Description

[Detailed explanation of the invention] A. Industrial application field The present invention involves installing supports at the four corners of a flat pallet that can carry a certain amount of cargo and can be moved by a forklift or pallet truck. The present invention relates to an assembly type container comprising a top plate having four corners connected to each other at the upper end.

B. Prior Art Conventionally, as a type of container similar to a prefabricated container, as described in Japanese Utility Model Application Publication No. 158468/1983, a pallet with supporter for stacking has been used, which is a pallet with receiving rods at the four corners of a pallet stand. was removably installed vertically, and an X-shaped upper horizontal support rod was removably suspended horizontally at the upper end of each receiving rod. Also, Utsukai Showa 52-
As described in Publication No. 154859, as a "pallet with stacking supports," receiving rods are removably installed vertically at the two corners of the pallet stand, and at the upper end of each receiving rod. A connecting rod is removably suspended horizontally, and joint fittings are fixed to the left and right sides of the center of the connecting rod, and L-shaped fittings are removably attached to the other two corners of the connecting rod. There was one in which each end of the support rod was removably fitted.

C. Problems to be solved by the invention All of the "pallets equipped with stacking supports" described in the above publication have pillars attached to the four corners of the pallet that can be attached and detached. Corner metal fittings are provided in advance to receive the pillars, and the corner metal fittings are made by welding a cylindrical receiving tube into which the pillars can be inserted into the corners of the upper deck of the pallet, so the strength is insufficient. However, the props lacked stability, and there was a risk that the containers would shift when stacked several times.

Moreover, the pallet is composed of an upper deck, a lower deck, and an intermediate member, and a wide space is formed between both decks to serve as a fork insertion part, and the corner where both decks are connected to each other increases the rigidity of the pallet. This is an important point to decide, and the corner metal fittings attached to the corners are combined with both decks and integrated with the pallet, and serve to increase the rigidity of the pallet. It is necessary to be firmly attached to the

However, the above-mentioned conventional "pallets equipped with stacking supports" are all made by welding a mounting member with a U-shaped cross section to a cylindrical receiver, and sandwiching both decks between the mounting members. The member is simply fixed on one ridge line of the receiver, which poses a problem in terms of strength.

Furthermore, in order to increase the bonding force between the pallet and the corner metal fittings, they are connected by a large number of bolts and nuts, but the heads of these bolts are installed so that they protrude into the insertion part of the fork, and when the fork is inserted. In addition, it was a nuisance to screw in the large number of bolts and screws, which hindered work efficiency.

In addition, in the "Pallet with stacking supporter" described in Japanese Utility Model Application Publication No. 52-158468, the connection between the mounting pipe and the receiving rod, and the connection between the receiving rod and the fitting tube are devised. However, due to the shape of the fitting portion, the mutual contact area is small, and there is still a problem in terms of strength, which requires improvement.

As mentioned above, the "pallet equipped with stacking supports" described in the above publication is convenient for easily and simply assembling and folding the stacking supports on the pallet table, but it does not cover the important parts. There were many areas where the strength and overall rigidity of the container were lacking.

In both cases, there was no proper system for displaying the contents of the containers, and there were no drainage holes for use outdoors or in the rain, making them impractical in terms of usability and longevity. .

D. Means for Solving the Problems In view of the problems of the conventional prefabricated containers mentioned above, the present invention solves all of those shortcomings and problems, and creates an almost complete prefabricated container, that is, the strength of the corner metal fittings and the support structure. This product provides an assembly type container that has a high connection strength between top plates, etc., has excellent overall rigidity, and is easy to install, assemble and disassemble, and operate a fork. The container is assembled by erecting supports on corner metal fittings provided in the pallet, and connecting the inset pipes at the four corners of the top plate to the upper ends of the four erected supports, respectively. A patch plate was formed below the right-angled isosceles triangle-shaped substrate that was in contact with the corner of the deck along the isosceles edge of the right-angled isosceles triangle, and a drainage hole was bored at the bottom of the upper surface of the substrate. A cylindrical receiving tube is vertically disposed with its lower end circumferentially circumscribing the isosceles edge, and a connecting member having a U-shaped cross section is sandwiched between both sides of the receiving tube, and the lower side of the back side plate is shaped like an isosceles triangle. Installation with a U-shaped cross section, which is vertically installed on the side of the receiving pipe in contact with one side, and furthermore, the notched corner of the upper deck is inserted into the upper part of the back side of the connecting member and is held by a countersunk head bolt. In addition to being provided with a plate, the support column has a cup-shaped receiving part at the upper end, a hook part on the outside of the center part, and a fitting ring and a positioning protrusion on the outside of the receiving pipe insertion part at the lower end. .

E. Effect: Place the bottom plate on the bottom of the board along the isosceles edge of the right-angled isosceles triangle at the corner of the lower deck, and mount the board in contact with the corner. A receiving tube is vertically disposed with its lower end peripheral edge circumscribing the isosceles edge, and the receiving tube is held between both side plates of a connecting member having a U-shaped cross section, and the lower side of the back side plate is attached to the other side of the isosceles triangle. The corner fittings can be attached to the four corners of the flat pallet by vertically disposing the fittings in contact with the side of the receiving pipe, and by providing a mounting plate having a U-shaped cross section above the back side of the connecting member.

Insert the notched corner of the upper deck into the mounting plate, and screw in the countersunk head bolt from above the mounting plate to clamp the upper deck.

Next, fit the receiver tube insertion part of the strut into the receiver tube of the corner fitting, but at this time, position the positioning protrusion at the specified position and fit the fitting ring to the outside of the head of the receiver tube, so that the strut will fit into the hooking part. It is securely fixed to the receiving pipe in a fixed direction.

Furthermore, by connecting the fitting tubes at the four corners of the top plate to the cup-shaped receivers at the upper ends of each support, a rigid container can be easily assembled.

When disassembling the container, operate in the reverse order.

F. Embodiment An embodiment of the sectional container according to the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of an assembled container according to the present invention, and FIG. 2 is an assembled perspective view of the container.

That is, corner metal fittings 2, 2, etc. are attached to the four corners of a wooden flat pallet 1, and supports 3 made of metal pipes are inserted into the receiver pipes 23 of the corner metal fittings 2, and the supports are attached to the four corners. 3, 3, etc. are erected, and the fitting pipes 42 at the lower four corners of the top plate 4 made of a wooden frame are fitted into the cup-shaped receivers 33 at the upper ends of each column 3, respectively, and the top plate 4 is attached to each column 3. By joining them together, a container with the pallet 1 as the bottom plate can be assembled.

The wooden flat pallet 1 has a well-known shape in which a fork insertion part 14 is formed with an intermediate member 13 interposed between an upper deck 11 and a lower deck 12.
The four corners of the upper deck 12 are rounded in the shape of a right-angled isosceles triangle.

As shown in FIGS. 3a, b, and c, the corner fitting 2 includes a base plate 21 having approximately the same shape as the notched right-angled isosceles triangle of the upper deck 11, and the isosceles edge of the base plate 21 has a lower Backing plates 22, 22, which are bent at right angles to each other, are connected to each other.

Further, on the upper surface of the substrate 21, a cylindrical receiving tube 23 whose lower end circumference is circumscribed by an isosceles edge is vertically disposed, and a connecting member 24 having a U-shaped cross section is connected to the side pieces 24.
The sides of the receiver tube 23 are held between the panels 24a and 24a, and the lower end of the back plate 24b is placed against the other side of the base plate 21 so as to extend along the outside of the receiver tube 23. Furthermore, a mounting member 25 having a U-shaped cross section is attached to the upper rear surface of the back plate 24b of the connecting member 24, and is attached to both side plates 25a, 25a.
It is installed horizontally so that the
When the substrate 21 is placed with its right angle portion aligned with the corner of the lower deck, the cutout corner 15 of the upper deck 11 is sandwiched within the U-shape of the mounting member 25.

Bolt insertion holes 26, 26 are bored in the board 21, and the board 21 can be fixed to the corners of the lower deck 12 with countersunk head bolts 16 and nuts 17, and both side plates of the mounting member 25 can be fixed to the corners of the lower deck 12. 2
5a and 25a have bolt insertion holes 2 that penetrate vertically.
7, 27 and 28, 28 are bored respectively,
A bolt insertion hole 18 is formed in the upper deck 11, and the bolt insertion holes 27, 27 and 28, 28 and countersunk head bolts 19 and nuts 20 passing through the insertion hole 18 can be tightened from both sides to connect them. . (See FIG. 5) In the drawing, 29 is a water drain hole for preventing corrosion of the corner metal fitting 2, and 30 is a string hole for passing a string to hang a stored item.

The support 3 is made of a metal circular pipe, and a skirt-shaped fitting 32 is provided on the outside of the base of the receiving tube insertion portion 31 at the lower end thereof, and the receiving tube insertion portion 31 is attached to the receiving tube 23 of the corner fitting 2. When the sleeve is inserted, the skirt-like fitting ring 32 fits on the outer periphery of the receiving tube 23, and the receiving tube 23 is inserted into the long receiving tube insertion part 3.
1 and the deep fitting ring 32, the column 3 and the receiving pipe 23 are firmly connected, and swinging of the column 3 can be completely prevented.
Further, a cup-shaped receiving portion 33 is formed at the upper end of the support column 3.

The top plate 4 is a wooden square frame having the same planar size as the pallet 1, and is provided with striations 41 on the diagonal. Since the stiffness 41 increases the rigidity of the top plate 4, inexpensive wood can be used instead of steel.

As shown in FIG. 6, on the lower surface of the four corners, there is a deep insertion tube 42 that fits into the receiving part 33 of the upright pillar 3 and connects the pillar 3 and the top plate 4. The insertion tube 42 has a thick tapered base and is attached to a corner of the top plate 4 via a mounting plate 43 with screws.

In the prefabricated container configured as described above, in addition to the support 3 being firmly connected to the receiving tube 23 as described above, the support 3 and the top plate 4 are also connected to each other in the receiving part 33 at the upper end of the support 3. Since the fitting tube 42 is cup-shaped, the fitting tube 42 is deeply inserted into the column 3 and is tightly coupled, and the taper at the base is crimped to the top of the receiving part 33, so the top plate 4 is firmly attached to the column 3. This increases the rigidity of the prefabricated container.
In addition, since the receiving portion 33 is cup-shaped, the insertion operation is possible even if the top plate 4 is distorted and the center of the support column 3 and the center of the insertion tube 42 do not match, and the base of the insertion tube 42 is tapered. Since it is thick, even if the center is misaligned, if you apply force and force it in, the position will be corrected along the taper, and you can assemble it into a container without distortion.

On the other hand, the joining fittings used are provided with a backing plate 22 below the isosceles edge that sandwiches the right angle of the board 21, so that the backing plate 22 can be simply pressed from the side of the corner of the lower deck 12. The board 21 can be precisely fitted to the corner of the lower deck 12 and placed in an accurate position, and the positioning when drilling the bolt insertion hole 26 can be easily and reliably performed.

Further, the connecting member 24 has a U-shaped cross section and its bottom end is connected to the substrate 2.
In addition to being fixed to 1, both side plates 24a, 24
A and the back plate 24b embrace the receiving tube 23, and the receiving tube 2
Since the base plate 21, the receiving pipe 23, and the connecting member 24 are fixed in a line contact state in the direction of the third line of No. 3, the mutual connection between the base plate 21, the receiving tube 23, and the connecting member 24 is strong, and the strength of the corner metal fitting 2 itself is increased. Since the mounting member 25 is fixed to the back plate 24b of such a connecting member 24, the mounting strength is high. Further, the connection of the upper deck 11 to the mounting member 25 is strong because the corner portions are sandwiched from above and below by the mounting member 25 having a U-shaped cross section and tightened with bolts. Sufficient fixing force can be obtained by simply tightening bolts to the base plate 21 to connect the lower deck 12. Therefore, since the upper and lower decks can be connected by tightening a total of four bolts at each corner, the assembly work can be performed easily and easily.

A pallet in which both decks are assembled using the corner fittings 2 as described above is firmly connected and integrated, thereby increasing the rigidity of the entire pallet.

In addition, to connect the corner metal fittings 2 and the pallet, special nuts and bolts with countersunk heads as shown in the fourth figure are used to eliminate most of the protrusions, so that the forks in the pallet can be connected as shown in the fifth figure. Insert part 14
It is smooth and smooth, and there is no risk of the fork getting caught in the insertion part and becoming unable to be inserted or removed.

In the above embodiment, a four-sided pallet has been described, but the same applies to a two-sided pallet. In addition, in the corner fittings, the backing plate is bent and formed on the side of the substrate, but as long as it is formed integrally, it may be provided by welding.

Furthermore, it is possible to use not only metal pipes as supports but also wooden supports, and in the case of metal supports, for example, as shown in the first figure, there is a hanging part on the outside of the central part of the support. A hook 34 is attached to hang the display plate, and a positioning pin 35 is provided on the outside of the lower receiving tube insertion portion 31. When inserting the receiving tube insertion portion 31 into the receiving tube 23, the positioning pin 35 is attached to the receiving tube. If it is inserted into the gap 23a between the connecting member 23 and the connecting member 24 and positioned so that the display plate is latched outward, it is convenient to easily identify the stored items.
