(Configuration of transport pallet)
1A to 1C are perspective views of a returnable transport pallet 100 to which a height extending member 140 according to an embodiment of the present invention is attached. The transport pallet 100 is integrated with the floor panel 130 by vertically connecting two front and rear toe panels 110 and two right and left side panels 120 to each other after vertically standing on four sides of the rectangular floor panel 130. It has become so. The floor panel 130 is rectangular in the illustrated example, but may be square. In the following description, the toe panel 110 and the side panel 120 may be collectively referred to as a “side wall panel” for convenience.

The floor panel 130 is formed with two rectangular holes 132 on the left and right sides for inserting the two claws of the forklift. Depending on the shape (for example, square) of the floor panel 130, the forklift can be inserted in four directions by forming the hole 132 in the four directions of the floor panel 130.

In the example of FIGS. 1A to 1C, the hook panel 110 and the side panel 120 are configured by combining steel materials such as square pipes and shaped steel in a lattice shape. The lattice shape is an example, and the configuration of the toe panel 110 and the side panel 120 is arbitrary. For example, the toe panel 110 and the side panel 120 can be configured by additionally combining diagonal materials. Moreover, you may make it the structure which has arrange | positioned the corrugated steel plate inside the rectangular frame.

The transport pallet 100 is configured to be stackable as shown in FIG. For the stacking, an upward hemispherical convex portion 21 is formed on the upper corner metal fitting 20 fixed to the upper end portion of the column member 121 of the side panel 120, and corresponding to the convex portion 21, as shown in FIG. Circular holes 131 are formed in the bottom surface of the four corners of the floor panel 130. When the transport pallets 100 are stacked, the hemispherical convex portions 21 of the lower transport pallet 100 are fitted into the circular holes 131 of the floor panel 130 of the upper transport pallet 100, thereby preventing the pallets 100 from being displaced from each other. It is like that.

(Height extension member)
A height extending member 140 for extending the height of the panels 110 and 120 is provided on each of the upper collars 112 and 122 of the two toe panels 110 and the two side panels 120 constituting the side wall panel of the transport pallet 100. It is detachably attached. As shown in FIGS. 2A to 2C, the extending member 140 is configured in an L shape in plan view.

That is, the extension member 140 is a first extension member 141 configured by a horizontally long rectangular frame attached to the upper collar 112 of the toe panel, and a second extension configured by a substantially square rectangular frame attached to the upper collar 122 of the side panel. A member 142 is provided. The lateral lengths of the first extending member 141 and the second extending member 142 are configured such that the first extending member 141 is longer.

The extension member 140 further includes an inclined member 145. The inclined member 145 is used to hold the extension member 140 in the unfolded state shown in FIGS. 2A to 2C and to hold the folded state shown in FIGS. 4E and 4F. The inclined member 145 is bridged obliquely between the first extending member 141 and the second extending member 142 in the expanded state of the extending member 140 in FIGS. 2A to 2C.

The lateral length of the first extending member 141 is configured to be equal to the sum of the lateral lengths of the second extending member 142 and the inclined member 145. This is because the second extension member 142 and the inclined member 145 are overlapped with the first extension member 141 in a state where the extension member 140 is folded as shown in FIGS. 4E and 4F described later.

The first extending member 141 and the second extending member 142 are connected to each other by mutually adjacent column members 141d and 142d by two upper and lower hinge portions 143. The first extending member 141 and the second extending member 142 are freely rotatable in the horizontal direction around the hinge portion 143.

On the lower horizontal member 141a of the first extension member 141, hook engaging portions 141b and 141c projecting downward are arranged. Also, the lower horizontal member 142a of the two extending members is provided with a hook engaging portion 142b projecting downward.

The two hook engaging portions 141b and 142b located at the end portions have a groove-like cross section with a downward opening, and the hook engaging portions 141b and 142b are covered with the upper hooks 112 and 122 of the toe panel 110 and the side panel 120. Thus, the first extending member 141 and the second extending member 142 are positioned. Another hook engaging portion 141c disposed in the middle of the lower horizontal member 141a of the first extending member 141 has an L-shaped cross section and abuts against the outer surface of the upper hook 112.

A lock member 144 for fixing the second extension member 142 to the upper collar 122 of the side panel 120 is disposed on the lower horizontal member 142 a of the second extension member 142. The locking member 144 includes a connecting plate 144a in which both ends of a support shaft 144a3 are supported by a bearing 142c disposed on the upper surface of the lower horizontal member 142a so as to be rotatable in the vertical direction, and a vertical direction on the outer surface of the lower horizontal member 142a. It is comprised by the L-shaped connection lever 144b attached to the rotation freely.

The connecting plate 144a is made of sheet metal having an L-shaped cross section, and is used to receive an engaging portion 144a1 that engages so as to embrace the lower surface of the upper collar 122, and a shaft portion 144b1 of the L-shaped connecting lever 144b. It has the notch part 144a2 inclined diagonally.

A cylinder for rotatably supporting the base end portion 145a of the inclined member 145 in the horizontal direction at the end opposite to the hinge portion 143 of the upper horizontal member 142e of the second extending member 142 as shown in FIG. -Shaped bearing portions 146 are arranged in the vertical direction. A base end portion 145a of the inclined member 145 is inserted into and supported by the bearing portion 146 from above. A retaining flange portion 145c is formed at the lower end of the base end portion 145a, and the base end portion 145a is movable up and down within a predetermined range in FIG.

A short cylindrical first engaged portion 147 and a second engaged portion that receive the L-shaped engaging portion 145b of the tip portion of the inclined member 145 at two locations inside the upper horizontal member 141e of the first extending member 141. 148 are arranged in the vertical direction. The first engaged portion 147 is welded to the upper end portion of the column member 141 h farthest from the hinge portion 143, and the second engaged portion 148 is located above the hinge plate 143 at a position relatively close to the hinge portion 143. It is welded to the horizontal member 141e.

Then, the extended member 140 is expanded at a right angle as shown in FIGS. 2A to 2C, and the expanded state is maintained by inserting and engaging the engaging portion 145 b of the inclined member 145 with the second engaged portion 148. I have to. Further, when the inclined member 145 is folded as shown in FIGS. 4E and 4F, the engaging portion 145b of the inclined member 145 is inserted and engaged with the first engaged portion 147 so that the extended state of the extending member 140 is changed. I try to keep it.

The inclined member 145 can be bridged obliquely between the lower horizontal member 141a and the lower horizontal member 142a, but there is a possibility that the inclined member 145 may interfere with the upper end portion of the cargo mounted on the floor panel 130. Therefore, it is desirable that the inclined member 145 is bridged obliquely between the upper horizontal member 141e and the upper horizontal member 142e.

The column member 142d of the second extending member 142 is formed of a rectangular pipe material having a sturdy rectangular cross section so that it can withstand the load at the time of stacking in FIG. A hemispherical convex portion 142d1 having the same shape as the hemispherical convex portion 21 at the upper end of the column member 121 of the side panel 120 is formed upward at the upper end portion of the column member 142d corresponding to the stacking. A hole 142d2 for receiving the hemispherical convex portion 21 at the upper end of the column member 121 of the transport pallet 100 is formed at the lower end of the column member 142d of the second extension member 142. The shape of the hole 142d2 is the same as the shape of the circular hole 131 on the bottom surface of the four corners of the floor panel 130 of the transport pallet 100.

(Attaching the extension member)
In order to attach the extension member 140 to the upper ridges 112 and 122 of the transport pallet 100, the extension member 140 expanded at a right angle as shown in FIGS. 2A to 2C is placed above the corner portion of the upper ridge 112 and 122 as shown in FIG. Lift to. Then, as shown in FIG. 5B, the lower end portion of the column member 142d of the second extending member 142 is positioned directly above the convex portion 21 of each corner portion.

Thereafter, as shown in FIG. 5C (a) → (b) → (c), the convex portion 21 at the upper end of the side panel 120 is fitted into the hole 142d2 at the lower end portion of the column member 142d, and the second extending member 142 is fitted. The hook engaging portion 142b of the lower horizontal member 142a is engaged with the upper hook 122. Similarly, the hook engaging portions 141 b and 141 c at the end of the lower horizontal member 141 a of the first extending member 141 are engaged with the upper hook 112 of the toe panel 110. As a result, the first extending member 141 and the second extending member 142 are positioned on the upper collars 112 and 122.

In the state of FIG. 5C (c), the extension member 140 can still be lifted from the upper collars 112, 122. Next, the lower horizontal member 142 a of the second extension member 142 is connected to the upper collar 122 by the lock member 144. That is, the shaft 144b1 of the connecting lever 144b is inserted into the inclined notch 144a2 of the connecting plate 144a as shown in FIG. 5D (a), and the connecting plate 144a is lowered around the support shaft 144a3 as shown in FIG. 5D (b). And the engaging portion 144a1 at the lower end of the connecting plate 144a is engaged with the lower surface of the upper collar 122.

Next, as shown in FIG. 5D (c), with the shaft portion 144b1 of the connecting lever 144b positioned at the innermost portion of the inclined notch portion 144a2, the connecting lever 144b is moved downwardly about the shaft portion 144b1 (clockwise in FIG. 5D). ) To the vertical position. As a result, the connecting plate 144a is pushed by the connecting lever 144b and pressed to the upper collar 122 side, and the lower horizontal member 142a of the second extension member 142 and the upper collar 122 are firmly connected. Since the connecting lever 144b is rotated downward to be in a vertical state, there is no possibility that the connecting lever 144b naturally loosens during transportation of the transport pallet 100 and the connecting plate 144a is released.

The locking member 144 can be disposed on the lower horizontal member 141a of the first extending member 141. In this embodiment, however, a handle latch 113 for connecting to the side panel 120 is arranged at the upper end of the toe panel 110. It is installed. Therefore, the lock member 144 is disposed on the lower horizontal member 142a of the second extension member 142 away from the handle latch 113 as described above for the space and ease of operation.

After the four extension members 140 are attached on the corner portions of the side wall panels 110 and 120, the first extension members 141 attached to the upper collars 112 of the two opposite toe panel 110 as shown in FIG. In between, the two ceiling beams 150 are bridged. As a result, the toe panels 110 are connected to each other via the first extending member 141.

The top beam 150 is made of, for example, a steel material having a groove-shaped cross section, and an engagement fitting 151 is fixed to both ends thereof. As shown in FIG. 6, the engagement fitting 151 has a pair of left and right engagement portions 152 having an L-shaped cross section, and the engagement portions 152 are the outer surface and the lower surface of the upper horizontal member 141 e of the first extension member 141. The top beam 150 can be prevented from lifting.

As shown in FIG. 7, the engaging portion 152 of the ceiling beam 150 is configured to be able to engage with the upper collar 112 of the toe panel 110, and the ceiling beam 150 is lifted in a state where the ceiling beam 150 is bridged between the upper collars 112. Is prevented. The upper collar 112 is also provided with a corner block 112f similar to a corner block 141f described later.

The engagement metal fitting 151 has a rectangular notch 153 between the pair of left and right engagement parts 152, and is disposed below the upper horizontal member 141 e of the first extension member 141 in the notch 153. A rectangular block 141f is fitted. By fitting the square block 141f to the notch 153, the engagement fitting 151 of the top beam 150 is restricted from moving laterally along the upper horizontal member 141e. The corner block 141f can be welded to the upper horizontal member 141e, welded to the reinforcing plate 141g disposed in the corner portion, or both.

In order to attach the top beam 150 to the upper horizontal member 141e of the first extension member 141, first, as shown in FIGS. 6A to 6B, the engagement fitting 151 at one end is set to the upper horizontal member 141 of the first extension member 141. Engage with the material 141e. Next, while pulling the upper horizontal member 141e of the other first extending member 141, the engaging metal 151 on the opposite side is engaged with the upper horizontal member 141e as shown in FIG. 6C. As a result, the square block 141f is fitted into the notch 153 of the engagement fitting 151 at both ends of the top beam 150, and the top beam 150 is positioned and fixed in the vertical and horizontal directions.

By using the extension member 140 as shown in FIGS. 1A to 1C, the height of the side wall panel can be freely extended. That is, only one type of height of the side wall panel is provided, and the height of the cargo that can be transported by attaching the extension member 140 in one or more stages corresponding to the height of the cargo to be transported. The range can be expanded.

For example, if the basic height of the side wall panel is set to 730 mm and the height of the extension member 140 is set to, for example, 360 mm, the height of the side wall panel can be set to 1090 mm by attaching the extension member 140 having a height of 360 mm in one step. The height of the side wall panel can be set to 1460 mm by attaching in two steps.

FIG. 7 shows a state in which another transport pallet 100 is stacked on the transport pallet 100 to which the extension member 140 is attached in one step. In this stacked state, the convex portion 142d1 of the upper end portion of the column member 142d of each corner portion of the extension member 140 is fitted in the hole portion 131 formed in the lower surface of each corner portion of the floor panel 130 of the upper transportation pallet 100. By combining, the upper and lower transport pallets 100 are positioned in the horizontal direction. The column member 142d of the extension member 140 is designed to have a cross section that can sufficiently withstand the load of the transportation pallet 100, so that two or more stages can be stacked.

(Folding extension member)
Next, how to fold the extension member 140 will be described. To fold the extension member 140, first, the inclined member 145 is lifted slightly upward as shown in FIG. 4A. That is, the inclined member 145 is lifted upward until the retaining flange portion 145 c at the end of the inclined member 145 contacts the lower end of the bearing portion 146. As a result, the engaging portion 145 b on the distal end side of the inclined member 145 can be pulled upward from the second engaged portion 148.

Next, as shown in FIG. 4B → FIG. 4C → FIG. 4D → FIG. 4E, the second extension member 142 and the inclined member 145 are rotated in the horizontal direction, and the second extension member 142 and the inclined member 145 are aligned with each other. Overlap inside the member 141. Finally, the engaging portion 145b on the distal end side of the inclined member 145 is inserted into the first engaged portion 147 as shown in FIG. 4E. Thus, the second extending member 142 and the inclined member 145 can be overlapped and fixed to the first extending member 141 without rattling.

FIG. 8 shows a state in which the extension member 140 is folded and flattened as shown in FIG. 4E or FIG. 4F and stacked in a horizontal state on the floor panel 130 for return. As described above, when the extension member 140 is folded, the extension member 140 becomes flat and compact. Therefore, the transportation cost can be reduced by carrying a large number of extension members 140 on one transportation pallet 100 and carrying out return transportation.

(Two-stage extension structure)
FIG. 9 shows an embodiment in which the extension member 140 is attached to each corner of the upper pallet 112, 122 of the transport pallet 100 in two upper and lower stages. Also in this case, the inclined member 145 of the extension member 140 is arranged in two stages in the upper and lower stages in a state of being obliquely bridged between the first extension member 141 and the second extension member 142 as shown in FIGS. 2A to 2C. Is possible. However, as shown in FIGS. 9 and 10A and 10B, the inclined member 145 is bridged as shown in FIGS. 2A to 2C in the upper stage, but the inclined member 145 is adjacent to the same side panel 120 in the lower stage. You may make it span between other extension members 140. FIG.

That is, as shown in FIG. 10A, a through vertical hole 145d is formed at a position near the tip of the inclined member 145, and the engaging portion 145b is inserted into and engaged with the through vertical hole 145d from above. As a result, the two adjacent extension members 140 are connected to each other via the respective inclined members 145, so that the attachment strength of the extension members 140 can be increased and the structural stability of the entire transport pallet 100 can be improved.

FIG. 10B shows an attachment member 145e having an L-shaped cross section attached to the side surface of the distal end portion of the extension member 140 by welding or the like, and a through vertical hole 145f is formed in the attachment member 145e. In this case, the engaging portion 145b at the tip of the extension member 140 can be inserted / engaged from above into the through vertical hole 145f of the mounting bracket 145e on the other side, thereby further increasing the connection strength between the extension members 140. The structural stability of the entire transport pallet 100 can be further enhanced.

As mentioned above, although embodiment of this invention was described, this invention can be variously deformed without being limited to the said embodiment. For example, in the above-described embodiment, the total of the lateral lengths of the second extending member 142 and the inclined member 145 is configured to be equal to the lateral length of the first extending member 141, but the first engaged portion 147 and If the position of the second engaged portion 148 is changed, the sum of the lateral lengths of the second extending member 142 and the inclined member 145 may not necessarily match the lateral length of the first extending member 141. Further, depending on the lateral lengths of the first extending member 141 and the second extending member 142, the position of the first engaged portion 147 that engages the engaging portion 145b on the distal end side of the inclined member 145 when folded in FIG. 4E. It is also possible to change to the middle portion in the longitudinal direction instead of the end portion of the first extending member 141.

In the above embodiment, the extension member 140 is a rectangular frame, but the extension member 140 may be a sheet metal plate or the like. In the above-described embodiment, the extension member 140 is disposed only at each corner portion of the side wall panel, but a configuration in which the extension member 140 is disposed without a break on the upper wall of the side wall panel is also possible.
