Problems solved by technology

[0007] However, in the case where the opposite ends of the tray are supported, and the tray is loaded, there is a problem in the above-mentioned synthetic resin tray, because the four corners of the fork-shaped socket 206 are subject to enormous bending stress, the fork-shaped socket 206 206 is easily deformed into a parallelogram and the entire pallet is easily bent compared to wooden pallets

no. 1 approach

[0040] Figure 1-Figure 6 The synthetic resin tray which shows the 1st Embodiment of this invention. figure 1 is a top view, figure 2 is the bottom view, image 3 is the front view, Figure 4 is the side view, Figure 5 yes figure 1 A section along the A-A direction, Image 6 is the section along the B-B direction.

[0041] In general, the synthetic resin pallet of this embodiment is box-shaped, and has a square upper floor portion 1 and a square lower floor portion 2 arranged parallel to each other, and beams 3, 4 connecting the upper floor portion 1 and the lower floor portion 2. and 5. Beams 3 are formed at the four corners of the upper floor portion 1 and the lower floor portion 2, beams 4 are formed at the center of the four sides of the pallet, and beams 5 are formed at the center section of the pallet. All beams consist of many vertical walls.

[0042] In the side faces of the four sides of the pallet, each pair of rectangular fork-shaped sockets 6 is formed...

no. 2 approach

[0073] then, Figure 9-Figure 12Shows the second embodiment of the present invention. Parts corresponding to those of the first embodiment are denoted by the same reference symbols, and explanations are omitted.

[0074] The main difference is that in the first implementation, as Image 6 As shown, a hollow portion 70' is formed along the entire periphery of the reinforcement frame 70, and in this embodiment, as Figure 11 As shown, the hollow portion 70' is formed in only one portion of the reinforcement frame 70.

[0075] Such as Figure 10 with 11 As shown, the reinforcing frame 70 of the second embodiment has an upper horizontal beam 71 surrounding the four ends of the fork socket 6, vertical beams 73 and 74, and a lower horizontal beam 72c. In this embodiment, only the opposite side portion of the lower horizontal beam 72c is made hollow and connected to each hollow portion of the vertical beams 73 and 74 . Therefore, the four corners of the reinforcing frame 70 are...

no. 3 approach

[0084] then, Figure 15 Shows the third embodiment of the present invention. Parts corresponding to those of the first embodiment are denoted by the same reference symbols, and explanations are omitted.

[0085] In the first and second embodiments, the reinforcement frame 70 is formed only between the beams 3 at the four corners and the beams 4 at the middle portions of the sides. However, the third embodiment is characterized in that reinforcing frames 70 are formed between the beams 4 at the middle portion and the beams 5 at the center of the pallet, respectively. The structure of these added reinforcement frames 70 has the same structure as either of the reinforcement frame 70 of the first embodiment or the reinforcement frame 70 of the second embodiment. Some reinforcement frames 70 may have the same structure as the first embodiment, and other reinforcement frames 70 may have the same structure as the second embodiment.

[0086] In the first embodiment and the second e...

Abstract

A synthetic resin pallet, comprising square-shaped upper platy part (1) and a lower platy part (2) and girder parts (3), (4), and (5) for connecting the upper and lower platy parts (1) and (2) to each other, wherein fork inserting ports (6) are formed in the side face of the pallet between the girder parts (3) and (4), a plurality of rectangular reinforcing frames (70) surrounding the cross-sections of the fork inserting ports (6) crossed perpendicular to a fork inserting direction are formed in the fork inserting ports (6), respectively, and a hollow part (70') is formed in the reinforcing frames (70) through at least three sides of each of the reinforcing frames (70).

Description

technical field [0001] The present invention relates to a synthetic resin pallet used in transporting and storing various articles and the like. Background technique [0002] Conventionally, wooden baseboards have been used when transporting and storing items, but recently, synthetic resin pallets are becoming more and more popular because they have many advantages, namely, they are lighter than wood, are not easily corroded, and do not produce as Chipping of wood features. In particular, integrally molded trays in which upper and lower surfaces are integrally molded are used instead of wooden trays in a wide range of fields because of its high production efficiency. [0003] This type of synthetic resin tray, as in Figure 23 As shown in , there is a square upper base plate portion 200 and a lower base plate portion 202, and a plurality of beams (columns) 204 connecting the upper base plate 200 and the lower base plate 202, and a pair of columns parallel to each other are ...
