  1 to 4, reference numeral 1 denotes a resin pallet. The resin pallet 1 is configured such that a base plate 2 on which a load is loaded and a load loaded on the plate 2 are fixed to the base plate 2 with a strap 3. The base plate 2 has a hollow double wall structure formed by blow molding a thermoplastic resin. The hollow double-walled base plate 2 is formed with concave ribs 6 and 7 in which the front wall 4 and the back wall 5, which are opposite walls thereof, are recessed in a concave shape, and the tip portions thereof are welded and integrated. It is. The welding wall 8 in which the concave ribs 6 and 7 are integrated with each other is a portion in which the front wall 4 and the back wall 5 are integrated together, and is thus thick. The thick welding wall 8 is provided with an attachment hole 10 for attaching an anchor bolt 9 which is a locking member for tying or hanging the strap. The anchor bolt 9 has an annular head portion 12 through which a strap is passed at the upper end of the shaft portion 11, and a distal end side of the shaft portion 11 is a male screw 13. The anchor bolt 9 is inserted into the mounting hole 10 from the front wall 4 side of the base plate 2 and the nut 14 is fastened to the male screw portion 13 from the back wall 5 side, thereby attaching the anchor bolt 9 to the base plate 2. The annular head 12 of the anchor bolt 9 protrudes from the front wall 4 of the base plate 2. The anchor bolt 9 can be attached to and detached from the base plate 2 by attaching and detaching the nut 14. 15 is an object to be loaded and 16 is an inclusion. The inclusion 16 is a wooden board, a foamed resin board, a buffer material or the like.

  As shown in FIG. 2, the base plate 2 is covered with a box-shaped cover body 17, and for this reason, a concave groove 18 into which the opening end of the cover body 17 is fitted is formed in the periphery of the base plate 2. The base plate 2 can be covered with a cover body 17 in an immobile state. In addition, although the cover body 17 is provided with the structure latched to the base plate 2 by a suitable latching means, it is not illustrated. The cover body 17 is used as necessary. The molding means for the base plate 2 is preferably blow molding, but is not necessarily limited thereto and can be based on other molding methods.

  In the resin pallet 1 according to the present invention, as shown in FIGS. 5 and 6, the base plate 2 can have leg portions 19. Reference numeral 20 denotes a fork of the forklift. Further, the base plate 2 does not necessarily have a hollow double wall structure, but this is not shown. In the present invention, the strap 3 is a generic term for a string that can be used for fixing the load 15 such as a string, a belt, a wire, a chain, or the like.

  In the illustrated embodiment, the base plate 2 is provided with a plurality of concave ribs 6 and 7 distributed almost over the entire surface to form a reinforcing structure of a hollow double wall structure. If it is set as the structure which provides many concave ribs 6 and 7, the base plate 2 can ensure required intensity | strength and rigidity altogether with respect to the load by the to-be-loaded object 15 by the reinforcement effect of the peripheral part. Then, as described above, the straps 3 are formed on the base plate 2 according to the form and size of the load 15 by providing a large number of concave ribs 6 and 7 over the entire surface in a dispersed manner or in a concentrated manner on the periphery. The required number of anchor bolts 9 can be attached at a suitable position for tying or securing by fastening.

  In the resin pallet 1 according to the present invention, since the concave ribs 6 and 7 are provided in a distributed manner over almost the entire surface of the base plate 2, anchor bolts 9 are attached according to the form and size of the load 15. The position can be appropriately selected appropriately. Then, as illustrated in FIGS. 7 to 9, the inclusion 16 can be held in an immobile state by mounting the anchor bolt 9 so as to surround the plate-like inclusion 16. It is more preferable that a locking recess 21 to be locked to the bolt 9 is formed. As described above, since the inclusion 16 interposed between the base plate 2 and the load 15 can be held in the base plate 2 in a stationary state, the inclusion 16 is displaced on the base plate 2 during transportation and transportation. There is no fear of causing it, and the fixed state of the load 15 by the strap 3 can be reliably held. Since the inclusion 16 is interposed between the load 15 and the base plate 2, the load 15 slides on the base plate 2 during transportation or transportation when there is no inclusion 16. Can be prevented.

  7 and 8 each illustrate a mode in which one load 16 is loaded, and FIG. 9 illustrates a mode in which two loads 16 are loaded. In the resin pallet 1 according to the present invention, the loading mode of the load 15 is not limited to the illustrated example, and can be an appropriate loading mode.

  The thermoplastic resin constituting the base plate 2 of the resin pallet 1 according to the present invention is a polyolefin resin such as polyethylene, polypropylene, polystyrene, polyamide resin, polyethylene terephthalate resin, polybutylene terephthalate resin, polystyrene resin, ABS resin. Polycarbonate resin, modified polyphenylene oxide resin, or blends thereof are thermoplastic resins with excellent rigidity that can be blow-molded.

  The resin pallet 1 according to the present invention includes a base plate 2 on which an object 15 can be loaded and a lower surface can be supported by a fork of a forklift, and a cover body 17 that covers the object 15 on the base plate 2. Since the cover body 17 has a locking structure that is fixed by being fitted into a concave groove 18 provided in the peripheral portion of the base plate 2, the cover body 17 is stacked on the base plate 2 and fixed with the strap 3 as described above. The loaded object 15 can be protected by covering the whole with the cover body 15. Since the base plate 2 on which the load 15 is loaded is provided with a large number of dispersed portions of the strap 3 for fixing the load 15, the shape of the load 15 to be loaded is limited. In addition, it is possible to load a plurality of objects to be loaded 15 without being received, and it is excellent in the versatility of the packaging and loading mode and the workability for fixing the objects to be loaded 15 is also excellent.
