guide pin 14d must be removed from the shelf board 13d each time. had become extremely complicated.

The present invention was developed as an improvement to the conventional containers described above in order to solve these problems.The present invention allows the shelves to be attached to and detached from the supports without removing the guide pins from the shelves. , the purpose is to very easily and smoothly replace shelf boards with a one-touch operation.

(Means for Solving the Problems) In order to achieve such an object, the present invention provides a support having a long hole formed of a horizontal part and an inclined part as described above, and a support having a long hole in the support. The above problems can be solved by improving the shape of the support and the manner in which the long holes are formed, assuming that the container has a shelf board with protrusions such as guide pins that can be inserted into the container. In order to solve this problem, the support body is connected to the front piece 6a and the side pieces 6a.
b, and a locking step portion 12 is formed on the extraction side of the horizontal portion 10 to which the protruding body can be locked, and the protruding body can be extracted. The hole 15 is connected to the elongated hole 9.
The hole is continuous with the horizontal portion 10 and extends to the side piece 6b.

(Function) And a container with such a configuration is
By sliding the shelf board 11, the protruding body moves within the horizontal part 10 and the inclined part 11 of the elongated hole 9, and the shelf board 13 becomes tiltable. When sliding the shelf board 13, Since the horizontal portion 10 is formed with the locking step portion 12 as described above, the protruding body is locked to the locking step portion 12 and the shelf board 13 is
This prevents the material from accidentally slipping out of the support.

When the shelf board 13 is to be removed from the support body, the shelf board 13 is slightly lifted to release the locked state between the locking step part 12 and the protruding body, and the shelf board 13 is pulled toward the front side. Since the above-mentioned extraction hole 15 is formed on the side piece 6b side of the support body continuously from the horizontal part 10, the protrusion can come out from the extraction hole 15 and Therefore, the shelf board 13 is removed from the support.

(Example) Hereinafter, embodiments of the present invention will be described according to an example shown in the drawings.

It is formed in a substantially V-shape with an inclined portion 11 inclined at a predetermined angle (approximately 60 degrees). Reference numeral 12 indicates a locking stepped portion formed on one end side of the horizontal portion 10. Reference numeral 15 denotes an extraction hole for extracting the guide pin 14, which is continuous with the horizontal part 10 via the locking step part 12 and has a step difference from the horizontal part 10, as shown in FIG. It is perforated up to one side piece 6b of the rear frame 6. 1
Reference numeral 7 indicates a large number of keyhole-shaped holes drilled at the top and bottom of the front frame 5, as shown in FIG.

Reference numeral 13 denotes a shelf board having a substantially rectangular shape in plan, and at the rear of the left and right sides of the shelf board 13 are guide pins 14 that can be inserted into the long holes 9 of the rear frame 6, as shown in FIG.
14 are bored outward, two each, for a total of four.

Reference numeral 18 denotes a substantially P-shaped lock bar that can be inserted into the hole 17 of the front frame 5, and a locking pin 19 is provided at the tip.

The shelf board 13 is constructed by inserting the guide pins 14 of the shelf board 13 into the long holes 9 at desired positions among a total of 18 pairs of long holes 9 of the rear frame 6, and
By inserting the lock bars 18 into the holes 17 of the front frame 5, a total of six lock bars are attached at equal intervals above and below between the frames 3 on both sides, as shown in FIG. Reference numeral 20 indicates a top plate attached between the frames 3 and above the uppermost shelf board 13. Note that this top plate 20 is also attached to the frame 3 with the same structure as the shelf board 13, but the elongated hole 9 into which the guide pin 14 of the top plate 20 is inserted has the same shape as the other elongated holes 9. The extraction hole 15 is not formed continuously in the horizontal part 10 as shown in FIG.
The upper part of one end is cut out.

As mentioned above, the bottom plate 1, the pair of frames 3,
3. A pair of side plates 8, 8, 6 shelf plates 13, top plate 2
0, an upper rod 24, and lower rods 25, 26 constitute a container 22.

Container 2 with the above configuration
2, insert the guide pin 14 of the shelf board 13 into the horizontal part 10 of the long hole 9 of the rear frame 6, and insert the lock bar 18 of the shelf board 13 into the hole part 1 of the front frame 5.
7, rotate the lock bar 18, and insert the locking pin 19 into the hole 17 of the rear frame 6.
It is used to maintain the shelf board 13 in a horizontal state by engaging the periphery of the shelf board 13, and it is used to maintain the shelf board 13 in a horizontal state. 21 is placed. The cargo placed on the shelf board 13 is transported to a desired location within the factory by the rolling motion of the casters 2, or the container 22 is loaded onto a truck or the like and transported to another destination. be.

Furthermore, when taking out the cargo placed on the shelf board 13 in this way, first rotate the lock bar 18 as shown in FIG. 4D to release the engagement state of the locking pin 19, and If the lock bar 18 is pulled out from the hole 17 as shown in (b), the locked state of the lock bar 18 will be released.

Next, after the lock state is released in this way, if you slide the shelf board 13 slightly backward, the fifth
As shown in FIG.
The shelf board 13 is tilted to the rear side according to the inclination angle of the inclined part 11, and the shelf board 1
3 flips upward, thereby allowing the cargo 20 to slide down on the shelf board 13 and to be easily taken out from the rear side of the shelf board 13.

After taking out the cargo 20 in this way, move the guide pin 14 from the inclined part 11 of the elongated hole 9 to the horizontal part 10.
When the shelf board 13 is slightly pulled toward the front side in order to move it to the side, the shelf board 13 gradually falls down in accordance with the slide of the guide pin 14, and both guide pins 14, 14 move into the horizontal part 10. When I did,
The shelf board 13 returns to its original horizontal state as shown in FIG. 5A.

In this case, since a locking step 12 is formed on one end side of the horizontal portion 10, the guide pin 14 is locked to this locking step 12, thereby preventing the shelf board 13 from being damaged. This will prevent premature withdrawal.

Furthermore, when removing the shelf board 13 from the frame 3, first lift the shelf board 13 slightly from the above state, so that the guide pin 14 of the shelf board 13 and the locking step part 12 of the elongated hole 9 are engaged with each other. is released, and when the shelf board 13 is pulled toward the front in the disengaged state, the guide pin 14 is inserted into the extraction hole formed in the side piece 6b of the rear frame 6, as shown in FIG. 5C. As a result, the shelf board 13 can be easily removed from the frame 3. Therefore, replacement of the shelf board 13 can be carried out very easily by the above-mentioned operation.

By performing the same operation on all six shelf boards 13 in total, each shelf board 13 can be freely replaced.

In this way, in the above embodiment, the guide pin 14
The shelf board 13 can be easily removed from the frame 3 by removing the guide pin 14 from the extraction hole 15 without removing it from the shelf board 13, and therefore the shelf board 13 can be replaced. Now I can do it easily and freely.

In addition, each shelf board 13 is attached to the frames 3, 3 as described above.
The six shelf boards 13 are attached to the rear frame 6 of the frame 3 at equal intervals.
However, since a much larger number of elongated holes 9, 18 in total, are drilled, the guide pins 14 of the shelf board 13 are once removed from the extraction holes 15 as described above, and the shelf board 13 is attached to the frame. Remove from 3 and remove guide pin 14
The height of the shelf board 13 can be freely changed by inserting the shelf board 13 into another long hole 9 that is not in use.
Incidentally, in the above embodiment, three times as many long holes 9 as the shelf boards 13 are formed, so one shelf board 1
3 can be adjusted in height in at least three stages, and the space between each shelf board 13 can be arbitrarily adjusted, making it possible to load a wide variety of cargo.

Further, the shelf board 13 and the top board 20 can be removed from the frame 3, and the frame 3 can be removed by removing its lower frame 4 from the bottom board 1, and the side board 8 can be removed from the frame 3. Each shelf board 1 can be removed by removing it.
3. The top plate 20, the frame 3, the bottom plate 1, and the side plates 8 can all be disassembled, which has the advantage of being able to be transported to a distant place, such as overseas, by packing in the disassembled state.

In the above embodiment, two guide pins 14 are formed on the side surface of the shelf board 13, but the number of guide pins is by no means limited to this. As shown in FIG. 6, only one elongated flat guide plate 14a may be provided protrudingly. In short, a protrusion such as a guide pin that can be inserted into the elongated hole 9 and can slide freely from the horizontal part 10 of the elongated hole 9 to the inclined part 11 side is connected to the shelf board 13.
It suffices if it is provided so as to protrude outward from the rear side surface of the.

Furthermore, the number of long holes 9 drilled in the rear frame 6 and the number of shelf boards 13 are not limited to the above embodiments. That's fine.

Furthermore, the angle of inclination of the inclined portion 11 of the elongated hole 9 is not limited to the embodiment.

Furthermore, a rear frame 6 formed by drilling a long hole 9
The shape of the support body is not limited to the substantially rectangular C-shaped cross section as in the embodiment, but may be, for example, substantially C-shaped in cross section without an inward protruding piece as shown in FIG. 8A. Alternatively, it may have a substantially L-shaped cross section as shown in FIG. In short, it has a front piece 6a in which a long hole 9 is formed and a side piece 6b in which an extraction hole 15 is formed continuously with the long hole 9, and is formed at least in a substantially L-shaped cross section. It's okay.

Further, in this embodiment, lock bars 18 are attached to both front sides of the shelf board 13, and the lock bars 18 are attached to both sides of the front surface of the shelf board 13.
Since the front frame 5 has a hole 17 into which the locking pin 19 formed at the tip of the lock bar 18 can fit, the shelf board 1
3 is connected to the frame 3 to ensure that the horizontal state is maintained, which is a desirable effect, but the attachment of the lock bar 18 and the formation of the hole 17 are by no means a condition.

Further, in this embodiment, a separate side plate 8 is incorporated and attached within the frame 3, but the frame 3
and the side plate 8 may be integrally formed. When integrally formed in this way, the elongated hole 9 will be bored in the rear part of the side plate 8. That is, the member in which the elongated hole 9 is bored is the frame 3.
It may be either the side plate 8 or the shelf plate 13.
A large number of elongated holes 9 and extraction holes 15 are provided at the top and bottom of the rear side of the frame 3, side plate 8, etc., which are capable of rotatably supporting the frame 3 and the side plate 8, and which are formed at least in a generally L-shaped cross section.
It is sufficient if the hole is drilled. Furthermore, the side plate 8 is not necessarily essential to the present invention, and the side surface of the container may be comprised only of the frame 3.

Further, like the side plates 8, the top plate 20 is not essential to the present invention.

Furthermore, as shown in FIG. 7, a cushioning material 23 such as foamed urethane may be attached to the back side of the shelf board 13. In this case, there is no gap between the cargo 21 and the upper shelf board 13, and the cargo 21 can be left unattended. This has the advantage of preventing undesirable movement.

Furthermore, in the above embodiment, the shelf board 13, the frame 3,
Since each member such as the bottom plate 1 and the top plate 18 is configured to be disassembled, the above-mentioned favorable effects have been obtained, but being configured to be disassembled is by no means a condition.

(Effects of the invention) As described above, the present invention forms a support such as a frame for supporting a shelf board at least in a substantially L-shaped cross section having a front piece and a side piece, and furthermore, the front piece Since a hole for extracting a protrusion such as a guide pin is continuously drilled in the horizontal part of the elongated hole to one side, the protrusion can be inserted into the horizontal part of the elongated hole. If the shelf board is pulled toward the front side while keeping the shelf horizontally, the protruding body will come out smoothly from the extraction hole without being stopped by the support body, and therefore, unlike the conventional method, The complicated work of removing protrusions such as guide pins from the shelf each time the shelf is removed is no longer necessary, and the shelf can be removed from the support very easily and smoothly with the protrusions still attached. This has resulted in the remarkable effect that it is possible to do.

As a result, a great effect has been achieved in that shelf boards can be replaced with each other very easily and in a short time, with just one touch operation.
