[0003]

[Problems to be solved by the device]

 The former simple pallet with a door has a structure that allows stacking multiple items, which is convenient because you can open and close the doors to load and unload items when stacking, but for example, when transporting only pallets, such as when returning empty pallets. It takes up as much space as, and there is a limit to the number of pallets that can be transported. Therefore, even if the latter foldable structure is used, the foldable type has a structure in which the lower end of the side plate is folded inward as a support shaft as described above, so that the upper end is a support shaft and the lower end is flipped up as described above. Cannot be used in combination with body storage structure.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention is intended to improve the transportation efficiency and workability of the pallet itself, even if it is a simple pallet that can open the door body, and its structure is the fork insertion part. The rectangular bottom frame and the two opposite sides of the bottom frame are integrated with the upper part of the column whose base ends are fixed to the corners, and the lower edge serves as a fulcrum to support the upper part of the column. Together with the first and second side plates that can be collapsed inward, and the other two opposite sides of the bottom frame, the lower both sides are pivotally attached to the base end of the column, and the lower edge is a fulcrum to the inside. The third and fourth side plates are provided so as to be able to fall down, the support mechanism that supports the upper end of the support column above the base end portion in a disciplined state, and the upper pillars of the third and fourth side plates are vertically supported. In a foldable simple pallet having a locking mechanism for stopping, And at least one of the fourth side plates is set on the door, and pivot shafts are provided on both sides of the lower edge of the door, and the pivot shafts are provided on the base ends of the columns on both sides corresponding to the pivot shafts.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is a square in which columns 3 to 6 are erected at four corners of a rectangular bottom frame 2 having a fork insertion port 2a at the bottom, and side plates 7 to 10 are provided between the columns to open the upper surface. The box-shaped simple pallet has a structure in which the rear side plate 8 is folded inward with the lower end 81 as a fulcrum, and details thereof are shown in FIG. However, since both sides of the side plate 8 have the same structure, only one side will be described. In the figure, the pins 82 projecting from both ends of the side plate 8 are inserted into the shaft stoppers 46 provided in the frame body 42 at the lower part of the support column 4, and when the upper end 83 is free, the side plate 8 uses the pins 82 as a spindle. It becomes rotatable. Further, the upper end 83 is inserted with the fixed locking ring 84 into the locking hole 44 of the locking metal fitting 43 provided in the raising and lowering portion 41 of the column 4, and is vertically moved to the locking metal fitting 43 as indicated by the two-dot chain line. By inserting the end portion 45a of the slidably provided hook 45 into the hook ring 84, the hook 45 can be fixed to the hook fitting 43. To make the upper end 83 free, the hook 45 is lifted upward, and the latching ring 84 separates from the latching metal 43. Further, each of the columns 3 to 6 has a structure capable of undulating in one direction. Explaining the column 3 in FIG. 2, the column 3 has a rectifying portion 31 which is a square column steel pipe and a frame having a U-shaped cross section. In a divided structure with the body 32, the frame body 32 is integrally fixed to the bottom frame 2, and the raising and lowering portion 31 is attached to the frame body 32 by the pins 34 penetrating the long holes 33 provided at both lower ends thereof. It is supported. Further, elliptical projections 35, 35 are provided above the elongated holes 33, 33 in the erected portion 31, respectively. The protrusions 35, 35 of the frame body 32 in the erected state of the erected portion 31. It is designed to fit into U-shaped notches 36, 36 provided at the upper end. Therefore, when the pillar 3 is to be tilted, if the tilting portion 31 is slightly lifted to separate the protrusions 35 and 35 from the notches 36 and 36 on the side of the frame 32, the pin 34 serves as a fulcrum. Can be laid inward, and the erected portion 31 is horizontally supported by the stopper 37 provided inside the frame 32 in the laid state. Further, since the side plates 10 and 9 are fixed between the upright portions 31 and 41 and between the upright portions 51 and 61 of the columns 3 to 6, respectively, the upright portions 31 and 41 and the side plates 10 and the upright portions 51 and 61 are fixed. The side plate 9 and the side plate 9 can each fall together.

Next, the flip-up and folding structure of the side plate 7 that serves as the door of the simple pallet will be described. Since the left and right side plates 7 have the same structure, only the right side will be described. As shown in FIG. 2, inverted L-shaped hooks 72 are provided on both sides of the upper end 71 toward the inside. The hooks 72 are slide rails provided inside the upper ends of the adjacent side plates 10 of the side plates 7 in the assembled state. It is hooked on the front end 12 of 11. Further, handle-shaped handle guides 73 are provided at both outer ends of the side plate 7 at the substantially middle portion thereof, and the bent end portions 74b of the flip-up handles 74 are slidably inserted into the handle guides 73 so that In the assembled state of the lifting handle 74, the bent end portion 74b is at the lowest position of the handle guide 73 as shown in the figure, and the lifting handle 74 is in the hanging state. However, when the flipping handle 74 is flipped up from the front side, the upper end 71 of the side plate 7 is lifted. The handle portion 74a can be hung on the top. Further, retaining metal fittings 78 are fixed to both end portions of the flip-up handle 74 where the handle guides 73 are inserted, and the retaining metal fittings 78 are guided by the guide cylinders 75 at both ends of the side plate 7 so that the flip-up handle 74 In the suspended state, a stopper rod 77 that projects from the lower end 76 of the side plate 7 and contacts the bottom frame 2 is integrally attached. Further, pins 79 project from both sides of the lower end 76 of the side plate 7. The pins 79 are provided so as to surround the opening side of the lower part of the frame 32, and are formed on the pivotal plate 38 having the stopper 37. It is inserted in the lowest position of the character groove 38a, respectively. Incidentally, 39 is a stop plate which is outside the side plate 7 and is integrally attached to the frame body 32.

In the simple pallet configured as described above, when the side plate 7 is first flipped up and stored, when the flip-up handle 74 is first lifted upward from the front, the bent end portion 74 b slides in the handle guide 73. It moves and moves upward, and the stopper bar 77 moves upward together with the retaining metal fitting 78. Then, the side plate 7 in the suspended state is lifted on the slide rail 11 and the lower end 76 is pulled toward you as the hook 72 is placed on the front end portion 12, and the pins 79 on both sides of the lower end 76 are pivoted as shown in FIG. After passing through the L-shaped groove 38a of the shaft 38 and away from the pivot plate 38, the lower end 76 can get over the stop plate 39. Then, when the hook 72 is again hooked to the front end portion 12 and the flip-up handle 74 is placed on the upper end 71, the side plate 7 is hung by only the upper hook 72, and the lower end 76 becomes free. After that, as shown in FIG. 4, the lower end 76 is lifted as it is from the front to a horizontal state, and both ends of the side plate 7 are placed on the slide rails 11 and pushed in. It is supported horizontally and the front of the simple pallet is open. To fold it from the assembled state shown in FIG. 1, with the flip-up handle 74 hanging downward, lift the side plate 7 to unlock the hook 72 from the slide rail front end 12, and then pull the upper end 71 toward you. For example, as shown in FIG. 5, the side plate 7 is free from the upper end 71 with the pins 79 on both sides supported by the pivot plate 38 as fulcrums, so that the side plate 7 can be laid inward as it is as shown in FIG. When the flip-up handle 74 is at the lower position, the stopper rod 77 projects downward from the lower end 76. Therefore, when the side plate 7 is lifted to free the upper end 71 as shown in FIG. The pin 79 is prevented from coming into contact with the stopper plate 39 and separating from the L-shaped groove 38a, and there is no risk that the lower end 76 will fly out to the front. Further, since the rail guide 13 is horizontally attached above the slide rail 11 with a space slightly larger than the height of the vertical portion of the hook 72, the rail guides 13 are horizontally attached between the raising and lowering portions 31 and 41 and 51 and 61. If the handle 74a of the flip-up handle is placed on the upper end 71 while the side plate 7 is hooked on the hook 12 as shown in FIGS. 1 and 4, the hook 72 is prevented from coming off due to interference with the rail guide 13. This prevents the hook 72 from coming off the hook 12 due to vibration or the like. As described above, in the simple pallet of the present embodiment, after the side plates 7 and 8 are folded inward, the upright portions 31 and 41 of the columns 3 to 6 and the side plate 10, and the upright portions 51 and 61 and the side plate 9 are folded. When the items are folded as described above, the items can be completely folded as shown in FIG. 8. Therefore, the side plates 7 serving as the doors can be optionally opened even in a stacked state during the transportation of goods, and in the transportation of only pallets. It can be folded so that it is not bulky and can carry many at once. If necessary, the side plate 7 can be removed from the simple pallet 1 by releasing the hooking of the upper end of the side plate 7 and the pivotal attachment of the lower end.

In the above embodiment, only the front side plate 7 is flipped up for storage and folding, but the rear side plate 8 may have a similar structure, and a pair of front and rear side plates may have the above-mentioned combined structure.

[0010]

[Effect of device]

 As described above, according to the present invention, since the side plates can be opened in the assembled state and can be completely folded, a large number of sheets can be stacked when the pallets themselves are transported, and the pallets can be stacked. Therefore, transportation efficiency and workability are improved.
